Description

Technical Field

[0001] The present disclosure relates to the field of utility tools, and more particularly to modular components that can be removably engaged into various assembled configurations for use in engaging and / or supporting and / or operating and / or transporting tools for a number of utility purposes.

Background Art

[0002] Utility tools in various forms are essential for every industry and can be extremely diverse in both size and complexity to meet the specific needs of the selected industry. Regardless of the industry, most utility tools are designed to have a single function. Therefore, various utility tools are required to meet the various needs of the selected industry.

[0003] The film production industry is an example of an industry that requires various specialized utility tools. Cinematic techniques in film production, video shooting, and photography are increasing in both scale and complexity. Such cinematic techniques rely on a wide range of utility tools, especially camera support tools, which provide filmmakers with the technical means to generate the camera shots required for a scene or projection effect. Additionally, due to the required portability and versatility of film set tools, a variety of carts, hand trucks, stands, etc. are needed to perform efficient movement at the workplace.

[0004] A wide variety of camera and motion support devices are available and widely used by filmmakers and photographers. Some commonly used devices include jibs or cranes, which provide the ability to add vertical and lateral movement to a shot, and depending on the size of the jib, they have the ability to achieve high-angle shots. Similarly, various types of dollies exist in a range of sizes, from very large to compact systems, to allow for the addition of horizontal movement to a shot by providing smooth rolling camera movement. Portable body-supported stabilizers and gimbals allow operators to shoot smooth shots while walking, while maintaining the ability to control camera pan and tilt movements. Another example is the slider, which is essentially a simplified dolly that can be mounted on a supported track, providing smooth movement along a straight path.

[0005] Each type of camera mount is designed to enable a specific camera angle or dynamic movement. In this way, each type of camera mount is designed to provide specific functionality for achieving a particular type of shot, taking into account the challenges of a particular shooting location. Therefore, the functionality and usefulness of each type of camera mount are limited, and as a result, the use of multiple types of camera mounts is often required in a given project. The limited versatility of camera mounts means that each type can typically be used individually, and sometimes in various combinations, to provide filmmakers with several options for achieving a scene or effect. However, these options are often difficult to coordinate due to space limitations, the typically large and bulky size of the equipment, and the cumbersome nature of transporting and setting up the equipment, which requires time, cost, and effort.

[0006] While current systems attempt to address the challenges of portability and installation / disassembly of camera mounts, there remains a need for a system that is easy to transport and assemble, and also offers versatility and multifunctionality to support creative camera angles and movements without necessarily requiring a large variety of mounts.

[0007] The shortcomings observed in camera mounting fixtures are also common in utility fixtures in other industries such as construction and production. [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] This disclosure relates, more broadly, to modular utility system assemblies for engaging, supporting, operating, and moving tools, implements, equipment, and other types of loads.

[0059] The modularity of the components and assemblies disclosed herein enables and facilitates the customization of utility assemblies. According to some embodiments disclosed herein, a customizable kit is provided comprising a number of different modular components that can be assembled into a selected or specific type of desired utility assembly and / or support assembly. In this way, the modular components, assemblies, and systems of the disclosed herein provide field versatility and ease of use. For the purpose of illustrating the versatility, ease of use, and configuration of the modules, the following description (but not limited to) refers to examples of utility assemblies that are useful for detachable engagement with cameras, sound equipment, lighting equipment, props, and other types of equipment used in filmmaking, videography, and photography applications, and are also useful in some common utility cart applications and some common work station applications.

[0060] To illustrate various types of detachably engaging modules that can be reliably and stably interconnected and assembled into numerous different configurations for engaging, supporting, and transporting various types of utility equipment and / or tools and / or devices and / or components and / or parts and / or materials and / or supplies in movie sets or production studios or photography studios or performance venues or sports venues or other locations commonly used for filming movies, videos, television programs, sports, news, documentaries, music videos, time-lapse photography, and still photography, several examples of embodiments of the module components and module assemblies of this disclosure will be described with reference to Figures 1 to 33. Those skilled in the art will be able to understand how to reliably and stably engage the modules and module assemblies disclosed herein for assemblies that are useful in other types of settings such as construction, landscaping, agriculture, industry, healthcare, retail, warehousing, etc., or for use in some home and entertainment applications. The number and types of modules that can be incorporated into a particular assembly will vary depending on the intended end use of the utility or support system. However, the assembled system generally includes one or more groups of rotator modules as illustrated in Figures 1 to 5, one or more groups of joiner modules as illustrated in Figures 6 to 12, one or more groups of male member mount modules as illustrated in Figures 13 to 15, one or more groups of hub modules and hub assemblies as illustrated in Figures 3, 5 to 7, 11, and 13 to 15, one or more groups of tool / load support modules as illustrated in Figures 16 to 20, one or more groups of base modules as illustrated in Figures 21 to 27, and one or more groups of end cap modules as illustrated in Figures 28 to 33.

[0061] Modules can be used to assemble various utility systems and support structures, such as dollies, carts, tracks, stands, tables, work stations, seats, shelves, bed frames, railings, stages, and partitions. Figures 34 to 48 show examples of various types of utility and support assemblies that can be constructed by combinations of the modular components and modular assemblies disclosed herein.

[0062] It should be noted that all modules disclosed herein provide flexible interoperability to a variety of utility system assemblies to provide a wide range of functional capabilities or special functions. After the need for the assembly has ended, the assembly can be easily disassembled into individual module components for transport and / or storage. For example, base plate modules and assemblies, such as the base plate modules and assemblies illustrated in Figures 16 and 17, are useful for mounting cameras, microphones, or such instruments or tools. According to other embodiments, one or more tray modules and one or more table / desk modules (Figures 18 and 19) can be configured to transport instruments, materials, consumables, etc., in a location and can be configured as a movable or stationary work station. One or more lighting mount modules (Figure 20) can be incorporated into a utility system assembly to detachably engage lighting or sound or other similar instruments. According to other embodiments, a wheel module (Figure 23) can be configured to provide a rolling function to the system assembly, or foot modules (Figures 24 and 25) can be incorporated in a fixed arrangement. In other embodiments, the system assembly may comprise one or more rail-rolling modules (Figures 21 and 22) that can move or pass through the system over an extended length or a series of rail track assemblies (see Figures 34, 35, 36, 39, and 43). Furthermore, a weight module (Figure 26) may be incorporated into the system as needed for structural balance and base stability options. In addition, the system assembly may include one or more telescopic extension modules (Figure 27). Furthermore, one or more groups of end cap modules (Figures 28 to 33), including components and modules of handles, feet, pads, seats, bumpers, and caps, may be provided within the system for functioning to various end-use requirements.

[0063] Detachable engagement mechanism An important feature of embodiments of this disclosure relates to a mechanism that enables and facilitates rapid, stable, and secure engagement of one module with another in order to securely and stably fasten modules together with one another. Some of the modules disclosed herein have one or both ends configured to provide a functional pivot point that allows for 360° rotational movement at one or both ends.

[0064] Figures 1 to 33 show various typical interconnection modules that generally embody the structural components and frameworks of typical utility systems and support structures disclosed herein. Each of these modules comprises all or part of a reversible coupling mechanism according to embodiments of this disclosure and is referenced for illustrative purposes. It will be understood that all or part of the various embodiments of the reversible coupling mechanism can constitute components of any module to enable interconnection to a larger system according to embodiments described herein. The reversible coupling mechanism may comprise a receptacle in one module as shown in units 11, 211, 252, the receptacle being configured to receive and engage with a male member having a male component 70 of another module.

[0065] The male component 70 generally comprises a first collar 87a (i.e., distal collar) having a chamfered leading edge 86 that functions as a retaining lock chamfer, and a neck portion 88 separating the first collar 87a from a second collar 87b (i.e., proximal collar). Four projections 82 extend radially outward from each of the collars 87a and 87b. The projections 82 are configured to slide-engage, for example, projection-retaining slots 223 provided in the jointer receptacle 211 (Figure 6), or projection-retaining slots 262 provided in the transverse-opening jointer receptacle 252, or projection-retaining slots 630 provided in the grip end cap module 625 (Figure 28). Alternatively, the projections 82 may be free within the rotator receptacle 11 (Figures 1, 3, and 5), allowing for a full 360° rotation of the male component 70 within the receptacle 11. The male component may have 2 to 8 collars spaced apart from each other to engage with a receptacle configured to accept and engage with the male component, and each collar may have 2 to 12 spaced-apart projections 82 extending outward from each other.

[0066] Some of the modules disclosed herein may have a receptacle 11 in a housing 15 provided with a reversible coupling mechanism having a pivot lock 60 for detachable engagement with the male end of another module. In one embodiment, the module housing may have two or more pivot locks 60 spaced apart from each other and arranged around the outer periphery of the module housing. As shown in Figure 2, some modules may have a pivot lock 60 having a pivot lock indexing peg 62 for reversibly locking the module to a second module, the indexing peg 62 extending to pivot lock sprockets 74, 112, 216, 272, 284, 362, 396, 423, 506 (Figures 1, 3, 6, 9, 10, 13, 15, 16, and 20, respectively). A pivot lock sprocket may have 16 slots around its outer edge, providing 16 locking positions at intervals of, for example, 22.5°.

[0067] Rotator Module Typical rotator modules shown in Figures 1-5, 26, and 29 are provided with a reversible coupling mechanism as disclosed herein, enabling the module to be reversibly interconnected with other modules in the system. The rotator module is configured to provide rotational functionality to various pivotable connection points between selected modules at different locations in the assembly. According to some embodiments, the rotator module can provide pan and / or tilt functionality to a tool support module or load support module or tool support assembly or load support assembly, and to a device such as a camera or other load mounted thereon. The rotator module can also provide other functional pivot points in the assembly, such as directional rotation and / or drive rotation of a wheel module.

[0068] According to some embodiments, a tool support assembly or load support assembly may comprise one or more groups of closed-tube rotator modules having various lengths, which may be dimensioned relative to the unit scale of the entire system format to help facilitate the interoperability of the system modules. For example, a closed-tube rotator module may have a length of 2 units and a diameter of 2 units, with 1 unit being 30 mm.

[0069] Examples of closed-pipe rotator modules 10 with a length of 2 units / a diameter of 2 units are shown in Figures 1 and 2, and in Figure 3B, they are illustrated reconfigured as a 6-way closed-pipe rotator hub assembly 101 with a length of 2 units / a diameter of 2 units. These closed-pipe rotator modules include a rotator receptacle 11 configured to securely and detachably engage with a second module, the male end of the second module being able to rotate 360° within the receptacle 11. Closed-pipe rotator modules 10, 100, 101 may include a closed-pipe housing 15, which in this example provides a module length of 2 units when the rotator receptacle assembly 20 (Figure 5) is secured within the closed-pipe housing 15 by four screws 23 in four threaded pipe end screw slots 18. A typical rotator receptacle assembly 20 comprises a lock spring rotator half socket 21 and a unlock rotator half socket 22 which work together to define (i) an outer bush channel 24 for an outer bush 26, (ii) an inner bush channel 28 for an inner bush 30, (iii) a pivot lock channel 32 for a typical pivot lock 60, and (iv) a square nut slot 34 for securing a square nut 36 within the closed tube housing 15 so as to align with either a retaining lock 50 or a lateral mounting hole 38.

[0070] In these examples, a square nut slot 34 is provided to receive a square nut 36 that can be screwed onto a retaining lock set screw 40. The retaining lock set screw 40 enters through a retaining lock set screw hole 42 in the closed-pipe housing 15, passes through the nut 36 into the rotator receptacle assembly 20, and engages with the retaining lock 50 depending on the position of the set screw. The retaining lock 50 comprises a retaining half-lock 52 with a spring receptacle and a retaining half-lock 54 with a release button. The spring 56 engages with the inside of the locking spring rotator half-socket 21 within the retaining half-lock 52 with a spring receptacle, pressing the retaining half-lock 52 toward the center of the receptacle relative to the retaining half-lock 54 with a release button. The degree of movement away from the center of the receptacle resisting the spring 56 can be limited by using a tension adjustment screw knob 58 or other screwdriver to ensure that the retaining lock set screw 40 advances toward the retaining half-lock 52. The operator can move the retaining lock 50 by manually pressing the retaining lock release button 55 on the retaining half-lock with release button 54 through the release button hole 44 of the closed pipe housing 15. Since the retaining lock 50 is now irremovable when the set screw 40 is fully engaged, removal of the cooperating male component 70 is prevented until the retaining lock set screw 40 is loosened, as will be explained in more detail below.

[0071] Any one of the group of male components 70 located on the cooperating modules of the system can be detachably fixed and pivotably engaged within the rotator receptacle 11 of the rotator modules 10, 151, 605, 640. Referring to Figures 1 and 2, the closed-pipe rotator module 10 may include the male components 70, the closed-pipe housing 15, the pivot lock sprocket 74, and a wide pivot segment 78 that cooperates with the outer bush 26 in the rotator receptacle 11 of the other modules in terms of rotation.

[0072] The proximal end of the male component 70 has an octagonal recess 81, which allows the male component 70 to be attached to a larger assembly having an octagonal boss 79 (first visible in Figure 3A) on the end face of a wide pivot segment 78, or to a typical male member lateral mount assembly 110 (first visible in Figures 3A and 3B) where an octagonal boss 118 is shown on the wide pivot component 116. The octagonal connection point allows the male component 70 to be reversibly attached to the support module in two orientations.

[0073] As shown in Figure 2, the male component 70 can be provided with eight projections 82 in four linear sets of two projections 82, and each set of projections is arranged at equal intervals of 90° around the outer circumference of the male component 70, thereby enabling the male component 70 to be detachably engaged with the receptacles 11, 211, and 252 (Figures 1, 6, and 8A, respectively).

[0074] When detachably engaged with the rotator receptacle 11, the outer cylindrical portion of the male component 70, i.e., the slender pivot segment 84 (shown in Figure 2), cooperates with the inner bush 30 of the receptacle 11 in terms of rotation. The male component 70 has two collars (distal collar 87a and proximal collar 87b) that define the neck portion 88 (Figure 2). The leading edge 86 of the distal collar 87a is chamfered (86 is hereafter referred to as the retaining lock chamfer), which pushes back the retaining half-lock 52 with the spring receptacle, allowing the male component 70 to enter the receptacle 11 or the receptacle 211 (Figure 6). The spring-receptacle-equipped half-lock 52 remains pushed back until the distal collar 87a and the four outer projections 82 on the male component 70 pass through the half-lock 52, after which the male component 70 is held in the receptacle 11 by the tension of the spring 56 cooperating with the half-lock 52 as the half-lock 52 aligns with and engages with the neck portion 88. The operator can manually release the retaining lock 50 and allow the cooperating modules to be separated by pressing the release button 55 through the release button hole 44 of the closed-tube housing 15, which moves the retaining half-lock 54 with the release button inward, thereby pushing the retaining half-lock 52 with the spring-receptacle-equipped half-lock 52 outward against the spring 56 and separating the retaining lock 50 from the neck portion 88 of the cooperating male component 70.

[0075] The retaining lock set screw 40 can be used to adjust the tension that the half-lock 52, with its spring 56, applies to the neck portion 88 of the male component 70. The position of the set screw 40 relative to the half-lock 52 can be adjusted and secured using a tension adjustment screw knob 58 (shown in Figure 1) or another type of screwdriver via a retaining lock set screw hole 42 provided in the closed-pipe housing 15, using a square nut 36 housed in a square nut slot 34 provided in the lock spring rotator half socket 21. The retaining lock set screw 40 can be adjusted between a retracted position and an engaged position to provide varying degrees of friction in the pivotable contact between the neck portion 88 and the retaining lock half 52, or it can be adjusted to prevent the removal of the male component 70 until the set screw 40 is retracted and can push back against the spring 56 to allow the half-lock 52 to be removed from the receptacle 11 of the male component 70, thereby stopping the rotation of the male component 70 and preventing the movement of the retaining lock 50 when fully engaged.

[0076] The neck portion 88 of the male component 70 may optionally be provided with one or more spaced-apart screw holes 89 to enable engagement of the lateral connector screw 265 in the male / receptacle lateral opening jointer module 251, for example, as shown in Figure 8. In use as shown in the example in Figure 8, the neck portion 88 has four equally spaced screw holes 89, providing four possible fixing positions for the male component 70 in the lateral opening jointer receptacle 252.

[0077] According to one embodiment of the present disclosure, the male component 70 can be engaged with the closed-pipe housing 15 by a connector screw 90 that screws into a central threaded hole in the wide pivot segment 78, as shown in Figures 1 and 2. The assembly of the male component 70 engaged with the wide pivot segment 78 will hereafter be referred to as the male member closed-pipe end assembly 71. According to another embodiment of the present disclosure, the male component 70 can be engaged with a wide pivot component 116 and a pivot lock sprocket 112 to form a male member lateral mount assembly 110. As shown in Figure 3, the male member lateral mount assembly 110 can be detachably engaged with the closed-pipe housing 15 by bolts 120 that pass through the lateral mount holes 38 of the housing 15 at up to four of the seven lateral mount holes 38 (Figures 2 and 3) in this example, or, in other modules, screw into square nuts 36 fixed in square nut slots 34 of the rotator half socket 21 or half socket 22.

[0078] According to another embodiment of the present disclosure, the slender pivot segment 84 of the male component 70 can cooperate with the inner bush 30 of the receiving rotator receptacle 11 (Figure 2) in terms of rotation. Furthermore, the cylindrical surface of the wide pivot segment 78 or wide pivot component 116 can cooperate with the outer bush 26 (Figure 2) mounted inside the receptacle 11 in terms of rotation.

[0079] According to other embodiments of the present disclosure, for example, as shown in Figures 1 to 5, Figure 26, and Figure 29, the rotator modules 10, 151, 605, 640 may include a pivot lock 60 having a pivot lock indexing peg 62 set within a pivot lock button 64 used to detachably engage the rotator modules 10, 151, 605, 640 with another module. The pivot lock 60 can be engaged or disengaged by pressing down the pivot lock button 64 and lowering a lock retaining tab 65 into and out of a recess in the pivot lock channel 32. The operator then manually slides the pivot lock button 64 to the locked or unlocked position and releases the downward deflection manually applied to the pivot lock button 64, causing the lock retaining tab 65 to return upward and hold the pivot lock 60 in the position within the opening of the lock or in the downward position in the recess of the pivot lock channel 32. In this example, the two lateral teeth at the base of the pivot lock button 64 protrude into two pairs of corresponding recesses on either side of the pivot lock channel 32 to help hold the pivot lock 60, and flex inward in response to the sliding force applied by the operator, allowing the pivot lock button 64 to move between each position.

[0080] The engagement of the pivot lock 60 in this manner allows the indexing peg 62 to extend to a pivot sprocket having 16 side-open pivot lock slots around its outer edge, providing 16 locking positions at 22.5° intervals around the male component 70 on the other module that engages with the module, and the indexing peg 62 can reversibly lock the pivot of the male component 70 of the other module at the receptacle 11 of the rotator module. A typical male member closed end assembly 71 (Figure 2) including the feature portion of the closed pipe housing 15 may include a pivot lock sprocket 74 having pivot lock slots around the base of a wide pivot segment 78 (Figure 1A). Similarly, as shown in Figure 3B, the male member lateral mount assembly 110 may comprise a pivot lock sprocket 112 having pivot lock slots around its outer edge and two small teeth on its open inner circumference, the pivot lock sprocket 112 being fixed to the cylindrical body of module 101 by a wide pivot component 116, the wide pivot component 116 having two retaining slots in its concave bottom corresponding to the teeth of the pivot lock sprocket 112 that hold the components together when the pivot lock sprocket 112 and the wide pivot component 116 are fixed to the round side of module 101 by bolts 120 that screw into square nuts (not shown) in the closed pipe housing 15.

[0081] According to some embodiments, the rotator module disclosed herein may have seven lateral mounting holes 38 arranged at 45° intervals around the outer circumference of the module, except where the pivot lock 60 is located. The arrangement of the lateral mounting holes 38 allows the assembly, collectively referred to herein as the closed-tube rotator hub assembly 100, to be configured with one, two, three, or four male member lateral mounting assemblies 110 mounted as shown in Figure 3, at various angular directions and degrees of spacing. As shown in Figure 2, the lateral mounting holes 38 aligned with the joints of the two rotator socket halves 21, 22 located opposite the pivot lock 60 require threaded inserts within the wall of the closed-tube housing 15 because they need to be opened in recesses in the socket halves, corresponding to the square nut channels 170 in embodiments where the rotator receptacle assembly 20 is housed within the extension-tube housing 155 as shown in Figure 5.

[0082] Several examples of double-receptacle extension tube rotator modules 151, 152, and 605 are shown in Figures 4, 5, and 26, with all three modules having a rotator receptacle 11 at each end. Modules 151 and 605 are shown without the male member lateral mount assembly 110 attached (Figure 4). Module 152 is shown engaged with two male member lateral mount assemblies 110 (Figure 5) and is referred herein to as a four-way double-receptacle extension tube rotator hub assembly 152, providing four interconnection points with other modules of the system assembly.

[0083] The double-sided receptacle extension tube rotator module according to the embodiments of the present disclosure is formed by a rotator receptacle assembly 20 having the same components and functions as described above, and comprises a rotator receptacle 11 that is securely fixed within each end of the extension tube housing 155 by four screws 23 that are inserted into four threaded tube end screw slots 168 in the inner wall of the extension tube housing 155 (Figures 4 and 5). According to some embodiments, in accordance with the two unit diameters and several other features of the closed-tube housing 15 described above, the extension tube housing 155 may have two retaining lock set screw holes 162 for adjusting the retaining lock set screw 40 of each receptacle, two release button holes 164 for manual access to the release button 55 of each retaining lock, and a number of lateral mounting holes 160 (two sets of six holes in the embodiments shown in Figures 4 and 5) corresponding to the number and position of the square nuts 36 housed in the housing 155 and receptacle assembly 20 for configurably mounting up to four male member lateral mounting assemblies 110 around the extension tube housing 155.

[0084] According to other embodiments disclosed herein, the male member lateral mount assembly 110 can also be mounted at an intermediate point along the extension tube housing by a plurality of lateral mount holes corresponding to the same number of square nuts 36, which are securely held within the tube housing by an intermediate square nut holder having a plurality of matching square nut slots for aligning and positioning each square nut in a lateral mount hole. Referring to Figure 5, the intermediate square nut holder 180 can be positioned within the extension tube housing 155 by positioning the inward edge of the square nut channel 170 of the housing within the same number of tube rail channels 182 on the side of the intermediate square nut holder 180 until the holder 180 is aligned with the set of six available lateral mount holes 160, by an alignment thread rod (not shown) that optionally engages in a threaded hole 184 for holding and moving the holder 180 during assembly. To prevent undesirable movement of the intermediate square nut holder 180, once it is in position, a short positioning set screw 186 can be inserted into the available lateral mounting hole 160 when the lateral mounting assembly 110 is not engaged. The intermediate square nut holder may include crush ribs on its outer edge to prevent undesirable movement within the extension tube housing.

[0085] In addition to providing engagement with the pipe rail channel 182, the square nut channels 170 located at two positions on the outer circumference of the extension pipe housing 155 provide openings into which one or more square nuts 36 can be inserted and slid along the channel 170, and thus can be used to enable various specific hub assemblies by detachably engaging additional male member lateral mounting assemblies 110 with bolts 120 at various positions along the extension pipe housing 155.

[0089] Optionally, to allow for additional options for configuring various detachable engagement options by multiple pivot male member lateral mounting assemblies, it is possible to provide multiple equally spaced intermediate square nut holders 180 aligned with additional lateral mounting holes 160 in extension tube housings having lengths ranging from 4 cm to 240 cm.

[0090] Joiner Module A Joiner Module, as disclosed herein, is a component or module assembly of a structural system configured to be detachably combined with a Rotator Module or other modules for assembling various tool support structures or load support structures that may be fixed in place and immovable, or movable in cooperation with rollers, wheels, or casters. A Joiner Module, as disclosed herein, is detachably interconnected with one or more Rotator Modules, and / or one or more Tool Support Modules, and / or one or more Load Support Modules, and / or one or more Base Modules, and / or one or more End Cap Modules.

[0091] Examples of several embodiments of the joiner module of this disclosure are shown in Figures 6 to 12. Some embodiments relate to a joiner module comprising a joiner receptacle and a male end on the opposite side. Some embodiments relate to a joiner module further comprising an elongated structural element interposed between the joiner receptacle and the male end. Some embodiments relate to a joiner module comprising two oppositely oriented male ends. Some embodiments relate to a joiner module further comprising an elongated structural element interposed between the two oppositely oriented male ends. Some embodiments relate to a joiner module comprising two oppositely oriented joiner receptacles. Some embodiments relate to a joiner module further comprising an elongated structural element interposed between the two oppositely oriented joiner receptacles. A joiner module comprising an elongated structural element may optionally be called an extension tube joiner module.

[0092] It should be noted that the elongated structural elements of the jointer module may be tubes or rods having a circular, elliptical, square, rectangular, trapezoidal, triangular, hexagonal, octagonal, decagonal, or I-shaped cross-section. The length of the elongated structural elements of the Joiner Module can be selected from a range of 2cm to 240cm, such as 2cm, 4cm, 5cm, 6cm, 8cm, 10cm, 15cm, 20cm, 25cm, 30cm, 35cm, 40cm, 45cm, 50cm, 55cm, 60cm, 65cm, 70cm, 75cm, 80cm, 85cm, 90cm, 95cm, 100cm, 110cm, 120cm, 130cm, 140cm, 150cm, 160cm, 170cm, 180cm, 190cm, 200cm, 210cm, 220cm, 230cm, 240cm, and in between.

[0093] Some embodiments relate to a joiner module that detachably engages with an elongated structural support component or element and further comprises one or more male member assemblies extending radially from the elongated structural support component or element. Such a joiner module may be called a joiner hub module or joiner hub assembly.

[0094] An example of a closed-pipe jointer module shown in Figure 6A, sometimes referred to herein as a closed-pipe jointer hub assembly 201, comprises a jointer receptacle 211 formed by a jointer receptacle assembly 220 housed within a jointer closed-pipe housing 215 having a pivot lock sprocket 216, and a male component 70 extending outward along the longitudinal axis of the jointer closed-pipe housing 215. A male member lateral mount assembly 110 is detachably engaged with the side of the jointer closed-pipe housing 215 and is shown extending radially from the side of the jointer closed-pipe housing 215. The jointer module 201 can provide a 90° elbow joint in a utility or structural support assembly, or it can provide a T-junction in a utility or structural support assembly.

[0095] An example of a five-way closed-pipe jointer hub assembly 210 is shown in Figures 6B and 7, comprising a jointer closed-pipe housing 215 having a jointer receptacle 211 at one end and a male component 70 at the other end, with three male member lateral mounting assemblies 110 extending radially outward from the jointer closed-pipe housing 215. The jointer receptacle 211 comprises a jointer receptacle assembly 220, which is secured by four screws 23 to four threaded pipe end thread slots 218 within the jointer closed-pipe housing 215. The jointer receptacle assembly 220 comprises a locking spring jointer half socket 221 and an unlocking jointer half socket 222 which work together to define (i) an outer bush channel 224 for an outer bush 26, (ii) an inner bush channel 228 for an inner bush 30, and (iii) a square nut slot 234 for securing a square nut 36 within the jointer closed tube housing 215 so as to align with either a retaining lock 50 or a lateral mounting hole 238.

[0096] The five-way closed-pipe jointer hub assembly 210 shown in Figures 6B and 7 can have a module length of two units corresponding to a diameter of two units of 60 mm, which is a typical system format sizing in 30 mm units, referred to herein as a unit scale. It should be noted that this is shown for illustrative purposes only and is not intended to limit the disclosure herein to these values ​​or proportions.

[0097] As disclosed herein, a male component 70 of another module of the system assembly can be detachably engaged with the joiner receptacle 211 of the joiner module by operating retaining lock half 52, 54 housed within the joiner receptacle assembly 220. When the male component 70 of another module (in this case, the second module) is inserted into the joiner receptacle 211 of the joiner module, the retaining lock chamfer 86 of the distal collar 87a of the male component 70 pushes back the retaining half lock 52 with spring receptacle, allowing the male component 70 to enter the joiner receptacle 211. The half-lock 52 remains pushed back until the distal collar 87a and four outer projections 82 of the male component 70 pass through the half-lock 52, the half-lock 52 aligns with the neck portion 88 of the male component 70, and the tension of the spring 56 causes the half-lock 52 to engage with the half-lock 54 with the release button at the neck portion 88. The operator can detach the second module from the joiner module by pushing the release button 55 through the release button hole 244 of the joiner closed pipe housing 215, thereby moving the retaining half-lock 54 with the release button inward, and moving the retaining half-lock 52 with the spring receptacle outward against the spring 56 until the retaining half-lock 52 with the spring receptacle 52 disengages from the neck portion 88 of the second module, allowing the second module to be removed from the joiner module.

[0098] The tension that the half-lock 52, with its spring 56, applies to the neck portion 88 of the male component 70 can be adjusted using the retaining lock set screw 40. The position of the set screw 40 relative to the half-lock 52 can be adjusted and secured using a tension adjustment screw knob 58 (shown in Figure 1) or other type of screwdriver via a retaining lock set screw hole (not visible in Figures 6 and 7) provided in the jointer closed-tube housing 215, in a square nut 36 housed in a square nut slot 234 provided in the lock spring jointer half socket 221. The retaining lock set screw 40 can be adjusted between a retracted position and an engaged position to bring about a range of pressures in the contact between the retaining lock half 52 and the neck portion 88 of the second module. The position of the set screw 40 when fully engaged prevents the movement of the retaining lock 50, thereby preventing the male component 70 of the second module from being removed from the joint receptacle 211, and preventing the second module from being detached until the half-lock 52 can be pushed back against the spring 56.

[0099] Unlike the rotator receptacle 11 shown in Figures 1 and 2, which provides a secure engagement with the second module of the rotator module, allowing the male component assembly of the second module to be rotated 360° within the rotator receptacle 11, the joiner receptacle 211 of the joiner module provides a firmly fixed, non-rotatable engagement for the male component assembly of the second module to be attached to the joiner receptacle 211. An example of the joiner receptacle 211 shown in Figures 6 and 7 comprises a joiner receptacle assembly 220 having two half sockets 221, 222 that form a total of four projection retention slots 223, so that when the male component 70 of another module is inserted, the eight projections 82 of the male component 70 align with the projection retention slots 223 and are firmly secured. Furthermore, the jointer receptacle assembly 220 further comprises an outer bush 26 and an inner bush 30 housed in bush channels 224 and 228, respectively, the outer bush 26 and the inner bush 30 cooperating with the projection retaining slot 223 when the male member assembly is inserted into the jointer receptacle 211, and engaging with the male member assembly by the wide pivot segment / component and the narrow pivot segment 84 of the male member assembly, respectively.

[0100] The five-way closed-tube jointer hub assembly 210, which provides five detachable engagement points with up to five other modular components, includes a jointer receptacle 211 in a jointer closed-tube housing 215, a male component 70 linearly aligned with the jointer receptacle 211, and a three-male member lateral mounting assembly 110 extending radially outward from the jointer closed-tube housing 215. The male component 70 linearly aligned with the receptacle is attached to the jointer closed-tube housing 215 in its octagonal recess 81 by connector screws 90 at the octagonal boss of the wide pivot segment of the housing (the octagonal boss and wide pivot segment are not visible in Figures 6B and 7). Each of the three male component lateral mounting assemblies 110 engages with the jointer closed-tube housing 215 by a bolt 120 that passes through the center of the male component 70, the wide pivot component 116, and the pivot lock sprocket 112, then through the lateral mounting hole 238 of the jointer closed-tube housing 215, and screws into a square nut 36 fixed to one of the outer square nut slots 234 of the jointer half sockets 221, 222.

[0101] The jointer closed-tube housing 215 may have eight lateral mounting holes 238 arranged at 45° intervals around the housing. These holes 238 provide varying degrees of angular orientation and spacing for mounting up to four male member lateral mounting assemblies 110 in various closed-tube jointer hub assemblies. Six of the eight lateral mounting holes 238 correspond to six square nuts 36 housed in square nut slots 234. The remaining two lateral mounting holes 238 are located adjacent to the joints of two jointer half sockets 221, 222 and require threaded inserts within the walls of the jointer closed-tube housing 215 due to the recesses of the half sockets that align with the square nut channels of the extension tube housing in extension tube jointer module configurations such as the double-sided receptacle extension tube jointer module 460 or the male / receptacle extension tube jointer module 465 shown in Figure 17.

[0102] Some embodiments disclosed herein relate to one or more of a group of lateral opening jointer modules for use in configuring utility or structural support system assemblies that may require an open-face or closed-type lateral connection that can detachably engage a male member assembly of a second module from the side of the jointer module. An example of a male / receptacle lateral opening jointer module 251 is shown in Figures 8A and 8B, and has a lateral opening receptacle 252 that can firmly or detachably engage a male component 70 / male member assembly of a second module.

[0103] The male / receptacle lateral opening jointer module 251 comprises an extension pipe housing 255 to which a lateral opening receptacle component 260 is fixed at one end by two screws 23 that screw into pipe end thread slots 257, and a male member extension pipe end assembly 270 fixed at the other end by four screws 23 that pass through threaded holes 278 provided in the male member pipe end plate 271 and screw into four pipe end thread slots 257 of the extension pipe housing 255. Pipe rail channels in the insertion portions of both the lateral opening receptacle component 260 and the male member pipe end plate 271 allow each component to be fixed between the inward-facing edges of back-to-back square nut channels 256 of the extension pipe housing 255.

[0104] A male lateral mounting assembly 110 for the second module is shown in Figure 8B (the second module is not shown) aligned for insertion into and secure engagement with the lateral opening receptacle 252. To facilitate insertion and removal of the male assembly of the second module into the lateral opening receptacle component 260 and to enable secure engagement with the lateral opening receptacle component 260, projection retaining slots 262 are provided within the lateral opening receptacle component 260, corresponding to the shape and alignment of projections 82 on the male component 70 of the male assembly to be inserted. For secure engagement of the cooperating modules, a lateral connector screw 265 can be inserted through holes provided in both the extension tube housing 255 and the lateral opening receptacle component 260 (these holes are not visible in Figure 8B) and screwed into one of the screw holes 89 in the neck portion 88 of the male component 70. If necessary, the lateral opening receptacle cover 268 can be further engaged with the receptacle component 260 to provide a protective cover for the engaged male member assembly. If separation of the lateral opening jointer module and the second module is required during use and / or operation of the system assembly, the lateral connector screw 265 and the lateral opening receptacle cover 268 can be removed from the assembly, and the male member assembly of the second module can remain in place temporarily until it is lifted from the receptacle or the open receptacle is turned downward.

[0105] The male member extension tube end assembly 270, located at the opposite end of the male / receptacle transverse opening jointer module 251 in this example shown in Figures 8A and 8B, comprises a male component 70 attached to a male member tube end plate 271, which has a wide pivot segment 274 and a pivot lock sprocket 272 for detachable engagement with other modules of the system assembly. The male member tube end plate 271 is secured to the extension tube housing 255 by four screws 23 that screw through threaded holes 278 into threaded slots 257 provided in the extension tube housing 255.

[0106] The outer end face of the male member pipe end plate 271 may be provided with a slot that aligns with the square nut channel 256 of the extension pipe housing 255, so that in the completed module, the square nut 36 can be inserted through the end face of the pipe end plate 271 into the square nut channel for detachable engagement with the male member lateral mount assembly 110.

[0107] In this example, up to four male member lateral mounting assemblies 110 can be mounted radially from the extension tube housing 255 by bolts that screw through one of the six lateral mounting holes 258 onto the square nuts 36, which are securely held within the tube housing by an intermediate square nut holder 180 having six square nut slots that align and position each square nut 36 in a lateral mounting hole 258. The intermediate square nut holder 180 is positioned inside the extension tube housing 255 during module assembly, as shown in Figure 8B, by positioning the inward-facing rail of the housing's square nut channel 256 within the tube rail channel 182. The square nut channel 256 not only provides an inward-facing rail but also a channel through which one or more square nuts 36 can slide, providing a threading point for the square nuts 36 to attach the male member lateral mounting assembly 110 to a position along the extension tube housing 255 selected by the operator, thereby enabling a wide variety of specific hub assembly configurations.

[0108] In some embodiments, the length of the extension tube housing 255 can be selected from a range of 2 cm to 240 cm, such as 2 cm, 4 cm, 5 cm, 6 cm, 8 cm, 10 cm, 15 cm, 20 cm, 25 cm, 30 cm, 35 cm, 40 cm, 45 cm, 50 cm, 55 cm, 60 cm, 65 cm, 70 cm, 75 cm, 80 cm, 85 cm, 90 cm, 95 cm, 100 cm, 110 cm, 120 cm, 130 cm, 140 cm, 150 cm, 160 cm, 170 cm, 180 cm, 190 cm, 200 cm, 210 cm, 220 cm, 230 cm, 240 cm, and in between. In the structure of a lateral opening jointer module having an extension tube housing with a length of 4 cm or more, it may be desirable to insert one or more intermediate square nut holders 180 within the length of the extension tube housing 255. Optionally, when assembling longer lateral opening jointer modules, the intermediate square nut holder 180 can be moved and held in place, and then temporarily engaged with an alignment thread rod in a threaded hole 184 to align and secure it in a selected set of lateral mounting holes 258. To prevent undesirable movement of the intermediate square nut holder 180, once in position, a short positioning set screw 186 can be inserted into an available lateral mounting hole 258 when the lateral mounting assembly 110 is not engaged. The intermediate square nut holder may include crush ribs on its outer edge to prevent undesirable movement within the extension tube housing.

[0109] Another embodiment of the present disclosure relates to a double-male jointer module having two male ends for detachably engaging with a receptacle of another module of a utility or structural support system.

[0110] An example of a double-sided male jointer module 281 used to detachably engage two adjacent receptacles of two modules of a utility or structural support system as needed is shown in Figures 9A and 9B. The double-sided male jointer module 281 comprises a double-sided male component 282 having a pivot lock sprocket 284 and a wide pivot segment 286 on both sides, the wide pivot segment 286 having an outward-facing octagonal boss 288 through which a threaded hole passes. Note that the proximal end of the male component 70 has an octagonal recess 81 configured to slide-engage with the octagonal boss 288. Each male component 70 is mounted onto the octagonal boss 288 and then secured to the double-sided male component 282 by inserting a connector screw 90 through the male component 70 and screwing it into the threaded hole provided in the octagonal boss.

[0111] Another embodiment relates to a double-sided male jointer module with an extension tube housing interposed between two male end assemblies. An example of a double-sided male extension tube jointer module 291 is shown in Figures 10A and 10B, and includes an extension tube housing 295 that engages with a male member extension tube end assembly 270 at each end.

[0112] The extension tube housing 295 has a pair of longitudinally extending, oppositely oriented square nut channels 296 and four equally spaced longitudinal threaded slots 297 extending between the ends of the extension tube housing 295. One or more intermediate square nut holders 180 can be inserted into the extension tube housing 295, and the tube rail channels 182 of the intermediate square nut holders 180 can slide along the inward-facing surfaces of the pair of longitudinally extending square nut channels 296 of the extension tube housing 295. In this example, up to six square nuts 36 can be inserted into the same number of slots of the intermediate square nut holders 180, and up to four male member transverse mounting assemblies 110 can be detachably engaged via transverse mounting holes 298. Positioning set screws 186 can be used to maintain the position of the intermediate square nut holders 180 even when the male member transverse mounting assemblies 110 are not engaged. For this purpose, the intermediate square nut holder 180 may be equipped with crush ribs around its outer edge for gripping the inner surface of the extension tube housing 295. By mounting the male member lateral mount assembly 110 at various positions along the extension tube housing 295 within the square nut channel 296, a range of specific hub assemblies can also be enabled.

[0113] The double-sided male extension tube jointer module has a male member extension tube end assembly 270, which is fixed to each end of the extension tube housing 295 by screws 23 that extend through threaded holes 278 in the male member tube end plate 271 and screw into tube end threaded slots 297 in the inner wall of the extension tube housing 295. An octagonal boss 275 slides into an octagonal recess at the proximal end of each male component 70, after which a connector screw 90 is inserted through the distal end of the male component 70 and screwed into a threaded hole provided in the octagonal boss 275.

[0114] Another example of a multi-engagement-point joiner hub assembly of the present disclosure is shown in Figures 11A and 11B. The six-way extension tube joiner hub assembly 301 may comprise a double-sided male extension tube joiner module 291 shown in Figures 10A and 10B, to which four male member transverse mounting assemblies 110 extending outward from the extension tube housing 295 are attached. The two oppositely oriented male member transverse mounting assemblies 110 are attached to the extension tube housing 295 by screwing bolts 120, which are inserted through the male member transverse mounting assemblies 110, into square nuts 36 inserted into square nut channels 296. The remaining two oppositely oriented male member lateral mounting assemblies 110 are inserted through the male member lateral mounting assemblies 110 and then attached to the extension tube housing 295 by screwing bolts 120, which pass through the lateral mounting holes 298, into square nuts 36 housed in intermediate square nut holders 180 (not visible in Figures 11A and 11B) located inside the extension tube housing 295.

[0115] Another embodiment of the present disclosure relates to a cross-format double-sided male adapter jointer module for facilitating engagement to a single utility or structural support assembly for modules having male assemblies and receptacles having different dimensions and optionally different system format characteristics such as the number of projections on the male ends. An example of a double-sided male adapter jointer module 311 is shown in Figures 12A and 12B.

[0116] The double-sided male adapter jointer module 311 comprises (i) a male member pipe end plate 271 to which a male component 70 is attached, the male component 70 being attached to the male member pipe end plate 271 by connector screws 90 which are inserted through the distal end of the male component 70 and screwed into threaded holes provided in the octagonal boss 275 of the male member pipe end plate 271. The double-sided male adapter jointer module 311 further comprises (ii) an adapter jointer component 312, the adapter jointer component 312 having (iii) another male member component 314 which differs from the male component 70 in diameter, length and number of protrusions for detachable engagement to receptacles of different system formats. The male member pipe end plate 271 is secured to the adapter jointer component 312 by inserting screws 23 into threaded holes 278 and screwing them into threaded slots 316 of the adapter jointer component 312.

[0117] Male component mounting module Further embodiments of the present disclosure relate to various male member mounting modules, which may include male member lateral mounting bracket modules and male member mounting block modules. In particular, the male member lateral mounting bracket module provides, among other functions, a unique hub assembly that may be included in a system assembly to detachably and fixedly or rotatably / slidably engage a mounted male member assembly onto an elongated tubular support element in a specific angular direction, allowing for rapid repositioning without requiring the removal of the mounted module. On the other hand, the male member mounting block module provides a variety of all-male hub assemblies.

[0118] Figure 13A shows an example of a two-way 30° lateral mounting bracket module 320 that can be detachably engaged with an elongated tubular support element such as an extension pipe housing. The 30° lateral mounting bracket module 320 comprises a 30° angled male member mounting bracket 322 and a clamp bracket 328. These can be securely engaged with an elongated tubular support element (not shown) by positioning the male member mounting bracket 322 and clamp bracket 328 around the elongated tubular support element, inserting clamp bracket screws 329 through holes in the clamp bracket 328, and screwing these screws 329 into holes in the 30° angled male member mounting bracket 322. Note that the combination of the male member mounting bracket 322 and the clamp bracket 328 can be called a "collar clamp". The 30° angled male member mounting bracket 322 has a pair of screw holes (not visible in Figure 13A) for engaging up to two male member lateral mounting assemblies 110, each extending outward at a 30° angle from the center of the module, or at a 60° angle (326) between the pair. The 30° angled male member mounting bracket 322 may have one or more mounting screw holes 323 to enable engagement of the 30° lateral mounting bracket module 320 to an elongated tubular support element by mounting screws 325 that screw into, for example, a square nut channel of an extension tube housing or a square nut housed in an intermediate square nut holder 180.

[0119] An example of a four-way multi-angle lateral mounting bracket module 330 is shown in Figure 13B, comprising a pair of opposing multi-angle male member mounting brackets 335 that surround and fasten to an elongated tubular support element such as an extension tube housing, each bracket 335 having a pair of opposing bracket screw holes 336 at each end of the bracket 335 for receiving bracket screws 338 and screwing them into corresponding holes in the opposing bracket. To engage the bracket 335 with the elongated tubular support element, at least one mounting screw hole 331 for receiving mounting screws 332 is provided along the center point of the longitudinal axis of each bracket 335 (three holes 331 are shown in Figure 13B), and a washer 339 is provided on the opposite side. Each multi-angle male member mounting bracket 335 has two opposing sets of three spaced-apart screw holes 334 that screw into bolts 120 to detachably fasten two outward-extending male member lateral mounting assemblies 110. Each of the three spaced-apart screw holes 334 allows the male member lateral mount assembly 110 to be mounted at an angle of 30°, 45°, or 60° from the center of the module, or allows the angle between pairs of male member lateral mount assemblies 110 mounted to the bracket 335 to be 60°, 90°, or 120°. In this example, the two 45° holes 334 provide mounting positions at an extension of, for example, 30 mm from the inner mounting circumference of the bracket 335.

[0120] A single multi-angle male member mounting bracket 335 can be used independently when attached to an extension pipe housing using one or more mounting screws 332, or when used as a standalone special angle hub.

[0121] An example of a bidirectional 90° offset lateral mount bracket module 340 is shown in Figure 13C, which includes a 90° angle offset male member mount bracket 341, the mount bracket 341 having mounting screw holes 342 accessible by mounting screws 325 and a screwdriver (not shown) via a screw access opening 346, so that the mount bracket 341 can be secured to an elongated tubular support element such as an extension tube housing (not shown) by mounting screws 325. This example of the 90° offset lateral mount bracket module 340 is fitted with two longitudinally extending, oppositely oriented male member lateral mount assemblies 110, which are positioned parallel to an elongated tubular support element to which the lateral mount bracket module 340 can be detachably engaged. Note that a combination of any of the male member mount brackets 322, 341, 335, etc., and any of the clamp brackets 328, 335, etc., or a plate wedge 445, etc., can be referred to as a "collar clamp".

[0122] An example of a 1-way 45° offset lateral mounting bracket module is shown in Figure 13D, and comprises a cylindrical 45° offset male member mounting bracket 351 that detachably engages with an example of a male member flat mounting assembly, which may be provided in a system assembly as disclosed herein, to enable detachable engagement of the male member to a flat surface. The male member flat mounting assembly 361 comprises a male member 70 (connected by bolts 120) as described above, attached to another example of a wide pivot component 367 that engages at the other end with another example of a pivot lock sprocket 362 for reversible fastening to a pivot lock 60 which engages with a flat surface, as described in more detail later.

Each end face of the mounting block 370 has four peg holes 372 for positioning and engaging the pivot lock sprocket 362 of the male member flat mount assembly 361. The male member flat mount assembly 361 engages with the end faces of the mounting block 370 by bolts 120 that are inserted through holes in the assembly 361 and screwed into a central hole 371 provided on the end face of the mounting block 370. According to a further embodiment, the angle between the end faces of the two-way elbow male member mounting block may be an angle other than 90°.

[0125] An example of a cubic male member mounting block module 356 is shown in Figure 14B. The 6-way cubic male member mounting block 373 has six symmetrical outward-facing faces for engaging with up to six male member flat mount assemblies 361 (two male member flat mount assemblies 361 are shown in Figure 14B). Each outward-facing face of the mounting block 373 has four peg holes 375 for receiving and engaging the pegs 365 of the pivot lock sprocket 362 and a central threaded hole 374 for screwing in a bolt 120 to securely mount the male member flat mount assembly 361.

[0126] An example of a triangular male member mounting block module 357 is shown in Figure 14C, which comprises a five-way triangular mounting block 376 having five faces for detachably engaging with up to five male member flat mount assemblies 361 (two male member flat mount assemblies are shown in Figure 14C). Each face of the triangular mounting block 376 has four peg holes and a central threaded hole for receiving and engaging with the male member flat mount assembly 361.

[0127] An example of a pyramidal male member mounting block module 358 is shown in Figure 14D, comprising a four-directional pyramidal mounting block 377 having four symmetrical outward-facing faces, each of which is configured to detachably engage with a male member flat mount assembly 361, as described for the cubic male member mounting block module 356 shown in Figure 14B. The pyramidal male member mounting block module 358 is shown in Figure 14D detachably engaged with two male / receptacle lateral opening jointer modules 251 (shown in Figure 8), and two additional male / receptacle lateral opening jointer modules 251 are shown in an exploded view aligned for detachable engagement, along with two corresponding male member flat mount assemblies 361.

[0128] An example of a hexagonal male member mounting block module 359 is shown in Figure 14E, comprising an eight-directional hexagonal mounting block 378 having six sides, a top surface and a bottom surface, configured to detachably engage with up to six male member flat mount assemblies 361, each side configured to detachably engage with one male member flat mount assembly 361 by a bolt that passes through a central hole in the assembly 361 and screws into a central hole in the mounting surface of the mounting block 378.

[0129] An example of an octagonal male member mounting block module 360 ​​is shown in Figure 14F, which comprises a 10-directional octagonal mounting block 379 having eight sides, a top surface and a bottom surface, configured to detachably engage with up to eight male member flat mount assemblies 361, each side configured to detachably engage with one male member flat mount assembly 361.

[0130] An example of a male member mount module 380 adjustable in 5° increments is shown in Figures 15A and 15B, comprising a male mount half housing 381 and a rotation adjustment half housing 386 into which a male member assembly detachably engages. The inward end faces of the male mount half housing 381 and the rotation adjustment half housing 386 are provided with interlocking teeth 388 that allow the rotation adjustment half housing 386 to engage with the male mount half housing 381 in a position adjustable manner in 5° increments. Thus, the angular distance between two lower male member flat mount assemblies 361, shown disassembled from brackets 390a and 390b in Figure 15B, can be adjusted and set in precise 5° increments. The two lower male member flat mount assemblies 361 are attached to brackets 390a and 390b in peg holes 394 by connector bolts 120 that screw into central holes 393. The brackets 390a and 390b are attached to the male mount half housing 381 and the rotation adjustment half housing 386 by screws 391 that thread through holes 392 into mounting holes 389 (visible only in the rotation adjustment half housing 386 in Figure 15B) prior to engagement with the flat mount assembly 361. The respective male member flat mount assemblies 361 can then be mounted. The adjustment screws 385 are then passed through holes 383 in the male mount half housing 381 and screwed into threaded holes 387 at the inward end of the rotation adjustment half housing 386. Optionally, additional flat mount assemblies 361 can be mounted on the outer surface of the male mount half housing 381 through peg holes 384 and through holes 383, but this requires longer versions of the adjustment screws 385 than when the additional flat mount assemblies 361 are not included in the assembly. At this stage, an adjustable hub assembly is created, and by loosening the adjustment screw 385, the teeth 388 of the housings 381, 386 can be disengaged and the relative position of the housings can be rotated, and then by tightening the adjustment screw 385 again, they can be re-engaged in one of 5° increments.As described above, the angular distance between the two male assemblies 361 attached to brackets 390a and 390b can be set in 5° increments from a maximum of 180° to a minimum of 60° where the two brackets will come into contact.

[0131] As shown in Figure 15, an optional male member flat mount assembly 361 can be attached to the outer surface of the rotation adjustment half housing 386 by bolts 120 that screw into the outer part of the central hole 387. In addition, two other examples of male member lateral mount assemblies as disclosed herein are optionally shown attached to the lateral mount hole 382 on the outer circumference of the male mount half housing 381. According to some embodiments, a male member lateral mount assembly 395 comprises the aforementioned male component 70 attached to a wide pivot component 367, the wide pivot component 367 being attached to another example of a pivot lock sprocket 396 having a wide pivot component slot 399 into which the component 367 can be engaged, in which case the assembly 395 can be detachably engaged to the lateral mount hole 382 or other module by bolts 120 that pass through the outer components 70, 367, through the central hole 397 of the pivot lock sprocket 396, and screw into the lateral mount hole. As shown in Figure 15, the lateral mount assembly 395 can provide a variety of adjustable hub assemblies, but in their use, it should be noted that the adjustable range of the angle setting of the male member mount module 380, which is adjustable in 5° increments, is limited to the point from where the bracket 390b on the rotation adjustment half housing 386 contacts the bracket 390a to where it contacts the nearest male member lateral mount assembly 395 on the male mount half housing 381.

[0132] Tool support module and load support module: Base plate module Some embodiments of this disclosure relate to base plate assemblies incorporated into a utility support system to enable detachable engagement of tools such as cameras, microphones, or sound equipment, as well as other types of tools, to the utility support system. For example, the base plate assemblies disclosed herein may be for mounting camera mount plates and camera accessories such as matte box holders and focus retraction devices. The base plate assemblies may include screw mounts or clips or dovetail plates or boxes or trays or baskets, etc., for detachable engagement of various tools and luggage.

[0133] An example of a base plate assembly 400 suitable for detachable engagement with a film camera, high-resolution video camera, DSLR, other device, or additional interface mounting plate or dovetail plate is shown in Figures 16A and 16B (perspective view and exploded perspective view, respectively). This example of a base plate module 400 comprises a base plate body assembly 402 having a base plate upper plate 402a fixed to a base plate bottom plate 402b by base plate screws 406. One or more mounting screws 404 (of any size as required) are provided through slots in the base plate body assembly 402 so as to screw into one or more mounting holes provided in the bottom of the camera or other device or mounted component.

[0134] In this example, the upper plate 402a and bottom plate 402b of the base plate cooperate to define three mounting bracket slots 408 that allow one to three offset and cooperating mounting brackets 410 to be fixed to the main body assembly 402 in selected positions for engaging and supporting cameras of various sizes and other suitable loads. Each mounting bracket 410 comprises (i) a bracket arm 412 configured to slidably engage with a mounting bracket slot 408 of the base plate main body assembly 402, (ii) a bracket side plate 415 that engages with the bracket arm 412 and extends upward from the bracket arm 412, and (iii) a male member plate assembly 420 that detachably engages with the outward-facing surface of the bracket side plate 415.

[0135] The male component plate assembly 420 comprises a male component 70 engaged with the mounting plate 422, the mounting plate 422 having an outward-facing wide pivot segment 424, an octagonal boss 425, a pivot lock sprocket 423, and a flat inward-facing plate surface, the flat inward-facing plate surface can be detachably engaged with the outward-facing surface of the bracket side plate 415 at a selected position by a screw 428 that is inserted through a screw hole 426 of the mounting plate 422 and screwed into a screw hole 416 provided in the bracket side plate 415.

[0136] An inward-facing support plate 417, to which a support pad 418 is fixed, is attached to the inward-facing surface of the bracket side plate 415 with screws 419. The support pad 418 can be positioned directly on a camera or other load, as can be positioned as described in more detail later, to supplement or replace the mounting screws 404 in securing the camera or other load.

[0137] The bracket arm 412 has a plurality of screw holes 413 arranged at equal intervals along the longitudinal axis of the arm 412. The selection of screw holes 413 is adjusted by the operator to correspond to the holes 405 in the base plate bottom plate 402b for screwing with base plate screws 406 inserted through the holes 405. The distance of safe outward extension of the bracket arm 412 can be adjusted in this example by selecting screw holes 413 that are spaced apart to screw with the base plate screws 406 inserted through the holes 405, so as to produce system format unit scale widths of various sizes for the overall width between the opposing male member plate assemblies 420 of the module assembly 400.

[0138] It should be noted that the male member plate assembly 420 shown in this example can be detachably engaged with the receptacle components of the rotator module or rotator assembly disclosed herein, or the receptacle components of the joiner module or joiner assembly disclosed herein, or other assemblies as disclosed herein having receptacle components. It should be noted that in this example, the offset of the centers of the bracket side plates 415 from the center of the bracket arm 412 can align the two opposing side plates 415 and the mounted male member plate assembly 420 when adjacent mounting bracket slots 408 are used, resulting in only one axis between the oppositely oriented male member plate assemblies 420. As shown, the base plate assembly may further include a male member plate assembly 420 detachably engaged with the underside of the base plate body assembly 402 to provide an additional axis for pivotable or fixed engagement of the base plate assembly 400 in the system assembly.

[0139] For example, another example of a base plate module suitable for detachable engagement with a camera is shown in Figures 17A and 17B (perspective view and exploded perspective view, respectively). This example of a base plate assembly 430 includes a tool mount plate 435 engaged with a double receptacle extension tube joiner module 460 sandwiched between two male / receptacle extension tube joiner modules 465. A pair of multi-angle male member mount brackets 335, as already described with respect to Figure 13B, are mounted side by side to the lower longitudinal portions of the double receptacle extension tube joiner modules 460 and engage with two sets of plate wedges 445 by four bracket screws 338 that are inserted through holes 447 in the plate wedges 445 and screwed into holes provided in the multi-angle brackets 335. In the opposite direction, the four bracket screws 338 can be inserted into holes 336 and screwed into holes on the underside of the plate wedges 445. When the bracket screw 338 is loosened, the engagement with the joiner module 460 is slidable or pivotable over a given length of the joiner module 460. For secure retention, the bracket screw 338 can be tightened. Optionally, the multi-angle bracket 335 can be directly engaged with the joiner module or rotator module by one or more mounting screws 332 that screw into square nuts 36 slidably engaged within the square nut channels of the corresponding module.

[0140] The tool mount plate 435 is fixed to the plate wedge 445 by screws 442 that are inserted through plate screw holes 440 and screwed into screw holes 446 of the plate wedge 445. For example, a camera mount plate that auxiliaryly attaches to a tool or other device such as a camera, or to a camera or camera accessories, can be fixed to the tool mount plate 435 by mounting screws 436 that are inserted through tool mounting slots 437 and screwed into one or more mounting holes provided on the bottom of the tool or device.

[0141] The male flat mount assembly 361 engages with the male mount slider component 450, which is inserted through a hole 336 in the multi-angle bracket 335 and screwed into a bracket screw hole 456 of the male mount slider component 450, and further inserted through an opposing hole 456 of the slider component 450 and screwed into a second pair of opposing holes 336 of the multi-angle bracket 335, thereby being fastened to the male / receptacle extension tube joiner module 465 by bracket screws 338. The positions of the slider component 450 and the multi-angle bracket 335, which are fastened together, on the joiner module 465 can be changed by loosening the bracket screws 338, selecting a new position, and then tightening the bracket screws 338 again.

[0142] The positions of the male mount slider component 450 and the multi-angle bracket 335, which are fastened together, along the male / receptacle extension tube joiner module 465 can be further fixed and adjusted as follows: A pair of square nuts 36 are inserted into each of the opposite longitudinal channels 466. Two mounting screws 332 are inserted through mounting holes 331 provided in the multi-angle bracket 335 and screwed into one pair of square nuts 36 (a pair of washers 339 are interposed between the inner surface of the multi-angle bracket 335 and the extension tube joiner module 465). Two mounting screws 453 are inserted through mounting holes 452 provided in the male mount slider component 450 and screwed into the other pair of square nuts 36 (a pair of washers 339 are interposed between the inner surface of the male mount slider component 450 and the extension tube joiner module 465). After loosening the mounting screws 453 and 332, the male mount slider component 450 and the multi-angle bracket 335, which are fastened together, can be slid along the male / receptacle extension tube joiner module 465 to the selected position, after which the screws 453 and 332 are tightened again. Optionally, only the pair of screws 453,332 may be used with just one square nut channel 466.

[0143] It should be noted that the base plate assembly or other module assemblies can use the male mount slider component 450 alone, or in combination with the multi-angle bracket 335, they can be fastened together in pairs in the same manner as described above. It should be noted that the male mount slider component 450, by its width, can provide an extension of, for example, 30 mm in unit scale from the outer circumference of the module to which it is mounted, with respect to its central male member mounting hole 454. In the example of the base plate assembly 430, this feature provides a unit scale width across the entire module.

[0144] A male member flat mount assembly 361, positioned by peg holes 455 and secured by bolts that screw into central holes 454, extends from a male mount slider component 450 toward the center of the base plate assembly 430, detachably engages with the receptacles at both ends of the double receptacle extension tube joiner module 460. In assemblies where the screws 332 and square nuts 36 are not engaged with the longitudinal channels on the underside of the joiner module 460, the supported tool mount plate 435 can be rotated to a desired position around the double receptacle extension tube joiner module 460 by slightly loosening the bracket screws 338 with a tool inserted through access holes 441 in the tool mount plate 435 and bracket screw holes 336 in the multi-angle bracket 335, then rotating the tool mount plate 435 to the desired position, and then re-engaging the bracket screws 338. Alternatively, for an open and intermittently fixable 360° pivotable connection of the tool mount plate 435 to the outer assembly, the joiner module 460 can be replaced with a bilateral receptacle rotator module such as the typical rotator module 151 shown in Figure 4.

[0145] The base plate assembly 430 can be reliably engaged within a larger utility or structural support assembly by one or both of the receptacles of the two jointer modules 465 or by one or both of the male member extension tube end assemblies 270 of the two jointer modules 465, or by adding a male member lateral mount assembly 110, 395 (not shown) to one of the jointer modules 465 or the multi-angle bracket 335.

[0146] Tray module Some embodiments of the present disclosure relate to tray modules that can be incorporated into utility system assemblies. An example of a tray module assembly 470 is shown in Figures 18A and 18B (perspective view and partially exploded perspective view, respectively), comprising a tray base 471 having orifices 472 at each corner. Note that the tray base may be rectangular, square, trapezoidal, triangular, pentagonal, hexagonal, heptagonal, or octagonal. An example of a square tray base 471 is shown having four orifices 472 at each corner for insertion and reversible engagement of extension tube joiner modules or extension tube rotator modules of various lengths, which can optionally function as structural corner supports for the system assembly. Adjacent to each orifice 472, the tray base 471 further comprises collar holes 473, to which a collar 474 is detachably secured to the tray base 471 by collar screws 476 passing through the collar holes 473 into threaded holes in the collar 474.

[0147] In this example of tray module 470, four second examples of double-sided receptacle extension tube joiner modules 475 (here longer than the joiner module 460 already shown in Figure 17) are provided, passing through four combined collars 474 and the tray bottom 471. The extension tube joiner modules 475 can be detachably secured to the center of each collar 474 by collar screws 476 that pass through lateral holes in the collar and screw into square nuts 36 located in longitudinal square nut channels 477, or screw into square nuts 36 housed in the receptacle socket assembly or intermediate square nut holder within the module's extension tube housing. The collars 474 may further have lateral screw holes, in which side panels 478 can be detachably secured by side panel screws 479 that pass through holes in the side panels 478 and screw into the collars 474. For additional reinforcement, the upper ends of the extension tube jointer module 475 and side panel 478 are optionally secured to four additional collars 474 as shown. In assemblies where the collars 474 engage along the square nut channels 477 of the corner module, the assembly of the collar bottom 471 and the side panel 478 can be raised or lowered on the corner module by loosening the collar screws 476, selecting a new position, and then tightening the collar screws again. Note that the tray bottom and tray sides disclosed herein may also be referred to as “flat sheet stock”.

[0148] Such tray modules can be incorporated into utility system assemblies for use in holding and transporting equipment, tools, materials, consumables, etc., at work sites or other locations, or for use in shelving systems or stage platforms. The tray modules can be pivotably engaged with the utility system assembly, and, if desired, attached to a rotator module to provide load damping functionality. Furthermore, the tray modules can be incorporated into platform assemblies, table assemblies, or workstation assemblies.

[0149] Table Module Some embodiments of this disclosure relate to table and desk and shelf module assemblies that can be assembled using some of the modules disclosed herein and can also be used to assemble a stage platform. An example of a desk assembly 480 is shown in Figure 19A, comprising a desktop 481 with an example of a double-sided receptacle lateral opening jointer module 488 engaged at each corner. Note that the desktop or tabletop may be rectangular or square or trapezoidal or triangular or pentagonal or hexagonal or heptagonal or octagonal or circular or elliptical. Shelves 482 may be provided as needed, by engaging a pair of second examples of double-sided receptacle lateral opening jointer modules 489 attached to the desktop 481, for example. An example of how the double-sided receptacle lateral opening jointer modules 488 are engaged with the desktop 481 is shown in Figure 19B. Although not visible in Figure 19B, recesses identical to the recesses 483 on the top surface of the desktop 481 are provided on the bottom surface of the desktop 481 at each corner. A mounting plate 484 having a central screw hole 485 is inserted into the recess and securely attached to the desktop 481 by five screws 487 inserted, for example, through holes 486 provided in the mounting plate 484. Note that the mounting plate may be circular, elliptical, triangular, square, rectangular, trapezoidal, hexagonal, or octagonal, and various numbers of screw holes 486 can be provided.

[0150] The male flat mount assembly 361 is attached to the plate 484 by mounting bolts that screw into the threaded holes 485. The male flat mount assembly 361 is then inserted into the end receptacle of the double receptacle transverse opening jointer module 488 and secured in place as described for the transverse opening jointer module 251 with reference to Figure 8B. Alternatively, one or more rotator modules, or one or more jointer modules such as the double receptacle extension tube jointer module 460 described with reference to Figure 17B, can be attached. If a shelf 482 is added, the plate 484 is inserted into a recess 483 provided on the top surface of the desk and secured in place by screws 487 inserted through holes 486. The male flat mount assembly 361 is attached to the plate 484 by mounting bolts that screw into the threaded holes 485, and then the male flat mount assembly 361 is inserted into the receptacle at the end of the double-sided receptacle lateral opening jointer module 489, or into the receptacle of another double-sided receptacle module. A pair of plates 484 and male flat mount assemblies 361 are attached to the bottom of the shelf 482 and secured to the receptacle at the other end of the double-sided receptacle lateral opening jointer module 489 as shown in the figure.

[0151] Lighting mounting module Several embodiments of a lighting mount module that provides mounting means for detachably engaging a lighting fixture or other similar fixture to several utility system assemblies are shown in Figures 20A to 20D. An example of a lighting mount module 490 is shown in Figures 20A and 20B, and comprises an extension tube housing 492 having a male member extension tube end assembly 270 fixed at one end. A spigot 498 is screwed into a spigot mounting plate 494 by a screw 497 inserted through a threaded hole 496 in the spigot mounting plate 494. The spigot assembly is then attached to the other end of the extension tube housing 492 by a screw that screws into a threaded hole provided in the extension tube housing 492.

[0152] Another example of the lighting mount module 500 is shown in Figures 20C and 20D, which comprises a spigot adapter male component 501 having a wide pivot segment 507 at one end, and a male component 70 is attached by a screw 90 that screws into a hole in the octagonal boss of the wide pivot segment 507. The spigot adapter male component 501 has a pivot lock sprocket 506 located around its midpoint and a spigot receptacle 503 located at the other end. A spigot 502 is inserted into the spigot receptacle 503 and secured in place by a set screw 504 that is inserted through a screw hole 505 and tightened by a tension adjustment screw knob 58 or other screwdriver.

[0153] Base module: Rail rolling module Some embodiments of this disclosure relate to rail-rolling modules and assemblies configured for detachable engagement of a video camera that can be moved along a rail-track system, for example in film production or video shooting. Similar assemblies can be used to transport other equipment, tools, fixtures, materials, belongings, etc., along a rail-track system at a work site or other location. Some examples of rail-rolling modules and assemblies are shown in Figures 21A, 21B, and 22.

[0154] An example of a rail rolling module 510 (Figures 21A and 22) includes two pairs of spring suspension roller assemblies 514 engaged with a carriage plate 512 and has an upward-extending male member plate assembly 420. Each roller assembly 514 includes an axle block 516 having a downward-extending end, the downward-extending end having a through hole for receiving an axle bolt 520. Washers, then rollers 518, another washer, and then a lock nut are positioned on each axle bolt 520, the lock nut rotatably securing the roller 518 to the axle block 516. One end of a spring block 522 is rotatably attached near one end of the axle block 516 by a suspension bolt 524. The other end of the spring block 522 has a recess for housing a spring tension plate 528 and a spring 530 biased against the other end of the axle block 516. The spring tension can be adjusted by tightening or loosening a spring tension set screw 526 provided on the spring block 522. A pair of spring suspension roller assemblies 514 are attached to both ends of the carriage plate 512 by screws (not shown) passing through holes in the spring block 522 into screw holes provided on the upper part of the carriage plate 512. Optionally, a spacer plate 532 can be attached to the approximate center of the carriage plate by screws (not shown), and a male member plate assembly 420 having a male component 70 engaged with a mounting plate 422 is attached to the upper surface of the spacer plate 532 to complete the rail rolling module 510. Optionally, if desired, a friction pad plate 540 having a rail-facing friction pad 542 can be additionally attached to the rail-facing surface of the carriage plate 512 to adjust the speed at which the rail rolling module 510 moves along the rail track system. The friction pad plate 540 is attached to the carriage plate 512 by a pair of tension adjustment knobs 544, each having a threaded portion that screws into a hole provided in the carriage plate 512 at the top.Around the unthreaded lower portion of each knob 544 (which passes partway through the unthreaded hole in the friction pad plate 540), an upper retaining ring 548 is provided, extending from top to bottom, held by the upper neck portion of the knob's shaft (adjacent to the lower part of the threaded portion), and a spring 546 is interposed between this ring and the plate 540. When the knob 544 is extended downward by rotation, the upper retaining ring 548 applies pressure to the spring against the plate 540, increasing the tension of the friction pad 542 against the rail (not shown). The remaining portion of the knob's shaft passes through the plate 540, and a second lower retaining ring 548, held by the lower neck portion of the shaft, prevents the plate 540 from separating from the knob 544.

[0155] Alternatively, if suspension of the module by spring load on the rail is not desired, the rail rolling module may have two fixed roller assemblies 535 (described in more detail later) instead of the two spring suspension roller assemblies 514.

[0156] An example of a rail-enclosed rolling module assembly 537 (Figures 21B and 22) includes a second carriage plate 512 attached to a rail-enclosed rolling module 510, using at least one side plate 538, and optionally two side plates 538 (each end of which is engaged with a fixed roller assembly 535). Each fixed roller assembly 535 includes an axle block 536 to which a pair of rollers 518 are attached, as described for the spring-suspended roller assembly 514. The two axle blocks 536 are attached to the second carriage plate 512 by screws (not shown), and the second carriage plate 512 is attached to one end of the side plate 538 by screws (not shown). The rail-enclosed rolling module assembly 537 is formed when the rail-enclosed rolling module 510 engages with the opposite end of the side plate 538. The rail-enclosed rolling module assembly 537 is particularly useful for safely and reliably transporting camera equipment, or other devices, tools, instruments, or supported loads along rail track systems that are not horizontally flat, including vertical or inclined rails and one or more curved rails. Optionally, the rail-enclosed rolling module assembly 537 can be modified by attaching a male member plate assembly 420 to a second spacer plate 532 and / or one or two side plates 538 for up to four outwardly extending male member assemblies provided for interconnecting the module assemblies in a structural support system. Optionally, if desired, one to four spacer plates 532 can be eliminated, and the male member plate assembly 420 can be directly engaged with the carriage plate 512 and side plates 538, thereby varying the width between opposing male member plate assemblies 420 and optionally allowing for module unit scale widths or other full widths.

[0157] Alternatively, a further rail-enclosed rolling module may comprise an assembly having four spring-suspended roller assemblies 514 or four fixed roller assemblies 535. Alternatively, a further rail-enclosed rolling module may comprise an assembly having one or two friction pad plates 540 and friction pads 542, or an assembly without friction pad plates 540 and friction pads 542. Furthermore, the rail-enclosed rolling module may be assembled in the opposite configuration to the assembly 537 which engages with two opposing rails, with the carriage plate 512 and roller assemblies 514 or 535 facing outward and detachably engaged with a male member plate assembly 420 that now faces inward.

[0158] Wheel module Other embodiments of the present disclosure relate to wheel modules that can provide transport or mobility functions in a utility system assembly. Various wheel modules and wheel module assemblies include steerable assemblies or open 360° pivotable caster assemblies or caster-type assemblies.

[0159] An example of a wheel module assembly 550 is shown in Figures 23A and 23B, which includes a wheel axle / receptacle lateral opening jointer module 555 into which a wheel 552 rotatably engages by an axle bolt 554. The lateral opening jointer module 555 includes an extension tube housing 255 having an opposite longitudinal square nut channel 256 and an internally housed intermediate square nut holder 180, a lateral opening receptacle component 260 having a lateral opening receptacle cover 268, and a wheel axle tube end component 551 that engages with mounting screws. The wheel axle tube end component 551 has a central threaded hole 551a and two offset threaded holes 551b. The axle bolt 554 can be screwed into either the central threaded hole 551a or one of the two offset threaded holes 551b, the offset holes 551b allowing the wheel module assembly to act as a caster.

[0160] Another example of a wheel module according to this disclosure is a caster wheel module assembly 560 shown in Figures 23C and 23D, in which a pivot or fixed caster wheel 568 is screwed into a hole provided in a mounting component 562. A male member flat mount assembly 361 engages with the mounting component 562 by positioning the peg of the pivot lock sprocket 362 in the peg hole 566 and screwing the bolt 120 into the threaded hole 564.

[0161] Foot module An example of a leveling foot module 580 is shown in Figures 24A and 24B (perspective and exploded perspective views, respectively), and includes a male flat mount assembly 361 that engages with the mount component 562 in the same manner as described for the caster assembly 560 with reference to Figure 23D. An adjustable foot component 581 has a foot end 583 from which a leveling threaded rod 582 extends, onto which a nut 584 is screwed. The adjustable foot component 581 is screwed into a hole in the mount component 562 until the nut 584 can be tightened against the bottom of the component. The stable extension distance of the foot end 583 from the mount component 562 can be adjusted by rotating the nut 584 along the leveling threaded rod 582 so that it moves closer to or away from the foot end 583 before screwing the leveling threaded rod 582 into the hole in the mount component 562.

[0162] An example of a footplate module 585 is shown in Figure 24C, which includes a footplate 586 having screw holes 587 around the center of the footplate 586, and a male member plate assembly 420 is attached to the footplate 586 by screwing screws 428, which are inserted through holes in a mounting plate 422, into the holes 587.

[0163] Pivotable support module An example of a pivotable support module 590 is shown in Figures 25A and 25C, which comprises a male member plate assembly 420 fixed to a pivot bracket 592. The male member plate assembly 420 is fixed to the pivot bracket 592 by mounting plate screws 428 that are inserted through holes in the mounting plate 422 and the pivot bracket 592 and screwed into lock nuts 593. A pivotable pad component 594 having oppositely oriented screw holes 595 is inserted into the pivot bracket 592 and fixed in the desired position by screwing a knob 598 into the screw holes 595 (Figures 25A and 25B). When rotatable adjustment of the position of the pad component 594 is desired, a washer 599 can be inserted beyond the threaded portion of the knob 598 before screwing the knob 598 into the screw holes 595, so that the knob can be easily loosened or tightened relative to the pad component 594. The pivotable support module 590 is shown rotatably engaged with the suction cup component 596 in Figure 25C for detachable engagement with glass or other smooth surfaces.

[0164] Weight module An example of a weight module assembly 600 is shown in Figures 26A and 26B, and includes a weight component 602 detachably engaged with another example of a double receptacle extension tube rotator module 605, which has an extension tube housing 606 having a pair of oppositely oriented longitudinal square nut channels 608 into which a plurality of square nuts 36 slidably engage, as described with reference to Figures 4 and 5 for double receptacle extension tube rotator modules 151 and 152. The inner surface of the first weight component 602 abuts against the extension tube housing 606, and a bolt 604 is inserted into an outer hole 603a provided in the weight component 602 and then screwed into a square nut 36 housed in the square nut channel 608. The second bolt 604 is inserted into another outer hole 603a provided in the first weight component 602 and then screwed into the second square nut 36 housed in the square nut channel 608. The second weight component 602 abuts against the extension tube housing 606 on the opposite side of the first weight component 602 and is screwed into the square nut 36 housed in the opposite square nut channel 608 by two bolts 604 inserted through the hole 603a of the second weight component 602. Alternatively, one or a pair of weight components 602 may be mounted by bolts 604 that screw through the central hole 603b into a square nut held by the module's receptacle assembly or intermediate square nut holder through the lateral mounting hole of the extension tube housing. If a heavier counterweight or base weight is desired in the weight module assembly 600, one or more additional weight components 602 can be similarly screwed into the extension tube housing 606.

[0165] Telescopic extension module A typical telescopic extension module 610 is shown in Figures 27A, 27B, and 27C (perspective view, exploded perspective view, and longitudinal section view, respectively), and generally comprises an extension pipe housing 612 having a male member pipe end plate 271 to which a male component 70 is attached. An extension assembly is attached to the other end of the extension pipe housing 612, which comprises a rod retaining component 614 that is attached to the end of the extension pipe housing 612 by four screws 23. A rod retaining plate 616 having a central hole for receiving a threaded rod 620 is attached by screws 619 to the inward surface of an adjustment collar component 618, whose inner portion passes through the center of the rod retaining component 614, while abutting the inward surface of the rod retaining component 614. The collar component 618 and plate 616 securely and rotatably clamp the rod retaining component 614, which secures the assembly within the extension pipe housing by screws 23. The adjustment collar component 618 has a threaded hole through which it screws onto the threaded rod 620. The distal end of the threaded rod 620 has a smaller diameter threaded portion 621 which is inserted through a hole in the spacer plate 622 and secured to the spacer plate 622 by screwing with a washer and a lock nut 624. The male member plate assembly 420 (see Figure 16B and related description) is inserted through a hole in the mounting plate 422 and attached to the spacer plate 622 by screws 428 which are screwed into threaded holes in the spacer plate 622.

[0166] The operator can extend the male member plate assembly 420 away from the extension tube housing 612 by rotating the adjustment collar component 618 clockwise, thereby advancing the threaded rod 620 and the mounted male member plate assembly 420 outward until the desired outward extension of the male member plate assembly 420 is achieved. The operator can retract the male member plate assembly 420 in the opposite direction by rotating the adjustment collar component 618 counterclockwise. Once the approximately desired rod projection length is achieved, the male member plate assembly 420 and the threaded rod 620 can be rotated a small amount in either direction, if necessary, to properly orient the mounted male component 70 and the corresponding receptacle module (not shown).

[0167] End cap module: The following examples of end cap modules shown in Figures 28 to 33 provide the functionality of various structural end components for applications such as hand grips or feet or bumpers or grounding pads or general protective covers for exposed male or receptacle assemblies of system assemblies.

[0168] An example of a grip end cap module 625 that can be optionally used as a handgrip, foot, or bumper is shown in Figures 28A to 28E, and comprises a handle grip component 626 and an outer sleeve 631 that rotatably cooperates with the handle grip component 626. The handle grip component 626 comprises a semicircular end cap portion 627 at one end, an elongated handgrip portion 628 in the middle, and an inner sleeve 629 at the other end. In this example, four projection-retaining slots 630 are provided in the form of recesses within the inner cavity of the handgrip portion 628, and can receive and secure a corresponding number of linear sets of projections of a male component 70 (not shown) of a cooperating module. When in the open position shown in Figure 28D, the male component assembly of the cooperating module, including the male component 70, can be inserted into the grip end cap module 625. Subsequently, by rotating the outer sleeve 631 to the closed position as shown in Figure 28E, the retaining tab 632 can be aligned with the projection retaining slot 630, and the projection 82 (for example, shown in Figures 1 and 2) can be secured within the projection retaining slot 630, thereby securing the male component 70.

[0169] Another example of an end cap module is the shell end cap module 635 shown in Figures 29A and 29B, which is attached to the male / receptacle extension tube rotator module 640. The shell end cap module 635 comprises a pair of matching half-shell caps 636, which are detachably engaged with the male component 70 of the male / receptacle extension tube rotator module 640 by screws 637 that are inserted through holes 638 provided in these half-shell caps and screwed into threaded holes 89 in the neck portion of the male component 70.

[0170] An example of a female dome pad end cap module 641 is shown in Figures 30A and 30B, and includes a female dome pad 642 having a collapsible framework 643 with a central orifice 645. The female dome mounting plate 646 is attached to the framework 643 by screws 648 that are inserted through holes 647 provided in the mounting plate 646 and screwed into threaded grooves or screw inserts provided in the framework 643. The female dome mounting plate 646 has an orifice 649 aligned with the orifice 645 of the framework 643. The orifices 649, 645 are sized to slidably and frictionally engage with a shell end cap module 635 (shown in Figure 29) engaged with a male / receptacle extension tube rotator module 640 or other modules.

[0171] An example of a male dome pad end cap module 650 is shown in Figures 30C and 30D, and comprises a male dome pad 652 having a collapsible framework 653. A male member flat mount assembly 361 is attached to a male dome mounting plate 654 by bolts through screw holes 656 and peg holes 657. The male dome mounting plate 654 is attached to the framework 653 by screws 648 that are inserted through holes 658 in the mounting plate 654 and screw into screw grooves or screw inserts provided in the framework 653, which can be collapsible.

[0172] Some embodiments of the modules disclosed herein include seat end cap modules that can be incorporated into utility system devices or stool or bench assemblies configured for a ride-on dolly mechanism. An example of a seat module 660 is shown in Figures 31A and 31B, which comprises a seat pad 662, and a male member plate assembly 420 is attached to the seat pad 662 by screws 428 that are inserted through holes in a mounting plate 422 and screwed into threaded holes (not visible in Figure 31) provided in the seat pad 662.

[0173] An example of the bumper end cap module 670 is shown in Figures 32A and 32B, mounted on a closed-tube rotator hub assembly 100 having a laterally extending male member lateral mount assembly 110 (first shown in Figure 3A). The bumper component 672 is fitted over the wide pivot segment 78 of the rotator hub assembly 100 and secured in place by screws 674 that are inserted through an orifice in the bumper component 672 and screwed into threaded holes in an octagonal boss 79 extending upward from the wide pivot segment 78.

[0174] Various further end cap components according to some embodiments of the present disclosure are shown in Figures 33A to 33F. An example of a flexible end cap component 680 is shown in Figures 33A to 33C, and comprises a flexible hemispherical dome component 688 with four inserts 686 having threaded holes. An elongated leg component 681 having a single mounting plate 682 with four holes 683 is attached to the dome component 688 by four screws 685 that are inserted through the four holes 683 and screwed into the four inserts 686 in the dome component 688. The flexible end cap component 680 can be engaged with a receptacle component of a closed-pipe rotator hub assembly 100, for example, as shown in Figure 33C. When used in a transverse-opening receptacle, the component 680 can be firmly engaged by screws that screw into threaded holes 689.

[0175] An example of a rigid end cap component 690 useful for covering and protecting unused receptacles in a rotator module or joiner module incorporated into any utility system assembly according to this disclosure is shown in Figures 33D and 33E. This example of a rigid end cap component 690 has a flat outward-facing surface 693 and an elongated downward-extending leg component 691, the surface 693 having a pull tab extending across the surface 693, and the leg component 691 having a radial retaining lock chamfer 692, the radial retaining lock chamfer 692 pressing back the half-lock until it passes a cooperating spring-received retaining half-lock 52 when the rigid end cap component 690 is inserted into the receptacle of the rotator receptacle assembly 20 or joiner receptacle assembly 220, thereby securing the rigid end cap component 690 in the receptacle until the retaining lock 50 is released. Figure 33E shows a rigid end cap component 690 engaged with the rotator receptacle assembly of the closed-pipe rotator hub assembly 100.

[0176] A simple flat end cap component 695, shown in Figure 33F, can be fixed to the open end of any type of extension tube housing disclosed herein. The flat end cap component 695 has four holes 696 on its outer circumference, through which a screw 23 can be inserted and screwed into a threaded slot 698 provided at one end of a typical extension tube housing 697, which engages at the other end with a male member extension tube end assembly 270.

[0177] Unit scale Typical modules disclosed herein can be constructed from various materials in a range of sizes to facilitate the assembly of utility systems and support structures for use in a variety of applications. For ease of use, as well as for the interoperability and compatibility of modules throughout the system, a module unit scale can be used in all modules of the system format. In the configuration of various embodiments, the unit scale can have various sizes depending on the intended use of the modular system. The sizes and proportions presented and illustrated are for illustrative purposes only to inform of the relative function and compatibility of interconnected modules, and are not intended to limit the modules of this disclosure to these values ​​or proportions.

[0178] According to some embodiments of the present disclosure, a suitable system format has a pipe module with a unit scale standard of 2 units in diameter, where 1 unit may be equal to, for example, 30 millimeters. Receptacles 11, 211 and complementary male member assemblies 71, 110, 270, 361, 395, 420 may be longer than 2 units, but closed pipe module 10 / 201 comprises a closed pipe housing 15 / 215 that provides a module unit scale length of 2 units, facilitating a hub assembly having a cubic module unit scale of 2 units × 2 units, where the receptacle assembly 20, 220 overlaps within the hollow center of the wide pivot segment of the closed pipe housing 15 / 215. According to some embodiments, typical rail rolling modules 510 and rail encircling rolling module assemblies 537 can each provide unit-scale configurations in up to two or four directions, with male member plate assemblies 420 mounted on cooperating sized spacer plates 532, which are coupled to the rail rolling modules 510 and 537, resulting in module widths of, for example, six units between the male member plate assemblies 420, and enabling parallel configuration with other modules of the same system format.

[0179] Using a unit scale across the entire module of the system format facilitates the calculation and configuration of the parts required to reach the final assembly. Furthermore, in the case of a series of extension tube modules that provide a length over which rail rolling modules 510, 537 can be moved, for example, the unit scale length can provide the operator with a visual guide of the distance to be moved by connection points or lateral mounting holes of the module that may be included along the length of the extension tube, and can also provide connection points for end cap modules that are positioned, for example, as stoppers, at desired positions along the extension tube module rail track assembly.

[0180] kit According to some embodiments disclosed herein, a group of one or more of the various types of modules disclosed herein can be provided together in a kit for assembling into a specific type of modular utility system assembly or support structure for various functional requirements. The kit of this disclosure may further include, or be packaged together with, equipment or tools for assisting in the assembly of the system, and / or printed or software instructions for the assembly of the system, regardless of the type or number of the final system assembly or modules.

[0181] Customizable assemblies The modular units of this disclosure can be interconnected to form a wide variety of utility system assemblies and support structure assemblies that may be designed for a wide variety of applications. In this way, the utility system or support structure can be customized to a specific application by using a selected combination of interconnection modules of a given system format, or by using adapter joiner modules 311 or other fastener modules of multiple system formats. The wide range of configurability allows the system to be assembled in a wide range of sizes and functional designs to meet the requirements of a wide range of end users. For example, the modules of this disclosure can be interconnected to form utility systems or support structures including, but not limited to, carts, dollies, tracks, cranes, lifts, stands, racks, tables, workstations, seats, bed frames, shelves, storage areas, stages, railings, partitions, toy systems, etc. Optionally, the system assemblies can be combined with third-party tools, mechanisms, and systems to meet the requirements of various end users.

[0182] In some embodiments, the modules disclosed herein can be selected and interconnected to assemble a number of customized tool / load support assemblies, which may be configured for use in applications such as filmmaking and / or videography and / or still photography, including, but not limited to, support systems for positioning and moving cameras, microphones, and lighting; and in other embodiments, they can be selected and interconnected as carts or stands for other equipment and possessions in various industrial or household applications.

[0183] To better understand the embodiments disclosed herein, the following examples of utility system assemblies and support structure assemblies are described. [Examples]

[0184] To further illustrate the versatility of the module in the assembly of various utility system assemblies and support assemblies such as carts, dollies, tracks, cranes, lifts, stands, racks, tables, workstations, seats, bed frames, shelves, storage areas, stages, railings, partitions, and toy systems, several embodiments of the assemblies are presented to illustrate various aspects of the multifunctionality of the module component components described herein. Embodiments 1 to 10, shown in Figures 34 to 43, are configured for use with various types of cameras. However, the illustrated assemblies may be used with other types of devices such as microphones, lighting, telescopes, lasers, and measuring and surveying tools. Embodiment 11, shown in Figure 44, is configured for use with industrial lighting. Embodiments 12 to 14, shown in Figures 45 to 47, are configured to be used as various types of utility carts for transporting various types of materials, supplies, and equipment. The modules disclosed herein can also be configured into assemblies used as furniture or storage areas, as shown in Figure 48.

[0185] Example 1: Club Steering Dolly System Figure 34 shows a perspective view of one embodiment of a club-steering dolly system 700, configured using some of the modules and assemblies disclosed herein, and is designed to provide a trackless, operator-controlled club-steering assembly for transporting a camera or other equipment on a film set or other location. Note that in this embodiment, “rear” or “back” refers to the side of the assembly facing the location where the operator operating the dolly system would stand in the drawing, and “front” or “fore” refers to the side of the assembly facing away from the drawing. The Crab Steering Dolly 700 comprises two subassemblies: the first subassembly is a pivotable and rotatable device support structure supported by a pair of rail-enclosed rolling module assemblies 537; and the second subassembly is a steerable dolly framework comprising (i) an elongated rail assembly on which the rail-enclosed rolling modules 537 can be moved; (ii) a pair of Crab steering wheel modules 550 at each corner; and (iii) a steering assembly for pivotable control of the wheel modules.

[0186] The device support subassembly includes a base plate assembly 400 to which a camera or other screw-mounted device can be attached. To the right of the base plate assembly 400 is a pan / tilt / jib operating handlebar assembly, which engages to allow an operator to manually control the orientation and position of the base plate. The pan / tilt / jib operating handlebar assembly includes a 6-unit length double-sided receptacle extension tube rotator module 151 and a closed tube rotator hub assembly 100, which has a rigid end cap component 690 attached and a downward-extending grip end cap module 625. From the left side of the base plate module 400 extends a 4-unit length male / receptacle lateral opening jointer module 251, which is attached to the closed tube rotator hub assembly 100 to provide an intermittently lockable tension-adjustable 360° device tilt pivot point that can be controlled by the handlebar assembly on the right side of the base plate. The grip end cap module 625 engages with a left-facing male member of the hub assembly 100 to provide an additional handgrip. Extending downward from the rotator hub assembly 100 is a 10-unit double-sided receptacle extension tube rotator module 710, which can provide a lockable or off-center 360° device pan pivot where it meets another rotator hub assembly 100, to which a 6-unit length double-sided receptacle extension tube jointer module 460 is attached, followed by another closed-tube rotator hub assembly 100 with a bumper component 672 engaged with an upward-facing wide pivot segment, which meets a 3-unit male / receptacle extension tube jointer module 720 below, providing an intermittently lockable tension-adjustable 360° device pan pivot centered below a camera or other specific device, with the tension of the pivot adjustable using a tension adjustment screw knob 58.

[0187] Below the jointer module 720 is a closed-pipe rotator hub assembly 100, to which two further closed-pipe rotator hub assemblies 100 (each fitted with a grip end cap module 625) engage on either side. From these two further closed-pipe rotator hub assemblies 100, two 12-unit length double-sided receptacle extension tube jointer modules 475 extend downward to their respective rotator hub assemblies 100 (bringing the jib tilt pivot point inward for the upper assembly). These rotator hub assemblies 100 engage in a stack of two further rotator hubs 100 (bringing the jib pan pivot point for the upper assembly) in the center. The jib tilt and jib pan can be controlled using grip end cap modules 625 attached to the ends of an 18-unit double-sided receptacle extension tube jointer module 730 by a zero-unit length double-sided male jointer module 281 (invisible). The Joiner Module 730 is further fitted with a Balance Weight Module Assembly 600.

[0188] Below the two stacked rotator hubs 100 described above, the device support structure is attached to the rail-encircling rolling module assembly 537 via six-unit-length double-sided receptacle extension tube joiner modules, each having a closed-tube rotator hub assembly on each side, which is mounted on the rail-encircling rolling module assembly 537. In this embodiment, it runs along two parallel 36-unit double-sided receptacle extension tube joiner modules 740 that engage in the center via the closed-tube rotator hub assemblies and six-unit double-sided receptacle extension tube joiner modules 460 at each end, allowing small tracking movements relative to the dolly assembly below. Below the double-sided receptacle extension tube joiner modules 460, a laterally mounted four-unit male / receptacle extension tube joiner module 750 and subsequent closed-tube rotator hub assemblies engage the device support structure and rail assembly with a steerable dolly subassembly.

[0189] A steerable dolly subassembly supports a device support subassembly and provides a chassis structure that engages with the rail assembly by a rail-enclosing rolling module assembly 537. The chassis assembly has a four-way closed-tube jointer hub assembly 201 in its center, from which four extension tube jointer modules extend in all four directions, the longest being 18 units of bilateral receptacle extension tube jointer modules 730 extending rearward from the center of the assembly, where a four-way closed-tube rotator hub assembly 100 connects to the rail assembly above and 12 units of bilateral receptacle extension tube jointer modules 475 extending laterally to the two rear corners of the chassis. From the central four-way closed-tube jointer hub assembly 201, 12 units of jointer modules extend forward, continuing to 4 units of jointer modules that engage with the rail assembly at the front. Two 12-unit joiner modules extend from each of the lateral faces of the central joiner hub assembly 201, leading to the two front corners of the chassis assembly.

[0190] A closed-tube rotator hub assembly 100 engages with each corner of the chassis assembly, and six units of male / receptacle extension tube rotator modules 640 engage downward from each of them, providing directional pivots to each wheel module assembly 550. Below each of these rotators 640, a four-way closed-tube rotator hub assembly 100 is engaged, located in the center of the pair of wheel modules 550. From the rear of each of these hub assemblies, six units of bilateral receptacle extension tube joiner modules 460 extend, meeting another rotator hub assembly 100, from which six units of bilateral receptacle extension tube rotator modules 151 extend upward, providing pivots for the steering assembly.

[0191] Each of the upward-extending rear rotator modules 640 is fitted in series with a rotator hub assembly 100, two units of double-sided male jointer modules 291, and another rotator hub assembly 100. Each of the upward-extending front rotator modules 640 is fitted with four units of double-sided male extension tube jointer modules 756 and a rotator hub assembly 100. On the left and right sides of the dolly, eighteen units of double-sided receptacle extension tube jointer modules 730 interconnect the upper rotator hub assemblies of the steering assemblies for the front and rear rotator modules, which are interconnected to the wheel module 550. A pair of twelve units of double-sided receptacle extension tube jointer modules 475 extend inward from the lower rotator hub assembly 100 mounted on the rearward-extending upward rotator module 640 and engage with a four-way closed tube jointer hub assembly of a different configuration. A weight module assembly 600 extends rearward from the jointer hub assembly, consisting of six units of bilateral receptacle jointer modules. A twelve-unit male / receptacle extension tube jointer module 754 extends upward from the jointer hub assembly, engaged with a four-unit bilateral male extension tube jointer module 756 having three grip end cap modules 625. The subassembly described in this paragraph includes a steering assembly that allows the operator to steer the club steering dolly 700 by pushing and pulling it using the grip end cap modules 625. In this embodiment, the force applied by the operator to the steering assembly allows for a turning radius of approximately 140° of the wheel, so that pushing the assembly forward and to the left causes the wheel module 550 to orient to the right, and conversely, pushing it forward and to the right causes the wheel module to orient to the left.

[0192] Example 2: Vertical Rail Tracking Dolly System An embodiment of the vertical rail tracking dolly system 760 is shown in Figure 35 and can be used to provide stable support for controlling vertical up-and-down movement of a mounted device, such as a still camera, video camera, or film camera, during the acquisition of video or still images. A wheel module allows an operator to push and pull the vertical rail tracking dolly system 760 as desired while operating the mounted device.

[0193] The vertical rail tracking dolly system 760 comprises two subassemblies: the first subassembly is a dolly framework provided with a pair of wheel modules 550 at each corner and a vertical, elongated rail structure on which a rail-enveloping rolling module assembly 537 can be moved; and the second subassembly is a pivotable and rotatable camera support structure provided on the dolly framework, comprising a pair of rail-enveloping rolling module assemblies 537 that move up and down along the vertical, elongated rail structure.

[0194] The dolly framework subassembly consists of a first pair of 18 units of double-sided receptacle extension tube joiner modules 730, spaced apart, which at each end are laterally attached to a second pair of 18 units of double-sided receptacle extension tube joiner modules 730, spaced apart, and which at each end are engaged to a closed-tube rotator hub assembly 100, to which rigid socket cap components 690 are attached. From each rotator hub assembly 100, six units of male / receptacle extension tube rotator modules 640 extend downward, providing directional pivots for the wheel modules 550 of the dolly system, which are laterally attached to both sides of the rotator hub assembly 100, located at the bottom of each extension tube rotator module 640. In this embodiment, the wheel 552 is bolted to the wheel axle / receptacle lateral opening jointer module 555 of the wheel module 550 in a corresponding axle offset threaded hole 551b (not visible), so that these wheel module assemblies function as a large caster and rotate naturally in a direction that aligns with the directional force that the operator applies to the dolly assembly. As shown in Figure 35, the wheel module assembly includes a weight module assembly 600 that is laterally attached to the jointer module, which has a flat end cap component 695 extending from a third central face of the rotator hub assembly.

[0195] The vertical, elongated rail structure comprises two rails, each consisting of an 18-unit double-sided receptacle extension tube jointer module 730 at the lower end, which engages with an 18-unit upper male / receptacle extension tube jointer module 765. The lower end of the rail structure is attached laterally to the longitudinal square nut channels of a first pair of horizontally mounted jointer modules 730. A rigid socket cap component 690, serving as a protective enclosure for the two receptacles, is inserted into the upper end of the rail structure.

[0196] A second subassembly, namely a pivotable and rotatable camera support structure, comprises a base plate assembly 400 to which a camera or other screw-mounted device can be attached. On the left side of the base plate assembly 400 (as shown in the diagram in Figure 35), a pan / tilt / jib operating handlebar assembly is engaged to allow an operator to manually control the direction and position of the base plate. The pan / tilt / jib operating handlebar assembly comprises a first double-sided receptacle extension tube rotator module 151 and a closed tube rotator hub assembly 100 having a rigid socket cap component 690 attached and a downward-extending grip end cap module 625. From the right side of the base plate assembly 400, a male / receptacle lateral opening jointer module 251 extends and engages with the closed tube rotator hub assembly 100, so that the base plate assembly 400 can be controlled by the handlebar assembly on the left side of the base plate assembly by providing an intermittently lockable tension-adjustable 360° tilt axis. A grip end cap module 625 is attached to the outer male member assembly of the rotator hub assembly 100 as an auxiliary gripping point. Ten units of double-sided receptacle extension tube rotator module 710 extend downward from the rotator hub assembly 100, which can provide an off-center pan axis at the lower part where it meets the closed-tube jointer hub assembly 201, and a first double-sided receptacle extension tube jointer module 460 is attached to the side of the closed-tube jointer hub assembly 201, and the first double-sided receptacle extension tube jointer module 460 engages with the closed-tube rotator hub assembly 100, which has a bumper component 672 engaged with an upward-facing wide pivot segment for protection against a camera or other device that may accidentally collide with the hub assembly by rotation on a 360° tilt axis.The rotator hub assembly 100 provides an intermittently lockable tension-adjustable pan shaft for the base plate assembly where it meets three units of male / receptacle extension tube joiner module 720, which extend downward from the rotator hub assembly and are laterally mounted to a second double-sided receptacle extension tube joiner module 460. A pair of 18-unit double-sided receptacle extension tube joiner modules 730 engage with both ends of the second joiner module 460, rotatably engage with both ends of the second rotator module 151, and engage with the third joiner module 460. A balance weight module assembly 600 is laterally mounted near the lower ends of each of the pair of double-sided receptacle extension tube joiner modules 730. One end of another 18-unit double-sided receptacle extension tube joint module 730 is attached laterally to a rotatably engaged second rotator module 151, and the other end is attached laterally to a third rotator module 151. Another extension tube jointer module 730 is attached laterally to the opposite side of the third rotator module 151 by one end and has a balance weight module assembly 600 attached to the opposite end. A pair of rotator hub assemblies 100, having rigid end cap components 690 and outer grip end cap modules 625, engage with the receptacles at both ends of the third rotator module 151, so that the upper part of the support assembly can be pivoted up and down, and the extending vertical portion of the assembly can be kept vertical by rotation in the second rotator module 151 if desired. A pair of rotator hub assemblies 100 are engaged below a pair of double-sided receptacle extension tube jointer modules 460, which are then attached to a pair of jointer hub assemblies 201 interconnected by another double-sided receptacle extension tube jointer module 460. A rail-enclosing rolling module assembly 537 is attached to the rail-facing receptacles of the pair of jointer hub assemblies 201.

[0197] The rail-enclosed rolling module assembly 537 moves glidingly around a vertical, elongated rail structure configured on a dolly framework subassembly and is movable up and down along the vertical, elongated rail structure by an operator using grip end cap modules 625 attached to the sides of a pair of rotator hub assemblies 100 engaged with a third rotator module 151 and the rolling module assembly 537. To buffer the camera's movement as the rail-enclosed rolling module assembly 537 moves to the bottom of the vertical, elongated rail structure, a pair of female dome pad end cap modules 641 can be attached laterally to the intermediate horizontal side-by-side receptacle extension tube jointer module 460 of the second subassembly and the corresponding 18-unit extension tube jointer module 730 of the first subassembly.

[0198] Example 3: Horizontal Rail Tracking Dolly System An embodiment of the horizontal rail tracking dolly system 770 is shown in Figure 36. This type of assembly configuration can be used to provide a horizontal rail system that can be firmly fixed between two opposing, stable vertical supports, such as between two walls or between two doors or windows inside a vehicle. An operator can controllably reciprocate an equipment support assembly engaged with one or more rail-enclosed rolling module assemblies 537 (or optionally, rail rolling modules 510) along the horizontal rail system.

[0199] In this embodiment, the horizontal rail system comprises 36 units of double-sided receptacle extension tube jointer modules 740, which are detachably engaged at one end with a pivotable support module 590 to which pad components 594 are attached. The other end of the jointer modules 740 engages with a telescopic extension module 610, which is attached to the pivotable support module 590 to which pad components 594 are attached. The horizontal rail system can be firmly mounted in place between two vertical support surfaces by the telescopic engagement of the telescopic extension module 610 with these two surfaces. If necessary, a similar alternative assembly (not shown) can also be engaged vertically between the two horizontal support surfaces.

[0200] In this embodiment, the base plate assembly 430 shown in Figure 17 is attached laterally to the three male / receptacle extension tube joiner modules 720 at the upper ends of each of the six male / receptacle extension tube joiner modules 465. Each downward-facing wide pivot segment of the male member tube end assembly 270 of the joiner module 465 engages with the bumper component 672 (the male component 70 shown in Figure 17 is omitted here). The outer male ends of the three joiner modules 720 each engage with the closed tube rotator hub assembly 100. A downward-extending grip end cap module 625 and a left-facing bumper component 672 engage with the left-side rotator hub assembly 100 of the base plate assembly 430, while the right-side rotator hub assembly 100 of the base plate assembly 430 engages with a right-facing bumper component 672 and a downward-extending assembly consisting of three units of male / receptacle extension tube joiner modules 720 that engage with six units of double-sided receptacle rotator modules 151, the six units of double-sided receptacle rotator modules 151 engaging with a closed-tube joiner hub assembly 201. The corresponding ends of the six-unit double-sided receptacle extension tube joiner module 460 engage with a laterally mounted male member assembly extending from the joiner hub assembly 201, while the other end of the joiner module 460 engages with a rotator hub assembly 100 which is rotatably engaged with a male member plate assembly on the rail encircling rolling module assembly 537, the rotator hub assembly 100 having a tension adjustment screw knob 58 for adjusting the intermittently lockable 360° pan shaft pivot tension provided by the rotator hub assembly 100.A bumper component 672 engages with the upward-facing wide pivot segment of the pan-axis rotator hub assembly 100 to protect a camera or other device that could accidentally come into contact with the hub assembly 100 due to the rotation of the base plate assembly 430 in a 360° tilt axis, which brings the right-side horizontal 3-unit male / receptacle jointer module 720 to a location where it rotatably engages within the corresponding rotator receptacle 11 of the hub assembly 100.

[0201] Example 4: Rolling Jib System An embodiment of the rolling jib system 780 is shown in Figure 37 and is configured to provide a compact and lightweight rolling stand system for supporting luggage or equipment such as a still camera, video camera, or film camera. Such a jib assembly can be configured to extend outward, for example, a microphone or lighting fixture.

[0202] In this embodiment, each of a pair of 10-unit wheel axle / receptacle lateral opening jointer modules 800 is laterally attached at one end to both sides of the first closed-tube rotator hub assembly 100. At the other end, a wheel 552 is rotatably engaged with the central hole of each wheel axle tube end component 551. One end of an 18-unit double-sided receptacle extension tube jointer module 730 engages with a male member assembly extending outward from the first rotator hub assembly 100. The other end of the jointer module 730 is attached to the male member assembly of the second closed-tube rotator hub assembly 100. A weight module assembly 600 on a male jointer, to which a flat end cap component 695 is attached, engages with the outward-facing receptacle of the second rotator hub assembly 100. A downward-extending grip end cap module 625 is mounted laterally to the second rotator hub assembly 100. A third rotator hub assembly 100 is mounted laterally at a 90° interval from the grip end cap module 625. A 36-unit double-sided receptacle extension tube jointer module 740, extending upward, is mounted laterally to the third rotator hub assembly 100.

[0203] In this embodiment, a first double-sided receptacle extension tube joiner module 460, extending to the right (as shown in Figure 37), is engaged with the base plate assembly 400. A fourth rotator hub assembly 100, with three grip end cap modules 625 spaced 90° apart to handle the tilt and pan movements of the base plate assembly, is engaged with this first double-sided receptacle extension tube joiner module 460. One end of the second double-sided receptacle extension tube joiner module 460 is attached to the left side of the base plate assembly 400, while the other end is engaged with a fifth rotator hub assembly 100, which is engaged with a downward-extending 10-unit double-sided receptacle extension tube joiner module 790. A sixth rotator hub assembly 100 is engaged with the other end of the joiner module 790. One end of the third double-sided receptacle extension tube joiner module 460 is attached laterally to the sixth rotator hub assembly 100. The other end of the third joiner module 460 engages with the double-sided male extension tube joiner module 291, which, at its other end, engages with the seventh rotator hub assembly 100, thereby providing a tilt axis to the upper base plate assembly 400. Adjacent below, where the upward-facing rotator receptacle 11 of the eighth rotator hub assembly 100 rotatably engages with a male member lateral mount assembly 110 or 395 extending downward from the seventh rotator hub assembly 100, the upper base plate assembly 400 is provided with a centrally located 360° pan axis.A ninth rotator hub assembly 100 is mounted laterally to the eighth rotator hub assembly 100, and in this location, when the jib arm jointer module 740 engaged with the ninth rotator hub assembly 100 is moved upward or downward from the location of the rotatable engagement between the third rotator hub assembly 100 and the second rotator hub assembly 100, which is engaged with the lower end of the jib arm jointer module 740, in a high-tension setting or in intermittently lockable rotation using the pivot lock 60, the pan shaft rotator hub assembly 100 and the upper module can be made horizontal again.

[0204] A female dome pad end cap module 641 is attached laterally to the joiner module 730 to buffer the jib arm assembly when it is desired to lower the upper jib arm assembly to a position adjacent to the joiner module 730. Three grip end cap modules 625 attached to the fourth rotator hub assembly 100 are provided for the operator's hand to control the tilt and pan rotation of the support assembly. By holding this handgrip assembly and optionally gripping the jib arm (i.e., the joiner module 740), the operator can lift the jib arm to raise the grip end cap modules 625 extending downward, and then push and pull the rolling jib assembly 780 to roll the rolling jib assembly 780.

[0205] Example 5: Low-angle base plate support system One embodiment of the low-angle baseplate support system 810 is shown in Figure 38 and is configured to provide a compact, low-rolling baseplate system in which driving and rotational motion is performed by pushing and pulling by an operator who grasps two handle attachments that extend upward from two subassemblies within reach of an operator in a standing or walking position. This assembly can be rolled by the operator when lifting the chassis steering bar assembly, and the chassis steering bar assembly comprises a closed-tube rotator hub assembly 100 (having two laterally mounted grip end cap modules 625), to which a male / receptacle extension tube joiner module 465 is connected, and then there are 18 units of double-sided receptacle extension tube joiner modules 730, which are laterally mounted in the middle of 18 units of double-sided receptacle extension tube rotator modules 830 that form the rear of the chassis assembly, allowing the two rear corner grip end cap modules 625 to be lifted off the ground and the system assembly to move forward.

[0206] Below the two rear corner rotator hub assemblies 100, the extended length of the grip end cap module 625 is combined with one unit of double-sided male extension tube joiner module 840, which aligns the chassis assembly to be roughly horizontal with respect to the radius of the two wheel modules 550. From each of the two rear corner rotator hub assemblies 100, six units of double-sided receptacle extension tube joiner module 460 extend forward and connect to the two front rotator hub assemblies 100, to which the wheel module assembly 550 is mounted on the outside of each of the front rotator hub assemblies 100. Two 4-unit male / receptacle extension tube rotator modules 820 extend upward from two front rotator hub assemblies 100, onto which two rotator hub assemblies 100 engage, each of which has an inwardly facing rotator receptacle 11, thereby providing a tilt axis to a base plate assembly 400 that engages between two male / receptacle extension tube joiner modules 465 rotatably engaged to the rotator hub assemblies on each side. A tilt axis steering bar assembly is mounted laterally to the left joiner module 465, and the tilt axis steering bar assembly contains the same modules as the lower chassis steering bar assembly, but the orientation of the horizontal grip end cap module 625 is reversed, and here it is configured to operate the tilt motion of the base plate assembly 400, and further configured to grip for steering and rolling forward of the system.

[0207] Example 6: Lateral Ground Rail Tracking Dolly System One embodiment of the lateral ground rail tracking dolly system 850 is shown in Figure 39 and is configured to provide a fixed rail track system for rolling a camera or other equipment in the requirements of film production or other end-uses of a similar nature.

[0208] This embodiment comprises three subassemblies: the first subassembly is a fixed rail track system; the second subassembly is a pivotable and rotatable camera support structure; and the third subassembly is a support framework for the second subassembly, which includes two pairs of rail rolling modules 510.

[0209] The first subassembly comprises a pair of rail tracks, each consisting of two 36-unit double-sided receptacle extension tube joiner modules 740 interconnected by a rotator hub assembly 100, with the outward-facing ends of the joiner modules 740 engaged with the rotator hub assembly 100. An 18-unit extension tube joiner module 730 is attached laterally to the rotator hub assembly 100 at each end of the rail track. One end of a downward-extending double-sided receptacle extension tube joiner module 460 is attached laterally to each of the six rotator hub assemblies in the first subassembly, with the other end of the downward-extending double-sided receptacle extension tube joiner module 460 engaging with a leveling foot module 580. The joiner module 730 is attached laterally to two intermediate downward-extending joiner modules 460 to provide structural support to the rail track subassembly.

[0210] A second subassembly comprises a base plate assembly 400 to which a camera or other screw-mounted device can be attached. To the right of the base plate assembly 400 is a pan / tilt / jib operating handlebar assembly, which engages to allow an operator to manually control the orientation and position of the base plate. The pan / tilt / jib operating handlebar assembly comprises a 6-unit length double-sided receptacle extension tube rotator module 151 and a closed tube rotator hub assembly 100 having a rigid end cap component 690 attached and a downward-extending grip end cap module 625. From the left side of the base plate module 400 extends a 4-unit length male / receptacle lateral opening jointer module 251, which is attached to the closed tube rotator hub assembly 100 to provide an intermittently lockable tension-adjustable 360° device tilt pivot point that can be controlled by the handlebar assembly on the right side of the base plate. The grip end cap module 625 engages with a left-facing male member of the hub assembly 100 to provide an additional handgrip. Extending downward from the rotator hub assembly 100 is a 10-unit double-sided receptacle extension tube rotator module 710, which can provide a lockable or off-center 360° device pan pivot where it meets another rotator hub assembly 100, to which a 6-unit length double-sided receptacle extension tube jointer module 460 is attached, followed by another closed-tube rotator hub assembly 100 with a bumper component 672 engaged with an upward-facing wide pivot segment, which meets a 3-unit male / receptacle extension tube jointer module 720 below, providing an intermittently lockable tension-adjustable 360° device pan pivot where it is centered below the center of a camera or other particular device, and the tension of the pivot can be adjusted using a tension adjustment screw knob 58.

[0211] Below the jointer module 720 is a closed-pipe rotator hub assembly 100, to which two further closed-pipe rotator hub assemblies 100 (each fitted with a grip end cap module 625) engage on either side of this closed-pipe rotator hub assembly 100, from which two 12-unit length side-side receptacle extension pipe jointer modules 475 extend downward to their respective rotator hub assemblies 100 (bringing the jib tilt pivot point inward for the upper assembly), and these rotator hub assemblies 100 engage in the center with a closed-pipe jointer hub assembly 201, to which side-side receptacle rotator modules 151 extending downward are fitted to the sides of this closed-pipe jointer hub assembly 201, providing the jib pan pivot point for the upper assembly at the location of rotatable engagement with a third subassembly. The jib tilt and jib pan can be controlled using grip end cap modules 625 attached to the ends of 18-unit double-sided receptacle extension tube jointer modules 730 by double-sided male jointer modules 281 (not visible) of zero unit length. A balance weight module assembly 600 is further attached to the jointer module 730.

[0212] The third subassembly comprises a rolling framework consisting of joiner modules 730, each engaged with a closed-pipe joiner hub assembly 201 at its respective end. Double-sided receptacle joiner modules 460 extend laterally from each joiner module 201. Another closed-pipe joiner hub assembly 201 engages with the outward-facing end of each joiner module 460. An upward-facing male member plate assembly 420 of the rail rolling module 510 engages with the receptacle of the closed-pipe joiner hub assembly 201. A grip end cap module 625 is provided at the upward-facing male end of the closed-pipe joiner hub assembly 201. As described in the paragraph above, one end of the double-sided receptacle extension tube rotator module 151 is attached to the side of the joiner module 730, and the other end is rotatably engaged with a closed tube joiner hub assembly 201 that interconnects the lower pair of rotator hub assemblies 100 in the second subassembly.

[0213] Example 7: Double Base Plate Type A Frame Dolly System An embodiment of the 860 double baseplate A-frame dolly system is shown in Figure 40 and is configured for use in applications such as filmmaking where it may be necessary to move two side-by-side cameras or other such devices in combination. This embodiment comprises two subassemblies, the first of which is a rolling A-frame dolly structure, and the second of which is a rotating support structure for two cameras or other such devices.

[0214] The first subassembly has an A-frame structure consisting of two A-frames, each A-frame being interconnected by three 36-unit double-sided receptacle extension tube jointer modules 740, with two bidirectional 30° lateral mounting bracket modules 320 at the two lower joints (see Figure 13A) and a 30° angled male member mounting bracket 322 at the upper joint. The two A-frames are interconnected at (i) the bottom, which is slidably or firmly fastened to the two 36-unit double-sided receptacle extension tube jointer modules 740, and at (ii) the top, where the mounting brackets 322 are attached to an 18-unit extension tube jointer module 730 by two mounting screws 325, which respectively screw into square nuts provided in the longitudinal channels on both sides of the jointer module 730. The first subassembly has four sets of wheel assemblies, each set comprising a pair of wheel modules 550 mounted on either side of the rotator hub assembly 100. In this embodiment, each wheel 552 is bolted to the corresponding wheel axle / receptacle lateral opening jointer module 555 in a corresponding axle offset threaded hole 551b (not visible), so that they function as large casters and rotate naturally in a direction that aligns with the directional force applied by the operator to the dolly assembly. The assembly includes a weight module assembly 600 mounted laterally to the jointer module, which has a flat end cap component 695 extending from a third central surface of the rotator hub assembly 100. An upward-extending male / receptacle extension tube rotator module 640 is rotatably engaged with the rotator hub assembly 100 by its male end, allowing for 360° rotation within the upward-facing rotator receptacle 11 of the rotator hub assembly 100, while the other end of the rotator module 640 is firmly engaged with a male member lateral mount assembly 110 or 395 within the corresponding outward-facing jointer receptacle 211 of the corresponding 36-unit double-sided receptacle jointer module 740.

[0215] The second subassembly has two separately located baseplate modules 400, each having individual 360° pan axis pivots and which may also be able to rotate together 360° at a central pan axis pivot. Each baseplate module 400 has a pair of grip end cap modules 625 attached to the left and right male member plate assemblies 420 of module 400. One end of a double-sided receptacle extension tube rotator module 151 is attached to a male member plate assembly 420 extending downward from module 400, and the other end of the rotator module 151 is interconnected to the male end of a closed tube jointer hub assembly 201. The downward-extending grip end cap modules 625 engage with each jointer receptacle 211 by a zero-unit double-sided male jointer module 281 (not visible, see Figure 9). Joiner modules 730, which engage with male member lateral mounting assemblies extending inward from each joiner hub assembly 201, are interconnected on both sides of the rotator hub assembly 100, which provides a central 360° pan axis point. Shell end cap modules 635 engage with the upper part of the rotator hub assembly 100, while the lower female end of the rotator hub assembly 100 is rotatably engaged with the male end of a 4-unit male / receptacle joiner module 750. The female end of the joiner module 750 is laterally attached to a joiner module 730 that interconnects two A-frames. A joiner module 730, which provides a central pan operating handlebar, extends from a third side of the rotator hub assembly 100 and engages with a grip end cap module 625, which is attached at its outer end by a zero-unit bilateral male joiner module 281 (not visible).

[0216] Example 8: 4-Caster Base Plate Dolly System One embodiment of the 4-caster base plate dolly system 870 is shown in Figure 41 and is configured for use in applications such as filmmaking where it is desirable to bring a camera or other such device mounted on a rolling framework as close as possible to the ground, platform, or table.

[0217] This embodiment consists of two pairs of caster wheel module assemblies 560, as described with reference to Figures 23C and 23D. Each pair comprises two caster assemblies 560 capable of 360° pivoting, with each assembly 560 engaging at one end of a double-sided receptacle extension tube joiner module 460, which at the other end engages with a closed-tube rotator hub assembly 100. The two rotator hub assemblies 100 are interconnected to the joiner module 460. The right-side male member plate assembly 420 of the base plate assembly 400 engages at one end of the first double-sided receptacle rotator module 151. The other end of the first double-sided receptacle rotator module 151 is laterally attached to the right-side joiner module 460, which interconnects the corresponding pair of caster assemblies 560. The left-side male member plate assembly 420 of the base plate assembly 400 engages with one end of a second double-sided receptacle rotator module 151. The other end of the second rotator module 151 is laterally attached to the left-side jointer module 460, which interconnects the other pair of caster assemblies 560. The combination of the two rotator modules 151 provides a tilt axis point that can be rotated 360°, depending on the length of the device to which the base plate module 400 is attached, or intermittently locked by one or both of the pivot locks 60, which engage with the pivot lock sprocket 423 (not visible) of the male member plate assembly 420.

[0218] Example 9: Handheld Camera Stabilizer Assembly An example of a hand-held stabilizer assembly 880 for camera support is shown in FIG. 42 and is configured for use in applications where hand-held support is required for tools or devices such as cameras that can be attached to a base plate assembly. In this example, one end of a double-sided receptacle joiner module 460 engages with a male member plate assembly 420 on the right side of the base plate assembly 400, and the other end engages with a first closed tube rotor hub assembly 100. The female end of an 18-unit male / receptacle extension tube joiner module 765 that extends downward engages with the male end of the rotor hub assembly 100, and a grip end cap module 625 is provided at the male end of the joiner module 765. A male member plate assembly 420 on the left side of the base plate assembly 400 engages with one end of a double-sided receptacle rotor module 151. The other end of the rotor module 151 engages with a second rotor hub assembly 100. One end of an 18-unit male / receptacle extension tube joiner module 765 that extends horizontally engages with the second rotor hub assembly 100, and the other end of the joiner module 765 engages with a female dome pad end cap module 641.

[0219] The operator can stably operate a camera attached to the base plate module 400 by placing the horizontally extending joiner module 765 or the female dome pad end cap module 641 on their shoulder, or by holding the joiner module 765 with their left hand and pressing the female dome pad end cap module 641 against their chest while holding the downward extending grip end cap module 625 with their right hand, and can tilt the angle of the camera up and down at the tilt axis point provided by the double-sided receptacle rotor module 151.

[0220] Example 10: Vertical Rail Tracking Stand Assembly An example of a vertical rail tracking stand assembly 900 is shown in FIG. 43 and is configured for use in applications where a tool such as a camera or a load needs to be vertically moved up and down at a set standing position. This example includes two sub-assemblies, where the first sub-assembly is a vertical rail stand and the second sub-assembly is a pivotable and rotatable rolling support for a camera or other types of devices or tools.

[0221] The first sub-assembly is a vertical rail that includes an 18-unit male / receptacle extension tube joiner module 765 interconnected with a 36-unit double-sided receptacle extension tube joiner module 740. The joiner module 740 is attached to a male member plate assembly 420 on a weighted footplate 586 of a footplate module 585.

[0224] Example 11: Lighting support rack system An embodiment of the lighting support rack system 910 is shown in Figure 44 and can be configured for use in applications such as film production where industrial lighting or grip fixtures are used. This type of configuration may also be useful for supporting other types of loads, such as audio equipment and video display equipment.

[0225] In this embodiment, a three-shaft lighting support rack assembly extends vertically from a base assembly of four casters to which weights are attached. The base assembly comprises four matching weighted caster leg assemblies, each having 18 units of double-sided receptacle extension tube joiner modules 730. These weighted caster leg assemblies extend from the sides of horizontal 36-unit double-sided receptacle extension tube joiner modules 740 at the bottom of the lighting support rack assembly, in pairs on two multi-angle male member mounting brackets 335, and are mounted in 60° angled holes in the multi-angle male member mounting brackets 335 such that an angle of separation of 120° is formed between the extensions of the two legs. Another mounting bracket 335 is connected to each outer end of the double receptacle extension tube joiner module 730 via a 60° angled hole in the bracket, such that a second 60° angled hole is aligned perpendicular to the ground. Six vertically aligned units of double receptacle extension tube joiner modules 460 and caster module assemblies 560 are connected to this second 60° angled hole, completing each leg assembly. If load balancing of the upward-facing lighting support rack assembly is required, a series of weight components 602 can be fixed to the sides of the 18 units of double receptacle extension tube joiner modules 730, as shown in Figure 44.

[0226] Three mounting shafts extend upward from a horizontal 36-unit double-sided receptacle extension tube rotator module 740 at the bottom of the lighting support rack assembly, each comprising two 36-unit double-sided receptacle extension tube rotator modules 920 connected by zero-unit double-sided male jointer modules 281. On each rotator module 920 is mounted a repositionable 90° offset lateral mount bracket module 340, to which is an L-shaped mount arm assembly comprising a closed-tube jointer module hub assembly 201, followed by a 6-unit double-sided receptacle extension tube rotator module 460, and a further closed-tube jointer module hub assembly 201 to which a vertically aligned 5 / 8-inch spigot lighting mount module 490 having a spigot 498 capable of supporting various industrial lighting fixtures is connected. The vertical position of the mounted fixture can be adjusted by changing the position of the lateral mounting bracket module 340, which is 90° offset on the corresponding square nuts in the square nut channels along the 36-unit double-sided receptacle extension tube rotator module 920. The mounted fixture can also be pivoted 360° horizontally by rotating the 36-unit double-sided receptacle extension tube rotator module 920, if the size or spacing of the fixtures allows, where three of the double-sided receptacle extension tube rotator modules 920 are connected on top of a horizontal 36-unit double-sided receptacle extension tube joiner module 740, and three are connected on top of the first three. For the structural integrity of these forms of lighting support rack assemblies, an additional horizontal 36-unit double-sided receptacle extension tube joiner module 740 is connected to the ends of the upper three 36-unit double-sided receptacle extension tube rotator modules 920 to complete the rectangular frame of the lighting mount assembly.
