Interlock multifunctional construction engineering device

Abstract

Construction tools, such as for use in high altitude construction (telecommunication towers, buildings, and other tall structures) often require different features. Some tools are used for lifting or moving heavy loads, others are used to hold or support tools and / or people, and other times, unique tools are required for tasks as they arise. Thus, a multifunctional system or device provides the ability to perform the different tasks without requiring a new tool. The device can be manipulated or rearranged with add-ons to create needed functionality for the operator's need. This can include lifting, moving, supporting, etc., and can meet load standards and other requirements.

Description

Docket No. P14510WO00 1TITLE: INTERLOCK MULTIFUNCTIONAL CONSTRUCTION ENGINEERING DEVICECROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority under 35 U.S.C. § 119 to provisional patent application U.S. Serial No. 63 / 586,836, filed September 29, 2023. The provisional patent application is herein incorporated by reference in its entirety, including without limitation, the specification, claims, and abstract, as well as any figures, tables, appendices, or drawings thereof.TECHNICAL FIELD

[0002] The present disclosure relates generally to systems and apparatus for use in the construction industry. More particularly, but not exclusively, the disclosure includes systems and apparatus for multifunctionality in the construction industry, such as for lifting or using with high altitude construction, or for construction work at any elevation. It should be noted that the present disclosure may also relate to systems and apparatus for use in non-construction industries.BACKGROUND

[0003] The background description provided herein gives context for the present disclosure. Work of the presently named inventors, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art.

[0004] Construction, such as below ground elevation, at ground elevation, or at any elevation such as support of excavation, concrete formwork systems, shoring, and the like, requires many unique tools and devices. In addition, construction, such as high altitude construction of buildings, towers, and the like, requires many unique tools and devices. Some are used for lifting components of the construction. Others may be used for moving the components both vertically and laterally at the raised altitude. Still others may be used to support or transfer loads, for support of excavation, formwork systems, falsework systems, scaffolding, temporary walkways, stands, fall protection, or supports for the workers doing the construction. In general, there are little to no devices available on the market for construction engineeringDocket No. P14510WO00 2 devices that can be transformed from one construction device into an almost unlimited number of other construction devices.

[0005] Instead, as noted, the contractor may require several different devices specific to certain applications to complete their work. This means that the contractor must purchase, maintain, haul, and / or store all these various devices to complete their work. At times, the contractor may need to create a tool in situ for a task. The contractor may need a device that is not available and / or not in their location and may try to piece something together to complete their work without needed engineering verifications for the intended use or application resulting in completing their work less efficiently, and / or safety incidents, and / or schedule delays and / or quality / workmanship issues.

[0006] One portion of high altitude construction includes the use of gin poles. A gin pole is a supported pole that uses a pulley or block and tackle on its upper end to lift loads. The lower end is braced or set in a shallow hole and positioned so the upper end lies above the object to be lifted. The pole (also known as a mast, boom, or spar) is secured with anchor supports or slings / cables. These are manipulated to move the load laterally, with up and down controlled by the pulley or block. In tower construction, a gin pole can also be "jumped" up the completed sections of a tower to lift the higher sections into place. Gin poles are also mounted on trucks as a primitive form of mobile crane, used for lifting and relocating loads.

[0007] In general, there are little to no devices available on the market for gin poles that can be transformed from one configuration into another, while also allowing for rotation, and allowing roller systems to be used. Many of the current gin poles available are quite limited in how they can be used. In general, current gin poles are either very light-weight and portable, which sacrifice the maximum load they can hoist, or they can hoist large loads, with the loss of portability. In addition, many of the gin poles that are used in the industry do not technically meet all code requirements for the documentation provided when purchased. While many of them are adequately designed for their intended work, the proper documentation per code requirements leads to gray areas such as the lifting capacity, allowable lifting configuration, attachment to structure requirements, tiebacks requirements, etc.Docket No. P14510WO00 3

[0008] Additional issues with current gin poles exist. The maximum amount of load a gin pole can hoist is generally dependent on the hoist installation location. There are currently no gin poles with a hoist attached directly to it. In addition, gin poles are currently designed with load charts that either use a tag line, or no tag line, not both. Current gin poles do not have trolley systems to move loads laterally. Still further, most gin poles on the market only allow using slings to attach the gin poles to the structure, resulting in the gin pole being sloppy when using, adding more unpredictability to the overall system. Gin poles on the market also do not have wheels for transporting or moving from one point to another. Finally, most gin poles available take a great deal of time to hoist and install.

[0009] Thus, there exists a need in the art for systems and / or apparatus that overcome one or more of the issues presented, which include, but are not to be limited to systems and apparatus used in the construction industry, such as gin poles.SUMMARY

[0236] As will be understood, the present disclosure covers various aspects and / or embodiments of a multifunctional construction engineering device. Throughout this disclosure, the terms multifunctional construction engineering device, multifunctional construction device, multifunctional device, and MFD refer to the same disclosed device. The MFD may be used in a number of industries, including construction. The MFD according to at least some of the aspects and / or embodiments disclosed is designed to accept connections / insert attachments in multiple locations in multiple sides (each, or simultaneously) using slots (on one or more sides) independent of one another along the length of the multifunctional construction engineering device with internal integrated pin(s) (optionally, with springs) that can be locked in position, and multiple end connections for various interchangeable end connection options. All attachments for the MFD can be attached to and hoisted up with the MFD (does not require multiple picks for attachments associated with a given MFD).

[0237] The MFD is designed to be used in the telecommunication industry and / or construction industry, and / or any other industry. The MFD is highly dynamic by being able to configure into several different types of construction engineering device configurations toDocket No. P14510WO00 25 meet the user's application using engineered load charts and / or custom engineered calculations, depending on the application. Figs. 1A through 30C show a sample of a foursided equally spaced MFD model with associated parts / subassemblies. Fig. 1A shows an example first model multifunctional device, where the first model MFD has four equal sides. In embodiments, the multifunctional device may have four equal sides, three equal sides and one different side, two pairs of equal sides, two equal sides and two differing sides, or each side of the multifunctional device is different. The material shapes and properties for all components may vary depending on the model. It should be noted that for some MFD Models, the embodiments of the MFD may also be configured with different layout(s) on each side / face of the MFD as will be discussed further herein.

[0238] The MFD may be used by itself, or multiple MFD's can be connected / combined with other MFD members, regardless of MFD model, to create custom construction engineering devices, or to create standard construction engineering devices using the integrated pin plate subassembly, and / or spring-loaded (slot and / or end cap) pin plate subassembly slot system(s). Many embodiments of the MFD are configured so that the same layout is present on each side / face of the MFD, allowing the MFD to be used in any direction, rather than being limited to be used on only one side, like is common in most other construction engineering devices available. This results in an almost unlimited number of configurations to meet the users' needs. In addition, it allows different sides to be used each time, preventing significant wear and tear on individual components.

[0239] The MFD is designed to allow the user to use one, or multiple, or all slots for increased functionality. The MFD will also be able to be used for fall protection (fall hazard elimination, passive fall protection, active fall restraint, fall arrest system, etc.), holding tools, temporary loads, or other attachment needs while still being able to function for its intended use for the associated configuration.

[0240] The MFD universal (slot and / or end cap) insert attachment(s) will make it even more dynamic by allowing the MFD to rotate and / or angle into various directions to meet the users' needs. The MFD is not limited to just one application since it can be configured into several different types of configurations.Docket No. P14510WO00 26

[0241] In embodiments, the MFD models use pin plate subassemblies. There are two primary types of pin plate subassemblies: end cap pin plate subassemblies and slot pin plate subassemblies. Both types of subassemblies lock in insert attachments. The end cap pin plate subassemblies are generally used for attaching end cap insert attachments to the MFD. The slot pin plate subassemblies are generally used for attaching slot insert attachments to the MFD. The term pin plate subassembly may be used further herein to explain one, or both types of these subassemblies. Both types of pin plate subassemblies use similar components, and function similarly. These pin plate subassemblies will be discussed further herein.

[0242] In embodiments, the MFD models use insert attachments. There are two primary types of insert attachments: end cap insert attachments and slot insert attachments. Both types of insert attachments lock into the MFD using (slot and / or end cap) pin plate subassemblies. The end cap insert attachments are generally locked into the MFD using the end cap pin plate subassembly(s). The slot insert attachments are generally locked into the MFD using the slot pin plate subassembly(s). The term insert attachment may be used further herein to explain one, or both types of these attachments. These insert attachments will be discussed further herein.

[0243] In embodiments, the MFD model will have a naming convention that starts with the MFD Model primary name followed by the MFD Composite Designation resulting in a unique Model name. Generally, all MFDs that have the same model primary name will be the same with exception of the materials (material type, properties, etc.) used for the various part(s) / and / or subassemblies for the MFD model. The composite designation is used to group all the various materials used for the various part(s) and / or subassemblies. For example, Figs. 1B-1D show example composite designations A-C, respectively. All of the materials used in the MFD may be all the same material type or different. For example, the materials used by the MFD may include, but are not limited to, metals (i.e., aluminum, steel, titanium, or the like) composite materials (i.e., plastic composites, wood composites, or the like), fiberglass, or other similar construction materials. For these examples, the sheath, internal fixed structural members (IFSM(s)), and end caps utilize different types of materials depending on the composite designation selected. It should be noted that this example only covers the sheath, IFSM's, and end caps for a change in materials depending on the composite designation selected, but any MFD part and / or subassembly may also have varying materials depending on the composite designation selected.Docket No. P14510WO00 27

[0244] It should be noted that, while certain aspects and / or embodiments of MFDs are shown and described herein, these are not to be limiting. For example, it should be appreciated that the shape, width, or layout of any of the MFDs can be varied. In addition, in a single MFD, the same or different face widths on perpendicular faced may be utilized, but generally, opposite sides of a rectangular MFD will have similar face widths.

[0245] The figures described herein also may show four different exterior sides for a MFD model. In some embodiments, each exterior side of a MFD is considered a face and each face has a unique designation, in which the first letter of the designation is for the Face and is indicated by the letter F and the second letter of the designation is used to indicate which face it is. For example, the first face (F) of the MFD is designated by the letter A, the second face (F) is designated by the letter B, and each sequential face (F) in a clockwise direction is designated by the next sequential alphabetical letter. As shown in Fig. 3B, the cut section calls out 4 different face designations which are shown in this figure on the middle interior of the sheath on each side, and are shown as FA, FB, FC, and FD. In this example FA stands for Face A, FB stands for Face B, FC stands for Face C, and FD stands for Face D. Generally, the naming of the MFD faces, regardless of model, will follow these unique designation rules, but is subject to change.

[0246] Further, in some embodiments, the MFD model figures described herein may show all four exterior sides / faces in a top-down view. In these embodiments, the section between the center of a slot to the next adjacent slot (next available slot at same elevation) is considered a zone, and each zone is considered a quadrant. Each zone of a MFD has a unique designation. The first letter of the designation is for the zone is indicated by either the letter Z, or the letter Q. The second letter of the designation is used to indicate which zone it is. The first zone (Z or Q) of the MFD is designated by the number 1, the second zone (Z or Q) is designated by the number 2, and each sequential zone (Z or Q) is designated by the next sequential number in a clockwise direction. In addition, the first zone (Z or Q) is between the first (FA) and second face (FB), and the second zone (Z or Q) is between the second (FB) and third face (FC), and this pattern repeats as needed for each zone. For example, as shown in Fig. 3B, the cut section calls out 4 different zones (shown as Q) designations which are shown in this figure on the interior corner of the sheath for each corner, and are shown as QI, Q2,Docket No. P14510WO00 28Q3, and Q4. In this example QI stands for Quadrant #1 (For Zone #1) and is located between face A (FA) and face B (FB), Q2 stands for Quadrant #2 (For Zone #2) and is located between face B (FB) and face C (FC), Q3 stands for Quadrant #3 (For Zone #3) and is located between face C (FC) and face D (FD), Q4 stands for Quadrant #4 (For Zone #4) and is located between face D (FD) and face A (FA). Generally, the naming of the MFD zones, regardless of model, will follow these unique designation rules, but is subject to change.

[0247] Figs. 2A and 2B show a first model (all equal sides) multifunctional device, similar to Fig. 1. Fig. 2A shows faces / sides A and C of the MFD and Fig. 2B shows the perpendicular faces / sides B and D of the MFD. Each of these faces / sides in Figs. 2A and 2B show two main elevation sections of the MFD: an end slot section, and a non-end slot section. The end slot section on a face is the section that shares the first or last slot elevation / location on the MFD for the associated face. An end slot section on a face is considered from the end of the MFD (not including end cap top) to the midpoint between the first two slots from the associated end of the associated face. The non-end slot section(s) on a face are all other slot sections between the end slot sections on the associated face. A non-end slot section face that is adjacent to the end slot section on the same face is considered between the midpoint of the first two slots from end and midpoint between the second and third slot from same associated end of the same associated face. A non-end slot section face that is not adjacent to the end slot section on the same face is considered between the midpoint of the associated slot and next upper slot, and the midpoint of the associated slot and next lower slot on the same associated face. This four-sided equally-spaced first model MFD shares the same slot elevations, slot components, and slot sizes for each face of the MFD (See Fig. 1, 2A, and 2B) for both the end and non-end slot sections. MFD models may vary and have different slot elevations, and / or slot components, and / or slot sizes for an end slot section, which will be discussed further herein.

[0248] Fig. 2A has two callouts for 2 different elevation sections cuts through the MFD, an end slot section which is shown in Figs. 3A-3B, and a non-end section which is shown in Figs. 5A-5B, to better explain the internals of the MFD. Fig.2B similarly calls out a section cut for an end slot section, which is shown in Figs. 7A-7B, and a section cut for a non-end slot section, which is shown in Figs. 9A-9B. Figs. 3B, 5B, 7B, and 9B show top- down internal views of theDocket No. P14510WO00 29 multifunctional devices at the end slot sections (Figs. 3B and 7B) and the non-end slot sections (Figs. 5B and 9B). Perpendicular to Figs. 3B, 5B, 7B, and 9B, side-view elevation cuts are also shown in Figs. 4A-4C, 6A-6C, 8A-8C, and 10A-10C.

[0249] The end slot sections shown in Figs. 3A and 7A and the non-end slot sections shown in Figs. 5A and 9A illustrate the similarities and differences between the face A / C and B / D. Notably, as this MFD model has all the same sides, thus the slots and holes in the sheath of the MFD, and placement of the pins are substantially the same. Yet, the orientation of the slot locker and engagement pins on the faces differ such that on faces A and C the slot locker is slightly above the placement of the engagement pin which may be centered on the slot and on faces B and D the inverse is correct.

[0250] Figs. 11A-30C dissect the first model multifunctional device shown in Figs. 1A-10C. The parts and subassemblies of the first model multifunctional device are discussed below. Further detailed discussions of these parts and subassemblies are discussed in their respective sections of this description below and in reference to further Figs. 30E-109C.

[0251] Figs. 11A-11C show the exterior sheath of a first model multifunctional device. Fig. 11A shows the exterior sheath as a substantially square cover, which conforms to a substantially square MFD interior. The sheath protects the internal components of the MFD and has holes for the pins which secure components (subassemblies and / or insert attachments) to and in the MFD. As discussed above, this MFD model has the same slot elevations and sizes for each face of the MFD, as can be seen in Figs. 11B (showing face A / C) and 11C (showing face B / D), but not all MFD models may have the same slot elevations and / or sizes for every face. For example, an MFD may be rectangular with two wider sides that are substantially similar to each other, and two narrower sides that are substantially similar to each other, but different from the wider sides. Figs. 11B and 11C show a schematic view of the face of a first model MFD, and highlighting the end sections on either end of the MFD. As discussed above, this first MFD model differs in that the slot locker and engagement pins are slightly above or below each other depending on the face of the MFD, which can be clearly shown in these figures.

[0252] In some embodiments, the sheath has external markings or text near or surrounding the pins and / or slots. In some aspects, "Auto Engage" text is around the knob of theDocket No. P14510WO00 30 engagement pin(s) with arrows, and "Lock" text is shown around the knob of the slot locker (or plunger pin) to aid the user in interacting with the correct knob pin. In other aspects, the slots may be designated by the face and number slot on the face of the MFD. For example, the first letter (f) signifies the face of the MFD and the number after it (#) signifies the slot number. The slot numbers are sequential from left to right when used horizontally, and from top to bottom when used vertically. If the MFD is used with end #1 at bottom, and end #2 at top, or in the opposite direction, the first slot at the top will always be the same slot designation. For example, if the MFD has 7 slots on a face and used vertical, and used on face A, then the first slot designation at top will be Al and the last slot location (at bottom and on same face) will be A7, regardless of if end #1 is at top or bottom. The slot designation is located above and below each slot on opposite corners, and the text that is not upside down (angled or otherwise) is the slot designation.

[0253] Figs. 12A-13B show internal fixed structural members of a first model multifunctional device. Figs. 12A and 13A show example L-shaped internal fixed structural members and Figs. 12B and 13B show schematic drawings of each side of the L-shaped internal fixed structural members, separated into each end section and a middle section. The internal fixed structural members provide stability internally for the MFD. In embodiments, the internal fixed structural members are L-shaped, C-shaped, l-shaped, orthe like. In some embodimentsthere may be four, three, two, or one internal fixed structural member. In some embodiments, the orientation and placement of the holes of the internal fixed structural member may be different than those shown in these figures. Different placements of holes may be dictated by subassemblies and insert attachments of the MFD models further described herein.

[0254] Figs. 14A-17B show exemplary pin plate subassemblies. As discussed above, there are two primary pin plate subassemblies, end cap pin plate subassemblies and slot pin plate subassemblies. The end cap pin plate subassemblies interact with end caps inserts at the ends of an MFD model. Figs. 14A and 15A show an assembled end cap pin plate subassembly. Figs. 14B and 15B show schematic views of the end cap pin plate subassembly and parts of the end cap pin plate subassembly. The end cap pin plate subassembly generally comprises an end cap pin plate, an end cap slot pin (or end cap slot pin), an end cap locking pin, and indentations and / or holes for guiding springs and / or rods that may guide the pin plates. In an aspect, theDocket No. P14510WO00 31MFD does not include indentations and / or holes for springs and / or rods. In further aspects, the MFD does not include an end cap locking pin. In embodiments, when an end cap insert is to be inserted at the end of an MFD model, a user would disengage the slot locker pins and engagement pins at the end of the MFD model to then insert the end cap insert and secure the end cap insert by screwing in (or engaging) the engagement pins, which would secure into end cap slot pin, and further secure by screwing in (or engaging) the slot locker pins, which would perpendicularly secure the end cap locking pin. Further embodiments and discussion of subassembly part interactions are discussed below.

[0255] The slot pin plate subassemblies interact with slot inserts at the slots of the sheath of an MFD model. Figs. 16A and 17A show an assembled slot pin plat subassembly. Figs. 16B and 17B show schematic views of the slot pin plate subassembly and parts of the slot pin plate subassembly. The slot pin plate subassembly generally comprises a slot pin plate, at least one slot pin, a slot locking pin, and indentations or holes for guiding springs and / or rods for guiding the pin plates. In an aspect the pin plate subassembly does not include a locking pin. In another aspect, the pin plate subassembly does not have indentations and / or holes for springs and / or rods. In embodiments, the slot pin plate subassembly operates in a similar fashion to the end cap pin plate subassembly, with disengaging the slot locker pins and engagement pins at the slot to be used, inserting a slot insert, and engaging the engagement pin, which would secure into a slot pin , and engaging the slot locker pin, which would perpendicularly secure the slot locking pin.

[0256] In embodiments, additional subassemblies are used in conjunction with the pin plate subassemblies to further secure components or parts of the pin plate subassemblies such as an engagement pin plate subassembly and a lock pin plate subassembly. Figs. 18A-B show an engagement pin plate subassembly that generally comprises an engagement pin plate with guide rods. In embodiments, the engagement pin plate contains holes to allow the engagement pins to pass through, which creates added structure to secure the engagement pins when they are engaged and disengaged. In further embodiments, the engagement pin plate has guide rods, which can be used as spring guide rods for a pin plate subassembly that utilizes springs, and / or can be used as further internal structural support for the pin plate subassemblies of the MFD model.Docket No. P14510WO00 32

[0257] Similarly, Figs. 19A- 19B show a lock pin plate subassembly that generally comprises a lock pin plate with guide rods and a bonded slot locker nut. In embodiments, the lock pin plate subassembly contains slot locker nuts and / or threaded connections that are bonded to the lock pin plate to allow the slot locker pins to screw into when disengaging, and through when engaging, which creates further added structure to secure the slot locker pins. In further embodiments, the lock pin plate has guide rods, which can be used as spring guide rods for a pin plate subassembly that utilizes springs, and / or can be used as further internal structural support for the pin plate subassemblies of the MFD model.

[0258] Example views of slot locker, engagement pin, t-handle engagement pin, bearing bolt, bearing washers (clipped, lock, and standard), and bearing nut engaging the components of the MFD are shown in Figs. 20A-20H. In embodiments, the slot locker passes through the sheath of the MFD to open or close (lock or unlock) the slot / end cap by perpendicularly interacting with the slot locking pin / end cap locking pin. Similarly, in embodiments, the engagement pin passes through the sheath of the MFD to engage or disengage the slot pin plate subassembly by screwing into (to disengage) or fully through (to engage) the nut of the slot pin plate. In some aspects, the engagement pin may engage or disengage via a spring loaded system instead of screwing directly into the system (via a nut of the pin plate). Generally, the slot locker will be on the horizontally opposite side of the slot then the engagement pin, when viewing the MFD vertically. It should be noted that some models may not have a slot locker or engagement pin associated with one, multiple, or all slots. For these models, a hole would not be added to the sheath for the associated slot(s). The slot locker and engagement pin will be discussed further herein.

[0259] Figs. 21A-E are views of springs and spring guides for pin plate subassemblies. In some embodiments, springs are used to provide compression or tension between the pin plate subassemblies and the sheath or internal fixed structural members of the MFD. In some aspects, the springs are compression springs, tension springs, or the like. In other aspects, other biasing members may be included, or no biasing members are included. The spring guides, shown in Figs. 21D and E, may or may not be parts included in pin plate subassemblies. The spring guides secure springs around the circumference when used with a pin plateDocket No. P14510WO00 33 subassembly. Springs and spring guides, in relation to the pin plate subassemblies, are further discussed below.

[0260] Furthermore, as shown in previous figures, all the internal components associated with a slot for a non-end and end slot section are the same for this MFD first model. The main difference between the non-end and end slot sections for this MFD model are bearing plates, and internal components or associated hardware required for the end cap.

[0261] Figs. 22A-23B show bearing plates used in a MFD model. The bearing plates used between the non-end and end slot sections for a MFD model may be different than the bearing plates between non-end to non-end slot sections. In addition, the bearing plate used for the last slot location on a face will generally use the end cap as a bearing plate when the top of the slot on the MFD end side is at the same elevation as the bottom of an end cap (portion of end cap directed toward middle of MFD) on the same associated side (See e.g., Fig. 4A). If this is not the case, then the bearing plate on the end side of the end slot section will be similar to the bearing plates being used between the non-end to non-end slot sections, which are shown in Figs. 22A and 22B. The addition of notches on the edge of the bearing plates like those shown in Figs. 23A and 23B may be required for compatibility with splice plate(s) and / or end cap reinforcement plates, which will be discussed further herein.

[0262] Figs. 24A-26B show example interchangeable end cap inserts, or end caps, used in a MFD model. According to MFD models discussed herein, the end cap insert may be compatible with the internal structure of the MFD model. In some exemplary embodiments, the end cap inserts may be four-sided as shown in Figs. 24A and 24B, or two-sided as shown in Figs. 25A and 25B. Further, the end caps may have at least two sides or at least 6 sides. As shown in Figs. 24A-26B, the end caps have a side #1 and a side #2. In some embodiments, the end cap may have at least one side being an end cap insert, a plug or end cap plate. In some embodiments, the end cap has a plate between two end cap insert sides, as shown in Figs. 26A and 26B.

[0263] It should be noted that, while certain aspects and / or embodiments of MFDs are shown and described herein, these are not to be limiting. For example, it should be appreciated that the shape, width, or layout of any of the MFDs can be varied. In addition, in a single MFD, the same or different face widths on adjacent faces may be utilized. Throughout this description,Docket No. P14510WO00 34 various exemplary MFD models are discussed and are shown in the figures to provide example structures and connections of an MFD model, which are not meant to be limited to these shown models. Previous figures have referred to a first exemplary MFD model, wherein all the faces / sides are the same. In further figures, a second, third, and fourth exemplary MFD model is considered. In embodiments, and as further shown and discussed herein, a first MFD model is square and has 4 similar sides, a second MFD model is rectangular and has two pairs of similar sides, a third MFD model is square-shaped, and a fourth MFD model is squareshaped. It is contemplated herein that an MFD may not be limited to only the four MFD models shown and discussed below, rather, the descriptions allow for an understanding of the connections and interactions between the components of the multifunctional device.

[0264] For example, Figs. 27A-27C and 28A-28C show a MFD second model for a non-end slot section for a MFD model that is rectangular and utilizes tension springs, including sectional views from the top and interior sides of the device. These are shown as rectangular in construction, but the MFDs can generally take any geometric shape (e.g., round, rectangular, square, etc.). Figs. 27A and 28A show slot pins in a disengaged configuration with the slots or channels open. Further, Figs. 27A and 28A show a 4-sided MFD in that there are four quadrants with the slots between the quadrants to allow for connection in four places. However, as will be understood, in some embodiments the MFD is 2-sided, in that there are two slots. Fig. 29 shows a MFD third model and Figs. 30A-30C show a MFD first model. The MFDs shown in these figures includes a sheath. As shown in the figures, there are various apertures, slots, and / or channels in the housing for interaction with the components of the MFD and attachments thereof. Further shown in Figs. 29 and 30A, the MFDs comprise end caps inserted at either end of the sheath.SHEATHING

[0265] The multifunctional device comprises an exterior sheath / outer housing, which is shown in Figs. 30D-30H. The exterior sheath may also be referred to as an outer housing, a sheath, an exterior shell, and / or a shell, all of which are the same embodied component of the MFD. In embodiments, the sheath may be substantially shaped as a square, round, triangular, or rectangular exterior shell / sheath surrounding the MFD. In preferred embodiments, the sheath is square or rectangular. The sheath may comprise at least oneDocket No. P14510WO00 35 cutout slot(s) along the length of the member, the amount and size of which are dependent on model, to allow attachments to be inserted therein. The sheath may also comprise various holes through the sheath to allow the engagement pins and plunger pins of the MFD to pass through. The exterior shell / sheath functions as the primary shaft of the device and as a sheath to protect the inner mechanisms. The slots are used for accepting connections or combining MFD's together. One slot, or multiple slots can be used at the same time to allow the MFD to be configured into an almost unlimited number of configurations. As noted, the slot heights, widths, and spacing varies according to model. In addition, the sheath length, size, and properties (material composition) can vary depending on the model.

[0266] The sheath may be configured to allow reinforcement members to be connected to it. The holes in the sheath wall may or may not be threaded depending on the MFD Model. In some embodiments, the MFD models have reinforcement members associated for each face for one, or both ends of the MFD, with which reinforcement holes would be added to the sheath for the associated end(s) and / or associated faces. In an aspect, Fig. 30D shows a sheath for a first model MFD that has reinforcement holes for reinforcement members, such as splice plate(s) / member(s), MFD reinforcement member(s), and end cap reinforcement member(s) / Subassembly(s). Some MFD models may not allow reinforcement members to be added using reinforcement holes, in which case these reinforcement holes will not be added into the sheath for these external attachments. Figs. 30E, 30F, and 30G are additional examples of sheaths that have MFD reinforcement holes for all faces, and Fig. 30H is an example of a sheath that does not have reinforcement holes on face A.

[0267] The sheath may be configured with through holes. Figs. 30E, 30F, and 30G show examples of sheaths with through holes located between each slot and centered on each face of the MFD, and Figs. 30D and 30H do not have through holes in the sheaths. Some MFD models will have through holes added to the sheath. These through holes are additional holes through the MFD Sheath in non-slot locations to allow bolts / pins / rods / coil rods, etc. to pass through the Sheath wall between / within the internal fixed structural members and generally connected through and behind the opposite Sheath wall with backer connection plates and / or, washers and nuts. The through holes can be used for additional connection options to the MFD. An example of such a connection would be a two-sided formwork system in whichDocket No. P14510WO00 36 the coil rod goes through the through holes of one MFD, and spans through the concrete zone, and attaches to the second MFD on the opposite side with the coil rod projecting through the through hole(s) with washer(s) and nut(s) attached on the backside of the MFD Sheath wall.

[0268] Slot opening sizes and locations may vary along the length of the MFD on some MFD models and may not be at same elevation on one, multiple, or all faces. Examples to help illustrate this are shown in Figs. 30E-30H. The internal pin plate subassembly(s) still functions the same as other models. It should also be noted that the slot heights may vary on the same face of the MFD (See e.g., Figs. 30F-30H).

[0269] In some embodiments, the MFD models will be equally spaced and all faces, and all slot elevation same on all faces for the same associated slot size. In addition, some MFD models will repeat this criteria one or more times for a different slot size. This type of MFD model can be connected linearly while maintaining the same spacing, and the face of a first MFD, can be aligned with any face and any size second MFD. In addition, end #1 of this type of MFD model can be connected to either end #1 or end #2 of the same MFD model. Fig.30C is an example of a MFD model that is equally spaced and all faces, and all slot elevation same on all faces for the same associated slot size, and this criteria repeated for another slot size. In other embodiments, the MFD models will not be equally spaced with differing faces. Fig. 30G is an example of an MFD model that has unequally spaced slots for the same slot size, and with more than one slot size on face A of the MFD. Fig. 30H is another example of an MFD model that has unequally spaced slots for the same slot size, and with more than one slot size on face A of the MFD.In some embodiments, MFD models do not use slot lockers and / or plunger pins for locking one, multiple, or all slots closed, in which case holes will not be added into the sheath for these associated components in the associated slot location. Fig. 30B is an example of a MFD sheath that does not have holes for slot lockers and / or plunger pins on face B, Fig. 30G is another example that does not have holes on all faces, and Fig. 30H is another example that does not have holes for some of the slots for face A.

[0270] Figs. 31A, 31B, and 31C show a closeup perspective view of the slot portion of the MFD. These figures show slot locker(s), and engagement pins on the outer housing of theDocket No. Pl 451 OWOOO 37MFD as shown. For example, and as shown in these figures, each slot has two external knobs / handles (projecting out of the exterior of the sheath) associated with it. In Fig. 31A, showing face A of a first model MFD, the upper knob shown to the right of the slot is the engagement pin which is used to engage or disengage the slot pins from the slot on the closest perpendicular face to allow the user to install or remove inset attachments into the slot. The lower knob shown to the left of the slot is the slot locker knob / handle and is used to lock the slot open and / or closed. It should also be noted that the slot locker (or plunger pin) may be higher or lower than the engagement pin on the same face for the same associated face, depending on which MFD model is being use, how the MFD is oriented and if end #1 is considered the top, or if end #2 is considered the top.

[0271] Both knobs are shown resting against the MFD exterior sheath wall when slot pins are engaged, as can be seen in Fig. 31A. The engagement pin knob / handle will either rest against the exterior sheath wall, as shown in Fig. 31A, or against a spacer or marked with an indicator, such as a colored zone on the pin, at the interface between the knob / handle of the pin and sheath wall, as shown in Fig. 31C, to indicate when fully locked.

[0272] Moving to Fig. 31B, a slot insert attachment may be positioned in a slot of a sheath / housing for the MFD model. The slot insert attachment can be securely held in place by engaging the engagement pin after the slot insert attachment has been inserted into the associated slot. In some embodiments, the MFD has a pin plate subassembly that utilizes a locking pin and to insert a slot insert attachment, a user must first release the slot locker by turning the slot locker counterclockwise until released from the lock position (or plunger pin released into un-lock position). Once this is completed, the engagement pin can be disengaged to open the slot, in which slot insert members or attachments can be inserted into the open slot. It should be noted that the overall slot plate size, shape, and properties will vary depending on what the slot insert attachment will be used for, but generally the profile of the slot insert attachment within the slot will remain constant. This can be seen with several of the attachments shown further herein. To secure the slot insert attachment into the slot, the engagement pin can then be engaged by pushing the engagement pin connected to the slot pin plate into a closed position via a spring (or turning clockwise into the engagement pin nut, if no spring loaded system). Once the engagement pin has beenDocket No. P14510WO00 38 engaged, the slot locker can be engaged into the lock position (or plunger pin released into lock position). The slot (connection / insert) plate can then be removed from the MFD by unlocking the slot, as described above.INTERNAL FIXED STRUCTURAL MEMBERS

[0273] The multifunctional device comprises one or more internal fixed structural member. The internal fixed structural member(s) may be referred to in the singular or plural and as internal members, internal structural members, fixed structural members, or IFSM, which refer to the same component of the multifunctional device. Internal fixed structural member(s) fit inside the exterior sheath of the MFD and may have various holes for pins and bolts to pass through the internal fixed structural member(s). The internal fixed structural member(s) will provide places to mount the inner mechanisms / subassemblies of the MFD, for connecting the slot pin plate subassembly(s) and insert attachments after inserted into the MFD slot(s), for connecting the end caps, and may also add additional capacity to the MFD. The internal fixed structural member(s) are arranged internally so that their faces do not cross over the slot openings.

[0274] For example, Figs. 32A-34B show the internal fixed structural members arranged in a "cross pattern" for first, third and fourth MFD four-sided models, respectively. In some embodiments, the MFD is a four-sided square model, and the internal fixed structural members are generally all the same size. In other embodiments, the MFD is a four-sided rectangular model having two angles / bent plates would generally have longer legs (larger width), and two would generally have smaller legs (smaller width). Figs. 35-36 show two different MFD models, both configured with only two faces having slot openings. In this case, the internal fixed structural members are shown as two back-to-back internal fixed structural members (shown as two C-shaped channels, or back-to-back bent plates) separated by the bearing plates. This configuration results in an internal "I-beam" configuration. The figure illustrates how the structural members within the MFD can be changed without effecting the functionality of the MFD. Generally, the slot openings and all internal and external mechanisms remain unchanged for each associated slot opening.

[0275] In embodiments, MFD models have the internal fixed structural members arranged such that the slots are open from one face of the sheath to the opposite face of the sheath.Docket No. P14510WO00 39In these embodiments, insert attachments that may be inserted into the slot will be connected using the first slot pins encountered, while other insert attachments will extend to the slot on the opposite side of the MFD from where inserted and will be connected by the first slot pins encountered, or the second slot pins encountered on the opposite side, or both the first slot pin(s) encountered and second slot pin(s) encountered on the opposite side for the associated slot to increase available working load limits / available capacity.

[0276] Figs. 34A and 34B show the internal fixed structural members for a tension spring plate system for a portion of a non-end slot section of a fourth model MFD. Interior fixed structural members for the tension spring plates will be similar to those used for compression spring plates with the exception of having additional holes through the fixed structural member (shown as angle / bent plate) to allow the springs to pass through and may have different hole locations for the bearing plate bolts to pass through when bearing bolts are used to connect the internal fixed structural member(s) together.

[0277] The quantity of holes in an Internal Fixed Structural Member(s) (IFSM) is dependent on the parts that enter or pass through it. Some MFD models may not have holes in the internal fixed structural members for the bearing plates, and instead the bearing plates may be bonded (e.g., welded) directly to the structural members. In addition, some models may not have holes for guide rod(s) for the pin plate subassembly(s) and some models may have holes for a tension spring to pass through. The quantity of holes in the side of an IFSM for the slot pins to pass through will match the quantity of slot pins that pass through the IFSM on that same associated side and is not dependent on the engagement type (Compression Springs or Tension Springs or no springs) used for the pin plate subassembly(s). The quantity of holes in the side of an IFSM for the guide rods will match the quantity of guide rods that projects into or through the same associated side of the IFSM. The quantity of holes in the side of an IFSM for the bearing bolts(s) will match the quantity of bearing bolt(s) that pass through the same associated side of the IFSM.BEARING PLATES

[0278] The multifunctional device comprises one or more bearing plates. Examples of bearing plates, and bearing plate subassemblies, are shown in Figs. 37-42. In embodiments, each slot opening has two bearing plates associated with them, one directly above and one directlyDocket No. P14510WO00 40 below each slot, which are attached between the interior fixed structural members (shown as angles / bent plate throughout the figures). These bearing plates are used to tie the interior fixed structural members together, to provide support for the inserted attachments, and to provide a guide for attachments inserted into the MFD. The bearing plates may vary in size or thickness depending on model, material composition, as well as bearing bolt quantity, size, and location. In some embodiments, the bearing plates may be bonded (e.g., welded) to an interior fixed structural member instead of using bearing bolt(s). In some aspects, there are no bearing bolt holes in bearing plates for models where the bearing plates are bonded to the structural members.

[0279] A single bearing plate may be used below or above multiple, or all slot opening location for the same slot elevation. Figs. 37-39 show examples of bearing plates utilized for slot opening locations in first and third exemplary MFD models. In some embodiments, there may be one bearing plate used for a 4-sided MFD model at the same elevation associated with one, two, or four slots. In further embodiments, a bearing plate may be used in some MFD models for two vertical adjacent slot locations, where other MFD models may use two separate bearing plates between the upper and lower slot locations.

[0280] Fig. 40 shows the bearing plates for a fourth MFD model that utilizes tension spring plates. The bearing plate quantity and installation location for an MFD that utilizes tension spring for the slot pin plate subassembly is similar to a MFD that utilizes compression springs for the slot pin plate subassembly, which can be seen in Fig. 38. The difference is that the MFDs that utilize tension springs have an additional hole through them for the tension spring to pass through, and there are two different types (different hole patterns, and different plate height) of bearing plates required. The difference in the hole pattern between the left and right bearing plates is necessary for spacing / interference reasons for MFD models that utilize tension spring.

[0281] In some embodiments, MFD models that utilize an internal reinforcement structural member, such as a coil rod, on the interior corner of the MFD Sheath, the bearing bolts may project to the internal reinforcement structural member. In other embodiments, bearing plates below an end cap slot are similar to bearing plate(s) used for the typical non-end slot section but may have a profile cut out of the side of the bearing plate for splice or reinforcingDocket No. P14510WO00 41 pins / bolts. In further embodiments, MFD models that do not have equal slot spacing along the length of the MFD, the end cap may or may not be used as bearing plates.

[0282] Fig. 41 shows the location and usage of bearing bolts for a non-end section of a MFD that uses a compression spring loaded slot pin plate subassembly system. For some models, bolts will be used to connect the internal structural member(s) (shown as angle / bent plate) and bearing plates together. For each bearing plate that is connected using bolt(s), each bearing plate will have a minimum of one bolt per bearing plate, however, bolts may be replaced with welds or other bonding methods for some models. Note that the bearing bolts are arranged and oriented differently for tension spring systems when compared to the compression systems (see e.g., Fig. 42). For example, the third hole, as shown in Fig. 40, is to allow a tension spring to pass through the bearing plate.PIN PLATE SUBASSEMBLIES

[0283] The multifunctional devices may include one or more pin plate subassemblies. The one or more pin plate subassemblies of a multifunctional device may comprise end cap pin plate subassemblies and / or slot pin plate subassemblies. In addition, the pin plate subassemblies may interact with engagement pins and / or slot lockers.

[0284] Generally, all insert attachment(s) can be locked into the MFD using the associated (end cap or slot) pin plate subassembly(s). These insert attachment(s) can be used to connect external attachments to, or to connect the MFD's together in various orientations to allow the MFD to be configured into an almost unlimited number of different types of configurations. Two sided inserts can be angled vertically, horizontally, or have a rotational angle to meet the user's configuration needs.

[0285] Fig. 43 generally shows a first model MFD with the sheath removed. Similarly, Fig. 44 generally shows a third model MFD with the sheath removed. These figures show many of the various internal components, including the internal fixed structural members, slot openings, engagement pins, engagement pin plate subassemblies, slot locking pins, lock pin plate subassemblies, end cap pin plate subassemblies, slot pin plate subassemblies, end cap subassemblies, bearing plates, and miscellaneous hardware (bolts, nuts, washers, pins, etc.). The pin plate subassemblies (end cap and slot), along with engagement pins, slot locking pins,Docket No. P14510WO00 42 and optional engagement pin plate subassemblies and slot locking pin plate subassemblies are broadly discussed below and in reference to the figures.

[0286] Generally, a pin plate subassembly is used for engaging or disengaging pins to lock an end cap into the end, or a slot insert into the slot opening, of an MFD. Generally, a pin plate subassembly includes a pin plate, slot pin(s), locking pin(s), and pin engager nut or threaded connection. The locking pin(s) of a pin plate subassembly are distinct from the slot locker and / or the engagement pin. In some embodiments, the MFD may have threads in the slot pin plate in lieu of using an engagement pin nut. The quantity of pins attached to a pin plate subassembly is one or more. The size and shape of a pin plate may vary to accommodate all the pin plate subassembly parts, and to allow slot pins associated with other pin plate subassemblies to pass by. A pin plate subassembly, regardless of an end cap pin plate subassembly or slot pin plate subassembly, is engaged with an engagement pin and an optional slot locking pin (or slot locker) that may lock the pin plate closed / open for adding insert attachments.

[0287] In embodiments, a slot portion of the outer housing of the MFD has at least two external knobs projecting out of the exterior of the sheath associated with the slot. As shown in the figures herein, one knob is the engagement pin which is used to engage or disengage the slot pins from the slot on the perpendicular face to allow the user to install or remove attachments into the slot. The second knob is a slot locker which is used to lock the slot open or closed. The slot locker may or may not be included on the MFD. Both knobs rest against the MFD exterior sheath wall when slot pins are engaged, and in a locking position. The slot locker also rests against the sheath wall when the slot is in the open position (to allow attachments to be inserted). The purpose of an optional slot locker is to provide another safety feature that when used, will keep, along with the springs, the pin plate assembly closed during work. It also serves as a user-friendly feature in that the user will be able to pull on the engagement pin to open the pin plate assembly, then engage the slot locker back into the locking position to lock the pin plate assembly in the open position. This will allow the user to insert attachments more easily into the associated slot.Docket No. P14510WO00 43ENGAGEMENT PIN

[0288] The main function of the engagement pin is to lock slot insert attachments within the slots of the MFD, for locking in the end cap insert attachments to the end of the MFD, and for disengaging any insert attachments from a slot / end cap. The engagement pin is attached to the end cap pin plate subassembly and / orthe slot pin plate subassembly. When engaged with a slot insert attachment inserted into a slot (or end cap inserted into end of MFD), the slot pin(s) attached to the pin plate subassembly will project through the internal fixed structural members as well as the slot insert attachment (or end cap) that is inserted between the internal fixed structural members to lock in said slot insert attachment (or end cap insert attachment). When engaged without a slot insert attachment (or end cap insert attachment), the slot pin(s) project through the internal fixed structural members. When disengaged with a slot insert attachment (or end cap insert attachment), after all external attachments to slot insert attachment are removed, the slot pin(s) attached to the (end cap or slot) pin plate subassembly only project into the first encountered internal fixed structural member to allow the slot (connection) plate to be removed. When disengaged without a slot insert attachment (or end cap insert attachment), the slot pin(s) attached to the associated pin plate subassembly project into the first encountered internal fixed structural member only to allow the slot insert attachment (or end cap insert attachment), to be inserted into the slot opening (or end cap opening), or removed from the slot opening (or end cap opening).

[0289] The engagement pin knob / handle will either rest against the exterior sheath wall, against a spacer at the interface between the knob / handle of the pin and sheath wall, or the engagement pin will be marked with an indicator (like a colored zone on the pin) to indicate when fully locked. Each slot opening that utilizes an end cap pin plate subassembly (end slot section) or the slot pin plate subassembly (non-end slot section and / or end slot section) will have an engagement pin associated with it.

[0290] In embodiments, the engagement pin associated with a slot or end cap may be used with an integrated spring-loaded system, operated manually by pushing in or out on the engagement pin, or by threading in the engagement pin into a fixed nut (which would be attached to the pin plate.Docket No. P14510WO00 44

[0291] The engagement pin is generally installed, after the internal components and sheath of a MFD is fully assembled, by inserting the engagement pin through the hole in the sheath, and then turning / threading the engagement pin into the nut (or a threaded connection) attached to the pin plate subassembly. The shape, size, length and materials used for an engagement pin may vary depending on the MFD model. It should be noted that the engagement pins are required to open or close a slot, but once the slot is open (when using slot locker), or closed, the engagement pin may be added or removed. In some embodiments, the MFD uses an integrated spring-loaded system, the engagement pin after it has been engaged will keep the pin plate subassembly(s) in a locked position after it has been removed.

[0292] The engagement pin may also be attached to a nut attached directly to the sheath, attached to a threaded connection within the sheath, or attached to a threaded connection of the internal members within the sheath to engage or disengage a pin plate subassembly. In some embodiments, a spin nut / threaded connection would be added to the pin plate to allow the engagement pin to spin at the pin plate and allow a fixed nut / threaded connection to be used for engaging or disengaging the engagement pin.ENGAGEMENT PIN PLATE SUBASSEMBLY

[0293] As noted, to hold the slot and end cap pin plate subassemblies in place at the MFD, an engagement pin plate subassembly may be optionally used. The engagement pin plate subassembly is a plate with guide rods attached to it, and additional holes for the engagement pin to pass through. In some embodiments, an engagement pin plate subassembly and compression springs are utilized where the compression springs may be placed around the guide rods, and rest between the back side of the slot / end cap pin plate and the front side of the engagement pin plate. The engagement pin plate will rest against or will be attached to an interior wall of the sheath. In this embodiment, when used, the compression springs will generally be held in position using guide rods that are attached to the engagement pin plate. The compression spring may be placed directly behind the slot pins, or where space is available on the back side of the slot / end cap pin plate. If attached directly behind the slot pins, there will be two guide rods for each slot pin; one attached to the alignments spring plate and one attached and centered on the back side of each slot pin (see e.g., Figs. 47A, 47B). The total length of these two guide rods will be no more than what is required toDocket No. P14510WO00 45 disengage the slot pins fully from the slot. If the compression springs are not attached to the back side of the slot pins, then the guide rods will be attached to the engagement pin plate, and project through the (end cap or slot) pin plate (see e.g., Figs. 52A- 52B), and will project into the first interior fixed structural member(shown as angle / bent plate) to hold in position.SLOT LOCKER

[0294] The main function of the slot locker is to lock the (end cap or slot) pin plate subassembly in a closed position to provide another safety feature that will keep, along with the springs (for models that utilize this option), the pin plate subassembly closed during work. In some embodiments, the slot locker is a plunger pin that can be a retractable spring plunger, twist-to-lock retractable spring plunger, or similar pin that incorporates a spring. The nose of a retractable spring plunger can be retracted by pulling the knob / handle. The nose of a twist- to-lock retractable spring plunger can be locked into the retracted position by pulling on the knob and rotating it 90 degrees. The main difference between the slot locker and plunger pin is that the plunger pin may have a spring incorporated within it and is generally installed / threaded into the MFD when the MFD is assembled and does not need to be threaded into and out of a nut / threaded connection everytime it is used, unlike the slot locker is engaged or disengaged by threading into and out of the nut / threaded connection attached to the lock pin plate subassembly. The plunger pin and / or slot locker can either attach to a lock pin plate subassembly, or to a nut plate within the sheath that is shaped such that it can't rotate within the MFD (see e.g., Fig. 60). For some models, the slot locker (or plunger pin) can also be used to keep the slot open, and serves as a feature in that the user will be able to pull on the engagement pin to open the pin plate subassembly, then engage the slot locker (or plunger pin) back into the locking position to lock the (end cap of slot) pin plate assembly in the open position. This will allow the user to add insert attachment(s) more easily into the associated slot(s). The slot locker may not be available in some MFD models for one, multiple, or all slots. Removal of the engagement pin for the associated slots that do not have a slot locker after the insert attachments have been engaged with a spring-loaded pin plate subassembly system will also keep the associated slots locked in a closed / engaged position.Docket No. P14510WO00 46LOCK PIN PLATE SUBASSEMBLY

[0295] In some embodiments, the multifunctional device may comprise a lock pin plate subassembly which is used for attaching the slot locker to the MFD. The lock pin plate subassembly may have guide rods and nuts aligned with holes in the plate for the locker pins or plunger pins to attach to. In some aspects, the lock pin plate subassembly may use springs to keep the lock pin plate subassembly in place, which may be placed around the guide rods. In other aspects, the lock pin plate may be attached directly to the sheath wall to keep it in position in lieu of using spring(s). In some aspects, the guide rods of a lock pin plate subassembly may be placed through a hole of the lock pin plate subassembly. Further, in some aspects, nuts may be attached to the exterior of the sheath to be used instead of the lock pin plate subassembly to attach and secure the slot locker. The lock pin plate subassembly shape, material sizes and properties may change depending on MFD Model. In preferred embodiments, a lock pin plate subassembly may be molded out of one piece, but in some aspects the lock pin plate subassembly may be multiple pieces.PIN PLATE, SLOT PINS, LOCKING PINS, AND OPTIONAL PIN ENGAGER NUT

[0296] Generally, a pin plate subassembly includes a pin plate, slot pin(s), locking pin(s), and pin engager nut or threaded connection. The locking pin(s) of a pin plate subassembly are distinct from the slot locker and / or the engagement pin.

[0297] The end cap / slot pin plate may have holes in it for guide rods to pass through, to allow the pin plate to move freely over the guide rods. The pin plate(s) may also include notches. In some embodiments, the pin plate requires notches for all internal components for the slot pin plate to pass by the slot locker (or plunger pin), and slot pins for the adjacent pin plate subassembly. The pin plate subassembly may also be molded as one piece to the model requirements. A pin plate subassembly may be molded out of one piece or multiple pieces.

[0298] In some embodiments, the slot pin(s) are attached or bonded by welding, threading into, pressed fit, glued, or the like, to the pin plate. In embodiments, slot pins are tapered at the ends to guide the pins and allow them to enter the fixed internal structural member slot pin holes easier and tapered such that the pins get substantially full bearing against the fixed angles when in the fully closed position. Fig. 45 shows a cut section through the middle of a slot opening of a MFD when all slots are in the open position. The figure only shows theDocket No. P14510WO00 47 exterior sheath, internal fixed structural member, and slot pins, but shows how the tapered portion of the slot pin remains in the structural members (shown as fixed angle(s) / bent plate(s)) even when fully disengaged (slot in open position). The slot pins of a pin plate subassembly may be in a disengaged configuration with the slots or channels open, in an engaged configuration with the slots or channels closed, or a combination of both. One, multiple, or all of these slots may be used at the same time. Each face of the MFD at a given elevation may have a slot, and the total number of slot sides will vary depending on the model and can be of any quantity.

[0299] A lock pin may or may not be included on a (end cap or slot) pin plate subassembly. A pin plate subassembly that uses a lock pin may use it to lock a slot in the closed and / or open position. When a locking pin is included on a pin plate subassembly and when it projects out of the same side of the pin plate as the pins, the locking pin can be used to lock the slot pin plate subassembly open (See Q4 in Fig. 64). When a locking pin is included on a pin plate subassembly and when it projects out of the opposite side of the pin plate as the pins, the locking pin can be used to lock the slot closed (See Q4 in Fig. 63). It should be noted that some MFD models may or may not use lock pin(s) for one or more of the pin plate subassemblies associated with said model. The lock pins on an end cap pin plate subassembly, and slot pin plate subassembly function similar to each other. The locking pin may be attached or bonded to the pin plate via welding, threaded into, press fit, glued, or the like, to the pin plate(s), which will project a specified distance in front of, and / or behind the plate to allow slot pin(s) to be locked in the closed and / or open position. In embodiments, MFD that incorporates spring loaded pin plate subassemblies, locking pins can only lock inserts closed (engaged).

[0300] Optionally, slot pin plate subassemblies and / or end cap pin plate subassemblies may utilize a spring-loaded system to auto-engage the slot pins through the internal fixed structural members (and insert attachments when installed) by the incorporation of springs. The term auto-engage is considered the ability for the slot pins to enter and go through the internals fixed structural members and insert attachment for the associated slot elevation with the help of a spring-loaded system. The spring-loaded system is composed of either tension springs, or compression springs within the MFD. The difference between models that use the compression spring and tension springs will be discussed further herein.Docket No. P14510WO00 48

[0301] The MFD (end cap and slot) pin plate subassemblies may be engaged on some models by utilizing springs. When springs are used for these subassemblies, the spring size, length, and properties may vary for one, multiple, or all these subassemblies. The MFD pin plate subassemblies may or may not utilize spring guides when using springs. The spring guides will generally be used with, and installed around the guide rods, and are used to keep the springs aligned. When springs are used for these subassemblies, the spring guide size, length, and properties may vary for one, multiple, or all these subassemblies. Some models may not have these springs, in which case the engagement pin may be engaged / disengaged by pushi ng / pu I li ng on the engagement pin, or by turning the engagement pin by way of threads.

[0302] The pin plate subassemblies may have an engagement pin nut attached to each pin plate subassembly directly behind the middle slot pin. In other embodiments, MFD models will have threads in the slot pin plate in lieu of using an engagement pin nut.

[0303] When an end cap and / or slot insert is installed, the independent pin plate subassembly either engages (locks) an inserted (slot or end cap) insert attachment or releases (unlocks / disengages) said insert attachment. In some embodiments, springs are used to auto engage the pin plate subassembly into a closed position after the slot or end cap plate insert attachment is inserted and aligned with connection(s), and when the user releases the associated engagement pin. In other embodiments that have a locking pin, after the pin plate subassembly is engaged, the slot locker (or plunger pin) is engaged and perpendicularly rests behind the locking pin to lock the attachment into the slot (see e.g., Fig. 70). To release the attachment, the slot locker (or plunger pin) is disengaged, and the engagement pin is pulled outward by a user to disengage from attachment. Further, to hold the pin plate subassembly in an open position, the slot locker can be engaged again to lock the slot open using the same locking pin (on opposite side of plate; see e.g., Fig. 71). The slot and end cap pins are designed to fully disengage from the slot but not the first encountered internal fixed structural member (see e.g., Fig.45). This design is intended to be both ergonomic and with safety in mind to ensure that the slot pins do not become misaligned during normal device operation which would cause the pins to not engage attachments properly. Please note that auto engage may not always work, and users may be required to push, and / or maneuver pin plate assembliesDocket No. P14510WO00 49 by using the engagement pin to get the slot pins to engage into and through the insert attachment(s) and internal fixed structural members.

[0304] The end cap and slot pin plate subassemblies are further described below in reference to the figures.END CAP PIN PLATE SUBASSEMBLIES

[0305] End caps may be inserted at either end of the sheath of the multifunctional device. There are different types of interchangeable end caps that may be inserted into the MFD ends depending on the application and connection requirements, as will be described herein. In some embodiments, MFD models may also have end caps that are attached directly to the sheath. The end cap pin plate subassembly is used for attaching and locking in various interchangeable end caps and is located on the ends of the MFD (End #1 and End #2). The end cap pin plate subassembly is similar to the slot pin plate subassembly, but functions to lock the end caps to the internal fixed structural member(s) instead of locking in slot (connection) plates, or insert attachments described herein. An engagement pin is used to engage or disengage the end cap pin plate subassembly. Engaging the end cap subassembly with the end caps installed will lock in and securely hold the end cap(s) in place. In some embodiments, there may also be a keyway located on ends (end #1 and end #2) of an MFD for alignment of end cap.

[0306] In embodiments, there are one or more slot pin(s) of an end cap pin plate subassembly. Figs. 46A-46B show a first MFD model and is an example of a slot pin plate subassembly that utilizes only one slot pin, whereas the end cap pin plate subassembly shown in Figs. 47A and 47B is an example of a slot pin plate subassembly that utilizes two slot pins.

[0307] Figs. 46A and 46B show an end cap pin plate subassembly for a first model MFD with compressions springs and guide rods. In these figures, the guide rods are within holes of the pin plate, the springs are surrounding the guide rods, and being contained by indents in the pin plate. The guide rod(s) used for this end cap pin plate subassembly are not behind the end cap slot pins in this example. This end cap pin plate subassembly for this MFD model only uses one slot pin, with which the engagement pin would engage / disengage an end cap insert. Further, the lock pin is positioned on the exterior side of the pin plate, or the oppositeDocket No. P14510WO00 50 direction of the slot pins, allowing the slot to be only locked in a closed position by the slot locker.

[0308] Figs. 47A and 47B also show an end cap pin plate subassembly for a third MFD model also comprising compression springs and guide rods. In these figures, beyond having two slot pins instead of one, the guide rod(s) used for this pin plate subassembly are behind the end cap slot pins and the diameter of these rods will be less than the inside diameter of the springs, and the length will be such that the end cap slot pins can be fully disengaged from the slot. Figs. 48-51 show end cap connections for MFDs with compression springs. Figs. 48 and 49 shows the end slot section for a first MFD model and Figs. 50 and 51 show the end slot section for a third MFD model that both utilize a compression spring loaded (slot and end cap) pin plate subassembly and a locking system. The components, and operation for engaging and disengaging slot pins for an end cap pin plate subassembly is similar to the slot pin plate subassembly but may require a cotter pin (or another mechanical fastener or spacer) to keep the associated end cap slot unlocked. As shown in Figs. 48 and 50, the slot locker, or plunger pin, is used in these figures to lock the slots closed (lock the ends cap in place) to the MFD interior fixed structural member(s) (shown as angle / bent plate). The end cap pin plate subassembly for this model has compression springs directly behind the slot pins and uses two slot pins. Figs. 49 and 51 show the engagement pins and slot lockers fully engaged and locked in on all four faces. In these figures, the interaction of the slot locker with the locking pin and the engagement pin with the engagement nut of the pin plate subassembly can be clearly seen.SLOT PIN PLATE SUBASSEMBLIES

[0309] Moving now to slot pin plate assemblies. In general, the slot pin plate assemblies are used to engage or release insert attachments that are inserted into the slots. The slot pin plate assembly is generally comprised of a plate with slot pin(s), optional spring holes (for models with tension springs only), an engagement pin nut bonded to the pin plate (engagement pin screws into this nut after sheath is installed) and an optional locking pin that projects through the pin plate on both sides (used to interact with slot locker / plunger pin).

[0310] Figs. 52A and Fig 52B are isolated perspective views of the slot pin plate subassembly for a non-end slot section for a first MFD model that uses an internal compression springDocket No. P14510WO00 51 system for the associated slot(s). Figs. 52A and 52B show an example of a lock pin that can lock the slot closed but can't lock the slot open, as the locking pin is placed on the exterior side of the pin plate, or opposite side of the slot pins. Space constraints within the MFD sheath may limit the ability for a lock pin to be used to lock the slots open. The large pin with knob / handle shown vertically, above, and attached to the pin plate subassembly nut shown in Figure 52A and 52B is the engagement pin. Pulling on the engagement pin (after the slot locker or plunger pin is pulled and locked open for models that have this option) will release the associated slot pin(s) from the associated slot opening to allow the user to remove the associated slot insert attachment that is installed in the slot. Once completely disengaged, the slot locker (or plunger pin) may be engaged by the user to lock the slot in an open position for models that have this option available for the associated slot(s).

[0311] Figs. 53A and 53B show a slot pin plate subassembly for a non-end slot section for a third MFD model that similarly uses compression springs. In these figures, an engagement pin nut is bonded to the pin plate assembly directly behind the middle slot pin, which the engagement pin interacts. The slot pin plate of these figures also has holes in it for the guide rods to pass through, and to allow the pin plate to move freely over the guide rods. The slot pin plate of these figures additionally has a hole in it for the lock pin to go through, and projects a specified distance in front of, and behind the plate to allow slot pins to be locked in the open, or closed position. The spring plate may also be notched out, as shown in Fig. 53A for the plate to pass by the plunger pin. Figs. 54A and 54B shows a pin plate subassembly for a fourth MFD model where the pin plate is shaped to have additional holes near the ends of the plate to allow tension springs to pass through.

[0312] Figs. 55-57 shows cut section views for a non-end slot section with the slot pin plate subassembly(s) for a first MFD model with a compression spring plate system for the associated slot(s). These views show this MFD example model fully, or nearly fully assembled at this slot elevation. This includes the internal fixed structural members, engagement pin plate subassemblies with associated parts, lock pin plate subassembly(s) with associated parts, slot pin plate subassembly(s) with associated parts, bearing plate, miscellaneous hardware (bolts, nuts, washers, pins, etc.), etc. In embodiments, a first MFD model has the same slot spacing on all sides, and the slot insert attachment can be inserted and attachedDocket No. P14510WO00 52 using the first available slot pin plate subassembly or can advance through the center of the open MFD and connect to the slot on the opposite side of the MFD for extra capacity. In some models, the opening in the center of the MFD may also be used to allow cable(s), such as the Load line, jump line, or monkey arm cable, to pass through.

[0313] Fig. 58 is a section view for a first model multifunctional device, showing the slot pins in an open position for all four slots and Fig. 59 is the same view as Fig. 58, but with two slot pins subassemblies closed and two slot pins subassemblies open.

[0314] The external locking pin can be a slot locker or a plunger pin, or other type of bolt or pin that meets functionality requirements. Figs. 60 and 61 show a third model MFD that uses a twist-to-lock plunger pin. The plunger pin can be a retractable spring plunger, twist-to-lock retractable spring plunger, or similar. The slot locker may be attached to the lock pin plate subassembly, where the plunger pin shown in Fig. 61 is attached to a plate nut / threaded connection within the MFD (see e.g., Figs 61 and 64).

[0315] In some embodiments, to hold components in place at the MFD, engagement and / or lock pin plate subassemblies with springs and guide rods can be used. For example, Figs. 60 and 61 show a third MFD model utilizing a compression spring plate. In embodiments that utilize compression springs, an engagement pin plate subassembly may be added to the MFD assembly, and the compression springs will rest between the back side of the slot pin plate and the front side of the engagement pin plate subassembly. The engagement pin plate will rest against or will be attached to the interior sheath wall. The compression springs will be held in position using guide pins that are attached to the engagement pin plate. The compression spring may be placed directly behind the slot pins, or where space is available on the back side of the slot pin plate. If attached directly behind the slot pins, there will be two guide pins: one attached to the alignments spring plate and one attached and centered on the back side of the top and bottom slot pins. The total length of these two guide pins will be no more than what is required to disengage the slot pins fully from the slot. If the compression springs are not attached to the back side of the slot pins, then the alignment pins (1 per spring) will be attached to the alignment spring plate, and project through the slot pin plate, and will project through the first internal fixed structural member(shown asDocket No. P14510WO00 53 angle / bent plate) to hold in position, but no more (See Fig. 61; insert into structural member, shown as angle / bent plate).

[0316] Figs. 61 and 62 show views of the inner parts of a third model MFD for a typical slot section. This section will be repeated for the overall length of the device for all slots on the same face. Perpendicular faces may utilize an internal compression or tension spring system. The models with tension springs may have greater closing force than the compression spring models, but the disadvantage is larger slot pin plates, and larger bearing plates to accommodate for the springs. The center of the MFD is open for this model, shown in Figs. 61 and 62, to allow the slot attachments to advance through and connect to the slot on the opposite side of the MFD for extra capacity, and in some models will also be used to allow cable, such as the load line or jump line cable, to pass through.

[0317] Fig. 63 shows a cut section through a third model MFD slot showing all slot pins in a closed position for compression spring plates. All slot pins are shown in the closed position. The taper point of the slot pin starts at the exterior edge of the fixed structural member for substantially full bearing within the fixed structural member. All slot pins are tapered for ease of entry into the fixed structural member (shown as angle / bent plate. Figure 63 also illustrates how the plunger pin locks the slot closed using the plunger lock pin on the exterior side (side closest to sheath) of the pin plate. This is completed by engaging the plunger pin after the slot pin plate passes by it when engaging the engagement pin (slot in closed position). Fig. 64 is similar to Fig. 63, but with all slot pins in an open position. All engagement pins are shown in the figure as disengaged. When a slot pin is fully disengaged from the slot, a portion of the slot pin remains within the fixed structural member (shown as angle / bent plate) but does not impede / obstruct the slot opening.

[0318] Fig. 64 also illustrates how the slot locker locks the slot open using the plunger lock pin (or locking pin) on the interior side (side furthest from sheath) of the pin plate. When the pin plate subassembly is already engaged and locked in the closed position, it can be unlocked by releasing the slot locker, then releasing the engagement pin (pulling on engagement pin when spring loaded) from the slot, and after the slot pin plate passes by the slot, the plunger pin (or slot locker) can be reengaged to keep slot or end cap in the open position (not engaged). An additional hole(s) is added to the internal fixed structural member(s) for theDocket No. P14510WO00 54 associated locking pin(s) to allow it to project into the IFSM when the pin plate subassembly is in a closed position. This is for the pin plate to rest against the IFSM so the associated slot pins can get full engagement. In some embodiments, the locking pin for locking the slot open may not be included.

[0319] Fig. 65 is a sectional view through a slot showing half of the slot pins in a closed position and half in an open position and used with tension spring plate assemblies. For example, the pins in quadrants 2 and 4 are open, and quadrants 1 and 3 are closed / engaged. The figure shows some of the engagement pins fully engaged (slot in closed position), and others not engaged (slot is open position to accept connections). The figure shows how each slot has an independent pin plate assembly associated with it that either engages (locks in) an inserted slot plate / attachment, or releases said slot plate / attachment. This allows for any slot to be engaged (closed) or disengaged (opened) independently of the other slots.

[0320] Fig. 66 shows an elevation view of the inner parts of the MFD for a non-end slot section for a fourth MFD model utilizing a tension spring loaded system for the slot pin plate subassemblies. As noted, many of the components will be similar between the tension and compression spring models, but the locations and use of some of the components will be varied to accommodate the varying components. The main distinguishing features of the tension spring loaded system, where the tension spring plate subassembly has a different spring plate, and the springs pass through the fixed structural member (shown as angle / bent plate). As shown in Fig. 66, a slot pin plate assembly for tension springs generally includes optional locking pins, a plunger pin, engagement pins, tension springs, and bearing bolts. In some embodiments, perpendicular faces may utilize an internal compression or tension spring loaded system, or no spring system.

[0321] Fig. 67 is a section cut of Fig. 66 and shows a cut section view through a non-end slot section with the slot pin plate subassemblies in a closed position for all slot faces (FA, FB, FC, FD) for a model with tension spring plate system(s). Some of the main differences between the compression and tension spring plate system is the size and shape of the slot pin plate, tensions springs instead of compressions springs, additional hole(s) in the bearing plate(s), and the additional holes in the slot pin plate for the tension system for tension springs to pass through.Docket No. P14510WO00 55

[0322] Figs. 68 and 69 are sectional views of a fourth MFD model that utilizes a tension slot pin plate subassembly. Fig. 68 shows all of the slots in the locked or engaged configuration, while Fig. 69 shows the slot pins in the open configuration. Fig. 70 shows a cut section in the top left quadrant (Q2) of the MFD of Fig. 68 through the bearing plate above a slot connection. Fig. 70 clearly shows the plunger pin / slot locker behind the locking pin, locking the slot closed. Fig. 71 shows a plunger pin / slot locker extended in front of the locking pin, locking the slot open.INSERTS

[0323] In some embodiments, the multifunctional device has one or more inserts, such as an end cap insert and / or a slot insert. The inserts interact with the pin plate subassemblies discussed above.END CAP INSERTS

[0324] In some embodiments, end caps (or end cap insert attachments) may be substantially similar to type 1 through type 5 as described herein. In some aspects, these exemplary end cap subassemblies may be used with the four-sided MFD models of this disclosure. The end cap inserts have at least two, four, or six sides, that may be inserted into an end of an MFD model. In preferred embodiments, the end cap has two sides. Each side may be an insert side or an attachment side. The end cap insert may be one piece or multiple pieces. In preferred embodiments, and discussed further below, the end cap insert comprises at least four parts: two short plates, a long plate, and a top plate. In some embodiments, the end cap insert may only have at least one, two , three, four, or more pieces. The type 1 through type 4 end caps are unique by constraining the top and short plates within the MFD, and allowing the shear tabs to transfer loads through the connected end cap plates and into the MFD sheath when the connection is pulled inward (toward middle of MFD length) in the event the bonding or welding fails. It should be noted that the type 1 through 4 ends caps are individual parts assembled together to create an end cap subassembly, and that there are alternate types of end caps for various MFD models that can be built with multiple pieces or molded into one piece, and some may or may not include additional redundancy. These types of end caps will be discussed further herein.Docket No. P14510WO00 56

[0325] TYPE #1: Figs. 72A-72E shows a type #1 end cap for a four-sided MFD Model.Figs. 72B and Fig 72C show the short and long plate used for the subassembly shown in Fig. 72A. The short plate and long plate are both shown with a keyway (notch) in the side of the plate for MFD models that utilize splice plates and / or end cap reinforcement plates. When the splice plate(s) (or reinforcement plate(s)) is installed, the splice plate bolt(s) / pin(s) are engaged within this keyway (notch). In some embodiments, the keyway for the splice plate(s) (or reinforcement plate(s)) may not be on the end cap(s). The round holes shown in both the short (see e.g, Fig. 72D) and long plates (see e.g., Fig. 72E) are used for the end cap slot pins for locking in the end cap subassembly (End Cap Insert attachment) within the MFD.

[0326] The Type #1 (Fig. 72A) and Type #2 (Fig. 73A) subassemblies are similar, but the type #1 incorporates a padeye (lifting lug / shackle hole) in the long plate that projects out of the end cap (Side #2=Attachment side). The padeye (lifting lug / shackle hole) can be utilized for hoisting / lifting the MFD, and / or for attaching rigging to. The shape and size of the short and long plate that fits into the MFD end will generally match the internal opening / shape of the internal fixed structural members, and when used as a bearing plate(s) will extend to the top of the closest slot on the end of the MFD (end #1 or end #2).

[0327] In some embodiments, the parts shown are bonded or welded to each other after assembly. Furthermore, the end cap inserts incorporate keyways and shear tabs for additional redundancy to any of the bonds (example: welds) connecting the parts together. For example, Figs. 72B - 72E show the subassembly and the parts needed for the end cap shown in Fig. 72A. The shear tabs for the short plate shown on the right side of Fig. 72D fit into the shear opening shown in middle of the long plate in Fig. 72E. Once the long plate and short plate is connected, the connected plates fit thru the top plate shown in Figs. 72B-72C until the shear tabs on the top exterior of the short (top left of Fig. 72D) and long plates (top left and top right of Fig. 72E) rest against the top plate. Once these pieces are connected like shown in Fig. 72B and 72C, they are bonded or welded together. When the end cap (end cap insert attachment) is installed into a compatible MFD model, the shear tabs shown on the left side of the short plate (called out as ledge for sheath keyway in Fig. 72D) and the shear tabs on the left and right side of the long plate (called out as ledge for sheath keyway in Fig. 72E) will fit into the opening of the sheath. The shape and size of the short and long plate that fits intoDocket No. P14510WO00 57 the MFD end will generally match the internal opening / shape of the internal fixed structural members, and when used as a bearing plate(s) will extend to the top of the closest slot on the end of the MFD (end #1 or end #2).

[0328] TYPE#2: Figs. 73A-73E shows a type #2 end cap for a four-sided MFD Model.The type #2 end cap is for connecting to the end(s) of the MFD, and it is primarily used for the very end of a MFD. The Type #2 subassembly shown for this four-sided MFD model is made up of 4 primary pieces, two short plates shown in Fig. 73D, one long plate shown in Fig. 73E, and one top plate shown in Figs. 74 and 73B-73C.

[0329] TYPE#3: Figs. 75A-75E shows a type #3 end cap for a four-sided MFD Model.The MFD is designed for interchangeable end caps, so if a MFD needs to be used in a near vertical, or vertical configuration, then the type #3 end cap may be attached to the bottom of the MFD to support the MFD in lieu of using the slot plate insert attachment (s) installed on the side(s) of the MFD. The type #3 end cap can be supported by either using the holes below the top plate, or by placing the pin shown directly into a mount / structure with a hole that matches the profile of the pin but with a slightly larger diameter to allow the pin to fit into. The type #3 end cap is generally used for the very bottom end of a MFD. The parts used for this Type #3 subassembly are shown in FIG. 75B-75E. Type #3 end cap subassemblies may or may not have cheek plates and may or may not have bearing plate and pin on side #2 (Side with check plates).

[0330] TYPE#4: Figs. 76A-76E shows a type #4 end cap for a four-sided MFD Model. In some embodiments, two MFD models may be connected from end to end using insert attachments, such as splice plate(s), and the 2 MFDs are connected together using end cap type #4 shown on Fig. 76A . End Cap type #4 is a two-sided end cap and is used for connecting one MFD to another MFD. The profile above, or below the top plate is shown as the same in the figure, but it should be noted that the profile on one side will match the profile needed for the MFD being connected on this side, and the profile on the opposite side will match the profile needed for the MFD being connected on said side (Similar to Type 1 through type 3 end cap subassemblies). For example, a MFD 4-sided model may be connected to a MFD 2-sided model if both profiles of the end cap type #4 matched with theDocket No. P14510WO00 58MFDs. The type #4 end cap subassembly may also have notches in the top plate like those shown in Fig. 76A for the connection of any reinforcement / splice connection.

[0331] TYPE#5: Figs. 77A-77C shows a type #5 end cap for a four-sided MFD Model.Adjusting the outer widths of the top plate shown in Fig. 74 and adding holes into the plate, and then adding an additional independent top plate with a similar profile (similar cut out, shape, size, holes) on side #2 (plug side) of the end cap results in a type #5 end cap. The type #5 end cap allows the MFD to be mounted to a concrete slab or structure using the end cap(s). The type #5 end cap is an interchangeable end cap insert attachment for connecting to the end(s) of the MFD, and it is primarily used for the very end of a MFD to connect, or be bolted to, a concrete slab or structure using the end cap(s). The Type #5 subassembly shown for this four-sided MFD model is made up of 5 primary pieces, two short plates, one long plate, and two top plates with mounting holes as shown in Figs. 77A-77C. The type #5 subassembly parts are shown bonded to each other in Fig. 77B, and Fig. 77A shows the independent plate (Fig. 77C) added to this subassembly to create the Type #5 end cap.

[0332] It should be noted that the quantity, size and location of holes in the subassembly parts, and the material, shape, and quantity of plates (Example: short plate and long plate) used for the subassemblies may change depending on the MFD Model, and generally the profile / shape of the plates that extend below (toward interior side of MFD) the top plate will match the profile within the MFD internal fixed structural member(s) for the associated MFD model. For example, a two-sided MFD model may have an end cap subassembly made up of only two primary members, the top plate (notched out just for the long plate), and the long plate (which will rest within the MFD internal fixed structural members). It should be noted that the end caps shown in the figures are all shown as subassemblies but may also be molded as one piece.

[0333] Fig. 79 shows multiple MFDs of the same MFD models connected perpendicular to each other using the end caps of Fig. 78, where side #2 goes into the end cap (end cap insert), and side #1 goes into the slot (slot insert) on the side of a MFD for each of the shown connections. The MFDs are connected using an insert attachment where the end cap plates that go into MFD#1 (end Cap Side #1) match the end cap opening profile of MFD #1, and slot plate insert attachment that go into MFD#2 (End Cap Side #2) match the slot profile of end ofDocket No. P14510WO00 59MFD #2. The hole diameter, quantity, and locations for the side cap slot plate insert attachment (s) will match those of the associated slot plate insert attachments or end cap insert attachments for the associated MFD Model that is being connected to. The insert portion that goes into the slot may project into the MFD to allow it to connect to the first pin plate subassembly, or when the MFD is configured with the same slot sizes at the same elevation on opposite sides that the insert may project into or through the MFD to allow it to connect to the opposite side of the MFD to the associated pin plate subassembly (See e.g., Side #1 of Fig.78) and / or connect to both pin plate subassemblies for additional capacity.SLOT INSERT ATTACHMENTS

[0334] Figures and descriptions herein describe some of the slot insert attachments of a multifunctional device for use in construction. Figs. 80A-80B show a slot insert attachment for a MFD with side #1 configured for a slot attachment, and side #2 configured for an external attachment. Side #1 only has one column of holes so can only be attached with one slot pin plate subassembly. It should be noted that all slot insert attachments that have an external attachment may have cheek plates on each side of the plate at the attachment location(s).

[0335] Fig. 81A shows a slot insert attachment similar to Figs. 80A-80B but has three different holes on the exterior allowing for multiple attachment points, and with different size holes to accommodate different sizes of shackles / connections into the plate. Fig. 81B shows a slot insert attachment similarto Fig.81A, but with 2 vertical columns of holes on side #l (slot insert side) to allow the slot plate insert attachment to be connected using the first, second, or first and second slot pin plate subassemblies for a MFD that has slots that are the same shape, size, on opposite sides, and at the same elevation. Fig. 81C shows a slot insert attachment similar to Fig.85B, but with side #1 and side #2 both being attachment ends. The slot insert of Fig. 85C may be used where similar sized slots are located at the same elevation and exist on opposite sides of the MFD, such as the first MFD model.

[0336] Figs. 82A-82B display rail attachments. The rail attachment comprises a slot plate insert attachment with a piece of angle connected to it, via welding or the like. In embodiments, the insert attachment is designed to be inserted into the MFD standard slot(s) and allows for the user to place one, or two overlapping structural member(s) (e.g., 2X4(s)) into the angle to be used as a rail (footrail, midrail, handrail). Once inserted into the MFD, theDocket No. P14510WO00 60 structural member(s) can be placed into and connected to the rail attachment to keep the rail secure. The angled portion could also be attached at or near the upper end of the slot attachment.

[0337] Fig. 84 shows two of the same MFD models connected perpendicular to each other using the insert attachment of Fig. 83. Fig. 83 shows an insert attachment for connecting the side of a MFD to the side of another MFD. Side #1 is a slot insert connection, and Side #2 is a slot insert connection . This two-sided attachment is designed to connect the side of one MFD to the side of another MFD, as shown in Fig. 84 but, each side could have two vertical columns of holes on each side to allow it to connect to one or two pin plate subassembly(s) for each MFD connection. The 2 MFDs are connected, and the slot insert that goes into MFD#1 matches the slot profile of MFD #1, and slot insert that projects into MFD#2 match the slot profile of MFD #2. The hole diameter, quantity, and locations for the insert attachment(s) will match those of the standard slot plate insert attachments for the associated MFD Model and associated slot that is being connected to. The insert portion that goes into the slot may project into the MFD to allow it to connect to the first pin plate subassembly, or when the MFD is configured with the same slot sizes at the same elevation on opposite sides that the insert may project into or through the MFD to allow it to connect to the opposite side of the MFD to the associated pin plate subassembly and / or connect to both pin plate subassemblies for additional capacity.

[0338] Fig. 85 shows an insert attachment for connecting the side of a MFD to the side of another MFD. Side #1 is a slot insert connection, and Side #2 is a slot insert connection . This insert attachment is designed to connect the side of one MFD to the side of another MFD and incorporates a hinge between Side #1 and Side #2 allowing rotation. The insert shown on the left side (side #1) of the figure for this attachment model shows one column of holes allowing this side of the insert to be connected to only one pin plate subassembly, where the insert shown on the right (side #2) has 2 columns of holes allowing it to be connected to one, or two pin plate subassemblies.

[0339] Fig. 86 shows a plug plate slot insert attachment. A plug plate attachment can be used with an MFD and comprises a slot plate with a tab that extends out, and projects above and below the slot opening. In embodiments, the slot plate is intended to be used to connect theDocket No. P14510WO00 61 interior of the MFD to the exterior of the sheath of the MFD, and in many cases may be used to increase capacity of the MFD as needed. In addition, some plug plates will be designed to hold in some MFD Splice and / or end cap reinforcement plates.

[0340] Figs. 87A-87D show variations of MFD insert attachments, where side #2 of an attachment can be angled (horizontally and / or vertically) and / or rotated to meet alignment needs from one MFD to another MFD.

[0341] Figs. 88A-88B show an insert attachment with slot inserts on side #1 and a plug plate on side #2. This insert attachment is a splice plate attachment for a MFD. The splice plug plate attachment is designed to connect the MFD to MFD to maximize the available capacity of the assembled MFD, when installed in a linear configuration. Similarly, Figs. 89A-89B show another version of a splice plug plate attachment, which is designed to connect the MFD to MFD to maximize the available capacity of the assembled MFD, when installed in a linear configuration. It should be noted that there will be various types of splice plate attachments available for connecting one MFD to another MFD, when needed.

[0342] Figs. 90 and 91 show variations of an insert attachment used to bear against a structural member when using the MFD. Fig. 90 shows side #2 with half-pipe members, and Fig. 91 shows side #2 with an angle member attached. Both insert attachments are similar in functionality by providing a bearing location to transfer load from a structure directly into the slot insert(s) and keeping the MFD face off the structure.ATTACHMENTS

[0343] Further optional insert attachments of a multifunctional device (MFD) for use in construction are described herein. The various figures and description below describe multiple MFD insert attachments for slots and / or end caps for a MFD that may additionally contain an attachment side, such as monkey arms, or interact with both slots and end caps, such as splice plates. The end caps shown are in addition to the type #1 through type #5 endcaps already discussed and are only a small sample set of the almost unlimited number of connections that will be available for connecting to the MFD. The hole quantity, size(s), and placement for connecting the end cap(s) and slot insert(s) to the MFD will match the associated (end cap or slot) pin plate subassemblies for functionality with the MFD. The end cap connections may be configured to allow the attachment of MFD reinforcement membersDocket No. P14510WO00 62(splice plate(s) and / or end cap reinforcement plate(s)). Many MFD connections may be molded out of one piece or made of multiple pieces to create a subassembly. The connection of the end cap to MFD and slot plate insert attachment(s) to MFD is similar to the type #1 through type #5 end caps and the slot plate insert attachments already discussed above.

[0344] Fig. 92 shows a splice plate used for a first model MFD. Figs. 93 and 94 show multiple MFD's connected together using this splice plate(s). Figs. 94 and 94 both show two of the same MFD models connected from end to end using splice plate(s). The splice plate(s) may be required to connect the MFD from end to end to increase the length of the MFD, and to provide additional capacity to the MFD. In embodiments, the splice plate(s) is attached to the exterior wall of the sheath using either bolts or pins. The splice plate shown in Fig. 92 has four slot openings to allow slot plate insert attachments or plug plates to insert, has threaded holes in it for a partially threaded pin to thread into (only threaded for splice plate portion), has a hole in the very center for the end cap, and has holes in it for the engagement pin(s) and slot locker(s) (or plunger pin(s)) to project through. In embodiments, the splice plate of Fig. 92 only has slot openings (no slot plates bonded to it), plug inserts or slot inserts with tabs are required to be inserted in the slots to lock this splice plate to the face(s) of the MFD. The splice plate may be manufactured as single plate, a subassembly, or molded as one piece. In some embodiments, the splice plate is a subassembly that allows the wearable components, such as the partially threaded pins, to be changed out to increase the life span of the splice plate. The splice plate may be installed on one, multiple, or all faces of the MFD for the associated installation elevation, and dependent on application. The splice plate may be fabricated with or without one, multiple, or all slot plate insert attachments attached / bonded to each other. The splice plate may be sized and shaped such that is attached to one, or multiple slots on the same MFD, and the size, quantity, and location of splice plate pins / bolts as well as the reinforcement holes that go through the splice plate and into the sheath may vary depending on the MFD Model.

[0345] In embodiments, the splice plate is installed using a partially threaded pin. The installation of this splice plate is completed in one of two ways, either the splice plate partially threaded pins are already installed in the splice plate and then the splice plate with pins are pressed into place until the splice plate rest against the sheath wall, or the just the splice plateDocket No. P14510WO00 63 is placed against the sheath wall with all holes aligned with the holes of the sheath, and then the partially threaded pins can be threaded into the splice plate, or a combination thereof. Once the splice plate is installed, a slot plug plate, or slot insert with similar tabs, may be inserted into the slot openings, and then the engagement pin(s) and slot locker / plunger pin(s) can be installed and engaged to lock the splice plate in place. For removal of the splice plate(s), the slot locker / plunger pin(s) associated with the splice plate(s) are removed, and the engagement pin(s) associated with the splice plate(s) are removed, then the slot plate insert attachment(s) associated with the splice plate(s) are removed. Once these items are removed, the splice plate can be removed from the face of the MFD.

[0346] If the splice plate cannot be removed without the aid of using other tools, then either some or all of the partially threaded pins can be removed and then splice plate removed, or one or more of the partially threaded pins can be removed and a longer partially threaded pin can be threaded into the splice plate until the pin pushes against the MFD internal bearing plates (keyway for splice plate) in which case the partially threaded pin is threaded into the splice plate further pushing the splice plate away and disconnecting it from the sheath wall. Installing and removing the end cap reinforcement plate is similar to installing and removing the splice plate(s). It should be noted that the splice bolt(s) / pin(s) for a splice plate(s) can be partially threaded, and / or bonded directly to the splice plate.

[0347] Figs. 95A-95D show a universal rotating adjusting attachment to attach to an MFD insert attachment. The attachment is used to mount the MFD to structural members on a structure, can rotate 360-degrees in one direction, and may be able to rotate 180-degrees in the other direction using a hinge type of system which can be locked as required, and allows for adjustability in length to meet length requirements. The slot insert attachment inserts into the MFD slots and locks to the MFD using the slot pin plate subassembly(s). It should be noted that this attachment is shown as a subassembly and wearable components can be replaced as needed, and that some of the parts that do not rotate may also be molded out of one piece. The size and shape of this attachment may change to meet functionality requirements.

[0348] For towers, this may be used to attach directly to the tower legs and rotated as needed for the application. This may also be used as a bracing device for tower members during modification work (examples include temporary bracing for legs, horizontals (girts), diagonals,Docket No. P14510WO00 64 etc.). When towers have members that require replacement, the clamp attachments will be used to attach the MFD to the tower, to brace that section so that a member at that location may be replaced with a stronger member. Without such a bracing device, the tower may become unstable during repairs leading to structural failures. This would not be limited to just towers; it works for other structures that require modifications. Note that there is not shown a lockable hinge that can be added between the channel and rotating pins. This will allow the MFD to be rotated from connection.

[0349] Figs. 96-109B show various attachments referred to as "monkey arm" attachments. These figures and description below refer to monkey arms, which are external attachments of a multifunctional device (MFD) and are shown in the figures as attached to an insert attachment where side #1 is a slot insert and side #2 is an attachment end for connecting to the monkey arm for use in construction.

[0350] Fig. 96 shows an example of a monkey arm model. The "MONKEY ARM" attachment is composed of back-to-back angles, back-to-back channels, or other types of back-to-back structural members that attach directly to the MFD Slot insert attachments (on side #2). The "Monkey Arm" attaches next to, and parallel to, the MFD for transporting, and hoisting, and can be installed on one, multiple, or all sides of the MFD. Figs. 97A and 97B show similar monkey arm models in a transport configuration. Once hoisted and attached to the structure, the "Monkey Arm" is unpinned (or unbolted) from end #2, and then the slot is disengaged at the slot attached to the "Monkey Arm" Hinge (where the two double members meet), then rotated to the desired configuration and reattached back to the MFD using the slot insert attachment (see, e.g., Figs. 97C and 98 where the monkey arm is in a working configuration on just one side of a MFD). The monkey arm bracing members may be attached back to the MFD either below, or above the monkey arm boom. When the bracing is below the boom, the load line passes through / between Boom bracing structural members. Connection to the MFD can be directly to the MFD Slot insert attachment attached at the hinge, or to another pad eye attached to the boom, or attached directly to the lifting lug directly below the Monkey Arm roller. Additional holes will be added to the monkey arm to attach to other slots on the MFD when folded down, or for more attachment options, such as adding sheavesDocket No. P14510WO00 65 between the back-to-back members. When in the vertical positions, the back-to-back structural members will also act as additional protection to the MFD.

[0351] Any model of a MFD may have monkey arms associated with it. Generally, when the "MONKEY ARM" is used on multiple MFDs, the slot spacing and slot sizes for the connected MFD's are spaced equally on the same face of the MFD that the "MONKEY ARM" will be connected. For example, a first model MFD that has all the same slot sizes, equal spacing along the entire length on each and all sides of the MFD, which would allow for equal spacing when the MFDs are connected together regardless of the ends or faces connected, allowing the "MONKEY ARM" to be connected on any face and to the same, or multiple MFDs.

[0352] Figs. 99A-100B show an MFD having two monkey arm attachments. The attachments are mounted on opposite sides of the MFD. Figs. 99A-99B show the transport mode for the multiple monkey arms. Figs. 100A and 100B show the monkey arms in the extended version, or working configuration. Note that the figures show the monkey arms to be substantially symmetrical, but this is not required. It is contemplated that the monkey arms could have different lengths on the opposite sides of the MFD, or they could be mounted at different locations along the length of the MFD. The monkey arm boom length and bracing lengths may vary depending on differing monkey arm models.

[0353] For example, Figs. 101A-101D show the attachment of another monkey arm model with different boom and bracing lengths that are attached at different locations along the length of the MFD, such that the lower end is attached at the lower end of the MFD.

[0354] Another example is shown in Figs. 102A-102B. In such a configuration, there are two MFDs that are attached to one another in a longitudinal manner. A monkey arm attachment is connected to both of the MFDs. This would allow the monkey arm to be placed at a higher location. This also shows that the position of an attachment can vary according to use in the field. The figure represents how the MFD's can be connected linearly, and the Monkey Arm can be attached to two different MFD's if needed. There will be several different Monkey Arms lengths with different available offsets available depending on the user's needs.

[0355] Another iteration of a Monkey Arm is shown in Fig. 103 where sheaves are added between the back-to-back structural members to guide / direct rope or cable to desiredDocket No. P14510WO00 66 locations as needed for the hoisting configuration needed by the used. Some monkey arm models will allow for these sheaves to be added as needed to meet the user's needs.

[0356] Fig. 104 shows an insert attachment with a sheave attached. Side #1 is a slot insert that fits into the side of a MFD, and Side #2 in configured with a sheave and exterior plates. Side #1 for this attachment model has two columns of holes allowing it to be connected to one, or two pin plate subassemblies. Side #2 incorporates a sheave for redirecting rope or cable. This type of connection could be used for redirecting rope or cable.

[0357] Fig. 105A shows an insert attachment with a sheave attached. Side #1 is an end cap insert that fits into the end of a MFD, and Side #2 in configured with a sheave and exterior plates (AKA: Rooster head). A rotating bearing is also shown between side #1 and Side #2 to allow the sheave (Rooster head) to rotate on top of the MFD. The center of the rooster head and center of the MFD is open to allow rope or cable to pass through. This sheave is also used to redirect rope or cable as needed. Fig. 105B also shows an insert attachment similar to the one shown in Fig. 105A, but without the rotating bearing meaning this connection is stationary (can't rotate in relation to attached MFD) on the top of the MFD.

[0358] Fig. 106A shows a transport wheel attachment for an MFD. This attachment incorporates wheels, and uses a slot plate that slots into the MFD. The wheels can be added to transport the MFD as needed. Fig. 106A shows just the attachment plus wheels, and Figs 106B-106C show the wheel attachment installed on a MFD. This allows the MFD to be moved, or a combination with attachments to be moved more easily.

[0359] Fig. 107 shows an insert attachment, where side #1 is a slot insert, and side #2 is considered an external attachment. The attachment on side #2 is shown as a rectangular support but could be any material or shape as needed to meet functionality requirements. This attachment is used to allow the MFD to be mounted within an opening of a structure.

[0360] Fig. 108 shows an insert attachment, where side #1 has two slot plates (Inserts), and side #2 is considered an external attachment. This type of attachment may also be referenced as a bumper pad. The bumper pad attachment connects two slot plates (inserts) into two slot openings in the side of a MFD. On Side #2 (attachment side), two back-to-back structural members (shown as angles) are positioned on each side of the plate. In the middle along the length of the back-to-back structural members is an additional plate matching the slot plateDocket No. P14510WO00 67 thickness and is sandwiched / bonded within the two structural members that will generally rest against the MFD exterior wall of the sheath when installed. The slot plates on side #2 are connected to the back-to-back structural members using a pin. This type of attachment may be used between the MFD and a structural member to allow the MFD to rest against said structural member when the MFD slot spacing does not match up with said structural Member.

[0361] Fig. 109B shows an end cap insert attachment having an adjustable shoring jack for adjusting the elevation of a MFD, and allows the MFD to be used as shoring post like shown in Fig. 109A. The end cap shown on Fig. 109B is similar to the type #2 end cap insert attachment, but has a threaded hole in the middle to accept the screw from the shoring jack portion shown in Fig. 109A. Figure 109C is a side view of two multifunctional devices with the insert attachment of Fig. 109B.

[0362] Note that the following are MFD attachments that could be used with a MFD as disclosed. However, note that these are not to be limiting in nature, and that they are included as possibilities and / or alternatives for use. Additional end plate connections to connect multiple poles end to end, which can allow for larger loads to be hoisted and greater offset distance to help clear other mounts, etc. A rotating bearing assembly attached to the end plate. A pad eye plate will be attached to the end plate, where the lifting block will connect to. This component can allow the user to rotate the load and be able to hoist the loads in any direction required. A base plate attachment that would allow a load hoist to be attached directly to the MFD itself, thereby reducing the forces through the system allowing user to lift more weight. An attachment to add wheels to for rolling the MFD around.METHODS OF USE

[0363] Moving now to Fig. 110A, the figure shows how a MFD could be attached to a parapet wall in a vertical configuration. As shown in the figure, a claim can attach to screws / coilrods and wrap around the MFD at the parapet. The tightening of the screws or other fasteners will aid in holding the MFD in place. Another configuration is shown in Fig. HOB, where the MFD is connected to the parapet in a horizontal manner.
