Description

Technical Field

[0001] The present disclosure relates to an access system, and more particularly to a system designed to access the lower surface and side portions of a large stationary structure surface. More particularly, the present disclosure relates to a mono rail system, which is used in combination with a scaffolding structure, and additional scaffolding structures are suspended from the mono rail system and can be moved vertically and parallel to the monorail track relative to the structure to be accessed

Background Art

[0002] In the construction, repair, and restoration industries, there are often cases where it is necessary to access the side surfaces and lower surfaces of structures during work, and accessing these surfaces from below (e.g., erecting a standard scaffold) is impractical or impossible There are many such cases. For example, bridges, and especially arch bridges, span canyons or rivers, for example It is often difficult to access the lower surfaces of these bridges because scaffolds cannot be erected upward from the ground and also because the presence of the arch (which creates a surface of constantly changing height) makes access even more difficult. The same is true for certain side surfaces Suspended scaffolds are known and can be used in certain cases to access such side and lower surfaces. Suspended scaffolds have their own problems. For example, suspending a scaffold at a location where an operator can access the required surface is practical

[0003] not always possible and the scaffold may need to be adjusted multiple times to reach different areas of the surface ​​​​It may not be or may not be possible. Also, the length of the surface may also be a limiting factor. If the structure being accessed spans a very long length, the amount of suspended scaffolding may require multiple assembly / disassembly operations to complete the entire job. Further more, especially in the case of an arch-shaped structure, the suspended scaffolding may need to have multiple levels which results in additional complexity and time in assembly / disassembly.

[0047] Scaffold frame member FIG. 13 shows a top perspective view of the connection between a single interconnect structure 10 and a single scaffold frame member 30, while FIGS. 14A and 14B show an exploded enlarged view and a normal perspective enlarged view, respectively, of typical connection details between the interconnect structure 10 and the scaffold frame member 30. When used in a suspended articulated scaffold system, the scaffold frame member 30 is referred to as a joist 30.

When used in a suspended articulated scaffold system, the scaffold frame member 30 is referred to as a joist 30. When used in a suspended articulated scaffold system, the scaffold frame member 30 is referred to as a joist 30.

[0048] The joist 30 includes an upper element 32 and a bottom element 33. A plurality of diagonal support members 38 are interspersed between the element 32 and the element 33. Each of the elements 32, 33 is made from two L-shaped pieces of angle iron 39A, 39B. The elements 32, 33 are typically such that the upper element 32 The joist 30 includes an upper element 32 and a bottom element 33. A plurality of diagonal support members 38 are interspersed between the element 32 and the element 33. Each of the elements 32, 33 is made from two L-shaped pieces of angle iron 39A, 39B. The elements 32, 33 are typically such that the upper element 32 The joist 30 includes an upper element 32 and a bottom element 33. A plurality of diagonal support members 38 are interspersed between the element 32 and the element 33. Each of the elements 32, 33 is made from two L-shaped pieces of angle iron 39A, 39B. The elements 32, 33 are typically such that the upper element 32 The joist 30 includes an upper element 32 and a bottom element 33. A plurality of diagonal support members 38 are interspersed between the element 32 and the element 33. Each of the elements 32, 33 is made from two L-shaped pieces of angle iron 39A, 39B. The elements 32, 33 are typically such that the upper element 32 Except for including connector hole portions 54A and 54B at the center (for example, refer to FIGS. 16A and 1 6B), the construction can be the same. The joist 30 includes a first end 31 A and a second end 31B. At either end 31A or 31B of both the upper element 32 and the bottom element 33 , an upper connection flange 35 and a lower connection flange 36 extend. A connection hole portion 37 passes through both the upper connection flange 35 and the lower connection flange 36. Therefore, there are four upper connection flanges 35A, 35B, 35C , 35D; and four lower connection flanges 36A, 36B, 36C, 36D. Thus , at the first end 31A, the upper connection flange 35A and the lower connection flange 36A (with a connection hole portion 37A passing through it) extend from the upper element 32 . Similarly, at the second end 31B of the upper element 32, the upper connection flange 35B and the lower connection flange 36B (with a connection hole portion 37B passing through it) extend. Subsequently , at the first end 31A of the lower element 33, the upper connection flange 35D and the lower connection flange 36D extend. The connection hole portion 37D passes through these connection flanges 35 D, 36D. At the second end 31B of the joist 30, the upper connection flange 35C and the lower connection flange 36C (with a connection hole portion 37C passing through them) extend from the lower element 33.

[0049] Additional locking hole portions 360A, 360B, 360C, 360D, which are similarly positioned above the connection flanges 35A, 35B, 35C, 35D, are inside the respective connector hole portions 37A, 37B, 37C, 37D.

[0050] As more clearly shown in FIGS. 14A and 14B, pin 40 can be installed through connection hole portion 37 and two corresponding upper openings 13 and bottom openings 14 of the interconnect structure 10 . Thus, the joist 30 can be connected to the interconnect structure 10 in virtually an infinite number of ways (and angles ). For example, pin 40 can be installed through upper connection flange 3 5A; through opening 13A; through lower connection flange 36A (all of the first end 31A of upper element 32); through upper connection flange 35D; through opening 14A ; and then through lower connection flange 36D. In this scenario, pin 40 further passes through connection hole portions 37A and 37D. Pin 40 includes two roll pins 42 at its upper end. The lower sides of the two roll pins 42 act as stops, thereby preventing pin 40 from slipping completely through the joist 30 and the interconnect structure 10 . The upper roll pin 42 acts as a finger hold, enabling easy gripping of pin 40 and removal from the joist 30 and the interconnect structure 10 .

[0051] The design of these various parts allows for free rotation of both the joist 30 and the interconnect structure 10 even while they are connected together . Rotation arrow R indicates the rotation of the joist 30, while on the one hand, rotation arrow R 1 indicates the rotation of the interconnect structure 10. These rotational capabilities of the joist 30 and the interconnect structure 10 partially provide the articulation capabilities of the present invention . On the other hand, rotation arrow R 2 indicates the rotation of the interconnect structure 10. These rotational capabilities of the joist 30 and the interconnect structure 10 partially provide the articulation capabilities of the present invention . .​​​

[0052] The joist 30 and the interconnecting structure 10 are allowed to rotate freely, but the modular section or unit of the pace frame support system is assembled and ready for use, such free rotation is restricted. In certain embodiments, the free rotation is restricted by at least one of the following: i) an additional (second) pin positioned adjacent to the perimeter of at least one interconnecting structure; and ii) at least a portion of the work platform when the platform is positioned in an extended position relative to the interconnecting structure and the joist.

[0053] In the particular embodiment shown, a second optional locking pin 40B can be added at the end of the joist 30 through locking holes 360A, 360C, 360C, 360D and, if so desired, locks the joist 30 and prevents articulation. The locking pin 40B abuts against a groove 24 on the interconnecting structure 10. The groove is located on both the upper element 11 and the bottom element 12. Similarly, the locking pin 40B can include, like the pin 40, two additional roll pins 42.

[0054] The joist 30 shown in the figures is made of elements of a particular shape, but it should be apparent to those skilled in the art that other embodiments exist that provide aspects of the present invention. The joist can be any elongated structural member adapted to support or carry a load (e.g., a bar joist, a truss, or a formed steel (i.e., an I-beam, a C such as a joist). For example, the joist 30 in the figure is generally a version ist, or an open web beam or joist that may be referred to. Also, the joist 30 can be made of formed steel (e.g., a wide flange element, a narrow flange member, etc.) or other suitable shapes and materials.

[0055] The assembly of the interconnecting structure 10 and the joist 30 to form a section or unit 115 of the modular space frame support system 100 is discussed in more detail below.

[0056] FIG. 15 shows a single section or unit 115 of a modular space frame support system 100 fabricated using the interconnecting structure 10 and the joist 30 . Note that the four interconnecting structures 10A, 10B, 10C, 10D are interconnected with four joists 3 0A, 30B, 30C, 30D. FIG. 15 shows a single frame unit 115 that is square in a plan view. It should be apparent to those skilled in the art that other shapes and configurations can also be fabricated. For example, by varying the length of the joist 3 0, other shapes can be fabricated. For example, a rectangular frame unit 115 can be constructed. Also, by attaching the joist 30 to various openings 13, 14 of the interconnecting structure 10 , various angles at which the joist 30 interconnects with the interconnecting structure 1 0 can be achieved. For example, a triangular frame unit 115 (not shown) can be constructed in a plan view. Thus, the length of the joist 30 ​​​​​By changing (see, e.g., FIGS. 27A-27D), and / or by changing the angle by which the joist 30 extends from the interconnect structure 10, virtually frame units 115 of any shape and size, and as a result, the resulting modular space frame support system 100 and work platform system 20 0 can be constructed. Further, frame sections of different shapes, sizes, and configurations or units 115 can be joined and abutted to each other, and the modular space frame support system design (and, work platform system design) is virtually completely customizable. This adaptability of the modular space frame support system 100 provides a convenient way to gain access to virtually any shaped work area required in construction. FIGS. 16A, 16B, and 16C show various views and enlarged views of the interconnection between the intermediate support deck joist 52 and the joist 30. The intermediate support deck joist 52 provides additional

[0057] support to support the platform 50 (see, e.g., FIG. 17) and can span between two joists 30. Pins 53 are at each end of the intermediate support deck joist 52, and the pins 53 communicate with corresponding holes 54 in the upper side portions of the joists 30. For example, FIG. 16B shows an exploded view of the interconnection, and the pin 53 will enter into the hole 54A.

The deck retainer plate 60 is one way to fix the work platform 50 to the modular space frame support system 100.

[0060] As shown in FIGS. 20 and 21, there are virtually no limitations regarding the size and shape of the modular space frame support system 100 and the work platform system 200 that can be fabricated in accordance with the present disclosure. FIGS. 20 and 21 show a single-level modular space frame support system 100 with the work platforms 50 in the appropriate positions for fabricating the work platform system 200. Shows a top perspective view and a bottom perspective view of one large rectangular embodiment, respectively.

[0061] As described above, one drawback of many existing work platforms is that they cannot be installed on-site, and also that while a portion of the work platform is already installed in place, they cannot be repositioned, expanded, or removed. This disclosure overcomes this drawback. That is, the modular space frame support system and the resulting work platform system enable an operator (or operators) to add additional sections of the modular space frame support system 100 (and ultimately, the work platform system 200) on top of (while this operator is physically on top of an existing installed portion or unit of the modular space frame support system and / or the work platform system). That is, the operator can expand, reposition, or remove a portion of the work platform system 200 and / or the modular space frame support system 100 by only requiring hand tools. No mechanical tools, hoists, cranes, or other equipment are required to add to (and then remove from) or reposition the modular space frame support system 100.

[0062] Figures 22 through 26 show using the interconnect structure 10 and the joist 30 at a predetermined location The progressive articulation of only one section or unit 115 of the modular space frame support system 100 when disposed therein is shown. This can be readily achieved by one (or two) operator(s) by simply sequentially installing additional joists 30D from the existing interconnect structure 10A. Subsequently, the "new" interconnect structure 10D is connected to the first joist 30D. A second additional joist 30E is connected to the interconnect structure 30D. Furthermore, another interconnect structure 10E and joist 30F are connected such that the final joist 30F returns and is connected to the existing interconnect structure 10B. In this way, an operator can install a new section or unit of the modular space frame support system from an existing section of the modular space frame support system (e.g., composed of, among others, hubs 10A, 10B, 10C and joists 30A, 30B). The operator can install (or relocate) a new section or unit of the modular space frame support system 100 while remaining on an existing section of the work platform 50. That is, no additional lifting equipment (machinery) is required to install, relocate, or remove an additional unit or section of the modular space frame support system when fabricated using the interconnect structure 10 and joists 30. For example, the modular space frame support system may be composed of, among others, hubs 10A, 10B, 10C and joists 30A, 30B. The modular space frame support system may be composed of, among others, hubs 10A, 10B, 10C and joists 30A, 30B. and joists 30A, 30B). The operator can install (or relocate) a new section or unit of the modular space frame support system 100 while remaining on an existing section of the work platform 50. For example, the modular space frame support system may be composed of, among others, hubs 10A, 10B, 10C and joists 30A, 30B. The modular space frame support system may be composed of, among others, hubs 10A, 10B, 10C and joists 30A, 30B.

The modular space frame support system may be composed of, among others, hubs 10A, 10B, 10C and joists 30A, 30B.

[0063] Furthermore, the installer does not need to extend beyond the existing installed frame unit 115, or they only need to extend slightly beyond the installed frame unit 115. For example, as shown in FIG. 22, when the installer relocates (or installs) the next section of the modular space frame support system 100, they can be on top of the existing work platforms 50A, 50B, 50C, 50D. As clearly shown in FIGS. 23 through 25 via the motion arrow “M”, the new joists 30D, 30E, 30F and the combined rotation of the new interconnect structures 10D, 10E allow the new section of the modular space frame support system 100 or unit 115 to move and rotate to its ultimately required location. That is, the units of the modular space frame support system 100 articulate to the appropriate location. Further, while the installer remains on top of the existing frame unit and / or work platform system, the articulation can be started and

[0064] stopped (and even reversed) by the installer. Although not shown, additional assistive devices (e.g., motors, hand tools, mechanical tools, hydraulic devices, etc.) can be used to assist with the articulation. FIG. 26 shows the modular space frame articulated to the appropriate location prior to the installation of the support platform 50 and any other pieces, as discussed herein. That is, the units of the modular space frame support system 100 articulate to the appropriate location. Further, while the installer remains on top of the existing frame unit and / or work platform system, the articulation can be started and stopped (and even reversed) by the installer. Although not shown, additional assistive devices (e.g., motors, hand tools, mechanical tools, hydraulic devices, etc.) can be used to assist with the articulation. (e.g., motors, hand tools, mechanical tools, hydraulic devices, etc.) can be used to assist with the articulation.

[0065] FIG. 26 shows the modular space frame articulated to the appropriate location prior to the installation of the support platform 50 and any other pieces, as discussed herein. ​A new section or unit 115 of the frame support system 100 is shown. The mod ular space frame support system 100, removal of a portion of which can, in essence, be done by reversing the steps described above.

[0066] The modular space frame support system 100 described with reference to FIGS. 15-26 has individual sections or units 115 (and ultimately the work platform frame support system 200) that are square, i.e., each individual section or unit 115 is made up of four interconnecting structures 10 and four joists 30 as described above, although in some embodiments, the individual units 115 of the modular space frame support system 100 can take on different geometries and shapes. For example, FIGS. 27A, 27B, 27C, and 27D show various embodiments of the joist 30 and interconnecting structure 10 configuration. For example, FIG. 27D shows a "standard" length joist 30A (e.g., a nominal length of 8 feet) with two interconnecting structures 10A, 10B. This "standard" length joist 30A can be referred to as a "6 / 6 unit". FIG. 27C shows two equal length joists 30A, 30B connected to interconnecting structures 10 A, 10B, 10C. The joists 30A, 30B in FIG. 27C (each half the length of the joist 30A in FIG. 27D) can be referred to as "3 / 6 units" in that they are half the length of the above-described "6 / 6 unit". Similarly, two unequal length joists 30A, 30B are shown in FIG. 27B, each "2 / 6" respectively. in FIG. 27C (each half the length of the joist 30A in FIG. 27D) can be referred to as "3 / 6 units" in that they are half the length of the above-described "6 / 6 unit". Similarly, two unequal length joists 30A, 30B are shown in FIG. 27B, each "2 / 6" of the length of the joist 30A in FIG. 27D) can be referred to as "3 / 6 units" in that they are half the length of the above-described "6 / 6 unit". Similarly, two unequal length joists 30A, 30B are shown in FIG. 27B, each "2 / 6" unit. units respectively.​ can be referred to as a "2 / 6 unit" and a "4 / 6 unit". This is because the "2 / 6 unit" is approximately one-third of the length of a "standard" "6 / 6 unit" joist as shown in FIG. 27D, and similarly, the "4 / 6 unit" is approximately two-thirds of the length of the "6 / 6 unit". The same system is shown in FIG. 27A, where the first joist 30A is referred to as a "1 / 6 unit" and the second joist 30B is referred to as a "5 / 6 unit". As described above, by using joists 30 of different lengths and extending the joists 30 from the interconnecting structure 10 at different angles, a modular space frame support system 100 and a virtually infinite variety of configurations and installation areas of the resulting work platform system 200 can be obtained. For example, this versatility allows installers to fit the modular space frame support system 100 and the work platform system 200 around various obstacles (such as columns, gantries, abutments, etc.) and structures. The versatility allows installers to create a number of shapes for the work platform system in addition to just rectangles. Referring to the teachings herein (including at least FIGS. 14A, 17, and 22 - 26), it is apparent that at least one of the joists is connected to at least one of the interconnecting

[0067] structures using pins, providing free rotation of at least one joist with respect to at least one interconnecting structure around the pins. Yes. Moreover, it is clear that the free rotation is restricted by at least one of the following: i) additional pins that will be positioned close to the periphery of at least one interconnecting structure; and, ii) at least a portion of the work platform when the platform is positioned relative to the interconnecting structure and the joist in a final position.

[0068] Figures 28A and 28B show only plan views of two embodiments of the present invention. In these figures, it can be seen that the work platform support system 100 allows for various horizontal alignments. For example, FIG. 28A shows an 8-foot long joist 30 interconnected by a plurality of hubs 10. Due to the spacing between the pins 40 and the hubs 10, some flexibility is provided in the system 100 such that the system 100 can be curved (or "racked") horizontally. This helps to enable the system 100 to be installed around a structure. FIG. 28B shows an angled system 100. For example, the joist 30C connected to the hub 10C can be shorter than the joist 30B connected to the hub 10B. And the joist 30B is shorter than the joist 30A, which is connected to the hub 10A. In this way, by using joists 30A, 30B, 30C of different lengths and / or by changing the angle at which the joist 30 is connected to the hub 10, an angled system 100 as shown in FIG. 28B can be configured. ​ is possible. Similarly, this enables the system 100 to be installed around various obstacles and structures, for example.

[0069] FIG. 29 shows an elevation cross-sectional view of one embodiment, in which a support system 100 and a work platform system 120 are attached to a structure 90 via suspension connectors 80. In this embodiment, the structure 90 is a bridge 90. A plurality of beams 92 are below the bridge 90. A series of suspension connectors 80 (in this embodiment, high-strength chains) are attached to some of the beams 92 via structure attachment devices 82 (in this embodiment, standard beam clamps ). A plurality of handrail standards 85 are around the periphery of the work platform system 120, thereby creating a handrail system around the work platform system 120. A plurality of chains 80 are attached to various hubs 10 in the support system 100, thereby providing a structural connection to the bridge 90. Thus, the work platform system 1 20 and the support system 100 can be fully suspended from a suitable structure 90. Note that each hub 10 does not necessarily require a suspension connector 80 to be connected to the structure 90. For example, there is no suspension connector 80 connecting hub 10X to beam 92 X. This is because hub 10A is not aligned below beam 92X (or other suitable suspension point), and thus it may not be possible or desirable to use a chain 80 at that location . (or other suitable suspension point), and thus it may not be possible or desirable to use a chain 80 at that location because either it is not possible or it is not desirable. ​​

[0070] The suspension connector 80 can be any suitable support mechanism, and any suitable support mechanism can support both the work platform system 120 (and all associated static loads) and any intended dynamic loads applied on top of the work platform system 120. In fact, the work platform system 120 can support at least four times the intended dynamic loads that will be applied on top of the work platform system 120 in addition to its own weight. Similarly, the suspension connector 80 is also suitable for supporting at least four times the intended dynamic loads applied on it in addition to its own weight. The suspension connector 80 can be a high-strength chain or cable. For example, one suitable suspension connector 80 is a 3 / 8” grade 100 heat-treated alloy chain.

[0071] The suspension connector 80 is attached to a beam clamp 82, and the beam clamp 82 is further attached to a plurality of elements 92 on the lower side of the structure 90. The structure 90 can be a bridge, viaduct, or ceiling structure of a building, etc. Similarly, the element 92 to which the suspension connector 80 is attached can be a beam, joist, or any other suitable structural element of the structure 90. Instead of the beam clamp 82, other suitable structure attachment devices 82 can be used.

[0072] Figures 30A, 30B, 31A, and 31B all show the suspension connector 80 (for For example, it shows various diagrams of the interconnection between (such as a chain, a cable, etc.) and the hub 10. In the illustrated embodiment, the free end of the chain 80 (i.e., the distal end of the structure 90) is installed through the central opening area 19 of the upper element 11 of the hub 10. Then, the chain 80 is slid onto and into one of the four slots 17 (for example, 17A). When the chain 80 is installed in the slot 17A, the chain retainer pin 200 is installed in the adjacent transverse slot 18A so that the chain 80 remains held in the distal end of the slot 17A. When the keeper pin 200 is properly installed in the transverse slot 18A, the chain 80 and the slot 17A are sized and configured such that the chain 80 is effectively locked to the hub 10 and cannot slide out of its position in 17A (either vertically or horizontally). This locking system effectively fixes the hub 10 to the chain 80. As an additional safety check, a zip tie 201 can be installed between the hole 202 in the chain retainer pin 200 and the adjacent link in the chain 80. This further provides a visual aid to the installer and ensures that the chain retainer pin 200 is installed. An alternative device for connecting the suspension connector 80 to the work platform support system 100 is the auxiliary suspender mounting bracket 300. The auxiliary mounting bracket 300 is accessible for a particular hub 10 to connect with the suspension connector 80.

[0073] Typically used when it cannot be sess. Various FIGS. 32A, 32B , as shown in FIGS. 32C and 32D, one embodiment of the auxiliary suspender mounting bracket 300 includes two opposing parallel flanges 303. The interconnecting tube 3 04 and the base plate 302 span between the flanges 303. A plurality of mounting hole parts 305 pass through the base plate 302. The auxiliary suspender mounting bracket 300 can be used instead of or in addition to the hub 10 for the suspension point. The bracket 300 allows the suspension connector 80 to be connected to the system 100 at a location other than the hub 10.

[0074] For example, FIG. 33 shows a scenario that may typically be encountered when installing the work platform system 120. Note that FIG. 33 is not drawn to scale. One or more obstacles 95A can be located below the structure 90 or between the structure 90 and the work platform system 120. These obstacles 95A can be artificial or natural. For example, the obstacle 95A can be a concrete beam, a box beam, an inadequately sized framework, piping, lighting, and a finish surface, etc. The obstacle 95A makes a particular hub 10B impractical (or not possible) as a connection point of the system 120 to the suspension connector 80. In this case, one or more auxiliary suspender mounting brackets 300 can be attached to the joist 30. High-strength bolts (not shown) are passed through the mounting hole parts 305 and then the upper element 32 ​ Passed through the upper hole and can be connected to the bolt below the upper element 32 (for details of a similar connection, refer to the connection of the plate 60 in FIG. 19B). The suspension connector 80 (e.g., a chain) can be connected to the beam 92 via the beam clamp 82, and the beam 92 is located below the structure 90. As shown in FIG. 33, the obstacle 95B is directly above the hub 10B in the vertical direction,

[0075] thereby making the hub 10B insufficient as a suspension point. Therefore, the bracket 300 can be attached to the joist 30 adjacent to the hub 10B, thereby enabling the suspension connector 80 to obtain a proper attachment to the nearby beam 92. The angle Φ between the suspension connector 80 and the vertical direction (indicated by V) allows the suspension connector 80 to be non - vertical or to deviate slightly from the vertical direction.

[0076] FIGS. 34A, 34B, and 34C show elevation views of various embodiments, where the vertical flexibility of the present invention is evident. For example, FIG. 34A shows a part of the work platform system 120 suspended from the non - flat lower side of the structure 9 0 (e.g., an arch bridge). The suspension connector 80 and other connection details are not shown for clarity of illustration. Due to this design, there is flexibility in the interconnection between the hub 10 and the joist 30. This flexibility allows for some bending in the vertical direction (e.g., refer to FIG. 34A). This means that, for example, the system 120 ​​​​allows the underside of a curved arch bridge to be parallel (or "mirrored") do.

[0077] Alternatively, if the support structure 90 has a greater curvature, for example as shown in FIG. That is, multiple parts of the system 120 may be installed in the same It is not flat, but rather stepped or hierarchical. In this case, multiple hubs 10A, 10B may be mounted to the same pendant connector 80. A variety of such lengths of hanging connectors 80 can be installed so that As discussed above, the pendant connector 80 is inserted into slot 17 of the upper hub 10A. 1, and is then passed through the bottom opening 23 of the upper hub 10A and then It may also be connected to slot 17 of bus 10B (see, for example, FIGS. 30A and 30B).

[0078] As shown in FIG. 34C, another configuration of the present invention is to install the system 120 in a multi-level configuration. For example, perhaps the work involves vertical structures (e.g., bridge piers) If the system needs to be installed on a single platform, at least two systems 120A, 120B must be installed. Similar to the connection scenario used in FIG. 34B (above), a hanging connector can be used. The connector 80 can again be of any suitable length and is Passing from hub 10A on stem 120 to hub 10B on lower system 120; In this way, the multi-level system 120 may be mounted in a vertical orientation.
