Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of, and priority to, U.S. Provisional Patent Application No. 63 / 625,762, filed on Jan. 26, 2024, the entire contents of which are hereby incorporated herein by reference.BACKGROUNDTechnical Field

[0002] The present disclosure relates to accessibility systems and, more particularly, to wheelchair ramps and accessibility systems incorporating the same.Background of Related Art

[0003] Many personal residences, commercial establishments, government buildings, public facilities, and outdoor venues include accessibility systems to accommodate individuals that utilize wheelchairs or are otherwise physically impaired. In fact, in many cases, such accessibility systems are mandated by the Americans with Disabilities Act (ADA). Some of these accessibility systems are intended for permanent or long-term use, while others are for temporary or short-term use.

[0004] Regardless of whether the accessibility systems are required for long-term or short-term use, the manufacture, transportation, and installation of such systems can be challenging. For example, the various components of an accessibility system, e.g., platforms, ramps, and hand railings, may be welded together during manufacturing to form large, heavy, bulky subassemblies, thus making the transportation of these subassemblies from the manufacturing facility to the installation site difficult and expensive. In addition, the welding process itself requires a trained technician in order to ensure safety and effectiveness of the welds.

[0005] Systems that do not utilize significant amounts of welding to form subassemblies may instead rely on a variety of joint and connection parts to secure the various components of the accessibility system, e.g., platforms, ramps, and hand railings, to one another. However, the use of such joint and connection parts may overly complicate assembly and / or result in protruding areas, gaps, and / or other disturbances between the components, which could be a safety concern as well as unsightly.

[0006] Accordingly, there is a continuing need for wheelchair ramps and accessibility systems that facilitate simplified manufacturing, transportation, and on-site installation of such systems.SUMMARY

[0007] The present disclosure provides wheelchair ramps and accessibility systems that facilitate simplified manufacturing, transportation, and on-site installation of such systems.

[0072] Turning to FIG. 1, provided in accordance with the present disclosure is a modular accessibility system identified generally by reference numeral 10. Modular accessibility system 10 includes various aspects and features, detailed below. However, it is understood that the various aspects and features, although detailed with respect to modular accessibility system 10, need not necessarily be utilized together with one another and / or may find other application outside of modular accessibility system 10. Accordingly, modular accessibility system 10 is merely one exemplification of the aspects and features of the present disclosure.

[0073] Modular accessibility system 10 generally includes one or more platform assemblies 100, one or more ramp assemblies 200, one or more hand railing assemblies 300 supported by the platform assemblies 100 and / or ramp assemblies 200, and one or more legs 500 supporting the platform assemblies 100 and ramp assemblies 200.

[0074] Referring to FIGS. 2-4 and 6, a platform assembly 100 is described. Platform assembly 100 includes a plurality of platform panels 110 engaged with one another to define the usable, generally planar surface 102 of platform assembly 100, one or more connector panels 130 extending along sides of platform assembly 100, and a plurality of, e.g., four (4), corner brackets 150 disposed at the corners of platform assembly 100. As an alternative to one or more of the connector panels 130, platform assembly 100 may include one or more side rails (not shown, similar to side rail 270 of ramp assembly 200 (see FIG. 5)), extending along sides of platform assembly 100. As detailed below, in some configurations, connector panels 130 and the side rails may be different components or, in other configurations, may be the same component oriented differently to suit the application. For example, the connector panels 130 and side rails may be the same component wherein, for use as a connector panel 130 of platform assembly 100, the component is oriented right-side-up (see FIGS. 3 and 4) and, for use as a side rail, e.g., side rail 270 of ramp assembly 200, the component is oppositely oriented in an up-side-down orientation (see FIG. 5).

[0075] Each of the plurality of platform panels 110 may be monolithically formed as a single piece of material, e.g., via extrusion or other suitable process (although other manufacturing methods are also contemplated), defining an elongated strip-like configuration and including a plate portion 112, first and second connectors 114, 116 depending from plate portion 112 at opposing sides thereof, and one or more rib members 118 depending from plate portion 112 intermediate the opposing sides thereof. Platform panels 110 may define any suitable dimensions depending upon a particular purpose and any suitable number of platform panels 110 may be combined to define a planar surface 102 of platform assembly 100 of suitable dimensions, again depending upon a particular purpose.

[0076] The plate portion 112 of each platform panel 110 defines a generally planar configuration including an upper surface that forms part of generally planar surface 102 of platform assembly 100. More specifically, upon engagement of platform panels 110 with one another in side-by-side relation, as detailed below, plate portions 112 cooperate to define generally planar surface 102 of platform assembly 100. Each plate portion 112 may include ridges, protrusions, or other features defined on the upper surface thereof to facilitate traction on generally planar surface 102 of platform assembly 100.

[0077] First and second connectors 114, 116 extend along and depend from plate portions 112 at opposed sides thereof, as noted above. Each first connector 114 defines a generally n-shaped configuration having three sides and a downwardly-facing opening. Each second connector 116, on the other hand, defines a generally u-shaped configuration having three sides and an upwardly-facing opening. Each first connector 114 further includes a tongue 115 extending partially across the downwardly-facing opening thereof, and each second connector 116 further defines a groove 117 on the side opposite the upwardly-facing opening thereof.

[0078] The above-detailed configurations of first and second connectors 114, 116 enable engagement of the first connector 114 of a platform panel 110 with the second connector 116 of an adjacent platform panel 110 to engage the adjacent platform panels 110 with one another. More specifically, each first connector 114 is fit within the adjacent second connector 116 with the tongue 115 received within the groove 117 to engage the adjacent platform panels 110 with one another. Further, the inter-fit n-shaped and u-shaped first and second connectors 114, 116, respectively, cooperate to define a screw boss 120 of appropriate dimensions to be capable of receiving and securing therein a fastener, e.g., a screw “S,” as detailed below.

[0079] Each rib member 118 of each platform panel 110 depends from the plate portion 112 thereof intermediate the opposing sides of the platform panel 110, as noted above. Each rib member 118 may define a c-shaped channel 119 of appropriate dimensions to serve as a screw boss capable of receiving and securing therein a screw “S,” as detailed below.

[0080] Continuing with reference to FIGS. 2-4 and, each connector panel 130 of platform assembly 100 extends along a side of platform assembly 100. Each connector panel 130 may be monolithically formed as a single piece of material defining an elongated strip-like configuration, although other configurations are also contemplated. Each connector panel 130 includes a plate portion 132 defining an elongated strip-like configuration, and a web 134 depending from an underside of plate portion 132, extending therealong, and oriented substantially perpendicularly relative to plate portion 132 so as to define a generally T-shaped configuration therewith.

[0081] The plate portion 132 defines a generally planar configuration and is configured to abut, overlay, or underlay the plate portion 112 of one or more platform panels 110 to serve as an extension of planar surface 102 of platform assembly 100 along a side thereof. The plate portion 132 may include ridges, protrusions, or other features configured to facilitate traction, similarly as with plate portions 112 of platform panels 110.

[0082] The web 134 of each connector panel 130, as noted above, depends from an underside of the plate portion 132 thereof, extends therealong, and is oriented to define a generally T-shaped configuration therewith. However, the web 134 is offset towards one side of plate portion 132 such that plate portion 132 includes a wide segment 133a on one side of web 134 and a narrow segment 133b on the other side of web 134. Web 134 includes a body 136 which may include a plurality of spaced-apart screw apertures defined therethrough and is configured to define the upright portion of the generally T-shape of web 134 and plate portion 132. Web 134 further includes an upper c-shaped channel 138 disposed at one end of body 136, depending from an underside of the narrow segment 133b of plate portion 132, and oriented such that the opening in the upper c-shaped channel 138 faces downwardly; and a lower c-shaped channel 139 disposed at the other end of body 136 and oriented such that the opening in the lower c-shaped channel 139 faces upwardly, opposing the opening of upper c-shaped channel 138.

[0083] As best illustrated in FIG. 4, in order to engage a connector panel 130 alongside the platform panels 110, the connector panel 130 is positioned such that wide segment 133a of plate portion 132 abuts, overlays, or underlays the ends of plate portions 112 of platform panels 110. Screws “S” may then be inserted through the spaced-apart screw apertures and into engagement within the c-shaped channels 119 of rib members 118 of platform panels 110 and / or the screw bosses 120 formed by the first and second connectors 114, 116 of adjacent platform panels 110 to thereby secure connector panel 130 in position extending along the sides of the platform panels 110 such that the plate portion 132 of connector panel 130 serves as an extension of planar surface 102 of platform assembly 100. With respect to engagement of fasteners, e.g., screws “S,” within the screw bosses 120 formed by the first and second connectors 114, 116 of adjacent platform panels 110, not only does this secure the connector panel 130 to the platform panels 110, but the engagement of screws “S” within screw bosses 120 may also serves to lock the adjacent platform panels 110 in engagement with one another, inhibiting disengagement of the first and second connectors 114, 116 from one another.

[0084] Referring back to FIGS. 2 and 3, corner brackets 150 are disposed at the corners of platform assembly 100. Each corner bracket 150 includes a body 152 defining a vertically-oriented passageway 154 having a rectangular cross-section (although other configurations are also contemplated) and configured to receive a leg 500 to support platform assembly 100 off the ground. The leg 500 may be engaged within passageway 154 by set screws 155 extending through a corner of body 152 into passageway 154, although other positions of set screws 155 and / or other suitable mechanisms for retaining leg 500 are also contemplated. As can be appreciated, set screws 155 (or another mechanism, if so provided) may be adjustable to vary a position of leg 500, thereby varying a height of platform assembly 100 relative to the ground. Each corner bracket 150 further includes a pair of flanges 156, 158 extending therefrom and may be disposed in perpendicular orientation relative to one another. Flanges 156, 158 each define one or more screw apertures enabling fasteners, e.g., screws “S” to be inserted therethrough and into upper and lower c-shaped channels 138, 139 of connector panels 130 on either side of the corner bracket 150 to secure the connector panels 130 to one of the corner brackets 150 at each corner of platform assembly 100. As can be understood, the upper and lower c-shaped channels 138, 139 of connector panels 130 may also be configured to serve as screw bosses.

[0085] With momentary reference to FIG. 5, as noted above, as an alternative to one or more of connector panels 130, one or more side rails may be utilized along one or more sides of a platform assembly 100, similarly as detailed below and illustrated in FIG. 5 with respect to side rails 270 of platform assembly 200. Connector panels 130 may be utilized on a side of platform assembly 100, for example, where another surface-defining assembly, e.g., another platform assembly 100, a ramp assembly 200, etc. (see FIG. 1), is desired to be connected to that side of platform assembly 100. The side rails, on the other hand, may be utilized on a side of platform assembly 100 where no further surface-defining assemblies are intended to be joined but rather, only legs 500 and / or hand railing assemblies 300 are to be attached. Each side rail may be configured similarly to the connector panels 130 or, as mentioned above, these may be the same component, just oriented differently depending upon whether use as a connector panel 130 or side rail.

[0086] Turning to FIG. 6, as noted above, one or more hangers 180 may be operably coupled with a connector panel 130 to enable attachment of another component with platform assembly 100, for example, a ramp assembly 200 (FIGS. 7-15) (although another platform assembly 100 (FIG. 1) or other surface-defining assembly is also contemplated), with connector panel 130 serving as the bridge between the platform assembly 100 and ramp assembly 200. Each hanger 180 includes a base or back panel 182 and a saddle 184 extending from the back panel 182 generally perpendicularly therefrom. Back panel 182 includes an upper end defining a first flange or guide rail 186 and a lower end defining a second flange or guide rail 187. An extension 188 extends from back panel 182 in a direction opposite the direction saddle 184 extends. Saddle 184 defines a receiving area 185 and includes a clamp screw 189 that is selectively extendable into and withdrawable from receiving area 185.

[0087] In order to operably couple a hanger 180 to a connector panel 130, the hanger 180 is positioned such that first and second guide rails 186, 187 are aligned with the open ends of upper and lower c-shaped channels 138, 139, respectively, of the connector panel 130, and is slid relative thereto such that first and second guide rails 186, 187 are slidably received within upper and lower c-shaped channels 138, 139, respectively. Extension 188 of hanger 180 may ensure appropriate spacing between back panel 182 of hanger 180 and body 136 of web 134 of connector panel 130 to permit hanger 180 to slide along connector panel 130 without interference from the screw heads of screws “S.” Any suitable number of hangers 180 may be operably coupled to connector panel 130 in this manner and slid to suitable positions depending upon, for example, the component to be engaged to the connector panel 130. As an alternative to the above, hanger 180 can be maneuvered into position similarly as detailed below with respect to bracket 400 (FIGS. 16-24). More specifically, hanger 180 may be oriented such that first and second guide rails 186, 187 extend vertically and, thereafter, hanger 180 may be inserted transversely into web 134 of connector panel 130 between upper and lower c-shaped channels 138, 139. Once hanger 180 is in this position, hanger 180 is rotated such that first and second guide rails 186, 187 are horizontally-oriented. As hanger 180 is rotated in this manner, first and second guide rails 18, 187 are inserted into engagement within upper and lower c-shaped channels 138, 139 to achieved the engaged configuration detailed above. In yet another alternative, first guide rail 186 is first inserted into upper c-shaped channel 138 with the remainder of hanger 180 angling outwardly from web 134 of connector panel 130. Thereafter, second guide rail 187 is maneuvered and / or web 134 manipulated such that second guide rail 187 is positioned above lower c-shaped channel 139 and dropped down into engagement within lower c-shaped channel 139. The reverse is also contemplated, e.g., wherein second guide rail 187 is first engaged within lower c-shaped channel 139 and thereafter first guide rail 186 maneuvered and / or web 134 manipulated to engage first guide rail 186 within upper c-shaped channel 138.

[0088] Referring to FIGS. 7-15, as noted above, a ramp assembly 200 may be engaged to platform assembly 100 via connector panel 130 and one or more hangers 180. Ramp assembly 200 may include a plurality of ramp panels 210 engaged with one another and arranged transversely with respect to a length of ramp assembly 200. Ramp panels 210 may be similar to platform panels 110 (FIGS. 2-6) and, in some configurations, may be the same component just cut to a different length depending on the desired width of the ramp assembly 200. The ramp panels 210 may be engaged with one another in a similar manner as with platform panels 110 to achieve a desired length of ramp assembly 200. Each ramp panel 210 generally includes a plate portion 212, a first connector 214 along a first side of the plate portion 212, a second connector 216 along a second side of the plate portion 212, and a rib member 218 extending along plate portion 212 at an intermediate position between first and second connectors 214, 216. Rib member 218 may define a c-shaped channel 219 which serves as a screw boss capable of receiving and securing therein a screw “S,” as detailed above. Ramp panels 210 may further define a c-shaped channel 217a on a rib member 217b extending from first and / or second connectors 214, 216. For example, as illustrated in FIGS. 10-12, second connector 216 may include a rib member 217b extending downwardly therefrom and including a c-shaped channel 217a defined on rib member 217b. More specifically, the rib member 217b of the end ramp panel 210 of ramp assembly 200 may define a more robust configuration, including an increased thickness, to increase strength at the joint between ramp assembly 200 and platform assembly 100 and or to increase strength at the joint between ramp assembly 200 and ramp assembly 200 as illustrated in FIGS. 14 and 15. A c-shaped channel 217a may be disposed on the increased-thickness rib member 217b, and / or may be defined on any other ramp panel 210 at either end thereof. Platform panels 110 (FIGS. 2-4) may be formed in a similar manner.

[0089] With additional reference to FIG. 5, ramp assembly 200 may also include side rails 270. As noted above, similar side rails 270 may be utilized to engage platform panels 110 along the sides of platform assembly 100 (see FIG. 5) and, in some configurations, the side rails may be the same component, cut to a desired length. Further, as also noted above, side rails 270 may be the same component as the connector panels130, but in an up-side-down orientation, or may be different components.

[0090] Side rails 270 each include a plurality of screw apertures 271 and upper and lower opposed c-shaped channels 274 (only the lower c-shaped channel 274 is visible in FIG. 5). Screw apertures 271 enable fasteners, e.g., screws “S,” to be inserted through side rails 270 and into engagement within the c-shaped channels 219 of rib members 218 of ramp panels 210 and / or the screw bosses 220 formed by the first and second connectors 214, 216 of adjacent ramp panels 210 to thereby secure the side rail 170 in position extending along the ends of the ramp panels 210. Upper and lower opposed c-shaped channels 274 (only the lower c-shaped channel 274 is visible in FIG. 5) are similar in configuration and function as those of webs 134 of connector panels 130 (see FIGS. 3, 4, and 6) and, as noted above, may be the same component turned up-side-down.

[0091] With more particular reference to FIGS. 7-11, and initially to FIGS. 7-9, in order to engage ramp assembly 200 with platform assembly 100 via connector panel 130 and hangers 180, the ramp assembly 200 is maneuvered such that the rib member 217b extending downward from the exposed first connector 214 of the end ramp panel 210 of ramp assembly 200 (although it could also be the rib member (not shown) extending downward from the exposed second connector 216 of the other end ramp panel 210 of ramp assembly 200, if ramp assembly 200 were oriented oppositely), is seated at least partially within the receiving area 185 of the saddle 184 of each of the hangers 180. With reference to FIGS. 10 and 11, once the rib member 217b is seated within saddles 184, the clamp screw 189 of each saddle 184 may be sufficiently tightened, e.g., sufficiently extended into receiving area 185, such that each clamp screw 189 is urged into the rib member 217b of the first connector 214 to retain the ramp panel 210 in position, thereby engaging ramp assembly 200 in abutment with connector panel 130.

[0092] As illustrated in FIG. 12, engagement between ramp assembly 200 and connector panel 130 can be further secured, in the vertical direction in particular, via tucking first connector 214 underneath the narrow segment 133b of plate portion 132 of connector panel 130 to establish a tongue and groove engagement similarly as detailed above with respect to the engagement of first and second connectors 114, 116 of platform panels 110 of platform assembly 100 (see FIGS. 3 and 4). Once this position is achieved, each clamp screw 189 may be tightened as noted above to secure the engagement between the ramp assembly 200 and the connector panel 130.

[0093] Referring to FIGS. 13, 14 and 15, multiple ramp assemblies 200 may be engaged with one another with the adjacent end ramp panels 210 of each ramp assembly 200 being engaged similarly as detailed above with respect to engagement of platform panels 110 of platform assembly 100 with one another (see FIGS. 3 and 4). That is, the first connector 214 of the end ramp panel 210 of one of the ramp assemblies 200 is fit within the adjacent second connector 216 of the end ramp panel 210 of the other ramp assembly 200 to engage the ramp assemblies 200 and define screw bosses 220. A fastener, e.g., a screw “S” (FIG. 4), alone or inserted through a side rail 270, may be engaged within the screw boss 220 to secure the ramp assemblies 200 to one another. Alternatively, as illustrated in FIGS. 14 and 15, another fastener, e.g., a set screw “SS,” may be engaged within the screw boss 220 to secure the ramp assemblies 200 to one another.

[0094] Turning to FIGS. 16-24, as noted above, modular accessibility system 10 includes one or more hand railing assemblies 300 supported by the platform assemblies 100 and / or ramp assemblies 200, and one or more legs 500 supporting the platform assemblies 100 and ramp assemblies 200. In order to enable efficient and effective attachment of hand railing assemblies 300 and / or legs 500 to platform assemblies 100 and / or ramp assemblies 200, brackets 400 are provided. More specifically, brackets 400 are configured for operable coupling with side rails 270 of platform assemblies 100 and / or ramp assemblies 200, respectively. Thus, although brackets 400 are detailed below with respect to engagement with a side rail 270 of a ramp assembly 200, it is understood that the below similarly applies to the engagement of brackets 400 with the side rails of platform assemblies 100 and / or the connector panels 130 of platform assemblies 100.

[0095] Referring to FIGS. 17-20, each bracket 400 includes a base 410 including first and second flanges 412, 414 extending from opposing ends thereof. Each bracket 400 further includes a u-shaped frame 420 monolithically formed with or otherwise engaged to base 410 to define a generally rectangular passageway 430 extending through bracket 400. First and second vertically-spaced clamp screws 440, 450 are operably engaged with u-shaped frame 420 and configured for selective extension into and withdrawal from passageway 430, independently of one another.

[0096] With continued reference to FIGS. 17-20, in order to engage a bracket 400 within a side rail 270, the bracket 400 is first rotated to a horizontal orientation wherein flanges 412, 414 are horizontally-oriented. In this position, bracket 400 may be inserted transversely into side rail 270 between the upper and lower c-shaped channels 272, 274, respectively, thereof. Once inserted in this manner, bracket 400 is rotated back to a vertical orientation wherein flanges 412, 414 are vertically-oriented and extend through the slots defined within upper and lower c-shaped channels 272, 274 into upper and lower c-shaped channels 272, 274, respectively. In this manner, bracket 400 is inhibited from being removed from side rail 270, but may freely slide therealong, at least at this point.

[0097] Turning to FIGS. 21-22, to engage a leg 500 with bracket 400, for example, leg 500 is inserted vertically through passageway 430 to a desired position, for example, depending upon the desired height of ramp assembly 200 at that location. Once the desired position has been reached, clamp screws 440, 450 are tightened against leg 500 to retain leg 500 in the desired position. The tightening of clamp screws 440, 450 also serves to urge leg 500 into contact with side rail 270 in press-fit engagement therewith, thereby inhibiting bracket 400 from sliding along side rail 270. The brackets 400 ability to slide along and rotate relative to the side rail 270 makes it easily adjustable. When installing a ramp for example this versatility allows adjustment, which can accommodate varying degrees of slope (e.g., 0° to 450 or more specifically a 4.8 degree angle; 8.3% grade as is regulated for hand-propelled wheelchair and / or 7.1 degree angle; 12.5% grade as is regulated for powered wheelchairs) as well as repositioning a leg 500 along the length of a ramp to accommodate for terrain variations or obstacles encountered during an installation.

[0098] Referring to FIGS. 23 and 24, to engage a hand railing assembly 300 with bracket 400, a post assembly 310 of the hand railing assembly 300 is inserted vertically through passageway 430 to a desired position, similarly as detailed above with respect to the engagement of leg 500 (FIGS. 21 and 22). Alternatively, second clamp screw 450 may be sufficiently extended into passageway 430 such that the post assembly 310 may be inserted into passageway 430 and sit atop the portion of second clamp screw 450 extending into passageway 430. In this manner, the hand railing assembly 300 may be assembled before being fully engaged with bracket 400, whereby second clamp screw 450 is withdrawn and post assembly 310 moved to the desired final position before tightening first clamp screw 440 and re-tightening second clamp screw 450 against post assembly 310. Additionally or alternatively, a pin “P” or other suitable structure protruding from post assembly 310 may contact bracket 400 to set a depth of insertion of post assembly 310 into bracket 400. In either configuration, once the desired final position of post assembly 310 has been achieved, clamp screw 440 and / or clamp screw 450 may be tightened against post assembly 310 to retain post assembly 310 in the desired position while also inhibiting bracket 400 from sliding along side rail 270, similar to engaging the leg 500, as detailed above.

[0099] Turning now to FIGS. 25-48, hand railing assemblies 300 provided in accordance with the present disclosure and configured for use with modular accessibility system 10 (FIG. 1) or independently thereof are described. The hand railing assemblies 300 may take various forms depending upon particular needs. Some of such configurations are detailed below, although other configurations are also contemplated.

[0100] With initial general reference to FIGS. 25-27, each hand railing assembly 300 generally includes one or more post assemblies 310, one or more intermediate rails 330, and one or more end rails 350. Curved connector rails 370 (FIGS. 26 and 40) and / or pivoting connectors 390 (FIGS. 41 and 42) may also be provided. Additionally or alternatively, spindles 600 (FIGS. 43-47), obstruction panels 700 (FIGS. 43-47), and / or projection surfaces 800 (FIG. 48) may be provided.

[0101] Referring to FIGS. 27-35, each post assembly 310 may includes first and second post components 312, 314 configured to engage one another in inter-fit manner, as detailed below. First and second post components 312, 314 each define a plate-like configuration including opposing sides and may each be formed as a single, monolithic component. Generally flat surfaces 316, 318 are defined on the outwardly-facing sides of first and second post components 312, 314, respectively, while a plurality of spaced-apart ribs 320, 322 which in FIGS. 30-33 appear similar to fingers that extend from the inwardly-facing sides of first and second post components 312, 314, respectively. Ribs 320 of first post component 312 are offset relative to ribs 322 of second post component 314 to enable post components 312, 314 to engage one another with ribs 320, 322 in an inter-fit manner such that first and second post components 312, 314 are laterally fixed relative to one another. As illustrated in FIGS. 30 and 31, this may be sufficient to engage first and second post components 312, 314 with one another. Alternatively, as illustrated in FIGS. 32 and 33, some ribs 320, 322, e.g., the outer-most ribs, of first and second post components 312, 314 may include complementary snap-fit features 321a, 321b and recesses 323a, 323b, e.g., corresponding protrusions and recesses, to further engage first and second post components 312, 314 in snap-fit manner in addition to the inter-fit engagement therebetween. First and second post components 312, 314 may be the same component, e.g., two of the same component oriented to face one another. Alternatively, first and second post components 312, 314 may be different from one another, e.g., one being a male component and the other a complementary female component.

[0102] Referring to FIGS. 34 and 35, in configurations where only inter-fit engagement is provided between first and second post components 312, 314 (see FIGS. 30 and 31), a bolt “B” and nut “N” may be utilized to secure first and second post components 312, 314 with one another. With respect to embodiments where snap-fit engagement is also provided, bolt “B” and nut “N” need not be utilized, but may, if so desired.

[0103] Continuing with reference to FIG. 35, first and second post components 312, 314 each further defines one or more sets of apertures 325, 327, respectively, which may be configured to align with one another upon engagement of first and second post components 312, 314. Each post component 312, 314 may include multiple sets of aperture 325, 327, which may be located at various positions along the length thereof. For example, first sets of aperture 325, 327 may be disposed at the upper ends of first and second post components 312, 314, second sets of apertures 325, 327 may be disposed towards but spaced-apart from the upper ends of first and second post components 312, 314, and / or third sets of apertures 325, 327 may be disposed towards but spaced-apart from the lower ends of first and second post components 312, 314 (see FIGS. 43, 45, and 47).

[0104] As illustrated in FIG. 35, each set of apertures 325, 327 of the first and second post components 312, 314, respectively, includes three apertures 326a, 326b, 326c and 328a, 328b, 328c disposed in vertical registration with one another. However, it is also contemplated that other suitable arrangements be provided, e.g., different numbers of apertures and / or different orientations thereof such as horizontal registration. One or more of the aperture 326a, 326b, 326c and 328a, 328b, 328c of each of the first and second post components 312, 314, respectively, is configured to receive a screw “S” therethrough, wherein the heads of the screws “S” are disposed on the inwardly-facing sides of first and second post components 312, 314, respectively, and the shanks of the screws “S” extend through first and second post components 312, 314 and outwardly from the outwardly-facing sides thereof. As detailed below, such a configuration enables engagement of screws “S” with intermediate rails 330, end rails 350, and / or other suitable rails. Pockets 329 surrounding sets of apertures 325, 327 may be defined within one or more of ribs 320, 322 of first and second post components 312, 314 to accommodate the heads of screws “S” when first and second post components 312, 314 are engaged with one another. Pockets 329 my be a feature that is molded into the first and second post components 312, 314 or may be created by removing of a portion (e.g., by a machining operation) of one or more ribs as can be seen in FIG. 35.

[0105] Turning to FIGS. 35 and 36, each rail component configured for use with hand railing assembly 300, e.g., intermediate rails 330, end rails 350, and curved connector rails 370, includes a tube segment of similar configuration and is configured to engage post assemblies 310 in a similar manner. Thus, although described in detail below with respect to intermediate rails 330, it is understood that the following applied similarly to end rails 350 and curved connector rails 370, except as specifically contradicted hereinbelow. Further, although detailed and illustrated herein as being circular in cross-section, the tube segments may alternatively define oval, square, or other suitable cross-sectional configurations, depending upon a particular purpose.

[0106] Intermediate rails 330 each include an outer tube 332 defining a hollow interior 334 extending longitudinally therethrough and a web 336 disposed within hollow interior 334. Each intermediate rail 330 may be monolithically formed as a single piece of material, e.g., via extrusion or other suitable process. Web 336 extends across hollow interior 334 and is connected with outer tube 332, on an inner surface of outer tube 322, at opposing ends of web 336. Web 336 defines a plate-like portion 338 and a set of c-shaped channels 340 disposed on plate-like portion 338. For example, the set of c-shaped channels 340 may include three (3) aligned c-shaped channels 342, 344, 346, although other suitable configurations and / or numbers of channels are also contemplated. C-shaped channels 342, 344, 346 define screw bosses 343, 345, 347, respectively, of appropriate dimensions to enable receipt of the shanks of the screws “S” engaged with post assembly 310, as detailed below. C-shaped channels 324, 344, 346 may share walls with adjacent C-shaped channels 324, 344, 346. Instead of C-shaped channels 342, 344, 346, other suitable structure forming screw bosses 343, 345, 347 for the receipt of the shanks of the screws “S” or other fasteners are also contemplated. The C-shaped channels 342, 344, 346, may be positioned adjacent to or remote from the outer tube 322. In some applications it may be desirable to space the C-shaped channels 342, 344, 346 away from the outer tube 322 enough e.g., on web 336) so that the heads of the screws “S” will be hidden from view in the final assembly (e.g., at the top of the post assemblies 310). In this way the pocket 329 will have ribs 320, 322 on all four sides (e.g., above, below, right side and left side) as can be seen in FIG. 35. This configuration will allow the screws “S” to be obscured from view in the final assembly as can be seen in FIG. 29.

[0107] Plate-like portion 338 of web 336 may extend across hollow interior 334 of outer tube 332 at a position off-center therefrom such that the c-shaped channels 342, 344, 346 may be centered or positioned on a center line relative to outer tube 332, e.g., aligned on a diameter thereof. Additionally or alternatively, plate-like portion 338 of web 336 may be aligned on the neutral plane of outer tube 332, as detailed below with respect to end rails 350 (FIGS. 37-39).

[0108] Referring again to FIGS. 28, 29, and 34-36, in order to couple intermediate rails 330 to one another in end-to-end fashion with post assemblies 310 disposed therebetween, the generally flat surface 316 of the first post component 312 is abutted against the end of one of the intermediate rails 330 such that one set of apertures 325 of first post component 312 is aligned with the set of c-shaped channels 340 of the intermediate rail 330. Thereafter, one or more screws “S” may be inserted through one or more apertures 326a, 326b, 326c of the set of apertures 325 and into engagement within the aligned c-shaped channels 342, 344, 346 of the set of c-shaped channels 340 to engage first post component 312 with the intermediate rail 330. The particular number of screws “S” utilized may depend on a particular purpose or preference. For example, two screws “S” may be utilized and engaged with the outer apertures 326a, 326c and outer c-shaped channels 342, 346 (as illustrated), a single center screw “S” may be utilized, three screws “S” may be utilized, etc.

[0109] Next, the generally flat surface 318 of the second post component 314 is abutted against the end of the other intermediate rail 330 such that one set of apertures 327 of second post component 314 is aligned with the set of c-shaped channels 340 of the intermediate rail 330 and screws “S” are inserted therethrough to engage second post component 314 with the intermediate rail 330, similarly as detailed above. Once first and second post components 312, 314 are each engaged with one of the intermediate rails 330, the first and second post components 312, 324 may be engaged with one another, as detailed above, to thereby couple intermediate rails 330 to one another in end-to-end fashion with the post assembly 310.

[0110] Intermediates rails 330 may be provided singularly between post assemblies 310, in pairs, e.g., as illustrated in FIGS. 25-27, wherein each pair of intermediate rails 330 includes upper and lower closely-spaced intermediate rails 330 extending generally parallel to one another between post assemblies 310 or as illustrated in FIGS. 40-47 wherein each pair of intermediate rails 330 includes upper and lower further-spaced intermediate rails 330 extending generally parallel to one another between post assemblies 310, or maybe provided in sets of any suitable number.

[0111] Turning now to FIGS. 37-39, an end rail 350 is illustrated including a curved configuration such that first and second ends 351a, 351b of the end rail 350 are oriented in similar directions. Plate-like portion 358 of web 356 of end rail 350 may be aligned on the neutral plane “NP-NP” of outer tube 332. The neutral plane “NP-NP” is the plane in which a tube, when loaded by a bending force, is not under stress. The material on one side of the neutral plane “NP-NP” (the outer portion of the bend) is in tension as a result of the bending force, and the material on the other side of the neutral plane “NP-NP” (the inner portion of the bend) is in compression as a result of the bending force. Providing the plate-like portion 358 of the web 356 on the neutral plane “NP-NP” eliminates stress from being imparted thereto despite the bend in the end rail 350. Indeed, providing a plate-like portion of the web on any curved component, e.g., end rail 350 or curved connector rail 370, reduces stress therein, as detailed above, regardless of the particular curve configuration. End rails 350 may define any suitable shape, bend angle, or other configuration. Referring to FIG. 40, hand railing assembly 300 is shown including a pair of curved connector rails 370 connected to adjacent intermediate rails 330 via post assemblies 310. Curved connector rails 370 may define any suitable bend angle, e.g., 30, 45, 60, 90, or 180 degrees, depending on a particular purpose.

[0112] In some configurations, the intermediate rails 330, end rails 350, and curved connector rails 370 are initially formed from the same component and thereafter bent and / or cut to achieve the desired configuration.

[0113] With reference to FIGS. 41 and 42, pivoting connectors 390 are illustrated. Each pivoting connector 390 includes first and second tube segments 392, 394 interconnected by a pivot joint 396. One or more screw shanks “SSS” extends from each of the first and second tube segments 392, 394 to enable attachment of the pivoting connector 390 to an intermediate rail 330 or other rail component at either end thereof, e.g., via engagement of each screw shank “SSS” within one of the c-shaped channels 342, 344, 346 of the web 336 of the intermediate rail 330 or other rail component. Pivoting connectors 390 enable of the components on either side thereof after-assembly, to achieve a desired configuration.

[0114] Turning to FIGS. 43-47, any of the rail components such as, for example, intermediate rails 330 may include attachment features to enable attachment of, e.g., spindles 700 or obstruction panels 800. More specifically, spaced-apart aperture 710 may be defined within upper and lower intermediate rails 330 to enable receipt of a plurality of spaced-apart spindles 700 therebetween. Additionally or alternatively, channels 810 recessed into the exterior surface of outer tubes 332 (formed therein during extrusion of the intermediate rails) of upper and lower intermediate rails 330 may be provided for receipt of an obstruction panel 800, e.g., a sheet of glass, metal, plywood, metal, plastic, etc.

[0115] As illustrated in FIG. 48, any of the rail components such as, for example, intermediate rails 330, end rails 350, and curved connector rails 370 (as illustrated) may include features such as a projection surface 900 for example a rib, web or fin, extending therefrom, which may also be formed during extrusion, may be attached to the curved connector rail 370 in any suitable manner, or may be otherwise formed. The projection surface 900 may be disposed on the neutral plane of intermediate rails 330, end rails 350, and curved connector rail 370, providing a similar benefit when it comes to bending the rail component, as detailed above. Rail components which include such a projection 900 enable spindles 700 and / or obstructions 800 to be attached directly to the projection 900. Although, rail components which include such a projection 900 may also include features, such as apertures and / or channels, to enable spindles 700 and / or obstructions 800 to be attached in the manner detailed above.

[0116] Turning to FIGS. 49-51, another modular accessibility system provided in accordance with the present disclosure is shown generally identified by reference numeral 1010. To the extent consistent and except as explicitly contradicted below, modular accessibility system 1010 may include any or all of the aspects and features of system 10 (FIG. 1), as detailed above. Accordingly, only differences between system 1010 and system 10 (FIG. 1) are described in detailed below while similarities are summarily described or omitted entirely for purposes of brevity. Further, the aspects and features of system 1010 detailed below are also contemplated for use in other modular accessibility systems; accordingly, modular accessibility system 1010 is merely one exemplification of the aspects and features of the present disclosure.

[0117] Modular accessibility system 1010 is shown in FIGS. 49-51 including one or more platform assemblies 1100 (one platform assembly 1100 is shown in FIG. 49), one or more ramp assemblies 1200 (first and second ramp assemblies 1200 are shown in FIG. 49), one or more hand railing assemblies each including a corner post 1301 (see hand railing corner post 1301 in FIGS. 61 and 62) supported by the platform assembly 1100, and one or more legs 1500 (four legs 1500 are shown in FIG. 49) supporting the platform assembly 1100.

[0118] Platform assembly 1100 includes a plurality of platform panels 1110 engaged with one another as detailed above, one or more connector panels 1130 extending along one or more sides of platform assembly 1100, and a plurality of, e.g., four (4), corner brackets 1150 disposed at the corners of platform assembly 1100. As an alternative to or in addition to the one or more connector panels 1130, platform assembly 1100 may include one or more side rails extending along one or more sides of platform assembly 1100. As detailed below, in some configurations, connector panels 1130 and the side rails may be different components or, in other configurations, may be the same component oriented differently to suit the application. For example, the connector panels 1130 and side rails may be the same component wherein and only differentiated based upon whether the component is used for connection of a ramp assembly 1200 (and, thus, is a connector panel 1130) or whether the component functions as a side rail (and, thus, is a side rail).

[0119] Referring also to FIGS. 52-54, each connector panel 1130 of platform assembly 1100 extends along a side of platform assembly 1100. Each connector panel 1130 may be monolithically formed as a single piece of material defining an elongated strip-like configuration, although other configurations are also contemplated. Each connector panel 1130 includes a plate portion 1132 defining an elongated strip-like configuration, and a web 1134 depending from an underside of plate portion 1132, extending therealong, and oriented substantially perpendicularly relative to plate portion 1132 so as to define a generally T-shaped configuration therewith.

[0120] The plate portion 1132 of each connector panel 1130 defines a generally planar configuration and serves as an extension of the planar surface defined by platform panels 1110 of platform assembly 1100. The web 1134 of each connector panel 1130, as noted above, depends from an underside of the plate portion 1132 thereof to define a generally T-shaped configuration therewith. Web 1134 includes a body 1136, an upper c-shaped channel 1138 disposed towards one end of body 1136 (e.g., closer to the plate portion 1132) and extending along the length of body 1136, a lower c-shaped channel 1139 disposed at the opposite end of body 1136 (e.g., the free end of body 1136) and extending along the length of body 1136, and a connector 1140 disposed outwardly of upper c-shaped channel 1138 (e.g., further from body 1136) at the end of body 1136 and extending along the length of body 1136. Upper and lower c-shaped channels 1138, 1139 define open portions that face one another. Connector 1140 defines a hook having a substantially “u” shaped channel wherein the opening thereof faces generally upwardly towards the plate portion 1132. Further, upper and lower c-shaped channels 1138, 1139, at the ends thereof, may form a screw boss and are configured to receive fasteners, e.g., bolts, screws, etc., to secure connector panel 1130 between first and second corner brackets 1150 (see also FIG. 61). Web 1134 also includes a flange 1135, e.g., extending substantially perpendicularly from body 1136 in an opposite direction from upper and lower c-shaped channels 1138, 1139. Flange 1135 is spaced from plate portion 1132 and cooperates with plate portion 1132 and body 1136 to define a generally “U” or “J” shaped channel 1137.

[0121] Turning back to FIGS. 49-51, first and second ramp assemblies 1200 are configured to connect to connector panels 1130 on opposing sides of platform assembly 1100. Ramp assemblies 1200 are similar to and may include any of the aspects and features of ramp assemblies 200 (FIG. 1) detailed above. In aspects, ramp assemblies 1200 are identical to ramp assemblies 200 (FIG. 1). As detailed above with respect to ramp assemblies 200 (FIG. 1), each ramp assembly 1200 includes a plurality of ramp panels 1210 wherein each ramp panel 1210 includes a plate portion 1212, a first connector 1214 extending along a first side of the plate portion 1212, a second connector 1216 extending along a second side of the plate portion 1212, and a rib member 1218 extending along plate portion 1212 at an intermediate position between first and second connectors 1214, 1216. The first connector 1214 of each ramp panel 1210 of each ramp assembly 1200 defines a hook having a substantially “n” shaped channel such that the opening thereof faces downwardly away from the plate portion 1212 while the second connector 1216 of each ramp panel 1210 of each ramp assembly 1200 defines a hook having a substantially “u” shaped channel such that the opening thereof faces upwardly towards the plate portion 1212. The rib member 1218 of each ramp panel 1210 of each ramp assembly 1200 extends generally perpendicularly from plate portion 1212. A lip 1219 is disposed at the free end of each rib member 1218 and extends in substantially perpendicular orientation therefrom towards the second connector 1216.

[0122] Depending upon the orientation of the ramp assembly 1200 and / or the side of platform assembly 1100 to which the ramp assembly 1200 is to be connected, the connector 1214, 1216 presented for attachment to platform assembly 1100 may differ. More specifically, as shown in FIGS. 49-51, first connector 1214 of the first ramp assembly 1200 is presented for attachment to the connector panel 1130 on one side of platform assembly 1100 while second connector 1216 of the second ramp assembly 1200 is presented for attachment to the connector panel 1130 on the opposite side of platform assembly 1100.

[0123] Referring to FIGS. 55 and 56, first connector 1214 and connector 1140 are oriented complementary to one another. That is, first connector 1214, as noted above, defines a hook having a substantially “n” shaped channel and connector 1140, as also noted above, defines a hook having a substantially “u” shaped channel. As such, first connector 1214 and connector 1140 may engage one another similarly as detailed above with respect to the connection of connectors 214 and 216 (FIGS. 13-15) to thereby engage the first connector 1214 of the first ramp assembly 1200 to the connector panel 1130 on one side of platform assembly 1100. In aspects, this engagement may be secured with a suitable fastener, e.g., a set screw “SS” or a rod “R,” extending at least partially through the boss 1220 formed by the engagement of first connector 1214 and connector 1140.

[0124] Turning to FIGS. 57A-60, second connector 1216 and connector 1140, on the other hand, are not complementary to one another and, thus, cannot be readily attached in the same manner as first connector 1214 (FIGS. 55 and 56) and connector 1140. That is, second connector 1216, as noted above, defines a hook having a substantially “u” shaped channel and connector 1140, as likewise noted above, also defines a hook having a substantially “u” shaped channel. Thus, in order to enable engagement of second connector 1216 and connector 1140, a ramp adapter 1190 is utilized.

[0125] Ramp adapter 1190 includes a plate portion 1192 and a web 1194 extending from plate portion 1192. Plate portion 1192 and web 1194 cooperate to define first and second adapter connectors 1193a, 1193b (also referred to herein as the connector panel connector and ramp panel connector, respectively)—on opposite sides of web 1194, wherein each adapter connector 1193a, 1193b defines a hook having a substantially “n” shaped channel with the opening thereof facing away from plate portion 1192. Web 1194 includes a first portion 1195a that extends from plate portion 1192 in substantially perpendicular orientation relative to plate portion 1192, a second portion 1195b that extends in substantially parallel orientation relative to first portion 1195a, and a third portion 1195c that connects first and second portions 1195a, 1195b and defines a curved or angled configuration. Further, web 1194 includes a lip 1196 at the free end of second portion 1195b. Lip 1196 may be formed by a substantially “s” (or backwards “s”) shaped bend towards the end of second portion 1195b of web 1194 or in any other suitable manner, e.g., via any other suitable curve, bend, or angle, formed in second portion 1195b of web 1194.

[0126] As detailed below, during assembly, first adapter connector 1193a of ramp adapter 1190 is configured to engage second connector 1216 of ramp panel 1210 and lip 1196 of ramp adapter 1190 is configured to engage lip 1219 of rib member 1218 of ramp panel 1210 to thereby engage ramp adapter 1190 with second ramp assembly 1200. Further, second adapter connector 1193b of ramp adapter 1190 is configured to engage connector 1140 of connector panel 1130 of platform assembly 1100, to thereby engage second ramp assembly 1200 with platform assembly 1100 via ramp adapter 1190.

[0127] Referring to FIGS. 57A-57D, as noted above, first adapter connector 1193a of ramp adapter 1190 is configured to engage second connector 1216 of ramp panel 1210 and lip 1196 of ramp adapter 1190 is configured to engage lip 1219 of rib member 1218 of ramp panel 1210 to thereby engage ramp adapter 1190 with second ramp assembly 1200. More specifically, first adapter connector 1193a, defining a hook having a substantially “n” shaped channel, is configured to engage second connector 1216, defining a complementary hook having a substantially “u” shaped channel, by: initially, as shown in FIG. 57A, inserting first adapter connector 1193 into overlapping relation with second connector 1216; next, as shown in FIG. 57B, rotating ramp adapter 1190 clockwise relative to second connector 1216 (from the orientation shown in FIGS. 57A-57D); and subsequently, as shown in FIG. 57C, sliding ramp adapter 1190 towards second connector 1216 to define a boss 1198 between the overlapping and engaged connectors 1193a, 1216 and such that first adapter connector 1193a is received at least partially beneath an overhang 1213 of plate portion 1212 of ramp panel 1210 to define a tongue and groove engagement therewith (such a tongue and groove engagement is also established with respect to the similar connector engagements detailed hereinabove). In order to secure this engagement, a suitable fastener, e.g., a set screw “SS” or a rod “R,” may be inserted at least partially through the boss 1222. In addition, in order to further secure this engagement, e.g., as a safety engagement, lip 1196 of ramp adapter 1190 is manipulated to sit on lip 1219 of rib member 1218 of ramp panel 1210, thereby engaging lips 1196, 1219 with one another and inhibiting disengagement between ramp adapter 1190 and second ramp assembly 1200.

[0128] Turning to FIGS. 58-60, once ramp adapter 1190 is engaged with second ramp assembly 1200, second adapter connector 1193b is presented for attachment to platform assembly 1100. More specifically, second adapter connector 1193b and connector 1140 of connector panel 1130 of platform assembly 1100 are oriented complementary to one another. That is, second adapter connector 1193b, as noted above, defines a hook having a substantially “n” shaped channel and connector 1140, as also noted above, defines a hook having a substantially “u” shaped channel. As such, second adapter connector 1193b and connector 1140 may engage one another similarly as detailed above with respect to the connection of connectors 214 and 216 (FIGS. 13-15) and / or with respect to the connection of first adapter connector 1193a and connector 1216 (FIGS. 57A-57D) to thereby engage the second ramp assembly 1200 to the connector panel 1130 of platform assembly 1100 via ramp adapter 1190. In aspects, this engagement may be secured with a suitable fastener, e.g., a rod “R” (as shown in FIG. 60) or a set screw, extending at least partially through a second boss 1198 formed by the engagement of second adapter connector 1193b and connector 1140.

[0129] With reference to FIGS. 61 and 62, corner bracket 1150 is detailed. Corner bracket 1150 defines a generally rectangular frame 1152 defining an interior passage 1153 and including opposing inner and outer corners 1154a, 1154b and diagonally opposing side shoulders 1155a, 1155b. Side shoulders 1155a, 1155b are indented into interior passage 1153 of body 1152.

[0130] Inner and outer corners 1154a, 1154b may define increased thicknesses compared to the remainder of frame 1152 to provide increased structural support. One or more threaded apertures 1156 is defined through each of inner and outer corners 1154a, 1154b. In aspects, plural threaded apertures 1156 are spaced along the lengths of inner and outer corners 1154a, 1154b. Threaded apertures 1156 are configured to receive, in threaded engagement, fasteners, e.g., screws “S,” extending therethrough and into interior passage 1153 of body 1152.

[0131] Side shoulders 1155a, 1155b, as noted above, are indented into interior passage 1153 of body 1152. More specifically, a first indented portion of frame 1152 defines first and second walls 1157a, 1157b that meet to form and define side shoulder 1155a, and a second, opposed indented portion of frame 1152 defines first and second walls 1158a, 1158b that meet to define side shoulder 1155b. First wall 1157a of side shoulder 1155a extends from outer frame 1152 at a non-perpendicular angle, while second walls 1157b of side shoulder 1155a extends from an outer wall of frame 1152 at a perpendicular angle. Thus, inner surfaces of first and second walls 1157a, 1157b of side shoulder 1155a are non-perpendicular relative to one another (and also non-parallel relative to one another), e.g., non-perpendicular, in aspects, by at least about 5 degrees; in other aspects, by at least about 7.5 degrees; or, in still other aspects, by at least about 10 degrees. First and second walls 1158a, 1158b of side shoulder 1155b are configured in the same manner. Thus, as a result of the above-detailed configuration and the diagonally-opposed positioning of side shoulders 1155a, 1155b relative to one another, the inner surfaces of first walls 1157a, 1158a are non-perpendicular relative to one another (and also non-parallel relative to one another), while the inner surfaces of second walls 1157b, 1158b are substantially perpendicular relative to one another. More specifically, first walls 1157a, 1158a define an acute angle therebetween of, in aspects, equal to or less than about 80 degrees; in other aspects, equal to or less than about 75 degrees; or, in still other aspects, equal to or less than about 70 degrees. In other configurations, and with momentary reference to FIG. 63, the inner surfaces of first and second walls 1157a, 1157b of side shoulder 1155a may be substantially perpendicular relative to one another and / or inner surfaces of first and second walls 1158a, 1158b of side shoulder 1155b may be substantially perpendicular relative to one another. In such aspects, first wall 1157a of side shoulder 1155a may extend from outer frame 1152 at a perpendicular angle, and / or first wall 1158a of side shoulder 1155b may extend from an outer wall of frame 1152 at a perpendicular angle.

[0132] Referring again to FIGS. 61 and 62, corner bracket 1150 further includes an exterior flange 1160 extending outwardly from frame 1152 adjacent to each side shoulder 1155a, 1155b. Flanges 1160 are substantially perpendicular relative to one another and each defines one or more apertures 1162 spaced along the lengths of the flange 1160. In aspects, first and second apertures 1162 are defined through each flange 1160 and are positioned to align with upper and lower c-shaped channels 1138, 1139 of corresponding connector panels 1130 (see FIG. 54) to enable fasteners, e.g., screws “S,” to be threaded through apertures 1162 and into engagement with channels 1138, 1139 of connector panels 1130 to thereby secure corner bracket 1150 relative to the connector panels 1130 that meet at that corner.

[0133] Continuing with reference to FIGS. 61 and 62, corner bracket 1150 is configured to receive an upright support 1510 of a leg 1500 as well as a corner post 1301 of a hand rail assembly. Upright support 1510 of leg 1500, more specifically, defines a generally square cross-sectional configuration and is configured for positioning within interior passage 1153 of frame 1152 of corner bracket 1150 with adjacent side walls of upright support 1510 adjacent to or in contact with second walls 1157b, 1158b of side shoulders 1155a, 1155b. Upright support 1510 of leg 1500 is telescopically slidable through interior passage 1153 of frame 1152. Once the desired position of upright support 1510 of leg 1500 is achieved, e.g., corresponding to a desired height of platform assembly 1100, fasteners, e.g., screws “S,” engaged through the threaded apertures 1156 of outer corner 1154b of frame 1152 of corner bracket 1150 are tightened against the corresponding corner of upright support 1510 to thereby urge the adjacent side walls of upright support 1510 into contact with second walls 1157b, 1158b of side shoulders 1155a, 1155b to retain upright support 1510 in fixed position within corner bracket 1150 via interference-fit engagement.

[0134] Corner post 1301 of the hand rail assembly includes first and second walls 1302, 1304 disposed in substantially perpendicular orientation relative to one another to define an L-shaped configuration. Corner post 1301 is configured for positioning within interior passage 1153 of body 1152 with the interior corner defined by first and second walls 1302, 1304 facing inwardly towards upright support 1510 of leg 1500, with the exterior corner defined by first and second walls 1302, 1304 facing inner corner 1154a, and with the free ends of first and second walls 1302, 1304 disposed adjacent or in contact with first walls 1157a, 1158a of side shoulders 1155a, 1155b. With corner post 1301 in position, fasteners, e.g., screws “S,” engaged through the threaded apertures 1156 of inner corner 1154a of frame 1152 of corner bracket 1150 are tightened against the exterior corner of corner post 1301 to thereby urge the free ends of first and second walls 1302, 1304 of corner post 1301 into contact with first walls 1157a, 1158a of side shoulders 1155a, 1155b to retain corner post 1301 in fixed position within corner bracket 1150 via interference-fit engagement.

[0135] The angled, e.g., non-perpendicular, first walls 1157a, 1158a facilitate engagement of corner post 1301 via the fasteners by enabling sliding of the free ends of walls 1302, 1304 of corner post 1301 along first walls 1157a, 1158a until the interference-fit engagement is achieved. The substantially perpendicular second walls 1157b, 1158b facilitate engagement of upright support 1510 by enabling substantially flush abutment of the adjacent side walls of upright support 1510 with second walls 1157b, 1158b.

[0136] From the foregoing and with reference to the various drawing figures, those skilled in the art will appreciate that certain modifications can also be made to the present disclosure without departing from the scope of the same. While several embodiments of the disclosure have been shown in the drawings, it is not intended that the disclosure be limited thereto, as it is intended that the disclosure be as broad in scope as the art will allow and that the specification be read likewise. Therefore, the above description should not be construed as limiting, but merely as exemplifications of particular embodiments. Those skilled in the art will envision other modifications within the scope and spirit of the claims appended hereto.
