Dynamic morphing support mechanism and deployable and stowable structure comprising the same

Abstract

A deformable support mechanism for a load bearing support structure includes a first chain assembly, a second chain assembly, and a work surface subassembly coupled to the first chain assembly. Links in the first chain assembly have inwardly facing structural features, and links in the second chain assembly have inwardly facing structural features. The inwardly facing structural features are configured to releasably couple together in response to coordinated movement of the first and second chain assemblies along a predefined deployment path, and are configured to separate and decouple from one another in response to coordinated movement of the first and second chain assemblies along a predefined stowage path. The work surface subassembly cooperates to form a deployable work surface, and the inwardly facing structural features interlock when deployed to self-support, such that the deployable work surface is load bearing.

Description

Technical Field

[0001] The embodiments of the subject matter described herein generally relate to deployable and retractable support structures employing dynamically deformable support mechanisms. More specifically, embodiments of this subject matter relate to retractable load-bearing support structures suitable for transportation applications (aircraft, ships, automobiles, trains, spacecraft), such as tables, armrests, headrests, doors, or walls. Background Technology

[0002] Deployable, retractable, and collapsible components, structures, and support surfaces are commonly used in applications with limited physical space. For example, vehicles such as aircraft can utilize tables, seat trays, armrests, cup holders, display devices, footstools, or doors, which can be deployed, extended, or otherwise removed from storage as needed. These and other types of rigid structures or support surfaces may be inconvenient or bulky to retract when not in use. Furthermore, traditional mechanisms that facilitate the deployment and retraction of physical components can be overly complex, noisy, and / or difficult to install and maintain.

[0003] Therefore, it is desirable to have a support mechanism or sub-assembly that can be used with deployable and retractable structures, wherein the structure and its support mechanism can dynamically deform between a rigid load-bearing state and a compact, retractable, folded-back state. Furthermore, other desirable features and characteristics will become apparent, in conjunction with the accompanying drawings and the foregoing technical and background information, based on the following detailed description and the appended claims. Summary of the Invention

[0074] This document discloses dynamically deformable (shape-changing) support mechanisms and related physical structures that can be deployed into a stable and load-bearing state and retracted into a compact and collapsible state. According to some embodiments, the disclosed mechanisms and support structures can be used on vehicles such as aircraft. For example, the accompanying drawings depict an exemplary embodiment suitably configured as a collapsible table on an aircraft. However, it should be understood that embodiments of the disclosed subject matter can be used in other transportation applications, including but not limited to: trains; helicopters; automobiles; boats; monorails; amusement park rides; transportation systems; ski lifts; or the like. Furthermore, embodiments of the disclosed subject matter can also be used in non-transportation applications, including but not limited to: residential applications; commercial applications; office space applications; tools; manufacturing facilities; entertainment equipment; and so on. This disclosure contemplates these and other applications, use cases, and platforms. For example, in addition to load-bearing surfaces, the support mechanisms and systems described below can be used in vertical or curved arrangements, such as for applications for mounting display monitors.

[0075] Refer to the attached diagram. Figure 1 It is a perspective front view of the load-bearing support structure 100 in its retracted and stowed state, and Figure 2This is a perspective front view of the load-bearing support structure 100 in its extended and unfolded state. The illustrated embodiment of the support structure 100 is implemented as a retractable table, suitable for aircraft cabin applications. This disclosure also contemplates other platforms, use cases, and configurations of the support structure 100, and the implementation of the exemplary table shown in the figures is not intended to be limiting, exhaustive, or restrictive in any way.

[0076] The support structure 100 includes a deformable support mechanism 102, which can be in a retracted and stowed state (in Figure 1 (depicted in the middle) and extended and unfolded states (in Figure 2 The support mechanism 102 (or most of it) moves between the two positions (as depicted in the image). When fully retracted and positioned in the stowed state, the entire support mechanism 102 resides within a suitably shaped, sized, and configured storage unit 104, which has internal storage space defined therein. Figure 1 As shown, when the support mechanism 102 is in the retracted state, the front section 106 or surface of the support mechanism 102 may be exposed or protruded from the storage unit 104. The exposed or protruding front section 106 can be used to facilitate the removal and deployment of the support mechanism 102 from the storage unit 104 as needed.

[0077] The illustrated embodiment utilizes a support mechanism 102 designed and configured to accommodate (or adapt) movement along a predefined unfolding path to transition it from a retracted state to an unfolded state. In this respect, the support mechanism 102 can be unfolded (extending from the opening 107 defined in the storage unit 104) to create a load-bearing, unfoldable working surface 108. For this particular example, the unfolded portion of the working surface 108 is flat and load-bearing on its two main surfaces (e.g., the top and bottom surfaces). The support mechanism 102 is also designed and configured to accommodate movement along a predefined retracting path to transition it from an unfolded state to a retracted state. Although not always necessary, the retracting path of the support mechanism 102 corresponds to the unfolding path of the support mechanism 102, wherein the unfolding and retracting paths are opposite paths.

[0078] According to some embodiments, the internal space of the storage unit 104 is shaped and sized to accommodate folded storage of at least a portion of the support mechanism 102. In this case, Figure 3 This is a perspective front view of an exemplary embodiment of the support mechanism 102, suitable for use with the support structure 100. Figure 3 The image shows the support mechanism 102 in its retracted and stowed state, wherein at least a portion of the support mechanism 102 is folded to save storage unit 104. Figure 3The space within (not shown in the image). As described in more detail below, various embodiments of the support mechanism 102 are implemented with a plurality of hinged upper components 114 and a plurality of hinged lower components 116, which cooperate and interlock with each other when deployed to form a self-supporting load-bearing component. However, when retracted for storage, the hinged upper components 114 and hinged lower components 116 are decoupled from each other and become independently movable relative to each other (see [link to documentation]). Figure 3 The illustration depicts an exemplary folded or wrapped arrangement of the support mechanism 102. Folded storage of the support mechanism 102 is desirable for applications with limited or restricted storage space. The illustrated example of storage unit 104 is suitable for applications such as consoles or short partitions on vehicles like aircraft, furniture, or the like. Other shapes, sizes, shape factors, and configurations may also be used.

[0079] First Embodiment

[0080] Figures 4-43 Various structures and features associated with embodiments of a load-bearing support structure are described, which employs at least one deformable support mechanism having structural features similar to hooks or fingers, wherein the hooks interlock with each other when the support structure is deployed. Figure 4 This is a perspective top rear view applicable to the lower component 202 used with the disclosed embodiments, and Figures 5-15 Various components and sub-components of the lower assembly 202 are depicted. As explained in more detail below, embodiments of the load-bearing support structure utilize multiple of these lower assemblies 202 that are connected in series and hinged together to form part of a deformable support mechanism.

[0081] exist Figure 4 In the diagram, directional arrow 204 points forward, which corresponds to the unfolding direction of the lower component 202. The opposite direction of directional arrow 204 corresponds to the rearward or retracted direction of the lower component 202. Therefore, this description refers to the leading edge section 206 of the lower component (typically spanning the width of the lower component 202) and the trailing edge section 208 of the lower component (also typically spanning the width of the lower component 202), where "front" and "rear" correspond to the forward / unfolding direction indicated by directional arrow 204. The depicted embodiment of the lower component 202 includes, but is not limited to: link component 210; spring assembly 212; lower support slat 214; and end cap 216. These major components of the lower component 202 are coupled together using appropriate hardware, sub-components, and / or materials.

[0082] For this particular embodiment, the link components 210 are identical, and a pair of link components 210 are arranged to define a chain link. For example, two link components 210 cooperate to form a lower right chain link 217, and two link components 210 cooperate to form a lower left chain link 218 (where "left" and "right" refer to the corresponding sides when the lower assembly 202 is viewed from the front, e.g., directly at the leading edge segment 206). Although Figure 4 An arrangement including two lower chain links is depicted, but alternative embodiments of the lower component may include only one lower chain link or two or more lower chain links, which is suitable for specific use cases, intended applications of load-bearing support structures, shapes and sizes of deployable support surfaces, and various strength, durability, and load-bearing capacity requirements.

[0083] As shown and described in more detail below, link component 210 is suitably configured and arranged to form a front hinge structure and a rear hinge structure for the lower assembly. The front hinge structure is located at or near the front edge segment 206, and the rear hinge structure is located at or near the rear edge segment 208. The front hinge structure of the lower assembly 202 is configured to provide a front hinge rotation axis 222, and the rear hinge structure of the lower assembly 202 is configured to provide a rear hinge rotation axis 224. When multiple lower assemblies 202 are hinged together in series, the hinge structures allow adjacent lower assemblies 202 to rotate relative to each other on the front and rear hinge rotation axes 222, 224. This hinge arrangement facilitates compact (folded or bent) storage of the lower assemblies 202 if desired.

[0084] Figures 5-8 Different views of a link component 210 (for lower component 202) are depicted. Figure 5 This is the right front view. Figure 6 This is the left front view. Figure 7 This is the left-side view. Figure 8 This is a bottom view. The link component 210 can be made of any suitable material with the desired strength and toughness, such as aluminum, nylon, composite materials, plastics, etc.

[0085] This figure illustrates the structural features of the lower assembly front hinge structure 226 and the lower assembly rear hinge structure 228 forming the lower assembly 202. The front and rear hinge structures 226 and 228 occupy approximately half the minimum width of the link member 210. This configuration accommodates the link / hinge of multiple link members 210 connected in series. The front hinge structure 226 includes a hole 230 formed therein to receive a hinge pin, rod, bolt, or any suitably configured fastener or coupling element. Similarly, the rear hinge structure 228 includes a hole 232 formed therein to receive another hinge pin, rod, bolt, fastener, coupling element, etc. A line passing through the center of the hole 230 corresponds to the front hinge rotation axis 222, and a line passing through the center of the hole 232 corresponds to the rear hinge rotation axis 224 (see figure). Figure 7 ).

[0086] The base of the link component 210 includes a groove 234 formed therein. The groove 234 is shaped, sized, and configured to receive a portion of the lower support strip 214 (see...). Figure 15 The base of link component 210 may also include any number of threaded holes or inserts 236 to receive threaded fasteners for coupling the lower support strip 214 to link component 210. In some embodiments, link component 210 includes a plurality of through holes 238 (which may be countersunk on one or both sides) to receive screws, bolts, or other fasteners for coupling end cap 216 to link component 210 (see [link to documentation]). Figures 12-15 ).like Figure 4 As shown, the two outermost link components 210 have end caps 216 to which are attached, while the other link components 210 do not have end caps 216. In the illustrated implementation, the end caps 216 are decorative end caps that, when unfolded, cooperate to provide exposed sidewall surfaces for the lower assembly 202 (see Figure 1). Figure 2 and Figures 33-35 For this purpose, the end cap 216 can be made of wood, wood-like material, plastic, metal or any desired material, with or without additional decorative treatments, coatings or textures.

[0087] Link component 210 includes a structural interlocking feature 240 for lower component 202. As described below, the structural interlocking feature 240 is shaped, sized, arranged, and configured to cooperate with a corresponding structural interlocking feature of a compatible upper component. When deployed in an assembled load-bearing support mechanism, the structural interlocking feature 240 is oriented as an inward-facing structural feature (opposite to certain outward-facing structural features of link component 210, such as slot 234). According to the illustrated embodiment, the structural interlocking feature 240 includes, but is not limited to, a hook / finger structure 242 terminating at a protrusion 244 that substantially corresponds to... Figure 4The direction arrow 204 extends in the forward / spreading direction indicated by the arrow. The upper surface of the hook / finger structure 242 is convex, having a side profile shape that curves upward from the base of the link member 210, reaches its apex at the maximum height point of the link member 210, and curves downward until it terminates at the tip of the protrusion 244 (see [link]). Figure 7 The protrusion 244 forms an overhanging shelf that defines a bag space 246 below the shelf and above the front hinge structure 226. An important aspect of the link member 210 is that the hook / finger structure 242 is radially centered at the front pivot point of the link member 210 (hinge rotation axis 222). Furthermore, the hook / finger structure 242 narrows slightly along its leading edge to facilitate proper alignment and engagement with the corresponding link member of the upper assembly, as described below.

[0088] Figures 9-11 These are different views of an exemplary embodiment of the spring assembly 212 used with the lower assembly 202. Figures 13-15 A spring assembly 212 is shown mounted together with the corresponding link component 210. As described in more detail below, when the current assembly 202 is mounted for use with a load-bearing support structure, the spring assembly 212 is shaped, sized, configured, and positioned to engage at least one guide rail. In some implementations, the spring assembly 212 is made of a robust and resilient material, such as plastic, nylon, DELRIN, aluminum, etc.

[0089] The depicted embodiment of spring assembly 212 includes, but is not limited to, sidewall 250 and leaf spring 252 coupled to or integrated with sidewall 250. Sidewall 250 is shaped and configured for coupling abutting against adjacent link member 210. More specifically, the outer surface 254 of sidewall 250 faces link member 210 during installation, and the inner surface 256 of sidewall 250 faces another spring assembly 212 during installation (see...). Figures 13-15 The sidewall 250 includes two mounting holes 258 formed therein, corresponding to and aligned with holes 230, 232 formed in and with the hinge structures 226, 228 of the link member 210. The sidewall 250 has a first recessed section 260 (inner side) and a second recessed section 262 (outer side). The recessed sections 260, 262 are shaped, sized, configured, and arranged to accommodate a link / hinge of multiple spring assemblies 212 connected in series.

[0090] According to the illustrated embodiment, the leaf spring 252 is coupled to or integrated with the upper section of the sidewall 250. The leaf spring 252 can be implemented as a thin plate-like structure with a curved side profile shape (see...). Figure 10For this particular example, the lower surface of the leaf spring 252 is convex, having a side profile shape that curves downward from the engagement of the sidewall 250, reaches a minimum height point at the point between the holes 258 (which is closer to the second recess 262 than the first recess 260), and then curves slightly upward until it terminates at its distal edge. The shape, size, and deflection characteristics of the leaf spring 252 are designed to allow the leaf spring 252 to bend upon contact with the guide rail, thereby applying the amount of force required to hold the link member 210 on the guide rail.

[0091] Figures 12-15 It is a perspective view depicting the assembly steps associated with the manufacture of the lower component 202. Figure 12 The diagram shows a first link component 210-1 after the internally threaded insert 266 is installed into the hole 232, and a second link component 210-2 after the threaded fastener 268 is installed into the hole 238. Although in Figures 12-15 It is not described in the text, but the decorative end cap 216 is coupled to the side of the second link component 210-2 via a threaded fastener 268. Figure 13 The desired alignment and orientation of the first spring assembly 212-1 and the second spring assembly 212-2 are shown. Note that the leaf springs of the two spring assemblies 212-1 and 212-2 are oriented in opposite directions. Also note that the two spring assemblies 212-1 and 212-2 are arranged on the respective inner sides of the link members 210-1 and 210-2 such that the two leaf springs are opposite to each other. Figure 14 The desired alignment and positioning of the hollow roller 270 is shown (the main longitudinal axis of the hollow roller 270 is aligned with the front hinge rotation axis 222 defined by the hole 230). Bolts 272 or other types of fasteners are shaped and sized for insertion through: the hole 230 of the second link component 210-2; the hole 258 of the second spring assembly 212-2; the hollow roller 270; the hole 258 of the first spring assembly 212-1; and the hole 230 of the first link component 210-1. Figure 15 The assembled lower chain links 274 are depicted, including but not limited to various components surrounded by dashed lines. Figure 15 The end section of the lower support strip 214 is also shown, which is shaped and sized to fit into the slot 234 of the link components 210-1, 210-2. Threaded fasteners 276 can be used to attach the lower support strip 214 to the two link components 210-1, 210-2 (see again). Figure 4 ).

[0092] although Figure 15Not depicted, bolt 272 is used for tandem coupling of another lower chain link 274. In this respect, when the two lower chain links 274 are hinged together, bolt 272 passes through the front hinge structure 226 of the rear lower chain link 274 and through the rear hinge structure 228 of the front lower chain link 274. The threaded insert 266 of the front lower chain link 274 receives the threaded end of bolt 272, and the bolt is tightened to secure the two lower chain links 274 together while allowing them to rotate about the corresponding hinge axis of rotation. Bolt 272 can also be used to couple the final lower chain link 274 to the leading edge link (see reference below). Figure 32 (As described).

[0093] Figures 16-24 Exemplary embodiments relating to the upper component 302 used in conjunction with the disclosed embodiments. Figure 16 It is the perspective top-down rear view of the upper component 302, and Figures 17-24 Various components and sub-components of the upper assembly 302 are depicted. As explained in more detail below, embodiments of the load-bearing support structure utilize multiple such upper assemblies 302, which are hinged together in series, to form part of a deformable support mechanism. Some structural, feature, and functional characteristics of the upper assembly 302 are similar, identical, or equivalent to those described above for the lower assembly 202. For simplicity and brevity, in the context of the upper assembly 302, such similar, identical, or equivalent aspects will not be described in redundant detail here.

[0094] exist Figure 16 In the diagram, directional arrow 304 points forward, which corresponds to the unfolding direction of the upper component 302. The opposite direction of directional arrow 304 corresponds to the rearward or retracted direction of the upper component 302. Therefore, this description relates to the leading edge section 306 and the trailing edge section 308 of the upper component. The depicted embodiment of the upper component 302 includes, but is not limited to: link member 310; spring assembly 312 (in... Figure 16 The upper component 302 is essentially hidden in view; and the outer surface 314 defines a portion of the deployable working surface. These main components of the upper component 302 are coupled together using appropriate hardware, sub-components, and / or materials.

[0095] In this particular embodiment, the link components 310 are identical, and a pair of link components 310 are arranged to define a chain link. Although Figure 16 An arrangement including two upper chain links (on the left and right sides of the upper component 302) is depicted, but alternative embodiments of the upper component may include only one upper chain link or two or more upper chain links, which is suitable for specific use cases, intended applications of load-bearing support structures, shapes and sizes of deployable support surfaces, and various strength, durability and load-bearing capacity requirements.

[0096] As shown and described in more detail below, link component 310 is suitably configured and arranged to form a front hinge structure and a rear hinge structure for the upper assembly. The front hinge structure is located at or near the front edge segment 306, and the rear hinge structure is located at or near the rear edge segment 308. The front hinge structure of the upper assembly 302 is configured to provide a front hinge rotation axis 322, and the rear hinge structure of the upper assembly 302 is configured to provide a rear hinge rotation axis 324. When multiple upper assemblies 302 are hinged together in series, the hinge structures allow adjacent upper assemblies 302 to rotate relative to each other on the front and rear hinge rotation axes 322, 324. This hinge arrangement facilitates compact (folded or bent) storage of the upper assemblies 302 if desired.

[0097] Figures 17-20 Different views of a link component 310 (for upper component 302) are depicted. Figure 17 This is the right front view. Figure 18 This is the left front view. Figure 19 This is the left-side view. Figure 20 This is a top view. The figure illustrates the structural features of the upper component front hinge structure 326 and the upper component rear hinge structure 328 forming the upper component 302. The front and rear hinge structures 326 and 328 occupy approximately half the width of the link member 310, accommodating the links / hinges of multiple link members 310 connected in series. The front hinge structure 326 includes a hole 330 formed therein to accommodate a hinge pin, rod, bolt, or any suitably configured fastener or coupling element. Similarly, the rear hinge structure 328 includes a hole 332 formed therein to accommodate another hinge pin, rod, bolt, fastener, coupling element, etc. A line passing through the center of the hole 330 corresponds to the front hinge rotation axis 322, and a line passing through the center of the hole 332 corresponds to the rear hinge rotation axis 324 (see figure). Figure 19 ).

[0098] The top section of link member 310 includes a groove 334 formed therein (as shown, which may be chamfered). The groove 334 is shaped, sized, and configured to receive a portion of a working surface sub-member 336 that includes, carries, or defines an outer surface 314 (see figure). Figure 23 and Figure 24 The top section of the link component 310 may also include at least one threaded hole or insert 337 (which may be a countersunk hole) to receive a threaded fastener for securing the working surface sub-component 336 to the link component 310. Figure 16As shown, the two outermost link components 310 receive fasteners used to hold the working surface sub-component 336 in place after it has been installed into the slot 334. Although not used in the illustrated embodiment, the link components 310 may be suitably configured to allow them to receive decorative end caps (as described above with reference to the end cap 216 for the lower component 202).

[0099] Link member 310 includes a structural interlocking feature 340 for upper assembly 302. Note that the structural interlocking feature 340 is shaped, sized, arranged, and configured to cooperate with a corresponding structural interlocking feature 240 of link member 210 of lower assembly 202. When deployed in the assembled load-bearing support mechanism, the structural interlocking feature 340 is oriented as an inward-facing structural feature (opposite to certain outward-facing structural features of link member 310, such as slot 334). According to the illustrated embodiment, the structural interlocking feature 340 includes, but is not limited to, a hook / finger structure 342 terminating at a protrusion 344 extending in a direction generally corresponding to the rearward / retracted direction. The hook / finger structure 342 exhibits a side profile shape that begins at or near the front hinge structure 326 with a rearwardly sloping, straight, angled leading edge, bends rearward and downward until it reaches the lowest point of link member 310, and bends rearward and upward until it terminates at the tip of protrusion 344 (see...). Figure 19 The protrusion 344 forms an overhanging shelf that defines a bag space 346 above the shelf and below the top section of the link member 310.

[0100] Figures 21-24 It is a perspective view depicting the assembly steps associated with the manufacture of the upper component 302. Figure 21 The diagram shows the first link assembly 310-1 after the internal thread insert 366 is installed into the hole 332, the second link assembly 310-2 before assembly, and the spring assembly 212 (as shown in the reference). Figures 9-11 (As described). Figure 22 The desired alignment and positioning of the hollow roller 370 is shown (the main longitudinal axis of the hollow roller 370 is aligned with the front hinge rotation axis 322 defined by the hole 330). Bolts 372 or other types of fasteners are shaped and sized for insertion through: the hole 330 of the second link component 310-2; the hole 258 of a spring assembly 212; the hollow roller 370; the hole 258 of another spring assembly 212; and the hole 330 of the first link component 310-1. Figures 22-24 An assembled upper chain link 374 is depicted, which includes two link components 310-1 and 310-2 coupled together.

[0101] Figure 23An end section of the working surface sub-component 336 is shown, which is shaped and sized to fit within a slot 334 of link components 310-1, 310-2. According to some embodiments, the working surface sub-component 336 includes a slat 376 having an inner side 378 and an outer side 380 opposite to the inner side 378. The inner side 378 has a slat coupling feature 382 configured to engage and couple with certain outward-facing structural features (e.g., slot 334) of the upper chain link 374. In the illustrated embodiment, the slat coupling feature 382 includes a protruding section of the slat 376 having a side profile shape corresponding to the side profile shape of the slot 334. This allows the slat 376 to be inserted into the slot 334 of the link component 310 (see [link name missing]). Figure 24 The outer side 380 of the slat 376 defines a portion of the deployable working surface of the load-bearing support structure, such that the outer sides 380 of the multiple deployed slats 376 cooperate to form the deployed working surface. According to some embodiments, the slat 376 includes a decorative material layer defining the outer side 380 (e.g., a painted or treated layer of wood veneer, patterned laminate, plastic, metal, or vinyl). In other embodiments, the slat 376 may be made of a single sheet material, such as aluminum, with a decorative treatment or coating on its outer side 380. Threaded fasteners 383 may be used to attach or secure the working surface sub-component 336 to multiple link components 310 (see...). Figure 16 and Figure 24 ).

[0102] although Figure 24 Not depicted, however, bolt 372 is used for tandem coupling of another upper chain link 374. In this respect, when the two upper chain links 374 are hinged together, bolt 372 passes through the front hinge structure 326 of the rear upper chain link 374 and through the rear hinge structure 328 of the front upper chain link 374. The threaded insert 366 of the front upper chain link 374 receives the threaded end of bolt 372, which is tightened to secure the two upper chain links 374 together while allowing them to rotate about their respective hinge axes. Bolt 372 can also be used to couple the final upper chain link 374 to the leading edge link (see reference below). Figure 32 (As described).

[0103] Figures 25-31 Exemplary embodiments relating to a leading edge component 402 suitable for use with the disclosed embodiments are described. Figure 25 It is a perspective top rear view of the leading edge component 402, and Figures 26-30 Various parts and sub-components of the leading edge assembly 402 are depicted. Figure 31This is a perspective top front view of the chain assembly, showing the manner in which the upper link component, lower link component, and leading edge link component are coupled together according to an exemplary embodiment. Some structural features, characteristics, and functional properties of the leading edge assembly 402 are similar, identical, or equivalent to those described above for the lower component 202 and / or the upper component 302. For simplicity and brevity, in the context of the leading edge assembly 402, such similar, identical, or equivalent aspects may not be described in redundant detail herein.

[0104] exist Figure 25 In the diagram, directional arrow 404 points forward, which corresponds to the unfolding direction of the leading edge assembly 402. The opposite direction of directional arrow 404 corresponds to the rearward or retracted direction of the leading edge assembly 402. The depicted embodiment of the leading edge assembly 402 includes, but is not limited to: a leading edge link member 410; a mounting bracket assembly 412; and at least one decorative member 414, which includes or is made of decorative material. These main components of the leading edge assembly 402 are coupled together using appropriate hardware, sub-components, and / or materials.

[0105] For this particular embodiment, the link components 410 are identical, and a pair of link components 410 are arranged to define a leading edge link 415 (see...). Figure 31 ).although Figure 25 An arrangement including two leading edge links (on the left and right sides of leading edge assembly 402) is depicted, but alternative embodiments of the leading edge assembly may include only one leading edge link or more than two leading edge links, which is suitable for specific use cases, intended applications of load-bearing support structures, shapes and sizes of deployable support surfaces, and various strength, durability and load-bearing capacity requirements.

[0106] See below for reference. Figure 31 As shown and described in more detail, link member 410 is suitably configured and arranged to form a top hinge structure and a bottom hinge structure of leading edge assembly 402. The top hinge structure is arranged and configured for compatibility with link member 310 of upper assembly 302, and the bottom hinge structure is arranged and configured for compatibility with link member 210 of lower assembly 202. These hinge structures facilitate rotation of the corresponding upper and lower assemblies 302, 202 about a respective hinge rotation axis defined by the hinge structure.

[0107] Figures 26-28 Different views of a link component 410 (for leading edge assembly 402) are depicted. Figure 26 This is the right rear view. Figure 27 This is the right-side view. Figure 28This is a left front view of two side-by-side link components 410. The figure illustrates the structural features of the top hinge structure 416 and the bottom hinge structure 418 forming the leading edge assembly 402. The top and bottom hinge structures 416, 418 occupy approximately half the width of the link component 410, accommodating the link / hinging of the lower assembly link component 210 and the upper assembly link component 310. The top hinge structure 416 includes a hole 422 formed therein to accommodate a hinge pin, rod, bolt, or any suitably configured fastener or coupling element. Similarly, the bottom hinge structure 418 includes a hole 424 formed therein to accommodate another hinge pin, rod, bolt, fastener, coupling element, etc. A line passing through the center of the hole 422 corresponds to the top hinge rotation axis 426, and a line passing through the center of the hole 424 corresponds to the bottom hinge rotation axis 428 (see figure). Figure 27 ).

[0108] The top and / or front section of link component 410 may include any number of threaded holes 432 or threaded inserts to facilitate attachment to mounting bracket assembly 412. Although not used in the illustrated embodiment, the sides of link component 410 may be suitably configured to allow it to receive decorative end caps (as described above with reference to end cap 216 for lower assembly 202). Figure 28 As shown, one of the two link components 410 includes a threaded insert 434 that is installed in holes 422, 424.

[0109] For further reference Figure 31 Link component 410 includes a structural interlocking feature 440 for leading edge assembly 402. Note that the structural interlocking feature 440 is shaped, sized, arranged, and configured to cooperate with the structural interlocking feature 240 of link component 210 of lower assembly 202 and / or with the structural interlocking feature 340 of link component 310 of upper assembly 302. When deployed in the assembled load-bearing support mechanism, the structural interlocking feature 440 is oriented as a rearward-facing structural feature. According to the illustrated embodiment, the structural interlocking feature 440 includes, but is not limited to, a slightly upwardly extending protrusion 444. Figures 26-28 As shown, protrusion 444 resides between the top and bottom hinge structures 416, 418. Protrusion 444 forms a shelf that defines a pocket space 446 above the shelf and below the top section of the link member 410. Pocket space 446 is shaped, sized, and configured to receive protrusion 244 of the lower component link member 210.

[0110] Figure 29 and Figure 30 It is a perspective view depicting the assembly steps associated with the manufacturing of the leading edge component 402. Figure 29 Four link components 410 are shown coupled to the mounting bracket assembly 412 (e.g., used in...). Figure 29(Screws or bolts hidden in the view). Figure 29 The front trim piece 414-1 is shown attached to the mounting bracket assembly 412, and Figure 30 The front trim piece 414-1 is shown after being attached via threaded fastener 450. Figure 30 It also includes a top trim member 414-2, shown prior to attachment to the top of the mounting bracket assembly 412. In some embodiments, the top trim member 414-2 is attached to the mounting bracket assembly 412 using a suitable adhesive or bonding material. Figure 25 The completed leading edge assembly 402 is shown in the figure. (See figure for details.) Figure 31 As depicted, the leading edge component 402 is coupled to the last instance of the lower component 202 and the last instance of the upper component 302 via various link components 210, 310, 410.

[0111] Figures 32-34 An exemplary embodiment of a load-bearing support structure 500 with a deformable support mechanism 502 is depicted, which utilizes multiple lower components 202, multiple upper components 302, and a leading edge component 402. For simplicity and ease of description, the support structure 500 is depicted as having no surrounding structures or associated storage units. Furthermore, relative to... Figures 1-3 In the implementation shown, the orientation of the retraction and folding of the deformable support mechanism 502 is simplified.

[0112] The support structure 500 includes a plurality of upper components 302 hinged together in series, such that the leading edge segment 306 of a rear instance of an upper component 302 is coupled to the trailing edge segment 308 of a front instance of an upper component 302. As described above, the upper components 302 are coupled together via a front hinge structure 326 and a rear hinge structure 328 and bolts 372. In this respect, the front hinge structure 326 is located at the leading edge segment 306 of the upper component, and the rear hinge structure 328 is located at the trailing edge segment 308 of the upper component. Similarly, the support structure 500 includes a plurality of lower components 202 hinged together in series, such that the leading edge segment 206 of a rear instance of a lower component 202 is coupled to the trailing edge segment 208 of a front instance of a lower component 202. As described above, the lower components 202 are coupled together via a front hinge structure 226 and a rear hinge structure 228 and bolts 272. In this respect, the front hinge structure 226 is located at the leading edge section 206 of the lower assembly, and the rear hinge structure 228 is located at the trailing edge section 208 of the lower assembly.

[0113] refer to Figure 39 , Figure 40 and Figure 43The link arrangement of the upper component 302 terminates at the final upper component 302-1, and the link arrangement of the lower component 202 terminates at the final lower component 202-1. The final components 202-1 and 302-1 are coupled to the leading edge component 402 via their respective final chain links 274 and 374. More specifically, the link component 210 of the final lower component 202-1 and the link component 310 of the final upper component 302-1 are coupled to the link component 410 of the leading edge component 402, wherein the two link components 410 cooperate to form the leading edge link of the leading edge component 402 (see...). Figure 31 (and the related description above).

[0114] When assembled and deployed as described herein, the lower link component 210 and the upper link component 310 are configured to function as chain links articulated together in series. The illustrated embodiment includes two upper chain assemblies (left and right sides) formed by the upper link component 310, and two lower chain assemblies (left and right sides) formed by the lower link component 210. Each upper chain link implemented by the two upper link components 310 includes an outward-facing structural feature and an inward-facing structural feature opposite to its outward-facing structural feature. Similarly, each lower chain link implemented by the two lower link components 310 includes an outward-facing structural feature and an inward-facing structural feature opposite to its outward-facing structural feature.

[0115] The inward-facing structural features of the upper link component 310 (e.g., hook / finger structure 342) and the inward-facing structural features of the lower link component 210 (e.g., hook / finger structure 242) are configured to be releasably coupled together in response to cooperative movement of the upper and lower chain assemblies along a predefined unfolding path. Conversely, the inward-facing structural features of the upper link component 310 (e.g., hook / finger structure 342) and the inward-facing structural features of the lower link component 210 (e.g., hook / finger structure 242) are configured to be separated and decoupled from each other in response to cooperative movement of the upper and lower chain assemblies along a predefined retracting path.

[0116] The outward-facing structural features of the upper link component 310 (e.g., slot 334) can be used to couple the working surface sub-component 336 to the upper chain link. For example... Figure 33 As shown, the multiple unfolded working surface sub-components 336 cooperate to form an unfoldable working surface 504 of the support structure 500. When the upper and lower chain assemblies are unfolded and coupled together in the manner described herein, the corresponding hook / finger structures 242, 342 interlock with each other for self-support. As a result, the unfoldable working surface 504 is load-bearing when placed in the unfolded position. According to the depicted embodiment, the unfolded portion of the support structure 500 accommodates the load on the working surface 504 and the load of the structure below / opposite the working surface 504.

[0117] Figures 39-41This demonstrates how the upper link component 310 and the lower link component 210 cooperate with each other to transition from a decoupled and isolated state to a coupled and interlocked state. For clarity and simplicity, Figures 39-41 Some components that appear in other figures are not shown. Figures 39-41 and Figures 32-34 The orientation of the support structure 500 shown is consistent. In this respect, Figure 39 This is the side view corresponding to the first position. Figure 40 It is a side view corresponding to the second position, and Figure 41 This is a side view corresponding to the third position. The first position can represent the initial state before the deformable support mechanism is deployed, the second position can represent the intermediate state (after deployment begins), and the third position can represent the final deployed position.

[0118] exist Figure 39 and Figure 40 In the middle, the hook / finger structure of the leftmost link member 210 and the protrusion of the leading edge link member 410 are fully coupled and interlocked together. Note that the shape of the hook / finger structure closely matches the shape of the pocket space defined in the leading edge link member 410, such that the hook / finger structure occupies most (if not all) of the pocket space. This tight assembly is desired to hold the final lower assembly 202-1 in place and to prevent the final lower assembly 202-1 from rotating about its front hinge axis of rotation. Figure 39 In the middle, the hook / finger structure of the leftmost upper link component 310 has not yet fully engaged with the hook / finger structure of the paired lower link component 210, and some space can be seen near the corresponding protrusion. However, in Figure 40 In this configuration, there is almost no space between these protrusions (as shown, extending in opposite directions when unfolded). Therefore, the shape of the hook / finger structure of the lower link member 210 closely matches the shape of the pocket space defined in the corresponding upper link member 310, such that the hook / finger structure occupies most (if not all) of the pocket space. Similarly, the shape of the hook / finger structure of the upper link member 310 closely matches the shape of the pocket space defined in the corresponding lower link member 210, such that the hook / finger structure occupies most (if not all) of the pocket space. Therefore, when a pair of upper and lower link members 310, 210 are fully engaged and interlocked in this manner, the cooperative structure inhibits rotation of the associated upper and lower components 302, 202.

[0119] Figures 39-42 The sequence demonstrates how the inward-facing features of the upper and lower components 302, 202 dynamically interact and engage in response to the cooperative movement of the upper and lower components 302, 202 along a predefined unfolding path. Figures 42-39The reverse sequence demonstrates how the inward-facing features of the upper and lower components 302, 202 dynamically interact and disengage in response to the cooperative movement of the upper and lower components 302, 202 along a predefined collapse path. For this particular embodiment, the unfold and collapse paths follow a common path but in opposite directions. Figures 39-41 As shown, the movement of the upper and lower components 302, 202 along the deployment path causes them to move closer together, resulting in the pivoting of the lower link component 210 until the hook / finger structure of the lower link component 210 engages with the corresponding hook / finger structure of the upper link component 310 and ultimately interlocks. This interlocking feature prevents rotation of individual link components, thus creating a rigid link structure from the upper and lower components 302, 202. The offset position of the joints (hinge axes) in the relative components 302, 202 inhibits vertical movement. As a result, the interlocking components 302, 202 are rigid in all directions: upward; downward; and left and right.

[0120] refer to Figures 32-38 , Figure 42 and Figure 43 The support structure 500 includes a guide rail arrangement 508 having at least one guide rail 510. The depicted embodiment includes two guide rails 510—one for the left chain assembly and one for the right chain assembly. The guide rail arrangement 508 is suitably configured to receive upper and lower assemblies 302, 202 and is designed to accommodate sliding movements of the upper and lower assemblies 302, 202 required for the deployment and retraction of the deformable support mechanism 502. More specifically, each guide rail 510 is configured to receive an upper chain assembly (formed by an upper link member 310) and a lower chain assembly (formed by a lower link member 210), and each guide rail 510 accommodates sliding movements of the chain assemblies as needed. To this end, each guide rail 510 is shaped, sized, and arranged in a desired manner to define and provide predefined deployment and retraction paths for the upper and lower assemblies 302, 202.

[0121] Each guide rail 510 is also shaped, sized, arranged, and configured to, in response to cooperative movement of the chain assembly along an unfolding path defined by the guide rail 510, transition the inward-facing structural features of the upper chain link (e.g., protrusion 344) and the inward-facing structural features of the lower chain link (e.g., protrusion 244) from a decoupled state to a coupled state. Similarly, each guide rail 510 is shaped, sized, arranged, and configured to, in response to cooperative movement of the chain assembly along a retracting path defined by the guide rail 510, transition the inward-facing structural features of the upper chain link (e.g., protrusion 344) and the inward-facing structural features of the lower chain link (e.g., protrusion 244) from a coupled state to a decoupled state. Figures 39-41 The coupling / decoupling actions resulting from this cooperative movement are described.

[0122] refer to Figures 35-38 , Figure 42 and Figure 43 Each guide rail 510 of the illustrated support structure 500 includes various structural features that hold and guide the lower and upper components 202, 302 as they move along the guide rail 510. Depending on the specific embodiment, the guide rail 510 may include any, but not limited to, and in any desired combination of the following structural features: one or more channels, one or more flanges, one or more rails, one or more tracks, one or more tunnels, one or more slots, one or more keys / keyways, one or more protrusions, one or more ribs, one or more grooves, etc.

[0123] Although not always necessary, when viewed in cross-section along a line or plane perpendicular to the main longitudinal axis of the guide rail 510, the depicted embodiment of the guide rail 510 has a shape similar to an I-beam. Figure 37 Depicting from Figure 36 The I-beam shape 514 is observed along line AA. The I-beam shape 514 is generally characterized by an upper flange 516, a lower flange 518 opposite to the upper flange 516, and a web 520 between the upper and lower flanges 516, 518. Although the web 520 is hollow in the depicted embodiment, it can be a solid web in other embodiments. The flanges 516, 518 and the web 520 cooperate to define a channel 522 opening on the right side and a channel 524 opening on the left side. The web 520 separates the two channels 522, 524 such that channel 522 opens to the right side of guide rail 510 and channel 524 opens to the left side of guide rail 510. Guide rail 510 has a main longitudinal axis 526, which is generally defined by a line centered in the web 520, following a path defined by the web 520 (see...). Figure 35 It shows the longitudinal axis 526 for entering and exiting the guide rail 510. In some exemplary embodiments, the guide rail 510 employs a curved main longitudinal axis 526 that accommodates the folded storage of the first and second chain assemblies when they are decoupled from each other, and thus accommodates the folded storage of the corresponding lower and upper assemblies 202, 302. However, Figures 32-38 The guide rail 510 shown stores most of the lower and upper components 202, 302 in a straight and folded state (except for the section residing in the curved neck region of the guide rail 510). For comparison, Figure 3 The guide rails used in the version shown are curved to accommodate a bent and folded configuration when stowed.

[0124] Figure 38 This illustrates how the lower and upper components 202 and 302 (coupled together) are introduced onto the guide rail 510. The coupled components 202 and 302 can be aligned with the guide rail 510 and moved laterally (in... Figure 38(From center to right) to engage the end of guide rail 510. Components 202 and 302 can be mounted onto guide rail 510 and moved... Figure 34 The retracted position is shown. As mentioned earlier, the movement of components 202 and 302 in the retracted direction results in the decoupling of components 202 and 302.

[0125] Figure 42 and Figure 43 The manner in which spring assemblies 212, 312 engage with guide rail 510 is shown. As described above, each lower chain link of lower assembly 202 includes two spring assemblies 212 (each spring assembly 212 has a leaf spring 252). Similarly, each upper chain link of upper assembly 302 includes two spring assemblies 312 (each spring assembly 312 also has a corresponding leaf spring). Spring assemblies 212 engage at least the lower flange 518 of guide rail 510 to hold the retracted portion of lower assembly 202 and its lower chain assembly on guide rail 510 in a retracted state. Similarly, spring assemblies 312 engage at least the upper flange 516 of guide rail 510 to hold the retracted portion of upper assembly 302 and its upper chain assembly on guide rail 510 in a retracted state. See also... Figure 14 The bottom surface of the spring assembly 212 engages with and slides on the surface of the lower flange 518 defining the channels 522, 524, while the hollow roller 270 engages with and rolls on the outward-facing surface of the lower flange 518. When mounted on the guide rail 510, the two opposing spring assemblies 212 are laterally connected to the web 520 (the web 520 will reside on...). Figure 14 (In the space between spring assemblies 212-1 and 212-2 shown). The spring tension provided by leaf spring 252 "clamps" the lower flange 518 between spring assembly 212 and hollow roller 270. For upper assembly 302, spring assembly 312 is used to "clamp" the upper flange 516 of guide rail 510 between spring assembly 312 and hollow roller 370.

[0126] Guide rail 510 includes a curved neck region 530 (see...) Figure 38 This serves as a transition for coupling / decoupling the lower and upper components 202, 302. For the depicted embodiment, the first end 532 of the curved neck region 530 is associated with a relatively wide spacing between the upper and lower flanges 516, 518 of the guide rail, and the second end 534 of the curved neck region 530 is associated with a relatively narrow spacing between the upper and lower flanges 516, 518. The wide spacing keeps the lower and upper components 202, 302 decoupled and spaced apart from each other, while the narrow spacing allows the lower and upper components 202, 302 to engage in a coupled state. The curved neck region 530 allows the lower and upper components 202, 302 to transition from a decoupled state to a coupled state (and vice versa) in response to coordinated movement during deployment and retraction, as referenced above. Figures 39-41As explained, the shape of the curved neck region 530 and the variable spacing between the upper and lower flanges 516, 518 push the lower and upper components 202, 302 into the desired position as they move cooperatively during extension and retraction. When moving in the unfolding direction, the lower component 202 moves closer to the upper component 302, and the hook / finger structure 242 of the lower component 202 pivots to enter the pocket space 346 of the upper component 302, and ultimately fully engages the hook / finger structure 342 of the upper component 302. When moving in the retracting direction, the lower component 202 moves away from the upper component 302, and the hook / finger structure 242 of the lower component 202 pivots and naturally disengages and “detaches” from the hook / finger structure 342 of the upper component 302. See again. Figures 39-41 It demonstrated this activity.

[0127] When the support mechanism 502 is deployed, some of the link components 210, 310 remain uncoupled (carried by the guide rail arrangement 508), and one or more pairs of link components 210, 310 may be in a partially coupled state. When the upper and lower components 302, 202 are decoupled, they are constrained to the path identified by the guide rail 510. An extension section of the guide rail 510 containing a portion of the mating components 302, 202 transmits torque to the guide rail 510. The system is designed to ensure that force is transmitted through the upper and lower components 302, 202 to the guide rail 510, which holds the deployed portion of the support mechanism 502 in place.

[0128] Although not implemented using the illustrated embodiment, the load-bearing support structure 500 may include storage units that are appropriately configured to surround the guide rail 510, either wholly or partially. The storage units are shaped and sized to accommodate the retraction of the deformable support mechanism 502 (including the chain assembly, upper and lower assemblies 302, 202, etc.) in the retracted state. Furthermore, the storage units may include openings defined or formed therein, which are shaped and sized to accommodate the passage of the deformable support mechanism 502 when the upper and lower assemblies 302, 202 are coupled together in the deployed state. See, for example, [link to relevant documentation]. Figure 1 and Figure 2 The example shown.

[0129] Second Embodiment

[0130] Figures 44-79Various structures and features associated with embodiments of a load-bearing support structure are described, which employs at least one deformable support mechanism having structural features similar to a truss structure, wherein the elements of the truss structure interlock with each other when the support structure is deployed. Many aspects of the first and second embodiments are common. In fact, some structural, identical, or equivalent structural features and functional characteristics of the second embodiment of the support structure are similar to, identical to, or equivalent to those described above with respect to the first embodiment of the support structure. For simplicity and brevity, in the context of the second embodiment, such similar, identical, or equivalent aspects will not be described in redundant detail herein.

[0131] Figure 44 This is a perspective top rear view applicable to the lower component 602 used with the disclosed embodiments, and Figures 45-50 Various components and sub-components of the lower assembly 602 are depicted. As explained in more detail below, embodiments of the load-bearing support structure utilize multiple such lower assemblies 602 that are hinged together in series to form part of a deformable support mechanism. The depicted embodiments of the lower assembly 602 include, but are not limited to: link component 610; lower support slats 614; and end caps 616. These main components of the lower assembly 602 are coupled together using appropriate hardware, sub-components, and / or materials.

[0132] For this particular embodiment, the link component 610 is the same, and the lower assembly 602 includes three link components (one on the left or near the left, one on the right or near the right, and one located between the left and right). Although Figure 44 An arrangement including three link components 610 is depicted, but alternative embodiments of the lower assembly may include only one lower link component or more than three lower link components, which is suitable for specific use cases, intended applications of load-bearing support structures, shapes and sizes of deployable support surfaces, and various strength, durability and load-bearing capacity requirements.

[0133] As shown and described in more detail below, link member 610 is suitably configured and arranged to form a front hinge structure and a rear hinge structure for the lower assembly. The front hinge structure is located at or near the front edge section of the lower assembly 602, and the rear hinge structure is located at or near the rear edge section of the lower assembly 602. The front hinge structure of the lower assembly 602 is configured to provide a front hinge axis of rotation, and the rear hinge structure of the lower assembly 602 is configured to provide a rear hinge axis of rotation. When multiple lower assemblies 602 are hinged together in series, the hinge structures allow adjacent lower assemblies 602 to rotate relative to each other on the front and rear hinge axes of rotation. This hinge arrangement facilitates compact (folded or bent) storage of the lower assemblies 602 if desired.

[0134] Figures 45-48Different views of a link component 610 (for lower component 602) are depicted.

[0135] Figure 45 It is a perspective top view. Figure 46 It is a perspective view from below. Figure 47 It is a side view, and Figure 48 This is a top view. The link component 610 can be made of any suitable material with the desired strength and toughness, such as aluminum, nylon, composite materials, plastics, etc.

[0136] This figure illustrates the structural features of the lower assembly front hinge structure 626 and the lower assembly rear hinge structure 628 forming the lower assembly 602. The front hinge structure 626 and the rear hinge structure 628 are offset relative to each other. This offset configuration accommodates a link / hinge of multiple link components 610 connected in series. The front hinge structure 626 includes a hole 630 formed therein to receive a hinge pin, rod, bolt, or any suitably configured fastener or coupling element. Similarly, the rear hinge structure 628 includes a hole 632 formed therein to receive another hinge pin, rod, bolt, fastener, coupling element, etc. A line passing through the center of the hole 630 corresponds to the front hinge rotation axis, and a line passing through the center of the hole 632 corresponds to the rear hinge rotation axis.

[0137] The base of the link component 610 includes a groove 634 formed therein. At least one groove 634 is shaped, sized, and configured to receive a portion of the lower support strip 614, and at least one groove 634 is shaped, sized, and configured to receive a bracket for mounting the end cap 616 (see [link]). Figure 49 and Figure 50 According to the depicted embodiment, the base of the link component 610 is symmetrical and has two identical grooves 634 formed therein; the ends of the lower support strip 614 and the mounting bracket are similarly shaped and sized to fit into the grooves 634. The base of the link component 610 may also include any number of threaded holes 636 (in... Figure 48 (marked) or insert to receive threaded fasteners for coupling the lower support strip 614 and the mounting bracket to the link assembly 610. For example... Figure 44 As shown, each of the two outermost link components 610 has an end cap 616 and a lower support strip 614 attached thereto, while the center link component 610 has two lower support strips 614 and no end cap 616 attached thereto. In the illustrated implementation, the end caps 616 are decorative end caps that, when unfolded, cooperate to provide an exposed sidewall surface for the lower assembly 602 (see...). Figure 2 and Figures 69-72 ).

[0138] Link member 610 includes a base 638 having an outward-facing surface 640 and an inward-facing surface 642. In the depicted embodiment, the edge of the slot 634 terminates at the outward-facing surface 640, and link member 610 includes suitably configured and arranged protrusions 644 extending in a direction away from the inward-facing surface 642. In other words, the protrusions 644 rise above and extend from the inward-facing surface 642. Disclosed implementations of the protrusions 644 include two protrusions of similar shape, size, and configuration (located on or near either side of link member 610). Reference Figure 47 The protrusion structure 644 has a non-uniform side profile shape, characterized by: a lower region resembling a truncated triangle; and an upper region resembling a truncated inverted triangle. The lower region extends upward from the base 638 and from its widest width at or near the base 638 ( Figure 47 The horizontal dimension of the protrusion 644 is transformed to its narrowest width at the neck region 646. The neck region 646 corresponds to the junction between the upper and lower regions of the protrusion 644. In this respect, the upper region transforms from its narrowest width at the neck region 646 to its widest width at or near the top surface 648 of the protrusion 644. The inclined sidewalls of the upper region form at least one chamfered segment 650 of the non-uniform side profile shape of the protrusion 644.

[0139] Link component 610 also includes a pin support 652, which is shaped, sized, and positioned to receive a guide pin (see...). Figure 49 and Figure 50 As described in more detail below, when the lower component 602 is installed for use with a load-bearing support structure, the guide pin is shaped, sized, configured, and positioned to engage the guide rail. The guide pin travels along the path defined by the guide rail, which in turn causes the link component 610 and the corresponding lower component 602 to travel in a predetermined and restricted manner.

[0140] Figure 49 and Figure 50 It is a perspective view depicting the assembly steps associated with the manufacture of the lower component 602. Figure 49 The link component 610 is shown after the guide pin 654 has been installed into the pin support 652. Figure 49 A hinge pin 656 is also shown mounted in one of the two hinge structures of the link component 610. The guide pin 654 and hinge pin 656 can be coupled to their respective support structures using any technique, such as press fit, threading, welding, joining, etc. It should be understood that multiple link components 610 are connected together in series using hinge pin 656. As described below, hinge pin 656 can also be used to connect link components 610 to the hinge structure of the leading edge assembly. Figure 49Also shown is a bracket 658 and a threaded fastener 660, which can be used to secure the end cap 616 to the bracket 658. Figure 49 The end section of the lower support strip 614 is also shown, which is shaped and sized to fit into a slot 634 in the link member 610.

[0141] Figure 50 Depicting the already installed Figure 49 The lower assembly 602 is located on one side following the component shown. Threaded fasteners 662 can be used to attach the lower support strip 614 to the link assembly 610 and to attach the bracket 658 (with end cap 616) to the link assembly 610. Reference Figure 44 Similarly, the opposite sides of the lower assembly 602 are constructed using a second lower support strip 614. The two lower support strips 614 are combined with a third instance of the link component 610.

[0142] Figures 51-56 Exemplary embodiments relating to the upper component 702 used in conjunction with the disclosed second embodiment. Figure 51 It is a perspective top view of the upper component 702, and Figures 52-56 Various parts and sub-assemblies of the upper component 702 are depicted. As explained in more detail below, embodiments of the load-bearing support structure utilize multiple such upper components 702, which are hinged together in series, to form part of a deformable support mechanism. Some structural, features, and functional characteristics of the upper component 702 are similar, identical, or equivalent to those described above with respect to the lower component 602. For the sake of simplicity and brevity, in the context of the upper component 702, such similar, identical, or equivalent aspects will not be described in redundant detail here.

[0143] The depicted embodiment of the upper assembly 702 includes, but is not limited to, a link member 710; and an upper support strip 714 (or an equivalent support sub-member), which cooperate to form a deployable support surface when deployed. These main components of the upper assembly 702 are coupled together using appropriate hardware, sub-components, and / or materials.

[0144] For this particular embodiment, the link component 710 is the same, and the upper assembly 702 includes three link components (one on the left or near the left, one on the right or near the right, and one located between the left and right). Although Figure 51 An arrangement including three link components 710 is depicted, but alternative embodiments of the upper component may include only one upper link component or more than three upper link components, which is suitable for specific use cases, intended applications of load-bearing support structures, shapes and sizes of deployable support surfaces, and various strength, durability and load-bearing capacity requirements.

[0145] As shown and described in more detail below, link component 710 is suitably configured and arranged to form a front hinge structure and a rear hinge structure for the upper assembly. The front hinge structure is located at or near the front edge section of the upper assembly, and the rear hinge structure is located at or near the rear edge section of the upper assembly. The front hinge structure of the upper assembly 702 is configured to provide a front hinge axis of rotation, and the rear hinge structure of the upper assembly 702 is configured to provide a rear hinge axis of rotation. When multiple upper assemblies 702 are hinged together in series, the hinge structures allow adjacent upper assemblies 702 to rotate relative to each other on the front and rear hinge axes of rotation. This hinge arrangement facilitates compact (folded or bent) storage of the upper assemblies 702 if desired.

[0146] Figures 52-55 Different views of a link component 710 (for upper component 702) are depicted. Figure 52 It is a top-down perspective view. Figure 53 It is a perspective view taken from below. Figure 54 It is a side view, and Figure 55 This is a top view. The figure illustrates the structural features of the upper component front hinge structure 726 and the upper component rear hinge structure 728 forming the upper component 702. The front and rear hinge structures 726 and 728 are offset relative to each other to accommodate a link / hinge of multiple link components 710 connected in series. The front hinge structure 726 includes a hole 730 formed therein to accommodate a hinge pin, rod, bolt, or any suitably configured fastener or coupling element. Similarly, the rear hinge structure 728 includes a hole 732 formed therein to accommodate another hinge pin, rod, bolt, fastener, coupling element, etc. A line passing through the center of the hole 730 corresponds to the front hinge rotation axis, and a line passing through the center of the hole 732 corresponds to the rear hinge rotation axis.

[0147] The base of the link component 710 includes a groove 734 formed therein. At least one groove 734 is shaped, sized, and configured to receive a portion of the upper support strip 714, and at least one groove 734 is shaped, sized, and configured to receive a magnet for securing a flexible working surface component to the upper assembly (see [link]). Figure 56 According to the depicted embodiment, the base of the link component 710 is symmetrical and has two identical slots 734 formed therein; the ends of the upper support strips 714 and the magnets are similarly shaped and sized to fit into the slots 734. The base of the link component 710 may also include any number of threaded holes 736 (in... Figure 55 (marked) or insert to receive threaded fasteners for coupling the upper support strip 714 to the link assembly 710. For example... Figure 51As shown, each of the two outermost link components 710 has a magnet 737 attached thereto and an upper support strip 714, while the central link component 710 has two upper support strips 714 and no magnet 737 attached thereto.

[0148] Link member 710 includes a base 738 having an outward-facing surface 740 and an inward-facing surface 742. In the depicted embodiment, the edge of the slot 734 terminates at the outward-facing surface 740, and the link member 710 includes suitably configured and arranged protrusions 744 extending in a direction away from the inward-facing surface 742. In other words, the protrusions 744 rise above and extend from the inward-facing surface 742. Disclosed implementations of the protrusions 744 include two protrusions of similar shape, size, and configuration (located on or near either side of the link member 710). Reference Figure 54 The protrusion structure 744 has a non-uniform side profile shape similar to a truncated inverted triangle. The truncated triangular region of the protrusion structure 744 extends upward from the base 738 and from its narrowest width at or near the base 738 ( Figure 54 The horizontal dimension of the protrusion 744 is converted to its widest width at or near the top surface 748 of the protrusion 744. The inclined sidewalls of the truncated triangular region form at least one chamfered segment 750 of the non-uniform side profile shape of the protrusion 744.

[0149] The link component 710 also includes an alignment tab 751, which can be formed as part of the protrusion structure 744. For example... Figures 52-55 As shown, the link component 710 includes four alignment tabs 751 located inside the protrusions. Each alignment tab 751 provides an outward-facing support surface that restricts the lateral movement of the cooperating link component 610. Furthermore, when the upper component 702 mates with the lower component 602, each trapezoidal protrusion of the link component 710 acts as a wedge (see...). Figure 76 and Figure 77 When components 602 and 702 are joined together in this manner, the alignment tab 751 provides alignment assistance to the lower link component 610 and inhibits the left and right movement of the mating link components 610 and 710.

[0150] Link component 710 also includes a pin support 752, which is shaped, sized, and positioned to receive a guide pin (see...). Figure 56 When the upper component 702 is installed for use with a load-bearing support structure, the guide pin engages the guide rail. The guide pin travels along the path defined by the guide rail, which in turn causes the link component 710 and the corresponding upper component 702 to travel in a predetermined and restricted manner.

[0151] Figure 56It is an exploded perspective view depicting the assembly steps associated with the manufacture of the upper component 702. Figure 56 The link component 710 is shown after the guide pin 754 has been installed into the pin support 752. Figure 56 A hinge pin 756 is also shown, mounted in one of the two hinge structures of the link component 710. Multiple link components 710 are connected together in series using the hinge pin 756. As described below, the hinge pin 756 can also be used to connect the link component 710 to a hinge structure of the leading edge assembly. Figure 49 A magnetic block 737 is also shown, which is assembled in one of the slots 734. The magnetic block 737 can be fixed to the link component 710 by means of press fit, bonding or adhesive materials, fasteners, snap fit, etc. Figure 56 The end section of the upper support strip 714 is also shown, which is shaped and sized to fit into a slot 734 in the link component 710. Threaded fasteners 758 can be used to attach the upper support strip 714 to the link component 710.

[0152] Figure 51 Depicting the already installed Figure 56 The upper assembly 702 follows the component shown. Link components 710 at the left and right sides of the upper assembly 702 are each coupled to an upper support strip 714 and a magnet 737. The two upper support strips 714 are coupled to a third instance of the link component 710 (which has no magnet 737).

[0153] Figures 57-64 Exemplary embodiments relating to a leading edge assembly 802 suitable for use with the disclosed second embodiment are described. Figure 57 This is a perspective rear view of the leading edge component 802, and Figures 58-64 Various parts and sub-assemblies of the leading edge assembly 802 are depicted. Some structural features, characteristics, and functional properties of the leading edge assembly 802 are similar, identical, or equivalent to those described above for the lower assembly 602 and / or the upper assembly 702. For the sake of simplicity and brevity, in the context of the leading edge assembly 802, such similar, identical, or equivalent aspects may not be described in redundant detail here.

[0154] The depicted embodiment of leading edge assembly 802 includes, but is not limited to: right leading edge link member 804; left leading edge link member 806; middle leading edge link member 808; mounting bracket assembly 812; and at least one decorative member ( Figure 57 Not shown in the image, but Figures 69-72 (As shown in the diagram), it includes or is made of decorative materials. These main components of the leading edge assembly 802 are coupled together using appropriate hardware, sub-components, and / or materials. Although Figure 57An arrangement comprising three leading-edge link components is depicted, but alternative embodiments of the leading-edge assembly may include only one leading-edge link component or more than three leading-edge link components, which is suitable for specific use cases, intended applications of load-bearing support structures, shapes and sizes of deployable support surfaces, and various strength, durability, and load-bearing capacity requirements.

[0155] See below for reference. Figures 65-68 As shown and described in more detail, link components 804, 806, and 808 are suitably configured and arranged to form a top hinge structure and a bottom hinge structure for the leading edge assembly 802. The top hinge structure is arranged and configured for compatibility with link component 710 of the upper assembly 702, and the bottom hinge structure is arranged and configured for compatibility with link component 610 of the lower assembly 602. These hinge structures facilitate rotation of the corresponding upper and lower assemblies 702, 602 about a respective hinge rotation axis defined by the hinge structure.

[0156] Figures 58-61 Different views of the right leading edge link component 804 are depicted. The left leading edge link component 806 is similarly configured, with some features and structures rearranged to accommodate the asymmetrical nature of the right and left leading edge link components 804, 806. Figure 58 It is a rear perspective view. Figure 59 It is a front perspective view. Figure 60 It is a rear view, and Figure 61 This is a bottom view. The figure illustrates the structural features of the top hinge structure 816 and the bottom hinge structure 818 forming the leading edge assembly 802. The top and bottom hinge structures 816 and 818 are offset relative to each other to accommodate the linking / hinging of the upper and lower assemblies 702 and 602. The top hinge structure 816 includes a hole 822 formed therein to accommodate a hinge pin, rod, bolt, or any suitably configured fastener or coupling element. Similarly, the bottom hinge structure 818 includes a hole 824 formed therein to accommodate another hinge pin, rod, bolt, fastener, coupling element, etc. A line passing through the center of the hole 822 corresponds to the top hinge rotation axis 826, and a line passing through the center of the hole 824 corresponds to the bottom hinge rotation axis 828.

[0157] The illustrated embodiment of link member 804 includes a contour recess 830 formed therein. As... Figure 59 As shown, the profile recess 830 curves from the top of the link member 804 toward the rear. The profile recess 830 is shaped, sized, and positioned to receive the end section of the mounting bracket assembly 812 (see Figure 830). Figure 64To this end, link component 804 may include any number of threaded holes 832 or threaded inserts to facilitate attachment to mounting bracket assembly 812. Link component 804 may also include any number of additional threaded inserts, threaded holes, and / or through holes 834 to facilitate attachment of other components, such as trim pieces, mounting hardware, handles or knobs, decorative outer surface sheets, etc., during assembly of the resulting support mechanism. Although not used in the illustrated embodiment, the sides of link component 804 may be suitably configured to allow it to receive decorative end caps.

[0158] Link member 804 includes a structural interlocking feature 840 for leading edge assembly 802. Note that the structural interlocking feature 840 is shaped, sized, arranged, and configured to cooperate with the protrusion structure 644 of link member 610 of lower assembly 602 and / or with the protrusion structure 744 of link member 710 of upper assembly 702. In the illustrated embodiment, the structural interlocking feature 840 has a side profile shape that matches the side profile shape of the protrusion structure 644 (a triangular notch receives the top section of the protrusion structure 644, a triangular point receives the neck region 646 of the protrusion structure 644, and a long inclined wall follows the angled sidewalls of the protrusion structure 644). This interlocking arrangement holds link member 610 in place and prevents link member 610 from rotating relative to link member 804 about the hinge axis. Figure 66 and Figure 67 Link component 610 that mates with corresponding link components 804, 806, and 808 is depicted.

[0159] Figure 62 This is a perspective rear view of an embodiment of the intermediate leading edge link component 808, and Figure 63 This is a top view of link component 808. Link component 808 shares many features, structures, and functions with link component 804, and those common aspects will not be described in detail redundantly here. For example, link component 808 includes: a top hinge structure 846 providing a top hinge rotation axis 826; a bottom hinge structure 848 providing a bottom hinge rotation axis 828; a profile recess 850 for receiving mounting bracket assembly 812; and a structural interlocking feature 852 cooperating with structural features of link component 610 of lower assembly 602. Note that the intermediate leading edge link component 808 includes two profile recesses 850 to facilitate engagement of the two mounting bracket assemblies 812 together, such as... Figure 57 and Figures 65-68 As shown.

[0160] refer to Figure 57 and Figure 64 , through Figure 57The arrangement shown couples two mounting bracket assemblies 812 to link components 804, 806, 808 to create the leading edge assembly 802. Threaded fasteners 854 can be used to secure the ends of the mounting bracket assemblies 812 to their respective link components. Figures 65-70 It is a perspective view depicting the manufacturing steps involved in the leading edge assembly. Figure 65 The leading edge assembly 802 and the lower assembly 602 are shown before they are coupled together. For visibility, one of the end caps 616 is missing from the depicted lower assembly 602. Figure 66 A leading edge assembly 802 and a lower assembly 602 coupled together are shown. For this purpose, the front hinge structure 626 of the lower assembly 602 mates with the bottom hinge structure 818 of the leading edge assembly 802 and is held together using appropriate hinge pins, bolts or rods. Figure 67 The state after the introduction of the upper assembly 702 is depicted. For this purpose, the front hinge structure 726 of the upper assembly 702 mates with the top hinge structure 816 of the leading edge assembly 802 and is held together using appropriate hinge pins, bolts, or rods. When assembled in this manner, the rear section of the protrusion 644 mates with and engages with the front section of the protrusion 744, which inhibits rotation of the upper assembly 702 relative to the lower assembly 602 about the hinge axis. Figure 68 The state after the second end cap 616 is attached to the lower component 602 is depicted.

[0161] Figure 68 The image depicts three final link components 610 of three corresponding chain assemblies (created by multiple lower components 602 linked together in series) and three final link components 710 of three corresponding chain assemblies (created by multiple upper components 702 linked together in series). Figure 69 This is a front perspective view of the leading edge component 802 after multiple lower components 602 and multiple upper components 702 have been coupled together. Figure 69 The diagram shows the components in their unfolded state after the upper and lower components 702 and 602 have been coupled to each other in a load-bearing configuration.

[0162] Figure 69 A portion of a flexible working surface component 860 covering the unfolded upper component 702 is also shown. The flexible working surface component 860 may be made of a thin, flexible sheet of metal with an outer layer of decorative material applied thereto. Alternatively or additionally, the flexible working surface component 860 may be made of any flexible and bendable material that may be coated, painted, or otherwise treated to provide a suitable decorative appearance, pattern, or graphic on its outer surface. According to the illustrated embodiment, a front segment 862 of the flexible working surface component 860 is coupled to the leading edge component 802. The front segment 862 may be attached to the leading edge component 802 using one or more of mounting brackets, fasteners, clamping arrangements, bonding agents, adhesives, etc. Figure 70 The state after the front trim member 864 is attached to the leading edge assembly 802 is depicted. In some embodiments, the front trim member 864 is secured to the leading edge assembly 802 using fasteners passing through holes 834 located in the link members 804, 806, 808. When the support mechanism is deployed, at least some flexible working surface members 860 cover multiple deployed upper assemblies 702 to form deployed load-bearing working surfaces. When the support mechanism is retracted for storage, at least a portion of the flexible working surface members separates from the upper assembly 702 for storage in response to coordinated movement of the upper and lower assemblies 702, 602 along the retraction path. In the exemplary embodiments disclosed herein, when the support mechanism is deployed, a magnet 737 of the upper assembly 702 magnetically couples the bottom of the flexible working surface member 860 to the upper assembly 702. The magnetic coupling is disengaged in response to the retraction of the support mechanism, which facilitates the separation of the flexible working surface member 860 for compact storage where desired. In this respect, Figures 76-79 A portion of the flexible working surface component 860, separate from the upper component 702 below, is shown.

[0163] Figure 71 and Figure 72 An exemplary embodiment of a deformable load-bearing support mechanism 900 is depicted, which utilizes a plurality of lower components 602, a plurality of upper components 702, and a leading edge component 802. The support mechanism 900 and... Figure 1 and Figure 2 The load-bearing support structure 100 shown is consistent with and can be used with. For simplicity and ease of description, the support mechanism 900 is depicted as having no surrounding structure or associated storage unit.

[0164] The support mechanism 900 includes a plurality of upper components 702 hinged together in series and a plurality of lower components 602 hinged together in series. (Reference) Figures 76-79 The link arrangement of the upper component 702 terminates at the final upper component 702-1, and the link arrangement of the lower component 602 terminates at the final lower component 602-1. The final components 602-1 and 702-1 are coupled to the leading edge component 802 via their respective final link parts 610 and 710. More specifically, the link part 610 of the final lower component 602-1 and the link part 710 of the final upper component 702-1 are coupled to the link parts 804, 806, and 808 of the leading edge component 802.

[0165] When assembled and deployed as described herein, the lower link component 610 and the upper link component 710 are configured to function as chain links articulated together in series. The illustrated embodiment includes three upper chain assemblies (left, right, and middle) formed by the upper link component 710, and three lower chain assemblies (left, right, and middle) formed by the lower link component 610. Each upper chain link implemented by the upper link component 710 includes an outward-facing structural feature and an inward-facing structural feature opposite to its outward-facing structural feature. Similarly, each lower chain link implemented by the lower link component 610 includes an outward-facing structural feature and an inward-facing structural feature opposite to its outward-facing structural feature.

[0166] The inward-facing structural features of the upper link component 710 (e.g., protrusion 744) and the inward-facing structural features of the lower link component 610 (e.g., protrusion 644) are configured to be releasably coupled together in response to cooperative movement of the upper and lower chain assemblies along a predefined unfolding path. Conversely, the inward-facing structural features of the upper link component 710 and the inward-facing structural features of the lower link component 610 are configured to be separated and decoupled from each other in response to cooperative movement of the upper and lower chain assemblies along a predefined retracting path.

[0167] Multiple upper components 702 cooperate to form a deployable support surface of the support mechanism 900. More specifically, upper support slats 714 combine to form a deployable support surface (which may be covered by the flexible working surface component 860). When the upper and lower chain assemblies are deployed and coupled together in the manner described herein, corresponding protrusions 744, 644 interlock with each other for self-support. As a result, the deployable working surface is load-bearing when placed in the deployed position. According to the depicted embodiment, the deployed portion of the support mechanism 900 accommodates the load on the working surface and the load of structures below / opposite the working surface.

[0168] Figure 76 and Figure 77 This demonstrates how the upper link component 710 and the lower link component 610 cooperate with each other to transition between a decoupled and disconnected state and a coupled and interlocked state. For clarity and simplicity, Figure 76 and Figure 77 Some components that appear in other figures are not shown. Figure 76 This is a side view corresponding to the first position, which can represent the initial state of the deformable support mechanism 900 before it is deployed. Figure 77 This is a side view corresponding to the second position, which can represent the intermediate state after the unfolding begins.

[0169] exist Figure 77In this configuration, the protruding structures of the upper component 702-1 are fully coupled and interlocked with the protruding structures of the lower components 602-1 and 602-2. More specifically, the protruding structures of two adjacent lower link components 610 are laterally connected to and interlocked with the protruding structure of one upper link component 710. Similarly, the protruding structure of the lower component 602-2 is laterally connected to the protruding structures of the two upper components 702-1 and 702-2. As described above, when the support mechanism 900 is in the deployed state, the chamfered sections and features of the protruding structures engage, fit, and interlock with each other. This fit arrangement is desirable to hold the upper and lower components 702 and 602 in place and to inhibit rotation of components 702 and 602 relative to each other.

[0170] Figure 76 and Figure 77 The sequence demonstrates how the protruding structures of the upper and lower components 702, 602 dynamically interact and engage in response to the coordinated movement of the upper and lower components 702, 602 along a predefined unfolding path. Figure 76 and Figure 77 The reverse sequence demonstrates how the protruding structures of the upper and lower components 702, 602 dynamically interact and disengage in response to the coordinated movement of the upper and lower components 702, 602 along a predefined retractable path. For this particular embodiment, the unfolding and retracting paths follow a common path but in opposite directions. Figure 76 and Figure 77 As shown, the movement of the upper and lower components 702, 602 along the deployment path causes them to move closer together, and causes the lower link component 610 to pivot and move to align with the two side instances of the upper link component 710. Continuous movement along the deployment path brings the protruding structure into a fully coupled state.

[0171] refer to Figures 73-75 , Figure 78 and Figure 79 The support mechanism 900 cooperates with a guide rail arrangement having at least one guide rail 910. The disclosed embodiment includes three guide rails 910 – one for the left chain assembly, one for the right chain assembly, and one for the middle chain assembly. The guide rail arrangement is suitably configured to receive upper and lower assemblies 702, 602 and is designed to accommodate sliding movements of the upper and lower assemblies 702, 602 required for the deployment and retraction of the deformable support mechanism 900. More specifically, each guide rail 910 is configured to receive an upper chain assembly (formed by an upper link member 710) and a lower chain assembly (formed by a lower link member 610), and each guide rail 910 accommodates sliding movements of the chain assemblies as needed. To this end, each guide rail 910 is shaped, sized, and arranged in a desired manner to define and provide predefined deployment and retraction paths for the upper and lower assemblies 702, 602.

[0172] Each guide rail 910 is also shaped, sized, arranged, and configured to switch the upper component protrusion 744 and the lower component protrusion 644 from a decoupled state to a coupled state in response to coordinated movement of the chain assembly along an unfolding path defined by the guide rail 910. Similarly, each guide rail 910 is shaped, sized, arranged, and configured to switch the upper component protrusion 744 and the lower component protrusion 644 from a coupled state to a decoupled state in response to coordinated movement of the chain assembly along a retraction path defined by the guide rail 910. Figure 78 and Figure 79 The coupling / decoupling actions resulting from this cooperative movement are described.

[0173] Each guide rail 910 in the illustrated embodiment includes various structural features that hold and guide the lower and upper components 602, 702 as they move along the guide rail 910. Depending on the particular embodiment, the guide rail 910 may include any, but not limited to, and in any desired combination of the following structural features: one or more channels, one or more flanges, one or more rails, one or more tracks, one or more tunnels, one or more slots, one or more keys / keyways, one or more protrusions, one or more ribs, one or more grooves, etc.

[0174] Although not always necessary, the depicted embodiment of guide rail 910 includes a first keyway 920 formed therein, a second keyway 922 formed therein, and a third keyway 924 formed therein. Figure 75 As depicted in the cross-sectional view, the first and second keyways 920, 922 merge at an intersection 926 where they are continuous with the third keyway 924. Therefore, the third keyway 924 transforms and separates into the first and second keyways 920, 922. The guide rail 910 also includes an upper slit 928 and a lower slit 930. The upper slit 928 provides openings for direct access to the first keyway 920 and for direct access to the third keyway 924 (from above). The lower slit 930 provides openings for direct access to the second keyway 922 and for direct access to the third keyway 924 (from below).

[0175] The third keyway 924 receives guide pins 654 and 754 from link components 610 and 710; the upper and lower slits 928 and 930 receive upper and lower pin supports 752 and 652 (see...). Figure 50 and Figure 56This arrangement allows guide pins 654, 754 and pin supports 652, 752 to travel in a constrained and predefined manner defined by the third keyway 924. The first keyway 920 receives the guide pin 754 of the upper link member 710, and the upper slit 928 receives the pin support 752 of the upper link member 710. This arrangement allows the guide pin 754 and pin support 752 to travel in a constrained and predefined manner defined by the first keyway 920. The second keyway 922 receives the guide pin 654 of the lower link member 610, and the lower slit 930 receives the lower pin support 652. This arrangement allows the guide pin 654 and pin support 652 to travel in a constrained and predefined manner defined by the second keyway 922.

[0176] Note that the guide pin 654 and / or pin support 652 of the lower link component 610 represent a key arrangement configured to engage and slide within the keyway 922 when the lower chain assembly (of the series of lower link components 610) is decoupled from the upper chain assembly (of the series of upper link components 710). Similarly, the guide pin 754 and / or pin support 752 of the upper link component 710 represent another key arrangement configured to engage and slide within the keyway 920 when the upper chain assembly is decoupled from the lower chain assembly. When the upper and lower chain assemblies are coupled together, both key arrangements engage and slide within the keyway 924. See, for example, [link to relevant documentation]. Figure 78 and Figure 79 In this way, guide pin 654 cooperates with keyway 922 to hold at least a portion of the lower component 602 on guide rail 910 in a retracted state. Similarly, guide pin 754 cooperates with keyway 920 to hold at least a portion of the upper component 702 on guide rail 910 in a retracted state.

[0177] Guide rail 910 has a main longitudinal axis 936, which is generally defined by a line centered within the internal space of guide rail 910 (see...). Figure 73 The diagram shows the longitudinal axis 936 for entering and exiting the guide rail 910. In some exemplary embodiments, the guide rail 910 employs a curved main longitudinal axis 936 that accommodates the folded storage of the upper and lower chain assemblies when the protrusion structures 744, 644 are decoupled from each other, and thus accommodates the folded storage of the corresponding lower and upper assemblies 602, 702. Figures 73-79 Only the transition area of ​​guide rail 910 is shown, which has a curved shape. Although in Figure 71 The guide rail 910 is not depicted, but the curved shape of the retracted and folded portions of the support mechanism 900 is clearly shown. For Figure 71In the implementation shown, the guide rail 910 is bent in an appropriate manner, forcing the upper and lower components 702, 602 to follow the bending path shown. In some embodiments, when the support mechanism 900 is in the retracted state, the guide rail arrangement, one or more individual guide rails 910, and / or another guiding or storage feature can be used to receive, guide, and retract a portion of the flexible working surface component 860.

[0178] Guide rail 910 includes a curved gooseneck region 940, which serves as a transition for coupling / decoupling lower and upper components 602, 702. For the depicted embodiment, the curved gooseneck region 940 accommodates the desired predefined hump shape of the first keyway 920 (see [link to embodiment]). Figure 75 This is necessary for raising and lowering the upper component 702 relative to the lower component 602 during the coordinated movement of the components. (See reference) Figure 76 and Figure 77 The humped shape of the first keyway 920 ensures that the upper link component 710 properly mates with the lower link component 610 in the appropriate position during deployment. Keyways 920 and 922 can be brought closer together below the curved gooseneck region 940 while maintaining the desired separation between the lower and upper components 602 and 702 (see...). Figure 75 The curved gooseneck region 940 enables the lower and upper components 602, 702 to transition from a decoupled state to a coupled state (and vice versa) in response to coordinated movement during deployment and retraction, as referenced above. Figure 76 and Figure 77 As explained, the shape of the curved gooseneck region 940 and the variable spacing between the first and second keyways 920, 922 push the lower and upper components 602, 702 into the desired position as they move collaboratively during extension and retraction.

[0179] As referenced above Figure 1 and Figure 2 The load-bearing support structure utilizing the support mechanism 900, as described, may include storage units, either wholly or partially, arranged around the guide rail 910. The storage units are shaped and sized to accommodate the retraction of the deformable support mechanism 900 (including the chain assembly, upper and lower assemblies 702, 602, etc.) in the retracted state. Furthermore, the storage units may include openings defined or formed therein, which are shaped and sized to accommodate the passage of the deformable support mechanism 900 when the upper and lower assemblies 702, 602 are coupled together in the deployed state.

[0180] Supplementary or optional features

[0181] Various embodiments of the present invention, including the first and second embodiments described above, can implement certain features, functions, and / or structures suitable for a particular application or use case. This section describes several supplementary or optional features.

[0182] Curved support surface—The first and second embodiments described above employ relatively flat and straight support structures (once deployed). In this respect, the first and second embodiments are suitable for use as tabletops, desk surfaces, walls, pocketdoors, armrests, seat trays, etc. According to alternative embodiments, the deformable support mechanism can be suitably configured to provide a curved or angled (non-flat, non-planar) support surface when deployed. To achieve a non-planar support surface, the upper and lower components can be configured asymmetrically. For example, the upper link component can be longer or shorter than the corresponding lower link component, resulting in a curved or bent arrangement after the upper and lower components are coupled together.

[0183] Deployment Options—Depending on certain implementations, the deformable support mechanism can be manually deployed to a desired position and manually returned to its original retracted position. For example, the leading edge assembly may include a handle, a recess or hole for accommodating a user's hand or fingers, or a tab that can be used to pull / push the support mechanism as needed. In some embodiments, movement of the support mechanism may be assisted (e.g., using springs, pneumatic mechanisms, etc.). Alternatively or additionally, the support mechanism may be electronically controlled by a suitably configured motor system.

[0184] Locking Features – The support mechanism is characterized by a fully retracted position and a fully extended position. In some embodiments, the support mechanism may also be positioned in one or more intermediate positions between the fully retracted and fully extended positions. These intermediate positions may be predefined (discrete lockable positions), or the support structure may be appropriately configured such that the support mechanism can be continuously adjusted and locked to any position. For this purpose, the support structure may include one or more locking features or latching mechanisms to hold the support mechanism in place when extended. For example, the support structure may include a manually actuated or electronically activated subsystem that physically restricts the movement of the upper and lower components relative to their respective guide rails, thereby holding them in the desired extended state.

[0185] While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be understood that numerous variations exist. It should also be understood that the one or more exemplary embodiments described herein are not intended to limit the scope, applicability, or configuration of the claimed subject matter in any way. Rather, the foregoing detailed description will provide those skilled in the art with a convenient roadmap for implementing the described embodiments or embodiments. It should be understood that various changes can be made to the function and arrangement of the elements without departing from the scope defined by the claims, which includes equivalents known and foreseeable at the time of filing this patent application.
