METHOD OF STOWING AND DEPLOYING WALL PANELS

Description

BACKGROUND

[0001] The present invention relates to walls that are moveable between a stowed position and a deployed position. US Patent 5,072,766 describes an example of a prior art panel shutter assembly that includes a plurality of shutter panels.

SUMMARY

[0002] In one embodiment, the invention provides a method of moving panels from a stowed position, in which the panels are substantially positioned above a ceiling, to a deployed position, in which the panels are substantially vertically aligned to form a wall. The method includes supporting a first panel having a first weight on a cam, rotating the cam in a first direction and lowering the first panel in response to rotation of the cam. Lowering the first panel separates the first panel from the cam. Supporting the first panel on a flexible lift member in response to lowering the first panel, so that the flexible lift member bears the first weight. Supporting a second panel having a second weight on a support rack, and biasing the second panel into engagement with the cam. The method further includes rotating the cam in the first direction and transferring the second panel from the support rack to the cam in response to rotating the cam, so that the cam bears the second weight. The method further includes further rotating the cam in the first direction, lowering the second panel in response to further rotation of the cam and transferring the second panel from the cam to the first panel, so that the first panel bears the second weight, and the flexible lift member bears the first weight and the second weight through the connection between the first panel and the flexible lift member. The method further includes fixing the second panel to the first panel through a mating tongue and groove engagement.

[0003] In another embodiment, the invention provides a method of moving panels from a deployed position, in which the panels are substantially vertically aligned to form a wall, to a stowed position, in which the panels are substantially positioned above a ceiling. The method includes supporting a first panel having a first weight on a flexible lift member, so that the flexible lift member bears the first weight, supporting a second panel having a second weight on the first panel, so that the flexible lift member bears the first weight and the second weight through the connection between the first panel and the flexible lift member. The method further includes moving the first and second panels substantially vertically and lifting the second panel off of the first panel with a cam, so that the cam bears the second weight, disengaging the second panel from the first panel by vertically displacing the second panel from the first panel. The method further includes transferring the second panel from the cam to a support rack, so that the support rack bears the second weight and displacing the second panel horizontally from the first panel by transferring the second panel onto the support rack. The method further includes further moving the first panel substantially vertically, lifting the first panel with the cam, and rotating the cam so that the cam bears the first weight.

[0004] In still another embodiment, the invention provides a wall panel assembly moveable between a stowed position and a deployed position. The wall panel assembly includes a first wall panel having a first weight and including a first carrier, a flexible lift member coupled to the first wall panel and a second wall panel having a second weight and including a second carrier. A prime mover moves the first and second wall panels between the stowed position and the deployed position. A support rack supports the second carrier and bears the second weight when the second wall panel is in the stowed position, and the flexible lift member bears the second weight when the second wall panel is in the deployed position through the connection between the first wall panel and the flexible lift member. A cam has an exterior perimeter that defines a recess sized to receive at least one of the first and second carriers. The cam rotates in response to the prime mover. Rotation of the cam in a first direction moves the first and second wall panels into the deployed position, and rotation of the cam in a second direction, opposite the first direction, moves the first and second wall panels into the stowed position.

[0005] Other aspects of the invention will become apparent by consideration of the detailed description and accompanying drawings.

[0008] Fig. 1 illustrates a wall panel assembly 10 including a plurality of wall panels 15, a drive assembly 20, first and second jamb assemblies 25a, 25b, and a cable device 30. The illustrated wall panel assembly 10 includes seven separate wall panels 15, but other quantities of wall panels 15 can be utilized. The illustrated plurality of wall panels 15 include a plurality of stowable panels 15s and a bottom panel 15b. The illustrated embodiment includes six stowable panels 15s and one bottom panel 15b.

[0009] A ceiling 35 having an opening 40 is illustrated in phantom in Fig. 1. The wall panel assembly 10 is positioned above the ceiling 35 to substantially hide the wall panel assembly 10 from view when stowed. The wall panels 15 move through the opening 40 to deploy and the illustrated first and second jamb assemblies 25a, 25b extend through the opening 40.

[0010] Fig. 2 illustrates one of the stowable panels 15s in detail. The stowable panels 15s are substantially identical, so the discussion of the stowable panel of Fig. 2 applies to all six of the illustrated stowable panels 15s. The illustrated stowable panel 15s includes a frame 45, front and rear panel faces 50f, 50r, top and bottom dovetail pieces 55t, 55b, carrier mounting brackets 60 and carriers 65. The frame 45 defines top and bottom support brackets 70t, 70b and left and right support brackets 751, 75r. The top and bottom and left and right support brackets 70t, 70b, 751, 75r connect to form the frame 45. The front and rear panel faces 50f, 50r are coupled to the frame 45 to provide first and second oppositely-facing wall surfaces. The illustrated stowable panel 15s is substantially cuboid in shape. The top and bottom dovetail pieces 55t, 55b are mounted on the top and bottom support brackets 70t, 70b, respectively.

[0011] The carrier mounting brackets 60 are coupled to the left and right support brackets 751, 75r, respectively. Fig. 3 illustrates one carrier mounting bracket 60 and one carrier 65 in greater detail. The illustrated carrier mounting bracket 60 includes a hollow tube 80, a first plate 85, a second plate 90, a plurality of fasteners 95 and a carrier retaining sleeve 100. The illustrated hollow tube 80 has a substantially square cross section. The hollow tube 80 and the first plate 85 are positioned on an outside surface of the left support bracket 751 and the second plate 90 is positioned on a inside surface of the right support bracket 75r. The plurality of fasteners 95 extend through respective apertures in the hollow tube 80, the first plate 85, the right support bracket 75r and the second plate 90 to connect the carrier mounting bracket 60 to the frame 45. In the illustrated embodiment, the carrier retaining sleeve 100 is permanently affixed to the hollow tube 85, extends through an aperture in the first plate 85, and abuts the left support bracket 751. The carrier retaining sleeve 100 is hollow and is internally threaded. In the illustrated embodiment, one of the fasteners 95 is positioned above and three of the fasteners 95 are positioned below the carrier retaining sleeve 100. Other quantities, locations and configurations of apertures are possible.

[0012] The carrier 65 includes a fastener 115, a first bearing 120, a snap ring 125, a second bearing 130, a bearing retaining sleeve 135, and a nut 140. The fastener 115 may be a shoulder bolt and includes a head 145 and a shaft 150. The head 145 has a larger diameter than the shaft 150. The illustrated head 145 is round and includes a slot to receive a tool to tighten and loosen the fastener 115. The illustrated shaft 150 includes a threaded portion that is threaded into the carrier retaining sleeve 100. A distance between the head 145 and the carrier retaining sleeve 100 is adjustable by threading or unthreading the fastener 115 from the carrier retaining sleeve 100. The first bearing 120 is positioned on the fastener 115 in abutment with the head 145. The illustrated first bearing 120 is a needle bearing, but another suitable bearing or bushing can be utilized. The snap ring 125 is positioned adjacent the first bearing 120. In the illustrated embodiment, the shaft 150 defines a groove to receive the snap ring 125 therein. The snap ring 125 is operable to retain the first bearing 120 in abutment with the head 145. In another embodiment, a detent or other structural protuberance is utilized the retain the first bearing 120 in abutment with the head 145.

[0013] The second bearing 130 is positioned adjacent the snap ring 125. The illustrated second bearing 130 is a roller bearing, but another suitable bearing or bushing can be utilized. The bearing retaining sleeve 135 is positioned adjacent the second bearing 130. In some embodiments, the bearing retaining sleeve 135 is threaded onto the fastener 115 to retain the second bearing 130 in position on the fastener 115. In the illustrated embodiment, a nut 140 or other structural element is utilized to retain the second bearing 130 in abutment with the snap ring 125. The nut 140 is threaded onto the fastener 115 and is spaced from the bearing retaining sleeve 135 in the illustrated embodiment. The illustrated nut 140 abuts the carrier retaining sleeve 100. The nut 140 permits adjustment of a distance between the head 145 and the carrier retaining sleeve 100. The nut 140 performs the function of a lock nut 230 against the carrier retaining sleeve 100. Other distance adjustment configurations are possible and the illustrated nut 140 and carrier retaining sleeve 100 are given by way of example only.

[0014] With reference to Fig. 4, the bottom panel 15b includes many of the same features as the stowable panels 15s; only the features specific to the bottom panel 15b are discussed herein. The bottom panel 15b includes a bottom seal 155, an object present sensor assembly 160 and a chain mount 165. The seal 155 is coupled directly to the bottom support bracket 70b; the bottom panel 15b has no bottom dovetail piece 55b. The seal 155 is flexible and extends downwardly in a substantially arcuate configuration.

[0015] With reference to Fig. 5, the object presence sensor assembly 160 includes a main body 170, an arm 175, a spring 180 and a circuit element 185. The main body 170 is mounted to the bottom support bracket 70b and extends through an aperture 190 in the bottom support bracket 70b. The arm 175 is coupled to the main body 170 and extends substantially vertically and downward through the aperture 190 in the bottom support bracket 70b. The illustrated arm 175 includes a recess 195 and a pin 200. The illustrated main body 170 abuts the pin 200, and the arm 175 substantially abuts the seal. The spring 180 is coupled to the main body 170 and the arm 175 and retains the arm 175 in a first, un-actuated position. The illustrated circuit element 185 is a switch including a first moveable portion and a second portion. The switch second portion is mounted to the main body 170 and the first moveable portion is free to move with respect to the main body 170. When in the first, un-actuated position, the first moveable portion is spaced from the recess 195. In the second, actuated position, the first moveable portion contacts the recess 195. When actuated, the object presence sensor assembly 160 opens a circuit to stop operation of the drive assembly 20. When the seal 155 abuts an object, such as an obstruction or the floor, the arm 175 is biased upward to actuate the object presence sensor assembly 160 and therefore, stop operation of the drive assembly 20.

[0016] With reference to Fig. 4, the chain mount 165 includes an elongate bracket 205 having an arm, a second bracket 210 and an adjustable connector assembly 215. The elongate bracket 205 is connected to the right support bracket 75r by a plurality of fasteners 220. In another embodiment, the elongate bracket 205 includes an extension that is connected to the bottom support bracket 70b in addition to or in lieu of the elongate bracket 205 being connected to the right support bracket 75r. The arm projects substantially normal to the right support bracket 75r. The arm includes an aperture extending vertically therethrough. The adjustable connector assembly 215 includes an anchor 225, a stud 230, a nut 235 and a lock nut 240. The anchor 225 includes a first aperture oriented along a substantially horizontal axis and a second aperture oriented along a substantially vertical axis. The second aperture 240 is threaded in the illustrated embodiment. The stud 220 is threaded and extends through the arm aperture and into the vertical anchor aperture. The nut 235 and lock nut 240 thread onto the stud 220 below the arm. The nut 235 and lock nut 240 are operable to couple the stud 230 to the arm. A distance between the arm and the anchor 225 is adjustable by adjusting the position of the nut 235 and the lock nut 240 on the stud 230.

[0017] With reference to Fig. 6, the drive assembly 20 includes a prime mover 245, a gear reducer 250, first and second output shafts 255a, 255b and first and second drive box assemblies 260a, 260b. The illustrated prime mover 245 is an electric motor, but in other embodiments, other suitable prime movers can be utilized. The illustrated gear reducer 250 includes one input coupled to the electric motor and first and second outputs 265a, 265b. The first and second outputs 265a, 265b are substantially co-linear and extend outwardly from the gear reducer 250. The first and second output shafts 255a, 255b are coupled to the respective first and second outputs 265a, 265b for rotation therewith. The first and second output shafts 255a, 255b extend toward and engage the respective first and second drive box assemblies 260a, 260b. The illustrated gear reducer 250 also includes a third output 270 (see Fig. 1) extending downward from the gear reducer 250. The third output 270 is engageable by a user for optional manual operation of the gear reducer 250. Although not specifically illustrated, the gear reducer 250 is mounted to the building structure.

[0018] The first and second drive box assemblies 260a, 260b are substantially mirror images, so only the first drive box assembly 260a will be discussed in detail. As shown in greater detail in Figs. 7-9, the first second drive box assembly 260a includes a first drive shaft 275, a first sprocket 280, a second drive shaft 285, a second sprocket 290, a cam 295, a third sprocket 300, a first chain 305, an idler sprocket 310, a flexible lift member 315, a support rack 320 and a bar 322. The first drive shaft 275 is coupled to the first output shaft 255a for rotation therewith. The first sprocket 280 is coupled to the first drive shaft 275 for rotation therewith. The illustrated first sprocket 280 has ten teeth. The second drive shaft 285 is spaced from and substantially parallel to the first drive shaft 275. The second sprocket 290 is coupled to the second drive shaft 285 for rotation therewith. The illustrated second sprocket 290 has sixty teeth. The cam 295 is coupled to the second drive shaft 285 for rotation therewith. The illustrated cam 295 includes a substantially circular outer perimeter defining a first radius and a slot 325 which defines a second radius, smaller than the first radius. The slot 325 is sized to receive one of the carriers 65. The illustrated slot 325 is substantially symmetrical and includes a first substantially planar portion 325a, a second substantially planar portion 325b and a first recess portion 325c between the first and second substantially planar portions. The substantially planar portions 325a, 325b guide the carrier 65 into the recess portion 325c when the cam 295 rotates. The third sprocket 300 is coupled to the second drive shaft 285 for rotation therewith. The illustrated third sprocket 300 is positioned between the second sprocket 290 and the cam 295. The illustrated third sprocket 300 includes thirty teeth and has a one inch pitch.

[0019] The first chain 305 encircles the first sprocket 280 and the second sprocket 290 to couple the first sprocket 280 to the second sprocket 290. The first chain 305 connects the first drive shaft 275 and the second drive shaft 285, such that rotation of the first drive shaft 275 causes rotation of the second drive shaft 285. The idler sprocket 310 is also coupled to the first chain 305 and is utilized to adjust tension in the first chain 305. The first and second sprockets 280, 290 having different quantities of teeth to permit further reduction of rotation of the second drive shaft 285. In the illustrated embodiment, the first sprocket 280 completes six full rotations while the second sprocket 290 completes only one full rotation. Other quantities of teeth and varieties of gear reduction are possible, and the illustrated is given by way of example only.

[0020] The illustrated flexible lift member 315 is a length of chain (herein referred to as a second chain) but other flexible lift members, such as cables, ropes, cords, strings, and the like can be utilized in place of the illustrated second chain 315. The second chain 315 engages the third sprocket 300 and thereby moves in response to rotation of the second drive shaft 285. The second chain 315 is coupled to the bottom panel 15b via the adjustable connector assembly 215. Specifically, a cross link member of the second chain 315 extends through the first aperture 235 of the anchor 215.

[0021] The illustrated support rack 320 is a vertically extending plate with an inclined upper edge. The inclined upper edge is sized to support the carriers 65. In the illustrated embodiment, the carrier second bearing 130 moves along the inclined upper edge. The inclined edge of the support rack 320 is angled downwardly toward the cam 295. Gravity is utilized to move the carriers 65 into engagement with the cam 295. In another embodiment, a separate motive force (in addition to gravity) is utilized to move the carriers 65 into engagement with the cam 295. In the illustrated embodiment, the incline is about 5 degrees, but other incline angles can be utilized. The bar 322 illustrated in Fig. 8 is positioned above the inclined support rack 320 and inhibits the carriers 65 from detaching from the inclined support rack 320. The bar 322 can assist in aligning the stowable panels 15s on the inclined support rack 320. The bar 322 is only illustrated in Fig. 8, but is omitted from the remaining figures for clarity.

[0022] With reference to Fig. 10, the first jamb assembly 25a includes an external housing assembly 330 and an internal guidance system 335. The first jamb assembly 25a and the second jamb assembly 25b are substantial mirror images, so only the first jamb assembly 25a is described in detail. The external housing assembly 330 is mounted to a floor and the first drive box assembly 260a and includes first and second L-shaped brackets 340a, 340b, first and second mounting brackets 345a, 345b, first and second gaskets 350a, 350b and first and second alignment brackets 352, 353. The first and second L-shaped brackets 340a, 340b define a structure substantially enclosed on three sides, thereby leaving one side substantially open. The illustrated first and second L-shaped brackets 340a, 340b are jamb receivers made from extruded aluminum. The illustrated first and second mounting brackets 345a, 345b are guide rails that extend across a portion of the open side. The first and second mounting brackets 345a, 345b extend inward into an interior of the structure. The first and second gaskets 350a, 350b extend inward from the first and second mounting brackets 345a, 345b across a portion of the open side. The first and second alignment brackets 352, 353 (see Fig. 8) engage and vertically align the panels 15 during stowage and deployment. The illustrated alignment brackets 352, 353 are shown by way of example only. Other configurations, shapes and quantities of alignment brackets can be utilized. In some embodiments, the alignment brackets are omitted. The external housing assembly 330 receives the second chain 315 extending therethrough. In some embodiments, the first jamb assembly 25a is mounted to a building wall and the external housing assembly 330 extends into a room in the building. In other embodiments, the first jamb assembly 25a is mounted to a building wall and the external housing assembly 330 is contained within the wall.

[0023] The internal guidance system 335 includes first and second guide brackets 355a, 355b coupled to respective first and second mounting brackets 345a, 345b. The first and second guide brackets 355a, 355b define a substantially vertical opening 40 sized to received the carriers 65 therein. The first and second guide brackets 355a, 355b substantially surround a portion of the carriers 65 to retain the panels in a substantially aligned orientation.

[0024] The cable device 30 (shown in Fig. 1) is a centrifugal cam 295 including a housing 360 and a cable 365. Although not specifically shown, one cable device 30 can be provided per drive box assembly 260a, 260b. The cable 365 is free to move with respect to the housing 360 at low speed, but the cable device 30 brakes at high speed. The housing 360 is coupled to the building or other structure and the cable 365 is coupled to the bottom panel 15b. In the event that the any component in the wall panel assembly 10 fails, the cable device(s) 30 support the bottom panel 15b, and thus, the remaining panels resting on the bottom panel 15b.

[0025] In operation, the panels 15b, 15s are moved between a stowed position (shown in Fig. 11) to a deployed position (shown in Fig. 18). Figs. 12-17 illustrate some of the steps of deploying the panels 15b, 15s and Figs. 19-22 illustrate some of the steps of stowing the panels 15b, 15s.

[0026] In a stowed position, the stowable panels 15s are supported on the support racks 320 via the carriers 65. The support racks 320 bear the weight of the stowable panels 15s in the illustrated stowed position. The support racks 320 are inclined to bias the stowable panels 15s into engagement with the cams 295. In the illustrated stowed position, the bottom panel 15b is supported on the cams 295 via the carriers 65 in the slots 325. In the illustrated stowed position, the cams 295 bear the weight of the bottom panel 15b and the chains 315 bear little or none of the weight of the bottom panel 15b. In another embodiment, the bottom panel 15b is supported by the chains 315 in the stowed position. In still another embodiment, the bottom panel 15b is supported by the support racks 320 in the stowed position. In the stowed position, the bottom panel 15b is recessed above the ceiling 35 so that the seal 155 is recessed above the ceiling 35. In another embodiment, the seal 155 is level with the ceiling 35 when the wall panels 15 are stowed.

[0027] Operation of the motor 245 rotates the first and second outputs 265a, 265b of the gear reducer 250. The first and second outputs 265a, 265b of the gear reducer 250 cause rotation of the respective first and second output shafts 255a, 255b. The first and second output shafts 255a, 255b rotate respective first drive shafts 275, which thereby rotate the respective first sprockets 280. Rotation of the first sprockets 280 causes movement of the respective first chains 305, which causes rotation of the respective second sprockets 290 and thereby, rotation of the respective second drive shafts 285. The cams 295 and the third sprockets 300 are coupled for rotation with the respective second drive shafts 285. Therefore, the cams 295 rotate about the respective second drive shafts 285 in response to operation of the motor 245.

[0028] To deploy the wall panels 15, the motor 245 causes the cams 295 to rotate to release the carriers 65 of the bottom panel 15b from the cam slots 325, to thereby lower the bottom panel 15b (see Fig. 12). When released from the cam slots 325, the chains 315 bear the weight of the bottom panel 15b through the chain mounts 165. As the second drive shafts 285 continue to rotate, the chains 315 continue to lower the bottom panel 15b. The first and second alignment brackets 352, 353 guide the bottom panel 15b to maintain the bottom panel 15b in a substantially vertical orientation.

[0029] As shown in Fig. 13, the inclined support racks 320 bias the carriers 65 of the first stowable panel 15s against the respective cams 295. The carriers 65 abut the cams 295 as the cams 295 rotate in response to rotation of the second drive shafts 285. In the illustrated embodiment, the second bearings 125 ride along the outside surface of the cams 295. When the cam 295 slots are oriented to receive the carriers 65 of the first stowable panel 15s, the inclined support racks 320 bias the carriers 65 of the first stowable panel 15s into the cam slots 325 (see Fig. 14). The carriers 65 ride along the inclined support racks 320 into the recess portions 325c.

[0030] With reference to Fig. 15, the cams 295 lift the first stowable panel 15s off of the inclined support racks 320, thereby transferring the weight of the first stowable panel 15s from the support racks 320 to the cams 295. In the illustrated embodiment, the cams 295 engage the first bearings 120 of the carriers 65. The recess portions 325c retain the carriers 65 until the cams 295 have rotated to a position in which the slots 325 are facing substantially horizontal, such as the position illustrated in Fig. 16.

[0031] In the illustrated embodiment, the recess portions 325c are sized to receive the carriers 65. In other embodiments, the recess portions 325c are larger than the carriers 65 and permit the carriers 65 to slide along the recess portions 325c. In these embodiments, the carriers 65 roll along the slots 325 when the slots are facing substantially vertically upward. The recess portions 325c define a length which is adjustable to accommodate tolerance requirements and to minimize noise when the carriers 65 move along and abut ends of the recess portions 325c.

[0032] As shown in Fig. 16, the cams 295 continue to rotate in response to operation of the motor 245 to position the first stowable panel 15s substantially vertically above the bottom panel 15b. The first and second alignment brackets 352, 353 guide the first stowable panel 15s into vertically alignment with the bottom panel 15b. The cams 295 continue to lower the first stowable panel 15s onto the bottom panel 15b, such that the mating dovetail pieces 55t, 55b on a top of the bottom panel 15b and on a bottom of the first stowable panel 15s engage. As shown in Fig. 17, the cams 295 release the first stowable panel 15s and the chains 315 support the first stowable panel 15s in response to the connection between the first bottom panel 15b and the chains 315. The first stowable panel 15s is not connected to the chains 315, except for the indirect connection through the first bottom panel 15b.

[0033] With continued reference to Fig. 17, the first and second jamb assemblies 25a, 25b, specifically the first and second alignment brackets 352, 353, orient the first stowable panel 15s above the bottom panel 15b to guide the dovetails 55t, 55b into mating engagement when the cams 295 release the first stowable panel 15s. The first and second jamb assemblies 25a, 25b are fixed to the respective first and second drive box assemblies 260a, 260b and to the floor. The first and second alignment brackets 352, 353 guide and vertically align the panels 15b, 15s during deployment and stowage. The carriers 65 move within the internal guidance system 335 of the first and second jamb assemblies 25a, 25b.

[0034] The remaining stowable panels 15s are deployed in the same manor as the first stowable panel 15s is deployed. The stowable panels 15s rest on top of other stowable panels 15s and the bottom panel 15b when deployed. The top dovetail piece 55t of one panel mates with the bottom dovetail piece 55b of the panel above it, when the wall panel assembly 10 is deployed. The chains 315 bear the weight of all of the deployed panels 15 via the connection between the chains 315 and the bottom panel 15b. Fig. 18 is a perspective view of the panels 15b, 15s in a deployed position in which all of the stowable panels 15s are positioned on the bottom panel 15b. In the illustrated embodiment, the top panel 15s extends through the opening 40 above the ceiling 35. In another embodiment, a top of the top panel 15s is substantially level with the opening 40. The mating dovetail pieces 55t, 55b of the stowable panels 15s engage to substantially fix the adjacent deployed panels 15b, 15s together. The weight of the stowable panels 15s, the mating dovetail pieces 55t, 55b and the first and second jamb assemblies 25a, 25b, in combination, retain the wall panels 15 in a substantially vertical position when deployed. The front and rear panel faces 50f, 50r of the wall panels 15 together provide a substantially continuous wall surface when the wall panel assembly 10 is deployed.

[0035] To stow the panels 15, the motor 245 operates in an opposite direction of that of deployment. Operation of the motor 245 rotates the cams 295 in the opposite direction. With reference to Fig. 19, the cams 295 engage the carriers 65 of the top panel 15s. In response to rotation of the cams 295, the cams 295 lift the top panel 15s off of the other panels 15s, 15b, as shown in Fig. 20. The top panel 15s is first vertically displaced from the remaining panels 15s, 15b in response to rotation of the cams 295. The top panel 15s is then horizontally displaces from the remaining panels 15s, 15b in response to further rotation of the cams 295, as shown in Fig. 21.

[0036] Fig. 21 also illustrates that the chains 315 continue to lift the remaining panels 15s, 15b as the cams 295 transfer the top panel 15s onto the inclined support rack 320. The top panel 15s is urged up the inclined support rack 320 by the second substantially planar portion 325a. As shown in Fig. 22, the chains 315 further lift the remaining panels 15s, 15b as the cam 295 slots approach the carriers 65 of the next panel. In the illustrated embodiment, one full rotation of the cam 295 occurs per stowing or deploying of one panel 15. The illustrated third sprocket 300 has an outside perimeter that equals the height of the panels 15. The illustrated cams 295 have a larger diameter than the third sprockets 300 so that the cams 295 lift the panel 15s off of the remaining panels 15s, 15b while stowing and lowers the panel 15s vertically onto the remaining panels 15s, 15b while deploying. This lifting and lowering permits vertical alignment of the mating dovetail protrusions 55t, 55b prior to mating engagement of the mating dovetail protrusions 55t, 55b.
