DETAILED DESCRIPTION
[0014] FIG.
1 shows a portion of a vehicle 10 with a slidable room 20 in an extended po-sition. During movement or transport of the vehicle, the slidable room 20 is normally fully re-tracted into the vehicle 10. The vehicle wall 13 has an opening 12 into which the slidable room 20 fits. Positioned about the edges of the opening 12 is a frame 14. As shown in FIGS. 2 and 2A, frame 14 consists of two cable frames 15 and two interconnecting frames 17, 19. In the em-bodiments shown in the figures, the cable frames 15 are jambs and the interconnecting frames are a header 17 and sill 19. Preferably, one or more rollers 16 are attached to sill 19 and room 20 rolls on these rollers 16 when room 20 is extended or retracted. Optionally, seals, such as a polymeric strip, can be provided on the inside of frame 14 to provide a weather tight seal be-tween the frame and the room 20. Room 20 can include a dinette, wardrobe, library, storage, bedroom, closet, kitchen, etc. compartment.
[0015] The vehicle 10 may be a self-powered vehicle, such as a recreational vehicle, or may be a trailer that is adapted to be towed, e.g., by an automobile or a truck tractor. The vehicle may be one that is designed for living (as a house trailer), or may be a work vehicle (e.g., a mo-bile library). The slidable room 20 can also be used with fixed structures such as modular hous-ing or vacation homes.
[0016] As shown in FIGS. 3 and 4A, each cable frame or jamb 15 is pre-assembled with a plurality of pulleys 46 and a plurality of cables 40 pre-strung around the pulleys 46. One end 41 of each cable 40 extends from a pulley 46 through a cable extension hole 36 in jamb 15. Af-ter installation, the cable first ends 41 are attached to room 20 with attachment anchors 30. Pref-erably, a cable end plug 43 is attached to the cable first ends 41 to prevent the ends of the cables from being pulled through the cable extension holes 36.
[0017] The other end or second end 42 of each cable 40 extends from an end of jamb 15.
After installation, the cable second ends 42 are attached a drive motor 24.
Preferably, each jamb 15 includes four cables 40. The cable second ends 42 are strung through a comer pulley bracket 32, which includes two double pulleys 33. After passing through a comer pulley bracket 32, the cable second ends 42 are attached to a chain 26 by cable chain connectors 28.
Chain 26 is then attached to a sprocket 34 on drive motor 24. Each end of chain 26 is attached by a cable chain connector 28 to two cable second ends 42. The cables 40 attached to one end of chain 26 are at-
-5-tached to the outside 20b of 'room 20 and the cables 40 attached to other end of chain 26 are at-tached to the inside 20a of room 20. Since frame 14 includes two jambs 15, two chains 26 are attached to sprockets 34 on drive motor 24. Each chain 26 connects to the cables 40 associated with one jamb 15. Therefore, each chain 26 is associated with one side of room 20, either the left side or the right side.
[0018] FIG. 2C illustrates the drive motor 24 according to one or more embodiments.
Here, the drive motor 24 includes an electric motor 102 that is operatively connected to the sprocket 34 to cause the sprocket 34 to rotate clockwise or counter clockwise.
Alternatively, however, the drive motor 24 may comprise a portable motor or hand crank, (not illustrated) that is connected to sprocket 34 when the room 20 is to be moved. Whatever folin of power input is used, the room 20 may be locked in place when it is not in motion. Here, the drive motor 24 includes a worm gear 104 that performs a locking function when the room 20 is at rest, locking the room 20 in place (in closed position when fully retracted, for example).
With other drive mechanisms, locking means as known in the art may be utilized. In addition to changing the axis of rotation, the worm gear 104 also acts as a locking device to hold the room 100 in either the extended position (shown in FIG. 1) or the retracted position (not illustrated). If a womi gear is not used, another mechanism for locking the room 20 in either the extended or retracted positions. Also illustrated in FIG. 2C, the drive motor 24 includes a hex shaped adapter 106 operatively connected to and extending from the electric motor 102 to permit manual rotation of the drive motor 24, for example, via a socket wrench. This permits the room 20 to be extended or retracted manually in the event power is not available for the electric motor 102.
[0019] When drive motor 24 is rotated in a first direction, the cables 40 attached to the inside 20a of room 20 are retracted, causing room 20 to be extended out of vehicle 10. When drive motor 24 is rotated in the opposite direction, the cables 40 attached to the outside 20b of room 20 are retracted, causing room 20 to be retracted into vehicle 10.
[0020] As shown in FIGS. 3, 4A, 4C, 4D and 5, the preferred embodiment of jamb 15 has two sets of double pulleys 46, a lower set and an upper set. The upper set of double pulleys 46 also includes an idler 48. Pulley support brackets 55a, 55b are riveted to jamb 15. The pulleys 46 and idler 48 are all attached to jamb 15 by clevis pins 56 that fit through holes in jamb 15 and pulley support brackets 55a, 55b. A clip (not shown) fits into a hole in clevis pin 56 to retain clevis pin 56 in the pulley support brackets 55a, 55b.
[0018] FIG. 2C illustrates the drive motor 24 according to one or more embodiments.
Here, the drive motor 24 includes an electric motor 102 that is operatively connected to the sprocket 34 to cause the sprocket 34 to rotate clockwise or counter clockwise.
Alternatively, however, the drive motor 24 may comprise a portable motor or hand crank, (not illustrated) that is connected to sprocket 34 when the room 20 is to be moved. Whatever folin of power input is used, the room 20 may be locked in place when it is not in motion. Here, the drive motor 24 includes a worm gear 104 that performs a locking function when the room 20 is at rest, locking the room 20 in place (in closed position when fully retracted, for example).
With other drive mechanisms, locking means as known in the art may be utilized. In addition to changing the axis of rotation, the worm gear 104 also acts as a locking device to hold the room 100 in either the extended position (shown in FIG. 1) or the retracted position (not illustrated). If a womi gear is not used, another mechanism for locking the room 20 in either the extended or retracted positions. Also illustrated in FIG. 2C, the drive motor 24 includes a hex shaped adapter 106 operatively connected to and extending from the electric motor 102 to permit manual rotation of the drive motor 24, for example, via a socket wrench. This permits the room 20 to be extended or retracted manually in the event power is not available for the electric motor 102.
[0019] When drive motor 24 is rotated in a first direction, the cables 40 attached to the inside 20a of room 20 are retracted, causing room 20 to be extended out of vehicle 10. When drive motor 24 is rotated in the opposite direction, the cables 40 attached to the outside 20b of room 20 are retracted, causing room 20 to be retracted into vehicle 10.
[0020] As shown in FIGS. 3, 4A, 4C, 4D and 5, the preferred embodiment of jamb 15 has two sets of double pulleys 46, a lower set and an upper set. The upper set of double pulleys 46 also includes an idler 48. Pulley support brackets 55a, 55b are riveted to jamb 15. The pulleys 46 and idler 48 are all attached to jamb 15 by clevis pins 56 that fit through holes in jamb 15 and pulley support brackets 55a, 55b. A clip (not shown) fits into a hole in clevis pin 56 to retain clevis pin 56 in the pulley support brackets 55a, 55b.
- 6 -[0021] As shown iri 'figures 3 and 4A, one cable 40 extends from a first cable chain connector 28, through corner pulley bracket 32, around an upper pulley 46, through an upper cable extension hole 36 and is then attached to the outside 20b of room 20. A
second cable 40 extends from the first cable chain connector 28, through corner pulley bracket 32, around a lower pulley 46, through a lower cable extension hole 36 and is then attached to the outside 20b of room 20. A third cable 40 extends from a second cable chain connector 28, through corner pulley bracket 32, around idler 48, an upper pulley 46, through an upper cable extension hole 36 and is then attached to the inside 20a of room 20. The fourth cable 40 extends from the second cable chain connector 28, through corner pulley bracket 32, around a lower pulley 46, through a lower cable extension hole 36 and is then attached to the inside 20a of room 20. Since there are two jambs 15, this cable arrangement is repeated for the other side of the room 20.
[0022] Although the preferred embodiment shown in the figures shows the cable frames or jambs 15 on the sides of room 20 with the interconnecting frames 17, 19 forming the header 17 and sill 19 of frame 14, the cable frames 15 could be positioned above and below room 20 with the interconnecting frames 17, 19 along the sides of room 20. The motor 24, along with the corner pulley brackets 32, would preferably then be positioned along one of the sides of room 20.
It is also possible to use more or less cables in each jamb 15 than the four cables shown in the figures. The second ends 42 of cables 40 could exit the lower end of jamb 15 with corner pulley brackets 32 and motor 24 being mounted below room 20. The first ends 41 of cables could alternatively be attached to the top and bottom of room 20, rather than to the sides of room 20.
[0023] Cable frame or jamb 15 preferably includes a cap or jamb clamp 60 (See FIG. 5).
The jamb 15 has an attachment flange 54 that is attached to the outside of vehicle wall 13. The inside portion of jamb 15 has a jamb slot 66 into which the jamb clamp 60 fits. The jamb clamp 60 includes an attachment flange 62 that is parallel to the jamb attachment flange 54 and is attached to the inside of vehicle wall 13. The jamb clamp 60 also has a hook 64 that fits into jamb slot 66. During installation of jamb 15, jamb 15 with the attached pulleys 46 and pre-strung cables 40 is attached to vehicle wall 13 using a plurality of fasteners (not shown). Then the jamb clamp hook 64 is inserted at an angle into the jamb slot 66. Finally, jamb clamp 60 is rotated so that the attachment flange 62 fits against vehicle wall and is attached to the inside of vehicle wall 13 with a plurality of fasteners (not shown). Sill 19 preferably has the same shape as jamb 15. A
sill clamp 21, also preferably having the same shape as jamb clamp 60, fits into sill 19. Sill 19
second cable 40 extends from the first cable chain connector 28, through corner pulley bracket 32, around a lower pulley 46, through a lower cable extension hole 36 and is then attached to the outside 20b of room 20. A third cable 40 extends from a second cable chain connector 28, through corner pulley bracket 32, around idler 48, an upper pulley 46, through an upper cable extension hole 36 and is then attached to the inside 20a of room 20. The fourth cable 40 extends from the second cable chain connector 28, through corner pulley bracket 32, around a lower pulley 46, through a lower cable extension hole 36 and is then attached to the inside 20a of room 20. Since there are two jambs 15, this cable arrangement is repeated for the other side of the room 20.
[0022] Although the preferred embodiment shown in the figures shows the cable frames or jambs 15 on the sides of room 20 with the interconnecting frames 17, 19 forming the header 17 and sill 19 of frame 14, the cable frames 15 could be positioned above and below room 20 with the interconnecting frames 17, 19 along the sides of room 20. The motor 24, along with the corner pulley brackets 32, would preferably then be positioned along one of the sides of room 20.
It is also possible to use more or less cables in each jamb 15 than the four cables shown in the figures. The second ends 42 of cables 40 could exit the lower end of jamb 15 with corner pulley brackets 32 and motor 24 being mounted below room 20. The first ends 41 of cables could alternatively be attached to the top and bottom of room 20, rather than to the sides of room 20.
