DETAILED DESCRIPTION
Referring now to the drawings, a truck 10 having a collapsible shell 12, 112 is shown. The collapsible shell 12, 112 may be traversed to a stored position, as shown in FIGS. 1 and 7 which allows the user to have full access a bed 14 of the truck. The collapsible shell 12, 112 may also be traversed to an extended position, as shown in FIGS. 6 and 14 which provides for a protected interior volume under a cover 16, 116 at the truck bed 14. In this manner, the collapsible shell 12, 112 provides for either full access to the truck bed when the collapsible shell 12, 112 is in the collapsed or stored position or when needed an interior protected volume at the truck bed 14 so that utility of the truck bed 14 is not diminished when the collapsible shell 12, 112 is mounted to the truck 10. The user can load a full-sized motorcycle on top of the truck bed 14 when the collapsible shell 12, 112 is in the collapsed or stored position. When needed, the user can also traverse the collapsible shell 12, 112 to the extended or erected position when needed in order to create the interior protected volume at the truck bed 14 to store things.
The collapsible shell 12, 112 is discussed herein in relation to the truck 10 having the truck bed 14. However, it is also contemplated that the collapsible shell 12, 112 may also be mounted to any type of vehicle having a cargo area with an open top area. By way of example and not limitation, the collapsible shell 12, 112 may also be mounted to a golf cart having an open cargo area or container behind the passenger area. Additionally, the collapsible shell 12, 112 may be mounted to a container having an open top.
The truck 10 may define a cab 18 having a roof 20. The truck bed 14 may define first and second sidewalls 22, 24 which are positioned on opposite sides of a floor 26 of the truck bed 14. As discussed above, the collapsible shell 12, 112 may be mounted to other types of vehicle as well as to a container. In this regard, opposed walls of the container would be the functional equivalent of the first and second sidewalls 22, 24 of the truck bed 14.
Referring now to FIGS. 1-6, a first embodiment of the collapsible shell 12 is shown. The second embodiment of the collapsible shell 112 shown in FIGS. 7-14 is identical to the first embodiment of the collapsible shell 12 shown in FIGS. 1-6 except as described further below. The collapsible shell 12 may have a plurality of first frames 28a-n and a plurality of second frames 30a-n. The first and second frames 28a-c, 30a-c may be slidably mounted to the first and second sidewalls 22, 24 of the truck bed 14. The plurality of first frames may be slidably mounted to the first sidewall 22 by installing a sliding track 32 on an upper edge or surface of the first sidewall 22. Similarly, the plurality of second frames may be slidably mounted to the second sidewall 24 by installing a sliding track 34 on an upper edge or surface of the second sidewall 24. Followers may be mounted to a bottom side of the frames 28, 30 wherein the followers slidably engaged the first and second sliding tracks 32, 34. The followers and sliding tracks 32, 34 allow the first and second frames 28, 30 to slide between a collapsed position and an extended position.
FIG. 3 illustrates the plurality of first and second frames 28, 30 when the frames 28, 30 are in the fully extended position. The first frames 28b, 28c may be slidably mounted to the first sidewall 22 while the first frame 28a may be rigidly secured to the first sidewall 22 or sliding track 32. Similarly, the second frames 30b, 30c may be slidably mounted to the second sidewall 24 while the second frame 30a may be rigidly secured to the second sidewall 24 or sliding track 34. Front portions 36, 38 of the frames 28a, 30a may be attached to the cab 18 in a manner that allows for some flex. As the truck 10 moves over uneven terrain, the cab 18 may move independent from the truck bed 14. By attaching the frames 28a, 30a to the cab 18 to allow for some flex, movement of the cab 18 does not transfer any undue force to the truck bed 14 and movement of the truck bed 14 does not transfer any undue force to the cab 18 so that usage of the collapsible shell 12 does not compromise the structural integrity of the truck bed 14, the cab 18 and the shell 12.
The sliding track 32, 34 may each have two races. The first race of the sliding track 32 may receive the follower attached to the first frame 28b. The second race of the sliding track 32 may receive the follower attached to the first frame 28c. The first race of the sliding track 34 may receive the follower attached to the second frame 30b. The second race of the sliding track 34 may receive the follower attached to the second frame 30c. The frames 28a and 30a may be fixedly secured to the first and second sidewall 22, 24. The follower may be a tongue and the first and second races of the first sliding track 32 may be grooves that receive the follower. Alternatively, the follower and the first and second races may have a ball bearing engagement between the two so that the weight of the frames 28b, c, 30b, c does not hinder sliding movement of the frames 28b, c, 30b, c along the first and second sliding tracks 32, 34. Optionally, the first and second frames 28a, 30a may be slidably attached to the first and second sidewalls 22, 24 by providing for an additional race in the first and second sliding tracks 32, 34 that receive followers that are attached to the first and second frames 28a, 30a. The followers may be secured to the bottom side of the frames 28, 30. The races may be parallel to each other.
Alternatively, the first frames 28b, 28c may be slidably attached to the first frames 28a, 28b. Similarly, the second frames 30b, c may be slidably attached to the second frames 30a, b. The slidable attachment between the respective first and second frames 28a, b, c and 30a, b, c may be achieved through a tongue and groove connection between the first frames 28b to 28a and 28c to 28b as well as between the second frames 30b to 30a and 30c to 30b. When the first and second frames 28, 30 are in the extended position, as shown in FIG. 3, the first and second frames 28, 30 may be locked to the extended position.
The frames 28, 30 may each be fabricated from a rigid tubular material. In the drawings, the rigid tubular material has an L-shape. However, it is also contemplated the rigid tubular material may be rectangularly shaped. The L-shaped tubular material may also have a generally rigid panel 31 which may be opaque, transparent or translucent. The followers may be attached to the bottom sides of the rigid panel for mounting to the sliding tracks 32, 34. If the frames 28, 30 are rectangularly shaped tubular material, then the followers may be attached to the bottom sides of the rigid tubular material of the bottom side thereof.
Other materials for the frame 28, 30 may also be utilized including but not limited to fiberglass, carbon fiber, aluminum or solid bar. The frame 28, 30 may be fabricated from a material that can withstand wind and driving forces due to the truck 10 driving on the freeway at speeds of up to 65-90 mph and cornering.
The frames 28, 30 may collapse and extend along the sidewalls 22, 24 of the truck bed 14. However, the frames 28, 30 may not provide any protection on the top of the shell 12, 112. Rather, the frames 28, 30 only protect the sides of the collapsible shell 12, 112. To this end, the collapsible shell 12, 112 may further have a cover 16 that can be secured to the frames 28, 30 when the frames 28, 30 are telescoped out to the extended position (see FIG. 4). The cover 16 may start from a stored position collapsed over the cab 18 of the truck 10. When the cover 16 is in the stored position, a fairing 40 may shield the cover 16 so that as the truck 10 moves forward, oncoming wind flows over the cover 16 and the cover 16 does not add to the wind resistance of the truck 10. Moreover, the fairing 40 mitigates the possibility that wind will pick the cover 16 up inadvertently when the cover 16 stored position and rip the cover 16 off of the roof of the cab.
Although the frames 28, 30 are shown as having an open top when the frames 28, 30 are in the extended position it is also contemplated that the frames 28, 30 may extended inward or medially at the top so as to provide protection to the top side of the shell 12, 112. The medial sides of the extended portions of the frames 28, 30 may join together and provide for a watertight seal.
The cover 16 may comprise a plurality of panels that can be stacked upon each other in an accordion fashion. This is shown in FIGS. 5 and 6. Four panels 42a-d may make up the cover 16. Although only four panels 42a-d is shown as making up the cover 16, it is also contemplated that the cover may be fabricated from one or more panels 42. If it is only a single panel, then the panel 42 would cover only the topside of the shell 12 but not the backside of the collapsible shell 12, 112. Moreover, the cover 16 is shown as being a plurality of rigid panels that are stacked in an accordion fashion. However it is also contemplated that the cover 16 may be fabricated from a flexible material that can be rolled up and disposed under the fairing 40 then unrolled in order to protect or form an enclosure over the truck bed 14 in conjunction with the frames 28, 30. The flex cover 16 would also be capable of being unrolled to cover the back side of the shell 12.
The cover 16 may be sufficiently wide in order to engage the topsides of the frames 28, 30. More particularly, the cover 16 may form a seal along the topsides of the frames 28, 30 wherein the seal may be watertight to provide a dry interior volume over the truck bed 14. The cover 16 may have a rubber seal along the outer peripheral edges that engage the frames 28, 30 to form that watertight seal. The cover 16 may be secured to the frames 28, 30 with latches including but not limited to rubber latches or mechanically operated latches.
To deploy the cover, the fairing 40 which may be pivotally attached to the roof 20 of the cab 18 may be pivoted upward as shown in FIG. 3. The fairing 40 may be held in the upward position by a spring. The fairing 40 may also be held in the down position or stored position with the latch to resist the upward spring motion. The latch may be attachable to the shield and the roof of the cab and be detachable in order to traverse the fairing 40 to the upward position. By pivoting the fairing 40 upward, this provides room or allows the cover 16 to be unfolded over the truck bed as shown in FIGS. 5 and 6. The fairing 40 may be placed back to the down position, as shown in FIGS. 5 and 6 and locked into place with a lock. The cover 16 may also be secured to the frames 28, 30 with a locking mechanism 44. A plurality of locking mechanism 44 may be disposed along the length of the frames 28, 30 so as to engage the frames 28, 30 and the cover 16 to each other.
The frames 28, 30 are shown as being stacked upon each other as shown in FIG. 1. When the frames 28, 30 are deployed, the frames 28b, c and 30b, c may slide outward and also pivot into alignment with the frame 28a, 30a so that the frames 28a, b, c are in the same plane and the frames 30a, b, c are in the same plane. The frames 28b, c and 30b, c are shown as being offset from the frame 28a, 30a in FIG. 2. This shows the frames 28b,c, and 30b,c before they are pivoted into alignment with the frames 28a, 30a. 
The fairing 40 may also have a cutout to allow for the panels 42 which may be too wide for the fairings 40, as shown in FIG. 1. The cutout 46 allows the panels 42 to extend beyond the width of the fairing 40.
Referring now to FIGS. 7-14, the collapsible shell 112 will be discussed. The collapsible shell 112 is identical to the collapsible shell 12 discussed in relation FIGS. 1-6. However, certain differences do exist which are described below. The frames 28a, 30a may be fixedly attached to the sidewalls 22, 24. Additionally, a crossbar 148 may be attached to the frames 28, 30.
Moreover, the fairing 140 may additionally have a rear flap 150 that is flexible and pivotable about a rear edge 152 of the fairing 140. The fairing 140 may optionally not have the cutout 46 because the panels 142 of the cover 116 may be modified so as to be narrower than a width of the fairing 140. In particular, the panels 142 of the cover 116 is only wider than the fairing 140 because the panel 142d extends outward at the bottom so that the panel 142d can form an enclosure about the entire width of the upper edge 154 of the tailgate 156 of the truck 10. The panel 142d may have pivoting side flaps 158 which are folded inward as shown in FIG. 12 so that the panels 142 are narrower than the fairing 140 and can fit entirely within the fairing 140. For this reason, the cutout 46 placed in the fairing 40 is not required in the fairing 140. The fairing 140 may be traversable between the upper position and the down position in the same manner as that of fairing 40 with or without a spring to traverse the fairing 40 to the upward position and with or without a latch to hold the fairing 140 in the downward position. The same is true for fairing 40.
Additionally, the panel 142 are deployed in the same manner in relation to the panels 42 discussed in relation to FIGS. 1-6 except that in the embodiment shown in FIGS. 7-14, there is an extra step of unfolding the side flaps 158 outward for engaging the panel 142 to the closed position, as shown in FIG. 14.
Moreover, the collapsible shell 112 may have supporting cross members 160 that may be attached to the frames 28b, c and 30b, c, shown in FIG. 12. The supporting cross members 160 provide additional rigidity to the collapsible shell 112. Moreover, the cover 116 may have a pivoting joint 162 that allows the panels 142c and 142d to pivot about each other. The pivoting joint 162 may also be secured to the supporting crossmember 160 attached to the frames 28c, 30c. The cover 16 may be secured to the frames 28, 30 with latches including but not limited to rubber latches or mechanically operated latches.
The supporting crossmembers 160 may be stored under the fairing 141 the collapsible shell 112 is in the collapsed position. The supporting crossmembers 160 may be attached to the frames 28b, c and 30b, c with quick attach mechanisms known in the art or developed in the future. The crossmembers 160 and the frames 28, 30 may have quick detach mechanisms so that the supporting crossmembers 160 may be removably attached to the frames 28, 30 so that the supporting crossmember 160 may be stored in the fairing 140 when the collapsible shell 112 is in the collapsed position. Also, when needed, the supporting crossmember 160 may be removed from fairing 140 and attached to the frames 28b, c and 30b, c to attach to the frames 28, 30. The crossmembers 160 may be used to assist in deploying and storing the shell 12, 112.
The collapsible shell 12, 112 may be traversed from the stored or collapsed position to the extended position either manually or under the power of a motor. When done manually, the user will grasp the frame 28c and begin to pull the frame 28c toward the tailgate. Additionally, the user will grasp 30c and begin to pull the frame 30c toward the tailgate. By doing so, the frames 28b, c and 30b, c are traversed to the extended position. Alternatively, for the collapsible shell 112, the user may secure the supporting crossmember 160 to the frame 28c and 30c first and then grip the supporting crossmember 160 and traverse the supporting crossmember 160 toward the tailgate. By doing so, this also traverses the frames 28b, c and 30b, c toward the extended position simultaneously. It is also contemplated that the frames 28b, c and 30b, c may be traversed to the extended position under the power of a motor. The motor may drive a rack and pinion configuration attached to the frames 28b, c to either the frame 28a or sidewall 22. The same or different motor may also drive the rack and pinion configuration attached to the frames 30b, c attached to either the frame 38 or sidewall 24. The motor(s) may be actuated by a controller to either traverse the frames 28b, c, 30b, c to the extended position and/or back to the collapsed position.
The fairing 40, 140 are shown as being rotatably attached to the cab of the truck. However, the fairing 40, 140 may also be removable from the cab of the truck so that the user can remove the shell from the truck if desired. For example, truck cabs may have integrated rails on the driver side and passenger side of the cab of the truck. The fairing 40, 140 may be removably attached to the left and right rails on the top of the cab. The fairing 40, 140 may also be integrated into the cab of the truck in that it is not removable without significant time and effort.
The cover 16, 116 may have an integrated third brake light 17, 117. The third brake light 17, 117 may be in electrical communication with the electrical system of the truck so that the third brake light 17, 117 is illuminated when brakes of the truck are actuated. The third brake light 17, 117 may be disposed between panels 42c and 42d for the embodiment shown in FIGS. 1-6 and between panels 142c and 142d for the embodiment shown in FIG. 7-14.
The cover 16, 116 and the frames 28, 30, 128, 130 when in the deployed state shown in FIGS. 6 and 14 may be waterproof so that rain water does not and cannot enter the truck bed area. To this end, the cover 16, 116 and the frames 28, 30, 128, 130 may have rubber seals and other sealing mechanisms for keep the water out of the truck bed area.
The above description is given by way of example, and not limitation. Given the above disclosure, one skilled in the art could devise variations that are within the scope and spirit of the invention disclosed herein. Further, the various features of the embodiments disclosed herein can be used alone, or in varying combinations with each other and are not intended to be limited to the specific combination described herein. Thus, the scope of the claims is not to be limited by the illustrated embodiments.
