DETAILED DESCRIPTION
Referring in general to all of the Figures there is illustrated, as best shown in FIG. 1, a pickup truck cargo compartment 10 that may include a pair of sidewalls 14 and 16. The sidewalls 14 and 16 may be oppositely disposed along the longitudinal sides of the bed 12, and may project generally perpendicularly upward from the bed. The bed 12 may terminate at a rear edge 18 of the cargo compartment at which location a tailgate door or other suitable barrier may be attached. While a pickup truck cargo compartment is represented in the FIG. 1, those skilled in the art may appreciate that the teachings of this disclosure may be generally applicable and adapted to any type of vehicle equipped with a cargo bed adapted to transport cargo.
In accordance with the features of the present disclosure, there is shown a bed extension 22 that may be attached to the bed 12 of the truck cargo compartment 10 at its rear edge 18, and may serve to safely accommodate oversized cargo on the bed 12 that would otherwise extend beyond the rear edge 18 of the cargo compartment 10. The bed extension 22 may include a substantially planar loading platform or ramp 24 which may be pivotably attached to the tailgate door 20 near the top thereof. The loading platform 24 may be substantially the same width as the tailgate door 20. The lateral ends of the loading platform 24 may include an extended lug portion 26, along each side thereof, to pivotably attach the bed extension 22 to the tailgate door 20. Each lug portion 26 may include a guide slot 36 for receiving a mounting bolt 30 after the extended lug portions 26 are placed into a boss 32 that may be securely attached at each side to the tailgate door 20. To avoid interference with loading or unloading of cargo, the boss 32 may be located in a recess in the inner panel of the tailgate door to avoid being an obstacle to loading or unloading cargo—particularly when the loading platform 24 may be removed. In fact, it is contemplated that each lug portion 26 of the bed extender may be coupled or attached to a cross-pin (not shown) mounted underneath the bed 12 of the cargo compartment 10 to avoid the use of a boss 32 that could become a hindrance to loading or unloading cargo.
Referring in particular to FIGS. 3 through 5, the bed extension 22 may assume any one of three positions other than its storage position. FIG. 3 illustrates a position at 90 degrees to the horizon, after the tailgate door 20 has been opened. In this vertical position, the bed extension 22 may be locked so that the bed extension 22 retains oversized cargo within the cargo compartment 10. FIG. 4 illustrates a position 180 degrees from its storage position or substantially co-planar with the cargo bed 12 so that it substantially extends the length of the tailgate and may support cargo. In this embodiment, it is contemplated that the tailgate and/or the bed extension may include any of a variety of cargo securing devices including an extension member or strap for securing cargo.
As in the 90 degree position, the bed extension 22 may be locked to prevent it from further rotation. In this position, the bed extension 22 provides support for cargo of extended loads. The bed extension 22 may be rotatably deployed to 210 degrees, as shown in FIG. 5, and locked in position to receive two loading ramps 34 that may be stored within passaged located in the tailgate door 20, as shown in FIG. 7. FIG. 1 best illustrates the two loading ramps attached and locked to the bed extension 22 with the bed extension 22 deployed or rotated and locked at 210 degrees from the stowed position against the inner panel of the tailgate door 20. In this position, wheeled vehicles, such as ATV, motorcycles, mowers and/or lawn or any other known device (including a human) may more easily be loaded into the cargo compartment of the vehicle equipped with the device of the present disclosure.
FIG. 8 is a close-up of the extended lug portion 26 of the bed extension 22 which illustrates the guide slot 36 which may cut into the extended lug portion 26 to provide the three locked positions of the bed extension 22. The position shown in FIG. 8 is the bed extension located at approximately 210 degrees from the horizontal plane such as that defined by the bed of the pickup truck vehicle. The bolt 30 may be at the end of the guide slot 36 when the bed extension 22 is rotated to the horizontal position 180 degrees from the horizontal plane such as that defined by the bed of the pickup truck vehicle and the bolts 30 may move into the opposing ends 38 of the guide slots 36. With the bed extension in a vertical position as best shown in FIG. 3, the bolt 30 may be locked into the medial slot 40 so that the bed extension retains oversized cargo in the cargo bed.
A further feature of the present disclosure is that the cargo bed extension 22 may include the passages for receiving and retaining the ramps, illustrated in FIG. 1, for providing readily and always available easy access to the cargo bed for wheeled vehicles and equipment such as an ATV, motorcycle, a lawn tractor or mower.
An alternate end bracket and channel design is shown in FIG. 29 for coupling the tailgate to the cargo area of the vehicle.
As disclosed hereinabove, the cargo bed extension may be designed to fold and lock into four (4) distinct positions. When not in use, as shown in FIG. 6, the bed extension 22 may be folded and secured to the inner sidewalls of the tailgate door 20. While in the stowed position, the bed extension 22 may be locked or, alternatively, may be secured to the sidewall of the tailgate door 20 with any suitable type of latch. As best shown in FIG. 1, the height of the bed extension may not be greater than and approximately equal to, the height of the sidewalls 14, 16 above the bed 12 of the cargo area but it is contemplated that other arrangements are possible. As such, the bed extension 22 does not project above the sidewalls 14, 16 when the bed extension 12 is in its stowed and locked position.
After the tailgate door 20 is lowered, the bed extension 22 may be rotated to a 90 degree vertical position and locked at such position. In this position, the bed extension retains oversized cargo within the cargo bed. The bed extension 22 may be further deployed to 180 degrees so that it may be located substantially co-planar with the cargo bed 12. In this position, the bed extension 22 may be locked to receive and support cargo including extended loads. Lastly, the bed extension 22 may be further rotated to approximately 210 degrees from the horizontal plane as defined by the bed of the pickup truck vehicle and locked into place in order to receive the two loading ramps 34 that are stored within the confines of the tailgate door 20 as best shown in FIG. 7.
Alternative arrangements are possible in view of the present disclosure.
