Description

TECHNICAL FIELD

This disclosure relates to a pick-up truck tailgate that includes a lifting apparatus.

BACKGROUND

Pick-up truck beds are used to transport a wide variety of objects. Objects transported in pick-up truck beds can be heavy or large, such as deer or logs, making them difficult to load. Loading heavy or large objects may require help. However, sometimes help is unavailable, for example, when hunting or working in a remote location alone. Lifting heavy objects alone can be impossible, and may result in injury. When the object is lifted and placed in the truck bed, the object may still need to be pushed further into the truck bed to allow the tailgate to close. Pushing the object into the truck bed may also require help, causing the same problem as discussed above.
The prior art discloses replacing the tailgate of the truck with a lift for assisting in lifting objects with a four bar linkage into to the truck bed. The prior art does not address pushing the object into the truck bed to allow the tailgate to close or to make room for more objects to be loaded. The prior art also includes problems such as removing the tailgate or assembling a ramp and a four bar linkage. Removing the tailgate is time consuming and there is a risk of damaging the tailgate. Assembling a ramp and a four bar linkage can be costly, complicated, and difficult due to the heavy weight of the ramp and linkage. A four bar linkage is also not easily detachable.
This disclosure is directed to solving the above problems and other problems summarized below.

SUMMARY

According to one aspect of this disclosure, a tailgate assembly is provided including a tailgate and a bracket selectively attachable to the tailgate. An L-shaped platform is attached to the bracket by a pivot connector adjacent the top/rear edge of the tailgate. A retractable link is attached to the bracket to pivot the L-shaped platform about the pivot connector.
The L-shaped platform includes a first wall fixed to a second wall at a corner at an angle defining a recess. The L-shaped platform pivots between an extended position with the first wall substantially parallel to the truck bed and the second wall substantially perpendicular to the truck bed, and a retracted position with the first wall substantially perpendicular to the truck bed and the second wall substantially parallel to the truck bed. The L-shaped platform can also pivot further to an inclined position and a stowed position.
The retractable link may include a reel attached to the bracket, and a cable having a first end secured to the reel and a second end attached to a distal end of the L-shaped platform. The reel may include a handle. Alternatively, the retractable link may include a power cylinder having a head portion attached to the bracket and a rod portion attached to a distal end of the L-shaped platform.
According to another aspect of this disclosure, a loading apparatus for a truck bed is provided comprising a bracket selectively attachable to a tailgate. A load receptacle is pivotally attached to the bracket. The load receptacle includes a first platform attached to a second platform at a corner at an angle to define a recess. A reel is attached to the bracket for use with a cable. The cable has a first end secured to the reel and a second end attached to a distal end of the first platform.
The load receptacle may have a substantially L-shaped cross section and may include a support brace connecting a distal end of the first platform to a distal end of the second platform. The load receptacle may be pivotally attached to the bracket above a distal end of the tailgate when the tailgate is open.
The load receptacle is pivotable between an extended position, a retracted position, an inclined position, and a stowed position. When the tailgate is open, in the extended position the first wall is substantially parallel to the truck bed and the second wall is substantially perpendicular to the truck bed. In the retracted position, the first platform is substantially perpendicular to the truck bed and the second platform is substantially parallel to the truck bed. The L-shaped platform is in the inclined position when pivoted to a position between the retracted position and the stowed position. When the tailgate is closed and the L-shaped platform is in the stowed position, the first wall is substantially perpendicular to the truck bed, and the second wall is substantially parallel to the truck bed. The distal end of the first wall may be in contact with the truck bed when the L-shaped platform is in the stowed position.
According to another aspect of this disclosure, a loading apparatus for a truck bed is provided that includes a bracket selectively attached to a tailgate. A load receptacle may be pivotally attached to the bracket. The load receptacle includes a first platform attached to a second platform at a corner at an angle to define a recess. A power cylinder is used to pivot the L-shaped platform between an extended position, a retracted position, an inclined position, and a stowed position. The power cylinder includes a cylinder portion attached to the bracket and a rod portion attached to a distal end of the first platform. The power cylinder may be hydraulic or pneumatic.
