The present invention relates generally to a tailgate assembly for a pickup truck, in particular to a fold-down tailgate having a swing-open door assembly.
Pickup trucks typically have a truck bed defined by a floor, a front wall and two side walls, leaving a rectangular opening at the rear. The rear of the truck bed is normally closed off by a tailgate. Most tailgates are positionable between a generally vertical closed position and a generally horizontal open position that is substantially level with the bed. The bed has significant utility, providing a convenient space to haul cargo. In addition, many pickup trucks now include storage containers built into the floor of the bed for storing objects such as tools and cargo.
Many people experience trouble accessing the bed of a pickup because they are not tall enough to reach over the side walls of the bed or a closed tailgate. Similarly it can be difficult to reach across an open tailgate to access the bed. Such difficulties are especially prevalent with larger pickups, as the height of the bed can be considerable.
Others have attempted to overcome these drawbacks by mounting steps or ladders to the pickup, such as U.S. Pat. Nos. 7,168,721 to Mulder, 7,080,713 to Riggs and 6,685,204 to Hehr. However, these devices often consume cargo space, add weight to the vehicle and/or detract from the vehicle's appearance. Furthermore, there is a risk of injury from falling off the step or ladder. Accordingly, there is a need for a means by which one can access the bed of a pick-up truck easily with a minimal amount of stress or effort.
A fold-down tailgate having a swing-open door is disclosed according to an embodiment of the present invention. The tailgate includes a generally U-shaped tailgate frame that is coupled to the bed of a pickup truck along its lower edge and is pivotable about a first axis between a generally vertical closed position and a generally horizontal open position that is substantially level with the bed. A door assembly is coupled to the frame and is pivotable about a second axis generally normal relative to the first axis for movement between a closed position and a swing-open position. In use, the tailgate can be operated in the normal manner, being positionable between a generally vertical closed position and a generally horizontal open position. In addition, when the tailgate is closed the door is positionable between a closed position that closes off the bed of the pickup and a swing-open position that provides a user with access to the bed without the need to reach over the side walls or the tailgate.
An aspect of the present invention is a tailgate for the bed of a pickup truck. The tailgate has a generally U-shaped tailgate frame that is adapted to be coupled to the bed of the pickup truck and is pivotable about a first axis between a generally vertical closed position and a generally horizontal open position. A door assembly is coupled to the tailgate frame and is pivotable about a second axis generally normal relative to the first axis for movement between a closed position proximate the tailgate frame and an open position away from the tailgate frame.
Another aspect of the invention is another embodiment of the tailgate for the bed of a pickup truck. The tailgate comprises a generally U-shaped tailgate frame that is adapted to be coupled to a bed of the pickup truck and is pivotable about a first axis between a generally vertical closed position and a generally horizontal open position, the tailgate frame being releasably latched to side walls of the pickup truck. A door assembly is coupled to the tailgate frame and is pivotable about a second axis generally normal relative to the first axis for movement between a closed position proximate the tailgate frame and an open position away from the tailgate frame. The door assembly is also releasably latched to the tailgate frame. An opening is formed in the door assembly, the opening being covered with a covering material comprising at least one of a metal panel, a plastic panel, a glass panel and a mesh material. The tailgate further includes a pair of tethers, each tether extending between a side wall of the pickup truck and a nearby arm of the tailgate frame and having a predetermined length to limit downward travel of the tailgate in the open position. A travel limiter is interposed between the tailgate frame and the door assembly to limit the travel of the door assembly to a predetermined maximum open position with respect to the tailgate frame.
Further features of the inventive embodiments will become apparent to those skilled in the art to which the embodiments relate from reading the specification and claims with reference to the accompanying drawings, in which:
The general arrangement of a tailgate 10 for a pickup truck is shown in
With reference now to
An exploded view showing the assembly of tailgate 10 is shown in
Tailgate 10 is assembled by coupling tailgate release handle 18 to tailgate frame 26. A pair of tailgate latches 44 are likewise coupled to opposing left and right arms 46a, 46b respectively of tailgate frame 26. One or more actuating cables 48, such as a Bowden cable, are operatively coupled between tailgate release handle 18 and tailgate latches 44 such that the tailgate latches are released when the tailgate release handle is actuated. A pair of caps 50 are joined to arms 46a, 46b to close off the arms. A door striker 52 is also attached to tailgate frame 26 to engage door latch 40.
Door 24 is coupled to tailgate frame 26 by one or more door hinges 28, and is releasably secured to the tailgate frame by door latch 40 in cooperation with door striker 52. Tailgate 10 is in turn coupled to bed 12 by one or more hinges 16 extending between lower edge 14 of the tailgate and the bed, and is releasably secured to side walls 22 by tailgate latches 44 in cooperation with corresponding tailgate strikers 54 attached to the side walls. A pair of tethers 20 are each attached at a first end to a side wall 22 and extend to tailgate 10, each being attached to a nearby arm 46a, 46b of tailgate frame 26 as shown in
In a first operational mode, tailgate 10 is held in a generally vertical closed position (
In a second operational mode, when tailgate 10 is to be lowered from the closed position to the open position tailgate release handle 18 (
In a third operational mode, when door assembly 24 is to be pivoted from its closed position to an open position door release handle 30 is actuated (
With door assembly 24 in an open position a user can easily reach bed 12 of the pickup truck to load or remove cargo stored therein. Similarly, a user may easily access a storage compartment such as storage compartment 60 (
When door assembly 24 is to be closed the door assembly is pivoted toward tailgate frame 26, causing latch 40 to engage striker 52. Latch 40 and striker 52 cooperate to retain the door in the closed position.
