Abstract

A vehicle includes a cargo bed having a floor, side walls and a rear end opening with an endgate pivotally connected at the rear end opening. The endgate is pivotable between a vertical position covering the rear end opening and a horizontal position exposing the rear end opening for cargo loading and unloading. The endgate has a pass-through opening formed therein and includes a door integrally contained within the endgate. The door is pivotable with respect to the endgate between a closed position covering the pass-through opening and an open position to allow loading and unloading of cargo through the pass-through opening when the endgate is in the vertical position.

Claims (47)

1. A vehicle comprising:

a cargo bed having a floor, two vertical side walls and a rear end opening;

an endgate having a fixed hinge connected at the rear end opening along a lower horizontal edge so that the endgate is pivotable between a vertical position covering the rear end opening and a horizontal position exposing the rear end opening for cargo loading and unloading; and

said endgate having a pass-through opening formed therein smaller than the rear end opening of the cargo bed and including a door integrally contained within said endgate and biased towards one of said side walls, said door being pivotable with respect to said endgate between a closed position covering said pass-through opening and an open position to allow loading and unloading of the cargo through the pass-through opening when the endgate is in the vertical position.

2. The vehicle of claim 1 , further comprising an electrically actuated endgate latch operatively connected between the endgate and side walls for selectively latching and unlatching the endgate.

3. The vehicle of claim 2 , further comprising an electrically actuated door latch operatively connected between the door and endgate for selectively latching and unlatching the door.

4. The vehicle of claim 3 , further comprising a rocker switch positioned below an endgate pull cup for actuating said latches.

5. The vehicle of claim 1 , wherein the endgate and door pivot about a common horizontal axis.

6. The vehicle of claim 1 , wherein said endgate includes an aluminum tube frame structure enclosed by trim cover panels.

7. A vehicle comprising:

a cargo bed having a floor, two vertical side walls and a rear end opening;

an endgate having a fixed hinge connected at the rear end opening Ualong a lower horizontal edge so that the endgate is pivotable between a vertical position covering the rear end opening and a horizontal position exposing the rear end opening for cargo loading and unloading;

said endgate having a pass-through opening formed therein and including a door integrally contained within said endgate and biased towards one of said side walls, said door being pivotable with respect to said endgate between a closed position covering said pass-through opening and an open position to allow loading and unloading of the cargo through the pass-through opening when the endgate is in the vertical position; and

at least one torsional load assist spring operatively connected between said endgate and said side walls to minimize operating efforts.

8. The vehicle of claim 7 , further comprising an electrically actuated endgate latch operatively connected between the endgate and side walls for selectively latching and unlatching the endgate.

9. The vehicle of claim 8 , further comprising an electrically actuated door latch operatively connected between the door and endgate for selectively latching and unlatching the door.

10. The vehicle of claim 9 , further comprising a disabler switch operatively connected with said electrically actuated latches to enable the latches when a corresponding vehicle transmission is in a parked condition, and to disable the latches when the transmission is not in the parked condition.

11. The vehicle of claim 7 , wherein the endgate and door pivot about a common horizontal axis.

12. A vehicle comprising

a cargo bed having a floor, side walls and a rear end opening;

an endgate having a fixed hinge connected at the rear end opening so that the endgate is pivotable between a vertical position covering the rear end opening and a horizontal position exposing the rear end opening for cargo loading and unloading;

said endgate having a pass-through opening formed therein and including a door integrally contained within said endgate, said door being pivotable with respect to said endgate between a closed position covering said pass-through opening and an open position to allow loading and unloading of the cargo through the pass-through opening when the endgate is in the vertical position;

at least one torsional load assist spring operatively connected between said endgate and said side walls to minimize operating efforts;

an electrically actuated endgate latch operatively connected between the endgate and side walls for selectively latching and unlatching the endgate;

an electrically actuated door latch operatively connected between the door and endgate for selectively latching and unlatching the door; and

a rocker switch positioned below an endgate pull cup for actuating said latches.

13. The vehicle of claim 12 , further comprising a relay circuit operatively associated with said rocker switch and configured such that only the endgate or door may be unlatched at one time.

14. The vehicle of claim 12 , wherein said endgate includes an aluminum tube frame structure enclosed by trim cover panels.

15. The vehicle of claim 12 , further comprising load assist straps connected between the endgate and side walls to support the endgate in the horizontal position.

16. A vehicle comprising:

a cargo bed having a floor, side walls, and a rear end opening;

an end gate having a fixed hinge connected at the rear end opening so that the endgate is pivotable between a vertical position covering the rear end opening and a horizontal position exposing the rear end opening for cargo loading and unloading;

said end gate having a pass-through opening formed therein and including a door integrally contained within said end gate, said door being pivotable with respect to said end gate between a closed position covering said pass-through opening and an open position to allow loading and unloading of the cargo through the pass-through opening when the end gate is in the vertical position;

an electrically actuated end gate latch operatively connected between the end gate and side walls for selectively latching and unlatching the end gate:

an electrically actuated door lath operatively connected between the door and end gate for selectively latching and unlatching the door;

a rocker switch positioned on the end gate for actuating said latches;

a relay circuit operatively associated with said rocker switch and configured such that only the end gate or door may be unlatched at one dine; and

a disabler switch operatively connected with said relay circuit to enable the latches when a corresponding vehicle transmission is in a parked condition, and, to disable the latches when the transmission is not in the parked condition.

17. A vehicle comprising:

a cargo bed having a floor, side walls and a rear end opening;

an endgate having a fixed hinge connected at the rear end opening so that the endgate is pivotable between a vertical position covering the rear end opening and a horizontal position exposing the rear end opening for cargo loading and unloading;

said endgate having a pass-through opening formed therein and including a door integrally contained within said endgate, said door being pivotable with respect to said endgate between a closed position covering said pass-through opening and an open position to allow loading and unloading of cargo through the pass-through opening when the endgate is in the vertical position;

an electrically actuated endgate latch operatively connected between the endgate and the side walls for selectively latching and unlatching the endgate;

an electrically actuated door latch operatively connected between the door and the endgate for selectively latching and unlatching the door; and

a rocker switch positioned below an endgate pull cup for actuating said latches.

18. The vehicle of claim 17 , further comprising a relay circuit operatively associated with said rocker switch and configured such that only the endgate or door may be unlatched at one time.

19. The vehicle of claim 17 , further comprising load assist straps connected between the endgate and side wails to support the endgate in the horizontal position.
