Claims

What is claimed is:

1. An accessory for a pick-up truck having a tailgate which is operable between open and closed positions, comprising (a) a mounting plate connected with a side edge portion of an interior surface of the tailgate, said mounting plate including a pair of spaced rigid posts extending normal to the tailgate surface, said posts being arranged in a plane parallel to a longitudinal axis of the truck; (b) a ladder assembly including a pair of spaced parallel legs pivotally connected with said posts for movement between a stowed position wherein said ladder assembly rests against the tailgate interior surface and an operable position wherein said ladder assembly extends from said posts to the ground laterally of the truck; and (c) a pair of links pivotally connected at opposite ends between one of said posts and one of said ladder legs, respectively, said links spacing said ladder assembly from a side edge of the tailgate when the ladder assembly is on the operable position and arranging said ladder assembly at different angles relative to the tailgate in accordance with the height of the tailgate relative to the ground.

2. An accessory as defined in claim 1, wherein said links include stops to limit the pivotal movement of the ladder assembly to prevent the ladder assembly from pivoting beyond an angle normal to the tailgate to prevent said ladder assembly from striking the tailgate when in the operable position.

3. An accessory as defined in claim 2, wherein said links have a length corresponding with the length of said posts.

4. An accessory as defined in claim 1, wherein said ladder assembly comprises a plurality of spaced steps connected between said legs.

5. An accessory as defined in claim 4, wherein said steps are pivotally connected with said legs, said steps being pivoted to a position wherein said steps are parallel to the tailgate interior surface when said ladder assembly is in the stowed position.

6. An accessory as defined in claim 1, and further comprising a latching mechanism connected with the interior surface of the tailgate in a location spaced from said mounting plate for retaining said ladder assembly in the stowed position.

7. An accessory as defined in claim 6, wherein said latch assembly comprises a spring-biased latch which grips a cross bar of said ladder assembly connected between said legs.

8. An accessory a defined in claim 1, wherein said ladder assembly is adjustable in length for operation on pick-up trucks having tailgates spaced from the ground at different heights.

9. An accessory as defined in claim 1, and further comprising a handle connected with an interior rear portion of a side wall of the truck.

10. An accessory for a pick-up truck having a tailgate which is operable between open and closed positions, comprising (a) a mounting plate connected with a side edge portion of an interior surface of the tailgate, said mounting plate including a pair of spaced rigid posts extending normal to the tailgate surface; (b) a ladder assembly pivotally connected with said posts for movement between a stowed position wherein said ladder assembly rests against the tailgate interior surface and an operable position wherein said ladder assembly extends from said posts to the ground; and (c) a handle connected with an interior rear portion of a side wall of the truck, wherein said handle is pivotally connected with said truck side wall for movement between an upright operable position when the tailgate is lowered to the open position and a horizontal stowed position when the tailgate is raised to its closed position.

11. An accessory as defined in claim 10, and further comprising a spring-biased hinge connecting said handle with said truck side Wall, said hinge normally biasing said handle toward its stowed position.

12. An accessory as defined in claim 11, and further comprising a cable connected between said handle and the tailgate for raising said handle to the upright position when the tailgate is lowered.

13. An accessory as defined in claim 10, wherein said linkage assembly extends across a portion of said handle when said handle and said ladder assembly are in their stowed positions and the tailgate is in the closed position.
