Abstract

A step assembly for a tailgate of a vehicle, which includes a retractable rail secured to a housing located within the tailgate. The retractable rail is configured to extend from the housing and the tailgate when in a deployed state, and be entirely received within the housing and the tailgate when in a non-deployed state. A sliding stop device is positioned within the housing and connected to an end of the retractable rail. The stop device includes a tubular member having an aperture formed therein, and a movable arm located in the tubular member that is biased to extend outward from the aperture such that as the retractable rail is moved to the deployed state, the aperture of the sliding stop device is aligned with the opening of the housing, and the movable arm is engaged with the opening.

First claim

What is claimed is:

1. A step assembly for a tailgate of a vehicle, comprising:
a housing located within an interior of the tailgate, and including an opening in a side surface thereof;
a retractable rail secured to the housing, the retractable rail configured to extend from the housing and the tailgate when in a deployed state, and configured to be entirely received within the housing and the tailgate when in a non-deployed state;
a bumper stop pad mounted to the retractable rail; and
a sliding stop device positioned within the housing and connected to an end of the retractable rail, the stop device including a tubular member having an aperture formed therein, and a movable arm located in the tubular member and biased to extend outward from the aperture,
wherein as the retractable rail is moved from the non-deployed to the deployed state, the aperture of the sliding stop device is aligned with the opening of the housing, and the movable arm that extends outward from the aperture is engaged with the opening.

2. The step assembly according to claim 1 , wherein the retractable rail is pivotably connected to the sliding stop device such that when the retractable rail is in the deployed state, the retractable rail can be pivoted relative to the tailgate toward the ground.

3. The step assembly according to claim 1 , further comprising a step attached to the retractable rail, the step being pivotable relative to the retractable rail.

4. The step assembly according to claim 1 , wherein the bumper stop pad is mounted to the retractable rail by a pair of mounting plates that permit the bumper stop pad to be moved towards and away from retractable rail.

5. The step assembly according to claim 1 , further comprising a locking lever positioned within the retractable rail that is configured to lock the retractable rail to the housing when the retractable rail is in the non-deployed state.

6. The step assembly according to claim 5 , wherein the locking lever includes a finger grip end that extends through an end cap of the retractable rail that is configured for manually manipulating the locking lever between a locked and unlocked position.

7. The step assembly according to claim 5 , wherein the locking lever includes a lock ending end that is configured to engage with a locking port formed in the housing.

8. The step assembly according to claim 1 , wherein the housing includes a mounting bracket that is secured to the tailgate by a fastener.

9. A step assembly for a tailgate of a pickup truck, comprising:
an elongated tubular housing located within an interior of the tailgate, and including a pair of openings formed in opposing side surfaces thereof;
an elongated tubular retractable rail slidably received within the housing, the retractable rail configured to extend from the housing and the tailgate when in a deployed state, and configured to be entirely received within the housing and the tailgate when in a non-deployed state;
a locking lever positioned within the retractable rail that is configured to lock the retractable rail to the housing when the retractable rail is in the non-deployed state;
a sliding stop device positioned within and slidable relative to the housing and hingedly connected to an end of the retractable rail, the stop device including a tubular member having a pair of opposing apertures formed therein, and a pair of movable arms located in the tubular member that are spring-biased to extend outward from the opposing apertures; and
a step pivotably attached to an end of the retractable rail;
wherein as the retractable rail is moved from the non-deployed to the deployed state, the apertures of the sliding stop device are aligned with the openings of the housing, and the movable arms that extend outward from the apertures are engaged with the openings to prevent further movement of sliding stop device and the retractable rail relative to the housing.

10. The step assembly according to claim 9 , wherein the retractable rail is hingedly connected to the sliding stop device by a pair of brackets that are each connected to a pivot pin such that when the retractable rail is in the deployed state, the retractable rail can be pivoted relative to the tailgate toward the ground.

11. The step assembly according to claim 9 , further comprising a bumper stop pad mounted to the retractable rail.

12. The step assembly according to claim 11 , wherein the bumper stop pad is mounted to the retractable rail by a pair of mounting plates that permit the bumper stop pad to be moved towards and away from retractable rail.

13. The step assembly according to claim 9 , wherein the locking lever includes a finger grip end that extends through an end cap of the retractable rail that is configured for manually manipulating the locking lever between a locked and unlocked position.

14. The step assembly according to claim 9 , wherein the locking lever includes a lock ending end that is configured to engage with a locking port formed in the housing.

15. The step assembly according to claim 9 , wherein the housing includes a mounting bracket that is secured to the tailgate by a fastener.

16. A step assembly for a tailgate of a vehicle, comprising:
a housing located within an interior of the tailgate, and including an opening in a side surface thereof;
a retractable rail secured to the housing, the retractable rail configured to extend from the housing and the tailgate when in a deployed state, and configured to be entirely received within the housing and the tailgate when in a non-deployed state;
a sliding stop device positioned within the housing and connected to an end of the retractable rail, the stop device including a tubular member having an aperture formed therein, and a movable arm located in the tubular member and biased to extend outward from the aperture;
a step pivotably attached to an end of the retractable rail; and
a locking lever positioned within the retractable rail that is configured to lock the retractable rail to the housing when the retractable rail is in the non-deployed state,
wherein the locking lever includes a finger grip end that extends through an end cap of the retractable rail that is configured for manually manipulating the locking lever between a locked and unlocked position, and configured for pulling the retractable rail from the housing; and
wherein as the retractable rail is moved from the non-deployed to the deployed state, the aperture of the sliding stop device is aligned with the opening of the housing, and the movable arm that extends outward from the aperture is engaged with the opening to prevent further movement of sliding stop device and the retractable rail relative to the housing.

17. The step assembly according to claim 16 , wherein the retractable rail is hingedly connected to the sliding stop device by a pair of brackets that are each connected to a pivot pin such that when the retractable rail is in the deployed state, the retractable rail can be pivoted relative to the tailgate toward the ground.

18. The step assembly according to claim 16 , further comprising a bumper stop pad mounted to the retractable rail.
