Abstract

An integrated stepgate and handle assembly includes a tailgate, a displaceable ladder carried on the tailgate, a displaceable handle carried on the tailgate and a latch. The latch connects the ladder and the handle whereby the handle is partially deployed with the ladder. This partial deployment of the handle prompts the operator to fully deploy and use the handle.

First claim

What is claimed:

1. An integrated stepgate and handle assembly, comprising:
a tailgate;
a ladder displaceable between a storage position within said tailgate and a use position;
a handle displaceable between a stowed position within said tailgate and a deployed position; and
a latch connecting said ladder and said handle whereby said handle is partially deployed as said ladder is displaced toward said use position; and
a first pivot for mounting a first end of said latch to said ladder.

2. The assembly of claim 1 , wherein a second end of said latch includes a catch and a cam.

3. The assembly of claim 2 , wherein said handle includes a shaft and a knob and said latch is spring biased into a latching position wherein said catch engages said knob.

4. The assembly of claim 3 , wherein said ladder includes a u-shaped rail having a first pivot pin at a first end and a second pivot pin at a second end.

5. The assembly of claim 4 , wherein said ladder further includes a step carried on said rail.

6. The assembly of claim 4 , further including a guide track in said tailgate, said rail being received and held in said guide track when said ladder is in said storage position.

7. The assembly of claim 6 , further including a first receiver and a second receiver on said tailgate, said first pivot pin being received in said first receiver and said second pivot pin being received in said second receiver when said ladder is deployed into an intermediate position between said storage position and said use position.

8. The assembly of claim 7 , wherein said ladder is connected by said latch to said handle as said ladder translates along and relative to said guide track when displaced between said storage position and said intermediate position thereby partially deploying said handle and said ladder is pivoted about said first and second pivot pins from said intermediate position into said use position thereby releasing said latch from engagement with said handle.

9. The assembly of claim 8 , wherein said handle includes a second pivot whereby said handle may be pivoted from a reclined position to an upright position when fully extended from said tailgate.

10. The assembly of claim 9 , further including an instruction label on said shaft where it is prominently displayed when said handle is in said partially deployed position.

11. A method of deploying an integrated stepgate and handle assembly including a ladder and a handle, comprising:
displacing said ladder from a storage position in a vehicle tailgate to an intermediate position;
temporarily connecting said ladder to said handle whereby said handle is pulled into a partially deployed position as said ladder is displaced from said storage position to said intermediate position;
displacing said ladder from said intermediate position to a use position; and
disconnecting said ladder from said handle as said ladder is displaced from said intermediate position to said use position thereby leaving said handle in said partially deployed position.

12. The method of claim 11 , further including displacing said handle into a fully deployed and upright position.

13. The method of claim 12 , wherein said ladder is displaced from said storage position to said intermediate position by sliding said ladder out of said tailgate.

14. The method of claim 13 , wherein said ladder is displaced from said intermediate position to said use position by pivoting about a first axis.

15. The method of claim 14 , wherein said handle is displaced from the partially deployed position to the fully deployed position by first sliding out of said tailgate and then pivoting about a second axis.

16. An integrated stepgate and handle assembly, comprising:
a tailgate;
a ladder displaceable between a storage position within said tailgate and a use position;
a handle displaceable between a stowed position within said tailgate and a deployed position; and
a latch connecting said ladder and said handle whereby said handle is partially deployed as said ladder is displaced toward said use position, wherein a second end of said latch includes a catch and a cam.

17. The assembly of claim 16 , wherein said handle includes a shaft and a knob and said latch is spring biased into a latching position wherein said catch engages said knob.

18. The assembly of claim 17 , wherein said ladder includes a u-shaped rail having a first pivot pin at a first end and a second pivot pin at a second end.

19. The assembly of claim 18 , wherein said ladder further includes a step carried on said rail.

20. The assembly of claim 19 , further including a guide track in said tailgate, said rail being received and held in said guide track when said ladder is in said storage position.
