Abstract

A retractable vehicle step is attachable to a vehicle or truck, such as at the rear portion. The vehicle step facilitates access to a cargo hold of the vehicle. Advantageously, the vehicle step provides clearance space relative to a tailgate of the vehicle by displacing a stepping member of the vehicle step in a generally lateral direction. The vehicle step desirably has a covered and protected biasing mechanism for transitioning between retracted and extended positions of the stepping member. Another advantage is that the vehicle step is readily attachable to the vehicle using already existing connection members, thereby generally eliminating or mitigating the need for customized retrofitting and avoiding undesirable installation cost and time. Further, the vehicle step may be pulled out from under the vehicle by the foot of a user.

First claim

What is claimed is:

1. A retractable vehicle step comprising:
a stepping platform;
a mounting bracket configured to be attached to a vehicle; and
at least one extension arm connecting the stepping platform to the mounting bracket and being pivotably connected to the stepping platform and mounting bracket;
wherein the retractable vehicle step is configured to translate from a retracted position located in-board relative to a side of the vehicle to an extended position wherein the stepping platform is located substantially outboard relative to the side of the vehicle;
wherein, in the extended position, the stepping platform extends generally parallel to a horizontal plane when the vehicle is supported by a horizontal surface; and
wherein the stepping platform comprises an attachment portion curving upwards and in-board from an in-boardmost portion of the stepping platform to form a channel, the channel configured to receive a portion of the vehicle.

2. The retractable vehicle step of claim 1 , wherein the stepping platform comprises a front edge, wherein the front edge remains in approximately the same vertical position in the retracted position and in the extended position when the vehicle is supported by a horizontal surface.

3. The retractable vehicle step of claim 1 , wherein the stepping platform is configured to move generally from a lowered position in the retracted position to a raised position in the extended position when translated between the retracted position to the extended position.

4. The retractable vehicle step of claim 1 , further comprising a biasing mechanism.

5. The retractable vehicle step of claim 1 , wherein the retractable vehicle step comprises two extension arms, each of which is individually and rotatably attached to the stepping platform.

6. The retractable vehicle step of claim 1 , wherein the retractable vehicle step is self-energizing.

7. The retractable vehicle step of claim 1 , wherein the stepping platform rotates between the retracted position and the extended position.

8. The retractable vehicle step of claim 1 , wherein, in the retracted position, the stepping platform extends upward at an acute angle from a horizontal plane when the vehicle is supported by a horizontal surface.

9. A vehicle having a retractable vehicle step, the retractable vehicle step comprising:
a stepping platform;
a mounting bracket configured to be attached to the vehicle; and
at least one extension arm connecting the stepping platform to the mounting bracket and being pivotably connected to the stepping platform and mounting bracket;
wherein the retractable vehicle step is configured to translate from a retracted position located in-board relative to a side of the vehicle to an extended position wherein the stepping platform is located substantially outboard relative to the side of the vehicle;
wherein, in the extended position, the stepping platform extends generally parallel to a horizontal plane formed when the vehicle is supported by a horizontal surface; and
wherein the stepping platform comprises an attachment portion curving upwards and in-board from an in-boardmost portion of the stepping platform to form a channel, the channel configured to receive a portion of the vehicle.

10. The vehicle of claim 9 , wherein the stepping platform comprises a front edge, wherein the front edge remains in approximately the same vertical position in the retracted position and in the extended position when the vehicle is supported by a horizontal surface.

11. The vehicle of claim 9 , wherein the stepping platform is configured to move generally from a lower position in the retracted position to a raised position in the extend position when translated between the retracted position to the extended position.

12. The vehicle of claim 9 , further comprising a biasing mechanism.

13. The vehicle of claim 9 , wherein the retractable vehicle step comprises two extension arms, each of which is individually and rotatably attached to the stepping platform.

14. The vehicle of claim 9 , wherein the retractable vehicle step is self-energizing.

15. The vehicle of claim 9 , wherein the stepping platform rotates between the extended position and the retracted position.

16. The vehicle of claim 9 , wherein, in the retracted position, the stepping platform extends upward at an acute angle from the horizontal plane when the vehicle is supported on a horizontal surface.
