Abstract

A hitch-mountable, collapsible stair assembly is disclosed for use in assisting mounting into a raised vehicle bed. The steps rotate between a generally vertical stowed position and a generally horizontal in-use position. The height of the steps above the ground is adjustable. The lower step can also be extended for ease of use.

Claims (16)

1. A collapsible stair assembly mountable to a vehicle hitch receiver for providing ease of access to a vehicle bed, the assembly comprising:

an insert releasably attachable to a vehicle hitch receiver;

a mounting bracket attached to the insert, wherein the mounting bracket is releasably attachable to a step subassembly, the mounting bracket defining multiple attachment points of varying height in relation to the vehicle bed for adjustable mounting of the step subassembly;

the step subassembly having multiple steps including an upper and a lower step, each step defining a generally planar support surface for supporting a user, each step pivotally movable between a generally vertical stowed position in which the support surface is generally vertically oriented and a generally horizontal in-use position in which the support surface is generally horizontally oriented, each step releasably secured in either the stowed or in-use position, wherein the step subassembly comprises a lower movable support attachable to the lower step, the lower movable support pivotal between the stowed and the in-use position, wherein the lower step slidingly engages a cooperating receptacle defined in the lower movable support; and

the lower step slidably movable between a home position relatively closer to the vehicle and an extended position relatively further from the vehicle, the support surface of the lower step generally horizontally orientated during sliding movement between the home and extended positions, wherein the lower step is usable for supporting a user whether in the home position or extended position.

2. The assembly according to claim 1 , wherein the upper step is releasably secured in the stowed position by a first releasable fastener engaging the upper movable support.

3. The assembly according to claim 2 , wherein the upper step is releasably secured in the in-use position by the first releasable fastener engaging the upper movable support.

4. The assembly according to claim 3 , wherein the lower step is releasably secured in the stowed position by a second releasable fastener engaging the lower movable support.

5. The assembly according to claim 4 , wherein the lower step is releasably secured in the in-use position by the second releasable fastener engaging the lower movable support.

6. The assembly according to claim 1 , wherein the step subassembly further comprises an upper movable support attachable to the upper step, the upper movable support pivotal between the stowed and the in-use position.

7. The assembly of claim 1 , further comprising a hinged connection interposed between the insert and the mounting bracket, the hinged connection selectively movable between the in-use position and the stowed position.

8. A collapsible stair assembly mountable to a vehicle hitch receiver for providing ease of access to a vehicle bed, the assembly comprising:

an insert releasably attachable to a vehicle hitch receiver;

a mounting bracket attached to the insert, wherein the mounting bracket is releasably attachable to a step subassembly, the mounting bracket defining multiple attachment points of varying height in relation to the vehicle bed for adjustable mounting of the step subassembly;

the step subassembly having multiple steps including an upper and a lower step, each step defining a generally planar support surface for supporting a user, each step pivotally movable between a generally vertical stowed position in which the support surface is generally vertically oriented and a generally horizontal in-use position in which the support surface is generally horizontally oriented, each step releasably secured in either the stowed or in-use position, wherein the step subassembly further comprises a lower movable support attachable to the lower step, the lower movable support pivotal between the stowed and the in-use position, wherein the lower step slidingly engages a cooperating receptacle defined in the lower movable support; and

the lower step slidably movable between a home position and an extended position, wherein the home position is relatively closer to the vehicle when the lower step is in the in-use position and the extended position is relatively further from the vehicle when the lower step is in the in-use position.
