Mobile loading dock with adjustable leg assembly

1. An adjustable leg assembly for a mobile loading dock comprising:

an elongate, adjustable housing including incremental slots;

a compression spring within the housing;

a lock bracket for insertion into the slots to contact and hold the spring in place; and

a baseplate for contact with the ground;

whereby the user removes the bracket from the slots allowing the spring to compress which shortens the length of the adjustable housing allowing movement of the loading dock to a different location.

2. The leg assembly of claim 1 wherein each loading dock includes two leg assemblies.

3. The leg assembly of claim 1 further including a button on the lock bracket for securing the bracket in place during ramp movement.

4. The leg assembly of claim 1 wherein the housing has a top end and a bottom end, the top end connected to a ramp portion of the loading dock and the bottom end connected to a baseplate in contact with the ground when the dock is in a non-mobile position.

5. The leg assembly of claim 1 wherein the loading dock includes (a) a first upper-end planar portion, the plane of which is parallel to a ground surface on which a ramp member rests; and (b) a second planar portion, the plane of which is downwardly-angled from an upper end to a lower edge.

6. The leg assembly of claim 5 wherein the ramp member includes two leg assemblies, the leg assemblies being equally distant from a point on the lower edge.

7. The leg assembly of claim 1 wherein the lock bracket is tethered to the housing in both an inserted and uninserted position.

8. A method of raising and lowering an adjustable leg assembly for a mobile loading dock the method comprising:

providing (a) an elongate, adjustable housing in a resting position and including incremental slots; (b) a compression spring within the housing; (c) a lock bracket inserted into the slots to contact and hold the spring in place; and (d) a baseplate for contact with the ground;

placing a user's foot on the baseplate;

removing the lock bracket from the slots causing the adjustable leg to shorten in length and to raise upward from the resting position;

removing the user's foot from the baseplate;

moving the ramp member to the new, desired position;

placing the user's foot on the baseplate and pushing downward toward the ground; and

placing the lock bracket into the slots when the leg assembly reaches the desired height.
