US 7,000,740 B2 · Combination tandem axle wheel chock and trailer tongue stand

Abstract

A pair of wheel chocks (10, 12), configured for placement under a resting tandem wheel (W) to maintain the wheel (W) at rest and for alternatively supporting a trailer tongue wheel (Wj), are disclosed. The wheel chock (10) broadly includes a body (14) that defines an internal chamber (16) in communication with an open face (18) presented by the body (14). Wheel supporting surface (26, 28) each include a arcuate leading edge (60, 62) to complement the contour of the wheel (W) and enable the chock (10) to be easily placed under the wheel (W) in an optimal position. A top surface (24) of the body (14) including an arcuate depression (32) operable to receive the trailer tongue wheel (Wj). A substantially hollow tapered supporting leg (46) projects from arcuate depression (32) for support. The top surface additionally includes an open rim (36) which can at least partially receive a supporting leg of another similar configured wheel chock (12) to enable nesting of the chocks (10, 12).

Dependent claims

A tandem wheel chock for preventing rotation of a pair of tandem wheels and for alternatively supporting a trailer tongue wheel above the ground, the chock comprising:

a first wheel supporting surface operable to be at least partially placed under one of the tandem wheels;
a second wheel supporting surface, opposed to the first wheel supporting surface, the second wheel supporting surface operable to be at least partially placed under the other one of the tandem wheels;
a pair of sidewalls connecting the first wheel supporting surface and second wheel supporting surface;
a top surface extending between the sidewalls, the top surface including a depression operable to support the trailer tongue wheel;
at least one of the surfaces including a first open rim;
and
a first substantially hollow supporting leg projecting from and being in communication with the first open rim, the first substantially hollow supporting leg being operable to support the depression above the ground,
the first wheel supporting surface extending to the top surface, and
the second wheel supporting surface extending to the top surface,
the first wheel supporting surface including a second open rim, and
the second wheel supporting surface including a third open rim.
