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).
