Abstract
A wheel chock device arrangement to be releasably secured to a vehicle wheel, such as a trailer wheel, for temporarily encumbering the normal rotation of the vehicle wheel. The wheel chock device includes a generally triangularly shaped enclosure having a plurality of surfaces defining a substantially wedge-shaped solid with a horizontal leg, a vertical leg, and an inclined leg between the vertical and horizontal legs. A pair of closed opposed end walls enclose the legs to create the wedge-shaped solid. A generally "U"-shaped wheel-engaging jaw with telescopically engagable first and second base segments is provided, with each base segment having a leg element extending generally at right angles from the base segments, and with opposed inwardly extending stub segments extending coaxially inwardly of the leg elements of the first and second base segments. A padlock having a shackle portion arranged to be engaged by the padlock is provided, with the shackle being arranged to extend through mating bores formed in the first and second base segments of the wheel-engaging "U"-shaped jaw.
