Abstract
A wheel chock for restraining motor vehicles during transport comprises a monolithic body defined by a synthetic plastic molding or an aluminum casting and provided with a pair of locking pins and a latching mechanism for releasably securing it to a mounting rail fixed on a deck of the vehicle transporter. The chock also incorporates a reeling mechanism, including a pawl and ratchet locking device, for holding and tensioning an over-the-wheel safety harness.
Claims23
A wheel chock for use on a motor vehicle transporter for releasable attachment to an elongated restraining element affixed to the transporter and having a pair of upright walls, at least one of which contains a longitudinal series of uniformly spaced and sized holes, the chock comprising.
- a. an elongated, monolithic body formed with a central ridge wall flanked by a pair of downward sloping, wheel-engaging side wall portions arranged symmetrically with respect to the ridge wall, and with a transverse, open bottom recess adapted to receive the restraining element and bounded at one side by a transverse web;
- and
- b. a pair of locking pins fixed to the body, projecting into the transverse recess from the transverse web, and being arranged to engage in alternate holes in the restraining element,
- c. the recess containing an unobstructed space beyond the ends of the pins slightly wider than the restraining element, whereby the body may be placed on that element from above and then shifted in the direction of its length to bring the pins into engagement with said holes, and
- d. the body being tiltable in both horizontal and vertical planes with respect to the restraining element when the pins are engaged in said openings, but the magnitude of such tilting being limited by the margins of the recess so that at least one of the pins always remains engaged in its associated hole.
A wheel chock for use on a motor vehicle transporter for releasable attachment to an elongated restraining element affixed to the transporter and having a pair of upright walls, at least one of which contains a longitudinal series of uniformly spaced and sized holes, the chock comprising
- a. an elongated body formed with a transverse, open bottom recess for receiving the restraining element and being bounded at one side by a transverse wall;
- b. a pair of locking pins carried by the body, projecting into the recess from the transverse wall, and being arranged to engage in alternate holes in the restraining element;
- c. a transverse latching member mounted for pivotal movement on the body at the side of the recess opposite the transverse wall so it may be swung into and out of the recess when the body is on the restraining element and the pins are engaged in holes in that element,
- d. the latching member having a latching position, in which it is disposed in the recess along one of the upright walls of the restraining element and coacts with the transverse body wall to limit movement of the body in its longitudinal direction and prevent withdrawal of the pins from their associated holes;
- and
- e. a manually releasable locking means for selectively holding the latching member in latching position.
A wheel chock for use on a motor vehicle transporter for releasable attachment to an elongated restraining element affixed to the transporter and having a pair of upright walls, at least one of which contains a longitudinal series of uniformly spaced and sized holes, the chock comprising a monolithic, elongated, open bottom body having
- a. a transverse wall across one end;
- b. a central ridge wall extending longitudinally along the top of the body and including a first wall portion adjacent the transverse wall, a second wall portion adjacent the opposite end, and an intermediate third wall portion which encompasses an elongated window opening;
- c. a pair of side walls comprising symmetrical, sloping wheel-engaging surfaces which extend outward and downward from the ridge wall and each of which joins a depending, substantially vertical surface;
- d. four transverse webs interconnecting the side and ridge walls, one web being located at each end of the third ridge wall portion and the other two webs being located intermediate the ends of the first ridge wall portion;
- and
- e. a pair of aligned openings extending through the vertical surfaces of the side walls and sized to receive the restraining element, these openings being located between said other two transverse webs.
