Locking chock for tandem wheeled vehicles

A locking wheel chock to prevent the relative rotation of adjacent tandem wheels carried in alignment on spaced axles of a vehicle, comprising in combination:

• a body having an inner body tube slidably carried by an outer body tube for extensible motion relative thereto, with each outer end of each body tube having means to support at least one wheel block;
• fastening mechanism carried by the body assembly to adjustably fasten the inner and outer body tubes relative to each other, including,
• a rack, supported on the inner body tube, extending a spaced distance over the outer body tube, defining teeth on the surface distal from the inner body tube,
• a fastening bracket carried by the outer body tube, said fastening bracket having a body with similar spaced legs extending therefrom to define a channel therebetween to slidably receive the rack;
• a fastening lever supported by the fastening bracket for pivotal motion of a first end portion in the channel defined by the fastening bracket legs, said lever having a medial fastening catch and defining at the first inner end a sector of a pinion having teeth to operatively engage the teeth of the rack to move the inner body tube relative to the outer body tube responsive to pivotal motion of the fastening lever, and
• a fastening dog pivotally carried by the fastening bracket to fastenably engage the fastening catch of the fastening lever, said fastening dog being biased to fastenably engage the fastening catch but being manually movable to release the fastening catch;
• and
• at least one wheel block pivotally supported by each of the outer ends of the inner and outer body tubes to contact portions of two aligned tandem wheels above and below a line through the wheel centers to prevent relative rotation thereof.
