An improved vehicle locking wheel chock comprising a pair of wedge shaped chocks having flat bottom ground contacting surfaces each rigidly affixed to respective end portions of a spacing bar with the chock bottom surfaces in a coplanar relationship and the oblique wedge surfaces of the respective chocks in a facing relationship spaced apart a distance that the space between the respective chock oblique wedge surfaces defines the region occupied by the vehicle wheel and tire. Each chock rotatably supports a lockable retaining mechanism comprising a support rod extending transversely of the chock with a pair of elongated retaining arms rigidly affixed to opposite ends of the rod to extend transversely of the rod axis and spaced apart a distance exceeding the width of a vehicle wheel and tire. Each rod is pivotally supported by a chock for rotation about the longitudinal axis of the rod between an open position in which both retaining arms lie outside the face of the wheel region space defined between the oblique wedge surfaces of the respective chocks and a closed position in which both retaining arms lie across the face of the wheel region space defined between the oblique wedge surfaces of the respective chocks. The outer ends of the retaining arms of both retaining mechanisms positioned on the same side of the pair of chocks being configured for being mutually coupled together when the retaining arms are in the closed position.

A vehicle wheel locking chock comprising a pair of wedge shaped chocks each having a bottom surface adapted to rest on the ground and from a pointed forward end of which a vertically oblique wedge surface adapted to contact the perimeter of a vehicle tire extends rearwardly between chock side surfaces to an upper portion of the rear end surface of the chock, spacing bar means affixed to each said chock for interconnecting said pair of chocks with said chock bottom surfaces in a substantially coplanar relationship and the respective oblique wedge surfaces of said pair of chocks in a facing relationship spaced apart at a distance such that the space between said respective chock wedge surfaces defines a region to be occupied by a lower portion of a vehicle tire, an elongated support rod extending transversely of each chock between said side surfaces, first and second elongated arms rigidly affixed to opposite ends of each said support rod exteriorly of a chock side surface to extend outwardly and transversely of the longitudinal axis of said rod, and means rotatably supporting each said rod for rotation about its longitudinal axis between an open position in which said first and second arms extend outside the face of said space between said chock oblique wedge surfaces defining said tire region and a closed position in which said first and second arms extend across the face of said space between said chock oblique wedge surfaces defining said tire region.
