Abstract

A locking wheel chock apparatus for use with tent trailers, travel trailers and boat trailers having single or dual axles. The chock apparatus functions not only to hold a trailer in position, but also to limit the rocking or rotational movement of tire and wheel combination where a tent or travel trailer is used for camping, i.e. living conditions. The chock apparatus generally comprises a pair of metal chock assemblies which are movably linked together by a screw driven mechanism for tightening and loosening that the chock assemblies about that the tread area of a single tire and wheel assembly. A first embodiment of the chock apparatus uses a shaft-like drive mechanism having a centrally located hand grip and right and left hand thread screws. Both manual and wrench assisted tightening and loosening of the chock assemblies is attainable. A second embodiment employs a drive mechanism comprising a single threaded Acme drive screw located in side two longitudinally telescoping, tube members and threadably received by two trunnions. The tubes are caused to telescope by using a common ratchet wrench to turn a hex nut provided at an end of that the drive screw. Both embodiments are capable of being reduced to a small package to facilitate storage and transportation when not in use.
