ABSTRACT:
An apparatus for stowing or extending for loading and unloading a towing dolly. The invention comprises a vertical support stand upon which rotate a pair of spaced apart pivot arms connected to a bracket into which is placed the towing dolly. The apparatus utilizes a novel self-locking flange which rotates so as to secure the dolly within the mounting bracket when it is pivoted into the storage position, and rotates so as to release the dolly from the bracket when the device is pivoted into the load/unload position. The apparatus may be secured into the storage position by means of a spring operated latch arm and latch pin. Further, the invention provides a locking lug for locking the towing dolly into the dolly mount to prevent theft of the towing dolly.
