  • Patent number: 5346357
    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.

  • Patent number: 5209628
    Abstract: An apparatus for stowing and extending for removal a towing dolly used for towing automotive vehicles. The apparatus is formed from a generally vertical support stand which is secured to the bed of a towing vehicle. Pivotally connected to the support stand is a first arm having a range of motion extending from a near vertical storage position to a near horizontal load/unload position. Pivotally attached to the first arm is a second arm which is in a near vertical position during loading and remains in a near vertical position as the first arm is pivoted into the storage position, such that the two arms are now nearly parallel. This relationship is maintained by a gas spring pivotally connected to the support stand and the second arm such that the gas spring maintains a generally parallel configuration with the first arm. A dolly mount is attached to the end of the second arm for releasably securing a towing dolly to the vertical arm.
