ABSTRACT:
The present invention relates to a hitching device designed to be used to detachably connect two vehicles together. The hitching mechanism includes two jaws which may pivot with respect to one another in a controlled manner by virtue of intermeshing gearing therebetween. The ends of the jaws have a complimentary tongue and groove connection to facilitate resistance of forces which would tend to separate the jaws in the absence thereof. A lock block is provided to control locking and unlocking of the jaws, while a safety pin is provided to protect against undesired jaw movements.
