Abstract
A hoist for vehicles such as pickup trucks and sport utility vehicles is described. The hoist engages a standard trailer hitch and when erect allows loading of the trailer. Additionally, when used with a vehicle having a tailgate the hoist does not interfere with the normal operation of the tailgate. The hoist also features structural supports that are deployed to contact the ground thereby reducing the stress on trailer hitch and some structural members of the hoist.
Claims19
A hoist kit for a trailer hitch attachment, comprising:
- a hoist mount having a first end, a second end and a hinged joint disposed therebetween for providing rotational approximately lateral movement of the second end relative to the hinged joint when the first end is fixed, the first end for mechanically engaging the trailer hitch;
- a boom support for extending approximately vertically, said boom support for being mechanically coupled to the second end of the hoist mount;
- a boom for extending from the boom support, said boom for bearing a weight of an external load;
- and,
- a first leg for being mechanically coupled proximate the second end of the hoist mount for pivotal motion relative thereto between a first position for contacting a region of ground proximate a vehicle supporting said trailer hitch attachment and for structurally supporting the hoist mount and a second retracted position.
