20100117038Foot-Operated Hydraulic Lift for Trailer - An hydraulically extensible frame is coupled to the hitch portion of a trailer by a pivoting mount. The pivoting mount permits the frame to pivot between a generally vertical operative position and a generally horizontal stowed position. A foot member is secured to an end of the frame opposite the pivoting mount. The foot member engages the ground. An actuator is carried by the frame in a location adapted to be engaged by a foot of a human user when the frame is in the operative or deployed position. The actuator pivots relative to the frame for storage and use as a handle. The actuator selectively extends the frame to raise the hitch portion in response to actuation by the foot of the user.05-13-2010
