Abstract
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 position. The actuator selectively extends the frame to raise the hitch portion in response to actuation by the foot of the user.
Claims20
A lift for a wheeled trailer adapted to be coupled to a vehicle by a hitch, the lift comprising:
- a frame having a foot member at one end, the foot being adapted to engage a ground surface;
- a mount secured to the frame at an end opposite the foot member, the mount for securing the frame to the trailer at a location proximal to the hitch;
- an hydraulic cylinder associated with the frame for raising and lowering at least the hitch portion of the trailer relative to the ground surface;
- an actuator coupled to the hydraulic cylinder for selectively actuating the cylinder to raise and lower the hitch portion of the trailer, the actuator being positioned and adapted to be engaged and operated by a foot of a human operator.
A lift for the hitch portion of a wheeled trailer, the lift comprising:
- a bottle jack having a cylinder and a rod, the rod being selectively extensible from an end of the cylinder responsive to actuation;
- a tubular member carried concentrically and in sliding relation about the cylinder of the bottle jack, the tubular member being secured to and movable with the rod;
- a pivoting mount securing the tubular member to the hitch portion of the trailer, the pivoting mount permitting the tubular member and bottle jack to pivot between a deployed position in which the bottle jack and tubular member extend generally perpendicular to the ground surface, and a stowed position in which the bottle jack and tubular member are generally parallel to a ground surface;
- a foot member secured to an end of the bottle jack opposite that from which the rod extends, the foot member adapted to engage the ground surface and support a portion of the trailer when the bottle jack and tubular member are in the deployed position.
A lift for selectively raising and lowering a hitch portion of a wheeled trailer, the lift comprising:
- an hydraulically extensible frame;
- a pivoting mount coupling an end of the frame to the hitch portion of the wheeled trailer, the pivoting mount permitting the frame to pivot between a generally vertical operative position and a generally horizontal stowed position;
- a wheel secured to an end of the frame opposite the pivoting mount;
- and
- an actuator 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 position, the actuator selectively extending the frame to raise the hitch portion in response to actuation by the foot of the user.
