ABSTRACT:
A utility hand cart is disclosed which is particularly suited for use in lifting and transporting bulky heavy objects, such as automobile transmissions, air conditioner compressors, etc. The cart comprises a lower U-shaped rectangular frame and an elongated inverted U-shaped handle having its lower open ends pivotally attached to each side of the lower frame. Wheels are rotatably mounted on a bracket beneath each side of the handle and move therewith to engage the lower frame member. In use, the cart is wheeled into position and the handle is raised to pivot the front end of the lower frame about the wheel axis to contact the floor surface and the front of the lower frame is slid beneath the object to be lifted. When properly positioned, the handle is raised further causing the wheel to pivot upwardly relative to the lower frame until the lower frame is resting horizontally on the floor. When the handle is released, a spring returns the handle to the lower position and the wheel axle engages the lower frame. To lift the object, the handle is pushed down and the object is lifted and transported to another location. After transporting the object, the handle is again lifted moving the lower frame to the floor, gently placing the lifted object on the floor surface.
