Claims
- 1. A handle mechanism for an object to be lifted, comprising:
- a substantially vertical support shaft having a substantially horizontal hand piece extending from one side of the top of the vertical support shaft;
- a pin member extending a short distance outwardly from the side of the bottom end of the vertical support shaft opposite the side thereof from which said hand piece extends;
- upper bracket means for attachment to a substantially vertical side of an object to be lifted and for maintaining said support shaft in substantially vertical position, said upper bracket means having an opening through which said support shaft passes, said opening being sufficiently small to maintain said shaft in substantially vertical position, but still permit said shaft to rotate within said opening, said upper bracket means being of sufficient strength to permit lifting of an object when said handle member is raised to that the pin at the lower end of the shaft stops in engagement with the lower surface of the upper bracket means for transmitting lifting force through said handle to an object to which said upper bracket means is attached;
- lower stop bracket means for limiting downward movement of the support shaft;
- wherein said lower stop bracket includes a top surface which slopes downwardly from one side to the other of said lower stop bracket forming an incline plane upon which the pin in the bottom of the vertical shaft can travel functioning as a camfollower for orienting the rotation of the vertical shaft in a direction wherein the handpiece is directed substantially parallel to the side of the object to which the handle means is to be attached.
- 2. The handle apparatus of claim 1 wherein said lower bracket comprises a generally U-shaped cross section having substantial flange portions extending laterally from the top of each vertical arm of the U, said flange portions for attachment to an object to be lifted by the handle, and the top surface of the lower stop bracket forms a partial spiral surface for following by the pin in the bottom of the vertical handle member.
