Abstract
The present invention, in one embodiment, is a device for moving a hospital bed. The device comprises a body, a motor driven wheel coupled to the body, and a hitch coupled to the body and adapted for engaging the hospital bed. Finally, the present invention, in yet another embodiment, is a method for moving a hospital bed with a motorized device. The method comprises maneuvering the device into position next to the hospital bed, hitching the device to the hospital bed, and moving the hospital bed with the device.
Claims42
A device for assisting an operator in moving a hospital bed comprising:
- a body;
- a motor driven wheel pivotably coupled to the body, the driven wheel pivotable about a vertical axis;
- a handle pivotably coupled to the body and pivotable about said vertical axis, such that when the operator pivots the handle about the vertical axis, the driven wheel pivots about the vertical axis;
- a hitch coupled to the body and adapted for engaging the hospital bed;
- and
- a free turning wheel and a foldable arm having a first end pivotably coupled to the body and a second end coupled to the free turning wheel.
