发明名称 Box lifting devices
摘要 A box lifting device places weight upon the lateral surface of lifter's forearm or hand. Preferred embodiments include a lifting body and a handle molded as a single piece of injection molded plastic, a lifting plate having metal teeth or other lifting members, and a weight transfer member that shifts the weight of a box to a lateral surface of the users forearm or hand. The lifting members are preferably angled other than 90° relative to a long axis of the handle. Preferred lifting plates include a plurality of openings, such that the lifting members of one plate enter the openings in the other plate and vice versa during storage of the devices. Magnets can be included to couple the left and right mating pairs. Lateral and medial forearm stops can be used to restrict a bending movement of the user's wrists relative to the handle.
