Appl. No.:

11/201561

Inventors:

Dennis DuBois - Las Vegas NV, US

International Classification:

B65G 7/12

US Classification:

294 15, 294 271, 16422

Abstract:

A pair of devices for lifting boxes is disclosed. Each device comprises a handle, lifting surface, lifting plate and a plurality of lifting members in the form of angled teeth. During use, the teeth of each device are inserted into opposite sides of a corrugated box. A user is then able to lift the box using the temporary handles. The teeth are sized to avoid damage to the contents of the box. The teeth may be punched into a removable metallic lifting plate. The design of the teeth provides a sufficient amount of surface area for maintaining the box. During non-use the lifting plate may be removed and re-attached in an opposite orientation to prevent injuries which may be caused by the teeth.

Abstract:

A pair of devices for lifting boxes is disclosed. Each device comprises a handle, lifting surface, lifting plate and a plurality of lifting members in the form of angled teeth. During use, the teeth of each device are inserted into opposite sides of a corrugated box. A user is then able to lift the box using the temporary handles. The teeth are angled relative to a bottom edge of the lifting plates allowing a user's wrist to maintain a proper position to lift boxes over the user's head. During non-use the pair of devices they are connected with magnets such that the teeth of each lifting plate are received by corresponding openings in the other lifting plate. Each tooth may also include an extension portion for accommodating portions of a box thereby increasing the surface area of contact between the teeth and the box.

International Classification:

B65G 7/12

US Classification:

294 15, 294 271, 294 25, 16422, 16430

Abstract:

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.

US Classification:

294/015000

Abstract:

A primary carrier assembly includes a generally rectangular central frame defined by a pair of substantially parallel tubular segments joined at one ends thereof by a padded cross piece conformed for receipt in the armpit of a person and bridged proximate the other ends thereof by an offset transverse handle piece. A panel carrier assembly is releasably engaged to said other ends of said tubular segments and is defined by equally spaced, parallel posts conformed for receipt in the corresponding other ends of said tubular segments at the upper ends thereof and affixed at their lower ends to a transverse channel. The traverse piece is conformed to support panel pieces of material. In another embodiment for carrying long articles, two hangers are suspended from ends of a rod secured within said traverse channel. The primary carrier assembly can be disassembled and integrated into a conventional dolly as well.
