Abstract

A shovel includes an elongated cylindrical shaft having a shovel blade removably secured by a pin and socket connection at a first end, and a first D-shaped hand grip at a second opposite end. A split cylindrical clamping collar includes a clamping screw for securing the collar at a selected position around the shaft. A lateral extension member is pivotally mounted to the clamping collar for movement about an axis which extends parallel to a longitudinal axis of the shaft. A second D-shaped hand grip is secured on a free end portion of the extension member. In use, an individual grasps one of the hand grips in each hand and rotates the first hand grip while holding the second hand grip secured to the lateral extension member stationary, to dump the contents of the shovel blade. The shovel handle construction is particularly adapted for use on snow shovels, and allows an individual to work with a minimum of effort and back strain.

Claims6

Dependent claims

A shovel, comprising:

an elongated shaft having first and second opposite ends;
means securing a shovel blade at said first end of said shaft;
a first hand grip at said second end of said shaft, said first hand grip including a first linear bar extending perpendicular to said elongated shaft;
a pair of split cylindrical collars;
fastening means securing said split cylindrical collars in axially spaced, frictional engagement around said elongated shaft in a selected adjustable axial position on said shaft;
a lateral extension member extending perpendicular to said elongated shaft between said split cylindrical collars;
a second hand grip on said lateral extension member, said second hand grip including a second linear bar extending perpendicular to said elongated shaft and said lateral extension member;
and
a pivot pin extending between said split cylindrical collars and transversely through said lateral extension member, said pivot pin pivotally mounting said lateral extension member for selective movement in either opposite rotational direction about a pivot axis parallel to longitudinal axes of said shaft and said split cylindrical collars and constraining said lateral extension member from pivotal movement about axes oblique and perpendicular to said longitudinal axes of said shaft and split cylindrical collars, said pivot axis lying in a plane perpendicularly bisecting said elongated shaft, said first and second linear bars and said shovel blade.
