Abstract

Abstract Implement for snow removal includes a snow moving blade and a tubular handle of generally rectangular configuration with a cross-bar portion for manipulation of the implement. A tubular fulcrum member, of generally rectangular configuration, is pivotably carried on the back surface of the blade for pivotable movement from a retracted position generally coplanar with the handle to an angular position in which the member serves as a fulcrum. With the pivotable member disposed as a fulcrum, the implement becomes a lever for tossing snow accumulated against the front face of the blade when the implement is pushed in plow-like manner through a snow covered area. An elastic line is fastened at one end to the handle and at its other end to the fulcrum member for returning the member to its retracted position.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 125 words
Snow removal implement comprising a snow pushing blade, a handle including a cross-bar portion and leg portions affixed to the backside of said blade, said handle and blade being generally coplanar, a fulcrum member disposed between the leg portions of the handle and pivotably connected to said blade, said fulcrum being a generally rectangular frame dimensioned to fit within the handle in coplanar relation therewith, said fulcrum being pivotable for movement from and to a ground engaging position at an oblique angle to the plane of the handle and blade to and from a retracted position generally coplanar with said handle, and a retrieval line extending from the handle to said fulcrum for returning said fulcrum from its ground engaging position to its retracted position.
Claim 2
Dependent Claim 125 words
Snow removal implement comprising a snow pushing blade, a handle including a cross-bar portion and leg portions affixed to the backside of said blade, said handle and blade being generally coplanar, a fulcrum member disposed between the leg portions of the handle and pivotably connected to said blade, said fulcrum being a generally rectangular frame dimensioned to fit within the handle in coplanar relation therewith, said fulcrum being pivotable for movement from and to a ground engaging position at an oblique angle to the plane of the handle and blade to and from a retracted position generally coplanar with said handle, and a retrieval line extending from the handle to said fulcrum for returning said fulcrum from its ground engaging position to its retracted position.
Claim 3
Dependent Claim 70 words
Snow removal implement as set forth in claim 1, in which said blade is generally rectangular and said handle is a tubular member which defines with the upper edge of said blade a rectangle and said fulcrum member includes a transverse bar portion disposed parallel and contiguous to the cross-bar portion of the handle for manipulation of said fulcrum while holding said handle, said retrieval line being an elastic cord.
