Abstract

Abstract An open-ended snow scoop or bucket with a convex ground engaging surface is pivotally connected between a pair of mounting arms which extend forwardly from a curved frame. The bucket is pivoted about an axis behind its center of gravity so that when the frame is rocked back and forth, the bucket will pivot between a loading position in which snow can be scooped up by the bucket and a dumping position in which snow will be dumped from the bucket. A pair of handles extend upwardly and rearwardly from the curved portion of the frame, each handle being pivoted to the frame about a substantially vertical axis. Latch members are attached to the bottom of the handles and contact latch arms which project rearwardly from the bucket for normally latching the bucket in its loading position. The bucket can be unlatched to free it for movement to the dumping position by rotating the handles outwardly and forwardly to a frontal position in which the frame can be conveniently rocked back to cause the bucket to pivot to its dumping position. The movement of the bucket toward its dumping position is limited by an expansion spring connected between the frame and the back of the bucket. The spring causes the bucket to oscillate about its dumping position to help shake the snow therein loose for dumping.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 161 words
A snow scoop comprising a frame which includes a curved portion that can be rocked on an underlying surface, a pair of mounting arms extending forwardly from said curved portion, an open ended bucket pivotally connected between said mounting arms on a pivotal axis which lies behind the bucket''s center of gravity, whereby rocking of said frame on the curved portion thereof causes said bucket to pivot between a loading position in which snow can be scooped up by said bucket and a dumping position in which snow will be dumped from said bucket, a pair of handles vertically pivotally attached to said frame and pivotable between a rear position and a frontal position, and cooperating latch means attached to said handles and said bucket for latching said bucket in its loading position when said handles are in their rear position and for unlatching said bucket for movement to its dumping position when said handles are moved to their frontal position.
Claim 2
Dependent Claim 161 words
A snow scoop comprising a frame which includes a curved portion that can be rocked on an underlying surface, a pair of mounting arms extending forwardly from said curved portion, an open ended bucket pivotally connected between said mounting arms on a pivotal axis which lies behind the bucket''s center of gravity, whereby rocking of said frame on the curved portion thereof causes said bucket to pivot between a loading position in which snow can be scooped up by said bucket and a dumping position in which snow will be dumped from said bucket, a pair of handles vertically pivotally attached to said frame and pivotable between a rear position and a frontal position, and cooperating latch means attached to said handles and said bucket for latching said bucket in its loading position when said handles are in their rear position and for unlatching said bucket for movement to its dumping position when said handles are moved to their frontal position.
Claim 3
Dependent Claim 27 words
The snow scoop of claim 1 and further comprising a convex dish attached to the bottom of said bucket to serve as a low friction support therefore.
Claim 4
Dependent Claim 47 words
The snow scoop of claim 1 and further comprising an expansion spring connected between said bucket and said frame for limiting the movement of said bucket toward its dumping position to cause said bucket to oscillate about its dumping position to help shake loose the snow therein.
Claim 5
Dependent Claim 45 words
The snow scoop of claim 1 wherein said frame includes a pair of upstanding tubular side members, and wherein said handles include vertical portions which are pivotally contained within the interior of said side members and are pivotable about the axis of said side members.
Claim 6
Dependent Claim 70 words
The snow scoop of claim 4 wherein said latch means includes a pair of latch pins projecting transversely from the vertical portions of said handles and a pair of latch arms attached to the back of said bucket and positioned to abut against said latch pins when said bucket is in its loading position and said handles are in their rear position to latch said bucket in its loading position.
Claim 7
Dependent Claim 68 words
The snow scoop of claim 5 wherein said frame includes a cross brace attached to the tops of said side members and extending therebetween, and a stop member attached to each latch pin and extending downwardly therefrom to abut against said cross brace when said handles are in their rear position and frontal position to limit the rotation of said handles toward their rear position and frontal positions.
Claim 8
Dependent Claim 24 words
The snow scoop of claim 4 wherein said side members are curved at a 90* angle and extend forwardly to form said mounting arms.
Claim 9
Dependent Claim 34 words
The snow scoop of claim 7 and further comprising upwardly curved runners attached to the bottom of said mounting arms, the curved portion of said runners underlying the curved portion of said side members.
