Abstract
A roller supported scoop shovel is pivotally mounted on a forward portion of a wheeled mobile frame having generally upright handle means. Control of the shovel for material scooping, lifting, transporting, pushing and dumping modes is effected by means adapted to be manipulated adjacent to the top of the handle means. The frame is adapted to be rocked to facilitate operation of the shovel. All operations of the shovel including material scooping, lifting, pushing and dumping are adapted to be effected by a person remaining substantially erect. The device is readily collapsible for storage.
Claims29
A manually operable shovelling and dumping device especially adapted, for snow removal and the like, comprising:
- a scoop shovel having a front scooping edge;
- a mobile frame having generally upright handle means;
- wheel means mounting said frame adjacent to the lower end of said handle means;
- means including horizontal shaft means pivotally mounting said scoop shovel on a front end portion of said frame and which extends forwardly from said wheel means for pivoting of said scoop shovel about the horizontal axis of said shaft means between scooping and dumping positions relative to said frame;
- means adapted to be manipulated near the top of said handle means for controlling said scoop shovel in respect to said scooping and dumping positions;
- said wheel means permitting rocking of said frame by manipulation of said handle to raise said forwardly extending portion of said frame to facilitate pivoting of said scoop shovel between said scooping and dumping positions;
- and anti-friction roller means rotatably carried by said shaft means and supporting the scoop shovel against contact rearwardly from said scooping edge with an underlying surface over which the device is operated;
- all of said means being cooperatively related to permit operation of the device with minimal effort by a person remaining substantially erect throughout a full range of scooping and dumping maneuvers of the device.
A manually operable shovelling and dumping device especially adapted for snow removal and the like, comprising:
- a scoop shovel having a front scooping edge;
- a mobile frame for maneuvering said scoop shovel, said frame having generally upright handle means having wheel means at its lower end;
- a forward frame extension having rear pivot means connecting it to the lower end of said handle means and projecting forwardly from said handle means and having front pivot means connecting it to said shovel;
- means for controlling the upstanding attitude of said handle means relative to said forward frame extension comprising a diagonal brace structure having a first portion pivotally connected, on a common axis with said front pivot means, to said forward portion of said frame extension and a second portion pivotally connected to said handle means substantially above said rear pivot means;
- and means connecting the first and second portions for selective longitudinal adjustment for effecting pivotal adjustments of the handle means relative to said frame extension.
A manually operable shovelling and dumping device especially adapted for snow removal and the like, comprising:
- a scoop shovel having a front scooping edge;
- a mobile frame having generally upright handle means;
- means pivotally mounting said scoop shovel on a portion of said frame extending forwardly from the lower end of said handle means;
- wheel means mounting said lower end of said handle means and including a horizontal shaft;
- means for controlling said shovel between scooping and dumping positions relative to said forwardly extending portion of said frame and comprising an elongate structure having a rear end portion at said shaft and projecting forwardly to means connecting a front end portion of said structure to a rear portion of said shovel;
- and actuating means extending downwardly from adjacent to the top of said handle means and connected to said rear end portion of said structure;
- said actuating means being operable from adjacent to to top of said handle means for actuating said structure for said controlling of said shovel.
A manually operable shovelling and dumping device especially adapted for snow removal and the like, comprising:
- a scoop shovel having a front scooping edge;
- a mobile frame having generally upright handle means;
- means pivotally mounting said scoop shovel on a portion of said frame extending forwardly from the lower end of said handle means;
- wheel means mounting said lower end of said handle means and including a horizontal shaft;
- means for controlling said shovel between scooping and dumping positions relative to said forwardly extending portion of said frame and comprising an extension from said shaft to said shovel and operable from adjacent to the top of said handle means;
- said controlling means comprise a latch member extending from said shovel to said shaft;
- and keeper means carried by said shaft and cooperating with said latch member.
