Abstract
A snow rake device comprises an open shape rake head operatively coupled to a gear assembly, handle assembly, and motor. The motor drives a flex shaft to rotate, which is pinioned into a linear reciprocating motion by the gear assembly, causing the rake head to move in opposite distal and proximal directions. Cutting bars on the rake head may then break up compacted snow and ice to more efficiently clear a building roof from snow.
Claims20
A snow rake system comprising:
- a distal rake head including a plurality of cutting bars fixed to a yoke frame;
- a pinion gear assembly having a rotational input side and a linear output side, the linear output side operatively coupled to the yoke frame;
- a motor operatively coupled to the rotational input side;
- and
- a proximal handle assembly supporting the yoke frame, the pinion gear assembly and the motor.

A method for clearing snow from the roof of a building comprising the steps of:
- providing a snow rake system comprising:
- a distal rake head including a plurality of cutting bars fixed to a yoke frame;
- a pinion gear assembly having a rotational input side and a linear output side, the linear output side operatively coupled to the yoke frame;
- a motor operatively coupled to the rotational input side;

- an axle extending through the yoke frame;
- two wheels, one wheel rotatably coupled to each end of the axle;
- and
- a sheet of material coupled to and extending proximally from the axle, wherein the sheet is configured to wrap around the axle to form a sheet roll;
- assembling the snow rake system;
- placing the snow rake system near the lowest roof edge of a building;
- activating the motor;
- and
- pushing the rake head up the roof.
