Abstract
Apparatus is disclosed for removing snow from an inclined surface such as a structural roof, including an elongated flexible sheet having a low surface coefficient of friction, and adapted for sliding along the inclined surface, the sheet being attached to a rod and the rod having an attachment for propelling the apparatus.
Claims19
An apparatus for sliding snow from a roof;
- comprising
- a. a rectangular plastic slide having a length dimension substantially longer than its width dimension, said length dimension forming an elongated slide along the surface of said roof which may overhang the edge of said roof;
- b. an edge support rod attached along a width dimension edge of said rectangular slide;
- c. a U-bracket having snow-cutting legs attached to said edge support rod;
- and
- d. an elongated pole attached to said U-bracket in spaced alignment with said plastic slide length dimension.
An apparatus for removing snow from a surface, comprising:
- a. a rectangular sheet of plastic material having a length dimension substantially longer than its width dimension;
- b. an edge support rod attached along each width dimension end of said rectangular sheet;
- c. support means attached to each edge support rod for supporting said rod in spaced and slidable relationship to said surface;
- and
- d. an elongated rope attached to each of said edge support rods.
An apparatus for removing snow from an inclined roof surface, comprising:
- a. a U-frame having two substantially vertical and parallel snow cutting arms, and having means for attaching a handle thereto;
- b. a snow cutting bar extending between said snow cutting arms;
- c. a sheet of flexible slide material attached to said snow cutting bar;
- d. transport means, attached to said snow cutting arms, for low-friction travel contact of said frame over said inclined surface;
- and
- e. an elongated handle connected at one of its ends to said U-frame means for attaching a handle.
An apparatus for removing snow from an inclined roof surface by cutting the snow into rectangular blocks and sliding said snow over the inclined surface, comprising:
- a. a sheet of flexible material having a long dimension and a short dimension, and having a smooth texture;
- b. an edge support rod attached along a short dimension of said sheet;
- c. means for supporting said edge support rod in spaced relationship to said surface;
- and
- d. means for propelling said sheet over said inclined surface, attached to said edge support rod, and comprising a frame member having vertical snow cutting edges and an elongated handle attached thereto.
An apparatus for removing snow from a roof surface, comprising:
- a. a sheet of flexible material having a long dimension for forming a slide along said roof surface and a short dimension for undercutting said snow, and having a surface coefficient of friction of less than 0.2;
- b. an edge support rod attached along a short dimension edge of said sheet;
- c. a pair of wheels attached to said edge support rod;
- d. a U-bracket having snow-cutting legs attached proximate the ends of said edge support rod adjacent said wheels;
- and
- e. an elongated pole attached to said U-bracket in alignment with said sheet long dimension and in approximate perpendicular relationship to said U-bracket.
An apparatus for removing snow from a roof surface, comprising:
- a. a sheet of flexible material having a long dimension and a short dimension, and having a smooth texture;
- b. an edge support rod attached along a short side of said sheet and a second edge support rod attached along a second short side of said sheet;
- c. a pair of wheels attached to each of said edge support rods;
- and
- d. a cord loop attached to each of said edge support rods.
An apparatus for removing snow from a roof surface, comprising:
- a. a sheet of flexible material having a long dimension and a short dimension, and having a surface coefficient of friction of less than 0.2;
- b. an edge support rod attached along a short side of said sheet, and a second edge support rod attached along a second short side of said sheet;
- c. a pair of wheels attached to each of said edge support rods;
- and
- d. a cord loop attached to each of said edge support rods.
