Abstract

A self-loading tool 2 for removing snow 10 from a surface 12 includes a blade 4 attached to a handle 6. Handle 6 is attached to a neutral plane 24 of blade 4 at an angle between about 65° to about 85° and preferably about 75°. This angle of attachment between handle and blade permits the blade to be self-loading when pushing or when pulling snow across a surface. An apparatus and a method are disclosed.

Claims

1. A hand operated self-loading tool for removing snow from a surface by pushing and pulling the tool, comprising:

a blade including first and second faces, and first and second spaced apart edges, each edge defining a substantially rounded cross-section, the blade defining a neutral plane;

a handle attached to the first face, at an angle of about 65°

to about 85°

with respect to the neutral plane;

the handle permitting a suer to push or pull the blade to remove snow from the surface, the second face pushing the snow when the second edge is opposite the surface, the first face pulling the snow when the first edge is opposite the surface;

said angle between the handle and the blade causing the snow being removed to press against the second face and maintain the second edge of the blade opposite the surface while pushing the tool when the handle is substantially parallel to the surface, and said angle causing the snow being removed to press against the first face and maintain the first edge of the blade opposite the surface while pulling the tool when the handle is substantially parallel to the surface.

2. The hand operated tool of claim 1, wherein the blade is substantially flat.

3. The hand operated tool of claim 1, wherein said angle is about 75°

.

4. The hand operated tool of claim 1, wherein the handle is attached to the first face towards the second edge.

5. The hand operated tool of claim 1, wherein the first and second edges substantially conform to the surface from which snow is to be removed.

6. The hand operated tool of claim 1, wherein the handle is elongated.

7. A hand operated self-loading tool for removing snow from a surface by pushing and pulling the tool, comprising:

a blade including first and second faces, and first and second spaced apart edges, each edge defining a substantially rounded cross-section, the blade sized top remove snow and defining a neutral plane;

an elongated handle attached to the first face towards the second edge, at an angle of about 75°

with respect to the neutral plane;

the handle permitting a user to push or pull the blade to remove snow from the surface, the second face pushing the snow when the second edge is opposite the surface, the first face pulling he snow when the first edge is opposite the surface;

said angle between the handle and the blade causing the snow being removed to press against the second face and maintain the second edge of the blade opposite the surface while pushing the tool when the handle is substantially parallel to the surface, and said angle causing the snow being removed to press against the first face and maintain the first edge of the blade opposite the surface while pulling the tool when the handle is substantially parallel to the surface.

8. A method of removing snow from a surface with a self-loading hand operated tool, comprising the following steps:

selecting a tool with a blade and a handle, the blade sized to remove snow and defining a neutral blade plane, the blade including first and second faces and first and second spaced apart edges, the handle attached to the first face of the blade at an angle of about 65°

to about 85°

with respect to the neutral blade plane;

resting the second edge on the surface and then pushing the second face into the snow to push the snow over the surface;

resting the fist edge on the surface and then pulling the first face toward the snow to pull the snow over the surface;

said angle between the handle and the blade causing the snow being removed to press against the second face and maintain the second edge in contact with the surface while pushing the tool when the handle is substantially parallel to the surface, and said angle causing the snow being removed to press against the first face and maintain the first edge in contact with the surface while pulling the tool when the handle is substantially parallel to the surface.

9. The method of claim 8, wherein the step of selecting a tool includes selecting a blade whose first and second edges substantially conform to the surface from which snow is to be removed.

10. The method of claim 8, wherein the step of selecting a tool includes selecting a blade with first and second edges each defining a substantially rounded cross-section.

11. The method of claim 8, wherein the step of selecting is carried out using a handle attached to the blade at an angle of about 75°
