Abstract

A tool and method for removing a film from a surface is provided, wherein the tool can include a frame, a handle operably coupled to the frame, a number of wheels operably coupled to the frame, a cylinder rotatably coupled to the frame, an arm rotatably coupled to the frame, and a number of separating devices operably coupled to the arm. In some embodiments, the wheels can rotate about one or more axes parallel to the surface. The cylinder, which collects the removed film, rotates about an axis that can also be parallel to the surface. The arm can rotate about an axis that can also be parallel to the surface.

Claims (22)

1. A tool for removing a film from a surface, comprising:

a frame;

a handle coupled to the frame;

at least one lever pivotably attached to the handle;

a plurality of wheels coupled to the frame, each of the wheels rotatable about a respective axis;

an arm rotatably coupled to the frame;

a cylinder rotatably coupled to the arm and positioned to collect film from the surface by winding the film completely about the cylinder more than one time; and

at least one blade coupled to the frame and movable into contact with the surface, wherein the blade is coupled to the at least one lever such that moving the at least one lever changes the position of the blade relative to the surface.

2. The tool of claim 1 , wherein the cylinder has a sleeve disposed thereon, and wherein the sleeve comprises at least one of a rigid tube, plastic film, and paper.

3. The tool of claim 1 , wherein the blade is removably coupled to the frame by a base.

4. The tool of claim 3 , wherein the base comprises a resiliently flexible material.

5. A tool for removing a film from a surface, comprising:

a frame;

a handle coupled to the frame;

at least one lever pivotably attached to the handle;

a plurality of wheels coupled to the frame, each of the wheels rotatable about a respective axis;

an arm rotatably coupled to the frame;

a cylinder rotatably coupled to the arm and positioned to collect film from the surface; and

at least one blade coupled to the frame and movable into contact with the surface, the blade resiliently biased in a downward direction to engage the film, wherein the blade is coupled to the at least one lever such that moving the at least one lever changes the position of the blade relative to the surface.

6. The tool of claim 5 , further comprising a spring operably coupled to the arm and the frame, the spring positioned to bias the arm toward the surface.

7. The tool of claim 5 , wherein the base comprises a resiliently flexible material.

8. The tool of claim 7 , further comprising a weight attached to the base, wherein the weight applies pressure to the blade.
