Abstract
A tool for measuring, marking, or cutting material, the tool formed of a rigid sheet of transparent material having a plurality of lines formed thereon, and a transparent, non-removable, slip-resistant coating applied to a working surface of the rigid sheet to resist slipping of the tool when applied to the material.
Claims33
A device for use in measuring material, comprising:
- a transparent substrate of rigid material having a plurality of lines formed thereon;
- and
- a transparent, non-removable coating on a working surface of the transparent substrate of rigid material, the coating configured to resist slipping of the device on the material to be measured.
A method making a device for use in measuring material, comprising:
- providing a substrate of rigid material;
- forming a plurality of lines on the substrate;
- and
- applying a transparent coating to at least a portion of a working surface of the substrate to provide a non-slip bearing surface when placed on the material to be measured.
A method of making a device for use in measuring, marking, and cutting material, the method comprising:
- providing a transparent substrate having a plurality of composite lines, each composite line formed of at least two lines of contrasting colors to enhance visibility of the composite line;
- and
- applying a transparent, non-removable substance on at least a portion of a surface of the transparent substrate, the substance having a high coefficient of friction with respect to the material to resist slipping of the substrate on the material.
A tool, comprising:
- a transparent substrate having a plurality of opaque lines formed on at least one surface thereof;
- a plurality of composite lines formed of a first line of a first color and a second line of a second color that contrasts with the first color to form composite lines of enhanced visibility, the composite lines formed of a pigment that enhances the visibility of the composite lines in a low-light condition;
- and
- a transparent, non-removable substance applied to the transparent substrate, the substance configured to resist slipping of the tool.
A tool for measuring and marking material and for guiding a hand-held cutting tool, comprising:
- a transparent substrate having mutually-opposing planar front and back surfaces and formed of a thickness that is adapted to guide a hand-cutting tool;
- a least one composite line formed on one of the front and back surfaces of the transparent substrate, the composite line formed of at least first and second lines of contrasting color;
- and
- a transparent, non-slip, non-removable substance applied on the transparent substrate to provide a non-slip surface that resists slipping of the transparent substrate on the material.
A tool for measuring and marking material and for guiding a hand-held cutting tool, comprising:
- a transparent substrate having mutually-opposing planar front and back surfaces and formed of a thickness that is adapted to guide the hand-held rotary cutting tool;
- and
- a plurality of lines formed on one of the front and back surfaces of the transparent substrate, at least one of the plurality of lines formed of a non-removable substance having a high coefficient of friction to resist slipping when the tool is applied to the material, the substance adapted to not attract dust or lint or the material.
