Abstract

A stair tread cover suitable for covering at least one step in a staircase. The stair tread cover includes at least a front portion and a back portion. The front and back portion each have a top surface and a bottom surface. At least one friction region is optionally positioned on the bottom surface of the front portion of the stair tread cover, and at least one gripping region is optionally positioned on the top surface of the front portion of the stair tread cover.

First claim

What is claimed:

1. A stair tread cover for temporarily at least partially covering at least one step in a staircase, wherein the step includes a stair tread having a stair tread nose and a stair riser and wherein the stair tread nose extends over the stair riser, said stair tread cover comprising a sheet of material and a pre-applied position-retaining material connected to said sheet of material; said sheet of material formed of a material selected from the group consisting of paperboard, fiberboard, and cardboard; said sheet of material having a top surface, a bottom surface, a front edge, a back edge, a first side edge, and a second side edge; said sheet of material having no more than three preformed creases; said sheet of material including a first preformed crease and a second preformed crease that both extend fully between said first side edge and said second side edge; said first and second preformed creases positioned parallel to one another; said first and second preformed creases positioned parallel to said front edge and said back edge of said sheet of material; said sheet of material configured to be foldable along said first and second preformed creases; said sheet of material including a first panel, a second panel and a third panel; said second panel having a longitudinal length that extends from said front edge of said sheet of material to said first preformed crease; said third panel having a longitudinal length that extends from said back edge of said sheet of material to said second preformed creases; said second preformed crease positioned on said top surface of said sheet of material; said first panel having a longitudinal length that extends from said first preformed crease to said second preformed crease; said first and third panels configured to be foldable relative to one another; said first panel configured to be placed over a top surface of the stair tread; said second panel configured to be positioned at least partially about an outer front surface of the stair tread nose when said first panel is placed over the top surface of the stair tread and said second panel is folded downwardly along said first preformed crease; said third panel configured to be at least partially positioned over a front surface of the stair riser when said first panel is placed over the top surface of the stair tread and said third panel is folded upwardly along said second preformed crease; an angle of 60-120° exists between top planes of said first and third panels when said first panel is placed over the top surface of the stair tread and said third panel is positioned at least partially over the front surface of the stair riser and said third panel is folded upwardly along said second preformed crease; said top plane of said first panel and a top plane of said second panel in a non-planar relationship to one another when said first panel is placed over the top surface of the stair tread and said second panel is positioned at least partially about the outer front surface of the stair tread nose and said second panel is folded downwardly along said first preformed crease; said first, second and third panels having a same width; said longitudinal length of said second panel less than said longitudinal length of said first panel; said first and second panels having the same thickness; said pre-applied position-retaining material positioned on said bottom side of said sheet of material and spaced from a top side of said sheet of material, said pre-applied position-retaining material configured to facilitate in temporarily maintaining said stair tread cover in position on the step when said first panel is placed over the top surface of the stair tread, said pre-applied position-retaining material forming a removable and releasable connection with the top surface of the stair tread when said stair tread cover is positioned on the step, said pre-applied position-retaining material positioned on said first panel and is spaced from said second and third panels, said pre-applied position-retaining material extending between said first side edge and said second side edge of said sheet of material and spaced from said front edge and said back edge of said sheet of material, said sheet of material is a single sheet of material that is absent slots.

2. The stair tread cover of claim 1 , further including at least one gripping region positioned on the top surface of the front portion of the stair tread cover.

3. The stair tread cover of claim 1 , wherein the stair tread cover comprises a first sheet of material that includes the front portion and a second sheet of material that includes the back portion, the first and second sheets of material being connected together.

4. The stair tread cover of claim 1 , wherein the stair tread cover further comprises at least one reinforcement strip positioned on the top surface of the stair tread cover or bottom surface of the stair tread cover.

5. The stair tread cover of claim 1 , wherein the front portion of the stair tread cover comprises at least one portion of an increased thickness.

6. The stair tread cover of claim 1 , further comprising a plurality of stair tread covers suitable for covering the steps of the staircase.

7. A stair tread cover for temporarily at least partially covering at least one step in a staircase, wherein the step includes a stair tread having a stair tread nose and a stair riser and wherein the stair tread nose extends over the stair riser, said stair tread cover comprising a single sheet of material and a pre-applied position-retaining material connected to said sheet of material; said sheet of material formed of a material selected from the group consisting of paperboard, fiberboard, and cardboard; said sheet of material having a top surface, a bottom surface, a front edge, a back edge, a first side edge, and a second side edge; said sheet of material having no more than three preformed creases; said sheet of material including a first and a second preformed crease that both extend between said first side edge and said second side edge; said first and second preformed creases positioned parallel to one another; said sheet of material configured to be foldable along said first and second preformed creases; said sheet of material including a first panel, a second panel and a third panel; said second panel having a longitudinal length that extends from said front edge of said sheet of material to said first preformed crease; said third panel having a longitudinal length that extends from said back edge of said sheet of material to said second preformed crease; said second preformed crease positioned on said top surface of said sheet of material; said first panel having a longitudinal length that extends from said first preformed crease to said second preformed crease; said first and third panels configured to be foldable relative to one another; said first panel configured to be placed over a top surface of the stair tread; said second panel configured to be positioned at least partially about an outer front surface of the stair tread nose when said first panel is placed over the top surface of the stair tread and said second panel is folded downwardly along said first preformed crease; said third panel configured to be positioned at least partially over a front surface of the stair riser when said first panel is placed over the top surface of the stair tread and said third panel is folded upwardly along said second preformed crease; an angle of 60-120° exists between top planes of said first and third panels when said first panel is placed over the front surface of the stair tread and said third panel is positioned at least partially over the top surface of the stair riser and said third panel is folded upwardly along said second preformed crease; said
