Abstract
An improvement for a wood stair tread of the type having a generally transparent protective coating thereon, the improvement being a three dimensional pattern formed in a top surface of the stair tread to both improve footing and preserve the natural appearance of the wood forming the top surface of the tread.
Description
- This application claims the benefit of U.S. Provisional Application No. 60/439,684 filed Jan. 13, 2003, the entire contents of which are hereby incorporated by reference.
- This invention relates to the field of stairs, more particularly, to a stair tread, which is a horizontal member which is intended to be walked upon by humans in a staircase.
- In the past, various treatments have been utilized to provide a non-skid surface to stair treads. When such treads were made of hardwood, the natural attractiveness of the wood was often desired to be displayed for aesthetic purposes. Typically, a hard, generally transparent coating was applied to allow display of the natural wood finish of the stair parts, including the tread. Such finishes included varnishes and polyurethane coatings, which performed the display function, but resulted in a stair tread that had a relatively smooth surface to walk on, and which could result in sliding or skidding as it was trod upon. Such a smooth coated surface, while providing an aesthetically pleasing surface to look at, was somewhat less desirable as a surface to walk on, particularly when a person lacked shoes or other footwear that provided a sufficient coefficient of friction to establish firm footing as the stairs were traversed.
- One solution to the slippery surface was to cover at least a central portion of the stair tread with a non-slip covering such as carpeting or adhesive-backed non-skid polymer strips. In a marine environment, it was known to add sand to varnish to provide a non-skid surface to walk on. However, each of these prior art attempts to provide a non-skid surface to a stair tread had shortcomings, particularly with respect to concealing the aesthetic appearance of the natural wood stair tread. The present invention overcomes these disadvantages by providing a non-skid treatment to a stair tread without concealing the natural appearance of a stair tread made of wood.
- FIG. 1 shows a simplified fragmentary perspective view of a staircase having stair treads useful in the practice of the present invention.
- FIG. 2 is a perspective view of a stair tread showing a first embodiment of the non-skid treatment of the present invention.
- FIG. 3 is a section view taken along line3-3 of the stair tread of FIG. 2.
- FIGS.4-27 show alternate embodiments of the non-skid treatment of the present invention.
- Referring now to the Figures, and most particularly to FIG. 1, a
staircase 10 may be seen. Staircase 10 has a plurality ofsteps 12, with each step formed by a horizontallyoriented stair tread 14 and a vertically orientedriser 16.Steps 12 may be supported by a pair ofstringers 18, (only one of which is shown in FIG. 1). Alanding tread 20 may be used at the topmost end of the staircase. - Referring now also to FIGS. 2 and 3, a
stair tread 14 formed of wood and showing one embodiment of the non-skid treatment may be seen. Tread 14 in FIGS. 2 and 3 has a threedimensional pattern 22 cut into or otherwise formed in thetop surface 24 of thetread 14. In the embodiment shown,pattern 22 is a plurality ofgrooves 26 extending from thetop surface 24 into thebody 28 of thetread 14. - It is to be understood that other forms of the three
dimensional pattern 22 may be used in thetop surface 24 of thetread 14. Providing a threedimensional pattern 22 in thetop surface 24 results in a top surface geometry that is not simply a plane surface, thus providing a somewhat texturedtop surface 24 fortread 14. This non-skid treatment results in contours in thetop surface 24 which will provide a gripping action for persons walking on thestair treads 14 to reduce the chance of slipping. At the same time the surface finish of the stair tread may still be a hard, smooth, generally transparent coating such as varnish, polyurethane or the like. Using the non-skid treatment of this invention along with one of the conventional coatings mentioned will permit the natural appearance of the wood of the tread to remain visible in an aesthetically pleasing manner, while the threedimensional pattern 22 improves the footing on the tread, and may provide an additional aesthetically pleasing design element to the appearance of the stair tread. - The invention is thus seen to be a wood stair tread having a three dimensional pattern formed in the top surface thereof. The stair tread of the present invention may be coated with a generally transparent coating covering at least the top surface of the tread to permit the natural appearance of the wood to be visible.
- Various forms of three dimensional patterns may be used in the practice of the present invention, provided that the top surface of the tread is other than a simple plane surface and improves the footing over that which would exist with a simple coated or finished plane surface.
- Referring now to FIGS. 4 through 27, alternate embodiments of the non-skid treatment of the present invention may be seen. It is to be understood that the three dimensional patterns shown in FIGS.4-27 are illustrative and not limiting, since the three dimensional pattern can take numerous forms in addition to those shown expressly herein. It is further to be understood that as used herein, “wood” for the stair tread is preferably, but not necessarily hardwood. The stair tread of the present invention may be made of wood other than hardwood, and may even be made of composite materials such as particle board or other compressed cellulose or other materials with a wood veneer for the
top surface 24 into which the threedimensional pattern 22 is formed. Thepattern 22 may be formed by saw or other machine cutting, or may be die cut when veneer is used. Alternatively,pattern 22 may be embossed or otherwise formed intop surface 24 of thetread 14. - This invention is not to be taken as limited to all of the details thereof as modifications and variations thereof may be made without departing from the spirit or scope of the invention.
Claims (5)
