carpet stair protector in JOSEPHINE.Field of the invention this invention relates to stair noses and especially to stair noses of substantially clear plastic which are adapted to be placed over the forward edges or noses of carpeted stairs.
Description of the prior art it is well known to protect the carpeting on a flight of stairs by placing a plurality of transparent plastic protectors over at least the nose of each step, i.
Furthermore, it is known to secure such protectors to the carpet by using downwardly depending ribs integral with the step portion of the protector.
This type of stair step carpet protector is called tackless because no tacks are used with the protector itself.
However, even in this type a separate member is needed which is secured to the step by tacks driven through the carpeting and into the underlying step and is then interlocked with the protector.
Of course, such an arrangement produces damaging holes in both the carpet which it was supposedly protecting as well as underlying stairs.
In order to overcome the disadvantages of the prior art outlined above the applicant has provided a truly tackless carpeted stairstep protector.
The stair portion also has serrations formed upon its upper surface for improved footing and a plurality of downwardly depending sharpened cleats which point towards the riser portion.
These serrations may have any suitable pattern.
The cleats grip the carpet and resist the tendency of the stair step protector to slip forward when a person steps thereupon.
The same elements are designated by the same reference numerals throughout the drawings.
Referring to the drawings, a tackless stair carpet protector 10 is shown to be comprised of an integral piece of material.
Preferably, this material is a transparent or translucent plastic which allows the color of the underlying carpet to be seen.
Protector 10 has a riser portion 12, a nose portion 14 and a step portion 16 each of which is designed to tightly engage the riser, nose and step portions of a carpeted stairstep.
The riser and nose portions 12 and 14, respectively, and the step portion 16 have a substantially uniform thickness.
The cleats 18 may have the form shown in fig.
In either case, the cleats are arranged in parallel rows as illustrated in figs.
Of course, the rigidity of nose and riser portions 14 and 12, respectively, also resists any forces attempting to remove teeth 18 from the carpet.
If necessary to insure appropriate springing action, the nose portion 14 may be thicker than the step and riser portions 16 and 12, respectively, and this modification is shown in fig.
The top of step portion 18 contains a plurality of serrations 20 to improve the frictional qualities of step portion 16.
A straight line pattern is shown in fig.
Also, the serrations may be molded into step portion 18 or may be added after molding as by score lines.
As can best be seen from fig.
As may be seen from fig.
Thus, the carpet tread 10 may be easily modified to fit a narrower step merely by cutting along the appropriate score line.
Of course, more than the two score lines shown in fig.
Thus, the following claims must be referred to to determine the proper scope of the invention.
