CARPET FASTENING DEVICE Filed July 1, 1968 INVENTOR F's 3 JAMES L. DIPELESI United States Patent 3,528,123 CARPET FASTENING DEVICE James L. Dipelesi, Union Valley Road, Mahapac, N.Y. 10541 Filed July 1, 1968, Ser. No. 741,516 Int. Cl. A47g 27/04 US. CI. 16-16 6 Claims ABSTRACT OF THE DISCLOSURE A carpet fastening device, adapted to be secured to a surface, having an elongated thin strip of rigid material with inclined protruding projections, and a layer of resilient padding material on the top surface of the strip.

FIELD OF THE INVENTION The invention relates to securing fabric coverings, more specifically carpeting, the floors and other surfaces.

PRIOR ART The laying of carpets and other floor coverings is a relatively old art. Originally carpets were secured in place with nails or tacks. This technique was later improved on with the development of carpet securing strips. These strips in general have a relatively thin elongated base, typically of wood or plywood, which include upwardly extending projections. The projections, typically nails are all inclined in the same direction. In use the strips are secured to the floor along the edge of the room, or periphery of the area that the carpet is to cover. The carpet is then stretched and hooked on the projections. Variations of the securing strip were developed for ending the carpet, as for example across a doorway. Generally the strip included an upwardly extended flange along the leading edge. This flange could be bent over against the carpet after it was hooked in place.

When laying a carpet it is conventional to provide a relatively thick pad or cushion beneath the carpet. The pad is installed to abut the securing strip. The thickness of the pad usually is comparable to the thickness of the strip. Thus there is presented a generally smooth and flat upper carpet surface.

However, with this known arrangement the carpet over the securing strips wears at a faster rate than the carpet supported by the pad. This is particularly noticeable when the carpet ends over a well traveled area, such as a doorway. The carpet immediately above the strip rapidly becomes threadbare while the remaining carpet retains its original condition. The presence of the hooks may also accelerate the wear which together with the hard unpadded surface results in rapid wear. This situation frequently necessitates the replacement of large expanses of perfectly good carpet merely because a very small area is worn out.

There is thus presented a troublesome problem which prior to my invention did not have a satisfactory solution.

It is the object of this invention to reduce the rate of carpet wear which occurs over carpet securing strips.

Another object of the invention is to provide a carpet securing strip which reduces carpet wear and is convenient to install and relatively inexpensive.

SUMMARY OF THE INVENTION These and other objects are met by the carpet securing strip of my invention.

The carpet securing strip of the invention has an elongated base of rigid material, a plurality of spaced sharp projections extending outwardly from the top surface of this base, and a resilient layer of material on the top surface between the projections. The resilient layer of mate- 3,528,123 Patented Sept. 15,, 1970 rial provides a cushion over the hard upwardly facing surface of the base which reduces carpet wear over this region.

BRIEF DESCRIPTION OF THE DRAWINGS GENERAL DESCRIPTION Referring now to FIG. 1 and FIG. 2 of the drawing, there is shown a first preferred specific embodiment of the carpet fastening device of my invention. The carpet fastening device 10 has an elongated base 12 of rigid material. In the embodiment 10 the base is made of wood, preferably a strip of plywood approximately one-fourth of an inch in thickness and about three-fourths to one inch in width. It is understood, however, that the base can be made of any suitable material and have any suitable thickness and width. A plurality of spaced sharp projections 14 extend upwardly from base 12 approximately onefourth of an inch. The projections, as most clearly indicated in FIG. 2 are transversely inclined in a common direction. The projections 14 are typically nails driven through base 12. However, it is understood that the projections can be formed by any suitable elements or techniques.

A layer of resilient material 16 is provided on the top surface of base 12. The layer 16 can be any suitable thickness but is typically on the order of to of an inch. The layer can be made of any suitable resilient material such as rubber, jute, loosely woven fabric, hair, plastic material, foamed materials, or combinations thereof. The preferred material is a relatively thin layer of foamed or cellular plastic. The layer 16 is preferably adhered to base 12 by any suitable adhesive.

The carpet strip 10 is installed in the same manner as a conventional carpet securing strip, namely by securing it to the floor and hooking the carpet thereto. The additional layer of padding 16 makes a very significant difference in the wear characteristics of the finished carpet.

In FIG. 3 there is depicted still another preferred specific embodiment of my carpet fastening device 20. This type device is useful for usethrough doorways, or stopping the carpet in an open area. Device 20 has a base 22 of metal, typically an elongated strip of aluminum. Projections 24, used to engage the carpet 26, are formed from base 22 by cutting serrations from the strip and bending them upwardly as shown. An upwardly extending flange 28 is provided on the leading edge of base 22. In use carpet 26 is hooked into place in abutting relation to the flange 28, and the flange bent downwardly against the edge of the carpet. A resilient layer of material 30 is secured to the top surface of base 22 to provide a padding for carpet 26. The layer is similar to layer 16 as described in the embodiment described in FIG. 1 and FIG. 2.

The carpet fastening strip 20 is secured to the floor with nails 32, or other suitable means. If desired the strip can be formed into a channel configuration as shown in FIG. 3. In installing the carpet, the strip is typically secured, padding 32 is laid in abutting relation to strip 20, the carpet 26 hooked in place and flange 28 bent to securely hold the edge of the carpet.

While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and detail can be made therein without departing from the spirit and scope of the invention.

I claim:

1. In a carpet fastening device having an elongated base of rigid material having a top substantially flat surface, and a plurality of spaced sharp projections extending outwardly from the flat surface of the base and in clined in common transverse direction, the improvement comprising, a resilient layer of material adhered to said base on said relatively flat surface to serve as a carpet pad whereby wear on a carpet over said device is reduced.

2. The carpet fastening device of claim 1 wherein said material of said layer is a layer of cellular material.

3. The carpet fastening device of claim 1 wherein said elongated base is a metallic strip, and said projections are upwardly extending serrations of said strip.

4. The carpet fastening device of claim 3 wherein said metallic strip is provided with a generally upwardly extending flange.

5. The carpet fastening device of claim 1 wherein said elongated base is a woo-d strip, and said projections are nails protruding through said strip.

6. The carpet fastening device of claim 1 wherein said material of said layer is fabric material.
