United States Patent This invention relates to an anchoring device forv the marginal edge portions of a carpet or the like oor'covering for firmly securing and anchoringithe carpetin po sition. p

Heretofore, it has been a problem rin anchoring car pets t`o the floor to provide adequate securing means-for Normally the anchoring devices `have been made-of soft bendable metals and the securing-tangs'have the carpet.

been Ianced out from the vmetal so as to bite into the However, being of soft or bendablev material, pullson the carpet have caused the tangs to bendA back ror to break olf and release the carpet. n

The present invention overcomes these difculties V,by providing an anchoring means which willi securely hold the carpet in position and which comprises a simplified 'and inexpensive binding and/or anchoring means which can be easilyr andV quickly fabricated and installed.

This is accomplished by providing the anchoringmember', which-may be made of aluminum, brass, plastic' o r other bendable material, with a thickened `rib extending therea'long and by inserting through "the rib so asto project above the base, spikes of material? stronger tlian'the base material which will pierce the back of the carpet andi effectively hold vthe carpet against release from! the anchoring means. Preferably, the ribs extend downwardly from the base, which is adapted' to be secured to the oor, `andY are provided with .means'whereby the .nails can befreadily driven therethroughfso as to pierce the rib andprojectabove the base.

The present invention is aspecies of Ithe'invention shown and claimed inY my copending application Serial No. 491,375 and now Patent No. 2,820,980, issuedlan. .28, 1958. Y

Inone form of the invention the base is provided-with a rearwardly and upwardly extending cover .piece'fatits forward end which is adapted tobe bent down oventhe carpet to provide a protective binding or 4cover therefor.

In another formof the invention the Vbase is provided with a pair of dependingribs Vwiththe free-"fforwa-rdedge portionv of the base being adapted to receive -the-tucked -in carpetedge toV hold it in position; v

Ak feature of the invention residesin the fact 'that-.the

attaching strip can be made by Vusing anfeXtruded-section 'and by merely driving the nails therethrough-from the The extruded strip can be of relativelysoft the yrequired underside. lmaterial `and can be readily `severedvinto lengths.

Another feature of. the inventionresides-innovel means y ICC Fig. 4 is a view similar to Fig. 1 showing another form of the invention.

Fig. 5 shows the anchor strip of Fig. l secured lto a cement' iloor.

Fig. 6 is a top plan View of the fastening plate used in Fig. 5 to secure the attaching device to the door. Fig. 7 is a section taken along lines 7-7 of Fig. 6.

As shown in the drawings, one form of the anchor means of the present invention comprises an extruded section' 10 of aluminum, brass, plastic or other bendable material and provides a base member 11 having a thickened rib portion 12 and having at its forward edge a downwardly extending nosepiece 13 adapted to be pressed tightly against the floor when the anchoring member is secured thereto by nails 14 or other suitable means passing through elongate slots 11a in the base as shown in Figs. l and 2. The anchor member is adapted to be inserted under the edge of the carpet 15 with the base supporting the edge of the carpet. When the anchoring member is to serve as a binding means, it is provided at its forward edge with an upwardly and rearwardly extending protective member 16 adapted to be bent down 'and' cover the edge las shown in Fig. l. In order to hold the carpet in position, the present invention .provides a plurality of steel spikes 17 which are much stronger than the material of the base and which are driven through the rib. at spaced intervals soas to extend above the base and incline toward the edge of the carpet so as to pierce the back of the carpet as shown in Fig. 1. If the carpet is to be used with the usual padding, the ribs are formed to project downwardly and are of a height substantially equalto the padding 18 as shown in Fig. l.

While the spikes may be driven into the rib in any suitable manner, in the preferred form of the invention the rib is grooved at 1'9 so as to produce a transverse portion 20 of vthin crossesection throug'hwhich the spikes or nails can be driven. In the illustrated form of the invention a pair of grooves Z1, 22 are employed resulting kin a rib of H-shape cross-section, with the cross web of the H constituting the transverse portion 20. The walls of the grooves are spaced apart a distancev slightly less than the diameter of the nail so that as the nail is driven through the rib, it will not only pierce the transverse portion but it will be frictionally gripped by the walls of the grooves.

Under some circumstances it may be desired to secure the anchoring device to a concrete or the like oor 23 by means of cement 24 as shown in Figs. 5 through 7. In this case a perforated plate 25 is provided with an upwardly extending `tongue 26 which is adapted to be passed vthrough the elongate aperture 11a and bent over as shown in Fig. 5. In installing this type of mounting means, it is preferred to place the cement on the oor, insert the tongues of the plate into the slot, position the strip on the floor and locate the plates by the position of the strip. The strip is then removed and the cement is permitted to harden. After' the cement is hardened, the anchoring strip is positioned over the tongues and the upwardly extending tongues arefolded over as shown in Fig. 5 lto securely fasten the anchoring means in place. Further, -it will be noted that `the downwardly extending nosepiece not vonly seals'the edge of the anchoring means at the floor but also provides clearance under tbase to accommodate the plate 25 when the anchoring means is secured thereby. f

In the form of the invention shown in Fig. 4 which is preferable for use along walls where protection of the edge of the carpet is not necessary, the base 31 is provided with a plurality of thickened ribs. While the number of ribs `may vary, in the illustrated form of the invention, I employ a pair of depending ribs 32, 33 similar to rib 12'.

In the preferred form of the invention the ribs are arranged with one adjacent the rear edge and the other spaced inwardly from the front edge of the base so as to provide a projecting free edge portionvlb spaced above the ioor and under which the edge of the carpet may be tucked.

Each of the ribs is provided with a plurality of spaced spikes or nails 34, as shown in Fig. 4, which extend through the ribs and above the base so as to securely bite into or pierce the back of the carpet l5 and hold it in position. The anchoring member of Fig. 4 is provided with apertures 31a in the base similar to those described in connection with Fig. l and can be secured by nails ll4 or by the cementing clips -of Fig. 6 as required.

From the foregoing it will be seen that l have provided a novel anchor strip which can be readily made and assembled and which includes an extruded section of readily bendable material, such as aluminum, brass, plastic or rubber, which can be severed into the desired lengths. The strip is provided with nails or the like which are mounted in ribs in the strip and are stronger than the strip to provide an adequate anchor for the carpet. The anchor strip of the present invention can be readily mounted by being fastened with nails or the like or can be cemented down and anchored in the novel combination disclosed herein. Also, the present invention can be formed as binding strips with protective portions extending over the edge of the strips as are used for exposed edges of carpet, or can be used to anchor the edge of the carpet adjacent the wall.

Variations and modications may be made lwithin the scope of the claims and portions of the improvements may be used without others.
