Fastener for attachment of a continuous article to a support

Claim 2

A multi-part fastener adapted to releasably attach carpet-like and panel-like members to a support, said multi-part fastener comprising a plurality of fastening elements including at least first and second fastener elements, said first fastener element includes an annular coupler having a top portion and a plurality of rigid projections extending from the outer edge of one side of said top portion, said top portion having means integrally associated with the outer edge thereof for limiting snagging-type of engagement of objects that contact therewith, said second fastener element having fastening means extending from one side thereof for attachment to a support and a generally annular and radially extending flange with a non-constant outer diameter, whereby rotation of said first and second fastener elements relative to the carpet-like member is inhibited and said fastener fastening means is engageable with said support to releasably attach said carpet-like member thereto, said rigid projections of said coupler adapted to penetrate the carpet-like member and the radially extending flange of said second fastener and be folded under said flange to lock the carpet-like member between said first and second elements.

Claim 3

The multi-part fastener according to claim 1, wherein said radially extending flange of the second fastener element includes an area of a predetermined thickness.

Claim 4

The multi-part fastener according to claim 2 wherein said radially extending flange has at least one area of a reduced thickness which is less than the predetermined thickness of said flange where the projections may readily penetrate therethrough.

Claim 5

The multi-part fastener according to claim 3 wherein the radially extending flange has areas of reducing thickness between the area of predetermined thickness and the area of reduced thickness to guide the projections into the area of reduced thickness.

Claim 6

The multi-part fastener according to claim 2 wherein the radially extending flange includes a plurality of elongated apertures therein corresponding to and registrable with the plurality of rigid projections.

Claim 7

The multi-part fastener according to claim 5, wherein the area around each of said elongated apertures in the radially extending flange is inclined to guide each corresponding one of the rigid projections into one of the apertures.

Claim 8

The multi-part fastener according to claim 2 wherein said radially extending flange has its outer peripheral edge portion deflected away from the direction in which the fastening means extends, whereby the deflected portion of the flange causes a mounding of the carpet-like member around the top portion of the annular coupler.

Claim 9

The multi-part fastener according to claim 1, wherein said fastening means extending from said second fastener element includes a female portion of a two-part male/female fastening assembly and a separable male portion having means associated therewith for direct attachment to said support, whereby the carpet-like member may be releasably attached to the support by the engagement of the male and female portions of said two-part male/female fastening assembly.

Claim 10

The multi-part fastener according to claim 1, wherein the means integrally associated with the outer edge of the top portion of the coupler is a flange extending substantially perpendicularly from said one side of said top member.

Claim 11

The multi-part fastener according to claim 9, wherein the outer peripheral edge of the other side of said top member is radiused.

Claim 12

The multi-part fastener according to claim 9 wherein said plurality of rigid projections extend integrally from the free edge of said flange on said one side of the coupler, said projections being pointed at their free ends to assist in the penetration of said carpet-like mumber and said radially extending flange.

Claim 13

A multi-part fastener adapted to releasably attach carpet-like and panel-like members to a support, said multi-part fastener comprising a plurality of fastening elements including at least first and second fastener elements, said first fastener element includes an annular coupler having a top portion and a plurality of rigid projections extending from the outer edge of one side of said top portion, said top portion having means integrally associated with the outer edge thereof for limiting snagging-type of engagement of objects that contact therewith, said second fastener element having fastening means extending from one side thereof for attachment to a support and a radially extending flange, said rigid projections of said coupler adapted to penetrate the carpet-like member and the radially extending flange of said second fastener and be folded under said flange to lock the carpet-like member between said first and second fastener elements, said radially extending flange of the second fastener element includes an area of a predetermined thickness, the radially extending flange includes a plurality of elongated apertures therein corresponding to and registrable with the plurality of rigid projections, the area around each said elongated aperture in the radially extending flange is inclined to guide each corresponding one of said rigid projections into one of the apertures, and said second fastener element is generally annular with a non-constant outer diameter, whereby rotation of said first and second fastener elements relative to the carpet-like member is inhibited.

Claim 14

A multi-part fastener adapted to releasably attach carpet-like and panel-like members to a support, said multi-part fastener comprising a plurality of fastening elements including at least first and second fastener elements, said first fastener element includes an annular coupler having a top portion and a plurality of rigid projections extending from the outer edge of one side of said top portion, said top portion having means integrally associated with the outer edge thereof for limiting snagging-type of engagement of objects that contact therewith, said second fastener element having fastening means extending from one side thereof for attachment to a support and a radially extending flange, said rigid projections of said coupler adapted to penetrate the carpet-like member and the radially extending flange of said second fastener and be folded under said flange to lock the carpet-like member between said first and second fastener elements, said radially extending flange of the second fastener element includes an area of a predetermined thickness, the radially extending flange includes a plurality of elongated apertures therein corresponding to and registrable with the plurality of rigid projections, the area around each said elongated aperture in the radially extending flange is inclined to guide each corresponding one of said rigid projections into one of the apertures, and said second fastener element is generally annular with a non-constant outer diameter, whereby rotation of said first and second fastener elements relative to the carpet-like member is inhibited.
