US4198733A — Fabric covered button

Claim 1

Independent Claim 352 words

A fabric covered button comprising a button portion in the form of a button head having on the rear face thereof a cylindrical-shaped stem of a diameter smaller than said button head and attachment means for securing said fabric covered button head and attachment means for securing said fabric covered button to an article integrally formed with the terminal end of said stem; a piece of fabric draped over said button head and extended around its edge to the rear thereof; and a circular-shaped collet retainer secured about said stem having a concave-shaped top wall and an annular depending side wall, the edges of said fabric at the rear of said button head being secured between the rear of said button head and the peripheral edge of said top wall of said collet retainer, said side wall of said collet retainer extending away from said button head, whereby the terminal edges of said side wall are prevented from cutting said fabric, said top wall having a central hole which can receive said stem, the peripheral portion of said top wall adjacent said central hole being angularly bent downwardly at a relatively sharper angle than the remainder of said top wall to form a camming surface which is engageable by said stem, the diameter of said central hole being smaller than the diameter of said stem, said collet retainer being secured to said stem with said side wall extending away from said rear face of said button head by forcibly urging said stem through said central hole by engaging said camming surface such that said top wall flexes outwardly sufficiently to receive said stem through said central hole and to permit the edge of said central hole about its diameter to frictionally engage said stem as said collet retainer is forcibly urged upwardly on said stem, said collet retainer being securely locked to said stem when the force urging said collet retainer upwardly on said stem is released permitting said top wall to flex inwardly sufficiently to cause the edge of said central hole about its diameter to effectively bite into said stem.

Claim 2

Dependent Claim 352 words

A fabric covered button comprising a button portion in the form of a button head having on the rear face thereof a cylindrical-shaped stem of a diameter smaller than said button head and attachment means for securing said fabric covered button head and attachment means for securing said fabric covered button to an article integrally formed with the terminal end of said stem; a piece of fabric draped over said button head and extended around its edge to the rear thereof; and a circular-shaped collet retainer secured about said stem having a concave-shaped top wall and an annular depending side wall, the edges of said fabric at the rear of said button head being secured between the rear of said button head and the peripheral edge of said top wall of said collet retainer, said side wall of said collet retainer extending away from said button head, whereby the terminal edges of said side wall are prevented from cutting said fabric, said top wall having a central hole which can receive said stem, the peripheral portion of said top wall adjacent said central hole being angularly bent downwardly at a relatively sharper angle than the remainder of said top wall to form a camming surface which is engageable by said stem, the diameter of said central hole being smaller than the diameter of said stem, said collet retainer being secured to said stem with said side wall extending away from said rear face of said button head by forcibly urging said stem through said central hole by engaging said camming surface such that said top wall flexes outwardly sufficiently to receive said stem through said central hole and to permit the edge of said central hole about its diameter to frictionally engage said stem as said collet retainer is forcibly urged upwardly on said stem, said collet retainer being securely locked to said stem when the force urging said collet retainer upwardly on said stem is released permitting said top wall to flex inwardly sufficiently to cause the edge of said central hole about its diameter to effectively bite into said stem.

Claim 3

Dependent Claim 58 words

The fabric covered button of claim 1, said button head on the rear face thereof having an annular recessed cavity about said stem, the depth and diameter of said cavity being such that said collet retainer can be received within it, the edges of said fabric being disposed within said cavity and secured therein by said collet retainer.

Claim 4

Dependent Claim 34 words

The fabric covered button of claim 2, wherein the depth of said recessed cavity and the method in which its collet retainer is lockingly secured to said stem compensating for fabrics of different weights.

Claim 6

Dependent Claim 34 words

The fabric covered button of claim 1, wherein the terminal end of said stem about its periphery is formed with a tapered camming surface, for assisting in assembling said collet retainer on said stem.
