Abstract
Abstract A collet for a tufting button comprises a one piece molded plastic body having a peripheral side formed with a series of annular steps. When a button shell is crimped onto the collet with button-covering material interposed between the sidewall of the shell and the side of the collet, the steps form slipresistant regions that are engaged by the covering material to prevent separation of the shell and cover material from the collet. The base of the collet has a stem with a hook structure for receiving a pre-tied tufting loop. Dual snap locks are provided to prevent removal of the tufting loop.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
222 words
In a button collet for a tufting button comprising a body with a central axis, said body having a base, a peripheral side surrounding said axis and joined to said base, and means projecting from said base and including a stem having a recess for receiving a length of a tufting loop; an improvement in said means that comprises first resilient means forming a first snap lock for retaining the tufting loop on the stem, said first resilient means including a hook cooperating with an adjacent shank that forms part of said projecting means, and second resilient means forming a second snap lock for retaining the tufting loop assembled with the collet if the loop is accidentally withdrawn from said recess and past the first snap lock and for providing an obstruction against the entry of an additional length of the tufting loop into said recess, the second and first snap locks thereby being in mechanical series so that the tufting loop must be snapped past both locks in sequence to position the tufting loop in said recess, and the snap locks furthermore being relatively positioned such that the tufting loop can be snapped past the two snap locks without reversal of direction of movement of said tufting loop, said first snap lock being axially between said second snap lock and recess.

Dependent Claim

Claim 3
Dependent Claim
29 words
A button collet according to claim 1 in which said peripheral side has a series of annular steps of progressively increasing diameter in the direction away from said stem.
Claim 4
Dependent Claim
192 words
A button collet for a tufting button comprising a body having a central axis and a base, a stem projecting from said base, a resilient hook joined to the end of said stem that is remote from said base and cooperating therewith to fOrm a recess, said hook having an arcuate bend and a termination spaced from said stem and at the free end of said arcuate bend to provide a first gap through which a tufting loop is adapted to snap upon deflection of the hook away from said stem a sufficient amount to permit passage of such tufting loop into said recess, and a resilient tab joined to said base and having a termination spaced from said arcuate bend and remote from said hook termination to provide with said arcuate bend a second gap through which the tufting loop snaps, upon sufficient deflection of said tab, prior to snapping through said first-mentioned gap, said gaps being positioned such that the tufting loop can be snapped through said gaps without reversal of direction of movement of said tufting loop, said first gap being axially between said second gap and said recess.
Claim 5
Dependent Claim
