Abstract

Abstract A detachable bandage clasp is disclosed which is removably fastened to a fold in or the end of a bandage by means of two opposed sets of teeth contained on a set of jaws connected by a torsion spring hinge means. The jaws are centrally positioned to clasp and hold when in their closed position a portion of the bandage. The jaws are opened to release the bandage by a torsional pressure exerted on two lateral wing plates positioned on either side thereof and molded integrally thereto. This torsion on the wing plates causes flexure of the plastic jaw hinge. The jaws are closed by a release of the torsion exerted thereon. On the distal end of each lateral wing plate there is at least one tine which engages an underlying layer of wrapped bandage when the clasp is in use. In a preferred embodiment the tine extends out from the lateral wing plate at a right angle to the plate and bends at a right angle also so that the tip of the tine is pointing toward the centrally located jaws and hinge and the shaft of the tine is parallel to the plane of the lateral wing plate.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 102 words
A fastener for bandages which comprises a plastic resilient frame consisting of a centrally positioned set of jaws having interposed therebetween a tortion actuated spring hinge and a set of lateral wing plates which control the opening and closing of the said jaws when pressures are applied or released thereon, a bandage securing means positioned distally on each lateral wing plate and adapted to engage an underlying layer of wrapped bandage, said jaws capable of clasping releasably a segment of the bandage in an opposed set of teeth located thereon and holding the same until released by a second application of torsion.
Claim 2
Dependent Claim 102 words
A fastener for bandages which comprises a plastic resilient frame consisting of a centrally positioned set of jaws having interposed therebetween a tortion actuated spring hinge and a set of lateral wing plates which control the opening and closing of the said jaws when pressures are applied or released thereon, a bandage securing means positioned distally on each lateral wing plate and adapted to engage an underlying layer of wrapped bandage, said jaws capable of clasping releasably a segment of the bandage in an opposed set of teeth located thereon and holding the same until released by a second application of torsion.
Claim 3
Dependent Claim 72 words
A fastener clasp according to claim 1 wherein the bandage securing means positioned on each lateral wing plate comprises a combination of a tine support bar extending out at right angles to the plane of the lateral wing plate, a shaft of said tine extending at right angle to the support bar and a tip on said tine shaft both pointing in the direction of the said central jaws and spring hinge.
Claim 4
Dependent Claim 53 words
A fastener clasp according to claim 1 wherein the bandage securing means comprises a tine support bar extending in the same plane as the lateral wing plate, a tine shaft also in said plane and a tine tip and shaft both pointing in the direction of the said central jaws and spring hinge.
Claim 5
Dependent Claim 38 words
A fastener clasp according to claim 1 wherein the bandage securing means comprises a tine which is deflectable out of the plane of the lateral wing plate by lateral pressure exerted thereon transmitted from its tine support bar.
Claim 6
Dependent Claim 61 words
A fastener clasp according to claim 1 wherein the bandage securing means comprises a tine support bar medially located between each of two tine shafts each of said shafts having a tine tip thereon pointing in the direction of the central jaws and hinge and each tine flexurally deflectable out of the plane of its original position by pressure exerted thereon.
Claim 7
Dependent Claim 58 words
A bandage assembly comprising a strip of bandage material in predetermined length folded into an accordion pleat in a container with an outer end of the bandage adapted to be pulled out of the container through a nearby opening therein, the inner end of the bandage strip attached to the jaws of a fastener clasp of claim 1.
