Abstract
Abstract A buckle includes a male member (20) having a tongue-shaped presser (21) having on its lower side a pair of engaging legs (24, 24) and a female member (1) including in its upper side an aperture (2) for insertion of the engaging legs (24, 24), and a pair of transversely spaced resilient arms (4, 4) adapted for angular movement around their proximal ends (5, 5) against their own resiliency, the arms (4, 4) having on their middles engaging means (6, 6) for engagement with the engaging legs (24) when the engaging legs (24, 24) are forced through an aperture (2). An uncoupling means (10) are rotatably mounted on the upper side of the female member (1) and so operatively linked with the free ends (4′, 4′) of the resilient arms (4, 4) that the rotation of the uncoupling means (10) causes the resilient arms (4, 4) angularly move against their own resiliency, thereby bringing the engaging means (6, 6) out of engagement with the engaging legs (24, 24).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
220 words
A buckle comprising: a male member (20) having a tongue-shaped presser (12) having on its lower side a pair of engaging legs (24, 24); a female member (1) being in the form of a case and including in its upper side an aperture (2) for insertion of the engaging legs (24, 24), and a pair of transversely spaced resilient arms (4, 4) forming integrally to one end of the female member (1) and terminating in free ends (4′, 4′) for angular movement around their proximal ends (5, 5) against their own resiliency, the arms (4, 4) having engaging means (6, 6) for engagement with the engaging legs (24) when the engaging legs (24, 24) are forced through an aperture (2); and an uncoupling means (10) for bringing the engaging means (6, 6) out of engagement with the engaging legs (24, 24), the uncoupling means having a disk (11) rotatably mounted on the upper side of the female member (1); characterized in that the uncoupling means further includes linking means (16, 16; 17, 17) for so operatively linking the disk (11) and the resilient arm (4,4) that the rotation of the disk (11) causes the resilient arms (4, 4) angularly move against their own resiliency, thereby bringing the engaging means (6, 6) out of engagement with the engaging legs (24, 24).
Claim 2
Dependent Claim
220 words
A buckle comprising: a male member (20) having a tongue-shaped presser (12) having on its lower side a pair of engaging legs (24, 24); a female member (1) being in the form of a case and including in its upper side an aperture (2) for insertion of the engaging legs (24, 24), and a pair of transversely spaced resilient arms (4, 4) forming integrally to one end of the female member (1) and terminating in free ends (4′, 4′) for angular movement around their proximal ends (5, 5) against their own resiliency, the arms (4, 4) having engaging means (6, 6) for engagement with the engaging legs (24) when the engaging legs (24, 24) are forced through an aperture (2); and an uncoupling means (10) for bringing the engaging means (6, 6) out of engagement with the engaging legs (24, 24), the uncoupling means having a disk (11) rotatably mounted on the upper side of the female member (1); characterized in that the uncoupling means further includes linking means (16, 16; 17, 17) for so operatively linking the disk (11) and the resilient arm (4,4) that the rotation of the disk (11) causes the resilient arms (4, 4) angularly move against their own resiliency, thereby bringing the engaging means (6, 6) out of engagement with the engaging legs (24, 24).
