Abstract

A buckle has a main body, a strap retaining bar connected to the main body, two locking legs formed as separate pieces from the main body and pivotably connected to the main body; and a spring formed of two L-shaped sections disposed between the two locking legs. The spring is attached to both of the locking legs, and exerts a force against the locking legs when they are pressed inward toward each other. The spring keeps the locking legs in an outwardly tensioned position, but does not let the legs flex outwardly in an unlimited manner, since the spring is directly connected to the legs. The spring allows the main body and locking legs to be formed of an inflexible material, such as metal. The locking legs are separate pieces from the main body and are connected to the main body via a pivot pin or other hinged mechanism.

Abstract

A snap button has a female portion formed from a cap and a socket that are connected together with a piece of fabric in between. The cap is formed from a base body having a circumferential flange with interruptions therein so that the flange can be bent outward during assembly. The socket is formed by a disc having a central aperture and a peripheral rim, as well as an annular insert disposed within the socket. The cap is connected to the socket by pressing the socket onto the cap until the flange bends around the annular insert to anchor the cap to the socket with the fabric trapped between. A male portion having a stud is connected to the female portion by snapping the stud into the socket such that the stud extends entirely through the socket and into the cap.

Abstract

A buckle structure has a female part and a male part. The female part has a cavity for insertion of an axial tab formation of the male part, which has transverse seats on opposite lateral edges for engagement by fastening members on the female part. The fastening members have teeth located on opposite sides of a longitudinal direction of coupling of the buckle, which form between them a transverse aperture for the insertion of the tab formation. The buckle has button-like release members connected to the fastening members and operable manually by pressing transverse to the buckle, to disengage the fastening members from the seats. The fastening members and the release members act in coinciding or parallel transverse directions, so that the simultaneous pressing of the buttons towards each other causes the fastening teeth to move away from the engagement seats on the tab formation.
