Problems solved by technology

However, it is difficult to make the tongues sufficiently deformable because they are relatively large and attach to the bottom of the plug part along a relatively long edge or surface of the plug part
Resistance to tongue flexing or bending making it difficult to release the buckle

Embodiment Construction

[0017] refer to figure 1 with figure 2 , the buckle of the present invention is generally indicated with reference numeral 1 . Buckle 1 is typically used to attach the free end of a strap (not shown). The buckle 1 comprises two parts, a female socket part 4 and a male plug part 5 . Buckle 1 and its components may preferably be molded from plastic or resin, but any suitable material known in the art for molding or machining buckles may be used.

[0018] In an embodiment, the socket member 4 may be integrally molded with a single strap bar 6 . The rod 6 is spaced from the socket body to form a space 7 to accommodate the strap (see figure 1 ). A strap (not shown) can be looped around the rod 6 and fastened to itself, thereby connecting the strap to the socket part 4 . The plug member 5 may be integrally molded with a pair of crossbars 2 and 3 near one end thereof which receive straps in known manner to make the straps adjustable, for example as described in US Pat. No. 5,2...

Abstract

A buckle having a socket member and a plug member which may be coupled to the socket member. Latching surfaces on the plug member are formed on in resiliently flexible legs which extend from the base of the plug member. The socket member includes stopping members for engaging the latching surfaces of the legs in order to couple the plug member to the socket member. A button formed on the socket member includes a releasing member which is pushed down into the socket and forced into a space between the legs, thereby forcing the flexible legs to bend outwardly. As the legs are forced outwardly, eventually their latching surfaces clear the stopping members, and the plug member is released form the socket. The resiliently flexible nature of the legs provides a force upon disengagement of the latching surfaces from the post, which causes the plug member to spring out of the socket.

Description

field of invention [0001] The present invention relates to a buckle for connecting two straps together, wherein the buckle is disengaged or opened by pressing a centrally located button or flap. In particular, the present invention relates to such a buckle with improved locking capability. Background technique [0002] A common buckle for securely attaching a strap so that the buckle can be released is described, for example, in US Pat. For plug parts. Each plug member and socket member has a crossbar to which straps can be attached. The socket member defines a passage therethrough adapted to receive a portion of the plug member when the buckle members are interconnected. Each plug member has a tongue forming a locking surface adapted to engage a stop in the receptacle. The tongues are resiliently deformable so that when they slide into the socket part their locking faces engage a stop in the socket to lock the buckle in the closed position. [0003] Conventional buckle...
