DETAILED DESCRIPTION OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1, a fastener in accordance with the present invention is shown comprised of a male fastening member and a female fastening member respectively molded from flexible material, for example, plastics.

The male fastening member comprises a base panel , a spacer block integral with the surface of the base panel , a cylinder integral with the top surface of the spacer block in parallel to the base panel , a spherical retaining head , and a neck connected between one end of the cylinder and the periphery of the spherical retaining head .

The female fastening member comprises a base panel , and a socket shell integral with the top surface of the base panel . The socket shell comprises a transversely extended receiving hole adapted for receiving the cylinder of the male fastening member , a top opening extended to the front open side thereof corresponding to the width of the spacer block , and a retaining rib integral with the rear open side thereof.

Referring to FIGS. from through , the spacer block and cylinder of the male fastening member are aimed at the transversely extended receiving hole of the socket shell of the female fastening member , and then the male fastening member is moved toward the female fastening member in the arrowhead direction A to force the cylinder and the spherical retaining head into the receiving hole of the socket shell . At this time, the spacer block is engaged into the top opening , and the spherical retaining head is forced out of the rear open side of the socket shell , keeping the neck in engagement with the retaining rib of the socket shell , and therefore the male fastening member and the female fastening member are fastened together. On the contrary, when unfastening the fastening members and , pull the male fastening member from the female fastening member in direction reversed to the arrowhead direction A.

As indicated above, when fastened up the male fastening member and the female fastening member , the retaining rib of the female fastening member and the neck of the male fastening member are engaged with each other, keeping the male fastening member and the female fastening member positively secured together.

Referring to FIG. 5, the male fastening member and the female fastening member are respectively mounted on a respective piece of sock or , for enabling the sockets and to be detachably fastened together.

A prototype of fastener has been constructed with the features of FIGS. ˜. The fastener functions smoothly to provide all of the features discussed earlier.

Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
