Abstract
A releasable clasp for a necklace or the like wherein a rigid housing having an open end houses a tubular holder of flexible material with a transverse web having a hole therethrough adjacent the open housing end. Also included is a shaft of rigid material having an enlarged head at one end thereof which is sized so that the shaft head can pass through the hole in the web with the application of a predetermined joining force and can be withdrawn therefrom only upon application of a pre-established withdrawal force. The housing and holder together form a first clasp part, while the shaft constitutes a second clasp part. The shaft may be twisted to detent into a locking position.
Claims14
A releasable clasp for a necklace or the like comprising a rigid housing having an open end, a holder supported by said housing therewithin, said holder comprising a web of flexible material having a hole therethrough adjacent said open housing end, said web being transverse to and joined to a wall structure of flexible material, the wall thickness of said wall structure being greater on that side of said transverse web closer to said open housing end than on the other side of said web, said housing and holder constituting a first clasp part, and a shaft of rigid material having an enlarged head at one end thereof, said shaft constituting a second clasp part, said enlarged head being sized so that it stretches said hole and passes therethrough with the application of a predetermined joining force and is withdrawn therefrom only upon application of a preestablished withdrawal force, so as to releasably join together said two clasp parts.
A releasable clasp for a necklace or the like comprising a rigid housing having an open end, a holder supported by said housing therewithin, said holder comprising a web of flexible material having a hole therethrough adjacent said open housing end, said housing and holder constituting a first clasp part, and a shaft of rigid material having an enlarged head at one end thereof, said shaft constituting a second clasp part, said enlarged head being sized so that it stretches said hole and passes therethrough with the application of a predetermined joining force and is withdrawn therefrom only upon application of a preestablished withdrawal force, so as to releasably join together said two clasp parts, in which said shaft includes a locking pin transverse thereto, and said rigid housing at said open end thereof includes a slotted flange through which said pin can pass, said flange retaining said locking pin thereunder when said shaft is twisted.
