Claims
- 1. 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so that it stretches said hole and passes therethrough with the application of a predetermined joining force and is withdrawn therefrom only upon application of a preestablished withdrawal force, so as to releasably join together said two clasp parts.
- 2. A releasable clasp according to claim 1, in which said wall structure comprises a tubular member.
- 3. A releasable clasp according to claim 2, in which said web is intermediate the ends of said tubular member.
- 4. A releasable clasp according to claim 3, in which said second clasp part includes an enlargement thereon at a part of the shaft spaced from said enlarged head, said enlargement being seated against said web.
- 5. A releasable clasp according to claim 4, in which said enlargement has an outer surface that fits within and against the inner surface of said tubular member at the end thereof adjacent said open housing end.
- 6. A releasable clasp according to claim 5, in which said holder is of high tear strength and long flex life stretchable material.
- 7. A releasable clasp according to claim 1 in which said holder is supporeted within and by said rigid housing with a space between an inside wall portion of said housing and said wall structure of said holder.
- 8. A releasable clasp according to claim 7, in which said holder is contacted only at the ends of its wall structure by said rigid housing.
- 9. 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.
- 10. A releasable clasp according to claim 9, in which said locking pin is urged against the underside of said flange by the adjacent end of said tubular member.
- 11. A releasable clasp according to claim 10, in which said flange includes ridges on the underside thereof to retain said locking pin in shaft-locked position.
- 12. 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 holder is of high tear strength and long flex life stretchable material, said web is transverse to and joined to a wall structure of a material the same as said web, said web is intermediate the ends of said wall structure, the wall thickness of said wall structure is greater on one side of said web than on the other side of said web, said web is positioned closer to that end of said wall structure of greater wall thickness than to the other end, and said holder is of increasing wall thickness proceeding from the end thereof closer to said web toward said web.
- 13. A releasable clasp according to claim 12, in which said rigid housing is tubular, and said tubular wall structure of said holder is supported within and by said rigid housing with a space between an inside wall portion of said tubular housing and said tubular wall structure of said holder.
- 14. A releasable clasp according to claim 13, in which said holder is contacted only at the ends of its tubular wall structure by said rigid housing.
