Self-aligning ratcheting clasp
View Patent ↗A clasp comprising a securing rail and a clasp body. The securing rail comprises an elongate rail comprising a rail top, a pair of opposing clasping flanges extending lengthwise of the rail and a plurality of locking teeth spaced and extending lengthwise of the rail. The clasp body is configured to receive the clasping flanges of the elongate rail and to secure the clasp body to the rail against radial movement relative to the rail. At least one engaging tooth is operatively associated with the clasp body to engage the first plurality of locking teeth to secure the clasp body against movement in at least one axial direction lengthwise of the elongate rail with the clasping flanges received in the clasp body.
1. A clasp comprising:
a securing rail, the securing rail comprising an elongate rail comprising a rail top, a pair of opposing clasping flanges extending lengthwise of the rail, a first plurality of locking teeth spaced and extending lengthwise of the rail and an alignment trough in the top extending lengthwise of the rail; and
a clasp body comprising, a pair of opposing jaws operatively associated with the clasp body, each of the opposing jaws being configured to receive one of the clasping flanges of the elongate rail, the opposing jaws being further configured to bias toward each other with the clasping flanges received therein to nest the clasping flanges between the opposing jaws and to secure the clasp body to the rail against radial movement relative to the rail and an alignment blade extending from the clasp body, the alignment blade being configured to be received in the alignment trough with the opposing jaws receiving the clasping flanges, at least one engaging tooth on a distal end of a resilient flap extending from clasp body biased by the resilient flap into engagement with the first plurality of locking teeth to secure the clasp body against movement in at least one axial direction lengthwise of the elongate rail with the clasping flanges received in the clasp body and a pair of opposing levers, each lever being operatively associated with a jaw and the clasp body, the levers being configured so upon being squeezed together a first distance the jaws release the clasping flanges so that the clasp body can be moved radially relative to the clasping flanges.
2. The clasp of claim 1 further comprising the clasp body being integrally molded from a resilient plastic.
3. The clasp of claim 2 further comprising the resilient plastic causing the jaws to bias toward each other.
4. The clasp of claim 1 wherein the at least one engaging tooth and the plurality of locking teeth are configured for ratchet engagement, whereby the clasp body can slide one axial direction but not an opposite axial direction relative to the elongate rail with clasping flanges nested between the opposing jaws.
5. The clasp of claim 1 wherein the alignment blade extends lengthwise of the clasp body and is configured to be received lengthwise of the alignment trough.
6. The clasp of claim 5 wherein the alignment blade comprises first and second alignment blade segments with a gap therebetween.
7. The clasp of claim 6 wherein the engaging tooth resides in the gap between the first and second alignment blade segments.
8. The clasp of claim 1 wherein the resilient flap extends lengthwise of the of the clasp body in alignment with the alignment blade.
9. A clasp comprising:
a securing rail, the securing rail comprising an elongate rail comprising a rail top, a pair of opposing clasping flanges extending lengthwise of the rail, a first plurality of locking teeth spaced and extending lengthwise of the rail and an alignment trough in the top extending lengthwise of the rail; and
a clasp body comprising, a pair of opposing jaws operatively associated with the clasp body, each of the opposing jaws being configured to receive one of the clasping flanges of the elongate rail, the opposing jaws being further configured to bias toward each other with the clasping flanges received therein to nest the clasping flanges between the opposing jaws and to secure the clasp body to the rail against radial movement relative to the rail and an elongate alignment blade extending lengthwise along and from the clasp body, the alignment blade being configured to be received lengthwise in the alignment trough with the opposing jaws receiving the clasping flanges, at least one engaging tooth operatively associated with the clasp body biased into engagement with the first plurality of locking teeth to secure the clasp body against movement in at least one axial direction lengthwise of the elongate rail with the clasping flanges received in the clasp body and a pair of opposing levers, each lever being operatively associated with a jaw and the clasp body, the levers being configured so upon being squeezed together a first distance the jaws release the clasping flanges so that the clasp body can be moved radially relative to the clasping flanges.
10. The clasp of claim 9 wherein the alignment blade comprises first and second alignment blade segments with a gap therebetween.
11. The clasp of claim 10 wherein the engaging tooth resides in the gap between the first and second alignment blade segments.
12. The clasp of claim 9 wherein the engaging tooth extends from a distal end of a resilient flap extending from the clasp body, the engaging tooth being biased by the resilient flap into engagement with the first plurality of locking teeth.
