UNITED STATES PATENT OFFICE DETAGHABLE FASTENER Henry Pommier, New York, N. Y.
Application September 20, 1945, Serial No. 617,492
I 6 Claims. l
This invention relates to a detachable fastener, and more particularly to a novel clasp for bracelets, necklaces and the like.
It is among the objects of thisinvention to provide an easily engaged and disengaged clasp having an eicient and certain locking action; to provide such a clasp including a .pair of male and female members and having cooperating interlocking means, and means effective to engage such interlocking means; to provide a clasp including a female member having a displaceable Wall portion, a male member engageable in the female member, cooperating interlocking means on the wall portion of the male member, and means operable to displace the wall portion to engage the interlocking means; and to provide a novel, neat appearing, easily operated andeicient clasp.
These and other objects, advantages and novel features of the invention will be apparent .from
the following description and the accompanying drawing.
In the drawing:
Fig. 1 is a perspective view, partly broken away, of a bracelet provided with a clasp according to the present invention. n
Fig. 2 is a transverse sectional View on the 'line 2-2 of-Fig. 1, with the clasp in the o-pen position.
Fig. 3 is a perspective view showing the clasp in the partly engaged position.
Fig. 4 is a transverse sectional view taken along the line 2-2 of Fig. 1 with the male member of the clasp fully inserted in the female member 'of the clasp.
Fig. 5 is a perspective View, partly in section, showing the clasp in the fully engaged position.
According to the present invention, a clasp is providedy including a female member preferably rectangular in cross-Section and having one wall formed with an outwardly sprung portion. A male member, likewise rectangular in cross-section, is insertable in the female member. Cooperating interlocking means are formed on the male member and the Wall portion to interlock the clasp elements. A member, preferably a channel, is pivotally mounted on the female member so that it may be displaced into embracing relation with the sprung wall portion of the female member to engage such interlocking means to interlock the members of the clasp.
Referring to the drawing, the clasp is illustrated as having a pair of members secured to either end of a bracelet I0, which is illustrated as of the so-called snake chain variety. The clasp comprises female member I5 and a male tially inserted in female member be engaged in aperture 22.
For a`purpose to be described, channel-shaped member is pivotally mounted on member I5 as by being pivoted to a pin 2B extending transversely of member I5 adjacent its attachment to. bracelet I0. Member 25 is provided with an upper wall or base 21 and a pair of parallel side walls, flanges, or .legs and 3|. Upper wall 2l is formed with an abutment or lip 32 which may be engaged by the nger to release the clasp. Male 'member 2D includes parallel opposite side walls 36, 3'I each formed with a pro-tuberance 4I, 42. The protuberances 4I, 42 are transversely aligned and so located that they will enter apertures 22 and 23, respectively, when the male member 20 is fully engaged in female member I5.
Fig. 3 illustrates the clasp in the partially engaged position in which male member Z is par- I5 and element 25 is disposed in the upper position. Wall portion 2| is sprung outwardly a considerable amount so that even when member 2D is fully; engaged in member I5, protuberance All will not When member 2li has been fully inserted in member I5, member 25 is swung downwardly about pivot pin 26 and embraces opposite side walls I'I and I9 to move wall portion 2l inwardly so that protuberance 4I is engaged in aperture 22. This is the locked position of the latch. Such action likewise forces lprotuberance 42 into aperture 23, as shown in Fig. 4.
To release the latch, the wearer grasps lip 32 g to swing channel 35 to its upper position shown 'corresponding protuberances may be formed on the inner surfaces of wall I1 and wall portion 2 I. In such event, wall portion 2| will likewise be sprung outwardly so as to permit easy disengagement of member 20 from member I5 when channel 25 has been moved to the upper position.
The described clasp comprises an eil'icient vfastener for bracelets, straps and the like. It is easily engaged and disengaged, and when completely engaged is securely locked until such time as channel 25 is moved to the upper position.
While a specic embodiment of the invention has been described and shown in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be otherwise embodied without departing from such principles.
What is claimed is:
1. A clasp comprising, in combination, a female member having a pair of opposite walls formed with interlocking means, one of said walls being outwardly sprung; a male member having a pair of opposite walls formed with interlocking elements and engageable in said female member; said sprung wall portion being laterally 'spaced from said male member in the engaged position of said members; and means movably mounted on one of said members for movement in a plane parallel to the inward position of said sprung wall portion and effectivein such movement, to frictionally engage said sprung wall portion to move the same inwardly to engage said male member and to displace said male member laterally to engage said interlocking means with said interlocking elements to lock said members together.-
2. A clasp comprising, in combination, a female member having a pair of opposite walls, one having an aperture therein and the other having an outwardly sprung portion formed with an aperture; a male member engageable in said female member and having a pair of oppositely projecting protuberances receivable in such apertures; said sprung wall portion being laterally spaced from said male member in the engaged position of said members; and means hingedly mounted on said female member for movement in a plane parallel to the inward position of said sprung wall portion and effective, in such movement, to frictionally engage said sprung wall portion to move the same inwardly to engage said male member and to displace said male member laterally to retain said protuberances in such apertures to interlock said members.

Aclarsp comprising, in combination, a female member having an outwardly sprung wall prtion; a male member engageable in said female member; cooperable interlocking means on said wall'portion and said male member; said sprung wall portion being laterally spaced from said male member in the engaged position of said members; and means hingedly mounted on said female member for movement in a plane parallel to the inward position of said wall portion and effective, in such movement, to frictionally engage said wall portion and move the same inwardly to engage said male member to interengage said interlocking means to interlock said members.
6. A clasp comprising, in combination, a female member having an outwardly sprung wall portion; a male member engageable in said female member; cooperable interlocking means on said wall portion and saidmale member; said sprung wall portion being laterally spaced from said male member in the engaged position of said members; and a channel element hingedly mounted on said female member for vmovement in a plane parallel to the inward position of said wall portion into embracing relation with said female member, a liange of said elementbeing effective, in such movement, tofrictionally engage said wall portion and move the same inwardly to engage said male member to interengage said interlocking means to interlock said members.
