Definitions

  • the present invention relates to a safety clasp, that is to say a clasp in two elements able to be assembled to each other and disassembled from each other at will, and each of which is intended to be attached to a part of an organ with a view to assembling it to another part of this organ or another organ.
  • This type of clasp is commonly used for bracelets and in particular watch straps.
  • a male element and a female element in which at least one central extension projecting from the front face of the male element can be engaged in a recess of complementary shape of the female element. and, in these known clasps, the retention of the extension of the male element in the recess of the female element is ensured by the engagement of at least one movable lug pushed by a spring means and carried by the extension of the male element, in cavities or windows provided to receive it in the recess of the female element.
  • connection thus obtained between the two elements of this clasp is an elastic connection that an effort exerted in the direction of their separation is often able to overcome easily, even when each lug is movable transversely to the direction in which the extension of the element male must be moved to be engaged in or released from the recess of the female element.
  • the extension of the male element is produced by folding a metal strip, one of the folds of which carries a movable lug resulting from a deformation or a puncture of this fold.
  • This lug like its stop notch formed in the recess of the female element, is subject to rapid wear as a result of friction which occurs in particular during the elastic engagement of the extension of the male element. in the recess of the female element, and which makes them lose their effectiveness.
  • the central extension of the male element carries at least two pistons each of which is pushed, by spring means, into a position in which it projects on the lateral face of the extension, while the recess of the female element has, housed in its two opposite lateral walls, two housings of which each is capable of containing the projecting part of one of the aforementioned pistons when the extension of the male element is engaged in the recess of the female element, a pusher accessible from outside the female element being associated to each of the housings of this female element to drive back and erase each piston in the extension of the male element and allow the extraction of this extension from the female element.
  • each projecting part of each piston is constituted by a cylinder segment terminated by a hemispherical end and each housing intended to receive it in the recess of the female element is a cylinder with a diameter slightly greater than that of the piston and of appropriate length.
  • connection obtained by the reciprocal engagement piston / cylinder is completely positive and can only be made free by the operation of the pushers and its behavior is absolutely not dependent on the degree of wear of the hemispherical ends of the pistons.
  • the extension of the male element carries, at its free end, a piston ejector normally kept projecting by spring means and driven back in the retracted position, when the element is extended male in the recess of the female element, by the bottom wall of this recess.
  • the bottom wall of the recess of the female element carries a spring means tending to oppose the engagement of the extension of the male element, so that this commitment has the effect of bandaging it.
  • This spring means therefore plays the role of ejector during the disassembly of the two elements of this clasp.
  • each housing formed in the recess of the female element to receive a locking piston of the male element is constituted by the bore of a ring of hard material, such as chrome steel or the like, reported in the aforementioned recess.
  • each element can be attached to the end of a flexible link such as a watch strap or the like and, in this case, it has means of a known type of attachment to this link, such as, for example, a housing of flattened rectangular section capable of accommodating the considered end of the link and one of whose large walls carries at least one locking screw.
  • each element of the clasp can be arranged in the body of the member to be assembled, such as a watch case.
  • this clasp is composed of two elements intended to be assembled together, namely a male element (2) and a female element (3).
  • the male element (2) comprises a body (2a) having, on its front face, a central extension (2b), while the female element (3) comprises a body (3a) whose front part (3b) forms a housing having a recess (3c) open on its front face and intended to receive and accommodate the central extension (2b) of the male element (2).
  • the central extension (2b), of flattened rectangular section has two rounded end edges (2'b), and, on the other hand, the recess (3c) of the housing (3b) of the 'female element (3) has a cross section corresponding to that of the extension (2b) of the male element (2).
  • each body (2a or 3a) of each of these two elements (2) and (3) has a housing, respectively (2'a) and (3'a), open towards the rear and intended to accommodate the corresponding end of the flexible link (4), clamping screws (5) carried by one of the large walls of the housing (2'a, 3'a) considered allowing the end of the link (4) to be blocked in this housing.
  • the extension (2b) of the male element (2) carries, on each of its opposite lateral faces, a piston (6) movable transversely to the longitudinal axis (4a) of the bracelet (4).
  • This piston (6) is mounted in a cylinder (7) fixed in the extension (2b), so as to be completely obliterated relative to the lateral face of this extension.
  • a spring (8) compressed between the piston (6) and the bottom of the cylinder (7) tends to hold a part of the piston (6) projecting relative to the corresponding side face of the extension (2b).
  • each piston (6) is composed of a cylindrical segment (6a) terminated by a hemispherical end (6b).
  • Each of the side walls of the recess (3c) of the housing (3b) of the female element (3) has, in correspondence with the location ment of the pistons (6) after engagement of the extension (2b) of the male element in this recess (3c), a housing (9) of complementary shape to the projecting part of the piston (6) considered and capable of housing this piston after assembly of the two elements (2) and (3), as illustrated in FIG. 3.
  • Each piston (6) therefore locks the assembly of the two elements (2) and (3) by its engagement in the housing ( 9) corresponding.
  • each housing (9) is associated with a pusher (11 ) coaxial with the housing (9) considered and whose rod (11a) is axially movable in the housing (9), against the action of a spring, not shown in the drawing.
  • one of the locking pistons (6) is shown in the locking position, with its pusher (11) at rest, while the other piston (6) is shown in the unlocked position, with its pusher (11) depressed.
  • the side wall of the recess (3c) has, near its opening, a track (12) in the form of a ramp which cooperates with the hemispherical end of the corresponding piston (6) to cause, as illustrated in FIG. 2, its erasure when the extension (2b) is introduced into the recess (3c ).
  • each housing (9) of the female element (3) is constituted by the bore of a ring (9a) made of hard material such as steel chrome or similar, and attached to the housing (3b) of the female element (3) to somehow constitute the side walls of the recess (3c).
  • the central extension (2b) of the male element (2) carries, at its free end, an ejector piston ( 13), in the same shape as the locking pistons (6), mounted in a cylinder (14) housed in the end of the extension (2b), so as to be completely obliterated with respect to this end, a spring (15) compressed between the piston (13) and the bottom of the cylinder (14) normally holding the piston (13) projecting from the free end of the extension (2b).
  • This clasp therefore has all the required safety conditions since in no case can it be inadvertently opened and therefore does not require the adaptation of any auxiliary safety chain.
  • each element (2) and (3) of this clasp has been described as being fixable at the free end of a bracelet (4).
  • each of these two elements could just as easily be arranged in a member to be assembled, such as, for example, in the case of a watch to which the strap would be attached directly.
  • the means for ejecting the extension (2b) of the male element (2) from the recess (3c) of the female element (3) has been described as being a piston (13) carried by the free end of the extension (2b).
  • means such as a leaf spring fixed to the bottom wall of the recess (3c), so that it is at least partially compressed at the end of engagement of the extension ( 2b) in the recess (3c).
