Description

Fasteners for jewelry or watches

The present invention relates to a fastener for a piece of jewelry or a wristwatch, comprising a stretcher-like structure having a first housing, a first pusher and a second pusher in the outer casing The anti-elastic return mechanism moves on a first bearing surface and is held by at least one cover plate, and the first and second pushing members can occupy a cover position of a second outer casing.

The invention also relates to a bracelet comprising at least one such fastener.

The invention also relates to a wristwatch comprising such a bracelet.

The present invention relates to the field of watchmaking and jewellery, and more to the field of watches and bracelets.

Many fastener variations are used in watchmaking and jewelry to open or close the bracelet, especially the strap. These fasteners allow the bracelet's strands to contact each other and remain in a combined position, which creates an actual tight bundle. The bracelet hinges are typically hinged at the ends of the lockable folding arms, which are then hinged to the ends of the stretcher-like structure, the stretcher-like structure A locking mechanism complementary to the locking mechanism of the folding arms. The folding arms can be unlocked with force or preferably with a pusher element. The fasteners generally have a pusher that is movable in the opposite direction relative to the stretcher member against compression of a return element for locking or unlocking the fold arm when the fastener is closed or opened.

French Patent No. 2,825,244 discloses a folding wristband fastener having a pusher member comprising a substantially H-shaped stretcher-like structure, the stretcher structure having a mounting structure for opposing two pushers and a A return element configuration in the form of a moving strip spring of the pusher. A support plate holds the pushers, the belt spring and the hooking system abut against the stretcher-like structure to open and close the fastener. The support plate (which is also H-shaped) has two symmetrical holes defined by parallel branches for the mounting arms, opposite the hinge portion and having an articulated assembly for a portion of the wristband structure. The stretcher-like structure and the H-shape of the support plate create machining complexity because it is more expensive with four outer casings for precision screws. These holes must be centered with higher precision and aligned on the parallel arms of H, and the structure in which the band spring is placed in the cross arm of the H is extremely complicated; this is for the two pushers. Installation and operation and assembly of two parallel branches for mounting a portion of the bracelet. Small size high-density screws (to reduce the play between the pushers and the hooking system also involve high machining costs).

Patent No. GP 2 340 168 discloses a wrist fastener comprising two hinged loops that connect the generally H-shaped stretcher-like structure to the bracelet hinge lines. Opening the fastener requires pushing The button releases the closure ring, and the push button includes a housing for a return element formed by a spring. As with the fasteners described above, the fastener has a generally H-shaped support plate for holding the push buttons to abut the H-shaped stretcher-like structure. The inner mask of the support plate at its cross arm of H has a contour for holding the spring element. Manufacturing difficulties and machining costs are similar to those described above. The precise arrangement of the springs in the push buttons for allowing the fastener to be opened and closed by pressing the push buttons toward the other is a complicated operation for Reduce any possible play between the two push buttons.

European Patent No. 1,247,469 discloses a fastener comprising a stretcher-like structure, a folding arm and a detachable button, the stretcher-like structure comprising two pushers that are moved against the crushing of a return element In the opposite direction, the folding arm or the detachable button is respectively locked or released relative to the stretcher-like structure when the fastener is closed or opened. The complexity of this fastener lies in the alignment of the two pushers because the relationship of the guides and the guide housing that are inserted between the two return elements (springs) in an abutting manner is used. When the two pushers are moved together, the guide and the guide housing are inserted into the pushers to reduce the play which is required to be manufactured with high precision. The return elements must have the same characteristic configuration such that during the relative movement of the two push members against the compression of the two return elements, the guides are within the guide housing of one or the other of the push members The position is substantially the same for both pushers.

In these known fasteners, each pusher has some play with respect to the moving area formed by the stretcher-like structural wall and the support plate. The way is moved. The total movement gap of the two pushing members may cause incomplete meshing of the locking mechanism of the folding arm (especially the hook and the groove) and the complementary locking mechanism (ie, the groove or the hook) of the pushing member or the other pushing member. The shape of the support plate becomes extremely important. Therefore, the accidental unlocking and opening of the fastener cannot be ruled out, which causes the loss of the watch, which is unacceptable for the advanced watch.

The common manufacturing difficulties associated with these known inventions include minimizing the play between such pushers while requiring a high quality appearance and attractiveness to present a luxurious watch or jewel, which requires strict manufacturing. Margin, so it is very expensive.

It is an object of the present invention to provide a high security closure fastener that can be manufactured using inexpensive manufacturing methods that are simpler than conventional techniques.

Accordingly, there is a need for fasteners that can avoid play between push buttons and that have an improved opening and closing system.

The search for a simpler construction must contribute to the manufacture of various small-sized components, especially the use of support and hooking mechanisms that are simpler and less expensive than precision screws.

Accordingly, the present invention relates to a fastener for a piece of jewelry or a wristwatch, comprising a stretcher-like structure having a first outer casing in which a first pusher and a second pusher are resistant An elastic return mechanism is moved relative to each other on a first bearing surface, and the first pushing member and the second pushing member retained by the at least one cover plate in the first housing can occupy a cover position of a second outer casing, characterized in that the fastener comprises at least one elastic locking member for the cover plate, the elastic lock member comprising a button and being held in the stretcher-like structure and On the one hand, in a compressed position, it is arranged to move with the at least one cover plate, and on the other hand, in a relaxed position, by the button and a fourth outer casing contained in the at least one cover plate Cooperate to secure the at least one cover in the cover position.

The invention also relates to a wristband comprising at least one fastener of this type.

The invention also relates to a wristwatch comprising a wristband of this type.
