Description

CLASP FOR PIECE OF JEWELERY OR WRISTWATCH FOR PART OF JEWELRY OR WRIST

The present invention relates to an article of manufacture for a piece of jewelry or a wristwatch comprising a stretcher-type structure in which the first push-piece and the second push-piece have a first housing movable relative to each other on the first bearing surface against the elastic return means The first push-piece and the second push-piece are retained in the first housing by at least one closing plate that can assume a closed position in the second housing.

The invention also relates to a bracelet comprising at least one class of this type.

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

The present invention relates to the field of watchmaking, jewelry and more specifically wrist watches and bracelets.

Numerous Classp variations are used in watchmaking and jewelry to open and close bracelets, especially watch bracelets. These clips enable the bracelet strands to be held in a combined position to be engaged and forming a practical fixation. The bracelet strands are generally hinged at the ends of the lockable foldable arms and the lockable foldable arms are in turn hinged at the ends of the stretcher-type structure with locking means complementary to the locking means of the foldable arms. The arms can be unlocked by force-piece elements, advantageously force or advantageously. These clasps typically have push-pieces that can be moved in opposite directions relative to the stretcher-like structure against compression of the return element to lock or unlock the folding arm when the closure is closed or open.

FR Patent No. 2825244 discloses a foldable bracelet class with a push-piece including a profiled, generally H-shaped stretcher-like structure, and an H-shaped stretcher-type structure for push- A return element arrangement formed by a strip spring, and mounting arrangements for two opposed push-pieces. The support plate has push-pieces, strip springs and a hooking system for the stretcher-like structure to open and close the clasp. The H-shaped support plate also has two symmetrical hollows bounded by parallel branches for the mounting arms with hinge-like mounting arrangements against portions of the bracelet, opposite the hinge portion. The H-shape of the support plate and the stretcher-type structure generally results in machining complexity that becomes more expensive due to the presence of four housings for precision screws. These holes must be centered and aligned with great accuracy on the H-shaped parallel bars, and the arrangement of the strip springs in the H-shaped crossbar is very complex; This allows for the mounting and operation of the two push-pieces and the assembly of two parallel branches for mounting one part of the bracelet. High-precision screws of small dimensions (to reduce the clearance between the push-pieces and the hooking system) also include increased machining costs.

GP Patent No. 2340168 discloses a wristwatch class including two swivel loops connecting an H-shaped stretcher-like structure to bracelet strands in general. The opening of the clasp requires a closed loop to be released by squeezing the push-buttons including the housing for the return element formed by the spring. Similar to the previous class, this classp also has a generally H-shaped support plate to hold the push-buttons for the H-shaped strainer-like structure. This support plate has a profile of its inner surface on the H-shaped cross-branch to retain the spring element. The difficulties and machining costs are similar to those described above. The spring arrangement and alignment for its precise positioning in the push-buttons, which allows the class to be opened and closed by compressing one push-button for another, Lt; / RTI >

EP Patent No. 1247469 discloses a class including a stretcher-type structure, a folding arm, and a removable button, and the stretcher-type structure comprises a removable button or foldable structure for the stretcher-type structure when the class is closed or open, Pieces that can be moved in opposite directions against the compression of the return element to lock or unlock the arm. Such a clasp has the complexity of the use of guide elements inserted adjacent between two return elements (springs) and the alignment of the two push-pieces due to their guide housings. High accuracy manufacturing is required to insert guiding elements and housings into the push-pieces and to reduce the clearance when the two push-pieces are moved together. The return elements must have the same features so that the position of the guiding element in one or the other guiding housing of the push-pieces is substantially the same for both push-pieces during its relative movement against compression of the two return elements.

In these known classpiles, each push-piece is moved with slight clearance to the moving section formed by the strainer-like structure walls and the support plate. The combined movement clearances of both push-pieces cause incomplete engagement of the complementary locking means, in particular the hooks or grooves of the locking means, in particular of the folding arms, with the respective grooves or hooks of one push-piece or other push- So that the geometry of the support plate is very important. It is therefore not possible to exclude the unintentional unlocking and opening of the clasp, which can result in a loss of the watch that is not allowed for the luxury watches.

The manufacturing difficulties common to these known inventions are to minimize the clearance between the push-pieces requiring a high degree of appearance and attention, which is characteristic of high-grade wrist watches or jewelry, while requiring strict manufacturing tolerances, It is expensive.

It is an object of the present invention to devise Classes having a high stability lock that can be manufactured by simpler, economical manufacturing methods than the prior art.

There is therefore a need for an improved clasp that avoids clearance between push-buttons and has an improved open and closed system.

Research into simpler configurations should facilitate the manufacture of various components of small dimensions, especially by using a simpler and cheaper support and hooking means than precision screws.

The invention therefore relates to an article of jewelry or a wrist watch comprising a stretcher-like structure having a first housing in which the first push-piece and the second push-piece are movable relative to each other on the first bearing surface against the elastic return means Said first push-piece and said second push-piece being held in said first housing by at least one closing plate capable of taking a closed position in a second housing, said first push-piece and said second push- And at least one resilient locking element for the closing plate, wherein the resilient locking element comprises a push-button and is retained in the strainer-like structure, while at the same time, In the compressed position and on the other hand, the fourth housing, which is included in said at least one closing plate, And is arranged in a relaxed position that disables movement of the at least one closing plate in the closed position through co-operation of the pre-push-button.

Embodiments of the invention are illustrated in the description and illustrated in the accompanying drawings:
