Description
La présente invention concerne un fermoir ajustable pour montre.The present invention relates to an adjustable clasp for a watch.
La présente invention concerne également une montre-bracelet munie d'un tel fermoir.The present invention also relates to a wristwatch provided with such a clasp.
La problématique relative à la nécessité de prévoir un dispositif de réglage de la longueur d'un bracelet est bien connue.The problem relating to the need to provide a device for adjusting the length of a bracelet is well known.
Il est connu d'utiliser un fermoir qui reste solidaire des extrémités des deux brins de bracelet. Un tel fermoir occupe deux position : une position fermée, prévue pour le port de la montre, dans laquelle le bracelet et le fermoir s'étendent sur le pourtour du poignet en présentant une longueur totale permettant le maintien de la montre, et une position ouverte ou déployée qui permet d'augmenter la longueur du fermoir et donc du bracelet pour permettre le passage de la main et le retrait de la montre.It is known to use a clasp which remains attached to the ends of the two bracelet strands. Such a clasp occupies two positions: a closed position, provided for wearing the watch, in which the strap and the clasp extend around the circumference of the wrist, having a total length allowing the watch to be held, and an open position. or deployed which increases the length of the clasp and therefore of the bracelet to allow passage of the hand and removal of the watch.
Dans une solution avec fermoir, un premier objectif est la recherche d'un confort optimal lors du porter du bracelet. Pour cela, il est avantageux que le fermoir épouse au mieux le contour d'un poignet, d'un grand comme un petit poignet, lorsque le fermoir est en configuration fermée. Une difficulté dans la réalisation d'un fermoir consiste donc à proposer un fermoir épousant de manière adéquate et confortable le poignet d'un porteur d'une montre-bracelet quelles que soient les dimensions du poignet du porteur.In a solution with clasp, a first objective is the search for optimal comfort when wearing the bracelet. For this, it is advantageous for the clasp to best match the contour of a wrist, of a large as well as a small wrist, when the clasp is in the closed configuration. A difficulty in the production of a clasp therefore consists in proposing a clasp fitting in an adequate and comfortable manner the wrist of a wearer of a wristwatch whatever the dimensions of the wrist of the wearer.
A titre d'exemple, la demande de brevet
Toutefois, un tel dispositif de réglage de la longueur du bracelet est peu esthétique étant donné que les trous de réglage sont visibles sur les côtés du capot. En outre, l'opération de réglage d'un tel fermoir requiert une certaine dextérité car elle nécessite d'introduire un outil pointu dans les trous pour comprimer la barrette de fixation du bracelet, ce qui risque de conduire à des dommages au niveau du capot en cas de maladresse de la personne réalisant l'ajustement.However, such a device for adjusting the length of the bracelet is unattractive since the adjustment holes are visible on the sides of the cover. In addition, the adjustment operation of such a clasp requires a certain dexterity because it requires introducing a pointed tool into the holes to compress the bracelet fixing strip, which risks leading to damage to the cover. in case of clumsiness of the person making the adjustment.
Pour éviter une telle situation, des dispositifs alternatifs ont déjà été divulgués, comme par exemple dans le brevet
De telles solutions présentent toutefois les inconvénients de complexifier la construction, d'augmenter son encombrement et de rendre difficile la manipulation du fermoir.Such solutions, however, have the drawbacks of making the construction more complex, of increasing its size and of making it difficult to manipulate the clasp.
Un but principal de la présente invention est de pallier les inconvénients des fermoirs connus de l'art antérieur, en proposant un fermoir de bracelet permettant d'offrir un bon confort au porter quelle que soit la taille du poignet.

Avantageusement, les articulation A1, A2 sont délimitées angulairement par des butées respectivement formées sur la première extrémité des première et seconde lames 1,2 et sur la seconde extrémité des mobiles 3, 4 de manière à définir deux positions de porter prédéfinies, à savoir une position de porter pour les petits poignets et une position de porter pour les grands poignets.Advantageously, the joints A1, A2 are angularly delimited by stops respectively formed on the first end of the first and
Chacune des articulations A1 et A2 est délimitée angulairement par des butées 10a, 10b, 21a, 21b des première et seconde lames 1, 2, coopérant avec des butées correspondantes 30a,30b,40a,40b des lames mobiles 3, 4. Ces butées définissent les première et seconde positions des lames mobiles 3, 4, et implicitement du fermoir, dans lesquelles les deux lames occupent toutes les deux la même position.Each of the joints A1 and A2 is angularly delimited by
Les lames mobiles 3, 4 peuvent ainsi occuper une première position adaptée aux petits poignets et une seconde position adaptée aux grands poignets, lorsque le fermoir est fermé. Le passage d'une position à l'autre se fait naturellement lorsque la montre est portée grâce aux butées.The
De manière à pouvoir fournir un fermoir adapté à un grand nombre de morphologie de poignets, l'amplitude du débattement angulaire des articulations A1, A2 est compris, par exemple, entre 5° et 35°.
