Abstract

The invention concerns a watch whereof the bracelet is fixed to the middle (5) through a system of retractable pins (10) driven in the end link (4) and slides (2) housed in the horns (7) of the middle (5). The slides (2) simultaneously actuated along the arrow (A) act as extractors pushing back the pins (10) inside the case (1) when the link (4) is locked. When the bracelet is assembled, the link (4) is located beneath the horns (7). By generating a vertical movement from down upwards along the arrow (B), the pins (10) are engaged into the ramp (3) and are retracted inside the housing of the case (1) under the action of the inclined ramp (3), the pins are released inside the hole of the barrel (8) thereby locking the link (4) between the horns (7) of the middle.

Description

Fermeture rapide pour bracelet-montre Quick closure for watch strap

Introduction : Le bracelet métallique ou tout autre bracelet cuir, plastique qui prolonge la carrure de la montre est très souvent composé de deux branches articulées autour des axes de fixation (pompes) entre les cornes de la carrure et d'une boucle classique ou dépliante réunissant les deux branches. La boucle classique est simple mais peu esthétique, la boucle dépliante quant à elle est bien souvent compliquée à réaliser si elle doit être réglable.Introduction: The metal strap or any other leather, plastic strap that extends the middle of the watch is very often composed of two branches articulated around the fixing pins (pumps) between the horns of the middle and a classic or folding buckle bringing together the two branches. The classic buckle is simple but unattractive, the folding buckle is often complicated to realize if it has to be adjustable.

L'invention décrite ici supprime complètement la boucle si le styliste estime que le bracelet peut constituer un objet d'art à lui-seul . Le bracelet est donc plus simple, d'un seul morceau, l'accrochage se faisant alors par le dernier maillon terminal et la carrure.The invention described here completely eliminates the loop if the stylist considers that the bracelet can constitute an art object in itself. The bracelet is therefore simpler, in one piece, the attachment then being made by the last terminal link and the middle part.

Pour la compréhension du texte et des dessins c'est un bracelet métallique qui a été représenté.For the understanding of the text and the drawings, a metallic bracelet was represented.

Description de l'invention : La Fig.l représente la carrure (5) de la montre et de son bracelet métallique (6). A chaque extrémités de la carrure (5) se prolongent les cornes (7).Description of the invention: Fig.l shows the middle part (5) of the watch and its metallic bracelet (6). At each end of the middle part (5), the horns (7) extend.

Entre les cornes vient s'ajuster le maillon terminal (4) de chaque coté de la carrure Fig.3.Between the horns comes adjust the end link (4) on each side of the middle part Fig.3.

Afin de retenir le maillon terminal du bracelet dans l'ouverture de la carrure il a été pratiqué un perçage à l'intérieur de chaque corne (7) afin d'y loger le canon (8) et le poussoir(2) repoussé vers l'extérieur de la carrure par un ressort (9) Fig.5, ce poussoir (2) est logé dans les cornes (7) de la carrure (5) .In order to retain the terminal link of the bracelet in the opening of the middle part, a hole was drilled inside each horn (7) in order to accommodate the barrel (8) and the pusher (2) pushed towards the exterior of the middle by a spring (9) Fig.5, this pusher (2) is housed in the horns (7) of the middle (5).

Dans le maillon terminal (4) on pratique un trou de chaque coté pour permettre le chassage de l'étui (1) dégageant l'ergot rétractable (10) repoussé par le ressort logé dansIn the end link (4) a hole is made on each side to allow the casing (1) to be driven out, releasing the retractable lug (10) pushed back by the spring housed in

l'étui (1) Fig.4.the case (1) Fig. 4.

Sur les cornes (7) on vient également pratiquer une petite saignée inclinée (3) permettant la rentrée de l'ergot rétractable (10) cette rampe est suffisamment inclinée pour repousser. les ergots (10) dans leur étui(l) et permettre le passage du maillon (4) entre les cornes (7) et venir se positionner dans le trou du canon (8) pour le verrouillage Accrochage du bracelet : Après avoir mis le bracelet à la longueur du poignet en enlevant ou en ajoutant des maillons, le maillon terminal (4) est présenté sous les cornes (7) de la carrure (5) et il est remonté :voir flèche(B) Fig.3 jusqu'à ce que l'ergot (10) s'encastre le long de la rampe inclinée de la saignée (3) de la corne (7) et sous l'effet du plan incliné l'ergot (10) rentre à l'intérieur de l'étui (1) Fig.l . En fin de course du maillon terminal (4), l'ergot (10) rencontre le trou du canon (8) Fig.5 et se libère sous l'effort du ressort logé dans l'étui (1), bloquant aussi le maillon (4) en position verrouillée. Décrochage du bracelet :I1 suffit pour désolidariser le maillon terminal (4) des cornes (7) et de la carrure (5) de presser simultanément les deux poussoirs (2) d'un côté ou de l'autre de la carrure (5) suivant les flèches (A) provoquant la rentrée des ergots (10), dégageant ainsi la retenue dans l'étui (1) et la libération du maillon terminal (4). On the horns (7) one also comes to practice a small inclined groove (3) allowing the retraction of the retractable lug (10) this ramp is sufficiently inclined to push back. the lugs (10) in their case (l) and allow the passage of the link (4) between the horns (7) and come to be positioned in the hole of the barrel (8) for locking Attachment of the bracelet: After having put the bracelet at the wrist length by removing or adding links, the terminal link (4) is presented under the horns (7) of the middle part (5) and it is reassembled: see arrow (B) Fig. 3 until that the lug (10) is fitted along the inclined ramp of the groove (3) of the horn (7) and under the effect of the inclined plane the lug (10) enters inside the case (1) Fig. l. At the end of the travel of the terminal link (4), the lug (10) meets the hole in the barrel (8) Fig. 5 and is released under the force of the spring housed in the case (1), also blocking the link (4) in the locked position. Unhooking the bracelet: I1 is sufficient to separate the terminal link (4) from the horns (7) and the middle part (5) to press simultaneously the two pushers (2) on one side or the other of the middle part (5) according to the arrows (A) causing the lugs (10) to retract, thus releasing the retention in the case (1) and the release of the terminal link (4).

Claims

-1- Set composed of a watch middle part (5) Fig.l whose horns (7) Fig.2 are machined to receive four pushers (2) Fig.5 which act as pistons during unlocking associated with two inclined ramps (3) Fig.3 allowing the retraction of the pins (10) Fig.4 before locking them in the barrel hole housing (8) Fig.5 of the horn (7).

-2- The assembly of claim -1- characterized in that the pushers (2) Fig.l must be actuated simultaneously to ensure the unlocking of the link (4). -3- An assembly according to claims -1-2- characterized in that the end links (4) can be combined with a flexible bracelet with two branches associated with a conventional closure loop
