Description
La présente invention concerne une serrure de bâtiment dont un pêne est maintenu en position fermée par un ressort.The present invention relates to a building lock, a bolt of which is held in the closed position by a spring.
Les serrures de bâtiment les plus utilisées comportent un pêne rentrant en biseau, appelé pêne demi-tour, destiné à maintenir la porte fermée, et un pêne de forme parallélépipédique, actionné par une clé ou un bouton de condamnation, destiné à condamner la fermeture. Pour les portes ou portail coulissants, le pêne rentrant en biseau est souvent remplacé par un pêne levant à crochet, dont le biseau est horizontal. Ces pênes coopèrent avec une gâche positionnée sur le cadre de la porte, cette gâche comportant autant de trous que de pênes, et de forme adaptée à ces pênes ?The most commonly used building locks include a beveled re-entrant bolt, called a half-turn bolt, intended to keep the door closed, and a parallelepiped-shaped bolt, operated by a key or a locking button, intended to lock the closure. For sliding doors or gates, the beveled re-entrant bolt is often replaced by a hooked lifting bolt, the bevel of which is horizontal. These bolts cooperate with a striker positioned on the frame of the door, this striker having as many holes as bolts, and of a shape adapted to these bolts?
Lors de l’ouverture de la porte, le pêne demi-tour est entraîné vers l’intérieur du coffre de la serrure par le fouillot, lui-même actionné par le carré d’une poignée, ou béquille. Lors de la fermeture, lorsque le pêne arrive en appui sur le bord de la gâche, ce pêne s’efface à l’intérieur du coffre de la serrure par la pression exercée sur le biseau. Le pêne compresse ainsi un ressort dans le coffre de la serrure. Dès que la pointe du biseau débouche dans le trou de la gâche, le ressort repousse le pêne vers l’extérieur du coffre, assurant ainsi le maintien de la porte en position fermée. Dans le cas d’un pêne levant à crochet, le principe est identique, à la différence que le pêne, solidaire du fouillot, au lieu de rentrer dans le coffre, se soulève sous la pression du biseau, réalisé horizontalement, et vient s’accrocher derrière la gâche.When the door is opened, the latch bolt is drawn towards the inside of the lock case by the follower, itself actuated by the square of a handle, or crutch. When closing, when the bolt comes to rest on the edge of the striker plate, this bolt is erased inside the lock case by the pressure exerted on the bevel. The bolt thus compresses a spring in the case of the lock. As soon as the point of the bevel opens into the hole in the striker plate, the spring pushes the bolt towards the outside of the safe, thus ensuring that the door is held in the closed position. In the case of a lifting bolt with hook, the principle is identical, with the difference that the bolt, integral with the follower, instead of entering the trunk, is raised under the pressure of the bevel, carried out horizontally, and comes hang behind the strike.
Un inconvénient de ce type de serrure vient du fait que le ressort qui repousse le pêne en position de fermeture fatigue dans le temps, voire casse, rendant la fermeture moins sûre ou même impossible. De plus ce ressort est souvent la cause de grincements désagréable lors de la manipulation de la serrure.A disadvantage of this type of lock comes from the fact that the spring which pushes the bolt back into the closed position wears out over time, or even breaks, making closing less secure or even impossible. In addition, this spring is often the cause of unpleasant squeaks when handling the lock.
Le dispositif selon l’invention permet de remédier à ces inconvénients. La force de rappel du ressort est remplacée par la force que présente l’opposition de deux masses magnétiques antagonistes positionnées et orientées dans la serrure, l’une à l’arrière du pêne, l’autre sur la paroi du coffre de la serrure, de façon à ce que leurs pôles se repoussent réciproquement, entrainant ainsi le pêne dans sa position de fermeture..The device according to the invention makes it possible to remedy these drawbacks. The return force of the spring is replaced by the force presented by the opposition of two antagonistic magnetic masses positioned and oriented in the lock, one at the rear of the bolt, the other on the wall of the lock case, so that their poles repel each other, thus driving the bolt into its closed position.
Selon des modes particuliers de réalisation :
- Les masses magnétiques sont constituées par deux aimants permanents, l’un étant fixé à l’arrière du pêne, l’autre sur le coffre de la serrure.
- Les aimants peuvent être collés, ou vissés, ou encore logés dans des espaces aménagés dans le pêne et la serrure, en particulier lorsque ceux-ci sont obtenus par moulage.
- A titre purement indicatif, une force de répulsion de 10 N, obtenue avec des aimants de petite taille, est suffisante pour cette application.According to particular embodiments:
- The magnetic masses consist of two permanent magnets, one being fixed to the back of the bolt, the other to the lock case.
- The magnets can be glued, or screwed, or housed in spaces provided in the bolt and the lock, in particular when these are obtained by molding.
- For information only, a repulsion force of 10 N, obtained with small magnets, is sufficient for this application.
Les dessins annexés illustrent l’invention :The accompanying drawings illustrate the invention:
Fig.5] représente une vue de la même serrure en position ouverte.Fig.5] shows a view of the same lock in the open position.
En référence à ces dessins, Les serrures sont composées d’un coffre (1), d’un pêne (2), actionné par un fouillot (3) comportant un trou carré (4) dans lequel vient se loger le carré de la poignée de porte (non représentée) pour effectuer la manœuvre d’ouverture. Dans le cas de la serrure à pêne levant, le pêne et le fouillot sont une même pièce.With reference to these drawings, the locks are made up of a box (1), a bolt (2), actuated by a follower (3) comprising a square hole (4) in which the square of the handle is housed door (not shown) to perform the opening operation. In the case of the lifting bolt lock, the bolt and the follower are the same part.
Un aimant (5) est fixé sur la face arrière du pêne (2). Un autre aimant (6) est fixé contre la paroi du coffre (1) de la serrure. Le cas illustré par les figures montre que les pôles Sud, notés S, des aimants sont placés face à face afin d’exercé une force de répulsion. Le même résultat serait obtenu en opposant les pôles Nord, notés N.A magnet (5) is fixed on the rear face of the bolt (2). Another magnet (6) is fixed against the wall of the box (1) of the lock. The case illustrated by the figures shows that the South poles, denoted S, of the magnets are placed face to face in order to exert a repulsion force. The same result would be obtained by opposing the North poles, denoted N.
