Description

<U>Serrure à came batteuse</U> La présente invention concerne une serrure came batteuse du type comprenant un rotor tourillonnant dans un stator sous l'action d'une clé, ledit stator étant monté dans une ouverture d'un support et la came étant solidaire du rotor. De manière habituelle, dans ce type de serrure, le stator est un cylindre, pourvu de deux plats opposés, qui se loge dans un ajour du support de forme complémentaire, une collerette extérieure du stator venant en butée contre le bord périphérique de l'ajour sur une face du support. De manière à bloquer le stator dans l'ajour, le cylindre comporte un filetage à sa surface extérieure qui permet l'engagement d'un écrou qui vient se serrer contre le bord périphérique de l'ajour sur la face opposée du support de manière à bloquer la serrure dans l'ajour. The present invention relates to a cam lock cam of the type comprising a rotor journalled in a stator under the action of a key, said stator being mounted in an opening of a support and the cam being integral with the rotor. Usually, in this type of lock, the stator is a cylinder, provided with two opposing plates, which is housed in an aperture of the complementary shaped support, an outer collar of the stator abutting against the peripheral edge of the aperture on one side of the support. In order to block the stator in the opening, the cylinder has a thread on its outer surface which allows the engagement of a nut which is tightened against the peripheral edge of the aperture on the opposite face of the support so as to lock the lock in the ajour.

Des serrures de ce type sont utilisées en particulier pour des boîtiers d'ordinateur pour lesquels les évolutions et les modifications sont nombreuses. Aussi, ce type d'assemblage de la serrure sur le support, relativement lent à mettre en oeuvre n'est plus adapté. Ainsi, l'invention a pour but de proposer une serrure à came batteuse dont le montage sur le support est simple, rapide et donc économique. Locks of this type are used in particular for computer cases for which changes and modifications are numerous. Also, this type of assembly of the lock on the support, relatively slow to implement is no longer suitable. Thus, the object of the invention is to propose a cam lock whose mounting on the support is simple, fast and therefore economical.

A cet effet, l'invention a pour objet une serrure à came batteuse du type comprenant un rotor tourillonnant dans un stator sous l'action d'une clé, ledit stator ou corps de serrure de forme cylindrique, de préférence comportant un filetage à sa surface, étant destiné à se loger dans une ouverture de forme complémentaire ménagée dans un support, ledit corps de serrure comportant une collerette frontale en appui autour du bord extérieur de ladite ouverture en position de montage, caractérisée en ce que le corps de serrure comporte au moins un moyen d'encliquetage coopérant avec un moyen d'encliquetage complémentaire ménagé sur une pièce bordant le bord intérieur de l'ouverture, la coopération desdits moyens d'encliquetage étant assurée lors de la mise en appui de la collerette frontale sur le support. Ainsi, de manière avantageuse, lorsqu'on met en place corps de serrure sur le support, la collerette frontale vient en appui sur le bord extérieur de l'ouverture du support tandis que, de l'autre côté de l'ouverture, le moyen d'encliquetage du corps de serrure coopère avec le moyen d'encliquetage complémentaire ménagé sur la pièce bordant le bord intérieur de ladite ouverture, la collerette étant ainsi serrée contre le support. For this purpose, the subject of the invention is a cam lock of the type comprising a rotor journalled in a stator under the action of a key, said stator or lock body of cylindrical shape, preferably having a thread at its end. surface, being intended to be housed in an opening of complementary shape formed in a support, said lock body comprising a front flange resting around the outer edge of said opening in the mounting position, characterized in that the lock body comprises at less a latching means cooperating with a complementary latching means provided on a piece bordering the inner edge of the opening, the cooperation of said latching means being ensured when the front flange bears against the support. Thus, advantageously, when lock body is placed on the support, the front collar bears on the outer edge of the opening of the support while, on the other side of the opening, the means latching the lock body cooperates with the complementary latching means provided on the piece bordering the inner edge of said opening, the collar being thus clamped against the support.

Selon une forme de réalisation préférée de l'invention, pièce bordant le bord intérieur de l'ouverture est de forme tubulaire, au moins une patte élastiquement déformable étant ménagée dans la paroi tubulaire et dont l'extrémité libre est en saillie à l'intérieur de la pièce tubulaire, le moyen d'encliquetage complémentaire du corps de serrure étant constitué par une cavité ménagée dans ledit corps de serrure dans laquelle se loge l'extrémité libre de patte en position de montage. According to a preferred embodiment of the invention, part bordering the inner edge of the opening is of tubular shape, at least one elastically deformable tab being formed in the tubular wall and whose free end is projecting inside. of the tubular piece, the complementary latching means of the lock body being constituted by a cavity formed in said lock body in which is housed the free end of the tab in the mounting position.

corps de serrure peut être cylindrique section circulaire ou il peut comporter des plats opposés comme cela est connu. De même, ce corps de serrure peut comporter un filetage à sa surface de manière à autoriser également un montage classique par écrou. lock body may be cylindrical circular section or it may comprise opposite dishes as is known. Similarly, this lock body may have a thread on its surface so as to also allow a conventional mounting nut.

La pièce tubulaire peut être réalisée d'une seule pièce avec le support, type monobloc. En variante, la pièce tubulaire peut être rapportée sur le support à la périphérie de 'ouverture. The tubular piece can be made in one piece with the support, monobloc type. In a variant, the tubular piece may be attached to the support at the periphery of the opening.

Ainsi, une serrure selon l'invention peut être utilisée pour equiper au besoin des matériels informatiques lors de renouvellements d'outillage, lors de lancements de nouveaux produits, pour des gains de productivité, etc., qui doivent etre condamnés, par simple mise en place d'une pièce bordant le bord intérieur de l'ouverture du support. Ainsi, lorsque corps de serrure comporte un filetage, il peut très bien avoir été monté avec un écrou de manière classique puis il peut être monté selon l'invention par simple mise place de pièce tubulaire sur le support. Thus, a lock according to the invention can be used to equip the hardware if necessary during tooling renewals, during new product launches, for productivity gains, etc., which must be condemned, by simple implementation. place of a piece bordering the inner edge of the opening of the support. Thus, when the lock body has a thread, it may very well have been mounted with a nut in a conventional manner and then it can be mounted according to the invention simply by placing a tubular piece on the support.

On décrira maintenant l'invention plus en détail référence au dessin dans lequel la figure unique représente une vue schématique en perspective d'une serrure selon un exemple de réalisation de l'invention.
