Description
<Desc/Clms Page number 1>
Dispositif de sécurité pour serrures. @ Dans la plupart des serrures actuelles le fait de laisser la clef engagée dans la serrure ne constitue pas une sécurité absolue car il reste toujours possible de faire tourner la clef et de la repousser hors de la serrure et ensuite d'y introduire une autre clef .
Dans le but de remédier à cet inconvénient l'invention prévoit d'utiliser un organe qui empêche ce déplacement longi- tudinal de la clef .
De plus le même organe est établi de façon à s'opposer à la rotation de la clef .
Cet organe est suivant l'invention constitué par une plaque mobile se déplaçant dans la trajectoire de la lame de la clef . A l'effet de s'opposer à la rotation de la clef cette plaque est pourvue d'une partie en forme de came qui tend à coincer obliquement la tige dans la serrure .
L'invention s'étend aux diverses façons de disposer la dite plaque ainsi qu'aux produits nouveaux résultant de la combinaison de cette plaque avec les serrures ou les plaques d'entrée de, serrures .
Les dessins annexés indiquent à titre d'exemple non

La fig.l est une vue en coupe partielle à travers une serrure .
La fig.2 est une vue de face de la plaque d'entrée de cette serrure .
Une serrure 2 encastrée dans la porte 3 ,parte des ouvertures d'entrée 2a et 2b permettant l'introduction d'une clef 4 . Entre la plaque d'entrée 5 et le bois de la porte est disposée une plaque mobile 6 pivotant en 6a sur la plaque 5 . Cette plaque est munie d'une rainure 6b en forme de came qui 'agit par sa face inférieure pour soulever la clef dans le sens de la flèche A et la coincer dans la serrure ; le frottement résultant de ce

Il va de soi que la plaque mobile 6 peut être dis- posée sur la face extérieure de la plaque d'entrée 5. De même elle peut être prévue directement sur les faces de la serrure ; dans ce cas on prévoit une rainure dans le bois de la porte afin de permettre le passage d'un bouton tel que 4f.
REVENDICATIONS.
1. Dispositif de sécurité pour serrure consistant en un organe empêchant le déplacement longitudinal (sortie de la clef) dans la serrure .

Security device for locks. @ In most current locks, leaving the key engaged in the lock does not constitute absolute security because it is always possible to turn the key and push it out of the lock and then insert another key. .
In order to remedy this drawback, the invention provides for the use of a member which prevents this longitudinal displacement of the key.
In addition, the same organ is established so as to oppose the rotation of the key.
This member is according to the invention constituted by a movable plate moving in the path of the blade of the key. In order to oppose the rotation of the key, this plate is provided with a part in the form of a cam which tends to wedge the rod obliquely in the lock.
The invention extends to the various ways of arranging said plate as well as to new products resulting from the combination of this plate with the locks or the entry plates of the locks.
The accompanying drawings show by way of example no

limiting one embodiment of the invention. This extends to the various original features included in the arrangement shown.
Fig.l is a partial sectional view through a lock.
Fig.2 is a front view of the entry plate of this lock.
A lock 2 embedded in the door 3, leaves the entry openings 2a and 2b allowing the introduction of a key 4. Between the entry plate 5 and the wood of the door is arranged a movable plate 6 pivoting at 6a on the plate 5. This plate is provided with a groove 6b in the form of a cam which acts through its underside to lift the key in the direction of arrow A and jam it in the lock; the friction resulting from this

, 0 * - CLU <'' 2c / U-P 'jam being sufficient-to oppose on end 4a of this key. The tab 6d of the plate is against any exit of the key from the lock. The engagement and removal of the plate is controlled by a button 4f.
It goes without saying that the movable plate 6 can be placed on the exterior face of the entry plate 5. Likewise it can be provided directly on the faces of the lock; in this case, a groove is provided in the wood of the door to allow the passage of a button such as 4f.
CLAIMS.
