AUTOMATIC ELECTRO-MAGNETIC LOCKING LOCK FOR THE SLIDING ROD OF A MULTI-POINT LOCK.

Abstract

L'invention concerne un verrou de condamnation d'une tringle 3,3' ou d'un des pénes intermédiaires 13,13' de serrure existante 2 par le déplacement d'un embout 6 solidaire d'un électro-aimant 8 en position verticale. Lors de la fermeture de la serrure 2, entraînant le déplacement du pène intermédiaire 13 l'embout 6 se positionne à l'arrière de celui-ci. Une butée existante ou rapportée 14 s'opposera alors au déplacement du pène intermédiaire. L'ouverture de la porte s'effectue par l'émission de un ou plusieurs codes en provenance du clavier 12 monté sur la partie extérieure de la porte 1 et commandant l'électro-aimant 8, ce qui permet la libération et le déplacement du péne intermédiaire 13 car le mouvement de la clé de la serrure 2. Il est entendu qu'une disposition identique pourrait être adoptée pour le pène intermédiaire 13'.

Description

The purpose of this addition is to provide an improvement to the Main patent relating essentially to the improvement of the intervention conditions of the electromagnet connected to the electronic control. We will describe below this improvement with reference to the attached drawing in which Figure 1 represents a door to which the means of addition are applied, while Figure 2 represents in enlarged view a detail of Figure 1. Figure 1 is a perspective view representing a door 1, interior side, equipped with a key lock, with conventional mechanical operation 2, transmitting vertical movements to two demitringles 3,3' acting on two bolts 13,13', the door is also provided with a fixed stop 11, and an electromagnet 8 connected to an electronic control keypad 12 by programmed code, located on the exterior part of the door. The electromagnet has the particularity, for the improvement of its operation, of not being in a cantilevered position, such as the horizontal position, and of not acting directly on the rod 3,3' so that it avoids being subjected to a shear force. I1 therefore acts indirectly, as an intermediary, vertically, by its mobile part, and jointly with the fixed stop 11, so that the tip 6 is interposed between a bolt 13 of the mechanical lock and the said fixed stop.By this means, we simplify the double opening control in the case of a locking system with more than three points, and increase its reliability. Figure 2 shows a detail of Figure 1. On this detail, a means 14 allows, manually, the release of the bolt 13 and the tip 6 for unlocking the door, on the inside. The operation is identical to that of the Main Patent. The opening of door 1 is achieved by the emission of one or more codes from the computerized keypad 12 located on the outside side of door 1, which controls the electromagnet 8, allowing the release and movement of the intermediate bolt 13 by the operation of the key in the lock 2. It is understood that a provision identical to the one that follows to be described could be adopted for the 13t penile.

Claims

DEMANDS X, Automatic locking device using an electromagnet for the sliding rod of a multipoint residential door lock, the unlocking of which is achieved via an external keypad with numeric or alphanumeric control emitting a timed electronic pulse on an internal circuit, acting on the electromagnet, which allows the key to rotate to open the door, according to claim 1 of the main patent, characterized in that the movable part integral with the vertically arranged electromagnet (8) is interposed between the bolt (13) of a mechanical lock and an independent fixed stop L1 mounted on the door.

2. Automatic locking device according to claim 1, characterized in that the movable and protruding part (6) of the electromagnet comprises an end piece (6) provided with a lever (14) allowing manual actuation of said movable part (6) from the inside, in order to manually disengage the bolt (13). the tip (6) for unlocking the note.

3. Automatic locking device according to claim 1, characterized in that the electromagnet (8) and the stop (11) are attached to the door (1) inside side.
