Title (EN) SWITCH DEVICE FOR CONTROLLING THE CLOSURE OF FOLDING DOORS
(FR) DISPOSITIF INTERRUPTEUR POUR LE CONTROLE DE LA FERMETURE D"UNE PORTE A BATTANT
Abstract:
(EN) It is necessary for the doors of prison cells, of sales, as well as the doors of armoured boxes and cupboards, to protect the switch which is mounted on the door or on the frame and which, by the closing motion of the door, releases a signal, against the manipulation by non authorized people, for example releasing of false signal by a prisoner when the door of the cell remains open. For this purpose, a signal switch (3) with contact roller (16) is fixed to the door (1), a fixed eccentric disc (4) working as the actuator of the switch being removably attached to the frame (2). This mechanical switch device (3, 4, 16) is arranged into a box (5) of which the base (6) is welded to the door (1) and the dome-shaped cap (7) is locked from the inside to the base (6) of the box by means of a cylinder lock (8) arranged in the box, for preventing the removal thereof. In the case of an optical device, an infra-red ray transmitter (35) and a ray receiver (36) with an interrupter transistor (49) are arranged inside the door, respectively the frame, or vice versa. The infra-red beam (41) is transmitted to the receiver (36) through two openings (39, 40), of the door (1) and of the frame (2), which are in alignment only when the door is in a closed position, causing the release of a signal.
(FR) Il est necessaire pour les portes de cellules de prisons, les portes de coffres-forts ainsi que les portes de caisses et d"armoires blindees de proteger l"interrupteur qui est fixe sur la porte ou sur le cadre et qui par le mouvement de fermeture de la porte declenche un signal, contre les manipulations par des personnes non autorisees, par exemple le declenchement d"un faux signal par un detenu lorsque la porte de la cellule reste ouverte. A cet effet, un interrupteur de signal (3) avec roulette de contact (16) est fixe a la porte (1), un disque excentrique fixe (4) servant d"organe d"actionnement de l"interrupteur est fixe de maniere detachable a son cadre (2). Ce dispositif interrupteur mecanique (3, 4, 16) est place dans un boitier (5) dont la base (6) est soudee a la porte (1) et dont le couvercle en forme de calotte (7) est verrouille de l"interieur avec la base (6) du boitier au moyen d"une serrure a cylindre (8) placee dans le boitier, ce qui l"assure contre l"enlevement. Dans le cas d"un dispositif optique, un emetteur (35) a rayons infrarouges et un recepteur de rayons (36) avec un transistor d"interruption (49) sont disposes a l"interieur de la porte, respectivement du cadre, ou l"inverse. Le faisceau de rayons infrarouges (41) est transmis au recepteur (36) a travers deux ouvertures (39, 40) de la porte (1) et du cadre (2) qui sont alignees seulement en position de fermeture de la porte (1), ce qui declenche un signal.
