Abstract

The device, which is the subject of the invention, is inserted between the plug F of the appliance U to be protected and the mains power socket. The plug F is held captive in a casing 1, the cover 2 closing by turning a key 3. This rotation simultaneously actuates a switch 5 which, in series in the electrical circuit, cuts the supply to the appliance U. On removing the key, the appliance cannot be used. A turn of the key, on the contrary, re-establishes the current and the use of the appliance. It is thus also possible to remove the device. Among the most interesting applications of the invention, mention may be made of the limitation of the use of electrical appliances for safety, cost-saving and regulatory reasons, both in an industrial environment and in community situations or for domestic applications, machine tools, electronic devices (televisions, Minitels (video-text information systems), computers).

Description

La présente. invention concerne un dispositif interrupteur électrique à clé, adptable à tout appareil électrique, dont on veut maîtriser l'usage. The current. The invention relates to an electrical key switch device, suitable for any electrical device, the use of which is to be controlled.

A ce jour, pour limiter ou contrôler l'usage d'un appareil électrique, il faut : le débrancher, le transporter et le mettre sous clés, ou le faire modifier en lui greffant un système particulier de protection. To date, to limit or control the use of an electrical appliance, you must: unplug it, transport it and lock it, or have it modified by adding a special protection system.

Le dispositif selon l'invention permet, sans outillage et sans modification, de l'adapter, en l'intercallant entre la fiche de l'appareil a pro téger et la prise du réseau de distribution d'électricité. The device according to the invention makes it possible, without tools and without modification, to adapt it, by interposing it between the plug of the device to be protected and the socket of the electricity distribution network.

Le dispositif est composé d'un boitier a couvercle muni d'une serrure à clé. Dans le boitier une prise reçoit la fiche de l'appareil à protéger. The device consists of a cover box fitted with a key lock. In the case a socket receives the plug of the device to be protected.

En fermant le couvercle et en actionnant la clé, l'usagé condamne l'accès intérieur du boitier et dans son mouvement de rotation le penne actionne, simultanément, un interrupteur. Ce dernier coupe l'arrivée du courant, à la prise intérieure du boitier, venant par un cordon de l'extérieur et prolonge d'une fiche branché sur le réseau. L'appareil à protéger se trouve, dans ces conditions, privé d'électricité. Par un nouveau tour de clé, l'interrupteur libère la passage du courant qui alimente l'appareil à protéger. Le couvercle simultanément libéré permet, dans cette position seulement, d'ouvrir, de débrancher et d'enlever le dispositif, objet de l'invention, si nécessaire.By closing the cover and activating the key, the user blocks the interior access to the box and, in its rotational movement, the pin activates, simultaneously, a switch. The latter cuts off the supply of current to the inside socket of the box, coming from a cord from the outside and extends from a plug connected to the network. The device to be protected is, in these conditions, deprived of electricity. By a new turn of the key, the switch frees the passage of current which supplies the device to be protected. The simultaneously released cover allows, in this position only, to open, disconnect and remove the device, object of the invention, if necessary.

Selon une première variante, sous l'action dtun tour de clé le penne condamne ou libère l'ouverture du couvercle. Simultanément un volet solidaire du penne occulte ou libère une ouverture dans le couvercle donnant accés, à l'aide d'un doigt, à la manoeuvre de l'interrupteur. Cette variante permet de différencier les deux actions : libération du couvercle, action possible sur l'interrupteur. According to a first variant, under the action of a turn of the key, the pin locks or releases the opening of the cover. Simultaneously a shutter secured to the blind pin or releases an opening in the cover giving access, using a finger, to the operation of the switch. This variant makes it possible to differentiate the two actions: release of the cover, possible action on the switch.

Selon un deuxième variante, un tour de clé libère le couvercle qui sous l'action d'un ressort se soulève, libère l'interrupteur à poussoir t rétablit le passage des courants. According to a second variant, a turn of the key releases the cover which, under the action of a spring, lifts, releases the push-button switch t restores the passage of currents.

L'ordre de grandeur du dispositif est d'environ 150 x 100 x 50 millimètres. Tel qu'il est représenté, figure 1, 2, 3, le dispositif comporte un boitier (I) à porte (2) muni d'une fermeture à clé (3) une prise (4) reçoit la fiche (F) de l'appareil électrique (U) à utiliser. Son cordon d'alimentation passe par une encoche (8) du boitier. Le dispositif étant en place tel qu'il est représenté figure 1 et 2, un demi tour de clé déverrouille le couvercle et le penne, en fin de rotation, fait pression sur l'interrupteur (5) le courant passe et alimente la prise (4) et par delà, l'utilisation (U). Dans cette position l'accés à la fiche (F) est libre et permet d'enlever lé dispositif ou de le mettre en place lors du premier usage.A l'inverse un demi tour de clé (3) libère la pression du penne sur l'interrupteur (5) qui coupe l'alimentation de l'appareil (U) branché sur le dispositif. En fin de course le penne verrouille le couvercle sur la boite interdisant l'accés à la fiche (F). L'appareil (U) est condamné. Dans la forme de réalisation de la figure (F), un trou rond, suffisant pour le passage d'un doigt, laisse l'acces à la manoeuvre de l'interrupteur (5). The order of magnitude of the device is approximately 150 x 100 x 50 millimeters. As shown, Figure 1, 2, 3, the device comprises a box (I) with door (2) provided with a key lock (3) a socket (4) receives the plug (F) from the electrical appliance (U) to be used. Its power cord goes through a notch (8) in the box. The device being in place as shown in FIGS. 1 and 2, a half turn of the key unlocks the cover and the pin, at the end of rotation, presses the switch (5) the current flows and feeds the socket ( 4) and beyond, the use (U). In this position the access to the plug (F) is free and allows to remove the device or to put it in place during the first use. Conversely a half turn of the key (3) releases the pressure of the pin on the switch (5) which cuts the power to the device (U) connected to the device. At the end of the stroke, the pin locks the cover on the box preventing access to the plug (F). The device (U) is locked. In the embodiment of Figure (F), a round hole, sufficient for the passage of a finger, gives access to the operation of the switch (5).

Un volet solidaire de la rotation du penne obture l'ouverture et simultanément, le penne, verrouille l'accés au boitier. Les fonctions d'ouverture/fermeture et arrêt/marche sont dissociées.A shutter integral with the rotation of the pin closes the opening and simultaneously, the pin, locks access to the housing. The open / close and stop / start functions are separated.

Dans la forme de réalisation de la figure 5 le couvercle (2), dans sa position fermée, fait pression sur l'interrupteur à poussoir (5) le circuit est coupé, l'appareil (4) est inutilisable. Dans la position déverrouillée le ressort repousse le couvercle, libère le poussoir (5) qui rétablit le passege du courant. L'appareil (U) est utilisable. In the embodiment of FIG. 5, the cover (2), in its closed position, presses the push-button switch (5), the circuit is cut, the device (4) cannot be used. In the unlocked position the spring pushes the cover back, releases the pusher (5) which restores the current flow. The device (U) can be used.

Dans le cas ou l'interrupteur (5) est à état permanent, et suivant son état initial, la fonction de la 1ère et 2ème variante du dispositif sera inverséeet pourra interdire de couper l'alimentation de l'appareil à utiliser. In the case where the switch (5) is in a permanent state, and according to its initial state, the function of the 1st and 2nd variant of the device will be reversed and may prohibit cutting the power supply to the device to be used.

L'invention permet, en milieu industriel et aux collectivités, de contrôler l'usage d'appareils à protéger pour des raisons de sécurités de personnes et de machines, d'économie, de règlements. The invention makes it possible, in an industrial environment and in communities, to control the use of devices to be protected for reasons of safety of people and machines, economy, regulations.
