Description
SERRURE POUR PASSAGES POMPIERS
La présente invention a pour objet une serrure pour passages pompiers.LOCK FOR FIREFIGHTS
The present invention relates to a lock for fire passages.
Elle est destinée en particulier à équiper les portes de clôtures entourant les propriétés de campagne, privées ou non, ou les passages pour services publics. It is intended in particular to equip the doors with fences surrounding country properties, private or not, or passages for public services.
Lors de leurs interventions, par exemple en cas d'incendie de forêt, les pompiers doivent pouvoir franchir sans perdre de temps les enceintes défendant les diverses propriétés qu'ils sont amenés à traverser. Dans ce but, les fermetures de ces enceintes sont obligatoirement équipées de serrures pouvant être manoeuvrées par une clé d'un modèle bien d-terming que toutes les équipes de pompiers peuvent avoir à leur disposition
Cependant ces serrures, en général très rustiques, présentent plusieurs inconvénients:
- Elles sont très souvent faciles à ouvrir à l'aide d'une s 7 mple-pince. During their interventions, for example in the event of a forest fire, the firefighters must be able to cross without losing time the enclosures defending the various properties that they are brought to cross. For this purpose, the closings of these enclosures are necessarily equipped with locks that can be operated by a key of a well-defined model that all fire teams can have at their disposal.
However, these locks, generally very rustic, have several disadvantages:
- They are very often easy to open using a 7 mple pliers.
- Dans le feu de l'action, il arrive fréquemment que la personne ayant ouvert le vantail ne se donne pas la peine de le refermer, en particulier quand un convoi important doit passer. Cela peut entraîner des problèmes gênants pour le propriétaire, tels que perte de bétail ou visites non désirées. - In the heat of the moment, it often happens that the person who opened the leaf does not bother to close it, especially when an important convoy has to pass. This can lead to troublesome problems for the owner, such as loss of livestock or unwanted visits.
Le dispositif selon la présente invention supprime ces inconvenienis. En effet, il permet d'obtenir une serrure particulièrement robuste, impossible à manoeuvrer avec une pince si elle a été correctement fermée, et dans laquelle la clé est emprisonnée tans que la porte qu'elle équipe n'est pas refermée. The device according to the present invention eliminates these inconvenienis. In fact, it makes it possible to obtain a particularly robust lock, impossible to operate with pliers if it has been correctly closed, and in which the key is trapped while the door which it equips is not closed.
Il est constitué par la combinaison d'un étrier sur un des côtés duquel est fixé un tube comportant un écrou interne solidaire dans lequel est vissée une tige filetée manoeuvrable par une clé pénétrant dans ledit tube, prolongée du côté de l'étrier par un pène cylindrique traversant une paroi de celui-ci, des griffes actionnées par la tige filetée emprisonnant la clé tant que la serrure n'est pas verrouillée, un piston non actionnable à la main étant maintenu par un ressort devant le pêne pour empêcher le verrouillage lorsque le passage n'est pas referme. It is constituted by the combination of a stirrup on one side of which is fixed a tube comprising an integral internal nut into which is screwed a threaded rod operable by a key penetrating into said tube, extended on the side of the stirrup by a bolt cylindrical through a wall thereof, claws actuated by the threaded rod trapping the key as long as the lock is not locked, a piston not actuable by hand being held by a spring in front of the bolt to prevent locking when the passage is not closed.
Sur les dessins annexés, donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention:
la figure 1 est une coupe longitudinale horizontale, suivant les flèches B-B de la figure 3, du dispositif dans son ensemble en position déverrouillée, avec la clé de manoeuvre emprisonnée,
la figure 2 représente dans les mêmes conditions le dispositif en position verrouillée,
et la figure 3 est une coupe transversale suivant les flèches A-A de la figure 1.In the accompanying drawings, given by way of nonlimiting example of one of the embodiments of the subject of the invention:
FIG. 1 is a horizontal longitudinal section, along the arrows BB of FIG. 3, of the device as a whole in the unlocked position, with the operating key trapped,
FIG. 2 shows, under the same conditions, the device in the locked position,
and FIG. 3 is a cross section along the arrows AA of FIG. 1.
Le dispositif, figures 1 à 3, est constitué d'un étrier 1 en tôle pliée de forte épaisseur, sur un des côtés duquel est soudé un tube 2 métallique de section circulaire ou polygonale comportant un écrou 4 interne solidaire dans lequel est vissée une tige filetée 3, le tube, la tige filetée et l'écrou étant coaxiaux. The device, FIGS. 1 to 3, consists of a stirrup 1 made of very thick folded sheet metal, on one side of which is welded a metal tube 2 of circular or polygonal section comprising an integral internal nut 4 into which a rod is screwed threaded 3, the tube, the threaded rod and the nut being coaxial.
Ladite tige filetée est prolongée #u côté de l'étrier 1 par une tige cylindrique 5 pouvant s'engager dans un trou prévu dans la paroi de l'étrier et, de l'autre côté, d'une tête prismatique 6 permettant d'actionner la tige filetée 3 au moyen d'une clé 8 comportant une empreinte correspondant au dit élément prismatique Cette clé est d'un modèle connu pouvant être introduite à l'intérieur du tube 2 et formée d'une poignée de manoeuvre et du porte-empreinte cylindrique, reliés par une partie centrale de diamètre réduit, la partie porteempreinte comportant de ce fait un épaulement. Said threaded rod is extended on the side of the stirrup 1 by a cylindrical rod 5 which can engage in a hole provided in the wall of the stirrup and, on the other side, with a prismatic head 6 making it possible to actuate the threaded rod 3 by means of a key 8 comprising an imprint corresponding to said prismatic element This key is of a known model which can be introduced inside the tube 2 and formed of an operating handle and of the holder cylindrical cavity, connected by a central part of reduced diameter, the cavity part therefore comprising a shoulder.
L'étrier 1 peut être monté aussi bien sur le vantail ou sur la partie fixe de l'ouverture a equiper que sur une chaîne ou un câble, l'autre partie comportant un élément plat 7 enserré par l'étrier lors de la fermeture. The bracket 1 can be mounted both on the leaf or on the fixed part of the opening to be fitted as on a chain or a cable, the other part comprising a flat element 7 enclosed by the bracket during closing.
La tige cylindrique 5 joue le rôle de pène et vient se loger dans un trou dudit élément plat en position verrouillée.The cylindrical rod 5 acts as a bolt and is housed in a hole in said flat element in the locked position.
A L'intérieur du tube 2 se trouvent au moins une griffe 10 en acier flexible, coulissant dans un ou des évidements prévus à cet effet dans l'écrou 4 et comportant une partie pliée s 'insérant entre l'extrémité de la tige filetée 3 et une rondelle 9 soudée sur la tige cylindrique 5 de manière à ce que la ou les dites griffes soient entraînées par les deplacements longitudinaux de la tige filetée. L'extrémité opposée des griffe est pourvue d'un retour formant ergot et se déplace sur des rampes inclinées li fixées à l'intérieur du tube 2 et disposées de telle manière que, lorsque la tige filetée est dévissée au moyen de la clé 8; ledit retour se rapproche de l'axe du tube et passe derrière l'épaulement de ladite clé en empêchant ainsi cette dernière de sortir du tube. 2. Inside the tube 2 are at least one claw 10 of flexible steel, sliding in one or more recesses provided for this purpose in the nut 4 and comprising a folded part s' inserted between the end of the threaded rod 3 and a washer 9 welded to the cylindrical rod 5 so that the said claw or claws are driven by the longitudinal displacements of the threaded rod. The opposite end of the claws is provided with a lug-shaped return and moves on inclined ramps li fixed inside the tube 2 and arranged in such a way that, when the threaded rod is unscrewed by means of the key 8; said return approaches the axis of the tube and passes behind the shoulder of said key thereby preventing the latter from leaving the tube. 2.
Pour éviter que la clé 8 puisse être retirée, une fois le vantail ouvert, en revissant la tige filetée 3, l'étrier 1 est équipé d'un-piston 12 qutun ressort 13 pousse devant la tige cylindrique 5 dès que l'élément plat 7 est séparé de l'étrier 1. Ce ressort, logé dans un capot 14 fixé sur l'étrier, est suffisamment puissant pour que le piston 12 ne puisse pas être actionné manuellement, mais seulement par la fermuture du vantail. To prevent the key 8 from being able to be removed, once the leaf has been opened, by screwing the threaded rod 3 back, the caliper 1 is fitted with a piston 12 that a spring 13 pushes in front of the cylindrical rod 5 as soon as the flat element 7 is separated from the caliper 1. This spring, housed in a cover 14 fixed on the caliper, is powerful enough that the piston 12 cannot be actuated manually, but only by closing the leaf.
La conception du dispositif décrit ci-dessus présente un avantage supplémentaire par rapport aux serrures similaires généralement de type quart-de-tcur ou demi-tour. En effet, l'utilisation d'un pène actionne au moyen d'une tige filetée permet en serrant très fortement cette dernière de rendre pratiquement impossible le déverrouillage au moyen d'une pince. The design of the device described above has an additional advantage compared to similar locks generally of the quarter-turn or half-turn type. Indeed, the use of a bolt actuated by means of a threaded rod makes it possible by tightening it very tightly to make it practically impossible to unlock by means of a clamp.
Le positionnement des divers éléments constitutifs donne a l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires. The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
