Abstract

The lock consists of a solid falling latch (6) fixed to the operating shaft (5), which in turn is carried by a plate (4), forming the fixed base of the lock. This base plate is secured to the hinged door (2) of the cabinet and has a projecting sheath (4a) which passes into the internal boss (2a), which projects inwards from the door. The sheath surrounds and supports the operating shaft. The end of the sheath is formed into an annular ridge (4b) which engages with a mating projection (8b) formed on one of the ends of the tubular locking accessory (8), which is held in place by an elastic clipping of the two ridges. The specialised operating key (7) passes into the accessory tube to engage in the end of the operating shaft to enable the latch to be raised.

Description

La présente invention a trait aux coffrets et arMoires techniques qui sont généralement placés le long des voies publiques pour renfermer les appareillages de branchement, de protection et de comptage destines à l'alimentation des locaux en eau, gaz, électricité et téléphone. The present invention relates to boxes and technical cabinets which are generally placed along public roads to contain the connection, protection and metering equipment intended for supplying premises with water, gas, electricity and telephone.

Lorsque les appareillages logés dans ce type de coffrets ne présentent pas une très grande valeur ou un caractère très dangereux (cas des compteurs, détendeurs, vannes, fusibles, etc...), on se contente en pratique d'assurer la fermeture de la porte d'accès à L'aide d'une serrure manoeuvrée à l'aide d'une clef spéciale dont l'utilisation est limitée au personnel qualifié de maintenance. Par contre, quand on a affaire à des appareillages plus sophistiqués ou comportant des risques accentués, on a recours à des serrures dotées d'une condamnation interdisant catégoriquement tout accès à un personneL non strictement qualifié. When the equipment housed in this type of boxes does not have a very high value or a very dangerous character (in the case of meters, regulators, valves, fuses, etc.), we are content in practice to ensure the closing of the Access door using a lock operated with a special key, the use of which is limited to qualified maintenance personnel. On the other hand, when we are dealing with more sophisticated equipment or with increased risks, we use locks with a conviction categorically prohibiting any access to a person not strictly qualified.

Les Services Publics doivent donc disposer de deux types de coffrets (å clef spéciale et à condamnation), ce qui augmente sensibLement
Les coûts de fabrication et de stockage. Par aiLleurs et surtout, iL est relativement fréquent qu'un coffret ou armoire technique qui à l'origine se contentait d'une serrure à clef spéciaLe soit appeLé à recevoir un nouvel appareillage impliquant le recours obligatoire à une serrure à condamnation, auquel cas il y a lieu de procéder au démontage des appatreillages renfermés, au remplacement du coffret et au remontage de L'en senble des appareillages, toutes ces opérations nécessitant de faire appel à un personnel hautement qualifié.
Public Services must therefore have two types of boxes (special key and lockable), which significantly increases
Manufacturing and storage costs. By the way, and above all, it is relatively frequent that a technical box or cupboard which originally contented itself with a special key lock is called to receive a new device implying the compulsory use of a locking lock, in which case it there is a need to disassemble the enclosed equipment, replace the box and reassemble the assembly of equipment, all these operations requiring the use of highly qualified personnel.

C'est à ces inconvénients qu'entend principalement renedier la présente invention, laquelle a pour objet une serrure du type à clef spéciale qui est susceptible d'être instantanément dotée d'un accessoire de condamnation indémontable, sans impliquer L'intervention d'un personnel qualifié et sans même qu'il soit nécessaire d'avoir acces à l'intérieur du coffret ou armoire auquel ladite serrure est fixée. It is to these drawbacks that the present invention mainly intends to renounce, which has as its object a lock of the special key type which is capable of being instantly provided with a non-removable locking accessory, without involving the intervention of a qualified personnel and without it even being necessary to have access inside the box or cupboard to which said lock is fixed.

L'invention consiste essentiellement à faire comporter à La platine usuelle qui porte l'arbre pour la manoeuvre du Loquet, un fourreau cylindrique qui entoure ledit arbre et qui présente en bout une nervure annulaire apte à coopérer avec une saillie conjuguée prévue à L'une des extrémités d'un accessoire tubulaire de condamnation qui est ainsi retenu par encliquetage élastique. The invention consists essentially in having the usual plate which carries the shaft for the operation of the latch, a cylindrical sheath which surrounds said shaft and which has at the end an annular rib capable of cooperating with a conjugate projection provided in the one ends of a tubular locking accessory which is thus retained by elastic snap-fastening.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre L'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :
Fig. 1 est une coupe axiale schématique d'une serrure établie conformément à la présente invention.
The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:
Fig. 1 is a schematic axial section of a lock established in accordance with the present invention.

Fig. 2 est une vue en perspective illustrant la mise en place et la solidarisation d'un accessoire de condamnation. Fig. 2 is a perspective view illustrating the installation and securing of a locking accessory.

Fig. 3 et 4 sont des vues analogues à celles suivant fig. 1 et 2, mais montrant un autre type d'accessoire de condamnation. Fig. 3 and 4 are views similar to those according to FIG. 1 and 2, but showing another type of locking accessory.

En fig. 1, la référence 1 désigne la partie antérieure ouverte d'un coffret technique équipé d'une porte articulée 2 dont le bord Libre vient porter contre une feuillure intérieure la. Cette porte 2 presente un bossage interne surépaissi 2a contre la face arriére duquel vient se fixer, à L'aide de vis telles que 3, une platine 4 constituant en fait le bâti fixe de la serrure. Cette dernière comprend, à La façon usueLLe, un arbre 5 dont une extrémité est munie d'un loquet 6 destiné par rotation à prendre appui contre la face arrière de la feuillure la, tandis que l'extrémité opposée, tournée vers l'extérieur, est profilée en 5a pour permettre la manoeuvre angulaire de l'arbre à L'aide d'une clef spéciale 7. In fig. 1, the reference 1 designates the open front part of a technical box fitted with an articulated door 2, the free edge of which comes to bear against an internal rebate 1a. This door 2 has a thickened internal boss 2a against the rear face of which is fixed, using screws such as 3, a plate 4 constituting in fact the fixed frame of the lock. The latter comprises, in the usual way, a shaft 5, one end of which is provided with a latch 6 intended by rotation to bear against the rear face of the rebate 1a, while the opposite end, facing outwards, is profiled at 5a to allow angular maneuvering of the shaft using a special key 7.

Conformément à l'invention, on a fait comporter à la platine 4 un fourreau cylindrique 4a qui est engagé dans l'ouverture 2b pratiquée dans le bossage 2a pour le passage de l'arbre 5, lequel fourreau forme ainsi guide ou palier pour ledit arbre. L'extrémité libre de ce fourreau 4a, disposée à l'intérieur de l'ouverture 2b précitée, présente une nervure annulaire 4b tournée vers l'extérieur. According to the invention, the plate 4 has had a cylindrical sheath 4a which is engaged in the opening 2b made in the boss 2a for the passage of the shaft 5, which sheath thus forms guide or bearing for said shaft . The free end of this sheath 4a, disposed inside the abovementioned opening 2b, has an annular rib 4b facing outwards.

Une telle serrure à loquet basculant fonctionne identiquement de la même manière que les serrures usuelles de ce genre, à savoir que le personnet qualifié qui dispose d'une clef telLe que 7 peut manoeuvrer angulairement L'arbre 5 pour faire passer le loquet de la position ouverte à la position fermée et vice versa. Such a tilting latch lock operates identically in the same way as usual locks of this kind, namely that the qualified person who has a key such as 7 can angularly operate the shaft 5 to move the latch from the position. open to the closed position and vice versa.

On a par aiLleurs réalisé des accessoires de condamnation agences de manière à venir se fixer par encliquetage ou clipsage élastique contre la serrure. En fig. 1 et 2, il s'agit d'un accessoire destiné à la pose d'un cadenas, de sorte qu'il comprend un manchon cylindrique 8 dont La paroi est percée de deux lumières opposées 8a pour L'engagement de La tige 9a du cadenas 9, laquelle tige vient se disposer transversa liement à L'arbre 5 en interdisant l'introduction de la cLef 7. We have also made accessories for locking agencies so as to be fixed by snap-fastening or elastic clipping against the lock. In fig. 1 and 2, it is an accessory intended for the installation of a padlock, so that it comprises a cylindrical sleeve 8 the wall of which is pierced with two opposite slots 8a for the engagement of the rod 9a of the padlock 9, which rod is arranged transversely to the shaft 5 by prohibiting the introduction of the cLef 7.

Dans Le cas de fig. 3 et 4, l'accessoire de condamnation est destiné à la pose d'un plomb de garantie, si bien qu'il prend la forme d'un boitier cylindrique 10 qui se prolonge pour constituer une sorte de petit étui 10a qui est fermé par un portillon 10b et qui renferme un oeillet 10c, ce dernier étant destiné à coopérer avec un oeillet équivalent 5b prévu en bout de L'arbre 5 pour permettre la pose d'un fil associé à un plomb de garantie. In the case of fig. 3 and 4, the locking accessory is intended for the installation of a guarantee plummet, so that it takes the form of a cylindrical case 10 which is extended to constitute a sort of small case 10a which is closed by a gate 10b and which contains an eyelet 10c, the latter being intended to cooperate with an equivalent eyelet 5b provided at the end of the shaft 5 to allow the installation of a wire associated with a lead seal.

Dans le premier cas (fig. 1 et 2), l'extrémité arrière du manchon 8 est pourvue d'une saillie annulaire 8b tournée vers l'intérieur. De la même manière, L'extrémité arrière du boîtier 10 présente une saillie annulaire identique 10d (fig. 3 et 4).On conçoit que si le débouché élargi Zc de l'ouverture 2h du bossage 2a est établi à un diamètre intérieur approprié, la partie arrière du manchon 8 ou du boitier 10 est susceptible d'être engagée axialement autour de la partie profilée Sa de l'arbre 5 et d'être ainsi étroitement guidée jusqu'à ce que, moyennant un léger effort de L'opérateur, la saillie 8b, respectivement 10d, se déforme élastiquement pour passer par dessus la nervure 4b du fourreau 4 et se clipser en place. L'accessoire de condamnation est alors fixé définitivement au fourreau 4 de la serrure et ne peut se désolidariser de celui-ci. In the first case (fig. 1 and 2), the rear end of the sleeve 8 is provided with an annular projection 8b facing inward. In the same way, the rear end of the housing 10 has an identical annular projection 10d (FIGS. 3 and 4). It is conceivable that if the enlarged outlet Zc of the opening 2h of the boss 2a is established at an appropriate internal diameter, the rear part of the sleeve 8 or of the housing 10 is capable of being engaged axially around the profiled part Sa of the shaft 5 and of being thus closely guided until, with a slight effort from the operator, the projection 8b, respectively 10d, elastically deforms to pass over the rib 4b of the sheath 4 and clip in place. The locking accessory is then permanently fixed to the sheath 4 of the lock and cannot be detached from the latter.

On notera que cette fixation, effectuée par l'avant, ne nécessite aucun outil et est opérée sans qu'il soit même nécessaire d'ouvrir la porte 2.  It will be noted that this fixing, carried out from the front, requires no tools and is operated without it even being necessary to open the door 2.

Il va de soi qu'on peut imaginer d'autres formes de réalisation pour les accessoires de condamnation, pour autant que le corps de ceux -ci comporte une partie cylindrique pourvue en bout d'une saillie annulaire d'encliquetage. It goes without saying that other embodiments can be imagined for the locking accessories, provided that the body of these comprises a cylindrical part provided at the end with an annular latching projection.

Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elLe ne limite nullement le domaine de L'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents.  It should also be understood that the foregoing description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
