Description

DISPOSITIF DE FIXATION INVISIBLE D'UNE PLATINE SUR UNE
PLAQUE D'APPLIQUE.DEVICE FOR INVISIBLE FIXING OF A PLATE ON A
WALL PLATE.

La présente invention concerne un dispositif de fixation d'une platine sur une surface, et plus particulièrement une platine portant un dispositif de signalisation et qui doit être appliquée à l'intérieur d'une cabine d'ascenseur ou sur le palier. The present invention relates to a device for fixing a plate on a surface, and more particularly a plate carrying a signaling device and which must be applied inside an elevator car or on the landing.

Jusqu'à présent, les platines de ce type étaient fixées au moyen de vis ou analogues, visibles de l'extérieur, de sorte qu'elles pouvaient être facilement démontées par n'importe qui. Until now, plates of this type have been fixed by means of screws or the like, visible from the outside, so that they could be easily disassembled by anyone.

La présente invention vise à remédier à cet inconvénient en proposant un système de fixation pour platine sur une plaque d'applique, qui soit invisible de l'extérieur et qui soit pourvu d'un verrouillage de sécurité s'opposant au démontage intempestif de la platine. The present invention aims to remedy this drawback by proposing a fixing system for a plate on a wall plate, which is invisible from the outside and which is provided with a safety lock opposing the untimely disassembly of the plate. .

Le dispositif de fixation selon l'invention se caractérise en ce qu'il comprend
- au moins une tige fixée sur une face ou face arrière de la platine, perpendiculairement à celle-ci,
- une rondelle montée coulissante librement sur la tige et pourvue d'un bord extérieur chanfreiné tourné vers la platine,
- un ressort prenant appui contre une bague solidaire de la tige et sollicitant la rondelle contre ladite face arrière de la platine,
- au moins un trou percé sur la plaque d'applique pour le passage de la tige et de la rondelle, ledit trou comprenant un premier orifice sensiblement circulaire de diamètre légèrement supérieur au diamètre extérieur de la rondelle et un second orifice circulaire sécant avec le premier et ayant un diamètre compris entre celui de la tige et le diamètre extérieur de la rondelle,
- et un taquet formé sur la face arrière de la platine, légèrement au-dessus de la tige, la platine pouvant être glissée d'une première position où la tige est engagée dans le premier orifice, à une seconde position où elle est reçue dans le second orifice, la rondelle étant alors repoussée par la plaque d'applique à l'encontre de la force du ressort associé, et où le taquet s'encliquette dans ledit premier orifice.The fixing device according to the invention is characterized in that it comprises
- at least one rod fixed to a face or rear face of the plate, perpendicular to the latter,
- a washer mounted to slide freely on the rod and provided with a chamfered outer edge facing the plate,
a spring bearing against a ring integral with the rod and urging the washer against said rear face of the plate,
- At least one hole drilled on the wall plate for the passage of the rod and the washer, said hole comprising a first substantially circular orifice with a diameter slightly greater than the outside diameter of the washer and a second circular orifice intersecting with the first and having a diameter between that of the rod and the outside diameter of the washer,
- And a cleat formed on the rear face of the plate, slightly above the rod, the plate being able to be slid from a first position where the rod is engaged in the first orifice, to a second position where it is received in the second orifice, the washer then being pushed back by the wall plate against the force of the associated spring, and where the cleat snaps into said first orifice.

Dans ladite seconde position, la platine ne peut pas être démontée accidentellement puisque la rondelle s'oppose à son retrait dans le sens perpendiculaire à la plaque d'applique et que le taquet empêche de faire glisser la platine dans le sens de son dégagement. In said second position, the plate cannot be dismantled accidentally since the washer opposes its removal in the direction perpendicular to the wall plate and the cleat prevents the plate from sliding in the direction of its release.

La platine peut être munie de plusieurs systèmes de fixation analogues à celui qui vient d'être décrit. Par exemple, une platine rectangulaire peut comporter deux ou plusieurs systèmes de fixation situés respectivement près de ses bords supérieur et inférieur. The plate can be provided with several fixing systems similar to that which has just been described. For example, a rectangular plate may have two or more fixing systems located respectively near its upper and lower edges.

Un mode de réalisation de l'invention sera décrit à présent en regard du dessin annexé dans lequel

Sur la figure 1, on a représenté une platine 10 portant sur sa face arrière un équipement quelconque 12 que l'on se propose de fixer en applique, par exemple sur une tôle 14, à l'intérieur d'une cabine d'ascenseur ou sur le palier. La tôle présente une ouverture 16 pour le logement de l'équipement 12. In FIG. 1, there is shown a plate 10 carrying on its rear face any piece of equipment 12 which it is proposed to attach to the surface, for example on a sheet metal 14, inside an elevator car or on the landing. The sheet has an opening 16 for housing the equipment 12.

Pour sa fixation, la platine est munie sur sa face arrière de deux dispositifs de fixation 18, 18' identiques, mais comme on l'a signalé précédemment, elle pourrait en avoir un ou plus de deux, selon sa forme et ses dimensions. For its fixing, the plate is provided on its rear face with two identical fixing devices 18, 18 ′, but as previously indicated, it could have one or more than two, depending on its shape and dimensions.

Comme le montre clairement la figure 3, chacun des dispositifs de fixation comprend une tige 20 soudée sur la face arrière de la platine, perpendiculairement à celleci. Sur la tige est montée coulissante librement une rondelle 22 qui présente un chanfrein 24 sur son bord externe tourné vers la platine. La rondelle est normalement sollicitée contre la platine par un ressort 26 dont l'autre extrémité prend appui contre une bague 28, elle-même en butée contre un circlip 30. As clearly shown in Figure 3, each of the fastening devices comprises a rod 20 welded to the rear face of the plate, perpendicular thereto. On the rod is slidably mounted a washer 22 which has a chamfer 24 on its outer edge facing the plate. The washer is normally biased against the plate by a spring 26, the other end of which bears against a ring 28, itself in abutment against a circlip 30.

Sur la tôle 14 sont percés des trous 32, 32' destinés à recevoir respectivement les dispositifs de fixation 18, 18'. Comme le montre la figure 2, chacun de ces trous est formé de deux orifices sécants 34, 36 dont la ligne des centres est orientée verticalement. L'orifice supérieur 34 de chaque trou a un diamètre D1 légèrement supérieur au diamètre extérieur de la rondelle 22, tandis que l'orifice inférieur 36 a un diamètre D2 compris entre celui de la tige 20 et celui de la rondelle. La zone d'étranglement située au passage entre les orifices 34 et 36 a une largeur légèrement supérieure au diamètre de la tige 20. On the sheet 14 are drilled holes 32, 32 'intended to receive the fastening devices 18, 18' respectively. As shown in Figure 2, each of these holes is formed of two intersecting orifices 34, 36 whose line of centers is oriented vertically. The upper hole 34 of each hole has a diameter D1 slightly greater than the outside diameter of the washer 22, while the lower hole 36 has a diameter D2 between that of the rod 20 and that of the washer. The throttling zone situated at the passage between the orifices 34 and 36 has a width slightly greater than the diameter of the rod 20.

La platine 10 est munie sur sa face arrière, au-dessus du dispositif de fixation supérieur 18, d'un taquet 38 dont le rôle sera expliqué par la suite. The plate 10 is provided on its rear face, above the upper fastening device 18, with a cleat 38 whose role will be explained later.

Dans ces conditions, le montage de la platine s'effectue comme suit : tout d'abord, on applique la platine 10 sur la tôle 14 en prenant soin d'engager l'équipement 12 dans l'ouverture 16 et les dispositifs de fixation 18, 18' respectivement dans les orifices de grand diamètre 34 des trous 32, 32'. La platine 10 est alors dans la position montrée sur la figure 4. On notera que la partie supérieure de la platine est maintenue écartée de la tôle 12 avec un faible jeu e, par le taquet 38 qui est en appui contre la tôle. Under these conditions, the mounting of the plate is carried out as follows: firstly, the plate 10 is applied to the sheet 14, taking care to engage the equipment 12 in the opening 16 and the fixing devices 18 , 18 'respectively in the large diameter orifices 34 of the holes 32, 32'. The plate 10 is then in the position shown in FIG. 4. It will be noted that the upper part of the plate is kept apart from the sheet 12 with a small clearance e, by the cleat 38 which is in abutment against the sheet.

La figure 5 montre la position relative de la rondelle 22 et de la tige 20 dans l'orifice 34. FIG. 5 shows the relative position of the washer 22 and of the rod 20 in the orifice 34.

Dans un second temps, on fait descendre la platine dans le sens de la flèche f sur la figure 4. Dans ce mouvement, le bord de l'orifice 34 s'engage derrière le chanfrein 24 et repousse la rondelle 22 à l'encontre du ressort 26. Le taquet 38 est toujours en appui contre la tôle 12. Cette position est illustrée par les figures 6 et 7. In a second step, the plate is lowered in the direction of the arrow f in FIG. 4. In this movement, the edge of the orifice 34 engages behind the chamfer 24 and pushes the washer 22 against the spring 26. The cleat 38 is always in abutment against the sheet 12. This position is illustrated by FIGS. 6 and 7.

Lorsque la platine a été amenée en bout de course, la tige 20 se trouve dans l'orifice de petit diamètre 36 et le taquet s'encliquette dans l'orifice supérieur 34, sous le bord supérieur 40 de celui-ci. Désormais, la platine ne peut être démontée accidentellement. Elle est en effet retenue contre tout retrait, dans un sens perpendiculaire à la tôle, par les rondelles 22, et dans le sens vertical vers le haut, par la mise en butée du taquet 38 contre le bord 40 de l'orifice supérieur. When the plate has been brought to the end of its travel, the rod 20 is located in the orifice of small diameter 36 and the cleat snaps into the upper orifice 34, under the upper edge 40 of the latter. From now on, the plate cannot be dismantled accidentally. It is in fact retained against any withdrawal, in a direction perpendicular to the sheet, by the washers 22, and in the vertical direction upwards, by the abutment of the cleat 38 against the edge 40 of the upper orifice.

Le seul moyen de démonter la platine est de l'écarter à l'aide d'un outil de façon à faire sortir le taquet 38 de l'orifice 34, et de faire glisser la platine vers le haut sur figure 8. The only way to dismantle the plate is to move it apart using a tool so as to remove the cleat 38 from the orifice 34, and to slide the plate upwards in FIG. 8.

Le dispositif de fixation selon l'invention peut être étendu à du matériel anti-vandalisme, en prévoyant un système interdisant le verrouillage du taquet contre son dégagement.  The fixing device according to the invention can be extended to anti-vandalism material, by providing a system prohibiting the locking of the cleat against its release.
