Description

La présente invention concerne un dispositif inviolable à bouton-poussoir, pour la commande des mécanismes de chasse des réservoirs de chasse d'eau.The present invention relates to a tamper-proof push-button device for controlling the flushing mechanisms of flushing tanks.

De manière plus particulièrement intéressante, quoique nullement limitative, ce dispositif inviolable à bouton-poussoir peut être utilisé pour la commande des mécanismes de chasse du genre comprenant notamment:

  • - une enveloppe tubulaire extérieure comportant une portion inférieure renflée ou cloche extérieure et destinée à être installée fixement à l'intérieur d'une cuve ou réservoir;
  • - un culot pourvu d'une ouverture centrale appelée à constituer l'orifice de vidange du réservoir et de moyens de fixation permettant son assemblage amovible à la base de la cloche extérieure, ce culot étant appelé à être installé fixement sur l'ouverture inférieure du réservoir;
  • - et un équipage mobile logé, avec une aptitude de déplacement axial, à l'intérieur de l'enveloppe extérieure, et susceptible d'être actionné par le bouton-poussoir, cet équipage mobile comprenant un clapet d'obturation de l'orifice de vidange installé à la partie inférieure d'un tube d'évacuation de trop-plein ou tube de surverse ouvert à ses extrémités et dont la portion inférieure est équipée d'un flotteur constitué par une cloche disposée autour de la partie basse dudit tube de surverse ou par un renflement de ladite portion inférieure.
More particularly advantageously, although in no way limiting, this tamper-proof push-button device can be used for controlling hunting mechanisms of the kind comprising in particular:
  • - an outer tubular casing comprising a bulged lower portion or outer bell and intended to be fixedly installed inside a tank or tank;
  • - A base provided with a central opening called to constitute the emptying orifice of the tank and fixing means allowing its removable assembly at the base of the external bell, this base being called to be installed fixedly on the lower opening of the tank;
  • - And a mobile unit housed, with an axial displacement aptitude, inside the outer envelope, and capable of being actuated by the push button, this mobile unit comprising a shutter valve for the orifice of drain installed at the lower part of an overflow evacuation tube or overflow tube open at its ends and the lower portion of which is equipped with a float constituted by a bell arranged around the lower part of said overflow tube or by a bulge of said lower portion.

Un inconvénient sérieux des boutons-poussoirs actuels de commande des dispositifs de chasse comme EP-A-0 124 458, qui sont pourtant moins exposés que les autres moyens de commande (tirettes, manettes basculantes, etc.) installés sur le couvercle des réservoirs, est qu'ils peuvent être assez facilement démontés, de sorte que par suite d'actes de vandalisme ou de malveillance, les chasses d'eau installées dans les toilettes des lieux publics sont souvent privées de leur bouton de commande, ce qui les place dans l'incapacité de fonctionner.A serious drawback of current push buttons for controlling flushing devices such as EP-A-0 124 458, which are however less exposed than the other control means (pull tabs, tilting levers, etc.) installed on the tank cover, is that they can be quite easily disassembled, so that as a result of vandalism or malicious acts, the flushing devices installed in the toilets of public places are often deprived of their control button, which places them in the inability to function.

Un objet de la présente invention est de remédier à cet inconvénient.An object of the present invention is to remedy this drawback.

Selon l'invention, cet objectif est atteint au moyen d'un dispositif de commande à bouton-poussoir comprenant:

  • - un bouton-poussoir;
  • - une coupelle ouverte à ses extrémités et dans la partie supérieure de laquelle est logé, avec une aptitude de mouvement axial, ledit bouton-poussoir, cette coupelle comportant un épaulement circulaire permettant son appui sur la surface extérieure du bord du trou ménagé dans le couvercle du réservoir;
  • - une bague de dissuasion ayant, de préférence, une forme tronconique montée à rotation libre autour de la partie de ladite coupelle destinée à être installée à l'extérieur dudit réservoir.
According to the invention, this objective is achieved by means of a push-button control device comprising:
  • - a push button;
  • - A cup open at its ends and in the upper part of which is housed, with an axial movement ability, said push button, this cup having a circular shoulder allowing its support on the outside surface of the edge of the hole made in the cover of the tank;
  • - A deterrent ring preferably having a frustoconical shape mounted for free rotation around the part of said cup intended to be installed outside said tank.

Grâce à cette construction, il est très difficile d'extraire le bouton-poussoir de la coupelle ou d'entraîner ladite coupelle en rotation, tandis qu'il est pratiquement impossible d'exercer, sur cette dernière, un effort manuel de traction important susceptible d'entraîner son arrachement et celui dudit bouton-poussoir.Thanks to this construction, it is very difficult to extract the push-button from the cup or to drive said cup in rotation, while it is practically impossible to exert, on the latter, a significant manual traction force which is likely to to cause its tearing and that of said push button.

Selon une autre caractéristique, la coupelle est pourvue, à sa périphérie et sur une portion de sa hauteur, d'une pluralité de gorges ayant un profil en dents de loup et le dispositif de commande selon l'invention comprend encore une bague de sécurité comportant une collerette d'arrêt destinée à être positionnée au-dessous de la face inférieure du bord dudit trou, cette bague étant dotée d'au moins une dent de retenue ayant un profil complémentaire à celui desdites gorges et appelée à coopérer avec l'une de ces dernières de façon à interdire tout mouvement axial de la coupelle tendant à la séparer de ladite bague.According to another characteristic, the cup is provided, at its periphery and over a portion of its height, with a plurality of grooves having a wolf tooth profile and the control device according to the invention also comprises a safety ring comprising a stop collar intended to be positioned below the underside of the edge of said hole, this ring being provided with at least one retaining tooth having a profile complementary to that of said grooves and called to cooperate with one of the latter so as to prevent any axial movement of the cup tending to separate it from said ring.

Grâce à l'adjonction de cette caractéristique complémentaire, il est tout à fait impossible d'arracher manuellement la coupelle dans laquelle est logé le bouton-poussoir.Thanks to the addition of this additional characteristic, it is completely impossible to manually tear off the cup in which the push button is housed.

Selon une autre caractéristique, le bouton-poussoir comporte une tige tubulaire montée, avec une aptitude de coulissement axial, dans un prolongement inférieur cylindrique de la coupelle, et l'extrémité inférieure de cette tige est pourvue d'une saillie disposée hors dudit prolongement cylindrique et au-dessous de l'extrémité de ce dernier.According to another characteristic, the push button comprises a tubular rod mounted, with an axial sliding ability, in a cylindrical lower extension of the cup, and the lower end of this rod is provided with a projection disposed outside said cylindrical extension and below the end of the latter.

Grâce à cette disposition, il est impossible d'arracher le bouton-poussoir.Thanks to this arrangement, it is impossible to tear off the push button.

On conçoit que la combinaison des caractéristiques ci-dessus permet de réaliser un dispositif de commande à bouton-poussoir pratiquement inviolable sans l'aide d'outils.It is understood that the combination of the above characteristics makes it possible to produce a practically tamper-resistant push button control device without the aid of tools.

Les buts, caractéristiques et avantages ci-dessus, et d'autres encore, ressortiront mieux de la description qui suit et des dessins annexés dans lesquels:The aims, characteristics and advantages above, and others still, will emerge more clearly from the description which follows and from the appended drawings in which:

La figure 10 est une vue en coupe axiale du bouton- poussoir du dispositif de commande.Figure 10 is an axial sectional view of the push button of the control device.

On se réfère auxdits dessins pour décrire un mode d'exécution intéressant, quoique nullement limitatif, du dispositif de commande inviolable selon l'invention.Reference is made to said drawings to describe an interesting, although in no way limiting, embodiment of the tamper-evident control device according to the invention.

Ce dispositif de commande est généralement destiné à être installé dans une position verticale ou sensiblement verticale sur les couvercles des cuves ou réservoirs de chasse d'eau. Pour cette raison et pour faciliter la description de l'invention, on utilise des termes tels que "superieur" et "inférieur" dans la suite du présent exposé. Il est évident cependant que l'emploi de tels mots ne saurait avoir un caractère limitatif, car il n'est pas exclu que le dispositif de commande inviolable selon l'invention puisse être installé autrement que dans une position verticale.This control device is generally intended to be installed in a vertical or substantially vertical position on the lids of flush tanks or reservoirs. For this reason and to facilitate the description of the invention, terms such as "upper" and "lower" are used in the remainder of this description. It is obvious, however, that the use of such words cannot be limiting, since it cannot be excluded that the tamper-evident control device according to the invention can be installed other than in a vertical position.

Comme illustré à la figure 1, ce dispositif peut être avantageusement utilisé pour la commande des mécanismes de chasse du genre comprenant, de façon connue, une enveloppe tubulaire extérieure 1 comportant une portion supérieure cylindrique la et une portion inférieure renflée ou cloche extérieure 1 b. L'extrémité supérieure de la portion haute la de cette enveloppe extérieure est munie d'un chapeau 1c pourvu d'un orifice axial taraudé 1d.As illustrated in FIG. 1, this device can be advantageously used for controlling flushing mechanisms of the type comprising, in known manner, an outer tubular casing 1 comprising an upper cylindrical portion 1a and a bulged lower portion or outer bell 1b. The upper end of the upper portion 1a of this outer casing is provided with a cap 1c provided with a tapped axial orifice 1d.

Dans l'enveloppe extérieure 1 est logé, avec une aptitude de mouvement axial ascendant ou descendant, un tube de "surverse" ou tube d'évacuation de trop-plein 2 à l'extrémité inférieure duquel est fixé le clapet 3 d'obturation de l'orifice de vidange du réservoir.In the outer casing 1 is housed, with a capacity for axial upward or downward movement, a "overflow" tube or overflow discharge tube 2 at the lower end of which is fixed the shutter 3 the tank drain hole.

La portion inférieure du tube de surverse est agencée de manière à constituer un flotteur qui peut être formé par une cloche 4 disposée autour de la portion basse dudit tube de surverse 2, ou par la partie inférieure renflée de ce dernier.The lower portion of the overflow tube is arranged so as to constitute a float which can be formed by a bell 4 arranged around the lower portion of said overflow tube 2, or by the bulged lower part of the latter.

D'autre part, un tel mécanisme de chasse comprend encore un culot 5 comportant un orifice central 0 dont le bord circulaire supérieur 5a forme le siège du clapet 3.On the other hand, such a flushing mechanism also comprises a base 5 comprising a central orifice 0 whose upper circular edge 5a forms the seat of the valve 3.

Le culot 7 et la base de la cloche extérieure 1 b sont pourvus de moyens de jonction complémentaires permettant de les assembler de manière amovible, tout en autorisant le passage de l'eau entre ladite base et ledit culot.The base 7 and the base of the outer bell 1 b are provided with complementary joining means making it possible to assemble them in a removable manner, while allowing the passage of water between said base and said base.

Lorsque le dispositif de chasse est installé dans un réservoir lui-même fixé sur une cuvette 6 de cabinet d'aisances partiellement représentée à la figure 1, il est immobilisé à l'intérieur dudit réservoir:

  • - d'une part, au moyen de son dispositif de commande installé sur le couvercle 7a (partiellement représenté) du réservoir et dont un organe fileté est vissé dans l'écrou constitué par le chapeau 1c formant le sommet de l'enveloppe extérieure 1 ;
  • - d'autre part, au moyen du culot 5 installé fixement, à l'aide d'un écrou 8 se vissant sur sa portion cylindrique inférieure filetée 5b, dans l'orifice 9 que présente le fond 7 du réservoir (partiellement illustré), de sorte que l'orifice central 0 dudit culot constitue l'orifice de vidange du réservoir.
When the flushing device is installed in a tank itself fixed on a toilet cabinet bowl 6 partially shown in FIG. 1, it is immobilized inside said tank:
  • - On the one hand, by means of its control device installed on the cover 7a (partially shown) of the reservoir and of which a threaded member is screwed into the nut constituted by the cap 1c forming the top of the outer envelope 1;
  • - on the other hand, by means of the base 5 fixedly installed, using a nut 8 screwing onto its threaded lower cylindrical portion 5b, in the orifice 9 presented by the bottom 7 of the tank (partially illustrated), so that the central orifice 0 of said base constitutes the emptying orifice of the tank.

Selon le mode d'exécution intéressant illustré, le culot 5 porte une traverse 10 disposée fixement au travers de son orifice central 0, au-dessous du siège 5a du clapet 3. Sur cette traverse 10, prend appui l'organe de soulèvement dudit clapet, constitué par une came 11 disposée au-dessous de celui-ci et monté avec une aptitude de pivotement à l'extrémité inférieure d'une tige de transmission 12 susceptible d'être repoussée par le bouton-poussoir du dispositif de commande.According to the interesting embodiment illustrated, the base 5 carries a cross member 10 fixedly disposed through its central orifice 0, below the seat 5a of the valve 3. On this cross member 10, the lifting member of said valve bears. , constituted by a cam 11 disposed below it and mounted with a pivoting ability at the lower end of a transmission rod 12 capable of being pushed back by the push button of the control device.

Le dispositif de commande inviolable selon l'invention comprend principalement:

  • - un bouton-poussoir 13;
  • - une coupelle 14 dans laquelle est logé ce bouton-poussoir;
  • - et une bague 15 montée à rotation libre autour de ladite coupelle.
The tamper-evident control device according to the invention mainly comprises:
  • - a push button 13;
  • - A cup 14 in which is housed this push button;
  • - And a ring 15 mounted for free rotation around said cup.

La coupelle 14 comprend une cuvette ou enveloppe cylindrique supérieure 14a destinée à être installée au-dessus du couvercle 7a du réservoir et un prolongement cylindrique inférieur 14b ayant un diamètre plus réduit que celui de ladite cuvette et le même axe que celle-ci, ce prolongement traversant ledit couvercle et pénétrant à l'intérieur du réservoir lorsque le dispositif de commande est monté sur ce dernier.The cup 14 comprises an upper cylindrical bowl or casing 14a intended to be installed above the cover 7a of the tank and a lower cylindrical extension 14b having a smaller diameter than that of said bowl and the same axis as the latter, this extension passing through said cover and penetrating inside the tank when the control device is mounted on the latter.

La coupelle ainsi conformée est ouverte à ses extrémités et elle comporte un épaulement circulaire 14c correspondant au fond de sa cuvette supérieure et permettant son appui sur la face supérieure 7a' du bord du trou 16 ménagé dans le couvercle 7a pour l'installation du dispositif de commande.The cup thus shaped is open at its ends and it has a circular shoulder 14c corresponding to the bottom of its upper bowl and allowing it to rest on the upper face 7a 'of the edge of the hole 16 formed in the cover 7a for the installation of the device. ordered.

Le prolongement cylindrique inférieur 14b de la coupelle est doté d'un filetage 14d, par exemple sur une portion de sa longueur s'étendant de son extrémité inférieure jusqu'à une faible distance de son rattachement à la cuvette 14a de ladite coupelle.The lower cylindrical extension 14b of the cup has a thread 14d, for example over a portion of its length extending from its lower end to a short distance from its attachment to the bowl 14a of said cup.

Ce filetage permet le vissage du prolongement cylindrique 14b de la coupelle dans le chapeau taraudé 1c de l'enveloppe extérieure 1 du mécanisme de chasse proprement dit.This thread allows the cylindrical extension 14b of the cup to be screwed into the threaded cap 1c of the outer casing 1 of the flushing mechanism proper.

Lorsque le dispositif de commande est en place, la coupelle 14 prend appui sur la face supérieure du bord du trou 16, par l'intermédiaire de son épaulement 14c, et elle est rigidement assemblée à l'enveloppe extérieure installée à l'intérieur du réservoir 7 - 7a par l'intermédiaire de son prolongement fileté 14b vissé dans le chapeau 1c de ladite enveloppe.When the control device is in place, the cup 14 bears on the upper face of the edge of the hole 16, by means of its shoulder 14c, and it is rigidly assembled with the outer envelope installed inside the tank. 7 - 7a by means of its threaded extension 14b screwed into the cap 1c of said envelope.

Le bouton-poussoir 13 est logé, avec une aptitude de déplacement axial, dans la coupelle 14.The push button 13 is housed in the cup 14 with the ability to move axially.

Il se compose d'une tête circulaire 13a et d'une tige tubulaire 13b s'étendant au-dessous de ladite tête et ayant le même axe que cette dernière. Dans cette tige tubulaire est logée et calée la partie terminale supérieure de la tige de transmission 12, lorsque le dispositif de commande est en place (figures 1 à 3).It consists of a circular head 13a and a tubular rod 13b extending below said head and having the same axis as the latter. In this tubular rod is housed and wedged the upper end portion of the transmission rod 12, when the control device is in place (Figures 1 to 3).

La tige tubulaire 13b du bouton-poussoir a une longueur L1 supérieure à la longueur L2 du prolongement cylindrique 14b de la coupelle.The tubular rod 13b of the push button has a length L1 greater than the length L2 of the cylindrical extension 14b of the cup.

La tête 13a et la tige tubulaire 13b du bouton-poussoir ont des diamètres D1, D2 inférieurs aux diamètres intérieurs D3, D4 de la cuvette 14a et du prolongement cylindrique 14b de la coupelle dans lesquels ils sont respectivement montés, de façon à autoriser un coulissement sans jeu excessif de ladite tête et de ladite tige tubulaire dans ladite cuvette et dans ledit prolongement cylindrique, respectivement.The head 13a and the tubular rod 13b of the push button have diameters D1, D2 smaller than the internal diameters D3, D4 of the bowl 14a and of the cylindrical extension 14b of the cup in which they are respectively mounted, so as to allow sliding. without excessive play of said head and said tubular rod in said bowl and in said cylindrical extension, respectively.

L'extrémité inférieure du bouton-poussoir 13 est pourvue d'une saillie qui est, par exemple, constituée par un épaulement circulaire d'arrêt 13c.The lower end of the push button 13 is provided with a projection which is, for example, constituted by a circular stop shoulder 13c.

Lorsque le bouton-poussoir 13 est installé dans la coupelle 14 (figures 2 et 3), cet épaulement circulaire 13c se trouve placé hors du prolongement cylindrique 14b de ladite coupelle et au-dessous de l'extrémité inférieure dudit prolongement cylindrique.When the push button 13 is installed in the cup 14 (Figures 2 and 3), this circular shoulder 13c is placed outside the cylindrical extension 14b of said cup and below the lower end of said cylindrical extension.

Afin de faciliter le montage du bouton-poussoir dans la coupelle, l'extrémité inférieure 13d de la tige tubulaire 13b dudit bouton-poussoir a une forme conique et elle comporte des fentes longitudinales 13e.In order to facilitate mounting of the push button in the cup, the lower end 13d of the tubular rod 13b of said push button has a conical shape and it has longitudinal slots 13e.

La bague 15 a avantageusement une forme tronconique.The ring 15 advantageously has a frustoconical shape.

Elle a une hauteur H au moins égale ou sensiblement égale à la hauteur h de la portion de la cuvette 14a qui doit être disposée au-dessus de la surface supérieure 7a' du couvercle 7a du réservoir. Lorsque la cuvette 14a de la coupelle 14 est appelée à être disposée entièrement au-dessus du couvercle (figures 2 et 3), la hauteur H de la bague est donc égale ou sensiblement égale à la hauteur h de ladite cuvette; de manière à entourer celle-ci sur la totalité de sa hauteur.It has a height H at least equal to or substantially equal to the height h of the portion of the bowl 14a which must be disposed above the upper surface 7a 'of the cover 7a of the reservoir. When the bowl 14a of the cup 14 is called to be disposed entirely above the cover (FIGS. 2 and 3), the height H of the ring is therefore equal or substantially equal to the height h of said bowl; so as to surround it over its entire height.

La bague de dissuasion 15 est montée folle autour de la cuvette 14a et elle est immobilisée en translation axiale par rapport à cette dernière.The deterrent ring 15 is mounted loosely around the bowl 14a and it is immobilized in axial translation relative to the latter.

La bague de dissuasion 15 comporte, par exemple, dans ce but, une nervure circulaire interne 15a logée dans des encoches 14e ménagées à la périphérie de la cuvette 14a de la coupelle.The deterrent ring 15 comprises, for example, for this purpose, an internal circular rib 15a housed in notches 14e formed at the periphery of the bowl 14a of the cup.

La nervure 15a est avantageusement disposée à proximité de l'extrémité supérieure de la bague tournante 15 et les encoches 14e sont prévues à la partie supérieure épaissie 14f de la cuvette 14. Cette dernière comporte, par exemple, quatre encoches 14e espacées de 90 degrés. Les bossages 14g qui délimitent les encoches 14e dans leur partie basse (figure 6) présentent des pentes 14h convergentes en direction du bas. Lors de l'assemblage de la coupelle 14 et de la bague tournante 15, ces pentes 14h et le nombre limité de bossage 14g (et d'encoches 14e) facilitent l'enfoncement, à force, de ladite coupelle dans ladite bague tournante, jusqu'à ce que la nervure circulaire interne 15a de cette dernière viennent s'engager dans les encoches 14e de la cuvette 14a.The rib 15a is advantageously disposed near the upper end of the rotating ring 15 and the notches 14e are provided in the thickened upper part 14f of the bowl 14. The latter comprises, for example, four notches 14e spaced 90 degrees apart. The bosses 14g which delimit the notches 14e in their lower part (FIG. 6) have slopes 14h which converge in the direction of the bottom. During the assembly of the cup 14 and the rotating ring 15, these slopes 14h and the limited number of boss 14g (and notches 14e) facilitate the insertion, by force, of said cup into said rotating ring, up to 'that the internal circular rib 15a of the latter come to engage in the notches 14e of the bowl 14a.

Le dispositif de commande inviolable selon l'invention comprend encore, avantageusement, une bague de sécurité 17 (figure 7) apte à être montée à rotation libre autour d'une portion de la coupelle 14 et dont une partie au moins est destinée à être immobilisée au-dessous du bord du trou 16 ménagé dans le couvercle 7a de la cuve ou réservoir, ladite bague de sécurité et ladite coupelle étant dotées de moyens complémentaires de liaison en translation.The tamper-evident control device according to the invention also advantageously comprises a safety ring 17 (FIG. 7) capable of being mounted in free rotation around a portion of the cup 14 and of which at least part is intended to be immobilized below the edge of the hole 16 formed in the cover 7a of the tank or reservoir, said safety ring and said cup being provided with complementary means of connection in translation.

Selon le mode d'exécution intéressant illustré, cette bague de sécurité 17 comporte une partie cylindrique 17a destinée à entourer une portion de la coupelle 14 et permettant son montage sur celle-ci, et une collerette d'arrêt inférieure 17b appelée à être placée au-dessous du bord du trou 16, la partie cylindrique 17a ayant un diamètre inférieur à celui dudit trou, de façon à pouvoir être engagée dans ce dernier, lorsque le dispositif de commande est monté sur le couvercle; ladite partie cylindrique ayant, d'autre part, une hauteur un peu supérieure à l'épaisseur dudit couvercle.According to the interesting embodiment illustrated, this safety ring 17 comprises a cylindrical part 17a intended to surround a portion of the cup 14 and allowing it to be mounted thereon, and a lower stop collar 17b intended to be placed at the below the edge of the hole 16, the cylindrical part 17a having a diameter less than that of said hole, so that it can be engaged in the latter when the control device is mounted on the cover; said cylindrical part having, on the other hand, a height slightly greater than the thickness of said cover.

Suivant ce mode d'exécution, la portion cylindrique 17a de la bague de sécurité est destinée à être disposée à rotation libre et bloquée en translation autour de l'extrémité supérieure 14i du prolongement cylindrique inférieur 14b de la coupelle 14, juste au-dessous de la cuvette supérieure 14a de cette dernière.According to this embodiment, the cylindrical portion 17a of the safety ring is intended to be disposed in free rotation and locked in translation around the upper end 14i of the lower cylindrical extension 14b of the cup 14, just below the upper bowl 14a of the latter.

Dans ce but, l'extrémité supérieure 14i du prolongement cylindrique 14b est pourvue d'au moins une gorge périphérique 14j ou, de préférence, d'une pluralité de gorges périphériques successives ou superposées 14j. Ces gorges périphériques ont un profil en dents de loup (figure 5).For this purpose, the upper end 14i of the cylindrical extension 14b is provided with at least one peripheral groove 14j or, preferably, a plurality of successive or superimposed peripheral grooves 14j. These peripheral grooves have a wolf tooth profile (Figure 5).

D'autre part, la bague de sécurité 17 est pourvue, à son extrémité supérieure, d'une dent ou lèvre circulaire 17c orientée vers l'intérieur. Cette dent ou lèvre interne 17c a un profil complémentaire au profil des gorges 14j.On the other hand, the safety ring 17 is provided, at its upper end, with a circular tooth or lip 17c oriented inwards. This tooth or internal lip 17c has a profile complementary to the profile of the grooves 14j.

Lorsque la bague de sécurité 17 est enfilée sur le prolongement cylindrique 14b de la coupelle, la face pentée 17d de sa dent ou lèvre de retenue 17c glisse sur la face pentée 14k des dents de loup jusqu'à ce que ladite bague de sécurité vienne buter contre le fond de la cuvette 14a par l'intermédiaire de son extrémité supérieure, ou contre la face inférieure du couvercle 7a du réservoir par l'intermédiaire de sa collerette 17b.When the safety ring 17 is threaded on the cylindrical extension 14b of the cup, the steep face 17d of its tooth or retaining lip 17c slides on the steep face 14k of the wolf teeth until said safety ring comes to abut against the bottom of the bowl 14a via its upper end, or against the underside of the cover 7a of the tank via its collar 17b.

Par contre, le profit en dents de loup des gorges 14j, empêche tout mouvement axial contraire de la bague de sécurité 17 par rapport à la coupelle, la dent ou lèvre 17c ne pouvant s'échapper de la gorge 14j dans laquelle elle est retenue.On the other hand, the profit in wolf teeth of the grooves 14j prevents any opposite axial movement of the safety ring 17 relative to the cup, the tooth or lip 17c being unable to escape from the groove 14j in which it is retained.

On observe que la liaison de la bague de sécurité 17 et du prolongement cylindrique 14b de la coupelle s'opère dans l'épaisseur du couvercle 7a, lorsque le dispositif de commande est installé sur ledit couvercle. Il n'est donc pas possible de démonter la bague de sécurité sans l'aide d'un outil approprié.It is observed that the connection of the safety ring 17 and the cylindrical extension 14b of the cup takes place in the thickness of the cover 7a, when the control device is installed on said cover. It is therefore not possible to disassemble the safety ring without using an appropriate tool.

D'autre part, la coupelle peut être entraînée en rotation, pour permettre son vissage sur la partie fixe 1 du mécanisme de chasse proprement dit, ou son dévissage pour avoir accès au réservoir ou au robinet flotteur équipant intérieurement ce dernier.On the other hand, the cup can be rotated, to allow it to be screwed onto the fixed part 1 of the flushing mechanism itself, or unscrewed to gain access to the tank or to the float valve fitted inside it.
