Description

L'invention concerne un dispositif d'enclenchement du genre "bris de glace" destiné à empêcher l'enclenchement intempestif d'un organe d'action.The invention relates to an interlocking device of the "glass breakage" type intended to prevent inadvertent engagement of an action member.

Les "bris de glace" sont bien connus: l'organe d'action, en l'occurrence un bouton-poussoir, est progégé par une glace qu'il faut briser avant de pouvoir l'enclencher."Glass breakage" is well known: the action organ, in this case a push button, is advanced by a glass which must be broken before it can be triggered.

Ce type de protection contre tout enclenchement intempestif a deux inconvénients majeurs:

  • - Projection de petits éclats de verre qui pénètrent dans les revêtements de sol, peuvent être dangereux et sont difficiles à enlever.
  • - Réarmement relativement long, par remplacement du verre brisé par un verre neuf, ce qui interdit les essais de contrôle en grandeur nature.
This type of protection against inadvertent triggering has two major drawbacks:
  • - Projection of small glass fragments which penetrate into the floor coverings, can be dangerous and are difficult to remove.
  • - Relatively long reset, by replacing broken glass with new glass, which prohibits full-scale control tests.

La présente invention a pour objet un dispositif d' enclenchement du genre "bris de glace" évitant ces inconvénients.The subject of the present invention is an interlocking device of the "glass breaking" type, avoiding these drawbacks.

Ce dispositif d'enclenchement est du genre comportant un organe d'action et une plaque disposée au-dessus dudit organe d'action et empêchant toute action intempestive sur celui-ci, et est caractérisé en ce qu'une partie au moins de ladite plaque est élastiquement déformable de manière rever- sible entre deux formes stables, l'une correspondant à une position d'attente, pour laquelle la plaque est bombée vers l'extérieur et laisse ainsi l'organe d'action en position déclenchée, l'autre correspondant à une position d'alarme, pour laquelle la plaque est bombée vers l'intérieur et enclenche de ce fait l'organe d'action.This interlocking device is of the type comprising an action member and a plate disposed above said action member and preventing any untimely action thereon, and is characterized in that at least part of said plate is elastically deformable in a reversible manner between two stable forms, one corresponding to a waiting position, for which the plate is curved outwards and thus leaves the action member in the triggered position, the other corresponding to an alarm position, for which the plate is curved inward and thereby activates the action member.

Le passage de la position d'attente à la position d' alarme s'effectue par une poussée volontaire ou par un choc, par exemple à l'aide d'un marteau; au réarmement, le passage de la position d'alarme à la position d'attente peut se faire directement, à l'aide d'un outil spécialisé, ou par démontage et remontage de l'ensemble, à l'aide d'un outil usuel, par exemple un tournevis.The transition from the standby position to the alarm position is effected by a voluntary push or by a shock, for example using a hammer; upon resetting, the passage from the alarm position to the standby position can be done directly, using a specialized tool, or by disassembly and reassembly of the assembly, using a tool usual, for example a screwdriver.

Quoi qu'il en soit, grâce à l'invention, le passage de l'organe d'action de la position d'attente à la position d' alarme se fait sans réel bris de glace ni projection d'éclats, et la rapidité du réarmement possible autorise des essais en grandeur nature, la brièveté du déclenchement ne pouvant dans ce cas être confondue avec un déclenchement réel.Anyway, thanks to the invention, the passage of the action member from the standby position to the position of alarm occurs without any real glass breakage or projection of splinters, and the possible resetting speed allows full-scale tests, the brevity of the trigger cannot in this case be confused with a real trigger.

D'une manière générale, le dispositif d'enclenchement suivant l'invention comporte un boîtier 1 servant de logement à un bouton-poussoir 2. Un couvercle 3, qui est en forme de cadre, ferme le boîtier 1.In general, the latching device according to the invention comprises a housing 1 serving as a housing for a push button 2. A cover 3, which is in the form of a frame, closes the housing 1.

Dans la forme de réalisation représentée sur les figures 1 à 3, le couvercle 3 est rapporté de manière amovible, par des vis 10, sur le boîtier 1 et est rectangulaire; par deux de ses bords internes opposés, il forme un logement 31, qui est en fait constitué par une échancrure faite dans son épaisseur 3.In the embodiment shown in Figures 1 to 3, the cover 3 is removably attached, by screws 10, on the housing 1 and is rectangular; by two of its opposite internal edges, it forms a housing 31, which is in fact constituted by a notch made in its thickness 3.

Une plaque rectangulaire 4, qui est en matériau élastique, est engagée à force dans ce logement 31, par une partie de sa périphérie, à savoir ses deux bords opposés correspondants; ses dimensions relatives, entre ces deux bords opposés, sont supérieures à celles du logement 31, en sorte qu'elle ne peut pas prendre une forme plane et est au contraire, par élasticité, déformable de manière réversible entre deux formes stables, l'une correspondant à une position d'attente, pour laquelle elleest "bombée" vers l'extérieur du boîtier 1, l'autre correspondant à une position d'alarme, pour laquelle elle est "bombée" vers l' intérieur de celui-ci.A rectangular plate 4, which is made of elastic material, is forcibly engaged in this housing 31, by a part of its periphery, namely its two corresponding opposite edges; its relative dimensions, between these two opposite edges, are greater than those of the housing 31, so that it cannot take a planar shape and is on the contrary, by elasticity, reversibly deformable between two stable shapes, one corresponding to a standby position, for which it is "convex" towards the outside of the housing 1, the other corresponding to an alarm position, for which it is "convex" to the interior thereof.

A la figure 1, la plaque 4 est "bombée" vers l'extérieur du boîtier; elle est alors à distance du bouton-poussoir 2 et celui-ci se trouve en position déclenchée ou "position d'attente".In Figure 1, the plate 4 is "curved" outward from the housing; it is then at a distance from the push button 2 and the latter is in the triggered position or "waiting position".

A la figure 3, suite à une pression ou à un choc, la plaque 4, après franchissement élastique d'une configuration du point mort, est bombée vers l'intérieur du boîtier 1. Le bouton-poussoir 2 étant positionné en conséquence, elle enclenche ce dernier et le maintient dans cette position enclenchée, ou "position d'alarme".In FIG. 3, following a pressure or a shock, the plate 4, after elastic crossing of a neutral configuration, is curved towards the interior of the housing 1. The push button 2 being positioned accordingly, it activates the latter and keeps it in this engaged position, or "alarm position".

Tout réel bris de glace est évité, et le réarmement de la plaque 4, c'est-à-dire son retour en position d'attente, se fait, dans cette forme de réalisation, en désolidarisant le couvercle 3 du boîtier 1, par retrait des vis 10, et en agissant en conséquence sur la plaque 4.Any real glass breakage is avoided, and the rearming of the plate 4, that is to say its return to the waiting position, is done, in this embodiment, by separating the cover 3 from the housing 1, by removal of the screws 10, and acting accordingly on the plate 4.

Dans ce qui précède, le logement 31 du cadre 3 forme par lui-même un moyen de bridage de la plaque 4, qui en maintient comme décrit, la forme bombée, soit dans un sens, soit dans l'autre.In the foregoing, the housing 31 of the frame 3 forms by itself a means of clamping the plate 4, which maintains, as described, the convex shape, either in one direction or in the other.

Dans un autre mode de réalisation, figure 4, la plaque 4 est également élastiquement déformable de manière réversible, mais son moyen de bridage est formé par un cadre rigide 43, distinct du couvercle 3. Ce mode de réalisation permet de loger avec du jeu l'ensemble plaque 4 et cadre 43 dans le logement 31 du couvercle 3, les tolérances de fabrication étant alors moins sévères.In another embodiment, FIG. 4, the plate 4 is also elastically deformable in a reversible manner, but its clamping means is formed by a rigid frame 43, distinct from the cover 3. This embodiment makes it possible to accommodate with play l 'plate 4 and frame 43 in the housing 31 of the cover 3, the manufacturing tolerances then being less severe.

Dans un troisième mode de réalisation, figures 5 et 6, le cadre rigide 43 ainsi associé à la plaque 4 fait corps avec celle-ci. La plaque 4 comporte en fait dans ce cas trois bandes: une bande centrale 41, qui, par déformation plastique, par moulage, déformation à chaud, emboutissage, par exemple, ou autre procédé connu, a été préformée de manière à présenter un bombé et deux bandes latérales 42 et 42', qui sont détachées de la bande centrale 41, et qui sont non déformées et donc planes. La bande 41 supposée déployée à plat estaensiblement plus longue que les bandes 42 et 42'.In a third embodiment, Figures 5 and 6, the rigid frame 43 thus associated with the plate 4 is integral with the latter. The plate 4 in fact comprises in this case three bands: a central band 41, which, by plastic deformation, by molding, hot deformation, stamping, for example, or other known process, has been preformed so as to have a rounded shape and two lateral strips 42 and 42 ', which are detached from the central strip 41, and which are not deformed and therefore flat. The strip 41 assumed to be deployed flat is considerably longer than the strips 42 and 42 ′.

Deux bandes transversales 44, 44', qui font corps avec la bande centrale 41, relient les bandes latérales 42, 42', en formant avec celles-ci le cadre rigide 43 associé.Two transverse bands 44, 44 ', which form one body with the central band 41, connect the lateral bands 42, 42', forming with them the associated rigid frame 43.

Dans un quatrième mode de réalisation, la plaque 4 est de forme circulaire et est préformée globalement en forme de segment sphérique; le logement 31 du couvercle 3 dans lequel elle est engagée par sa périphérie a une forme circulaire appropriée.In a fourth embodiment, the plate 4 is circular in shape and is generally preformed into the shape of a spherical segment; the housing 31 of the cover 3 in which it is engaged by its periphery has an appropriate circular shape.

De manière avantageuse, un joint peut être rapporté sur la plaque 4 de manière à rendre le dispositif étanche.Advantageously, a seal can be attached to the plate 4 so as to seal the device.

Quel que soit le mode de réalisation choisi, la plaque 4 peut, si désiré, être réalisée en matériau transparent, matière synthétique par exemple, rappelant ainsi les "bris de glace" usuels.Whatever the embodiment chosen, the plate 4 can, if desired, be made of transparent material, synthetic material for example, thus recalling the usual "glass breakage".

Le réarmement de la plaque 4 peut, si désiré, s'opérer sans démontage du couvercle 3.The rearming of the plate 4 can, if desired, take place without removing the cover 3.

La figure 8 montre par exemple comment un outil spécialisé 5, introduit dans le boîtier 1 au travers d'une ouverture 11 prévue dans celui-ci et donnant accès à la face inférieure de la plaque 4, permet la remise en forme de celle-ci. De manière avantageuse, l'ouverture 11 est étroite, de telle sorte que seul un outil spécialisé peut y être engagé.Figure 8 shows for example how a specialized tool 5, introduced into the housing 1 through an opening 11 provided therein and giving access to the underside of the plate 4, allows the reshaping thereof . Advantageously, the opening 11 is narrow, so that only a specialized tool can be engaged therein.

Bien entendu, la présente invention ne se limite pas aux formes de réalisation décrites et représentées, mais englobe toute variante d'exécution et/ou de combinaison de leurs divers éléments.Of course, the present invention is not limited to the embodiments described and shown, but encompasses any variant embodiment and / or combination of their various elements.

En particulier, seule une portion de la plaque mise en oeuvre peut être déformable de manière réversible entre deux formes stables; par exemple, s'agissant de la forme circulaire illustrée pour cette plaque à la figure 7, seule la portion centrale d'une telle plaque pourrait être préformée en forme de segment sphérique, le reste de cette plaque étant par ailleurs plan.In particular, only a portion of the plate used can be reversibly deformable between two stable forms; for example, with regard to the circular shape illustrated for this plate in FIG. 7, only the central portion of such a plate could be preformed into the shape of a spherical segment, the rest of this plate being otherwise plane.

En outre, l'organe d'action qu'elle commande, n'est pas nécessairement un bouton-poussoir; il pourrait par exemple s'agir directement d'un contact électrique.In addition, the action member it controls is not necessarily a push button; it could for example be directly an electrical contact.

De plus, un tel organe d'action peut être soit rapporté sur le boîtier qui le contient, soit être intégré à celui-ci.In addition, such an action member can either be attached to the housing which contains it, or be integrated therein.

Ce boîtier, quant à lui, peut être rapporté en saillie sur une quelconque surface de support, ou encastré dans celle-ci, avec par exemple, suivant des modalités connues, une fixation à vis ou à griffes.This box, meanwhile, can be attached projecting on any support surface, or embedded therein, with for example, according to known methods, a fixing screw or claws.

Enfin, on notera que, en cas de nécessité, en l'absence momentanée de disponibilité de plaque suivant l'invention, une telle plaque peut être remplacée par une plaque en verre traditionnel, et le dispositif d'enclenchement, être encore, malgré tout, opératif.Finally, it will be noted that, if necessary, in the momentary absence of availability of a plate according to the invention, such a plate can be replaced by a traditional glass plate, and the interlocking device can still be, despite everything , operative.
