  • the figure 1 is a perspective view in broken section of an electronic device;
  • the figure 2 represents a frontal view of the broken section of the figure 1 ;
  • the figure 3 represents a section of the electronic device, perpendicular to that of the figure 2 ;
  • the figure 4 represents a side view of an intermediate member of the electronic device; and
  • the figure 5 represents a perspective view of the intermediate member.

Un dispositif électronique 1 représenté sur les figures 1 à 3 comprend un boîtier cylindrique 2, par exemple en une matière plastique, composé d'une embase 3 et d'un couvercle 4 qui peuvent être accouplés l'un au-dessus de l'autre par tous moyens d'accouplement appropriés (non représentés), par exemple par encliquetage, et qui, en position accouplée, délimitent entre eux une chambre 5.An electronic device 1 represented on the Figures 1 to 3 comprises a cylindrical housing 2, for example a plastic material, consisting of a base 3 and a cover 4 which can be coupled one above the other by any means coupling means (not shown), for example by snapping, and which, in the coupled position, delimit between them a chamber 5.

Dans la chambre 5 est installée une carte électronique 6, maintenue par exemple par conjugaison de formes, dans une position telle qu'elle est située à distance d'une paroi frontale 7 du couvercle 4 et parallèlement à cette dernière.In the chamber 5 is installed an electronic card 6, maintained for example by conjugation of shapes, in a position such that it is located at a distance from a front wall 7 of the lid 4 and parallel to the latter.

La carte électronique 6 porte, du côté de la paroi frontale 7, un élément lumineux 8, tel qu'une diode électroluminescente, et un commutateur électrique 9, tel qu'un bouton poussoir, situé à proximité de l'élément lumineux 8.The electronic card 6 carries, on the side of the front wall 7, a light element 8, such as a light-emitting diode, and an electric switch 9, such as a push button, located near the light element 8.

La paroi frontale 7 du couvercle 4 présente une ouverture 10 aménagée en face de l'élément lumineux 8, dont le bord périphérique forme un épaulement tronconique 10a tourné du côté de la chambre 5.The front wall 7 of the cover 4 has an opening 10 arranged in front of the light element 8, the peripheral edge of which forms a frustoconical shoulder 10a turned towards the chamber 5.

L'ouverture 10 est recouverte par une plaque 11 en une matière transparente ou translucide, se présentant par exemple sous la forme d'un disque. Le bord périphérique 11a de la plaque 11 est en appui de l'intérieur vers l'extérieur sur le bord périphérique 10a de l'ouverture 10 par conjugaison de formes.The opening 10 is covered by a plate 11 in a transparent or translucent material, for example in the form of a disk. The peripheral edge 11a of the plate 11 bears from the inside to the outside on the peripheral edge 10a of the opening 10 by conjugation of shapes.

Dans la chambre 5 est placé un organe intermédiaire 12 qui s'étend entre la carte électronique 6 et la paroi frontale 7 du couvercle 4.In the chamber 5 is placed an intermediate member 12 which extends between the electronic card 6 and the front wall 7 of the cover 4.

Comme illustré sur les figures 4 et 5, l'organe intermédiaire 12 comprend une partie conique 13 dont le sommet 13a présente un trou traversant 14, une partie annulaire 15 qui prolonge le bord de l'ouverture de la partie conique 13, radialement à l'axe de cette dernière, une partie de fixation 16 située latéralement et à distance de la partie conique 13, une branche de liaison 17 qui relie la partie annulaire 15 et la partie de fixation 16, ainsi que deux pattes de soutien en saillie 18 reliées à la partie annulaire 15 et opposées à la branche de liaison 17. L'organe intermédiaire 12 présente substantiellement un plan de symétrie contenant l'axe de la partie conique 13, la partie de fixation 16, la branche de liaison 17 et les pattes de soutien 18 sont agencées symétriquement. En outre, la partie conique 13 est munie sur sa face extérieure d'un doigt ou portion en saillie 19 situé à distance du trou 14 et s'étendant du côté de son sommet 13a.As illustrated on Figures 4 and 5 , the intermediate member 12 comprises a conical portion 13 whose top 13a has a through hole 14, an annular portion 15 which extends the edge of the opening of the conical portion 13, radially to the axis thereof, a portion fastening 16 located laterally and away from the conical portion 13, a connecting leg 17 which connects the annular portion 15 and the attachment portion 16, and two projecting support legs 18 connected to the annular portion 15 and opposite to The connecting member 17. The intermediate member 12 has substantially a plane of symmetry containing the axis of the conical portion 13, the attachment portion 16, the connecting leg 17 and the support legs 18 are arranged symmetrically. In addition, the part conical 13 is provided on its outer face with a finger or projecting portion 19 located at a distance from the hole 14 and extending on the side of its top 13a.

L'organe intermédiaire 12 est par exemple en une matière plastique et est tel que, si la partie de fixation 16 est tenue et la partie conique 13 est sollicitée par une pression par exemple sur la partie annulaire 15, la partie conique 13 peut être déplacée en déformant la branche de liaison 17 et/ou les jonctions entre cette dernière et la partie annulaire 15 et/ou la partie de fixation 16, à l'encontre de son élasticité de la matière, depuis une position neutre et, sur une course relativement faible, selon approximativement l'axe de la partie conique 13.The intermediate member 12 is for example of a plastic material and is such that, if the fixing portion 16 is held and the conical portion 13 is urged by a pressure for example on the annular portion 15, the conical portion 13 can be moved by deforming the connecting branch 17 and / or the junctions between the latter and the annular part 15 and / or the fixing part 16, against its elasticity of the material, from a neutral position and, over a relatively short stroke low, approximately along the axis of the conical portion 13.

Comme illustré sur les figures 1 à 3, l'organe intermédiaire 12 est, dans une position de repos, installé dans le boîtier 2 de la manière suivante.As illustrated on Figures 1 to 3 , the intermediate member 12 is, in a rest position, installed in the housing 2 in the following manner.

La partie conique 13 est située entre la carte électronique 6 et la plaque 11. Son axe s'étend perpendiculairement à la carte électronique 6 et à la paroi frontale 7 et passe sensiblement au milieu de l'élément lumineux 8 et de la plaque 11.The conical portion 13 is located between the electronic card 6 and the plate 11. Its axis extends perpendicularly to the electronic card 6 and the front wall 7 and passes substantially in the middle of the light element 8 and the plate 11.

L'ouverture de la partie conique 13 est tournée du côté de la plaque 11 et la partie annulaire 15 est en appui contre la partie périphérique de la face intérieure de la plaque 11. Ainsi, la plaque 11 est interposée et maintenue par conjugaison de formes entre la paroi frontale 7 du couvercle 4 et l'organe intermédiaire 12.The opening of the conical portion 13 is turned on the side of the plate 11 and the annular portion 15 bears against the peripheral portion of the inner face of the plate 11. Thus, the plate 11 is interposed and maintained by conjugation of shapes between the front wall 7 of the cover 4 and the intermediate member 12.

Le sommet 13a de la partie conique 13 est situé du côté et à faible distance de la carte électronique 6. L'élément lumineux 8 est en face du trou traversant 14 et pénètre éventuellement dans ce dernier, librement.The top 13a of the conical portion 13 is located on the side and at a short distance from the electronic card 6. The light element 8 is in front of the through hole 14 and possibly enters the latter freely.

La partie de fixation 16 est accouplée à la paroi frontale 7 du couvercle 4. Par exemple, la paroi frontale 7 et la partie de fixation 16 présentent respectivement deux trous de maintien 20 et deux parties en saillie de maintien 21 engagées à force les unes dans les autres perpendiculairement à la paroi frontale 7.The fixing portion 16 is coupled to the front wall 7 of the cover 4. For example, the front wall 7 and the fixing portion 16 respectively have two holding holes 20 and two holding projecting portions 21 forcibly engaged with each other. the others perpendicular to the front wall 7.

La portion en saillie 19 est située au-dessus du commutateur électrique 5 et ne sollicite pas ce dernier.The protruding portion 19 is located above the electrical switch 5 and does not solicit the latter.

Les pattes de soutien 18 sont engagées dans des logements 22 aménagés sur la paroi frontale 7 du couvercle 4. Les extrémités des pattes 18 sont, localement, en appui sur des portions 22a de ces logements 22 opposées à la paroi frontale 7The support lugs 18 are engaged in housings 22 arranged on the front wall 7 of the cover 4. The ends of the lugs 18 are, locally, bearing on portions 22a of these housings 22 opposite to the front wall 7

Ainsi, la partie conique 13 est montée sur la paroi frontale 7 en porte-à-faux ou suspendue par rapport à sa partie de fixation 16 et par rapport aux pattes de soutien 18 et la partie annulaire 15 exerce une faible pression sur la plaque 11 dans le sens de son appui sur la paroi frontale 7, sous l'effet d'une faible déformation élastique de la branche de liaison 17 et des pattes de soutien 18 et/ou de leurs jonctions avec la partie annulaire 15 et/ou la partie de fixation 16. La partie conique 13 et sa portion en saillie d'actionnement 19 sont mobiles depuis ladite position de repos.Thus, the conical portion 13 is mounted on the front wall 7 cantilevered or suspended relative to its fixing portion 16 and relative to the support lugs 18 and the annular portion 15 exerts a low pressure on the plate 11 in the direction of its support on the front wall 7, under the effect of a small elastic deformation of the connecting leg 17 and the support lugs 18 and / or their junctions with the annular portion 15 and / or the portion 16. The conical portion 13 and its projecting projecting portion 19 are movable from said rest position.

Si maintenant un utilisateur exerce une pression de l'extérieur vers l'intérieur sur la face extérieure de la plaque 11, cette pression engendre un déplacement de la plaque 11 et de la partie conique 13 vers la carte électronique 6 et vers une position d'actionnement, par exemple sur une faible course, en déformant élastiquement la branche de liaison 17 et les pattes de soutien 18 et/ou de leurs jonctions avec la partie annulaire 15 et/ou la partie de fixation 16 à l'encontre de leur élasticité. Ce faisant, la portion en saillie 19 vient actionner le commutateur électrique 9. La course de la partie conique 13 peut être limitée par le fait que le sommet 13a de la partie conique 13 vient en appui sur la carte électronique 6.If now a user exerts a pressure from outside to inside on the outer face of the plate 11, this pressure causes a displacement of the plate 11 and the conical part 13 towards the electronic card 6 and towards a position of actuation, for example on a short stroke, elastically deforming the connecting leg 17 and the support lugs 18 and / or their junctions with the annular portion 15 and / or the fixing portion 16 against their elasticity. In doing so, the projecting portion 19 actuates the electric switch 9. The stroke of the conical portion 13 may be limited by the fact that the top 13a of the conical portion 13 bears on the electronic card 6.

Quand l'utilisateur relâche la pression sur la plaque 11, cette dernière et la partie conique 13 reviennent à leur position de repos décrite plus haut grâce à l'élasticité des parties déformées de l'organe intermédiaire 12.When the user releases the pressure on the plate 11, the latter and the conical portion 13 return to their rest position described above thanks to the elasticity of the deformed parts of the intermediate member 12.

La paroi frontale 7, la plaque 11 et l'organe intermédiaire 12 sont agencés par conjugaisons de formes de telle sorte que la plaque soit maintenue et guidée entre ladite position de repos et ladite position d'actionnement.The front wall 7, the plate 11 and the intermediate member 12 are arranged by conjugations of shapes such that the plate is held and guided between said rest position and said actuating position.

La carte électronique 6 est munie en outre d'un capteur de lumière 23 situé du côté de la partie conique 13 de l'organe intermédiaire 12 et à distance de l'élément lumineux 8 et du commutateur électrique 9. La partie conique 13 présente une partie en saillie 24 au travers de laquelle est aménagé un trou traversant 25 situé au-dessus du capteur de lumière 23, de telle sorte que le capteur de lumière 23 est sensible à la lumière extérieure traversant la plaque 11.The electronic card 6 is further provided with a light sensor 23 located on the side of the conical portion 13 of the intermediate member 12 and remote from the light element 8 and the electrical switch 9. The conical portion 13 has a projecting portion 24 through which a through-hole 25 is arranged above the light sensor 23, so that the light sensor 23 is sensitive to the external light passing through the plate 11.

I1 résulte de ce qui précède que la lumière émise par l'élément lumineux 8 se diffuse dans la partie conique 13 vers la plaque 11, directement et par réflexion sur la surface intérieure réfléchissante de la partie conique 13, traverse la plaque 11 et se diffuse à l'extérieur à l'avant du boîtier 2. La lumière émise peut alors éclairer l'espace environnant le boîtier 2.It follows from the above that the light emitted by the light element 8 is diffused in the conical part 13 towards the plate 11, directly and by reflection on the reflective inner surface of the conical part 13, passes through the plate 11 and diffuses on the outside at the front of the housing 2. The emitted light can then illuminate the space surrounding the housing 2.

L'activation du commutateur électrique 5 par un utilisateur peut avoir pour objet de programmer ou paramétrer la carte électronique 6 et/ou d'effectuer des tests de cette dernière et/ou d'activer l'élément lumineux 8. Le boîtier 2 peut être équipé de voyants lumineux de signalisation.The activation of the electrical switch 5 by a user may have for object to program or parameterize the electronic card 6 and / or to test the latter and / or to activate the light element 8. The casing 2 may be equipped with indicator lights.

Selon une application particulière, le dispositif électronique 1 peut être équipé d'un organe de détection 25 disposé par exemple au-dessous de la carte électronique et relié à cette dernière.According to a particular application, the electronic device 1 may be equipped with a detection member 25 disposed for example below the electronic card and connected thereto.

Le boîtier 2 peut être installé au plafond d'un espace à surveiller, par exemple par l'intermédiaire d'un socle de fixation, la paroi frontale 7 étant orientée vers le bas et l'embase 3 présentant des passages d'aération 26 pour que l'air ambiant atteigne l'organe de détection 25.The housing 2 can be installed on the ceiling of a space to be monitored, for example by means of a mounting base, the front wall 7 being oriented downwards and the base 3 having ventilation passages 26 for that the ambient air reaches the detection member 25.

L'organe de détection 25 peut être un détecteur de fumée, un détecteur de gaz dangereux, un détecteur de rayonnements dangereux, un détecteur de chaleur, de froid, d'humidité, d'eau (inondation) ou un détecteur de coupure de courant, un détecteur de séisme, ou un détecteur de présence. Le dispositif électronique 1 pourrait être équipé de plusieurs organes de détection différents.The detection member 25 may be a smoke detector, a dangerous gas detector, a hazardous radiation detector, a heat, cold, humidity, water (flood) detector or a power failure detector. , an earthquake detector, or a presence detector. The electronic device 1 could be equipped with several different detection members.

La carte électronique 6 peut être programmée pour activer l'élément lumineux 8 sous certaines conditions.The electronic card 6 can be programmed to activate the light element 8 under certain conditions.

Par exemple, si la carte électronique 6 reçoit un signal de détection issu de l'organe de détection 25 signifiant la présence d'un danger, la carte électronique 6 engendre non seulement l'émission d'un signal d'avertissement sonore et/ou d'un signal, par exemple radio, vers un autre dispositif d'avertissement, mais également, peut activer l'élément lumineux 8 pour que l'espace situé au-dessous du boîtier 2 soit éclairé au bénéfice des personnes se trouvant dans l'espace surveillé. Selon un autre exemple, la défaillance des piles d'alimentation de la carte électronique 6 peut être signalée en activant l'élément lumineux 8.For example, if the electronic card 6 receives a detection signal from the detection member 25 signifying the presence of a danger, the electronic card 6 generates not only the emission of an audible warning signal and / or a signal, for example radio, to another warning device, but also, can activate the light element 8 so that the space below the housing 2 is illuminated for the benefit of people in the monitored space. In another example, the failure of the power supply batteries of the electronic card 6 can be signaled by activating the light element 8.

Le dispositif électronique 1 peut présenter notamment les variantes de réalisation suivantes.The electronic device 1 may present in particular the following variants.

Les pattes de soutien 18 pourraient être inexistantes.The support legs 18 could be nonexistent.

Pour suspendre élastiquement la partie conique 13 de l'organe intermédiaire 12, la branche de liaison 17 et la partie de fixation 16 pourraient être remplacées par des pattes de soutien équivalentes aux pattes de soutien 18.To elastically suspend the conical portion 13 of the intermediate member 12, the connecting leg 17 and the fixing portion 16 could be replaced by support tabs equivalent to the support legs 18.

L'organe intermédiaire 12 pourrait présenter une partie complémentaire accessible de l'extérieur, s'étendant par exemple latéralement à la plaque 11 dans l'épaisseur de la paroi frontale 7, de telle sorte qu'un utilisateur pourrait exercer une pression sur cette partie complémentaire pour déformer élastiquement l'organe intermédiaire 12 et activer le commutateur électrique 9.The intermediate member 12 could have a complementary part accessible from the outside, extending for example laterally to the plate 11 in the thickness of the front wall 7, so that a user could exert pressure on this part. complementary to elastically deform the intermediate member 12 and activate the electrical switch 9.

La portion en saillie 19 pourrait être aménagée en un autre endroit de l'organe intermédiaire 12, par exemple sur la branche de liaison 17, le commutateur électrique 9 étant placé en conséquence sur la carte électronique 6.The protruding portion 19 could be arranged at another location of the intermediate member 12, for example on the connecting branch 17, the electrical switch 9 being placed accordingly on the electronic card 6.
