Definitions
- the present invention relates to a domestic appliance of the type in which the control and operating members are arranged in correspondence with a front panel placed on the front surface of the appliance.
- these control members in the form of knobs, buttons, handles and the like, protrude permanently from the front panel by a sufficient measure to be able to be properly grasped and maneuvered.
- this projecting position of the control members has drawbacks of both an aesthetic and technical nature. Aesthetically, it is obvious that the device, when it is not in use, would look more pleasant if it did not have protruding control members.
- the projecting control elements are subject to involuntary shocks or pressures, which are particularly easy during cleaning operations of the premises and which can either damage the control elements themselves or the mechanisms to which they are connected, or cause undesirable setting. in operation of the device with the consequent drawbacks and dangers, such as gas leaks, uncontrolled temperature rises etc.
- the object of the present invention is to realize a domestic appliance of the type indicated in the preamble, which has two conditions, one of rest, in which the control members do not protrude from the front panel, and the 'other operative, in which the control members protrude properly for their operation; and in which apparatus the passage from one to the other of the conditions simultaneously interests all the control members, without the need for any special kinematic coupling between the control bodies and the mechanisms they control.
- control and operating members are arranged in a fixed position and terminate previously substantially in correspondence with the plane which previously limits the size of the apparatus, and that the front panel is mounted movable between a rest position, in which it is disposed with its front surface substantially in correspondence of said limit plane, and an operative position, in which said panel is set back relative to said limit plane and to the operating members, of a sufficient measure to allow seizure and actuation of said organs.
- each control member which is moved between a rest position and an operative position
- this entails, on the one hand, the advantage that with a single operation (the movement of the panel) the apparatus is worn in the desired condition, with effect on all of its control and operating members, and on the other hand the advantage that the element which must be moved has no relation to the mechanisms of the device and therefore does not require any complex transmission connection. It follows, not only that the maneuver is more convenient, but also that the construction is substantially simplified with the consequent reduction of the costs and the probability of damage.
- the front panel is preferably pushed towards its rest position by one or more springs, and it can be brought into its operative position by pushing it against the action of these springs.
- a hanging device is preferably provided which retains the panel in its operative position. tive retracted when it is pushed into this position and until the execution of a successive operation to remove the action of said attachment device.
- This attachment device is preferably a two-stage controlled retaining device, so that a first pressure exerted on the panel makes it move back and remain in the operative position, and a second pressure on the panel releases it and allows the springs return it to the rest position.
- the movable front panel is advantageously connected to the fixed structure of the device by a kinematic system which limits the freedom of movement of the panel by allowing it to move only while remaining parallel to itself.
- a kinematic system which limits the freedom of movement of the panel by allowing it to move only while remaining parallel to itself.
- Said kinematic system preferably comprises two levers pivoted on a central point of the fixed structure, joined to the movable front panel at points distant from each other, and coupled together so that they can only make symmetrical oscillations .
- an element joined to the movable panel to be disposed on the path of the control element of an electric switch, so that the latter is switched from one to the other of its positions depending on whether the front panel is in rest or operating position.
- the switch can be used to indicate to the user an inappropriate position of the panel, or also to directly perform an action capable of preventing inconvenience caused by this inappropriate position; this action can, for example, happen to make impossible the operation of the device when the front panel is in the rest position.
- the domestic appliance partially represented in FIG. 1 is a domestic gas oven, taken as an example of application of the invention, but it should be understood that the invention is also applicable to other domestic appliances such as kitchens , stoves and the like, whether gas, electric or mixed, or even other household appliances such as washing machines, dishes, etc.
- the oven shown has a fixed structure 1 which ends previously with a cornice 2 which, in this case, defines the anterior limit plane of the appliance.
- a cornice 2 which, in this case, defines the anterior limit plane of the appliance.
- the door 3 of the cooking chamber Inside the cornice 2, in the lower part of the appliance, there is the door 3 of the cooking chamber, the anterior surface of which is, in this case, substantially in the same plane which limits the cornice 2.
- the operating handle 4 and ventilation openings 5 below which there is a glass window 6 for the observation of the cooking chamber when the door is closed.
- the upper part of the front face of the device is occupied, in this case, by a front panel 7 crossed by the control and operating members, such as two buttons 8 connected to the taps 9, located behind, for controlling the gas burners supply, and two small buttons for controlling timers, the condition of which is visible through a window 11 in panel 7.
- the control and operating members such as two buttons 8 connected to the taps 9, located behind, for controlling the gas burners supply, and two small buttons for controlling timers, the condition of which is visible through a window 11 in panel 7.
- the control members and re manoeu- v namely, in this case, the buttons 8 and the handle 4 are mounted so that their bulk ends substantially on the same plane which limits previously congestion general of the device, and the front panel 7 is mounted mobile, between an external rest position (FIGS. 2, 4 and 6) in which also the panel 7 corresponds substantially to said limit plane, and an internal operative position (FIGS. 3, 5 and 7) in which the panel a is moved back with respect to said limit plane (defined, in this case, by the cornice 2) enough so that the handle 4 and the buttons 8 can be easily and surely gripped and maneuvered (FIG. 3) .
- the front panel 7 is guided by its own fixed cornice 12 and tabs 13 which project posteriorly relative to the panel 7 and are supported by stirrups 16 joined to the fixed structure 1.
- the tabs 13 have upper relief relief 14 and a hooking tooth 15-to cooperate with hooking devices capable of retaining them in the operative position; springs 17 are arranged between the fixed structure 1 and the movable panel 7 to push the latter towards its rest position.
- the front panel 7 is provided with hooking devices and springs at each end, but obviously one of said components or both could be arranged, on the contrary, in the center of the mobile front panel 7.
- Each attachment device ( Figures 4 to 10 ) comprises a plate 18 hooked by a tooth 19 to the fixed bracket 16 so that it can oscillate both horizontally and vertically, and it is recalled by an oblique spring 25 which thus exerts the return action either for horizontal oscillations than for vertical oscillations.
- the plate 18 has a window 20, partially occupied by an oblique tongue 21 and open towards one side of the plate through an oblique passage defined by opposite ramps 22 and 23, the latter forming the end of a curved surface inclined 24 which limits the plate 18 towards the panel 7.
- this hooking device is as follows: in the rest position (figures from 4 to 6) the plate 18 is supported on the relief 14 of the tongue 13 and takes no action; the front panel 7 is retained in its external position by the thrust of the springs 17. By exerting pressure on the panel 7, the springs 17 are compressed and the front panel 7 moves inward. The tooth 15 of the tongue 13 then comes into contact with the inclined curved surface 24 of the plate 18 and causes the plate to oscillate horizontally against the action of the spring 25 until the tooth 15 can exceed the end 23 of the plate and it will lean against the ramp 22 ( Figure 8).
- the fixed structure 1 of the device carries a support 16 to which are fixed two parallel pins 26 on each of which is pivoted a lever 27.
- the two levers 27 have toothed sectors 28 meshed between them, so that the levers can only swing symmetrically.
- return springs 17 On the pins 26 are inserted return springs 17 arranged so that they push the levers 27 towards the outside of the fixed structure 1 of the device.
- the free ends of the levers 27 carry pivots 29 engaged in buttonhole holes 31 of stirrups 30 mounted on the rear surface of the front panel 7.
- the arrangement described supports the movable panel 7 and normally maintains it in its rest position according to the Figures 11 and 13, position which can be defined by the cooperation of the pivots 29 with the button holes 31, or by appropriate stops.
- one of the levers 27 (or any other part united to the front panel 7) has a tooth 15 which cooperates with a hooking device 18-25 which can be the same as described in connection with the first embodiment.
- This guide means can advantageously be produced by a simple rod 13 presented by the front panel 7 and which passes through a corresponding hole formed in the fixed structure 1.
- One of the levers 27 (or any other part joined to the front panel 7) is arranged so that, during the movement of the panel towards the operative position or towards the rest position, this lever acts on the control element 33 of an electrical switch or switch 32 mounted on the fixed structure 1 of the device.
- This switch can be inserted so that it directly or indirectly controls the operation of the device, so that it allows operation only when the front panel 7 is in the operative position.
- the switch or switch 32 can be used to activate any other suitable function, or else to order appropriate signaling intended to warn the user of the situation which has occurred and of the possible drawbacks which may derive therefrom.
- a locking device can be provided which retains the panel 7 in the operative position, or prevents its return to the rest position, as long as the device is in operation.
- the two-stage attachment device which has just been described is particularly suitable for the intended application but, of course, other known or special attachment devices can also be used to retain the movable front panel 7 in its operative position and, in particular, it is possible to use either hooking devices controlled in two stages, or simple hooks capable of tripping in the retaining position when the panel 7 is pushed into the operative position and provided with a neutralization which can be actuated by a small lever, a pusher or other similar element, to release the front panel when it has to return to its rest position.
- FIG. 1 illustrates the most frequent case where the front panel 7 is arranged horizontally along the upper edge of the device, this panel can also be arranged horizontally along the bottom edge of the device, or else centrally between two parts. separate and superimposed on the device, or it can be arranged vertically, along the left or right edge of the device, or centrally between two separate parts located side by side of the device.

Description
La présente invention se réfère à un appareil domestique du type dans lequel les organes de commande et de manoeuvre sont disposés en correspondance d'un panneau frontal placé sur la surface antérieure de l'appareil.The present invention relates to a domestic appliance of the type in which the control and operating members are arranged in correspondence with a front panel placed on the front surface of the appliance.
Dans les constructions habituelles, ces organes de commande, sous forme de pommeaux, boutons, poignées et similaires, font saillie en permanence du panneau frontal d'une mesure suffisante pour pouvoir être convenablement saisis et manoeuvrés. Mais cette position saillante des organes de commande présente des inconvénients de nature soit esthétique que technique. Esthétiquement, il est évident que l'appareil, quand il n'est pas en fonction, se présenterait de manière plus agréable s'il n'aurait pas des organes de commande saillants. Techniquement, les organes de commande saillants sont sujets à recevoir des chocs ou des pressions involontaires, particulièrement faciles pendant les opérations de nettoyage des locaux et qui peuvent soit endommager les organes de commande mêmes ou les mécanismes auxquels ils sont reliés, soit causer une indésirable mise en fonctionnement de l'appareil avec les inconvénients et dangers conséquents, tels que fuites de gaz, hausses incontrôlées de température etc.In usual constructions, these control members, in the form of knobs, buttons, handles and the like, protrude permanently from the front panel by a sufficient measure to be able to be properly grasped and maneuvered. However, this projecting position of the control members has drawbacks of both an aesthetic and technical nature. Aesthetically, it is obvious that the device, when it is not in use, would look more pleasant if it did not have protruding control members. Technically, the projecting control elements are subject to involuntary shocks or pressures, which are particularly easy during cleaning operations of the premises and which can either damage the control elements themselves or the mechanisms to which they are connected, or cause undesirable setting. in operation of the device with the consequent drawbacks and dangers, such as gas leaks, uncontrolled temperature rises etc.
Pour cette raison, il y a aujourd'hui. une demande d'appareils domestiques dont les organes de commande, qui doivent résulter saillants par rapport au panneau frontal quand l'appareil est en fonctionnement pour permettre une manoeuvre facile, peuvent être faits dispàraître en supprimant leur saillie par rapport au panneau, quand l'appareil ne fonctionne pas. Dans cet ordre d'idées on a réalisé des appareils dans lesquels chaque organe d.e com mande est monté mobile entre une position de repos dans laquelle il est encaissé dans le panneau et une position opérative dans laquelle il est convenablement saillant. Avec cette disposition, chaque organe de commande reste normalement encaissé et on l'extrait quand il doit être manoeuvré. Mais cela suppose un accouplement cinématique relativement complexe entre chaque organe de commande et le mécanisme auquel il est relié, et cause donc une construction complexe, coûteuse et sujette à des faciles dégâts. En outre, pour porter l'appareil de la condition de repos à la condition opérative ou vice-versa, il faut effectuer une pluralité d'actions sur les différents organes de commande.For this reason, there are today. a request for domestic appliances, the control members of which, which must protrude from the front panel when the appliance is in operation to allow easy operation, can be made to disappear by removing their projection from the panel, when the device does not work. In this order of ideas, devices have been produced in which each control member is mounted movable between a rest position in which it is housed in the panel and an operative position in which it is suitably protruding. With this arrangement, each control member remains normally collected and is extracted when it must be operated. But this supposes a relatively complex kinematic coupling between each control member and the mechanism to which it is connected, and therefore causes a complex construction, costly and subject to easy damage. In addition, to bring the device from the rest condition to the operational condition or vice versa, it is necessary to perform a plurality of actions on the different control members.
Le but de la présente invention est celui de réali ser un appareil domestique du type indiqué dans le préambule, qui présente deux conditions, l'une de repos, dans laquelle les organes de commande ne font pas saillie par rapport au panneau frontal, et l'autre opérative, dans laquelle les organes de commande font convenablement saillie pour leur manoeuvre; et dans lequel appareil le passage de l'une à l'autre des conditions intéresse simultanément tous les organes de commande, sans qu'il soit nécessaire aucun accouplement cinématique spécial entre les organes de commande et les mécanismes qu'ils contrôlent.The object of the present invention is to realize a domestic appliance of the type indicated in the preamble, which has two conditions, one of rest, in which the control members do not protrude from the front panel, and the 'other operative, in which the control members protrude properly for their operation; and in which apparatus the passage from one to the other of the conditions simultaneously interests all the control members, without the need for any special kinematic coupling between the control bodies and the mechanisms they control.
Selon l'invention, ce but est atteint par le fait que les organes de commande et manoeuvre sont disposés en position fixe et se terminent antérieurement substantiellement en correspondance du plan qui limite antérieurement l'encombrement de l'appareil, et que le panneau frontal est monté mobile entre une position de repos, dans laquelle il est disposé avec sa surface frontale substantiellement en correspondance dudit plan limite, et une position opérative, dans laquelle ledit panneau se trouve reculé par rapport audit plan limite et aux organes de manoeuvre, d'une mesure suffisante pour permettre de saisir et d'actionner lesdits organes.According to the invention, this object is achieved by the fact that the control and operating members are arranged in a fixed position and terminate previously substantially in correspondence with the plane which previously limits the size of the apparatus, and that the front panel is mounted movable between a rest position, in which it is disposed with its front surface substantially in correspondence of said limit plane, and an operative position, in which said panel is set back relative to said limit plane and to the operating members, of a sufficient measure to allow seizure and actuation of said organs.
Ainsi, c'est le panneau frontal, au lieu que chaque organe de commande, qui est déplacé entre une position de repos et une position opérative, et cela entraîne, d'un côté, l'avantage qu'avec une seule opération (le déplacement du panneau) on porte l'appareil dans la condition voulue, avec effet sur tous ses organes de commande et maneuvre, et d'autre côté l'avantage que l'élément qui doit être déplacé n'a aucun rapport avec les mécanismes de l'appareil et n'exige donc aucune connexion de transmission complexe. Il s'ensuit, non seulement que la manoeuvre est plus commode, mais aussi que la construction est substantiellement simplifiée avec la conséquente réduction des coûts et des probabilités de dégâts.Thus, it is the front panel, instead of each control member, which is moved between a rest position and an operative position, and this entails, on the one hand, the advantage that with a single operation (the movement of the panel) the apparatus is worn in the desired condition, with effect on all of its control and operating members, and on the other hand the advantage that the element which must be moved has no relation to the mechanisms of the device and therefore does not require any complex transmission connection. It follows, not only that the maneuver is more convenient, but also that the construction is substantially simplified with the consequent reduction of the costs and the probability of damage.
Le panneau frontal est préférablement poussé vers sa position de repos par un ou plusieurs ressorts, et il peut être porté dans sa position opérative en le poussant contre l'action de ces ressorts.The front panel is preferably pushed towards its rest position by one or more springs, and it can be brought into its operative position by pushing it against the action of these springs.
En outre, on prévoit préférablement un dispositif d'accrochage qui retient le panneau dans sa position opérative reculée quand il est poussé dans cette position et jusqu'à l'exécution d'une opération successive pour supprimer l'action dudit dispositif d'accrochage.In addition, a hanging device is preferably provided which retains the panel in its operative position. tive retracted when it is pushed into this position and until the execution of a successive operation to remove the action of said attachment device.
Ce dispositif d'accrochage est préférablement un dispositif de retenue commandé en deux-temps, de sorte qu'une première pression exercée sur le panneau le fait reculer et rester en position opérative, et une seconde pression sur le panneau le dégage et permet que les ressorts le reportent en position de repos.This attachment device is preferably a two-stage controlled retaining device, so that a first pressure exerted on the panel makes it move back and remain in the operative position, and a second pressure on the panel releases it and allows the springs return it to the rest position.
Le panneau frontal mobile est avantageusement relié à la structure fixe de l'appareil par un système cinématique qui limite la liberté de mouvement du panneau en lui permettant de se déplacer seulement en demeurant parallèle à soi même. Ainsi, même si le panneau est sollicité asymétriquement ou s'il subit des résistances ac- cidentales asymétriques, son déplacement correct de la position de- repos à la position opérative ou vice-versa est également assuré sans qu'il puisse se disposer de travers ou se bloquer.The movable front panel is advantageously connected to the fixed structure of the device by a kinematic system which limits the freedom of movement of the panel by allowing it to move only while remaining parallel to itself. Thus, even if the panel is biased asymmetrically or if it undergoes asymmetrical accidental resistances, its correct displacement from the rest position to the operative position or vice versa is also ensured without it being able to have a bias or hang.
Ledit système cinématique comprend préférablement deux leviers pivotés sur un point central de la structure fixe, joints au panneau frontal mobile en des points éloignés l'un de l'autre, et couplés entre eux de manière qu'il ne peuvent faire que des oscillations symétriques.Said kinematic system preferably comprises two levers pivoted on a central point of the fixed structure, joined to the movable front panel at points distant from each other, and coupled together so that they can only make symmetrical oscillations .
Il est enfin avantageux qu'un élément joint au panneau mobile soit disposé sur la trajectoire de l'élément de commande d'un interrupteur électrique, de manière que àe dernier soit commuté de l'une à l'autre de ses positions selon que le panneau frontal se trouve en position de repos ou en position opérative. Grâce à cette disposition, l' interrupteur peut être utilisé pour indiquer à l'usager une position inopportune du panneau, ou bien aussi pour effectuer directement une action capable de prévenir des inconvénients causés par cette position inopportune; cette action peut, par exemple, arriver à rendre impossible le fonctionnement de l'appareil quand le panneau frontal est en position de repos.Finally, it is advantageous for an element joined to the movable panel to be disposed on the path of the control element of an electric switch, so that the latter is switched from one to the other of its positions depending on whether the front panel is in rest or operating position. Thanks to this arrangement, the switch can be used to indicate to the user an inappropriate position of the panel, or also to directly perform an action capable of preventing inconvenience caused by this inappropriate position; this action can, for example, happen to make impossible the operation of the device when the front panel is in the rest position.
Les susdites et d'autres caractéristiques et avantages de l'objet de l'invention seront rendus plus clairs par la suivante description de deux formes de réalisation, constituant des exemples non limitatifs, schématiquement représentées dans les dessins annexés, dans lesquels :

L'appareil domestique partiellement représenté dans la figure 1 est un four domestique à gaz, pris comme exemple d'application de l'invention, mais l'on doit comprendre que l'invention est également applicable à d'autres appareils domestiques tels que cuisines, réchauds et similaires, soit a gaz qu'électriques ou mixtes, ou même à d'autres appareils domestiques tels que les machines à laver le linge, la vaisselle etc.The domestic appliance partially represented in FIG. 1 is a domestic gas oven, taken as an example of application of the invention, but it should be understood that the invention is also applicable to other domestic appliances such as kitchens , stoves and the like, whether gas, electric or mixed, or even other household appliances such as washing machines, dishes, etc.
Le four représenté présente une structure fixe 1 qui se termine antérieurement par une corniche 2 laquelle, dans ce cas, définit le plan limite antérieur de l' appareil. A l'intérieur de la corniche 2, dans la partie inférieure de l'appareil se trouve la portière 3 de la chambre de cuisson, dont la surface antérieure est, dans ce cas, substantiellement dans le même plan qui limite la corniche 2. Dans la partie supérieure de la portière 3 sont visibles la poignée de manoeuvre 4 et des ouvertures d'aération 5 au dessous desquelles il y a une fenêtre vitrée 6 pour l'observation de la chambre de cuisson quand la portière est fermée.The oven shown has a fixed structure 1 which ends previously with a
La partie supérieure de la face antérieure de l'appareil est occupée, dans ce cas, par un panneau frontal 7 traversé par les organes de commandes et manoeuvre, tels que deux boutons 8 reliés aux robinets 9, situés derrière, de contrôle de l'alimentation des brûleurs à gaz, et deux petits boutons pour la commande de temporisateurs, dont la condition est visible à travers une fenêtre 11 du panneau 7.The upper part of the front face of the device is occupied, in this case, by a
Selon l'invention, les organes de commande et manoeu- vre, à savoir, dans ce cas, les boutons 8 et la poignée 4, sont montés de manière que leur encombrement se termine substantiellement sur le même plan qui limite antérieurement l'encombrement général de l'appareil, et le panneau frontal 7 est monté mobile, entre une position extérieure de repos (figures 2, 4 et 6) dans laquelle aussi le panneau 7 correspond substantiellement audit plan limite, et une position intérieure opérative (figures 3, 5 et 7) dans laquelle le panneau a est reculé par rapport audit plan limite (défini, dans ce cas,par la corniche 2) suffisamment pour que la poignée 4 et les boutons 8 puissent être facilement et sûrement saisis et manoeuvrés (figure 3).According to the invention, the control members and re manoeu- v, namely, in this case, the
Dans le déplacement entre ces deux positions, le panneau frontal 7 est guidé par une propre corniche fixe 12 et des languettes 13 qui font saillie postérieurement par rapport au panneau 7 et sont soutenues par des étriers 16 joints à la structure fixe 1. Les languettes 13 présentent supérieurement un relief d'appui 14 et une dent d' accrochage 15-pour coopérer avec des dispositifs d'accrochage capables de les retenir dans la position opérative ; des ressorts 17 sont disposés entre la structure fixe 1 et le panneau mobile 7 pour pousser ce dernier vers sa position de repos. Dans l'exemple représenté, le panneau frontal 7 est pourvu de dispositifs d'accrochage et de ressorts à chaque extrémité, mais évidemment un desdits composants ou tous les deux pourraient être disposés, au contraire, au centre du panneau frontal mobile 7.In the movement between these two positions, the
Chaque dispositif d'accrochage (figures de 4 à 10) comprend une plaquette 18 accrochée par une dent 19 à l'étrier fixe 16 de manière qu'elle puisse osciller soit horizontalement que verticalement, et elle est rappelée par un ressort oblique 25 qui exerce ainsi l'action de rappel soit pour les oscillations horizontales que pour les oscillations verticales. La plaquette 18 présente une fenêtre 20, partiellement occupée par une languette oblique 21 et ouverte vers un côté de la plaquette à travers d'un passage oblique défini par des rampes opposées 22 et 23, cette dernière formant l'extrémité d'une surface curve inclinée 24 qui limite la plaquette 18 vers le panneau 7. Le fonctionnement de ce dispositif d'accrochage est le suivant : dans la position de repos (figures de 4 à 6) la plaquette 18 s'appuie sur le relief 14 de la languette 13 et n'exerce aucune action; le panneau frontal 7 est retenu dans sa position extérieure par la poussée des ressorts 17. En exerçant une pression sur le panneau 7, les ressorts 17 sont comprimés et le panneau frontal 7 se déplace vers l'intérieur. La dent 15 de la languette 13 arrive alors à contact avec la surface curve inclinée 24 de la plaquette 18 et fait osciller la plaquette horizontalement contre l'action du ressort 25 jusqu'à ce que la dent 15 peut surpasser l'extrémité 23 de la plaquette et elle va s'appuyer contre la rampe 22 (figure 8). Quand la pression sur le panneau 7 cesse, l'action combinée des ressorts 17 et 25 agit de manière que la dent 15 passe entre les rampes 22 et 23 et s'appuie latéralement, dans la fenêtre 20 de la plaquette 18, contre la languette inclinée 21 (figures 5 et 7). Il est évident que, dans cette condition, le panneau frontal 7 est retenu en position reculée par l'engagement de la dent 15 dans la fenêtre 20. En exerçant ensuite une nouvelle pression sur le panneau 7, la dent 15 est poussée dans la fenêtre 20 jusqu'au delà de la languette 21, et le ressort 25 rappelle la plaquette 18 de sa position précédente déplacée horizontalement (figure 9). Par conséquence, lors que la pression sur le panneau cesse, la dent 15 s'engage sous la languette inclinée 21 et elle fait osciller vers le haut la plaquette 18 (figure 10), de sorte que la dent se dégage de la fenêtre 20 et permet au panneau frontal 7 de retourner dans sa position de repos représentée dans les figures 4 et 6.Each attachment device (Figures 4 to 10 ) comprises a
Dans la seconde forme de réalisation, la structure fixe 1 de l'appareil porte un support 16 auquel sont fixés deux tourillons parallèles 26 sur chacun desquels est pivoté un levier 27. Les deux leviers 27 ont des secteurs dentés 28 engrenés entre eux, de sorte que les leviers ne peuvent osciller que symétriquement. Sur les tourillons 26 sont insérés des ressorts de rappel 17 disposés de manière qu'ils poussent les leviers 27 vers l'extérieur de la structure fixe 1 de l'appareil. Les extrémités libres des leviers 27 portent des pivots 29 engagés dans des trous à boutonnière 31 d' étriers 30 montés sur la surface arrière du panneau frontal 7. La disposition décrite supporte le panneau mobile 7 et le maintient normalement dans sa position de repos selon les figures 11 et 13, position qui peut être définie par la coopération des pivots 29 avec les boutornières 31, ou bien par des arrêts appropriés. Si l'on applique une pression au panneau 7, celui-ci peut rentrer vers sa position opérative selon les figures 12 et 14, contre l'action des ressorts 17, pendant que les pivots 29 des leviers 27 glissent dans les boutonnières 31. Puisque les leviers 27 sont réciproquement engrenés en 28, ce déplacement du panneau frontal 7 peut s'effectuer seulement par translation pa- rallèle, quel que soit le point du panneau où la pression est appliquée, et quelle que soit la distribution des résistance au mouvement.In the second embodiment, the fixed structure 1 of the device carries a
Pour retenir le panneau mobile 7 dans la position opérative où il a été porté, un des leviers 27 (ou bien une autre pièce quelconque unie au panneau frontal 7) présente une dent 15 qui coopère avec un dispositif d' accrochage 18-25 qui peut être le même qu'on a décrit à propos de la première forme de réalisation.To retain the
Puisque la disposition décrite de support du panneau frontal 7, comprenant des trous à boutonnière, ne peut pas assurer le centrage du panneau selon sa dimension longitudinale quand le panneau est reculé, il est opportun de disposer d'un moyen de guidage dudit panneau mobile. Ce moyen de guidage peut être avantageusement réalisé par une simple tige 13 présentée par le panneau frontal 7 et qui passe à travers d'un trou correspondant formé dans la structure fixe 1.Since the described arrangement for supporting the
Un des leviers 27 (ou une autre pièce quelconque unie au panneau frontal 7) est disposé de manière que, pendant le déplacement du panneau vers la position opérative ou vers la position de repos, ce levier agit sur l'élément de commande 33 d'un interrupteur ou commutateur électrique 32 monté sur la structure fixe 1 de l'appareil. Cet interrupteur peut être inséré de manière qu'il contrôle directement ou indirectement le fonctionnement de l'appareil, de sorte qu'il consent le fonctionnement seulement quand le panneau frontal 7 se trouve en position opérative. Alternativement, l'interrupteur ou commutateur 32 peut être utilisé pour activer une autre fonction quelconque opportune, ou bien pour commander une signalisation appropriée destinée à avertir l'usager de la situation qui s'est vérifiée et des inconvénients possibles qui peuvent en dériver.One of the levers 27 (or any other part joined to the front panel 7) is arranged so that, during the movement of the panel towards the operative position or towards the rest position, this lever acts on the
Alternativement ou en plus de l'interrupteur 32 sensible à la position du panneau mobile 7, on peut prévoir un dispositif de blocage qui retient le panneau 7 dans la position opérative, ou en empêche le retour en position de repos, tant que l'appareil est en fonctionnement.Alternatively or in addition to the
Le dispositif d'accrochage.commandé en deux temps qui vient d'être décrit est particulièrement approprié pour l'application prévue mais, bien entendu, d'autres dispositifs d'accrochage connus ou spéciaux peuvent être aussi employés pour retenir le panneau frontal mobile 7 dans sa position opérative et, particulièrement, on peut utiliser soit des dispositifs d'accrochage commandés en deux temps, soit des simples crochets capables de déclencher en position de retenue lors que le panneau 7 est poussé en position opérative et munis d'un organe de neutralisation qui peut être actionné par un petit levier, un poussoir ou autre élément similaire, pour libérer le panneau frontal alors qu'il doit returner dans sa position de repos.The two-stage attachment device which has just been described is particularly suitable for the intended application but, of course, other known or special attachment devices can also be used to retain the movable
Quoique la figure 1 illustre le cas le plus fréquent où le panneau frontal 7 est disposé horizontalement lelong du bord supérieur de l'appareil, ce panneau peut être aussi disposé horizontalement lelong du bord inférieur de l'appareil, .ou bien centralement entre deux parties distinctes et superposées de l'appareil, ou encore il peut être disposé verticalement, lelong du bord gauche ou droit de l'appareil, ou centralement entre deux parties distinctes situées côte à côte de l'appareil.Although FIG. 1 illustrates the most frequent case where the
