Description

L'invention a pour objet un meuble muni d'une porte à charnières, et plus particulièrement un appareil de réfrigération comprenant un circuit électrique d'utilisation placé dans sa contre-porte, ce qui est le cas, par exemple, d'un réfrigérateur ou d'un réfrigérateur-congélateur comportant un compartiment conditionné pour la conservation du beurre à température déterminée.The subject of the invention is a piece of furniture provided with a hinged door, and more particularly a refrigeration appliance comprising an electrical circuit for use placed in its door-panel, which is the case, for example, with a refrigerator. or a fridge-freezer with a compartment conditioned for storing butter at a certain temperature.

Lorsqu'il s'agit d'alimenter électriquement un circuit d'utilisation placé dans un réfrigérateur ou dans sa contre-porte, comme c'est le cas pour l'alimentation du circuit de contrôle de la température du compartiment à beurre par exemple, il est connu de faire passer dans l'épaisseur de la porte le fils électriques raccordant le bloc d'alimentation fixé sur le chassis de l'appareil à ce circuit d'utilisation. Cependant, on peut avoir besoin, pour diverses raisons, notamment pour changer de côté l'articulation de la porte, de démonter cette porte. Cette opération présente alors des difficultés en raison de la présence du raccordement électrique qui empêche une reversabilité aisée de la porte, c'est-à-dire l'ouverture droite ou gauche de celle-ci, et le maintien des normes imposées de sécurité électrique.When it is a question of electrically supplying a circuit of use placed in a refrigerator or against its door, as it is the case for the supply of the circuit of control of the temperature of the butter compartment for example, it is known to pass through the thickness of the door the electrical wires connecting the power supply unit fixed on the chassis of the device to this circuit of use. However, there may be a need, for various reasons, in particular to change the door hinge side, to dismantle this door. This operation then presents difficulties due to the presence of the electrical connection which prevents easy reversibility of the door, that is to say the right or left opening thereof, and the maintenance of the imposed electrical safety standards. .

La présente invention permet de remédier à cet inconvénient.The present invention overcomes this drawback.

Une grille 1 de protection est fixée sur le bandeau inférieur 19 du réfrigérateur F, et recouvre entièrement les fils f11, f21 de liaison.A cover cap 200 can be fitted onto the support element 2 as shown in FIG. 3. A protective grid 1 is fixed to the lower strip 19 of the refrigerator F, and completely covers the connecting wires f 11 , f 21 .

Le raccord R1 électrique suivant l'invention, décrit de façon détaillée dans ce qui suit, est disposé à la partie inférieure du réfrigérateur F1.The electrical connection R 1 according to the invention, described in detail below, is arranged at the bottom of the refrigerator F 1 .

Ce raccord R1 électrique comprend, d'une part, un élément support 2 qui peut être fixé, de façon amovible au moyen de vis v2 par exemple sur le réfrigérateur F1 (figure 2). Cet élément support 2 est formé d'un socle 5 en matériau électriquement isolant portant, comme le montre de façon plus détaillée les figures 4 et 5, deux cylindres 3, 4 de révolution, coaxiaux, également en matériau électriquement isolant. Le socle 5 et les cylindres 3, 4 peuvent être monobloc, obtenus directement par moulage par exemple. Les cylindres 3, 4 délimitent respectivement un puits 6 central, cylindrique, et une gorge 7 annulaire, concentrique, au fond desquels sont fixés respectivement les contacts a1, b1 métalliques, élastiques.This electrical connection R 1 comprises, on the one hand, a support element 2 which can be fixed, removably by means of screws v 2 for example on the refrigerator F 1 (FIG. 2). This support element 2 is formed of a base 5 made of electrically insulating material carrying, as shown in more detail in Figures 4 and 5, two cylinders 3, 4 of revolution, coaxial, also made of electrically insulating material. The base 5 and the cylinders 3, 4 can be in one piece, obtained directly by molding for example. The cylinders 3, 4 respectively define a central well 6, cylindrical, and an annular groove 7, concentric, at the bottom of which are fixed respectively the contacts a 1 , b 1 metallic, elastic.

Deux trous 8, 9 (figure 4) prévus pour le passage des vis v2 de fixation, permettent la fixation amovible de l'élément support 2 sur le bandeau inférieur 19 du réfrigérateur F1, cet élément support 2 étant muni, dans l'exemple de réalisation montré en figure 4 de deux pions de centrage 81, 91.Two holes 8, 9 (FIG. 4) provided for the passage of the fixing screws v 2 , allow the removable fixing of the support element 2 on the lower strip 19 of the refrigerator F 1 , this support element 2 being provided, in the exemplary embodiment shown in FIG. 4 of two centering pins 81, 91.

Des fils de liaison f11, f21 issus du bloc 20 d'alimentation peuvent être connectés sur l'élément support 2, comme le montre la coupe transversale de l'élément support 2 en figure 6.Connection wires f 11 , f 21 from the power supply unit 20 can be connected to the support element 2, as shown in the cross section of the support element 2 in FIG. 6.

Un pion 21, en matériau électriquement isolant, assure le bon isolement électrique des fils de liaison f11, f21, respectivement soudés sur des cosses 22, 23 dont une extrémité traverse le socle 5 pour former des contacts a1, b1 métalliques, élastiques. Seul le contact a1 est en fait visible sur la coupe longitudinale de l'élément support 2 de la figure 5.A pin 21, made of electrically insulating material, ensures good electrical insulation of the connecting wires f 11 , f 21 , respectively welded on lugs 22, 23 one end of which crosses the base 5 to form contacts a 1 , b 1 metallic, elastic. Only the contact a 1 is in fact visible on the longitudinal section of the support element 2 in FIG. 5.

Le raccord R1 électrique comprend, d'autre part, un élément pivotant 10 prévu pour être au moyen de vis v1 sur la partie inférieure de la porte P, comme montré sur la figure 2. Cet élément pivotant 10, destiné à venir s'adapter sur l'élément support 2, est montré, en coupe longitudinale, en figure 7.The electrical connection R 1 comprises, on the other hand, a pivoting element 10 intended to be by means of screws v 1 on the lower part of the door P, as shown in FIG. 2. This pivoting element 10, intended to come s 'adapter on the support element 2, is shown, in longitudinal section, in Figure 7.

Dans cet exemple de réalisation, l'élément pivotant 10 comprend un socle 11 en matériau électriquement isolant muni d'un trou 14 de passage de la vis v, de fixation. Ce socle 11 porte deux cylindres 12, 13 métalliques de révolution, coaxiaux, sur lesquels sont connectés respectivement des fils de liaison f12, f22 (seul le fil f12 est visible sur la figure 7) prévus pour être reliés, par ailleurs, au circuit U d'utilisation (le circuit électrique de contrôle de la température d'une boîte à beurre aménagée dans la contre-porte du réfrigérateur F1 par exemple). Le cylindre 12 est un cylindre plein métallique formant un contact a2 destiné à coopérer avec le contact a1 de l'élément support 2, tandis que le cylindre 13, tubulaire, formant un contact b2, est emmanché sur un support 15 en matériau électriquement isolant de forme telle que l'élément pivotant 10 qui constitue la partie mâle du raccord R1 électrique, puisse venir s'introduire dans l'élément support 2 formant la partie femelle de ce raccord R1 électrique.In this exemplary embodiment, the pivoting element 10 comprises a base 11 made of electrically insulating material provided with a hole 14 for passing the screw v, for fixing. This base 11 carries two coaxial cylinders 12, 13 of metal of revolution, on which connection wires f 12 , f 22 are connected respectively (only the wire f 12 is visible in FIG. 7) provided to be connected, moreover, to the circuit U of use (the electrical circuit for controlling the temperature of a butter box fitted in the counter door of the refrigerator F 1 for example). The cylinder 12 is a solid metal cylinder forming a contact a 2 intended to cooperate with the contact a 1 of the support element 2, while the tubular cylinder 13, forming a contact b 2 , is fitted on a support 15 made of material electrically insulating in shape such that the pivoting element 10 which constitutes the male part of the electrical connection R 1 can be introduced into the support element 2 forming the female part of this electrical connection R 1 .

Le socle 11 de l'élément pivotant 10 comporte, autour des cylindres 12, 13, un capuchon 56 concentrique, destiné à venir coiffer les cylindres 3, 4 de l'élément support 2, l'extrémité libre du cylindre 4 venant en appui sur un épaulement 51 intérieur au capuchon 56.The base 11 of the pivoting element 10 comprises, around the cylinders 12, 13, a concentric cap 56, intended to come to cap the cylinders 3, 4 of the support element 2, the free end of the cylinder 4 coming to bear on a shoulder 51 inside the cap 56.

Le cylindre 12 ou broche centrale du raccord R1 vient se loger dans le puits 6 circulaire de l'élément support 2 (figure 5) tandis que le cylindre 13 sont l'extrémité 16 est rabattue sur le support isolant 15 vient s'introduire dans la gorge 7 annulaire, périphérique, de l'élément support 2, l'extrémité 16 formant le contact b2 électrique destiné à coopérer avec le contact b1 de l'élément support 2.The cylinder 12 or central pin of the connector R 1 is housed in the circular well 6 of the support element 2 (FIG. 5) while the cylinder 13 is the end 16 is folded over the insulating support 15 is introduced into the annular, peripheral groove 7 of the support element 2, the end 16 forming the electrical contact b 2 intended to cooperate with the contact b 1 of the support element 2.

L'élément pivotant 10 comprend à sa partie opposée aux contacts a2, b2, un téton 17 cylindrique destiné à venir s'introduire dans un orifice 18 de la porte P prévu à cet effet, comme le montre la figure 2. Le raccord R1 électrique formé de l'élément support 2 fixe et de l'élément pivotant 10 forme donc la charnière inférieure de pivotement de la porte P sur le réfrigérateur Fi.The pivoting element 10 comprises at its part opposite the contacts a 2 , b 2 , a cylindrical pin 17 intended to be introduced into an orifice 18 of the door P provided for this purpose, as shown in Figure 2. The connector R 1 electrical formed by the fixed support element 2 and the pivoting element 10 therefore forms the lower hinge for pivoting the door P on the refrigerator F i .

Dans un mode de réalisation, la porte P peut comporter à sa base deux plaquettes 34 (figure 2) munies de trous 18 et placées à droite et à gauche de la porte P. Suivant le sens d'ouverture choisi pour la porte P, l'élément support 2, et l'élément pivotant 10 qui lui est associé, seront fixés, à droite ou à gauche, respectivement sur le bandeau 19 inférieur du réfrigérateur F1 et sur la porte P, sans que les fils de liaison f11, f21, et f12, f22 aient besoin d'être déconnectés respectivement du bloc 20 d'alimentation (fils f11, f21) et du circuit U d'utilisation (fils f12, f22). Une grille 1 amovible de protection est ensuite replacée sur le bandeau 19.In one embodiment, the door P may comprise at its base two plates 34 (FIG. 2) provided with holes 18 and placed to the right and to the left of the door P. Depending on the direction of opening chosen for the door P, l the support element 2 and the pivoting element 10 associated therewith will be fixed, to the right or to the left, respectively on the lower strip 19 of the refrigerator F 1 and on the door P, without the connecting wires f 11 , f 21 , and f 12 , f 22 need to be disconnected respectively from the power supply unit 20 (wires f 11 , f 21 ) and from the circuit U of use (wires f 12 , f 22 ). A removable protective grid 1 is then replaced on the strip 19.

Afin de maintenir les fils f11 et f21 contre le bandeau 19, on peut utiliser un passe-fil 55 amovible, fixé au moyen de vis sur le bandeau 19. Ce passe-fil 55 peut être fixé soit à droite soit à gauche du bloc 20 d'alimentation.In order to hold the wires f 11 and f 21 against the strip 19, it is possible to use a removable grommet 55, fixed by means of screws on the strip 19. This grommet 55 can be fixed either to the right or to the left of the power supply 20.

Dans le cas d'un réfrigérateur F2 muni d'une porte Po à charnières du type à rotation-translation, le raccord R2 électrique permettant, à partir du bloc 20 d'alimentation, l'alimentation électrique d'un circuit U d'utilisation placé dans la contre-porte du réfrigérateur F2 comprend, comme montré en figure 8, d'une part, un premier élément 30 portant deux contacts électriques a3, b3 (figure 10) auxquels sont connectés respectivement les deux fils de liaison f,2, f22, cet élément 30, porté par un socle 32 prévu pour être fixé sur le chant inférieur de la porte Po, étant muni d'un téton 33 destiné à être introduit dans un trou 18 d'une plaquette 34 amovible (figure 8). Cet élément 30, représenté de façon plus détaillée en figure 10 et 11, est réalisé en matériau électriquement isolant. Il comprend, à l'opposé du téton 33, un capuchon 39 cylindrique ayant même axe que le téton 33 et, placés dans ce capuchon 39, deux cylindres 36 et 37, coaxiaux, métalliques, ayant même axe que le capuchon 39. Dans l'exemple de réalisation montré en figure 10, le cylindre 36 métallique est plein et forme la broche centrale (contact a3) de la partie mâle du raccord électrique R2, tandis que le cylindre 37 tubulaire formant le contact b3 est emmanché sur une pièce 38 en matériau isolant venant s'introduire dans un alésage central du capuchon 39 prévu à cet effet.In the case of a refrigerator F 2 provided with a hinged door P o of the rotation-translation type, the electrical connection R 2 allowing, from the power supply unit 20, the electrical supply of a circuit U of use placed in the counter door of the refrigerator F 2 comprises, as shown in FIG. 8, on the one hand, a first element 30 carrying two electrical contacts a 3 , b 3 (FIG. 10) to which the two wires are connected respectively of connection f, 2 , f 22 , this element 30, carried by a base 32 intended to be fixed on the lower edge of the door P o , being provided with a stud 33 intended to be introduced into a hole 18 of a removable plate 34 (Figure 8). This element 30, shown in more detail in FIGS. 10 and 11, is made of electrically insulating material. It comprises, opposite the stud 33, a cylindrical cap 39 having the same axis as the stud 33 and, placed in this cap 39, two cylinders 36 and 37, coaxial, metallic, having the same axis as the cap 39. In the exemplary embodiment shown in FIG. 10, the metallic cylinder 36 is full and forms the central pin (contact a 3 ) of the male part of the electrical connection R 2 , while the tubular cylinder 37 forming the contact b 3 is fitted onto a piece 38 of insulating material coming into a central bore of the cap 39 provided for this purpose.

Bien entendu cet ensemble de réalisation n'est pas limitatif, mais permet un montage rapide et peu coûteux de l'élément 30.Of course, this set of embodiments is not limiting, but allows rapid and inexpensive mounting of the element 30.

A cet élément 30, fixé sur la porte Po, est associé un élément 40 monté pivotant sur l'élément 30 et formant la partie femelle du raccord électrique R2, comme montré en figure 9.With this element 30, fixed on the door P o , is associated an element 40 pivotally mounted on the element 30 and forming the female part of the electrical connection R 2 , as shown in FIG. 9.

L'élément pivotant 40, montré en Goupe longitudinale en figure 12, comprend, dans cet exemple de réalisation du dispositif suivant l'invention, un socle 41 en matériau électriquement isolant portant deux cylindres 42, 43 de révolution, coaxiaux, en matériau isolant, ces cylindres 42, 43 délimitant des gorges 44, 45 au fond desquelles sont placés des contacts métalliques a4, b4 (seul le contact a4 est en fait visible sur les figures 9 et 12), destinés à coopérer avec les contacts a3, b3 de l'élément 30 respectivement.The pivoting element 40, shown in longitudinal G oupe in Figure 12, comprises, in this embodiment of the device according to the invention, a base 41 of electrically insulating material carrying two cylinders 42, 43 of revolution, coaxial, of insulating material , these cylinders 42, 43 delimiting grooves 44, 45 at the bottom of which are placed metal contacts a 4 , b 4 (only the contact a 4 is in fact visible in FIGS. 9 and 12), intended to cooperate with the contacts a 3 , b 3 of element 30 respectively.

Cet élément pivotant 40 est rendu solidaire de l'élément 30 fixé sur la porte Po au moyen, par exemple, d'une épinglette 46 en forme de U qui traverse les ouvertures 47, 48 pratiquée dans la paroi du capuchon 39, comme montré sur la coupe transversale suivant DD de la figure 11, l'élément pivotant 40, coiffé par le capuchon 39 de l'élément 30 présentant à sa périphérie une gorge 49 circulaire dans laquelle vient se loger l'épinglette 46 (figures 9, 12). L'élément pivotant 40 vient en appui sur une épaulement 50 circulaire réalisé dans l'alésage intérieur du capuchon 39.This pivoting element 40 is made integral with the element 30 fixed on the door P o by means, for example, of a pin 46 in the shape of a U which passes through the openings 47, 48 formed in the wall of the cap 39, as shown on the cross section along DD of FIG. 11, the pivoting element 40, capped by the cap 39 of the element 30 having at its periphery a circular groove 49 in which is housed the pin 46 (FIGS. 9, 12) . The pivoting element 40 bears on a circular shoulder 50 produced in the internal bore of the cap 39.

Les fils de liaison f11, f21 issus du bloc 20 d'alimentation et connectés respectivement aux contacts a4, b4 de l'élément pivotant 40 sont placés à l'intérieur d'une gaine 51 de guidage en matériau électriquement isolant et vissée sur le socle 41 de l'élément pivotant 40. Cette gaine 51 de guidage a une forme coudée et, dans l'exemple représenté en figure 8, traverse une grille 1 amovible de protection. Il est également prévu de fixer sur le chant de la porte Po une gouttière 52 de protection des fils de liaison fl2 et f 22.The connecting wires f 11 , f 21 coming from the power supply unit 20 and connected respectively to the contacts a 4 , b 4 of the pivoting element 40 are placed inside a guide sheath 51 of electrically insulating material and screwed onto the base 41 of the pivoting element 40. This guide sheath 51 has a bent shape and, in the example shown in FIG. 8, passes through a removable protective grid 1. It is also planned to fix on the edge of the door P o a gutter 52 for protecting the connecting wires f l2 and f 22 .

Pour la fixation droite ou gauche de la porte Po munie de charnières à rotation-translation, le téton 33 de l'élément 30 est introduit dans le trou 18 situé soit à droite à gauche, et le socle 32 fixé sur la porte P0 (figure 8). Le support 41 de l'élément pivotant 40 qui peut occuper deux positions à 180° l'une de l'autre à l'extrémité de la gaine 51, dans laquelle il est introduit puis fixé, sera placé convenablement dans la gaine 51, puis rendu solidaire de l'élément 30 au moyen de l'épinglette 46. Les dimensions des ouvertures de la grille 1 permettent le passage non seulement de la gaine 51 mais aussi de l'élément pivotant 40. Dans ce mode de réalisation, il est à remarquer que le raccord R2 ne joue pas le rôle de charnière.For the right or left fixing of the door P o provided with rotation-translation hinges, the stud 33 of the element 30 is introduced into the hole 18 located either on the right to the left, and the base 32 fixed on the door P 0 (figure 8). The support 41 of the pivoting element 40 which can occupy two positions at 180 ° from one another at the end of the sheath 51, into which it is inserted and then fixed, will be suitably placed in the sheath 51, then secured to the element 30 by means of the pin 46. The dimensions of the openings of the grid 1 allow the passage not only of the sheath 51 but also of the pivoting element 40. In this embodiment, it is note that the fitting R 2 does not act as a hinge.

Le dispositif d'alimentation électrique suivant l'invention, muni de raccords électriques R1 ou R2 à pivot tels que décrits et représentés, permet l'alimentation électrique d'un circuit U d'utilisation avec passage des fils de connexion dans la porte, que cette porte P ou Po, qui peut être munie de charnières du type à rotation ou à rotation-translation, soit montée de façon reversible, à droite ou à gauche, sans avoir à toucher au raccordement des fils f11, f21, sur le bloc 20 d'alimentation et au raccordement des fils f12, f22 sur le circuit U d'utilisation, en permettant la reversibilité de la porte par l'utilisateur et en respectant les règles de sécurité électrique.The electrical supply device according to the invention, provided with electrical connections R 1 or R 2 with pivot as described and shown, allows the electrical supply of a circuit U of use. tion with passage of the connection wires in the door, that this door P or P o , which can be provided with hinges of the rotation or rotation-translation type, is mounted reversibly, to the right or to the left, without having to touch the connection of the wires f 11 , f 21 , on the power supply unit 20 and the connection of the wires f 12 , f 22 on the circuit U of use, allowing the user to reverse the door and respecting electrical safety rules.

Dans un autre exemple de réalisation, une armoire de réfrigération suivant l'invention comprend, comme montré en figure 13, dans sa partie supérieure, un réfrigérateur F3 et, dans sa partie inférieure, un cogélateur C dont les portes respectives P1 et P2 sont réversibles, c'est-à-dire qu'elles peuvent être montées à droite ou à gauche de l'armoire.In another exemplary embodiment, a refrigeration cabinet according to the invention comprises, as shown in FIG. 13, in its upper part, a refrigerator F 3 and, in its lower part, a cogelator C whose respective doors P 1 and P 2 are reversible, that is to say they can be mounted on the right or left of the cabinet.

Le fourreau 103 de l'élément B, porteur du noyau 104 et fermé par le capuchon 109, est glissé sur la douille 101 solidaire de la porte P1 et soudé ou collé sur cette douille 101. La porte P1 est alors placée de façon que l'élément A formant pivot de charnière vienne s'introduire dans la douille 101.
This electrical connection W forming a hinge is mounted on the refrigeration cabinet as follows:
  • The element A is fixed to the upper part of the cabinet by means of the support S of which it is integral. The sheath 103 of the element B, carrying the core 104 and closed by the cap 109, is slid over the socket 101 secured to the door P 1 and welded or glued to this socket 101. The door P 1 is then placed so that the element A forming a hinge pivot is introduced into the socket 101.

Une seconde charnière de type classique connu, est fixée à la partie inférieure de l'armoire et de la porte P1.A second hinge of known conventional type is fixed to the lower part of the cabinet and of the door P 1 .

Afin d'assurer la non accessibilité des conducteurs électriques C1A et C2A lorsque la porte P1 est démontée, et observer les normes de sécurité électrique en vigueur, ces conducteurs ClA et C2A pouvant rester sous tension, la partie inférieure de l'élément A (demi-coquilles 102 et partie périphérique du pivot 124) est munie de chicanes 114 et 115 assurant une sécurité électrique suivant la norme en vigueur (figure 17).In order to ensure that electrical conductors C 1A and C 2A are not accessible when the door P 1 is removed, and observe the electrical safety standards in force, these conductors C lA and C 2A may remain live, the lower part of the element A (half-shells 102 and peripheral part of the pivot 124) is provided with baffles 114 and 115 ensuring electrical safety according to the standard in force (FIG. 17).

Le noyau 104 est muni, à sa partie supérieure, de chicanes 116, 117 qui viennent s'imbriquer dans les chicanes 114, 115 de l'élément A au moment du montage de la porte P1. Les ressorts 107 et 112 sont prévus pour venir pousser les conducteurs électriques C1B et C2B contre les conducteurs électriques C1A et C2A portés par l'élément A et établir ainsi un contact électrique permanent, même si la porte p1, sollicitée par son propre poids, subit des déplacements verticaux descendants.The core 104 is provided at its upper part with baffles 116, 117 which are nested in the baffles 114, 115 of the element A when the door P 1 is assembled. The springs 107 and 112 are provided to push the electrical conductors C 1B and C 2B against the electrical conductors C 1A and C 2A carried by the element A and thus establish a permanent electrical contact, even if the door p 1 , requested by its own weight, undergoes vertical downward movements.
