Abstract

Description

La présente invention se rapporte à un dispositif de fixation de boucle de démagnétisation de téléviseur.The present invention relates to a device for fixing a television demagnetization loop.

Pour fixer une boucle de démagnétisation, on utilise généralement des dispositifs à ligatures élastiques. La mise en place de ces dispositifs connus doit se faire manuellement, ce qui ne permet pas toujours de disposer correctement la boucle par rapport au tube.To fix a demagnetization loop, elastic ligature devices are generally used. The establishment of these known devices must be done manually, which does not always allow to correctly arrange the loop relative to the tube.

La présente invention a pour objet un dispositif de fixation de boucle de démagnétisation de tube cathodique de téléviseur, dispositif qui soit simple et peu onéreux à réaliser, et qui permette d'automatiser la fixation optimale de la boucle, sans nécessiter d'intervention manuelle pendant ou après la fixation, ce dispositif ne dépendant pas des dimensions du tube cathodique.The subject of the present invention is a device for fixing a demagnetization loop of a cathode-ray tube of a television set, a device which is simple and inexpensive to produce, and which makes it possible to automate the optimal fixing of the loop, without requiring manual intervention during or after fixing, this device does not depend on the dimensions of the cathode ray tube.

Selon l'invention, le dispositif de fixation de boucle de démagnétisation comprend, pour chaque point de fixation de la boucle une pièce - support comportant au moins un crochet, pièce-support montée libre en rotation. Les points de fixation sont situés de préférence près des quatre coins de la dalle du tube cathodique. De préférence, ces quatre points de fixation sont les vis de fixation du tube cathodique dans l'ébénisterie du téléviseur. De façon avantageuse, les dispositifs de fixation sont montés libres en rotation sur la tête des vis de fixation du tube. Selon un mode de réalisation de l'invention, la pièce-support, qui est avantageusement moulée en matière plastique, comporte deux crochets formés sur une traverse symétriquement par rapport à la jonction de cette traverse avec une potence de support dont le pied comporte des moyens permettant de le fixer, libre en rotation, au point de fixation de la boucle.According to the invention, the demagnetization loop fixing device comprises, for each fixing point of the loop, a workpiece - support comprising at least one hook, workpiece support mounted free to rotate. The fixing points are preferably located near the four corners of the cathode ray tube slab. Preferably, these four fixing points are the fixing screws of the cathode ray tube in the cabinet of the television set. Advantageously, the fixing devices are mounted to rotate freely on the head of the tube fixing screws. According to one embodiment of the invention, the support piece, which is advantageously molded in plastic material, comprises two hooks formed on a cross member symmetrically with respect to the junction of this cross member with a support bracket whose foot comprises means allowing it to be fixed, free to rotate, at the attachment point of the loop.

La présente invention sera mieux comprise à la lecture de la description détaillée d'un mode de réalisation, pris comme exemple non limitatif, et illustré par le dessin annexé sur lequel :

  • - la figure 1 est une vue éclatée en perspective d'un dispositif de fixation conforme à l'invention, et
  • - la figure 2 est une vue en coupe axiale du dispositif de la figure 1, en position montée.
The present invention will be better understood on reading the detailed description of an embodiment, taken as a non-limiting example, and illustrated by the appended drawing in which:
  • FIG. 1 is an exploded perspective view of a fixing device according to the invention, and
  • - Figure 2 is an axial sectional view of the device of Figure 1, in the assembled position.

Le dispositif 1 de fixation de boucle de démagnétisation représenté sur le dessin est monté sur la tête 2 d'une vis 3 de fixation de tube cathodique (non représenté). Cette vis 3, par exemple du type autotaraudeuse, passe dans le trou d'une oreille de fixation 4 (partiellement représentée en figure 2) formée ou soudée sur la ceinture anti-implosion du tube cathodique, et est vissée dans un emplacement approprié de la façade du téléviseur. Habituellement, la ceinture anti-implosion comporte quatre telles oreilles de fixation se trouvant à peu près sur les diagonales de la dalle du tube cathodique sur laquelle elle est mise en place. La fixation du tube cathodique dans le coffret du téléviseur étant bien connue en soi, ne sera pas décrite plus en détail.The demagnetization loop fixing device 1 shown in the drawing is mounted on the head 2 of a screw 3 for fixing the cathode-ray tube (not shown). This screw 3, for example of the self-tapping type, passes through the hole of a fixing ear 4 (partially shown in FIG. 2) formed or welded on the anti-implosion belt of the cathode ray tube, and is screwed into a suitable location in the front of the TV. Usually, the anti-implosion belt has four such fixing ears located approximately on the diagonals of the slab of the cathode-ray tube on which it is placed. The fixing of the cathode ray tube in the TV cabinet being well known per se, will not be described in more detail.

La tête d'une vis de fixation de tube cathodique a généralement une forme de pavé hexagonal. Pour pouvoir monter le dispositif 1 sur une vis de fixation de tube cathodique, on modifie cette vis de la façon suivante. On forme sur la tête hexagonale 5 à l'opposé du corps de vis 6 un prolongement axial 7 de faible longueur, par exemple d'une longueur d'environ 5 à 10 mm. Ce prolongement 7 a la forme d'une tige cannelée.The head of a cathode ray tube fixing screw generally has the shape of a hexagonal block. In order to be able to mount the device 1 on a cathode-tube fixing screw, this screw is modified as follows. An axial extension 7 of short length, for example with a length of approximately 5 to 10 mm, is formed on the hexagonal head 5 opposite the screw body 6. This extension 7 has the shape of a grooved rod.

Le dispositif de fixation de boucle de démagnétisation proprement dit se compose essentiellement d'un pied 9 , d' une potence 10 formée sur le pied 9, d'une traverse 11 formée à l'extrémité de la potence 10, de deux dispositifs de crochets 12,13 formés aux extrémités de la traverse 11, et d'une barrette de guidage 14 formée sur le pied 9. L'ensemble de ces éléments du dispositif 1 est, de préférence, réalisé par moulage de matière plastique.The demagnetization loop fixing device proper consists essentially of a foot 9, a bracket 10 formed on the foot 9, a cross member 11 formed at the end of the bracket 10, two hook devices 12,13 formed at the ends of the cross member 11, and of a guide bar 14 formed on the foot 9. All of these elements of the device 1 are preferably made by molding of plastic material.

Le pied 9 a la forme d'une plaque de forme sensiblement carrée dont la zone centrale 15 est légèrement convexe (telle que vue de la potence 10), est de forme circulaire, a une épaisseur réduite, et comporte un trou axial dont le diamètre est sensiblement égal au diamètre de la partie 7A du prolongement 7. La zone 15 du pied 9 est fendue en croix par deux fentes diamétrales perpendiculaires entre elles, délimitant ainsi quatre secteurs circulaires. La zone 15 forme ainsi un circlips de fixation du dispositif 1 sur le prolongement 7 de la vis 3. Il suffit d'enfoncer à force le dispositif 1 sur le prolongement 7, les cannelures 8 faisant fléchir les quatre secteurs circulaires de la zone 15.The foot 9 has the shape of a substantially square plate whose central zone 15 is slightly convex (as seen from the stem 10), is circular in shape, has a reduced thickness, and has an axial hole whose diameter is substantially equal to the diameter of the part 7A of the extension 7. The area 15 of the foot 9 is split crosswise by two diametrical slots perpendicular to each other, thus delimiting four circular sectors. The zone 15 thus forms a retaining ring for fixing the device 1 to the extension 7 of the screw 3. It suffices to force the device 1 onto the extension 7, the grooves 8 causing the four circular sectors of the zone 15 to bend.

La potence 10 est formée au milieu de l'un des côtés du pied 9, perpendiculairement à ce pied. La traverse 11, formée à l'extrémité de la potence 10, se compose de deux bras identiques 11A,11B disposés symétriquement par rapport à la potence 10, perpendiculairement à celle-ci.The bracket 10 is formed in the middle of one of the sides of the foot 9, perpendicular to this foot. The cross member 11, formed at the end of the bracket 10, consists of two identical arms 11A, 11B arranged symmetrically with respect to the bracket 10, perpendicular to the latter.

Les dispositifs de crochets 12,13 comportent chacun essentiellement un corps 16,17, respectivement, en forme de barrette rectangulaire, un crochet 18,19 respectivement, formé à l'extrémité de la barrette près de sa liaison avec le bras 11A,11B, et une languette d'appui 20,21, respectivement, formée à l'autre extrémité de la barrette.The hook devices 12, 13 each essentially comprise a body 16, 17, respectively, in the form of a rectangular bar, a hook 18, 19 respectively, formed at the end of the bar near its connection with the arm 11A, 11B, and a support tab 20,21, respectively, formed at the other end of the bar.

Les barrettes 16,17 sont parallèles à la potence 10, dirigées vers le pied 9, et leur longueur est sensiblement égale à celle de la potence 10. Les barrettes 16,17 et les bras 11A, 11B sont coplanaires.The bars 16,17 are parallel to the bracket 10, directed towards the foot 9, and their length is substantially equal to that of the bracket 10. The bars 16,17 and the arms 11A, 11B are coplanar.

Les crochets 18,19 sont en forme de languettes repliées. Ces languettes comportent une partie plane 18A, 19A reliée par une partie coudée à l'extrémité de la barrette 16,17 correspondante, du côté de la jonction de celle-ci avec le bras 11A, 11B respectivement. Les parties planes 18A, 19A font un angle d'environ 30 à 50° avec le plan des barrettes 16,17, et sont dirigées à peu près vers la jonction entre le pied 9 et la barrette 14. La longueur des parties planes 18A,19A est égale ou légèrement inférieure à la moitié de la longueur des barrettes 16,17. Les dimensions respectives des parties planes 18A, 19A des barrettes 16,17 et la valeur de l'angle formé entre lesdites parties planes et les barrettes sont fonction du diamètre du câble 1A, formant la boucle de démagnétisation, et de l'espace dont on dispose dans l'ébénisterie du téléviseur. Pour un exemple de réalisation, la longueur des barrettes 16,17 est d'environ 25 mm, la longueur des parties planes 18A,19A d'environ 10 mm, et celle de leur angle par rapport au plan des barrettes 16,17 d'environ 40° pour un câble 1A d'un diamètre d'environ 6 à 10 mm.The hooks 18,19 are in the form of folded tabs. These tongues comprise a flat part 18A, 19A connected by a bent part to the end of the corresponding bar 16, 17, on the side of the junction of the latter with the arm 11A, 11B respectively. The flat parts 18A, 19A make an angle of about 30 to 50 ° with the plane of the bars 16, 17, and are directed approximately towards the junction between the foot 9 and the bar 14. The length of the flat parts 18A, 19A is equal or slightly less than half the length of the bars 16,17. The respective dimensions of the flat parts 18A, 19A of the bars 16, 17 and the value of the angle formed between said flat parts and the bars are a function of the diameter of the cable 1A, forming the demagnetization loop, and of the space which is has in the cabinetry of the TV. For an exemplary embodiment, the length of the bars 16.17 is approximately 25 mm, the length of the flat parts 18A, 19A of approximately 10 mm, and that of their angle relative to the plane of the bars 16.17 of approximately 40 ° for a 1A cable with a diameter of approximately 6 to 10 mm.

Les languettes d'appui 20,21 sont formées dans le prolongement des barrettes 16,17, leurs extrémités étant coudées à 90° à l'opposé de la vis 3. La longueur de ces languettes 20,21 est telle que lorsque le dispositif 1 en place sur la tête 2 de la vis 3 et que cette vis est vissée en place pour fixer le tube cathodique, les extrémités 20A,21A de ces languettes soient juste au contact de l'oreille 4.The support tongues 20,21 are formed in the extension of the bars 16,17, their ends being bent at 90 ° opposite to the screw 3. The length of these tongues 20,21 is such that when the device 1 in place on the head 2 of the screw 3 and that this screw is screwed in place to fix the cathode ray tube, the ends 20A, 21A of these tongues are just in contact with the ear 4.

La longueur de la barrette 14 est sensiblement égale à celle des barrettes 16,17. Cette barrette 14 comporte une première partie rectiligne 14A parallèle à la potence 10, qui s'étend à peu près jusqu'à la hauteur de l'extrémité18B,19B des crochets 18,19, et une seconde partie 14B, également rectiligne et parallèle à la potence 10, faisant un angle d'environ 10 à 20° avec la première partie, cette seconde partie s'écartant de la potence 10. La jonction entre les parties 14A et 14B est référencée 14C. On forme ainsi entre la partie 14B et les parties planes 18A,19A une ouverture évasée 22 d'introduction de câble dont l'angle est d'environ 40 à 50°. La partie la plus étroite de cette ouverture 22 se trouve entre la jonction 14C et les extrémités 18B,19B des parties 18A,19A. La largeur L de cette partie la plus étroite est légèrement inférieure (d'environ 1 à 3 mm) au diamètre du câble lA. Ainsi, grâce à l'élasticité de la barrette 14, et des crochets 18,19, dès que l'on fait pénétrer le c&ble 1A dans l'espace 23 compris entre la partie 14A et les barrettes 16,17, ce câble y reste prisonnier. Du fait que la traction exercée sur le câble 1A lors de la mise en place de la boucle de démagnétisation est dirigée à peu près parallèlement aux parties de languettes 18A,19A à l'opposé de la vis 3, le câble 1A vient alors se coincer entre les languettes 18,19 et les barrettes 16,17 respectivement, comme représenté en figure 2. Grâce à la disposition symétrique des crochets 18,19 par rapport à la potence 10 et au pied 9, grâce à la légère flexibllité de la potence 10 (dont la section est choisie en conséquence), grâce à la possibilité de rotation des dispositifs 1 autour de l'axe des vis 3, et grâce à la disposition des quatre dispositifs de fixation 1 dans la direction des diagonales de la dalle, la boucle de démagnétisation peut être simplement introduite par un automate dans ces quatre dispositifs de fixation sans avoir à être positionnée avec exactitude, et se place d'elle-même en position correcte, c'est-à-dire symétriquement par rapport aux axes 0x, Oy de l'écran, au plus près de la ceinture anti-implosion, et avec une tension suffisante de la boucle.The length of the bar 14 is substantially equal to that of the bars 16,17. This bar 14 has a first rectilinear part 14A parallel to the bracket 10, which extends approximately up to the height of the end 18B, 19B of the hooks 18,19, and a second part 14B, also rectilinear and parallel to the bracket 10, making an angle of about 10 to 20 ° with the first part, this second part deviating from the bracket 10. The junction between the parts 14A and 14B is referenced 14C. There is thus formed between the part 14B and the flat parts 18A, 19A a flared opening 22 for introducing a cable, the angle of which is approximately 40 to 50 °. The narrowest part of this opening 22 is located between the junction 14C and the ends 18B, 19B of the parts 18A, 19A. The width L of this narrowest part is slightly less (about 1 to 3 mm) than the diameter of the cable lA. Thus, thanks to the elasticity of the bar 14, and of the hooks 18, 19, as soon as the cable 1A is penetrated into the space 23 between the part 14A and the bars 16.17, this cable remains trapped there. Due to the fact that the traction exerted on the cable 1A during the positioning of the demagnetization loop is directed approximately parallel to the parts of tabs 18A, 19A opposite the screw 3, the cable 1A then gets stuck between the tongues 18,19 and the bars 16,17 respectively, as shown in FIG. 2. Thanks to the symmetrical arrangement of the hooks 18,19 relative to the bracket 10 and to the foot 9, thanks to the slight flexibility of the bracket 10 (whose section is chosen accordingly), thanks to the possibility of rotation of the devices 1 around the axis of the screws 3, and thanks to the arrangement of the four fixing devices 1 in the direction of the diagonals of the slab, the loop demagnetization can be simply introduced by an automaton in these four fixing devices without having to be positioned with exactitude, and places itself in the correct position, that is to say symmetrically with respect to the a xes 0x, Oy of the screen, as close as possible to the anti-implosion belt, and with sufficient tension of the buckle.

On remarquera que les languettes 20,21, qui sont légèrement élastiques, empêchent une flexion exagérée de la potence 10 par suite des efforts exercés par la boucle de démagnétisation, en particulier lors de sa mise en place.It will be noted that the tongues 20, 21, which are slightly elastic, prevent an exaggerated bending of the stem 10 as a result of the forces exerted by the demagnetization loop, in particular during its installation.

Les pièces 1 de l'invention sont standard quels que soient le type et la taille du tube cathodique, les vis de fixation 3 étant standard.The parts 1 of the invention are standard whatever the type and size of the cathode ray tube, the fixing screws 3 being standard.
