Description

L'invention concerne un clavier constitué d'un chassis muni entre autres d'une touche allongée, par exemple une barre d'espacement, de moyens de coulissage de cette tou­che, et d'un palonnier destiné à éviter que la touche ne s'en­fonce de travers, palonnier oscillant autour d'un axe lié au chassis et perpendiculaire à la direction dudit coulissage, et comportant au moins deux broches, chacune coulissant dans une fente ménagée dans la touche penpendiculairement à la direc­tion dudit coulissage.The invention relates to a keyboard consisting of a chassis provided inter alia with an elongated key, for example a space bar, means for sliding this key, and a spreader intended to prevent the key from being pressed sideways, spreader oscillating about an axis linked to the chassis and perpendicular to the direction of said sliding, and comprising at least two pins, each sliding in a slot formed in the key perpendicular to the direction of said sliding.

Des claviers selon l'invention sont employés par exemple dans des matériels de traitement de données tels que des mini-ordinateurs.Keyboards according to the invention are used for example in data processing equipment such as minicomputers.

Des barres d'espacement munies de palonniers selon le préambule ci-dessus sont présentes dans un clavier d'ordi­nateur disponible dans le commerce. Les broches du palonnier y sont engagées dans des fentes de la touche et l'axe du palon­nier est tenu par des pièces intermédiaires rigides, elles mêmes rapportées et fixées au chassis par clipsage. Le montage de ce système est possible en amenant ensemble la touche, le palonnier et lesdites pièces intermédiaires sur le chassis. Pour mécaniser ce montage, un système complexe serait néces­saire pour maintenir et positionner ensemble toutes ces piè­ces. En outre, le démontage n'est possible qu'en accédant préalablement au-dessous du chassis pour libérer lesdites piè­ces intermédiaires.Space bars provided with spreaders according to the preamble above are present in a commercially available computer keyboard. The spreader pins are engaged in key slots and the spreader axis is held by rigid intermediate parts, themselves attached and fixed to the chassis by clipping. The assembly of this system is possible by bringing together the key, the spreader and said intermediate parts on the chassis. To mechanize this assembly, a complex system would be necessary to hold and position all these parts together. In addition, disassembly is only possible by accessing the underside of the chassis beforehand to release said intermediate parts.

L'invention a pour but de procurer un clavier dont le montage et le démontage sont grandement facilités. Dans le clavier selon l'invention, le palonnier peut être mis en place à l'avance sur le chassis, et le montage est complété par le seul ajout de la touche nue, qu'il suffit d'enfoncer a force pour la mettre en place. Le démontage est aussi aisé puisqu'il suffit de tirer suffisamment fort sur la touche.The invention aims to provide a keyboard whose assembly and disassembly are greatly facilitated. In the keyboard according to the invention, the lifter can be put in place on the chassis in advance, and the assembly is completed by the only addition of the bare key, which suffices to press down forcefully to put it in square. Disassembly is also easy since it suffices to pull hard enough on the key.

A cet effet, un clavier selon l'invention est no­tamment remarquable en ce que, chaque fente étant ouverte à une extrémité pour permettre l'entrée de la broche, la touche est munie d'un plan incliné conduisant vers l'ouverture de la fente, dans la direction allant du chassis vers la touche, et les moyens de liaison entre l'axe du palonnier et le chassis comportent une partie élastique pour permettre un déplacement dudit axe dans la direction qui permet aux broches du palon­nier de suivre le plan incliné et d'entrer dans la fente.To this end, a keyboard according to the invention is notably remarkable in that, each slot being open at one end to allow entry of the spindle, the key is provided with an inclined plane leading towards the opening of the slot , in the direction from the chassis to the key, and the connecting means between the axis of the lifter and the chassis comprise an elastic part to allow movement of said axis in the direction which allows the pins of the lifter to follow the inclined plane and to enter the slot.

Avantageusement l'ouverture de la fente est tournée vers l'extérieur de la touche.Advantageously, the opening of the slot is turned towards the outside of the button.

Dans un mode de réalisation particulier le palon­nier est fixé au chassis par au moins un crochet élastique dont le débattement est suffisant pour permettre l'introduc­tion des broches dans les fentes. Ce crochet comporte avanta­geusement une partie repliée destinée a augmenter sa longueur effective, et par conséquent son élasticité et son débatte­ment.In a particular embodiment, the lifter is fixed to the chassis by at least one elastic hook whose clearance is sufficient to allow the introduction of the pins into the slots. This hook advantageously comprises a folded part intended to increase its effective length, and consequently its elasticity and its clearance.

Dans une forme de réalisation industrielle, le cro­chet élastique est avantageusement moulé d'une seule pièce avec le chassis, en matière plastique.In an industrial embodiment, the elastic hook is advantageously molded in one piece with the chassis, made of plastic.

La description qui va suivre, en regard des dessins annexés décrivant des exemples non limitatif fera bien com­prendre comment l'invention peut être réalisée.

  • La figure 1 représente un clavier.
  • La figure 2 représente en perspective les pièces du système de touche longue, séparées les unes des autres.
  • La figure 3 représente une coupe selon le plan A de la figure 2, d'un ensemble monté.
The description which follows, with reference to the appended drawings describing nonlimiting examples will make it clear how the invention can be implemented.
  • Figure 1 shows a keyboard.
  • Figure 2 shows in perspective the parts of the long key system, separated from each other.
  • Figure 3 shows a section along plane A of Figure 2, of a mounted assembly.

Sur le clavier de la figure 1 est indiquée en 4 la touche allongée dite barre d'espacement, qui est concernée par l'invention.On the keyboard of FIG. 1 is indicated at 4 the elongated key called space bar, which is concerned with the invention.

Sur la figure 2 la touche proprement dite 4 est re­présentée la tête en bas par rapport aux autres éléments de la figure afin de montrer des parties qui sont situées normale­ment sous la touche. Les flèches 16 indiquent le mouvement a réaliser pour amener la touche en position convenable.In Figure 2 the key itself 4 is shown upside down with respect to the other elements of the figure in order to show parts which are normally located under the key. Arrows 16 indicate movement to be carried out to bring the key into the suitable position.

La touche est munie de moyens de coulissage 5, 6 connus et qui ne font pas partie de l'invention. Ils compor­tent un tube central 5 destiné à coulisser dans un canon 18 porté par le chassis, et des parties de cylindre 6 qui servent à emprisonner un ressort de rappel (non représenté) et à fixer la touche en s'accrochant par des ergots à un relief 21 ménagé autour du canon 18. Ce canon est maintenu au centre d'un trou annulaire 20 par quatre ailettes 19. Les éléments 6 peuvent coulisser dans ce trou annulaire et les ailettes passent entre les éléments 6. C'est en outre le tube 5 qui appuie sur des moyens de contact électrique non représentés.The key is provided with known sliding means 5, 6 which are not part of the invention. They comprise a central tube 5 intended to slide in a barrel 18 carried by the chassis, and cylinder parts 6 which serve to trap a return spring (not shown) and to fix the key by being hooked by lugs to a relief 21 formed around the barrel 18. This barrel is held in the center of an annular hole 20 by four fins 19. The elements 6 can slide in this annular hole and the fins pass between the elements 6. It is also the tube 5 which presses on electrical contact means not shown.

Le palonnier destiné à éviter que la touche ne s'enfonce de travers est constitué ici d'un fil d'acier dont le diamètre est d'environ 1,5mm, dont la partie 8 constitue un axe d'oscillation, et dont chaque extrémité est repliée deux fois à angle droit pour constituer, à chaque extrémité, une broche 9 parallèle à l'axe 8, c'est à dire ici horizontale, et par conséquent perpendiculaire à la direction du coulissage qui est ici verticale.The lifter intended to prevent the key from sinking crookedly consists here of a steel wire whose diameter is approximately 1.5mm, of which part 8 constitutes an axis of oscillation, and each end of which is folded twice at right angles to form, at each end, a pin 9 parallel to the axis 8, that is to say here horizontal, and therefore perpendicular to the direction of sliding which is here vertical.

La touche 4 comporte à chaque extrémité une patte 15 dans laquelle est ménagée une fente 3 perpendiculaire à la direction du coulissage, c'est à dire ici horizontale. La fen­te 3 est ouverte à une extrémité qui est ici tournée vers l'extérieur de la touche. Pour montrer comment se fait l'as­semblage, on a indiqué avec le palonnier 8, 9 la position nor­male des pattes 15 (et pas la touche entière qui aurait caché le dispositif), montrant comment les broches 9 pénétrent dans les fentes 3.The key 4 has at each end a tab 15 in which is formed a slot 3 perpendicular to the direction of sliding, that is to say horizontal here. The slot 3 is open at one end which is here turned towards the outside of the button. To show how the assembly is done, we indicated with the lifting beam 8, 9 the normal position of the legs 15 (and not the entire key which would have hidden the device), showing how the pins 9 penetrate into the slots 3.

L'axe du palonnier oscillant est lié au chassis par des crochets 1 qui sont indiqués schématiquement au niveau du palonnier, et représentés plus en détail au-dessous. Le cro­chet 1 est disposé en face d'un relief 12 de façon à emprison­ner la partie 8 du palonnier entre le crochet 1 et le relief 12. En outre, une paroi verticale 10 permet d'appuyer contre elle la partie 7 des pattes 15, comme le suggère la flèche 17, pour empêcher la touche de tourner autour d'un axe vertical, et un trou rectangulaire 11 permet aux pattes 15 de s'enfoncer, lorsqu'on appuie sur la touche.The axis of the swinging spreader is linked to the chassis by hooks 1 which are shown diagrammatically at the spreader, and shown in more detail below. The hook 1 is arranged opposite a relief 12 so as to trap the part 8 of the lifter between the hook 1 and the relief 12. In addition, a vertical wall 10 makes it possible to press against it the part 7 of the legs 15, as the arrow 17 suggests, to prevent the key from turning around a vertical axis, and a rectangular hole 11 allows the legs 15 to sink, when the key is pressed .

Les pattes 15 sont munies d'un plan incliné 2, dont le rôle sera mieux compris grâce à la coupe de la figure 3.The legs 15 are provided with an inclined plane 2, the role of which will be better understood thanks to the section of FIG. 3.

Sur la figure 3, l'ensemble est représenté monté, dans la position de repos de la touche. Les éléments déjà dé­crits à propos de la figure 2 y portent les mêmes numéros de référence. Le chassis est indiqué par la référence 13, et la broche 9 est représentée dans une position de repos 9A et dans une position 9B qui a deux fonctions. D'une part, lorsqu'on appuie sur la touche le palonnier tourne autour de son axe 8 et la broche passe de la position 9A à la position 9B, cepen­dant que la partie 7 glisse le long de la paroi verticale 10. D'autre part, pour assembler la touche au clavier lors de la fabrication, on met d'abrod en place le palonnier dans la po­sition 9B. L'axe 8 est maintenu entre le crochet 1 et le re­lief 12, et le palonnier repose à plat sur le chassis. On n'a donc pas besoin de prévoir d'outillage pour le maintenir. Lorsqu'on amène la touche et qu'on l'enfonce, le plan incliné 2 vient s'insérer à droite de la broche 9B, et au fur et à me­sure que la touche descend, le palonnier se déplace vers la gauche grâce à l'élasticité du crochet 1, élasticité suffisan­te pour permettre un déplacement de l'axe 8 dans la direction qui permet à la broche 9B de suivre le plan incliné et d'en­trer en fin d'enfoncement de la touche dans la fente 3 où elle reste alors prisonnière.In Figure 3, the assembly is shown mounted, in the rest position of the key. The elements already described in connection with FIG. 2 bear the same reference numbers there. The chassis is indicated by the reference 13, and the spindle 9 is shown in a rest position 9A and in a position 9B which has two functions. On the one hand, when the key is pressed the lifter turns around its axis 8 and the spindle goes from position 9A to position 9B, while part 7 slides along the vertical wall 10. On the other hand hand, to assemble the key to the keyboard during manufacture, we put abrod in place the lifter in position 9B. The axis 8 is held between the hook 1 and the relief 12, and the lifter rests flat on the chassis. There is therefore no need to provide tools to maintain it. When the button is brought in and pressed, the inclined plane 2 is inserted to the right of pin 9B, and as the button goes down, the lifter moves to the left thanks to the elasticity of the hook 1, sufficient elasticity to allow movement of the axis 8 in the direction which allows the pin 9B to follow the inclined plane and to enter at the end of pressing the key in the slot 3 where it remains so a prisoner.

Au début de l'enfoncement, les ergots des éléments 6 du système de coulissage de la figure 2 s'enclenchent dans le relief 21 du canon 18 et empêchent par la suite la touche de remonter plus haut que la position représentée sur la figure 3. Pour assurer une élasticité suffisante du crochet, la longueur effective de ce dernier est augmentée, du fait qu'à partir de son point de raccordement au chassis, il est d'abord dirigé vers le bas, puis est replié en 14 pour se di­riger ensuite vers le haut. Dans la réalisation représentée, le chassis 13, la paroi 10, le crochet 1, 14 et le relief 12 sont tous moulés ensemble dans une matière plastique, par exemple celle dénommée ABS.At the start of the insertion, the lugs of the elements 6 of the sliding system of FIG. 2 engage in the relief 21 of the barrel 18 and subsequently prevent the key from going back higher than the position shown in FIG. 3. To ensure sufficient elasticity of the hook, the effective length of the latter is increased, since from its point of connection to the chassis, it is first directed downwards, then is folded at 14 to then direct upwards. In the embodiment shown, the frame 13, the wall 10, the hook 1, 14 and the relief 12 are all molded together in a plastic material, for example that called ABS.

En ce qui concerne le démontage, un moyen consiste à insérer un outil qui déplace le crochet 1 vers la gauche, la touche étant enfoncée, ce qui pousse la broche 9B hors de la fente 3 après quoi on n'a plus qu'à laisser remonter la touche. Un autre moyen, avec lequel le démontage est encore plus facile consiste à prévoir une fente 3 plus profonde que ne le requiert le déplacement normal de la touche, ainsi que cela est suggéré par le dessin en pointillé 30. Alors, il suf­fit de tirer la touche vers le haut assez fort pour libérer le clipsage 6, 21 des moyens de coulissage, et lorsque le bas de la partie 7 arrive à la hauteur du haut de la paroi 10, la touche peut se libérer vers la droite.Regarding disassembly, one way is to insert a tool that moves the hook 1 to the left, the key being pressed, which pushes the pin 9B out of the slot 3 after which we just have to leave raise the button. Another means, with which disassembly is even easier, is to provide a deeper slot 3 than the normal displacement of the key requires, as is suggested by the dotted line 30. Then, it suffices to pull the key up strong enough to release the clipping 6, 21 of the sliding means, and when the bottom of the part 7 reaches the height of the top of the wall 10, the key can be released to the right.

Bien entendu, d'autres modes de réalisation de l'invention sont possibles. En particulier le crochet peut avoir d'autres formes, on peut imaginer notamment une sorte de pène associé à un ressort, comme celui d'une serrure.Of course, other embodiments of the invention are possible. In particular the hook can have other shapes, one can imagine in particular a kind of bolt associated with a spring, like that of a lock.

La fente 3 peut aussi être tournée vers l'intérieur de la touche, le crochet étant alors tourné dans l'autre sens (c'est à dire que son élasticité permettrait dans le cas de la figure 3 de pousser le palonnier vers la droite). Néanmoins, cette solution est moins favorable car elle laisse moins de largeur disponible pour le palonnier, à moins que ce dernier ne déborde à l'extérieur de la touche, ce qui n'est pas sou­haitable. Pour des petites séries, un groupe d'éléments 1, 10, 11, 12 peut être constitué par une petite pièce indépendante qui est rapportée sur le chassis. Au lieu d'utiliser un relief 12 en face du crochet 1, on peut aussi munir ce dernier, à son extrémité, d'une sorte de pince emprisonnant l'axe du palon­nier.The slot 3 can also be turned towards the inside of the key, the hook then being turned in the other direction (that is to say its elasticity would make it possible, in the case of FIG. 3, to push the lifter to the right) . However, this solution is less favorable because it leaves less width available for the lifter, unless the latter overflows outside the key, which is not desirable. For small series, a group of elements 1, 10, 11, 12 can be constituted by a small independent part which is attached to the chassis. Instead of using a relief 12 opposite the hook 1, it is also possible to provide the latter, at its end, with a sort of clamp trapping the axis of the lifter.
