Description

Boîtier électronique à volet pivotant
La présente invention concerne un boîtier électronique comportant un clavier de touches et un volet de protection du clavier monté pivotant sous l'action de moyens de rappel d'une position de fermeture et de protection à une position d'ouverture et de fonctionnement.
Electronic box with pivoting flap
The present invention relates to an electronic unit comprising a keyboard of keys and a flap for protecting the keyboard pivotally mounted under the action of means for returning from a closed and protective position to an open and operating position.

Comme boîtiers électroniques de ce type, on peut citer les combinés de téléphone sans fil ou les boîtiers de télécommande.Examples of electronic boxes of this type are cordless telephone handsets or remote control boxes.

Ceux actuellement dans le commerce comportent, outre un organe de butée du volet en position d'ouverture, un ou deux ressorts d'ouverture montés dans les organes de pivotement du volet.Those currently on the market include, in addition to a shutter stop member in the open position, one or two opening springs mounted in the pivot members of the shutter.

L'entraînement d'une pièce mécanique en butée contre une autre n'est généralement pas très satisfaisant, sans parler de la place occupée par l'organe de butée au détriment d'autres composants. De surcroît, les ressorts sont montés dans leur logement avec un jeu aussi bien angulaire que transversal qui peut affaiblir le volet et contrarier sa fermeture.The driving of one mechanical part in abutment against another is generally not very satisfactory, not to mention the place occupied by the abutment member to the detriment of other components. In addition, the springs are mounted in their housing with a play both angular and transverse which can weaken the shutter and hinder its closing.

La présente invention vise à palier ces risques et inconvénients.The present invention aims to overcome these risks and drawbacks.

A cet effet, I'invention concerne un boîtier du type mentionné ci-dessus, caractérisé par le fait que les moyens de rappel comprennent des premiers moyens agencés pour faire pivoter le volet en deçà de sa position d'ouverture et des seconds moyens agencés pour faire pivoter le volet au-delà de sa position d'ouverture.To this end, the invention relates to a housing of the type mentioned above, characterized in that the return means comprise first means arranged to pivot the flap below its open position and second means arranged to rotate the shutter beyond its open position.

Jusqu'à la position de repos des premiers moyens de rappel, les premiers et seconds moyens exercent sur le volet une action motrice d'ouverture; au-delà, les seconds moyens d'ouverture continuent d'exercer une action motrice d'ouverture jusqu'à ce qu'elle soit compensée par l'action alors de freinage des premiers moyens, en position d'équilibre du volet. en deçà de la position de repos des seconds moyens de rappel. Up to the rest position of the first return means, the first and second means exert on the shutter a driving action of opening; beyond, the second opening means continue to exert an opening opening action until it is compensated by the then braking action of the first means, in the flap equilibrium position. below the rest position of the second return means.

Dans la forme de réalisation préférée du boîtier de l'invention, les moyens de rappel comprennent deux ressorts hélicoïdaux précontraints différemment en position de fermeture du volet. Ainsi. les angles d'armement des deux ressorts sont respectivement inférieur et supérieur à i'angle de pivotement du volet de sa position de fermeture à sa position d'ouverture.In the preferred embodiment of the housing of the invention, the return means comprise two helical springs which are prestressed differently in the closed position of the flap. So. the arming angles of the two springs are respectively less than and greater than the pivot angle of the flap from its closed position to its open position.

II est avantageux que l'une des extrémités de chaque ressort soit ancrée dans le boîtier et que l'autre extrémité soit Introduite dans une fente de détrompage d'un pivot du volet sur lequel est monté le ressort considéré. It is advantageous for one of the ends of each spring to be anchored in the housing and for the other end to be inserted into a keying slot on a pivot of the flap on which the spring in question is mounted.

L'invention sera mieux comprise à l'aide de la description suivante de la forme de réalisation préférée du boîtier de l'invention. en référence au dessin annexé, sur lequel - la figure 1 est une vue en perspective éclatée de la coque supérieure du boîtier, du volet de protection et des ressorts d'ouverture et - la figure 2 est une vue en perspective de la paire de ressorts d'ouverture.The invention will be better understood using the following description of the preferred embodiment of the housing of the invention. with reference to the accompanying drawing, in which - Figure 1 is an exploded perspective view of the upper shell of the housing, the protective flap and the opening springs and - Figure 2 is a perspective view of the pair of springs opening hours.

Le boîtier de l'invention, en l'espèce et ici un combiné de téléphone sans fil, comporte une paire de coques avant et arrière dont seule la coque avant 1 a été représentée sur la figure 1. vue de l'intérieur.The housing of the invention, in this case and here a cordless telephone handset, comprises a pair of front and rear shells of which only the front shell 1 has been shown in FIG. 1. seen from the inside.

La partie basse de la coque 1 est percée d'orifices 2 de passage de touches d'un clavier protégées, à l'état de repos. par un volet de protection extérieur 3.The lower part of the shell 1 is pierced with orifices 2 for passage of keys of a protected keyboard, in the rest state. by an external protective flap 3.

Le volet 3 est monté pivotant sur la coque 1 A 'étant de repos du boîtier, c'està-dire en position de fermeture du volet 3. celui-ci est plaqué contre la paroi extérieure 4 de la coque 3 et maintenu dans cette position par un mécanisme classique comportant. ici. un crochet 5 sur le volet 3 et une tige poussoir montée sur ressort et en saillie hors d'une paroi latérale 6 de la coque 1 par un orifice 7.The shutter 3 is pivotally mounted on the shell 1 A ′ being at rest of the housing, that is to say in the closed position of the shutter 3. the latter is pressed against the outer wall 4 of the shell 3 and held in this position by a conventional mechanism comprising. here. a hook 5 on the shutter 3 and a push rod mounted on a spring and projecting from a side wall 6 of the shell 1 through an orifice 7.

Le volet 3 comporte une portion principale 8 faisant fonction de couvercle, de laquelle s'étendent perpendiculairement at aux deux coins de la partie basse, opposée à la partie portant le crochet 5. deux joues latérales de pivotement 9, 10 portant respectivement deux pivots intérieurs 11. 12 d'axe 13. The shutter 3 comprises a main portion 8 acting as a cover, from which extend perpendicularly to the two corners of the lower part, opposite the part carrying the hook 5. two lateral pivot cheeks 9, 10 carrying respectively two inner pivots 11. 12 of axis 13.

II s'agit de pivots doubles. avec. chacun. un pivot central plein 14 et un manchon 15, plus court, autour du pivot 14. They are double pivots. with. each. a solid central pivot 14 and a shorter sleeve 15 around the pivot 14.

En partie basse extrême, les parois latérales 6 de la coque avant 1 ont été échancrées pour ménager un palier externe 16. 17. de forme sensiblement circulaire, support d'un manchon de pivotement 15 du volet 3. Parallèlement aux parois latérales 6 de la coque. à relativement faible distance des paliers 16, 17, s'étendent deux nervures Intérieures 18, 19 dans lesquelles sont ménagées des échancrures obliques 20. 21 pour faire fonction de paliers supports pour les pivots centraux 14 des deux joues de pivotement 9, 10 du volet.In the extreme lower part, the side walls 6 of the front shell 1 have been cut out to provide an external bearing 16. 17. of substantially circular shape, support for a pivoting sleeve 15 of the flap 3. Parallel to the side walls 6 of the shell. at a relatively short distance from the bearings 16, 17, extend two internal ribs 18, 19 in which oblique notches 20 are provided. 21 to act as support bearings for the central pivots 14 of the two pivot cheeks 9, 10 of the flap. .

Deux ressorts d'ouverture 22. 23 sont respectivemer.t montés sur les pivots 11, 12, glissés partiellement entre le pivot central 14 et le manchon 15 de ces pivots doubles. II s'agit de ressorts hélicoldaux avec une extrémité interne coudée 24, 25, d'ancrage dans la coque 1. et une extrémité externe 26, 27 glissée dans une fente latérale 28 du manchon 1 5 des pivots 11,12 du volet 3.Two opening springs 22. 23 are respectively mounted on the pivots 11, 12, partially slid between the central pivot 14 and the sleeve 15 of these double pivots. These are helical springs with a bent internal end 24, 25, for anchoring in the shell 1. and an external end 26, 27 slid into a lateral slot 28 of the sleeve 1 5 of the pivots 11, 12 of the flap 3.

Légèrement en deçà de la paroi transversale 29 de la coque 1, s'étendant entre les paliers 16, 17. et parallélement à elle s'étend, entre chaque palier externe 16, 17 et sa nervure palier associée 18. 19. une nervure 30. Chaque extrémité coudée 24. 25 des ressorts 22. 23 est glissée entre la nervure 30 correspondante et la paroi transversale 29 de la coque 1 pour y être ancrée.Slightly below the transverse wall 29 of the shell 1, extending between the bearings 16, 17. and parallel to it extends, between each external bearing 16, 17 and its associated bearing rib 18. 19. a rib 30 Each bent end 24. 25 of the springs 22. 23 is slid between the corresponding rib 30 and the transverse wall 29 of the shell 1 to be anchored there.

La fente latérale 28 de réception de l'autre extrémité des ressorts est inclinée sur un plan diamétral du manchon 15 des pivots 11 12, en sens inverse d'un pivot à l'autre, pour faire fonction de détrompage et éviter ainsi d'intervertir les ressorts 22, 23 respectivement associés aux deux joues de pivotement 9, 10 du volet.The lateral slot 28 for receiving the other end of the springs is inclined on a diametrical plane of the sleeve 15 of the pivots 11 12, in the opposite direction from one pivot to the other, to act as a polarization function and thus avoid reversing the springs 22, 23 respectively associated with the two pivot cheeks 9, 10 of the flap.

En position de fermeture du volet 3. Illustrée sur la figure 1. les ressorts 22, 23 sont précontraints. ou armés. mais différemment.In the closed position of the flap 3. Illustrated in FIG. 1. the springs 22, 23 are prestressed. or armed. but differently.

En référence à la figure 2. les extrémités externes des ressorts sont référencées 26, 27 en position de repos et 26' 27' en position de précontrainte. Referring to Figure 2. the outer ends of the springs are referenced 26, 27 in the rest position and 26 '27' in the preload position.

En position de précontrainte. les extrémités 26'. 27' des ressorts sont parallèles entre elles, leurs angles d'armement. en position de fermeture du volet 3, sont différents, celui du ressort 22 étant Inférieur à celui du ressort 23. ces deux angles d'armement. par exemple 95" et 175 respectivement, encadrant l'angle effectif d'ouverture du volet 3. soit 135" dans l'exemple considéré. In the prestressed position. the ends 26 '. 27 'of the springs are parallel to each other, their arming angles. in the closed position of the flap 3, are different, that of the spring 22 being lower than that of the spring 23. these two arming angles. for example 95 "and 175 respectively, framing the effective angle of opening of the shutter 3. ie 135" in the example considered.

En d'autres termes encore. quand on déclenche le mécanisme 5, 7 de fermeture du volet 3. jusqu'à la position de repos (26) du ressort 22, les deux ressorts exercent sur le volet 3 une action motrice d'ouverture; au-delà, le second ressort 23 continue d'exercer une action motrice, pas jusqu'en position de repos 27, mais jusqu'en position de repos intermédiaire du volet 3 dans laquelle l'action motrice du ressort 23 et l'action de freinage du ressort 22, générée au-delà de sa position de repos 26. se compensent mutuellement. In other words again. when the shutter closing mechanism 5, 7 is triggered 3. up to the rest position (26) of the spring 22, the two springs exert on the shutter 3 a driving action of opening; beyond, the second spring 23 continues to exert a driving action, not up to the rest position 27, but up to the intermediate rest position of the flap 3 in which the driving action of the spring 23 and the action of braking of the spring 22, generated beyond its rest position 26. compensate each other.
