Description

La présente invention concerne un boitier à ouverture et fermeture rapide.The present invention relates to a housing quick opening and closing.

On connaít des boítiers, en particulier des boítiers contenant un émetteur-récepteur hertzien, comportant un caisson cylindrique et un couvercle circulaire fixé au caisson par un dispositif de fermeture formé par un profilé cintré ayant une section en U et dont les extrémités repliées sont équipées de moyens de tension du type vis/écrou.We know of cases, in particular housings containing a wireless transceiver, comprising a cylindrical box and a fixed circular cover to the box by a closing device formed by a curved profile having a U-shaped section and the folded ends are equipped with tensioning means screw / nut type.

Le caisson cylindrique ne peut recevoir que des cartes électroniques circulaires qui présentent une surface relativement faible par rapport à leur diamètre et peuvent donc supporter un nombre limité de composants.The cylindrical box can only receive circular electronic cards that have a surface relatively small compared to their diameter and can therefore support a limited number of components.

Par ailleurs on connaít du document FR-A-2.060.199 un boítier comprenant un caisson de section carrée auquel est associé un couvercle de forme correspondante, le couvercle étant fixé au caisson par un profilé serti au moyen d'une molette. Un tel boítier ne peut pas être ouvert ou fermé aisément et ne pourrait donc pas être utilisé pour un boítier électronique de relais hertzien sur lequel il est nécessaire de pouvoir intervenir avec une perte de temps minimale pour l'ouverture et la fermeture du boítier.Furthermore we know of the document FR-A-2.060.199 a case including a section box square with associated shape cover corresponding, the cover being fixed to the box by a profile crimped using a thumb wheel. Such a case does not cannot be opened or closed easily and therefore cannot not be used for an electronic relay box radio on which it is necessary to be able to intervene with minimal loss of time for opening and closing the case.

On connaít également des documents US-A-1.467254 et 2.548.216 des dispositifs de liaison de rebords circulaires de bidons ou de tuyaux comprenant une série de segments de profilés portés par une bande flexible équipée de moyens de mise en tension.We also know documents US-A-1.467254 and 2,548,216 edge connection devices circulars of cans or pipes comprising a series of profile segments carried by a flexible band fitted tensioning means.

Cependant le dispositif de fixation décrit dans ces documents ne pourrait pas être transposé directement sur le boítier du document FR-A-2.060.199 car les segments de profilé ne seraient pas maintenus selon un appui suffisant sur les côtés rectilignes du boítier du document FR-A-2.060.199.However, the fixing device described in these documents could not be transposed directly on the case of document FR-A-2.060.199 because the segments profile would not be maintained according to a support sufficient on the rectilinear sides of the document box FR-A-2.060.199.

Selon l'invention on propose un boítier comprenant un caisson de forme sensiblement polygonale et un couvercle de forme correspondante, le caisson et le couvercle ayant des côtés incurvés avec une concavité tournée vers l'intérieur du boítier, et le boítier étant équipé d'un dispositif de fermeture de boítier comportant des séries de segments de profilé rectilignes portés par une bande flexible équipée de moyens de mise en tension.According to the invention there is provided a housing comprising a box of substantially polygonal shape and a correspondingly shaped cover, the box and the cover having curved sides with a concavity facing the inside of the case, and the case being fitted with a housing closing device comprising series of rectilinear profile segments carried by a flexible strip equipped with tensioning means.

Ainsi les côtés incurvés vers l'intérieur du boítier selon l'invention constituent des arcs-boutants pour les segments de profilés de sorte que le dispositif de fermeture assure un maintien ferme du couvercle contre le rebord du caisson en dépit de la forme polygonale de celui-ci tout en offrant un volume plus grand qu'un boítier circulaire pour un même encombrement et permettant en outre un blindage plus aisé du circuit électronique dans le cas d'un émetteur-récepteur hertzien.So the sides curved inward of the housing according to the invention constitute flying buttresses for profile segments so that the closure ensures that the cover remains firmly against the rim of the box despite the polygonal shape of it while offering a volume larger than a case circular for the same size and also allowing easier shielding of the electronic circuit in the case of a wireless transceiver.

D'autres caractéristiques et avantages de l'invention apparaítront à la lecture de la description qui suit d'un mode de réalisation particulier non limitatif de l'invention, en relation avec les figures ci-jointes parmi lesquelles :

  • la figure 1 est une vue en perspective partiellement interrompue d'un dispositif de fermeture du boítier selon 1' invention,
  • la figure 2 est une vue en perspective agrandie d'une série de segments de profilé rectilignes selon le mode de réalisation préféré de l'invention,
  • la figure 3 est une vue en perspective avec un écorché d'un boítier équipé du dispositif selon l'invention.
Other characteristics and advantages of the invention will appear on reading the following description of a particular non-limiting embodiment of the invention, in relation to the attached figures among which:
  • FIG. 1 is a partially interrupted perspective view of a device for closing the housing according to the invention,
  • FIG. 2 is an enlarged perspective view of a series of straight profile segments according to the preferred embodiment of the invention,
  • Figure 3 is a perspective view with a sectional view of a housing equipped with the device according to the invention.

En référence aux figures, le dispositif de fermeture de boítier selon le mode de réalisation préféré illustré comporte une bande porteuse 1, par exemple une bande métallique du type utilisé pour réaliser des colliers de serrage, équipée à l'une de ses extrémités d'un mécanisme à vis sans fin 2 et comportant à l'autre extrémité des fentes 3 adaptées à coopérer avec le mécanisme à vis sans fin 2.With reference to the figures, the device for case closure according to the preferred embodiment illustrated comprises a carrier strip 1, for example a metal band of the type used to make necklaces clamp, fitted at one end with a mechanism worm 2 and having at the other end slots 3 adapted to cooperate with the screw mechanism endless 2.

Par ailleurs le dispositif de fermeture de boítier comporte quatre modules 4 de segments de profilé généralement désignés en 5. Comme illustré par la figure 2, chaque module comporte une série de segments de profilé réalisés en une seule pièce par découpage d'une bande métallique pour délimiter des ailes 6 de part et d'autre d'une âme centrale 7, puis repliage des ailes 6 pour former les segments de profilé 5.In addition, the closing device of housing includes four modules 4 of profile segments generally designated in 5. As illustrated in Figure 2, each module has a series of profile segments made in one piece by cutting a strip metallic to delimit wings 6 on both sides a central core 7, then folding the wings 6 to form profile segments 5.

Comme illustré par la figure 3, chaque module 4 de segments de profilé rectilignes est fixé à la bande porteuse 1 par deux points de soudure 8.As illustrated in Figure 3, each module 4 of straight profile segments is fixed to the strip carrier 1 by two welding points 8.

Le dispositif de fermeture selon le mode de réalisation préféré illustré est destiné à être monté sur un boítier comportant un caisson 9 et un couvercle 11 de forme sensiblement carrée et ayant des côtés, respectivement 10 et 12, légèrement incurvés, dont la concavité est tournée vers l'intérieur du boítier. Les côtés sont reliés par les portions de paroi de caisson et des portions de bord de couvercle également concaves dont le rayon de courbure est plus faible que le rayon de courbure des côtés.The closing device according to the mode of preferred embodiment illustrated is intended to be mounted on a housing comprising a box 9 and a cover 11 of substantially square in shape and having sides, respectively 10 and 12, slightly curved, whose concavity is facing the inside of the case. The sides are connected by the housing wall portions and portions of cover edge also concave whose radius of curvature is smaller than the radius of curvature of sides.

Dans ce mode de réalisation, les modules 4 de segments de profilé sont espacés les uns des autres de façon à venir en regard des côtés légèrement incurvés du boítier lorsque le dispositif de fermeture est présenté avec les segments de profilé à cheval sur le couvercle et sur un rebord 13 du caisson en saillie vers l'extérieur. Lors de la mise en place du dispositif de fermeture, les segments de profilé assurent un centrage de la bande porteuse 1 par rapport aux bords du couvercle 11 et du rebord 13. Lors du serrage du dispositif de fermeture au moyen du mécanisme 2, les segments de profilé 5 sont appliqués de façon homogène de sorte que le couvercle 11 est maintenu fermement appliqué sur le caisson 13. A cet effet les ailes 6 de segments de profilé 5 sont de préférences inclinées l'une par rapport à l'autre et le couvercle 11 comporte le long de son bord un biseau 14 sur lesquelles les ailes 6 prennent appui.In this embodiment, the modules 4 of profile segments are spaced from each other by way to come opposite the slightly curved sides of the case when the closing device is presented with the profile segments straddling the cover and on a rim 13 of the box projecting outwards. When installing the closing device, the profile segments ensure centering of the strip carrier 1 relative to the edges of the cover 11 and the flange 13. When tightening the closing device to the by means of mechanism 2, the profile segments 5 are applied evenly so that the cover 11 is kept firmly applied to the casing 13. At this effect the wings 6 of profile segments 5 are preferred inclined relative to each other and the cover 11 has along its edge a bevel 14 on which the wings 6 are supported.

Bien entendu l'invention n'est pas limitée au mode de réalisation illustré et on peut y apporter des variantes de réalisation sans sortir du cadre de l'invention tel que défini par les revendications.Of course, the invention is not limited to illustrated embodiment and we can bring variant embodiments without departing from the scope of the invention as defined by the claims.

En particulier, bien que les séries de segments de profilé aient été décrites sous forme d'un module en une seule pièce, on pourra réaliser des segments de profilé séparés associés individuellement à la bande porteuse 1, en particulier dans le cas où le boítier a une forme irrégulière. A l'inverse les segments de profilé pourront être réalisés en une seule pièce avec la bande porteuse 1 par découpage et pliage d'une bande de largeur appropriée, ce qui permettra de supprimer l'opération d'assemblage des segments de profilé avec la bande porteuse.In particular, although the series of segments have been described in the form of a module in one single piece, we can make profile segments separated individually associated with the carrier strip 1, in especially in the case where the housing has an irregular shape. Conversely, the profile segments can be made in one piece with the carrier strip 1 by cutting and folding a strip of suitable width, this which will remove the assembly operation of profile segments with the carrier strip.
