Abstract

The device has a box body (1) on which a spike (11) is positioned, where the body is arranged on a support (10). The support authorizes vertical displacement of the spike. A projecting part is placed on the support. A groove (20) is formed on a battery compartment (2). A hole (21) guides and receives the spike. An upper face of the spike forms an angle higher than angle of the groove. The angle unlocks the compartment from the body by any object of diameter lower than diameter of the hole and to translate the compartment from the body.

Description

La présente invention à pour objet un dispositif mécanique pour verrouiller et déverrouiller aisément une trappe à piles dans un boitier électronique portable grand public. Dans les produits électroniques portables et nomades, il est courant d'utiliser des sources d'énergies que l'on peut changer lorsque leurs charges électriques sont devenues insuffisantes. Ces sources d'énergies sont souvent des accumulateurs de type pile. Dans ces produits, pour des raisons de réglementation, de conception, voir de prix de revient, ces piles sont insérées dans le corps du produit et électriquement isolées de l'extérieur par une trappe fixée mécaniquement par au moins un élément de serrage, le plus souvent une vis. Dans les cas, ou il n'existe pas de vis, le verrouillage et le déverrouillage de la trappe se fait par emboitement mécanique entre le corps du boitier et la trappe à pile. Ces systèmes présentent l'inconvénient d'être difficilement recyclable (dans les cas d'utilisation de vis), relativement lourd et d'un prix de revient non négligeable pour le marché visé par ce type de produit grand public. De plus, lors de l'utilisa ion de système sans vis, il est souvent difficile d'ouvrir la trappe pour en extraire les piles, voire de détériorer les parties mécaniques permettant le verrouillage. The present invention relates to a mechanical device for easily locking and unlocking a battery door in a portable consumer electronic box. In portable and nomadic electronic products, it is common to use sources of energy that can be changed when their electrical charges have become insufficient. These sources of energy are often battery-type accumulators. In these products, for reasons of regulation, design, or cost, these batteries are inserted into the body of the product and electrically insulated from the outside by a hatch fixed mechanically by at least one clamping element, the most often a screw. In cases where there is no screw, the locking and unlocking of the hatch is by mechanical interlocking between the body of the housing and the battery door. These systems have the disadvantage of being difficult to recycle (in the case of use of screws), relatively heavy and a significant cost price for the market targeted by this type of consumer product. In addition, when using a system without screws, it is often difficult to open the hatch to extract the batteries, or even to deteriorate the mechanical parts for locking.

La présente invention pallie ces inconvénients. Elle vise un système du type en question utilisant un picot de verrouillage positionné sur un support flexible disposé dans le corps du boitier portable interagissant avec une échancrure insérée dans le corps de la trappe à pile. Ce dispositif pour assembler et désassembler deux parties mécaniques, comprenant une première partie (1) sur laquelle est positionné un picot (Il) disposé sur un support (10), ledit support autorisant un déplacement vertical dudit picot (Il) et une partie saillante (12) disposé sur ledit support (10) et une seconde partie (2) dans laquelle est créée une gorge (20) et un trou (21) aptes à guider et à réceptionner ledit picot (11), se caractérise en ce que la face supérieure dudit picot (11) possède un angle qui est au moins supérieur à celui présenté par ladite gorge et que ledit angle dudit picot permettant, lors de son appui par un objet quelconque d'un diamètre inférieur à celui dudit trou, d'une part, de déverrouiller la seconde partie (2) de la première (1) et d'autre part, de faire translater la seconde partie (2) de la première (1) facilitant ainsi son extraction. La manière dont l'invention peut être réalisée et les avantages qui en découlent ressortiront mieux des exemples de réalisation qui suivent, donnés à titre indicatif et non limitatif, à l'appui des figures annexées. The present invention overcomes these disadvantages. It aims a system of the type in question using a locking pin positioned on a flexible support disposed in the body of the portable housing interacting with a notch inserted in the body of the battery door. This device for assembling and disassembling two mechanical parts, comprising a first part (1) on which is positioned a pin (II) disposed on a support (10), said support allowing a vertical displacement of said pin (II) and a projecting part ( 12) disposed on said support (10) and a second portion (2) in which is created a groove (20) and a hole (21) adapted to guide and receive said pin (11), is characterized in that the face upper of said pin (11) has an angle which is at least greater than that presented by said groove and said angle of said pin allowing, when supported by any object of a diameter smaller than that of said hole, on the one hand , to unlock the second portion (2) of the first (1) and secondly, to translate the second portion (2) of the first (1) thereby facilitating its extraction. The way in which the invention can be realized and the advantages which result therefrom will emerge more clearly from the following exemplary embodiments, given by way of non-limiting indication, in support of the appended figures.

La figure 1 présente la vue générale du cadre de l'invention. Dans une forme privilégiée de l'invention, il s'agit de verrouiller une trappe à pile pour un boitier électronique portable grand public d'un format de type calculatrice. La vue présente la trappe à pile déverrouillée et à moitié insérée. On y distingue le picot (11) , la gorge (20) et le trou (21). Figure 1 shows the general view of the scope of the invention. In a preferred form of the invention, it is to lock a battery door for a consumer portable electronic box of a calculator type format. The view shows the battery door unlocked and half-inserted. We distinguish the pin (11), the groove (20) and the hole (21).

La figure 2 est une représentation de la vue de dessous de la trappe à pile (2). La figure 3 est une représentation de la vue de dessus de la trappe à pile La figure 4 présente la vue de dessus du corps (1) du produit. On y voit le détail du picot (1 1 ) positionné sur un support souple (10). La figure 5 présente la vue de dessous du corps (1) du produit. On y voit le détail de la partie saillante (12) positionnée sous le picot (11). Dans une forme privilégiée de l'invention, ce dispositif est prévu pour assembler et désassembler deux parties mécaniques. Par parties mécaniques, au sens de l'invention, il faut comprendre, une première partie représentant le corps du boitier portable. La seconde partie représente une coque, le plus souvent plastique, que l'on dégage pour accéder aux piles, source d'énergie du boitier. Figure 2 is a representation of the bottom view of the battery door (2). Figure 3 is a representation of the top view of the battery door. Figure 4 shows the top view of the body (1) of the product. It shows the detail of the pin (1 1) positioned on a flexible support (10). Figure 5 shows the bottom view of the body (1) of the product. It shows the detail of the protruding part (12) positioned under the pin (11). In a preferred form of the invention, this device is intended to assemble and disassemble two mechanical parts. By mechanical parts, within the meaning of the invention, it is necessary to understand, a first part representing the body of the portable case. The second part represents a shell, usually plastic, that is released to access the batteries, source of energy of the case.

Sur le corps du boitier est positionné un picot qui se présente sous la forme d'une colonnette dont l'extrémité supérieure présente un angle. Cet angle est destiné à faciliter son introduction dans la gorge (20) lors de la fermeture de la trappe à pile. Il est d'ailleurs important que la surface interne de la gorge possède une finition de surface de type polissage afin de ne pas contrecarrer le glissement du picot. Ce picot est positionné sur un support (10) permettant son déplacement vertical. Dans le mode préféré de l'invention, cette particularité permet, lors de l'extraction de la trappe a pile de permettre le dégagement du picot (11) du trou (21). Il est néanmoins essentiel, lors de ce dégagement, de ne pas autoriser un déplacement vertical trop important qui risquerait d'abimer, voir de casser le support (10). A cet effet, il est donc prévu, sous le support (10) de disposer une partie saillante, préférablement positionné en croix qui s'appuiera sur un corps solide , dans notre application, le circuit imprimé, placé en dessous. On the body of the housing is positioned a pin which is in the form of a column whose upper end has an angle. This angle is intended to facilitate its introduction into the groove (20) when closing the battery door. It is also important that the inner surface of the throat has a polishing surface finish so as not to counteract the sliding of the pin. This pin is positioned on a support (10) allowing its vertical movement. In the preferred embodiment of the invention, this feature allows, during the extraction of the battery door to allow the release of the pin (11) of the hole (21). It is nevertheless essential, during this release, not to allow excessive vertical movement that could damage, or break the support (10). For this purpose, it is therefore expected, under the support (10) to have a projecting portion, preferably positioned in a cross which will rely on a solid body, in our application, the printed circuit, placed below.

L'ajustement vertical du circuit imprimé et de la hauteur de cette partie saillante (12) est défini pour permettre un débattement d'une part minium pour dégager le picot et maximum pour protéger l'intégrité du support (10). Lors de l'extraction de la trappe à pile, il suffit donc d'insérer dans le trou (21) un corps d'un diamètre inférieur à celui du trou, en général une pointe de crayon. La pression exercée par ce stylo permettra dans un premier temps de libérer le picot du trou dans lequel il est positionné. Dans un second temps, avec une pression continue du stylo, et grâce à l'angle proposé par le haut du picot, la pointe du stylo va glisser dessus, ce qui aura pour effet de pousser la trappe à pile (2) vers l'extérieur et la dégager suffisamment pour pouvoir être extraite manuellement. De même, lors de la mise en place de la trappe à pile (2), il suffit, après sa mise en place dans les rainures prévues à cet effet dans le corps du boitier (1) de la pousser doucement, ce qui aura pour effet de positionner le picot en face de la gorge (20) aménagée dans la trappe à pile. Les angles de la gorge et du picot sont prévus pour permettre une insertion sans heurts. The vertical adjustment of the printed circuit board and the height of this protruding part (12) is defined to allow a clearance of a small part to release the pin and maximum to protect the integrity of the support (10). When extracting the battery door, it is sufficient to insert into the hole (21) a body of a smaller diameter than the hole, usually a pencil tip. The pressure exerted by this pen will initially release the pin of the hole in which it is positioned. In a second step, with a continuous pressure of the pen, and thanks to the angle proposed by the top of the pin, the tip of the pen will slide on it, which will have the effect of pushing the battery door (2) towards the outside and clear it enough to be manually extracted. Similarly, when setting up the battery door (2), it is sufficient, after its introduction in the grooves provided for this purpose in the body of the housing (1) to push gently, which will have effect of positioning the pin in front of the groove (20) arranged in the battery door. The angles of the groove and the pin are provided to allow a smooth insertion.

D'une manière privilégiée, la surface interne de la gorge est polie afin de faciliter le glissement du picot sur elle. Pendant ce glissement, le corps (10), va se déplacer verticalement sous la pression du picot (11). La position privilégiée du trou (21) dans l'alignement de la gorge permettra de verrouiller le picot, et de la trappe à pile (2), qui remontera verticalement sous la pression exercée maintenant par le support (10). In a preferred manner, the inner surface of the groove is polished to facilitate the sliding of the pin on it. During this sliding, the body (10) will move vertically under the pressure of the pin (11). The preferred position of the hole (21) in the alignment of the groove will lock the pin, and the battery door (2), which will rise vertically under the pressure exerted now by the support (10).
