Definitions
- the present invention relates to molded plastic housings consisting of two half-shells assembled to each other according to a snap-on rim.
- the boxes usually used for example for the protection of electronic circuits, the holding of badges, coins or other pieces of information, comprise a hollow box body closed by a snap-on cover. Examples of such boxes are described in documents US-A-4,915,214, US-A-3,100,567, US-A-4,141,400.
- Document FR-A-2 620 257 also discloses a slot housing for the protection of an information carrier card.
- the housing is formed by bonding or force engagement of two identical half-shells, the engaging surfaces of which include a tenon and a mortise opposite one another with respect to the median axis of penetration of the card.
- Such a structure requires a significant thickness of the side walls of the housing, and does not allow relative engagement of the tenons and mortises over a significant depth.
- this structure does not allow snap-fastening, and the size of a mortise is too small for it to be possible to economically produce by molding removable internal snap-fastening means.
- a first problem proposed by the present invention is to design an economical housing formed of two identical molded half-shells, each comprising a flange with improved engagement means cooperating over an increased height with the engagement means of the flange of the other. half-shell, the engagement means ensuring both self-centering and locking in rotation of the half-shells one on the other, the side walls of the housing being able to have a reduced thickness.
- a second problem proposed by the invention is to design such engagement means further allowing the adaptation of latching means produced by molding and allowing disassembly.
- the invention further aims to provide means for fixing a ring for attaching the housing.
- the fixing means must not protrude from the periphery of the housing, and must not require the opening of the ring for attachment to the housing.
- rebate tenons and the half-mortises have contact faces facing one another which are easily accessible during molding, so that latching means can be produced by molding on these contact faces.
- the flexibility of the tenons and half mortises allows disassembly.
- the rebates of the tenons are oriented towards the outside of the periphery of the half-shell, the half-mortises being hollowed out on the internal face of the rim.
- This arrangement favors a precise execution of latching means, allowing reliable latching.
- latching means it may be advantageous to provide a half-mortise whose wall has a thickness less than or equal to half the total thickness of the corresponding side wall of the half-shell. This facilitates demolding of the half-shell during its manufacturing, and the reproducibility of the shape of the half-mortise latching element is improved, by using inexpensive molds.
- the studs occupy less than half the perimeter of the flange.
- the wall of the rim is deformed to constitute an external housing provided with a half-column generally parallel to the wall of the rim and intended to be assembled axially with a half-column. corresponding to the other half-shell to form a bail for hooking the ring.
- a housing according to the invention is formed by two identical half-shells such as the half-shells 1 and 2 illustrated in FIG. 5.
- Each half-shell such as the half-shell 1 comprises a main wall 3 is connected to a peripheral rim 4.
- the main wall 3 is generally flat, and the peripheral rim 4 is generally perpendicular to the main wall surface 3.
- the half-shell 1 illustrated in FIG. 1 comprises a peripheral flange 4 for obturation provided with two rebated tenons 5 and 6 respectively.
- the tenons 5 and 6 are diametrically opposite one another with respect to the center of the shell, and they extend the rim 4 opposite the main wall 3.
- the peripheral sealing rim 4 further comprises two half mortises 7 and 8 hollowed out in diametrically opposite parts of the rim 4 between the two studs 5 and 6.
- the pins 5 and 6 are shaped and arranged so that they can be accommodated with little play in the half-mortises 7 and 8 of another identical half-shell. In the assembly position, as illustrated in FIG.
- the respective rebates 13 and 14 of the studs 5 and 6 are oriented towards the outside of the periphery of the half-shell, and the half-mortises 7 and 8 are hollowed out on the internal face of the flange 4. L
- the advantage is that, when the case is closed, the tenons and half mortises are invisible from the outside.
- the tenons 5 and 6 occupy less than half the perimeter of the rim 4. The same is true of the half mortises 7 and 8.
- the wall of the rim 4 is deformed to constitute an external housing 15, for example a housing with a cylindrical wall, provided with an outer half-column 16 generally parallel to the wall of the rim 4.
- the half-column 16 is intended to be assembled axially with a half-column corresponding to the other half-shell, to form a bail on which can hang a ring such as the ring 17. It suffices to pass the ring 17 around a half-column 16, before assembling the two half -shells ( Figure 3). After assembly ( Figure 4), the ring 17 is secured to the housing, thanks to the continuity of the two half-columns 16 which join axially by their free end and which are integral at their base with the respective half-shells 1 and 2 .
- each half-shell comprises at least two half-columns diametrically opposite with respect to the center of the half-shell, and two corresponding external housings: thus, in FIG. 1, there is a second external housing 18 and a second half-column 19, diametrically opposite respectively to the first external housing 15 and to the first half-column 16.
- one of the half-columns 16 comprises a central tenon 20, which engages in a corresponding central mortise of the other half-column 19 of another half-shell.
- the housing has a generally circular periphery.
- an even number of tenons and an even number of half mortises can be provided.
- the housing has a square outline, with two pins 5 and 6 in the central position on two opposite sides, and two half mortises 7 and 8 in the central position on the other opposite sides.
- the housing can have a polygonal contour whose number of sides is a multiple of four. At least one tenon is then provided on one side out of two, alternating with half-mortises provided on the sides connecting two sides provided with tenons.
- the tenons comprise, on their outer face, snap ribs or grooves 22, cooperating with snap grooves or ribs 23 corresponding to the inner faces of the corresponding half-mortises.
- snap ribs 23 are provided on the inside faces of the half mortises, and snap grooves 22 are provided on the outside faces of the studs.
- the snap grooves and ribs 22 and 23 have a linear longitudinal profile and a transverse trapezoidal profile. This improves the latching behavior, and reduces the wear resulting from successive latching and dismantling operations.
- tenons and half-mortises makes it possible to provide, in the mold used for making the half-shells, a series of ejectors distributed around the periphery and bearing exclusively on the end edges of the tenons and on the bottom flanges half mortises.
- the ejection traces, placed exclusively on the end edges of the tenons and on the bottom edges of the half-mortises, are thus invisible when the case is closed, and any trace of ejection on the main walls 3 of the housing, allowing for example an embodiment of transparent material.
- breakable shims such as the shim 21 illustrated in FIGS. 1 or 2.
- the breakable shims allow a plate inserted in the housing to be held between the two half-shells.
- the breakable shims of one of the half-shells are then removed, so that the plate bears against the main wall of the first half-shell, and comes to bear on the ends of the breakable shims of the second half-shell.
- the breakable shims 21 can advantageously protrude from the internal face of the main wall 3 of the half-shells.
- the half-shells are oriented so that the pins 5 and 6 of a first half-shell are inserted into the half-mortises 7 and 8 of the other half-shell , and we match the half-columns such as the half-column 16.

Description
La présente invention concerne les boîtiers en matière plastique moulée constitués de deux demi-coques assemblées l'une à l'autre selon un rebord encliquetable.The present invention relates to molded plastic housings consisting of two half-shells assembled to each other according to a snap-on rim.
Les boîtiers habituellement utilisés, par exemple pour la protection de circuits électroniques, la tenue de badges, de pièces de monnaie ou autres éléments d'informations, comprennent un corps de boîtier creux fermé par un couvercle encliquetable. Des exemples de tels boîtiers sont décrits dans les documents US-A-4 915 214, US-A-3 100 567, US-A-4 141 400.The boxes usually used, for example for the protection of electronic circuits, the holding of badges, coins or other pieces of information, comprise a hollow box body closed by a snap-on cover. Examples of such boxes are described in documents US-A-4,915,214, US-A-3,100,567, US-A-4,141,400.
La réalisation d'un tel boîtier nécessite deux moules, l'un pour le corps de boîtier, l'autre pour le couvercle dont la forme diffère de celle du corps de boîtier. L'utilisation de deux moules augmente sensiblement le coût de production d'un tel boîtier.The production of such a case requires two molds, one for the case body, the other for the cover, the shape of which differs from that of the case body. The use of two molds significantly increases the cost of production of such a housing.
On connaît également, par le document FR-A-2 620 257, un boîtier à fente pour la protection d'une carte support d'informations. Le boîtier est formé par collage ou engagement en force de deux demi-coques identiques dont les surfaces engageantes comprennent un tenon et une mortaise opposés l'un à l'autre par rapport à l'axe médian de pénétration de la carte. Une telle structure nécessite une épaisseur importante des parois latérales du boîtier, et ne permet pas un engagement relatif des tenons et mortaises sur une profondeur importante. En outre, cette structure ne permet pas un encliquetage, et la dimension d'une mortaise est trop faible pour que l'on puisse réaliser économiquement par moulage des moyens d'encliquetage intérieurs démontables.Document FR-A-2 620 257 also discloses a slot housing for the protection of an information carrier card. The housing is formed by bonding or force engagement of two identical half-shells, the engaging surfaces of which include a tenon and a mortise opposite one another with respect to the median axis of penetration of the card. Such a structure requires a significant thickness of the side walls of the housing, and does not allow relative engagement of the tenons and mortises over a significant depth. In addition, this structure does not allow snap-fastening, and the size of a mortise is too small for it to be possible to economically produce by molding removable internal snap-fastening means.
Un premier problème proposé par la présente invention est de concevoir un boîtier économique formé de deux demi-coques identiques moulées, comportant chacune un rebord à moyens d'engagement perfectionnés coopérant sur une hauteur accrue avec les moyens d'engagement du rebord de l'autre demi-coque, les moyens d'engagement assurant à la fois un autocentrage et un blocage en rotation des demi-coques l'une sur l'autre, les parois latérales du boîtier pouvant avoir une épaisseur réduite.A first problem proposed by the present invention is to design an economical housing formed of two identical molded half-shells, each comprising a flange with improved engagement means cooperating over an increased height with the engagement means of the flange of the other. half-shell, the engagement means ensuring both self-centering and locking in rotation of the half-shells one on the other, the side walls of the housing being able to have a reduced thickness.
Un second problème proposé par l'invention est de concevoir de tels moyens d'engagement permettant en outre l'adaptation de moyens d'encliquetage réalisés par moulage et autorisant le démontage.A second problem proposed by the invention is to design such engagement means further allowing the adaptation of latching means produced by molding and allowing disassembly.
L'invention vise en outre à prévoir des moyens de fixation d'un anneau d'accrochage du boîtier. Les moyens de fixation ne doivent pas dépasser du pourtour du boîtier, et ne doivent pas nécessiter l'ouverture de l'anneau pour l'accrochage au boîtier.The invention further aims to provide means for fixing a ring for attaching the housing. The fixing means must not protrude from the periphery of the housing, and must not require the opening of the ring for attachment to the housing.
Pour atteindre ces objets ainsi que d'autres, un boîtier selon l'invention est formé d'une première et d'une seconde demi-coques à rebords adaptés pour s'engager l'un sur l'autre, telles que :
- les deux demi-coques sont identiques,
- chaque demi-coque comprend un rebord périphérique d'obturation muni de moyens d'engagement mâles prolongeant le rebord, et de moyens d'engagement femelles creusés dans le rebord de demi-coque à l'opposé des moyens d'engagement mâles, les moyens d'engagement mâles d'une première demi-coque étant conformés et disposés pour se loger à faible jeu dans les moyens d'engagement femelles de la seconde demi-coque,
- les moyens d'engagement mâles d'une demi-coque comprennent au moins deux tenons à feuillures, diamétralement opposés l'un à l'autre par rapport au centre de la demi-coque,
- les moyens d'engagement femelles de ladite demi-coque comprennent au moins deux demi-mortaises, diamétralement opposées l'une à l'autre par rapport au centre de la demi-coque et logées chacune entre deux tenons à feuillures successifs,
- les chants latéraux des tenons à feuillures de la première demi-coque viennent en appui contre les flancs latéraux de la demi-mortaise correspondante de seconde demi-coque.
- the two half-shells are identical,
- each half-shell comprises a peripheral sealing rim provided with male engagement means extending the rim, and female engagement means hollowed out in the half-shell rim opposite the male engagement means, the means male engagement of a first half-shell being shaped and arranged to be housed with little play in the female engagement means of the second half-shell,
- the male engagement means of a half-shell comprise at least two rebate tenons, diametrically opposite one another relative to the center of the half-shell,
- the female engagement means of said half-shell comprise at least two half-mortises, diametrically opposite one another relative to the center of the half-shell and each housed between two tenons with successive rebates,
- the lateral edges of the rebate tenons of the first half-shell bear against the lateral flanks of the corresponding half-mortise of the second half-shell.
On peut profiter du fait que les tenons à feuillures et les demi-mortaises présentent des faces de contact en regard l'une de l'autre qui sont aisément accessibles pendant le moulage, de sorte que des moyens d'encliquetage peuvent être réalisés par moulage sur ces faces de contact. La flexibilité des tenons et demi-mortaises permet le démontage.We can take advantage of the fact that the rebate tenons and the half-mortises have contact faces facing one another which are easily accessible during molding, so that latching means can be produced by molding on these contact faces. The flexibility of the tenons and half mortises allows disassembly.
De préférence, les feuillures des tenons sont orientées vers l'extérieur de la périphérie de demi-coque, les demi-mortaises étant creusées sur la face intérieure du rebord. Cette disposition favorise une exécution précise de moyens d' encliquetage, permettant un encliquetage fiable.Preferably, the rebates of the tenons are oriented towards the outside of the periphery of the half-shell, the half-mortises being hollowed out on the internal face of the rim. This arrangement favors a precise execution of latching means, allowing reliable latching.
En présence de moyens d'encliquetage, on peut trouver avantage à prévoir une demi-mortaise dont la paroi a une épaisseur inférieure ou égale à la moitié de l'épaisseur totale de paroi latérale correspondante de demi-coque. On facilite ainsi le démoulage de la demi-coque lors de sa fabrication, et on améliore la reproductibilité de la forme de l'élément d'encliquetage de la demi-mortaise, en utilisant des moules peu onéreux.In the presence of latching means, it may be advantageous to provide a half-mortise whose wall has a thickness less than or equal to half the total thickness of the corresponding side wall of the half-shell. This facilitates demolding of the half-shell during its manufacturing, and the reproducibility of the shape of the half-mortise latching element is improved, by using inexpensive molds.
Pour réaliser des moyens d'accrochage d'un anneau, les tenons occupent moins de la moitié du périmètre du rebord. Entre un tenon et une demi-mortaise adjacente, la paroi du rebord est déformée pour constituer un logement extérieur muni d'une demi-colonne généralement parallèle à la paroi du rebord et destinée à s'assembler axialement avec une demi-colonne correspondante de l'autre demi-coque pour former une bélière pour accrochage de l'anneau.To make means for attaching a ring, the studs occupy less than half the perimeter of the flange. Between a tenon and an adjacent half-mortise, the wall of the rim is deformed to constitute an external housing provided with a half-column generally parallel to the wall of the rim and intended to be assembled axially with a half-column. corresponding to the other half-shell to form a bail for hooking the ring.

Comme le représentent les figures, un boîtier selon l'invention est formé de deux demi-coques identiques telles que les demi-coques 1 et 2 illustrées sur la figure 5. Chaque demi-coque telle que la demi-coque 1 comprend une paroi principale 3 se raccordant à un rebord périphérique 4. Par exemple, la paroi principale 3 est généralement plane, et le rebord périphérique 4 est généralement perpendiculaire à la surface de paroi principale 3.As shown in the figures, a housing according to the invention is formed by two identical half-shells such as the half-
La demi-coque 1 illustrée sur la figure 1 comprend un rebord périphérique 4 d'obturation muni de deux tenons à feuillure respectivement 5 et 6. Les tenons 5 et 6 sont diamétralement opposés l'un à l'autre par rapport au centre de la coque, et ils prolongent le rebord 4 à l'opposé de la paroi principale 3. Le rebord périphérique d'obturation 4 comprend en outre deux demi-mortaises 7 et 8 creusées dans des parties diamétralement opposées du rebord 4 entre les deux tenons 5 et 6. Les tenons 5 et 6 sont conformés et disposés pour pouvoir se loger à faible jeu dans les demi-mortaises 7 et 8 d'une autre demi-coque identique. En position d'assemblage, comme illustré sur la figure 5, les chants latéraux 9 et 10 de chaque tenon tel que le tenon 7 viennent en appui contre les flancs latéraux 11 et 12 de la demi-mortaise correspondante de l'autre demi-coque, pour assurer le blocage en rotation des deux demi-coques l'une par rapport à l'autre.The half-
Comme illustré sur les figures, les feuillures respectives 13 et 14 des tenons 5 et 6 sont orientées vers l'extérieur de la périphérie de demi-coque, et les demi-mortaises 7 et 8 sont creusées sur la face intérieure du rebord 4. L'avantage est que, lorsque le boîtier est fermé, les tenons et demi-mortaises sont invisibles de l'extérieur.As illustrated in the figures, the
Dans le mode de réalisation représenté sur les figures, les tenons 5 et 6 occupent moins de la moitié du périmètre du rebord 4. Il en est de même des demi-mortaises 7 et 8.In the embodiment shown in the figures, the
Entre un tenon, tel que le tenon 5 de la figure 2 ou le tenon 6 de la figure 1, et une demi-mortaise adjacente telle que la demi-mortaise 8, la paroi du rebord 4 est déformée pour constituer un logement extérieur 15, par exemple un logement à paroi cylindrique, muni d'une demi-colonne 16 extérieure généralement parallèle à la paroi du rebord 4. Comme illustré sur la figure 4, la demi-colonne 16 est destinée à s'assembler axialement avec une demi-colonne correspondante de l'autre demi-coque, pour former une bélière sur laquelle peut s'accrocher un anneau tel que l'anneau 17. Il suffit de passer l'anneau 17 autour d'une demi-colonne 16, avant assemblage des deux demi-coques (figure 3). Après assemblage (figure 4), l'anneau 17 se trouve solidarisé au boîtier, grâce à la continuité des deux demi-colonnes 16 qui se rejoignent axialement par leur extrémité libre et qui sont solidaires à leur base des demi-coques respectives 1 et 2.Between a tenon, such as the
Pour respecter l'identité des deux demi-coques 1 et 2, chaque demi-coque comprend au moins deux demi-colonnes diamétralement opposées par rapport au centre de la demi-coque, et deux logements externes correspondants : ainsi, sur la figure 1, on retrouve un second logement extérieur 18 et une seconde demi-colonne 19, diamétralement opposés respectivement au premier logement extérieur 15 et à la première demi-colonne 16.To respect the identity of the two half-
De préférence, comme illustré sur la figure 4, l'une des demi-colonnes 16 comporte un tenon central 20, qui vient s'engager dans une mortaise centrale correspondante de l'autre demi-colonne 19 d'une autre demi-coque.Preferably, as illustrated in FIG. 4, one of the half-
Dans le mode de réalisation de la figure 1, le boîtier présente une périphérie généralement circulaire. Dans ce cas, on peut prévoir un nombre pair de tenons et un nombre pair de demi-mortaises.In the embodiment of Figure 1, the housing has a generally circular periphery. In this case, an even number of tenons and an even number of half mortises can be provided.
Dans le mode de réalisation de la figure 2, le boîtier présente un contour carré, avec deux tenons 5 et 6 en position centrale sur deux côtés opposés, et deux demi-mortaises 7 et 8 en position centrale sur les autres côtés opposés.In the embodiment of Figure 2, the housing has a square outline, with two
Selon une variante, on peut prévoir deux tenons successifs pour chacun des deux côtés opposés, et deux demi-mortaises correspondantes pour chacun des deux autres côtés opposés.Alternatively, one can provide two successive tenons for each of the two opposite sides, and two corresponding half-mortises for each of the other two opposite sides.
Selon un autre mode de réalisation, le boîtier peut présenter un contour polygonal dont le nombre des côtés est un multiple de quatre. On prévoit alors au moins un tenon sur un côté sur deux, en alternance avec des demi-mortaises prévues sur les côtés reliant deux côtés munis de tenons.According to another embodiment, the housing can have a polygonal contour whose number of sides is a multiple of four. At least one tenon is then provided on one side out of two, alternating with half-mortises provided on the sides connecting two sides provided with tenons.
Dans tous les modes de réalisation, on peut avantageusement prévoir des moyens d'encliquetage sur les faces de contact respectives des tenons et demi-mortaises. Ainsi, dans les modes de réalisation représentés sur les figures, les tenons comportent, sur leur face extérieure, des nervures ou rainures d'encliquetage 22, coopérant avec des rainures ou nervures d'encliquetage 23 correspondantes des faces intérieures des demi-mortaises correspondantes.In all the embodiments, it is advantageous to provide snap-fastening means on the respective contact faces of the tenons and half-mortises. Thus, in the embodiments shown in the figures, the tenons comprise, on their outer face, snap ribs or
De préférence, des nervures d'encliquetage 23 sont prévues sur les faces intérieures des demi-mortaises, et des rainures d'encliquetage 22 sont prévues sur les faces extérieures des tenons. Dans le mode de réalisation avantageux représenté sur les figures, notamment la figure 5, les rainures et nervures d'encliquetage 22 et 23 ont un profil longitudinal linéaire et un profil transversal trapézoïdal. On améliore ainsi la tenue d'encliquetage, et on réduit l'usure résultant des manoeuvres successives d'encliquetage et de démontage.Preferably, snap
La présence des tenons et demi-mortaises permet de prévoir, dans le moule servant à la réalisation des demi-coques, une série d'éjecteurs répartis en périphérie et prenant appui exclusivement sur les chants d'extrémité des tenons et sur les rebords de fond des demi-mortaises. Les traces d'éjection, placées exclusivement sur les chants d'extrémité des tenons et sur les rebords de fond de demi-mortaises, sont ainsi invisibles lorsque le boîtier est fermé, et on évite toute trace d'éjection sur les parois principales 3 du boîtier, permettant par exemple une réalisation en matériau transparent.The presence of tenons and half-mortises makes it possible to provide, in the mold used for making the half-shells, a series of ejectors distributed around the periphery and bearing exclusively on the end edges of the tenons and on the bottom flanges half mortises. The ejection traces, placed exclusively on the end edges of the tenons and on the bottom edges of the half-mortises, are thus invisible when the case is closed, and any trace of ejection on the
Selon un mode de réalisation particulier, on prévoit en outre des cales sécables, telles que la cale 21 illustrée sur les figures 1 ou 2. Les cales sécables permettent la tenue d'une plaque insérée dans le boîtier entre les deux demi-coques. Les cales sécables de l'une des demi-coques sont alors enlevées, de sorte que la plaque vient en appui contre la paroi principale de la première demi-coque, et vient appui sur les extrémités des cales sécables de la seconde demi-coque. Ainsi, les cales sécables 21 peuvent avantageusement dépasser de la face interne de paroi principale 3 des demi-coques.According to a particular embodiment, there are also provided breakable shims, such as the
Pour l'assemblage de deux demi-coques, on oriente les demi-coques de façon que les tenons 5 et 6 d'une première demi-coque viennent s'insérer dans les demi-mortaises 7 et 8 de l'autre demi-coque, et l'on fait correspondre les demi-colonnes telles que la demi-colonne 16.For the assembly of two half-shells, the half-shells are oriented so that the
La présente invention n'est pas limitée aux modes de réalisation qui ont été explicitement décrits, mais elle en inclut les diverses variantes et généralisations contenues dans le domaine des revendications ci-après.The present invention is not limited to the embodiments which have been explicitly described, but it includes the various variants and generalizations thereof contained in the field of claims below.
