Description

PERFECTIONNEMENT POUR MECANISME D'ETUI TOURNANTIMPROVEMENT FOR A ROTATING CASE MECHANISM
La présente invention concerne un mécanisme d'étui tournant du type de ceux utilisés pour des produits cosmétiques, tels que le rouge à lèvres ou diverses crèmes labiales, par exemple.The present invention relates to a rotating case mechanism of the type used for cosmetic products, such as lipstick or various lip creams, for example.
On connaît dans l'art antérieur un grand nombre d'étui tournant comme par exemple celui décrit dans la demande de brevet français n° 97 10166 de la demanderesse. Le principe de ces étuis consiste à obtenir le déplacement axial d'un curseur, porteur du produit, à l'aide de la rotation, par rapport à celui-ci , d'un corps muni d'une rainure interne hélicoïdale dans laquelle vient coopérer un doigt ou téton de guidage du curseur destiné à la parcourir. Ce type de mécanisme nécessite des moyens de blocage en rotation du curseur par rapport au corps pivotant, de manière à provoquer le déplacement axial de celui-ci lorsque la rainure hélicoïdale pivote de façon à être parcourue par le doigt ou téton de guidage du curseur.A large number of rotating cases are known in the prior art, such as that described in French patent application no. 97 10166 by the applicant. The principle of these cases consists in obtaining the axial displacement of a cursor, carrying the product, by means of the rotation, relative to the latter, of a body provided with an internal helical groove in which comes to cooperate. a finger or nipple for guiding the cursor intended to traverse it. This type of mechanism requires means for blocking the rotation of the cursor relative to the pivoting body, so as to cause the axial movement of the latter when the helical groove pivots so as to be traversed by the cursor guide pin or pin.
Ces moyens de blocage peuvent être constitués par une troisième pièce indépendante, comme par exemple, une embase, de laquelle s'étendent deux portions de profils longitudinaux destinés à coopérer avec deux gorges périphériques externes du curseur pour le guider en coulissement et l'immobiliser en rotation par rapport au corps pivotant. Toutefois, ces mécanismes peuvent également ne comporter que deux pièces indépendantes à savoir, un corps pivotant classique et une pièce principale comportant une embase, un curseur et des éléments de charnières articulés, qui les relient, autorisant le mouvement axial de l'un par rapport à l'autre en se dépliant mais empêchant toute rotation entre eux.These locking means can be constituted by a third independent part, such as for example, a base, from which extend two portions of longitudinal profiles intended to cooperate with two external peripheral grooves of the cursor to guide it in sliding and immobilize it in rotation relative to the pivoting body. However, these mechanisms may also include only two independent parts, namely a conventional pivoting body and a main part comprising a base, a slider and articulated hinge elements, which connect them, allowing the axial movement of one relative to the other by unfolding but preventing any rotation between them.
Cependant, de tels dispositifs, s'ils présentent l'avantage de réduire le nombre de pièces nécessaires au mécanisme d'étui tournant, ils comportent néanmoins des inconvénients liés à la fragilité de l'articulation des éléments de charnières entre elles, ainsi qu'à la place qu'ils occupent lorsqu'ils sont en position repliée. La superposition des éléments de charnières au-dessus de l'embase constitue une gène pour respecter les contraintes de dimensionnement de ce type de produits cosmétiques, et ce notamment lorsque pour des raisons esthétiques l'embase choisie est une embase longue.However, such devices, if they have the advantage of reducing the number of parts necessary for the rotating case mechanism, they nevertheless have drawbacks linked to the fragility of the articulation of the hinge elements together, as well as in the place they occupy when in the folded position. The superposition of hinge elements above the base is a gene to comply with the constraints of dimensioning of this type of cosmetics, and in particular when for aesthetic reasons the base is selected a long base.
Ainsi, la présente invention a pour objectif de résoudre les inconvénients précités à l'aide de moyens simples, fiables, peu onéreux et faciles à mettre en œuvre. Elle propose un mécanisme d'étui tournant susceptible d'être utilisé dans la cosmétologie, dont la solidité est importante et dont la taille est réduite, par rapport aux produits similaires de l'art antérieur.Thus, the present invention aims to solve the aforementioned drawbacks using simple, reliable, inexpensive and easy to implement means. It proposes a rotating case mechanism capable of being used in cosmetology, the solidity of which is important and the size of which is reduced, compared with similar products of the prior art.
Selon sa caractéristique principale, le mécanisme d'étui tournant notamment pour produits cosmétiques selon l'invention est constitué par un corps pivotant monté en rotation sur une pièce principale, formée d'un curseur, d'une embase et d'éléments de charnières reliant l'embase au curseur entre un point d'articulation inférieur avec l'embase et un point d'articulation supérieur avec le curseur, ledit curseur étant destiné à être mobile entre une position dépliée ou haute et une position repliée ou basse, et est caractérisé en ce que lorsque le curseur est en position basse, les éléments de charnières sont disposés au moins en partie en dessous du plan horizontal qui contient le point d'articulation inférieur.According to its main characteristic, the rotating case mechanism, in particular for cosmetic products according to the invention, consists of a pivoting body mounted in rotation on a main part, formed of a slider, a base and hinge elements connecting the base to the cursor between a lower articulation point with the base and an upper articulation point with the cursor, said cursor being intended to be movable between an unfolded or high position and a folded or low position, and is characterized in that when the cursor is in the low position, the hinge elements are arranged at least partly below the horizontal plane which contains the lower point of articulation.
Selon une caractéristique complémentaire du mécanisme d'étui tournant, l'embase comporte une enceinte s'étendant en dessous du point d'articulation inférieur, dans laquelle viennent se positionner au moins en partie, les éléments de charnières, lorsque le curseur est en position basseAccording to an additional characteristic of the rotating case mechanism, the base comprises an enclosure extending below the lower point of articulation, in which the hinge elements are positioned at least in part, when the cursor is in position low
Selon un mode de réalisation du mécanisme d'étui tournant, l'enceinte est formée par un alésage de l'embase.According to one embodiment of the turning case mechanism, the enclosure is formed by a bore of the base.
Selon une autre caractéristique du mécanisme d'étui tournant selon l'invention, lorsque le curseur est en position basse, l'ensemble des éléments de charnières sont disposés en dessous du plan horizontal qui contient le point d'articulation inférieur. Selon le mode de réalisation préféré du mécanisme d'étui tournant de l'invention, les éléments de charnières sont constitués par deux éléments, un élément inférieur et un élément supérieur articulés entre eux en un point d'articulation intermédiaire.According to another characteristic of the rotary case mechanism according to the invention, when the cursor is in the low position, all of the hinge elements are arranged below the horizontal plane which contains the lower point of articulation. According to the preferred embodiment of the rotary case mechanism of the invention, the hinge elements consist of two elements, a lower element and an upper element hinged together at an intermediate articulation point.
Par ailleurs, selon une autre caractéristique du mécanisme d'étui tournant, celui-ci est caractérisé en ce que les points d'articulation inférieurs entre l'embase et l'élément inférieur et supérieur, entre le curseur et l'élément supérieur sont disposés de part et d'autre d'un plan longitudinal médian, les éléments inférieur et supérieur étant alignés, lorsque le curseur est en position haute.Furthermore, according to another characteristic of the rotating case mechanism, it is characterized in that the lower articulation points between the base and the lower and upper element, between the slider and the upper element are arranged on either side of a median longitudinal plane, the lower and upper elements being aligned, when the cursor is in the high position.
Selon l'une des variantes d'exécution du mécanisme d'étui tournant, au moins une partie du curseur est disposée sous le plan horizontal qui contient le point d'articulation inférieur, lorsque celui-ci est disposé en position basse ou repliée.According to one of the variant embodiments of the rotating case mechanism, at least part of the slider is arranged under the horizontal plane which contains the lower articulation point, when the latter is placed in the low or folded position.
Selon cette variante d'exécution, le curseur comporte dans sa partie inférieure une encoche de dégagement dans laquelle vient se positionner en partie, l'un des éléments de charnières, lorsque le mécanisme est en position basse ou repliée.According to this alternative embodiment, the cursor comprises in its lower part a release notch in which is partially positioned, one of the hinge elements, when the mechanism is in the low position or folded.

Selon ce mode de réalisation, les surfaces de butée sont disposées dans des rainures internes du corps pivotant à leurs extrémités respectives. Selon une autre caractéristique de ce mode de réalisation, les moyens d'arrêt présentent des surfaces d'appui et de butée latérales qui empêchent la rotation entre le curseur et le corps pivotant dans les positions extrêmes du curseur repliée et dépliée et des surfaces d'appui et de butée longitudinales qui empêchent tout mouvement longitudinal du curseur dans le corps pivotant lorsqu'il est en position dépliée.According to this embodiment, the abutment surfaces are arranged in internal grooves of the pivoting body at their respective ends. According to another characteristic of this embodiment, the stop means have lateral bearing and abutment surfaces which prevent rotation between the cursor and the pivoting body in the extreme positions of the folded and unfolded cursor and the surfaces of longitudinal support and stop which prevent any longitudinal movement of the cursor in the pivoting body when it is in the unfolded position.

Les figures 14a, 14b et 14c illustrent en coupe respectivement selon DD, EE et FF l'agencement des éléments de butée du corps pivotant. Selon l'invention, le mécanisme d'étui tournant portant la référence générale (1) est constitué par deux pièces, à savoir, un corps pivotant (2) et une pièce principale (3). La pièce principale est constituée d'une embase (4), d'un curseur (5) et d'éléments de charnières articulés (6) également appelés nervures qui les relient et qui constituent les moyens de blocage en rotation, destinés à solidariser le curseur et l'embase pour empêcher tout pivotement respectif entre eux.Figures 14a, 14b and 14c illustrate in section respectively according to DD, EE and FF the arrangement of the abutment elements of the pivoting body. According to the invention, the turning case mechanism bearing the general reference (1) consists of two parts, namely, a pivoting body (2) and a main piece (3). The main part is constituted of a base (4), a slider (5) and articulated hinge elements (6) also called ribs that connect them and that constitute the rotational locking means, for securing the slider and base to prevent any respective pivoting between them.
L'embase (4) et le curseur (5) sont bloqués en rotation respectivement entre eux par les éléments de charnières (6), lesdits éléments permettant ainsi au curseur (5) de se déplacer axialement par rapport à l'embase (4), de manière connue en soi le long de l'axe de révolution (ZZ') du mécanisme d'étui tournant (1).The base (4) and the slider (5) are locked in rotation respectively between them by the hinge elements (6), said elements thus allowing the slider (5) to move axially relative to the base (4) , in a manner known per se along the axis of revolution (ZZ ') of the rotary case mechanism (1).
Le déplacement axial du curseur (5) par rapport à l'embase (4) est obtenu de manière connue en soi par la rotation du corps pivotant (2) par rapport à la pièce principale (3), qui permet à un ou plusieurs tétons de guidage (7a, 7b) du curseur (5) de parcourir des rainures internes (8a, 8b) respectives disposées sur la paroi interne du corps pivotant (2), lors de son pivotement.The axial displacement of the cursor (5) relative to the base (4) is obtained in a manner known per se by the rotation of the pivoting body (2) relative to the main part (3), which allows one or more studs guide (7a, 7b) of the cursor (5) to traverse respective internal grooves (8a, 8b) disposed on the internal wall of the pivoting body (2), during its pivoting.
Notons que ce type de mécanisme d'étui tournant (1) peut avantageusement être utilisé pour réaliser des tubes de rouge à lèvres ou autres produits cosmétiques ou pharmaceutiques, tels que des crèmes labiales. Toutefois, ces mécanismes pourraient éventuellement être utilisés dans d'autres domaines, comme par exemple, pour réaliser les colles en tube ou autre.Note that this type of rotating case mechanism (1) can advantageously be used to make lipstick tubes or other cosmetic or pharmaceutical products, such as lip creams. However, these mechanisms could possibly be used in other fields, such as, for example, for making tube or other adhesives.
Les éléments de charnières (6) sont articulés à leur extrémité supérieure sur la face inférieure du curseur (5) et à leur extrémité inférieure sur l'extrémité supérieure de l'embase (4), respectivement aux points d'articulation supérieur et inférieur (9a, 9b). Ils permettent au curseur (5) de coulisser le long de l'axe de révolution (ZZ'), à l'intérieur du corps pivotant (2) entre une position repliée (A) ou position basse, illustrée figure 2 et une position dépliée (B) ou position haute, telle qu'illustrée figures la et 3. Selon l'invention, le mécanisme d'étui tournant (1) est réalisé de manière à ce qu'en position repliée (A), appelée également position basse, les éléments de charnières (6) soient disposés au moins en partie en dessous du plan horizontal (H) qui contient le point d'articulation inférieur (9b) desdits éléments charnières (6) sur l'embase (4).The hinge elements (6) are articulated at their upper end on the lower face of the slider (5) and at their lower end on the upper end of the base (4), respectively at the upper and lower articulation points ( 9a, 9b). They allow the cursor (5) to slide along the axis of revolution (ZZ '), inside the pivoting body (2) between a folded position (A) or low position, illustrated in Figure 2 and an unfolded position (B) or high position, as illustrated in Figures la and 3. According to the invention, the rotary case mechanism (1) is designed so that in the folded position (A), also called the low position, the hinge elements (6) are arranged at least partially below the horizontal plane (H) which contains the lower articulation point (9b) of said hinge elements (6) on the base (4).
Selon le mode de réalisation préféré du mécanisme d'étui tournant (1) ; lorsqu'ils sont en position repliée (A) ou position basse, les éléments de charnières (6) sont disposés entièrement en dessous du point d'articulation inférieur (9b). Pour ce faire, l'embase (4) est munie à son extrémité supérieure d'une enceinte ou logement (10), dans laquelle sont destinées à se positionner les éléments de charnières, ladite enceinte s'étendant en dessous du point d'articulation inférieur (9b). Cette enceinte (10) peut avantageusement être obtenue en réalisant un alésage (11) de l'embase (4) sur la longueur de celle-ci.According to the preferred embodiment of the rotating case mechanism (1); when in the folded position (A) or the low position, the hinge elements (6) are arranged entirely below the lower articulation point (9b). To do this, the base (4) is provided at its upper end with an enclosure or housing (10), in which the hinge elements are intended to be positioned, said enclosure extending below the point of articulation. lower (9b). This enclosure (10) can advantageously be obtained by making a bore (11) of the base (4) over the length of the latter.
Selon le mode de réalisation préféré du mécanisme d'étui tournant (1), selon l'invention, la pièce principale (1) comporte deux éléments de charnières ou nervures (6a, 6b) articulés entre eux en un point d'articulation intermédiaire (9c). Le premier élément ou élément inférieur (6b) est articulé sur le sommet de l'embase (4) au point d'articulation inférieur (9b) et l'élément supérieur (6a) est articulé sur la face inférieure (13) du fond (5b) du curseur (5). Les différentes articulations (9a, 9b, 9c) sont avantageusement obtenues, de manière connue en soi, par des rétrécissements ou étranglements des portions de paroi constituant les éléments charnières (6a, 6b). Notons que selon les différents modes de réalisation du mécanisme d'étui tournant selon l'invention, les pièces le composant sont avantageusement réalisées en matière plastique à l'aide d'un procédé d'injection par exemple.According to the preferred embodiment of the rotary case mechanism (1), according to the invention, the main part (1) comprises two hinge elements or ribs (6a, 6b) articulated together at an intermediate point of articulation ( 9c). The first element or lower element (6b) is articulated on the top of the base (4) at the lower articulation point (9b) and the upper element (6a) is articulated on the lower face (13) of the bottom ( 5b) of the cursor (5). The various joints (9a, 9b, 9c) are advantageously obtained, in a manner known per se, by narrowing or constrictions of the wall portions constituting the hinge elements (6a, 6b). Note that according to various embodiments of the turning case mechanism according to the invention, parts of it are advantageously made of plastic using an injection method, for example.
Comme le montrent les figures lb et 3, les éléments de charnières supérieurs et inférieurs sont disposés dans le prolongement l'un de l'autre, lorsque le mécanisme d'étui tournant (1) est en position dépliée ou position haute (B). Notons que les points d'articulation supérieur (9a) et inférieur (9b) sont disposés avantageusement de part et d'autre d'un plan longitudinal médian contenant l'axe de révolution (ZZ') du mécanisme. Il va de soi que la configuration des éléments de charnières pourrait être différente sans pour autant sortir du champ de protection de l'invention.As shown in Figures lb and 3, the elements of upper and lower hinges are arranged in the extension one of the other, when the turning case mechanism (1) is in unfolded position or high position (B). Note that the upper (9a) and lower (9b) points of articulation are advantageously arranged on either side of a median longitudinal plane containing the axis of revolution (ZZ ') of the mechanism. It goes without saying that the configuration of the hinge elements could be different without departing from the scope of protection of the invention.
Selon le mode de réalisation préféré de l'invention, l'ensemble des éléments de charnières (6a, 6b) vient se loger sous le point d'articulation inférieur (9b) lorsque le mécanisme se trouve en position basse (A). L'élément de charnières inférieur (6b) vient préférentiellement se positionner de manière sensiblement verticale, parallèlement à la paroi de l'alésage (11) à l'aplomb du point d'articulation inférieur (9b), l'élément de charnières supérieure (6a) étant légèrement incliné comme le montre la figure 5 entre le point d'articulation intermédiaire (9c) et le point d'articulation supérieur (9a) situé légèrement au-dessus dudit point intermédiaire (9c).According to the preferred embodiment of the invention, all of the hinge elements (6a, 6b) are housed under the lower articulation point (9b) when the mechanism is in the low position (A). The lower hinge element (6b) is preferably positioned substantially vertically, parallel to the wall of the bore (11) perpendicular to the lower articulation point (9b), the upper hinge element ( 6a) being slightly inclined as shown in FIG. 5 between the intermediate articulation point (9c) and the upper articulation point (9a) situated slightly above said intermediate point (9c).
Selon le mode de réalisation illustré, lorsque le mécanisme d'étui tournant est en position basse ou repliée (A), une partie du curseur (5) destiné à recevoir le produit est disposée dans le logement (10) de l'embase (4) avantageusement en dessous du plan horizontal (H), qui contient le point d'articulation inférieur (9b). Notons toutefois que selon une variante d'exécution, ledit point d'articulation inférieur pourrait être situé en dessous du sommet de l'embase à l'intérieur du logement de ladite embase.According to the illustrated embodiment, when the rotating case mechanism is in the low or folded position (A), part of the slider (5) intended to receive the product is placed in the housing (10) of the base (4 ) advantageously below the horizontal plane (H), which contains the lower articulation point (9b). Note however that according to an alternative embodiment, said lower articulation point could be located below the top of the base inside the housing of said base.
Le curseur (5) est de manière connue en soi, constitué par une portion de tube (5a) obturée à son extrémité inférieure par une paroi circulaire ou fond (5b). Il présente avantageusement un décrochement ou encoche de dégagement (12) dans sa partie inférieure, c'est à dire un évidement d'une partie de la portion de tube périphérique (5a) et du fond (5b) tel que le montre la figure 4, ladite encoche étant destinée à faciliter son positionnement à l'intérieur de l'alésage (11) de l'embase (4).The cursor (5) is in a manner known per se, constituted by a portion of tube (5a) closed at its lower end by a circular wall or bottom (5b). It advantageously has a recess or release notch (12) in its lower part, that is to say a recess of a part of the portion of peripheral tube (5a) and of the bottom (5b) as shown in FIG. 4 , said notch being intended to facilitate its positioning inside the bore (11) of the base (4).
En effet, cette encoche de dégagement (12) est positionnée sur le curseur (5) de la pièce principale (2) dans sa partie inférieure, de manière à ce que lorsque ladite partie se positionne dans le logement (10) de l'embase (4), elle ne soit pas gênée par la présence de l'élément de charnières inférieur (6b), celui-ci venant se positionner dans l'encoche ainsi prévue comme le montre la figure 5. Il est important de noter que lorsque le mécanisme d'étui tournant (1) est en position basse ou repliée, le point d'articulation supérieur (9a) entre le curseur (5) et les éléments de charnières (6, 6a, 6b) se situe en dessous du point d'articulation inférieur (9b) entre lesdits éléments et l'embase (4).Indeed, this release notch (12) is positioned on the slider (5) of the main part (2) in its lower part, so that when said part is positioned in the housing (10) of the base (4) it is not hampered by the presence of the element of lower hinges (6b) thereof from position themselves in the notch thus provided as shown in Figure 5. It is important to note that when the rotary case mechanism (1) is in the low or folded position, the upper articulation point (9a) between the cursor (5) and the hinge elements (6, 6a, 6b) is located below the lower point of articulation (9b) between said elements and the base (4).
De plus, les éléments de charnières (6, 6a, 6b) du mécanisme d'étui tournant (1) comportent avantageusement un orifice de remplissage (15) réalisé en deux parties, une partie sur chacun des éléments de charnières (6a, 6b), comme le montrent les figures 5 et 6. Ledit orifice (15), ainsi que l'évidement (12) du fond (5b) du curseur sont destinés à permettre le remplissage en produit dudit curseur par l'arrière du mécanisme, c'est à dire au travers de l'alésage (11) de l'embase (4).In addition, the hinge elements (6, 6a, 6b) of the rotary case mechanism (1) advantageously include a filling orifice (15) made in two parts, one part on each of the hinge elements (6a, 6b). , as shown in FIGS. 5 and 6. Said orifice (15), as well as the recess (12) in the bottom (5b) of the slider are intended to allow the filling of the said slider with product from the rear of the mechanism, it is to say through the bore (11) of the base (4).
Selon le mode de réalisation illustré, le corps pivotant (2) est destiné à être clipé sur l'embase (4) de la pièce principale (3), ladite embase présentant à son extrémité supérieure, une rainure de clipage (14). Notons que cette rainure (14) permet de réaliser l'articulation en rotation entre la pièce principale (3) et le corps pivotant (2), il va de soi que le montage et l'articulation entre le corps pivotant et l'embase pourraient être obtenus de manière différente, sans la rainure de clipage par exemple, sans pour autant sortir du champs de protection de l'invention. . Par ailleurs, notons que le corps pivotant (2) comporte deux rainures hélicoïdales (8a, 8b) situées dans sa paroi périphérique interne, de manière diamétralement opposées. Ces rainures sont destinées à coopérer avec deux tétons de guidage (7a, 7b) disposés, de manière diamétralement opposée, sur la portion de tube (5a) formant le curseur (5) sensiblement au niveau de l'extrémité supérieure de celui-ci comme le montre la figure 7a. Il va de soi que la configuration des moyens de coopération entre les deux pièces complémentaires, à savoir, la pièce principale et le corps pivotant pourrait être différente et ne présenter qu'une rainure et un téton par exemple, sans pour autant sortir du champ de protection de l'invention.According to the illustrated embodiment, the pivoting body (2) is intended to be clipped onto the base (4) of the main part (3), said base having at its upper end, a clipping groove (14). Note that this groove (14) makes it possible to produce the articulation in rotation between the main part (3) and the pivoting body (2), it goes without saying that the mounting and the articulation between the pivoting body and the base could be obtained differently, without the clipping groove for example, without departing from the protective fields of the invention. . Furthermore, note that the pivoting body (2) has two helical grooves (8a, 8b) located in its inner peripheral wall, diametrically opposite. These grooves are intended to cooperate with two guide pins (7a, 7b) arranged, in diametrically opposite manner, on the portion of tube (5a) forming the cursor (5) substantially at the upper end thereof as shown in Figure 7a. It goes without saying that the configuration of the means of cooperation between the two complementary parts, namely, the main part and the pivoting body could be different and present only a groove and a stud for example, without going beyond the scope protection of the invention.
Selon une variante d'exécution du premier mode de réalisation précédemment décrit où les pièces similaires par leur fonction portent les mêmes références, le mécanisme d'étui tournant présente des moyens d'arrêt (20a, 20b, 20c, 21a, 21b, 21c) destinés à empêcher le mouvement du curseur (5) au delà de ses positions extrêmes repliée et déployée. Ces moyens d'arrêt sont constitués par la coopération entre des surfaces de butée (20a, 20b, 20c) du corps pivotant et des surfaces d'appui (21a, 21b, 21c) du curseur (5) de la pièce principale (3).According to an alternative embodiment of the first embodiment described above where the parts similar in function have the same references, the rotary case mechanism has means stop (20a, 20b, 20c, 21a, 21b, 21c) for preventing movement of the cursor (5) beyond its extreme folded and deployed positions. These stop means are constituted by the cooperation between abutment surfaces (20a, 20b, 20c) of the pivoting body and bearing surfaces (21a, 21b, 21c) of the slider (5) of the main part (3) .
Les surfaces d'appui (21a, 21b, 21c) sont avantageusement disposées sur les tétons de guidage (7a, 7b) du curseur tandis que les surfaces de butée (20a, 20b, 20c) sont disposées aux extrémités respectives des rainures internes hélicoïdales (8a, 8b) du corps pivotant. Selon cette variante d'exécution, les moyens d'arrêts comportent :The bearing surfaces (21a, 21b, 21c) are advantageously arranged on the guide pins (7a, 7b) of the slider while the abutment surfaces (20a, 20b, 20c) are arranged at the respective ends of the helical internal grooves ( 8a, 8b) of the pivoting body. According to this variant, the stop means include:
- des surfaces d'appui et de butée latérales (20a, 20b, 21a, 21b) destinés à empêcher la rotation respective entre le corps pivotant (2) et le curseur (5).- the bearing surfaces and lateral abutment (20a, 20b, 21a, 21b) for preventing the relative rotation between the pivoting body (2) and the slider (5).
- des surfaces d'appui et de butée longitudinales (20c, 21c) qui empêchent tout mouvement longitudinal en position dépliée entre le curseur et le corps pivotant.- the bearing surfaces and longitudinal abutment (20c, 21c) that prevent any longitudinal movement in the unfolded position between the slider and the pivoting body.
Les surfaces d'appuis et de butée latérales (20a, 20b, 21a, 21b) présentent avantageusement un angle (E, F) non nul avec le rayon respectif du corps pivotant ou du curseur comme le montrent les figures 12c, 14a et 14c. Les surfaces d'appuis (20a, 20b) sont avantageusement formées par les bords latéraux des tétons de guidage (7a, 7b) qui sont biseautés pour venir se verrouiller sur les surfaces de butée (21a, 21b) des extrémités des rainures (8a, 8b) à la manière de harpons pour empêcher la sortie des tétons de leurs rainures lorsque le corps pivotant est forcé en rotation. Selon la variante d'exécution illustrée figure 12b et 14b, les surfaces d'appuis et de butée longitudinales (20c, 21c) présentent un angle (G) non nul avec le plan transversal horizontal. Il va de soi que les surfaces de butée et d'appui pourraient présenter une configuration différente et n'être plus situées sur les tétons de guidage et les rainures sans pour autant sortir du champs de protection de l'invention.The lateral bearing and abutment surfaces (20a, 20b, 21a, 21b) advantageously have a non-zero angle (E, F) with the respective radius of the pivoting body or of the slider as shown in FIGS. 12c, 14a and 14c. The bearing surfaces (20a, 20b) are advantageously formed by the lateral edges of the guide pins (7a, 7b) which are bevelled to come to lock on the abutment surfaces (21a, 21b) of the ends of the grooves (8a, 8b) like harpoons to prevent the nipples from coming out of their grooves when the pivoting body is forced into rotation. According to the alternative embodiment illustrated in FIG. 12b and 14b, the longitudinal support and abutment surfaces (20c, 21c) have a non-zero angle (G) with the horizontal transverse plane. It goes without saying that the abutment and bearing surfaces could have a different configuration and no longer be located on the guide pins and the grooves without departing from the protective fields of the invention.
Selon l'invention et afin de permettre un agencement optimal des éléments de charnière (6a, 6b) dans le logement (10) de l'embase (4) lorsque le mécanisme se retrouve en position repliée comme le montre la figure 10a, l'élément de charnière inférieure (6b) présente un profil transversal arrondi ou galbé tel qu'illustré figure 11b. Selon la variante d'exécution illustrée figures 10a à 11b, les deux éléments de charnières (6a, 6b) ont un profil transversal galbé ; de plus lorsque le curseur se trouve en position basse, on peut noter que l'élément de charnière supérieur (6a) est disposé sensiblement dans un plan transversal horizontal, dans un logement (24) prévu dans la paroi inférieure (5b) du curseur (5) tandis que l'élément de charnière inférieure (6b) vient se positionner dans l'encoche de dégagement (12) du curseur dans une position verticale.According to the invention and in order to allow an optimal arrangement of the hinge elements (6a, 6b) in the housing (10) of the base (4) when the mechanism is found in the folded position as shown FIG. 10a, the lower hinge element (6b) has a rounded or curved transverse profile as illustrated in FIG. 11b. According to the alternative embodiment illustrated in Figures 10a to 11b, the two hinge elements (6a, 6b) have a curved transverse profile; moreover, when the cursor is in the low position, it can be noted that the upper hinge element (6a) is disposed substantially in a horizontal transverse plane, in a housing (24) provided in the lower wall (5b) of the cursor ( 5) while the lower hinge element (6b) is positioned in the release notch (12) of the cursor in a vertical position.
Notons que l'élément de charnière inférieure (6b) présente un diamètre extérieur égal au jeu près au diamètre intérieur de l'alésage (11) de l'embase (4) tandis que l'élément de charnière supérieure (6a) présente un diamètre extérieur et des dimensions qui permettent son passage dans le diamètre intérieur de la collerette de l'embase. Notons que le profil arrondi ou galbé des éléments de charnière constitue un moyen de rigidification des éléments de charnière destinés à leur conférer une plus grande résistance en torsion.Note that the lower hinge element (6b) has an outer diameter equal to the clearance close to the inner diameter of the bore (11) of the base (4) while the upper hinge element (6a) has a diameter outside and dimensions which allow its passage in the inside diameter of the collar of the base. Note that the rounded or curved profile of the hinge elements constitutes a means of stiffening the hinge elements intended to give them greater resistance to torsion.
Selon l'invention, la pièce principale (3) est avantageusement réalisée en matière plastique, ladite matière étant choisie entre les polyoléfines tel que le polypropylène ou le polyéthylène et les acétaliques tel que le polyoxyméthylène. Il va de soi que l'on pourrait utiliser d'autres matériaux ou d'autres matières plastiques pour réaliser le mécanisme d'étui tournant de l'invention.According to the invention, the main part (3) is advantageously made of plastic, said material being chosen from polyolefins such as polypropylene or polyethylene and acetals such as polyoxymethylene. It goes without saying that one could use other materials or other plastics to produce the rotary case mechanism of the invention.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés à titre d'exemples, mais elle comprend aussi tous les équivalents techniques ainsi que leurs combinaisons. Of course, the invention is not limited to the embodiments described and shown by way of examples, but it also includes all the technical equivalents and their combinations.
