Description

La présente invention concerne un dispositif support permettant de maintenir des pièces creuses dans une position déterminée, ainsi qu'un procédé de mise en oeuvre d'un tel dispositif.The present invention relates to a support device for maintain hollow parts in a determined position, as well as a method of implementing such a device.

L'invention trouve une application particulièrement avantageuse, mais non exclusive, dans le domaine du traitement de surface externe de pièces creuses.The invention finds a particularly advantageous application, but not exclusive, in the field of external surface treatment of hollow parts.

Dans l'industrie, il est courant de traiter la surface externe de pièces creuses afin d'en modifier l'aspect extérieur. On pense, par exemple, à des opérations de brillantage ou d'anodisation par voie chimique ou électrochimique de pièces métalliques, mais également à des opérations de métallisation ou de coloration par trempage ou pulvérisation de pièces en matière plastique. Lorsqu'elles présentent des dimensions relativement petites, les pièces sont, de préférence, traitées en grand nombre. Pour cela on utilise généralement un dispositif support capable d'immobiliser individuellement chacune des pièces creuses, en réalisant un maintien interne de nature à libérer toute la surface externe.In industry, it is common to treat the external surface of parts hollow in order to modify its external appearance. We think, for example, of polishing or anodizing operations by chemical means or electrochemical of metal parts, but also to operations of metallization or coloring by dipping or spraying of plastic material. When they have relatively large dimensions small, parts are preferably processed in large numbers. For it we generally use a support device capable of immobilizing individually each of the hollow parts, making a hold internal so as to release the entire external surface.

Dans la pratique, les pièces creuses sont généralement préparées préalablement à l'opération de traitement de surface proprement dite. Une telle préparation peut par exemple consister en un trempage dans un bain de dégraissage, suivi d'un trempage dans un bain de rinçage. Quoi qu'il en soit, le dispositif support doit pouvoir remplir durablement sa fonction tout au long des différentes phases du traitement de surface envisagé. Il doit également être en mesure d'assurer le maintien individuel de chaque pièce creuse quelle que soit sa position dans l'espace, afin de permettre toutes libertés de manipulation.In practice, hollow parts are generally prepared prior to the actual surface treatment operation. A such preparation may for example consist of soaking in a bath degreasing, followed by soaking in a rinsing bath. Anyway either, the support device must be able to fulfill its function durably throughout the various phases of the surface treatment envisaged. he must also be able to ensure the individual maintenance of each hollow part whatever its position in space, in order to allow all freedom of manipulation.

On connaít notamment, de l'état de la technique, un dispositif support comportant un cadre porteur sur lequel sont fixés une multitude d'organes de maintien déformants. Chaque organe de maintien est constitué par une pièce en U dont la partie centrale est solidarisée au cadre porteur et dont les deux branches sensiblement parallèles sont aptes à être sollicitées en écartement l'une par rapport à l'autre grâce au caractère déformable de l'ensemble. Afin de permettre la mise en place des pièces creuses, le dispositif de l'art antérieur prévoit par ailleurs des moyens de libérations permettant de rapprocher les deux branches de l'organe de maintien.We know in particular, from the state of the art, a device support comprising a support frame on which are fixed a multitude deforming holding members. Each holding member is consisting of a U-shaped part, the central part of which is secured to the frame carrier and whose two substantially parallel branches are capable of being requested in separation from one another thanks to the character deformable of the whole. To allow the installation of parts hollow, the device of the prior art also provides means for releases allowing to bring the two branches of the organ of maintenance.

Ce type de dispositif support présente toutefois l'inconvénient de ne pas permettre un désengagement aisé des pièces creuses. Les organes de maintien sont en effet difficilement accessibles lorsque les pièces creuses sont insérées dessus. Les deux branches du U, c'est-à-dire les deux parties mobiles de chaque organe de maintien, sont ainsi particulièrement difficiles à manipuler.However, this type of support device has the disadvantage of do not allow easy disengagement of hollow parts. Organs are indeed difficult to access when the parts hollow are inserted on it. The two branches of the U, i.e. the two moving parts of each holding member, are thus particularly difficult to handle.

Aussi le problème technique à résoudre, par l'objet de la présente invention, est de proposer un dispositif support comportant un cadre porteur sur lequel est fixé au moins un organe de maintien déformable destiné à immobiliser une pièce creuse devant subir un traitement de surface externe, dispositif support qui permettrait d'éviter les problèmes de l'état de la technique en offrant notamment une grande facilité de mise en oeuvre au niveau de chacun de ses organes de maintien. Also the technical problem to be solved, by the subject of this invention is to provide a support device comprising a frame carrier on which is fixed at least one deformable holding member intended to immobilize a hollow part which must undergo a treatment of external surface, support device which would avoid problems of the state of the art, in particular offering great ease of installation implemented at the level of each of its holding members.

La solution au problème technique posé consiste, selon la présente invention, en ce que chaque organe de maintien comporte une partie statique solidaire du cadre porteur, ainsi qu'une partie montée élastiquement mobile en écartement par rapport à la partie statique entre, d'une part, une position resserrée dans laquelle la pièce creuse est apte à être insérée au moins partiellement sur la partie statique et sur la partie mobile, et d'autre part, une position libérée dans laquelle la pièce creuse est apte à être bloquée par l'organe de maintien sous l'action de la force de pression exercée par la partie mobile qui est sollicitée élastiquement en éloignement par rapport à la partie statique qui forme butée.The solution to the technical problem posed consists, according to this invention, in that each holding member comprises a part static integral with the supporting frame, as well as a mounted part elastically mobile in spacing from the static part between, on the one hand, a tight position in which the hollow part is capable of be inserted at least partially on the static part and on the part mobile, and on the other hand, a released position in which the part digs is able to be blocked by the holding member under the action of the force of pressure exerted by the movable part which is elastically stressed in distance from the static part which forms a stop.

A la différence de son homologue de l'état de la technique, chaque organe de maintien conforme à l'invention ne comporte qu'une seule partie mobile, qui plus est montée élastiquement mobile en écartement par rapport à la partie statique, et non pas par rapport à une autre partie mobile. Une autre différence structurelle réside dans le fait que la pièce à traiter est ici insérée à la fois sur la partie statique et sur la partie mobile, mais pas sur deux parties mobiles comme dans l'art antérieur. La pièce creuse est ainsi bloquée par l'action combinée, de la force de pression exercée par l'unique partie mobile, et du rôle de butée rempli par la partie statique.Unlike its prior art counterpart, each holding member according to the invention has only one mobile part, which is moreover mounted elastically mobile in spacing by with respect to the static part, not with respect to another part mobile. Another structural difference is that the part to be process is here inserted both on the static part and on the mobile part, but not on two moving parts as in the prior art. The room hollow is thus blocked by the combined action of the pressing force exercised by the single movable part, and the role of stopper filled by the part static.

L'invention telle qu'ainsi définie présente l'avantage d'offrir une mise en oeuvre sensiblement améliorée par rapport au dispositif support de l'art antérieur. Chaque organe de maintien ne comporte en effet qu'une unique partie mobile à manipuler. Par ailleurs, la configuration structurelle de chaque organe de maintien n'impose pas que l'extrémité libre de la partie mobile s'étende vers l'intérieur de la pièce creuse. Cela sous-entend que la partie mobile en question, et notamment son extrémité libre, est particulièrement accessible. The invention as defined has the advantage of offering a implementation significantly improved compared to the support device of the prior art. Each holding member in fact comprises only one only mobile part to handle. Furthermore, the configuration structural of each holding member does not require that the end free of the movable part extends towards the interior of the hollow part. it implies that the mobile part in question, and in particular its end free, is particularly accessible.

La présente invention concerne également les caractéristiques qui ressortiront au cours de la description qui va suivre, et qui devront être considérées isolément ou selon toutes leurs combinaisons techniques possibles.The present invention also relates to the features which will emerge during the description which follows, and which should be considered in isolation or in all their technical combinations possible.

Cette description donnée à titre d'exemple non limitatif, fera mieux comprendre comment l'invention peut être réalisée, en référence aux dessins annexés sur lesquels :

  • La figure 1 est une vue en perspective illustrant un dispositif support conforme à l'invention.
  • La figure 2 montre en perspective des moyens de libération destinés à être intégrés au dispositif support de la figure 1.
  • La figure 3 constitue une vue en perspective représentant la coopération entre le dispositif support de la figure 1 et les moyens de libération de la figure 2, pendant la phase de mise en place des pièces creuses.
  • La figure 4 est une vue similaire à celle de la figure 3, mais correspondant à la phase de maintien.
    • This description given by way of nonlimiting example will make it easier to understand how the invention can be implemented, with reference to the attached drawings in which:
  • Figure 1 is a perspective view illustrating a support device according to the invention.
  • FIG. 2 shows in perspective release means intended to be integrated into the support device of FIG. 1.
  • Figure 3 is a perspective view showing the cooperation between the support device of Figure 1 and the release means of Figure 2, during the placement phase of the hollow parts.
  • Figure 4 is a view similar to that of Figure 3, but corresponding to the holding phase.

    • La figure 1 illustre un dispositif support (1) comportant un cadre porteur (10) sur lequel est solidarisée une pluralité d'organes de maintien (20) destinés à immobiliser par l'intérieur des pièces creuses (100) devant subir un traitement de surface externe. Figure 1 illustrates a support device (1) comprising a frame carrier (10) on which is secured a plurality of holding members (20) intended to immobilize hollow parts inside (100) in front undergo an external surface treatment.

    Conformément à l'objet de la présente invention, chaque organe de maintien (20) comporte une partie statique (21) solidaire du cadre porteur (10), et une partie (22) montée élastiquement mobile en écartement par rapport à la partie statique (21). La partie mobile (22) est ainsi apte à être déplacée entre une position resserrée et une position libérée permettant respectivement l'insertion et l'immobilisation d'une pièce creuse (100). Concrètement, lorsque la partie mobile (22) est en position resserrée, la pièce creuse (100) peut être insérée à la fois sur au moins une portion de la partie statique (21) et sur au moins une portion de la partie mobile (22). Mais quand la partie mobile (22) est en position libérée, la pièce creuse (100) est dans ce cas là en mesure d'être bloquée par l'organe de maintien (20), sous l'action de la force de pression exercée par la partie mobile (22) qui est sollicitée élastiquement en éloignement par rapport à la partie statique (21) qui forme alors butée.In accordance with the object of the present invention, each member of holding (20) comprises a static part (21) integral with the support frame (10), and a part (22) mounted elastically mobile in spacing by relative to the static part (21). The movable part (22) is thus able to be moved between a constricted position and a released position allowing respectively the insertion and immobilization of a hollow part (100). Concretely, when the movable part (22) is in the tightened position, the hollow part (100) can be inserted at the same time on at least a portion of the static part (21) and on at least a portion of the movable part (22). But when the movable part (22) is in the released position, the hollow part (100) is in this case able to be blocked by the holding member (20), under the action of the pressure force exerted by the movable part (22) which is elastically stressed away from the part static (21) which then forms a stop.

    Selon une particularité de l'invention, la partie statique (21) de chaque organe de maintien (20) est solidarisée au cadre porteur (10) par une extrémité (23). Cette caractéristique présente l'avantage de rendre disponible la majeure partie de la partie statique (21) pour recevoir la pièce creuse. Ainsi donc, même lorsqu'elle est solidarisée au cadre porteur (10), la partie statique (21) est majoritairement accessible pour servir de support à toute pièce creuse (100) susceptible de venir s'insérer dessus.According to a feature of the invention, the static part (21) of each holding member (20) is secured to the support frame (10) by one end (23). This characteristic has the advantage of making available most of the static part (21) to receive the hollow part. So even when it is attached to the supporting frame (10), the static part (21) is mainly accessible to serve as support for any hollow part (100) capable of being inserted thereon.

    Selon une autre particularité de l'invention, la partie mobile (22) de chaque organe de maintien (20) comporte une extrémité libre (24) s'étendant en deçà du plan du cadre porteur (10), par rapport au corps proprement dit dudit organe de maintien (20). Cette caractéristique permet d'améliorer sensiblement l'accessibilité à la partie mobile (22), de sorte que la mise en oeuvre de l'organe de maintien (22) se voit avantageusement facilitée. L'extrémité libre (24) de la partie mobile (22) s'étend en effet dans une zone non encombrée, puisque située à l'opposé de la partie principale de l'organe de maintien (20) et de la pièce creuse (100) à traiter, par rapport au cadre porteur (10).According to another feature of the invention, the movable part (22) of each holding member (20) has a free end (24) extending below the plane of the supporting frame (10), relative to the body proper of said holding member (20). This characteristic significantly improves accessibility to the mobile part (22), so that the implementation of the holding member (22) is seen advantageously facilitated. The free end (24) of the movable part (22) indeed extends in an unencumbered area, since located opposite of the main part of the holding member (20) and of the hollow part (100) to be treated, with respect to the support frame (10).

    De manière particulièrement avantageuse, au moins une des parties statique (21) et mobile (22) de chaque organe de maintien (20) comporte un épaulement (25), formant butée, qui est apte à maintenir la pièce creuse (100) à distance du cadre porteur (10). Le but est avant tout de réaliser une sorte de mise en suspension de la pièce creuse (100) afin que le traitement de sa surface externe ne soit pas gêné par un éventuel contact entre le bord inférieur de ladite pièce creuse et la surface supérieure du cadre porteur (10). Dans cet exemple de réalisation, chaque organe de maintien (20) ne comporte qu'un seul épaulement (25) et il est ménagé sur la partie mobile (22).Particularly advantageously, at least one of the parts static (21) and mobile (22) of each holding member (20) comprises a shoulder (25), forming a stop, which is capable of holding the hollow part (100) at a distance from the support frame (10). The goal is above all to achieve a sort of suspension of the hollow part (100) so that the treatment of its external surface is not hampered by any contact between the edge lower of said hollow part and the upper surface of the support frame (10). In this exemplary embodiment, each holding member (20) does not has only one shoulder (25) and it is formed on the movable part (22).

    Selon un mode de réalisation actuellement préféré de l'invention, l'organe de maintien (20) est constitué par un élément flexible (30) ayant sensiblement la forme d'un U dont une branche (31), formant partie statique (21), est solidarisée au cadre porteur (10) par son extrémité libre (33) et dont l'autre branche (32), formant partie mobile (22), est montée élastiquement mobile en écartement par rapport à la branche statique (31). L'extrémité libre (34) de la branche mobile (32) s'étend en deçà du plan du cadre porteur (10), par rapport au corps proprement dit l'élément flexible en U (30).According to a currently preferred embodiment of the invention, the holding member (20) consists of a flexible element (30) having substantially the shape of a U including a branch (31), forming part static (21), is secured to the support frame (10) by its free end (33) and of which the other branch (32), forming a movable part (22), is mounted elastically movable in separation from the static branch (31). The free end (34) of the movable branch (32) extends below the plane of the supporting frame (10), relative to the body itself the flexible element U-shaped (30).

    Il va sans dire que les branches statique (31) et mobile (32) sont structurellement équivalentes puisqu' elles font parties intégrantes d'une seule et même pièce : l'élément flexible (30). Simplement, l'une d'entre elles (référence 31) est considérée comme statique car elle est fixée au cadre porteur (10) via son extrémité libre (33), tandis que l'autre (référence 32) est considérée comme mobile du fait que son extrémité libre (34) n'est pas liée. Comme, de plus, la structure de l'élément en U (30) est flexible, la branche mobile (32) peut ainsi avantageusement être déplacée en écartement par rapport à la branche statique (31), conférant ainsi son caractère déformable à l'organe de maintien (20).It goes without saying that the static (31) and mobile (32) branches are structurally equivalent since they are an integral part of a one and the same part: the flexible element (30). Simply, one of them (reference 31) is considered static because it is fixed to the frame carrier (10) via its free end (33), while the other (reference 32) is considered mobile because its free end (34) is not related. Since, moreover, the structure of the U-shaped element (30) is flexible, the movable leg (32) can thus advantageously be moved in spacing from the static branch (31), thereby imparting its deformable nature to the holding member (20).

    Ainsi qu'on peut le voir notamment sur la figure 1, les organes de maintien (20) sont ici régulièrement espacés sur le cadre porteur (10). Dans cet exemple de réalisation, les organes de maintien (20) se trouvent, en effet, parfaitement alignés et espacés, que ce soit dans le sens longitudinal ou dans le sens transversal. Pour cela, le cadre porteur (10) comporte plusieurs traverses transversales (11) le long desquelles sont solidarisées régulièrement un nombre constant d'organes de maintien (20). Le positionnement des différents organes de maintien (20) étant déterminé et connu, il est parfaitement envisageable d'automatiser à l'aide de robots le processus de mise en place des pièces creuses (100) sur le dispositif support (1). Cette caractéristique constitue un avantage décisif dans le cadre de l'industrialisation du procédé de traitement de surface envisagé.As can be seen in particular in Figure 1, the organs of here (20) are regularly spaced here on the support frame (10). In this embodiment, the holding members (20) are, in effect, perfectly aligned and spaced, whether in the longitudinal direction or in the transverse direction. For this, the supporting frame (10) comprises several transverse cross members (11) along which are secured regularly a constant number of holding organs (20). The positioning of the various holding members (20) being determined and known, it is perfectly possible to automate using robots the process of placing hollow parts (100) on the device support (1). This characteristic constitutes a decisive advantage in the industrialization of the envisaged surface treatment process.

    Selon une particularité de l'invention visible notamment sur les figures 3 et 4, le dispositif support (1) comporte, en outre, des moyens de libération (40) aptes à déplacer la partie mobile (22) de chaque organe de maintien (20) entre la position libérée et la position resserrée. Il est bien entendu que les positions libérée et resserrée constituent des limites et que, par conséquent, les moyens de libération (40) sont en mesure, d'une part, de déplacer toutes les parties mobiles (22) de manière continue et, d'autre part, d'immobiliser lesdites parties mobiles (22) dans n'importe quelle position intermédiaire. According to a feature of the invention visible in particular on Figures 3 and 4, the support device (1) further comprises means for release (40) capable of moving the movable part (22) of each member of holding (20) between the released position and the constricted position. It is well understood that the released and constricted positions constitute limits and that, consequently, the release means (40) are capable, of a part, to move all the moving parts (22) continuously and, on the other hand, to immobilize said movable parts (22) in any what an intermediate position.

    Conformément à la figure 2, les moyens de libération (40) sont constitués par un cadre libérateur (41) qui est destiné à être positionné parallèlement au cadre porteur (10), et qui comporte des moyens de butée (42) aptes à coopérer par contact avec la partie mobile (22) de chaque organe de maintien (20). Il est à noter que le cadre libérateur (41) et le cadre porteur (10) sont en fait montés mobiles en translation relative. Ainsi, les moyens de butée (42) sont aptes à entraíner le déplacement de parties mobiles (22), entre la position libérée et la position resserrée, au cours d'une translation relative entre le cadre libérateur (41) et le cadre porteur (10).According to Figure 2, the release means (40) are constituted by a release frame (41) which is intended to be positioned parallel to the support frame (10), and which includes stop means (42) able to cooperate by contact with the movable part (22) of each holding member (20). It should be noted that the liberating frame (41) and the support frame (10) are in fact mounted movable in relative translation. Thus, the stop means (42) are able to cause the movement of moving parts (22), between the released position and the constricted position, at during a relative translation between the liberating frame (41) and the frame carrier (10).

    Dans cet exemple de réalisation, les moyens de butée (42) sont constitués par plusieurs traverses (43) qui sont solidarisées au cadre libérateur (41) de manière sensiblement perpendiculaire à la direction de déplacement des parties mobiles (22) des organes de maintien (20). L'extrémité libre (24) de chaque partie mobile (22), qui est positionnée en deçà du plan du cadre porteur (10), s'étend ainsi dans la zone de déplacement d'une traverse (43) et peut, par conséquent, être actionnée lorsque le cadre libérateur (41) et le cadre porteur (10) sont animés d'un mouvement relatif de translation (figures 3 et 4).In this exemplary embodiment, the stop means (42) are constituted by several crosspieces (43) which are secured to the frame liberator (41) substantially perpendicular to the direction of displacement of the mobile parts (22) of the holding members (20). The free end (24) of each movable part (22), which is positioned in below the plane of the supporting frame (10), thus extends in the area of displacement of a crosspiece (43) and can therefore be actuated when the liberating frame (41) and the carrying frame (10) are animated by a relative translational movement (Figures 3 and 4).

    Conformément à une caractéristique avantageuse de l'invention, le dispositif support (1) peut également comporter des moyens moteurs aptes à générer une translation relative entre le cadre libérateur (41) et le cadre porteur (10). Cette particularité prend tout son sens dans le cadre de l'industrialisation du procédé de traitement de surface précédemment évoquée.In accordance with an advantageous characteristic of the invention, the support device (1) can also include motor means able to generate a relative translation between the liberating frame (41) and the supporting frame (10). This particularity takes on its full meaning in the context of the industrialization of the surface treatment process previously mentioned.

    De préférence, le cadre porteur est statique et le cadre libérateur est monté mobile en translation parallèlement audit cadre porteur. Preferably, the support frame is static and the release frame is mounted movable in translation parallel to said support frame.

    L'invention concerne également un procédé permettant de mettre en oeuvre un dispositif support 1 tel que précédemment décrit.The invention also relates to a method for putting using a support device 1 as previously described.

    La première étape de ce procédé consiste à mettre en place un cadre porteur (1) sur un cadre libérateur (41).The first step in this process is to set up a framework carrier (1) on a liberating frame (41).

    Au cours d'une seconde étape, les parties mobiles (22) de tous les organes de maintien (20) sont amenées en position resserrée, en réalisant une translation relative entre le cadre libérateur (41) et le cadre porteur (10).In a second step, the moving parts (22) of all the holding members (20) are brought into the constricted position, making a relative translation between the liberating frame (41) and the carrying frame (10).

    C'est durant une troisième étape que les pièces creuses (100) à traiter sont mises en place sur les organes de maintien (20) (figure 3).It is during a third stage that the hollow parts (100) to treat are placed on the holding members (20) (Figure 3).

    La quatrième étape consiste alors à amener les parties mobiles (22) de tous les organes de maintien (20) en position libérée, en réalisant à nouveau une translation relative entre le cadre libérateur (41) et le cadre porteur (10), mais cette fois dans le sens inverse de la seconde étape (figure 4).The fourth step then consists in bringing the moving parts (22) of all the holding members (20) in the released position, making again a relative translation between the liberating frame (41) and the frame carrier (10), but this time in the opposite direction to the second step (figure 4).

    Au cours de la cinquième étape, le cadre porteur (10) est avantageusement désolidarisé du cadre libérateur (41) afin de n'avoir que ledit cadre porteur (10) à manipuler.During the fifth step, the supporting frame (10) is advantageously separated from the liberating frame (41) so as to have only said support frame (10) to be manipulated.

    On procède ensuite, lors d'une sixième étape, au traitement effectif des pièces creuses (100) suivant un processus donné. Then, in a sixth step, the actual processing hollow parts (100) according to a given process.

    Le cadre porteur (10) est remis en place sur un cadre libérateur (41) durant une septième étape. Il est à noter que ce cadre libérateur (41) peut être, ou non, le même que celui des cinq premières étapes.The supporting frame (10) is replaced on a releasing frame (41) during a seventh stage. It should be noted that this liberating framework (41) can or not be the same as in the first five steps.

    La dernière étape consiste alors à libérer les pièces creuses (100), en amenant à nouveau les parties mobiles (22) de tous les organes de maintien (20) en position resserrée. Cette opération peut être avantageusement réalisée en retournant l'ensemble des deux cadres (10, 41), de manière à ce que les pièces creuses (100) traitées puissent se désengager des organes de maintien (20) par simple gravité, avant de tomber tout aussi avantageusement dans un collecteur de récupération.The last step is then to release the hollow parts (100), again bringing the movable parts (22) of all the organs of holding (20) in the closed position. This operation can be advantageously carried out by turning over the whole of the two frames (10, 41), so that the hollow parts (100) treated can be disengage holding members (20) by simple gravity, before just as advantageously fall into a recovery collector.

    On a compris que le cadre porteur (10) du dispositif support (1) comporte au moins une traverse transversale (11) le long de laquelle est solidarisé au moins un organe de maintien (20), ainsi que les moyens de butée (42) du dispositif support (1) sont constitués par au moins une traverse (43) qui est solidarisée au cadre libérateur (41) de manière sensiblement perpendiculaire à la direction de déplacement de la partie mobile (22) de chaque organe de maintien (20), l'extrémité libre (24) de chaque partie mobile (22), qui est positionnée en deçà du plan du cadre porteur (10), s'étendant dans la zone de déplacement d'une traverse (43).It has been understood that the support frame (10) of the support device (1) comprises at least one transverse cross member (11) along which is secured at least one holding member (20), as well as the means of stop (42) of the support device (1) consist of at least one crosspiece (43) which is secured to the release frame (41) so substantially perpendicular to the direction of movement of the part mobile (22) of each holding member (20), the free end (24) of each movable part (22), which is positioned below the plane of the frame carrier (10), extending in the displacement region of a cross member (43).

    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 modes of realization described and represented as examples, but it includes also all technical equivalents and their combinations.
