Abstract
Description
La présente invention concerne un dispositif de fixation, notamment pour un organe support de longerons de rayonnages à clayettes sur un support muni d'ouvertures régulièrement espacées, comme utilisé généralement pour les produits alimentaires. The present invention relates to a fixing device, in particular for a support member for beams of shelving shelves on a support provided with regularly spaced openings, as generally used for food products.
On connait de tels rayonnages décrits par exemple dans le brevet français 82 06 056, composés d'échelles reliées par des longerons munis de profilés pour supporter des clayettes. Ces longerons sont reliés aux montants des échelles par l'intermédiaire d'organes d'accrochage comportant une échancrure en forme de V pour recevoir un axe du longeron. Cet organe d'accrochage comporte à sa face arrière, c'est-à-dire celle en contact avec une face avant du montant, un filetage prévu pour coopérer avec un vis traversant le montant et venant en appui sur une face arrière du montant. We know of such shelving described for example in French patent 82 06 056, composed of ladders connected by side members provided with profiles to support shelves. These beams are connected to the uprights of the ladders by means of hooking members comprising a V-shaped notch to receive an axis of the beam. This attachment member comprises at its rear face, that is to say that in contact with a front face of the upright, a thread provided for cooperating with a screw passing through the upright and coming to bear on a rear face of the upright.
Il est courant d'installer de tels rayonnages dans le prolongement les uns des autres, dans un angle de mur, ou même perpendiculairement à un mur et appuyé contre celui-ci. It is common to install such shelving in the extension of each other, in a corner of the wall, or even perpendicular to a wall and pressed against it.
Dans de tels cas on ne peut accéder aux vis de fixation de l'organe d'accrochage sans déplacer l'ensemble du rayonnage, ce qui est un inconvénient majeur pour modifier la disposition des clayettes. De plus, un seul montant ne peut être utilisé pour deux organes d'accrochage situés à la même hauteur, de part et d'autre du montant. Une seule échelle ne peut donc etre utilisée pour deux rayonnages situés dans le prolongement l'un de l'autre. In such cases, the fixing screws of the hooking member cannot be accessed without displacing the whole of the shelving, which is a major drawback for modifying the arrangement of the shelves. In addition, a single upright cannot be used for two hooking members located at the same height, on either side of the upright. A single ladder cannot therefore be used for two shelves located in the extension of one another.
Pour remédier à ces inconvénients, 1 'inven- tion a pour but de fixer un organe sur un support muni d'une ouverture de façon telle que l'organe soit aisément amovible sans nécessiter le déplacement de l'en semble du rayonnage et qu'il permette .en outre d'utiliser un même support pour supporter à la même hauteur deux longerons dans le prolongement l'un de l'autre. To remedy these drawbacks, the object of the invention is to fix a member on a support provided with an opening so that the member is easily removable without requiring the displacement of the whole of the shelving and that it allows. in addition to use the same support to support at the same height two beams in the extension of one another.
A cet effet, l'invention a pour but un dispositif de fixation d'une pièce sur un support comportant une paroi délimitant une ouverture, une face avant et une face arrière, la pièce à fixer comportant elle-même une face avant et une face arrière en appui contre la face avant du support, le dispositif de fixation comprenant de plus un premier et un second organes filetés complémentaires, prenant respectivement appui sur la face arrière du support et sur la face avant de la pièce a fixer, au moins un des deux organes filetés s'étendant dans un logement qui est ménagé dans la pièce à fixer et qui débouche dans ses faces avant et arrière, caractérisé en ce qu'il est prévu des moyens pour bloquer en rotation le premier organe fileté et l'empêcher de tourner lorsque l'autre organe est actionné pour serrer ou desserrer le dispositif. To this end, the object of the invention is a device for fixing a part on a support comprising a wall defining an opening, a front face and a rear face, the part to be fixed itself comprising a front face and a face rear bearing against the front face of the support, the fixing device further comprising a first and a second complementary threaded members, taking support respectively on the rear face of the support and on the front face of the part to be fixed, at least one of the two threaded members extending in a housing which is formed in the part to be fixed and which opens into its front and rear faces, characterized in that means are provided for locking in rotation the first threaded member and preventing it from turn when the other member is actuated to tighten or loosen the device.
Selon d'autres caractéristiques
- le premier organe fileté comporte une gorge délimitée par deux faces latérales et un fond, lesdites faces latérales s'étendant sensiblement perpendiculairement à l'axe des parties filetées des organes filetés, l'une de ces faces servant de surface d'appui contre la face arrière de la paroi du support;
- le premier organe fileté a une forme générale cylindrique, de section circulaire, et il est re çu dans une portion de forme correspondante du logement ménagé dans la pièce à fixer;
- les organes filetés complémentaires comportent chacun une partie filetée, respectivement mâle et femelle, l'axe de ces parties filetées étant décalé par rapport à l'axe de la surface cylindrique exté rieure du premier organe fileté;;
- le fond de ladite gorge est constitué par une surface cylindrique, convexe, de section circulaire, coaxiale auxdites parties filetées;
- le logement ménagé dans la pièce à fixer comporte une première partie recevant le premier organe fileté et une deuxième partie de section plus faible que la première, la longueur de la première partie étant telle qu'un jeu axial subsiste entre le fond de cette première partie et le premier organe fileté, en position de serrage du dispositif.According to other characteristics
- The first threaded member has a groove delimited by two lateral faces and a bottom, said lateral faces extending substantially perpendicular to the axis of the threaded parts of the threaded members, one of these faces serving as a bearing surface against the rear face of the support wall;
- The first threaded member has a generally cylindrical shape, of circular section, and it is received in a correspondingly shaped portion of the housing formed in the part to be fixed;
- The complementary threaded members each comprise a threaded part, male and female respectively, the axis of these threaded parts being offset with respect to the axis of the external cylindrical surface of the first threaded member;
- The bottom of said groove is constituted by a cylindrical, convex surface, of circular section, coaxial with said threaded parts;
the housing formed in the part to be fixed comprises a first part receiving the first threaded member and a second part of smaller section than the first, the length of the first part being such that an axial clearance remains between the bottom of this first part and the first threaded member, in the device clamping position.
L'invention va être décrite plus en détail ci-après en se référant aux dessins annexés, donnés uniquement à titre d'exemple et sur lesquels
- la Figure 1 est une vue en perspective éclatée de l'ensemble du dispositif selon l'invention;
- la Figure 2 est une vue en coupe du dispositif de fixation selon l'invention.The invention will be described in more detail below with reference to the accompanying drawings, given only by way of example and in which
- Figure 1 is an exploded perspective view of the assembly of the device according to the invention;
- Figure 2 is a sectional view of the fixing device according to the invention.
Sur la Figure 1, le support référencé 1 est du type tubulaire à section carrée comportant une paroi avant 2 pourvue d'une face arrière 3 et d'une face avant 4 , et une paroi arrière 5. Cette face avant 4 est délimitée par deux rebords situés symétriquement par rapport à l'axe longitudinal de la face. Ces rebords définissent un canal de faible profondeur et d'une largeur légèrement supérieure à celle de la pièce à fixer. Au travers de la paroi avant 2 est prévue une ouverture circulaire 6. Un premier organe 7 fileté appartenant au dispositif de fixation selon l'invention est cylindrique de section circulaire légèrement inférieure à celle de l'ouverture 6. La face avant de celui-ci est munie d'un trou fileté 8 excentré par rapport à l'axe du premier organe 7 d'une distance a. In FIG. 1, the support referenced 1 is of the tubular type with square section comprising a front wall 2 provided with a rear face 3 and with a front face 4, and a rear wall 5. This front face 4 is delimited by two edges located symmetrically with respect to the longitudinal axis of the face. These edges define a shallow channel and a width slightly greater than that of the part to be fixed. Through the front wall 2 is provided a circular opening 6. A first threaded member 7 belonging to the fixing device according to the invention is cylindrical with a circular section slightly smaller than that of the opening 6. The front face thereof is provided with a threaded hole 8 eccentric with respect to the axis of the first member 7 by a distance a.
A proximité de sa face arrière, le premier organe 7 comporte une gorge dont l'une des faces latérales 9 s'étend sensiblement perpendiculairement à l'axe de la partie filetée. L'autre face latérale de la gorge détermine la largeur de celle-ci, largeur supérieure à l'épaisseur de la paroi avant 2 du support 1. Le fond 10 de la gorge est constitué par une surface cylindrique, convexe, de section circulaire, coaxiale avec le trou fileté 8 du premier organe 7. La pièce 11 à fixer sur le support 1 comporte une échancrure 12 en forme de V ouvert vers le haut. La pièce à fixer comporte une face arrière 13 et une face avant 14. A la face arrière débouche un logement 15 cylindrique de diamètre correspondant à celui du premier organe 7.Ce logement 15 débouche â la face avant 14 de la pièce à fixer par un orifice 16 de diamètre correspondant à l'alésage fileté 8 du premier organe fileté 7. L'axe de cet orifice 16 est décalé par rapport à l'axe du logement 15 d'une distance a vers le haut. Cette distance a est la même que la distance a existant entre l'axe de la partie filetée du premier organe 7 et l'axe de ce dernier. Cet alésage 16 débouche à la surface 14 par une partie tronconique 17 destinée à recevoir la tête d'une vis 18.Near its rear face, the first member 7 has a groove, one of the side faces 9 of which extends substantially perpendicular to the axis of the threaded part. The other lateral face of the groove determines the width thereof, width greater than the thickness of the front wall 2 of the support 1. The bottom 10 of the groove is constituted by a cylindrical, convex surface, of circular section, coaxial with the threaded hole 8 of the first member 7. The part 11 to be fixed on the support 1 has a V-shaped notch 12 open upwards. The part to be fixed has a rear face 13 and a front face 14. At the rear face opens a cylindrical housing 15 of diameter corresponding to that of the first member 7. This housing 15 opens at the front face 14 of the part to be fixed by a orifice 16 of diameter corresponding to the threaded bore 8 of the first threaded member 7. The axis of this orifice 16 is offset with respect to the axis of the housing 15 by a distance a upwards. This distance a is the same as the distance a existing between the axis of the threaded part of the first member 7 and the axis of the latter. This bore 16 opens at the surface 14 by a frustoconical part 17 intended to receive the head of a screw 18.
Dans une première étape, on introduit le premier organe 7 dans le logement 15 de la pièce à fixer de manière à ce que l'alésage fileté 8 vienne dans le prolongement de l'alésage 16 de la pièce à fixer. La vis 18 est engagée au travers de l'alésage 16 et se trouve en prise par quelques filets avec le trou fileté 8. Le premier organe 7 est ainsi orienté dans son logement de façon telle que la gorge située à proximité de son extrémité arrière est orientée vers le bas. De plus, lorsque il est nécessaire de visser la vis 18 dans l'alésage fileté 8, le premier organe 7 ne pourra tourner dans son logement, ce qui facilite la mise en place de l'ensemble du dispositif de fixation. Le fait que la vis 18 ne soit en prise que sur quelques filets permet de faire ressortir l'extrémité arrière du premier organe 7 hors du logement 15.Ainsi, dans un deuxième temps, est-il possible de faire traverser l'ouverture 6 de la paroi 2 du support 1 par l'extrémité arrière du premier organe 7. A ce moment, la face arrière 13 de la pièce à fixer 11 vient pratiquement en appui sur la face avant 4 de la paroi avant 2 du support 1. Un léger mouvement vers le bas permet au fond 10 de la gorge de venir en contact avec la partie basse de l'ouverture 6. A ce moment, la face latérale plane 9 de la gorge du premier organe 7 vient pratiquement en appui sur la face arrière 3 de la paroi avant 2 du support 1. L'ensemble à fixer est alors accroché au support 1. In a first step, the first member 7 is introduced into the housing 15 of the part to be fixed so that the threaded bore 8 comes in the extension of the bore 16 of the part to be fixed. The screw 18 is engaged through the bore 16 and is engaged by a few threads with the threaded hole 8. The first member 7 is thus oriented in its housing so that the groove located near its rear end is facing down. In addition, when it is necessary to screw the screw 18 into the threaded bore 8, the first member 7 can not rotate in its housing, which facilitates the establishment of the entire fixing device. The fact that the screw 18 is engaged only on a few threads makes it possible to bring out the rear end of the first member 7 out of the housing 15. Thus, in a second step, is it possible to pass through the opening 6 of the wall 2 of the support 1 by the rear end of the first member 7. At this time, the rear face 13 of the part to be fixed 11 comes practically to bear on the front face 4 of the front wall 2 of the support 1. A slight downward movement allows the bottom 10 of the groove to come into contact with the lower part of the opening 6. At this time, the flat lateral face 9 of the groove of the first member 7 comes to bear practically on the rear face 3 of the front wall 2 of the support 1. The assembly to be fixed is then hooked to the support 1.
Dans un troisième temps, la vis 18 est serrée à l'aide d'une clé adéquate ou d'un tournevis, ce qui permet d'assurer un serrage entre la paroi latérale 9 de la gorge du premier organe 7, la face arrière 3 de la paroi avant 2 du support, la tête de vis 18 et la partie tronconique 17 prévue dans la face avant 14 de la pièce à fixer. Thirdly, the screw 18 is tightened using an adequate key or a screwdriver, which makes it possible to ensure a tightening between the side wall 9 of the groove of the first member 7, the rear face 3 of the front wall 2 of the support, the screw head 18 and the frustoconical part 17 provided in the front face 14 of the part to be fixed.
La distance entre la face latérale 9 de la gorge et l'extrémité du premier organe 7 opposée à son trou fileté est inférieure à une demi-largeur du support 1. On peut ainsi aisément envisager de placer deux pièces à fixer 11 à une même hauteur et sur deux faces opposées du support 1 comportant chacune une ouverture 6. The distance between the lateral face 9 of the groove and the end of the first member 7 opposite its threaded hole is less than half the width of the support 1. It is thus easy to envisage placing two pieces to be fixed 11 at the same height and on two opposite faces of the support 1 each comprising an opening 6.
Par ailleurs, il est évident que l'accès à la vis de serrage 18 se faisant par la face avant de la pièce à fixer 11, il est très facile de retirer le dispositif de fixation et de le reporter au travers d'une autre ouverture du même support ou d'une autre paroi de support. Furthermore, it is obvious that access to the clamping screw 18 is via the front face of the part to be fixed 11, it is very easy to remove the fixing device and to transfer it through another opening of the same support or another support wall.
Selon une variante, le premier organe 7 est muni d'une nervure longitudinale et la première partie du logement 15 comporte une rainure corespondante. Alternatively, the first member 7 is provided with a longitudinal rib and the first part of the housing 15 has a corresponding groove.
Dans ce cas, il n'est pas nécessaire de décaler l'axe du trou fileté 8 du premier organe 7 pour obtenir un blocage en rotation et une orientation correcte du premier organe.In this case, it is not necessary to offset the axis of the threaded hole 8 of the first member 7 in order to obtain a rotation lock and a correct orientation of the first member.
L'homme de l'art peut aisément envisager d'autres moyens qui amènent au même résultat. Par exemple, on peut imaginer que l'ouverture 6 du support 1 présente à sa partie inférieure une face plane et que la gorge prévue à l'extrémité arrière du premier organe 7 comporte un fond plat. L'axe du trou fileté 8 peut alors, par exemple, être confondu avec l'axe du premier organe 7. Those skilled in the art can easily envisage other means which lead to the same result. For example, one can imagine that the opening 6 of the support 1 has at its lower part a flat face and that the groove provided at the rear end of the first member 7 has a flat bottom. The axis of the threaded hole 8 can then, for example, coincide with the axis of the first member 7.
Compte-tenu de sa facilité de réalisation en une seule passe d'usinage, le premier organe décrit ci-dessus ayant un trou fileté décalé et un fond de gorge cylindrique coaxial à ce dernier fait partie du mode de réalisation préféré de l'invention. Given its ease of production in a single machining pass, the first member described above having an offset threaded hole and a cylindrical groove bottom coaxial with the latter is part of the preferred embodiment of the invention.
