Description

DISPOSITIF POUR DEPLACER VERTICALEMENT UN OU PLUSIEURS OBJETS TOUT EN CONSERVANT LEUR ORIENTATION ET LEUR POSITIONNEMENT DEFINIS INITIALEMENT.DEVICE FOR VERTICALLY MOVING ONE OR MORE OBJECTS WHILE MAINTAINING THEIR ORIENTATION AND POSITIONING DEFINED INITIALLY.
La présente invention a pour objet un dispositif pour déplacer verticalement un ou plusieurs objets tout en conservant leur orientation et leur positionnement définis initialement.The subject of the present invention is a device for vertically moving one or more objects while retaining their orientation and their positioning defined initially.
Un tel dispositif trouvera, non limitativement, une application particulière dans le domaine de l'agencement de magasin, notamment pour suspendre aussi bien des affiches que des objets publicitaires ou des articles proposés à la vente.Such a device will find, without limitation, a particular application in the field of store layout, in particular for hanging posters as well as advertising objects or articles offered for sale.
De manière générale, la suspension de tels objets ou articles est réalisée au travers d'éléments filaires , ou brins, accrochés au plafond du local à équiper. Les plus aboutis des dispositifs comprenant ces éléments filaires sont associés à des moyens d'enroulement de type treuil qui facilitent la manutention de ces objets ou articles, c'est-à-dire les opérations d'accrochage et de décrochage , en permettant de les amener à hauteur d' homme .In general, the suspension of such objects or articles is carried out through wire elements, or strands, hung on the ceiling of the room to be equipped. The most successful of the devices comprising these wire elements are associated with winch-type winding means which facilitate the handling of these objects or articles, that is to say the hooking and unhooking operations, by enabling them to be bring it up to human height.
Lorsque ces dispositifs ne comportent qu'un seul brin, il est facile de régler la hauteur des objets ou articles accrochés, mais il est toutefois préféré d' accrocher de tels objets ou articles au moyen de plusieurs brins pour éviter que ces derniers se mettent à tourner, et/ou pour leur donner une orientation particulière .When these devices comprise only one strand, it is easy to adjust the height of the objects or articles hung, but it is however preferred to hang such objects or articles by means of several strands to prevent them from starting to rotate, and / or to give them a particular orientation.
Lorsque ces dispositifs comportent plusieurs brins, notamment deux, ceux-ci ont des courses identiques et, sauf à disposer d'un objet ou article présentant des points d'accrochage parfaitement alignés horizontalement, ou à calculer de combien raccourcir certains desdits brins et à réaliser ledit raccourcissement, il est difficile de déplacer verticalement lesdits objets ou articles tout en leur conservant leur orientation et leur positionnement définis initialement. Pour pallier cet inconvénient on utilise généralement plusieurs dispositifs à un seul brin de suspension pilotés individuellement, éventuellement simultanément au moyen d'un automate .When these devices comprise several strands, in particular two, these have identical strokes and, except for having an object or article having hooking points perfectly aligned horizontally, or calculating how much to shorten some of said strands and to carry out said shortening, it is difficult to vertically move said objects or articles while retaining their orientation and positioning initially defined. To overcome this drawback, several devices with a single strand of suspension are generally used, controlled individually, possibly simultaneously by means of an automaton.
De telles installations sont toutefois relativement onéreuses, et difficilement implantables en tous lieux .Such installations are however relatively expensive, and difficult to install everywhere.
La présente invention a pour but de remédier à ces divers inconvénients en proposant un dispositif pour déplacer verticalement un ou plusieurs objets tout en conservant leur orientation et leur positionnement définis initialement, de conception simple et peu onéreuse .The present invention aims to remedy these various drawbacks by proposing a device for vertically moving one or more objects while retaining their orientation and their initially defined positioning, of simple and inexpensive design.
Le dispositif pour déplacer verticalement un ou plusieurs objets tout en conservant leur orientation et leur positionnement définis initialement selon l'invention, comprend un arbre apte à être mû en rotation par un moyen moteur pour enrouler ou dérouler au moins deux brins servant à la suspension du ou desdits objets, et il se caractérise en ce que ledit arbre porte plusieurs modules d'enroulement, un pour chacun desdits brins, chacun desdits modules comprenant un élément destiné à recevoir le brin enroulé, et lié audit arbre au travers de moyens aptes à être débrayés .The device for vertically moving one or more objects while retaining their orientation and their positioning defined initially according to the invention, comprises a shaft capable of being rotated by a motor means for winding or unwinding at least two strands used for the suspension of the or of said objects, and it is characterized in that said shaft carries several winding modules, one for each of said strands, each of said modules comprising an element intended to receive the wound strand, and linked to said tree through means capable of being disengaged.
Un tel dispositif permet de dérouler, en position débrayée, la longueur de brin nécessaire, puis de figer cette longueur pour chacun des brins, et de conserver les différences de longueur au gré des opérations d'enroulement et de déroulement.Such a device makes it possible to unwind, in the disengaged position, the required length of strand, then to freeze this length for each of the strands, and to keep the differences in length according to the winding and unwinding operations.
Selon une caractéristique additionnelle du dispositif selon l'invention, les moyens de débrayage sont définis par des moyens de friction aptes à assurer la liaison entre l'élément destiné à recevoir le brin enroulé et l'arbre, en deçà d'un couple d'une certaine valeur . Selon un mode de réalisation particulier du dispositif selon l'invention chaque module d'enroulement comprend un premier élément tubulaire enfilé sur l'arbre et solidaire en rotation de celui-ci, et coopérant avec un second élément tubulaire en libre rotation sur ledit arbre et servant de bobine d'enroulement au brin, les parties coopérantes desdits éléments tubulaires étant aptes à coopérer par friction sous l'action d'un moyen élastique poussant l'un desdits éléments tubulaires en direction de l'autre.According to an additional characteristic of the device according to the invention, the declutching means are defined by friction means capable of ensuring the connection between the element intended to receive the wound strand and the shaft, below a torque of some value. According to a particular embodiment of the device according to the invention, each winding module comprises a first tubular element threaded on the shaft and integral in rotation with the latter, and cooperating with a second tubular element in free rotation on said shaft and serving as a strand winding reel, the cooperating parts of said tubular elements being able to cooperate by friction under the action of an elastic means pushing one of said tubular elements towards the other.
Selon une caractéristique additionnelle du mode de réalisation particulier du dispositif selon l'invention, le moyen élastique consiste en un ressort dont la pression est réglable.According to an additional characteristic of the particular embodiment of the device according to the invention, the elastic means consists of a spring whose pressure is adjustable.
On notera que de manière avantageuse la valeur du couple seuil peut être choisie en sorte que le dispositif fonctionne comme un limiteur de couple .It will be noted that advantageously the value of the threshold torque can be chosen so that the device functions as a torque limiter.
Selon une autre caractéristique additionnelle du dispositif selon l'invention, chacun des brins est associé à un moyen de butée de longueur prédéterminée, contre lequel l'objet vient en butée lors de l'enroulement.According to another additional characteristic of the device according to the invention, each of the strands is associated with an abutment means of predetermined length, against which the object comes into abutment during winding.
Les avantages et les caractéristiques du dispositif selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the device according to the invention will emerge more clearly from the description which follows and which relates to the appended drawing, which represents a non-limiting embodiment thereof.
Dans le dessin annexé la figure unique représente une schématique et en perspective d'un dispositif selon l'invention.In the accompanying drawing, the single figure represents a schematic and perspective view of a device according to the invention.
En référence à cette figure, on peut voir un dispositif pour déplacer verticalement un ou plusieurs objets tout en conservant leur orientation et leur positionnement définis initialement selon l'invention comprend un carter 1 renfermant un arbre 2 apte à être mû en rotation par un moteur 3.With reference to this figure, one can see a device for vertically moving one or more objects while retaining their orientation and their positioning defined initially. according to the invention comprises a casing 1 containing a shaft 2 capable of being rotated by a motor 3.
Le dispositif comprend plusieurs modules 4 d'enroulement de brins 40, 41 et 42.The device comprises several modules 4 for winding strands 40, 41 and 42.
Chaque module d'enroulement est défini par un élément tubulaire 43 enfilé sur l'arbre 2 et solidarisé en rotation à celui-ci, et un élément tubulaire 44 également enfilé sur l'arbre 2 mais en libre rotation, et destiné à l'enroulement des brins 40, 41 et 42.Each winding module is defined by a tubular element 43 threaded on the shaft 2 and secured in rotation to the latter, and a tubular element 44 also threaded on the shaft 2 but in free rotation, and intended for winding strands 40, 41 and 42.
Les éléments tubulaires 43 et 44 coopèrent l'un avec l'autre par l'intermédiaire d'une zone de friction et sous l'action d'un ressort 45 qui repousse l'élément tubulaire 44 vers l'élément tubulaire 43.The tubular elements 43 and 44 cooperate with each other by means of a friction zone and under the action of a spring 45 which pushes the tubular element 44 towards the tubular element 43.
La pression exercée par le ressort 45 est réglable, au moyen d'un système vis écrou ou analogue.The pressure exerted by the spring 45 is adjustable, by means of a screw nut system or the like.
La rotation de l'arbre 2 sous l'action du moteur 1 permet donc simultanément l'enroulement et le déroulement des brins 40, 41 et 42, par contre les modules 4 permettent de régler individuellement la longueur des brins 41, 41 et 42 en y exerçant une traction de force suffisante à vaincre la résistance du moyen de fiction concerné.The rotation of the shaft 2 under the action of the motor 1 therefore simultaneously allows the winding and unwinding of the strands 40, 41 and 42, on the other hand the modules 4 allow the length of the strands 41, 41 and 42 to be adjusted individually. exerting a pull of sufficient force to overcome the resistance of the means of fiction concerned.
Dans l'exemple représenté, le dispositif selon l'invention permet de suspendre deux objets, un objet 5 suspendu au brin 40, et un objet 6 suspendu aux brins 41 et 41. Les objets 5 et 6 ne sont pas à suspendre à la même hauteur, par contre il est nécessaire pour les opérations d' accrochage et de décrochage de les amener à hauteur d'homme. Le dispositif selon l'invention permet d'obtenir ce résultat avec un seul appareil , puisque la longueur de chacun des brins 40, 41 et 42 est réglable individuellement.In the example shown, the device according to the invention makes it possible to suspend two objects, an object 5 suspended from the strand 40, and an object 6 suspended from the strands 41 and 41. The objects 5 and 6 are not to be hung from the same height, on the other hand it is necessary for the operations of hooking and unhooking to bring them to the height of a man. The device according to the invention makes it possible to obtain this result with a single device, since the length of each of the strands 40, 41 and 42 is individually adjustable.
Le réglage de la longueur peut également être obtenu de manière plus précise et automatique, par l'intermédiaire d'éléments de butée 10, solidaire du carter 1, et contre lesquels vient buter l'objet 6 lors de l'enroulement des brins 41 et 42.The length adjustment can also be obtained more precisely and automatically, by means of stop elements 10, integral with the casing 1, and against which the object 6 abuts when the strands 41 are wound up and 42.
Les éléments de butée 10 sont de longueurs prédéterminées en fonction de l'objet à suspendre. En pratique, les brins sont déroulés, puis le ou les objets y sont accrochés, les brins sont ensuite enroulés jusqu' à ce que le ou les objets viennent en butée contre les éléments 10 pour régler les longueurs des brins les uns par rapport aux autres ce qui est permis du fait du débrayage , ils peuvent ensuite être déroulés pour amener les objets à la hauteur désirée tout en conservant leur orientation initiale, ainsi que les positions des objets les uns par rapport aux autres .The stop elements 10 are of predetermined lengths depending on the object to be hung. In practice, the strands are unrolled, then the object or objects are hung there, the strands are then wound until the object or objects come into abutment against the elements 10 to adjust the lengths of the strands relative to each other which is allowed due to the declutching, they can then be unrolled to bring the objects to the desired height while retaining their initial orientation, as well as the positions of the objects relative to each other.
On notera que dans le cas d' un alignement horizontal des points de fixation du ou des objets, c'est le carter 1 qui peut faire office de butée . It will be noted that in the case of a horizontal alignment of the fixing points of the object or objects, it is the casing 1 which can act as a stop.
