Abstract

The scaffolding stage (1) mounting on an upright (2) has two sleeves (3,4) which inter-fit. The inner sleeve (3) is rotationally connected to the upright so that when the outer sleeve (4) is moved in translation on the stage, the rotation of the outer sleeve causes locking onto the upright.

Description

La présente invention est relative à un dispositif permettant de fixer une étagère sur un montant vertical. The present invention relates to a device for fixing a shelf on a vertical upright.

Le premier problème à résoudre consiste à fixer l'étagère sans I'aide d'outil. The first problem to solve is to fix the shelf without using a tool.

Le second problème à résoudre consiste à réaliser un dispositif permettant de déplacer l'étagère de façon continue puis à la bloquer à la hauteur requise. Compte tenu de cette exigence, il n'est pas possible d'utiliser un dispositif du genre de ceux dit à crémaillère. The second problem to be solved consists in making a device making it possible to move the shelf continuously and then to block it at the required height. In view of this requirement, it is not possible to use a device of the type of the so-called rack.

La présente invention est remarquable en ce que le dispositif fait appel à deux manchons, engagés l'un dans I'autre, dont l'un est lié en rotation au montant tandis que I'autre est lié en translation à l'étagère, la rotation dudit second manchon provoquant le serrage du premier sur ledit montant. The present invention is remarkable in that the device uses two sleeves, engaged one in the other, one of which is linked in rotation to the upright while the other is linked in translation to the shelf, the rotation of said second sleeve causing the tightening of the first on said upright.

Selon un mode de réalisation, le second manchon fait partie intégrante de l'étagère. De cette façon, par une rotation de cette dernière, il est possible de réaliser un serrage énergique. According to one embodiment, the second sleeve is an integral part of the shelf. In this way, by a rotation of the latter, it is possible to achieve an energetic tightening.

La présente invention sera mieux comprise par la description qui va suivre faite en se référant aux dessins annexés à titre d'exemple indicatif, seulement, sur lesquels :
-la figure 1 est une vue en coupe effectuée selon la ligne l-l de la figure 2 ;
-la figure 2 est une vue en coupe effectuée selon la ligne 11-11 de la figure ;
-la figure 3 est une vue analogue à cette 1, le dispositif étant représenté en position de blocage de t'étagère ;
-la figure 4 est une vue partielle et à plus grande échelle montrant, en coupe horizontale, un détail de réalisation du montant.
The present invention will be better understood from the following description made with reference to the accompanying drawings by way of indicative example only, in which:
FIG 1 is a sectional view taken along line II of Figure 2;
FIG 2 is a sectional view taken along line 11-11 of the figure;
FIG. 3 is a view similar to this 1, the device being shown in the locking position of the shelf;
FIG 4 is a partial view on a larger scale showing, in horizontal section, a detail of the amount of the upright.

En se reportant aux dessins, on voit que le problème à résoudre consiste à fixer une étagère 1 en un point quelconque de la hauteur d'un montant 2 vertical. Referring to the drawings, it can be seen that the problem to be solved consists in fixing a shelf 1 at any point of the height of a vertical upright 2.

Ce résultat est obtenu en utilisant deux manchons 3 et 4, engagés axialement l'un dans l'autre, celui 4 étant ajusté sur le montant 2 mais pouvant coulisser librement sur ce dernier. This result is obtained by using two sleeves 3 and 4, axially engaged one inside the other, that 4 being adjusted on the upright 2 but being able to slide freely on the latter.

Si la section du montant 2 est circulaire, un moyen est prévu pour immobiliser le manchon 4 en rotation, une clavette 5, par exemple, guidée dans une rainure longitudinale 6 dudit montant. Cette clavette peut faire partie intégrante du manchon 4. If the section of the upright 2 is circular, a means is provided for immobilizing the sleeve 4 in rotation, a key 5, for example, guided in a longitudinal groove 6 of said upright. This key can be an integral part of the sleeve 4.

Le manchon 4 présente des fentes 7, sensiblement radiales, ne s'étendant pas sur toute sa hauteur. The sleeve 4 has slots 7, substantially radial, not extending over its entire height.

Les manchons 3 et 4 présentent des moyens agencés de façon à ce que la rotation du manchon 3 provoque des forces radiales qui déterminent la déformation élastique dudit manchon 4 et appliquent ses parties comprises entre les fentes contre le montant 2. The sleeves 3 and 4 have means arranged so that the rotation of the sleeve 3 causes radial forces which determine the elastic deformation of said sleeve 4 and apply its parts comprised between the slots against the upright 2.

Selon un mode de réalisation, la face externe du manchon 4 présente des bossages 8, tandis que celle interne du manchon 3 présente des bossages 9. Les sommets 9a des bossages 9 sont situés sur une circonférence dont le diamètre est inférieure à celle sur laquelle sont situés les sommets 8a des bossages 8. According to one embodiment, the external face of the sleeve 4 has bosses 8, while that internal of the sleeve 3 has bosses 9. The vertices 9a of the bosses 9 are located on a circumference whose diameter is less than that on which are located the vertices 8a of the bosses 8.

De cette façon, si on fait pivoter le manchon 3 selon la flèche F1, les bossages 9 s'appliquent contre ceux 8 (voir fig. 3) et provoquent la déformation élastique des portions du manchon comprises entre les fentes 7. On réalise ainsi le blocage de l'ensemble sur le montant 2. In this way, if the sleeve 3 is pivoted according to the arrow F1, the bosses 9 are applied against those 8 (see fig. 3) and cause the elastic deformation of the portions of the sleeve included between the slots 7. This produces the blocking of the assembly on the upright 2.

Le manchon 3 est lié en rotation et en translation à t'étagère 1, i I peut mme en faire partie intégrante. The sleeve 3 is linked in rotation and in translation to the shelf 1, i I may even be an integral part thereof.

Des moyens, non représentés, peuvent tre utilisés pour que I e déplacement vertical de t'étagère détermine celui du manchon central 4. Means, not shown, can be used so that the vertical displacement of the shelf determines that of the central sleeve 4.

Ainsi, par exemple, le manchon 4 peut présenter un épaulement interne contre lequel prend appui la partie inférieure du manchon central : en soulevant t'étagère, on entraîne le manchon 3.Thus, for example, the sleeve 4 may have an internal shoulder against which the lower part of the central sleeve bears: by lifting the shelf, the sleeve 3 is driven.

Selon un autre mode de réalisation, le serrage est obtenu en utilisant un dispositif à vis et écrou coniques, le manchon 4 constituant la vis et celui 3 t'écrou.  According to another embodiment, the tightening is obtained by using a device with conical screw and nut, the sleeve 4 constituting the screw and that 3 the nut.

Selon une autre caractéristique de l'invention et comme cela ressort de la figure 4, la rainure 6 présente une ouverture rétreinte. De cette façon la rainure 6 peut tre utilisée pour maintenir, par exemple, une languette 10 sur laquelle différentes informations peuvent tre imprimées. La languette 10 peut tre graduée afin de faciliter I e réglage de t'écartement des différentes étagères présentes sur I e montant.  According to another characteristic of the invention and as can be seen from FIG. 4, the groove 6 has a narrowed opening. In this way the groove 6 can be used to hold, for example, a tongue 10 on which different information can be printed. The tongue 10 can be graduated in order to facilitate the adjustment of the spacing of the different shelves present on the upright.
