Description
La présente invention est relative à un dispositif pour assembler des tubes tels que ceux utilisés, notamment, pour réaliser des échafaudages. The present invention relates to a device for assembling tubes such as those used, in particular, for making scaffolding.
De nombreux dispositifs ont déjà été proposés mais ils présentent tous l'inconvénient de nécessiter l'utilisation d'outils pour réaliser le montage ou le démontage de l'échafaudage. Many devices have already been proposed, but they all have the drawback of requiring the use of tools for mounting or dismounting the scaffolding.
Parmi ces dispositifs, il faut citer ceux qui comportent un organe d'accrochage, fixé à chacune des extrémités du tube devant constituer une traverse, coopérant avec un autre organe fixé sur le tube devant constituer un montant. De ce fait, chaque montant présente un certain nombre d'organes d'accrochage régulièrement espacés. Among these devices, mention should be made of those which comprise a fastening member, fixed to each end of the tube which must constitute a cross member, cooperating with another member fixed to the tube which must constitute an upright. As a result, each upright has a number of regularly spaced hooking members.
Le dispositif de l'invention est du genre de ceux décrits ci-dessus et il est remarquable en ce que l'organe d'accrochage fixé sur le montant est constitué par une galette circulaire comportant un bourrelet périphérique ménageant autour du tube une rainure périphérique et en ce que l'organe d'accrochage fixé sur les traverses se présente sous la forme d'une mâchoire dont le mors supérieur est susceptible de se coincer dans la rainure précitée en prenant appui, d'une part, contre le tube et, d'autre part, contre le flan évasé de ladite rainure. The device of the invention is of the type described above and it is remarkable in that the attachment member fixed to the upright is constituted by a circular wafer comprising a peripheral bead forming around the tube a peripheral groove and in that the fastening member fixed on the crosspieces is in the form of a jaw, the upper jaw of which is capable of being wedged in the aforementioned groove by bearing, on the one hand, against the tube and, d on the other hand, against the flared blank of said groove.
Selon une autre caractéristique de l'invention chaque mâchoire est pourvue d'un dispositif assurant le verrouillage automatique de cette dernière sur la galette correspondante. According to another characteristic of the invention, each jaw is provided with a device ensuring the automatic locking of the latter on the corresponding wafer.
L'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 verticale montrant une mâchoire conforme à l'invention fixée sur une traverse;
-la figure 2 est une vue en coupe verticale montrant une galette fixée sur un montant;
-la figure 3 est une vue en coupe verticale montrant un montant et une traverse assemblés à l'aide du dispositif de l'invention;
-la figure 4 est une vue, analogue à celle 1, montrant une
particularité du dispositif de verrouillage;
-la figure 5 est la vue de dessous de la figure 3, L'organe de
verrouillage n'étant pas représenté;
-la figure 6 est une vue partielle et à plus grande échelle
montrant un détail non représenté sur les autres figures.The invention will be better understood from the description which follows made with reference to the accompanying drawings by way of indicative example only, in which
FIG 1 is a vertical sectional view showing a jaw according to the invention fixed on a crosspiece;
FIG 2 is a vertical sectional view showing a wafer fixed to an upright;
FIG. 3 is a view in vertical section showing an upright and a cross member assembled using the device of the invention;
FIG. 4 is a view, similar to that 1, showing a
particularity of the locking device;

lock not being shown;
FIG. 6 is a partial view on a larger scale
showing a detail not shown in the other figures.
Le problème posé consiste à assembler, de façon rigide et sans
l'aide d'outil, deux tubes 1 et 2. Le tube 1 constitue l'un des montants
d'un échafaudage tubulaire tandis que celui 2 forme l'une des traverses.The problem is to assemble, rigidly and without
using the tool, two tubes 1 and 2. Tube 1 constitutes one of the uprights
of a tubular scaffolding while that 2 forms one of the crosspieces.
Selon l'invention, on fixe sur les montants, aux emplacements
devant recevoir les traverses 2, des galettes 3. Chaque galette, qui est
fixée par exemple par soudage, présente un bourrelet périphérique 4
ménageant sur sa face supérieure, au moins, et en coopération avec le
tube 1, une rainure circulaire 5. De préférence ,et pour des raisons qui
apparaîtront plus moins la galette est symétrique par rapport à son plan
médian qui est perpendiculaire à l'axe du tube 1.Le flan 6 interne de la rainure s'évase vers l'extérieur et constitue une portée conique.According to the invention, the uprights are fixed at the locations
having to receive the sleepers 2, pancakes 3. Each pancake, which is
fixed for example by welding, has a peripheral bead 4
sparing on its upper side, at least, and in cooperation with the
tube 1, a circular groove 5. Preferably, and for reasons which
will appear more less the pancake is symmetrical with respect to its plane
median which is perpendicular to the axis of the tube 1. The internal blank 6 of the groove flares outwards and constitutes a conical bearing.
L'organe d'accrochage fixé sur les traverses 2 est constitué par un
manchon 7, soudé par exemple à chacune des extrémités de la traverse,
présentant une fente 8 à son extrémité délimitant deux mors fixes 9 et
10 respectivement supérieur et inférieur. La largeur de la fente 8 est
bien supérieure à l'épaisseur de la galette 3.The attachment member fixed to the crosspieces 2 is constituted by a
sleeve 7, welded for example at each end of the cross-member,
having a slot 8 at its end defining two fixed jaws 9 and
10 respectively upper and lower. The width of the slot 8 is
much greater than the thickness of the wafer 3.
Les mors 9 et 10 se recourbent en 11, à l'opposé l'un de l'autre,
pour former une surface d'appui, perpendiculaire à l'axe du manchon 7,
Le mors 9 se raccorde au manchon 7 par l'entremise d'une partie oblique
12 susceptible de coopérer avec le flan 6 de la rainure 5 de la galette 3.Jaws 9 and 10 bend at 11, opposite each other,
to form a bearing surface, perpendicular to the axis of the sleeve 7,
The jaw 9 is connected to the sleeve 7 through an oblique part
12 capable of cooperating with the blank 6 of the groove 5 of the wafer 3.
De cette façon, I'ensemble 11-9-12 se comporte à l'instar d'un coin et
se bloque dans la rainure 5 (fig.3). La surface 11 inférieure, qui est
située dans le prolongement de celle supérieure, contribue à assurer la
stabilité de l'assemblage.In this way, the set 11-9-12 behaves like a wedge and
locks in groove 5 (fig.3). The lower surface 11, which is
located in the extension of the upper one, contributes to ensuring the
stability of the assembly.
Le dispositif décrit ci-dessus est complété par un organe de
verrouillage automatique. The device described above is completed by a
automatic locking.
Dans la fente 8 s'étend l'extrémité 13 d'une clavette 14 guidée dans un logement 15 du mors 10. La pénétration de la clavette 14 est limitée par une tête 16. La clavette 14 peut être déplacée selon une direction qui s'étend obliquement par rapport à l'axe du manchon 2,comme montré sur les dessins. In the slot 8 extends the end 13 of a key 14 guided in a housing 15 of the jaw 10. The penetration of the key 14 is limited by a head 16. The key 14 can be moved in a direction which is extends obliquely to the axis of the sleeve 2, as shown in the drawings.
La clavette 14 présente une lumière 17 traversée par une goupille 18 fixe. Dans la lumière 17 est loge un ressort 19 (voir figure 6) présentant, à une extrémité, une spire relevée 20 traversée par la goupille 18. Dans la position représentée sur la figure 6, qui correspond à la figure 1, le ressort 19 est légérement comprimé entre le fond de la lumière 17 et la goupille 18. The key 14 has a lumen 17 through which a fixed pin 18 passes. In the slot 17 is housed a spring 19 (see FIG. 6) having, at one end, a raised turn 20 traversed by the pin 18. In the position shown in FIG. 6, which corresponds to FIG. 1, the spring 19 is slightly compressed between the bottom of the light 17 and the pin 18.
La partie externe du bourrelet 4 est usinée pour former deux surfaces coniques 21 délimitant deux troncs de cône opposés par leur base. The external part of the bead 4 is machined to form two conical surfaces 21 delimiting two truncated cones opposite by their base.
Si, à partir de la position représentée sur la figure 1, on engage les mors sur la galette 3, I'extrémité 13 de la clavette 14 rencontre la surface 21 inférieure et sescamote en comprimant le ressort 19. If, from the position shown in FIG. 1, the jaws are engaged on the wafer 3, the end 13 of the key 14 meets the lower surface 21 and is retracted by compressing the spring 19.
Lorsque les surfaces 11 sont en appui contre le tube 1, I'ensemble 119-12 pénètre dans la-rainure 5 de la galette. Dans cette position,
I'extrémité 13 de la clavette est située derrière le bourrelet 4 et le ressort 19 se détend ce qui a pour effet d'appliquer l'extrémité de la clavette contre le flan 6 de la rainure 5 inférieure.Les tubes 1 et 2 sont assemblés et l'assemblage est verrouillé.When the surfaces 11 are pressed against the tube 1, the assembly 119-12 enters the groove 5 of the wafer. In this position,
The end 13 of the key is located behind the bead 4 and the spring 19 relaxes which has the effect of applying the end of the key against the blank 6 of the lower groove 5. The tubes 1 and 2 are assembled and the assembly is locked.
Pour déverrouiller l'assemblage et permettre le retrait de la traverse 2 il faut exercer, manuellement, une traction sur la tête 16 de la clavette 14. To unlock the assembly and allow the withdrawal of the cross-member 2 it is necessary to exert, manually, a traction on the head 16 of the key 14.
En vue de certaines manipulations il peut être avantageux de maintenir la clavette 14 escamotée à l'intérieur de son logement. In view of certain manipulations it may be advantageous to keep the key 14 retracted inside its housing.
A cet effet, le chant 22 de la clavette 14 présente une échancrure 23 formant un cran 24 (fig.6).De cette façon, en exerçant une traction sur la clavette il est possible, après l'avoir fait pivoter dans son plan, de placer le cran 24 contre le bord 25 du logement 15 en comprimant le
ressort 19, la clavette occupe alors la position représentée sur la
figure 4. Naturellement, et comme montré sur les dessins, la lumière
est convenablement dimensionnée pour permettre ce pivotement. et
présente un décrochement 26.For this purpose, the edge 22 of the key 14 has a notch 23 forming a notch 24 (fig. 6). In this way, by exerting traction on the key it is possible, after having made it pivot in its plane, place the notch 24 against the edge 25 of the housing 15 by compressing the
spring 19, the key then occupies the position shown on the
figure 4. Naturally, and as shown in the drawings, the light
is suitably sized to allow this pivoting. and
has a setback 26.
Outre le fait que le montage et le démontage peuvent être
effectués sans l'aide d'outil, le dispositif de l'invention présente
l'avantage de permettre la fixation de plusieurs traverses au même
niveau en les disposant, par exemple, en étoile par rapport à l'axe du
tube 1. Cette possibilité ressort tout particulièrement de la figure 5.In addition to the fact that assembly and disassembly can be
performed without the aid of a tool, the device of the invention has
the advantage of allowing the attachment of several sleepers to the same
level by arranging them, for example, in star with respect to the axis of the
tube 1. This possibility is particularly apparent in FIG. 5.
Enfin , il faut noter que le mors comportant la clavette 14 est pourvu d'une protubérance 27 qui a pour fonction de protéger la tête de la clavette lors d'une chute de la traverse. Finally, it should be noted that the jaw comprising the key 14 is provided with a protuberance 27 which has the function of protecting the head of the key during a fall of the cross-member.
