"Collier de serrage Il
L'invention se rapporte à un collier de serrage qui sert plus particulièrement à relier temporairement des tubes ou organes tubulaires utilisés dans les échafaudages ou constructions analogues.
On connaît des types variés de colliers de ce genre, constitués en général par deux manchons demi-cylindriques reliés l'un à l'autre de manière amovible . Un inconvénient de ces manchons réside dans le fait que les tubes, en parti- culier s'ils sont relativement mous, subissent une déforma- et tion sous l'effet d'une charge assez forte/tendent à glisser par rapport aux colliers. Un tel relâchement dans le collier étant très dangereux, on a essayé de supprimer l'inconvé-
<Desc/Clms Page number 2>
nient précité en ménageant sur les parois internes du manchon cylindrique des rainures et des saillies dans les- quelles peuvent s'adapter des saillies correspondantes de l'organe tubulaire . Mais la construction devient ainsi très coûteuse, puisque en plus des manchons, il est né- cessaire d'usiner séparément les tubes à relier.
La présente invention permet d'éliminer les inconvé- nients précités en réalisant une construction dans la- quelle le tube, au lieu d'être bloqué par deux pièces seulement, est bloqué par trois segments disposés de façon à peu près uniforme sur le pourtour de l'organe tubulaire.
Le collier conforme à l'invention comprend un corps principal pourvu de deux mâchoires pivotées de chaque côté du corps et susceptible de se serrer l'une contre l'autre pour bloquer entre elles le tube, le corps propre- ment dit portant lui-même un troisième segment de blocage.
Sur les dessins annexés, on a représenté divers types de colliers conformes à l'invention.
Les figures 1 à 3 montrent en coupe un collier simple avec divers types d'organes de liaison pour les deux mâchoires.
La figure ô 4 montre un collier double pour relier deux tubes parallèles.
La figure 5 montre un collier double pour relier deux tubes à angle droit l'un avec l'autre.
Si l'on se reporte aux dessins, le collier représenté sules figures 1 à 3 se compose d'un corps 1 pourvu à chaque extrémité d'articulations 2 ou 2a. La partie moyenne du corps 1 a la forme d'un segment de cylindre-S1 qui constitue l'un des trois segments prévus pour serrer un tube.
Dans les articulations 2 et 2a sont montés, avec un léger jeu, les pivots 3 et 3a des deux mâchoires 4 et 4a. Les
<Desc/Clms Page number 3>
mâchoires 4 et 4a portent chacune un autre segment S2 ou S3 et peuvent être serrées l'une contre l'autre au moyen d'un organe de liaison qui peut être un boulon de tension 5, comme le montre la figure 1, un boulon com- presseur 5a, comme le montre la figure 2, ou un mécanisme à levier 5b comme le montre la figure 3.
Pour dégager le collier, il suffit par suite de des- serrer l'organe de liaison unique précité et de faire tourner vers l'extérieur les mâchoires 4 et 4a autour de leurs pivots 3 et 3a.
Sur la figure 4, qui montre un collier destiné à relier deux tubes parallèles, le corps 6 est commun aux deux moitiés du collier et porte à ses angles quatre articulations 3, 3a, 3b, 3c, pour le montage à pivot de quatre mâchoires.
Dans la réalisation de la figure 5, le corps 7 est également commun aux deux paires de mâchoires, mais il est disposé de façon que les axes des tubes à relier puissent former entre eux l'angle voulu, c'est-à-dire un angle droit.
Le diamètre des articulations 2 et 2a est toujours un peu plus grand que le diamètre des pivots qui y sont montés, de sorte que les deux mâchoires puissent être incli- nées légèrement l'une par rapport à l'autre. Sous l'effet d'une lourde charge, le corps 1 tend à glisser le long du tube . La position inclinée des mâchoires accroît sensi- blement l'effet de serrage sur le tube.
Le serrage très efficace obtenu au moyen des trois segments suivant l'invention réduit considérablement la distorsion de l'organe tubulaire . Etant donné que les mâchoires occupent en même temps une position inclinée l'une par rapport à l'autre, le tube est complètement bloqué même si l'organe de liaison n'est que modérément serré. En outre, le collier suivant l'invention n'exerce
<Desc/Clms Page number 4>
pas la moindre action nuisible sur la surface du tube, et ce dernier n'est pas déformé quand de lourdes charges doivent être transmises par le collier.

"Hose clamp It
The invention relates to a clamp which serves more particularly to temporarily connect tubes or tubular members used in scaffolding or similar constructions.
Various types of collars of this type are known, generally consisting of two half-cylindrical sleeves connected to one another in a removable manner. A disadvantage of these sleeves is that the tubes, especially if they are relatively soft, undergo deformation under the effect of a fairly strong load / tend to slide relative to the collars. Since such a slack in the collar is very dangerous, an attempt has been made to eliminate the inconvenience.
<Desc / Clms Page number 2>
deny the aforementioned by providing on the internal walls of the cylindrical sleeve grooves and projections in which can fit corresponding projections of the tubular member. But the construction thus becomes very expensive, since in addition to the sleeves, it is necessary to machine the tubes to be connected separately.
The present invention makes it possible to eliminate the aforementioned drawbacks by providing a construction in which the tube, instead of being blocked by two parts only, is blocked by three segments arranged more or less uniformly around the periphery of the tube. the tubular organ.
The collar according to the invention comprises a main body provided with two jaws pivoted on each side of the body and capable of tightening against each other to block the tube between them, the body itself carrying itself. a third blocking segment.
Various types of collars in accordance with the invention have been shown in the accompanying drawings.
Figures 1 to 3 show in section a simple collar with various types of connecting members for the two jaws.
Figure ô 4 shows a double collar for connecting two parallel tubes.
Figure 5 shows a double collar for connecting two tubes at right angles to each other.
If we refer to the drawings, the collar shown in Figures 1 to 3 consists of a body 1 provided at each end of joints 2 or 2a. The middle part of the body 1 has the shape of a cylinder segment-S1 which constitutes one of the three segments provided for clamping a tube.
In the joints 2 and 2a are mounted, with a slight play, the pivots 3 and 3a of the two jaws 4 and 4a. The
<Desc / Clms Page number 3>
jaws 4 and 4a each carry another segment S2 or S3 and can be clamped against each other by means of a connecting member which can be a tension bolt 5, as shown in figure 1, a bolt com - presser 5a, as shown in figure 2, or a lever mechanism 5b as shown in figure 3.
To release the collar, it is therefore sufficient to loosen the aforementioned single connecting member and to rotate the jaws 4 and 4a outwards around their pivots 3 and 3a.
In FIG. 4, which shows a collar intended to connect two parallel tubes, the body 6 is common to the two halves of the collar and carries at its angles four articulations 3, 3a, 3b, 3c, for the pivot mounting of four jaws.
In the embodiment of FIG. 5, the body 7 is also common to the two pairs of jaws, but it is arranged so that the axes of the tubes to be connected can form between them the desired angle, that is to say a right angle.
The diameter of the joints 2 and 2a is always a little larger than the diameter of the pivots mounted therein, so that the two jaws can be tilted slightly relative to each other. Under the effect of a heavy load, the body 1 tends to slide along the tube. The inclined position of the jaws significantly increases the clamping effect on the tube.
The very effective clamping obtained by means of the three segments according to the invention considerably reduces the distortion of the tubular member. Since the jaws at the same time occupy an inclined position with respect to each other, the tube is completely blocked even if the connecting member is only moderately tightened. In addition, the collar according to the invention does not exert
<Desc / Clms Page number 4>
no harmful action on the surface of the tube, and the tube is not deformed when heavy loads have to be transmitted through the clamp.
