BOYAU EN CAOUTCHOUC.
La présente invention a pour objet un nouveau boyau en caout- chouc, particulièrement avantageuxo
Il est connu d'augmenter la-rigidité des boyaux en caoutchouc à l'égard des flexions par une augmentation du moment d'inertie de la sur- face transversale perpendiculaire à l'axe, en formant le boyau avec des ner-- vures longitudinales faisant saillie vers l'extérieur et disposées à un certain écartement l'une de l'autreo Un tel profil présente cependant l'in- convénient qu'il se forme de cette manière des canaux ou évidements longitu- dinaux aptes à recevoir des saletés, plus spécialement à leurs bords infé- rieurs, en rendant ainsi plus difficile le maintien à l'état propre du boyau et en influençant d'une manière défavorable sa valeur d'usage.
Le boyau en caoutchouc suivant la présente invention ne présen- te pas cet inconvénient car sa périphérie constitue un polygone à côtés é- gaux ou inégaux, par exemple un polygone à 12 côtés, ou à 6 côtés, à 5 cô- tés, etc.
Grâce à cette conformation, on obtient d'un côté une augmenta- tion du moment d'inertie de la section transversale perpendiculaire à l'axe, et on évite les évidements ou canaux pouvant recevoir des saletés.
Quant au nombre de côtés du polygone à choisir, cela dépendra des nécessités de chaque cas particulier.
Dans le dessin ci-joint, on a montré schématiquement et en coupe un boyau en caoutchouc suivant l'invention d'après- plusieurs modes de réali- sation.

Fig.-1 par exemple montre un boyau dont la section droite est constitùée en périphérie par un polygone à 12 côtés égaux. Fig. 2 montré un boyau dont là section droite est un polygone à 8 cotés égaux, et la fi- gure 3 montre un boyau dont.la section droite est un hexagone irrégulier.

RUBBER HOSE.
The present invention relates to a novel rubber hose, which is particularly advantageous.
It is known to increase the stiffness of rubber casings against bending by increasing the moment of inertia of the transverse surface perpendicular to the axis, by forming the casing with longitudinal ribs. projecting outwardly and arranged at a certain spacing from one another. However, such a profile has the disadvantage that in this way longitudinal channels or recesses capable of receiving dirt are formed, more especially at their lower edges, thus making it more difficult to keep the casing clean and adversely affecting its use value.
The rubber hose according to the present invention does not have this disadvantage because its periphery constitutes a polygon with equal or unequal sides, for example a polygon with 12 sides, or a 6-sided, 5-sided polygon, etc.
Thanks to this conformation, one obtains on the one hand an increase in the moment of inertia of the transverse section perpendicular to the axis, and recesses or channels which may receive dirt are avoided.
As for the number of sides of the polygon to choose, it will depend on the needs of each particular case.
In the accompanying drawing, there is shown schematically and in section a rubber hose according to the invention according to several embodiments.
<Desc / Clms Page number 2>
Fig.-1 for example shows a hose whose cross section is formed at the periphery by a polygon with 12 equal sides. Fig. 2 shows a gut whose cross section is a polygon with 8 equal sides, and FIG. 3 shows a gut whose cross section is an irregular hexagon.
