Abstract

Clamping collar for cylindrical tubes. The subject of the invention relates to the clamping of various cylindrical tubes of all diameters inserted into one another and applies especially to the exhaust pipes of motorised vehicles. This collar consists of a strip of steel 1 which can be moulded by hand, equipped at its ends with welded plates, one pierced with a free passage hole 2, the other pierced with a tapped hole 3. These plates, after shaping the mouldable steel strip around the tubes to be clamped, are connected together by a clamping bolt 4.

Description

La présente invention concerne un dispositif de serrage dit (collier de serrage), de deux tubes cylindriques emmanchés l'un dans l'autre notamment les différents tubes d'échappement mâle et femelle composant la ligne d'échappement d'un véhicule motorisé
Les colliers de serrage existants en la matière prézentent cer tains inconvénients. xe;r mise en place est souvent peu commode.The present invention relates to a so-called clamping device (clamp), of two cylindrical tubes fitted one inside the other, in particular the different male and female exhaust tubes making up the exhaust line of a motor vehicle.
The existing cable ties in this area have certain drawbacks. xe; r installation is often inconvenient.

n effet , certains présentent plusieurs joints de perrage, d'où noeres répétées, et d'autres doivent être mis en place avant montage de la ligne d'échappement. Ils sont, d'autre part, dffti ciles au démontage car ils sont souvent déformés au montage, ou bien. les tubes ont été écrasés au serrage. Par ailleurs certains colliers éxistants ne sont suffisament larges et ne masquent pas les fentes longitudinales ménagées aux e=-tremitês es tubes fem- elles. Ce fait provoque des fuites de gaz. L'objet de l'invention paile ces inconvénients et s'adapte à tous tubes cylindriques emmanchés et de tvus diamètres. n indeed, some have several drilling joints, hence repeated noeres, and others must be put in place before mounting the exhaust line. They are, on the other hand, difficult to dismantle because they are often deformed during assembly, or else. the tubes were crushed when tightened. In addition, certain existing collars are not wide enough and do not hide the longitudinal slots formed at the ends of the female tubes. This fact causes gas to leak. The object of the invention overcomes these drawbacks and adapts to all fitted cylindrical tubes and of larger diameters.

- La figure 1 représente en coupe le dispositif selon l'invention - La figure 2 représente er élévation ce même dispositif.- Figure 1 shows in section the device according to the invention - Figure 2 shows er elevation the same device.

Le collier de serrage, objet de l'invention, se compose d'une ban- de acier pouvant avoir An e épaisseur de 0,10 á 0,18 mm et ne largeur toujours égale aux fentes pratiquées, ce qui permet le moulage la main. -'n, effet cette bande possède une maniabilité telle out elle épouse complètement la partie du tube à serrer.Le collier, composé de la bande acier possède une telle élasticité que celui ci présente l'avantage de Douvoir être enroulé facilement et As en forme à la main autour du tube, et ceci sans aucune manoeuvre supplèmentaire. Cecollier peut également être mis en place après montage complet de la ligne d'échappement. L'autre avantage res- ide dans le fait que cet acier résiste à la corosion et à de hau tes températures, ce qui permet un démontage facile.The clamp, object of the invention, consists of a steel strip which may have a thickness of 0.10 to 0.18 mm and not always equal in width to the slots made, which allows molding by hand. . -'n, effect this band has such maneuverability out it completely hugs the part of the tube to be tightened. The collar, composed of the steel band has such elasticity that it has the advantage of being able to be wound easily and as fit by hand around the tube, and this without any additional maneuver. Cecollier can also be installed after complete assembly of the exhaust line. The other advantage resides in the fact that this steel resists corrosion and high temperatures, which allows easy disassembly.

Dans le dispositif selon l'invention chacune des eemites de la bande acier(1) comporte ,d'une part une platine percee d'un trou libre de passage (2)et d'autre part un trou taraude(3).Ces deux platines sont soudees sur cette bande.In the device according to the invention, each of the eemites of the steel strip (1) comprises, on the one hand a plate pierced with a free passage hole (2) and on the other hand a tapped hole (3). plates are welded on this strip.

dans ce diapositif un boulon de serrage traverse la platine (2) et vient apres mise en forme de la bande d'acier moulable(1 )autour des tubes d'echappement,se visser dans l'autre platine(3).  in this slide, a tightening bolt crosses the plate (2) and after shaping the moldable steel strip (1) around the exhaust tubes, screw into the other plate (3).

Claims (3)

REVENDICATIONS t- Dispositif destiné à serrer les différents tubes d'échappement: mle et femelle emmanches entre eux et constituant la ligne d'échappement caractérisé par une bande acier (1) moulable à la main, et d'une largeur au moins égale aux fentes pratiquées dans les tu bes femelles pour donner plus de souplesse au serrage, évitant ai nsi toute fuite de gaz par ces fentes.t- Device intended to clamp the various exhaust tubes: male and female fittings between them and constituting the exhaust line characterized by a steel band (1) moldable by hand, and of a width at least equal to the slots made in the female tubes to give more flexibility in tightening, thus avoiding any leakage of gas through these slots. 2- DispOsitif suivant la revendication i- selon laquelle chacune des extrémités de la bande acier (i) comporte, d'une part une platine percée d'un trou libre de passage (2) et d'autre part un trou taraudé (3). Ces deux platines sont soudées sur cette bande.2- Device according to claim i - according to which each end of the steel strip (i) comprises, on the one hand a plate pierced with a free passage hole (2) and on the other hand a tapped hole (3) . These two plates are welded to this strip. 3- Dispositif selon 1t revendication 1 et 2, comportant un boulon de serrage qui traverse la platine (2) et qui vient après mise en forme de la bande d'acier moulable (1) autour des tubes d'échappement, se visser dans l'autre platine (3). 3- Device according to 1t claim 1 and 2, comprising a clamping bolt which passes through the plate (2) and which comes after shaping of the castable steel strip (1) around the exhaust tubes, screw into the '' other plate (3).
