Abstract
Description
Il est connu d'utiliser comme collier de serrage pour tuyaux de caoutchouc, ou analogue, un simple fil à ressort en forme de boucle délimitant, à ltétat libre, un cercle de diamètre réduit par rapport au diamètre du tuyau a serrer et qui, sous contrainte produite par le rapprochement de ses extrémités, délimite un cercle de plus grand diamètre permettant le passage libre du tuyau.It is known to use as a clamp for rubber hoses, or the like, a simple spring wire in the form of a loop delimiting, in the free state, a circle of reduced diameter compared to the diameter of the hose to be tightened and which, under stress produced by the bringing together of its ends, delimits a circle of larger diameter allowing the free passage of the pipe.
On connait également des guides dans lesquels on fait passer les tuyaux pour les proteger, en particulier contre une déformation exagérée, meme un risque de déchirure, et qui sont constitués par un simple ressort hélicoidal dont le diamètre intérieur est plus grand que celui du tuyau.Guides are also known in which the pipes are passed to protect them, in particular against exaggerated deformation, even a risk of tearing, and which consist of a simple helical spring whose internal diameter is greater than that of the pipe.
L'invention vise à constituer par une seule et même pièce l'ensemble de ces moyens de serrage et de guidage.The invention aims to constitute by a single piece all of these clamping and guiding means.
A cet effet, l'invention a pour objet un dispositif constitué par un fil à ressort auquel on a donné la forme du collier de serrage décrit plus haut, et qui, à l'une de ses extrémités, se prolonge par une portion intermédiaire jusqu'à l'une des extrémités du ressort hélicoïdal également décrit plus haut.To this end, the subject of the invention is a device constituted by a spring wire to which the shape of the clamp described above has been given, and which, at one of its ends, is extended by an intermediate portion up to 'at one end of the helical spring also described above.
Dans une forme de réalisation préférée, la portion intermédiaire de fil et l'extrémité libre de la partie collier de serrage ont des formes adaptées à l'action manuelle de serrage, p#ar exemple, ont la forme de boucles plates, dont les plans seront avantageusement inclinés l'un par rapport à l'autre. In a preferred embodiment, the intermediate portion of wire and the free end of the clamping part have shapes suitable for manual tightening action, for example, have the form of flat loops, the planes of which will advantageously be inclined with respect to each other.
A titre nullement limitatif, on a représenté au dessin annexé, un exemple de réalisation de dispositif selon l'invention, dessin sur lequel : - la figure 1 est une vue en élévation du dispositif et, - la figure 2 est une vue en bout du dispositif de la fi
gure 1. By way of non-limiting example, there is shown in the accompanying drawing, an embodiment of the device according to the invention, drawing in which: - Figure 1 is an elevational view of the device and, - Figure 2 is an end view of the fi device
gure 1.
Dans l'exemple représenté, le dispositif de l'invention est constitué par un fil d'acier à ressort et destiné à assurer le serrage sur embout et le guidage d'un tuyau de caoutchouc d'un diamètre de 12 mm.In the example shown, the device of the invention consists of a spring steel wire and intended to ensure the clamping on the end piece and the guiding of a rubber hose with a diameter of 12 mm.
Sur la première partie de son développement axial, ce dispositif a la forme d'un ressort hélicoidal 1 d'un diamètre intérieur de 14,5 mm. A partir du point 2 de la dernière spire 3 de la partie ressort l,le fil s'écarte de celle-ci et forme d'abord une boucle 4 ouverte, en U, tracée dans un plan passant sensiblement par l'axe 5 du ressort 1, puis une boucle 6 pratiquement fermée et délimitant un cercle d'un diamètre intérieur de ll-mm, situé dans un plan sensiblement perpendiculaire à l'axe du ressort et qui, vu en bout (fig. 2) apparaît tangent intérieurement à la dernière spire 3 du ressort.On the first part of its axial development, this device has the shape of a helical spring 1 with an internal diameter of 14.5 mm. From point 2 of the last turn 3 of the spring part l, the wire departs from it and first forms an open loop 4, in U, traced in a plane passing substantially through the axis 5 of the spring 1, then a practically closed loop 6 and delimiting a circle with an internal diameter of ll-mm, situated in a plane substantially perpendicular to the axis of the spring and which, seen at the end (fig. 2) appears internally tangent to the last turn 3 of the spring.
Le fil s'écarte ensuite pour former une seconde boucle 7, symétrique de la boucle 4 par rapport au plan axial 8 passant par le point 2. Les plans des deux boucles 4 et 7 font entre eux, ici, un angle d'environ 600. The wire then moves aside to form a second loop 7, symmetrical with the loop 4 with respect to the axial plane 8 passing through the point 2. The planes of the two loops 4 and 7 form an angle of about 600 between them. .
Le rapprochement par serrage des deux boucles 4 et 7 permet d'agrandir la boucle 6 jusqu'au diamètre des spires du ressort 1 et de permettre ainsi le passage du tuyau de caoutchouc jusque dans le ressort de guidage. Dès qu'on cesse d'agir sur les boucles 4, 7, la boucle 6 reprend, par élasticité, son diamètre réduit et assure son rôle de collier de serrage. The bringing together by tightening of the two loops 4 and 7 makes it possible to enlarge the loop 6 to the diameter of the turns of the spring 1 and thus to allow the passage of the rubber hose as far as the guide spring. As soon as we stop acting on the loops 4, 7, the loop 6 resumes, by elasticity, its reduced diameter and fulfills its role as a clamp.
