Abstract

The tool has a transparent graduated body (1) and a hollow arm (2) which house a spindle (5). Jaws (3,6) with rims (4,7) are mounted on the ends of the hollow arm and spindle and grip a disk (11) on operating a button (8) attached to the spindle. The button is spring loaded (10) in the direction of jaw opening and has a cursor attached which is read against the graduations.

Description

<Desc/Clms Page number 1>
La présente invention concerne un dispositif pour mesurer l'épaisseur des disques de frein, monter sur tout type de véhicules. <Desc / Clms Page number 1>
The present invention relates to a device for measuring the thickness of the brake discs, mounting on all types of vehicles.

La mesure des disques de frein est traditionnellement effectué à l'aide d'un " Palmer ", ce qui nécessite le démontage de la roue et d'une manutention assez longue. The measurement of brake discs is traditionally carried out using a "Palmer", which requires disassembly of the wheel and fairly long handling.

Le dispositif selon l'invention permet de remédier à ces inconvénients .En effet la mesure de l'épaisseur des disques de frein peut ce faire par l'intérieur du demi train avant du véhicule ou par l'extérieur au travers des ajournements de la jante sans qu'aucuns autres organes ne viennent gêné la mesure . The device according to the invention overcomes these drawbacks. Indeed, the measurement of the thickness of the brake discs can be done from the inside of the front half of the vehicle or from the outside through the rim postponements. without any other organs interfering with the measurement.

Il comporte selon une première caractéristique, d'un corps transparent gradué, en son prolongement d'un bras creux équipé d'un doigt, d'une longueur suffisante pour atteindre le disque de frein et d'une commande par bouton . Ce mécanisme permet le déplacement d'un axe sur lequel est monté un curseur de contrôle qui se déplace dans le corps du dispositif . La traction du bouton agi sur l'axe qui a son extrémité possède un doigt, ce qui permet de pincé le disque de frein entre ses deux doigts .Une lecture peut alors se faire entre le curseur de contrôle et la graduation du corps . According to a first characteristic, it has a graduated transparent body, as an extension of a hollow arm equipped with a finger, of a length sufficient to reach the brake disc and of a command by button. This mechanism allows the movement of an axis on which is mounted a control cursor which moves in the body of the device. The pull of the button acting on the axis which has its end has a finger, which allows to pinch the brake disc between his two fingers. A reading can then be done between the control cursor and the graduation of the body.

Selon des modes particuliers de réalisation - Le corps du dispositif peut être transparent et gradué pour apprécier la mesure indiqué par le curseur. According to particular embodiments - The body of the device can be transparent and graduated to assess the measurement indicated by the cursor.

- Un ressort peut être prévu pour éloigner le doigt monté sur l'axe après la mesure La figure 1 annexé illustre l'invention En référence à ce schéma, le dispositif comporte un corps transparent gradué (1) , en son prolongement un bras creux (2) monté d'un doigt (3) équipé d'une pastille (4), permettant le déplacement d'un axe (5) muni à son extrémité d'un doigt (6) équipé d'une pastille (7), commandé par un bouton (8) pourvu d'un curseur de contrôle (9) repoussé par un ressort (10) maintenu par un bouchon (12). La longueur du corps (1) permet une bonne prise à l'utilisateur pour mettre en contact la pastille (4) sur le disque (11), le déplacement du bouton (8) permet d'approcher par l'intermédiaire de l'axe (5)1e doigt (6) équipé de la pastille (7) qui vient se mettre en appui sur le disque (11). - A spring can be provided to move the finger mounted on the axis after the measurement. The attached FIG. 1 illustrates the invention. With reference to this diagram, the device comprises a graduated transparent body (1), in its extension a hollow arm ( 2) mounted with a finger (3) equipped with a pad (4), allowing the displacement of an axis (5) provided at its end with a finger (6) equipped with a pad (7), controlled by a button (8) provided with a control cursor (9) pushed back by a spring (10) held by a plug (12). The length of the body (1) allows a good grip for the user to bring the patch (4) into contact with the disc (11), the movement of the button (8) makes it possible to approach via the axis (5) 1st finger (6) fitted with the pad (7) which comes to bear on the disc (11).

Une lecture peut se faire entre le curseur de contrôle (9) et la graduation du corps (1).Cette lecture donne une mesure égale à l'épaisseur du disque . A reading can be done between the control cursor (9) and the scale of the body (1). This reading gives a measurement equal to the thickness of the disc.

La longueur du bras (2) ainsi que la faible épaisseur des doigts The length of the arm (2) as well as the thinness of the fingers

(3) et (6) permet d'atteindre le disque de frein (11) sans démontage de la roue et sans que d'autres organes ne gênent la mesure .  (3) and (6) makes it possible to reach the brake disc (11) without removing the wheel and without other members interfering with the measurement.

Dans la forme de réalisation selon le schéma le corps (1) d'une apparence ronde et pourvu d'une rainure (13) suffisamment large et longue , permettant le déplacement du bouton (8). La graduation sur le corps (1) se trouve à quatre-vingt dix degrés de la rainure (13) et cent quatre-vingt degrés pour les doigts (3) et (6) . In the embodiment according to the diagram the body (1) of a round appearance and provided with a groove (13) sufficiently wide and long, allowing the displacement of the button (8). The graduation on the body (1) is ninety degrees from the groove (13) and one hundred and eighty degrees for the fingers (3) and (6).

La structure de ce dispositif sera en grande partie réalisé en matière plastique en plusieurs opérations de moulages et de sur- moulages par injection. The structure of this device will be largely made of plastic material in several injection molding and over-molding operations.

Selon une variante non illustrée, le dispositif peut être conçu avec une lecture de mesure sur écran digitale et un dispositif interne électronique . According to a variant not illustrated, the device can be designed with a measurement reading on a digital screen and an internal electronic device.

A titre d'exemple non limitatif, le dispositif aura des dimensions de l'ordre de 40 cm de longueur et de 2,5 cm de diamètre . By way of nonlimiting example, the device will have dimensions of the order of 40 cm in length and 2.5 cm in diameter.

Le dispositif selon l'invention est particulièrement destiné a la prise de la mesure de l'épaisseur des disques de frein . The device according to the invention is particularly intended for taking the measurement of the thickness of the brake discs.
