Abstract

The device has a tube (1A) with an opening (4) in its end, and another tube insertable in the former tube, where the opening is cut in the form of a saw with teeth of 4 millimeter height. The former tube has a locking ring (3) that locks the former tube in the latter tube. The ends of the tube receive safety endfittings (5) made of natural rubber, and are protected by the endfittings. The tubes have openings (6) for providing evacuation of sawdust.

Description

La présente invention concerne un dispositif pour fabriquer une sphèreThe present invention relates to a device for manufacturing a sphere

parfaite en bois à partir d'un morceau de bois de forme parallélépipédique serré dans le mors d'un tour à bois. Jusqu'à présent ces sphères sont traditionnellement fabriquées àl'aide de plusieurs 5 gouges mais avec un résultat plus ou moins aléatoire. perfect in wood from a piece of wood of parallelepiped shape clamped in the jaw of a wood lathe. Hitherto these spheres are traditionally manufactured using several gouges but with a more or less random result.

Le dispositif selon l'invention permet de remédier à cet inconvénient, il comporte en effet selon une première caractéristique un tube en acier (3) d'une épaisseur de 1,5 mm et d'un diamètre interne de 25 mm sur lequel est fixé un collier (2) qui 10 permet le serrage d'un 2e tube emboîté à l'intérieur du le. Ce 2e tube permet la fabrication de deux sphères, d'un coté de 22 mm et de l'autre de 19 mm. Selon des modes particuliers de réalisation, avec le le tube on réalise une sphère de 25 mm. Avec le 2e on fabrique 2 sphères, l'une de 22 mm à un embout, et de 19 mm à l'autre. 15 Les dessins annexés illustrent l'invention : La figure 1 représente le premier tube (1) avec collier de serrage (2) et la bague de serrage (3) et poignée de maintien (8) qui assure la sécurité, l'orifice (4) étant découpé en forme de scie avec des dents de 4 mm de hauteur et un biseau de 7 mm, protégé au repos par un embout en caoutchouc (5), a 2,5 cm du haut des dents, il est prévu 3 trous (6) de 5 mm pour 20 l'évacuation des sciures. The device according to the invention overcomes this drawback, it in fact comprises according to a first characteristic a steel tube (3) with a thickness of 1.5 mm and an internal diameter of 25 mm on which is fixed a collar (2) which allows the clamping of a 2nd tube fitted inside the le. This 2nd tube allows the manufacture of two spheres, one side of 22 mm and the other of 19 mm. According to particular embodiments, with the tube, a 25 mm sphere is produced. With the 2nd we make 2 spheres, one of 22 mm at one end, and of 19 mm at the other. The accompanying drawings illustrate the invention: Figure 1 shows the first tube (1) with clamping collar (2) and the clamping ring (3) and retaining handle (8) which provides security, the orifice ( 4) being cut in the shape of a saw with teeth 4 mm high and a bevel of 7 mm, protected at rest by a rubber tip (5), 2.5 cm from the top of the teeth, 3 holes are provided (6) of 5 mm for the removal of sawdust.

La figure 2 décrit : le 2" tube (1) d'une épaisse de 1,5 mm qui comporte des dents de chaque coté (4) et un 'rétrécissement d'un coté, afin d'effectuer une sphère parfaite d'une plus petite dimension. Ce tube se retourne serrer par le collier (2) 25 c'est extremitees son protégées au repos par des embouts en caoutchouc (5), on retrouve les 2 orifices (6) pour l'évacuation des sciures. Figure 2 describes: the 2 "tube (1) with a thickness of 1.5 mm which has teeth on each side (4) and a 'narrowing on one side, in order to make a perfect sphere of Smaller dimension This tube is turned over and tightened by the collar (2) 25 its ends are protected at rest by rubber end pieces (5), there are the 2 orifices (6) for the evacuation of sawdust.

La figure 3 décrit la poignée de maintien (8) pour conduire le mouvement de rotation lors de la fabrication de boules plus grosses, avec sa bague de serrage (3. Figure 3 depicts the retaining handle (8) for driving the rotational movement when making larger balls, with its clamping ring (3.

30 En référence à ces dessins, le dispositif comporte 2 tubes s'emboîtant l'un dans l'autre, chaque extrémité protégée au repos par un embout de caoutchouc, ( la partie permettant la fabrication de la boules, la plus petite étant protégée par l'insertion dans le plus grand). Le grand tube est muni d'une poignée de maintien (8) permettant d'effectuer le mouvement de rotation lors de l'utilisation de cette 35 gouge (boucher) sur le tour à bois et d'un levier de serrage (2) qui maintient le tube interne. A titre d'exemple non limitatif, cette gouge permet la fabrication de boules en bois de 1 à 10 cm de diamètre. Pour fabriquées des plus grosses boules, il est prévu une poignée (8) pour conduire le mouvement de rotation.With reference to these drawings, the device comprises 2 tubes fitting one into the other, each end protected at rest by a rubber tip, (the part allowing the manufacture of the ball, the smaller one being protected by insertion into the larger one). The large tube is provided with a support handle (8) allowing the rotation movement to be carried out when using this 35 gouge (butcher) on the wood lathe and a clamping lever (2) which maintains the inner tube. By way of non-limiting example, this gouge allows the manufacture of wooden balls from 1 to 10 cm in diameter. For larger balls, a handle (8) is provided to drive the rotational movement.

40 Le dispositif selon l'invention est particulièrement destiné à la fabrication de boules 5 en bois parfaitement sphérique à usage divers : jeux, bijoux, poignées de meubles, etc....40 The device according to the invention is particularly intended for the manufacture of perfectly spherical wooden balls 5 for various uses: games, jewelry, furniture handles, etc.
