Abstract

The device has a part comprising a variable length (a'), and a diameter (d), and an external part with a diameter (c) and a length (a), where the external part is deformable to the interior of the device. A slot is provided at a specific length of the external part, where the slot is directed to the interior of the device. The length of the part and the length of the external part are provided as a function of the diameter. The diameter of the part corresponds to the diameter of a rod of a seat.

Description

La présente invention est désitinée à rehausser les selles de vélo BMX de toutes tailles pour une utilisation sur route ou sur terrain plat. Éventuellement, la rallonge peut être utilisée pour d'autres vélos. Le vélo BMX a une petite hauteur et la selle est souvent baissée au maximum pour ne pas géner le pilote lors des sauts. La selle sert surtout à se reposer après une course ou en attendant les départs des races. Il est difficile de pédaler avec une petite hauteur de selle. Le dispositif selon l'invention permet de renlédier à cet inconvénient. La selle sera à une hauteur qui correspondra, suivant la taille du pilote, à son 10 entrejambes avec chaussures. Le pilote aura alors une position confortable lors de déplacement sur route ou terrain plat et des exercices de récupération après un entraînement ou une compétition. Les dimensions sont variables en fonction de la tige de selle (accessoire sur lequel est fixé la selle), de la longueur du tube de selle (tube du cadre dans 15 lequel entre la tige de selle), de la longueur des manivelles, et de l'entrejambe du pilote. Le diamètre de la partie b longueur c+5 correspond au diamètre extérieur du tube de selle. Cette partie recevra un collier de serrage, que l'on trouve dans le commerce, permettant le blocage de la tige de selle, grâce à la 20 rainure e qui permet la déformation de la partie b longueur c+5 pour rattraper le jeu, nécessaire, entre le tube de selle et la tige de selle. La longueur de la partie c+5 est fonction du diamètre a. La longueur c est égale à 2,75 a. Le diamètre a' correspond au diamètre de la tige de selle. La partie d est fonction de la longueur du tube de selle, de la tige de selle et 25 de l'entrejambe. Le dessin annexé illustre l'invention. Il représente en coupe partielle et en coupe A-A les différentes formes à réaliser, Le dispositif comprend une pièce, de dimensions variables en fonction de la taille du pilote, du vélo et l'ensemble tige de selle-selle, 30 La fabrication peut être réalisée par usinage au tour à métaux. Une combinaison de plusieurs mode de fabrication peut être envisagée: Par exemple fluotournage, forgeage, rétreinte, extrusion, et usinage. Le dispositif est particulièrement destiné à rehausser la selle des vélos BMX.The present invention is directed to enhancing BMX bike saddles of all sizes for use on road or flat terrain. Optionally, the extension can be used for other bikes. The BMX bike has a small height and the saddle is often lowered to the maximum not to generate the driver during jumps. The saddle is used mainly to rest after a race or waiting for the races to start. It is difficult to pedal with a small seat height. The device according to the invention makes it possible to reduce this disadvantage. The saddle will be at a height that will correspond, depending on the size of the driver, his 10 crotch with shoes. The driver will then have a comfortable position when traveling on road or flat terrain and recovery exercises after a training or competition. The dimensions are variable depending on the seat post (accessory on which the seat is attached), the length of the seat tube (frame tube in which between the seat post), the length of the cranks, and crotch of the pilot. The diameter of the portion b length c + 5 corresponds to the outer diameter of the seat tube. This part will receive a clamp, which is found in the trade, allowing the blocking of the seat post, thanks to the groove e which allows the deformation of the part b length c + 5 to make up the game, necessary , between the seat tube and the seat post. The length of the part c + 5 is a function of the diameter a. The length c is 2.75 a. The diameter a 'corresponds to the diameter of the seat post. Part d is a function of the length of the seat tube, the seat post and the crotch. The accompanying drawing illustrates the invention. It shows in partial section and in section AA the different shapes to be produced. The device comprises a part, of variable dimensions depending on the size of the rider, the bicycle and the saddle-seat assembly. The manufacture can be carried out by metal lathe machining. A combination of several manufacturing methods can be considered: For example spinning, forging, necking, extrusion, and machining. The device is particularly designed to enhance the saddle BMX bikes.
