Description

Dispositif de réglage de tension de tige de selle à suspension La présente invention est relative à un dispositif de réglage de tension de tige de selle à suspension. Plus particulièrement, l'invention concerne le réglage de la dureté de la suspension de selles de cycles et véhicules similaires tels aux véhicules à deux roues reliées par un cadre. Les dispositifs de réglage de tension de tige de selle connus actuellement contenu dans la tige comprennent un moyen de compression et réglage du type à ressort intérieur hélicoïdal relié par partie inférieure à une pièce de réglage formant une vis creuse disposée dans le tube. Ces dispositifs connus exigent pour le réglage de la tension les opérations suivantes : - démontage de la tige (avec la selle), - utilisation d'une clé à alêne (outil nécessaire), -- l'action de vissage et dévissage de la pièce de réglage disposée en partie inférieure pour comprimer plus ou moins le ressort. Ceci pour arriver à une certaine dureté, - tester la dureté, Si nécessaire recommencer le cycle jusqu'à arriver au bon réglage. Ainsi, ce réglage est long et répétitif ; ce qui est complexe et exige • l'emport d'un outil adapté. L'emport de matériel est un inconvénient pour un cycliste qui roule sur la route et souhaite adapter la dureté de la selle par un réglage de tension par exemple au moment où il arrive sur un chemin forestier. Le problème posé à la présente invention consiste notamment à pallier ces inconvénients et permettre le réglage par simple rotation de la tige de selle en tournant la selle. Ceci est obtenu en évitant l'utilisation d'outils et le démontage de la tige et en présentant de plus une facilité de réglage certaine, car la selle forme un bras de levier. A cet effet le dispositif selon l'invention comprend une tige munie d'une collerette, reliée à au moins un moyen d'actionnement de deux expandeurs coopérant entre eux, le moyen d'actionnement comprenant au moins une collerette surmontée d'une pièce percée coulissant sur la tige au-dessus des expandeurs. Ladite pièce présentant des crans sur sa face inférieure coopérant avec une rondelle crantée qui présente une patte coulissant dans un trou oblong prévu dans l'expandeur supérieur en partie supérieure ; en partie supérieure la tige comprend une butée dépassant du passage formé par le creux de la vis du moyen de réglage interdisant la sortie de la tige qui' comprend un moyen d'entraînement en rotation et un moyen de solidarisation de la selle. Suivants d'autres caractéristiques du dispositif selon l'invention : la tige présente un filetage inférieur traversant la base inférieure de l'expandeur inférieur ; - la base inférieure de l'expandeur inférieur est muni d'un trou taraudé ; - la face inférieure de la rondelle crantée présente une partie lisse ; - le moyen d'entraînement en rotation de la tige comprend des faces planes formées sur la tige ; - la tige est au moins en partie hexagonale. - la pièce présentant des crans sur sa face inférieure présente un trou traversant hexagonal ajusté coulissant sur la tige ; - la butée est une vis liée à la partie supérieure de la tige de liaison, de tête de diamètre supérieur au creux de la vis de réglage ; - un rétrécissement est réalisé au niveau de l'ouverture inférieure de là tige de selle emprisonnant la vis de réglage, interdisant la possibilité de sortir. L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à des modes de réalisation préférés, donnés à titre d'exemples non limitatifs, et expliqués avec référence aux dessins schématiques annexés, dans lesquelles : - La Fig. 1 représente une vue en coupe verticale d'un dispositif de réglage de tension selon un mode de réalisation préféré de l'invention monté dans une tige de selle à suspension ; - La Fig. 2 représente une vue en élévation du dispositif selon l'invention représenté sur la Fig. 1 ; - La Fig. 3 représente une vue en élévation du dispositif selon l'invention dans la variante sans le ressort d'arrêt. Le dispositif représenté sur les figures comprend une tige hexagonale a qui actionne par rotation des expandeurs b et b'. Une pièce crantée c située au-dessus des expandeurs b et b' vient au contact d'une rondelle d elle même crantée sur sa partie supérieure afin de permettre le vissage et d'interdire le dévissage. Cette rondelle d est munie d'une patte coulissant dans l'oblong réalisé dans la partie supérieure de l'expandeur supérieur b' qui contribue à interdire le dévissage. La pièce crantée c coulisse sur la tige de liaison a grâce à un trou traversant de forme hexagonal sensiblement égal et de préférence légèrement supérieure au diamètre de la tige a. Par rotation de cette tige a, le double expandeur formé par les expandeurs coopérant entre eux b et b' se bloque dans un tube e de cadre de vélo. L'extrémité inférieure de cette tige hexagonale a est munie d'un filetage traversant la base inférieure de l'expandeur inférieur b, cette dernière présente un trou taraudé. Le point d'ancrage inférieur comprend les deux expandeurs coopérant entre eux b et b'. La partie supérieure de la tige de liaison a hexagonale traverse la vis creuse f positionnée à la base des tiges de selles suspendues. Ce passage permet de placer une clé hexagonale dans son utilisation normale afin de visser ou de dévisser la vis qui a pour fonction de compresser plus ou moins le ressort g du système de tige à suspension. La partie supérieure de la tige de liaison hexagonale a est munie d'une vis d de diamètre supérieur au passage de la vis creuse de réglage f afin d'interdire à la tige de pouvoir ressortir. La tige de liaison hexagonale a peut ainsi circuler intérieurement dans la tige de selle i à travers la vis creuse f de la base de la tige de selle jusqu'à la partie supérieure de la tige de selle. La vis creuse f, à la base et à l'intérieur de la tige de selle i peut être actionnée jusqu'au plus haut du taraudage intérieur dans la tige de selle. Sur la partie basse du taraudage, une frappe est effectuée sur la tige de selle ce qui forme un rétrécissement h afin d'interdire à la vis creuse f de pouvoir être dévissée totalement et être sortie de la tige de selle i. De ce fait, le réglage de la suspension se fera uniquement en tournant la selle positionnée sur la tige de selle à droite ou à gauche selon l'effet recherché. Ce système interdit également de désolidariser la tige de selle du tube de selle du cadre du vélo et interdit de ce fait le vol de la tige avec la selle. Un ressort j fixé en partie supérieure à une deuxième collerette de la tige a maintient par pression sur la pièce c la coopération des crans entre la pièce c et la rondelle d. En variante et afin de pouvoir désolidariser par retournement du vélo la pièce crantée c de la rondelle d, la tige hexagonale a ne comprend pas de ressort placé directement au-dessus de la pièce crantée c. Suivant d'autres variantes d'exécution, le rétrécissement h est formé par un circlips ou un point de soudure. Il ressort de ce qui précède que les avantages du dispositif selon l'invention sont nombreux : il est simple, robuste, facile à installer, il ne nécessite aucune modification ou moyen d'adaptation particulier sur les tubes employés dans la fabrication de cycles, aucun percement n'est nécessaire. Un autre avantage est certainement son efficacité puisqu'il est installé à l'intérieur des tubes et donc non accessible. L'invention est applicable à différents types de véhicules notamment les véhicules à deux roues. Il peut constituer un produit de première monte pour les fabricants entres autres de cycles et également de vente autonome, ne nécessitant aucune modification du tube de cadre pour son installation. Bien que l'invention ait été décrite en liaison avec des structures particulières, elle n'y est nullement limitée. De nombreuses variantes restent possibles, notamment du point de vue de la construction des divers éléments par substitution d'équivalents techniques, sans sortir pour autant du domaine de l'invention. Les combinaisons des différentes réalisations représentées sur les dessins ou décrites ci-dessus ne sortent pas du cadre de l'invention. Signes de références a tige b expandeur supérieur b' expandeur inférieur c pièce crantée d rondelle e tube f vis creuse g ressort de suspension h rétrécissement i tige de selle j ressort de la tige Les signes de références insérés après les caractéristiques techniques mentionnées dans les revendications ont pour seul but de faciliter la compréhension de ces dernières et n'en limitent aucunement la portée. The present invention relates to a device for adjusting the suspension seatpost tension. More particularly, the invention relates to the adjustment of the hardness of the suspension of saddles for cycles and similar vehicles such as two-wheeled vehicles connected by a frame. The known seat post tension adjustment devices currently contained in the post include a compression and adjustment means of the helical internal spring type connected by the lower part to an adjustment piece forming a hollow screw placed in the tube. These known devices require the following operations for adjusting the tension: - disassembly of the rod (with the saddle), - use of an awl wrench (tool required), - the action of screwing and unscrewing the part adjustment arranged in the lower part to more or less compress the spring. This to arrive at a certain hardness, - test the hardness, If necessary repeat the cycle until arriving at the correct setting. Thus, this adjustment is long and repetitive; which is complex and requires • the use of a suitable tool. Carrying equipment is a disadvantage for a cyclist who rides on the road and wants to adapt the hardness of the saddle by adjusting the tension, for example when he arrives on a forest path. The problem posed by the present invention consists in particular in overcoming these drawbacks and allowing adjustment by simple rotation of the seatpost by turning the saddle. This is achieved by avoiding the use of tools and the dismantling of the rod and also presenting a certain ease of adjustment, since the saddle forms a lever arm. To this end, the device according to the invention comprises a rod provided with a collar, connected to at least one actuation means of two expanders cooperating with each other, the actuation means comprising at least one collar surmounted by a pierced part. sliding on the rod above the expanders. Said part having notches on its underside cooperating with a notched washer which has a tab sliding in an oblong hole provided in the upper expander in the upper part; in the upper part the rod comprises a stop protruding from the passage formed by the hollow of the screw of the adjustment means preventing the exit of the rod which ' comprises a means for driving in rotation and a means for securing the saddle. Following other characteristics of the device according to the invention: the rod has a lower thread passing through the lower base of the lower expander; - the lower base of the lower expander is provided with a tapped hole; - The underside of the notched washer has a smooth part; the means for driving the rod in rotation comprises flat faces formed on the rod; - the rod is at least partly hexagonal. - The part having notches on its underside has an adjusted hexagonal through hole sliding on the rod; - The stop is a screw linked to the upper part of the connecting rod, with a head of diameter greater than the hollow of the adjustment screw; - A narrowing is carried out at the lower opening of the seat post trapping the adjusting screw, preventing the possibility of going out. The invention will be better understood from the following description, which relates to preferred embodiments, given by way of non-limiting examples, and explained with reference to the appended schematic drawings, in which: - FIG. 1 shows a vertical sectional view of a tension adjustment device according to a preferred embodiment of the invention mounted in a suspension seat post; - Fig. 2 shows an elevational view of the device according to the invention shown in FIG. 1; - Fig. 3 shows an elevational view of the device according to the invention in the variant without the stop spring. The device shown in the figures comprises a hexagonal rod a which actuates the expanders b and b 'by rotation. A notched piece c located above the expanders b and b 'comes into contact with a washer d itself notched on its upper part to allow screwing and to prohibit unscrewing. This washer d is provided with a tab sliding in the oblong produced in the upper part of the upper expander b 'which contributes to preventing unscrewing. The notched part c slides on the connecting rod a through a through hole of hexagonal shape substantially equal and preferably slightly greater than the diameter of the rod a. By rotation of this rod a, the double expander formed by the expanders cooperating with each other b and b 'is blocked in a tube e of the bicycle frame. The lower end of this hexagonal rod a is provided with a thread passing through the lower base of the lower expander b, the latter has a tapped hole. The lower anchoring point comprises the two expanders cooperating with each other b and b '. The upper part of the hexagonal connecting rod crosses the hollow screw f positioned at the base of the suspended seatpost. This passage makes it possible to place a hexagonal key in normal use in order to screw or unscrew the screw which has the function of compressing more or less the spring g of the suspension rod system. The upper part of the hexagonal connecting rod a is provided with a screw d with a diameter greater than the passage of the hollow adjusting screw f in order to prevent the rod from being able to come out. The hexagonal connecting rod a can thus flow internally in the seat post i through the hollow screw f from the base of the seat post to the upper part of the seat post. The hollow screw f, at the base and inside the seatpost i can be actuated up to the top of the internal thread in the seatpost. On the lower part of the thread, a strike is made on the seat post which forms a narrowing h in order to prevent the hollow screw f from being able to be completely unscrewed and to be taken out of the seat post i. Therefore, the suspension adjustment will only be done by turning the saddle positioned on the seatpost to the right or left depending on the desired effect. This system also prohibits detaching the seat post from the seat tube of the bicycle frame and therefore prohibits the theft of the post with the saddle. A spring j fixed in the upper part to a second flange of the rod a maintains by pressure on the part c the cooperation of the notches between the part c and the washer d. As a variant and in order to be able to separate the notched part c from the washer d by turning the bicycle over, the hexagonal rod a does not include a spring placed directly above the notched part c. According to other alternative embodiments, the narrowing h is formed by a circlip or a welding point. It follows from the above that the advantages of the device according to the invention are numerous: it is simple, robust, easy to install, it does not require any modification or particular means of adaptation on the tubes used in the manufacture of cycles, no drilling is not necessary. Another advantage is certainly its efficiency since it is installed inside the tubes and therefore not accessible. The invention is applicable to different types of vehicles, in particular two-wheeled vehicles. It can constitute an original equipment product for manufacturers, among others, of cycles and also of independent sale, requiring no modification of the frame tube for its installation. Although the invention has been described in connection with particular structures, it is in no way limited to it. Many variants remain possible, in particular from the point of view of the construction of the various elements by substitution of technical equivalents, without thereby departing from the scope of the invention. The combinations of the various embodiments shown in the drawings or described above do not depart from the scope of the invention. Reference signs a rod b upper expander b 'lower expander c notched piece d washer e tube f hollow screw g suspension spring h shrinking i seatpost j rod spring The reference signs inserted after the technical characteristics mentioned in the claims have the sole purpose of facilitating the understanding of the latter and in no way limit their scope.
