Description

Dispositif de serrage rapide pour moyeux de cycles. Les moyeux de cycles et notamment de bicyclettes doivent pouvoir eire demontes et remontes tres facilement et tres rapidement par un dispositif manoeizvrable ä la main. Il y a interet ä remplacer les gcrous ou Papillons de serrage de modeles connus, par un dis- positif manoeuvrable dune seule main. Le dis- positif, objet du present brevet, repond a rette caracteristique. Quick clamping device for cycle hubs. The hubs of cycles and in particular of bicycles must be able to be disassembled and reassembled very easily and very quickly by a device that can be operated by hand. There is an interest in replacing the nuts or clamping butterflies of known models, by a device that can be operated with one hand. The device, object of the present patent, responds to this characteristic.

Dans 1e dessin annexe montrant ä titre d'exemple deux formes d'exkution de Finven- tion La fig. 1 montre une vue d'ensemble en coupe.d'un moyeu serre entre les pattes d'un eadre de cycle, ä 1'aide du dispositif etabli selon une Premiere forme d'execution. In the appended drawing showing by way of example two embodiments of the invention, FIG. 1 shows an overall sectional view of a hub clamped between the legs of a cycle frame, using the device established according to a first embodiment.

La fig. 2 montre une vue partielle et en coupe du dispositif etabli suivant une deu- xi6me forme d'execution. fig. 2 shows a partial view in section of the device established according to a second form of execution.

Le moyeu 1 de type connil represente ä la fig. 1 est mnni dun axe 2 peree axialement et traverse par une brocke 3. The connil-type hub 1 shown in FIG. 1 is provided with an axis 2 pierced axially and crossed by a bracket 3.

t1 une extreinite rette broche se bloque Jans une embase 4 dopt elle devient ainsi soli- daire apres montage. Cette embase Porte une Tondelle d'appui 5 appliquee sur la patte 6 du "cadre. A 1'autre extremite, la broche 3 pre- sente iuie Partie filetee 7 qui coopere avec un ecrou forrriant une seeonde embase et portant, un levier B. Une euvette d'appui 19 tourne librement dann une Borge de la seconde em- base de fa@on ä adoueir 1'effort de serrage. L'embase 4 est munie d'un ergot 9 engage dans une rainure presentee ä 1'extremite de faxe. De la sorte, 1'embase 4 peut etre d6 plac6e axialement, mais -se trouve fixee en rotation par rapport ä Faxe 2. Il va de soi que tout autre type d'ergot ou procede connu pour empecher la rotation de 1'embase 4 par rapport ä la patte 6 peut etre utilise. La broche 3- etant solidaire de 1'embase 1- ne peut egalement tourner. Tout mouvement de rotation imprime au levier 8 entrainera - donc 1e vissage ou 1e devissage de la seconde embase sur 1'extremite filetee de la broche 3 et provoquera 1e serrage ou 1'ecartement des Tondelle et cuvette d'appiii 5 et 19 par rap- port aux pattes 6 et 10. Laxe du moyeu por- tant les cönes 11 et 12 et les rondelles 13 et 14 (striees pour augmenter 1'adherence), se trouve donc fortement serre, mais saus eilet sur 1e reglage des cönes et les roidements proprement dits du moyeu. t1 an end of the pin is blocked Jans a base 4 dopt it thus becomes integral after mounting. This base carries a support plate 5 applied to the leg 6 of the "frame. At the other end, the spindle 3 presents a threaded part 7 which cooperates with a nut forming a second base and carrying a lever B. A support trough 19 rotates freely in a Borge of the second base so as to soften the clamping force.The base 4 is provided with a lug 9 engaged in a groove presented at the end of the In this way, the base 4 can be moved axially, but is fixed in rotation relative to the fax 2. It goes without saying that any other type of lug or known method for preventing the rotation of the base 4 with respect to the lug 6 can be used. The pin 3- being integral with the base 1- cannot also rotate. Any rotational movement imparted to the lever 8 will cause - therefore the first screwing or unscrewing of the second base on the threaded extremity of pin 3 and will cause the clamping or the separation of the cup and the support cup 5 and 19 with respect to the lugs 6 and 10. The axis of the hub carrying the cones 11 and 12 and the washers 13 and 14 (striated to increase grip), is therefore very tight, but without affecting the first adjustment of the cones and the actual stiffness of the hub.

Dans la realisation suiv ant la fig. 2, 1'ac- tion du dispositif de serrage est RTI ID="0001.0270" WI="11" HE="4" LX="1539" LY="1912"> rendue plus rapide par un systeme d'appui ä rampe entre 1.e levier 8 et la cuvette 16. La broche 3 prä sente ä 1'extremite une tete formant arret, tandis que 1e levier 8 presente une rampe simple ou multiple prenant appui sur une rampe complementaire presentee par la cu- vette 16. La cuvette 16 peut se deplacer a,xialement mais non rotativement, par rap- port ä faxe 2, un ergot 9 solidaire de la ci1- rette 16 etant engage dans une rainure de faxe 2. In the embodiment according to FIG. 2, the action of the clamping device is RTI ID="0001.0270" WI="11" HE="4" LX="1539" LY="1912"> made faster by a ramp support system between the lever 8 and the cup 16. The pin 3 presents at the end a head forming a stop, while the first lever 8 has a single or multiple ramp resting on a complementary ramp presented by the cup 16. The cup 16 can move a, xially but not rotationally, relative to the fax 2, a lug 9 integral with the ci1-rette 16 being engaged in a groove of the fax 2.

Pour pouvoir remonter plus facilement la roue lorsque 1'krou 8 est desserre, de petits ressorts tels que 17 sont disposes pour main- tenir les embases ecartees du moyeu et per- mettre d'engager plus facilement les pattes 6 et 10. In order to be able to reassemble the wheel more easily when the lock 8 is loosened, small springs such as 17 are arranged to hold the bases apart from the hub and allow the tabs 6 and 10 to be engaged more easily.

Le dispositif permet d'utiliser une broche de diamUre reduit compatible avec les normes des moyeux de cycles par exemple, tont en permettant d'exercer 1e serrage avee les diamUres de filetalte aussi Brands qu'il est necessaire. Il est facile de transformer les moyeux existants en rempla@ant laxe ordinaire par in axe er eux de longueur convenable, traverse par 1e dispositif de serrage dkrit. The device makes it possible to use a pin of reduced diamUre compatible with the standards of cycle hubs, for example, while allowing the first tightening to be carried out with the diamUres of threadalte as Brands as necessary. It is easy to transform existing hubs by replacing the ordinary axle with an axle of suitable length, crossed by the clamping device described.

L'ecrou 8 pourrait etre un ecrou ä oreilles. Nut 8 could be a wing nut.
