Definitions

  • the present invention is conected to devices for the assembly and the secure subordination of mechanical committees as a rule, and but particularly is referring to a nut car-adjustable subordination having by purpose offered a middle link you extremely secure, rapid and effective, that favors the mechanics connection by threaded in optimum conditions.
  • PATENT N 72.444 a) Include a nut provided in its inferior face of two steps. b) The nut is screwed in the extreme ofthe shaft ofthe session, fixon this through a prisoner screw. This characteristic is outspokenly negative for the efficiency ofthe invention since
  • the nut does not require from fixing of prisoner, forelock or additional element some, 35 since is hobble by the simple action of the extremes in the form of levy and remains thus car -held until much is turned to loosen when is withdrawn said levy by refutation of the lever.
  • the command arm permits threaded and unscrew to will in direct way on the same, and to define each position adopted through the fold of such arm in the form of levy trammelling.
  • d) has not such step but possesses a mean cane in two sections disposed in wheel to the nut, what makes from hobble of the same.
  • e) Does not require from spike neither no another piece to produce the perfect hobble, rapid and axe.
  • Incluse it has several advantages: to draw the lever, since this is found articulated to the own nut, is extracted simultaneously all the set of nut, lever and socket-pan (in the case ofthe patent to extract one is disarmed all the set since this is from loose pieces), h) The extremes ofthe lever are from section oval, so that to rotate, by diameters difference work as eccentric levies and join with the fold over and aver of the own lever against the session, i) By jam, is repit, only the work for eccentricity. Not dowel, no perforations. j) The productive costs and the operations are sensibly smaller, and of all this results also a greater safety.
  • the new nut object of the invention permits the easy thrreaded and unscrew with driving direct in its own constitution and, fundamentally, the car particularity -be adjusted so soon is fold its lever enabling the greater diameter sector of the rod that composes it, the one which to levy manner, after to reach the threaded maximum maintains holds the nut with the ledger, and without possibility of slokening some; while, when it is wished to unscrew said nut, enough to lift the lever to produce the slokening and to permit the rapid rotation in the direction of such unscrew.
  • the figure 1 is a partial court of the nut devices car
  • FIG 3 is a lateral sight of the nut device already tight and with the fold over and over lever so that acting the highest part ofthe terminals in levy, produces the retentive adjustment with maximum pressure.
  • the figure 4 a detail in court the lever indicating the manner in which is made it to work as rotary command of threaded and unscrew of the referring nut.
  • the figure 5, a diagrammatical diametrical court of a bicycle session mounted to its shaft through a nuts game as the one which is object ofthe present invention, observing is an of these already tight nuts, with the same on whether folded over and over lever, while the other is shown before to be tightened; and finally.
  • the figure 6, a detail in frontal sight of the same session of the example of application of the figure 5, with the tight nut and the solded over and over lever joined with safety.
  • the Turk (to) of car subordination -adjustable of reference it is ofthe type that understand a tubular body (2) threaded (4) the one which, articulated by a part with a lever (b) of rotary command, additionally it has mounted a socket-pan (c), characterized because, the body (1) ofthe nut (a) is extended with a neck (2) that, giving assembly in hostile way to the socket-pan (c), ends in an extreme with a curbing -ceiling (3) in quality withholding middle of the same on its own bearing; this socket-pan c -in relationship to the joint area (5) ofthe command lever (b) -delimits a space (9) of variable magnitude in the one which are intercalated the extremes (11 ) of such lever (b) those which, at least in those extremes (11) and to levy manner,
  • the nut (to) of reference understands a principal body (1 ) conformative of a tubular head, affected under an interior coil (4) that monopolizes all the extension of the drilling, and provided of a command lever (b) that, articulated with that, make possible s its driving rotary for the operations of threaded or unscrew, respectively.

Abstract

Ecrou à déverrouillage rapide constitué d'un corps fileté tubulaire (a) sur lequel sont fixés un manchon (c) et un levier de commande (b), pouvant être utilisé pour une roue de bicyclette (v), caractérisé par le fait que le corps (a) de l'écrou présente une collerette saillante (2) autour de laquelle le manchon (c) est retenu de façon lâche, ce qui fait qu'il peut se déplacer axialement le long de la collerette (2). Le corps est muni d'un rebord (3) empêchant la sortie du manchon (c), et le levier (b) est muni d'une surface de came (11) agissant entre le manchon (c) et le corps (a) de façon à déplacer l'un par rapport à l'autre.
