Abstract

Device for fixing a sprung head stem of handle-bars into the bicycle fork is formed in such a way that the fixing tube (1) possesses on its surface longitudinal slots (3) and is wedge-like ended at the bottom. Into the slots (3) are fitting the pull rods (2) reaching with their tips, provided by a thread, into a cap nut (7), resting on a supporting ring (8). The expanding wedge (5) is placed on the carrier (4) which is permanently connected with the pull rods (2).

Description

Zariadenie na upevnenie odpruženého pted&tavca kormidla do vidlice bicyklaA device for attaching a sprung & melted rudder to the fork of a bicycle

Oblasť., technikyTechnique

Vynález sa týka zariadenia na upevnenie odpruženého predstavca kormidla do vidlice bicyklaBACKGROUND OF THE INVENTION The present invention relates to a device for attaching a sprung rudder stem to a bicycle fork

Doterajší stav technikyBACKGROUND OF THE INVENTION

Doteraz známe upevnenie predstavca kormidla do vidlice bicykla vychádza z podstaty US patentu č. 4 130 260, ktorá spočíva v tom, že do dutého stĺpika prednej vidlice je zasunutý dutý stĺpik predstavca alebo kormidla, ktorý má na spodnej časti dve pozdĺžne drážky a vnútorné kuželové zrezanie. Do neho sa skrutkou vťahuje rozpinací kužeí, ktorý pritláča spodnú časť stĺpika predstavca alebo kormidlo na vnútornú valcovú plochu stĺpika prednej vidlice. Vzniknutým trením je zaistené spojenie obidvoch častí. Podobný spôsob upevnenia, známy z opisu vynálezu k CS 226 400, spočíva v tom, že medzi volný koniec stĺpika kormidla resp. predstavca, ktorý je vytvarovaný ako komolý kužel, a volný koniec stĺpika prednej vidlice je skrutkou dotiahnutá matica valcovitého tvaru s vnútornou kuželovou plochou s aspoň jedným pozdĺžnym zárezom. Nevýhodou obidvoch upevnení je to, že nedovoľujú lineárny pohyb predstavca voči vidlici bicykla. Stredová skrutka taktiež neumožňuje využitie vnútorného priestoru rúrky na odpruženie predstavca kormidla.The hitherto known attachment of the rudder stem to the fork of the bicycle is based on the nature of U.S. Pat. No. 4,130,260, characterized in that a hollow pillar of the stem or rudder, which has two longitudinal grooves and an inner conical trimming, is inserted into the hollow pillar of the front fork. An expansion cone is screwed into it, which presses the lower part of the stem or rudder against the inner cylindrical surface of the front fork column. The resulting friction ensures the connection of both parts. A similar method of attachment known from the description of the invention to CS 226 400 is that between the free end of the rudder pillar and the helm pillar. the stem, which is shaped as a truncated cone and the free end of the front fork column is a bolt-tightened cylindrical nut with an inner conical surface with at least one longitudinal slot. The disadvantage of both fasteners is that they do not allow linear movement of the stem relative to the fork of the bicycle. Also, the central screw does not allow the use of the inner space of the tube to cushion the rudder stem.

Podstata vynálezuSUMMARY OF THE INVENTION

Vyššie uvedené nedostatky odstraňuje zariadenie na upevnenie odpruženého predstavca kormidla do vidlice bicykla, ktorého podstata spočíva v tom, že upevňovacia rúrka je na spodnom konci vybavená klinovým zakončením a na povrchu má vytvorené dve drážky, do ktorých zapadajú ťahadlá, ktoré majú v hornej časti závit. Ten zasahuje do prevlečenej matice, ktorá je na opornom krúžku. Ťahadlá sú spojené s nosičom rozperného klinu a na ňom je rozperný klin. Výhodou tohoto zaria7 denia je to, že umožňuje odpruženie predstavca kormidla s využitím vnútorného priestoru upevňovacej rúrky.The aforementioned drawbacks are eliminated by a device for attaching the sprung stem to the fork of the bicycle, the principle being that the fastening tube is provided with a wedge end at its lower end and has two grooves on the surface in which the threaded rods engage. It extends into the union nut, which is on the support ring. The linkage is connected to the spreader carrier and has a spacing wedge. The advantage of this device is that it allows suspension of the rudder stem using the inner space of the fixing tube.

Zariadenie podľa vynálezu je realizované napr. tak, že upevňovacia zakončením _ vyfrézované drážky, rúrka 1 je na spodnom konci vybavená klinovým 6. Na povrchu upevňovacej rúrky sú súmerne do ktorých zapadajú ťahadlá 2, v hornej časti so závitom. V spodnej časti ťahadlá 2 prechádzajú do celistvej rúrky, v ktorej je prostredníctvom priečnych kolíkov upevnený nosič 4 rozperného klinu, na ktorom spočíva rozperný klin 5> V hornej časti upevňovacej rúrkyThe device according to the invention is realized e.g. so that the grooved end of the grooved end of the pipe 1 is provided with a wedge 6 at its lower end. On the surface of the pipe there are symmetrically in which the rods 2 fit in the upper part of the thread. In the lower part of the rods 2 they pass into an integral tube, in which a spacer wedge carrier 4 is fastened by means of cross pins, on which the spacer wedge rests 5> In the upper part of the fixing tube
