Description
Schnelleinspannvorrichtung, beispielsweise für Fahrradräder- Gegenstand vorliegender Erfindung ist eine Schnelleinspannvorrichtung, beispiels weise für Fahrradräder. In der Zeichnung ist eine beispielsweise Ausführungsform der selben dargestellt. Es zeigt: Fig. <B>1</B> die Sehnelleinspannvorriehtung in entlastetem, Fig. 2 dieselbe in belastetem Zustande.
Gemäss Fig. <B>1</B> bedeuten:<B>1</B> die Radachse; 2 das Radausfallende eines Fahrradrahmens; <B>3</B> eine auf der Radaelise aufschraubbare Ge windehülse mit Flanseli; 4 eine auf dieser axial verseliiebbare, aber gegen Drehung gesi cherte Gleithülse mit einer Sehraubenfläche auf der einen Stirnseite;<B>5</B> eine zwischen<B>3</B> und 4 eingelegte Druckfeder;<B>6</B> den Betäti gungsgriff mit einer Gegenschraubenfliiehe zum Zusammenarbeiten mit der Hülse 4;<B>7</B> ist ein Abdeekreifen; <B>8</B> eine Nasenseheibe;
<B>9</B> eine auf die Hülse<B>3</B> aufsehraubbare Sechskant- mutter, welche die vorgenannten Teile zu sammenhält;<B>10</B> eine die Lage der voreinge- stellten Hülse<B>3</B> sichernde Stellsehraube.
Die Wirkungsweise ist folgende- Nachdem die Schnelleinspannvorriehtung als Ganzes mittels der Hülse<B>3</B> so weit auf die mit einem Gewinde versehene Radaellso aufgesehraubt ist, dass zwischen der entlasteten Gleithülse 4 und dem Radausfallende 2 ein Luftspalt ver bleibt, der "gross genug ist, um das (nicht ge zeichnete) Rad leicht herausnehmen zu kön nen, wird diese gewählte Voreinstellung der Einspannvorrichtung durch Blockieren der Stellschraube<B>10</B> auf der Radachse<B>1</B> fixiert.
Wird hierauf der BetätigUngsgriff <B>6,</B> samt Abdeekreifen <B>7,</B> um die aleithülse <B>3</B> Cgedreht, so bewirkt das Aufgleiten der Schrauben fläche der Druckhülse, die mit dem Griff<B>6</B> ein einziges Stück bildet, auf die Schrauben- flä:ehe der Gleithülse 4 ein Vortreiben der letzteren in axialer Richtung gegen das Aus fallende 2, wodurch, bei genügendem Dreh winkel, ein rasches und sicheres Einspannen des Ausfallendes 2 an der Radaehse <B>1-</B> zu stande kommt (Fig. 2).
Gleich wie durch kur zes Vorwärtsdrehen des Betätigungsgriffes #, <B>C</B> die Schnelleinspannung bewirkt wird, erfolgt durch kurzes Rüekwärtsdrehen desselben ein rasches Lösen der Eimspann-ung, indem unter <B>kn</B> der Einwirkung der Feder<B>5</B> die (-z'Ieithülse 4 sofort in ihre Ausgangsstellung zurilekweieht. <B>z3</B> Da ferner für die dauernde Zentrierun-.- des Rades im Rahmen geeignete Anschläge vor gesehen sind, kann auf die beschriebene Weise ein Wechsel des Rades innert kür zester Zeit bewerkstelligt werden,
-was beson- der-. von Rennfahrern (resehätzt wird.
Zum Überdecken der beim Aufeinander- gleiten der Sehraubenfliiehen 4." und<B>6'</B> (Fig. 2) der Teile 4 und<B>6</B> entstehenden Sehlitzöffnung <B>11</B> ist ein vom Griff<B>6 je-</B> weils durch AnsehIHge <B>71</B> mitgenommener Abdeckreifen <B>7</B> vorgesehen, welcher allen Nachteilen begegnet, die der Sehlit7öffnung .11. zugeschrieben werden könnten.
Um einem ungewollten Lösen der die Voreinstellung sichernden Stellsehraube <B>10,</B> beim Rüekwiirtsdrehen des Griffes<B>6,</B> vorzu- beugen, kann erstere mit Linksgewinde ver sehen sein.
Quick clamping device, for example for bicycle wheels- the subject of the present invention is a quick clamping device, for example for bicycle wheels. An example embodiment of the same is shown in the drawing. It shows: FIG. 1 the tendon clamping device in the unloaded state, FIG. 2 the same in the loaded state.
According to Fig. 1: <B> 1 </B> mean the wheel axle; 2 the dropout end of a bicycle frame; <B> 3 </B> a threaded sleeve with flanseli that can be screwed onto the Radaelise; 4 a sliding sleeve that can be axially displaced on this but is secured against rotation and has a visible surface on one end face; <B> 5 </B> a compression spring inserted between <B> 3 </B> and 4; <B> 6 </ B> the actuating handle with a counter-screw line for working with the sleeve 4; <B> 7 </B> is a dipping tire; <B> 8 </B> a nasal disc;
<B> 9 </B> a hexagon nut which can be screwed onto the sleeve <B> 3 </B> and which holds the aforementioned parts together; <B> 10 </B> a position of the preset sleeve <B > 3 </B> locking adjusting cap.
The mode of operation is as follows - After the Schnelleinspannvorriehtung as a whole by means of the sleeve <B> 3 </B> has been screwed so far onto the threaded wheel that there remains an air gap between the relieved sliding sleeve 4 and the wheel dropout end 2, the " is large enough to be able to easily remove the wheel (not shown), this selected presetting of the clamping device is fixed by blocking the adjusting screw <B> 10 </B> on the wheel axle <B> 1 </B>.
If the actuating handle <B> 6, </B> together with the detachment strip <B> 7, </B> is then rotated around the guide sleeve <B> 3 </B> C, the screw surface of the pressure sleeve, which is connected to the Handle <B> 6 </B> forms a single piece on the screw surface: before the sliding sleeve 4 drives the latter in the axial direction against the falling out 2, whereby, with a sufficient angle of rotation, a quick and safe clamping of the Dropout 2 on the wheel axle <B> 1- </B> comes into being (Fig. 2).
Just like by briefly turning the actuating handle #, <B> C </B> forwards, the quick clamping is effected, by briefly turning it backwards, the clamping mechanism is released quickly by the action of the spring under <B> kn </B> <B> 5 </B> the (-z'Ieithülse 4 immediately moves back into its starting position. <B> z3 </B> Furthermore, since suitable stops are provided for the permanent centering of the wheel in the frame, on the wheel can be changed in a very short time in the manner described
-what special-. by racing drivers (is estimated.
In order to cover the seat seat opening <B> 11 </B> that is created when the very gleaming 4. "and <B> 6 '</B> (FIG. 2) of parts 4 and <B> 6 </B> slide over one another a cover hoop <B> 7 </B> is provided which is carried along by the handle <B> 6 </B> because it is carried along by the cover <B> 71 </B>, which counteracts all the disadvantages that could be ascribed to the window opening .11 .
In order to prevent unintentional loosening of the adjusting screw <B> 10, </B> securing the presetting when turning the handle <B> 6, </B> backwards, the former can be provided with a left-hand thread.
