Description

  

      Speichenschlüssel.       Gegenstand vorliegender Erfindung     iss     ein Speichenschlüssel, dadurch gekennzeichnet,  dass er einen länglichen Körper aufweist, in  dessen Längsrichtung eine Bohrung verläuft,  die an mindestens einem ihrer Enden in einem  Innenvierkant endet und in die ein Längs  schlitz einmündet, und ferner, dass er ein Paar  in Querrichtung zum. genannten Körper ver  schiebbar gelagerte, unter Federdruck     anein-          anderliegende    Kugeln aufweist, die     bezwecken,     bei aufgesetztem Speichenschlüssel dessen  selbsttätiges     Festklemmen    an der Speiche zu  bewerkstelligen, derart, dass er relativ zur  Speiche verdreht werden kann.  



  Beiliegende Zeichnung stellt ein Ausfüh  rungsbeispiel des Erfindungsgegenstandes dar.       Fig.l    ist eine Seitenansicht, teilweise im  Schnitt längs der Linie     1--I    der       Fig.2,    die eine Draufsicht des Ausfüh  rungsbeispiels zeigt.  



  Mit 1 ist ein länglicher Schlüsselkörper be  zeichnet, der eine Längsbohrung 2 aufweist,  anderen Enden Innenvierkante 3 verschiedener  Grösse vorgesehen sind, und einen in die Boh  rung mündenden Längsschlitz 4 aufweist. Auf'  halber Länge des Körpers 1 sind zwei     rohr-          förmige    Griffarme 5 diametral gegenüberlie  gend eingeschraubt, deren Achsen in einer  Ebene liegen, die zur Ebene durch die Längs  achse des Schlüsselkörpers 1 und seinen Schlitz  4 senkrecht steht.

   Zwei in diesen     Gxriffarmen    5  in Querrichtung zum Körper 1     verschiebbar     gelagerte Kugeln 6 werden durch zwei je in    einem dieser Griffarme untergebrachte und  sich auf Gewindezapfen 7 abstützende Schrau  benfedern 8     gegeneinandergedrückt,    so dass  sie     aneinanderliegen.     



  Der beschriebene Speichenschlüssel arbeitet  wie folgt:  Bei der Verschiebung der den zu verdre  henden Nippel tragenden Speiche in radialer  Richtung des Drehkörpers 1, durch den Schlitz       -1,    zwecks     Aufsetzens    des Speichenschlüssels,  drückt die Speiche die Kugeln 6 entgegen der  Kraft der Federn 8 auseinander und geht zwi  schen ihnen hindurch. Nachher, bei der Ver  schiebung des Schlüssels     längs    der Speiche,  beim Aufsetzen des einen Innenvierkantes 3  auf den Nippel und bei dessen Verdrehen mit  tels des Schlüssels, bewerkstelligen die Kugeln  6 unter dem Druck der Federn 8 das selbst  tätige Festklemmen des Speichenschlüssels,  wobei sie aber ein Verdrehen des     Schlüssels     relativ zur Speiche nicht verhindern.

   Ferner  begünstigen die Kugeln durch ihre Form das  leichte Ein- und Ausfahren beim Ansetzen  und Wegnehmen des Speichenschlüssels.



      Spoke wrench. The subject of the present invention iss a spoke wrench, characterized in that it has an elongated body, in the longitudinal direction of which runs a bore which ends at at least one of its ends in an internal square and into which a longitudinal slot opens, and further that it has a pair in Cross direction to. said body has displaceably mounted balls lying against one another under spring pressure, the purpose of which is to achieve its automatic clamping to the spoke when the spoke wrench is in place, so that it can be rotated relative to the spoke.



  The accompanying drawing shows an exemplary embodiment of the subject matter of the invention. Fig.l is a side view, partly in section along the line 1 - I of FIG. 2, which shows a plan view of the exemplary embodiment.



  1 with an elongated key body be characterized, which has a longitudinal bore 2, other ends inner square 3 of different sizes are provided, and a longitudinal slot 4 opening into the Boh tion. Halfway along the length of the body 1, two tubular handle arms 5 are screwed diametrically opposite each other, the axes of which lie in a plane which is perpendicular to the plane through the longitudinal axis of the key body 1 and its slot 4.

   Two in these Gxriffarmen 5 in the transverse direction to the body 1 slidably mounted balls 6 are benfedern 8 pressed against each other by two each housed in one of these handle arms and supported on threaded pin 7 screw so that they rest against each other.



  The spoke wrench described works as follows: During the displacement of the spoke carrying the nipple to be rotated in the radial direction of the rotating body 1, through the slot -1, for the purpose of placing the spoke wrench, the spoke pushes the balls 6 apart against the force of the springs 8 and go between them. Afterwards, when the key is moved along the spoke, when the one inner square 3 is placed on the nipple and when it is turned with means of the key, the balls 6, under the pressure of the springs 8, manage the self-acting clamping of the spoke key, but they do do not prevent the key from turning relative to the spoke.

   The shape of the balls also makes it easy to move in and out when attaching and removing the spoke wrench.
