Description

  

  Gleithülse mit Stellschraube.    Bei den Gleithülsen mit Stellsehraube,wie  sie zum Beispiel bei Ständern aller Art Ver  wendung finden, um einen auf dem Ständer  angeordneten Tragteil in der gewünschten  Höhenlage zu sichern, kommt es häufig vor,  dass die Stellschraube verlorengeht, weil sie  im gelösten Zustand leicht aus dem Gewinde  loch in der Gleithülse herausfallen kann.  



       Durch    die     Erfindung    soll nun dieser nach  teilige Umstand beseitigt werden, und zwar  dadurch, dass ein den Teil der     Gleithülse,    der  die Wandung der Gewindebohrung für die  Stellschraube bildet, durchsetzendes     Siehe-          rungsglied    in eine Umfangsnut des Gewinde  schaftes der letzteren eingreift und dadurch  das     Herausschrauben    der Stellschraube ver  hindert, wobei diese Umfangsnut so breit ist,  dass dieses Sicherungsglied weder das Anzie  hen noch das Lösen der Stellschraube     behin-          d    ert .  



  Auf der beiliegenden Zeichnung ist in  einer     einzigen    Figur ein Ausführungsbeispiel  des Erfindungsgegenstandes veranschaulicht.  



  a ist die Säulenstange eines zum Beispiel  für Fensterauslagen bestimmten Ständers,  und b ist eine auf dieser Stange angeordnete,  im Schnitt gezeichnete Gleithülse, die bei  spielsweise dazu dienen kann, einen ebenfalls  auf dieser Stange verschiebbar angeordneten,  hier nielt gezeigten Tragteil in der gewünsch  ten Höhenlage auf dem Ständer zu sichern.  Diese     Gleithülse    b ist an ihrem obern Ende  mit einer quer verlaufenden Gewindebohrung    versehen, in der eine Stellschraube c vorgese  hen ist.

   Im Gewindeschaft dieser Stellschraube  ist eine verhältnismässig breite Umfangsnut     cl     vorgesehen, in die ein     Sicherungsglied    ein  greift, das das vollständige Herausschrauben  der Stellschraube c aus der Gleithülse     ver-          unmöglicht.    Dieses Sicherungsglied besteht  aus einer geschlitzten Federhülse d, die sich  in paralleler Richtung zur Stange a durch  den die Wandung der Gewindebohrung in der       Gleithülse    bildenden Teil. dieser letzteren hin  durch erstreckt. Begreiflicherweise könnte  sieh diese Feder zum Beispiel auch in einer  zur Stange a quer verlaufenden Richtung in  die Umfangsnut cl hinein erstrecken.

   Diese  Umfangsnut     cl        ist.    in jedem Fall so breit, dass  die Federhülse d weder das Anziehen noch  das Lösen der Stellschraube behindert.



  Sliding sleeve with adjusting screw. In the case of the sliding sleeves with adjusting screw, as they are used, for example, in all kinds of stands, to secure a support part arranged on the stand at the desired height, it often happens that the adjusting screw is lost because it is easy to get out of the released state Thread hole in the sliding sleeve can fall out.



       This disadvantageous circumstance is now to be eliminated by the invention, namely in that a reference member penetrating the part of the sliding sleeve that forms the wall of the threaded hole for the adjusting screw engages in a circumferential groove of the threaded shaft of the latter and thereby unscrewing prevents the adjusting screw, this circumferential groove being so wide that this securing member neither hampers the tightening nor the loosening of the adjusting screw.



  In the accompanying drawing, an embodiment of the subject matter of the invention is illustrated in a single figure.



  a is the column rod of a stand, for example for window displays, and b is a sliding sleeve arranged on this rod, drawn in section, which can be used, for example, to support a supporting part also slidably arranged on this rod, shown here in the desired height secure on the stand. This sliding sleeve b is provided at its upper end with a transverse threaded hole in which an adjusting screw c is vorgese hen.

   A relatively wide circumferential groove cl is provided in the threaded shaft of this adjusting screw, into which a locking member engages, which makes it impossible to completely unscrew the adjusting screw c from the sliding sleeve. This securing member consists of a slotted spring sleeve d, which extends in a direction parallel to the rod a through the part forming the wall of the threaded hole in the sliding sleeve. this latter extends through. Understandably, this spring could, for example, also extend into the circumferential groove cl in a direction running transversely to the rod a.

   This circumferential groove cl is. in any case so wide that the spring sleeve d does not prevent the tightening or loosening of the adjusting screw.
