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.
