Description

  

  Stütze für Baumleitern.    Es sind Stützen für     Baumleitern    bekannt,  welche aus zwei scherenartig     aneinander-          gelenkten    Stangen bestehen, an deren Enden  Haken vorgesehen sind. Diese Stangen grei  fen mittelst der Haken an den verhältnis  mässig schwachen Sprossen an.  



  Gegenstand vorliegender Erfindung ist  eine Stütze, welche an den Leiterholmen an  greift.     .Sie    besteht aus zwei     gleichgebauten,     kreuzweise     aufstellbaren    Stangen, von denen  jede an ihrem obern Ende     m:it    einer     offenen,     Mittel zum Umfassen je eines der Holme  aufweisenden Gabel versehen ist. Die     Stütze     kann derart ausgebildet sein, dass jede     Stange     für sich     aufstellbar    ist.  



  Auf der beiliegenden Zeichnung ist eine  beispielsweise Ausführungsform des Erfin  dungsgegenstandes dargestellt. Es zeigen:       Fig.    1 einen Teil einer Leiter mit den  an den Holmen angreifenden Gabeln der  Stütze, im     Aufriss,    und in       Fig.    2 im Grundriss;       Fig.    3 und 4 stellen in     Vorder-        bezw.          Seitenansicht    das Ende einer einzelnen Stange  der Stütze dar.    1 und 2 sind die Holme einer Baumleiter.  Zum Stützen derselben dienen zwei Stangen  4, 5, die oben je eine Gabel 3 aufweisen.  Letztere besitzt zwei Arme 6, 7, welche zu  sammen einen Holmen umfassen können.  



  An den Gabeln 3 ist ein Rohrstück 8 an  geschweisst, in welches die Stange eingesteckt  ist.  



  Während das eine Ende 6 der Gabel die  vordere Seite des Holmes umfasst, erfasst das  andere Ende 7 die hintere Seite und eine  Sprosse. Beim Bruch der Sprosse werden die  Holmen 1, 2 zwischen den Gabelarmen ein  geklemmt, so dass die Leiter ohne Zuhilfe  nahme von Sprossen gehalten wird, und nicht  fallen kann.  



  Die beiden Stangen werden     zweckmässig,     sich kreuzend, unabhängig voneinander auf  dem Boden abgestützt. Da die Holmen von  den Gabeln fast gänzlich umfasst werden, so  ist grosse Sicherheit gegen ein Verstellen oder  ein Brechen der Stützeinrichtung gegeben,  da nicht, wie bei bekannten Leiterstützen,  hauptsächlich die     verhältnismässig    schwachen  Sprossen beansprucht werden.



  Support for tree ladders. There are known supports for tree ladders which consist of two scissor-like rods articulated to one another and at the ends of which hooks are provided. These rods grip the relatively weak rungs by means of the hooks.



  The present invention is a support which engages on the ladder rails. It consists of two identically constructed rods that can be set up crosswise, each of which is provided at its upper end with an open fork, each having a means for embracing one of the bars. The support can be designed in such a way that each pole can be set up on its own.



  In the accompanying drawing, an example embodiment of the subject of the invention is shown. They show: FIG. 1 a part of a ladder with the forks of the support engaging on the stiles, in elevation, and in FIG. 2 in plan; 3 and 4 represent in front or respectively. Side view shows the end of a single pole of the support. Figures 1 and 2 are the stiles of a tree ladder. Two rods 4, 5, each of which has a fork 3 at the top, serve to support the same. The latter has two arms 6, 7, which can include a spar together.



  On the forks 3, a piece of pipe 8 is welded into which the rod is inserted.



  While one end 6 of the fork includes the front side of the spar, the other end 7 includes the rear side and a rung. When the rung breaks, the bars 1, 2 are clamped between the fork arms so that the ladder is held by rungs without assistance and cannot fall.



  The two rods are expediently supported on the floor, crossing each other, independently of one another. Since the spars are almost completely encompassed by the forks, there is great security against adjustment or breaking of the support device, since it is not mainly the relatively weak rungs that are stressed, as is the case with known ladder supports.
