  Vorrichtung zum einstellbaren Feststellen von Verlängerungsstücken an   Leiterholmen,   Rüstbock- füssen, Stangen u. dgl. 



   Für Leitern, insbesondere Gartenleitern, Rüstböcke u. dgl., welche auf unebener Unterlage aufgestellt werden, besteht das Bedürfnis, die Leiterholme, Boekfüsse u. dgl., u. zw. jeden Holm u. dgl. um ein anderes durch die Unebenheit gegebenes Mass verlängern zu können. Die   Verlängerungsstücke   müssen daher an den zu verlängernden Teil an beliebiger Stelle feststellbar sein. 



   Die bekannten Feststellvorrichtungen sind meist mit der Leiter u. dgl. fest verbunden (ausziehbare Leitern) und bestehen aus Sperrklinken, Steckbolzen u. dgl. 



   Gegenstand der Erfindung bildet die Art der Feststellung der keinen Teil der Leiter od. dgl. bilden- 
 EMI1.1 
   schrägt,   dass sie mit der ihr zugekehrten Holmfläche einen keilförmigen Hohlraum bildet. In diesen wird nach Einstellung der gewünschten Verlängerung eine Walze W   gedrückt,   welche eine gegenseitige Verschiebung von Holm und   Verlängerungsstück in   der angedeuteten Pfeilrichtung verhindert. 



   Der erforderliche keilförmige Hohlraum kann auch statt durch Abschrägung dadurch erzielt werden, dass Holm und   Verlängerungsstück   selbst einen spitzen Winkel miteinander bilden (Fig. 3 und 4). 



   Auch Rundhölzer, wie Stangen   R   (Fig. 5 und 6), können mit Zuhilfenahme dieser Erfindung beliebig verlängert werden, wenn sie mindestens einseitig mit einer   Fläche   versehen sind, gegen welche die   abgeschrägte Fläche   des Verlängerungsstücks mittels entsprechend geformter Schellen   S   od. dgl. angedrückt wird.

  Device for adjustable fixing of extension pieces on ladder rails, trestle feet, rods and the like. like



   For ladders, especially garden ladders, trestles and the like. Like. Which are set up on an uneven surface, there is a need, the ladder bars, Boekfüsse u. like., u. between each spar u. Like. To be able to extend another dimension given by the unevenness. The extension pieces must therefore be lockable at any point on the part to be extended.



   The known locking devices are usually u with the ladder. Like. Firmly connected (extendable ladders) and consist of pawls, socket pins and. like



   The subject of the invention is the type of determination of no part of the ladder or the like.
 EMI1.1
   inclined so that it forms a wedge-shaped cavity with the spar surface facing it. In this, after setting the desired extension, a roller W is pressed, which prevents a mutual displacement of the spar and extension piece in the direction of the arrow.



   The required wedge-shaped cavity can also be achieved, instead of by beveling, that the spar and extension piece themselves form an acute angle with one another (FIGS. 3 and 4).



   Round timber, such as rods R (Fig. 5 and 6), can be extended as required with the aid of this invention if they are provided at least on one side with a surface against which the beveled surface of the extension piece is pressed by means of appropriately shaped clamps S or the like becomes.
