Description

Die Erfindung betrifft verstellbare Metallstützen mit zwei teleskopartig ineinander verschiebbaren Teilen, die dadurch ungefähr in die richtige Lage eingestellt werden können, daß man den inneren Teil mit Hilfe eines durch Schlitze im äußeren Teil gehenden Stiftes und mit Hilfe von Löchern im inneren Teil gegenüber dem äußeren Teil festlegt, wobei die endgültige Einstellung durch eine Mutter erreicht wird, die ein mit Gewinde versehenes Stück des äußeren Teiles erfaßt und sich gegen die vorstehenden Enden des Stiftes legt.The invention relates to adjustable metal supports with two telescopic mutually displaceable parts, which are thereby set approximately in the correct position can be that you can get the inner part with the help of a through slots in the outer Part of the going pin and with the help of holes in the inner part opposite the outer Part, with the final setting being achieved by a nut, which engages a threaded piece of the outer part and is against the protruding ends of the pin sets.

ach der Erfindung werden bekannte Durchbildungen von Stützen dieser Art verbessert. Die Erfindung besteht darin, daß die Mutter mit einer daran hängenden Hülse versehen ist, welche den unterhalb der Mutter liegenden Gewindeteil bedeckt, während eine zweite Hülse auf der Mutter aufliegt, um den oberhalb der Mutter liegenden Gewindeteil zu schützen, und den Stellstift trägt, der durch Löcher oder Schlitze im unteren Teil der zweiten Hülse gesteckt werden kann.after the invention are known implementations of supports of these Kind of improved. The invention is that the mother with a hanging on it Sleeve is provided which covers the threaded part lying below the nut, while a second sleeve rests on the nut, around the one above the nut To protect threaded part, and the adjusting pin carries through holes or slots can be inserted in the lower part of the second sleeve.

Weitere Merkmale der Erfindung sind aus der folgenden Beschreibung ersichtlich.Further features of the invention are apparent from the following description evident.

Auf der Zeichnung ist eine Ausführungsform einer Stütze nach der Erfindung beispielsweise dargestellt.In the drawing is an embodiment of a support according to the invention for example shown.

Fig. i ist eine Vorderansicht; Fig. 2 ist eine Seitenansicht; Fig.3 zeigt in größerem Maßstab im Schnitt einen Teil der Stütze der Fig. i und 2; Fig. 4 zeigt eine Einzelheit in Ansicht.Fig. I is a front view; Fig. 2 is a side view; Fig. 3 shows, on a larger scale, in section part of the support of FIGS. 1 and 2; Fig. 4 shows a detail in view.

Die Stütze nach der Erfindung besteht aus zwei teleskopartig ineinander verschiebbaren, rohrförmigen Teilen, dem äußeren Rohr a, das mit einem Fuße und mit Außengewinde a2 auf einem Teil seiner Länge versehen ist, auf dem eine Mutter b mit einem Handgriff c gedreht werden kann. Der innere Teil d, der im äußeren Rohr a verschiebbar ist, kann je nach dem Verwendungszweck der Stütze verschiedene Formen haben. Das Innenrohr d ist mit Löchern dl versehen, die über dessen Liirige verteilt einander gegenüberliegen, so daß man dieses innere Rohr ungefähr in der richtigen Lage mit Hilfe eines Stiftes e einstellen kann, der durch Löcher dl und durch Schlitze a3 gesteckt werden kann, die im Gewindeteil des Außenrohrs einander gegenüberliegend vorgesehen sind. Die endgültige Einstellung wird durch Drehen der Mutter b erzielt, welche sich gegen die herausragenden Enden des Stiftes e legt.The support according to the invention consists of two telescoping tubular parts, the outer tube a, which is provided with a foot and with an external thread a2 over part of its length, on which a nut b can be turned with a handle c. The inner part d, which is slidable in the outer tube a, can have different shapes depending on the intended use of the support. The inner tube d is provided with holes dl, which are distributed across its Liirige opposite each other, so that you can adjust this inner tube approximately in the correct position with the help of a pin e, which can be inserted through holes dl and through slots a3 in the Threaded part of the outer tube are provided opposite one another. The final adjustment is achieved by turning the nut b, which rests against the protruding ends of the pin e.

Die Mutter hat eine ungelochte Hülse f, die entweder mit ihr aus einem Stück besteht oder mit ihr verbunden ist und die so lang ist, daß für alle Stellungen der Mutter der unterhalb der Mutter liegende Gewindeteil des Außenrohres verdeckt und geschützt liegt. Der Stifte ist durch eine Kette oder einen Lenker la auf einer Hülse g befestigt, die so lang ist, daß sie stets den oberhalb der Mutter liegenden Gewindeteil des Außenrohres wirksam verdeckt und schützt. Die Hülse g hat zwei offene Schlitze g1 (Fig. 4) oder zwei an ihrem unteren Ende einander gegenüberliegende Löcher, so daß der Stift e durch beide teleskopartig ineinander verschiebbare Teile gesteckt werden kann. Die untere Hülse f dreht sich mit der -Mutter, während die obere Hülse g auf ihr aufliegt. Der Gewindeteil a2 des Außenrohres wird daher vollständig während der ganzen Einstellung der Stütze geschützt, wodurch die erwähnten Vorteile erreicht werden.The nut has an unperforated sleeve f, which either with it from a Piece consists or is connected to it and which is so long that for all positions the nut covers the threaded part of the outer tube located below the nut and lies protected. The pin is by a chain or a handlebar on a la Sleeve g attached, which is so long that it always lies above the mother Effectively covers and protects the threaded part of the outer tube. The sleeve g has two open ones Slots g1 (FIG. 4) or two opposite one another at their lower end Holes, so that the pin e through both telescoping parts can be plugged. The lower sleeve f rotates with the nut, while the upper sleeve g rests on it. The threaded part a2 of the outer tube therefore becomes complete Protected throughout the adjustment of the support, thus giving the advantages mentioned can be achieved.
