PATENTAMT.PATENT OFFICE.
Bei Teleskoprohrmasten müssen die nacheinander herausgezogenen Rohrteile in ihrer Auszugsstellung verriegelt und beim Zusammenschieben des Mastes wieder entriegelt werden. Nach der Erfindung geschieht dies dadurch, daß am oberen Ende der einzelnen Rohre in Bügeln federnd gelagerte Sperrbolzen angeordnet sind, welche die nächstinneren Rohre in ihrer Auszugsstellung verriegeln, währendIn the case of telescopic tube masts, the tube parts that are pulled out one after the other must be in their Locked in the extended position and unlocked again when the mast is pushed together. According to the invention, this is done in that at the top of the individual tubes in Bracket spring-loaded locking pins are arranged, which the next inner tubes lock in their extended position while
ίο sie beim Einziehen des Mastes durch keilförmige, sich unter Anschläge der Sperrbolzen einschiebende Gabeln aus der Sperrstellung zurückgezogen werden.ίο when retracting the mast, they use wedge-shaped, Forks pushing in under stops of the locking bolts are withdrawn from the locking position.
In der Zeichnung ist ein senkrechter Schnitt durch einen Teleskoprohrmast in eingezogener Lage dargestellt. 1, 2 und 3 sind die einzelnen Rohre des Teleskopmastes. Die inneren Rohrstücke sind mit einer Reihe von Öffnungen 4 versehen, die in gleichem Abstande voneinander stehen, entsprechend der Teilung eines zum Auftrieb und zum Einziehen des Mastes bestimmten Zahnrades 9. Die oberen Enden der Rohre sind in an sich bekannter Weise mit Anschlägen 5, die unteren Enden dagegen mit Anschlägen 6 versehen, durch welche ein vollständiges Herausziehen der Rohre verhindert und die Verschiebbarkeit der Mastteile untereinander begrenzt wird.The drawing shows a vertical section through a telescopic tubular mast in retracted Location shown. 1, 2 and 3 are the individual tubes of the telescopic mast. The inner ones Pipe sections are provided with a number of openings 4, which are equidistant from one another stand, according to the division of a for buoyancy and for pulling in the Mastes specific gear 9. The upper ends of the tubes are known per se Way with stops 5, the lower ends, however, provided with stops 6 by which prevents the pipes from being pulled out completely and the ability to move the mast parts are limited to each other.
Die Auftriebsvorrichtung besteht in an sich bekannter Weise aus einem am Zapfen 7 drehbar gelagerten Hebel 8, der am oberen Ende das Zahnrad 9 trägt, das durch eine auf den Hebel 8 wirkende Feder 11 mit seinen Zähnen 10 gegen die Rohrteile und in die Öffnungen 4 eingedrückt wird.The buoyancy device consists, in a manner known per se, of a rotatable on the pin 7 mounted lever 8, which carries the gear 9 at the upper end, which by a on the The spring 11 acting on the lever 8 with its teeth 10 against the pipe parts and into the openings 4 is depressed.
Die Ver- und Entriegelungsvorrichtung besteht aus in Bügeln 12 gelagerten Sperrbolzen 13, die unter Wirkung von Federn 14 stehen. Diese Sperrbolzen sind am oberen Ende eines jeden Rohres angeordnet und greifen nach dem Herausziehen des nächstinneren Rohres selbsttätig unter dessen unteres Ende. Zur Entriegelung sind keilförmig gestaltete Gabeln 16 vorgesehen, die ebenfalls am oberen Ende der einzelnen Rohre angeordnet und so bemessen sind, daß sie beim Einziehen des Mastes unter Anschläge 17 greifen, welche auf den Sperrbolzen 13 des nächstinneren Rohres angeordnet sind. Hierdurch wird der Bolzen aus seiner Sperrlage zurückgezogen und das Rohr freigegeben.The locking and unlocking device consists of locking bolts mounted in brackets 12 13, which are under the action of springs 14. These locking pins are arranged at the upper end of each tube and follow suit pulling out the next inner tube automatically under its lower end. To the Unlocking, wedge-shaped forks 16 are provided, which are also at the upper end of the individual tubes are arranged and dimensioned so that they grip when retracting the mast under stops 17, which on the locking pin 13 of the next inner tube are arranged. This will make the bolt withdrawn from its locked position and released the tube.
