Description

  

      Gerüstbock.       Vorliegende Erfindung betrifft einen  Gerüstbock, der in der Höhe verstellbar ist.    Beiliegende Zeichnung zeigt den Erfin  dungsgegenstand beispielsweise, und zwar  zeigt:       Fig.    1 einen Aufriss des Gerüstbockes,       Fig.    2 eine Draufsicht auf den längs der  Linie     A-A        (Fig:    1) geschnittenen Gerüst  bock,       Fig.    3 eine Seitenansicht der Arretierung,       Fig.    4 eine Draufsicht der Arretierung.  Der Gerüstbock weist einen Dreifuss auf,  dessen drei schräge Füsse 1 am Kopfende  durch zwei Platten "2 und 3 verbunden sind.

    Diese Platten dienen zur Aufnahme der Trag  stange 4, die aus einem     T-förmigen    Stück,  welches mit Sperrzähnen versehen ist, be  steht. An der Platte 3 ist in einem Lager 5  ein Sperrstück 6 drehbar angeordnet, Die  ses Sperrstück 6 besteht aus einer Sperr  klinke 7, die in die Sperrzähne der Trag  stange 4 eingreift, ferner aus den     Auflage-          nocken    8, die beiderseits der     Sperrklinke    7    auf der Platte 3 aufliegen; ausserdem besitzt  das Sperrstück noch einen Handhebel 9.  



  Soll der Gerüstbock tiefer eingestellt  werden, so drückt die eine Hand auf den  Handhebel 9, wodurch sich das Sperrstück 6  im Lager 5 dreht und die     Sperrklinke    7  in die gestrichelt gezeichnete Stellung ausser  halb der Sperrzähne der Tragstange gelangt.  In dieser Stellung kann die Tragstange mit  der andern Hand     tiefer        gestellt    werden.  Lässt die Hand den Hebel 9 los, so fällt  die Sperrklinke 7 durch das Eigengewicht       in    die Sperrzähne der Tragstange ein und  verhindert das     Herabgleiten    derselben. Die       Höherstellung    der Tragstange erfolgt durch  Zug an derselben. Am obern Ende der Trag  stange befindet sich die Auflage 10.



      Scaffolding trestle. The present invention relates to a trestle which is adjustable in height. The accompanying drawing shows the subject of the invention, for example, namely: Fig. 1 is an elevation of the trestle, Fig. 2 is a plan view of the trestle cut along the line AA (Fig: 1), Fig. 3 is a side view of the lock, Fig. Figure 4 is a top view of the lock. The trestle has a tripod, the three inclined feet 1 of which are connected at the head end by two plates 2 and 3.

    These plates are used to accommodate the support rod 4, which is made of a T-shaped piece, which is provided with ratchet teeth, be. On the plate 3, a locking piece 6 is rotatably arranged in a bearing 5. The locking piece 6 consists of a locking pawl 7 which engages in the ratchet teeth of the support rod 4, and also of the support cams 8 on both sides of the pawl 7 the plate 3 rest; The locking piece also has a hand lever 9.



  If the trestle is to be set lower, one hand presses the hand lever 9, whereby the locking piece 6 rotates in the bearing 5 and the locking pawl 7 reaches the position shown in dashed lines outside of the locking teeth of the support rod. In this position, the support bar can be lowered with the other hand. If the hand lets go of the lever 9, the pawl 7 falls under its own weight into the ratchet teeth of the support rod and prevents the same from sliding down. The support rod is raised by pulling it. At the upper end of the support rod is the support 10.

 

Claims (1)

PATENTANSPRUCH: Gerüstbock, dadurch gekennzeichnet, dass in einem oben durch Platten verbundenen Dreifuss eine T-förmige, mit Sperrzähnen ver sehene Tragstange längsverschiebbar gelagert ist, welche durch ein in der obern Ver- bindungsplatte drehbar gelagertes Sperrstück arretierbar ist. PATENT CLAIM: Scaffolding trestle, characterized in that a T-shaped support rod provided with locking teeth is mounted in a tripod connected at the top by plates, which can be locked by a locking piece rotatably mounted in the top connecting plate. UNTERANSPRUCH: Gerüstbock nach Patentanpruch, dadurch gekennzeichnet, dass das Sperrstück ausser der Sperrklinke, die in die Zähne der Trag stange eingreift, noch zwei Auflagenocken, die auf der obern Verbindungplatte auf liegen, und einen Handhebel zur Betätigung der Sperrldinke besitzt, ferner dadurch ge kennzeichnet, dass die Sperrklinke durch ihr Eigengewicht in die Sperrzähne der Trag stange einfällt. SUBSTANTIAL CLAIM: Trestle according to claim, characterized in that the locking piece besides the pawl which engages in the teeth of the support rod, has two support cams that rest on the upper connecting plate, and a hand lever for actuating the locking pawl, further characterized by it that the pawl falls due to its own weight in the ratchet teeth of the support rod.
