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.
