Ende eines Hebelarmes angeordnetes höhenverstellbares ArbeitsgerätHeight-adjustable working device arranged at the end of a lever arm
Die Neuerung betrifft eine Lösbare Rastvorrichtung für ein am Ende eines Hebelarmes angeordnetes, höhenverstellbares &lgr; Arbeitsgerät.The innovation concerns a detachable locking device for a height-adjustable &lgr; working device arranged at the end of a lever arm.
Es ist bei verschiedenen Arbeitsgeräten, di? am Ende eines Hebelarmes angeordnet sind, bekannte, eine Rastvorrichtung vorzusehen, mit deren Hilfe das höhenverstellbare Arbeitsgerät in verschiedenen Stellungen arretierbar und aus der Arretierstellung wieder lösbar ist. So sind beispielsweise Fugenschneider für den Straßenbau bekannt, bei denen die höhenverstellbare Schneidscheibe am Ende eines Hebelarmes gelagert ist und das von der Schneidscheibe abgewandte Ende des Hebelarmes mit einer Rastvorrichtung verbunden ist, die beispielsweise über eine Gewindespindel, eine Zahnstange, eine Kolbenzylindereinheit oder einen Bowdenzug betätigbar ist.It is known for various tools that are arranged at the end of a lever arm to provide a locking device with the help of which the height-adjustable tool can be locked in different positions and released again from the locking position. For example, joint cutters for road construction are known in which the height-adjustable cutting disc is mounted at the end of a lever arm and the end of the lever arm facing away from the cutting disc is connected to a locking device that can be actuated, for example, via a threaded spindle, a rack, a piston-cylinder unit or a Bowden cable.
Bei den bekannten Ausführungsformen wird es als nachteilig empfunden, daß die Bedienung meist von Hand erfolgen muß, so daß der Bediener das von Hand zu haltende Gerät zeitweilig zum Teil freigeben muß, und daß die bekannten Vorrichtungen in ihrem Aufbau verhältnismäßig aufwendig und störanfällig sind.In the known embodiments, it is considered disadvantageous that the operation must mostly be carried out manually, so that the operator must temporarily release the device that is to be held by hand, and that the known devices are relatively complex in their construction and susceptible to failure.

' f\ Vorteilhaft ist am zum Arbeitsgerät weisenden Ende der \ Auftrittsfläche eine öse angeordnet, durch die das verjüngte j Ende des Winkelhebels mit Spiel ragend angeordnet ist. ' f\ Advantageously, an eyelet is arranged at the end of the tread facing the implement, through which the tapered end of the angle lever is arranged to protrude with some play.
. Der Rastbolzen ist vorteilhaft gelenkig mit dem zugeordneten i Ende des Winkelhebels verbunden.. The locking bolt is advantageously connected in an articulated manner to the associated i end of the angle lever.
I Nach einer vorteilhaften Ausführungsform ist der Rastbolzen in ' einer Hülse geführt und mit einer Rückholfeder wirksam verbunden.I According to an advantageous embodiment, the locking bolt is guided in a sleeve and is effectively connected to a return spring.

Nach Fig* 1 ist ein Fugenschneider mit einer höhenverstellbaren Schneidscheibe (1) ausgerüstet. Die Schneidscheibe (1) sitzt am Ende eines Hebelarmes (2), an dessen anderem Ende eine Auftrittsfläche (3) angeordnet ist. Nahe der Auftrittsfläche (3) befindet sich eine Rastvorrichtung (4), mit deren Hilfe der Hebelarm (2) in verschiedenen Stellungen arretierbar ist.According to Fig. 1, a joint cutter is equipped with a height-adjustable cutting disc (1). The cutting disc (1) is located at the end of a lever arm (2), at the other end of which a tread surface (3) is arranged. Near the tread surface (3) there is a locking device (4) with the help of which the lever arm (2) can be locked in various positions.
Die Rastvorrichtung (4), die ifi vergrößerter Darstellung in Fig. 2 gezeigt ist, besteht aus einer Zahnstange (5)> die im Abstand angeordnete Rastnuten (6) aufweist, in die ein Rastbolzen (7) einrastbar ist.The locking device (4), which is shown in an enlarged view in Fig. 2, consists of a rack (5)> which has locking grooves (6) arranged at a distance into which a locking bolt (7) can be engaged.
Der Rastbolzen (7) ist in einer Hülse (8) geführt und sein aus der Hülse herausragendes Ende durchdringt den Hebelarm (2). Der Rastbolzen (7) ist an seinem anderen Ende über einen Stift (9) gelenkig mit einem Schenkel (10) eines Winkelhebels (11), der um eine Drehachse (12) kippbar ist, verbunden. Der andere Schenkel (13) des Winkelhebels (11) ragt mit seinem freien, verjüngten Ende (14) durch eine öse (15), die mit der Auftrittsfläche (3) fest varbunden ist.The locking bolt (7) is guided in a sleeve (8) and its end protruding from the sleeve penetrates the lever arm (2). The locking bolt (7) is connected at its other end via a pin (9) in an articulated manner to a leg (10) of an angle lever (11) that can be tilted about a rotation axis (12). The other leg (13) of the angle lever (11) protrudes with its free, tapered end (14) through an eyelet (15) that is firmly connected to the tread surface (3).
Die Auftrittsfläche (3) ist um eine Drehachse (16) mit dem Hebelarm (2) verbunden.The tread (3) is connected to the lever arm (2) around a rotation axis (16).
Wie Fig. 3 erkennen läßt, ist in der Hülse (8) eine Rückholfeder (17) angeordnet= Die Oberseite (18) der Hülse (8)As can be seen in Fig. 3, a return spring (17) is arranged in the sleeve (8) = The top (18) of the sleeve (8)

&iacgr; Auftrittsfläche (3). i&iacgr; tread surface (3). i
Durch Auftritt auf das zum Arbeitsgerät zeigende Ende der kjftrittsfLache (3) wird mit HiLfe der öse (15) das Ende (U) des Winkelhebels (11) nach unten gedrückt/ so daß der Winkelhebel <11) eine Drehung derart erfährt/ daß der Schenkel (10) des WinkeLhebeLs (11) nach außen gezogen wird und dabei den RastboLzen (7) aus seiner Ar retierstelLung nach Fig. 3 löst.By stepping on the end of the tread surface (3) facing the implement, the end (U) of the angle lever (11) is pressed downwards with the aid of the eyelet (15) so that the angle lever (11) is rotated in such a way that the leg (10) of the angle lever (11) is pulled outwards and in doing so releases the locking bolt (7) from its locking position according to Fig. 3.
Sobald die Auftrittsfläche (3) wieder freigegeben wird/ fährt der Rastbolzen (7) aufgrund der Einwirkung der Rückholfeder (17) wieder aus, um den Hebelarm (2) in gewünschter Stellung festzulegen.As soon as the tread (3) is released again, the locking bolt (7) extends again due to the action of the return spring (17) in order to fix the lever arm (2) in the desired position.
