Description

Einrichtung zum senkrechten Verstellen und selbsttätigen Feststellen von Wandarmtischen. Die Erfindung betrifft eine Einrichtung zum senkrechten Verstellen und. selbsttätigen Feststellen :der an parallelen Tragschienen angebrachten Wandarmtische mit einer an der einen der Tragschienen schwingbar angeordneten Bremsstange, die durch eine an der anderen Schiene befestigte Lasche hindurchgreift.Device for vertical adjustment and automatic locking of wall arm tables. The invention relates to a device for vertical adjustment and. automatic locking: the wall arm tables attached to parallel mounting rails with a brake rod which is swingably arranged on one of the mounting rails and which reaches through a tab attached to the other rail.

Das Neue der Erfindung besteht darin, daß die Lasche als -ein gleichzeitig als Handhebel dienender, unter Wirkung einer Feder stehender Doppelhebel ausgebildet ist, der mittels eines BunKles die glatte Bremsstange mit geringem Spielraum derart umgreift, daß diese sich durch entsprechende Handeinstellung des Bremshebels zwecks Veränderung der Höhenstellung des Tischres innerhalb des Bundes verschieben. läßt. Beim Freigeben des Bremshebels werden infolge des hierbei in dem Bunde eintretenden und durch eine Feder unterstützten Eckens der Bremsstange der Bremshebel in der jeweiligen Stellung selbsttätig festgeklemmt und der Tisch damit in der gewünschten Höhenstellung festgehalten.The novelty of the invention is that the tab as -ein at the same time designed as a hand lever serving under the action of a spring double lever is that by means of a BunKles the smooth brake rod with little play in this way encompasses that this can be done by appropriate manual adjustment of the brake lever for the purpose Shift change of the height position of the table within the federal government. leaves. When releasing the brake lever, as a result of this occurring in the collar and by a spring supported corner of the brake rod of the brake lever in the automatically clamped in the respective position and the table in the desired position Height position held.

Es sind bereits Einrichtungen zum Einstellen der Wandarme zahnärztlicher Wandtische bekannt geworden, bei denen die Einstellung unter Vemittlung von Sperrzähnen erfolgt. Die Höhe der Einstellung dieser Tische hängt also von der Entfernung der Sperrzähne voneinander ab. Im Gegensatz hierzu kann der -Wandarmtisch nach der Erfindung in jeder beliebigen Höhenlage eingestellt werden.There are already dental facilities for adjusting the wall arms Wall tables have become known in which the setting is carried out by means of ratchet teeth he follows. So the height of the setting of these tables depends on the distance of the Ratchet teeth from each other. In contrast, the wall arm table according to the invention can be set at any altitude.

Auf der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt, und zwar zeigt Abb. r eine Seitenansicht des XV-andarmtisches in wagerechter Einstellung, Abb. z den gehobenen Tisch und in strichpunktierten Linien den gesenkten Tisch. Abb. 3 biss 5 zeigen die verschiedenen Stellungen zwischen der Bremsstange und dem Bremshebel bzw. dem Bremsbunde: Der Tisch i ist mittels des Trägers 2 an einer Schiene 3 befestigt, welche an der Führungsscheibe 9 hin und her verschiebbar ist. An dieser Scheibe 9 greifen die beiden Hebel 4 und 5 des Hebelparallelogramms gelenkig an.The subject of the invention is shown in one embodiment in the drawing shown, namely Fig. r shows a side view of the XV arm table in a horizontal position Setting, Fig. Z, shows the raised table and, in dash-dotted lines, the lowered one Table. Fig. 3 to 5 show the different positions between the brake rod and the brake lever or the brake collar: The table i is by means of of the carrier 2 attached to a rail 3, which on the guide disk 9 out and can be moved here. On this disc 9, the two levers 4 and 5 of the engage The lever parallelogram is articulated.

Die beiden Hebel 4 und 5 sind an der'Drehachse 6 gelenkig befestigt, die ihrerseits in den beiden an der Wandplatte 8 vorgesehenen Lagern 7 ruht. An dem Hebel 4 ist mittels des Zapfens i i ein Arm i o schwingbar angeordnet, welcher die Bremsstange 12 trägt.The two levers 4 and 5 are articulated to the axis of rotation 6, which in turn rests in the two bearings 7 provided on the wall plate 8. At the lever 4 an arm i o is arranged to swing by means of the pin i i, which the brake rod 12 carries.

An dem Hebel 5 ist im Zapfen 16 ein Doppelhebel 14, 15 gelagert, dessen oberes Ende bei 13 zu einem Bunde ausgestaltet ist, der die Bremsstange 12 mit geringem Spielraum umgreift. Der untere Arm 15 des Doppelhebels ist als Handgriff ausgebildet. Eine am Doppelhebel 14, 15 angeordnete Feder 17 ist bestrebt, den Doppelhebel 14, 15 und damit den Bund 13 in eine solche Stellung zu drehen., daß er die Bremsstange 12 festklemmt.On the lever 5, a double lever 14, 15 is mounted in the pin 16, the upper end is designed at 13 to form a collar, which the brake rod 12 with little Scope encompasses. The lower arm 15 of the double lever is designed as a handle. A spring 17 arranged on the double lever 14, 15 strives to lift the double lever 14, 15 and thus to rotate the collar 13 in such a position. That he the brake rod 12 stuck.

Die Abb.3 läßt dieses Festklemmen erkennen, während Abb. 4 veranschaulicht, daß sich die Stange 12 bei entsprechender Einstellung des Doppelhebels 14, 15 im Bunde 13 frei vor und zurück verschieben kann.Figure 3 shows this jamming, while Figure 4 shows that the rod 12 with the appropriate setting of the double lever 14, 15 in Bundles 13 can move freely back and forth.
