Description

Bezeichnung: Fußsteuerung für medizinische Arbeitssessel.Designation: Foot control for medical work chairs.

(für den Arzt) B E S C H R E I B U N G. (for the doctor) B E S C H R E I B U N G.

Auf dem Markt werden medizinische Arbeitssessel angeboten, in denen nach verschiedenen Systemen, die Sitzhöhe verstellt werden kann.Medical work chairs are offered on the market in which the seat height can be adjusted according to various systems.

Spindeln, sowie verschiedene Arten von Rastenverstellungen sind bekannt. In Jüngster Zeit setzt sich die Gasfeder immer mehr durch, wobei die blockierbare Gasfeder bevorzugt wird. Über einen Handhebel, der meist unter dem Sitz angebracht ist, wird das Steuerventil betätigt, wobei, bei entlastetem Sitz, die Gasfeder denselben stufenlos in die Höhe scheibt und bei belastetem @itz Abfährt. Im Bereich des Hubes kann in jeder Stellung die Gasfeder und somit die Sitzfläche blockiert werden. Durch die Verwendung der Gasfeder kann die @itzhöhe schnell und exakt, mit einem Maximum an Bedienungskomfort, verstellt werden. In letzter Zeit taucht allerdings eill n@ es Problem auf. Hat zum Beispiel, ein Chirurg seinen Arbeitssessel über den Handhebel in die richtige Sitzhöhe gesteuert, kann er nun nach dem Sterilisieren der H@nde mit der Arbeit beginnen. Soll nun aber, aus irgend welchen Erfordernissen, die Sitzhöhe korrigiert werden, muß der Chirurg jedesmal die Hände flisch sterilisieren. Dies ist serh zeitraubend und stört den Ablauf einer Operation empfindlich.Spindles and various types of notch adjustments are known. In recent times the gas spring has become more and more popular, with the lockable Gas spring is preferred. Via a hand lever, which is usually attached under the seat is, the control valve is actuated, with the gas spring the same when the seat is unloaded Steplessly upwards and descends when the @itz is loaded. In the area of the hub the gas spring and thus the seat can be blocked in any position. By the use of the gas spring can adjust the height quickly and precisely, with a maximum ease of use, can be adjusted. Recently, however, eill n @ there problem on. For example, a surgeon has his work chair using the hand lever controlled to the correct seat height, he can now after sterilizing the hands start working. But now, for whatever requirements, the seat height should be are corrected, the surgeon has to sterilize the hands each time. this is very time-consuming and disrupts the course of an operation.

Dieses Problem haben wir aufgegriffen und nach vielen und umfangreichen Versuchen mit einer einwandfrei funktionierenden Fußsteuerung gelöst. Die beigefügte Zeichnung gibt die Fußsteuerung, zum Teil zum besseren Verständnis, im schnitt wieder. die setzt sich folgendermaden zusammen: Der Schaltteller (1) ist mit dem Schaltrohr (2) durch Schweißung verbunden. Dieses Schaltrohr (2) ist durch zwei wartungsfreie Kunststoffbüchsen (3) beweglich gelagert. Am Schaltteller (1) ist der Schaltstößel (4) befestigt, welcher im Fahr0estellfuß (5) durch eine Plastikbüchse (6) geführt wird. Da die Sitze der Arbeitssessel drehbar sind, kann durch die Anordnung des Schalttellers (1) der Arbeitssessel beliebig in jede Stellung am Umfang, leicht mit dem Fuß, speziell mit dem Absatz, geschaltet werden. Wird nun ein leichter Druck auf den Schaltteller (1) ausgeübt, bewegt sich dieser abwärts und schaltet über den Schaltstößel (4) und den Kipphebel (7)das Steuerventil (8) der Gasfeder (9), wobei die Entlastungsfeder (lo) zusammengedrückt wird. Wird der Schaltteller (1) entlastet, drückt das federbelastete Steuerventil (8) unterstützt von der Entlastungsfeder (io) den Schaltteller (1) in die Ausgangsposition zurück, wobei gleichzeitig die Gasfeder (9) blockiert wird.We have taken up this problem and after many and extensive Trying to solve the problem with a perfectly functioning foot control. The enclosed The drawing shows the foot control in section, partly for better understanding. it is made up as follows: The table top (1) is with the switching tube (2) connected by welding. This switching tube (2) is maintenance-free by two Plastic bushings (3) movably mounted. The switch plunger is on the table top (1) (4), which is guided through a plastic bushing (6) in the Fahr0estellfuß (5) will. Since the seats of the work chairs are rotatable, the arrangement of the Table top (1) of the work chair in any position on the circumference, easily be switched with the foot, especially with the heel. Now there is a slight pressure exerted on the table top (1), it moves downwards and switches over the switch tappet (4) and the rocker arm (7) the control valve (8) of the gas spring (9), whereby the relief spring (lo) is compressed. If the table top (1) relieved, the spring-loaded control valve (8) presses supported by the relief spring (io) return the table top (1) to the starting position, while at the same time the Gas spring (9) is blocked.
