Abstract

An adjustable stool used by a doctor during a medical examination has a height control system with a handle (13) positioned immediately under the seat. In addition, a foot control (1) is mounted immediately under the frame (2) from which the castor wheels are suspended. The foot control is mounted on the bottom of the outer tube (3) inside which slides the seat supporting tube (12) forming part of a pneumatic piston and cylinder system. The hand control is swung against a crank arm (9) forming part of a mechanism for operating a latch (8) on top of the outer tube.

Description

BEZEICHNUNG: Arbeitssessel für einen behandelnden ArztNAME: Working chair for a doctor in charge

Die Erfindung betrifft einen Arbeitssessel für einen behandelnden Arzt mit einer kombinierten Hand - Fußsteuerung für eine zur Sitzhöhenverstellung eingebaute Gasfeder.The invention relates to a work chair for a treating person Doctor with a combined hand - foot control for a seat height adjustment built-in gas spring.

Es sind medizinische Arbeitssessel mit eingebauter Gasfeder bekannt, in denen nach zwei verschiedenen Systemen die Sitzhöhe verstellt wird. Entweder mit einem unter der Sitzfläche befindlichen Handhebel oder mit einem meist ringförmigen Schaltteller, angeordnet oberhalb eines fünfarmigen Fahrgestells zwecks Schaltung mit einem Fuß. Gemeinsam an beiden Systemen ist, daß über eine Hebelanordnung das Steuerventil einer Gasfeder betätigt wird. Wird das Steuerventil betätigt, schiebt die Gasfeder bei entlastetem Sitz denselben stufenlos aufwärts und fährt bei belastetem Sitz ab. Im Bereich des Hubes kann in jeder Stellung die Gasfeder und somit die Sitzfläche blockiert werden.Medical work chairs with built-in gas springs are known in which the seat height is adjusted according to two different systems. Either with a hand lever located under the seat or with a mostly ring-shaped one Indexing table, arranged above a five-armed chassis for the purpose of switching with one foot. What both systems have in common is that the Control valve of a gas spring is operated. If the control valve is actuated, it pushes the gas spring moves the same steplessly upwards when the seat is relieved and moves when the seat is loaded Sit down. In the area of the stroke, the gas spring and thus the The seat can be blocked.

Der Erfindung liegt die Aufgabe zugrunde, eine kombinierte Hand-Fußsteuerung zu schaffen, mit der in einfacher und sicherer Weise die Höhe des Sessels entweder mit der Hand oder mit dem Fuß vorgenommen wird, sodaß der Arbeitssessel für alle medizinischen Bereiche Verwendung findet.The invention is based on the object of a combined hand-foot control to create with the in a simple and safe way the height of the chair either is done by hand or foot, so that the work chair for everyone medical areas is used.

Gemäß der Erfindung ist nach beigefügter Zeichnung für den oben genannten Arbeitssessel vorgeschlagen, den ringförmigen Schaltteller 1 unterhalb des fünfarmigen Fahrgestells 2 anzuordnen. Bei dieser Anordnung wird das Betätigen des Schalttellers 1 mit dem Fuß bedeutend dadurch erleichtert, daß man speziell bei der zur Verstellung der Sitzfläche nach oben nötigen Entlastung des Sitzes, das Körpergewicht auf beide Füße verlagern kann, also nur den Absatz des Schaltfußes anheben muß, um den Schaltteller zu betätigen.According to the invention is according to the accompanying drawing for the above Working chair proposed the ring-shaped table top 1 below the five-armed To arrange chassis 2. With this arrangement, the actuation of the table top 1 with the foot significantly facilitated by the fact that one is specifically involved in the adjustment the seat surface upwards necessary relief of the seat, the body weight on both Can shift feet, so you only have to lift the paragraph of the switch foot to the table top to operate.

Bei der bekannten Anordnung des Schalttellers oberhalb des Fahrgestells, muß man bei dem vorher geschilderten Schaltvorgang sein Körpergewicht auf einen Fuß verlagern, um den Schaltfuß anheben und den Schaltteller betätigen zu können.With the known arrangement of the table top above the chassis, you have to put your body weight to one in the previously described switching process Shift foot to the Raise the switch foot and operate the table top to be able to.

Die beigefügte Zeichnung gibt einen Arbeitssessel mit kombinierter Hand - Fußsteuerung zum Teil im Schnitt wieder.The attached drawing gives a work chair with a combined Hand - foot control partly in the cut again.

Sie setzt sich wie folgt zusammen: Am Schaltrohr 3, das im Bereich des fünfarmigen PaVrgestells 2 für den Schaltweg ausgespart ist, befindet sich unterhalb des Fahrgestells 2 der Schaltteller 1.It is made up as follows: On the switching tube 3, the one in the area of the five-armed PaVrgestells 2 is cut out for the switching path, is located below of the chassis 2 of the table top 1.

Das Schaltrohr 3 ist durch zwei Kunststoffbuchsen 4 beweglich über dem Zylinder 5 gelagert. Oberhalb des Fahrgestells 2 ist im Schaltrohr 3 eine Druckfeder 6 angeordnet. Uber dem Zylinder 5 sitzt ein Ring 7 mit Lasche 8, an dem ein Winkelhebel 9 beweglich angebracht ist. Über dem Winkelhebel 9 sitzt der Anschlag 10 des Schaltrohrs 3. The switching tube 3 is movable over by two plastic bushings 4 the cylinder 5 stored. A compression spring is located in the switching tube 3 above the chassis 2 6 arranged. Above the cylinder 5 there is a ring 7 with a tab 8 on which an angle lever is attached 9 is movably attached. The stop 10 of the switching tube sits above the angle lever 9 3.

Die Zeichnung gibt einen Arbeitssessel in höchster Sitzposition wieder. Wird nun bei belastetem Sitz der Schaltteller 1 mit Schaltrohr 3 und Anschlag 10 nach unten bewegt, drückt der Winkelhebel 9 die Schaltstange 11, die am Handsteuerhebel 13 angeschweißt ist, nach außen parallel zum Gaslift 12. Dieser Vorgang bewirkt, daß das Steuerventil 14 des Gasliftes 12 betätigt wird, und somit die Sitzfläche des Arbeitssessels abfährt. The drawing shows a work chair in the highest sitting position. When the seat is loaded, the table top 1 with the switching tube 3 and stop 10 moved downwards, the angle lever 9 pushes the switching rod 11, which is on the hand control lever 13 is welded to the outside parallel to the gas lift 12. This process causes that the control valve 14 of the gas lift 12 is actuated, and thus the seat of the work chair moves down.

Unabhängig davon kann man auch mit dem Handsteuerhebel 13 den Schaltvorgang ausführen. Independently of this, the manual control lever 13 can also be used to switch the switching process carry out.
