Description

Die vorliegende Erfindung betrifft einen höhenverstellbaren Arbeitssitz.The present invention relates to a height-adjustable working seat.

Sitze mit einer Vorrichtung zur Absenkung oder Anhebung der Sitzhöhe sind seit langem bekannt und sind in verschiedenen Ausführungen als Stuhl oder Hocker, feststehend oder auf Rollen, weltweit millionenfach in Gebrauch. Bei diesen Sitzen dient die Mechanik nur zur Anpassung der Sitzhöhe an eine gegebene Arbeitshöhe z.B. Schreibtisch, Werkbank unter Berücksichtigung der Körpergröße des ständigen Benutzers. Die einmal gefundene Position des Sitzes bleibt normalerweise unverändert.Seats with a device for lowering or raising the seat height have long been known and are in various versions as a chair or stool, fixed or on wheels, millions of times in use. In these seats, the mechanism only serves to adjust the seat height to a given working height, e.g. Desk, workbench, taking into account the body size of the permanent user. The once found position of the seat usually remains unchanged.

Bei Tätigkeiten ohne vorgegebene Arbeitshöhe z.B. im medizinischen oder zahnärztlichen Bereich erfolgt die Anpassung des zu untersuchenden Körpers an die Sitzhöhe des Untersuchers durch Senken, Anheben, Neigen oder Kippen. Die Sitzhöhe selbst bleibt meistens unverändert.For activities without a predetermined working height, e.g. In the medical or dental field, the adjustment of the body to be examined to the seat height of the examiner by lowering, raising, tilting or tilting. The seat height itself remains mostly unchanged.

Über die genannten Beispiele hinaus gibt es sicherlich noch eine unbekannte Zahl von Anwendungsgebieten.Beyond the examples given, there is certainly an unknown number of application areas.

Wenn bei diesen Sitzen die Sitzhöhe auf den tiefsten Punkt abgesenkt wurde, ist es für einen steifen, korpulenten und/oder gehandicapten Benutzer praktisch unmöglich, den Sitz aus dieser Position im Sitzen anzuheben. Er ist gezwungen aufzustehen, um das zu bewerkstelligen. Außerdem sind diese Sitze meistens ziemlich schwer, sperrig und somit unhandlich, so dass sie bestimmungsgemäß nur in ebenen, trockenen und begrenzten Innenbereichen einsetzbar sind.With these seats, when the seat height has been lowered to the lowest point, it is virtually impossible for a stiff, corpulent and / or handicapped user to raise the seat from that position while sitting. He is forced to get up to do that. In addition, these seats are usually quite heavy, bulky and thus unwieldy, so they are intended to be used only in even, dry and limited indoor areas.

Ein Beispiel für die obigen Ausführungen ist der unter dem deutschen Gebrauchsmuster mit der Nummer DE 7 404 690U geführte Stahlrohrhocker zur Verwendung als Büromöbel, Küchenmöbel od.dgl. Er ist nur für den Innenbereich konzipiert,ist sperrig und unhandlich.Die Sitzhöhe kann zwar unter Belastung abgesenkt, aber nicht angehoben werden(Seite 8 der Beschreibung, 1 Absatz), was die Gebrauchsfähigkeit insbesondere für ältere Menschen stark einschränkt.An example of the above is the one under the German utility model number DE 7 404 690U Guided tubular steel stools for use as office furniture, kitchen furniture or the like. It is designed for indoor use only, is bulky and unwieldy. The seat height can indeed be lowered under load, but not raised (page 8 of the description, 1 paragraph), which greatly limits the usability, especially for older people.

Die Patentschrift De 7 000 167U zeigt auch einen Stuhl, insbesondere Arbeitsstuhl. Die Schrift befaßt sich jedoch ausschließlich mit der Konstruktion und Kippwinkelverstellung des Sitzes und der Rückenlehne und enthält keine detaillierten Angaben über die Höhenverstellung des Stuhles. Im Prinzip gelten jedoch auch hier die für den Hocker im vorigen Absatz gemachten Aussagen.The patent De 7 000 167U also shows a chair, especially work chair. The document, however, deals exclusively with the construction and tilt angle adjustment of the seat and the backrest and does not contain any detailed information about the height adjustment of the chair. In principle, however, here are the statements made for the stool in the previous paragraph.

Mit der vorliegenden Erfindung soll ein Arbeitssitz bereitgestellt werden für die Durchführung von verschiedenen Arbeiten , mit dem eine Absenkung oder Anhebung des Sitzes während des Sitzens möglich ist.With the present invention, a working seat to be provided for the performance of various work, with a lowering or raising of the seat during sitting is possible.

Gemäß der vorliegenden Erfindung besteht der Arbeitssitz aus einem Schalensitz, einem Teleskoprohr, aus einer Feder und einem Tellerfuß.According to the present invention, the working seat consists of a bucket seat, a telescopic tube, a spring and a disc base.

Der Arbeitssitz mit dem Tellerfuß braucht wenig Platz, ist leicht, handlich und kann mit einer Hand bequem an jeden Ort getragen werden. Damit ist er für viele Tätigkeiten insbesondere im Garten, aber auch im Haus, Hof, Betrieb und in der Freizeit einsetzbar.The working seat with the base plate takes up little space, is light, handy and can be easily carried to any place with one hand. This makes it suitable for many activities, especially in the garden, but also in the house, yard, operation and leisure.

Die Höhe des Arbeitssitzes beträgt ca. 50 cm wie ein Stuhl und kann um ca. 10 cm abgesenkt werden, so dass Tätigkeiten bequem in einer Höhez wischen ca. 100 cm und Boden möglich sind. Die Besonderheit der hier vorliegenden Erfindung beruht darauf, dass die Mechanik für die Arretierung und Dearretierung der Zahnstangen mittels der Zahnrasten so konzipiert ist, dass die Veränderung der Sitzhöhe während des Sitzens erfolgen kann und dass insbesondere das Aufstehen in der Ausgangshöhe von ca. 50 cm möglich ist.The height of the working seat is approx. 50 cm like a chair and can be lowered by approx. 10 cm, so that activities in a height of approx. 100 cm and ground are possible. The peculiarity of the present invention is based on the fact that the mechanism for locking and Dearretierung the racks by means of toothed racks is designed so that the change in seat height can be made while sitting and that in particular getting up in the initial height of about 50 cm possible is.

Damit ist der Arbeitssitz besonders geeignet, aber nicht nur, für ältere und/oder gehandicapte Menschen, die nicht mehr für längere Zeit gebeugt, hockend oder knieend tätig sein können und denen auch ein Hinsetzen auf einen niedrigen Hocker und das Wiederaufstehen schwer fällt.Thus, the working seat is particularly suitable, but not only, for older and / or handicapped people who can not be bent, crouching or kneeling for a long time and who also sit down on a low stool and getting up is difficult.

Bei einem Vergleich der beiden Stühle mit dem Arbeitssitz wird offenbar, dass der Arbeitssitz mit der Arretierungs- und Dearretierungsmechanik und dem Tellerfuß gegenüber diesen für einen ganz anderen Einsatzbereich konzipiert ist, wesentlich bessere Eigenschaften aufweist und ein wesentlich größeres Gebrauchsspektrum hat.A comparison of the two chairs with the working seat, it is apparent that the working seat is designed with the Arretierungs- and Dearretierungsmechanik and the Tellerfuß opposite this for a very different application, has much better properties and has a much wider range of uses.

Die Erfindung wird anhand von schematischen Darstellungen mit den folgenden weiteren Einzelheiten erläutert.The invention will be explained with reference to schematic representations with the following further details.

Es sind dies im Einzelnen :

Zur Lösung der erfindungsgemäßen Aufgabe besteht der Arbeitssitz(1) aus einem Schalensitz(30),einem Teleskoprohr(2,10), aus einer Feder(13) und einem Tellerfuß(20).To achieve the object according to the invention, the working seat (1) consists of a bucket seat (30), a telescopic tube (2, 10), a spring (13) and a disc base (20).

Das Teleskoprohr(2, 10) ist das Hauptteil des Arbeitssitzes(1). Es besteht aus dem oberen(10) und dem unteren(2) Teleskoprohr und ist zwischen Schalensitz(30) und Tellerfuß(20) angeordnet.The telescopic tube (2, 10) is the main part of the working seat (1). It consists of the upper (10) and the lower (2) telescopic tube and is arranged between bucket seat (30) and disc base (20).

Im Zwischenraum zwischen dem unteren(2) und dem oberen(10) Teleskoprohr befinden sich im oberen Teil zwei an der Innenwand des unteren Teleskoprohres(2) befestigte Zahnstangen(4), in die zwei bewegliche gegenüber befindliche Zahnrasten(14) greifen, die über eine Mechanik von einem Betätigungshebel(17) am Kopf des oberen Teleskoprohres(1 0) betätigt werden und das Absenken und Anheben des Sitzes(1) ermöglichen.In the space between the lower (2) and the upper (10) telescopic tube are located in the upper part of two on the inner wall of the lower telescopic tube (2) fixed racks (4), in the two movable opposing toothed ratchets (14) engage over a mechanism of an actuating lever (17) on the head of the upper telescopic tube (1 0) are actuated and allow the lowering and raising of the seat (1).

In dem Zwischenraum zwischen dem oberen(10) und unteren(2) Teleskoprohr befindet sich eine Feder(13), die beim Absenken des Sitzes(1) gespannt wird und dann das Anheben unterstützt.In the space between the upper (10) and lower (2) telescopic tube is a spring (13), which is tensioned when lowering the seat (1) and then supports the lifting.

Auf das obere Teleskoprohr(10) ist ein Abdeckblech(27) geschraubt, auf dem der nicht näher dargestellte Schalensitz(30) befestigt ist.On the upper telescopic tube (10) a cover plate (27) is screwed, on which the bucket seat (30), not shown, is attached.

Unter dem Abdeckblech(27) ist ein Gurt(31) befestigt, der eine Standortveränderung mit dem Sitz(1) ohne aufzustehen ermöglicht.Under the cover plate (27) a belt (31) is fixed, which allows a change of location with the seat (1) without getting up.

Unter dem unteren Teleskoprohr(2) ist der Tellerfuß(20), bestehend aus einer runden Metallplatte(21), mit einem Scharnier(22) angeschraubt. Auf der Platte ist eine Arretierungsmechanik(23-25 )angebracht, mit der der Arbeitssitz(1) in der Senkrechten fixiert wird. Über die Metallplatte ist eine nicht näher dargestellte Gumminoppenkappe(26) gezogen, die dem Sitz(1) Rutsch und Standfestigkeit verleiht.Under the lower telescopic tube (2), the disc base (20) consisting of a round metal plate (21), with a hinge (22) screwed. On the plate, a locking mechanism (23-25) is mounted, with which the working seat (1) is fixed in the vertical. Over the metal plate is pulled a rubber stopper cap (26), not shown, which gives the seat (1) slip and stability.

Um den Sitz zu betätigen, wird die Arretierung der beweglichen Zahnrasten(14) mit den fixen Zahnstangen(4) nach einer leichten Anhebung des Körpers durch eine Schwenkbewegung des Betätigungshebels(17) im Uhrzeigersinn gelöst. Durch diese Bewegung werden die Zahnrasten(14) von den Zahnstangen(4) weg geschwenkt und geben das obere Teleskoprohr(10) für das Absenken oder Anheben frei.To operate the seat, the locking of the movable toothed rests (14) with the fixed racks (4) after a slight lifting of the body by a pivoting movement of the actuating lever (17) is released in a clockwise direction. By this movement, the toothed rests (14) are pivoted away from the racks (4) and release the upper telescopic tube (10) for lowering or lifting.

Nach Beendigung des Absenkvorganges in der gewünschten Höhe werden die Zahnrasten(14) mittels des Betätigungshebels(17) zurückgeschwenkt und wieder mit den Zahnstangen(4) verbunden.After completion of the lowering process in the desired height, the toothed rests (14) by means of the actuating lever (17) are swung back and connected to the racks (4).

Zum Anheben des Sitzes(30) wird der Druck des Körpergewichtes durch leichtes Anheben reduziert, die Zahnrasten(14) werden mit Hilfe des Betätigungshebels(17) wieder von den Zahnstangen(4) gelöst und der Sitz(30) wird mit dem Druck der gespannten Feder(13) angehoben. Anschließend werden die Zahnrasten(14) wieder mit dem Betätigungshebel(17) zurückgeschwenkt.To lift the seat (30), the pressure of the body weight is reduced by slightly lifting, the toothed rests (14) are released from the racks (4) again by means of the operating lever (17) and the seat (30) is tensioned with the pressure of Spring (13) raised. Subsequently, the toothed rests (14) are swung back again with the actuating lever (17).
