Description
Die Erfindung betrifft einen Bürostuhl mit einem Sitzflächenträger, der um eine horizontal und quer verlaufende Achse in einem Tragrahmen neigungsverstellbar gelagert ist, wobei die Neigungsverstellung mittels einer Exzenter-Drehwelle erfolgt, die mit mindestens einem konzentrischen Wellenteil in einem Drehlager des Tragrahmens gelagert ist und die mindestens einen exzentrischen Wellenteil (Exzenter) aufweist, der in einem Exzenterlager des Sitzflächenträgers läuft derart, daß eine vom Sitzbenutzer ausgeführte Drehwinkelverstellung der Drehwelle die Neigung des Sitzflächenträgers relativ zum Tragrahmen verändert.The invention relates to an office chair a seat support that is one horizontal and transverse axis in a support frame with adjustable inclination is, the tilt adjustment by means of an eccentric rotary shaft, those with at least one concentric Shaft part in a pivot bearing of the support frame is stored and the at least an eccentric shaft part (eccentric) has that in an eccentric bearing Seat carrier runs such that a Angle adjustment made by the seat user the inclination of the rotary shaft Seat support relative to the support frame changed.
Solche Exzenterverstellungen für eine Sitzneigungsverstellung von Bürostühlen sind bekannt. Sie sind im Regelfall unabhängig von anderen Einstellmöglichkeiten des Bürostuhles und auch unabhängig von einer gegebenenfalls vorhandenen Synchronmechanik des Bürostuhles zu betätigen.Such eccentric adjustments for one Seat tilt adjustment of office chairs are known. As a rule, they are independent of other setting options of the office chair and also regardless of a possibly existing synchronous mechanism of the office chair.
Exzenterverstellungen sind in bestimmten Grenzen selbsthemmend, d.h. sie verändern ihre vom Sitzbenutzer eingestellte Drehwinkelposition nicht. Das gilt jedoch dann nicht mehr, wenn die Exzenter, die in einem Exzenterlager des Sitzflächenträgers positioniert sind, mit einem zu hohen Körpergewicht des Sitzbenutzers oder mit einem zu starken dynamischen Verhalten des Sitzbenutzers belastet sind, das sich z.B. in Erschütterungen der Exzenterlagerung auswirkt. Dann kann es zu unerwünschten Verstellungen der Sitzflächenneigung kommen. Eccentric adjustments are certain Limits self-locking, i.e. they change their angle of rotation position set by the seat user Not. However, that applies then no longer when the eccentrics that in an eccentric bearing of the seat support are positioned with a excessive body weight of the seat user or with a too strong dynamic Behavior of the seat user is burdened that are e.g. in tremors the eccentric bearing affects. Then can it leads to unwanted adjustments of the Seat inclination come.
Aufgabe der Erfindung ist es, einen Bürostuhl der vorgenannten Art mit einer Neigungsverstellung der Sitzfläche so zu verbessern, daß unerwünschte Verstellungen der Sitzflächenneigung nicht auftreten können.The object of the invention is an office chair of the aforementioned type with a Tilt adjustment of the seat so to improve that unwanted pretense not the seat inclination may occur.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Exzenter-Drehwelle einen Handhabungsteil aufweist, der relativ zum Funktionsteil der Drehwelle rotierbar ist, und daß zwischen dem Funktionsteil der Drehwelle und dem Tragrahmen ein ausrückbarer Sperreingriff vorhanden ist, der im nicht-ausgerückten Zustand die Drehwinkelverstellung des Funktionsteils der Drehwelle blockiert, wobei ein erster Drehwinkelbereich der vom Sitzbenutzer am Handhabungsteil der Drehwelle ausgeführten Drehwinkelverstellung mittels eines Umsetzungsgetriebes in eine Ausrückbewegung des Sperreingriffs umgesetzt wird und ein nachfolgender zweiter Drehwinkelbereich der vom Sitzbenutzer am Handhabungsteil der Drehwelle ausgeführten Drehwinkelverstellung über einen Mitnehmeranschlag zwischen dem Handhabungsteil und dem Funktionsteil der Drehwelle eine analoge Drehwinkelverstellung des Funktionsteils der Drehwelle bewirkt. This object is achieved according to the invention solved that the eccentric rotary shaft one Has handling part that is relative to Functional part of the rotary shaft is rotatable, and that between the functional part of the Rotary shaft and the support frame a disengageable There is locking intervention when not disengaged, the angle of rotation adjustment of the functional part of the Blocked rotation shaft, being a first Angle of rotation range of the seat user on Handling part of the rotary shaft executed Angle of rotation adjustment by means of a conversion gear in a disengagement movement of the blocking intervention is implemented and a subsequent second angle range that of the seat user on the handling part the rotary shaft adjustment via a driver stop between the handling part and the Functional part of the rotary shaft an analog Rotation angle adjustment of the functional part the rotating shaft.
Ein nach der Lehre der Erfindung gefertigter Bürostuhl hat zunächst den Vorteil, daß dessen Bedienungsfreundlichkeit beim Verstellen der Sitzflächenneigung erhalten bleibt. Der Sitzbenutzer betätigt wie bisher lediglich eine Drehwelle und verstellt dadurch die Sitzflächenneigung in der gewünschten Weise. Der nach der vorstehenden Lehre der Erfindung definierte Übergang zwischen einem ersten und zweiten Drehwinkelbereich der Drehwelle bleibt vom Sitzbenutzer im Normalfall unerkannt und unbemerkt, da die nacheinander durchlaufenen Drehwinkelbereiche der Drehwelle lediglich interne Funktionsabläufe betreffen.One made according to the teaching of the invention Office chair initially has the Advantage that its ease of use when adjusting the seat inclination preserved. The seat user operates only one rotary shaft as before and thereby adjusts the seat inclination in the way you want. According to the above teaching of the invention defined transition between a first and second rotation angle range the rotating shaft remains in the seat user Normally undetected and unnoticed, there the successive rotation angle ranges the rotary shaft only internal Functional processes concern.
Im ersten Drehwinkelbereich wird ein Sperreingriff entarretiert, d.h. ausgerückt, der ohne aktuelle Betätigung der Drehwelle permanent im Eingriff ist und dadurch jede unerwünschte Verstellung des oder der Exzenter der Drehwelle, deren jeweiliger Exzenterhub die Sitzflächenneigung bestimmt, wirksam verhindert.In the first rotation angle range there is a lockout intervention unlocked, i.e. disengaged, the one without current actuation of the rotary shaft is permanently engaged and therefore everyone unwanted adjustment of the or Eccentric of the rotary shaft, its respective Eccentric stroke determines the seat inclination, effectively prevented.
Im zweiten Drehwinkelbereich ist dann der Sperreingriff ausgerückt, so daß in diesem Drehwinkelbereich über einen Mitnehmeranschlag der jeweilige Exzenterhub verstellt werden kann. In the second range of rotation angle is then Lockout disengaged so that in this Angle of rotation range via a driver stop the respective eccentric stroke is adjusted can be.
Eine besonders zweckmäßige Konstruktion des Sperreingriffs besteht nach Anspruch 2 darin, daß dieser in Form einer auf dem Funktionsteil der Drehwelle drehfest aufsitzenden Stirnradverzahnung ausgebildet ist, die im nicht-ausgerückten Zustand mit einer am Tragrahmen ortsfest befestigten Stirnradverzahnung im Eingriff ist, wobei die auf dem Funktionsteil der Drehwelle aufsitzende Stirnradverzahnung durch eine axiale Verschiebebewegung auf der Drehwelle gegen den Druck einer Zuhaltefeder ausrückbar ist. Solch ein Sperreingriff zwischen dem Funktionsteil der Drehwelle und dem Tragrahmen ist einfach und kostengünstig herzustellen.A particularly useful construction the locking intervention exists according to claim 2 in that this is in the form of a Functional part of the rotating shaft Helical gear teeth formed is that in the non-disengaged state with one fixed to the supporting frame Spur gear toothing is engaged, whereby on the functional part of the rotary shaft sitting spur gear teeth by a axial displacement movement on the rotary shaft can be disengaged against the pressure of a locking spring is. Such a lockout between the functional part of the rotary shaft and the support frame is easy and inexpensive to manufacture.
Das gilt auch für das Umsetzungsgetriebe, das im ersten Drehwinkelbereich die Drehbewegung des Handhabungsteils der Drehwelle in eine axiale Ausrückbewegung des Sperreingriffs umsetzt. Nach Anspruch 3 besteht eine einfache Ausführungsform eines solchen Umsetzungsgetriebes aus einer oder mehreren Anlaufschrägen, die an den aneinanderliegenden stirnseitigen Anlageflächen des Handhabungsteils und des Funktionsteils der Drehwelle angeordnet sind.This also applies to the conversion gear, that in the first rotation angle range, the rotary movement the handling part of the rotating shaft in an axial disengagement movement of the locking engagement implements. According to claim 3 a simple embodiment of such Implementation gear from one or more Sloping ceilings on the adjacent front contact surfaces of the handling part and the functional part of the rotary shaft are arranged.
Diese Anlaufschrägen können in beide Drehrichtungen der Drehwelle gleich ausgebildet sein, so daß der Sitzbenutzer die Drehwelle wahlweise in die eine oder andere Drehrichtung rotieren kann und immer sein gewünschtes Ziel einer Neigungsverstellung der Sitzfläche erreicht.These bevels can be turned in both directions the rotary shaft is the same be so that the seat user the rotating shaft optionally in one or the other direction of rotation can and always rotate desired target of an inclination adjustment reached the seat.
