Definitions
- the invention relates to a chair, in particular office chair, with a backrest which is infinitely adjustable in its inclined position relative to a seat and pretensioned in one of its end positions, which is held in its inclined positions by a frictional multi-plate clutch which has at least one tension spring acting on the plates and which can be actuated by means of a handle lever arranged below the seat surface, the at least one tension spring being arranged concentrically on an axially adjustable bearing pin which is guided through slots in the clutch plates and forms an abutment for the tension spring.
- Frictional multi-plate clutches for the backrests of office chairs are already known in various embodiments.
- the multi-plate clutch is actuated by the chair user by means of a screw nut, with the disadvantage that the strength of the frictional connection depends on the rotational position of a clamping nut and thus ultimately on the force of an operator.
- a construction with the above features and with the power of a chair user independent frictional engagement of the multi-plate clutch is known from DE-PS 29 27 377.
- this construction does not take into account the existing requirement in modern office chairs for a compact structure and the possibility that a chair user can rock freely with the backrest without constantly having to operate a lever.
- the invention is therefore based on the object of designing a chair with the features mentioned at the beginning of a device for tilting the backrest in such a way that the adjusting device allows a compact structure with few individual parts with optional locking or releasing the backrest.
- the handle lever is connected to a release cam which acts on a link part which is coupled to the axially adjustable bearing pin and which has a latching recess for the release cam at least in one of its end positions.
- the release cam connected to the handle lever can be pivotable about a fixed axis and can rest against a profiled surface of the link part, which can be designed as a driving connection with the axially adjustable bearing pin in both directions, pivotable about a fixed axis rocker arm.
- both the actuation of the friction multi-plate clutch and its locking in its release position or its clutch position are achieved solely by these two parts in the chair designed according to the invention Release cam and the link part, reached without additional safety parts. This results in a space-saving, compact design of the friction clutch and their actuating part possible.
- the pivotable release cam can have a locking lug, which in both end positions of the release cam fits into a locking recess of the profiled contact surface of the rocker arm, which has an oblique sliding surface leading to the rocking movement of the rocker arm between its locking recesses.
- the trigger cam in its two pivoting directions can always be held against the rocker arm, which remains exposed to the action of the tension spring due to its driving coupling with the bearing pin - albeit with changing spring force.
- the pivot bearing of the rocker arm can also be designed as an open bearing, expediently consist of a bearing half-shell, in which the rocker arm engages appropriately with a bearing projection having a partial circular cross section. The subsequent formation of bearing bores and the use of a separate bearing pin can therefore be omitted.
- the construction according to the invention allows the few individual parts to be produced in their final shape, completely or largely without post-processing of these parts.
- Fig. 1 shows part of a chair frame of a seat support plate 10 and a vertical bearing plate 11 connected to the seat support plate and a horizontal mounting plate 12 of the seat support part of the chair frame.
- a support arm 13 can be seen from a backrest support, to which, in the construction shown, a second, identical support arm, not shown, which runs parallel and at a distance from it is associated.
- Both support arms can be pivoted about a pivot axis 14 arranged in the bearing plate 11 about a limited angular range which can be seen at an elongated hole 15 of the bearing plate 11, and are mounted so as to be continuously lockable in this pivoting region.
- FIGS. Fig. 1 shows that long plates 17 of the multi-plate clutch are also mounted on the pivot axis 14 for the support arms 13 and with their ends protruding from the coupling 16 are connected to each other by a rod 18, which through the already mentioned, the inclination limiting slot 15th protrudes in the bearing plate 11.
- a spring torsion spring 19 pushed onto the pivot axis 14 engages the rod 18 with its one spring end 19.1.
- the other spring end 19.2 is supported on the mounting plate 12.
- the screw torsion spring 19 causes a pretension via the rod 18 the support arms 13 in a front end position of the backrest support with its support arms 13, which is shown in Fig. 1.
- the long fins 17 with large openings 17.1 are pushed with a known interposition of short fins 20 over a bearing pin 21 which is axially displaceably mounted in a coupling housing 22 fastened on the mounting plate 12.
- the disk pack 17/20 of the disk clutch lies on the one hand against a fixed wall 23 of the clutch housing 22 and is limited on the other hand by a thrust washer 24 which is also pushed onto the bearing pin 21 and which is simultaneously guided in a bearing opening 25 of the bearing housing 22.
- disc springs 26 - On the outside of the thrust washer 24 there are disc springs 26 - here four disc springs - which are also pushed onto the bearing pin 21 and whose other abutment is formed by a clampable screw nut 27 which is screwed onto a threaded end 21.1 of the bearing pin 21.
- the other end 21.2 of the bearing pin 21, which also protrudes from the clutch housing 22, is coupled via a driver cross pin 28 to a plate-shaped rocker arm 29, the plate shape of which can best be seen from FIG. 1, which also shows a groove 30 of the rocker arm 29, in which engages the driving cross bolt 28.
- the rocker arm 29 coupled in its central part to the bearing pin 21 is provided at its lower end with a projecting web 31 with a semicircular cross section, which engages in a suitable manner in a bearing groove 32 formed on the clutch housing 22.
- Web 31 and bearing groove 32 form the pivot bearing point for the rocker arm 29, which is provided in the region of its other end with a profiled link surface 33 which interacts with the detent 34 of a release cam 35.
- the trigger cam 35 is mounted in the coupling housing 22 so as to be pivotable about an axis 36 and is not provided for reasons of clarity lever mechanism shown connected to a handle lever arranged below the chair seat in the grip area of a chair user.
- the link surface 33 is limited towards the free end of the rocker arm 29 by a stop web 33.1. This web is followed by a first latching surface 33.2, followed by an inclined sliding surface 33.3. The backdrop surface finally ends with a second locking surface 33.4.
- FIG. 1 and 2 show the release cam 35 in a position in which the multi-plate clutch is in frictional engagement of its plates 17, 20.
- the locking lug 34 of the release cam 35 is self-locking on the locking surface 33.4 of the rocker arm 29, which is pivoted clockwise around its bearing point 31/32 and has axially displaced the bearing pin 21 in the drawing to the right.
- the plate springs 26 have been pressed together and exert a clamping pressure on the plates 17, 20 of the multi-plate clutch 16 via the clamping plate 24.
- the latching cams 34 can be released from the latching surface 33.4 of the rocker arm 29 for releasing the multi-plate clutch, so that it moves along the link surface 33 of the rocker arm 29 under the tension of the plate springs 26 up to a system slides against the first locking surface 33.2 of the link surface 33 of the rocker arm 29.
- the bearing pin 21 can move back to the left in the drawing until the disc springs 26 relax and the frictional engagement of the lamellae is released.
Description
Die Erfindung betrifft einen Stuhl, insbesondere Bürostuhl, mit einer in ihrer Neigungslage zu einer Sitzfläche stufenlos verstellbaren und in eine ihrer Endstellungen vorgespannten Rückenlehne, die in ihren Neigungslagen durch eine Reibschluß-Lamellenkupplung gehalten ist, die mindestens eine auf die Lamellen einwirkende Spannfeder aufweist und die mittels eines unterhalb der Sitzfläche angeordneten Griffhebels betätigbar ist, wobei die mindestens eine Spannfeder konzentrisch auf einem axial verstellbaren, durch Schlitze in den Kupplungslamellen hindurchgeführten Lagerbolzen angeordnet ist, der ein Widerlager für die Spannfeder bildet.The invention relates to a chair, in particular office chair, with a backrest which is infinitely adjustable in its inclined position relative to a seat and pretensioned in one of its end positions, which is held in its inclined positions by a frictional multi-plate clutch which has at least one tension spring acting on the plates and which can be actuated by means of a handle lever arranged below the seat surface, the at least one tension spring being arranged concentrically on an axially adjustable bearing pin which is guided through slots in the clutch plates and forms an abutment for the tension spring.
Reibschluß-Lamellenkupplungen für die Rückenlehnen von Bürostühlen sind bereits in verschiedenen Ausführungsformen bekannt. Bei den meisten vorbekannten Konstruktionen, beispielsweise nach der GB-PS 401 718, wird die Lamellenkupplung vom Stuhlbenutzer mittels einer Schraubmutter betätigt, mit dem Nachteil, daß die Stärke des Reibschlusses von der Drehstellung einer Spannmutter und damit letztlich von der Kraft einer Bedienungsperson abhängt. Eine Konstruktion mit den vorstehend genannten Merkmalen und mit einem von der Kraft eines Stuhlbenutzers unabhängigen Reibschluß der Lamellenkupplung ist durch die DE-PS 29 27 377 bekannt. Diese Konstruktion berücksichtigt jedoch nicht die bei modernen Bürostühlen bestehende Forderung nach einem kompakten Aufbau und der Möglichkeit, daß ein Stuhlbenutzer mit der Rückenlehne frei wippen kann, ohne daß er dabei dauernd einen Hebel betätigen muß.Frictional multi-plate clutches for the backrests of office chairs are already known in various embodiments. In most known constructions, for example according to GB-PS 401 718, the multi-plate clutch is actuated by the chair user by means of a screw nut, with the disadvantage that the strength of the frictional connection depends on the rotational position of a clamping nut and thus ultimately on the force of an operator. A construction with the above features and with the power of a chair user independent frictional engagement of the multi-plate clutch is known from DE-PS 29 27 377. However, this construction does not take into account the existing requirement in modern office chairs for a compact structure and the possibility that a chair user can rock freely with the backrest without constantly having to operate a lever.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Stuhl mit den eingangs genannten Merkmalen einer Einrichtung zur Neigungsverstellung der Rückenlehne so auszubilden, daß die Verstelleinrichtung einen kompakten Aufbau mit wenig Einzelteilen bei wahlweiser Verriegelung oder Freigabe der Rückenlehne erlaubt.The invention is therefore based on the object of designing a chair with the features mentioned at the beginning of a device for tilting the backrest in such a way that the adjusting device allows a compact structure with few individual parts with optional locking or releasing the backrest.
Die gestellte Aufgabe wird mit der genannten Einrichtung erfindungsgemäß dadurch gelöst, daß der Griffhebel mit einem Auslösenocken verbunden ist, der auf ein mit dem axial verstellbaren Lagerbolzen gekoppeltes Kulissenteil einwirkt, das eine Rastausnehmung für den Auslösenocken mindestens in einer seiner Endstellungen aufweist. Vorteilhafterweise kann der mit dem Griffhebel verbundene Auslösenocken um eine feste Achse verschwenkbar sein und gegen eine profilierte Fläche des Kulissenteiles anliegen, das als mit dem axial verstellbaren Lagerbolzen in beiden Richtungen in Mitnahmeverbindung stehender, um eine feste Achse verschwenkbare Kipphebel ausgebildet sein kann.The stated object is achieved according to the invention by the fact that the handle lever is connected to a release cam which acts on a link part which is coupled to the axially adjustable bearing pin and which has a latching recess for the release cam at least in one of its end positions. Advantageously, the release cam connected to the handle lever can be pivotable about a fixed axis and can rest against a profiled surface of the link part, which can be designed as a driving connection with the axially adjustable bearing pin in both directions, pivotable about a fixed axis rocker arm.
Durch das Zusammenwirken eines Auslösenockens mit einem Kulissenteil, also einer insbesondere durch eine profilierte Fläche eines Kulissenteiles gebildeten Kurvenbahn wird bei dem erfindungsgemäß ausgebildeten Stuhl sowohl die Betätigung der Reibschluß-Lamellenkupplung als auch ihre Verriegelung in ihrer Freigabestellung oder ihrer Kupplungsstellung allein durch diese beiden Teile, den Auslösenocken und das Kulissenteil, ohne zusätzliche Sicherungsteile, erreicht. Dadurch wird ein raumsparender, kompakter Aufbau der Reibschluß-Lamellenkupplung und ihres Betätigungsteiles möglich.Due to the interaction of a release cam with a link part, i.e. a cam track formed in particular by a profiled surface of a link part, both the actuation of the friction multi-plate clutch and its locking in its release position or its clutch position are achieved solely by these two parts in the chair designed according to the invention Release cam and the link part, reached without additional safety parts. This results in a space-saving, compact design of the friction clutch and their actuating part possible.
Vorteilhafterweise kann der verschwenkbare Auslösenocken eine Rastnase aufweisen, die in beiden Endstellungen des Auslösenockens jeweils in eine Rastausnehmung der profilierten Anlagefläche des Kipphebels paßt, die zwischen ihren Rastausnehmungen eine schräge, zur Kippbewegung des Kipphebels führende Aufgleitfläche aufweist. Dabei läßt sich der Auslösenocken in seinen beiden Schwenkrichtungen immer in Anlage gegen den Kipphebel halten, der durch seine Mitnahmekoppelung mit dem Lagerbolzen der Einwirkung der Spannfeder - wenn auch mit wechselnder Federkraft - ausgesetzt bleibt. Dadurch kann das Schwenklager des Kipphebels auch als offenes Lager ausgebildet sein, zweckmäßig aus einer Lager-Halbschale bestehen, in welche der Kipphebel mit einem einen Teilkreisquerschnitt aufweisenden Lagervorsprung passend eingreift. Das nachträgliche Ausbilden von Lagerbohrungen und die Verwendung eines gesonderten Lagerbolzens können also entfallen. Die Konstruktion gemäß der Erfindung erlaubt eine Fertigung der wenigen Einzelteile in ihrer Endform, ganz oder weitgehend ohne eine Nachbearbeitung dieser Teile.Advantageously, the pivotable release cam can have a locking lug, which in both end positions of the release cam fits into a locking recess of the profiled contact surface of the rocker arm, which has an oblique sliding surface leading to the rocking movement of the rocker arm between its locking recesses. The trigger cam in its two pivoting directions can always be held against the rocker arm, which remains exposed to the action of the tension spring due to its driving coupling with the bearing pin - albeit with changing spring force. As a result, the pivot bearing of the rocker arm can also be designed as an open bearing, expediently consist of a bearing half-shell, in which the rocker arm engages appropriately with a bearing projection having a partial circular cross section. The subsequent formation of bearing bores and the use of a separate bearing pin can therefore be omitted. The construction according to the invention allows the few individual parts to be produced in their final shape, completely or largely without post-processing of these parts.

Fig. 1 zeigt von einem Stuhlgestell einen Teil einer Sitzträgerplatte 10 und eine mit der Sitzträgerplatte verbundene vertikale Lagerplatte 11 sowie eine horizontale Montageplatte 12 des Sitzträgerteiles des Stuhlgestelles. Außerdem ist von einem Rückenlehnenträger ein Tragarm 13 ersichtlich, dem bei der dargestellten Konstruktion ein zweiter, gleicher, parallel mit Abstand von ihm verlaufender, nicht dargestellter Tragarm beigeordnet ist. Beide Tragarme sind um eine in der Lagerplatte 11 angeordnete Schwenkachse 14 um einen begrenzten, an einem Langloch 15 der Lagerplatte 11 ersichtlichen Winkelbereich verschwenkbar und in diesem Verschwenkbereich stufenlos feststellbar gelagert. Die Fixierung der Neigungslage der Tragarme 13 des Rückenlehnenträgers gegenüber der Lagerplatte 11 wird mittels einer allgemein mit der Bezugsziffer 16 bezeichneten Reibschluß-Lamellenkupplung bewirkt, deren erfindungswesentliche Teile nachfolgend in Verbindung mit den Schnittbildern der Fig. 2 und 3 beschrieben werden. Fig. 1 zeigt, daß lange Lamellen 17 der Lamellenkupplung ebenfalls auf der Schwenkachse 14 für die Tragarme 13 gelagert sind und mit ihren aus der Kupplung 16 herausragenden Enden durch eine Stange 18 miteinander verbunden sind, die durch das bereits erwähnte, die Neigungsverstellung begrenzende Langloch 15 in der Lagerplatte 11 hindurchragt. An der Stange 18 greift eine auf die Schwenkachse 14 aufgeschobene Schraubentorsionsfeder 19 mit ihrem einen Federende 19.1 an. Das andere Federende 19.2 ist auf der Montageplatte 12 abgestützt. Die Schraubentorsionsfeder 19 bewirkt über die Stange 18 eine Vorspannung der Tragarme 13 in eine vordere Endstellung des Rückenlehnenträgers mit seinen Tragarmen 13, die in Fig. 1 dargestellt ist.Fig. 1 shows part of a chair frame of a
Wie die Schnittbilder der Fig. 2 und 3 zeigen, sind die langen Lamellen 17 mit nicht dargestellten großen Öffnungen 17.1 unter bekannter Zwischenlage von kurzen Lamellen 20 über einen Lagerbolzen 21 geschoben, der in einem auf der Montageplatte 12 befestigten Kupplungsgehäuse 22 axial verschiebbar gelagert ist. Das Lamellenpaket 17/20 der Lamellenkupplung liegt einerseits an einer festen Wandung 23 des Kupplungsgehäuses 22 an und wird anderseits durch eine ebenfalls auf den Lagerbolzen 21 aufgeschobene Druckscheibe 24 begrenzt, die gleichzeitig in einer Lageröffnung 25 des Lagergehäuses 22 geführt ist. An die Außenseite der Druckscheibe 24 schließen sich Tellerfedern 26 an - hier vier Tellerfedern - die ebenfalls auf den Lagerbolzen 21 aufgeschoben sind und deren anderes Widerlager durch eine verspannbare Schraubmutter 27 gebildet ist, die auf ein Gewindeende 21.1 des Lagerbolzens 21 aufgeschraubt ist.As the sectional views of FIGS. 2 and 3 show, the
Das andere, ebenfalls aus dem Kupplungsgehäuse 22 hinausragende Ende 21.2 des Lagerbolzens 21 ist über einen Mitnehmer-Querbolzen 28 mit einem plattenförmigen Kipphebel 29 gekoppelt, dessen Plattenform am besten aus Fig. 1 ersichtlich ist, die auch eine Nut 30 des Kipphebels 29 zeigt, in welche der Mitnahme-Querbolzen 28 eingreift. Der in seinem Mittelteil mit dem Lagerbolzen 21 gekoppelte Kipphebel 29 ist an seinem unteren Ende mit einem vorspringenden Steg 31 mit halbkreisförmigem Querschnitt versehen, der in eine an dem Kupplungsgehäuse 22 ausgebildete Lagernut 32 passend eingreift. Steg 31 und Lagernut 32 bilden die Schwenklagerstelle für den Kipphebel 29, der im Bereich seines anderen Endes mit einer profilierten Kulissenfläche 33 versehen ist, die mit der Rastnase 34 eines Auslösenockens 35 zusammenwirkt. Der Auslösenocken 35 ist in dem Kupplungsgehäuse 22 um eine Achse 36 verschwenkbar gelagert und ist über einen aus Übersichtlichkeitsgründen nicht dargestellten Hebelmechanismus mit einem unterhalb des Stuhlsitzes im Griffbereich eines Stuhlbenutzers angeordneten Griffhebel verbunden.The other end 21.2 of the
Die Kulissenfläche 33 ist zum freien Ende des Kipphebels 29 hin durch einen Anschlagsteg 33.1 begrenzt. An diesen Steg schließt sich eine erste Rastfläche 33.2 an, auf welche eine schräge Aufgleitfläche 33.3 folgt. Die Kulissenfläche endet schließlich mit einer zweiten Rastfläche 33.4.The
Die Fig. 1 und 2 zeigen den Auslösenocken 35 in einer Stellung, in welcher die Lamellenkupplung im Reibschluß ihrer Lamellen 17, 20 steht. Die Rastnase 34 des Auslösenockens 35 liegt dabei selbsthemmend an der Rastfläche 33.4 des Kipphebels 29, der im Uhrzeigersinne um seine Lagerstelle 31/32 verschwenkt ist und dabei den Lagerbolzen 21 in der Zeichnung nach rechts axialverschoben hat. Dadurch sind die Tellerfedern 26 zusammengepreßt worden und üben über die Spannplatte 24 einen den Reibschluß bewirkenden Spanndruck auf die Lamellen 17, 20 der Lamellenkupplung 16 aus.1 and 2 show the
Durch Kraftanwendung auf den nicht dargestellten und mit dem Auslösenocken 35 verbundenen Griffhebel läßt sich zum Lösen der Lamellenkupplung der Rastnocken 34 von der Rastfläche 33.4 des Kipphebels 29 lösen, so daß er entlang der Kulissenfläche 33 des unter der Spannung der Tellerfedern 26 stehenden Kipphebels 29 bis in eine Anlage gegen die erste Rastfläche 33.2 der Kulissenfläche 33 des Kipphebels 29 gleitet. Hierbei kann sich der Lagerbolzen 21 bis zu einer Entspannung der Tellerfedern 26 und dadurch dem Lösen des Reibschlusses der Lamellen in der Zeichnung nach links zurückbewegen.By applying force to the handle lever, not shown and connected to the
