Description

Die Erfindung betrifft eine Armlehne, insbesondere für einen Bürostuhl, mit einer vorzugsweise höhenverstellbaren Armlehnensäule und einer auf der Armlehnensäule gelagerten Armauflage.The invention relates to an armrest, in particular for an office chair, with a preferably height-adjustable armrest column and a mounted on the armrest armrest.

Eine derartige Armlehne ist aus der deutschen Patentanmeldung DE 101 25 996 A1 der Anmelderin bekannt. Bei der dort beschriebenen Armlehne ist eine Dreh- und Längsverstellung möglich. Weitere Armlehnen mit mehreren Einstellmöglichkeiten sind aus EP 1 424 029 A1 und US 6,290,300 B1 bekannt. Bauartbedingt sind die Einstellmöglichkeiten allerdings stets begrenzt. Insbesondere dann, wenn eine enge Armlehnengrundstellung vorgesehen ist, beispielsweise der Sitz breiter ist als das Innenmaß der Armauflagen, stoßen die individuellen Einstellmöglichkeiten der dort beschriebenen Armlehnen jedoch an ihre Grenzen. Es mangelt daher an einer vielfach einstellbaren Armlehne mit hoher Variabilität.Such armrest is from the German patent application DE 101 25 996 A1 the applicant known. In the armrest described there, a rotational and longitudinal adjustment is possible. Other armrests with multiple adjustment options are off EP 1 424 029 A1 and US 6,290,300 B1 known. Due to the design, however, the setting options are always limited. In particular, when a narrow armrest basic position is provided, for example, the seat is wider than the inner dimension of the armrests, however, the individual adjustment possibilities of the armrests described there are reaching their limits. There is therefore a lack of a multi-adjustable armrest with high variability.

US 2004/0066080-A offenbart eine Armlehne die um 360 Grad verdrehbar ist mit einer Linear-Schiebefürung US 2004/0066080-A discloses an armrest which is rotatable 360 degrees with a linear sliding guide

Eine Aufgabe der vorliegenden Erfindung ist es daher, eine multifunktionale Armlehne mit verbesserter Handhabung bereitzustellen. Diese Aufgabe wird durch eine Armlehne nach Anspruch 1 gelöst.An object of the present invention is therefore to provide a multifunctional armrest with improved handling. This object is achieved by an armrest according to claim 1.

Danach ist ein an der Armlehnensäule angeordneter Multifunktions-Lagerkopf vorgesehen, der eine Dreh-, Längs- und Querverstellmechanik aufweist. Zusätzlich zu der an sich bekannten Dreh- und Längsverstellung ist erfindungsgemäß auch eine Querverstellung der Armauflage möglich. Diese Armlehne gewährleistet somit eine konstruktiv einfache, leicht montierbare und dennoch zuverlässige Dreh-, Längs- und Querverstellung.Thereafter, a arranged on the armrest multi-functional bearing head is provided which has a rotary, longitudinal and Querverstellmechanik. In addition to the known rotation and longitudinal adjustment according to the invention, a transverse adjustment of the armrest is possible. This armrest thus ensures a structurally simple, easy mountable yet reliable rotary, longitudinal and transverse adjustment.

Insbesondere weist die Querverstellmechanik ein ortsfestes Plattformteil auf, welches mit einem zu dem Plattformteil quer beweglichen Tragelement zusammenwirkt.In particular, the transverse adjustment mechanism has a stationary platform part which cooperates with a support element which is transversely movable relative to the platform part.

Der Multifunktions-Lagerkopf ist in verschiedenen Funktionsebenen aufgebaut derart, daß eine untere Funktionsebene jeweils die darüberliegenden Funktionsebenen trägt. Dabei trägt das Tragelement der Querverstellmechanik die gesamte Längsverstellmechanik, während die Drehverstellmechanik wiederum von der Längsverstellmechanik getragen, beziehungsweise in diese integriert ist.The multi-functional bearing head is constructed in different functional levels such that a lower functional level carries each of the overlying functional levels. In this case, the support element of the Querverstellmechanik wears the entire Längsverstellmechanik, while the Drehverstellmechanik in turn carried by the Längsverstellmechanik, or is integrated into this.

Die Längsverstellmechanik weist eine Linear-Schiebeführung auf. Dabei ist diese vorzugsweise derart ausgeführt, daß sie einen Längsführungsrahmen umfaßt, in dem ein Lagerblock einliegt. Dieser Lagerblock trägt wiederum die Drehverstellmechanik, über welche die Armauflage mit dem Multifunktions-Lagerkopf verbunden ist.The longitudinal adjustment mechanism has a linear sliding guide. In this case, this is preferably designed such that it comprises a longitudinal guide frame in which a bearing block rests. This bearing block in turn carries the Drehverstellmechanik, via which the armrest is connected to the multi-functional bearing head.

Die Drehverstellmechanik ermöglicht eine Drehung der Armauflage um 360 Grad, so daß eine besonders flexible Verstellung der Armauflage möglich ist. Dies gilt insbesondere dann, wenn die Armauflage asymmetrisch geformt ist derart, daß ihre Längsseiten unterschiedlich weit ausladen. Im Zusammenhang mit der Querverstellung der Armauflage wird dann durch die Möglichkeit einer vollständigen Drehung der Armauflage das Innenmaß zwischen den Armauflagen in einem besonders hohen Maße variabel einstellbar.The Drehverstellmechanik allows rotation of the armrest by 360 degrees, so that a particularly flexible adjustment of the armrest is possible. This is especially true when the armrest is asymmetrically shaped such that their longitudinal sides unload differently. In connection with the transverse adjustment of the armrest, the inner dimension between the armrests is then variably adjustable to a particularly high degree by the possibility of complete rotation of the armrest.

Vorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Vorzugsweise sind die genannten Verstellmechaniken gerastert, und sind daher besonders einfach zu bedienen, und/oder kommen ohne Auslösetaste aus. Die Position der Armauflage kann mit anderen Worten geändert werden, ohne daß eine Auslösetaste betätigt werden muß. Die Bedienung der Armlehne ist daher besonders bedienungsfreundlich. Zur Ausführung eines ohne Auslösetaste betätigbaren Rastmechanismus weisen Plattformteil und Tragelement zusammenwirkende Rastelemente auf.Preferably, said adjustment mechanisms are screened, and are therefore particularly easy to use, and / or get by without a release button. The position of the armrest can be changed in other words, without a trigger button must be pressed. The operation of the armrest is therefore particularly easy to use. For executing an actuatable without a trigger button latching mechanism platform part and support member cooperating locking elements.

In einer weiteren Ausführungsform der Erfindung ist die Armauflage in ihrer Normalposition durch ein Verriegelungselement feststellbar. Dies wird vorzugsweise dadurch erreicht, daß ein Verdrehen der Armauflage nur nach einer Entriegelung durch Betätigung eines Tasters möglich ist. Somit wird sichergestellt, daß die Armlehne stets derart nach vorn weist, daß dem Nutzer eine bequeme Auflagehaltung möglich ist.In a further embodiment of the invention, the armrest is lockable in its normal position by a locking element. This is preferably achieved in that a rotation of the armrest is possible only after unlocking by pressing a button. This ensures that the armrest always points forward so that the user a comfortable support posture is possible.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels näher beschrieben, das mit Hilfe der Zeichnungen erläutert wird. Hierbei zeigt:

Die Armlehne 1 umfaßt eine höhenverstellbare, insbesondere teleskopartig aufgebaute Armlehnensäule 2, an deren oberen Ende ein Multifunktions-Lagerkopf 3 angeordnet ist. Dieser trägt eine Armauflage 4, die um eine vertikale Drehachse 5 drehbar und sowohl in Längsrichtung 6, als auch in Querrichtung 7 verschiebbar auf dem Lagerkopf 3 gehalten ist.The armrest 1 comprises a height-adjustable, in particular telescopically constructed armrest column 2, at the upper end of a multi-functional bearing head 3 is arranged. This carries an armrest 4 which is rotatable about a vertical axis of rotation 5 and held both in the longitudinal direction 6, and in the transverse direction 7 slidably on the bearing head 3.

Der Vertikalschenkel der Armlehnensäule 2 ist als Führungsständer ausgebildet, auf dem die Außenhülse 8 der Armlehnensäule 2 in Vertikalrichtung 9 verschiebbar geführt ist. Im Führungsständer ist eine Höhenverstell-Arretierung eingebaut (nicht abgebildet). Ein an dem Vertikalschenkel der Armlehnensäule 2 angeformter Horizontalschenkel (nicht abgebildet) dient zur Befestigung der Armlehne 1 am Unterbau eines Bürostuhles oder dergleichen.The vertical leg of the armrest column 2 is designed as a guide stand on which the outer sleeve 8 of the armrest column 2 is guided in the vertical direction 9 slidably. The guide stand has a height adjustment lock (not shown). An integrally formed on the vertical leg of the armrest column 2 horizontal leg (not shown) is used to attach the armrest 1 on the base of an office chair or the like.

Am oberen Ende der Armlehnensäule 2 ist die Außenhülse 8 gegenüber dem eigentlichen Säulenteil nach außen erweitert und bildet so die Basis 10 für den Multifunktions-Lagerkopf 3. Diese Basis 10 ist nach oben offen, wobei die Öffnung 11 durch eine deckelartige Grundplatte 12 des Multifunktions-Lagerkopfes 3 verschlossen ist. Die aus einem Kunststoffmaterial gefertigte Grundplatte 12 ist über eine Anzahl Fixierschrauben 13 mit der Armlehnensäule 2 verschraubt.At the upper end of the armrest column 2, the outer sleeve 8 is widened outwards relative to the actual column part and thus forms the base 10 for the multi-functional bearing head 3. This base 10 is open at the top, wherein the opening 11 through a cover-like base plate 12 of the multi-functional Bearing head 3 is closed. The made of a plastic material base plate 12 is over a Number of fixing screws 13 bolted to the armrest column 2.

Für die Höhenverstellung der Armlehne 1 ist ein Betätigungshebel vorgesehen, dessen Betätigungsende (nicht abgebildet) durch ein zur Außenseite der Basis 10 hin offenen Durchbruch 14 ragt. Ein möglicher Aufbau der Mechanik zur Höhenverstellung kann der Druckschrift DE 101 25 996 A1 entnommen werden. Jedoch sind grundsätzlich auch andere Techniken zur Höhenverstellung anwendbar.For the height adjustment of the armrest 1, an actuating lever is provided, the actuating end (not shown) protrudes through an open towards the outside of the base 10 opening 14. A possible structure of the mechanism for height adjustment can the document DE 101 25 996 A1 be removed. However, other techniques for height adjustment are basically applicable.

Auf der Grundplatte 12 ist eine Querverstellmechanik 16 angeordnet, welche im wesentlichen aus einem Plattformteil in Form einer Rastplatte 17 und einem darauf in Querrichtung 7 beweglich befestigten Tragelement 18 besteht. Das Tragelement 18 weist drei voneinander beabstandete, in Dreiecksform versetzt zueinander angeordnete und in Querrichtung 7 verlaufende Führungskanäle 19 auf. Jedem dieser Führungskanäle 19 ist ein bolzenförmiges Befestigungsglied 20 zugeordnet. Dabei ist jedes Befestigungsglied 20 mit einem ringförmigen Gleitelement 21 versehen und derart in dem Führungskanal 19 festgelegt, daß es die Rastplatte 17 an der Grundplatte 12 des Multifunktions-Lagerkopfes 3 fixiert und gleichzeitig eine Querverstellung des Tragelementes 18 ermöglicht. Die Gleitelemente 21 liegen in der Montageendposition an dem Kragen des Befestigungsgliedes 20 an und stützen sich an den in den Innenseiten der Führungskanäle 19 umlaufend angeordneten Führungsnuten 15 ab. Die Befestigungsglieder 20 führen durch die Führungskanäle 19 und entsprechenden Aufnahmebohrungen 22 in der Rastplatte 17 hindurch und wirken mit Schraubgewinden zusammen, die in drei Stützelementen 23 vorgesehen sind, welche sich zur Abstützung der Rastplatte 17 domförmig aus der Grundplatte 12 nach oben erstrecken.On the base plate 12 a Querverstellmechanik 16 is arranged, which consists essentially of a platform part in the form of a detent plate 17 and a movable in the transverse direction 7 support member 18. The support element 18 has three guide channels 19, which are spaced apart from one another and offset in a triangular manner and extend in the transverse direction 7. Each of these guide channels 19 is associated with a bolt-shaped attachment member 20. In this case, each fastening member 20 is provided with an annular sliding member 21 and fixed in the guide channel 19, that it fixes the locking plate 17 on the base plate 12 of the multi-functional bearing head 3 while allowing transverse adjustment of the support member 18. The sliding elements 21 are in the final assembly position on the collar of the fastening member 20 and are based on the in the inner sides of the guide channels 19 circumferentially arranged guide grooves 15 from. The fastening members 20 pass through the guide channels 19 and corresponding receiving bores 22 in the detent plate 17 and cooperate with screw threads which are provided in three support elements 23, which are for support the detent plate 17 extend dome-shaped from the base plate 12 upwards.

In der dem Tragelement 18 zugewandten Oberseite 24 der Rastplatte 17 sind in einer Vertiefung 25 eine Anzahl von in Querrichtung 7 hintereinander angeordneten Raststufen 26 ausgebildet. Zwischen Rastplatte 17 und Tragelement 18 ist ein walzenförmiges Rastsperrelement 27 vorgesehen, welches von einem Federelement in Form eines Elastomerblocks 28 beaufschlagt wird und mit den Raststufen 26 zusammenwirkt. Der Elastomerblock 28 liegt dabei in einer entsprechenden Aufnahme 29 an der Unterseite 31 des Tragelements 18 ein. Mit anderen Worten wird durch eine Querverstellung des Tragelements 18 das Rastsperrelement 26 ohne Betätigung eines Auslösetasters oder dergleichen gegen den Widerstand und unter Verformung des Elastomerblocks 28 von einer Raststufe 26 zur nächsten bewegt. Vorzugsweise sind dabei die Raststufen 26 beidseitig mit identischen Anlaufschrägen versehen, so daß so sowohl die Hin- als auch die Rückbewegung mit einem gleichen Kraftaufwand bewältigt werden kann.In the support element 18 facing upper side 24 of the detent plate 17 a number of transversely arranged in the transverse direction 7 latching steps 26 are formed in a recess 25. Between detent plate 17 and support member 18, a roller-shaped detent locking element 27 is provided, which is acted upon by a spring element in the form of an elastomeric block 28 and cooperates with the latching steps 26. The elastomer block 28 lies in a corresponding receptacle 29 on the underside 31 of the support element 18 a. In other words, the latching element 26 is moved by a transverse displacement of the support member 18 without actuation of a trigger button or the like against the resistance and with deformation of the elastomeric block 28 from one latching step 26 to the next. Preferably, the latching steps 26 are provided on both sides with identical run-on slopes, so that both the outward and the return movement can be handled with the same effort.

Die Rastplatte 17 ist vorzugsweise aus einem Kunststoffmaterial hergestellt, wobei die Raststufen 26 während des Herstellungsprozesses als integraler Bestandteil der Rastplatte 17 ausgebildet werden.The latching plate 17 is preferably made of a plastic material, wherein the latching steps 26 are formed during the manufacturing process as an integral part of the locking plate 17.

Das vorzugsweise aus Aluminium bestehenden Tragelement 18 weist an seiner Oberseite 32 einen Befestigungsdom 33 mit innenliegendem Schraubgewinde auf. Dieser dient zur Befestigung einer Dreh- und Längsverstellmechanik auf der Querverstellmechanik 16 in noch näher zu erläuternder Weise. Direkt auf dem Tragelement 18 ist ein Längsführungsrahmen 34 einer Längsverstellmechanik 35 angeordnet, der zugleich als Träger für ein Grundelement 36 der Armauflage 4 dient. In dem im wesentlichen über die gesamte Länge des Längsführungsrahmens 34 verlaufenden Führungskanal 37 liegt ein Lagerblock 38 für eine Drehverstellmechanik 39 ein. Die Längsführung des Lagerblocks 38 erfolgt dabei durch in Längsrichtung 6 verlaufende Führungsflanken 40 zu beiden Seiten des Längsführungsrahmens 34 und entsprechende Gegenführungsflanken 41 am Lagerblock 38.The support element 18, which is preferably made of aluminum, has on its upper side 32 a fastening dome 33 with an internal screw thread. This is used to attach a rotary and Längsverstellmechanik on the Querverstellmechanik 16 in a manner to be explained in more detail. Directly on the support element 18, a longitudinal guide frame 34 of a Längsverstellmechanik 35 is arranged, which also serves as a support for a base member 36 of the armrest 4. In the substantially over the entire length of the longitudinal guide frame 34 extending guide channel 37 is a bearing block 38 for a Drehverstellmechanik 39 a. The longitudinal guide of the bearing block 38 is effected by extending in the longitudinal direction 6 guide flanks 40 on both sides of the longitudinal guide frame 34 and corresponding counter-leading edges 41 on the bearing block 38th

Für einen Spielausgleich in Querrichtung 7 sind an der Lagerblockunterseite 42 zwei Federelement-Paare aus einem elastischen Material, beispielsweise Gummi, vorgesehen. Beispielhaft ist eines der Federelement-Paare 30, 30' abgebildet. Die einzelnen Federelemente, die im unmontierten Zustand einen kreisrunden Querschnitt aufweisen, liegen in ovalen Aufnahmen 43 des Lagerblocks 38 unter Spannung ein. Dabei liegen sie mit ihren äußeren Mantelflächen an Rastvertiefungen 44 an, die in den Führungsflanken 40 des Längsführungsrahmens 34 angeordnet sind, und sich im wesentlichen über die gesamte Länge des Führungskanals 37 erstrecken. Im montierten Zustand sind die langen Halbachsen der Aufnahmen 43 größer und die kurzen Halbachsen der Aufnahmen 43 kleiner als die Außendurchmesser der Federelemente. Der Abstand der Rastvertiefungen 44 zueinander ist dabei so gewählt, daß stets alle vier Federelemente in Rastvertiefungen 44 einliegen.For a clearance compensation in the transverse direction 7, two spring element pairs of an elastic material, such as rubber, are provided on the bearing block lower side 42. By way of example, one of the spring element pairs 30, 30 'is shown. The individual spring elements, which have a circular cross-section in the unmounted state, are in oval receptacles 43 of the bearing block 38 under tension. They rest with their outer lateral surfaces on latching depressions 44, which are arranged in the guide flanks 40 of the longitudinal guide frame 34, and extend substantially over the entire length of the guide channel 37. In the assembled state, the long half-axes of the receptacles 43 are larger and the short half-axes of the receptacles 43 smaller than the outer diameter of the spring elements. The distance between the locking recesses 44 to each other is chosen so that always all four spring elements einliegen in locking recesses 44.

Die Federelemente sind nach Art eines kurzen Rohrstückes ausgebildet und weisen identische Innendurchmesser auf. Die beiden Federelemente 30, 30' eines Federelementpaares sind mit ihren Öffnungen auf Haltezylindern 46, 46' mit kreisrunden Querschnitten aufgesteckt. Dabei ist jeweils dem einen Federelement 30 eines Federelementpaares ein Haltezylinder 46 mit einem Querschnitt zugeordnet, der dem Innendurchmesser des Federelements entspricht, während dem anderen Federelement 30' des Federelementpaares ein Haltezylinder 46' mit einem deutlich geringeren Querschnitt zugeordnet ist. Hierdurch wird erreicht, daß bei einem Verfahren des Lagerblocks 38 in Längsrichtung 7 das dem Haltezylinder 46' mit dem geringeren Durchmesser zugeordnete Federelement 30' verformt wird, während das zugehörige zweite Federelement 30 nahezu unverformt bleibt. In Schieberichtung 7 wechseln sich dabei Haltezylinder 46, 46' mit verschiedenen Durchmessern ab. Somit ist ein Anliegen der Federelemente 30, 30' an den Führungsflanken 40 und damit zugleich ein Spielausgleich jederzeit gewährleistet. Darüber hinaus dienen die walzenförmigen Federelemente 30, 30' im Zusammenspiel mit den Rastvertiefungen 44 zur Ausbildung einer auslösetastenfreien, gerasterten Verstellmechanik, die aufgrund der gleichbleibenden Ausgestaltung der Rastvertiefungen 44 sowohl bei Hin- als auch bei Rückbewegungen des Lagerblocks 38 den gleichen Kraftaufwand erfordern.The spring elements are designed in the manner of a short piece of pipe and have identical inner diameter. The two spring elements 30, 30 'of a spring element pair are with their openings on retaining cylinders 46, 46' with circular cross sections attached. In this case, each one spring element 30 of a spring element pair is associated with a holding cylinder 46 having a cross section corresponding to the inner diameter of the spring element, while the other spring element 30 'of the spring element pair is associated with a holding cylinder 46' with a significantly smaller cross-section. This ensures that in a process of the bearing block 38 in the longitudinal direction 7, the holding cylinder 46 'associated with the smaller diameter spring element 30' is deformed, while the associated second spring element 30 remains almost undeformed. In the sliding direction 7, while retaining cylinder 46, 46 'alternate with different diameters. Thus, a concern of the spring elements 30, 30 'on the guide flanks 40 and thus at the same time a clearance compensation guaranteed at any time. In addition, the roller-shaped spring elements 30, 30 'in cooperation with the detent recesses 44 serve to form a trigger button-free, screened adjustment mechanism, which require the same effort due to the constant configuration of the detent recesses 44 both in Hin- and during return movements of the bearing block 38.

Der Lagerblock 38 weist mittig eine im wesentlichen kreisrunde Aufnahmeausnehmung 47 auf, in der ein Rastmechanismus der Drehverstellmechanik 39 einliegt. Hierzu ist eine kreisförmige Rastscheibe 48 vorgesehen, welche an ihrer Unterseite 49 mit radial angeordneten Raststufen 50 versehen ist und zumindest teilweise in der Aufnahmeausnehmung 47 des Lagerblocks 38 einliegt. Zur Ausbildung der Drehrasterung weist die Aufnahmeausnehmung 47 zwei sich gegenüberliegende, in Lagerblocklängsrichtung verlaufende und in der Mitte des Lagerblocks 38 verlaufende Vertiefungen 51 auf, die zur Aufnahme von Rastelementen in Form von Nutensteinen 52 dienen. Diese werden von Federelementen in Form von Elastomerblöcken 53 beaufschlagt, die jeweils hinter die Nutensteine 52 bei der Montage in die nach oben offenen Vertiefungen 51 eingelegt werden können.The bearing block 38 has centrally a substantially circular receiving recess 47, in which a latching mechanism of the Drehverstellmechanik 39 rests. For this purpose, a circular detent disk 48 is provided, which is provided on its underside 49 with radially arranged latching steps 50 and at least partially rests in the receiving recess 47 of the bearing block 38. To form the rotary indexing, the receiving recess 47 has two opposite, running in the bearing block longitudinal direction and extending in the middle of the bearing block 38 Recesses 51, which serve to receive locking elements in the form of sliding blocks 52. These are acted upon by spring elements in the form of elastomer blocks 53, which can be inserted in each case behind the sliding blocks 52 during assembly in the upwardly open recesses 51.

Die Rastscheibe 48 weist eine zentrale Bohrung 54 auf, die an der Unterseite 49 der Rastscheibe 48 in im Wesentlichen quadratischer Form für ein Zusammenwirken mit dem Befestigungsdom 33 des Tragelements 18 ausgebildet ist. Der Befestigungsdom 33 weist hierfür in seinem für die Einsetzen in die Bohrung 54 ausgebildeten oberen Teil einen im Wesentlichen quadratischen Querschnitt auf. Die Bohrung 54 dient der Aufnahme einer Halteschraube 55, durch die Rastscheibe 48, Lagerblock 38 und Längsführungsrahmen 34 am Befestigungsdom 33 des Tragelements 18 fixiert werden. Hierzu weist die Aufnahmeausnehmung 47 des Lagerblocks 38 eine zentrale kreisrunde Öffnung 56 auf. Ebenso ist in der die Führungsflanken 40 des Längsführungsrahmens 34 verbindenden Abschlußplatte 57 der Längsverstellmechanik 35 zur Aufnahme des Befestigungsdomes 33 ein entsprechender Führungskanal 58 zur Verstellung in Längsrichtung 6 vorgesehen.The locking disc 48 has a central bore 54 which is formed on the underside 49 of the locking disc 48 in a substantially square shape for cooperation with the mounting dome 33 of the support member 18. For this purpose, the fastening dome 33 has a substantially square cross-section in its upper part designed for insertion into the bore 54. The bore 54 serves to receive a retaining screw 55, are fixed by the locking disc 48, bearing block 38 and longitudinal guide frame 34 on the mounting dome 33 of the support member 18. For this purpose, the receiving recess 47 of the bearing block 38 has a central circular opening 56. Likewise, in the guide flanks 40 of the longitudinal guide frame 34 connecting end plate 57 of the Längsverstellmechanik 35 for receiving the fixing dome 33, a corresponding guide channel 58 for adjustment in the longitudinal direction 6 is provided.

Das Grundelement 36 der Armauflage 4 ist mit dem Längsführungsrahmen 34 der Längsverstellmechanik 35 über Schraubverbindungen 59 verbunden. Damit der Lagerblock 38 in dem Längsführungsrahmen 34 möglichst weit in Längsrichtung 6 verfahrbar ist, sind an den Querseiten 60 des Lagerblocks 38 Ausnehmungen 61 für die Schraubverbindungen 59 vorgesehen.The base member 36 of the armrest 4 is connected to the longitudinal guide frame 34 of the Längsverstellmechanik 35 via screw 59. So that the bearing block 38 in the longitudinal guide frame 34 as far as possible in the longitudinal direction 6 can be moved, 38 recesses 61 are provided for the screw 59 on the transverse sides 60 of the bearing block.

Auf das Grundelement 36 ist das Armauflagepolster 61 unter Ausbildung einer Schnapp- bzw. Rastverbindung 62 befestigt.On the base member 36, the Armauflagepolster 61 is attached to form a snap or locking connection 62.

Zum Längs- und/oder Querverschieben der Armauflage 4 am Multifunktions-Lagerkopf 3 muß lediglich die Armauflage 4 gegriffen und entsprechend verschoben werden. Da keinerlei Auslösetasten für die Längs- und Querverstellung vorgesehen sind, ist dies mit einem bedienungstechnischen Minimalaufwand zu bewerkstelligen.For longitudinal and / or transverse displacement of the armrest 4 on the multi-function bearing head 3, only the armrest 4 must be grasped and moved accordingly. Since no release buttons are provided for the longitudinal and transverse adjustment, this can be done with a minimum technical effort.

Da die Armauflage 4 asymmetrisch geformt ist derart, daß die Längsseiten 63, 63' unterschiedlich weit in Querrichtung 7 ausladen, kann durch Drehung der Armauflage 4 um 180° ein besonders variables Innenmaß zwischen den Armauflagen 4 ermöglicht.Since the armrest 4 is asymmetrically shaped such that the longitudinal sides 63, 63 'unload differently wide in the transverse direction 7, a particularly variable internal dimension between the armrests 4 can be made possible by rotation of the armrest 4 through 180 °.

Der erfindungsgemäße Multifunktions-Lagerkopf 3 kann zusammen mit beliebigen Armlehnen 1 verwendet werden, insbesondere mit solchen Armlehnen, bei denen die Höhenverstellung in der Armlehnensäule 2 erfolgt. Selbstverständlich ist der Multifunktions-Lagerkopf 3 jedoch auch bei Armlehnen anwendbar, die über keine Höhenverstellung verfügen.The inventive multi-functional bearing head 3 can be used together with any armrests 1, in particular with such armrests, where the height adjustment in the armrest column 2 takes place. Of course, the multi-functional bearing head 3 but also applicable to armrests that have no height adjustment.

Zusätzlich verfügt die Armlehne 1 über eine Verriegelung in ihrer Normalposition. Hierzu ist zwischen dem Tragelement 18 und der Rastplatte 17 ein Taster 64 und eine Rastnase 65 vorgesehen, vgl. Fig. 1A und 2A sowie Fig. 5. Die Rastnase 65 ragt durch die Durchtrittsöffnung 70 durch das Tragelement 18 hindurch und ragt im verrasteten Zustand in eine der Rastausnehmungen 66 bzw. 67 an der Abschlußplatte 57 hinein. In ihren durch die Lage der Rastausnehmungen 66, 67 in etwa parallel zu dem Führungskanal 58 definierten Normalpositionen sind die Armauflagen 4 in etwa senkrecht zu der Rückenlehne des Bürostuhls (nicht abgebildet) angeordnet. Durch die Anordnung der Rastausnehmungen 66, 67 in der Abschlußplatte 57 kann die Normalposition selbstverständlich auch derart festgelegt werden, daß die Armauflagen 4 leicht schräg zueinander stehen, beispielsweise dergestalt, daß die Lage der Armauflagen 4 der Position der Unterarme eines Nutzers entsprechen, der eine Computertastatur bedient.In addition, the armrest 1 has a lock in its normal position. For this purpose, a button 64 and a latching lug 65 is provided between the support element 18 and the detent plate 17, cf. Fig. 1A and 2A such as Fig. 5 , The locking lug 65 protrudes through the passage opening 70 through the support element 18 and protrudes in the latched state into one of the recesses 66 and 67 on the end plate 57. In their by the position of the recesses 66, 67 approximately parallel to the guide channel 58 defined normal positions, the armrests 4 are arranged approximately perpendicular to the backrest of the office chair (not shown). By the arrangement of the recesses 66, 67 in the end plate 57, the normal position can of course also in such a way be determined that the armrests 4 are slightly inclined to each other, for example, such that the position of the armrests 4 correspond to the position of the forearms of a user who operates a computer keyboard.

Der vorzugsweise aus einem Kunststoffmaterial hergestellte Taster 64 umfaßt im einzelnen ein Tastelement 68 und ein an dem einen Ende des Tastelements 68 angeformten Auslenkfinger 69. An dem gegenüberliegenden Ende des Tastelements 68 ist dieses über eine Lagerstelle 72 am Tragelement 18 schwenkbar gelagert. Am Ende des Auslenkfingers 69 ist ein Keil 73 einteilig angeformt, insbesondere angespritzt. Bei einer Betätigung des Tasters 64 in Auslöserichtung 71 wird das Tastelement 68 um die Lagerstelle 72 herum gedreht derart, daß sich der Auslenkfinger 69 in Richtung der Rastnase 65 bewegt. Dabei drückt der Auslenkfinger 69 die Nase des Keils 73 in Auslöserichtung 71 in die Rastnase 65, die zu diesem Zweck eine der Keilform angepaßte und gleichfalls abgeschrägte Aufnahmeöffnung 74 aufweist. Durch das Einführen der Anlaufschräge 76 des Keils 73 in die Aufnahmeöffnung 74 wird die Rastnase 65 bei einer weiteren Betätigung des Tasters 64 linear aus der Rastausnehmung 66 bzw. 67 herausgeführt, vgl. Fig. 5. Die Armauflage 4 wird mit anderen Worten für eine Drehung freigegeben. Da die Verriegelung über ein lineares Ein- bzw. Ausfahren der Rastnase in Entriegelungsrichtung 77 erfolgt, vgl. Fig. 4, wird verhindert, daß bei einer Drehung der Armauflage 4 die Rastnase 65 aus der Rastausnehmung ausgetrieben wird.The probe 64 preferably made of a plastic material comprises in detail a probe element 68 and an integrally formed on the one end of the sensing element 68 Auslenkfinger 69. At the opposite end of the probe element 68 this is pivotally mounted via a bearing 72 on the support member 18. At the end of Auslenkfingers 69 a wedge 73 is integrally formed, in particular molded. Upon actuation of the button 64 in the release direction 71, the probe element 68 is rotated about the bearing 72 around so that the Auslenkfinger 69 moves in the direction of the latching lug 65. In this case, the Auslenkfinger 69 presses the nose of the wedge 73 in the release direction 71 in the locking lug 65, which has adapted for this purpose, a wedge shape adapted and also beveled receiving opening 74. By inserting the run-on slope 76 of the wedge 73 into the receiving opening 74, the latching lug 65 is led out linearly from the latching recess 66 or 67 during a further actuation of the pushbutton 64, cf. Fig. 5 , The armrest 4 is released in other words for rotation. Since the locking takes place via a linear retraction or extension of the locking lug in unlocking direction 77, cf. Fig. 4 , It is prevented that on a rotation of the armrest 4, the latching lug 65 is driven out of the recess.

Die Betätigung des Tastelements 68 sowie die Verschiebung der Rastnase 65 erfolgt gegen die Federkraft eines die Rastnase 65 gegen den Rand des Tragelements 18 abstützenden Federelementes 78, das ein unbeabsichtigtes Entriegeln verhindert.The actuation of the probe element 68 and the displacement of the latching lug 65 takes place against the spring force of the latching lug 65 against the edge of the support element 18 Spring element 78, which prevents unintentional unlocking.

Da die Rastausnehmungen 66, 67 auf beiden Seiten des Führungskanals 58 vorgesehen sind, ist eine Drehung der Armauflage 4 um 180 Grad bis zur nächsten Verriegelungsposition möglich. Zu beachten ist, daß durch die Ausbildung der Rastausnehmungen 66, 67 als Führungsnuten auch im verriegelten Zustand sichergestellt ist, daß sich die Armauflage 4 in Längsrichtung 6 bewegen läßt. Eine Bewegung in Querrichtung 7 ist selbstverständlich ebenfalls jederzeit möglich. Selbstverständlich liegt es im Rahmen der Erfindung, die beschriebene Verriegelung nicht zu verwenden. Dann liegt eine auslösetastenfreie Dreh-, Längs- und Querverstellmechanik 39, 35, 16 vor.Since the recesses 66, 67 are provided on both sides of the guide channel 58, a rotation of the armrest 4 by 180 degrees to the next locking position is possible. It should be noted that it is ensured by the formation of the recesses 66, 67 as guide even in the locked state that the armrest 4 can be moved in the longitudinal direction 6. A movement in the transverse direction 7 is of course also possible at any time. Of course, it is within the scope of the invention not to use the lock described. Then there is a release button-free rotary, longitudinal and Querverstellmechanik 39, 35, 16 before.

Unter Verwendung des erfinderischen Grundgedankens und der in der Beschreibung erläuterten Ausführungsform der Erfindung ergeben sich für einen Fachmann eine Vielzahl weiterer Ausführungsbeispiele, die jedoch an dieser Stelle nicht im einzelnen beschrieben werden können. Es wird darauf hingewiesen, daß alle in der Beschreibung, den Ansprüchen und den Zeichnungen dargestellten Merkmale sowohl einzeln als auch in beliebiger Kombination miteinander erfindungswesentlich sein können.Using the inventive concept and the embodiment of the invention explained in the description, a large number of further exemplary embodiments will be apparent to a person skilled in the art, which, however, can not be described in detail here. It should be noted that all features illustrated in the description, the claims and the drawings can be essential to the invention both individually and in any desired combination.
