Description

Die Erfindung betrifft eine Armstütze nach dem Oberbegriff des Anspruchs 1.The invention relates to an armrest according to the preamble of claim 1.

Aus der EP 1 258 209 ist ein Verstellmechanismus für ein gegenüber einem Gestell zu verstellendes Teil bekannt. Als Ausführungsbeispiel wird eine Armstütze beschrieben, die gegenüber dem Untergestell des Stuhles höhenverstellbar ist. Dazu wird ein Armstützenhalter mit dem Untergestell des Stuhles so verbunden, dass er (stuhl-)gestellfest angeordnet ist. Mit der Armauflage ist eine Führungshülse verbunden, die den Armstützenhalter übergreifend auf ihm verschieblich angeordnet ist. Zur schrittweisen Verstellung der Höhe der Armauflage ist eine Rastmechanik vorgesehen, die in dem Armstützenhalter mit der Armauflage verbunden ist. Dazu ist dieser Armstützenhalter zumindest teilweise als Rohr ausgebildet, in dessen Hohlraum die Rastmechanik eingesetzt wird. Diese wird von einer Verstellkartusche mit hohlem Innenraum und mit voneinander beabstandeten Rastöffnungen gebildet, die fest in den Armstützenhalter eingesetzt sind. Der Hohlraum dieser Verstellkartusche nimmt ein gegenüber der Verstellkartusche verschiebbares Verstellschwert auf, dessen Kopf mit der Armauflage verbunden ist, und in dem eine Auslösestange verschiebbar geführt ist. Diese Auslösestange weist an dem in das Verstellschwert eingeführten Ende ein Fenster mit einer Schrägführung auf, die als Führungskulisse für einen Sperrkörper dient, der seitlich überstehend mit seinen Überständen in dem Fenster geführt ist. Bei Betätigung dieser Auslösestange wird der Sperrkörper rechtwinklig zur Achse des Verstellschwertes so bewegt, dass seine Überstände in eine der korrespondierenden Rastöffnungen einführbar bzw. aus diesen heraus bewegbar ist. Dieser Aufbau einer Höhenverstellung einer Armstütze mit seiner Reihe von Einzelteilen ist äußert komplex aufgebaut und so nicht einfach und wirtschaftlich herstellbar.From EP 1 258 209 an adjusting mechanism for a relative to a frame to be adjusted part is known. As an exemplary embodiment, an armrest is described, which is height adjustable relative to the base of the chair. For this purpose, an armrest holder with the base of the chair is connected so that it is (chair) fixed to the frame. With the armrest, a guide sleeve is connected, which arranged the armrest holder across it slidably is. For stepwise adjustment of the height of the armrest a latching mechanism is provided, which is connected in the armrest holder with the armrest. For this purpose, this armrest holder is at least partially formed as a tube, in the cavity of the locking mechanism is used. This is formed by an adjustment cartridge with a hollow interior and with spaced-apart detent openings, which are firmly inserted into the armrest holder. The cavity of this adjustment takes on an adjustable displacement with respect to the adjustment Verstellschwert, whose head is connected to the armrest, and in which a trip bar is guided displaceably. This trigger bar has at the end inserted into the adjusting blade on a window with a slanted guide, which serves as a guide link for a locking body, which is guided laterally projecting with its projections in the window. Upon actuation of this trip bar, the locking body is moved at right angles to the axis of the adjusting sword so that its supernatants in one of the corresponding detent openings inserted or moved out of these. This structure of a height adjustment of an armrest with its series of items is extremely complex and so not easy and economical to produce.

Ein weiteres Beispiel ist aus dem Patentdokument US5439269 bekannt und betrifft eine Armstütze nach dem Oberbegriff des Anspruchs1.Another example is known from patent document US5439269 and relates to an armrest according to the preamble of claim 1.

Somit ergibt sich die Aufgabenstellung, eine gattungsgemäße Armstütze, die höhenverstellbar ist, vorzuschlagen, deren vereinfachter Aufbau wirtschaftlich herstellbar ist.Thus, the task, a generic armrest, which is adjustable in height, proposes to suggest the simplified structure is economical to produce.

Diese Aufgabenstellung wird durch die kennzeichnenden Merkmale des Hauptanspruchs gelöst: vorteilhafte Weiterbildungen und bevorzugte Ausführungsformen beschreiben die Unteransprüche.This problem is solved by the characterizing features of the main claim: advantageous developments and preferred embodiments describe the dependent claims.

Als Rastmittel ist in den Hohlraum des Armstützenhalters ein Rasteinschub eingesetzt, der im Wesentlichen die Form eines rechtwinkligspitzwinkligen Dreiecks aufweist. Seine dem rechten Winkel entsprechende Ecke ist mit seitlich überstehenden Achsstummeln versehen, die im Armstützenträgerkopf gelagert sind, so dass der Rasteinschub um diese Achse geschwenkt werden kann. Zum Auslösen der Schwenkbewegung ist dessen dem stumpferen der beiden restlichen Winkel zugeordnete Ecke als Auslöshebel ausgebildet und aus dem Armstützenträger-kopf so herausgeführt, dass eine Bedienung durch den Sitzenden einfach möglich ist, wenn dieser die Armauflage untergreift. Nahe der dritten Ecke weist der Rasteinschub eine Rastnase auf, die mit den Rastausnehmungen zusammenwirkt. An diese dritte Ecke des Rasteinsatzes ist eine Rückstellfeder angeformt, die sich an der Innenwandung abstützt, die den Rastausnehmungen gegenüberliegt. Mit dieser Anordnung gelingt es, die Rastmechanik mit dem in die Führungshülse einführbaren Rastmittel so auszubilden, dass nur ein Teil hergestellt und eingesetzt werden muss.As latching means a latch insert is inserted into the cavity of the armrest holder, which has substantially the shape of a right-angled triangle. Its corner, which corresponds to the right angle, is provided with laterally projecting stub axles, which are mounted in the arm support carrier head, so that the detent insert can be pivoted about this axis. To trigger the pivoting movement of the dull of the two remaining angles associated corner is designed as a trigger lever and from the armrest support head led out so that an operation by the sitter is easily possible when this engages under the armrest. Near the third corner of the latch insert on a locking lug, which cooperates with the recesses. At this third corner of the latching insert, a return spring is formed, which is supported on the inner wall, which is opposite to the recessed recesses. With this arrangement, it is possible to form the locking mechanism with the insertable into the guide sleeve locking means so that only a part must be made and used.

Dieser Rasteinsatz wird dabei mit einer Riegelplatte, die auf den Kopf des Armstützenträger aufgeschraubt wird, in seiner Position gehalten, wobei die Achsstummel in entsprechenden Ausnehmungen des Armstützenträgerkopf liegen. Diese Riegelplatte ist vorteilhaft so ausgebildet, dass sie mit der Halteschraubenaufnahme für eine der Halteschrauben versehen ist. So kann der Auslösehebel zentral in Flucht mit dem Rasteinsatz ausgebildet werden, der dann eine Ausformung derart aufweist, dass er unter der Riegelplatte durchgeführt werden kann.This locking insert is held in its position with a locking plate which is screwed onto the head of the armrest support, wherein the stub axle lie in corresponding recesses of the armrest support head. This latch plate is advantageously designed so that it is provided with the retaining screw receptacle for one of the retaining screws. Thus, the release lever can be centrally formed in alignment with the locking insert, which then has a shape such that it can be performed under the latch plate.

Die an das freie Ende des Rasteinsatzes angeformte Rückstellfeder ist U- oder V-förmig ausgebildet. Ihr vorteilhaft abgerundetes freies Ende bildet einen Kreisbogen, der auf der den Rastausnehmungen gegenüberliegenden Innenwandung des den Rasteinsatz aufnehmenden Schlitzes anliegt und beim Spannen bzw. Entspannen der Rückstellfeder "abrollen" kann.The formed on the free end of the locking insert return spring is U-shaped or V-shaped. Your advantageous rounded free end forms a circular arc, which rests on the opposite side of the recesses inner wall of the locking insert receiving slot and "unroll" when tensioning or relaxing the return spring.

Vorteilhaft wird der Rasteinsatz einstückig aus einem Kunststoff als Spritzgussteil geformt. Der Auslösehebel ist dabei ebenso angeformt, wie auch die Rückstellfeder. Diese Herstellung stellt eine wirtschaftliche Fertigung schon bei mittleren Stückzahlen sicher. Als Kunststoff wird vorteilhaft ein thermoplastischer Kunststoff hoher Festigkeit, etwa ein thermoplastisches Polykondensat, beispielsweise ein Polyamid oder Polycarbonat, ggf. noch mit Fasernverstärkung, oder ein Kunststoff hoher Elastizität, etwa ein thermoplastisches Polymerisat, beispielsweise ein Polyoxymethylen oder Polyacetal.Advantageously, the locking insert is integrally molded from a plastic injection molded part. The release lever is formed as well as the return spring. This production ensures economical production even with medium quantities. As the plastic is advantageously a thermoplastic resin of high strength, such as a thermoplastic polycondensate, for example a polyamide or polycarbonate, optionally with fiber reinforcement, or a plastic of high elasticity, such as a thermoplastic polymer, such as a polyoxymethylene or polyacetal.

Am Untergestell eines Stuhles (beides nicht näher dargestellt) sind beidseits Armstützen vorgesehen, die mit dem Untergestell verbunden sind, Dazu weist die Armstütze einen Armstützenhalter 15 auf, der mit einem Mittel zum Verbinden mit dem Untergestell des Stuhles - hier durch den Winkelansatz 15.1 dargestellt - versehen ist. Auf diesen so an den Stuhl gestellfest angesetzten Armstützenhalter 15 ist der Armstützenträger 10 mit seiner Hülse 11 so aufgesetzt, dass der Armstützenträgerkopf 10.1 freistehend die Armauflage 20 aufnehmen kann, die mittels der durch die Halteschraubenaufnahmen 14 geführten und in dieser verschraubten Halteschraube 21 angeschraubt wird. Diese an den Armstützenträgerkopf 10.1 angesetzte Führungshülse 11 nimmt den Armstützenhalter 15 so auf, dass die Führungshülse 11 zur Höhenverstellung in etwa vertikaler Richtung verschoben werden kann. Zum Ausgleich von Toleranzen und zum Hemmen der Bewegung sind Federeinlagen 15.2 zumindest einseitig an dem Armstützenhalter 15 angeordnet. Diese Federeinlagen 15.2 sind beispielsweise als Spange mit Schenkeln mit nach außen gerichteten Wellen ausgebildet, auf deren niedergedrückten Spitzen die Hülse 11 spielfrei mit leichtem Lauf gleitet und in Ruhe spielfrei ohne Klappern gelagert ist.On the underframe of a chair (both not shown in detail) armrests are provided on both sides, which are connected to the base, for this purpose, the armrest has an armrest holder 15 which is provided with a means for connecting to the base of the chair - here by the angle approach 15.1 - is provided. The armrest carrier 10 with its sleeve 11 is placed on this armrest holder 15, which is attached to the chair so as to be fixed to the chair. The armrest carrier head 10.1 can receive the armrest 20 in free-standing manner, which is screwed by means of the retaining screw 21 guided through the holding screw receptacles 14 and screwed therein. This attached to the Armstützenträgerkopf 10.1 guide sleeve 11 receives the armrest holder 15 so that the guide sleeve 11 can be moved for height adjustment in approximately vertical direction. In order to compensate for tolerances and to inhibit the movement, spring inserts 15. 2 are arranged at least on one side on the armrest holder 15. These spring inserts 15.2 are formed, for example, as a clasp with legs with outwardly directed waves on the depressed tips, the sleeve 11 slides smoothly with clearance and is stored in peace without play rattling.

Um die Höheneinstellung fixieren zu können, sind Rastmittel vorgesehen, die zum Bewegen ausgelöst werden können. Diese bestehen aus einem in einen korrespondierenden Schlitz in dem Armstützenhalter 15 eingesetzten Rasteinschub 17. Dieser ist etwa in Form eines rechtwinkligen Dreiecks ausgebildet, wobei an der dem rechten Winkel entsprechenden Ecke Achsstummel 17.2 vorgesehen sind Diese Achsstummel 17.2 werden in Achsstummelaufnahmen im Armstützenträgerkopf 10.1 eingesetzt, so dass der Rasteinschub 17 schwenkbar gehalten ist. Das Dreieck des Rasteinschubs 17 ist als spitzwinkliges Dreieck ausgebildet, an dessen Ecke mit dem stumpferen Winkel eine Auslösetaste 17.2 angesetzt ist. Diese Auslösetaste 17.2 ist aus dem Armstützenträgerkopf 10.1 so herausgeführt, dass der im Stuhl Sitzende diese Auslösetaste 17.2 ohne weiteres greifen und betätigen kann. Nahe der anderen, dem spitzen Winkel zugeordneten Ecke des dreieckigen Rasteinschubs 17 ist eine Rastnase 18 vorgesehen. Diese Rastnase greift in zwischen Stegen gebildeten Rastausnehmungen 16 ein und sperrt so eine Bewegbarkeit, auch wenn eine Kraft auf die Armauflage 20 ausgeübt wird. Schließlich ist an der diesem spitzen Winkel zugeordneten Ecke eine etwa U- oder v-förmige Rückstellfeder 19 angeformt, deren freies Ende gegen die geschlossene Rückseite der den Rasteinschub 17 aufnehmenden Schlitz des Armstützenhalters abgestützt ist.In order to fix the height adjustment, locking means are provided which can be triggered to move. These consist of one This is formed approximately in the form of a right triangle, which are provided at the right angle corresponding corner stub axle 17.2 These stub axles 17.2 are used in stub axle receptacles in the arm support carrier head 10.1, so that the locking insert 17th is held pivotally. The triangle of Rasteinschubs 17 is formed as an acute-angled triangle, at the corner with the obtuse angle, a release button 17.2 is attached. This release button 17.2 is led out of the armrest support head 10.1 so that the sitting in the chair this trigger button 17.2 can easily grab and operate. Near the other, the acute angle associated corner of the triangular Rasteinschubs 17 a latching nose 18 is provided. This locking lug engages in recesses 16 formed between webs and thus blocks a mobility, even if a force is exerted on the armrest 20. Finally, an approximately U- or V-shaped return spring 19 is formed at the angle associated with this acute angle, whose free end is supported against the closed rear side of the latch slot 17 receiving slot of the armrest holder.

Zum Bewegen wird die Auslösetaste 17.2 durchgedrückt. Dabei verlagert sich der Rasteinschub 17 in seine ausgelöste Position 17' - wie.in der Figur 1 durch die Überlagerung angedeutet. Bei dieser Bewegung wird die Rastnase 18 in die ausgelöste Position 18' bewegt, und sperrt dabei nicht mehr die Bewegbarkeit der Führungshülse 11 auf dem Armstützenhalter 15. Bei diesem Durchdrücken der Auslösetaste 17.2 wird mit der Bewegung des Rasteinschubs 17 die Rückstellfeder 19 in die ausgelöste Position 19' überführt und dabei gespannt. Diese so gespannte Rückstellfeder 19 sorgt dann beim Erreichen einer neuen Höhenposition, dass die Rastnase 18 wieder in eine der Rastausnehmungen 16 einfällt und so die gewünschte Höhen-Einstellung fixiert. Um eine Abziehen des Armstützenträgers 10 mit der Armauflage 20 zu verhindern, ist im Kopfbereich des Armstützenhalter 15 ein Sperrstift 13 angeordnet. Damit wird - wie in Figur 3 dargestellt - die Bewegbarkeit von Armstützenträgers 10 mit Armauflage 20 begrenzt.To move the shutter button 17.2 is pressed. In this case, the latching insert 17 shifts to its triggered position 17 '- wie.Im indicated in the figure 1 by the superposition. During this movement, the locking lug 18 is moved to the triggered position 18 ', and no longer locks the mobility of the guide sleeve 11 on the armrest holder 15. In this pressing the trigger button 17.2 is the return latch spring 19 in the triggered position with the movement of the latching insert 17 19 'convicted and curious. This tensioned return spring 19 then ensures when reaching a new height position that the locking lug 18 again falls into one of the recesses 16 and thus fixes the desired height setting. In order to prevent removal of the armrest support 10 with the armrest 20, a locking pin 13 is arranged in the head region of the armrest holder 15. Thus, as shown in FIG. 3, the mobility of the armrest support 10 with the armrest 20 is limited.
