Description

Die Erfindung betrifft ein Möbel mit einem Rahmen zum Sichern einer klappbaren Möbelsäule, sowie ein Verfahren zum Sichern einer klappbaren Möbelsäule.The invention relates to a piece of furniture with a frame for securing a folding furniture column, and a method for securing a folding furniture column.

Möbel mit klappbaren Säulen sind aus dem Stand der Technik bekannt, beispielsweise aus der Offenlegungsschrift DE 10 2011 076 409 A1 . Dort werden klappbare Möbelsäulen offenbart, die an einem Möbelrahmen mittels einem Befestigungsmittel 21 um eine Drehachse R drehbar angebracht sind. Zum Sichern der Möbelsäule in einer aufgerichteten Position weist die Säule eine Lasche mit einem Durchgangsloch 23 auf, welches mit einem am Rahmen des Möbels vorgesehenen Gewinde fluchtet, wenn sich die Möbelsäule in der aufgerichteten Position des Möbels befindet. An dieser Position kann daraufhin die Möbelsäule mittels einer Schraube (durch das Durchgangsloch 23 hindurch) am Rahmen (mittels dem Gewinde) gesichert werden, wodurch ein Zusammenklappen der Möbelsäule verhindert wird. Wenn ein solches Möbel beim Endkunden aufgebaut wird, muss der Monteur die Möbelsäule in die aufgerichtete Position klappen, und die Endlage der Säule mittels der erwähnten Schraube sichern. Dies geschieht dadurch, dass der Monteur die Schraube durch die Lasche der Säule hindurch mittels eines Schraubendrehers oder Akkuschraubers in das Gewinde des Rahmens hineindreht. Zum Aufstellen eines solchen Möbels wird demnach Werkzeug benötigt, wie beispielsweise der gerade erwähnte manuelle Schraubendreher oder ein Akkuschrauber.Furniture with folding columns are known from the prior art, for example from the published patent application DE 10 2011 076 409 A1 , There foldable furniture columns are disclosed which are rotatably mounted on a furniture frame by means of a fastening means 21 about a rotation axis R. To secure the furniture column in a raised position, the column has a tab with a through hole 23 which is aligned with a provided on the frame of the furniture thread when the furniture column is in the upright position of the furniture. At this position, the furniture column can then be secured by means of a screw (through the through hole 23) on the frame (by means of the thread), whereby a collapse of the furniture column is prevented. If such a piece of furniture is built up at the end customer, the installer must fold the furniture column in the erect position, and secure the end position of the column by means of the mentioned screw. This is done by the installer screwing the screw through the tab of the column by means of a screwdriver or a cordless screwdriver into the thread of the frame. To set up such a piece of furniture is therefore required tool, such as the just-mentioned manual screwdriver or a cordless screwdriver.

Zum Fixieren von Fahrradsätteln oder insbesondere Fahrradfelgen am Fahrradrahmen sind des Weiteren Schnellspanner oder Schnellspannvorrichtungen bekannt. Diese weisen einen Hebel, eine Verbindungsstange mit zwei Klemmstücken, sowie einen Exzenter auf. Durch Umlegen des Hebels werden die Spannstücke mittels einer Auslenkung des Exzenters aufeinander zubewegt, wodurch sich beispielsweise eine Fahrradfelge am Fahrradrahmen mittels Klemmung befestigen lässt. Die Stärke der Verspannung kann dabei dadurch eingestellt werden, dass wenigstens ein Klemmstück mit der Verbindungsstange durch ein Gewinde verbunden ist, sodass die relative Position des Klemmstücks an der Gewindestange durch Hinein- bzw. Herausdrehen (vordem Verspannen) eingestellt werden kann.For fixing bicycle saddles or especially bicycle rims on the bicycle frame are further quick release or Quick release devices known. These have a lever, a connecting rod with two clamping pieces, as well as an eccentric. By moving the lever, the clamping pieces are moved towards each other by means of a deflection of the eccentric, whereby, for example, a bicycle rim can be attached to the bicycle frame by means of clamping. The strength of the tension can be adjusted by at least one clamping piece being connected to the connecting rod by a thread, so that the relative position of the clamping piece on the threaded rod can be adjusted by screwing in or out (previously clamping).

Die Druckschrift DE 20 2006 011855 U1 offenbart einen Mechanismus zum Verstellen und Fixieren eines Tischbein mittels zweier Schnellspannerverschlüsse.The publication DE 20 2006 011855 U1 discloses a mechanism for adjusting and fixing a table leg by means of two quick release fasteners.

Die Druckschrift GB 489 991 A offenbart eine klappbare Verbindung zwischen einem Tischbein und einer Tischplatte mittels eines einschraubbaren Drehbolzens, wobei die Endposition des Tischbeins durch einen in eine U-förmige Kulisse einsetzbaren Sicherungsstift realisiert wird.The publication GB 489 991 A discloses a hinged connection between a table leg and a table top by means of a screw-in pivot pin, wherein the end position of the table leg is realized by an insertable into a U-shaped gate locking pin.

Es ist eine Aufgabe der vorliegenden Erfindung, einen Rahmen eines Möbels, ein Möbel mit einem Rahmen, sowie ein Verfahren zum Sichern (sowie zum Entsichern) einer klappbaren Säule an einem Möbel vorzusehen, wobei das Sichern der Möbelsäule am Möbel ohne Werkzeug ausführbar ist.It is an object of the present invention to provide a frame of a furniture, a furniture with a frame, and a method for securing (as well as for unlocking) a hinged column to a furniture, wherein the securing of the furniture column furniture without tools is executable.

Diese Aufgabe wird mittels eines Möbels, sowie mittels Verfahren gemäß der nebengeordneten Ansprüche gelöst.This object is achieved by means of a piece of furniture, as well as by means of methods according to the independent claims.

Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.Advantageous developments are the subject of the dependent claims.

Durch das vorzugsweise Konstruieren des Möbels auf solche Art und Weise, dass das Fixieren einer Säule mittels eines Verklemmens bzw. einer Verklemmung herbeiführbar ist, muss kein Werkzeug zum Anbringen von beispielsweise einer Schraube verwendet werden. Erfindungsgemäß weist der Rahmen eine Lagerung auf, mittels welcher die Möbelsäule drehbar am Rahmen befestigt ist. Diese Lagerung ist vorzugsweise so ausgeführt, dass im Rahmen ein Bolzen oder eine Schraube fixiert ist, welche die Säule am Rahmen fixiert, aber eine drehende Bewegung der Säule bezüglich des Rahmens um eine Achse ermöglicht. Wenn ein erfindungsgemäßes Möbel mit dem Rahmen und den klappbaren Säulen aufgestellt werden soll, werden die Säulen in eine aufrechte, also eine senkrechte Position (in eine Standposition) bewegt. In dieser Position müssen die Säulen zum Gewährleisten eines sicheren Stands am Rahmen fixiert werden. Vorzugsweise ist der Rahmen so konstruiert, dass diese Fixierung nicht mittels einer Schraube oder eines Bolzens vorgenommen wird, sondern durch Verklemmen der Säule im oder am Rahmen. Vorzugsweise wird die Säule dazu zwischen zwei Teilstücken des Rahmens eingeklemmt. Die Erfindungsidee bezieht sich im Allgemeinen darauf, dass das Fixieren einer Drehmöglichkeit zwischen eines Möbels und einer daran angebrachten drehbaren Säule durch das Prinzip des Einklemmens bzw. Verklemmens von wenigstens zwei Teilen miteinander ausgeführt wird. Mittels des Verklemmens wird zwischen Rahmen und klapp- bzw. drehbarer Säule eine Anpresskraft ausgeübt. Durch diese Anpresskraft wird eine Reibkraft verursacht, welche Rahmen und Säule bezüglich einander festhält bzw. fixiert. Vorzugsweise weisen die zum Verklemmen vorgesehenen Kontaktflächen von Säule und Rahmen einen hohen Reibungskoeffizienten auf. Vorzugsweise ist insbesondere der Haftreibungskoeffizient dieser Flächen hoch.By preferably constructing the furniture in such a way that the fixing of a column by means of jamming or jamming can be brought about, no tool for attaching, for example, a screw must be used. According to the invention, the frame has a bearing, by means of which the furniture column is rotatably mounted on the frame. This storage is preferably designed so that in the frame a bolt or a screw is fixed, which supports the column on Fixed frame, but allows a rotating movement of the column with respect to the frame about an axis. When a furniture according to the invention is to be set up with the frame and the folding columns, the columns are moved into an upright, ie a vertical position (in a standing position). In this position, the columns must be fixed to the frame to ensure a secure footing. Preferably, the frame is constructed so that this fixation is not made by means of a screw or a bolt, but by jamming the column in or on the frame. Preferably, the column is clamped between two sections of the frame. The inventive idea generally refers to the fact that the fixing of a rotation possibility between a piece of furniture and a rotatable column attached thereto is carried out by the principle of clamping or clamping at least two parts together. By means of jamming a contact force is exerted between the frame and hinged or rotatable column. By this contact force, a frictional force is caused, which holds frame and column with respect to each other or fixed. Preferably, the clamping surfaces of the pillar and the frame provided for clamping have a high coefficient of friction. In particular, the static friction coefficient of these surfaces is preferably high.

Vorzugsweise weist der Rahmen eine Fixierung auf, welche durch einen Monteur bedienbar ist. Durch ein entsprechendes Bedienen der Fixierung kann eine einklemmende Wirkung herbeigeführt und aufrechterhalten werden. Säule und Rahmen sind in eine aufgerichtete Position bringbar und daraufhin bezüglich einander fixierbar, aufgrund der Bedienung der Fixierung. Durch das vorzugsweise Vorsehen der Fixierung kann die fixierende Wirkung durch einen Monteur ohne die Zuhilfenahme von Werkzeug herbeigeführt werden.Preferably, the frame has a fixation, which can be operated by a fitter. By a corresponding operation of the fixation, an entrapment effect can be brought about and maintained. Column and frame can be brought into an upright position and then fixed with respect to each other, due to the operation of the fixation. By preferably providing the fixation, the fixing effect can be brought about by a fitter without the aid of tools.

Durch das Vorsehen der Fixierung am Rahmen, und nicht an der klappbaren Säule, wird der Aufstellvorgang eines klappbaren Möbels dahingehend vereinfacht, dass die Säule aufgrund eines geringeren Gewichts einfacher und sicherer in die gewünschte (aufgerichtete) Lage bringbar ist, was das Handling des Aufstellvorgangs verbessert. Falls die Fixierung an der klappbaren Säule angebracht wäre, würde eine solche Konstruktion das Gewicht der Säule erhöhen, wodurch das Aufrichten und Halten der Säule durch einen Monteur erschwert werden würde. Durch das vorzugsweise Vorsehen eines Exzenters, der mittels eines Verbindungsstücks ein erstes und ein zweites Klemmelement aufeinander zubewegen und dadurch einen dazwischen angeordneten Teil einer Säule einklemmen kann, ist eine Konstruktion zum Einklemmen eines Bauteils besonders kostengünstig ausführbar. Eine solche Konstruktion ist des Weiteren besonders einfach bedienbar, ohne Zuhilfenahme von Werkzeug.By providing the fixation on the frame, and not on the hinged column, the Aufstellvorgang a folding furniture is simplified in that the column is easier and safer in the desired (upright) position can be brought due to a lower weight, which improves the handling of the deployment , If the fixation were attached to the foldable column, such a construction would increase the weight of the column, which would make it difficult for a fitter to erect and hold the column. By preferably providing an eccentric, which by means of a connecting piece a first and a second clamping element move towards each other and thereby clamp a part of a column arranged therebetween, a construction for clamping a component is particularly cost executable. Such a construction is furthermore particularly easy to operate, without the aid of tools.

Durch das vorzugsweise Vorsehen eines klappbaren Hebels an dem Exzenter kann eine einklemmende Wirkung durch ein Bedienen des Hebels durch einen Monteur herbeigeführt werden. Vorzugsweise ist der Rahmen so konstruiert, dass der Hebel die klappbare Säule in einem angeklappten Zustand fixiert, d.h. in einem an den Rahmen angeklappten Zustand. Des Weiteren ist der Rahmen vorzugsweise so konstruiert, dass die klappbare Säule am Rahmen nicht fixiert wird, wenn der Hebel vom Rahmen weggeklappt ist. Dadurch ist leicht erkennbar, ob der fixierende Zustand bzw. die fixierende Wirkung der Fixierung zu einem aktuellen Zeitpunkt hergestellt ist, oder nicht.By preferably providing a hinged lever on the eccentric a clamping effect can be brought about by operating the lever by a fitter. Preferably, the frame is constructed so that the lever fixes the folding column in a folded state, i. in a folded state on the frame. Furthermore, the frame is preferably constructed so that the hinged pillar is not fixed to the frame when the lever is folded away from the frame. As a result, it can be easily recognized whether or not the fixing state or the fixing effect of fixation is established at a current time.

Vorzugsweise weist die Fixierung wenigstens eine Einstellmöglichkeit auf, um die gewünschte Verspannung der Verklemmung einzustellen. Denn nur wenn die Verspannung des Fixierungselements in der fixierten Lage richtig und korrekt eingestellt ist, kann ein funktionierender Montagevorgang sowie ein dauerhaftes Sichern bzw. Fixieren der klappbaren Säule am Rahmen eines Möbels in der vorgesehenen Position gewährleistet werden.Preferably, the fixation has at least one adjustment to the desired tension of the deadlock adjust. For only if the tension of the fixing element is set correctly and correctly in the fixed position, a functioning assembly process and a permanent securing or fixing the hinged column on the frame of a piece of furniture in the intended position can be ensured.

Um zu verhindern, dass sich die klappbare Säule trotz des fixierten Zustandes (durch Klemmung) aus der aufgerichteten Lage herausbewegt, und damit ein Zusammenklappen eines Möbels verursachen würde, ist erfindungsgemäß ein Sicherungselement am Rahmen vorgesehen. Dieses Sicherungselement ist vorzugsweise im oder am Rahmen gelagert und greift vorzugsweise (in einer sichernden Position) senkrecht zur Bewegungsrichtung der klappbaren Säule in die klappbare Säule ein, und verhindert ein Bewegen der klappbaren Säule bezüglich des Rahmens. Falls durch eine äußere Krafteinwirkung eine Relativbewegung zwischen Rahmen und Säule ausgelöst werden würde, sichert das Sicherungselement Rahmen und klappbare Säule mittels Formschluss bezüglich einander, wodurch ein Bewegen von klappbarer Säule und Rahmen bezüglich einander verhindert wird. Beim Verhindern einer solchen Bewegung wird das Sicherungselement auf Scherung beansprucht.In order to prevent the folding column from moving out of the erected position (due to clamping) despite the fixed state, and thus causing the furniture to collapse, a securing element is provided on the frame according to the invention. This securing element is preferably mounted in or on the frame and preferably engages (in a locking position) perpendicular to the direction of movement of the folding column in the hinged column, and prevents movement of the folding column with respect to the frame. If a relative movement between the frame and column would be triggered by an external force, secures the fuse element frame and folding column by means of positive locking with respect to each other, whereby a movement of hinged column and frame is prevented relative to each other. In preventing such movement, the fuse element is subjected to shear.

Erfindungsgemäß ist das Sicherungselement so angeordnet, dass dieses durch den Hebel, der zum Bedienen des optionalen Exzenters bzw. der Fixierung vorgesehen ist, in eine sichernde Position bringbar ist. Erfindungsgemäß ist das Sicherungselement so angeordnet, dass dieses durch den Hebel der Fixierung in der sichernden Lage gehalten wird, wenn sich der Hebel in dem an den Rahmen angeklappten Zustand befindet, in welchem die Fixierung die klappbare Säule im Rahmen einklemmt. Durch eine solche Konstruktion wird das Sicherungselement automatisch aktiviert, sobald die Fixierung durch Bedienen des Hebels aktiviert wird. Dadurch kann ein Aktivieren des Sicherungselements durch einen Monteur nicht vergessen werden. Das Sicherungselement wird vorzugsweise durch den Hebel in eine sichernde Position gebracht, wenn dieser ein Verspannen der Fixierung auslöst.According to the invention, the securing element is arranged such that it can be brought into a locking position by the lever which is provided for operating the optional eccentric or the fixing. According to the invention, the securing element is arranged so that it is held by the lever of the fixing in the locking position when the lever is in the folded state to the frame, in which the fixation clamps the folding column in the frame. By such a construction, the securing element is automatically activated as soon as the fixation is activated by operating the lever. This allows activation of the fuse element by a fitter not to be forgotten. The securing element is preferably brought by the lever in a locking position, if this triggers a distortion of the fixation.

Vorzugsweise weist der Rahmen eine Feder auf, die so angeordnet ist, dass das Sicherungselement mittels der Federkraft der Feder in eine Position gedrückt wird, in welcher sie die klappbare Säule nicht am Rahmen sichert. Dadurch wird das Sicherungselement automatisch deaktiviert, sobald der Hebel der Fixierung vom Monteur in eine Lage bewegt wird, in welcher die klemmende Wirkung der Fixierung aufgelöst ist.

Figur 1 zeigt eine Draufsicht auf einen Rahmen 1. Dabei ist eine auf dem Rahmen 1 gelagerte Tischplatte 3 nicht dargestellt. Im linken Bereich der Darstellung ist ein von oben nach unten verlaufender Querträger des Rahmens 1 dargestellt, wobei im mittleren und rechten Bereich der Darstellung ein von rechts nach links verlaufender Längsträger des Rahmens 1 dargestellt ist. Eine Lagerung 11 lagert eine klappbare Säule 2 drehbar in dem Rahmen 1. Mittels der Lagerung 11 ist die Säule 2 drehbar um die Achse A innerhalb des Rahmens 1 festgelegt. Im dargestellten nicht erfindungsgemäßen Ausführungsbeispiel ist die Lagerung 11 dadurch ausgeführt, dass eine Schraube in ein in der Säule 2 vorgesehenes Gewinde eingeschraubt wird, wobei der Rahmen 1 Durchgangslöcher zum Durchführen des Schraubenschafts aufweist. Eine Fixierung 12 wird im gezeigten nicht erfindungsgemäßen Ausführungsbeispiel durch ein erstes Klemmelement 121, ein Verbindungsstück 123, ein zweites Klemmelement 122, einen Exzenter 124, sowie einen Hebel 125 gebildet. Das Verbindungsstück 123 weist an ihrem dem Exzenter 124 abgewandten Ende ein Außengewinde auf, auf welches das erste Klemmelement 121 aufgeschraubt ist. Am anderen Ende des Verbindungsstücks 123 ist der Exzenter 124 angeordnet, wobei zwischen Exzenter 124 und Rahmen 1 ein zweites Klemmelement 122 eingefügt ist. Dieses zweite Klemmelement 122 ist nicht mit dem Verbindungsstück 123 verbunden, sondern wird lediglich auf diesem axial gelagert. Das zweite Klemmelement 122 weist ein rundes Durchgangsloch auf, zum Aufnehmen des Verbindungsstücks 123. Der Exzenter 124 ist einstückig mit einem Hebel 125 ausgebildet. In der gezeigten Darstellung befindet sich der Hebel 125 in einer von dem Rahmen 1 weggeklappten Position. In dieser Position des Hebels 125 ist der Exzenter 124 so ausgerichtet, dass keine klemmende Wirkung zwischen dem ersten Klemmelement 121 und dem zweiten Klemmelement 122 ausgeübt wird. Zum Ausüben einer klemmenden Wirkung ist der Exzenter 124 mit dem Verbindungsstück 123 so verbunden, dass der Exzenter 124 auf der Achse des Verbindungsstücks 123 nicht bewegbar ist, wobei der Exzenter 124 aber mittels einer Drehung um eine aus der Blattebene herausragenden Achse den Abstand zwischen der aus der Blattebene herausragenden Achse und dem zweiten Klemmelement 122 vergrößert, wodurch der Abstand zwischen dem zweiten Klemmelement 122, das auf dem Verbindungsstück 123 axial verschiebbar gelagert ist, und dem ersten Klemmelement 121 verringert. Dadurch tritt eine einklemmende Wirkung zwischen dem ersten Klemmelement 121 und dem zweiten Klemmelement 122 auf, wodurch der Rahmen 1 im Bereich der ersten und zweiten Klemmelemente 121, 122 in geringem Maße elastisch nach innen verformt, und dadurch eine anpressende Kraft auf die klappbare Säule 2 ausübt. Somit ist die klappbare Säule 2 innerhalb des Rahmens 1 einklemmbar. FIG. 1 shows a plan view of a frame 1. In this case, a mounted on the frame 1 table top 3 is not shown. In the left area of the illustration, a cross member running from top to bottom of the frame 1 is shown, wherein in the middle and right area of the illustration, a right-to-left side member of the frame 1 is shown. A bearing 11 supports a hinged column 2 rotatably in the frame 1. By means of the bearing 11, the column 2 is rotatably fixed about the axis A within the frame 1. In the non-inventive embodiment shown, the bearing 11 is designed by screwing a screw into a thread provided in the column 2, wherein the frame 1 has through-holes for passing through the screw shaft. A fixing 12 is formed in the non-inventive embodiment shown by a first clamping element 121, a connecting piece 123, a second clamping element 122, an eccentric 124, and a lever 125. The connecting piece 123 has at its end remote from the eccentric 124 an external thread onto which the first clamping element 121 is screwed. At the other end of the connecting piece 123 of the eccentric 124 is arranged, wherein between the eccentric 124 and frame 1, a second clamping element 122 is inserted. This second clamping element 122 is not connected to the connecting piece 123, but is merely axially mounted thereon. The second clamping element 122 has a round through hole for receiving the connecting piece 123. The eccentric 124 is formed integrally with a lever 125. In the illustration shown, the lever 125 is in a folded away from the frame 1 position. In this position of the lever 125, the eccentric 124 is aligned so that no clamping effect between the first clamping member 121 and the second clamping member 122 is applied. To exert a clamping effect of the eccentric 124 is connected to the connecting piece 123 so that the eccentric 124 on the Axis of the connecting piece 123 is not movable, wherein the eccentric 124 but by means of a rotation about an axis protruding from the plane of the sheet increases the distance between the plane protruding from the plane and the second clamping element 122, whereby the distance between the second clamping element 122, the on the connection piece 123 is mounted axially displaceable, and the first clamping element 121 is reduced. As a result, a clamping effect occurs between the first clamping element 121 and the second clamping element 122, as a result of which the frame 1 elastically deforms to a slight extent in the region of the first and second clamping elements 121, 122 and thereby exerts a pressing force on the foldable column 2 , Thus, the hinged column 2 can be clamped within the frame 1.

Figur 2 zeigt das nicht erfindungsgemäße Ausführungsbeispiel aus Figur 1, wobei sich der Hebel 125 in einem an den Rahmen 1 angeklappten Zustand befindet, in welchem der Exzenter 124 (wie oben beschrieben) so ausgerichtet ist, dass zwischen dem ersten Klemmelement 121 und dem zweiten Klemmelement 122 eine einklemmende Kraft ausgeübt wird, wodurch die klappbare Säule 2 innerhalb des von links nach rechts verlaufenden Teils des Rahmens 1 eingeklemmt wird, wodurch die klappbare Säule 2 innerhalb des Rahmens 1 fixiert wird. FIG. 2 shows the embodiment not according to the invention FIG. 1 , wherein the lever 125 is in a folded state to the frame 1, in which the eccentric 124 (as described above) is aligned so that between the first clamping member 121 and the second clamping member 122 a clamping force is applied, whereby the hinged Pillar 2 is clamped within the left-to-right portion of the frame 1, whereby the hinged column 2 is fixed within the frame 1.

Mittels des ersten Klemmelements 121 ist die Fixierung 12 aus den in Figur 1 und Figur 2 gezeigten nicht erfindungsgemäßen Ausführungsbeispielen durch Ein- bzw. Ausschrauben des Gewindes axial auf dem Verbindungsstück 123 verschiebbar. Das dazu vorgesehene Gewinde weist eine selbstsichernde Wirkung auf. Durch Ein- bzw. Ausschrauben des Gewindes im ersten Klemmelement 121 ist die Klemmwirkung bzw. die Stärke der Klemmwirkung einstellbar. Denn durch Ein- bzw. Ausschrauben des ersten Klemmelements 121 ist der Abstand des ersten Klemmelements 121 und des zweiten Klemmelements 122 variierbar, wodurch die Stärke der Klemmwirkung einstellbar ist. Während die Fixierung 12 mittels des Hebels 125 gelöst ist, kann durch Ein- bzw. Ausschrauben des ersten Klemmelements 121 die Klemmstärke justiert werden. Wenn ein Monteur während dem Umlegen des Hebels 125 zum Fixieren der Säule spürt, dass der Hebel zu leichtgängig oder zu schwergängig ist, wodurch der Monteur auf die Stärke der Fixierung schließen kann, ist es somit möglich, die Klemmstärke durch Ein- bzw. Ausschrauben des ersten Klemmelements 121 anzupassen.By means of the first clamping element 121 is the fixation 12 of the in FIG. 1 and FIG. 2 shown non-inventive embodiments by screwing or unscrewing the thread axially on the connecting piece 123 slidably. The thread provided for this purpose has a self-locking effect. By screwing or unscrewing the thread in the first clamping element 121, the clamping action or the strength of the clamping action is adjustable. Because by screwing in or unscrewing the first clamping member 121 is the distance the first clamping member 121 and the second clamping member 122 variable, whereby the strength of the clamping action is adjustable. While the fixing 12 is released by means of the lever 125, the clamping strength can be adjusted by screwing in or unscrewing the first clamping element 121. Thus, when a fitter senses that the lever is too slippery or too tight during the folding of the column fixing lever 125, which allows the installer to judge the strength of the fixture, it is possible to increase the clamping strength by screwing in or unscrewing the column first clamping element 121 adapt.

Im in Figur 3 gezeigten erfindungsgemäßen Ausführungsbeispiel sind die von links nach rechts verlaufenden Teilstücke des Rahmens 1 doppelwandig ausgeführt. Die Ausgestaltung der Lagerung 11 ist zu den vorhergehenden nicht erfindungsgemäßen Ausführungsbeispielen identisch. Allerdings ist der Exzenter 124 auf dem Verbindungsstück 123 nicht axial festgelegt, sondern zwischen einem Einstellelement 126 und dem zweiten Klemmelement 122 auf der Achse des Verbindungsstücks 123 verschiebbar. Das erste Klemmelement 121 ist wie in den vorherigen nicht erfindungsgemäßen Ausführungsbeispielen mittels einem Gewinde auf das Verbindungsstück 123 aufgeschraubt. In einem nicht dargestellten Ausführungsbeispiel ist das erste Klemmelement 121 mit dem Verbindungsstück 123 einstückig ausgebildet oder auf dieses aufgepresst. Des Weiteren ist das Einstellelement 126 auf der anderen Seite des Verbindungstücks 123 auf dieses mittels einem selbstsichernden Gewinde aufgeschraubt. Durch Ein- bzw. Ausschrauben des Einstellelements 126 ist der Abstand zwischen Einstellelement 126 und erstem Klemmstück 121 variierbar, wodurch die Stärke der einklemmenden Wirkung des Exzenters 124 einstellbar ist. Im in Figur 3 gezeigten Ausführungsbeispiel befindet sich der Hebel 125 in einem von dem Rahmen 1 weggeklappten Zustand, in welchem der Exzenter 124 keine einklemmende Wirkung auf die klappbare Säule 2 ausübt. In dem in Figur 3 gezeigten Ausführungsbeispiel ist im Gegensatz zu den vorherigen nicht erfindungsgemäßen Ausführungsbeispielen ein Einstellen der einklemmenden Wirkung mittels des Gewindes in dem Einstellelement 126 möglich, im Gegensatz zu den vorherigen gezeigten nicht erfindungsgemäßen Ausführungsbeispielen, in welchen das Einstellen durch das Gewinde des ersten Klemmelements 121 ausführbar ist. Im in Figur 3 gezeigten Ausführungsbeispiel ist das erste Klemmelement 121 im Rahmen 1 fest montiert.Im in FIG. 3 shown embodiment of the invention, the running from left to right portions of the frame 1 are double-walled. The design of the bearing 11 is identical to the preceding embodiments not according to the invention. However, the eccentric 124 is not axially fixed on the connecting piece 123, but displaceable between an adjusting element 126 and the second clamping element 122 on the axis of the connecting piece 123.

In one embodiment, not shown, the first clamping element 121 is formed integrally with the connector 123 or pressed onto this. Furthermore, the adjusting member 126 is screwed on the other side of the connecting piece 123 on this by means of a self-locking thread. By screwing in or unscrewing the adjusting member 126, the distance between the adjusting member 126 and the first clamping piece 121 is variable, whereby the strength of the clamping effect of the eccentric 124 is adjustable. Im in FIG. 3 In the embodiment shown, the lever 125 is in a state folded away from the frame 1, in which the eccentric 124 exerts no clamping effect on the foldable column 2. In the in figure 3 shown embodiment, in contrast to the previous non-inventive embodiments, a setting of the clamping effect by means of the thread in the adjusting member 126 is possible, in contrast to the previous non-inventive embodiments shown in which the setting by the thread of the first clamping member 121 is executable. Im in FIG. 3 In the embodiment shown, the first clamping element 121 is fixedly mounted in the frame 1.

Des Weiteren weist das in Figur 3 gezeigte Ausführungsbeispiel ein Sicherungselement 13 auf, welches axial durch eine Öffnung im Rahmen 1 geführt ist, und mittels einer Feder 15 bezüglich der Darstellung in Figur 3 nach unten gedrückt wird. Durch das Ausüben einer Kraft auf das Sicherungselement 13 von unten nach oben, entgegen der Federkraft, ist dieses nach oben bewegbar, wobei es in eine Durchgangsbohrung, die innerhalb der klappbaren Säule 2 vorgesehen ist, in die klappbare Säule 2 einschiebbar ist.Furthermore, the in FIG. 3 shown embodiment, a securing element 13 which is guided axially through an opening in the frame 1, and by means of a spring 15 with respect to the representation in FIG. 3 is pressed down. By exerting a force on the securing element 13 from bottom to top, against the spring force, this is upwardly movable, being in a through hole, which is provided within the folding column 2, in the folding column 2 can be inserted.

Figur 4 zeigt das in Figur 3 dargestellte Ausführungsbeispiel, wobei sich der Hebel 125 in einer an den Rahmen 1 angeklappten Position befindet, wodurch der Exzenter 124 (durch Wegdrücken von dem Einstellelement 126) mittels dem ersten Klemmelement 121 und dem zweite Klemmelement 122 eine einklemmende Kraft auf die Säule 2 ausübt, wodurch die klappbare Säule 2 innerhalb des Rahmens 1 eingeklemmt wird. Durch die Position des Hebels 125 wird des Weiteren das Sicherungselement 13 entgegen der Federkraft der Feder 15 in die klappbare Säule 2 hineingedrückt, wodurch die klappbare Säule 2 zusätzlich zu der einklemmenden Wirkung der Fixierung 12 bezüglich des Rahmens 1 in ihrer Position gesichert wird. FIG. 4 shows that in FIG. 3 illustrated embodiment, wherein the lever 125 is in a folded position on the frame 1, whereby the eccentric 124 (by pushing away of the adjusting member 126) by means of the first clamping member 121 and the second clamping member 122 exerts a clamping force on the column 2, whereby the folding column 2 is clamped within the frame 1. By the position of the lever 125, the securing element 13 is further pressed against the spring force of the spring 15 in the hinged column 2, whereby the hinged column 2 is secured in addition to the clamping effect of the fixation 12 with respect to the frame 1 in position.

Falls der Hebel 125 von der in Figur 4 gezeigten Position (Verklemmung aktiviert) in die in Figur 3 gezeigte Position (Verklemmung nicht aktiviert) umgelegt wird, drückt die Feder 15 das Sicherungselement 13 von der in Figur 4 gezeigten Position (Sicherung aktiviert) in die in Figur 3 gezeigte Position (Sicherung nicht aktiviert).If the lever 125 from the in FIG. 4 shown position (Deadlock activated) in the in FIG. 3 shown position (deadlock not activated) is folded, the spring 15 presses the securing element 13 of the in FIG. 4 shown position (fuse activated) in the in FIG. 3 shown position (fuse not activated).
