Die Klemmflanke kann dem zweiten Tragelement zugeordnet sein. Das Klemmelement kann von einem schwenkbaren Klemmhebel ausgebildet sein. Das Klemmelement kann beweglich in einer Höhlung des Tragelementes angeordnet sein. Bei dem Tragelement kann es sich um ein Rohr, insbesondere um ein Vierkantrohr handeln. In der Höhlung des Rohres kann sich das Klemmelement befinden. Es kann um eine Schwenkachse schwenkbar im Rohr angeordnet sein. Die Rohrwandung kann ein Fenster besitzen, welches eine Schlitzform aufweisen kann. Durch dieses Fenster ragt ein Kopf des Klemmelementes nach außen. Dort befindet sich die Klemmflanke, die insbesondere von einer Randkante einer Flanschplatte ausgebildet ist, die fest mit dem zweiten Tragelement verbunden ist. Diese Klemmflanke verläuft im spitzen Winkel zur Schwenkebene des Klemmelementes, wobei der Winkel geringer ist als der maximale Selbsthemmungswinkel, so dass das Klemmelement in der Klemmstellung unter Ausübung eines Drehmomentes um die Schwenkachse der beiden Tragelemente an der Klemmflanke anliegt. Dabei stützt sich ein Abschnitt des Kopfes des Klemmelementes an der Klemmflanke und ein diesem Abschnitt gegenüberliegender Abschnitt des Kopfes des Klemmelementes an einer Randkante des Schlitzes ab, durch den das Klemmelement von der Höhlung des Tragelementes nach außen hindurchragt. In einer Weiterbildung der Erfindung ist vorgesehen, dass das Klemmelement durch eine Verlagerung eines Betätigungsgliedes von der Verriegelungsstellung, die der Klemmstellung entspricht, in die Freigabestellung verlagerbar ist. Das Betätigungsglied kann ein Fenster aufweisen und innerhalb der Rohrhöhlung des Tragelementes verlagerbar sein. Der Hebelarm des Klemmelementes durchgreift das Fenster des Betätigungsgliedes. Letzteres besitzt eine Druckflanke und eine Hubflanke. Das Betätigungsglied kann von einer Feder, insbesondere einer Zugfeder in Richtung der Klemmstellung belastet sein. Die Druckflanke des Fensters beaufschlagt das Klemmelement in Richtung seiner Klemmstellung. Wird das Betätigungsglied gegen die Rückstellkraft der Feder verlagert, so greift nach Durchlaufen eines Bewegungsspiels die Hubflanke, die der Druckflanke gegenüberliegt, am Hebelarm des Klemmelementes an, um das Klemmelement in die Freigabestellung zu bringen. In dieser Freigabestellung liegt der Kopf des Klemmelementes, der insbesondere eine schräge Stirnfläche aufweist, in der Öffnungsebene des Fensters des Tragelementes, vor welchem sich beim Verschwenken der beiden Tragelemente eine Breitseitenfläche der Flanschplatte verlagert, an der sich die Stirnfläche des Klemmelementes abstützen kann, wenn sich das Betätigungsglied aufgrund der Kraft der an ihm angreifenden Feder wieder zurückverlagert, so dass die Druckflanke das Klemmelement beaufschlagt.First and foremost, it is provided that the holding means have a clamping element. The clamping element can be brought from a locking position into a release position. The clamping element is in the position of use of the support frame to a clamping edge by clamping. The clamping element may be associated with the first support element. The clamping flank can be assigned to the second support element. The clamping element may be formed by a pivotable clamping lever. The clamping element can be movably arranged in a cavity of the support element. The support element may be a pipe, in particular a square pipe. In the cavity of the tube, the clamping element may be located. It can be arranged pivotably about a pivot axis in the pipe. The pipe wall may have a window, which may have a slot shape. Through this window, a head of the clamping element protrudes to the outside. There is the clamping edge, which is formed in particular by a peripheral edge of a flange plate which is fixedly connected to the second support member. This clamping edge extends at an acute angle to the pivot plane of the clamping element, wherein the angle is less than the maximum self-locking angle, so that the clamping element rests in the clamping position while exerting a torque about the pivot axis of the two support elements on the clamping edge. In this case, a portion of the head of the clamping element is supported on the clamping edge and a portion of the head of the clamping element opposite this section at an edge of the Slit through which the clamping element protrudes from the cavity of the support element to the outside. In a further development of the invention it is provided that the clamping element is displaceable by a displacement of an actuating member of the locking position corresponding to the clamping position in the release position. The actuator may have a window and be displaceable within the tube cavity of the support element. The lever arm of the clamping element passes through the window of the actuator. The latter has a pressure flank and a lifting flank. The actuator may be loaded by a spring, in particular a tension spring in the direction of the clamping position. The pressure edge of the window acts on the clamping element in the direction of its clamping position. If the actuating member is displaced against the restoring force of the spring, the lifting flank lying opposite the pressure flank, after passing through a movement play, engages on the lever arm of the clamping element in order to bring the clamping element into the release position. In this release position, the head of the clamping element, which in particular has an oblique face, in the opening plane of the window of the support element, in front of which displaces a broad side surface of the flange during pivoting of the two support elements, on which the end face of the clamping element can be supported, if the actuator due to the force of the spring acting on it shifted back again, so that the pressure edge acts on the clamping element.
In einer bevorzugten Weiterbildung weisen die Halteelemente Festanschläge auf. Die Festanschläge können einen Anschlag, insbesondere einen stiftförmigen Anschlag aufweisen, der dem ersten Tragelement zugeordnet ist. In der Gebrauchsstellung kann an diesem Anschlag ein Gegenanschlag des anderen Tragelementes anliegen. Insbesondere wird der Gegenanschlag von einer Anschlagnische der Flanschplatte ausgebildet. Die Festanschläge können in der Klemmstellung die Klemmkraft aufnehmen, die das Klemmelement auf die Klemmflanke überträgt. In einer Weiterbildung der Erfindung ist ein Rastzapfen vorgesehen, der in der Verriegelungsstellung in einer Rastnische einliegt. Der Rastzapfen kann dem ersten Tragelement und die Rastnische dem zweiten Tragelement, insbesondere der Flanschplatte zugeordnet sein. Der Rastzapfen kann fest am Betätigungsglied sitzen, so dass er zusammen mit dem Klemmelement bei einer Verlagerung des Betätigungsgliedes von der Verriegelungsstellung in eine Freigabestellung gebracht werden kann. In der Freigabestellung kann der Rastzapfen beim Verschwenken der beiden Tragelemente an einer Führungsflanke eines Führungsschlitzes entlang gleiten. Die Führungsflanke erstreckt sich auf einer Kreisbogenlinie um die Schwenkachse, um die die beiden Tragelemente schwenkbar sind. Die Achse, um die die beiden Tragelemente verschwenkbar sind, verläuft quer zur Erstreckungsebene der Flanschplatte. Sie erstreckt sich quer zur Flächenerstreckung zweier parallel zueinander verlaufender Wände des rohrförmigen Tragelementes. Die Schwenkachse, um die das Klemmelement schwenkbar ist, verläuft hingegen parallel zur Flächenerstreckungsebene dieser beiden Rohrwände. Die Schwenkebene des Klemmelementes verläuft insbesondere quer zur Flächenerstreckung zweier quer zu den ersten Rohrwänden verlaufenden zweiten Rohrwänden des einen rechteckigen Querschnitt aufweisenden Rohres, welches das erste Tragelement ausbildet. In einer bevorzugten Ausgestaltung der Erfindung erstreckt sich das zweite Tragelement in der Gebrauchsstellung in etwa in einer Horizontalebene. Das erste Tragelement besitzt an seinem unteren Ende einen ersten Fuß. Benachbart zum unteren Ende ist das zweite Tragelement am ersten Tragelement angelenkt. Das freie Ende des zweiten Tragelementes bildet einen zweiten Fuß aus. Es sind zwei Beinpaare vorgesehen, die jeweils ein erstes Tragelement und ein zweites Tragelement aufweisen, so dass das Tragegestell insgesamt vier Füße besitzt. Die beiden Tragelementpaare sind über Verbindungselemente miteinander verbunden. Bei den Verbindungselementen kann es sich um starre Traversen handeln, die jeweils zwei erste Tragelemente und jeweils zwei zweite Tragelemente starr miteinander verbinden. In dem sich in der Gebrauchsstellung nach oben erstreckenden ersten Tragelement kann sich ein Stützelement befinden. Das weitere Stützelement kann teleskopierbar dem ersten Tragelement zugeordnet sein. Ein am Ende des weiteren Stützelementes befestigter Träger kann somit auf verschiedene Arbeitshöhen gebracht werden. Der Träger trägt insbesondere in einer Horizontalebene aufeinander zu verlagerbare Spannbacken, die eine Werktischoberfläche ausbilden. Ein Zugelement, bei dem es sich um eine Zugstange handeln kann, greift am Betätigungsglied an. Ein Zugende des Zugelementes befindet sich innerhalb des weiteren Tragelementes, welches einen Längsschlitz besitzt, durch welchen ein Endabschnitt des Zuggliedes aus dem rohrförmigen weiteren Tragelement hinausragt. Dort ist das Zugelement mit einer Handhabe verbunden. Bei der Handhabe kann es sich um einen Querriegel handeln, der sich parallel zu den Verbindungselementen erstreckt, und an dem die Hand eines Benutzers angreifen kann, um einen Zug auf das Zugelement auszuüben, mit dem das Betätigungsglied gegen die Rückstellkraft der Feder verlagert werden kann, um das Klemmelement in die Freigabestellung zur bringen. Einhergehend damit wird auch der Rastzapfen aus der Rastnische ausgehoben, so dass das zweite Tragelement, bei welchem es sich um ein Fußelement handelt, von der Gebrauchsstellung in eine Nicht-Gebrauchsstellung verschwenkt werden kann. Die Erfindung betrifft darüber hinaus auch eine Weiterbildung der Verrastung des Stützelementes im schräg nach oben ragenden Tragelement. In einer Weiterbildung der Erfindung ist ein Tragegestell mit einem auf einem Untergrund aufstellbaren Untergestell, welches zumindest ein schräg in einer Vertikalebene nach oben ragendes langgestrecktes Tragelement aufweist, in dem teleskopierbar ein langgestrecktes Stützelement steckt, an dessen oberen Ende ein Träger befestigt ist, wobei das Stützelement mittels in Rastöffnungen eingreifende Formschlusshalteelemente in verschiedenen Höhenlagen des Trägers am Tragelement fixierbar ist. Beim Stand der Technik werden die Formschlusshalteelemente von Rastzapfen oder von den Gewindeschäften von Schrauben ausgebildet, die in eine von mehreren Öffnungen des Stützelementes eingreifen. Die Schraube bzw. der Rastzapfen muss aus der Öffnung heraus verlagert werden, damit die Rastverbindung zum Zwecke der Vertikalverlagerung des Stützelementes im Tragelement aufgehoben wird.In a preferred embodiment, the holding elements on fixed stops. The fixed stops may have a stop, in particular a pin-shaped stop, which is associated with the first support element. In the position of use can abut against this stop a counter-stop of the other support element. In particular, the counter-stop is formed by a stop table of the flange plate. The fixed stops can absorb the clamping force in the clamping position, which transmits the clamping element on the clamping edge. In a further development of the invention is a locking pin provided, which rests in the locking position in a latching niche. The latching pin may be assigned to the first support element and the latching niche to the second support element, in particular the flange plate. The locking pin can be firmly seated on the actuating member, so that it can be brought together with the clamping element in a displacement of the actuating member of the locking position in a release position. In the release position, the locking pin can slide on pivoting of the two support elements on a guide flank of a guide slot along. The guide flank extends on a circular arc line about the pivot axis about which the two support elements are pivotable. The axis about which the two support elements are pivotable extends transversely to the plane of extent of the flange plate. It extends transversely to the surface extension of two mutually parallel walls of the tubular support element. The pivot axis about which the clamping element is pivotable, however, runs parallel to the surface plane of extension of these two tube walls. The pivoting plane of the clamping element extends in particular transversely to the surface extension of two transverse to the first tube walls second tube walls of a rectangular cross-section having tube, which forms the first support member. In a preferred embodiment of the invention, the second support element extends in the position of use approximately in a horizontal plane. The first support member has at its lower end a first foot. Adjacent to the lower end, the second support element is articulated on the first support element. The free end of the second support element forms a second foot. There are two pairs of legs are provided, each having a first support member and a second support member, so that the support frame has a total of four feet. The two support element pairs are connected to each other via connecting elements. The connecting elements may be rigid traverses, each rigidly interconnecting two first support elements and two second support elements. In which in the use position upwardly extending first support member may be a support element. The further support element can be assigned to be telescopically associated with the first support element. A carrier attached to the end of the further support element can thus be brought to different working heights. The carrier carries in particular in a horizontal plane to each other displaceable jaws that form a workbench surface. A tension member, which may be a pull rod, engages the actuator. A Zugende the tension element is located within the further support element, which has a longitudinal slot through which an end portion of the tension member protrudes from the tubular further support member. There, the tension element is connected to a handle. The handle may be a transverse bar that extends parallel to the connecting elements and on which a user's hand may engage to exert a pull on the pulling element with which the actuating element can be displaced against the restoring force of the spring, to bring the clamping element in the release position to. Along with this, the latching pin is also lifted out of the latching niche so that the second support element, which is a foot element, can be pivoted from the use position to a non-use position. The invention also relates to a development of the locking of the support element in the obliquely upwardly projecting support element. In a further development of the invention is a support frame with an erectable on a base frame, which has at least one obliquely in a vertical plane upwardly projecting elongated support member in the telescopically inserted an elongated support member, at the upper end of a support is fixed, wherein the support element can be fixed by means engaging in detent openings form-fitting retaining elements in different heights of the wearer on the support element. In the prior art, the form-fitting retaining elements of locking pins or of the threaded shafts of screws are formed, which in one of a plurality of openings of the support element intervention. The screw or the locking pin must be displaced out of the opening, so that the latching connection is canceled for the purpose of vertical displacement of the support element in the support element.
Der Erfindung liegt die Aufgabe zugrunde, das Tragegestell gebrauchsvorteilhaft weiterzubilden. Zur Lösung der Aufgabe wird vorgeschlagen, dass dieses Formschlusshalteelement durch eine Schwenkbewegung des Stützelementes gegenüber dem Tragelement in und außer Eingriff in die Rastöffnung bringbar ist. Das Formschlusshalteelement kann hakenartig in die Öffnung eingreifen. Dies hat zur Folge, dass das Stützelement vor der Schwenkbewegung zunächst geringfügig vertikal aufwärts verlagert werden muss, damit der Hakeneingriff gelöst wird. Insofern wird die Rastverbindung durch eine Hub-/Schwenk-Bewegung aufgehoben. Zur Ermöglichung der Schwenkbewegung steckt das Stützelement mit seitlichem Spiel im Tragelement. Das Tragelement kann ein Rechteckrohr sein, in dem ein als Rechteckrohr ausgebildetes Stützelement steckt. Die Öffnung, in die das Formschlusshalteelement eingreift, kann einer Schmalseitenwand des Rechteckrohres zugeordnet sein. Dementsprechend ist auch das Formschlusshalteelement einer Schmalseitenwand des einen rechteckigen Grundriss aufweisenden Tragelements zugeordnet. Die beiden voneinander wegweisenden Schmalseiten des Tragelementes besitzen einen Abstand voneinander, der größer ist, als der Abstand der beiden nach außen weisenden Schmalseitenebenen des Stützelementes. Das Stützelement kann sich innerhalb der Rohrhöhlung des Trageelementes so weit bewegen, dass das Formschlusshalteelement aus der Rastöffnung heraustreten kann. Das Formschlusshalteelement ist bevorzugt der im schräg stehenden Zustand nach unten weisenden Schmalseite des Tragelementes zugeordnet. An dem in der Rohrhöhlung des Tragelementes steckenden Ende des Stützelementes befindet sich ein Stütznocken, der über die Breitseitenfläche des Stützelementes übersteht, die den Rastöffnungen gegenüber liegt. Das Formschlusshalteelement ist unmittelbar neben dem Öffnungsrand der Rohröffnung des Halteelementes angeordnet. Die dem Stütznocken gegenüberliegende Seitenwand des Stützelementes stützt sich am Rand der Rohröffnung des Tragelementes ab. Auf Grund der Schräglage von Stützelement und Tragelement baut sich schwerkraftverursacht ein Drehmoment auf. Als Folge dieses schwerkraftverursachten Drehmomentes stützt sich der Stütznocken an der Innenwandung des Tragelementes ab. Der Überstand des Stütznockens gegenüber der ihm zugeordneten Seitenwandung des Stützelementes entspricht in etwa dem Schwenkbewegungsspiel des Stützelementes im Bereich des Formschlusshalteelementes, so dass im verrasteten Zustand die die Öffnungen aufweisende Seitenwand des Stützelementes im Wesentlichen parallel und bevorzugt in flächiger Anlage zur Innenseitenwand des Tragelementes verläuft. Das Formschlusshalteelement kann vom Kopf einer Senkkopfschraube ausgebildet sein. Die Senkkopfschraube ist in eine Einschrauböffnung des Tragelementes eingeschraubt. Der Durchmesser der Einschrauböffnung ist nur wenig größer als der Durchmesser des Gewindeschaftes der Senkkopfschraube. Der Senkkopf steht somit über die Innenwandung des Tragelementes vor und bildet eine schräge Raststufe. Außenseitig ist auf den Schaft der Senckopfschraube eine Mutter aufgeschraubt.The invention has for its object to further develop the support frame nutzsvorteilhaft. To solve the problem it is proposed that this positive engagement holding element can be brought into and out of engagement with the latching opening by a pivoting movement of the support element relative to the support element. The positive locking element can hook-like engage in the opening. This has the consequence that the support element must first be moved slightly vertically upwards before the pivoting movement, so that the hook engagement is released. In this respect, the locking connection is canceled by a lifting / pivoting movement. To enable the pivoting movement, the support element with lateral play in the support element. The support member may be a rectangular tube, in which a designed as a rectangular tube support element inserted. The opening into which the form-fitting retaining element engages may be associated with a narrow side wall of the rectangular tube. Accordingly, the form-fitting retaining element is associated with a narrow side wall of the support element having a rectangular outline. The two facing away from each other narrow sides of the support element have a distance from each other, which is greater than the distance between the two outwardly facing narrow side planes of the support element. The support member can move so far within the tube cavity of the support member that the positive locking member can emerge from the detent opening. The form-fitting retaining element is preferably assigned to the narrow side of the support element facing downwards in the inclined state. At the end of the support element in the tube cavity of the support element is a support cam, which projects beyond the broad side surface of the support element, which lies opposite the latching openings. The form-fitting retaining element is arranged directly next to the opening edge of the pipe opening of the holding element. The the support cam opposite side wall of the support element is supported on the edge of the pipe opening of the support element. Due to the inclined position of the support element and the support element, a torque builds up due to gravity. As a result of this gravitational torque, the support cam is supported on the inner wall of the support element. The projection of the support cam relative to its associated side wall of the support element corresponds approximately to the pivoting movement of the support element in the region of the form-locking element, so that in the latched state, the openings having side wall of the support element is substantially parallel and preferably in planar contact with the inner side wall of the support element. The positive locking member may be formed by the head of a countersunk screw. The countersunk screw is screwed into a screw-in opening of the support element. The diameter of the screw hole is only slightly larger than the diameter of the threaded shaft of the countersunk screw. The countersunk head thus protrudes beyond the inner wall of the support element and forms an oblique latching step. On the outside, a nut is screwed onto the shaft of the Senckopfschraube.

Der Träger 28 ist ein Spannbackenträger, auf dessen nach oben weisender Seite zwei Spannbacken 29, 30 angeordnet sind, die mittels eines Spindeltriebs aufeinander zu verlagerbar sind. Die Oberseiten der Spannbacken 29, 30 bilden Werkflächen. In den Werkflächen befinden sich Längsschlitze 47, 48. Die Erstreckungsrichtung der Längsschlitze 47, 48 ist quer zu einer Verstellrichtung, in welcher Verstellrichtung die beiden Spannbacken 29, 30 mittels Kurbeln und einem Spindeltrieb aufeinander zu verlagert werden können. Die Spannbacke 29 ist sowohl in Vertikalrichtung, als auch in Horizontalrichtung fest mit dem Träger 28 verbunden. Die Spannbacke 30 ist in Horizontalrichtung fest mit dem Träger 28 verbunden, jedoch durch Betätigen des Spindeltriebes gegenüber der festen Spannbacke 29 verlagerbar. Als Folge dessen verlagert sich auch der Abstand der Längsschlitze 48 der Spannbacke 30 zu den Längsschlitzen 47 der Spannbacke 29.The
In den Spannbacken 29, 30 sind mehrere in einer Richtung quer zur Verstellrichtung nebeneinander liegende Längsschlitze 47, 48 und mehrere in Verstellrichtung nebeneinander liegende Längsschlitze 47, 48 vorgesehen. Die von Langlöchern gebildeten Längsschlitze erstrecken sich quer zur Verstellrichtung und dienen der Befestigung von Werkzeugaufnahmeplatten. Eine derartige Werkzeugaufnahmeplatte kann bspw. mit vier Schrauben an der Werkfläche befestigt werden, wobei jeweils zwei Schrauben in zwei Längsschlitze 47 der Spannbacke 29 und zwei weitere Schrauben in zwei Längsschlitze 48 der Spannbacke 30 eingreifen. Ein Elektromotor bzw. ein elektromotorisch angetriebenes Werkzeug, welches an der mit den Spannbacken verschraubten Befestigungsplatte befestigt ist, befindet sich dann zwischen den beiden Spannbacken 29, 30.In the clamping

Am zweiten Tragelement 2 ist eine Flanschplatte 11 befestigt. Die Flanschplatte 11 besitzt eine Breitseitenfläche, die an einer Breitseitenfläche des Vierkantrohres 1 anliegt. Die Breitseitenfläche des Vierkantrohres 1 besitzt ein erstes schlitzförmiges Fenster 13 und ein zweites schlitzförmiges Fenster 14. Durch das erste schlitzförmige Fenster 13 ragt der Kopf eines Klemmelementes 6 heraus. Bei dem Klemmelement 6 handelt es sich um einen Klemmhebel, der um eine Schwenkachse 16 schwenkbar am ersten Tragelement 1 gelagert ist. Der Klemmhebel 6 lässt sich von einer Verriegelungsstellung, die in der

Das erste Tragelement 1 bildet ein Vierkantrohr aus, mit zwei ersten parallel zueinander verlaufenden Seitenwänden, zu denen die Schwenkachse 3 in Querrichtung verläuft. Zwei zweite Breitseitenflächen des ersten Tragelementes erstrecken sich quer zu den ersten Breitseitenflächen. Quer zu den zweiten Breitseitenflächen erstreckt sich die Schwenkachse 16, um die das Klemmelement schwenkbar ist. Die beiden Schwenkachsen 3, 16 sind in Erstreckungsrichtung des ersten Tragelementes voneinander beabstandet.The
Innerhalb der Höhlung des ersten Tragelementes 1 befindet sich ein Betätigungsglied 18. Das Betätigungsglied 18 besitzt zwei seitlich abragende Flügel 23, 23', die mit Bewegungsspiel an den Innenflächen der beiden kürzeren Seitenflächen des Tragelementes 1 anliegen können. Eine dieser kürzeren Seitenwände ist Trägerin der Schwenkachse 16 des Klemmelementes 6.Within the cavity of the
Das Betätigungsglied 18 trägt einen Rastzapfen 4, der aus dem Fenster 14 aus der Höhlung des ersten Tragelementes herausragt. In der in den Zeichnungen dargestellten Gebrauchsstellung des Tragegestells liegt der Rastzapfen 4 in einer Rastnische 5 der Flanschplatte 11. An die Rastnische 5 schließt sich eine auf einer Kreisbogenlinie um die Schwenkachse 3 verlaufende Führungsflanke 12' an, die von der Randkante eines bogenförmigen Führungsschlitzes 12 gebildet ist.The actuator 18 carries a
Die Schwenkachse 3 durchgreift ein Widerlager 39, welches sich innerhalb des ersten Tragelementes 1 befindet. Sie fesselt das Widerlager 39 an das erste Tragelement. Am Widerlager 39 ist ein Ende einer Zugfeder 25 befestigt. Das andere Ende der Zugfeder 25 ist am Betätigungsglied 18 befestigt. Die Zugfeder 25 beaufschlagt das Betätigungsglied 18 derart, dass der Rastzapfen 4 in der Rastnische 5 gehalten ist. Am Betätigungsglied 18 greift eine Zugstange 26 an, die sich durch die Rohrhöhlung des ersten Tragelementes 1 hindurch bis in die Rohrhöhlung des Stützelementes 27 erstreckt, wo ein Betätigungsende der Zugstange 26 durch einen Schlitz 32, der sich in Erstreckungsrichtung des Stützelementes 27 erstreckt, aus der Höhlung des Stützelementes 27 herausragt. Daran ist eine Handhabe 31 befestigt, die sich parallel zu dem Verbindungselement 38 erstreckt. Wird die Handhabe 31 nach oben gezogen, so verlagert sich das Betätigungsglied 18 ebenfalls nach oben, so dass der Rastzapfen 4 aus der Rastnische 5 heraustritt. Dies erfolgt gegen die Rückstellkraft der Feder 25. Das Widerlager 39 besitzt eine seitliche Ausnehmung, in der eine Buchse 41 eingreift. Die Buchse 41 durchgreift eine Öffnung der Wandung des Tragelementes 1 und eine Öffnung der Flanschplatte 11. Ein Stirnrand der Buchse 41 stützt sich an der Außenseite des zweiten Tragelementes 2 ab. Die Öffnung 42 der Wandung des ersten Tragelementes 1 umgibt im Wesentlichen passgenau die Außenwandung der Buchse 41, durch die die Schwenkachse 3 verläuft.The
Zwischen der Außenwandung des Tragelementes 1 und der Flanschplatte 11 befindet sich eine Passscheibe 43, die die Flanschplatte 11 geringfügig von der Außenwandung des Tragelementes 1 beabstandet hält.Between the outer wall of the
Der Flügel 23 des Betätigungsgliedes 18 besitzt ein Fenster 21, welches mit Bewegungsspiel nach oben und unten vom Klemmelement 6 durchgriffen ist. Nimmt das Betätigungsglied 18 seine in den Zeichnungen dargestellte Verriegelungsstellung ein, in der der Rastzapfen 4 in der Rastnische 5 liegt, so wird der lange Hebelarm des Klemmelementes 6 in unmittelbarer Nachbarschaft des Schlitzes 13 innenseitig des Tragelementes 1 von einer Druckflanke 19 des Fensters 21 nach unten durch die Zugkraft der Zugfeder 25 beaufschlagt. Wird das Betätigungsglied 18 nach oben verlagert, so findet zunächst ein Freigang statt, bis die Hubflanke 20 am Klemmelement 6 anschlägt.

Die lichte Öffnung zwischen den beiden Schmalseitenwänden des ersten Tragelementes ist ausreichend größer als der Abstand der Außenseiten der voneinander wegweisenden Schmalseiten 27', 27" des Stützelementes 27, damit das Stützelement 27 durch eine Schwenkbewegung in und außer Eingriff einer Formschlussrast mit dem Formschlusshaltemittel 44 bringbar ist. In der Eingriffs stellung greift der Senkkopf 44 in eine von mehreren Öffnungen 45 der Schmalseitenwand 27' ein. Ein Rand der Öffnung 45 liegt dabei auf einem nach oben weisenden Abschnitt des konusförmigen Mantelwandabschnitts des Senkkopfes 44. Durch eine geringfügige Hubbewegung kann der Hakeneingriff aufgehoben werden. Durch die Schwenkbewegung tritt der Schraubenkopf 44 aus der Öffnung 45 heraus, so dass das Stützelement 27 in seiner Erstreckungsrichtung verschoben werden kann. Einhergehend damit ändert sich die Höhenlage des Trägers 28. Durch eine erneute Schwenkbewegung kann der Schraubenkopf 44 in eine andere Öffnung 45 eingehakt werden. Das Schwenkbewegungsspiel ist größer als das Maß des Überstandes des Formschlusshalteelementes 44 über die Innenseite der Seitenwandung des Tragelementes 1. Die
