Abstract

The support leg has an upper and a lower leg part (5 and 6) which can be adjusted from a horizontal position resting on the floor, about a pivot pin (33) into an extended position, in which it is secured by a locking device (2). The latter has a bar-like release (38) which, during the pivoting of the lower leg part (6) from its horizontal into its extended position, is automatically movable into the locking position. The lower leg part (6) is seated non-displaceably on the pivot pin (34). The furniture can be raised without fear of the lower leg part (6) coming free from the locked position by mistake. By means of the release (38), the leg part (6) is perfectly held in its extended position. The support leg is structurally simple in design and consists of few individual parts. <IMAGE>

Description

Die Erfindung betrifft einen höhenverstellbaren Stützfuß für Möbel nach dem Oberbegriff des Anspruches 1.The invention relates to a height-adjustable support foot for furniture according to the preamble of claim 1.

Bei einem bekannten Stützfuß dieser Art (DE-A-26 14 435) weist das untere Fußteil an seinen beiden seitlichen Schenkein Arretierzapfen auf, die in Verriegelungsstellung der Fußteile in nach unten randoffene Ausnehmungen der Schenkel des oberen Fußteiles ragen. Um zu verhindern, daß das untere Fußteil beim Anheben des Tisches aus seiner gestreckten Lage unbeabsichtigt in die horizontale Lage zurückschwenkt, sind zusätzliche Sicherungsteile, wie Wellfederringe, vorgesehen, die die Schenkel bzw. in Verlängerung zu diesen liegende Schwenkarme des unteren Fußteiles unter Vorspannung an den oberen Fußteil anpressen und dadurch einen Reibschluß bewirken. Durch den Reibschluß ist das untere Fußteil am oberen Fußteil gehalten. Um das untere Fußteil in die abgesenkte Lage des Stützfußes zu verschwenken, muß es zunächst nach unten vom oberen Fußteil abgezogen werden, bis die Arretierzapfen aus den zugehörigen Ausnehmungen freikommen. In entsprechender Weise muß das untere Fußteil nach dem Zurückschwenken gegen das obere Fußteil verschoben werden, damit die Arretierzapfen in die Ausnehmungen eingreifen. Es besteht die Gefahr, daß beim Anheben des Tisches das untere Fußteil unbeabsichtigt so weit gegenüber dem oberen Fußteil verschoben wird, daß es von ihm freikommt. Der Tisch kann dann beim Absenken unbeabsichtigt kippen.In a known support foot of this type (DE-A-26 14 435), the lower foot part has on its two lateral legs no locking pins which, in the locked position of the foot parts, project into downwardly open recesses in the legs of the upper foot part. In order to prevent the lower foot section from inadvertently swiveling back into its horizontal position when the table is lifted, additional securing parts, such as wave spring washers, are provided which pretension the legs or the pivot arms of the lower foot section lying in extension to them Press on the upper part of the foot and thereby cause friction. The lower foot part is held on the upper foot part by friction. In order to pivot the lower foot part into the lowered position of the support foot, it must first be pulled down from the upper foot part until the locking pins come free from the associated recesses. In a corresponding manner, the lower foot part must be moved against the upper foot part after pivoting back so that the locking pins engage in the recesses. There is a risk that when the table is lifted the lower foot section is inadvertently shifted as far as the upper foot section will be released from him. The table can then accidentally tip over when lowered.

Der Erfindung liegt die Aufgabe zugrunde, einen Stützfuß dieser Art so auszubilden, daß auf einfache Weise eine sichere Verriegelung der beiden Fußteile bei gestrecktem Stützfuß gewährleistet ist.The invention has for its object to provide a support leg of this type so that a secure locking of the two foot parts is guaranteed with the support leg extended.

Diese Aufgabe wird bei einem Stützfuß der gattungsbildenden Art erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved according to the invention in a support leg of the generic type with the characterizing features of claim 1.

Infolge der erfindungsgemäßen Ausbildung wird der Auslöser der Verriegelung beim Zurückschwenken des unteren Fußteiles in die gestreckte Lage in eine Stellung verschwenkt, in der er das untere Fußteil so verriegelt, daß dieses nicht unbeabsichtigt in die abgeklappte Lage zurückschwenken kann. Da das untere Fußteil gegenüber dem oberen Fußteil nur verschwenken, nicht jedoch verschoben werden kann, ist das untere Fußteil durch den Auslöser zuverlässig verriegelt. Das Möbel kann angehoben werden, ohne daß zu befürchten ist, daß das untere Fußteil versehentlich aus der verriegelten Stellung freikommt. Durch den Auslöser ist das untere Fußteil ohne zusätzliches Sicherungsteil einwandfrei in seiner gestreckten Lage gehalten, so daß der erfindungsgemäße Stützfuß konstruktiv einfach ausgebildet ist und nur aus wenigen Einzelteilen besteht.As a result of the design according to the invention, the trigger of the lock is pivoted when the lower foot part is pivoted back into the extended position into a position in which it locks the lower foot part so that it cannot inadvertently pivot back into the folded position. Since the lower foot section can only pivot relative to the upper foot section, but cannot be moved, the lower foot section is reliably locked by the trigger. The furniture can be lifted without fear that the lower foot part will accidentally come out of the locked position. By the trigger, the lower foot part is held properly in its extended position without an additional securing part, so that the support foot according to the invention is structurally simple and consists of only a few individual parts.

Der in den Figuren 1 bis 8 dargestellte Stützfuß 1 dient zur Abstützung einer (nicht dargestellten) Tischplatte eines Klapptisches für einen Wohnwagen oder einen Caravan. Die Tischplatte ist auf einer Befestigungsplatte 4 des Stützfüßes 1 verschraubt, die auf einem oberen Fußteil 5 des zweiteilig ausgebildeten Stützfußes 1 befestigt, vorzugsweise verschweißt ist. Das Fußteil 5 ist mit einem zweiten Fußteil 6 gelenkig verbunden. In der abgesenkten Stellung der Tischplatte gemäß den Figuren 1 und 7 des Stützfußes liegen die Fußteile 5 und 6 senkrecht zueinander, während sie in einer angehobenen, oberen Stellung der Tischplatte miteinander fluchten (Fig. 2 bis 5, 8). In dieser Lage sind die Fußteile 5, 6 über eine Verriegelung 2 gegen Verschwenken gesichert.The support leg 1 shown in Figures 1 to 8 serves to support a table top (not shown) of a folding table for a caravan or caravan. The table top is screwed to a mounting plate 4 of the support foot 1, which is fastened, preferably welded, to an upper foot part 5 of the two-part support foot 1. The foot part 5 is articulated to a second foot part 6. In the lowered position of the table top according to FIGS. 1 and 7 of the supporting foot, the foot parts 5 and 6 are perpendicular to one another, while they are aligned with one another in a raised, upper position of the table top (FIGS. 2 to 5, 8). In this position, the foot parts 5, 6 are secured against pivoting via a lock 2.

Die Fußteile 5, 6 sind durch Metallprofilteile mit U-förmigem Querschnitt gebildet, können aber auch geschlossene Profilteile sein. Der Boden 7, 8 der Fußteile 5, 6 ist zur Versteifung mit einer im wesentlichen über seine ganze Länge und Breite sich erstreckenden Ausprägung 9, 10 vesehen (Fig.1, 7, 8). Die Schenkel 5a, 5b bzw. 6a, 6b der Fußteile 5, 6 sind etwa gleich breit und um ein Mehrfaches schmaler als der Boden 7 und 8. Die vom Fußteil 6 abgewandten Enden 11, 12 der Schenkel 5a, 5b des Fußteiles 5 sind mit der Befestigungsplatte 4 vorzugsweise verschweißt. Sie sind vorzugsweise (nicht dargestellt) rechtwinklig abgebogen, so daß die Platte 4 auf den Schenkelenden 11, 12 flächig aufliegt. Die anderen Schenkelenden 13, 14 des Fußteiles 5 (Fig. 5, 7) sind gerade ausgebildet. Auf dem dem Fußteil 6 zugewandten Ende des Fußteiles 5 sitzt ein Abdeckteil 17, das weiter unten noch im einzelnen beschrieben wird. Es übergreift das obere Ende des unteren Fußteiles 6 so, daß der Zwischenraum zwischen den Fußteilen bei deren Verschwenken nach außen abgedeckt ist. Dadurch wird verhindert, daß sich die Bedienungsperson beim Verschwenken des unteren Fußteiles 6 durch Einklemmen der Finger verletzen kann. Gleichzeitig dient das Abdeckteil 17 als Stütze oder Auflage, mit der das obere Fußteil 5 bei weggeschwenktem Fußteil 6 am Boden aufliegt (Fig. 1).The foot parts 5, 6 are formed by metal profile parts with a U-shaped cross section, but can also be closed profile parts. The bottom 7, 8 of the foot parts 5, 6 is provided for stiffening with an expression 9, 10 which extends essentially over its entire length and width (FIGS. 1, 7, 8). The legs 5a, 5b and 6a, 6b of the foot parts 5, 6 are approximately the same width and several times narrower than the bottom 7 and 8. The ends 11, 12 of the legs 5a, 5b of the foot part 5 facing away from the foot part 6 are included the mounting plate 4 is preferably welded. They are preferably bent (not shown) at right angles, so that the plate 4 lies flat on the leg ends 11, 12. The other leg ends 13, 14 of the foot part 5 (Fig. 5, 7) are straight. On the end of the foot part 5 facing the foot part 6 there is a cover part 17, which will be described in more detail below. It overlaps the upper end of the lower foot part 6 so that the space between the foot parts is covered when they are pivoted outwards. This prevents the operator from pivoting the lower foot part 6 can injure by pinching the fingers. At the same time, the cover part 17 serves as a support or support with which the upper foot part 5 rests on the floor when the foot part 6 is pivoted away (FIG. 1).

Das untere freie Ende des Fußteiles 6 ist ebenfalls mit einem kappenartigen Abdeckteil- bzw. Stützteil 19 abgedeckt, das wie das Abdeckteil 17 vorzugsweise aus Kunststoff besteht. Es kann aber auch aus Metall hergestellt sein. Das Abdeckteil 19 hat einen u-förmig verlaufenden Rand 21 (Fig. 1), in den das Fußteil 6 mit seinem unteren Rand gesteckt ist. Das Abdeckteil 19 hat ferner einen Boden 20, an den der Rand 21 anschließt. Mit dem Boden 20 stützt sich das Fußteil 6 bei gestrecktem Stützfuß am Boden des Fahrzeuges ab. Das Abdeckteil 17 hat ähnliche Form wie das Abdeckteil 19; es hat ebenfalls einen u-förmig umlaufenden Rand 22 (Fig 1 und 5 bis 7), mit dem es das zugehörige Ende des Fußteiles 5 umgreift (Fig. 4, 8). Außerdem weist das Abdeckteil 17 einen zum Rand 22 senkrechten Boden 24 auf, dessen Breite etwa gleich der Höhe des Randes 22 ist. Bei gestrecktem Stützfuß 1 liegt der Boden 24 des Abdeckteiles 17 mit nur geringem Abstand zum stirnseitigen Rand 25 des Bodens 8 des Fußteiles 6 (Fig. 5).The lower free end of the foot part 6 is also covered with a cap-like cover part or support part 19 which, like the cover part 17, is preferably made of plastic. But it can also be made of metal. The cover part 19 has a U-shaped edge 21 (FIG. 1) into which the foot part 6 is inserted with its lower edge. The cover part 19 also has a bottom 20 to which the edge 21 connects. With the floor 20, the foot part 6 is supported on the floor of the vehicle when the support foot is extended. The cover part 17 has a similar shape as the cover part 19; it also has a U-shaped peripheral edge 22 (FIGS. 1 and 5 to 7) with which it engages around the associated end of the foot part 5 (FIGS. 4, 8). In addition, the cover part 17 has a bottom 24 perpendicular to the edge 22, the width of which is approximately equal to the height of the edge 22. When the support foot 1 is stretched, the bottom 24 of the cover part 17 lies only a short distance from the end edge 25 of the bottom 8 of the foot part 6 (FIG. 5).

Wie insbesondere die Fig. 5 und 6 zeigen, hat das Abdeckteil 17 seitliche Durchführschlitze 26, 27 für die Schenkelenden 13, 14 des Fußteiles 5 und die freien Schenkelenden 28, 29 (Fig. 5 und 6) des Fußteiles 6. Die Durchführschlitze 26, 27 durchsetzen den Boden 24 des Abdeckteiles 17 und die Schenkel 30, 31 des U-förmigen Randes 22. Die Schenkel 30, 31 des Randes 22 des Abdeckteiles 17 sind nicht verdeckt ausgebildet, so daß sie durch die Durchführschlitze 26, 27 nicht unzulässig stark geschwächt sind. Die einander zugewandten Bereiche der Randschenkel 30, 31 haben jeweils eine Vertiefung 32, die in die vom Boden 24 abgewandte Stirnseite des Schenkel 30, 31 mündet und die jeweils einen Lagerbolzen 33, 34 aufnehmen (Fig. 4 bis 8), der an den Schenkelenden 13, 14 des Fußteiles 5 vorgesehen ist. Die Bolzen 33, 34 erstrecken sich fluchtend in Richtung zueinander und ragen durch Öffnungen bzw. Bohrungen in den Schenkelenden 28, 29 des Fußteiles 6. Über die Lagerbolzen 33, 34 sind die beiden Fußteile 5, 6 gelenkig miteinander verbunden.5 and 6 in particular, the cover part 17 has lateral through-slots 26, 27 for the leg ends 13, 14 of the foot part 5 and the free leg ends 28, 29 (FIGS. 5 and 6) of the foot part 6. The through-slots 26, 27 penetrate the bottom 24 of the cover part 17 and the legs 30, 31 of the U-shaped edge 22. The legs 30, 31 of the edge 22 of the cover part 17 are not concealed, so that they are not weakened inadmissibly by the through slots 26, 27 are. The areas facing each other the edge legs 30, 31 each have a recess 32 which opens into the end face of the legs 30, 31 facing away from the bottom 24 and which each receive a bearing pin 33, 34 (FIGS. 4 to 8), which on the leg ends 13, 14 of the Foot part 5 is provided. The bolts 33, 34 extend in alignment in the direction of one another and protrude through openings or bores in the leg ends 28, 29 of the foot part 6. The two foot parts 5, 6 are articulated to one another via the bearing bolts 33, 34.

Der Lagerbolzen 33 ragt durch ein in Längsrichtung des Fußteiles 5 sich erstreckendes Langloch 37 (Fig. 5 bis 8) eines Auslösers 38 der Verriegelung 2. Der Auslöser 38 ist riegelartig ausgebildet und mit einer Handhabe 3 der Verriegelung 2 verbunden, wie noch erläutert wird.The bearing pin 33 protrudes through an elongated hole 37 (FIGS. 5 to 8) of a trigger 38 of the locking mechanism 2, which extends in the longitudinal direction of the foot part 5. The trigger mechanism 38 is designed like a bolt and is connected to a handle 3 of the locking mechanism 2, as will be explained below.

Wie die Fig. 4 und 8 zeigen, ragt der Boden 7 des Fußteiles 5 mit seinem dem Fußteil 6 zugewandten Ende 39 in einen Schlitz 40 des Abdeckteiles 17. Die dem Fußteil 6 zugewandten unteren Ränder 41 (Fig. 4) der die Vertiefung 32 aufweisenden Teile der Schenkel 30, 31 des Abdeckteiles 17 sind in ihrer vom Rand 22 abgewandten Hälfte teilkreisförmig abgerundet. Der Boden 24 des Abdeckteiles 17 ist in gleicher Weise gekrümmt ausgebildet wie die Ränder 41, wie durch eine gestrichelte Linie in Fig. 4 angedeutet ist. Der Boden 24 und die Ränder 41 sind um die Achse der Lagerbolzen 33, 34 gekrümmt. Dies hat den Vorteil, daß beim Verschwenken der Fußteile 5, 6 relativ zueinander die Breite des Spaltes 35 zwischen dem Fußteil 6 und dem Boden 24 des Abdeckteiles 17 konstant bleibt. Da die Spaltbreite sehr klein ist, können Finger im Spalt 35 während des Verschwenkens der Fußteile 5, 6 nicht eingeklemmt werden. Das Abdeckteil 17 dient somit nicht nur als Auflage für das Fußteil 5 bei abgewinkeltem Stützfuß 1, sondern auch als Klemmschutz für die Finger.4 and 8 show, the bottom 7 of the foot part 5 protrudes with its end 39 facing the foot part 6 into a slot 40 of the cover part 17. The lower edges 41 (FIG. 4) facing the foot part 6 and having the recess 32 Parts of the legs 30, 31 of the cover part 17 are rounded in a part-circle in their half facing away from the edge 22. The bottom 24 of the cover part 17 is curved in the same way as the edges 41, as indicated by a broken line in FIG. 4. The bottom 24 and the edges 41 are curved around the axis of the bearing bolts 33, 34. This has the advantage that when the foot parts 5, 6 are pivoted relative to one another, the width of the gap 35 between the foot part 6 and the bottom 24 of the cover part 17 remains constant. Since the gap width is very small, fingers can be in the gap 35 during the pivoting of the Foot parts 5, 6 are not pinched. The cover part 17 thus serves not only as a support for the foot part 5 when the support foot 1 is angled, but also as a pinch protection for the fingers.

Der Boden 24 des Abdeckteiles 17 geht im Bereich der Schenkel 30, 31 jeweils über eine Abwinkelung 43 (Fig. 4) in die Schenkel über. Dadurch haben die die Vertiefung 32 aufweisenden Teile der Schenkel 30, 31 jeweils eine Nase 42, die über die äußeren Schenkelteile geringfügig vorsteht.The bottom 24 of the cover part 17 merges into the legs in the region of the legs 30, 31 via an angle 43 (FIG. 4). As a result, the parts of the legs 30, 31 which have the depression 32 each have a nose 42 which projects slightly beyond the outer leg parts.

Wie die Fig. 7 und 8 zeigen, hat der Rand 22 des Abdeckteiles 17 im Bereich der seitlichen Schlitze 26, 27 in einem unteren, an das Ende 39 des Fußteiles 5 anschließenden Abschnitt 44 geringere Wandstärke als im übrigen Bereich. Vorzugsweise ist an der Innenseite des Randes 22 eine U-förmige Ausnehmung 45 gebildet (Fig. 7), in die bei gestrecktem Stützfuß 1 ein Vorsprung 46 der oberen Schenkelenden 28, 29 des Fußteiles 6 ragt. Die beiden Vorsprünge 46 hintergreifen in gestreckter Lage des Stützfußes 1 (Fig. 8) das untere Ende 39 des Fußteiles 5, so daß eine genaue Lageausrichtung der Fußteile zueinander gewährleistet ist.7 and 8 show, the edge 22 of the cover part 17 in the region of the lateral slots 26, 27 in a lower section 44 adjoining the end 39 of the foot part 5 has a smaller wall thickness than in the rest of the region. A U-shaped recess 45 is preferably formed on the inside of the edge 22 (FIG. 7), into which a projection 46 of the upper leg ends 28, 29 of the foot part 6 projects when the support foot 1 is extended. In the extended position of the support foot 1 (FIG. 8), the two projections 46 engage behind the lower end 39 of the foot part 5, so that an exact positional alignment of the foot parts with respect to one another is ensured.

Die Vorsprünge 46 schließen über jeweils eine halbkreisförmige Vertiefung 47 an den oberen Rand 25 des Bodens 8 des Fußteiles 6 an. Die Vorsprünge 46 liegen in der Ebene der Schenkel 6a, 6b des Fußteiles 6 und haben annähernd rechteckigen Umriß mit abgerundeten Kanten. Die Vorsprünge 46 ragen über den dem Boden 8 zugewandten Rand der Schenkel 6a, 6b. Der die Vorsprünge 46 aufweisende Teil 28, 29 der Schenkel 6a, 6b steht über den Boden 8 vor. Die Vorsprünge 46 gehen über jeweils eine halbkreisförmig abgerundete Nase 46a in den mit dem Boden 8 des Fußteiles 6 im wesentlichen fluchtenden rückwärtigen Randabschnitt 48 des zugehörigen Schenkelendes 28, 29 des Fußteiles 6 über. Der Randabschnitt 48 geht abgerundet in einen spitzwinklig zu ihm liegenden Randabschnitt 49 über, der an einen geraden Randabschnitt 50 anschließt. Er ist der freie Rand der Schenkel 6a, 6b des Fußteiles 6.The projections 46 connect via a semicircular depression 47 to the upper edge 25 of the bottom 8 of the foot part 6. The projections 46 lie in the plane of the legs 6a, 6b of the foot part 6 and have an approximately rectangular outline with rounded edges. The projections 46 protrude beyond the edge of the legs 6a, 6b facing the base 8. The part 28, 29 of the legs 6a, 6b which has the projections 46 protrudes above the base 8. The projections 46 each go over a semi-circular rounded nose 46a into the bottom 8 of the foot part 6 essentially aligned rear edge portion 48 of the associated leg end 28, 29 of the foot part 6 via. The edge section 48 merges rounded into an edge section 49 lying at an acute angle to it, which adjoins a straight edge section 50. It is the free edge of the legs 6a, 6b of the foot part 6.

Der Auslöser 38 ist riegelartig ausgebildet und weist etwa in halber Länge eine Stufe 51 auf, so daß ein oberer Riegelteil 52 und ein unterer Riegelteil 60 gebildet sind. Der Riegelteil 52 liegt an der Innenseite des Schenkels 5a des Fußteiles 5 flächig an. Das der Handhabe 3 zugewandte Ende 54 des Riegels 52 ist hakenförmig ausgebildet (Fig. 5) und liegt rechtwinklig zum Riegelteil 53. Das freie Ende 55 des Hakenendes 54 ist stumpfwinklig abgebogen und hat eine Hakenöffnung 56, in der ein Steg 57 eines Federteiles 58 liegt. Es ragt durch eine Öffnung 59 im Schenkel 5a des Fußteiles 5. Der untere Riegelteil 60 liegt an der Innenseite des Schenkels 30 des Abdeckteiles 17 an. In der gestreckten Lage der Fußteile 5, 6 liegt der Lagerbolzen 33 (Fig. 8) am oberen Rand des Langloches 37 des Auslösers 38 an, während er bei abgewinkeltem Stützfuß (Fig. 7) am unteren Ende des Langloches anliegt.The trigger 38 is bar-shaped and has a step 51 approximately in half its length, so that an upper bar part 52 and a lower bar part 60 are formed. The locking part 52 lies flat against the inside of the leg 5a of the foot part 5. The end 54 of the latch 52 facing the handle 3 is hook-shaped (FIG. 5) and lies at right angles to the latch part 53. The free end 55 of the hook end 54 is bent at an obtuse angle and has a hook opening 56 in which a web 57 of a spring part 58 lies . It protrudes through an opening 59 in the leg 5a of the foot part 5. The lower latch part 60 lies against the inside of the leg 30 of the cover part 17. In the extended position of the foot parts 5, 6, the bearing pin 33 (FIG. 8) lies against the upper edge of the elongated hole 37 of the trigger 38, while it rests against the lower end of the elongated hole when the support leg is angled (FIG. 7).

Der Auslöser 38 hat ein unteres, dreieckförmig ausgebildetes Ende 61, mit dem er nach unten über das Fußteil 5 ragt. Bei abgewinkeltem Stützfuß 1 wird das Auslöserende 61 vom Abdeckteil 17 überragt. Dadurch wird verhindert, daß das Riegelende 61 in der Lage des Stützfußes 1 gem. Fig. 7 am Boden aufliegt und dadurch beschädigt wird. In gestreckter Lage der Fußteile 5, 6 liegt der Auslöser 38 mit seinem Ende 61 bzw. seinem rückwärtigen Rand 62 am Boden 8 des Fußteiles 6 an. Das Auslöserende 61 übergreift somit das Fußteil, das dadurch nicht um die Lagerbolzen 33, 34 geschwenkt werden kann.The trigger 38 has a lower, triangular end 61 with which it projects downward over the foot part 5. When the support foot 1 is angled, the trigger end 61 is surmounted by the cover part 17. This prevents the bolt end 61 according to the position of the support foot 1. Fig. 7 rests on the floor and is damaged. In the extended position of the foot parts 5, 6, the trigger 38 abuts the bottom 8 of the foot part 6 with its end 61 or its rear edge 62. The trigger end 61 overlaps thus the foot part, which cannot be pivoted about the bearing bolts 33, 34 as a result.

Zum Verschwenken des Fußteiles 6 aus der gestreckten in die abgewinkelte Lage muß der Auslöser 38 durch Betätigen der Handhabe 3 nach oben in Richtung des Pfeiles P in den Fig. 5 und 7 verschoben werden. Dadurch wird über das Hakenende 54, 55 der Auslöser 38 in gleicher Richtung in die in Fig. 7 dargestellte Lage verschoben. Das Ende 61 des Auslösers 38 liegt in der nach oben verschobenen Endstellung oberhalb des Randes 25 des Fußteiles 6, so daß es in die in Fig. 7 dargestellte Lage verschwenkt werden kann.To pivot the foot part 6 from the extended into the angled position, the trigger 38 must be moved upwards in the direction of arrow P in FIGS. 5 and 7 by actuating the handle 3. As a result, the trigger 38 is displaced in the same direction into the position shown in FIG. 7 via the hook end 54, 55. The end 61 of the trigger 38 lies in the upwardly displaced end position above the edge 25 of the foot part 6, so that it can be pivoted into the position shown in FIG. 7.

Die Handhabe 3 hat einen in Seitenansicht gem. Fig. 1 und 5 dreieckförmigen Grundkörper 3a, der in Draufsicht auf den Schenkel 5a des Fußes 5 rechteckigen Umriß hat (Fig. 2) und auf der Außenseite des Schenkels 5a des Fußteiles 5 liegt. Der Grundkörper 3a weist einen nach unten ragenden Steg 63 auf, mit dem er an der Außenseite des Schenkels 5a des Fußteiles 5 geführt wird. Der Steg 63 verläuft senkrecht zu der einen kürzeren Dreiecksseite 64 des Grundkörpers 3a und bildet mit dessen Grundseite 65 eine gemeinsame Führungsfläche. Der Grundkörper 3a ist nahezu über seine ganze Höhe mit einem in Längsrichtung sich erstreckenden Schlitz 66 versehen, in den ein freies, abgewinkeltes Ende 67 eines längeren Schenkels 68 des Federteiles 58 ragt. Das abgewinkelte Schenkelende 67 liegt vorteilhaft unter elastischer Vorspannung am oberen Rand 59a der Öffnung 59 an (Fig. 5). Das im wesentlichen U-förmige Federteil 58 bzw. seine Schenkel haben geringfügig kleinere Breite als der Schlitz 66. Der längere Schenkel 68 des Federteiles 58 geht etwa rechtwinklig in den Steg 57 über, der spitzwinklig an einen kurzen und zum Steg 63 parallelen Schenkel anschließt. Er geht senkrecht in einen verdeckten Übergangsabschnitt 70 über, der eine dachförmige Außenfläche 71 aufweist. Sie schließt an eine zum Schenkel 5a stumpfwinklig verlaufende Bodenfläche 72 des Längsschlitzes 66 an. Vorzugsweise besteht die Handhabe 3 aus Kunststoff. Der Federteil 58 bzw. sein längerer Schenkel 68 sind elastisch federnd ausgebildet. Wird die Handhabe 3 zum Wegschwenken des unteren Fußteiles 6 nach oben in Richtung des Pfeiles P geschoben, dann wird der Grundkörper 3a mit dem Steg 63 und dem Übergangsabschnitt 70 relativ zum Federschenkel 68 verschoben, der sich mit seinem freien Ende 67 am Öffnungsrand 59a abstützt. Dabei wird der Federschenkel 68 elastisch gebogen. Der Grundkörper 3a kann maximal so weit verschoben werden, bis der Federschenkel 68 an der Bodenfläche 71 zur Anlage kommt. Der Übergangsabschnitt 70 verleiht der Handhabe 3 eine hohe Festigkeit. Sobald das Fußteil 6 weggeschwenkt worden ist, kann die Handhabe 3 freigegeben werden. Unter der Kraft des Federschenkels 68 wird der Grundkörper 3a wieder in seine Ausgangslage gem. Fig. 5 zurückgeschoben. Der Grundkörper 3a liegt dann unter der Kraft des vorgespannten Federschenkels 68 am unteren Öffnungsrand 59b an.The handle 3 has a side view acc. 1 and 5 triangular base body 3a, which has a rectangular outline in plan view of the leg 5a of the foot 5 (FIG. 2) and is located on the outside of the leg 5a of the foot part 5. The base body 3a has a web 63 which projects downwards and with which it is guided on the outside of the leg 5a of the foot part 5. The web 63 extends perpendicular to the one shorter triangular side 64 of the base body 3a and forms a common guide surface with the base side 65 thereof. The main body 3a is provided with a slot 66 extending in the longitudinal direction over almost its entire height, into which a free, angled end 67 of a longer leg 68 of the spring part 58 protrudes. The angled leg end 67 advantageously rests under elastic prestress on the upper edge 59a of the opening 59 (FIG. 5). The essentially U-shaped spring part 58 or its legs have a slightly smaller width than the slot 66. The longer leg 68 of the spring part 58 merges approximately at right angles into the web 57, which connects at an acute angle to a short leg parallel to the web 63. It merges vertically into a covered transition section 70, which has a roof-shaped outer surface 71. It adjoins a bottom surface 72 of the longitudinal slot 66 which is at an obtuse angle to the leg 5a. The handle 3 is preferably made of plastic. The spring part 58 or its longer leg 68 are elastically resilient. If the handle 3 is pushed upwards in the direction of arrow P to pivot the lower foot part 6, then the base body 3a with the web 63 and the transition section 70 is displaced relative to the spring leg 68, which is supported with its free end 67 on the opening edge 59a. The spring leg 68 is bent elastically. The base body 3a can be displaced at most until the spring leg 68 comes to rest on the bottom surface 71. The transition section 70 gives the handle 3 high strength. As soon as the foot part 6 has been pivoted away, the handle 3 can be released. Under the force of the spring leg 68, the base body 3a is returned to its original position. Fig. 5 pushed back. The base body 3a then bears against the lower opening edge 59b under the force of the prestressed spring leg 68.

Entsprechend einfach läßt sich der Fußteil 6 bei angehobenem Tisch in Richtung des Pfeiles Z in Fig. 7 in die gestreckte Lage zurückschwenken. Hierbei gelangt der Fußteil 6 mit seinem oberen Rand 25 am Riegelende 61 zur Anlage. Es hat einen schräg zum Schwenkweg Z des Randes 25 des Bodens 8 des Fußteiles 6 liegenden Auflaufrand 74. Sobald der Stirnrand 25 am Auflaufrand 74 zur Anlage kommt, wird der Auslöser 38 zusammen mit dem Grundkörper 3a gegen die Kraft des Federschenkels 68 beim Verschwenken des Fußteiles 6 verschoben. Sobald der Rand 25 des Fußteiles 6 das Riegelende 61 passiert hat, wird der Auslöser 38 selbsttätig unter der Kraft des Federschenkels 68 in die Verriegelungsstellung gem. Fig. 8 verstellt. Vorzugsweise hat das Riegelende 61 eine abgerundete Spitze, so daß der Rand 25 des Fußteiles 6 leicht über den Auslöser 38 hinweggeschwenkt werden kann.Correspondingly simple, the foot part 6 can be pivoted back into the extended position in the direction of arrow Z in FIG. 7 with the table raised. Here, the foot part 6 comes to rest with its upper edge 25 on the locking end 61. It has an overrun edge 74 lying obliquely to the swivel path Z of the edge 25 of the base 8 of the foot part 6. As soon as the end edge 25 comes into contact with the overflow edge 74, the trigger 38 together with the base body 3a acts against the force of the spring leg 68 when the foot part is pivoted 6 postponed. As soon as the edge 25 of the foot part 6 has passed the locking end 61, the trigger 38 becomes automatic under the force of the spring leg 68 in the locking position acc. Fig. 8 adjusted. The locking end 61 preferably has a rounded tip, so that the edge 25 of the foot part 6 can be pivoted easily over the trigger 38.
