Abstract

Each tabletop part (2) can be displaced parallel along curved control path relative to an extension axis (6) which is common to both plate parts (2) so that the dividing edge (2a) of each plate part is aligned over the entire path of movement always at right angles to the common axis which is room-fixed. The plate parts are each movable by a parallelogram guide (7,8,10) and both guides are connected together by synchronized coupling so that the two plate parts move simultaneously by the same amounts. The stationary bearings points of the parallelogram guides lie on the common extension axis

Description

Die Erfindung betrifft einen Ausziehtisch mit zwei Plattenteilen, die auf einem Traggestell gelagert und in einer gemeinsamen Ausziehebene zwischen einer Ruheposition, in der die Trennkanten der beiden Plattenteile aneinander anliegen, und einer Ausziehposition, in der die Trennkanten zueinander beabstandet sind, beweglich sind.The invention relates to an extension table with two plate parts, which are stored on a support frame and in a common Extending level between a rest position in which the separating edges of the two plate parts lie against each other, and a pull-out position in which the separating edges to each other are spaced, are movable.

Solche Ausziehtische sind allgemein bekannt. Zur Vergrößerung der Tischoberfläche werden dazu die beiden am Tischsockel linearbeweglich gelagerten Plattenteile auseinandergezogen und in den entstehenden Freiraum ein zusätzlicher Plattenteil eingefügt. Um jeden Plattenteil für sich ausziehen zu können, sind relativ platzraubende Führungsschienen zwischen Tischsockel und Plattenteilen vorgesehen.Such extending tables are generally known. For enlargement the table surface, the two on the table base become linearly movable stored plate parts pulled apart and an additional plate part in the resulting free space inserted. In order to be able to pull out each plate part for yourself, are relatively space-consuming guide rails between the table base and plate parts provided.

Da die relativ aufwendige Bauweise solcher Ausziehtische bei Glastischen in ästhetischer Hinsicht Nachteile aufweist, ist es auch bekannt (DE 87 09 579 U1), bei einem Glastisch an den Unterseiten der Glasplattenteile Halter anzukleben, mittels derer die Glasplattenteile auf Führungsschienen des Traggestells des Ausziehtisches abgestützt sind. Die Länge der Führungsschienen erfordert die Lagerung dieser Führungsschienen an einem Tragrahmen, der relativ viel Raum beansprucht. Because the relatively complex construction of such extending tables Glass tables has disadvantages from an aesthetic point of view it also known (DE 87 09 579 U1), at a glass table to the Glue the underside of the glass plate parts to the holder using which the glass plate parts on guide rails of the support frame of the extending table are supported. The length of the guide rails requires the storage of these guide rails on a support frame that takes up a relatively large amount of space.

Aus der DE 41 35 912 C2 ist ein Schwenktisch bekannt, bei dem die Plattenteile auf verschwenkbaren Tragarmen gehalten sind. Die Tragarme wiederum sind an einem Traggestell in Form eines Sockels gelagert. Zum Verändern der Tischgröße benötigt dieser Schwenktisch jedoch einen relativ großen Freiraum, da die Plattenteile beim Ein- oder Ausschwenken eine große Fläche im Raum überstreichen, die freigehalten werden muß. Das Verändern der Tischgröße gestaltet sich dadurch relativ aufwendig, da der Tisch zum einen so weit in der Mitte eines Raumes plaziert sein muß, daß die entsprechenden Schwenkbewegungen der Plattenteile möglich sind. Zum anderen müssen auch Stühle oder andere Arten von Sitzgelegenheiten so weit von dem Schwenktisch entfernt werden, daß sie beim Ein- oder Ausschwenken der Plattenteile deren Bewegungsbahn nicht kreuzen und damit blockieren. Insbesondere bei beengten Raumverhältnissen ist unter Umständen eine Tischvergrößerung, sofern es sich um längliche Tischflächen handelt, gar nicht möglich.From DE 41 35 912 C2 a swivel table is known in which the plate parts are held on pivotable support arms. The support arms are in turn in the form of a support frame Base stored. To change the table size you need this However, the swivel table has a relatively large amount of free space because the Plate parts when swiveling in or out a large area in the Cover space that must be kept clear. The changing the table size is therefore relatively complex, because the table is placed so far in the middle of a room must be that the corresponding pivoting movements of the Plate parts are possible. On the other hand also chairs or other types of seating so far from that Swing table be removed that they when swiveling in or out of the plate parts do not cross their path of movement and block with it. Especially in confined spaces may be an enlargement of a table, provided it it is elongated table tops, not possible at all.

Aufgabe der Erfindung ist es daher, einen Ausziehtisch der eingangs genannten Art zu schaffen, der zum einen eine Vielzahl von Gestaltungsmöglichkeiten gestattet und zum anderen auch bei beengten Raumverhältnissen mit geringem Aufwand in seiner Größe veränderbar ist.The object of the invention is therefore an extension table to create a variety of design options allowed and on the other even in confined spaces with little effort its size is changeable.

Diese Aufgabe wird dadurch gelöst, daß jeder Plattenteil entlang jeweils einer gekrümmten Aussteuerbahn derart relativ zu einer beiden Plattenteilen gemeinsamen raumfesten Ausziehachse parallelverlagerbar ist, daß die Trennkante jedes Plattenteiles über die gesamte Bewegungsbahn immer rechtwinklig zu der gemeinsamen raumfesten Ausziehachse ausgerichtet ist. Durch die erfindungsgemäße Lösung wird eine äußerst einfache Ausziehführung für die Plattenteile geschaffen, die insbesondere für die Lagerung am Traggestell des Ausziehtisches, beispielsweise an einem Sockel, einen relativ geringen Bauraum benötigt. Dadurch ist der Ausziehtisch aufgrund der kompakten funktionalen Bauteile vom Design her weitgehend frei gestaltbar. Da die Plattenteile entlang einer einzelnen, gemeinsamen Ausziehachse parallelverlagert werden, ohne daß sie beim Ausziehen oder beim Zusammenschieben eine größere Fläche im Raum überstreichen, ist die Veränderung der Tischgröße auch bei relativ begrenztem seitlichen Raumangebot ohne weiteres möglich. Die einfache Gestaltung der Ausziehfunktion gestattet insbesondere auch die Gestaltung der Plattenteile aus einem transparentem Material, beispielsweise Glas.This object is achieved in that each plate part along each relative to a curved actuation track a spatially fixed pull-out axis common to both plate parts is parallel displaceable that the separating edge of each plate part Always at right angles over the entire trajectory the common fixed extension axis is aligned. The solution according to the invention makes it extremely simple Pull-out guide created for the plate parts, in particular for storage on the support frame of the extending table, for example on a base, a relatively small space needed. This makes the extendable table compact Functional components can be largely freely designed. Because the plate parts along a single, common Pull-out axis can be moved in parallel without being pulled out or when pushing together a larger area in the room paint over, the change in table size is also included relatively limited lateral space is easily possible. The simple design of the pull-out function allows especially the design of the plate parts from one transparent material, such as glass.

In Ausgestaltung der Erfindung sind die Plattenteile mittels jeweils einer Parallelogrammführung beweglich gelagert. Dadurch sind die Plattenteile jeweils um wenigstens zwei Drehpunkte drehbar gelagert. Durch diese Ausgestaltung ergibt sich eine besonders einfach aufgebaute und kostengünstige Parallelverlagerung für die Plattenteile. Durch die Lagerung der Plattenteile mithilfe von Parallelogrammführungen ergibt sich für die Plattenteile eine Aussteuerbahn in Form einer kreisbogenförmigen Bahnkurve.In an embodiment of the invention, the plate parts are by means of one parallelogram guide is movably mounted. Thereby are the plate parts each around at least two pivot points rotatably mounted. This configuration results a particularly simple and inexpensive Parallel displacement for the plate parts. By storage of the plate parts using parallelogram guides a control track in the form of a circular arc trajectory.

In weiterer Ausgestaltung sind die beiden Parallelogrammführungen mittels einer Synchronkopplung derart miteinander verbunden, daß beide Plattenteile gleichzeitig um gleiche Beträge beweglich sind. Durch die Synchronkopplung ist es möglich, durch eine Bedienung lediglich eines Plattenteiles gleichzeitig beide Plattenteile auseinanderzuziehen oder zusammenzuschieben.In a further embodiment, the two parallelogram guides connected to one another by means of a synchronous coupling, that both plate parts at the same time by equal amounts are mobile. The synchronous coupling makes it possible by operating only one plate part at a time to pull apart or push both plate parts together.

In weiterer Ausgestaltung der Erfindung liegen die stationären Lagerpunkte beider Parallelogrammführungen auf der gemeinsamen Ausziehachse. Dadurch wird gewährleistet, daß die Parallelogrammführungen räumlich kompakt auf dem Traggestell angeordnet sind.In a further embodiment of the invention, the stationary Bearing points of both parallelogram guides on the common one Extension axis. This ensures that the Parallelogram guides spatially compact on the support frame are arranged.

In weiterer Ausgestaltung der Erfindung liegen die beiden Parallelogrammführungen einander punktsymmetrisch zu einer vertikalen Mittelachse des Traggestells gegenüber, und als Synchronkopplung sind die beiden um die vertikale Mittelachse gelagerten und miteinander fluchtenden Parallelogrammlenker der gegenüberliegenden Parallelogrammführungen zu einer um die Mittelachse drehbaren Quertraverse einstückig miteinander verbunden. Dadurch wird eine besonders günstige Anordnung der Parallelogrammführungen erzielt, die einen weiter verringerten Bauraum benötigt. Durch die die beiden Parallelogrammführungen einstückig miteinander verbindende Quertraverse wird zudem eine äußerst einfache und dennoch funktionssichere Synchronkopplung geschaffen. Die Anordnung der Parallelogrammführungen sowie der Quertraverse symmetrisch zu der vertikalen Mittelachse gestattet den Einsatz des Traggestells für den Ausziehtisch in Form eines zentralen Tischsockels. Dadurch sind sowohl für den Tischsockel als auch für Form- und Materialwahl der Plattenteile vielfältige Gestaltungsmöglichkeiten gegeben.In a further embodiment of the invention, the two lie Parallelogram guides point symmetrically to one another vertical center axis of the support frame opposite, and as Synchronous coupling are the two around the vertical central axis mounted and aligned parallelogram handlebars of the opposite parallelogram guides to one the central axis rotatable cross member in one piece connected. This results in a particularly favorable arrangement of the Parallelogram guides achieved that further reduced Installation space required. Through the two parallelogram guides cross-piece connected in one piece will also be an extremely simple yet reliable function Synchronous coupling created. The arrangement of the parallelogram guides and the crossbar symmetrical to the vertical center axis allows the use of the support frame for the extending table in the form of a central table base. This means that both for the table base and for shape and Choice of materials for the panel parts given.

In weiterer Ausgestaltung der Erfindung ist die Quertraverse an dem Traggestell - auf die vertikale Mittelachse bezogen - axial spielfrei drehbar gelagert. Dadurch wird eine äußerst exakte Lagerung geschaffen, die eine hohe Stabilität für die Parallelogrammführungen und die die Plattenteile tragenden Tragarme schafft. Durch diese Ausgestaltung sind somit auch schwere Plattenteile aus Glas oder Stein sicher beweglich.In a further embodiment of the invention, the crossbar on the support frame - related to the vertical central axis - pivoted axially without play. This makes one extremely exact storage created, which is high stability for the Parallelogram guides and those carrying the plate parts Carrier arms creates. This configuration also means Heavy plate parts made of glass or stone can be moved safely.

Doing so with simple Means an axially backlash-free mounting of the crossbar created.

In weiterer Ausgestaltung der Erfindung ist für jeden Plattenteil ein an der Quertraverse angelenkter Tragarm vorgesehen, der mit einem Auflageteller zur Halterung des Plattenteiles versehen ist. Dadurch wird lediglich ein einziger Auflageteller für die Halterung des jeweiligen Plattenteiles benötigt, wodurch sich für den Plattenteil im wesentlichen freie Gestaltungsmöglichkeiten ergeben. Diese Ausgestaltung ist insbesondere für Plattenteile aus Glas vorteilhaft.In a further embodiment of the invention is for each plate part a support arm articulated on the crossbeam is provided, the one with a support plate for holding the plate part is provided. This will only be a single platter needed to hold the respective plate part, which is essentially for the plate part result in free design options. This configuration is particularly advantageous for plate parts made of glass.

In weiterer Ausgestaltung der Erfindung ist beiden Parallelogrammführungen für die jeweilige Ausziehposition jeweils ein Endanschlag zugeordnet. Dadurch werden die Bewegungsmöglichkeiten der Plattenteile auf definierte Bereiche begrenzt, wodurch insbesondere eine exakte Flucht der Plattenteile zueinander sowohl in der Ruhe- als auch in der Ausziehposition erzielt wird.In a further embodiment of the invention, the two parallelogram guides for the respective pull-out position End stop assigned. This increases the range of motion the plate parts limited to defined areas, whereby in particular an exact alignment of the plate parts with each other achieved in both the resting and extended positions becomes.

In weiterer Ausgestaltung der Erfindung mit einem mittels einer Drehlagerung um eine vertikale Drehachse an einem Halter drehbar gelagerten Tragarm für jeden Plattenteil ist die Drehlagerung für den Tragarm als doppelte Axiallagerung ausgebildet.

Ein Ausziehtisch (1), wie er nachfolgend anhand der Fig. 1 bis 13 näher beschrieben ist, weist zwei an einem Traggestell (3, 12) beweglich gelagerte Plattenteile (2) auf, die gemeinsam die Tischfläche des Ausziehtisches (1) in seiner Ruheposition bilden. Beide Plattenteile (2) weisen eine halbkreisförmige Plattenfläche auf, wobei sie derart zueinander ausgerichtet sind, daß sie sich in der Ruheposition zu einer geschlossenen, kreisrunden Tischfläche ergänzen. Beide Plattenteile (2) sind aus Glas hergestellt. Beide Plattenteile (2) sind mittels einer nachfolgend näher beschriebenen Ausziehfunktionseinrichtung (4) auf einem das Traggestell des Ausziehtisches (1) darstellenden Tischsockel (3, 12) gelagert. In ihrer Ruheposition sind die beiden Plattenteile (2) konzentrisch zu einer zentralen, vertikalen Mittelachse (5) ausgerichtet, die gleichzeitig die Mittellängsachse des Tischsockels (3, 12) darstellt. An extendable table (1), as it follows with reference to FIG. 1 to 13 is described, has two on a support frame (3, 12) movably mounted plate parts (2) that together the table surface of the extending table (1) in its rest position form. Both plate parts (2) have a semicircular Plate surface, whereby they are aligned with each other are that in the resting position they form a closed, complete circular table surface. Both plate parts (2) are made of glass. Both plate parts (2) are by means of a pull-out function device described in more detail below (4) on the support frame of the extending table (1) representing table base (3, 12) stored. In their rest position, the two plate parts (2) are concentric aligned to a central, vertical central axis (5), which is also the central longitudinal axis of the table base (3, 12).

Die Plattenteile (2) sind in ihrer Ruheposition außerdem achssymmetrisch zu einer horizontalen Ausziehachse (6) angeordnet, die die Mittelachse (5) schneidet. Die Plattenteile (2) sind mittels der Ausziehfunktionseinrichtung (4) entlang dieser Ausziehachse (6) aus der Ruheposition in ihre Ausziehposition (gestrichelt dargestellt) ausziehbar. In dieser Ausziehposition sind beide Plattenteile (2) um jeweils den gleichen Betrag von der Mittelachse (5) entfernt. Auch in der Ausziehposition sind die Plattenteile (2) koaxial und achssymmetrisch zur Ausziehachse (6) ausgerichtet. In dieser Ausziehposition, in der die Plattenteile (2) zwischen ihren in der Ruheposition aneinander anliegenden Trennkante (2a) einen Abstand belassen, ist in den entstandenen Freiraum ein Einlegeplattenteil (2b) (Fig. 12 und 13) einlegbar, der an die Abmessungen der Plattenteile (2) angepaßt ist. In der Ruheposition der Plattenteile (2) und des Ausziehtisches (1) wird die Einlegeplatte vom Ausziehtisch (1) getrennt gelagert. Selbstverständlich ist es auch möglich, mehrere Einlegeplattenteile zwischen die Plattenteile (2) einzulegen, sobald diese sich in ihrer Ausziehposition befinden.The plate parts (2) are also in their rest position arranged axially symmetrical to a horizontal extension axis (6), which intersects the central axis (5). The plate parts (2) are along by means of the pull-out function device (4) this pull-out axis (6) from the rest position to its pull-out position (shown in dashed lines) extendable. In this extended position are both plate parts (2) by the same Amount removed from the central axis (5). Also in the Pull-out position, the plate parts (2) are coaxial and symmetrical aligned with the pull-out axis (6). In this extended position, in which the plate parts (2) between their in the rest position against one another separating edge (2a) Leaving a distance is an insert plate part in the free space (2b) (Fig. 12 and 13) insertable to the Dimensions of the plate parts (2) is adapted. In the rest position the plate parts (2) and the extending table (1) the insert plate is stored separately from the extension table (1). Of course, it is also possible to have several insert parts insert between the plate parts (2) as soon as they are in their extended position.

Um die beiden Plattenteile (2) aus ihrer Ruheposition in die zueinander beabstandete Ausziehposition auszuziehen oder aus dieser Ausziehposition wieder in die Ruheposition zurückzuschieben, ist jeder Plattenteil (2) mittels jeweils einer nachfolgend näher beschriebenen Parallelogrammführung an dem Tischsockel (3) gelagert. Die stationären Lagerpunkte (L1 und L2) jeder Parallelogrammführung sind auf der Ausziehachse (6) positioniert, so daß sich die beiden Parallelogrammlenker jeder Parallelogrammführung jeweils um diese stationären Lagerpunkte (L1 und L2) drehen. Die beiden Parallelogrammführungen ragen von der Ausziehachse (6) zu gegenüberliegenden Seiten ab, um sich bei ihrer Ausziehbewegung nicht zu behindern. Die beiden Parallelogrammführungen für die beiden Plattenteile (2) sind außerdem in besonders einfacher Weise miteinander synchrongekoppelt, indem die stationären Lagerpunkte (L1) für die zugehörigen Parallelogrammlenker beider Parallelogrammführungen zu einem gemeinsamen Lagerpunkt (L1) zusammengelegt, und exakt auf Höhe der Mittelachse (5) angeordnet sind. Die beiden Parallelogrammlenker, die im stationären Lagerpunkt (L1) gelagert sind, ragen - miteinander fluchtend - zu gegenüberliegenden Seiten punktsymetrisch von der Mittelachse (5) ab. Als Synchronkopplung sind diese beiden Parallelogrammlenker in einfacher Weise einstückig miteinander verbunden, indem sie eine die Mittelachse (5) schneidende Quertraverse (7) bilden, die koaxial zur Mittelachse (5) in dem stationären Lagerpunkt (L1) gelagert ist. Die beiden anderen stationären Lagerpunkte (L2) für die jeweils anderen Parallelogrammlenker der beiden Parallelogrammführungen sind auf der Ausziehachse (6) um gleiche Beträge zu gegenüberliegenden Seiten von der Mittelachse (5) beabstandet. Die in den Lagerpunkten (L2) gelagerten Parallelogrammlenker stellen Koppelstangen (10) dar, wobei die beiden Koppelstangen (10) im Bereich der Lagerpunkte (L2) an einem Auslegerarm (11) gelagert sind, der längs der Ausziehachse (6) verläuft und mit Hilfe von zwei Schraubverbindungen (13) (Fig. 2) auf dem Tischsokkel (3) festgelegt ist.In order to pull the two plate parts (2) out of their rest position into the pull-out position spaced apart from one another or to push them back into the rest position from this pull-out position, each plate part (2) is mounted on the table base (3) by means of a parallelogram guide described in more detail below. The stationary bearing points (L 1 and L 2 ) of each parallelogram guide are positioned on the pull-out axis (6) so that the two parallelogram links of each parallelogram guide each rotate around these stationary bearing points (L 1 and L 2 ). The two parallelogram guides protrude from the pull-out axis (6) on opposite sides so as not to interfere with their pull-out movement. The two parallelogram guides for the two plate parts (2) are also synchronously coupled to one another in a particularly simple manner in that the stationary bearing points (L 1 ) for the associated parallelogram links of both parallelogram guides are combined to form a common bearing point (L 1 ), and exactly at the height of the central axis ( 5) are arranged. The two parallelogram links, which are mounted in the stationary bearing point (L 1 ), project - aligned with each other - point-symmetrically on opposite sides from the central axis (5). As a synchronous coupling, these two parallelogram links are connected to one another in a simple manner by forming a crossbar (7) which intersects the central axis (5) and is mounted coaxially to the central axis (5) in the stationary bearing point (L 1 ). The two other stationary bearing points (L 2 ) for the respective other parallelogram links of the two parallelogram guides are spaced on the extension axis (6) by equal amounts on opposite sides from the central axis (5). The parallelogram links mounted in the bearing points (L2) represent coupling rods (10), the two coupling rods (10) being mounted in the region of the bearing points (L 2 ) on an extension arm (11) which runs along the extension axis (6) and with With the help of two screw connections (13) (Fig. 2) on the table base (3) is fixed.

Um sowohl in der Ruheposition als auch in der Ausziehposition eine exakte Flucht - auf die Ausziehachse (6) bezogen - der Plattenteile (2) zu erzielen und so eine versetzte Positionierung der Plattenteile zueinander zu vermeiden, sind die Winkelbeträge der Parallelogrammlenker relativ zu der Ausziehachse (6) sowohl in der Ruhe- als auch in der Ausziehposition und damit in beiden Endpositionen jeweils identisch.To both in the rest position and in the extended position an exact escape - based on the pull-out axis (6) - the To achieve plate parts (2) and thus an offset positioning of the plate parts to avoid each other are the Angular amounts of the parallelogram links relative to the extension axis (6) in both the rest and extended positions and therefore identical in both end positions.

An den freien Enden der Parallelogrammlenker in Form der Koppelstangen (10) und der Quertraverse (7) beider Parallelogrammführungen ist an jeweils einem in der Ausziehebene verlagerbaren Lagerpunkt (L3 und L4) jeweils ein Tragarm (8) gelagert, der jeweils achsparallel zu der Ausziehachse (6) ausgerichtet ist. Jeder Tragarm (8) weist einen Fortsatz auf, an dessen freiem Ende ein Auflageteller (9) vorgesehen ist, auf dem der zugehörige Plattenteil (2) befestigt ist. Beim dargestellten Ausführungsbeispiel sind die beiden Plattenteile (2) jeweils flächig mit dem Auflageteller (9) verklebt. Jeder Tragarm (8) und der zugehörige Auflageteller (9) untergreifen den zugehörigen Plattenteil (2) exzentrisch, wobei die Klebverbindung jedoch so stabil ausgelegt ist, daß auch die exzentrische Stützung des Plattenteiles (2) durch den zugehörigen Tragarm (8) eine sichere Halterung des jeweiligen Plattenteiles (2) auf dem Tragarm (8) gewährleistet.At the free ends of the parallelogram links in the form of the coupling rods (10) and the cross-beam (7) of both parallelogram guides, a support arm (8) is mounted on a respective bearing point (L 3 and L 4 ) that can be displaced in the pull-out plane, each parallel to the axis Pull-out axis (6) is aligned. Each support arm (8) has an extension, at the free end of which a support plate (9) is provided, on which the associated plate part (2) is attached. In the exemplary embodiment shown, the two plate parts (2) are each adhesively bonded to the support plate (9). Each support arm (8) and the associated support plate (9) reach under the associated plate part (2) eccentrically, but the adhesive connection is designed so stable that the eccentric support of the plate part (2) by the associated support arm (8) provides a secure mounting of the respective plate part (2) on the support arm (8) guaranteed.

Die Quertraverse (7) und die beiden Tragarme (8) sind jeweils als stabile Metallträger ausgebildet, wobei die Tragarme (8) im Bereich der Lagerpunkte (L3) in nachfolgend näher beschriebener, äußerst robuster Weise an der Quertraverse (7) gelagert und die Quertraverse (7) wiederum in äußerst robuster Weise im Lagerpunkt (L1) am Tischsockel (3) gelagert sind. Da die Trag- und Stützfunktion für die Plattenteile (2) nahezu vollständig von den Tragarmen (8) und der Quertraverse (7) übernommen wird, sind die Koppelstangen (10) und der Auslegerarm (11) entsprechend schwächer ausgeführt. Die Koppelstangen (10) und der Auslegerarm (11) sind ebenfalls aus Metall hergestellt, weisen jedoch eine wesentlich geringere Breite und Dicke als die Quertraverse (7) und die Tragarme (8) auf. Die Koppelstangen (10) dienen lediglich zur Parallelverlagerung der beiden Tragarme (8), weisen jedoch nahezu keine Trag- und Stützfunktion für die Tragarme (8) auf. An jedem Tragarm (8) ist jeweils ein Anschlag (12) in Form einer Gummischeibe vorgesehen, die in der Bewegungsbahn des freien Fortsatzes der jeweiligen Koppelstangen (10) am Tragarm (8) befestigt ist und so die Parallelverlagerung des jeweiligen Tragarmes (8) begrenzt, indem die Koppelstange (10) in der Ausziehposition an diesem Anschlag (12) zur Anlage gelangt. Der Anschlag (12) ist so am jeweiligen Tragarm (8) positioniert, daß der Betrag des Winkels der Quertraverse (7) und der Koppelstangen (10) relativ zur Ausziehachse (6) in der Ruheposition identisch mit dem Winkelbetrag von Quertraverse (7) und Koppelstangen (10) in der Ausziehposition ist. Für die Ruheposition ist kein separater Anschlag vorgesehen, da in dieser Ruheposition ohnehin die Trennkanten der beiden Plattenteile (2) bündig aneinander anliegen und somit einen direkten Anschlag bilden. Da die beiden Parallelogrammführungen für die beiden Plattenteile (2) synchron miteinander gekoppelt sind, würde auch ein einziger Anschlag (12) bereits ausreichen, um die Ausziehposition der Plattenteile (2) zu definieren. Die Befestigung der als Anschlag (12) dienenden Gummischeibe an dem Tragarm (8) erfolgt mittels einer Schraubverbindung, wie dies in Fig. 6 dargestellt ist.The crossbeam (7) and the two support arms (8) are each designed as stable metal supports, the support arms (8) being mounted on the crossbeam (7) in the region of the bearing points (L 3 ) in an extremely robust manner, which is described in more detail below Crossbar (7) are in turn mounted in an extremely robust manner in the bearing point (L 1 ) on the table base (3). Since the support and support function for the plate parts (2) is almost completely taken over by the support arms (8) and the crossbeam (7), the coupling rods (10) and the extension arm (11) are correspondingly weaker. The coupling rods (10) and the cantilever arm (11) are also made of metal, but have a significantly smaller width and thickness than the crossbar (7) and the support arms (8). The coupling rods (10) serve only for the parallel displacement of the two support arms (8), but have almost no support and support function for the support arms (8). A stop (12) in the form of a rubber washer is provided on each support arm (8), which is attached to the support arm (8) in the movement path of the free extension of the respective coupling rods (10) and thus limits the parallel displacement of the respective support arm (8) by the coupling rod (10) coming into contact with this stop (12) in the extended position. The stop (12) is positioned on the respective support arm (8) such that the amount of the angle of the crossbar (7) and the coupling rods (10) relative to the extension axis (6) in the rest position is identical to the angle of the crossbar (7) and Coupling rods (10) is in the extended position. No separate stop is provided for the rest position, since in this rest position the separating edges of the two plate parts (2) lie flush against one another and thus form a direct stop. Since the two parallelogram guides for the two plate parts (2) are coupled to each other synchronously, a single stop (12) would already be sufficient to define the extended position of the plate parts (2). The rubber washer serving as a stop (12) is fastened to the support arm (8) by means of a screw connection, as shown in FIG. 6.

Die Quertraverse (7) ist im Lagerpunkt (L1) mittels eines Axialwälzlagers (15a) auf dem Tischsockel (3, 12) gelagert, wobei das Axialwälzlager (15a) konzentrisch zur vertikalen Mittelachse (5) ausgerichtet ist. Das Axialwälzlager (15a) liegt auf einer Sockelplatte (3) des Tischsockels (3, 12) auf, die den oberen Abschluß des Tischsockels (3) bildet und auf dem oberen Rand des eigentlichen Sockelbereichs (12) aufliegt. Der Sockelbereich (12) ist als Hohlzylinder ausgebildet und besteht aus Metall. Unterhalb der Sockelplatte (3) ist in den Sockelzylinder (12) eine Deckplatte (19) eingeschweißt, an der die Sockelplatte (3) mit Hilfe von Schraubverbindungen (14) in Form von Zugschrauben stabil fixiert ist. Um das Spiel des Axialwälzlagers (15a) einstellen zu können und um eine Lagefixierung der Quertraverse (7) relativ zur Mittelachse (5) zu gewährleisten, wird die Quertraverse (7) von einem Schraubbolzen (16) durchdrungen, wobei der als Lagerbolzen dienende Schraubbolzen (16) in einer entsprechenden Durchtrittsbohrung der Quertraverse (7) mittels einer Spielpassung gelagert ist. Der Gewindeschaft des Schraubbolzens (16) greift in eine Gewindebohrung in der Sockelplatte (3) ein. Dem Schraubenkopf des Schraubbolzens (16) ist eine Paßscheibe (15b) zugeordnet, die zwischen der Oberseite der Quertraverse (7) und der Unterseite des Schraubenkopfes (15b) eingelegt ist. Der Schraubbolzen (16) wird in der Sockelplatte (3) so stark angezogen und vorgespannt, daß die Quertraverse (7) axial spielfrei auf das Axialwälzlager (15a) gedrückt wird. Gleichzeitig ist das Anziehen des Schraubbolzens (16) jedoch so maßvoll gewählt, daß keine Selbsthemmung der Lagerung eintritt, und daß im Bereich der Paßscheibe (15b) eine sichere Gleitlagerung zwischen dem Schraubenkopf und der Oberseite der Quertraverse (7) gewährleistet ist. Zur Fixierung der exakten Justierung der Axiallagerung im Bereich des Lagerpunktes (L1) ist dem Schraubbolzen (16) eine Verdrehsicherung in Form einer Fixierspitze (17) zugeordnet, die radial zur Mittelachse (5) in eine entsprechende Gewindebohrung (18) der Sockelplatte (3) einschraubbar ist und sich beim Einschrauben in die Gewindebohrung (18) mit ihrer Spitze in den Gewindeschaft des Schraubbolzens (16) eindrückt. Dadurch wird eine formschlüssige Verdrehsicherung für den Schraubbolzen (16) geschaffen, die in einfacher Weise durch ein entsprechendes Herausschrauben der Fixierspitze (17) wieder gelöst werden kann.The crossbeam (7) is mounted in the bearing point (L 1 ) by means of an axial roller bearing (15a) on the table base (3, 12), the axial roller bearing (15a) being aligned concentrically with the vertical central axis (5). The axial roller bearing (15a) lies on a base plate (3) of the table base (3, 12), which forms the upper end of the table base (3) and rests on the upper edge of the actual base area (12). The base area (12) is designed as a hollow cylinder and is made of metal. Below the base plate (3), a cover plate (19) is welded into the base cylinder (12), on which the base plate (3) is stably fixed by means of screw connections (14) in the form of lag screws. In order to be able to adjust the play of the axial roller bearing (15a) and to ensure that the crossbeam (7) is fixed in position relative to the central axis (5), the crossbeam (7) is penetrated by a screw bolt (16), the screw bolt (serving as bearing bolt) 16) is mounted in a corresponding through-hole of the crossbar (7) by means of a clearance fit. The threaded shaft of the bolt (16) engages in a threaded hole in the base plate (3). The screw head of the screw bolt (16) is assigned a shim (15b) which is inserted between the top of the crossbar (7) and the bottom of the screw head (15b). The screw bolt (16) is tightened and pretensioned in the base plate (3) so strongly that the crossbar (7) is pressed onto the axial roller bearing (15a) without play. At the same time, however, the tightening of the screw bolt (16) is chosen so moderately that there is no self-locking of the bearing, and that a secure sliding bearing between the screw head and the upper side of the crossbar (7) is ensured in the area of the shim (15b). To fix the exact adjustment of the axial bearing in the area of the bearing point (L 1 ), the screw bolt (16) is assigned an anti-rotation device in the form of a fixing tip (17), which radially to the central axis (5) in a corresponding threaded hole (18) of the base plate (3 ) can be screwed in and when screwing into the threaded bore (18), its tip presses into the threaded shaft of the screw bolt (16). This creates a positive locking device for the screw bolt (16), which can be released again in a simple manner by correspondingly unscrewing the fixing tip (17).

Der Auslegerarm (11) ist unmittelbar oberhalb des Schraubenkopfes des Schraubbolzens (16) schräg über die Quertraverse (7) geführt und mit Hilfe von zwei Schraubverbindungen (13) mit der Sockelplatte (3) verschraubt. Jede Schraubverbindung (13) weist jeweils einen in Form eines Abstandshalters ausgebildeten Schraubbolzen auf, der den Auslegerarm (11) in so großem Abstand zur Sockelplatte (3) abstützt, daß der Auslegerarm (11) mit der Quertraverse (7) nicht in Berühung steht. Der Auslegerarm (11) ist mit einer zur Mittelachse (5) koaxialen Durchtrittsbohrung versehen, die beim dargestellten Ausführungsbeispiel ohne Funktion ist. Bei einem nicht dargestellten Ausführungsbeispiel dient diese Bohrung zur Aufnahme eines Fortsatzes des Schraubenkopfes des Schraubbolzens (16), wodurch eine weiter verbesserte koaxiale Ausrichtung des Schraubbolzens (16) und der Quertraverse (7) relativ zur Mittelachse (5) erfolgt. Der Fortsatz des Schraubenkopfes ist bei diesem Ausführungsbeispiel mittels einer Spielpassung in der Bohrung des Auslegerarmes (11) gehalten, um auch bei bereits montiertem Auslegerarm (11) noch eine Justierung der Axiallagerung des Lagerpunktes (L1) zu ermöglichen. The cantilever arm (11) is guided diagonally above the crossbar (7) directly above the screw head of the screw bolt (16) and screwed to the base plate (3) with the aid of two screw connections (13). Each screw connection (13) has a screw bolt in the form of a spacer, which supports the cantilever arm (11) at such a great distance from the base plate (3) that the cantilever arm (11) is not in contact with the crossbar (7). The cantilever arm (11) is provided with a through-bore which is coaxial with the central axis (5) and has no function in the exemplary embodiment shown. In one embodiment, not shown, this hole serves to receive an extension of the screw head of the screw bolt (16), which results in a further improved coaxial alignment of the screw bolt (16) and the crossbar (7) relative to the central axis (5). The extension of the screw head is held in this embodiment by means of a clearance fit in the bore of the cantilever arm (11) in order to allow adjustment of the axial bearing of the bearing point (L 1 ) even with the cantilever arm (11) already installed.

Um Kippmomente im Bereich der Lagerpunkte (L3) des Tragarmes (8) relativ zu der Quertraverse (7) aufzufangen, ohne die Leichtgängigkeit der Lagerung zu beeinflussen, ist jeder Tragarm (8) an der Quertraverse (7) mittels einer doppelten Axiallagerung (21, 22) (Fig. 5 und 8) gelagert. Die doppelte Axiallagerung weist eine untere Axiallagereinheit (21) und eine obere Axiallagereinheit (22) auf, die die Quertraverse (7) an ihrer Oberseite und an ihrer Unterseite flankieren. Durch diese doppelte Axiallagerung wird eine äußerst stabile Lagerung des Tragarmes (8) an der Quertraverse (7) geschaffen, wobei die untere Axiallagereinheit (21) Kippmomente in der einen und die obere Axiallagereinheit (22) Kippmomente in der entgegengesetzten Richtung auffängt. Die Lagefixierung der Axiallagereinheiten (21, 22) erfolgt durch einen stopfenartigen Lagerbock (20), der mittels einer Zugschraube (25), die in eine entsprechende Gewindebohrung des Tragarmes (8) eingreift, mit dem Tragarm (8) verbunden ist. Das Vorsehen einer platzsparenden und ästhetisch ansprechenden Quertraverse zur Lagerung der Tragarme ist nicht auf den Einsatz bei einem Ausziehtisch gemäß dem beschriebenen Ausführungsbeispiel beschränkt. Diese Ausführung ist in gleicher Weise für andere Möbelstücke und insbesondere auch für einen Schwenktisch einsetzbar, wie er aus der DE 41 35 912 C2 bekannt ist. Gleiches gilt für die doppelte Axiallagerung der Tragarme an der Quertraverse.In order to absorb tilting moments in the area of the bearing points (L 3 ) of the support arm (8) relative to the crossmember (7) without affecting the smooth running of the bearing, each support arm (8) on the crossmember (7) must be mounted on a double axial bearing (21 , 22) (FIGS. 5 and 8). The double axial bearing has a lower axial bearing unit (21) and an upper axial bearing unit (22) which flank the crossbar (7) on its top and on its underside. This double axial bearing creates an extremely stable mounting of the support arm (8) on the crossmember (7), the lower axial bearing unit (21) absorbing tilting moments in one direction and the upper axial bearing unit (22) absorbing tilting moments in the opposite direction. The axial bearing units (21, 22) are fixed in position by means of a stopper-like bearing block (20) which is connected to the support arm (8) by means of a tension screw (25) which engages in a corresponding threaded hole in the support arm (8). The provision of a space-saving and aesthetically pleasing crossbar for mounting the support arms is not limited to use with an extension table according to the described embodiment. This version can be used in the same way for other pieces of furniture and in particular also for a swivel table, as is known from DE 41 35 912 C2. The same applies to the double axial bearing of the support arms on the crossbar.
