Nevertheless, other furniture, the standing elements and a connectable furniture panel aufelsen covered by the invention.
Zur Verbindung der Möbelplatte mit den Stehelementen ist vorgesehen, dass zumindest eines der Stehelemente wenlgstens einen Befestigungsflansch aufweist, wobei in der Möbelplatte zumindest eine entsprechende Ausnehmung zur Aufnahme des Befestigungsflansches vorgesehen ist.For connecting the furniture panel with the uprights, it is provided that at least one of the uprights has at least one mounting flange, wherein in the furniture plate at least one corresponding recess for receiving the mounting flange is provided.
Indem nun in der zumindest eine Ausnehmungen Klemmbereiche vorgesehen sind, mittels denen die Möbelplatte durch Drehen der Möbelplatte relativ zu den Stehelementen mit den Stehelementen verriegelbar ist, ist zum einen ein einfacher Zusammenbau des Möbels gewährleistet, da eine derartige Drehung eine besonders einfache Bewegungsform darstellt. Zum anderen entsteht durch die Anordnung der Klemmbereiche in der Ausnehmung eine auf einen Kraftschluss basierende Verbindung, wenn die Möbelplatte relativ zu den Stehelementen entsprechend gedreht wird, sodass die Möbelplatte mit den Stehelementen verriegelt ist. Dabei kann die Ausnehmung derart ausgebildet sein, dass zusätzlich eine formschlüssige Verbindung gegeben ist. Im Vergleich zum Stand der Technik ist durch die Klemmbereiche eine Weiterdrehung, wodurch ein unerwünschtes Abheben der Möbelplatte von den Stehelementen leicht möglich wäre, nicht mehr möglich. Dadurch weist die Verbindung der Möbelplatte mit den Stehelementen eine hohe Stabilität, d.h. einen hohen mechanischen Zusammenhalt auf. Die kraftschlüssige Verbindung entsteht dabei durch eine Normalkraft zwischen Teilen des Befestigungsflansches und der Klemmbereiche, wobei eine Weiterdrehung durch Reibungskräfte verhindert wird, sodass erfindungsgemäße eine Verriegelung gegeben ist.By now in the at least one recesses clamping areas are provided by means of which the furniture panel is locked by turning the furniture plate relative to the standing elements with the uprights, on the one hand a simple assembly of the furniture is guaranteed, since such rotation represents a particularly simple form of movement. On the other hand arises by the arrangement of the clamping areas in the recess a based on a traction connection when the furniture panel is rotated relative to the standing elements accordingly, so that the furniture panel is locked with the uprights. In this case, the recess may be formed such that in addition a positive connection is given. Compared to the prior art is by the clamping areas a further rotation, whereby an unwanted lifting the furniture panel would be easily possible from the standing elements, no longer possible. As a result, the connection of the furniture panel with the standing elements has a high stability, i. a high mechanical cohesion. The frictional connection is formed by a normal force between parts of the mounting flange and the clamping areas, wherein a further rotation is prevented by friction forces, so that according to the invention a lock is given.
Durch eine Drehung in die entgegengesetzte Richtung kann die kraftschlüssige Verbindung in Folge der Klemmung mittels der Klemmbereiche wieder gelöst werden, sodass die Zerlegung des zusammengesetzten Möbels genauso einfach wie das Zusammensetzen vonstatten gehen kann.By a rotation in the opposite direction, the frictional connection can be solved by means of the clamping areas again as a result of the clamping, so that the decomposition of the assembled furniture can go just as easily as the assembly vonstatten.
Weitere vorteilhafte Ausführungen der Erfindung sind in den abhängigen Ansprüchen definiert.Further advantageous embodiments of the invention are defined in the dependent claims.
In einer besonders bevorzugten Ausführungsform der Erfindung ist die zumindest eine Ausnehmung für den wenigstens einen Befestigungsflansch im Innenbereich einer Seite der Möbelplatte angeordnet. In diesem Fall kann vorgesehen sein, dass die Ausnehmung nur einen gewissen endlichen Teilbereich im Inneren der Möbelplatte umfasst, sodass durch die Wandung der Ausnehmung in der Möbelplatte Anschlagflächen gegeben sind, mittels denen die Drehung der Möbelplatte relativ zu den Stehelementen auf einen gewissen Windelbereich beschränkt wird. Durch die Anordnung von Haltestegen in gewissen Teilbereichen der Ausnehmung kann nach einer gewissen Drehung der Sitzmöbelplatte eine formschlüssige Verbindung, die ein Abheben der Möbelplatte von den Stehelementen verhindert, realisiert werden. Die Klemmbereiche sorgen in diesem Fall zusätzlich dazu für eine kraftschlüssige Verbindung, die eine Verriegelung der Möbelplatte mit den Stehelementen ermöglicht. Die Ausnehmung im Innenbereich der Möbelplatte schafft zusätzlich dazu die Möglichkeit, dass die Außenseite des Möbels formschön und durchgehend ausgebildet ist, da diese Ausnehmung beispielsweise im Innenbereich an der Unterseite des Möbels anordenbar ist.In a particularly preferred embodiment of the invention, the at least one recess for the at least one fastening flange is arranged in the inner region of one side of the furniture panel. In this case, it can be provided that the recess comprises only a certain finite portion in the interior of the furniture panel, so that by the wall of the recess in the furniture panel stop surfaces are given, by means of which the rotation of the furniture panel relative to the standing elements is limited to a certain diaper area. The arrangement of retaining webs in certain areas of the recess can be realized after a certain rotation of the seating plate a positive connection, which prevents lifting of the furniture panel of the uprights. In this case, the clamping areas additionally provide for a non-positive connection which makes it possible to lock the furniture panel to the standing elements. The recess in the interior of the furniture panel also creates the possibility that the outside of the furniture is shapely and continuous, since this recess can be arranged, for example, in the interior of the bottom of the cabinet.
Besonders bevorzugt ist eine als Sacköffnung ausgebildete Ausnehmung. Im Gegensatz zu einer Durchtrittsöffnung ermöglicht eine derartige Sacköffnung eine gleichmäßige und durchgehende Fläche der Möbelplatte, wobei diese Fläche jener Fläche, in der die Ausnehmung angeordnet ist, gegenüberliegend ist. Falls das erfindungsgemäße Möbel ein Sitzmöbel ist, ist die Ausnehmung an der der Sitzfläche entgegengesetzten Fläche angeordnet. Die als Sacköffnung ausgebildete Ausnehmung ermöglicht damit eine durchgängige und bündige Sitzfläche.Particularly preferred is a recess formed as a blind opening. In contrast to a passage opening, such a blind opening allows a uniform and continuous surface of the furniture panel, this surface of that surface in which the recess is arranged, is opposite. If the furniture according to the invention is a chair, the recess is arranged on the opposite surface of the seat. The trained as a bag opening recess thus allows a continuous and flush seat.
Aber auch für den Fall einer als Durchtrittsöffnung ausgebildeten Ausnehmung kann eine bündige Sitzfläche ermöglicht werden, indem der Befestigungsflansch über eine entsprechende Form und Größe verfügt, sodass er die Durchtrittsöffnung an jener Seite, die von den Stehelementen in zusammengesetztem Zustand des Möbels abgewandt ist, möglichst vollständig ausfüllt.But even in the case of a recess formed as a passage opening a flush seat can be made possible by the mounting flange has a corresponding shape and size, so that it is as complete as possible the passage opening on that side, which faces away from the standing elements in the assembled state of the furniture fills.
In einer Ausführungsform der Erfindung sind die Klemmbereiche als ausgefräste Haltestege ausgebildet, wobei die Haltestege zusätzlich die Aufgaben des Formschlusses ermöglichen können. Sind beispielsweise die Haltestege relativ zu den zwei Flächen der Möbelplatte schräg verlaufend angeordnet, wird bei einer Drehung der Möbelplatte relativ zu den Stehelementen in eine gewisse Drehrichtung die Klemmkraft proportional zum Drehwinkel erhöht. Die Klemmbereiche ermöglichen in diesem Fall eine Verbindung, wie sie bei einer keilförmigen Verbindung auftreten. Die Haltestege können dabei der schiefen Ebene des Keils und der Befestigungsflansch jenem Teil, der an der schiefen Ebene des Keils anliegt, entsprechen.In one embodiment of the invention, the clamping areas are formed as milled retaining webs, wherein the retaining webs can additionally allow the tasks of positive engagement. For example, if the holding webs arranged obliquely relative to the two surfaces of the furniture panel, the clamping force is increased in proportion to the rotation angle relative to the standing elements in a certain direction of rotation with a rotation of the furniture panel. The clamping areas in this case allow a connection, as they occur in a wedge-shaped connection. The holding webs may correspond to the inclined plane of the wedge and the mounting flange that part, which rests against the inclined plane of the wedge.
In einer weiteren Ausführungsform der Erfindung weist zumindest eines der Stehelemente wenigstens einen Zentrierzapfen auf, der in ein in der Möbelplatte angeordnetes Zentrierloch einführbar ist. Im zusammengesetzten Zustand ergeben dieser Zentrierzapfen und das entsprechende Zentrierloch eine Zapfen-Loch-Verbindung. Für eine symmetrische, beispielsweise kreisrunde, Möbelplatte, kann das Zentrierloch im Mittelpunkt der Möbelplatte angeordnet sein. Generell löst ein derartiger Zentrierzapfen in Verbindung mit einem derartigen Zentrierloch die Aufgabe, dass ein Aufsetzen der Möbelplatte auf die zusammengesteckten Stehelemente möglichst einfach erfolgen kann. Sobald der Zentrierzapfen in das Zentrierloch eingeführt ist, kann mit der Drehung der Möbelplatte relativ zu den Stehelementen der Verriegelungsvorgang begonnen werden.In a further embodiment of the invention, at least one of the standing elements has at least one centering pin, which can be inserted into a centering hole arranged in the furniture panel. In the assembled state, this centering pin and the corresponding centering hole result in a pin-hole connection. For a symmetrical, for example circular, furniture panel, the centering hole can be arranged in the center of the furniture panel. In general, such a centering pin in conjunction with such a centering hole solves the problem that placing the furniture panel on the assembled standing elements can be done as easily as possible. Once the centering pin is inserted into the centering hole, the rotation of the furniture panel relative to the standing members of the locking operation can be started.
Statt in der Möbelplatte kann In einer weiteren Ausführungsform der Erfindung vorgesehen sein, dass das Zentrierloch In einem der Stehelemente angeordnet ist. In diesem Fall weist die Möbelplatte den entsprechenden Zentrierzapfen auf. Sinn und Zweck der obigen zwei Zapfen-Loch-Verbindungen entsprechen sich.Instead of the furniture panel may be provided in a further embodiment of the invention that the centering hole is arranged in one of the standing elements. In this case, the furniture plate on the corresponding centering pin. The purpose of the above two pin-hole connections are the same.
Zur weiteren Erhöhung des Zusammenhalts der Verbindung Kann die Verriegelungskraft erhöht werden, wenn, wie in einer weiteren Ausführungsform der Erfindung vorgesehen, die Stehelemente wenigstens zwei Befestigungsflansche aufweisen. Entsprechend sind dann in der Möbelplatte zwei Ausnehmungen zur Aufnahme der Befestigungsflansche vorgesehen. Vorzugsweise ist dabei vorgesehen, dass diese Befestigungsflansche auf einem einzigen der Stehelemente angeordnet sind.To further increase the integrity of the connection, the locking force can be increased if, as provided in a further embodiment of the invention, the standing elements have at least two mounting flanges. Accordingly, two recesses for receiving the mounting flanges are then provided in the furniture panel. Preferably, it is provided that these mounting flanges are arranged on a single of the standing elements.
Besonders bevorzugt ist vorgesehen, dass zumindest eines der Stehelemente wenigstens eine Nut aufweist, durch die die Stehelemente vorzugsweise in einem Winkel von im Wesentlichen 90° zusammensteckbar sind. Bevorzugt weist jedes der Stehelemente wenigstens eine derartige Nut auf, wobei durch die Nut oder die Nuten die Stehelemente besonders einfach zusammensteckbar sind, indem ein entsprechender Bereich eines der Stehelemente in eine Nut, die im anderen Stehelement angeordnet ist, eingeschoben wird. Durch einen Winkel von im Wesentlichen 90° ergibt sich eine kreuzförmige Auflagefläche der Stehelemente, welche der Stabilität des zusammengesetzten Möbels zugute kommt. Die Nuten können dabei beispielsweise einen im Wesentlichen zylindrischen Querschnitt aufweisen. Durch ein derartiges Zusammenstecken der Stehelemente wird eine Feder-Nut-Verbindung zwischen den Stehelementen gebildet, wobei der in die Nut eingeschobene Bereich des entsprechenden Stehelements die Funktion der Feder übernimmt.It is particularly preferably provided that at least one of the uprights has at least one groove, through which the uprights are preferably plugged together at an angle of substantially 90 °. Preferably, each of the uprights has at least one such groove, wherein the standing elements are particularly easily plugged together by the groove or grooves by a corresponding region of the standing elements in a groove which is arranged in the other standing element, is inserted. By an angle of substantially 90 ° results in a cross-shaped bearing surface of the standing elements, which benefits the stability of the assembled furniture. The grooves can, for example, a substantially cylindrical cross-section exhibit. Such a mating of the standing elements a spring-groove connection between the uprights is formed, wherein the inserted into the groove portion of the corresponding standing element takes over the function of the spring.
Bevorzugt ist vorgesehen, dass die Stehelemente jeweils einstückig ausgebildet sind. In diesem Fall können die Befestigungsflansche ausgefräst sein. Es wäre aber auch möglich, die Befestigungsflansche beispielsweise durch eine Verklebung oder andere Befestigungsmethoden auf die Stehelemente anzuordnen.It is preferably provided that the standing elements are each formed in one piece. In this case, the mounting flanges can be milled out. But it would also be possible to arrange the mounting flanges, for example by gluing or other fastening methods on the standing elements.
Bevorzugt ist vorgesehen, dass die Stehelemente und zusätzlich oder alternativ die Möbelplatte im Wesentlichen aus Holz bestehen, da derartige Holzmöbel eine gemeinhin als angenehm empfundene Wohnatmosphäre schaffen. Dazu sind auch im Möbelbau verwendete Holzwerkstoffplatten, Spanfaserplatten oder andere Holz umfassende Verbundplatten zu zählen. Dennoch ist es auch möglich, dass die Stehelemente und/oder die Möbelplatte Kunststoff oder Metall umfassen oder aus diesen Werkstoffen bestehen. Metallhaltige Bauteile sind besonders stabil, während kunststoffhaltige Bauteile leicht und daher besonders für einen Transport gut geeignet und zudem wetterfest sind.Preferably, it is provided that the standing elements and additionally or alternatively the furniture panel essentially consist of wood, since such wood furniture create a commonly perceived as comfortable living atmosphere. For this purpose, wood panels used in furniture construction, chipboard or other wood comprehensive composite panels are to be counted. Nevertheless, it is also possible that the standing elements and / or the furniture panel comprise plastic or metal or consist of these materials. Metal-containing components are particularly stable, while plastic-containing components are lightweight and therefore particularly well suited for transport and also weatherproof.
In einer weiteren Ausführungsform der Erfindung kann es vorgesehen sein, dass zur Verstauung des Möbels die zusammensteckbaren Stehelemente im zerlegten Zustand des Möbels aufeinander bzw. übereinander gestapelt werden. Zu diesem Zweck kann es vorgesehen sein, dass die zwei Stehelemente im Wesentlichen ähnliche Ausmaße aufweisen. Indem nun vorgesehen ist, dass in zumindest einem der Stehelemente wenigstens eine weitere Ausnehmung angeordnet ist, wobei durch die wenigstens eine weitere Ausnehmung eine Aufnahme für die Möbelplatte in den gestapelten Stehelementen ausgebildet ist, kann die Möbelplatte in zerlegtem Zustand des Möbels in dieser Aufnahme angeordnet werden. Es wird daher durch die aufeinander bzw. übereinander gestapelten Stehelemente ein Stauraum für die Möbelplatte ausgebildet, wobei die Möbelplatte innerhalb bzw. zwischen den Stehelementen des zerlegten Möbels verstaut werden kann. Dadurch ist einerseits ein gemeinsames Verstauen der Einzelteile des Möbels möglich und es ergibt sich zudem ein überaus geringer Stauraumbedarf. Auf gesonderte Befestigungsvorrichtungen zur Fixierung der Möbelplatte in der von der weiteren Ausnehmung oder von den weiteren Ausnehmungen gebildeten Aufnahme kann verzichtet werden. Dabei kann die wenigstens eine weitere Ausnehmung und die daraus gebildete Aufnahme derart ausgebildet sein, dass eine formschlüssige Verbindung zwischen der Möbelplatte und den übereinander bzw. aufeinander gestapelten Stehelementen gegeben ist.In a further embodiment of the invention, it can be provided that the plugged-together standing elements in the disassembled state of the furniture are stacked on top of each other or stacked to stow the furniture. For this purpose it can be provided that the two standing elements have substantially similar dimensions. By now provided that at least one further recess is arranged in at least one of the standing elements, wherein a receptacle for the furniture panel is formed in the stacked standing elements by the at least one further recess, the furniture panel can be arranged in disassembled state of the furniture in this recording , It is therefore formed by the stacked or stacked standing elements a storage space for the furniture panel, wherein the furniture panel can be stowed within or between the standing elements of the disassembled furniture. As a result, on the one hand a common stowage of the items of the furniture is possible and it also results in an extremely low storage space requirement. On separate fastening devices for fixing the furniture plate in the of the further recess or of the other Recesses formed recording can be dispensed with. In this case, the at least one further recess and the receptacle formed therefrom may be designed such that a form-fitting connection is provided between the furniture panel and the standing elements stacked one above the other or one another.
In einer besonders bevorzugten Ausführungsform der Erfindung sind in der wenigstens einen weiteren Ausnehmung Haltemittel für die Möbelplatte angeordnet. Zusätzlich oder alternativ kann die wenigstens eine weitere Ausnehmung selbst als Halteelement ausgebildet sein. Zu derartigen Haltemitteln zählen beispielsweise Haltestege, die in der wenigstens einen Ausnehmung z.B. durch Ausfräsen angeordnet sind. Diese Haltemittel können einerseits zur Ausbildung einer formschlüssigen Verbindung der Möbelplatte in der durch die wenigstens eine weitere Ausnehmung gebildeten Aufnahme dienen. Zu diesem Zweck können die Haltemittel als nutförmige Einkerbung ausgebildet sein, die mit korrespondierenden Stegelementen der Möbelplatte in formschlüssigen Eingriff bringbar ist, wodurch eine Feder-Nut-Verbindung ausgebildet wird. Die Anordnungen der Einkerbung und der Stegelemente kann für diese Zwecke auch vertauscht werden.In a particularly preferred embodiment of the invention holding means for the furniture panel are arranged in the at least one further recess. Additionally or alternatively, the at least one further recess itself may be formed as a holding element. Such holding means include, for example, holding webs, which in the at least one recess, e.g. are arranged by milling. On the one hand, these retaining means can serve to form a positive connection of the furniture panel in the receptacle formed by the at least one further recess. For this purpose, the holding means may be formed as a groove-shaped notch, which can be brought into positive engagement with corresponding web elements of the furniture panel, whereby a spring-groove connection is formed. The arrangements of the notch and the web elements can also be reversed for these purposes.
Andererseits kann durch diese Haltemittel oder durch die Ausbildung der weiteren Ausnehmung als Halteelemente auch eine kraftschlüssige Verbindung realisiert werden. Durch eine derartige kraftschlüssige Verbindung, die auf Reibung basiert, ist eine noch stabilere Halterung der Möbelplatte in den übereinander bzw. aufeinander gestapelten Stehelementen möglich, sodass das Möbel in zerlegtem Zustand auch besonders gut transportiert werden kann. Zu diesem Zweck kann es vorgesehen sein, dass eine Verkeilung der Haltemittel bzw. des Haltelements mit der Möbelplatte vorgesehen ist, beispielsweise durch eine kraftschlüssige Ausbildung des obigen formschlüssigen Eingriffs.On the other hand, can be realized by these holding means or by the formation of the further recess as holding elements and a positive connection. By such a frictional connection, which is based on friction, an even more stable mounting of the furniture plate in the stacked or stacked standing elements is possible, so that the furniture can also be transported very well in disassembled state. For this purpose it can be provided that a wedging of the holding means or the holding element is provided with the furniture plate, for example by a non-positive formation of the above positive engagement.
Die weitere Ausnehmung(en) in den Stehelementen sind dabei dergestalt, dass die Möbelplatte in dieser oder in diesen weiteren Ausnehmung(en) aufgenommen werden kann. Ist der dadurch geschaffene Raum geringfügig kleiner als die Möbelplatte, kann die Mäbelplatte in die weitere Ausnehmung(en) der Stehelemente eingeklemmt und somit von dieser oder von diesen mittels einer Klemmkraft gehalten werden. Dadurch ergibt sich die Möglichkeit einer sicheren Verstauung des Möbels in zerlegtem Zustand, was wiederum für den Transport des Möbels besonders gewünscht sein kann.The further recess (s) in the standing elements are such that the furniture panel can be received in this or in this further recess (s). If the space created thereby is slightly smaller than the furniture panel, the blade plate can be clamped in the further recess (s) of the standing elements and thus held by this or these by means of a clamping force. This results in the possibility of a secure stowage of the furniture in disassembled Condition, which in turn may be particularly desirable for the transport of the furniture.
In einer weiteren Ausführungsform der Erfindung wird eine erhöhte Stabilität der Verbindung der zwei Stehelemente ermöglicht, indem zumindest eines der Stehelemente wenigstens ein Nut aufweist, in die das andere Stehelement unter Ausbildung einer Feder-Nut-Verbindung bereichsweise einschiebbar ist, wodurch die verbindbaren Stehelemente zusammensteckbar sind. Üblicherweise bilden derartige Feder-Nut-Verbindungen eine formschlüssige Verbindung, wobei jener Bereich des anderen Stehelements, der in die Nut einschiebbar ist und somit als Feder ausgebildet ist bzw. der Feder einer Feder-Nut-Verbindung entspricht, der Ausmaße der Nut entsprechende Ausmaße aufweisen muss. Weist jener Bereich, der in die Nut eingeschoben wird, eine zu hohe Materialstärke auf, ist ein Einschieben, also ein Verbinden der verbindbaren Stehelemente gar nicht mehr möglich. Ist andererseits der einzuschiebende Bereich zu schwach, weist die Verbindung der zwei Stehelemente ein Spiel auf, wodurch eine stabile Verbindung nicht realisierbar ist. Aus diesem Grund sind bei herkömmlichen, formschlüssigen Feder-Nut-Verbindungen hohe Anforderungen an die Fertigungstoleranzen zu stellen.In a further embodiment of the invention, an increased stability of the connection of the two uprights is made possible by at least one of the uprights has at least one groove into which the other upright element is partially inserted to form a tongue and groove connection, whereby the connectable standing elements are plugged together , Usually, such tongue and groove connections form a positive connection, wherein that portion of the other standing element, which is inserted into the groove and thus formed as a spring or the spring corresponds to a tongue and groove connection, the dimensions of the groove have corresponding dimensions got to. If that area which is pushed into the groove has too high a material thickness, it is no longer possible to insert it, ie to connect the connectable standing elements. On the other hand, if the area to be inserted is too weak, the connection of the two standing elements on a game, whereby a stable connection is not feasible. For this reason, high demands are placed on the manufacturing tolerances in conventional, positive tongue-and-groove connections.
Das Stehelement, in dem die Nut angeordnet ist weist eine gewisse Elastizität auf, sodass die Nut unter entsprechender Krafteinwirkung geringfügig aufweitbar ist. Dieser Möglichkeit der Aufweitung sind aber enge Grenzen gesetzt. Ist nun vorgesehen, dass im Bereich der Nut mehrere zusätzliche Ausnehmungen vorgesehen sind, die die Steifigkeit des Stehelements herabsetzen, kann diese Möglichkeit der Aufweitung der Nut erhöht werden. Das eine Stehelement ist also im Bereich der Nut etwas nachgiebiger, d.h. etwas elastischer, sodass der Bereich des anderen Stehelements, der in die Nut eingeschoben wird, eine Materialstärke aufweisen kann, die etwas größer als die Nut selbst ist. Aufgrund der zusätzlichen Ausnehmungen ist nämlich die Steifigkeit des einen Stehelements derart herabgesetzt, dass die Nut auseinandergedrückt werden kann, wodurch gleichzeitig neben der formschlüssigen Verbindung eine kraftschlüssige Verbindung realisiert wird. Der eingeschobene Bereich verspreizt die Nut und es entsteht eine keilförmige Verbindung mit einer Klemmwirkung. Durch eine derartige formschlüssige und kraftschlüssige Verbindung ist eine äußerst stabile Verbindung herstellbar. Die zusätzlichen Ausnehmungen bedeuten in diesem Zusammenhang, dass diese zusätzlich zur Nut vorgesehen sind. Durch die zusätzlichen Ausnehmungen wird gleichzeitig die Aufgabe gelöst, ein erfindungsgemäßes Möbel zur Verfügung zu stellen, bei dem geringere Anforderungen an die Herstellungstoleranzen für die Verbindung der verbindbaren Stehelemente gestellt werden.The standing element in which the groove is arranged has a certain elasticity, so that the groove is slightly expandable under corresponding force. However, this possibility of expansion is limited. If it is now provided that a plurality of additional recesses are provided in the region of the groove, which reduce the rigidity of the standing element, this possibility of widening the groove can be increased. The one standing element is thus slightly more flexible in the region of the groove, ie somewhat more elastic, so that the region of the other standing element which is inserted into the groove can have a material thickness which is slightly larger than the groove itself. Because of the additional recesses namely the stiffness of a standing element is so reduced that the groove can be pressed apart, whereby at the same time in addition to the positive connection, a positive connection is realized. The inserted area expands the groove and creates a wedge-shaped connection with a clamping action. By such a positive and non-positive connection an extremely stable connection can be produced. The additional recesses in this context mean that they are provided in addition to the groove. By the additional recesses, the object is at the same time to provide an inventive furniture available to be made in the lower demands on the manufacturing tolerances for the connection of the connectable standing elements.
Dabei kann durch den zusätzlich zum Formschluss der Feder-Nut-Verbindung realisierten Kraftschluss infolge der Klemmwirkung eine Lagefixierung der zwel Stehelemente erreicht werden.It can be achieved by the addition to the positive connection of the spring-groove connection realized adhesion as a result of the clamping action a positional fixation of the two standing elements.

Dieser Lagefixierung kommt zugute, dass die Stützbeine 10, 20 zumindest teilweise elastisch ausgebildet sind. Beim Anordnen der Möbelplatte 4 in den Ausnehmungen 17, 17', 18, 18' werden aufgrund der Größenverhältnisse die Stützbeine 10 bzw. 20 etwas auseinandergedrückt. Die Stabilität dieser Verbindung ist natürlich nur so groß gewählt, dass die Möbelplatte 4, nachdem sie werkzeuglos in die durch die Ausnehmungen 17, 17', 18, 18' gebildete Aufnahme einsetzbar ist, auch wieder werkzeuglos aus dieser Aufnahme entnehmbar ist. Die als Querschnittsabschwächungen ausgebildeten Ausnehmungen 17, 17', 18, 18' können dabei in Richtung der Außenseite des jeweiligen Stehelementes 2, 3 eine zunehmende Querschnittsdicke aufweisen, damit eine keilförmige Verbindung der Möbelplatte 4 mit den Ausnehmungen 17, 17', 18, 18' leichter realisierbar ist.This fixation is beneficial that the
Die Querschnittsabschwächung der Ausnehmungen 17, 17', 18, 18' ist dabei derart ausgebildet, dass die Stapelhöhe der aufeinander bzw. übereinander gestapelten Stehelemente 2 und 3 durch die aufgenommene Möbelplatte 4 nicht oder nur unwesentlich geändert wird. Mit anderen Worten: Die Stapelhöhe der aufeinander gestapelten Stehelemente 2, 3 ist unabhängig davon, ob in der durch die Ausnehmungen 17, 17', 18, 18' gebildete Aufnahme die Möbelplatte 4 aufgenommen ist oder nicht.The cross-sectional weakening of the
Das erste Stehelement 2 weist eine Nut 12 auf, in die ein entsprechender Bereich 13 des zweiten Stehelements 3 einschiebbar ist. Durch dieses bereichweise Einschieben werden die zwei Stehelemente 2, 3 zusammengesteckt, wobei die Stehelemente 2, 3 einen Winkel von etwa 90° ausbilden, wodurch eine möglichst hohe Standfestigkeit des zusammengesetzten Möbels 1, das in dieser Ausführungsform ein Sitzmöbel darstellt, gegeben ist. Durch das Einschieben des Bereichs 13 des zweiten Stehelements 3 in die Nut 12 entsteht eine Feder-Nut-Verbindung, die eine formschlüssige Verbindung zwischen den zwei Stehelementen 2 und 3 ermöglicht, falls die Breite der Nut 12 zumindest eine der Stärke des Materials im Bereich 13 des Stehelements 3 entsprechend ist. Ist jedoch die Materialstärke im Bereich 13 zu groß, kann dieser Bereich nicht in die Nut 12 eingeschoben werden. Aus diesem Grund sind seitlich entlang der Längsseiten der Nut 12 schräg und beabstandet zu diesen Längsseiten zusätzliche Ausnehmungen 19, 21, 19', 21' angeordnet. Weitere zusätzliche Ausnehmungen 22, 22' sind in Form von Einbuchtungen an der ansonsten im Wesentlichen einen zylindrischen Querschnitt aufweisenden Nut 12 angeordnet. Diese symmetrisch bezüglich der Längsachse des Stehelements 2 angeordneten zusätzlichen Ausnehmungen 19, 21, 22 sowie 19', 21', 22' dienen dazu, die Steifigkeit des Materials des Stehelements 2, das ebenso wie das Stehelement 3 und die Möbelplatte 4 aus Holz besteht, herabzusetzen. Durch diese herabgesetzte Steifigkeit ist die Nut 12 ähnlich wie die Stützbeine 10 und 20 bei der Aufnahme der Möbelplatte 4 etwas elastisch bzw. federnd, sodass der Bereich 13 auch dann in die Nut 12 eingeschoben werden kann, wenn dessen Materialstärke geringfügig breiter als die Nut 12 ist. Die Ausmaße der Nut 12 sowie des darin einzuschiebenden Bereichs 13 sind dabei derart gewählt, dass ein werkzeugloses Zusammenstecken und Zerlegen der Stehelemente 2 und 3 möglich ist.The
Dadurch, dass infolge des eingeschobenen Bereiches 13 die Nut 12 etwas auseinandergedrückt und verspreizt wird, entsteht eine Klemmkraft wie bei einer keilförmigen Verbindung, wobei der Keil durch den eingeschobenen Bereich 13 ausgebildet ist. Zusätzlich zur formschlüssigen Verbindung einer herkömmlichen Feder-Nut-Verbindung ist damit eine kraftschlüssige Verbindung gegeben, sodass eine äußerst stabile Verbindung der zusammengesteckten Stehelementen 2 und 3 realisierbar ist, wobei auf externe Befestigungsmittel, wie beispielsweise Schrauben od. dgl. verzichtet werden kann, sodass ein werkzeugloses Zerlegen und Zusammenbauen möglich ist, ohne Stabilitätseinbußen des zusammengesetzten Möbels 1 hinnehmen zu müssen. Die Nut 12 weist eine Symmetrieachse, die der Symmetrieachse des Stehelements 2 entspricht. Die zusätzlichen Ausnehmungen 19, 21, 22, 19', 21', 22' sind symmetrisch zu dieser Symmetrieachse angeordnet.Due to the fact that, as a result of the inserted
An jener Seite des zweiten Stehelements 3, an der die weitere Nut 14 angeordnet ist, sind auch zwei Befestigungsflansche 5 und 5' angeordnet. Die Befestigungsflansche 5 und 5' weisen jeweils an der Außenseite des Stehelements 3 Vorsprünge sowie Bereiche 16 bzw. 16' auf, die in die als Haltestege ausgebildeten Klemmbereiche 8 und 8' für die Verriegelung der Möbelplatte 4 eingreifen. Statt nur eines einzigen Vorsprungs pro Befestigungsflansch 5 und 5' wäre es auch denkbar, jeweils zwei Vorsprünge anzuordnen. In diesem Fall müssten die Ausnehmungen 6 und 6' weitere Klemmbereiche aufweisen, die den bereits vorhandenen Klemmbereichen 8 und 8' gegenüber liegend angeordnet sein müssten.On that side of the second standing
