Description

Technisches GebietTechnical field

Die Erfindung betrifft einen Mehrzweckstuhl zum Einsatz in Veranstaltungshallen, welcher an seinen Gestellbeinen ein Adaptionselement aufweist, das zur Aufnahme von Zubehör, wie z. B. Armlehne und Verkettungselement, vorgesehen ist.The invention relates to a multi-purpose chair for use in event halls, which has an adaptation element on its frame legs, which is for receiving of accessories such as B. armrest and interlinking element is provided.

Stand der TechnikState of the art

Ein derartiger Mehrzweckstuhl ist beispielsweise unter dem Namen "Space" aus einem Prospekt der Firma Wiesner-Hager Möbel GmbH aus dem Jahre 1992 bekannt. Bei diesem bekannten Stuhl ist das Adaptionselement als Teil des Vorderbeines ausgebildet und infolgedessen als großes Gußteil ausgelegt. Dies stellt nachteilig einen beträchtlichen Fabrikationsaufwand dar.Such a multi-purpose chair is known, for example, under the name "Space" a prospectus from Wiesner-Hager Möbel GmbH from 1992. In this known chair, the adaptation element is part of the front leg trained and consequently designed as a large casting. This poses disadvantageously represents a considerable manufacturing outlay.

Ein weiterer Nachteil dieser bekannten Stühle besteht darin, daß bei einer Verbindung mehrerer derartiger Stühle mittels Verkettungselemente die Stühle nur insoweit voneinander gegen Verdrehung gesichert sind, als die relativ kleine Anlagefläche des Adaptionselementes dies sicherstellt. Daher besteht die Gefahr, daß das Verkettungselement leicht ausbricht. Another disadvantage of these known chairs is that when connected several such chairs by means of interlinking elements, the chairs only to this extent are secured against rotation from each other than the relatively small contact surface of the adaptation element ensures this. There is therefore a risk that the interlinking element breaks out easily.

Wird zwischen zwei verkettete Stühle eine Armlehne montiert, so ist diese bei den Space-Stühlen nicht mittig positioniert, was zu einer Verschlechterung des Sitzkomforts und des äußeren Eindruckes der Bestuhlung führt.If an armrest is installed between two linked chairs, this is the case with the Space chairs are not positioned centrally, which leads to a deterioration in seating comfort and the external impression of the seating.

Schließlich ist es bei den bekannten Stühlen nur möglich, die Reihennummer, nicht aber die Sitzplatznummer, am Adaptionselement zu montieren. Nachteilig kommt hinzu, daß das dazu benutzte Clipteil einerseits nicht diebstahlsicher ist, und andererseits aufgrund der verformten Bleche relativ aufwendig herzustellen ist.After all, with the known chairs it is only possible to enter the row number, but not the seat number to be mounted on the adaptation element. adversely in addition, the clip part used for this is on the one hand not theft-proof, and on the other hand to produce relatively complex due to the deformed sheets is.

Darstellung der ErfindungPresentation of the invention

Die Erfindung versucht, diese Nachteile zu vermeiden. Ihr liegt die Aufgabe zugrunde, einen Mehrzweckstuhl mit einem Adaptionselement zu schaffen, welcher mit geringem Aufwand herzustellen ist, und bei welchem das Adaptionselement geeignet ist, einerseits eine einfache Verkettung sowie Sitzplatz- und Reihennummerierung der Stühle zu ermöglichen und andererseits eine Armlehne oder ein Schreibtablar mittig zwischen zwei verkettete Stühlen aufzunehmen. Außerdem soll ein Verdrehen mehrerer miteinander verketteter Stühle sicher vermieden werden.The invention tries to avoid these disadvantages. It is based on the task to create a multi-purpose chair with an adaptation element, which can be produced with little effort, and in which the adaptation element is suitable, on the one hand, simple chaining as well as seat and row numbering to allow the chairs and on the other hand an armrest or to place a writing tablet in the middle between two linked chairs. Moreover should avoid twisting several chairs linked together become.

Erfindungsgemäß wird dies dadurch erreicht, daß bei einem Mehrzweckstuhl gemäß dem Oberbegriff des Anspruchs 1 das Adaptionselement ein separates Kleinteil ist, welches aus einem Kopf und einem u-profilförmigen Schuh mit einem sich vertikal zum Kopf erstreckenden Schlitz besteht, wobei der Schuh im Profilgestell des Hinterbeines angeordnet und mit Hilfe eines im Schlitz vorgesehenen Gewindestiftes verspannt ist, und wobei der Kopf einerseits zwei symmetrisch zum Schlitz angeordnete Öffnungen zur Aufnahme von Mitteln zum Verschrauben des Kopfes mit dem Vorderbein aufweist und diese Mittel mittels Muttern mit aussenseitigen Inbusschlüsselangriffen mit dem Vorderbein verschraubt sind, und daß andererseits der Kopf ein im Zentrum angeordnetes Gewinde zur wahlweisen Aufnahme eines ersten Kopplungselementes aufweist.According to the invention this is achieved in that according to a multi-purpose chair the preamble of claim 1, the adaptation element a separate Small part is, which consists of a head and a U-shaped shoe with a There is a slot extending vertically to the head, with the shoe in the profile frame the rear leg and with the help of one provided in the slot Grub screw is clamped, and the head on the one hand two symmetrical openings arranged to the slot for receiving means for screwing of the head with the front leg and these means by means of nuts with outside Allen key attacks are screwed to the front leg, and that on the other hand the head has a thread arranged in the center for optional Includes a first coupling element.

Die Vorteile der Erfindung bestehen darin, daß das Adaptionselement auf Grund seiner geringen Größe ökonomisch günstig herzustellen ist, und es sowohl als statisch notwendiges Verbindungselement zwischen Vorder- und Hinterbein fungiert als auch als ein Bauteil, an dem das für Mehrzweckstühle notwendige Zubehör, wie Armlehne, Schreibtablar, Kopplungselemente, Sitzplatznummer und Reihennummer, angebracht werden können.The advantages of the invention are that the adaptation element due to its small size is economically inexpensive to manufacture, and it both as statically necessary connecting element between the front and rear leg acts as well as a component on which the accessories necessary for multi-purpose chairs, such as armrest, writing tablet, coupling elements, seat number and row number, can be attached.

Es ist zweckmäßig, wenn das Mittel zum Verschrauben des Adaptionselementkopfes mit dem Vorderbein ein zweites Kopplungselement oder eine handelsübliche Inbusschraube ist, deren Kopf mit einer Blende abdeckbar ist. Das Kopplungselement wird gewählt, wenn der Mehrzweckstuhl mit anderen Stühlen zu einer Reihe verbunden werden soll, die Inbusschrauben dagegen, wenn keine Verkettung vorgesehen ist oder wenn der Stuhl am Ende einer Reihe steht.It is useful if the means for screwing the adapter element head with the front leg a second coupling element or a commercially available one It is an Allen screw whose head can be covered with a cover. The coupling element is chosen when the multipurpose chair with other chairs too a row should be connected, the Allen screws, if none Linking is provided or when the chair is at the end of a row.

Ferner ist es vorteilhaft, wenn die ersten und zweiten Kopplungselemente derart ausgebildet sind, daß sie ein gegenseitiges Ineinandergreifen ermöglichen. Dadurch ist eine Stuhlverkettung einfach herstellbar.It is also advantageous if the first and second coupling elements are of this type are trained to enable mutual interlocking. Thereby a chair chain is easy to manufacture.

Schließlich ist es zweckmäßig, wenn an der Oberseite des Kopfes des Adaptionselementes eine Vertiefung zur Aufnahme eines Dauermagneten und eines darüber angeordneten Nummerierungs-Blechplättchens vorgesehen ist. Der Magnet hält die Plättchen in der Vertiefung des Adaptionselementes fest, so daß diese relativ diebstahlsicher angebracht sind, was bei Mehrzweckstühlen in Veranstaltungshallen sehr wichtig ist. Außerdem ist ein vorteilhaftes Handling sichergestellt, wenn die Stühle umgestellt und die Nummernplättchen ausgetauscht werden müssen. Finally, it is useful if on the top of the head of the adaptation element a recess to hold a permanent magnet and one above arranged numbering plate is provided. The magnet holds the plate in the recess of the adaptation element, so that this are relatively theft-proof, which is what multipurpose chairs in event halls is very important. In addition, advantageous handling is ensured when the chairs are moved and the number plates are exchanged have to.

Von Vorteil ist weiterhin, wenn am Kopf des Adaptionselementes die Aufnahme einer Armlehne oder eines Schreibtablars vorgesehen ist. In das Adaptionselement müssen in einem solchen Falle lediglich längere Kopplungselemente eingeführt werden.It is also advantageous if the recording at the head of the adaptation element an armrest or a writing tablet is provided. In the adaptation element In such a case, only longer coupling elements have to be introduced become.

Schließlich ist es vorteilhaft, wenn die Gestellbeine des Mehrzweckstuhles seitlich nach außen derart abgewinkelt sind, daß zwei benachbarte, mittels im Adaptionsteil angeordneter Kopplungselemente verbundene Mehrzweckstühle mit ihren Hinterbeinen und ihren Vorderbeinen am Boden aneinanderstoßen. Ein Verdrehen der Stühle gegeneinander ist damit unterbunden.Finally, it is advantageous if the legs of the multi-purpose chair are on the side are angled to the outside in such a way that two neighboring ones by means of the adaptation part arranged coupling elements connected multipurpose chairs with their Bump back legs and forelegs together on the floor. A twisting the chairs against each other is prevented.

Weg zur Ausführung der ErfindungWay of carrying out the invention

Nachfolgend wird die Erfindung eines Ausführungsbeispieles und der Figuren 1 bis 6 näher erläutert.In the following, the invention of an exemplary embodiment and of FIGS. 1 to 6 explained in more detail.

Fig. 1 zeigt eine Gesamtseitenansicht eines erfindungsgemäßen Mehrzweckstuhles. Der Mehrzweckstuhl weist neben der Sitzfläche und der Rückenlehne, deren Ausbildung für die vorliegende Erfindung unwesentlich ist, ein Profilgestell auf, welches aus einem gebogenen Vorderbein 7 und einem geraden Hinterbein 3 besteht. Vorderbein 7 und Hinterbein 3 sind etwa v-förmig zueinander angeordnet, wobei das "v" auf dem Kopf steht. Die Sitzfläche ist in der Nähe der Spitze des "v" angeordnet. Vorderbein 7 und Hinterbein 3 sind über ein Adaptionselemente 1 miteinander verbunden, welches auch, wie mit der gestrichelten Linie angedeutet, zur Aufnahme einer Armlehne 14 dienen kann. Das Adaptionselement ist beispielsweise ein AluminiumAluminium-Druckgußteil, welches kostengünstig hergestellt werden kann und anhand der folgenden Figuren 2 bis 6 näher beschrieben wird. Fig. 1 shows an overall side view of a multi-purpose chair according to the invention. The multi-purpose chair has the seat and backrest, their Training is not essential to the present invention, a profile frame, which consists of a curved front leg 7 and a straight rear leg 3 consists. Front leg 7 and rear leg 3 are arranged approximately in a V-shape with respect to one another, with the "v" upside down. The seat is near the top of the "v" arranged. Front leg 7 and rear leg 3 are via an adaptation element 1 connected, which, as indicated by the dashed line, can serve to accommodate an armrest 14. The adaptation element is, for example an aluminum-aluminum die-cast part, which can be manufactured inexpensively can and is described in more detail with reference to the following Figures 2 to 6.

Entlang der Linien A-A und B-B sind in den Figuren 2 bis 6 verschiedene Ausführungsbeispiele der Erfindung dargestellt, wobei die mit "a" gekennzeichneten Figuren Schnitte entlang der Linie A-A und die mit "b" gekennzeichneten Figuren Schnitte entlang der Linie B-B darstellen.Along the lines A-A and B-B there are different exemplary embodiments in FIGS. 2 to 6 of the invention, the figures marked with "a" Cuts along line A-A and the figures marked with "b" Show cuts along the line B-B.

Fig. 2a und Fig. 2b zeigen ein erstes Ausführungsbeispiel der Erfindung. Das Adaptionselement 1 besteht aus einem Kopf 1a und einem dazu sich senkrecht erstreckenden Schuh 1b. Der Schuh 1b hat die Form eines u-Profiles mit einem Schlitz 2. Die Abmasse des Schuhes 1b sind so auf die Abmasse des Hinterbeines 3 abgestimmt, daß der Schuh 1 b in das Hohlprofil des Hinterbeines 3 gesteckt werden kann und mit einem Gewindestift 4, welcher einen stirnseitigen Inbusschlüsselangriff aufweist, verspannt werden kann. Der Kopf 1a des Adaptiönselementes 1 weist zwei senkrecht und symmetrisch zum Schlitz 2 angeordnete Öffnungen auf, in die ein Kopplungselement 5 gesteckt wird, welches mit Hilfe von Muttern mit aussenseitigen Inbusschlüsselangriffen 6 mit dem Vorderbein 7 verschraubt ist. Das Kopplungselemente 5 besteht aus zwei Gewindebolzen und einen breiteren Kopfteil, wobei die Gewindebolzen des Kopplungselementes 5 länger sind als das Kopfteil 1a des Adaptionsteiles 1 und daher im eingebaute Zustand in das Innere des Vorderbeines 7 ragen. Das Kopfteil des Kopplungselementes 5 reicht im eingebauten Zustand außen an das Kopfteil 1a des Adaptionselementes 1 heran (siehe Fig. 2b). Im Zentrum des Kopfteiles 1a ist eine Gewindebohrung 8 angeordnet. Außerdem ist an der Oberseite des Kopfteiles 1a eine Vertiefung 10 vorgesehen, in die ein Magnet 11 eingelegt werden kann, über den ein Metallplättchen mit der Sitzplatznummer bzw. Reihennummer problemlos anzubringen ist. Der Magnet 11 hält das Nummemplättchen fest, so daß es relativ diebstahlsicher angebracht ist, denn nur ein Magnet mit einer größeren Anziehungskraft als der innenliegende Magnet 11 ermöglicht eine Demontage der Plättchen (siehe Fig. 3). 2a and 2b show a first embodiment of the invention. The Adaptation element 1 consists of a head 1 a and a perpendicular thereto extending shoe 1b. The shoe 1b has the shape of a u-profile with a Slit 2. The dimensions of the shoe 1b are so on the dimensions of the rear leg 3 matched that the shoe 1 b inserted into the hollow profile of the rear leg 3 can be and with a grub screw 4, which attacks an end Allen key exhibits, can be tensioned. The head 1a of the adapter element 1 has two openings arranged perpendicularly and symmetrically to the slot 2 on, into which a coupling element 5 is inserted, which with the help of Nuts with external hex key attacks 6 screwed to the front leg 7 is. The coupling element 5 consists of two threaded bolts and one wider head part, the threaded bolts of the coupling element 5 longer are as the head part 1a of the adaptation part 1 and therefore in the installed state protrude into the inside of the front leg 7. The head part of the coupling element 5 extends in the installed state to the outside of the head part 1a of the adaptation element 1 approach (see Fig. 2b). In the center of the head part 1a is a threaded hole 8 arranged. In addition, at the top of the head part 1a Indentation 10 is provided, into which a magnet 11 can be inserted, via which easily attach a metal plate with the seat number or row number is. The magnet 11 holds the number plate so that it is relative Theft-proof is attached, because only a magnet with a greater attraction as the internal magnet 11 allows disassembly of the plates (see Fig. 3).

Fig. 3a und Fig. 3b zeigen, daß in die Gewindebohrung 8 eine weiteres Kopplungselement 9 mit seinem Schaft eingeschraubt werden kann. Die Köpfe der beiden Kopplungselemente 5 und 9 berühren sich teilweise. Mit Hilfe der Kopplungselemente 5 und 9 ist eine Stuhlverkettung realisierbar, wie in Fig. 6 im Detail gezeigt wird.Fig. 3a and Fig. 3b show that in the threaded bore 8, a further coupling element 9 can be screwed with its shaft. The heads of the two Coupling elements 5 and 9 partially touch. With the help of the coupling elements 5 and 9 a chair linkage can be realized, as shown in FIG. 6 in detail becomes.

In Fig. 4a und Fig. 4b ist ein anderes Ausführungsbeispiel der Erfindung dargestellt. Es unterscheidet sich von den bisher beschriebenen Beispielen dadurch, daß im Adaptionselement 1 keine Kopplungselemente 5, 9 vorgesehen sind. Das Kopfteil 1a wird mit dem Vorderbeinprofil 7 mit handelsüblichen Inbusschrauben 12 verbunden. Wie bereits oben beschrieben, werden die Inbusschrauben 12 mit Muttern 6 mit außenseitigen Inbusschlüsselangriffen im Inneren des Vorderbeines 7 verschraubt. Die Schraubenköpfe werden mit Hilfe einer Blende 13 abgedeckt, die mittels eines angespritzten Schnappelementes am Kopfteil 1a des Adaptionselementes (siehe Fig. 4a) leicht montierbar ist.4a and 4b show another embodiment of the invention. It differs from the examples described so far in that that no coupling elements 5, 9 are provided in the adaptation element 1. The The head section 1a is attached to the front leg profile 7 using standard Allen screws 12 connected. As already described above, the Allen screws 12 are with Nuts 6 with external Allen wrench attacks on the inside of the front leg 7 screwed. The screw heads are covered with an aperture 13, by means of a molded snap element on the head part 1a of the adaptation element (see Fig. 4a) is easy to assemble.

Fig. 5a und Fig. 5b unterscheiden sich von den bisherigen Ausführungsbeispielen dadurch, daß das Adaptionselement 1 zusätzlich eine Armlehne 14 aufnimmt.5a and 5b differ from the previous exemplary embodiments in that the adaptation element 1 also receives an armrest 14.

Selbstverständlich kann anstelle der Armlehne 14 auch ein Schreibtablar vorgesehen sein. Je nachdem, ob eine Stuhlverkettung gewünscht ist, kann die Armlehne 14 wahlweise mit Kopplungselementen 5, 9 oder einer Blende 13 kombiniert werden. Der Schaft (Gewindebolzen) der Kopplungselemente 5, 9 muß gegenüber dem in Fig. 2 und Fig. 3 gezeigten Beispiel lediglich etwas länger sein, damit dieses zusätzliche Zubehör genügend Platz hat.Of course, a writing tablet can also be provided instead of the armrest 14 his. Depending on whether a chair chain is desired, the armrest 14 optionally combined with coupling elements 5, 9 or an aperture 13 become. The shaft (threaded bolt) of the coupling elements 5, 9 must be opposite the example shown in FIGS. 2 and 3 may only be a little longer, so this additional accessory has enough space.

In Fig. 6 ist schließlich in einem Schnitt die Verkettung von zwei nebeneinanderstehenden Mehrzweckstühlen dargestellt. Jeder der Stühle weist das oben bereits beschriebene Adaptionselement 1 auf, mit dem einerseits jeweils das Vorderbein 7 mit dem Hinterbein 3 verbunden ist. Andererseits ist in einem der beiden Adaptionselemente 1 ein Kopplungselement 9 angeordnet, welches über die in beiden Adaptionselementen 1 angeordneten Kopplungselemente 5 eine einfache Stuhlverkettung ermöglicht. Sind die Gestellbeine 3, 7 seitlich nach außen derart abgewinkelt, daß die mittels der Kopplungselemente 5, 9 verbundenen Mehrzweckstühle jeweils mit ihren Vorderbeinen 7 und Hinterbeine 3 am Boden aneinanderstoßen, dann ist zusätzlich eine Verdrehung der Stühle untereinander unterbunden.Finally, in Fig. 6, the concatenation of two adjacent to one another is in a section Multi-purpose chairs shown. Each of the chairs already shows that above described adaptation element 1, on the one hand with the front leg 7 is connected to the rear leg 3. On the other hand is in one of the two adaptation elements 1, a coupling element 9 is arranged, which in both Adaptation elements 1 arranged coupling elements 5 a simple chair chain allows. If the frame legs 3, 7 are angled laterally outwards, that the multipurpose chairs connected by means of the coupling elements 5, 9 butt each with their front legs 7 and rear legs 3 on the ground, then twisting of the chairs among themselves is prevented.
