Description

Die Erfindung betrifft einen Stuhl oder ein ähnliches Sitzmöbel mit wenigstens drei Beinen und einem zwischen diesen im Bereich der Sitzebene angeordneten Halte­rahmen, an dem die Beine befestigt sind und der als Auflager für eine Sitzfläche dient.The invention relates to a chair or similar seating furniture with at least three legs and a holding frame arranged between them in the region of the seat plane, to which the legs are attached and which serves as a support for a seat.

Ein Stuhl mit einem zwischen den Stuhlbeinen aufgenom­menen und letztere miteinander verbindenden Halterahmen, der zugleich als Auflager für eine Sitzfläche dient,­ist bereits bekannt (druckschriftlich nicht belegbar). Der Halterahmen dieses vorbekannten Stuhls besteht aus in Eckpunkten miteinander verleimten Rahmenteilen, die sich jeweils zwischen benachbarten Stuhlbeinen erstrecken. Die aneinanderstoßenden und miteinander verleimten Enden der Rahmenteile sind gegenüber deren Längserstreckungen unter etwa 45° abgebogen und als in entsprechende Querausnehmungen der Stuhlbeine eingeleimte Zapfen ausgebildet.A chair with a holding frame which is received between the chair legs and connects the latter to one another and which also serves as a support for a seat surface is already known (cannot be documented in printed form). The holding frame of this previously known chair consists of frame parts glued together at corner points, each of which extends between adjacent chair legs. The abutting and glued ends of the frame parts are bent relative to their longitudinal extensions at about 45 ° and formed as pins glued into corresponding transverse recesses in the chair legs.

Obgleich angesichts der bei derartigen Stühlen erfor­derlichen Stabilität der Halterahmen aus Massivhölzern oder mehrfach verleimten Schichthölzern, besteht, die beträchtliche Materialstärke aufweisen, ist der Halte­rahmen bei dem vorbekannten Stuhl nicht hinreichend ver­windungssteif. Naturgemäß hat ein Stuhl mit einem derartigen Rahmen erhebliches Gewicht. Letzteres wirkt insbesondere bei der Ausbildung als Stapelstuhl störend.Although in view of the stability required for such chairs, the holding frame consists of solid wood or multi-glued laminated wood, which have considerable material thickness, the holding frame in the previously known chair is not sufficiently rigid. Naturally, a chair with such a frame has considerable weight. The latter is particularly disruptive when training as a stacking chair.

Demgegenüber besteht die der Erfindung zugrundeliegende Aufgabe in der Schaffung eines Stuhls oder eines ähn­lichen Sitzmöbels großer Verwindungssteifigkeit und Tragfähigkeit, dessen Gewicht gegenüber dem bekannten Stuhl merklich reduziert sein soll.In contrast, the object on which the invention is based is to create a chair or a similar piece of seating furniture with great torsional rigidity and load-bearing capacity, the weight of which should be markedly reduced compared to the known chair.

Gelöst ist diese Aufgabe dadurch, daß bei dem Sitz­möbel nach dem Oberbegriff des Patentanspruchs 1 der die Beine miteinander verbindende Halterahmen als Kasten­rahmen ausgebildet ist und je eine obere und untere Deckplatte aufweist, die mit seitlichen Rahmenteilen schubfest verbunden sind.This object is achieved in that in the seating furniture according to the preamble of claim 1, the holding frame connecting the legs to one another is designed as a box frame and each has an upper and lower cover plate, which are connected with lateral frame parts in a shear-resistant manner.

Bei der Erfindung handelt es sich somit darum, daß an die Stelle des aus verleimten Rahmenteilen beträcht­licher Materialstärke bestehenden Halterahmens bei dem vorbekannten Stuhl ein Kastenprofil getreten ist, bei dem im Vergleich zu den Rahmenteilen des vorbekannten Halterahmens die Zargen und Deckplatten nur geringe Materialdicke zu haben brauchen. Unbeschadet nur geringer Materialstärken hat der bei dem erfindungsgemäßen Sitz­möbel als Hohlprofil ausgebildete Kastenträger große Trag­fähigkeit und ist vor allem äußerst verwindungssteif sowie leichtgewichtig.In the invention, it is therefore a case that a box profile has taken the place of the holding frame consisting of glued frame parts of considerable material thickness in the known chair, in which, in comparison with the frame parts of the known holding frame, the frames and cover plates need only have a small material thickness . Without prejudice to only small material thicknesses, the box girder, which is designed as a hollow profile in the seating furniture according to the invention, has a high load-bearing capacity and is above all extremely torsion-resistant and lightweight.

Gemäß einer zweckmäßigen Ausgestaltung bestehen bei dem erfindungsgemäßen Sitzmöbel die seitlichen Rahmen­teile und/oder die Deckplatten des Halterahmens aus mehrfach verleimten Schichthölzern, die angesichts der Ausbildung des Halterahmens als ober- und unter­seitig geschlossenes Kastenprofil nur geringe Material­stärken zu haben brauchen. Insbesondere kann es sich bei den Schichthölzern um Sperrholz handeln.According to an expedient embodiment, the lateral frame parts and / or the cover plates of the holding frame consist of multiply glued laminated timber in the seating furniture according to the invention, which need to have only small material thicknesses given the design of the holding frame as a box profile closed on the top and bottom. In particular, the plywood can be plywood.

Eine andere zweckmäßige Ausgestaltung sieht vor, daß der Halterahmen als ein der Anzahl der Beine entspre­chendes Vieleck mit sich jeweils zwischen benachbarten Beinen erstreckenden und im Bereich der Eckpunkte, an denen die Beine befestigt sind, fest miteinander verbundenen Zargen ausgebildet ist.Another expedient embodiment provides that the holding frame is designed as a polygon corresponding to the number of legs, each with frames extending between adjacent legs and firmly connected to one another in the region of the corner points to which the legs are attached.

Gemäß einer Weiterbildung der vorgenannten Ausgestaltung können die Zargen zumindest annähernd die Form von Kreisbogenstücken haben, die sich zwischen jeweils benachbarten Beinen bogenförmig zum Inneren der Sitzfläche hin erstrecken, wobei die miteinander verbundenen Enden aneinandergrenzender Zargen unter Ausbildung sternför­miger Eckpunkte aneinander anliegen und mithin flächen­haft miteinander verbunden sind.According to a further development of the aforementioned embodiment, the frames can have at least approximately the shape of circular arc pieces that extend in an arc-shaped manner between the respective adjacent legs towards the interior of the seat surface, the ends of adjoining frames which are connected to one another abutting one another to form star-shaped corner points and are therefore areally connected to one another .

Bei dieser Weiterbildung kann auch zwischen den miteinan­der verbundenen Enden benachbarter Zargen jeweils eine verstärkende Sperrholzeinlage angeordnet und mit den Zargenenden verbunden, insbesondere verleimt sein.In this development, a reinforcing plywood insert can also be arranged between the interconnected ends of adjacent frames and connected, in particular glued, to the frame ends.

Gemäß einer anderen Ausgestaltung sind die Beine des Sitzmöbels mittels innenseitig an diesen angebrachter Beschläge mit dem Halterahmen verbunden. Dabei hat sich als zweckmäßig erwiesen, wenn die Beschläge als U-Profile mit einem am jeweiligen Bein anliegenden Steg und je einem die obere und untere Deckplatte des Kastenrahmens im Bereich der sternförmigen Ecken übergreifenden Schenkel ausgebildet sind. Dadurch ist eine verwindungssteife Verbindung zwischen der jeweiligen Ecke des Kastenträgers und dem zugeordneten Beschlag und über letzteren mit dem jeweiligen Bein des Sitzmöbels gewährleistet.According to another embodiment, the legs of the seating furniture are connected to the holding frame by means of fittings attached to them on the inside. It did proven to be expedient if the fittings are designed as U-profiles with a web resting against the respective leg and one leg each overlapping the upper and lower cover plate of the box frame in the region of the star-shaped corners. This ensures a torsionally rigid connection between the respective corner of the box girder and the associated fitting and, via the latter, with the respective leg of the seating furniture.

Gemäß einer Weiterbildung dieser Ausgestaltung kann der Steg eines jeden Beschlags auf der zu den Schenkeln hinweisenden Seite auch als von seitlichen Stegteilen begrenzte Tasche gestaltet sein, in der der Endabschnitt der jeweils angeschlossenen Ecke des Kastenrahmens auf­genommen ist.According to a development of this embodiment, the web of each fitting on the side facing the legs can also be designed as a pocket delimited by lateral web parts, in which the end section of the respectively connected corner of the box frame is received.

Bei dem in den Fig. 1 und 2 veranschaulichten Stuhl 10 handelt es sich um einen Stapelstuhl mit je zwei vorderen und hinteren Stuhlbeinen 11, 12, die mittels eines Kasten­rahmens 14 miteinander verbunden sind. Der Kastenrahmen bildet neben seiner Funktion als verwindungssteifes Verbindungsmittel für die Stuhlbeine gleichzeitig ein Auflager für eine in hier nicht weiter interessierender Weise befestigte Sitzfläche 15. Während die vorderen Stuhlbeine 11 in Sitzhöhe enden, erstrecken sich die hinteren Stuhlbeine 12 nach oben über die Sitzfläche hinaus und nehmen zwischen sich eine Rückenlehne 16 auf.The chair 10 illustrated in FIGS. 1 and 2 is a stacking chair with two front and rear chair legs 11, 12, which are connected to one another by means of a box frame 14. In addition to its function as a torsionally rigid connecting means for the chair legs, the box frame also forms a support for a seat surface 15 which is not of interest here. While the front chair legs 11 end at seat height, the rear chair legs 12 extend upwards beyond the seat surface and take between them a backrest 16.

Der Kastenrahmen 14 besteht aus vier seitlichen Zargen 17 und je einer oberen und unteren Deckplatte 18, 19. Bei den Zargen handelt es sich um Kreisbogenstücke aus mehr­fach verleimtem Schichtholz, die in vier sternförmigen Ecken 20 auslaufen und sich im übrigen zwischen diesen Ecken bogenförmig zurückspringend, also beim fertigen Stuhl unter der Sitzfläche erstrecken. Die Enden 21 je­weils benachbarter Zargen 17 sind im Bereich der Ecken 20 des Kastenrahmens 14 in parallel zueinander verlaufenden Abschnitten zusammengeführt und unter Zwischenlage je­weils einer verstärkenden Sperrholzeinlage 22 miteinan­der verleimt. Mit den oberen und unteren Stirnkanten der einen sternförmigen Rahmen bildenden Zargen 17 sind die beiden Deckplatten 18, 19 schubfest verleimt. Die Deck­platten reichen bis in die dem Anschluß der Stuhlbeine 11, 12 an den Kastenrahmen dienenden Ecken 20.The box frame 14 consists of four side frames 17 and an upper and lower cover plate 18, 19. The frames are circular arc pieces made of multiply glued laminated wood, which end in four star-shaped corners 20 and, in the rest, spring back in an arc between these corners, so extend under the seat of the finished chair. The ends 21 of adjacent frames 17 are brought together in the region of the corners 20 of the box frame 14 in sections running parallel to one another and glued to one another with the interposition of a reinforcing plywood insert 22 in each case. With the upper and lower front edges of the frames 17 forming a star-shaped frame, the two cover plates 18, 19 are glued in a shear-resistant manner. The cover plates extend into the corners 20 serving to connect the chair legs 11, 12 to the box frame.

Es handelt sich bei dem Kastenrahmen 14 um ein leicht­gewichtiges Hohlprofil großer Verwindungssteifigkeit, dessen Zargen 17 und Deckplatten 18, 19 nur geringe Materialstärken haben und beispielsweise aus Sperrholz bestehen können.The box frame 14 is a light-weight hollow profile with high torsional rigidity, the frames 17 and cover plates 18, 19 of which have only small material thicknesses and can consist, for example, of plywood.

Im Bereich jeder der durch Einleimen von Sperrholzein­lagen 22 zwischen den Enden benachbarter Zargen 17 verstärkten Ecken 20 des Kastenträgers 14 ist an letzteren mittels je eines Beschlages 24 ein Stuhlbein 11 bzw. 12 verwindungssteif angeschlossen.In the area of each of the corners 20 of the box girder 14, which are reinforced by gluing plywood inserts 22 between the ends of adjacent frames 17, a chair leg 11 or 12 is connected to the latter by means of a fitting 24.

Bei den Beschlägen handelt es sich um als U-Profile ausgebildete Druckgußteile mit einem am jeweiligen Stuhlbein anliegenden Steg 25 und zwei sich im Abstand voneinander vom Steg nach der vom Stuhlbein entfernten Seite forterstreckenden oberen und unteren Schenkeln 26, 27, die im Bereich der jeweiligen Ecke 20 des Kasten­rahmens 14 diesen ober- und unterseitig umgreifen. Dabei liegt der obere Schenkel 26 auf der oberen Deckplatte 18 des Kastenträgers 14 auf, während der untere Schenkel 27 im Interesse der Stapelbarkeit des Stuhls 10 in die untere Deckplatte 19 eingelassen und daher mit dieser unterseitig flächenbündig ist.The fittings are die-cast parts designed as U-profiles with a web 25 resting on the respective chair leg and two upper and lower legs 26, 27 which extend in the area of the respective corner from each other to the side remote from the chair leg 20 of the box frame 14 grip around the top and bottom. The upper leg 26 rests on the upper cover plate 18 of the box girder 14, while the lower leg 27 is inserted into the lower cover plate 19 in the interest of the stackability of the chair 10 and is therefore flush with the underside thereof.

Die an den Stuhlbeinen 11, 12 anliegenden Stege 25 sind der Innenkontur der Stuhlbeine entsprechend konkav ausgebildet und mit zwei im Abstand voneinander angeordneten und in entsprechende Ausnehmungen der Stuhl­beine eingelassenen Zapfen 28 versehen sowie mittels durch letztere hindurch verdeckt eingeschraubter Halteschrauben 29 an den Stuhlbeinen befestigt. Auf der jeweils anderen Seite der Stege 25 erstreckt sich eine von seitlichen Stegteilen 30 eingefaßte nutartige Tasche 31 zwischen den beiden Schenkeln 26, 27 des Beschlags 24. In diese nutartige Tasche greift der an die Form der Tasche angepaßte Endabschnitt der jeweiligen Ecke des Kastenrahmens formschlüssig ein.The webs 25 resting on the chair legs 11, 12 are correspondingly concave to the inner contour of the chair legs and are provided with two pins 28 arranged at a distance from one another and recessed in corresponding recesses in the chair legs, and fastened to the chair legs by means of retaining screws 29 which are concealed and screwed through the latter. On the other side of the webs 25, a groove-like pocket 31 bordered by lateral web parts 30 extends between the two legs 26, 27 of the fitting 24. The end section of the respective corner of the respective corner of the box frame, which is adapted to the shape of the pocket, engages in this groove-like pocket .

Die sich vom Steg eines jeden Beschlags 24 nach der vom jeweiligen Stuhlbein abgewandten Seite forter­streckenden Schenkel 26, 27, die ober- und unterseitig an den beiden Deckplatten 18, 19 des Kastenrahmens an­liegen, sind mit den Deckplatten verklebt sowie zu­sätzlich mittels nur angedeuteter Befestigungsschrau­ben 32, 33 verschraubt. Ferner sind die Endabschnitte der sternförmigen Ecken 20 des Kastenrahmens 14 mit Kleber in die nutartigen Taschen 31 der Beschläge eingepreßt.The legs 26, 27 extending from the web of each fitting 24 to the side facing away from the respective chair leg, which rest on the top and bottom sides of the two cover plates 18, 19 of the box frame, are glued to the cover plates and additionally by means of only indicated fastening screws 32, 33 screwed. Furthermore, the end sections of the star-shaped corners 20 of the box frame 14 are pressed with adhesive into the groove-like pockets 31 of the fittings.

Der als verwindungssteifes Hohlprofil ausgebildete Kastenträger 14 ist mittels der Beschläge 24 im Bereich der von den miteinander verleimten Enden der Zargen 17 gebildeten Ecken 20 somit verwindungssteif mit den Stuhlbeinen verbunden.The box girder 14, which is designed as a torsionally rigid hollow profile, is thus connected to the chair legs in a torsionally rigid manner by means of the fittings 24 in the region of the corners 20 formed by the glued ends of the frames 17.

Bei der veranschaulichten Ausführungsform ist die obere Deckplatte 18 des Kastenrahmens 14 mit vier symmetrisch zu dessen Flächenausdehnung angeordneten Lochungen 35 ausgerüstet, in die unterseitig an der Sitzfläche 15 in entsprechender Lage angeordnete Verrastungsnocken form­schlüssig, aber lösbar eingreifen. Die Verrastungsnocken der abnehmbaren Sitzfläche sind in der Zeichnung nicht dargestellt.In the illustrated embodiment, the upper cover plate 18 of the box frame 14 is equipped with four perforations 35 arranged symmetrically to its surface area, into which latching cams arranged in a corresponding position on the underside of the seat surface 15 engage in a form-fitting but releasable manner. The locking cams of the removable seat are not shown in the drawing.
