Description

Es ist bekannt, Sitzplatten ,aus: Sperrholz im Biegeverfahren herzustellen und ferner Sitzplatten aus wärmebildsamen Preßstofferi zu pressen. Nahe liegt es, im letzteren Fall Holzspäne als Füllmittel zu verwenden. Es: muß dann dafür Sorge getragen werden, daß kein Abrieb stattfindet und daß die Oberfläche ,des Stuhles glatt ist bzw. mit Überzugswerkstoffen, wie Textilgeweben, Gummi od. dgl., versehen: wird.It is known to manufacture seat panels from: plywood using a bending process and furthermore to press seat plates from thermosensitive pressed material. It is obvious in the latter case, use wood chips as a filler. It: must then take care of it be worn so that there is no wear and tear and that the surface of the chair is smooth or provided with coating materials such as textile fabrics, rubber or the like: will.

Demgegenüber wird nach der Erfindung :die Sitzplatte aus einem Furnier, z. B. aus Holz, aus einem Polymethacrylsäureester oder einer anderen wärme= bildsamen Masse, bzw. einer Sperrholzplatte und. einer aus Holzspänen und einem Bindemittel bestehenden Preßstoffeinlage 'hergestellt. Es ergibt sich somit ein verhältnismäßig dickwandiges, aber hochwertigen Werkstoff sparendes Teil, das auf seiner Unterseite :die bei Stühlen erwünschte, ebene Anschlußfläche hat.In contrast, according to the invention: the seat plate made of a veneer, z. B. from wood, from a polymethacrylic acid ester or another heat = plastic Mass, or a sheet of plywood and. one made from wood chips and a binder existing pressed material insert 'produced. The result is a proportionate thick-walled, but high-quality material-saving part that is on its underside : has the flat connection surface desired for chairs.

Das. Furnier kann viel dünner sein als bei :den üblichen Sitzplatten; die Einlage bzw. Auflage verhindert, idaß auf kleinster Fläche auf die Sitzplatte einwirkende Überlastungen @dias Furnier bleibend verformen bzw. beschädigen.That. Veneer can be much thinner than: the usual seat panels; the insert or support prevents that on the smallest area on the seat plate Acting overloads permanently deform or damage the veneer.

Die Sitzplatte kann in der Weise hergestellt werden, daß das Furnier vorzugsweise vorgebogen, in die zum Herstellen nötige Preßform eingelegt, daraufhin die Einlage als Schüttgut eingebracht, letztere verdichtet und: schließlich das Ganze so lange in der Preßform belassen wird, bis das Bindemittel fest geworden ist. Inder Zeichnung sind Ausführungsbeispiele dargestellt.The seat plate can be manufactured in such a way that the veneer preferably pre-bent, inserted into the mold required for production, then the insert introduced as bulk material, the latter compacted and: finally that The whole thing is left in the mold until the binder has solidified is. Exemplary embodiments are shown in the drawing.

Abb. ir und 2 zeigen Querschnitte, während Abb. 3 den - Grundriß einer Sitzplatte veranschaulicht.Fig. Ir and 2 show cross-sections, while Fig. 3 shows the - plan of a Seat plate illustrated.

Das Furnier z bzw. die Furniere a und 2 haben die aus. Holzspäne und einem an sich bekannten Bindemittel bestechende Einlage bzw. Auflage 3. Letztere kann im Bedarfsfall noch durch ein Holzgerippe versteift sein. An :der Erfindung ärndert sich .auch nichts, wenn ,die Sitzplatte :durch eine Rückenlehne oder durch Armstützen verlängert wird.The veneer z or the veneers a and 2 have the from. Wood chips and a per se known binding agent inlay or overlay 3. The latter If necessary, it can be stiffened by a wooden frame. To: the invention doesn’t change, if the seat plate: through a backrest or through Armrests is extended.
