Abstract

Ein Holzstuhl in Massivbauweise besitzt eine an Holmen (20) befestigte Rückenlehne. Die Holme (20) sind zwischen der Sitzfläche (16) und der Lehne (22) geteilt und die Trennfuge (23) ist durch Federstäbe (28) überbrückt. Zur Verbesserung der Dauerhaltbarkeit bei einfacher Fertigung wird vorgeschlagen, daß in jeweils beiden Holmhälften (30, 32) Aufnahmebohrungen (34, 36) vorgesehen sind, die einen an der jeweiligen Stirnfläche beginnenden ersten Bereich (38, 40) größeren Durchmessers von wenigstens 25 mm Länge und einen daran anschließenden zweiten Bereich (42, 44) engeren Durchmessers aufweisen, in welchem ein Ende des jeweiligen Federelements (28) auf einer Länge von wenigstens 25 mm befestigt ist. Die Krafteinleitung erfolgt damit nicht mehr im kritischen Bereich des Hirnholzes und der Abstand der Einspannstellen des Federstabes (28) erlaubt den Einsatz stabilerer Federelemente (28).

Figure 00000001
A wooden chair in solid construction has a backrest attached to bars (20). The bars (20) are divided between the seat surface (16) and the backrest (22) and the parting line (23) is bridged by spring bars (28). To improve the durability with simple manufacture, it is proposed that in both spar halves (30, 32) receiving bores (34, 36) are provided which have a first area (38, 40) of larger diameter and at least 25 mm in length beginning at the respective end face and have an adjoining second region (42, 44) of narrower diameter, in which one end of the respective spring element (28) is fastened over a length of at least 25 mm. The force is no longer applied in the critical area of the end grain and the distance between the clamping points of the spring bar (28) allows the use of more stable spring elements (28).
