Definitions
- the present invention relates to a chair comprising a seat, a backrest and side portions functioning as legs according to the first part of claim 1.
- DE-A-2 029 520 relates to a chair formed by a single piece of a material such as Nylon@. Reinforcing flanges are provided along the back, seat and side pieces. There is also a reinforcing valley provided along the transition portion between the back and the seat of the chair. Separate feet are attached to the side pieces by means of screws.
- US-A-2670787 relates to a chair having seat and backrest formed from one single piece of laminated wood and legs which are fastened separately to the sides of the seat.
- the object for the present invention is thus to provide a chair of the above mentioned type, with which the above mentioned disadvantages effectively are overcome by the features of the characterising part of claim 1.
- the chair is manufactured through bending of a piece of a flat material, which piece of flat material preferably is anisotropic or laminated and has a generally uniform thickness.
- a piece of flat material preferably is anisotropic or laminated and has a generally uniform thickness.
- the shape of the work piece i.e. the veneer before glueing and pressing
- the weight is reduced correspondingly, which also is of importance for transport or keeping in stock.
- the legs can however be convexly curved to form rockers.
- Afurther advantage of the chair according to the invention comes from the fact that with the use of one single material, is achieved both a uniform wear, a robust chair and a homogenous aftertreatment of the chair, in that for example it is not necessary to use a number of types of varnish for varnishing for example wood and metal respectively.
- time is saved, and the costs during manufacture are further reduced, and the final product offers to the consumer a uniform upper surface, which due to the compact design of the chair is easy to keep clean. Consequently the chair is suitable for use within the hospital sector or other places where there are high demands for hygiene, for example in the food industry.
- a chair manufactured from a work piece 4 of multi layer veneer, for example cross-veneer has a seat surface 1 and a backrest 2 and legs 3, formed by bending sideways directed extensions of the seat surface 1.
- the extensions of the seat surface are bent a little less than 90°, for example 80° to 85°, relative an imaginary line between the highest points of the seat surface, but with the stability of the chair in mind it is also possible to bend these extensions less than 80°.
- Fig. 4 the contour of the final chair is indicated on the work piece 4 with a dashed and dotted line. It is here evident that the loss of material during the manufacture of the chair is relatively small and approximately amounts to a few percent.
- the material for manufacture of the chair according to the embodiment described is essentially veneer, namely a flat cut top veneer with a thickness of for example 0.7 mm and an inlay veneer of for example sliced beech veneer with a thickness of for example 1 mm.
- two layers of top veneer and six layers of inlay veneer are used, said layers are arranged such that the direction of the veins in the veneer layers I, III, IV and VI essentially lay parallel with the symmetry axis of the work piece, while the veining in the layers II and V lay perpendicular to the symmetry axis.
- the weight of the final chair amounts to little less than 6 kg, which constitutes a weight reduction of about 30% compared to previously known chairs, weighing at least 9 kg.
- the chair according to the invention can be produced without being provided with particular gripping means or cut-in portions, such means being necessary with heavier chairs. This means that the chair at least becomes cheaper to produce since the provision of such gripping means will increase the costs of production.
