Definitions
- the present invention relates to a chair comprsing a seat a backrest and side portions functioning as legs.
- 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.
- 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.
- a further 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 spctor or other places where there are high demands for hygiene, for example in the food industry.
- Fig. 1 shows a chair according to the invention in a front view
- Fig 2 show the same chair in side view
- Fig. 3 shows a chair according to the invention in perspective view
- Fig. 4 shows a work piece, from which a chair can be manufactured, and with a contour of the final chair indicated with a dash and dot line.
- 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, weighging 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 cheeper to produce since the provision of such gripping means will increase the costs of production.
- the chair according to the invention is manufactured of veneer, but other materials are also possible choices. Where it comes to outdoor use, the chair can be made from for example glass-fibre armoured form materials, of a spot welded wire netting, or of a metal plate, for example aluminium.

Abstract
Chaise comportant un dossier et une assise fabriqués en une pièce à partir d'un matériau de préférence anisotrope ou laminé, d'une épaisseur généralement uniforme, pouvant être dotée d'un châssis et de pieds, empilable ou pouvant être placée de manière à former une rangée de chaises, comportant un certain nombre de désavantages qui lui sont liés et qui se présentent à la fois pendant la fabrication et l'utilisation. Les désavantages relatifs à la fabrication sont essentiellement provoqués par le fait que la chaise doit être assemblée souvent avec un châssis lourd, accroissant les coûts de fabrication et augmentant le poids, si bien que la chaise est lourde et difficile à transporter. Les désavantages relatifs à l'utilisation sont essentiellement provoqués par la construction de la chaise: par exemple, il est difficile de fixer des vis en bois dans des pièces à usiner de faible épaisseur, l'utilisation de rivets ou de boulons en bois nécessite l'usinage de la surface supérieure de la chaise et la chaise, en raison des joints et des coins est souvent difficile à nettoyer. Ces désavantages sont résolus efficacement par le fait que les pieds (3) sont formés par des extensions dirigées latéralement de la surface d'assise (1), lesdites extensions étant pliées selon une direction opposée par rapport au dossier (2) et par le fait que l'assise (1), le dossier (2) et les pieds (3) sont fabriqués à partir d'une seule pièce à usiner. Grâce au design des pieds (3), on obtient un certain nombre d'avantages relatifs au montage, au prix, à l'utilisation du matériau, au poids et au transport.Chair comprising a backrest and a seat made in one piece from a preferably anisotropic or laminated material, of generally uniform thickness, which can be provided with a frame and legs, stackable or which can be placed so as to form a row of chairs, with a number of disadvantages associated with it and which arise both during manufacture and use. The manufacturing disadvantages are mainly caused by the fact that the chair has to be assembled often with a heavy frame, increasing the manufacturing costs and increasing the weight, so that the chair is heavy and difficult to transport. The disadvantages relating to the use are mainly caused by the construction of the chair: for example, it is difficult to fix wooden screws in thin workpieces, the use of wooden rivets or bolts requires Machining of the upper surface of the chair and the chair, due to the joints and corners is often difficult to clean. These disadvantages are effectively resolved by the fact that the legs (3) are formed by laterally directed extensions of the seat surface (1), said extensions being folded in an opposite direction relative to the backrest (2) and by the fact that the seat (1), the backrest (2) and the legs (3) are made from a single workpiece. Thanks to the design of the legs (3), a certain number of advantages are obtained relating to assembly, price, use of the material, weight and transport.
