Technical Problem The technical problem to be solved by the invention is how to design a chair of the above-mentioned known shape, which is preferably produced of solid wood and foreseen for the use in restaurants as a dining chair and in other public areas as a conference chair, so that it will be possible to stack the chairs in order to reduce the storage area needed.

Prior Art As stacking chairs mainly metal stacking chairs are known, whose legs or supports are shaped in such a manner that particular parts thereof fit to each other at stacking. With chairs having a classical form of the front and rear legs and spindles under the seat made of solid wood, it has not even been tried to design stacking types. The general opinion has been that any redesigning enabling chair stacking would result in making the chair weaker and thus reducing the sturdiness such a chair is known for if the chair form was to be preserved.

Nevertheless, there has existed a need for a stacking type of such classically shaped chairs so as to allow a quick changement of the current purpose of a room by a temporary removal of these chairs to a storeroom where shortage of space is to be expected.

Solution to the Technical Problem According to the present invention, the described technical problem is solved by changing the position of the spindles between the legs under the seat plate and the space arc of the rear legs, whereby the aesthetic appearance of the chair is not changed in comparison to the known unstackable chair.

The essence of the invention will be explained in more detail by describing a preferred embodiment and the enclosed drawing showing in Fig. 1 a chair according to the invention in perspective view, and Fig. 2 several chairs according to the invention stacked one upon another.

The chair is made of straight vertical front legs 1, arched rear legs 2 which are extended upwards over a seat 3 so that on the upper parts of the rear legs any kind of a back 4 is placed, the front legs 1 are connected under the seat 3 by a spindle 5, whereas the rear legs 2 to each other as well as each rear leg 2 to the respective front leg 1 are all together connected by a curved rear lower spindle 6. The seat 3 is preferably executed as a rectangular plate with an arch-formed rear edge. The front legs 1 are placed in the corners of the seat 3, the rear legs 2 run by the arched edge of the seat 3 and are also fixed thereto.

In the area of the seat 3 the rear legs 2 are bent rearwards and outwards to such an extent that a distance A between the front leg 1 and the respective rear leg 2 in the place of the curved rear lower spindle 6 lying approximately at one half of the height of the front leg 1 and paralelly to the seat 3 amounts to at least as much as the distance between the front leg 1 and the rear leg 2 in the place of the seat 3 increased for two thicknesses B of the front leg 1. The curved rear lower spindle 6 connects each front leg 1 and rear leg 2 and at the same time the rear legs 2 together.

The chairs according to the invention are stacked in such a manner that the curved rear lower spindle of the upper chair lies on the seat edge of the lower chair while the front leg of the upper chair lies in front of the front leg of the lower chair, whereas the rear leg of the upper chair lies on the outer side of the lower chair. It is clear that a person skilled in the art can also design, with regard to the shape, other embodiments of the chair or of its parts as depicted in the drawings and described without avoiding the characteristics of the invention defined in the patent claim.
