Definitions
- the invention relates to a chair, in particular a row chair, with a frame which consists of two essentially U-shaped frames made of bar material arranged on both sides of the chair, the front and rear legs and the lower legs connecting the legs Form skids, a seat plate supported on the frame and a backrest.
- Chairs of this type are known in various embodiments.
- Steel is generally used as the bar material, which offers the necessary strength, so that the bars can be made relatively thin.
- the chairs are relatively simple and can be used as row chairs for changing seating in differently used rooms.
- the seat plate and / or backrest can consist, for example, of thin plate material, such as plywood or plastic.
- a disadvantage of these chairs is that the seating comfort is relatively low.
- the object of the invention is to improve a chair of the type mentioned at the outset with simple, inexpensive means with regard to the seating comfort provided.
- the seat plate is made of a flexible material and is pulled down in an arc at the front edge to the front legs and is firmly connected to the front legs in that the backrest with the back - Tight edge of the seat plate is firmly connected, that the rear legs in the upper area are angled forward and / or inclined forward overall and that an intermediate piece is provided which at the front end in a ner transverse axis is pivotally connected to the upper end of the rear legs and further back to the underside of the seat plate and the backrest.
- Such a chair has only one axis, namely the transverse axis at the upper end of the rear legs, which establishes the connection with the intermediate piece.
- a chair mechanism usually requires at least three transverse axes for connecting the seat plate and the backrest to the frame and to one another. Swivel axes of this type require an increased design effort and require a certain susceptibility to wear, so that the possible reduction of the number of transverse axes to one axis in the present case results in both a reduction in production costs and an improvement in wear behavior.
- further axes are dispensed with, among other things, because the flexibility of the seat plate itself is exploited.
- This flexibility and flexibility can be increased by cutting parallel slots into the seat plate which end at a distance from the front and rear edges of the seat plate.
- the rear legs Since the rear legs are bent inwards, if necessary also inclined forward, they can springily deflect forward and downward when loaded from above or obliquely from above and behind.
- the elasticity of the steel material of the legs is therefore also used for the spring action of the chair without the need for corresponding joints.
- the above-mentioned deflection movement occurs particularly when the backrest, which is firmly connected to the rear edge of the seat plate, is loaded by the user of the chair being put back, since the bending of the rear region of the seat plate and the backrest resulting therefrom becomes obliquely forward and downward force on the intermediate piece connected to the legs.
- the legs can be connected continuously via sections of the rod material used, so that the frame may represent a closed frame.
- the front, downwardly bent edge of the seat plate can be firmly clamped onto the bar material section above the front legs.
- the rear, transverse Section of the bar material can be used as a pivot axis for the intermediate piece.
- the only figure is a perspective view of a chair according to the invention.
- a chair according to the invention has a frame 10, which essentially consists of two corresponding, overall U-shaped frames 12, 14.
- the two frames form front legs 16, 18, rear legs 20, 22 and lower runners 24, 26, which connect the legs on both sides.
- the front legs 16, 18 are continuously connected to one another at their upper ends by a transversely directed section 28 of the rod material.
- the rear legs 20, 22 are connected via a transverse section 30 of the bar material.
- the rod material thus forms a closed material ring overall.
- the rear legs 20, 22 are angled obliquely forward and upward in their upper end regions, or are inclined obliquely forward overall.
- a seat plate 32 extends from the transverse section 28 connecting the legs 12, 14 at the upper end with an arcuate bend forward and upward.
- the seat plate 32 is connected to the transverse section 28 of the rod material with the aid of a clamping strip 34 which is U-shaped in cross section.
- an intermediate piece 36 is pivotally attached, which extends backwards and slightly upwards.
- the transverse section 30 embodies the pivot axis of the intermediate piece 36.
- the upper side of the essentially plate-shaped intermediate piece 36 connects the lower side of the seat plate 32 at a distance to the section 30.
- the rear end of the intermediate piece 36 which is hidden in the drawing, is firmly connected to the inner surface of a curved, shell-shaped backrest 38. bound with which the rear end of the seat plate 32 is firmly connected in a manner not shown.
- the deformation movements of the chair therefore essentially occur due to the inherent elasticity of the plate-shaped material of the seat plate 32 and the backrest 38 and of the rod material of the legs. Only one pivot axis is required, which is formed by the rear, transverse section 30 of the rod material.
- end stops e.g. Rubber buffers may be provided.
