Abstract

The chair has a tubular arm rest (28A) which is z-shaped in plan view and has a concave central section (30A). This allows it to be connected to the opposite arm rest (28B) of an adjacent seat which has a corresponding convex section (32A).

Description

The invention relates to a chair comprising a seat element which is mounted on a chair frame, on which a plurality of chair legs are formed, on both sides of the seat element in each case an armrest having an armrest bracket, and a coupling device for concatenation with a chair of the same design.

Such chairs are known in practice and can be used in particular for building chained rows of chairs. For example, known such chairs as a coupling device each have a laterally formed, projecting, hook-like tab which engages in the concatenation with a chair of the same type in a receptacle of this chair, which is also formed laterally next to the seat member. However, such a coupling device disturbs the appearance of the chair, especially if this alone, that is to be used unchained.

The invention has for its object to provide a chair of the aforementioned type, on the one hand meets the requirements of panic security requirements and on the other hand provides an improved over the prior art described above appearance.

This object is achieved by the chair with the features of claim 1.

The invention therefore relates to a chair which has a seat element which is mounted on a chair frame on which a plurality of chair legs are formed, on both sides of the seat element in each case an armrest which has an armrest bracket, and a coupling device for linking to a chair of the same design a row of chairs. The coupling device is formed by the Armauflagebügeln, the each bent relative to a vertical chair longitudinal center plane such that when concatenating the chair with a chair of the same type of Armauflagebügel a corresponding Armauflagebügel of an adjacent chair engages under the other and Armauflagebügel a corresponding, the one Armauflagebügel corresponding Armauflagebügel an adjacent chair of the same design overlaps.

The concatenation of the chair according to the invention thus takes place on the armrests, by the fact that their Armauflagebügel are interlocked. For this purpose, the two Armauflagebügel are designed differently such that the support bracket on one side of the chair and the Armauflagebügel on the other side of the chair have engageable forms with each other. This makes it possible that for concatenating the chairs of the chair with the cross Armauflagebügel must be raised only slightly or the chair is tilted laterally with the underarchive Armauflagebügel and pushed under the cross Armauflagebügel so that the chairs are chained together. The concatenation can be done solely by the Armauflagebügel without further components, so that the chair of the invention provides an optimized appearance even when not chained.

In a preferred embodiment of the chair according to the invention, the one arm support bracket comprises a front end portion and a rear end portion, which are concavely bent with respect to the seat surface, and the other arm support bracket comprises a front end portion and a rear end portion, respectively with respect to the seat surface are bent convexly. Due to the simple bending of the end regions of the Armauflagebügel the possibility of entanglement of the Armauflagebügel is thus possible in a simple manner, wherein the corresponding end portions in the concatenated state of two chairs preferably at least partially lie positively against each other.

The Armauflagebügel can each have an at least approximately round cross section or an angular cross-section.

Preferably, the Armauflagebügel are each arranged at least with an end portion of the chair frame. It is conceivable, the Armauflagebügel in one piece with the Chair frame to manufacture or the Armauflagebügel as a separate component, for example as a plastic injection molded form, which is fixed to the chair frame.

To optimize the panic security of chained chairs according to the invention, in a preferred embodiment with respect to a vertical chair longitudinal center plane on an outer side of the chair at least one Arretiervorsprung arranged and on the other outer side at least one corresponding receptacle for engagement of the Arretiervorsprungs an adjacent chair of the same type in concatenation Chairs arranged.

The locking projection and the receptacle can each be arranged integrally on the Armauflagebügel or be formed on the chair frame or on one of the chair legs.

The chair according to the invention may be designed as a rack stacker, so that it is stackable on the chair frame. For example, the chair frame on both sides of the seat in each case two towards the ground diverging chair legs, at the upper ends of the respective Armauflagebügel is arranged.

Further advantages and advantageous embodiments of the subject matter of the invention are the description, the drawings and the claims removed.

In the drawing, a chair 10 'linked chair 10 is shown, which is designed as a so-called frame stacker and a chair frame 12 which forms on both sides of a chair longitudinal center plane two chair legs 14A and 14B and 16A and 16B. The chair legs 14A and 14B or 16A and 16B of a pair of chair legs run apart in the direction of the ground. The chair leg pairs 14A, 14B and 16A, 16B are connected to each other via transverse struts 18 and 20. On the transverse struts 18 and 20, a seat member 22 is mounted, which consists of a seating area 24 and a backrest 26. The chairs 10 and 10 'are identical.

Furthermore, the chair 10 or 10 'on both sides of the seat member 22 each have a bow-shaped armrest which forms a Armauflagebügel 28 A and 28 B, which has a substantially round cross-section and each end portions 30 A, 30 B and 32 A, 32 B on the upper ends of the respective chair legs 16A, 16B and 14A, 14B is placed.

The chair 10 can, as can be seen from the drawing, be concatenated with other chairs 10 'of the same type. The concatenation of the chairs 10 and 10 'via a coupling of Armauflagebügel 28 A and 28 B. For this purpose, the Armauflagebügel 28 A and 28 B are entangled with each other in such a way that the chairs 10 and 10 'essentially only in common in the form of a chair row can be moved or moved.

To allow the armrest bracket 28A of the chair 10 'to be interlaced with the armrest bracket 28B of the chair 10, the end portions 30A and 30B of FIG Fig. 1 right armrest bracket 28B bent relative to the seating area 24 concave, that is, the curvature of the end portions 30A and 30B points toward the bottom. On the other hand, the end portions 32A and 32B of FIG Fig. 1 On the left armrest bracket 28A bent relative to the seating area 24 convex, that is, the curvature of the end portions 32A and 32B is opposite to the curvature of the end portions 30A and 30B of the armrest bracket 28B. This makes it possible that the Armauflagebügel 28B of the chair 10, the Armauflagebügel 28A of the chair 10 'at least partially positively engages under the Armauflagebügel 28A of the chair 10' overlaps the Armauflagebügel 28B of the chair 10 at least partially positively. Here, the substantially horizontal portions of the adjacent Armauflagebügel 28 A and 28 B are arranged at the same height. The Armauflagebügel 28 A and 28 B, which are bent relative to a vertical chair longitudinal center plane to the outside, so form Verketterbügel, which abut each other.

As in particular the Figures 5 and 6 can be seen, the chair 10 and 10 'relative to the vertical chair longitudinal center plane at its in Fig. 1 on the left outside a nose-like locking projection 33, which may also be designed in the manner of a Ronde and engages in the concatenated state in a formed on the right outer side of the adjacent chair 10 and 10 'recess 34. In the present case, the locking projection 32 is formed on the right front chair leg 16A, whereas the receptacle 34 is disposed on the left front chair leg 14A. At the right rear chair leg 16B, a corresponding locking projection is arranged. At the left rear chair leg 14B, a corresponding, corresponding to the locking projection receptacle is arranged.

As in particular the FIGS. 4 to 6 It can be seen, the concatenation of the chairs 10 and 10 'can be such that the chair 10' is raised and tilted relative to the chair 10 so that the Armauflagebügel 28A of the chair 10 'can be brought over the Armauflagebügel 28B of the chair 10. Subsequently, the chair 10 'lowered again and placed on the floor, so that the respective cranked Armauflagebügel 28 B and 28 A are interlocked with each other and immerse the locking tabs 33 of the chair 10' in the receptacles 34 of the chair 10.
