Abstract

The furniture has a frame which comprises reciprocally tubular struts (3,4). A coupling unit is provided in the region of the tubular struts for linking with furniture portion. The coupling unit of the tubular struts is formed area by area in each case in such a manner related to the vertical plane bow-shaped and is outwardly bent. The bow-shaped outwardly bent portions (3a,4a) are engaged with under and/or behind other bracket-shaped outwardly bent portion of adjacent furniture portion.

Description

The invention relates to a piece of furniture with a furniture frame and at least one mounted on this element, wherein the furniture frame has tubular struts on both sides, and wherein in the region of the tubular struts a coupling device is provided for concatenation with a piece of furniture of the same type to a furniture series.

In row seating usually the use of so-called chain chairs is provided. In this case, the individual chairs are formed identically and have mutually corresponding connection elements with which the chairs can be coupled. As a result, the chairs are held in their desired position and thus in a certain order. The individual chairs have the disadvantage that the fasteners usually increase the manufacturing and assembly costs, since it is additional chair elements. In addition, the connecting elements are often perceived as disturbing.

Out DE 20 2009 007 655 U1 is a generic piece of furniture in the form of a chair is known in which the coupling device is formed by the Armauflagebügeln, each of which are bent relative to a vertical Stuhllängsmittelebene outward that the one Armauflagebügel engages in a concatenated state a corresponding Armauflagebügel an adjacent chair of the same type and the other Armauflagebügel in a concatenated state a corresponding, which overlaps a Armauflagebügel Armauflagebügel an adjacent chair of the same design over. This Armauflagebügel are inserted over end portions in chair legs of the chair frame, ie connect them together, they are preferably made of plastic. In such a chair, although no additional components for the coupling device are provided, but it is a special design of Armauflagebügel necessary soft items that must be connected to the chair legs in an additional assembly step. This solution is therefore still relatively expensive. In addition, the visual appearance is still in need of improvement.

Out DE 20 2007 009 977 U1 Another chair of this type is known, in which the coupling device is formed by additional components, namely laterally projecting hook-shaped connecting elements, which are connected to the chair legs and increase as additional components, both the assembly and the manufacturing cost and also provide an improved optical appearance ,

In contrast, the object of the invention is to provide a piece of furniture of the aforementioned type, which is inexpensive to produce and can be set up in the desired position without much work.

This object is achieved in a piece of furniture of the type described in the present invention, that the coupling device is formed by the tubular struts, which are bent in each case partially in relation to a vertical plane bow-shaped outward, that of a bow-shaped outwardly bent portion of the other bow-shaped over-bent area of an adjacent piece of furniture of the same type over, under and / or behind.

The concatenation of the piece of furniture is thus without additional components by a tubular strut of the furniture frame, which has corresponding bow-shaped (different) outwardly bent areas. Depending on the furniture design, the corresponding shaped tubular strut can be arranged vertically or horizontally in the floor area or above. In the production, therefore, since there are no additional components, only the furniture frame of a pipe or the like. Be bent, which greatly facilitates the production and also leads to a weight saving, since no additional components are required. Since the bow-shaped outwardly bent areas are an integral part of the furniture frame, they are visually hardly noticeable and do not affect the visual appearance of the furniture. Two pieces of furniture can be easily connected to each other by z. B. one of the two pieces of furniture is slightly raised and then brought into contact with the associated bow-shaped outwardly bent portion of the adjacent piece of furniture.

It is particularly preferably provided that the inclination of the bow-shaped outwardly bent regions relative to the vertical plane is selected so that adjacent pieces of furniture are interleaved for linking. In this way, it is possible that for concatenating the furniture, the piece of furniture with the overarching bow-shaped outwardly bent region z. B. only slightly raised and thereby has to be easily pivoted or tilted and then lowered, where it automatically returns to the starting position of the seat.

In order to achieve a particularly secure and perceptible for the user concatenation, it is preferably further provided that the bow-shaped outwardly bent regions are geometrically coordinated so that they are non-positively connected in a concatenated position. The geometric design can z. For example matched to each other that adjacent bow-shaped areas braced against each other. In this case, the interpretation can be chosen so that there is a point of resistance in the assembly of the linkage, so that it is noticeable to the user that the respective piece of furniture is locked to the adjacent piece of furniture.

It is particularly preferred that the tubular struts of the furniture frame having the bow-shaped areas are arranged in the foot region of the piece of furniture and form furniture runners. By providing the coupling device in the furniture runners on the one hand, a particularly simple concatenation is possible and on the other hand fall the bow-shaped outwardly bent areas optically almost not at all.

In this case, the tubular struts preferably merge integrally into vertical struts of the furniture frame, which makes it possible to produce the entire furniture frame from a single tubular starting material by bending deformation.

Basically, the above-described embodiment of the coupling device is sufficient to ensure a reliable concatenation of adjacent pieces of furniture. If, in the individual case of application, in particular for the protection of both the pieces of furniture and the floor surface on which the pieces of furniture are to be placed, it is desired that the runner area of the pieces of furniture be provided with rubber or plastic glides or feet, the further described below Design particularly advantageous.

Thus, it is provided in an advantageous embodiment that each horizontally extending tubular strut has at least adjacent to one side of the bow-shaped region an additional locking element which cooperates in linking position with a locking element of the adjacent piece of furniture.

These locking elements are preferably designed as form-fitting cooperating elements, d. H. their design is coordinated so that when concatenating adjacent pieces of furniture, the locking elements are coordinated so that they interact positively locking detent.

The locking elements are preferably designed as elastic clamping elements, for. B. rubber or plastic.

Additionally or alternatively, it can also be provided that the locking elements are designed as magnets.

The above-described piece of furniture is preferably designed as a chair, but it can, for. B. also be a table or a partition.

The invention is explained in more detail below by way of example with reference to the drawing. This shows in

An inventive piece of furniture in the form of a chair is generally with 1 designated. This chair 1 has in the embodiments a preferably of a single tube (preferably steel tube) bent chair frame 2 on. Here is the chair frame 2 designed so that it is on both sides in each case a lower runner-shaped horizontally extending strut 3 . 4 which in each case integrally in tubular vertical struts 5 . 6 respectively. 7 . 8th go over, which merge on the upper side in a manner not shown in horizontally extending recording struts, which with a 9 designated seat element with backrest 10 take up or carry.

The extent described chair is also referred to in the art as runner chair, the features described in more detail below are not only feasible in such a sled chair, but basically in all pieces of furniture with furniture frames, which have tubular struts that are for coupling to an identically constructed neighboring piece of furniture are suitable.

The chair shown 1 is suitable due to the features described below, to be concatenated or coupled with a chair of the same type and accordingly with other chairs to a chair row. It is essential that the coupling device integral part of the chair frame or more precisely the horizontal struts 3 and 4 is. These are the skid-shaped tubular pursuit 3 . 4 each region in such a way relative to a vertical plane, bow-shaped outwardly bent, that of a bow-shaped outwardly bent portion 3a the strut 3 the other bow-shaped bent outward area 4a the strut 4 over, under and / or behind the neighboring chair.

The inclination of the bow-shaped outwardly bent areas 3a . 4a compared to the vertical plane chosen so that adjacent chairs are pivotable into each other for linking. The sequence for connecting two identical chairs is in 1 to 4 shown. The identically designed chairs are included for the sake of clarity 1 (left chair) or 1' (right chair). This is the chair 1 already at its final position, while the chair 1' with the chair 1 connected or linked. This is the chair 1' gently raised and towards the chair 1 slightly tilted towards the vertical plane and then lowered until it stands on the floor surface. In this situation, the interconnected bow-shaped. areas 3a . 4a the corresponding skid-shaped struts 3 . 4 the chairs 1' . 1 in the in 5 and 6 illustrated linked position.

Particularly preferred may be provided that the bow-shaped outwardly bent areas 3a . 4a are geometrically coordinated with each other so that they are non-positively connected in a concatenated position.

To unlock the chairs, the chair becomes 1' simply in reverse order of 1 to 4 slightly swiveled and raised.

If it is desirable, a very particularly stable chaining of the chairs 1 . 1' to ensure an additional embodiment according to 7 ff. be provided. In this embodiment, each horizontally extending tubular runner-shaped strut 3 . 4 at least adjacent to one side of the bow-shaped area 3a . 4a provided with an additional locking element which cooperates in linking position with a locking element of the adjacent chair.

This locking element can be designed differently. In the illustrated embodiments, the locking elements are designed as elastic clamping elements. They are z. B. formed as rubber feet. These locking elements are preferably each on both sides of the bow-shaped area 3a respectively. 4a at the respective strut 3 respectively. 4 arranged, preferably plugged. Here are the locking elements for the strut 3 With 3b and for the strut 4 With 4b designated. The design of the two locking elements 3b respectively. 4b is preferably coordinated so that they can interact positively. In the embodiment according to 8a to 8c is the locking element 3b formed in a trapezoidal shape with a contact slope 3c and the locking element 4b parallelogram with an associated contact slope 4c ,

The formation of the slopes 3c respectively. 4c is such that the locking element 3b of the right chair 1' under the locking element 4b of the left chair 1 positively hooked. That's how the chair works 1' no longer simply be lifted upwards. The mounting sequence is in the 8a to 8c shown.
