Description

The invention relates to a removable chair, further a set with such a chair.

Usually chairs are inevitably - if necessary, using tools - disassembled because they had to be mounted before or transported for space or price reasons as a kit and delivered.

A chair usually has a seat for sitting on a person, and at least four chair legs for supporting the seat. Furthermore, the chair has a chair back, against which the seated person can lean against the back and possibly lateral armrests.

DE 299 212 51 U1 discloses a modular armchair comprising a seat, a backrest and two armrests, the backrest being removably attached to the back of the seat. This facilitates the Aufpolstern, since not the entire heavy chair must be handled.

JP 2002 045 256 A discloses a chair with an integrally formed base with seat on which rear or side armrests or backrests can be attached.

The possibilities of adapting or repairing these seats after acquisition by the owner on the basis of changed requirements, design ideas or are not addressed in the above-mentioned prior art and greatly limited by design. The prior art is more concerned with the manufacture of the chairs.

It is therefore an object of the present invention to provide an improved chair and a set with such a chair.

This object is achieved by means of a chair having the features of the main claim. A set with such a chair is the subject of the independent claims. Advantageous embodiments are the subject of the dependent claims.

The disassemblable chair according to the invention initially has a seat for sitting on a person, which chair leg restraining means for individually releasably securing at least four individual chair legs comprises. At least four chair legs are attached to the respective Stuhlbeinbestigungsmitteln individually. Thus, individual selected or all chair legs can be exchanged, for. B.: If only one chair leg damage or to change or individualize the appearance of the chair. The same applies if, in addition, the seat of the Lehnenbestigungsmittel for releasably securing a chair back and a chair back is attached to the seat on the Lehnenbestigungsmittel. Thus, all parts are interchangeable, even if necessary, the seat, z. B .: against a wider, reinforced, narrower, with a different design / color / seating comfort and / or the like.

Basically, the seat can be constructed arbitrarily, provided that the two functions "securing the chair legs or chair backs" are possible. Special design variety arises, however, when the seat has a seat for sitting a person, as well as necessary for the function of the chair, attaching the chair legs and attaching the chair back stability-giving structure. As a result, an optimal material or design can be used for each function, without having to compromise. For example, a stable metal frame may be connected as a structure with a seat shell forming the seat. Preferably, the seat is separable and therefore interchangeably connected to the structure to allow for more variants or a simplified repair replacement.

Alternatively and in terms of manufacturing technology, the seat is made in one piece from the seat surface and the stability-giving structure. This can also go so far that these two components form the seat inseparable, so z. B .: a composite stability for the stability-giving structure and the seat. It may also be a single material / composite material forming the seat with stability-giving structure, in particular by appropriate stability-imparting shape, z. B .: with ribs, reinforcements, etc.

Preferably, a support element is provided, which is inserted under or in the seat and which supports the seat. Thus, in exceptional cases, particularly heavy persons of the chair can be exceptionally strengthened. It is therefore not all chairs in a room designed for the heavy load and therefore heavier and more expensive, but flexible only the really to be reinforced chair with the support element is provided if necessary. Otherwise, a different chair would have to be provided for the heavyweight person, which could possibly be perceived as unpleasant by the person. In this case, the particularly stressed side area of the seat is preferably reinforced. In particular, therefore, the support element has a V-shape. Flexible is provided according to the invention for a particularly heavy people suitable seating, which in particular supports the pelvic cooking and thus reduces the pressure acting on the sides seat pressure, where z. B. the padding would most likely tear.

Conveniently, the stability-providing structure comprises the chair leg restraints and Lehnenbestigungsmittel. Particular preference is given to the stability of the connection with simultaneous ease of use by the end user, who is not technically versed in the rule: Preferably, therefore, the Stuhlbeinbestigungsmittel and / or Lehnenbestigungsmittel are designed such that the user with conventional tools, especially screwdriver, wrench , which can perform replacement of a chair leg or a chair back.

In continuation of this idea, it is suggested that the Stuhlbeinbestigungsmittel and / or Lehnenbestigungsmittel are designed such that tool-free replacement of a chair leg or a chair back can be performed. Such fasteners are variously known in the art and naturally always represent a compromise between ease of use and security against accidental release dar. Only exemplary a lever-operated clamping device, a bayonet or more generally a sequence of movements about different axes and / or in the direction of different axes are called , wherein preferably a spring force can act in the direction of a latching, which prevents unwanted leaving this engagement position.

Now, if a set is provided directly with an additional chair leg or several additional chair legs, which or which in comparison to the chair legs fixed to the removable chair is fastened to the respective chair leg rest means are, wherein the additional or the additional chair legs in shape and / or color deviates from the chair legs exchanged on the removable chair, the user can produce different chairs to taste, occasion, season or the like. He therefore does not have to provide storage space for the alternative chairs, since he can only produce these divergent chairs by replacing his legs.

Analogously, the same applies with respect to an additional chair back, which is attachable to the Lehnenbestigungsmitteln in exchange for the chair chair attached to the removable chair, the additional chair back in shape and / or color of the demountable chair attached and exchanged chair back deviates.

• – Demontage von mindestens einem der vier einzelnen Stuhlbeine von dem Sitz an den entsprechenden Stuhlbeinbestigungsmitteln;
• – Bereitstellen von mindestens einem zusätzlichen Stuhlbein, welches im Austausch zu dem demontierten Stuhlbein geeignet ist zur Befestigung an den Stuhlbeinbestigungsmitteln des Sitzes geeignet ist, wobei das zusätzliche Stuhlbein in Form und/oder Farbe von demontierten Stuhlbein abweicht;
• – Befestigen des mindestens einem zusätzlichen Stuhlbeines an den Stuhlbeinbestigungsmitteln des Sitzes;

According to the invention, therefore, the chair or set according to the invention can be changed in appearance with the following steps;

• - disassembly of at least one of the four individual chair legs from the seat to the corresponding chair leg restraints;
• - Providing at least one additional chair leg, which is suitable in exchange for the disassembled chair leg suitable for attachment to the chair leg rest means of the seat, wherein the additional chair leg deviates in shape and / or color from disassembled chair leg;
• - Attaching the at least one additional chair leg to the chair leg rest means of the seat;

• – Demontage der Stuhllehne von der Sitz an dem entsprechenden Lehnenbestigungsmittel;
• – Bereitstellen von einer zusätzlichen Stuhllehne, welche im Austausch zu der demontierten Stuhllehne geeignet ist zur Befestigung an dem Lehnenbestigungsmittel des Sitzes geeignet ist, wobei die zusätzliche Stuhllehne in Form und/oder Farbe von der demontierten Stuhllehne abweicht;
• – Befestigen der zusätzlichen Stuhllehne an dem Lehnenbestigungsmittel des Sitzes.

In an analogous method for changing the appearance of a chair or set, these steps are suggested:

• - disassembly of the chair back from the seat to the corresponding Lehnenbestmittels;
• - Providing an additional chair back, which is suitable in exchange for the dismantled chair back is suitable for attachment to the Lehnenbestigungsmittel the seat, the additional chair back in shape and / or color differs from the dismantled chair back;
• - Attaching the additional chair back to the Lehnenbestigungsmittel the seat.

Finally, preferably both methods can be combined to equally exchange the chair legs and backrests.
