A seat frame that can be converted from a chair to an armchair and vice versa

The invention relates to a chair or
the like in an armchair or the like
immutable seat frame and vice versa, whereby
the formation and combination of its skin parts give it special features
lend. '■

in this context ^, the term "chair" refers to a seat consisting of a supporting structure with legs, an actual, essentially horizontal seat 11 firmly connected to this supporting structure, and a backrest part also firmly connected to the supporting structure, and the term "armchair" refers to a seat constructed with essentially the same structure as the chair, but with the addition of a pair of armrests.

In modern home furnishings and especially in office furnishings, the supporting structure is usually made of chrome-plated or painted tubular metal or other

their materials, such as wood, plastic, aluminum, etc., wherein the seat part is attached to a horizontal frame firmly connected to the legs, and wherein the backrest is attached to parts of the supporting structure which extend from the rear legs above the horizontal frame.

In the armchair, in particular, the horizontal frame supporting the seat part has attachments in the area of the front legs, to which an end part of the armrest is attached, the opposite end part of which is attached to the end area of the extensions of the rear legs.

In the usual armchairs constructed as described above, the armrests are attached to the supporting structure by means of screws, nails, etc., whereby these fastening means do not allow the armrests to be quickly removed if desired.

The invention is therefore based on the object of designing a seat frame constructed in such a way that it can be converted from a chair into an armchair and vice versa in a simple and rapid manner and without the need to use any kind of tools.

These and other objects of the invention will be apparent to the industry expert from the following description and the patent claims.

The seat frame according to the invention contains, according to the generic term, a supporting structure, a horizontal frame firmly connected to this supporting structure, to which an actual seat part is fastened, a pair of front legs which lie outside the periphery of the seat part and are firmly connected to the horizontal frame, and a backrest part which is fastened to parts of the supporting structure which extend from the rear legs over the horizontal frame, and is essentially characterized in that it provides a pair of armrests which can be detachably connected to the supporting structure, namely by coupling components provided at their ends to the corresponding upper end parts of the front legs and the parts extending from the rear legs, without any use of screws or similar fastening means.

In the following, the invention is described with reference to the accompanying drawings - by way of example but not

limited - explained in more detail. They show:

Fig. 1 the seat frame in the "chair" version;

Fig. 2 the seat frame in the "armchair" version;

Fig. 3 the removal or installation phase of an armrest from or into a frame according to the invention, and

Fig. 4, in an enlarged view, the preferred means for installation of the armrest.

With reference to the figures, 1 designates a generic supporting structure made of tubular metal, which contains a horizontal frame 2 to which a seat part 3 is attached. 4 designates the front legs lying outside the periphery of the seat part 3, and 5 designates a backrest part which is attached to parts 6 extending from the rear legs 7 above the horizontal frame 2.

According to the invention, the upper end parts 8 of the front legs 4 and the upper end parts 9 of the extended parts 6 can be closed by a removable plug (not shown) which can be inserted into a cavity defined by the tubular metal element forming the legs and the extended parts.

As shown in particular in Fig. 3 and Fig. 4, the armrests 10 have a pin 11 at each end, which can be releasably inserted into a corresponding cover 12, whereby this cover 12 is pressed into a cavity defined by the front legs 4 and the extended parts 6.

In a further embodiment not shown, the Δελλα 11 is replaced by a hole provided at each end of the armrests 10, whereby this hole can be plugged onto the corresponding end part of the front legs 4 and the extended parts 6 from the outside.

From the above description, it therefore appears clear that the seat frame according to the invention can be converted from a chair into an armchair and vice versa in a simple and rapid manner and without the need for special tools.
