Abstract

Convertible upholstered furniture. The piece of furniture has upholstered elements 1 to 6, which can be removably connected to each other and consisting of seat upholstery 10, 12, 14, 16, 18, 20 and modular backrests 11, 13, 15, 17, 19, 21. Seen from above, the seat pads are in the form of spherical triangles with the sides of the same size, two sides a, c being convex and the third side b being concave. The backs can be removably connected to at least one of the convex sections of the seat padding. Application: convertible and / or transformable armchairs and sofas, with modular elements.

Description

The invention relates to a convertible upholstered furniture, comprising

  padded elements which can be detachably connected to each other and consist of cushions or padding of seats and backrests, the seat padding having, when

  we look at them from above, the shape of spherical triangles

  curved sides, the absolute values of the curvature rasyons of the sides of the triangles being equal, and the folders which can be connected in a manner -movible to

  at least one of the curved sides of the seat upholstery

  and adapted to the curvature of seat upholstery. Upholstered furniture of nature mentioned at the beginning of this paper is known and is described, for example, in US Pat. No. 3,955,850. When viewed from above, seat upholstery essentially has a semi-shaped shape. -circular with two concave concave sides of known padded elements. Concave sides of seat upholstery have a shape

  complementary to that of the convex sides' semi-circular

  seat cushions, so that the seat cushions can not be combined with the

  to each other only in a limited way.

  Starting from the above state of the art

  whereas, the problem underlying the invention is to develop the upholstered furniture in question,

  without unreasonable complexity of structure or

  truction, so that it is possible, with a smaller number of seat and backrest paddings, to assemble and mount a significantly larger number

of different upholstered furniture.

  According to the invention, the problem is solved

  if posed, because the side walls of the triangles are large and that, always, both sides have a convex curvature while the third side

is concave.

  The shape of the elementary units, or

  modules, upholstered furniture is therefore chosen

  The chairs or seats, or sofas, or sofas formed from these modules have irregular shapes. Thus, the edges of the seats are curved towards the user or to deviate from it. It is also possible to form a bed or couch which, when viewed vertically or from above, has a circular surface surrounded by an annular backrest. A particularly advantageous form of the invention provides that the radii of curvature of the sides

  concave- files correspond to the cour-

  the convex sides of the seat upholstery.

  A particularly advantageous form of the invention also provides, in the case of a padded furniture having several seat cushions and several backrests, at least two folders each time have at least a small plane and vertical side, cutting the sides concave files at an angle

different from 90O.

  Some examples of the realization of the invention

  are described in more detail below, in relation to a

  schematic representation shown in the drawings

  FIG. 1 shows a convertible upholstered furniture, comprising padded elements 1, 2, 3, 4, 5 and 6, which can be connected to one another in a removable manner and consist of padding of seats 10, 12, 14, 16, 18 and 20 and in folders 11, 13, 15, 17, 19 and 21. Seat upholstery 10 to 20

  possess, when viewed from above, the form of

  spherical angles, such as the a, b and c sides of the

  They have equal lengths and each time two sides a and c have a convex curvature, while the third side b is concave. The folders 11 to 21 can thus be connected, removably, to the

  convex sides a, c seats padding 10 to 20.

  The absolute values of the radii of curvature of sides a, b and c of triangles are equal. It is thus possible to arrange side by side and to assemble, in rows that do not have voids, each time two or more

  two upholstered seats 10, 12, 14, 16, 18, 20.

  The sides, which can be connected amo-

  seat cushions 10, 12, 14, 16, 18, 20,

  11, 13, 15, 17, 19, 21, are in the form of

  cellar and they are adapted to the convex sides a, b and c seat padding 10, 12, 14, 16, 18, 20. It

  Figure 1 also shows that courier spokes

  the concave sides of the files 11, 13, 15, 17, 19,

  21 correspond to the radii of curvature of the ribs con-

  vexes a, b, c seats padding 10, 12, 14, 16,

1i, 20.

  The upholstered furniture shown in Figure I consists of six padding seats 10, 12, 14, 16, 18, 20 and six folders 11, 13, 15, 17, 19, 21. The

  11 and 13 are thus of such a form that they

  lie two small vertical sides 30 and 31, which cut,

  at an angle C or different from 90c, the sides concave

  35 and 36 of the folders 11 and 13. An insert 66, wedge-shaped, is disposed between these folders 11

  and i3, so that in a vertical view from above, the

  1 and 13 have the shape of a ring. A piece of furniture -

  The padding shown in FIG. 1 also consists of six padded elements 1 to 6, which can be connected to each other by a conformation adjustment connection.

  and which consist in each case of upholstered

  age 10, 12, 14, 16; 18, 20 and in a folder 11, 13, 15,

17, 19, 21.
