THE PROCESS IS CHARACTERIZED IN THAT IT INCLUDES THE FOLLOWING PHASES: MAKING A CONSTRUCTION COMPOSED BY ONE OR MORE MESH ELEMENTS SHAPED IN SUCH A KIND TO CONSTITUTE, IN THEIR ENTIRETY, THE LARGEST PART OF THE DESIRED FINAL VOLUME OF THE FURNISHING COMPONENT; COVER AT LEAST PART OF THE CONTAINER WITH A PADDING LAYER OF SPONGIOUS MATERIAL UNTIL THE SAME COMPONENT REACHES THE DESIRED VOLUME AND SHAPE.

Description

! The present invention relates to a method for producing

  upholstered armchairs, couches and similar components as well as armchairs, couches and

  similar components obtained by said process.

  The method is characterized in that it comprises the following phases: producing a frame made up of one or more mesh elements shaped so as to constitute, as a whole, most of the desired final volume of the furnishing component; cover at least part of said frame with a layer of padding made of spongy material until

  that the component itself reaches the desired volume and shape.

  The main advantage of the process according to the invention is

  allow the realization of replacement furnishing components

  filled with high volume and at the same time having considerable elasticity and structural strength, for

a reduced cost price.

  We already know upholstered armchairs and couches formed by a rigid support frame of wood, metal, material

  plastic or similar, to which padding elements are made

  rubber or the like are fixed so as to give the

  armchair or sofa the desired shape, comfort and volume.

  This technique of realization, adopted everywhere, leads to realizations which are not very elastic in themselves, very

  heavy and therefore difficult to handle, as well as very

  space for storage and transport.

  In addition the combined cost of the rigid frame and the parts intended to form the desired volume, with the corresponding supports which

resulting is very high.

  The main object of the present invention is to provide a method allowing the production, at cost prices much lower than current costs, of armchairs, couches

  or the like having a high volume and at the same time an elas-

  considerable ticity, while maintaining sufficient structural rigidity. This object is achieved by means of a process for producing armchairs, couches and similar upholstered furniture components, characterized in that it comprises the phases of: producing a frame made up of one or more mesh elements shaped in such a way to train, as a whole,

  most of the desired final volume of the brewing component

  badly; cover at least part of said frame with a layer of padding made of spongy material until the same furnishing component reaches volume, comfort and

the desired shape.

  Achieving most of the volume and obtaining the elasticity characteristics of the armchair, sofa

  or the like by means of an electro-metallic wire frame

  SoudA, having its own characteristics of flexibility, has the consequence of limiting as much as possible the use of expanded material or in any case of padding, with excellent results as regards the elasticity and the comfort of the armchair, couch or the like.

  In particular, the use of electric wire mesh

  welded allows the choice of structural rigidity and flexibility

  optimal surface bility of the frame.

  For example, the use of shaped or round tubes

  having a diameter larger than that of the corresponding mesh

  laying with the edges and / or the lateral parts of the per-

  increases the structural rigidity of the frame itself, while the size of the surface development as well as the dimensions of the mesh of the mesh make it possible to determine the

  flexibility and elasticity of the support surfaces of the frame.

  The elements forming the frames of armchairs, couches and similar upholstered furniture components are fixed together by screws engaged in pairs of plates

  coupling fixed to each element.

  Each pair of coupling plates is fixed to a mesh of the mesh constituting the element, the plates being opposite and clamped together by means of a rivet having a threaded axial passage hole. This method of tightening makes it possible to fix the elements together in a very simple way and also serves to stuff and cover the elements themselves before they

are reciprocally fixed.

  In addition, an armchair, sofa or the like produced according to said method has exceptional characteristics of

lightness and economy.

  The process according to the invention will now be described more fully with reference to an armchair and a sofa obtained.

  according to said method and illustrated by way of non-limiting examples

  tifs in the accompanying drawings, in which: - Figure I is a perspective view of the frame of a couch with part of the backrest covered with a layer of padding; - Figure 2 is a perspective view of the frame of an armchair; - Figure 3 is a perspective view and a sectional view of the mesh constituting the frames of the couch and the chair illustrated in the preceding figures;

  - Figure 4 is a perspective view of the couch ob-

  held with the frame of Figure I; - Figure 5 is a perspective view of a couple

  of coupling plates in the reciprocating position

  before being attached to a mesh of the fence; - Figure 6 is a perspective view of the pair of

  coupling plates of the above figure fixed to a mail-

  the wire mesh; - Figure 7 is a sectional view of two elements fixed together by means of a screw engaged in coupling plates. Referring to the above-mentioned figures, the method according to the invention comprises above all the production of a frame

  in electro-welded wire mesh with an essential shape-

  similar to the final shape of the armchair or sofa and having a volume constituting most of the final volume of the

chair or couch itself.

  The frame is formed, preferably but not exclusively,

  by the mutual tightening of several nested elements cons-

  tituent respectively the file, the seat and the sides of the frame.

  This allows the chair or couch to be disassembled into several pieces which, together with the cushions, can be placed at least partly one inside the other to reduce the bulk and

  therefore storage and transport costs.

  Depending on its position and function in the frame, the element

  nested must have specific characteristics of

  structural rigidity and flexibility and super elasticity

  which can be obtained by modifying certain parameters

  meters of construction. For example, structural rigidity

  can be changed by changing the shape of the element,

  particular by introducing sharp angles or developments

  rounded, matching edges and / or edges

  lateral ties of the elements, tubes or circles having a larger diameter than that of the tubes or circles constituting

  the mesh, forming nested elements completely iron-

  més or with one or more open sides. Super flexibility

  can be modified by modifying the size of the mesh and / or the diameter of the circle constituting the mesh, by creating

  surfaces of considerable surface development or in inter-

  breaking said surface development by tubes or circles, forming part of the surface of the element using free mesh (loose) mesh instead of closed mesh mesh. The frame of the armchair and the sofa of Figures 1 and 2 is formed by the assembly of different nested elements constituting

  the backrest 1, the seat 2 and the sides 3 respectively.

  In particular, the elements constituting the sides 3, to which the function of feet is also entrusted, must have a high structural rigidity and, for this purpose, they have a box shape on all the sides and with sharp angles, presenting shaped circles in correspondence with edges and they are

  formed by an electro-welded mesh with very tight meshes.

  The element constituting seat 2 must have a

  considerable structural gidity and at the same time its superior surface

  higher must have high flexibility. For this purpose,

  side walls and the bottom surface are made of grill-

  tight welded wire, folded with a sharp edge, while the upper surface is formed by a tubular frame supporting

  a mesh with springs fixed to the side walls.

  The element constituting file 1, which must have a

  good surface flexibility as well as structural pre-

  feels a bearing surface 4 having a surface development

  considerable and made of electro-welded mesh with large mesh

  ges. In particular, the mesh of the mesh constituting the over-

  support face 4 have a rectangular shape, with the most

long placed vertically.

  In addition, the element constituting the backrest can have an open box configuration on the sides to allow

  for the element itself to deform plastically and to tilt

ner slightly back.

  The frame is covered with a layer of padding 5 made of spongy material having a differentiated density until

255515 2

  that the desired final shape and volume are obtained.

  The padding layer is fixed to the mesh frame and is covered with a fabric or equivalent material of a

know way and Cl] e-rmene.

  The elements forming the frame are fixed to each other by screws engaged in pairs of fixed coupling plates

to each element.

  With reference to FIGS. 5, 6 and 7, at least one pair of coupling plates 6 is fixed to a mesh of the mesh 7

  constituting the element, said plates 6 being opposite and as-

  seem to each other by means of a rivet 8 having a hole for

threaded axial passage 9.

  The surface of the plates 6 is equal to that defined by the sides 10, 11 of the mesh]] e mesh and each plate, in correspondence of two opposite sides, has grooves 12 projecting from the plate itself and suitable for house the round

  which constitutes the corresponding sides 10, 11 of the mesh.

  In each pair of opposing plates 6, the grooves 12 of one plate house the vertical sides 11 of the mesh of the mesh, while the grooves 12 of the other plate house

  the horizontal sides 10 of the same mesh of the mesh. Natural-

  Lement, in the case where the meshes of the mesh ort a square shape, the two plates 6 are equal and are offset by 90 between them. In the case where the meshes of the mesh have a rectangular shape, the two plates 6 are different and the grooves 12 of a plate protrude on its longest sides, while the grooves of the other plate are in

  protrusion on the shorter sides of the same plate.

  FIG. 7 illustrates two elements of a frame fixed to each other by a screw 13 engaged in two pairs of coupling plates 6. More particularly, at least one pair of plates 6 is fixed to each of the two elements which must be fixed between them. The plates 6 are fixed so that,

  when the elements are in the reciprocating position

  the threaded holes 9 of the rivets of the plates located opposite

  opposite are coaxial. A screw 13 is therefore engaged in the two

rivets 8.

  The coupling plates 6 can also be used.

  to fix accessories such as feet or

other.

  This method of tightening makes the frames of the furniture components modular and makes it possible to stuff and cover the elements constituting the frames themselves before they are

reciprocally coupled.

  As already said, the mesh constituting the elements of the frame can be of the tight mesh or wide mesh type; the dimensions of the mesh of the first type can have values between 2 x 2 cm and 6 x 6 cm and preferably are 4 x 4 cm; the dimensions of the mesh of the second type can assume values comprised between 2 x 4 cm

  and 6 x 12 cm and preferably are 4 x 8 cm.

  The diameter of the rounds constituting the mesh has

preferably a value of 2 mm.

  Ultimately, the present invention makes it possible to

  read, at costs lower than current cost prices, structures having at the same time high strength, high volume, good rigidity and flexibility characteristics

  chosen each time according to needs.

  The sofa and the armchair illustrated in the figures are only exemplary embodiments of the present invention which can be applied to achieve a very wide variety

  armchairs, couches, chairs, stools and furniture components

quite similarly padded.
