[0001] The present invention relates to a flexible cushion particularly for armchairs, couches
and pieces of furniture in general.
[0002] As is known, cushions for armchairs, couches and pieces of furniture in general are
often manufactured by using blocks of foamed material which are shaped so as to give
the cushion the intended shape.
[0003] This embodiment gives the advantage of obtaining relatively stable shapes for the
cushion, following the intended profiles, but on the other hand an elastic response
is obtained which does not allow to achieve a springiness, for the cushion, comparable
with old-style cushions obtained by means of a padding with mutually tied springs.
[0004] In an attempt to improve springiness characteristics, other known solutions use an
internal body constituted by flexible blocks formed by arranging side by side several
metal wire springs individually placed inside bags, which allow to obtain a region
of springiness with conventional springs; the springy block is then covered with a
layer of cotton wool, feather, wool or the like to produce the desired continuity
on the outer surface.
[0005] Although this kind of solution has better springiness characteristics than cushions
entirely made of foamed plastic material, it has the drawback that it does not allow
to precisely obtain the intended profiles, since unavoidably the outer covering layer
of cotton wool, feather and the like produces rounded areas at the corners and in
any case does not allow to produce profiles of particular shapes.
[0006] An aim of the present invention is to solve the above described problem by providing
a flexible cushion which allows to have the easy shaping possibilities of cushions
made of foamed plastic material although it has the springiness characteristics typical
of cushions provided with internal springs.
[0007] Another object of the invention is to provide a flexible cushion which can be shaped
as desired according to the preferred profile without thereby encountering production
problems.
[0008] Another object of the present invention is to provide a flexible cushion which, by
virtue of its particular constructive characteristics, gives the greatest assurances
of reliability and safety in use.
[0009] Another object of the present invention is to provide a flexible cushion that can
be easily obtained starting from commonly commercially available elements and materials
and is furthermore competitive from a merely economical point of view.
[0010] With this and other objects in view, there is provided, according to the present
invention, a flexible cushion particularly for armchairs, couches and pieces of furniture
in general, characterized in that it comprises a substantially flat-shaped body made
of flexible foamed plastic material, said body defining an internal cavity which accommodates
an elastic block constituted by a plurality of metal wire springs arranged side by
side.
[0011] Further characteristics and advantages of the present invention will become apparent
from the following detailed description thereof, illustrated only by way of non-limitative
example in the accompanying drawings, wherein:
figure 1 is a schematic exploded view of the cushion according to the invention;
figure 2 is a perspective view of a possible embodiment of the cushion;
figure 3 is a partially cutout view of the cushion, showing the layers that form it;
figure 4 is a sectional view, taken along the plane IV-IV of figure 2.
[0012] With reference to the above figures, the flexible cushion particularly for armchairs,
couches and pieces of furniture in general, according to the invention, comprises
a substantially flat body l which is made of flexible foamed plastic material.
[0013] Advantageously, said body 1 has elements that are mutually joined by glueing or the
like and are constituted for example by a bottom layer 2 on which perimetrically arranged
lateral blocks 3 are applied; said blocks form an internal cavity 10 which is closed
by an upper layer 4.
[0014] Optionally, there is also an upper shaping layer designated by the reference numeral
11.
[0015] An important feature of the invention is an elastic block, generally designated by
the reference numeral 20, which is provided inside the cavity 10; said block comprises
multiple metal wire springs 21 which are advantageously barrel-shaped and individually
inserted in bags, so as to form rows of springs arranged mutually adjacent and forming
a compact set of side-by-side springs.
[0016] The metal wire springs accordingly form, inside a body made of foamed material, an
excellent springing element, allowing to obtain any appropriate external profile by
virtue of the possibility to shape the foamed-material body as desired.
[0017] Advantageously, there is also an external covering 30 which is optionally provided
with a layer of cotton wool or the like 31 that produces a softness and surface continuity
that make the cushion particularly appreciable.
[0018] Of course it is also possible to provide a cover meeting the aesthetic characteristics
deemed appropriate.
[0019] From the above description it is thus evident that the invention achieves the intended
aim and objects, and in particular the fact is stressed that the provision of a cushion
made of foamed plastic material and internally provided with an elastic block constituted
by multiple metal wire springs arranged side by side allows to combine the typical
easy shaping advantages of foamed-material cushions with the springiness characteristics
obtainable only with metal wire springs.
[0020] In practice, although the best results have been obtained with the above mentioned
materials, the materials employed and the contingent shapes and dimensions may be
any according to the requirements.
[0021] Where technical features mentioned in any claim are followed by reference signs,
those reference signs have been included for the sole purpose of increasing the intelligibility
of the claims and accordingly such reference signs do not have any limiting effect
on the scope of each element identified by way of example by such reference signs.
