[0001] The present invention relates to a chair or the like with facilitated assembly.
[0002] It is known that chairs designed for various uses, such as for example office furniture,
currently comprise several components which are assembled directly in the factory
or at the installation site by specialized operators or even by the user.
[0003] The components that constitute chairs usually provide for interlocking couplings
and, particularly for accessory components, couplings provided by threaded elements
or equivalent connections.
[0004] Currently, even chairs having a rather simple structure obtained by means of a small
number of components require time to be assembled.
[0005] It is in fact well-known that the operations for assembly performed by using threaded
elements are troublesome and time-consuming.
[0006] Applying a threaded element in awkward positions, may in fact entail a significant
degree of difficulty and in any case always entails a certain waste of time even for
skilled users.
[0007] A chair according to the preamble of claim 1 is disclosed in document US-A-3 054
643.
[0008] The aim of the present invention is to provide a chair or the like whose structure
comprises components connected without using threaded elements or similar types of
coupling.
[0009] Within the scope of this aim, an important object of the present invention is to
provide chairs or the like whose structure is particularly solid and functional and
allows highly ergonomic use.
[0010] Another object of the present invention is to provide chairs or the like whose structure
is particularly flexible and can be manufactured in different shapes and configurations,
having also a high aesthetic and styling value.
[0011] Another object of the present invention is to provide a chair or the like with a
structure that is easy and quick to assemble even for personnel lacking specific experience.
[0012] Another object of the present invention is to provide a chair or the like with a
structure that can be manufactured at competitive costs, despite resorting to conventional
equipment, with respect to chairs or the like having a similar functionality.
[0013] This aim, these objects and others which will become apparent hereinafter are achieved
by a chair or the like with facilitated assembly, comprising components which are
adapted to form at least one seat and at least one back which are applied exclusively
with interlocking couplings, said back comprising at least one rigid support which
is fixed, by means of first engagement elements, to posts protruding from said frame,
a body which supports a layer of padding being applied by interlocking coupling on
said rigid support, said seat comprising a rigid base which is fixed by interlocking
coupling to a flat supporting element, these last being in turn fixed by interlocking
coupling, by second engagement elements, to at least two horizontal cross-members
of said frame.
[0014] Further characteristics and advantages of the present invention will become apparent
from the description of an embodiment thereof, illustrated only by way of non-limitative
example in the accompanying drawings, wherein:
Figure 1 is a perspective view of a chair having the structure according to the invention;
Figure 2 is a partially exploded perspective view of the chair of Figure 1;
Figure 3 is an exploded view of a detail of the chair of Figure 1;
Figures 4 and 5 are sectional orthographic projection views of a corresponding number
of details of the chair of Figure 1;
Figure 6 is a sectional orthographic projection view of another detail of the chair
of Figure 1;
Figure 7 is a partially exploded perspective view of the chair of Figure 1;
Figure 8 is a perspective view of a detail of the chair of Figure 1;
Figure 9 is a perspective exploded view of another detail of the chair of Figure 1.
[0015] With reference to the above Figures, a chair with facilitated assembly having the
structure according to the invention is generally designated by the reference numeral
10 and comprises components which are applied exclusively by interlocking coupling
to a frame 11 and are adapted to form a seat, generally designated by the reference
numeral 12, and a back, generally designated by the reference numeral 13.
[0016] The back 13 comprises a contoured rigid support 14 which is applied by means of respective
first engagement elements, described in greater detail hereinafter, to two posts 15
protruding from the frame 11.
[0017] In particular, said first engagement elements, in this embodiment, are constituted
by two guides 21 which are formed on the rigid support 14, each guide comprising the
combination of two mutually opposite series of tabs 20 so as to form a receptacle
for the corresponding end portion of a corresponding post 15.
[0018] A layer of padding 16 is applied by interlocking coupling to the rigid support 14
and is supported by a body 16a, as described in detail hereinafter.
[0019] Pins 22 cantilever out from the rigid support 14 of the back 13; each pin is provided
with a mushroom-shaped head 23 on which there are notches 24 which ensure the appropriate
elastic flexing.
[0020] Each one of said pins 22 is adapted to be inserted by interlocking coupling in a
corresponding tubular seat 25 formed in the body 16a that supports the layer of padding
16.
[0021] Moreover, in this embodiment, two pins 26 protrude from said body 16a; the position
of each one of said pins corresponds to a hole 27 formed in the rigid support 14 at
each one of the corresponding guides 21.
[0022] Correspondingly, a hole 28 is formed in each final portion of the posts 15.
[0023] In this manner, once the two portions of post 15 have been inserted in the respective
guides 21, the fixing of the layer of padding 16 to the rigid support 14 allows to
simultaneously fix it to the frame 11, since the two pins 26 pass through the corresponding
holes 27 and 28 formed respectively in the rigid support 14 and in the posts 15.
[0024] The seat 12 of the chair 10 comprises a contoured rigid base 17 which is designed
to support a layer of padding, which is not shown for the sake of simplicity.
[0025] Said rigid base 17 is fixed by interlocking coupling to a flat supporting element
18 and, at the same time, to two cross-members 19 of the frame 11.
[0026] In this embodiment, said flat supporting element 18 has four openings 29 which are
adapted to be crossed by second engagement elements protruding monolithically from
said rigid base 17.
[0027] Said second engagement elements comprise clamp-like elements 30 which are made of
a flexible material and protrude from the rigid base 17 on the side designed to be
fixed, by interlocking coupling, to the flat element 18 and to the cross-members 19.
[0028] Each one of said clamp-like elements 30 is in fact adapted to pass through a corresponding
opening 29 formed in the flat element 18 in order to anchor, by interlocking coupling,
to a corresponding cross-member 19.
[0029] In this embodiment, connecting pins 22 cantilever out from the flat supporting element
18; said pins are fully similar to those described earlier for the back 13 and are
adapted to be inserted, by interlocking coupling, in corresponding tubular seats 25
formed in the rigid base 17 on the side directed toward the flat element 18.
[0030] In practice it has been observed that the present invention has achieved the intended
aim and objects.
[0031] It should in fact be noted that the chair or the like executed according to the present
invention allows rapid, safe and precise assembly.
[0032] All the components that constitute the chair according to the present invention can
in fact be connected by means of a guided and very simple assembly which does not
require particular tools.
[0033] Attention is also drawn to the possibility to assemble the chair in a highly simplified
manner with respect to conventional chairs, eliminating the costs of threaded studs
and screws and the cost for their assembly.
[0034] Another advantage is that the ease of assembly achieved by means of interlocking
couplings in no way damages the overall safety and structural solidity of the chair
according to the present invention.
[0035] Attention is also drawn to the fact that the constructive simplicity allows to provide
chairs and the like at costs which are competitive with respect to currently commercially
available chairs and the like having a similar functionality.
[0036] The present invention is susceptible of numerous modifications and variations, all
of which are within the scope of the inventive concept as defined by the claims.
[0037] The materials used, so long as they are compatible with the contingent use, as well
as the dimensions, may be any according to requirements.
[0038] The disclosures in Italian Patent Application No. PD99A000072 from which this application
claims priority are incorporated herein by reference.
[0039] 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 interpretation of each element identified by way of example by such reference
signs.
