Definitions

  • the present invention relates to a chair or the like with facilitated assembly.
  • 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.
  • the components that constitute chairs usually provide for interlocking couplings and, particularly for accessory components, couplings provided by threaded elements or equivalent connections.
  • a chair according to the preamble of claim 1 is disclosed in document US-A-3 054 643.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • said first engagement elements 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a hole 28 is formed in each final portion of the posts 15.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the materials used may be any according to requirements.
