Definitions

  • the present invention relates to pieces of furniture and more particularly, a structure of furniture with anti-noise assembly.
  • Modern pieces of furniture for example chairs, stepladders or ladders have, whatever the material of the elements of these pieces of furniture, very pronounced idiophone effects during the collision of these pieces of furniture between them or with fixed structures, as we can see when installing performance halls or banquets, and especially in schools, more particularly in kindergartens.
  • modern pieces of furniture are frequently made with elements at least partially covered with a coating, obtained either by depositing a lacquering material or by placing a heat shrinkable plastic sheath.
  • a coating obtained either by depositing a lacquering material or by placing a heat shrinkable plastic sheath.
  • This kind of sheath, pressed against the structural element remains totally dependent on the specific configuration of this structural element and only reduces to a very small extent, if at all, the drawbacks of the aforementioned idiophone effects .
  • the object of the present invention is precisely a furniture structure with anti-noise characteristics allowing to overcome these drawbacks, by proposing a structure consisting of the assembly of a structural element and a sheathing element, arranged around this structural element offering, without modifying costs and without reduction in mechanical strength, remarkable sound absorption against the effects of idio p hone and a significant reduction in the weight of the structure.
  • Another object of the present invention is a furniture structure of this type offering great flexibility of use by making, in particular, the external appearance of the furniture structure, conferred by the sheathing elements, relatively independent of the structure proper structural elements, tractors or carriers, providing the supporting framework for a piece of furniture.
  • the structural and sheathing elements are shaped and positioned relative to each other so that a space forming a cushioning cushion is provided on most of the interface between the elements.
  • the elements have in cross section relative sections such that in the assembled position, a clearance is provided over the major part of the periphery of the structural element between the latter and the internal profile of the second element.
  • the structural element advantageously of wood, is grooved longitudinally over its entire length, the profile exinscribed to the ribs delimiting the grooves corresponding in value less than the internal profile of the sheathing element, advantageously made of plastic material, for example colored.
  • FIG. 1 a ladder-type furniture structure which can also constitute part of the base of a chair, and comprising a bar 1 connecting two uprights 2 and 3.
  • the upright on the right 2 is of the known type with a smooth core 4, coated with a plastic sheath 5, for example, heat shrinkable.
  • the bar 1 also shown in FIG. 2, comprises a first structural element where core 6, of cylindrical shape, advantageously of wood and formed, on its periphery, with grooves 7, obtained for example by jaws during of the conformation of the bar 6.
  • the circle exinscribed to the ribs 8 projecting between the grooves 7 corresponds in value slightly less than the internal diameter of the rigid or semi-rigid sheath 9, made for example of acrylonitrile-butadiene-styrene or high-density polyethylene density, fitted on the first element 6.
  • the bar 1 is housed at its ends in stepped recesses of the uprights 2 and 3, these stepped recesses comprising a deeper central bore 10, to receive the end of the core 6, and a shallower coaxial bore 11 for receiving the end of the sheath 9, the sheath 5 of the upright of course having a cutout analogous to the shallower bore 11.
  • stepped recesses comprising a deeper central bore 10, to receive the end of the core 6, and a shallower coaxial bore 11 for receiving the end of the sheath 9, the sheath 5 of the upright of course having a cutout analogous to the shallower bore 11.
  • the same type of mounting is adopted on the left upright 3 of FIG.
  • the upright 3 can also include a core 4 'entirely grooved in the manner of the bar 1, the end cap 13 then being produced simply in the form of a protective cap.
  • the core 4 ′ has a homothetic section of the cylindrical sheath 5 ′ but, as shown in FIG. 3, the core 40 may have a polygonal section, inscribable in the circle of the internal diameter of the sheath 12, so as to bear, thus being centered against the latter only by the edges 15 of the polygon, by providing between its edges air cushions 16, occupying more than 95% of the interface between the structural element and its sheath.
  • the core 41 produced for example in the form of a tube or a profile metallic, has a diameter or, more generally, an outer profile of dimensions considerably smaller than the inner profile of the sheath 120, cylindrical or prismatic.
  • the relative positioning of the two elements 41 and 120 is obtained by connecting means 42, 43 transversely connecting the two elements, extending across the large space 44 phonic isolating the core 41 from the sheath 120.
  • the connection means are produced by radial fins 42, projecting towards the inside the sheath 120, to form a bearing surface 45 for the core 41, the furniture structure shown in FIG. 4 being closed at the end by a simple cap 130.
  • the connecting means have been made by spacers 43, for example of plastic material or hard rubber, fitted on the core 41, the sheath 120 being in turn fitted on these spacers 43.
  • spacers 43 for example of plastic material or hard rubber
  • the relative positioning of the core 41 and the sheath 120 can be ensured at the end by a cap 13 ′ having concentric recesses for receiving the ends of the sheath and of the core.
  • the embodiment with a ribbed core shown in Figures 1 and 2 also has a significant advantage with regard to the connection between the bar 1 and the uprights 2 and 3 insofar as the grooves 7 allow a backflow and good distribution of the adhesive disposed in the bottom of the bore 10 prior to the fitting of the bar into the upright.
  • the present invention has been described in relation to particular embodiments, it is not limited thereto but is on the contrary subject to modifications and variants which will appear to those skilled in the art.
  • the es pitches or clearances between the core and the sheath can be, at least locally, filled with a divided or multicellular stuffing material increasing the sound absorption qualities and also the mechanical strength of the piece of furniture.
