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 when these pieces of furniture collide 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.
  • This type of sheath pressed against the structural element, remains totally dependent on the specific configuration of this structural element and only reduces the disadvantages of the effects of idio- to a very small extent, if not at all. phone mentioned above.
  • DE-A-1 554 454 describes a seat generally produced from a tubular profile and in which armrests are made of elastic or semi-rigid material. These armrests, however, have large cavities which can resonate during certain impacts. In addition, the plastic covering is limited to the area of the armrests so that no anti-noise effect is obtained during a side impact on the seat.
  • An object of the invention is to propose a structure of furniture with anti-noise characteristics making it possible to obviate these drawbacks, by proposing a structure consisting of the assembly of a structural element and a sheathing element, arranged around of this structural element offering, without modification of costs and without reduction in mechanical strength, remarkable sound absorption against the effects of idiophone 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 proper structure of the structural elements, tractors or carriers, providing the supporting framework for a piece of furniture.
  • a furniture structure with anti-noise assembly comprising at least a first structural element of elongated shape and a second sheathing element substantially of the same length as the first element and surrounding this last, characterized in that the second element is made of a rigid or at least semi-rigid material and in that the first element comprises a series of longitudinal edges between which space is formed between the first and second elements. the profile circumscribed at the edges being equal to or slightly less than the internal profile of the second element in order to produce a clearance forming a cushioning cushion over the major part of the periphery of the first element between the latter and the internal profile of the second element.
  • FIG 1 a ladder type furniture structure that can also constitute part of the base of a chair, and comprising a bar 1 connecting two uprights 2 and 3.
  • the right upright 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 core 6.
  • the circle circumscribing the ribs or ridges 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, fitted on the first element 6.
  • the bar 1 is housed at its ends in stepped recesses in 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 to receive the end of the sheath 9, the sheath 5 of the upright of course having a cut similar 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 to receive the end of the sheath 9, the sheath 5 of the upright of course having a cut similar to the shallower bore 11.
  • the same type of mounting is adopted on the left upright 3 of FIG.
  • the amount 3 may also include a core 4 'fully 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 can have a polygonal section, inscribable in the circle of the diameter internal 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 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 spacings 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.
