Definitions

  • the present invention relates to a bearing structure for a chair, a desk chair, a stool or similar.
  • the said item of furniture shall be indicated in the current description, by the single term "chair”.
  • the object of the invention is .also a chair comprising the said bearing structure.
  • chairs and similar items of various types .and with v.arious cl racteristics have been used and marketed for a long time and, in their simplest form, are comprised of a seat supported by a structure which, in general, is comprised of four legs.
  • a structure which, in general, is comprised of four legs.
  • chairs which have a different number of legs for technical, aesthetic or other reasons.
  • it is particularly useful to manufacture chairs which can be stacked one on top of the other.
  • Chairs of this kind generally have sloped legs, for example, those formed with a pair of inverted V-shaped legs.
  • the possibility of stacking different chairs one on top of the other is particularly advantageous feature if the chair is to be used in bars or restaurants or even in homes, and in any case, any time it is necessary to collect them up in a limited space.
  • the chairs being part of the commonly known technique, are fitted with wheels to facilitate the movement of a person when seated.
  • a frequently used embodiment involves the creation of a single central leg from which a certain number of feet, generally five, branch out. The said feet have wheels connected to their ends in such a way that they can rotate.
  • the applicant of this present application has identified the need to introduce a chair which combines the characteristics of stackability and mobility on wheels into the market.
  • the aim of this present invention is, therefore, to produce bearing structures for chairs which can be mobile because of the presence of wheels and, at the same time, can be stacked one on top of the other.
  • a further aim of the invention is to produce a bearing structure which is both simple and cheap to manufacture.
  • Another aim of the invention is to produce a bearing structure fitted with wheels which are commonly available on the market, to make them still more easily and quickly available.
  • a further aim of this invention is to produce a bearing structure which is safe and reliable.
  • a bearing structure for a chair, desk chair, stool or similar comprising a frame body to which the closest ends of a plurality of elongated legs are attached, said legs being characterised by the fact that there is a wheel mounted to each furthest end of the elongated legs, said furthest ends being separated one from the other by a distance greater than that between the closest ends to allow the bearing structures to be stacked one on top of the other.
  • figure 1 is a perspective view of a bearing structure according to the invention
  • figure 2 is a perspective view of the bearing structure of figure 1 which is supporting a chair comprised of a seat and back-piece.
  • the bearing structure has four elongated legs 2, connected to a frame body 10.
  • the legs are, preferably but not exclusively, produced using a single tubular piece for the pair of front legs and a single tubular piece for the pair of back legs.
  • Attached to the frame body 10 are the seat structure 3 and, in particular, the piece comprised of the seat 4 and the back-piece 5 of a chair.
  • Each leg has a closest end 7 attached to the frame body 10 and a furthest end 9 which a respective wheel 6 is connected to.
  • the wheels 6, of a type commonly available on the market, are connected to the legs by a pivot pin 12 inserted into a housing on the furthest end 9 of each leg; the pins 12 allow the wheels 6 to rotate around an axis which is perpendicular to the supporting surface, in this way facilitating the mobility of the chair.
  • the form of the legs 2 is designed to allow the chairs to be stacked one on top of the other.
  • the distance between the furthest ends 9 is greater than the distance between the closest ends 7.
  • the furthest ends 9 of the legs are produced practically parallel with each other and in particular perpendicular to the supporting surface to allow pins 12 of the wheels to be inserted easily into the housings on the legs.
  • Each leg 2 has a middle section 8 placed between the furthest end 9 and the closest end 7 which is sloping in relation to both of the said ends and converges towards the frame body 10.
  • the closest end 7 and the sloping middle section 8 coincide.
  • the frame body 10 is preferably, but not exclusively, comprised of initial transversal elements 13, each one, for example, forming an integral part with a pair of legs, .and second longitudinal elements 14 integral with the transversal elements 13.
  • the longitudinal elements 14 are connected in a permanent way, for example welded, to the transversal elements 13.
  • a different type of connection is possible, in p.articul.ar a dismountable one, which can be made using bolts or similar elements of a commonly known technique.
  • the folded areas 11, which mark out the various zones comprised of the single legs 2 are rounded for aesthetic, technical and safety reasons.
  • the structure according to the invention proved to be particularly advantageous for the production of a swivel chair.
  • the said structure was also decidedly convenient in use since it is fitted with wheels and, at the same time, can be stacked on top of other chairs of the same type.
  • the said structure is therefore suited to all uses in which, if the said chair is not needed, it can be placed with others where it is not possible or it is undesirable for it to take up space.
  • the materials used, as well as the dimensions can be suited to fit the needs and the technology.

Abstract

Structure de support conçue pour une chaise, un fauteuil de bureau, un tabouret ou un article similaire et comprenant une armature (10) à laquelle sont fixées les extrémités (7) les plus proches d'une pluralité de pieds allongés, chacune des extrémités (9) les plus lointaines possédant une roulette correspondante (6) et étant séparée des autres extrémités (9) les plus lointaines d'une distance supérieure à la distance reliant les extrémités (7) les plus proches, ce qui permet d'empiler plusieurs structures de support les unes au-dessus des autres.
