Definitions

  • the subject of the present invention is an improved chair according to the preamble to the main claim.
  • the backrest and the seat are completely separate from one another and have respective engagement means and complementary engagement means for subsequently joining them together.
  • the main object of the present invention is to provide a chair which is improved in comparison with the prior art.
  • Another object of the invention is to provide a chair in which the backrest and the seat are joined together, even during the transportation stage.
  • a further object of the invention is to render the conversion of the chair from the transportation condition to the condition of use reversible.
  • a chair according to the present invention including a moulded body 1 made of rigid or semi-rigid plastics material, is generally indicated P.
  • the body 1 comprises a lower part 2, preferably formed as a unitary piece by injection moulding and including a seat 3, a pair of arms 4a, 4b, and a lower portion 5 of a backrest, generally indicated 8.
  • the backrest 8 also comprises an upper portion 6 which is articulated to the lower part 2 about an axis X, in the region of the ends 7 of the arms 4a, 4b which are closest to the lower portion 5.
  • a cylindrical seating 10 elongate along the axis X and having a through-window 11 in its wall, is formed in each arm.
  • Each seating 10 is open at both of its axially opposed ends.
  • the upper portion 6 of the backrest has, in the region of its base 13, a rib 14 which can stiffen the base 13 and can constitute means for coupling with the free upper end 15 of the lower backrest portion 5.
  • the upper backrest portion 6 is flanked on its two opposite sides by two, approximately parallel, coextensive flanges 18 each bearing, at its lower end, a tubular, cylindrical appendage 19.
  • Each cylindrical appendage 19 has a pair of parallel and spaced-apart slits 20, between which there is a wall portion 20a bearing a projection 21 at its free end. Owing to the presence of the slits 20, the wall portion 20a is flexible radially so as to allow the appendage 19 to be inserted in the corresponding seating 10 of the respective adjacent arm. The appendage 19 is then restrained in the corresponding seating by snap-engagement of the projection 21 in the window 11.
  • the projection 21 is positioned angularly relative to the backrest and to the window 11 in the seating 10 in a mariner such that, when the upper backrest portion 6 is folded parallel to the seat 3 (the lowered position of Figure 4b), the projection 21 is in contact with the continuous inside wall of the seating 10 and keeps the appendage 19 in a radially retracted state.
  • the positioning of the projection 21 is also such that, when the upper backrest portion 6 is set upright, perpendicular to the seat 3, in the operative position of Figure 4a, the projection 21 is engaged in the window 11, preventing further pivoting of the upper backrest portion 6 about the axis X.
  • the projection 21 is not subjected to stresses when the user leans on the backrest since, in this condition, the base 13 of the upper backrest portion 6 is in abutment with the upper end 15 of the lower backrest portion 5, defining a mechanical travel-limit stop for the relative pivoting between the upper backrest portion 6 and the lower backrest portion 5.
  • a plug 25 provided with a flange 26 having a diameter substantially corresponding to the inside diameter of the seating 10 and a cylindrical portion 27 having a diameter substantially corresponding to the inside diameter of the appendage 19 in the state in which it is not retracted radially is also provided for insertion in the appendage 19 in order to keep the latter in the radially extended state which corresponds to the engagement of the projection 21 in the window 11.
  • further radial retraction of the wall portion 20a and of the projection 21 is prevented, the projection 21 being restrained in the window 11 so that the upper backrest portion 6 is prevented from rotating relative to the lower backrest portion 5 and to the arms.
  • the appendage 19 comprises a window 31 which is intended to constitute a seat for a projection 34 formed at a free end of an element 35 projecting axially as an extension of the cylindrical portion 27 of the plug 25.
  • the window 31 is generally L"-shaped and includes a first region 32 for axial sliding of the projection 34 and a second region for circumferential sliding thereof.
  • the plug 25 also has an outer cylindrical portion 36 coaxial with and radially spaced from the cylindrical portion 27, having an outside diameter substantially equal to the inside diameter of the seating 10, and extending axially for a distance equal to the difference between the axial dimension of the seating 10 and that of the appendage 19.
  • the outer cylindrical portion 36 comprises a catch projection 37 which can engage for sliding axially in a guide 38 formed in the seating 10, thus preventing relative rotation of the plug 25 once it is inserted in the seating 10 of the respective arm.
  • the rotation of the backrest portion 6 about the axis X which enables the chair P to be brought to the operative position brings about circumferential sliding of the projection 34 along the region 33 of the window 31.
  • the window 31 and the projection 21 are positioned relative to one another on the appendage 19 in a manner such that the projection 21 snap-engages the window 11 at the moment at which the projection 34 of the plug 25 reaches the region 32 of the window 31.
  • the plug 25 can thus be inserted fully in the seating 10, since the projection 34 can slide axially in the region 32 until the free end of the outer cylindrical portion 36 abuts the free end of the appendage 19, or the projection 34 abuts the edge of the region 32 of the window 31.
  • part of the cylindrical portion 27 abuts the wall portion 20a, locking it in its radially expanded condition.
  • the invention thus achieves its objects, overcoming the limitations complained of with reference to the prior art cited.
