Definitions

  • the present invention relates generally to chairs and armchairs with an oscillating seat, and more particularly to a central stand for supporting and adjusting the inclination of the seat in said chairs and armchairs.
  • the seat means formed of seat and back is usually oscillatingly assembled on a central immovable support.
  • Said central stand is applied to the top of a base or post, in case adjustable in height, and besides supporting the oscillating seat, it is provided with a plurality of parallele sheets interacting with a stopping-releasing pivot which passes through them to adjust and stabilize as one wishes the seat inclination by means of a hand lever.
  • the stand and the parallele sheets are made of independent and originally separated elements.
  • the stand is composed of a body or block and the sheets are then joined to said body or block by welding or by means of pivots, pins or like.
  • Another object of the invention is to provide a central stand for oscillating seats made of one element only, advantageously realizable in plastic material and not requiring welding work or junction by welding or with pivots, pins or like.
  • the central stand is composed of a block 10 and a plurality of parallel sheets 11 integrally joined to block 10, the whole in plastic material.
  • Block 10 has a tapered hole 12, where in case a bush 13 may be inserted, and a transverse hole 14 in a right-angled plant to the tapered hole.
  • the sheets 11 have, in a transverse direction, an arched slot 15 concentric to the transverse hole 14.
  • a seat-carrying oscillating plate 16 is mounted, in the rear part of which a stand 18 for a back is hinged at 17. More precisely, the described central stand is mounted on a base or supporting post 19, in case adjustable for height, whose top is tapered and inserted in the tapered hole 12 of the block 10 - see Fig.3.
  • the seat-carrying plate 16 is applied to the block 10 by means of a pivot 20, inserted in the transverse hole 14 of the block and constitutinng the oscillating axe of the seat.
  • a stopping-releasing device 21 actuated by a hand lever 21a is mounted on the seat-carrying plate 16 for locking/unlocking the sheets 11.
  • Such device which is already known in the art, has a pivot or tie rod 22 which extends in the arched slot 15 of the sheets 11 and is engaged to the plate 16.
  • a second block 24 is hinged, at 23, to said back support 18, and also provided with a plurality of sheets 25 integral with it. Said sheets 25 are directed and inserted in the spaces among the sheets 11 of the central stand and have an oblong slot 26 where the pivot or tie rod 22 of the stopping-releasing device 20 extends.
  • the central stand consisting of block 10 integral with the sheets 11, always remains fixed and immovable on the base or supporting post 19, while the seat-carrying plate 16 can oscillate on said central stand and the back relatively to the seat-carrying plate.
  • said oscillations are possible when the device 20 set in action by the lever 21 is in the releasing position so as to let the sheets 11, 21 free.
  • the central stand which is always provided with integral sheets 11', could have am oblong-shaped block 10' as shown inn the Fig.4 of the drawing, in order to apply also a springy device 27 contrasting the seat oscillations.
