Definitions

  • the present invention relates to an armrest, in particular for office chairs.
  • Armrests consisting of a substantially L-shaped support bracket, with the end of the horizontal arm connected to the support structure of the chair seating portion and with the upper end of the vertical arm connected to a pad on which the user's arm rests.
  • CN 2011 948 441 U describes an armrest provided with a pushbutton 90 having one end engaged in the lateral surface of the sleeve and the other end provided with an appendix selectively engagable with one of the teeth of a rack provided in an L-shaped bracket.
  • a coil spring 84 maintains the end of the pushbutton 90 engaged in the rack and returns it to this configuration when pressed to adjust the tube height.
  • An object of the invention is to eliminate all these drawbacks by providing an armrest which can be assembled rapidly without the use of tools.
  • the armrest according to the invention is made of plastic material and comprises an L-shaped bracket 2 with its vertical part 4 of rectangular cross-section and its horizontal part 6 engagable in the support structure of the seating portion.
  • a plurality of horizontal parallel slots 10 are provided in a lateral wall 8 of the vertical part 4 of the bracket 2 and are connected together by a continuous vertical slot 12.
  • Said surface is also provided with two slits 14 which define two flexible tabs 16.
  • the vertical part 4 of the bracket 2 is slidably inserted into a corresponding tubular sleeve 18, the upper end of which is rigid with a pad 20.
  • a substantially square aperture 30 is provided in the sleeve surface.
  • the invention also comprises a lever-shaped push-element 32 which presents at one end a reduced-thickness step 34 insertable into the seat 28, an intermediate rib 36 which rests on the surface of the cavity 26 to form a fulcrum for the push-element, and at its other end 38 is inclined oppositely to the intermediate rib 36 and bent at 90° into two T-shaped appendices 40.
  • the heads 42 and the shank 44 of the appendices 40 are of a size and shape suitable for insertion into two horizontal adjacent slots 10 and into as vertical slot 12, respectively, of the wall 6 of the bracket 2.
  • the procedure is as follows: after inserting the reduced-thickness step 34 into the seat 28 and inserting the end 38 into the aperture 30, the push-element 32 is pushed right down so that it rotates on the intermediate appendix 36, and the upper part of the bracket 2 is inserted into the bottom of the sleeve 18.
  • the shank 44 deflects the two tabs 16 to then engage in the slot 12.
