Definitions

  • the invention refers to a device to be applied to an armchair with a view to allowing its rotation around a vertical axis while at the same time, if necessary, rocking similar to the movements of a rocking chair. (rocker).
  • the state of the art comprises numerous devices which permit both rotation of an armchair around the axis normal to the seated plane and its rocking so as to function as a rocking chair.
  • Such devices have a significant importance in the production and sale of leather armchairs, or those in fabric or other suitable material, since easier to apply and to use. (rendering application and use easier).
  • the above mentioned devices are generally furnished with a fifth wheel which permits rotation of the armchair around a vertical axis and with a mechanism placed between the fifth wheel and the same armchair which permits rocking around the axis normal to that of rotation.
  • a medium or large armchair having a significant weight, requires a solid and robust/resistant device which permits rotation or rocking while at the same time, due to its simplicity, may be realised using material lighter in weight than steel-like materials and therefore requiring minimum maintenance.
  • the angular rocking movements of the above mentioned supporting elements are actioned by two helicoidal springs , below the fifth wheel, on a transversal axis fixed to the horizontal axis around which rock the said supporting elements.
  • the aim of the present invention is to eliminate the above mentioned drawbacks.
  • the device solves the problem of a greater adaptability of the armchair to the weight of the individual wanting to cause rocking without application of springs requiring significant elastic deformation.
  • the invention also solves the problem of reducing friction among the parts constituting the device and the noise of the fifth wheel during its rotation by means of the application of an anti-friction disc realised in teflon or other suitable material in place of the ball bearings.
  • Another problem solved is the possibility of building a device of reduced dimension.
  • the device rocking and rotating on a filth wheel, is applied to a base 9 of the armchair realised in wood or in other suitable materials (figures 3, 5, 6).
  • the device as illustrated in figure 2, is made up of a fixed lower plate 1 upon which is positioned an anti-friction disc 2, preferably circular in shape, and upon this a second rotating upper plate 3 is placed acting as a fifth wheel which rotates around a rotation pin 4 which, with the interposition of a washer 4.2 at the extremity, is blocked (into position) by a split-pin 4.1 or nut if threaded.
  • the fixed lower plate 1 of the fifth wheel is laterally shaped so as to form two "C-shaped" profiles 1.4, furnished with holes 1.2 in order to permit insertion of bolts 1.3 so as to fix the armchair P to the base 9 (figure 3).
  • the upper rotating plate 3 is also laterally shaped so as to form two counter-positioned "C-shaped" borders 3.3 upon each of which a springy curved flat bar 5 , like that of the base of a rocking chair, is mounted by means of screw bolts 5.3 which, at the same time connects a metallic bracket 6 'V' shaped with the aim of limiting the range of the rocking movements with its extremely 6.2. (figure 5).
  • the springy curved flat bars 5 are then fixed to a plate 7 furnished with two bended borders 7.1 and holes 7.2 for their blocking by means of screws 5.4.
  • Transversal metal bars 8 are fixed to the plate 7 by means of welds 13, and the metallic bottom 10 is connected to said metal bars by means of bolts 12 screwed into particular threaded holes 8.1.
  • the connection between the metallic bottom 10 of the armchair and the transversal metal bars 8 is achieved by means four wings 11 welded to the metal bottom 10 and bolts 12: i.e. the metal bottom 10 screwed to the wood base base of the armchair by bolts 10.1.
  • the device may be furnished with elastic attachments 6.3 positioned in corrispondence to the bolts 5.3 that block the brackets 6 (figure 7).
  • the metallic bottom 10 of the armchair may rotate in respect to the support base 9 of the same armchair.
