Definitions

  • the present invention refers to a chair with folding seat, so that when the user stands up from the chair, the seat returns automatically to its substantially vertical original position.
  • the chairs with folding seat known up to now comprise automatic returning means of the seat to its substantially vertical position.
  • These means habitually are formed by a counterweight, so that when the user stands up from the chair, and thanks to the counterweight action, the seat returns to its substantially vertical position.
  • this counterweight causes the hinge axis of the seat to be displaced forwardly, so that there is a clearance between the back and the seat when the seat is in its substantially vertical position.
  • these damping means are formed by a spring whose compression is adjusted by means of a screw. According to the compression degree, the damping of this movement is carried out in greater or smaller extent.
  • Another type of damping devices of the seat returning movement comprises a cylinder of pressurised gas.
  • these devices present the drawback that they are expensive and they require maintenance.
  • the chair with folding seat comprises a back and an seat hinged to the back about a hinge axis, said seat being moveable between a substantially vertical position and a substantially horizontal position, and it also comprises automatic returning means of the seat from its substantially horizontal position to its substantially vertical position when the user stands up from the seat; and it is characterized in that these automatic returning means of the seat to its substantially vertical position are arranged on the hinge axis, the hinge axis being located in the contact area between the back and the seat.
  • these automatic returning means of the seat to its substantially vertical position comprise elastic means integral with the seat that cause the turn of the seat from its substantially horizontal position to its substantially vertical position about the hinge axis, which is integral with the back.
  • these automatic returning means of the seat to its substantially vertical position also comprise, preferably, a sleeve, arranged around the hinge axis, integral with the seat and that rotates about the hinge axis.
  • these elastic means are formed by an helical spring, whose compression can be regulated by means of a screw.
  • the chair of the present invention also comprises damping means of the turning movement of the seat between its substantially horizontal position and its substantially vertical position, avoiding, therefore, that the seat hits the back.
  • this damping means are formed by a carcass, which houses inside it a piston provided with a hole communicated with an air chamber defined between the carcass and the piston; and by an fin integral with the seat, which contacts the upper part of the piston when the seat turns from its substantially horizontal position to its substantially vertical position, moving the piston down as the air comes out through the hole.
  • damping means used in the chair of the present invention have a reduced cost and they need no maintenance practically.
  • this carcass comprises an helical spring disposed around the carcass, being linked the helical spring with the piston housed inside the carcass, so that the down movement of the piston is carried out against the action of the elastic means and pressing the air inside the air chamber.
  • the chair according to the invention comprises a sealing gasket disposed between the carcass and the piston.
  • this fin extends across the whole seat, two carcasses being provided with their corresponding pistons at each end of this fin.
  • fig. 1 is a perspective view of three chairs according to the invention placed one beside the other one, two of them with the seat in its substantially vertical position, and the third chair with the seat in its substantially horizontal position;
  • the chair according to the invention comprises a back 1 and a folding seat 2, which can be in a substantially vertical position, in the case of the first two chairs, or in a substantially horizontal position, like in the third chair shown.
  • the chair according to the invention comprises automatic returning means of the seat to its substantially vertical position when the chair user stands up from the seat. These means are seen in detail in fig. 2.
  • the hinge axis 6 is integral with the back 1 of the chair, it presents in its central part a sleeve 7 integral with the seat 2, and the sleeve 7 rotates about the hinge axis 6.
  • the hinge axis 6 comprises a helical spring 8 disposed around it, an end 9 of this helical spring 8 being integral with the seat 2.
  • the helical spring 8 comprise a screw 10 that allows to regulate the tension of the spring 8, pressing in greater or smaller extent this screw 10.
  • the tension of the spring 8 will be regulated so that the seat 2 returns to its substantially vertical position in a slight way without hitting the back.
  • the hinge axis 6 is disposed in the contact area between the back 1 and the seat 2, since it is not necessary a counterweight, the helical spring 8 carrying out the function of the counterweight in the chairs known up to now. Therefore, thanks to the arrangement of the hinge axis 6, when the seat 2 is in its substantially vertical position, it does not exist practically any separation between the back 1 and the seat 2, avoiding the accumulation of dirt and dust in the area that will be in contact with the user's body.
  • the damping means of the movement of the seat from its substantially horizontal position to its substantially vertical position comprise a couple of air cylinders 11 and a fin 12 integral with the seat 2.
  • the function of the air cylinders 11 and of the fin 12 may be seen more clearly in fig. 5.
  • the cylinder 11 is formed by a cylindrical carcass 13 in whose interior moves a piston 14, defining between the carcass 13 and the piston 14 an air chamber 15, Between the piston 14 and the carcass 13 it is arranged a sealing gasket 16 to avoid an air loss between the piston 14 and the internal wall of the carcass 13.
  • a helical spring 18 whose function is to maintain the piston 14 in its upper position.
  • the piston 14 comprises a hole 17 in its lower part in communication with the air chamber 15.
  • the dimensions of this hole 17 will be the appropriate to allow the exit of an appropriate volume of air to carry out the damping action, as it will be explained hereinafter in detail.
  • the spring 8 rotates the seat 2 from its substantially horizontal position to its substantially vertical position.
  • the fin 12 will contact with the upper part of the piston 14, which will be in its upper position.
  • the piston 14 will damp the turning movement of the seat 2, avoiding the seat 2 to hit the back 1.
