Definitions

  • This invention relates to a device to be applied to the seat of a chair, the seat being capable of turning over.
  • the rotation of the seat to move from an essentially vertical position, with a closed chair, to a horizontal position, with an open chair, and viceversa, which is carried out by the spectator himself may be free or may be bound by mechanisms which have the tendency of keeping the seat in the vertical position.
  • the object of the present invention is to provide a device for regulating in a chair the motion of the seat which is capable of turning over, which device is particularly simple from both the constructive as well as the functional point of view. and further a device which does not require upkeep and which allows the seat, when it is raised, to come as close as possible to the back of the chair, so as to reduce to a minimum the clutter of the closed chair.
  • This object is achieved according to the invention by means of a boxed body which is anchored to the supporting bar of the aligned chairs and which contains in the interior at least one group of articulated lever devices, this body being bound at one extremity to the body itself and at the other extremity to the base of the seat capable of turning over.
  • Every group of the articulate lever devices is constituted by two levers which are reciprocally placed side-by-side and fitted together, at one extremity in a idle manner on two pins which are integral with the boxed body.
  • An elastic element provides for carrying out a force opposite to the action of lowering of the seat, and operates in the direction of moving towards locating the seat in an essentially vertical manner.
  • Figs. 1 and 2 show device (1) of the invention with the seat capable of turning over (2) and the back(3). The device is blocked by means of plug (4) to the transversal bar (5) which supports a row of chairs.
  • Figs. 3-6 show the device (1) constituted by boxed body (6) in the interior of which are placed two groups of articulated lever devices (7) which are disposed symmetrical to spiral spring (8).
  • Each group of the articulated lever devices (7) comprises two levers, (9) and (10) which are parallel and hinged at one extremity in an idlel manner on two fixed pins (11) and (12) which are blocked on the boxed body.
  • the other extremity of the two levers (9) and (10) is hinged on one of the two pins (13) and (14) which function also for double unknotting of the stirrup (15), the latter supporting seat (2).
  • the four pins (11), (12), (13), (14), which have parallel axes, are disposed in such a manner that when seat (2) is completely raised as shown in Figs. 3 and 4, one of the two levers of each group, preferably lever (9) which is more external, becomes hooked with its groove (16) on one of the two unknotting pins (13).
