Definitions

  • the present invention relates to chairs or armchairs with a seat and / or a backrest provided with a support device with variable position, and more particularly a system for mounting a tilting lever intended to control the device which regulates the position of the chair or armchair.
  • the seat is fixed on a plate applied to the top of a stretchable upright fixed to the support base and normally consisting of a gas spring or other equivalent spring device.
  • the object of the invention is therefore to solve these problems and to eliminate the drawbacks and disadvantages of the embodiments proposed up to now.
  • the invention provides easy and quick mounting of the pivoting lever on the support plate without the aid of special tools and without any complicated operation.
  • the tilting lever is simply introduced into a transverse hole drilled in a rotating cylinder which serves as a rotating pin, previously mounted on the support plate of the chair.
  • the tilting lever on one side and the transverse hole of the pin on the other side have complementary sections for coupling without the lever being able to rotate in the aforementioned hole, while being able to tilt with the pin around its axis.
  • the assembly between the pin and the rocking lever is ensured, in the axial direction, by a part of the adjoining plate to the transverse hole of the pin and intended to intercept at least one projection of the lever to prevent the output and uncoupling of the pin.
  • the mounting system which forms the object of the invention is therefore characterized in that the seat support plate is provided with a T-slot, that on this plate, near the above-mentioned T-slot, an element cylindrical functioning as a pin and having a transverse hole with at least one transverse hole with at least one radial recess, and in that the rocking lever has at least one lateral projection corresponding to the radial recess of the cylindrical element, the lever being conjugated, by threading, with the transverse hole of the cylindrical element through the widest part of the T-slot, the sides of the narrow part of the T-slot intercepting the lateral projection to prevent uncoupling of the lever.
  • Fig. 1 of the drawing the number 10 indicates the base of a chair or armchair on which the upright 11 is fixed, for example in the form of a gas spring or other equivalent device and extendable in height, its top carrying a plate support 12 for the seat 13 and also for the backrest 14, the extension of the upright 11 being controlled, in a known manner, by a lever 15.
  • the rocking lever 15 is mounted on the plate 12 by means of a cylindrical element 16 having the function of a pin. More specifically, the plate 12 has, in an appropriate position, a T-slot, vis-à-vis which and inside the plate 12 pivots the cylindrical element 16. The latter has, to be, when it is mounted, in correspondence with the T-slot of the plate 12, a transverse hole 18 with a radial recess 19 , The cylindrical element 16 is stopped on the plate 12 by means of a jumper 22, the eyelet 21 of which is in correspondence with the hole 18 of the cylindrical element 16.
  • the tilting lever 15 has a section similar to that of the transverse hole 18 of the cylindrical element 16 and it is provided with at least one lateral projection 22 intended to be combined with the radial hollow of the above-mentioned hole 18.
  • the T-slot 17 of the plate 12 comprises a narrow part having a width slightly greater than the section of the lever 15 and a wider part to allow the passage of the lever 15 with its lateral projection (s) 22 .
  • the lever 15 can be threaded, through the slot 17, into the hole 18 of the cylindrical element 16, until one of its lateral projections 22 is inserted into the radial recess 19 of the hole 18 and in such a way that the end of the lever mates with the device 11 to be controlled.
  • the lever 15 and the cylindrical element 16 are coupled and can be moved angularly around the axis of the pin.
  • the lever can be moved in the narrow part of the T-slot 17, the sides of which will intercept the lateral projection (s) 22 to prevent the lever from moving and therefore the disassembly of the lever, even allowing the operating movements of the lever itself. even.
