Definitions

  • the present invention concerns a mechanism for a so-called relaxation chair, in other words a chair which, as is known, is provided with a seat, a back and a footrest and which can be put from a sitting position into a reclined position.
  • the present invention concerns a mechanism for such a relaxation chair which can be put in the different positions in a continuous manner.
  • the seat is set in a fixed angle in relation to the supporting structure and the back and footrest are hinge-mounted to this seat, whereby a bar transmission forms an irregular parallel connection between the back and the footrest.
  • the known mechanisms are often difficult to operate.
  • the lever transmissions are selected such that they make it possible for an average person to tilt the chair in the required positions.
  • the length of the footrest is relatively short, since this length is limited by the distance between the seat to which it is linked and the floor upon which the chair is placed, one and other such that it is almost impossible for a normal person to let the feet rest on such a footrest.
  • the present invention aims a relaxation chair which systematically excludes the above-mentioned and other disadvantages of the known chairs.
  • a mechanism for a relaxation chair mainly consists of the combination of a seat which is provided on a support in a freely swinging manner via which the whole is fixed on a foot; hinge-mounted to this seat, on the one hand a back and on the other hand a footrest; bent bars which form a connection between the back and the footrest; transmission levers between the back and the above-mentioned support; compensating springs between the seat and the footrest; and flexible means provided between the seat and the footrest.
  • the footrest of the above-mentioned mechanism is extensible, to which end the footrest is formed of two parts which can be telescopically moved in relation to one another and whereby springs are provided between these parts which continuously try to move them apart.
  • the extension of the footrest will be limited first by the upholstery of the chair and/or by a foil of elastic material fixed to the mechanism.
  • Another special characteristic of the invention is the fact that the lever transmissions between the back and the support on which the seat is fixed in a swinging manner are determined such in combination with compensating springs provided between the seat and the footrest that the seat mechanism is almost always in balance in any position whatsoever.
  • the mechanism 1 mainly consists of a seat 2 which is fixed to a support 4 in a freely hinging manner which is fixed in turn to an actual foot support 5 which is for example designed such that such a chair can turn around pivot 6 of this foot support 5.
  • the back 8 To the rear end of the seat 2 is fixed, via a pivot 7, in a freely hinging manner, the back 8, whereas to the front end of the seat 2, via a pivot 9, in a freely hinging manner, is fixed the footrest 10.
  • the back support 8 is provided, at the height of its hinge point 7, with a forwardly directed protrusion 11 which so to say forms a lever and which, at its free end, is connected in a freely hinging manner, via a pivot 12, to the lever 13 which is connected in a freely hinging manner at its other end, via a pivot 14, to the support 4.
  • the back 8 is connected in a freely hinging manner tot the footrest 10 by means of bent bars 15 and pivots 16-17.
  • the footrest 10 consists of a first part 18 which is connected by means of draw springs 19 to the seat 2 and of a second part 20 which can be moved in a restricted manner in relation to the part 18, whereby this movement is controlled by springs 21 on the one hand, provided between the parts 18 and 20, and for example by the upholstery 22 of the chair on the other hand.
  • the chair mechanism When a person is seated in the chair in the position as represented in figure 1, the chair mechanism will be in balance thanks to the cooperation of the levers formed between the hinge points 12-13, 12-14 and 14-3 on the one hand, and the tensile force exerted by the draw springs 19 on the other hand.
  • the upholstery 22 makes sure, in this position, that the part 20 of the footrest 10, against the action of the springs 21, is maintained in the slid-in position.
  • FIG. 1 A preferred embodiment of a chair mechanism according to figures 1 to 3 is described in figures 4 to 10.
  • the seat 2 is formed as it were of two sides 24-25 which show outwardly directed parts 26-27 at the top which form the supports onto which the actual armrests can be fixed.
  • the sides 24-25 are connected to one another by means of a solid, bent tube 28.
  • Hingeable in 3 is provided a bent cross-plate 29 with the sides 24-25 which has a central attachment 30 with which this plate is connected to the above-mentioned foot 5, preferably in a rotatable manner.
  • the seat 8 is in this case formed of a U-shaped, tubular frame 31 in between which can be provided springy means which are not represented, whereby this frame 31 is connected in a removable manner at the bottom to a transversally directed plate 32 which has bent parts at its ends which form the above-mentioned protrusions 11 with which the levers 13 are fixed via pivots 12 itself.
  • At least one of the bent bars 15 shows a downwardly directed widening 33 in which is provided a bent groove 34, whereby a bar 35 passes through this groove which is screwed in a plate 36 which is fixed, for example by means of welding, to the side 24 or 25 concerned and whereby the free end of the bar 35 is provided with suitable press-on means which, when turned, draw the bar 15 against the plate 36, loosen it respectively, in order to lock the mechanism in a certain position, free it respectively, by changing the friction between the plate 36 and the bar 15.
  • the parts 18 and 20 of the footrest 10 are formed in this case of a square tube, save for the side parts 37 of the part 20 which are made as a U-profile, one and other such that guides 38-39 which are provided on the sides of the part 18 can be shifted in these side parts 37.
  • the springs 21 are provided around bars 40 which are fixed on the part 20, whereby these bars are provided with stops 41 at their free end which have as an aim to determine the maximum movement of the part 20 in relation to the part 18.
  • a foil (42) made of elastic synthetic material will also be provided onto such a mechanism, which can follow all the movements of the mechanism and which determines the final shape of the chair.
  • This foil will be fixed to the back 8 on the one hand and to the telescopic part 20 of the footrest 10 on the other hand.
