Definitions

  • the object of this invention is an armchair with arms having one end hinged to the front legs by means of devices with adjustable suspension and the opposite end carrying the adjustable-setting back.
  • a further object of this invention is to provide an armchair or the like equipped with arms and back with variable tilting and adjustable in a continuous manner so as to impart conditions of maximum comfort in any position.
  • such coil springs include free ends respectively attached to appropriate inserts in the arms and front legs and maintained transversally in position by means of shaped bodies which in turn have transverse inserts for attachment to appropriate locating pins.
  • Such shaped bodies have furthermore, respectively, a further through insert and an insert with a female thread respectively for the passage and engagement of a screw capable of adjusting the clamping of the bodies by increasing or reducing the friction of suspension of the arms with respect to the legs.
  • such hinged means for the swivelling of the back in relation to the arms are preferably comprised of a pair of bushes respectively made integral with the arms and with the flanks of the back and capable of rotating in relation to one another around a pin consisting of a screw passing through such bushes and capable of engaging the internal thread of a coaxial member, provided with an external thread for the stable link with the back.
  • means for limiting the rotation of the back preferably consisting of a washer, provided with a cavity the end walls of which are capable of entering into contact with a pin integral with the bushes to determine the length of angular travel of the back.
  • the armchair according to the invention comprises a supporting frame 1 formed by legs 1a and support 1b of seat 1c.
  • Upper end-part 2a of front legs 1a has a connection zone 2b which determines an angle "A" of inclination toward the front part of such end 1a, which has a free end-segment 2c of substantially square section within which are provided two inserts 2d of substantially circular section extending into such end-part 2a substantially throughout its length and forming an angle "B" with the vertical axis of front leg 1a.
  • Such inserts 2d are capable of accommodating lower ends 3a of a pair of coil springs 3 located around an orthogonal axis relative to that of inclined end 2a of leg 1a and the other ends 3b of which are capable of being attached to appropriate inserts 4b like those 2d of legs 1a and provided axially in arms 4 of the said armchair.
  • Such arms are therefore connected in a substantially hinged manner to legs 1a, the stable link between them being provided by means of two shaped lateral bodies 5 provided with appropriate transverse inserts 5a capable of accommodating locating and holding pins 6 which are capable of allowing perfect coupling and linking of the articulation between the front legs and the arms.
  • Such lateral bodies 5 also have further inserts 5b and 5c respectively, the first of which is a through insert and the second is provided with thread 5d for the insertion and operation of suitable means of adjustment of the friction and of the return action of the spring capable of increasing or reducing the hardness of the articulation and therefore of increasing or reducing the degree of suspension of the arm relative to the leg.
  • such means of adjustment are represented by an adjusting screw 7 which, on engaging female thread 5d determines the increase or reduction of compression of shaped bodies 5 and therefore of springs 3.
  • arms 4 are made integral with back 8 via a device 9 substantially of hinged type consisting of a bush 9a of substantially tubular shape, at one end of which is provided a flange 9b which is secured, by means of screws 10a within the lateral thickness of back 8, coaxially to a member 11 with external thread and internal thread also inserted in the flank of the back; the hinge joining the arm and the back is completed on the part of the arm by a second bush 12 of substantially "H" form drilled transversally to allow the passage of a screw 13 which, on passing also through bush 9a, engages the internal thread of threaded member 11 to operate the holding link between arm 4 and back 8 which is, however, free to rotate around its own transverse axis in order allow the change of orientation thereof upon varying from the inclination of the support of the user and/or from the position of the arms.
  • a device 9 substantially of hinged type consisting of a bush 9a of substantially tubular shape, at one end of which is provided a flange 9b which is secured, by
  • the arms and back can assume different positions of use either independently of one another or in relation to one another, ensuring also a suspension action thereof for the greater comfort of the user.
  • means for adjusting the length of angular travel of the back substantially consisting of a cavity 15, provided in washer 14c, the end walls of which are capable of engaging a pin 16 integral with flange 9b of bush 9a.
  • means for adjusting the relative friction consisting for example of packing made of friction material the greater or lesser action of which determines an increase or reduction of the degree of hardness of rotation.
  • the armchair according to the invention also has a floor-support end on leg 1a equipped with a spherical member 1b pressing on the floor by the action of a spring 15 capable of supporting the weight of the armchair and of becoming compressed under the pressure resulting from the load exerted by the user when seated; in this way the armchair may be easily moved when not in use but is stably supported on the rectangular section of leg 1a when the user is seated.
  • the armchair according to the invention also has means for cushioning the impact of the front surfaces of the arms and front legs, preferably consisting of a rubber ring (18) located around the upper end of leg (1a), such ring also being capable of preventing the accidental insertion of foreign matter between such surfaces.
