Definitions

  • the invention relates to a piece of furniture with a stationary support, in particular a furniture body, a pivoting element that can be moved relative to the stationary support, in particular a moveable furniture part, and with at least one fitting of the type to be described.
  • a furniture hinge is shown, a hinge arm to be fastened to the furniture body and a hinge cup to be fastened to the movable furniture part being pivotably connected to one another via two articulated levers.
  • the furniture hinge is held in a closed end position by a spring device in the form of a coiled torsion spring.
  • the torsion spring is formed from a spring wire with a rectangular cross section. In this way, a greater spring force can be stored in the torsion spring—in direct comparison with a spring wire with a round cross section and the same spring length.
  • the torsion spring is supported on the one hand on one of the both articulated levers and on the other hand on an underside of the hinge arm.
  • the object of the present invention is to specify a fitting of the type mentioned at the outset while avoiding the above disadvantages, with the aim in particular of improving the friction conditions of the fitting.
  • the at least one support element for supporting the spring device is rotatably mounted, preferably on at least one articulated lever.
  • At least one rotatably mounted support element is provided for supporting a leg of the spring device, so that there is rolling friction between the surfaces of the spring device and the support element that abut one another.
  • a rolling frictional force is usually significantly lower than a sliding frictional force. In this way, the wear on the fitting and the forces required to move the fitting can be reduced and the service life of the fitting can be increased.
  • the at least one supporting element in a rotatable manner on the first fitting part, on the second fitting part and/or on the at least one articulated lever of the fitting.
  • the fitting has an inner articulated lever and an outer articulated lever, with the at least one support element being rotatably arranged on the inner articulated lever.
  • the piece of furniture according to the invention has a stationary support, in particular a furniture body, a pivoting element that can be moved relative to the stationary support, in particular a movable furniture part, and at least one fitting of the type in question, the first fitting part of the fitting being on the stationary support and the second Fitting part of the fitting is attached to the swivel element.

  • the fitting 4 can have at least one damper 9 (not visible here), by means of which a relative movement of the two fitting parts 5, 6 to one another can be damped.
  • a closing movement and/or an opening movement of the pivoting element 3 up to the fully closed end position and/or fully open end position in relation to the stationary carrier 2 can be damped by the damper 9 .
  • Figure 2a shows the fitting 4 in the form of a hinge 4a for the movable mounting of the pivoting element 3 relative to the stationary support 2.
  • the fitting 4 comprises a first fitting part 5 for attachment to the stationary support 2 and a second fitting part 6 for attachment to the pivoting element 3, the two fitting parts 5, 6 are pivotally connected to one another via at least one articulated lever 7a, preferably at least two articulated levers 7a and 7b.
  • the first fitting part 5 has a hinge arm and/or that the second fitting part 6 has a hinge cup.
  • the fitting 4 can have at least one damper 9, by means of which a relative movement of the two fitting parts 5, 6 to one another can be damped.
  • the at least one damper 9 can, for example, comprise at least one piston-cylinder unit with a preferably cylindrical damper housing 10, with a piston rod 12 of the damper 9 being mounted displaceably relative to the damper housing 10.
  • the second fitting part 6 has a hole 14, the piston rod 12 of the damper 9 being guided through the hole 14 in an assembled state.
  • the damper 9 can be arranged via at least one fastening point 13 on an outer side of the second fitting part 6 .
  • the damper 9 In an assembled state, the damper 9 is arranged below a fastening flange 15 of the second fitting part 6 , the second fitting part 6 together with the damper 9 being able to be arranged in regions within a single cylindrical bore of the pivoting element 3 .
  • FIG Figure 2b shows the fitting 4 in the form of the hinge 4a according to FIG Figure 2a with the damper 9 in an assembled state.
  • Figure 3a shows the fitting 4 in the form of the hinge 4a in an open position.
