Definitions

  • the present invention relates to a hinge and, more particularly, to a hinge having a damping device capable of different damping actions.
  • German utility model DE 20 2012 003 508 U1 discloses a furniture hinge mechanism with a damping device for damping a pivoting movement of a movable furniture part and with adjusting means for an adjustment of the damping operation.
  • US Patent No. 8,689,402 B2 discloses a furniture hinge comprising at least one control cam and at least one spring, wherein the control cam moves along on the spring in order to produce a closing force and/or opening force, wherein a sliding element is attached to the spring and/or to the control cam.
  • the control cam or the spring moves along on the sliding element.
  • the damping hinge assembly includes a housing (10), an arm (12), at least one spring (14), a maintaining member (16), a damper (18), and an adjustment member (20).
  • the arm (12) is pivotally connected to the housing (10).
  • the housing (10) includes a chamber (36).
  • the spring (14) is mounted in the chamber (36) of the housing (10) and serves to provide a resilient closing force when the housing (10) is pivoted with respect to the arm (12) and is thereby being closed with respect thereto.
  • the maintaining member (16) is fixedly mounted in the chamber (36) of the housing (10) and has a path (72) for receiving the damper (18).
  • the damper (18) is mounted in the path (72) of the maintaining member (16) and corresponds to the arm (12).
  • the damper (18) has a piston rod (76).
  • the adjustment member (20) is movably mounted to the maintaining member (16) and has a protruded portion (92) to correspond to the piston rod (76) of the damper (18).

  • the adjustment member (20) has been displaced with respect to the maintaining member (16) to a second position instead, the protruded portion (92) of the adjustment member (20) will not correspond in position to the piston rod (76) of the damper (18), and if the housing (10) is subsequently closed with respect to the arm (12), the piston rod (76) of the damper (18) will not be pressed against the protruded portion (92) of the adjustment member (20) and hence will not produce any damping effect.
  • the piston rod (76) of the damping device can produce a damping effect when the adjustment member (20) has been displaced with respect to the maintaining member (16) to the first position, but if the adjustment member (20) has been displaced with respect to the maintaining member (16) to the second position, the piston rod (76) of the damping device cannot be pressed against the protruded portion of the adjustment member to produce the damping effect.
