Definitions

  • the present invention relates to an opening and closing mechanism for a door of furniture for example.
  • the invention relates to a mechanism for closing a door, which comprises a biasing mechanism for closing the door automatically, quietly by restraining a sudden motion in a direction of closure when the door is nearly totally closed.
  • the entrance doors of houses are provided with door closure mechanisms for automatically closing the door.
  • Such closure mechanisms contain a spring and a damper and close the door through a link.
  • Such door closure mechanisms are relatively large and are not suitable for use in the opening and closing of furniture doors.
  • the damper generates a low force of resistance in a wide angular range with respect to the door and as a result the problem has arisen that the opening and closing time of the door is lengthened.
  • the present invention is proposed to solve the above problems.
  • the present invention comprises an opening and closing mechanism for a rotating door which opens and closes an open section of furniture used for storage (hereafter storage furniture).
  • the opening and closing mechanism supports a rotational center of the door with respect to a frame of the storage furniture and is provided with a sprung hinge which biases in a direction of door closure and a damping device which comes into contact with the inner surface of the door when the door is almost closed and applies a damping force, the damping device is mounted on a section of the frame.
  • the damping device is buried in the inner framework and a push rod of the damping device bumps with the inner surface of the door from a perpendicular direction.
  • the present invention enables the damping device to apply a damping force immediately prior to total closure of the rotating door.
  • quiet closure of the door is enabled and the generation of noise and vibration are prevented.
  • a force of resistance is only applied immediately prior to total door closure, the overall time for the total opening and closing of the door is not lengthened.
  • the opening and closing mechanism has a small size, has no effect on the aesthetic appeal of the storage furniture and does not reduce the storage capacity of the storage furniture.
  • Fig. 1 is a perspective view showing a first embodiment of the present invention.
  • Fig. 2 is a cross sectional view of the inner components of the present invention.
  • a rotating door 2 mounted on an opening section of storage furniture 1 is supported at upper and lower points on one side of the door 2 on a frame 4 by a hinge 3 provided with a spring which are known in the art.
  • a hinge 3 provided with a spring which are known in the art.
  • only one door 2 is shown of the pair of right and left doors 2.
  • the sprung hinge 3 is provided with a spring in an inner section and biases the door 2 in a direction of closure with the force of the spring. Thus the door 2 when open is closed automatically by the force of the spring.
  • a damping device 5 is mounted on a section of the end face 4A of the frame 4 at a position oriented towards the leading edge of rotation of the upper side of the door 2.
  • the mounting position of the damping device 5 is preferably a position in which contact is achieved with the door 2 in a range from at least the center of the door 2 which rotates about the sprung hinge 3 to the leading edge of rotation.
  • the damping device 5 is fixed and stored in the mounting hole 6 provided on the end face 4A in the frame 4, as shown by the imaginary line, and when the door is open the push rod 7 of the damping device 5 projects from the end face 4A of the frame 4.
  • the push rod 7 is pressed in a projecting direction by a spring (not shown) provided in the inner section of the damping device.
  • a piston (not shown) in the inner section of the damping device 5 is displaced. The displacement of the piston is limited by the resistance of a fluid in the damping device 5 and thus a rapid closure of the door 2 is prevented.
  • the force of resistance of the damping device 5 is set to be smaller than the pressing force of the sprung hinge 3 in the direction of closure of the door 2.
  • the shape of the damping device 5 is cylindrical and thus it is possible to dispose the damping device 5 simply in the mounting hole 6 by forming a hole circular in cross section by a drilling operation or the like.
  • a hole is not formed and the damping device 5 may be mounted by the provision of a bracket or similar member on the lower surface of the frame 4. It is also possible to dispose the damping device 5 in the frame 4 on the lower side of the door so as to come into contact with the lower edge of the door 2.
  • the opening and closing mechanism for a door 2 according to the present invention is smaller than a conventional door closing mechanism and in particular when the damping device 5 is buried in the frame 4, the design of the furniture is not adversely affected and the storage capacity of the furniture is not reduced.
