Abstract
Description
- The present invention relates to an opening and closing mechanism for a door of furniture for example. In particular, 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.
- Conventionally furniture doors or the like are biased in a direction of closure by a hinge provided with a spring. When the door closes, a large sound and vibration are produced by contact with the frame particularly if the door is released when about to close.
- However when the hinge spring has a weak adjustment, door closure is inconvenient and the door is sometimes not suitably retained at a closed position.
- In contrast to furniture doors, 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. Furthermore 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. Thus quiet closure of the door is enabled and the generation of noise and vibration are prevented. Since 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. Furthermore 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.
- The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.
- In Fig. 1, a rotating
door 2 mounted on an opening section of storage furniture 1 is supported at upper and lower points on one side of thedoor 2 on a frame 4 by ahinge 3 provided with a spring which are known in the art. In the drawings, only onedoor 2 is shown of the pair of right andleft doors 2. - The
sprung hinge 3 is provided with a spring in an inner section and biases thedoor 2 in a direction of closure with the force of the spring. Thus thedoor 2 when open is closed automatically by the force of the spring. - As shown in Fig. 2, when the
door 2 is closed, thedoor 2 is disposed in close contact with theend face 4A of the frame 4 of the storage furniture 1. Adamping device 5 is mounted on a section of theend face 4A of the frame 4 at a position oriented towards the leading edge of rotation of the upper side of thedoor 2. - The mounting position of the
damping device 5 is preferably a position in which contact is achieved with thedoor 2 in a range from at least the center of thedoor 2 which rotates about thesprung hinge 3 to the leading edge of rotation. - The
damping device 5 is fixed and stored in themounting hole 6 provided on theend face 4A in the frame 4, as shown by the imaginary line, and when the door is open thepush rod 7 of thedamping device 5 projects from theend face 4A of the frame 4. Thepush rod 7 is pressed in a projecting direction by a spring (not shown) provided in the inner section of the damping device. When depressed by contact in a perpendicular direction by theinner surface 4A of thedoor 2, a piston (not shown) in the inner section of thedamping device 5 is displaced. The displacement of the piston is limited by the resistance of a fluid in thedamping device 5 and thus a rapid closure of thedoor 2 is prevented. - However it is noted that the force of resistance of the
damping device 5 is set to be smaller than the pressing force of thesprung hinge 3 in the direction of closure of thedoor 2. - The shape of the
damping device 5 is cylindrical and thus it is possible to dispose thedamping device 5 simply in themounting hole 6 by forming a hole circular in cross section by a drilling operation or the like. When the thickness of the frame 4 is lower or equal to the radius of thedamping device 5, a hole is not formed and thedamping 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 thedamping device 5 in the frame 4 on the lower side of the door so as to come into contact with the lower edge of thedoor 2. - In such a way, when the
door 2 is automatically closed by thesprung hinge 3, immediately prior to the complete closure of thedoor 2, thepush rod 7 of thedamping device 5 come into contact orthogonally with the inner surface of thedoor 2 and applies a brake to the motion of thedoor 2. Thus as the door is closed slowly, noise or vibration generated when thedoor 2 is closed rapidly are greatly reduced. - Since the damping operation with respect to the
door 2 is limited to immediately prior to total door closure, no resistance is applied to thedoor 2 in other operational ranges and thus the opening and closing speed of thedoor 2 is not reduced. - It is possible to freely regulate the angle of the
door 2 at which damping is initiated by varying the mounting position of thedamping device 5 with respect to the rotational radius of thedoor 2. Furthermore the number of sprunghinges 3 or dampingdevices 5 may be optimally varied in response to the size or weight of the door. - 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 thedamping 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. - The present invention is not limited to the above embodiments and variations will occur to those skilled in the art within the scope of the inventive concepts which are stated in the following claims.
