Description
The present invention relates to a buffer for a furniture hinge, and more particularly to a buffer for a furniture hinge, wherein a restoring spring for returning the press ring to its original position can provide restoring force outside the cylinder, So that the working distance of the rod can be extended.
Generally, the furniture is equipped with a sliding or hinged door. In particular, the hinged door is rotatably mounted using a hinge, and the hinge is equipped with a resilient return means such that the door can be easily closed. This is advantageous in that the door can be easily closed, but conversely, the door may be closed with a sudden rotation to cause noise.
Therefore, the hinge is equipped with a shock absorber (buffer) so as to prevent the doors from being suddenly closed and smoothly closed, thereby preventing noise from occurring and preventing door failures. Patent Documents 1 to 3 disclose a hinge having such damping means.
Patent Document 1 relates to a shock absorber, which comprises a damping housing, a fluid chamber disposed in the buffer housing and movably supported inside the piston, a fluid chamber connected to the piston and sealing the fluid chamber with the buffer housing, At least one seal for positioning the seal and a ram penetrating through the seal and a fluid-conducting relationship with the fluid chamber and extending laterally parallel to the fluid chamber, And a compensating chamber in which at least one variable compensating body for compensating for a change in volume caused by the ram entering the side of the compensating chamber is disposed.
Patent Document 3 proposes a decelerating hinge for a furniture door, particularly a furniture part having a face frame for fixing, having a decelerating device adapted to be associated with closing means positioned centrally in the hinge box have. It is also an object of the present invention to provide a hinge of the kind considered to be able to perform an effective deceleration action along a particularly wide swinging arc of the hinge. It is also an object of the present invention to provide a hinge of the kind considered, in which the decelerating device has a simple structure and can be easily assembled together.
These existing buffers are configured as follows. The normal buffer is provided in such a manner that the
Such existing furniture buffers have the following problems.
(1) Since the restoring spring is mounted in the cylinder, the length in which the actual buffer can be operated, that is, the working distance of the rod is shortened. This is because when the rod 3 is contracted as shown in Fig. 1 (a), since the
The conventional buffer mounts the
(3) The length of the buffer should be increased so that the end of the buffer mounted on the hinge (the end of the rod) can be brought into contact with the furniture door according to the shorter working distance of the rod (sum of W1 + W2).
(4) In order to obtain the same working distance, the length of the conventional buffer must be increased, which requires more manufacturing cost.
(5) In particular, when the furniture hinge is installed in a limited space as the length becomes longer, interference may occur with the hinge, the buffer, the buffer, and the door of the furniture.
(6) In order to compensate for the shortening of the working distance, the length of the rod and cylinder must be made longer or other components must be added to compensate for the increase in the number of components.
(7) As the number of components increases, a manufacturing cost is increased and there is a concern that a failure occurs, which makes maintenance difficult.
The present invention has been made in view of this point, and a restoring spring for restoring a press ring that acts as a piston can provide a restoring force from the outside of the cylinder, so that the structure can be easily manufactured, It is an object of the present invention to provide a buffer for a furniture hinge which can secure a working distance of the load as much as the space occupied when compressed, thereby increasing the effective working distance of the buffer.
Further, in the present invention, an auxiliary flow path is provided between the press ring and the rod, in addition to the main flow path between the press ring and the inner surface of the cylinder, so that the press ring can stably move and the rod can naturally and smoothly expand and contract Another object is to provide a buffer for a furniture hinge that can be made durable with noise prevention.
Further, according to the present invention, the working distance of the rod can be varied by moving the rod chamber and the rod chamber base, which airtight between the cylinder and the rod, in the longitudinal direction of the cylinder, thereby further improving the effect of preventing leakage of the working fluid. The buffer for the furniture hinge which makes it possible to easily construct the entire structure so that it can be easily maintained without failures but can increase the working distance of the load as much as possible There is another purpose in providing.
According to an aspect of the present invention, there is provided a furniture hinge buffer comprising: a press ring having a container shape and being expanded and contracted according to a pressure therein; A
The
Lastly, the
The buffer for a furniture hinge according to the present invention has the following effects.
(1) Since the restoring spring provides the restoring force of the rod outside the cylinder, it can extend the working length by the length of the restoring spring when compressed in the cylinder.
(2) In addition, since the construction of the sponge for generating airtightness and frictional force can be omitted, the structure can be simplified and the number of parts can be reduced, which can be expected to reduce manufacturing cost.
(3) In particular, since the working length of the rod can be increased by the length of the compression spring of the restoring spring and the configuration of the sponge, the working length can be extended by about 40% compared with the conventional buffer When the distance is 17 cm, the present invention is a working distance of about 30 cm).
(4) Since the rod chamber and the rod chamber base, which prevent leakage between the rod and the cylinder, are configured to be movable in the rod longitudinal direction, the working space can be expanded and contracted, So that the working length of the rod can be further extended.
(5) When the buffer is mounted on the hinge with the extension of the operating length as described above, the buffering effect can be maximized by increasing the length of the buffering action even when the door of the furniture is opened and closed. Even if the weight of the door is heavy or the closing speed is fast, Since the operation length of the door is long, it is possible not only to increase the buffering effect but also to prevent the noise or breakage caused by the door not touching the rod, so that the effect of increasing the quality can also be expected.
