However, in the case of the sliding door type, there is a disadvantage in that it is necessary to secure a certain turning radius that can be opened and closed by the width of the door. Are applied to furniture.

In the case of the sliding door, a rail is provided at the upper and lower portions of the storage space of the furniture, and a roller corresponding to each rail is rotatably fixed to the upper and lower portions of the door through a fixing bracket, This sliding door is referred to as a sliding door.

However, due to the load and gravity of the sliding door, as the use time passes, the connecting portion between the fixing bracket and the sliding door widens and gradually sinks downward. When the sliding door sinks downward, The sliding doors do not form a flat surface and are shifted, which is not good for aesthetic appearance, and a smooth sliding operation can not be performed.

Meanwhile, when the sliding door for furniture is closed, the rollers come into rolling contact with the rails due to the moving force, and the sliding contact with the ends of the rails causes a large noise, and damage to the opening and closing devices such as rollers, fixing brackets, and rails may occur , The sliding door is repelled by the moving force of the sliding door in the direction opposite to the moving direction and is not completely closed.

In this case, the space required to form the shock absorber must be extended from the end of the rail, so that there is a spatial constraint. Therefore, such a structure is applied When the moving force of the sliding door exceeds the buffering capacity of the shock absorber, noise is generated and the sliding door can not stop at the end portion and is thrown out in a direction opposite to the moving direction, so that the sliding door can be opened and closed accurately The disadvantages that can not be achieved still remain.

The first roller 103 is slid along the first rail 21, So that the sliding door 10 can be opened and closed.

The auxiliary roller structure 120 is rotatably connected to the first fixing bracket 101 so that an end of the auxiliary roller structure 120 opposite to the connection portion with the first fixing bracket 101 is connected to the connecting bar And an auxiliary roller 122 rotatably fixed to an end portion of the connecting bar 121 opposite to the first fixing bracket connecting portion so that the auxiliary roller 122 is fitted to the first rail 21 to be in rolling contact therewith, (10) and at the same time, the sliding door (10) is pulled toward the opposite side in the striking direction.

The first roller bracket 102 includes a shaft 102a connected to the first fixing bracket 101 and a shaft 102a of the first roller bracket 102, A first elastic member 104 such as a spring is interposed between the horizontal position of the first roller 103 and the horizontal position of the auxiliary roller 122 when the slope of the auxiliary roller 122 changes with the rotation of the connecting bar 121 And is configured to be stretched to fit.

The second roller structure 200 is located at a middle portion of the sliding door 10 with respect to the closing of the sliding door 10 and includes the second rail 22, the second roller structure 200, A buffer means 300 is provided.

The second rail 22 is provided on the upper surface of the furniture 20 in parallel to the first rail 21 and its end portion is positioned only up to the middle portion of the first rail 21 and rounded at a constant curvature.

The second roller structure 200 includes a second roller bracket 202 fixed to an intermediate portion of an upper end portion of the sliding door 10 through a second fixing bracket 201 to be rotatable in a planar manner, And a second roller 203 fixed to the second roller bracket 202 so as to be brought into rolling contact with the second roller 203. The second roller 203 is slid along the second rail 22 to open and close the sliding door 10 As shown in FIG.

The buffering means 300 contacts the shaft 202a of the second roller bracket 202 when opening and closing the sliding door 10 to buffer the moving force of the sliding door 10 and at the same time the second roller bracket 202 A buffering operation tool 301 which is rotated while being in contact with the shaft 202a of the second roller bracket 202 and a stopper 309 which limits the rotation range of the buffering operation tool 301 302), and a second elastic member (303) for providing an elastic force to the buffer operation member (301).

The buffering operation tool 301 has a rounded guide groove 304 for guiding the tip of the buffering operation tool 301 in contact with the shaft 202a of the second roller bracket 202. The opposite end of the buffering operation tool 301 is formed on the upper surface of the furniture 20 And is rotatably fixed.

At this time, when the buffering operation tool 301 is moved in the direction in which the sliding door 10 is closed at the position where the buffering operation tool 301 is caught by the stopper 302, the shaft 202a of the second roller bracket 202 is hooked, 10 is moved in the direction from the closed state to the open state, the position where the buffer operation member 301 is caught by the stopper 302 is set to the reference (reference) position so that the shaft 202a of the second roller bracket 202 can move smoothly The sliding door opening direction side of the guide groove 304 is formed only to a position not interfering with the shaft 202a of the second roller bracket 202 while the sliding door closing direction side of the guide groove 304 is formed in the second roller bracket 202, And the shaft 202a of the first motor 202a.

The stopper 302 is a structure for restricting the rotation range of the shock absorber 301 when the sliding door 10 is opened and is provided on the sliding door opening side of the shock absorber 301.

The second elastic member 303 is a structure that is connected between the middle portion of the buffer operation member 301 and one side of the upper surface of the furniture 20 and provides an elastic force for buffering the buffer operation member 301, . The second elastic member 303 is configured such that a hypothetical line connecting one end portion and the other end portion of the second elastic member 303 with respect to the position where the shock absorbing operation member 301 is caught by the stopper 302, It is obvious that the buffer operation member 301 should be kept in a rotated state by being biased toward the opening direction side.

A shock absorber 305 for buffering the force at the time of closing the sliding door 10 is provided at a position not interfering with the second elastic member 303 between the intermediate portion of the buffering operation tool 301 and the upper surface of the furniture 20 ) Can be connected. To this end, it is obvious that the shock absorber 301 must be designed such that the second elastic member connecting position and the shock absorber connecting position are opposite to each other.

The operation of the sliding door for furniture according to the preferred embodiment of the present invention will now be described.

The first roller 103 and the second roller 203 are moved in a direction in which the sliding door 10 is opened while holding one side of the sliding door 10, The sliding door 10 is positioned at the rounded end of the rail 22 and moves along the first rail 21 and the second rail 22 in a straight line section and the sliding door 10 is moved to the upper side of the opposite sliding door So that it can be opened.

The connecting bar 121 rotatably connected to the first fixing bracket 101 is rotated in the first roller structure 100 as the sliding door 10 moves upward of the opposite sliding door, The first roller 103, the auxiliary roller 122 and the second roller 203 are arranged in a straight line in the horizontal direction and the sliding door 10 is opened naturally.

When the sliding door 10 is closed, the first roller 103 is moved to the end portion of the first rail 21 having a rounded end portion so that the connecting bar 121 can naturally move to the first fixing bracket 101, The closing operation of the sliding door 10 is naturally performed without a load.

At this time, in the auxiliary roller structure 120 in which the auxiliary roller 122 is rotatably connected, the end of the connecting bar 121 is inclined in the opposite direction to the position of the sliding door 10, The sliding door 10 is pulled in a direction opposite to the downward direction so that the sliding door 10 is moved downwardly in the downward direction as a result of being moved along the first rail 21 in a state tilted in the opposite direction of the door position It prevents you from striking.

Since the end portion of the connection bar 121 is inclined in the opposite direction to the sliding door position, the connection bar 121 is rotated about the first fixing bracket 101 when the sliding door 10 is moved, The first roller 103 and the auxiliary roller 122 are lowered by the inclination of the structure 120. The first roller bracket 102 is fixed to the first fixing bracket 101 Since the first elastic member 104 in the form of a compression coil spring is interposed in the shaft 122a of the first roller bracket 102 while the shaft 122a connected to the first roller bracket 102 is constructed of a double pipe type so that the sliding door The connection bar 121 is rotated according to the position of the auxiliary roller structure 120 and the first roller 103 is always pressed against the surface of the first rail 21 without being lifted even if the inclination of the auxiliary roller structure 120 is slightly changed When the stable opening and closing operation of the sliding door 10 is performed It becomes effective.

When the sliding door 10 is opened, the shaft 202a of the second roller bracket 202 moves along the second rail 22 at the second roller structure 200, And the buffering operation tool 301 is rotated to the position where it is caught by the stopper 302 and stopped by the stopper 302. The guide groove 301 is in contact with the shaft 202a of the second roller bracket 202 The sliding door opening direction side of the second roller bracket 304 is formed only up to a position where it does not interfere with the shaft 202a of the second roller bracket 202 with respect to the position where the buffering operation tool 301 is caught by the stopper 302, The shaft 202a of the sliding door 202 is free in a direction in which the sliding door 10 is opened and does not interfere with the opening operation of the sliding door 10. [

At the same time, the second elastic member 303 extends to the top dead center according to the rotation of the buffer actuating member 301 and contracts while exceeding the top dead center. Thus, when the buffer actuating member 301 is stopped by the stopper 302, 2 The buffering operation tool 301 is not rotated again by the elastic force of the elastic member 303, and the state in which the buffering operation tool 301 is caught by the stopper 302 can be maintained.

When the sliding door 10 is moved in the closing direction, the shaft 202a of the second roller bracket 202 is brought into contact with the sliding door closing direction side of the guide groove 304 to rotate the buffering operation tool 301 The second elastic member 303 is extended to the top dead center according to the rotation of the buffer actuating member 301 and then shrinks beyond the top dead center so that the closing force of the sliding door 10 can be firstly buffered And the shock absorber 305 connected to the shock absorber 301 is contracted when the shock absorber 301 is rotated to secondarily absorb the closing force of the sliding door 10 so that the sliding door 10 is closed, The closing force of the sliding door 10 can be completely reduced. Accordingly, noise can be prevented from being generated when the sliding door 10 is closed, and the sliding door 10 can be completely closed.

When the sliding door 10 is closed, the shaft 202a of the second roller bracket 202 is continuously inserted into the guide groove 304 of the shock absorbing member 301, As a result, the cushioning operation tool 301 holds the shaft 202a of the second roller bracket 202 in a state in which the sliding door 10 is closed as a result of the elasticity of the elastic member 303 So as to prevent the sliding door 10 from hitting downward.

On the other hand, when the sliding door 10 is large in size and relatively small in the size of the rails 21 and 22, the rollers 103, 122, The sliding door 10 may descend in a downward direction and cause a safety accident.

As shown in FIG. 8, in the present invention, a derailment preventing rail 400 is provided at a position close to the sliding door of the furniture 20, and a connection bar 121 and a second fixing bracket 201 are provided with a "L Preventive roller 401 is rotatably mounted on each of the derailleur roller rotatable shafts while being in contact with the lower surface of the derailleur prevention rail 400. In this configuration, The derailment preventing roller 401 comes into rolling contact with the lower surface of the derailleur prevention rail 400 during the opening and closing operation of the sliding door 10 so as not to interfere with the opening and closing operations of the sliding door 10 at all, Since the derailment preventing roller 401 is in contact with the lower surface of the derailleur prevention rail even when a strong force is generated during opening and closing, it is restricted to move the sliding door 10 in the upward direction, There is an advantage that safe use is enabled.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.
