FIG. 4 is a front view of a double- And the roller unit moves to the left side.

1 to 4, a bidirectional damper for a sliding built-in intermediate door according to an embodiment of the present invention includes:

A roller portion 110 formed with an engaging portion 111 for engaging with the intermediate door and movable left and right and having first and second retaining rings 112 and 114 facing each other in opposite directions;

A first moving body 130 which is engaged with the first latching ring 112 and moves together when the roller 110 moves to the right;

A second moving body (160) which moves together with the second latching ring (114) when the roller unit moves to the left;

A main body 120 having rails 121 for guiding left and right movement of the roller unit 110 and having fixing portions 122 in both lower ends thereof;

A first spring 140 connected to the fixing part 122 at one side and connected to the first moving body 130 at the other side;

A first piston 150 having one side connected to the fixed portion 122 and the other side connected to the first moving body 130;

A second spring 170 connected to the fixing part 122 at one side and connected to the second moving body 160 at the other side;

And a second piston 180 connected to the second moving body 160 at one side thereof.

The roller unit 110 may further include a bearing 113 that is movable on the rail, and a wheel or other means may be used instead of the bearing.

The first and second moving bodies 130 and 160 are formed with first and second fastening portions 131 and 161 for fastening the first and second fastening rings 112 and 114, respectively.

The center portion of the rail 121 formed on the main body 120 is formed flat without inclination and both ends of the rail 121 are inclined downward at a predetermined angle.

The first and second moving bodies 130 and 160 are provided with grooves 132, 133 and 162 for coupling the first and second springs 140 and 170 and the first and second pistons 150 and 180, And the grooves 132, 133, 162, and 163 are cylindrical, and the ends of the grooves 132, 133, 162, and 163 are formed in a spherical shape.

The portions of the first and second springs 140 and 170 and the first and second pistons 150 and 180 that engage with the first and second moving bodies 130 and 160 are engaged with the grooves 132, 162, and 163, and the end portion is formed in a spherical shape.

The operation of the bidirectional damper for an intermediate door of a sliding built-in cabinet according to an embodiment of the present invention having such a configuration is as follows.

Referring to FIG. 3, when the intermediate door is moved to the left by the user, the roller unit 110 moves to the left along the rail 121. At this time, the latching part 131 is hooked on the first latching ring 112, so that the first moving body 130 also moves to the left.

As a result, the intermediate door is moved at a speed that is stronger than the expansion force of the first piston 150 due to the tensile force of the first spring 140 connected to the first moving body 130.

At this time, when the movement to the left is almost completed, the end of the rail 121 is fixed as long as a predetermined force is not applied in the opposite direction by the inclination.

In this state, when the user moves the intermediate door to the right, the first hooking ring 112 is hooked on the hooking part 130, so that the first moving body also moves to the right side.

Here, in the rightward movement, the engagement force of the engagement portion 131 with the first engagement ring 112 is weak due to the structure of the engagement ring, but the force of the first spring 140 connected to the first movement body 130 contracts And helps to move to the right.

Next, when the roller unit 110 moves rightward to the middle of the rail 121 and then moves rightward, the engaging force of the first latching ring 112 and the latching unit 131 is weakened as shown in FIG. A fixing structure may be provided to prevent the first moving body 130 from moving to the right side if necessary.

On the other hand, when the intermediate door is moved to the right side, the roller unit 110 moves to the right along the rail 121. At this time, the second retaining ring 114 is caught by the retaining portion 161, and the second moving body 160 also moves to the right.

The tensile force of the second spring 170 connected to the second moving body 160 is stronger than the expansion force of the second piston 180 so that the intermediate door moves at a smooth speed.

At this time, when the movement is almost completed to the right, the end of the rail 121 is fixed as long as a predetermined force is not applied in the opposite direction by the inclination.

In this state, when the user moves the intermediate door to the left side, the second hooking ring 114 is caught by the hooking portion 161 and the second moving body 160 is also moved to the left. In this case, the second hook 170 connected to the second moving body 160 is contracted by the force of the second hooking ring 114 to engage with the engaging portion 161 in the leftward movement, .

By repeating this process, the intermediate door can be moved to the left or right at any time.

In the embodiment of the present invention, the moving body is positioned at the lower end of the roller portion, and a space is occupied by a simple structure in which the spring and the piston are connected to each other.

In addition, in the embodiment of the present invention, when the sliding sliding door is closed, the shock due to the moving energy of the door is alleviated to prevent noise, and the door can be prevented from being opened again by itself due to the impact.

The present invention is not limited to the above-described embodiments, and various modifications may be made within the scope of the technical idea of the present invention.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And all changes to the scope that are deemed to be valid.
