The lower compartment 344 extends from the front end of the lower case 340 to the front end of the lower opening 342 and is preferably formed in a shape corresponding to the vertical downward corresponding to the upper compartment 326. something to do.

Accordingly, the inner part of the case 300 may be divided into two spaces by the upper compartment 326 and the lower compartment 344, and the compression member 500 and the damper 400 are mounted in respective spaces. As a result, the autocloser 200 may be formed as an assembly by the case 300.

On the left side of the lower case 340, more specifically, the left end (upper surface in FIG. 7) of the lower opening 342 is formed with a guide portion 360 protruding upward. The guide portion 360 is formed in a plate shape having a predetermined height to guide the restraint mechanism 700 to be described below. Description of the guide unit 360 will be described again below.

At the rear end (right side in FIG. 7) of the lower surface opening 342, a plate-shaped support end 346 is further formed. The support end 346 supports the compression member 500 to be described below, thereby limiting the rear movement of the compression member 500 and the damper 400.

A damper 400 is provided at one side of the case 300. The damper 400 is to alleviate the impact generated when the drawer 120 is drawn in. The cylinder 420 is formed in a cylindrical shape having a predetermined length and a rod protruding from the inside of the cylinder 420. 440. Since the configuration of the damper 400 is the same as that of the general damper 400, a detailed description thereof will be omitted.

The damper 400 is accommodated in a space formed by the upper compartment 326 and the lower compartment 344, and the rear end of the rod 440 is mounted on the rear surface of the case 300. Accordingly, the cylinder 420 faces forward, and the cylinder 420 also moves forward and backward as the slide rails 140 are pulled out and closed.

On the other hand, the second half of the damper 400 is coupled to the compression member 500. The compression member 500 is moved forward and backward in association with the movement of the sliding rail 140, and the elastic member 600 is compressed during the front movement.

The elastic member 600 is to provide an elastic force for the automatic retracting of the drawer 120, that is, the sliding rail 140, is interposed between the rear end of the case 300 and the compression member 500. Composed of a compression spring is compressed and stretched inside the case 300 in accordance with the movement of the compression member 500.

Looking at the configuration of the compression member 500 in more detail with reference to Figure 8 as follows. 8 is an exploded perspective view showing the structure of a damper, a compression member, and a restraint mechanism, which are main components of a furniture auto closer according to the present invention.

As shown in the drawing, the compression member 500 includes a coupling part 520, an extension part 540, and a support part 560.

The coupling part 520 allows the compression member 500 to be coupled to the cylinder, and one side contacting the cylinder 420 is formed in a curved surface corresponding to the outer circumferential surface shape of the cylinder 420. It is in close contact with the cylinder 420.

And, on the other side of the coupling portion 520 is mounted a restraint mechanism 700 to be described in detail below. To this end, the other side of the coupling part 520 is formed to correspond to the shape of the restraint mechanism 700, and a rotation shaft penetrating through one side of the restraint mechanism 700 so that the restraint mechanism 700 can be rotatably mounted ( 522 protrudes laterally.

The rear side portion of the coupling part 520 protrudes laterally to have the same height as the restraint mechanism 700 when the restraint mechanism 700 is mounted, and is in surface contact with the inner surface of the guide part 360.

Therefore, a lubricant groove 524 recessed inward is formed in the second half of the coupling part 520 in contact with the guide part 360. The lubricant groove 524 is a place where the lubricant to reduce the friction during the movement of the compression member 500 is stored in a plurality at regular intervals, it will be preferable to be formed long in the movement direction of the compression member 500. .

On the other hand, the restraint mechanism 700 is mounted on the outer surface of the coupling portion 520. The restraint mechanism 700 is selectively coupled with the rail pin 142 to allow the compression member 500 and the damper 400 to selectively interwork with the sliding rail 140, and the drawer 120. At the time of introduction, the damping force by the damper 400 is transmitted to the sliding rail 140.

The restraint mechanism 700 is largely composed of a rotating part 720 and the receiving part 740. The rotating part 720 is formed in a substantially fan shape and is mounted to be in surface contact with one side of the coupling part 520. At this time, the rotating part 720 is inserted into the rotating shaft 522 into the mounting hole 722 formed through the lower portion of the central portion of the rotating part 720, accordingly, the restraint mechanism 700 has a rotatable structure do.

At this time, the restraint mechanism 700 is mounted on one side of the coupling part 520 perpendicular to the upper and lower surfaces of the case 300, so that the left and right spaces inside the case 300 when the restraint mechanism 700 is rotated. It is not restricted, and is free to rotate by the upper opening of the restraint mechanism 322. However, the rotation of the restraint mechanism 700 is partially limited by the guide part 360 to be described in detail below.

In addition, an accommodation part 740 protruding upward is formed at approximately the center of the upper end of the rotating part. The receiving portion 740 is formed in a substantially 'U' shape (see FIG. 8), and is formed in a corresponding shape so that the rail pin 142 may be accommodated therebetween.

At this time, the protrusions on the left side (in FIG. 8) of the protrusions on both sides of the receiving portion 740 are formed to have a lower height. The rail pin 142 is removed while rotating the restraint mechanism 700 when the sliding rail 140 is pulled out, and the rail pin 142 is interrupted when the sliding rail 140 is pulled out. This is to be coupled while rotating the mechanism 700.

On the other hand, the left side (in Figure 8) of the upper portion of the pivoting portion 720 is formed with a moving projection 724 protruding outward. The moving protrusion 724 moves while contacting the guide part 360 when the compression member 500 moves, and is formed in a rib shape having a predetermined length and width, and the moving protrusion 724 is downward. It is configured to support it.

In addition, a limiting protrusion 726 protruding to an inner side (the direction in which the damper is positioned) is formed on the right side (in FIG. 8) of the upper part of the pivoting unit 720. The limiting protrusion 726 is for limiting the rotation of the restraint mechanism 700 in one direction. When the restraint mechanism 700 rotates in a clockwise direction (in FIG. 8) of the restraint mechanism 700, Constrained to be able to rotate.

Meanwhile, referring to FIG. 9, the guide part 360 will be described in more detail. The guide part 360 guides the restraint mechanism 700, and the restraint mechanism 700 has a predetermined length. After the movement is rotated so that the coupling with the rail pins 142 can be released, and guide the restraint mechanism 700 to maintain the rotated state, the extension section 362 and the rotation section ( 364) and a fixed section 366.

The extension section 362 is a section for guiding the restraint mechanism 700 to move together with the compression member 500 to be moved in a non-rotated state and extends by a length corresponding to the stroke length of the damper 400. do.

A rotation section 364 is formed at the front end of the extension section 362. The rotation section 364 is formed to be round so that the restraint mechanism 700 can start the rotation, and is formed to be rounded vertically downward from the front end of the extension section 362.

Therefore, the restraint mechanism 700 may move to the end of the extension section 362 in a state in which it is coupled with the rail pin 142, and after moving up to the stroke of the damper 400, the rotation section ( By moving along the 364, the coupling with the rail pin 142 is released.

On the other hand, a fixed section 366 is formed at the lower end of the rotation section (364). The fixing section 366 is a portion formed to be inclined to correspond to the position of the moving protrusion 724 formed in the restraining mechanism 700 during the complete rotation of the restraint mechanism 700, the moving projection 724 is the fixed section When positioned in, the position of the compression member 500 is fixed so that the elastic member 600 can be fixed in a compressed state.

When the restraint mechanism 700 is rotated so that the moving protrusion 724 is located in the fixed section 366, the inclination of the fixed section 366 becomes approximately 45 °, and thus the restraint mechanism 700 is rotated. Receiving portion of the 740 is also toward the front at an approximately 45 ° angle, which is the rail pin 142 is easily accommodated in the receiving portion 740 when the sliding rail 140 is moved backwards the sliding rail 140 ) And the compression member 500 to interlock.

For example, although the guide part 360 is formed on the lower case 340, any position may be possible if the inside of the case 300 is formed, and the groove portion 360 is formed in a groove shape recessed inward rather than the rib shape described above. It could be. Of course, at this time, the shape of the moving protrusion 724 should also be changed to correspond thereto.

On the other hand, the support portion 560 is formed at the front end (left side in Figure 8) of the coupling portion 520. The support part 560 is in contact with the rear end of the elastic member 600 to be described below, and compresses the elastic member 600 when the compression member 500 moves. The support part 560 may be molded to form a surface perpendicular to the coupling part 520 at the front end of the coupling part 520 so as to stably support the rear end of the elastic member 600.

Meanwhile, an extension part 540 is formed at a front end of the coupling part 520, and more specifically, at an approximately center portion of the front surface of the support part 560. The extension part 540 is inserted into the elastic member 600, is formed in a round bar shape, and extends to a position corresponding to the front end of the cylinder 420.

Hereinafter, the operation of the furniture auto closer according to the present invention having the configuration as described above will be described with reference to the drawings.

9 to 12 is an exploded perspective view showing an operating state of the furniture auto closer according to the present invention.

As shown in these figures, the user manipulates the drawer 120 forwards and backwards to allow the drawer 120 to be pulled into / out of the furniture 100.

In this case, the sliding rail 140 is slid forward and backward together with the draw / input operation of the drawer 120, and thus the autocloser 200 is selectively interlocked so that the drawer 120 is automatically closed. Of course, the drawer 120 to mitigate the shock when the closing.

The above-described schematic operation will be described below with reference to the drawings.

9 illustrates the state of the autocloser 200 when the drawer 120 is fully retracted. As shown in the figure, in the state in which the drawer 120 is fully retracted, the sliding rail 140 is also fully retracted, and the rail pin 142 formed in the sliding rail 140 is the restraint mechanism ( It is accommodated in the receiving portion 740 of the 700 is in a state that the compression member 500 and the sliding rail 140 can interlock.

In addition, the compression member 500 and the damper 400 are completely accommodated inside the case 300. That is, the rear end of the compression member 500 is in contact with the support end 346, the elastic member 600 inserted into the extension portion 540 of the compression member 500 is to maintain a normal state uncompressed. . The rod 440 of the damper 400 is in contact with the rear surface (left side in FIG. 9) of the case 300 while the rod 440 is completely inserted into the cylinder 420. In this state, the extension part 540 of the compression member 500 and the cylinder 420 of the damper 400 do not protrude forward of the case 300.

On the other hand, when the user pulls the drawer 120 forward and starts to draw out, the sliding rail 140 is slidably moved forward, and thus the autocloser 200 starts to operate.

When the sliding rail 140 moves forward, the rail pin 142 mounted on the sliding rail 140 also moves forward, and the receiving portion 740 coupled to the rail pin 142 is also moved. The sliding rail 140 is moved forward and the restraint mechanism 700 in which the receiving portion 740 is formed is coupled to the compression member 500, so that the compression member 500 includes the sliding rail ( 140) and move forward. In addition, the compression member 500 is moved together when the sliding rail 140 is moved in a state coupled with the damper 400.

The extension part 540 of the compression member 500 is moved forward through the extension part through hole 328 formed in the case 300 by the forward movement of the compression member 500, and thus the case ( Compression of the elastic member 600 interposed between the inside of the 300 and the support 560 is started.

At the same time, the cylinder 420 of the damper 400 is also moved forward so that the cylinder 420 moves forward through the cylinder through hole 329 of the case 300, and thus the cylinder is relatively moved. A piston (not shown) inside 420 is moved backwards.

On the other hand, when the sliding rail 140 is continuously drawn out forward, the restraint mechanism 700 is moved forward in the state coupled with the rail pin 142 along the extension section of the guide portion 360. When the sliding rail 140 is moved by a predetermined distance (preferably the maximum compression distance of the elastic member and the stroke of the damper), the moving projection 724 of the restraint mechanism 700 is the guide portion 360 Enter the meeting section of.

In the rotation section 364, the restraint mechanism 700 is no longer able to move forward, and in this state, the rail pin 142 moves forward according to the forward movement of the sliding rail 140. Then, the first half of the receiving portion 740 is pushed forward by the rail pin 142 and the restraint mechanism 700 is rotated counterclockwise around the rotation axis 522.

The state at this time is shown in FIG. 10, and when the sliding rail 140 is further drawn out, the restraint mechanism 700 further rotates to a state as shown in FIG. 11.

As shown in the figure, the rear end of the moving projection 724 of the restraint mechanism 700 in accordance with the rotation of the restraint mechanism 700 is continuously rotated in contact with the rotation section 364 by about 45 in a counterclockwise direction. Will be rotated.

After the restraint mechanism 700 rotates by about 45 ° in the counterclockwise direction, the moving protrusion 724 of the restraint mechanism 700 is positioned at the fixing section 366 of the guide part 360. At this time, the moving projection 724 is seated in the fixed section 366 of the guide portion 360, the moving projection 724 between the lower portion of the rotation section 364 and the fixed section 366. I get caught.

Accordingly, the restraint mechanism 700 is fixed in the fixing section 366 as long as no external force is applied thereto, thereby keeping the compression member 500 compressing the elastic member 600. . In this state, it is preferable that the elastic member 600 is compressed to the maximum and set to have the maximum elastic force of the elastic member 600.

On the other hand, in the state where the moving projection 724 of the restraint mechanism 700 is located in the fixing section 366, the rail pin 142 is separated from the receiving portion 740, the sliding rail 140 and the restraint In accordance with the continuous withdrawal of the drawer 120 while the mechanism 700 is released, the sliding rail 140 also continuously moves forward.

In addition, the extension part 540 of the compression member 500 and the cylinder 420 of the damper 400 pass through the extension part through hole 328 and the cylinder through hole 329 of the case 300, respectively. It protrudes as far forward as possible.

In the state in which the drawer 120 is withdrawn, the user performs an operation such as storing an object in the drawer 120, and after performing the work, pushes the drawer 120 to rear the sliding rail 140. Will be moved.

The sliding rail 140 continuously slides backward by a force applied to the drawer 120, and when the sliding rail 140 moves rearward by a predetermined distance, the case 300 of the case 300 is moved. The latter half of the receiving portion 740 and the rail pin 142 exposed through the restraint mechanism opening 322 formed on the upper surface come into contact with each other.

When the sliding rail 140 is moved backward while the rail pin 142 and the rear half of the receiving portion 740 are in contact with each other, the rail pin 142 pushes the rear half of the receiving portion 740 backwards. The restraint mechanism 700 rotates in a clockwise direction about the rotation shaft 522, and this state is illustrated in FIG. 12.

As the restraint mechanism 700 rotates in the clockwise direction, the moving protrusion 724 moves out of the fixed section 366 and enters the extension section 362 while contacting the rotating section 364. When the restraint mechanism 700 is rotated such that the moving protrusion 724 of the restraint mechanism 700 is supported by the extension section 362, the limiting protrusion 726 of the restraint mechanism 700 is extended to the extension section. Interfering with the top of 362, the restraint sphere 700 is no longer rotated clockwise.

On the other hand, at the moment when the moving protrusion 724 is released from the fixing section 366, the restraint of maintaining the elastic member 600 in the compressed state is released, so that the compression member 500 is applied to the restoring force of the elastic member 600. It is moved rearward by, the automatic closing of the sliding rail 140 is started by the rail pin 142 coupled with the restraint mechanism 700.

Automatic closing of the sliding rail 140 starting from the front end of the extension section 362 is continuously made to the position where the elastic member 600 is returned to its original state, and thus the drawer 120 Is completely inserted and closed.

In addition, the cylinder 420 of the damper 400 coupled with the compression member 500 also moves rearward as the compression member 500 moves backwards, so that the cylinder 420 moves rearward. Accordingly, the rod 440 is gradually inserted into the cylinder 420.

Therefore, a damping force is generated in the damper 400 by the oil filled in the damper 400, and the compression member 500 is prevented from rapidly moving backward by the elastic member 600. do. That is, the drawer 120 may be softened by the damper 400 and the drawer 120 may be smoothly closed.

In the state where the drawer 120 is completely retracted, the auto closer 200 is in a state as shown in FIG. 9 again.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.
