  However, in the drawer device described in the above-mentioned Patent Document 1, the inner drawer is unlocked while the drawer is being pulled out, and only the drawer can be pulled out. However, the unlocked inner drawer is located above the drawer. There was no obstacle to the work of storing and taking out articles in the drawer. When storing and taking out articles in the drawer, there is an inconvenience that the drawn out drawer must be closed.

  The present invention has been made in view of such circumstances, and after the inner drawer pulled in conjunction with the drawer pulling operation is cut off at the limit of the drawer, the inner drawer is automatically retracted in the closing direction. It is an object of the present invention to provide a drawer device that can be used.

In order to solve the above-mentioned problems, the present invention firstly has a drawer, an inner drawer disposed inside the drawer, and the drawer operation of the inner drawer is interlocked with the drawer up to the drawer limit of the inner drawer. The internal drawer interlocking means for cutting off the interlock of the internal drawer when the drawer limit is exceeded, and the internal drawer retracting means for retracting the internal drawer in the closing direction after the interlock of the internal drawer is cut off by the internal drawer interlocking means. In the drawer device, the inner drawer retracting means is constituted by an elastic member on which an elastic force acts in a direction to close the inner drawer .

Secondly, the invention relates to a drawer, an inner drawer disposed inside the drawer, and the drawer operation of the inner drawer is interlocked with the drawer until the drawer limit of the inner drawer. Inner drawer interlocking means for cutting off the interlocking of the drawers, and an inner drawer retracting means for retracting the inner drawers in the closing direction after the interlocking of the inner drawers is cut off by the inner drawer interlocking means. However, it is characterized by being comprised from the magnet which a repulsive force acts in the direction which closes an inner drawer .

Thirdly, in addition to the first or second feature, the invention of the present application is characterized in that the inner drawer interlocking means includes a switching means for switching between interlocking with the withdrawal of the inner drawer and its release .

According to the drawer device having the first or second feature of the present invention, the inner drawer can be pulled out in conjunction with the drawer operation of the drawer, and the linkage can be cut off at the drawer limit of the inner drawer. After cutting off the interlock, the inner drawer can be retracted in the closing direction. When the articles are stored in and taken out from the drawer, the inner drawer does not get in the way and the operation can be performed smoothly.

According to the drawer device having the third feature of the present invention, it is possible to switch between interlocking and releasing of the inner drawer when the drawer is pulled out, and it is possible to pull out only the drawer.

  FIG. 1 is a longitudinal sectional view showing an outline of an embodiment of a drawer device of the present invention.

  The drawer device 1 is incorporated in a cabinet 2. The drawer device 1 includes a drawer 3 that can be moved back and forth, and an inner drawer 4 that can also be moved back and forth. Both the drawer 3 and the inner drawer 4 can store and take out articles. The inner drawer 4 is disposed inside the drawer 3.

  In this drawer device 1, a permanent magnet 6 is provided on the back surface of the door 5 of the drawer 3, and a permanent magnet 7 on which a magnetic force in a direction attracting the permanent magnet 6 acts is provided on the front surface portion 8 of the inner drawer 4. . Further, in the drawer 1, the maximum drawer length A of the drawer 3 is longer than the maximum drawer length B of the inner drawer 4. That is, there is a relationship of A> B. These permanent magnets 6 and 7 and the relationship A> B of the maximum drawing lengths of the drawer 3 and the inner drawer 4 constitute an inner drawer interlocking means.

  When the drawer 3 and the inner drawer 4 are closed, the permanent magnets 6 and 7 are attracted to each other, and the inner drawer 4 is connected to the drawer 3. For this reason, when the drawer 3 is pulled out, the inner drawer 4 is also pulled out in conjunction with the movement. The linkage between the drawer 3 and the inner drawer 4 is continued until the maximum drawer length B of the inner drawer 4 is reached. On the other hand, the maximum drawer length B of the inner drawer 4 is the drawer limit of the inner drawer 4, and beyond this, the inner drawer 4 cannot move further forward. When the force for pulling out the drawer 3 exceeds the attracting force of the permanent magnets 6 and 7, the permanent magnet 6 is separated from the permanent magnet 7, and only the drawer 3 is pulled out by the difference AB between the maximum drawing lengths A and B. be able to.

  In this way, the inner drawer interlocking means interlocks the drawer operation of the inner drawer 4 with the drawer 3 up to the drawer limit of the inner drawer 4, and cuts off the interlock operation of the inner drawer 4 when the drawer limit is exceeded.

  It should be noted that the inner drawer 4 can be provided with a mark 9 for marking the maximum drawer length B on its side. Therefore, when the inner drawer 4 is pulled out, the drawer 3 may be pulled out until the mark 9 is visible. When only the drawer 3 is pulled out, the mark 9 is confirmed, and the drawer 3 may be further pulled out.

  Further, the permanent magnets 6 and 7 can be provided only on one of the drawer 3 and the inner drawer 4. In this case, the other can be a magnetic body other than the permanent magnet. Further, one of the permanent magnets 6 and 7 may be an electromagnet.

  The drawer device 1 shown in FIG. 2 is based on the drawer device 1 shown in FIG. The same reference numerals are given to the same components as those shown in FIG.

  In the drawer device 1 shown in FIG. 2, the rail 10 that guides the longitudinal movement of the inner drawer 4 is inclined so that the back side is lowered. In other words, as shown in FIG. 2 <a>, the rail 10 is inclined obliquely downward by an angle θ toward the far side with respect to the horizontal direction. In the drawer device 1 shown in FIG. 2, the rail 10 is used as an inner drawer retracting means. The inner drawer retracting means retracts the inner drawer 4 in the closing direction after the interlock operation of the inner drawer 4 with the drawer 3 is cut off by the inner drawer interlocking means.

  As described above, when the drawer 3 is pulled out beyond the pull-out limit of the inner drawer 4, the permanent magnets 6 and 7 are separated, and the connection between the inner drawer 4 and the drawer 3 is released. Then, since the rail 10 is inclined so that the back side is lowered, the inner drawer 4 cannot stay at the limit of the drawer, and, as shown in FIG. For example, it automatically moves backward along the inclination of the rail 10. Therefore, since the inner drawer 4 is not located above the drawer 3, the inner drawer 4 does not get in the way when an article is stored in or taken out from the drawer 3. The operation of storing and taking out articles from the inside of the drawer 3 can be performed smoothly.

  In the drawer device 1 shown in FIG. 2, the rail 10 that guides the longitudinal movement of the inner drawer 4 is inclined obliquely downward as described above. Therefore, the inner drawer 4 is pulled out to its drawer limit. 3 is moved obliquely upward with the pull-out operation of 3. Therefore, a roller magnet is used for one of the permanent magnets 6 and 7 so that the connection between the inner drawer 4 and the drawer 3 is not released up to the limit of the drawer 4 so that the permanent magnets 6 and 7 are not separated. It is preferable to do.
