A pair of running paths 51 and 52 are used to support the moving inner drawer 30 from the front plate 31 side. As shown in FIGS. 1, 4, and 5, each of the pair of running paths 51, 52 is fixed between the front plate 21 and the rear plate 22. As shown in FIGS. A part of each running path 51, 52 (more specifically, between the first position P1 and the fifth position P5) (see FIG. 5) is provided for the corresponding first rotating rollers 56, 57. Running surfaces 51a and 52a are formed.

Here, as a method of installing each of the running paths 51 and 52, a method of fixing them to the upper portions of the corresponding side plates 23 and 24 may be adopted. That is, it is sufficient that each of the pair of running paths 51 and 52 is supported by the main drawer 20 and extended in the drawer direction AR1.

Each of the pair of first rotating rollers 56, 57 is a mechanical element used to move the inner drawer 30 relative to the main drawer 20, similar to the second rotating rollers 33a, 34a. As shown in FIGS. 4 and 5, the first rotating rollers 56 and 57 are provided on the side of the bottom plate 35 of the inner drawer 30 and rotate along the running surfaces 51a and 52a of the corresponding running paths 51 and 52. It is possible.

Each of the third side surfaces 63 and 64 is connected to the running surfaces 51a and 52a of the corresponding running paths 51 and 52, respectively.

Thereby, each of the third side surfaces 63, 64 can guide the corresponding first rotating rollers 56, 57 in a direction away from the main drawer 20 (more specifically, obliquely upward). That is, the first restricting portions 61 and 62 can suppress the rotation of the first rotating rollers 56 and 57 due to the increase in potential energy.

In this way, the first restricting portions 61 and 62 prevent the inner drawer 30 from moving toward the front plate 21 side of the main drawer 20 (more specifically, the tips 71c and 71c of the corresponding interlocking claws 71 and 72). movement of the inner drawer 30 so that the position 72c is closer to the front plate 21 than the third position P3). As a result, the inner drawer 30 is stopped near the position of the pair of interlocking claws 71 and 72 at the third position P3.

The pair of third restricting portions 38 and 39 are blocks for inhibiting the movement of the inner drawer 30 moving toward the front plate 21 of the main drawer 20 .

As a result, when the inner drawer 30 is moved and the position of the pair of interlocking claws 71 and 72 becomes the third position P3 (see FIG. 4), the pair of third restricting portions 38 and 39 are aligned with each other. In cooperation with the first restricting portions 61 and 62, the inner drawer 30 is restricted from moving further toward the front plate 21 from the third position P3. As a result, the inner drawer 30 is stopped near the position of the pair of interlocking claws 71 and 72 at the third position P3.

The pair of second restricting portions 81 and 82 are blocks for inhibiting the movement of the inner drawer 30 moving toward the back plate 7 of the cabinet body 5 . As shown in FIG. 6 , each of the pair of second restricting portions 81 and 82 is provided adjacent to the corresponding travel paths 51 and 52 similarly to the pair of third restricting portions 38 and 39 .

More specifically, the second restricting portion 81 is arranged on the opposite side of the side plate 8 (see FIG. 1) of the cabinet body 5 with the travel path 51 interposed therebetween. The second restricting portion 82 is arranged on the opposite side of the side plate 9 (see FIG. 1) of the cabinet body 5 with the travel path 52 interposed therebetween. Further, as shown in FIGS. 4 to 8 , stoppers 81 a and 82 a corresponding to the pair of second restricting portions 81 and 82 are provided on the bottom plate 35 side (lower side) of the inner drawer 30 .

As a result, when the inner drawer 30 is moved and the position of the pair of interlocking claws 71 and 72 is moved from the second position P2 to the fourth position P4 closer to the back plate 7 of the cabinet body 5 (see FIG. 5), Each of the pair of second restricting portions 81 and 82 restricts the movement of the inner drawer 30 that attempts to move further toward the back plate 7 side from the fourth position P4. As a result, the inner drawer 30 is stopped near the position of the pair of interlocking claws 71 and 72 at the fourth position P4.

<2. Configuration of Interlocking Mechanism>
Each of FIGS. 9 to 11 is a perspective view showing an example of the configuration around the interlocking mechanism 70. FIG. Here, the interlocking mechanism 70 fixes the inner drawer 30 to the main drawer 20 when the pair of first rotating rollers 56 and 57 are positioned near the first position P1 (see FIGS. 4 and 5). state. As shown in FIGS. 9 to 11, the interlocking mechanism 70 mainly has a pair of interlocking claws 71 and 72, a link mechanism 73, and urging portions 76 and 77, respectively. For convenience of explanation, the side plates 33 and 34 are omitted from FIG. 9, and the front plate 31 and the side plates 33 and 34 are omitted from FIGS. 10 and 11, respectively.

Each of the pair of interlocking claws 71 and 72 is used for a return operation for interlocking the inner drawer 30 with the main drawer 20 and an operation for releasing the interlocked state between the main drawer 20 and the inner drawer 30. is an element.

As shown in FIGS. 7 and 8, each of the pair of interlocking claws 71 and 72 extends in a direction from the bottom plate 35 of the inner drawer 30 toward the running paths 51 and 52 (hereinafter simply referred to as "first projecting direction"). ) can advance and retreat along AR2.

Here, the inner drawer 30 is moved, and the positions of the pair of interlocking claws 71 and 72 are shifted from the second position P2 (that is, the position closer to the back plate 7 of the cabinet body 5 than the first position P1) to the first position P1. , the first side surfaces 71a and 72a of the interlocking claws 71 and 72 come into contact with the third side surfaces 63 and 64 of the corresponding first restricting portions 61 and 62, respectively. Further, in the present embodiment, the first side surfaces 71a and 72a are inclined surfaces that follow the third side surfaces 63 and 64 of the corresponding first restricting portions 61 and 62, respectively.

Therefore, when the inner drawer 30 is moved so that the pair of interlocking claws 71 and 72 move from the second position P2 to the first position P1, the tips 71c and 72c of the interlocking claws 71 and 72 move to the corresponding first positions. It is pushed upward by one side surface 71a, 72a (see FIGS. 4, 7 and 8).

The link mechanism 73 is used to manually move the interlocking claws 71 and 72 away from the corresponding first restricting portions 61 and 62 . As shown in FIGS. 9 to 11, the link mechanism 73 mainly has a selector switch 73a, a transmission rod 73b, and cams 74a and 74b.

The changeover switch 73a is an operation knob for receiving an operation from the user of the cabinet 1 (hereinafter simply referred to as "user"). The transmission rod 73b is a rod extending in a direction (parallel to the Y-axis) perpendicular to each of the pull-out direction AR1 and the first projecting direction AR2 (direction parallel to the Z-axis). A switch 73a is fixed.

Further, the transmission rod 73b is provided so as to be rotatable with respect to the side plates 33, 34 (see FIG. 1). Furthermore, cams 74 a and 74 b (corresponding to the interlocking claws 71 and 72 , respectively) are connected to both ends of the link mechanism 73 in a state of interlocking with the link mechanism 73 . Thus, when the user rotates the switch 73a in the rotation direction R1 (see FIG. 10), the tips of the interlocking claws 71 and 72 are moved upward.

Each of the pair of biasing portions 76 and 77 is an elastic member configured by, for example, a compression spring. As shown in FIGS. 7 and 8, one end 76a, 77a of each biasing portion 76, 77 is connected to the corresponding interlocking claw 71, 72. As shown in FIG. Further, the other ends 76b, 77b of the urging portions 76, 77 are connected to corresponding fixing portions 36, 37 provided on the inner drawer 30, respectively.

Therefore, the inner drawer 30 is moved so that the positions of the pair of interlocking claws 71 and 72 are moved from the second position P2 to the first position P1, and the tips 71c and 72c of the interlocking claws 71 and 72 move to the corresponding first positions. When pushed upward by the side surfaces 71a and 72a, the urging portions 76 and 77 are compressed (see FIGS. 8 and 11). Therefore, each of the interlocking claws 71 and 72 is urged downward by the corresponding urging portions 76 and 77 .

Further, when the user rotates the switch 73a in the rotational direction R1 (see FIG. 10), the tips of the interlocking claws 71 and 72 are moved upward, and the urging portions 76 and 77 are compressed. (See FIGS. 8 and 11). Therefore, the interlocking claws 71 and 72 are urged downward by the corresponding urging portions 76 and 77 in the same manner as when the inner drawer 30 is moved.

<3. Interlocking Return Operation and Interlocking Release Operation of Inner Drawer by Interlocking Mechanism>

In addition, in the interlocking return operation and the interlocking release operation, similar operations are performed in the vicinity of the interlocking claws 71 and 72 . Therefore, only the operation near the interlocking claw 71 will be described in this embodiment.

First, the interlocking return operation will be described. The interlocking return operation of the inner drawer 30 by the interlocking mechanism 70 is performed by the following procedure. That is, due to the movement of the inner drawer 30, the interlocking claw 71 reaches the first position P1 from the second position P2 (see FIG. 12).

Then, the tip 71c of the interlocking claw 71 is moved toward the bottom plate 35 while the first side surface 71a (see FIGS. 7 and 8) of the interlocking claw 71 is in contact with the corresponding first restricting portions 61 and 62. As shown in FIG. As a result, the biasing portion 76 biases the corresponding interlocking claw 71 .

Subsequently, the interlocking claw 71 reaches the third position P3 (the position closer to the front plate 21 of the main drawer 20 than the first position P1) from the first position P1 (FIGS. 13 and 14). As a result, the contact state between the interlocking claw 71 and the corresponding first restricting portion 61 is released. Further, the tip 71 c of the corresponding interlocking claw 71 is moved away from the inner drawer 30 by the biasing force from the biasing portion 76 .

Therefore, the second side surface 71 b (a side surface different from the first side surface 71 a ) of the interlocking claw 71 can come into contact with the corresponding first restricting portion 61 . As a result, the inner drawer 30 is interlocked with the main drawer 20 (that is, the inner drawer 30 is pulled out from the cabinet main body 5 together with the main drawer 20 following the pull-out operation of the main drawer 20). .

On the other hand, the interlocking release operation of the inner drawer 30 by the interlocking mechanism 70 is executed by the following procedure. That is, when the position of the pair of interlocking claws 71 and 72 is set to the third position P3 and the main drawer 20 and the inner drawer 30 are interlocked (see FIG. 14), the interlocking claws 71 and 72 are connected to the link. It is separated from the corresponding first restricting portions 61, 62 by a mechanism 73 (Fig. 13). As a result, the contact state between the first restricting portion 61 and the second side surface 71b is released (see FIG. 8), and the inner drawer 30 can move toward the back plate 7 of the cabinet body 5. As shown in FIG. In other words, the inner drawer 30 is in a disengageable state.

Therefore, when the inner drawer 30 is moved along with the separation operation from the first restricting portions 61 and 62, the interlocking claw 71 is moved from the third position P3 to the second position P2 via the first position P1. can be done. In this manner, the interlocking release operation of the inner drawer 30 is realized by operating the link mechanism 73 to retract the interlocking claw 71 upward, and then moving the inner drawer 30 toward the back plate 7 of the cabinet body 5 . can.
