  When the main drawer 14 is pulled out from this stored state, the main drawer 14 starts to move in the drawing direction (the direction of arrow A in FIG. 10) by the slide member 20 and the rail member 21. 2, the back plate 14B of the main drawer 14 is engaged with the vertical surface 60E of the hook 60, and the slider 36 is pulled out from the rear end portion of the housing 26 (in the direction of arrow A in FIG. 10). Moving.

  At this time, as shown in FIG. 1, in the latch 50 of the slider 36, the stopper 50B is in contact with the rear portion 40A of the latch cam surface 40, and the latch 50 is pushed downward (the amount of upward protrusion is small). Is the least). For this reason, the leading end portion 50C of the latch 50 is an idle running section where it does not engage with the engaging recess 72 of the striker 70, and the slider 36 moves with the main drawer 14, but the inner drawer 16 does not move.

  For this reason, it is possible to reduce the pull-out force at the start of the pull-out of the main drawer 14. As a result, even when the main drawer 14 is provided with a closer, the pull-out force when the main drawer 14 starts to be pulled out can be reduced, and the operability is improved.

  Next, the main drawer 14 is further pulled out. As shown in FIG. 2, when the slider 36 reaches the intermediate portion in the longitudinal direction of the housing 26, the stopper 50B of the latch 50 is moved to the intermediate portion 40B in the front-rear direction of the latch cam surface 40. Abutting, the latch 50 is pushed upward (the amount of protrusion upward is the largest). For this reason, the front end portion 50C of the latch 50 engages with the front wall portion (vertical portion) 72A of the engaging recess 72 of the striker 70 to form an interlocking section. As a result, the inner drawer 16 moves along with the main drawer 14 in the drawer direction (the direction of arrow A in FIG. 2).

  In this interlocking section, the tip 50C of the latch 50 engages with the front wall portion (vertical portion) 72A of the engaging recess 72, so that the striker 70 is retracted with respect to the latch 50 (in the direction of arrow B in FIG. 2). Cannot move to. That is, the inner drawer 16 cannot be separated from the main drawer 14 in the storage direction (the direction of arrow B in FIG. 2).

Since the entire portion 72C is an inclined surface, the rear wall portion 72C of the engaging recess 72 and the inclined surface 50D of the latch 50 slide. As a result, the latch 50 moves downward against the urging force of the coil spring 52, so that the engagement between the latch 50 (main drawer 14) and the striker 70 (inner drawer 16) is released. That is, the inner drawer 16 can be forcibly separated from the main drawer 14 in the drawing direction (the direction of arrow A in FIG. 2).

Next, the main drawer 14 is further pulled out. As shown in FIG. 3, when the slider 36 reaches the front part of the housing 26, the stopper 50B of the latch 50 comes into contact with the front part 40C of the latch cam surface 40, 50 is pushed upward, but the upward protrusion amount is smaller than that of the interlocking section. For this reason, the front end portion 50 </ b> C of the latch 50 is a semi-interlocking section where the front wall portion (inclined portion) 72 </ b> B of the engaging recess 72 of the striker 70 is engaged.

  In this semi-interlocking section, if the striker 70 (inner drawer 16) is forcibly moved in the storage direction (in the direction of arrow B in FIG. 3) with respect to the latch 50 (main drawer 14), the tip 50C of the latch 50 and The front wall portion (inclined portion) 72B of the engaging recess 72 slides. As a result, the latch 50 moves downward against the urging force of the coil spring 52, so that the engagement between the striker 70 and the latch 50 is forcibly released.

  Therefore, if necessary, only the inner drawer 16 can be moved in the storage direction (the direction of arrow B in FIG. 3), and the opening area of the main drawer 14 can be increased.

  When the striker 70 (inner drawer 16) is forcibly moved in the drawing direction (the direction of arrow A in FIG. 3) with respect to the latch 50 (main drawer 14), the rear wall of the engaging recess 72 in the striker 70. The entire part 72C is an inclined surface. Therefore, the rear wall 72C of the engaging recess 72 and the inclined surface 50D of the latch 50 slide, and the latch 50 moves downward against the urging force of the coil spring 52, whereby the striker 70 and the latch 50 are moved. Can be forcibly released.

  Therefore, if necessary, only the inner drawer 16 can be moved in the drawer direction (the direction of arrow A in FIG. 3) to increase the opening area of the inner drawer 16.

  Next, the main drawer 14 is further pulled out. As shown in FIG. 4, when the slider 36 reaches the front end of the housing 26, the stopper 60B of the hook 60 comes into contact with the upper front end of the inclined portion 46B of the hook cam surface 46. The hook 60 is pushed upward. For this reason, the hook 60 moves upward from the back plate 14B of the main drawer 14. As a result, the engagement between the back plate 14B of the main drawer 14 and the slider 36 is released, so that the main drawer 14 is disengaged from the inner drawer 16, and the drawing direction is further extended as shown by a two-dot chain line in FIG. It can move independently (in the direction of arrow A in FIG. 4).

  When the main drawer 14 is moved from the drawer position indicated by a two-dot chain line in FIG. 4 in the storage direction (in the direction of arrow B in FIG. 4), the rear surface of the back plate 14B of the main drawer 14 is engaged with the protrusion 36C of the slider 36. To do. Therefore, the slider 36 moves in the storage direction (in the direction of arrow B in FIG. 4) along with the main drawer 14, and the inner drawer 16 is stored from the drawer position shown in FIG. 4 together with the striker 70 that engages the latch 50. Move in the direction (arrow B direction in FIG. 4).

  Further, when the slider 36 moves in the storage direction (the direction of arrow B in FIG. 4), the stopper 60B of the hook 60 moves downward along the inclined portion 46B of the hook cam surface 46. For this reason, the lower front end portion 60 </ b> C of the hook 60 moves downward from the back plate 14 </ b> B of the main drawer 14. As a result, when the main drawer 14 is moved in the drawer direction (the direction of arrow A in FIG. 3), the inner drawer 16 is interlocked with the main drawer 14.

  Further, when the main drawer 14 is moved in the storage direction (in the direction of arrow B in FIG. 4), it reaches the idle running section shown in FIG. 1 through the semi-interlocking section shown in FIG. 3 and the interlocking section shown in FIG. In the idle running section shown in FIG. 1, the engagement between the latch 50 and the engagement recess 72 is released, and the main drawer 14 and the inner drawer 16 are separated. As a result, after the inner drawer 16 stops at the storage position, only the main drawer 14 further moves in the storage direction (in the direction of arrow B in FIG. 1) and stops at the storage position shown in FIG.

  Therefore, in this embodiment, the main drawer 14 and the inner drawer 16 can be switched between interlocking and separation by adjusting the shape (height H1 to H3) of the latch cam surface 40 of the housing 26.

  Further, in the present embodiment, when the main drawer 14 is pulled out from the storage position, the housing 26 is operated until the slider 36 is pulled out from the storage direction end of the housing 26 in the pull-out direction by a predetermined distance as shown in FIG. The rear cam portion 40A of the latch 40 is an idle running section in which the latch 50 is not engaged with the striker 70 of the inner drawer 16. For this reason, since the inner drawer 16 does not move, the load when the main drawer 14 is pulled out from the storage position can be reduced.

  Further, in this embodiment, when the main drawer 14 is pulled out from the storage position, if the slider 36 moves in the pull-out direction from the storage direction end of the housing 26 by a predetermined distance or more, as shown in FIG. The back plate 14B engages with the vertical surface 60E of the hook 60, and the slider 36 moves forward (in the direction of arrow A in FIG. 2) together with the main drawer 14. As a result, the inner drawer 16 can be interlocked with the main drawer 14.

  Further, in the present embodiment, when the main drawer 14 is pulled out from the storage position, when the latch 50 is engaged with the striker 70 of the inner drawer 16 and the slider 36 moves more than a predetermined distance, as shown in FIG. The intermediate portion 40B in the front-rear direction of the latch cam surface 40 of the housing 26 provides a semi-interlocking section in which the engagement between the latch 50 and the striker 70 of the inner drawer 16 can be forcibly released. For this reason, in this semi-interlocking section, the engagement between the latch 50 and the striker 70 is forcibly released, so that only the inner drawer 16 moves in the storage direction (the direction of arrow B in FIG. 3) with respect to the main drawer 14. (Can be separated). As a result, usability is improved.

  Further, in this embodiment, the latch 50 engages with the front wall portion (vertical portion) 72A of the engaging recess 72 of the striker 70 of the inner drawer 16 only when the protrusion amount of the latch 50 is large, and the protrusion amount of the latch 50 The latch 50 engages with the front wall portion (inclined portion) 72B of the engaging recess 72 when the angle becomes smaller. For this reason, the engagement amount between the latch 50 and the striker 70 of the inner drawer 16 is forced by reducing the protrusion amount of the latch 50 and engaging the latch 50 with the front wall portion (inclined portion) 72B of the engaging recess 72. A semi-interlocking section that can be released automatically can be formed. As a result, the semi-interlocking section can be formed with a simple configuration.

  Further, in this embodiment, as shown in FIG. 7, the coil spring 52 biases the latch 50 in the direction in which the latch 50 is pressed against the latch cam surface 40 (the direction of arrow C in FIG. 7). Therefore, a shortage of the protrusion amount of the latch 50 can be prevented. As a result, the latch 50 can be reliably engaged with the striker 70 of the inner drawer 16.

  Further, in the present embodiment, as shown in FIG. 8, the coil spring 62 biases the hook 60 against the hook cam surface 46. For this reason, lack of protrusion amount of the hook 60 can be prevented. As a result, the hook 60 can be reliably engaged with the back plate 14B of the main drawer 14.

  In the present embodiment, as shown in FIG. 5, when the lock 80 is manually moved forward (in the direction of arrow A in FIG. 5), the hook 60 is coiled by the inclined surface 82 provided on the side surface 80A of the lock 80. The spring 62 moves upward (in the direction of arrow C in FIG. 5) against the urging force of the spring 62 and is locked. For this reason, by locking the hook 60 in the upper position, the slider 36 can be prevented from interlocking with the main drawer 14 when the main drawer 14 moves in the drawer direction (arrow A direction in FIG. 1). As a result, it is possible to prevent the inner drawer 16 from interlocking with the main drawer 14.
