DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a main body of a horizontal multi-stage cabinet having a relatively wide frontage; 2, a drawer; In FIGS. 2 to 4, A indicates a lock device, and a vertical groove 6 provided in a part of the convex portion 5 of the main body front reinforcing plate 4 having a U-shaped cross section inside the cabinet main body 1 has an outer cross section. A U-shaped key plate 7 is vertically movably fitted. On the other hand, a rocking plate 9 is provided in an engagement hole formed in an appropriate portion of a support plate 8 provided on the lower surface of the top plate 1 ′ of the cabinet body 1. An engaging projection 9 ′ protruding from the rear edge of the key plate 7 is engaged and supported so as to be swingable, and a swing plate protruding piece 25 at the end of the swing plate 9 is engaged with an upper end of the key plate 7. The key plate 7 is supported by engaging with the hole 10 (see FIG. 2), and the dead bolt 14 is provided at an appropriate position substantially on the right or left side of the frontage of the support plate 8 so as to be able to ascend and descend. . Bend 18 at the upper end of dead bolt 14
Are engaged with a projection 20 provided at an end of the operating tool 19. The operating tool 19 rotates about a mounting tool 21 attached to an operating tool mounting plate 17 fixed to the support plate 8 via a mounting portion 24, and a connecting plate 22 provided at the other end of the operating tool 19.
Are supported by the fixture 21. This connecting plate 22
A shaft 23 is provided at the other end of the swing plate 9, and an end of the shaft 23 is engaged in a swing plate cutout portion 26 formed in a part of the swing plate 9. Since the rocking plate projection 25 provided at the end of the rocking plate 9 is loosely fitted into the engagement hole 10 of the key plate 7, when the lock 16 is turned and locked, the bent portion 18 of the dead bolt 14 is bent. Pushes up the projection 20 of the operating tool 19. A connecting plate 22 connected to the connecting plate 22 is similarly pushed up and rotated via a mounting member 21 fixed by a mounting portion 24, and a shaft 23 provided at an end of the connecting plate 22 moves the swing plate 9. The key plate 7 moves upward as a result. Due to the upward movement of the key plate 7, the outwardly bent piece 12a of the rotary plate 12 engaged with the engagement hole 7a formed in the key plate 7 moves upward. Due to this upward movement, the bent piece 12b is lowered while rotating about the projecting shaft 11 provided on the rotating plate 12. For this reason, as shown in FIG. 3, the bent piece 12b is lowered to the lower position as shown by the two-dot chain line. Therefore, when trying to pull out the drawer 2, the stopper 13 collides with the bent piece 12b, and each drawer 2 can be pulled out. There will be no locked state. Further, a drawer front back plate 27 is provided on the upper back side of the drawer front plate 15 so as to be linked to the dead bolt 14. A safety device is provided at an upper portion between the drawer front plate 15 and the drawer front back plate 27 (which is changed depending on a position where the dead bolt 14 is attached). If the drawer is not completely closed, this safety device is interposed between the drawer front plate 15 and the drawer front back plate 27 as shown in FIG. It is urged to a vertical position as shown by. Therefore, even if the lock 16 attempts to raise the dead bolt 14, it cannot be raised. However, when the drawer is completely housed and closed in the cabinet body 1, the projection 30 attached to the operation plate 29 against the spring 28 collides with the upper end surface of the cabinet body 1 and tilts as shown by a solid line, and the lock 16 As a result, the deadbolt 14 can be raised, so that the lock can be performed. Needless to say, the drawer front back plate 27 is provided with a hole into which the projection 30 is inserted. It is needless to say that the operating plate 29 may not have a bent portion as shown in the figure as long as the operating plate 29 can be engaged with and disengaged from the dead bolt 14.

Next, the operation will be described. The rotating plate 1 is located at the position corresponding to each drawer 2 of the convex portion 5 of the main body front reinforcing plate 4.
2 is pivotally mounted on the protruding shaft 11 so as to be rotatable, and its outwardly bent piece 12a is engaged with a square engaging hole 7a formed at a corresponding position of the key plate 7. When the rocking plate 9 is located at the lower portion by the unlocking operation, the key plate 7 is lowered via the rocking plate 9, and accordingly, the outwardly bent piece 12 a of the rotating plate 12 is moved. Since it is lowered, it is rotated around the protruding shaft 11 and the inwardly bent piece 12b at the rear end is at the raised position, and therefore, the stopper 13 fixed to the side surface of the drawer 2
Does not collide with the inwardly bent piece 12b, and the drawer 2 can be pulled out freely. On the other hand, when the rocking plate 9 is moved upward by the locking operation to bring the rocking plate 9 to the upper position, the key plate 7 is raised, and accordingly, the outwardly bent piece 12a of the rotary plate 12 is moved. Then, the inwardly bent piece 12b at the rear end is raised about the protruding shaft 11 so as to collide with the stopper 13, so that the drawer 2 cannot be pulled out. Although the key plate 7 is urged downward by its own weight, it may be urged downward by a spring if necessary. As described above, when the lock 16 attached to the upper drawer front plate 15 and the lock device A of the cabinet body 1 are in the locked and unlocked state, the stoppers 13 of the drawers 2. Since it is disengaged from the inwardly bent piece 12b at the rear end of the moving plate 12,
A latch (not shown) can be released with fingers inserted into the pull opening 3 of each drawer 2 to pull out or not to pull out. When the drawer is further imperfectly inserted into the cabinet body 1, the operating plate 29 of the safety device does not run away from the dead bolt 14, so that the dead bolt 14 does not rise, so that the bent portion 18
Does not collide with the end of the cabinet body 1 and is not damaged.

[0008]

According to the present invention, the following effects can be obtained based on the above configuration. (1) Because the safety device is provided, unless the drawer is completely closed to the cabinet body, it cannot be locked and the deadbolt does not rise, so the bent part of the deadbolt may damage the cabinet body side by mistake. Absent. (2) If you forget to insert the key into the drawer and try to lock it as it is, the deadbolt will not rise, so there is no worry about being locked.
