【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an exploded perspective view showing a cabinet C according to an embodiment of the present invention in a partial cross section. The cabinet is provided with a plurality of drawers D (only two are shown in FIG. 1) arranged vertically. An opening 41 for repair and inspection is provided on the top plate of the main body W of the cabinet, and an upper plate P for covering the opening 41 is placed on the top plate.

The drawer C lock device 3 is built in the cabinet C. The lock device 3 includes a first guide rail 1, a second guide rail 2, a first slide bar 31, and a second slide bar 32.

The first and second guide rails 1 and 2 are mold members having a C-shaped cross section as shown in FIG. 2, and the first guide rail 1 is arranged on the inner surface 4 of the top plate of the cabinet body W in the front-back direction. The second guide rail 2 is extended and fixed, and extends vertically in a direction orthogonal to the first guide rail 1 and is fixed to the inner surface of the back plate.

The first slide bar 31 is housed in the first guide rail 1 and is slidable on the rail in the length direction thereof, and the operation member 35 (FIG. 5) is attached. The second slide bar 32 has a roller S fitted in the second guide rail 2 at a rear surface thereof, and is movable on the rail 2 in the longitudinal direction thereof. On the front surface of the slide bar 32, the bolt 6 which is the first engaging element corresponds to the parallel spacing of the metal fittings 7 and 7 (FIG. 3) which are the second engaging elements fixed to the rear side of the drawers D and D. It is projected at intervals. The bolt 6 has a head with a diameter larger than its outer diameter, and the metal fitting 7 has a hook portion 71 on which the head of the bolt 6 can be fitted under frictional engagement. Adjacent ends of the slide bars 31 and 32 are connected by a metal fitting 34.

The guide rails 1 and 2 are provided with screw holes 10 and 20 for attaching the rails to the inner surface of the furniture main body W.

As shown in FIG. 2, the metal fitting 34 is L-shaped so as not to come into contact with the upper edge of the back plate of the uppermost drawer D, and both ends of the L-shape are adjacent ends of the slide bars 31 and 32. It is pivotally attached by a pin 36 to a lug 33 fixed to the part.

The connection of the adjacent ends of the slide bars 31, 32 may be in the form of a flexible strip 9 such as a leaf spring, as shown in FIG. In this case, both ends of the strip 9 are connected to the ends of the slide bars 31 and 32, respectively, and when the slide bar 31 slides, the strip 9 moves smoothly. A member 8 for easily elastically deforming the strip 9 is arranged on the upper end of the guide rail 2. The member 8 can be in the form of a roller-type, fixed-type smooth member as shown.

In the cabinet C configured as described above, in order to lock the drawer D, the uppermost drawer is pulled out to the front of the cabinet, and the hand is inserted into the inside of the main body W through the opening in the upper part of the main body W. It is advisable to pull the operating member 35 toward you.

By the above operation, the slide bar 31 slides forward on the first guide rail 1, and accordingly, the slide bar 32 slides upward on the second guide rail via the metal fitting 34 to slide. The head of the bolt 6 of the bar 32 and the metal fitting 7 on the rear surface of the drawer D are engaged with each other. That is, the drawers D and D are locked. If the uppermost drawer is pushed back into the main body W, the locking device 3 in the locked state cannot be seen from the outside.

To unlock the drawer, the operation member 35 may be pushed back toward the front side.

When it is necessary to stabilize the locked state of the lock device 3, it is preferable to provide the guide rail 1 with a stopper such as a latch for restraining the slide bar 31.

FIG. 6 is a perspective view showing the outline of a cabinet C ′ according to another embodiment. In this modified embodiment, the drawers are arranged side by side, and the main structure is substantially the same as that of the above-described embodiment except that the lock device 3 〃 adopts the corresponding structure. is there. In the embodiment of FIG. 6, an opening 60 extending in a predetermined direction is provided on the side surface of the drawer D on the side facing the first guide rail 1 to allow the operation member 35 to move back and forth.

In the example of FIG. 6, the lock device 3 ″ can be locked by opening the drawer D ″ and pulling the operating member 35 forward through the opening formed thereby and the opening 60. On the contrary, if you push it in, it will be unlocked.

As described above, in the present invention, the second slide bar 32 functions as a common locking main body for the side drawers D, D. A first slide bar is connected to the slide bar so as to operate the slide bar in a predetermined direction. With this structure, the drawer lock device can be built into the storage furniture as a simple structure. In addition, the lock device can be equipped with little or no modification of the storage furniture.

The first and second guide rails 1 and 2 facilitate the movement of the bars 31 and 32 in a predetermined direction.
