Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a locking mechanism provided in a drawer for a wardrobe, a wardrobe, a costume dance, etc.

<Prior art and its problems> When a simple safe function is provided in a drawer for a wardrobe, a sorting drawer, a costume dance, etc., a lock operation part (free insertion slot) is usually provided on the front panel of the drawer. . For this reason, it is not very desirable from the viewpoint of theft prevention, as it is easy to see at a glance which drawer is storing valuables, etc., and it is also easy to unlock the lock. Furthermore, since the operating part of the lock is exposed on the surface, it is not suitable from a design point of view.

<Means for Solving the Problems> The present invention has been made in view of the above-mentioned problems, and includes a lock having an operation part on the back of the front plate of one of the left and right drawers, and the front plate of the drawer. is formed to be slidable, and a control member interposed between a pair of drawers is interlocked with the other drawer, and when both drawers are pushed in, the slidable front plate When the sliding movement is blocked by the front plate of the drawer and the other drawer is pulled out, the sliding movement is similarly kept blocked by the control member pulled out in conjunction with the control member, and when the other drawer is pushed in, When the blocking by the control member is released, the operation part of the lock provided on the one drawer can be opened.

<Function> That is, when both drawers are pushed in, the front plate of one drawer hides the operating part of the lock, and the front plate of the other drawer prevents the front plate of one drawer from sliding. Ru. Therefore, the direct operation section cannot be disclosed. Furthermore, even when the other drawer is pulled out, the sliding movement of the front plate of one drawer is still prevented by the control member interlocked with the other drawer, and the operating section is similarly hidden. On the other hand, when the other drawer is pushed in, the control member is also pushed in in conjunction with this, and the inhibition of sliding movement by this control member is released. As a result, the front plate of one of the drawers can be slid, so that the operating section provided on the back of the front plate of this drawer can be opened.

That is, the drawer locking mechanism of the present invention allows the front plate to slide by once pulling out the other drawer and then pushing it in again, thus providing a so-called double locking mechanism.

<Example) The locking mechanism of the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a perspective view of a chest of drawers, and a pair of drawers 1.2 are disposed on the left and right sides of the chest of drawers.

Furthermore, a control member 3 is interposed between the drawers 1 and 2. FIG. 2 is a schematic plan view for explaining the drawer 1.2 and the control member 3.

Drawer 1 is on the front 11. Rear surface 12. The side surfaces 13 and the bottom surface 14 form a box-shaped base, and a front plate 16 is attached to the front surface 11 via a movable member 15. On the other hand, the drawer 2 forms a box-shaped base body as described above, and a front plate 21 is attached to the front surface thereof. Furthermore, the control member 3 can be, for example, a drawer l.

Like 2, it consists of a small box-like thing with a storage box.
Its front surface 31 is disposed within the back surface of the front plate 21 of the drawer 2. The drawer 1, the drawer 2, and the control member 3 are each disposed within a chest of drawer body formed by the side panels 4, 4, the back panel 5, and a top plate and a base plate (not shown). The drawer l and the control member 3 are separated by a fixed middle crosspiece 6 of the main body of the apparatus. A stopper pin PI is attached to this fixing middle crosspiece 6, and by fitting this stopper pin P into the slide groove P2 of the control member 3, the pull-out length of the control member 3, which will be described later, is controlled.

A stopper pin P3 is also attached to the drawer 2 side of the control member 3, and this stopper pin P3 is fitted into a slide groove P4 of the drawer 2 to control the length of drawer 2.

On the other hand, the drawer 2 is provided with a magnetic catch MC, and the control member 3 is provided with a corresponding magnetic plate MP, so that when the drawer 2 is pulled out by magnetic attraction, the control member 3 is pulled out in conjunction with the magnetic catch MC. It has become. In order to facilitate this interlocking, a push-out arm PA is provided at the rear of the control member 3.

In this example, a cylinder lock 7 is attached to the drawer l to provide a so-called safe unit. The operating section 71 is arranged on the back of the front plate 16.

Further, in order to slide the front plate 16 of the drawer l in the direction of the drawer 2, a movable member 15 is provided between the front plate 11 and the front plate 16.

As shown in FIG. 3, which is a cross-sectional view taken along the line XX in FIG. It is meant to slide.

Next, we will explain how the operating part of the lock in this lock mechanism is concealed and disclosed.

FIG. 4 is a perspective view showing the drawer 1.2 in the pushed-in state.

Normally, the lock 7 of the drawer is locked, and the drawer cannot be pulled out, which is a so-called locked state. Also in this case the drawer
The front plate 16 of the drawer 2 and the front plate 21 of the drawer 2 are on the same surface, and each side end surface 16a, 21a is in an opposing state. Therefore, the front plate 16 is prevented from sliding by the front plate 21.

In this state, the other drawer 2 is pulled out. Then, as described above, the magnetic plate MP is attracted by the magnetic force of the magnetic catch MC, and the control member 3 is similarly pulled out in conjunction with it (see FIG. 5). If the drawer 2 is further pulled out, the pull-out length of the control member 3 is limited by the stopper pin PI, and the interlocking movement with the drawer 2 is stopped, as shown in FIG. Further, if the drawer 2 itself is pulled out as it is, the length of the drawer is limited by the stopper bin P3.

As a result, a gap H is formed between the front plate 21 of the drawer 2 and the front surface 31 of the control member 3. In this state, the front plate 16 of the drawer l has its side end surface 16a aligned with the side surface 32 of the control member 3.
comes into contact with. Therefore, the sliding movement remains blocked in the same manner as described above. Next, as shown in FIGS. 7 and 8, when the drawer 2 is pushed in, the attraction between the magnetic catch MC and the magnetic plate MP is restored, and the front surface 31 is spaced from the front plate 21 at a predetermined distance (slightly narrower than H above). (distance) is maintained. Therefore, as shown in FIG. 9, even if the control member 3 is pushed back into its original state, the front plate 16 of one of the drawers 1 is within the predetermined distance formed by the front plate 21 of the drawer 2 and the front surface 3I of the control member 3. It becomes possible to slide (in the direction of the solid line arrow in the figure). When the front plate 16 is slid to the dotted line state in the figure, the operation part 71 of the cylinder lock 7 arranged on the back of the front plate 16 is disclosed as shown in FIGS. 10 and 11. Insert the key 8 into the insertion slot to unlock the cylinder lock 7. This unlocks the locked state and allows the drawer 1 to be pulled out.

On the other hand, in order to lock the drawer 1, it is sufficient to perform the operation opposite to the above. In other words, first! All you have to do is lock the cylinder lock 7 with the I8, remove the key 8, slide the front plate 16 of one drawer in the opposite direction (in the direction of the dotted arrow in FIG. 9), and then push in the other drawer 2.

<Effects of the Invention> As explained above, the drawer locking mechanism of the present invention does not directly expose the operation part of the cylinder lock.

It is extremely suitable in terms of theft prevention and aesthetics, and also has a high safe function because the lock mechanism itself can only be released by double operation.
