Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a double drawer prevention mechanism for a storage device that accommodates a plurality of drawers.

In storage devices such as cabinets with multiple stacked drawers for storing documents, etc., and casings with stacked stacks of multiple electronic devices, 1
If one drawer or a drawer for electronic devices is pulled out and another drawer is pulled out, the center of gravity of the entire storage device will be moved to the front of the storage device, and there is a risk that the storage device will fall over.

Conventionally, in order to avoid this type of danger, a caution label prohibiting pulling out two or more drawers has been displayed to call the user's attention and prevent the danger. However, it is impossible to completely prevent two or more drawers from being pulled out only by calling attention to them using caution labels, and there is a limit to the danger prevention.

SUMMARY OF THE INVENTION The object of the present invention is to eliminate the above-mentioned drawbacks and provide a double-drawer prevention mechanism that prevents other drawers from being pulled out when one drawer is pulled out.

The double drawer prevention mechanism of the present invention is provided in a storage device that accommodates a plurality of drawers, and is provided corresponding to any two or more drawers among the plurality of drawers, and is provided in a case of the storage device. a drive member that is rotatably held by the drive member and takes a pressed position when the drawer is in the storage position and takes a release position when the drawer is in the drawer position; a connecting member that assumes the return position when all of the drive members are in the pressed position and assumes the drive position by the rotational movement of the drive member when at least one of the drive members is in the release position; The connecting member is provided corresponding to two or more drawer parts, is rotatably held in the housing of the storage device, has a first claw part at one end thereof, and connects the other end with the connecting member. a lever member that assumes a separated position when in the return position and assumes an engaged position when the connecting member is in a drive position;
said arbitrary two or more claws, each having a second claw that is provided corresponding to said screw member, is attached to said arbitrary two or more drawer parts, and engages with said first claw of said screw member; The second claw portion engages with the first claw portion of the screw member only when the corresponding drawer portion of the plurality of drawer portions is in the storage position and the screw member is in the engagement position. and a hooking member.

Hereinafter, the present invention will be explained in detail by way of examples with reference to the drawings.

Referring to FIG. 1, a storage device 10 employing an embodiment of the present invention houses drawers 1 and 2. As shown in FIG. In the figure, reference numeral 1' indicates when the drawer portion 1 is in the drawer position.

Fig. 2 is a partially cutaway side view of the main parts of an embodiment of the present invention, particularly showing the hooking member, the lever member, the driving member, and the connecting member, and Fig. 2a shows the drawer part. When 1 and 2 are in the storage position,
Figure b shows the drawer part 1 being pulled out and in the pulled out position 1'.

In the figure, drive members 15 and 15' are provided corresponding to drawer parts 1 and 2, respectively, and shafts 23 and 2 are fixed to the housing of storage device 10.
3' and is rotatably held around spring 1.
7 and 17' are always applying clockwise rotational force, but when the drawer part 1 or 2 is in the retracted position, its upper end is pressed and the spring 17 or 17' is stretched and reversed. Rotate clockwise to take the pressed position, and then pull out drawer part 1 or 2.
When it is in the drawn-out position, the upper end is released from the pressed state and is rotated clockwise by the spring 17 or 17' to take the released position.

The connecting member 16 is connected to the driving members 15 and 1 described above.
5' is a member that operates by being driven by the spring 18.
Therefore, when all the drive members 15 and 15' are in the pressed position, they are pulled down and the protrusions 19 and 19' contact the left ends of the drive members 15 and 15'. However, when the drive member 15 or 15' assumes the release position, the force of the spring 17 or 17' is greater than the force of the spring 18, so that its left end causes the drive member 15 or 15' to move through the protrusion 19 or 19'. It takes a drive position where it is pushed up and stopped by the stop member 20.

The lever members 12 and 12' are provided corresponding to the drawer parts 1 and 2, and are held so as to be able to swing around shafts 22 and 22' fixed to the housing of the storage device 10. , its left end is rotatably connected to shafts 24, 24' fixed to the connecting member 16. Therefore, when the connecting member 16 is in the return position, it assumes a separated position in which the right end claws 14 and 14' are lifted upward, but when the connecting member 16 assumes the drive position, the claws 14 and 14' are lifted upward. It assumes the engaged position pulled downward.

The hooking members 11 and 11' are provided corresponding to the lever members 12 and 12', respectively, and the hook portions 14
and 14', and are attached to the drawer parts 1 and 2, respectively, and when either the drawer part 1 or 2 is in the storage position, the corresponding lever member 12 or 12'
The claw portion 14 or 14' of the holder is configured to engage with the claw portion 13 or 13'.

Next, the operation of the double drawer prevention mechanism of the present invention will be explained using an example.

In FIG. 2a, since the drawer parts 1 and 2 are both in the storage position, the driving members 15 and 15' are both in the pressing position, so that the connecting member 16 is in the return position and the lever members 12 and 12' are in the separating position. I'm taking it. Therefore, the lever members 12 and 12'
The claws 14 and 14' and the hooking members 11 and 1
The claws 13 and 13' of 1' do not engage,
The drawer part 1 or 2 can be freely drawn out.

When the drawer part 1 is pulled out and takes the drawer position 1' as shown in FIG. 2b, the driving member 15 is released from the pressed state by the rear end of the drawer part 1.
The force of the spring 17 causes rotational movement in the clockwise direction.

Since the force of the spring 17 that applies rotational force to the drive member 15 is greater than the force of the spring 18 that pulls down the connection member 16, the connection member 16 is moved through the protrusion 19 by the rotational movement of the drive member 15 described above. It is stopped by a stop member 20 lifted upward and fixed to the housing of the storage device 10 to assume the drive position, and thereby the drive member 15 also stops its rotational movement and assumes the release position.

When the connecting member 16 assumes the drive position as described above,
The lever members 12 and 12' whose left ends are connected to the connecting member 16 are rotated clockwise around shafts 22 and 22' fixed to the housing of the storage device 10, Parts 14 and 1
4' assumes an engagement position where it engages with the claws 13 and 13' of the hooking members 11 and 11', but the drawer part 1
has already been pulled out and is in the drawer position 1', the claw part 13 of the hooking member 11 and the claw part 14 of the lever member 12 are not engaged, and the hooking member of the drawer part 2 in the storage position is not engaged. Claw part 13' of 11' and screw member 1
Only the claw portion 14' of the pull-out portion 2' is engaged with the claw portion 14' of the pull-out portion 2'.
The withdrawal operation is blocked.

When the drawer part 1 is retracted, the driving member 15,
Since the connecting member 16 and the lever members 12, 12' respectively assume the pressed position, the return position and the separated position shown in FIG. 2a, either of the drawer portions can be pulled out.

FIG. 3 is an exploded perspective view of the locking mechanism portion of the above-described embodiment of the present invention shown in FIGS. An example is shown.

In the figure, a first connecting member 31 having a connecting elongated hole 35 is coupled to the lock 30, and the connecting member 31 rotates a shaft 38 fixed to the housing of the storage device 10 through the connecting elongated hole 35. It is connected to a protrusion 36 at the tip of the second connecting member 32 that can perform a pivoting movement. Therefore, when the lock 30 is turned clockwise for locking and assumes the locked position, the connecting member 32 lifts its rear end upward via the connecting member 31 to assume the fixed position, and the lock 30
is turned counterclockwise to unlock and assumes the unlocked position, then lowers its rear end and assumes the release position.

There is an elongated hole 39 at the rear end of the connecting member 32, which engages with a protrusion 40 at the upper end of the connecting member 16, and when the connecting member 32 is in the fixed position, the protrusion 40 is formed at the lower edge of the elongated hole 39. Push up the connecting member 16
is fixed in the driving position, but when the connecting member 32 is in the detached position, the connecting member 16 returns to the return position and can freely move within the range of the oblong hole 39.

Therefore, when the drawers 1 and 2 are in the storage position as shown in FIG. 32 to the driving position, and accordingly the lever members 12 and 1
2' is in the engaged position, and its claws 14 and 14' are engaged with the claws 13 and 1 of the locking members 11 and 11'.
3' to prevent the drawers 1 and 2 from being pulled out.

In the above state, when the key 34 is turned in the opposite direction to the locking direction to take the unlocked position, the connecting member 3
1 operates in the opposite direction to the above-described operation, the rear end of the second connecting member 32 moves downward, and following this, the connecting member 16 moves downward by the force of the spring 18 and returns to the return position. This releases the connection member 16 from the connection member 32, allowing the connection member 16 to move freely within the elongated hole 39 of the connection member 32. Prevention can be carried out. Therefore, by adopting the invention shown in this embodiment, it is possible to obtain a mechanism that has a simple structure, has a locking function, and can prevent double drawers.

Although the above embodiments are all for storage devices with two drawers, the same applies to any two or more storage devices with three or more drawers.

As explained in detail above, according to the present invention, when one of the plurality of drawers is drawn out, the other drawers are prevented from being drawn out, so that two or more drawers are Not only does it have the effect of preventing the risk of the storage device falling over when the storage device is pulled out, but by adding a lock and a connecting member to it, it has a locking function and prevents the storage device from falling over due to double drawer prevention. effective.
