Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an unlocking mechanism in an emergency in a locker or the like in which a plurality of storages are provided in one underframe.

[Conventional technology]

A locker used for storing valuables has a large number of storages, each of which has a door and a lock mechanism.

If such a lock mechanism is an electric lock, the lock cannot be opened and closed in the event of a power failure. Also, in an emergency, it becomes necessary to open these doors.

In this case, conventionally, the emergency unlocking is performed by operating each door.

[Problems to be solved by the device]

However, when the number of doors is large, there is a drawback that it takes too much time to perform the emergency unlocking for each door in an emergency.

An object of the present invention is to provide an emergency unlocking mechanism capable of unlocking all doors in a vertical or horizontal row by one key operation.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention is a plurality of locking devices provided at desired intervals on an underframe, and a latching solenoid having a plunger as a moving member and a moving member advanced and retracted by the latching solenoid. In the emergency unlocking mechanism that unlocks all of the things that are unlocked and locked by means of the above, an engaging portion is formed on the moving member, one side is substantially parallel to the moving direction of the moving member, and the other side is the moving direction. A rail for advancing and retracting along the intersecting V-shaped guide is provided, and an engaged portion capable of engaging with the engaging portion in both directions of locking and unlocking is provided on the rail, and a tongue for advancing and retracting the rail is provided. It is characterized by having a cylinder lock.

[Action]

The operation of the present invention will be described. When the cylinder lock for emergency unlocking is operated, the tongue of the cylinder lock moves the rail along the V-shaped guide. The engaged portion provided on the rail was initially distant from the moving member of the locking device, but when the rail moves along the V-shaped guide, it approaches the moving member and engages with the engaging portion, and eventually. Move the moving member to the unlock position. By moving the moving member of each locking device, each door is unlocked at the same time. After the emergency check,
When the cylinder lock is locked, the tongue of the cylinder lock moves the rail in the opposite direction. The engaged portion of the rail engages with the engaging portion formed on the moving member of each lock device,
Each moving member is moved in the locking direction along with the movement of the rail, and when the movement is completed, the moving member is separated from the moving member along the V-shaped guide and disengaged.

〔Example〕

FIG. 1 (a) is a front view showing an example of the emergency unlocking mechanism,
(B) is the enlarged side view. In the figure, a rail 1 is formed in a U-shape, and a long hole 3 for mounting is projected on a surface corresponding to a bottom surface and is mounted on a rail mounting frame 18 by a bolt 2. Also, the part corresponding to the U-shaped side that is on the lower side of the figure is bent and the underframe is
The rail 1 is fitted in a guide groove 19 provided in the rail 17 so that the rail 1 can be stably supported. Rail mounting frame 18 is an underframe
It is fixed to 17 by welding.

A bracket 6'is erected on the underframe 17 so as to face the rail, and a cylinder lock 6 for emergency unlocking is provided on the bracket 6 '.
Is installed. The cylinder lock 6 has a tongue 5 which is rotated by a key operation. A pin 7 is erected on the tongue 5, and the pin 7 is fitted in a pin hole 4 which is a long hole formed in the rail 1. .

The rail 1 is provided with as many protruding engaged parts 8 as the number of the lock devices 20, and the number of the lock devices 20 is provided, and the engaging parts 8 formed at the tip of the moving member 9 of each lock device 20. The mating portion 9'can be engaged from one direction. The moving member 9 is a suction element of the solenoid 10 in this example.

With the above configuration, when the cylinder lock 6 for emergency unlocking is operated by a key, the tongue 5 rotates, and accordingly, the pin 7 moves along the pin hole 4 and the rail 1 moves to the right in FIG. 1 (a). Each engaged part 8 moves each engaged part 9'to the solenoid 10
Move it in the direction to push it in. FIG. 2 is a diagram showing the state at this time.

Next, regarding the lock device, in this example, the lock device is composed of an electric lock using a solenoid. The structure of this lock device will be described with reference to FIGS. 3 (a) and 3 (b). In the figure, the door 21 is locked with a slight gap between it and the underframe 17. A hook 15 is fixedly attached to the door 21, and is fitted into the concave groove 13a of the latch 13 when the door is closed, and the latch 13 is rotated to separate the hook 15 from the concave groove 13a when the door is opened. The latch 13 is rotatably supported by a latch shaft 13 'provided on a frame 16 fixed to an underframe 17, and is biased in a door opening direction by a latch spring 14. A latch stopper 11 is provided to prevent the closed and locked latch from rotating in the opening direction. The latch stopper 11 has a rod shape, and a step portion 11 'is formed near the tip of the latch stopper 11 so that the latch 13 is fitted therein and its rotation is restricted. The latch stopper 11 is biased toward the rear end by the stopper spring 12, and the rear end portion is in contact with the moving member 9 which is the attractor of the solenoid 10. Solenoid 10 is a frame
It is fixed to the screw 16 by means of screws 10 ', and when excited, the moving member 9 is attracted against the spring, and when demagnetized, the moving member 9 is returned to its original position by the spring.

The door is opened and closed as follows. When unlocking is supported, the solenoid 10 is excited, the moving member 9 is pulled in, and the latch stopper 11 is set in a retractable state. However, since the step portion of the latch 13 is fitted in the step portion 11 'at the tip, the latch stopper 11 cannot be retracted, and the door is apparently closed.

There is a slight gap between the door 21 and the underframe 17, and when the door 21 is pushed toward the underframe by this amount, the latch 13 disengages from the step 11 ', the latch stopper 11 retracts, and the latch 13 rotates. It will be possible.
When the force applied to the door 21 is removed, the latch 13 rotates and the door is opened.

Next, in the case of an emergency, when the tongue 5 of the cylinder lock 6 for emergency unlocking is rotated by the unlocking operation as described above, the rail 1 moves to the position shown in FIG. 9 is moved to the unlocking side. Then, push and release each door to open it with one touch.

When the inspection work in an emergency is completed and the door is closed and locked, first, with the door opened, operate the above-mentioned cylinder lock to lock the tongue 5 to the position shown in FIG. 1 (a). , Return each moving member to the locking side. The latch stopper 11 is pushed by the moving member 9 and moves against the stopper spring 12 so that the tip end is in pressure contact with the latch 13. After that, when each door is closed, the hook 15 fits into the groove 13a of the latch 13 and the latch 1
Rotate 3 against latch spring 14. When the door 21 is pushed so that it abuts the underframe 17, the latch stopper 11 advances and the recessed groove
It enters into 13a and returns to the position shown in Fig. 3 (a). When the force pushing the door 21 is removed, the latch 13 fits into the stepped portion 11 ', and its rotation is restricted, and the locked state is restored.

Although both the engaged portion 8 and the engaging portion 9'are formed as protrusions, it suffices that the moving member 9 can be moved to the locking position and the unlocking position by the movement of the rail 1, and therefore one of them is a protrusion. It does not change even if the other is a recess.

If there is no step 11 'of the latch stopper 11, the latch stopper 11 and the moving member 9 may be the same member, in which case all the doors can be opened at the same time when the cylinder lock for emergency unlocking is unlocked. It will be.

Further, when the latch stopper 11 is formed with the step portion 11 'and is integrated with the moving member 9, the engaged portion 8 on the rail side can slide by the stroke of the moving member 9 and is biased by the spring. With this configuration, the same operation as in the example of FIG. 1 can be performed.

By the way, in a locker used by an unspecified number of people, a latching solenoid may be used instead of the solenoid 10 in the locking device of FIG. The latching solenoid latches the plunger serving as the moving member 9 at both the sucked position and the projected position. Therefore, if the solenoid is demagnetized, the moving member 9
You cannot return to the original position. When such a solenoid is used, it cannot be locked unless the locking operation is performed, and more reliable locking is possible.

However, in that case, the emergency unlocking mechanism of FIG. 1 cannot be used. Even if the engaged portion 8 separates from the engaging portion 9 ', the moving member 9
Is latched and cannot return to its original position.

4 and 5 are views showing an embodiment of the present invention, in which an engaged member drives the engaging member in both directions of unlocking and locking.

The configuration of this emergency unlocking mechanism will be described focusing on the differences from the example of FIG. 10 'is a latching solenoid,
The plunger is the moving member 9. An engaging portion 9'is formed on the moving member 9. A V-shaped guide 31 is formed in the rail 1 as a long hole, and a mounting frame (first
(Refer to reference numeral 18 in the figure). One side of the V-shaped guide 31 is a groove substantially parallel to the advancing / retreating direction of the moving member 9, and the other side is an oblique groove provided in a direction intersecting the advancing / retreating direction.
Therefore, the rail 1 moves substantially parallel to the advancing / retreating direction of the moving member 9 in the parallel groove, and moves in the advancing / retreating direction while coming into contact with / separating from the engaging portion 9'in the oblique groove. The engaged portion 81 provided on the rail 1 has two engaging surfaces 81a and 81b so that it can engage with the engaging portion 9'from either the left or the right. In the state shown in FIG. 4, since the emergency unlocking mechanism is not in operation, it can be locked and unlocked as an electric lock having the latching solenoid 10 '.

The operation of the emergency unlocking mechanism will be described focusing on the differences. To unlock in an emergency, the cylinder lock 6 is operated by a key to rotate the tongue 5 to the state shown in FIGS. 4 to 5. The rail 1 moves along the oblique groove of the V-shaped guide 31, and the engagement surface 81a of the engaged portion 81 comes close to and abuts the engagement portion 9 '. Further, it moves along the parallel grooves of the V-shaped guide 31, and the moving member 9 is held by the latching solenoid 10 ', resulting in the state shown in FIG. This is the same state as in FIG. 2, and each door can be opened as described above.

When the emergency check is completed, the tongue 5 of the cylinder lock 6 is rotated to return the rail 1 to the state shown in FIG. At this time, the engaging surface 81b of the engaged portion 81 contacts the engaging portion 9'and returns to the position shown in FIG. When the return is completed, the engaged portion 81 is separated from the engaging portion 9'and the operation as a normal electric lock becomes possible. How to close each door is the same as that of the embodiment shown in FIG.

In this embodiment, the engaging portion 9'is forcibly returned to the locking position, and even if the moving member 9 does not return due to being caught or the like, reliable locking can be achieved. Therefore, it is not limited to the case of the latching solenoid, but can be used in a wide range.

[Effect of device]

As described above, the present invention can open doors in a vertical or horizontal row by a single emergency unlocking operation, and can perform inspection work in an emergency in a short time.Each door has an emergency unlocking mechanism. Compared to having it, it has the special effect of being able to reduce costs.

Further, since the engaging portion is configured to engage with the engaged portion both when locked and unlocked, it is effective not only when the moving member is latched, but also when the engaging portion surely returns in the locking direction. Therefore, the locking failure can be prevented.
