Is opened.

To make the door 31 lockable again,
The cover 14 shown in FIG. 3 is removed, and the push-up piece 62a of the lever 62 is pushed up by hand from below. Thereby, the electric lock 50 returns to the normal state, and the lock can be performed again.

Next, a specific configuration of the manual unlocking unit 60 will be described. FIG. 4 is a side view of the manual unlocking unit 60 in a steady state viewed from the side wall 11 side. FIG.
Is a perspective view of the manual unlocking unit 60 in a steady state as viewed from below. The manual unlocking unit 60 is fixed to an inner plate 11 b of the side wall 11 via a mounting plate 61. A lever 62 is attached to the attachment plate 61 so as to be rotatable up and down around a shaft 62b. However, when no force is received from another member, the lever 62 is balanced so that the push-up piece 62a side is lowered by its own weight. A hook portion 621 facing downward is formed at an end of the lever 62 opposite to the push-up piece 62a. When the door 31 is opened, the stopper plate 331 fixed to the end 33 a of the plunger 33 is fitted to the hook 621.

FIGS. 6A and 6B are views showing a connection structure between the lever 62 and the plunger 33. FIG. 6A is an enlarged view of an end 33b of the plunger 33, and FIG. FIG. The mounting plate 61 has the plunger 3
A slit 611 extending in a direction parallel to the axis of No. 3 is formed. The stopper plate 331 is provided with the plunger 3 so that the protrusion 331a can slide in the slit 611.
It is fixed to 3. When the door 31 of the locker 30 is open, that is, when the end 33a of the plunger 33 protrudes toward the front of the rocker, the protruding piece 331a of the stopper plate 331 fits into the recess 621a of the hook 621. I have. As a result, the lever 62 is fixed in a substantially horizontal direction, and remains stationary even when it receives a force from the outside.

On the other hand, when the door 31 of the rocker 30 is closed and the end 33a of the plunger 33 is pushed in by the door 31, the protruding piece 331a of the stopper plate 331 slides to the left in FIG. 621a. Therefore, the lever 62 is in a free state. At this time, the plunger 33 is connected to the micro switch 3.
Since the terminal 341 of No. 4 is pressed, the sensor point 342 is turned on. Thereby, the control side detects that the door 31 is closed.

Returning to FIGS. 4 and 5, the lever 62
Two connecting holes 62 are provided in a portion outside the mounting plate 61.
c and 62d are formed. These holes 62c, 62d

A protruding push-up portion 622 is formed on a portion of the lever 62 opposite to the hook 621. Above the push-up portion 622, the shaft push-up member 63 is attached. The shaft pushing-up member 63 is formed with two slits 631, 632 extending a predetermined length in the vertical direction. These slits 631 and 632 are loosely tightened by screws 631a and 632a, respectively. As a result, the shaft lifting member 63 is
It is slidable up and down by the length of 1,632.

The shaft lifting member 63 includes a shaft lifting piece 6.
33 are formed. The shaft push-up piece 633 is inserted into the electric lock 50 and is connected to the shaft 52 a of the solenoid 52. Such a shaft push-up member 63 is suspended by a spring 64. Normally, the shaft push-up member 63 is at the lowest position under its own weight and the elastic force of the spring 64, and at this time, the lower end 63 a is in contact with the push-up piece 622 of the lever 62.

The switch piece 13 is formed at an end of the switch lever 65. The lower end of the switch lever 65 is attached rotatably about a shaft 65a.
Further, a stopper piece 651 is formed on the switch lever 65. The stopper piece 651 is formed at a position substantially in contact with the upper end surface of the shaft pushing-up member 63 and is slidably inserted into a slit 612 formed in the mounting plate 61. Thereby, the stopper piece 651 normally suppresses the shaft push-up member 63 from rising. Further, the lever 31 which is in contact with the lower end of the shaft pushing-up member 63 is also prevented from rising on the pushing-up portion 622 side, so that the door 31 is closed and the stopper plate 3 is closed.
Even when the protruding piece 331a of the 31 comes off, it keeps a substantially horizontal state.

The upper part of the switch lever 65 is slidably held in a groove 613a of a holding plate 613 formed on the mounting plate 61. When the switch lever 65 rotates and the stopper piece 651 is
The switch lever 65 is formed to a depth that can sufficiently hold the switch lever 65 even when it is deviated from the position 12. The switch lever 65 having such a configuration is urged toward the mounting plate 61 by a spring 66.

Next, the configuration of the electric lock 50 will be described. FIG. 7 is a perspective view showing a schematic configuration of the electric lock 50.
The solenoid 52 of the electric lock 50 is driven by an electric signal from a control device (not shown) to move the shaft 52a up and down. The shaft 52a can move up and down even when a moderate force is received from the outside. As described above, the shaft lifting member 6 of the manual unlocking unit 60 is attached to the shaft 52a.
The third shaft push-up piece 633 is connected. here,
For example, the shaft push-up piece 633 is connected by contacting the lower portion of the shaft 52a and supporting it from below. Also, the shaft 52
A stopper plate 53 is fixed to a lower end portion of “a”. The stopper plate 53 has a notch 53a.

When the shaft 52a is at the lowermost position, the electric lock 50 has the notch 53a of the stopper plate 53.
Is located lower than the latch 51. For this reason, the latch 51 is in contact with a portion 53b above the notch 53a of the stopper 53. Thereby, the axis 5 of the latch 51
Rotation around 1a is prevented. That is, the door 31 is locked.

On the other hand, an electric signal from the control device is transmitted to the electric lock 5.
When the shaft 52a receives 0, or when a pushing force by the shaft pushing piece 633 is applied to the shaft 52a, the shaft 52a moves up.
At the same time, the notch 53a of the stopper plate 53 is at the same height as the latch 51, as shown in FIG. Accordingly, the latch 51 is released from the restraint and can be rotated around the shaft 51a. That is, the door 31 is unlocked. In this case, the door 31 is automatically opened by being pushed by the plunger 33.

The mounting structure and operation of the latches 41 and 51 are almost the same as those of a normal door, so that detailed description is omitted here. Next, the operation of the manual unlocking unit 60 of the present embodiment will be described.

In the rocker unit 10 of the present embodiment, if a person accidentally enters the larger rocker 30 and the door 31 is closed, the electric lock 50 is locked. In this case, since the LED 13a of the switch piece 13 is lit in the rocker 30 as shown in FIG. 3, the position of the switch piece 13 is known, and the switch 13 can be pressed immediately.

FIG. 9 is a side view of the manual unlocking unit 60 when the switch piece 13 is pressed, as viewed from the side wall 11 side. FIG. 10 is a perspective view of the manual unlocking unit 60 when the switch piece 13 is pressed, as viewed from below. When the switch piece 13 is pressed, as shown in FIG. 10, the switch lever 65 rotates about the shaft 65a, whereby the stopper piece 651 comes off the slit 612.
Therefore, the shaft lifting member 63 is in a free state.

When the door is closed, the stopper plate 3
Since the protruding piece 331a of the switch 31 is disengaged from the hook 621, the lever 62 is completely free when the stopper piece 651 of the switch lever 65 is disengaged from the slit 612. Therefore, the lever 62 rotates counterclockwise in FIG. 9 around the shaft 62b by its own weight. Then, the push-up portion 622 pushes the shaft push-up member 63 upward, and in conjunction with this, the shaft push-up piece 633 moves the solenoid 5.
Push up the second shaft 52a.

When the shaft 52a is pushed up, the electric lock 50 is unlocked as described with reference to FIGS. 7 and 8, and the door 31 is automatically opened by the force of the plunger 33. Therefore, the user can get out of the storage portion 32 of the rocker 30.

After the electric lock 50 is unlocked by the switch member 13, as shown in FIG. 10, most of the slit 612 is closed by the shaft pushing-up member 63, so that the stopper piece 651 of the switch lever 65 is inserted into the slit 612. Do not fit.
In this state, it does not return to the steady state as shown in FIGS. Then, the cover 14 shown in FIG. 3 is removed, and the push-up piece 62a of the lever 62 is manually pushed up.
As a result, the shaft push-up member 63 descends, and the slit 6
12 is released. Since the switch lever 65 is urged toward the mounting plate 61 by the spring 66, when the slit 612 is opened, the stopper piece 651 is easily fitted into the slit 612. Thereby, the manual unlocking unit 60 returns to the steady state.

As described above, in this embodiment, when the switch piece 13 exposed in the storage portion 32 of the rocker 30 is pressed, the lever 62 is rotated by its own weight, and the electric lock 50 is rotated by its own weight.
Is unlocked, so even if a power failure occurs when a person is trapped in the storage section 32, the door can be easily opened manually,
The user can get out of the storage section 32.

Further, since all the functions are incorporated on the mounting plate 61, it can be easily mounted on an existing rocker. Further, in the present embodiment, since the LED 13a operated by the battery is attached to the switch piece 13, the switch piece 1 can be easily placed in the dark storage unit even during a power failure.
3 can be confirmed.

Next, another example of installation of the manual unlocking unit of this embodiment will be described. FIG. 11 is a diagram illustrating another installation example of the manual unlocking unit of the present embodiment. Here, a configuration of a vertically long rocker unit 70 having only one door is shown. In addition,
