23 is a closing door latch, 24 is a control plate, 25 is a bending piece, 26 is a coin locking/disengaging plate, 27 is a coin passage wall, and 28 is a master lock.

The "customer lock 21" is tightened from the inside of the lock casing 20, and the back end 21a of the customer lock 21 is provided with a recess 21b formed in the center of a rotating plate 22, which will be described later. As shown in FIG. 10, the protruding board 21c is inserted into the inner end 21a from the recess 21b, and when the key A is inserted, the tip of the key A presses the inner end of the protruding board 21c, and the protruding board 21c is closed. The outer end of the hole 21b
The outer end of the protruding board 21c presses the adjusting board 26c of the coin locking/retracting plate 26, which will be described later, which is always in contact with the protruding board 21c to rotate the coin locking/retracting plate 26 outward, and then the key A is pressed. When it is pulled out, as shown in FIG. 11, the related removal plate 26 rotates inward and the adjustment board 26c presses the protruding board 21c of the customer lock 21, and the protruding board 21c pushes the supported key. Since there is no holder, the protruding board 21c can be pushed into the rear end 21a of the customer lock 21.

The "rotating plate 22" has the role of a lever that facilitates the driving of the drive shaft 23a of the closing door latch 23, which will be described later, and is formed into a vertically long diamond shape, with the center of the plate serving as a lever for driving the drive shaft 23a of the closing door latch 23.
1, and is rotated left and right by the drive of the customer lock 21. At the upper end of the rotating plate 22, an outwardly facing cylindrical body 22a is installed, through which the drive shaft 23a of the later closing door latch 23 is inserted.

The "control plate 24" controls the drive of the drive shaft 23a, and has a tongue-like shape with a notch 24a formed on the upper side of its tip, and the other end is connected to the drive shaft 23a.
A spring 24b is rotatably mounted on the shaft 3a and rotates upward. Further, the upper side of the tip abuts against a bent piece 25 of a coin passage wall 27, which will be described later.

The "bending piece 25" engages the tip of the control plate 24 and prevents the control plate 24 from rotating upward, and is an opening 27b of the coin passage wall 27, which will be described later.
The upper part is bent.

The "coin attachment/detachment plate 26" is formed by integrally forming a long plate and a short plate into an L-shaped vertically long plate, and the lock casing 20
A spring 26e is attached to the inner wall of the spring 26e, which is rotatably mounted on a shaft 26a and rotates inward. The long plate has a coin receiving piece 26d with a vertical hole 26f, and the coin receiving piece 26 is inserted into the vertical hole 26f.
g is screwed, and the coin receiver 26g can be moved up or down depending on the number of coins inserted. The short plate is an adjustment piece 26b that adjusts the rotation width of the coin locking/detachable plate 26, and an adjustment board 26c is screwed to the center outer end of the adjustment board 26.
The end of c is always in contact with the head of the protruding board 21c of the customer lock 21. Reference numeral 27a denotes a vertically elongated opening in a coin passage wall 27, which will be described later, into which a coin receiver 26g is inserted.

The "passage wall 27" is formed by a hollow double side plate on one side of the lock casing 20 for allowing coins to pass downward.

The "master lock 28" is used to attach and detach the lock casing 20 and the vertical stile of the locker.

B. Function of the prior art Next, regarding the function of the lock mechanism, see Figures 12 to 1.
This will be explained with reference to FIG. "Figures 12 and 13 are before use, Figure 14 is when coins are inserted, Figure 15 is when the customer key starts turning, Figure 16 is when the customer key ends turning, and Figure 17 is when the customer key is finished turning. This shows the mutual relationship between the control plate 24, the bent piece 25 of the coin passage wall 27, the coin locking plate 26, and the recess 21b of the back end 21a of the customer lock 21 when the key is removed after rotation is complete. It is.

(a) The operation before use is such that the upper side of the tip 24c of the control plate 24 hits the bent piece 25 of the coin passage wall 27 due to the elasticity of the spring 24b, as shown in FIG. is the 10th
As shown in the figure, the adjustment board 26c is pressed against the board 21c pushed out by the key A in the rear end 21a of the customer lock 21, and the coin release board 2
6 is rotated outward, and the coin receiver 26g is inserted into the opening 27a of the coin passage wall 27. In this state, if you turn the key A inserted in the customer lock 21 without inserting a coin, the
As shown in FIG.
c slightly enters the opening 27b over the bent piece 25 of the coin passage wall 27, but the spring 2
The control plate 24 rotates upward due to the elasticity of the coin passage wall 27, and the notch 24a engages the bent piece 25 of the coin passage wall 27, preventing the control plate 24 from entering the opening 27b.
The customer lock 21 is not activated.

(b) The operation of inserting a coin, turning the customer key, and completing the locking is as follows: When the coin 29 is inserted, the coin receptacle 26 of the coin locking plate 26 will open as shown in FIG.
g is the tip 24c of the control board 24 and the coin 2
Coin 29 is placed in the position where the surface 29a of coin 9 touches
accept. Then turn the key and the 15th
As shown in the figure, since the control plate 24 is set diagonally downward, the tip 24c of the control plate 24
comes into contact with the surface 29a of the coin 29, and the tip end 24c of the control plate 24 slides downward on the surface 29a of the coin 29, causing the customer lock 21 to rotate, and as shown in FIG. 24 is moved downward and the drive shaft 23a of the door closing latch 23 is driven to force the door closing latch 23 into the door and complete the locking.

(c) The effect of removing the customer key is that if the locking described in (d) above is completed and the key is removed from the customer lock 21, the protruding board 21c of the customer lock 21 can be moved with a coin as shown in FIG. Due to the elasticity of the spring 26e of the locking/disengaging plate 26, the rear end 2 of the customer lock 21
At the same time, as shown in FIG. 17, the coin retaining plate 26 is rotated inward by the spring 26e, and the coin receiver 26g is pulled out from the opening 27a of the coin passage wall 27, causing the coin 29 to fall. do.

(d) To unlock the lock, insert the key into the customer lock 21, move the coin locking plate 26 outward, return the locking mechanism from the state shown in FIG. 16 without the coin from FIG. When the control plate 24 is rotated in the unlocking direction, the control plate 24 is rotated upward as there is nothing to prevent its rotation, and the closing latch 23 is rotated upward.
is pulled back into the lock casing 20 to unlock it, and the lock mechanism returns to the state shown in FIG. 12 before use. Although the mechanism and operation of the prior art are as described above, there are the following problems, and countermeasures have been devised, although they are incomplete.

a Problem with attaching and detaching the customer lock casing from the outside.

In cases where a locked guest lock needs to be replaced due to damage, or a guest key is lost, or an emergency unlocking is required due to a special incident and there is no spare key, the master lock is operated to release the engagement between the lock casing and the locker frame, and forceful measures are used to pull the closing latch out of the door, which would damage the door and lock. To solve this problem, a special master lock for emergency door opening is attached to the locker in addition to the master lock that is normally used.
This makes the cost of manufacturing a rocker high.

b. The problem of having a spare key.

In order to avoid the production cost problem mentioned in section a, it is necessary to prepare a spare key in advance. However, if spare keys are not properly managed, they may not be ready in time for emergencies. Also, preparing a spare key is not desirable as it may violate people's privacy.

c. Problems with relocking after emergency unlocking using a spare key and coin insertion during periodic lock inspections.

After emergency unlocking with a spare key or before periodic lock inspection, the lock mechanism is in a state where the control board cannot be unlocked unless a coin is inserted as shown in Figure 12.
It is inconvenient that coins are required in any case, so it was hoped that a mechanism could be developed that could be operated without coins. The inventor of this case previously devised a utility model application published in 129585/1985, ``Customer Lock Detachment Device,'' which solved problems a and b above, but problem c above still remained.
The structure of the invention and its effects will be outlined below with reference to FIGS. 5 to 8. Figure 5 is a front view of the customer lock in the unlocked state with the key removed. Figure 6 is a side view of Figure 5. Figure 7 is an explanatory diagram of the mechanism seen from the back of the lock casing. Figure 8 is the lock casing. It is a front view of the insertion hole of the customer lock 30 having levers 30a on the top and bottom of the outer cylinder, a master lock 31 having a supporting lever 31a, and a fitting notch 3 in the upper part.
Below one side of the fitting plate 32b forming the fitting plate 2a
A connecting plate 32 that continuously forms an operating rod 32d having two cutouts 32c, 32c.
The customer lock 30 is arranged in the upper part of the lock casing 33, and the master lock 31 is arranged in the lower part, and the lower lever 30a of the customer lock 30 is fitted into the fitting notch 32a of the connecting plate 32. The supporting lever 31a of the master lock 31 is positioned between the cutouts 32c, 32c of the lock 32 to connect both locks, and the customer lock 30 is supported by the master lock 31. Therefore, when the master lock 31 is driven and the lever 31a is rotated downward to release the support of the connecting plate 32, the connecting plate 32 is pulled down and the customer lock 30 is disengaged from the connecting plate 32. ,
The customer lock 30 is rotatable, and the insertion hole 34 of the customer lock 30 in the lock casing 33 has insertion holes 34a, 34a for the levers 30a, 30a formed diagonally and integrally as shown in FIG. , the customer lock 30 is rotated in the direction of movement of the clock, and the above-mentioned insertion holes 34a, 34a are inserted.
If you match the above levers 30a, 30a and pull the customer lock 30 outward, the customer lock 3
0 can be extracted from the outside. Note that the operation for attaching the customer lock 30 may be performed by reversing the above procedure. Thus customer lock 3
0 can be attached and detached from the outside of the lock casing 33, solving the problem a of the prior art, and furthermore, the customer lock 30 can be rotated with the lock casing 33, and the key can be removed after locking. As shown in FIG. 17, the locking mechanism has the effect that the coin locking plate 26 rotates inward, so that when the customer lock 30 is rotated in the unlocking direction, the lock is unlocked and emergency unlocking can be performed. This solved problem b of the prior art, but
Incidentally, this problem of relocking after emergency unlocking and c was not resolved.

In particular, the above-mentioned problem of relocking after emergency unlocking is such that when emergency unlocking is performed, the lock mechanism will not operate as if the key had been removed and the coin latching release plate 26 would remain rotated inward as shown in Figure 18. In this state, the tip 24c of the control board 24 collides with the bent piece 25 of the coin passage wall 27, so it is necessary to use a spare key and insert a coin in order to lock the door again.If this is not available, the door must be locked again. This is something that cannot be done.

(Problems to be solved by the invention) The invention makes it easy to unlock the customer lock in an emergency, makes it possible to relock the lock after the emergency unlocking, and eliminates the need to insert a coin during regular function inspections. To provide an emergency unlocking and coinless locking mechanism for a coin locker.

(Means for solving the problem) The configuration of the present invention utilizes the above-mentioned "customer lock detachment device" and also improves the control board of the drive shaft of the door closing latch.The means will be described below. .

(b) A connection that is interposed between the ``master lock located below'' and the ``customer lock located above the master lock, is supported by the master lock, and moves up and down by the drive of the master lock. and a "customer lock to which the connecting plate attaches and detaches by moving the connecting plate up and down," and connects the connecting plate and the customer lock by driving the master lock and pulling down the connecting plate. In the lock of the coin locker where the customer lock was made detachable from the lock casing from the outside, (b) ``the control board that controls the drive of the drive shaft that operates the door closing latch'' and ``the inserted The control board has a protrusion protruding from the center lower part of the inner side of the control board, and the coin release board can be opened by removing the key from the customer lock. ``The board that was supported by the tip of the key in the back end of the customer lock'' is replaced by the ``end of the adjustment board of the adjustment piece that adjusts the position of the coin holder of the coin holder release plate.'' When the customer lock is removed from the outside, it is pushed into the back end of the customer lock by being pressed by the elasticity of the spring of the detachment plate, and at the same time, the coin lock/release plate is rotated inward. It is designed so that the "inner surface of the coin receiving piece of the coin locking/detachable plate" comes into contact with the "protrusion of the control plate", and (c) emergency unlocking of a locked lock and relocking after emergency unlocking. drives the master lock, pulls down the connecting plate, removes the connecting plate from the customer lock, then rotates the customer lock in the unlocking and closing directions, and removes the protrusion on the control plate. slide upward and downward on the inner surface of the coin receiving piece of the coin locking/detachable plate, and rotate the control plate for emergency unlocking and relocking; (d) locking and unlocking without a coin; As in (c) above, detach the connecting plate from the customer lock and rotate only the outer cylinder of the customer lock in the unlocking direction;
〓〓〓〓〓
Set the function of the guest lock to the locked state and remove the key,
Next, rotate the customer lock in the locking and unlocking directions,
The protrusion of the control plate is slid downward and upward on the inner surface of the coin receiving piece of the coin locking/disengaging plate, and the control plate is rotated to lock and unlock the lock without a coin.
