is drilled.

Both ends of the renter's lock 3 and the guard lock 4 are rotatably supported by a cylindrical portion 15 formed on the inner bottom surface of the case 1 and the lid 7, and one end has a key groove 16, 17 into which a key is inserted. each formed.

Further, a sector-shaped cam portion 18 that engages with the operating groove 14 formed in the gap 2 is integrally formed at the lower part of the renter's lock 3, and when the renter's lock 3 is rotated by key operation, the cam is activated. The cam lead surface of the part 18 slides into the operating groove 14, and the bolt 2 is recessed into the case 1 along the guide post 10 from the state shown in the figure.

One of the rotating members 5 and 6 is for a renter's lock, and the other rotating member 6 is for a guard lock. has been done.

Each of the rotating members 5 and 6 is provided with a filigree spring 19, 19 on the guide post 10 side, and the tip of each filigree spring 19, 19 is in contact with the side surface of the case 1.

As a result, each rotating member 5, 6 has its swinging end at the guide post)1
They are biased in directions that intersect with each other with 0 as the fulcrum.

This swinging end faces a retaining protrusion 20 that is integrally provided on the guide portion 12 of the gap 2, and prevents the bolt 2 from sinking into the case 1.

When the renter's lock rotating member 5 rotates the key inserted into the key groove 17 of the renter's lock 3, the renter's lock rotating member 5 comes into contact with this key and is biased, thereby biasing the filigree spring 19. The bolt 2 can be retracted by rotating against pressure so that each of the engaging recesses 21 formed at each swinging end coincides and engages with the engaging protrusion 20. be.

Further, a locking claw portion 22 that engages with the guard lock 4 is formed at the other end of the guard locking rotating member 6, and is formed on the side edge of the swinging end side (appearing at the left end in FIG. 1). In this case, a locking step 23 is cut out, and an engaging recess 24 is formed in line with the locking step 23.

Each of the engagement recesses 24 is provided at two locations or in the width direction (swivel direction) corresponding to locking and unlocking so that the engagement protrusions 20 coincide with each other when the guard lock 4 is locked and unlocked. It is formed to be long in the direction of motion).

Further, a substrate 25 is integrally provided on the side of the guide portion 12 in the gap 2, and this substrate 25 protrudes laterally from a notch 26 formed in the side of the case 1.

The lock frame 8 is arranged on the base plate 25 so as to be pivotable about a screw 27 screwed into the base plate 25.

A lock pawl 28 is integrally bent at one end of the lock frame 8, which is the pivot end.

This lock claw 28 is connected to a hole 2 formed in the side of the case 1.
9 protrudes inward from the case, and its tip is connected to the locking step 2.
It is facing 3.

Further, a long hole 30 is formed at the other end of the lock frame 8.

The solenoid 9 is attached to the side of the case 1 extending from the other end of the lock frame 8, and has a solenoid plunger 31 projecting above the elongated hole 30.

The plunger 31 has a protruding pin 32 that fits into the elongated hole 30, and a compression coil spring 33 is inserted between the pin 32 and the case of the solenoid 9.

As a result, the other end of the lock frame 8 is constantly pressed,
A lock pawl 28 formed at one end is brought into contact with the locking step 23 of the rotating member 6.

Then, the rotating member 6 is biased by the lock claw 28, so that the engagement recess 24 no longer faces the engagement protrusion 20.

In other words, the rotating member 6 is locked in the locked position.

Further, by energizing the solenoid 9 by remote control, the plunger 31 is retracted against the spring pressure of the compression coil spring 33, and the lock pawl 28 is separated from the locking step 23.

Next, the operation of each part in the unlocking operation of the coin safe lock configured as described above will be explained.

First, the case where the guard lock 4 and the renter's lock 3 are operated by keys will be explained.

When a matching key K is inserted into the key groove 16 of the guard lock 4 and rotated counterclockwise by a predetermined angle, the locking claw portion 22 of the rotating member 6 is urged into contact with the key K. Because
Against the spring pressure of the filigree spring 19, the swinging end of the guide post rotates counterclockwise around the intersection point 10.

Then, as shown in FIG. 3, each locking step portion 23 is separated from the lock claw 28.

At this time, if there are two engagement recesses 24, the other engagement recess 24 corresponds to the engagement protrusion 20.

Thereafter, by inserting a suitable key into the keyway 17 of the renter's lock 3 and rotating it clockwise by a predetermined angle, the respective engaging recesses 21 of the rotating member 5 will align and engage the locking protrusions. Facing 20.

At the same time, due to the cam action of the cam portion 18, the bolt 2 moves along the guide post 10, and the protrusion 11 at its tip sinks into the case to open the lock.

Further, the lock frame 8 slides with the gap 2 while the pin 32 guides the elongated hole 30.

Next, when the solenoid 9 is energized by remote control, the lock frame 8 pivots around the screw 27, and as shown in FIG.
Move away from 3.

Then, since the rotating member 6 is pressed by the filigree spring 19, the engagement recess 24 coincides with and faces the engagement protrusion 20 as described above.

Therefore, from now on, the renter's lock 3 can be unlocked by operating the key, as described above.

Note that even if the solenoid is energized at the same time as the guard lock 4 key is operated, there will be no problem with the unlocking operation, and the renter's lock 3 will be locked even if the guard lock 4 key is removed or the solenoid is deenergized after unlocking. There is no problem with operation at all.

Furthermore, in the above embodiment, the casing of the entire lock and the mounting position on the coin safe unit are omitted for the sake of simplifying the explanation, but as those skilled in the art would naturally be familiar with these, the explanation thereof will be omitted. .

As explained above, the coin safe lock according to this invention has the above-mentioned structure and can be unlocked by either mechanical lock operation or electrical remote control. This eliminates the need for staff members to go to the place where the safe unit is located and witness the situation, which eliminates the inconvenience of dealing with customers, and allows staff to be present as needed, making it possible to diversify customer service. .

Additionally, in this invention, a lock frame is provided which is connected to the mechanical locking mechanism of the guard lock, and this lock frame is adapted to move the lock frame away from the locked position when the solenoid operates or when the guard lock is unlocked.
