Description

[Detailed description of the invention] The present invention provides a coin-controlled safe that can be locked by inserting a coin.
If the lock part is forcibly removed by pulling it forward and breaking it, the bolt that closes the door will be kept in a closed state that cannot be operated from the outside. , hence,
This is characterized by improving the theft prevention properties of the safe.

A safe deposit box installed in each room of a hotel, inn, etc. has a coin control lock attached to its door and is configured so that it can be locked by inserting a coin. However, the biggest disadvantage of this type of safe is that if the lock is forcibly removed using a screwdriver, etc., the locking function is completely lost and the door can be opened easily. It was a special occasion.

The present invention is configured so that when the lock is forcibly removed as described above, an emergency lock is activated on the door, making it completely impossible to open the door by external operation. This invention relates to a coin-controlled safe equipped with an emergency closing device, which is characterized by eliminating the problem of theft.

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

In the figure, 1 is a safe door, and a coin control lock A is attached to the front thereof. The coin control lock A has a built-in stopper mechanism that is released when a coin is inserted, and the cylinder lock A is allowed to rotate in the locking direction only when a coin is inserted through a key (not shown). It is designed so that

Reference numeral 2 denotes a frame provided near the back of the safe door 1, to which the main lever mechanism of the present invention is attached.

Reference numeral 3 denotes an operating rotating shaft whose one end is interlockably connected to the cylinder lock a of the coin control lock A, and the other end protrudes from the frame 2 so as to face the rear of the safe. 4 is a sheath tube into which the rotating shaft is loosely fitted.

Reference numeral 5 denotes a locking lever having a bar rod 6 attached to the tip thereof so that it can be inserted into the safe container side from the side edge of the safe door 1, and the locking lever 5 has a guide rod 6 drilled in the center thereof. The frame 2 is inserted into the oblong slot 5a.
By fitting a guide shaft 7 implanted in the guide shaft 7, it is supported so as to be slidable in the left and right direction.

Reference numeral 8 denotes a lock stopper which is rotatably attached to a pivot shaft 9 installed in the frame 2, and its tip is engaged with a locking step 5b provided on the upper edge of the locking lever 5. A hook portion 8a is formed for locking the locking lever 5 in a locked state. Normally, the lock stopper 8 has its proximal end in contact with the guide shaft 7 and its distal end hook 8a is kept in a state disengaged from the locking step 5b of the locking lever 5. If the safe is tipped over,
That is, when the bolt rod 6 is rotated 90 degrees counterclockwise in FIG. 2 so that it is positioned upward,
The lock stopper 8 rotates under its own weight, and its tip end hook 8a engages with the locking step 5b, thereby locking the locking lever 5 in the locked state. (This functions effectively when an emergency lock is activated by a lock lever 10, which will be described later).

Reference numeral 10 denotes a lock lever whose base end is interlocked with and removably fitted into the end of the operating rotating shaft 3 described above, and has a hook-shaped portion 10a at its tip for locking to the guide shaft 7. is formed,
Further, the lock lever 10 is interlockably connected to the end of the locking lever 5 described above via a pivot pin 11. 10b is the lock lever 10
This is a spring receiving pin that protrudes slightly upward from the base end of the spring.

Reference numeral 12 denotes a spring attached to the above-mentioned guide shaft 7, and its base end is hooked to the pivot shaft 9 of the above-mentioned lock stopper 8. Further, a U-shaped temporary fixing portion 12a is provided at the tip of the spring 12.
The temporary fixing portion 12a elastically prevents the lock lever 10 from coming off by being hooked onto the end of the operating rotating shaft 3. In addition, the temporary fixing part 1 is provided at the end of the rotating shaft 3.
A groove is formed for hooking the temporary fixing portion 2a, and the temporary fixing portion 2a is configured to not come off the hook during normal use.

Reference numeral 13 denotes a lock lever end receiving pin erected at a predetermined position behind the locking lever 5, and is used to receive the base end of the lock lever 10 when the lock lever 10 is separated from the rotating shaft 3 as described later. belongs to.

The present invention has the above-described configuration, and in the locked state shown in FIGS. 1 and 2, a key (not shown) is inserted into the cylinder lock a and rotated in the unlocking direction. If you do so, the rotation axis for operation 3
As a result of the rotation of the lock lever 10 in the counterclockwise direction with respect to FIG. 2, the lock lever 10 also rotates to the state shown by the chain line in the same figure. Therefore, the lock lever 10
The locking lever 5 connected via the pivot pin 11 is pulled to the left in FIG.
The bolt rod 6 is retracted into the safe door 1 to unlock the safe.

When operating the lock, after inserting a predetermined coin into the coin control lock A and operating the cylinder lock a, the lock lever 10 is activated via the operating rotation shaft 3.
is rotated, and therefore, based on the reverse operation of the above-described unlocking operation, the bolt rod 6 protrudes toward the safe container and the purpose of locking the safe door is achieved.

Next, in the locked state shown in Figures 1 and 2, if a destructive tensile force is applied to forcibly remove the coin control lock A, at the time the lock A is removed. Operating rotation shaft 3 connected to this
will be extracted together. That is, the lock lever 1 attached to the end of the rotating shaft 3
0 is simply fitted in, and its locking depends only on the hooking of the U-shaped temporary fixing portion 12a of the spring 12. Therefore, as described above, a tensile force is applied to the control lock A. In this case, the rotating shaft 3 is also pulled forward and detached from the temporary fixing portion 12a of the spring 12, and the lock lever 10 comes off, so that the rotating shaft 3 is pulled out.

When the rotating shaft 3 is removed as described above, the spring 12 separated from the rotating shaft 3 is
Spring receiving pin 1 of lock lever 10
2b, and therefore, the lock lever 10 rotates and moves upward about the pivot pin 11 as shown in FIG. 3 due to the repulsive force of the spring. In this state, the proximal end of the lock lever 10 is in contact with the receiving pin 13, and its tip hook-shaped portion 10a is engaged with the guide shaft 7, so that the locking lever 5 is in contact with the receiving pin 13. Since the safe door 1 is held in a locked state and movement in the unlocking direction is completely prevented, the safe door 1 is held in a locked state and theft is well prevented.

In addition, in the above-mentioned locked state, even if you try to tilt the entire safe sideways (tilt it so that the bolt is positioned upward) and lower the locking lever 5 by its own weight, the above-mentioned lock lever 1
The lowering is well prevented by the locking of the lock stopper 8, and at the same time, based on the operation described above, the lock stopper 8
Since the tip hook portion 8a of the locking lever 5 is locked with the locking stepped portion of the locking lever 5, the locking lever 5 is double locked and cannot be moved at all.

It should be noted that the above-mentioned lock can only be resolved by destroying the safe door, and therefore, the primary purpose of such a lock is to prevent theft, and its mission is completed based on achieving this purpose. be.

According to the present invention detailed above, the coin control lock A
The structure is such that when a coin control safe is forcibly removed, an emergency lock is activated on the safe door, making it completely impossible to open it. By using such means, the possibility of theft can be completely eliminated, and therefore, the safe can successfully accomplish its mission as a safe for storing valuables.

As described above, the present invention has a simple structure and has excellent practical effects, so its utility value is extremely high.
