Abstract

<P>PROBLEM TO BE SOLVED: To solve the following problem: a conventional door locking mechanism is formed by linking all gate bars together by a link, and therefore when the locking mechanism is attacked and when one portion thereof is detached, all the gate bars are detached from each other. <P>SOLUTION: A new door locking mechanism stands an attack on the door by a portable power tool etc., by mounting a buffering spring on a lock shaft, and therefore the gate bars must be individually unlocked. When the door is opened/closed by rotating a key, all the gate bars are linked to the link mechanism in a lump, and the door is opened/closed. On the other hand, when the door is attacked from the outside by the portable power tool etc., by virtue of use of the buffering spring, even if the gate bar is attacked, breakage of the gate bar is not transferred to the link mechanism due to the buffering spring. Thus before opening/closing the door, all the gate bars must be individually attacked and unlocked, and therefore a long time is spent for unlocking the door, which imparts high crime prevention to the locking mechanism. <P>COPYRIGHT: (C)2009,JPO&INPIT

It is in the configuration that requires unlocking of the bag.

  Because it is configured as described above, when the door is opened and closed by rotating the key, all the hooks are linked to the link mechanism to open and close the door at once. By constructing it so that it always acts in the closing direction, the door does not open and close unless all the swords are attacked and unlocked, making it possible to earn time and to have a high crime prevention mechanism.

  According to the present invention, it is possible to provide an electronic device device with high security that can earn time for unlocking all the bags by making the bags independent from attacks on the door by a portable electric tool or the like from the outside. Can do.

  Hereinafter, an embodiment of the present development will be described with reference to FIGS. The present embodiment relates to an electronic apparatus device such as an ATM (Automatated Teller Machine) employed in a safe or a financial institution system.

  First, FIG. 1 is an external view of an electronic apparatus device in which a housing body 1 and a housing door 2 according to the present embodiment are combined, and FIG. 2 is an external view of the housing door 2 shown in FIG. is there. FIG. 3 is an external view of the lock mechanism 3 attached to the housing door 2, and FIG. 4 is a detailed view of the lock mechanism 3 of FIG. 3. The schematic structure will be described with reference to the external view.

  An electronic device is an electronic device that is installed in a financial institution and performs transactions such as cash storage, deposit, withdrawal, etc. The conventional electronic device is composed of a case body 1 and a case door 2. The housing door 2 is provided with the lock mechanism 3, the housing body 1 is provided with a fitting hole 16, and the lock shaft 7 of the locking mechanism 3 enters the fitting hole 16 so that the housing door 2. Is a device that locks in a closed state. The case door 2 can operate the lock mechanism 3 by rotating the lock 15 in the release direction to open the case door 2. However, the case door 2 can be opened without rotating the lock 15. In such a case, since the lock shaft 7 enters the fitting hole 16, it cannot be opened even if the casing door 2 is pulled in the opening direction. When trying to open the housing door 2, the lock 15 is rotated, the lock mechanism 3 is activated, the lock shaft 7 is disengaged from the fitting hole 16 on the main body side, and the housing door 2 can be opened. it can.

  The door itself has a lock 15, and a lock 18 is attached to the lock 15 and rotates with the rotation of the lock 15.

  The key metal 18 is connected to the link 11, and the other end of the link 11 is connected to the lever 5.

  The link transmission order is as follows: the lock 15 is rotated upward, the key 18 is rotated, the link 11 is moved up and down, the lever 5 is rotated, the lock shaft 7 is removed from the fitting hole 16, and the lock shaft 7 is released. FIG. 5 shows the state.

  When an attack to the door by a portable electric tool or the like is applied to the lock mechanism 3 as in the prior art, the lock shaft 7 advances in the direction of the arrow, the connected lever 5 rotates, and the link 11 moves up and down. The lock shaft 7 is removed from the fitting hole 16 and the door is opened.

  In FIG. 4, unlike the conventional one in which the lock shaft 7 and the lever 5 are directly connected, the connecting plate 6 is fixed between the lever 5 and the lock shaft 7 with a pin on the lever 5 side and a pin 12 on the lock shaft 7 side. It has a structure.

  FIG. 5 is a state diagram in which the lock 15 is rotated and all the lock shafts 7 connected to the link 11 are removed from the fitting holes 16 and the door is opened. Since the connecting plate 6 pulls the lock shaft 7 and removes the lock shaft 7 from the fitting hole 16, the mechanism is similar to the lock mechanism 3 in which the lock shaft 7 and the lever 8 of FIG. 5 are directly connected.

  FIG. 6 is a view in which the housing door 2 is attacked by a portable electric tool or the like from the direction of the arrow, and the pin 12 assembled to the lock shaft 7 can be horizontally moved through the connecting plate guide hole 14 of the connecting plate 6. In this way, the spring 8 attached to the lock shaft 7 is pulled in the direction of the arrow to stop the lock shaft 7 moving in the release direction. The lock shaft 7 advances in the horizontal direction by the force from the arrow direction, but the force is not transmitted to the link 11 by the connecting plate 6, and the other lock shafts 7 are not affected.

  FIG. 7 is a view in which the lock shaft 7 is attached to the lowermost portion of the link 11. It is called a half-locked state that each lock shaft 7 is in a semi-locked state, and in order to prevent the half-locked state, the lock shaft 7 is directly attached to the lowermost part of the link 11 in the downward direction. The main body lock shaft receiving plate 9 is made and the lock shaft 7 cannot enter the fitting hole 16 to prevent the housing door 2 from being completely closed in the half-locked state.

  FIG. 8 is a view in which a fixed position detection sensor is attached to the lock mechanism 3. When one lock shaft 7 is unlocked against an attack on the door by a portable electric tool or the like, the other lock shaft 7 has entered the fitting hole 16 and it is not known from the outside that the lock is released. Therefore, when the fixed position detection sensor 17 is arranged near the lock shaft and is brought into a semi-locked state by hitting the pin 12, the fixed position detection sensor is activated, and the housing door 2 remains in the half-locked state. Detect closing.

  1 to 8, the lock 15 is rotated and the link mechanism 3 is interlocked to open the housing door 2. However, the link mechanism 3 can be interlocked by rotating the handle.
