DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double lock used in each box of a safe box installed in a bank or the like, and in particular, a compact lock used for a large number of small safe boxes installed in a small space. It is.

[0002]

2. Description of the Related Art Conventionally, a safe deposit box installed in a bank or the like has a large number of safe deposit boxes based on individual use contracts with customers in a safe deposit box provided with a specific entrance. In addition, double locks are used for the doors of the cells, each of which usually has a customer lock individually owned by a customer and a bank lock managed by a person in charge of the bank. However, such a double lock requires extremely troublesome cooperative work and troublesome procedures between the customer and the bank, and furthermore, the bank needs a person in charge of a safe deposit box at all times, which is a heavy labor burden. .

In recent years, in order to reduce such labor, a method of centrally managing the operation of unlocking and unlocking a bank lock using a computer has been developed. However, according to the new system, the electric system is the mainstream, and there is a risk that the whole system will be down even if there is an electric failure in any one of the safe deposit boxes. Also, this method could not be applied to a safety deposit box provided with an existing double lock.

As a method for solving these problems, the present inventor employs a mechanical unlocking method to provide a safe box even if one of the locks breaks down, provided that there are many safe boxes. We have already proposed a double lock that does not affect the locks of other boxes and that has reduced the labor burden on the bank side and a safe deposit box utilization system using this (Japanese Patent Application No. 2-27).
7980).

However, the above-mentioned improved double lock is, for example, as shown in FIG. 1 and FIG. 2, an unlocking card which is attached to the upper surface of the opening / closing door (1) of the safe box and corresponds to the bank lock of each double lock. (Five
0) and the movable lid (51) of the lock is slid to expose the customer lock (52), which is a cylinder lock for the customer, provided on the door (1) as shown in FIG. The user unlocks this cylinder lock with his lock key. By the way, in general, safe deposit boxes cannot take up a sufficiently large space depending on their installation locations, and thus recently, safe deposit boxes provided with a large number of small squares have been made. On the other hand, the opening and closing door (1) of the safety box equipped with the double lock is a keyhole (5
2) The system can be concealed by sliding the movable lid (51), so it becomes unnecessarily large (that is, large in the horizontal direction) and cannot be attached to the recent small-sized doors (1). There was such a problem. In order to further reduce the size, when the door is opened when using a certain mass, the movable lid (51)
However, since the door hits the door or movable lid (51) of the adjacent cell, the opening / closing door (1) cannot be fully opened, and the width of the inner box in the cell must be reduced. That is, the improved double lock described above could not sufficiently cope with miniaturization of the safe deposit box.

In view of the above, as a result of various studies in view of the above, the present invention provides a mechanically and compact double lock which can sufficiently cope with a small safe box, and an existing double lock. This is a method of attaching to a safe box opening and closing door. That is, the double lock of the present invention is configured such that the base end of the fixing member is rotatably supported on support plates erected on both sides of the end of the frame fixed to the opening / closing door so as to surround the keyhole, and the fixing member is fixed. Attach a slide cover that slidably engages the tip, set up a pin on the upper surface of the fixed member, and insert a card key insertion slot for inserting a card key between the upper surface of the fixed member and the inner surface of the slide cover. The elastic member is provided and the slide cover can be moved up and down, and a card key provided with a perforated hole at a position corresponding to the pin is inserted from the card key insertion slot to fix the slide cover when the slide cover can be pressed down. And a slide means for releasing the engagement between the slide cover and the slide cover are formed on the fixed member and the slide cover, and the slide cover is engaged when the fixed member and the slide cover are engaged. The slide cover and the frame are provided with locking means for locking the frame body with the slide cover and releasing the lock between the slide cover and the frame at the time of disengagement. It is effective to provide the upper surface of the fixing member to a member detachably attached to the fixing member.

Further, according to the mounting method of the present invention, the frame of the compact double lock of the present invention is fixed around the customer lock and the bank lock attached to the opening / closing door of the existing safety box, and the bank lock is opened. It is characterized in that it is fixed in a locked state.
