Description

[Detailed Description of the Invention] Industrial Application Field The present invention is a lock management device G for checking the locked state of a plurality of locks.
Regarding C'.

Configuration of conventional example and its problems When nine devices each of which requires locking are installed in a room with a door to be locked, and the door needs to be locked after all devices are locked, conventional methods Because the locking system relied on the memory of the person locking the door, there was a possibility that a human error could occur, such as misunderstanding that all devices had been locked and locking the door.

Purpose of the invention: The present invention has been made to solve the above-mentioned conventional problems. This is a device that can reliably prevent human locking errors, and is a device that can be used indoors. ? If you don't have it, take out the door key □ □
First, it is an object of the present invention to provide a locking management device that prevents the door from being locked.

Structure of the Invention In order to achieve the above-mentioned object, the present invention has a shaft that can be operated to enter and exit, the shaft can enter only when a key i is inserted, and the key cannot be removed in this retracted state. A plurality of locks were installed that could be easily moved, and the design was such that the protrusion of one of the shafts before opening the lock could be destructed when the shafts of the remaining locks entered. As a result, all the necessary locks in the room are mechanically confirmed and locked. Unit 8 is a platform to prevent an artificial lock.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will now be described with reference to the drawings. FIG. 1 and FIG. 2 show a lock management device according to the present invention.
The figure is a plan view showing a state in which, for example, a key for locking a door has been removed from the lock management device and can be used, and FIG. It is a top view showing a state.

In the drawing, 1 is a main lock, 2 is a door key inserted into the main lock 1, 3 is a shaft supported by the main lock 1 so that it can be operated in and out; An entry operation is possible only when the door key 2 is inserted, and the door key 2 cannot be removed from the main lock 1 when the shaft 3 is in the entry state.

Numeral 4.7 is a secondary lock into which a key 5.8 for an indoor device is inserted, and each shaft 6 and 9 is a secondary lock 1.
Similarly, the entry operation is possible only when the keys 5, 8 are inserted, and in this state, the key 5.8 cannot be removed from the locks 4, 7.

The secondary locks *j4.7 are arranged oppositely on the left and right sides so that the shafts 6 and 9 protrude toward each other when the respective shafts 6 and 9 protrude, and at least one of the shafts 6 or 9 is protruding, the shaft 3 of the main lock 1 is connected to the protruding shaft 6 or 9 of the secondary lock 6°9, as shown in FIG.
Or it will collide with both and become unable to eject.

When an ill that requires locking is installed in a room that has a door to be locked, the lock management device shown in FIGS. The keys 5 and 8 are inserted and held in the respective slave locks 4.7. After opening the door □ using the key 2 on the door, insert the key 2 into the main lock 1 shown in Fig. 1, enter the shaft 3 as shown in Fig. 2, and then open the door as shown in Fig. 2. By protruding the shaft 6.9 of the lock 4, 7 and removing the device key 5.8 from the subordinate lock 4.7, the key 5.8 can be used for the device inside the room. Next, when locking the room, after locking the device in the room with the key 5.8 of the device, insert this key 5.8 into the secondary lock 4.7 in Fig. Insert the shaft 6.9 of the main lock 1, then protrude the shaft 3 of the main lock 1 as shown in Figure 2, and lock the door I! Remove 2 and lock the door.

As long as the shaft 3 of the main lock 1 is kept protruding in this way, the Duke's key 2 cannot be separated from the lock 1 and activated, so the door can be locked without any of the devices in the room being locked. There is no such thing. ,.

FIGS. 3 and 4 illustrate devices installed indoors, such as stoppers, that require locking. The third factor shows the unlocked state, and FIG. 4 shows the locked state. In the drawings, reference numeral 10 designates a stopper that can be rotated by 90 degrees, and has a knob 11 for rotation at the top.
The diagram shows the occlusion condition. 12 is a lock provided near the stopper 10; 13 is the shaft of the lock 12; one of the keys 5.8 of the device shown in FIGS. 1 and 2 can be inserted into the lock 12; These are, for example, locks 1.4' in Figures 1 and 2.
, 7. For example, when the shaft 13 enters, the plug 10 is rotatable, but when the shaft 13 is extended, the shaft 13 and the plug knob 11 engage, and the plug 10 becomes unrotatable. There is.

Accordingly, in FIG. 4, the shaft 13 of the lock 12 causes the stopper 10 to remain closed.

As described in detail, according to the present invention, any one of the plurality of keys cannot be removed from the lock in which it is inserted until all the remaining keys are present. If one of the keys is used as a lord's key and the remaining keys are used for a device that requires locking that is installed in a room with a door, the jl! Since the lock is checked mechanically, it is effective to prevent human locking errors such as locking the door without locking the devices inside the room, thereby ensuring crime prevention and disaster prevention.
