Next, the l pair of side plates 26 and 26' of the back cover 4 are connected to the side plates 26 and 26' of the front cover 3.
It is erected at a distance such that it slides into contact with the pair of side plates 17, 17' from the inside, and its lower end edges 34, 34' are inclined at a predetermined angle to extend slightly above the lower end 35 of the rear wall plate 24. It has arrived.

Further, at a predetermined corresponding portion of the side plate 26, 26', there is a latching protrusion 23.2 formed to protrude from the side plate 17, 17' of the front lid 3.
A pair of notches 36 and 36' are formed which engage the 3'.

The cutout 36,36' has the shape shown in FIG.
The back cover 4 can be freely removed by rotating backwards.

Note that 37 is a curved chute plate installed at the lower end inside the box body 1.

Next, to explain the usage state of the key box according to the present invention, when the key 38 is stored as shown in FIG.
The keys 38 are stably stored in a box formed by the rear wall plate 24 and the side plates 26 and 26' of the back cover 4. In this case, a large number of frames 2 are attached to the box body 1, and each key 38 is Even if the key 38 is stored, it is extremely easy to select the key 38 to be used based on the illustration drawn on the transparent plate 20 of the front cover 3 attached to each frame 2, and it is also possible to determine whether the key 38 is actually stored or not. This can be easily confirmed by looking through the transparent plate 20.

Next, when you want to take out the stored key 38, press the button 31 that slightly protrudes from the hollow chamber 8 of the frame 2 as shown in FIG. The back cover 4, which is pushed in a predetermined distance and is pivoted to the rod portion 32 of the button 31 via the pin 29,
The key 38 rotates backward around the concave portion 28.28' at 7.27', and the rear wall plate 24 of the back cover 4 separates from the bottom wall plate 16 of the front cover 3, and the key 38 falls downward, and the chute plate 37 and reaches the extraction hole 6.

As mentioned above, the front cover 3 always has a moment of forward rotation around the pivot projections 22 and 22', but the side plates 17,
The latch protrusion 23, 23' of 17' is connected to the side plate 26 of the back cover 4,
Since the back cover 4 is engaged with notches 36 and 36' formed in the back cover 26', it will never rotate forward unless the button 31 is pressed to rotate the back cover 4 backward.

Also, even after the back cover 4 is rotated backward, the key 38 remains in the bottom wall plate 1 of the front cover 3.
6, the weight of the key 38 cancels out the bending moment and the front cover 3 does not rotate forward, but rotates forward only after the key 38 falls, and the bottom wall plate 16 of the front cover 3 is back cover 4
It rotates until it comes into contact with the side plates 26, 26' and stops.

After taking out the key 38, if you release the button 31, the elastic force of the spring 33 will cause the button 31. returns to the front again,
Therefore, the back sparrow 4 also rotates back to its original state, and the front cover 3, which is in contact with the back cover 4 at the bottom wall plate 16, is also pressed by the back cover 4 and returns to its original state.

Next, if you want to put the key 38 back into the key box after use, press the button 3F and the key box will be in the state shown in FIG. 5 by the same operation as when taking out the key 38. When the button 31 is released after placing the cover on the front cover 3, the back cover 4 and the front cover 3 are respectively rotated back to the state shown in FIG. 3.

In addition, during such return rotation, since the bottom wall plate 16 of the front cover 3 is bent at a predetermined angle, the bottom wall plate 16 is bent until just before the front cover 3 and the back cover 4 complete the return rotation. 16 maintains an approximately horizontal inclination, so that the key 38 will not slide down before the return rotation is completed.

In short, in the key box according to the present invention, the upper end of the back cover 4 housed in the hollow box main body 1 is pivotally supported by the upper end of the frame 2 tightly fitted to the front wall surface of the box main body 1.
The rear end of the rod portion 32 of the button 31, which protrudes slightly from the front surface of the frame 2 and has a spring 33 wound thereon, is pivoted at a portion of the back cover 4 slightly below the pivot portion, while being pivotally supported by the frame 2. The front cover 3 is fitted into the front cover hole 7 on the front wall of the frame 2, and the bottom wall plate 16 of the front cover 3 is formed to be inclined at a predetermined angle rearward to abut against the back cover 4. Lid 4
A locking protrusion 23.23' formed in a predetermined portion of the front cover 3 is removably engaged with a notch 36.36' formed in the front cover 3, and a key 38 is accommodated by the back cover 4 and the front cover 3. Since the box body is formed, the key 38 falls from the bottom wall plate 16 of the front cover 3 and reaches the ejection hole 6 by simply pressing the button 31 without requiring any electric power or other power or driving device. It can be easily taken out, and the front cover 3 has a hooking protrusion 23.23 formed protrudingly on its side plate 17.17'.
' is engaged by the notches 36, 36' of the side plates 26, 26' of the back cover 4, so it will never rotate forward unless the button 31 is pressed, and when the button 31 is released after taking out the front cover
The back cover 4 is immediately rotated back to return the key box to its original state, and if you wish to return the key 38 to the key box, press the button 31 and place the key 38 on the front cover 3 which has been rotated forward. All you have to do is release the button 31, and the key 38 can be stored and taken out very easily with a single button operation. Also, since the key 38 is stored in the key box and is not exposed, it is possible to prevent carelessness from outsiders and to keep the room tidy. Furthermore, by fitting a transparent plate 20 with an appropriate illustration into the viewing window 19 drilled in the center of the front wall plate 15 of the front cover 3, the box body 1 can have many frames. Even if the body 2 is attached to store different keys 38, it is extremely easy to select the key 38 that you want to use based on the illustration drawn on the transparent plate 20.
