[0018]
Next, the operation of this embodiment configured as described above will be described.
First, the operation of opening the door from the closed state will be described with reference to FIG. FIG. 4A shows a state in which the first and second stays 20 and 21 are engaged with the stopper 35 to close the door. If the knob 25 is pressed and moved from this state in the direction of arrow X as shown in FIG. 5B, the rack 25c rotates the second pinion gear 31, and at the same time, the second pinion gear 31 is moved to the first sliding member 32. Is pushed in the direction of arrow Y.
[0019]
Accordingly, the second stay 21 is moved in the arrow Y direction. At the same time, the first stay 20 is also moved in the direction opposite to the arrow Y by the first pinion gear 22, and both the first and second stays 20 and 21 are separated from the stopper 35, and the engagement is released to open the door.
In this case, since the second pinion gear is composed of two large and small gears, and the rack 25c of the knob 25 is engaged with the smaller pinion gear, the movement of the first sliding member 32 is expanded.
[0020]
Next, the lock by the key will be described with reference to FIG. The figure shows only the main part. In FIG. 5A, the projection 29a of the cylinder key 29 is below and is engaged with the hole 33a of the second sliding member 33. When the key cylinder 29 is rotated 90 ° in the direction of the arrow Q from this state, the second sliding member 33 moves as shown in (b), the knob 25 and the P portion of the case 30 come into contact with each other, and the knob 25 does not move. The first and second stays 20.21 are locked.
[0021]
The knob 25 cannot be pushed when the key cylinder is locked. Furthermore, even if it is going to open the door grab by moving the first stay 20 or the second stay 21 in the door grab using a wire or the like, the present embodiment takes measures against it. That is, as shown in FIG. 5, when the second sliding member 33 is moved, the dimension W1 between the first stay 20 and the auxiliary stay 20c shown in FIG. And become smaller.
[0022]
As an example, if W1 = 8mm, W2 = 2.75mm, and the unlocking strokes of the first and second stays are 5mm, even if the first and second stays 20, 21 are moved by picking, Since the first and second stays 20 and 21 cannot move, the lock cannot be released. Even if the first and second stays 20 and 21 are moved with a strong force, the second sliding member 33 and the second stay 21 are wrapped (in the state shown in FIG. 6C) in the direction to open the door grab. It cannot be rotated and opened. In other words, double security is obtained. Fig. 6 (a) shows that the knob is not activated (during normal use) + key cylinder unlocking, Fig. 6 (b) shows that the knob is unlocked (during normal use) + key cylinder locking, and Fig. 6 (c) shows the key. The cylinder is locked.
[0023]
As described above, in this embodiment, since the knob is pressed, the operation from the driver is extremely good. Further, since the stays for locking are on the left and right, the installation quality is improved, and since the left and right stays are interlocked with the rack and the pinion gear, the synchronization is ensured. Further, in the locked state, the knob cannot be pushed and moved, and the stay cannot be pulled in. Also, since it is resistant to picking, the anti-theft property is excellent.
[0024]
The present invention can also be applied to types other than the key cylinder. Further, as shown in FIG. 7, the stay can be used as a hinge shaft and can be applied to a door that can be opened to the left or right.
[0025]
