Description

[Detailed explanation of the idea] This invention relates to locks.

Conventionally, locks installed on doors of bathrooms, etc. are locked and unlocked by raising and lowering the Gremon bolt by rotating the lever, so if the lever is not returned to the predetermined position, the engagement provided on the upper stile of the door frame will close. There was a problem in the past where the door could not be opened because the hole and the Gremon bolt got stuck.

Furthermore, since rotational motion is converted into linear motion, there is a problem that the mechanism becomes complicated and large.

Furthermore, there was the problem that the door could not be unlocked from outside.

This invention solves the above problem by locking the door indoors by sliding the camera and unlocking it by pressing the button, and unlocking by rotating the button outdoors. The purpose is to eliminate it.

This idea incorporates a slider that can be raised and lowered into the lockbox by a spring and is pushed back downwards by a spring, and also has a projection for raising the slider protruding from the outside of the front wall of the lockbox. The lower end of the locking rod is connected, and the slider is provided with a vertical long hole and a through hole communicating with the lower end of the long hole and having a diameter larger than the width of the long hole. A button at the tip and a rotating engaging portion at the end are respectively protruded, and a rotatable and slidable shaft is passed through the lock box and the elongated hole, and a spring is attached to this shaft so that it can be rotated to return to a predetermined position. and a pressing force in the button direction, and furthermore, when the slider stops rising, the shaft is fitted into a through hole to prevent the slider from descending, and as the shaft rotates, the slider is released from being prevented from descending. To provide a lock provided with a shaped engagement part.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

In the figure, reference numeral 1 denotes an attached lock box, and a slider 3 that is pushed back downward by a spring 2 is built into this lock box 1.

In addition, the slider 3 is attached to the upper end of the slider 3.
Rod 4 whose upper end fits into the hole on the other side when the rod rises.
The lower ends of are connected.

The above-mentioned rod 4 is provided with a locking rod 6 which is pulled back downward by a spring 5 in the case shown, and
The upper end of the rod 4 is brought into contact with the lower surface of the piece 7 protruding from the lower end of the lock rod 6, and the lock rod 6 is held together with the rod 4.
Although the structure is designed such that the lock is raised, it may be locked using only a rod.

Further, a vertically long through-hole 8 is provided in the front wall of the lock box 1, and a shaft 10 of a pick-up 9 is passed through the through-hole 8, and the end of the shaft 10 is fixed to the slider 3.

In addition, the slider 3 has a long hole 1 in the vertical direction.
1, and a through hole 12 communicating with the lower end of the long hole 11 and having a diameter larger than the width of the long hole 11.
and is provided.

Furthermore, the button 13 at the front and back ends of the lock box 1 and the rotation locking part 14 at the end are respectively protruded so that the rotatable and slidable shaft 15 passes through the lock box 1 and the elongated hole 11. On the shaft 15,
The spring 16 provides return rotation and a pressing force toward the front wall of the lock box 1.

The spring 16 has holes 18 provided in the collar 17 of the shaft 15 and the rear wall of the lock box 1, and both ends of the coil spring 16 fitted on the shaft 15 are passed through the holes 18, respectively.

The shaft 15 also has an elongated hole 11 that fits into the through hole 12 when the slider 3 is raised to prevent the slider 3 from descending, and when the shaft 15 is rotated 90 degrees.
An oval-shaped engaging portion 19 that fits into the holder is provided.

The oval-shaped engaging portion 19 is composed of a disk that fits into the through hole 12, and a notch that leaves a parallel portion on the upper and lower edges of the disk with a width that fits into the elongated hole 11.

Although the locking portion 14 is provided with a groove on its end surface, it may have another structure.

In the figure, 20 is a mounting cylindrical body that also serves as a guide for the lock rod 6.

The lock according to this invention has the above configuration,
Next, to explain its function, as shown in Figures 1 and 5, a lock box is placed in the gap a of the hinge part of the door A that is attached to the bathroom entrance and is bent in a V-shape when opened. Insert and install 1.

At this time, press 9 and button 13 in the bathroom.
The locking parts 14 are respectively located outside the bathroom.

When the slider 3 is raised by pushing up the slider 3 after closing the door A, the lock rod 6 is raised together with the rod 4, and the upper end of the lock rod 6 is inserted into the engagement hole b provided in the upper stile of the door frame B. Push it in (as shown in Figure 3) and lock it.

At this time, the through hole 12 matches the engaging part 19, and the spring 16 pushes back the shaft 15 to fit the engaging part 19 into the through hole 12, thereby preventing the slider 3 from descending and maintaining the locked state. .

Next, to explain the unlocking method, when the button 13 is pushed and the shaft 15 is pushed in, the engaging part 19 escapes from the through hole 12, so the spring 2 causes the slider 3 to
At the same time, lower the rod 4 and insert the lock 6 from the engagement hole b.
The upper end of the is prolapsed (as shown in Figure 2).

Note that when a screwdriver or the like is engaged with the locking portion 14 and the shaft 15 is rotated 90 degrees, the locking portion 1 is inserted into the elongated hole 11.
9 is fitted, and the prevention of the slider 3 from falling is released.

Therefore, it can also be unlocked from outside.

Note that when the rotation operation of the shaft 15 is released, the shaft 15 is rotated back by the spring 16, so that the engaging portion 1 returns to its original state where it fits into the through hole 12 and engages.
9 is restored.

As mentioned above, according to the lock related to this invention,
When the rod is raised together with the slider to lock the door after the door is closed, the spring pushes the shaft back and the locking portion is fitted into the through hole and locked, and the slider is prevented from descending to maintain the locked state; If you push the button again and push in the shaft,
The locking part escapes from the hole and the rod descends together with the slider to unlock the lock. This simplifies the complex structure of converting the rotational movement of the lever into the vertical movement of the rod, and when the button is pressed, the spring is released. The slider can be pushed back downwards and released reliably.

In addition, if a locking part is provided at the end of the shaft and the shaft is rotated 90 degrees using a screwdriver or the like that engages with this locking part, the engaging part will fit into the elongated hole of the slider and the slider will descend. Since the blockage is released, the lock can be unlocked from outside as well.

Furthermore, the spring allows for return rotation to the shaft,
Since the pressing force is applied, the locking portion can be returned to its original position after unlocking from outside, and the locking portion can be automatically fitted into the through hole.
