Description

[Detailed description of the invention] In general, a button-type door lock locks when the door is closed, and is unlocked by pressing the button, and is easy to lock and unlock. Because it is secure, it is often used on various types of doors, but on the other hand, because it is easy to unlock, it is easy for young children to use it on the doors of electrical appliances such as stereos or furniture that are nearby. If you accidentally leave a door open and the door is electrical equipment or furniture that stores comfortable items,
Extremely dangerous.

Therefore, as a result of studies in view of the above circumstances, the present invention proposes a button stop device for a button-type door lock, and one of its purposes is to hold the button 4 in the locked position and open it. The purpose is to prevent danger from stored items by blocking the door and preventing the door from being opened due to mischief by children or the like.

The drawings showing the embodiments of the present invention will be described in detail below.
In Fig. 1, which shows an example of a bush type door lock,
The lock body 3 is fixed to the door 2 which is hinged to the door mounting frame 1 so as to open and close in the direction of arrow a4-a' in the figure, by screwing or fitting, but the same body as shown in the figure, 3 consists of a lock mounting seat 3' which is clamped to the door 2, and a main body 3'' fitted to this, and 4 is a mounting hole 4 drilled in the door 2, which is attached to the door mounting frame 1 side of the main body 3''. A bushing button 6 and a latch 7 are slidably inserted into the storage chamber 5, which is open to the main body.

That is, the latch 7 is provided with a long hole 8 in its length direction, into which the bushing button 6 is inserted, and the cam surface 9 formed at an angle on one side of the bushing button 6 is inserted into the latch 7 . During the pushing operation, one end of the length 718 is connected to the spring 10.
The latch 7 is pushed back against the repulsive force of the door.
The mounting frame 1 is provided with a screw 11 so as to be disengaged from the catch seat 12.

The bush button 6 shown in this figure is formed by rotatably fitting a cap 6b to a button body 6a, and the inner end, which is narrowed by cutting out the cam surface 9, is connected to the lock body. The cap 6b is guided through the through hole 13 drilled in the rear wall of the cap 6b while being prevented from rotating, and an outward flange 14 is provided around the cap 6b at approximately the middle portion thereof, as shown in FIGS. 2 and 3. , the mounting hole 4 has a stepped inner diameter,
It is inserted so that it can be pushed in, slidably and rotated to prevent it from coming off to the outside, and the mounting hole 4 is inserted into the lock body 3
A cylindrical holder 3a is integrally fixed thereto.

Thus, the bushing stopping device provides a protrusion 15 and a guide and stopper groove 16 on the opposing outer and inner wall surfaces of the cap 6b of the bushing button 6 and the mounting hole 4 of the lock body 3 into which it is inserted, so that the cap 6b of the bushing button 6 and the mounting hole 4 of the lock body 3 into which the bushing button 6 is inserted are provided with a protrusion 15 and a guide/stop groove 16 for relative fitting. It is made up of a combination of

That is, the guide/stopper groove 16 is a vertical groove 16 that guides the projection 15 in the pushing direction of the bush button 6.
a, and the longitudinal groove 16a is connected orthogonally to the front end of the longitudinal groove 16a,
The protrusion 15 is formed into a cross-shaped planar shape with a lateral groove 16b guiding the protrusion 15 in the inner circumferential direction.

In the illustrated example, the protrusion 15 is provided on the cap 6b of the bushing button 6, and the guide/stop groove 16 is provided on the inner wall surface of the mounting hole 4'. Guide and stop groove 1 on the inner wall of hole 4
6 may be provided on the cap 6b of the bush button 6,
In this case, the same objectives and effects as described above can be achieved.

Further, the lateral groove 16b has a protrusion 16b' protruding from the side thereof to form a narrow part 16b'', so that the protrusion 15 can be held. If provided, the button 6 can be held in the push-up standing lock position, and it can be easily returned to the push-up standing position. be able to do certain things.

In the above configuration, in the state shown in FIGS. 2 and 4 in which the protrusion 15 is aligned with the longitudinal groove 16a of the guide/stop groove 16, the longitudinal groove 16a freely guides the protrusion 15 in the axial direction. Since the button 6 can be pushed in, the door can be opened in the closed door lock state shown in FIG.
In the state where it is pushed out via latch 7 by 0,
The protrusion 15 is located at the front end of the vertical groove 16a.
In this state, when the cap 6b of the bushing button 6 is rotated into the lateral groove 16b, the protrusion 15 is fitted and guided into the lateral groove 16b.

Therefore, the push button 6 is prevented from being pushed in by the relative fit between the protrusion 15 and the lateral groove 16b, so that the door will not be opened.

Further, when opening the door, by rotating the cap 6b of the bushing button 6 in the opposite direction to that described above, the protrusion 15 is disengaged from the horizontal groove 16b and fitted into the vertical groove 16a, so that the bushing button 6 is rotated in the opposite direction. The bushing operation becomes possible and the door opening operation is executed.

As explained above, according to the button stopper device for a button-type door lock according to the present invention, by rotating the cap 6b of the button button 6, the protrusion 15 and the lateral grooves 16b of the guide/stop grooves 1, . . . The bushing of the bushing button 6 is stopped by relatively fitting them together.

However, by rotating the cap 6b after the door is closed and locked, it is possible to prevent the door from being opened due to mischief by children, etc. Therefore, it is possible to prevent the door from being opened due to mischief by children. Used for locks to prevent accidents caused by them, as well as for caps 6
The button body 6a is provided with a protrusion 15 and a guide-cum-stop groove 16, which are rotatable in the button body 6a. - Provided on the wall surface facing the mounting hole 4 and the cap 6b, which are integrally fitted together so as to
Since the button body 6a is not rotated when the button stop locks and is unlocked, there is no deviation in the relative engagement between the cam surface 9 and the latch 7, and therefore the closing door lock and its unlocking operation are smooth. It has some practical effects.
