BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a method for locking and releasing an earthquake according to the present invention. FIG. 1 shows an earthquake locking and unlocking method according to the invention, comprising a device body (3) fixed to a body (1), such as furniture, a cabinet or the like. The device body (3) has a locking means (4) movably in case of an earthquake.
Are supported, and the locking means (4) functions as a shaking detecting means for detecting a shaking force of the earthquake. The locking means (4) has a locking portion (4a) and is stopped at a stopping portion (3a) of the apparatus body (3). Next, a locking member (5) is attached to the hinged door (2), and the locking portion (4a) is locked when the locking means (4) moves during an earthquake.
b). On the other hand, an elastic means (6) is provided on the return path (the rear ceiling surface in the illustrated embodiment) of the locking means (4). The operation of the locking and unlocking method during an earthquake according to the present invention shown in the above embodiment is as follows. That is, the hinged door (2)
However, in a closed state as shown in FIG. 1, the locking device (5) on the door (2) side is close to the device main body (3) on the main body (1) side such as furniture and a hanging cabinet. When an earthquake occurs in this state, the locking means (4) moves and comes into contact with the locking tool (5) as shown in FIG. When the swing door (2) is further opened slightly as shown in FIG. 3, the locking portion (4a) of the locking means (4) is locked to the locking portion (5b) of the locking tool (5). . The movement of the locking means (4) leading to locking is ensured not only by swinging but also assisted by gravity and the magnetic force of the magnet (5c) of the locking tool (5). In this state, the locking part (4a) of the locking means (4) is stopped at the stop part (3a) of the apparatus main body (3) and the hinged door (2).
Is locked in that position. Naturally, the swaying force also acts in the direction of closing the hinged door (2), but the locking means (4) is pressed by the elastic means (6) of the apparatus body (3) in the locked position. Since the pressing force of the elastic means (6) is set to be larger than the swinging force, the locking means (4) stops at that position. Next, when the earthquake is over, to open the hinged door (2), the user strongly pushes the hinged door (2). As a result, as shown in FIG. 4, when the elastic means (6) retreats and retreats by a certain amount or more, the pressing by the elastic means (6) is released. As a result, the locking means (4) returns from the state of FIG. 4 to the initial state of FIG. 1 by inertia.

FIG. 5 shows an earthquake locking and unlocking method according to the present invention, which has the following features as compared with the methods shown in FIGS. That is, the magnet (5c) is attached to the locking member (5).
When the locking means (4) (preferably steel and, in particular, spring steel or the like having strength and elasticity) is moved to the locked position by the swaying force of the earthquake, its position (corresponding to the position in FIG. 2) To ensure operation. Next, the support of the locking means (4) in the apparatus main body (3) is supported via rollers R. When the roller R is used in this manner, the frictional force acting on the locking means (4) is greatly reduced, and the sensitivity for detecting earthquakes is improved.
Next, a coil spring is provided as the elastic means (6) in the front-rear direction (having a vertical inclination), and the lower edge of the front end of the coil spring retreats with the retraction of the locking means (4) and is locked at a predetermined retreat position. To enable the locking means (4) to return to the initial state. Next, a feature of the present invention is a magnet catch (7).
Has been made selectable. That is, the magnet catch (7) can be easily incorporated into the apparatus main body (3) by a shaft or the like, and can be used without the magnet catch (7). The feature is that the magnet catch (7) can be easily incorporated, and the installation can be selected, for example, according to the application. In the present invention, for example, the magnet catch (7) is incorporated in the front of the apparatus body (3) in a state of being vertically stacked with a lock mechanism. Door with magnet catch (7) (2)
Can be locked to the limit of the attraction force of the magnet catch (7) and locked in a stationary state, so that locking can be performed more reliably. Magnet catch (7) (Magnet (7
a) and the suction plate (8) of the magnetic plate (7b)) are fixed to the hinged door (2) together with the locking member (5) on the hinged door (2) side. FIG. 6 shows an earthquake locking and unlocking method according to the present invention, which has the following features as compared with the apparatus shown in FIGS. That is, the upper end of the locking tool (5) has an inclined surface (5e). In this case, the locking means (4) is locked even if the hinged door (2) is open for some reason. When the hinged door (2) is being closed in this state, the locking means (4) can be lifted up on the inclined surface (5e) and guided to the locking portion (5b). That is, the projecting force of the locking means (4) is such that the projecting force is easily pushed back on the inclined surface (5e) when the hinged door (2) is closed. In other words, a lock (5) is used which can push back the protrusion of the locking means (4) when the hinged door (2) is closed. Further, as compared with FIG. 5, a magnetic shielding plate (7c) made of a magnetic material such as a steel plate has a slight gap behind the magnetic plate (7b) of the magnet catch (7), It is attached to the apparatus main body (3) with a size about the right and left dimensions or larger. In this case, the magnet catch (7) is locked by the locking means (4).
It is possible to prevent (in the case of a magnetic body) from being pulled by magnetic force and malfunctioning. The magnetic shielding plate (7c) has a little gap behind the magnetic plate (7b) of the magnet catch (7) because the magnetic force is almost the same as that of the attracting plate (8) when the attracting plate (8) is attracted. This is because the magnetic force becomes an attraction force (since the magnetic force passes through the attraction plate (8)), and the influence on the magnet catching force becomes small. FIG. 7 shows an earthquake locking and unlocking method according to the present invention, which inserts a flexible insert (12) as an operating tool for unlocking from a gap of a hinged door (2) and locks a locking means (4). It is to cancel. That is, if the flexible insertion body (12) is inserted through the gap of the opening door (2), the flexible insertion body (12) passes through the gap between the locking tool (5) and the apparatus body (3) and reaches the locking portion (5b) of the locking tool (5). You. In this state (in a state where the flexible insert (12) is inserted), the hinged door (2) is moved back and forth (within the range of movement) to thereby make the flexible insert (12) flexible.
Are moved under the locking means (4) to lift the locking means (4) apart from the attraction force of the magnet (5c). As a result, the locking means (4) is in the release position, and the locking and releasing method during an earthquake is released. Flexible insert (1
As 2), a flexible plastic plate such as polyethylene or polypropylene, a paper plate, or the like may be used. As is clear from the above, the projection output of the locking means (4) can be easily returned (even with the inclined surface (5e) of the locking tool (5) or the flexible insert (12)). That's it. 1 to 5
It is clear from the drawings that the locking and unlocking method during an earthquake is the same as the configuration of the locking and unlocking method during an earthquake in FIGS. 6 and 7. Therefore, even in the method of locking and releasing in the event of an earthquake shown in FIGS.

[0007]

The effects of the method for locking and unlocking during an earthquake according to the present invention are listed below. (1) In the locking and releasing method in the event of an earthquake according to the present invention, in particular, the releasing can be surely performed because the projecting output of the locking means can be easily returned. (2) The locking and unlocking method according to the present invention, in particular, makes it possible to easily return the projecting power of the locking means so that the locking means may be closed when the hinged door is closed depending on the hinged door to which the locking and unlocking during earthquake is applied. Can be pushed back.
