DESCRIPTION OF THE PREFERRED EMBODIMENTS The locking and unlocking method according to the present invention will be described below with reference to the embodiments shown in the drawings. FIGS. 1 to 5 are provided to facilitate understanding of the present invention. FIG. 1 shows an earthquake locking and unlocking method for facilitating the understanding of the invention, comprising a device body (3) fixed to a body (1) such as furniture, a cabinet or the like. The device main body (3) supports a locking means (4) movably in the event of an earthquake, and the locking means (4).
Functions as shaking detection means for detecting the 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 has a locking portion (5b) for locking the locking portion (4a) when the locking means (4) moves during an earthquake. . One-way locking means (4)
The elastic means (6) is provided on the return path (the rear ceiling surface in the illustrated example). The operation of the above locking and unlocking method during an earthquake is as follows. That is, in the closed state where the hinged door (2) is closed as shown in FIG. 1, the locking device (5) on the hinged door (2) side is close to the apparatus body (3) on the body (1) side such as furniture and a hanging cabinet. ing. 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). . In this state, the locking part (4a) of the locking means (4) is stopped at the stop part (3a) of the apparatus body (3), and the hinged door (2) is locked at 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 which facilitates the understanding of the present invention. The method has the following features in comparison with the methods shown in FIGS. That is, the magnet (5c) is provided on the locking tool (5), and the locking means (4) (preferably a steel and especially a spring steel or the like having a high strength and elasticity) is moved to the locked position by the swaying force of the earthquake. When the position (Figure 2
To secure 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, in the illustrated one, the incorporation of the magnet catch (7) can be selected. 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). Incorporation of the magnet catch (7) is facilitated, and for example, the incorporation can be selected according to the application. In the illustrated embodiment, for example, a magnet catch (7) is incorporated in the front of the apparatus body (3) in a state of being vertically stacked with a lock mechanism. When there is a magnet catch (7), the hinged door (2) can be stopped to the limit of the attraction force of the magnet catch (7) and locked in a stationary state, so that the locking can be performed more reliably. The attraction plate (8) of the magnet catch (7) (the magnet (7a) and the magnetic plate (7b)) is fixed to the hinged door (2) together with the latch (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) is inclined (5e).
In this way, when the locking means (4) is closed for some reason while the door (2) is in the locked position while the door (2) is open, The locking means (4) is lifted by the inclined surface (5e) and the locking portion (5) is lifted.
It becomes possible to guide to b). Further, as compared with FIG. 5, a magnetic shielding plate (7c) made of a magnetic material such as a steel plate with a slight gap behind the magnetic plate (7b) of the magnet catch (7).
Is attached to the apparatus main body (3) with a size of about the top and bottom and left and right dimensions of the back of the magnet catch (7) or larger. In this way, the magnet catch (7)
Can be prevented from malfunctioning by pulling the locking means (4) (in the case of a magnetic material) by magnetic force. The magnetic shielding plate (7c) is the magnetic plate (7) of the magnet catch (7).
The suction plate (8) has a little gap behind b).
This is because the magnetic force almost becomes the attraction force of the attraction plate (8) when the is attracted (since the line of 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. The method includes inserting a flexible insert (12) as an operating tool for unlocking from a gap of a hinged door (2) to lock a locking means (4). It is to cancel. That is, open the flexible insert (12) and open the door (2).
When it is inserted through the gap of (5), it reaches the locking portion (5b) of the locking tool (5) through the gap between the locking tool (5) and the apparatus main body (3). In this state (with the flexible insert (12) inserted), the flexible insert (12) enters under the locking means (4) by moving the door (2) back and forth (within the range of movement). The locking means (4) is lifted away 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.
As the flexible insert (12), a flexible plastic plate such as polyethylene or polypropylene, a paper plate or the like may be used.

The effects of the method for locking and unlocking during an earthquake according to the present invention are listed below. (1) The locking method in the event of an earthquake according to the present invention is particularly applied to a case in which the locking device is inclined while the locking device is in the locked position while the locking device is open for some reason and the door is closed. It becomes possible to guide the locking means. (2) The method of locking and releasing during an earthquake according to the present invention is particularly effective when the locking means and the locking tool are brought into the locking state where the insertion body can be released by inserting the insertion body through the gap of the opening door. It is certain.
