BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a method for releasing a locking device during an earthquake according to the present invention. FIG. 1 shows an earthquake locking device to which the unlocking method of the present invention is applied, and the locking device has a device main body (3) fixed to a main body (1) such as furniture or a cabinet for hanging. An elastic material (15) is interposed between the main body (1) and the hinged door (2) to seal the hinged door (2) in a state where the hinged door (2) is closed and to close the hinged door (2) to its closed position. It can be pushed a little from. Next, a locking means (4) is supported in the apparatus main body (3) so as to be movable by the swaying force of the earthquake. It is desirable from the standpoint of earthquake detection sensitivity that the locking means (4) can be moved by a swinging force before and after the earthquake. Further, as the locking means (4), in addition to an obstacle that slides and moves as shown in the drawing (which may be supported by rollers to facilitate movement), a swing detecting means supported by a pendulum, a sphere, and a spring; What is necessary is just to detect the shake of the earthquake such as a moving obstacle. The locking means (4) has a locking portion (4a) and the device body (3) (the stopping portion (3a)).
, The withdrawal of a certain amount or more is stopped. Next, a locking member (5) is attached to the hinged door (2), and the locking portion (4a) is locked when the locking means (4) is moved forward by the force of the earthquake. Part (5b).
On the other hand, an elastic means (6) is provided on the return path of the locking means (4) moved forward. The operation of the method for releasing the locking device during an earthquake according to the present invention shown in the above embodiment 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. The locking means (4) supported in the apparatus main body (3) is at the position indicated by the dashed line in FIG. When an earthquake occurs in this state, the shaking of the earthquake is detected as shown by the solid line in FIG. 1 and the locking means (4) moves to move the locking portion (4a) 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 in the locked position, the locking means (4) is engaged with the device body (3).
(6). 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. Here, the present invention relates to a method for releasing a hinged door (2) after an earthquake, wherein an elastic member (1) is provided between the door and a main body (1) such as furniture or a suspended cabinet.
5) is a method for releasing the interposed swing door. That is, to open the hinged door (2) after the earthquake, the user pushes the hinged door (2) strongly with the compression of the elastic material (15) while resisting the pressing force of the elastic means (6). As a result, as shown in FIG. 2, the elastic means (6) retreats, and when the elastic means (6) retreats beyond a certain level, the pressing by the elastic means (6) is released. As a result, the locking means (4) returns from the state shown in FIG. 2 to the initial state shown by the dashed line in FIG. 1 due to inertia.

FIG. 3 shows another seismic locking device to which the releasing method of the present invention is applied, and the locking device is shown in FIGS. 1 and 2.
Has the following features as compared with those shown in FIG. 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 strength and elasticity) is moved to the locked position by the swaying force of the earthquake. At this time, the position (corresponding to the position indicated by the solid line in FIG. 1 of the above-described embodiment) is held to ensure the 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 in an anteroposterior direction with an inclination as an elastic means (6), and the lower end of the front end of the coil spring retreats with the retraction of the locking means (4) to return the locking means (4) to the initial state. Is easy.

FIG. 4 shows another seismic locking device to which the releasing method of the present invention is applied, and the locking device is provided with locking means (1).
As 4), a steel ball is used. That is, when an earthquake occurs from the closed state of the hinged door (2) in FIG. 4 (the locking means (14) is in the position of the dashed line), the locking means (14) moves forward and falls as shown by the solid line in FIG. (By gravity) to the locking part (5b) of the locking tool (5). That is, the locking means (1
4) is movably supported by the apparatus main body (3), moves by the action of gravity, and is locked by the locking member (5). ). This state is a locked state, and the locking means (14) is a stop portion (3a) of the apparatus body (3) (a cross-shaped groove when viewed from the front)
And the hinged door (2) is locked at that position. Even if a swinging force acts in the direction to close the hinged door (2), the locking means (14) is pressed by the elastic means (6) of the apparatus body (3) in the locked position, and the hinged door (2) does not move any more.
Next, when the earthquake ends and the hinged door (2) is opened, the user pushes the hinged door (2) strongly against the pressing force of the elastic means (6) and with the compression of the elastic material (15). As a result, FIG.
As shown in (1), when the elastic means (6) retreats and retreats beyond a certain level, the pressing by the elastic means (6) is released. As a result, the locking means (14) returns from the state shown in FIG. 5 to the initial state shown by the dashed line in FIG. 4 due to inertia.

FIG. 6 shows a releasing method (not the present invention) for better understanding as compared with the present invention, and a locking device according to the releasing method is provided between a main body (1) such as furniture and a cabinet. It has a hinged door (2) which is closed with a front-rear gap S by an elastic stopper means separate from the device (for example, a well-known magnet having a resilient catch characteristic may be used, not shown). Therefore, when the hinged door (2) is closed, the hinged door (2) can be slightly pushed from its closed position. Except for the differences described above, the configuration, operation, and release method of the device body (3), the locking means (4), the locking tool (5) of the hinged door (2), the elastic means (6), etc. are shown in FIG. It is the same as the one described above, and the description is omitted.

[0009]

The embodiment of the method for releasing the locking device at the time of earthquake according to the present invention is as described above, and the effect thereof will be described below. Since the method for releasing the locking device in the event of an earthquake according to the present invention is a release method in which the movement in the closing direction of the hinged door is directly transmitted from the locking tool to the locking means, a new member other than the locking means for release is unnecessary. The configuration is simple.
