DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An earthquake lock device of the present invention which is surely released and an unlocking method thereof will be described with reference to the embodiments shown in the drawings.
Here, in order to facilitate understanding of the earthquake lock device of the present invention, the principle of the lock will be described first. FIG. 1 shows a device for explaining the principle of locking, which device has a device main body (3) fixed to a main body (1) such as furniture or a cabinet. A locking means (4) is supported on the apparatus main body (3) so as to be movable by the sway of the earthquake, and the locking means (4) functions as a sway detecting means for detecting the sway 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 tool (5) is attached to the hinged door (2), and when the locking means (4) is moved by the shaking force of the earthquake, the locking portion (4) is moved.
It has a locking part (5b) for locking a). 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 device for explaining the principle 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. 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 slightly opened by the shaking force as shown in FIG. 3, the locking part (4a) of the locking means (4) is locked to the locking part (5b) of the locking tool (5). To be done. 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 shaking force, the locking means (4) stops at that position. Next, after the earthquake, the user strongly pushes the hinged door (2) to open 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 lock device for explaining the principle, and the lock device has the following features as compared with the device 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. At that time, the position (corresponding to the position in FIG. 2) is held to ensure the operation. Next, the support of the locking means (4) in the device body (3) is supported via the roller R. As described above, when the roller R is used, the frictional force acting on the locking means (4) is greatly reduced and the earthquake detection sensitivity 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, as an important feature of the present invention, the incorporation of the magnetic 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). It is an important feature that the magnet catch (7) can be easily incorporated, and that the magnet catch (7) can be selected depending on the application, for example. In the present invention, for example, a magnetic catch (7)
Is incorporated in the front of the apparatus main body (3) in a state of being vertically stacked with the lock mechanism. When there is a magnetic catch (7), the hinged door (2) can be stopped up to the limit of the attraction force of the magnetic catch (7) and can be locked in a stationary state, so that locking can be performed more reliably. The attraction plate (8) of the magnet catch (7) (magnet (7a) and magnetic plate (7b)) is fixed to the hinged door (2) together with the locking tool (5) on the hinged door (2) side.

FIG. 6 shows an earthquake lock device for explaining the principle. The lock device has the following features as compared with the device shown in FIGS. That is, there is an important feature in that the door stop (9) such as rubber, spring, and elastic material is incorporated in the device itself. The door stop (9) is attached to the locking tool (5) on the side of the hinged door (2) in the illustrated embodiment, and abuts against the front of the device body (3) on the body (1) side such as furniture or a hanging cabinet. The shock absorber function of the dovetail door (2) and the closing position determining function are also provided. In this way, when the locking device itself at the time of the earthquake has the closing positioning function, the locking mechanism exerts a very important effect that the positioning of the lock is ensured. FIG. 7 shows an earthquake lock device for explaining the principle, and the lock device has the following features as compared with the device shown in FIGS. That is, there is an important feature in that the earthquake locking device is mounted at a position away from the free end of the hinged door (2) to the hinge side. When installed on the free end of the hinged door (2), the hinged door (2) moves far from the hinge (particularly when the hinged with spring is used to secure the closing force of the hinged door (2) without using a magnet catch). This is because there is a case where the lock mechanism becomes most unstable for the lock mechanism. When the locking device for an earthquake is mounted at a position away from the free end of the hinged door (2) toward the hinge side, the movement of the hinged door (2) is reduced, so that the lock mechanism is securely locked. This is a very important effect of securing the lock if you want to reduce costs without a magnet catch. FIG. 8 shows an earthquake lock device for explaining the principle, and the lock device has the following features as compared with the device shown in FIGS. That is, the locking means (4) has a bent locking portion (4
The end portion that does not have a) and extends from the main body (4b) functions as the locking portion (4a). Further, the rear end of the storage chamber (for accommodating the locking means (4)) of the apparatus body (3) is made into an inclined surface (3g) so that it does not rebound when the locking means (4) returns. If the locking means (4) does not have the bent locking portion (4a), the locking width of the locking portion (5b) provided on the locking tool (5) is substantially increased, and the magnet is magnetized. There is a feature that the door (2) having only the hinge with spring without using the catch has a margin and locks even if the door (2) slightly starts opening and closing at the start of the earthquake.
FIG. 9 shows an earthquake lock device for explaining the principle, and the lock device has the following features as compared with the device shown in FIGS. That is, the attachment of the locking member (5) to the hinged door (2) is performed not at the upper part but at the mounting part (5a) bent downward, so that the projecting dimension of the locking member (5) is reduced. It is possible to reduce it. FIG. 10 shows an earthquake lock device for explaining the principle, and the lock device has the following features as compared with the device 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). 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. By doing so, it is possible to prevent the magnetic catch (7) from pulling the locking means (4) (in the case of a magnetic body) with a magnetic force to cause a malfunction. Magnetic shielding plate (7c)
Has a small gap rearward from the magnetic plate (7b) of the magnet catch (7) because most of the magnetic force when the adsorption plate (8) is adsorbed becomes the adsorption force of the adsorption plate (8). This is because the influence on the magnet catching force is small because it passes through the attraction plate (8).

FIGS. 11 and 12 show an earthquake lock device for explaining the principle, and the lock device has the following features as compared with the device shown in FIGS. 1 to 10. That is, instead of the magnetic catch (7) incorporated in the earthquake lock device of FIG. 5, incorporation of mechanical resistance catching means can be selected. That is, the engagement body (5f) (however, it may be a separate body from the engagement tool (5)) is provided at the upper end of the engagement tool (5), and when the hinged door (2) is closed, the spring ( 10) It serves as a catching means of mechanical resistance that engages with (supported by the spring support (3h)) and holds the closed state of the hinged door (2). Ie spring (10)
The closed state of the hinged door (2) is maintained by the spring force and the frictional force of (1) and the same function as the magnetic catch (7) (FIG. 5) is exerted. FIG. 13 shows an earthquake lock device and its releasing method according to the present invention. In the releasing method, a flexible insertion body (12) is inserted as an operation tool for releasing through a gap of a hinged door (2) and locking means ( 4) is canceled. That is, if the flexible insert body (12) is inserted through the gap between the hinged doors (2), it passes through the gap between the locking tool (5) and the apparatus main body (3) and reaches the locking portion (5b) of the locking tool (5). It In this state (with the flexible insert (12) inserted), the flexible door (1) is moved by moving the hinged door (2) back and forth (within the range of movement).
2) enters below the locking means (4) and lifts the locking means (4) away from the attraction force of the magnet (5c).
As a result, the locking means (4) is in the release position, and the locking device is released during the earthquake. Flexible insert (12)
As the material, a flexible plastic plate such as polyethylene or polypropylene, or a paper plate may be used. 14 and 15
Shows another seismic locking device of the present invention and its releasing method, which uses a rigid insert (70) as an operating tool for releasing. That is, the operation end of the rigid insert body (70) is inserted through the upper and lower gaps between the hinged door (60) and the main body (91). In this state (for example, when the door is inserted sideways from the side end of the hinged door (60) along the upper and lower gaps to reach this state), the release movement transmitting means (50).
The lock is released by pushing (the lever or the like to transmit the movement to the locking means (4)). The release movement transmitting means (50) is used when the locking means (4) cannot be directly moved, and is not necessary when it can be directly moved. The rigid insert (70) is made of a steel rod, a stainless steel rod, etc., and its operating end is larger than a right angle (preferably about 95 ° to 120 °) (more preferably about 10 °).
It can be bent (0 ° to 110 °) to be applied to narrow gaps. FIG. 15 shows that the other end of the essential operation end bent more than the right angle is accompanied by another operation end of a substantially right angle. The other operation end having a substantially right angle has an advantage of easily inserting into the upper and lower gaps between the hinged door (60) and the main body (91) for releasing the hinged door (60) having a structure without a door contact surface.
