BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a locking device for an earthquake according to an embodiment of the present invention.
Here, the principle of the lock will be described first to facilitate understanding of the earthquake lock device of the present invention. 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 member (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 provided.
a) has a locking portion (5b) for locking. 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. Further, as shown in FIG. 3, when the swing door (2) is slightly opened by the swinging force, the locking portion (4a) of the locking means (4) is locked to the locking portion (5b) of the locking tool (5). Is 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 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 device for explaining the principle. The locking device has the following features as compared with the devices 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 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, as an important feature of the present invention, the incorporation of the magnet catch (7) is 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). 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 magnet catch (7)
Is mounted on 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 a seismic locking device for explaining the principle. The locking device has the following features as compared with the devices 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. In the illustrated embodiment, the door stop (9) is attached to the latch (5) on the hinged door (2) side and abuts against the front of the apparatus main body (3) on the main body (1) side such as furniture and a hanging cabinet. In addition to the buffering function of the dovetail door (2), it also bears the closing positioning function. 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 locking device for explaining the principle. The locking device has the following features as compared with the devices 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 locking device for explaining the principle. The locking device has the following features as compared with the devices shown in FIGS. That is, the locking means (4) is provided with the bent locking portion (4).
The end extending from the main body (4b) without a) functions as the locking portion (4a). Further, the rear end of the storage chamber (for storing the locking means (4)) of the apparatus main body (3) is formed with 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 locking device for explaining the principle. The locking device has the following features as compared with the devices 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 locking device for explaining the principle. The locking device has the following features as compared with the devices shown in FIGS. That is, the upper end of the locking tool (5) is formed as an inclined surface (5e). In this case, the locking means (4) is locked at the locking position even if the hinged door (2) is open for some reason. When the hinged door (2) is being closed in the state described above, the locking means (4) can be lifted by 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 of about right and left dimensions or larger. In this way, it is possible to prevent the magnet catch (7) from erroneously operating by pulling the locking means (4) (in the case of a magnetic material) by the magnetic force. Magnetic shielding plate (7c)
Has a slight gap behind the magnetic plate (7b) of the magnet catch (7) because the magnetic force almost becomes the attraction force of the attraction plate (8) when the attraction plate (8) is attracted (the line of magnetic force is This is because the influence on the magnet catching force becomes small (because it passes through the suction plate (8)).

FIGS. 11 and 12 show a seismic locking device for explaining the principle. The locking device has the following features as compared with the devices shown in FIGS. In other words, instead of the magnet catch (7) incorporated in the locking device in the event of an earthquake in FIG. 5, the incorporation of catch means of mechanical resistance can be selected. That is, an engaging body (5f) (but may be separate from the locking tool (5)) is provided at the upper end of the locking tool (5), and when the hinged door (2) is closed, the spring ( 10) It is a catch means of mechanical resistance which engages with (supported by the spring support (3h)) and keeps the door (2) closed. That is, the spring (10)
With the spring force and frictional force of the above, the closed state of the door (2) is maintained, and the same function as the magnet catch (7) (FIG. 5) is exerted. FIG. 13 shows an earthquake locking device and a method for releasing the same according to the present invention. In the releasing method, a flexible insert (12) is inserted as an operating tool for release from a gap of a hinged door (2) and a locking means ( 4) is canceled. 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 (with the flexible insert (12) inserted), the hinged door (2) is moved back and forth (within the range of movement) to allow the flexible insert (1) to move.
2) is to go under the locking means (4) and 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 device in the event of an earthquake is released. Flexible insert (12)
For example, a flexible plastic plate such as polyethylene or polypropylene, a paper plate, or the like may be used. 14 and 15
Fig. 3 shows another earthquake locking device and a method of releasing the same according to the present invention, which uses a rigid insert (70) as an operating tool for releasing. That is, the rigid insertion body (70) has an operation end inserted through upper and lower gaps between the hinged door (60) and the main body (91). In this state (for example, the state is inserted laterally from the side end of the hinged door (60) along the upper and lower gaps and reaches this state), the release motion transmitting means (50)
The lock is released by pushing (a lever or the like that transmits 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 unnecessary when it can be directly moved. The rigid insert (70) is made of steel rod, stainless steel rod, etc., and its operating end is larger than a right angle (preferably about 95 ° to 120 °) (more preferably about 10 °).
It is bent (from 0 ° to 110 °) so that it can be applied to a narrow gap. FIG. 15 shows an essential operating end bent at a greater angle than the right angle, with another operating end substantially at a right angle attached to the other end. The other operation end having a substantially right angle has an advantage that it can be easily inserted into the upper and lower gaps between the hinged door (60) and the main body (91) for releasing the hinged door (60) having no door stop surface.
