Abstract

PROBLEM TO BE SOLVED: To enhance earthquake-detection sensitivity and facilitate the releasing of a lock by slipping off a rolling means housed on an inclined face by shaking force, locking a locking means which has been stopped in its motion on the locking tool of a hinged door and possessing a slight gap in the direction where a locking state is opened to stop opening. SOLUTION: In the case where the resistance of a releasing means is set large, a hinged door 91 is returned and stopped on the edge part 6a of a releasing means 6 for the motion of the direction for closing the hinged door every wave of the shock of an earthquake. After the earthquake, when the hinged door 91 is pressed from a state where it has a gap and opens and stops, the edge part 6a of the releasing means 6 pushes up the locking part 3b of a locking means 3. The pushing-up is smoothly performed by rotating the releasing means 6 by centering the base part. When the locking means is pushed up at a constant distance or longer, the locking means 3 is returned in a state where motion (fall) is stopped since a rolling means 4 enters the stopper 3a of the locking means 3 in accordance with an inclined face 2b.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view showing a locking method for an earthquake according to the present invention; 1 to 3 show a locking method of the present invention and a locking device for an opening door which is embodied by the method according to the present invention,
The lock device has a device main body (1) fixed to a main body (90) of a storage body with a hinged door such as furniture, a hanging cabinet. The device body (1) has an inclined surface (2b) inclined toward the locking means (3) (described later). Illustrated body (90)
Although the plane shape of the inclined surface (2b) is circular, the position of the locking means (3) is eccentric from the center of the circle because the locking means (3) can be disposed in front and the whole is made smaller. Because you can do it. However, the inclined surface (2) of the main body (90)
The planar shape of b) does not have to be circular, and the position of the locking means (3) does not have to be eccentric. The locking means (3) is movably provided on the apparatus main body (1), and the locking means (3) shown in the figure is a pillar-shaped one that moves linearly and moves downward by gravity. Linearly moving locking means (3),
Includes those that rotate, those that move downward, those that move upward, and those that move laterally. Further, the locking means (3) includes one that moves by gravity, one that moves by spring force, one that moves by magnetic force, one that moves by a plurality of these forces, and the like. The locking means (3) is stopped at its stopper (3a) by a rolling means (4) such as a ball or a roller. The rolling means (4) is desirably one ball for simplicity of the structure.
Is shown to stop moving. However, the stopper (3
Rolling means (4) that stops and moves the locking means (3) by, for example, a magnetic force without hitting a). That is, when the rolling means (4) abuts or approaches, the locking means (3) stops moving (stops trying to move by gravity, spring force, magnetic force, etc.). The locking portion (3b) of the locking means (3) is in the form of a flange in the illustrated embodiment, but has a hook shape.
It may be a simple columnar shape or the like. Further, the apparatus main body (1) has a lid (2c) in the illustrated embodiment to facilitate handling up to assembly and installation. Next, the hinged door (9
A locking tool (5) fixed to 1) is provided, and the locking tool (5) has a locking tool main part (5a) positioned to face the locking means (3). In the illustrated embodiment, a release means (6) is movably provided on the main part (5a) of the locking member so as to be inclined from back to front and receive the force of a spring (7). The releasing means (6) is made movable with respect to the locking tool main part (5a) in order to enable smooth releasing of the locking means (3). Therefore, the movement includes a movement that does not receive the force of the spring (7), a movement that moves linearly, a rotation, a bending movement of an inclined leaf spring, and an expansion and contraction movement of a coil spring. . The release means (6) shown is provided with a tip (6) for grasping the locking means (3).
a) is V-shaped and its base (6b) is
a) is attached so as to be able to move both forward and backward and rotate. The operation of the locking method of the present invention shown in the above embodiment and the locking device of the hinged door in case of earthquake which embodies the method is as follows. That is, FIG. 1 shows a standby state of the lock device of the present invention, in which the locking means (3) is at rest in a raised state. The stopper (3a) of the locking means (3) hits the rolling means (4) to stop the movement of the locking means (3) (stop moving downward by gravity). In the state where the rolling means (4) stops moving the locking means (3), the center of the rolling means (4) is a stopper (3a) as shown in the figure.
If the state is shifted outward from the end of, the earthquake detection sensitivity is improved. This is because the rolling means (4) easily comes off the stopper (3a) by the swaying force during the earthquake. In the state shown in FIG. 1, the lock (5) of the hinged door (91) does not hit the locking means (3), so that the hinged door (91) can be freely opened and closed. Next, during an earthquake, the rolling means (4) moves against the inclined surface (2b) as shown by the dashed line in FIG. As a result, the rolling means (4) comes off the stopper (3a), and the locking means (3) moves by gravity. That is, the locking means (3) falls to the locking tool (5), while the hinged door (91) tries to open with a swinging force. As a result, as shown in FIG. 4, the locking portion (3b) of the locking means (3) is provided with the locking tool (5).
Between the leading end of the main part (5a) and the leading end (6a) of the releasing means (6). In this state, the door (9
The movement in the opening direction of 1) is as shown in FIG.
Stop at the tip of a). On the other hand, with respect to the movement of the hinged door (91) in the closing direction, the movement is different between the case where the resistance of the release means (6) is set large and the case where the resistance is set small. However, when the hinged door (91) stops opening, it is common that the hinged door (91) has a slight gap in the opening direction. First, when the resistance of the release means (6) is set to be large, as shown in FIG. 5, the door (91) is released from the movement of the door (91) in the closing direction for each wave of the earthquake. At the tip (6a) of the motor. That is, the hinged door (91) is opened and stopped with a slight gap, and the discharge of the stored items from the main body (90) of the storage body with the hinged door is prevented. Next, when the earthquake ends, the user pushes the hinged door (91) from the stopped state with the gap shown in FIG. Thereby, the tip part (6a) of the releasing means (6) pushes up the locking part (3b) of the locking means (3). The lifting means (6) pushes up the locking means (3) by its base (6).
By rotating around b), the operation is performed smoothly. In the case where the release means (6) is also made movable forward and backward as in the illustrated embodiment, the shock applied to the locking means (3) at the time of release is absorbed and mitigated by the advance and retreat. Since the locking means (3) is pushed up by a certain amount or more, the sliding means (4) enters the stopper (3a) of the locking means (3) according to the inclined surface (2b) as shown in FIG. 3) returns to the state of FIG. 1 in which the movement (fall) is stopped. Next, when the resistance of the release means (6) is set to be small, the door (91) is not limited to the state shown in FIG. 5 in response to the movement of the door (91) in the closing direction for each wave of the earthquake.
1 through FIG. 6 to FIG. That is, the movement from FIG. 1 to FIG. 4 and the movement from FIG. 4 to FIG. 6 to FIG. 1 are repeated for each wave of the earthquake. The hinged door (91) repeatedly flutters during the earthquake, but does not open. FIGS. 7 to 9 show another locking method of the present invention and an embodiment of a hinged locking device for a hinged door, in which the locking means (3) is shortened, so that the device body (1) is also reduced. The top and bottom are thin. Furthermore, the height of the leading end of the locking tool main portion (5a) of the locking tool (5) is increased to enable reliable locking even when the opening speed of the hinged door (91) is high. FIG. 10 shows the locking device of FIGS. 7 to 9 in which a digging (93) is provided in the top plate of the main body (90), and is fitted and fixed in the digging (93). The protrusion dimension is shortened, and the position of the locking tool (5) can be set high. Therefore, the locking member (5) can be attached even in the case where there is a limit in the dimensions that can be attached, as in the case of the hinged door (91) with glass (92).
