Abstract

PROBLEM TO BE SOLVED: To actuate a lock even by small swinging and prevent the discharge of a stored object by making a locking condition a lock method different by the size of tremor in on the accurrence of an earthquake by which a locking means of a device main body fixed in a storage body having a hinged door such as furniture and a suspending closet, locks on a locking fixture of the hinged door on the occur rence of an earthquake. SOLUTION: A locking means 14 rollable by the tremor of an earthquake is housed in a recessed place 3b of a device main body 3. The locking means 14 moves to a dashed line position from a continuous line position by the tremor, and becomes a holding condition, and when a hinged door is going to open, and end part of a locking fixture 5 is pinched between the locking means 14 and the ceiling, and brought into a lock condition. In this condition, when it is pulled by strong force not less than a constant value, the locking tool 5 slips out and is released. When large tremor is caused, the hinged door is going to open, on the one hand, the locking means 14 also moves further forward from the holding condition. Therefore, a lock position is a stopping part 3a of the device main body 3, and the locking fixture 5 does not slip out, and the lock condition is not released. Therefore, a lock is actuated even by small tremor, and the discharge of a stored object can be prevented.

[0005]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view showing a locking method for an earthquake according to the present invention; Here, the seismic locking method according to claims 1 to 3 of the present invention is shown in FIGS. 10 to 19, and the seismic locking method according to claim 4 is mainly shown in FIGS. 1 to 9. FIG. 1 shows an earthquake locking device used in the locking method of the present invention. The locking device has a device main body (3) fixed to a main body (1) of a storage unit with a hinged door such as furniture, a hanging cabinet. As shown in FIG. 2, FIG. 3 and FIG.
b) locking means (14) that can be rolled by the tremor of an earthquake
Is accommodated. As the concave portion (3b), for example, a curved surface capable of rolling forward and backward, a spherical surface capable of rolling forward and backward and left and right, and as the locking means (14), for example, a roller, a ball, or the like is used. FIGS. 2, 3 and 5 show the details of the device body (3), but the locking means (14) is provided at the front of the recess (3b).
There is provided a stop (3a) for stopping when is pulled forward. Next, when the locking member (5) is attached to the hinged door (2) and the locking means (14) is moved from the stable position of the recess (3b) by the shake of the earthquake, the hinged door (2) is opened. The locking device (5) is provided with locking means (1).
It is positioned so that it can be locked in 4). The illustrated fastener (5)
Is a mounting part (5) fixed to the hinged door (2) as shown in FIG.
a) and the locking means (1) projecting from the mounting portion (5a).
4) When the hinged door (2) is opened at the position where 4) is moved, the hinged portion (5b) is engaged with the hinged door (2). The illustrated locking member (5) is, for example, a metal plate bent in a substantially L-shape, and has a hole as a locking portion (5b). The illustrated locking portion (5b) does not lock the locking means (14) by passing over the locking means (14) when the locking means (14) is stationary at a stable position. If the locking means (14) moves back and forth, front and rear, left and right, etc. (shown front and rear and left and right), the locking means (14) is raised and locked. . FIG. 5 shows a state in which the hinged door (2) is closed, and the locking means (14) is stationary at the stable position of the recess (3b). On the other hand, the locking member (5) of the hinged door (2) is inserted into the apparatus main body (3) and the locking means (14).
It is inserted and positioned above. In the illustrated embodiment, a roller-shaped guide (3c) is attached to the apparatus main body (3) (and the tip of the locking tool (5) is inclined upward) in order to reliably and smoothly perform the upward positioning. So that it is not locked to the locking means (14) which is stationary. The operation of the locking device during an earthquake according to the locking method described above is as follows. That is, in the closed state where the hinged door (2) is closed as shown in FIG. 5, the latch () on the hinged door (2) side is placed in the device body (3) on the main body (1) side of the storage body with the hinged door such as furniture, a hanging cabinet. 5) is inserted. When an earthquake occurs in this state, the locking means (14) rolls up and moves upward as shown by the alternate long and short dash line in FIGS. 4 and 5, and comes into contact with the locking tool (5) when the hinged door (2) is opened. Position. That is, when the door (2) tries to open as shown in FIG. 6 by swinging simultaneously with the rolling movement of the locking means (14), the locking means (14) is moved to the locking portion (5b) of the locking tool (5). Touched and pulled forward.
The locking means (14) is provided with a stop (3) at the front of the recess (3b).
The locking device (5) and the hinged door (2) are stopped at a), and are opened and stopped at this position (this position is a locked position). The locking means (14) which rolls as described above directly locks the locking tool (5), so that the response speed is extremely fast and a reliable locking operation is achieved. In this locked position, the locking means (14) is vertically held by the elasticity of the apparatus body (3) and the lid (4) (the elastic means is a shape-dependent elastic means) and reduces return resistance (for example, resistance due to friction, dents, etc.). I will receive it. Next, when the hinged door (2) tries to return by swinging back, the locking means (14) receives a return resistance at the locked position, so that the locking part (5b) of the locking tool (5) has the locking means (5b). 1
It returns to the position where it hit 4) and is stopped. That is, in the locked state, the fluttering of the locking member (5) and the hinged door (2) before and after is returned to the locking means (14) and is suppressed compared to the case where there is no resistance. When the earthquake ends, the user pushes the hinged door (2) back with a force greater than its return resistance, and the locking means (14) that has been returned and stopped is returned. As a result, the locking means (14) returns to return to the apparatus body (3).
The locking means (14) is stopped at the stable position of the recess (3b) of the above, and the locking means (14) is in a position where it does not contact the locking portion (5b) of the locking tool (5) and locks when the hinged door (2) is opened. It does not. Therefore, in this state, the hinged door (2) is released from the locking means (14) and can be freely opened without being locked thereto. Next, FIG. 7 shows the main body of the other seismic locking device used in the locking method of the present invention with the lid removed, and the main body (1).
Is the recess (3b) similar to that shown in FIGS.
Is separated left and right so that the locking means (14) does not penetrate into the rear lower surface of the locking tool (5). The feature shown in FIG. 7 is that a guide (3) for guiding the locking device (5) is provided.
c) is not a roller shape but a protrusion to simplify the structure. Further, a method is employed in which two (or more) balls are used as the locking means (14), and if one of the balls is locked during the rolling movement, the lock is secured. Unlocking is performed when the locking device (5) does not lock to any of the balls when two (or more) balls stop at their stable positions (even if they contact slightly, they do not lock). Good). 8 and 9 show another seismic locking device used in the locking method of the present invention. The locking device is a magnet (1) that generates a magnetic force in the direction of the locking position.
0) (a magnetic body such as a steel ball receiving a magnetic force is used as the locking means (14)). That is, the magnet (10) is attached to the apparatus body (3) at the locked position of the locking means (14) (it is in front of the apparatus). Therefore, in the lock operation, the magnetic force of the magnet (10) in the lock position direction is added to the shake of the earthquake. The effect that the locking means (14) is easily moved to the lock position by the magnet (10), thereby increasing the lock sensitivity and making it difficult to be influenced by the noise-like movement is achieved. FIG. 10 shows another locking method according to the present invention. The locking method uses a magnet (1) that generates a magnetic force in the locking position direction.
0) (a magnetic body such as a steel ball receiving a magnetic force is used as the locking means (14)). That is, the magnet (10) is for holding the locking means (14) at the lock position (indicated by a dashed line) (therefore, the magnet (10) is positioned at a position where the locking means (14) becomes the lock position). In the stable position (shown by a solid line) of the locking means (14), the locking tool (5) does not lock to the locking means (14) (it is not necessary to reach locking even if it contacts slightly). As described above. Due to the presence of the magnet (10), the locking operation is such that the magnetic force of the magnet (10) in the lock position direction is added to the shake of the earthquake. Therefore magnet (10)
As a result, the locking sensitivity is increased, and the locking means (14) is held at the locking position. Therefore, once the locking means (14) reaches the locking position, there is no danger of a lock operation error due to the subsequent shaking state or the collision of stored items. When the locking means (14) is moved from the position indicated by the solid line in FIG. 10 to the position indicated by the dashed line and is held there, when the hinged door (2) attempts to open in this state, the locking is performed as shown in FIGS. 11 and 12. The means (14) is locked at the boundary from the deep recess (3b) to the shallow recess (3d) and stops the locking member (5). That is, the locking portion (5b) of the locking tool (5) is locked by the locking means (14), and the end of the locking tool (5) is positioned between the locking means (14) and the device body (3). It is locked when sandwiched by the ceiling. In this locked state, when the hinged door (2) is pulled with a certain force or more, the interposed locking member (5) is released and released. That is, the locked state is not the locked state with a large force but the opened state when the user pulls strongly. Next, when the locking means (14) is held at the position shown by the dashed line in FIG. As shown in FIG. 13 and FIG. 14, while the hinged door (2) is about to open, the locking means (14) also moves further forward from the held position. Therefore, the locking means (14)
Is locked at the stop portion (3a) of the apparatus main body (3). In this locked state, the locking member (5) cannot be released. Therefore, even if the door (2) is pulled with a strong force, the locked state is released. Not done. Therefore, the locking state is different depending on the magnitude of the swing. When the user pulls strongly when the swing is small as described above, the user locks in the open state, and when the swing is small, a large force is not applied. While there is no opening, there is no danger of irrevocability at the end of the earthquake. Compared to this method and the method of locking completely when the fluctuation is small, the former not only eliminates the danger of being unable to release, but also has the advantage that the sensitivity can be increased more easily than the latter. This is because the locking means (14) can be locked with a small force at a position where the movement of the locking means (14) can be moved with a small amount of shaking energy, and can be locked with a strong force at a position where the movement of the locking means (14) is large. Next, the locking tool (5) shown in FIG. 19 can be applied to the locking method of the present invention shown in FIGS. The locking part (5b) of the locking tool (5) has a narrow part in the middle of the locking part (5b).
The movement of 4) is not interrupted (without hindering the locking operation), and the release of the locking means (14) can be made easier by releasing the locking means (14). . Next, FIGS. 15 to 17 show another locking method of the present invention. The locking method does not differ in the locking state depending on the size of the swing, but is another invention. In other words, this is a method of locking the hinged door during an earthquake in which the path from the release position to the lock position and the path from the lock position to the release position are different.
The locking method of the present invention will be described below. The locking method is the same as that of the apparatus main body (3) of FIG.
15 is applied to the bottom surface near the side wall of FIG. 10 instead of the side wall as shown in FIG. 10), and the locking tool (5) shown in FIG. 17 is used. That is, the side (4g) is open on both sides of the lid (4), but the partition (4
e) is provided. In the lid (4), the locking means (1
4) can go to the front end through the central portion and can easily fit into the both sides through the side (4 g) from the front end. Since there is a partition (4e) behind both sides,
The locking means (14) inserted from g) is held back and forth at that position and receives a return resistance. On the other hand, the locking portion (5b) of the locking tool (5) has a concave portion Q which is opened laterally on both sides of the front end P thereof. The partition (4e) is provided on the lid (4) as shown in FIG.
(The position may be around the magnet (10)). That is, in the apparatus of the illustrated embodiment, since the apparatus main body (3) and the lid (4) sandwich the locking means (14) up and down, the apparatus main body (3) and / or the lid (4) are partitioned into one or both. What is necessary is just to provide (4e).
In the illustrated device, the device main body (3) and the lid (4) are locked by a locking means (1).
4), the return resistance is formed due to the elasticity associated with the vertical holding structure. In the case of the earthquake locking method shown in FIGS.
The roller (2) rolls up from the stable position and moves upward to come into contact with the locking member (5) when the hinged door (2) is opened. That is, when the door (2) attempts to open by swinging at the same time as the rolling movement of the locking means (14), the locking means (14).
Is in contact with the front end P of the locking portion (5b) of the locking tool (5), is pulled forward and is further pushed laterally to move. Locking means (1
4) is stopped at the stop (3a) at the front of the recess (3b), and the locking member (5) and the hinged door (2) are opened and stopped at this position. That is, the locking means (14) moves laterally from the front end of the central part and fits into both sides from the side (4g) which is opened. The movement of the locking means (14) is controlled by the locking device (5).
Will fit into the recesses Q on both sides from the front end P of the locking portion (5b). Since there are partitions (4e) behind both sides of the lid (4), the fitted locking means (14) is held back and forth at that position and receives a return resistance.
As a result, the locking means (14) is held in the locked position and the locking tool (5) is locked in the recessed portion Q, so that there is little (albeit slightly) back and forth swinging door (2). Is opened and stopped at this position. FIG. 18 shows another locking method of the present invention. This locking method is a locking method for an opening door which is locked by a plurality of locking means having different releasing methods in the event of an earthquake. That is, one of the two locking means (31) (32) protruding by the spring is pressed by the base (51) of the locking tool (5) when the hinged door (2) is closed, and is released. Is done. The other locking means (32) is not released because it is not pressed by the locking tool (5) when the hinged door (2) is closed. The locking means (32) is pressed and released by the tip (52) of the locking tool (5) by forcibly pulling the hinged door (2). Any locking means (31) (32)
The vibrating body (30) that moves with shaking (the transmission means (33) (3)
4)). The transmission means (33) and (34) enable the locking means (31) and (32) to protrude when a force is applied by a spring (35) and the vibrating body (30) is hit. As apparent from the above, the unlocking method of the hinged door shown in FIG. 18 is different in the unlocking method (one unlocked by closing the hinged door (2) and one unlocked by pulling the hinged door (2) hard). The locking is performed by a plurality of locking means (31) and (32). In the method of locking the hinged door in the event of an earthquake, the locked state is continued by one of the plurality of locking means (31) and (32) having different releasing methods, so that the discharge of the stored items can be prevented reliably.
