Description

  The present invention prevents furniture doors or drawers such as chests, cupboards, bookshelves, etc. from opening suddenly due to the impact in the event of an earthquake, and can operate against extremely small earthquake shaking. The present invention relates to an earthquake response tool suitable for long-period vibration.

  Conventionally, furniture that has a door that swings and opens horizontally such as a chiffon, cupboard, book shelf, etc., during a earthquake, the door or drawer suddenly opens due to the shock of the vibration, and the stored items pop out to the outside This is a secondary disaster that puts people at risk. Various earthquake-resistant devices have been developed for preventing furniture doors (drawers) from opening suddenly due to such an impact caused by an earthquake.

  Among such earthquake-resistant devices, there are various types that utilize the rolling of a sphere due to an impact during an earthquake. This is because the sphere in a stationary state rolls by detecting the vibration at the time of the earthquake, and the actuated member incorporated in the earthquake resistant device moves following the movement of the sphere by the movement due to the rolling. It is set and the actuated member is locked with the locking member mounted on the furniture door. As a result, the furniture door can be locked in a closed state, and a situation in which the door suddenly opens during an earthquake can be prevented.

As such an earthquake-resistant device, for example, there is one as shown in Patent Document 1 below. This is because a spherical body is accommodated in the case, and a movable body that can move up and down is provided in the case, and the spherical body moves while rotating in the direction of the movable body against the shaking of the earthquake, and hits the movable body. The moving body is moved downward to operate the operating body that follows the moving body, and the hook of the operating body is locked to the locked member formed on the door. This prevents the opening. As described above, many of the basic structures of the earthquake-resistant device using the sphere use the movement of the sphere as described above.

  By the way, the occurrence of relatively large earthquakes has increased in recent years. In addition, high-rise buildings are increasing in condominiums, apartments, and commercial facilities. Such a high-rise building has a structure that tends to cause long-period vibration due to a large earthquake. And when a long-period vibration due to an earthquake occurs in such a high-rise building, large and slow shaking will continue for a long time.

  In the conventional type earthquake response tool as disclosed in Patent Document 1 described above, the movement of the sphere is slow with respect to such a long-period vibration. Therefore, the operation of the sphere for maintaining the locked state of the operated member of the earthquake countermeasure tool and the locking member mounted on the furniture door (drawer) is difficult to occur. That is, the conventional type earthquake response tool is not suitable for long-period vibration. A technical problem (object) to be solved by the present invention is to provide an earthquake response tool that has an extremely simple structure and can sufficiently cope with long-period vibration caused by an earthquake.

  In view of the above, the inventors have intensively and researched to solve the above-described problems. As a result, the inventor of the invention of claim 1 includes a housing provided with an inner chamber having two small chambers partitioned by a partition portion, and the inner chamber. Two spheres, a receiving surface recessed in a flat spherical shape from the outer periphery toward the central portion on the lower surface side, and a sensing portion that swingably fits in the inner chamber and projects outward from the sensing portion And a swinging hook member comprising a hook lever portion formed with a hook piece at the tip, and a cover material covering the opening of the inner chamber of the housing, the swinging hook member having a lower surface side of the tip portion And a swinging projection formed in one of the inner chambers of the housing and a swinging support portion into which the swinging projection is inserted on the other. Solved the problem.

  According to a second aspect of the present invention, in the earthquake response tool according to the first aspect, the swing protrusion is formed on the lower surface side of the tip portion of the sensing portion, and the swing support portion is formed on the housing side. The above-mentioned problem was solved by using an earthquake response tool. According to a third aspect of the present invention, in the earthquake response tool according to the first aspect, the swing support portion is formed on the lower surface side of the tip portion of the sensing portion, and the swing protrusion is formed on the housing side. The above-mentioned problem was solved by using an earthquake response tool.

  According to a fourth aspect of the present invention, in the earthquake response tool according to any one of the first, second, and third aspects, a holding recess is formed on the upper surface side of the swing hook member and is held on the lower surface side of the cover material. The above-mentioned problem has been solved by providing an earthquake countermeasure tool in which a convex portion is formed and the holding convex portion is loosely inserted into the holding concave portion in a state where the cover member is mounted on the casing.

  According to a fifth aspect of the present invention, in the earthquake response tool according to any one of the first, second, and third aspects, a holding convex portion is formed on the upper surface side of the swing hook member, and the lower surface side of the cover material. The above-described problem has been solved by providing an earthquake countermeasure tool in which a holding recess is formed, and the holding projection is loosely inserted into the holding recess in a state where the cover member is mounted on the housing.

  The invention according to claim 6 is the earthquake response tool according to any one of claims 1, 2, 3, 4 or 5, wherein the partition portion is formed along a width direction of the casing and The above-mentioned problem has been solved by using an earthquake response tool configured to partition the inner chamber into a front small chamber and a rear small chamber along the front-rear direction.

  The invention according to claim 7 is the earthquake response tool according to any one of claims 1, 2, 3, 4 or 5, wherein the partition portion is formed along the front-rear direction of the casing, The said subject was solved by setting it as the earthquake response tool comprised as a structure which partitions the said inner chamber into a left chamber and a right chamber along the width direction. According to an eighth aspect of the present invention, in the earthquake response tool according to any one of the first, second, third, fourth, and fifth aspects, the partition portion is formed along a diagonal direction of the inner chamber and the The above-mentioned problem is solved by using an earthquake response tool configured to partition the inner chamber into two triangular left and right chambers along the width direction.

  In the first aspect of the invention, the inner chamber of the housing is partitioned by the partition portion to form two small chambers, and the two spheres are arranged one by one in each of the two small chambers. . Each of the two small chambers of the housing has a single sphere, so that when an earthquake occurs, the two spheres move independently from each other without interfering with each other, and the swing hook member is secured. Can be operated. Therefore, even if some trouble occurs and the movement of the sphere is not performed at the time of the occurrence of the earthquake, the present invention has two spheres. The door can be locked.

  Further, the swing hook member has a swing protrusion formed on one of the lower surface side of the tip portion and the inner chamber of the casing, and the other is a swing support portion into which the swing protrusion is inserted. The swinging movement of the swinging hook member with respect to the housing is performed by the swinging protrusion and the swinging support, and the swinging hook member is substantially balanced with respect to the housing. The structure becomes a shape. Therefore, the swinging hook member swings smoothly, and the swinging hook member reacts sensitively even in a relatively small earthquake, and can prevent furniture doors or drawers from popping out due to the earthquake.

  In the invention of claim 2 and claim 3, the swing protrusion is formed on the lower surface side of the tip portion of the sensing portion, and the swing support portion is formed on the housing side. However, the configuration can be very simple, and the swing hook member can swing smoothly. According to the fourth and fifth aspects of the present invention, it is possible to make the swinging hook member difficult to come off in the casing and to stabilize the swinging operation of the swinging hook member.

  In the invention of claim 6, the partition portion is formed along the width direction of the housing and is configured to partition the inner chamber into a front small chamber and a rear small chamber along the front-rear direction. Each sphere accommodated in the rear small chamber 22 can operate the swing hook member by shortening the moving distance. And the movement distance for each sphere to operate the swing hook member is about half of the front and rear direction of the inner chamber, and the durability of the locked state by the sphere can be improved. Thereby, in the long-period vibration of an earthquake, even if the furniture door is locked once due to the occurrence of the earthquake, it is possible to prevent the inconvenience that the lock is released and the door or the drawer opens or jumps out.

  Further, since the casing is configured to partition the inner chamber into a front small chamber and a rear small chamber along the front-rear direction by the partition part, two spheres are arranged in the front small chamber and the rear small chamber, and each sphere is an earthquake The moving distance at the time of occurrence becomes small, and the followability to shaking becomes good. Therefore, the sensing part of the swinging hook member is always pushed up by one of the two spheres, and is maintained in a locked state with the locked member during the earthquake, This is extremely suitable for long-period shaking.

  In the invention of claim 7 and claim 8, the partition portion is formed along a diagonal direction of the inner chamber and partitions the inner chamber into two triangular left and right chambers along the width direction. By adopting the configuration, the movement operation of the sphere is further ensured. In the width direction of claim 9, the tip of the swing protrusion is a curved or arcuate arc-shaped tip edge that is symmetrical to the left and right, so that the swing hook member is not only in the front-rear direction. The oscillating hook member can react not only in the anteroposterior direction but also in the width direction (lateral direction) in a slight quake of a small earthquake.

  Hereinafter, the present invention will be described with reference to the drawings. First, the present invention is mainly composed of a casing A, a swinging hook member B, a cover material 6, two spheres 7, 7 and the like (see FIGS. 1 and 2). When actually used, a locked member 8 is further added. The housing A is composed of a bottom surface portion 11, a front side portion 12, a rear side portion 13, and left and right compatible upside portions 14 and 14, and these are formed into a substantially rectangular parallelepiped shape or a cubic shape such as a cube [FIG. FIG. 2 (A) and FIG. 3].

  A space inside the casing A is referred to as an inner chamber 2. That is, the inner chamber 2 is a space surrounded by the bottom surface portion 11, the front side portion 12, the rear side portion 13, and the left and right compatible upside portions 14 and 14. The upper part of the housing A, that is, the upper part of the inner chamber 2 is an opening 2a, which accommodates two spheres 7 and 7 and a swinging hook member B, which will be described later, and to which a cover material 6 is attached [ FIG. 1 (A), FIG. 2 (A), FIG.

  The casing A is set in the front-rear direction, the front side portion 12 is located on the front side, and the rear side portion 13 is located on the rear side. Further, a direction orthogonal to the front-rear direction of the casing A is defined as a width direction of the casing A. The casing A is installed so that the front side portion 12 faces the outside of the furniture main body 91 in a state where it is attached to the furniture main body 91 side of the furniture 9 such as a basket or a drawer, and the rear side portion 13 is the furniture main body 91. [See FIG. 8A].

  The front side portion 12 is formed with a cut-out portion 12a, and a hook lever portion 5 of a swinging hook member B, which will be described later, is inserted into the cut-out portion 12a and outward from the inner chamber 2 of the housing A on the front side. It is a site | part for protruding [refer FIG. 1, FIG. 2 (A), (C)]. The cut portion 12a is formed in a substantially square shape, and the hook lever portion 5 of the swing hook member B swings with little contact with the periphery of the cut portion 12a, and the swing operation is smoothly performed. .

  Mounting portions 16 and 16 are formed on the casing A (see FIGS. 2A, 2C, and 3). The mounting portions 16 and 16 together with a fastener such as a screw serve to attach the casing A to furniture. Both attachment portions 16 and 16 are formed integrally with the compatible upside portions 14 and 14. Specifically, the attachment portion 16 is formed in a substantially halved cylindrical shape extending in a substantially vertical (up and down) direction inside the inner chamber 2, and a portion formed to bulge toward the center side in the width direction of the inner chamber 2. It is. Through holes 16a and 16a are formed through which fixing members such as attachment parts 16 and 16 screws pass. Both attachment parts 16 and 16 are parts for mounting the casing A on the furniture main body 91 side (storage side) such as a chiffon and a shelf through a fixing tool such as a screw.

  The bottom surface portion 11 of the housing A is formed in a substantially rectangular mortar shape that is almost flat toward the center portion from the outer peripheral side, and the sphere 7 accommodated in the inner chamber 2 is a swinging hook member except for an earthquake. It is comprised so that it may stop at the position of the bottom face part 11 which does not operate B. Usually, such a position is often an intermediate position in the front-rear direction of the bottom surface portion 11.

  The outer peripheral portion of the bottom surface portion 11 is a periphery formed by corner portions formed with the front side portion 12, the rear side portion 13, and the compatible ascending side portions 14 and 14, respectively. As described above, the bottom surface portion 11 is formed in a substantially mortar-shaped flat mortar shape, and the spheres 7 and 7 are stationary at the lowest position of the mortar-shaped surface [ FIG. 1 (A), FIG. 4 (A), (D), FIG. 3 (A), FIG. 4 (D)]. In the bottom surface portion 11, a place where the spheres 7 and 7 are always stationary in a stable state is referred to as a stationary position (see FIGS. 1A and 4D).

  A partition portion 21 is formed in the inner chamber 2. The partition portion 21 divides the inner chamber 2 to form two small chambers 22 and 22 (see FIG. 1, FIG. 2 (A), FIG. 3, etc.). The partition portion 21 is formed in a substantially partition wall plate shape that rises from the bottom surface portion 11. The height of the partition portion 21 is about half of the height of the rising side portion 14 in the embodiments in the drawings. Further, the height of the rising side portion 14 is within a range that does not interfere with the swinging hook member B, and the sphere on which each of the small chambers 22 and 22 is arranged does not jump over and enter the other small chambers 22 and 22. If so, it is arbitrarily set, and its height is not limited.

  There are a plurality of embodiments in the structure in which the inner chamber 2 is partitioned into two small chambers 22 and 22 by the partition portion 21. First, in the first embodiment, the partition portion 21 is formed in the inner chamber 2 along the width direction of the housing A. That is, the partition part 21 is formed between the compatible ascending side parts 14 and 14 facing each other in the width direction of the casing A. The partition portion 21 is perpendicular to the rising side portion 14. The partition portion 21 forms two small chambers 22, 22 in the inner chamber 2 along the front-rear direction. The small chamber 22 on the front side is referred to as a front small chamber 22a, and the small chamber 22 on the rear side is referred to as a rear small chamber 22b (see FIGS. 1, 2A, 3A, 3B, etc.).

  The partition portion 21 is provided at an intermediate position in the front-rear direction of the inner chamber 2, and specifically, is provided slightly closer to the rear side than the center position in the front-rear direction of the inner chamber 2. As a result, the front small chamber 22a has a larger distance in the front-rear direction than the rear small chamber 22b (see FIGS. 1, 2A, 3A, 3B, etc.). Moreover, the partition part 21 is formed in the front-back direction intermediate position of the inner chamber 2, and the space | interval of the front-back direction of the front small chamber 22a and the rear small chamber 22b may be made equal. Further, the partition portion 21 may be positioned slightly closer to the front side than the intermediate position in the front-rear direction of the inner chamber 2.

  Two spheres 7 are arranged in each of the front small chamber 22a and the rear small chamber 22b. When no earthquake occurs and the vibration is not generated, the sphere 7 is in a state of being in contact with the partition portion 21 in the front-rear direction and the width direction center of the inner chamber 2 and stationary (see FIG. 4A). . The movement of the sphere 7 at the time of vibration due to the earthquake moves from here to the front and rear with the stationary position as the initial position [see FIGS. Therefore, the moving distance of the sphere 7 is extremely short compared to that in which the partition portion 21 does not exist.

  In the first embodiment of the present invention, as shown in FIGS. 1 to 5, the casing A partitions the inner chamber 2 into the front small chamber 22a and the rear small chamber 22b along the front-rear direction by the partition portion 21. Accordingly, two spheres 7 are arranged one by one in the front small chamber 22a and the rear small chamber 22b. Accordingly, the spheres 7 and 7 individually move to the front small chamber 22a and the rear small chamber 22b when an earthquake occurs, and thus the movement distances of the spheres 7 and 7 are small.

  Therefore, the spheres 7 and 7 have good followability to earthquake shaking. Therefore, the sensing part 4 of the swinging hook member B is always pushed up by one of the two spheres 7 and 7 and is locked to the locked member 8 during an earthquake. In this state, it is extremely suitable for long-period fluctuations (see FIGS. 4B and 4C).

  In 2nd Embodiment in this invention, the partition part 21 is formed along the front-back direction in the inner chamber 2 of the housing | casing A [refer FIG. 6 (A)]. That is, the partition portion 21 is formed between the front side portion 12 and the rear side portion 13 that face each other in the front-rear direction of the casing A. The partition portion 21 is perpendicular to the front side portion 12 and the rear side portion 13.

  The partition portion 21 forms two small chambers 22 and 22 that are located on the left and right sides of the inner chamber 2 along the width direction. In this embodiment, the left small chamber 22 is referred to as a left small chamber 22c, and the right small chamber 22 is referred to as a right small chamber 22d. The partition portion 21 is provided at an intermediate position in the width direction of the inner chamber 2. The left small chamber 22c and the right small chamber 22d have the same symmetrical shape.

  Two spheres 7 are arranged in each of the left small chamber 22c and the right small chamber 22d. When the earthquake is not occurring and the vibration is not occurring, the sphere 7 is stationary at a substantially intermediate position in the front-rear direction of the inner chamber 2. The movement of the sphere 7 during the vibration due to the earthquake moves along the front-rear direction of the inner chamber 2.

  In 3rd Embodiment, the partition part 21 is formed along the diagonal direction of the inner chamber 2 (refer FIG. 6 (B)). That is, the partition portion 21 is formed between the corner portion of the one rising side portion 14 and the front side portion 12 and the corner portion of the other rising side portion 14 and the rear side portion 13. The partition portion 21 forms two small chambers 22, 22 in the inner chamber 2. The small chamber 22 located on the left side in the width direction of the casing A is referred to as a left small chamber 22 c and is located on the right side in the width direction. The small chamber sensing unit 22 is referred to as a right small chamber 22d. The left small chamber 22c and the right small chamber 22d have the same shape that is substantially point-symmetric with respect to the common center point in the front-rear direction and the width direction of the inner chamber 2.

  Two spheres are arranged in each of the left small chamber 22c and the right small chamber 22d. The sphere is stationary at a substantially central position in the front-rear direction of the inner chamber 2 when no earthquake is occurring. The movement of the sphere at the time of vibration due to the earthquake moves along the front-rear direction of the inner chamber 2.

  A rear flat bulged portion 11a is formed on the rear side of the bottom surface portion 11 (see FIGS. 3A and 3B). The rear flat bulged portion 11a is formed so as to protrude gradually toward the stationary position at the substantially central portion of the bottom surface portion 11 so that the width gradually decreases in the width direction. The rear flat bulged portion 11 a is a flat bulged portion formed in a substantially triangular shape, and the oblique side portion of the outer periphery thereof is formed as an inclined surface so as to spread toward the bottom surface portion 11.

  Next, the two spheres 7 and 7 have the same diameter, are formed of metal, and have an appropriate weight. The weight affects the initial motion of the spheres 7 and 7. Therefore, the weights of the spheres 7 and 7 are determined depending on the magnitude of the earthquake. The spheres 7 and 7 preferably have a high true sphere accuracy in order to perform an accurate operation. Further, the diameters of the spheres 7 and 7 are approximately half of the dimension in the left-right direction (width direction) of the casing A, and the base 7 of the casing A rolls to move an appropriate distance. It is something that can be done.

  Next, the swing hook member B is composed of a sensing portion 4 and a hook lever portion 5. The sensing part 4 has a receiving surface 41 that is recessed flatly from the outer peripheral side toward a substantially central portion on the lower surface side (FIGS. 1A, 1B, 2A and 2A). See FIG. 4 etc.]. Further, a hook lever portion 5 that protrudes outward from the sensing portion 4 is formed.

  The hook lever portion 5 includes a hook piece 51 and a lever portion 52, and the hook piece 51 is formed at the tip, that is, the end portion of the lever portion 52. The hook piece 51 has a hook shape and is easily hooked to a loop-shaped portion 81 of the locked member 8 to be described later. The lever portion 52 is formed so as to incline slightly upward from the base portion with the sensing portion 4 outward and extend outward from the upper end portion in a substantially horizontal shape. As described above, the sensing unit 4 and the hook lever unit 5 are integrally formed rigid bodies.

  The swing hook member B is attached to the housing A so as to be swingable. Further, the hook lever portion 5 is arranged so as to protrude outward from the cutout portion 12a formed in the front side portion 12 of the case A. And the hook lever part 5 can rock | fluctuate the said cutting part 12a location to an up-down direction. That is, the sensing unit 4 is disposed inside the housing A, and the hook lever portion 5 is located outside the housing A.

  The receiving surface 41 of the sensing unit 4 is arranged so as to be able to come into contact with the spheres 7 and 7 arranged in both the small chambers 22 and 22 of the housing A (see FIG. 4A). In a state where the two spheres 7 and 7 are located at the stationary position of the bottom surface portion 11 and the receiving surface 41 of the sensing portion 4 and the two spheres 7 and 7 are stationary without vibration, the sensing portion 4 and the hook lever portion 5 Is almost horizontal. This horizontal state is a state in which the swinging hook member B is not locked with the locked member 8 described later, that is, a locked state (see FIG. 4A).

  The weight of the sensing unit 4 is set to be greater than the weight of the hook lever unit 5. When the swing hook member B is mounted on the housing A, the swing hook member B can swing by a swing protrusion 31 and a swing support portion 32 described later. At this time, in the natural state, the sensing unit 4 is always urged downward by its own weight, and the hook lever unit 5 is urged upward in the opposite direction. And even if the hook lever part 5 is once lowered downward due to the shaking or impact at the time of the earthquake, the hook lever part 5 returns to the original position due to the weight of the sensing part 4 as the earthquake ends.

  As a means for making the weight of the sensing portion 4 larger than the weight of the hook lever portion 5, for example, the sensing portion 4 is made of a thick material, or a large number of small through holes are formed in the hook lever portion 5. May be reduced. As will be described later, the sensing unit 4 operates by the movement of the spheres 7 and 7 in the housing A by rolling, and the weight of the sensing unit 4 is determined in consideration of this point. . Next, the cover member 6 serves to close the opening 2a of the inner chamber 2 of the casing A, and prevents the two spheres 7 and 7 and the swinging hook member B from jumping out of the casing A. It plays a role (see FIG. 1A).

  A configuration in which the swing hook member B is swingable will be described. A swing projection 31 is formed in one of the inner chamber 2 of the housing A and the swing hook member B, and a swing support 32 is inserted into the other in the other. There are a plurality of embodiments of the swing mechanism including the swing protrusion 31 and the swing support portion 32.

  First, as a first embodiment of the swing mechanism, the swing protrusion 31 is formed on the swing hook member B side, and the swing support 32 is formed on the housing A. The swing protrusion 31 is formed at the front end side portion of the swing hook member B and on the lower side [FIG. 1 (A), FIG. 2 (A), (B), FIG. A) etc.]. The swing protrusion 31 has a substantially roof shape in which the cross section orthogonal to the longitudinal direction is the same cross-section substantially triangular or substantially V-shaped at any position along the width direction. [Refer to FIG. 1 (A), FIG. 2 (A), (B), FIG. 3 (A)).

  Further, the swing support portion 32 is formed on the housing A side, and is formed on the front side of the housing A and below the inner chamber 2 side of the front side portion 12 [FIG. ), (C), FIG. 2 (A), FIG. 3 (A), (B), etc.] The swing support portion 32 is formed at a corner portion of the bottom surface portion 11 and the front side portion 12, and a substantially rectangular parallelepiped support base 32b is formed at the corner portion, and the substantially rectangular parallelepiped support base 32b. A support groove 32a having a substantially V-shaped cross section is formed (see FIGS. 1A, 1C, 2A, 3A, and 3B).

  That is, the swing support portion 32 is formed by forming a support groove 32a in a support base 32b having a substantially rectangular parallelepiped shape. The support groove 32a is a groove-like portion formed linearly along the width direction of the casing A (see FIGS. 1C and 3B). The swing support portion 32 may be formed integrally with the bottom surface portion 11 and the front side portion 12 of the housing A, or the swing support portion 32 may be formed as a separate member with respect to the housing A.

  The tip of the swing projection 31 enters the support groove 32a of the swing support portion 32, and the swing projection 31 can swing within the support groove 32a. The angle of the inner angle of the support groove 32a is larger than the tip angle of the swinging protrusion 31 (see FIGS. 1A, 3A, 4). That is, the swinging hook member B and the swinging support part 32 of the casing A can swing the swinging hook member B with a substantially balance-like structure. [Refer to Drawing 4 (A) thru / or (C)].

  In a second embodiment of the swing mechanism, the swing protrusion 31 is formed on the housing A side, and the swing support portion 32 is formed on the swing hook member B side (see FIG. 5A). ]. In this embodiment, the swinging protrusion 31 is formed on the housing A, and has a triangular roof shape on the front side of the housing A from the lower side on the inner chamber 2 side of the front side portion 12 upward. Formed.

  The swing support portion 32 is formed below the front end side of the sensing portion 4 of the swing hook member B.

The attachment fixing portion 82 is a portion that is fixed to the furniture door 92 via a fixing tool such as a screw (see FIG. 8B). The loop-shaped portion 81 is a portion where the hook piece 51 of the swinging hook member B can be locked (see FIGS. 4B and 4C).

  With the above configuration, when an earthquake occurs, the spheres 7 and 7 roll from the stationary position in the casing A and move to the outer peripheral portion of the bottom surface portion 1. By movement of both spheres 7, 7, the spheres 7, 7 move while contacting the shallowest position of the receiving surface 41 of the swing hook member B. Then, it acts to push up the receiving surface 41 of the spheres 7 and 7 from below, so that the sensing part 4 is pushed up and the sensing part 4 moves upward, so that the hook lever part 5 is lowered, The hook piece 51 is locked to the locked member 8.

  In order to mount the earthquake response tool of the present invention on the furniture 9 such as a bag or a drawer, the frame A is mounted at the upper end portion of the opening of the furniture body 91 (see FIG. 8A). Further, the locked member 8 is fixed to the door 92. The positional relationship between the earthquake response tool and the locked member 8 is that the loop-shaped portion 81 is the hook of the swinging hook member B of the earthquake response tool when the earthquake response tool is in a natural state (a state where no earthquake has occurred). It is located slightly below the piece 51 (see FIG. 4A). Then, when the earthquake occurs, the swinging hook member B swings, the hook lever portion 5 is lowered, and the hook piece 51 is locked to the loop-shaped portion 81 of the locked member 8, whereby the door 92 is closed. It is locked in a state [see FIGS. 4B and 4C].

  When the earthquake occurs, the hook lever portion 5 of the swing hook member B is lowered, the hook piece 51 is locked to the locked member 8, and the door 92 is locked so as not to open. When the earthquake is finished, the spheres 7 and 7 are moved to the lower position of the bottom surface portion 1 and the locked state is released [see FIG. 4A].

  As described above, in the earthquake response tool of the present invention, when the earthquake occurs, the spheres 7 and 7 roll and move from the stationary position of the bottom surface portion 1 and push the sensing portion 4 of the swing hook member B upward. Thus, the door 92 of the furniture body 91 is locked at the closed position (see FIGS. 4B and 4C). Further, when the earthquake ends with the sensing portion 4 of the swinging hook member B being pushed up and the door 92 is locked, the spherical passage formed between the flat bulging portions adjacent to the spherical bodies 7 and 7 is moved to a stationary position. , The sensing portion 4 is lowered, the hook lever portion 5 is raised, the hook piece 51 is detached from the locked member 8, and the door 92 can be unlocked (FIG. 4A). reference〕.
