Stop.

  On the other hand, in the housing recess 22 of the case body 21, a latch body 51, which is a locking body serving as a locking means having an elongated rectangular shape in side view, is rotatably attached and stored. The latch body 51 is located at a position perpendicular to the direction in which the seismic sensing body 41 swings relative to the seismic sensing body 41 that is swingably accommodated in the housing recess 22 of the case body 21, that is, the case body 21. Are juxtaposed at positions along the thickness direction.

  The latch body 51 has a longitudinal dimension slightly smaller than the longitudinal dimension of the housing recess 22 of the case body 21 and a width dimension substantially equal to the width dimension of the housing recess 22. Then, an engaging surface 52 that is an arcuate arc surface as an engaging surface corresponding to the arc surface 23 of the housing recess 22 of the case body 21 is formed at the distal end that is one end in the longitudinal direction of the latch body 51. Has been.

  Further, a shaft insertion hole 53 that penetrates in the width direction that is the vertical direction of the latch body 51 is provided in the rear end portion that is the other end in the longitudinal direction of the latch body 51. The shaft insertion hole 53 allows the front end side of the latch body 51 to turn in the horizontal direction, that is, in the thickness direction of the latch body 51. At this time, the latch body 51 is configured such that the rotation axis direction of the latch body 51 and the swinging direction of the seismic sensing body 41 are orthogonal to each other.

  Therefore, the shaft insertion hole 53 has an elongated rod-like pin body 54 serving as a rotation shaft in the circumferential direction with the upper end and the lower end of the shaft insertion hole 53 communicating with the shaft stop hole 28 of the case body 21. It is slidably inserted in. The pin body 54 is slidably inserted into the shaft insertion hole 53 of the latch body 51, and the upper end and the lower end of the pin body 54 are inserted into the shaft stop hole 28 of the case body 21 and fixed. ing. Therefore, the pin body 54 can rotate the latch body 51 so that the engaging surface 52 on the distal end side of the latch body 51 protrudes from the inside of the housing recess 22 of the case body 21 in the horizontal direction. The receiving recess 22 is pivotally supported and fixed. That is, the latch body 51 is configured to protrude in the width direction of the drawer body 3, which is a direction orthogonal to the moving direction of the drawer body 3.

  Further, an engaged protrusion 55 having a shape corresponding to the engagement protrusion 31 of the case body 21 protrudes from the lower surface in the vertical direction that is the width direction of the latch body 51. The engaged protrusion 55 is concentrically provided at the opening edge of the shaft insertion hole 53 that penetrates to the lower surface of the latch body 51.

  The engaged protrusion 55 includes a flat part 57 that comes into contact with the flat part 32 of the engaging protrusion 31 of the case body 21. Near the rear end of the flat portion 57, it contacts the inclined surface portion 35 of the engaging projection 31 of the case body 21, and the latch body 51 slides into the housing recess 22 of the case body 21 by its own weight. A sliding contact surface portion 58 is formed as a sliding contact portion.

  In other words, the sliding contact surface portion 58 contacts the inclined surface portion 35 of the case body 21 by the action of the own weight of the latch body 51 and accommodates the latch body 51 in the accommodating recess 22 of the case body 21. At this time, in the sliding contact surface portion 58 and the inclined surface portion 35, the force for accommodating the latch body 51 in the housing recess 22 of the case body 21 is smaller than the force for the seismic sensing body 41 to press the latch body 51 during the earthquake. As described above, the inclination angles of the sliding contact surface portion 58 and the inclined surface portion 35 are set.

  Here, the engaged protrusion 55 constituted by the flat portion 57 and the slidable contact surface portion 58 is an urging mechanism as an urging means for urging the latch body 51 toward the inside of the housing recess 22 of the case body 21. Part of 56. Then, the urging mechanism 56 faces the direction in which the engaging surface 52 of the latch body 51 is accommodated in the accommodating recess 22 of the case body 21, where the engaging surface 52 of the latch body 51 is opposite to the protruding direction. The latch body 51 is configured to be biased.

  Further, a coil spring 59, which is a pressing means as an elastic means, is attached between the upper surface of the latch body 51 and the lower surface of the housing recess 22 of the case body 21. The coil spring 59 is a coil spring, and is inserted between the latch body 51 and the housing recess 22 of the case body 21 with the pin body 54 inserted therethrough, and presses the latch body 51 downward. Then energize. That is, the coil spring 59 presses the sliding contact surface portion 58 of the latch body 51 against the inclined surface portion 35 of the case body 21. Therefore, the coil spring 59 also constitutes a part of the biasing mechanism 56.

  That is, the coil spring 59 is generated by the weight of the latch body 51 between the sliding contact surface portion 58 of the latch body 51 and the inclined surface portion 35 of the case body 21, and into the housing recess 22 of the case body 21 of the latch body 51. The urging of the latch body 51 is made to act more reliably. At this time, the coil spring 59 has a force that allows the latch body 51 to be housed in the housing recess 22 of the case body 21 by the elastic force of the coil spring 59. The elastic force of the coil spring 59 is set so as to be smaller.

  Further, on the inner side surface, which is one side surface in the thickness direction of the latch body 51, a swing receiving portion 61 is provided as a concave arc-shaped contact recess that penetrates the latch body 51 in the vertical direction. . The swing receiving portion 61 has a longitudinal dimension larger than the longitudinal dimension of the upper end portion of the seismic sensing body 41. Further, the swing receiving portion 61 causes the distal end side of the latch body 51 to protrude from the housing recess 22 of the case body 21 by swinging along the longitudinal direction of the seismic sensing body 41. That is, on both side edges along the width direction of the swing receiving portion 61, arcuate inclined surfaces 62 that are inclined corresponding to the action surface 43 of the seismic sensing body 41 are provided.

  These inclined surfaces 62 are inclined with respect to the longitudinal direction of the latch body 51, which is the moving direction of the drawer body 3. That is, when the seismic body 41 swings along the longitudinal direction, these inclined surfaces 62 come into contact with any one working surface 43 of the seismic body 41, so that the working surface of the seismic body 41 Due to the contact of 43, the latching surface 52 of the latch body 51 protrudes outside the housing recess 22 of the case body 21. Further, these inclined surfaces 62 are inclined with respect to the moving direction of the drawer body 3 and are perpendicular to the bottom plate portion 4 of the furniture body 2 to which the drawer body 3 is attached.

  On the other hand, on at least one outer surface of the pair of side plate portions 5 of the drawer body 3, a latch receiving tool 71 as a moving member as a locked body is attached. The latch receiver 71 is a locking body receiver to which the earthquake-resistant latch 1 is engaged during the earthquake. Further, the latch receiver 71 is attached to the side plate portion 5 on the side where the seismic latch 1 is attached. That is, the latch receiver 71 may be attached only to one side plate portion 5 of the drawer body 3 or to each of the pair of side plate portions 5 of the drawer body 3.

  The latch receiver 71 includes an attachment member 72 attached to the outer surface of the side plate portion 5 of the drawer body 3. A locked member 73 is attached to the attachment member 72 so as to be rotatable with respect to the attachment member 72. The locked member 73 is attached to the back surface of the front plate 14 of the drawer 3 while the locked member 73 is rotated. In order to prevent this, the mounting member 72 is rotatably attached.

  Further, the locked member 73 is formed in an elongated and substantially rectangular flat plate shape, and is attached to the drawer body 3 in a state where the longitudinal direction is along the drawer direction which is the moving direction of the drawer body 3. . Further, the engaged member 73 has a base end edge, which is one end edge in the longitudinal direction, rotatably attached to the attachment member 72 via a pin body 74. That is, the locked member 73 is attached to be rotatable in a direction along the horizontal direction.

  Further, the leading end edge which is the other end in the longitudinal direction of the locked member 73 is an arc surface 75 having an arc shape in a side view. The circular arc surface 75 is formed across the width direction of the locked member 73. A locked recess 76 penetrating in the thickness direction of the locked member 73 is formed on the base end side of the distal end edge of the locked member 73. The engaged recess 76 is opened in a substantially rectangular shape, and the inner surface on the distal end side of the locked recess 76 has an arc shape as a locked portion parallel to the distal end edge of the locked recess 76. The locking edge portion 77 is formed.

  The locking edge 77 is formed in a shape that allows the engagement surface 52 of the latch body 51 to be engaged. That is, the locking edge 77 has a slightly larger width than the engaging surface 52 of the latch body 51 and is formed in an arc shape having a larger curvature than the engaging surface 52. Therefore, the engagement surface 52 of the latch body 51 that is rotated and protruded by the pressing of the seismic body 41 due to the change in the posture of the seismic body 41 of the seismic latch 1 is engaged with the locking edge 77. It is configured.

  Next, the operation of the first embodiment will be described.

  4 and 5, when the shaft body 44 of the seismic sensing body 41 of the earthquake-resistant latch 1 is inserted into the shaft support hole 27 of the case body 21 as shown in FIGS. The seismic body 41 is in a normal posture on the pedestal 26.

  Therefore, the force applied by the weight of the latch body 51 between the inclined surface portion 35 of the case body 21 and the sliding contact surface portion 58 of the latch body 51 and the elastic force of the coil spring 59 enter the housing recess 22 of the case body 21. Due to the biasing of the latch body 51, the latch body 51 is housed in the housing recess 22 in a state where the engaging surface 52 of the latch body 51 does not protrude outward from the housing recess 22 of the case body 21.

  For this reason, when the drawer body 3 is pulled out from the furniture body 2, the engagement surface 52 of the latch body 51 of the earthquake-resistant latch 1 does not engage with the latching edge portion 77 of the latch receiver 71. The body 3 can be pulled out.

  Next, when an earthquake occurs in the state where the drawer body 3 is accommodated in the furniture body 2, as shown in FIGS. 6 and 7, the seismic body 41 of the earthquake-resistant latch 1 is moved in the moving direction of the drawer body 3, as shown in FIGS. The seismic sensing body 41 changes its posture from a normal posture to a state inclined at a predetermined inclination angle.

  At this time, the action surface 43 of the seismic body 41 abuts on the inclined surface 62 of the latch body 51 due to a change in the posture of the seismic body 41 along the direction of movement of the drawer body 3 and presses the inclined surface 62. To do.

  As a result, when the inclined surface 62 of the latch body 51 is pressed by the action surface 43 of the seismic body 41, the force that causes the seismic body 41 to fall along the moving direction of the drawer body 3 causes the inclination of the latch body 51. The force is converted into a force that causes the engaging surface 52 of the latch body 51 to project at the surface 62, which is a direction orthogonal to the moving direction of the drawer body 3.

  That is, when the inclined surface 62 of the latch body 51 is pressed by the action surface 43 of the seismic sensing body 41, the latch body 51 acts by its own weight between the inclined surface portion 35 of the case body 21 and the sliding contact surface portion 58 of the latch body 51. The engagement surface 52 of the latch body 51 is formed on the case body 21 against the force that causes the latch body 51 to be accommodated in the accommodation recess 22 of the case body 21 due to the force and the elastic force of the coil spring 59. Projecting from the inside of the housing recess 22 to the outside.

  Therefore, the engaging surface 52 of the latch body 51 protruding from the housing recess 22 of the case body 21 is engaged and locked with the locking edge 77 of the latch receiver 71.

  As a result, the drawer body 3 cannot be pulled out from the interior of the furniture body 2 by the engagement of the latching body 51 with the engaging edge 52 to the locking edge 77, so that the drawer body 3 from the furniture body 2 due to vibration can be prevented. Jumping out is prevented.

  As described above, according to the first embodiment, the seismic body 41 of the earthquake-resistant latch 1 swings along the moving direction of the drawer body 3 during a vibration. When the seismic body 41 swings, the action surface 43 of the seismic body 41 abuts on the inclined surface 62 of the latch body 51 that is inclined. As a result, the force on which the seismic sensing body 41 swings and falls is caused by the inclined surface 62 of the latch body 51 in the direction orthogonal to the moving direction of the drawer body 3, and the engagement surface 52 of the latch body 51. Is converted into a force to cause

  Therefore, the engaging surface 52 of the latch body 51 protrudes from the housing recess 22 of the case body 21 by the swinging of the seismic body 41. For this reason, regardless of the mounting direction of the seismic latch 1 and the latch receiver 71, the engagement surface 52 of the latch body 51 is brought into contact with the locking edge 77 of the latch receiver 71 due to the posture change of the seismic sensing body 41 during vibration. The drawer body 3 to which the latch receiver 71 is attached is fixed in the furniture body 2 by being locked.

  As a result, the drawer body 3 cannot be pulled out from the furniture body 2 during vibration, and the drawer body 3 can be prevented from jumping out of the furniture body 2.

  Further, with respect to the seismic body 41 that is swingably accommodated in the housing recess 22 of the case body 21, a latch body 51 is provided in parallel at a position orthogonal to the direction in which the seismic body 41 swings. As a result, the latch body 51 and the seismic sensing body 41 can be accommodated in the housing recess 22 of the case body 21 more efficiently, and the seismic latch 1 can be further downsized.

  At this time, the seismic sensing body 41 of the seismic latch 1 was formed into a flat plate shape that is a triangular shape in a side view with the upper side expanded from below. Therefore, the inclination angle and the radius of curvature of the action surface 43 of the seismic sensing body 41, which is a portion that contacts the inclined surface 62 of the latch body 51, can be freely set. In addition, when the swing of the seismic body 41 exceeds the set swing angle, a substantially constant force is generated on the seismic body 41, so that stable seismic sensitivity can be obtained. .

  In addition, inclined surfaces 62 are provided on both side edges along the width direction of the swing receiving portion 61 of the latch body 51. As a result, even if the seismic body 41 falls in any direction along the direction of movement of the drawer body 3 and the posture changes, the action surface 43 of the seismic body 41 is in any one of the latch bodies 51. It contacts the inclined surface 62.

  Therefore, the engagement surface 52 of the latch body 51 protrudes from the housing recess 22 of the case body 21 by pressing the action surface 43 of the seismic sensing body 41 against the inclined surface 62 of the latch body 51. For this reason, since the engagement surface 52 of the latch body 51 can be engaged with the locking edge 77 of the latch receiver 71, the drawer body 3 can be prevented from being pulled out from the furniture body 2.

  Further, an inclined surface portion 35 is provided at the opening edge of the shaft stop hole 28 on the lower surface side in the housing recess 22 of the case body 21, and a sliding contact surface portion 58 is provided at the opening edge of the shaft insertion hole 53 on the lower surface of the latch body 51. . Then, the case body 21 is attached to the side plate portion 5 of the furniture body 2 so that the seismic sensing body 41 is placed on the mounting base portion 26 of the case body 21, and the sliding contact surface portion 58 of the latch body 51 is attached to the case. The latch body 51 is urged into the housing recess 22 of the case body 21 by being brought into contact with the inclined surface portion 35 of the body 21 and utilizing its own weight.

  As a result, when the seismic motion of the seismic body 41 returns, the sliding contact surface portion 58 of the latch body 51 slides against the inclined surface portion 35 of the case body 21 due to the weight of the latch body 51, and this latch body 51 is housed in the housing recess 22 of the case body 21. Therefore, when the seismic motion of the seismic body 41 returns without attaching a biasing means such as a coil spring 59 between the case body 21 and the latch body 51, the engagement surface 52 of the latch body 51 protrudes. Is released, and the engagement surface 52 of the latch body 51 is disengaged from the latch edge 71 of the latch receiver 71.

  For this reason, the drawer body 3 in the furniture body 2 is released from being stopped, and the drawer body 3 can be pulled out from the furniture body 2. Therefore, the seismic operation of the seismic latch 1 can be reliably canceled when the vibration is stopped by a simple configuration in which the inclined surface portion 35 is provided on the case body 21 of the earthquake resistant latch 1 and the sliding contact surface portion 58 is provided on the latch body 51. That is, a mechanism for urging the latch body 51 into the housing recess 22 of the case body 21 can be easily built into the case body 21 and the latch body 51, and the latch body 51 is placed in the case body 21. The structure of the urging mechanism can be simplified.

  Further, the coil spring 59 is inserted through the pin body 54 inserted between the case body 21 and the latch body 51, and the latch body 51 is attached to the housing recess 22 of the case body 21 by the elastic force of the coil spring 59. It was set as the structure accommodated. As a result, the latch body 51 is reliably accommodated in the accommodation recess 22 of the case body 21 when the vibration is stopped by the elastic force of the coil spring 59. Therefore, since the return operation, which is the release of the seismic operation of the seismic latch 1 when the vibration is stopped, can be assisted by the elastic force of the coil spring 59, the release of the seismic operation of the seismic latch 1 when the vibration is stopped can be performed more reliably.

  In the first embodiment, the latch body 51 is urged toward the inside of the housing recess 22 of the case body 21 by the elastic force of the coil spring 59. The latch body 51 can be directly urged into the case body 21 by urging means such as a spring. The urging means can be constituted by a flexible elastic means such as a resin member or a metal plate integrally formed with the latch body 51 or the case body 21.

  Further, the case body 21 is attached to the inner side surface of each side plate portion 5 of the furniture body 2, and the latch receiver 71 is attached to the outer side surface of each side plate 12 of the drawer body 3. The case body 21 may be provided with the case body 21 so as to function as a fixing member, or the side plate 12 itself of the drawer body 3 may be functioned as the latch receiver 71 to serve as a moving member.

  Further, as in the second embodiment shown in FIG. 8, a spherical large diameter portion 81 may be provided at the tip of the shaft body 44 of the seismic sensing body 41. In this case, the large-diameter portion 81 is formed in a spherical shape having a larger diameter than the diameter of the shaft body 44 of the seismic sensing body 41. Further, the large-diameter portion 81 is inserted into the shaft support hole 28 of the case body 21 and is fitted and fixed in the shaft support hole 28 so as to be swingable and rotatable.

  As a result, even if the thickness direction of the earthquake-resistant latch 1 is set along the vertical direction or the upper and lower sides of the earthquake-resistant latch 1 are turned upside down, the seismic body 41 of the earthquake-resistant latch 1 changes its posture during the earthquake and latches. The engaging surface 52 of the body 51 is projected outward from the housing recess 22 of the case body 21.

  Further, at this time, the sliding force contact surface portion 58 of the latch body 51 is pressed against the inclined surface portion 35 of the case body 21 by the elastic force of the coil spring 59, and the latch body 51 against the inclined surface portion 35 of the case body 21 is pressed. The sliding contact surface portion 58 is forced to act. As a result, regardless of the mounting direction of the seismic latch 1, when the seismic motion of the seismic body 41 of the seismic latch 1 is restored, the latch body 51 is forcibly forced by the elastic force of the coil spring 59. Is housed in the housing recess 22.

  Therefore, regardless of the mounting direction of the seismic latch 1, the engaging surface 52 of the latch body 51 can be protruded and engaged with the latching edge 77 of the latch receiver 71 during the earthquake, and the latch body 51 can be engaged when the vibration is stopped. Engagement of the latch receiving member 71 with the engaging edge 52 by the engaging surface 52 is reliably released by the elastic force of the coil spring 59.

  As a result, the mounting direction of the seismic latch 1 can be freely changed, so that the installation location of the seismic latch 1 is not limited. Therefore, the left and right side and the top and bottom sides of the seismic latch 1 can be eliminated, and the usability of the seismic latch 1 can be improved.

  Further, as in the third embodiment shown in FIG. 9, a spring body 82 having both ends projecting outward from the outer peripheral surface is attached to the pin body 54 attached to the shaft support hole 27 of the case body 21. Thus, the latch body 51 may be urged into the housing recess 22 of the case body 21 by the elastic force of the spring body 82.

  In this case, the spring body 82 includes a spring body 83 formed by spirally winding a steel wire. The spring body 83 is inserted between the lower surface of the latch body 51 and the lower surface of the housing recess 22 of the case body 21, and the shaft insertion hole 53 of the latch body 51 and the shaft stop hole of the case body 21 A pin body 54 inserted through and attached to 28 is inserted.

  And at both ends of the spring body 83, there are a pair of leg portions 84 in which both ends of the steel wire spirally wound around the spring body 83 are projected in the tangential direction of the spring body 83. Is provided. The pair of leg portions 84 protrudes in a direction perpendicular to the axial direction of the spring body 83.

  Here, the one leg portion 84 is locked to a locking projection 85 as a locking portion protruding on the side surface located on the other side in the thickness direction in the housing recess 22 of the case body 21. Yes. The locking projection 85 is provided at a position near the front end in the housing recess 22 of the case body 21, and one leg portion of the spring body 82 is provided on one side surface that is located on the front end side of the locking projection 85. 84 is locked.

  Further, the other leg portion 84 of the spring body 82 is locked to a locking piece portion 86 as a locking portion protruding from the base end edge of the latch body 51. The locking piece 86 is provided at the edge on the base end side in the longitudinal direction of the latch body 51, and the other leg 84 of the spring body 82 is locked to the distal end side of the locking piece 86. ing.

  Therefore, the spring body 82 is moved toward the side where the latch body 51 is accommodated in the housing recess 22 of the case body 21 by the elastic force acting between the pair of legs 84 of the spring body 82. Energize 51. At this time, in the spring body 82, the force that causes the latch body 51 to be housed in the housing recess 22 of the case body 21 by the elastic force of the coil spring body 82 causes the seismic body 41 to press the latch body 51 during the earthquake. The elastic force of the spring body 82 is set to be smaller than the force.

  As a result, when the posture change of the seismic body 41 of the earthquake-resistant latch 1 is restored, the latch body 51 is forcibly accommodated in the accommodating recess 22 of the case body 21 by the elastic force of the spring body 82, and this latch body. Since the engagement of the latch receiver 71 by the engagement surface 52 of 51 with the locking edge 77 is released, the same effect as the first embodiment can be obtained.

  Further, as in the fourth embodiment shown in FIG. 10, the seismic latch 1 can be attached in a state where the longitudinal direction of the seismic latch 1 is aligned vertically. In this case, the case body 21 of the earthquake-resistant latch 1 is attached in a state where the longitudinal direction is along the vertical direction which is the vertical direction. A mounting recess 24 is provided at the upper end of the housing recess 22 of the case body 21, and a mounting base 26 is provided at the center of the lower end surface of the housing recess 22.

A pin body 54 is inserted and attached to the shaft stop hole 28, and an upper end portion of the latch body 51 is rotatably attached to the pin body 54.

  Here, the latch body 51 is housed in the housing recess 22 of the case body 21 in a state where the longitudinal direction is along the vertical direction. In addition, a shaft insertion hole 53 penetrating along the width direction of the latch body 51 is provided at the upper end portion of the latch body 51.

  Further, each of the outer surfaces located on both sides in the width direction of the latch body 51 is provided with a step-like widening step portion 88 that widens the lower end side wider than the upper end side of the latch body 51. Yes. The widening step 88 is formed in a shape corresponding to each widening step 87 of the housing recess 22 of the case body 21. At this time, both side surfaces in the width direction of the latch body 51 below the widened step portion 88 become the engaging surfaces 52.

  For this reason, since the seismic latch 1 can be attached between the furniture main body 2 and the drawer body 3 only by attaching the slide rail 91, compared with the case where the seismic latch 1 is separately attached to the furniture body 2 and the drawer body 3, this seismic resistance. The attachment work of the latch 1 can be simplified.

  At this time, a spring body (not shown), which is a pressing means as an elastic means, is attached to the pin body 54 that rotatably locks the latch body 51 of the earthquake-resistant latch 1 to the case body 21, and the elastic force that the spring body has. The latch body 51 may be biased so that the front end side of the latch body 51 rotates downward.

  As a result, the elastic force of the spring body assists in housing the case body 21 in the housing recess 22 due to the weight of the latch body 51 when the seismic latch 1 is not struck. Therefore, the seismic latch 1 can be turned upside down and attached to the slide rail 91 so that the latch body 51 of the seismic latch 1 protrudes downward during the earthquake.

These holding recesses 115 are juxtaposed with the travel recesses 114 and are opened to communicate with the side surfaces of the travel recesses 114. The seismic latch 1 accommodated and held in the holding recesses 115 causes the engaging surface 52 of the latch body 51 to move by swinging the seismic body 41 along the moving direction of the sliding door 113 of the seismic latch 1. Project into the running recess 114.

  On the other hand, a pair of pivot shafts 116 that are latch receivers as locking body receivers protrude from the upper end surface of each sliding door body 113. The pivot shafts 116 are shaft bodies serving as locked portions that are locked to the engaging surfaces 52 of the latch bodies 51 that protrude when the earthquake-resistant latch 1 is sensed. Further, these pivot shafts 116 are attached at positions spaced from the central portion of the upper end surface of the sliding door body 113 at equal intervals in the longitudinal direction of the upper end surface.

  These pivot shafts 116 are fitted in the running recess 114 of the upper guide rail 111 so as to be able to run and slide. Accordingly, the pivot shafts 116 come into contact with the engagement surface 52 of the latch body 51 by the protrusion of the engagement surface 52 of the latch body 51 into the traveling recess 114 by the seismic operation of the earthquake-resistant latch 1, and the sliding door body. The movement of 113 along the upper guide rail 111 is configured to be fixed.

  Further, a guide roller 117 that is rotatable along the moving direction of the sliding door body 113 is attached to the lower end portion of each sliding door body 113. The guide roller 117 is attached to a position spaced from the central portion of the lower end surface of the sliding door body 113 at equal intervals in the longitudinal direction of the lower end surface. The guide rollers 117 are fitted in a travel groove 118 provided on the upper side surface of the lower guide rail 112 so as to travel. These running groove portions 118 are formed in a concave groove shape along the longitudinal direction of the lower guide rail 112. Further, the travel groove portions 118 are provided at positions facing the travel recess portions 114 of the upper guide rail 111.

  As a result, when a shaking vibration, which is the moving direction of each sliding door body 113, occurs, the seismic sensing body 41 of the earthquake-resistant latch 1 moves along the moving direction of the sliding door body 113. The latch body 51 is pressed, the engagement surface 52 of the latch body 51 is protruded into the traveling recess 114 of the upper guide rail 111, and the engagement surface 52 of the latch body 51 is moved to the pivot shaft 116 of each sliding door body 113. It was set as the structure made to contact | abut and latch.

  For this reason, since the movement of each sliding door body 113 is fixed by the seismic operation of the earthquake-resistant latch 1, even the sliding door body 113 attached between the upper guide rail 111 and the lower guide rail 112 is the first The same effects as the embodiment can be achieved.

  Although the seismic latch 1 is attached to the upper guide rail 111 in the sixth embodiment, the seismic latch 1 is attached to the lower guide rail 112 by turning the seismic latch 1 upside down. The seismic latch 1 can also be configured to fix the movement of the sliding door body 113 during the earthquake.

  Furthermore, in each of the above-described embodiments, the earthquake-resistant latch that prevents the drawer body 3 housed in the furniture body 2 and the sliding door body 113 attached between the upper guide rail 111 and the lower guide rail 112 from moving during vibration. 1 has been described, but the earthquake-resistant latch 1 is attached between a hinged door (not shown) that is pivotally supported at one end and a door (not shown) in which the hinged door is opened and closed. It is also possible to adopt a configuration in which the opening is prevented by the seismic operation of the earthquake-resistant latch 1.

  In each of the above embodiments, the weight main body 42 of the seismic sensing body 41 has a substantially triangular flat plate shape in side view, but the shape of the weight main body 42 is not particularly limited. That is, for example, a weight body 42 having a substantially inverted truncated cone shape with a diameter reduced downward may be used. Here, in order to improve the seismic sensitivity of the seismic body 41, the center of gravity of the weight body 42 of the seismic body 41 is preferably positioned above the center in the vertical direction.
