The force is converted into a force that causes the engaging surface 33 of the latch body 32 to protrude, which is a direction orthogonal to the moving direction of the latch body 32.

  That is, due to the pressing of the inclined surface 46 of the latch body 32 by the rolling element 31, the elastic force of the winding spring 41 that biases between the latching convex portion 29 of the case body 21 and the latching piece portion 38 of the latch body 32. The engaging surface 33 of the latch body 32 protrudes from the inside of the housing recess 22 of the case body 21 against the force for accommodating the latch body 32 in the housing recess 22 of the case body 21. To do.

  Therefore, the engagement surface 33 of the latch body 32 protruding from the housing recess 22 of the case body 21 is engaged with and locked to the locking edge 57 of the latch receiver 51. For this reason, since the drawer body 3 cannot be pulled out from the furniture body 2 by the engagement of the latch body 32 with the engaging edge 57 by the engagement surface 33, the drawer body 3 from the furniture body 2 due to vibrations cannot be pulled out. Jumping out is prevented.

  As described above, according to the first embodiment, the rolling element 31 of the earthquake-resistant latch 1 rolls along the moving direction of the drawer body 3 during a vibration. As the rolling element 31 rolls, the rolling element 31 comes into contact with one of the inclined surfaces 46 of the latch body 32 inclined. As a result, the force that the rolling element 31 rolls against the inclined surface 25 of the case body 21 is the direction orthogonal to the moving direction of the drawer body 3 by the inclined surface 46 of the latch body 32. The force is converted into a force for projecting the engaging surface 33 of the first member.

  Therefore, the engagement surface 33 of the latch body 32 protrudes from the housing recess 22 of the case body 21 by the rolling of the rolling body 31. Therefore, regardless of the mounting direction of the seismic latch 1 and the latch receiver 51, the engagement surface 33 of the latch body 32 is engaged with the locking edge 57 of the latch receiver 51 due to the rolling of the rolling element 31 during vibration. The drawer body 3 to which the latch receiver 51 is attached is fixed in the furniture body 2.

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

  Further, with respect to the rolling element 31 accommodated in the accommodation recess 22 of the case body 21 so as to be able to roll, the latch body 32 is arranged in parallel at a position orthogonal to the rolling direction of the rolling element 31. Since the latch body 32 and the rolling element 31 can be accommodated in the accommodating recess 22 of the case body 21 more efficiently, the seismic latch 1 can be further downsized.

  Further, by providing the inclined surfaces 46 on both side edges of the rolling receiving portion 45 of the latch body 32, the rolling body 31 rolls in any direction along the moving direction of the drawer body 3, The rolling element 31 abuts on one of the inclined surfaces 46 of the latch body 32. Therefore, the engagement surface 33 of the latch body 32 protrudes from the housing recess 22 of the case body 21 when the rolling element 31 is pressed against the inclined surface 46 of the latch body 32. For this reason, the engaging surface 33 of the latch body 32 can be engaged with the engaging edge portion 57 of the latch receiver 51 regardless of the rolling direction of the rolling body 31, so that the drawer body 3 cannot be pulled out from the furniture body 2. Can be.

  Furthermore, a pair of inclined surfaces 25 inclined upward from the central portion of the rolling element installation portion 23 toward both ends along the longitudinal direction are provided on the rolling element installation portion 23 of the case body 21. As a result, even if the rolling element 31 installed in the rolling element installation unit 23 rolls in any direction along the longitudinal direction of the rolling element installation unit 23 during the earthquake, the rolling element 31 has its own weight. Thus, the rolling element 31 is guided by the pair of inclined surfaces 25 to the center portion between the pair of inclined surfaces 25 when the vibration is stopped. Accordingly, since the rolling element 31 is guided to the normal position between the pair of inclined surfaces 25 when the vibration is stopped, the latch body 32 can be accommodated in the accommodating recess 22 of the case body 21 when the vibration is stopped. The seismic motion of the seismic latch 1 when the vibration is stopped can be released.

  Further, a pair of tapered surfaces 26 inclined upward from the center of the rolling element installation portion 23 to both sides along the width direction are provided on each of the pair of inclined surfaces 25 provided on the rolling element installation portion 23 of the case body 21. Was established. As a result, when the rolling element 31 installed in the rolling element installation portion 23 of the case body 21 rolls during the earthquake, the rolling element 31 is rotated by the pair of tapered surfaces 26 by the weight of the rolling element 31. The rolling element 31 rolls along the longitudinal direction of the rolling element installation part 23 in a state guided by the central part in the width direction of the installation part 23. Therefore, this rolling element 31 can be reliably rolled along the longitudinal direction of the rolling element installation part 23, and the fall from the rolling element installation part 23 at the time of rolling of this rolling element 31 can be prevented.

  Further, a winding spring 41 is attached between the locking projection 29 of the case body 21 and the locking piece 38 of the latch body 32, and the latch body 32 is accommodated in the housing recess of the case body 21 by the elastic force of the winding spring 41. It was set as the structure which energizes in 22 and is accommodated. As a result, when rolling of the rolling element 31 at the time of earthquake recovery returns, the protrusion of the latch body 32 from the case body 21 is released by the elastic force of the winding spring 41, and the latch body 32 is It is securely housed in the housing recess 22.

  For this reason, the engagement of the latch receiving member 51 by the engagement surface 33 of the latch body 32 with the locking edge 57 is released by the urging force of the winding spring 41. Therefore, since the return operation, which is the release of the seismic action of the earthquake-resistant latch 1 when the vibration is stopped, can be assisted by the elastic force of the winding spring 41, the release of the earthquake-resistant action of the earthquake-resistant latch 1 when the vibration is stopped is more reliably performed it can.

  That is, by the elastic force of the winding spring 41, 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. The stop state of the drawer 3 can be released by the movement in the initial state. Furthermore, the rolling element 31 is pressed by the inclined surface 46 of the latch body 32 when the vibration is stopped by the elastic force of the winding spring 41, and the rolling element 31 is guided to the normal position on the rolling element installation portion 23. . Accordingly, the elastic force of the winding spring 41 can assist the returning operation of the rolling element 31 when the vibration is stopped.

  Furthermore, by providing the rolling element installation portion 23 on each of the upper side surface and the lower side surface of the accommodation recess 22 of the case body 21, even if the case body 21 is installed upside down, the accommodation recess of the case body 21 Any one of the rolling element installation portions 23 of 22 can roll the rolling element 31 along the pull-out direction at the time of vibration.

  Accordingly, even if the seismic latch 1 is mounted upside down, the latch body 32 of the seismic latch 1 is pressed by the rolling body 31 and protrudes during the vibration and engages with the locking edge 57 of the latch holder 51. . As a result, since the seismic latch 1 of the same product can be made common to the left and right or up and down, the mounting direction of the seismic latch 1 can be easily changed, so that the usability of the seismic latch 1 can be improved.

  Note that, as in the second embodiment shown in FIG. 7, the latch body 32 is placed in the housing recess 22 of the case body 21 by utilizing the gravity acting on the latch body 32, that is, the own weight of the latch body 32. It can also be set as the structure biased so that it may be accommodated. In this case, an annular engagement protrusion 61 is provided at the opening edge of the shaft stopper hole 28 provided on the lower surface side of the housing recess 22 of the case body 21 on the housing recess 22 side. The engaging protrusion 61 is provided on the lower side surface located on the lower side of the housing recess 22 and is provided concentrically with the shaft stop hole 28 on the lower surface side of the housing recess 22.

  Further, the engaging protrusion 61 includes a flat portion 62 that is flat along the lower surface of the housing recess 22. The flat portion 62 is formed in an approximately half region which is a part of the engaging protrusion 61 close to the front end side and the opening side of the housing recess 22. Further, one end portion of the flat portion 62 is provided with a vertical surface portion 63 that is a vertical surface protruding vertically upward from the flat portion 62. The vertical surface portion 63 is positioned on the opening side of the housing recess 22 of the case body 21 and is a vertical surface along the vertical direction that is the height direction of the housing recess 22.

  Further, a part of the engaging protrusion 61 located inside the accommodating recess 22 with respect to the vertical surface part 63 has a flat horizontal surface part 64 protruding upward from the flat part 62 of the engaging protrusion 61. Is provided. The horizontal surface portion 64 is formed in parallel to the flat portion 62 of the engaging protrusion 61, and is formed in a partial region of the engaging protrusion 61 close to the rear end side and the inside of the housing recess 22. ing.

  An inclined surface portion 65 is formed between the horizontal surface portion 64 and the flat portion 62 as a connection surface that connects the horizontal surface portion 64 and the flat portion 62. The inclined surface portion 65 is an inclined surface inclined downward from the horizontal surface portion 64 side toward the flat portion 62 side, and is provided at a position substantially opposite to the vertical surface portion 63 of the engaging projection 61. That is, the inclined surface portion 65 is inclined toward the rotation direction of the latch body 32.

  Further, an engaged protrusion 66 having a shape corresponding to the engagement protrusion 61 of the case body 21 is provided on the lower surface of the latch body 32 in the vertical direction which is the width direction. The engaged protrusion 66 is a semicircular arc-shaped protrusion concentrically provided at the opening edge of the shaft insertion hole 35 penetrating to the lower surface of the latch body 32. The engaged protrusion 66 includes a flat portion 67 that comes into contact with the flat portion 62 of the engaging protrusion 61 of the case body 21.

  Near the rear end of the flat portion 67, it abuts on the inclined surface portion 65 of the engaging projection 61 of the case body 21, and the latch body 32 is slidably contacted into the housing recess 22 of the case body 21 by its own weight. A sliding contact surface portion 68 is formed as a sliding contact portion to be slid. The sliding contact surface portion 68 presses the inclined surface portion 65 of the case body 21 by the gravity acting on the latch body 32, that is, the action due to the weight of the latch body 32, thereby slidingly contacting the inside of the housing recess 22 of the case body 21. The latch body 32 is accommodated. At this time, the sliding contact surface portion 68 and the inclined surface portion 65 are such that the force for housing the latch body 32 in the housing recess 22 of the case body 21 is smaller than the force by which the rolling element 31 presses the latch body 32 during the earthquake. In addition, the inclination angles of the sliding contact surface portion 68 and the inclined surface portion 65 are set.

  Here, the engaged protrusion 66 constituted by the flat portion 67 and the sliding contact surface portion 68 is an urging mechanism as an urging means for urging the latch body 32 toward the inside of the housing recess 22 of the case body 21. Part of 69. And this urging mechanism 69 is such that the engagement surface 33 of the latch body 32 is opposite to the protruding direction, and the engagement surface 33 of the latch body 32 is accommodated in the accommodation recess 22 of the case body 21. The latch body 32 is configured to be biased.

  As a result, the sliding contact surface portion 68 of the latch body 32 is brought into contact with the inclined surface portion 65 of the case body 21, and the latch body 32 is directed toward the inside of the housing recess 22 of the case body 21 by the weight of the latch body 32. Accordingly, when the rolling element 31 is restored, the latch body 32 is securely accommodated in the accommodating recess 22 of the case body 21, and the returning operation of the rolling element 31 is controlled by the latch body 32. Since it is assisted by pressing by, it is possible to achieve the same operational effects as in the first embodiment.

  Further, the sliding contact between the inclined surface portion 65 of the case body 21 and the sliding contact surface portion 68 of the latch body 32 allows the latch body 32 to be forcibly accommodated in the housing recess 22 when the vibration is stopped. Thus, the protrusion of the engagement surface 33 of the latch body 32 is released when the rolling body 31 returns to rolling without attaching an urging means such as a winding spring 41 between the case body 21 and the latch body 32. Thus, the engagement of the latch receiving member 51 with the engaging edge 33 of the latch body 32 is released.

  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 with a simple configuration in which the inclined surface portion 65 is provided in the case body 21 of the earthquake resistant latch 1 and the sliding contact surface portion 68 is provided in the latch body 32.

The latch body 32 may be pressed against the inclined surface portion 65 of the case body 21 and urged toward the housing recess 22 of the case body 21.

  That is, when the rolling element 31 rolls to a steady position between the pair of inclined surfaces 25 of the case body 21 when the vibration is stopped, the coil spring causes the latch body 32 to move to the case body by the elastic force of the coil spring. The engagement surface 33 of the latch body 32 is housed in the housing recess 22 of the case body 21 by rotating toward the 21 side. Therefore, the coil spring releases the engagement of the latch receiving member 51 with the engagement edge portion 57 by the engagement surface 33 of the latch body 32 and allows the drawer body 3 to be pulled out from the furniture body 2.

  As a result, even when the earthquake-resistant latch 1 is turned upside down, the latch body 32 can be 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. Therefore, even if the seismic latch 1 is turned upside down, the seismic latch 1 can be restored by the elastic force of the coil spring when the seismic motion is stopped, so that the usability of the seismic latch 1 can be improved.

  Here, the latch body 32 is biased toward the inside of the housing recess 22 of the case body 21 by the elastic force of the coil spring. However, the latch body 32 is biased by a biasing means such as a leaf spring other than the coil spring. Can be directly urged toward the inside of the case body 21.

Further, the seismic latch 1 is attached to the inner rail 72 of the slide rail 71, and a cut-and-raised piece portion 94 is provided on the outrail 73 of the slide rail 71, and the locking edge 57 of the cut-and-raised piece portion 94 is latched. The configuration is such that the engagement surfaces 33 are engaged with each other.

  For this reason, since the seismic latch 1 can be attached between the furniture body 2 and the drawer body 3 only by attaching the slide rail 71, compared to the case where the seismic latch 1 is separately attached to the furniture body 2 or the drawer body 3, this earthquake resistance. The attachment work of the latch 1 can be simplified.

  Further, the latch body 32 of the seismic latch 1 is energized by the elastic force of the winding spring 41 so that the latch body 32 is accommodated in the case body 21, and the housing recess 22 of the case body 21 of the seismic latch 1 and the lid body are energized. A rolling element installation part 23 is provided on each of the back surface of 85 and the rolling element installation part 23 is made to face each other. As a result, even if the seismic latch 1 is turned upside down, the latch body 32 protrudes from the case body 21 due to the rolling of the rolling element 31 during the earthquake and is latched by the elastic force of the winding spring 41 during the non-earthquake. The body 32 is accommodated in the case body 21. Therefore, the seismic latch 1 can be turned upside down and attached to the slide rail 71.

  Further, the case body 21 in which the latch body 32 of the earthquake-resistant latch 1 is accommodated is formed on the inner rail 72 itself as a fixing member, and the cut-and-raised piece portion 94 with which the latch body 32 engages is provided on the outrail 73 and moved. It can also be a member.

  Further, as in the fourth embodiment shown in FIGS. 11 and 12, the movement of the rectangular flat sliding door body 101 as a movable member movable in the width direction is fixed by the earthquake-resistant latch 1 at the time of vibration. It can also be configured. In this case, the sliding door body 101 is slidably attached between the upper guide rail 102 and the lower guide rail 103. Further, the sliding door body 101 is fixed by the seismic operation of the seismic latch 1 so that the sliding door body 101 moves in the width direction when the seismic motion is felt.

  At this time, the upper guide rail 102 functions as a fixed member, and the sliding door body 101 functions as a moving member. The upper guide rail 102 includes a plurality of, for example, two travel recesses 104 formed along the longitudinal direction of the upper guide rail 102 as shown in FIG. These running recesses 104 are arranged in parallel to each other, and each of these running recesses 104 opens downward.

  The earthquake-resistant latch 1 is attached inside the upper guide rail 102 so that the engaging surface 33 of the latch body 32 protrudes into each traveling recess 104 of the upper guide rail 102 during vibration. That is, these seismic latches 1 are attached so that the engaging surface 33 of the latch body 32 protrudes below the lower surface of the case body 21 of the seismic latch 1.

  Further, these seismic latches 1 are mounted on the respective traveling recesses 104 in the upper guide rail 102. Therefore, these seismic latches 1 cause the engaging surfaces 33 of the latch bodies 32 to move into the respective running recesses 104 of the upper guide rail 102 by swinging of the rolling elements 31 along the moving direction of the sliding door body 101 of these seismic latches 1. And protrude.

  On the other hand, a pair of pivot shafts 106 that are latch receiving members serving as locking body receiving members protrude from the upper end surface of each sliding door body 101. These pivot shafts 106 are moving members and are shaft bodies serving as locked portions that are locked to the engaging surfaces 33 of the latch bodies 32 that protrude when the seismic latch 1 is sensed. Further, these pivot shafts 106 are attached at positions spaced from the central portion of the upper end surface of the sliding door body 101 at equal intervals in the longitudinal direction of the upper end surface.

  The pivot shafts 106 are fitted in the running recesses 104 of the upper guide rail 102 so that they can run and slide. Therefore, these pivot shafts 106 come into contact with the engaging surface 33 of the latch body 32 by the protrusion of the engaging surface 33 of the latch body 32 into the traveling recess 104 by the seismic operation of the earthquake-resistant latch 1, and the sliding door body. The movement of the 101 along the upper guide rail 102 is fixed.

  Furthermore, a guide roller 107 as a moving member that is rotatable along the moving direction of the sliding door body 101 is attached to the lower end portion of each sliding door body 101. The guide roller 107 functions as a latch receiver as a locking body receiver. Further, the guide roller 107 is attached to a position spaced from the central portion of the lower end surface of the sliding door body 101 at equal intervals in the longitudinal direction of the lower end surface.

  These guide rollers 107 are fitted in a travel groove portion 108 provided on the upper side surface of the lower guide rail 103 so as to travel. These running groove portions 108 are formed in a concave groove shape along the longitudinal direction of the lower guide rail 103. Further, the travel groove portions 108 are provided at positions facing the travel recesses 104 of the upper guide rail 102.

  And, in this lower guide rail 103, an earthquake-resistant latch 1 is mounted for projecting the engaging surface 33 of the latch body 32 into each running groove portion 108 of the lower guide rail 103 during vibration. These seismic latches 1 have the same shape as that of the seismic latch 1 mounted in the upper guide rail 102, and the seismic latch 1 is turned upside down so as to be housed and mounted in the lower guide rail 103.

  That is, these seismic latches 1 are attached such that the engagement surface 33 of the latch body 32 protrudes above the upper surface of the case body 21 of the seismic latch 1. Further, these earthquake-resistant latches 1 are attached to the lower side of the traveling groove portions 108 in the lower guide rail 103. Therefore, these seismic latches 1 cause the engaging surfaces 33 of the latch bodies 32 to move into the respective running grooves 108 of the lower guide rail 103 by the swinging of the rolling elements 31 along the moving direction of the sliding door body 101 of these seismic latches 1. And protrude.

  As a result, when rolling vibration that is the moving direction of each sliding door body 101 occurs, the rolling element 31 of each earthquake-resistant latch 1 rolls along the moving direction of the sliding door body 101. The latch body 32 is pressed, and the engagement surface 33 of the latch body 32 is projected into the travel recess 104 of the upper guide rail 102 or the travel groove portion 108 of the lower guide rail 103, so that the engagement surface of the latch body 32 is 33 is configured to be brought into contact with the pivot shaft 106 or the guide roller 107 of each sliding door body 101 and locked.

  For this reason, since the movement in the lateral direction of each sliding door body 101 is fixed by the seismic operation of the earthquake-resistant latch 1, even if the sliding door body 101 is mounted between the upper guide rail 102 and the lower guide roller 103, The same effect as the first embodiment can be obtained.

  In each of the above embodiments, the rolling element 31 is a spherical weight. However, as in the fifth embodiment shown in FIG. 13, the rolling element 31 is a cylindrical weight such as a roller. You can also. In this case, the rolling element 31 is installed on the rolling element installation portion 23 in the housing recess 22 of the case body 21 with the axial direction being along the thickness direction of the case body 21.

  Then, the rolling element 31 rolls along the longitudinal direction of the case body 21 during the vibration and presses one of the inclined surfaces 46 of the latch body 32. Therefore, when the rolling element 31 vibrates, the engaging surface 33 of the latch body 32 protrudes and engages with and engages with the engaging edge 57 of the latch receiver 51, so that the same action as in the above embodiments is achieved. There is an effect.

  Further, although the rolling element setting portions 23 are provided on the upper surface and the lower surface in the accommodating recess 22 of the case body 21, the rolling element mounting portions 23 can be provided on all four surfaces in the accommodating recess 22. Further, the pair of inclined surfaces 25 constituting the rolling surface 24 on the rolling element installation portion 23 is configured by a pair of tapered surfaces 26 having a V-shaped cross section. It can also be comprised by the circular arc surface curved in the shape.

  In this case, a pair of inclined surfaces 25 composed of these circular arc surfaces are connected to form a shape in which the bottom surfaces of the two cones are concentrically connected, or a shape in which the bottom surfaces of the two truncated cones are concentrically connected to each other. A rolling surface 24 having a barrel shape or the like can also be formed in the housing recess 22 of the case body 21.

  Furthermore, the rolling surface 24 on the rolling element installation portion 23 in the case body 21 is configured by a pair of inclined surfaces 25 that incline from both sides toward the center. It is also possible to configure with only one inclined surface 25 inclined along the line.

  Even if the drawer body 3 accommodated in the furniture body 2 or the sliding door body 101 attached between the upper guide rail 102 and the lower guide roller 103 is other than the earthquake-resistant latch 1 for preventing movement during vibration, For example, an earthquake-resistant latch 1 is attached between a hinged door (not shown) that is pivotally supported at one end and an opening (not shown) in which the hinged door is attached so as to be openable and closable. It can also be configured to prevent by the seismic motion.
