By engaging with the locking edge (locked part), There are things to prevent the jumping out of the drawer body from the furniture body.

  This seismic latch device may not be able to release the fixed state with the first latch body and the second latch body projecting due to some influence such as distortion of the furniture body after the vibration due to the earthquake has subsided. There is one in which a drawer can be pulled out by making it possible to remove a latch receiving member having a stop edge from the drawer (for example, see Patent Document 1).

Japanese Patent Laying-Open No. 2006-200214 (page 18, FIG. 1)

  However, in the earthquake-resistant latch device described in the above-mentioned Patent Document 1, the engagement state between the latch body and the locking edge can be released by removing the latch receiver from the drawer body. In addition, it is difficult to remove the latch holder in the state, and in order to prevent the drawer from popping out from the furniture body again, the latch holder must be attached to the drawer, so it is very difficult to attach and remove the latch holder. There was a problem of being troublesome.

  The present invention has been made paying attention to such a problem, and even if the locking portion and the locked portion are locked after the vibration is stopped, the locking state can be easily released. It is an object of the present invention to provide an earthquake-resistant latch device that can move a drawer.

In order to solve the above-mentioned problem, an earthquake-resistant latch device according to claim 1 of the present invention is provided.

To do.

  Reference numeral 1 in FIG. 1 denotes a cabinet as furniture in the present embodiment having a plurality of drawers 2 to which the earthquake-resistant latch device 6 of the present invention is applied. The earthquake-resistant latch device 6 moves the drawer 2 forward. By being regulated, the drawer 2 housed in the cabinet 1 is prevented from popping out due to vibration caused by the occurrence of an earthquake or the like.

  Hereinafter, the direction in which the drawer 2 is pulled out from the cabinet 1 is the front side (front side), and the storage direction in which the drawer 2 is pushed into the cabinet 1 for storage is the back side (rear side). The right side of the cabinet 1 in the front view will be described as the right side in the present embodiment, and the left side of the cabinet 1 in the front view will be described as the left side in the present embodiment.

  The cabinet 1 is composed of a top plate 3 and side plates 4 provided on the left and right sides of the drawer 2, and a plurality of drawers in the vertical direction between the side plates 4 and 4 (three in this embodiment). 2 is stored. These drawers 2 are substantially rectangular parallelepiped boxes that open upward, and the left and right side plates 5 and 5 are supported by slide rails (not shown) provided on the side plates 4 and 4 of the cabinet 1 on the left and right sides. The housing 1 is provided so as to be movable between a storage position stored in the main body of the cabinet 1 and a drawing position drawn to the front side.

  As shown in FIG. 1, a latch receiver 7 made of a synthetic resin material is provided at the right side front end of the right side plate 5 of the drawer 2, and as shown in FIG. 2, the side plate 4 of the cabinet 1. An embedded recessed portion 8 that opens toward the left side is formed at the front end portion of the left side surface, and a latch body 9 made of a synthetic resin material is embedded in the embedded recessed portion 8.

  The latch receiver 7 and the latch main body 9 are arranged so as to face each other in a state where the drawer 2 is stored in the storage position, and constitutes the earthquake-resistant latch device 6 in the present invention. The seismic latch device 6 is provided between all the drawers 2 shown in FIG. 1 and the side plate 4 of the cabinet 1 main body. However, in the present embodiment, the uppermost drawer 2 and the cabinet 1 have the same configuration. The earthquake-resistant latch device 6 provided between the side plates 4 will be described. Further, in this embodiment, the seismic latch device 6 is described as being provided between the right side plate 5 of the drawer 2 and the right side plate 4 of the cabinet 1, but the seismic latch device 6 is provided as a drawer. 2 may be provided on both the left and right sides.

  As shown in FIGS. 2 and 3, the latch body 9 constituting the earthquake-resistant latch device 6 has a case body 10 embedded in the embedded recess 8. The case body 10 is formed with a storage recess 11 that opens toward the left side. As shown in FIG. 3B, the storage recess 11 is formed in a substantially rectangular shape when viewed from the side, and a shaft support hole 12 that faces in the vertical direction is formed at the rear of the lower surface of the storage recess 11. Further, pivot support holes 13, 13 penetrating the case body 10 in the vertical direction are formed in the front end portions of the upper surface and the lower surface of the storage recess 11.

  Of these shaft support hole 12 and pivot support holes 13, 13, a vibration sensing body 14 that swings with vibration during an earthquake is inserted into the shaft support hole 12. Specifically, the vibration sensing body 14 is a weight body formed in a substantially inverted triangular shape when viewed from the side so that the center of gravity is located at the upper part, and the shaft part 15 projects downward from the lower part. By inserting the shaft portion 15 into the shaft support hole 12, the vibration sensing body 14 is housed in the housing recess 11. Since the diameter of the shaft portion 15 of the vibration sensing body 14 is formed to be smaller than the diameter of the shaft support hole 12, the vibration sensing body 14 swings back and forth and right and left around the shaft portion 15 in the housing recess 11. It is possible to move.

  The storage recess 11 in which the vibration sensing body 14 is stored constitutes a locking portion 16 whose rear end abuts on a locked portion 26 described later, and an outer shape is formed in a complementary shape of the storage recess 11. The locking member 17 is accommodated. A through hole 18 penetrating in the vertical direction is formed at the front end of the locking member 17. Then, the upper and lower ends of the pin 19 inserted through the through hole 18 are pivotally supported by the upper and lower pivot support holes 13, 13, whereby the locking member 17 is stored in a position where the locking portion 16 is not locked. Between the inside of the recess 11 (position indicated by the solid line position in FIG. 2) and the outside of the storage recess 11 (the position indicated by the two-dot chain line in FIG. 2), which is the locking position of the locking portion 16 in the present embodiment, The rear end side is swingable in the left-right direction with the pin 19 facing in the up-down direction as the central axis.

  Further, as shown in FIG. 2, the right side surface of the locking member 17 is formed in a swing receiving portion 20 that is curved to the left, and the swing receiving portion 20 and the storage recess 11 provide a feeling. It is formed so as to sandwich the vibrator 14. The swing receiving portion 20 has a curved surface 21 on the rear end side that is curved leftward toward the front, and an inclined surface 22 on the front end portion side that is tilted leftward from the front to the rear. For this reason, when the cabinet 1 vibrates due to the occurrence of an earthquake or the like, the vibration sensing member 14 swings in the front-rear direction, and alternately presses the curved surface 21 and the inclined surface 22, thereby disengaging the locking member 17. It is pushed out from the stop position and swings (moves) to the lock position.

  As shown in FIGS. 3A and 3B, the left side surface 23 of the locking member 17 has a belt-like non-contact surface 23a extending in the front-rear direction, which is the moving direction of the drawer 2, and a contacted surface. It is comprised from the surface 23b. The abutted surface 23b is a position below the non-abutting surface 23a and extends in parallel with the non-abutting surface 23a from the locking portion 16 toward the front, and is non-inclined from the front side toward the rear side. It is provided so as to be gradually recessed toward the inner side, that is, the right side with respect to the contact surface 23a (see FIG. 4), thereby forming a step portion 23c between the non-contact surface 23a and the contacted surface 23b. A protrusion 27 described later comes into contact.

  Next, as shown in FIG. 2, the latch receiver 7 constituting the earthquake-resistant latch device 6 has a synthetic resin receiving plate 24 that is long in the front-rear direction. A locking screw 25 for locking the receiving plate 24 to the side plate 5 of the drawer 2 is provided on the right side surface of the receiving plate 24, that is, the front end of the surface facing the locking member 17. The latch receiver 7 is attached to the side plate 5 by rotating with respect to the side plate 5.

  Further, as shown in FIGS. 2 and 3A, a locked portion 26 extending in the vertical width direction of the receiving plate 24 is directed toward the locking portion 16 at the rear end portion of the right side surface of the receiving plate 24. Projected. The locked portion 26 is formed to be slightly longer than the vertical length of the locking portion 16 and comes into contact with the locking portion 16 of the locking member 17 disposed at the locking position. The forward movement of the drawer 2 provided with the latch receiver 7 is restricted by the locking of the locked portion 26 by the locking portion 16.

  Between the locking screw 25 and the locked portion 26 at the lower right side of the receiving plate 24, a protrusion 27 is provided as a contact portion that contacts the contacted surface 23b. The protrusion 27 is formed in a spherical shape protruding from the right side surface of the receiving plate 24 toward the locking portion 16.

  That is, the spherical protrusion 27 contacts the contact surface 23b when the drawer 2 is pulled forward (see FIG. 4A), and the drawer is housed in the cabinet 1. The rear abutting surface 29 is in contact with the abutted surface 23b (see FIG. 5A). More specifically, the front contact surface 28 is a curved inclined surface that gradually inclines toward the contacted surface 23b from the front to the rear, and the rear contact surface 29 is directed from the rear to the front. It is a curved inclined surface that gradually inclines toward the contacted surface 23b. That is, it is formed in an inclined shape that is inclined to the left and right with respect to the moving direction (front-rear direction) of the drawer 2.

  As shown in FIG. 2, the protrusion 27 is located in the vicinity of the rear side of the locking portion 16 on the right side surface of the receiving plate 24 in the state where the drawer 2 is in the storage position where the drawer 2 is stored in the cabinet 1. It is disposed at a position ahead of the portion 26 and at a position behind the locking portion 16 of the locking member 17. Further, in the vertical direction, as shown in FIGS. 3A and 3B, it is disposed at substantially the same height position as the abutted surface 23 b formed on the locking member 17, and before and after the drawer 2. By movement, it moves along the abutted surface 23b.

  Further, as shown in FIG. 3A, the protruding length of the protrusion 27 from the right side surface of the receiving plate 24 is substantially the same as the protruding length dimension L of the locked portion 26 from the right side surface of the receiving plate 24. It is formed in length.

  In the present embodiment, the protrusion 27 is disposed in the vicinity of the rear side of the locking portion 16 in a state in which the drawer 2 is in the storage position. The rear side of the locking portion 16 is not necessarily the rear position of the contact position or the contact position where the locking portion 16 can be moved toward the non-locking position by contacting the contacted surface 23b. It does not have to be arranged in the vicinity. In other words, when the abutted surface 23b for moving the locking portion 16 to the non-locking position is formed at a position ahead of the locking portion 16 as in this embodiment, the drawer 2 is in the storage position. In the state, the protrusion 27 may be disposed in front of the locking portion 16.

  Further, when the locking portion 16 is in the non-locking position, the top of the protrusion 27 and the contacted surface 23b are separated by a predetermined distance, so that the protrusion 27 is engaged when an earthquake occurs, as will be described later. Even when passing through the stopper 16 and the contacted surface 23b, the locking member 17 can swing slightly toward the locking position, so that the locking portion 16 is engaged immediately after the projection 27 has passed forward. It can move instantaneously to the stop position.

  As described above, the seismic latch device 6 is arranged so that the locked portion 26 is disposed at a rear position spaced a predetermined distance from the locking portion 16 in a state where the drawer 2 is in the storage position. The locking part 16 moves from the non-locking position to the locking position so that it can be securely locked before 2 is moved forward and the locked part 26 passes through the locking part 16. .

  Next, the operation of the earthquake-resistant latch device 6 in the embodiment of the present invention will be described with reference to FIGS.

  First, in a normal time when no earthquake or the like occurs (non-earthquake), as shown in FIG. 5B, the locking member 17 is retracted to the non-locking position, so the drawer 2 is pulled out. At this time, the locking portion 16 is not locked to the locked portion 26, and the drawer movement is not restricted.

  Next, when vibration is generated in the cabinet 1 due to the occurrence of an earthquake or the like, as described above, the vibration sensing member 14 swings in the front / rear and left / right directions, so that the locking member 17 is moved to the unlocked position and the locked position. And the drawer 2 is moved forward by swinging back and forth (see FIG. 4A).

  When the protrusion 27 moves forward by the forward movement of the drawer 2 and reaches the locking portion 16, as shown in FIG. 4A, the contacted surface of the locking member 17 located at the locking position The front contact surface 28 of the projection 27 contacts the rear end of 23b. At this time, in accordance with the forward movement of the drawer 2, the abutted surface 23b is smoothly moved toward the non-engagement position by the front abutment surface 28 against the urging force of the vibration sensing body 14 in the engagement position direction. Therefore, the forward movement of the drawer 2 is not restricted. In other words, the locking member 17 cannot move to the locking position when the protrusion 27 is positioned and abutted against the contacted surface 23b, and the swinging width in the left-right direction is reduced.

  As the protrusion 27 further moves forward together with the drawer 2 from this state, the separation width between the locking member 17 and the contacted surface 23b gradually increases, so that the rocking width of the locking member 17 gradually increases, By the time the locking part 26 reaches the locking part 16, the locking part 16 can move to the locking position again. Therefore, when the locked portion 26 reaches the locking portion 16, the forward movement of the drawer 2 is restricted by locking the locked portion 26 to the locking portion 16 located at the locking position ( Since the drawer 2 is prevented from jumping out, it is safe.

  As shown in FIG. 4B, in the locked state where the locked portion 26 is locked to the locking portion 16 located at the locking position and the forward movement of the drawer 2 is restricted, the protrusion 27 Is opposed to the abutted surface 23b that is recessed with respect to the upper non-abutting surface 23a, so that the abutting surface 23a is not abutted and is slightly separated, Since the protrusion 27 does not interfere with the locking member 17, the locking portion 16 can be reliably moved to the locking position and the locked portion 26 can be locked.

  After the drawer 2 is restricted from being drawn forward, when the vibration due to an earthquake or the like is settled and the normal use, it is necessary to release the restriction of the drawer 2, so as shown in FIG. Push it back so that it is housed in the cabinet 1. By this operation, the protrusion 27 that has moved forward from the locking portion 16 moves back again, and the rear contact surface 29 contacts and presses against the contacted surface 23b, so that the locking member 17 It moves toward the non-locking position and is accommodated in the case body 10 (see FIG. 5B).

  At this time, by pushing the drawer 2 while urging it backward, the protrusion 27 collides (contacts) with the contacted surface 23b, and flips the locking member 17 toward the non-locking position. Even if the protrusion 27 does not completely push into the non-locking position while being in contact with the contacted surface 23b, the locking member 17 is reliably accommodated in the non-locking position in the case body 10.

  In this way, by a simple operation of simply storing the drawer 2 in the cabinet 1, the locking member 17 comes into contact with the protrusion 27 and is pressed to return to the non-locking position, so that the locking portion 16 is locked. Since it does not contact the portion 26, the drawer 2 can be put into and out of the cabinet 1 main body.

  For example, when a weak earthquake occurs or the locking member 17 is slightly swung to the locking position side for some reason during normal times when no earthquake or the like occurs, the drawer 2 is in the storage position. Therefore, the protrusion 27 may remain at a position behind the locking portion 16 (see FIG. 4A). In this case, by pulling out the drawer 2 forward, the front contact surface 28 of the protrusion 27 disposed rearward of the locking portion 16 is not engaged while the locking member 17 is slidably contacting the contacted surface 23b. By pressing toward the stop position, it is possible to avoid the locking portion 16 from coming into contact with the locked portion 26, so that the drawer 2 can be pulled out.

  As described above, in the cabinet 1 as an embodiment to which the present invention is applied, when the cabinet 1 vibrates due to an earthquake or the like, the locking portion 16 moves from the non-locking position to the locking position, and the locked portion 26 can be locked, and the forward movement of the drawer 2 due to vibration is restricted. However, in the locked state where the locked portion 26 is locked to the locking portion 16, the protrusion 27 is locked to the locking portion 16. It will be located in front of. Therefore, for example, even if the locking portion 16 is positioned at the locking position after an earthquake or the like is settled, the protrusion 27 comes into contact with the locking portion 16 only by pushing or pulling out the drawer 2 in the storing direction. Since 16 is moved from the locking position to the non-locking position, the locked state can be reliably released by a simple operation.

  The protrusion 27 has a front contact surface 28 that contacts the locking portion 16 when the drawer 2 moves forward, and the front contact surface 28 is inclined so as to be inclined with respect to the moving direction of the drawer 2. 4A, when the drawer 2 moves forward as shown in FIG. 4A, the projection 27 is less likely to be caught by the locking portion 16, and the locking portion 16 is smoothly unlocked. Since it is moved toward the position, there is no possibility that the drawer 2 cannot be pulled out.

  Further, the abutted surface 23b with which the protrusion 27 in the locking portion 16 abuts is recessed on the inner side (right side) than the non-contact surface 23a constituting the top of the locking portion 16, Since the abutting depth with the protrusion 27 is shallower on the abutted surface 23b than the locking portion 16, the protrusion 27 is not easily caught by the locking portion 16 when the drawer 2 moves forward due to vibration. Even when the protrusion 27 is in contact with the contacted surface 23b, the locked portion 26 can be locked to the locking portion 16, so that the locked portion 26 is attached to the locking portion 16. It can be surely locked.

  Further, since a step 23c is formed between the contacted surface 23b and the non-contact surface 23a of the locking portion 16, the protrusion 27 comes into contact with the step 23c by raising the front part of the drawer 2, and this Thus, the locking portion 16 can be pushed further toward the non-locking position, so that the locked state can be reliably released.

  Further, since the protrusion 27 is a spherical protrusion protruding toward the locking portion 16, the protrusion 27 is less likely to be caught on the locking portion 16 when the drawer 2 is put in and out, so that the locking portion 16 can be smoothly moved. Therefore, there is no possibility that the drawer 2 cannot be pulled out.

  Further, since the projection 27 is formed at substantially the same position as the top (tip) of the locked portion 26 (or lower than the top (tip) of the locked portion 26), the projection 27 connects the locking portion 16. Since it does not move toward the non-locking position more than necessary, it is possible to prevent a malfunction that the locking portion 16 does not come into contact with the locked portion 26.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the above embodiment, the latch receiver 7 having the locked portion 26 is provided on the side plate 5 of the drawer 2, and the latch body 9 having the locking portion 16 is provided on the side plate 4 of the cabinet 1. As in the modification shown in FIG. 6, the latch main body 9 may be provided on the side plate 5 of the drawer 2 and the latch receiver 7 may be provided on the side plate 4 of the cabinet 1. Specifically, the locking member 17 is pivotally supported on the right side surface of the side plate 5 of the drawer 2 so as to be swingable in the left-right direction by a pin 19 at the rear end portion in the housing recess 11 of the case body 10. A receiving plate 24 is provided on the left side surface of the side plate 4 of the cabinet 1 so that the locked portion 26 is disposed at the front end. Even if it does in this way, the effect | action and effect similar to the earthquake-resistant latch apparatus of the said Example can be acquired.

  Moreover, in the said Example, although the protrusion 27 was applied as a contact part, the shape of the protrusion 27 is not limited to a spherical thing, It can deform | transform variously. That is, the front contact surface and the rear contact surface are not limited to spherical ones, and may be flat as long as they are formed in an inclined shape. Further, the protrusion 27 does not have to be provided in advance at a predetermined position on the right side surface of the receiving plate 24. For example, only when the locking portion 16 is moved to the non-locking position by a button operation or the like, the locking portion 16 It can be made to project so that it can be locked.

  In the above embodiment, the locking member 17 can be swung between the non-locking position and the locking position by swinging the vibration-sensing body 14 provided on the latch body 9. If the stopping member 17 is movable between the non-locking position and the locking position and is moved to the locking position due to the occurrence of vibration, the vibration sensing body 14 is not necessarily used. Based on the fact that the vibration is detected by vibration sensing means (not shown) that can detect the occurrence of vibration, the locking member 17 is engaged from the non-locking position by driving means (not shown) such as an electromagnetic solenoid. It may be moved (protruded) to the stop position.

  In the above embodiment, the seismic latch device 6 is provided between the side plate 5 of the drawer 2 and the side plate 4 of the cabinet 1 to restrict the forward movement of the drawer 2 during an earthquake.
