  When the locked device 61 is slid to the near side (in the direction of arrow Q), the inclined surface 68a of the guide projection 68 is in sliding contact with the edge 109a of the near side opening 109, and the near side of the locked device 61 is the side wall 107. And can be easily removed from the side wall 107 of the drawer 105. That is, as shown in FIG. 2C, when the locked device 61 is slid forward (in the direction of the arrow Q), as shown in FIG. 67a is disengaged from the end edge 108a of the back side opening 108, the inclined surface 68a of the guide projection 68 is in sliding contact with the end edge 109a of the front side opening 109, the front side of the locked device 61 is separated from the side wall 107, and the locking claw 66 Is disengaged from the peripheral edge 109 b of the front opening 109. When the locked device 61 is slid to the near side (arrow Q direction), the locking claw 66 and the locking recess 67a are unlocked and can be detached from the side wall 107.

  As shown in FIG. 5, the locking device 1 is in contact with one side surface 17 on the connection line (sphere stationary portion) 23 where the sphere 8 is at the lowest position during non-vibration. (Initial position). The locking member 31 is urged downward by its own weight to be in the non-locking position X1, and is accommodated in the storage chamber 11 of the case 2. Accordingly, the drawer 105 can be opened and closed smoothly without any interruption.

  As shown in FIG. 6, the locking device 1 moves from the connection line (sphere stationary portion) 23 where the sphere 8 is the lowest position during vibration. For example, when the sphere 8 moves to the opening 18 side (X direction), the central portion 43 of the curved recess 40 of the locking member 31 is pressed outward, and the locking member 31 rotates about the support shafts 6 and 7. The lower portion 31a protrudes to the locking position X2. When the sphere 8 moves in the direction in which the drawer 105 opens (F direction), the sphere 8 moves while being in sliding contact with the front curved surface 41, so that the locking member 31 is pressed outward and the locking member 31 is moved to the support shaft 6. , 7 as a center, and the lower portion 31a protrudes to the locking position X2. Similarly, when the sphere 8 moves in the direction in which the drawer 105 is closed (direction B), the sphere 8 moves while being in sliding contact with the rear curved surface 42, so that the locking member 31 is pressed outward and the locking member 31 is supported. It rotates about the shafts 6 and 7, and the lower part 31a protrudes to the locking position X2. Even when the sphere 8 is about to move in the vertical direction (Z direction), the movement of the sphere 8 in the vertical direction is restricted by the upper part of the sphere 8 coming into contact with the guide plate 45. However, when a considerably strong vertical vibration occurs, the sphere 8 pushes up the guide plate 45, the locking member 31 rotates about the support shafts 6 and 7, and the upper portion 31b protrudes to the locking position X2. To do.

  Thus, in the locking device 1, the sphere 8 rolls during vibration, the locking member 31 is pushed outward, and the lower portion 31a (or the upper portion 31b) of the locking member 31 moves to the locking position X2. . In the drawer 105, the locked device 61 is mounted on the outer side surface 107a of the right (or left) side wall 107 thereof, so that the locking protrusion 65 of the locked device 61 is attached to the lower portion 31a ( Or it is latched by the upper part 31b), and an opening | release is blocked | prevented (movement to the opening direction is controlled).

  When the vibration is finished, the locking device 1 returns to the connection line (sphere stationary part) 23 along the front inclined surface 21 or the rear inclined surface 22 due to its own weight, and further, the connecting line 23 is lowered. Along one side 17 and stops at the initial position. When the vibration is finished and the sphere 8 returns to the original stationary position, the sphere 8 does not press the locking member 31, so that the lower portion 31 a (or the upper portion 31 b) of the locking member 31 is moved to the original non-locking position by its own weight. Return to X1. The drawer 105 is unlocked from the locking projection 65 of the locked device 61, and the drawer 105 can be moved in the opening / closing direction again.

  The drawer 105 may not automatically return due to some cause, for example, a failure such as the sphere 8 meshing with the locking member 31 and may not open. In such a case, a rod-shaped member such as a screwdriver is inserted into the stepped recess 71 of the locked device 61 from the gap between the storage device main body 101 and the drawer 105, and the locking claw 66 is forced from the peripheral edge 109 b of the front opening 109. By this operation, the locked device 61 can be removed from the side wall 107. If the locked device 61 is removed from the side wall 107 of the drawer 105, the drawer 105 can be opened, so that the above-described obstacles can be solved.

  The present invention can be used as a vibration detection lock device that is provided in a storage device with drawers such as a bag, a desk, a cupboard, etc., and regulates the opening of the drawers during vibration such as an earthquake.
