It is supported by a drive spring post (upper) 25 provided. The drive spring 22 is a tension coil spring, but a torsion coil spring may be used. A torsion portion is attached to the support shaft 19 of the rotating plate 18 and one end of the torsion coil spring is connected to the drive spring 22. What is necessary is just to hold | maintain at the base 17 and hold | maintain the other end of a torsion coil spring in the rotating plate 18. FIG. In the embodiment of the tension coil spring, the drive spring 22 can be attached to the rotating plate 18 even after the rotating plate 18 is attached, and the assembly is easy.

  A hook portion 27 is formed on the stopper arm 28 so as to be engaged with a stopper 26 provided on the rotating plate 18 while being pivotally supported by the rotating plate 18 and biasing the drive spring 22.

  The stopper arm 28 is formed of a thin metal plate, and an opening 28a is loosely fitted on a stopper arm shaft 29 erected on the base 17 so as to be swingably supported.

  The stopper arm 28 is biased by a return spring 30 in a direction in which the stopper arm 28 presses the stopper 26, and the stopper arm 28 locks the stopper 26. One end of the return spring 30 is supported by a support post 31 provided on the base 17, and the other end is attached to a spring attachment hole 32 provided on the stopper arm 28.

  The stopper arm 28 is in contact with the tip of a push-up bar 33 that pushes up the stopper arm 28 and releases the locking between the stopper arm 28 and the stopper 26.

  The push-up bar 33 is guided by a guide piece 35 of a U-shaped push-up bar guide 34, and the push-up bar guide 34 is fixed to the base 17 by a guide set screw 36. The push-up bar 33 is inserted into a through hole 37 formed in each of the pair of guide pieces 35 of the push-up bar guide 34, and is guided so as to be movable in the vertical direction.

  The push-up bar 33 is erected in the vertical direction at the center position of the thin plate-shaped passive plate 38.

A push-up disk 39 is in contact with the lower surface of the passive plate 38. The passive plate 38 moves up and down following the swing of the push-up disk 39, and pushes up the stopper arm 28 by the push-up bar 33.

  The push-up disk 39 is fixed to the upper end of the suspension shaft 40.

  An L-shaped weight receiving base 41 that supports the suspension shaft 40 in a swingable manner is fixed to the base 17 with mounting screws 42. The suspension shaft 40 is swingably inserted into an opening 43 formed with a diameter larger than that of the suspension shaft 40. A spherical thrust 44 is fixed to the upper middle position of the suspension shaft 40, and the suspension shaft 40 is configured to swing smoothly. The spherical thrust 44 preferably has a shape such that the suspension shaft 40 swings smoothly with respect to the opening 43 such as a hemispherical shape, a spherical shape, or a conical shape.

  The center of a weight 45 that swings due to an earthquake shake is attached to the lower end of the suspension shaft 40. When the weight 45 swings due to an earthquake shake, the passive plate 38 is pushed up in the vertical direction by the push-up disk 39. It is configured. The weight 45 is set to a weight necessary for unlocking.

The adjustment screw 46 is screwed into a screwing piece 47 formed by cutting and raising at the terminal end of the stopper arm 28, and the end of the adjustment screw 46 is adjusted and received by turning the adjustment screw 46 clockwise or counterclockwise. It is possible to adjust the gap between the push-up bar 33 and the stopper arm 28 in contact with the receiving plate piece 49 of the plate 48. Accordingly, by adjusting the gap width between the push-up bar 33 and the stopper arm 28, the operable vertical movement width of the push-up bar 33 changes, and accordingly, the operable push-up width of the push-up disk 11 also changes. The amplitude of the weight 45 fixedly suspended on the push-up disk 39 also changes. If the gap width between the push-up bar 33 and the stopper arm 28 is set narrow, the stopper 26 is pushed up by the push-up bar 8 and the stopper 26 is detached from the hook part 27 even in an earthquake with small shaking. The adjustment receiving plate 48 is supported by a stopper arm shaft 29 erected on the base 17 so that the opening 48a is loosely fitted and swingable.
Therefore, it is possible to adjust the time when the stopper 26 is released from the hook portion 27 due to the shaking of the earthquake. After the adjustment is completed, the nut 50 is tightened so that the adjustment screw 46 is not loosened by the nut 50, and the adjustment is completed.

Further, since the contact point between the top of the push-up bar 33 and the end of the adjustment screw 46 cannot be easily adjusted to one point, the inconvenience is eliminated by providing the adjustment receiving plate 48.
That is, by inserting the receiving plate piece 49 of the adjustment receiving plate 48 between the push-up bar 33 and the adjusting screw 46, the receiving plate piece 49 is displaced even if the position of the adjustment screw 46 and the top of the lifting bar 33 is shifted. 49, the force of the push-up bar 33 is transmitted to the adjustment screw 46, so that the screwing piece 47 to which the adjustment screw 46 is screwed together is integrated with the stopper arm 28, and the stopper arm 28 around the stopper arm shaft 29. The stopper 26 is disengaged from the hook portion 27 because of rotation. If the top of the push-up bar 33 and the top of the adjustment screw 46 are convexly curved in order to improve the sensitivity of shaking, the top of the push-up bar 33 and the top of the adjustment screw 46 cannot be easily aligned at one point. It is effective that the receiving plate piece 49 is formed. However, the receiving plate piece 49 may be provided on the adjustment receiving plate 48 separately from the adjusting screw 46, but a circular adjustment receiving plate is provided at the tip of the adjusting screw 46. The plate 48 may be screwed with screws formed on the adjustment receiving plate 48.

Is pulled.

  As a means for releasing the latch of the stopper 26 from the hook portion 27 provided on the stopper arm 28 due to the occurrence of an earthquake, a suspended spherical thrust 44 having a weight 45 fitted to the suspended shaft 40 due to an earthquake shake is used as a fulcrum. By tilting, the passive plate 38 that is in contact with the upper surface of the push-up disk 39 fixed to the upper end of the suspension shaft 40 is pushed up, and further, the push-up bar 33 fixed in the vertical direction to the center of the passive plate 38 is pushed up in the vertical direction to stop. The stopper arm 28 rotates around the arm shaft 27.

  When the stopper arm 28 rotates, the hook portion 27 provided on the stopper arm 28 releases the stopper 26 pivotally attached to the rotating plate 18, so that the rotating plate 18 is centered on the support shaft 19 by the bias of the drive spring 22. By rotating in the direction of pulling the rope D, the rope D performs towing necessary for unlocking.
