て元に戻しておく。Therefore, when the second connecting rod 65, which will be described in detail later, is assembled to the swing lever 64, the expanding shaft 75c is rotated by a screwdriver so that the sandwiching pieces 75a, 7 are closed.
5a is spread out, and then the second connecting rod 65 is inserted into the corresponding vertical hole of the swing lever 64. After inserting the second connecting rod 65 to the predetermined position, the expanding shaft 75c is of course turned in the opposite direction and returned to the original position.

いことは言うまでもない。In other words, the inner and outer connecting rods 65a and 65b are screwed together. In the illustrated example, a male screw is cut at the lower end of the outer connecting rod 65b and a female screw is cut at the upper end of the inner connecting rod 65a, but it goes without saying that these male screw and female screw may be provided in reverse to each other.
【0029】ここで重要なことは、内連杆65aは上下
方向(長さ方向)には摺動可能にしてあるが、軸線の回
りには回動不能にしてあることである。What is important here is that the inner connecting rod 65a is slidable in the vertical direction (longitudinal direction), but is not rotatable about the axis.
【0030】図示例では、内連杆65aの一部の横断面
を小判形その他の非円形に形成し、その非円形部分65

い。Incidentally, the inner connecting rod 65a and the outer connecting rod 65b described above.
Each does not need to be made of one rod.
For example, two rods may be integrally connected by a pin 95, as in the outer connecting rod 65b clearly shown in FIG.

The gap between 0 and the door 10 is reduced so that the projection piece 5 on the door frame 20 has the first vertical connecting rod 61 or the first horizontal connecting rod 62 in the interlocking mechanism 6.
Since the outer end of the holding member is pressed, the pair of holding pieces 44 of the restricting means 4 is provided through the cam 63, the swing lever 64, the holding pieces 75a and 75a of the mounting device 75, and the second connecting rod 65.
The proximal side of 44 is pushed.

得る。Therefore, even if the locking rod 12 is in the protruding state, the locking rod 12 is pulled into the door 10 together with the lock box 1 at the initial stage of the deformation of the door frame 20, so that a strike or lock is generated. It is possible to prevent the locking rod 12 from being stuck in the strike on the door frame 20 due to the deformation of the box or the locking rod itself.

In order to bring the clamping pieces 44, 44 into contact with the base end side, the tool engaging portion 65 of the outer connecting rod 65b of the second connecting rod 65 is attached.
By locking a driver or the like to f and turning it clockwise or counterclockwise, the total length of the second connecting rod 65 changes depending on the screwing means 65c between the inner connecting rod 65a and the outer connecting rod 65b. Therefore, the adjustment work can be performed extremely easily.

材の寸法の設定により種々変化することは勿論である。The anti-vibration lock according to the present invention is characterized in that the amount of deformation of the door frame due to an earthquake is determined by the interlayer displacement angle defined by the Building Standards Law, that is, when the door is viewed from the front, the horizontal direction of the horizontal frame of the door frame. When the displacement amount is expressed by the length of the vertical frame (radian), it goes without saying that the radian of the interlayer displacement angle at which the operation starts varies variously depending on the setting of the size of each component.

とが可能である。Given the general performance example of this anti-vibration lock, however, when the gap between the door and the door frame, so-called dust, is set to a normal value, it operates at an interlayer displacement angle of 1/225 radian. On the other hand, at the interlayer displacement angle up to 1/150 radian, it is possible to return the lock box moved by the earthquake to the original position.

く、安全性を高める上で極めて有効である。。According to the anti-vibration lock of the present invention described above, even if the door frame or the door is slightly deformed in the closed state in the event of an earthquake, the locking rod is caught on the strike or the lock box. Since it cannot be displaced, the door cannot be opened, which is extremely effective in improving safety. .
