That is, the sickle part 32 is urged | biased so that it may rotate counterclockwise by using the screw cylinder 30j (sickle part hole 32h) as a fulcrum. In other words, the hook portion 32e of the sickle portion 32 is urged in the opening direction.

Next, the operation of the lock 1 for the telescopic gate according to the embodiment of the present invention will be described. The main body 2 takes the posture shown in FIG. 16 when the main body 2 does not match the strike 3. As described above, the hook portion 32e of the sickle portion 32 is urged in the opening direction. That is, the main body 2 is in the “open state”.
When the main body 2 in the “open state” comes into contact with the strike portion 3, the movement shown in FIGS. More specifically, as shown in FIG. 17A, the rod-shaped portion 12 of the strike portion 3 contacts the contact portion 32 d of the sickle portion 32 of the main body portion 2. When the contact portion 32d is pushed in this state, the hook portion 32e interlocked with the contact portion 32d rotates clockwise around the screw cylinder 30j (sickle portion hole 32h). At this time, the sliding pin 36 a inserted through the holder portion 33 moves up the inclined portion 32 k of the sickle portion 32. When the contact portion 32d is pushed by the rod-shaped portion 12, the sliding pin 36a reaches the tip portion 32j of the sickle portion 32, as shown in FIG. Further, when the contact portion 32d is pushed by the rod-shaped portion 12, as shown in FIG. 17C, the slide pin 36a descends vertically from the tip portion 32j and reaches the contact portion 32d. Since the sliding pin 36a is engaged with the pin 32f by the sickle spring 32i, the sliding pin 36a is pulled downward. As a result, the hook portion 32 e of the sickle portion 32 is biased in the direction in which the rod-like portion 12 of the strike portion 3 is wound. The rod-like portion 12 is firmly locked by the urging force of the sickle portion spring 32i. For this reason, both can be easily locked only by making the main-body part 2 and the strike part 3 correspond. In addition, as shown in FIG. 18, the main-body part 2 will be in a "closed state."

  Next, a method for unlocking the main body 2 from the “closed state” to the “open state” will be described. As shown in FIG. 18, when the lever shaft 34a of the lever hub 34 is rotated counterclockwise in the main body 2 in the “closed state”, the lever hub 34 is counterclockwise with the lever shaft 34a as a fulcrum. Rotate around. Then, the lever foot 34 h of the lever hub 34 presses the sliding pin 36 b inserted through the release hole 33 b of the holder portion 33 in the right direction. When the pressed sliding pin 36b moves to the right end of the lateral hole 30b of the housing 30, the holder part 33 rotates clockwise around the screw cylinder 30h (holder part hole 33c). As the holder portion 33 rotates, the sliding pin 36 a moves to the upper portion of the oblique hole 30 a of the housing 30. When the sliding pin 36a moves to the upper portion of the oblique hole 30a, the sliding pin 36a gets over the distal end portion 32j of the sickle portion 32. As a result, the hook portion 32e of the sickle portion 32 that has been biased in the direction in which the rod-shaped portion 12 is wound is biased in the opening direction, as shown in FIG. Therefore, the main body 2 can be unlocked from the “closed state” to the “open state”.

  Next, a method for maintaining the “closed state” of the main body 2 will be described. As shown in FIG. 18, in the main body 2 in the “closed state”, when the lock shaft 35e of the lock portion 35 is rotated counterclockwise, the rotation portion 35a is rotated counterclockwise around the lock shaft 35e. To turn. Then, the upper and lower parts 35 b connected to the rotating part 35 a move downward along the vertical holes 30 c of the housing 30. As the upper and lower portions 35b move downward, the tip 35d of the upper and lower portions 35b moves to a position where it abuts on the lever head 34g of the lever hub 34, as shown in FIG. The distal end portion 35d abuts on the lever head 34g, thereby preventing the lever hub 34 from rotating. As a result, the “closed state” of the main body 2 can be maintained. That is, the lock | rock of the main-body part 2 and the strike part 3 can be strengthened further.

As described above, according to the present embodiment, both the main body 2 and the strike part 3 can be easily locked together.
Further, according to the present embodiment, for example, even when the ground is uneven and the vertical position of the main body portion 2 and the strike portion 3 is shifted, locking can be easily performed.

  In the above-described embodiment, the main body 2 is attached to the end of the telescopic gate 90 (extensible part), and the strike part 3 is attached to the gate pillar 92 (fixed part), but the present invention is limited to this. Is not to be done. For example, the main body 2 may be attached to the gate pillar 92 (fixed part), and the strike part 3 may be attached to the telescopic gate 90 (expandable part). Alternatively, in a telescopic gate having two telescopic parts, the main body part 2 and the strike part 3 may be attached to each telescopic part and used.
