Was. To prevent breakage of the blocking bar, for example, as disclosed in Japanese Patent Application Laid-Open No. H11-5536, the connecting portion between the opening / closing arm and the blocking bar is made a free joint, and a support tool having a brace is attached to the opening / closing arm. Around the root of the arm with a hanging member suspended from the arm
When a vehicle collides with a blocking bar, the blocking bar moves laterally and upward in the direction of travel of the vehicle, reducing the impact on the vehicle, the blocking bar, and the opening / closing arm. Once bent, it bounces back and comes back, so when the following vehicle comes in, the blocking bar that comes back hits violently against the following vehicle, causing a problem that the impact becomes even greater. Therefore, the present invention provides a blocking device that can bend the blocking bar in the vehicle traveling direction when the vehicle collides with the closed blocking bar in the traffic stop instruction state, and prevent the blocking bar from rebounding when the colliding vehicle passes through. The purpose is to obtain.

The rod is turned upward by about 90 degrees to be in the open position so that the vehicle can pass. When a stop instruction signal is received, the drive unit is driven to rotate the open / close shaft in the closing direction, and the blocking rod is turned downward by about 90 degrees. When the vehicle is stopped horizontally by a slight impact on the stop rod with an impact that does not damage the vehicle during this stop instruction state The force applied to the central portion of the blocking bar is less than a certain force, and the bent arm stopper that holds the V-shaped notch of the bending arm with a predetermined force keeps the pressing state, and the blocking bar is closed. Position, but the vehicle collides strongly with the bar with more than a certain force. In this case, the pressing of the bent arm stopper against the V-shaped notch is released, and the blocking bar is bent about 90 degrees in the traveling direction of the vehicle around the bending axis together with the bending arm, and when the vehicle comes into contact with the blocking bar. Less damage.

[0006] Also, the present invention relates to a V-shaped notch which rotates together with the bending arm when the bending arm is rotated about 90 degrees behind the upper surface of the opening / closing arm corresponding to the bending axis (opposite to the traveling direction of the vehicle). If the rebound prevention hook for stopping is provided, the vehicle strongly collides, and when the blocking bar is bent about 90 degrees in the traveling direction of the vehicle about the bending axis with the bending arm, the V-shaped notch of the bending arm is also about 90 degrees. Because it rotates every time, it locks with the rebound prevention hook and keeps the bent state of the blocking bar, preventing the blocking bar from rebounding to the original unfolded closed position, so that it can be The danger caused by the rebound of the blocking bar can be prevented. A blocking device is provided which ensures safety when a vehicle collides with a closed blocking bar in a traffic stop instruction state.

Further, a blocking bar lock shaft is projected from the horizontal upper surface of the bending arm, and a blocking bar lock lever is axially mounted on the blocking bar lock shaft via a blocking bar lock cam, and the blocking bar lock lever is connected to the bending arm. When set in the direction parallel to the above, the blocking bar lock cam presses the blocking bar against the bent L-shaped upright surface of the arm to lock it, and when the blocking bar lock lever is returned to the direction perpendicular to the bent arm, the blocking bar locks. If the bar lock cam is unlocked without pushing the blocking bar, the blocking bar can be easily attached and detached.
