Abstract:
PURPOSE: To prevent a drop bar from rising, when the door body of a gate is closed at a stop position, and adjust the height of the drop bar at a fine pitch.
CONSTITUTION: The surface of a gate door body 3 coming to be faced to another gate door body 4 in closed state is provided with an opening 20a, and a box body 20 with projections 20c of rectangular longitudinal cross section at the predetermined vertical intervals is laid behind the rear side 20b. Also, the top of a drop bar 21 laid so as to pass through the bottom 20f of the box body 20 for extension therein is provided with a slide block 23 of rectangular longitudinal cross section having height at the side of the rear side 20b of the box body 20 smaller than the height of a recess 20h between upper and lower projections 20c and 20c on the side 20b. In this case, the block 23 is laid, so as to be freely slidable in parallel to a direction from the rear side 20b of the box body 20 to the opening 20. Furthermore, a spring 24 is housed in a horizontal aperture formed in the slide block 23 for the energization thereof toward the rear side 20b of the box body 20.
