  • Plate for connecting elongated plates
    Patent number: 5553434
    Abstract: The present invention has an arrangement that two ends of a rectangular metal plate are turned up and the two ends are caused to approach at the central portion of the rectangular metal plate while maintaining a small gap so that a flat-pipe-type connection plate is formed, and the ends of elongated metal plates are slightly bent downwards to form insertion members which are inserted into the upper central gap of the connection plate from two directions.The thus-arranged structure causes rain in the connection portion to enter through the gap between the ends of the elongated plates corresponding to the upper central gap of the connection plate. Rain allowed to enter flows downwards through the flat-pipe-like connection plate. Since the lower portion of the connection plate is positioned upper than the lower elongated plate, rain is discharged onto the lower following elongated plate.
