Description

  The present invention relates to a door-to-door cabinet equipped with two doors suitable for use as an electrical / electronic equipment storage box for outdoor use.

  The door-door cabinet installed outdoors is formed by bending a vertical draining part with a U-shaped horizontal section at the joint of the door (inner door) that is closed first, and the other door is closed when the door is closed. The insertion portion provided on the door (outer door) is inserted into the U-shaped draining portion to prevent rainwater from entering the cabinet. Moreover, an inner side bending piece is formed in the upper edge of each door, and rain water is made to flow down to the U-shaped groove formed in the upper edge part of the cabinet main body. Thereby, rainwater flowing in the back direction of the door can be treated, but rainwater flowing in the joint direction of the door may flow down between the two doors and enter the cabinet.

  Therefore, as shown in FIG. 3 of Patent Document 1, a draining member bent in a U-shape is welded to the upper edge of the door that is closed first, and the tip of the door that is closed later covers the top. In this way, there is one that closes the gap formed at the joint portion of the door.

  However, in this case, as shown in FIG. 12, the upper piece 10 of the draining member 9 is slightly lower than the height of the inner bent piece 4, so that rainwater enters the upper surface of the upper piece 10 of the draining member 9. 12, rainwater flowing in the direction indicated by arrow A enters the inside of the cabinet through the vertical end 13 of the vertical piece 11.

  Therefore, a packing that contacts the upper edge of the cabinet body is provided in the upper part of each door in the horizontal direction to seal between the draining member and the cabinet body.

  However, as shown in FIGS. 10 and 11, there is a level difference between the draining member 9 and the door 2 to be closed first by the thickness h of the vertical piece 11 of the draining member 9. A very small gap 14a between the door 2 and the door 2 is formed on a straight line in the vertical direction at both end points 11a of the intersection of the upper piece 10 and the vertical piece 11, and rainwater may enter the inside of the cabinet body 1 from the gap 14a. was there. Further, as shown in FIG. 11, the packing 7 attached to the back surface of the door 3 to be closed later is compressed by the vertical piece 11 of the draining member 9, and the packing 7 and the close contact portion 6 of the cabinet body 1 are connected. A very small gap 14b is generated on the straight line in the vertical direction at both end points 11a of the line of intersection of the upper piece 10 and the vertical piece 11, and rainwater may enter the inside of the cabinet body 1 from the gap 14b. there were.

  Accordingly, there has been a demand for the development of a door-door cabinet that can reduce the intrusion of rainwater.
