It is a horizontal sectional view in the joint part of both doors. It is a vertical sectional view of the right door. It is a horizontal sectional view in the fitting part of the conventional both doors.

  Preferred embodiments of the present invention are shown below. In the present specification, the top, bottom, left, and right and front and rear directions indicate the directions shown in FIG. 1, and in the present embodiment, one door is the left door 2a and the other door is the right door 2b. In FIG. 1, 1 is a housing body, and 2 is a double door with a left door 2a and a right door 2b. Both doors 2 are closed by superimposing the left end portion of the right door 2b, which is closed later, from the outside on the right end portion of the left door 2a, which is closed first by the vertical rotation shaft. In addition, the draining part 3 as shown in FIG. 2 is formed in the periphery of the opening part of the housing | casing main body 1 like the past. As shown in FIG. 3, the draining portion 3 is provided with a left packing 4a provided in a substantially U shape on the inner peripheral edge of the left door 2a, and a substantially square shape on the inner peripheral edge of the right door 2b. The right packing 4b is in contact with each other, thereby preventing water from entering the housing body 1. Further, as shown in FIG. 1, the left door 2a is provided with a handle 5 for moving up and down a locking bar (not shown) locked to the back surface of the draining portion 3, and the right door 2b is formed on the left door 2a. A clamp-type handle 6 that sandwiches a not-shown locking piece is provided. The doors 2 are closed and locked by operating the handles 5 and 6.

  As shown in FIG. 4, at the right end of the left door 2a, there is formed a recessed portion 7 having a substantially U-shaped horizontal section that extends in the vertical direction of the casing and is recessed in the depth direction (backward) of the casing. The draining metal fittings 10 each having a substantially U-shaped vertical section are welded to the upper and lower ends of the recessed portion 7. By providing the recessed portion 7 and the draining metal fitting 10 as described above, even if water enters from above the mating portion where the two doors 2 overlap, water drops can be formed in the order of the upper draining metal fitting 10, the recessed portion 7, and the lower draining metal fitting 10. It is assumed that water can be prevented from entering the housing body 1.

  As shown in FIG. 5, the draining metal fitting 10 provided on the upper part includes a horizontal piece 11, a vertical piece 12 extending vertically downward from the front end of the horizontal piece 11, and a lower piece 13 welded to the recessed portion 7. It is comprised by. The lower piece 13 is formed so as to be inclined rearward of the housing in accordance with the shape of the recessed portion 7.

  Here, as shown in FIGS. 5 and 6, the left packing 4 a provided on the inner peripheral edge of the left door 2 a is protruded from the vertical piece 12 of the draining metal fitting 10 toward the right direction, that is, toward the right door 2 b. The protrusion 20 is provided. The protrusion 20 has a door-side surface that is inclined toward the inside of the housing as it is advanced. In this embodiment, the protrusion 20 is substantially the same as the gap 40 described with reference to FIG. 9 as a conventional problem. The shape, that is, the horizontal cross section is formed to be substantially triangular. By forming such a protruding portion 20 on the left packing 4a, the gap 40 generated by the conventional draining metal fitting 10 abutting on the right packing 4b provided on the right door 2b is completely formed as shown in FIG. Therefore, it is possible to reliably prevent water from entering the housing body 1 from the joint portion of the doors 2.

  In the present embodiment, the shape of the protruding portion 20 is substantially triangular in horizontal cross section, but is not limited to this, and when the both doors 2 are closed, the drainage fitting 10 is provided on the right door 2b. Any shape that can fill the gap 40 generated by contacting the packing 4b may be used.

  Further, as shown in FIGS. 5 and 6, the protruding portion 20 is formed to be curved toward the housing body 1 side. Since the packing 4 is often affixed to both doors 2 by a human hand, the affixing position may vary. Therefore, as shown in the present embodiment, the protruding portion 20 is slightly curved toward the housing body 1 so that the protruding portion 20 is in close contact with the draining portion 3 of the housing body 1 when the left door 2a is closed. Thus, the influence of the variation in the pasting position of the packing 4 can be reduced. Note that, by slightly curving the protruding portion 20, a gap as shown in FIG. 6 is generated between the vertical piece 12 of the draining metal fitting 10 and the standing side 20a of the protruding portion 20 on the draining metal fitting 10 side. 20 is brought into contact with the draining portion 3 and biased forward so that the gap is eliminated, and the standing side 20a is in close contact with the end of the vertical piece 12 as shown in FIG. Can do. At this time, by making the length of the standing side 20a in the depth direction substantially the same as the thickness of the vertical piece 12, both can be brought into close contact with each other and water can be prevented more reliably.

  As shown in FIG. 8, the right packing 4 b provided on the right door 2 b has an extended portion 30 with its end portion extended upward, and the extended piece 30 is a vertical piece formed on the draining metal fitting 10. 12 is preferably covered. Thereby, since the extended part 300 covers the upper part of the gap 40, the waterproof performance can be further improved, and the intrusion of water into the housing body 1 from the joint part of the two doors 2 can be prevented more reliably. It is supposed to be possible.
