Abstract

(57) [Summary] [Purpose] To realize a rainproof structure that does not depend on the elasticity of the packing, and improve reliability and maintainability. [Structure] In a rainproof structure of an outdoor housing, a wind and rain penetration preventing metal fitting 3 is attached to a space between the housing body 1 and the housing door 2, and the drainage grate 6 installed inside the housing door 2 passes through the space. The rainwater is discharged to the outside of the housing body 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rainproof structure between an enclosure body and an enclosure door in an outdoor enclosure.

[0002]

[Prior Art]

 Conventionally, a rainproof packing such as neoprene sponge is generally used as a rainproof structure for such an outdoor housing. This will be described with reference to FIGS. 4 and 5.

FIG. 4 and FIG. 5 are a perspective view and a cross-sectional view showing a rainproof structure of an outdoor housing using a rainproof packing. The housing body 10 has an opening, and an outer peripheral frame 17 is provided on the outer circumference of the opening. The housing door 11 is installed so as to close the opening of the housing body 10 with a hinge mounting bracket 12. The rainproof packings 13 to 16 are attached to the inside of the housing door 11 by an adhesive tape or the like (not shown), and when the housing door 11 is closed, the gap between the packing and the outer peripheral frame 17 of the housing body 10 is eliminated. Furthermore, it is configured to be slightly compressed with an appropriate pressure. Therefore, rainwater is prevented from entering the inside of the housing body 10 from between the housing body 10 and the housing door 11.

[0004]

[Problems to be solved by the device]

 In the rainproof structure having the above structure, the rainproof packing is compressed every time it is opened and closed, which causes deformation and cracks, and rainwater may enter the inside of the housing. Therefore, it will be necessary to pay attention to the rain packing because it will be replaced every few years. In addition, a new packing for rainproofing and an additional member were required at the time of replacement, which caused labor and cost problems.

[0005]

[Means for Solving the Problems]

 The present invention is a rainproof structure for an outdoor housing. A metal fitting is installed behind the outer peripheral frame located at the outer periphery of the front opening of the housing body at intervals to prevent wind and rain from entering. Provide so that even the metal fittings are covered. Further, according to another embodiment of the present invention, a drain gutter that enters the inside of the opening is provided inside the housing door along the inside of the outer peripheral frame.

[0006]

[Action]

 With the above configuration, since a space that is parallel and has a narrow gap is provided between the flange portion of the housing door and the wind and rain intrusion prevention metal fitting, the amount of rainwater entering and the intrusion speed can be suppressed. In addition, according to another embodiment of the present invention, the rainwater that has entered is discharged to the outside of the main body of the housing through the drain, so that the rainwater does not enter the main body of the housing.

Further, since there is little contact with the member for the waterproof structure and no load is applied to the member, the member is not damaged.

[0008]

【Example】

 1 and 2 are a perspective view and a sectional view showing an embodiment of the present invention. The housing body 1 has an opening, and is provided with an outer peripheral frame 18 that surrounds the outside of the opening over the entire circumference of the opening. Behind the outer peripheral frame 18, the wind and rain intrusion prevention tool 3 is installed on the housing body 1 at a predetermined interval. The housing door 2 is bent at its four sides inward, and its portion forms a collar 19.

The housing door 2 is attached to the weather-intrusion prevention fitting 3 on either one of the housing body 1. In this case, the housing door 2 is attached by an appropriate means such as a hinge. The collar 19 of the housing door 2 is set to have a length that reaches the rear end portion of the wind and rain intrusion prevention tool 3 in a state where the housing door 2 is closed. Further, a drain grate 6 is installed inside the casing door 2. The drain gutter 6 receives rainwater entering from between the outer peripheral frame 18 and the housing door 2 and drains it. Therefore, the drain gutter 6 is installed with the opening facing the outer peripheral frame 18 on at least three sides of the upper side and both sides. The outer peripheral frame 18 on the bottom surface is provided with an escape portion 22 so as not to interfere with the drain gutter 6 when the housing door 2 is closed.

FIG. 6 is a partially enlarged sectional view showing the drainage structure. The wind and rain intrusion prevention metal member 3 is a member having a U-shaped cross section, and is fixed to the housing body 1 with a predetermined distance from the outer peripheral frame 18. Further, the height of the wind and rain intrusion prevention fitting 3 from the surface of the housing body 1 is substantially equal to that of the outer peripheral frame 18. The direction of the U-shaped opening is opposite to the outer peripheral frame 18 side or 180 degrees. Alternatively, as shown in FIG. 7, the shape may be such that the direction of the opening is directed toward the outer peripheral frame 18 and only the joint portion with the housing body 1 is inverted by 180 degrees. The collar 19 of the housing door 2 has a length that covers the vertical portion of the rear end of the wind and rain intrusion prevention fitting 3. As a result, since the flange 19 and the wind and rain intrusion prevention metal fitting 3 have a parallel portion with a narrow interval, rainwater vigorously and does not intrude in large amounts between the wind and rain intrusion prevention metal fitting 3 and the collar 19. The rainwater that has entered falls into the groove A of the wind and rain intrusion prevention metal fitting 3 and the outer peripheral frame 18, flows along the groove A between them, travels along the left and right side surfaces of the housing body 1 and is discharged to the outside, so it does not enter the inside. .. Rainwater that has entered between the outer peripheral frame 18 and the casing door 2 without falling between the wind and rain intrusion prevention device 3 and the outer casing 18 then penetrates along the casing door 2. The invading rainwater is provided inside the housing door 2 and is received by the drainage troughs 6 projecting inward from the outer peripheral frame 18, guided to the left and right, and transmitted to the outside through the drainage troughs 6 on the left and right. Do not invade.

FIG. 3 is a perspective view showing another embodiment of the present invention. In the rainproof structure of the outdoor casing described with reference to FIG. 1, the drainage gutter 9 is inclined so as to descend from the center toward the rainwater drainage fittings 9 on the left and right to improve drainage efficiency here.

FIG. 8 is a partially enlarged sectional view showing a modified example of the outer peripheral frame 20. The outer peripheral frame 20 has a protrusion 21 projecting toward the drain gutter 6 on the outer peripheral frame 18 described with reference to FIG. Thereby, the rainwater attached to the outer peripheral frame 18 does not flow to the inside of the casing along the casing main body 1 but collects at the lower end of the protruding portion 21 and then drops to the drainage trough 6. Therefore, rainwater that tries to enter along the inside of the casing body 1 is reliably guided to the drainage trough 6.

[0013]

[Effect of the device]

 As described above in detail, according to the present invention, since the structure does not depend on the elasticity of the rainproof packing, it is not necessary to use the conventional rainproof packing as the rainproof structure of the outdoor housing. Therefore, it is possible to prevent water leakage to the inside of the housing due to deterioration of the rainproof packing, and to eliminate the need to replace the rainproof packing, so that it is possible to reduce the replacement labor and the member cost.
