DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilating device provided on a square wave plate.

[0002]

2. Description of the Related Art In general, a square wave plate is often used for applications such as a back plate provided on the back side of a garage. However, since the square corrugated plate is formed with a plurality of parallel rectangular corrugated recesses at regular intervals, when it is necessary to provide a ventilating device on this square corrugated plate, the square corrugated plate has ventilation holes. Open
A ventilator is attached to the vent, but when the vent includes a recess, rainwater easily penetrates from the recess in this portion. As a countermeasure, a convex portion corresponding to the concave portion may be integrally formed in advance in a portion that comes into contact with the periphery of the ventilation opening of the ventilator.

[0003] However, even in this case, dimensional errors in processing or forming the concave and convex portions are unavoidable, and there is a possibility that rainwater may enter between the concave and convex portions.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks, and in particular, to provide a ventilator capable of effectively preventing rainwater from infiltrating in close contact with a concave portion of a square wave plate.

[0005]

Means for Achieving the Object In order to achieve the above object, a ventilating apparatus according to the present invention is characterized in that a square wave plate having a plurality of parallel angular wave-shaped recesses formed at regular intervals has at least one sheet. An opening is formed so as to cover the recess, a ventilation body is attached to the opening, and the following requirements are provided. (A) The ventilation body has a ventilation opening / closing mechanism and a ventilation main body having an outer edge abutting on a peripheral edge excluding a concave portion of the opening, and a fixing tool fixed to the ventilation main body with a square wave plate sandwiched therebetween. (B) In a portion corresponding to the concave portion of the outer edge portion, a concave block for fitting into the concave portion is press-fitted to the outer peripheral portion of the ventilation main body.

[0006]

In the above configuration, when assembling the ventilation device, the recess block is inserted into the insertion space at the outer edge of the ventilation main body with a margin into the outer edge of the ventilation main body. To one of the corrugated sheets, and firmly tighten and fix the corrugated sheet between them.

As described above, when the fixing tool is pressed against the rectangular corrugated sheet by screwing, the pressing block simultaneously presses the concave block into the concave section of the rectangular corrugated sheet in the direction opposite to the fitting direction. Although it is deeply press-fitted, the degree of press-fitting varies depending on the size of the concave block and the concave portion of the square wave plate, so that the concave block fits exactly in the concave portion. Therefore, infiltration of rainwater can be effectively prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 denotes a square wave plate. This square corrugated plate 1 is a metal plate material such as iron, aluminum or the like in which a plurality of parallel rectangular corrugated concave portions 2 are formed at regular intervals.
In this plate material, a ventilation opening 3 is formed.
Is provided with a ventilation device 4 made of synthetic resin. The opening 3 includes two recesses 2.

As shown in FIG. 3, the ventilation device 4 includes a ventilation body 6 having a plurality of ventilation ports 5 at regular intervals,
A fixture 7 is fastened and fixed to the ventilation main body 6 with the square wave plate 1 interposed therebetween.

As shown in FIG. 4, the ventilation main body 6 is provided with an opening / closing mechanism in which an opening / closing plate 8 is slidably disposed behind the ventilation opening 5. The opening / closing plate 8 is also provided with ventilation holes 5 a at the same interval corresponding to the ventilation holes 5. An operation knob 9 is integrally formed below the opening / closing plate 8 and protrudes to the front side from an opening 10 formed at a lower portion of the ventilation main body 6. Thus, the ventilation opening 5 is opened and closed by moving the operation knob 9 left and right.

The ventilation main body 6 has an outer edge 11 abutting on the periphery of the opening 3 except for the concave portion 2 and a fitting edge 12 large enough to be fitted into the opening 3.
The outer edge 11 is formed larger than the opening 3 and
The contact surface is formed flush. In addition, the outer edge 11
An insertion space 13 is formed on the back side of the device, and two positioning and reinforcing pieces 14 are formed in the insertion space 13. A notch 15 and an engagement groove 16 are formed at the left and right positions on the upper and lower portions of the fitting edge 12. A screw receiving portion 17 is formed at a position on the rear side of the ventilation main body 6 corresponding to the upper and lower cutouts 15. The screw receiving portion 17 passes through the long hole 18 of the opening / closing plate 8 and faces the back side of the ventilation main body 6. The engaging groove 16 and the positioning and reinforcing piece 14 are formed at corresponding positions.

Further, a recess block 19 is arranged at a position corresponding to the recess 2 on the outer edge portion 11. The concave block 19 has an L-shaped piece 20 on the upper bottom side of a trapezoidal block main body 19a having a size that fits into the concave portion 2.
In the lower bottom part, three nail pieces 21 are formed, respectively.
Locking jaws 22 are formed at the ends of the adjacent claw pieces 21 on opposite sides of each other, and a groove 23 is formed between the claw pieces 21.

The fixture 7 is provided with a screw receiving portion 17 of the ventilation body 6.
And a fitting piece 25 sized to fit into the notch 15, and a pressing piece 26 having a substantially L-shaped cross section is formed above and below the fitting piece 25.

In the above construction, when assembling the ventilator, the claw pieces 21 of the concave block 19 are inserted into the insertion space 13 of the outer edge portion 11 of the ventilation main body 6 as shown in FIGS. The L-shaped piece 20 is engaged with the engaging groove 16 of the fitting edge 12 while the positioning and reinforcing piece 14 is inserted so as to be inserted into 23. Since the locking jaws 22 are formed above and below the claw pieces 21, the claw pieces 21 are pressed into the insertion space 13 by a wedge effect. The press-fitting of the claw pieces 21 is performed in such a manner that the concave block main body 19a does not abut on the contact surface of the outer edge portion 11 with the square corrugated plate 1, that is, as shown in FIG.

In this state, the fitting edge 12 of the ventilation main body 6 is fitted into the opening 3 of the square corrugated plate 1 as shown in FIG. Then, the fitting piece 25 of the fixture 7 is fitted into the notch 15 of the ventilation main body 6 from the back side of the square corrugated plate 1, and further, a fastening screw 27 is inserted from the screw hole 24 to insert the screw receiving portion 17 of the ventilation main body 6. And the pressing piece 26 of the fixture 7 and the outer edge 11 of the ventilation body 6
Thus, the square wave plate 1 is strongly tightened and fixed.

As described above, when the fastening screw 27 is tightened, the pressing piece 26 of the fixing tool 7 presses the rectangular wave plate 1 against the outer edge portion 11 to press the rectangular wave plate 1 against the outer edge portion 11. Block 19 for recess that has entered recess 2
Is also pressed in the direction opposite to the fitting direction of the ventilation main body 6, and the claw pieces 21 are further pressed into the insertion space 13 deeply.
Will differ depending on the size of the concave portion 2. However, the upper bottom portion of the block for concave portion 19 and the end faces on both sides thereof fit exactly in the concave portion 2. Therefore, infiltration of rainwater can be effectively prevented.

Further, since the pressing piece 26 is formed in an L-shaped cross-section and has elasticity, the pressing piece 26 elastically presses the square wave plate 1, so that vibration and external force can be absorbed and breakage can be effectively prevented.
