Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to a louver used in an opening in an outer wall of a wall-penetrating air conditioner used for air conditioning in buildings, etc.

Prior Art Conventionally, this type of louver has a frame material 42 in which a plurality of blades 41 are embedded, as shown in FIGS. 3 and 4.
A sleeve 44 embedded in an outer wall 43 of a building etc.
It is fixed to the raised part 45 provided around the entire opening of the building with screws 46 and waterproof washers 47, so that rainwater can be
The attachment part of the screw 46 of the sleeve 44 and the frame member 4 should be prevented from penetrating into the joint part 48 between the sleeve 44 and the sleeve 44.
The joint between 2 and the outer wall 43 was caulked with a sealant 49.

Problems to be Solved by the Invention In such a conventional configuration, since the louver normally weighs 5 to 10 kg, it is difficult to align it with the sleeve 44 when fixing it with the screw 46 from the outdoor side of the building's outer wall 43. , the work cannot be done by one person, and as shown in FIG.
Even if the sealing material 49 is caulked between the sleeve 44 and the screwed part of the sleeve 44, the sleeve 4
Since the contact surfaces between the rising part 45 of No. 4 and the frame material 42 are made of the same hard metal, a gap 50 inevitably occurs, and rainwater enters from this gap and seeps into the joint 48 between the sleeve 44 and the outer wall 43. The points were also hot.

The present invention takes these problems into consideration and aims to provide a louver that is easy to install, including caulking, and has a good rainwater prevention effect.

Means for Solving the Problems In order to solve the problems, the present invention has a plurality of blades fixed to the frame material forming the four sides, and a plurality of blades are formed on the frame material on the side in contact with the sleeve to be fixed to the sleeve. A screw hole, a protrusion that protrudes inward from the sleeve to fit into the sleeve, a groove is formed between the protrusion and the sleeve, a sealing material is caulked into the groove, and the screw hole is also fitted into the sleeve. The structure is covered with a sealant.

Effect With this configuration, during installation work, the protruding part of the frame material is fitted into the outer opening of the sleeve fixed to the outer wall, the positional shift of the frame material is regulated, and the protruding part is inserted into the joint between the sleeve and the frame material. The seal material in the grooves also covers the screw holes, so
Prevents rainwater from entering through the screw holes.

Embodiment An embodiment of the present invention will be described based on FIGS. 1 and 2. FIG. 1 is a cross-sectional view of a sleeve and a louver, in which a plurality of blades 1 are fixed to a frame member 2 forming four sides, and this frame member 2 includes a sleeve housing an air conditioner (not shown). A screw hole 4 formed on the side in contact with the sleeve 3 for fixing it to the sleeve 3.
(FIG. 2), a protrusion 6 is provided that protrudes inward of the sleeve 3 in order to fit into the opening 5 of the sleeve 3.

FIG. 2 shows a perspective view of the louver 7, and will be explained based on FIGS. 1 and 2. The opening 5 of the sleeve 3 embedded and fixed in the outer wall 8 of the building
In contrast, the louver 7 with the above configuration is fixed,
For this fixation, a protrusion 6 provided on the frame member 2 is inserted, and is regulated and positioned on the inner periphery of the opening 5 of the sleeve 3. Next, in order to prevent rainwater from entering through the screw holes 4, a waterproof washer 9 is used and the sleeve 3 is fixed to the sleeve 3 using screws 10. Between the outer wall 8 and the frame material 2 of the louver 7 and the sleeve 3
Caulk the screw-fastening portion with sealant 11.

According to this installation, the outer periphery of the protrusion 6 serves as a position restriction for the opening 5 of the sleeve 3, and when installed, a groove 12 is formed on all sides between the sleeve 3 and the sealing material 1.
By configuring the groove portion 12, the caulking work according to No. 1 is simplified because the sealing material 11 does not protrude, and rainwater that enters through the screw hole 4 can also be blocked by the sealing material 14, thereby preventing rainwater from entering. It becomes possible.

Effects of the Invention As is clear from the description of the above embodiments, the louver of the present invention has a structure in which the sleeve and the louver are attached, and a protrusion that fits into the opening of the sleeve is provided on the inside of the louver. The positioning of the louver becomes easy and one person can do the installation work. Further, since a groove for caulking the sealing material is formed by the sleeve and the protrusion, the caulking work is simplified, and the gap where rainwater can enter from the screw hole that fixes the sleeve can be eliminated.
