Description

[Detailed description of the invention] The present invention is made by bringing an inner wall contact plate a and an outer wall contact plate a into contact with the inner wall surface and outer wall surface of a wall in which a chimney window hole is formed, and fitting the fitting tubes of both into each other. When it is installed on a wall, this fitting tube is fixed with a fixing device provided inside, so that this product can be easily installed on the wall.Please refer to the attached drawing for its configuration. The details are as follows.

A chimney support hole 1 in the center and a number of ventilation holes 2 around the chimney window hole, which fit into each other, leaving a peripheral flange 3 on the back side of two inner and outer wall panels a and b. Square fitting cylinders 4 and 5 of size 12 are provided protrudingly.

A channel-shaped guide rod 6 is attached to the inside of both walls of this one fitting tube 5 in the fitting direction.

A slide fitting plate 7 which is slidably fitted exactly into the guide rod 6 is attached to the inside of both walls of the other fitting cylinder 4 in the fitting direction with a fitting gap between the wall surface and the guide rod 6.
A fixing device 11 for the slide fitting plate 7 is provided.

The fixing device 11 in the drawings has a shaft 9 mounted on a bearing piece 8 provided at one end of a guide rod 6, and a lever 10 having a locking portion 13 is pivotally mounted on the shaft 9 so as to be able to rise and fall freely. Illustrated.

Since the present invention is constructed as described above, there is a chimney support hole in the center.
, two inner and outer wall panels a and b with many ventilation holes 2 drilled around them, square fittings approximately the size of 12 chimney window holes that fit into each other with a little peripheral flange 3 left on the back side of each. Since the joint pipes 4 and 5 are protruded, an inner wall abutting plate a is attached to the inner wall surface of the wall in which the chimney window hole 12 is formed.
When the outer wall abutting plates are brought into contact with the outer wall surface, the fitting tubes 4 and 5 of the inner wall abutting plate a and the outer wall abutting plate will fit into each other in the chimney support hole 12, and the fitting tube 4 will slide into place. Since the plate 7 is slid into the guide rod 6 of the fitting cylinder 5, the fixing device 11 is operated to fix the slide fitting plate 7 to the guide rod 6.

Therefore, the inner and outer wall contact plates a and b are attached to the inner and outer wall surfaces through the chimney window hole 12.

In this case, the fixing device 11 can be easily operated by inserting your hands through the chimney support holes 1 of the inner and outer wall contact plates a and b.

In this way, the present invention has inner and outer wall contact plates a and b like conventional products.
The fitting tubes 4 and 5 of the inner and outer wall contact plates a and b, which are in close contact with the inner and outer wall surfaces of the chimney window hole 12 formed in the wall instead of being nailed, respectively, are fitted into each other. Fitting tube 4, 5
Since both are fixed, the inner and outer wall abutting plates a and b can be securely attached to the inner and outer wall surfaces.

The final fixation of the fitting tubes 4 and 5 can be achieved reliably by fixing the guide rod 6 and the slide fitting plate 7 at two locations on both sides using the fixing devices 11, and the operation thereof is also easy.

Therefore, even in reinforced concrete houses as well as wooden houses, if there is a chimney window hole, you can easily and reliably install the inner and outer walls a,
It becomes a ventilation window frame that exhibits excellent practicality such as being able to be attached to a wall.

Claims (1)

[Scope of utility model registration request] A chimney window consisting of two rectangular inner and outer wall panels a and b, with a chimney support hole 1 in the center and many ventilation holes 2 around it, that fit into each other with a slight flange 3 left on the back side. Rectangular fitting cylinders 4 and 5 with large holes 12 are provided, and a channel-shaped guide rod 6 is provided in the fitting direction on both walls of one fitting cylinder 5 on the side to be fitted. A slide fitting plate 7 which is exactly slid into the inside of the fitting tube 4 is provided on the inside of both walls of the other fitting tube 4 in the fitting direction with a fitting gap therebetween, and a fixing device 11 for the slide fitting plate 7 is provided on the guide rod 6. The fitting tubes 4 and 5 of the inner and outer wall contact plates a and b are directed inwardly toward each other.
The ventilation window frame is characterized in that the sliding fitting plate 7 is fitted into the guide rod 6 by sliding.
