BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation fan mounting frame for mounting a ventilation fan, a weather cover and the like on a house.

[0002]

2. Description of the Related Art Conventionally, as a ventilation fan mounting frame of this kind, as shown in FIGS. 4 and 5, an outlet 1 is internally provided in an opening of a wall surface of a house or the like (not shown), and a frame body 2 made of wood is mounted. It is known that the shutter 3 and the ventilation fan 4 are fixed to the frame body 2 by a mounting screw 6 made of, for example, a wood screw 5 (see, for example, JP-A-55-3228).

[0003]

Since the conventional ventilation fan mounting frame is constructed as described above, when the shutter 3 and the ventilation fan 4 are mounted on the frame body 2, the shutter 3 and the ventilation fan are determined depending on the mounting position. 4 had to be held in accordance with the mounting position, and there was a problem that workability was poor, such as one person being unable to work.

Further, when the wood screw 5 is used and the frame 2 is made of a soft material, there is a problem that the shutter 3 and the ventilation fan 4 fall because the wood screw 5 does not work.

The present invention has been made to solve the above problems. The shutter and the ventilation fan can be easily and safely attached to the frame, and the frame is made of a soft material. The purpose is to obtain a ventilation fan mounting frame that can secure sufficient mounting strength.

[0006]

A ventilation fan mounting frame according to the present invention is provided with an opening provided in a wall surface of a house or the like, a frame body mounted in the opening, and a frame member mounted to the frame body through a screw member. And a plate having a screw hole in which the screw member is screwed is embedded in the frame body,
A screw member passage hole communicating with this screw hole is provided.

[0007]

In the present invention, the frame body is provided with an opening provided on the wall surface of a house or the like, a frame body mounted on the opening body, and a ventilation fan mounted on the frame body through a screw member. By embedding a plate in which a screw hole into which the screw member is screwed is bored and providing a screw member passage hole communicating with the screw hole, the screw member can be inserted into the screw member passage hole. The screw member is screwed into the screw hole of the plate.

1 to 3 are views showing an embodiment of the present invention, in which 10 is a ventilating fan, an electric motor 12 having propeller blades 11 and mounting feet projecting from the electric motor 12 in all directions. 13 and a mounting flange 15 having a mounting hole 14 at the tip thereof. Reference numeral 16 is a wall of a house 17 or the like, 18 is an opening formed in the wall 16, 19 is a frame body attached to the opening 18, and is made of wood, for example, and a plurality of frame pieces 20 are combined as shown in FIG. It will be done. Reference numeral 21 denotes a plate, which is made of a steel plate and has a screw groove 22 in the center and a screw hole 23.
Is provided and is embedded in the frame piece 20. Reference numeral 24 denotes a screw member passage hole, which communicates with the screw hole 23 of the plate 21 from the surface of the frame piece 20. Reference numeral 25 is a screw member, for example, a through bolt. A weather cover 26 is mounted on the outdoor side of the house 17, and has a mounting portion 27 having a mounting hole (not shown) at the peripheral edge.

In the ventilation fan mounting frame constructed as described above, as shown in FIG. 3, the frame body 19 is provided in the opening 18 of the wall 16.
And attach the mounting flange 1 of the ventilation fan 10 to the frame body 19.
5 is abutted and the screw member 25 is inserted into the screw member passage hole 24 through the mounting hole 14. Next, by rotating the screw member 25 with a tool (not shown), the screw member 25 is screwed into the screw hole 23 of the plate 21, and the ventilation fan 10 is fixed to the frame body 19. Furthermore, the weather cover 2 is used in the same manner.
6 is fixed to the outdoor side of the frame body 19. Since the plate 21 is embedded in the frame body 19 and the screw member passage holes 24 communicating with the frame body 19 are provided in this manner, positioning of the ventilation fan 10 and the weather cover 26 at the time of mounting can be facilitated, and further the frame body Even if 19 is a soft material, the plate 21 can secure the mounting strength.

Although the plate 21 is embedded in the frame piece 20 in the above embodiment, the same effect as that of the above embodiment can be obtained with a general nut (not shown).

[0011]

As described above, the present invention is provided with the opening provided on the wall surface of the house, the frame body attached to the opening, and the ventilation fan attached to the frame body through the screw member. The plate having a screw hole into which the screw member is screwed is embedded in the frame body, and a screw member passage hole communicating with the screw hole is provided, so that the ventilation fan can be attached to the frame body. The screw member passage hole and plate can be used easily and safely, and the mounting can be secured for a longer period of time.
