DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for maintaining a good indoor air condition by introducing necessary air by mounting it on a wall or a sash and replacing it with contaminated air in the room, or partitioning a room or door. The present invention relates to a ventilator for ventilation of a corridor or an adjacent room by being attached to a vehicle.

[0002]

2. Description of the Related Art Conventionally, so-called slide-type ventilators for exchanging indoor air and outdoor air have been provided. Specifically, for example, a fixing plate having a small hole formed therein is disposed on a part of the window, and a slide plate having the same small hole formed thereon is disposed so as to overlap the small hole fixing plate. The opening / closing operation of the through-hole communicating with the outside is performed by the sliding operation. Further, when such a device is not provided, a ventilation glass sliding door is disposed above the window with a horizontal rail interposed therebetween, and the glass sliding door is formed with a slight open gap formed therebetween. There is also an auxiliary lock that can lock the sliding door to provide ventilation.

[0003]

However, in the case of the above-mentioned slide type ventilator, the friction between the small hole fixing plate and the slide plate is large. It will be labor intensive.
Further, even when a small-sized slide plate is used, there is a problem that dust or the like intervenes between the two plate members with time, and the slide operation gradually becomes less smooth. Also, it is difficult to completely seal the seal between the fixed plate and the slide plate, and especially in the winter, outside cold air flows in,
There are also problems such as causing a cold draft.

Therefore, a main problem of the present invention is that even if a ventilation device is provided over the entire width of a sash or in a laterally long length in a horizontal window, opening and closing operations can be performed smoothly, and Another object of the present invention is to provide a ventilation device capable of maintaining a smooth opening / closing operation for a long period of time without being affected by dust and the like, and of ensuring airtightness inside and outside the room.

[0005]

According to a first aspect of the present invention, there is provided a casing having a ventilation opening on each of an outdoor side surface and an indoor side surface, and an upper end side edge or a lower end side edge inside the casing. An opening / closing flap that is swingably disposed as a center of rotation and communicates or closes a passage from the outdoor ventilation port to the indoor ventilation port, and an opening / closing operation unit for swinging the opening / closing flap. And
The opening / closing operation unit includes a case, an operation switch attached to the case and held swingably, and a shaft portion penetrated and held by the operation switch, and the opening / closing operation unit is eccentric from a position where the shaft portion is provided. An operating member having an engaging rod engaged with the opening / closing flap; and an angle regulating holding member for holding the operating member at a predetermined rotation angle, wherein the operating member is pivoted by a swing operation of the operation switch. The opening / closing flap that rotates around and engages with the engaging rod is operated to swing.

According to a second aspect of the present invention, a vent hole is provided on each of the outdoor side surface and the indoor side surface, and an insertion engagement portion or a glass fitting groove for a member to be mounted is formed at an upper end and a lower end in an arbitrary combination. Casing,
An opening / closing flap which is arranged inside the casing so as to be swingable about an upper end side edge or a lower end side edge and which communicates with or closes a passage from the outdoor vent to the indoor vent; and the open / close flap. A gasket member for ensuring airtightness by abutting the tip of the opening / closing flap when closing the opening / closing flap, and an opening / closing operation section for swinging the opening / closing flap, wherein the opening / closing operation section includes a case,
An operation switch attached to the case and held in a swingable manner, and an engaging rod engaged with the opening / closing flap at a position eccentric from a position where the shaft is disposed while the operation switch has a shaft penetrating therethrough. And an angle regulating holding member that holds the operating member in a predetermined rotation angle state, and the operating member rotates around a shaft portion by a swing operation of the operation switch, and is rotated by the engaging rod. The open / close flap which is engaged is operated to swing. In this case, the tip of the gasket member is branched in a Y-shape, and the air-tightness can be reliably maintained by bringing the tip of the opening / closing flap into contact with each of these Y-shaped branched tongue pieces. become.

In the present invention, since the swingable opening / closing flap is used as an operating member for communicating or closing the ventilation opening, the opening / closing flap is extended over the entire width of the sash or in the horizontal direction at the horizontal connecting window. Even if the ventilation device is arranged in a length, the opening and closing operation can be performed smoothly without any force. In addition, since the gasket member that comes into contact with the opening / closing flap is provided, airtightness between the inside and outside can be reliably ensured by the abutting relationship between the two.

The structure of the opening / closing operation section includes a case, an operation switch attached to the case and held in a swingable manner, and a shaft portion penetrated and held by the operation switch. An actuating member having an engaging rod engaged with the opening / closing flap at a position eccentric from the part, and the operating member is rotated around a shaft portion by a predetermined swing operation to engage the engaging rod. When the open / close flap is configured to swing, the swing of the open / close flap can be easily controlled between a closed position and an open position.

On the other hand, regarding the configuration of each part in the ventilating apparatus, first, regarding the mounting mode of the opening / closing flap,
A C-shaped annular member is provided integrally from the inner wall surface inside the casing, while a hinge portion fitted to the C-shaped annular member is provided on a side edge of the opening / closing flap, and the hinge portion is used as a center of rotation. It is preferable that the opening / closing flap is swingably supported. By adopting this configuration, the initial purpose can be reliably achieved with a small number of parts.

[0010] Further, for example, in a situation where the operation portion cannot be directly operated due to a high mounting position of the ventilation device, an operation rod is provided in the opening / closing operation section instead of the operation switch. The operating member is caused to swing around the shaft portion by a rotation operation around the axis of the shaft, or two operation cords are provided in place of the operation switches, and the operation member is pivoted by pulling the operation cord. This can be dealt with by swinging around the part.

In the ventilating apparatus, it is preferable that an insect repelling net is stretched over at least one of the ventilation holes on the outside and inside surfaces.
