Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail cover opening / closing device for an openable / closable roof capable of opening / closing a part of the roof depending on the weather.

[0002]

2. Description of the Related Art In recent years, an all-weather stadium in which the entire stadium is covered with a roof has attracted attention as a stadium that can compete without being affected by rain or the like. In addition, as an all-weather stadium of this kind, it has been proposed to adopt an openable roof in which part of the roof can be opened and closed depending on the weather. In a stadium with such a retractable roof, it is effective for energy saving because it can be used for daylighting and ventilation by opening part of the roof during sunny weather, but it is constructed in a region with a lot of snow. In such a case, there is a problem that snow accumulates on the guide rails that move the movable roof that opens and closes, which becomes an obstacle when opening and closing the movable roof.

In order to solve such a problem, for example, Japanese Patent Laid-Open No. 63-308168 (Japanese Patent Publication No. 4-51622) and Japanese Utility Model Laid-Open No. 4-56808 disclose a snow removing device for preventing snow from accumulating on the guide rail. Also, a sealing structure for sealing both ends of the moving roof has been proposed. In the snow removal device of the former publication, a rail housing and a rail cover are provided so as to cover a guide rail on which a traveling carriage supporting an openable / closable roof member travels, and the tip of the rail cover is brought into contact with or separated from the rail housing. In addition to pivotally supporting the base end so that it can be opened and closed in the direction, a wedge-shaped plow is provided on the side of the traveling carriage to open the rail cover as the traveling carriage travels. In addition to preventing snow accumulation, when the roof member is opened and closed, the plows provided on the traveling carriage open the rail cover, so that traveling of the traveling carriage is not hindered.

In the seal structure of the latter publication, a seal groove is provided so as to be parallel to the rail grooves for supporting both ends of the moving roof, the sealing water is stored in the sealing groove, and the sealing structure is attached to both ends of the moving roof. By immersing the lower end of the sealing plate in the sealing water in the sealing groove, both ends of the moving roof are sealed.

[0005]

However, in the snow removal device of the former publication, although it is preferable that one rail is covered with the rail housing and the rail cover, the rail mounting plate fixing the rail is also covered at the same time, If there is another rail in the direction orthogonal to the rail, the rail housing and rail cover will be large, and a large force will be required to open and close the rail cover. There is a defect. In addition, when snow is accumulated above the height of the rail housing or the rail cover, when the rail cover is opened, surrounding snow falls on the rail and the roof member cannot be moved.

On the other hand, in the seal structure of the latter publication, when the rail groove has an arch shape, even if the seal groove is provided along the rail groove, it is difficult to seal because the seal water cannot be stored in the seal groove. Even if this seal structure is adopted for the rail groove of, the seal water may freeze during the snow season.If the seal water freezes, it may be difficult to open or close the moving roof, or if it is opened or closed by force, There is a problem such as damage to the seal plate. The present invention has been made in order to improve the conventional problems, and an object of the present invention is to provide a rail cover opening / closing device for a retractable roof capable of reliably preventing snow accumulation on a guide rail on which a movable roof travels. It is a thing.

[0007]

In order to achieve the above object, the present invention relates to an open / close type roof having a movable roof part of which can be opened / closed, and a guide on which the movable roof runs when the movable roof is opened / closed. A rail cover is provided above the rail so as to be openable and closable in a direction orthogonal to the guide rail by an opening / closing means. Further, the opening and closing means is provided on the movable roof side, and an opening cam that sequentially opens each rail cover when the movable roof is opened, an actuator that closes the opened rail cover, or a wire is connected to each rail cover, In addition, the opened rail cover is configured by a weight that closes by its own weight. Further, the rail cover is opened by the opening cam provided on the movable roof side together with the opening of the movable roof, and is closed by the weight of the rail cover.

[0008]

[Operation] With the above configuration, since the upper part of the guide rail is covered by the rail cover when the movable roof is closed, snow does not accumulate on the guide rail and each rail cover opens and closes in the direction orthogonal to the guide rail. It can be opened and closed smoothly. Also, when the movable roof is opened, the rail cover opened by the opening cam provided on the movable roof side is closed by the actuator, so that the rail cover can be opened and closed surely and the rail cover can be closed. By using the dead weight of the weight and the rail cover, the drive source is not required, which is economical.
