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 system for an openable / closable roof in which a part of the roof can be partially opened / closed according to the weather.

[0002]

2. Description of the Related Art In recent years, all-weather stadiums have been attracting attention, and large open-closed roof-type buildings have been built, such as the Fukuoka Dome, where part of the roof can be opened and closed. As the opening / closing system, a truck that supports the opening / closing roof runs on a rail installed in the roof structure to open / close. In such a stadium with an open / closed roof, it is possible to open part of the roof during sunny days for daylighting and ventilation, which is a very effective way to save energy. In the case of the construction, the snow on the roof is processed by snow sliding, but if the above-mentioned rail portion is exposed to the outside, the snow adheres to the rail, which hinders the opening and closing of the roof and the snow sliding.

Therefore, in order to solve the above-mentioned obstacle, for example, a snow removing device for preventing snow from being accumulated on a rail according to Japanese Patent Publication No. 4-51622, and both ends of a moving roof according to Japanese Utility Model Laid-Open No. 4-56808 are sealed. A seal structure is disclosed. As for the outline of the snow removal device, a rail housing and a rail cover are provided to cover a guide rail equipped with a heater on which a traveling carriage supporting an openable and closable roof member travels, and the rail cover has a tip end of the rail housing. The base end portion is rotatably supported so that it can be opened and closed in the contacting / separating direction, and a wedge-shaped plow that opens the rail cover as the traveling vehicle travels is provided on the traveling vehicle side. . The rail housing and the rail cover prevent snow from being accumulated on the guide rail. Further, when the roof member is opened and closed, a plow provided on the traveling carriage opens the rail cover. Therefore, it does not hinder the traveling of the traveling vehicle.

Further, in the above-mentioned sealing structure, seal grooves are provided in parallel with the rail grooves for supporting both ends of the moving roof, the sealing water is stored in the sealing grooves, and the seals provided at both ends of the moving roof. The lower end of the plate is immersed in the sealing water in the sealing groove. In this way, a mechanism is provided to seal both ends of the moving roof.

[0005]

However, the above-mentioned conventional solution means have the following problems. (1) In the snow removal device, there is no problem when only the rail is covered by the rail housing and the rail cover, but when the rail mounting plate fixing the rail is also covered at the same time, or another rail in a direction orthogonal to the rail, etc. If so, the rail housing or rail cover becomes large. Therefore, a large amount of power is required to open and close the rail cover, and it is difficult to open and close the rail cover with a wedge-shaped plow. (2) In the snow removal device, when the rail cover or the rail cover is covered with snow and the rail cover is opened, the surrounding snow may fall onto the rail and the roof member may not be able to move. (3) In the above-described seal structure, when the rail groove has an arch shape, even if the seal groove is provided along the rail groove, the seal water cannot be stored in the seal groove, and thus sealing is difficult. (4) If the above-mentioned sealing structure is adopted for the horizontal rail groove, the sealing water may freeze during the snowy season. Therefore, if the seal water freezes, it may cause a trouble in opening and closing the moving roof, and may damage the seal plate during opening and closing.

Therefore, the present invention not only solves the above-mentioned problems of the conventional method, but also a simple and economical opening / closing roof capable of reliably preventing snow accumulation on the guide rails on which the traveling carriage supporting the roof member travels. It was developed for the purpose of providing the rail cover opening / closing system of.

[0007]

In order to achieve the above object, in the present invention, the rail cover opening / closing system is configured as follows. First, in a retractable roof in which a part of the roof is a movable roof that can be opened and closed, a rail cover that is opened and closed in conjunction with traveling of the movable roof is provided above a guide rail on which the movable roof travels.

Further, the rail cover is configured to be opened and closed in a direction orthogonal to the guide rail.

Further, the rail cover is composed of a plurality of plate-like bodies provided with a hinge mechanism.

As a means for opening and closing the rail cover, a cover wheel guide rail is provided on a movable roof traveling carriage that supports the movable roof and travels on a guide rail. In addition, cover wheels are provided on each rail cover. As the movable roof traveling vehicle travels in this manner, the cover wheels are guided by the cover wheel guide rails to travel, and the rail covers are sequentially opened and closed.

Further, the movable roof traveling carriage is equipped with a cover pushing mechanism for pushing the open rail cover in the closing direction.
