    • A stadium that is adapted for open use during good weather as well as for covered use during poor weather includes a foundation and a pair of movable end roof members that are movable between first, retracted positions and second, operational positions for covering first and second end areas, respectively, of the stadium. The stadium also includes a center roof member that is movable between a retracted position and an operational position for covering a center area of the stadium. All of the roof members are supported for movement between the retracted positions and the operational positions by a guide and support assembly that includes at least one rail member that is secured to the foundation and a plurality of independently suspended follower assemblies that are mounted to the respective roof member. Each of said follower assemblies include a wheel member that is positioned in contact with the rail and a resilient member that is interposed between the wheel member and the roof member, so that each of the wheel members is independently suspended with respect to the other wheel members. This creates a number of advantages, including that it makes alignment easier to achieve and maintain, and that it allows the guide and support assembly to be constructed with a large number of small wheels and to have a relatively low profile, which makes the system attractive from both an aesthetic and a structural standpoint.
    • 在恶劣天气期间适于开放使用的体育场,以及在恶劣天气期间被覆盖使用的体育场包括可在第一缩回位置和第二位置之间移动的基座和一对可移动的顶部屋顶构件,用于覆盖第一和第二端的操作位置 区域分别是体育馆。 该体育场还包括可在缩回位置和用于覆盖体育场的中心区域的操作位置之间移动的中心屋顶构件。 所有的屋顶构件被支撑以通过导向和支撑组件在缩回位置和操作位置之间运动,所述导向和支撑组件包括固定到基座的至少一个轨道构件和多个独立悬挂的从动组件,其安装到相应的 屋顶成员 每个所述随动件组件包括与所述导轨接触定位的轮构件和介于所述车轮构件和所述车顶构件之间的弹性构件,使得每个所述车轮构件相对于所述其它车轮构件独立地悬挂 。 这产生了许多优点,包括使得对准更容易实现和维护,并且它允许引导和支撑组件由大量的小轮构成并且具有相对低的轮廓,这使得系统具有吸引力 从美学和结构的角度来看。
