    • According to the present disclosure, a playyard top rail includes a left rail and a right rail mounted to pivot about a pivot axis relative to the right rail. The playyard top rail further includes a rail lock associated with the left and right rails. The rail lock is configured to lock the right rail to the left rail upon movement of the left and right rails to an in-line erected position and movement of the rail lock in a first direction along the pivot axis to a rail-locking position. Once the rail lock is moved in an opposite second direction along the pivot axis to a rail-releasing position, the left and right rails are free to pivot relative to one another about the pivot axis to assume a side-by-side collapsed position. An extensible cord is coupled at one end to the left rail and at another end to the right rail and supported in the middle on a lock housing containing the rail lock to define a bowed fabric support overlying a portion of the left and right rails.
    • 根据本公开,游乐场顶部轨道包括左轨道和右轨道,其安装成围绕相对于右轨道的枢转轴线枢转。 游乐场顶部轨道还包括与左右轨道相关联的轨道锁。 轨道锁被配置为在左和右轨道移动到直线竖立位置并且沿着枢转轴线沿着第一方向移动轨道锁定到轨道锁定位置时将右轨道锁定到左轨道。 一旦轨道锁沿着枢转轴线沿相反的第二方向移动到轨道释放位置,则左轨道和右轨道相对于彼此绕枢转轴线自由枢转以呈现并排的折叠位置。 可伸长的绳索在一端连接到左导轨,另一端连接到右导轨,并在中间被支撑在一个包含导轨锁的锁壳上,以限定一个覆盖在左右轨道的一部分上的弓形织物支撑。
