摘要： An apparatus for supporting one or more theatrical panels and, in a more specific aspect, a carriage assembly adapted for such task in association with a horizontal track having an upper guide surface and a lower guide surface, provide horizontal movement quietly, smoothly, with low frictional resistance and in a highly-linear fashion with low rock and sway. A horizontal track comprising an upper guide surface and a lower guide surface supports a carriage assembly having a plurality of upper guide wheels and a plurality of lower guide wheels. The upper guide wheels are supported in rolling contact with the upper guide surface and the lower guide wheels are supported in rolling contact with the lower guide surface. The axles supporting the upper guide wheels are preferably horizontally offset from vertical lines extending through any of the axles supporting the lower guide wheels. The guide wheels are preferably resilient at least at the surface and grooved to engage the guide surfaces.

摘要： Reusable performance stage deck segments provide rapid assembly with assured alignment. Segments interlock to form a substantially continuous performance surface. The reusable segments have a top, a bottom (preferably with low-friction pads), a first pair of opposed sides, a second pair of opposed sides, and an upper deck surface supported by the top of the frame. Each pair of opposed sides on basic structural segments includes guide means to vertically align the sides with adjacent deck segments having complimentary guide means. Two types of guide means are provided, one also facilitates horizontal alignment, preferably by providing a projecting member (e.g., a removable tapered rod) on one side and a receptacle for a like member on the opposed side. The other type includes an elongated tongue element on one side and an elongated groove element on the other, to facilitate sliding movement between engaged complimentary members. Cable track deck segments include tracks for cables.
