초록

A multi-activity complex incorporates a plurality of activity floors, each of which has an associated playing surface and is selectively movable between a storage position, located below an event staging or activity area, and an in-use position located in the activity area. A system is provided for alternatively shifting the activity floors between the respective storage and in-use positions. The shifting system includes a lift assembly for vertically moving the activity floors into and out of the activity area and a second mechanism for laterally shifti...
