Abstract
Abstract An arrangement for floor gymnastics, particularly for the martial arts, has a floor element and a plurality of wall elements movable between an extended and a retracted position. The wall elements are located in the retracted position in accordion-like relationship with respect to each other. Fluid-operated drive means are provided for moving the wall elements between the retracted and extended positions. The movable wall portions include the portions which at least partially form a floor, a roof and longitudinal walls of the arrangement respectively. The wall elements in the extended position together bound an inner space which is free of supports. Some of the wall elements are hingedly connected with one another.
