A method and a court for playing a sporting match are provided. The court includes a springboard floor in a generally rectangular shape. A wall surrounds the floor and has a lower portion of padded material and an upper portion of transparent material. Sidelines and baselines are disposed around the periphery of the floor. Tackle zones is disposed between the base lines and the sidelines. An o-zone is in the center of the floor. A pair of goals are on opposing sides of the court, each goal comprising a backboard, central hoop, and two backboard goals defined by the backboard. Aa pair of goalie boxes are disposed on opposing sides of the court under each of the goals. Pairs of three-, four-, and five-point lines disposed on opposite sides of the floor. Penalty boxes disposed in the wall.

A retractable surface system, which is installed within an opening in a surface and a method of installing the retractable surface system within the opening in the surface. A mat is introduced into the opening. Secured within the mat are inner piers, which include a vertical sleeve to facilitate the lowering of a retractable surface within the opening, and outer piers, which include a vertical support column with upper and lower stops, which stabilize the retractable surface in a raised or lowered position within the opening. Supporting the retractable surface in the opening is a platform. A drive motor is secured to the platform and drives one or more systems for raising and lowering the platform within the opening.

The present invention relates to an inclined structure of a court floor having a new structure for easily collecting automatically supplying balls used in practice. According to an inclined structure of a court floor according to the present disclosure, the ball used for practice can be rolled down outwardly along the slope of the court, and then be collected in the collecting ditch and gathered in one place, so there is no need to collect scattered balls separately.

A modular ramp system includes a ramp component and a connector releasably joined to the ramp component. The ramp component has first and second inclined surfaces and a connecting portion positioned between the first and second inclined surfaces. The connector has a bottom side formed with a first and second coupling section connectable to the connecting portion. The connector is positionable in a first position in which one of the first and second coupling sections is releasably joined to the connecting portion of the ramp component and the other of the first and second coupling sections is adapted to releasably couple to a ramp or an external structure, and a second position in which the first and second coupling sections are releasably joined to connecting portion of the ramp component.
