A system for reversibly converting stadiums into multifunctional infrastructure by removing the pitch and storing it in a pit (6), the pitch having a set of trays (1) having a total length equal to the pitch in a longitudinal direction of the pit, which are moveable, self-supporting and have layers of soil, irrigation and turf; a set of transport trolleys (2) for lifting and moving each tray (1) from its position on the pitch to the pit (6); a set of retractable trellises (5) that can be unfolded on the pit (6), for the entry of each tray (1) from above the pit; an elevator system (8) inside the pit (6) to move each tray to its final position, in storage, or on the pitch; and a storage system (7) for storing each tray in a fixed and stable position.

The present invention relates to arenas with selectively configurable seating arrangements for selectively providing viewing access to an event floor from an event level hospitality area. The arena includes a plurality of seats, at least some of which are removable. The plurality of seats is selectively arrangeable in tiered seating sections around the event floor to define one of a first seating arrangement and a second seating arrangement. The tiered seating sections include first and second opposing curved seating sections, and first and second spaced apart straight seating sections. The first straight seating section is located in front of the hospitality area. When the seats are selectively arranged in the first seating arrangement, the first and second straight seating sections are disposed generally parallel to each other and extend between the first and second curved seating sections so as to define an obround distribution of seats around the event floor; and viewing access of the event floor from the hospitality area is impeded by the first straight seating section. When the seats are selectively arranged in the second seating arrangement, the first straight seating section and the first curved seating section are omitted leaving the second straight seating section extending to the second curved seating section; and viewing access of the event floor from the hospitality area is unobstructed.

There exists a number of youth development programs centered on sports programming. Some of these programs operate on a platform of revitalizing neighborhood spaces to improve community engagement by creating a space for youth to enjoy sports. Oftentimes these neighborhood spaces include restrictions or the surrounding community has needs (like lighting and seating) which are unmet or under-met. Envisioned is a system approach to addressing these needs wherein a wide variety of custom solutions can be produced from prefabricated, modular, and portable components that interface with existing amenities (if any) so to enrich the youth experience and better achieve program objectives. This modular approach provides a common infrastructure for different spaces, different sports, and different levels of play.

A turf sports field with a plurality of turf modules (100) having an upper turf surface and peripheral turf edges (5). The turf modules are deployed by means of a remotely operated or autonomously operated lifting and transport vehicle (103), which is provided with a lifting arrangement. When installed, the turf modules (100) are positioned adjacent previously installed turf modules, with a tolerance gap (105) between adjacently positioned turf edges (5) of different turf modules.

This invention deals with portable modular equipment for area assembly multisport and/or multipurpose and method of setting up multisport area and/or multipurpose, ideal for sports such as soccer, volleyball, basketball, handball or other sports, as well as physical, educational and recreational activities that primarily aim at the production of knowledge related to teaching/learning/leisure; the modular equipment (10) is completely portable and conformed by one, preferably, two modules (20), each of them to the format preferential use of a container (21) and able to pack a set of parts structural (CP) that correspond to half of a multisport/multipurpose area (AP); said set of pieces (CP) is basically composed of a fencing bottom link (30A), two side fences (30B), at least four modular bleachers (40), at least one access structure (30C), accessories goal posts (60), volleyball nets (61) or others, at least one self-contained set for generating lighting (70) and Wi-Fi signal, synthetic grass or modular floor coverings (GS), as well as components of mounting type connectors, screws and others.

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.
