Free Cage is a fenced-in enclosure on allsides with openings wide enough for free entry and exit for children and adults. The invention is a function of space intended for outdoor play and entertainment (outdoor space) so that inside the space will be inserted figures—props that will be movable in dimensions larger than the openings and thus will not be possible to extract. The purpose of this invention is to satisfy the needs of a space with movable props—outdoors propelled without being able to be dislocated, stolen and yet always accessible to all users and visitors. The possibilities for play and entertainment in this fenced-in space are endless and depend on the elements and props that will be placed inside the space. The invention can be used both individualy and by multiple persons ath the same time.

A method of playing a game, comprising providing a playing surface that is generally rectangular with rounded corners having a length dimension of approximately 200 feet or less and a width dimension of approximately 85 feet or less, providing a pair of opposing goal nets, each associated with one end of the playing surface where each goal net defines a scoring area above said playing surface. providing a first team and a second team of players, each team alternatively having possession of the game ball and having an objective to score points by sending the game ball into the goal net. providing the first team and the second team each include six players and a goalie, where each of the six players wear inline skates except the goalies where players from the first team and the second team are free to collect the game ball after deflecting off the barrier.

Provided is a water track marker (1) for marking a sports track, such as a water ski track, on a water surface (20). The water track marker comprises at least a first marker ejector (11) configured to eject marker projectiles (2) towards the water for creating an instant marking (3) on the water surface (20) upon impact with the water surface (20). Provided is also a method for marking a sports track and a towing boat comprising said water track marker.

A method of installing a binder-based overlay system may include contacting a layer of geotextile fabric to a surface of a substrate and applying a primer layer to a surface of the geotextile fabric. Two or more binder layers including infill particles may be applied over the primer layer. A resurfacer layer followed by one or more color layers may be applied over the two or more binder layers. The primer layer, one or more binder layers, resurfacer layer, and two or more color layers may cure upon application to form a monolithic layer upon the substrate.

A roller skating rink for players to play a skating game utilizes one or more game implements. A skating track is made from a plurality of track sections. The roller skating rink includes concave channel sections on one side of the track sections and has a lower end and an upper end that are substantially vertically aligned. One or more propelling devices are each adapted to propel one of the game implements into the roller skating rink. One or more scoring receptacles are situated for receiving one or more of the game implements therein proximate the upper end of the concave peripheral wall. A method of game play is further disclosed.

The multisport space includes a plurality of different fields for goal sports and net sports. There is a first square or rectangular area for goal sports delimited by a vertical wall. The first goal sports area has a goal sports field in which the goals are vertical and extend from ground level. There is a goal sports field in which the goals are horizontal and placed at a certain height. The panels of the vertical wall form nets for a plurality of net sports fields arranged on either side of the panels of the vertical wall. Extensions of panels, leading from their respective implantation axes, also form nets for net sports fields.

Various embodiments for a panel that may be combined with other similar panels to form a padding layer of an athletic field, or other surface, are disclosed. The panel for use in a padding layer of a panel system includes a male locking element configured to form a dove-tail connection with at least one adjacent panel. The dove-tail connection includes a male locking element of the panel coupling with a female locking element of the at least one adjacent panel and forming an interference fit between the male locking element and the female locking element. A space is proved between the male locking element and the female element when coupled that permits thermal expansion of the panel.
