One example embodiment includes a mobile action sports ramp. The mobile action sports ramp includes an incline portion connected to a vehicle portion by a hinge. The incline portion includes a lower incline portion connected to an upper incline portion by a hinge. The lower incline portion folds onto the upper incline portion and the incline portion then rests upon the vehicle portion when the mobile action sports ramp is collapsed and capable of transportation. The lower incline portion unfolds into alignment with the upper incline portion and the incline portion then raises up when the mobile action sports ramp is erected and capable of use in various action sports. Methods for erecting and collapsing a mobile action sports ramp are also provided.

[Problem to be solved] To provide a wave making apparatus for surfing that can make a so-called tubular curling wave suitable for surfing and in which a breaking portion and about to break portion are arrayed in a line. [Solution] The wave making apparatus comprises: a water carrying bucket 110 opened at the front, including a bottom plate and a side surface plate, and capable of holding water in a portion of an inner space thereof; a supporting structure 120 that supports the water carrying bucket 110; and a transmission apparatus 130 that moves the water carrying bucket 110 forward at a predetermined speed. The water carrying bucket 100 supported by submerging the water carrying bucket 110 under waterline of the pool such that the front of the water carrying bucket 110 faces the play area of the pool. The transmission apparatus 130 moves the water carrying bucket 110 forward along a track extending forward the play area with the water carrying bucket 100 kept below the waterline. The water held in the water carrying bucket 100 is carried forward and launched, and thereby an isolation traveling wave suitable for surfing is formed.

An apparatus for playing games is envisaged. It includes a structure that defines boundary of the apparatus. There are multiple elements placed on the apparatus that define player locations. The apparatus can of any size and shape and can be used by players for playing various games. The players can use movable devices separately or the devices can be associated with players for the purpose of playing different games. Multiple lanes are placed at pre-defined positions on the structure for forming junctions in order to control and guide movement of players or moveable devices or movable devices associated with players. These junctions and lanes together form a number of turns that change direction of movement of players during the game play. The apparatus includes transparent bodies, speed regulators, marking units for marking the players and counters for counts number of markings for the purpose of playing different games.

A movable dasher board system optimizes user safety in a hockey rink or similar arena. A bottom structure, provided by a sliding bottom surface or roller assembly, has low friction characteristics, typically a .sub.s of 0.05 or less with respect to ice if a sliding surface, or if roller bearings an effective coefficient of rolling friction 0.04 or less. A dasher board assembly is operatively connected to and extends upwardly from the bottom structure. Biasing and impact force absorbing devices (such as pneumatic or hydraulic or spring-encasing telescoping tubes, or foam, gel, or compression springs) bias the bottom structure and dasher board assembly to a desired position and absorb the impact of a human hitting the dasher board assembly to minimize the possibility of injury to the human. The system may be installed in a pre-existing rink or other arena.

A portable ice skating rink structure kit that includes a liner, sidewall, a wicket or slotted anchor block for supporting the sidewall, and sidewall connectors and liner clips. The skating rink may be used on hard or soft surfaces. The sidewall is supported by wickets for use with soft surfaces, such as ground, and slotted anchor blocks for use with hard surfaces, such as pavement. The slotted blocks may have slots of different depths to compensate for uneven ground underneath the skating surface and maintain a sidewall of even height. Once the sidewall is supported, a liner is draped over the playing surface and the sidewalls create a pool of water. The liner may be held in place with liner clips and staples. When temperatures fall below freezing, a smooth sheet of surface ice is created.
