The present invention discloses a hockey flooring tile having a top smooth surface for passing pucks and one or more interconnecting mechanisms allowing for an interconnection with another tile. A locking mechanism is also positioned within the interconnecting mechanism allowing for a tile to be locked to another tile. The tile disclosed in the present invention also has a bottom surface having support points to support a tile when a weight is placed on the tile.

A retaining wall system for elevating a retaining wall panel of a portable ice skating rink. The retaining wall system includes a first support member and a second support member spaced apart from the first support member. The retaining wall system includes a flexible sheet extending between the first support member and the second support member. The retaining wall system includes a water impermeable liner supported by the flexible sheet. A support member for elevating a retaining wall panel of a portable ice skating rink. The support member includes a base arrangement configured to engage a mounting surface and a height elevating section extending from the base arrangement. The height elevating section having a first receiving area configured to receive a wall panel. A surface extends between the base arrangement and the height elevating section. The surface has a plurality of mounting areas configured to receive a lateral brace member.

A synthetic ice panel system for use on a ground surface includes plurality of substantially flat panels that mutually interlock to form a rink, such as for ice skating. Each panel includes a top surface, a bottom surface adapted for resting on the ground surface, and a peripheral edge. The peripheral edge includes a plurality of interlocking tabs and recesses operative to mutually interlock with adjacent panels. Each panel is preferably made with a high-density polymer infused with a lubricant. As such, ice skates and the like are able to slide with relatively low friction on the top surface of the panel. Weather permitting; the panels may be inverted in some embodiments wherein the bottom surface of each panel includes a cooling channel containing a cooling tube through which a coolant flows to freeze water resting on the panel, thereby forming a layer of ice above the panel.

Ice rink assemblies include a plurality of panels and support brackets. Each support bracket may include a floor support and an upright coupled to the floor support. The upright may include a central body, a plurality of wings extending laterally outward from the central body, and a slot formed in at least one wing. At least one fastener may extend through each panel, and may be positioned within a respective slot associated with a respective support bracket to couple a panel to the support bracket. Methods of assembling ice rinks may include positioning at least one fastener through a panel and into a respective slot associated with a support bracket, and tightening the fastener to constrict the fastener and the panel against the support bracket. Other aspects, embodiments, and features are also included.

A liquid cooling system for an outdoor ice forming surface provides a geothermal heat pump that has a refrigeration circuit with a compressor that is disposed between a cold tube section and a hot tube section. An outdoor structure has an upward facing ice forming surface that is configured to retain a body of ice, where a coolant line is provided at or near the ice forming surface. A fluid pump is coupled with the coolant line and is configured to circulate liquid through the coolant line and over the cold tube section of the geothermal heat pump to dispense heat before being recirculated to the ice forming surface of the outdoor structure.

A grass ski carpet, comprising a plurality of spiral grass assemblies arranged regularly, wherein each spiral grass assembly comprises: a plurality of row brushes arranged in a same direction, wherein each row brush comprises a base bar and multiple pieces of spiral grass, the multiple pieces of spiral grass are spaced apart and fixedly connected to a first surface of the base bar, the multiple pieces of spiral grass are arranged in a same direction, each of the multiple pieces of spiral grass has a grass tip, a grass stem, and a grass root, the grass stem is curved, the grass tip is bulbous, and rotation directions of all the multiple pieces of spiral grass are same; and a base plate fixedly connected to each of the multiple row brushes through a detachable structure, so that the multiple row brushes are arranged on a surface of the base plate.

A portable ice rink includes a wall formed of multiple wall members linearly disposed adjacent to one another to form a piecewise continuous wall that encloses a desired area, and also includes a chain of links disposed on the outside of the wall members for reinforcement. The rink may further include a waterproof tarp extending underneath the wall members and folded upwards along the outer side of the wall, with its edge tied to the change of links. The tarp can contain water which then freezes to form a skating surface. Curved wall members are provided to form a rink with round corners. Each wall member is a discrete unit, made of molded plastic, and having a hollow interior which can be filled with water (or other ballast). Each wall member is designed with stiffening features to maintain the flatness of its inner surface after filling.
