Abstract: A steerable body board is provided that can be easily and safely to be manipulated to change the moving directions of the steerable body board and can be safely slow down or stopped. The steerable body board contains a board body, a bottom plate and a control unit. The board body has a channel therethrough. The bottom plate is installed next to a bottom surface of the board body and overlays an end of the channel. The bottom plate has plural parallel ribs on a bottom surface of the bottom plate. The control unit is connected to the bottom plate through the channel for steering the bottom plate.

Abstract: This invention relates to a layered composite material, which comprises a foam skin, a plastic plate and a plastic film. The foam skin has a density in a range of 1.5 to 12 PCF and a thickness in a range of 1 to 6 mm. The plastic plate is laminated to a top surface of the foam skin without adhesives and the plastic plate has a thickness in a range of 0.1 to 2 mm. The plastic film has a surface laminated to a bottom surface of the foam skin without adhesives and the plastic film has a thickness in a range of 0.01 to 0.15 mm. In addition, layered composite material further comprises a fabric layer laminated to other surface of said plastic film without adhesives.

Abstract: A slider resists erosion due to moisture, dirt and ultraviolet of sunlight and protects a pattern or the bonded surface from wear and tear. The slider contains a foam core, a top layer, a pattern, and a bottom layer. The foam core has a top surface, a bottom surface and edge surfaces. The top layer is a composite layer heat laminated to the top surface and edge surfaces of the foam core. The pattern is formed within the top layer and visible from outside of the top layer. The bottom layer is heat laminated to the bottom surface of the foam core.

Abstract: A slider that can resist corrosion of moisture, dirt and ultraviolet of sunlight and prevent the pattern therein from wear and tear. The slider also provides a smooth touching feeling to users. The slider mainly containing: a polyethylene foaming board, a first polyethylene foaming skin, a first plastic film, a second polyethylene foaming skin and a second plastic film. The polyethylene foaming board having a top surface, a bottom surface and edge surfaces. The first polyethylene foaming skin contains an inner surface and an outer surface. The inner surface of the first polyethylene foaming skin is bonded with the top surface and the edge surfaces of the polyethylene foaming board. The first polyethylene foaming skin has a foaming rate less than a foaming rate of the polyethylene foaming board. The first plastic film is bonded with the outer surface of the first polyethylene foaming skin. The second polyethylene foaming skin contains an inner surface and an outer surface.

Abstract: An adjusting strap structure for one of a pair of swim fins includes an elongated adjusting strap having two sides each having two distal ends, two first snapping members each mounted on a respective one of the two distal ends of one of the two sides of the adjusting strap, and at least one second snapping member mounted on the one side of the adjusting strap and located between the two first snapping members for detachably engaging with the two first snapping members. Each of the two distal ends of the adjusting strap extends through a respective one of the two side walls of the foot pocket, and then each of the two first snapping members are detachably engaged with the at least one second snapping member.

Abstract: A bodyboard includes a board made of expended polyethylene and a protection layer heat-laminated around the board. The protection layer has at least 0.01 mm thick and with ultraviolet inhibitor and anti-oxidant added therein. The bodyboard has a serrated surface so as to prevent the bodyboarders/surfers from slipping.
