3 BACKGROUND OF THE INVENTION
4 1. Field of the Invention The present invention relates to a slider, and more particularly to a 6 slider that can function as a surfboard, a bodyboard, a floating board, a skiing 7 board, a sliding board or the like.
8 2. Description of the Related Art 9 A conventional slider comprises a main body made of a polyethylene foam material, and a plurality of handgrips mounted on a 1 ~ periphery of the main body to facilitate a user holding the slider.
However, the ~ 2 main body made of a polyethylene foam material reflects greater costs in 13 material and trimming.
14 For reducing the cost, another conventional slider comprises a main body made of a polystyrene foam material, which reflects reduced costs in 16 material and trimming because the polystyrene foam material is easily to be 17 molded into particular shapes. However, the main body made of polystyrene 18 foam material is easily worn out and broken; therefore, a wearable plastic 19 plate attached on the bottom of the main body is necessary for strengthening 2o the durability of the slider. In addition, the main body made of a polystyrene 2t foam material is difficult and incompatible bonded to the plastic plate without z adhesives. Therefore, the slider made of polystyrene foam material and having 2 a strong structure is in great demand.
The primary objective of the present invention is to provide a slider having a shape that is easily molded.
6 Another objective of the present invention is to provide a slider, '7 wherein the foam board is integrally formed of a polystyrene foam material so s that the shape of the foam board is formed easily and conveniently, thereby 9 saving the manufacturing time and decreasing costs of fabrication.
A further objective of the present invention is to provide a slider, 1 t wherein the whole face of the foam board of the slider is heat bonded to an 12 interface layer, which has characteristics for heat bonding the polystyrene 13 foam board to polyethylene materials without adhesives, such as polyethylene 14 foam skins and polyethylene plates/films. Therefore, the bottom of the foam board could be heat bonded to a wearable plastic plate and the top of the foam 16 board could be heat bonded to a patterned plastic film without any adhesives.
17 More particularly, the slider of the present invention comprises a 18 foam board, an interface layer, a top layer and a bottom layer. The foam board 19 is made of polystyrene foam material and has a top face, a bottom face and 2o edges. Furthermore, the top face of the foam board having a riding portion and 21 the bottom face of the foam board having a rail portion opposite to the riding 22 portion. The rail portion of the bottom face of the foam board has a plurality of 1 foam rails internally protruded therefrom and the foam rails are parallel with 2 each other.
3 In addition, the interface layer is heat bonded to the top face, the 4 bottom face and the edges of the foam board without adhesives. The top layer is heat bonded to the top face and the edges of the foam board via the interface 6 layer completely. The top layer could be a composite layer composed of either 7 patterned polyethylene film and/or patterned polyethylene film/foam skin.
8 The bottom layer is heat bonded to a bottom face of the foam board 9 completely via the interface layer, so as to cover the foam rails of the rail 1 o portion of the bottom face of the foam board as well. Accordingly, the bottom 11 layer has a plurality of recessed joints respectively by heat bonding to the ~ 2 foam rails of the rail portion of the bottom face of the foam board.
Therefore, 13 the foam rails of the slider are provided for guiding a sliding direction to a 14 user.
Because the polystyrene foam material could be easily molded into 16 varied shapes, the costs and the time are saved during manufacturing.
n7 Further benefits and advantages of the present invention will 18 become apparent after a careful reading of the detailed description with 19 appropriate reference to the accompanying drawings.

3 In addition, the interface layer is heat bonded to the top face, the 4 bottom face and the edges of the foam board without adhesives. The top layer is heat bonded to the top face and the edges of the foam board via the interface 6 layer completely. The top layer could be a composite layer composed of either 7 patterned polyethylene film and/or patterned polyethylene film/foam skin.
8 The bottom layer is heat bonded to a bottom face of the foam board 9 completely via the interface layer, so as to cover the foam rails of the rail 1 o portion of the bottom face of the foam board as well. Accordingly, the bottom 11 layer has a plurality of recessed joints respectively by heat bonding to the ~ 2 foam rails of the rail portion of the bottom face of the foam board.
Therefore, 13 the foam rails of the slider are provided for guiding a sliding direction to a 14 user.
