ADDRESS FOR SERVICE: Patent Atto* 2 INVENTION TITLE: Surfboard having embedded reinforcing mesh The following statement is a full description of performing it known to me/us:of this invention, including the best method IP Australia Documents received on: 0 0 2 2FEB 1999 (DBatch No: Batch No: E= la The invention relates to a surfboard having a reinforcing mesh layer solidly embedded in the board body.

Typical surfboards comprise a number of layers secured together by such as adhesive materials, so as to form the surfboard. However, the number of layers are normally secured together by adhesive materials such that the number of layers may be easily disengaged 10 from each other after use.

It is accordingly an objective of the invention to provide a surfboard which includes a reinforcing mesh layer solidly embedded in the board body for greatly increasing the strength of the surfboard.

According to the present invention there is provided a surfboard comprising: a) a body including a bottom portion, b) a plate secured to the bottom portion of the body and formed by a material, and c) a reinforcing mesh embedded in the plate and including a plurality of mesh openings, the material for forming the plate being engaged into the mesh openings for allowing the reinforcing mesh to be solidly embedded in the plate.

The plate includes a lower portion, the reinforcing mesh is embedded in the lower portion of the plate. The reinforcing mesh includes a thickness -2equals to that of the plate, for allowing the material for forming the plate to be filled in the mesh openings of the reinforcing mesh.

The reinforcing mesh includes a thickness greater than that of the plate and includes an upper portion engaged into and embedded in the body. The reinforcing mesh may also include a lower portion extended downward and outward of the plate.

"In the drawings:- FIG. 1 is an exploded view of a surfboard; FIG. 2 is a partial perspective view of the oeeee •surfboard, in which a portion of the surfboard is cut off for showing the inner structure of the surfboard; FIG. 3 is a cross sectional view taken along lines 3-3 of FIG. 2; and eeFIGS. 4 and 5 are cross sectional views similar to FIG. 3, illustrating the other applications of the surfboard.

Referring to the drawings, and initially to FIGS.

1-3, a surfboard comprises a board body 10 of foamable materials, such as ethylene vinyl acetate copolymer (EVA), polyethylene or the mixture thereof. A plate 20 is secured to the bottom of the body 10 and is made of stiffing material, such as ethylene vinyl acetate copolymer (EVA), polyethylene or the mixture thereof, which includes a greater stiffness than that of the body 10. A reinforcing mesh 30 is to 3 be embedded in the plate 20 and includes a number of mesh openings 31. The mesh 30 is preferably a woven member formed by plastic or fibers.

For embedding the mesh 30 in the plate 20, the plate 20 and the mesh 30 and/or the body 10 are disposed in and hot-pressed by a mold device. The plate and/or the body 10 will be melted when they are heated, such that the mesh 30 may be embedded in the plate 20 after the plate 20 is melted and such that the 10 material for forming the plate 20 (in fluid or melted status) may be engaged into the mesh openings 31 (FIG.

such that the mesh 30 may be solidly embedded in the plate 20 without additional adhesive materials.

The mesh 30 that is embedded in the plate 20 may 15 greatly increase the strength and the flexibility of the board and may prevent the board from being easily broken. The mesh material 30 includes a weight no greater than that of the plate 20, such that the strength of the plate 20 may be increased without increasing its weight. The body 10 and the plate 20 may also be solidly secured together during the hotpressing process without any additional adhesive materials, such that the body 10 and the plate 20 may be taken as an integral board body.

The mesh 30 includes a thickness equals to that of the plate 20 (FIG. 4) or greater than that of the plate (FIG. 5) in which the mesh 30 includes an upper 4 portion 32 engaged into and embedded in the body 10 and a lower portion 33 extended outward of the plate 20 for forming a coarse bottom to the plate 20 and for increasing the maneuverability of the surfboard.

Accordingly, the surfboard includes a reinforcing mesh solidly embedded in the board body for greatly increasing the strength of the surfboard.

Throughout this specification and the claims which follow, unless the context requires otherwise, the word 10 "comprise", and variations such as "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.

Claims

1. A surfboard comprising: a body including a bottom portion; a plate secured to said bottom portion of said body and formed by a material; and, a reinforcing mesh embedded in said plate and including a plurality of mesh openings, said material forming said plate being engaged into said mesh openings thereby solidly embedding said reinforcing mesh in said plate, wherein said reinforcing mesh includes a thickness at least equal to that of said plate, for allowing the material forming said plate to be filled in said mesh openings of said reinforcing mesh.

2. A surfboard according to claim 1, wherein said plate includes a lower portion, and said reinforcing mesh is embedded in said lower portion of said plate.

3. A surfboard according to claim 1 or claim 2 wherein said reinforcing mesh includes a thickness greater than that of said plate and includes an upper portion engaged into and embedded in said body.

4. A surfboard according to any of the preceding claims wherein said reinforcing mesh includes a thickness greater than that of said plate and includes an lower portion extending downwardly and outwardly of said plate. A surfboard substantially as herein described with reference to the accompanying drawings. ooooo 0 0.
