Abstract

A surf board device comprises a rigid board (1) and a flexible expandable chambered container (2), when pressure is applied to said container by a user the container is deformed propelling the surfboard along. The container may be made from rubber or PVC welded sheeting and filled with a fluid substance which is moved round the container in response to the applied pressure. The container may have two chambers (6) one provided on each side of the rigid board, connected by a passage passing through a hole (4) in the centre of the rigid board. A layer of buoyant material (3) such as polyethylene foam may be provided on either side of the rigid board while the 3-layered construction may have a waterproof cover (5). Figure 1

Description

SURF BOARD DEVICE

BACKGROUND OF THE INVENTION

[0001] This invention relates to a surfboard device.

[0002] Where you find water, you may find people participating in sports and other leisure activities. Surfing and body boarding have both become popular in recreation and sport circles. This invention has many similarities to a surf or body board. However this invention has unique features that enable its use in a wider range of conditions that known surf or body boards are suited to.

SUMMARY OF THE INVENTION

[0003] The objective of this invention is to provide a surf board device comprises a rigid board and a flexible expandable chambered container, when pressure is applied to said container by a user the container is deformed propelling the surfboard along.

[0004] In another preferred embodiment, the container may be made from rubber or PVC welded sheeting and filled with a fluid substance which is moved round the container in response to the applied pressure.

[0005] In another preferred embodiment, the container may have two chambers one provided on each side of the rigid board, connected by a passage passing through a hole in the centre of the rigid board.

[0006] In another preferred embodiment, a layer of buoyant material such as polyethylene foam may be provided on either side of the rigid board while the 3-layered construction may have a waterproof cover.

[0007] The present invention can be more fully understood by reference to the following description and accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Fig.l illustrates in perspective, an exploded diagram showing the components of the board; [0009] Fig.2 illustrates a side view of the board showing how the flexible, expandable, chambered container may intersect the semi rigid sheet via an aperture; [0010] Fig.3 & Fig.4 Illustrate in side view, compression and expansion of the flexible, expandable, chambered container when force is applied in the direction of arrows A.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Referring to the drawing (Fig. 1), this invention contains a flexible, expandable, chambered container 2. Each chamber is segmented into compartments 6, that may be proportionately filled with a fluid substance (not shown), each chamber may intersect the semi rigid sheet 1 via an aperture 4 enabling at least one compartment of each chamber to have presence on either side of the board. These components may be sandwiched between or surrounded by a buoyant means 3 and if rewired may be contained within a fitted cover 5.

[0012] Each chamber may be interconnected with each other. Alternatively, each chamber may be connected via a tube or pipe (not shown). Referring to the drawings (Fig.2 & Fig.3), As the operator applies force to one or more of the compartments 6, in direction 'A', these compartments compress forcing other compartments to expand, thus deforming the board. This alters the buoyancy characteristics of the board and changes the effect water has upon the dynamics of the leading edge and following body of the board. These internal and external forces, combined with operator movement, propel the board through water.

[0013] This invention may benefit by passing a number of segmented compartments 6 of the chambers in the flexible, expandable, container through an aperture 4 in the semi rigid sheet 1 .This sheet may limit expansion to the opposite side of the board to which force had been applied. The flow of fluid substance between the segmented compartments 6 in the chambers in the flexible container 2 may be inhibited by the restrictive size and shape of the aperture 4 in the semi rigid sheet or by the introduction of a known flow inhibiting means (not shown).

[0014] These two components may have a covering of buoyant means 3 either totally or partially, if partial this may allow more expansion of the flexible, expandable chambered container 2 through any predetermined space in the buoyant material designed to enhance performance of the board. This invention may benefit from having a fitted covering 5 to contain the components. Alternatively the components may be fused together.

[0015] Buoyant means 3 for this invention could be manufactured from sealed cell polyethylene foam, blown polystyrene or gas inflated compartments manufactured in PVC. The semi rigid sheet 1 used to separate the segmented compartments in the flexible, expandable chambered container could be manufactured from polypropylene; glass or carbon fiber reinforced plastic sheet. The flexible, expandable chambered container 2 could be manufactured from rubber or PVC welded sheeting. Alternatively it could be molded in vinyl or plastic. The fitted cover 5 if required could be vinyl, plastic, rubber, PVC, woven polypropylene or any suitable material that may withstand the effects of water. The fluid substance proportionately filling the flexible chambered container may be any form of liquid or gas.
