Definitions
- the present invention relates to surfcraft.
- the present invention relates to a craft for riding on the surface of the water.
- the craft of the present invention is in the form of a bodyboard or the like. Such craft may be propelled by the motion of the waves or surf.
- Buoyant boards have been utilised as surfcraft.
- bodyboards have developed from the original "boogie boards" and a variety of surfcraft such as bodyboards are currently available.
- bodyboards are formed from panels of closed cell polymeric foam.
- surfcraft are just over a metre in length and about half a metre in width.
- these surfcraft are awkward to store and to transport due to their size and shape.
- Inflatable surfcraft have been produced and are generally similar in construction to inflatable beds and have only a single skin. Such inflatable craft generally lack the necessary stiffness and hydrodynamic properties to provide an acceptable level of performance to make them feasible alternatives to surfcraft made out of rigid materials such as closed cell polymeric foam.
- a craft for supporting a rider on the water in the form of an elongate, substantially planar member having a top riding surface, a bottom, planing surface wherein said planar member comprises an inner inflatable bladder secured within an outer sleeve wherein said sleeve comprises the top riding surface and the bottom, planing surface.
- the inflatable bladder may preferably be constructed from any suitable material. Suitable materials are capable of being sealed to form an air tight bladder. Desirably the materials used to form the bladder are sufficiently flexible to be rolled up in a deflated condition but are sufficiently rigid in an inflated condition such that a rider may be supported on the surfcraft without significant deformation. We have found that by minimising the deformation of the surfcraft the hydrodynamic properties can be maintained. For example, it is preferred that a heavy duty PVC ranging from 18 to 30 gauge PVC be used to form the inflatable bladder. The PVC is ultrasonically welded.
- the inflatable bladder preferably includes valve for inflating and deflating the bladder. A variety of valves may be suitable.
- a retractable valve is particularly preferred so that is does not protrude from the surfcraft.
- a vinyl stem retractable valve may be used.
- the valve may be configured to engage with a mechanical pump. It is preferred that the inner inflatable bladder be shaped substantially in conformity with the desired shape of the surfcraft although the outer sleeve may be used to constrain the inflatable bladder to a desired shape.
- the inner inflatable bladder is of ribbed construction so as to retain a planar shape.
- the inflatable bladder may also be seamed or bonded in other configurations whereby a relatively planar elongate bladder is produced once the bladder is inflated.
- the inflatable bladder may be removed from the outer sleeve for cleaning, replacement or repair.
- the bladder may be removed from outer sleeve via an opening in the tail which is sealed with a hook and loop fastener such as VelcroTM.
- the outer sleeve or cover may serve to constrain the inflatable bladder to the desired shape.
- the outer sleeve has an upper riding surface and a lower planing surface.
- the upper riding surface and the lower planing surface may be joined directly or may be preferably joined by a side gusset.
- the outer sleeve may include a variety of optional features.
- a leash attachment may be provided on the nose of the surfcraft.
- handles and knuckle guards may also be provided on the nose of the surfcraft.
- leash attachment, handles and knuckle guards be formed integrally with the outer sleeve.
- a leash attachment, handles and knuckle guards are provided integrally on the outer sleeve at each corner of the nose of the surfcraft.
- the outer sleeve is a sewn and laminated sheath made from a heavy-duty nylon fabric. A nylon fabric ranging from 240 to 840 denier is preferred.
- the outer sleeve may preferably include on the upper riding surface a panel on which a rider may be located.
- the panel may be formed from padded material and provide the rider with a degree of comfort and protection. It is particularly preferred that the panel is formed from a soft material such as neoprene or terry-cloth material and act as a body protector.
- the upper surface may also include provision for the inflation valve of the inflatable bladder to be extended therethrough for ready access for inflation and deflation without having to remove the bladder from the sleeve.
- the leash attachment may be in the form of an aperture extending through a handle.
- the leash attachment may be formed as an aperture through the outer sleeve.
- the handle may be attached to the outer sleeve or be formed integrally therewith.
- the handle may also be attached to or formed integrally with the inner inflatable bladder and extend through the outer sleeve.
- the handle may be formed from closed cell polymeric foam.
- the knuckle guard preferably extends from the handle and is formed from a soft material such as neoprene on terry cloth.
- the bottom, planing surface of the outer sleeve may be formed from heavy-duty nylon fabrics ranging from 240 to 840 denier.
- the bottom, planing surface may include fins or other configurations adapted to provide improved hydrodynamic properties.
- the bottom, planing surface may include a ridgid panel wherein said rigid panel may further include fins or the like.
- the tail of the bottom, planing surface includes a drainage port for allowing water to be removed from inside the outer sleeve.
- the drainage port may preferably be in the form of a plasticised nylon mesh.
- any water that collects behind the outer corner and the bladder may be drained by standing the surfcraft upright. It is preferred that the drainage port extends across the width of the tail of the surfcraft.
- the outer sleeve includes a closure system such as a Velcro closure to retain the inner inflatable bladder securely within the outer sleeve.
- a closure system such as a Velcro closure to retain the inner inflatable bladder securely within the outer sleeve.
- the surfcraft of the present invention is substantially planar having a narrowed nose section and a tail in the form of a swallowtail or bat-wing.
- the surfcraft of the present invention may be deflated and compacted for storage and transport.
- the bottom, planing surface is of rigid material the surfcraft may be stacked in a deflated state.
- the bottom planing surface is of flexible material, such as heavy duty nylon or of a flexible, semi-rigid material, the surfcraft may be deflated and rolled up for storage and transport.
