Definitions

  • the present invention relates to support pads mounted on the deck of a craft. More particularly, the support pads provide support to a body portion of a person riding the craft. The support pads have raised portions which inhibit the body portion from slipping from the desired position when the person is riding the craft . The support pad is mounted on the craft so that it is located under the body portion of the person when he or she is in a normal riding position.
  • While the word “craft” is usually associated with a boat, ship or aircraft, the word wherever used in this specification will be taken to encompass surfing craft such as a bodyboard, kneeboard, surfboard or the like which involve a person riding on the deck of the craft . In addition, the word “craft” will be taken to encompass sailboards, jetskies and skateboards.
  • a normal riding position for a bodyboard is one where the rider is in a lying position with the upper portion of his or her body supported from the deck by the forearms and elbows. It is also normal for the rider to hold on to the rails of the bodyboard.
  • the rider places additional weight on one or other side of the board by leaning in the direction it is wished to turn. Turning is facilitated by raising one rail of the craft relative to the other during the redistribution of the rider's weight.
  • At least the forearm which the rider leans upon is subjected to a force acting laterally to the longitudinal axis of the forearm during a turning manoeuvre which can result in the forearm slipping from the desired position on the bodyboard, thereby causing the rider to lose his or her riding position and also, to possibly lose control of the craft.
  • the possibility of slipping during turning is increased in choppy surfing conditions wherein the rider may be bounced on the deck of the craft when encountering "chop" on the face of the wave.
  • An alternate riding position for bodyboard riders which has become increasingly popular in recent years is to crouch in a half kneeling position.
  • the rider places one knee on the deck of the craft, and stabilises him or herself by placing the foot of the other leg on the deck.
  • bodyboard riders use flippers to help them catch waves and usually one flipper is placed substantially flatly on the deck when the rider assumes the half kneeling position.
  • bodyboard riders As with surfboard riders who have preferred "goofy” foot or “natural” foot stances, that is, a stance wherein the rider stands sideways on the deck of the surfboard with their feet positioned apart but with either the right foot in front of the left or vice versa, bodyboard riders also have "goofy” or “natural” stances.
  • a "natural" bodyboard rider is one who crouches with his or her right knee on the deck of the bodyboard.
  • a flat sheet of foamed plastics material such as EVA (ethyl vinyl acetate) can be applied to the deck of the craft to provide a non-slip surface.
  • EVA ethyl vinyl acetate
  • being flat the sheet only provides a non-slip surface for the underside region of the riders body portion in contact with the sheet when the rider is in his or her normal riding position.
  • the EVA sheet does not provide support to side or end regions of the relevant body part to further inhibit the possibility of slipping during a ride.
  • Bodyboards while usually being manufactured from non-slip materials suffer a similar drawback in that their decks are substantially flat.
  • the kick box is comprised of an elongate raised portion upon which the arch portion of the riders foot is placed, and a portion extending perpendicular to the elongate portion against which the rear side region of the riders foot is pressed against during a ride.
  • the T-shaped kick box is positioned on the rear of the craft so that the elongate portion extends along the longitudinal axis of the craft.
  • T-shaped kick boxes suffer a drawback in that they do not provide support to the front and rear of the surfers foot to inhibit the body part slipping from the desired position during a ride.
  • the inventor of the present invention has found that by providing a support pad having raised regions on the deck of the craft, which is positioned to accommodate a body portion of the rider when in the normal riding position, slipping is reduced thereby increasing the likelihood that the rider will complete a turning manoeuvre.
  • a support pad mounted on the deck of a craft so as to receive a body part of a person riding the craft when the person is in his or her normal riding position, wherein the support pad comprises two raised portions which are separated by a trough region for receiving the body part and wherein the two raised portions each have a major axis and are formed so as to extend along opposite sides of the body part when received in the trough region to inhibit movement of the body part in a direction which is transverse to the major axis of each of the raised portions .
  • embodiments of the present invention allow the rider to quickly and easily position him or herself in the normal riding position.
  • a further advantage of the present invention is that slipping from the rider's normal riding position can be reduced due to the provision of support pads having raised portions which are arranged so as to extend along opposite sides of the body part of the rider when received on the support pad. This is a particular advantage in sports such as bodyboarding wherein a rider may attempt a manoeuvre such as a barrel roll wherein the rider actually uses the inside lip of a wave to rotate him or herself through 360°. It is a further advantage that by inhibiting the possibility of the rider slipping on the deck of his or her craft, the safety of the ride is also enhanced. By avoiding possible slipping in critical sections of the ride, the possibility of injury to the rider by falling off his or her craft is lessened.
  • Yet another advantage of the present invention is that damage to the craft on which embodiments are mounted can be decreased.
  • bodyboards have a tendency to flex under the impact of the rider's forearm and elbow when they are being ridden which causes stress lines to appear on the undersurface of the bodyboard. Accordingly, the bodyboard is weakened at the location where the stress lines appear.
  • Support pads mounted on the deck of the craft displace weight placed on the forearm over a wider surface area, thereby inhibiting the flexing of the craft.
  • the added thickness of the support pads absorb forces exerted on the craft through the forearm and elbow of the rider.
  • Yet another advantage of the present invention is that a surfer may position support pads contemplated by the present invention on the deck of the craft to suit his or her particular requirements.
  • an embodiment for supporting the lower knee of a kneeboard rider for instance, can be used for either the right or left knee of the surfer.
  • a forearm support pad designed for a bodyboard rider may be used to support the right or left forearm of the rider.
  • the raised regions of the support pad which inhibit the slipping of the body part extend linearly in the lengthwise direction of the support pad.
  • support pads may be provided which accommodate a forearm portion of the rider while other embodiments may be provided which accommodate the lower knee region of the rider's leg.
  • embodiments designed for use on knee board decks are longer than like embodiments designed for use on bodyboard decks.
  • Support pads may also be provided for use on surfboard or windsurfer decks so as to accommodate the feet of the rider when the rider is in his or her normal riding stance.
  • a surfboard an embodiment may be provided to receive the rear foot of the rider.
  • support pads provided for use on a surfboard for a rider in the standing position extend substantially across the entire width of the deck of the craft.
  • the support pad also has a raised foot arch support region.
  • a similar embodiment may also be provided to accommodate the front foot of the surfer.
  • embodiments of the present invention are manufactured from foamed plastics material, rubberised material, EVA or other suitable material which may be bonded to the surface of a craft's deck.
  • the material from which the support pad is manufactured is generally light weight which enables the overall weight of the craft to be kept to a minimum.
  • a support pad embodied by the present invention is manufactured by passing a three-dimensional planing machine over the chosen material, thereby effectively removing any unwanted material to produce the desired support pad.
  • embodiments may also be produced using injection moulding methods or other moulding techniques .
  • support pads contemplated by the present invention may, for example, be provided by gluing a suitable material onto a contoured substrate . Alternatively, several substantially flat layers may be glued together to form a support pad with raised portions.
  • the surface of the support pad which is to be in contact with the deck of the craft is coated with a material which facilitates the bonding of the pad to the deck.
  • embodiments may be provided which are designed to support only one knee of the rider, for example, it is also envisaged that embodiments may be provided which are designed to accommodate both knees. That is, a single embodiment may have distinct and separate portions designed to accommodate each knee of the rider when the rider is in his or her normal riding position. Likewise, a single embodiment having separate regions designed for accommodating each forearm may be provided for a bodyboard, or a single embodiment may be provided which has separate supporting regions designed for each foot of a surfboard rider or windsurfer. In these support pads, the supporting regions of the pad can be connected by one or more flat, sheet-like regions of the pad.
  • Support pads can also be provided having regions for accommodating each forearm of a bodyboard rider and also a support region for supporting the knee of the rider.
  • the region for receiving the knee may be provided either on the right or left side of the pad, depending on whether the pad has been designed for a "goofy" or "natural" bodyboard rider.
  • support pads contemplated by the present invention are provided in one piece.
  • the support pads may be provided in several pieces which when mounted on the deck of the craft form the support pad. While, it is preferable that each respective piece of the support pad is arranged on the deck so as to be in contact with an adjacent piece of the support pad, the respective said piece may be mounted so as to be spaced apart from the adjacent piece of the support pad. Therefore, a single set of support pad pieces can be arranged on a deck of a craft in order to accommodate the particular dimensions of the relevant body part of an individual rider.

  • Raised ridges 3 each have a major axis which extend lengthwise along raised ridges 3 and which converge towards each other at the front end region of support pad 1. This is more clearly shown in the support pad mounted on the deck of a craft so as to receive the lower knee region of a person as illustrated in Figure 7.
  • raised ridge 3 across front end 4 of the embodiment shown in Figure 5 also inhibits slipping of the rider's knee in the forward direction. It is, however, not necessary that front end 4 be provided with raised ridge 3 or if present, that it be connected to raised ridge portions 3 extending along the periphery of sides 6 and 7.
