Abstract
A bodyboard is provided having a top riding surface with a centralized torso-supporting region of generally hourglass shape and perimetric purchase-enhancing region which surrounds the torso-supporting region.
Claims22
A bodyboard for use in supporting a rider during travel in ocean surf, the bodyboard comprising:
- an elongate plank defining a semi-rigid bodyboard core with a riding surface, a planing surface, a forward end, a rear end and a pair of elongate laterally-opposed side edges;
- and
- a multi-layer topskin covering the riding surface of the bodyboard core, the topskin including a first layer and a second layer, the second layer defining an hourglass-shaped aperture through which the first layer protects to define a centralized torso-supporting region of generally hourglass shape and a purchase-enhancing region which extends substantially along a perimeter of the torso-supporting region to impede uncontrolled rider shift.
A bodyboard for use in supporting a rider during travel in ocean surf, the bodyboard comprising:
- an elongate plank defining a semi-rigid bodyboard core with a riding surface, a planing surface, a forward end, a rear end and a pair of elongate laterally-opposed side edges;
- and
- a multi-layer topskin covering the riding surface of the bodyboard core, the topskin including a first layer having a first resiliency and a second layer having a second resiliency which is less resilient than the first resiliency, the first layer covering the riding surface of the bodyboard core and the second layer covering the first layer, the second layer defining a centralized hourglass-shaped aperture through which the first layer projects to define a topskin with a centralized torso-supporting region and a perimetric purchase-enhancing region which surrounds the torso-supporting region, the torso-supporting region having increased resiliency relative to the purchase-enhancing region.
A bodyboard for use in supporting a rider during travel in ocean surf, the bodyboard comprising:
- an elongate plank defining a semi-rigid bodyboard core with a riding surface, a planing surface, a forward end, a rear end and a pair of elongate laterally-opposed side edges, the planing surface having a substantially planar glide region and a pair of elongate propulsion channels which transition gradually from the glide region adjacent opposite side edges of the bodyboard core, and the rear end having a pair of rearwardly-projecting side tail-fin portions and a rearwardly-projecting center tail-fin portion which define an undulated tail;
- and
- a multi-layer topskin covering the riding surface of the bodyboard core, the topskin including a first layer having a first resiliency and a second layer having a second resiliency which is less resilient than the first resiliency, the first layer covering the riding surface of the bodyboard core and the second layer covering the first layer, the second layer defining a centralized aperture through which the first layer projects to define a topskin with a more-resilient centralized torso-supporting region and a less-resilient perimetric purchase-enhancing region, the purchase-enhancing region defining an elbow pad with an elbow well topographically contoured to enhance purchase of the rider's elbow and a palm grip to enhance purchase of the rider's hand, and a palm w ell immediately behind the palm grip to receive a carpal portion of the rider's hand both in a first orientation with the rider's palm overlying the palm grip and in a second orientation with the rider's palm gripping the side edge of the bodyboard core.
A bodyboard for use in supporting a rider during travel in ocean surf, the bodyboard comprising:
- an elongate plank defining a semi-rigid bodyboard core with a riding surface, a planing surface, a forward end, a rear end and a pair of elongate laterally-opposed side edges;
- and
- a multi-layer topskin covering the riding surface of the bodyboard core, the topskin including a first layer having a first resiliency and a second layer having a second resiliency which is less resilient than the first resiliency, the first layer covering the riding surface of the bodyboard core and the second layer covering the first layer, the second layer defining a centralized aperture through which the first layer projects to define a topskin with a centralized region and a perimetric region which surrounds the centralized region, the centralized region having increased resiliency relative to the perimetric region.
A bodyboard for use in supporting a rider during travel in ocean surf, the bodyboard comprising:
- an elongate plank defining a semi-rigid bodyboard core with a riding surface, a planing surface, a forward end, a rear end and a pair of elongate laterally-opposed side edges;
- and
- a topskin covering the riding surface of the bodyboard core, the topskin including a centralized torso-supporting region of generally hourglass shape and a perimetric purchase-enhancing region which surrounds the torso-supporting region to impede uncontrolled rider shift, the purchase-enhancing region defining a forward palm grip adjacent a forward comer of the bodyboard core, the forward palm grip having enhanced surface friction characteristics to provide for capture thereof by the rider's palm, the purchase-enhancing region further defining a palm well immediately behind ergonomically contoured to receive a carpal portion of the rider's hand in a first orientation with the rider's palm overlying the palm grip and being ergonomically contoured to receive the carpal portion of the rider's hand in a second orientation with the rider's palm gripping the side edge of the bodyboard core.
A bodyboard for use in supporting a rider during travel in ocean surf, the bodyboard comprising:
- an elongate plank defining a semi-rigid bodyboard core with a riding surface, a planing surface, a forward end, a rear end and a pair of elongate laterally-opposed side edges, the planing surface having a substantially planar glide region and a pair of elongate propulsion channels, each propulsion channel extending along the planing surface adjacent one of the side edges;
- and
- a topskin covering the riding surface of the bodyboard core, the topskin including a centralized torso-supporting region of generally hourglass shape and a perimetric purchase-enhancing region which surrounds the torso-supporting region to impede uncontrolled rider shift.
A bodyboard for use in supporting a rider during travel in ocean surf, the bodyboard comprising:
- an elongate plank defining a semi-rigid bodyboard core with a riding surface, a planing surface, a forward end, a rear end and a pair of elongate laterally-opposed side edges, the riding surface including a pair of elongate guides which extend along the riding surface adjacent opposite side edges of the bodyboard core, thereby opposing passage of the rider over the side edges;
- and
- a topskin covering the riding surface of the bodyboard core, the topskin including a centralized torso-supporting region of generally hourglass shape and a perimetric purchase-enhancing region which surrounds the torso-supporting region to impede uncontrolled rider shift.
