摘要： An inflatable standup paddleboard having a split deck pad. The split deck pad may allow for easier storage and greater customization options for the inflatable standup paddleboard. The split deck pad may also be removable from the body of the standup paddleboard through integral grooves within the body of the inflatable standup paddleboard. The structural integrity and buoyancy may be further improved with a crisscrossed structure of strings within the interior of the inflatable standup paddleboard.

摘要： The present invention relates to a novel water sports device that allows a user to perform water skiing and other activities while sitting on the device. The device includes a toboggan style structure positioned atop a pair of water skis. The pair of skis are secured to the underside of the toboggan using a plurality of panels or supports so that the skis partially overlap and extend beyond the edges of the toboggan. Each of the pair of skis comprise a binding which is sized and configured to accommodate a foot of the user while sitting on the toboggan. The device provides enhanced balance, buoyancy, and floating capability, and also comprises a backrest for supporting the back of the user while enjoying the device on the water.

摘要： A manufacturing method contemplates performing vacuum-assisted resin infusion to enclose an elongated core within a cured composite laminate without employing a mold. Not relying upon an external mold enables the process to be efficiently performed for core shapes that are manufactured in low volumes. Typical resin infusion processes utilize flow media that induces bag bridging during vacuum draw in order to provide gaps facilitating resin flow. However, popular flow media also tends to impart directional aggregate forces during vacuum draw, which forces can deform the core since no mold is being used. To avoid unequal and non-dispersed directional forces from deforming the elongated core, a flow media is employed that is configured to disperse and/or reduce such forces. Some such flow media may be knitted so as to allow overlapping strands to slide over one another. Other flow media may ensure that strands are interleaved so that no one strand or group of strands is disposed outwardly of other strands along a substantial length of the strands, thus dispersing bag bridging forces in several directions and avoiding directional aggregate forces. However, such flow media may have inhibited resin flow relative to popular high-flow flow media, and thus new strategies have been developed to ensure appropriate wetting of fibrous reinforcement. An adjustable brace can also be employed to restrain the elongated core from deflecting during application of vacuum and/or resin infusion.

摘要： An improved wooden surfboard and method of construction comprised of pre-cut layers of wood longitudinally arranged of predetermined thicknesses (502-512) stacked and bonded together following the shape of the surfboard. The longitudinal layers include slots (208) to slide and embed multiple transverse ribs (210) in perpendicular direction for joining the longitudinal layers together. The bonded longitudinal layers form a pre-shaped plank with the geometrical features of the surfboard without the need of carving and shaping the surfboard's geometry. A smooth finish is achieved after a light sanding of the pre-shaped plank. In some embodiments the longitudinal layers have predetermined perforations (202) to create air chambers (204) reducing the weight of the surfboard. Other embodiments are as described and shown.

摘要： An improved water sports board, which is composed of a structural element at the base, an intermediate layer of deformable and waterproof elastic foam, in the upper area pressure plates, and inside structural columns. The structural element is light and has high resistance. Thickness of the structural element and their reinforcements can be modified and calibrated without restriction, achieving great flexion and torsion characteristics. The elastic middle layer allows to maintain the required volume and improves the dampening properties. The pressure plates receive the pressure of the surfer feet and transfer this pressure through the structural columns to the structural element. The intermediate elastic layer, pressure plates and structural columns do not affect board flexion or torsion

摘要： In a water sports board structure (3), a composite material shell (20) encloses a core (10) including a shaped body (11) made of a foam material obtained by a mixture of polylactic acid, preferably between 60% and 80% by weight, and of a polymer selected between an aliphatic polyester and an aliphatic/aromatic co-polyester. For the foam material, a biodegradable Ecovio EA material is preferably used, in particular Ecovio® EA200 or ECOVIO® 80EA2394EXP. In an exemplary embodiment, the shaped body (11) incorporates at least one, or preferably two cork longitudinal stringers (13) spaced apart from each other by about half the cross width of the core (10). The shell (20) can comprise a fibre layer (21,24), preferably of basalt fibres, impregnating with a resin, which can optionally form a resin layer (23,26) outside the fibre layers (21,24). A further resin-impregnated fabric layer (22) can be present between the core (10) and the fibre layer (21) of the shell (20). The above foam materials allow manufacturing boards that are at least 20% lighter than the conventional boards including polystyrene foam cores, and that have suitable elasticity while having excellent impact strength and/or resistance to abrasion, such a combination leading to high-performance water sports boards. Moreover, polylactic acid as well as the above aliphatic polyesters or aliphatic/aromatic co-polyesters are fully biodegradable, which allows environment-friendly disposal of the water sport boards of the invention, for instance, by composting, without forming any special waste.
