摘要： Disclosed herein is a multifunctional stand-up paddleboard (MFSUP) comprising a paddleboard, a paddle, and a drive unit. At the stem of the paddleboard is a docking port configured to receive the drive unit that propels the paddleboard. In some embodiments, the paddleboard comprises a rigid midsection, and an inflatable bow and stem. The inflatable portions are inflated during use and deflated then folded over the midsection during storage. A control paddle having control switches send command signals by Bluetooth to the drive unit to control the velocity of propellors. A battery bank is disposed on the midsection and provides power to the drive unit. A solar panel can be included on a superior surface of the paddleboard to supply power to the battery bank. The drive unit is removable from the docking port for propelling a human through a water body. Other features and methods are also disclosed.

摘要： The present invention relates to a set of coupling assemblies comprising a right coupling assembly and a left coupling assembly being configured to be mounted on aboard for board sports and to receive respectively a right boot and a left boot, wherein the right and left coupling assembly comprise an inner receiving unit and outer receiving unit, wherein each inner receiving unit comprises a locking arm which is pivotable about a main inner pivot axis from a locked position to a released position and vice versa, wherein each inner receiving unit comprises a pull mechanism comprising:—at least one elongate interlink member which extends between the two inner receiving units, and—a link pull member configured to engage the boot or the inner boot coupling part and to receive a pull force from the boot or boot coupling part when the boot or boot coupling part is no longer held by the coupling assembly and moves away from the coupling assembly, and to be pulled over a pull distance by said boot or by the boot coupling part, wherein the pull mechanism is configured to transfer the pull force and the pull distance to the at least one elongate interlink member, and to convert the pull distance in an interlink pull distance of the elongate interlink member, and wherein said interlink pull distance pivots the locking arm of the other coupling assembly from the locking position to the released position, thereby releasing the other boot.

摘要： Closed cell chitin foam is provided. The closed-cell chitin foam composition does not absorb water, is biodegradable, and is mechanically characterized by a density range of 16 to 800 kg/m3, closed-cell pore sizes ranging from 50 microns to 1 mm, an elastic modulus of 3 to 175 MPa, and a tensile strength of 0.15 to 6.5 MPa. The chitin is at least 70% acetylated. In one aspect, the foam is enclosed in a shell e.g. in the form of a surfboard. Chitin foam according to this invention is fully biodegradable. The chitin foam overcomes the current problems with foams that contain polyurethane and polystyrene, and which are manufactured from petroleum-based sources. Petroleum based foams are not renewable, have an adverse impact on our environment, and pose significant health hazards to those who manufacture them. The chitin foam with its water-based manufacturing process and naturally sourced chitin, solves these problems.

摘要： The swivel lock quick release device is adapted to selectively attach a user to a sports equipment. The sports equipment may be watersports equipment, such as a surfboard, a kite surfing apparatus, a stand-up paddle board, sailing equipment, a wake board, etc., or land sports equipment, such as fishing, camping, climbing, animal collars or leashes, tactical rifle apparatus, and hunting equipment. The swivel lock quick release device can have a pull release and a protrusion, the pull release and the protrusion being adapted to be selectively engaged in a locked position is provided. A slide handle, a portion of the pull release, is adapted to be selectively moved in a coaxial direction by the user to disengage the pull release and the protrusion. The pull release can also be adapted to rotate or swivel around the protrusion.

摘要： A biomechanically adapted dual direction sportsboard. This stance-specific sportsboard accommodates a rider's stance, whether they are a “regular-foot” or a “goofy-foot.” This stance-accommodating dual direction sportsboard allows the rider much greater control since the board accommodates the specific biomechanics of the rider's dominant stance, whether their preference is to ride with their left foot in front or their right foot in front. The dual direction sportsboard has rails which are offset from each other, which allows for a rider with fixed foot positions to significantly change the trim of the board by shifting from heel-side rail to toe-side rail or back to heel-side rail. This provides the rider much greater control over the board while performing surfing-style maneuvers, especially with the board attached to their feet. Additionally, for kiteboarding, the offset rails allow for greater windward ability than with legacy designs.
