The human powered hydrofoil bicycle includes multiple subsystems integrated together including a structural frame subsystem with associated steering and tiller module, a hydrofoil subsystem to provide vehicle lift, and a powertrain subsystem. The structural frame subsystem may be fitted with buoyancy modules to provide the overall vehicle with a near neutrally buoyant character. The structural frame subsystem also supports a seat for an operator and provides structural support for the steering and tiller module for the hydrofoil subsystem and the drivetrain subsystem. The hydrofoil subsystem includes multiple hydrofoil elements at lowermost portions of the vehicle. These hydrofoil elements generally include in a preferred embodiment a larger rear foil and a smaller front foil. The powertrain subsystem generally includes pedals rotatably supported on the vehicle at a convenient location for engagement and driving by feet of an operator. Power transmission elements extend from the pedals down to a prime mover such as a propeller.

The utility model discloses a water hammock which comprises a head support, a foot support and a bottom supporting cloth. The bottom supporting cloth is arranged between the head support and the foot support. Both sides of the bottom supporting cloth are provided with buckles. The left side of the bottom supporting cloth is connected with a left arm support through the buckle. The right side of the bottom supporting cloth is connected with a right arm support through the buckle. The utility model can be disassembled and assembled, which is convenient for transportation and storage, and can also be installed and matched with different arm supports or sleeve cloths according to different use demands, which is more practical.

A personal flotation system provides a horseshoe shaped float that is buoyant and can be used in a number or positions to float a person on the water and retain a beverage. The horseshoe shaped flotation device has a left and right armrest that extend out from an arced shaped closed end and dual cup holder, on the extended end of the armrest, has an cup cylinder to retain a beverage in the vertical orientation and an end cup holder to retain a beverage in an orthogonal orientation to the cup cylinder. The flotation device may have an extending strap that couples the left and right armrests together to secure the horseshoe shaped float around a person's torso.

Woven inflatable devices and methods for making woven inflatable devices are provided. The woven inflatable devices include a laminated sheet with inflatable regions that when inflated cause the laminated sheet to transform from a planar shape to a three-dimensional shape such as a chair, container, or kiteboard harness.

An apparatus for mounting a pedal propulsion system to a watercraft, having a mount portion configured to be attached to the watercraft, a link support, and upper and lower links pivotally connected to the link support and to the mount portion. The link support and upper and lower links are configured to form part of a four-bar linkage arrangement and to simultaneously move together between an extended, operable position for operating the propulsion system, and a retracted, stowed position elevated above the extended position, for loading, transporting, unloading and/or launching the watercraft in the water. A column clamp is configured for selectively fixing a drive column of the pedal propulsion system to the link support, wherein the drive column, the link support and the upper and lower links are configured to simultaneously move together between the extended and retracted positions.

The present invention relates to a chest float, comprising a float body; and a support pad, wherein both sides thereof are in detachable connection with both sides of the inner edge of the float body; first and second back limit pads are respectively extended from the two sides of the support pad, the first and second back limit pads are in detachable connection, and a wrapping space is enclosed by the support pad, and first and second back limit pads; when support pad is demounted from the inner edge of the float body from the two sides, the use state of the chest float is switched to the use state of a waist float. By means of the detachable design of the support pad, the chest float realizes the switching between the lying prone state and standing state of an infant, and is adapted to infants of different ages.
