A training device having a platform for receiving at least one person; at least one anchoring point for fastening a securing means that secures the person on the training device; a vertical rotation axis Z, about which the training device can be mounted rotatably or is mounted rotatably. The anchoring point is arranged at or above the height of the buttocks region of the person, and the training device is rotatable about this rotary axis Z by means of forces acting on the platform.

A water skills training device to facilitate water skills training for infants under the supervision of caretakers in shallow water environments is disclosed. The device includes a base to be placed in a shallow water environment, a receptacle placed onto the base and configured to receive and support an infant, and a floatation cushion removably engaged to the base and configured to support an infant's head or upper torso during water skills training. The floatation cushion can be easily removed or added as desired.

An apparatus configured to extend onto and retract from a body of water a flotation mat. The apparatus includes first and second spaced apart support members such that both support members include an upper and a lower end. The spaced apart support members are secured to a boat dock by mounting hardware. First and second vertically slidable members are slidably mounted to the first and second spaced apart support members. The apparatus also includes a rotatable shaft that extends between the upper ends of the first and second slidable members. A sprocket assembly is mounted to one of the ends of the rotatable shaft to facilitate either manual or powered rotation of the shaft for purposes of extending or retracting the mat onto or off the body of water.

A water game apparatus having a buoyant seat platform with seats on opposing ends and handles on opposing sides to enables game participants to sit on the two opposing seats while other game participants jostle and rock the seat platform by holding onto and moving the handles. The game players try to maintain their balance and remain on the buoyant seat platform while being bucked and jostled. The last game player to remain on the buoyant seat platform is the winner. The seats may be concave depressions in the buoyant seat platform to provide some support of the game players and to prevent them from simply siding off the platform. The handles may be embedded in the seat platform of configured in a channel formed by a seat portion and water portion of an assembly. The water contact surface may be convex in shape from side to side.

The invention relates to an aquatic game device comprising a structure having two ends which are each fitted with a base module, said structure being sufficiently deformable so as to allow the relative movement of said modules, the density of the modules being designed to allow the immersion of said device in water with the modules arranged such that they stand on a subaquatic surface, and the density of the structure being designed so as to be able to suspend said structure in the water according to at least one game configuration.

A swimming assistance accessory includes a holder to hold the accessory during swimming; a float allowing the water to exert, on the accessory, a vertical force resulting from buoyancy opposing gravity; and a weight allowing the barycenter of the holder to be maintained substantially below the surface of the water when the accessory is in a balance position in water.

A ball, sphere or article holding system includes a first hollow semi-hemisphere or shell formed of a resilient material and having therein a plurality of apertures, the semi-hemisphere or shell including a first hinge element and, diametrically opposed, a first selectable closure element. The system also includes a second hollow semi-hemisphere or shell formed of a resilient material and also having a plurality of apertures, the second semi-hemisphere or shell including a second hinge element which is complementally proportioned, disposed and engagable relative to the first hinge element. Diametrically opposed therefrom is a second closure element which is complementally and press or snap-fittably engagable by the opposing closure element of the first semi-hemisphere or shell. Closure between the responsive closure elements may be enhanced by the use of a ring slip-fittably passing between complementally disposed apertures within and between the closure elements. The surface of an article held within the system is offset from interior surfaces of the semi-hemispheres or shells by nubs, stubs of the like. Articles held within the sphere may include bells and treats for pets.

An aqua resistance dumbbell comprises a tubular wall that provides a bore for receiving a user's hand from each end of the bell. A rod is located within the bore and extending laterally across the bore to be gripped by a user with one or both hands from one or both ends of the bore. The dumbbell has a plurality of longitudinal fins extend along the tubular wall on an outer side of the tubular wall, and at least one lateral fin that extends laterally at least part way around the tubular wall. An aqua resistance fin assembly comprises two fin components and at least one fastening member for fitting the fin components to a user's limb in a side-by-side configuration around the limb. Each fin component comprises a base adapted to fit against a user's limb and adapted to be secured to the user's limb by the fastening member, and at least two longitudinal fins and at least one lateral fin on an outer side of the base.
