The ball is a thin-walled hollow sphere that includes an array of apertures with dimples in a pattern that are concentric to the aperture array. Dimples are provided on the exterior surface of the ball between the apertures with the pattern and dimensions of the dimples varying based on proximity to the apertures. Internal protuberances are provided on the interior surface of the hollow ball such that the interior surface also manages aerodynamic airflow through the ball. Channels are also provided around each of the apertures within the ball which may intersect proximate dimples or be spaced therefrom. The ball also includes apertures having converging and diverging sidewalls that form a venturi shape to increase inflow air into the apertures and outflow air out of the apertures. Finally, the ball also maintains a weight:diameter ratio within a fixed range.

The invention relates to the field of sporting goods, in particular to a hollow ball structure based on a supercritical process, which comprises a foamed ball core, a plurality of hollow cavities are formed inside or outside or inside and outside the foamed ball core, a reinforcing layer is arranged on the periphery of the foamed ball core, a ball surface patch layer is bonded to the periphery of the reinforcing layer, and the foamed ball core or/and the ball surface patch layer can be prepared by using a supercritical foaming process, which ensures the roundness consistency and excellent elasticity and restorability during processing, as well as the roundness consistency after impact of external forces.

Apparatus and associated methods relate to a swimming pool game having a plurality of buoyancy-adjustable balls and a plurality of floatable targets. Each of the plurality of buoyancy-adjustable balls has a water-impervious shell that separates an inside cavity from an outside of the water-impervious shell. The water-impervious shell has a fluid passageway through which a gameplayer can selectively cause fluid transport between the outside of the water-impervious shell and the inside cavity. Each of the plurality of floatable targets has a closed geometrical shape that, when floating on a water surface, defines an inside region of the water surface and an outside region of the water surface. The inside region has an area that is large enough to permit the buoyancy-adjustable ball to reside therewithin.

The present disclosure relates to the technical field of water playing toys, particularly to a toy water balloon, which comprises a flexible shell, a flexible cover and an elastic arm. The flexible shell limits a water storage cavity and an opening connects the water storage cavity and the external space of the flexible shell. The outer contour of the flexible cover is larger than that of the opening to seal the water storage cavity. It is only needed to make the toy water balloon deformation by using the opening to expose the water storage cavity. Which results in higher safety and lower production cost. Compared with the non-magnetic toy water balloon, the flexible cover will stick closely to the inner wall of the water storage cavity so that the toy water balloon disclosed in the present application has good sealing properties.

The present invention discloses a device designed for use in pickleball, racket sports, and similar sports or activities, incorporating a predetermined layer of strips including hydrogel, positioned at the top of a racket, with alternative embodiments featuring a ferromagnetic mechanism as a complementary or standalone mechanism for picking up pickleballs or other objects, streamlining the retrieval process during gameplay, and reducing fatigue.

A toy water ball includes a plurality of petals each having a first edge portion and a second edge portion. Each first edge portion is provided with first magnetic members, and each second edge portion is provided with second magnetic members. When all petals are closed to form a spherical shape, an attraction force is generated between the first magnetic members of each petal and the second magnetic members of the adjacent petal so that the first edge portion of the petal tightly fit the second edge portion of the adjacent petal and a water-carrying cavity is formed. The toy water ball can be closed or opened repeatedly and can be reused. Thus, it is environmentally friendly and clean. Furthermore, the toy water ball can be filled with water in a common water source without a specific pressure, so it can be used in many occasions, and has strong applicability.

The present invention relates to sports balls. A sports ball comprises a surface layer comprising a plurality of panels. The sports ball further comprises a lattice structure extending below the surface layer, wherein the lattice structure comprises a plurality of lattice cells comprising radially extending elements. The lattice cells which are adjacent to the surface layer have at least one dimension which is smaller than an average diameter of the panels.

The present application relates to a toy comprising an internal ball structure comprising a highly resilient material capable of significant bouncing off a hard surface, a plush fabric skin configured to cover the internal ball structure such that the plush fabric exterior does not significantly impact or dampen the ability of the internal bouncing ball structure to bounce when impacting a surface.

A noise-dampening ball for use in the game of pickleball is disclosed. The ball includes a novel layering arrangement which reduces noise generated during play without the need for a player to utilize an alternative paddle while falling within the size and weight standards established by the official body which oversees the sport. The ball demonstrates standard bounce characteristics while allowing the play to be undertaken without the level of noise currently experienced by pickleball players utilizing a conventional ball.
