A strip subassembly (2) which may be used to form a takraw ball or a similar woven ball, includes a backbone strut (4) and one or more pads (6) attached to the backbone strut (4). In the woven ball, the pads (6) form an even surface which is comfortable for the player.

A toy ball which emits sounds as it is rolled and including a ball body and a plurality of mechanically-operated sound producing tubes carried within the ball body, each sound producing tube including a sound-producing device which moves by the force of gravity, and each sound producing tube lying along a longitudinal axis, in which the axes are transverse to one another so that the sound producing devices emit sound when the ball is rolled along various axes. The ends of the sound-producing tubes are held by sleeves that are molded as integral parts of the ball body.

A tennis ball including a spherical core. The spherical core including an outer surface and a raised wall integrally molded as part of the outer surface.

A luminous safety ball including an inner glowing body and a foam sphere covering the inner glowing body is provided. The inner glowing body is not a perfect sphere, the foam sphere has a non-uniform thickness, and light emitted by the inner glowing body passes through the foam sphere and permeates through a surface of the foam sphere to form light with different brightness thereon.

A heavy duty, repairable weighted ball used for exercising capable of being loaded to heavy weights and being used on uneven or rough surfaces. The shell of the ball being constructed by a plurality of pieces of material in two layers: an inner encompassing layer capable of holding the weighted material and an outer layer holding the inner layer together. The pieces are joined together such that on being damaged they can be replaced individually. The pieces can be composed of a variety of materials, including repurposed or recycled material.

A tennis ball including a spherical hollow elastomeric core having a specific gravity of less than 1 and a thickness of at least 4.5 mm, and a textile layer covering the spherical elastomeric hollow core. The spherical hollow core has an initial internal pressure of no greater than 5 psi. The tennis ball has a first tennis ball rebound height when measured at a first time when the tennis ball is unused and a second tennis ball rebound height measured after the tennis ball is exposed to atmospheric pressure for four months following the first time and is unused. The second tennis ball rebound height being at least 96% of the first tennis ball rebound height.
