A racket for ball sports includes: a first half-shell including a first head portion having a first impact wall, a first handle portion extending from the first head portion and a first contour wall extending around the first head portion; a second half-shell, coupled to the first half-shell, includes a second head portion having a second impact wall, a second handle portion extending from the second head portion and a second contour wall extending around the second head portion, the second contour wall being joined to the first contour wall; a central core of a first deformable material positioned between the first and second impact surfaces; and a peripheral core including a contour element positioned around the central core, the peripheral core of a second deformable material being positioned between the first and second impact surfaces in contact with the first and second contour walls.

A ball machine provides a sequence of shots to a player on a racquet court, where each shot corresponds to a predefined shot described by initial parameters that may be modified by difficulty modifiers. The returned shot of the player is monitored and evaluated by the ball machine to determine if the returned shot meets various success criteria, such as location, speed, height. When the player returns one or a certain amount of shots meeting the success criteria, the difficulty of the shots provided to the player is increased, which repeats until the player is no longer successfully able to consistently return shots that meet the success criteria. At this time, the evaluation routine may be terminated, the player's skill level is assessed.

The present teachings generally include sound dampening devices, systems, kits, and methods for pickleball and the like. In an aspect, a pickleball paddle includes one or more layers having sound dampening properties. In another aspect, a paddle accessory featuring one or more sound dampening materials may be engaged with a pickleball paddle to enable quieter play using the paddle. In yet another aspect, a ball for pickleball play includes one or more layers having sound dampening properties. And, in another aspect, an accessory featuring one or more sound dampening materials may be engaged with a ball to enable quieter play using the ball.

An example pickleball paddle comprises a striking blade and a handle connected to the striking blade at a connecting part. A bottom edge of the striking blade, located on one or both of a left side and a right side of the handle, is orthogonal to a center axis of the striking blade at the connecting part and the handle, or extends below the connecting part. The center axis of the striking blade may be different from a center axis of the handle. In another example pickleball paddle, the center axis of the striking blade is different from the center axis of the handle, and, either the bottom edge of the striking blade is orthogonal to the center axis of the striking blade at the connecting part and the handle, or extends below the connecting part.

The present teachings generally include flexible pickleball paddles and/or frames thereof. In an aspect, a frame of a paddle includes a region adjacent to a throat portion of the paddle that is thinner than other regions of the frame, e.g., thicker regions disposed along its sides, top, and/or handle. The lack of material in this portion of the framee.g., disposed directly above the handlemay provide advantageous flexing of the paddle during play (e.g., how fast the paddle can return to the original shape after being flexed), improving power characteristics, control, feel, responsiveness, and/or the like. Moreover, a gap formed by the lack of material in this portion of the frame can provide a region for enhanced weight control (e.g., by filling the gap with a weighted material), and/or for enhanced sound or vibration control (e.g., by filling the gap with a sound dampening and/or vibration dampening material).

A pickleball racket includes a racket frame, a racket face and a handle. The handle is connected to one end of the racket frame, the racket frame is arranged around the racket face, the racket face and the racket frame enclose to form a filling cavity filled with elastic components. The pickleball racket has excellent elastic property, improves energy absorption and rebound efficiency, and improves the user's usage experience.

A removable striking surface for a sports paddle for facilitating playing with the paddle, wherein the removable striking surface comprises a flexible film. The flexible film is comprised of a least one layer. The removable striking surface is coupled to the striking surface of a sports paddle using an adhesive which is located on the rear surface of the removable striking surface. Further, the removable striking surface may and provides the sports paddle with a textured surface. Further, the removable striking surface has a shape configured to cover at least a portion of the head of the sports paddle.

An example embodiment provides a pickleball paddle comprises a striking blade and a paddle holding part. The paddle holding part is configured to have a hand inserted therein and/or to have the hand temporarily attached thereto.

A pickleball warming device generally includes a housing, a heating assembly, and a power source. The housing includes a chamber designed to temporarily hold a plurality of pickleballs therein and a cover assembly to open and close the chamber. The heating assembly is positioned in the housing and adjacent the chamber to heat pickleballs in the chamber to a temperature sufficient to minimize damage to pickleballs when playing in colder temperatures. The power source is positioned in the housing and operatively connected to the heating assembly to supply electricity to the heating assembly.

An apparatus and methods are provided for a quiet pickleball. The quiet pickleball includes a spherical body comprising a sound dampening layer surrounding an inner plastic layer. Holes extend through the spherical body into a hollow interior. The sound dampening layer reduces the noise exhibited when the pickleball is hit with a paddle. The sound dampening layer can be attached to the exterior of a plastic pickleball or can be co-molded or injection molded during forming the pickleball. In one embodiment, the sound dampening layer is a felt pad adhesively attached to the exterior of the pickleball. A die enables cutting the felt pad to a shape that enables covering the exterior of the pickleball. An indexing jig enables attaching the felt pad to the pickleball such that holes in the felt pad are aligned with holes in the pickleball.
