Abstract: Adjustable pickleball paddle includes a paddle body comprising a flat planar core permanently attached to and positioned in between a pair of identical external faces on both flat sides thereof, and a handle configured to hold and manipulate the paddle, the handle extending from the core and oriented to be co-planar therewith. The flat core is configured to removably accept a first insert or additional inserts to fit within a thickness of the flat core, the first and/or additional inserts are configured to increase the stiffness of the flat core when placed therein, as well as the weight of the paddle. Individual adjustments to the twist weight and swing weight allow customization of the paddle for the individual needs of the player.

Abstract: Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club head includes a body portion being hollow to define an interior cavity, a filler material in the interior cavity, a face portion, and a back portion having a back wall portion. The back wall portion includes a first external ledge portion and a second external ledge portion, and a perimeter groove below the external ledge portion. The golf club head also includes a removable mass portion coupled to the back wall portion. The face portion includes a back surface with a perimeter portion, a face recess portion and a back groove portion in the face recess portion. The filler material is coupled to the face recess portion and the back groove portion. Other examples and embodiments may be described and claimed.

Abstract: A tool includes a tool head with a utilization surface. The tool also includes a counter device responding to an impact applied to the utilization surface. The counter device has a memory, a microcontroller controlling operation of the counter device, an indicator, and an energizer connected to the microcontroller, which in response to the impact applied to the utilization surface, produces an electric current energizing the counter device to make a modification in the memory and provide information about the cumulative count of impacts in the memory via the indicator to a user.

Abstract: A sports paddle including a head portion coupled to a handle portion. The head portion includes at least one core layer positioned between first and second face plates. The first and second face plates have first and second outer surfaces, respectively. The head portion defines a plurality of through-head portion holes extending from the first outer surface to the second outer surface and a plurality of grooves extending into the first and second face plates. The head portion can include first and second face plates having first and second outer surfaces, respectively, and the handle portion can include a grip. Each of the first and second outer surfaces can include a roughened region and a generally smooth region. The smooth region of the first outer surface can space apart the grip from the roughened region of the first outer surface.

Abstract: A ball-striking sole for a table tennis paddle comprises a flexible coating (118) of elastic material, one face (135) of which is lined with elastically deformable pimples (120) which protrude from said face. The cross section of said pimples is greater in their region (122) of attachment to this coating than in the region close to their opposite end (124) and the side wall (125) of these pimples has a concave curved profile over at least a part of the height of the pimple between these two regions. This sole is used particularly successfully in a table tennis paddle in which the face of said sole (112) lined with pimples (120) is directed towards the inner side of the blade (115) of the paddle such that the free ends (124) of the pimples, the lateral surface of which has a concave curved profile (125), are pressed against a layer (126) of elastic material, secured to the blade, the modulus of elasticity of which is much lower than that of the elastic coating (118) of the sole.

Abstract: The splattle paddle comprises a main housing with a handle secured thereto. A stretchable, flexible material is secured at an outer edge to the main housing. A button is secured centrally of the main housing to which one end of a linear stretchable cord is secured. The opposite end of the cord is secured to a holding apparatus, such as a clip. In use, a water-filled balloon or ball is secured to the holding apparatus and the water-filled balloon is then hit by the paddle until the balloon breaks.

Abstract: A perforated bat for playing games such as paddle tennis, tether ball and others, has a monolithic unstressed striking head which comprises a pair of outer lattices which form the striking surfaces; and these lattices are joined by a third internal core lattice which has at least one longitudinal and one lateral web spanning the two outer lattices.
