A strung bat for use in playing cricket includes an elongate handle for a user to hold and a blade elongated in the direction of the handle. The blade includes a perimeter defining an internal space that is strung with an array of strings for hitting a ball. The perimeter frame has a leading edge and an opposing trailing edge, and the array of strings lies in a plane that may be substantially aligned with the leading edge of the frame or is closely adjacent to the leading edge of the frame. An apparatus for playing the game using the strung bat is also disclosed.

A frame of a lacrosse head includes a ball stop, a scoop, a left sidewall, and a right sidewall. Each of the left and right sidewalls includes a top rail, a bottom rail, a first cross-strut extending between the top and bottom rails thereof, and a second cross-strut extending between the top and bottom rails thereof. The second cross-struts are disposed closer to the ball stop than the first cross-struts. The second cross-strut of the left sidewall is longer than the first cross-strut of the left sidewall and extends from the top rail to the bottom rail in the direction of the scoop to the ball stop. The second cross-strut of the right sidewall is longer than the first cross-strut of the right sidewall and extends from the bottom rail to the top rail in the direction of the scoop to the ball stop.

A racket frame has an inner thick part (28) having an outer surface (12), an inner surface (14) and a pair of middle surfaces (16) each positioned between the outer surface (12) and the inner surface (14). A thickness (Ti) of the inner surface (14) is greater than a thickness (To) of the outer surface (12). A thickness of the inner thick part (28) gradually increases toward the inside. Consequently, the middle surface (16) is inclined with respect to an X direction. A distance (Ld) between an outer end and an inner end in a thickness direction of the middle surface (16) is equal to or greater than 0.5 mm.

A sports product may include a support member and an impact region configured to impact an object. The impact region may be coupled to the support member. The sports product may also include a shear thickening material in at least one of the support member or the impact region. The shear thickening material may be configured to exhibit shear thickening behavior when an impact occurs between the impact region and the object.

A tubular member includes an inner frame portion, an outer frame portion, a wide portion, and a narrow portion. The inner frame portion includes a first inner frame section, a second inner frame section, and an inner connecting section. The outer frame portion includes a first outer frame section, a second outer frame section, and an outer connecting section. The wide portion extends straightly from the outer frame portion to the inner frame portion. The narrow portion interconnects the inner frame portion and the outer frame portion. The narrow portion is arc-shaped, and is spaced apart from the wide portion. A tennis racket includes a racket frame made by bending the tubular member as described previously to define a striking region, and the inner frame portion surrounds and is adjacent to the striking region.

Performance of a racket can be adjusted. A racket includes a grip, an annular frame that is provided with a plurality of through holes that penetrate from an inner circumferential face to an outer circumferential face, and a shaft that connects the grip and the frame in a shaft axis direction, the frame having a rear end side attachment part, on the outer circumferential face of the frame and on a side closer to the shaft in the shaft axis direction, where there is mounted a rear end side attachment to which a string tensely provided to the frame is routed, and the rear end side attachment being made of a material different from the frame.

The present invention relates to a frame for a ball-game racket comprising a head portion and a handle portion, wherein the frame is configured as a hollow profile and comprises magnesium and wherein the wall thickness of the hollow profile varies along a cross-section through the hollow frame profile, as well as to a process for producing such a racket.
