Abstract: A racket frame has a head hoop, a connecting segment, at least two through holes and a handle. The head hoop has a bottom end and a string. The connecting segment is connected with the bottom end of the head hoop and has a yoke, two shafts and a throat. The yoke is formed on the bottom end of the head hoop. The shafts are respectively mounted with the yoke and each shaft has an upper end, a lower end and two sidewalls. The throat is connected to the lower ends of the shafts. The at least two through holes are formed respectively and symmetrically through the sidewalls of the head hoop or the sidewalls of the shaft between the upper end and the lower end. The handle is connected with the connecting segment and has a proximal end.

Abstract: A racket frame has a head hoop, a connecting segment, a handle and two prestressing devices. The head hoop has a bottom end and a string. The connecting segment is connected with the head hoop and has a yoke, two shafts and a throat. The yoke is formed on the bottom end of the head hoop. The shafts are respectively mounted with the yoke and each shaft has a mounting hole. The handle is connected with the connecting segment. The prestressing devices are attached to the shafts in the mounting holes.

Abstract: A racket frame has a handle, a connecting segment and a frame. The connecting segment is inverted triangle shaped, is connected with the handle and has a throat and two shafts. The throat is connected with the proximal end of the handle. The shafts are respectively formed with the throat. The frame is hollow, is elliptical shaped, is made of aluminum alloy, is connected with the connecting segment and has a frame segment and at least one compound material tube. The frame segment has a yoke, a bottom segment and a string. The at least one compound material tube is made of carbon fiber, is attached to the bottom segment and each has a proximal end and a distal end.

Abstract: A racket frame has a head frame, a triangular neck, and a handle. The head frame is oval-shaped and has a bottom end, and an arc opening defined at the bottom end of the head frame. The triangular neck is attached to the bottom end of the head frame and has a bridge and two arms. The bridge is made of fiber carbon composite and received inside the arc opening of the head frame. The two arms respectively attach to two distal ends of the bridge and further extend to abut the head frame. The handle is made of carbon composite and attaches to the triangular neck. By selectively using carbon fiber composite at the bridge and the handle, weight of the racket frame is minimized, durability of the racket is high and material cost of the racket frame is acceptable.

Abstract: An aluminum tennis racket includes a head, a shaft and a handle. The head and the shaft are made of hollow aluminum tubing with a series of ripples. The ripples are defined on a sidewall of the hollow aluminum tubing, and the ripples increase the strength of the head and the shaft so the sidewall is lighter and thinner. The lighter tennis racket helps a player to quick react, and the increased strength allows the player to strike a ball powerfully.

Abstract: A racket is composed of multiple sections of tubes made of different material with resilient material bonded between the tubes at the joints to attenuate vibration and shock and thus make striking a ball more comfortable for a player.

Abstract: A shock-absorbing racket body is comprised of the conventional body elements including an elliptical frame, a Y-shaped throat, a shaft and a handle and at least one slit defined one or a combination of the conventional body elements to receive a shock-absorbing device to absorb the reactive force generated when striking a ball. The absorbing device is provided to absorb the reactive force when striking a ball and to damp and attenuate resonant vibration after striking a ball to prevent injury to the player's wrist.

Abstract: A sport racket includes a neck and a handle. The neck has an outer tapered wall provided with an outer bottom formed with the outer tapered wall; and an inner tapered wall provided with an inner bottom formed with the inner tapered wall. The handle has a tapered wall defining an open chamber to receive the outer bottom of the neck; an elastomer securely abutting a bottom defining the chamber; and a threaded bolt extending through the inner bottom, the outer bottom, the bottom of the chamber and the elastomer to screw into a nut.

Abstract: A method of making a metal racket including wrapping around a foamable material a shell of composite material, splitting each end of the shell so that two pieces are formed on each end of the shell, attaching the pieces of the shell to the throat portion of the racket, wrapping around the pieces of the shell and the throat portion with an outer layer which is made of composite material, hot-pressing the racket and the shell in order to foam the foamable material and in order to cure the shell so that the shell can be formed integral with the racket as a yoke of the racket.
