The present invention is directed to a racquet design with an inner and outer frame connected by an isolation system. Uniquely adapted to tennis racquets, the natural motion of the inner frame relative to the outer frame upon impact of the tennis ball on the inner frame will generate spin when the ball contacts the inner frame. The relationship between the inner frame, outer frame and isolation system can control the spin imparted to the ball for a given tennis swing. The tuning of the isolators relative to conventional racquet characteristics will increase the amount of ball spin caused by conventional racquets. The invention also increases the accuracy of the tennis ball's trajectory.

Disclosed is a tennis racket including: an oval frame adapted to support a latticework, and through-bands for the the strands of latticework cord, each band being received in an outer housing in the frame and including through-tubes for the strands, the tubes being inserted in the direction of the interior of the frame in through-holes provided in the frame. Each band is arranged flush with the outer edge of the cross-section of the frame, and an outer shell of the cross-section of the frame is essentially diamond shaped.

This is an improvement or change in tennis racket's strings position from the middle of the racket frame to the side of the tennis racket frame. An improvement in tennis racket to allow the player to create more and faster ball spins and to reduce errors in the game. A tennis racket with strings on both the sides of the frame, or only on one side of the tennis racket frame is my invention.

If not acceptable to the tennis authorities or player, a tennis racket frame with cross section diamond shape to allow the manufacturer to make the smallest possible size of tennis racket frame, so that players can create more and faster ball spins and reduce errors in their games.

A tennis ball retrieval apparatus with enhanced ball retention capability coupled to a frame of a tennis racket is provided. The tennis ball retrieval apparatus includes a scoop assembly with an upper receptacle coupled to a base member, the base member having a generally U-shaped member coupled to the frame of the tennis racket, the upper receptacle having a generally spherical scoop with a front opening and an inner concave surface designed to conform to contours of the tennis ball. The tennis racket is maneuvered in a sweeping motion to permit the generally spherical scoop of the upper receptacle to scoop the tennis ball through the front opening. This permits the inner concave surface of the upper receptacle to conform to the tennis ball, thereby permitting the upper receptacle to retain the tennis ball therein.

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.

A racket including: a grip; an annular frame provided with a plurality of through holes extending through from an inner peripheral face to an outer peripheral face; a shaft connecting the grip and the frame; and a grommet to be attached to the outer peripheral face of the frame, the grommet including: a plurality of tube sections to be inserted into each of the plurality of through holes provided to the frame; and a base section that connects the plurality of tube sections to one another, the tube sections each including a communicating hole that communicates a base section side opening on the base section side with a tip end side opening on the side to be inserted through the through hole, the tip end side openings of at least some number of the tube sections, of the plurality of tube sections through which a string to be strung in a direction along a longitudinal direction of the racket is inserted, being wider than the base section side openings in a direction in which the plurality of tube sections is arranged.

Provided herein are racquets, such as sports racquets. The racquets generally comprise a head frame with a curved side portion and a straight top portion and a curved bottom portion and handle affixed to the head frame between the top portion and portion. A plurality of openings is equally spaced through the head frame and a portion of the handle and a plurality of strings comprising a net pass through the openings. The length of the top rim of the head frame is greater than the bottom rim. The handle connects to the head frame at an angle of about 140 to 150.

A racket may include a frame including at least one prepreg layer. The at least one prepreg layer may include reinforcing fibers. The at least one prepreg layer may also include a matrix at least partially surrounding the reinforcing fibers. The at least one prepreg layer may also include graphene material.
