An endcap system for a sporting implement includes a base portion and a transverse extension projecting from the base portion. The base portion has a bottom surface with a central axis normal thereto. A receptacle opposite the bottom surface is configured to receive a portion of the sporting implement. The extension is configured such that, during swinging of the sporting implement with a hand of a user gripping around the sporting implement portion, the extension contacts an exterior lateral portion and upper portion of a fifth metacarpal of the hand and the hand is constrained in both the transverse and longitudinal aspects while being allowed rotation of a first metacarpal of the hand away from the central axis.

An improved anchor fitting (10) for anchoring a tether cord (22) to a hollow ball (12). The anchor fitting (10) includes an anchor body (16) comprising a shank portion (18) and a head (20) at one end of the shank portion. The anchor body is received in a hole (14) in the wall of the ball and defines an axial passage through which the tether cord extends. The anchor fitting includes two rigid shoulder-defining bodies (26) and (28) which are located within the ball and which extend perpendicularly relative to one another when assembled. The shoulder-defining bodies define holes in which the shank portion of the anchor body is received, with the head (20) abutting an inner side of the shoulder-defining body (28). A flexible resilient rubber washer (34) is located between the shoulder-defining bodies and an interior side of the wall for absorption of impact forces acting on the wall of the ball when the ball is struck by a bat.

The present invention discloses a system 200 and an apparatus 100 for throwing a sports object 102 includes a body 110 with a feeding point 120 and a releasing point 130. A plurality of passages 112 structured in body 110 to extend from the feeding point to the releasing point 130. The one or more rotating means 114 are positioned in the body 110 such that a rotating surface 116 of the rotating means 114 extends into at least two passages 112 away from each other, wherein the rotating means 114 is adapted for throwing the object 102 received from the feeding point 120 to the releasing point 130 away from the apparatus 100 in one or more direction to achieve desired object delivery from the releasing point 130.

The disclosure provides a badminton net rack, comprising a base, has an grounding side and a mounting side opposite to each other, the base comprises two seat bodies, a support rod connecting the two seat bodies, and a connector spanning the support rod, the connector comprises a first stuck part and a second stuck part, the first stuck part is used for stuck badminton racket; two telescopic rods, can be switched between an inverted trapezoidal state and a stuck state, in the inverted trapezoidal state, the two telescopic rods are respectively connected to the two seat bodies to form an inverted trapezoidal structure for installing a ball net, in the stuck state, the two telescopic rods are respectively stuck to the two second stuck parts of the connector. The above-mentioned badminton net rack has various functions, is more portable and has better stability.

The present invention relates to a ball game racket with strings that comprise at least one string comprising a superelastic material.

The present disclosure relates to a method for measuring a speed of a sports device. The method includes: acquiring movement data of the sports device during a process of tracking the sports device, the movement data being collected by a sensor disposed at a bottom of the sports device; calculating a linear speed and a rotational speed of the sports device based on accelerations of three axes in the movement data; and combining the linear speed and the rotational speed to obtain a movement speed of the sports device. In addition, the present disclosure also provides an apparatus for measuring a speed of a sports device, which corresponds to the above method. The method and the apparatus for measuring a speed of a sports device can improve the credibility of the speed measurement of the sports device.

The current invention aims at improving the playability, durability, and spin generation of different playing rackets, as tennis, squash, and badminton rackets. The method to do so is by applying mechanical forces which generate relative motion of the latitudinal strings over the longitudinal strings. This is done in order to create friction that generate depressions in the contact points of the latitudinal strings with the longitudinal strings. These depressions, made by the described method and machine, induce more friction, and generate spin, while increasing the playability and durability during the play.

The scorekeeping system includes a plurality of scoring elements. An upper bracket can be secured a first string having a first portion of the plurality scoring elements and a second string having a second portion of the plurality of scoring elements. The first string can have a first thread and a second thread, each of the first thread and the second thread being threaded through the first portion of the plurality of the scoring elements. The second string can have a third thread and a fourth thread, each of the third thread and fourth thread being threaded through the second portion of the plurality of the scoring elements.

A ball (100) for use in bat and ball games wherein the ball is struck with a bat having an untensioned, rigid ball-striking surface, includes a hollow spherical impact body (112) having a mass of between 10 g and 50 g which enables the use of lightweight bats. The wall of the impact body is of a resiliently compressible material and defines a convexly curved impact zone IB. The ball further includes a flight control assembly (114) including a tail (50) comprising flexible streamers (52), a spacer stem (54) and an anchor fitting (126) for anchoring the spacer stem to the impact body. The configuration of the impact body is such that the impact zone compresses to a minimum compression depth of 12 mm and the impact body bounces to a height of at least 100 cm when the impact body is subjected to a drop test wherein the impact body is dropped onto a test impact surface.
