Abstract:
Disclosed is a tennis racket (1) including an oval frame (10) supporting a mesh (14). The little holes or all the little holes (140) of the mesh (14) are arranged between the geometric centre (C) of the frame and the apex (S) of the frame.
Abstract:
A solution is provided to enhance motion detection and recognition of moving objects associated with various sports by embedding motion sensors into sports instruments such as tennis rackets, badminton rackets, baseball bats and golf clubs, that are swung in a three-dimensional (3D) space. A motion sensor device inserted and locked inside a sports instrument is configured to detect motions associated with movements associated with the sports instrument. The device is shaped to be inserted into a sensor housing attached to a selected location inside the sports instrument. The device includes a motion sensor for detecting motion associated with the movement of the sports instrument, a cover for protecting the motion sensor, and a locking mechanism attached to the sensor housing for locking the motion sensor inside the sensor housing.
Abstract:
The present invention provides a game racquet including an integrated circuit capable of supporting a low-voltage energy current. An embodiment of the invention provides a game racquet including one or more enhancements attached or integrated on the racquet frame. These enhancements may include but are not limited to: one or more LEDs, a sound amplification device, an electromagnetic vibration emitter, and other such enhancements as would be apparent to one skilled in the art. In a further embodiment, the game racquet responds electronically to ball impact on at least one of the strings, and subsequently performs and action or actions including but not limited to making a sound or sounds, triggering lights, triggering LEDs, triggering another type of automation on the racquet such as a vibration emitter within the handle.
Abstract:
A device and method for determining a distance from the device to a distant point is disclosed herein. The device includes a GPS component, a laser component, a camera component, a memory, a display component, a user input, and a processor comprising means for determining a distance between any two points.
Abstract:
The netting structure of a fiber-made racket comprises a racket frame and several supporting parts. The racket frame is formed with upper and lower racket frames made of the fibrous material, and internal and external penetration netting areas are formed around between the upper and lower racket frames. Several supporting parts are provided in the netting area, a couple of parts adjacent to each other are lengthways stationary in the netting area of racket, and the threads of the racket pass through the couple of supporting parts and cross vertically and horizontally in the racket frame to form a hit area. Thanks to the interval of distance of thread passing between the netting area and the supporting parts, it is easy and fast to pass the threads, reducing the area of net threads contacting with the racket frames to increase the flexibility of hit area at the time of hitting.
Abstract:
The present invention is intended for use as a game racket including a handle and a head frame with strings held in tension. In particular as a high performance game racket frame including at least one generally tubular, substantially circular pivot element located at least partially within a substantially circular mating recess on at least one portion of an outside-facing peripheral surface of the head frame profile that can rotate to cooperate with at least one string. The pivot element can rest upon at least a portion of the mating recess and therefore can have at least one adjoining surface portion. In order to reduce friction, adjoining surface(s) can be coated with a suitable anti-friction agent such as silicone or it can include a “frictionless” repelling permanent magnet portion capable of sustaining magnetic levitation between the two parts. Alternatively, at least a portion of the adjoining surfaces can include communicating electromagnetic friction plates in order to control the rate at which the pivot element rotates.
Abstract:
A racket includes a handle, a frame connected to the handle and having a longitudinal axis extending from and aligned with the handle, and a stringed web supported on the frame. The frame has two ends that are opposite to each other along the longitudinal axis. The stringed web is formed by a plurality of intersecting longitudinal strings and transversal strings defining a plurality of meshes. The longitudinal strings and the transversal strings together further define a primary ball-striking portion on a substantially central portion of the stringed web, and the meshes located in the primary ball-striking portion gradually increase in size in a direction from one of the two ends to the other one of the two ends of the frame.
Abstract:
Devices for determining the string tension of racket strings are provided. In some embodiments, devices for determining the string tension of racket strings comprise: a body having a front surface indicating different combinations of player and racket characteristics, windows corresponding to certain types of rackets, and an axis perpendicular to the front surface; and a rotary disc which is rotateably situated on the axis behind the front surface and which has numbers indicated thereon representing racket string tension values that can be viewed through the windows for the different combinations of player and racket characteristics.
Abstract:
A sports racquet having a plurality of string port holes and conventional string holes is formed of a single tube of prepreg material. When molded, mold elements press opposed portions of the prepreg tube into contact with one another, and shape the adjoining prepreg material into a string port hole blanks. The portion of the pressed-together material which initially blocks the string port hole is removed after molding so that the string port holes extend through the frame. Alternatively, the mold elements cause the prepreg tube to follow a serpentine shape, thereby defining string port holes which are open alternately along the top and bottom surface of the frame. A pair of cover rings may be secured to the top and bottom racquet surfaces to cover the open sides of the string port holes.
Abstract:
In a sports racquet, anchor points for a string are marked with indicia to assist a stringer in stringing from one anchor point to a next anchor point. In a preferred embodiment, one of the anchor points is a bearing assembly located within a hollow cavity in the racquet stem. Colored tubes are placed in the stem that lead to and from the bearing assembly, and the colors of the tubes match respective colored indicia associated with string holes in the frame head.
