Abstract: A lineman trainer includes a base on which are mounted three receiving brackets. Pads are mounted over these brackets. Each of the brackets is mounted on a mechanism that allows the brackets to move. An actuator mechanism may be manipulated by a coach or other operator to activate the brackets independently of one another. When the actuator is reciprocated in one direction or another, it releases one or the other of the side brackets so that a spring can pivot the brackets toward the lineman. When the actuator is rotated so that its handle travels downwardly, the central bracket is released and springs push it directly outwardly toward the lineman. When a lineman hits a released bracket, it is moved back to the locked position ready for another movement when actuated by the coach or other operator.

Abstract: This invention is for someone who wants to exercise, self-teach or teach the golf swing. The object is to make contact with the “sweet spot” portion center of the club head. Using this will tone the rhythm of his or her body to a consistent swing posture. The results will lead to straighter, longer drives. This unit can be used as a warm up prior to the golf course or driving range. What helps make this a reality is the ball will project a material that will leave a mark on the club head, indicating the area of impact. This will be wiped away before each swing. The user can adjust standing spot or hands or what they feel was the reason for not making contact in the sweet spot. Once you show a person how to hold the club, they can swing at this flowable ball and your lesson to them has begun. When they can become somewhat consistent at making contact, going to the driving range is there next step. After someone takes a lesson, they may want this invention to use at home to practice.

Abstract: A golf training device to help maintain the proper synchronous relationship between the movement of hands and hip rotation during a golf swing. In the event that the movement of the hands and hip rotation of the user are out of synchronization, the training device provides feedback to the user. The training aid device basically comprises a strap that secure a sheet to the rearward leg of the user. A trapezoid shaped panel is mounted to the sheet, which provides the user with a reference as to the proper positioning of a user's hands and the shaft of the golf club during address, and which provides a tactile feedback signal to the user, if the user's backswing is improper or if the user's hip rotation and movement of the user's hands are out of synchronization, by making contact with at least one of the user's hands.

Such a golf ball is constituted of a core and a cover and the cover has a loss tangent of 0.15 to 0.70 at −10° C. in a temperature distribution curve for dynamic viscoelasticity measured in a tensile mode under conditions of temperature increasing rate of 4° C./min, frequency of 10 Hz and initial strain of 1.0 mm.

Abstract: A golf ball includes at least a core, an inner cover, and an outer cover. The inner and outer covers are of different colors. A portion of the inner cover penetrates the outer cover and is exposed to the outside on the surface of the golf ball. The exposed portion constitutes a mark portion on the surface of the golf ball. Further, an auxiliary layer is provided in contact with the inner cover. The auxiliary layer has a color different from those of the inner and outer covers and has an end surface which is exposed to the outside on the surface of the golf ball within the mark portion. Either the inner cover or the auxiliary layer completely covers the core.

Abstract: The golf ball comprises all known cores provided with a cover produced by a polymer blend that combines the durability of a conventional cover with the feel of a traditional balata cover having a plurality of dimples in a modified dodecahedron pattern. The dodecahedron consists of twelve pentagons, which are subdivided into a total of sixty triangles. The triangles are then further subdivided into rows into which various diameter dimples are placed. The dimple pattern can be arranged to produce a pattern of ten great circles, which are free of dimples. The cover formulation is a blend of various ethylene/methacrylic acid copolymers wherein at least one copolymer has a high modulus and at least one copolymer has a moderate modulus forming a miscible blend having a PDI index that maximizes durability while still maintaining feel and playability.

Abstract: A golf ball includes an outer land surface and a plurality of dimples formed thereon. The dimples comprise structures of its surface to energize or agitate the airflow over the dimpled surfaces to increase the aerodynamic performance of the golf ball. These structures may include sub-dimples arranged in various configurations on the dimple. The sub-dimples may have various sizes and shapes. The structures may also include radiating concave or convex arms emanating from the center or a location proximate the center of the dimple. The radiating arms may have various sizes and shapes and may protrude beyond the dimples. By improving the aerodynamic of the airflow over the dimpled surface of the golf ball, the outer land surface of the golf ball may remain robust to prevent premature wear and tear on the golf ball.
