A golf swing training device includes an aerodynamically shaped housing which may be attached by a suction cup to the upper surface of a golf club, preferably a wood because of the larger upper surface area. The housing contains a pair of batteries for selectively illuminating a light source, preferably a red LED, protruding from the top of the housing. The illuminated light source creates a visual "track" of light as the as the club is swung and helps the golfer visualize the path of the club head and the swing plane.
A golf club head and laser pointer arrangement, which includes a golf club head, the golf club head having a recessed chamber and an elongated slot on a face thereof in communication with the recessed chamber, and a laser pointer mounted in the recessed chamber, the laser pointer having a laser firing hole, a lens mounted in the laser firing hole, and a laser diode and driver circuit controlled to emit a laser beam through the lens and the elongated slot on the face of the golf club head for pointing the ball toward the target hole in a golf course.
A golf club with a laser sight includes a shaft having a lower end provided with a club head, a metal tubular portion provided on a top of the club head, a laser generator fitted within the tubular portion and provided with a first electrode at a cylindrical surface thereof and a second electrode at an end thereof, a conductive spring connected with the second electrode of the laser generator, a tubular insulator fitted within the tubular portion, a plurality of batteries connected in series and fitted within the tubular insulator, a cover threadedly engaged with the tubular portion and having a center hole, a circular insulator arranged between the batteries and the cover, an adjust screw threadedly engaged with the center hole of the cover and having an inner end provided with a projection, whereby when the adjust screw is turned into the cover to contact an electrode of the batteries, a closed will be formed thereby providing power to the laser generator and therefore causing the laser generator to emit a laser beam, and when the adjust screw is turned out of the cover, the circuit will be opened thereby turning off the laser generator.
A golf training device includes a golf club, a ball receiving socket, a light emitter, and a light beam receiver. The golf club includes a golf head with a front striking face. The golf ball receiving socket has a slot adapted to receive a golf ball that was struck by the golf head. The light emitter is mounted on the golf head and is aligned vertically with the center of the front striking face for emitting a light beam substantially parallel to a line passing through the center of the front striking face and perpendicular to the front striking face. The light beam receiver is mounted on the ball receiving socket in the vicinity of the slot for receiving the light beam and for generating a signal when the slot is in alignment with the light beam.
A golf club for showing swing condition has a shaft and a head connecting to the shaft, and the head having a striking face. The golf club has a visible illuminant that is mounted on the head and exposed outside the head with an upward angle. A battery is for providing electrical power to the light. A centrifugal switch that is actuated by centrifugal force is mounted on the head opposite the striking face for controlling a circuit between the battery and the illuminant. Thereby the illuminant will light by a predetermined-strength centrifugal force during swinging the golf club for investigating the body harmony and strength-exerting condition of golfer.
A customizable alignment sighting device for a golf club is mounted to an upper surface of the head of the golf club with a sighting element providing the user a visual target indicator for desired alignment of the club head with the user's line of sight. The sighting element can be readily adjusted for the user's preferences. When not aligned, the sighting element provides an indication of the magnitude and direction of misalignment. In one embodiment, the device is shaped as a planar disc mounted on the upper surface of the club head by leveling posts spaced around its periphery. The sighting element is a concave lens or lenticulated grid or grill superimposed on a target image. In another embodiment, the device has a 3D device body mounted in a mounting cup or socket fastened to or formed in the head of the golf club. The device body has a larger-diameter circle marked around an annular opening, and a smaller-diameter circle marked depthwise inside the opening in the device body to provide a target of concentric circles by parallax effect. The device body can be formed as a sphere with axially split sides that are expanded outward when an expansion plug is threaded in the bottom, providing an interference fit holding it in position in the mounting cup. The spherical body can be formed with 4 alignment sighting holes at 90.degree. intervals around a vertical plane and provided with a weighting element fixed at an offset position, such that it can be rotated to use any of the different alignment holes for adjusting the weight distribution in the club head.
