A self-contained laser device is removably affixed on selected golf apparatus, such as a putter. The laser device includes a laser housing having a bore in which a laser module is mounted such that the laser module emits a laser beam through an opening in the bore coincident with the axis of the bore. A switch means is within said bore for activating the laser module. A support member having an upper and a lower portion is provided. The lower portion includes structure for removably affixing and aligning the support member on selected golf apparatus. The upper portion includes structure for removably affixing and aligning the laser housing on the support member such that when the laser device is removably affixed to a selected golf apparatus, the laser beam is emitted in a predetermined optimum direction with respect to the golf apparatus.

This is a continuation-in-part of my U.S. patent application Ser. No. 08/543,442 filed Oct. 16, 1995, now U.S. Pat. No. 5,611,739.
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 survey apparatus which can be used in the underground mining industry comprises a mounting means (11) adapted to be mounted in a fixed surface (such as a tunnel wall) and an alignement means (130, 101) to releasably engage with the mounting means (11), wherein the alignement means (130, 101) is capable of operating only when the alignement means (130, 101) is engaged with the mounting means (11). The mounting means (11) is preferably a sleeve member (11) insertable in a wall. The alignement means (130, 101) preferably has a laser module (102) and a suitable compartment for accomodating a battery (151). The mounting means (11), which is a set aligned in the fixed surface, together with the factory-set alignement means (130, 101) is used for the purpose of setting out and alignements. When the cylindrical shaft (133) is inserted into the sleeve member (11), a rod (170), permanently in contact with spring (154) presses against the screw (158) and makes an electrical connection. As the laser module (102) cannot be switched on when out of the sleeve member (11), battery life is improved and improper use is minimized.
An apparatus and method for teaching golfers proper putting fundementals. The apparatus comprises a device which removably mounts over a putter head, projecting a laser beam on the plane perpendicular to the striking face of a putter just over the sweet spot. The apparatus also includes a means for the golfer to properly align the eyes vertically above the striking face. The laser beam is directed towards and on a linearly calibrated target strip. By directing a shot at various positions on the target strip while viewing the putter from a proper vertically aligned position, a golfer is able to learn to judge putting situations.
A training putter with a laser line projecting device can be used for putting training to improve putting skill. The device is affixed to a putter head above its sweet spot, and emits a vertical light fan which projects a line on the around normal to the face of the putter head. The line is aligned with the sweet spot of the putter head and lies on the ground to connect the top of a golf ball with a target, such as a cup or a putting hole, so that alignment can be easily visualized. The device can be detached and reattached easily without any laser alignment. Furthermore, the device can be removably mounted to a user's own putter. The heat generated in the laser diode is quickly dissipated through the metal housing, the metal putter head, and the metal shaft to the surrounding air. Since proper operating temperature of the laser diode can be maintained, the laser diode will operate properly, which means the power of the emitted light will not be decreased, and the lifetime of the diode will not be shortened.
Golf training apparatus adapted for use with a golf ball and a putter or chipping club having a club head defining a club width includes a U-shaped base having a pair of parallel, substantially rigid side members with a region therebetween which is devoid of base material. A light source, preferably a self-contained, battery operated laser, is mounted with respect to the proximal end portion, preferably at a central location so as to output a light beam proximally to distally along a line substantially parallel to the rigid side members. A momentary contact switch is preferably used to activate the light source. Using such a configuration, the base may be placed on a playing surface and the switch momentarily depressed to illuminate a target with the light beam. By virtue of the open swing region, a ball may then be placed directly on the playing surface before striking in the direction of the target.
