Abstract:
1. Golf putter apparatus comprising, in combination: a golf putter including a shaft, a head connected to said shaft and a handle at an upper end of said shaft, said head having a golf ball engagement surface extending relative to said shaft in a lateral direction, and said shaft having an inner surface defining a shaft interior and an elongated aperture communicating with the shaft interior, spaced from said head and said upper end and extending longitudinally along a portion of said shaft; a laser light generator in said shaft interior for generating a downwardly directed laser light beam in said shaft interior; a mirror having a reflective first surface in said shaft interior next to said elongated aperture and positioned to receive the laser light beam from said laser light generator and reflect said laser light beam through said elongated aperture and outwardly and downwardly therefrom to a location on the ground spaced forwardly of said head; mirror mounting structure within said shaft interior, said mirror mounting structure of unitary construction and elongated configuration and forming an axially extending passageway permitting passage of the laser light beam from said laser light generator to said mirror, said mirror mounting structure including a plurality of spaced, outwardly extending stabilizing members frictionally engaging the said shaft at lengthwise spaced locations of said shaft, one of said stabilizing members projecting into said elongated aperture to maintain the mirror mounting structure in said shaft interior and in a stable fixed position and orientation relative to said shaft; and a manually movable actuator rotatably connected to said mirror mounting structure by cooperating indents and detents thereon for selectively tilting said mirror to position said mirror in alternative angles of inclination, and the mirror operable to reflect laser light from said laser light generator through said elongated aperture forwardly of said golf ball engagement surface in any of said alternative angles of inclination, said manually movable actuator having a first outer peripheral segment disposed within said axially extending passageway having said mirror affixed thereto with the reflective first surface thereof closely adjacent to and facing said elongated aperture, said shaft defining a slot at a shaft location opposed to the location of said elongated aperture, and said manually movable actuator projecting through said slot and having a manually engageable second outer peripheral segment disposed externally of said shaft to allow selective manual rotation of said manually movable actuator to change the inclination of said mirror, said mirror mounting structure additionally including a receptacle supporting said laser light generator with said laser light generator firmly held within the receptacle to prevent relative movement between said laser light generator and said mirror mounting structure with the laser light generator pointed toward said mirror and laser light from the laser light generator passing through the axially extending passageway of said mirror mounting structure.
