BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to golf, and more particularly to a golf club and practice arrangement that facilitates development of proper club head aiming techniques.
2. Description of the Background of the Invention
One element of a proper golf shot is proper orientation or aim of the club head. It is important that the club head be properly oriented relative to the golf ball and to the target during set-up of the golf shot. A proper golf swing or stroke will return the club head to the golf ball at substantially the same orientation and alignment adopted by the player during set-up. Thus, when addressing the golf ball, it is important the club head be properly oriented and aimed relative to a primary target along the desired line of ball flight or roll.
The most-used club in golf is the putter. The most important and difficult task to accomplish with a putter is proper aim. To achieve proper alignment and orientation, one typically practices, without outside aid, until a proper golf swing is achieved, through a process of trial and error. Such a process is time-consuming, and with modern technologies, can be aided with the help of practice arrangements which can facilitate development of proper putting techniques.
SUMMARY OF THE INVENTIONIn one embodiment, the present invention facilitates the development and practice of proper putter aim, one of the fundamentals in putting and one of the most difficult to master.
In certain embodiments, the present invention is intended primarily as a practice device which may be used both indoors and out. However, the golf club of the present invention may also be used in actual play on a course. This is desirable in that it eliminates the need to transfer learning from a practice device to an alternate club used in regulation play.
In certain embodiments, the practice arrangement and golf club of the present invention is well-suited for both purposes—practice and regulation play—and may be used both to learn proper aim and alignment of the golf club, as well as to actually play the game of golf.
In one embodiment, the present invention includes a golf club with a shaft, a head attached to the shaft, a light-producing insert, and a non-light-producing insert. The head has a ball-striking surface, an aperture formed in the ball-striking surface for allowing light to pass therethrough and a cavity formed in the head adjacent the aperture. The light-producing insert is configured so as to be operably and removably received within the cavity. The non-light-producing insert is configured so as to be selectively received within the cavity in place of the light-producing insert.
In one embodiment, the non-light-producing insert is substantially equal in weight to the light-producing insert and, in certain embodiments, may be substantially the same size and weight, and have substantially the same weight distribution, as the light-producing insert.
In certain embodiments, the ball-striking surface of the head has a translucent material disposed over the aperture. A prism, or lens, may be disposed in, or behind, the aperture for transmitting light produced by the light-producing insert. The prism columnates a light beam produced by the light-producing insert such that the light beam forms a line on a surface between the head and a target. In addition to forming a line on a surface, a portion of the light beam may be projected onto a surface of a target.
In certain embodiments, the prism may be formed as part of the light-producing insert. In these or other embodiments, the aperture is located in an approximate midpoint of the ball-striking surface. A switch may be provided to allow a user to selectively activate the light-producing insert.
In one embodiment, the light-producing insert can include a battery-powered laser device. The non-light-producing insert may be formed of any material having an appropriate size, weight and weight distribution.
In one embodiment, the invention includes a practice arrangement, which includes a combination of a golf club and a target. The golf club includes a shaft, a head attached to the shaft, a light-producing insert, and a non-light-producing insert. The head has a ball-striking surface, an aperture formed in the surface allowing light to pass therethrough and a cavity formed in the head adjacent the aperture. The light-producing insert is configured so as to be operably and removably received within the cavity. The non-light-producing insert is configured so as to be selectively received within the cavity in place of the light-producing insert.
The target has both a surface for reflecting and a surface for receiving at least a portion of a light beam produced by the light-producing insert to provide an indication of the orientation of the head relative to the target. The target may have a surface which extends transversely to a target line defined by the light-producing insert. The surface may have a plurality of regularly-shaped marks thereon. A portion of the target may be configured so as to extend into a golf hole, or cup, to secure the target in position relative to the hole.
The concepts disclosed are not limited to use with a golf club of the exact type illustrated in the drawings, but may be used with golf clubs of many shapes, sizes or dimensions. Additional embodiments, features and advantages will become apparent to those of skill in the relevant arts upon consideration of the following description of the illustrated embodiments exemplifying the best mode of carrying out the invention.
