CA 02300735 2000-02-25 ,.-The Multiple Adjusting Angle Bracket The laser generator unit: The laser generator unit is self contained-inclusive of power supply, activating switch and mounting; interface. The laser generator unit incorporates a semi reflective lens to A first beam of 25% intensity adjustably projects near linear to the shaft and forward of the clubface to contact the ball or the ground at a point perpendicular to the sweet spot on the clubface. A second ~reflecte~d beam of 75% intensity projects angular to the club shaft and contacts the intended target or ground at a point perpendicular to the clubface. The second and reflected beam is affixed at 4.5 feet in lead of the clubface. The removable laser generating unit projects forward of the club relative to the direction of swing. This postioning is visible less obstructive. Secondly, this arrangement allows for use of the laser generating unit on left-handed or right-handed clubs with no modifications to the appliance.
Laser light emitting diode: The laser light emitting diode is a compact, lightweight, and low-cost visible light source that has adequ;~te intensity and does not defuse in daylight. The energy beam created by the laser light emitting; diode is split into two trajectories of prescribed intensities. The first beam is directed out the bottom of the unit housing after passing through the semi reflective mirror. The first beam travels in a line fifteen degrees angular to the plane of the mounting interface: The first beam creates an illuminated dot 6 inches ahead of the clubface and perpendicular the sweet spot or idf;al point of contact with the ball.
Seventy-five percent of energy from the laser light emitting diode is redirected as it passes through the semi transparent mirror. The second energy beam is strong enough to remain visible at a distance of twelve feet (720cm.) in direct sunlight conditions. The semi reflective mirror is mounted to the unit housing in linE; with the energy beam. The angle of contact that the energy beams make with semi reflective surface is 15 degrees. The forward angular light beam moves towards the intended target as the golfer strokes the hall. Duxing the backstroke the (rear) light beam passes over the ball to ensure the golfer makes a pendulum swing needed for a straight putt.
As the rear beam is moved behind the ball on the b;ackstrolce, the forward beam has now moved down the perpendicular plane to replace the rear beam thus both beams work together to ensure a perpendicular swing and straight follow through towards the intended target.
Your swing path can now be easily adjusted as tile two energy beams show the exact path the ball will follow when it is stroked.
Semi reflective mirror: The sf;mi reflective mirror is used to split a single laser light source into t~NO separate energy beams. of different intensities. The energy beam is directed at the semi reflective mirror. Twenty-five percent of the energy beam passes through the medium unobstructed while seventy-five percent of the energy is reflected to produce a second beam directed angular to the first. The first beam of twenty-five percent intensity is strong enough to be visible near the clubface in direct sunlight conditions. The second and reflected beam of seventy-five percent intensity is strong; enough to remain visible at a distance of twelve feet (720cm.) in direct sunlight conditions. The angle of contact that the energy beam makes with the semi reflective surface of the mirror is affixed at fifteen degrees. The mirror affixed at fifteen degrees, is positioned to teach the golfer consistency. As he works with each club, the energy beams act as a visual aid to assist the golfer to repeat the perfect swing. As he becomes more consistent by seeing his swing path, his muscle memory is enhanced and his game significantly improves.
Power supply: The power supply includes a series of electronic components that generate electric energy in a usable form for the. laser light emitting diode to produce an effective visible light beam. A small battery pill; of higlh energy density such as those used in the camera industry is used. Solid-state electronic components modify the do current produced by the battery pile. A latching toggle switch is located externally on the unit housing to function as an ON/OFF switch.
Activating switch: A latching toggle switch is located externally on the unit housing to function as an ON/OFF switch. This switch is conveniently located so that the golfer can easily turn an or off the device while mounting or removing it from the desired club.

The I'vlultiple Adjusting Angle Bracket: The detachable laser generator unit is easily detachable from the multiple adjusting angle bracket without the use of any tools. The bracket is formed in two pieces that are placed around the club shaft near to the handle.
Each piece of the multiple adjusting mounting bracket is provided with a semi-circular channel for the club shaft to occ;upy. The semi-circular channel is tapered to match the taper of a standard or average club shaft, the lower end being morf; slender. The channel can be made smaller as required by using sleevE;s or reducers bushings to match the diameters of smaller club shafts.
The multiple adjusting angle bracket is secured around the club shaft with fastening screws that pass through holes provided in one piece while threading into the second half to provide compression upon the club shaft. Exact height along the club shaft is determined by adjusting the first laser beam to focus on a point six inches forward of the clubface and beam to focus on a point four and a half feet in lead of the clubface. The mmltiple adjusting mounting bracket can also be rotated axially about the club shaft to perform adjustments of the beam prior to tightening the mounting screws. A third means of adjustment is provided at the mounting interface between the detachable laser generating unit and the multiple adjusting mounting bracket.
The detachable laser ;generating unit can be displaced ;angular relative to the club shaft along the plane descriibed by the mounting interface. T'he adjustment is performed by changing the relation betwE;en the laser generating unit and detachable member that mates with the multiple adjusting mounting bracket. The detachable member is pivotally secured to the laser generating unit with a fastener. A second fastener passes through a slot in the detachable member and threads securely into the laser generating unit )housing. The slot is long enough to allow required angular displacement of the laser generating unit to provide useful adjustment in both left-handed and right-handed swim; applications. This adjustment is performed in several steps:
remo~~ing the detachable laser l;enerating unit from the multiple adjusting bracket, loosening the fastener that intersects the slotted hole to a point where rotation of the detachable member is possible with substantial resistance, re~,placing the laser generating unit, aligning the laser beams as de sired, removing again the laser generating unit and securely tighten the fastener. The plane described by the mounting interface is linear to the axis of the club shaft.
The plane described by thf; mounting interface is aligned parallel to the clubface so that the removable laser generating unit projects forward of the club relative to the direction of swing. This positioning is visibly less obstructive. Secondly, this arrangement allows for use of the laser generating unit on left-handed or right-handed clubs with no modifications to the appliance.
The detachable member of the laser generating unit ha.s grooves that interlock with meshing grooves affixed to the multiple adjusting angle bracket. T'he laser generating unit easily locks into place with accurate and repeatable alignment. The laser generating unit is easily removed from the club and stored between holes, rounds, or games. The laser generating unit is compact enough to fit into tlhe golfer's pocket. The golf club is slender enough to fit into a regular golf bag with the multiple adjusting bracket affi~;ed. ThE; multiple adjusting bracket is smooth and angular enough to slide unobstructed off other clubs and obstacles without being hindered.
