Abstract
Abstract Golf practicing apparatus characterized in the use of adjacent strips of luminescent or light-emitting material on the upper surface of a golf club in a manner such that when the club is swung through an arc, a visible trace pattern is emitted by the luminescent or light-emitting material which enables an observer to make a rapid and accurate determination as to the disposition of the golf club head throughout its arcuate path of travel. The pattern comprises three adjacent stripes of outer black stripes and an intermediate stripe of red. Luminescent reference guide stripes in the path of travel of the club are also provided one of which stripes is tangential to the path of travel of the club and the other of which guide stripes is perpendicular thereto and at a point of impact of a golf ball. Another form of the invention includes stripes of a luminescent chemical that are covered with a cover that is ruptured prior to use so that airborne oxygen reacts with the chemical to yield a distinctively colored light pattern when the club is swung through an arc.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
139 words
In the combination of a golf club having a shaft with a head at the lower end thereof, a striking surface at the forward end of said shaft and luminescent means associated with said head of said golf club for permitting visual observation of the movement of said club head during the execution of a swing of said golf club, the improvement comprising: said luminescent means including a plurality of nonspaced adjacent stripes of luminescent material disposed on the uppermost surface of said club head with the forwardmost ends of said stripes being substantially perpendicular to a vertical plane containing at least the uppermost edge of said striking surface, whereby when the golf club is swung at an improper angle the nonspaced adjacent stripes merge and form visible diagonal lines across the movement of travel of the club head.
Claim 2
Dependent Claim
139 words
In the combination of a golf club having a shaft with a head at the lower end thereof, a striking surface at the forward end of said shaft and luminescent means associated with said head of said golf club for permitting visual observation of the movement of said club head during the execution of a swing of said golf club, the improvement comprising: said luminescent means including a plurality of nonspaced adjacent stripes of luminescent material disposed on the uppermost surface of said club head with the forwardmost ends of said stripes being substantially perpendicular to a vertical plane containing at least the uppermost edge of said striking surface, whereby when the golf club is swung at an improper angle the nonspaced adjacent stripes merge and form visible diagonal lines across the movement of travel of the club head.
Claim 3
Dependent Claim
56 words
The combination as specified in claim 1 wherein said luminescent material includes a light-emitting substance adapted to emit radiation in the visible range of the spectrum when ultraviolet radiation is impinged thereon and at least two of said adjacent stripes emit radiation resulting in at least visibly discernible hues when said ultraviolet radiation is impinged thereon.
Claim 4
Dependent Claim
21 words
The combination as specified in claim 2 wherein said stripes extend rearwardly from said forwardmost ends in a substantially straight line.
Claim 5
Dependent Claim
27 words
The combination as specified in claim 2 wherein said luminescent means further includes luminescent material disposed on the uppermost surface of said club head adjacent said stripes.
Claim 6
Dependent Claim
22 words
The combination as specified in claim 1 wherein said luminescent means comprises a decal secured to said uppermost surface of said head.
Claim 7
Dependent Claim
50 words
The combination of claim 1 wherein said stripes of luminescent material comprise a gauzelike material impregnated with a substance which will emit light when exposed to air, said material being carried within an air-tight transparent enclosure which can be punctured to admit air such that said substance will emit light.
Claim 8
Dependent Claim
24 words
The combination of claim 6 wherein one surface of said enclosure is provided with a pressure-sensitive adhesive adapted for connection to said club head.
Claim 9
Dependent Claim
98 words
In combination with a golf club having a shaft with a head at its lower end, luminescent means associated with said head of the golf club for permitting visual observation of the movement of said club head during the execution of a swing of said golf club, said luminescent means comprising an air-tight transparent enclosure incorporating means for securing it to said club head, and gauzelike material carried within said enclosure and impregnated with a substance which will emit light when exposed to air, said enclosure being puncturable to admit air and cause said substance to emit light.
Claim 10
Dependent Claim
98 words
In combination with a golf club having a shaft with a head at its lower end, luminescent means associated with said head of the golf club for permitting visual observation of the movement of said club head during the execution of a swing of said golf club, said luminescent means comprising an air-tight transparent enclosure incorporating means for securing it to said club head, and gauzelike material carried within said enclosure and impregnated with a substance which will emit light when exposed to air, said enclosure being puncturable to admit air and cause said substance to emit light.
