Background of the Invention

Technical Field

The present invention relates generally to a golf training aid, and more particularly, to a golf swing training aid for attaching to a club head, that comprises an illumination device and that is manually formable from a flat semi-rigid, joint-able material. Background Art

Golf is a popular sport for recreation and exercise. With the lowest possible number of strokes, a golfer uses a club to hit a golf ball into each hole of the golf course. The golf club consists of a shaft having a grip on the top and a club head on the bottom. Various types of clubs, such as "woods", "irons", "hybrids", and "putters", are used for the variety of shots presented by the particular course.

Improving the golf swing leads to achieving a lower score. Many golfers spend a considerable amount of time, money, and effort in pursuit of it. It is well known that an accurate golf shot depends on the golfer's stance, the grip, the correct swing plane, the proper perpendicular club head alignment at the moment of impact, and "hitting the sweet spot" by making ball contact with the club head in the very center of the club head face. Yet developing an accurate swing continues to be a challenge.

Due to the popularity of golf and the difficulty of achieving a consistent and reliable swing, numerous types of swing training aids have been developed. However, the conventionally available swing training aids are all deficient in one or more areas. Many swing training aids are heavy, bulky, or cumbersome. Often they have sizeable mounts for clamping the golf swing training aid to the shaft of the club. When attaching the training aid to the club, even the addition of a few ounces of weight is significant. With extra weight on the club, or with unbalanced weight as in some conventional devices, the swing is thrown off and the purpose of the training is defeated. Additionally, the rigid mounts and supported swing training aid that are attached to the end of a swinging club may be a safety hazard.

Some golf swing training aids cannot be used with a standard club. The swing training aid may be built into a training club, necessitating buying the club. Thus the user is required to swing a foreign club with different weight, angles, shaft lengths, etc. than his or her own club. The user practices his golf swing to develop muscle memory, yet if the swing training aid requires practicing with a foreign club, there will be a transition when the golfer moves to his own clubs in actual play. Thus the practice value is reduced.

Further, many conventionally available swing training aids cannot be used while actually striking the golf ball; therefore the practice is not realistic. Additionally, many conventional swing training aids are complex. Such aids have numerous electrical components, batteries, technical mechanical components, and/or delicate electronics that may fail. Also, transporting such complex devices in golf bags may damage them.

Some currently available golf aids do include one or more lights to assist in training the swing, but the provided lights are relatively expensive and are difficult to see, such as dot shaped LED's.

Other golf swing training aids are expensive, so are not readily available to every golfer. Also, currently available golf swing training aids are not economical for promotions and advertising, such as inclusion in "tournament packages", trade show giveaways, or other promotional uses.

Further, conventional golf swing training aids may be difficult to connect, to use, or to align. Proper alignment includes the following features: perpendicular to the club shaft, square to the club face, and indicators directly over the sweet spot. No currently available golf swing training aid has these alignment features. Thus, though varied swing training aids and mounts have been proposed, all suffer from one or more of the above disadvantages .

Accordingly, there is an established need for a simple, portable, easy to use, safe, durable, promotional and inexpensive golf swing training aid that provides the golfer with efficient guidance and training by giving immediate visual feedback on all of the most fundamental elements of a golf swing.

Disclosure of the Invention

The present invention is directed to an inexpensive golf swing training aid that is manually formable by the golfer from a prepared, uniquely constructed sheet-platform of semi-rigid, joint-able material (such as, for example, a small laminated Teslin^® or PVC plastic card) that may be imprinted with advertising, instruction, barcodes, magnetic stripes, or other desirable graphics, customizations, or markings. The golf swing training aid comprises a positioning flap, a horizontal flap, a hinged club- attachment flap, and an illumination device disposed on the horizontal flap.

Scoring (such as by perforation, pre-bending, kiss- cutting, stamped impressions, shallow cuts in the material, or the like) of the sheet-platform of semi-rigid, joint- able material facilitates the bending of the particular failure or score lines to form the positioning flap, horizontal flap, and hinged club-attachment flap. The preferably dual -color illumination device allows the golfer to view any misalignment in real time. The golfer can thus visualize, analyze, diagnose, correct, and improve his swing. An object of the present invention is to provide a golf swing training aid that can be printed with text, graphics, or other markings.

An additional object of the present invention is to provide a golf swing training aid that that can be used for many promotional and marketing purposes.

Another object of the present invention is to provide a golf swing training aid that that can be imprinted with instructional information. A further object of the present invention is to provide a golf swing training aid that is quite inexpensive .

Modes For Carrying Out the Invention

Shown throughout the figures, the present invention is directed toward an effective golf swing training aid that is manually formable by the golfer from a prepared, uniquely constructed sheet-platform (which may be of one or more layers) of semi-rigid, joint-able material backed by an adhesive layer. Not only does the golf swing training aid provide a beneficial service to the golfer, it also is customizable by standard printing techniques. Therefore, the golf swing training aid can also be used for promotional or marketing purposes when imprinted with graphics, text, or other markings. Thus the golf swing training aid provides a double advantage - to the advertiser or issuer and to the golfer end user. The golf swing training aid 100 generally comprises a positioning flap 70, a horizontal flap 80, a hinged club- attachment flap 90, and an illumination device 28 disposed on the horizontal flap 80. By detachment of particular areas (at "cuts") and by bending of other particular areas (at "joints") of the uniquely constructed sheet-platform of semi-rigid, joint-able material, the three flaps 70, 80, 90 are manually formed; then the golf swing training aid is aligned and adhesively adhered to the golf club head. The positioning flap 70 allows the golfer to correctly position the golf swing training aid 100 parallel to the horizontal grooves, common to almost all club faces, on the club 55 (FIG. 5). The horizontal flap 80, which provides a support base for illumination device 28, is properly aligned perpendicularly to the club shaft. For greater structural rigidity and alignment, the hinged club- attachment flap 90 is affixed to either the top and/or the back side of the club head, reinforcing the perpendicular alignment of horizontal flap 80.

Joints or hinges allow the semi-rigid, joint-able material to bend, pivot, or hinge without separating, yet allow the semi-rigid, joint-able material to remain fixed in the desired position. Scoring (such as by perforation, pre-bending, kiss-cutting, depression, micro-perforation, punching, die-cutting, laser cutting, stripping, varying thicknesses, abrading or other methods of creating stress or failure points, all herein referred to as "scoring") of the sheet-platform of semi-rigid, joint-able material facilitates the bending of the particular failure or score lines. For example, if laminated Teslin^® is used, the upper lamination 86 (FIG. 3A, FIG. 21) may be cut or pierced, allowing the Teslin^® and other substrates to flex at the integral joint. These joints formed by scoring the upper laminate layer allow the material to bend, pivot, or hinge without separating and allow the material to remain fixed in that position.

Cuts allow separation or detachment of one portion of the golf swing training aid from another portion. Cuts are generally formed by penetrating through substantially the entire card. Cuts can be performed by any standard finishing technique, such as, for example, die-cutting, laser cutting, guillotine trimming, slitting, abrading, and the like. The cuts would preferably not penetrate through the removable film 38 (FIG. 3A) .

Six exemplary embodiments of the golf swing training aid are presented, but other similar embodiments are within the scope of the invention. The first exemplary embodiment of FIG. 1 to FIG. 5 presents a first front-hinged club- attachment flap 90, the second embodiment of FIG. 6 presents a second front -hinged club-attachment flap 90, and the third embodiment of FIG. 12 to FIG. 15 presents a rear- hinged club-attachment flap 90, the fourth embodiment of FIG. 16, FIG. 17 presents a first combination-hinged club- attachment flap 90, the fifth embodiment of FIG. 18 presents a second combination-hinged club-attachment flap 90, and the sixth embodiment of FIG. 19 presents a golf swing training aid 10 embedded within a card or object. Referring now to the top view of FIG. 1, a first exemplary embodiment of a golf swing training aid, shown generally as reference number 100, is illustrated in accordance with a preferred embodiment of the present invention.

The hinged club-attachment flap 90 has three segments 90a, 90b, and 90c. Hinged club-attachment flap 90 is designed to be manually separated from horizontal flap 80 and from positioning flap 70 at cut lines 14, 62, 63, 64, and 65 by the user, but remains attached at a corresponding pair of pivotal hinges 77L and 77R disposed on a rearward portion of the golf swing training aid 100. Pivotal hinges 77L and 77R allow the hinged club-attachment flap 90 to pivot or bend with respect to the horizontal flap 80. The flexibility provided by pivotal hinges 77L and 77R allow the user to bend and flex the club-attachment flap 90 in a manner allowing it to be affixed to a surface of any of a variety of types and sizes of club heads. As shown in FIG. 2, the joints or hinges, created by scoring, comprise 10, 12L/12R, 16L/16R, 18L/18R, 20L/20R, 22, and 77L/77R. Joints 10, 12L/12R, 16L/16R, 18L/18R, and 20L/20R allow portions of the hinged club-attachment flap 90 to conform to the variety of textures and contours to which it may be attached. In one aspect of the present invention, the "ties" 15L/15R, 17L/17R, 23L/23R, and 27L/27R comprise minute connectors. For example, the minute connectors may remain uncut while the rest of cut lines 14, 62, 63, 64, and 65 are cut. The user then separates hinged club-attachment flap 90 from positioning flap 70 and horizontal flap 80 by disengaging the minute connectors at ties 15L/15R, 17L/17R, 23L/23R, and 27L/27R. These minute connectors allow the hinged club-attachment flap 90 to remain attached to the main body of the invention (positioning flap 70 and horizontal flap 80) until manually separated by the user. The number and the positioning of the ties are shown for examples only, as both the number and positioning may vary depending both on structural requirements or design elements.

In another aspect of the present invention, the cut lines 14, 62, 63, 64, and 65 are cut without leaving small uncut minute connectors at ties 15L/15R, 17L/17R, 23L/23R, 27L/27R. In this aspect the hinged club-attachment flap 90 is merely attached at the pair of corresponding pivotal hinges 77L, 77R. The user bends the club-attachment flap 90 at pivotal hinges 77L, 77R to pivot it with respect to the horizontal flap 80 and positioning flap 70. Illumination device 28 is disposed on horizontal flap 80, so as to be held aligned perpendicular to the shaft of the club, when the golf swing training aid is correctly installed on the club head. The manner in which illumination device 28 is attached or adhered to horizontal flap 80 may vary, but preferably a lower surface of the illumination device 28 is adhered to the top surface of the adhesive substrate 36. In the first embodiment cavity 26 houses illumination device 28 which comprises of one or more colors and/or lengths of an illumination or reflective device. Most preferably illumination device 28 comprises a light stick, glow stick, or other device that produces light through chemical-luminescence, but other small, low energy light sources or electronic light emitting devices may alternatively be used (such as, for example, a light emitting diode) . If another low energy light source is used, it may be installed with a small battery power source and a power switch (not shown) . Preferably illumination device 28 comprises a dual light of two colors of light, such as dual light sources 30, 32.

FIG. 3 and the detailed FIG. 3A are cut views illustrating the upper sheet-platform 8, an adhesive substrate 36, and a removable film 38. Adhesive substrate 36 is permanently adhered to the underside of sheet- platform 8. Adhesive substrate 36 is preferably made of a material with sponge or foam-like qualities, and contains an adhesive layer on the bottom which allows the invention to be attached to, and subsequently removed from, the club head 55 without leaving any residue. A common example of these properties is generally found in products known as "mounting tape" or "foam tape." The thickness of the adhesive substrate 36 (similarly to the mounting tape example) allows it to conform to a variety of textures and contours. Film 38 is removed prior to the attachment of the golf swing training aid to a club head 55.

The sheet-platform 8 is formed of a sheet of semirigid, joint-able material (or one or more layers) , which is preferably a semi-rigid but flexible or "joint-able" material, such as, for example, a laminated synthetic printing sheet substrate such as laminated Teslin^®, PVC plastic, PETG plastic, ABS plastic, high density polyethylene, polycarbonate, laminated paper, laminated Tyvex^®, laminated Artisyn^®, thick cardstock, plasticized fabric or fiber, silicone, thin aluminum, or another other suitable joint-able material having similar properties. In one aspect of the invention, the card can be made of a water proof, or water resistant, plastic to which graphics, artwork, text, or other markings can be applied, and then laminated with a clear laminate film. Most preferably a laminated Teslin^® may be used. The golf swing training aid is preferably in the size range of business cards, baggage tags, and credit cards (such as, for example, around 1 to 1.5 inches wide by 2.5 to 3.5 inches long) for convenience in carrying in a wallet with other plastic cards; however, other sizes are within the scope of the invention.

FIG. 4 is a perspective view of the golf swing training aid 100 of the present invention, showing main joint 22 with main side joints 20L/20R bent into position prior to detaching the hinged club-attachment flap 90 from positioning flap 70 and horizontal flap 80 and prior to attaching it to the golf club face 40 (FIG. 5) . Main joint 22 comprises a hinge which allows the user to align the horizontal flap 80 perpendicular to the shaft of the golf club 55.

As shown in FIG. 5 and FIG. 6, the alignment points 71 and 72 at the ends of face cut line 14 are used to properly align the invention parallel to the golf club face lines 44, which are common to almost all golf club heads 55. The downward-edge (face cut line 14) of positioning flap 70 is preferably elevated in the center to reduce interference with the club head striking surface or face 40, such as the arch of face cut line 14 of this embodiment. FIG. 6 illustrates a second exemplary embodiment in which the entire hinged club-attachment flap 90 can be manually detached at the position of pivotal hinges 77L and 77R. Optionally, the hinged club-attachment flap 90 can also remain attached and folded back and attached to another part of the wood head 40, similarly to the illustration of FIG. 5.

FIG. 7 is a diagram showing the visual representation of three general types of swing paths indicated by illumination device 28. Dashed line 51 represents the most desired swing path in which a tangent drawn from the golf ball point of contact 49 would be in line with the desired target. Line 52 represents a less desired swing path known as "outside/in." Likewise, line 54 represents a less desired swing path known as "inside/out."

FIG. 8 represents the visual "trail" left by illumination device 28 and viewable to the user while swinging the golf club. Line 56 and 58 represent the two trails left individually by illumination devices 30 and 32. Section 59 represents the proximate area surrounding the point of contact that the club head has with the golf ball. The dual light sources 30, 32 of illumination device 28 allow the user to see an illuminated representation, or "trail," of the user's golf swing and allow the user to visually determine an alignment or misalignment. Foremost, this trail allows the user to track the path of the club head 55 at the point of contact with the golf ball to ensure, and to practice, the desired swing path. Secondly, through the use of two or more colors of light sources 30, 32, the user can see an illuminated representation of the club head alignment surrounding the point of contact with the golf ball. If both colors appear as a straight line at the point of contact, then the user knows that the club head 55 is perpendicular with the desired target line. If the colors appear laterally separated at the point of contact, then the user knows that the club face is either "closed" or "open" based upon the orientation of the two different colors. The dual light sources 30, 32 of illumination device 28 can be attached to the invention in several ways. The first embodiment of FIG. 1 shows dual light sources 30, 32 recessed in cavity 26 and adhered directly to substrate 36. Illumination device 28 can be attached by other means such as glue, housings, tape, can be self-adhering, or otherwise affixed. Optionally, self-adhering illumination strips, sticks, or dots of the same or different colors can be applied to the invention, by the user, in different orientations in order to show different elements of the golf swing. Under such permutations, the user can apply the illumination devices directly to the club head 55, the club face 40, or other parts of the golf club in order to illuminate the various elements or portions of the golf swing. Furthermore, additional illumination devices can also be applied to the ground, a golf tee(s), or otherwise, so that a point (s) of reference can be established for a golf swing.

FIG. 9 represents a permutation of section 59 in which the club face is perpendicular to the target line or tangent line drawn from point 49 and swing path 51 in FIG. 7. The perpendicular alignment is indicated by the fact that 56 and 58 are not laterally separated.

FIG. 10 represents a permutation of section 59 in which the club face 40 is "closed" at the point of contact. This particular alignment is represented by a visual separation of illumination devices 30 and 32 during the course of the swing (near the point of impact) .

FIG. 11 represents a permutation of section 59 in which the club face 40 is "open" at the point of contact. This particular alignment is represented by a visual separation of illumination devices 30 and 32 during the course of the swing (near the point of impact) . FIG. 12 illustrates a preferred third exemplary embodiment of the golf swing training aid 100 printed with text, graphics, or other markings 95. As in the first two embodiments, the golf swing training aid 100 of the third embodiment comprises positioning flap 70, horizontal flap 80, hinged club-attachment flap 90, and cavity 26 housing illumination device 28. However, the golf swing training aid 100 of the third embodiment illustrates a variation in the rearward placement of hinged club-attachment flap 90 and the central placement of pivotal hinges 77L, 77R.

The positioning flap 70 comprises the entire front portion of the sheet-platform 8. As in the other embodiments, alignment points 71 and 72 are used to align positioning flap 70 before adhering it to the golf club. As in the other embodiments, the golf swing training aid 100 is bent along score line of main joint 22 to allow perpendicular positioning of the horizontal flap 80.

To add structural rigidity and to ensure a perpendicular alignment of horizontal flap 80 with respect to the club shaft, hinged club-attachment flap 90 can be jointed at pivotal hinges 77L, 77R, and separated at cut line 60 to additionally secure the golf swing training aid to either the top or back side of the club head 55. Pivotal hinges 77L, 77R allow the hinged club-attachment flap 90 to be manipulated toward and attached to the club head 55.

Hinged club-attachment flap 90 can be easily attached to a multitude of golf club head types - whether wood, iron, hybrid, or other. Two possible arrangements of hinged club-attachment flap 90 are presented in FIG. 14 and FIG. 15. FIG. 14 shows a slight downward bending at pivotal hinges 77L, 77R of hinged club-attachment flap 90 with attachment to the top of the club head 55. FIG. 15 shows a sharp bend at hinges 77L, 77R so that hinged club- attachment flap 90 is manually attachable to the back of club head 55.

Optionally, other similar embodiments can be created by varying the joints and scoring for detachment and for bending. For example, perforated lines 97, 98 (FIG. 12) can be extended to positioning flap 70 such that main side joints 77L and 77R are placed between alignment points 71 and 72 and main joint 22. Positioning flap 70 can then be shortened such that it becomes two separate tabs just long enough to wrap the back of an iron head. A series of additional joints can be added so that the two individual tabs can achieve a greater conformity and attachment directly to the top of the iron head, and still function properly when applied to other club head types. A fourth exemplary embodiment, which functions in a similar manner to the golf swing training aid 100 of the first three embodiments, is illustrated in FIG. 16. FIG. 16 is a top view of the main component, sheet-platform 8 (FIG. 3), which is preferably manufactured from a sheet of semi-rigid, joint-able material. The joints (35L/35R, 37L/37R, 22, 20L/20R, 41L/41R, 47L/47R, 77L/77R, 74, 78, 76, and 79L/79R) , created by scoring, allow the bending needed to position and attach the golf swing training aid. Cut lines 43L/43R, 59L/59R, and 60 are nearly complete perforations but for minute connectors 39L/39R, 49L/49R, 97L/97R, and 96L/96R. These connectors allow the separate pieces to remain attached until manually separated by the user. Illumination device 30 and 32 is disposed on horizontal flap 80.

The club-attachment flap comprises three segments, as follows: a rear club-attachment flap 9OA, an independent right club-attachment flap 9OC, and an independent left club-attachment flap 9OB. As shown in the functional perspective view of FIG. 17, alignment points 71 and 72 are used to align the front of the invention parallel to horizontal groove lines 44. The user can then bend the invention at main joint 22 to position horizontal flap 80 perpendicular with respect to the shaft of the golf club. FIG. 17 shows a perspective view of the invention bent at main joint 22, having a complete separation of cut lines 43L/43R, 59L/59R, and with the three club attachment flaps 9OA, 9OB, 9OC independently folded over and attached to the back of the club head 55.

For added structural rigidity and a more secure perpendicular alignment of the main body of the invention, the two front and one rear club-attachment flaps 9OA, 9OB, 9OC can be manually detached and secured to a variety of golf club heads 55 as shown in FIG. 17. The front left club-attachment flap 9OC comprises joints 35L, 37L, 2OL, 41L, and 47L with cut line 59L. The front right club- attachment flap 9OB comprises of joints 35R, 37R, 2OR, 41R, and 47R with cut line 59R. The rear club-attachment flap 9OA is attached at pivotal hinge 77L/77R and comprises joints 74, 78, 76, and 79L/79R. Thus, similarly to the other exemplary embodiments, the club-attachment flaps 9OA, 9OB, and 9OC comprise a series of joints which allow the club-attachment flaps 9OA, 9OB, and 9OC to conform to a variety of textures and contours.

A fifth exemplary embodiment, which functions in a similar manner to the golf swing training aid 100 of the first four embodiments, is illustrated in FIG. 18. Generally, the fifth embodiment is comparable to the fourth embodiment without club-attachment flap 9OA; therefore, the fifth embodiment illustrates only an independent right club-attachment flap 9OC and an independent left club- attachment flap 9OB. The score lines and minute connectors are also comparable with the fourth embodiment of FIG. 16.

While the golf swing training aid 100 of the present invention can be manufactured as a single, separate device as illustrated in the above figures, FIG. 19 and FIG. 20 illustrate an alternative configuration. The golf swing training aid 100 can optionally be inset within a card or tag size (or alternatively, other size) sheet of semirigid, joint-able material. When inset within a card, cut lines 14, 66, 67 along the perimeter of the golf swing training aid allow the golf swing training aid to be detached from the external card. Ties or minute connections (not shown) of various numbers and placements may be utilized to hold the golf swing training aid within the external card before detachment.

The sixth embodiment of FIG. 19 also illustrates the provision of a varied exterior perimeter of the golf swing training aid 100. The face cut line 14 is illustrated as a stepped cut line, as opposed to the arched line of the other embodiments. Due to the method of manufacture, the outlines of face cut line 14, as well as the other perimeter lines 66, 67 can easily be varied to meet layout, pattern, or motif designs, and such varied perimeter lines are within the scope of the invention. This may be desirable in customization or personalization of the golf swing training aid 100. For instance, the logo 93 comprises a stepped line portion. Therefore, to meet design goals for a unique, attention-getting product, the face cut line 14 may be the reciprocal of the stepped line of logo 93.

Whether fabricated separately or inset within a sheet of semi-rigid, joint-able material, the golf swing training aid 100 can be imprinted, embossed, or otherwise marked with any of a variety of graphics or text 95, logos 93, magnetic stripes, or bar codes. Such markings may be on the golf swing training aid itself, on a card containing the golf swing training aid 100, or extending over both the golf swing training aid 100 and card. Such marking may be desirable for any of a variety of commercial or private distributions. Such markings comprise detailed graphics, instructional diagrams, promotional or marketing symbols, redeemable coupons, text, barcodes, magnetic stripes, photos, or the like. The golf swing training aid 100 can be used as a customized retail product, an item in a tournament package, as a tradeshow give-away, as a clothing tag such as for golf attire, as a business card, as a personalized gift, as a luggage tag, within a mailing for advertisement purposes, as a small gift embedded within a plastic sheet such as in a birthday card or in an instructional book cover, as a memento of an occasion, or as a product that is incorporated into, and removable from, other types of items. Other non-functional piercings or holes 99 (FIG. 18, FIG. 19) unrelated to the functioning of the golf swing training aid 100 may optionally be included, such as, for example, when the golf swing training aid 100 is prepared to attach to a golf bag, to a purse, or to a key chain or when non-functional holes 99 may be advantageously incorporated into a desired, customized design.

Referring now to FIG. 21, a preferred manufacturing method is illustrated. Five layers are presented, as follows: the top first laminate layer 86, a printable sheet substrate layer 87, a second laminate layer 88, an adhesive layer 36, and removable film 38. The first laminate layer 86, printable sheet substrate layer 87, and second laminate layer 88 most preferably have a thickness of around 10 ml. The first laminate layer 86, printable sheet substrate layer 87, and second laminate layer 88 all have a cavity 81, 83, 84 for receiving glow stick 85. First laminate layer 86, a printable sheet substrate layer 87, a second laminate layer 88 comprise sheet-platform 8 of FIG. 3A. Most preferably the printable sheet substrate layer 87 comprises a Teslin^® synthetic printing sheet substrate and the adhesive layer 36 comprises a foam-tape-type material. The manufacture steps generally include the following: 1. Printing the printable sheet substrate layer 87 with graphics, text, or other markings; 2. Laminating both upper and lower surfaces of printable sheet substrate layer 87 with upper first laminate layer 86 and lower second laminate layer 88; 3. Cut through laminated printable sheet substrate, forming interior and perimeter cuts. Interior cuts may be used to form cavities 81, 83, 84 in first laminate layer 86, printable sheet substrate layer 87, and second laminate layer 88; 4. Cut only top laminate layer 86 at all joints 91, but leave in sheet (generally performed at the same time as step 3. Specifically, the joined layers may be put into a press having "steel -rule dies" of varying but precise depths. The joints are formed by a blade piercing part, or all, of the top laminate layer, while other blades simultaneously cut the perimeter and interior cuts.); 5. Adhere adhesive layer 36 on lower surface of second laminate layer 88, preferably by lamination (a removable film 38 [FIG. 3A] is preferably previously attached to cover the lower adhesive surface until the end user is ready to use the golf swing training aid); 6. Punch out external perimeter 92 (FIG. 3, FIG. 21) of joined layers 86, 87, 88, 36, and 38; and 7. Insert glow stick into cavity 81, 83, 84, preferably by adhering glow stick 85 to the top surface of adhesive layer 36.

The golf swing training aid 100 may be manufactured using conventional card cutting methods, such as, for example, stamping, die cutting, or laser cutting on a moving web or on individual unmoving sheets, or injection molding, or thermoforming . Preferably the golf swing training aid 100 is stamped for economy of production. Further, the edges may be beveled, creating a smooth feel and minimizing scratches that could occur from raw edges.

To use the golf swing training aid 100 of the present invention, the prepared, uniquely constructed sheet - platform of semi-rigid, joint-able material is manipulated to form the positioning flap 70, horizontal flap 80, and hinged club-attachment flap 90. Main joint 22 is bent to generally create a right angle between horizontal flap 80 and positioning flap 70.

If illumination device 28 comprises two light sticks for dual light sources 30, 32, the divider (s) isolating the two or more substances contained within the dual light sources 30, 32 is (are) broken to allow the chemical- luminescence to begin.

Removable film 38 (FIG. 21) is removed from the back of the golf swing training aid 100, revealing the adhesive substrate 36.

Alignment points 71 and 72 at the ends of face cut line 14 on positioning flap 70 are properly aligned parallel to the golf club face groove lines 44. The adhesive substrate 36 on the back of positioning flap 70 is then adhered to the face 40 of club head 55.

The main joint 22 is manipulated to allow horizontal flap 80 to be positioned perpendicular to the shaft of the golf club. The one or more hinged club-attachment flap(s) 90 are bent and manipulated to create a supportive reinforcement to the perpendicular horizontal flap 80 position, attaching to the club head 55 (either the back or top) for the best support. The variety of hinges and joints allow efficient attachment to any of the golfer's own clubs, including both right and left handed clubs. The negligible weight of the golf swing training aid 100 allows the golfer to practice effectively. The simplicity of design provides an inexpensive, yet robust product that is easily installed and has no mechanical or moving parts to deteriorate or to add cost . The golfer then can begin to practice swinging; with the installed golf swing training aid 100 the golfer views the vibrant bands of colored light, allowing him to judge the alignment or misalignment of his swing and of the angle of the face of the club at impact.

By analyzing the trail patterns (FIG. 8 - FIG. 11) of the dual colored lights during the swing, the usually imperceptible elements of his golf swing (such as the swing plane, perpendicular club head alignment at impact, and sweet spot alignment) become apparent to him. He can then adjust various aspects of his swing and immediately receive feedback as to the results with each variation.

After use, the golf swing training aid 100 is readily detachable and disposable. In use, the golf swing training aid 100 of the present invention enables alignment with all proper alignment features. It provides a method to align the aid square to the club face and perpendicular to the club shaft, plus it has indicators (illumination device 28) directly over the sweet spot .

While six embodiments are herein presented, their presentation is merely exemplary and not limiting. Other variations are within the scope of the invention, such as one or more of the following: variations in the semi-rigid, joint-able material; variations in the manufacturing techniques of the golf swing training aid; variations in the attachment of the illumination device 28; variations in the type of illumination device 28; variations in the printing, embossing, or otherwise marking of the face or of the removable film 38; variations in the type of device attached to sheet -platform 8 in order to show different elements of a golf swing; variations in placement of the hinges; variations in the types of adhesive substrate 36. At times it may be desirable to attach, adhere, or embed other elements or products to, or within, the substrate of the sheet-platform 8; for example, glitter, synthetic gems, bits of metal, loops, small beads of a varied color of plastic, mirrored or reflective material, or the like may be used to add embellishment or to complement a customized design.

From the foregoing, it will be apparent that the golf swing training aid 100 of the current invention provides a convenient and inexpensive yet effective aid to improve a golfer's swing, while providing an opportune medium upon which advertising or promotional information can be distributed. Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents .
