[0003] The present invention relates to golf swing trainers, and more specifically to laser trainers that clip-on to the shaft of a golf club.BACKGROUND

[0004] Laser devices designed to attach to golf clubs are valuable tools for improving swing mechanics, offering visual feedback during practice. These devices typically attach to either the club's grip or shaft and project laser beams onto the ground to illustrate the swing's path and plane. By providing real-time insights, laser trainers help golfers identify and correct flaws in their technique. Their ability to be mounted on a golfer's own clubs allows practice with familiar equipment, making them a popular choice for skill refinement.

[0005] Several patented laser training devices have been developed to attach to the grip of a golf club, each with unique features. The Plane Sight, Inc. patent (U.S. Pat. No. 5,544,888) and the McPherson, Jr. patent (U.S. Pat. No. 5,655,973) describe single-laser trainers that attach to the end of the club grip, providing feedback on alignment and swing mechanics. The Shapiro patent (U.S. Pat. No. 5,788,582), however, introduces a dual-laser design that wraps around the golfer's hands, projecting two beams to deliver a more detailed visualization of the swing path and plane.

[0006] While these grip-mounted devices can be useful, they present several limitations. First, they interfere with the golfer's natural grip, restricting hand placement and movement, which can impact comfort and swing consistency. The added weight at the grip end also disrupts swing dynamics, creating unrealistic practice conditions and risking poor muscle memory. Moreover, grip-mounted devices are typically difficult to attach and remove, making it cumbersome to switch them on and off, particularly when practicing with multiple clubs. Another issue with grip-mounted devices is their inconsistent accuracy. Rubber grips are flexible and compressible, which can cause these devices to shift during use, reducing their reliability.

[0007] A potential solution to these challenges is a laser trainer that attaches to the club shaft. For example, the Rodney L. Nelson patent (U.S. Pat. No. 3,953,034) describes a single-laser trainer that projects a beam down the shaft onto a mirror, converting it into a dispersed fan of light. Similarly, the Adam L. Coates patent (U.S. Pat. No. 7,160,198) features a shaft-mounted device secured with screws, clasps, or latches, utilizing multiple angled lasers to provide feedback on the swing plane, clubhead position, and clubface orientation.

[0008] Despite these advantages, existing shaft-mounted laser trainers have limitations. Notably, they lack a dual-laser system aligned on a single axis. Such a system could project lasers forward and backward, creating a unified “lane” that clearly illustrates the swing path and plane at every stage. Current designs, whether single or multi-laser, do not provide a comprehensive view of the clubhead's movement, making it difficult to identify whether the swing is too steep or shallow.

[0009] Another drawback of existing shaft-mounted devices is their cumbersome attachment systems, which often rely on screws, clamps, or latches. These methods make it challenging to switch the trainer between clubs, limiting versatility for practicing different shots, such as those with drivers, irons, or wedges. Additionally, these attachment methods can leave marks, adhesive residue, or even cause wear on the club shaft. A clip-on design would address these issues, offering easy attachment and removal, seamless transitions between practice and play, and use across multiple clubs, making the trainer more practical and economical.

[0010] Finally, many current designs feature fixed, non-removable lasers, which limits their adaptability. Such lasers cannot be repurposed for other training tools, such as short-shafted swing laser trainers, reducing their flexibility for various practice scenarios. This restriction prevents golfers from tailoring their training setups for specific needs, such as indoor versus outdoor practice. A modular design with detachable lasers would enhance versatility, enabling golfers to transition smoothly between standalone practice tools and real-club training.SUMMARY

[0011] The present invention relates to a laser trainer that clips onto a golf club shaft, addressing the shortcomings of existing designs and delivering a more effective, versatile, and user-friendly training tool for golfers. This innovative trainer features dual lasers precisely aligned on a single axis, projecting in opposite directions. One laser projects downward, tracing the swing path, while the other projects upward, visualizing the swing plane. This dual-laser configuration provides a clear and continuous representation of a single swing plane, offering real-time feedback to help golfers identify and correct flaws, such as swings that are too steep or too shallow.

[0012] The trainer incorporates a quick-clip attachment system, allowing it to snap on and off club shafts effortlessly without the need for screws, clamps, or clasps. This design ensures that golfers can quickly transition the trainer between different clubs, from wedges to drivers, during practice sessions. The simplicity and speed of this mechanism enhance convenience while eliminating the risk of marks, residue, or potential damage to the club shaft.

[0013] Additionally, the trainer has a modular design with removable lasers, which can be repurposed for use with other golf training tools, such as short-shafted laser swing trainers. This adaptability increases the device's versatility, making it suitable for various practice scenarios, whether indoors or outdoors. By allowing golfers to customize their training setups, the removable lasers add significant value for players of all skill levels.BRIEF DESCRIPTION OF DRAWINGS

[0033] Referring now in detail to the drawings, FIGS. 1 and 2 provide a perspective view of the device. As depicted, the device consists of three primary components: the clip 11, stem 13, and the laser holders 16, 17.

[0034] The clip 11 is the part of the device that attaches securely to the golf club shaft. Shaped like the letter “C,” the clip 11 features a central hole and a gap in its circumference, enabling easy attachment to the shaft. Its rounded design conforms to the cylindrical shape of a golf club shaft. The clip's diameter is smaller than the thickest part of an average golf club shaft but larger than the thinnest part, allowing the user to clip the device onto the lower, thinner section of the shaft and slide it upward until it fits tightly on the thicker section. This design ensures a secure and stable attachment during use.

[0035] As illustrated in FIG. 2, the laser holders 16, 17 are identical in size and shape. Each holder has external threads on one end, designed to screw into a corresponding laser holder nut 15, securing the laser in place. The opposite side of the holder features a top hole. As shown in FIG. 7, the interior of each laser holder contains an empty cylindrical chamber, which houses and stabilizes the laser.

[0036] As seen in FIGS. 8 and 9, the device incorporates two lasers 18, 19, each housed in its own laser chamber 16, 17 and oriented in opposite directions. Despite being in separate chambers, the lasers share a connection through the laser holder nut 15. Each laser has an output power range of 1 to 4.99 milliwatts, classifying them as Class 3R lasers. They are powered by three LR44 batteries and feature a button at the rear for simple on / off activation with a quick press. The lasers are removable, allowing for flexible reconfiguration. For example, they can be transferred to a secondary training device, such as a short-shafted golf laser swing trainer, enabling golfers to alternate between practicing with their actual clubs and focusing on swing mechanics using a short-shafted laser trainer.

[0037] When inserted, the lasers 18, 19 are positioned so that their buttons rest against each other as seen in FIG. 7. The laser holders 16, 17 are designed with a central hole, large enough for the laser beam to pass through and for the user to insert a finger. Pressing down on the laser through this hole activates or deactivates the on / off button without requiring the laser to be removed from the chamber. This feature ensures convenient operation while maintaining the stability and alignment of the device during use.

[0038] As shown in FIG. 3, another key component of the device is the stem 13. On one end of the stem is the clip 11, while the other end is the laser holder nut 15. The laser holder nut is equipped with internal threads that allow the laser holders 16, 17 to be securely fastened in place.

[0039] As illustrated in FIGS. 1 and 2, the stem 13 serves an essential function by positioning the lasers 18, 19 at a distance from the golf club shaft. This placement ensures the laser beams can project unobstructed onto the target line in front of the golf club head. The design keeps the lasers far enough from the shaft to prevent the beams from being blocked by the golfer's hands when gripping the club. To enhance stability and durability, the stem flares outward at both ends 12, 14, providing additional support for the clip 11 and the laser holder nut 15.Operation

[0040] To use the device, the user starts by unscrewing one of the laser holders 16, 17 and inserting the lasers 18, 19. The lasers are positioned to face in opposite directions, with their beams aligned to project out of the laser holder holes and their buttons in contact with each other. Once the lasers are properly aligned, the laser holder is screwed securely back into place. To activate the lasers 18, 19, the user inserts a finger into the laser holder hole and presses down, engaging the on / off buttons. With the lasers activated, the device is ready for use.

[0041] To practice a swing that follows the correct path and plane, the user assumes their normal stance and aligns the laser with either the target line or the shaft line, based on their preference. The target line is an imaginary line extending indefinitely between the target and the ball, while the shaft line runs parallel to the target line, approximately 1.5 inches below the ball placement and extending in both directions.

[0042] As seen in FIG. 10, the objective is to keep the laser dots aligned along a straight line (usually target or shaft line depending on user's preference) parallel to the user's feet throughout the swing. When the hands are below waist level, the front laser should remain on the line; when the hands are above waist level, the back laser should stay on the same line.

[0043] If the laser moves inside the shaft or target line, it indicates that the swing is too steep, which may result in a draw, hook, or an over-the-top motion on the downswing. Conversely, if the laser moves outside the shaft or target line, it suggests a swing that is too flat, potentially causing a slice or fade.Advantages

[0044] From the description above, several advantages of my dual laser clip-on golf swing trainer become evident:

[0045] a. The dual lasers provide a clear and continuous visual representation of the swing path and plane throughout the entire motion. The forward-pointing laser highlights the path of the clubhead toward the target, while the backward-pointing laser reveals the backswing and initial downswing plane. This setup helps golfers maintain proper alignment and detect inconsistencies in their swing.

[0046] b. With the lasers aligned on a single axis, the device creates a unified “lane” for the swing. This feature helps golfers ensure the club is traveling on the correct plane at every stage, reducing common issues like a steep or shallow swing path. A visual cue for staying within a defined plane promotes muscle memory and consistency.

[0047] c. The device provides immediate, real-time feedback during practice. Any deviations from the intended swing path or plane are instantly visible, enabling golfers to identify and correct errors on the spot without requiring a coach or video analysis.

[0048] d. The clip-on design allows the trainer to be easily attached to or removed from any club shaft, from wedges to drivers. This versatility enables golfers to practice different types of shots with the same device, enhancing its utility and value.

[0049] e. By mounting the lasers on the shaft and positioning them away from the grip, the trainer avoids interference with the golfer's natural hand placement. This ensures that the tactile feel of the club remains unchanged, providing a more realistic practice experience.

[0050] f. The clip-on mechanism eliminates the need for screws, clamps, or adhesives, allowing for quick and secure attachment. This convenience makes it easy for golfers to switch the trainer between clubs or remove it when transitioning to regular play.

[0051] g. By focusing on a single plane, the dual-laser system helps golfers improve their swing mechanics more efficiently. The ability to visualize both the backswing and the forward swing in real time accelerates learning and reduces the need for prolonged trial and error.

[0052] h. The device's compact size and lightweight construction make it easy to carry in a golf bag or pocket. Golfers can bring it to the range or use it at home for swing training.

[0053] i. By consistently practicing with visual cues for the correct swing path and plane, golfers can develop stronger muscle memory. This leads to more confident swings and better performance on the course.Conclusion

[0054] Accordingly, the reader will see that a dual laser clip-on golf laser trainer, with lasers positioned on top of each other and pointing in opposite directions, provides a comprehensive and accurate visualization of the swing path and plane. The forward laser highlights the target line, while the backward laser tracks the backswing and initial downswing. Together, they create a single “lane” that helps golfers ensure their swing stays on the correct plane at every stage. This feature reduces common swing flaws like steep or shallow paths, fostering improved consistency and muscle memory.

[0055] The clip-on design ensures the trainer is versatile and user-friendly. Unlike devices that require screws or clamps, this trainer can be quickly attached or removed, making it easy to use across various clubs, from wedges to drivers. Its positioning on the shaft, rather than the grip, avoids interference with the golfer's natural hand placement, preserving the feel and dynamics of the club. The trainer's lightweight and portable design further enhance its convenience, allowing golfers to practice effectively both indoors and outdoors.

[0056] With immediate visual feedback, golfers can identify and correct errors in real time, making practice sessions more efficient and impactful. The dual-laser system accelerates learning by simplifying the process of refining swing mechanics. Whether used for individual practice or integrated into coaching sessions, this trainer helps golfers build confidence and develop consistent swing habits, ultimately improving their performance on the course.

[0057] Another valuable feature of the trainer is its removable lasers, which can be used with other golf training devices, such as a short-shafted golf laser swing trainer. This flexibility ensures consistency across different tools, making it easier to transition from standalone practice to real-club swings. By utilizing dual-purpose lasers, users save on equipment costs and eliminate the need for duplicates. The removable design allows effortless switching between trainers, accommodating both indoor and outdoor practice.

[0058] With its features, the dual laser clip-on golf swing trainer stands out as a superior golf laser trainer, enabling users to practice their swing, correct errors, and maintain proper club path and plane. By fostering accurate muscle memory, this device helps users develop better swing habits, ultimately enhancing their performance and enjoyment of the game.
