[0004] The present disclosure relates to a training system that utilizes a set of swing speed trainers with interchangeable weights to improve swing speed for sports such as golf.BACKGROUND

[0005] Club head speed, the speed at which the head of a golf club travels, significantly influences the distance and performance of an impacted golf ball's flight. Many golfers aim to increase their club head speed, especially at the moment of impact with the golf ball. Various training regimens and devices have been developed for this purpose. One notable method is the SuperSpeed™ Golf training system, which uses a set of weighted clubs to enhance swing speed through “overspeed” training drills. Increased swing speed is crucial not only in golf but also in other sports like baseball and tennis. Athletes trained by overspeed training increase maximum swing speed which translates to higher ball velocities and longer distances achieved. Training devices have also been created to encourage proper technique and provide feedback to athletes about their swing speed through audible or physical cues.SUMMARY

[0006] The golf swing speed trainer has a weight tip. In profile, the weight tip has an elongated teardrop shape. The weight tip has a bulbous trail end structured to receive a weight plug. The weight plug has a rounded trail end structured to match the curvature of the bulbous trail end of the weight tip to form a low profile. An airfoil member may extend radially outward from the weight tip. In profile, the airfoil member has an elongated teardrop shape. The airfoil member has a bulbous lead end and a converging trail end. A converging lead end of the weight tip is structured to receive a distal end of a shaft of the golf swing speed trainer. The golf swing speed trainer may have a grip structured to be received by a proximal end of the shaft of the golf swing speed trainer. The grip has a compression zone structured to increase grip pressure. The compression zone may have a pad layer that is smooth. The compression zone may increase the grip pressure by a proximal portion of a trainee's lead hand. The grip may have a second compression zone structured to increase grip pressure. The second compression zone may increase the grip pressure by a distal portion of the trainee's trail hand. The grip has a decompression zone structured to decrease grip pressure. The decompression zone may have a stiff layer that is textured. The decompression zone may increase the grip pressure by a distal portion of the trainee's lead hand and a proximal portion of the trainee's trail hand. The decompression zone may be disposed between the first compression zone and the second compression zone. The weight tip has an internal cavity disposed in the bulbous trail end. The internal cavity is complementary structured to threadedly receive the weight plug. The weight plug is distally received by the weight tip from a distal end of the trainer.

[0018] A swing speed trainer may be used in a swing training system to improve the speed of an athletic swing. The swing speed trainer may be structured to decrease swing drag for increased swing velocity when swung by a trainee like an athletic club. In one example, the swing speed trainer may be structured to be swung in a manner like a golf club to promote the trainee to swing faster than normal during a golf swing motion.

[0019] A set of swing speed trainers may be used as training instruments in the swing training system. A plurality of swing speed trainers 1000 are shown in FIG. 1. The plurality of swing speed trainers 1000 may be specifically weighted relative to a golfer's personal club, such as a driver. The plurality of swing speed trainers 1000 are intended for use with specific training protocols in an overspeed training program to increase the golfer's club head speed and ball drive distance.

[0020] For overspeed training to be effective, the plurality of swing speed trainers 1000 are structured to take into consideration that different golf clubs and drivers on the market have different total weights. Therefore, the plurality of swing speed trainers 1000 may be customized by a trainee 10 with interchangeable weights to adjust for variances found in inertial properties between personal golf clubs and drivers.

[0021] A color-coding scheme may be applied to the plurality of swing speed trainers 1000 to differentiate between the specifically weighted trainers. The plurality of swing speed trainers 1000 may include a first swing trainer 110 with a green color scheme 115, known as the “light club”, a second swing trainer 120 with a blue color scheme 125, known as the “medium club”, and a third swing trainer 130 with a red color scheme 135, known as the “heavy club”.

[0022] The light club may be specifically weighted to have a relative weight variance of approximately 20% to 40% less than the total weight of a standard driver used by a golfer. The medium club may be specifically weighted to have a relative weight variance of approximately 1% to 20% less than the total weight of a standard driver used by a golfer. The heavy club may be specifically weighted to have a relative weight variance of approximately 1% to 25% more than the total weight of a standard driver used by a golfer. In a preferred example, the relative weight variances of the swing speed trainers are approximately −20% to −30% for the light club, approximately −10% to −20% for the medium club, and approximately +1% to +10% for the heavy club relative to the total weight of a standard driver used by a golfer.

[0023] The first swing trainer 110 and / or second swing trainer 120 may be structured to be lighter in weight relative to the total weight of a golfer's driver. In one example, the golfer's driver may have a total weight of 300 grams. The first swing trainer 110 may have a total weight of 240 grams which is 20% lighter than the total weight of the golfer's driver. The second swing trainer 120 may have a total weight of 270 grams which is 10% lighter than the total weight of the golfer's driver. As a result, the first swing trainer 110 and second swing trainer 120 may have less resistance to a change in motion, or less inertia, during the swing motion relative to the golfer's driver.

[0024] In contrast, the third swing trainer 130 may be structured to be heavier in weight relative to the total weight of a golfer's driver. The third swing trainer 130 may have a total weight of 315 grams which is 5% heavier than the total weight of the golfer's driver. As a result, the third swing trainer 130 may have more resistance to a change in motion, or more inertia, during the swing motion relative to the golfer's driver.

[0025] An example of a weight tip 200 for a swing speed trainer 100 is shown in FIG. 2. The weight tip 200 may be sold individually or as a set of weight tips in a swing trainer kit. The weight tip 200 is aerodynamically structured to move through the air with decreased drag resistance for increased swing speed during the athletic swing. The aerodynamic shape of the weight tip 200 is tapered to allow for efficient air flow along and around the exterior surface 205 of the weight tip 200. The aerodynamic shape of the weight tip 200 may promote increased swing speed during transition from the initial downswing, through the perceived moment of impact with a golf ball, and / or follow-through of the swing. For example, airflow moving down the shaft toward the distal end of the trainer during the initial downswing may disperse efficiently around the shape of the weight tip 200 which may result in increased swing speed by the trainee 10.

[0026] The weight tip 200 has an elongated body 204 that may be tapered. The elongated body 204 may have a converging lead end 202 and a bulbous trail end 206. The converging lead end 202 may be concavely rounded along a tapered section of the elongated body 204. The bulbous trail end 206 may be convexly rounded adjacent an annular rim 415 disposed at a distal end 208 of the weight tip 200. As a result, the elongated body 204 may have a shape like that of an elongated teardrop or a bullet in profile or cross-section.

[0027] The weight tip 200 may be manufactured by machining tools such as a computer numerical control (CNC) machine and methods such as milling, casting, mold injecting, turning with a lathe, or by other machining tools and methods. The weight tip 200 may be made of metal such as stainless steel or other durable metal alloy. As shown in FIG. 3, the weight tip 200 may be attached with epoxy to a tapered shaft 500 of the swing speed trainer 100. Alternatively, as shown in FIG. 4, a tapered fastener 300, such as a ferrule, ring, band, or other fastener, may secure the weight tip 200 to the tapered shaft 500.

[0028] A plurality of airfoil members 240, ridges, or other airflow modulators may extend radially outward from the weight tip 200. Referring to FIG. 2, the plurality of airfoil members 240 may comprise a first airfoil member 210, a second airfoil member 220, and a third airfoil member 230. The plurality of airfoil members 240 are shown disposed about a circumference on an exterior surface 205 of the weight tip 200. Each airfoil member is shown radially disposed at an angle (α) of approximately 120 degrees from one another relative to a central longitudinal axis 250 of the weight tip 200.

[0029] In a different example, a set of four airfoil members are disposed about a circumference on the exterior surface 205 of the weight tip 200. Each airfoil member may be radially disposed at an angle (α) of approximately 90 degrees from one another relative to a central longitudinal axis 250 of the weight tip 200. In another example, a set of five airfoil members are disposed about a circumference on the exterior surface 205 of the weight tip 200. Each airfoil member may be radially disposed at an angle (α) of approximately 72 degrees from one another relative to a central longitudinal axis 250 of the weight tip 200. In another example, a set of six airfoil members are disposed about a circumference on the exterior surface 205 of the weight tip 200. Each airfoil member may be radially disposed at an angle (α) of approximately 60 degrees from one another relative to a central longitudinal axis 250 of the weight tip 200.

[0030] The weight tip 200 may include the first airfoil member 210. The first airfoil member 210 is structured to move through the air with decreased drag resistance for increased swing speed. The aerodynamic shape of the first airfoil member 210 is tapered to allow for efficient airflow along and around the exterior surface 215 of the first airfoil member 210. The aerodynamic shape of the first airfoil member 210 may promote increased speed during transition of a swing from the initial downswing, through the perceived moment of impact with a golf ball, and / or follow-through of the swing. For example, airflow moving against the side of the weight tip 200 during the late downswing may disperse efficiently around the shape of the first airfoil member 210 which may result in increased swing speed.

[0031] The first airfoil member 210 has an elongated body 214 that may be tapered. The elongated body 214 may have a bulbous lead end 212 and a converging trail end 216. The bulbous lead end 212 may be convexly rounded and disposed adjacent the converging lead end 202 of the weight tip 200 towards the proximal end. The converging trail end 216 may be concavely rounded and disposed adjacent the bulbous trail end 206 of the weight tip towards the distal end 208. As a result, the elongated body 214 may be shaped like that of an elongated teardrop or a bullet on its face. A side profile or cross section of the first airfoil member 210 may be shaped like that of a wing. The shape of the first airfoil member 210 may be disposed in a position that is contrary or opposite in direction of the shape of the weight tip 200. Alternatively, the first airfoil member may be disposed in an inverse position that is contrary or opposite in direction as depicted by the first airfoil member 210 shown in FIG. 2.

[0032] The total weight of the swing speed trainer 100 may be customized by adjusting the mass of the weight tip 200. The weight tip 200 may be structured to receive a weight plug in a distal end of the swing speed trainer 100. A plurality of weight plugs 440 that are interchangeable with the weight tip 200 are shown in FIG. 5 and FIG. 7. The plurality of weight plugs 440 may be sold individually or as a set of weight plugs in a trainer kit. The plurality of weight plugs 440 allow for customization of the swing speed trainer 100 by what is referred to as an “inertia matching system.” The plurality of weight plugs 440 of the inertia matching system allow the swing speed trainer 100 to be specifically weighted relative to a golfer's personal driver, or other golf club. The ability to customize with interchangeable weight plugs allows a trainee 10 to adjust the total weight of the swing speed trainer 100 relative to the weight of their personal golf club to meet specific inertial weight protocols during overspeed training sessions.

[0033] Inertial effects on the swing speed trainer 100 may be maximized since interchangeable weight plugs may be received distally at the bulbous trail end 206 of the weight tip 200 as shown in FIG. 6. As a result, the central balance point of the swing speed trainer 100 may have a greater shift in weight towards the distal end for every gram of mass added to the weight tip 200.

[0034] The weight tip 200 may be structured to internally receive any of the plurality of weight plugs 440 from the bulbous trail end 206. As shown in FIG. 7, an internal cavity 400 that is hollow may be disposed in the bulbous trail end 206 of the weight tip 200 at the distal end 208. The internal cavity 400 may be structured to threadedly receive a specifically weighted plug that is complimentarily threaded.

[0035] As shown in FIG. 6, the first weight plug 410 is threadedly received and housed within the internal cavity 400 of the weight tip 200. Alternatively, the first weight plug 410 may be engaged with the internal cavity 400 by a press fitting, snap on, clasp, or by other fastening means. In one alternative example, the first weight plug 410 is pressed and secured into the internal cavity 400 by a friction fit. As shown in FIG. 3, a set screw 417 may be threadedly inserted through the rounded trail end 416 of the weight plug and secured to the distal end of the weight tip 200.

[0036] The first weight plug 410 may have a cylindrical body 414. The cylindrical body 414 may be threaded complementarily to be received by the internal cavity 400. The first weight plug 410 may have a rounded trail end 416 that is convexly curved. The rounded trail end 416 may be disposed at a distal end 418 of the first weight plug 410 that is opposite a threaded proximal end 412. The rounded trail end 416 may be structured to match a curvature of the bulbous trail end 206 of the weight tip 200 to form a low profile. The transition between the rounded trail end 416 and the annular rim 415 at the distal end 208 of the weight tip 200 may be flush when joined together. As a result, the rounded trail end 416 of the first weight plug 410 and the bulbous trail end 206 of the weight tip are shaped to slide across the ground with less friction or resistance should the swing speed trainer 100 contact the ground.

[0037] A screw drive slot 419 may be disposed in the rounded trail end 416 at a distal point aligned within a central longitudinal axis of the first weight plug 410. The screw drive slot 419 may be structured to rotate the first weight plug 410 in a clockwise and counterclockwise direction in operative cooperation with a complementary shaped screw bit. A manual or powered screwdriver or torque wrench may be utilized to interchangeably seat and unseat the first weight plug 410, a second weight plug 420, or a third weight plug 430 within the internal cavity 400 of the weight tip 200.

[0038] The plurality of weight plugs 440 may include a series of plugs having masses that are similar, different, or a combination of both. The weight plugs of the inertia matching system may range in mass between approximately 10 grams to 100 grams. The plurality of weight plugs 440 may comprise specifically weighted plugs with masses such as 20 grams, 22 grams, 30 grams, 40 grams, 44 grams, 80 grams, 88 grams, or other mass to customize the total weight of the swing speed trainer 100 relative to the total weight of the golfer's personal club.

[0039] The unplugged weight tips may range in mass between approximately 100 grams to 200 grams. The light club may be specifically weighted to have a relative weight variance of approximately 20% to 30% less than the total weight of a standard driver used by a golfer. The medium club may be specifically weighted to have a relative weight variance of approximately 1% to 20% less than the total weight of a standard driver used by a golfer. The heavy club may be specifically weighted to have a relative weight variance of approximately 1% to 25% more than the total weight of a standard driver used by a golfer.

[0040] In one example, the first swing trainer 110, the second swing trainer 120, and the third swing trainer 130 with unplugged weight tips may have initial total masses that are the same as one another. The initial total mass of each swing trainer may be approximately 220 grams. The trainee's personal driver may have a total mass of approximately 300 grams. Therefore, the trainee 10 may select from the inertia matching system a first weight plug 410 that is 20 grams in mass, a second weight plug 420 that is 50 grams in mass, and a third weight plug 430 that is 95 grams in mass. Plugging engagement of the first weight plug 410 into the weight tip of the first swing trainer 110 may correlate to a weight variance of approximately −20% relative to the trainee's personal driver. Plugging engagement of the second weight plug 420 into the weight tip of the second swing trainer 120 may correlate to a weight variance of approximately −10% relative to the trainee's personal driver. Plugging engagement of the third weight plug 430 into the weight tip of the third swing trainer 130 may correlate to a weight variance of approximately +5% relative to the trainee's personal driver.

[0041] In another example, the first swing trainer 110, the second swing trainer 120, and the third swing trainer 130 with unplugged weight tips may have initial total masses that are different from one another. The initial total mass of the first swing trainer 110, the second swing trainer 120, and the third swing trainer 130 may be approximately 210 grams, 240 grams, and 285 grams, respectively. The trainee's personal driver may have a total mass of approximately 300 grams. Therefore, the trainee 10 may select from the inertia matching system a first weight plug 410 that is 30 grams in mass, a second weight plug 420 that is 30 grams in mass, and a third weight plug 430 that is 30 grams in mass. Plugging engagement of the first weight plug 410 into the weight tip of the first swing trainer 110 may correlate to a weight variance of approximately −20% relative to the trainee's personal driver. Plugging engagement of the second weight plug 420 into the weight tip of the second swing trainer 120 may correlate to a weight variance of approximately −10% relative to the trainee's personal driver. Plugging engagement of the third weight plug 430 into the weight tip of the third swing trainer 130 may correlate to a weight variance of approximately +5% relative to the trainee's personal driver.

[0042] Alternatively, trainee 10 may utilize a single swing speed trainer 100 without the need for a plurality of swing speed trainers 1000. In this case, trainee 10 would customize the total weight of the single swing speed trainer 100 with the interchangeable weight plugs between practice swings during overspeed training.

[0043] As shown in FIG. 6, the converging lead end 202 of the weight tip 200 may be structured to receive a distal end 508 of the tapered shaft 500 of the swing speed trainer 100. Alternatively, the weight tip may be disposed inversely in a position that is contrary or opposite in direction as depicted by the weight tip 200 shown in FIG. 6. In this alternative, the bulbous end of the weight tip may be structured to receive the distal end 508 of the tapered shaft 500 of the swing speed trainer 100. As a result, the weight plug may be received distally in the converging end of the weight tip 200.

[0044] The diameter of the tapered shaft 500 gradually increases from the distal end 508 towards a proximal end 502. The material stiffness and diameter of the tapered shaft 500 may be structured with a specific shaft bend profile to support increased downswing loading, also referred to as “lag.” The shaft bend profile may vary from a butt section, through a mid-section, and to a tip section of the tapered shaft 500. Initial lag of the weight tip 200 and maximized release at the bottom of the downswing, which represents the perceived moment of impact with a golf ball, promotes improved feedback to trainee 10 on timing their release of an actual club head during a golf swing for distance and swing speed gains.

[0045] The tapered shaft 500 may be made of steel, aluminum, graphite, carbon fiber, synthetic or composite material structured to meet specifications of a selected shaft bend profile. In one example, the shaft bend profile selected provided a tapered shaft 500 with a butt section having a medium to high stiffness rating, a mid-section with a medium stiffness rating, and a tip section with a soft to medium stiffness rating. The stiffness rating, also known as the flex of the shaft, may be based on a frequency measurement in cycles per minute (cpm) of how many times the shaft oscillates. In this example, the tapered shaft 500 may have a stiffness rating of approximately 250 cpm to 300 cpm, or further between 285 cpm to 290 cpm.

[0046] The butt section or top portion of the tapered shaft 500, also referred to as the “load zone 504,” is disposed towards the proximal end 502 of the tapered shaft 500. The load zone 504 may be a stiffer area adjacent to a pressure grip 600. The load zone 504 is structured to promote storage of potential energy from initial downswing to mid- to late-downswing during transition of the golf swing sequence.

[0047] The tip section or bottom portion of the tapered shaft 500, also referred to as the “torque zone 506,” is disposed towards the distal end 508 of the tapered shaft 500. Torque zone 506 may be a more flexible area adjacent to the weight tip 200. The torque zone 506 is structured to promote release of potential energy from mid- to late-downswing to the perceived moment of impact with a golf ball at the bottom of the downswing during transition of the golf swing sequence.

[0048] An example of the pressure grip 600 is shown in FIG. 8. The pressure grip 600 may be sold individually or as a set of pressure grips in a trainer kit. The pressure grip 600 of the swing speed trainer 100 may receive and enclose the tapered shaft 500 at the proximal end 502 as shown in FIG. 9. The pressure grip 600 positively affects a trainee's athletic swing by activating specific muscles of the lead and trail hands which results in increased swing speed. The pressure grip 600 may be of a larger diameter than a grip of a golfer's personal driver to promote proper grip strength and pressure. The pressure grip 600 may have a multi-textured surface to promote proper grip strength and pressure.

[0049] Alternating compression and decompression zones are disposed on the pressure grip 600. The alternating compression and decompression zones may interact with specific digits or portions of the hands of the trainee 10 to direct varied grip pressures. Interaction with a plurality of textures of the pressure grip 600 by trainee 10 may promote an appropriate amount of grip strength and pressure to increase trainee's swing speed.

[0050] A first compression zone 610 may be disposed within a proximal section of the pressure grip 600. The first compression zone 610 of the pressure grip 600 may have a pad layer 612 that is smooth and soft. The pad layer 612 may provide a cushioning effect to cause the trainee 10 to apply more grip pressure at the first compression zone 610. The pad layer 612 may be made of a low resilient material, such as rubber, synthetic, or a composite material, which is structured with a lower density to give greater pliability when in contact with a trainee's hand. The pliability of the material may be based on a factor of compression. The first compression zone 610 may have low resistance during movement between the pad layer 612 and the trainee's skin.

[0051] The first compression zone 610 may reside within a first grip position 615 made by trainee 10. Placement of a proximal portion 13 of the lead hand 12 by trainee 10 may correlate to the location of the first compression zone 610 disposed on the pressure grip 600. The proximal portion 13 may comprise the three proximal digits of the lead hand 12, that is, the middle, ring, and little fingers. The pad layer 612 may be structured to prompt trainee 10 to increase grip pressure by the proximal portion 13 of the lead hand 12 upon the pressure grip 600 within the first compression zone 610.

[0052] A first decompression zone 620 may be disposed within the mid-proximal section of the pressure grip 600. The first decompression zone 620 of the pressure grip 600 may have a stiff layer 622 that is textured and stiff. The stiff layer 622 may provide unpadded support and resistance to cause the trainee 10 to apply less grip pressure to the first decompression zone 620. The stiff layer 622 may be made of a high resilient material, such as rubber, synthetic, or composite material, which is structured with higher density to give greater resilience when in contact with a trainee's hand. The resilience of the material may be based on a factor of firmness. The first decompression zone 620 may have high resistance during movement between the stiff layer 622 and the trainee's skin.

[0053] The first decompression zone 620 may reside partly within the first grip position 615 and partly within a second grip position 625 made by trainee 10. Placement of a distal portion 14 of the lead hand 12 and a proximal portion 17 of the trail hand 16 by trainee 10 may correlate to the location of the first decompression zone 620 disposed on the pressure grip 600. The distal portion 14 may comprise the two distal digits of the lead hand 12, that is, the thumb and index fingers. The proximal portion 17 may comprise the three proximal digits of the trail hand 16, that is, the middle, ring, and little fingers. The stiff layer 622 may be structured to prompt trainee 10 to decrease grip pressure by the distal portion 14 of the lead hand 12 and the proximal portion 17 of the trail hand 16 upon the pressure grip 600 within the first decompression zone 620. The first decompression zone 620 may be disposed between the first compression zone 610 and a second compression zone 630.

[0054] The second compression zone 630 may be disposed within a mid-distal section of the pressure grip 600. The second compression zone 630 of the pressure grip 600 may have a pad layer 632 that is smooth and soft. The pad layer 632 may provide a cushioning effect to cause the trainee 10 to apply more grip pressure to the second compression zone 630. The pad layer may 632 be made of a low resilient material that is structured with lower density to give greater pliability when in contact with trainee's hand. The pliability of the material may be based on a factor of compression. The second compression zone 630 may have low resistance during movement between the pad layer 632 and the trainee's skin.

[0055] The second compression zone 630 may reside within the second grip position 625 made by the trainee 10. Placement of a distal portion 18 of the trail hand 16 by trainee 10 may correlate to the location of the second compression zone 630 disposed on the pressure grip 600. The distal portion 18 may comprise the two distal digits of the trail hand 16, that is, the thumb and index fingers. The pad layer 632 may be structured to prompt trainee 10 to increase grip pressure by the distal portion 18 of the trail hand 16 upon the pressure grip 600 within the second compression zone 630. The second compression zone 630 may be disposed between the first decompression zone 620 and a second decompression zone 640.

[0056] The second decompression zone 640 may be disposed on the distal section of the pressure grip 600. The second decompression zone 640 of the pressure grip 600 may have a stiff layer 642 that is textured and stiff. The stiff layer 642 may provide unpadded support and resistance to cause the trainee 10 to apply less grip pressure to the second decompression zone 640. The stiff layer 642 may be made of a high resilient material that is structured with higher density to give greater resilience when in contact with a trainee's hand. The resilience of the material may be based on a factor of firmness. The second decompression zone 640 may have high resistance during movement between the stiff layer 642 and the trainee's skin. The stiff layer 642 may be structured to prompt trainee 10 to decrease grip pressure upon the pressure grip 600 within the second decompression zone 640. The second decompression zone 640 may reside adjacent to the second grip position 625 made by trainee 10.
