Wrist position training device for a sports swing

Abstract

A wrist position training device for a sport swing includes one or more wrist wraps to secure a haptic member to the back of a user's wrist and hand. A first end of the haptic member is anchored to the user's forearm. A second end of the haptic member is secured to the back of the user's hand by a finger loop or similar structure so that the haptic member follows the user's hand as the wrist transitions from a neutral position to a flexion position. The haptic member produces a tactile and audible response when transitioning between the neutral and flexion positions. This tactile and audible response signals to the user when their wrist breaks and returns to neutral position.

DETAILED DESCRIPTION

(17) The present invention is a wrist position training device for a sports swing, in particular a golf swing, generally referred to by reference numeral 20 in FIGS. 1-10B. At a minimum, the training device 20 includes a haptic member 22, a wrist wrap 24 at one end, and an anchor loop 26 at the opposite end. While the following description is particularly focused on the sport of golf and a golf swing, the inventive training device can be used in any sport or other context where training proper wrist positioning and knowing when a user's wrist transitions to and from flexion is important.

(18) The haptic member 22 preferably has an elongated rectangular shape with a first end 22a and a second end 22b along the long dimension of the rectangle, also having an upper surface 22c and a lower surface 22d. The haptic member 22 is configured to maintain a generally planar shape in what is referred to as a neutral or default position (FIGS. 7 and 10A). In the neutral or default position, the haptic member 22 is generally linear or straight and configured to be rigid or semi-rigid along its length such that it will not deform unless subjected to a predetermined minimum threshold of force. The minimum threshold of force is not substantial—just enough to maintain the haptic member 22 straight unless subjected to a deflection force. Once the deflection force is removed, the haptic member 22 returns to the neutral or default position.

(19) Inside the haptic member 22 is a thin, elongated piece of metal or plastic (not shown). The piece of metal or plastic preferably has a slight lateral curvature forming a slight concavity between the side edges, so as to resemble a tape measure or material of similar configuration. This concavity in the piece of metal or plastic preferably extends longitudinally along the entire haptic member 22. The piece of metal or plastic is generally configured having a short length, i.e., about 4-6 inches.

(20) The haptic member 22 is configured to be resiliently flexible in either an upward direction, i.e., such that the upper surface 22c forms a slight internal arc along its length, or a downward direction, i.e., such that the lower surface 22d forms a slight internal arc along its length. When bent in an upward direction, the haptic member 22 is configured such that it produces only a slight physical release. The haptic member 22 is configured to easily bend in an upward direction with little to no haptic response. Conversely, when bent in a downward direction (FIGS. 8 and 10B), the haptic member 22 is configured such that it produces a sudden physical release creating a significant haptic response, including both a physical signal and an audible signal—a “click”. The haptic member 22 produces the same haptic response when it resiles or resiliently returns to the neutral or default position (FIGS. 7 and 10A) from the bent downward position (FIGS. 8 and 10B).

(21) The wrist wrap 24 is attached proximate to the first end 22a of the haptic member 22 and is preferably attached to the upper surface 22c of the haptic member 22. However, it may also be attached to the lower surface 22d thereof but would be less secure in that configuration. The wrist wrap 24 is configured to encircle the lower surface 22d of the haptic member 22 and secure a free end 24a of the wrist wrap 24 to a portion of itself attached to the haptic member 22. In particular, the wrist wrap 24 is configured to wrap around a user's wrist (FIGS. 7-10B) when the training device 20 is being worn, as described below.

(22) The wrist wrap 24 preferably has a hook-and-loop or similarly adjustable connection so that it can be snuggly applied, possibly including a securing ring or bracket 24b or similar slide structure that facilitates securing a tighter fit. By using the securing ring 24b, a user may more easily apply and tightly secure the wrist wrap 24 to their wrist by passing the free end 24a of the wrist wrap 24 through the securing ring 24b, folding the free end 24a back along the wrist wrap 24 and securing the same to a portion of the wrist wrap 24. Such mechanisms for securing similar structures are known in the art, as by using hook-and-loop or similar fasteners. When properly and tightly secured, the wrist wrap 24 is configured to hold the haptic member 22 on top of a user's wrist and hand without significant lateral or longitudinal movement.

(23) An anchor loop 26 is attached to the second end 22b of the haptic member 22. The anchor loop 26 preferably comprises a looped length of cord, rope or similar material that extends from the second end 22b. The anchor loop 26 is configured to encircle one or more of a user's fingers—preferably at least the middle finger—when the device 20 is worn by a user. When properly worn and configured, the anchor loop 26 secures the second end 22b of the haptic member 22 to the back of a user's hand such that the haptic member 22 stays against the back of the hand throughout any downward bending of the wrist.

(24) The anchor loop 26 may also include an adjustment ring 26a so that the length of the anchor loop 26 can be adjusted to accommodate users with hands of different sizes. The adjustment ring 26a preferably includes a friction stop 26b that is slidable within the adjustment ring 26a, so as to selectively hold or release the anchor loop 26. In addition, the anchor loop 26 preferably includes a retention stop 26c attached to the lower surface 22d of the haptic member 22, so that the anchor loop 26 is prevented from being pulled completely inside of the haptic member 22 during any adjustments.

(25) The training device preferably also includes a spacing pad 30 attached to the lower surface 22d of the haptic member 22. The spacing pad 30 is configured to be disposed between the lower surface 22d and the back of the user's wrist and hand. The function of the spacing pad 30 is to slightly elevate a portion of the haptic member 22 relative to the user's wrist and hand, so as to increase the sensitivity of the haptic member 22 when the same is bent to and from a downward position as described more fully below. The spacing pad 30 preferably includes one or more rubberized ribs 30a on the underside of the spacing pad 30. The rubberized ribs 30a some air gaps between the spacing pad 30 and the user's wrist and hand, as well as prevent the spacing pad from slipping across the user's wrist and hand.

(26) In a first preferred embodiment, shown in FIGS. 1-10B, the training device 20 preferably includes an anchor wrap 28 adjacent to the wrist wrap 24. The anchor wrap 28 is preferably attached immediately adjacent to the wrist wrap 24, at the very end of the first end 22a of the haptic member 22, attached to the upper surface 22c of the haptic member 22. The anchor wrap 28 is preferably configured to encircle the lower surface 22d of the haptic member 22 and secure a free end 28a of the anchor wrap 28 to a portion of itself adjacent the haptic member 22. Having the anchor wrap 28 separate from the wrist wrap 24 allows a user to apply different amounts of tightness to each wrap 24, 28 around the user's wrist depending on the preferred comfort and to account for different sizes of users.

(27) In particular, the anchor wrap 28 is configured to wrap around a portion of a user's forearm near to the wrist (FIGS. 7-10B) when the training device 20 is being worn, as described below. The anchor wrap 28 is configured to securely hold the first end 22a of the haptic member 22 against the top of a user's forearm with little to no flexibility. As described below, in the operation of the training device 20, it is important that the first end 22a of the haptic member 22 does not move away from the top of a user's forearm. As shown in FIG. 9, without the anchor strap 28 secured, the first end 22a of the haptic member 22 is permitted to lift away from the user's forearm. The separation of lifting away of the first end 22a from the user's forearm is likely to lessen the responsiveness of the haptic member 22.

(28) In addition, in the first preferred embodiment, the spacing pad 30 preferably has an elongated rectangular shape similar to the haptic member 22. The spacing pad 30 in this embodiment is preferably about half the length of the haptic member 22, such that one end of the spacing pad 30 extends slightly from under the wrist wrap 24. This extension of the spacing pad 30 from under the wrist wrap 24 moves a breaking point of the haptic member 22 when transitioning from the neutral position (FIGS. 7 and 10A) to the bent downward position (FIGS. 8 and 10B), as explained below

(29) In a second preferred embodiment of the training device 40, shown in FIGS. 11-14, the wrist wrap 42 has a similar configuration as but is wider than wrist wrap 24 of the first preferred embodiment. The wrist wrap 42 also has a free end 42a and a securing ring 42b. By making the wrist wrap 42 wider, it provides the additional securing function of the anchor wrap 28 of the first preferred embodiment without having the separate anchor strap 28. This makes it so a user is only required to secure one strap—not two—when wearing the training device 40. In addition, in the second preferred embodiment, the spacing pad 44 has a general wedge shape as opposed to the elongated rectangular shape of the spacing pad 30 in the first preferred embodiment. This wedge shape of the spacing pad 44 has a broad end 46 and a narrow end 48. When the spacing pad 44 is positioned under the haptic member 22, the broad end 46 is preferably oriented toward the user's hand and the narrow end 48 is preferably oriented toward the user's forearm. The broad end 46 slightly elevates the second end 22b of the haptic member 22 above the wrist and hand so as to alter the break angle of the same. The relative orientations of the broad end 48 and narrow end 48 of the spacing pad 44 position the haptic member 22 as having a slight upward angle relative to the user's wrist and hand.

(30) In either the first or second embodiment, the gap created by the spacing pad 30 ,44 is designed to position second end 22b of the haptic member 22 over and above the back of the user's hand. The spacing pad 30, 44 may have a uniform thickness so that the brace member 14 extends generally parallel to the user's wrist and forearm when in a neutral position. Alternatively, if the spacing pad 44 has a wedge shape with the broad end 46 oriented toward the user's hand, the second end 22b of the haptic member 22 is elevated over and above the back of the user's hand to a greater extent. The degree of slope in the spacing pad 30, 44 can greatly alter the angle at which the second end 22b is elevated.

(31) In either embodiment, the training device 20, 40 is configured to be worn on the wrist of a user, particularly the leading or forward wrist in a golf swing. The haptic member 22 is preferably positioned along the back of the user's wrist and hand—the first end 22a positioned proximate to the wrist and the second end 22b positioned proximate to the knuckles on the user's hand. The wrist wrap 24, 42 is configured to securely hold the training device 20, 40 on the wrist of the user. The wrist wrap 24, 42 should be positioned at or immediately behind the wrist joint so that the user's hand can hinge without interference. When included, the anchor wrap 28 may separately secure the first end 22a of the haptic member 22 to the user's forearm. The anchor loop 26 is then secured to a user's finger, preferably the middle finger but ideally whichever finger keeps the haptic member 22 aligned with the user's wrist and forearm.

(32) The anchor loop 26 should be sufficiently tightened so as to keep the second end 22b of the haptic member 22 close to the back of the user's hand, even when the wrist is moved into flexion, i.e., the hand bent downward relative to the forearm. With the hand/wrist in flexion, the tension on the anchor loop 26 bends the second end 22b of the haptic member 22 downward following the user's hand. As described above, when the haptic member 22 is bent downward—transitioning from the neutral position to the bent downward position—it produces a significant haptic response, including both a physical signal and an audible signal—a “click”. The haptic member 22 produces the same haptic response when it resiles or resiliently returns to the neutral position from the bent downward position.

(33) When training a golf swing (or other sports swing) it is often helpful to provide this type of signaling or feedback so that a user can better determine where in the arc of the swing their wrist “breaks”, i.e., when their wrist moves into and out of flexion. Oftentimes, a human swing trainer can watch a user's golf swing a correct the wrist position based on visual observations. However, a user working on their own, does not have a swing trainer to watch their swing and tell them what to change. The individual user must keep their eyes on the ball rather than watch their wrists. Given the speed of a swing, an individual user cannot tell based solely on proprioception or muscle sensation with enough certainty where the wrist break occurs. The significant haptic response of the haptic member 22 emphasizes wherein the swing arc the wrist breaks without visual observation.

(34) Because the haptic member 22 produces the haptic response both when bending from neutral to bent downward positions and from bent downward to neutral positions, the training device 20, 40 provides feedback during the backswing, the downswing, and through the point of impact. In particular, the haptic response through the point of impact lets the user better understand the orientation of the wrist when the club or bat hits the ball. In golf, this is important as the angle of the wrist translates directly into the angle of the club face at the point of impact with the golf ball, particularly considering the length of golf clubs and the distance of the club head from the user's hands. If the angle of the club face is off by even a few degrees, the ball is likely take off at an undesirable angle and/or loft, altering the ball trajectory costing the user significant distance and/or direction.

(35) The training device 20, 40 may also be used on the trailing hand of a user to again indicate where in the arc of the swing the user's trailing hand “breaks” or transitions from neutral to bent downward. In the context of a sports swing, for a right-handed athlete, leading hand refers to the left hand—for a left-handed athlete, leading hand refers to the right hand. Conversely, for a right-handed athlete, trailing hand refers to the right hand—for a left-handed athlete, trailing hand refers to the left hand.

(36) When a user applies sufficient force by breaking the wrist, i.e., flexion, the haptic member 22 transitions from the neutral position to the bent downward or functional position. In this transition, the haptic member 22 makes an audible and tactile “click” to alert the user of the transition. This audible and tactile “click” is designed to inform the user that the wrist is in the proper flexion position. When adjusted to a proper length, the anchor loop 26 also helps guide the user to avoid over-flexion of the wrist, i.e., bending the wrist too far.

(37) Because the haptic member 22 snaps back to the neutral position when a deflecting force is removed, the training device 20, 40 also alerts the user if sufficient flexion is removed from the wrist too early at any point in the swing. Thus, when being used for example in a golf swing, the user has his or her wrist in a neutral position at address. Approaching the top of the backswing, the wrist on the user's leading hand breaks slightly, causing the haptic member 22 to “click”. Because of this “click” and the tension from the anchor loop 26, the user knows that his or her wrist has the correct degree of flexion for impact to ensure a club face squared to the swing arc. Throughout the downswing to impact, the user attempts to maintain this degree of flexion. If at any point in the down swing the haptic member 22 “clicks” again, prior to impact, the user will know that the degree of flexion has lessened and the club face is likely not in the proper position, i.e., square to the swing arc.

(38) If the swing is performed correctly, with the correct degree of flexion in the wrist, the club face with impact the ball squarely and the haptic member 22 will “click” in response to a return to the neutral position only after impact. In this way, the training aid 10 provides positive reinforcement to alert the user when his or her hands and wrist are in the proper position. This is contrasted with other known prior art training aids, particularly wrist trainers, that provide negative reinforcement, i.e., alert the golfer only when the wrist is in an improper position.

(39) Although several embodiments have been described in detail for purposes of illustration, various modifications may be made without departing from the scope and spirit of the invention.
