Swing trainer

Abstract

A swing trainer configured to draw the elbows of the player together by the cocking of the player's wrists. The swing trainer includes arm mounts configured to mount to a player's arms at an intermediate position; and a link with at least a portion connected to the mounts and extending therebetween and arranged such that the portion of the link between the arms is configured to shorten during a swing of a stroke to inhibit splaying of the elbows of the player during the stroke, the link being slidably connected to the one of the mounts so it may slide past. A corresponding method of swing training using said swing trainer is also disclosed.

DETAILED DESCRIPTION OF AN EXAMPLE EMBODIMENT

(13) Referring to the drawings there is shown a first embodiment of swing trainer generally indicated at 10. The swing trainer 10 includes a golf club mount 20, and two arm mounts 30 and 40 which are configured, as shown in FIG. 1, to fasten to the arms of a user, generally in the position of the elbows, or as close to the elbows as is comfortable during a swing. It should be noted that in use, the elbows should be at least slightly free to hinge.

(14) The swing trainer 10 also includes a flexible connector assembly 50, which may be resilient so as to form a resilient connector assembly 51 to facilitate a gentler and more ergonomic stop when the arms are drawn together during the end of the backstroke. The resilient connector assembly 51 is fastened to the golf club mount at one end 53 and to the one or more arm mounts 30 and 40 using receivers or catches shown at 52 so that the arms in use are linked to each other and to the golf head. The resilient connector is a flexible line 54, which may be in the form of an elastic rope or cord 55, such as may be seen in an octopus strap, for convenience of manufacture, light mass, durability and/or use.

(15) The golf club mount 20 includes an anchor 22 which includes a threaded spike 24 to facilitate its fastening or mounting to the club end. Usually the club end includes a rubberised grip over a hollow club shaft, to which the threaded spike 24 may fasten. The threaded spike 24 may also “start” in a hole provided in the rubberised grip handle.

(16) The golf club mount 20 also includes a plate 23 on which an articulating joint 26 is mounted, the articulating joint 26 being in the form of a ball and socket joint 28 so as to facilitate free rotation of the end of the club in relation to the resilient connector assembly during a cock of the wrist, which occurs during at least the top portion of the backswing.

(17) The golf club mount 20 may also include a receiver or catch 21 to receive the resilient line 54. The receiver or catch 21 may be in the form of a hook or an eye 25 or some suitable receiver element to facilitate tying to, looping through, or swaging to, or other fastening device.

(18) The arm mounts 30 and 40 are in the form of cuffs or sleeves 31, 41, to facilitate fastening to the arm, each one at a suitable location, such as respective elbows. The cuffs 31, 41 are straps 35, 45 made of webbing or other broad and strong textile, lined with foam 37, 47 for additional comfort. The cuffs 31, 41 also include hook and loop strap fasteners 39, 49, and a buckle so as to close the webbing straps around the arms in a variable manner, to suit various arm diameters. The arm mounts 30 and 40 are in the form of a leg or arm leash mount for a surfboard or body board, for ease of use. They are hook-and-loop-fastened cuffs.

(19) The arm mounts 30, 40 also include one or more receivers or catches 32, 42 to receive the resilient line 54. The receiver 32 is an eye 33 so as to provide sliding connection between the flexible line 54 and the arm mount 30, while being configured to pull in a direction normal to the arm mount 30, to draw the elbow in, in use. The receiver 42 is an anchor 43 so as to anchor the other end of the flexible line 54 on the arm mount 40.

(20) The receiver 32 and 42 are mounted on swivels, to facilitate free flow of the line 54 through the eye 33. The receivers or catches may also include ball and socket joints or other articulated joints for free movement of the line through the eye 33.

(21) The swing trainer 10 includes a tensioner 60 to tension or shorten the flexible line 54. The tensioner 60 is the anchor 43 with a lock 62 to inhibit the resilient connector passing through the eye 61. The lock 62 is a rotating closure 63 and a collet, which in use screws down and closes the eye, to promote ergonomic use of the lock. The lock may be a cleat in the form of a jam cleat or other kind of one-way cleat.

(22) FIG. 6 shows a section view in which it can be seen that the receiver 32 and 42 are both anchored to the arm mounts 30 and 40 by having a broad anchor portion 99 inhibiting pulling through the arm mounts.

(23) FIGS. 7 to 10 show another embodiment of the swing trainer, generally indicated at 100. In the Figures, for efficiency of description, structures like those in FIGS. 1 to 6 are indicated with like numerals, such as 10, 100, and 20, 120 and so on.

(24) Therefore, it can be seen that arm mounts 130 and 140 are shown, which are linked with flexible link 154 which extends from one end 142, through the eye 133 of arm mount 130 and on, when in a donned position on the player, along the right arm (of a right-handed player) to be releasably connectable via clip 198 to the eye 125 of a golf club mount 120.

(25) The flexible line 154 assembly 150 includes a tensioner 160 which tensions or shortens in use, the flexible line 154 by twisting the clutch 170. The clutch 170 includes a pair of posts 171 which cause the flexible line 154 to extend through the clutch body 172 on a tortuous path. The path can be opened up by twisting the clutch body 172 and allowing the clutch body 172 to slide along the flexible line 154 to shorten the line 154 to a suitable length.

(26) The clip 198 allows the player to change clubs to suit the distance of the shot desired to be played.

(27) In operation a user dons the arm mounts 30, 40 or 130, 140 by fastening them to his or her arms, near the elbows, as shown in FIG. 1. The user then attaches the golf club mount 20, 120 to the head end of the golf club. At this time, it can be seen from FIG. 1 that the resilient line 54, 154 runs from the head end of the club, for a right-handed player, along the right arm to the elbow, and then across to the left elbow. The line 54, 154 is guided by the eye 33, 133 but can slide freely therethrough, so that the elbows may be drawn together during operation of the swing trainer 10, 110. The line 54 is anchored at the other end to arm mount 40, 140. Of course, it is to be understood that the line 54 may run along the left arm to the elbow from the head end of the club, for left-handed players.

(28) The tensioner 60, 160, is tensioned to an appropriate level by drawing the line 54 through the eye 61 and locked off by the lock 62, or in the case of line 154, by twisting the clutch body 170 and drawing it along the line 154. An appropriate level of tension is such that there is a triangle allowed as shown in FIG. 1, when addressing the ball with the club, and when forming the triangle, there is not much tension in the line 54, but the line 54 is not loose. Finger tight, say.

(29) The user, in use, swings the club from the position shown in FIG. 1, the address, to the back of the backswing, and finds that the elbows are constrained by the line 54. Once the wrist is cocked, usually at the top of the backswing, but sometimes before, the player feels strongly the elbow constraint, and the elbows are given an extra tension force, and pull inward toward one another, then during wearing of the trainer, and after, the player remembers that feeling and releases on the downstroke, without flaring the elbows during the stroke.

(30) It can be understood from the drawings and description hereinbefore that the further down the club grip the player holds the club, the longer a lever arm that the end of the club makes between the player's hands and the club anchor 20, 120, and the more striking the inward drawing of the elbows will be, and be felt.

(31) In use, the player extends a line between the elbows and down one arm to the club head so that by cocking the wrist, the club head draws the elbows of the player inward.

(32) Clarifications
