Definitions

  • the present invention relates to a golfing aid and, more particularly, to an apparatus for alerting a golfer to movement of the golfer's head during a golf swing.
  • a golfer At the address position, a golfer is ideally standing with his/her feet placed comfortably apart and bending slightly from the waist towards the ball with his/her back straight and his/her head comfortably positioned in line with his/her spine.
  • upper body movement comprises rotation about the axis of the spine.
  • the golfer's head During the back swing, down swing and striking of the ball, the golfer's head ideally remains stationary with the remainder of the upper body effectively rotating about the axis of the spine below the head.
  • the golfer's head after striking of the ball, the golfer's head remains stationary with his/her upper body again rotating about the axis of the spine during the follow through until a point is reached where movement of the head is required to enable the upper body to complete the follow through stage of the swing.
  • the head ideally follows the movement of the remainder of the upper body by also rotating about the axis of the spine and thereby maintaining the centre of the swing arc fixed. That is to say that it is undesirable if movement of the head at that point in the golf swing results in a tilting of the head with respect to the axis of the golfer's spine and hence translation of the centre of the swing arc.
  • the present invention provides an apparatus for alerting a golfer to movement of the golfer's head during a golf swing, the apparatus comprising detection means arranged to be secured to the golfer's head and detect movement of the golfer's head during the golf swing and alarm means arranged to receive a signal from the detection means when movement of the golfer's head is detected by the detection means.
  • the detection means can be arranged to detect various movements of the golfer's head.
  • the detection means can be arranged to detect undesirable tilting of the golfer's head (with consequential translation of the centre of the swing arc) at various points during the golf swing with the alarm means then instantaneously alerting the golfer to the problem.
  • the present invention can be used for alerting a golfer to a problem during his/her swing but preferably, the apparatus is arranged to alert the golfer when desirable movement of the golfer's head has occurred and thereby provide positive reinforcement to the golfer.
  • the detection means is arranged to detect rotation of the golfer's head about the axis of the golfer's spine and more preferably, the detection means is arranged to provide a signal to the alarm means at a point during the follow through of the golfer's swing.
  • the detection means comprises a mercury switch; however, it is to be understood that any other detection means which can be secured to a golfer's head and detect movement of the golfer's head during a golf swing can be utilised.
  • the detection means may comprise a track along which a metallic ball can roll, a spring arranged to bend during movement of the golfer's head, or a pendulum which swings during movement of the golfer's head.
  • the detection means is located in an apparatus worn by the golfer in a manner analogous to a headset of the kind used for listening to music or a pair of ear muffs.
  • the detection means is housed in an ear-piece assembly having an ear plug which is arranged to be located in an ear of the golfer.
  • the alarm means is arranged to receive a signal from the detection means when movement of the golfer's head is detected by the detection means.
  • the signal may take the form of an infrared signal or the like in which case the alarm means need not be physically connected to the detection means.
  • the alarm means is electrically connected to the detection means.
  • the alarm means may be configured to alert the golfer that the detection means has detected movement of the golfer's head in various ways.
  • the alarm means may be caused to vibrate in contact with a portion of the golfer's body or to produce a light which can be observed by the golfer during the swing.
  • the alarm means is arranged to emit a tone which is audible to the golfer on receipt of a signal from the detection means and in such case the alarm means preferably includes a source of power in the form of a battery and a buzzer.

  • Figure 1 illustrates a golfer subsequent to striking the golf ball at an early point of the follow through stage of the golf swing from which it can be noticed that the golfer's head remains fixed in the position of the address position and is perpendicular to the horizontal.
  • Figure 2 illustrates a subsequent point in the follow through at which the golfer's head has rotated about his spine through angle o. with the horizontal and it is such movement to which the golfer is preferably alerted during the golf swing by the present invention. It is to be noted that although the golfer's head has rotated, it has not tilted with respect to the axis of his spine and at the point illustrated in
  • the angle en may vary slightly between different golfers but will typically be in the order of 30°-40°.
  • the detection means preferably comprises a mercury switch 10 having a base 12 and two contacts 14 which penetrate through and project from its top 16.
  • the mercury switch 10 is coaxially housed within an ear-piece assembly 18 comprising a first body portion 20 and a second body portion 22 which are secured together by pegs 24 in the first body portion and corresponding recesses 26 in the second body portion.
  • the first body portion 20 is formed with a protrusion 28 which is arranged to receive a plug 30 suitable for insertion into a golfer's ear.
  • the mercury switch 10 is located within recesses 32 and 34 in the first and second body portions 20 and 22 respectively with the base 12 of mercury switch 10 sitting in recess 34.
  • the first body portion 20 is of a bent configuration with the result that when the detection means is assembled and the plug 30 is placed in the golfer's ear with the second body portion 22 lowermost, mercury 37 sits lowermost within the mercury switch 10 and remote from the contacts 14 as illustrated in Figure 9.
  • the angle ⁇ between the axis of the mercury switch 10 and the horizontal will typically be in the order of 30°-40° and, although not illustrated, it is to be noted that the angle could be varied to suit individual golfers by arranging housing of the mercury switch 10 within the assembly 18 such that the axis of the mercury switch 10 was variable with respect to the axis of the assembly 18, for example, by mounting the mercury switch 10 on an axle. Rotation of the golfer's head from the point illustrated in Figure 1 to the point illustrated in Figure 2 causes the mercury switch 10 to move from the position illustrated in Figure 9 to that illustrated in Figure 10 with consequential closing of the mercury switch 10 by virtue of the mercury 37 providing electrical conduction between contacts 14.
  • the closing of the mercury switch 10 completes an electric circuit with the alarm means (not shown) , thereby sending a signal to the alarm means (not shown) which emits a tone which is audible to the golfer.
  • the alarm means (not shown) may be clipped to the golfer's belt, hang around the golfer's neck, sit within the golfer's pocket or the like and will include a battery and a buzzer. It is to be noted that the embodiment described above can be used by either left-handed or right-handed golfers.
  • the plug 30 of the ear-piece assembly 18 will be placed in the golfer's left ear and in the case of a left-handed golfer, the plug 30 of the ear-piece assembly 18 will be placed in the golfer's right ear.
  • a right-handed golfer places the plug 30 of the ear-piece assembly 18 in his/her left ear with the second body portion 22 pointing towards the ground.
  • the golfer will not hear a tone from the alarm means until the back swing, down swing and striking of the ball have been completed and his/her head has rotated sufficiently about the axis of his/her spine for the mercury switch 10 to have been moved to a point where its axis passes through the horizontal and allows the mercury 37 to form an electrical bridge between the contacts 14. Accordingly, the golfer will not hear a tone until this point has been reached even if he/she lifts his/her head during striking of the ball or following through.
  • the apparatus takes the form of a headset 38 having ear-pieces 40 and 42 which are connected by a frame 44 and which are arranged to sit adjacent the golfer's ears (not shown).
  • a mercury switch 10 is located in ear-piece 40 and is electrically connected by wires 46 to alarm means 48 located in ear-piece 42.
  • the alarm means 48 includes a buzzer 50, a battery 52, an on-off switch 54 and a volume controller 56 for the buzzer 50.
  • the apparatus functions in the same manner as the embodiment described above. Accordingly, for a right-handed golfer the headset 38 will be worn with ear-pieces 40 and 42 adjacent the golfer's left and right ears respectively with the positioning of the ear-pieces reversed for a left-handed golfer.
  • ear-piece 40 may include a second mercury switch 10A with both mercury switches 10 and 10A wired to alarm means 48 in parallel as illustrated in Figure 12 with the advantage that ear-pieces 40 and 42 can be positioned adjacent either ear irrespective of whether the golfer is left-handed or right-handed.
  • the angle ⁇ between the axis of the mercury switch 10 or 10A and the horizontal can be varied to suit individual golfers by movement of ear-piece 40 relative to frame 44.

Abstract

La présente invention concerne un appareil permettant d'attirer l'attention des golfeurs sur le mouvement de leur tête effectué pendant un swing de golf. Cet appareil se compose d'un détecteur de mouvement (10, 10A) fixé à la tête des golfeurs et délivrant un signal à un dispositif de signalisation (48) en réaction au mouvement de tête. Ce détecteur de mouvement (10, 10A), qui est un interrupteur à mercure (10, 10A) disposé dans une oreillette (40) ou un casque d'écoute (38) porté par le golfeur, permet en l'occurrence de détecter l'inclinaison ou le relèvement de la tête pendant le swing de golf. Le dispositif de signalisation (48) délivre un son audible produit par un ronfleur (50) qui se fait entendre juste après le swing de golf. Le dispositif comporte un réglage de volume sonore (56) du ronfleur. Une autre signalisation peut être mise à la disposition du golfeur sous forme lumineuse ou vibratoire.
