GOLF TRAINING DEVICE

Abstract

A golf training device for use in a glove or under the ball of the foot or under the heel, which includes pressure sensors, a visual display which is flexibly connected to the sensors for adjusting the position to suit the wearer, and a controller programmed to provide visual feedback to indicate if the pressure is appropriate or not. For a glove the sensors are located on the palm at the junction with the first three fmgers. There are two or more sensors and for each sensor the controller can display by an appropriately coloured LED that the pressure detected by the sensor is too light, appropriate or too tight. For a shoe the sensors are located under the ball of the foot or the heel and the LEDs indicate whether the weight is appropriately on the ball of the foot or on the heel.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0017] A preferred embodiment of the invention will now be described with reference to the drawings in which:

[0018] FIG. 1 is a schematic view of a first embodiment sensor unit and display used in this invention;

[0019] FIG. 2 is a view of the location of the unit shown in FIG. 1 with the sensors positioned in a glove adjacent the junction of the palm and the fingers;

[0020] FIG. 3 shows the position of a second embodiment of the sensor unit positioned on the ball of the foot;

[0021] FIG. 4 shows the position of a second embodiment of the sensor unit positioned on the heel of the foot;

[0022] FIG. 5 is a view of the back of a glove showing the electronics PCB and the LED's on the glove fastening flap;

[0023] FIG. 6 is a view of a shoe showing the electronics PCB and the LED's positioned on the laces of shoe;

[0024] FIG. 7 is a view of a shoe showing the electronics PCB and the LED's positioned on the toe of shoe.

[0025] The preferred sensor unit as shown in FIG. 1 is a combination of Low Level Antistatic Electrically Conductive Film (Velostat) and a flexible PCB. The other alternative is using 2 FSR's (force sensing resistors).

[0026] The preferred sensor is built by using a combination of a layer of flexible PCB on top, then 1 layer of velostat, then another layer of velostat, then another flexible PCB, all enclosed in a fabric sleeve and the sleeve 11 is then sewn onto the inside palm of the glove running just above the lifeline crease on the palm.

[0027] The electronic components are two sensors connected to a micro controller which is programmed to provide power to the LEDs when the pressure signals from each sensor are above a threshold value, in a desired range, or above the desired range. For sensing foot pressure 4 sensing points are preferably used.

[0028] The PCB also includes a battery and a USB and a charging LED indicator.

[0029] The glove 20 as shown in FIGS. 2 and 5 consists of a pocket 11 sewn on the inside of the glove that houses the 2 sensors 12 which are placed strategically so that when the glove wearer holds the club correctly the 2 sensors detect a force which is converted into a signal to drive 2 LEDs and programmed to show 3 levels of light emission. This enables the sensors to detect if both fingers are gripping with the correct pressure. With no pressure the LED is off. The 3 display levels are yellow (lightest grip) for chipping and putting, green for all other clubs and red for too tight a grip. The 2 sensors 12 are positioned specifically to pick up the pressure created by the first 3 fingers which form the grip and the position is also strategic in that if the grip is wrong the lights won't work. This is a key advantage in assisting the player to change their grip. The visual feedback is also visible in the peripheral vision as well as direct, if looking in a mirror.

[0030] The sensors 12 are connected to the circuit board in module 16 via an extension of the flexible PCB 14 which joins onto 4 electrical wires which run in the glove lining over to the top of the hand and around to the back of the hand come out and join with the PCB holding the electronics. This PCB is enclosed with a protective silicon housing 16. There is a charge USB port and a charging light to show when charging and when fully charged.

[0031] The electronics and light display 17 are on a flexible lead 14 so it is able to be positioned on the thumb/back of hand region as shown in FIG. 5, using a fastener such as velcro so that depending on the type of swing and grip of the player, the light pressure indicators can be positioned so that the player has a good visual line of sight or peripheral view when swinging. The advantage of this is that feedback is given to the player while swinging, unlike like prior art gloves and applications, where the information is fed to a computer app and then analysed later. The light glove provides instant visual feedback so that the player may adjust the pressure while looking at the lights to see that the correct pressure is being applied.

[0032] A further advantage of this glove embodiment is that information is also given as to whether the grip position, and consequently the club position, is correct. If only one of the LED's is lit it means that there is no pressure on one of the sensors. The embodiment where LED's are individually lit by one of the sensors is best used by a coach in teaching the correct grip. Once that has been taught the unit may be programmed to show the same colour on both LEDs.

[0033] This invention may also be used to sense whether the golfers weight is correctly positioned for a shot and during the shot. The same sensor unit as shown in FIG. 1 or a modified unit having 4 pressure sensors as shown in FIGS. 3 and 4 may be used. The sensor pad 11 is placed under the ball of the foot as in FIG. 3 or under the heel as in FIG. 4. The exact positioning can be adjusted for each user. The electronics module 16 is placed in a visible position on the shoe. FIG. 6 shows it supported on the laces and FIG. 7 shows it held by a Velcro pad on the toe of the shoe. The controller is programmed differently when the device is used in a shoe so that green is shown for correct position and red for incorrect.

[0034] Each of the two lights can show [0035] 1. no colour for no pressure [0036] 2. red for slight pressure [0037] 3. yellow for medium pressure [0038] 4. green maximum foot pressure.

[0039] To use the sensing unit on the glove or in the shoe it needs to be charged and the switched on using a switch on the side of the module 16.

[0040] Usually the glove and shoe units are best utilised so that the glove LED's are showing yellow for a light grip or green for a medium and the ball of the foot sensor is showing green or maximum pressure.

[0041] Using the sensor under the heel will show what weight is being placed on the heel. Depending on the coaching advice the sensors will provide guidance in placing the users weight in the correct position.

[0042] Those skilled in the art will realise that this invention provides a training glove that provides more effective feedback for correcting the golfers grip pressure.

[0043] Those skilled in the art will also realise that this invention may be implemented in embodiments other than those described without departing from the core teaching of this invention.
