BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a golf shot alignment device and system.

In particular, one embodiment of the present invention is directed towards a club-mounted aiming indicator which co-operates with a viewfinder and/or a software-based application to form a system which can be used to indicate to a golfer when the club the golfer is holding is aligned correctly towards a chosen target. Moreover, another embodiment of the present invention is directed towards a golf club mounted golf shot alignment device which can be used to indicate to a golfer when the club the golfer is holding is aligned correctly towards a chosen target.

Throughout this specification, the term “viewfinder” shall be understood to encompass any type of device which may be used by a golfer to select a target in the distance which they will aim their golf shot towards.

Golf is a widely played game throughout the World. A game of golf is won by completing all of the holes on the course in the fewest number of golf shots. Thus, it is imperative that a golfer aligns their golf club correctly towards their chosen target. A large majority of golfers are able to correctly select the target area where their next golf shot should be played, however up to 95% of golfers then introduce an alignment error when setting up their golf shot. This causes many golf shots to veer away from the intended target and results in golfers handing in higher score cards.

In addressing a golf ball, to strike the golf ball towards the intended target, the golfer should align the club face substantially orthogonally to an imaginary aiming line which is directed from the golf ball towards the intended target. If the golf club is aligned and swung correctly, the likelihood of this striking the golf ball towards the intended target substantially increases.

Most individuals have stronger vision in one eye over the other. And when a golfer transitions from facing the target area straight on, to facing the target sideways on, thus adopting the position to swing their golf club, alignment errors are introduced. This is exacerbated by the golfer having stronger vision in one eye over the other, and this is further worsened when the golfer stands side on, addressing the golf ball to be struck, with either the weaker eye or stronger eye in front of the other and thus biasing their vision and perception of where to aim to strike towards the target.

It is a goal of the present invention to provide an apparatus that overcomes at least one of the above-mentioned problems by assisting a golfer in aligning their golf club correctly when addressing their golf ball, so as to strike the golf ball towards an intended target.

The present invention is intended to be used on golf courses, during practice rounds; however, it will be appreciated that use of the present invention in swing bays, on driving ranges, and the like is also envisaged.

SUMMARY

The present invention is generally concerned with assisting a golfer to align a golf club face towards a selected target by offering the golfer a target selection device which can capture a direction towards the target and an indicator device which can inform the golfer when their golf club face is aligned towards the selected target.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Referring toFIG.1, there is provided golf shot alignment system, in accordance with one embodiment of the present invention, indicated generally by reference numeral100. The golf shot alignment system100assists a golfer indicated generally by reference numeral116to align a golf club face124towards a selected target110. The golf shot alignment system100comprises a target selection device indicated generally by reference numerals102,104which is remote from a golf club mounted indicator device106. The golf club mounted indicator device106is mounted on a golf club120which comprises the golf club face124.

The target selection device102,104can communicate wirelessly with the golf club mounted indicator device106so as to provide target information from the target selection device102,104to the golf club mounted indicator device106.

The golf club mounted indicator device106uses the target information which it receives to determine when the golf club face124is aligned towards the selected target110and then indicates this to the golfer116.

In the preferred embodiment of the invention, the target selection device102,104comprises a handheld unit indicated generally by reference numeral102and a viewfinder indicated generally by reference numeral104. However, it will be appreciated that the present invention may operate by having the handheld unit102acting solely as the target selection device, or, by having the viewfinder104acting solely as the target selection device. The advantage, it has been found, by forcing a golfer116to select the target through the viewfinder104is that the golfer116becomes accustomed to selecting a target when standing facing on to the target area, and then associating the correct club alignment to the selected target, when the golfer116is standing side on whilst addressing the golf ball to be struck.

The handheld unit102comprises a location means (not shown) to provide a current location. This will typically be provided by way of a GPS component device incorporated into the handheld unit102. The handheld unit102comprises a screen108to display at least a portion of a surrounding area. The surrounding area, it will be appreciated, will typically be a satellite map or a diagrammatic view of at least a portion of the golf hole currently being played by the golfer116. The handheld unit102preferably comprises a touchscreen so as to allow the golfer116to adjust an on-screen aiming line111. The aiming line111emanates from the provided current location112and extends to the selected on-screen target110. It will be appreciated that the aiming line111will be overlaid on the displayed surrounding area on the screen108. The golfer116can simply move the aiming line111around on the screen108to select a target point110on the map which they wish to aim their next golf shot towards.

In a preferred embodiment, the handheld unit102may provide distance to target information, and/or club selection information (based on historical records for the golfer's average distances per club, or based on information input by the golfer). The handheld unit102will also comprise a means for determining the target information, or alternatively referred to as aiming information, based on the selected on-screen target. The target information/aiming information may be a direction vector, or target co-ordinates, or the like. If the handheld unit106is acting on its own, then the handheld unit106will comprise a wireless transmitter (not shown) for wirelessly transmitting114,118the target information to the golf club mounted indicator device106. Alternatively, if the viewfinder104is being used in conjunction with the handheld unit102, then the handheld unit102will comprise a wireless transmitter or a wired connection (not shown) for wirelessly transmitting114or sending the aiming information to the viewfinder104.

Turning briefly toFIG.2, the handheld unit102is shown mounted in a bracket202comprising a physically connected viewfinder104. A satellite map200is displayed on the screen108. The handheld unit102is a smartphone in this embodiment.

Returning toFIG.1, the viewfinder104comprises an orientation means (not shown) for assessing which orientation the viewfinder104currently has. This orientation means may simply be a compass, or magnetometer, which can provide information on the directional orientation of the viewfinder104. When the golfer116presses a capture button117there will be means, such as a memory, for capturing the orientation from the orientation means. The golfer116may be prompted to press the capture button117when the viewfinder104is aiming at the selected on-screen target110. The aiming information can be cross-checked continually against the orientation provided by the orientation means and can indicate to the golfer116when the current orientation of the viewfinder104is in agreement with the provided aiming information from the handheld unit102. This prompt may be a light, or sound, or tactile vibration. One preferred example is to turn a cross-hair on the viewfinder104to a different colour, say green, when the current orientation of the viewfinder104is in agreement with the provided aiming information from the handheld unit102. When the golfer116presses the capture button on the viewfinder104, the target information, which will be based on the current orientation of the viewfinder104and/or on the aiming information, will be wirelessly transmitted to the golf club mounted indicator device106by a transmitter (not shown) in the viewfinder104.

In an alternative embodiment, where the viewfinder104is acting without the handheld unit102, the golfer116will be prompted to press the capture button117when the golfer116views their selected target through the viewfinder104. Again, when the golfer116presses the capture button117on the viewfinder104, the target information, which will be based on the current orientation of the viewfinder104will be wirelessly transmitted to the golf club mounted indicator device106by a transmitter (not shown) in the viewfinder104.

The golf club mounted indicator device106is mounted on a golf club120, or may be integrally formed as part of a golf club120during manufacture. The golf club mounted indicator device106comprises means for receiving target information from the target selection device102,104. This will normally be in the form of a direction which the golf club face124should be aligned along, or information which could be used to derive a direction which the golf club face124should aligned along.

The golf club mounted indicator device106will also comprise means (not shown) for determining a positioning of the golf club face124. This means for determining a positioning of the golf club face124may comprise one or more of an accelerometer, a gyroscope, a magnetometer, and/or a compass. This provides information on the current positioning of the golf club face124.

There may also be provided a processor within the golf club mounted indicator device106to use the target information received by the golf club mounted indicator device106and the information from the accelerometer, the gyroscope, the magnetometer and/or the compass, so as to determine when the golf club face124is aligned towards the selected target.

In alternative embodiments, the processor may be provided in the viewfinder104or the handheld unit102and in this embodiment, the golf club mounted indicator device106would comprise a transceiver to send information from the accelerometer, the gyroscope, the magnetometer and/or the compass, and, to receive indicator on or indicator off information from the processor which will be located remotely from the golf club mounted indicator device106. In this manner, power intensive computation and processing can be done remotely form the golf club mounted indicator device106.

Referring now toFIG.3, the golf club mounted indicator device106is mounted on a top end portion indicated generally by reference numeral300of a golf club handgrip122at a top end of a golf club120shaft. The top end portion300is at an opposite end of the golf club120to the golf club face124. A light emitting diode (LED)302is provided as the indicator light on the golf club mounted indicator device106. The light emitting diode (LED)302will turn from green to red when the golf club face124is aligned to the selected target.

In further embodiments, other types of indicators may be used to indicate when the positioning of the golf club face124is suitable to align the golf club face124towards the selected target110. For example, the golf club mounted indicator device106may comprise a light, as above, although not necessarily a LED light, to provide feedback on the alignment of the golf club face124, or, the golf club mounted indicator device106may comprises a haptic engine to provide vibrational feedback on the alignment of the golf club face124or a speaker to provide a sound when the golf club face124is aligned correctly.

In a preferred embodiment of the invention, and in order to save the power being consumed by the golf club mounted indicator device106, the golf club mounted indicator device106comprises a tip switch which is used to control the power being fed to the golf club mounted indicator device106. When the golf club120is placed in a golf bag, the golf club120will have its golf club face124above the golf club handgrip122. In essence, the golf club120will be upside down and so too will the golf club mounted indicator device106be upside down. When the tip switch senses that the golf club mounted indicator device106is upside down, the power will be prevented from being supplied to the golf club mounted indicator device106and the golf club mounted indicator device106will be effectively powered off. When the tip switch senses that the golfer116has taken the golf club120out of the golf bag and the golf club120has been rotated by a preset angle, say 135° from its upside-down situation, the tip switch will power back on the golf club mounted indicator device106.

In a further embodiment, the viewfinder104may further comprise a rangefinder to allow a golfer116to determine a distance to a pin or their intended target110. The range finder may preferably be of a standard laser range finder design.

Turning now toFIGS.4ato4cinclusive, there is shown another embodiment of the present invention. A golf club mounted golf shot alignment device is indicated generally by reference numeral400. The golf club mounted golf shot alignment device400is used to assist a golfer116to align a golf club face124towards a selected target402. The golf club mounted golf shot alignment device400comprises a target selection device and an indicator device. The golf shot alignment device400is mounted on a golf club120which comprises the golf club face124. In a preferred embodiment the golf shot alignment device400is mounted on a top end of a handgrip122of the golf club120.

In use, a golfer will hold their golf club120is a substantially horizontal position and point the golf club120towards an intended target402. That is, the golf club120is aligned between their golf ball125at the current location112and the intended target402which might be the centre of a fairway or a flagstick on a green for example. This is shown inFIG.4a. When the golfer116is satisfied that the longitudinal axis of the shaft of the golf club120is correctly aimed at the intended target402, the golfer116will push a button302on the golf club mounted golf shot alignment device400as shown inFIG.4b. This triggers the target selection device to capture the direction in which the golf club120is being pointed. This target information captured by the target selection device is then passed to the indicator device in the golf club mounted golf shot alignment device400. The target selection device is therefore capable of communicating with the indicator device so as to provide target information from the target selection device to the indicator device. The golfer116will then, having pressed a button302or completed some analogous action which has triggered the target selection device to capture the target information and caused the target information to be passed on to the indicator device, return the golf club120to the normal substantially vertical playing position (as shown inFIG.4c) and begin to line up their shot towards the intended target402. The indicator device comprises means to use the target information to determine when the golf club face124is aligned towards the selected target402. An indicator302incorporated in the button302is then activated on the golf club mounted golf shot alignment device400to indicate to the golfer116that the golf club face124is now aimed towards the target402. This is shown inFIG.4c.

It will be appreciated that, as before, a light emitting diode (LED)302is provided as the indicator light on the golf club mounted golf shot alignment device400shown inFIGS.4ato4c. Although, in further embodiments, other types of indicators may be used to indicate when the positioning of the golf club face124is suitable to align the golf club face124towards the selected target402, such as, any type of light, a haptic engine, or, a speaker to indicate to the golfer116when the golf club face124is aligned correctly to the target402.

As with the preceding embodiments, where the target selection device and the indicator device were remote from one another, the advantage with forcing the golfer116to line up their next shot using their golf club120in a substantially horizontal manner is that the golfer116becomes accustomed to selecting the target402when standing predominately facing on to the target402, and then further accustomed to associating the correct club alignment to the selected target402, when the golfer116is standing side on to the target402, as is normal when addressing the golf ball125to be struck.

This embodiment, where the target device and indicator device are incorporated into a single golf club mounted device400will work analogously to the earlier described embodiment. In this current embodiment, the target device will comprise an orientation means (not shown) for assessing which orientation the golf club120currently has. This orientation means may simply be a compass, or magnetometer, which can provide information on the directional orientation of the golf club120.

When the golfer116presses the capture button302there will be means, such as a memory, for capturing the target information from the orientation means. The target information will typically be in the form of a direction which the golf club face124should be aligned towards. Alternatively, the target information may comprise information which could be used to derive a direction which the golf club face124should be aligned towards.

The golf club mounted golf shot alignment device400will also comprise means (not shown) for determining a positioning of the golf club face124. This means for determining a positioning of the golf club face124may comprise one or more of an accelerometer, a gyroscope, a magnetometer, and/or a compass. This provides information on the current positioning of the golf club face124. There may also be provided a processor within golf club mounted golf shot alignment device400to use the target information and the information from the accelerometer, the gyroscope, the magnetometer and/or the compass, so as to determine when golf club face124is aligned towards the selected target402.

With reference toFIGS.5aand5b, there is shown another embodiment of the present invention. A golf club mounted golf shot alignment device is indicated generally by reference numeral500. The golf club mounted golf shot alignment device500is again used to assist a golfer to align a golf club face124towards a selected target110,402. As with the embodiment shown inFIGS.4ato4c, the golf club mounted golf shot alignment device500comprises a target selection device and an indicator device. As seen inFIG.5b, the golf shot alignment device500is mounted on a golf club120which comprises the golf club face124. In a preferred embodiment the golf shot alignment device500is mounted on a top end of a handgrip122of the golf club120.

The golf shot alignment device500comprises a button504to trigger the target selection device to capture the direction in which the golf club120is being pointed. This target information captured by the target selection device is then passed to the indicator device in the golf club mounted golf shot alignment device500. When the golfer returns the golf club120to the normal substantially vertical playing position and begins to line up their shot towards the intended target110,402, the indicator device comprises means to use the target information to determine when the golf club face124is aligned towards the selected target110,402. An indicator502is then activated on the golf club mounted golf shot alignment device500to indicate to the golfer116that the golf club face124is now aimed towards the target110,402or is off target.

The indicator502may comprise a plurality of circumferentially spaced-apart LEDs as shown inFIG.5a. The indicator502may be illuminated in one colour, say blue, if the club face124is closed, or another colour, say orange, if the club face124is open, or a third colour, say green, if the club face124is square on to the selected target110,402. The indication that the club face124is open or closed will help the golfer116line up their shot in a shorter amount of time.

As before, in further embodiments, other types of indicators may be used to indicate when the positioning of the golf club face124is suitable to align the golf club face124towards the selected target110,402, such as, any type of light, a haptic engine, or, a speaker to indicate to the golfer when the golf club face124is aligned correctly to the target110,402.

The golf shot alignment device500further comprises a rotating click-wheel506, or an analogous input means, which enables a golfer116to request the golf shot alignment device500to align the club face124intentionally off target from the selected target110,402. This is useful if the golfer wishes to shape an approach shot or a drive, around an obstacle on the course. For example, each click rotation of the wheel506may represent a 1°, 2°, 5° or other preset amount off the target110,402. It will be understood that rotating in a clockwise manner (when viewing the golf shot alignment device500from the top, free end of the golf shot alignment device500), may open up the club face124to assist with a fade shot, or, rotating in an anti-clockwise manner (when viewing the golf shot alignment device500from the top, free end of the golf shot alignment device500), may close the club face124to assist with a draw shot.

It will be appreciated that the viewfinder104or the handheld unit102of the earlier described embodiments could also be used to input an intentional offset to a selected target110,402. The offset input may be also used for countering a golfer's natural swing errors, although it will be appreciated that this type of use is not helpful for improving and correcting such errors.

In a further embodiment, the golf club mounted indicator device106of the golf shot alignment system100, or the golf club mounted golf shot alignment device400,500may comprise means to recognise when the golf club120has struck a golf ball125. An accelerometer or such device may be used to detect such an impact. At the time of the detected impact, the golf club mounted indicator device or the golf club mounted golf shot alignment device400,500would detect, using the same components as used for lining up a shot, whether the golf club face124was open, closed or square on to the selected target at impact. Where an intentional offset has been input to the golf club mounted golf shot alignment device500, this would be taken into account when detecting if the golf club face124had the correct alignment at the time of impact.

Over time, as a historical record of a golfer's tendencies is established, in yet a further embodiment, the golf club mounted indicator device106, or the golf club mounted golf shot alignment device400,500may automatically correct for the tendencies of a specific golfer by automatically offsetting the club face angle from the selected target110,402in order to correct for the golfer's natural habit to open or close the club face124. The degree to which this offset is countered automatically can be established by averaging out the historical records. Where a golf shot is struck by the golfer116, and the golf club face124is significantly open or closed, say by 30° or more, then the averaging process may ignore such records as it is clearly a badly mishit shot. Again, this feature of this embodiment is not good for helping a golfer116to improve their game as it attempts to counter a golfer's natural bad habits; however, it may be useful in certain situations where a golfer116wishes to have more immediate assistance in hitting more accurate golf shots.

For charging of the golf club mounted devices, in a further embodiment of the present invention, it is also envisaged to use wireless charging means as are known in the art, such as using an electromagnetic field by way of inductive charging. Typically, a primary coil in a charging pad or mat is used to create an electromagnetic field which through inductive coupling is linked to a secondary coil and charges a device106,400,500incorporating the secondary coil. Other techniques are also known and included within the scope of this application. It is envisaged to place the charging pad/mat on top of an interior floor of a golf bag, or possibly integrate the primary coil into the floor of the golf bag during manufacture. In this way, when a golf club120is returned to the golf bag in the normal manner, the golf club mounted device106,400,500will sit directly on top of, or in very close proximity to, such a charging pad/mat. A small rechargeable battery in the golf club mounted device106,400,500could then be recharged via such wireless charging means.
