The present invention relates generally to a golf aide. In particular, to a golf aide with a tactile indicator for providing tactile feedback during at least a portion of a golf swing.
For centuries golfers have been looking for ways to improve their golf swings. Many golf aides exist and many have a very specific purpose to address or train a specific issue.
For example, there are golf aides which are essentially a regular golf club with modifications made thereto. One example is a golf club which has angled hinges incorporated into the shaft. The purpose of said aide is that if a swing is not proper, the improper forces on the club shaft will cause the hinges in the shaft to move and the user will receive the feedback of the shaft breaking during their swing.
Additionally, there are golf aides which can be added to a golf club such as weights on or near the head of the golf club to help build and train necessary muscle groups.
Still yet, there are golf aides which are completely separate from golf clubs as a whole. For example, there are hoops which are circular and oriented in the plane of a proper golf swing. A user can stand inside the hoop with a golf club and swing along the path of the hoop, thereby training the proper plane of the swing.
However, most of these golf aides have several flaws. For one, any golf aide with a full golf club or needing a full golf club can rarely be used indoors in a home or office environment. Additionally, very few existing golf aides provide tactile feedback to a user where a user can immediately feel, during a swing, if the swing is proper and if it isn't, how the swing can be adjusted.
Many players who receive golf instruction from a pro will receive this type of tactile feedback from the pro during practice. For example, the pro can stop the golfer at the apex of their back swing and physically adjust the positioning of the players hands or body so the player can feel the proper positioning. However, without a pro to give the proper tactile feedback, most players are left to guess if what they are doing is correct or simply rely on imperfect visual feedback, such as by using a video recorder.
The present invention looks to address at least some of the issues present in current golf learning by providing a golf aide which has a tactile indicator capable of providing tactile feedback during a golf swing The small portable size and ease of use makes t possible to use the golf aide anywhere when the golfer has a free moment, in the office, at home etc.
It is an aspect of the invention to provide a golf aide for providing tactile feedback to a user during a golf swing. Example locations during the swing where tactile feedback is to be provided is in the back swing, for example at the apex of the back swing and/or in the slot, or at the follow through, for example at the completion of the swing.
The golf aide has a shaft (12) with a golf grip (11), an arm (14) having a linking element (13) coupling the arm (14) to the shaft (12) at a first end of the arm (14), and a tactile indicator (15) arranged at a distal end of the arm (14) opposite the linking element (13).
The tactile indicator can have a width greater than a width of the arm and/or the shaft. Additionally, the width of the tactile indicatior may be only greater than a portion of the arm and/or shaft.
The shaft (12), arm (14) and tactile indicator (15) can be fixedly arrangeable such that the distance and angle between a portion of the golf grip to be gripped during a golf stroke, for example the middle of the left palm of a right handed golfer, and the tactile indicator is equivalent to a predetermined target distance and angle between hands, for example the middle of the left palm of a right handed golfer, and a lateral upper arm portion of an inside arm of a user at an apex of a backswing of a golf stroke.
The golf aide can also be used to give visual feedback to a user and/or tactile feedback at more than one part of the swing.
The golf aide 10 can have a grip 11 such as a golf grip. The grip 11 can be a standard grip for a golf club. Additional or alternative grips can be used as well on the golf aide. For example, the golf grip 11 can be a metallic, plastic or rubber clinoid or rod for example. The golf grip 11 can contain tactile elements, such as bumps or indentations which can, for example, help a user physically position their hands on the grip. The golf grip 11 can also contain visual element, for example to help a user position their hands on the grip in a desired manner.
The golf aide 10 also can have a shaft 12. The shaft 12 can be a typical golf shaft, for example a steel shaft or carbon shaft of either an iron club or a wood club.
According to certain examples, the grip can function as a shaft in accordance with the present description. Similarly, the shaft can function as a grip in accordance with the present description. The shaft may also be other than a typical golf club shaft, for example being made of a different material than standard and/or having different dimensions. As will be discussed below, the length of the shaft can also be adjustable according to certain examples.
The golf aide 10 can have an arm 14. Furthermore, the golf aide can have a linking element 13 which is capable of, or does couple the arm 14 to the shaft 12. The linking element 13 can be located at a first end of the arm 14. As shown in
The linking element can be such as a hole and pin arrangement, it can be a fixed coupling means such as a screw, glue or the like and/or it can be an adjustable and/or rotatable coupling means, for example such as having an axel for rotating between more than one position of the arm and shaft. In
At the end of the arm 14 opposite to the linking element 13 is located a tactile indicator 15. The tactile indicator 15 can be located at a distal end of the arm 14, where the distal end is that opposite to the linking element.
As can be seen in
Still yet, the end of the arm and the tactile indicator may blend such that the end of the arm and the tactile indicator are generally the same width. In such an example golf aide, the arm 14 can be greater in width than the shaft and/or grip. Additionally, in such an example where the tactile indicator is blended with the arm, the tactile indicator portion of the arm can have a width which is thicker than another portion of the arm.
As shown in the figures, the tactile indicator is a ball, or spherical shape. The tactile indicator can have a number of different shapes including cylindrical, cubic or another organic shape. The tactile indicator is to provide the tactile feedback to the user during a golf swing. The tactile feedback should be pressure and/or friction from the tactile indicator at a desired spot on the user's arm. For examples where the tactile feedback should not be unpleasant, the tactile indicator should not have an overly abrasive surface or shape. The convex curve of a sphere provides an exemplary tactile feedback to a user.
The tactile feedback of from the tactile indicator could also be such that it is pleasant when contacting the user in a correct manner, and somewhat less pleasant when contacting a user in an incorrect manner. For example, a correct manner can be contacting the user's arm in towards the center of the tactile feedback surface in which case that portion can be smooth while away from the center could be rough or contain one or more edges. It is also conceived that the tactile indicator could provide other than pressure/friction feedback, such as a small electric or static shock. Still yet, the tactile indication may contain one or more sensors, such as a pressure sensor and/or inertia sensor.
The shaft 12, arm 14 and tactile indicator 15 can be fixedly arranged in one or more position. For example,
In, for example, an open position, the shaft, arm and tactile indicator can be arranged such that the distance and angle between the grip and the tactile indicator is equivalent to a predetermined target distance and angle. The predetermined target distance and angle can be that which is between a user's hands and a lateral upper arm portion of an inside arm of a user during a particular portion of a golf swing, e.g. during a backswing of a golf stroke, at an apex of a backswing of a golf stroke, or in the slot of the downswing of a golf stroke.
The distance between the two points on the golf aide can be adjusted and/or selected by varying the length of the grip and/or shaft, as well as the angle between the arm and the grip and/or shaft. The distance between the two points can be based on the arm length of the user. For example,
The arm 14 can be curved, as shown in the frontal view of
The arm may also include a bend, for example near the distal end of the arm with the tactile indicator. Such an example is shown in
The arm may also include a twist or a partial twist, for example, starting at or towards the end of the arm connected to the linking element and having the twist extend towards and/or to the tactile indicator, as shown in
The tactile indicator 15 can be capable of rotation. The tactile indicator can be able to rotate, for example, around an axis which is perpendicular to the arm. An example structure will be described with regards to
The linking element, or a portion thereof, can be capable of fixedly arranging the shaft and arm in more than one position. According to certain examples, fixedly arranging includes that in at least one position, e.g. an open position, the shaft and/or grip and arm can be locked with respect to each other. Furthermore, in between two or more positions where the position of the shaft and/or grip and arm are locked, they can be freely located in on or more positions. Each position can allow and/or create a different angle between the shaft and the tactile indicator. Additionally, in one or more position, or in all positions, the rotation of the shaft can be locked.
As discussed above, the golf aide can include a shaft extension mechanism. The shaft extension mechanism may be any mechanical or electromechanical mechanism capable of changing the distance between a point on the shaft and/or grip and a point on the tactile indicator. An example can be seen in
An Example shaft extension mechanism can include a threaded portion on the shaft and a corresponding threaded collar. The threaded collar can then adjust the amount of the shaft which is exposed. The position of the linking element on the shaft can also be adjustable to change the effective length of the shaft, e.g. the distance between an end of the grip and the linking element.
In an example such as shown in
The shaft 12 can include a hollow center where a see-saw pin 24 can be inserted. The see-saw pin can have a crossed shape with a flat head and pin extending perpendicularly therefrom. The bottom of the pin, opposite the head, can be angled. The bottom of the pin 24 can also be flat or other shaped. There may also be a pin extension 27 having, for example, an angled end which is inserted into the hollow opening of the shaft and in contact with the see-saw pin 24. The shaft 12 can have an opening 23 from which a tab 26 can optionally protrude. The tab 26 can have an angled portion which corresponds to the angle of either the see-saw pin bottom or the pin extension. Furthermore, the shaft assembly can include a spring located under one or both ends of the flat head of the see-saw pin 24. The function of any or all of these pieces can be combined into fewer discrete parts. In operation, the shaft assembly would be inserted within the female locking insert, or optionally just within a grip or grip housing.
The arm 14 can have a first end 14a with a geometry as shown in
The geometry of the first end 14a can also be such that in an open position, there is pressure on the top of the see-saw pin and the same locking action occurs. However, the geometry of the first end 14a can be such that in a partially open position, there is no or little pressure on the top of the see-saw pin. As such, the spring located under the head extensions of the pin can push the see-saw pin up, releasing pressure on the tab such that it can retract through at least a portion of the opening 22 of the female locking insert 22 so as to allow extension of the shaft/shaft assembly or retraction of the shaft with respect to the grip/grip assembly.
The same principle can be applied through different means. For example, there can be one or more discrete locking or locked positions where different internal mechanisms are used to lock shaft and grip with each other. Similarly, the operation of the mechanism described can be reversed so that pressure on a pin within the shaft can un-lock the shaft/shaft assembly and grip/grip assembly. Numerous variations can be conceived by those of ordinary skill in the art which do not depart from the scope of the present invention.
The distal end 14b of the arm 14 can have a geometry or opening which is capable of receiving one or more portions of the tactile indicator 15. In the example of
The shaft and the grip can be arranged linearly in a first plane. The arm can have a thickness in the plane of the shaft and grip. The arm can have a first indicator on one side of the thickness and a second indicator, different from the first, on the opposite side of the thickness. Such indicators can be a tactile indicators as shown in
Additionally, there can be one or more visual indicators on one or more sides of the arm. As an example, one side of the arm can have a first color and the other side can have another, contrasting color. When the golf aide is swung, the user can then see at the perceived point of contact with a ball one of the two colors.
Through this visual feedback they can tell if the golf aide is properly rotated at impact or improperly rotated.
The predetermined target distance and angle between the hands and lateral upper arm portion of a user can be selectable before use of the golf aide. The linking element and/or a shaft extension mechanism can be capable of fixedly arranging the same distance and angle between the grip, arm and tactile indicator. Example use of the golf aid is discussed below.
The golf aide 10, in the open position for use as shown, has the arm 14 extending away from the grip 11 and shaft 12 with the tactile indicator 15 located at the distal end of the arm 14 opposite the end of the arm 14 coupled to the shaft 12. The distance 53 and angle between the portion of the grip 11 to be held by the hands 52 of the user 50 and the tactile indicator 15 is equivalent to the distance and angle between the hands of the user 52 and the lateral portion of the upper arm 51 of the inside arm of the user during a backswing of a golf stroke. For example, in the picture the user is right handed and the inside arm of the backswing is the right arm.
During use of the golf aide, the user will hold the grip of the golf aide as a normal club in an address position, e.g. as if to hit an imaginary golf ball. The grip, arm and tactile indicator should all be in line with each other extending from the hands towards the ground. The user should then proceed with the back swing as normal, both rotating their wrists and breaking their inside elbow of the swing. At the climax of the target backswing, the tactile indicator will make contact with the lateral portion of the upper arm 51 of the user 50.
By lateral portion of the upper arm, it is meant the side of the upper arm when considering a person standing straight, as opposed to the front of the arm. Stated another way, for a one plane swing, the lateral portion of the upper arm 51 of the user is near or nearer to the intersection of the deltoid, triceps brachii and biceps brachii as opposed to near the center of either the biceps brachii or triceps brachii.
The lateral portion of the upper arm of a two plane swing would be more completely on the deltoid.
During a desired, target golf back swing, the tactile indicator will make light to moderate contact with the lateral portion of the upper arm. A common error in user's backswings is an over swing, where the hands travel further than intended up and behind the user's head. The contact between the tactile indicator and the users upper arm provides immediate tactile feedback as to the proper length of the backswing and limits or prevents over backswing, i.e. once the tactile indicator contacts the user's body, regardless of where the tactile indicator contacts the body the user is instantly alerted that the backswing should no longer be continued.
A second common error in a user's backswing is that at the climax of the backswing, the user's wrists and elbows are not in the proper/optimal position. During a typical swing, a golf instructor can easily look at the position and orientation of the head of a golf club in a backswing and provide feedback to the user if the wrists and elbows are in the proper position based on their view of the club head. However, it is impossible for the user to see the head position and orientation during the back swing as the club head should be positioned behind and above the user's head.
Due to the distance and angle between the golf grip, e.g. the portion of the golf grip or the center of the portion of the golf grip held in the hands of the user, and the tactile indicator, at the correct climax of the backswing the tactile indicator will touch the correct portion of the lateral portion of the upper arm of the user, e.g. near or at the intersection of the deltoid, triceps brachii and/or biceps brachii of the user for a one plane swing. Essentially, the golf aide takes the visual cues of the head of a normal golf club during a backswing and coverts those visual cues to tactile cues with the tactile indicator.
As such, if the wrists are over rotated in an “open club face position”, for example, the tactile indicator may fall towards the back of the upper arm, e.g. more on the triceps brachii than intended during the target backswing. If the wrists are under rotated in a “closed club face position”, for example, the tactile indicator may fall towards the front of the upper arm, more on the biceps brachii than intended during the target backswing. Similarly, if the angle between user's forearm and upper arm is incorrect, the tactile indicator may fall higher or lower on the upper arm than intended, e.g. higher or lower than intended on the lateral portion of the upper arm, e.g. towards the center of the upper arm opposed to towards the intersection of the deltoid, triceps brachii and biceps brachii or more towards the center of the deltoid.
For each user, the optimal position of the tactile indicator at the climax of the golf swing can be determined and indicated for the user. Then, in every swing it is possible for the user to determine how if they have achieved the target backswing or if they have missed the target location of the climax of the backswing. Additionally, the tactile indicator can be used by the user to move the position of the wrists and arms/elbows after a practice backswing which is improper to bring the position and orientation of the user's backswing to the correct position and orientation by feel, something that would not be possible with a regular golf club as the user would need to twist their head to see the face of the golf club which would necessarily change the position and orientation of the original backswing.
A third common error in a user's swing is that once they leave the climax of the backswing to impact the ball, the user “pushes” their hands away from their body on the downswing causing the club face to open prior to contacting the ball and resulting in an slice. The “push” of the hands often occurs at the top of the downswing, before the slot as shown in
As shown in
In order to facilitate the movement of the tactile indicator down the upper arm of the user, the tactile indicator may be rotatable. The tactile indicator may be spherical and capable of rotation about more than one axis. The tactile indicator may also be spherical, cylindrical or of other shape and only rotateable around a single axis. The single axis can be perpendicular to the arm of the golf aide such that the tactile indicator will only travel smoothly in a motion straight down the user's arm during a target golf swing. If the movement of the tactile indicator is not perpendicular to the axis of rotation of the tactile indicator then the user should experience friction, indicating that additional and undesired rotation is occurring during the user's downswing.
The golf aide can be used to give other, similar feedback during the swing. For example, the tactile indicator can be positioned at a desired location at the end of the follow through so that a user can receive tactile feedback at the end of the swing, for example on the back of the head or nape of the neck. The golf aide may have additional markings which provide information to the user and/or provide additional means of feedback for the user. For example, if the arm of the golf aide has a noticeable thickness, for example in the plane of the grip and shaft as shown in the figures, in particular in
