Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention comprises a club head and a connecting means that connects the club head to a shaft and includes adjustment means for adjusting the relative position therebetween, The present invention relates to golf aids that can make it possible to provide custom-made golf clubs.

[Conventional technology]

Various golf clubs are used depending on the height, weight, arm length, physical strength, etc. of the player. Furthermore, although golf clubs of different lengths, weights, etc. are prepared for this purpose, there are not many types of golf clubs that are suitable for individual players who have slightly different conditions.

Golf clubs such as Naori love heads whose weight can be adjusted have already been proposed.

[Problem that the invention seeks to solve]

However, such a device that only adjusts the weight of the club head is not optimal for each individual, and it is difficult to find a truly user-friendly golf club.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a golf aid that allows adjustment of the club head and shaft and facilitates the manufacture of custom club heads.

[Means for solving problems]

The golf aid of the present invention includes a club head and a coupling means for coupling a shaft to the club head, and the coupling means includes adjustment means.

The coupling means includes at least one rotatable adjustment means for adjusting the angle of the striking surface of the club head relative to the shaft. The coupling means also includes at least one rotatable adjustment means for allowing adjustment of the angle of the shaft relative to the club head.

In a preferred embodiment, the connecting means includes a pair of rotatable adjusting means for adjusting the angle of the shaft relative to the club head about two different axes in the same plane.

The first rotatable adjustment means serves to adjust the distance of the club head from the brake. A second adjustment means in the same plane is capable of adjusting the balance of the club head and maintains the club head perpendicular to the trajectory of the golf pole while the club head approaches the golf ball during the stroke. Compensate.

The coupling means may further include adjustable attachment means for adjusting the attachment position of the shaft longitudinally of the club head. The attachment means may also be formed in a series of bows formed on the club head to which each of the coupling means may be secured. In a cultural embodiment, the attachment means may employ a slot with clamping means for repositionably securing the shaft. The slot may be dovetail shaped and the securing means may include a dovetail member movably engaging the slot.

Positioning means may be provided for removably attaching a plurality of different weights to the club head so as to adjust the weight of the club head. It should be noted that the positioning means receives a weight, for example a dovetail groove.

The shaft may also be attached to the coupling means and may include axial adjustment means for adjusting its effective length.

In another embodiment, the coupling means comprises a handle defining an internal bore and a longitudinally extending slot. The shaft can therefore be used to compress the longitudinal slot and secure the handle to the shaft by a zero-conical locking nut which can be inserted into the bore to varying degrees. The attachment of the shaft to the club head may be similarly adjusted.

In another embodiment, the handle may be provided with an internal thread, and the shaft may be provided with a relatively long external thread, and the shaft may be fixed to the handle at any position using a lock nut.

Instructing means can be used to specify a specific position of the club head relative to the shirt 1-, a specific length of the shaft, etc., so that after trying out various positions, lengths, etc., Breyer can record the recorded data. Create a custom-made preferred club based on your preferences.

Additionally, the club head can be formed using different materials with varying modulus of elasticity, such as using a material with better elasticity for the striking surface than other parts of the head.

The golf aid of the present invention may also be used in the manufacture of golf clubs by adjusting the club head relative to the shaft and then securing the adjustment means to prevent further adjustment.

In a cultural embodiment, the golf aid itself may be used as a golf club by enclosing the adjustment portion to prohibit further adjustment.

In still other embodiments, the adjustment values may be recorded and used to later manufacture golf clubs.

Hereinafter, one embodiment of the means of the present invention will be described based on the drawings.

In FIG. 1, numeral 10 indicates a golf aid that provides golf clubs that are custom made to specific players.The golf aid 10 includes a club head 12, a shaft 14,
and a handle 16.

A rotatable coupling means 18, generally indicated at 18, is used to couple the shaft 14 to the club head 12. The effective lengths of the shaft 14 and the handle 16 can be changed by adjusting a shaft adjuster 20, which in this example is a conical lock nut.

The method of fixing the handle 16 to the shaft 12 is shown in more detail in FIG. 2.The handle 16 has an inner hole into which an axially extending sleeve 22 is fitted, and a covering around the outer periphery of the sleeve 22 is provided with a sleeve 22 that extends in the axial direction. You can change it according to your preference. The handle 16 also has an end cap 24 at one end and a plurality of axially extending slots 26 at the other end. After the shaft 16 has been inserted to the desired length into the inner bore of the handle 16, the slot 26 can be tightened and secured by simply tightening the lock nut.

The shaft 14 is provided with a number of axially spaced scales, not shown, which are used as markers to record when a particularly effective length for a given brayer has been determined.

In addition, instead of the above-mentioned structure, by fitting the shaft 14 with a spigot and using a fixing device such as a set screw or a lock nut,
A spigot or stopper that can be repositionably secured to shaft 14 is also used. The handle 16 is adjustably attached to the other end of the stopper. Alternatively, the length can be adjusted by providing a long external thread on the shaft 14 and an internal thread on the handle 16. At that time, the shaft adjusting means 20 such as a lock nut is used to fix the shaft. Also, if necessary,
The handle 16 can also be replaceably fixed to the stopper or the shirt I.14 via a corrector that is made of elastic Pi material.

The connecting means 18 is shown in FIG. 3 in an enlarged manner.
&18 includes an upper member 28 rotatably attached to a lower member 30, and the upper and lower members 28, 30 are in turn rotatably connected to the rad 12 to the club. Therefore, shaft 1
4 relative to the club head 12 can be adjusted.

If a suitable position is found, the relative position of the upper member 28 with respect to the lower member 30 can be indicated and recorded by the needle-like indicating means 32. Similarly, the indicating means 34 may also record the relative position of the club head 12 with respect to the lower member 30.

For adjustment, the adjusting means 36, 38 of the coupling means 18, in this example a nut, are tightened and loosened. Adjustment means 36.3
8 inserts the final golf club into the upper member 2 by sinking it into a recess (not shown) together with the indicating means 32 and 34.

4 and 5 show a case in which the relative position of the lower member 30 to the club radius 12 can be adjusted in the length direction of the head 12 by extending a slot 42 in the club head 12. The fixed pin 43 also includes a slope 44 that matches the striking surface of the club head 12. The striking surface of the club head 12 can be angled in the opposite direction from the vertical as shown in FIG. 5, or it can be formed exactly vertical. In addition, the lower corner part of the hitting surface is designed to reduce frictional resistance with the grass when hitting the golf ball.
As shown in FIG. 5, it is preferably formed into a circular arc. In the front view, the head of the fixed bottle 43 has a rectangular shape and is provided with an indicator line 46.

Accordingly, it is preferable that the club head 12 also be provided with appropriate scales to facilitate recording of the appropriate selected position.

Furthermore, a plurality of holes may be used instead of the slot 42, and the fixing pin 43 can be attached to the hole. Such adjustments are particularly preferred when the golf club is a putter.

As an alternative to the structure shown in FIG. 5, the slot 42 could be located on the back of the club head 12 rather than on the striking surface. The fixing pin 43 may be made shorter and directly fastened to an appropriate position on the club head 12. Furthermore, the slot 42 may be provided on the back surface of the club head 12, and the slot 42 may be formed in a shape such as a dovetail or T-shape, with the back part wider than the entrance part. , whose head has the same shape as the slot and projects outward from the back surface of the club head 12. Further, the head of the fixed bottle 43 may extend in the longitudinal direction of the slot 42, and the head of the fixed bottle 42 is provided with a set screw, which when tightened presses the bottom of the slot.
The head of the locking pin 42 can be biased outwardly to firmly retain the pin 43 within the slot 42.

The lower member 30 is held by a fixed bin 43, and the indicating means 34 fixed to the outer end of the fixed bin 43 is
It rotates as the club head 12 rotates.

Additionally, additional weight may be inserted into the throttle 2 to increase the weight of the club head.

The lower member 30 is slid into an appropriate position in the groove 40 using one or more setscrews, and is adjusted by tightening the setscrews while causing the lower member 30 to be oriented outward relative to 440. Fixed as possible.

Lower member 30 and upper member 28 may be replaced by a lockable universal joint.

The upper member 28 of the coupling means 18 may include a socket (not shown) for receiving the end of the shaft 14. By screwing the lower end of the shaft 14 into the threaded socket, the socket serves to further adjust the effective length of the shaft 14.

The lower end of the upper member 28 is flattened, and this flat portion is supported between a pair of protrusions of the lower member 30, as shown in FIG.

As shown in FIGS. 6 to 8, a connecting member 52 can be attached to the upper member 28 and lower member 30 forming the connecting means 18. Connecting member 52 provides additional in-plane adjustment. That is, the adjustment means 54 for the club head 12
and its relative position to the shaft (not shown) can be adjusted by adjusting means 56. in this way,
The club head 12 can rotate around two different axes within the same plane.

The adjustment means 54, which is a locking screw, includes a slide piece 58 which engages a slot 60 of the same shape in the rad 12 to the club while the adjustment hand is closed. t56 is
The lower member 30 can be fixed to the connecting member 52. Also, adjustment means 5
4 also makes it possible to adjust the relative longitudinal position of the club head; thus, the adjusting means 54, the slot 60 and the dovetail slide piece 58 longitudinally adjust the position of the shaft 14. It constitutes a means for attaching the shaft.

Furthermore, the adjustment means 62, which is a screw, is adapted to the adjustment means 54.
The angle of inclination of the shirt 1-14 relative to the club head 12 can be adjusted at an axis perpendicular to the axis 56.

The main difference between the embodiment of FIG. 8 and the embodiments of FIGS. 6-7 is that in the former, as shown in FIG. On the other hand, in the latter case, the connecting member 52 is eccentric with respect to the lower member 30, as shown in FIG.

In these embodiments, the connecting member 52 is fixed in a generally vertical position to assist the golfer in correctly hitting the golf ball when addressing the golf ball.

Adjustment means 56, which is a locking screw, is used to adjust the distance of club head 12 from the player. By adjusting the position and angle of the adjusting means 54, the club head 1
The balance between the two is affected.

Thus, the further the adjusting means 54 moves along the slot 60 away from the player, the more the club head 12 will tend to rotate inwardly upon impact. The adjusting means 54 is configured to adjust the length of the club head 1 by adjusting the adjusting means 54 in the lengthwise direction of the club head 12.
The angle of the shaft 14 relative to the club head 12 can be adjusted to compensate for the imbalance.

The golf aid shown in FIGS. 6-8 includes adjustment means 54.56.
．． 62 is preferably recessed and installed to seal it, for example by welding, overlaying, soldering, etc.

To prevent containment weight from affecting the weight of the club, weight is removed from, for example, the dovetail slide 58 to compensate.

Said slot 60 and other slots 64 provide a convenient location for attaching labels or other writing materials, and may also be used by golfers.
When addressing the golf ball, it is possible to hide it from the line of sight and prevent confusion when hitting it.

Club head 12 preferably includes bulbous portions 66 at each end that provide additional weight to the club head.

As shown in FIG. 7, a slot 68 can be provided and the depth of the slot 68 can vary along the length of the club head 12. This gives the IT distribution of the club head such that when the golfer addresses the golf ball and, in the correct stance, the golf club contacts the ground, the club is automatically oriented perpendicular to the ball's trajectory. The depth of the slots 64, 60, which serve the same purpose, and the bulbous portion 66, which can be varied for the same purpose, are adjusted, such as by machining, to provide a preferred weight distribution.

Although the golf club of FIG. 9 includes a connecting arm 8t18 that is adjustable in only one direction, it can also be formed to be similar to the previous embodiment.

In this embodiment, the lower member 30 passes through the head 12 and is provided with a base 70 at its lower end.

The lower member 30 and the base 70 can be molded from a wear-resistant material, such as stainless steel, while the head 1
The other parts of 2 are filled with 90.7% copper, 4.4% nickel, 4.3% iron, and are filled with an elastic material such as phosphor bronze.
It can also be formed using a material containing 0.32% zinc, 0.1% tin, and 0.06% phosphorus (each % by weight). Head 1 like this
2 can be formed using materials having different elastic moduli. Further, if desired, a mounting portion for firmly fixing the embedded material to the base 70 and the lower member 30 is provided in the portion of the lower member 30 that is embedded in the embedded material of the base 70 and/or the other portion. It's also good.

10 and 11 show other aspects of the embodiment shown in FIGS. 6-8. The upper member 28 is rotatably supported by the lower member 30, and allows the inclination angle of the shaft 14 to be adjusted relative to the club head 12. Lower member 3
0 is pivotally coupled to the connecting member 52 and is adjustable in a direction perpendicular to the direction of adjustment by the upper and lower members 28,30.

The dovetail member 58, together with the slot 60 and adjuster 54, forms an attachment means for repositioning and attaching the shaft 14 longitudinally to the club head.

One or both of the facing surfaces of the adjacent upper and lower members 28 and 30 may be configured such that the upper and lower members can contact each other in alignment with a vertical plane, depending on the golfer's preference or to maintain the balance of the club head. , can also be adjusted by mechanical finishing. The upper and lower members 28, 30 are formed as a pair to accomplish the same purpose. Also small gap 72
is provided between the connecting member 52 and the upper surface of the club head 12, so that the rotation can be adjusted by the adjusting means 54. After making a predetermined adjustment, the small gap 72 is fixed by press-fitting silver solder or the like.

Also, in this embodiment, the connecting means 18 is closer to the club head 12 than in the previous embodiment.

The dovetail slot 60 may also be filled with any suitable member forming an extension of the bulbous portion 66 to increase the weight at the end of the club head 12. slot 6
0 may be fitted with an insert at its end. The head 12 is preferably manufactured by casting a rod 12 with a slot 60 extending near the end. club head 12
In order to balance the slot 1-60, inserts (not shown) are inserted into both ends of the slot 1-60. The insert has an inner end curved into an arc, and the dovetail-shaped slide piece 58 is
Therefore, by curving the outer end, the slide piece 5
8 can match the arcuate portion of the insert when located at the end of the slot 60.

Further, the slide piece 58 can be moved into the slot 60 via the slot 73 extending from the slot 64. slot 7
3 serves to introduce more weight into the slot 60 to balance the club head 12.

Further, as shown in FIG. 10, a reverse striking portion 74 is provided on the lower back surface of the club head 12, and the reverse striking portion 74 is
The golf ball has a hitting surface that allows the golf ball to be hit high in the opposite direction to avoid a penalty stroke when the golf ball is placed in a difficult position where a golfer cannot hit the ball forward.

The present invention can provide a golf aid that golfers can try out in order to find the appropriate weight, length, etc. Golfers can record their unique configurations, and manufacturers can create custom clubs accordingly.

If desired, the connecting means can be used to create a mold for molding the portion of the golf club. Instead of molding, it can also be manufactured by machining. The golf aid can also be used as a golf club in its own right by enclosing various adjustment parts. It is clear that the same golf aid can be used for right-handed and left-handed players. It is also clear that the various adjustment mechanisms facilitate finding a club head with a favorable balance for the golfer.
