Description

FIELD OF THE INVENTION

The present invention relates generally to an apparatus and method for practicing the sport of golf. More specifically, it relates to an apparatus and method for recording the location of impact between a golf ball and the face of a golf club during a golf swing.

BACKGROUND OF THE INVENTION

Generally speaking, it can be said that each golf club has a “sweet spot” for striking a golf ball. The sweet spot is typically located at or near the center of the face of the golf club and defines the location on the face of the golf club where it is most desirable to make contact with the golf ball during the golf swing. Striking the golf ball at the sweet spot generally results in the best overall trajectory, distance and direction of flight for the golf ball.

A variety of factors contribute to the proper execution of a golf swing. These factors include the stance assumed by the golfer, the distance between the golfer and the golf ball, the balance of weight assumed by the golfer, the golfer's grip on the golf club, the rotation of the golfer's shoulders and hips, and the speed and path of the back-swing, the down-swing and the follow-through swing. Each of these factors ultimately affects the manner in which the golf club makes contact with the golf ball, including the location of impact between the golf ball and the golf club. A properly executed golf swing will generally result in the golf ball impacting the face of the golf club at or near the sweet spot.

Golfers typically perfect their golf swing by taking golf lessons or through practice and repeated trial and error. Providing the golfer with proper feedback regarding the location of impact between the golf ball and the face of the golf club during these practice sessions enables the golfer to adjust his or her stance, swing and/or grip to insure that the golf ball strikes the face of the golf club at or near the sweet spot. It is desirable, therefore, to provide accurate feedback to the golfer regarding the location of impact between the golf ball and the face of the golf club so that the golfer can make the proper adjustments to his or her golf swing.

Numerous devices and systems for providing such feedback are known in the prior art as evidenced by U.S. Pat. No. 5,779,556 issued to Cervantes et al. on Jul. 14, 1998; U.S. Pat. No. 5,142,309 issued to Lee on Aug. 25, 1992; U.S. Pat. No. 5,033,746 issued to Jones on Jul. 23, 1991; U.S. Pat. No. 4,974,851 issued to Closser et al. on Dec. 4, 1990; U.S. Pat. No. 3,806,132 issued to Brandell on Apr. 23, 1974; U.S. Pat. No. 3,754,764 issued to Manheck on Aug. 28, 1973; and U.S. Pat. No. 2,660,436 issued to Gorssman on Nov. 24, 1953.

These known prior art systems suffer from one or more deficiencies, however. For example, many of these prior art systems are complex in that they are comprised of numerous layers of different materials. Some, for example, include wax or waxy layers that may, under force, slip or move out of position and whose properties may change in very warm or very cool weather. Others include one or more layers of paper or paper by-products that can easily tear during impact or be damaged by moisture or water. Finally, others include smooth outer plastic layers designed to protect the inner waxy or paper layers. The outer plastic layers tend to have relatively low coefficients of surface friction. The smooth plastic outer layers, therefore, may not accurately replicate the grip that the club face would have had on the ball in the absence of the recording device.

Another problem with these prior art devices relates to re-usability. Most of the prior art devices are designed to be used once, or at most, only a few times before they must be replaced. In all but one of these prior art systems, the mark or image left by the golf ball cannot be erased and repeated use of the recording device results in multiple marks being left on the recording device. The one prior art device that does provide for erasure of the mark left by the golf ball (see U.S. Pat. No. 5,033,746) suffers from the other drawbacks discussed above.

It is desirable, therefore, to have a recording device that is simple in construction yet rugged enough to handle the forces imparted by a golf ball during impact with a golf club. It is also desirable to have a recording device that can tolerate moisture and changes in temperature without effecting performance. It is also desirable to have a recording device that has a contact surface with a coefficient of surface friction that can accurately replicate the grip that a golf club puts on a golf ball. Finally, it is desirable to have a recording device that can be used over and over again, both in terms of its lasting durability and in terms of its ability to provide for the erasure of earlier impact marks and images.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

While the present invention will be illustrated with reference to a particular golf ball impact recording apparatus and method having a particular configuration and particular features, the present invention is not limited to this configuration or to these features and other configurations and other features can be used. Also, although the present invention will be illustrated with reference to the sport of golf, the present invention is not limited to the sport of golf and may have application in other sports and in other activities as well. [0027]
Generally, the present invention involves an apparatus and method for recording the location of the point of impact between a golf ball and a golf club during a golf swing. According to one embodiment, the recording device includes a napped or piled surface comprised of a plurality of hairs or fibers on the front side of the recording device. An adhesive material is included with, or applied to, the back side of the recording device. The recording device is sized-to-fit on the face of the golf club and is attached to the golf club face using the adhesive material. [0028]
The napped surface is a sueded surface made from cowhide in one embodiment. In other embodiments, the recording member is made from other types of natural or man-made materials, including man-made sueded materials. The end result is that recording devices made from these types of materials are extremely durable and can survive scores of impacts without tearing or damage. Furthermore, the napped surface of these recording devices tend to have a higher coefficient of surface friction than is exhibited by known prior art recording devices. Thus, recording devices in accordance with certain embodiments of the present invention will more accurately replicate the grip imposed upon the golf ball by the golf club than do the known prior art devices. [0029]
Prior to impact with the golf ball, the hairs or fibers on the napped surface of the recording member are generally all or substantially all raised and oriented in the same or substantially the same general direction. Upon impact with the golf ball during the golf swing, the hairs or fibers at the location of impact are immediately compressed and become disoriented or misaligned with respect to each other. The compression and/or misalignment of the fibers at the point of impact changes the texture of the napped surface at that point. The change in texture leaves a distinct and visible mark (in some cases, an actual image of the ball is left) on the recording device (e.g., on the napped surface) at the location of impact. Thus, by simply viewing the napped surface of the recording member after impact, the location at which the golf ball impacted the face of the golf club can be easily determined. [0030]
The napped surface of the recording member tends to retain its character after impact and thus the mark left by the golf ball at the impact location will generally remain on the napped surface until it is removed or erased by the golfer. Removal of the mark is accomplished in one embodiment of the present invention by simply brushing the napped surface of the recording member to raise the nap at the location of impact. The brushing action raises the nap to its original pre-impact condition and the mark is thereby erased. The recording member is now ready for re-use. [0031]
Because the recording device is durable and erasable, it can be used repeatedly. For example, the recording device can be used over and over again during any single practice session simply by erasing the earlier marks that appear on the napped recording surface. Furthermore, because of its durability, the recording device of the present invention can be removed from the face of one golf club and affixed to the face of another golf club or it can be stored for use on another day. [0032]
Referring initially to FIG. 1, a [0033] recording device 10 according to one embodiment of the present invention is shown attached to a golf club head 12 of a golf club 14. More specifically, recording device 10 is shown attached to the face 16 of golf club head 12. Although the particular golf club shown in FIG. 1 is a “wood” (also called a “driver”), the use of a wood in the figures is for illustrative purposes only. It should be understood that the recording device of the present invention can be used with other types of golf clubs having other shapes and sizes, including irons, wedges and putters.
Recording [0034] device 10 is oval in shape in the embodiment of FIG. 1 and is sized-to-fit on face 16 of golf club 14. Sized-to-fit, as used herein, means that the recording member is sized-to-fit on the face of a golf club. It should be noted that the present invention is not limited to this particular size and other sizes of recording devices could be used. In other embodiments, for example, the recording member covers more or less of the face of the golf club than does the recording device shown in FIG. 1. It should also be noted that the present invention is not limited to the particular oval shape shown in FIG. 1 and other shapes could be used including circular, square, rectangular, trapezoidal, or even irregular shapes.
Recording [0035] device 10 is comprised of a recording member 18 having a central aperture 20 in this embodiment. Aperture 20 is positioned in FIG. 1 at the approximate location of the sweet spot of golf club 14. Central aperture 20 is included in this embodiment to allow the golf ball to directly contact the sweet spot on the face of the golf club without any interference from the recording device. In this embodiment, the diameter of aperture 20 is approximately 0.8 inches. In other embodiments, aperture 20 is larger or smaller than 0.8 inches and may be positioned at a location other than the sweet spot. It should be noted that the inclusion of an aperture on recording device 10 is not required and in other embodiments of the present invention, no aperture is provided or more than one aperture is provided.
As shown in FIG. 4, [0036] recording member 18 includes front and back opposing sides or surfaces 22, 24 respectively. The front surface 22 of recording member 18 is a napped or piled surface comprised of a plurality of hairs or fibers 26. Nap or napped surface as used herein means a hairy or downy surface. Pile or piled surface, as used herein means a surface of usually short, close, fine furry hairs or fibers. Hair as used herein means a slender threadlike outgrowth and includes both natural and man-made hairs and hair-like structures. Fiber, as used herein, means a thread or a structure or object resembling a thread and includes both natural and man-made fibers.
It should be noted that the relative dimensions of the various layers depicted in FIG. 4 (and in FIGS. 6 and 7) are not to scale, but are rather for illustrative purposes only. [0037]
In one embodiment, [0038] recording device 18 is treated by chemical or other means to increase its water or moisture repellence. In other embodiments, no such treatments are provided.
The [0039] back side 24 of recording member 18 includes a layer of adhesive material 28 in this embodiment. The adhesive material in this embodiment is a releasable adhesive material such as is used with removable labels. Adhesive material 28 is used to affix recording device 10 to the face of golf club 14.
When not in use, [0040] recording device 10 is stored attached to a carrier or backing material 30, such as paper or plastic, to prevent the adhesive layer 28 of recording device 10 from adhering to unintended objects. Carrier 30 is of such a nature that recording device 10 can be easily removed from carrier 30 without damaging adhesive layer 28.
In one embodiment, for example, [0041] carrier 30 is made of plastic and is similar in size, shape and thickness to a credit card. This allows recording device 10 to be easily carried inside of a golfer's wallet or purse. Recording member 18 is releasably affixed to the front side of carrier 30 and instructions for using recording device 10 are printed on the back side of the credit card sized carrier 30.
It should be noted that [0042] carrier 30 is not limited to being credit card sized and other sizes of backing carriers can be used. Likewise, more than one recording member 18 can be mounted to a single carrier. In other embodiments, for example, carrier 30 is a sheet of material and two, four or eight recording members are mounted on a single backing carrier 30.
In another embodiment, a brushing device or brushing [0043] member 42 is mounted on the back side of carrier 30 for use in erasing the impact mark left by the golf ball on napped surface 22. For example, brushing member 42 is the “hook” half of a hook and loop type fastener, one type of which is commonly known as “Velcro” in one embodiment. Brushing member 42 includes an adhesive backing material and is affixed to one corner of carrier 30 in this embodiment. In other embodiments, no brushing member is provided on carrier 30 or the brushing member is mounted at a different location on carrier 30.
Napped or piled [0044] recording surface 22 exhibits several useful properties or characteristics that enable recording device 10 to record the impact location of a golf ball with a golf club in this embodiment. Normally, the hairs or fibers that form the nap or pile on surface 22 are raised such that all or substantially all of the hairs or fibers are standing upright or substantially upright (uncompressed and un-matted) and/or are generally uniform and aligned or oriented in the same or substantially the same direction.
Now, when an object touches or impacts raised nap or pile [0045] surface 22, the hairs or fibers 26 at the location of impact are compressed or matted down and are no longer aligned or oriented with each other. The texture and light reflecting properties of the material at the location of impact is changed such that a visible mark (or in some cases, an image) is left on the napped surface at the location of impact.
It should be noted that ball marks will generally be perceivable (e.g., visible) on the napped recording surface of the present invention when the height, texture and/or general directional orientation of the hairs, fibers or strands that make up the napped surface at the location of impact differ from the height, texture and/or general directional orientation of the hairs, fibers or strands located on the balance or remainder of the napped surface. Anyone who has drawn his or her finger across the surface of a suede jacket, for instance, has seen this same type of effect in the nature of a line left on the jacket's surface. Similarly, anyone who has walked across freshly vacuumed carpet has seen this effect in the nature of the footprints that are left behind on the surface of the freshly vacuumed carpet. [0046]
Another useful property of some napped or piled surfaces is that the image left by touching or impacting the napped or piled surface tends to remain on the surface. In other words, the surface has memory. The image or mark left on the surface can generally be removed by raising the nap or pile at the location of the touch or impact. Thus, a mark or image left on a napped or piled surface is generally visible until it is erased or removed. [0047]
The mark can be erased simply by brushing, stroking, sweeping or abrading the napped or piled surface to once again raise the nap at the location of impact. It should be noted, however, that different napped or piled materials exhibit different properties with respect to how long a mark will last and in some cases, the pile or nap may return to its raised condition on its own without the need for brushing, sweeping, or stroking of the napped or piled surface. [0048]
Various materials have napped or piled surfaces that exhibit the properties and characteristics described above and can therefore be used for recording [0049] member 18. In one embodiment of the present invention, for instance, the napped surface 22 is a sueded surface (leather with a napped surface) formed from animal hides. Various types of animal skins and hides can be used to obtain a sueded or napped surface including, without limitation, cowhide, split cowhide, calfskin, kidskin, lambskin, goatskin, pigskin, and deerskin. The sueded or napped surface is typically produced by buffering the flesh side of the hide or skin to raise a velvet-like nap on the surface. The sueded surface may also be produced on the grain side (the outside surface) of the hide or skin, however this is less common.
In addition to natural animal hides, the napped [0050] surface 22 of recording member 18 can also be formed from man-made materials. For instance, many man-made suede-like materials are available that replicate the look and feel of suede. These materials are known by various names including “suede cloth,” “faux suede,” “Ultra Suede.,” Every-day Suede,” “Microfiber Suede,” and “Jasper Suede.” These man-made suede-like materials are generally made from 100% polyester or nylon/polyester blended yarn that is spun into micro fiber-like fabric. The fabric is brushed with pins or wires to raised the nap and achieve a suede-like touch or feel to the hand. Finally, the fabric is sheared to give it a suede-like look and texture.
In addition to the man-made suede-like materials discussed above, the napped [0051] surface 22 of recording device 10 can also be formed from other man-made materials including other textile and fabric materials, such as velvet, velour, and corduroy for instance. In general, it should be understood that the recording member 18 is not limited to being made from the natural or man-made materials discussed above. Those materials are listed here for illustrative purposes only. The napped and piled surfaces of the present invention can be formed from any material, natural or man-made, that includes a napped or piled surface that can record an image by matting or compressing the hairs, fibers or strands that form the napped or piled surface.
The [0052] back surface 24 of recording member 18 is configured for attachment to the face of a golf club (see FIG. 4). In one embodiment, for example, an adhesive material, such as a releasable or repositionable adhesive 28, is disposed on back surface 24 of recording member 18. The releasable adhesive is provided to secure recording device 10 to face 16 of golf club 14. Using a releasable or repositionable adhesive allows recording member 10 to remain fixed in place on face 16 during usage and still allows for recording member 10 to be easily removed from face 16 after usage without leaving any adhesive residue behind on face 16.
A portion of the [0053] back side 24 of recording member 18 does not include adhesive in one embodiment. This portion is left without adhesive material to facilitate easy removal of the recording device from the face of golf club 14. For instance, the entire outer perimeter of the back side 24 of recording member 18 does not include any adhesive in one embodiment. In another embodiment, one end of the back side 24 of recording member 18 does not include adhesive.
Releasable adhesives of the type discussed above are well known and can take the form of the tacky material used with known removable labels or can take the form of a double-sided tape for instance. Other types and forms of releasable, repositionable, and permanent adhesives are used in other embodiments. Adhesive or adhesive material, as those terms are used herein, include all types of adhesives including glues, tapes, etc. . . . . [0054]
In an alternative embodiment of the present invention, no adhesive is provided on the [0055] back side 24 of recording member 18. Rather, the back side is configured to receive an adhesive and the adhesive is actually applied by the golfer just prior to mounting of the recording member on the face of the golf club.
Another alternative embodiment of the present invention is shown in FIG. 7. A [0056] recording device 100 includes a recording member 118 in this embodiment. The front side of the recording member includes a napped or piled surface 122 having a plurality of hairs or fibers 126. A permanent adhesive material or layer 140 is applied to the back side 124 of recording member 118. The front side of a carrier member 138 is then attached to the back side 124 of recording member 118 using permanent adhesive 140. A releasable adhesive layer 128 is attached or applied to the back side of carrier member 138 for use in attaching recording device 100 to the face of a golf club. When not in use, recording device 100 is stored attached to a backing material 130 to prevent the releasable adhesive layer 128 from adhering to unintended objects. Backing material 130 is of such a nature that recording device 100 can be easily removed from backing material 130 without damaging adhesive layer 128.
Another alternative embodiment of the present invention shown in FIGS. 5 and 6 includes a protective layer of transparent or [0057] translucent material 36 positioned over the napped surface 22 of recording member 18. The protective layer 36 is used in this embodiment to protect recording member 18 and napped surface 22 from the potential deleterious effects of moisture, sand, dirt or other debris that may be present during a golf swing. In this way, the napped recording surface 22 of recording member 18 remains unsoiled.
The [0058] protective layer 36 in this embodiment is attached to the recording member using a releasable adhesive (not shown). Protective layer 36 can be easily removed, therefore, to allow napped surface 22 to be inspected and brushed after each use. The protective layer 36 is then replaced over napped surface 22 prior to re-use of recording device 10.
In yet another embodiment of the present invention shown in FIG. 7, a [0059] recording device 100 includes a recording member 118. The front side of recording member 118 includes a napped or piled surface 122 having a plurality of hairs or fibers 126. A permanent adhesive material or layer 140 is applied to the back side 124 of recording member 118. The front side of a carrier member 138 is then attached to the back side 124 of recording member 118 using permanent adhesive 140.
A releasable [0060] adhesive layer 128 is attached or applied to the back side of carrier member 138 for use in attaching recording device 100 to the face of a golf club. In this embodiment, therefore, the releasable adhesive is not applied directly to back side 124 of recording member 118, but rather is applied to carrier member 138. This configuration may be desirable, for instance, if back side 124 of recording member 118 is not suitable for the application of a releasable adhesive.
When not in use, [0061] recording device 100 of FIG. 7 is stored attached to a backing material 130 to prevent the releasable adhesive layer 128 from adhering to unintended objects. Backing material 130 is of such a nature that recording device 100 can be easily removed from backing material 130 without damaging adhesive layer 128.
The method for using the present invention to record the impact location of a golf ball with the face of a golf club will now be described in detail (see FIGS. 2 and 3). To begin with, the golfer removes the [0062] backing material 30 from recording device 10 and affixes recording device 10 to the face 16 of golf club 14 using the adhesive material 28. If recording member 10 does not include an adhesive material on its back side, the golfer simply applies adhesive material to the back side 24 of recording member 18 prior to application of recording device 10 on the face of golf club 14.
If a [0063] central aperture 20 is provided on recording device 10, the central aperture is centered over the approximate sweet spot of the golf club. The sweet spot will generally be located in the center of the face of the golf club. Properly mounted and affixed, the back side 24 of recording member 18 is facing the face 16 of golf club 14 and the front napped surface 22 is facing away from face 16 of golf club 14.
With [0064] recording device 10 affixed to golf club 14, the golfer now brushes, sweeps or strokes napped surface 22 to raise the nap on the entire surface 22 of recording member 18. If a clear protective layer 36 is provided over recording member 18, the golfer must first lift or remove the protective layer before brushing the napped surface. After the nap on napped surface 22 has been raised, the clear protective layer, if present, is replaced over recording member 18. Recording device 10 is now setup to record the impact location of the golf ball with face 16 of golf club 14.
The golfer now takes a practice swing. Upon impact with the face of the golf club, a mark or image [0065] 32 (see FIG. 2) is left on napped surface 22 of recording device 10 by the golf ball. The golfer can now view the location of mark 32 on recording device 10 to determine where on the face of the golf club the golf ball impacted the golf club. This information, combined with the observed distance and trajectory of the golf ball, may provide useful information to the golfer that will enable the golfer to adjust his or her stance, grip and/or swing to improve his or her golf shot.
The [0066] mark 32 made by the golf bail on napped surface 22 of recording device 10 will generally remain on the napped surface until erased. Therefore, before taking another golf swing, the golfer may elect to erase the previous mark from recording member 18. This is accomplished in one embodiment by simply brushing napped surface 22 with a brush 34 (see FIG. 3) to raise the nap at the location of impact. Raising the nap at the location of impact erases mark 32 from recording device 10. Recording device 10 is now ready to be used for recording the next location of impact during the next golf shot.
Alternatively, if the golfer so desires, he can leave the [0067] previous mark 32 on recording member 18 and take one or more additional shots. Eventually, however, as napped surface 22 fills up with marks, it will be desirable for the golfer to brush the napped surface to remove all marks left by the golf balls. The golfer can decide whether he or she wants to do this after each golf shot or only after several golf shots have been made.
If at some point during the practice session, the golfer decides to practice with a different golf club, the golfer can remove [0068] recording device 10 from the face of the first golf club and affix it to the face of the new golf club. Alternatively, if the practice session is complete, the golfer can simply remove recording device 10 from the face of the first golf club and re-affix it to backing material 30 for use on another day. In this way, recording device 10 can be reused numerous times until the releasable adhesive degrades to the point where it can no longer be used to properly affix recording member 10 to the face of a golf club. At this point, a new recording member may be used. Alternatively, if recording member 18 is still usable, the golfer may decide to simply apply new adhesive to the back side 24 of recording member 18 and continue to re-use it until recording member 18 itself wears out.
Numerous modifications may be made to the present invention which still fall within the intended scope hereof. Thus, it should be apparent that there has been provided in accordance with the present invention an apparatus and method of recording the impact location of a golf ball upon a golf club that fully satisfies the objectives and advantages set forth above. Although the invention has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to embrace all such alternatives, modifications and variations that fall within the spirit and broad scope of the appended claims. [0069]
