Abstract
A putter trainer includes a core having an elevated central region; and a cover having an opening adapted to engage the elevated central region.
Description
- This application claims priority to Provisional Application Serial No. 60/347,727, filed on Jan. 11, 2002, the content of which is hereby incorporated-by-reference.
- 1. Field of the Invention
- The present invention relates to golf instructional or training devices and, more particularly, to golf training devices that are user-mountable on putters.
- 2. Description of the Prior Art
- In the game of golf, a putting stroke is used with a golf club to roll a golf ball across a putting green into a hole. The success of the stroke depends on the alignment of a club face of the golf club at impact, the direction of movement of a club head of the golf club at impact, and the speed of the club head at impact. To improve putting proficiency, the golfer must adopt and learn a consistent and reproducible putting stroke, including controlling the alignment of a putter's club face and the direction of movement of a club head at the point of impact in a consistent manner. One effective putting stroke provides a pendulum-like motion in which the golfer's arms move together, the pendulum-like motion originating in the golfer's shoulders. Generally, the larger shoulder muscles of the upper body are much more controllable than the smaller arm muscles and, therefore, provide better control of the putting stroke.
- As discussed in U.S. Pat. No. 5,527,041, a variety of devices have been developed to assist the golfer in aligning the golfer's feet and club head as well as devices to help groove the proper swing path. One category of such devices includes those with one or two guide rails placed adjacent to the golf ball. The golfer can stroke the club along the guide rails to practice a straight-back and straight-through putting stroke. Unfortunately, the guide rails are not typically adjustable in their spaced-apart positions from each other. Such adjustment is desirable because golf clubs, particularly putters, come in a variety of differently-sized dub heads. In order to tightly constrain the moving club head to be between the two guide rails, it is necessary to provide adjustability of the positions of the guide rails. A device which does provide adjustable guide rails involves loosening a screw and adjusting a housing relative to another housing and then re-tightening the screw.
- Other devices which assist the golfer in the alignment of the club head have included laser light sources associated with the golf club and indicating the direction in which the club face is pointed. Each of the devices either requires a specialized, custom putter incorporating the device or requires a modification or attachment to the golfer's own putter. Such devices do not accommodate the golfer's desire to practice with their own putter in an unmodified fashion. Golf clubs, and particularly putters, come in a variety of lengths, weights, and distributions of weight along the golf club. Further, the shape of the club head provides an aesthetic appearance which may instill confidence in the golfer. These factors cause a golfer to become comfortable with their own putter and less likely to use or feel comfortable with a specialized, custom putter or even with their own putter if modified to change the appearance, shape, and/or weight distribution.
- The present invention is, of course, described in the claims. Briefly, however, the invention provides a putter trainer that includes a core having an elevated central region; and a cover having an opening adapted to engage the elevated central region. Implementations of the putter trainer may include one or more of the following. The core may include one or more grooves and the cover may include one or more corresponding projections adapted to engage the grooves on the core. The cover may include one or more surface recesses. The cover may include one or more concave dot pattern on the surface of the cover. A horizontal and vertical cross pattern may be formed on the surface of the cover to create a visual alignment system. An adhesive layer may be positioned on a rear surface of the core. The adhesive layer may be glue or wax. The size of the elevated central flat region may be changed to accommodate golfer skill. The core may be injection molded and may be polypropylene. The cover may be transfer molded onto the core and may be sanaprene. The central flat region may have a shape selected from one of the following: circle, square, triangle, rectangle, and octagon. The core may have a substantially circular base and the cover may have a substantially semispherical shape. The core may be a cone and wherein the elevated central region may be rounded.
- In another aspect, a putter trainer includes a core having an elevated central region; one or more grooves on the side of the core, one or more concave dot pattern on the surface of the cover, and a horizontal and vertical cross pattern on the surface of the cover, wherein the concave dot pattern and the cross pattern forms a visual alignment system. The trainer also includes a cover having an opening adapted to engage the elevated central region and one or more corresponding projections adapted to engage the grooves on the side of the core.
- Implementations of the above aspects may include one or more of the following. The core and the cover may be made from different material to sound and feel differently when they make contact with the ball. When a ball strikes the core, a crisp, solid feel and click are generated and when the ball strikes the cover, a different feel and sound are generated.
- Advantages of the invention may include one or more of the following. The training device is inexpensive while achieving its desired results. Since the golfer can attach the trainer to his/her own putter, there is no need for a separate device that has a completely different feel than the golfers own putter—the device is used with a golfer's own equipment and thus can be used under the same conditions the golfer faces on the golf course. The device is small, easy to transport and nearly indestructible. It is easy to use: the golfer simply presses it onto the face of the putter, centering it on the “sweet spot”. It takes only seconds to ready the device for use or remove it for storage. The device is small enough to fit in the golfers pocket and can be used anywhere. The device can be used at the golf course and stored in the golfer's bag, eliminating the inconvenience of a larger device that, under the rules of golf, cannot be carried in the golfer's bag during play. The device requires minimal care and virtually no upkeep since it is reusable and ultimately disposable.
- With the trainer attached to the putter, the golfer simply makes his/her natural putting stroke. The device also provides instant feedback on the putting stroke to the golfer. The feedback from the device indicates the position of the putter face as it strikes the ball. Depending on the direction the ball travels after it has been struck, the golfer can determine exactly where on the putter face the ball was struck, the swing plane of the putter prior to striking the ball and whether or not the face of the putter is square to the line of the putt. With this knowledge, the golfer can acquire a “feel” for a consistent, solid putting stroke.
- The device also provides more distinctive feedback than other devices. Aside from the advantage of using the golfer's own putter to maintain consistent feel, the two types of plastic used to construct the device both sound and feel differently when they make contact with the ball. The hard core, when struck precisely, gives off a crisp, solid feel and click. When the ball is miss-hit and it makes contact with the soft outer shell, the feel and sound are decidedly different than a solidly struck ball.
- Further features of the training device will be clear to those skilled in the art from a review of the following specification and drawings, all of which present a non-limiting form of the invention. In the drawings:
- FIG. 1 shows an exemplary set of three training devices.

- The above training devices may be secured to the face of the putterhead by a variety of means, such as by adhesion or friction. The training can also be secured by press fitting. The training device can have a back face that is in contact with the face of the putter. The “touch and the feel” of the putter may be altered by varying the amount of material of the
device 100. - Turning now to FIG. 6, a golf club210 has a
shaft 212 attached to aclub head 214. A putter-type club head is shown in FIG. 6, however, as explained herein, other club head types, such as irons or woods, may also be prepared. Theclub head 214 has ahosel 216 that accepts theshaft 212 with a heel 218 at the hosel end of theclub head 214 and atoe 220 opposite of the heel 218. Theclub head 214 also has a sole portion 226 and an oppositetop portion 228. Extending between theheel 214 and thetoe 220 is astrike face 222, which is the surface that used to contact a golf ball 223 upon impact between the golf club 210 and the ball 223. Thestrike face 222 includes a “sweet spot,” or the center of gravity in the toe to heel direction, on which is mounted thetraining device 100 of FIG. 1. Thedevice 100 is made of a material that is different than the rest of the club head. - In the present invention, golf ball is struck. Impact forces are dampened and transferred radially, in directions perpendicular to axis from core perimeter surface through the interface surface of the cavity to the surrounding putter body. The result is that, should the putter face strike the golf ball outside of the preferred strike regions, the dampening effect is diminished when compared with striking the golf ball within the preferred region. It is the reduction of vibrations and or resonating frequencies afforded through radial dampening and the resultant improved ball response and sound made by the strike that results in what golfers describe as a “softer feeling” putter. Feel, as relating to golf, can be described as the resonance or vibrations audibly transmitted to the golfer, and tactilely transmitted through the shaft and grip to the golfer's hands, caused by impact between the club face, golf ball, and in some instances the turf or other foreign obstacles. Feel may further be described as a flexation or twisting torque applied to the shaft during the swing or putting stroke at any point including impact. Feel, in other words, is the feedback to the golfer whether auditory or tactile.
- The
core 110 communicates with the surrounding body of the putter in an evenly radially distributed fashion through its perimeter or outer surface. This better communicates to the golfer information about how a golf ball was struck. This allows the golfer to make the necessary adjustments to improve his or her putting stroke. - It should be understood that one of ordinary skill in the art can prepare any size or shape of putting trainer in accordance with the present invention, and attach the trainer to any type of club. For example, a substantially rectangular shaped trainer can be prepared, preferably rectangular. “Substantially rectangular” means a shape that will fill a significant portion of the striking face of a club. Preferably, the club is an iron or a putter. More preferably, the club containing the device is a putter. It should also be understood by one of ordinary skill in the art that multiple trainers can be used in a club, so long as at least one such trainer is prepared according to the teaching herein.
- Additionally, instead of being glued to the putter, the training device can be releasably secured to putter face by a pair of headed screws inserted through a pair of longitudinally disposed, laterally spaced apart holes. Screws can be threadingly secured by and tightened into threaded backing plate holes, thereby securing the
device 100 to the putter head. - It will additionally be recognized that the present invention contemplates the use of differing training devices to in effect, modify the feel and operating characteristics of the putter head. In this regard, when desired, more resilient polymer materials can be utilized for the cover and the core. Alternatively when desired, hard material can be utilized to enable customized performance characteristics.
- Variations in the invention are possible. Thus, while the invention has been shown with three embodiments, it is not so limited but is of a scope defined by the following claim language which may be broadened by an extension of the right to exclude others from making, using or selling the invention as is appropriate under the doctrine of equivalents.
- As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention without departing from the spirit or scope thereof. Accordingly, the scope of the invention is to be construed in accordance with the substance defined by the following claims.
