[0031] Well-known functions or constructions may not be described in detail for brevity and/or clarity.

[0032] Referring now to the figures, a putting practice device, designated broadly at 5, is shown in FIGS. 1-4. The device 5 includes an elongate base 10 and a detachable elongate rail 40. These components are described in greater detail below.

[0033] The base 10 is illustrated as formed as a unitary member (typically wood or plastic). The base 10 has a horizontal flat bottom surface 20 and an upper surface 30 that runs such of the length of the base 10. The upper surface 30 is typically inclined (e.g., approximately 0.5-3.0 degrees) upwardly from the near end 11 to the far end 12 relative to the bottom surface 20. The base 10 includes a channel 14 that extends much of the length of the base 10. In some embodiments, the base 10 is about 24-60 inches in length and about 3-6 inches in width, and varies in thickness from about 0.1-0.3 inch at the near end 11 to 0.5-1.5 inches at the far end 12. The channel 14 may be between about 0.060 and 0.250 inch in depth, and may be sized in length and width to receive the rail 40 as described below.

[0034] At the near end 11 of the base 10, an open-ended tapered inlet 50 extends toward and merges with the channel 14 (see FIG. 3). At its narrowest point, the inlet 50 is narrower than the channel 14. At its widest point at the near end 11, the inlet 50 is typically between about 2-4 inches in width, and is greater in width than a golf bail. At its opposite, tapered end, the inlet 50 is typically between about 0.375-0.600 inch. In some embodiments, the area around the inlet 50 may include visual indicia (e.g., one or more straight lines) that indicate the proper swing path for the putter.

[0035] The base 10 also includes a perimeter fence 70 which comprises a raised wall extending upwardly from the upper surface 30 and mounted around the perimeter of the base 10. The fence 70 is typically approximately 0.125-0.5 inch wide and 0.050-0.75 inch in height. In some embodiments the fence 70 increases in height toward the far end 12 of the base 10, with a height of approximately 0.375 inches at the rear end 12 being typical. The fence 70 ordinarily bounds a major portion of the periphery of the base 10, including the side edges and the target area 90 (see below).

[0036] A target area 90 is positioned at the far end 12 of the base 10 (see FIG. 4). The target area 90 is typically sized to approximately simulate the size of a golf hole. In some embodiments, the target area 90 may include some visual indicia, such as a circle that simulates a golf hole. Alternatively, the target area 90 may include interchangeable inserts, such as a product logo, the name of a golf club or resort, or the like.

[0037] The target area 90 is guarded by two wedge-shaped gates 80 that extend inwardly from the fence 70 and reduce the width of entry into the target area 90. The gates 80 are typically the same height as the fence 70.

[0038] FIG. 1 also illustrates the rail 40. The rail 40 includes a near end 41 and a far end 42. A planar upper surface 43 extends from the far end 42 to an inclined section 44 at the near end 41. As can be seen in FIG. 2, the rail 40 is received in the channel 14 of the base 10. In one embodiment, the rail 40 is between about 16-40 inches long, between about 0.25-2.0 inches wide, and between about 0.06-0.5 inch thick.

[0039] The rail 40 can be formed of any number of materials, including plastic, metal, wood or the like. In some embodiments, the upper surface 43 of the rail 40 is very smooth. The smooth finish reduces friction between the golf ball and the insert upper surface 43. Because the golf ball is being propelled forward, surface friction, which would cause the bail to drag opposite the direction of movement and impart forward spin on the golf ball that would reduce or eliminate any side spin, is minimized.

[0040] Referring now to FIG. 2, therein the base 10 and rail 40 are assembled to create the device 5. As can be seen in FIG. 2, the rail 40 is inserted into and nested within the channel 14 of the base 10, with the near end 41 of the rail 40 being positioned adjacent the near end 11 of the base 10 (typically positioned about 2-5 inches away), and the far end 42 of the rail 40 positioned adjacent the far end 12 of the base 10. As can be seen in FIGS. 2 and 5, the upper surface 43 of the rail 40 extends above the upper surface 30 of the base 10 and is generally parallel thereto; in some embodiments, the upper surface 43 extends between about 0.050 and 0.250 inch above the upper surface 30. However, as can be seen in FIG. 3, the lower portion of the inclined section 44 dips below the upper surface 30 (typically approximately 1/32- inch). Thus, the end of the inclined section 44 and the near end of the channel 14 form a depression that serves as a locating feature 60 for a golf ball. In some embodiments, the locating feature 60 is between about 24-54 inches from the target area 90.

[0041] Referring still to FIG. 2, use of the device is illustrated therein. A golf ball 1 is shown in broken line in a waiting position in the inlet 50, and being moved to a starting position in the locating feature 60 ready for putting (in solid line). In use, a golfer places the golf ball 1 in the inlet 50 such that it can be rolled into a consistent, secure, starting position in the locating feature 60. Because the inclined section 44 of the rail 40 is angled slightly with respect to the locating feature 60, the ball 1 is accurately held in a controlled, repeatable location in the device 10. In some instances, the golfer can position the golf ball 1 by simply using a putter to sweep or drag the golf ball 1 up the inlet 50, which lifts the ball 1 onto the upper surface 30 and deposits it at the locating feature 60. This technique can enable the golfer to deposit the ball 1 in the locating feature 60 without having to bend over.

[0042] Once the golf ball 1 is in the starting position, the golfer attempts to putt the golf ball with sufficient accuracy and speed so that it travels up and along the upper surface 43 of the rail 40 and reaches the far end 42 of the rail 40 and, without hitting the hole gates 80, ends up in the target area 90.

[0043] Because the upper surface 43 of the rail 40 is above the upper surface 30 of the base 10, the user will be able to tell when the golf ball 1 veers from the intended putting line, because the ball 1 will fall off of the rail 40, make a sound and travel sideways on the upper surface 30 of the base 10 toward the fence 70. If the ball 1 is hit with sufficient error that it would otherwise go travel off of the upper surface 30, the fence 70 acts to capture the ball 1. Whether the ball 1 is putted successfully to the target area 90 or falls off of the rail 40 before reaching the far end 42, the fence 70 will maintain the ball 1 on the upper surface 30. Because the upper surface 30 is angled slightly downwardly toward the near end 11, the golf ball 1 rolls back down the upper surface 30 toward the near end 11 of the base 10 and out of the inlet 50. The ball 1 can then be easily repositioned on the locator feature 60 to repeat the process.

[0044] Putts which are improperly hit tend to be associated with two types of putting stroke errors. The first type of error is major, and is caused when the putter face is not facing the hole at impact. The second type of error tends to be minor, and is caused when the putt swing path is not on the target line. Unless a putt is hit with sufficient precision to travel up the entire length of the rail 40, the ball 1 will fall off of the rail 40 on one side or the other. Once a ball 1 falls off of the rail 40, it is immediately clear that the putt was incorrectly hit, and the area where it falls off the rail 40 can provide immediate feedback related to the golf stroke error. Putts that quickly fall off of the rail 40 will likely be errors resulting from bad face angles. Putts that fall near the end of the rail 40 will tend to be putts where a combination of face angle and swing path both play a part (often resulting in side spin). It can be important that this sidespin is allowed to continue so the ball 1 can fall off of the rail 40 and be seen by the user.

[0045] When intervening turf has texture and is not smooth, sidespin is replaced with topspin due to the frictional drag caused by the ball-turf interface. One potential advantage of the present invention is the reduction and/or elimination of the intervening turf drag and corresponding isolation of sidespin, so that if sidespin is contributing to putting stoke error the effect will continue as far along as possible into the putt. This will increase the chances that the bail 1 will fall off the rail 40 even at the farthest point of the rail 40.

[0046] The thickness of the near end 11 of the base 10 is typically approximately 0.1-0.3 inch. This is a thickness that is generally low enough to avoid interfering with the position of the putter with respect to the floor or ground. If this thickness is too highfor example, using an extreme value of one inchthe putter height would be outside of a typical putting condition where the putter and ball rest on the ground level with the golfer's feet. Ideally, this thickness is as small as possible to make the feeling as close as possible to natural putting. However, a thinner dimension of the base 10 may negatively impact the strength and durability of the device 10. Thus, materials for the base 10 should be chosen accordingly.

[0047] In the illustrated embodiment, the fence 70 is shown to have a height of 0.250 inches near the near end 41 of the rail 40, which increases to 0.375 inches behind the target area 90. When a ball 1 rolls off of the rear end 42 of the rail 40, it typically has sufficient energy to continue to travel to the rear end of the fence 70. The height of the fence 70 may be selected such that, in order for the ball 1 to scale the fence 70 at this point, the ball 1 must have sufficient energy that it would likely skip over an actual golf hole. Therefore, when using the device 10, a golfer can learn to putt the ball with sufficient firmness to reach the hole, but not so hard as to skip over the hole on a typical green.

[0048] Those of skill in this art will appreciate that a number of variations to the device 10 may be employed. For example, the dimensions of components set forth above may vary in a number of different ways. Further alternative embodiments may include increasing or decreasing the diameter of the target area 90 and/or omitting the gates 80 or making them different in form and function.

[0049] Alternative embodiments of the configuration of the near end 11 of the base 10 may include slots or v-grooves that are used to urge or direct the ball 1 to the locating feature 60. With respect to the locating feature 60, a pair of slightly proud mounds in the base upper surface 30 may be used to hold the ball in position. Further provide positioning and retaining variations may also be employed. Also, swing correction devices, such as devices that direct or influence the putter head as the stroke is made, may be attached or affixed to this area of the device 5 to further assist the user in honing his/her stroke.

[0050] In still further alternative embodiments, the fence 70 at the far end 12 of the base 10 may be greater or lesser than 0.375 inches in height to match the energy requirement threshold of a ball to stay within the target area 90 due to variations in the hardness of the golf ball 1 and different surface cover materials. In some embodiments, the fence 70 may be adjustable in height to adapt to the desired speed of the putt.

[0051] In summary, the device 5 may be employed such that that a user hits a putt up the full length of the rail 40 such that it reaches the rail far end 42 and falls off onto the target area 90. If the putting line is incorrect, or if too much side spin is applied to the golf ball 1, the ball 1 will fall off the rail 40 before it reaches the target area 90. However, once the user achieves consistency in putting the entire length of a one-inch rail 40, the user has reduced his putting variance to approximately plus or minus 1 degree based on 27-inch rail 40. This improvement in putting precision may allow the golfer to consistently hole a level 9.6 foot putt on a typical putting green.

[0052] At this point, unless the user has a way to increase the putting difficulty, the user cannot improve his putting stroke by reducing putting stroke variance. The present invention may also, in some embodiments, provide a capability for the user to continue to increase putting precision. This may be achieved by replacing the standard rail 40 with rails of increasing difficulty.

[0053] FIG. 5A is a perspective view of the rail 40 in comparison to a second rail 140 shown in FIG. 5B. Both rails 40, 140 may have an identical overall length and identical starting ends; however, the second rail 140 has a decreased upper surface 143 on which the golf ball 1 can roll.

[0054] FIG. 6 shows a cross-section midway through rail 40. In FIG. 6 the rail 40 is divided into a top portion 40T and a bottom portion 40B, where the delineation between the two portions 40T, 40B is a horizontal plane which is at the same level as the upper surface 30 of the base 10. In contrast, FIG. 7 presents a reduced width rail 140 in which the top portion 140T is reduced in size and has the shape of a rectangle. The rail upper surface 143 may be smooth and flat, but because it presents a narrower putting surface, it will require more precise putting to achieve a successful putt the length of the entire rail 140. Like the bottom portion 408, the rail bottom portion 140B has the same cross-section as the channel 14. In some embodiments, the cross-section of the rail 140 may be generally trapezoidal (similar to that of the rail 340 discussed below), with flat or curved surfaces between the upper surface 143 and the side wails of the rail.

[0055] Intuitively it can be seen that the difficulty level of putting a golf ball along the reduced width rail 140 is more difficult than putting along the standard rail 40. By narrowing the rail upper surface, not only must the stroke direction be along the target line, but the rail becomes very sensitive to any side spin that is imparted on the golf ball. Directional accuracy must be very high and side spin must be very low. Indeed, if a rail 140 with an upper surface 143 of 0.5 inches were used and perfected in practice by the golfer, he/she would have a putting stroke variance of 0.5 percent and would be able to consistently hole a level putt of 18.2 feet. By increasing the putting precision requirement a golfer is forced to reduce stoke variance considerably in order to make a successful putt.

[0056] An alternative embodiment of a rail, designated broadly at 340, is shown in FIGS. 10A and 10B. The rail 340 has a flat surface 341 that extends the full width of the rail 340 and an opposed flat surface 342 that extends only partially the width of the rail 340 (in this embodiment, the surface 342 extends half of the width of the rail 340). Canted faces 343a, 343b extend between the edges of the surface 342 and the sides of the rail 340, such that in cross-section the rail 340 is an irregular hexagon. At one end the rail 340 has an inclined surface 344 that merges with the surface 341, and at the opposite the rail 340 has an inclined surface 345 that merges with the surface 342, such that the inclined surfaces 344, 345 are at opposite ends and on opposite sides of the rail 340.

[0057] The rail 340 can be substituted for either of the rails 40, 140 in the device 5 as a co-existent single rail. If a less precise putting device is desired, the rail 340 can be oriented in the channel 14 with the surface 341 facing upward (as in FIG. 10A), and the inclined surface 344 adjacent the near end 11 of the base 10. If a more precise putting device is desired, the rail 340 can be inverted such that the surface 342 faces upwardly and rotated such that the inclined surface 345 is adjacent the near end 11 of the base 10 (as in FIG. 10B). Thus, the rail 340 can provide the device 10 with different putting precision requirements with a single rail.

[0058] In alternative embodiments, the cross-section of the rail(s) may take many shapes for people of varying putting levels. For example, the upper surface of the rail could be convex or dome-shaped providing nearly a point contact with the golf ball for a very difficult challenge. Conversely, the upper surface of the rail could be a U-shaped channel, such that nearly everyone would have 100 percent success in putting the entire length of the rail. This would allow people learning the game of golf, such as children, to have a device that offers immediate rewards relative to the amount of skill level. For people who are not used to putting, simply standing in a putting position requires certain muscles that need to be developed, and having a device that virtually guarantees the making of a putt for a high percentage of putts) may provide some self-esteem to continue practicing. Additionally, rails may be covered with textured surfaces which simulate various speeds of natural golf putting greens. Although such surfaces would add variance to the rolling putt, it may be useful to one who has reduce stroke variance to an absolute minimum to see how various surfaces increase overall putting variance.

[0059] In some embodiments, the base and rail(s) are separate components; however, in an alternative embodiment both pieces may be made as one unitary device. For example, a solid piece of wood may be milled to include the insert as an integral part of the base. In this case there would be only one level of precision putting available. However, a golfer may prefer to have two separate integrated devicesone with a one inch insert milled into the base, and one with a one half inch insert integrated into the base, for example. This would prevent the inserts from being lost or accidentally broken if they are stored separately. The unified device is not limited to wood, as any plastic or metal insert can be milled into the main base to form a unitary device. In the case of plastic, the insert and base can be injection molded to form a unitary device.

[0060] Another embodiment of a putting practice device, designated broadly at 200, is illustrated in FIGS. 8A and 8B. The device 200 is, in essence, a combination of two devices 5 as described above with their bottom surfaces facing each other, with a rail 210 of one width on one side (e.g., one inch) and a rail 220 of a second, different width (e.g., inch) on the opposite side. The incline of each upper surface may be adjusted to provide a desired angle for the upper surfaces when either faces upwardly. This embodiment may typically be formed of plastic, as it can be easily formed on both sides, but in a complex machining operation, metal and perhaps wood could be used. Alternative versions of the device 200 includes two bases side-by-side sharing a common portion of the fence 70, with the bases having rails of different widths, or even two devices 200 joined side-by-side, such that four differently sized rails can be presented.

[0061] An additional feature of this invention is the capability to quantify putting precision. For example, an individual may wish to know whether he/she is improving at putting, or two people may wish to play a game between themselves to see who is the better putter. Consider the following example: two people putt with the same rail inserted in the device. Person A consistently gets 50% of his putts to roll the entire length of the insert to land in the hole and the other 50% of the time the ball falls off the insert within an inch or two of the hole. Person B,on the other hand, has 50% of the putts falling off in the middle of the insert and the other 50% falling off the insert within a few inches after making contact with the ball. Clearly person A is the better putter, because person A is able to consistently hit the putt farther up the insert than person B.

[0062] FIG. 9 is a top view of the device 5 with scorekeeping markings 35 on the upper surface 30 to indicate various lengths of puns that travel up the rail 40 before falling off the rail 40 and landing on the upper surface 30. The markings 35 may be used to quantify the length of each putt and can be used in conjunction with the rails 40, 140, 340 to provide a system to quantify the putt precision progress for a user. In an alternative embodiment, the markings may be printed on each rail.

[0063] An example of a method to quantify putt precision is shown in Table 1 below, and herein explained. In this example, a single person is using the method to quantify his expertise level at two different points in time.

[0064] Note that column 1 of the Table 1 is defined as a list of the rows to help explain and reference said table. Line 1 of Table 1 identifies each rail 40, 140 being used to help quantify putt precision is first listed. In this scenario one person is checking for improvement in putting using two time periods addressed as Test Date 1 and Test Data 2. Exemplary calculations will be described for Test Date 1. In Line 2 a numerical value for each rail is provided, a higher number being assigned to the narrower rail 140. Referring now to the first column for rail 40, in Table 1, Line 2 the value of 1 is recorded as the difficulty level. The user would then putt a golf ball up rail 40 three times and record the number of the area (based on the markings 35) in which each ball falls off of the rail 40 onto the upper surface 30. These values are shown in Lines 3, 4 and 5 and for rail 40 are values 4, 5, and 5 respectively. The values for all three putts are totaled in Line 6 and are shown in Table 1 to be 14, which is multiplied by the rail value from Line 2 to produce the putt-rail value registered in Line 7 as 14.

[0065] At this point the user replaces rail 40 with a narrower rail 140, and because rail 140 is narrower and more difficult it is assigned a relative value of 3. Again three puns are taken, and as shown in Table 1 the recorded values for the three putts for rail 140 are 3, 4 and 3 which total to 10 in Line 6. Therefore the total putt-rail value is 30 shown in Line 7.

[0066] Totals for the two inserts are then added and recorded as a total of 44 for Test Date 1.

[0067] Referring again to Table 1, the procedure is repeated for Test Date 2 and a final total of 54 is recorded. The user has improved his ability to make more precise puns by reducing his putting stroke variance (he is able to consistently hit the putt higher up each rail) leading to better accuracy and reduced side spin imparted on the putt.

[0068] The foregoing is illustrative of the present invention and is not to be construed as limiting thereof.
