Definitions
- the present invention relates to a new configuration for the dimples on a golf ball surface which improve the flight characteristics of the ball.
- U.S.G.A. United States Golf Association
- a golf ball may not have a weight in excess of 1.620 ounces or a diameter smaller than 1.680 inches.
- the initial velocity of balls conforming to U.S.G.A. regulations may not exceed 250 feet per second with a maximum tolerance of 2%.
- Initial velocity is measured on a standard machine kept by the U.S.G.A.
- a projection on a wheel rotating at a defined speed hits the test ball, and the length of time it takes the ball to traverse a set distance after impact is measured.
- Drag on a golf ball is also reduced by forming a plurality of dimples, often circular, in the outer surface of the ball.
- the dimples serve to reduce the pressure differential between the front and rear of the ball as it travels through the air.
- the Lu U.S. patent No. 5,503,398 discloses a golf ball having a plurality of dimples arranged on the spherical outer surface thereof, each of the dimples including a series of overlapping scales extending inwardly on an arcuate shaped sidewall surface of the dimple. The ball has improved directional control and increased lift and flight distance.
- the Oka U.S. patent No. 5,005,838 discloses a golf ball having a plurality of dimples in its outer surface. Each of the dimples includes a circular projection positioned in a bottom portion thereof. The projections are alleged to increase the coefficient of drag as the ball passes through the air, thereby decreasing the distance the ball will travel.
- the present invention was developed in order to provide a golf ball with reduced drag so that the ball will travel a greater distance than conventional golf balls having circular dimples.
- a golf ball having a spherical surface including a plurality of dimples arranged in the surface.
- the dimples are concavities in the ball surface at least some of which are modified so that part of the dimple surface is convex with respect to the dimple concave surface.
- these dimples have a raised contoured surface relative to the dimple bottom, with the contoured surface remaining below the surface of the ball.
- the contoured portion has a crescent configuration relative to the bottom surface.
- the contoured portion may comprise portions of different depths. The depth of a dimple at any point is the distance between the original undimpled ball surface and that point measured along a ball radius.
- the contoured portion includes a spaced pair of first portions having a first depth and a second portion arranged between the first portions and having a second depth different from the first depth.
- the contoured portion may also cover the entire bottom surface of the dimple.
- the contoured portion of at least one dimple is arranged adjacent to the contoured portion of an adjacent dimple.
- Fig. 1 is plan view of a golf ball including a plurality of contoured circular dimples according to the invention
- Figs. 2 and 3 are plan and sectional views, respectively, of a contoured dimple according to a first embodiment of the invention
- Figs. 4 and 5 are plan and sectional views, respectively, of a contoured dimple according to a second embodiment of the invention.
- Figs. 6 and 7 are plan and sectional views, respectively, of a contoured dimple according to a third embodiment of the invention.
- Figs. 8 and 9 are plan and sectional views, respectively, of a contoured dimple according to a fourth embodiment of the invention
- Figs. 9 and 10 are plan and sectional views, respectively, of a non-circular oval dimple according to a fifth embodiment of the invention.
- Figs. 1 1 and 12 are plan and sectional views of a triangular dimple according to a sixth embodiment of the invention.
- a golf ball 2 having a spherical surface which contains a plurality of circular dimples 4, the circle being defined where the dimple intersects with the surface of the ball.
- the dimples may all be of the same diameter, or different diameter dimples may be provided.
- each dimple has a bottom surface 6 defined by a radius of curvature r for the dimple. The radius further defines the depth d of each dimple.
- At least some of the dimples on the golf ball surface include a contoured portion 8 on the bottom surface.
- the contour which is analogous to a filled-in portion of the dimple— can take many different shapes, examples of which will be described in the embodiments of Figs. 2-9.
- the contoured portion has a depth less than the radius of curvature of the dimple.
- each contoured dimple includes a raised contoured portion relative to the dimple bottom, with the contoured portion being maintained below the surface of the golf ball.
- the ball diameter is not increased by the contoured portions.
- the ball 2 In order to comply with U.S.G.A. regulations, the ball 2 has an outer diameter of at least 1.680 inches.
- a first contoured dimple configuration is shown in Figs.
- the circular dimple has a crescent shaped contoured portion 8. This portion has a depth dl less than the depth d of the dimple 4. The depth of a dimple at any point is the distance between the original undimpled ball surface and that point measured along a ball radius.
- the width of the crescent is preferably in the vicinity of one-half the diameter of the dimple, but other widths may be provided as well.
- the dimple 104 in a golf ball 102 has a bottom surface 106 with a sinusoidal contoured portion 108.
- the sinusoidal contoured portion 108 has a depth d2 less than the depth d of the dimple 104.
- a third embodiment for a contoured circular dimple 204 in a golf ball 202 is shown in Figs. 6 and 7 wherein the contoured portion 208 in the dimple bottom surface 206 includes generally parallel portions 208a, 208b, 208c having different depths all of which are less than the total depth of the dimple. As shown particularly in Fig. 7, the portions 208a, 208b, and 208c define a stairstep configuration within the dimple.
- the contoured portion 308 covers the entire original bottom surface 306 of the dimple 304 in a golf ball 302. Moreover, the contoured portion comprises portions of different depths.
- the contoured portion includes a first portion 308a having a first depth, a second portion 308b having a second depth and a third portion 308c having a depth equal to that of the first portion as shown in Fig. 9.
- the second portion 308b is preferably arranged between the first and third portions and has a depth greater than the first depth.
- Figs. 10 and 11 the fifth embodiment of the invention wherein the dimple 404 in a golf ball 402 has an oval configuration.
- the contoured portion 408 of the dimple bottom surface 406 has a depth d4 less than the depth d of the dimple.
- a sixth embodiment of the invention is shown in Figs. 12 and 13 wherein the dimple 504 in a golf ball 502 has a triangular configuration, as does the contoured portion 508 of the dimple bottom surface 506.
- the contoured dimples C are arranged so that the contoured portions of adjacent dimples are also arranged adjacent one another.
- all of the contoured dimples can be paired with an adjacent dimple with the contoured portions adjacent. It will be appreciated that all of the dimples on the golf ball surface may be provided with contoured portions. Moreover, the dimples can be arranged on the golf ball surface in a random or geometric pattern. Any combination of contoured and non-contoured dimples may be provided.
- the contoured portion within the dimple significantly alters the air flow across the surface of the ball as it travels through the air when struck by a golf club.
- the altered air flow serves to decrease the drag on the ball, thereby increasing the distance that it will travel.
