Technical field

The utility model relates to golf, particularly relates to one and has unique golf of filling (packed) patterns of indentations.More especially, the utility model relates to a kind of by producing irregular territory according to polyhedron, particularly dipyramid, filling irregular territory with indenture and this territory being embedded in golf surface to come up to arrange the method for indenture on golf.

Background technology

In history, the patterns of indentations for golf has had multiple geometry, pattern and structure.Mainly, pattern is arranged to the manipulation characteristic providing expectation according to sportsman's characteristic of specific ball structure, material properties and the initial percussion angle and rotation status that affect ball.Therefore, the exploitation of pattern is used to the secondary design procedure realizing suitable aerodynamic quality, the flight characteristics controlling ball thus and performance.

The air force educational level awing produced by ball is caused by its speed and rotation.These power can be represented as lifting force and drag.Lifting force perpendicular to flight direction, and be rotate ball above and below air velocity difference cause.This phenomenon is summarized as Magnus Effect, and Magnus so described after studying the air force educational level on spinning ball and cylinder in 1853, and is described by Bernoulli equation (simplification of first law of thermodynamics).Bernoulli equation makes pressure and velocity correlation, wherein square being inversely proportional to of pressure and speed.The power be directed upwards towards that the speed difference caused due to the very fast motive air at top and the slower motive air of bottom causes the lower air pressure at top and acts on ball.

The direction of towing is contrary with heading and perpendicular to lifting force.Drag on ball is summarized as parasitic drag, and it comprises pressure towing and viscosity or friction subsurface and pulls.Ball is bluff body, and it has non-effective aerodynamic shape.Therefore, very large pressure differential is caused in the acceleration flow field around ball, and its mesohigh is before ball, and low pressure is after ball.Ball area of low pressure below is also known as tail (wake).Minimum in order to make pressure pull, indenture provides as flow field energy supply and postpones the separation of stream or reduce the measure in the tail region after ball.Friction subsurface is the viscous effect on the ball surface in boundary layer.

This area is sought many effort by indenture interference and additive method and is made the aerodynamic efficiency of golf maximum, although they are strictly controlled by golf governing body of country (United States Golf Association (USGA)).A requirement of USGA is that golf club has air force symmetry.Air force symmetry allows ball with the flight of very little variable quantity, and no matter how golf is placed on ball seat or ground.Preferably, indenture covers the maximized surface area of golf, and does not adversely affect the air force symmetry of golf.

In the symmetric trial of improvement air force, many patterns of indentations are based on geometry.These shapes comprise circle, hexagon, triangle etc.Other patterns of indentations is generally based on five kinds of Platonic solids, and it comprises icosahedron, dodecahedron, octahedron, cube or tetrahedron.Other patterns of indentations based on 13 kinds of Archimedes's entities, such as little icosidodecahedron, tiltedly icosidodecahedron, little oblique pair of cuboctahedron, short cube, short dodecahedron or cut icosahedron.In addition, other patterns of indentations is based on hexagon dipyramid.Because the quantity of symmetrical physical plane system is restricted, be difficult to design new symmetrical pattern.In addition, the patterns of indentations based on some shapes of these geometries causes not best surface coverage and other disadvantageous indenture to arrange.Therefore, the indenture performance usually attempting manipulating such as quantity, shape, size, volume and layout has the golf of the aerodynamic quality of improvement with formation.

The U.S. Patent No. 5562552 of Thurman discloses a kind of golf, it has icosahedron patterns of indentations, wherein icosahedral each gore by three straight lines separately, this straight line divides the bight in this face respectively equally, to form three gores being used for each icosahedron face, wherein indenture is consistently arranged on icosahedron face.

The U.S. Patent No. 5046742 of Mackey discloses a kind of golf, and it has the indenture be filled in the polyhedron comprising hexagon and pentagonal 32, and it is identical that the indenture wherein in each hexagon and pentagon is filled.

The open one of U.S. Patent No. 4998733 of Lee forms golf by ten " spherical " is hexagonal, hexagon is divided into six equilateral triangles respectively, wherein each triangle is split by the bisector extended between vertex of a triangle and the mid point of the side relative with this summit, and bisector is directed, to realize the symmetry improved.

The U.S. Patent No. 6682442 of Winfield discloses the polygonal use as the packing elements for indenture, patterns of indentations is introduced in predictable change.Polygon extends to parting line from the pole of ball.Any indenture of not filling other from the space of polygon filling indenture.
