Abstract

A golf ball having a variable initial velocity associated with striking the golf ball with a driver having different head speeds is disclosed. The structure of the disclosed golf ball may cause the golf ball to experience an initial velocity comparable to premium golf balls currently on the market when hit with a driver head speed less than 100 mph. However, the same golf ball may experience an initial velocity higher than premium golf balls currently on the market when hit with a driver head speed higher than 125 mph. As a result, the disclosed golf ball may have different initial velocities associated with different head speeds.

Description

There is the multicore golf of high initial speed degree

The application requires the title submitted on August 23rd, 2011 for the U.S. Provisional Patent Application of " having the golf of high initial speed degree " (" Golf Ball Having High Initial Velocity ") number 61/526 according to 35U.S.C. § 119 (e), 594 priority, and this application is combined in to this by reference.

Checking after the following drawings and detailed explanation, to those skilled in the art, other system, method, the feature and advantage of the present invention can be or can become obvious.What intend is that all these type of other systems, method, feature and advantage in this explanation and general introduction comprise within the scope of the invention, and is subject to the protection of following claims.

Brief description of the drawings

With reference to the following drawings and description, the present invention may be better understood.Parts in accompanying drawing are not necessarily drawn in proportion, but emphasis is used for illustrating principle of the present invention.And in different views, similar reference number indicates corresponding part.

Fig. 1 has shown with a different types of golf at the long track comparison of hitting after bar hits with, the track of a golf prepared in accordance with the present invention;

Fig. 2 has shown the track of a golf prepared in accordance with the present invention after being hit by a wedge (pitching wedge);

Fig. 3 is according to the exemplary embodiment of Fig. 1 and 2 a golf.

Detailed description of the invention

In general, the present invention relates to a kind of golf with the variable initial velocity relevant from hit bar strike golf with the length of different bar head speed.The structure of the golf of this disclosure can make this golf when hit the strike of club head speed with the length that is less than 100mph, experience and the initial velocity that the high-quality golf on market is suitable at present.But identical golf can be to hit club head speed higher than the length of 125mph while hitting, experience is than at present at the high initial velocity of high-quality golf on the market.Therefore, the golf of this disclosure can have and the different initial velocity of different bar head velocity correlations.

Fig. 1 to 2 has shown an expressivity example embodiment of golf 100.In Fig. 1, amusement type linksman 142 uses a long bar 144 that hits to hit golf 100 and another kind of golf, and golf 182 leaves the ball seat 146 that is arranged in service area 148.As typical amusement type linksman, linksman 142 hits club head speed strike golf 100 and golf 182 to be less than the length of 100mph.Fig. 1 be presented at each golf by long hit bar 144 and hit after, the comparison between the track 150 of golf 100 and the track 180 of golf 182.Because having with hit club head speed with the length that is less than 100mph, each golf hit by long the similar initial velocity that bar 144 hits, therefore each golf has comparable path length.Because golf 100 is had similar initial velocity by long hitting after bar 144 hits hitting club head speed with the length that is less than 100mph, therefore approximately the same with track 180 extension longways of track 150.

In Fig. 2, professional linksman 152 uses length to hit bar 144 and hits golf 100 and another kind of golf, and golf 182 leaves the ball seat 146 that is arranged in service area 148.As typical professional linksman, linksman 152 hits club head speed strike golf 100 and golf 182 to be greater than the length of 125mph.Fig. 2 be presented at each golf by long hit bar 144 and hit after, the comparison between the track 160 of golf 100 and the track 162 of golf 182.Because golf 100 and golf 182 respectively have and are hit to be greater than the length of 125mph the different initial velocity that club head speed is hit by the long bar 144 that hits, therefore track 160 is longer than track 162.When being hit club head speed while hitting by the long bar 144 that hits to be greater than the length of 125mph, golf 100 has the initial velocity higher than the initial velocity of golf 182, and, and then golf 100 flies far than golf 182.

Table 3 has shown the test result that test ball is carried out to 6, and these test ball comprise golf prepared in accordance with the present invention and the existing golf that can buy on the market at present.Comprise example 1 according to the golf of this disclosure preparation, its details is presented in table 1.Materials A, B, C and D illustrate in greater detail to 11 with reference to table 8.Can comprise comparative example 1 to 4 at the existing golf of buying on the market at present, and the details of these comparative examples is presented at (wherein PBR is polybutadiene rubber) in table 2.Comprise initial velocity (IV) and take-off angle (launch angle) (LA) in table 3 to the result shown in 6.The uncertainty of the have ± 1mph of all results of IV.
