Low-weight two piece golf balls

Abstract

The present invention is directed to a golf ball with a core and a cover layer surrounding the core. The golf ball preferably has a weight between about 44.5 grams and about 45 grams, a diameter of at least about 1.68 inches, and a deflection of about 3.0 mm to about 4.0 mm at 100 kg. Additionally, the golf ball preferably has a coefficient of restitution of at least about 0.82 at a club head speed of 100 ft / sec. The golf ball includes aerodynamics to provide an optimal trajectory and overall distance for the low weight ball. Thus, a low weight golf ball is provided delivering improved distance with superior feel. This golf ball is specifically designed to optimize its play characteristics for low swing speed players.

Description

TECHNICAL FIELD OF INVENTION [0001] The present invention generally relates to golf balls, and more particularly to a low weight two piece golf ball for golfers with a low club head speed. BACKGROUND OF THE INVENTION [0002] The flight of a golf ball is determined by many factors, but only three factors are typically controlled by the golfer. By impacting the ball with a golf club, the golfer controls the speed, the launch angle and the spin rate of the golf ball. The launch angle sets the initial trajectory of the golf ball's flight. The speed and spin of the ball give the ball lift which will define the ball's overall flight path along with the weight and drag of the golf ball. Where the ball stops after being struck by a golf club also depends greatly on the weather and the landing surface the ball contacts. [0003] Many golfers have what is termed a “low swing speed.” This means that the club head speed at impact is relatively slow when compared to a professional golfer's. Typical...

AI Technical Summary

Benefits of technology

The present invention is directed to a golf ball with a specific weight, diameter, and coefficient of restitution. The golf ball has a core and a cover layer with a specific hardness. The cover layer has a plurality of dimples that provide optimal trajectory and distance. The dimples have a specific size and are arranged in a pattern to achieve the desired performance. The golf ball has a deflection at 100 kg of about 3.0 mm to about 4.0 mm and a coefficient of restitution of about 0.82 to about 0.87 at a club head speed of 100 ft / sec. The invention also includes a golf ball with a weight between about 44.5 grams and about 45 grams, a deflection at 100 kg of about 3.0 mm to about 4.0 mm, a diameter of at least 1.68 inches, and a coefficient of restitution of about 0.82 to about 0.87 at a club head speed of 100 ft / sec.

Problems solved by technology

Many golfers have what is termed a “low swing speed.” This means that the club head speed at impact is relatively slow when compared to a professional golfer's.

Consequently, his or her ball does not fly very far because of the lack of speed and lift.

However, these balls tend to have a hard feel and are difficult to control around the greens.

Additionally, these golf balls can have insufficient mass to provide good distance at the target audience.

Lightweight golf balls typically have a dimple package tuned for a standard weight golf ball, which results in a ball that flies too high and short.
