Golf club head

Abstract

A wood-type golf club head has a hollow shell structure having a head length L (mm), a head-depth W (mm) and a sweet spot height H (mm) which satisfy: 0.80≦W/L≦1.0 and H≦76×(W/L)−31. The head length L is the distance between the clubshaft axis CL and a point T farthest from the clubshaft axis CL. The head depth W is the distance between a plane FP tangent to the sweet spot SS and a point B farthest from the plane FP.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a golf club head, more particularly to a wood-type golf club head having a hollow structure configured to increase the carry distance.[0002]Wood-type hollow golf club heads having various shapes have been proposed.[0003]With respect to the position of the center of gravity of the head, there is a tendency that, when the size of the golf club head in the back-and-forth direction is increased, the distance of the center of gravity from the club face is also increased. Since the club face is usually provided with a loft angle larger than 0 degree, the sweet spot height increases with the increase in the distance of the center of gravity. This will increase the likelihood that the golf ball hits a lower part of the club face under the sweet spot, and the backspin is increased due to the gear effect. As a result, the ball flight tends to become so called “ballooning” or “rising” trajectory due to too much backspin and a re...

Benefits of technology

[0005]It is therefore, an object of the present invention to provide a golf club head in which, by optimizing the head shape in relation to the position of the sweat

Problems solved by technology

Therefor, there is a tendency that even at the time of impact the head can not return to the right address position where the club face is at right angle to the target line (trajectory) of the ball, and so called “ball gripping” or “ball holding” on the club
