Set of golf clubs

Abstract

A set of golf clubs of the "iron" type, each club having a head, said head having a rear face, said rear face having a cavity delimited by walls, namely at least one lower wall forming the sole and an upper wall, said upper wall having several faces, namely a rear face, an upper face, a lower face facing the cavity and lateral faces, in which several clubs of said set have a head which has at least one recess made in the upper wall and opening onto a single face of said upper wall, away from the upper and lower faces, and wherein, the volume and / or the position inside the upper wall of said at least one recess varies from one club to another within said set, so that the position of the center of gravity of each head varies from one club to another.

Description

[0001] The invention relates to the field of golf. It relates more specifically to heads' of golf clubs of the "iron" type. It is aimed more specifically at irons which have a rear cavity, the geometry of which optimizes the distribution of mass while at the same time maintaining excellent striking qualities.PRIOR ART[0002] In general, golf clubs in which the head is made of cast or forged metal are known as "irons". Iron heads all have a flat striking face, the inclination of which varies with the number of the iron in the set. Thus, irons with low numbers, that is to say from 1 to 4, also known as "long irons" have a striking face which is not as inclined with respect to the vertical as irons known as "short irons", which have a high number in the set, that is to say 8, 9 and PW.[0003] One of the objectives in improving the tolerance of an iron consists in distributing the weight of the head at the perimeter, around the center of the striking face. The center of the striking face,...

AI Technical Summary

Benefits of technology

[0013] In other words, the upper wall delimiting the cavity is hollowed out to reduce the weight of this upper part. In consequence, the distribution of mass within the perimeter privileges the lower wall. By opening onto a single wall, the characteristic recesses do not weaken the perimeter.

Problems solved by technology

This solution increases the weight of the bottom part of the head, but has the disadvantage of stiffening the central zone of the striking face and therefore of reducing the "sweet spot" and therefore of providing results which are merely mediocre in terms of tolerance.

This solution has the disadvantage of weakening the perimeter through the presence of these slots.

In addition; the slots located on the upper face of the head are visible to the golfer, and are a visual annoyance to him.
