Embodiment Construction

[0043] As already stated, the invention relates to a head of a golf club of the "iron" type. In general, and as illustrated in FIGS. 1 and 2, such a head (1) comprises a hosel (2) intended to be connected to the shaft, and a striking face (3) which makes impact with the ball.

[0044] In its rear part, the head (1) comprises a cavity (4), the bottom (5) of which is behind the striking face (3). This cavity (4) is delimited laterally by a perimeter (6) consisting of various walls.

[0045] More specifically, this perimeter (6) comprises a lower wall (7) forming the sole of the head and the lower face (8) of which faces the ground at the moment of impact. The perimeter (6) also comprises two lateral walls (9, 10), the inner faces (11, 12) of which face toward the cavity (4). The perimeter (6) also comprises an upper wall (13). This upper wall (13) comprises several faces, namely:

[0046] an upper face (14) situated in the field of view of the golfer when he strikes the ball,

[0047] a lower fac...

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,...
