Golf club head and method for making it
First Claim
1. A golf club head comprising:
- a hollow main body having a sole, a crown, a heel, a toe, a ball-striking face, and a rear wall, wherein the rear wall defines a rear wall cavity, and wherein the hollow main body defines a central axis along which the head is intended to move when being used to strike a golf ball; and
a weight cartridge including a polymeric housing and a weight, wherein the polymeric housing defines an elongated cavity sized and configured to conformably receive the weight;
wherein the rear wall cavity is substantially aligned with the central axis and is sized and configured to conformably and slidably receive the polymeric housing of the weight cartridge, along an axis substantially aligned with the central axis;
wherein the rear wall cavity includes an upper wall, a lower wall, a heelward wall, and a toeward wall, each extending into the hollow main body;
and wherein the rear wall cavity is configured to retain the weight cartridge in an installation position without the need for a screw attachment.

Abstract
An improved golf club head is disclosed, in which a desired weight for the head is precisely controlled by installing into a cavity formed in the rear wall of the club head'"'"'s hollow main body a selected weight cartridge from a group of such cartridges having identical sizes but a range of weights. The selected weight cartridge is installed simply by sliding it into the rear wall cavity, where it is retained by a snap fit, and/or by an interference fit, and/or by a suitable bonding material, without the need for a screw attachment. This greatly simplifies the golf club head'"'"'s manufacture, thus reducing its cost. The invention is applicable to golf club heads of all kinds, including metal woods, irons and putters.

20. A method for making a golf club head having a desired weight, comprising:
-
forming a hollow main body having a sole, a crown, a heel, a toe, a ball-striking face, and a rear wall, wherein the rear wall defines a rear wall cavity having an upper wall, a lower wall, a heel-ward wall, and a toe-ward wall, all extending into the hollow main body, and wherein the hollow main body defines a central axis along which the head is intended to move when being used to strike a golf ball;
providing a plurality of weight cartridges, each comprising a polymeric housing and a weight, wherein the polymeric housing defines an elongated cavity sized and configured to conformably receive the weight;
wherein the plurality of weight cartridges all have substantially the same size and shape and each are configured to conformably fit into the rear wall cavity, and wherein the plurality of weight cartridges, together, have a range of weights;
selecting a particular one of the plurality of weight cartridges having a weight that will combine with the weight of the hollow main body to provide a desired total weight; and
installing the selected weight cartridge in its installation position in the rear wall cavity by sliding the cartridge into the cavity from outside the hollow main body, along an axis substantially aligned with the central axis, where it is retained without the need for a screw attachment, thereby producing a golf club head having the desired weight. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)
