Abstract
A cast cup can include a forward portion of a golf club head, including a hosel, a face portion, and forward portions of a crown, sole, heel and toe. A rear ring can be formed separately from the cast cup and coupled to heel and toe portions of the cast cup to form a metallic club head body, such that the club head body defines a hollow interior region, a crown opening, and a sole opening. The cast cup and rear ring can be cast of titanium alloys. Composite crown and sole inserts can then be coupled to the crown opening and sole opening. The face portion of the cast cup can have a desirably complex geometry. The rear surface of the face portion of the cast cup can be modified before the rear ring is attached.
Claims26
A driver-type golf club head having a volume between 300 cm3 and 500 cm3, comprising:
- a first portion of the driver-type golf club head comprising a forward portion of the driver-type golf club head including a heel portion, a toe portion, a forward portion of a crown, and a forward portion of a sole, wherein the first portion comprises a first material having a first material density;
- a rear ring formed separately from the first portion and adhesively bonded to the first portion of the of the driver-type golf club head, wherein the rear ring connects to the first portion, such that a seam is defined between the rear ring and the first portion, to form a club head body defining a hollow interior region, a crown opening, and a sole opening, wherein the rear ring comprises a second material having a second material density;
- wherein the first portion at least partially encompasses a forward portion of the crown opening and a forward portion of the sole opening, and the rear ring at least partially encompasses a rearward portion of the crown opening and a rearward portion of the sole opening;
- the forward portion of the crown opening is defined by a forward crown opening recessed ledge of the first portion, and the forward portion of the sole opening is defined by a forward sole opening recessed ledge of the first portion;
- the rearward portion of the crown opening is defined by a rearward crown opening recessed ledge of the rear ring, and the rearward portion of the sole opening is defined by a rearward sole opening recessed ledge of the rear ring;
- a crown insert encloses the forward portion of the crown opening and the rearward portion of the crown opening, and is secured by adhesion to the forward crown opening recessed ledge and the rearward crown opening recessed ledge, and the crown insert is formed separately from the first portion and the rear ring;
- a rear weight secured to the rear ring;
- and
- a sole insert encloses the forward portion of the sole opening and the rearward portion of the sole opening, and is secured by adhesion to the forward sole opening recessed ledge and the rearward sole opening recessed ledge, and the sole insert is formed separately from the first portion, the rear ring, and the crown insert;
- wherein:
- the first portion of the driver-type golf club head further comprises toe and heel male projections and the rear ring further comprises toe and heel female notches, wherein the toe and heel male projections mate with corresponding ones of the toe and heel female notches to couple the first portion to the rear ring;
- or
- the first portion of the driver-type golf club head further comprises toe and heel female notches and the rear ring further comprises toe and heel male projections, wherein the toe and heel male projections mate with corresponding ones of the toe and heel female notches to couple the rear ring to the first portion;
- and
- wherein the rear ring forms a rear toe portion and a rear heel portion of the club head and defines a portion of an outermost perimeter of the golf club head.
