Golf club heads with cavities and inserts and related methods

TECHNICAL FIELD

This disclosure relates generally to golf clubs, and relates more particularly to golf club heads with cavities and inserts.

BACKGROUND

Golf club manufacturers have designed golf club heads to accommodate the general preferences of its users as well as the individual user's golfing ability. Some golf club manufacturers also have designed golf club heads to accommodate the preferences of an individual user, such as an individual's preference for the golf club head's look and feel. Some golf club manufacturers also have designed golf club heads to accommodate other events associated with golf play. For example, some individuals dislike feeling vibrations in the golf club after hitting a golf ball. Thus, some golf club heads may be designed to lessen the undesirable vibrations during play, while maintaining elements to assist the individual with his/her game. Some golf club heads comprise an insert within a cavity of the golf club head in order to lessen the undesirable vibrations during play. However, the insert within the cavity can become dislodged within the cavity during impact. Therefore, an insert that can mechanically secure into the cavity to prevent dislodging is manufactured.

DESCRIPTION OF EXAMPLES OF EMBODIMENTS

Described herein is a golf club head that can comprise a central tuning port (CTP) weight positioned within a cavity of the golf club head. In many embodiments, the CTP weight comprises a first component and a second component, wherein the combination of the first and second component create a surface friction, or a retention lock/retention press fit to secure the CTP within the cavity of the golf club head. In other embodiments, the CTP weight comprises one component, which create a press fit to secure the CTP weight within the cavity of the golf club head. The CTP weight increase the weight of the golf club head to affect the center of gravity, thereby affecting the moment of inertia characteristics of the golf club head.

According to one embodiment, a golf club head having a body comprises a strikeface, a backface opposite the strikeface, a heel region, a toe region opposite the heel region, a sole and a rear portion. The golf club head further comprises a cavity positioned between the rear portion and the backface. The cavity comprises a width, a rear side wall having a recess, a face side wall opposite the rear side wall, and a bottom wall. The cavity is configured to receive an insert (or CTP weight). The insert comprises a first component (or body) having a width slightly less than the width of the cavity, and a second component (or retainer) having a width greater than the width of the cavity. The first component of the insert comprises a front surface, and a back surface. The front surface of the body comprises a slot extending toward the back surface of the first component, wherein a portion of the slot is separated into windows by portions of a material of the first component on the back surface of the body. The retainer of the insert is configured to be received by the first component through the slot on the front surface. The retainer comprises a first edge having tabs, and a second edge opposite the first edge having arms, wherein the arms can extend through the windows of the slot. When the insert is positioned within the cavity, the arms of the retainer are received within the recess on the rear side wall of the cavity and the tabs of the retainer are pressed against the face side wall of the cavity. The retainer of the insert create a press fit to secure the insert within the cavity. The retainer further forms a u-shaped curve creating a retention lock against the walls of the cavity to further secure the insert.

According to another embodiment of the golf club head, the cavity comprises a face side wall, a rear side wall opposite the face side wall, and a bottom side wall. The bottom side wall comprises a post extending into a portion of the cavity. The cavity is configured to receive an insert having a first component (or body), and a second component (or retainer). The first component can comprise a front surface, a back surface, a top surface and a bottom surface, wherein the front surface is adjacent to the face side wall when the insert is positioned within the cavity. The first component can comprise an insert cavity positioned on the front surface to receive the retainer, and the bottom surface to receive the post. The retainer is washer-like in shape and comprises a top portion, a bottom portion, a bore, and tabs extending from the bore, planar to the top and bottom portion. The bore of the retainer is configured to receive the post when positioned within the insert cavity of the first component. When the insert is positioned within the cavity, the post is received through the bore of the retainer and extends into a portion of the insert cavity of the first component. Further, the tabs of the retainer extend in an upward curve toward the top surface of the first component, such that an upward force is created from the tabs against the post. The upward force prevents the insert from dislodging from the cavity during impact.

According to another embodiment of the golf club head, the cavity of the golf club head comprises a divider, separating the cavity into a first pocket and a second pocket. The divider comprises an aperture. The cavity is configured to receive an insert having a first component and a second component, wherein the first component is positioned in the first pocket, and the second component is positioned in the second pocket of the cavity. The insert further comprises an insert aperture extending the first and second component, and is concentric with the aperture of the divider of the cavity. The aperture of the divider and the insert aperture is configured to receive a fastener to compress the first component and second component of the insert together with the divider. The compression creates a surface friction between the first and second component with the divider, thereby securing the insert within the cavity of the golf club head.

According to another embodiment of the golf club head, the cavity of the golf club head is configured to receive an insert. The insert comprises a surface, a front surface opposite the front surface, a heel region, a toe region opposite the heel region, a top surface, and a bottom surface opposite the top surface.

For example, the mass of the insert 1240 can be 0.02 grams, 0.50 grams, 1 gram, 5 grams, 10 grams, 15 grams, 20 grams, 25 grams, 30 grams, or 36 grams.

In some embodiments, the back portion 1252 and the front portion 1262 of the insert 1240 can comprise the same mass. In other embodiments, the back portion 1252 can comprise less mass than the front portion 1262 of the insert 1240. For example, the back portion 1252 can comprise a mass ranging from 0.02 gram to 0.80 gram, 0.080 gram to 4 grams, 4 grams to 8 grams, 8 grams to 12 grams, or 12 grams to 15 grams (e.g., 0.02 grams, 0.50 grams, 1 gram, 5 grams, 10 grams, or 15 grams), while the front portion 1262 can comprise a mass ranging from 7 grams to 32 grams, 7 grams to 15 grams, 15 grams to 18 grams, 18 grams, to 23 grams, 23 grams to 28 grams, 28 grams to 32 grams (e.g., 7 grams, 15 grams, 20 grams, 25 grams, 30 grams, or 32 grams). In other embodiments, the back portion 1252 can comprise more mass than the front portion 1262 of the insert 1240. For example, the front portion 1262 can comprise a mass ranging from 0.02 gram to 0.80 gram, 0.080 gram to 4 grams, 4 grams to 8 grams, 8 grams to 12 grams, or 12 grams to 15 grams (e.g., 0.02 grams, 0.50 grams, 1 gram, 5 grams, 10 grams, or 15 grams), while the back portion 1252 can comprise a mass ranging from 7 grams to 32 grams, 7 grams to 15 grams, 15 grams to 18 grams, 18 grams, to 23 grams, 23 grams to 28 grams, 28 grams to 32 grams (e.g., 7 grams, 15 grams, 20 grams, 25 grams, 30 grams, or 32 grams).

The insert aperture 1270 can receive a fastener 1274. The fastener 1274 can comprise a self-threaded screw, a co-molded thread, screw, rivets (solid head rivets or blind rivets) or any other type of fastener. The fastener 1274 can be one fastener 1274, two fasteners 1274, three fasteners 1274, four fasteners 1274, or five fasteners 1274. In many embodiments, the number of fastener 1274 corresponds with the number of insert aperture 1270. When the insert 1240 is positioned within the cavity 1216 of the golf club head 1200, the fastener 1274 is positioned through the insert aperture 1270 located on the back portion 1252 of the insert 1240, extends through the aperture 1228 of the divider 1222 and through the insert aperture 1270 in the front portion 1262 of the insert 1240.

When the fastener 1274 positioned within the insert aperture 1270, and the aperture 1228 of the divider 1222 helps secure and compress the insert 1240 against the divider 1222 of the cavity 1216. The compression of the insert 1240 against the divider 1222 creates a surface friction between the back inner surface 1256 of the back portion 1252 of the insert 1240 and the front inner surface 1266 of the front portion 1262 of the insert 1240 against the divider 1222. The combination of the fastener 1274 and surface friction prevents the insert 1240 from dislodging from the cavity 1216, thereby securing the insert 1240 within the cavity 1216.

In many embodiments, the insert 1240 can comprise a plastically deformable material. In some embodiments, the plastically deformable material of the insert 1240 can comprise metal, tungsten, aluminum, titanium, vanadium, chromium, cobalt, nickel, other metals, shim stock, steel, copper, metal alloy, plastic, or composite material.
