A golf club (40) having a club head (42) with a face component (60) and an aft-body (61) is disclosed herein. The face component (60) has a striking plate portion (72) and a return portion (74). The aft-body (61) is composed of a crown portion (62), a sole portion (64) and optionally a ribbon section (90). The face component (60) is composed of a metal material, and the aft-body (61) is composed of a non-metal material such as a composite material or a thermoplastic material. The striking plate portion (72) preferably has an aspect ratio less than 1.7. The striking plate portion (72) preferably has concentric regions of thickness with the thickness portion in the center (102). The club head (42) has a volume in the range of 300 cubic centimeters to 600 cubic centimeters, a weight in the range of 165 grams to 300 grams, and a striking plate portion (72) surface area in the range of 4.00 square inches to 7.50 square inches. The golf club head (42) has a coefficient of restitution greater than 0.81 under test such as the USGA test conditions specified pursuant to Rule 4-1e, Appendix II, of the Rules of Golf for 1998-1999.

As the club number increases so that the loft angle is larger, the center-of-gravity height HG of each head becomes larger, and the center-of-gravity depth ZG thereof becomes smaller. Each head is hollow, and a face portion becomes thicker in its lower portion. The back bottom thickness T is smaller in an iron shorter in club length.

A golf club having a hollow golf club head which is filled with a gas under pressure. The interior surface of the golf club head is coated with a solidified layer of plastic material. The pressurized gas permits the use of thinner face plates by compensating for forces generated when the face plate strikes a golf ball. The plastic layer is preferably applied through the process of rotational molding using a thermoplastic material.

A ball striking device, such as a golf club head, includes a head that includes a face having an outer surface located at a front of the head, a body connected to the face and extending rearward from the face, and a face mask connected to the outer surface of the face, the face mask having a first surface configured for forming at least a portion of a ball striking surface of the head configured for striking a ball, a second surface opposite the first surface and confronting the outer surface of the face, and a plurality of elongated slots extending completely through the face mask, from the first surface to the second surface. The slots combine with the outer surface of the face to form a plurality of face grooves on the ball striking surface.

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.

An iron-type golf club head is disclosed herein. The iron-type golf club head has multiple movable mass members which allow for the center of gravity to be moved at least 0.170 inch in a feel to toe direction and 0.070 inch in a crown to sole direction. Each of the movable mass members is preferably composed of a material having a density ranging from 12 g / cm3 and 14 g / cm3.

An improved line of golf clubs tailored to the golfer. The face wall firstly is designed so that the face wall modulus of elasticity increases from a low modulus for the low swing speed range to progressively higher modula for the higher swing speed ranges. Face modulus can be altered by a variety of techniques including face wall thinning, material selection and heat treatment or a combination thereof. In each of the swing speed range clubs, the face has a first modulus of elasticity determined by the face itself and after the face deflects to a predetermined value, the face modulus is significantly increased by a secondary wall parallel to and closely spaced behind the face wall.

A golf club incorporating an interchangeable shaft system includes a shaft, a shaft sleeve, a club head and a fastener. The shaft sleeve is coupled to an end of the shaft and is received in a hosel included in the club head. The fastener retains the shaft sleeve in the hosel. Hosel and shaft sleeve alignment features are provided that provide discreet orientations between the shaft and club head.

A golf club head is disclosed that includes a weight integral to a bridge member extending across a cavity back golf club head. The weight modifies a position of a center of gravity of the golf club head. The weight is independently movable in multiple directions to further vary the center of gravity of a golf club head.

A holster that may be donned in a first configuration for charging a pectorally implanted medical device on the patient's right side, a second configuration for charging a pectorally implanted medical device on the patient's left side, or a third configuration for use as a waist belt for charging a pectorally implanted medical device on either side of the patient.

A forged iron head for a golf club has a face for hitting a golf ball, a top and a sole extending to upper and lower parts of a rear side of the face, a heel and a toe disposed between the sole and the top, a cavity disposed in the rear side of the face and surrounded by the sole, the top, the heel and the toe and a hosel coupled with a shaft extending from a first side of the face and having a handle part to be gripped by a player. The head comprises a hollow part with an opening formed from the sole toward a first side of the cavity, and a sole cover which closes the opening. The formation of the hollow part lowers the centroid of the iron head, thereby improving flight distances and direction of a golf ball.

Apparatuses, methods and systems related to an improved golf data collecting and golf club notification system. The system reminds golfers when a club has been mistakenly left behind on the golf course and notifies the golfer when a golf club or clubs are in or out of the golf bag. The system can notify a golfer if a club or golf bag has been removed without authorization. In one preferred embodiment an apparatus that attaches to a golf club includes dual light sensors—one light sensor configured as a switch and one light sensor configured as a light meter. Algorithms make use of the light sensor data to determine whether a golf club is in or out of a golf bag.
