Abstract

A ball striking device, such as a golf club, includes a head with a face having an outer surface configured for striking a ball, a body connected to the face, an elongated, inwardly recessed channel located on the body and extending across a portion of the body, and an insert mounted within the channel. The insert includes a resiliently deflectable base member that engages the channel to retain the insert within the channel and a rigid outer member connected to the base member and forming at least a portion of the outer surface of the insert, where the outer member is made from a different material than the base member. Additionally, the insert has an outer surface that is substantially flush with at least one immediately adjacent surface of the body.

Claims

a channel located on the body and extending across a portion of the body, the channel being inwardly recessed from an exterior surface of the body and having a trough at a maximum depth of the channel, wherein the channel has a width defined in a front-to-rear direction, and wherein the width of the channel is greatest proximate the exterior surface of the body and decreases to a minimum width at the trough; and

an insert mounted within the channel and engaging the channel to retain the insert within the channel, wherein the insert has a width defined in the front-to-rear direction, and wherein the width of the insert is greatest at an outer surface of the insert and decreases to a minimum width at an inner surface of the insert engaging the trough,

wherein the body has a thin-wall construction, and the body and the face combine to define an internal cavity, and wherein the channel creates a raised portion on an interior surface of the body, and

wherein the channel includes a slot located at the trough and extending into the internal cavity, and wherein a portion of the insert is received within the slot and is exposed to the internal cavity.

2. The golf club head of claim 1, wherein the channel is elongated in a heel-to-toe direction, such that the trough of the channel extends in the heel-to-toe direction.

3. The golf club head of claim 1, wherein the width of the channel decreases constantly from the exterior surface of the body to the trough, and wherein the width of the insert decreases constantly from the outer surface of the insert to the inner surface of the insert.

4. The golf club head of claim 1, wherein the insert is at least partially formed of a flexible polymer material.

5. The golf club head of claim 1, wherein the insert comprises a base member formed of a flexible polymer material and an outer member formed of a second material having greater rigidity than the flexible polymer material, the outer member forming at least a portion of the outer surface of the insert.

6. The golf club head of claim 1, wherein the channel has a curvilinear shape in a cross-section taken in the front-to-rear direction, such that the channel has side walls that curve inwardly and toward each other as the width of the channel decreases from the exterior surface to the minimum width at the trough.

7. The golf club head of claim 6, wherein the insert has a curvilinear shape in a cross-section taken in the front-to-rear direction, such that the insert has sides that curve inwardly and toward each other as the width of the insert decreases from the outer surface to the minimum width at the inner surface.

8. The golf club head of claim 1, wherein the outer surface of the insert is substantially flush with the exterior surface of the body.

9. The golf club head of claim 1, wherein the channel extends across a portion of the sole of the body and is located adjacent a bottom peripheral edge of the face.

10. A golf club head comprising:

a face having a ball striking surface configured for striking a ball;

a body connected to the face and extending rearwardly from the face, wherein the body has a crown, a sole, a heel, a toe, and a rear opposite the face;

a channel located on the body and extending across a portion of the body, the channel having a front edge and a rear edge located at an exterior surface of the body, the channel further having front and rear side walls extending inwardly from the front and rear edges to a trough, wherein the channel has a width defined in a front-to-rear direction, and wherein the channel has a maximum width defined between the front and rear edges, and wherein the front and rear side walls extend toward each other such that the width of the channel decreases to a minimum width at the trough; and

an insert mounted within the channel and engaging the channel to retain the insert within the channel, the insert having an outer surface with a front edge and a rear edge, wherein the insert has a width defined in the front-to-rear direction, and wherein a maximum width of the insert is defined between the front edge and the rear edge at the outer surface of the insert and decreases to a minimum width at an inner surface of the insert engaging the trough,

wherein the body has a thin-wall construction, and the body and the face combine to define an internal cavity, and wherein the front and rear side walls extend into the internal cavity, such that the channel creates a raised portion on an interior surface of the body, and

wherein the channel includes a slot located at the trough and extending into the internal cavity, and wherein a portion of the insert is received within the slot and is exposed to the internal cavity.

11. The golf club head of claim 10, wherein the channel is elongated such that the front and rear edges of the channel extend in heel-to-toe directions.

12. The golf club head of claim 10, wherein the front and rear side walls converge constantly toward each other, such that the width of the channel decreases constantly from the front and rear edges to the trough, and wherein the width of the insert decreases constantly from the outer surface to the inner surface of the insert.

13. The golf club head of claim 10, wherein the insert is at least partially formed of a flexible polymer material.

14. The golf club head of claim 10, wherein the insert comprises a base member formed of a flexible polymer material and an outer member formed of a second material having greater rigidity than the flexible polymer material, the outer member forming at least a portion of the outer surface of the insert.

15. The golf club head of claim 10, wherein the channel has a curvilinear shape in a cross-section taken in the front-to-rear direction, such that the front and rear side walls curve inwardly and toward each other as the width of the channel decreases from the front and rear edges to the minimum width at the trough.

16. The golf club head of claim 15, wherein the insert has a curvilinear shape in a cross-section taken in the front-to-rear direction, such that the insert has sides that curve inwardly and toward each other as the width of the insert decreases from the outer surface to the minimum width at the inner surface.
