1. Field of the Invention
The present invention relates to an adjusting block for a golf club head. In particular, the present invention relates to an adjusting block for adjusting the center of gravity and moment of inertia of a golf club head.
2. Description of Related Art
U.S. Patent Publication No. 2004/0214657 A1 discloses a golf club head comprises a main body, a striking plate, and a weight. The main body includes a ring frame, and the striking plate is combined with a front side of the main body. The striking plate includes a front surface for striking a golf ball and a rear surface for combining with the weight. The main body, the striking plate, and the weight are made of metal.
The density of the weight is greater than those of the main body and the striking plate such that the weight has a relatively smaller volume. In manufacture, a smaller weight is adopted and thus could not completely fill the volume of a specific space in the body. A space must be preserved in a particular location in the main body for the weight, leading to difficult adjustment in the center of gravity and moment of inertia. Further, the size of the main body is reduced if the size of the weight, leading to a reduction in the area of the striking plate. The striking effect is adversely affected accordingly.
In brief, there is a need in an improved arrangement for the main body and the weight to allow flexible adjustment of the center of gravity and moment of inertia of the golf club head.
OBJECTS OF THE INVENTIONAn object of the present invention is to provide an adjusting block that allows flexible adjustment of the center of gravity of a golf club head.
Anther object of the present invention is to provide an adjusting block that allows flexible adjustment of the moment of inertia of a golf club head.
A further object of the present invention is to provide an adjusting block that can be easily assembled to or detached from a golf club head.
Still another object of the present invention is to provide a golf club head that provides a space for receiving a weight as well as other head components.
SUMMARY OF THE INVENTIONIn accordance with a first aspect of the present invention, a golf club head comprises a body having a cutaway recession and an adjusting block mounted in the cutaway recession. The body includes a striking face for striking a golf ball. The adjusting block includes a chamber in which at least one accessory member is mounted.
Preferably, a wall delimiting the cutaway recession includes an engaging portion. Preferably, the adjusting block includes an engaging section engaged with the engaging portion when the adjusting block is mounted in the cutaway recession of the body. Preferably, the engaging portion includes at least one guiding face for guiding the engaging section of the adjusting block into the engaging portion.
The body may further include an upper reinforcing wall delimiting the cutaway recession. The body may further include a lower reinforcing wall delimiting the cutaway recession.
In an embodiment of the invention, the cutaway recession tapers outward for improving engaging strength of the adjusting block in the cutaway recession. In another embodiment of the invention, the cutaway recession tapers inward for allowing easy mounting of the adjusting block.
In an embodiment of the invention, a bottom wall delimiting the cutaway recession includes a recess, and the adjusting block includes a protrusion engaged in the recess.
In another embodiment of the invention, a bottom wall delimiting the cutaway recession includes a recess, and a vibration-absorbing member is mounted in the recess and sandwiched between the adjusting block and a bottom wall delimiting the recess.
In a further embodiment of the invention, at lease one of two sidewalls delimiting the chamber of the adjusting block protrudes into the chamber. At least one of two sidewalls delimiting the cutaway recession presses against the at least one of the sidewalls delimiting the chamber of the adjusting block, slightly expanding the adjusting block and reliably fixing the adjusting block in the cutaway recession.
Preferably, the accessory member includes a section with a width greater than that of the chamber for slightly expanding the adjusting block and reliably fixing the adjusting block in the cutaway recession.
In still another embodiment of the invention, a casing covers the adjusting block and includes at least one notch allowing expansion of the adjusting block. The casing includes a slot aligned with the chamber of the adjusting block, allowing insertion of the accessory member into the chamber of the adjusting block.
In yet another embodiment of the invention, the cutaway recession is defined in an upper portion of the body.
In still another embodiment of the invention, the cutaway recession is delimited by an upper reinforcing wall and a lower reinforcing wall to form a compartment.
In accordance with a second aspect of the present invention, a golf club head comprises a body including a cutaway recession, an adjusting block mounted in the cutaway recession, and a casing covering the adjusting block. The adjusting block includes a chamber in which at least one accessory member is mounted.
In accordance with a third aspect of the present invention, a golf club head comprises a body including a compartment, an adjusting block mounted in the compartment, and a casing covering the adjusting block. The adjusting block includes a chamber in which at least one accessory member is mounted.

In the illustrated embodiment, the adjusting block 2 as a whole is a block made of elastomeric material selected from a group consisting of resins (such as epoxy resin), high molecular polymers, rubber, thermoplastic elastomers, polyurethane and combinations thereof. The adjusting block 2 includes a chamber 20 for receiving at least one accessory member 3. In the illustrated embodiment, the adjusting block 2 includes an engaging section 21 on each of two lateral walls thereof. Each engaging section 21 includes at least one guiding face 211 to allow easy mounting/removal of the adjusting block 2 into/from the cutaway recession 11 of the body 1. In the illustrated embodiment, each engaging section 21 is a protrusion having an inner guiding face 211 and an outer guiding face 211.
The accessory member 3 may be a weight member, damping member, or an ornamental cover for a golf club. Preferably, the accessory member 3 includes an expanding section for pressing against an inner periphery delimiting the chamber 20 of the block 2, thereby resiliently expanding and deforming the block 2. The accessory member 3 includes a first width W1 and a second width W2. In the illustrated embodiment, the inner side of the accessory member 3 has the second width W2 that is equal to a width of the chamber 2, and the outer side of the accessory member 3 has the first width W1 that is greater than the second width W2. Thus, when the accessory member 3 is inserted into the chamber 20 of the engaging block 2, the outer perimeter of the adjusting block 2 deforms and expands outward. On the other hand, if the accessory member 3 is removed from the chamber 20 of the engaging block 2, the outer perimeter of the engaging block 2 resumes its original shape.

As illustrated in
Preferably, the material for forming the vibration-absorbing member is selected from a group consisting of aluminum alloy, magnesium alloy, titanium alloy, copper alloy, stainless steel, tungsten alloy, nickel-based alloy, resins (such as epoxy resin), high molecular polymers, rubber, thermoplastic elastomers, polyurethane and combinations thereof.
Further, the adjusting block 2 is covered by a substantially U-shaped casing 23 having a slot 231 in an intermediate section thereof. The slot 231 of the casing 23 is aligned with the chamber 20 of the adjusting block 2, allowing insertion of the accessory member 3 into the chamber 20 via the slot 231. The U-shaped casing 23 further includes two openings or notches 231 respectively in two sides thereof. The engaging sections 21 of the adjusting block 2 are respectively located in the notches 231, allowing lateral expansion of the adjusting block 2, whereas expansion of the adjusting block 2 in the vertical direction is restrained by the casing 23.
While the principles of this invention have been disclosed in connection with specific embodiments, it should be understood by those skilled in the art that these descriptions are not intended to limit the scope of the invention, and that any modification and variation without departing the spirit of the invention is intended to be covered by the scope of this invention defined only by the appended claims.
