Description

Counterweight component and golf club head with the counterweight component

The present invention relates to a component and a golf tool with the component, in particular to a weight component and a golf club head with the weight component.

Refer to Figures 1 and 2, in order to conform to the user’s hitting habits, a general golf club head often adjusts the position of the center of gravity by setting weights to produce a satisfactory hitting feel. Common weights are shown in the figure In the design of 1, the counterweight 11 is designed as a bolt and locked on the ball head body 12 so that the user can lock on the hole 121 when needed. However, the opening position of the hole 121 is fixed, so the counterweight Block 11 cannot freely select the setting position, and lacks the degree of freedom of adjustment.

The other is as shown in Figure 2, a sliding groove 132 with a retaining wall 131 is opened on the ball head body 13, and the counterweight 14 is designed as a two-piece design that can be locked with each other. 14 clamps the blocking walls 131 up and down and locks each other, thereby clamping and fixing the counterweights 14 on the ball head body 13, and the user can loosen the counterweights 14 and fix the counterweights 14 according to their needs. The counterweight 14 moves to a specific position along the chute 132, so that the position of the counterweight can be adjusted freely, so that the golf club head can be more comfortable during the swing. However, due to structural strength and other factors, the protruding area of the blocking wall 131 is limited, so the contact area between the counterweight 14 and the blocking wall 131 is small, which also causes the weight of the counterweights 14 to be limited and reduce The universal use of the counterweight.

Therefore, the purpose of the present invention is to provide a counterweight assembly that can increase the load-bearing weight.

Therefore, the counterweight assembly of the present invention includes a first counterweight defining a setting slot opened along a pushing direction, two fixing members located in the setting slot and abutting the first counterweight, and an edge The second counterweight is located between the fixing parts in the pushing direction, and a locking part that passes through the first counterweight and is locked to the second counterweight. Each fixing member has a flat pushing surface exposed outside the setting groove along the pushing direction, and an inclined pushing surface connected to the flat pushing surface, and the second counterweight has at least one facing toward the first A counterweight is in contact with the inclined bearing surfaces of the inclined surfaces. When the locking member is locked, the second counterweight will press against the first counterweight so that the at least one inclined bearing surface The inclined pushing surfaces are pushed, and the flat pushing surfaces are pushed outward along the pushing direction.

Another object of the present invention is to provide a golf club head with the weight assembly.

Therefore, the golf club head of the present invention defines a thrust direction and an extension direction perpendicular to each other, and includes a head body and a weight component detachably fixed on the head body. The ball head body has a bottom wall surface and two side wall surfaces spaced apart along the pushing direction and connected to the bottom wall surface. The bottom wall surface and the side wall surfaces cooperate to define a sliding groove extending along the extending direction. The counterweight component is clamped in the chute, and includes a first counterweight defining a setting slot opened along the pushing direction, and two located in the setting slot and contacting the first counterweight A fixing piece, a second counterweight located between the fixing pieces along the pushing direction, and a locking piece that penetrates the first counterweight and is locked on the second counterweight, each The fixing member has a flat pushing surface exposed out of the setting groove along the pushing direction and pushing against the corresponding side wall surface, and an inclined pushing surface connected to the flat pushing surface and in an inclined shape. The second counterweight has At least one inclined bearing surface facing the first counterweight and in contact with the inclined pushing surfaces, when the locking member is locked, the second counterweight will press the first counterweight to make the At least one inclined bearing surface pushes the inclined pushing surfaces, so that the horizontal pushing surfaces respectively urge the side wall surfaces outward along the pushing direction.

The effect of the present invention is that the counterweight component can move in the chute along the extension direction to adjust the position, and by tightening the locking member, the horizontal pushing surfaces can be forced outward against the side wall surfaces, thereby The counterweight component is clamped on the ball head body. Since the flat pushing surfaces have a larger contact area with the side wall surfaces, a larger frictional force can be generated and the fixing effect can be increased. Therefore, the first configuration The weight of the weight and the second weight can be relatively increased, providing a higher degree of freedom and personalized weight selection.

Referring to FIGS. 3, 4, and 5, an embodiment of the golf club head of the present invention includes a head body 2 and a weight assembly 3 detachably disposed on the head body 2. An extension direction A, an pushing direction B perpendicular to the extension direction A, and a depth direction C perpendicular to the extension direction A and the pushing direction B are defined. The ball head body 2 has a bottom wall surface 21 and two side wall surfaces 22 spaced apart along the pushing direction B and connected to the bottom wall surface 21. The bottom wall surface 21 and the side wall surfaces 22 cooperate to define a chute 23 extending along the extension direction A. In this embodiment, the extension direction A extends along a curve, but it is not limited thereto. The angle between the bottom wall surface 21 and the side wall surfaces 22 is less than ninety degrees, so that the width of the chute 23 presents a push-out state with a wide inside and a narrow outside.

The counterweight assembly 3 is located in the chute 23, and the width of the chute 23 is wide inside and narrow at the outside, so that the counterweight assembly 3 is not easy to move or loosen along the depth direction C to achieve a better limit effect. The counterweight assembly 3 includes a first counterweight 31 defining a slot 311 opened along the pushing direction B, and two fixing members 32 located in the slot 311 and abutting the first counterweight 31 , A second counterweight 33 located between the fixing members 32 along the pushing direction B, and a locking member that penetrates the first counterweight 31 and is locked to the second counterweight 33 34. Each fixing member 32 includes an outer expansion portion 321 and a limiting portion 322 extending from the outer expansion portion 321 toward the other fixing member 32 along the pushing direction B. The limiting portions 322 of the fixing members 32 are located on opposite sides of the locking member 34 along the extending direction A, and the limiting portions 322 define a through hole 323 for the locking member 34 to pass through. The expanded portion 321 has a flat pushing surface 324 exposed outside the setting groove 311 along the pushing direction B and pushing against the corresponding side wall surface 22, and a flat pushing surface 324 connected to the flat pushing surface 324 and inclined and facing the bottom The inclined surface 325 of the wall 21. The second counterweight 33 has two inclined bearing surfaces 331 arranged at intervals along the pushing direction B and facing the first counterweight 31, and respectively contacting the inclined surfaces 325.

The method of use of this embodiment is as follows: the counterweight assembly 3 is placed in the chute 23, and then moved to a suitable counterweight position along the extension direction A, and finally the locking member 34 is locked, which will cause the second The counterweight 33 is pressed toward the first counterweight 31, and the fixing members 32 are clamped along the depth direction C, so that the inclined bearing surfaces 331 push the inclined pushing surfaces 325 respectively, so that each inclined The pushing surface 325 is relatively inclined and slid down along the corresponding inclined bearing surface 331, so that the expanded portions 321 move outwards, and are pressed against the side wall surfaces 22 through the flat pushing surfaces 324, so that the fitting The heavy component 3 is clamped in the chute 23 to achieve positioning. Since the flat pushing surfaces 324 and the side wall surfaces 22 have a larger contact area, sufficient friction can be generated to achieve a better fixing effect, so as to correspond to the heavier first weight 31 and The second counterweight 33 enhances the degree of freedom of the counterweight.

In summary, the present invention can increase the fixing force through the large-area contact between the flat pushing surfaces 324 and the side wall surfaces 22, and the first and second weights 31, 33 with heavier weight can be used. The degree of freedom is relatively high, and the shape of the chute 23 is narrow and wide inside, which can prevent the counterweight assembly 3 from being displaced and loosened outwards, so it can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
