Description

Golf putter head with removable weight {Golf putter head}

The present invention relates to a golf putter head having a removable weight, and more specifically, to a golf putter head having a removable weight, in which a shaft fixing groove is formed in the center of a front member so that the shaft is installed in the center, thereby maintaining the weight of the toe and heel portions equal, so that the toe and heel portions do not rotate but move in a straight line, thereby enabling accurate putting, and an open space portion is formed to reduce the weight and secure the center of gravity, while a removable weight portion is formed at the rear of the open portion so that the balance of the rotational inertia moment, which is important in the putter head, is maintained, thereby enabling the putter head to increase straightness by maximizing the use of inertia by the weight during putting.

The moment of inertia (MOI) generated by the putter head is an indicator of the magnitude of the tendency of an object rotating around its axis to continue rotating, and is affected by the size and distribution of the weight placed on the putter head.

A user's performance can be affected by MOI in that increasing the MOI of a golf club head can increase the resistance to unwanted twisting of the golf club head during off-center hits. Increasing the MOI of a putter head can help mitigate mistakes, and it is generally desired to increase the MOI of a putter head in a manner that the user desires.

The background technology of the present invention is Patent Registration No. 1532792 "Golf Putter Head and Detachable Putter Weight" (Patent Document 1). The background technology proposes a club head including "one or more detachable weights positioned in the sole portion of the club head, wherein a first weight of the one or more detachable weights is disposed on a heel portion of the club head, a second weight of the one or more detachable weights is disposed on a toe portion of the club head, and the one or more detachable weights have a triangular shape, and the triangular shape has a first side portion and a second side portion forming a 90° angle, the first side portion being disposed close to a side of the club head and the second side portion being disposed toward a rear portion of the club head; and a vibration damping element disposed between at least one of the one or more detachable weights and a surface of the club head."

However, the above background technology had a problem in that the shaft was not configured to cross the center line, so the toe portion became heavier relative to the shaft, causing an imbalance during the swing.

Below, the present invention is described in detail with reference to embodiments presented in the attached drawings, but the presented embodiments are exemplary for a clear understanding of the present invention and the present invention is not limited thereto.

The technical configuration of the present invention is described in detail according to the following preferred embodiments.

FIG. 1 is a perspective view of a golf putter head with a removable weight of the present invention with the weight removed, FIG. 2 is a plan view of FIG. 1, and FIG. 3 is a bottom view of FIG. 1.

The present invention comprises a front member (10), a rear member (20) formed at a predetermined distance in the width direction from the front member (10), side struts (310)(320) connecting longitudinal ends of the front member (10) and the rear member (20), respectively, and a central strut (330) connecting longitudinal central portions of the front member (10) and the rear member (20), and is configured such that an open space (350) is formed between each of the side struts (310)(320).

Fig. 8 is a plan view showing a state in which a weight is configured in the present invention, and Figs. 9 and 10 are cross-sectional views of Fig. 8.

In the present invention, as shown in FIGS. 8 and 9, a weight (50) is configured to be detachable and offset from the space (350) toward the rear member (20), thereby increasing stability when hitting by rotating the putter backwards, while also increasing straightness by placing the center of gravity toward the rear.

The front member (10) is configured to have a heel portion (110), a toe portion (120), and a striking surface (160) arranged on the front to strike a golf ball, similar to a typical putter, and a shaft fixing groove (130) formed at a certain depth in the center of the upper surface.

In the present invention, the front member (10) and the rear member (20) and the side struts (310) (320) connecting the two sides of the front member (10) and the rear member (20) are configured to have a rectangular shape in a plane, so that the front surface of the front member (10) is formed as a vertical surface, thereby minimizing the twisting of the head and increasing the straightness.

The rear member (20) is formed at a certain distance in the width direction from the front member (10), and is also formed in a rectangular shape on a plane to minimize the head's distortion, and is formed parallel to the front member (10) at a certain distance.

The front member (10) and the rear member (20) are connected at both longitudinal ends of the front member (10) and the rear member (20) with side struts (310) and (320), respectively, and the longitudinal central portions of the front member (10) and the rear member (20) are connected with a central strut (330).

Fig. 4 is a front view of Fig. 1, Fig. 5 is a back view of Fig. 1, Fig. 6 is a side view of Fig. 1, and Fig. 7 is a cross-sectional view along lines A-A, B-B, and C-C of Fig. 2, respectively.

An open space (350) is formed between the central strut (330) and the side struts (310) (320) by the side struts (310) (320) and the central struts (330), and this space (350) has a shape in which both the upper and lower portions are open.

In the present invention, in order to maintain a large moment of inertia while resolving left-right twisting, the putter head is configured to have a square shape in plane and to have a shape that is symmetrical left-right around the central strut (330).

In particular, in the present invention, since a space (350) is formed on each side with the central strut (330) as the center, a weight (50) is formed in the space (350) so that the center of gravity is shifted rearward toward the rear member (20).

That is, by configuring the weight (50) to be biased toward the rear member (20) in the space (350) and placing the center of gravity toward the rear, the user can reduce left-right twisting when hitting a golf ball, while increasing straightness when the shaft rotates from the rear to the front for hitting.

The striking surface (160) is a surface that strikes a golf ball and has multiple grooves formed to increase friction when striking the golf ball, prevent slipping, and reduce missed shots.

In particular, a weight adjustment groove (150) is formed at a certain depth on the lower surface of the central strut (330) to reduce the weight and ensure that the center of gravity is carried as far rearward as possible by the weight (50).

In the present invention, the balance between the left and right is maintained so that the toe portion (120) and the heel portion (110) do not rotate upon impact. On the upper surfaces of the front member (10), the rear member (20) and the central strut (330), a marking groove (140) is formed in a straight line at the center of the central strut (330) so as to be perpendicular to the longitudinal direction of the front member (10), thereby allowing the user to recognize the marking groove (140) and induce accurate putting.

In addition, in the present invention, the shaft fixing groove (130) is positioned at the longitudinal center of the front member (10), that is, at the portion where the central strut (330) is formed. In this way, by installing the shaft at the center, the weights of the toe portion (120) and the heel portion (120) are maintained equal, so that the toe portion (120) and the heel portion (110) do not rotate but move in a straight line, thereby enabling accurate putting.

Such a shaft fixing groove (130) is located at the center of the longitudinal direction of the front member (10), and may be formed at the exact center. However, since the user holds the shaft obliquely, the shaft fixing groove (130) is formed diagonally from the heel portion (110) to the toe portion (120), and the lower portion of the shaft fixing groove (130) is located at the center of the longitudinal direction of the front member (10), so that the shaft is located at the center of the putter.

The weight (50) is configured to be fixed to the space (350) using various known fixing means such as adhesion or bolting. After the weight (50) is inserted into the space (350), as shown in FIGS. 8 and 9, the end of the bolt (510) protrudes into the space (350) to apply pressure to the weight (50) so as to fix the weight (50) to the space (360). At this time, as shown in FIG. 3, a bolt fastening hole (290) may be formed to penetrate the space (350) from the outside of the rear member (20) so that the end of the bolt (510) protrudes into the space (350). This bolt fastening hole (290) may be formed in the side strut (310) (320), and a fastening hole may be formed in the weight (50) itself so that the end of the bolt (510) can be screw-connected to facilitate fastening of the bolt (510).

At this time, the weight (50) can be formed in various sizes so that the user can select a weight (50) of a desired weight or size and insert it into the space (350) for use.

A weight (50) like this can be formed over the entire height of the space (350), but if the center of gravity is too low, the ball may float when putting, so that the center of gravity is somewhat raised while the weight (50) can be stably placed, a step (351) is formed at a certain height from the rear member (20) where the weight (50) is formed to the center of the space (350), so that the weight (50) is placed on the step (351).

In this way, by placing the weight (50) on the upper part of the step (351), the weight (50) is stably installed in the space (350), and since the weight (50) is not formed on the lower part of the step (351), the center of gravity moves upwards, preventing the golf ball from flying into the sky when struck, thereby further increasing straightness.

In particular, as shown in Fig. 10, the weight (50) is configured to protrude downwards with an area that is a certain size smaller than the lower area of the weight (50) to form an additional weight portion (510), and is mounted on the step (351) so that the additional weight portion (510) protrudes downwards from the step (351), thereby moving the center of gravity as far back as possible to increase straightness.

At this time, in the case of the additional weight part (510), the lower surface is configured to be identical to the shape of the overall body, and the additional weight part (510) is configured to be integral with the weight (510) by placing a protrusion on the lower surface of the weight (50) so that it is placed on the protrusion (351).

In addition, as shown in FIG. 9, the weight (50) can be easily detached by forming a detachment groove (560) on the outer edge of the upper surface so that the weight (50) can be easily detached by using the detachment groove (560), and the weight (50) can be formed to be a certain size smaller than the size of the space (350) in plane so that a space (570) is formed between the side wall of the side strut (310)(320) or the central strut (330), so that the weight (50) can be easily inserted into the space (350).

In particular, the present invention is preferably formed into a rectangular shape on a plane, but in the case of the lower surface, since the corners of the front member (10) or the rear member (20) may hit the ground when putting, the outer corners in the width direction of the lower surface of the rear member (20) may be cut to form a rear inclined surface (180), and the outer corners of the lower surfaces of both longitudinal sides of the front member (10) and the side struts (310) (320) may be cut to form a side inclined surface (170).

The golf putter head having a removable weight of the present invention as described above is formed in a square shape so as to maximize the moment of inertia, and by forming a shaft fixing groove in the center of the front member so that the shaft is installed in the center, the weight of the toe and heel parts is maintained the same so that the toe and heel parts do not rotate but move in a straight line, thereby enabling accurate putting, and by forming an open space part to reduce the weight and secure the center of gravity, while forming a removable weight at the rear of the open part so as to maintain the balance of the important rotational moment of inertia in the putter head, the weight allows for maximum utilization of inertia during putting, thereby having a very useful effect of increasing straightness.

Although the present invention has been described in detail with reference to the presented embodiments, those skilled in the art will be able to make various modifications and variations without departing from the technical spirit of the present invention by referring to the presented embodiments. The present invention is not limited by such modifications and variations, but is only limited by the claims attached below.
