Description

[Detailed description of the invention] Improvement of golf clubs The present invention relates to golf clubs.

Golf clubs come in many different styles, such as the shape of the club head, the stiffness of the shaft, etc. The weight of each swing weight varies in terms of weight, so-called swing weight, etc., and generally each Each golfer's needs are different. Most of the problems so far have been Stores allow individuals to rigorously try out and find clubs that ideally fit them. To keep a sufficiently large range of clubs in stock that can be dispensed. It was said that it was not possible.

The present invention includes a club head assembly, an elongated shaft assembly, and a shaft assembly. A hole in the club head assembly to receive one end and a hole in the club head assembly to receive one end. Holding the shaft assembly in place, the temporarily assembled golf club actually a releasable means of sufficient security for use; the means has a pushing means insertable into the club head assembly, the shaft assembly and pushing the shaft assembly into engagement with the hole; a golf club, the golf club being provided with a means for retaining a steering means to a club head assembly; provide.

Can be assembled in a temporary manner and the golf club can actually be used By providing golf clubs that are safe enough to Before love is actually completed, each individual must find the ideal combination for themselves. Opportunity to try as many different clubhead and shaft combinations as necessary to can be given to each individual, in this way each individual effectively owns his or her club. It can be modified to suit your requirements.

In a more particular form of the invention, a club head assembly and an elongate shaft assembly are provided. a hole in the club head assembly for receiving one end of the shaft assembly; Ensure that the temporarily assembled golf club is sufficiently safe for actual use. a releasable shaft assembly that holds the shaft assembly in place in the clubhead assembly hole. means, the releasable means engages the shaft assembly and a pushing means insertable into the club head assembly to push the object into the hole; The shaft assembly includes an elongated shaft, and the shaft assembly includes an elongated shaft, and the shaft assembly includes an elongated shaft. a cylindrical outer surface is provided at said one end of the shaft assembly for engagement with the bore; The axis of the side surface is located at an angle to the longitudinal axis of the shaft so that The rotational position of the shaft assembly within the hole is determined by the assembled club's life and Determine the face angle and position the shaft assembly in front of the clubhead assembly. Means is provided for holding the marking hole in a selected one of a plurality of rotational positions. Golf clubs of the following types are provided.

By way of example, one embodiment of the invention will be described below with reference to the accompanying drawings.

FIG. 1 is a partially cutaway exploded view showing the constituent parts of the golf club of the present invention; FIG. 2 is a partial cutaway view of the assembled club.

The components of a golf club can be seen in Figure 1 and may be made of wood, metal or plastic, for example. an elongate shaft assembly comprising a shaft 14 of a material having one end thereof A club head comprising a club head 10 having a neck portion 12 that fits into a club head. Contains assembly. hole! An OA is provided at Club Rad 10 and can be seen in Figure 2. The shaft assembly is adapted to receive one end of the shaft assembly. The diameter of hole 10A is larger than the shaft diameter. The shaft assembly receives the end of shaft 14 It includes a cylindrical bushing 16 having a hole 16A for inserting. Bush 16 is an example It is permanently attached to the shaft, 14, for example by adhesive. In this case it is circular The outer cylindrical surface 16B of the bushing 6 has a cross-section that extends into the hole 10 of the club head 10. It is designed to engage with A.

Here, the axis of the hole i6A is relative to the axis of the outer surface 16B of the bushing 16. A hole is drilled into the bushing 16 such that the bushing 16 is positioned at an angle. In Figure 1, This angle or "bias" is denoted by angle a. This “bias” affects the lie and fly of the club. By changing the face angle and the rotational position of the bushing in the clubhead hole. This is so that it can be adjusted as desired.

This arrangement structure is described in the applicant's earlier application, the description of which is incorporated herein by reference. UK Patent Application No. 2197209.

This club head assembly is received in the major portion 10B opposite the hole 10A of the neck portion 12. It includes a color 13. This collar 13 is attached to the club using adhesive, for example. permanently fixed to the head 10.

Collar 13 has an axially extending surface discontinuity on its inner surface 13A, e.g. It has a line. A portion 16C of the bushing 16 has a surface free surface on its outer surface. Continuities, e.g. splines, are provided, these splines extending over the outer surface of the bushing. It extends axially with respect to the axis of 16B. Surface imperfection of collar 13 and bushing 16 The continuous portions are connected to each other when the bushing is inserted into the hole 10A of the club head 10. engageable and these discontinuities also connect the bush and the shaft to the club. It serves to hold the head in a predetermined rotational position relative to the head.

In the drawing, the portion 16C of the bushing 16 is slightly smaller than the rest of the bushing. It has a large outer diameter and this means that the bushing is located most in hole 10A of the club head. You will see that this means that it can be inserted only the first distance and rotation is not hindered. . Once the desired rotational position of the bushing 16 is established, it is fully inserted and 1. so that the collar 13 and bushing 16 are more engaged with each other; : can Ru. This position can be seen in FIG.

Here, a notch 11 is provided in the bushing, for example, the lie of the club is the most ゛)゛ Display the reference point at the rotation position that will become the tube light 12, and press the button 1. After fixing 6, the label is placed on ``4'' and ``upright'' and ``flat'' are placed. [] to display the lie of the club between "lat" and "open" and "close". ” so that a mark of 7 can be obtained.

Other constructions of the collar and bushing may be used instead of the round cross-section of the spline engagement, e.g. It will be appreciated that the bushings and bushings can have a polygonal cross-section. Probably. Additionally, other methods of obtaining "bias" for the shaft may be provided. Wear.

retaining the bushing 16 and thus the shaft assembly within the club head assembly Therefore, according to the invention, pushing means are provided, which means here are threaded fasteners. This is the format of the tool 20.

A hole 21 is drilled in the club head 10 for inserting the fastener 20.

This hole 21 is drilled through the bottom 10C of the club head 10 so as to fit into the hole 10A. and the axis of hole 21 is aligned with hole 1. Make it intersect with the axis of OA. This is When the foot assembly is in place in the hole 10A of the club head assembly, the fastener 20 The fastener threads can engage the outer surface 16B of the bushing 16 and Enables interlocking engagement with the outer surface. Here, the fastener 20 are threaded parallel to each other, and the axis of hole 2 is parallel to the axis of hole 10A of the club rad 10. The angle is set so that it forms an angle of ing. This arrangement structure allows the bushing 16 to Hole 1 of the club head. This means that it works to push the OA into engagement. . 'i, The mating engagement of the fastener thread with the outer surface of the bushing is ensured when the fastener is inserted. The more it is inserted, the more deeply it becomes. 7 This angle is relatively small, e.g. 4.5°. , so that the fasteners 20 touch the outer surface of the bushing 16 for a sufficient distance. or to obtain a satisfactory grip. Putushi, ]60 1, the lower part of the side surface has surface irregularities - 8, for example splines 4, and This causes the screw of the fastener to penetrate as it cuts into the outer surface of the bushing. To increase the meshing engagement of the two.

The sloping arrangement of the C- fasteners acts like the jaws of a fishhook and also The connection between the love head will become looser. ・Unako 2- is pushed even if it is 4)-7. 5, which means that it is possible to prevent the ball from slipping out of the club. i) Deaf.
