Description

  The present invention relates to a golf club of a type in which a tip of a shaft is inserted into a hole of a hosel of a head and is detachably fixed.

  The performance of the golf club is greatly influenced by the performance of the head and the shaft. Conventionally, the evolution of golf clubs has mainly focused on head performance, and research has been focused on the material, shape, dimensions, etc. of the head. The mainstay of further evolution will be on the shaft in the future. Although it is theoretically possible to determine what kind of shaft is attached to the head to obtain the best golf club for each golfer, in the end, various shafts are attached to the head. It is the most desirable method that each golfer decides by making a test shot. Therefore, for this purpose, there is a need for a golf club that can easily replace the shaft relative to the head.

  A golf club of a type in which the tip of a shaft is inserted into a hosel hole of a head and is detachably fixed is proposed in Patent Document 1. In this type of golf club, the shaft can be easily attached to and detached from the head, so that it is possible to make a trial hit by appropriately changing the shaft, and it can be used for the purpose of selecting the optimum shaft for the player.

  On the other hand, Patent Document 2 discloses a golf club having a configuration in which a shaft tip is inserted into a hosel hole of a head and a female screw formed inside the shaft tip is screwed into a bolt inside the hosel hole.

JP 2006-34906 A JP 2004-229795 A

  The golf club described in Patent Document 1 is configured such that a slit in the longitudinal direction is formed in the mouth portion of the hosel, and a tightening nut is screwed into a male screw formed in the outer peripheral portion of the hosel. By tightening the mouth portion of the hosel with a tightening nut, the tip of the shaft inserted into the mouth portion of the hosel is fastened and fixed. This golf club is easy to operate because the shaft tip can be attached to and detached from the hosel by tightening and loosening the nut, but tightening with the nut is only performed locally at the mouth portion of the hosel. Therefore, the shaft tip inserted into the hosel hole is easy to dance in the hosel hole. In this way, in a state where the shaft tip portion is easy to dance in the hosel hole, the normal golf club state, that is, the normal golf ball in which the peripheral surface of the shaft tip is entirely bonded and firmly fixed to the inner wall of the hole of the hosel. The state of the club is not reproduced. Therefore, even if the shaft is replaced and the nut is tightened to fix the shaft, the state in which the shaft is attached to a normal head is not accurately reproduced. The objective will not be fully achieved.

  On the other hand, in the golf club described in Patent Document 2, the shaft tip is fixed to the head by screwing between the female screw at the tip of the shaft and the male screw provided inside the hosel hole. This is not done to fix the tip of the shaft inside the hosel hole, but to adjust the longitudinal position of the shaft relative to the head in order to obtain an optimal dynamic balance between the shaft and the head. Thus, final fixing of the shaft tip inside the hosel hole is performed using an adhesive as in the prior art. Therefore, in the golf club described in Patent Document 2, the screwing of the female screw and the male screw is not for the purpose of making the shaft detachable but for the purpose of adjusting the dynamic balance. In the golf club described in Patent Document 2, a screw hole is formed in the heel surface (back surface) of the head for adjusting the position of the shaft with respect to the head, and the positioning tool and the position adjusting tool are inserted into the head through the screw hole. Therefore, it is necessary to introduce a structure which is not found in a normal head to the head, and the head is different from the normal head.

  The present invention has been made in order to solve the above-mentioned problems, and its purpose is to easily replace a shaft in an actual club and attach it by bonding, and without using an adhesive. An object of the present invention is to obtain a golf club with a detachable shaft that enables shaft exchange and allows a trial hit with the same feeling as a trial hit by shaft exchange in an actual club.

  According to the first aspect of the present invention, in the golf club in which the tip of the shaft is inserted into the hole of the hosel of the head and is detachably fixed, the hosel sleeve is fitted into the hole of the hosel concentrically with the hole of the hosel. One of a female engaging portion and a male engaging portion is fixedly provided on the inner end portion of the hosel sleeve concentrically with the hosel sleeve, and the shaft sleeve is provided on the outer periphery of the tip end of the shaft. Are fixed by fitting, and the other end of the female engaging portion and the male engaging portion are provided integrally at the tip of the shaft sleeve, concentrically with the shaft sleeve, and the shaft is provided inside the hosel sleeve. A sleeve is inserted, and the other one of the female engaging portion and the male engaging portion at the tip of the shaft is engaged with the one of the female engaging portion and the male engaging portion in the hole of the hosel. It is in, wherein the distal end of the shaft is fixed in the hole of the hosel.

  According to a second aspect of the present invention, in the golf club according to the first aspect, the female engaging portion is constituted by a female screw, and the male engaging portion is constituted by a male screw.

According to a third aspect of the present invention, in the golf club according to the first aspect, the one of the female engaging portion and the male engaging portion provided at the inner end portion of the hosel sleeve is the inner end of the hosel sleeve. The other of the female engaging portion and the male engaging portion integrally provided at the tip end portion of the shaft sleeve is a male screw.
According to a fourth aspect of the present invention, in the golf club according to the first, second, or third aspect, a rotation stopping means is provided to hold a rotational direction position of the shaft sleeve with respect to the hosel sleeve at a predetermined position. To do.
According to a fifth aspect of the present invention, the hosel comprises: a hosel sleeve fixed by fitting in a hosel hole of a golf club head; and a shaft sleeve fixed by fitting to a tip outer periphery of a shaft of the golf club; One of the female engaging portion and the male engaging portion is integrally provided at the base end portion of the sleeve, and the other of the female engaging portion and the male engaging portion is integrally formed at the distal end portion of the shaft sleeve. The hosel sleeve / shaft sleeve assembly is characterized in that the one of the female engaging portion and the male engaging portion can be engaged and disengaged.

  According to the first aspect of the present invention, the female engaging portion or the male engaging portion at the tip of the shaft engages with the male engaging portion or the female engaging portion in the hosel hole. It is constrained in the hosel hole, so that the shaft tip does not move in the hosel hole as in the prior art, and the shaft tip in the hosel hole is fixed in the hosel hole in the entire longitudinal region. Therefore, the golf club of the present invention equipped with the exchange shaft is attached to the head in the same state as a normal golf club, and when a golf club equipped with the exchange shaft is used for trial hitting, the characteristics are as follows. It can be judged accurately.

  Then, a hosel sleeve is fitted and fixed in the hole of the hosel concentrically with the hole of the hosel, and a female engaging part or a male engaging part is fixed to the inner end part concentrically with the hosel sleeve. On the other hand, a shaft sleeve is fixed to the outer side of the shaft tip by fitting, and a male engagement portion or a female engagement portion is fixed to the tip end concentrically with the shaft sleeve. Since the sleeve is inserted and fixed to the hosel sleeve, the fitting of both the sleeves causes the shaft side and the hosel side to be closely fitted to each other, and the connecting portion between them is mechanically strengthened. Further, the shaft sleeve and the hosel sleeve make it easy to attach and detach the shaft, and the shaft sleeve also serves as a member that complements the strength of the shaft.

  In addition, the golf club of the present invention does not require a work such as forming a screw hole in the bottom surface of the head and the head itself is not subjected to special processing, so that the state of the normal golf club is maintained. The shaft can be easily exchanged, and the state of the club before and after the shaft exchange is not different from that of a normal club. Therefore, the characteristics can be correctly determined by trial hitting.

  Further, the shaft can be easily replaced without using an adhesive without substantially changing the weight of the entire golf club or the configuration other than the hosel part.

  According to the second aspect of the present invention, the female engaging portion is constituted by a female screw, and the engaging portion is constituted by a male screw, whereby the constraint of the shaft with respect to the hosel is further strengthened by the coupling by both screws. It is possible to reliably prevent the head from coming off the shaft when performing a test hit using a club.

  According to the third aspect of the present invention, it is possible to easily and easily process the internal thread and the external thread on the inner end portion of the hosel sleeve and the distal end portion of the shaft sleeve.

  According to the fourth aspect of the present invention, the shaft can be fixed at a predetermined position with respect to the head by providing the rotation stopping means for holding the rotational direction position of the shaft sleeve with respect to the hosel sleeve at the predetermined position.

  According to the invention of the fifth aspect, the same effect as that of the first aspect can be obtained.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a golf club according to the present invention. The golf club G is composed of a head H and a shaft S. The shaft S has a grip Gr. The head H is integrally provided with a hosel h. The distal end portion of the shaft S is inserted into the hole of the hosel h, and can be attached to and detached from the hosel h as will be described later.

  2 and 3 show the structure of the tip of the shaft S inserted into the hole of the hosel h. As shown in FIG. 3, the shaft S is a hollow cylinder, and the hollow internal space of the shaft S is normally open at the tip. However, whether it is open or not is not important in the present invention. A hollow shaft sleeve 2 is fitted on the outer peripheral surface of the tip of the shaft S. A male screw 3 forming a bolt-like protrusion is provided at the tip of the shaft sleeve 2 concentrically with the shaft sleeve 2 in an integral and fixed manner. The male screw 3 constitutes a male engaging portion.

  In the illustrated embodiment, a tip wall 4 is integrally provided at the tip of the shaft sleeve 2, and a bolt-shaped male screw 3 is formed integrally with the tip wall 4 and protrudes in the longitudinal direction of the shaft sleeve 2. The shaft sleeve 2 is formed, for example, by forming a hollow hole 5 in a solid bar material by cutting the tip wall 4 away from the tip wall 4, and forming a male screw 3 by cutting on the outer peripheral portion of the tip portion from the tip wall 4. Can be produced. The inner diameter of the hollow hole 5 is determined so that the shaft S can be fitted into the hollow hole 5 through a very small gap. That is, the inner diameter of the hollow hole 5 is a diameter that allows the shaft S to be fitted into the hollow hole 5 via the adhesive layer 6.

  A state in which the shaft sleeve 2 is fitted on the outer peripheral surface of the tip of the shaft S is shown in FIG. The tip of the shaft S is fitted into the hollow hole 5 until it contacts the tip wall 4 with the adhesive layer 6 interposed therebetween. When the shaft S is fitted into the shaft sleeve 2, an adhesive such as an epoxy resin is applied to the tip of the shaft. In this way, the shaft sleeve 2 integrally having the protruding male screw 3 is integrally fixed to the outer peripheral surface of the tip of the shaft S. The male screw 3 is concentric with the shaft S. The shaft sleeve 2 is preferably made of ABS resin, PP resin, plastic such as nylon, or metal such as aluminum or titanium alloy.

  FIG. 4 shows the internal structure of the hosel h of the head H. The shaft S and the shaft sleeve 2 are indicated by phantom lines in the figure. As is known, the hosel h protrudes integrally with the main body of the head H, and the tip portion including the shaft sleeve 2 of the shaft S is inserted into the cylindrical hollow hole of the hosel h and fixed. Although there is a structure in which the hosel h does not protrude from the head H in a neck shape, a cylindrical portion into which the shaft S can be inserted is provided at a portion corresponding to the hosel h.

  The hosel sleeve 10 is fitted into the hole of the hosel h, and the hosel sleeve 10 is fixed to the inner surface of the hosel h by bonding through the adhesive layer 11. The hosel sleeve 10 is preferably fixed to the hosel h such that its outer end protrudes from the hole of the hosel h by a certain length (for example, 20 mm or more). The hosel sleeve 10 is fixed by being fitted into a hole in the hosel h with an adhesive such as an epoxy resin applied to the outer surface thereof. It is desirable to make a spiral cut in the hole of the hosel h that can receive the adhesive. The hosel sleeve 10 is preferably made of ABS resin, PP resin, plastic such as nylon, or metal such as aluminum or titanium alloy.

  The hosel sleeve 10 integrally has an inner end wall 12 at a base end portion, that is, an inner end portion. The hosel sleeve 10 can be manufactured by, for example, forming a hollow hole 13 in a solid bar material by boring, leaving the inner end wall 12. The inner end wall 12 is preferably formed thicker than the peripheral wall of the hosel sleeve 10, and a female screw 14 is formed in the center of the inner end wall 12 by cutting. Instead of forming the internal thread 14 directly on the inner end wall 12 as shown in FIG. 4, a nut 15 having an internal thread 14 is fitted into a hole formed in the center of the inner end wall 12, as shown in FIG. The hosel sleeve 10 may be fixed concentrically. The nut 15 can be fixed to the inner end wall 12 by welding, bonding or the like. The female screw 14 constitutes a female engaging portion.

  In the hollow hole 13 of the hosel sleeve 10 in the hosel h configured as described above, the shaft sleeve 2 fixed to the tip of the shaft S indicated by the phantom line in FIG. 4 is inserted in the direction indicated by the arrow A. The shaft sleeve 2 at the tip end of the shaft S is slid into the inner surface of the hosel sleeve 10 fixed in the hosel h without any gap. Accordingly, the outer diameter of the shaft sleeve 2 is substantially equal to the inner diameter of the hosel sleeve 10.

  When the tip of the male screw 3 forming the bolt-shaped protrusion of the shaft sleeve 2 reaches the female screw 14, the shaft S and the shaft sleeve 2 are rotated so that the male screw 3 is screwed into the female screw 14. As a result, while the male screw 3 is screwed into the female screw 14, the shaft sleeve 2 advances while sliding in the hosel sleeve 10, and finally the state shown in FIG. 6 is obtained. The male screw 3 being screwed into the female screw 14 means that the male engaging portion and the female engaging portion are engaged.

  Thus, the shaft S is fixed so as not to advance and retract in the axial direction in the hole of the hosel h via the shaft sleeve 2 and the hosel sleeve 10 at the tip thereof. The threaded engagement of the male screw 3 and the female screw 14, that is, the engagement between the male engaging portion and the female engaging portion, reliably prevents the shaft S from coming off the hosel h. The close fitting of the shaft sleeve 2 and the hosel sleeve 10 ensures this, and holds the shaft S in the hosel sleeve 10 through the shaft sleeve 2 in a stable state.

  In order to obtain the designed length of the club in the hole of the hosel h, it is necessary to insert and fix the shaft sleeve 2 to a predetermined depth position. In order to keep the center of gravity position of the head at the designed predetermined position, as shown in FIG. 7, when the inner shaft sleeve 2 rotates to the predetermined rotational position with respect to the outer hosel sleeve 10, The key 20 for fixing the rotational position is slid in the axial direction in a key slit formed in the shaft sleeve 2 and the hosel sleeve 10 in the axial direction so as to fix the relative rotational positions of both sleeves. The key slit is formed through the peripheral walls of both the sleeves 2 and 10 from the upper edge of the shaft sleeve 2 and the hosel sleeve 10 in FIG. 6 over a predetermined length in the axial direction. A key groove can be formed as a key receiving portion for inserting the key 20, but when the peripheral walls of the sleeves 2 and 10 are too thin to form the groove, it is desirable to form a key slit.

  The key 20 constitutes a rotation stop means of the shaft sleeve 2, and is preferably provided at a position facing the diametrical direction (at an angular interval of 180 °). As shown in FIG. 6, the key 20 is formed in, for example, an L shape, and the L-shaped projecting portion is gripped by hand, and is slid into the opposed key slits from the outer end face sides of the sleeves 2 and 10. Make it.

  The rotation stop means of the shaft sleeve 2 can also be constituted by a rotation stop pin 21 shown in FIG. A pin hole that can be aligned in the radial direction is formed on both sleeves 2 and 10 outside the hole of the hosel h, and the pin hole is aligned and the anti-rotation pin 21 is positioned in both the Oin holes in the radial direction. The relative rotational positions of the sleeves 2 and 10 are fixed by inserting the sleeves 2 and 2. The pin hole is formed, for example, at a position about 10 mm from the outer end of the hosel sleeve 10. When pin holes are formed in both sleeves 2 and 10, since the rotation stop pin 21 also penetrates the shaft S, in order to increase the strength of the shaft S, a cylindrical shaft liner is provided on the inner surface of the shaft S. Is preferred. As the material of the shaft liner, plastics such as ABS resin, PP resin and nylon, or metals such as aluminum and titanium alloy are used.

  In order to further secure the fixing of the shaft S to the hosel h, as shown in FIG. 6, a male screw 30 is formed on the outer periphery of the tip end portion of the hosel h, and the holding plate nut 31 fitted on the outer periphery of the shaft S is formed. It is desirable to screw the inner female screw to the male screw 30. As a result, the key 20 can be suppressed and concealed by the countersunk nut 31. Further, when the rotation stop pin 21 is provided, it can be hidden.

  FIG. 8 shows a modification of the above embodiment. In this modified embodiment, a cylindrical head 16 having an enlarged diameter is formed integrally with a bolt-shaped male screw 3 that is a male engaging portion, and the enlarged head 16 is formed in an adhesive layer inside the hole of the shaft sleeve 2. Glued and fixed by 17. On the other hand, the nut 15 that gives the female screw 14 that is a female engaging portion fixedly provided on the hosel sleeve 10 is given an outer diameter slightly smaller than the inner diameter of the hosel sleeve 10, and the nut 15 is placed in the hole of the hosel sleeve 10. It is bonded and fixed by the adhesive layer 18. As with any embodiment, the male and female engagement portions are preferably made of ABS resin, PP resin, plastic such as nylon, or metal such as aluminum or titanium alloy.

  FIG. 9 shows another variant embodiment of the invention. In this modified embodiment, in place of the male screw 3 which is the male engaging portion provided in the shaft sleeve 2 in the above-described embodiment, a female screw 3a as a female engaging portion is provided, and the female screw 14 provided in the hosel sleeve 10 is provided. Instead, a male screw 14a is provided. That is, in this modified embodiment, screwing by screws is reversed for the female and male in the above embodiment. As described above, in the present invention, when one of the screws is screwed into a female screw, the other is a male screw. When the male screw is used on either one of the shaft sleeve 2 and the hosel sleeve 10, the other side is used. The female screw will be used.

  9, the nut 40 having the female screw 3a is fixed to the inside of the shaft sleeve 2 by fixing means such as an adhesive layer 41, and the enlarged base 42 having the bolt-shaped male screw 14a is fixed to the adhesive layer 43 or the like. It is fixed inside the hosel sleeve 10 by means.

  FIG. 10 shows still another modified embodiment. In the embodiments described so far, a female screw is used as the female engaging portion, and a male screw is used as the male engaging portion. However, the female engaging portion and the male engaging portion are not screws, but are holes and bolts without screws. You may comprise by protrusion, respectively. 10 is basically similar to FIG. 4, but in the case of FIG. 10, the inner end wall 12 of the hosel sleeve 10 is formed with a screw-free hole 14b as a female engaging portion, and the shaft sleeve In FIG. 2, a bolt-like protrusion 3b without a screw is formed as a male engaging portion. The configuration shown in FIG. 10 corresponds in principle to the configuration shown in FIG. 4 except that there are no screws in the female engagement portion and the male engagement portion. Therefore, the description of the configuration of other parts in FIG. 10 is omitted. In the modified embodiment of FIG. 10, since there is no engagement by a screw, even if the bolt-shaped protrusion 3b is fitted inside the hole 14b, the force that constrains the shaft S to the hosel h in the axial direction is not applied to the shaft S. weak. Therefore, it is necessary to prevent the shaft S from coming out of the hosel h by using the restraining means such as the key 20, the rotation stopping pin 21, and the holding plate nut 31 already described.

  In the modified embodiment shown in FIG. 10, the shaft sleeve 2 is formed with a bolt-like protrusion 3b as a male engaging portion, and the hosel sleeve 10 is formed with a hole 14b as a female engaging portion. In this case, the shaft sleeve 2 can be provided with a hole as a female engaging portion, and the hosel sleeve 10 can be provided with a bolt-like protrusion as a male engaging portion. In this case, a configuration similar to that shown in FIG. 9 is adopted except that there is no screw.

  Although the present invention has been described with respect to various embodiments, in the present invention, the shaft tip is fitted into the hole of the hosel, and the base portion of the shaft tip is held in the hosel hole. Since the engaging portion or the male engaging portion engages with the male engaging portion or the female engaging portion in the hosel hole, the shaft is also restrained in the hosel hole at its most distal end portion, and thus the shaft tip as in the conventional one is used. The shaft does not move in the hosel hole, and the tip end of the shaft in the hosel hole is fixed in the hosel hole in the entire longitudinal direction. Therefore, the golf club of the present invention equipped with the exchange shaft is attached to the head in the same state as a normal golf club, and when a golf club equipped with the exchange shaft is used for trial hitting, the characteristics are as follows. It can be judged accurately.

    Further, a hosel sleeve is fitted and fixed concentrically with the hosel hole in the hole of the hosel, and a female engaging portion or a male engaging portion is fixedly provided at the inner end portion concentrically with the hosel sleeve. On the other hand, a shaft sleeve is fixed to the outer side of the shaft tip by fitting, and a male engagement portion or a female engagement portion is fixed to the tip end concentrically with the shaft sleeve. Is inserted and fixed to the hosel sleeve, so that the fitting of both sleeves makes the shaft side and the hosel side closer to each other, and the connection part between them is mechanically stronger and more stable. It will be. Further, the shaft sleeve and the hosel sleeve make the shaft attaching / detaching operation smooth and easy.

  In addition, the golf club of the present invention does not require a work such as forming a screw hole in the bottom surface of the head and the head itself is not subjected to special processing, so that the state of the normal golf club is maintained. The shaft can be easily exchanged, and the state of the club before and after the shaft exchange is not different from that of a normal club. Therefore, the characteristics can be correctly determined by trial hitting.

  Furthermore, when the female engaging portion is constituted by a female screw and the engaging portion is constituted by a male screw, the shaft is more restrained against the hosel when the two are screwed together. It is possible to reliably prevent the head from coming off the shaft.

  In addition, when the female engaging portion is configured by a hole and the male engaging portion is configured by a bolt-like protrusion, the shaft is securely restrained to the hosel and the shaft tip is prevented from being distorted while having a simple structure. be able to.
