[Industrial applications]

 The present invention relates to a weight for adjusting a swing weight of a golf club, which is attached to a tip of a hosel or a shaft inserted into the hosel.

[0002]

[Prior art]

 As shown in FIG. 5, a known swing weight adjusting weight a is integrally molded in a substantially cylindrical shape with lead, and the weight a is inserted into the tip of the shaft b with an adhesive (not shown). It is fixed. The surface of the weight a integrally formed with lead is relatively smooth, so that the anchor effect of the adhesive is relatively small.

Therefore, according to this conventional technique, the adhesive a may be peeled off due to long-term use and the weight a may move freely in the shaft b. In such a case, the weight balance of the golf club may be lost. However, there is a problem that abnormal noise occurs due to the movement of the weight a.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 4, the swing weight adjusting weight 1 according to the present embodiment is integrally formed with a sintered metal, in particular, a sintered metal containing tungsten as a main material without machining. The main body 2 has a substantially cylindrical shape to be inserted into the tip portion 11a of the shaft 11, and the tip end surface 11b of the shaft 11 and the bottom surface 12b of the hollow portion 12a of the hosel 12 are integrally molded with the bottom end portion 2a of the body 2. It is provided with a flange portion 3 that is sandwiched between the weight 1 and a hole-shaped air vent 4 that axially penetrates the weight 1. Further, the weight 1 is seated on the bottom surface 12b of the hollow portion 12a of the hosel 12. According to the provision of the tapered seating surface 12c, the taper portion 5 is provided in advance on the lower end surface 1a of the weight 1. 13 is a socket.

As shown in FIGS. 3 and 4, the swing weight adjusting weight 1 having the above-described configuration inserts the main body 2 into the tip 11a of the shaft 11 and the hosel together with the tip 11a of the shaft 11. 12 is inserted into the hollow portion 12a of the hosel 12, the taper portion 5 is seated on the seating surface 12c of the hosel 12, and the flange portion 3 is sandwiched between the front end surface 11b of the shaft 11 and the bottom surface 12b of the hollow portion 12a of the hosel 12. It is fixed to both or at least one of the shaft 11 and the hosel 12 with an adhesive (not shown), and has the following effects.

That is, first, since the weight 1 is integrally formed of a sintered metal, in particular, a sintered metal whose main material is tungsten, the surface and the inside of the weight 1 become porous, and As a result, the anchor effect of the adhesive agent appears remarkably. Therefore, since the adhesive strength is improved along with this, it is possible to provide the swing weight adjusting weight 1 in which the adhesive is not easily peeled off and does not move within the shaft 11, and thereby the weight balance of the golf club. It is possible to prevent the noise from collapsing and the generation of abnormal noise due to the movement of the weight 1.

Further, a taper-shaped seating surface 12c for seating the weight 1 is provided on the bottom surface 12b of the hollow portion 12a of the hosel 12, and accordingly, the lower end surface 1a of the weight 1 is preliminarily provided with a taper portion 5a. When the weight 1 is mounted, the taper-shaped seating surface 12c and the taper portion 5 are aligned so that the weight 1 is concentric with the hosel 12. The weight 1 can be mounted on the hosel 12 at a correct position.

Further, a substantially columnar main body 2 to be inserted into the tip portion 11 a of the shaft 11 and a lower end portion 2 a of the main body 2 are integrally formed, and the tip surface 11 b of the shaft 11 and the hollow portion 12 a of the hosel 12 are formed. Since the flange portion 3 sandwiched between the bottom surface 12b and the bottom surface 12b is provided, the latter flange portion 3 is provided between the tip surface 11b of the shaft 11 and the bottom surface 12b of the hollow portion 12a of the hosel 12. By sandwiching the hosel 12 and the shaft 11 into one body, it is possible to reliably prevent the weight 1 from moving inside the shaft 11, and thereby the weight balance of the golf club is lost or the weight is lost. It is possible to prevent abnormal noise from being generated by the movement of 1.

Further, since the air vent 4 that penetrates the weight 1 in the axial direction is provided, the air in the hosel 12 can be extracted from the air vent 4 when the weight 1 is attached, and thus the attachment can be performed. The work can be facilitated.

[Effect of device]

 The present invention has the following effects.

That is, first, in the swing weight adjusting weight according to claim 1 or 2 of the present invention having the above-described structure, the weight is integrally formed of a sintered metal or a sintered metal whose main component is tungsten. Therefore, the surface and the inner part of the weight become porous, and the anchor effect of the adhesive agent appears remarkably by this amount. Therefore, since the adhesive strength is increased accordingly, it is possible to provide a swing weight adjusting weight that does not easily peel off the adhesive and does not move within the shaft, which contributes to the weight balance of the golf club. It is possible to prevent the sound from collapsing and the generation of abnormal noise due to the movement of the weight.

In addition to this, in the swing weight adjusting weight according to claim 3, a tapered seating surface for seating the weight is provided on the bottom surface of the hollow portion of the hosel, and accordingly, in advance, Since the lower end surface of the weight is provided with a taper portion, when the weight is mounted, the weight is attached to the hosel by aligning the tapered seating surface with the taper portion. Can be mounted concentrically, which allows the weight to be mounted in the correct position relative to the hosel.

In addition to this, in the swing weight adjusting weight according to a fourth aspect, a substantially columnar main body to be inserted into the tip end portion of the shaft and a tip end of the shaft integrally formed with the lower end portion of the main body. This latter flange is sandwiched between the tip of the shaft and the bottom of the hollow hosel because a flange is sandwiched between the surface and the bottom of the hollow hosel. By incorporating the hosel and the shaft into one piece, it is possible to reliably prevent the weight from moving within the shaft, which causes the weight balance of the golf club to be lost, and movement of the weight causes abnormal noise. Can be prevented.

In addition to this, in the swing weight adjusting weight according to the fifth aspect, since an air vent that penetrates the weight in the axial direction is provided, when the weight is attached, the weight is removed from the hosel inside the hosel. The air can be taken out, which can facilitate the mounting work.
