Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a weight for golf swing practice, and more particularly to a weight for golf swing practice that can be easily attached to a shaft of a golf club during golf swing practice and enhances muscle strength and physical strength of a user.

[0002]

[Prior art]

 As described in Korean Utility Model Publication No. 1995-10302, a weight for golf swing practice that is used by being attached to a golf club is known. FIG. 7 shows a weight for golf swing practice according to the known example. A golf club 1 to which the weight is attached includes a shaft 2, a grip 3 provided at an upper end thereof, and a lower end of the shaft 2. And a head 4 coupled to the head.

As shown in FIG. 7, a weight for golf swing practice includes a support 11 mounted on a joint 5 between the shaft 2 and the head 4 of the golf club 1, and the support 11 is fitted to the support 11. And the weight body 12 which is formed. The support 11 is made of a material having some elasticity (for example, rubber), and is formed in a ring shape. An enlarged diameter portion 13 is provided at a lower portion of the support 11, and an opening 14 is formed in the support 11, and the support 11 is connected to the joining portion 5 of the golf club 1 through the opening 14. It can be installed from the side.

On the other hand, the weight body 12 is formed in a ring shape having a through hole, and the grip 3 of the golf club 1 can pass through the through hole. Therefore, after attaching the support 11 to the joint 5 of the golf club 1 and inserting the shaft 2 of the golf club 1 from the grip 3 side into the through hole of the weight 12, the weight 12 is moved along the shaft 2. The weight body 12 can be fitted to the support 11 from above by moving to the support 11 side.

[0005]

[Problems to be solved by the invention]

 The weight having such a configuration can be attached to the golf club 1 and used for swing practice. However, during the swing practice, the weight of the weight body 12 pushes the support 11 toward the head 4 side of the golf club 1. As a result, an excessive force may be applied to the head 4 and the head 4 may come off from the shaft 2.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a weight for golf swing practice that can be easily attached to a golf club shaft during golf swing practice and that can enhance the user's muscle strength and physical strength. I do.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a weight for training a golf swing which is mounted on a golf club shaft and used for practicing a golf swing. A fixing protrusion is formed on the portion, a protrusion having a predetermined thickness is formed on one side from the lower end to the upper end, and an opening that becomes wider toward the upper end is formed on the other side from the lower end to the upper end. A fixing member formed from the side and attached to the shaft of the golf club through the opening, having a predetermined weight, and having a diameter closer to the upper end so as to fit tightly on the outer peripheral surface of the fixing member. It has an inner peripheral surface that is reduced, and has a coupling portion on one side into which the protruding portion of the fixing member is fitted, and a weight body that can be fitted to the fixing member.

[0008]

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a weight for golf swing practice according to a first embodiment of the present invention. This weight can be used for a general golf club 1 and can be used for any of the shafts 2 of the golf club 1. It can be freely mounted and fixed at any position.

The weight for golf swing practice includes a fixed member 100 that is densely mounted on the shaft 2 of the golf club 1, and a weight body 200 that is closely fitted to the fixed member 100. The fixing member 100 is made of a material such as rubber having high elasticity. As shown in FIGS. 1 and 2, a fixing protrusion 101 having a large diameter is formed at a lower end of the fixing member 100, and the detachment of the weight body 200 from the fixing member 100 during a swing is prevented by the fixing protrusion 101. Further, the fixing member 100 has a projection 102 and an opening 103 formed thereon, so that the fixing member 100 can be easily attached to the shaft 2 of the golf club 1 from the side through the opening 103. The protruding portion 102 is adapted to fit tightly into the coupling portion 201 (FIG. 3) of the weight body 200.

The fixing member 100 is formed in a hollow truncated conical shape such that the outer diameter becomes smaller toward the upper side, and has an inner diameter slightly smaller than the diameter of the shaft 2, and as shown in FIG. The shaft 2 is strongly tightened by the elastic force of the fixing member 100 when the shaft 2 is mounted. The opening 103 of the fixing member 100 is wider toward the upper side of the fixing member 100, so that the user can easily spread the opening 103 by hand to mount it on the shaft 2.

On the other hand, the weight body 200 is formed by coating an inner core with a material such as rubber having high elasticity, and is formed in a hollow cylindrical shape as shown in FIG. It has the same height as the height of the member 100 (FIG. 4). The weight body 200 has an inner diameter that becomes smaller toward the upper side, that is, a frusto-conical inner peripheral surface, and is brought into close contact with the frusto-conical fixing member 100 (FIG. 4). The weight body 200 has a connecting portion 201 that defines a space having the same width as the protruding portion 102 of the fixing member 100, and the protruding portion 102 fits into the connecting portion 201. The user can easily attach the weight body 200 to the fixing member 100 from the side or above by spreading the connecting portion 201 by hand.

Next, a weight for golf swing practice according to a second embodiment of the present invention will be described. The weight according to the second embodiment uses the fixing member 100 shown in FIG. 2 in combination with the weight body 200 shown in FIG. 5, and is attached to the golf club shaft 2 as shown in FIG. Is done. The weight body 200 shown in FIG. 5 has the same basic structure as that shown in FIG. 3, except that it has the same height as the fixing member 100 and has a peripheral step 202 at the lower end thereof. Different.

The peripheral step portion 202 of the weight body 200 has the same height as the fixing protrusion 101 of the fixing member 100 and has an inner diameter substantially the same as the outer diameter of the fixing protrusion 101, and surrounds the fixing protrusion 101. It has become. When the peripheral step 202 of the weight body 200 and the fixing protrusion 101 of the fixing member 100 are fitted, the fixing member 100 and the weight body 200 are more firmly connected.

[0014] The preferred embodiment of the present invention has been described above. However, the weight for golf swing practice of the present invention can be variously modified within the technical concept thereof.

[0015]

[Effect of the invention]

 According to the present invention, it is possible to provide a weight for a golf swing practice that can be easily attached to a golf club shaft during a golf swing practice and to enhance a user's muscular strength and physical strength. The weight member for golf swing practice is pushed toward the golf club head side during golf swing practice by a sufficient tightening force and frictional force because the fixing member having the weight and the weight body can be combined and mounted on the golf club shaft. That can be prevented.
