JP3134402U - Spiral weight for golf practice - Google Patents

Abstract

A ball can be actually hit, and can be mounted at an arbitrary position of a shaft due to an anti-slip effect of an elastic synthetic resin of a covering material, so that a club balance can be freely set.
By winding a weight 1 having a spiral structure around a shaft 2 and mounting it, the weight does not become an obstacle, so that it is possible to practice while actually hitting the ball, thus solving the above problem. It is possible to maintain the helical structure by forming a plastic metal plate such as lead into a helical structure and coating the surface with a rubber-like elastic synthetic resin. Due to the flexibility of the elastic synthetic resin, it can be freely wound and unwound around the shaft.

Description

  The present invention relates to a spiral golf practice weight that can be freely attached to and detached from a shaft of a golf club and can actually hit a ball while being attached.

  Conventional golf practice weights are exclusively used for swinging to be mounted on the head 4 and neck 3 of the golf club, and the weights become obstacles and it was impossible to actually hit the ball.

  The conventional weight for golf practice is not only to warm up by swinging but also to feel strength strengthening and swinging mainly on the trunk, but the attached weight becomes an obstacle with the ground and the ball and only swings. Can not. Since it is not possible to confirm whether or not the club is swinging with an appropriate swing trajectory by simple swinging, the swing of the wrong trajectory may be obtained. If the weight can actually hit the ball, it is easy to check whether the swing trajectory is appropriate by looking at the trajectory of the ball, and the strength can be strengthened, so that more effective practice can be performed.

  In the present invention, a spiral weight 1 is mounted on a shaft 2 as shown in FIG. 1 so that a ball can be actually hit. This weight is coated with a rubber-like elastic synthetic resin 6 on the surface of a plastic metal 5 such as lead, which serves as a weight, so that the helical structure is maintained and an appropriate weight necessary for warming up and strengthening muscle strength, It has moderate flexibility so that it can be wound and unwound along. Since it is wound around the shaft, the weight does not become an obstacle, so you can actually hit the ball. Therefore, by attaching weights with a detachable spiral structure, it is possible to effectively practice by hitting the ball at all clubs and checking the trajectory of the ball, so that effective training can be performed. The problem is solved.

  As described above, the helical structure weight of the present invention can actually hit the ball and can be mounted at any position on the shaft due to the non-slip effect of the elastic synthetic resin of the covering material, so that the club balance can be freely set. Can be set. Moreover, even though a stopper is unnecessary because it is wound around the shaft, it does not come off even with a strong impact of hitting the ball, and the impact on the shaft is also dispersed because it is in contact with the shaft on the surface, so the shaft breaks There is no safety. In addition, the weight can be adjusted according to the muscular strength because multiple wearing is possible. Furthermore, it can be installed not only on irons but also on all clubs such as wood and putters.

  The core of this weight has an appropriate balance between plasticity and elasticity by forming a plastic metal 5 such as a lead plate into a spiral shape and coating the surface with a rubber-like elastic synthetic resin 6 such as silicon. Thus, it is possible to have both a helical shape and flexibility. The weight and flexibility can be freely set by adjusting the thickness of the plastic metal and the elastic synthetic resin.

  When this weight is made heavy, the plastic metal 5 that becomes the weight is made thick, but in that case, it is prevented from becoming hard by making mesh-like cuts on the surface of 5 and has flexibility without making the coating material thick. be able to.

  Since a plurality of weights can be worn, if used step by step, warm-up and strength strengthening can be done without undue strain on the muscles. For example, for a junior or senior golfer who needs strength strengthening, use 50g per weight and two 100g weights, and practice lightly at 50g in the first stage and replace it with 100g in the second stage. By adding 50g in the third stage and making it a heavy load of 150g, you can practice step by step without difficulty. FIG. 10 shows an example in which a plurality are installed.

  A production example of this weight will be described next. A lead plate having a thickness of 1 mm, a width of 12 mm, and a length of 300 mm serving as a weight is spirally wound in accordance with the shaft diameter, soaked in an elastic synthetic resin solution, and then pulled up and dried to form a rubbery coating. When this dipping and drying are performed several times and the thickness of the coating becomes about 0.4 mm, a main weight having a length of 80 mm and a weight of about 50 g can be obtained while maintaining the helical shape and being flexible.

  The procedure for attaching the weight to the shaft is shown in FIGS. As shown in FIG. 5, the end of the weight is applied to the shaft, and the weight can be easily mounted by rotating the weight along the shaft in accordance with the spiral groove as shown in FIGS. By tightening both ends when winding is completed, the degree of adhesion with the shaft increases, and it can be mounted at any position on the shaft. Removal can be easily performed by rotating the weight in the reverse direction.

  The weight of the spiral structure of the present invention is easy to adjust the weight, attach and detach, and it is hard to come off during exercise and it is highly safe, so it is not only a golf club but also a badminton, tennis racket, bamboo sword, baseball bat etc. Available for sports hitting tools. An example of mounting on a badminton racket is shown in FIG.
