Description

Weight clip for badminton racket

The present invention relates to a badminton racket, and more particularly to a weight clip of a badminton racket that can effectively strengthen the wrist muscles by varying the weight of the badminton racket head according to the training intensity.

In general, a badminton racket, as shown in Figure 2, the racket (Head) (210), the shaft (Shaft) 220, and the grip (Grip) wound around the cloth or leather so that the racket held in the hand does not slip The racket head has a hollow frame structure with a string or a gut, which is a portion where the shuttlecock is impacted, and is made of a head frame to which the racquet is tied.

The swing speed of the badminton racket comes from the snap action of the wrist holding the racket momentarily, and the racket is composed of a soft and thin shaft 220 and a slim racket head for a smooth hitting feeling and accurate control with power through the snap action. This is generally preferred.

These badminton rackets use a lot of new materials such as graphite, carbon, boron, and titanium, which are excellent in durability and elasticity, but also light in weight.

However, prior to the selection of a light, durable and resilient badminton racket, in order to play badminton, it is necessary to develop a wrist force capable of hitting the shuttlecock momentarily strong and accurate. Conventional badminton rackets are light in weight and have a center of gravity. There is a problem that is not suitable for exercise to strengthen wrist muscles because it is not in the racket head.

Also, if you use a head heavy type or stiff shaft racket (such as a squash racket) for practice, you can increase the power of your wrist, but the racket has a different grip than usual racket. Because the racket head's center of gravity is different, it actually poses a huge problem in optimizing the game.

Looking at the prior art associated with such a conventional problem, Korean Utility Model Model No. 20-0279060 (Registration date 2002.06.07, hereinafter referred to as "Document 1"), the receiving groove for receiving the end of the frame of the badminton racket head is formed In addition, a seating space is formed in one side of the receiving groove to be opened in one direction so that a neck is seated, and an air resistance member of a badminton racket is fixed to the top of the seating space with a Velcro tape.
