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 head (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 ( 230, the head has a hollow frame structure with a string or a gut, which is a part of the shuttlecock to be impacted, and is made of a head frame to which the guts are tied.

The swing speed of the badminton racket comes from the snap action of the wrist that grasps the racket momentarily, and the racket is composed of a soft and thin shaft 220 and a slim head frame for precise control with power and a soft hit 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 head of the racket.

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. Since the center of gravity of the head is different, it poses a huge problem in optimizing the game.
