Description

Low wind resistance racquet frame

This creation is a racket, especially a low wind resistance racquet frame that utilizes a combination of multiple wind cut surfaces to achieve low wind resistance.

Both tennis and badminton are shots with a hand-held body. The faster the ball is hit, or the faster the rotation, the opponent needs to shorten the reaction time, preparation time, or need a faster swing speed. Effectively return the ball back. Increasing the swing speed is an effective method. The faster the swing speed, the faster the speed or the high level of the ball. In terms of competition, the players all want to increase the swing speed. Create more pressure on the field to the opponent.

In general, whether it is a tennis racket or a badminton racket, the frame is mostly oval or circular. Regardless of whether the frame is oval or round, during the swing process, the frame is subject to a large range of wind, and a large wind resistance is formed on the frame, which reduces the speed of the player's swing. Shooting fast or high-quality spheroids, or reducing the accuracy of hitting the ball, resulting in unstable ball control, can not give better strength; for beginners, when the body muscle endurance has not improved, repeat the practice The swing will cause a physical burden, or it may not be able to hit the ball accurately, or even cause a strain on the hand muscle due to the wrong force applied, resulting in a decrease in willingness to exercise.

In order to effectively reduce the wind resistance generated by the racquet during the swing, the author proposes a low wind resistance racquet frame, which can reduce the wind resistance when the racquet is swayed by using multiple wind cut surface structures on the racquet frame.

In order to achieve the above object, the present low wind resistance racquet frame comprises: a handle; a frame connecting the handle, the frame having an inner annulus, an outer annulus, a front surface and a rear surface, wherein The front surface and the rear surface are connected to the inner annular surface and the outer annular surface, and at least one air guiding region is formed on at least one of the front surface and the rear surface, and the air guiding region comprises a plurality of staggered continuous outer rows Wind cut surface and inner wind cut surface.

Each of the outer wind cutting planes comprises a first outer cutting plane and a second outer cutting plane, the first outer cutting plane being connected to the second outer cutting plane and recessed toward the inner annular surface, so that the outer wind cutting planes are on the plan view Presenting a V-shaped outward structure; each inner wind cutting surface includes a first inner cutting plane and a second inner cutting plane, the first inner cutting plane being connected to the second inner cutting plane and recessed toward the outer annular surface, The inner wind cut surface is v-shaped inwardly on the plan view; each outer wind cut surface and each inner wind cut surface are staggered and connected. With the combination of the wind-cut surfaces, when the racket is swung, the wind pressure on the windward side of the racket can pass through the cutting planes more unobstructed, and the wind resistance at the time of hitting the ball can be reduced, and the swing speed can be improved. Moreover, the wind-cut structure can be applied to different types of racquets such as badminton rackets or tennis rackets, and the wind resistance can be reduced.
