Description

Artificial feathers for badminton

The present invention relates to the structure of badminton, in particular to artificial feathers of badminton.

The structure of a badminton can basically be divided into two parts: the "head" and the "feathers". The head is a cylinder with a semi-spherical front end. It is the part where the badminton and the racket face come into contact. The racket face is a net made up of special lines arranged vertically and horizontally. The feathers are evenly inserted at the end of the head and neatly arranged into a cone-like structure. The current general specification of badminton uses 16 feathers.

According to the classification of badminton materials, they can basically be divided into two types: natural materials and artificial materials. The price of badminton made of natural materials is relatively higher than that of badminton made of artificial materials. Therefore, badminton made of natural feathers is mostly used in competitions, while badminton made of artificial materials can be used as a practice ball for beginners.

Natural feathers are usually goose or duck feathers. The collection, sorting and processing of natural feathers are difficult, which makes them more expensive. In order to maintain the stability of the badminton flight during the game, the slight wear and tear of the badminton feathers will affect the flight trajectory and must be replaced immediately. During the high-intensity game process, the consumption of badminton will remain high.

In the approved (certificate number TW I713740) invention patent of the Republic of China, "Artificial feathers for badminton, and badminton", the feather part of the artificial feather proposed therein can be formed by non-woven fabrics or resins. When non-woven fabrics are used, a reinforced film is formed on the surface to prevent the fibers of the non-woven fabric from unraveling when hitting the ball. The reinforced film can be formed by applying resin.

In the approved (certificate number TW I636815) invention patent of the Republic of China "Badminton and its shaft", the badminton includes a plurality of bristles, a ball head and a plurality of the bristle shafts, the bristle shaft includes: a shaft body having a bristle end and a ball head end, the shaft body is made of plastic material, and one of the bristles of the plurality of bristles is joined to the bristle end. The shaft includes: a hollow tube having an upper top surface and a lower top surface; a receiving channel located in the hollow tube; and a pair of side wings respectively connected to the two side surfaces of the hollow tube facing opposite directions. The side wings are sheet-like structures respectively connected to the two side surfaces of the hollow tube facing opposite directions. The pair of side wings can be used for each feather piece to be stably connected thereto; and a foam material filled in the receiving channel. The foam material is filled inside the shaft to imitate the porous structure of natural feathers, so that the feather shaft can be light in weight and low in density, while maintaining impact resistance and toughness.

The technical problem to be solved by this new invention is to provide an artificial feather for badminton, which has the advantages of fast production, strong structure and reduced consumption of natural resources.

In order to solve the above technical problems, a preferred embodiment of the artificial feathers of the new badminton includes: a main shaft, a first feather groove, a first feather, and a second feather; the artificial feather is a micro-elastic porous structure with micro-bubbles made of a thermoplastic mixed material containing artificial fibers and then manufactured by micro-foaming injection molding technology; the composition of the thermoplastic mixed material containing artificial fibers includes: 80% to 90% by weight of nylon and 10% to 20% by weight of artificial fibers;

The first feather groove is located at least one of the top and back surfaces of the main axis, and the first feather groove extends along the axial direction of the main axis;

The first and second vanes are respectively arranged on the left and right sides of the rachis and connected to the rachis as a whole. The structures of the first and second vanes are symmetrical to each other. The first and second vanes include: a plurality of barbs that are parallel to each other and arranged at intervals, and there is a feather membrane between any two adjacent barbs. One end of the barbs is connected to the rachis, and the other end of the barbs extends in a direction away from the rachis. An inner side of the feather membrane is connected to the rachis.

The two axial ends of the main shaft are slightly curved toward the back direction to form a curved arc.

As a preferred embodiment of the artificial feathers of the new badminton, the width of the main shaft gradually narrows from the feather root to the feather shaft, and the thickness of the main shaft gradually thins from the feather root to the feather shaft.

As a preferred embodiment of the artificial feathers of the new badminton, the cross-sectional shape of the feather branches is arc-shaped or semicircular.

As a preferred embodiment of the artificial feathers of the new badminton, the thickness of the first feather and the second feather gradually decreases from the feather shaft toward the direction away from the feather shaft.
