Description

Feather and badminton having the same

The invention relates to a feather and a badminton having the feather, in particular to an artificial feather and a badminton having a firm bond and capable of stable flight.

Please refer to FIG. 1, which is a kind of artificial feathers and badminton disclosed in the patent case of "Badminton and its feathers" of the Republic of China Announcement No. M539370. The patent case discloses a badminton 9 and its feathers 90. By setting a high wind resistance area 91 and a plurality of low wind resistance areas 92 on the feathers 90, the feathers 90 can provide different wind resistances during the travel of the badminton 9, so as to approach the hitting feeling of a natural badminton and the flight speed stability of a natural badminton.

The badminton 9 disclosed in the above patent case has a plurality of low-drag areas 92 formed as a plurality of circular holes or cutouts. However, since the adjacent feather pieces 90 are overlapped, the local low-drag area 92 of each feather piece 90 is covered by the high-drag area 91 of another adjacent feather piece 90. Thus, the covered low-drag area 92 cannot achieve the effect of reducing wind resistance. Moreover, since the covered low-drag areas 92 of each feather piece 90 are different, the plurality of feather pieces 90 cannot provide the same wind resistance during travel, thereby affecting the flight speed and stability of the badminton 9.

Please refer to FIG. 2, which is another artificial feather 80 and badminton 8 disclosed in the patent case of "simulated feathers and badminton for badminton" in China Publication No. CN202983112U, which includes a feather 80 and a feather stem 81. The feather 80 is formed by two elastic foam sheets bonded together, and two reinforcing layers 81 and 82 are arranged between the two foam sheets. Among them, the first reinforcing layer 81 is made of PET double-sided tape, and the second reinforcing layer 82 is made of a vertically long foam sheet.

Since the artificial feather disclosed in this patent case is bonded with PET double-sided tape (first reinforcement layer 81) between two vanes 80, the two vanes 80 cannot be firmly bonded, and After being struck several times, the two feather blades 80 will be separated or the edges will be raised, thereby affecting the flight speed and stability of the badminton 8 .

In view of this, the conventional feathers and badminton shuttlecocks having the feathers still need to be improved.

To solve the above problems, the purpose of the present invention is to provide a vane that can be firmly combined.

The second purpose of this invention is to provide a badminton that can provide low wind resistance so that the badminton can be close to the hitting feeling and stable flyer of a natural badminton.

The quantifiers "a" or "an" used in the elements and components described throughout this invention are only for convenience of use and to provide a general meaning of the scope of this invention; they should be interpreted in this invention as including one or at least one, and the concept of a single word also includes the plural case, unless it is obvious that it means otherwise.

The artificial feather of the invention comprises: a stem having a first end and a second end; and two sheets, each having a virtual center line, the two sheets are respectively welded to the stem by being located at the center line, and the two sheets are respectively provided with a number of low wind resistance portions on both sides of the center line.

Accordingly, the vanes of the present invention can be firmly combined because the stem of each vane and the two vane bodies are combined by welding.

The two pieces are symmetrical to each other on both sides of the center line. Thus, when the feathers are used to make a badminton, the badminton can be provided with a stable flying effect.

The low wind resistance part is a hole that penetrates the upper surface and the lower surface of each of the pieces. Thus, when the feather piece is used to make a badminton, the low wind resistance part can provide low wind resistance, so that the badminton can have an airflow pattern close to that of a natural badminton, and has a better hitting feeling and can fly stably.

The low wind resistance parts are formed on the two pieces respectively. Thus, when the feather piece is used to make a badminton, the low wind resistance parts can provide low wind resistance, so that the badminton can have an airflow pattern close to that of a natural badminton, and has a better hitting feeling and can fly stably.

The low wind resistance parts are formed after the two pieces are combined with the stem. Thus, when the feathers are used to make a badminton, the low wind resistance parts can provide low wind resistance, so that the badminton can have an airflow pattern close to that of a natural badminton, and have a better hitting feeling and a stable flying effect.

The low wind resistance parts are symmetrical to each other on both sides of the center line. Thus, when the feathers are used to make a badminton, the badminton can be provided with a stable flying effect.

The badminton of the present invention comprises: the above-mentioned plurality of feathers; and a ball head, wherein the plurality of feathers are connected to the ball head by the first end of each of the stems.

Accordingly, the badminton of the present invention has the same number of low wind resistance parts, and the low wind resistance parts are located on both sides of the center line in symmetry with each other. Therefore, when a badminton is made of the same number of the vanes, each of the vanes can provide the same low wind resistance, so that the badminton can have an airflow pattern close to that of a natural badminton, and has a better hitting feeling and a stable flying effect.

The low wind resistance parts of two adjacent feathers are staggered and uncovered. Thus, each feather can provide low wind resistance, so that the badminton can have an airflow pattern close to that of a natural badminton, and has a better hitting feeling and the effect of stable flight.

The low-drag portion is a half low-drag portion located at the edge of the blade, and the half low-drag portions of two adjacent feathers are relatively located to form a complete low-drag portion. In this way, the low-drag portion can make the badminton have an airflow pattern close to that of a natural badminton, and have a better hitting feeling and a stable flying effect.

The two adjacent sheets partially overlap in the horizontal direction, and the overlap size in the horizontal direction is not more than 3 mm. In this way, the badminton can have an airflow pattern close to that of a natural badminton, and has a better hitting feeling and a stable flying effect.

The two adjacent sheets do not have the low wind resistance portion at the overlapping portion, so that the badminton can have an airflow pattern close to that of a natural badminton, and has a better hitting feeling and a stable flying effect.

In order to make the above and other purposes, features and advantages of this creation more clearly understood, the following specifically cites a preferred embodiment of this creation and provides a detailed description in conjunction with the attached drawings; in addition, items marked with the same symbols in different drawings are deemed to be the same and their descriptions will be omitted.

Please refer to Figures 3 and 4, which are the vanes F of the first embodiment of the present invention, and are composed of a stem 1 and two plates 2, wherein the two plates 2 are combined at one end of the stem 1.
