Description

Feather shaft, feather blade having the feather shaft, and artificial badminton having the feather blade

The invention relates to an artificial badminton, in particular to an artificial badminton shaft and an artificial badminton having the artificial badminton shaft.

Please refer to FIG. 1, which is a kind of artificial feather and badminton disclosed in the patent case of "Badminton and its feather piece" of the Republic of China Announcement No. M539370. The patent case discloses a badminton 9 and its feather piece 91. Each of the feather pieces 91 has a feather shaft 92. One end of each feather shaft 92 is implanted in a ball head 93 made of soft wood and fixed with a bonding agent. Each of the feather shafts 92 is connected and fixed by a connecting line 94, so that the feather pieces 91 are fixed at equal intervals. The artificial badminton 9 can simulate badminton and reduce the badminton wear cost of players during training.

The artificial badminton 9 disclosed in the above patent case has a shaft 92 which can be made of plastic materials such as PP and PE by injection molding, or made of a carbon fiber shaft. Among them, the shaft 92 made of plastic materials such as PP and PE by injection molding is lighter and can meet the weight standard of badminton, but the strength of the shaft 92 is insufficient. After a limited number of hits with the racket, the shaft 92 will be broken and cannot be used any more.

In addition, in order to make the weight of the badminton meet the standard, the diameter of the badminton shaft 92 made of carbon fiber material is also limited. Therefore, the badminton shaft 92 made of carbon fiber material with a small diameter implanted in the ball head 93 will also fall off after a limited number of hits with the racket and cannot be used any more. In addition, the badminton shaft 92 with a small diameter made of carbon fiber material will bend and deform when hit by the racket, thereby affecting the flight direction of the artificial badminton 9 and affecting the training effect of the player.

In addition, no matter the badminton 92 is injection molded from plastic materials such as PP and PE, or is made of carbon fiber, the connecting line 94 for fixing the distance between the badmintons 92 will also form a sliding displacement, so that the distance between the badmintons 92 cannot be maintained, resulting in the flight direction of the artificial badminton 9 being offset, and the purpose of training cannot be achieved. In addition, the material loss of the artificial badminton 9 used for player training cannot be reduced, making the player training cost expensive.

In view of this, the conventional artificial badminton still needs to be improved.

To solve the above problems, the purpose of this invention is to provide a badminton shaft, which has better strength and the badminton made from the badminton shaft can meet the weight standard.

The second purpose of this invention is to provide a kind of feather, and this feather can be used to make artificial badminton.

Another purpose of the invention is to provide a badminton that can improve durability, reduce wear and tear of the badminton, and reduce the training costs of players.

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 badminton shaft of the invention comprises: a stem having a first end and a second end; and a covering layer covering the first end of the stem, wherein the cross section of the covering layer is formed into a non-circular shape, and the covering layer has an embedded section adjacent to the first end.

Accordingly, the badminton shaft of the invention is composed of the stem and the covering layer, so the badminton shaft has better strength and will not bend or deform.

The embedding section has at least one inverted groove, so that the first end of the stem and the coating layer can be firmly embedded in the ball head.

The first end of the stem is completely covered by the covering layer, or the proximal end of the first end is not completely covered by the covering layer and has an exposed section. In this way, the first end of the stem can be embedded in the ball head.

The cross section of the coating layer is formed into a hexagon, and the adjacent corners of the hexagon form arc angles. Thus, the arc angle can be firmly combined with the ball head and prevent the badminton shaft from falling off the ball.

The coating layer of the feather shaft of the invention further has at least one positioning groove, which is recessed on the surface of the coating layer. Thus, the positioning groove can be used for a connecting line to be inserted into the positioning groove to connect and fix the feathers, so that the connecting line can be firmly positioned without causing sliding displacement.

The positioning groove is located on a surface of the coating layer with a larger area. Thus, the positioning groove can be used for a connecting wire to be inserted into the positioning groove to connect and fix the plurality of feathers, so that the connecting wire can be positioned accurately without forming a sliding displacement effect.

The positioning grooves are located on two relatively large surfaces of the coating layer, so that a connecting line can be inserted into the two positioning grooves to connect and fix the plurality of vanes, so that the connecting line can be positioned accurately without causing sliding displacement.

The feather of the present invention comprises: the feather shaft mentioned above; and two pieces, each of which has a virtual center line, and the two pieces are located on the stem along the virtual center line and connected to the second end of the stem.

Accordingly, the feather shaft of the feather of the invention has better strength and will not bend or deform, so the artificial badminton made of the feather can ensure that the flying direction of the artificial badminton will not deviate.

The large-area surfaces of the two pieces correspond to the two relatively large-area surfaces of the covering layer. Thus, the covering layer can be firmly combined with the ball head and the badminton shaft will not fall off the ball.

The artificial badminton of the present invention comprises: the above-mentioned plurality of vanes; and a ball head, wherein the plurality of vanes are connected to the periphery of the ball head in a ring shape from the first end of each stem, and the first end of the stem and the embedded section of the covering layer are embedded in the ball head.

According to the invention, the artificial badminton has good strength and will not bend or deform, because the shaft is composed of the stem and the coating layer, so the flying direction of the artificial badminton can be ensured; and the embedded section on the shaft has at least one inverted groove, so the stem and the coating layer can be firmly combined with the ball head; and further, the positioning groove of the coating layer can be used to fix the ball head. A connecting line can be inserted to connect and fix the plurality of feathers. In this way, the connecting line can be accurately positioned without causing sliding displacement, so that the distance between the feathers can be maintained to ensure that the flying direction of the artificial badminton will not deviate, which can improve the training effect of the players; and the artificial badminton of this invention can be used for a long time, which can reduce the wear rate of the artificial badminton and the training cost.

The covering layer on each of the vanes has a larger surface facing the outer circumference or/and the center of the ball head, so that the body of each of the vanes can form a badminton.

The positioning groove of the coating layer on each of the vanes is oriented toward the outer circumference or/and the center of the ball head. Thus, a connecting line can be inserted into the positioning groove to connect and fix the vanes, so that the connecting line can be positioned accurately without causing sliding displacement.

The artificial badminton of the invention may further include a connecting line, which is inserted into the positioning groove on each of the feathers, and is used to connect and fix the feathers. In this way, the connecting line can be inserted into the positioning groove to connect and fix the feathers, so that the connecting line can be positioned accurately without causing sliding displacement.
