MODE FOR INVENTION

[0030] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0031] An embodiment to be described below is intended to be described in detail to enable those skilled in the art to easily carry out the invention and it is not meant that the technical spirit and scope of the present invention are limited thereto.

[0032] In addition, the size and shape of the components illustrated in the drawings may be enlarged for clarity and convenience of description, and terms particularly defined in consideration of a configuration and an operation of the present invention may vary depending on the intention or custom of a user or an operator and it should be noted that the definitions of the terms should be made based on contents throughout the present specification.

[0033] Among the accompanying drawings, FIG. 3 is a perspective view of a state in which an improved arrow feather is attached to an arrow shaft according to the present invention, FIG. 4 is a side view of the state in which the improved arrow feather is attached to the arrow shaft according to the present invention, FIG. 5 is a cross-sectional view of FIG. 3 taken along line A-A, and FIGS. 6 to 8 are side views illustrating another embodiment of the improved arrow feather according to the present invention.

[0034] As illustrated, in the improved arrow feather 100 according to the present invention, an attachment surface 120 that is bent from a body 110 and attached to the surface of an arrow shaft 11 is integrally formed at a lower portion of the body 110 curved in one direction.

[0035] The body 110 generally has a substantially rounded shape in one direction.

[0036] The attachment surface 120 is configured to have the same arc as the arrow shaft 11 attached by bending the lower portion of the body 110 in a direction opposite to the rounding direction of the body 110.

[0037] That is, since the attachment surface 120 has the same curved surface as the surface of the arrow shaft 11 in the process of attaching the arrow feathers 100 to the arrow shaft 10, the arrow feathers 100 may be completely in close contact with the arrow shaft 11 to minimize initial penetration resistance generated at a connection portion of the arrow shaft 11 and the arrow feathers 100 while the arrow flies. The reduction of the initial penetration resistance also reduces the central resistance generated at the center of the arrow feathers 100, thereby inducing a stable flow of air. Since the arrow shaft 11 and the arrow feathers 100 are closely contacted with each other, the initial penetration resistance is reduced and taping of the connecting portion is unnecessary, thereby eliminating a psychological weight increase factor of a user.

[0038] Meanwhile, the present applicant forms an auxiliary surface 130 integrally formed with the body 110 on the inner surface of the body 110 in order to stably enhance flyability by resolving a vortex generated during flying of the arrow feathers configured as above to remove and dividedly distribute the vortex generated on the inner surface of the arrow feathers while the arrow flies, thereby enhancing flight straightness.

[0039] That is, the auxiliary surface 130 is formed on a curved inside of the curved inner surface of the body 110, and a part of the inner surface of the body 110 is separated and bent in the same or similar shape as the curved shape of the body.

[0040] As illustrated in the FIG. 9, the body 110 of the arrow feathers 100 is curved to induce the arrow to rotate during flight, thereby improving the flight straightness. However, the vortex is generated in the air passing through the curved inner portion of the arrow feathers and the straightness of the arrow is not uniform due to swinging due to the vortex during the flight of the arrow, and the same problem may not be ensured due to the speed of flight and factors of a surrounding environment.

[0041] The present applicant enhances the flight safety and the straightness of the arrow by separating a part of the auxiliary surface 130 on the curved inner surface of the body 110 of the arrow feathers 100 and integrally forming the auxiliary surface 130 which protrudes on the inner surface of the body 110.

[0042] In other words, as illustrated in the figure, the air introduced by the auxiliary surface 130 is divided while colliding with the auxiliary surface 130 from the entrance portion before the vortex of the air is generated in the process of passing through the curved inner portion of the arrow feathers to prevent the vortex from being generated and the air passing through the inside of the arrow feathers is uniformly passed to stabilize the flight of the arrow and enhance the straightness, thereby remarkably increasing the hit rate.

[0043] Meanwhile, the auxiliary surface 130 may be formed in various shapes and positions as shown in FIGS. 6 to 8.

[0044] That is, as illustrated in FIG. 6, the auxiliary surface 130 may be formed on the top of the body 110, as illustrated in FIG. 7, a plurality of auxiliary surfaces may be configured, or as illustrated in FIG. 8, the auxiliary surface 130 may be formed to have a flat plate shape without being curved.

[0045] The described auxiliary surface may be formed integrally with the body 110 at various positions on the inner surface of the body 110 in addition to the exemplified positions.

[0046] That is, the arrow 10 flies while being rotated by the curved body 110 of the arrow feathers 100 and in this case, the air flowing into the inside of the body 110 is divided while colliding with the auxiliary surface 130 and the flow of the air is stably induced to prevent the generation of the vortex of the air flowing into the body 110, thereby assuring the stable flight of the arrow.

[0047] Although the present invention has been described in association with the aforementioned preferred embodiment, it can be easily recognized by those skilled in the art that various modifications and changes can be made without departing from the gist and the scope of the present invention and it is apparent that the changes and modifications are all included in the appended claims.
