Description
- This application claims priority to and the benefit of Korean Utility Model Application No. 20-2016-0003058 filed in the Korean Intellectual Property Office on Jun. 3, 2016, the entire contents of which are incorporated herein by reference.
- The present invention relates to the improved feathers of an arrow, and more particularly, to the improved feathers of an arrow, which prevent instability of flight caused by a vortex generated during the flight of the arrow by forming a plurality of arrow feathers attached to the arrow, which has a cross section which is a curved surface and integrally forming an auxiliary surface having one surface which is the curved surface with the arrow feather to guarantee stable flight.
- An arrow which is used for notching and shooting at a string of a bow, is constituted by an arrow shaft, an arrow pile, a fletching, and a nock. The arrow pile is mounted at the front end of the arrow shaft and the nock is mounted at the end of the arrow shaft for notching the string of the bow.
- In general, the arrow that leaves the string of the bow flies toward a target with a parabola and in this case, the arrow flies while swinging back and forth and left and right around the center of gravity of the arrow.
- In other words, the arrow does not fly straight toward the target, but flies while staggering as if the fish swims. Such a phenomenon is called a paradox phenomenon and the fletching serves to make the arrow fly straightly by air resistance by preventing the staggering.
- Further, the arrow flies while rotating by the air resistance applied to the fletching of the arrow and the rotating arrow flies more steadily than an unrotated arrow. That is, the arrow is stably moved by giving a slight pitch to the direction of the fletching mounted on the arrow shaft and such an effect is called a gyro effect.
- When the related art of the arrow is described, an arrow of Korean Patent Registration No. 10-1399544 (registration date: May 20, 2014) is characterized in that a diameter of a
shaft 110 in which apoint 120 is joined to a front end and a nock 140 is joined to a rear end is formed to decrease from the front end to the rear end to move the center of gravity in a front-end direction and control bending deformation, and theshaft 110 is divided into three parts, and a shaft front-end portion a is a portion joined with thepoint 120 and having a larger diameter to other portions, a shaft middle-end portion b extends from the shaft front-end portion a and has a diameter which becomes gradually smaller and smaller than the shaft front-end portion a, and a shaft rear-end portion c extends from the shaft middle-end portion b and constantly has the same diameter as a last portion of the shaft middle-end portion b. - Meanwhile, when a detailed configuration of arrow feathers constituting the arrow is described,
FIG. 1 is a perspective view of conventional general feathers of an arrow andFIG. 2 is a schematic view illustrating a connection type of the arrow and the arrow feathers as illustrated inFIGS. 1 and 2 . - The
conventional arrow feather 10 has anarrow pile 12 and anock 13 formed at both ends of anarrow shaft 11 and a plurality ofarrow feathers 14 are bonded to the surface of thearrow shaft 11 to be integrally formed at the front of thenock 13. - In addition, arrows users prevents occurrence of initial penetration resistance by wrapping a
tape 15 on an attachment portion of a front portion of thearrow feather 14 he tape in order to prevent occurrence of sensitive resistance in the process of flying the arrow. - However, when the tape is attached to prevent the initial penetration resistance as described above, problems such as an increase in weight of the arrow and the psychological weight of the user are caused.
- When the related art is described as an effort for solving the problem, a fletching for an arrow of Korean Patent Application Publication No. 10-2010-0132203 (publication date: Dec. 17, 2010) includes a frame 111 having the inside of an outer periphery is formed to be opened and forming an overall frame, multiple longitudinal rods 114 connecting the top and the bottom of the frame and disposed to be spaced apart from each other in the longitudinal direction of the frame, a
wing part 110 constituted by a thin film 112 formed in an empty space divided by the frame and the longitudinal rod, and aboded part 120 positioned on the bottom of the wing part and attached to an arrow shaft. - However, even in the process of the flight of the arrow feather having the above configuration, the vortex is generated due to a thin film formed between longitudinal rods, and as a result, the flight is not stable and an unstable phenomenon continuously occurs.
- The present invention is contrived by considering the situation and an object of the present invention is to provide the improved feathers of an arrow, which divides and derives a flow of air which influences the arrow feather while maintaining a predetermined shape in the process of flying an arrow to resolve initial penetration resistance generated at a connection portion of an arrow shaft and the arrow feather when the arrow flies and prevent a vortex generated if the air passes through the arrow feather, thereby remarkably increasing a flight safety, straightness, and a hit rate of the arrow.
- In particular, an object of the present invention is to provide the improved feather of an arrow, which can resolve a problem that a user feels a psychological weight without the need for a process such as taping a connection portion of the arrow shaft and the arrow feather in order for a user of the arrow to secure a flight safety of the arrow.
- The object of the present invention can be achieved by improved feathers of an arrow in which arrow head and a notch are formed at both ends of an arrow shaft and a plurality of arrow feathers are bonded to the surface of the arrow shaft to be integrally formed at the front of the notch, including: an
attachment surface 120 curved in a direction opposite to a curved direction of abody 110 and an auxiliary surfaced 130 curved in the same or similar shape as a curved shape of the body by separating a part of theinner surface body 110, which are integrally formed at a lower portion of thebody 110 curved in one direction. - The plurality of
auxiliary surfaces 130 is formed on the inner surface of thebody 110. - The
auxiliary surface 130 has a smooth flat plate shape. - The
attachment surface 120 is curved with the same arc as the surface of the arrow shaft to which thearrow feathers 100 are attached. - The improved arrow feather according to the present invention maintains a predetermined shape and a body is formed to be curved in one direction in the process of flying the arrow and in particular, the flow of the air which is applied to the arrow feather is divided and derived by a curved auxiliary surface in the body to prevent the vortex from being generated by the arrow feather when the arrow flies or the vortex is divided and distributed to improve the flight safety and the straightness, thereby remarkably increasing the hit rate.
- That is, the vortex generated by the arrow feather is resolved and the initial penetration resistance of air which flows into the arrow feather is decreased to induce stable flight.
- In particular, the user can resolve a psychological weight without the need for a process such as taping a connection portion of the arrow shaft and the arrow feather in order for the user of the arrow to secure the flight safety of the arrow.

- 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.
- 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.
- 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 ofFIG. 3 taken along line A-A, andFIGS. 6 to 8 are side views illustrating another embodiment of the improved arrow feather according to the present invention. - As illustrated, in the improved
arrow feather 100 according to the present invention, anattachment surface 120 that is bent from abody 110 and attached to the surface of anarrow shaft 11 is integrally formed at a lower portion of thebody 110 curved in one direction. - The
body 110 generally has a substantially rounded shape in one direction. - The
attachment surface 120 is configured to have the same arc as thearrow shaft 11 attached by bending the lower portion of thebody 110 in a direction opposite to the rounding direction of thebody 110. - That is, since the
attachment surface 120 has the same curved surface as the surface of thearrow shaft 11 in the process of attaching thearrow feathers 100 to thearrow shaft 10, thearrow feathers 100 may be completely in close contact with thearrow shaft 11 to minimize initial penetration resistance generated at a connection portion of thearrow shaft 11 and thearrow feathers 100 while the arrow flies. The reduction of the initial penetration resistance also reduces the central resistance generated at the center of thearrow feathers 100, thereby inducing a stable flow of air. Since thearrow shaft 11 and thearrow 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. - Meanwhile, the present applicant forms an
auxiliary surface 130 integrally formed with thebody 110 on the inner surface of thebody 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. - That is, the
auxiliary surface 130 is formed on a curved inside of the curved inner surface of thebody 110, and a part of the inner surface of thebody 110 is separated and bent in the same or similar shape as the curved shape of the body. - As illustrated in the
FIG. 9 , thebody 110 of thearrow 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. - 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 thebody 110 of thearrow feathers 100 and integrally forming theauxiliary surface 130 which protrudes on the inner surface of thebody 110. - In other words, as illustrated in the figure, the air introduced by the
auxiliary surface 130 is divided while colliding with theauxiliary 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. - Meanwhile, the
auxiliary surface 130 may be formed in various shapes and positions as shown inFIGS. 6 to 8 . - That is, as illustrated in
FIG. 6 , theauxiliary surface 130 may be formed on the top of thebody 110, as illustrated inFIG. 7 , a plurality of auxiliary surfaces may be configured, or as illustrated inFIG. 8 , theauxiliary surface 130 may be formed to have a flat plate shape without being curved. - The described auxiliary surface may be formed integrally with the
body 110 at various positions on the inner surface of thebody 110 in addition to the exemplified positions. - That is, the
arrow 10 flies while being rotated by thecurved body 110 of thearrow feathers 100 and in this case, the air flowing into the inside of thebody 110 is divided while colliding with theauxiliary surface 130 and the flow of the air is stably induced to prevent the generation of the vortex of the air flowing into thebody 110, thereby assuring the stable flight of the arrow. - 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.
