Abstract

An arrow shaft includes an arrow shaft body, a plurality of first fletching indication patterns formed with extending to the longitudinal direction of the arrow shaft body on the outer circumferential surface of the arrow shaft body and spaced apart each other in the circumferential direction of the arrow shaft body, and a plurality of second fletching indication patterns formed in a direction of intersecting with the first fletching indication patterns and spaced apart each other in the circumferential direction of the arrow shaft body. The arrow shaft provides an accurate and easy fletching thanks to fletching indication patterns formed on the outer circumferential surface of the arrow shaft body, and also provides an easy aligning of fletchings to any position of the arrow shaft body with the fletching indication patterns depending on characteristics of users.

Claims

1. A cylindrical arrow shaft, comprising:

an arrow shaft body;

a plurality of first fletching indication patterns formed in accordance with a longitudinal direction of the arrow shaft body on an outer circumferential surface of the arrow shaft body and spaced apart from each other in a circumferential direction of the arrow shaft body; and

a plurality of second fletching indication patterns formed in a direction of intersecting with the first fletching indication patterns and spaced apart from each other in the longitudinal direction of the first fletching indication patterns.

2. The arrow shaft of claim 1, wherein the first fletching indication patterns are formed in a direction in parallel to the central axis line of the arrow shaft body, and the second fletching indication patterns are crossed vertically with the first fletching indication patterns.

3. The arrow shaft of claim 1, wherein the first fletching indication patterns are formed to have a pitch angle to the central axis line of the arrow shaft body, and the second fletching indication patterns are crossed vertically with the first fletching indication patterns.

4. The arrow shaft of claim 1, wherein the second fletching indication patterns are formed to be continued to the circumferential direction of the arrow shaft body.
