Vane for an arrow, and an arrow exhibiting vanes
First Claim
1. A vane for guiding and stabilizing flight of an arrow through air after being released from a bow or crossbow provided with a string, the string of which bow or crossbow, at the time of release, is in engagement with a rear end of the arrow, said vane having an elongated and substantially planar body comprising:
- a foot having a sufficient transversal width to provide a base for mounting of the vane on an arrow shaft, such that said elongated body has a longitudinal extension in an axial direction of the arrow shaft;
a plurality of outer vane portions extending radially in a plane of said elongated body; and
an inner vane portion connecting the foot and said outer vane portions,wherein, between two neighboring outer vane portions, a respective valley, having a rounded shape at the bottom thereof, is formed by said two neighboring outer vane portions and the inner vane portion, with plural said valleys being formed between respective neighboring outer vane portions;
wherein a bottom of a deepest one of said valleys is located at a height of 17-30% of a total height of the vane;
wherein there are at least three outer vane portions defining respective peaks that progressively increase in height and then progressively decrease in height going from front to rear; and
wherein a natural bending joint for the outer vane portions in relation to the foot is provided in an area just above the bottom of the valleys.

Abstract
The present invention relates to fletching or vanes for arrows in archery and crossbow shooting, guiding the flight of the arrow through the air after the release, i.e. when the archer has released the arrow, and the arrow has left the string, and more particularly to a fletching or vane for quick stabilization of the flight of an arrow immediately after the release at instances of interference of the arrow with the bow, as well as an arrow fletched with such vanes.
