Abstract
Arrow rest for archery bow is disclosed. The arrow rest is supported at a position remote from the sight window defining wall of the bow and extends obliquely towards the back of the bow with the free end thereof being located close to the sight window defining wall. Bias of the arrow from the correct advancing course at release is effectively restrained and resistance of the arrow rest acting on the arrow at release is greatly minimized, thereby assuring stable and smooth release of the arrow.
Claims4
An archery bow for use with an arrow of the type which includes a cylindrical shaft having a nock formed on one end thereof and a plurality of fletchings spaced 120.degree. apart about the periphery of said shaft, said archery bow comprising:
- (a) an archery bow having a sight window formed therein, said sight window including a generally horizontal bottom wall and a generally vertical side wall;
- and
- (b) an improved arrow rest, comprising:
- (1) an elongated body having a free end and being flexible in a direction parallel to said generally horizontal bottom wall;
- (2) support means coupled to said elongated body at a point spaced from said free end;
- said support means supporting said elongated body along a line extending between a first point and a second point forward of, and closer to said side wall than, said first point;
- said second point defining said free end of said elongated body and being sufficiently close to said side wall to ensure that when said arrow is shot by said bow with a first one of said fletchings oriented substantially perpendicular to said side wall and the remaining said fletchings contacting said side wall, a second fletching of said arrow contacts said elongated body and is biased, along with said nock, towards said side wall by the combined effect of said elongated body and said support means;
- said elongated body having a scooped portion therein extending from said free end towards the other end of said elongated body, said scoop portion limiting the distance which said arrow shot by said bow can move away from said generally vertical side wall.

- said support means for supporting said elongated body along a line extending between a first point and a second point forward of, and closer to said side wall than, said first point;
- said support means and said elongated body cooperating to bias said elongated body towards said side wall but permitting movement of said body away from said side wall in response to the application of an external force on said body;
- said second point defining said free end of said elongated body and being sufficiently close to said side wall to ensure that when said arrow is shot by said bow with a first one of said fletchings oriented substantially perpendicular to said side wall and the remaining said fletchings contacting said side wall, one of said remaining fletchings of said arrow contacts said elongated body and is biased, along with said nock, towards said side wall by the combined effect of said elongated body and said support means;
- said elongated body having a scooped portion extending from said free end towards the other end of said elongated body, said scooped portion limiting the distance which said arrow shot by said bow can move away from said generally vertical side wall when said arrow is shot by said bow.
