Arrow rest
An arrow rest arrangement in a capture style arrow rest for an archery bow. The arrow capture portion may be formed as an inverted brush. The arrow capture portion defines a central aperture through which an arrow shaft extends. The aperture may include two straight slanted lower side portions forming a “V” profile to support the arrow.
1. An arrow rest arrangement, comprising:
a frame portion adapted to be mounted to an archery bow;
an arrow capture portion in the frame portion to support an arrow shaft, the arrow capture portion being formed by a plurality of bristles extending inward to define an aperture for the arrow shaft;
wherein the aperture has two straight side portions intersecting at a lower point and diverging at an acute angle to form a “V” profile with a downward pointing apex wherein the two straight side portions are arranged so that two downward diverging vanes of an arrow pass through the bristles of the straight side portions upon release.
2. The arrow rest arrangement of claim 1 , wherein the downward pointing apex is in a vertical plane centered on the arrow shaft.
3. The arrow rest arrangement of claim 1 , wherein the two side portions are arranged to be tangential to an arrow shaft arranged through the aperture, wherein the side portions each engage and support the arrow shaft at a single point of contact.
4. The arrow rest arrangement of claim 3 , wherein the side portions are arranged to center arrows along a central vertical plane within the aperture.
5. The arrow rest arrangement of claim 3 , wherein the side portions are arranged to center arrows along a vertical plane centered between the single points of contact of the two side portions.
6. The arrow rest arrangement of claim 1 , wherein the aperture has an arcuate upper portion.
7. The arrow rest arrangement of claim 6 , wherein the arcuate upper portion spans approximately 180 degrees.
8. The arrow rest arrangement of claim 1 , wherein the aperture has a straight upper portion extending horizontally above the arrow.
9. An arrow rest arrangement, comprising:
an archery bow with upper and lower limbs extending to upper and lower limb tips and with a bowstring extending between the limb tips;
an arrow with an arrow shaft defining an axis perpendicular to the bowstring;
an arrow capture portion mounted to the archery bow to support the arrow shaft, wherein the arrow capture portion is mounted in a plane substantially perpendicular to the axis of the arrow shaft, the arrow capture portion define an aperture encircling the arrow shaft;
wherein the aperture includes two sets of bristles forming two straight side portions intersecting at a lower point and diverging at an acute angle, wherein the lower point at which the two side portions intersect is in a vertical plane centered on the arrow shaft and wherein the two straight side portions are tangential to the arrow shaft and each support the arrow shaft at a single point of contact;
wherein the two sets of bristles are arranged so that two downward diverging vanes of the arrow pass through the bristles of the two straight side portions upon release.
10. The arrow rest arrangement of claim 9 , wherein the aperture comprises a third set of bristles above the arrow shaft.
11. The arrow rest arrangement of claim 10 , wherein the third set of bristles is arcuately shaped.
12. The arrow rest arrangement of claim 10 , wherein the third set of bristles form a straight upper portion extending horizontally above the arrow.
13. The arrow rest arrangement of claim 9 , wherein the two straight side portions support the arrow shaft at contact points approximately 120 degrees apart.
14. An arrow rest arrangement, comprising:
a frame portion adapted to be mounted to an archery bow;
an arrow capture portion arranged in the frame portion to support an arrow shaft, the arrow capture portion defining an aperture encircling the arrow shaft; and
wherein the profile of the aperture defines an inverted teardrop shape with a closed continuous perimeter defined by two straight edges which intersect at a lower point and define a downward pointing corner, the profile further defined by an arcuate upper portion extending between upper ends of the straight edges.
15. The arrow rest arrangement of claim 14 , wherein the straight edges intersect at an angle of approximately 60 degrees.
16. The arrow rest arrangement of claim 14 , wherein the arrow capture portion includes two sets of bristles forming the two straight edges.
17. The arrow rest arrangement of claim 14 , wherein there are only two points of direct contact between the arrow shaft and the arrow capture portion when the arrow shaft is supported by the two straight edges.
18. The arrow rest arrangement of claim 17 , where the two points of direct contact are spaced approximately 120 degrees apart around the arrow shaft.
19. The arrow rest arrangement of claim 14 , wherein the two straight edges are arranged to center arrows along a central vertical plane within the aperture.
20. The arrow rest arrangement of claim 19 , wherein a single size of the two straight edges will center arrows with shaft diameters in a range between 4.0 mm and 10.7 mm.
