Abstract

String silencers for reducing the sound made when an arrow is released from a bow. These silencers are made from a material which allows the silencer to freely flex when the arrow is released and the bow string begins to vibrate. Silencers usable with conventional bow strings and with split bow strings are disclosed. Disclosed silencers for conventional bow strings have uniform and necked down configurations, and a representative, disclosed silencer for split bow strings has a center segment and integral arms at opposite ends of the center segment. With the silencer at rest, these arms extend in opposite directions from, and at equal angles to, the center segment.

Claims

1. The combination of:

a bow;

a bow string; and

a silencer assembled to the bow string;

said silencer being a single elongated strip which is fabricated from an elastomeric material;

said silencer being so configured and related to the bow string that segments of the silencer can flex when an arrow is released and vibrations are consequentially set up in the bow string; and

there being a single overhand knot which is;

(a) tied in said silencer and around the entire circumference of the bow string, and (b) attaches the silencer to the bow string.

2. The combination of:

a bow;

a bow string; and

a silencer assembled to the bow string;

said silencer being fabricated from an elastomeric material;

said silencer being so configured and related to the bow string that segments of the silencer can flex when an arrow is released and vibrations are consequentially set up in the bow string;

the bow string being split into elements;

the silencer being installed between the elements of the bow string;

said silencer having a center segment and first and second arms;

said arms being integrated with the center segment at opposite ends of said segment; and

when said silencer is unstressed, said first and second arms extending in opposite directions from, and at equal angles to, said center segment.

3. The combination of:

a bow;

a bow string; and

a silencer assembled to the bow string;

said silencer being fabricated from an elastomeric material;

said silencer being so configured and related to the bow string that segments of the silencer can flex when an arrow is released and vibrations are consequentially set up in the bow string;

the bow string being split into elements and the silencer being installed between the elements of the bow string; and

there being complementary protrusions on opposite sides of the silencer for trapping the first and second bow string elements on opposite sides of the silencer and thereby securing the silencer between and to said elements.

4. The combination of:

a bow;

a bow string; and

a silencer assembled to the bow string;

said silencer being fabricated from an elastomeric material;

said silencer being so configured and related to the bow string that segments of the silencer can flex when an arrow is released and vibrations are consequentially set up in the bow string;

the string silencer being an elongated component with a generally rectangular cross section; and

the silencer having first and second end segments and a necked down center segment which is integrated, at opposite ends thereof, with said end segments.

5. The combination of:

a bow;

a bow string; and

a silencer assembled to the bow string;

said silencer being fabricated from an elastomeric material which is a viscoelastic mixture of choroprene and butyl polymers;

said silencer being so configured and related to the bow string that segments of the silencer can flex when an arrow is released and vibrations are consequentially set up in the bow string.

6. A combination as defined in claim 5 in which the string silencer is an elongated component with a generally rectangular cross section.

7. A combination as defined in claim 6 in which the cross-section of the string silencer is essentially the same throughout the length of the silencer.

8. A bow string silencer;

said silencer being fabricated from an elastomeric material and being so configured that, when attached to a bow string, segments of the silencer can wiggle and jiggle when an arrow is released to reduce the sound emanating from the bow string upon the release of said arrow;

said silencer having a center segment and first and second arms;

said arms being integrated with the center segment at opposite ends of said segment; and

when said silencer is unstressed, said first and second arms extending in opposite directions from, and at equal angles to, said center segment.

9. A bow string silencer;

said silencer being fabricated from an elastomeric material and being so configured that, when attached to a bow string, segments of the silencer can wiggle and jiggle when an arrow is released to reduce the sound emanating from the bow string upon the release of said arrow; and

there being complementary protrusions on opposite sides of the silencer for trapping said silencer between first and second bow string elements and thereby securing the silencer between and to said elements.

10. A bow string silencer;

said silencer being fabricated from an elastomeric material and being so configured that, when attached to a bow string, segments of the silencer can wiggle and jiggle when an arrow is released to reduce the sound emanating from the bow string upon the release of said arrow;

said silencer being an elongated, slit and aperture free component with a cross-section which is essentially the same throughout the length of the silencer; and

said silencer being so dimensioned and configured that it can be attached to a bow string by tying a single overhand knot in the silencer.

11. A bow string silencer;

said silencer being fabricated from an elastomeric material and being so configured that, when attached to a bow string, segments of the silencer can wiggle and jiggle when an arrow is released to reduce the sound emanating from the bow string upon the release of said arrow; and

said silencer having first and second end segments and a necked down center segment which is integral, at opposite ends thereof, with said end segments.

12. A bow string silencer;

said silencer being fabricated from an elastomeric material and being so configured that, when attached to a bow string, segments of the silencer can wiggle and jiggle when an arrow is released to reduce the sound emanating from the bow string upon the release of said arrow;

said silencer having a center segment and first and second arms;

said arms being integrated with the center segment at opposite ends of said segment;

said first and second arms extending in opposite directions from said center segment; and

said arms being so configured and related to said center segment that, in the moment after an arrow is released, said arms;

(a) are parallel, (b) at equal distances from, and on opposite sides of, an axis of symmetry through the bow and bowstring, and (c) trail the center segment of the silencer.
