Abstract

A crossbow sighter is used to align the sight used on a crossbow to the axis of the groove on the crossbow. In this manner, the cross bow bolt will strike close to, or at, the location sighted by the sight. The crossbow sighter fits into the groove and has a body with a length that extends past the bow string when the bow string is in its fully relaxed position. The bow string rests against the body and applies cross-axial pressure to the crossbow sighter and helps retain it in the groove while aligning the crossbow sight.

Claims

1. A crossbow sighter for projecting a beam of light along the axis of a groove used to retain a crossbow bolt, the crossbow sighter comprising a body having a first end and a second end, with a length greater than the distance between the groove and the crossbow string when the crossbow string is in a relaxed position so that the first end is outside of the groove and past the relaxed crossbow string when the sighter is received in the groove, an outer surface dimensioned to be received in the groove, a power source at the first end, and a light source at the first end to emit a beam along the groove axis;

and

a switch positioned at the first end to selectively connect the power source to the light source.

2. The crossbow sighter of claim 1 wherein the body is cylindrical.

3. The crossbow sighter of claim 1 wherein the body diameter is uniform.

4. The crossbow sighter of claim 1 wherein the body includes a first cavity to house the light source, the switch, and the power source.

5. The crossbow sighter of claim 4 wherein the body includes an opening from which a beam of light from the light source is projected.

6. The crossbow sighter of claim 1 wherein the body includes a channel formed between the body surface and the first cavity to expose the switch.

7. The crossbow sighter of claim 6 wherein the switch is a partial cylinder, and wherein the switch is rotatable to selectively connect the power source to the light source.

8. The crossbow sighter of claim 7 wherein the switch includes a first outside surface radially disposed around a switch axis.

9. The crossbow sighter of claim 1 wherein the light source is a laser.

10. The crossbow sighter of claim 1 wherein the body is comprised of multiple sections.

11. The crossbow sighter of claim 1 wherein the body is formed of a single section.

12. The crossbow sighter of claim 1 wherein the body is comprised of one of the group consisting of:

aluminum, steel or plastic.

13. The crossbow sighter of claim 1 wherein the body has a length of at least 5″

, or at least 6″

, or at least 7″

.

14. The crossbow sighter of claim 1 wherein the body has a length between 6″

and 8″

.

15. The crossbow sighter of claim 1 wherein the body has a length of between 6½

″ and

7½

″

.
