Abstract

An illuminated bowsight is disclosed which includes a light-emitting diode centrally located in a sighting ring and a battery to illuminate the diode. A switching device is provided on the bowsight to selectively connect and disconnect the battery to the light-emitting diode. The switching mechanism is arranged so that no additional wiring is required other than the two leads which are normally provided on a commercially available light-emitting diode.

Claims

1. An illuminated bowsight comprising:

a. a body member having a cavity defined therein;

b. mounting means attached to the body member for mounting the bowsight on the bow;

c. a circular sighting ring attached to the body member;

d. a battery received in the cavity in the body member; and

e. a light-emitting diode having two leads and mounted on the bowsight so as to be positioned in the center of the circle of the sighting ring with the leads being mechanically connected to the sighting ring to fasten the light-emitting diode in position, the light-emitting diode being electrically connected to the battery to provide a visible sighting mark in dim light.

2. An illuminated bowsight as claimed in claim 1 wherein the light-emitting diode has two leads, one of the leads being electrically and mechanically connected to the sighting ring, the other lead being electrically connectable to the battery.

3. An illuminated bowsight as claimed in claim 2 wherein the other lead of the light-emitting diode extends through a portion of the body member and is electrically insulated from the body member.

4. An illuminated bowsight as claimed in claim 3 wherein the other lead of the light-emitting diode is insulated from the body member by an insulating sleeve received over the other lead where it is received through the body member.

5. An illuminated bowsight as claimed in claim 2 wherein the other lead extends into the cavity in the body member to make electrical contact with the battery.

6. An illuminated bowsight as claimed in claim 5 further including a cap closing the end of the cavity and a compression spring disposed between the cap and the battery to urge the battery against the other lead of the light-emitting diode.

7. An illuminated bow sight as claimed in claim 1 wherein the sighting ring is sized so as to correspond to the apparent size of a desired target at a predetermined distance from the archer so that the sighting ring may be used as a range finder by the archer.

9. An illuminated bowsight as claimed in claim 7 wherein a sighting ring is attached to the body member and the light-emitting diode is centrally positioned in the sighting ring.

17. An illuminated bowsight as claimed in claim 7 wherein the mounting means is a threaded shaft extending from the body member.

8. An illuminated bowsight comprising:

a. a body member having a cavity defined therein;

b. mounting means attached to the body member for mounting the bowsight on a bow;

c. a battery received in the cavity in the body member;

d. a light-emitting diode extending from the body member so as to be positioned in the line of sight of the archer the light-emitting diode having two leads, one of which is electrically and mechanically connected to the body member and the other of which is selectively connected to the battery; and

e. a manually operated switch mounted in the body member for selectively connecting the battery to the other lead of the light-emitting diode to illuminate the light-emitting diode to serve as a sighting mark in dim light.

10. An illuminated bowsight as claimed in claim 8 wherein the other lead of the light-emitting diode extends through the body member into the cavity therein, and wherein an insulating sleeve received over the other lead electrically insulates the other lead from the body member.

11. An illuminated bowsight as claimed in claim 10 wherein an insulating sleeve surrounds the other lead of the light-emitting diode as it passes through the body member into the cavity.

12. An illuminated bowsight as claimed in claim 10 wherein the switch selectively connects the battery to the other lead of the light-emitting diode by selectively moving the battery into and out of contact with the other lead.

13. An illuminated bowsight as claimed in claim 11 wherein the switch includes a cam shaft extending through the body member, the cam shaft having a cam surface thereon so as to selectively allow contact between the battery and the other lead of the light-emitting diode.

14. An illuminated bowsight as claimed in claim 12 wherein the cam shaft has a channel formed in it extending about its periphery and wherein the other lead of the light-emitting diode is received in the channel so as to only contact the battery when the cam surface of the cam shaft is oriented toward the battery.

15. An illuminated bowsight as claimed in claim 12 wherein a switch wheel is connected to the cam shaft so that the cam shaft may be manually turned.

16. An illuminated bowsight as claimed in claim 11 wherein a cap is securely fastened in the cavity and wherein a compression spring is held between the cap and the battery to urge the battery against the cam shaft.
