Abstract

A range finder adapted to be mounted to a scope. The range finder includes a main housing, range finding circuit received in the main housing and a mounting mechanism adapted to mount the main housing to a scope.

Claims

1. A range finder system comprising:

a main housing having a signal end and a display end opposite the signal end;

a range finder circuit contained in the main housing and adapted to project and receive signals through the signal end;

a display in electrical communication with the range finder circuit, the display attached to the main housing and adapted to display distances to objects determined by the range finder circuit;

a support plate having a mounting rail, the support plate attached to the main housing; and

at least one scope mount ring having a first end for receiving the mounting rail and a second, opposite end for surrounding a scope.

2. The range finder system of claim 1, wherein the support plate is mounted above the scope by the at least one scope mount ring.

3. The range finder system of claim 2, wherein the at least one scope mount ring comprises two spaced apart scope mount rings, a first scope mount ring located near the display end of the main housing and a second scope mount ring located near the signal end of the main housing.

4. The range finder system of claim 1, wherein the scope is mounted to a weapon.

5. The range finder system of claim 4, wherein the scope is mounted above the weapon.

6. The range finder system of claim 5, wherein the scope is mounted above the weapon by at least one scope mount ring.

7. The range finder system of claim 5, wherein the scope is mounted above the weapon by two spaced apart scope mount rings.

8. A range finder system comprising:

a main housing;

a range finder circuit located within the main housing;

a rail extending along a bottom of the main housing;

a scope located beneath the main housing; and

a first scope mount ring having a first end receiving the rail extending along the main housing and a second end surrounding the scope, thereby mounting the main housing above the scope.

9. The range finder system of claim 8, further comprising:

a second scope mount ring having a first end receiving the rail and a second end surrounding the scope, wherein the second scope mount ring is spaced apart from the first scope mount ring.

10. The range finder system of claim 9, further comprising:

a fourth scope mount ring having a first end receiving the rail extending along the weapon and a second end surrounding the scope, wherein the fourth scope mount ring is spaced apart from the third scope mount ring.

11. The range finder system of claim 8, further comprising:

a third scope mount ring having a first end receiving a rail extending along a weapon and a second end surrounding the scope, thereby mounting the scope above the weapon.

12. The range finder system of claim 8, wherein the first end of the first scope mount ring clamps the rail extending along the main housing.

13. A range finder system comprising:

a main housing having a signal end and a display end opposite the signal end;

a range finder circuit located within the main housing and adapted to project and receive signals through the signal end;

a first rail extending along a bottom of the main housing;

a scope located beneath the main housing;

a first set of spaced apart scope mount rings having first ends receiving the first rail extending along the main housing and second ends surrounding the scope, thereby mounting the main housing above the scope; and

a second set of spaced apart scope mount rings having first ends receiving a second rail extending along a weapon and second ends surrounding the scope, thereby mounting the scope above the weapon.
