Abstract
The invention encompasses firearm sights configured to eliminate the effect of parallax a shooter would otherwise experience when aiming a firearm at a target. The firearm sight utilizes a rear sight vane and at least one occluder positioned so that the occluder interferes with or substantially blocks a shooter's line of sight for the shooter's non-aiming eye without obstructing the vision of the correct eye with which the shooter should be aiming.
Claims20
A firearm sight, said firearm sight comprising:
- a. A sight frame capable of being mounted on a firearm, the sight frame comprising:
- a front end;
- a rear end, opposite the front end, the rear end of the sight frame to be positioned closer to a rear of the firearm than a front of the firearm when the sight frame is mounted on the firearm;
- a left sidewall;
- and
- a right sidewall, opposite the left sidewall, the left and right sidewalls extending from the rear end of the sight frame towards the front end of the sight frame;
- b. A rear sight vane at the front end of said sight frame, wherein an optical axis of sight passes between the left and right sidewalls and through the rear sight vane towards the front of the firearm;
- and
- c. An occluder at the front end of the sight frame and positioned so that said occluder interferes with or blocks a shooter's line of sight for the shooter's non-aiming eye without obstructing the vision of the correct eye with which the shooter should be aiming, wherein the occluder comprises:
- a left occluder portion on a left side of the optical axis of sight, the left occluder portion comprising:
- a first inner edge defining a left side of the rear sight vane;
- a first outer edge, opposite the first inner edge;
- and
- a left face between the first inner and outer edges, wherein the left face faces the rear end of the sight frame and extends outwards past the left sidewall in a first direction that is transverse to the optical axis of sight;
- and
- a right occluder portion on a right side of the optical axis of sight, opposite the left side of the optical axis of sight, the right occluder portion comprising:
- a second inner edge defining a right side of the rear sight vane, opposite the left side of the rear sight vane;
- a second outer edge, opposite the second inner edge;
- and
- a right face between the second inner and outer edges, wherein the right face faces the rear end of the sight frame and extends outwards past the right sidewall in a second direction that is transverse to the optical axis of sight and opposite the first direction.

A firearm sight, said firearm sight comprising:
- an occluder comprising a first occluder portion, and a second occluder portion, the first occluder portion comprising:
- a first inner edge;
- a first outer edge, opposite the first inner edge;
- and
- a first face between the first inner and outer edges;
- the second occluder portion comprising:
- a second inner edge;
- a second outer edge opposite the second inner edge;
- and
- a second face between the second inner and outer edges, wherein a gap formed between the first inner and second inner edges define a rear sight vane through which an optical axis of sight passes;
- a first sidewall extending away from the first face in a direction parallel to the optical axis of sight, the first sidewall comprising a first sidewall side surface that tapers down towards a first sidewall edge;
- and
- a second sidewall extending away from the second face in the direction parallel to the optical axis of sight, the second sidewall comprising a second sidewall side surface that tapers down towards a second sidewall edge, wherein a first width is between the first and second sidewall edges,
- a second width is between the first outer edge of the first occluder portion and the second outer edge of the second occluder portion, and
- wherein the second width is greater than the first width.

A firearm sight comprising:
- an occluder comprising first and second occluder portions, the first occluder portion comprising:
- a first inner edge;
- a first outer edge, opposite the first inner edge;
- a first face, between the first inner and outer edges;
- and
- a first top surface, coupled to the first face at an angle relative to the first face;
- the second occluder portion comprising:
- a second inner edge;
- a second outer edge, opposite the second inner edge;
- a second face, between second inner and outer edges;
- and
- a second top surface, coupled to the second face at an angle relative to the second face;
- a rear sight vane defined by a gap between the first inner edge of the first occluder portion and the second inner edge of the second occluder portion;
- a first sidewall extending from the first face in a direction parallel to a line of sight passing through the rear sight vane, the first sidewall comprising:
- a first sidewall side surface that tapers down towards a first sidewall edge;
- and
- a first sidewall top surface, coupled to the first sidewall side surface;
- a second sidewall extending from the second face in the direction parallel to the line of sight, the second sidewall comprising:
- a second sidewall side surface that tapers down towards a second sidewall edge;
- and
- a second sidewall top surface, coupled to the second sidewall side surface;
- a first flute, between the first and second sidewalls, the first flute extending from the first face of the first occluder portion in the direction parallel to the line of sight;
- a first optical fiber end on the first face of the first occluder portion and positioned between the first flute and the first sidewall;
- a second flute, between the first and second sidewalls, the second flute extending from the second face of the second occluder portion in the direction parallel to the line of sight;
- and
- a second optical fiber end on the second face of the second occluder portion and positioned between the second flute and the second sidewall, wherein a length of the first and second flutes is less than a length of the first and second sidewalls,
- wherein the line of sight passes through a gap between the first and second flutes,
- wherein the first top surface of the first occluder portion is higher than the first sidewall top surface,
- wherein the second top surface of the second occluder portion is higher than the second sidewall top surface,
- wherein a first width is between the first outer edge of the first occluder portion and the second outer edge of the second occluder portion,
- wherein a second width is between the first sidewall edge and the second sidewall edge, and
