## Abstract

An optical sight with a rectifier and device for indicating turns of the rectifier includes a longitudinal body that houses sight elements coupled to the rectifier. The rectifier includes a rotatable control element and an indicator protruding from an upper surface of the rectifier. The indicator includes a longitudinal identification protrusion rotatable about an axis that is perpendicular to its length and parallel to an axis of rotation of the control element. A coding device is associated with the longitudinal identification protrusion and is mounted on the upper surface of the rectifier above an upper surface of the longitudinal identification protrusion, wherein a rotated position of the longitudinal identification protrusion relative to the coding device provides an indication to a user of the optical sight of turning of the rectifier. A zero stop mechanism is configured with the control element of the rectifier.

## Claims

### Claim 1

An optical sight with a rectifier and device for indicating a turn of the rectifier, comprising:
a longitudinal body, wherein elements of the sight are mounted in the longitudinal body and operably coupled to the rectifier;
the rectifier comprising a manually rotatable control element and an indicator protruding from an upper surface of the rectifier, the indicator coupled to a mechanism configured to indicate a turn of the rectifier;
the indicator comprising a longitudinal identification protrusion having a length (L) in a direction along the upper surface of the rectifier, the longitudinal identification protrusion rotatable about an axis (OI) that is perpendicular to the length (L) and parallel to an axis (OP) of rotation of the control element, the longitudinal identification protrusion rotatable about the axis (OI) between a basic position and a turned position;
a coding device associated with the longitudinal identification protrusion and mounted on the upper surface of the rectifier above an upper surface of the longitudinal identification protrusion, wherein a rotated position of the longitudinal identification protrusion relative to the coding device provides to a user of the optical sight of turning of the rectifier; and
and a zero stop mechanism configured with the control element of the rectifier.

### Claim 2 (depends on 1)

The optical sight according to claim 1, wherein the coding device comprises a longitudinal strip disposed over the longitudinal identification protrusion.

### Claim 3 (depends on 1)

The optical sight according to claim 1, wherein the longitudinal identification protrusion rotates 90° between extreme rotated end positions.

### Claim 4 (depends on 1)

The optical sight according to claim 1, wherein the coding device comprises a shaped longitudinal strip disposed over the longitudinal identification protrusion and comprising a lower surface that follows the upper surface of the identification protrusion.

### Claim 5 (depends on 4)

The optical sight according to claim 4, wherein the coding device comprises a width corresponding to a width of the longitudinal identification protrusion.

### Claim 6 (depends on 1)

The optical sight according to claim 1, wherein the longitudinal identification protrusion comprises a color that is distinguishable from a color of the coding device.

### Claim 7 (depends on 1)

The optical sight according to claim 1, wherein the longitudinal identification protrusion and the control element of the rectifier are coupled to a Maltese cross gear mechanism that transmits rotation of the control element to the longitudinal identification protrusion.

### Claim 8 (depends on 7)

The optical sight according to claim 7, wherein the Maltese cross gear mechanism is rotatably mounted on a shaft having an axis of rotation identical to the axis of rotation (OI) of the longitudinal identification protrusion, the Maltese cross gear mechanism coupled to the longitudinal identification projection by a pin having one end eccentrically mounted in the Maltese cross gear mechanism and an opposite end eccentrically mounted in the longitudinal identification protrusion.

### Claim 9 (depends on 8)

The optical sight according to claim 8, wherein the Maltese cross gear mechanism is connected to the control element of the rectifier and comprises three grooves arranged in relative angular relation, the grooves engaging with a drive pin mounted on a housing of the rectifier.

### Claim 10 (depends on 1)

The optical sight according to claim 1, wherein the zero stop mechanism comprises a locking bolt mounted in the control element of the rectifier transversely to the axis (OP) of rotation of the control element, the locking bolt abutting a side wall of the rectifier in a locked position of the locking bolt.
