Abstract
An optic device turret for adjusting the optical element of the optic device. A spiral cam mechanism is engaged with the turret to define a maximum and minimum adjustment of the optical element. A rotation indicator displays the amount a knob has been rotated.
Claims16
A rifle scope comprising:
- a scope body;
- a moveable optical element defining an optical axis connected to the scope body;
- a turret having a screw defining a screw axis and operably connected to the optical element for changing the optical axis in response to rotation of the screw;
- a spiral cam mechanism commis* a stop element and connected to the screw and having a bushing configured to permit passage of the screw;
- the stop element defining a guide surface wrapping about the screw axis and terminating at first and second ends;
- a cylindrical body operable to engage the guide surface, and to engage the first and second ends, the engagement of the first and second ends defining rotational limits of the turret;
- wherein each of the first and second ends are at different radial distances from the screw axis.

A rifle scope with spiral cam mechanism comprising:
- a scope body;
- a moveable optical element defining an optical axis connected to the scope body;
- a turret having a screw operably connected to the moveable optical element for adjusting the optical axis in response to rotation of the screw;
- a spiral cam mechanism having a bushing configured to permit passage of the screw, the spiral cam mechanism defining a first stop surface positioned for engagement by a cylindrical body to limit rotation of the turret, such that the position at which the cylindrical body engages the first stop surface defines a zero position of the screw and the moveable optical element;
- the spiral cam mechanism defining a second stop surface positioned for engagement by a cylindrical body to limit rotation of the turret, such that the position at which the cylindfical body engages the second stop surface defines a maximum point of displacement of the screw and the moveable optical element;
- wherein the first stop surface and second stop surface are connected by a channel and further wherein the channel comprises a stepped spiral.

A rifle scope with spiral cam turret mechanism:
- a scope body;
- a movable optical element defining an optical axis connected to the scope body;
- an elevation turret having a screw operably connected to the movable optical element for adjusting the optical axis in response to rotation of the screw;
- the elevation turret having a knob operably connected to the screw to adjust the position of the screw;
- the elevation turret further having a bushing configured to permit passage of the screw;
- the elevation turret having a first stop surface positioned for engagement by an element to limit rotation of the elevation turret, such that the position at which the element engages the first stop surface defines a first limiting position of the screw and the movable optical element;
- the elevation turret further having a second stop surface positioned for engagement by the element to limit rotation of the elevation turret, such that the position at which the element engages the second stop surface defines a second limiting position of the screw and the moveable optical element;
- and wherein rotation of the screw causes the screw to move generally perpendicular to the optical axis.
