Scope adjustment method and apparatus
View Patent ↗A rifle scope system allows adjustment of the scope while a shooter maintains the shooting posture and the scope sight picture. The scope system comprises an adjustment system comprising an electromechanical mechanism that responds to a signal from a remote controller manipulated by the shooter without having to significantly disturb the shooting posture. The adjustment system allows the shooter to adjust the scope's point of aim to coincide with a bullet's point of impact at a target. Such adjustment can be performed either by the shooter. Alternatively, such adjustment could be performed by a processor configured to adjust the point of aim based on a ballistic parameter associated with the bullet or the shooting environment. The adjustment system allows such processor-determined adjustments to be effected in a quick manner.
1. An adjustment mechanism device for an optical sighting apparatus, comprising:
a bolt adapted to move along a first direction wherein the bolt defines an engagement surface; and
an actuator adapted to move along a second direction wherein the actuator has a first end and a second end opposite to the first end and wherein the first end defines an angled surface that forms an angle with respect to the first direction and wherein the angled surface engages the engagement surface of the bolt such that the engagement surface pushing on the angled surface causes the actuator to move along the second direction;
wherein the movement of the actuator along the second direction causes the second end to engage and move a portion of an optical device along the second direction.
2. The device of claim 1 , wherein the engagement surface of the bolt pushing against the angled surface of the actuator along the first direction causes the actuator to move away from the bolt along the second direction such that the motion of the bolt by ΔX is transferred to the motion of the actuator by ΔY by a relationship approximated by ΔY=ΔX tan θ where θ represents the angle.
3. The device of claim 2 , wherein the portion of the optical device is biased such that when the bolt's engagement surface retracts from the angled surface, the actuator moves towards the bolt thereby allowing a reversible motion of the actuator.
4. The device of claim 3 , wherein the angle is between 0 and 45 degrees.
5. The device of claim 4 , wherein the bolt comprises a threaded bolt whose threads mate with threads formed on a housing about the bolt such that rotation of the threaded bolt causes it to move along the first direction.
6. The device of claim 5 , further comprising:
a dial indicator coupled to the threaded bolt such that the dial indicator rotates in response to the rotation of the threaded bolt, the dial indicator comprising indicator marks that indicate the movement of the portion of the optical sighting apparatus in response to the movement of the threaded bolt.
