Abstract

A scope adjustment system includes a turret cap assembly, a saddle assembly, and a quick spanner assembly. The turret cap assembly includes a ring with a plurality of regularly spaced apart teeth residing circumferentially around the ring. The saddle assembly includes a transportation element in mechanical communication with a plunger. The saddle assembly includes a click element to engage the teeth of the ring. The quick spanner assembly includes a bolt that may be coupled to the transportation element, a cam lock hinged to the bolt, and a pressure plate residing between the bolt and the cam lock. The bolt can be screwed into the transportation element, and the cam lock can be set to apply a force on the pressure plate such that the transportation element engages the plunger. When engaged, the plunger is responsive to rotations of the turret cap to adjust, e.g., an aiming reticle.

Claims

1. A scope comprising:

a tube;

an objective system;

an ocular system; and

an erector system comprising an adjustment mechanism connected to the tube such that the adjustment mechanism provides movement of a reticle on an image that is created by the objective system, the adjustment mechanism comprising a saddle mechanism, a turret cap mechanism, and a quick release mechanism, wherein the quick release mechanism comprises a threaded bolt, a lever, and a pressure plate, wherein the pressure plate resides between the threaded bolt and the lever, and wherein the lever is hingedly attached to the bolt.

2. The scope of claim 1, where the pressure plate is adjacent to the turret cap mechanism and applies pressure to the turret cap mechanism when the quick release mechanism is in the locked position.

3. The scope of claim 1, wherein the quick release mechanism is connected to the saddle mechanism.

4. The scope of claim 1, where the quick release mechanism further comprises a cam lock with an eccentric cam and an axle that locks the turret cap assembly such that the saddle assembly rotates when the cam lock is in a locked position and the turret cap is rotated.

5. The scope of claim 4, wherein the quick release mechanism can be unlocked using the lever.

6. The scope of claim 5, where the lever comprises a coin.

7. The scope of claim 5, where the lever comprises a rim of a cartridge.

8. The scope of claim 1, where the adjustment mechanism further comprises a tactile and/or audible click mechanism;

wherein the tactile and/or audible click mechanism comprises a first and a second plurality of click values corresponding to a predetermined shift in a position of a reticle of the scope; and

wherein the first plurality of click values has a different tactile response and/or audible response than the second plurality of click values.

9. The scope of claim 8, wherein the click mechanism further comprises:

a click ring having a first plurality of detents and a second plurality of detents with the first and second pluralities of detents corresponding to different tactile responses and/or audible responses; and

a click element engaging said detents.

10. The scope of claim 9, where the detents are grooves or ridges.

11. The scope of claim 9 further comprising at least two click rings wherein the first plurality of detents are on a different click ring from the second plurality of detents.

12. The scope of claim 11 further comprising at least two click elements wherein each click element engages a different click ring.

13. The scope of claim 9, where the click element comprises a detent ball.

14. The scope of claim 9, where the click element comprises a roughly wedge-shaped element designed to engage the detents of the click ring.

15. The scope of claim 9, where a single click element engages more than one click ring.

16. The scope of claim 1, where the turret cap mechanism is easily removable and replaceable by a second turret cap mechanism.

17. The scope of claim 16, where the turret cap mechanism has a different click value than the second turret cap mechanism.

18. The scope of claim 16, where the turret cap mechanism can be removed without tools.

19. The scope turret mechanism of claim 1, wherein the quick release mechanism further comprises a manually manipulatable component.
