Abstract

Rifle scopes with friction reducing elements include a scope body, a movable optical adjustment element connected to the scope body, and a turret rotatably connected to the scope body. The turret includes a contact element contacting the adjustment element at a location of contact. The contact element is rotatable with respect to the turret. The adjustment element at the location of contact differs in hardness from the hardness of a second portion of the adjustment element. The contact element at the location of contact and the adjustment element at the location of contact are of essentially equal hardness.

Claims

1. A rifle scope comprising:

a scope body;

a movable reinforcing ring connected to the scope body;

a turret rotatably connected to the scope body;

the turret including a friction reducing element contacting the reinforcing ring at a location of contact, wherein the friction reducing element differs in hardness from the hardness of a portion of the turret to which the friction reducing element is attached; and

the friction reducing element being rotatable with respect to the turret.

2. The rifle scope of claim 1, wherein the friction reducing element has a flat surface that engages a portion of the turret to which the friction reducing element is attached.

3. The rifle scope of claim 1, wherein the friction reducing element has a flat surface that faces away from the turret.

4. The rifle scope of claim 1, wherein the reinforcing ring has a cylindrical exterior surface at the location of contact.

5. The rifle scope of claim 1, further comprising:

the reinforcing ring at the location of contact differing in hardness from the hardness of an erector tube encircled by the reinforcing ring; and

the friction reducing element at the location of contact and the reinforcing ring at the location of contact being of essentially equal hardness.

6. The rifle scope of claim 5, wherein the friction reducing element in its entirety is of essentially equal hardness to the hardness of the reinforcing ring at the location of contact.

7. The rifle scope of claim 1, wherein the friction reducing element and a portion of the turret to which the friction reducing element is attached are of essentially equal hardness.

8. The rifle scope of claim 1, wherein a portion of the friction reducing element that is attached to the turret and a portion of the turret to which the friction reducing element is attached are of essentially equal hardness.

9. A rifle scope comprising:

a scope body;

a movable reinforcing ring connected to the scope body;

a turret rotatably connected to the scope body;

the turret including a friction reducing element;

the friction reducing element having a contact surface facing away from the turret;

the friction reducing element having a contact surface facing towards the turret;

the contact surface facing away from the turret contacting the reinforcing ring at a location of contact, wherein the contact surface facing towards the turret differs in hardness from the hardness of a portion of the turret to which the friction reducing element is attached; and

the contact surface facing towards the turret being rotatable with respect to the turret.

10. The rifle scope of claim 9, further comprising:

the reinforcing ring at the location of contact differing in hardness from the hardness of an erector tube encircled by the reinforcing ring; and

the friction reducing element at, the location of contact and the adjustment element at the location of contact being of essentially equal hardness.

11. The rifle scope of claim 9, wherein the contact surface facing towards the turret and the contact surface facing away from the turret are of essentially equal hardness.

12. A rifle scope comprising:

a scope body;

a movable reinforcing ring connected to the scope body;

a turret rotatably connected to the scope body;

the turret including a friction reducing element;

the friction reducing element comprising an upper annular surface contacting the turret;

the friction reducing element comprising a lower cylindrical surface facing away from the turret;

the lower cylindrical surface contacting the reinforcing ring at a location of contact, wherein the upper annular surface differs in hardness from the hardness of a portion of the turret with which the upper annular surface is in contact; and

the upper annular surface being rotatable with respect to the turret.

13. The rifle scope of claim 12, further comprising:

the lower cylindrical surface at the location of contact differing in hardness from the hardness of an erector tube encircled by the reinforcing ring; and

the lower cylindrical surface at the location of contact and the friction reducing element at the location of contact being of essentially equal hardness.

14. The rifle scope of claim 12, wherein the upper annular surface and the lower cylindrical surface are of essentially equal hardness.
