Abstract

A rifle telescope has a scope body having an objective end and an eyepiece end. A front mount and a rear mount are spaced apart from each other and connected to the scope body. The front mount is connected more proximate to the objective end, and the rear mount is connected more proximate to the eyepiece. The scope body is axially fixed to the front mount while being pivotally connected to the front mount. The rear mount includes an adjustable suspension operable to establish a selected vertical and horizontal position of the scope body portion received within the rear mount. The scope body may include a ball portion that interacts with a socket portion of the front mount to provide pivoting, or may include a flange that is constrained by elastomeric rings on the front mount to provide pivoting, centering, and shock absorption. The rear mount may be split in two portions to open and permit removal of the scope body. An objective lens assembly may be slidably mounted at the objective end to absorb recoil forces.

Claims

1. A rifle telescope comprising:

a scope body having an objective end and an eyepiece end;

a front mount and a rear mount spaced apart from each other, each connected to the scope body, with the front mount connected more proximate to the objective end, and the rear mount connected more proximate to the eyepiece end;

the scope body being axially fixed to the front mount;

the scope body being pivotally connected to the front mount;

the rear mount including an adjustable suspension operable to establish a selected vertical and horizontal position of the scope body portion received within the rear mount the scope body including a ball portion received by the front mount;

the front mount having a socket portion for closely receiving the ball portion;

the socket portion including a pair of rings defining interior bores with diameters less than that of the ball portion, and wherein the rings are adjustably spaced to provide a selectable compression of the ball portion.

2. The rifle telescope of claim 1 wherein including an objective lens assembly connected at the objective end of the scope body, and suspended for axial reciprocation with respect to the scope body in response to an axial recoil force.

3. The rifle telescope of claim 2 including a recoil spring operably connected to the scope body and to the objective lens assembly.

4. The rifle telescope of claim 1 wherein the rear mount includes a first portion having a base mount portion operable to connect to a rifle, and a rigid second portion pivotally connected to the first portion for motion between a closed position in which the scope body is secured within a passage defined by the first and second portions, and an open position in which the scope body may be removed from the rear mount.

5. The rifle telescope of claim 4 wherein one of the first and second portions of the rear mount includes a spring element biased toward the axis of the scope body, and the other of the first and second portions of the rear mount includes a vertical adjustment screw and a horizontal adjustment screw, each having a contact point facing the axis of the scope body, such that the spring element biases the scope body against the contacts points when the rear mount is in the closed position.

6. The rifle telescope of claim 1 wherein the portion of the scope rearward of the front mount has a maximum outside diameter less than the diameter of an aperture defined by the front mount.

7. The rifle telescope of claim 1 wherein the scope body includes a lateral protrusion protruding laterally with respect to the scope body axis, the lateral protrusion received by the front mount, and wherein the front mount includes an elastomeric element forward of the protrusion, and an elastomeric element rearward of the protrusion.

8. The rifle telescope of claim 7 wherein the protrusion is a flange encircling the scope body, and the elastomeric element are rings.

9. The rifle telescope of claim 7 wherein the scope body includes a support surface adjacent to the protrusion and encircling the scope body, and the front mount includes an inner bore surface concentric with the support surface, and wherein at least one of the elastomeric elements is a ring compressibly received between the support surface and the inner bore surface.

10. The rifle telescope of claim 1 including an objective lens housing connected at the objective end and having a flat rearward facing surface having a selected diameter and imprinted with indicia, the front mount having an exterior profile smaller than the flat rearward surface, such that at least some of the indicia is visible from the rear end.

11. A rifle telescope comprising:

a scope body having an objective end and an eyepiece end;

a front mount and a rear mount spaced apart from each other, each connected to the scope body, with the front mount connected more proximate to the objective end, and the rear mount connected more proximate to the eyepiece end;

the scope body being pivotally connected to the front mount;

the rear mount including an adjustable suspension operable to establish a selected vertical and horizontal position of the scope body portion received within the rear mount; and

the rear mount including a first portion having a base mount portion operable to connect to a rifle, and a rigid second portion pivotally connected to the first portion for motion between a closed position in which the scope body is secured within a passage defined by the first and second portions, and an open position in which the scope body may be removed from the rear mount.

12. The rifle telescope of claim 11 wherein one of the first and second portions of the rear mount includes a spring element biased toward the axis of the scope body, and the other of the first and second portions of the rear mount includes a vertical adjustment screw and a horizontal adjustment screw, each having a contact point facing the axis of the scope body, such that the spring element biases the scope body against the contacts points when the rear mount is in the closed position.

13. A rifle telescope comprising:

a scope body having an objective end and an eyepiece end;

a front mount and a rear mount spaced apart from each other, each connected to the scope body, with the front mount connected more proximate to the objective end, and the rear mount connected more proximate to the eyepiece end;

the scope body being axially fixed to the front mount;

the scope body being pivotally connected to the front mount;

the rear mount including an adjustable suspension operable to establish a selected vertical and horizontal position of the scope body portion received within the rear mount; and

an objective lens assembly connected at the objective end of the scope body, and suspended for axial reciprocation with respect to the scope body in response to an axial recoil force.

14. The rifle telescope of claim 13 including a recoil spring operably connected to the scope body and to the objective lens assembly.

15. A rifle telescope comprising:

a scope body having an objective end and an eyepiece end;

a front mount and a rear mount spaced apart from each other, each connected to the scope body, with the front mount connected more proximate to the objective end, and the rear mount connected more proximate to the eyepiece end;

the scope body being axially fixed to the front mount;

the scope body being pivotally connected to the front mount;

the rear mount including an adjustable suspension operable to establish a selected vertical and horizontal position of the scope body portion received within the rear mount; and

wherein the scope body includes a lateral protrusion protruding laterally with respect to the scope body axis, the lateral protrusion received by the front mount, and wherein the front mount includes an elastomeric element forward of the protrusion, and an elastomeric element rearward of the protrusion.

16. The rifle telescope of claim 15 wherein the protrusion is a flange encircling the scope body, and the elastomeric element are rings.

17. The rifle telescope of claim 15 wherein the scope body includes a support surface adjacent to the protrusion and encircling the scope body, and the front mount includes an inner bore surface concentric with the support surface, and wherein at least one of the elastomeric elements is a ring compressibly received between the support surface and the inner bore surface.
