Riflescope with data display in field of view
First Claim
1. In a riflescope for sighting a firearm on a target and having an ocular lens with a field of view which includes a focal plane on which a target image can be formed, the improvement comprising an adjustable rangefinder control mounted on the riflescope and having a range scale of figures indicative of target distance, the scale being physically outside the ocular-lens view field to avoid interference with and reduction of the view field, and a scale-viewing optical system mounted on the riflescope and arranged to transmit light from the scale into the ocular-lens field of view to provide an image of a range-scale figure, the figure image being viewable through the ocular lens with the target image and being positioned in only a portion of an annular zone adjacent the periphery of the view field, substantially all of the remainder of the annular zone providing an unobstructed view of the target and surrounding area.

Abstract
A riflescope is provided with an auxiliary optical system for forming an internal image of data or information disposed outside of the normal eyepiece field of view. A primary application of the system is to transfer an optical image of a target-range figure marked on an external adjustment knob for viewing at the periphery of the field of view without interference with or cluttering of the target image.

6. In a riflescope having a mounting system supporting ocular, objective and erecting lenses on an optical axis, a rangefinding reticle at a focal plane of the ocular lens, and a power change adjustment for varying magnification of a target image in a field of view at the focal plane, the power change adjustment controlling position of a range scale of figures indicative of target distance, the scale being outside and unobstructive of the field of view, the improvement comprising:
an optical periscope supported on the mounting system and having a first end positioned adjacent the range scale, a second end positioned within the mounting system in the field of view and facing the ocular lens, and an intermediate portion extending generally radially of the optical axis between the first and second ends, whereby an image of a figure on the range scale can be viewed in the riflescope field of view, the periscope second end being positioned in only a portion of an annular zone of the field of view, the remainder of the annular zone providing a substantially unobstructed view of the target and surrounding area. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A riflescope comprising:
-
a generally tubular mounting means; an optical system supported on the mounting means and including spaced-apart ocular and objective lenses and an image-erecting system disposed in an enclosed space between the ocular and objective lenses; and a unitary light-transmitting periscope supported on the mounting means and having a first end which is external to the enclosed space and oriented to view a selected object external to the enclosed space, the periscope further having a second end positioned within the enclosed space between the ocular lens and image-erecting system for forming an image of the object which can be viewed through the ocular lens. - View Dependent Claims (14, 15, 16, 17, 18)
