With reference now to the drawings, and in particular to FIGS. 1 to 6 thereof, a new and improved hunting scope adjunct lens apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

More specifically, the hunting scope adjunct lens apparatus 10 of the instant invention essentially comprises mounting to a hunting scope 11 that is of itself of conventional construction of a type as exemplified and indicated in the U.S. Pat. No. 3,492,733 incorporated herein by reference.

Briefly, the hunting scope 11 includes an elongated tubular housing 11A having opposite front and rear ends (only the front end 11B being shown) and optical means contained in the tubular housing 11A for producing a first predetermined magnification of an object viewed through the optical means. As is well-known in the art and disclosed in aforementioned U.S. Pat. No. 3,492,733, the optical means includes an objective 11C disposed at the front end 11B of the housing 11A and an eyepiece (not shown) disposed at the rear end (not shown) of the housing 11A.

A cylindrical housing ring 12 is provided, having a support boss 13 positioned radially and exteriorly of the housing ring 12. A lens 14 is arranged and mounted within the housing ring 12 in a concentric relationship, wherein the lens 14 is of a typical magnification lens construction of any desired magnification as required. A scope securement skirt 15 extends from the lens 14 to the ring entrance 16, with the housing ring 12 formed of a resilient material arranged to permit resilient engaging of the forward end of a hunting scope received within the securement skirt 15, in a manner as indicated in FIG. 6.

More particularly, the housing ring 12 of the hunting scope adjunct lens apparatus or magnification lens accessory 10 has an annular body 12A defining a central opening 12B through the ring 12 and a front annular lip 12C defined on the annular body 12A at a front end of the ring 12 and projecting radially inwardly from the annular body 12A. The annular body 12A has an internal annular surface 12D thereon extending from the annular lip 12A to a rear end of the ring 12. The internal annular surface 12D has an internal diameter greater than the internal diameter of the annular lip 12C such that an annular radial shoulder 12E is formed by a rearward end of the annular lip 12C which is disposed adjacent to a forward end of the annular surface 12D and faces toward the rear end of the ring 12.

The magnifying lens 14 has opposite front and rear faces 14A, 14B and is received across the central opening 12B through the housing ring 12. The magnifying lens 14 has an outer annular edge 14C extending between the faces 14A, 14B which is mounted in a tight fitting relationship within the internal annular surface 12D on the annular body 12A thereof. Preferably, the magnifying lens 14 is disposed adjacent to the front annular lip 12C on the annular body 12A with the front face 14A of the magnifying lens 14 in abutting relation with the annular radial shoulder 12E and the rear face 14B of the magnifying lens 14 spaced from the rear end of the housing ring 12 so as to define the securement skirt 15 on the housing ring 12 adapting the ring 12 to removably fit and mount over the front end 11B of the tubular housing 11A of the hunting scope 11. The magnifying lens 14 of the accessory 10 is constructed to produce a second predetermined magnification of an object viewed through the magnifying lens 14 such that when the accessory 10 is applied to the hunting scope 11, the second predetermined magnification of the magnifying lens 14 will combine with the first predetermined magnification of the optical means of the hunting scope 11 to thereby increase and enhance the overall magnification of a distant object viewed through the hunting scope 11.

Additionally to secure the housing ring, a support tube 17 is provided having respective first and second telescoping legs 18 and 19 respectively extending from the support tube and the first telescoping leg respectively, such that the second telescoping leg 19 terminates in a bifurcated mount 20 having a first axle 21 pivotally mounting the bifurcated mount 20 to the support boss 13. A resilient split clamp ring 22 is arranged for securement about the body of the scope 11, wherein the clamp ring 22 includes a clamp ring boss 23, wherein a second axle 24 pivotally mounts a connecting rod 25 to the clamp ring boss 23. The connecting rod 25 is mounted to the support tube 17 about a third axle 26.

The FIGS. 5 and 6 indicate the use of a plurality of spring clips 27 radially oriented about the housing ring front wall 28 of the housing ring 12 arranged to secure accessory light filter lens 29 between the spring clips 27 and the lens 14 upon lifting of the spring clips 27 permitting the filter lens 29 to interfit between the spring clips 27 and the lens 14.

As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
