DETAILED DESCRIPTION OF THE INVENTION

Figure 1 is a full front view of a semicircular lens 1 of this invention, which is the preferred configuration herein. Shown therein for purposes of clarification and orientation is the left semi-circular edge 2, which has two attachment slots 22 for attachment of the lens 1 to a range finder sight (described infra) using an attachment means also described infra. The use of the word "left" herein is only for purposes of orientation, as there is contemplated within the scope of this invention a lens that has a mirror image of that shown in Figure 1, one being for right-handed archery shooters and the other being for left-handed archery shooters. The lens can be formed from any clear material, that is, visually clear material such as plastic or glass, or the like. The lens can actually be cut from such materials, or can be formed from such materials, such as by extruding, casting, molding, or the like. Preferred is an extruded plastic material.

Formed near the vertical center point P of the semi-circular lens 1 is the range finding capability of the lens 1, generally denoted as 50. The range finding capability 50 is configured such that there is a first horizontal line 3 that forms the base line for the range finding capability 50 located towards the bottom 5 of the semi-circular lens 1. Thereafter, there is a series of interconnected horizontal and vertical lines that make up a step-wise configuration. For example, first vertical line 4 is connected to the internal termination point 6 of the first horizontal line 3 and the top 7 the first vertical line 4. Thereafter, a second horizontal line 8 is connected to the top 7 of the first vertical line 4, a second vertical line 9 is connected to the second horizontal line 8 at the end 10, opposite of the end 7.

Further, vertical line 9 is connected at end 10 and connects at point 11 with a third horizontal line 12. The horizontal line 12 connects at point 13 with a third vertical line 14 and vertical line 14 connects at point 15 with a fourth horizontal line 16. Fourth horizontal line 16 then terminates at point 17. Thereafter, the vertical line 18 completes the leading edge of the lens 1.

It should be understood that the vertical and horizontal lines of the range finding capability 50 are predetermined such that the line 4 is longer than line 9 that is longer than line 14 and in this manner, using the bottom line 3 as a reference point, it can be determined how far away the target is from the shooter.

It is contemplated within the scope of this invention to provide all horizontal lines in the lens with bevel cuts, dyed, or painted lines in order to make such lines stand out from the lens per se. The bevel cuts provide a prism effect. As mentioned, the partial window 70 formed by the lines 3, 4, and 8 has the widest view, that is when the bottom line 3 is placed on the bottom belly line of the intended target, the line 8 will fall on the top back line of the target if the target is 10 yards away from the shooter.

Likewise, lines 3, 9 and 12 form a second partial window 80 in which the vertical line 9 is shorter than the vertical line 4 and when the shooter places the bottom line 3 on the bottom belly line of the target, and line 12 falls on the top back line of the target, this denotes a target that is about 20 yards from the shooter.

Still further, the line 3, 14 and 16 form a third partial window 90 in which the vertical line 14 is shorter than the line 9 and when the shooter places the bottom line 3 on the bottom belly line of the target, and line 16 falls on the top back line of the target, this denotes a target that is about 30 yards from the shooter.

It is contemplated within the scope of this invention that the lens 1 can have a fourth and a fifth level to show yardages of 40 and 50 yards. It is also contemplated within the scope of this invention that these yardages can be predetermined and the lens 1 so manufactured that they encompass a range of from about 5 yards to about 70 years by adjusting the partial window sizes relative to the bottom line 3. Although, distances to target game are usually handled in yards, it is contemplated within the scope of this invention to use feet in lieu of yards. In Figure 2, the yardage is denoted and marked directly on the lens 1, for example 20 yards, 30 yards, and 40 yards and this is optional in this invention, although it is preferred. Elk due to their enormous size generally have a pre-set range of from 30 to 60 years, caribou generally have a pre-set range of from 30 to 60 yards, antelope are generally set from 20 to 40 yards, and mule/whitetail deer are set generally from 20 to 50 yards. The lens 1 of this invention is mounted in a holder or support 19 for the lens 1 and the holder 19 is then mounted in an archery sight 25 having pins 26.

Thus, Figure 2 shows one embodiment of a holder and support component 19 that is used to mount the lens 1. The holder and support component 19 consists of a ring or circular configuration 23 that has essentially the same circumferential line as the lens 1. The holder 19 is placed on the surface of the lens 1 and small plates 20 are bolted or screwed down on the lens 1 using bolts 21. In this manner, if one wishes to change from a 20 yard to 40 yard lens 1, to say, a 40 to 70 yard range lens 1, then it is readily accomplished.

Figure 3 is a cross sectional view thorough line 3-3 of Figure 2 to show an enlarged view of the attachment. This is the preferred attachment means, however other means can be used as long as the ring 23 is substantially held in place and the ring 23 or its attachment means does not interfere with the view through the lens 1.

As indicated Supra, the lens 1 can have a semi-circular configuration, a triangular configuration, a square configuration, or a rectangular configuration. Figure 4 shows an archery sight containing a semi-circular lens 1 , Figure 5 shows a rectangular configuration, Figure 6 shows a square configuration and Figure 7 shows a triangular configuration.

The range finder lens of this invention provides a hands-free full draw archery range finder that is designed to fit virtually any bow sight, both left and right hand models. The distances to target are pre-set and thus, there is no need to make any mechanical changes in the range finder during use, nor is it required that the shooter "sight in" such a range finder as the distances are all pre-determined and built into the lens.

Turning now to the archery sight having a semi-circular lens 1 , there is shown in Figure 4, a rear view of an archery sight 25 containing the semi-circular lens 1, a holder 24 for the lens 1, sight pins 26, attachment 27 of the sight pins 26 to the sight 25. This archery sight 25 is for a right handed shooter. In addition, there is shown an attachment means 28 for attachment of the archery sight 25 to an archery bow (not shown). The sight pins 26, pin attachment 27, and attachment means 28 are known in the art and are conventional. Also shown as an optional component of this invention is a level gage 29 for leveling the bow and the sight 25.

In a like manner, shown in Figure 5 is a rectangular configuration of a lens 1 wherein like numbers in Figure 5 have the same meanings as in Figure 4.

In a like manner, shown in Figure 6 is a square configuration of a lens 1 wherein like numbers in Figure 6 have the same meanings as in Figure 4.

In a like manner, shown in Figure 7 is a triangular configuration of a lens 1 wherein like numbers in Figure 7 have the same meanings as in Figure 4.

Turning now to the ring range finder of claim 9, there is shown in Figure 8 one such range finder 30, showing the solid ring 31, and the range finding apparatus, generally at 32. Also shown on Figures 8 and 9 is are indentions 42 in the face of the solid ring 31 that can be used to facilitate a mechanical means to attach the range finder 30 to an archery sight. The indentions can be for example, holes drilled through the solid ring 31 to accommodate pins or screws to fasten the range finder to the archery sight. The range finding apparatus 32 is comprised of the horizontal belly bar 33, its support 34, and the step-wise configuration 35. The step- wise configuration 35 is comprised of a series of horizontal bars 36, 37, and 38 and a series of vertical bars 39, 40, and 41, all of which are connected together. The numbers 36 to 41 have been described as "bars", but they could be thins lines of metal or plastic, or flat plates (which are shown herein in Figures 9 and 10 by way of illustration). Each range finder is pre-set by predetermining the size of the target from belly line to back line that fits into each partial window (in Figure 8, largest is denoted at 100, the middle is denoted as 200, and smallest is denoted as 300) created by the vertical and horizontal lines 36 to 41 using the horizontal belly bar 33 as the base line. These dimensions differ depending on the size of the animal and therefore, range finders are manufactured with markings that describe the particular animal that the range finder is designed for. Then, each of the partial windows can be marked to indicate such sizes, for example in Figure 8 wherein the largest partial window is indicated as 20 yards, the next largest indicated as 30 yards, and the smallest partial window indicated as 40 yards. It is not necessary to mark the partial windows, but it helps the novice hunter find the range much more readily. The ring range finder is manufactured from metal or plastic, and more preferred is metal such as aluminum. Also preferred for the step- wise configuration are flat plates rather than thin metal lines.

The ring range finders can be attached to an archery sight by either mechanical or adhesive means and preferred is using mechanical means, especially mechanical means that can be easily removed to change range finders from one animal size to another animal size.
