BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to archery equipment. More specifically, the present invention is directed to a variety of colored transparent bow sights attached to the bow-strings of target practice or hunting bows, and either with or without an elastic connection such as a rubber or a battery-assisted light from the bow handle to the bowstring.
2. Description of the Related Art
The related art of interest describes various bow sights, but none discloses the present invention. There is a need for a sighting device containing fiber optics placed on a bowstring for improving one's accuracy with or without an elastic cord connecting the bow and the rear bow sight. Alternatively, a battery-assisted light emitting diode (LED) can illuminate the fiber optics with the electrical connection acting similarly to the rubber band. The problem of visibility when aiming an arrow at a target arises in limited light conditions such as early dawn and dusk. Bow sights of the present invention aid in increasing the light without an illumination aid where a jurisdiction prohibits the use of any lighting in attracting game. When self-illumination is permitted in a State, the battery and LED embodiment can be utilized. The following patents are examples of inventions that attempt to achieve better aiming for bow hunters.

SUMMARY OF THE INVENTION
The present invention is directed to transparent rear bow sights having fiber optics of various configurations and preferably enhanced with a battery to be attached to a bowstring. These bow sights can be used with or without an elastic alignment cord attached to the bow handle and bowstring. The simplest form of a rear bow sight has a dark colored base including a colored fiber optic and supporting an inclined circular apertured sight with external notches for embedding the individual or grouped drawstrings. Other embodiments include various arrangements of the fiber optic as a U-shaped tube, a singular straight tube, two parallel straight tubes, and a combination of a straight tube between the legs of a horseshoe-shaped tube. Then, a modification of an offset colored optic sight on its base which is clamped onto the bowstring is presented. The fiber optic tubes have tritium included in the composition which enhances the light gathering ability. A second modification of an optic sight includes the alignment or misalignment of the fiber optic tube on its base. A third modification of an optic sight includes a post attached in alignment with or skewed with the base for attachment of a rubber cord. A fourth modification includes the angular positioning of the sight window on the base as inclined or perpendicular. A fifth modification includes the coiling of part of the fiber optic pin several times around a post which is in-line or skewed with the base. These modifications of the fiber optic pins, the sight windows and the addition of a post provide an assortment of sighting aids in deficient light conditions to enable the accurate shooting down of game.
Accordingly, it is a principal object of the invention to provide a rear bow sight utilizing transparent colored fiber optic pins filled with tritium and attached to a bowstring.
It is another object of the invention to provide a rear transparent colored fiber optic bow sight assortment with up to three fiber optic tubes and being either aligned or skewed on a base.
It is a further object of the invention to provide a rear transparent colored fiber optic bow sight assortment with sight windows perpendicular or inclined on its base and having a variety of external notches for embedding the individual or grouped drawstrings.
It is a further object of the invention to provide a rear transparent colored fiber optic bow sight assortment wherein the base portion is clamped onto the bowstring.
Still another object of the invention is to provide a rear transparent colored fiber optic bow sight assortment wherein a post is attached either in alignment or skewed with the base.
Yet a further object of the invention to provide a rear transparent colored fiber optic bow sight assortment wherein the fiber optic tube is initially coiled around a post extending from the base.
Yet still another object of the invention is to provide a rear transparent colored fiber optic bow sight assortment with a battery attached to the bowstring.
Yet another object of the invention is to provide a rear transparent colored fiber optic bow sight assortment with an elastic cord attached to the handle and the bowstring.
It is an object of the invention to provide improved elements and arrangements thereof for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes.
These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.
