Brief Patent Description - Full Patent Description - Patent Application Claims
TECHNICAL FIELD [0001] The present invention relates generally to bow sights, and more specifically to an ambient light collecting sight pin for a bow sight. The present invention is particularly useful in, although not limited to, assisting hunters and/or competition shooters equipped with bows and/or firearms to target game or objects in low-light environments. BACKGROUND OF THE INVENTION [0002] Effective and successful use of a bow is dependent upon a multitude of variables, including establishment of proper trajectory, string tension, drawback and even the weight of the bow. More importantly, however, the precision of a bowshot is largely dependent upon proper targeting or aiming and the ability to sight one's target. As such, many archers/hunters have employed the use of bow sights to assist in such targeting. Unfortunately, however, because most hunting expeditions are usually conducted in low-level light conditions/environments, such as a dense forest, most conventionally available bow sights are unable to effectively assist the hunter in sighting his target. [0003] Although attempts have been made to cure the deficiencies and inadequacies of conventional sighting pins and/or crosshairs, simple bow sights of this sort are of limited use because they fail to provide the archer/hunter with the requisite amount of light needed to sight a target within the bow sight. Furthermore, while bow sights with small light collecting filaments are known, they too serve limited use as they are typically unable to harness enough ambient light to make use of the bow sight worthwhile. [0004] Therefore, it is readily apparent that there is a need for an ambient light collecting sight pin for a bow sight, wherein the present invention effectively harnesses diminutive amounts of ambient light and magnifies same to a useable light source capable of assisting hunters in sighting their targets in low-light environments. BRIEF SUMMARY OF THE INVENTION [0005] Briefly described, in a preferred embodiment, the present invention overcomes the above-mentioned disadvantage, and meets the recognized need for such a device by providing ambient light collecting sight pins for a bow sight, wherein the sight pins comprise coiled fiber optic filaments for effectively harnessing diminutive amounts of ambient light and magnifying same to a useable light source capable of assisting hunters in sighting their targets in low-light environments. [0006] According to its major aspects and broadly stated, the present invention in its preferred form is an ambient light collecting sight pin for a bow sight, wherein the sight pin generally comprises a light collecting filament and a translucent spool or housing integrally formed with, or otherwise adapted to, the sight pin. [0007] More specifically, the present invention is an ambient light collecting sight pin for a bow sight, comprising a light collecting filament preferably in the form of a scintillating fiber optic filament of sufficient length to enable extensive wrapping or winding of the filament around or within a preferably translucent spool or housing, wherein the spool or housing is preferably integrally formed with, or otherwise adapted to, the sight pin. Moreover, a portion of the fiber optic filament retained on or within the spool or housing is guided around and removably secured to the sight pin, such that the terminal end of the filament resides at the tip of the sight pin. [0008] Preferably, the repeated wrapping or winding of the lengthy strand of fiber optic filament configures the filament to provide an enhanced surface area over which to harness ambient light. The translucent material from which the spool or housing is constructed further enables ambient light to pass therethrough, and thus be harnessed by the wrapped filament. Accordingly, the terminal end of the portion of filament removably secured to the tip of the sight pin is preferably illuminated as a result of the harnessed ambient light. [0009] In use, a plurality of such lit sight pins, each having filaments of differing color, may be removable secured to a bow sight generally adapted to receive sight pins. Additionally, the bow sight may be constructed from a translucent material to assist in the overall light-harnessing process of each fiber optic filament. [0010] Accordingly, a feature and advantage of the present invention is its ability to provide a bow sight having interchangeable, light-harnessing sight pins. [0011] Another feature and advantage of the present invention is its ability to be utilized in extremely low-level light environments. [0012] Still another feature and advantage of the present invention is its ability to effectively harness ambient low-level light and magnify it to a useable light source. [0013] Yet another feature and advantage of the present invention is its ability to allow the archer/hunter to sight targets in low-level light environments. [0014] Still yet another feature and advantage of the present invention is its ability to provide a large, multi-coiled ambient light collecting surface area. [0015] These and other features and advantages of the invention will become more apparent to one skilled in the art from the following description and claims when read in light of the accompanying drawings.
