Definitions
- the present invention pertains to archery sights. More particularly, the present invention pertains to archery sights employing fiber optic technology. More particularly still, the present invention pertains to an archery sight having versatile and durable pins that support fiber optic cables.
- Bows can be shot without using a sight for aiming.
- shooting without a sight has become increasingly challenging, especially at longer ranges.
- archery sights have become much more common in recent years.
- Modern bows, and particularly compound bows, are typically equipped with some type of bow sight.
- bow sights work by providing feedback regarding where a projectile (arrow) is pointed.
- bow sights have many different configurations, bow sights are typically mounted on bow risers.
- Archery sights come in a number of different configurations and levels of sophistication.
- One very common type of sight is known as a “fixed pin” sight.
- Fixed-pin sights typically have a plurality of individual pins, which can each be set to correspond with a particular known distance. Once set, the pins are secured or locked into place and remain “fixed” in position during use.
- Such fixed pin sights are generally very reliable and easy-to-use, even in the field.
- Archers typically set their fixed pins to correspond to distances that are easy to remember, usually in 5 or 10 yard increments. Once the pins are set, shooting known distances is relatively easy. However, archers using fixed-pin sights frequently must learn to compensate for intermediate distances for which no pin is set. For example, if a target is 45 yards away, a 40 yard pin will aim too low while a 50 yard pin will aim too high. As a result, archers using fixed-pin sights must learn to “split the difference” between the pins using a practice commonly referred to as “gap-shooting”.
- Fiber optic cables typically comprise a strand of optically pure glass or plastic surrounded by cladding.
- the cladding reflects light into the core of the cable.
- sunlight or any other light source
- light travels to the end of the cable where the core is exposed.
- the end tip of the cable appears to “light-up”, as if energized by an external power source.
- the longer the fiber-optic cable the more light it can gather and the brighter the tip becomes.
- the small bright tip of a fiber optic cable makes an excellent aiming point on an archery sight. Even in low light conditions (for example, early in the morning or late in the evening), the tip of the fiber optic cable still stands out, thereby allowing the archer to effectively aim using the sight even in such low-light conditions.
- pins As more pins are mounted in an archery sight, such pins can be set for smaller yardage increments, thereby reducing the need for gap shooting. However, when numerous pins are mounted in a sight, more of the target can be obscured behind such pins. This situation can make aiming more difficult, especially for certain bows with small pin-gaps.
- the present invention comprises an archery sight having at least one fiber optic sight pin, as well as a method for using same.
- An archer can utilize the method and apparatus of the present invention to set pre-determined distances which the archer can then use to aim a bow, such as a compound bow or the like.
- the optical sight pins of the present invention can be beneficially manufactured using a metal injection molding (“MIM”) process known to those having skill in the art.
- MIM metal injection molding
- the optical sight pins of the present invention are constructed of stainless steel; said optical sight pins of the present invention are not machined from aluminum made of plastic like conventional prior art sight pins.
- Each individual optical sight pin of the present invention comprises a substantially square mounting block on one end, said block having a threaded bore.
- a socket head cap screw and washers can be used to fasten or secure each optical sight pin in elongate slots in a sight window which, in turn, forms part of a bow sight.
- Each sight pin is slidably disposed within a slot and can be locked in place in a desired location.
- Each optical sight pin of the present invention includes at least one eyelet on the back of such pin. Said at least one eyelet is located on the optic sight pin for maximum holding strength of a fiber optic cable attached to such optical sight pin.
- each eyelet on each optical sight pin has a diameter of no larger than 0.031′′ and no smaller than 0.012′′, to permit use of different size fiber optic cables within said eyelets. The fiber optic cable is then threaded through the eyelets and fastened on one end for viewing by the archer.
- the optical sight pins of the present invention comprise blade style or shaped sight pins.
- each optic sight pin is also designed and built with a beneficial twelve (12) degree offset angle which gives each pin strength that greatly exceeds conventional prior art sight pins.
- the design and shape of the optical sight pins of the present invention result in a sight pin pattern in the sight window of the bow sight that does not obscure or block the target from view.

Abstract
An archery sight assembly for aiming bows including, without limitation, compound bows. An adjustable mounting bracket connects the archery sight assembly to a bow and permits position adjustment of a sight window relative to the bow. At least two rigid optical sight pins are visible through the sight window. A length of fiber optic cable extends from the tip of a first optical sight pin, through a transparent housing, and attaches to the tip of a second optical sight pin. The optical sight pins have an offset angle to provide a gap between the pins, thereby improving the archer's field of vision.

- 1. Field of the Invention
- The present invention pertains to archery sights. More particularly, the present invention pertains to archery sights employing fiber optic technology. More particularly still, the present invention pertains to an archery sight having versatile and durable pins that support fiber optic cables.
- 2. Brief Description of the Prior Art
- Bows can be shot without using a sight for aiming. However, as technology improves and bows become more powerful, shooting without a sight has become increasingly challenging, especially at longer ranges. As such, archery sights have become much more common in recent years. Modern bows, and particularly compound bows, are typically equipped with some type of bow sight.
- Much like a sight at the end of a gun barrel, a bow sight helps an archer aim arrows shot from a bow. Generally, bow sights work by providing feedback regarding where a projectile (arrow) is pointed. Although bow sights have many different configurations, bow sights are typically mounted on bow risers.
- Archery sights come in a number of different configurations and levels of sophistication. One very common type of sight is known as a “fixed pin” sight. Fixed-pin sights typically have a plurality of individual pins, which can each be set to correspond with a particular known distance. Once set, the pins are secured or locked into place and remain “fixed” in position during use. Such fixed pin sights are generally very reliable and easy-to-use, even in the field.
- Archers typically set their fixed pins to correspond to distances that are easy to remember, usually in 5 or 10 yard increments. Once the pins are set, shooting known distances is relatively easy. However, archers using fixed-pin sights frequently must learn to compensate for intermediate distances for which no pin is set. For example, if a target is 45 yards away, a 40 yard pin will aim too low while a 50 yard pin will aim too high. As a result, archers using fixed-pin sights must learn to “split the difference” between the pins using a practice commonly referred to as “gap-shooting”.
- Archery sights typically employ fiber optic strands/cables to improve the aiming process. Fiber optic cables typically comprise a strand of optically pure glass or plastic surrounded by cladding. The cladding reflects light into the core of the cable. Thus, when the fiber optic cable is exposed to sunlight (or any other light source), light travels to the end of the cable where the core is exposed. In this manner, the end tip of the cable appears to “light-up”, as if energized by an external power source. Generally, the longer the fiber-optic cable, the more light it can gather and the brighter the tip becomes.
- The small bright tip of a fiber optic cable makes an excellent aiming point on an archery sight. Even in low light conditions (for example, early in the morning or late in the evening), the tip of the fiber optic cable still stands out, thereby allowing the archer to effectively aim using the sight even in such low-light conditions.
- As more pins are mounted in an archery sight, such pins can be set for smaller yardage increments, thereby reducing the need for gap shooting. However, when numerous pins are mounted in a sight, more of the target can be obscured behind such pins. This situation can make aiming more difficult, especially for certain bows with small pin-gaps.
- Thus, there is a need for an improved archery sight that permits the use of multiple pins without blocking the view of an archer or otherwise obscuring the target behind such pins. The pins should be strong and durable, while permitting quick and efficient position adjustment.
- The present invention comprises an archery sight having at least one fiber optic sight pin, as well as a method for using same. An archer can utilize the method and apparatus of the present invention to set pre-determined distances which the archer can then use to aim a bow, such as a compound bow or the like.
- In a preferred embodiment, the optical sight pins of the present invention can be beneficially manufactured using a metal injection molding (“MIM”) process known to those having skill in the art. In a preferred embodiment, the optical sight pins of the present invention are constructed of stainless steel; said optical sight pins of the present invention are not machined from aluminum made of plastic like conventional prior art sight pins.
- Each individual optical sight pin of the present invention comprises a substantially square mounting block on one end, said block having a threaded bore. A socket head cap screw and washers can be used to fasten or secure each optical sight pin in elongate slots in a sight window which, in turn, forms part of a bow sight. Each sight pin is slidably disposed within a slot and can be locked in place in a desired location.
- Each optical sight pin of the present invention includes at least one eyelet on the back of such pin. Said at least one eyelet is located on the optic sight pin for maximum holding strength of a fiber optic cable attached to such optical sight pin. In a preferred embodiment, each eyelet on each optical sight pin has a diameter of no larger than 0.031″ and no smaller than 0.012″, to permit use of different size fiber optic cables within said eyelets. The fiber optic cable is then threaded through the eyelets and fastened on one end for viewing by the archer.
- In a preferred embodiment, the optical sight pins of the present invention comprise blade style or shaped sight pins. In a preferred embodiment, each optic sight pin is also designed and built with a beneficial twelve (12) degree offset angle which gives each pin strength that greatly exceeds conventional prior art sight pins. The design and shape of the optical sight pins of the present invention result in a sight pin pattern in the sight window of the bow sight that does not obscure or block the target from view.
- Dimensions set forth herein and in the attached drawings and/or photographs are illustrative only and are not intended to be, and should not be construed as, limiting in any way.
- The foregoing summary, as well as the following detailed description of preferred embodiments, is better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, the drawings show certain preferred embodiments. It is understood, however, that the invention is not limited to the specific methods and devices disclosed.
