Abstract:
A bow sight mounting system including a forward sight assembly used with conjunction with a rearward sight assembly adjustably mounted to a base plate, each component considered modular. The forward sight assembly, interchangeable with identical parts in the rearward sight assembly, includes two pin sight assemblies, two sight mounting brackets and two moveable connecting bars terminating in a base mounting plate. The base mounting plate is symmetrical with the ability to mount on a left-hand or right-hand bow. The moveable connecting bars extends perpendicular to the bow frame and base mounting plate and locates the sight mounting bracket in position to be inline with the bowstring. The forward pin sight assembly containing a vertical pin works with conjunction with the rearward pin sight assembly containing two vertical pins. The rearward vertical pins are positioned as such to create an open gap alignable with the forward pin and the target.

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates generally to bow sights and more specifically it relates to a modular and interchangeable type bow sight mounting system for providing an archery sighting system which eliminates the need for a peep sight while assisting the archer in maintaining consistent form to circumvent bow torque. 
     Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field. 
     When a person decides to take up the sport of archery the two required items are the projectile, or arrow, and the mechanism to launch the projectile, the bow. Everything else is an accessory. The present invention generally relates to one of the more important accessories for the archery equipment. More particularly, this invention is related to a bow mounted sighting mechanism which can be used to accurately aim the bow at a target thereby improving the shooting accuracy of the archer. 
     It has long been recognized that a bow is a difficult weapon to shoot with consistent accuracy. There are two primary systems archers employ in aiming to produce consistent accuracy. The most basic system, or method, is “instinct”. Instinct shooters rely on both their shooting experience and their familiarity with their equipment to compensate for the various accuracy influencing factors. Instinct shooting requires a tremendous amount of practice and concentration to be effective. When hunting, the adrenaline of the moment can dramatically influence concentration and aiming at the target becomes considerably more difficult resulting in a complete miss, or worse a poor shot. 
     The second system the archer may use to improve accuracy is to purchase one of the numerous types of bow sights on the market. Bow sights enable the archer to more consistently hold the bow in the same orientation for a shot at a given distance. The bow sight mounts to the riser of the bow and the sight houses one or more sight pins. The pins are vertically spaced from one another and are individually set by the archer so that each pin corresponds with a predetermined distance to the target. 
     A problem with this system of alignment device is that the pins each provide only a single reference point to be used in connection with aiming of the bow. What often happens is the orientation or attitude of the bow is altered between successive shots at the same distances so that, merely using the same sight pin will not always result in an accurate shot. This realization has lead to the development of what are herein referred to as secondary sights. 
     Perhaps the most commonly known secondary sight is the bow string mounted “peep” sight. During its use, the peep is mounted to the bow string and once the bow string is drawn, the archer looks through the peep sight to align the appropriate sight pin on the target. Although generally considered to be better than a single front pin, these systems also have their disadvantages and limitations. One limitation is the difficulty with which a peep is mounted to the bow string so that it will consistently offer a clear view of the sight pins and the target. Another problem, and often more significant, is that when looking through the small aperture of the peep, the amount of light available to the archer for viewing the pin and the target is significantly diminished thereby often drastically inhibiting vision of the target. This is compounded by the fact that the best hunting times are generally considered to occur during the marginal light conditions of dawn and dusk. As the archer ages his/her near-vision usually diminishes compounding further the problems associated with peep sights. The archer then has a tendency to “look over” the peep as adrenaline takes over when aiming at a live target in order to acquire a better view of the target. Looking over the peep is often the cause for a complete miss at a live target. If the archer has both eyes open the low light condition created by the peep can transfer the normally dominate eye to the opposite eye altering the point of impact so much so that the target is completely missed. A solution for low light availability of peep sights is to use a larger peep. However, the larger the peep the more room for sighting error and a less accurate shot results. 
     Whether a peep is used or not, another aiming problem arises when the archer torques the bow slightly. If the bow is gripped differently or the archer squeezes the handle of the bow, “torque” is produced and is observable at the target as a left or right miss. Bow torque on single sighting systems and single sighting systems in conjunction with a peep is not observable. Only after the arrow is released to the target and a left or right miss is observed is bow torque realized. This realization and the need to eliminate the low light problems associated with peep sights have lead to the development of alternate variety of secondary sights. 
     An alternate variety of bow sight eliminates the peep and mounts a supplemental rear sight in combination with the front sight. While there are literally hundreds of traditional types of bow sights commercially available, each requiring a peep for best accuracy, there are only a few types of this alternate variety of rear bow sight commercially available. Rear sights in prior art, such as U.S. Pat. No. 5,671,724, have generally included movable parts and a cross hair sight which obstructed visibility of the forward sight and the target itself. This and prior art, such as U.S. Pat. No. 7,275,327 and U.S. Pat. No. 6,003,233, involving complicated aiming techniques, are not built rugged to withstand the occasional snag with brush or other abuse without damage. Preliminary calculations using a torque formula indicate it would take 85 to 125 pounds of force to bend the windage adjustment of the aforementioned bow sights if mounted an inch from the mounting plate. Other prior art, such as U.S. Pat. No. 6,463,665 and U.S. Pat. No. 5,040,301 use a single string or cable on the rear sight which only allow for windage adjustment. Still a another prior art of this rear sight variety, application Ser. No. 11/482,381, while twice as costly as the other two, lacks the spatial accuracy as the other designs by mounting both sighting apparatus in close proximity and in front of the bow riser. This last design also appears cluttered as it obscures much of the viewing area of the target with crosshair, aperture, and pin combination. 
     This invention was developed to address a number of issues associated with other sights and sighting systems. Many manufacturers of front only mounted bow sights have switched from horizontally mounted pins to vertically mounted pins. The advantage of a vertical mounted pin is a clear, unobstructed view of the target. U.S. Pat. No. 5,671,724 and application Ser. No. 11/482,381 use rear crosshair sights and U.S. Pat. No. 7,275,327 and U.S. Pat. No. 6,003,233 uses a v-notch rear sight. This invention uses two rear opposing vertical pins in combination with a single front pin. Also, a single pin, desired by many archers, helps eliminate clutter associated with multiple pins. The two rear vertical pins could be used as additional yardage sights with the upper used for shorter distances and the lower for longer distances. As previously stated, the windage adjustments on other inventions were deemed inadequate for strength; this invention addressed this issue by using a mass to withstand over 700 pounds of torque. Circular rings housing pins are used because the human eye naturally gravitates to the center. This invention uses circular rings for the front and rear to aid in alignment. The combination front and rear vertical pins accomplish two more issues: the low light problems and alignment issues associated with peep sights, as stated earlier, allow the archer to eliminate the peep and thus eliminate those low light and alignment issues; bow torque is observed before the archer releases the arrow to the target eliminating left and right misses. Finally, this invention addresses two issues not addressed in other sights: all in-field adjustments for windage and elevation are accomplished with a single tool; this invention, without alteration, can be installed on either a left-hand or right-hand bow with the front windage, elevation, and pin sight assembly and mounting system parts being identical, interchangeable, and can be considered modular. 
     While the examples given are illustrative of some of the sights which have been developed to assist an archer in improving shooting accuracy, they all generally either fail to permit adequate sighting during low light shooting conditions or are not built to withstand the rugged outdoors. With so few commercially rear sight in combination with the front sight options available there is obviously still a need in the field of this invention for an improved bow sight which can be used to more accurately aim the bow at a target, without complicating the shooting process, and without further compromising vision during low light situations of dusk and dawn, rugged enough to withstand the abuse it may endure, and make field adjustments with a single tool. The intention of the invention, as outlined, was to build a bow sight to eliminate the use of a peep, have an unobstructed view of the target, and to have a sight which was essentially impervious from damage. After numerous prototypes the realization of this invention had qualities not seen in other archery sights. Additionally, the symmetry and interchangeability of parts are unique to this invention.

     DETAILED DESCRIPTION OF THE INVENTION 
     A. Overview 
     Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, the figures illustrate various views of the Dual Interchangeable Type Bow Sight  10  a base mounting plate  12  for mounting to a bow&#39;s riser, identical and interchangeable moveable connecting bars  30 , identical and interchangeable adjustable sight mounting brackets  40 , and identical and interchangeable pin sight assembly  50 . 
     B. Base Mounting Plate  12   
     The base mounting plate  12  is a contoured elongated symmetrical structure of light-weight material in plate thickness having mirror imaged identical ends comprising of a receiver for accepting a moveable extension bar and having sufficient length to accommodate a sight in forward and rearward positions of a bow riser. The function of said base plate is the mounting to the bow riser, mounting after market accessories, and accepting said moveable extension bar. The symmetry of said base mounting plate enables a bow of left-hand or right-hand design to accept connection without compromise. 
     Referring to  FIG. 4  and  FIG. 5 , symmetrically designed base mounting plate  12 , containing eight countersunk holes  14 ; four as viewed from the inside and four as viewed from the outside of the mounting plate. Countersunk holes  14  function is mounting on a bow&#39;s riser. Symmetry of base mounting plate  12  allows mounting on right-hand designed bows or left-hand designed bows, and forward and rearward position of base mounting plate  12  is relative to the bow design. Countersunk holes  14  allows for the use of commercially sold countersunk screws for flush mounting. Base mounting plate  12  also contains two threaded holes  16  whereas spacing of said threaded holes  16  accepts commercial after-market accessories. Two holes  18  accept the pass through of commercially sold fastener  60 . Two threaded holes  20  accept the threads of fastener  60 . Tightening or loosening said fastener  60  compresses or relaxes compression space  24  and decreases or increases opening of compression slots for extension bar  22 . Flexibility of said compression slots for extension bar  22  is dependent on compression cutout area  26 . Center cutout area  28  is for purpose of weight reduction. 
     C. Moveable Connecting Bars  30   
     The identical and interchangeable moveable connecting bars  30  structures is a commercially available hex bar stock. The function of said moveable connecting bars  30  is to permit windage, or side-to-side adjustment, and is of sufficient length to accomplish this purpose. The moveable connecting bars  30  is connected to the base mounting plate through previously stated compression slots for extension bar and secured with a fastener. 
     Referring to  FIG. 4  and  FIG. 6 , one end of bar  32  of moveable connecting bars  30  is recessed to create ear mounting slot  34  to a depth made to match the thickness of sight mounting brackets  40 . Width of said ear mounting slot  34  is sufficient to ensure hole  44  in mounting ear  42  of said sight mounting brackets  40  matches the position of threaded hole  36  on said moveable connecting bars  30 . The design of said ear mounting slot  34  is a means of connection and mating of said mounting ear  42 . The anti-rotation ear  38  is designed to prevent rotation of identical and interchangeable said sight mounting brackets  40 . Threaded hole  36  is of sufficient depth to accept standard commercially available fastener  64 . Both moveable connecting bars  30  are identical in every respect and are interchangeable. This component is considered to be modular and could be replaced by an alternative component suited to be substituted with this or another portion of the invention. 
     D. Sight Mounting Brackets  40   
     The identical and interchangeable sight mounting brackets  40  are a rectangular shaped structure of plate thickness. The function of said sight mounting brackets is to provide a means for elevation adjustments of the pin sight assembly  50 . A shallow wide slot  46  is produced in each said sight mounting plate as a means to connect to a mating portion on said pin sight assembly  50 . 
     Referring to  FIG. 1 ,  FIG. 4 , and  FIG. 7 , the contour geometry of mounting ear  42  of sight mounting brackets  40  matches the hex shape of moveable connecting bars  30  when connected in recessed area for ear mounting slot  34  through hole  44  to threaded hole  36  with fastener  64  as illustrated in  FIG. 1  ensuring sight mounting brackets  40  will not rotate in space. Wide slot  46  is shaped to a width wide enough to ensure a stable platform for rise  54  and a depth deep enough to ensure pin sight assembly  50  does not rotate when fasten through small slot  48  with fastener  62 . Length of small slot  48  is of sufficient length to move pin sight assembly  50  up and down for all typical target acquisition elevation positions. Both sight mounting brackets  40  are identical in every respect and are interchangeable. This component is considered to be modular and could be replaced by an alternative component suited to be substituted with this or another portion of the invention. 
     E. Pin Sight Assembly  50   
     The pin sight assembly  50  structure is composed of durable high impact translucent material. Said pin sight assembly  50  is generally circular in shape with a depth approximately one half the diameter of said circular sight. The diameter of said pin sight assembly  50  is large enough to permit ample field of view. The function of said pin sight assembly  50  in the forward position is to house a single commercially available replaceable t pin  66  allowing for target acquisition. The function of said pin sight assembly  50  in the rearward position is to house two commercially available replaceable pins  68 , of different color, located in opposition for position centering of said forward pin  66  in said pin sight assembly  50  in the forward position. Pin sight assembly  50  is connected to one of the sight mounting brackets  40  as a rise  54  on said forward pin sight assembly  50  is mated into the previous said wide slot  46  and secured with fastener  62 . The pin sight assembly  50  component is considered to be modular and could be replaced by an alternative component suited to be substituted with this or another portion of the invention. 
     Referring to  FIG. 4  and  FIG. 8 , rise  54  on pin sight assembly  50  is shaped to a width easily moveable when mated to wide slot  46  in sight mounting brackets  40 . Rise  54  is shaped to match the depth of wide slot  46  in sight mounting brackets  40 . Hole  52  in the center of rise  54 , accepts a commercially available threaded insert. Said threaded insert is also known as a “heli-coil”. Hole  58  in the center of long slot  56  accepts a fastener for commercially available replaceable pin  66  and pins  68 . 
     F. Connections of Main Elements and Sub-Elements of Invention 
     Referring to  FIG. 4  and  FIG. 5 , the base mounting plate  12  is fasten to a right-hand or left-hand commercially sold bow with commercially available countersunk screws through either of the two vertically opposing countersunk holes  14 . Countersunk hole selection has two preference positions based on bow design and archers personal preference. One of the two forward vertically opposing countersunk holes  14  is paired for one mounting position and the other rearward vertically opposing countersunk holes are paired to constitute a second mounting position. Either mounting positions will fit any commercially sold bow. Moveable connecting bars  30  are inserted through compression slots for extension bar  22  on the base mounting plate  12  and fastened with fastener  60  through holes  18  and secured into threaded holes  20 . Sight mounting brackets  40  are mounted to the moveable connecting bars  30  by mating mounting ear  42  to ear mounting slot  34  with fastener  64  through hole  44  and secured into threaded hole  36 . Pin sight assembly  50  is mounted to sight mounting brackets  40  by mating rise  54  into wide slot  46  with one of the fastener  62  through small slot  48  and secured to threaded insert in hole  52 . For making in-field windage and elevation adjustments fastener  60  and fastener  62  are adjusted using the same tool. The commercially available replaceable pin  66  and pins  68  is inserted into long slot  56  of pin sight assembly  50  and is secured with the commercially available replaceable pin fastener through hole  58 . 
     G. Alternative Embodiments of Invention 
     Referring to  FIG. 1 ,  FIG. 2 , and to  FIG. 3  it can be seen the intended use of this invention is to position forward sight pin  66  in the center of rearward sight pins  68  for target acquisition. While a circular sight aids the archer in naturally centering, altering the geometric shape of the sight pin assembly does not alter the functionality of this invention. 
     Referring to  FIG. 6  and  FIG. 7 , moveable connecting bars  30  and sight mounting brackets  40  are separate main elements. As an alternative, production processes could mold both elements into a single main element thus eliminating secondary operations and connections of said moveable connecting bars  30  to said sight mounting brackets  40 . 
     H. Operation of Preferred Embodiment 
     The connections of main elements and sub-elements have already been described and are shown in  FIG. 1  and  FIG. 4 . The choice of which countersunk holes to use, as already stated, may be of personal preference or bow design. In most cases the choice of which countersunk mounting hole is personal preference. Some bows have an extended brace in the rear of the bow grip area. In cases such as this, the base mounting plate  12  must use the rearward countersunk holes. The archery industry sets standards for diameter of threaded fasteners for mounting “bow sight side plates” to the bow&#39;s riser and countersunk holes  14  meets those standards. The archery industry also sets standards for location spacing of the threaded fasteners for mounting “bow sight side plates” to the bow&#39;s riser and these location standards of countersunk holes  14  in base mounting plate  12  meet the industry&#39;s location standards. Accessories, such as arrow quivers, may be mounted to the base mounting plate  12  by using threaded holes  16 . The archery industry sets standards for spacing for accessories and the spacing of threaded holes  16  in base mounting plate  12  meets the industry standards. 
     Because base mounting plate  12  is symmetrical the same plate can be used on a left-hand or right-hand designed bow. Also, the plate may be mounted with holes  18  positioned facing upward or facing downward. It is, however, preferable to position holes  18  facing upward, as shown in  FIG. 4  and  FIG. 5 , in the event the archer, while making windage adjustments, forgets to tighten the fasteners. Positioning holes  18  facing upward will prevent the fasteners from falling out and being lost as might be the case if holes  18  were facing downward. 
     Because moveable connecting bars  30  and sight mounting brackets  40  are identical and symmetrical, elements may be exchanged to mount in the forward or rearward position whether base mounting plate  12  is mounted on the riser of a right-hand bow or the riser on a left-hand bow. 
     Because pin sight assembly  50  is symmetrical, mounting to sight mounting brackets  40  in the right-hand riser position or left-hand riser position may be made in a plurality of ways. 
     Referring to  FIG. 1  and  FIG. 2 , pin sight assembly  50  in the forward position shows pin  66  mounted in the lower position of long slot  56 . The archer has two choices when mounting pin sight assembly  50  in the forward position to sight mounting brackets  40  on a right-hand bow riser or left-hand bow riser. Pin sight assembly  50  may be mounted to have pin  66  positioned in lower long slot  56  as shown in  FIG. 1  and  FIG. 2 , or pin sight assembly  50  may be mounted to have pin  66  positioned in the upper long slot  56 . Since pin  66  in the forward positioned pin sight assembly  50  is centered between the two pins  68  in the rearward positioned pin sight assembly  50 , the orientation of pin  66  downward or upward is insignificant. Of importance is rotation of pin  66  is visible to the archer when in the shooting position. Pin  66  may be removed, rotated 180 degrees, and re-secured so as to be visible to the archer. 
     Operations of the remaining main elements involve windage and elevation adjustments. After an archer nocks an arrow and shoots at a target, if the arrow impacts too low, forward pin sight assembly  50  is moved downward by loosening fastener  62  and sliding forward pin sight assembly  50  downward. If the arrow impacts too high, forward pin sight assembly  50  is moved upward by loosening fastener  62  and sliding forward pin sight assembly  50  upward. 
     After an archer nocks an arrow and shoots at a target, if the arrow impacts too far to the right, moveable connecting bars  30  is moved to the right by loosening fastener  60  and sliding moveable connecting bars  30  to the right. If the arrow impacts too far to the left, move moveable connecting bars  30  to the left by loosening fastener  60  and sliding moveable connecting bars  30  to the left. 
     Rearward mounted pin sight assembly  50  adjustments should match the placement of the forward mounted pin sight assembly. Upward, downward, left or right adjustments of the rearward mounted pin sight assembly  50  should match upward, downward, left or right adjustments of the forward mounted pin sight assembly. Small adjustments to forward mounted pin sight assembly  50  may be made without adjustments to rearward mounted pin sight assembly. As previously mentioned, fastener  60  and fastener  62  for making in-field windage and elevation adjustments are made with the same tool. In the event fastener  64  requires tightening the same tool can be used as was for fastener  60  and fastener  62 . 
     What has been described and illustrated herein is a preferred embodiment of the invention along with some of its variations. Each main element component is considered to be modular and could be replaced by an alternative component suited to be substituted with this or another portion of the invention. The terms, descriptions and figures used herein are set forth by way of illustration only and are not meant as limitations. Those skilled in the art will recognize that many variations are possible within the spirit and scope of the invention in which all terms are meant in their broadest, reasonable sense unless otherwise indicated.
