## Title
Hinged archery sight for a bow for shooting arrows

## Abstract

A hinged archery sight for a bow for shooting arrows includes an oval configured sight portion when the hinged archery sight is disposed in a substantially vertical position, and a substantially annular configuration when the hinged archery sight is disposed in a predetermined angular position corresponding to an archer's draw on the bow string. The hinged archery sight also includes hinged portion for pivotally securing the archery sight to a bow string. To maintain a predetermined optimum position of the hinged archery sight on the bow string, securing spikes are integrally joined to inner walls of bow string receiving recesses such that pointed ends of the securing spikes radially penetrate the bow string when the hinged archery sight is secured about the bow string.

## Background
This is a Continuation-In-Part Application of pending application Ser. No. 15/004,937, filed on Jan. 23, 2016.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to archery sights secured to a bowstring, and more particularly, to an archery sight that has a hinged portion that enables front and back portions of the hinged sight to be pivotally secured together on one side such that an opposite side of the hinged sight can be manually “opened” to receive a bowstring, whereupon, fasteners secure portions of the hinged archery about the bowstring.
Further, the present invention relates to maintaining a predetermined position of the archery sight upon the bowstring via pointed protrusions extending from an inner portion of the archery sight into the bowstring, thereby grasping and securing the position of the archery sight relative to the bowstring irrespective of the vibration force generated by the bowstring when shooting an arrow.
2. Background of the Prior Art
Prior art archery sights are secured to a bowstring by intertwining the sight with the bowstring, or by securing separated front and back portions of an archery sight about the bowstring, such that the bowstring is ultimately “squeezed” between the front and back portions via fasteners inserted through and manually tightened upon both front and back portions on opposite sides of the bowstring.
A problem arises when an archer attempts to attach a prior art sight upon the bowstring. More specifically, the archer has to hold front and back portions of the sight about the bowstring while aligning cooperating apertures in the front and back portions to receive fasteners that are manually rotated to secure the bowstring between the front and back portions, and between predetermined fasteners. This prior art procedure for securing the sight to the bowstring is problematic in that it takes the archer a relatively excessive amount of time to visually align the apertures in the front and back portions while engaging the bowstring disposed between the front and back portions, which are being held by one hand of the archer. The archer must then secure the front and back portions together via fasteners rotationally secured to the front and back portions. The procedure is especially difficult to complete in cold and/or wet climates.
Another problem arises when an arrow is shot from a bowstring having a hinged archery sight secured thereto. More specifically, irrespective of the material of fabrication for the archery sight and how tight the archery sight is secured about the bow string, the vibrations generated by the bow string when shooting an arrow results in the archery sight sliding or otherwise moving from the optimum position selected by the archer for the archery sight upon the bow string.
Still another problem arises when a hinged archery sight is configured with a relatively large sight aperture opposite a lower securing screw with the bow string disposed between the sight aperture and the lower securing screw. The dimensions of the sight aperture prevent a second lower securing screw from being disposed adjacent to the sight aperture and opposite the lower securing screw, resulting in lower portions of front and back members separating proximate to the sight aperture, thereby causing an accelerated degradation of the tensile force tolerated by the bow string when the bow string is drawn by an archer.
There is a need for an archery sight that promotes pivotal separation of front and back portions of the sight that results in the “opening” of a predetermined portion of the sight to receive a bowstring, and that provides “automatic” alignment between cooperating fastener apertures in the front and back portions when the front and back portions are manually urged together, thereby allowing the archer to manually secure the front and back portions together without the archer having to visually align the cooperating fastener apertures. Further, there is a need for securing elements integrally joined to and projecting from recess walls, which receive and engage the bow string, such that the securing elements penetrate the bow string, thereby preventing the archery sight from moving upon the bow string irrespective of vibration forces generated by the bow string when shooting an arrow. Also, there is a need for increasing the diameter of a lower portion of a bow string receiving aperture in the archery sight to prevent lower portions of the front and back members proximate to the sight aperture from separating when a lower securing screw opposite the sight aperture is tightened.
SUMMARY OF THE INVENTION
A principal object of the present invention is to provide a hinged archery sight that attaches to an outer portion of a bowstring, and that maintains contact between an archer's line of sight and a target. A feature of the archery sight is front and back portions that are detachably secured about an outer portion of a bowstring. An advantage of the archery sight is that the sight maintains a predetermined position upon the bowstring without intertwinement between the sight and the bowstring. Another advantage of the archery sight is that it maintains contact between an archer's line of sight and a target, irrespective of bowstring stretch and sight twist.
Another principal object of the present invention is to provide a hinged archery sight that promotes pivotal separation of front and back portions of the sight. A feature of the device is a hinge insertion portion that is manually urged into a hinge receiving portion. An advantage of the hinged archery sight is that a portion of the sight “opens” to receive a bowstring. Another advantage of the hinged archery sight is that the sight provides “automatic” alignment between cooperating fastener apertures in the front and back portions when the front and back portions are manually urged together, thereby allowing the archer to manually secure the front and back portions together without the archer having to visually align the cooperating fastener apertures.
Another principal object of the present invention is to maintain pivotal engagement between the hinge insertion portion and the hinge receiving portion irrespective of the position of the hinge insertion portion relative to the hinge receiving portion. A feature of the hinged archery sight is a section of the hinge insertion portion being “force fit” into a cooperating aperture in the hinge receiving portion. An advantage of the hinged archery sight is that no extrinsic elements are required to pivotally secure the hinge insertion portion to the hinge receiving portion.
Another object of the present invention is to minimize wobble of the hinged archery sight after an arrow is shot from the bow. A feature of the archery sight is a center of gravity that is maintained in alignment with the bowstring irrespective of the bowstring stretching with use. An advantage of the device is that the bowstring stretching does not degrade the accuracy of archery sight when aligning an archer's line of sight with a target, irrespective of the archery sight being secured to an outer portion of the bowstring, or being intertwined with the bowstring.
Yet another object of the present invention is to minimize the mass of the archery sight. A feature of the archery sight is a relatively light weight material for fabricating the sight. Another feature of the archery sight is relatively small dimensions for all portions of the sight. An advantage of the sight is that the wobble of the archery sight is minimized after an arrow is shot from the bow.
Still another object of the present invention is to provide a hinged archery sight that can be used for both “right handed” and “left handed” archers. A feature of the hinged archery sight is an oval aperture having a relatively long longitudinal dimension relative to a lateral dimension of the oval aperture. Another feature of the hinged archery sight is an oval aperture having a relatively long longitudinal dimension relative to a longitudinal dimension of the hinged archery sight. An advantage of the hinged archery sight is that the hinged archery sight can be disposed upon a bowstring such that the sight aperture is disposed on the left side of the bowstring relative to the archer for a right handed archer (archer holds the bow with the left hand, draws back the bowstring with the right hand), and such that the sight aperture is disposed on the right side of the bowstring relative to the archer for a left handed archer (archer holds the bow with the right hand, draws back the bowstring with the left hand).
Another object of the present invention is to maintain a predetermined position of the archery sight upon the bow string, irrespective of vibration forces generated by the bow string when shooting an arrow. A feature of the archery sight is at least one pointed projection or “spike” being integrally joined to a lower portion of a recess wall in the front member such that the spike radially penetrates the bow string when front and back members are secured together about the bow string. Another feature of the archery sight is at least one pointed projection or spike being integrally joined to an upper portion of a recess wall in the back member such that the spike radially penetrates the bow string when front and back member are secured together about the bow string. An advantage of the archery sight is that an archer does not have to readjust the predetermined optimum position of the hinged archery sight upon the bow string when multiple arrows are shot from the bow string.
Another object of the present invention is to prevent lower portions of front and back members of a hinged archery sight from separating when a hinged archery sight is configured with a relatively large sight aperture opposite a lower securing screw with the bow string disposed between the sight aperture and the lower securing screw. A feature of the hinged archery sight is an enlarged lower end portion of a bowstring aperture disposed between the lower securing screw and the sight aperture. An advantage of the hinged archery sight is that less front and back member separation force is generated when lower portions of the front and back members engage the bow string, resulting in lower portions of front and back members proximate to the sight aperture not separating, thereby reducing accelerated degradation of the tensile force tolerated by the bow string when the bow string is drawn by an archer. Another advantage of the hinged archery sight is that by increasing the diameter dimension of the lower portion of the bow string aperture, the surface area of the front and back members proximate to the sight aperture can be reduced because there is no need for a second lower securing screw to be inserted through the front and back members at a location opposite a lower securing screw beneath a hinge portion of the archery sight. Another advantage of the hinged archery sight is that the reduced surface area for the front and back members reduces the weight of the hinged archery sight and correspondingly reduced degradation of the surface of the bow string upon which the archer sight is secured.
Briefly, the invention provides a hinged archery sight for a bow for shooting arrows that includes a hinge portion for pivotally securing a front member of the hinged archery sight to a back member of the hinged archery sight. The hinged portion is disposed proximate to an upper first side portion of said hinged archery sight. The invention further provides a sight portion disposed proximate to a lower second side portion of the hinged archery sight and a bow string aperture for receiving a bow string. The bow string aperture is formed by a recess in a back wall of the front member longitudinally aligned with a cooperating recess in a front wall of the back member. The bow string aperture is disposed between the hinge portion and an upper fastener disposed proximate to an upper second side portion of the hinged archery sight. The bow string aperture is also disposed between the sight portion and a lower fastener disposed proximate to a lower first side portion of the hinged archery sight. The invention also provides at least one pointed projection integrally joined to an arcuate wall of the recess in the back wall of the front member, and at least one pointed projection integrally joined to an arcuate wall of the recess in the front wall of the back member; whereby, the hinged archery sight is maintained at an optimum position upon a bow string irrespective of vibrations generated by the bow string when shooting an arrow.
Further, the invention provides a hinged archery sight detachably secured to a bow string that includes a hinge portion for pivotally securing a front member of the hinged archery sight to a back member of the hinged archery sight, the hinge portion being disposed proximate to an upper first side portion of the hinged archery sight, and a sight portion disposed proximate to a lower second side portion of the hinged archery sight. The invention further provides a bow string aperture for receiving a bow string. The bow string aperture is formed by a recess in a back wall of the front member. The back wall recess is longitudinally aligned with a cooperating recess in a front wall of the back member and the bow string aperture is disposed between the hinge portion and an upper fastener disposed proximate to an upper second side portion of the hinged archery sight. The bow string aperture is also disposed between the sight portion and a lower fastener disposed proximate to a lower first side portion of the hinged archery sight. The invention also provides an enlarged bottom end portion having a diameter substantially the same as the diameter of the bow string; whereby, the enlarged bottom end portion of the bow string aperture reduces frictional degradation of the front and back members, and reduces erosion of engaging surfaces of the archery sight and the bow string, while maintaining an optimum predetermined position for the archery sight upon the bow string.
Also, the invention provides an a hinged archery sight for a bow for shooting arrows that includes a hinge portion for pivotally securing a front member of the hinged archery sight to a back member of the hinged archery sight with the hinge portion being disposed proximate to an upper first side portion of the hinged archery sight. The invention further provides a sight portion disposed proximate to a lower second side portion of the hinged archery sight and a bow string aperture for receiving a bow string. The bow string aperture is formed by a recess in a back wall of the front member, the back wall recess being longitudinally aligned with a cooperating recess in a front wall of said back member. The bow string aperture is disposed between the hinged portion and an upper fastener disposed proximate to an upper second side portion of the hinged archery sight. The bow string aperture is also disposed between the sight portion and a lower fastener disposed proximate to a lower first side portion of the hinged archery sight. The invention also provides at least one pointed projection integrally joined to an arcuate wall of the bow string aperture such that the pointed projection ultimately penetrates the bow string when the front and back members are secured to the bow string; whereby, the hinged archery sight is maintained at an optimum position upon a bow string irrespective of moderate vibrations generated by the bow string when shooting an arrow.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to FIGS. 1-21, a hinged embodiment for an archery sight for a bow for shooting arrows in accordance with the present invention is denoted by numeral 400. The hinged archery sight 400 is fabricated from a relatively rigid, light weight plastic and includes a lower protuberance 401, front and back members 402 and 404 that, when secured together, form a hinged portion 406 at an upper right portion of the sight 400, and a sight portion 408 with sight aperture 398 at a lower left portion of the archery sight 400. A preferred embodiment of the archery sight 400 is its relatively small size and weight that enable the sight 400 to maintain a predetermined position upon a bowstring 403 via two screws 409 and cooperating nuts 411 diagonally disposed on opposite sides of the bow string 403.
The preferred dimensions for the hinged archery sight 400 include a longitudinal dimension of substantially about three-fourths of an inch, a maximum lateral dimension of substantially about five-eighths of an inch, and a maximum “thickness” of substantially about one-eighth of an inch. The weight of the hinged archery sight 400 is substantially about one gram. Although the aforementioned dimensions and weight are preferred for the hinged archery sight 400, dimensions and weights less and greater than those provided can be used for the sight 400 without degrading the performance of the sight 400 or the bow string 403 to which the sight 400 is secured. The configuration, dimensions and weight of the hinged archery sight 400 allows the sight 400 to be used for “right handed” archers (sight portion 408 on left side of bow string 403) and “left handed” archers (sight portion 408 on right side of bow string 403 (not depicted)).
The front member 402 includes front and back substantially planar walls 410 and 412, a longitudinal ridge portion 405 that provides a corresponding longitudinal recess 407, which may include a knurled surface for better “gripping” the string 403, in the back wall 412 that snugly receives the bow string 403, an oval configured sight aperture 414 formed via oval side wall 427 that is perpendicular to the front wall 410 of the front member 402 and a front wall 444 of the back member 404, when taking a front elevation view of the front member 402 (FIG. 5), a hinge insertion portion 416, and first and second funnel configured fastener receiving apertures 418 and 420 for receiving flathead screws 409 to maintain a co-planar surface with the front wall 410. The ridge portion 405 includes a relatively planar peak that is parallel with a longitudinal central axis of the sight 400. The longitudinal central axis is aligned with a center of gravity of the sight 400. The planar peak of the ridge portion 405 is elevated a relatively small distance above the front wall 410. The oval sight aperture 414 includes a longitudinal dimension extending between upper and lower arcuate points 422 and 424, and a lateral dimension extending between midpoints 426 of parallel walls 428. The preferred longitudinal dimension is substantially about four-tenths of an inch, or double the lateral preferred dimension of two-tenths of an inch.
The back member 404 includes front and back substantially planar walls 444 and 450, a longitudinal ridge portion 405a that provides a corresponding longitudinal recess 407a, which may include a knurled surface for better gripping the string 403, in the back wall 450 that snugly receives the bow string 403, an oval configured sight aperture 414a formed via oval side wall 427a perpendicular to the front wall 410 of the front portion 402 and the front wall 444 of the back member 404, when taking a front elevation view of the back member 404 (FIG. 10), a hinge receiving portion 442, and first and second fastener receiving apertures 418a and 420a that include retaining walls 413 perpendicular to and secured to the back wall 450 to prevent the nuts 411 from rotating when receiving rotating screws 409 that secure the front portion 402 to the back portion 404. The ridge portion 405a includes a relatively planar peak that is parallel with a longitudinal central axis of the sight 400. The longitudinal central axis is aligned with a center of gravity of the sight 400. The planar peak of the ridge portion 405a is elevated a relatively small distance above the front wall 444.
The oval sight aperture 414a includes a longitudinal dimension extending between upper and lower arcuate points 422a and 424a, and a lateral dimension extending between midpoints 426a of parallel walls 428a. The preferred longitudinal dimension is substantially about four-tenths of an inch, or double the lateral preferred dimension of two-tenths of an inch. Except for the hinge receiving portion 414a and the nut retaining walls 413, the front wall 410 of the front member 402 is substantially a congruent mirror image of the back wall 450 of the back member 404. Except for the hinge receiving portion 442; and locking pegs 466 integrally joined to the back wall of the front member 402, and locking peg receiving recesses 468 in the front wall 444 of the back member 404, the back wall 412 of the front member 402 is substantially a mirror image of the front wall 444 of the back member 404.
The configuration, dimensions and light weight of the hinged archery sight 400 allows the sight 400 to be used for “right handed” archers (sight aperture 398 on the left side of the bow string 403 when the bow is vertically positioned) or “left handed” archers (sight aperture 398 on the right side of the bow string 403 when the bow is vertically positioned). Further, the configuration and dimensions of the hinged archery sight 400 promotes an oval sight aperture 398 configuration when the sight 400 is secured to a bow string 403 disposed in a substantially vertical position, and a substantially circular or annular sight aperture 398 configuration when the sight is secured to a bow string 403 manually drawn toward the user to an angular position that is substantially about thirty-two to thirty-three degrees as depicted in FIGS. 13, 16 and 21.
Referring to FIGS. 5-8, and 14), the hinge insertion portion 416 includes, when taking a front elevation view of the front member 402, a rectangular configured inner section 430 integrally joined to a rectangular configured outer section 432. The inner section 430 is integrally joined to a first longitudinal wall 417 of the ridge portion 405, such that a front planar wall 434 of the inner section 430 is coplanar with the front wall 410 of the front member 402, and a back inclined planar wall 436 of the inner section 430 angularly extends from the first longitudinal wall 417 and distally from the back wall 412 of the front member 402 to form a back planar wall 425 of the outer section 432. Further, the inner section 430 includes lateral side walls 423 that are perpendicular to the first wall 417 of the ridge portion 405; and a longitudinal side wall 421 that is parallel to the first wall 417 of the ridge portion 405, the side wall 421 also being perpendicular to a top wall 438 of the outer section 432. The longitudinal side wall 421 and the back inclined wall 436 of the inner section 430 cooperate to offset the outer section 432 from the inner section 430 such that a front wall 438 of the outer section 432 is coplanar with the back wall 412 of the front member 402 to enable the outer section 432 to angularly insert (see FIGS. 14 and 15) into a hinge receiving aperture 439 in the back member 404, thereby allowing the front and back members 402 and 404 to be manually urged from an initial angled orientation to a position where the back wall 412 of the front member 402 engages a front wall 444 of the back member 404 to form the hinged bow sight 400.
As the outer section 432 is angularly inserted into the hinge receiving aperture 439, the top wall 438 of the outer section 432 ultimately engages an edge portion 441 of a bottom wall 440 of a hinge receiving portion 442 integrally joined to the front wall 444 of the back member 404. The hinge receiving portion 442 is configured such that side walls 462 elevate the bottom wall 440 a relatively short distance above the front wall 444 of the back member 404, thereby allowing the outer section 432 to angularly and snugly slide under and engages the edge portion 441 of the bottom wall 440 while the back wall 412 of the front member 402 is manually urged toward the front wall 444 of the back member 404, and the top wall 438 of the outer section 432 is manually urged toward the bottom wall 440 of the hinge receiving portion 442.
Ultimately, the back wall 412 congruently engages cooperating portions of the front wall 444, resulting in the top wall 434 of the inner section 430 being co-planar with a top wall 446 of the hinge receiving portion 442; the bottom wall 436 of the inner section 430 engaging the front wall 444 of the back member 404; and substantially all of the top wall 438 of the outer section 432 engaging all of the bottom wall 440 of the hinge receiving portion 442, thereby providing a relatively small gap 447 between the side wall 421 of the inner section 430 and a side wall 451 of the hinge receiving portion 442.
Further, when the back wall 412 congruently engages cooperating portions of the front wall 444, a bottom wall 448 of the outer section 432 becomes co-planar with a back planar wall 450 of the back member 404; and an end wall 452 of the outer section 432 becomes co-planar with a side wall portion 454 of the back member 404 and an outer side wall 456 of the hinge receiving portion 442.
The gap 447 between the side wall 421 of the inner section 430 and the side wall 451 of the hinge receiving portion 442, and the engagement of the top wall 438 of the outer section 432 with the edge portion 441 of the bottom wall 440 of the hinge receiving portion 442, promote a pivoting action between the side walls 460 of the outer section 432 and the cooperating aperture side walls 462 of the hinge receiving portion 442. The pivoting action is achieved via a force fit relationship between the side walls 460 of the outer section 432 and the aperture side walls 462 of the hinge receiving portion 442 due to a relatively larger distance separating the side walls 460 of the outer section 432 in comparison to the distance separating the aperture side walls 462. The respective side walls 460 and 462 maintain engagement and promote a pivoting motion during angular separation of the front and back members 402 and 404 to positions that allow the bow string 403 to be inserted into the bow string recess 407a in the back member 404; whereupon, the front and back members 402 and 404 are secured together via fasteners and nuts 409 and 411, and locking pegs 466 integrally joined to and extending from the back wall 412 of the front member 402, and diagonally disposed adjacent to respective arcuate portions of the oval sight aperture 414. The locking pegs 466 are configured and dimensioned to snugly insert into cooperating locking peg receiving recesses 468 in the front wall 444 of the back member 404.
In operation, an outer section 432 of a hinge insertion portion 416 of a front member 402 of hinged archery sight 400 is manually and angularly inserted into a hinge receiving aperture 439 in a hinge receiving portion 442 of a back member 404 of a hinged archery sight 400 for a bow string 403 for shooting arrows. After the outer section 432 is angularly inserted into the receiving aperture 439, the angular position of the front member 402 relative to the back member 404 is maintained via the relatively greater dimension of an end wall 452 of the outer section 432 being manually forced into a smaller distance of separation between aperture side walls 462 of the hinge receiving portion 442. The user of the hinged bow sight 400 is then able to hold the sight 400 with one hand and position the sight 400 such that the bow string 403 is disposed between the front and back members 402 and 404. The user then urges the front and back members 402 and 404 together via the outer section 432 of the insertion portion 416 cooperating with the side walls 462 of the receiving portion 442 to provide a pivoting motion between the front and back members 402 and 404, until the top wall 438 of the outer section 432 is disposed in substantial planar engagement with the bottom wall 440 of the receiving portion 442, thereby forming the hinged portion 406 of the sight 400.
As the front and back members 402 and 404 are manually urged together, the bow string 403, generally about one-tenth of an inch in diameter, is snugly received by and secured in the joined bow string recesses 407 and 407a, which form a bow string aperture 470 having a diameter substantially about 0.08 inches, that ultimately crimps the bow string 403 between the recesses 407 and 407a without damaging the string 403. The two screws 409 are then rotationally inserted into cooperating nuts 411 and the locking pegs 466 snugly inserted into cooperating peg recesses 468 until the bow sight 400 is secured to the bow string 403, such that the sight 400 can be manually slid upon the bow string 403 to a position that optimizes the sight 400 accuracy for the respective user. The screws 409 are then tightened such that the sight 400 maintains its optimum position upon the string 403, irrespective of the string 403 vibrations generated when an arrow is “fired” from the bow by the user. In the event that the sight 400 needs to be repositioned upon the bow string 403, the user need only loosen the screws 409 sufficiently to allow the user to slide the sight 400 upon the string 403 to a new position selected by the user.
Referring now to FIGS. 17-21, to maintain the accuracy of the hinged bow sight 400 when the hinged bow sight 400 is disposed in an angular position substantially less than thirty-two degrees, the oval sight aperture 398 is formed via front and back oval sight apertures 414 and 414a in respective front and back portions 402 and 404 that have been joined together. The combined oval sight apertures 414 and 414a include upper inclined walls 500 and 500a, and lower inclined walls 502 and 502a formed via upper sloping wall portion 503 and 503a, and cooperating but opposite sloping lower wall portion 505 and 505a. Further, the apertures 414 and 414a include two opposite lateral midportion walls 507 and 507a, both being perpendicular to the front walls 410 and 444, and back walls 412 and 450 of respective front and back members 402 and 404. The apertures 414 and 414a also include one upper maximum sloping or inclined wall portion 509 and 509a, respectively, and one lower maximum oppositely sloping wall portion 501 and 501a, respectively.
Both the upper maximum sloping wall portions 509 and 509a, and the oppositely maximum sloping lower wall portions 501 and 501a form respective upper and lower acute angles 515 and 517 (see FIG. 21) with the front and back walls 410 and 450. The upper maximum inclined wall portion 509 and 509a is disposed at a midportion of the upper sloping wall portion 503 and 503a, and the lower maximum inclined wall portion 501 and 501a is disposed at a midportion of the lower sloping wall portion 505 and 505a. The combined aperture sights 414 and 414a include changing slopes for the sloping wall portions 503 and 503a, and 505 and 505a, respectively, to provide sharp edges for the archer's eye to view and align the sight portion 408 with a bow sight 370 attached to a bow 372, irrespective of the bowstring drawback by the archer, thereby providing increased accuracy when shooting the arrow at a target 374.
In a preferred embodiment, the arcuate, inclined upper wall 503 and 503a begins at one of the two lateral walls 507 and 507a that are perpendicular to the front and back walls 410 and 450. The upper wall 503 and 503a then arcuately extends upward to the upper maximum sloping wall portion 509 and 509a at an inclined angle or slope that continually and proportionately is increased from the lateral wall 507 and 507a to the upper wall portion 509 and 509a, which forms an angle 515 substantially about thirty-two to thirty-three degrees with the front and back walls 410 and 450. The inclined, maximum sloping upper wall portion 509 and 509a extends from the front wall 410 to the back wall 450. The arcuate, inclined upper wall 503 and 503a then arcuately extends downward from the upper maximum sloping wall portion 509 and 509a to the other or second lateral wall 507 and 507a at an inclined angle or slope that continually and proportionately is reduced from the upper, maximum sloping wall portion 509 and 509a until lineally joining the second sidewall 507 and 507a, thereby forming a perpendicular wall portion 507 and 507a with the front and back walls 410 and 450 at only the sidewall 507 and 507a, which is at the lateral midportion of the aperture sight portion 414 and 414a. 
The slope of the inclined lower wall 505 and 505a can be in the same direction as the slope of the inclined upper wall 503 and 503a, thereby forming a “full-funnel” configuration with walls combined walls 503 and 503a, and walls 505 and 505a having varying slopes of straight line or curved configurations, however, optimum sight 414 and 414a accuracy is achieved by configuring the slope of the inclined lower wall 505 and 505a in a reverse or opposite direction to the slope of the inclined upper wall 503 and 503a. Thus, the lower wall 505 and 505a extends from the sidewall 507 and 507a to the lower, maximum sloping wall portion 501 and 501a, whereupon the lower wall portion 501 and 501a forms and angle 517 with the front and back walls 410 and 450 substantially about thirty-two to thirty-three degrees. The lower wall portion 505 and 505a then continually and proportionately extends upward from the lower wall portion 501 and 501a to the original side wall 507 and 507a such that the slope of the lower wall 505 and 505a relative to the front and back walls 410 and 450 is reduced from substantially about thirty-two to thirty-three degrees until the lower wall 505 and 505a becomes perpendicular with the front and back walls 410 and 450 at the original or first side wall 507 and 507a. The thirty-two to thirty-three degrees of angle 515 and 517 can vary more or less than the optimum specification, however, the hinged archery sight 400 accuracy will correspondingly be reduced with the variations of the degrees of the angles 515 and 517.
The hinged archery sight 400 depicted in FIGS. 1-21 is also illustrated in FIGS. 22-27. The hinged archery sight 400 in FIGS. 22-27 includes a relatively pointed projection or lower spike 552 integrally joined to an arcuate wall 554 that forms the recess 407 in the back planar wall 412 of the front member 402, thereby altering the hinged archery sight 400 such that a modified archery sight denoted by numeral 550 is formed that includes the same elements with the same identifying numbers as provided in FIGS. 1-21 in the above description. The modified hinged archery sight 550 further includes a hinge portion 540 disposed proximate to an upper first side portion 541 of the archery sight 550, a sight portion 542 disposed proximate to a lower second side portion 543 of the modified hinged archery sight 550, and an upper spike 556 integrally joined to an arcuate wall 558 that forms the recess 407a in the front planar wall 444 of the back member 404. Both lower and upper spikes 552 and 556 are orientated such that the spikes radially penetrate the bow string 403 when front and back members 402 and 404 are secured together about the bow string 403, resulting in the modified hinged archery sight 550 being “locked” into and upon the bow string 403, thereby maintaining a predetermined position for the modified sight 550 upon the bow string 403, irrespective of vibration forces generated by the bow string 403 when shooting an arrow, thereby negating an archer having to readjust a predetermined optimum position of the modified hinged archery sight 550 upon the bow string 403 when multiple arrows are shot from the bow string 403.
Although the preferred configuration for the sight aperture 398 of the modified hinged sight 550 is oval, the lower and upper spikes 552 and 556 will function the same for a sight aperture 398 having varying configurations, including but not limited to annular, elliptical and rectangular. Also, although two spikes 552 and 556 are depicted and described to secure the modified hinged archery sight 550 to the bow string 403, only one spike is required to secure the modified sight 550 upon the bow string 403 when moderate vibrations are generated by the bow string 403 when shooting an arrow; however, in the event the bow string 403 vibrations should increase to a relatively high magnitude due to a relatively “thick” bow string 403 attached to the bow 372 and/or a relatively “long” draw of the bow string 403, the sight 550 can slide upon the bow string 403 thereby requiring the user to take the time to readjust the sight to the optimum position.
Although the modified hinged archery sight 550 is depicted with only two longitudinally separated lower and upper spikes 552 and 556, multiple spikes can be integrally joined to the arcuate recess walls 554 and 558 at varying upper and lower positions to penetrate the bow string 403, thereby providing the modified sight 550 with an increased “grasp” of the bow string 403 when relatively large vibrations are generated. All spikes need to be longitudinally separated a distance that prevents adjacent spikes that penetrate the bow string 403 from damaging the bow string 403 when vibrations are generated from shooting arrows. The longitudinal distance of separation between adjacent spikes disposed upon a bow string 403 will vary depending upon the longitudinal dimension of the modified hinged archery sight 550, the bow string 403 diameter and tensile strength, and the force developed by the drawn bow upon which the bow string 403 is secured; however, the minimum longitudinal distance of separation preferred by the inventor is substantially about one-eighth of an inch.
The modified hinged archery sight 550 further includes a bow string aperture 470 having an enlarged bottom end portion 562 with a diameter substantially the same as the diameter of the bow string 407. The enlarged end portion 562 can be cylindrically configured or have a tapered configuration such that the integrally joining diameter of the bottom and upper portions 562 and 564 constantly increases as the bottom end portion 562 of the bow string aperture 470 engages the bottom end wall 566 of the modified hinged archery sight 550.
The enlarged bottom end portion 562 is required for a hinged archery sight that includes a configuration substantially similar to the hinged sights 400 and modified sight 550 because of the relatively large oval sight aperture 414. More specifically, the configuration for both archery sights 400 and 550 includes a relatively small (when compared to the oval sight aperture 414) hinge insertion portion 416 and small cooperating hinge receiving portion 442. The small size of the hinge portions 416 and 442, and the relatively large sight aperture 414, minimize the weight of the sights 400 and 550 and correspondingly minimize degradation of the bow string 403 while maintaining a center of gravity for the sights 400 and 550 in line with the bow string aperture 470. Further, the configurations of the sights 400 and 550 provide sufficient area to allow an upper screw or similar fastener 569, disposed proximate to an upper second side portion 545 of the hinged archery sight 550, to be inserted through the first and second members 402 and 404 such that the screw 569 cooperates with the hinge insertion and receiving portions 416 and 442 to “squeeze” the bow string 403 between the arcuate walls 554 and 558 of the bow string aperture 470 as the upper screw 569 is tightened, thereby securing the sights 400 and 550 to a bow string 403.
The configuration of the sights 400 and 550 include a relatively small bottom end portion 568 for both front and back members 402 and 404. The surface area of the bottom end portion 568 does not allow a fastener to be inserted through the front and back members 402 and 404 at the end portion 568, resulting in only one lower screw or similar fastener 570, disposed proximate to a lower first side portion 544 of the hinged archery sight 550, securing the bow string 403 between the front and back members 402 and 404. Without an enlarged bottom end portion 562 of the bow string aperture 470, the tightening of the lower screw 570 results in a gap (not depicted) between the back wall 412 of the front member 402 and the front wall 444 of the back member 404 at the bottom end portion 568, due to the diameter of the bow string 403 being greater than the diameter of the bow string aperture 470 that causes a “pivoting” of the front and back members 402 and 404 upon the bow string 403 as the lower screw 570 is tightened, resulting in the separation of the front and back members 402 and 404 at the bottom end portion 568. The enlarged bottom end 562 of the modified hinged archery sight 550 prevents the front and back members 402 and 404 from separating by keeping the diameters of the bottom end 562 and the bow string 403 substantially equal, thereby avoiding the pivoting action and a corresponding separation force that would otherwise separate the front and back members 402 and 404 at the bottom end portion 568. Further, the enlarged bottom end 562 reduces frictional degradation of the front and back members 402 and 404, and surface erosion of engaging portions of the modified archery sight 550 and the bow string 403, while an optimum predetermined position for the archery sight 550 upon the bow string 403 is maintained.
The foregoing description is for purposes of illustration only and is not intended to limit the scope of protection accorded this invention. The scope of protection is to be measured by the following claims, which should be interpreted as broadly as the inventive contribution permits.
