Bow sighting device

[0001] 1. Field of the Invention

[0002] The present invention relates generally to sporting equipment and, more specifically, to a bow sighting device comprising a mounting bracket having a plurality of threaded apertures therethrough for mounting to a bow in a typical manner with front and rear sighting apparatus releasably attached to the mounting bracket whereby targeting adjustments can be made in addition to mounting adjustments for left or right handed users. Alternately provided is a lighting element releasably fixed approximate the rear sight pin that may incorporate a length of optical fiber.

[0003] The front-sight apparatus is composed of a sight-pin housing, housing attachable track, track mating front-sight mounting attachable to the mounting bracket, and at least one sight-pin with optical fiber within said housing. The rear-sight apparatus is composed of a mounting bracket attachable platform and a sight-pin.

[0004] All of the sight-pins have a somewhat Y-shape with the apex divergent arms extending from a semicircular base, as opposed to the typical sight pins having a V-shaped notch, which by design provides for easily aligning the semicircular pin trough with the desired pin point of optical fiber positioned within the front-sight sight-pin.

[0005] More than one optical fiber may be positioned within the front sight sight-pin and may be of different colors. Furthermore, the instant invention provides that the one or more optical fibers may extend from the back side of the front-sight sight-pin and be anchored in such a manner as to be hidden from view when using the sighting device. Alternately provided is an engageable lighting element that will illuminate the optical fibers providing pin points of light emanating from the optical fiber ends terminating in the front side of the sight-pin. The rear sight sight-pin may also have one or more optical fibers having terminal ends on the front side of the pin which can be illuminated from a selectively engageable lighting element.

[0006] It is further envisioned that the sight-pin itself may incorporate a selectively engageable lighting element in communication with optical fibers having a terminus on the front side of the sight-pin. Alternately provide for with this configuration is a movable gateway positioned between the bulb and fibers for selectively illuminating one or more of the optical fibers.

[0012] A range finder and bow sight device wherein plural sights are made adjustable and correlated with a fixed, stepped range finder. The individual bow sights used are adjustable both for height and azimuth, and in a preferred form of the invention, can be locked through such adjustment to a vertical slide member. Mounts on the device are self-aligning and can be screwed or taped to a conventional archery bow.

[0013] The device includes an elongated body in the form of a metal strip that is secured to one side of an archery bow. At the rear end of the body there is a laterally extending arm on which is mounted a rotatable disc having a number of sight openings therein, the sight openings being at differing distances from the disc's axis of rotation. Detent means assures that whatever sight opening is selected remains in position, yet readily permits another sight opening to be selected for a different shooting range. At the front end of the elongated body is another laterally extending arm, this arm having a plurality of vertically oriented threaded apertures into any one of which can be threaded a pin provided with a bead or ball on its upper end. By properly selecting the particular sighting opening at the rear and by properly adjusting the height of the bead or ball at the front, the bowman is able to control quite accurately the course of the arrow.

[0014] An archery sighting device which includes an elongated sight bracket fixedly attached to the bow above the hand grip portion. A horizontally disposed tab at the rear of the sight bracket has a “V” notch coplanar with the plane formed by the extended bow string and defines a central sighting point intermediate the bow and the relaxed position of the bow string. A plurality of pin sights are disposed at the front end of the sight bracket which define the forward sight point. The plurality of pin sights individually designate preselected shooting distances. The bow string in its extended or drawn position is the third sighting point. Sighting is achieved by the coplanar alignment of the extended bow string with the inverted apex of the “V” notch and the sight pin representing the desired shooting distances.

[0015] An archery bow sight includes a plate arranged for removable attachment to the handle portion of an archery bow and supporting a longitudinally extendable mounting arm which mounts at its forward end a horizontally extending support to which a vertically elongated sight bar is mounted for horizontal windage adjustment. The sight bar mounts a plurality of sight pin blocks by means of interconnecting dovetail components, the blocks extending transversely across the sight bar for adjustment along the length of the sight bar. An elongated threaded sight pin member extends adjustably through a threaded bore in each block in the transverse direction of the sight bar, and a slot intercepts the dovetail component and sight pin bore in the block. A clamp screw in the block extends across the slot and operates upon rotation in one direction to clamp the block to the sight bar and the sight pin to the block.

[0016] A sighting device for use with an archery bow, comprising a mounting plate mountable on the bow; an elongated support track attached to the mounting plate; at least one blade-like sight element connected generally perpendicular to the support track, the blade-like element being oriented edge-wise relative to the line of sight of the archer, a light emitting diode attached to the blade-like element along the edge thereof facing the archer, the light emitting diode being electrically connectable to an electrical power source; switch means controlling activation of the light emitting diode by the electrical power source; means for manually adjusting the light emitting diode vertically and horizontally, and draw indicator means indicating the position of an arrow used with the bow, the draw indicator means being operative to switch the switch means to activate the light emitting diode when the arrow is at a predetermined position.

[0017] An archery sight for use with a bow has one or more adjustable beaded sighting pins extending vertically, parallel to the bow frame. A notched sighting plate is mounted remote from the pins with the notches aligned with the pins in the sighting direction.

[0018] An archery bow sight apparatus having a sight bar with at least one front sight that is adjustable to a fixed position relative to the sight bar, and a rear sight that is independently pivotal to maintain a vertical alignment with the ground, which combination of fixed and pivotal sights provide an archer with an improved sight means for greater accuracy in clustering his arrows in a target.

[0019] An archery bow including a bow speed specific sight pin block having sight pin openings for sight pins located therein relative to each other at fixed distances for a given bow speed, so that when a single sight pin is manually positioned to indicate its corresponding arrow flight range, each of the other sight pins in the other openings will be in position to indicate their corresponding arrow flight range. The sight pin block may be mounted in a riser opening and allen screws may be included in the bowsight pin block frame for moving wedges located in the bowsight pin block frame into engagement with a sidewall of the riser opening for mounting the bowsight pin block in the riser opening.

[0020] An archery combination involving an archery bow and a bow sight. The bow sight uses a brace secured to the bow with at least two sighting pins which extend at right angles to the archer's line of sighting. A protective guard is secured to the brace and, is moveable between a protective position around the sighting pins to a position which exposes the pins. When the protective guard is in position to expose the sighting pins, the pins are released or “unlocked” from the brace allowing the sighting pins to be easily removed from the brace for repositioning; when the protective guard is in the protective position, the pins are “locked” and cannot be removed from the bow sight.

[0021] A sighting device (19) for an archery bow comprises an adjusting scale mounted by means of rods 9 on a block 8 to which is pivotally mounted a sighting bar 12 carrying, at its free end, a laterally adjustable sight pin assembly 22, and where it contacts the scale, a locking screw 29. The sighting device is detachably mounted, mounted by means of locating lugs 15, 16, into sockets 13 and 14 of block 7 which is permanently attached to the back (i.e. side facing the target) of the bow. A pointer 30 attached to the sighting arm is arranged to indicate scale readings.

[0022] The present invention includes an arrow guide and bow sight adaptable to right-handed or left-handed archery bows. The arrow guide including a vertical support wheel with a V-shaped groove running along its circumference in which an arrow may rest when shooting. This wheel is designed to spin freely on a support rod, reducing friction imparted to the arrow shaft, thus increasing the accuracy, speed, and power of the archer's shot. For lateral support, two horizontal wheels are positioned to either side of the vertical support wheel to prevent the arrow from falling off of the vertical support wheel when the bow is jarred or when the bow string is quickly drawn back. Also connected to the arrow guide device is a sighting device comprising a multiplicity of sight pins and a vertical cross-hair. The sight pins are vertically adjustable to be calibrated to assorted ranges, and both the pins and the cross-hair are horizontally adjustable to account for windage.
