DESCRIPTION OF THE PREFERRED EMBODIMENT

(16) A dual bow sighting apparatus according to a preferred embodiment of the present invention will now be described in detail with reference to FIGS. 1a to 6 of the accompanying drawings. The bow sighting device 10 includes a mounting member 20, an upper sight assembly 40, a lower sight assembly 60, and an elevation adjustment assembly 70.

(17) The bow sighting apparatus 10 includes a mounting member 20 configured for attachment of the apparatus 10 to an archery bow (not shown), also referred to as a compound bow or a hunting bow. The mounting member 20 may also be called a body member as it is the primary structure to which the upper and lower sight assemblies 40, 60 are attached and extend away from. The mounting member 20 may include a front end 22 and an opposed rear end 24, an interior side 30, and an opposed exterior side 32. The mounting member 20 may also define a plurality of spaced apart mounting holes 34 by which the mounting member 20 may be attached to the bow, such as with screws, pins, or other suitable fasteners. In addition, the mounting member 20 may define at least one aperture 36 that enhances the grip of an operator in gripping the mounting member 20, such as with the operator's fingers in the manner of a handle.

(18) The upper sight assembly 40 is operatively coupled to the mounting member 20 proximate an upper end 26 and rear end 24 thereof (FIGS. 1a and 1b). The upper sight assembly 40 includes an upper frame section 42 and a pendulum sight 50 pivotally coupled to a rod 44 situated adjacent an upper end 26 of the upper frame section 42, the pendulum sight 50 being described in more detail later. The upper sight assembly 40 is mounted at a predetermined or fixed elevation position—at least during use of the bow sight apparatus 10. In other words, the upper frame section 42 may include a plurality of upper elevation fasteners 46 that may be set during targeting setup prior to a hunting event but not during hunting.

(19) Similarly, the lower sight assembly 60 is operatively coupled to the mounting member 20 proximate a lower end 28 and rear end 24 thereof. The lower sight assembly 60 includes a lower frame section 62 and includes a vertical sight pin 69 extending upwardly from the lower frame section 62 and will be described further later. Further, the lower sight assembly 60 is initially mounted at a predetermined or fixed elevation position. As described above, the lower frame section 62 may include a plurality of lower elevation fasteners 64 that may be set during targeting setup prior to a hunting event. Unlike the upper sight assembly 40 described above, however, the lower sight assembly 60 is movable upwardly or downwardly during use, e.g. while hunting, by operation of the elevation adjustment assembly 70. It is understood that the lower sight assembly 60 is always separate from the upper sight assembly 40 although the degree and distance of that separation is adjustable via the elevation adjustment assembly 70 described below. Preferably, the mounting member 20 is perpendicular to the upper and lower sight assemblies so that when the mounting member 20 is attached to an archery bow (not shown), the sight assemblies being properly positioned for use as sighting tools for the hunter holding the bow.

(20) In general, the elevation adjustment assembly 70 includes a linkage 76 pivotally coupled to the mounting member 20 and in communication with the lower sight assembly 60, the linkage having a proximal end 72 and opposed distal end 74. Operation of the linkage 76 causes the lower sight assembly 60 to move closer to or further away from the upper sight assembly 40, i.e. to increase or decrease a distance between the two assemblies. The linkage 76 has a linear configuration and is pivotally coupled the exterior side 32 of the mounting member 20 at a fulcrum 78 about midway between opposed proximal 72 and distal 74 ends thereof. The linkage 76 includes an elevation selector lever 78 adjacent the proximal end 72 configured to enable a user to operate the linkage 76. Upward or downward movement of the elevation selector lever 78 by a user causes the lower sight assembly 60 to move in an inverse direction and amount.

(21) A locking assembly 77 is coupled both to the elevation selection lever 78 and to the mounting member and is operable between an actuated (i.e. tightened) configuration that prevents movement of the elevation selection lever 78 and an unactuated (i.e. loosened) configuration allowing movement of the elevation selection lever 78. More particularly, the mounting member 20 defines a first slot 37 adjacent the rear end 24 having a substantially vertical configuration. Correspondingly, the locking assembly 77 may include a first locking fastener 80 in communication with one side of the elevation selection lever 78 and is situated in the first slot 37, the first locking fastener 80 moving upwardly or downwardly in the first slot 37 as the elevation selection lever 78 is moved by a user. Further, the locking assembly 77 may include a second locking fastener 82 in communication with a side of the elevation selection lever 78 opposite the first locking fastener 80 and configured for rotational movement between tightened and loosened configurations preventing or allowing movement of the elevation selection lever 78, respectively. It is understood that the locking fasteners essentially sandwich the lever relative to the mounting member 20. The second locking fastener 82 is illustrated as a rotating knob but may also be a wing nut or other suitable fastener.

(22) Similarly, the mounting member 20 may define a second slot 38—this one situated adjacent a rear end 24 of the mounting member 20 and also having a generally vertical orientation. Frame structures of the lower sight assembly 60 coupled to the distal end 74 of the linkage 76 are positioned to move upwardly and downwardly in the second slot 38 in an inverse direction of movement in the first slot 37.

(23) In a related aspect, an elevation scale 39 is imprinted or adhered to an outer surface of the mounting member 20 proximate the elevation selection lever 78. Further, the elevation selection lever 78 may include an indicator pin 78a extending away from the proximal end 72 and proximate the elevation scale 39. The elevation scale 39 may include numerical markings to aid a user in adjusting the elevation selection lever 78 and, as a result, adjusting the lower sight assembly 60.

(24) Now with further reference to the pendulum sight 50, the upper end 26 of the pendulum sight 50 is pivotally or rotatably mounted to the mounting rod 40 so that the pendulum sight 50 remains level even if the archery bow is tilted forwardly or rearwardly while aiming a shot, as illustrated in FIGS. 4b and 5b. In addition, a sleeve 52 may be mounted about the rod 44 so as to not allow the pendulum sight 50 to slide laterally along the mounting rod 44. And, a lock screw 54 may be in communication with the upper end 26 of the pendulum sight 50 so that, when tightened, the pendulum sight 50 cannot rotate at all. This is useful when the bow sighting apparatus 10 is being transported or mounted, i.e. to prevent damage thereto.

(25) A fiber optic ring 55 is coupled to the upper end 26 of the pendulum sight 50 and extends downwardly therefrom. In an embodiment, the fiber optic ring 55 may include a glass, plastic, or otherwise transparent construction that is hollow and in which a fiber optic cable or other material capable of absorbing ambient light may be situated. Further, a fiber optic sight rod 56 extends downwardly away from the fiber optic ring 55, the free end of which (i.e. a fiber optic sight tip 57) acts as the sight tip a hunter positions on his target. It is understood that the fiber optic ring 55, sight rod 56, and sight tip 57 are configured to absorb ambient light and, as a result, to emit a glowing light for a period of time thereafter. In an embodiment, the upper frame section 42 itself may having a transparent configuration and include an embedded fiber optic element. The fiber optics of the upper sight assembly 40 are of a first color, such as a green color.

(26) In addition, the pendulum sight 50 may include a weight 53 positioned adjacent the fiber optic ring 55, the weight causing gravity to always pull the pendulum sight 50 downwardly into a perfectly vertical position even if the mounting member 20 and upper and lower sight assemblies are tilted forwardly or rearwardly (FIGS. 4b and 5b). In addition, the upper frame section 42 of the upper sight assembly 40 may includes a horizontal upper spirit level 58 to enable a user to visually observe if he is holding the archery bow and, as a result, the bow sighting apparatus 10 in a horizontally level position during use. Similarly, the lower frame section 62 of the lower sight assembly 60 may includes a horizontal lower spirit level 66.

(27) Similarly, the lower sight assembly 60 may include fiber optic components as well. More particularly, the lower frame section 62 may include a transparent construction and include a fiber optic element 68. Further, the vertical sight pin 69 may include a fiber optic construction capable of absorbing ambient light and, as a result, emitting a glow. In an embodiment, the fiber optics of the lower sight assembly 60 are of a second color, such as orange, different from the first color exhibited by the fiber optics of the upper sight assembly 40.

(28) In another aspect, the bow sighting apparatus 10 includes a black light device 90 coupled to the mounting member 20 and situated to direct a black light in the direction of the fiber optic elements described above. More particularly, the black light device 90 is positioned to direct light at the fiber optic ring 55, sight rod 56, and sight tip 57. Likewise, the black light device 90 is positioned to direct light toward the vertical sight pin 69 of the lower sight assembly 60.

(29) Preferably, the lower frame section 62 of the lower sight assembly 60 has a generally U-shaped configuration while the upper frame section 42 of the upper sight assembly 40 has a generally inverted U-shaped configuration although more gentle general convex and concave configurations or even rectangular configurations may also work.

(30) In still another aspect, the lower frame section 62 is slidably movable laterally to selected configurations closer to the mounting member 20 or further away from the mounting member 20. Similarly, the upper frame section 42 is slidably movable laterally to selected configurations closer to the mounting member 20 or further away from the mounting member 20. Scale indicia 94, 95 may be imprinted on respective mounting arms 90, 92 to aid a user in appropriately making lateral sight adjustments. It is understood that rotational mounting and locking fasteners substantially similar to those described above relative to the elevation adjustment assembly 70 may be used to facilitate respective lateral adjustments.

(31) In use, the dual bow sighting apparatus 10 may be sighted in prior to engaging in actual hunting. For instance, the bow sighting apparatus 10 may be mounted to a bow and shots with arrows may be taken toward a target. The elevation settings of the sight assemblies, lateral adjustments, and the like may be adjusted as described above. When ready to hunt, which may be before dawn, the black light device 90 may be energized to emit light to the fiber optic elements so they will glow when needed (in darkened conditions). It is understood that the lower sight assembly 60 must be adjusted to be immediately adjacent the upper sight assembly 40 in order for all the fiber optic elements to receive the black light. Once the sun comes up, of course, ambient light will be absorbed by the fiber optic elements.

(32) Then, when hunting, the upper sight assembly 40 is already in a preset condition to be used accurately by a hunter for a shot of, say, 1 to 30 yards. But, if a target animal is, say, 30 to 50 yards away, the lower sight assembly 60 needs to be set and used. The elevation may be set by a user's operation of the elevation selection lever 78 and linkage 76 and by observing the elevation scale 39 as described above. Now, the hunter uses the tip of the vertical sight pin 69 of the lower sight assembly 60 to properly target the animal before firing an arrow.

(33) It is understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
