ARCHERY BOW SIGHT
A bow sight is provided including a mounting bracket including a proximal end and a distal end, a sight housing and a sight pin mounted in the housing. The proximal end can define substantially vertical slots, one above the other, to provide a first vertical adjustment of the archery bow sight. The sight housing can define another substantially vertical slot. The mounting bracket can be joined with an arm that is movable relative to the substantially vertical housing slot so that the sight housing and sight pin can be vertically adjusted up and down, moving simultaneously with one another, relative to the mounting bracket to provide a second vertical adjustment of the archery bow sight. The arm can extend from a windage adjuster mounted to the mounting bracket.
The present invention relates to archery sights, and in particular, to archery sights having a wide range of vertical movement to accommodate different shooting distances.
Most conventional archery bows are outfitted with sights that are designed to align the trajectory of an arrow shot from the bow with a target or game. These bow sights include sight pins to be aligned with the target for accurate shooting. Archers or bow hunters often desire to shoot targets or game at different distances. Accordingly, most bow sights include multiple sight pins having sight indicia aligned along a vertical axis, one over the other. Each sight indicia is calibrated for a target at a different range. Depending on the target range, the archer must select the corresponding sight pin and align its sight indicia with the target. If the archer's range estimation, pin selection and indicia alignment are correct when the archer shoots the arrow, the arrow will hit the target.
To provide a desired accuracy, a bow sight must be properly calibrated and positioned relative to a bow riser and to an arrow rest which supports an arrow. In particular, the individual sight pins and their indicia are positioned a distance from these elements to establish a desired trajectory of the arrow and its point of impact with a target. Most conventional bow sights therefore come with a vertical sight adjustment mechanism attached to an arm, which is further attached to the riser of the bow via a pair of screws through circular holes in the end of the sight arm. The vertical placement of the arm is set by those holes and their location in the arm.
The vertical adjustment mechanism is movably attached to the end of the arm and connected rigidly and immovably to a sight housing and associated sight pins. The vertical adjustment mechanism can be adjusted up or down. Many times, an archer will set up their sight pins in a specific vertical spacing for different distances, or in a particular spacing relative to the housing.
In some cases, when an archer changes arrow weights or tunes their bow differently, the sight must be adjusted vertically. In so doing, however, the archer with a conventional sight might only be able to move their sight so much with a conventional vertical adjustment mechanism. Therefore, the archer must then move all the sight pins individually to provide additional vertical sight adjustment. This can change the orientation of the pins relative to the housing, giving a less preferred sight picture to the archer. Due to the movement of the individual pins, those pins also might not be moved properly to replicate the previous spacing, in which case the pins will need to be tediously recalibrated.
Accordingly, there remains room for improvement in connection with vertical adjustment mechanisms for archery bow sights to address the positioning and orientation of sight pins relative to a housing while still providing adequate vertical adjustment of the sight as a whole.
SUMMARY OF THE INVENTIONThe aforementioned problems are overcome by a bow sight including a mounting bracket including a proximal end and a distal end, a sight housing and a sight pin mounted in the housing, wherein the proximal end can define substantially vertical slots, one above the other and optionally parallel to provide a first vertical adjustment of the archery bow sight.
In one embodiment, the slots at the proximal end can include upper and lower slots located one above the other. Respective fasteners can be placed through the slots and threaded into holes defined by a bow riser, which the slots overlap. The proximal end can thus be moved up and down relative to an infinite number of vertical settings to the preference of the user. When a setting is identified, the user can tighten the fasteners somewhere along the length of the respective slots and secure the mounting bracket to the riser in a secured manner.
In another embodiment, the sight housing can define another substantially vertical slot. The mounting bracket can be joined with an arm that is movable relative to the substantially vertical housing slot so that the sight housing and sight pin can be vertically adjusted up and down, moving simultaneously with one another, relative to the mounting bracket to provide a second vertical adjustment of the archery bow sight.
In still another embodiment, the arm can extend from a windage adjuster mounted to the mounting bracket at the distal end. The arm can be threaded, and can interface with a dial ring of the windage adjuster to laterally move the sight housing away from and toward the mounting bracket to provide a windage adjustment.
In yet another embodiment, the arm can extend to the slot of the sight housing. The arm can include a second end that engages the sight housing. The slot can be bounded by a shoulder. The second end of the arm can abut the shoulder so it is prevented from rotating relative to the housing via the abutment against the shoulder.
In even another embodiment, the sight housing slot can be defined in a planar, vertical wall of the sight housing. The vertical planar wall can transition to one or more curved walls that are disposed around the sight pin for protection of the same and to facilitate viewing of the sight pin. The planar, vertical wall can also include a portion of the shoulder adjacent the slot to engage the arm and that shoulder can prevent rotation of the sight housing relative to the arm and mounting bracket to which the arm is attached.
The bow sight of the current embodiments efficiently and easily calibrates sight pins collectively and individually for different shooting ranges. Because the mounting bracket can be moved vertically to an infinite number of positions relative to the bow riser due to the slots at the proximal end, a user can place that bracket at their preferred, precise vertical orientation relative to the riser. Further, where the sight housing is joined with the arm via another slot in the housing, the user can further adjust the sight housing, and all the pins in a gang manner, via another vertical adjustment relative to the mounting bracket. Additionally, where this other vertical adjustment is associated with an arm of the windage adjuster, the sight is simplified so that yet another secondary vertical adjuster can be eliminated from the construction on the mounting bracket, thereby reducing the complexity and assembly time of the sight.
These and other objects, advantages, and features of the invention will be more fully understood and appreciated by reference to the description of the current embodiments and the drawings.
A bow sight constructed in accordance with an embodiment of the invention is illustrated in
In particular, as shown in
In some applications, the slots can optionally include a shoulder 33. This rim can transition from the exterior flat surface 25 of the bracket 20 to a respective slot edge 34, which can be perpendicular to the surface 25. A head of a fastener F1 or F2 also can be tapered or bugle shaped so that it fits in the slots, with the angled part of the head engaging a correspondingly or similarly shape of the rim so that the outside of the head is flush or below the surface 25 when the fasteners are installed. The respective slot edges can be generally linear so that the slots and edges do not impair sliding of the mounting bracket relative to the riser when the fasteners are installed but not tightened. In this manner, via the relative sliding or movement of the mounting bracket relative to the riser, the slots can provide a first vertical adjustment of the bow sight, ultimately moving the relative position of the sight pins 70 vertically relative to the riser 100.
In particular, as shown in
Optionally, the mounting bracket 20 can include a plurality of indicia elements 28 placed at preselected spaced locations adjacent the first and third slots. These elements can be of any aesthetic configuration. As shown, they can be laser etched on the bracket. Of course, in other cases they can be notches or lines painted, coated or otherwise applied to the mounting bracket.
The mounting bracket can be secured in the respective vertical positions or at the levels by tightening the respective fasteners F1 and F2. This in turn pulls the mounting bracket 20 against the riser 100, securing it in place. Of course, when the fasteners are loosened, the heads of the fasteners prevent the bracket from detaching from the riser, while the bracket is free to slide along the shafts of those fasteners to selected vertical levels.
As shown in
As further shown in
The windage adjuster 40 optionally can include a dial ring 44 that is threadably coupled to a first end 51 of the arm. Generally, the first end 51 can be selectively movable relative to the mounting bracket to provide lateral or windage adjustments to the bow sight. For example, the dial ring can be rotated (when the clamp knob is not clamping the arm to prevent rotation) which in turn engages a threaded portion of the arm on the first end and extending toward the second end. The second end 52 can move toward or away from the adjuster and/or the mounting bracket as a result of this movement to adjust the lateral position of the sight housing as well as the associated pins.
With reference to
As shown in
The connector wall can define the second slot 62. Because the wall is vertical and planar at least in the area where the second slot is defined, it provides an exact vertical adjustment of the housing relative to the arm so that the housing only moves linearly vertically relative to the arm, mounting bracket and any associated bow riser. The second slot can be of a length optionally at least 10 mm, at least 20 mm, at least 30 mm, at least 40 mm, at least 50 mm, between 10 mm and 50 mm, inclusive, between 10 mm and 40 mm inclusive, or other lengths depending on the application.
The connector wall 64 also can form the perimeter of the second slot 62 defined in it. In particular, the connector wall can include an inner slot edge 66. The fastener F1 can be located adjacent this edge when securing the housing to the arm. The edge can transition to a shoulder 62S which can be disposed on one or both opposing sides of the slot. The shoulder can include a shoulder wall 62SW that forms a recess around the slot, the recess 62R being inset from the exterior 64E.
As shown in
As mentioned above, a second fastener F2 can extend through the slot 62 and can be joined with the second end of the arm. The fastener can include a shaft that actually extends through the slot 62, into the arm 50. A head F2H of the fastener can engage the interior surface 641 of the housing, without extending through the slot. The fastener can engage the vertical wall 64 on an opposite side of the wall from the engagement surface 56. For example, the fastener head can engage the interior surface, and the engagement surface can engage the exterior surface or parts of the recess or shoulder where optionally included. The head can engage the sight housing, for example, the connector wall 64, to press the sight housing against the engagement surface 56 and/or some portion of the arm or mounting bracket, and fix the sight housing in a fixed vertical position relative to the arm. Of course, when the fastener is loosened, the sight housing can move relative to the arm vertically, to different levels.
Generally, the arm 50 is movable relative to the substantially vertical second slot and vice versa so that the sight housing 60 and sight pins 70 can be vertically adjusted up and down, moving simultaneously with one another, relative to the mounting bracket to provide a second vertical adjustment of the archery bow sight, in addition to the first vertical adjustment noted above. An example of this second vertical adjustment is shown in comparing
The connector wall and housing in general can then be moved, with the slot and connector wall moving relative to the second fastener F2 upward, for example, to the position shown in
As mentioned above, the sight 10 can include sight pins 70, which can vary, depending on the number of ranges that the bow sight is designed to accommodate. As shown in
The sight pins can also include a second end 72, distal from the first end, which can include a sight indicia 77. This sight indicia can be any point or indicia of any type that is visually placed in line with a target for assisting in the proper aiming of the bow. Sight indicia can be of any shape, for example, circular, diamond, square, and other geometrical shapes. Moreover, the sight indicia can be formed as colored dots, the end of a light gathering filament, or simply the end of the sight pin. As shown, however, the sight indicia can be formed by the ends of fiber optic filaments, which collect light along its length, with the collected light exiting the end of the filament. The length of the fiber optic can be secured to in a conventional manner to the sight element. The end of the fiber optic filament forming the sight indicia can be located in a hole defined in the second end 72 of the element. Alternatively, the hole may be absent, and the fiber optic filament can be adhered or crimped or otherwise fastened to the second end 72 as desired. Further alternatively, the fiber optic filament can be replaced entirely with a vile, bulb or tube (not shown) containing a light emitting substance, such as tritium and/or phosphor. The tube can be secured in the hole much like the fiber optic filament to provide a sight indicia for an archer. Alternatively, the entire sight element can be constructed from light gathering and transmitting material.
Each of the sight pins can be vertically adjustable within the sight housing. For example, the connector wall can include a third slot, distal from the second slot but parallel to the second slot. Each of the sight pins 70 can be selectively slidable within the third slot 72 as shown in
Optionally, the bow sight includes a bubble level 95. This level can be used to perform a variety of tasks. For example, the level 95 can be used by the archer to confirm, calibrate or measure a third axis of the sight. When the bubble is centered in this level, this can indicate that the third axis lies in a substantially vertical plane. As used herein, substantially vertical means that the sight axis lies in a substantially vertical plane, regardless of the angle of the axis to a horizontal plane.
