This invention relates generally to archery sights for archery bows, firearms, or other projectile launching devices, and more particularly to an archery sight having sight pins that can be automatically adjusted.
Archery sights typically have a plurality of sight pins associated with different distances to a target. Since bows, crossbows, or the like have different pull forces, and since arrows, bolts, and so on have different weights, it often becomes time consuming for an archer to install a new archery sight on the archery equipment and tune in each sight pin for each target distance in accordance with the particular parameters of the archery equipment. Although the prior art has offered various solutions for simultaneously adjusting several sight pins based on draw weight, arrow weight, draw length, and so on, such devices are typically cumbersome, require a large amount of separate parts, resulting in high costs passed on to the consumer. In addition, prior art archery sights with gang adjustment features can be complicated to use, often requiring a learning curve to adjust properly, thereby defeating the very purpose of such solutions, namely saving the archer time when calibrating a new archery sight or when calibrating the archery sight for a different draw weight, arrow weight, and so on.
It would therefore be desirable to provide an archery sight that overcomes one or more disadvantages of the prior art.
BRIEF SUMMARY OF THE INVENTIONIn accordance with one aspect of the invention, an archery sight for use with archery bows having different draw weights is provided. The archery sight includes a plurality of sight pins for demarcating a respective plurality of different target distances, with at least some of the sight pins being gang adjustable for accommodating the different draw weights. An adjustment member is movable along a first direction between a first position reflective of a first draw weight and a second position reflective of a second draw weight, the adjustment member having a plurality of travel pathways, the plurality of travel pathways being operably associated with the at least some of the plurality of sight pins to move the sight pins along a second direction different from the first direction. In this manner, relative movement between the plurality of travel pathways of the adjustment member and the at least some of the sight pins causes the at least some of the sight pins to simultaneously move in a second direction different from the first direction to thereby demarcate their respective target distances for at least one of the first and second draw weights.
In accordance with a further aspect of the invention, an archery sight for use with archery bows having different draw weights includes a base portion, a sight frame portion extending from the base portion and having a sight window, a plurality of sight pin assemblies connected to the base portion, each sight pin assembly having a sight pin that extends into the sight window, each sight pin having a sight point for demarcating a different target distance from the other sight points, and an adjustment mechanism operatively associate with the plurality of sight pin assemblies for simultaneously adjusting each sight pin to its associated demarcated target distance. The adjustment mechanism includes an adjustment body movable with respect to the base member along a first direction between a first position reflective of a first draw weight and a second position reflective of a second draw weight. A plurality of guide tracks are associated with the adjustment body for each of the plurality of sight pin assemblies. With this construction, relative movement between the adjustment body and the sight pin assemblies causes the sight pins to simultaneous move along their respective guide tracks to automatically adjust the sight pins for their associated demarcated target distances and at least the first and second draw weights to thereby simultaneously gang adjust at least some of the plurality of sight pins.
In accordance with yet a further aspect of the invention, a method of tuning an archery bow sight for a plurality of bows with different draw weights and target distances, includes providing an adjustment member with a plurality of travel pathways, each travel pathway being associated with a plurality of different draw weights for a particular target distance, slidably connecting a plurality sight pins to the plurality of travel pathways, and moving the adjustment member along a first direction so that the travel pathways cause each of the plurality of sight pins to simultaneously move in a second direction proportionate to its associated target distance and one of the plurality of different draw weights to thereby simultaneously tune each sight pin.

DETAILED DESCRIPTION OF THE INVENTIONReferring to the drawings, and to
The base portion 12 can include a vertically oriented dovetail-like projection 24 that projects rearwardly for use in conjunction with a complementary-shaped clamp (not shown) of a mounting bracket (not shown) so that the archery sight 10 can be mounted to an archery bow or the like and adjusted vertically in a well-known manner. A height scale 26 can be provided on the projection 24 for displaying the relative position between the archery sight 10 and the mounting bracket. Vertical adjustment of the entire archery sight 10 may be needed when initially calibrating one of the sight pins 22 of the archery sight 10 with a particular bow or other device, when changing from one arrow type to another, when shooting from different heights, such as from the ground or a tree stand, and so on.
The sight frame portion 14 preferably has an annular wall 28 that forms the sight window 20 through which the sight pin assemblies 18 and a distal target (not shown) can be viewed. Openings 30 (
The sight pin assemblies 18 are vertically oriented to demark different target distances. For example, the top sight pin 22A can be used to demark a target at 20 yards, the next sight pin 22B can be used to demark a target at 30 yards, and so on. Although five separate sight pins 22A-22E are shown, it will be understood that more or less sight pins and their respective sight pin assemblies can be provided. The sight pin assemblies 18 are almost identical in construction, with the exception of the shape of the sight pin bodies, which are configured to align vertically at the sight points, whether the sight pins are mounted in the fore or aft positions, as further described below.
