The present invention provides an archery sight having an elongated housing which is secured to the bow. A first opening extends through the front and rear sides of the housing while a second opening is longitudinally positioned from the first opening and is only opened to the front side of the bow. A planar mirror is secured along one side of the first opening while the housing and a parabolic mirror is contained within the housing and alinged with the second opening. The other side of the first opening is transparent so that a split image is viewed through the first opening. Both the parabolic mirror and the planar mirror are arranged so that when the halves of the split image viewed through the first opening are aligned, the bow is properly aimed. In another form of the invention, two planar mirrors are contained in the housing while a parabolic mirror is disposed across the second opening. The mirrors can also be constructed as a prism. |

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION With reference first to FIGS.
1-3, a preferred embodiment of the bow sight 10 of the present invention is thereshown and comprises a vertically elongated housing 12 having a front side 14, a rear side 16, two lateral sides 18, a top 20 and a bottom 22.
All sides 14-18 of the housing 12 are relatively thin walls so that the housing 12 defines an interior chamber 24.
As best shown in FIG.
1, the housing 12 is secured to an archery bow 26 by any conventional means, such as a bracket 28, so that the front side 14 of the housing 12 faces the direction of trojectory of an arrow 30 fired by the bow 26 while the rear side 16 faces rearwardly towards the archer using the bow 26.
In addition, the housing 12 is secured to the bow 26 so that the housing 12 extends generally vertically along the bow 26, and thus perpendicular to the direction of travel of the arrow 30.
With reference now particularly to FIGS.
2 and 3, an opening 32 is formed through the housing 12 adjacent its bottom 22 so that the opening 32 is open to both the front side 14 and rear side 16 of the housing 12 as well as the housing chamber 24.
Similarly, a second opening 34 (FIG.
3) is formed in the housing 12 adjacent its top 20 and this opening 34 is also open to the housing chamber 24.
Unlike the lower opening 32, however, the opening 34 is open only to the front side 14 of the housing 12.
With reference now to FIGS.
2-4, a planar mirror 36 is attached to the housing 12 so that it extends diagonally (see FIG.
4) across the lower opening 32.
This planar mirror 36, however, extends across only the right hand side, as viewed in FIG.
2, of the lower opening 32.
The left side 38 of the opening 32 (as viewed in FIG.
2) is transparent thus allowing unobstructed vision between the archer and the target.
Consequently, a split image of the target is viewed by the archer through the opening 32.
Referring now particularly to FIGS.
3 and 4, a second mirror 40 is secured to the housing 12 so that the mirror 40 extends generally diagonally with respect to the axis of the housing 12 and is aligned with the second housing opening 34
