Aiming device for archery bows and other objects

DETAILED DESCRIPTION Referring to FIG.
1 the aiming device incorporating the principles of this invention is generally indicated at 10 and is shown to be detachably secured to the central portion or section 12 of a conventional archery bow 14 having the usual upper and lower flexible portions 16 and 18.
The central section 12 of the archery bow extends between and is joined to the upper and lower portions 16 and 18 as shown.
Bow section 12 is formed with a handgrip 20 below an arrow rest 22.
A bowstring 24 mounted on the bow is shown to be in engagement with the nocked end of an arrow 26 seated on the arrow rest 22.
In the illustrated embodiment the aiming device of this invention mainly comprises a flat-sided one-piece leveling plate 30 or pad, a flat-sided one-piece sight-supporting plate 32, and a front sight unit 34 adjustably mounted on the forwardly facing end of plate 32.
The subassembly of plates 30 and 32 is detachably fixed to the bow section 12 above arrow rest 22 by a pair of mounting screws 36 and 37.
Screws 36 and 37 may be of the flat-headed allen wrench type.
Plates 30 and 32 may advantageously be formed from lightweight aluminum.
As shown in FIG.
4, screw 36 extends through aligned smooth walled bores in plates 30 and 32 and is threaded into a blind tapped bore 38 which is formed in the left-hand side of the bow section 12.
Screw 37 similarly extends through aligned smooth walled bores in plates 30 and 32 and is also threaded into a blind tapped bore 39 in bow section 12.
The formation of bores 38 and 39 is the only bow modification required for detachably mounting the aiming device of this invention on the bow.
As shown, the longitudinal axes of bores 38 and 39 and hence of screws 36 and 37 lie in a common plane normally intersecting bow section 12.
The bores formed through plate 32 for receiving screws 36 and 37 are indicated at 41 and 42 in FIG.
5 and may be countersunk as shown to receive the heads of the mounting screws.
Bores 41 and 42 are formed through a generally rectangular body portion 40 of plate 32 as shown
