Adjustable type arrow rest for a bow

Abstract

An arrow rest is attached to a plate that has an arrow pressure point contact area which engages the side of an arrow shaft as it lies on the rest. The plate does not attach directly to the bow handle but is attached to a spring-biased plunger which is movable toward the bow as the arrow passes. The arrow rest and arrow pressure point contact area move in and out with the spring-biased plunger. The plate is adjustably movable toward and away from the bow on which it is mounted.

Description

The present invention relates to archery bows and, more particularly, to an attachment for an archery bow which is designed to engage both the bottom and one side of the arrow, and which attachment may be easily retracted toward the bow by the arrow's action as it passes over the bow.

It is known in the art that as an arrow is released by an archer the arrow shaft normally deflects around the bow window. An improper shot could cause the arrow to strike the bow or an arrow rest attached solidly to the bow, producing an erratic flight.

Various devices have been utilized heretofore in an effort to avoid irregularities in arrow release and to increase accuracy. For example, various forms of arrow supports on which the arrows rest have been utilized. It is also known to utilize such devices as the spring-biased plunger disclosed in U.S. Pat. No. 3,232,286 to Gyton and No. 3,482,563 to Pint which engages the side of an arrow while on an arror rest, and which plunger retracts as the arrow passes over the bow. In the structure of the Gyton and Pint patents, the arrow rest is attached to the bow and is stationary and is not connected to the spring-biased and movable plunger member which engages the side of the arrow.

Some devices have met with varying degrees of success to overcome the problems of irregularities in arrow release and increased accuracy.

A principal novel aspect of the present invention relates to an improved apparatus for supporting and aligning an arrow as it is shot from the bow. In the present invention, the arrow rest is integrally connected to an arrow pressure point contact area which is in contact with the side of the arrow. This area is attached to a spring-biased plunger and is retractable toward the bow as the arrow moves past. In this fashion, the arrow rest moves in conjunction with the arrow pressure point contact area at all times to simplify obtaining good arrow flight characteristics.

Among the several objects of the invention may be noted in particular the provision of a combined arrow rest and arrow presssure point contact area; the provision of bias means whereby the arrow rest and arrow pressures point contact area move in unison both when the system is being adjusted and when it is in actual use; and the provision of an arrow rest which is positioned to maintain an arrow supported thereon in contact with the pressure point contact area. Other objects and features will be in part apparent and in part pointed out hereinafter.

The invention accordingly comprises the constructions hereinafter described, the scope of the invention being indicated in the following claims.

In the accompanying drawings, in which one of various possible embodiments of the invention is illustrated,

FIG. 1 is a partial perspective view of the combined arrow rest and arrow pressure point contact area of the invention mounted on a bow;

FIG. 2 is a view taken primarily in horizontal section along line 2--2 of FIG. 1, with spacing from the bow exaggerated and with the position of the arrow being shown in dash lines; and

FIG. 3 is a perspective view of the combined arrow rest and arrow pressure point contact area.

Corresponding reference characters indicate corresponding parts throughout the several views of the drawings.

Referring now to the drawings, and more particularly to FIG. 1, reference numeral 10 generally designates a bow which has a conventional grip and a sight window formed with a shoulder 12. The face 20 of the bow faces the archer when in use.

A combined arrow rest and arrow pressure point contact area generally designated by reference number 22 is attached to a spring-biased plunger, rod or stem above shoulder 12.

Referring to FIGS. 2 and 3, this combined device comprises a generally vertically disposed plate member 24. An arrow rest 26 is attached to plate member 24 by having its lower end 28 secured in a slot formed by securing members 30, 32 adjacent the bottom of plate member 24. In the illustrated embodiment the arrow rest is in the form of a thin vane or strip of nylon or similar material. The arrow rest is inclined upwardly at a small angle in the order of 4.degree.-6.degree. and outwardly at an angle of 15.degree.-30.degree. so that an arrow 34 (shown in dash lines) may be supported thereon and held in contact against the region 36 adjacent the rear upper end of plate member 24. Region 36 constitutes the arrow pressure point contact area in contact with the arrow. On the other side of plate member 24 from arrow rest 26 there is a tubular extension 38 which has internal threads in threaded engagement with the end of a rod 40. As seen in FIG. 2, rod 40 passes through an opening in the bow handle from an internal cavity 42 in the bow. A collar 44 on rod 40 limits its outward movement. A spring 46 acting upon collar 44 tends to bias rod 40 to its outermost position to hold the arrow rest and arrow pressure point contact area 22 spaced outwardly from bow 10. There may be provision to adjust the tension on spring 46 via a set screw 47 and an adjustment knob 49 (FIG. 1) such as in the aforementioned Pint U.S. Pat. No. 3,482,563.

At the other end of plate member 24 there is a transverse rod 48 which telescopes within a tubular member 50 fixed to bow 10. The reception of rod 48 within tubular member 50 serves to maintain plate member 24 and the associated structure in the desired horizontal orientation irrespective of any turning movement of threaded rod 40 or pressure of arrow on rest 26.

In operation, the archer may adjust the initial position of plate member 24 and consequently of pressure contact area 36 relative to the bow via set screws or the like. Since arrow rest 26 is attached to plate member 24, a simultaneous and corresponding change in the position of the arrow is achieved. When an arrow is released, the arrow's action acting against the arrow pressure point contact area 36 may cause the device 22 to move toward the bow against the bias of spring 46. Since arrow rest 26 moves in conjunction with the pressure point area 36 at all times, this substantially simplifies obtaining good arrow flight characteristics since there is no change relative to each other between the portion of the device supporting the bottom of the arrow and the portion of the device contacting the side of the arrow adjacent the bow.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
