Prince Assistant Examiner-Willis Little [57] ABSTRACT A peep sight is adapted for attachment to a bowstring in spaced relation above the arrow nock positioning area of the bowstring and is characterized by having a body portion which when mounted on the bowstring will align the sight opening at an angle with respect to the bowstring such that when the bowstring is drawn to its cocked position for releasing an arrow the axis of the sight opening will extend along the line of sight of the archer.
11 Claims, 5 Drawing Figures point assures precise positioning of each arrow at the same point along the bowstring so that the arrow can be consistently drawn back in the same manner each time. For example, a representative nocking point is set forth and described in United States application for patent Ser. No. 172,125, entitled BOWSTRING NOCK- ING POINT by the applicant of this invention and is characterized in particular by its ability to permit cocking or drawing of the bowstring without twisting the bowstring and misaligning the peep sight. Conventionally, the peep sight is attached to the bowstring in spaced relation above the nocking point so as to be in the line of sight of the archer and typically is affixed to the bowstring by separating the strands of the bowstring and inserting them into external grooves formed in surrounding relation to the peep sight so that the peep sight will be snugly positioned within and along the central axis of the bowstring.
A particular problem associated with peep sights presently in use is that while the nocking point may pre vent twisting or misalignment of the sight opening in a rotational direction about the axis of the bowstring, when the bowstring is drawn rearwardly, the peep sight will be tipped upwardly away from the vertical and has a tendency to become vertically misaligned with respect to the line of sight of the archenMoreover, up ward tipping of the peep sight, particularly those which are formed out of relatively flat unitary discs are often subject to undesirable reflection of light or glare making it very difficult to sight through in aligning the arrow with a target. At the same time, it is desirable to employ a peep sight which is formed out of a discshaped body of material, is extremely small, yet can be securely affixed in place in the bowstring in the manner described.
Accordingly, it is a principal object of the present invention to provide for a novel and improved peep sight which is specifically adaptable for use in an archers bowstring and which will assure accurate sighting and alignment with a target in a positive and reliable manner.
It is another object of the present invention to provide for a novel and improved archery peep sight which is compact, can be easily and rapidly installed and accurately located with respect to the nocking point on the bowstring and obviate objectionable vertical misalignment between the sight opening and the line of sight of the archer to the target.
It is a further object of the present invention to provide for a novel and improved archery peep sight which is provided with a sight opening disposed at an angle with respect to the body of the peep sight such that when the bowstring isdrawn to its cocked position the axis of the sight opening will be along the line of sight of the archer.
It is a still further object of the present invention to provide for a novel and improved archery peep sight adapted for mounting on a bowstring in predetermined spaced relation above the nocking point and which is so constructed and arranged as 'to minimize objectionable glare or reflection of light when the peep sight is tilted upwardly into the line of sight of the archer.
In accordance with the present invention, an archery peep sight has been devised which may take the form either of a generally circular or elliptical body molded or otherwise constructed out of a single piece of material to define a bowstring-receiving portion, a sight opening and a hood which forms a rearward projection of the body of the sight. In its preferred form, the peep sight takes the form of a generally circular disc having external, bowstring-receiving grooves extending along opposite sides of the disc symmetrically with respect to the center line of the bowstring and a sight opening former in a central portion of reduced thickness intermediately between the external grooves. The axis of the sight opening extends along a downward angle of inclination with respect to a center line normal to the plane of the disc and is substantially equal to the angle of displacement of the bowstring away from vertical when the bowstring is drawn rearwardly to its cocked position. In this way, the axis of the sight opening will be drawn upwardly into the line of sight of the archer when the bowstring is drawn rearwardly to the cocked position. By forming the opening on an axis disposed at a downwardly inclined angle of inclination away from a line normal to the disc, as described the effective opening size of the sight will be at its greatest when the sight is tipped upwardly into the line of sight of the archer and accordingly enables use of a smaller opening than if the opening were merely to extend on an axis normal to the plane of the disc and thus permits construction of a more compact disc. In addition, a recessed portion is formed out of the body of the disc concentrically with respect to the peripheral outline of the disc and which effectively defines a flared or divergent surface portion away from the sight opening proper both for the purpose of minimizing glare or reflection and of channeling the archers line of sight through the sight opening.
Still another feature of the present invention resides in the construction and arrangement of a hood as a rearward projection of the disc in at least partially surrounding relation to the opening as an aid to reduction of undesirable light reflection or glare.
The above and other objects, advantages and features of the present invention will become more readily appreciated and understood from a consideration of the following description of a preferred form when taken together with the accompanying drawings, in which:
FIG. 1 is a side elevational view illustrating an archery bowstring in the drawn position and alignment of the peep sight with respect to the: line of sight of the archer.
FIG. 2 is a front view in elevation of a preferred form of peep sight in accordance with the present invention.
FIG. 3 is a top plan view of the preferred form of peep sight.
FIG. 4 is a side view in elevation of the preferred form of peep sight illustrated in FIG. 1; and
FIG. 5 is a cross-sectional view taken about lines 5-5 of FIG. 2.
Referring in more detail to the drawings there is shown by way of illustrative example in FIG. 1 an ararrow A is shown in its normal position at the nocking point positioning area P, the preferred form of peep sight S is positioned in spaced relation above the nocking point positioning area so that the line of sight of the archer, as represented in dotted form at L, is through the peep sight. It can therefore be appreciated that as the bowstring is drawn rearwardly, the peep sight S is tipped upwardly with the upper section of the bowstring so that the plane of the peep sight extends at an acute angle to the vertical; otherwise, if the opening through the sight merely had its axis on a line normal to the plane of the peep sight, it should be drawn away from the horizontal so as to be at an acute angle to the line of sight of the archer.
In accordance with the present invention, the axis of the sight opening is offset from a line extending normal or perpendicular to the plane of the peep sight so that when the bowstring is drawn to its cocked position, the axis of the sight opening will extend along the line of sight of the archer as well as accomplishing other objectives as hereinafter described. In the preferred form of peep sight illustrated in FIGS. 1 .to 5, the peep sight S is broadly comprised of a unitary body provided with an outer peripheral bowstring-receiving portion 12, a centrally located sight opening 13 and a rearwardly projecting hood 14.
The body 10 preferably takes the form of a flat, generally circular disc, and the bowstring-receiving portion 12 is defined by external grooves 15 which are formed along diametrically opposite sides of the disc symmetrically with respect to a vertical center line extending along the plane of the disc. In accordance with conventional practice, the external grooves 15 permit mounting of the disc on the bowstring by separating the strands of the bowstring, inserting the disc between the strands and releasing the strands to move into snugfitting engagement against the inner surfaces 16 of the grooves. In order to assure proper vertical alignment of the peep sight with respect to the bowstring, it is therefore desirable that the inner surfaces 16 of the external grooves be formed on a radius of curvature greater than that of the disc, or be flattened somewhat, so that the strands will snugly engage the inner surfaces and prevent accidental rotation or turning of the body 10 'cher A in the process of drawing the nock N rearwardly so as to place the bowstring B in its cocked position. An
with respect to the bowstring. As best seen from FIG.
2, the inner surfaces 16 are elongated or generally elliptical and are formed symmetrically about a major axis extending along the center line of the disc and of the bowstring B.
The sight opening 13 is formed intermediately between the external grooves 15 out of a central membrane, or portion of reduced thickness, 18 which is offset with respect to the plane of the disc. Specifically, the opening is in the form of a circular bore having its main axis 19 normally extending along a downward angle of inclination designated 20 so that when the bowstring is drawn rearwardly into its cocked position and the body of the peep sight drawn upwardly as illustrated in FIG. 1, the axis 19 will be raised into the line of sight of the archer; or in other words, will be coextensive with the line of sight L.
A recessed portion 22 is formed out of the thickness of the body in surrounding relation to the sight opening and diverges or flares rearwardly from the sight opening in the direction of the archer when the peep sight is mounted on the bowstring. As best seen from FIG. 2 the recessed portion 22 is formed about a generally elliptical surface of revolution intermediately between the external grooves 15 and with the sight opening 13 located somewhat above its minor axis. As a result, the lower surface of the recessed portion beneath the sight opening is somewhat deeper and broader than the upper surface portion.
A second recessed portion 24 takes the form of a counterbore which is enlarged with respect to the sight opening 13 and extends through the thickness of the body on an axis parallel to the sight opening and on the side opposite to the first recessed portion 22.
The hood 14 projects rearwardly from the upper surface of the body 10 and in surrounding relation to the sight opening. Most desirably, the hood 14 is molded or otherwise formed integrally with the body 10 and is of generally arcuate configuration projecting rearwardly from the upper surface of the disc in a direction toward the archer and at a downward angle of inclination substantially parallel to the angle of inclination of the axis 19 of the sight opening. The hood l4 cooperates with the first recessed portion 22 to minimize light glare or reflection when the peep sight is tipped upwardly into the cocked position; and as shown preferably extends over the upper half of the disc when mounted on the bowstring.
From the foregoing, it will be appreciated that the preferred form of peep sight as described may be molded or otherwise formed so as to be of one-piece unitary construction. For example, the sight can be suitably composed of any one of the many semi-rigid or rigid plastics, rubber or rubber-like materials commercially available and can be inexpensively molded or cast in a one-step operation. By virtue of the unique construction of the sight, the sight opening being offset from the plane of the peep sight enables use of a small hole since the opening size will effectively be at its greatest when tipped upwardly into the line of sight of the archer. Forming of the sight opening in a portion of reduced thickness also affords finer or closer sighting and in cooperation with the recessed portions and hood substantially eliminates reflection of light or glare.
The specific angle of inclination of the sight opening with respect to the peep sight is averaged out, being based on the average draw length of the different length bows presently in commercial use for competition archery; and in present day bows the angle of inclination 20 of the axis 19 is on the order of 28 from the horizontal.
In use, the peep sight is positioned in predetermined spaced relation above the nock point positioning area by the archer according to his particular requirements. The sight may be readily mounted as described merely by separating the strands of the bowstring and inserting the sight between the strands so that they will snugly engage the external grooves 15. With a minimum of trial and error the archer can accurately position the peep sight so that when the bowstring is drawn to its cocked position the sight opening will be advanced into alignment with the archers line of sight.
Although a circular disc has been illustrated in the preferred form, it will be appreciated that the disc may assume other configurations, such as, elliptical; or it may be of a configuration conforming to that of the external grooves.
