BOWSTRING-MOUNTED PEEP SIGHT The present invention relates generally to archery equipment and to devices'for improving the accuracy of such equipment in use. More particularly, the invention is directed to an improved peep sight of the type which is mounted on the bowstring of a bow.

The use of bowstring-mounted peep sights is well established in the'archery art, and many and varied types of peep sight structures have been described and employed, but none has proven completely satisfactory for its intended functions. In some instances, the mode of attachment of the peep sight to the bowstring has been inherently complex and inconvenient. In other cases the attachment has resulted in a physical imbalance in the bowstring. In still other cases the peep sight has not been securely retained and has been subject to undesirable physical shifting along the bowstring. It is to the elimination of these and other objectionable features of prior art devices that the instant invention is directed.

It is a principal object of the invention to provide an improved bowstring-mounted peep sight which is not only simple in construction, but is easily and readily attachable and adjustable, and which may be conveniently and positively secured in place at anyselectable position along the bowstring.

It is an important feature of the peep sight of the invention that it produces only a minimum of interference with the critical balance of the bowstring, and tends to preserve the dynamic symmetry of the system involved.

Other important features of the peep sight are its extremely light weight, .its low cost," and the simple manner in which it is secured on the bowstring, without tools.

A related significant feature of the invention is the ease with which the-peep sight may be removed from the bowstring, if desired.

It is a feature of a preferred embodiment of ,the peep sight of the invention that there is provided, in the region proximate the peep sight port, a surface: relief which eliminates or minimizes undesirable light reflections from the surface of the peep sight body. 2 l

Still another feature of the peep sight of the invention is that it may readily be shifted vertically along the bowstring, to any desirable position, without removal of the bowstring from the bow, and without separation of the peep sight from the bowstring.

Other objects, advantages, and features of the invention will be apparent from the following description considered in conjunction with the accompanying drawings in which:

FIG. 1 is a side elevational view of a bow with the peep sight of the invention secured in place on the FIG. 7 is an enlarged, fragmentary view of the peep sight of the invention showing details of the reflectionlimiting face of the body of the sight; and

FIG. 8 is a fragmentary cross-sectional view taken on the line 8-8 of FIG. 7 and showing the bowstring receiving channel formed in-the side of the body of the peep sight. V In effectuating and achieving the aims and purposes of the present invention, there is provided a peep sight which consists of two principal elements including a body portion and a framing member, the two components being readily assembled to provide the equivalent of a completely unitary structure.

Referring now to the drawings, and particularly to FIGS. 2-6, for the purposes of disclosure, thepeep sight 20 of the invention is shown as including a body and a frame fabricated as separate physical components, preferably of plastic composition. In the preferred embodiment of theinvention illustrated, thebody 30 of the peep sightis of a generally oval configuration, tapering to a somewhat reduced width at either end. Thebody walls 46 are formed with guide channels orgrooves 50 extending along the length of thebody 30 at opposed sides thereof. The depth of the channels50 is sufficient to permit a seating of thestrands 54 of themulti-filament bowstring 60, the strands being divided so that half the member is received in each of the opposed channels, as indicated in FIGS. 5 and 6.

Theframe 40 of thepeep sight 20 is, in the preferred embodiment illustrated, somewhat flexible and generally rectangular in form and includes opposed lateral arms orbands 64, the bands being interconnected at corresponding opposed ends through integrally formed bosses orhubs 66 having bores orpassages 70 extending axially therethrough. The diameter of the bores 70' is such as to accommodate passage of thebowstring 60 but to effect a gripping of the string frictionally.

It is believed that the mode of attachment of thepeep sight 20 to thebowstring 60 will be apparent from a consideration of the foregoing description. Thebowstring 60 is threaded through thehubs 66 of thepeep sight frame 40 and theframe 40 is slidable positioned to the desired location on thebowstring, as indicated generally in FIG. 1. That lineal segment of the bowstring lying within theframe 40 is then divided or separated into two equal bundles ofstrands 54, one of these bundles being trained and seated in each of thechannels 50 at opposite sides of thepeep sight body 30. Thepeep sight body 30 with its embracingstrands 54 is then forcibly inserted within theframe 40 so that thearms 64 of the frame overlie thestrand bundles 54 and lock the strand filaments in thechannels 5 50. Thebowstring 60 is then grasped at either end issuing from theframe 40 and pulled taut to remove any slack. The peep sight now appears as a substantially unitary assembly, the bowstring strands passing through the sight along the side walls and being completely hidden from view as depicted in FIG. 2.

While the mechanical arrangement described above is such as to maintain thepeep sight 20 frictionally secured in place on thebowstring 60, a more per- 66 and crimped in place. To remove or to shift the peep sight, it is necessary merely to detach the crimpedbands 80 from the compressible,plastic collars 66.

In the specific preferred embodiment of the peep sight illustrated, thebody 30 is formed on its principal face in the area surrounding thepeep port 90 with a light baffle contour effective to minimize objectional light reflection from that surface of the peep sight facing an archer during use of the sighting device. As shown in FIG. 2 and as evident more clearly in FIG. 7, the light baffle means comprises agrating 92 consisting of an array of alternating raised portions orribs 94 and depressed portions orgrooves 98 which serve as light defracting structures. In the specific embodiment of the invention illustrated the gratings are disposed as sectors arranged annularly about thepeep port 90, the various sectors of the array sloping inwardly toward the peep sight port to establish a generally dish-shaped recess I as seen most clearly in FIG. 6. For convenience in use, each of the opposed principal faces of the peep sight has the grating treatment.

The foregoing description and the drawings are given merely to explain and illustrate the invention and the manner in which it may beperformed, and the invention is not to be limited thereto except insofar as the appended claims are so limited since those skilled in the art who have this disclosure before them will be able to make modifications and variations therein without departing from the scope and spirit of the invention.
