A TTORNE) ARCHERY now SIGHT BACKGROUND OF THE INVENTION This invention concerns an archery bow sight. More particularly, it concerns an archery bow sight which combines a mirror in which an arrow is reflected with a sighting means.
DESCRIPTION OF THE PRIOR ART In sighting a arrow in archery, an archer can sight along the tip of the arrow to the target. However, the archer must compensate for distance and for drift or windage. For this reason, it has been desirable to provide a sight which is adjustable for distance and is simple to use. A sight of simple design is described in U. S. Pat. No. 2,378,391. A strip of felt and a strip of Celluloid superposed one upon the other and attached to an archery bow has a thrust pin thrust transversely into the felt strip, to compensate for distance and windage.
In the present state of the art, the arrow is directed by establishing two points to determine the line of flight. One point is established by a sight attached to the bow of the type described in the above U. S. Patent. The second point is formed by interacting tactile sensations between the archers arrow hand and his facial parts. The area of the face thus contacted, is referred to as the anchor point. Clearly, the sights must accommodate the physical characteristics of the archer. Therefore, because the physical dimensions vary between different archers, and various bow strengths, conventional archery sights having a fixed setting between the sighting apertures are ineffective. Accordingly, a second requirement for an archery sight is that it be free from dependence upon the physical characteristics of the archer.
SUMMARY OF THE INVENTION The preferred embodiment of the present invention which will be subsequently described in greater detail, is employed with a bow useful for target practice or for hunting.
A mounting means such as a bracket is attached to the bow to hold the bow sight in an appropriate position. On the mounting means is attached a mirror whose horizontal axis is substantially perpendicular to that vertical plane containing the centerline of the arrow. The mirror may be tilted or rotated about its horizontal axis. An adjustable sighting means is also attached to the same mounting means.
In a preferred embodiment, the sighting means comprises a vertical filament which may be a cross-hair or wire which lies against the mirror face and also lies in that vertical plane which contains the arrow centerline. The vertical filament runs straight up into the target picture. When the image of the arrow is centered in the mirror, on the vertical cross-hair, the flight will lie in the vertical plane which contains the arrow centerline and vertical cross-hair. The horizontal member of the sighting means comprises a blade shaped member which is movable and extends from the vertical filament. The movable blade can be attached to a pivotable shaft whose axis is parallel to the horizontal and can be connected to an indicating means such as a pointer which can read on an calibrated means such as a scale or dial.
The calibrated means can carry indices and set marks which are fixed on the mountingmeans or attached thereto. The calibrated means can be a range scale to determine the pointer position and thin blade 5 angle.
The method of using the bow sight of the invention involves inserting the nock of the arrow in the bow string with the arrow pointing in the direction of the target, with the arrow reflected in the mirror. Visually, the archer sights the target along the blade member with the target lined up with the vertical filament. The blade member is set at a predetermined angle tocompensate for the distance of the target from the archer.
One object of the invention is to provide a bow sight for use in archery which is mounted on a bow which eliminates tactile and muscular sensations as principal factors of the aiming process.
Another object is to provide a bow sight comprising a mirror reflecting means to direct the arrow in a predetermined direction in combination with a sighting means.
A still further object of the present invention is to provide a sighting means comprising a vertical filament and a horizontal blade shaped member which are used as a sighting plane and cross-hair sight to provide for compensating for a predetermined distance or trajecto- Still further objects and advantages of the present invention will readily occur to one skilled in the art to which the invention pertains upon reference to the following detailed description.
DESCRIPTION OF THE DRAWINGS in which like reference characters refer to like parts throughout the several views and in which:
FIG. 1 is a view of the preferred archery bow sight. FIG. 2 is a side view of FIG. 1;
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, FIG. 1 shows the preferred archery bow sight comprising mounting bracket 10 having attached thereto mirror 12 in which is reflected arrow 11. Also attached to the bracket 10 are a thin blade 13 attached to a pointer 14 adapted to read on range scale 15 and vertical cross-hair 16. The archer sights the arrow in the mirror and at the same time lines up the target at the point in the sight where the cross-hair and the blade meet, tipping the bow until the eye of the archer sees only the nearest edge of the blade, the pointer adjusting the angle of the blade having been set to correspond to a predetermined distance.
FIG. 2 showing a side view of the bow sight, shows the pivot 17 of the thin blade and the pointer.
It will be noted that the bracket holds the bow at an angle oflabout 15 to avoid visual interference with the bow string. However, the angle can be from about 5 to about 30, preferably from about 10 to about 20. Normally, the bracket is mounted a little above midpoint on the bow or a little above the point at which the 65 arrow crosses the bow.
The mirror is' normally made of glass, but other reflecting means can be used such as, for example, highly polished metal, stainless steel or the like, plastic The description refers to the accompanying drawings or polymeric material having a reflecting backing such as transparent cellulose ester with aluminum or silver deposited or coated thereon to provide a mirrorv The vertical cross-hair can be any suitable filament such as, for example, wire, hair, string, polymeric material, etc. If desired, it can be blade shaped.
The blade, as used herein, is intended to include other sighting means which would function to line up the line of sight along a plane in the same manner and could be adapted to be adjusted to correspond with a predetermined angle or distance. For example, an adjustable unidirectional sighting plane comprising a sighting tube or two or more sighting rings on a pivoting shaft to provide a unidirectional adjustable visual sighting means could be substituted for the blade, or substituted for the combination of blade and vertical cross-hair.
Normally any bow or arrow can be used. Also the material from which the bow sight, bow or arrow is constructed can vary widely. Plastic or polymeric materials can be used.
The invention has been described in detail with particular reference to preferred embodiments thereof, but it will be understood that variations and modifications can be affected within the spirit and scope of the invention.
