IO N [4 m FIG. 2 l i 8 l6 GJ 22 W20 24 INVENTOR CHARLES PETRO SKY ATTORNEYS lltllNG-MOUNTED DEFENSIVE BLADE BACKGROUND OF THE INVENTION With the rising crime wave, it is extremely desirable that people who must be exposed in heavy crime areas have some sort of defensive weapon which is innocuous appearing, which is not extremely dangerous to either party, which cannot be used against the party carrying the weapon and will inflict damage upon an attacker so as to ward off an attack while at the same time marking the attacker for future identification for prosecution purposes. A widespread use of gas cartridges has risen to fulfill the need. However, gas cartridges are not handy to carry in an immediately ready position. An attacker may wrest a cartridge away from another person, and the contents of a gas cartridge may prove dangerous to the user. Tear gas cartridges are expensive and are good for only one appli' cation. The present invention provides repeated uses. Knives and guns are not the answer because they cannot be kept immediately available for use, and because they may be used against the bearer by the attacker.

SUMMARY OF THE INVENTION The present invention provides an attacker-repelling and marking weapon which is always ready for use, which cannot accidentally injure the bearer, and which cannot be used against the bearer. A finger ring which appears to be a plain wedding band has mounted on the inside thereof an inward and downward curved pointed and sharpened triangular blade. To insure that the ring and blade do not turn in the hand so as to accidentally injure the wearer, and to insure stability when the blade is being used against the attacker, the ring is provided with stabilizing wings which extend laterally from a bottom edge of the ring below the curved and pointed blade. The supporting wings overlie the palm of the hand in an area immediately below the knuckles, usually of the middle and little fingers. The ring is worn as is conventional preferably on the ring finger between the knuckle and the first joint. The supporting wings lie flat against the palm when the fingers are extended or when the hand is curved into a fist, and there is no discomfort or distortion of the fist from these wings. When the hand is curved into a fist, the curved blade underlies the first knuckle of the ring finger and the point is free from any contact with the skin, being disposed in a roughly square space formed interiorally by a bent finger. Besides acting in a stabilizing capacity, the wings also serve as a reminder of the wearing of the ring so that the wearer is reminded to keep the palm and internal sides of the fingers of the hand on which the ring is being worn away from the body.

Preferably, the ring is constructed of a chrome-cobalt, stainless steel, brass or gold-plated tube having an appropriate finger size inner diameter and having an axial length of approximately three times a conventional width of a ring. Two slits are made through the wall of the tube, dividing the tube into equal thirds and terminating the slits with approximately one quarter to one half the circumference of the tube remaining unslit. The lower portion of the tube is cut axially opposite the portion which remains attached to the tube, and two stabilizing wings are bent forwardly so as to be tangential with the remaining portion of the tube. The major portion of the other outer partially severed ring is removed by making slanted cuts between a point centered opposite the line of juncture between the sections to the ends of that line, thus forming a triangular point. The slanted lines are sharpened and the triangular portion is bent forwardly away from the central ring section and downwardly so that the point is directed generally downwardly and only slightly outwardly with respect to the ring. Burrs are polished, and the ring is ready for use. The ring may be constructed in other forms, but it is especially useful that the supporting wings be joined to a lower edge of the ring and that the point be curved outwardly and downwardly from an upper edge of the ring directly opposite the jointure of the supporting wings with the ring.

The broad objective of this invention is the provision of a defensive and marking weapon which is a ring with an inwardly, downwardly pointing sharpened triangular blade and stabilizing wings extending laterally from a segment of the ring on which the pointed blade is mounted. This and further objectives of the invention will be apparent from the detailed description of a preferred embodiment of the invention which is described with reference to the drawing.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view of the ring. FIG. 2 is a side view of the ring. FIG. 3 is a rear elevation view of the ring.

DETAILED DESCRIPTION OF THE DRAWING With specific reference to FIGS. ll, 2 and 3, a defensive ring generally indicated by the numeral l is preferably cast from a decorative metal. A ring body portion 2 is constructed to fit a particular finger size and is preferably worn on a ring finger of the hand with the cutting blade and antitwisting bar pointing inwardly on the palm side of the finger. Ring body 2 has an upper edge 1 and lower edge 6. A triangular blade generally indicated by the numeral 10 is integrally formed with ring body 2 with a base 12 of the blade attached to upper edge 41 of the ring body. A midportion M of blade 10 arcs upwardly, outwardly and then downwardly from base 112 to an outer pointed end 16. Side edges 18 of blade ll0 are sharpened as is point 16.

When the ring is worn, midportion M of blade 10 is positioned about half way between the knuckle and first adjacent joint of the ring finger. Thus, when the hand is bent inwardly as in making a fist and even when the hand is tightly clenched into a fist, the arc portion 114! of the blade simply underlies the flesh of the ring finger so that there is no danger of cutting the flesh and so that the ring is comfortable in its worn position. The entire arc blade 10 fits within a generally rectangular area formed between the back of the knuckle and the bent ring finger with the point located in such a manner that it is approximately halfway between the first and the second joint of the finger in a clenched position. Thus, cutting of the hand and discomfort are avoided.

To insure that the ring does not turn as it is worn, or as it is used, as in fending off an attacker or marking an attacker, a stabilizer bar 20 is provided along the base of the ring. Stabilizing bar 20 joins ring body 2 along an integrally formed junction 22 on lower edge 6 of the ring body. Wings 24 extend generally outward from the ring body so as to underlie knuckles of the middle and little fingers when the ring is worn. When the palm of the wearer is bent, wings 24 underlie the middle and ring fingers just above the knuckles In the preferred embodiment, which is shown in the drawings, two wings extend in opposite senses of direction from the ring body, and the wings extend generally tangentially from the body.

While the invention has been particularly shown and described with reference to a preferred embodiment thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
