The present invention is directed to a fish hook with multiple convex facets.
Line and hook fishing is a popular and efficient means of catching fish. Typically, a fish hook is formed from round wire that has been bent into a U or hook shape, with a point at a first end, and an eye at a second end. In a typical fish hook, the point is formed into a conical or “needle point” shape. In order for a conical point to penetrate the fish's mouth, the membrane comprising the lining of the mouth must be stretched over the point before the membrane is punctured. Moreover, the point has to continue to expand the membrane to penetrate up to and beyond the barb, which can require a significant amount of energy.
In order to reduce the force required to penetrate the fish's mouth, faceted points have been developed. A faceted point provides cutting edges that allow the point to more efficiently penetrate the fish's mouth. In particular, the amount of energy required for a faceted point to penetrate a membrane can be much less than is required for a conical point of similar size to penetrate that membrane. However, faceted points typically are weak, and therefore prone to bending or breaking. This is because the faceted surfaces typically acquire a concave shape during the grinding process used to form the facets, leaving little material at or towards the apex of the point. Therefore, the strength and durability of the resulting point may be less than desired.
The present invention is directed to solving these and other problems and disadvantages of the prior art. In accordance with embodiments of the present invention, a fish hook with multiple convex facets is provided. As a result, at a selected distance from the tip of the point, the cross-section of a point as disclosed herein has more material, and therefore is stronger, than an otherwise similar point with a typical concave facet shape. Accordingly, a strong point that provides multiple cutting edges is provided.
A fish hook as disclosed herein includes a point with two or more convex facets. For example, the point of a fish hook in accordance with embodiments of the present invention can include three convex facets. In accordance with further embodiments, the point can include three or more convex facets. The facets can each have the same or different dimensions. In accordance with further embodiments, the facets can include double radius facets, where each facet follows a first radius over a first portion or distance, and a second radius over a second portion or distance.
In accordance with embodiments of the present invention, the facets have a length that is from about 2 times to about 6 times the diameter of the wire on which the multiple convex facet point is formed. In accordance with further embodiments, the curve of the convex facets follows a radius that is from about 15 times to about 150 times the diameter of the wire on which the multiple convex facets of the point are formed. In accordance with other embodiments, the ratio of the facet length to the wire diameter is about 4.5 to 1, and the ratio of the radius of curvature of the convex facets to the wire diameter is about 30 to 1, 120 to 1, 140 to 1, or 150 to 1.
Additional features and advantages of embodiments of the present invention will become more readily apparent from the following description, particularly when taken together with the accompanying drawings.
Although a barb 132 has been illustrated as part of a fish hook 104, it should be appreciated that a barb 132 is not required. Accordingly, a point with multiple convex facets 112 in accordance with embodiments of the present invention can be provided as part of a barbless fish hook 104. Alternatively, a point with multiple convex facets 112 in accordance with embodiments of the present invention can be provided with multiple barbs 132.
In various embodiments illustrated and described herein, the facets 112 are shown having equal sizes, radiuses of curvature and spacings. However, other embodiments can be provided with facets 112 of different sizes, radiuses of curvature and spacings. In accordance with embodiments of the present invention, a fish hook 104 with multiple facets is formed by grinding an end of a wire. Moreover, the wire may be of any diameter deemed suitable for a particular application of the hook 104 formed therefrom. In addition, although the body 120 has been described as comprising wire, other materials and/or forms of material can be provided with a multiple faceted point as part of a fish hook 104 in accordance with embodiments of the present invention. For example, a fish hook 104 with multiple convex facets 112 can be formed by molding a plastic or other material.
A fish hook 104 with multiple convex facets 112 in accordance with embodiments of the present invention can be defined using three parameters: wire diameter, point length L to wire diameter D ratio, and the ratio of the grind radius of the facets 112 to the wire diameter D, referred to herein as the radius of curvature of the facets 112. A fish hook 104 having multiple convex facets 112 as described herein can be formed using computer numeric control machining techniques. More particularly, by providing three axes of wire blank motion, facets 112 having a convex shape can be formed. In addition, although various radiuses of curvature have been provided as examples, embodiments of the present invention are not limited thereto. In particular, a fish hook 104 having a point portion 108 formed from multiple facets 112, where each facet is convex and therefore curves outwardly from a line drawn between the tip of the point and the starting point of the facet can be provided. Moreover, in addition to following a first radius of curvature, or following first and second radiuses of curvature, facets 112 can have three or more radiuses of curvature. In addition, the tip portion 904 can have a radius of curvature that is larger than the radius of curvature of the second portion 908 of a multiple radius faceted 112 fish hook 104.
In an exemplary configuration, a fish hook 104 featuring three convex facets 112 having a length that is 4.5 times the diameter of the body 120 and a radius of curvature that is 150 times the diameter of the body 120 is provided. For such an exemplary embodiment, at a distance of about 15 thousandths of an inch from the apex of the point, the amount of material in a cross-section at that location is about 2 times the amount of material provided in a conventional concave three facet point and as a result the strength of this exemplary embodiment is about twice that of the conventional faceted point. Other exemplary facet 112 length L to wire diameter D ratios include three to one and six to one. Other exemplary convex facet 112 curvatures include radius of curvature to wire diameter D ratios of 20 to 1, 25 to 1, 120 to 1, 140 to 1, and 160 to 1.
The foregoing discussion of the invention has been presented for purposes of illustration and description. Further, the description is not intended to limit the invention to the form disclosed herein. Consequently, variations and modifications commensurate with the above teachings, within the skill or knowledge of the relevant art, are within the scope of the present invention. The embodiments described hereinabove are further intended to explain the best mode presently known of practicing the invention and to enable others skilled in the art to utilize the invention in such or in other embodiments and with various modifications required by the particular application or use of the invention. It is intended that the appended claims be construed to include alternative embodiments to the extent permitted by the prior art.
