Description

METALLIC FISHING LINE GUIDES
FIELD OF THE INVENTION The invention relates to fishing rod line guides made with metallic ring inserts in a spring frame.
BACKGROUND OF THE TECHNOLOGY
Fishing rod line guides have taken a number of different forms over the years. Early guides were made of heavy wire bent, twisted, and soldered to form a guide ring with "feet" for securing the guide to the outer surface of the rod blank. Such guides were characterized by elaborate forming apparatus and undesired stiffening of the rod flexural action due to the effects of rigidly secured guide feet spaced along the rod length and inflexible designs. Bent wire guides would often break under the circumstances typically encountered by fishing rods. Moreover, the metal wire from which the guide was formed was prone to nicks and burrs that would damage fishing lines passing through them, often at high speeds.
A more recent type of fishing rod line guide is made with a ceramic ring inserted into spring steel retainer with one or two feet for attachment. See US
Patent Nos. 4,141,132 and 4,174,583. The ceramic ring provides a hard, low friction surface that is not readily scratched and performs well at maintaining a smooth surface. The spring steel retainer and single foot design provide some measure of durability in use while minimizing undesired stiffening effects to the flex action of the rod. Unfortunately, ceramic line guides are brittle, have no elasticity, and must be secured in the guide frame with adhesive. If struck hard enough, the guides will crack and may fall out of the frames. If they don't fall out, such cracks present knife-like edges that will rapidly damage fishing lines. Pointedly, loss of the ceramic insert in the last guide on the rod (the "tip-top") is the primary reason for returned rods to manufacturers. It would be desirable to have a line guide design that retained the advantages of a single foot or double foot design and spring steel retainer without subjecting the guide to brittle ceramic contact surfaces.
5 SUMMARY OF THE INVENTION
The invention relates to a fishing rod line guide that includes a metallic guide insert secured within a guide frame exhibiting at least foot for securing the line guide frame to a fishing rod. The guide insert is retained in the frame by either a frictional fit or by mechanical engagement, preferably such as l o projections from the frame into a groove within the guide insert or by forming an expanded lip on the inserted edge of the guide insert to lock the insert within the guide frame. Friction reducing surface treatments or coatings can be applied to the guide insert to reduce friction with fishing line passing therethrough.
15 Line guides according to the invention can be manufactured inexpensively with performance and wear characteristics similar to conventional ceramic guides with higher durability.

DETAILED DESCRIPTION
5 Fishing rod guide rings according to the invention are made with a guide frame and a metallic guide insert secured within an opening in said guide frame. Preferably, the guide frame is directly engaged with the guide insert by frictional or mechanical engagement without use of an intermediate washer, shock ring, or other device. A preferred technique for securing the l o metallic guide insert within the guide frame opening employs a plurality of projections from the guide frame into the guide frame opening that will engage a groove cut into the outer periphery of the guide insert.
Outer surfaces of the guide frame that might contact a fishing guided therethrough should be smooth and curved to minimize friction on the line or
15 sharp surfaces that could cut into the guided fishing line. Exemplary surfaces include a flared horn rim on one side (figs. 2, 3, 4b, 6), flared horn rims on both sides (fig. 5), or rounded off rims on both sides (figs. 1, 4a, 7).
The guide frame can be made with a variety of materials and a variety of configurations. Preferably, the guide frame is made of a material that will 0 allow the frame to be stamped or cut from sheet stock, bent and shaped without significant fatigue or failure from the shaping operation, resist corrosion, and provide a measure of deflection or flexure adequate to survive the range of handling conditions seen by anglers over a broad cross section of lifestyles. The preferred guide frame materials include metals (e.g., spring 5 steel, stainless steel, titanium, and aluminum alloys), polymers and polymeric composites that may or may not be reinforced with fibrous or particulate additives.
The guide frame is conveniently described with reference to the figures. Guide frame has two ends and is made with a "foot" section 80 that will be 0 used to secure the guide to the fishing rod and an opening 81 opposite foot section 80. As shown, opening 81 is circular and will ultimately secure a circular or ring-shaped guide insert 1 therein. A plurality of projections 12 can be formed into the perimeter of opening 81 if guide insert 1 exhibits a surface groove 3, channel 40, or a plurality of indentations spaced to mate with projections 12. For assembly, guide insert 1 would be forced into opening 81 5 until projections 12 engaged the outside perimeter of guide insert 12.
Either before or after the guide insert is installed in guide frame 5, the guide frame is bent to provide an angle, (fig. 6), between the plane of foot section 80 and the plane of the guide insert. One or more bends can be used. Figure 6 shows the use of two bends. The preferred embodiment employs one l o bend at a location of frame 5 just above foot section 80.
In general, guide insert 1 should be standing above the upper surface of the fishing rod 8 at an angle within the range from about 90° -160° relative to the plane of foot section 80 when, as shown, the foot section is secured in the conventional manner on the handle side of the guide insert. This allows
15 guide frame 5 to bend toward the tip end of the rod in response to line tension or handling. It is possible, however, that foot section 80 could be secured in the opposite configuration in which foot section 80 points toward the tip end of rod 8.
The guide insert is preferably made of a low friction material or is 0 provided with a friction reducing coating or surface treatment that reduces drag on the fishing line as it passes through the line guide inserts during a cast or retrieve. Suitable surface treatments include bead blasting, chemical etching, or other treatments that alter the surface of the line guide material in such a manner that results in a surface texture of reduced friction with a 5 fishing line passing through the guide. In an embodiment where additional forming of the insert is not required, desired (see figs 2-4a,b), or is applied to the guide structure after formation, such a coating can be a hard, brittle coating such as chromium, or other metal or powdered metal coating with low friction, abrasion resistant character. 0 Where additional forming of the guide insert is desired, the insert coating should be sufficiently pliable and durable to be formed with the underlying metal of the insert and without cracking, flaking, or degradation of an otherwise smooth exterior surface presented to fishing line passing therethrough. Suitable insert coatings that provide additional forming operations of the metallic insert include fluorocarbon coatings (e.g., polytetrafluoroethylene), metal carbides, metal borides, metal nitrides, metal suicides, and combinations thereof.
The method for applying a coating to the guide insert will depend on the nature of the applied material, as one in this art will appreciate. The coating can be applied by spraying, dipping, painting, electroplating, plasma deposition, arc deposition, or other conventional application method.
A particularly preferred coating includes a nickel/flurorocarbon polymer coating. One embodiment contemplates the use of a mixture of nickel-coated phosphorous particles applied and sintered into the roughened outer surface of a metallic guide insert. See, US Patent No. 3,421,972 whose disclosure is herein incorporated by reference. Another nickel/fluoropolymer coating is made by a process that includes a preliminary coating of nickel applied by electroless plating with the fluorocarbon polymer infused into pores in the plating. The coating is then heat treated to create a smooth outer surface. Coating thicknesses are generally within the range of about 0.025-0.41 mm. See US Patent No. 5,660,482 which is herein incorporated by reference.
The metallic guide insert 1 generally starts as a short cylinder or tube (note figs. 1-5 and 7) that is inserted into opening 81 in guide frame blank 2 (fig. 8) until secured therein by friction or mechanical engagement with a load bearing surface formed into or from the material of guide insert 1. Guide frame blank 2 begins as a flat part that has been stamped or cut from a stock material, usually in the form of a flat or roll of material. The flat guide frame blank 2 is then bent to form vertically standing line guide frame 5. The bending locations and angles are generally selected to minimize metal fatigue while retaining adequate flexural characteristics to add durability. Frame 5 is then secured in conventional manner with a decorative thread 6 to the outer surface 7 of fishing rod 8. Preferably, guide insert 1 is inserted into opening 81 before any bending operations.
As shown in figure 2, one embodiment of the invention contemplates a frictional fit between opening 81 and insert 1. Slight expansion of opening 81 and compression of guide insert 1 provide sufficient force to hold guide insert
1 in opening 81.
If desired, a plurality of projections 12 as shown in Figs. 4(a, b) and 8 can be formed into the inside of opening 81 in frame blank 2. Projections 12 will flex relatively more than opening 81 and form a one way means to allow installation of the guide insert with flexure of projections 12 yet hold the insert in place by snapping into channel 40.
Figure 3 illustrates another embodiment where insert 1 is provided with one or more surface features, such as groove 3, that will engage retaining lip projection 4 that has been formed into frame blank 2. Groove 3 is an embodiment of only one of many possible surface features on the outside diameter surface of insert 1 and can exhibit any number of profile shapes: an angled groove is illustrated in figure 3. Groove 3 can also be in a number of surface features that are not illustrated: a plurality of indentations, a square cut channel, a "V" channel, a concave profile, or virtually any other shape that can be formed or machined into the outside exterior surface of guide insert 1 that can engage with the inside surface of opening 81 in frame blank 2 or projections 12 therefrom.
Another or further embodiment for securing guide insert 1 in opening
81 is shown in figures 1, 4, and 7. Like Figure 2, guide insert 1 starts as a short tube with original lip 14 that is inserted into opening 81 with a snug fit to retain the insert in position as die punch 9 with profiled perimeter 10.
Perimeter 10 urges guide insert 1 outwardly against the inside edge of opening
81 and forms new lip 13 against the opposite side of frame blank 2.
Preferably, new lip 13 is formed on the tip end side of frame blank 2 from the orientation that foot section 80 would be mounted on fishing rod 8 pointed toward the rod's handle end. Perimeter 10 of punch 9 can take any number of possible shapes although preferred profiles are those of smoothly curving profiles that guide a relatively soft polymeric line with a minimum of friction. Figure 1 shows profile 10 with a 45° chamfer. Figure 4 shows guide 1 with a "trumpet horn"
5 profile on lip 13.
A preferred embodiment of guide insert 1 is shown in figure 7. Notably, guide insert 1 exhibits a lipless, leading edge 70 of a first diameter (dl) and a lipped trailing edge 71 of a second diameter (d2). Each diameter of guide insert 1 is an outside diameter. Frame opening 2 has an inside surface 72 of l o third diameter (d3) that is larger than the outside diameter of leading edge 70 but smaller than the outside diameter of trailing edge 71.
Guide insert 1 is mechanically secured in frame blank 2 by forming a forward edge lip 73 on guide insert 1 where the outside diameter of lip 73 is greater than the inside diameter of inside surface 72 in frame blank 2. Most
15 conveniently, lip 73 is formed by expanding the diameter of leading edge 70 with a punch or other pressing tool (as shown in fig. 1) that will leave a smooth contact surface along the inside surfaces of insert 1.
