DETAILED DESCRIPTION

(8) Referring first to FIG. 1, a spinning lure 10 is shown in exemplary form in order to teach how to make and use the claimed invention. Lure 10 comprises a plug body 20 formed with a suitable buoyancy, e.g. various plastics typically used for such lures to give them the desired buoyancy characteristics. Plug body 20 has a substantially constant diameter front portion 22 over approximately the first half of its length, and a tapered diameter rear portion 24 over approximately the second or rear half of its length.

(9) The rear tapered portion 24 of plug body 20 is provided with a circumferential array of longitudinal fins or vanes 26 integrally molded therewith, in the illustrated example straight and parallel to one another and to the longitudinal axis Y of the plug body 20. Vanes 26 have side edges 26a, and ends 26b terminating at tail 25 of the plug body and substantially perpendicular to side edges 26a. While the illustrated example shows six vanes 26, the number may vary but with a preferred minimum of three vanes.

(10) Illustrated vane side edges 26a define a substantially constant diameter around (and radially spaced from) the sidewall surface of tapered rear portion 24 of plug body 20. Vanes 26 may also be tapered rearwardly, but should be less-tapered than the side surface of rear portion 24 of the plug body to maintain the side edges' outward spacing from the outer surface of rear portion 24 of the plug body.

(11) Illustrated vane side edges 26a also define a maximum diameter less than the maximum diameter of substantially cylindrical front portion 22 of plug body 20, for example on the order of 70-90% of the diameter of front portion 22.

(12) Still referring to FIG. 1, lure 10 also includes a pair of spaced spinner wings 28 extending from opposite sides of the surface of front portion 22 of plug body 20. Wings 28 are preferably molded integrally with plug body 20 from the same material, with sufficient thickness to be substantially rigid in use, like a propeller, with minimal or no deformation while spinning through the water, and holding their shape (i.e, not deforming or flexing significantly) during typical handling and storage by a fisherman. Alternately, wings 28 may be formed from a different plastic or other suitable material and attached to plug body 20 using various known techniques including adhesive bonding, insert molding, or others. Illustrated wings 28 have outer side edges 28a that define longitudinally twisted curves extending from the front portion 22 of plug body 20 toward the rear end or tail 25 of the plug body, with radially outermost points 128a located longitudinally upstream or forward of rounded wing tips 28b. In the illustrated example, wing tips 28b are located radially inward of outermost wing tangents 128a.

(13) Referring to FIG. 3, the outer ends 28b of wings 28 extend beyond a maximum tangential width of the plug body as defined by lines X substantially parallel to the leading portions 28c of outer edges 28a when viewed from the front end of the lure. This radial extension of wings 28 imparts a preferred spinning action to the lure.

(14) Vanes 26 are shown as straight vanes, which in combination with the propeller-like twist of the wings 28 keeps the lure spinning true while being pulled through the water. Vanes 26 are also believed to create extra turbulence and scent dispersal as the lure is pulled through the water.

(15) Plug body 20 has an annular interior volume 30, shown in hidden lines in FIG. 2, with a central stem 34 defining a longitudinal center line passage 34a and separating the passage from the annular interior volume 30 around it, the annular interior volume terminating at a rear or lower end at interior end wall 32 located within the rear region of the plug body 20 within tapered portion 24. Interior end wall 32 is preferably conical and/or tapered as illustrated, to define interior annular volume 30 as a tapered cavity to smoothly slow the flow of water through the lure and build up and sustain what is believed to be a desirable back pressure that helps drive or lift the lure upwardly. Annular interior volume may also include vertical internal walls 31 connecting or extending between the central stem 34 and the outer wall of the plug body, with a height less than or equal to the height of stem 34. In the illustrated example, vertical internal walls 31 are substantially coextensive with the bases of wings 28 for strength and rigidity, and may even comprise inner portions of the wing bases inserted through corresponding apertures in the plug body wall into the annular interior volume 30 and joined to the central stem 34.

(16) Annular interior volume 30 also provides a receptacle for known fish-attracting scent materials, as well as providing a through-flow of water that when exiting the rear of the plug body 20 is believed to create turbulence and a lifting action.

(17) Central passage 34a opens at a first forward end at the front end 23 of the plug body, and exits centrally at plug body tail 25, so that fishing line and water may pass through passage 34a from the front to the rear of plug body 20 along its longitudinal axis Y.

(18) Water enters annular volume 30 through open front end 23 of the plug body, and exits the plug body through small, evenly spaced flow passages 32a formed through interior volume end wall 32 and opening at opposite points along the sidewall of the rear tapered portion 24 of the plug body. The reduced front sectional area of the flow passages 32a and passageway 34a relative to the greater front sectional area of annular volume 30 is believed to result in a turbulent flow around and behind the plug body that causes a desirable intermittent lifting and jigging action to attract fish, in addition to the spinning action caused by wings 28.

(19) Description of Operation

(20) In operation, the lure 10 is used by threading a fishing line through central passageway 34a and attaching hooks, weights, bait, supplemental lures, etc. behind the tail 25 of the plug body, and then pulling the lure 10 through the water by trolling and/or by repeatedly pulling it manually back and forth through the water or by letting it spin in a river current. A fish-attracting scent may optionally be inserted into the forward annular interior volume 30 of the plug body 20, and the flow of water through the interior of the plug body helps the scent to be dispersed in a turbulent spinning pattern behind the lure as it is trolled or pulled through the water.
