FISHING LURE AND METHOD OF SETTING A TRAVEL DEPTH OF THE FISHING LURE

Abstract

A fishing lure has a lure body with first and second openings. A wing system is disposed within the first opening and is movable within the first opening. A fastener is moveable within the second opening and secures the wing system to the lure body. Because the wing system is movable in the first opening, the angle of attack of the wing is adjustable and the lure can be set for various depth levels without using additional equipment such as lead weights and or planners.

DETAILED DESCRIPTION OF THE INVENTION

[0047] Referring now to the figures of the drawings in detail and first, particularly to FIG. 1 thereof, there is shown an exploded view of a fishing lure 1 formed of a lure body 2 having an opening 3 for receiving a pitch or angle adjustable wing system 4. Within the lure body 2 is a threaded aperture 5 (see also FIG. 3) for receiving or threading a fastener 6 such as a screw set for securing the wing system 4 in place in the lure body 2. The lure body 2 further has a recessed area 9 formed on a top portion of the lure body 2. An attachment ring or bridging ring 7 with an eyelet 17 for attaching a fishing line extends across the recessed area 9. The lure body 2 further has a hook ring 8 for attaching a fishing hook 60. We note that multiple attachment rings for hooks along the lure body 2 are possible and the hook ring 8 and its positioning are merely illustrative. The lure body 2 is shown to be generally bulleted shaped and is made of a buoyant hard body such as metal, plastic, a composite material or any other buoyant material suitable for prolonged water use.

[0048] FIGS. 2 and 3 show views of the completely assembled fishing lure 1 with the pitch or angle adjustable wing system 4 installed within the lure body 2.

[0049] FIG. 4 is a sectional view showing the fastener 6 engaging into and holding the wing system 4 in place. We note that the fastener 6 is threaded in the threaded aperture 5 by a screwdriver, Allen wrench or similar tool and physically presses into the wing system 4 for holding it in place.

[0050] As best shown in FIGS. 6-11, the wing system 4 has a left-wing part 10 and a right-wing part 11 which both end in winglets 12. The wing parts 10, 11 are held in place and supported by a middle portion 18 formed of two cylindrical supports 13, 14. The two cylindrical supports 13, 14 define a recess 15 therebetween in which the fastener 6 engages the wing system 4. The cylinder supports 13, 14 are dimensioned to tightly fit within the circular opening 3 of the lure body 2. Ideally, there is a bit of a friction fit between the cylindrical supports 13, 14 and the circular opening 3 such that the cylindrical supports 13, 14 can be rotated within the circular opening 3 but requiring some force to perform the rotational movement of the cylindrical supports 13, 14.

[0051] As is best shown in FIGS. 3, 5, 7 and 9, one of the cylindrical supports 13, 14 has a visual aid 16 for assisting in determining the angle set on the wing system 4.

[0052] In operation, the user of the fishing lure 1, releases or loosens the fastener 6 from the wing system 4. The wing system 4 is then rotated to the desired angled position with the help of the visual aid 16. Then the fastener 6 is once again rotated to a tightened position via the use of a screwdriver or similar tool. Additionally, the attachment point 7, 17 of where the lead wire for the fishing line is placed and aligned with the trailing edge of the system wing 4 helps to control and maintain lure depth.

[0053] Thus, the fishing lure 1 is capability of traveling at different depths below a surface of a body of water in dependence on the angle selected for the wing system 4. A typical lure body 2 has a set buoyancy dependent on its shape, size and material selection, lure line length, trolling speed and of course on the type and number of fishhooks 60 attached to the lure body 2. The wing parts 10, 11 function as an airfoil and must overcome the buoyancy of the lure body 2 in order for the fishing lure to 1 dive under the water. In operation, as the fishing lure 1 is being pulled through the water, water impinges upon the wing parts 10, 11 thereby creating a pressure gradient with the greatest pressure being observed at the portion of the wing parts 10, 11 being directly impacted by the water. As the speed of the pull increases, a point is reached in which the water pressure acting on the wing parts 10, 11 overcomes the buoyant force of the lure body 2 and the fishing lure 1 is forced under the water's surface. As is well known by those skilled in the fluid dynamic arts, one factor which affects the depth at which the fishing lure 1 will dive beneath the water's surface is the magnitude of the force of the water impinging upon the wing parts 10, 11. The magnitude of this water pressure or force, in turn, is also dependent on a number of variables which, to name a few, include the speed in which the fishing lure 1 is moved through the water, surface area of the wing parts 10, 11, the angulation of the winglets 12, and the angle of attack of the wing parts 10, 11 (e.g., the degree of downward pitch of the wing parts 10, 11 from horizontal). It follows that by providing the fishing lure 1 with adjustable wing parts 10, 11, multiple angles of attack are possible, thus the fishing lure 1 is capable of traveling at different depths below the water's surface. Ideally, the length L of the wing system 4 is between 2-8 inches depending on the need to overcome the buoyancy the fishing lure. More particularly the wing has a length of 3-5 inches, and ideally 4 inches+/−0.1 inches. However, it is noted that wing systems larger than 8 inches are possible.

[0054] In addition, to the wing system 4, the placement and location of the attachment ring 7, 17 for attaching the fishing line also plays a role in the dynamic forces acting on the wing parts 10, 11.

[0055] FIGS. 12-16 show a second embodiment of a second pitch or angle adjustable wing system 30. The second wing system 30 has a left-wing part 31 and a right-wing part 32 which are each formed of a curved wing portion or edge 37 and a straight wing portion or edge 38. The curved wing portion 37 and the straight wing portion 38 meet at an end and define a wing tip 33 rather than the winglets 12 shown in the first embodiment. The wing tips 33, as shown best in FIG. 16, are partially rounded at their ends. The wing parts 31, 32 are held in place and supported by a middle portion 39 formed from two cylindrical supports 34, 35. The two cylindrical supports 34, 35 define a recess 36 therebetween in which the fastener 6 engages the wing system 30. The cylinder supports 34, 35 are dimensioned to tightly fit within the circular opening 3 of the lure body 2. Ideally, there is a bit of a friction fit between the cylindrical supports 34, 35 and the circular opening 3 such that the cylindrical supports 34, 35 can be rotated within the circular opening 3 but requiring some force to perform the rotational movement of the cylindrical supports 34, 35.

[0056] The main difference between the two wing systems 4, 30 is that the first wing system 4 ends in winglets 12 while the second wing system 30 ends with rounded wing end tips 33. FIG. 16 shows an enlarged view of the wing end tip 33 showing a more precise partially rounded contour. Although there are minor performance differences between the winglet 12 and wing tip 33 designs, the partially rounded end tip 33 is easier to manufacture.

[0057] As with the first wing system 4, the second wing system 30 may also contain the visual aid 16 on one of the cylindrical supports 34, 35 for assisting in determining the angle set on the second wing system 30 (see FIGS. 3, 5, 7 and 9 for the visual aid 16). Ideally, the first and second wing systems 4, 30 are made as unitary or one-piece parts. For example, the wing systems 4, 30 are injected molded parts but can made from other materials such as metal, composites or wood.

[0058] FIGS. 17-25 show a second embodiment of a second fishing lure 40 having a second lure body 41 with an opening 42 in which the second wing system 30 is held. Attached to the second lure body 41 is a skirt 43. The second lure body 41 has a recessed area 44 formed on a top portion of the second lure body 41. An attachment ring 45 with an eyelet 46 for attaching a fishing line extends across the recessed area 44. The second lure body 41 in a rear area has an internal threading 47 formed therein, see FIGS. 18 and 25.

[0059] As best shown in FIG. 19, the skirt 43 is attached to the second lure body 41 by means of a fastener (bolt) 48 and a washer 49. The bolt 48 engages the internal threading 47 of the second lure body 41. More specifically, the skirt 43 has a main skirt body 54 with a through hole 55 running through the main skirt body 54. The washer 49 sits inside the main skirt body 54 at an exit point 56 of the through hole 55 aligned with the internal threading 47. A head 57 of the bolt 48 is housed in the washer 49 and threads 58 of the bolt 48 engage the internal threading 47 of the second lure body 41.

[0060] A further fastener 50 engages into a further threaded aperture 51 of the second lure body 40 for holding the second wing system 30 in place within the second lure body 40. At this point, it should be clear that the first and second wing systems 4, 40 are interchangeable in the first and second lure bodies 2, 41.

[0061] The skirt 43 is formed from a plurality of strands 52 and hidden within the strands 52 are hooks 60. The strands 52 maybe of various colorings depending on the type of fishing lure 40 desired. Finally, the lure skirt color arrangement (e.g. black on top and purple on the bottom) will be maintained because the lure head/wing design does not allow rotation of the fishing lure about its longitudinal axis.

[0062] FIGS. 21-25 show more precise views of the second lure body 41.

[0063] Not only is the fishing lure adjustable for depths because of the unique wing system 4, 30, but the wing system 4, 30 also allows the fishing lure to be trolled at higher speeds without the need of trolling weights or planners. In other words, a fisherman can carry less equipment as the wing system also substitutes for and/or provides the function of trolling weights and/or planners.
