DETAILED DESCRIPTION OF THE INVENTION

Looking at FIGS. 1-4, a fishing lure 10 is illustrated that generates a desired sound for attracting fish using a single composite weight 14. The fishing lure 10 has a partially hollow body or shell 12 that surrounds the composite weight 14. In particular, the body 12 has a forward end 16 and a rearward end 18, with two side walls 20, 22 positioned between the forward end 16 and the rearward end 18. The outer surfaces of the side walls 20, 22 are substantially mirror images of each other to provide a uniform outer body 12, with the interior portions of the side walls 20, 22 being designed to fittingly engage each other. That is, one side wall 20 has male connectors and the other side wall has female connectors to unite the two side walls 20, 22 in a single body 12. Each side wall 20, 22 additionally has an interior surface 24 that surrounds the composite weight 14. More specifically, a series of interior partitions or dividing walls 26 are connected to at least one of the side walls 20, 22 to define a series of chambers in the body 12 of the fishing lure 10. In the embodiment illustrated in FIGS. 2a and 2b, the body 12 has three interior partitions 26 that define four chambers: a first chamber 28 proximate said forward end 16, a second chamber 30 proximate said rearward end 18, a middle chamber 32 between the first and second chambers 28, 30, and an upper chamber 34 abutting the first chamber 28.

As illustrated in FIG. 2a, the composite weight 14 is positioned in the first chamber 28 at the forward end 16 of the fishing lure 10. The first chamber 28 has a shape commensurate with the shape of the composite weight 14, with the dimensions of the first chamber 28 being greater than those of the composite weight 14. The composite weight 14 is substantially triangularly-shaped (see FIG. 5), and includes a base member 36 and a tungsten knocking member 38 (see FIG. 7). The base member 36 in the embodiment described herein is made of lead, although other materials may be incorporated to adjust the sound of the lure 10. The base member 36 in the embodiment illustrated in FIGS. 5-8 includes two planar surfaces 39a, 39b that are separated by a base rocking surface 40a and side walls or edges 40b, 40c. The tungsten knocking member 38 is positioned at the uppermost edge of the base member 36 opposite said base rocking surface 40a, namely, at the junction of the side walls 40b, 40c of the base member 36. The composite weight 14 is positioned in the first chamber 28 of the body 12 with the base rocking surface 40a resting on the interior surface 24 of the body 12 to pivot in direction A (see FIG. 4). In the embodiment illustrated in FIG. 8, the base rocking surface 40a has substantially arcuate edges extending along the length of said base rocking surface 40a. As a result, with the tungsten knocking member 38 being at the top of the composite weight 14, the tungsten knocking member 38 will swing or pivot from side to side inside the lure body 12 in direction A as the fishing lure 10 is drawn through water. The pivoting action will cause the tungsten knocking member 38 to periodically engage the interior surfaces 24 of the side walls 20, 22, thereby generating the desired sound for attracting fish. Since the tungsten knocking member 38 is proportionally heavier than the base member 36, the swinging motion will occur at various retrieval speeds (including relatively slower speeds) while continuing to emit a sound when other similarly shaped lures will not make any sound for attracting fish.

Continuing to refer to FIGS. 5-8, the composite weight 14 is illustrated in greater detail. In the embodiment illustrated in FIG. 7, the tungsten knocking member 38 of the composite weight 14 is shown having a substantially cylindrical or barrel-shaped head portion 42 connected to a substantially quadrangular foot 44. Looking to FIGS. 6 and 8, the length L1 of the cylindrical head portion 42 is substantially perpendicular to the length L2 of the base rocking surface 40a. As a result, the cylindrical head portion 42 is shaped to engage the side walls 20, 22 as the composite weight 14 pivots on the base rocking surface 40a of the base member 36 (see FIG. 4).

Furthermore, the base member 36 substantially surrounds the foot 44 of the tungsten knocking member 38 to securely maintain the connection between the base member 36 and the tungsten knocking member 38. That is, in producing the composite weight 14, the tungsten knocking member 38 is cast first. The base member 36 may will then be molded over the foot 44 of the tungsten knocking member 38 to secure the connection between the members 36, 38, although other means for positioning the base member 36 around the tungsten knocking member 38 may be employed. While the foot 44 may take on shapes other than the substantially quadrangular shape shown in FIG. 7, the shape of the foot 44 should be such that the foot 44, once secured to said base member 36, will not be able to disengage or disconnect from the base member 36. In addition, although the base member 36 is described as being made of lead, it is noted that other materials lighter than tungsten may be used in conjunction with the tungsten knocking member 38 to produce the desired sound. That is, the base member 36 may be made of another metal or even have a plastic body to change the center of gravity of the composite weight 14 and transfer more impact from the tungsten knocking member 38 into the side walls 20, 22 of the fishing lure 10. Thus, using a tungsten knocking member 38 and casting or positioning another material around it will achieve a different tone.

In the embodiment shown in FIG. 7, the size or volume of the base member 36 is at least triple the volume of said tungsten knocking member 38. Since tungsten is heavier than lead, the weight and position of the tungsten knocking member 38 will direct the pivoting movement of the composite weight 14 when the fishing lure 10 is suspended in water. Furthermore, the shape of the composite weight 14, with the tungsten knocking member 38 positioned above the base member 36, allows that only a particular part of the tungsten knocking member 38 is exposed to obtain a certain sound emitted from a fishing lure 10. Although the composite weight 14 is illustrated in a generally triangular shape, it is noted that additional shapes for the composite weight 14, such as a quadrangle, circle, or oval, may be used to generate a similar sound for attracting fish. With such modifications, the first chamber 28 may be adjust similarly to direct the pivoting movement of the composite weight 14 in the lure body 12.

Furthermore, it is noted that tungsten is much harder and heavier than lead or steel. As a result, tungsten creates twice the sound of other weights (such as lead), and provides more vibration to help induce reaction strikes by fish. Furthermore, tungsten is more durable than other metals. For example, tungsten is two to three times more rigid than copper or steel. As a result, the tungsten knocking member 38 will not deform or flatten like a lead weight after repeated engagement with the side walls 20, 22, and tungsten knocking member 38 will retain its sound properties over time.

It is to be noted that another supplemental weight 33 may be included in the body 12 to balance of the fishing lure 10 with the composite weight 14 so that the fishing lure 10 will be retrieved in water in a substantially natural appearing fashion, as shown in FIG. 2a. The supplemental weight 33 in the embodiment illustrated is positioned in the middle chamber 32. The supplemental weight 33 is not used to create additional noise in the lure body 12; rather, it is used to stabilize the distribution of weight in the fishing lure 10.

Through testing the design described above, the tungsten knocking member 38 wrapped with the base member 36 emits a higher pitch tone that is not found by using other materials in fishing lures. The sound produced by this combination was found to produce fish strikes when other similarly-shaped fishing lures did not.

Having thus described exemplary embodiments of the present invention, it should be noted by those skilled in the art that the within disclosures are exemplary only and that various other alternatives, adaptations, and modifications may be made within the scope of the present invention. Accordingly, the present invention is not limited to the specific embodiments as illustrated herein, but is only limited by the following claims.
