Abstract

A diving fishing weight is for receiving a length of fishing line with a first end connected to a fish catching device and a second end connected to a rod and reel assembly. The fishing weight includes a dive-inducing member constructed to divethrough water, and dive-stop structure in communication with the dive-inducing member and the fishing line, and being actuable by a force exerted along the fishing line to stop the fishing weight from diving. The dive-inducing member includes body that has a front region oriented generally toward the fish catching device, a rear region oriented generally toward the rod and reel assembly, opposed sides and an upper surface. The dive-stop structure includes a passage defined by the body that extends through at least a portion of the body, with the passage having a first end proximate the front region of the body and a second end of the upper surface. The fishing weight further includes a pair of wings connected to the body and extending in generally opposed directions outwardly and upwardly from the rear portion of the body toward the front portion and the upper surface to define a wing plane. The fishing weight has a center of gravity bounded generally by the wing plane, and the center of gravity and wing plane cooperate to predispose weight to dive at a pre-determined angle. The fishing weight is also formed from a novel polymer-based composite material consisting essentially of a first volume of a curable polymeric component mixed with a second volume of iron ferrite particles, such that the unit has a specific gravity of about 7.5-8.0, with the unit including a central substantially uncured section and an outer substantially cured section.

Previousl~? ~.el.~ have used ce~ ~g f~shing weigh~ that are capable of sinl~g in heavy &ur~ent to fish in deep ri~rers~ l~kes and ~he ocea~.F5c~nti~11y, s;nlin~ fishing ~ have been used to ensure ~t ~he lure on the end of 10 the fishiI e goes down in ~e water where t~e fish are located. ~Ieavy ~urrent ~n decp watiers ~eq~es that so".~t~ more ~an a l~e be used because ~e l~e is not heavy e~ough to si~k the line to a d~s~ed depth.
Two classes of such C~~ tiOllal w~ ts include one k~wwn 9C a d~....;g~er and a second hwwn ~s a so-called floating diver. T~e do~gger inv~lves ope~g a second ~shin~g line ~at ~et~L hRbly conl-r~ to a fi~st line ttlat inr.1lld~s a l~e.
The down~iggcr ~as a lead ball ~at is effec~ve to carry the lure down in the water. A
~1icc~nn~ct m~c.1-a~ detaches ~e second lineAead ball when a ~sh pulls at the first li~e b~ taking ~he l~e. The floa~ng diver is ~onfigured to tive when pulled against a cutTent either producod na~rally or by ~olling.
Each of the abov~ two cl~sses of conYen~oItal wei~hts have drawbaclcs.
The dowmig~cr is complex and unwieldy~ ~Jthnl~ effe~ve ~s a sinlcer because of tb~
relatively extreme wei~ht of the lead b~ll which is more ~an heavy ~ough to siDk in heavy ~Te~t.

a generally arrow-shaped, dive-angle-orienting member having a wing plane, the member being predisposed to dive at a pre-determined angle when placed in the body of water; and a dive-interrupting member disposed generally along the long axis of the wing plane and extending generally forward of the wing plane, wherein the dive-interrupting member is configured selectively to prevent the fishing weight from diving when actuated by a force exerted along the long axis of the dive-interrupting member.

11. The fishing weight of claim 10, wherein the dive-angle-orienting member is predisposed to dive at an angle of approximately 70-80° relative to the water surface.

12. The fishing weight of claim 11, wherein the dive-angle-orienting member has an upper surface and a rear portion, and wherein the wing plane has a forward edge adjacent the upper surface, and a rearward edge adjacent the rear portion of thedive-interrupting member.

13. The fishing weight of claim 12, wherein the dive-interrupted member extends downwardly at an angle of approximately 15-20° relative to the upper surface of the dive-angle-inducing member.

14. The fishing weight of claim 13, wherein the dive-interrupting member is elongate and defines a passage having distal end oriented away from the wing plane

15. The fishing weight of claim 14, wherein the dive-interrupting member includes an elongate member, the elongate member being connected to and extending generally away from a front portion of the dive-angle-orienting member and having a front end distal the dive-angle-orienting member, wherein the dive-angle-orienting member and the elongate member collectively define the passage which extends from the upper surface of the dive-angle-orienting member to the front end of the elongate member at an angle in the range of approximately 15-20° relative to the long axis of the elongate member.

16. A diving fishing weight for receiving a length of fishing line with a first end connected to a lure and a second end connected to a rod and reel assembly, the fishing weight comprising:
an elongate body having a distal end, an upper surface and a proximate end, and defining a passage extending from the proximate end to a region on the upper surface beyond the midpoint between distal and the proximate ends;
a dive-inducing member that includes a pair of wings extending outwardly from opposed sites of the body to define a wing plane, the wings extending from the distal end of the body toward the upper surface of the body, and the wing plane oriented at an angle of approximately 15-20° relative to the long axis of the body.

17. The fishing weight of claim 16, wherein the body further includes an elongate tube disposed within the passage.

18. The fishing weight of claim 17, wherein the tube is substantially coextensive with the passage and at least partially extends outwardly from the second end of the passage.
