Abstract
A multi-directional spreader bar assembly includes a specially formed rudder bird assembly attached to the center of a spreader bar member for trolling a plurality of lures from a fishing boat in a spread pattern. The rudder bird assembly includes a bird-like longitudinal body having an airfoil shape with fins on either side and a pair of diagonal crossing grooves centrally formed on the bottom of the body with a hole made therethrough that is off-centered from the longitudinal axis of the body and spaced apart from the crossing grooves. A rudder plate welded to a threaded stem is adapted to engage a selected one of the bottom grooves while the threaded stem extends through the off-centered hole and held in place under coaxial spring compression so that the rudder plate and stem may be released and reset into the alternate groove to switch the trolling direction of the assembly.

DETAILED DESCRIPTION OF THE INVENTION
(9) The following is a detailed description of a preferred embodiment of the present invention and the best presently contemplated mode of its production and practice. This description is further made for the purpose of illustrating the general principles of the invention but should not be taken in a limiting sense, the scope of the invention being best determined by reference to appended claims.
(10) Referring to the drawings, the following is a list of structural components of the present multi-directional spreader bar assembly, generally designated 10, and those associated structural elements shown employed in connection with the present invention: 10 multi-directional spreader bar assembly; 12 spreader bar; 14 fishing line; 16 spreader lines; 18 lures; 20 rudder bird assembly; 22 rudder bird body; 22a through hole; 22b diagonal grooves; 23 lateral fins; 24 rudder plate; 25 weld joints; 26 rudder stem; 28 compression spring; and 30 domed cap nut.
(11) Referring now to
(12) The present multi-directional spreader bar assembly 10 further comprises a specially constructed rudder bird assembly 20 adapted to engage the spreader bar 12 laterally across the span thereof and be connected thereto near the midspan of the spreader bar forward of the extended pattern of lures 18. A fishing line 14 extending from a fishing rod or outrigger pole on the fishing boat (not shown) is secured to the front of the rudder bird assembly 20 and may extend therethrough to interconnect one or more of the lures 18 in the middle of the deployed pattern.
(13) Referring now to
(14) The rudder means employed on the rudder bird assembly 20 of the present invention includes a rudder plate 24 and its associated rudder stem 26. The rudder plate 24 is a rigid rectangular member preferably made of a metallic material, such as aluminum, to provide sufficient weight, strength and durability in performance, that is further powder-coated for greater strength and protection in its marine environment. The rudder stem 26 is a threaded stud of a like metallic material similarly powder-coated that is positioned to one side of the rudder plate 24 midway along its length and attached via weld joints 25 so that the stem and the plate become an integrated member with the stem projecting from the plate and the threaded end of the stud extending from the plate in a perpendicular direction.
(15) Together as an integrated member, the rudder plate 24 with welded rudder stem 26 is adapted to fit into and engage a selected one of the crossing grooves 22b on the bottom of the bird body 22 while the threaded end of the rudder stem extends through the off-centered hole 22a to project from the top of the bird body. The fitted engagement between the rudder plate 24 and each of the crossing grooves 22b serves to resist any twisting or torquing of the plate until disengaged from the grooves. A compression spring member 28 preferably made of a stainless steel material and sized to fit axially over the threaded end of the rudder stem 26 is adapted to slide into abutting contact with the upper surface of the bird body 22 atop the hole 22a. A conventional domed cap or acorn nut 30 of a like stainless steel material is sized to fit upon and engage the threaded end of the rudder stem 26 and urge upon the outside end of the compression spring 28 through torquing to secure the position of the rudder stem in the hole 22a of the bird body 22 and hold the rudder plate 24 firmly in place in the selected crossing groove 22b. As best seen in
(16) Therefore, it is apparent that the described invention provides an improved multi-directional spreader bar assembly for trolling use in sport fishing. More particularly, the present invention provides an improved multi-directional spreader bar assembled having a specially formed rudder bird assembly that will guide and maintain the trolling pattern of the spreader bar deployment from a fishing boat in the clean water outside of the wake of the boat regardless of the speed and size of the boat. In its described construction and assembly, the present rudder bird assembly provides increased structural integrity and greater stability trolling in fishing waters than those heretofore available in the prior art. The present rudder bird assembly is rugged and durable in construction and stable in its performance despite deployment at high trolling speeds. In the preferred embodiment described above, the present multi-directional spreader bar assembly works effectively in trolling operations from fishing boats of all sizes, is relatively inexpensive to manufacture and assemble and easy to deploy.
(17) Obviously, other embodiments and modifications of the present invention will readily come to those or ordinary skill in the art having the benefit of the teachings presented in the foregoing description and drawings. Alternate embodiments of different shapes and sizes, as well as substitution of known materials or those materials that may be developed at a future time to perform the same function as the present described embodiment are therefore considered to be part of the present invention. Accordingly, it is understood that this invention is not limited to the particular embodiment described, but rather is intended to cover modifications within the spirit and scope of the present invention as expressed in the appended claims.
