Abstract
Description
[0001] The rubber fishing lure usually consists of a rubber-like body.
[0002] The rubber fishing lure is designed to slow its descent after being retrieved by the reel and rod. It features a curved, concave tail plate (1) and two rearward-facing outlet channels (1a) on top. Furthermore, it has forward-sloping ribs (2). Additionally, it has forward-facing, concave, shark-like scales (3), concave forward-facing pectoral fins (4), and a drag plate (5) on the head.
[0003] The problem is that a soft plastic lure sinks relatively quickly to the bottom after the line tension is released, and there is no tail movement. Predatory fish focus up to 98% of their feeding behavior on soft plastic lures that sink with tail action.
[0004] In the development of the rubber fishing lure in question, the following features were incorporated in combination: the concave tail tip (claim 1), the forward-slanting ribs (claim 2), the shark-like shaped, forward-facing scales (claim 3), the concave, forward-facing side fins (claim 4), and the brake paddle attached to the head (claim 5), which create a braking effect during sinking.
[0005] The invention specified in claim 1, with the concave shape and the two outlet channels (1a), causes the tail tip to wobble as it descends.
[0006] The invention specified in claim 2 generates water resistance through the forward-facing, inclined ribs (2), which delays sinking.
[0007] The invention specified in claim 3 produces, by means of the concave shape of the scales (3), the delayed sinking of the bait to the bottom.
[0008] The invention specified in claim 4 produces a delayed sinking of the bait to the bottom by means of the concave, forward-facing side fins (4).
[0009] The invention specified in claim 5 produces a delayed sinking of the bait to the bottom through the selected shape of the brake vane (5).
[0010] The invention specified in claim 6 produces a delayed sinking and an increased wobble of the tail tip by means of the sickle-shaped fin located on top of the tail stem.

Claims
[1] Rubber fishing lures (delayed sinking) characterized by , The addition of a tail plate creates a wobbling action, slowing the lure's descent. The tail plate of a soft plastic lure typically serves to attract the attention of a predatory fish through its back-and-forth movement. For manufacturing reasons, the plate's surface is flat. The innovation is that the tail plate is concave on the inside, like a parachute (1). This slows down the fall of the soft plastic lure with jig head rig, leading to an increased number of bites, since approximately 99% of bites occur during the lure's fall. The curved tail plate (1) contains a volume of water that dampens the back-and-forth wobble of the plate because the enclosed water mass must also move. The innovation lies in the fact that on both sides of the tail plate, which is connected to the body of the soft plastic lure at the upper end of the caudal peduncle, there is a rearward-facing, curved outlet channel (1a) through which the water collected in the cavity of the concave tail plate can escape. These two outlet channels result in a significantly higher frequency wobble of the tail plate. The tail plate is connected to the soft plastic lure at its upper end by a short, flat, vertical caudal peduncle. This short caudal peduncle transfers the vibrational energy of the tail plate to the soft plastic lure, causing it to also wobble back and forth.Long, thin tail stalks may make the plate wobble more, but almost no kinetic energy is transferred to the fish's body. The kinetic energy remains in the tail plate. The protection applies to lure lengths between 30mm and 300mm. The length of the tail section, excluding the tail plate, can be between 5% and 25% of the lure's total length. The diameter of the tail plate can be between 5% and 20% of the lure's total length. The tail plate can be round, oval, elliptical, heart-shaped, teardrop-shaped, square, or rectangular. The angle of the tail plate to the soft plastic lure is between 70 and 120 degrees (1c). [2] Rubber fishing lures (delayed sinking) characterized byThe body of the soft plastic lure has ribs angled diagonally forward when viewed from top to bottom (2). The angle of the ribs can range from 90 to 35 degrees (2a). The ribs protrude 30-100% further on both sides of the lure than the original shape of the lure without ribs. The ribs are inclined forward. The rounded shape of the rib base (2b) creates a counter-current, similar to the thrust reverser of an aircraft turbine. This significantly slows the lure's descent. The angle of inclination (2c) can range from 85 to 35 degrees. The ribs may also have a concave curve on the forward-facing side. The soft plastic lure can have between 2 and 15 ribs. When rigged with a jig head, the soft plastic lure falls almost vertically to the bottom due to gravity. The angled ribs (2c) act like shear boards and pull the rubber lure with jig head away from the angler as it sinks.This allows the rubber lure to remain in the fishing area longer than a rubber lure without these forward-leaning, slanted and widely extending ribs, thus increasing the chances of a catch. [3] Rubber fishing lures (delayed sinking) characterized byIt is known that shark scales create low water resistance. The scales on the soft plastic lure are modeled after those of a shark. Their arrangement against the direction of water flow (3) and their concave shape create significant water resistance, considerably slowing the lure's descent to the bottom. The rounded shape of the scale base (3a) creates a counter-current, similar to the thrust reverser in an aircraft turbine. This further slows the lure's descent. The scale pattern can cover the rear 80% of the lure, or a portion thereof. The number of scales can vary from 3 to 50 along the lure's height and from 5 to 100 along its length. The scale shape can range from V-shaped to U-shaped. The scales can be arranged in a line or offset laterally.The height of the anterior bulge can range from 10% to 100% of the scale length. The angle of the bulge, measured from the scale tip, can range from 40 degrees to 90 degrees (3b). The surface of the bulge can be flat or concave. [4] Rubber fishing lures (delayed sinking) characterized byThe lateral drag fins (4) on the head of the soft plastic lure slow its descent due to their orientation against the direction of water flow. The position of the drag fins can vary between 10% and 40% of the lure's total length, viewed from the head end. The shape of the drag fins can be rounded or pointed. The angle of the drag fins can vary from 35 degrees to 90 degrees (4a) to the lure's longitudinal axis. The drag fins can be flat or concave towards the front. Viewed from the side, the drag fins can be inclined at an angle of 35 degrees to 90 degrees, thus giving them the function of a scissor plate. The size of the drag fins can be as large as the largest cross-section of the soft plastic lure. [5] Rubber fishing lures (delayed sinking) characterized byThe drag lip mounted on the head slows the sinking of the soft plastic lure due to its shape. The lip can be positioned on the underside of the lure, extending from the front of the head to 35% of the lure's length towards the tail. The shape of the drag lip can range from horizontally flat to U-shaped. The angle of the drag lip can vary from 10 degrees to 90 degrees (5a) to the longitudinal axis of the soft plastic lure. The size of the drag lip can vary from very small to one-quarter the size of the soft plastic lure. [6] Rubber fishing lures (delayed sinking) characterized byThe falling speed can be further reduced by a crescent-shaped fin (6) on the tail peduncle. The resulting increase in kinetic energy also improves the overall action of the soft plastic lure. The tail peduncle with the crescent-shaped fin can be straight or curved downwards in a circular arc towards the tail end. The arc of the arc can range from 0 degrees (straight tail peduncle) to 120 degrees (forward-curving crescent). The underside of the crescent can be reinforced by a thickening. The tail end of the soft plastic lure can comprise between 20% and 60% of the lure's total length, measured from the last rib.
