Description

Tftrhniπal Field of the InvsπHnπ

This invention relates to a wobbler comprising a casing composed of two mirror-inverted shell parts, which casing delimits a long narrow cavity and includes means for connecting one or more hooks as well as a line and/or swivel.

Prior Art It is previously known (see US 2 910 800, FR 2 675 339, US 2 937 467 and US 2 805 511) to form fishing-lures in the form of spinners or spinner-like lures in such a way that they may accommo¬ date a consumable tablet which may emit scent and/or gas with the purpose of attracting game fishes. However, previously known wobbler-lures have not been able to make use of this pos¬ sibility.

Objects and Features of the Tnvention

A primary object of the present invention is to create a wobbler which not only may accommodate a scent- or gas emitting tablet, but also guarantees an effective emission of scent. Another object is to create a wobbler which, in spite of the possibility of accommodating a scent tablet, is construction- ally simple and, accordingly, cheap to manufacture. Further- more, the tablet should be able to be loaded in the wobbler in an easy and quick way.

According to the invention, at least the primary object is attained by the features defined in the characterizing clause of claim 1. Preferred embodiments of the invention are furthermore defined in the dependent claims.

Detailed Description of Preferred Embodiments of the Invention In figures 1 and 2, reference numeral 1 generally desig- nates a frame-forming casing which is composed of two shell parts 2, 2' which are permanently connected to each other. In the shown embodiment, a frontal, detachable nose part 3 is also included in the wobbler. As will be closer described below, the frame casing 1 is, on the outside thereof, formed with wave formations 4 extending transverse to the length extension of the frame casing. The difference between the embodiments according to figures 1 and 2 is that said wave formations 4 in the embodiment according to fig 1 extend, in the main, perpen¬ dicularly to the longitudinal axis, while the corresponding wave formations in the embodiment according to fig 2 are oblique in relation to the longitudinal axis. In fig 2, the frame casing is shown supplemented by a number of hooks 5. Said hooks are coupled to fastening loops 6 in the form of stiff metal wires . A corresponding fastening loop 6 ' at the front end of the frame casing serves as a fastening for a fishing-line or swivel .

Reference is now made to figures 3 to 6 which in detail show the nature of the interior of the frame casing 1. The shell part 2 is shown in fig 3, while the shell part 2' is shown in fig 4. In practice, each one of said shell parts is made of casted or injection moulded plastics. Each shell part is in the form of a cross-section-wise arc-shaped or vaulted, relatively thin wall which is terminated by upper and lower plane edge portions 7, 8 of which the first-mentioned portion is located in the back part of the finished wobbler, while the last-mentioned portion is located in the belly part thereof. Thickened, reinforcing material portions 9 are provided in con¬ nection with said edge portions 7, 8. More precisely, four such reinforcement portions are formed in connection with the back edge 7, while three reinforcement portions 9 are provided in connection with the belly edge 8. Holes or recesses 10 are formed in the different reinforcement portions 9 of the shell part 2. The reinforcement portions 9 included in the shell part 2' are, on the other hand, formed with protruding fixing tenons 11 which, when assembling the two shell parts, are brought into engagement with the holes 10. Furthermore, two pairs of mutu¬ ally separated projections 12 are provided in connection with the belly edge 8, which projections protrude a bit in a direc- tion inwards from the belly edge. A semi-circular groove 13 is formed in each such projection. Similar, semi-circular grooves 14 are also provided in the proper belly edge portion 8, more precisely in the area between two adjacent projections 13. As shown in fig 3, said grooves 13, 14 have the purpose of accom- modating U-shapedly bent metal wire pieces which form the above-mentioned fastening loops 6.

A longitudinal intermediate wall 15 is included in each one of the two shell parts 2, 2', which wall, when said shell parts are assembled to an integrated casing, separates the interior of the casing into two chambers, viz. an upper chamber 16 intended to be filled with air, and a lower chamber 17 (see also fig 2) . Water may flow through said lower chamber 17 from a front inlet hole to a rear outlet hole 18. In the example of embodiment in question, which has a detachable nose part 3, the inlet hole 19 for the water is recessed in the proper nose part which, in turn, in a mounted state, is arranged to close an opening 20 at the front end of the frame casing. Each interme¬ diate wall or intermediate wall portion 15 extends, in the main, along the whole length of the frame casing, more pre- cisely from the rear outlet hole 18 to a frontal, thickened reinforcement portion 9 ' . The intermediate walls 15 are located in such a way that they, in an assembled state, separate the interior of the casing into two approximately equally large chambers. A cylinder-shaped wall portion 21 is provided on the top or back side of each intermediate wall, which wall portion forms a cavity for one or more sound-generating, stiff bodies, such as shots (not shown) when the shell parts are assembled. Furthermore, a protruding cylindric body 22 is provided on the inside of the shell part 2, in the free end of which body a fixing hole opens. A corresponding cylindric body 22' is pro¬ vided on the inside of the shell part 2, but this cylindric body ends in a protruding fixing tenon. When the shell parts are assembled, said cylindric bodies 22, 22' form a cross bar which in fig 2 is designated 23. As may be seen in fig 2, said cross bar 23 has the purpose of positioning a tablet 24 which may emit scent or gas agents.

It should also be noted that a U-shaped, stiff metal wire 6 is mounted at the rear end of the shell part 2. The U- wire 6' for the swivel of the fishing-line is mounted in grooves in a pair of fastening blocks 25 provided underneath the above-mentioned reinforcement portions 9' .

Joining the two shell parts 2, 2' is in practice most suitably carried out by gluing (or heat welding) while simulta- neously pressing the two parts together. In doing so, a very precise positioning of the shell parts in relation to each other is achieved by means of the fixing tenons 11 which are pressed into the holes 10. As may be seen in fig 8, the nose part 3 includes two separate side pieces 26, which, on the insides thereof, have first guide elements 26' in the form of protruding beads which are arranged to co-operate with other guide elements in the form of grooves 27 between the reinforce¬ ment portions 9' and the fastening blocks 25. Thus, the nose part 3 may be pushed on the fastening blocks and, in a maxi- mally inserted position, be held in place by means of a nib 28 which snaps into a corresponding hollow on the top side of the nose part. In this state, the nose part covers the opening 20 through which the scent tablet 24 may be inserted in the cham¬ ber 17. It should also be noted that a spoon 29, which in the usual way is required for a wobbler to be drawn down into the water, is mounted on the nose part 3 in the example according to figures 1 to 8. The described wobbler works in the following way. Before usage, the nose part 3 is removed so that one or more scent- or gas-emitting tablets 24 may be inserted in the lower chamber 17. Then, the intake opening 20 is sealed by the fact that the nose part is mounted in place again. When the wobbler is thrown out in the water, water may flow in through the inlet hole 19 and fill the lower chamber 17. By the fact that the upper cham¬ ber 16 is still air-filled, the wobbler will float, more pre¬ cisely in an upright position in which the chamber 16 is located above the chamber 17. Then, when the wobbler is set in motion by means of a pulling force in the fishing-line, the spoon 29 guarantees that the wobbler dives down in the water. In doing so, the tablet 25 will be flushed around by water flowing through the chamber 17 from the inlet hole 19 to the outlet hole 18; all this in guaranteeing that scent agents and/or gas bubbles are emitted through the rear outlet hole 18. By the occurrence of the cross bar 23, it is guaranteed that the scent tablet 24 is not wedged into and chokes up the rear, narrowing section of the chamber 17. Not only the emission of scent agents or gas bubbles contributes to the power of attrac- tion of the described wobbler, but also the sound-generating elements accommodated in the cavity formed by the cylindric walls 21.

In the embodiment according to figures 9 and 10, the special, detachable nose part 3 according to the above- described embodiment is missing. Thus, in this case, the intake opening 20 for the tablet also serves as an inlet hole for the water which is to flush through the lower chamber 17. In doing so, the requisite spoon 29' is made integrally with the proper frame casing. More precisely, the spoon 29' has a rear fasten- ing element 30 which is inserted and glued in a seat 30' in the assembled frame casing. In connection with said seat, a head 31 is provided which makes unintentional removal of a scent tablet inserted in the chamber 17 more difficult. In practice, the bore extending between the proper intake opening 20 and the head 31 may be of diameter which is only a little larger than the diameter of the tablet .

In practice, the surface of the frame casing may be pro¬ vided with wave formations 4, as shown in figures 1 and 2. More precisely, the entire surface of the frame casing, apart from the front nose portion, is formed with such wave formations 4. Said wave formations may be obtained in different ways. When frame bodies made of plastic are involved, said formations are most suitably realized by casting or injecting the plastic material in a moulding tool, the shape of which tool corre¬ sponds to and gives the desired wave shape. However, it is also conceivable to make the two shell parts forming the casing by another material, e.g. balsa wood. In this case, the wave for¬ mation may be obtained by turning or cutting. An effect of the wave formations 4 is that the specific surface on the outside of the frame casing expands compared to a completely smooth external surface. However, the most impor¬ tant effect is that light hitting the outside of the frame cas¬ ing is reflected more all-round than light hitting a smooth surface. Exactly this improving reflection ability of the lure has proved to give an extremely improved visibility when the lure is brought forward in water.
