Abstract
The object of the present invention is a wobbler with adjustable gravity center location having a hollow opening with a threaded sleeve in a casing containing a movable threaded exchangeable additional weight for changing the height of the location of gravity center of the casing relative to its central axis.
Claims

DETAILED DESCRIPTION OF THE INVENTION
[0018] A wobbler with adjustable gravity center location comprises casing 1 that is made from floating material, e.g., wood. The front part of casing 1, mirror 2 in fishing terminology, is a surface that is tilted upwards and to the rear. The tilting angle of mirror 2 is within 40 to 50 degrees from mirror 2 surface and the central axis 3 of the casing 1, based on the desired diving depth. Mirror 2 has loops 4 and 5 for attachment of fishing line 6. Loops 4 and 5 are located on the large half-axis of the ellipse-shaped mirror above its center (above the central axis 3). The lower loop 4 is located at ⅓ and the top loop 5 is located at 2/3 of the distance of the longer half-axis from the center of the ellipse. At the tail of casing 1 there is a loop 7 for attachment of fishing hook 8. Under the belly of the casing 1, on the vertical axis 9, there is a loop 13 for attachment of fishing hook 14.
[0019] In preferred embodiment, at the location of the gravity center determined longitudinally on the central axis 3 of the casing 1 loaded with fishing hook 8, a hole 10 towards the vertical axis 9 has been drilled from top with depth 0.65 to 0.75 of the diameter of the casing 1, and a sleeve 11 with inner thread has been placed therein. The hole 10 may be drilled into casing 1 also from the bottom or through the whole diameter of casing 1. In the sleeve 11, there is an additional weight 12 with specific gravity made of material meeting environmental requirements (e.g., stainless steel) that can be shifted by threaded joint, with a recess on the top surface for shifting the weight by an appropriate tool (e.g., an Allen key). By shifting the changeable additional weight 12 also the height of the gravity center of the wobbler relative to the central axis 3 of the casing 1 changes. Depending on the height of the location of the gravity center, the nature of wobbler balance changes.
[0020] The additional weight 12 can be exchanged for one from the set of additional weights with different masses that the fisher has with them on the fishing trip, the mass depending on the dimensions of the wobbler itself, being within the limits of 0.2 to 0.25 of the mass of the casing loaded with fishing hooks 8 and 14.
[0021] The solution makes it possible for the fisher, relying on their knowledge, skills and experience, to use intermittent winding speed of the fishing line 6 in the event of indifferent and unstable balance position and thereby also change the oscillating movement frequency, amplitude and other play manners of the wobbler. In order to achieve the required diving depth of the wobbler, a fisher may combine the winding speed of fishing line 6 and the height of the loop used for attaching it.
