DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to the structure of a fishing lure, particularly to the crank-bait lure classified as a lure for aiming at deep spots.
BACKGROUND ART
The plug lure, for example, a crank-bait lure requires a diving lip (diving plate) and a large balance-weight within its lure body. In a lure which is designed to be able to aim at deep spots, the diving lip must be enlarged. Since the shape factor of such an enlarged lip increases the air resistance against the lure body, it will be difficult to get a long flying distance of the lure body.
On the other hand, in order to perform only a long casting without aiming at deep spots, a balance-weight 120 would be fixed in the rearmost portion of the lure body 110 as shown in FIG. 1. The lure whose centroid is set in the rear portion of its lure body 110 cannot be influenced by the shape factor of the lip. Thereby, the lure may be cast for a long distance. However, when the balance-weight 120 is fixed like this, the centroid is set in the rear portion as described above. This results in a problem that the crank-bait lure of this type could not go underwater deeply, and that a swimming balance would be lost. Thus, in the crank-bait lure provided by the prior art, it is difficult to make a casting performance compatible to an underwater cruising performance.
There is also known a lure of another type, in which a magnet provided in the front portion of the lure body, can draw and hold a balance-weight by its magnetic force. In case of this lure, its mechanical structure will be more complicated, and the number of parts is increasing.
An object of the present invention is, in view of the above problems, to provide a mechanism for moving and holding a balance-weight, which can provide a casting performance compatible to an underwater cruising performance, and give superior functions in the lure.
Another object of the present invention is to provide a mechanism for moving and holding a balance-weight, which is constructed simply, and that can hold the balance-weight in an optimum position, to thereby obtain its appropriate pose for under water cruising.
SUMMARY OF THE INVENTION
A mechanism for moving and holding a balance-weight in the lure in accordance with the present invention, comprises a lip mounted at the front end portion of a lure body and a balance-weight incorporated in the lure body, wherein the balance-weight is adopted to be movable along a longitudinal direction of the lure body. Particularly, the balance-weight can move in a longitudinal direction by rolling on a guide having a pocket provided in the front end portion thereof, and the balance-weight can be held within the pocket.
Since the balance-weight is movable in a longitudinal direction, it moves to the rearmost portion of the lure body during casting, thereby a long casting can be achieved. After casting, the balance-weight then moves to the frontmost portion of the lure body in which a optimum centroid for underwater cruising is given. Thereby, a superior casting performance is obtained.
In this case, as there is provided the pocket in the front end portion of the guide for guiding the balance-weight, it can be held within the pocket, thereby the lure body maintains its constant pose so that a good swimming balance for going underwater is obtained.
In accordance with another aspect of the present invention, the lure comprises a lip mounted at the front end portion of a lure body and a balance-weight incorporated in the lure body, wherein the balance-weight is adopted to be movable along a longitudinal direction of the lure body by rolling on a guide, and a holder having a cover is provided in the front end portion of the guide so that the balance-weight can be held within it. Particularly, the holder is formed as a relatively deep recess.
In this kind of lure as afore-mentioned, the balance-weight is generally fixed in the rearmost portion of the lure body to set its centroid in the rear of the lure in order to perform a long casting. In accordance with a mechanism pro
