Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing light device used to attract fish on a fishing boat such as a squid fishing boat.

[0002]

2. Description of the Related Art When a fish-collecting light installed on a fishing boat is turned on at night, the light is partially obstructed by the deck of the hull, creating light and darkness in the sea. It is used to increase the catch by catching fish by utilizing the habits gathered.

[0003] As a fishing boat equipped with the above-mentioned fishing light, FIG.
(A) As shown schematically in (b), a mast 3 is erected at the front and rear positions of the deck 2 on the hull center line of the hull 1 so as to face each other, and a wire is provided between the upper ends of the front and rear masts 3. In general, a required number of fish collecting lights 5 are suspended from the wire 4 and supported.

[0004]

However, when rolling occurs on the hull 1, the fishing light 5 also rolls via the mast 3 and the wire 4, so that the boundary between light and dark portions in the sea fluctuates. And affect the catch.

More specifically, as shown in FIG.
However, when the fish gathering light 5 rolls around the center of gravity G as shown by a two-dot chain line (indicating a case of 30 ° to the starboard side), the fish catching light 5 also rolls. The line greatly changes from A-B to A'-B '. As described above, when the boundary line of the light and dark area by the fish-collecting light 5 moves, the fish also moves along with it, so that in order to efficiently catch the fish, the input position of the hook or the net is changed every moment. It must be done, but it is very difficult to do this from the hull 1 which is rolling and therefore the target catch cannot be obtained.

[0006] Therefore, the present invention is intended to increase the catch by preventing the fishing light from rolling even if the boat body rolls.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a mast is erected at a position on a hull center line on a hull center line, and a rail is fixed to an upper end of the mast in a lateral direction. Then, on the rail, a movable carriage is placed so as to be movable in the left-right direction, the movable carriage is supported by a rod arranged to extend in the front-rear direction, and a fishing light is attached to the rod.
In addition, left and right guide pipes having lower ends communicating with communication pipes to inject the liquid to a required height level therein are erected below the left and right ends of the rail, and the liquid level in the left and right guide pipes is set up. Then, a float having a required weight is suspended by a rope and floated, and each of the ropes is guided to the movable carriage via an end position of the rail, and is connected in tension.

When the ship sways, the mast, rails, left and right guide tubes, etc., sway together. However, since the liquid level in the left and right guide tubes is maintained equal, the movable bogie becomes floating and Since it moves relative to the rail through the displacement of the rope and is kept at the same position, the boundary line of the light and dark portion by the fish catching light can be created at almost the same position as when the hull is at a standstill.

A combination of a mast, a rail, a movable carriage, left and right guide tubes, a float, and a rope,
By arranging a plurality of sets at the position on the hull center line and connecting the movable carts arranged in front and rear with rods, it is possible to stabilize the movement of the movable carts, so that the movable carts can be easily applied to a large fishing boat. Become.

Further, by forming the rail in an arc shape having a radius of curvature centered on the center of gravity of the hull, vertical displacement of the movable bogie when the hull swings can be suppressed, and the vertical direction of the fishing light can be reduced. Position can be almost constant,
It is more advantageous.

[0011] Further, by providing a structure in which a throttle device for regulating the movement of the liquid inside is installed at a position on the way of the communication pipe for communicating the left and right guide pipes, the movement cycle of the liquid acting as the vibration-reducing mass is provided. Can be adjusted to the natural period of the hull.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 (a) and 1 (b) show an embodiment of the present invention. In a fishing boat similar to that shown in FIGS. 7 (a) and 7 (b), a hull 1 A mast 3 having a required height is erected at a central position of the mast 3.
On the upper end of the hull 1, a rail 6 curved to an arc shape having a radius of curvature about the center of gravity G of the hull 1 and having a length shorter than the hull width.
And fix the rail 6 to the left and right (side)
A movable carriage 7 is mounted on each rail 6 so as to be movable in the left-right direction, and a central portion of a rod 8 disposed on the movable carriage 7 so as to extend in the front-rear direction is cantilevered. The rod 8
A plurality of fish collecting lights 5 are attached at appropriate intervals.

In addition, the rails 6 are located at the lower ends of both ends.
Left and right guide tubes 10a and 10b are erected such that their lower ends are communicated by a communication tube 9 so that a liquid 11 such as water can be injected into the inside to a required height level.
The floats 12a, 12b having a required weight and also serving as weights are floated on the liquid surfaces in 0a, 10b in a state of being suspended by a rope 13, respectively.
At the left and right ends of the movable carriage 7, the sheaves 14 provided as guide members at the left and right ends of the rail 6 are guided and connected in tension, so that the weight is balanced, and the hull 1 rolls. The left and right floats 12a, 12b are displaced in the guide tubes 10a, 10b by the change in the liquid level in the guide tubes 10a, 10b accompanying the movement of the movable carriage 7 with respect to the rail 6 by the displacement of the left and right floats 12a, 12b. By moving the movable cart 7 at a fixed position by relative movement in the direction, the lateral movement is not transmitted to the fishing light 5.

In a calm state where the hull 1 does not roll, as shown in FIG. 2, the boundary line of the bright and dark portions by the fish catching light 5 is as shown by AB. Here, as shown by the two-dot chain line,

), The mast 3, the rails 6, and the guide tubes 10a, 10b are also slid and displaced rightward with the hull 1, but the guide tubes 10a, 1
Since the liquid 11 in Ob can flow freely through the communication pipe 9 at the lower end, the level of the liquid surface in the left and right guide pipes 10a and 10b becomes equal. In this case, the liquid level in the guide tube 10a drops and the liquid level in the guide tube 10b rises, so that the float 12a descends in the guide tube 10a and the float 12b rises in the guide tube 10b. Therefore, the movable cart 7 is given a moving force to the left via the left and right ropes 13. On the other hand, since the rail 6 is displaced to the right integrally with the hull 1 as described above, the movable bogie 7 moves relative to the rail 6 by the angle at which the hull 1 rolls, and as a result, the vertical It will be kept at the origin position on the line.

In the above, the rail 6 is the center of gravity G of the hull 1
Because it is formed in an arc shape with a radius of curvature centered on
The height position of the movable cart 7 in the vertical direction can be maintained substantially constant. For this reason, the boundary line of the light and dark portion by the fish-collecting light 5 is like A1-B1, and hardly deviates from the boundary line AB of the light and dark portion in a quiet state.

FIG. 3 shows that the roll angle of the hull 1 is 20 °.
FIG. 4 shows a case where the roll angle of the hull 1 is 30 °, and FIG.
Both 2-B2 and A3-B3 do not significantly deviate from the boundary line AB of the bright and dark portions in a calm state. In particular, when comparing the case of the present invention shown in FIG. 4 and the case of the conventional example shown in FIG. It can be seen that the deviation from the line AB is extremely small.

In the above description, the left and right guide tubes 10
a and 10b are connected at their lower ends by a communication pipe 9,
Since the liquid 11 inside moves to the left and right according to the roll of the hull 1, a mechanism as a rocking device can be exhibited, and the roll of the hull 1 can be reduced.

Next, FIG. 5 shows another embodiment of the present invention. In a configuration similar to that shown in FIGS. 1A and 1B, the mast 3, the rail 6, the sheave 14, and the movable carriage 7 are used. ,
Left and right guide tubes 10a, 10 communicated by a communication tube 9.
b, floats 12a, 12b and ropes 13 are arranged in two sets facing each other at the front and rear positions on the center line of the hull, and movable carts 7 located at the front and rear are connected by rods 8. In addition, sheave 14, float 12
a, 12b and the rope 13 are not shown.

The structure shown in FIG. 5 can stabilize the entire structure and stabilize the movement of the movable carriage 7, so that it is particularly advantageous to employ the hull 1 having a long captain. Becomes

FIG. 6 shows still another embodiment of the present invention. In the embodiment shown in FIGS. 1 (a), 1 (b) and 5, the distance between the lower ends of the left and right guide tubes 10a, 10b is shown. The throttle valve 15 as a throttle device is assembled at a position in the middle of the communication pipe 9 for communicating with the throttle valve.

As shown in FIG. 6, the left and right guide tubes 10
When the throttle valve 15 is assembled in the middle of the communication pipe 9 of a and 10b, the opening degree of the communication pipe 9 can be adjusted by the throttle valve 15, so that the motion cycle of the internal liquid 11 due to the rolling is determined by the hull 1 It can be adjusted to the natural period, and the function as the rocking device can be made to work more effectively.

In the above embodiment, the rail 6 is
Although the case where the hull 1 is formed in an arc shape with a radius of curvature centered on the center of gravity G is shown, the shape is not limited to this, and may be an inverted arc, or an ellipse, a multi-folded circle, a letter, a straight line, or the like. In this case, the movable trolley 7 is slightly displaced up and down when the hull 1 rolls, but does not swing largely left and right as in the conventional case, It is effective because it does not move greatly to
Further, the sectional shapes of the guide tubes 10a and 10b and the communication tube 9 can be arbitrarily selected. Further, in the embodiment, the mast 3 is set so as to straddle the communication tubes 9 for the left and right guide tubes 10a and 10b. The case of standing is shown, but mast 3
The communication pipe 9 may be curved so as to avoid the root of the mast 3, and in the embodiment of FIG. 5, the mast 3, the rail 6, the movable carriage 7, the guide pipes 10a and 10b,
