Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a fishing towboat, and more specifically, to a fishing towboat for storing fish caught floating on the water surface during sweetfish fishing in rivers. .

(Prior art) Conventionally, as described in Japanese Utility Model Application Publication No. 144459/1983, a fishing boat has been constructed using a boat with a fish input port on the top wall and a storage chamber for live fish inside. A lid for closing the inlet is pivotally supported inwardly on a wall, and a spring is provided between the lid and the upper wall for biasing the lid in a closing direction. , the input port can be opened by simply pressing the lid inward, and a plurality of latching holes for latching tow cables are provided in the front part of the boat body in the pulling direction. It is known that they were placed in a row.

By the way, this towing boat floats on the surface of the water mainly when fishing for sweetfish after entering the water, and when moving underwater to change fishing spots, the towing boat is pulled on the tow rope and moved while floating on the water surface. Let it happen.

(Problem that the invention aims to solve) However, in conventional towing boats, a hook hole for hooking a tow line is provided at a fixed position on the boat body, and the tow rope hooks to this hook hole. The length of the boat is a certain length, and the towing position is also almost fixed, so when the boat enters the water and moves, the strength of the water current changes the buoyancy of the boat relative to the water surface, causing it to sink too much. ,
The top of the boat was sometimes exposed to the water surface.

In other words, if the water current is rapid, the amount of water flowing over the top of the boat will increase, causing the boat to sink too much, and in a pool with little current, the boat will not sink and the top will sink. As it becomes exposed above the water surface, the water temperature inside the containment chamber increases,
There was a problem in which the vitality of the live fish inside decreased due to poor activation of the water.

In addition, if the main body of the boat sinks too much into the water, the towing load becomes large, which increases the burden on the angler, and the lid body swings inward greatly, opening the fish input port wide and causing damage to the inside of the storage chamber. A problem arises in which live fish escape from the input port to the outside.

The purpose of the present invention is to make it possible to sink the boat body by a predetermined amount by simply changing the hooking position of the tow rope to the boat body in accordance with the water flow.

(Means for Solving the Problems) Therefore, the present invention has a boat body which has a fish input port 11 on the upper wall and a lid body 2 for closing the input port 11, and has a live fish storage chamber 12 inside. A plurality of hooking portions 15 for hooking the tow rope 3 are provided at the front portion of the puller 1 in a vertical direction.

(Function) When fishing for sweetfish in the water, the hooking position of the tow rope 3 to the boat body 1 is changed in response to the water current, and in the pool, the tow rope 3 is moved to the uppermost hooking point. By latching, the boat body 1 can be sunk by a predetermined amount, and in the case of rapid water, the boat body 1 can be made to sink by hooking the tow rope 3 to the lowest latching part. It is possible to achieve the same amount of subsidence as in the case of a pond without too much.

(Example) In the figure, 1 is a hollow boat body which has a fish input port 11 on the front side of the upper wall 1a and a storage chamber 12 for live fish inside. An inlet 13 is provided, and an outlet 14 is provided at the rear of the inlet 11 in the upper wall 1a, so that fresh water can be introduced into the storage chamber 12.

Further, 2 is a lid body that closes the input port 11 from the inside, and is a lid body that closes the input port 11 in the upper wall 1a.
It is pivotably supported inwardly at the front part of the first part.

A spring 3 is interposed between the upper wall 1a and the lid 2 and biases the lid 2 in the closing direction.

However, in the embodiment shown in FIGS. 1 to 3,
A plurality of hooks 15 are provided at the front of the boat body 1 in the pulling direction, penetrating through the front wall 1b, and for hooking the tow rope 3, and are disposed in vertical positions.
A slide hole 16 extending in the vertical direction is provided at one side of the hooking portion 15, and the slide hole 16 and each of the hooking portions 15 are connected to each other.
They are communicated with each other through a communication groove 17 having a width smaller than the diameter of the hole 5. Note that, as shown in FIG. 2, a pair of the hooking portions 15 are provided on both sides of the widthwise center position of the front wall 1b, but they may also be provided elsewhere, for example, only at the widthwise center position.

Further, the hooking part 15 has, for example, an insertion hole 41a for the tow rope 3 as shown in FIGS. , a neck portion 42 movable within the communication groove 17; and a diameter larger than the neck portion 42 and the hook portion 1;
5, and a retaining portion 44 having a larger diameter than the trunk 43, the tow rope 3 is inserted into the insertion hole 41a of the cable receiver 4. Then install it. Furthermore, this tow rope 3
consists of a base part 3a that is inserted into the insertion hole 41a and tied in a ring shape, and a tip part 3b that is connected to the middle of this base part 3a. It's summery.

Further, a fish inlet portion 10 of the upper wall 1a of the illustrated boat body 1 is formed separately from the boat body 1, and the lid body 2 is pivotally supported on this fish inlet portion 10. The rear part of 10 is pivoted to the upper wall 1a via the hinge 5, and the front part is
A thin hinge 21 and a pair of knobs 22 and 23 are provided at the front part of the fish inlet portion 10 and are fixed to the inside of the upper wall 1a.
By holding 2 and 23 and bending the thin hinge 21, the upper wall 1 of the fish inlet portion 10 is
It is designed so that it can be disengaged from a.

By doing so, for example, when supporting the rope receiver 4 on the hooking part 15, the fish input port 10 is opened and the rope body 4 is inserted into the boat body 1 through this opening, Slide the head 41 into the hole 1
6 to the outside of the boat body, and a communicating groove 17
The trunk portion 43 can be supported by the hooking portion 15 via.

Further, at the lower part of the front wall 1b of the boat body 1,
A finger hook 18 is provided at the center portion in the width direction, so that the finger hook 18 and the upper surface of the front portion of the boat body 1 can be held with one hand. By doing so, the front part of the boat body 1 can be held and the fish can be thrown into the inlet 11 and taken out from the inlet 11, making it easy to put in and take out the fish.

Further, at a rear portion of the input port 11 in the boat body 1, there is provided a water introduction chamber 6 having an upright wall 61 projecting outward from the lid body 2 and communicating with the storage chamber 12. In addition to providing the above-mentioned rising wall 6
1 is provided with a water inlet 7 that opens to the outside, so that when the towboat is pulled and moved, even if the top surface of the towboat is covered with water, the water flowing on the top surface of the lid body 2 is diverted from the upright wall 61. The water flows into the storage chamber 12 from the water introduction port 7 through the water introduction chamber 6, thereby reducing the impact acting on the lid 2 and preventing the lid 2 from opening wide.

When the tug boat constructed as described above enters water in a river to fish for ayu, it floats on the water surface and throws the caught fish into the storage chamber 12 from the fish input port 11.
Also, when fishing for sweetfish, the hooking position of the tow rope 3 to the boat body 1 is changed depending on the water current at the place to be moved.

Therefore, when fishing for sweetfish by moving through a pool with little water flow, the tow rope 3 is hooked to, for example, the uppermost hook 15a, so that water can easily pass over the boat body 1. Therefore, when fishing for sweetfish in a pool, it is possible to prevent the water temperature in the storage chamber from rising and the water from becoming less active.

Furthermore, when traveling through rapids for sweetfish fishing, the tow rope 3 is hooked to, for example, the lowest hooking portion 15b to prevent the boat body 1 from bending too much.

Therefore, when fishing for sweetfish in rapids, the towing load can be reduced, the towing can be done easily, and the fish input port 11 can be prevented from opening wide.

Moreover, when changing the hooking position of the tow rope 3, for example, the rope receiver 4 supported on one of the hooking parts 15
is pressed inward of the boat body 1 to position the neck portion 42 on the hook portion 15b. In this state, the neck portion 42 is moved laterally along the communication groove 17, and then moved upward along the slide hole 16. The tow rope 3 is moved to the side or downward side, further moved along the communication groove 17, and pulled outward with the neck portion 42 in the desired hooking portion. It is latched onto a desired latching portion 15.

In the embodiment described above, the hole penetrating the front wall 1b is used as the hook part 15, but in addition, for example, a rising piece may be provided on the front wall 1b, and this rising piece may be formed of a through hole. A hook part may be provided, or a plurality of protrusions may be provided on the front wall 1b or the rising piece,
These protrusions may be used as the hooking portions 15, and the structure of the hooking portions 15 is not particularly limited. In short, any structure may be used as long as the tow rope 3 can be hooked in a variable manner. Moreover, the above-mentioned hooking part 15
In addition to being provided on the front wall 1b, it may be provided on the side wall at the front of the boat body 1.

(Effects of the invention) As described above, according to the invention, the hooking position of the tow rope 3 to the boat body 1 can be adjusted in accordance with the water flow.
When moving into a pool, the boat body 1 can be lowered by a predetermined amount by hooking the tow rope 3 to, for example, the uppermost hook. 1 can be cooled by the water that can be overcome, and when moving into rapids, the tow rope 3 can be hooked to the lowermost hook, for example, to prevent the boat 1 from sinking too much. This makes it possible to sink the boat body 1 by a predetermined amount and easily tow it, and also prevent the fish input port 11 from opening wide.
