Description

[Detailed description of the invention] (Field of industrial application) The present invention is a fishing depth reading device, specifically, it is a fishing depth reading device that measures the length of fishing line pulled out from the spool of a fishing reel, mainly when fishing on a boat. This invention relates to a fishing depth reading device designed to read underwater depth.

(Prior art) Conventionally, this type of depth reading device has no design registration.
The one shown in No. 411048 is known. In this conventional depth reading device, a rotor is rotatably supported on one side of the housing, and an annular pincushion groove is provided on the outer peripheral surface of the rotor. The intermediate portion of the drawn fishing line is wound once, and a counter for counting the number of revolutions of the rotor is built into the housing so that the underwater depth can be read.

Incidentally, the bobbin winding groove is provided to prevent the wound fishing line from coming off the outer peripheral surface of the rotor in the axial direction outward, and the groove width at the open end of the bobbin winding groove is determined by the width of the knot in the fishing line. Since the fishing line is wound in one plane without considering the thickness of the fishing line, if there is a knot in the middle of the fishing line, the knot will be completely inserted into the thread winding groove with plenty of room. It was on.

(Problems to be solved by the invention) However, according to the conventional depth reading device in which the knot of the fishing line is completely inserted into the bobbin groove,
The entry position of the entry side yarn that enters the bobbin groove and the exit position of the entry side yarn that advances from the bobbin groove are as follows:
Since the positions are the same with respect to the center of the rotor, when the knot advances from the bobbin groove, if the knot gets caught on the entry side thread at a position slightly before the advance position, this catch will occur. Without coming off, the fishing line will be pulled by a tension force to the fishing line's advancing side with respect to the bobbin winding groove, and as a result, a double portion will be created in the middle of the fishing line, making it impossible to accurately read the depth. Further, there was a problem that the fishing line in the double portion became tangled.

The purpose of this invention is that there is a knot in the middle of the fishing line,
Even if this knot catches the entry side thread, it is possible to remove the catch.

(Means for Solving the Problems) Accordingly, the present invention has a housing 2 that freely supports a rotor 3 that winds the middle part of a fishing line pulled out from a spool of a fishing reel, Counter 4 that counts the number of rotations of rotor 3
In this fishing depth reading device, a fishing line winding groove 32 is provided on the outer circumferential surface of the rotor 3, and the groove width H at the open end of the fishing line groove 32 is determined by the width of the knot in the fishing line. This is a range that allows interference to be prevented.

(Function) If there is a knot in the middle of the fishing line, this knot is prevented from intervening in the bobbin groove 32, and the knot is prevented from entering the bobbin groove 32.
In contrast, the entry side thread moves in contact with the bottom surface of the bobbin groove 32, so the advancing position of the knot and the entering position of the entry side thread are as follows: It is displaced in the radial direction with respect to the center of the rotor.

Therefore, when the knot advances from the bobbin groove 32, even if it is caught on the entry-side thread, a return force acting on the entry-side thread inward in the radial direction of the rotor 3 is applied to the knot. However, this returning force causes the entry side thread to be unlatched from the knot.

(Example) The illustrated depth reading device has one mounting leg on the bottom side.
A rotor 3, which winds the middle part of the fishing line pulled out from the spool of a fishing reel, is freely rotatably supported on the front surface of the housing 2, which has a hollow interior. A counter 4 for counting is built into the housing 2, and a drive shaft of the counter 4 projects outward from the front surface of the housing 2, and a driven tooth provided on the rotor 3 is attached to the shaft end of the drive shaft. 31, the number of revolutions of the rotor 3 counted by the counter 4 is converted into the drawn-out length of the fishing line and displayed, and this display value is displayed in a display window ( (not shown).

In the embodiment shown in FIGS. 1 to 4, the thread winding groove 32 for the fishing line is provided on the outer peripheral surface of the rotor 3, and the groove width H at the open end of the thread winding groove 32 is set to The width was set so that the intervention of knot A could be prevented.

In the above configuration, the thread winding groove H has a groove width H of 1.4 mm at the open end and a groove depth of 0.3 mm for a fishing line having a thread diameter of 0.5 to 0.6 mm, for example. In this case, the groove width H is 2.8 times the groove width for a fishing line with a thread diameter of 0.5 mm, but the thickness of the fishing line at knot A is 3 times the thread diameter when tied in a general knot. Therefore, the knot A can be prevented from intervening in the thread winding groove 32.

In addition, since the knot A of the fishing line is generally three times the diameter of the fishing line as described above, the groove width H is
The width is set to be less than three times the thickness of the fishing line, assuming the thickness of the fishing line used when fishing by measuring the depth. Further, the depth of the bobbin groove 32 may be, for example, deeper than the thickness of the fishing line.

Further, in the illustrated embodiment, a wide groove 33 is provided on the outer periphery of the rotor 3, which is wider than the peg groove 32 and allows the knot A to intervene. In addition, a plurality of guide surfaces 34 for guiding the fishing line from the wide groove 33 to the bobbin groove 32 are provided at predetermined intervals in the circumferential direction. The number of this guide surface 34 may be one.

Further, in the figure, 5 is a cover body provided around the outer circumference of the rotor 3, 6 is an operating lever for operating the rotor 3 to move forward with respect to the cover body 5, and 7 is a return spring.

The present invention is constructed as described above, and the depth reading device of the present invention is used, for example, when fishing on a boat with a fishing rod equipped with a fishing reel, and the mounting leg 1 is attached to the fishing rod or the fishing rod. The intermediate portion of the fishing line pulled out from the spool of the reel is wound once around the winding groove 32 of the rotor 3.

This fishing line moves in contact with the bottom surface of the bobbin groove 32, and the groove width H at the open end of the bobbin groove 32 is equal to the knot A in the fishing line.
Since the width is such that it is possible to prevent the intervention of the fishing line, even if there is a knot A in the middle of the fishing line, this knot A will come into contact with the open end 32a of the bobbin groove 32 and move.

Therefore, the entry side yarn B entering the bobbin groove 32
moves in contact with the bottom surface of the bobbin groove 32, therefore, the advancing position 01 of the knot A and the entering position 02 of the entering side yarn B are displaced in the radial direction of the rotor 3. There is. Therefore, when the knot A is caught on the entry side yarn B at a position slightly before the advance position 01 as shown in _FIG. radially outward of the rotor 3, specifically, to the moving position of the knot A, and the entering side thread B
Then, an inward return force acts on the knot A to return it to the bottom side of the bobbin groove 32, and this return force prevents the entry side thread B from getting caught in the knot A. It will come off. Therefore, even if there is a knot A in the middle of the fishing line and the knot A hooks on the entering line B, the fishing line can be pulled out without being doubled or tangled in the middle.

Note that the width of the fishing line wound around the bobbin groove 32 may vary depending on the way the fishing line is wound around the bobbin groove 32 or the positional deviation of the bobbin groove 32 relative to the fishing line guide on the fishing rod when pulled out. Since the fishing line may lean to one side in the direction, the bottom surface of the wide groove 33 prevents the fishing line following the knot A from being wound around the wide groove 33.
It is preferable to provide a guide portion 34 for guiding the object. A plurality of guide portions 34 may be provided at predetermined intervals in the circumferential direction of the wide groove 33, or one guide portion may be provided.

(Effect of the invention) As described above, the present invention provides the thread winding groove 32 for the fishing line on the outer peripheral surface of the rotor 3, and the winding groove 32 for the fishing line.
The groove width H at the open end of the fishing line is set as a width that can prevent the knot from intervening in the fishing line.
The entry position of the entry side thread entering the thread and the exit position of the knot moving along the bobbin winding groove 32 are determined by the rotor 3.
Since the fishing line can be displaced in the radial direction, there is a knot in the middle of the fishing line, and this knot
Even if it is caught with the entering side thread, the entering side thread is
The radially inward return force of the rotor 3 acts on the knot, thereby making it possible to release the entry-side yarn from the knot. Therefore, even if the fishing line has a knot in the middle, the fishing line can be pulled out without being doubled or tangled in the middle, and the depth can be accurately read.
