[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in a yarn length measuring device for fishing reels.

[0002]

[Prior art]

 The applicant previously disclosed in Japanese Patent Laid-Open No. 5-23083 a fishing reel line length measuring device capable of measuring the amount of fishing line delivered and the amount of reeled fishing line.

This yarn length measuring device includes a sensor for detecting the rotation of a spool rotatably supported by a reel unit, an up / down counter for up / down counting a pulse signal output from the sensor, A bobbin diameter measuring means for measuring the bobbin diameter by emitting an ultrasonic beam from an ultrasonic sensor to the bobbin diameter surface of the spool, the bobbin diameter data from the bobbin diameter measuring means and the count value of the up / down counter. A reel body having a sensor support for detachably mounting an ultrasonic sensor, which is equipped with a computing means for computing the yarn length based on the base and an indicator for displaying the yarn length computed by the computing means. Is.

FIGS. 8 and 9 show a mounting structure of a sensor support in the above yarn length measuring device. In this conventional example, a notch 7 is formed at the center of the lower part of the column 5 of the reel body 3 behind the spool 1. Then, the sensor support 9 is removably mounted in the notch 7 through the screw 11, and the sensor mounting hole 13 provided in the spool facing surface 9a of the sensor support 9 is superposed. The sound wave sensors 15 and 17 are mounted so as to face the spool 1, and an ultrasonic wave beam is emitted from the ultrasonic wave sensor 15 to the bobbin diameter surface 19 and the reflected wave is received by the ultrasonic wave sensor 17. ing.

According to the yarn length measuring device, when the ultrasonic sensor 15 emits an ultrasonic beam to the bobbin diameter surface 19 of the spool 1, the reflected wave is received by the ultrasonic sensor 17. The time until it is measured is measured by a time measuring means.

Then, the time measured by the time measuring means is converted into an electric signal proportional to the diameter of the bobbin, and the rotation of the bobbin diameter signal and the rotation corresponding to the number of rotations at the time of winding or winding the thread counted by the up / down counter. Based on the number, the line length of the fishing line 21 is calculated by the calculating means, and the numerical value is displayed on the display unit 23 as the payout line length.

[0007]

[Problems to be solved by the device]

 As described above, the yarn length measuring device emits an ultrasonic beam from the ultrasonic sensor 15 to the bobbin diameter surface 19 of the spool 1, and the reflected wave is received by the ultrasonic sensor 17 and is wound by the time measuring means. Since the yarn length is calculated based on the spool rotation speed after measuring the diameter, according to such a yarn length measuring apparatus, the feeding amount and the winding amount of the fishing line 21 can be increased from the rotation speed of the spool 1. It can measure with high accuracy, and since the yarn length measuring device is small and lightweight, it can be applied to fishing reels of various sizes regardless of the yarn type.

By the way, in actual fishing, a fisherman often hits a fishing reel on a boat rim or a cooler box or accidentally drops it on the ground. However, the ultrasonic sensors 15 and 17 are extremely difficult. The delicate structure may cause an abnormality when the sensor support 9 receives an impact from the outside.

However, in the fishing reel described above, since no countermeasure against external impact is applied to the sensor support body 9, when the external force is directly applied to the sensor support body 9, ultrasonic waves are generated. There is a risk that the performance of the sensors 15 and 17 will be affected and that the yarn length measurement will not be possible or the measurement accuracy will be reduced.

Further, when the tackle is wound up in actual fishing, a fishing line 21 containing a large amount of seawater is wound around the spool 1. Therefore, as the tackle is wound up, as shown in FIG. Seawater W scatters.

Although dust and foreign matter are mixed in the seawater W, conventionally, as shown in FIGS. 8 and 9, in this type of yarn length measuring device, no measures are taken against the scattered seawater W. Therefore, the seawater W scattered at the time of winding may adhere to the surfaces of the ultrasonic sensors 15 and 17 and affect the performance of the ultrasonic sensors 15 and 17.

Of course, in the mounting structure shown in FIG. 8, when seawater W adheres to the surfaces of the ultrasonic sensors 15 and 17, the screws 11 are removed and the sensor support 9 is removed from the support column 5 to attach the seawater W. It was possible to remove the seawater W, but it was difficult to remove the screw 11 at the actual fishing spot.

The present invention has been devised in view of the above circumstances, and protects an ultrasonic sensor that emits an ultrasonic beam to the bobbin diameter surface of a spool from an external impact, and also winds the spool when the device is wound. An object of the present invention is to provide a yarn length measuring device for a fishing reel, which protects the ultrasonic sensor from seawater scattered backward.

[0014]

[Means for Solving the Problems]

 In order to achieve such an object, the invention according to claim 1 is a sensor for detecting the rotation of a spool rotatably supported by a reel body, and an up / down counting for a pulse signal output from the sensor. / A down counter, a bobbin diameter measuring means for measuring the bobbin diameter by emitting an ultrasonic beam from an ultrasonic sensor on the bobbin diameter surface of the spool, and the bobbin diameter data from the bobbin diameter measuring means and the above-mentioned up / The ultrasonic sensor is attached to the sensor support attached to the reel unit, which comprises a calculating means for calculating the yarn length based on the count value of the down counter and an indicator for displaying the yarn length calculated by the calculating means. In a yarn length measuring device for a fishing reel, which is mounted so as to face the spool, the sensor support is attached to the lower side of the support column of the reel unit located behind the spool. Is attached by opening a gap, a protective cover for covering the outer periphery of the sensor support, characterized in that attached to the reel body to open the gap between the sensor support.

According to a second aspect of the present invention, in the yarn length measuring device for a fishing reel according to the first aspect, deformation of an end portion of the protective cover is prevented between the reel body and the protective cover. According to a third aspect of the present invention, in the yarn length measuring device for a fishing reel according to the first or second aspect, the surface of the ultrasonic sensor is a strut. It is characterized in that it is placed rearward from the end on the spool side.

[0016]

[Action]

 According to the invention of claim 1, as in the conventional fishing line length measuring device, when the fishing line is paid out from the spool in actual fishing, the amount of payout is measured and the length of the fishing line paid out is displayed on the display. When the fishing line is wound on the spool by winding up the device, the line length obtained by subtracting the take-up line length from the pay-out line length is calculated and displayed on the display unit. The protective cover protects the sensor support even if it hits the cooler box or drops it on the ground.Because there is a gap between the protective cover and the support and the sensor support, the protective cover and support will not be caught. The impact is not transmitted to the sensor support.

According to the second aspect of the present invention, when the reel unit is hit against a ship's edge, a cooler box, or the like, or is dropped on the ground, the deformation prevention unit prevents the end of the protective cover from being deformed. The cover reliably protects the sensor support.

Further, when the tackle is wound up, seawater is scattered from the fishing line to the rear of the spool. According to the invention of claim 3, the propeller blocks the scattered seawater and adheres the seawater to the ultrasonic sensor surface. Prevent.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Since the structure of the yarn length measuring device and the yarn length measuring operation excluding the devised portion are the same as those of the conventional example shown in FIGS. 8 and 9, description thereof will be omitted here, and the devised portion will be explained exclusively. . Then, the same components as those in the conventional example are indicated by the same reference numerals.

FIG. 1 is a partially cutaway plan view of a first embodiment of a fishing reel equipped with a yarn length measuring device according to claims 1 to 3, and FIG. 2 is a sectional view of the fishing reel. In the figure, reference numeral 25 is a column of the reel main body 27 located at the rear of the spool 1, and the column 25 is installed between the left and right inner plates 29 and 31 facing each other with a predetermined gap. It is supposed to function as. In order to improve the feel of the fingertip, as shown in FIG. 2, the upper side of the reel is rounded, and the lower side is flat so that the rear end of the reel body 27 projects rearward. ing.

A sensor support 33 is attached to the lower side of the support column 25 with a space provided between the sensor support 33 and the support 25, and is provided on the spool facing surface 35 of the sensor support 33 as shown in FIG. The ultrasonic sensors 15 and 17 are mounted in the two sensor mounting holes 37 so as to face the bobbin diameter surface 19 of the spool 1, respectively.

The sensor support 33 is composed of a pair of upper and lower split sensor supports 33a and 33b as shown in FIG. 3, and a V-shaped sensor opening surface 35a is formed at the center of the spool facing surface 35 facing the spool 1. Are formed. Then, the two divided sensor support bodies 33a and 33b are joined from above and below and fixed by screws 39, so that two sensor mounting holes 37 are opened in the sensor opening surface 35a, and each of the sensor mounting holes 37 is superposed. If the ultrasonic sensors 15 and 17 are attached, the ultrasonic sensors 15 and 17 are arranged in a V shape, and the ultrasonic sensor 17 can satisfactorily receive the reflected wave of the ultrasonic beam emitted from the ultrasonic sensor 15. It is like this.

The attachment of the sensor support 33 is as shown in FIG. 1 with the attachment pieces 41 attached to both sides of the divided sensor support 33a with a gap between the sensor support 33 and the lower side of the column 25. This is done by fixing it to the inner side plates 29, 31 with screws 43. Further, as shown in FIG. 2, when the sensor support 33 is attached to the lower part of the support column 25, the sensor support 33 is tilted upward so that the ultrasonic sensors 15 and 17 face the axis of the spool shaft 45 of the spool 1. As described above, the attachment piece 41 is attached to the sensor support 33 at a predetermined angle.

Furthermore, in this embodiment, when the sensor support 33 is mounted on the lower side of the support column 25, the spool facing surface 35 of the sensor support 33 is arranged rearward of the spool-side tip portion 25a of the support column 25. Thus, by displacing the spool facing surface 35 rearward from the spool-side tip portion 25a of the support column 25, when the tackle is wound up, the fishing line 21 is moved backward from the spool 1 as shown in FIG. The scattered seawater W is blocked by the pillars 25 so that the seawater W does not reach the sensor opening surface 35a.

Since the ultrasonic sensors 15 and 17 are arranged very close to each other, as shown in FIG. 3, a resonance member 47 made of urethane foam for preventing resonance between the ultrasonic sensors 15 and 17 is provided on the outer circumference thereof. Then, a shield material 49 made of a flexible substrate is wound around the ultrasonic sensors 15 and 17 to prevent mutual noise and maintain the original performance of the sensor. When the ultrasonic sensors 15 and 17 are mounted in the sensor mounting hole 37, the surfaces 15a and 17a of the ultrasonic sensors 15 and 17 are flush with the sensor opening surface 35a.

Therefore, as described above, when the device is wound up, the seawater W scattered behind the spool 1 is not blocked by the support column 25 and impinges on the sensor opening surface 35a. Seawater W does not splash on 15a and 17a.

A protective cover 51 is screwed to the reel body 27 so as to cover the outer periphery of the sensor support 33.

The protective cover 51 protects the sensor support 33 from falling of the fishing reel and external force, and is formed into a substantially L-shaped cross section as shown in FIG. It is screwed to the mounting portions 53 of the inner plates 29 and 31 with a gap between the outer periphery of the inner plates 29 and 31.

As shown by the broken line in FIG. 1, the center of the spool-side tip 51a of the protective cover 51 is formed in a V shape along the sensor opening surface 35a. The sensor opening surface 35a slightly projects to the spool 1 side. By thus projecting the sensor opening surface 35a to the spool 1 side, when the surfaces 15a and 17a of the ultrasonic sensors 15 and 17 become dirty, a protective cover is provided. The surfaces 15a and 17a can be cleaned with a cotton swab or the like without removing 51.

Further, as shown in FIGS. 2 and 4, a deformation preventing portion 55 including protrusions 55 a and 55 b that come into contact with each other is provided at the lower rear end of the column 25 and the upper edge portion of the protective cover 51. When the reel body 27 is accidentally dropped and an external force is applied to the protective cover 51, the protrusions 55a and 55b come into contact with each other to prevent deformation of the end portion of the protective cover. ing.

The sensor support 33 and the protective cover 51 that covers the sensor support 33 are thus attached to the reel body 27. In addition, as described above, the structure of the yarn length measuring device and its measuring operation are described in JP-A-5-23083. The description thereof is omitted because it is similar to the yarn length measuring device of No.

Since the present embodiment is configured in this way, when the fishing line 21 is paid out from the spool 1 in actual fishing, the amount of payout of the fishing line 21 is measured by a line length measuring device as in the conventional case. The length of the delivered yarn is digitally displayed on the display 23.

Then, when the fishing line 21 is wound around the spool 1 by the winding of the tackle, the line length obtained by subtracting the take-up line length from the delivered line length is calculated and displayed digitally on the display 23. At this time, seawater W is scattered from the fishing line 21 to the rear of the spool 1 as shown in FIG.

However, since the spool-side tip 25a of the column 25 projects toward the spool 1, the column 25 blocks seawater W that is about to be scattered on the surfaces 15a and 17a of the ultrasonic sensors 15 and 17, and the ultrasonic sensor It prevents the seawater W from adhering to the surfaces 15a, 17a of the parts 15, 17.

Even if the surfaces 15a and 17a of the ultrasonic sensors 15 and 17 are contaminated with the seawater W, the surfaces 15a and 17a may be cleaned with a cotton swab or the like without removing the protective cover 51 as described above.

Even if the reel body 27 is accidentally struck by a ship berth, a cooler box or the like or dropped on the ground, the protective cover 51 protects the sensor support 33, and the protective cover 51 and the support column 25 and the sensor 25 are protected. Since there is a gap with the support body 33, the impact applied to the protective cover 51 and the column 25 will not be transmitted to the sensor support body 33, and the protrusions 55a and 55b will abut each other and the end portions of the protective cover will be in contact with each other. Prevent deformation of the.

As described above, according to this embodiment, the external force is not directly applied to the sensor support body 33, and the seawater W is not attached to the surfaces 15a and 17a of the ultrasonic sensors 15 and 17 at all. Even if seawater W adheres, the surfaces 15a and 17a can be easily cleaned with a cotton swab or the like without removing the protective cover 51. Furthermore, the ultrasonic sensors 15 and 17 are provided on the outer circumference thereof. Since the resonance member 47 and the shield material 49 that prevent resonance and noise are wound, the performance of the ultrasonic sensors 15 and 17 can be maintained with higher accuracy than in the conventional case, and the yarn length measurement can always be performed well. became.

In the above embodiment, the projections 55a and 55b are integrally provided on the lower rear end of the column 25 and the upper edge of the protective cover 51 to form the deformation preventing portion 55. As described above, the engaging portions 59 and 61 are provided so as to project from the center of the lower surface and the rear end of the supporting column 57 that is formed in substantially the same shape as that of the supporting column 25. The deformation preventing portion 65 contacting the edge portion may be attached as a separate body, or, as shown in FIG. 6, the deformation preventing portion 71 including a step portion 70 with which the column 69 engages with the upper edge portion of the protective cover 67. May be provided to prevent deformation of the end of the protective cover.

Further, as shown in FIG. 7, a bending piece 75 that abuts from the rear end of the column 73 along the upper surface thereof is provided at the upper edge of the protective cover 77 to form the deformation preventing section 79. Good. Since the other constructions in each of these embodiments are the same as those of the embodiment shown in FIG. 1, the same components are designated by the same reference numerals and the description thereof will be omitted.

Thus, each of these embodiments can achieve the intended purpose as in the embodiment shown in FIG.

Further, in each of the above-described embodiments, the present invention is applied to a yarn length measuring device using two ultrasonic sensors 15 and 17. Needless to say, the present invention can be applied to the yarn length measuring device using one ultrasonic sensor disclosed in No. 223614.

[0042]

[Effect of device]

 As described above, according to the yarn length measuring device for a fishing reel according to the first aspect, even if the reel body is accidentally struck by a boat edge, a cooler box, or dropped on the ground, the protective cover is provided. Since the sensor support is protected and there is a gap between the protective cover and the sensor support, such external force is not directly applied to the sensor support, and as a result, the performance of the ultrasonic sensor is improved. It has become possible to maintain high accuracy and perform good measurement of fishing line length.

According to the second aspect of the present invention, since the deformation prevention portion prevents the end portion of the protective cover from being deformed, the protective cover can protect the sensor support more reliably. According to the yarn length measuring device for a fishing reel according to Item 3, in addition to the effects described above, it is possible to prevent seawater from adhering to the surface of the ultrasonic sensor, so that the performance of the ultrasonic sensor can be maintained with high accuracy. This has the advantage that the yarn length can be measured satisfactorily.
