Description

[Detailed explanation of the invention] (a) Purpose of the invention <Field of industrial application> This invention relates to a weighing scale for fishing fish that is used and carried during fishing competitions and the like.

<Prior Art> There are many cases where it is desired to measure the size or weight of a fish caught on the spot. Particularly when you want to know with certainty whether you have broken a previous record or your performance in a competition, it is easier to rely on visual measurements based on experience or the feel of it when you hold it in your hand. You'll probably get more reliable results if you use it.

However, it is difficult to weigh a fish that has just been caught because it jumps around so vigorously that it is difficult to weigh it on a scale. It takes a lot of effort to multiply the weight by the weight of the tare bag and then subtract the weight of the tare bag from the measured value, so things often don't work out quickly.

In addition, conventionally, many scales are made of metal, but when fishing in the sea, the sea breeze and salt water inevitably heat up the scales, so it is necessary to take care of the scales afterward. Rust may occur, resulting in shorter service life and inaccurate characteristic values.

<Problems to be solved by the invention> Therefore, the invention aims to catch fish without removing the fish from the hook or damaging the fish body.
In order to be able to weigh immediately on the spot, and to be able to quickly and easily attach and detach the scale, we have formed a hook on the scale in advance (the part that hooks the object to be measured), and if necessary, the scale is made of plastic. To provide a one-touch type fishing and fishing scale which does not have the risk of rusting or deterioration of its characteristics even if it is operated with fingers covered with tide water and left as it is.

(b) Structure of the invention <Means for solving the problems> In order to achieve the above object, the invention includes the following constituent elements.

(1) A spring-type hanging part for hanging the measured object is formed into a cylindrical body whose axis extends in the hanging direction, and a cylindrical body whose axis is perpendicular to the axis at a distance from the lower end surface of the cylinder. A notch extending from the peripheral wall to at least the axis is formed, and a V-shaped groove is cut into the cylindrical portion sandwiched between the notch and the lower end surface of the cylinder, parallel to the axis and whose apex coincides with the axis. A one-touch type fish scale that is characterized by:

(2) The one-touch type described in item (1) above, consisting of a spring-type suspension scale consisting of a helical coil spring made of carbon fiber molded with a synthetic resin agent and a graduated synthetic resin cylindrical body covering the spring. Fish scale.

<Function> A caught fish is hung down by pinching the fishing line close to the fish, and this is wrapped once or multiple times around the orthogonal notch of the locking cylinder as shown in Fig. 2, and then
Suspend the fishing line along the V-shaped groove, or fit the line along the V-shaped groove formed in the cylindrical locking part of the scale from the bottom end, and place the hand side into the locking part. It is bent at right angles to match the orthogonal notches provided and wrapped around the axis one or more times. At that time, the fishing line may be wound to the right or to the left. After that, if you lift the spring only,
The fishing line stuck in the V-shaped groove is pulled downward by the weight of the fish and moves to the top side of the V-shaped groove, aligning with the center axis of the spring and applying tension to the fishing line wrapped once or multiple times. The fishing line and the locking portion are substantially fixed together due to the frictional force of the line.

With the above process, you can easily catch the fish you caught.
When weighing the fish on a scale, the center of gravity of the fish coincides with the axis of the scale, allowing accurate weight measurement.

In addition, by unwinding the fishing line wrapped around the locking part from the notch, the fishing line and the object locking part can be easily separated from each other, making it possible to attach and detach the fish to and from the scale with a single touch. .

At this time, even if you operate the scale with hands that are wet with salt water, or if the scale is exposed to the sea breeze or has been hit by waves, the scale is made of plastic, so if you neglect post-treatment, it will rust. There is no risk of it coming out.

<Example> FIG. 1 is a diagram showing the main parts of a spring balance to be measured, in which a is a side view and b is a sectional view taken along line B-B in FIG. a. In the figure, 1 is a cylindrical hook, 2 is a notch that is perpendicular to the axis of the cylinder and reaches from the peripheral wall of the cylinder to at least the axis, and the notch 2 is provided at a slight distance from the end of the cylinder. It is sufficient that the cutout portion 2 is such that the hooking portion main body and the cylindrical body end portion 3 are not separated from each other, and that the notch portion 2 is sufficient to connect the two to suspend the weight of the fish.

4 is a V-shaped groove provided at the end 3 of the cylindrical body, which is cut deep from the peripheral wall in the axial direction and parallel to the axial center;
At this time, the line connecting the vertices of the grooves is aligned with the axis of the cylindrical body. Therefore, the groove 4 has a wide width on the peripheral wall of the cylindrical body and becomes narrower as it approaches the axis, and when the apex of the groove 4 coincides with the center of the cylindrical body and the fishing line is stored in the bottom of the groove from the outer periphery of the cylinder, When a tensile force is applied to the fishing line, you can easily
The fishing line is easily set in the bottom of the groove, where it coincides with the central axis of the catch cylinder.

The entire locking portion is integrally molded from engineering plastic to prevent damage to the fishing line and to provide good corrosion resistance.

The spring-type suspension balance may be of a commonly used type, as shown in cross-section in FIG. 3, and preferably has a capacity capable of measuring weights of about 1 kg or 10 kg.

The weighing spring is made of carbon fiber molded into a helical coil using epoxy resin, etc. The outside is covered, and the cylindrical member with scales, the lid member, and the hanging handle are also made of engineering plastic, making it slightly rough. The product should be made so that it will not be damaged or its properties will change even if it is used in different environments, and that it will not rust even if it is handled with hands that are wet with water or salt water.

In short, the above-mentioned object-to-be-measured hook is connected to the lower end of the weighing spring of the spring-type hanging scale as a substitute for the hanging hook provided at the lower end of the spring. The method of use and function of this embodiment of the scale are the same as described in the <Operation> section above, so they will not be explained again.

(c) Effects of the invention As described above, when using the present invention, the fish can be hooked and unhooked with a single touch without removing the fish from the hook or damaging the fish, so it can be easily hooked and unhooked on the spot. In addition to being able to easily and accurately weigh the fish you catch, the spring-loaded hanging scale used here
All of them are molded from synthetic resin, so
Even if it is used for a long time in an environment where salt water or the like is present, there is no risk of rust forming or changes in spring characteristics resulting in inaccurate measurements.
