Description

      The present invention relates to a fish body length measuring device used for measuring the total length of fish caught in, for example, a fishing competition.

      In fishing tournaments, it is common practice to report the results of fishing with the total length of the fish that have been caught, and the ranking is determined by the size.

Conventionally, various fish body length measuring devices used for measuring the total length of fish have been proposed (see, for example, Patent Document 1).
The fish body measurement measure shown in Patent Document 1 is provided with a reference wall that comes into contact with the mouth of the fish and measures the fish body length up to the tip of the tail fin, but the fish is open or closed, or If the body length is measured while the fish is moving and the mouth is open, the length of the fish is measured longer than when the fish is measured with the mouth closed. However, there is a problem that an error occurs in the measurement of the full length of the fish depending on the state of the mouth of the fish.

In addition, when the difference in total length of the fish is small, there is a problem that troubles such as quarrels between anglers occur due to errors caused by the measurement method.

      The present invention solves the above-described conventional problems, and provides a fish body length measuring device that does not cause errors in measurement even when the difference in the overall length of fish is small.

      In order to solve the above problems, a fish body length measuring device of the present invention includes a scaled fish mounting table, and a mouth closing tool for closing the fish mouth by contacting the fish mouth mounted on the scaled fish mounting table. It is characterized by having.

In order to solve the above problems, the fish body length measuring device of the present invention includes a scaled fish mounting table, a mouth plate provided on the scaled fish mounting table, and a fish mounted on the scaled fish mounting table. A mouth closing tool that closes the mouth of the fish by contacting the mouth, and the mouth closing tool is provided inside the mouth plate .

The fish body length measuring device of the present invention is a fish mounting table with scales , a mouth plate provided on the fish mounting table with scales , and a fish mouth mounted on the fish mounting table with scales. A mouth closing device for closing the mouth, and the mouth closing device is provided inside the mouth plate, so that the body length of the fish body can be measured with the fish mouth closed. It is possible to reduce the error caused by the angler's individual measurement method, and to be able to impart fairness and superiority.

FIG. 1 is a perspective view showing an embodiment of the present invention. FIG. 2 is a side view showing an embodiment of the present invention. FIG. 3 is a side view showing a state in which the embodiment of the present invention is folded and stored. FIG. 4 is a use state diagram showing the measurement of the fish body length according to the embodiment of the present invention. FIG. 5 is a perspective view and an enlarged view of a mouthpiece plate showing an embodiment of the present invention. FIG. 6 is a right side view showing an embodiment of the present invention.

One embodiment of the present invention is shown in FIGS. The fish body length measuring device 1 includes a scaled fish mounting table 2, a mouth plate 3 provided at one end of the scaled fish mounting table 2, and an inner surface of the mouth plate 3 in contact with the mouth of the fish. It is comprised with the mouth closing tool 4 which closes a mouth. The scaled fish mounting table 2 is divided into three, and the first scaled fish mounting table 2a, the second scaled fish mounting table 2b, and the third scaled fish mounting table 2c entered the first scale. The fish mounting table 2a, the second scaled fish mounting table 2b, and the third scaled fish mounting table 2c are connected to each other by hinges 5 so as to be foldable, and the first scaled fish mounting table. 2a, the second scaled fish mounting table 2b, and the third scaled fish mounting table 2c are configured not to be undulated by the hinge 5. The scaled fish mounting table 2 is made of aluminum. The scaled fish mounting table 2 is divided into three parts, but it is not limited to that and may be not divided into one piece, and is divided into a plurality of pieces such as two parts and four parts. It does not matter. A sticker 6 with a scale indicating the length is affixed to the first scaled fish mounting table 2a, the second scaled fish mounting table 2b, and the third scaled fish mounting table 2c. Although it plays the role of showing the total length at the time of measurement, the scale indicating the length directly on the first scale-containing fish mounting table 2a, the second scale-containing fish mounting table 2b, and the third scale-containing fish mounting table 2c by printing or the like The scale-mounted fish mounting table 2 is a part of the fishing equipment such as the upper surface of the cooler box lid, and the scale is displayed on the upper surface of the lid by printing or the like. It does not matter. Thus, the scaled fish mounting table 2 may not be plate-shaped.
Moreover, although the Example provided the mouth closing tool 4 which contact | abuts the fish's mouth and closed the fish's mouth on the inner surface of the mouthpiece plate 3, it was directly attached to the fish mounting table 2 with the scale. It does not matter.

The mouthpiece plate 3 has protrusions 7 formed at both ends of the mouthpiece plate 3, and stands up at an angle of 90 degrees with respect to the first scaled fish mounting table 2 a and is provided with a thumbscrew 8 so as to fall down. Is attached to the standing walls 9 provided at both ends in the short direction of the first scale fish mounting table 2a so as to be freely rotatable, and the first scale fish mounting table 2a in a state where the mouth plate 3 is tilted down. By being positioned above, the first scale fish mounting table 2a, the second scale fish mounting table 2b, and the third scale fish mounting table 2c are prevented from spreading. The mouthpiece plate 3 is made of aluminum.

      The mouth closure 4 is a member that forcibly closes the mouth of the fish when measuring the total length of the fish, is formed of a brass plate having a thickness of 0.5 mm, and is folded into a U-shaped cross-section. The width of the opening is about 2 centimeters, and the width of the attachment to the mouthpiece plate 3 is 1.6 centimeters. A brass plate with a thickness of 0.5 mm can be deformed, the width can be made variable according to the size of the fish, and the width can be adjusted according to the size of the fish It becomes. The end of the mouth closing device 4 is doubled by being bent outward, thereby preventing the mouth of the fish from being damaged by the mouth closing device 4. The material and the plate thickness may be metal plates or plastics of other materials as long as plastic deformation is possible to some extent. The size of the mouth closure 4 may be set as appropriate depending on the size of the fish to be measured. If a plurality of different sizes are prepared, a material that does not undergo plastic deformation may be used. There is nothing. The mouth closing device 4 is detachably attached to two longitudinal grooves 10 formed in the mouthpiece plate 3. The closing device 4 is detachably attached to the two vertical grooves 10 formed on the mouthpiece plate 3. However, if the attachment device does not protrude at the position where the fish mouth of the mouth closing device 4 abuts, It does not matter.

  Next, the usage method of the fish body length measuring apparatus 1 of the present invention will be described. As shown in FIG. 4, the total length of the fish is measured. When measuring the full length of the fish body, the first scaled fish mounting table 2a and the mouthpiece plate 3 can be set up at right angles with the thumbscrew 8 as a base point. The inner surface of the mouth closing tool 4 that hits the mouth of the fish on the surface is the measurement standard. Since the mouth closing device 4 is formed in a U-shaped cross section, the position of the fish mouth on the eye side first contacts the opening of the mouth closing device 4 to close the fish mouth. When the mouth of the fish is closed by using the behavior that keeps the mouth closed physically, the fish does not try to open the mouth but remains closed. It can be done easily, and it can be easily made into an evidence photo.

  According to this embodiment, when folded as shown in FIG. 3, portability can be greatly improved.
