Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ruler and scale used by fishermen and the like to measure the size of fish caught and to compare the weight of fish.

[0002]

[Prior Art]

 Conventionally, when measuring the size of a fish caught by an angler or the like, one end of a flat plate of a predetermined length is bent at a substantially right angle, and a ruler plate with a scale on its inner side is used to bend the bent part. The measurement was performed by abutting the head of the fish on the head and reading the position of the tip of the tail on a scale.

[0003]

[Problems to be solved by the device]

 However, conventionally, when the lengths were almost the same and it was necessary to compare the sizes by weight, it was very troublesome to compare the weights on each scale.

Further, it is necessary to separately prepare a ruler and a scale, which is bulky, inconvenient to carry, and easy to lose.

The present invention is intended to solve the drawbacks of the above-mentioned conventional example, and a fisherman or the like can measure the size of the fish caught and compare the weights of the fish with one device. The purpose of the present invention is to provide a ruler / balance that has a simple structure and is very easy to operate.

[0006]

[Means for Solving the Problems]

 That is, the ruler / balancer of the present invention is such that one end of a flat plate portion of a predetermined length is bent at a substantially right angle, and a scale is formed on the inner side surface of the ruler plate, and hanging metal fittings are provided at substantially the center and both ends thereof. The feature is that it can be attached and used as a scale.

[0007]

[Action]

 Since the ruler / balance of the present invention is configured as described above, it is possible for an angler or the like to measure the size of the fish caught by the fisherman and compare the weights of the fish with one device.

Moreover, it is possible to provide a ruler / balance having a simple structure and excellent operability.

【Example】

 An embodiment of the ruler and balance of the present invention will be described below with reference to the drawings.

FIG. 1 to FIG. 3 show an embodiment of a measuring instrument and a balance according to the present invention.

In FIG. 1, reference numeral 1 denotes a ruler plate made of a metal such as aluminum or stainless steel, FRP or other hard material. The ruler plate 1 has a corner portion 3 formed by bending one end of a flat plate portion 2 having a predetermined length at a substantially right angle, and has a scale 4 on the inner side surface thereof.

The scale 4 is formed on the side surface of the ruler plate 1 by means such as printing or stamping, and can measure up to about 40 cm in FIG.

Small holes 5 are formed in the upper part of the center and lower parts of both ends of the rule plate 1, respectively, and a hanging metal fitting 7 is attached to the small holes 5 via a ring 6. As shown in FIG. 3, the hanging metal member 7 is formed by rolling a metal wire material having spring elasticity into an elliptical shape. Then, one end of the hanging metal fitting 7 is bent outward at a right angle at the folded back portion, and its tip is folded back inward to form a hook 8. Moreover, the other end has a predetermined length and spring elasticity, and is bent outward at a predetermined angle to form a locking portion 9. Therefore, the hook 7 can be easily hung by engaging the hook 8 with the hook 9 after passing the tip of the hook 9 through the mouth of the fish.

Therefore, if a fish is hung on the hanging metal fittings 7 on both sides of the ruler board 1 and lifted at the upper center part of the ruler board 1, it is possible to easily determine which of the fishes on both sides is heavier and also as a scale. Can be used.

2 and 3 show the actual operation of the ruler / balance of the present invention. The hanging metal fitting 7 is attached to the ring 6 of the ruler board 1 in advance. Then, the fish that has been caught is applied to the scale 4 of the ruler board 1 and the length is measured. In addition, the reference fish or the largest fish up to that point is hung on one of the hanging fittings 7, and the fish caught on the other hanging fitting 7 is hung, and the weights are compared. By doing this, not only the length of the fish but also the weight can be measured, and the fishing results can be easily compared.

[0016]

[Effect of the device]

 Since the ruler / balance of the present invention is configured as described above, it is possible for an angler or the like to measure the size of the fish caught by the fisherman and compare the weights of the fish with one device.

In addition, it is possible to provide a ruler / balance having a simple structure and excellent operability.

FIG. 2 is a perspective view showing a case where the length of a fish is measured.

FIG. 3 is a perspective view showing a state where weights are compared.
