Description

[Detailed description of the invention] This invention relates to a bamboo sink tube that is used for fishing with sweetfish, etc., and is tied to the waist with a string and moved through the water.

Traditionally, there was a sink tube for tomo fishing that was simply cut out of large bamboo and used as a cylinder, but since bamboo has a roughly circular cross-section,
They lacked stability in the water and were thrown around by water currents while moving, causing the strings to twist and the sweetfish kept in the case to lose their vitality.

This idea was devised to solve these problems with conventional sink tubes, and will be explained below using the example shown in the drawings. Divided walls 1 and 1' are made, separated by a predetermined distance, and the lower surface of the divided space is covered with an elongated bamboo board 3, and the upper surface is covered with an elongated bamboo board 4 in the rear half, and approximately the rear half is made of bamboo skin. Long and narrow bamboo plates 5 formed only on the portion 5a to maintain elasticity are hermetically joined via bamboo nails 6 to form a cylinder main body A having a flat elliptical shape from the front and an emergency inlet B formed on the top surface. do.

A bottom wall 7 is airtightly fixed to the rear opening with bamboo nails 8, and a lid wall 9 with a water passage hole 10 is attached to the front opening so that it can be opened and closed with respect to the cylinder body A using a pivot pin 11. .

Reference numeral 12 and 13 in the drawing indicate a hole through which a tow string is passed, and in actual use, as shown in FIG. 3, the tow string 14 is passed through and the tip is tied to the waist, and the object is dragged through the water.

This sink tube is as described above, and since the tube body A has a flat oval shape, it is stable in the water, and even if it is turned by strong waves, it will return to its original position immediately, so the fish inside will be useless. It can maintain vitality without being forced to exercise, and has a larger swimming volume than a cylinder.

Furthermore, when towed underwater by a tow string, a flat elliptical cylinder receives buoyancy more effectively than a cylinder, so that so-called sagging can be prevented.

From the above, this project takes advantage of the advantages of bamboo tubes, which are ideal as a material for sink tubes, such as their specific gravity and water resistance, while overcoming the drawbacks of bamboo tubes being cylindrical in nature. Since it is provided on the upper surface, that is, on the horizontal surface, it has the advantage that fish can be put in easily, and is truly useful.
