  However, when the fish container is immersed in water, when the closed body receives a water flow, the closed body may open against the biasing force and the fish in the container may escape.

  In particular, tow boats are easily drawn by the water flow, so they can be swept by the water flow and turn over. When the tugboat is reversed, a stronger water pressure in the water is applied to the obstruction body, and the insertion port is opened widely, and the fish may easily escape from inside.

  The present invention has been devised in view of such circumstances, and an object of the present invention is to provide a fish container in which a closing body of a fish inlet is difficult to open by a water flow.

  In order to achieve such an object, the invention according to claim 1 is directed to a fish container in which a closing body urged in the closing direction from the inside is rotatably attached to a fish insertion port. A water flow hole is provided, and a resistance surface is provided for urging the closing body in the closing direction when a water flow flowing down the water passage hits.

  The invention according to claim 2 is the fish container according to claim 1, wherein one end of the closing body is pivotally attached to an arbitrary position of the fish container and the other end is a free end. In addition, the resistance surface is an inclined surface that descends to the other end side that is a free end of the closing body, and the invention according to claim 3 is the fish container according to claim 1 or 2. However, the resistance surface is provided on an inner peripheral surface of the water passage hole.

  The invention according to claim 4 is the fish container according to claim 1 or 2, characterized in that the resistance surface is provided on the free end side from the water passage hole, According to a fifth aspect of the present invention, in the fish container according to the second or fourth aspect, the resistance surface is provided at a peripheral portion of the closing body.

  Further, the invention according to claim 6 is the fish container according to claim 5, wherein the resistance surface is an inclined surface of a bent piece provided at a rear end side peripheral portion which is a free end of the closing body. It is characterized by being.

  According to the invention according to each claim, since the water passage holes are provided in the obstruction body, the water flow applied to the obstruction body flows down from the outside to the inside, and the obstruction body against the water flow. Pressure resistance is reduced.

  In this way, the water flow flows from the outside to the inside through the water passage hole and hits the resistance surface to urge the closing body obliquely upward, so that the force that closes the inlet acts on the closing body. Will be.

  Therefore, even if a strong water flow is applied to the obstruction body, the obstruction body is less likely to open due to the water flow than in the conventional case, so that the inlet is not inadvertently opened due to the water flow. It was possible to prevent the fish from escaping.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  1 to 3 show an embodiment in which the invention according to claims 1 to 3 is applied to a tow boat. In the figure, 1 is formed into a box-like boat shape using a hard synthetic resin material.

A fastening device (not shown) to a belt or the like is attached to the other end side of the traction rope 11.

  Also, a plurality of water inlets 13 for allowing water to flow into the container body 1 are formed on the side surface 3 slightly behind the through-hole 5, and when the container body 1 is drawn into the flow while being pulled by the tow rope 11. The tip floats upstream of the flow, and a drain port (not shown) is provided on the rear side of the container body 1 so that fresh water circulates inside the container body 1.

  As shown in FIG. 1, a fish outlet 17 is formed on the tip side of the upper surface 15 of the container body 1, and a front opening lid 19 that opens and closes the outlet 17 is attached via a hinge 21. In addition, an opening / closing operation portion 23 of the lid body 19 is attached to the front portion of the lid body 19, and the rear portion of the lid body 19 is attached to the container body 1 by the hinge 21.

  Note that the accessory of the container main body 1 such as the lid 19 is included in the container main body 1, and the lid 19 may not be provided on the upper surface 15 of the container main body 1 when the fish main body 1 is not provided.

  As shown in FIG. 2, the opening / closing operation portion 23 is formed of a locking piece having an L-shaped cross section, and the opening / closing operation portion 23 is inserted through the lid body 19, and one end 25 side thereof is provided on the upper portion of the lid body 19. A shaft 27 is pivotally mounted in the recess 27 so as to be pivotable in the front-rear direction via a pivot shaft 29.

  On the other hand, a locking portion 31 on the other end side of the opening / closing operation portion 23 formed at an acute angle is locked in a locking hole 33 provided on the inner surface of the container body 1, and the opening / closing operation portion 23 is a spring (not shown). The spring 31 is biased so that the locking portion 31 is always locked in the locking hole 33. Then, when one end 25 of the opening / closing operation portion 23 protruding into the recess 27 is operated forward (in the direction of arrow A in FIG. 2) against the spring force of the spring, the engagement is as shown by a two-dot chain line in FIG. The locking state between the stopper 31 and the locking hole 33 is released, the lid 19 is opened, and the outlet 17 is opened.

  As shown in FIGS. 1 and 2, the lid 19 of the container body 1 has a substantially elliptical insertion port 37 in plan view through which caught fish (fish) is introduced into a tow boat (fish container) 35. A closing body 39 urged in the closing direction from the inside is rotatably attached to the input port 37.

  The closing body 39 includes a pair of substantially semi-elliptical divided bodies 39a and 39b that are divided into left and right, and each of the divided bodies 39a and 39b has a front portion on one end side via a rotating shaft 41. The rear end of the charging port 37 is pivotally attached, and the rear end of the other end is a free end that opens and closes to the charging port 37. Both split bodies 39a and 39b are biased in the direction of closing the inlet 37 from the inside by the spring force of a coil spring (biasing body) 43 wound around the rotating shaft 41.

  Further, as shown in FIGS. 1 and 2, a convex portion 45 protruding upward is provided on the front side of the closing body 39 so as to extend over both the divided bodies 39a and 39b, and the coil spring 43 can be held with the hand holding the fish. When the convex portion 45 is pressed downward against the spring force of the spring, the split bodies 39a and 39b open downward as shown by the two-dot chain line in FIG. It can be thrown into.

  In addition to the configuration as described above, this embodiment reduces the pressure receiving resistance of the closing body 39 against the water flow W and prevents the closing body 39 from being opened by the water flow W, as shown in FIGS. In the closed body 39 (divided bodies 39a, 39b), a plurality of water passage holes 47 having a rectangular shape in plan view, a triangular shape in plan view, and the like are provided from the center of the closed body 39 to the rear side. A water flow W flowing down from the outside to the inside hits the inner peripheral surface of the hole 47, and the water flow W rotates around one end side of the closing body 39 around the rotation shaft 41. The other end side is biased upward (in the direction of arrow B in FIG. 3), and a resistance surface 49 is provided to close the inlet 37 with the closing body 39 by the force of the water flow W. Is provided at least on the free end side of the closing body 39 on the inner peripheral surface of the water passage hole 47 and is a free end of the closing body 39 Down to the rear side, i.e., it is formed as inclined surfaces descending from the upstream side of the water flow W to the downstream side.

  In addition, in FIG. 2, 51 is a buoyancy body embedded in the tip of the container body 1.

  Since the tow boat 35 according to the present embodiment is configured in this way, as in the conventional case, if the tow boat 35 is drawn in the flow, the water flow W is received, and the water flow W may be swung and inverted. At that time, a strong water flow W is applied to the closing body 39 (divided bodies 39a and 39b).

  However, since the closing body 39 is provided with a plurality of water passage holes 47, the water flow W applied to the closing body 39 flows down from the outside to the inside, and the closing body with respect to the water flow W. The pressure receiving resistance of 39 is reduced. In this way, when the water flow W flows down from the outside to the inside through each water hole 47, the water flow W hits the resistance surface 49 on the rear (free end) side of each water hole 47 and closes the blocking body 39. Is biased obliquely upward in the closing direction (in the direction of arrow B in FIG. 3), the force for closing the inlet 37 acts on the closing body 39.

  Therefore, according to the present embodiment, even when a strong water flow W is applied to the closing body 39, the closing body 39 is less likely to be opened by the water flow W as compared with the conventional case. As a result, it was possible to prevent the fish from escaping from the inside of the tow boat 35.

  FIG. 4 shows an embodiment in which the invention according to claims 1 to 4 is applied to a tow boat, and this embodiment is also pivotally attached to the insertion port 37 of the lid 19 in the same manner as the above embodiment. The closed body 39-1 is provided with a plurality of water holes 47-1 and the water flow W flowing down from the outside to the inside hits each water hole 47-1. Is formed as an inclined surface that descends from the upstream side to the downstream side of the water flow W. In order to increase the force for urging in the direction, the resistance surface 49-1 is located below the closing body 39-1 on the lower surface side (the inner surface side of the container body 1) of the closing body 39-1 and the rear portion of the water passage hole 47-1 It extends to the side (the free end side of the closing body 39-1).

  In addition, since the other structure is the same as that of the said embodiment, the same code | symbol is attached | subjected to the same thing and those description is abbreviate | omitted.

  Thus, according to the tow boat 35-1 according to the present embodiment, the resistance surface 49-1 is longer than the resistance surface 49 of FIG. 3 to the lower side and the rear (free end) side of the closing body 39-1. Therefore, the force for urging the closing body 39-1 in the closing direction is further increased, and the closing body 39-1 is more difficult to open by the water flow W.

  Therefore, according to the present embodiment, the introduction port 37 is further prevented from being inadvertently opened by the water flow W, and there is an advantage that the fish can be more reliably prevented from escaping from the inside of the tow boat 35-1.

  5 and 6 show an embodiment in which the invention according to claims 1, 2 and 4 to 6 is applied to a tow boat, in which 39-2 is the same as the closing body 39, As shown in FIG. 6, each of the divided bodies 39-2a, 39-2b is a front part of a closed body composed of a pair of substantially semi-elliptical divided bodies 39-2a, 39-2b divided into left and right. The part is attached to the rear surface side peripheral edge portion of the insertion port 37 via the rotation shaft 41. The split members 39-2a and 39-2b are biased in a direction to close the inlet 37 from the inside by the spring force of the coil spring (biasing member) 43 wound around the rotating shaft 41. Yes.

  As shown in FIG. 5, this embodiment also reduces the pressure receiving resistance of the closing body 39-2 against the water flow W, so that the rotation shaft 41 of the closing body 39-2 (divided bodies 39-2a, 39-2b). A plurality of water passage holes 53 extending radially from the front side pivotally attached to the rear side to the free side are provided radially, and further, the water passage holes 53 are formed in the peripheral portion of the closing body 39-2 from the outside to the inside. A resistance that causes the blocking body 39-2 to be blocked by the closing body 39-2 by the force of the water flow W by hitting the blocking body 39-2 obliquely upward (in the direction of arrow B in FIG. The resistance surface 55 is formed at the free end of the peripheral portion of the closing body 39-2 on the rear side of the water passage 53, and the lower surface side of the closing body 39-2 (the container body 1). Is formed with an inclined surface 59 that descends from the side on which the closed body 39-2 of the bent piece 57 projecting to the free end side to the free end side.

  Since other configurations are the same as those of the embodiment of FIG. 1, the same components are denoted by the same reference numerals and description thereof is omitted.

  Thus, the tow boat 35-2 according to this embodiment can achieve the intended purpose as in the above-described embodiments. Since the resistance surface 55 is provided at a position farther from the rotation shaft 41 than the form, a sufficient effect can be expected even if the resistance surface 55 is reduced.

  As shown in FIG. 7, in order to reduce the pressure receiving resistance of the blocking body 39-3 against the water flow W, the blocking body 39-3 (divided bodies 39-3a and 39-3b) has a rectangular shape in plan view. A plurality of water passage holes 47-3 having a shape, a triangular shape in plan view, and the like are provided from the center to the rear side of the closing body 39-3, and further, as shown in FIG. The water flow W that flows down the water passage holes 47-3 hits the inner peripheral surface from the outside to the inside, and the water flow W moves obliquely upward (in the direction of arrow B in FIG. 8) through the closing body 39-3. And a resistance surface 49-3 that closes the inlet 37 with the closing body 39-3 by the force of the water flow W is provided, and the resistance surface 49-3 is a rear portion that is a free end of the closing body 39-3. In other words, it is formed with an inclined surface that descends from the upstream side of the water flow W (the side that is attached to the rotating shaft 41 of the closing body 39-3) to the downstream side (the free end side of the closing body 39-3). Has been. Then, as in the embodiment of FIG. 4, in order to increase the force for urging the closing body 39-3 in the direction of arrow B, the resistance surface 49-3 is located below the closing body 39-3 and from the water passage hole 47-3. The structure extends to the free end side.

  In addition, the resistance surface 49-3 on the rear end side of the free end is a bent piece projecting to the lower surface side (the inner surface side of the container main body 61) of the closing body 39-3 provided on the peripheral edge of the rear end side.

  Since the decoy can 67 according to the present embodiment is configured as described above, when the decoy can 67 is put in water, the water flow W strong against the blocking body 39-3 (divided bodies 39-3a and 39-3b) is provided. Even when the closed body 39-3 is provided with a plurality of water holes 47-3, the water flow W applied to the closed body 39-3 flows from the outside to the inside. -3 flows down, and the pressure receiving resistance of the closing body 39-3 with respect to the water flow W is reduced. In this way, when the water flow W flows down from the outside to the inside through the water flow holes 47-3, the water flow W hits the resistance surface 49-3 of each water flow hole 47-3, and the closed body 39- 3 is biased obliquely upward in the closing direction (in the direction of arrow B in FIG. 8), a force for closing the charging port 37 acts on the closing body 39-3.

  Therefore, according to the present embodiment, even if a strong water flow W is applied to the closed body 39-3, the closed body 39-3 is difficult to open by the water flow W, so the inlet 37 is opened carelessly by the water flow W. As a result, there is an advantage that the fish can be prevented from escaping from the decoy can 67.
