Description

The present invention relates to an octopus box mainly used for bottom longline fishing such as large-sized species of octopus or medium-sized species of octopus.

As shown in FIG. 5, the mechanism of octopus bottom longline fishing (octopus box fishing) using an octopus box is to install a flag buoy 51, 51 as a mark on both ends and insert it into the longline trunk rope 52. , Sago 53 and 53 are attached as weights for moving the rope 52 to the sea floor, and 40 to 50 or more branch ropes 54, 54... Are connected at intervals of about 10 m. In general, an octopus box 55 having a size of about W300 to 350 mm × H190 to 230 mm × D400 to 500 mm is attached to the tip of the rope 54.

There are two types of octopus boxes: a wooden one that is assembled into a wooden box by joining wooden boards with nails and screws, a rubber one that is integrally molded with hard rubber, and a plastic one. The octopus box (wooden box) has the advantages of easy removal and handling of seawater, but it has the disadvantages that it is fragile and lacks durability when used in areas with high tidal currents and undulations on the seabed. The octopus box made of rubber is extremely heavy, so it has a heavy labor burden on the operator who performs the longline fishing for the bottom longline fishing into the sea and the hoisting work for collecting the input Because of the disadvantages such as a large load on the longline winder that winds up the mechanism from the seabed at a depth of 100 to 200 m, light and hard-to-break plastic octopus boxes are currently the mainstream.

As the plastic octopus box, for example, as shown in FIG. 6 (a), a type in which the entire box is integrally molded (Patent Document 1), or as shown in FIG. 6 (b), the upper half 61a of the box. And the lower half 61b are separately molded and both are assembled by joining them with bolts and nuts (Patent Documents 2 and 3), but the former is bulky and has a large space for storing it. Is necessary, and storage costs such as warehouse costs increase, and at the same time, there is a disadvantage that transportation efficiency is poor and transportation cost is remarkably increased. On the other hand, the latter can be stored and transported in a state where the octopus box is divided into the upper half 61a and the lower half 61b, but the shape of the upper half 61a and the lower half 61b, which are the halved portions. Since it has a concave bottom container shape with a low bulk reduction effect, storage cost and transportation cost cannot be significantly reduced, and the upper half body 61a and the lower half body 61b are joined with bolts and nuts. Since the flange portions 62a and 62b provided for this purpose protrude along the outer peripheral surface of the octopus box, there is a disadvantage that the resistance of the tidal current and water pressure is large and the load of the longline winder increases.

Due to the above circumstances, recently, there is a type of octopus box that assembles plastic plates with nails and screws and assembles them into a box just like a wooden octopus box that joins wooden plates with nails and screws. It is rapidly spreading.

This type of octopus box consists of a box front plate provided with an octopus inlet, a box rear plate provided with a rope hole for attachment to a branch rope of a long line, and a box body plate forming a rectangular tube box body Are individually molded from plastic, so these plates are stored in a stacked state, transported to the consumption area, and assembled into a finished product at the consumption area, greatly reducing storage and transportation costs. At the same time, the molding cost of each plate is significantly reduced compared to the cost of molding the upper half 61a and the lower half 61b of the concave bottom container shape as shown in FIG. An advantage is that it can provide a plastic octopus box.

However, the work of assembling the finished product by joining the box front plate, the box rear plate and the box body plate, which are constituent members of the octopus box, with a nail or a screw requires considerable skill, and is performed by an unskilled person. The work efficiency is remarkably bad, and when nails and screws are driven into the ends of the plates to be joined, the plates move unintentionally and are assembled into a distorted box shape. In many cases, an assembly failure occurs such that a screw is broken and a part or all of the nail or screw protrudes from the plate thickness. In particular, when assembling a rectangular tube-shaped box body by joining the ends of the box body plate with nails and screws, the box body plate is displaced and frequently causes damage to the nail and screw.

If an octopus box with a fragile joint due to a broken nail or screw is used, the fragile joint will be destroyed by the weight of the octopus and seawater in the octopus during the hoisting. The entire box may collapse. In particular, the world's largest species, Mizudako, is an adult of normal size and weighs about 10-15 kg. Therefore, there is a high risk that an octopus box used for bottom longline fishing of Mizudako will collapse due to damage of nails and screws.

The above is the structure of the octopus box according to the embodiment of the present invention. Next, the procedure for assembling the octopus box will be described. First, fitting convex portions 11, 11... Formed of chevron-shaped ridges formed on the joining side end portion 8 of one L-shaped angle plate 7 shown in FIG. 1 and the joining side end of the other L-shaped angle plate 7. The fitting recesses 12, 12... Formed of V-shaped grooves formed in the portion 9 are fitted together, and both the L-shaped angle plates 7, 7 are combined. As a result, as shown in FIGS. 3 and 4, the rectangular barrel body 6 is assembled by the L-shaped angle plates 7 and 7, and the box front plate 1 and the box are formed at the opening end of the box body 6. The rear plate 3 is fitted.

Next, in FIGS. 3 and 4, nails / screws prepared in the horizontal plate portion 6 a of the L-shaped angle plate 7 that forms the upper surface of the box body portion 6, F, F... And G, G. Screws 10, 10... For joining the plate portion 6 a to the vertical plate portion 6 b of the other L-shaped angle plate 7, the box front plate 1 and the box rear plate 3, and then the box body portion 6 is turned upside down. Are formed in the lower holes F, F..., G, G... Of the nail and screw formed in the horizontal plate portion 6a of the L-shaped angle plate 7 and the vertical plate of the other L-shaped angle plate 7. Screws 10, 10... To be joined to the portion 6 b, the box front plate 1 and the box rear plate 3, and then the pilot holes G of nails and screws formed in the vertical plate portions 6 b of both L-shaped angle plates 7, 7. , G... Are driven with screws 10, 10... For joining the vertical plate portion 6b to the box front plate 1 and the box rear plate 3 to complete the assembly operation of the octopus box.

Further, the box front plate 1 and the box rear plate 3 are fitted to the opening end of the box body 6 assembled by combining the L-shaped angle plates 7 and 7, and the end face is held at the same time as the back face. Since the side is locked to the positioning projection 13, when the screws 10, 10... For joining them to the L-shaped angle plates 7, 7 are driven, they are prevented from shifting or tilting.

Therefore, the work efficiency of the assembling operation of the octopus box is remarkably improved, and at the same time, the occurrence rate of the assembly failure due to the broken nail or screw is remarkably reduced, and the reliability of the octopus box is greatly improved. Also,
Since the components of the octopus box are a flat plate and an L-shaped angle plate, there is an advantage that the molding cost is not high and the storage and transportation costs are not high because they can be stored and transported closely stacked. .

In addition, when the octopus box is lifted from the sea, when the seawater accumulated in the box is discharged from the inlet 2 at the moment when the octopus inlet 2 provided on the box front plate 1 leaves the sea surface, Although the octopus may be discharged together with the seawater, the box rear face plate 3 is formed into a square-cut shape with a square corner dropped, and a drain hole is formed between the four corners of the box body 6 as shown in FIG. If the gaps 14, 14... Formed are formed, most of the seawater accumulated in the box is released into the sea before the octopus inlet 2 leaves the sea surface. The octopus is prevented from being discharged together with seawater at the moment of leaving.

In addition, the rope hole 4 and the insertion hole 5 of the cue stick provided in the box rear plate 3 are also used to release the seawater in the box from the octopus inlet 2 by opening the box of the octopus box lifted from the sea to the atmosphere. Although it has a function as a hole, these holes 4 and 5 are provided in the center of the box rear plate 3 where the body of the octopus contained in the box is most easily touched. There is a risk of not functioning as a drain hole. Moreover, if many drain holes are provided in the box rear face plate 3 in order to eliminate this fear, the strength of the box rear face plate 3 may be reduced, and the box rear face plate 3 attached to the branch rope of the long line may be damaged. There is.

On the other hand, as in the embodiment, the box rear face plate 3 is formed into a square-cut shape with a square corner dropped, and the box body portion 6 having the lowest possibility of being touched by the body of the octopus entering the box. If the gaps 14, 14,... That form drain holes are formed between the four corners, the concern that all drain holes are blocked by the octopus body and cannot perform the drain function is eliminated. At the same time, the strength reduction of the box rear plate 3 can be minimized.

In addition, in the Example, although the fitting convex part 11 is formed with a plurality of angled convex ridges, and the fitting concave part 12 is formed with a plurality of V-shaped grooves, it fits with the fitting convex part of the present invention. The shape and number of the concavities are not limited to this. Further, the positioning projections 13 are formed on the inner surface of the horizontal plate portion a of the L-shaped angle plate 7, but the inner surface of the vertical plate portion b or the inner surfaces of both the horizontal plate portion a and the vertical plate portion b. The shape of the protrusions is not limited to the shape shown in FIGS.

The present invention contributes to reducing the cost and improving the reliability of plastic octopus boxes used for bottom longline fishing such as octopus.
