【考案の詳細な説明】 本考案は船で曳行して漁獲を得るためのトロール網に関
するものである。[Detailed Description of the Invention] The present invention relates to a trawl net that is towed by a boat to obtain a catch.

一般にこの種のトロール網は、所定の漁場内において、
盲曳きして漁獲を上げようとするものであり、そのため
に魚族を広い範囲に亘って捕獲するよう比較的大きな開
口部゛を有する誘導体部と、誘導した魚族を集めるため
の比較的長尺な集魚袋部とが連設された形状を有してい
る。Generally, this type of trawl net is used within a designated fishing area.
It aims to increase the catch by blind towing, and for this purpose, it has a guide part with a relatively large opening to catch fish over a wide range, and a relatively long guide part to collect the guided fish. It has a shape in which the fish collection bag part is connected.

そしてトロール網の曳行時に誘導体部の開口部が大きく
開くように、オツターボートを使用したり或は誘導体部
の開口部に拡網具等を取付けられたものが使用されてい
る。In order to widen the opening of the guide when the trawl is towed, an otter boat is used, or a net expander or the like is attached to the opening of the guide.

しかしながら、いづれのトロール網も水流を受けた時に
開口部が円形に開かれるように拡網具が配設されている
。However, each trawl net is equipped with a net expanding device so that the opening opens into a circular shape when exposed to water flow.

魚族は水面近くに拡がりをもって遊泳するか或は深さ方
向に縦長に遊泳するような習性をもっている。Fish have the habit of swimming in a wide area near the water surface or vertically in the depth direction.

このような習性を考えれば、盲曳きするトロール網が横
方向に広く開くか或は縦長に開いた方が漁獲が高まるこ
とは必定であるが、従来のように円形に開くと拡がりを
もった魚群を捕獲するにはその効率が著しく低下すると
いう欠点がある。Considering these habits, it is inevitable that blind trawl nets that open wide horizontally or vertically will increase the catch, but if they open circularly as in the past, they will spread out. The disadvantage is that the efficiency of catching schools of fish is significantly reduced.

本考案は、このような実情に鑑みなされたものであって
その目的は横方向或は縦方向に角形を呈して開口するよ

に縦長に遊泳する魚群の捕獲に有利になるのである。The present invention, which was made in order to achieve this objective, is a trawl net in which a guide part and a fish collection bag part are connected, so that the opening of the guide part opens into a rectangular shape when receiving a water flow. reins are attached to the upper and lower reins, a plurality of floats are attached to the upper reins of the reins, and a plurality of sinkers are attached to the lower reins, and extensions and derivative portions of the side edges of these reins are provided. A trawl net characterized in that delta-shaped resistors made of flexible material are respectively disposed across the outer surface of the fish collection bag and the opening of the fish collection bag, and the trawl net is characterized by having delta-shaped resistors made of flexible material arranged across the outer surface of the fish collection bag and the opening of the fish collection bag. Due to the resistor provided on the extension of the edge, when it is exposed to water flow, it opens in a rectangular shape, and when it opens horizontally, it opens horizontally, which is advantageous for catching schools of swimming fish, and when it opens horizontally, it opens vertically. Sometimes it is advantageous to catch schools of fish that swim vertically in the depth direction.

これらの開口に当っては漁場或は捕獲する魚族の種類に
よって選択すれば良い。These openings may be selected depending on the fishing ground or the type of fish to be caught.

次に本考案を図示の実施例により更に詳しく説明すると

３，４の縁部にそのまま延長して設けられている。The aforementioned guide section 1 and fish collecting bag section 2 have a plurality of vertical sieve net groups 6 and horizontal sieve net groups 7 in the length direction of the entire net, and the openings and connecting portions of the guide section Also, the horizontal sieve screen 7a,
7b, and vertical sieve nets 6a, 6b are also provided continuously, and these vertical sieve nets 6a, 6b extend directly to the edges of the above-mentioned upper and lower hand nets 3, 4.

誘導体部１の連結部１ｂ寄りの両側面で且つ前記上下の
手網３，４の端縁の延長部にテ゛ルタ状の抵抗体８ａ、
８ｂ、９ａ、９ｂが配設サレ、該抵抗体の後端は集魚袋
部２の開口部２ａにまで及んでいる。A resistor 8a in the form of a belt is provided on both sides of the induction body 1 near the connecting portion 1b and at the extension of the end edges of the upper and lower hand nets 3, 4.
8b, 9a, and 9b are provided with grooves, and the rear end of the resistor extends to the opening 2a of the fish collection bag portion 2.

この抵抗体は例えば帆布のような可撓性材料で形成され

又、頂部に対向する辺は、両端と中間の３個所に亘って
横の篩網７ｂに固定しその余の部分は空間部として残し
ておく。Further, the side facing the top is fixed to the horizontal sieve screen 7b at three locations, at both ends and in the middle, and the remaining portion is left as a space.

このように抵抗体を取付けることにより頂部が誘導体部
１に対し夫々外側に開き、水の抵抗を受は易い状態にし
である。By attaching the resistors in this manner, the top portions are opened outward relative to the inductor portion 1, making it easy to receive resistance from water.

尚前記した手網３，４は、第２図に示したように上部に
おいて横方向に１対、下部において同じように１対が取
付けられ曳行力の均等化を図ると共に、拡がり易くしで
ある。Furthermore, as shown in Fig. 2, the hand nets 3 and 4 described above are attached in a pair in the upper part in the horizontal direction and in the same way in the lower part, so as to equalize the towing force and to make it easy to spread. .

第４図に示した実施例は、構成的には第１〜３図のもの
と同じであり、縦方向に長く開く場合を示したものであ
る。The embodiment shown in FIG. 4 is structurally the same as those shown in FIGS. 1 to 3, and shows a case where the opening is long in the vertical direction.

従って各部の構成が同じであるため、前記実施例と同一
部分には同一符号を付しその説明は省略する。Therefore, since the configuration of each part is the same, the same parts as in the previous embodiment are given the same reference numerals, and the explanation thereof will be omitted.

但し縦方向に開がせる場合には上下の手綱の巾を狭くし
、抵抗体の上下中を若干広くするのみで良いのである。However, if you want to open the reins vertically, all you need to do is narrow the width of the upper and lower reins and make the upper and lower middles of the resistor slightly wider.

り、手網３，４が必然的に上下に開くのである。When the trawl net of the present invention having the above configuration is towed in the sea, the whole is dragged through the hand nets 3 and 4 provided above and below, and the upper hand net 3 is floated upward by the float 5 of the upper hand net 3. , the lower reins sink due to the sinker 14, and the hand nets 3 and 4 inevitably open up and down.

そして曳行によって各抵抗体８ａ、８ｂ、９ａ、９ｂが
前面側から水流を受けると、夫々が外側に開き、誘導体
部１の開口部が全面的に大きく拡がるのである。When each of the resistors 8a, 8b, 9a, and 9b receives a water flow from the front side by being towed, each resistor opens outward, and the opening of the dielectric portion 1 widens over the entire surface.

行えると云う優れた効果を奏するのである。As explained above, in the trawl net of the present invention, reins are attached above and below the opening of the guiding part, a plurality of floats are attached to the upper rein, and a plurality of sinkers are attached to the lower rein, and these Because it has a configuration in which a delta-shaped resistor is arranged at the extension of each side edge of the hand net, and also across the outer surface of the guide part and the opening of the fish collection bag, it can be used as a bridle with floats and sinkers. Due to the relationship with the resistor, when receiving water flow, the opening of the dielectric part opens in a horizontally or vertically long rectangular shape,
This makes it extremely advantageous for catching fish that swim close to the water surface or fish that swim deep in the water depth direction, and when expanding into a square shape, the opening can be shaped into the desired square shape only by water flow resistance without the need for a frame material etc. Since it can be opened, the structure is simple and the net can be easily handled, which is an excellent effect.
