The swimming depth of the target fish varies depending on the weather, water temperature, etc. that day. However, when the submersible plate a is towed by a ship, it dives underwater, but the submersible plate a cannot be submerged to a desired diving depth. In particular, when the boat speed is changed, the diving depth of the diving board constantly changes, making it impossible to obtain a desired diving depth for any given boat speed.

In order to achieve the above object, the present invention rotatably supports a wing plate at the rear end of a towing plate that is towed by a boat and causes fishing gear to flow backward under tension. A scale plate with numbers written on it is hung vertically on the towing plate, one end of a diving angle adjustment rod extending in the direction of the scale plate is fixed to the wing plate, and the other end is attached to the scale plate so that it can be fixed freely. be.

According to the present invention having the above configuration, the wing plate is fixed at a predetermined angle by fixing the diving angle adjustment rod in accordance with the desired boat speed and desired diving depth on the scale plate. In this state, when the deep diving board is towed by a ship with the wing plate facing downward, a force corresponding to the desired ship speed and desired diving depth on the scale plate is applied upward at right angles to the wing plate. For this reason, a force acts to force the front part of the depth diving board downward, and the water current causes it to sink.
以下、第１図乃至第５図により本発明の実施例
を詳細に説明する。
Embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 5.

構成されている。 A deep diving board 1 according to an embodiment of the present invention includes a towing board 3 that is towed by a ship 2 via a towing line 2a, and a wing plate attached to a rear end 3a of the towing board 3 via a hinge 3'. 4, and a scale plate 5 hanging vertically on the towing plate 3.
and a diving angle adjustment rod 6 fixed to the wing plate 4 via a rivet 4a and extending in the direction of the scale plate 5.

果たす。 The towing plate 3 is constructed in the shape of a flat ship to reduce resistance. The scale plate 5 has a fan-shaped shape, and the surface shows the ship speed (2 knots ~
6 knots) and the diving depth (1m to 9m). Since the scale plate 5 is vertically installed on the towing plate 3, it also functions to maintain the traveling direction of the depth diving plate 1.

態となつている。 A U-shaped stop 6a and a bolt 6b are provided at the tip of the diving angle adjustment rod 6, and it is fixedly attached to the fan-shaped peripheral side surface 5' of the scale plate 5, and a hook 6c is provided at the rear end. is provided. A fishing gear 7 with an artificial bait and a fishhook is tied to the hook 6c, and the fishing gear 7 is flown behind the diving board 1 and is kept under tension.
次に、本実施例の作用を説明する。 Next, the operation of this embodiment will be explained.

にＡの位置に固定すると、翼板４は急傾斜（A1）
となる。この状態で船２が６ノツトで進むと、定
深潜航板１は水中９ｍの深度で進む。 For example, when the cruising speed of the ship 2 is set to 6 knots and the constant depth diving plate 1 is to be submerged at a diving depth of 9 m, if the diving angle adjustment rod 6 is fixed at the position A on the scale plate 5, Wing plate 4 is steeply inclined (A1)
becomes. When the ship 2 moves at 6 knots in this state, the deep diving board 1 moves underwater at a depth of 9 m.

位置に固定すると、翼板４は緩い傾斜（B1）と

潜航板１は水中１ｍの深度で進む。 When the cruising speed of the ship is set to the same 6 knots and the depth diving plate 1 is to be submerged at a diving depth of 1 m, if the diving angle adjustment rod 6 is fixed at position B on the scale plate 5, the wing plate 4 is a gentle slope (B1). When the ship 2 moves at 6 knots in this state, the deep diving board 1 moves underwater at a depth of 1 m.

位置に固定すると、翼板４は中程度の傾斜（C1）
となる。この状態で船２が４ノツトで進むと、定
深潜航板１は水中１ｍの深度で進む。 When changing the cruising speed of the ship to 4 knots and attempting to submerge the constant depth diving plate 1 at a diving depth of 1 m, fixing the diving angle adjustment rod 6 on the scale plate 5 at position C, the wing plate 4 is a moderate slope (C1)
becomes. When the ship 2 moves at 4 knots in this state, the deep diving board 1 moves underwater at a depth of 1 m.
以上のように、船速、翼板４の傾斜を所定の値
に設定すると、それに対応した潜航深度が得られ
る理由を第４図、第５図によつて説明する。 The reason why, as described above, when the ship speed and the inclination of the wing plate 4 are set to predetermined values, a corresponding diving depth can be obtained will be explained with reference to FIGS. 4 and 5.

に示すように、翼板４に作用する力Ｆが大きくな

Pvが大きくなつて、定深潜航板１の潜航深度が
深くなる。 By providing the vane plate 4, the force F perpendicular to the vane plate 4
acts, and a bending moment FL acts in a counterclockwise direction based on the tip end 3b of the towing plate 3. On the other hand, since the tip end 3b of the towing plate 3 is stretched by the towing line 2a, the constant depth diving plate 1 is rotated by the bending moment FL and forms an angle θ with respect to the horizontal plane. . Therefore, the constant depth diving board 1 receives a force F acting on the wing board 4, a tensile force T of the towing line 2a, and a force P due to the water flow. Considering the vertical balance of the constant depth diving plate 1, the force P v that causes the constant depth diving plate 1 to sink due to the water flow = vertical component of the force F acting on the wing plate 4 + the tensile force T of the towing line 2a The vertical component T v is maintained at a certain depth, and the constant depth diving board 1 is maintained in a balanced state. When the inclination of the wing plate 4 is large, as shown in FIG. 4, the force F acting on the wing plate 4 increases, and therefore, the force that causes the depth diving plate 1 to sink due to the water flow
As P v increases, the diving depth of the constant depth diving plate 1 becomes deeper.
翼板４の傾斜を変えずに船の巡航速度を大きく
すると、水流により定深潜航板１を沈める力Pv
が大きくなつて、定深潜航板１の潜航速度はさら
に深くなる。 If the cruising speed of the ship is increased without changing the inclination of the wing plate 4, the force P v that sinks the depth diving plate 1 due to the water current
becomes larger, and the diving speed of the constant depth diving plate 1 becomes deeper.
翼板４の傾斜が小さい時は、第５図に示すよう
に、翼板４に作用する力Ｆが小さくなり、従つ
て、水流により定深潜航板１を沈める力Pvが小
さくなり、定深潜航板１の潜航深度が浅くなる。 When the inclination of the wing plate 4 is small, as shown in FIG . The diving depth of the deep diving board 1 becomes shallower.

is set at a predetermined angle, and in this state, deep diving board 1
By towing at a desired speed, the constant depth diving board 1 can be submerged at a desired depth.
