Abstract

(57) [Summary] [Purpose] The objective is to provide a human-powered submersible that is safe, noiseless, and does not cause marine pollution. [Composition] In a submersible driven by human power, a handle shaft having a handle at the upper end and a handle shaft at the front part are rotatably held, a saddle is fixed at the rear part, and the pedal is interlocked with the pedal at the lower middle part to rotate freely. A body frame that holds a large-diameter gear, a small-diameter gear that winds a large-diameter gear and a chain, and left and right propellers that are rotatably connected via spring joints, and rotatably held on the left and right sides under the handle shaft. It is composed of a diving rudder, left and right rudders that operate via a gear and a chain fixed to the lower end of the handle shaft, and a body cover that covers the body frame.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a submersible boat in which an occupant manually drives in water for recreation or sports.

[0002]

[Prior Art]

 Conventionally, this type of device has not been particularly devised, and self-propelled surfboards and jet skis are known as recreational or sports vehicles on the water.

[0003]

[Problems to be solved by the device]

 As mentioned in the prior art, when self-propelled surfboards and jet skis propel the beach, they endanger other beach guests, disperse noise, and use gasoline, light oil, etc. as fuel. It had a problem that it could cause marine pollution.

The present invention has been made in view of such problems of the conventional technology, and its purpose is to be safe, noiseless, and to cause marine pollution. It is intended to provide a non-human powered submersible.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention relates to a submersible propelled by human power, in which a handle shaft having a handle at an upper end, a handle shaft rotatably held at a front part, and a saddle fixed at a rear part. A body frame that rotatably holds a large-diameter gear in the middle lower part in conjunction with a pedal, a small-diameter gear that winds the large-diameter gear and a chain, and left and right propellers that are rotatably connected via spring joints. A submersible rudder that is rotatably held on the left and right sides of the lower part of the handle shaft, left and right rudders that operate via gears and chains fixed to the lower end of the handle shaft, and a body cover that covers the body frame. It is composed of the following items, and is made by a boater diving manually.

[0006]

[Action]

 The diving rudder under the handle shaft is made rotatable in conjunction with the rotation of the handle itself.

The left and right rudder can change the direction in conjunction with the rotation of the handle about the handle axis.

[0008]

【Example】

 An embodiment will be described with reference to the drawings. As shown in FIGS. 1 to 4, a handle shaft 2 having a handle 1 is provided at an upper end, and the handle shaft 2 is rotatably held at a front portion of a body frame 4. .

A saddle 5 is fixed to the rear portion of the body frame 4, a large-diameter gear 8 is rotatably held in an intermediate lower portion of the body frame 4 in conjunction with a pedal 6, and a large-diameter gear 8 and a chain 7 are wound. It is rotatably connected to the left and right propellers 12 via a small diameter gear 9 and a spring joint 10.

The submersible rudder 3 is rotatably held on the left and right sides of the lower part of the handle shaft 2, and the submersible rudder 3 is interlocked with the rotation of the handle 1 itself via an actuating shaft 17.

A gear 14 fixed to the lower end of the handle shaft 2 is wound around a chain 21 and interlocks with the gear 15. The rotation shaft of the gear 15 is connected to the left and right rudders 13 via an operating shaft 16.

The fuselage frame 4 is covered with a fuselage cover 18, a propeller duct 11 for housing the left and right propellers 12 is fixedly installed at the stern of the fuselage cover 18, and a vertical fin 19 and a vertical fin 19 are provided at the stern of the fuselage cover 18. The horizontal fins 23 are fixed, and the buoyancy adjusting ballast 20 is provided inside the body cover 18.

In this embodiment, the boater wears a simple breathing apparatus 22 that is lightweight and has a dive time of about 10 minutes, rides on a saddle 5 of a human-powered submersible, and depresses a pedal 6 to propel it. When the direction is changed to, the handle 1 is rotated around the handle shaft 2 and the rudder 13 is operated via the chain 21 wound around the gears 14 and 15.

During diving, the handle 1 itself is rotated to pull up the rear end of the diving rudder 3 by the operating shaft 17 to propel it, while at the time of ascent, push the rear part of the diving rudder 3 to propel it.

[0015]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. Since it is human-powered, it does not endanger other swimmers, improves safety, does not make noise, and does not use gasoline or light oil as fuel, so it does not cause marine pollution and protects the natural environment. Can contribute to.
