Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a towed ship that is towed by a towed ship to perform various operations.

[0002]

2. Description of the Related Art Conventionally, there is known a towed ship that is not equipped with a propulsion device and that travels on water by being towed by a towed ship. The towed ship is towed by being connected to the towed ship by an appropriate rope.

[0003]

In the above structure, the rope is loosened due to the speed difference between the towed ship and the towed ship during traveling, and the relative position of the two ships (distance between the two ships).
Will change. Therefore, during towing, sudden turning and sudden deceleration are limited, the degree of freedom of driving such as acceleration / deceleration and turning is also extremely limited, and the exercise performance is significantly reduced. In order to eliminate such inconvenience, it is conceivable to connect the two ships with a rigid connecting means, but in this case, the two ships will move integrally, so that the towing of the towing ship, etc. Movement will also be constrained, which will also significantly reduce motor performance. Further, the towed ship itself has a problem in that it is difficult to exhibit its kinetic performance satisfactorily because it is restricted by the movement of the towed ship.

The present invention has been made in order to solve the above-mentioned conventional drawbacks, and an object thereof is to provide a towed ship having a structure capable of sufficiently exhibiting the exercise performance. is there.

[0005]

According to the present invention, the bottom of a ship is a catamaran ship type, and a boarding deck is formed from the vicinity of the center of the hull to the rear part, and the boarding deck is gripped in a standing posture around the boarding deck. A handrail is formed and a connecting means for towing is provided on the bow portion.

[0006] It is preferable that the connecting means is constructed so that the towed ship and the towed ship can roll and change their relative directions, and their intervals cannot be changed. A storage compartment may be formed on the front side of the boarding deck, and an outboard motor mounting portion may be formed on the stern end of the hull. The handrails are preferably formed on the front and both sides of the boarding deck.

[0007]

In the above structure, when turning, a person standing on the boarding deck tilts the towed ship while grasping the handrails around it, so that only one side of the buoyancy body is flooded. As a result, the substantial ship width is greatly reduced, and thereby the ship can be easily tilted in the ship width direction, and the attitude of the boat can be smoothly changed in accordance with the movement of the towing ship. Moreover, since the bottom of the towed ship has a catamaran-shaped boat with lateral stability, the boat can be tilted greatly without overturning, and a large change in attitude of the towed ship can be stably performed according to the movement of the towed ship. You can

1 to 3, the towed ship 10 is an FRP.
The hull member 11 and the deck member 12, which are integrally molded products, are joined to each other at their peripheral portions, and the bottom of the ship is formed into a catamaran ship type. That is, as shown in FIG. 3, buoyant body portions 17 are formed symmetrically to each other on the left and right sides and extend in the lengthwise direction, and recesses 18 are formed between them.
Further, a boarding deck 2 is formed from the vicinity of the center of the hull to the rear part, and the boarding deck 2 is formed with bulwarks 13 on both sides, the rear part is opened, and the boarding deck 2 is flat in the front area A. The region B on the rear side is inclined rearward and upward, and the region C on the rear side is formed as a flat surface. A storage case 4 is formed on the front side of the boarding deck 2, and a cover 40 that can be opened and closed by a person 19 on the boarding deck 2 is attached to the upper side of the storage case 4. A rising wall 21 which is a rear wall of the storage case 4 forms a front wall of the boarding deck 2, and a cushion 22 is attached to the rising wall 21. As shown in FIG. It is used as a reliance.

Around the boarding deck 2, there is formed a handrail 3 which is gripped in a standing posture, and the handrail 3 is formed in an arc shape over the front side and both side portions of the boarding deck 2. The stern side of the boarding deck 2 is open, and a projecting portion 20 projecting upward is formed near the rear end of the boarding deck 2 so that a person 19 in a standing posture can support his / her feet, as shown in FIG. ing. Further, the outboard motor 6 is attached to the transom 15 at the central portion on the rear side as shown in FIG.

Further, a towed connecting means 5 is provided on the hull member 11 at the end of the bow, and the connecting means 5 is made of metal and has a rigid structure and is formed as shown in FIGS. 5 and 6. There is. That is, an A-shaped frame is formed by the pair of main members 51 and the connecting member 52 connecting them, and the tubular member 53 is provided on the top thereof. This tubular member 53
The intermediate member 54 rotatably passes through the through hole 530 of
A projecting shaft 55 projecting laterally is integrally formed with the intermediate member 54. The protruding shaft 55 is used for the towing ship 1
The locking member 56 mounted by the mounting bolt 101 so as to be located at the center of the stern of the ship 00 in the ship width direction is rotatably penetrated and is prevented from coming off by the nut 550. A pair of abutting plates 57 are attached to the bow end deck member 11 of the towed ship 10 by mounting bolts 110. A projecting member 58 is provided on the abutting plate 57, and the tip end portion of the projecting member 58 is the main member. 51 and pin 510 are connected.

In the above structure, when the towed ship 10 is towed, the towed ship 10 is connected to the towed ship 100 by the connecting means 5 as shown in FIG. 4, and the person 19 stands on the boarding deck 2 in a standing posture. Grab the slide 3 and ride. Towed ship 1 in this state
When 00 is driven, propulsive force is generated by ejecting water from the water injection port 103 of the propulsion unit of the towing vessel 100,
The towed ship 10 is towed while towing. Water jet 103
The water ejected from the water is sent rearward through the recess 18 at the bottom of the towed ship 10, so that the jetted water hits the towed ship 10 and the propulsion efficiency is reduced.

When turning, the towed ship 10 can be easily tilted largely while the person 19 holds the handrail 3. That is, when the towed ship 10 is tilted, as shown in FIG. 3, the water line 90 when going straight becomes the water line 91 when tilted, and in this state, only the buoyancy body portion 17 on one side is flooded. The actual ship width is greatly reduced, making it very easy to tilt in the ship width direction,
Therefore, it is possible to enjoy the exercise that changes the degree of inclination.

Further, in the towed state, the connecting means 5 is constructed so that the towed ship 100 and the towed ship 10 can roll and change their relative directions, and the distance between them does not change. That is, as shown in FIGS. 5 and 6, since the connecting means 5 is made of a rigid member as a whole, it cannot be compressed and deformed in the length direction, and the projecting shaft 55 does not move with respect to the locking member 56. Since the towed ship 100 and the towed ship 10 can rotate about the axis of the projecting shaft 55, relative rolling of the towed ship 100 and the towed ship 10 is possible. Since the main member 51 is rotatable with respect to the intermediate member 54 within the plane of FIG. 6, the towed vessel 100 and the towed vessel 10 can change their relative directions. . Therefore, in normal towing conditions,
The towed ship 10 travels while performing relative rolling and relative direction change with respect to the towed ship 100, and there is no risk of collision between the two ships due to the speed difference, so acceleration and deceleration operation is not possible. You can do it freely.

Further, since the storage case 4 is formed in a dead space portion of the towed ship 10, the space can be effectively used, and the storage case 4 should accommodate small articles for the person 19. . Further, as shown in FIG. 1, it is also possible to attach the outboard motor 6 to the transom 15 at the stern of the towed ship 10 and allow the towed ship 10 to travel by itself.
