(Mooring by mooring equipment)
A procedure for mooring using the mooring device 1 at a mooring point such as a landing will be described below. First, as shown in FIG. 1, while the position of the mooring device 1 where the arm 3 stands up and the position of the mooring column 8 are made to correspond to each other, a ship occupant is provided with the longitudinal propulsive force of the small ship 9 and the small ship 9. The side thruster is automatically controlled so that the side of the small vessel 9 is brought close to the side surface of the mooring point 10 such as a landing area within 50 cm. At this time, the arm 3 is extended.

  Next, under the remote control of the occupant's mooring device 1, the arm 3 is rotated to the mooring point side by the motor drive of the driving means 5 so as to be in a lateral position, and the mooring column is attached to the loop portion 7 of the mooring line 4. Pass 8 See Figure 2

  Next, the mooring line 4 is drawn by the driving means 5 using motor drive, the loop portion 7 is reduced in diameter, and the mooring column 8 is tightened by the mooring line 4. See Figure 3

  Next, the arm 3 is contracted so that the cylinder 31 is pulled into the cylinder 30 by the driving means 5 using motor drive, and the small vessel 9 is brought close to the mooring point and brought into contact with the berth. See Figure 4

  As described above, the driving means 5 maintains the arm 3 in the lateral position in which the arm 3 is inclined in the horizontal direction, and the mooring line 4 is kept tightened, and the contracted arm length of the arm 3 is maintained. Will be moored stably at the mooring point, allowing passengers to get on and off.

  The above-described movement in the mooring device 1 is configured to be performed by being remotely controlled by a passenger in a steering seat of a small boat. Therefore, when mooring a small vessel, it is not necessary to have a worker wait at the mooring point.

  Similarly, when leaving the mooring point, it is provided so as to be remotely controlled from the crew of the small ship, and the mooring line 4 is extended while the arm 3 is placed in the lateral position. After the diameter of the loop portion 7 is increased, the mooring line 4 can be detached from the mooring column 8 without requiring manual operation by operating the driving means 5 so as to rotate the arm 3 in the standing direction. Is provided. Of course, even when the mooring line 4 is fed out at the time of berthing, the loop portion 7 has an annular shape, and the mooring line 4 can be smoothly removed from the mooring column 8.

  FIG. 5 and FIG. 6 schematically show a configuration example of expansion and contraction of the arm 3 and a configuration example of expansion and contraction of the loop portion 7 in the drive structure of the mooring device 1, and FIG. FIG. 6 shows a state where the arm 3 is contracted and the loop portion 7 is reduced in diameter.

  A winch shaft 11 connected to the drive motor of the drive means 5 is incorporated in the pivot portion of the cylindrical body 30 of the arm 3. One end of the mooring line 4 is connected to the winch shaft 11, and the mooring line 4 passes through the inside of the arm 3 to the guide 6 attached to the distal end side of the cylindrical body 31 of the arm 3, Furthermore, it is exposed to the outside from one through hole 12 of the guide 6, and the loop portion 7 is formed at the exposed portion, enters the other through hole 13 of the guide 6, and enters the through hole 13. The other end of the mooring line 4 is fixed to the guide 6 by caulking.

  As described above, the portion of the mooring line 4 that is formed into an annular shape by the guide 6 and the mooring line 4 is a steel cable, so that the loop portion 7 is provided in an annular shape with appropriate rigidity. It has been.

  A stopper 14 is caulked and fixed in the middle of the mooring line 4, and the mooring line 4 reaching the through hole 13 from the position of the stopper 14 is coated with a resin covering material 15. The mooring line 4 is wound around the winch shaft 11 so that the mooring line 4 forming the loop portion 7 is drawn into the arm 3 through the through hole 12 of the guide 6.

  Since the mooring line 4 forming the loop portion 7 is coated with the covering material 15, the mooring line 4 enters and exits with good sliding properties with respect to the through-hole 12, and the through-hole 12 is also covered. The diameter is slightly larger than the outer diameter, and the slidability is improved from this point.

  A spring (compression coil) 16 is wound around the mooring cable 4 from the base end side of the cylindrical body 30 of the arm 3 to the stopper 14. The portion of the mooring line 4 until the spring 16 corresponds to the stopper 14 and the base end side of the cylindrical body 30 is always extended while resisting the winding force of the winch shaft 11. Thus, the mooring cable 4 is unwound from the winch shaft 11 and the stopper 14 comes into contact with the guide 6 at the tip of the cylindrical body 31 so that the arm 3 is extended.

  Further, the winch shaft 11 rotates in the winding direction while resisting compression of the spring 16 by the electric motor of the driving means 5, so that the mooring cable 4 in the loop portion 7 passes through the portion of the through hole 12 of the guide 6. As a result, the loop portion 7 is drawn into the inside of the arm 3 and the diameter of the loop portion 7 is reduced.

  Further, when the winding of the winch shaft 11 is rotated, the arm 3 contracts so that the cylindrical body 31 enters the cylindrical body 30, and when the base end portion of the guide 6 contacts the cylindrical body 30, the winch. The rotation of winding of the shaft 11 is stopped, and the driving means 5 is provided to operate so as to maintain the contracted state of the arm 3.

  When enlarging the reduced loop portion 7, the winch shaft 11 rotates in the direction opposite to that described above so that the mooring cable 4 is fed out under the control of the driving means 5, thereby maintaining an annular shape. The diameter of the loop portion 7 is increased. In addition, the arm 14 is provided so that the arm 3 extends when the stopper 14 that moves along with the extension of the spring 16 contacts and pushes the guide 6 inside the cylinder 31.

  It should be noted that one electric motor is shown as a drive source in the configuration example of expansion and contraction of the arm 3 and the configuration example of expansion and contraction of the loop portion 7 (feeding out and retracting the mooring cable 4). Another unillustrated drive motor is used, and these drive motors constitute a drive means.

  As described above, the drive means can be a combination of a plurality of drive motors for controlling the movement of each part. However, the present invention is not limited to the above configuration example, and a single drive source. A mechanism that can control the movement of each part may be provided.
