Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handle device for remote control of a ship suitable for use in a ship equipped with a Z-type propulsion device.

In recent years, as maritime traffic has become increasingly congested, more and more tugboats are equipped with Z-type propulsion devices that can freely change the direction of their thrust through 360 degrees, allowing them to safely and quickly move large ships away from and berth. It's coming.

By the way, the remote control handle device for a ship equipped with the above-mentioned Z-type propulsion device generally operates the propulsion devices installed on both the starboard and starboard sides by tilting a single control handle supported at one point below in an arbitrary direction. The propeller thrust direction is controlled in conjunction with the left and right propellers to control the direction of the ship.

However, since the control handle is supported at one point downward, it is difficult to move the control handle slightly when the control handle is tilted to its maximum position.
It is extremely difficult to maintain a constant value. As a result, it has become difficult to make minute maneuvers in a desired direction, resulting in problems such as overruns and meandering of the ship.

The present invention has been made in view of the above circumstances, and its purpose is to provide a handle device for remote control of a ship, which allows fine maneuvering of the ship in a desired direction with ease. Hereinafter, the present invention will be explained in detail with reference to the drawings.

1 to 3 show an embodiment of the present invention. Reference numeral 1 denotes a handle. At the center of the handle 1, a central shaft 2 is supported at its lower end, and is fixed in any direction. It is provided so that it can be tilted up to an angle. And this central axis 2
If you tilt it in any direction, the ship will move in that direction. Further, a hollow cylindrical body 4 is placed over the outer periphery of the central shaft 2 via a bearing 3, and this cylindrical body 4 can rotate around the central shaft 2. The bearing 3 is fixed by a snap spring 5, and a knob 6 is provided at the upper end of the cylindrical body 4. Furthermore, around the handle 1, at the position where the handle 1 is tilted to its maximum (maximum tilt position),
An annular restraint frame 7 is provided so as to be in contact with the cylinder 4, and the surfaces where the restraint frame 7 and the cylinder 4 come into contact are provided with knurled anti-slips 8 and 9, respectively, to increase the frictional effect. ing. As a result, when the outer circumferential surface of the cylinder 4 is brought into contact with the restraint frame 7 and the cylinder 4 is rotated about the central axis 2, the cylinder 4 is moved to the restraint frame 7.
The central shaft 2 rolls without slipping against the restraining frame 7, thereby causing the central shaft 2 to move along the restraint frame 7. Note that when the central axis 2 is tilted in any direction, the ship moves in that direction; however, when this central axis is tilted in any direction, the ship moves in that direction according to the angle The structure may be such that the speed changes as the speed changes.

Next, the operation of the handle device for remote control of a ship according to the present invention will be explained.

First, if you want the boat to travel in a certain direction, you just need to grip the steering wheel 1 and tilt it in the desired direction. At this time, if the handle 1 is tilted to the maximum inclination position so that the outer peripheral surface of the cylinder body 4 is in contact with the restraint frame 7, the surfaces of both the restraint frame 7 and the cylinder body 4 of the handle 1 will have a knurled finish. Since the stops 8 and 9 are provided, it can be easily held at that position. Next, if it is necessary to make a slight change in the direction of the vessel with the handle 1 tilted to its maximum tilt position, rotate the knob 6 while keeping the cylindrical body 4 in contact with the restraint frame 7. good. Then,
The cylinder body 4 rotates around the central axis 2, and the cylinder body 4 rolls against the restraint frame 7, whereby the handle 1
will move along the restraint frame 7, so the ship can change its direction. Note that instead of rotating the knob 6, it is of course possible to directly rotate the cylindrical body 4.

As explained above, the handle in the device of the present invention is composed of a central shaft and a cylindrical body that is rotatably fitted in the circumferential direction on the outside of the central shaft and can roll with respect to the restraint frame. Not only can the handle be held in a fixed position by pressing the cylinder against the restraint frame, but also the handle can be moved along the restraint frame by rotating the cylinder and rolling it against the restraint frame. As a result, it is possible to perform fine maneuvering operations, resulting in extremely safe and stable boat maneuvering, which is an excellent effect. In addition, by attaching anti-slip pads to the contact surfaces of the restraining frame and the cylinder, it is possible to reliably prevent the cylinder from slipping against the restraining frame, and it is possible to reliably hold the handle in a fixed position. This has the advantage that the cylindrical body can be reliably rolled relative to the restraint frame.
