[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an attitude control device for a marine vessel, for example, used in a motor boat, and more particularly to an improvement in an operation mechanism for easily controlling the attitude of a hull.

[0002]

2. Description of the Related Art Conventionally, a motor boat is provided with a posture control device for controlling the left and right inclinations of a hull, for example, when sailing under strong crosswinds. This attitude control device is configured such that left and right flap plates are vertically swingably mounted on both left and right sides of the stern, and the respective flap plates are vertically swung by respective hydraulic cylinders.

In order to perform a flap operation of such an attitude control device, conventionally, as shown in FIGS. 8 (a) to 8 (g), a hull is operated by an operation switch 20 having left and right operation buttons 24 and 25 of a control mechanism. 21 left and right flap plates 22 and 23
Is raised and lowered. When the left operation button 24 of the operation switch 20, for example, is operated to the down 24b side (marked with ●), the left flap plate 22 is lowered (FIGS. 8A and 8A).
(b)), a lift is generated to lower the hull 21 on the starboard 21a side. Also, press the right operation button 25 down 25
When operated to the b side, the right flap plate 23 descends (FIG. 8 (c),
As shown in FIG. 8D), a lift is generated that lowers the port 21b side of the hull 21. Furthermore, left and right operation buttons 24,
8 is simultaneously operated to the down 24b, 25b side, the left and right flap plates 22, 23 are lowered (FIG. 8 (e), FIG. 8).
(f), a lift is generated to lower the hull 21 on the bow 21c side (see FIG. 8 (g)). The left and right operation buttons 24,
When the 25 is operated to the up side 24a, 25a, the left and right flap plates 22, 23 are raised.

[0004]

However, the above-mentioned conventional attitude control device has a structure in which each of the four operation buttons is operated to raise and lower the left and right flap plates. Is difficult to operate.

In the conventional control device, for example, the left operation button is used to operate the left flap plate, and the right operation button is used to operate the right flap plate. Therefore, the position of the operated button and the inclination of the hull are reversed. ing. For this reason, the button operation does not match the behavior of the hull, and it is difficult to operate from this point as well. Further, with the above-mentioned conventional operation buttons, the operation amount of the flap plate is difficult to understand, and it is necessary to judge by considering the inclination amount of the hull, and from this point, there is a problem that the operability is low.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and has as its object to provide a marine vessel attitude control apparatus capable of improving operability and easily controlling the attitude of a hull.

[0007]

According to the first aspect of the present invention, the inclination of the hull is controlled by swinging the left and right flap plates disposed on the left and right sides of the stern upward or downward. In one of the ship attitude control devices, one operation lever is turned around the hull longitudinal axis (Y axis) and the horizontal axis (X axis).
A scale plate is provided so as to be swingable around, and a scale plate is provided in the middle of the operation lever so that the amount of swing of the operation lever can be visually checked by relative movement with a panel fixed to the hull side. An operating mechanism for swinging the left and right flap plates upward or downward by swinging is provided. The invention according to claim 2 is characterized in that the operation mechanism is configured to make the swing direction of the operation lever coincide with the inclination direction of the hull.
It is characterized in that the operating mechanism is configured to make the amount of swing of the operating lever proportional to the amount of tilt of the hull.

[0008]

According to the first aspect of the present invention, the left and right flap plates are operated by one operation lever. Therefore, when the operation lever is moved, for example, in the front-rear direction. Is that, when both flaps are moved up and down and moved in the left and right direction, one of the flaps is moved up and down, so that the complicated operation of operating the conventional four buttons can be dispensed with. Also, the posture control operation can be easily performed. In addition, since the amount of movement of the operation lever is made visible by relative movement between the hull side panel and the scale plate, even a beginner can easily operate the boat.

According to the second aspect of the present invention, the swinging direction of the operation lever and the inclination direction of the hull are made to coincide with each other, so that it is not necessary to perform the operation of the operation buttons and the behavior of the hull as in the related art. The hull attitude can be controlled by intuitive operation, and operability can be improved.

Further, according to the third aspect of the present invention, since the amount of swing of the operation lever is made proportional to the amount of inclination of the hull, the inclination state of the hull can be known from the amount of operation of the lever. Can be eliminated, and operability can be improved from this point as well.

Is detected, and a flap position signal corresponding to the detected value is output.

Next, the operation and effect of this embodiment will be described. First, when the first operation mechanism 13 installed on the cabin side is used, the joystick 17 is inserted into the opening 15.
a is located at the lower end (0, 0) in the figure (see FIG. 1A). Thereby, the first operation mechanism 13 becomes operable, and the light emitting diode 18a is turned on. When switching to the second operation mechanism 14, the joystick 17 on the side of the mechanism 14 is located at the lower end (0, 0) to enable the operation on that side, and the light emitting diode 18b is turned on. It is to be noted that the operation performed later in time has priority.

Here, the control unit controls the right flap plate 3b with a control amount of (−x + y) with respect to the x and y coordinate signals, and controls the left flap plate 3b.
a is controlled by a control amount of (x + y). Here, the control amount 0 means moving the flap plate to the uppermost end, and the control amount 10 means moving the flap plate to the lowermost end.

As shown in FIG. 1A, the joystick 1
7 is pulled to the front and positioned at the lower end (0, 0) of the opening hole 15a in the figure, the control amounts of both the left and right flap plates 3a, 3b become 0, and the control signals from the control unit 12 according to the control amounts are output. The signals are output to the pump 7, the solenoid valves 10a, 10b, etc., whereby the left and right flap plates 3a, 3b are both raised to the uppermost ends (FIG. 1 (b)).
Bow is up.

As shown in FIG. 1C, when the joystick 17 is moved to the left end (-5, 5), the control amounts of the left and right flap plates become 0 and 10, and the right flap plate 3b is moved to the lowermost position. And the left flap 3a rises to the uppermost end (FIG. 1 (d)), thereby generating a lift that lowers the port 1b side of the hull 1.

As shown in FIG. 1 (e), when the joystick 17 is moved to the right end (5, 5), the control amounts of the left and right flap plates become 10, 0, and the left flap plate 3a
Is lowered to the lowermost end, and the right flap plate 3b is raised to the uppermost end (FIG. 1 (F)), thereby generating a lifting force for lowering the hull 1 on the starboard side 1c side.

Further, as shown in FIG. 1 (g), when the joystick 17 is moved to the upper end (0, 9) in the figure, the control amounts of the left and right flap plates 3a, 3b become 9, 9 and both become the maximum. It descends to the lower end (FIG. 1 (h)), thereby generating a lift that lowers the bow of the hull 1. When the joystick 17 is moved to a position other than the above example, x,
A control amount corresponding to the y coordinate is calculated, and each flap plate moves to a position corresponding to the control amount.

As described above, according to the present embodiment, the joystick 17 is moved back and forth and left and right to raise and lower the left and right flap plates 3a and 3b. It is not necessary to perform a complicated operation, and a novice user can easily perform the operation.

Further, since the moving direction of the joystick 17 and the inclination direction of the hull 1 are made coincident with each other, it is not necessary to perform the operation of the operation buttons and the behavior of the hull as in the prior art. The attitude of the hull can be controlled and operability can be improved.

Further, in this embodiment, the joystick 1
Since the operation amount 7 and the movement amounts of the left and right flap plates 3a and 3b are made substantially proportional, the inclination state of the hull 1 can be easily known from the operation amount of the joystick 17, and the conventional intuition is used. The operability can be improved by eliminating the need for operation.

In the above embodiment, the operation range of the joystick is a diamond, but the operation range is not limited to this. For example, as shown in FIG. 7, the panel 15 is used to set the operation range linked to the behavior image of the hull.
May be a triangle. In this case, the y coordinate is also stamped on the panel 15. In addition, if the control amount is obtained by the same formula as that of the diamond, the control value may be a negative value. Therefore, if the calculation result is negative, the calculation is performed as 0.

[0028]

As described above, according to the ship attitude control apparatus of the present invention, the left and right flap plates are operated by one operation lever, and the relative movement between the scale plate and the hull side panel is achieved. Since the swing amount of the operation lever can be visually checked by the operator, complicated operations can be eliminated, and there is an effect that even a beginner can easily perform the operation. According to the second aspect of the present invention, since the swing direction of the operation lever is made to coincide with the inclination direction of the hull, the attitude of the hull can be controlled by an intuitive operation, and the operability can be improved. Further, according to the third aspect of the present invention, since the swing amount of the operation lever is proportional to the inclination amount of the hull, the inclination state of the hull can be known from the operation amount of the operation lever, and the operation relying on conventional intuition becomes unnecessary. Has the effect of improving operability.
