Description

DETAILED DESCRIPTION OF THE INVENTION The invention of the present application relates to a control device when two outboard motors are mounted side by side on a watercraft for dual-engine operation.

Conventionally, dual outboard motor operation has been performed using remote control as shown in FIG. 1.

In other words, a steering wheel 2 is installed in front of the driver's seat of the boat 1, and a twin control box 3 is installed next to the driver's seat. The steering rod 6 and the steering wheel 2, which are rotatably connected, are connected by a steering cable 7, and the throttle mechanism and clutch lever of each outboard motor and the control box 3 are connected by two throttle cables 8 and two clutch levers. By connecting the two outboard motors with a cable 9, the two outboard motors can be operated simultaneously from the driver's seat.

It is necessary for the boat to carry out this two-engine operation to be equipped with a steering device in advance.
It must be possible to install a control box. That is, the structure becomes complicated and large-scale, and the cost becomes high.

Furthermore, mounting the device requires a great deal of effort. Therefore, what is even more important is that if two outboard motors are installed on boats that do not have steering devices, such as general small fishing boats, it is not possible to operate the two at the same time. It is desirable to be able to directly operate two outboard motors while standing next to the outboard motor.

The two-engine control system of the present invention eliminates this drawback, and by simply connecting the throttle mechanisms of two outboard motors with a cable mechanism, two outboard motors can be operated by simply operating the bar handle of one outboard motor. This made it possible to control the speed and steer the outboard motor. By connecting the clutch levers of two outboard motors using a similar cable mechanism, it is also possible to simultaneously switch the clutches of two outboard motors by operating one clutch lever.

An embodiment of the present invention will be described below with reference to FIG.

FIG. 2 shows Example 1 of the present invention. Two outboard motors 4 and 5 are fixed side by side to a mounting plate at the stern of a watercraft.

A steering rod 6 is rotatably connected to the steering brackets of two outboard motors for dual-engine operation.
If the distance between the two outboard motors and the length of the steering rod 6 are adjusted to be equal, the two outboard motors will tilt by the same angle when rotating relative to the boat. This steering rod 6 is also necessary when steering by remote control using a steering device as shown in FIG.

The throttle control mechanism for the first outboard motor 4, which is manually operated, will now be explained. Reference numeral 12 denotes a bar handle, which is attached to the steering bracket of the outboard motor and can be rotated left and right with respect to the fixing bracket together with the outboard motor main body.

A handle grip 13 is attached to the tip of the bar handle 12 so as to be rotatable about the axis of the bar handle.

A throttle shaft 14 is fixed to the handle grip 13 and rotatably held inside the bar handle 12. The tip of the throttle shaft 14 extends inside the outboard motor, and is attached to a shaft 17 on the side of the engine via a handle link rod 15.
The throttle arm 16 is connected to the tip of a throttle arm 16 that is rotatably attached to the throttle arm 16.

The throttle arm 16 has three tips, one
The handle link rod 15 is connected to one end 16a, and the throttle link rod 18 is connected to the second end 16b.The opposite end of the throttle link rod 18 is connected to the carburetor throttle (not shown). It is connected to the shaft arm or the arm of the magneto base plate.

That is, when normally operating an outboard motor, grasp the handle grip 13 and swing it from side to side to perform steering.When the handle grip 13 is rotated, the throttle arm 16 is rotated, and the outboard motor can be directly or propelled. Through rotation of the magneto base plate for angle control, the carburetor throttle shaft arm can be rotated to open and close the throttle valve, that is, to control the speed of the outboard motor. Throttle shaft 1
In some cases, a pair of pinions is provided in the middle of the bar handle 12 so that the bar handle 12 can be folded.

Also, the third tip 16C of the throttle arm 16
is a reserve, and in case of remote control, a throttle cable is connected here and the throttle arm 16 is rotated by operating the lever of the control box to control the speed.

The above are typical known structural examples of a throttle control mechanism for an outboard motor. The present invention enables the operation of the second outboard motor 5 by operating the handle grip 13 of this one outboard motor.
At the same time, the throttle control will be performed.

19 is a cable provided according to the present invention. The outer end 20a of the cable 19 on the outboard motor 4 side is removably fixed to a cable clip 21 rotatably attached to the tip 16C of the throttle arm 16, and the inner cable 22a is rotatably removable. It can be attached to an appropriate location on the outboard body.

The end of the cable 19 on the outboard motor 5 side is connected to the outer 2
0b is removably fixed to a cable grip 23 attached to the outboard motor body, and the inner 22b is rotatably and detachably attached to the third end 16C' of the throttle arm 16'.

In the first embodiment of the present invention configured as described above, when the handle grip 13 of the outboard motor 4 is rotated in the direction of the arrow, the throttle arm 1 is rotated through the movement of the throttle shaft 14 and the handle link rod 15.
6 in the direction of the arrow. In this case, the throttle arms 16, 1 of the outboard motors 4, 5, respectively.
Between 6' and 6', the cable 19 is connected to the outer on one side and the inner on the other, so the other throttle arm 16' also moves in the same direction by the amount that the throttle arm 16 moves. .

Both ends 22a and 22b of the inner cable 19 can be attached by adjusting the inner length, and are attached to the two throttle arms 16 and 16'.
You can keep the angles of the two sides aligned.

Since the advance angle of the magneto and the opening and closing of the throttle valve are controlled by the movement of each throttle arm, the throttles of two outboard motors can be controlled simultaneously and in the same way by rotating one handle grip 13. . Since the two outboard motors 4 and 5 are connected by the steering rod 6, when the handle grip 13 is swung left and right, the outboard motors 4 and 5 are both tilted in the same direction by the same angle, allowing steering. . In this case, when using a relatively large outboard motor, steering operation for two-engine operation becomes difficult using a standard bar handle. In this case, it is possible to lighten the steering by replacing the handle with a long-handled bar handle designed specifically for dual-engine operation.

In the first embodiment, the cable clip 23 of the outboard motor 5
The fixing part is provided on all outboard motors as a fixing part for the throttle cable for remote control. By preparing only the cable mechanism or a bar handle for two aircraft as an option, a two-engine control system can be realized quickly and inexpensively by simply attaching these.

Embodiment 2 of the present invention is shown in FIG. Two cables 30 and 31 are required.

The outer ends 32a, 32b of the cable 30 are attached to the first outboard motor 4 with cable clips 33, 3, respectively.
4, it is removably fixed. As for the fixing part of the cable clip, one can use the throttle cable fixing part for remote control as is, and the other can use the handle part of the bar handle 12, etc. One end 35a of the inner part of the cable 30
is rotatably and removably attached to the third tip 16C of the throttle arm 16, and the other end 35b of the inner is rotatably attached to the bar handle or the like of the first outboard motor 4 about the fulcrum 36. The first end portion 37a of the direction change lever 37 is rotatably and removably attached.

On the other hand, one outer end 38a of the cable 31 is detachably attached to the outboard motor 4 via a cable grip 39, and the other outer end 38b is detachably attached to the second outboard motor 4 via a cable grip 40. It is attached to the fixed part of the remote control throttle cable in No. 5.

One inner end 41a of the cable 31 is rotatably and detachably attached to the second tip 37b of the direction change lever 37, and the other end 41b of the cable inner is attached to the third end 41a of the throttle arm 16' of the outboard motor 5. It is rotatably and removably attached to the tip 16C'.

In the second embodiment configured as described above, when the handle grip 13 of the first outboard motor 4 is rotated in the direction of the arrow, the throttle arm 16 is rotated in the direction of the arrow, and the inner 35 of the cable 30 is pushed in the direction of the arrow. This force rotates the direction change lever 37 in the direction of the arrow, and further pulls the inner 41 of the cable 31. That is, the direction change lever 37 has the function of changing the movement of the inners of the two cables from pushing to pulling and from pulling to pushing. As a result, the throttle arm 16' of the second outboard motor 5 is pulled and can move in the same direction and over approximately the same length as the throttle arm 16 of the first outboard motor 4. In other words, the throttle controls of the two outboard motors can be operated simultaneously and in the same manner.

Please note here that the direction change lever 37
If the two end portions 37a and 37b have the same length from the fulcrum and the two cable inners are oriented in almost the same direction, the two inner cables 35 and 41 will move by the same amount, and the two outboard motors connected to each other will move by the same amount. If it is necessary to make the rotation angle of each throttle arm different for a different model, it is possible to change and adjust the cable inner attachment position of either of the two tips 37a, 37b of the direction change lever 37. Just leave it there.

The position of the two throttle arms can be adjusted by adjusting the inner mounting length.

The mounting portion of the direction change lever 37 and the related fixing portions of the outer fixed cable grips 34, 39 may be provided by processing the handle of the bar handle 12, or may be provided on another part of the outboard body or a bracket. It may be provided.

FIG. 4 shows Example 3.

In this embodiment, two cables 50 and 51 are used to transmit the rotational motion of the handle grip 13 and throttle shaft 14 of the first outboard motor 4 to each of the throttle internal mechanisms of the two outboard motors at the same time. This is a method of operating the throttle mechanism.

A cable inner attachment portion 52 is provided in the middle of the throttle shaft 14, and a cable inner attachment portion 52 is provided at the inner attachment portion 52.
The ends of the inner cables 53 and 54 of the two cables 50 and 51 are rotatably and detachably attached so that when the throttle shaft 14 rotates in the throttle opening direction, the two cable inners are wound and pulled. Let it be. The other ends of the two cable inners are the throttle arms 16 and 1 of each outboard motor.
Rotatable at the third tip 16C, 16C' of 6',
Can be attached removably.

One end of each cable outer is fixed to the handle part of the bar handle 12, and the other end is fixed to the fixing part of the remote control throttle cables of the two outboard bodies via cable grips.

By doing this, the rotation of the handle grip can be converted into the same movement of the throttle arms of the two outboard motors via the cable.

Throttle arms 16, 16' of embodiments 1 and 2
The cable mechanism that links the two outboard motors 4 and 5 to the same direction and motion is the same as the clutch lever 6 of the two outboard motors 4 and 5.
It can be applied to 0,60' interlocking. FIG. 5 shows an example thereof.

This figure shows the same method as the first embodiment of throttle arm interlocking.

The cable 61 is connected to clutch levers 60, 60', but the inner and outer fixings are reversed between the two units. The fixing part for the remote control clutch cable can be used as is, or a small cable fixing part or a mounting bracket for the direction change lever can be attached.

By operating the clutch lever 60 of the outboard motor 4, the clutch lever 60' of the outboard motor 5 can be caused to make the same movement, and the clutches of two motors can be switched simultaneously by operating one clutch lever.

The effects of the present invention are as follows.

The speed of two outboard motors can be controlled and steered by operating only one bar handle. If necessary, switching between two clutches can be performed by operating one clutch lever.

There is no need to equip the driver's seat with a steering device or install a remote control device.

Therefore, even a small fishing boat or the like that is not equipped with a steering device can be operated with two outboard motors.

There is no need for equipment such as a steering device in advance, and only a few dedicated parts for two-engine operation are available as options for standard outboard motors, and they can be easily installed and replaced, so the cost is low. And cheap. Moreover, the area that can be effectively used inside the boat becomes larger. Outboard motors can be used for two-engine operation by simply preparing a few cable fixing parts or direction change lever fixing parts in advance.

In terms of cost, Embodiment 1 is the cheapest because only the cables need to be connected.

Embodiment 2 requires the installation of a direction change lever.

Embodiment 3 requires a bar handle completely dedicated to two machines. However, even in the first and second embodiments, if the outboard motor is large, a long-handled bar handle specifically designed for two motors is required in order to make steering easier.

For example, when driving a boat, the load on the way out is heavy and requires two engines, but on the way back the load is small and it is economical to operate with a single outboard motor. There is also. In this case, the present invention uses a flexible wire for the cable connecting the two outboard motors, and makes the steering rod a universal type so that the outboard motor that is not being used can be tilted up and swiveled without removing the cable. You can also prevent it from becoming a running resistance.
