Description

[Detailed Description of the Invention] This invention relates to an outboard motor, a remote control box used to remotely control the speed increase/decrease, forward/reverse switching, etc. of the outboard motor.

Generally speaking, on ships equipped with outboard motors or inboard/outboard motors that are used at sea, if the operator accidentally falls overboard or something unusual occurs, the outboard motor or inboard/outboard motor engine must be immediately turned off. A safety switch is installed to protect those who fall overboard and prevent unmanned operation of the vessel.

This safety switch has a string attached to the stopper of the switch, and is used by tying the end of the string to the operator's body. If the pilot falls into the water, the switch's stopper will be pulled by the string tied to his body, causing it to come off the switch. An electrical circuit is provided within the switch that stops the engine when the stopper is removed.

The present invention is based on the location of this safety switch when it is installed in a remote control box.

As mentioned in the previous sentence, the safety switch is attached to a string, so this string will not have any negative effect on the operating device of the remote control box, and the string will not be pulled on anything else when the operator falls into the water, allowing it to operate normally. There must be.

In the case of conventional remote control boxes, it has been common to install a safety switch on the side, rear, or top. (Figure 1,
(Fig. 2) However, when it is mounted on the side, there is a drawback that when two remote control boxes are used together, the safety switch string of the inner remote control box cannot be pulled. (Fig. 3) Also, if the safety switch is installed on the rear or top surface, the safety switch cord will generally not wrap around or get caught on the operating levers or control knobs of electrical components installed on the top, side, or rear. There are problems with operability and safety.

The present invention solves the above-mentioned problem by attaching a safety switch to the bottom of the remote control box.

To explain the present invention with reference to FIG. 4, reference numeral 1 denotes a remote control box, which is generally fixed at a position on the right side of the cockpit in a ship where it can be operated with the right hand. 2 is an operation lever for remote control, and 3 is a main switch.

4 is a remote control cable, the opposite end of which is connected to an outboard motor or an inboard/outboard motor fixed to the stern.

5 is a safety switch attached to the bottom surface of the remote control box 1 according to the present invention.

The safety switch itself is well known, and one example is shown in Fig. 6.A safety switch main body 5a is fixed to the wall of a remote control box 1 with a nut 5c, and two electric wires 5d and 5d are connected inside the box. A book is out. Reference numeral 5b denotes a switch button, which is not shown but is biased by a spring toward the safety switch body 5a. When the switch button 5b is actuated by the spring, an electric contact is closed, and it is connected to the outboard motor or inboard/outboard motor. It is built into the engine's ignition circuit and will stop the engine. A safety switch stopper 6 is sandwiched between the switch button 5b and the safety switch main body 5a, and this prevents the switch button 5b from being operated by the spring.

A string 7 is tied to the rear end of the safety switch stopper 6, and the other end of the string 7 is tied to the body of the operator.

When the operator pulls the string due to rising water, the safety switch stopper 6 easily comes off and the switch button 5b is immediately activated.

To explain the effect of this invention, as it is attached to the bottom of the remote control box as shown in Fig. 4, it is located far enough away from the operation lever 2, main switch 3, and other electrical equipment operation knobs, so that it can be easily accessed. It is no longer possible to prevent the safety switch from operating due to the string 7 becoming entangled or caught.

An example of a two-machine system is shown in Figure 5. In this case 2
In order to operate two outboard motors at the same time, two remote control boxes are mounted on top of each other, but since the safety switch is mounted on the bottom, there is no problem. Furthermore, although the safety switch cord is normally rather a nuisance, by attaching it to the bottom, it becomes less noticeable even during normal operation, and a new advantage has arisen in that the cord is no longer noticeable.
