Description

[Detailed description of the invention] This invention relates to a starting switch for motorcycles, and the operation of the engine stop switch and engine start switch, which conventionally had separate operation knobs, can be operated using a single rod-shaped switch. This feature is characterized in that it is operated using a control lever.

Conventionally, an engine stop switch (kill switch) and a engine start switch (starter switch), which are mainly used for emergencies, have been separate switches because their functions are completely opposite.

Therefore, when the engine is stopped, turn on the start switch.
There were many cases where I tried to start the engine with it turned on, but the engine would not start. This generally also activates the engine stop switch when stopped.
This is to keep the engine OFF.In this case, when starting the engine, turn the engine stop switch OFF.
You must release (ON) the engine and leave it running before operating (ON) the start switch.
However, many people forget to release the engine stop switch, and this is thought to be largely due to the fact that the engine stop switch is provided separately from the start switch.

In view of the above-mentioned circumstances, the present invention has been developed by arranging a start switch, a running switch, and an engine stop switch in series on a fixed contact plate, and providing corresponding movable contacts on a rod-shaped operating lever. With both ends protruding from the switch case, each operation is performed using a push button, so that when the start switch is activated (ON operation), the engine stop switch is automatically turned off. An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional front view of the starting switch according to the present invention installed in a switch case 2 attached to a handle pipe 1, and 3 is a rod-shaped operating lever with a movable contact 12 in the center. This operating lever has both ends protruding outside the switch case and is slidable in the axial direction.
A, b, and c are fixed contacts provided at positions corresponding to the movable contact 12. As shown in FIG. 2, the rod-shaped operating lever 3 has a slightly elongated rod shape, and a square window 4 is formed on the right side of the center thereof, and the lever is restored via a stopper plate 5 within this square window. A spring 6 is provided. on the other hand,
A ball hole 7 and slit windows 8, 8 are provided on the left side of the operating lever, and an action ball 9 and an action spring 10 are loaded into the ball hole 7, and an insulating plate 11 is installed at the rear of the ball hole 7. A movable contact 12 having a three-point protrusion is fitted therebetween using the slit windows 8, 8 so as not to slip out. Furthermore, shoulders 13 and 14 are formed on the left and right rear surfaces of the operating lever to restrict the left and right movement of the lever. 15 in the figure is an action plate, and the operating lever controls the travel position and engine stop switch.
It has holes 16 and 17 into which the action ball 9 is fitted in the OFF position, and this action plate is appropriately fixed to the switch case 2. Also, 18 in the figure
is a fixed contact plate, and the movable contact 1 is mounted on the front side of this plate.
Fixed contacts a, b, and c, which control the functions of starting, running, and stopping the engine, are arranged in series at positions corresponding to switch case 2, and this fixed contact plate itself is fixed to switch case 2. FIG. 3 shows a central longitudinal cross-sectional plan view of the assembled state of the members shown in FIG. 2. The state shown in FIG. 3 is a running state, that is, a state in which the engine stop switch is not turned off.

The functions of the starting switch according to the present invention will be explained below.

In Fig. 1, when the operating lever 3 is in the position indicated by the solid line, the three protrusions of the movable contact 12 are each in the + mark position, connecting the fixed contacts b and c, and the movable contact 12 is in a state where it can run. be. When the vehicle stops at this position and the operating lever is pushed to the right, the action ball is activated at the position indicated by the dashed line and the vehicle is stopped. In this position, the three-point protrusion of the movable contact is in the position marked with *.
Two of the three protrusions on the movable contact have come off from the fixed contacts b and c that were connected at the + position, and only one point is now in contact with the fixed contact c, so the circuit is open. The engine will be stopped. However, in the present invention, the start switch is structured to push the operation lever 3 to the left, so after the engine is released from the stopped state and the engine is running, the start switch must be pushed to the position shown by the two-dot chain line to start the engine. I will do it. In this state, the engine is started when the three-point protrusion of the movable contact is at the mark position. In this starting position, the operating lever does not stop, but due to the action of the restoring spring 6, when the lever is released, it automatically returns to the central running position. FIG. 4 is a diagrammatic representation of the functional state of this switch. In addition, in the above embodiment, a three-point protrusion type movable contact was explained in consideration of stability, but this is a two-point protrusion type.
Needless to say, a point protrusion type may also be used.

In this invention, as mentioned above, the engine is stopped by pushing one bar-shaped operating lever in one direction, and the engine is started by pushing the same operating lever in the opposite direction. It is inevitable that you will no longer turn on the start switch while it is off. Therefore, there is no need to leave the engine stop switch in the OFF position and operate the start switch as in the past, causing the engine to not start and twisting one's neck. Even when operating while wearing gloves, the only operation required is a push button, making it extremely easy to use.

Furthermore, it is structurally simple, requiring only one switch case, and wiring can be largely omitted, which helps reduce costs and has high industrial applicability.
