Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a turn signal warning device suitable for implementation on a motorcycle.

Similar to automobiles, motorcycles are also equipped with warning devices that notify the driver that the turn signal is activated.

This is to prevent a turn signal that is activated to make a left or right turn from causing a nuisance to other vehicles if it continues to operate even after the left or right turn has been completed.

By the way, in the current turn signal warning system used for motorcycles, the volume of the warning buzzer is constant, so if it is too loud, it will be noisy when stopping at intersections etc., which will cause dissatisfaction with the driver, and if it is too low, the warning buzzer will not sound would lose its meaning.

That is, when the turn signal is turned back on, it is when turning a corner and entering an acceleration state, so the engine noise becomes louder and the sound of the warning buzzer becomes harder to hear.

In the past, in order to solve this problem, some turn indicators were equipped with an automatic canceling device.

According to the automatic canceling device, when the motorcycle completes a left or right turn, the turn signal itself automatically returns to the inactive state, so that the above-mentioned problem does not occur.

However, this circuit, after activating the turn signal,
Since the turn signal is automatically turned off after a certain distance has been traveled or a certain period of time has elapsed, the mechanism and electrical circuits are complicated and expensive.

The present invention has been made to solve these problems and drawbacks.

An embodiment of the present invention will be described with reference to FIGS. 1 and 2. Reference numeral 1 denotes a throttle grip, which is rotatably supported along with a grip tube 2 to an upper holder 3 and a lower holder 4. be.

The upper holder 3 and the lower holder 4 are fixed to a nozzle pipe (not shown) located on the left side of FIG. 1 with bolts.

An accelerator wire attachment screw 5 is provided in a part of the lower holder 4, to which one end of an accelerator wire (not shown) is attached.

The other end of the accelerator wire is connected to the throttle opening/closing mechanism of the carburetor.

As shown in FIG. 1, the grip tube 2 is provided with a notch 6 having a circular cross section, so that one end of the core wire of the accelerator wire, one end of which is attached to the accelerator wire mounting screw 5, is engaged. It has become.

With this mechanism, when the throttle grip 1 is rotated, the core wire of the accelerator wire is pulled to open and close the throttle valve of the carburetor.

A switch 7 serving as current control means is provided inside the lower holder 4, and its actuator 8 faces a stopper portion 9 of the grip tube 2.

The positional relationship between the actuator 8 and the stopper part 9 is as follows:
The actuator 8 is pushed when the throttle grip 1 is returned to its original position (see the arrow in Fig. 3) to bring the engine into the idling state.

In this embodiment, the switch 7 is of a type that opens when the actuator 8 is pressed, and is connected as shown in FIG.

In this figure, 10 is a battery, the negative electrode of which is grounded (grounded to the vehicle body, the same applies hereinafter).

The positive terminal of the battery 10 is connected to the ignition switch 11
and is connected to a movable contact 14 of a blinker switch 13 via a blinker relay 12.

The turn signal switch 13 has two fixed contacts 15 and 16.
are provided, and the movable contact 14 comes into contact with one of these during operation (when turning left or right).

When inactive, the movable contact 14 remains in a neutral state as shown.

An alarm buzzer 17 and the aforementioned switch 7 are connected in series between the fixed contacts 15 and 16.

Further, blinker lamps 18, 19 and blinker lamps 20, 21 are connected in parallel thereto.

The connection point between the blinker lamps 18 and 19 and the connection point between the blinker lamps 20 and 21 are grounded.

When the fixed contact 15 of the turn signal switch 13 is used as a left turn contact and the fixed contact 16 is used as a right turn contact, the turn signal lamp 1
8.20 is a left turn lamp, turn signal lamp 19.2
Number 1 is the right turn ramp.

In this device configured in this way, the blinker
When the movable contact 14 of the switch 13 is brought into contact with the fixed contact 15 or 16 to blink the blinker lamp 18, 20 or the blinker lamp 19°21, the alarm buzzer 17 is activated if the switch 7 is closed. I will do it.

As mentioned above, the switch 7 opens when the throttle grip 1 is returned to put the engine in the idling state, and is closed in other states, so it does not operate when stopped at an intersection, etc., and does not operate when driving. I will do it.

What is shown in FIG. 7 is another embodiment of the present invention.

In this case, a resistor 22 is connected in parallel to the switch 7 to reduce the current flowing to the alarm buzzer 17 when the switch 7 is opened.

This allows the warning buzzer to sound when stopped at an intersection etc.
170 The volume of the emitted sound can be lowered.

The embodiment shown in FIG. 4 is an embodiment in which the same operations as those in FIGS. 1 to 3 are carried out on the carburetor side.

To explain this, 23 is the main body of the carburetor, and a butterfly shaft 24 rotatably protrudes from the main body 23, and the rotation of the butterfly 25 is transmitted to a throttle valve (not shown) in the main body 23. It is supposed to be done.

The butterfly 25 has a butterfly holder 26 and a cover 2.
7, and is rotated by an accelerator wire attached to accelerator wire attachment screws 28 and 29 provided on the butterfly holder 26.

30.31 is Patsukin.

Butterfly holder 26 accelerator wire mounting screw 2
A mounting screw 32 of the push button type switch 7 is screwed into the portion between 8 and 29.

The actuator 8 of the switch 7 faces the stopper 33 of the butterfly 25, and is opened when the engine is idling with the throttle valve closed.

34 is a lead wire, and 35 is a switch waterproof cover.

In this embodiment as well, the connection circuit of the switch 7 is exactly the same as that described above.

Next, another embodiment of the present invention will be described with reference to FIG.

In this case, a variable resistor 37 serving as a current control means is provided inside a handle pipe 36 provided inside the throttle grip 1, and a shaft 38 of this variable resistor 3T is connected to a cap fitted to the throttle grip 1. 390 holes 40
The resistance value of the variable resistor 37 changes when the throttle grip 1 is rotated.

An unevenness 41 is formed on the outer periphery of the cap 39 to prevent it from slipping from the throttle grip 1.

42 is a lead wire.

In this embodiment, by connecting the variable resistor 37 as shown in FIG. 8, the volume of the alarm buzzer 17 can be changed in accordance with the opening degree of the throttle valve.

Note that a rotary switch 7 may be provided in place of the variable resistor 37, and this switch 7 may be connected as shown in FIG. 6 or 7.

Since the present invention is simple as described above, it has the advantage of improving the function of warning for forgetting to turn off the direction indicator, and eliminating the drawbacks of the conventional ones that were unpopular with users.

In addition, the alarm buzzer can be realized with a simple structure of connecting the current control means linked to the throttle valve in series and connecting it between the two fixed contacts of the blinker switch.
In addition to being able to be applied to all types of motorcycles, it also has the advantage of being able to be additionally installed on existing motorcycles.
