Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brake device for safely stopping an automobile or the like.

[0002]

2. Description of the Related Art Conventionally, to stop an automobile or the like, it is necessary to take a foot off the accelerator petal and step on a brake petal.

[0003]

Conventionally, the stop of an automobile or the like is performed by stepping on the brake petal by releasing the foot from the accelerator petal. However, in an emergency, the pedal is released from the accelerator petal. There was a case that he accidentally stepped on the accelerator pedal due to emotional upset, nervousness, illusion, and innocence, leading to a serious accident.

An object of the present invention is to provide a brake device for safely and rapidly stopping an automobile or the like even in an emergency.

[0005]

To achieve the above object, in the brake device of the present invention, when the accelerator pedal is depressed beyond the operating range as the accelerator petal, the connection between the accelerator petal and the carburetor is released. Then
Further, by interlocking with the brake device, the automobile or the like can be safely stopped in any case.

[0006]

[Effect] When you should instantly press the brakes in an emergency etc., even if you suddenly step on the accelerator pedal due to your feelings etc., it will work as an accelerator up to the maximum position as an accelerator petal, but during that time It is a very short time, and there is no problem considering the start-up time of the engine. Immediately after passing there, the carburetor becomes idling and the engine brakes.
Next, the accelerator petal produces the same effect as stepping on the brake petal in conjunction with the brake, stopping the automobile or the like. Also, when I noticed that I was stepping on the accelerator petal here, even if I stepped on the brake petal, even in an automatic vehicle, the engine was idling and the forward force was small, so there was no problem with the stopping effect. When the emergency situation is over and the vehicle is in a state where the accelerator pedal is still stepped on when starting, by releasing the foot once from the accelerator petal and making it idle, the accelerator petal is connected to the carburetor again and becomes the normal state. You can start by stepping on. When stepping on the brake petal again, the accelerator petal has already returned to the idling state, and the connection with the carburetor has ended, and the vehicle is in a normal state.Therefore, simply step on the accelerator petal to start the vehicle. Can be done.

In a two-petal automatic vehicle, the braking device of the present invention can stop the vehicle by stepping on either petal, so that the effect is particularly great. In addition, considering emergency braking in an emergency, it will bring even greater effect to a vehicle equipped with an anti-lock brake.

[0014]

Since the present invention is constructed as described above, the effects can be obtained by the following operations.

In normal operation, the accelerator petal 1
On the brake arm 5 when releasing the brake petal 4,
The normal operation range is until the adjustment part 2 of the accelerator pedal contacts. When the accelerator pedal 1 is released, the accelerator wire 23 is in the most pushed out state, and the movable plate 17 is pulled by the tension of the spring 22. Prior to this, the ring-shaped leaf spring is passed through the connecting hole 13 and the movable plate 17 of the movable plate 16 which is pulled by the spring 14 and holds the operating shaft of the carburetor in the idling state by the movable portion 10. Connecting pin 1 held so as to stick out
8, the connecting pin 18 is projected into the connecting hole 13, and the movable plate 16 and the movable plate 17 are connected. As a result, the accelerator pedal and the carburetor are directly connected, and normal accelerator operation can be performed.

When the brake petal 4 is stepped on, the brake operation unit 9 can be pushed to perform a brake operation, but the brake arm 5 moves away from the accelerator petal adjustment unit 2 so that it does not affect others. .

The normal operation of the accelerator petal 1 is carried out until the accelerator petal adjusting portion 2 comes into contact with the brake arm 5 when the brake petal 4 is released, when it is depressed,
After that, the brake arm 5 is moved by the accelerator petal 1 at the same time, and it becomes heavy because it is in an interlocking state. Since this position can be sufficiently confirmed, the normal operation of the accelerator petal 1 does not cause further depression.

In normal operation of the accelerator pedal 1, the accelerator wire 23 is depressed by depressing the accelerator pedal 1.
Is pulled, whereby the movable plate 17 rotates in the direction in which the spring 22 extends. Since the movable plate 16 is connected to the movable plate 17 by the connecting pin 18, at the same time the spring 14
Rotate in the direction to extend and activate the carburetor.

The movable plate 16 and the movable plate 17, which are connected to each other, rotate when the accelerator pedal 1 is depressed.
The connecting pin 18 at 7 also rotates and approaches the fixed pawl 21. This relationship is such that when the accelerator pedal is pushed to the full extent of the normal operating range, that is, when the accelerator pedal adjusting portion 2 and the brake arm 5 come into contact with each other, the tip B of the fixed pawl 21 causes the gap C of the connecting pin 18 to come into contact. Is set to stop just before entering and expanding the gap C. This adjustment can be accurately made by adjusting the length of the accelerator wire and the adjusting portion 2 of the accelerator petal.

When the accelerator pedal 1 is further stepped on in an emergency or the like, since the adjusting portion 2 of the accelerator petal and the brake arm 5 are in contact with each other, the brake petal is also interlocked and the brake device starts to operate.

Since there is some play at the beginning of interlocking with the brake device, the tip A of the fixed pawl 21 at this point is
Enter into the gap B of the connecting pin 18 and push the gap B wide. As a result, the portion where the connecting pin 18 projects toward the movable plate 16 is pulled through the hole of the movable plate 17, and the connection between the movable plate 16 and the movable plate 17 is released.

When the connection between the movable plate 16 and the movable plate 17 is released, the movable plate 16 is pulled by the spring 14 and the movable portion 10 immediately brings the carburetor into the same idling state as when the accelerator petal 1 is released. As a result, the engine is in the brake state, which assists in stopping the vehicle.

The accelerator petal 1 which has already been interlocked with the brake device at the previous time point and the connection between the movable plate 16 and the movable plate 17 has been released, interlocks with the brake petal and operates only as a brake device. Therefore, by further depressing this, the automobile or the like can be stopped rapidly.

When the emergency situation is over, the accelerator plate 1 is released to move the movable plate 17 by the spring 22.
Returns to the initial idling state. This allows
The position of the connecting pin 13 of the movable plate 17, which was previously released from the movable plate 17 and returned to the idling state, matches the position of the connecting pin 18 of the movable plate 17, and the plate spring 19 connects the connecting pin 18 to each other. Goes into the connecting hole 13 of the movable plate 16, the movable plate 16 and the movable plate 17 are connected again, and the accelerator pedal is in a normal state.

As described above, according to the brake device of the present invention, the operations after the item 0020 are performed in a very short time. For this reason, it is possible to safely stop an automobile in a very short time compared to stepping on the brake petal after releasing the foot from the conventional accelerator petal.
In particular, the great effect of preventing a large accident due to a mistake in pedaling in a case of emergency can be obtained at low cost.

Further, by using the brake device of the present invention for an automatic vehicle and a vehicle equipped with an anti-lock brake, by not stepping on a petal in an emergency etc. It is possible to obtain a safe emergency stop device.
