Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pedal device for automobiles and the like.

[0002]

2. Description of the Related Art Various pedal devices have been proposed in order to make a conventional automobile driving system safe. In the first conventional example, for example, a conventional horizontal axis is supported, and an accelerator pedal that has been vertically depressed is supported by the vertical axis to form a lateral push operation mechanism. This is effective in preventing the accelerator pedal from being depressed due to a malfunction.

Further, as a second conventional example, there is proposed a brake pedal provided with a joint which can be horizontally rotated so that the accelerator pedal can be operated by pushing the brake pedal sideways while placing the operating foot on the brake pedal. Here, the brake pedal and accelerator can be operated with a single brake pedal, which was effective in preventing malfunction.

Further, as a third conventional example, a return roller with a one-way cam is attached to a brake pedal,
It is also proposed that if the brake is depressed as it is, the brake is operated and if the foot is swung to the right, the accelerator is operated. This makes it possible to reduce the loss time for shifting from the accelerator device to the brake device. In this configuration, since the foot is placed on the brake pedal during the accelerator operation, the toe support is maintained by the magnet and the ball system to prevent half-braking.

Further, as a fourth conventional example, in an automatic vehicle, a half-brake caused by preventing a runaway accident due to a malfunction of a brake pedal and an accelerator pedal and leaving a foot on the pedal, In order to prevent a half-clutch, a so-called free pedal has been proposed in which the toe support force is obtained by the balance of the depression of the heel.

[0006]

By the way, in the conventional pedal device as described above, in the first case, there is a possibility that it may be an obstacle in the unlikely event that the guide member for supporting the operating foot is used.

In the second case, the brake arm is machined, which requires extra manufacturing work, and the accelerator pedal cannot be operated while the brake pedal is depressed.

In the third case, it is necessary to slightly suppress the stability during the accelerator operation and the excessive reaction of the brake operation.

In the fourth case, since the bottom of the foot comes into contact with the roller during the accelerator operation, there has been a desire to support it on a flat surface. In addition, the lateral push method has a high safety, but there is a drawback that the accelerator cannot be operated with a feeling of stepping. Further, there is a difficulty in delicate operation feeling due to the balance between the shoe bottom and the roller contact effect.

SUMMARY OF THE INVENTION An object of the present invention is to provide a pedal device which has been made in view of the above-mentioned drawbacks and which can realize stability of accelerator operation and agility from accelerator operation to brake operation.
