Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art As a conventional accelerator device, for example,
There is one as shown in FIG. In this accelerator device, the heel of the foot is placed on the vehicle floor, the part other than the heel is placed on the accelerator pedal 1, and the accelerator pedal 1 is depressed in the vehicle floor direction to open / close the throttle valve 3 via the link mechanism 2. It is a thing.

[0003]

However, in such a conventional accelerator device, for example, when the vehicle is not accelerating suddenly,
In order to keep the vehicle speed constant, it is necessary to have a force to lift the foot off the floor of the vehicle, and there is a problem that the legs and the like become very tired to maintain this force when traveling for a long time.
The present invention has been made focusing on such conventional problems, the legs and the like do not get tired even when traveling for a long time,
An object is to provide an accelerator device that can be easily driven.

[0004]

SUMMARY OF THE INVENTION An accelerator device for achieving the above object is a slide portion slidably provided in a front-rear direction of a vehicle body, and a driver's foot is placed on the slide portion of the slide portion. A foot rest portion provided on the slide portion so as to move together, an urging means for urging the slide portion rearward, and an interlocking means for opening and closing the throttle valve according to the slide amount of the slide portion. It is characterized by having. Here, it is preferable that the foot rest has a roller having a rotation axis oriented in a direction substantially parallel to the vehicle floor. Further, the interlocking means may be a wire, a link mechanism, a hydraulic mechanism, or an electric one.

[0005]

In operation, the foot is placed on the foot rest, and the foot rest and the slide portion are moved in the front-back direction according to the increase / decrease in speed. The throttle valve opens and closes according to this amount of movement,
The vehicle speed changes. The weight of the foot placed on the foot rest is supported by the foot rest and the slide. For this reason,
When driving, the force to support the weight of the foot is unnecessary. As a necessary force, only a slight force is required to push the slide portion biased rearward by the biasing means forward. Therefore, during driving, the force for supporting the weight of the foot is unnecessary, and since only a slight force for pushing the slide portion forward is required, the legs and the like can be comfortably driven without being tired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the accelerator device according to the present invention will be described below with reference to FIGS. As shown in FIG. 1, the accelerator device of the present embodiment is mounted on a base portion 10 fixed to a vehicle floor F and a base portion 10 that is substantially parallel to the vehicle floor F and can slide in the front-rear direction. The slide portion 20, the roller 30 on which the foot rests, and the link mechanism 4 that opens and closes the throttle valve 49 according to the movement of the slide portion 20.
It has 0 and.

As shown in FIG. 3, the slide portion 20 has a bottom plate 21 and side plates 22 and 22, and has a groove shape. A roller 30 is provided on the side plates 22 and 22.
A rotary shaft 31 for rotatably supporting the vehicle is provided substantially parallel to the vehicle floor F, and the roller 30 is provided there. Base part 10 to which the slide part 20 is attached
Is, as shown in FIG. 3, the substrate 11 and the side plates 12, 12.
And has a groove shape like the slide portion 20. The side plates 12 and 12 are provided such that the distance between the side plates 12 and 12 becomes narrower toward the upper side so that the slide portion 20 does not come out upward. This side plate 12,
The guide 12 has guide shoes 13, 13 for restricting the movement of the slide portion 20 in the left-right direction and the vertical direction with respect to the driver. Further, the board 11 is provided with rails 14 and 14 in a direction that is a front-back direction with respect to the driver, that is, a direction in which the slide portion 20 slides. Instead of the guide shoes 13, 13, rails may be provided there.

As shown in FIGS. 1 and 2, a crank lever 41 is rotatably provided at the front end of the base 10 to support the support shaft 4.
It is provided through 2. One end of a connecting rod 43 is attached to the front end of the slide portion 20, and the other end is connected to one end of the crank lever 41. The other end of the crank lever 41 is connected to the wire 44 connected to the throttle valve 49. The support shaft 42 of the crank lever 41 is provided with a coil spring 45 for biasing the slide portion 20 connected via a connecting rod 43 rearward. The lengths of both arms of the crank lever 41 are such that when the slide portion 20 is located at the rear end portion of the base portion 10, the throttle valve 49 is in an idling state and the slide portion 20 has a length of the base portion 10. The throttle valve 49 is set to be fully open when it is located at the front end. The link mechanism 40 includes a connecting rod 43, a crank lever 41, a support shaft 42, and a wire 4.
4 and 4.

Next, the operation of this embodiment will be described.
The driver places his foot on the roller 30 and pushes it forward when he wants to accelerate. The roller 30 is pushed forward while rotating in the reverse direction, and when the slide portion 20 slides forward, the link mechanism 40 operates accordingly and the throttle valve is opened. When you want to maintain the speed, the roller 30
Maintain its front-back position. At this time, the force required by the driver is a force H that pushes the roller 30 forward, that is, the spring 4 that biases the slide portion 20 backward, as shown in FIG.
Only the power to resist 5. In the direction perpendicular to the vehicle floor F, the force for maintaining the foot, that is, the force V for supporting the own weight of the foot is applied to the roller 30, the slide portion 20, and the base portion 10 to support the own weight of the foot. The force V becomes unnecessary. By the way, the force H for pushing the roller 30 forward may be generally much smaller than the force V for supporting the weight of the foot. Therefore, only the force H that pushes the roller 30 forward is required during driving, including during acceleration, and the legs and the like do not become tired even during long-time running.

Further, in a normal posture, the direction of the force applied from the foot to the roller 30 is substantially parallel to the direction of the lower leg bone, and is different from the direction in which the slide portion 20 slides, so that an erroneous operation of the accelerator can be prevented. Therefore, if the present invention is applied to an automatic vehicle or the like that may suddenly start due to an erroneous operation of the accelerator, the safety can be improved.

The portion on which the foot is placed is basically the roller 30.
However, when accelerating and decelerating, when the roller is depressed with the foot so that the toe is lowered, the angle formed between the vehicle floor F and the back of the foot is changed.
Is preferred. In addition, in the present embodiment, the accelerator device is provided on the substantially horizontal vehicle floor F. However, in consideration of the expansion and contraction of the legs, the angle of the back of the foot, and the like, the vehicle is placed on the vehicle floor F where the front is higher. It is preferable to provide. In addition, in the present embodiment, the slide portion 20 is slid linearly, but the slide portion 2 slides as it slides toward the front end side.
You may make it slide in an arc shape so that 0 may become high. Further, in this embodiment, in order to correspond to the opening / closing of the throttle valve 49 with the movement of the slide portion 20, the link mechanism 4
Although 0 is provided, it goes without saying that this may be performed by a hydraulic mechanism or electrically.

[0012]

According to the present invention, since the force for supporting the weight of the foot is unnecessary, the legs are hardly tired and the driver can drive easily.
