Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile pedal mechanism, and more particularly to a pedal mechanism in consideration of holding a toe. In other words, a mechanism that allows the toe support force and heel front support force to be adjusted or maintained by the driver's intention by using the fulcrum at the bottom of the pedal as the driver's intention
Is.

[0002]

2. Description of the Related Art Among conventional pedals provided in a driver's seat of a vehicle, there has been proposed a pedal mechanism capable of operating an accelerator pedal with a foot on a brake pedal in order to improve operability. There is.

[0003]

By the way, in such a conventional pedal mechanism, it is necessary to always keep the foot on the brake pedal or the clutch pedal. Therefore, unless the brake pedal or the clutch pedal is held at a predetermined position by some method, a half brake or a half clutch will be formed, and the brake lining or the clutch plate will be damaged. Existed. Also, when switching from a vehicle with a clutch to an automatic vehicle, there were problems such as lost legs. In other words, the conventional clutch pedal is operated by changing the pedal, but raising the operating foot and stepping on the pedal causes the weight balance to be lost when stability is required most. Further, the lack of supporting force during the operation of the accelerator pedal is apt to cause a semi-brake, and it has been desired to develop a pedal that compensates for this. Also, due to the structure of the brake pedal, the soles of the feet come into contact with each other while rolling, making it slippery on rainy days.

The object of the present invention was made in view of the above-mentioned drawbacks. Even if the user keeps his / her foot on the pedal, he / she depresses against his / her will to make a half-clutch or half-bracket.
It is to provide a pedal mechanism (free pedal) that does not cause excessive depression.

[0005]

A pedal mechanism according to the present invention has a plate-shaped brake pedal, one end of which is in contact with a floor surface and the other end of which is supported by a brake arm. It is composed of accelerator pedals arranged substantially parallel to each other. Further, in the pedal mechanism operated by the movement of the foot, one end is in contact with the floor surface, the other end has a plate-shaped brake pedal supported by a brake arm,
A brake arm that supports the plate-shaped brake pedal and an accelerator pedal that is arranged substantially parallel to the upper surface of the plate-shaped brake pedal may be used. Further, in the pedal mechanism operated by the movement of the foot, a clutch arm that supports the clutch pedal is provided, and one end is in contact with the floor surface and the other end is provided with a plate clutch pedal supported by the clutch arm. Is a pedal mechanism (free pedal).

[0006]

As described above, in the pedal mechanism according to the present invention, the accelerator pedal can be operated by twisting the operating foot in the lateral direction with the heel as a fulcrum by the accelerator pedal pressing mechanism, so that it is not necessary to step on the brake pedal. .. In other words, it is possible to make a parallel translation in the lateral direction with the heel as the axis, and to make the knee open outward to control the lateral pressing force, so that a comfortable posture for long-time driving can be maintained. Further, when the foot is placed on the brake pedal, the end of the foot on the little finger portion is in contact with the accelerator pedal, so that the stepping time can be remarkably shortened. Further, at the initial stage of the runaway of the vehicle, the legs that are bulged by the action of the guide roller are guided to the plate-shaped brake pedal, and the runaway can be easily prevented. Further, when used as a clutch pedal or an accelerator pedal, even if the foot is left on, the half clutch or the half brake does not occur.

[0007]

An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a plan view showing a pedal mechanism that is an embodiment of the present invention. Here, the plate-shaped brake pedal 10, which is a pedal mechanism, is supported by an arm 11. The arm 11 is rotatably supported by a fulcrum 12, and is biased in the direction of arrow C by a spring (not shown). The tip of the arm 11 has a rising portion 13, and the rising portion 13 pivotally supports the plate brake pedal 10 from below. The plate-shaped brake pedal 10 has a substantially rectangular shape,
The lower end of the upper surface on which the foot is placed is formed longer than the rear surface side. That is, the hemispherical portion 14 is formed at the lower end of the plate brake pedal 10. A guide roller 16 and a ratchet 17 that prevents the guide roller 16 from rotating in the reverse direction are provided on the upper right end of the plate brake pedal 10. The guide roller 16 is set to rotate by the ratchet 17 only in the arrow D direction. The same applies when a one-way clutch is used instead of the ratchet 15.

The accelerator pedal 20 is rotatably supported in a horizontal direction (direction of arrow E) by a support tool 21, and is urged by a spring (not shown) to return to its original position. A throttle rod 22 connected to a throttle portion (not shown) is connected to a tip end portion of the accelerator pedal 20. Further, the accelerator pedal 20 is arranged substantially parallel to the upper surface of the plate brake pedal 10.

Next, a method of using the pedal mechanism configured as described above will be described. First, when operating the accelerator pedal, attach the heel of the shoe to the floor (point B) and turn the base of the little finger to the right. At this time, the bottom surface of the foot is in contact with the derivative of the plate-shaped brake pedal 10, the roller, or the protrusion. Therefore, the foot can be smoothly moved. Further, as shown in FIG. 1, when operating the plate brake pedal 10, the user releases the accelerator pedal 20 and then presses the plate brake pedal 10 downward. At this time, the guide roller 16 is not released from the accelerator pedal 20.
Can be easily performed by the action of. In other words, due to the horizontal axis motion of the brake and the vertical axis motion of the accelerator, both the operation of the operating foot is changed to the vertical operation of the brake and the lateral operation of the accelerator is changed to the vertical operation of the brake, thereby increasing the agility of the operation.

FIG. 4 is a side view of an essential part of a plate-shaped brake pedal portion showing another embodiment, and FIG. 5 is a plan view of a pedal mechanism. In both figures, the pedal mechanism has a plate-shaped brake pedal 10 whose one end is in contact with the floor surface via a hemispherical portion 24 and whose other end is supported by a brake arm 11, and a brake arm which supports the plate-shaped brake pedal 10. 11 and an accelerator pedal 20 arranged substantially parallel to the upper surface of the plate-shaped brake pedal 10. The guide roller 16, ratchet 17, support 21, throttle rod 22, etc.
The description is omitted because it is similar to the first embodiment.

With the above construction, when the foot is placed on the brake pedal 10, the elevation angle can be easily adjusted, and the driver can operate the vehicle at the optimum elevation angle position. In addition, fatigue does not occur even when driving for a long time. Also, urban areas, rough terrain, mountainous areas,
There is little feeling of fatigue when driving on highways. Also,
The hemisphere portion 24 allows the accelerator pedal to be reliably released,
There is also peace of mind.

FIG. 6 is a side view showing another embodiment of the present invention. In the figure, the parts other than the plate-shaped brake pedal 30 are the same as those of the other embodiments, and therefore their explanations are omitted. Here, the plate brake pedal 30 is rotatably supported by an arm (not shown). Further, the lower end of the plate-shaped brake pedal 30 is formed in a semicircular shape, and the curved surface 30a is in contact with the floor surface. In the case of the above configuration, the plate brake pedal can freely change the elevation angle or position of the brake pedal by slidingly contacting the floor and changing the height of the floor by laying something under the seat. You can choose to. That is, the lower end portion 30a of the pedal,
While supporting at two points of the heel Y, the pedal moves about the center of rotation X, but the movement is restricted by the floor surface and fixed near the heel so as to step on the floor surface. Hold. The balance can be released freely by one's own intention, and the user can perform a smooth pedaling action by depressing the pedal with the thumb.

Next, the case where the pedal mechanism of the present invention is applied to a clutch pedal (free pedal) will be described. As shown in FIG. 7, in the pedal mechanism operated by the movement of the foot, the clutch arm 26 that supports the clutch pedal is used.
And a plate-like clutch pedal 25, one end of which contacts the floor surface 27 and the other end of which is supported by a clutch arm.
With this configuration, the clutch pedal can support the foot because the holding force can be obtained by pressing with the heel. In other words, since the floor surface has no obstacle in front of the heel, the action can be taken smoothly and quickly. Also, attach the heel directly to the floor to stabilize it during operation. In addition, the contact part between the pedal and the floor is the heel and the contact part on the floor with two-point support.
The bottom of the triangle with the brake pedal rotation support as the apex is the base and is stable.

Here, since the free pedal inherits the toe support force from the heel by the pedal plate, one plate shape is optimal. In addition, the pedal related to the heel does not use a spring or the like that acts as a counter-pressing pressure, and the balance between the toe and the heel can be adjusted by one's own will. That is,
If there is an obstacle in the front, there is a possibility that the behavior will be obstructed immediately. The pedal and the arm are pivotally supported, and the heel directly contacts the floor surface with one plate, and the lower vicinity of the pedal is not bound or fixed to the front wall or the like.
In addition, it is assumed that the left foot operates the clutch pedal and the right foot operates the brake and the accelerator pedal.

FIG. 8 shows another embodiment of the present invention, in which the plate brake pedal 40 is supported by an arm member 41. At the lower end of the back of the plate brake pedal 40,
A fulcrum portion 42 having a hemispherical cross section is provided so as to project, and the fulcrum portion 42 is in contact with the floor surface. A vertical depressing mechanism 43 is arranged at the right end of the plate brake pedal 40.
The vertical depressing mechanism 43 is composed of a step plate 45, which is biased by a spring 44 so as to be able to rotate half-turned to the right end of the plate brake pedal 40, a guide roller 46, and the like. A hemispherical portion 45a is formed. On the other hand, the accelerator pedal 47 is supported so as to rotate about a shaft 48 substantially in parallel with the floor surface and to rotate about a shaft 49 vertically to the floor surface. Therefore, the plate-shaped brake pedal 4
Even if 0 is depressed, the accelerator pedal 47 follows the brake pedal 40 and descends. Further, if the tread slab 45 is stepped vertically, the hemispherical portion 45a turns the accelerator pedal 47 laterally.

Next, the operation of the pedal mechanism configured as described above will be described. First, a foot is put on the brake pedal 40, and a holding force is generated by the heel and the fulcrum portion 42.
Thereby, the right foot is held and can be used as a footrest. Further, when the brake pedal is depressed, if a force is applied to the toe of the right foot, the plate brake pedal 40 is pressed and the braking operation is performed. Further, when the accelerator is operated, the vertical depressing mechanism 43 provided on a part of the plate brake pedal 40 is vertically depressed. Then, the step pedestal 45 is rotated to rotate the accelerator pedal 47 laterally. When the accelerator pedal 47 is turned sideways, fuel is supplied to the engine (not shown). Thus, in this embodiment,
The accelerator operation can be performed by stepping on the vertical pedal mechanism 43 vertically. Therefore, even a person who has become accustomed to the conventional vertical-pedal accelerator pedal can easily use the return pedal and can easily use the accelerator pedal.

On the other hand, the accelerator pedal 47 is arranged so as to always follow the upper surface of the plate brake pedal 40 by being biased by a spring. Therefore, the plate-shaped brake pedal 4
The accelerator pedal can be operated even when 0 is depressed. As a result, it is possible to prevent a runaway accident when the engine is started, on a slope, or when the vehicle normally starts.

FIG. 11 is a plan view showing another embodiment of the present invention. Here, the accelerator pedal 50 has a substantially rectangular shape, and an extension portion 51 extending leftward is provided at a lower end portion.
Are formed. The extended portion 51 has a brake pedal 52.
Since it extends to the vicinity of just below and can be pressed by the heel without operating the brake pedal, excessive depression of the accelerator pedal and erroneous operation can be prevented. The cross section of the extended portion 51 is
Various shapes such as a round shape, an oval shape, and an oval shape can be applied.

As described above, the free pedal configured as described above allows the user to voluntarily adjust the balance as necessary during the process of operation while maintaining the balance between the heel force point and the toe force point. This is to adjust the accelerator while supporting the body weight against the over-pressing pressure. That is, in the case of the accelerator pedal, since the operator's foot is placed on the pedal for driving, there is always a possibility of over-pressing due to inertial force and weight. In the present embodiment, the front position of the heel is the same, and a momentary space during the transition from the brake pedal to the accelerator pedal is eliminated, so that the position confirmation, which conventionally relies on intuition, can be facilitated.
That is, since the extended portion 51 is pressed by the heel before the operation foot reaches the accelerator pedal, the balance is easily maintained. This allows the accelerator pedal, which has been unintentionally depressed, to be operated accurately. It is especially effective on rough roads, mountainous roads, and slopes.

[0020]

As described above in detail, the pedal mechanism of the present invention is a pedal mechanism which is operated by the operation of the foot, and is a plate-like brake in which one end contacts the floor surface and the other end is supported by the brake arm. Since the pedal and the accelerator pedal are arranged substantially parallel to the upper surface of the plate-shaped brake pedal, the plate-shaped brake pedal can support the foot, and the driver does not feel tired even after long-time driving. That is,
The toe can be held by the balance between the heel and the pedal plate. On the other hand, when stepping on the pedal, it is possible to easily step on it by releasing the force and putting force on the big toe. Further, since the position of the brake pedal can be adjusted according to the driver, it is possible to drive at the optimum position and angle. Further, when the lower end of the plate-shaped brake pedal is a roller, the elevation angle position of the plate-shaped brake pedal can be easily changed. Furthermore, it can be operated in a comfortable position depending on the external rotation angle of the foot. That is, the angle of the foot in the direction of external rotation is within the range of motion or rest, and the supporting force and operability are stable. According to the second aspect, the elevation angle position of the pedal can be easily moved. In the case of the structure according to the third aspect, it can be applied to the clutch pedal and can support the foot. In the case of the construction as set forth in claim 4, since the extension portion does not obstruct the course of the brake operation, it serves as the front supporting force of the heel when the brake pedal is operated. In addition, the heel support of the brake and accelerator are integrated, and the pedal toe support force is exerted before touching the accelerator pedal action point without relying on intuition, which is safe. Further, since the supporting force is obtained by stepping on the extended portion, which is a part of the plate-shaped brake pedal, stable operation can be performed and the fatigue level is reduced.
