Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for an automobile, which prevents a danger associated with the ease of driving operation of the automobile and stops the automobile in a short time by stepping on a brake pedal quickly and surely. It is an object.

[0002]

2. Description of the Related Art An automobile uses a gasoline engine or other engine as a drive source and supports a person who operates with three or more wheels, and a vehicle body on which the engine and other various devices involved in stopping traveling are supported. The power from the car is transmitted to move the car holiday. A device that turns power on and off is called a clutch, and a clutch pedal (a pedal is a footboard) that operates this with a foot, an accelerator pedal that supplies gasoline, which is fuel to the engine, and a brake that uses both foot force and hydraulic pressure. There are brake pedals to operate. In a right-hand drive vehicle, these pedals are usually operated by pressing the accelerator pedal and brake pedal with the right foot and the clutch pedal with the left foot. In the left-hand drive vehicle, the operation relationship between each pedal and each foot of the driver is the same, so the description thereof will be omitted, but the present invention is naturally applied. Also,
The explanation of the manual operation is also omitted, and only the right-hand drive vehicle will be described below.

Conventionally, in the case of an automobile with a clutch, even if the brake pedal and the clutch pedal are mistakenly stepped on, the clutch pedal can be instantly stepped on with the left foot to turn off the power, which can be prevented. However, a simple driving called an automatic vehicle was developed, and the number of vehicles having only an accelerator pedal and a brake pedal increased, and there was also a runaway accident that was supposed to be a mistake in the depression of the brake pedal and the accelerator pedal in an emergency. These are somewhat different depending on the type of vehicle, but as shown in the side view of FIG.
Is generally not horizontal, so a point P that is closest to the floor 1A of the operator's cab from a point Q at the center of the practical area of the accelerator pedal 2 (area where force is applied by stepping on the pedal) is a horizontal line including the point P. Then, a line R perpendicular to the straight traveling direction of the automobile is used as a reference line. The model is shown in the front view of FIG. 1B, and the same handling will be described below. Although not shown, it is natural that the automobile is placed almost horizontally. Therefore, the step change operation is at a position higher than the accelerator pedal 2 (about 2 to 5 cm).
Since there is a brake pedal 4 on the vehicle, it has to be moved up (arrow A) and then leftward (arrow B), which causes two movements and delays in time, so the car may be delayed, especially for people with small legs. There is a risk of stepping off. This seems to be a remnant of an underdeveloped period of a booster that requires a large amount of brake pedal step.

In addition, when the engine is idling (run-in rotation), the automobile is moved before the high speed rotation (about 1500 to 2000 rpm) to the stable low speed (500 to 1000 rpm),
In the summer, when the room cooler is operated, it will rotate at high speed, and in winter, the engine will cool down even if the vehicle is stopped for a short time, and it will rotate at high speed when idling. At this time, it is necessary to pay particular attention to the brake operation during the initial movement. Also, even in a white moving vehicle with an automatic constant-speed traveling device, when this device is in operation, the foot is far from the accelerator pedal, so the same applies when the brake pedal must be pressed quickly and reliably in an emergency. . At this time, it is sufficient to put the tip of the left foot on the brake pedal, but it is necessary to keep lifting the tip of the foot so that the pedal does not move due to the weight of the foot and the brake is not activated, so it is quite painful. Accompany. Also, braking the left foot (operation to stop the car) when entering the garage,
It's safe to teach at a driving school, but I'm not teaching.

[0005]

DISCLOSURE OF THE INVENTION Regardless of the size of the foot of a person who drives a car (driver, the same applies hereinafter), the brake pedal is quickly and reliably applied to the foot (including shoes). If you accidentally misstep the brake pedal and the accelerator pedal, you should keep your safety.

[0006]

[Means for Solving the Problems] It is easy for a driver to step on a brake pedal with a left foot.

[0007]

[Operation] Since the driver steps on the brake pedal with his left foot, he never steps on the accelerator pedal, and even if he accidentally accidentally presses the accelerator pedal with his right foot, he strongly presses the brake, so the car does not move and is safe. is there.

FIG. 2 shows an embodiment of the present invention. (A) is a plan view of each pedal, (B) is a cross-sectional view seen from the front, and is supported from a floor 1A of the operator's cab to a support rod (not shown, which is connected to a gasoline supply device) 3. An accelerator pedal 2 having a height H1 and a brake having a height H2 (the shortest line between the line R and the point S) which is also supported by a support rod (not shown, which is connected to a brake device for stopping the vehicle) 5. There is the pedal 4, and the distances L1 and L2 are close to the surface of each pedal practical area where the pedal can be applied and an operable force can be applied. In this state, the vehicle is not operated. The points Q, S, and T are located at the center of the practical range of each pedal.

Next, at a position separated from the brake pedal 4 by a distance L2 shorter than the distance L1, the height H1 is higher than the height H1.
There is a foot rest device 6 which is a vehicle safety device including a foot rest plate 60 having a support rod 61 which is extendable and contractible at a height H3 (the shortest line of the line R and the point T). The foot rest plate 60 may be provided with a stopper 60A to prevent the foot from moving more than necessary.
The support rod 61 has a pipe member 62 fixed to the floor 1A of the operator's cab, and the support rod 61 can be freely moved inside the support rod 61. A female screw 62A is made at an arbitrary position of the pipe member 62, and a knob 63A is provided. A male screw 63 having a is fitted to fix the support rod 61 at a proper position. Then, as the constituent material, metal, rubber, or plastic is appropriately selected and used.

In the above structure, the driver simply puts his left toe (including the toe with his shoes on, the same below) on the foot rest plate, and the driver instantly uses the brake pedal when necessary. You can put your foot on the brakes and stop the car safely. In this state, the operation of releasing the accelerator pedal and the operation of stepping on the brake pedal are very natural movements of a person, and there is no difference from normal walking, so that the user can use it with peace of mind. It should be noted that it is conceivable to hook the foot under the foot rest plate 60 when depressing the brake pedal and returning it, but moving the foot while stepping on is extremely small, so there is no problem. These materials are preferably covered with metal and covered with a soft material such as rubber, and a cushioning material is attached around the foot rest plate 60. For example, a soft material such as rubber or plastic is used. Good.

FIG. 3 shows another embodiment. This is based on the horizontal plane 1B including the line R, and the tilted foot rest plate 70 is supported by the support rod 71 fixed to an arbitrary portion of the vehicle body so that the driver's foot 100 can be sufficiently hooked and not shown. But,
The support rod 71 may be made extendable. And height H4
2 may be arbitrary compared to the height H1 (not shown) of the accelerator petal, but the height H5 is preferably higher than the height H1 (not shown).

4 (A) and 4 (B) show how to shift the foot and depress the brake pedal cheaply.
6A, B, C are provided to facilitate the movement of the foot. Then, as shown in FIG. 4C, the shaft 67 and the rollers 66A,
It is more convenient to use a one-way rotary bearing 68 between each of B and C. In other words, it is possible to prevent the risk that the foot, which should have been displaced due to vibration or the like during traveling, returns due to the free rotation of the roller. The rotation direction is naturally the direction of the brake petal, and the stopper 60A for preventing the foot from slipping and moving in the opposite direction is effective. Moreover, although not shown, as shown in FIG. 3, the extension may be inclined toward the heel of the foot on the floor along the longitudinal direction of each roller. The distance L2 between the pedals in this case is shown in FIG.
Is the apex of a circle, and in (B), the foot rest plate 60 is tilted as shown by the dotted line instead of being parallel to the pedal 4, as illustrated.

FIG. 5 shows an area with a large amount of traffic such as an urban area.
The brake pedal 4 is attached to the support rod 5 connected to a hydraulic device (not shown) for applying a brake so that the brake can be applied at any time without causing tiredness of the foot, and the recess 5A is also located at an arbitrary position. A roller 51 having a shaft 52 is made to bite into the recess 5A from the temporary stopper device 50, and a push plate 53A is provided on a rod 53 for supporting them, and one of them is pushed by a spring 55 fixed thereto, and the support rod is supported by the weight of the toes. Make sure that 5 is lowered and the brake is not applied. The rod 53 is supported at any place of the vehicle body, for example, through a bearing 54A of a plate 54 fixed to the floor 1A of the cab, and similarly,
The female screw 57A of the fixed plate 57 is attached to the female screw 57A having the knob 56B and the pushing plate 56A, so that the spring 5 having an arbitrary strength can be obtained.
The knob 56B is rotated by 5 to adjust the biting pressure of the roller 51. Further, instead of the spring 55, a piston method (not shown) using hydraulic pressure can be used.

The pressure applied to the brake pedal varies from 100 grams to 5000 grams depending on the weight of the foot and shoes, but in order to reduce the pressure as much as possible, for example, 2500 grams (300 grams to 20 grams for women).
Do not apply the brake up to about 00 grams,
Stick 53 to inform the driver when more
A concave portion 53B is formed at an arbitrary position, and the tip of an arm 91 of a micro switch 90 fixed at an arbitrary position is aligned with the concave portion 53B. When the rod 53 moves, the arm 91 is lifted up, and a switch 91A interlocked therewith is inserted. Electricity from the power source 94 allows the driver to use the lamp 92 and the buzzer 93 to prevent an excessive force from being applied.

[0015]

As described above, the present invention utilizes the basic movement of the human being to alternately move the left foot and the right foot. In a right-hand drive vehicle, the left foot always enters the vehicle. Therefore, the brake pedal is depressed by the left foot. Because the engine is started, you will never run out of control, you can brake quickly and reliably, you can use soft brakes (apply gradually) even in slippery places, and you can use moderate brakes and accelerators at the same time, which is a high-class technique, If you accidentally make a mistake in pressing the accelerator pedal and the brake pedal, you can avoid an accident, and you will not get tired even if you drive for a long time.
