  By the way, the vehicular control device in the known technique of Patent Document 1 sends the supply amount of the pressure medium from the hydraulic pump to the hydraulic motor that directly drives the wheels according to the position of the control lever. The vehicle is driven forward or rearward, and the vehicle wheel is only decelerated or stopped by a hydraulic motor, and has no accelerator pad or brake pad. The vehicle equipped with can not be modified for disabled people and is manufactured as a custom-made vehicle for disabled people, so it is expensive, and by using a hydraulic motor, delicate speed adjustment and sudden braking during driving However, it is substantially difficult to prevent accidents.

  Further, the manual accelerator and brake operation lever in the known technique of Patent Document 2 is such that when the T-shaped lever is pushed forward, the brake is actuated by pulling it forward with the accelerator. Although the position of the lever can be adjusted according to the physique and degree of disability of the disabled person, the boundary position between the accelerator operation and the brake operation is clearly demarcated, and it is recognized that the position is neutral For this reason, since the accelerator and brake cannot be applied simultaneously, for example, when the vehicle stops and re-starts while climbing on a slope, the brake is released if the accelerator is operated from the brake operation. When it hits, it will come back back temporarily, and may contact the following car. Generally, a series of operations from releasing the brake to accelerating is performed, but before releasing the brake, operate the accelerator and release the brake in a state where you can start slowly, and do not perform an operation that makes a sudden start. In addition, since it is a handicapped person, there is a problem that it is inevitable that a back-up state occurs temporarily if it is necessary to start slowly by operating.

  Furthermore, the automobile driving apparatus for the physically handicapped person in the known technology of Patent Document 3 is an automatic automobile driving apparatus using an electric circuit, and a car equipped with a commercially available general engine can be modified for the disabled person. Because it is not possible and is manufactured as a custom-made vehicle for the disabled, it is expensive, and in particular, it can be switched between the accelerator lock mechanism and the brake lock mechanism according to the driving situation by operating a single lock switch However, the accelerator operation and the brake operation are not manually performed. Since the electric circuit sometimes malfunctions, the locking mechanism can only be switched, and the safety of operation cannot be ensured compared to the safety by manual operation.

  By the way, in a home with a handicapped person, an ordinary passenger car and a car for a handicapped person are prepared so that the handicapped person can also go out independently. However, due to various circumstances, for example, when a healthy person sends a disabled person to a hospital or the like, and when the disabled person wants to go home alone, the healthy person drives a car for the disabled person. The handicapped person is delivered to the hospital, and the healthy person, for example, gets on a bus and goes to the workplace as it is. At this time, the normal person usually operates the accelerator pedal and the brake pedal with his / her feet and holds the handle with his / her hand to perform the driving operation. However, in order to operate with only hands without using feet, it is necessary to have some training and to operate with awareness of differences in operation and recognition in the device. This can lead to a serious accident.

  Therefore, the present invention makes it possible to provide a low-cost vehicle that can be used by a disabled person and a disabled person so that the disabled person can operate an automobile for a disabled person in a normal state. An object of the present invention is to provide a secured vehicle operating device.

  As a specific means for solving the problems of the conventional example described above, an operating device for a disabled person and a healthy person according to the present invention has a brake pedal on the front end side and is rotatably mounted on one end side on the right side. Operating device comprising a sub-pedal plate having an accelerator pad, at least an operating lever, an accelerator lever connecting body attached to the operating lever, an accelerator lever for operating the accelerator, an accelerator differential roller, and a control member And, on the top surface of the tip side of the sub pedal plate, a bridge-like or arch-like plate having a window hole in which the tip portion of the accelerator pad is located inside and the tip portion of the accelerator lever coupling body faces is attached, The operation lever is erected on the plate so as to be able to swing, and the accelerator lever link is mounted. The front end portion of the body abuts against the front end portion side of the accelerator pad through the window hole and is set in a state where rotation is imparted, and the accelerator lever acts by the rotation of the accelerator pad, and the accelerator differential roller And a control member to drive the accelerator mechanism so that a disabled person can perform an accelerator operation and a brake operation by the operation lever, and a healthy person can use a shoe (foot) placed on the sub-pedal plate. The most important feature is that the accelerator operation and the brake operation can be performed by rotating and stepping on the accelerator pad.

  In the present invention, the operating lever is provided with a leg portion for transmitting a braking action; and the sub pedal and the brake pedal are connected by a shaft, and the brake pedal is always returned to its original position by a coil spring. As an additional requirement.

The operation device for a vehicle for both disabled and healthy persons according to the present invention is

First, the operation device for the disabled vehicle was filed as an application number 2013-115715 on May 31, 2013 by the same applicant. Basically, the operating device for the vehicle for the physically handicapped is improved so that a normal person can perform a normal driving operation.

  The operation device 1 includes a brake pedal 2 that is depressed to perform a brake operation, and an accelerator pad 3 that is rotated in a required angle range in a lateral direction to perform an accelerator operation, like a general automobile brake pedal device. The brake pedal 2 is disposed on the front side of the sub pedal plate 4 and the accelerator pad 3 is preferably disposed on the right side surface of the sub pedal plate 4. It is arranged to be able to rotate through.

  A brake arm 6 is connected to the tip end side (toe side) of the brake pedal 2, and the brake arm 6 includes a required brake mechanism including, for example, a general automobile hydraulic device, which is not shown. Are connected to each other, and the brake mechanism can be operated via the brake arm 6 by depressing the brake pedal 2 (same as the stepping-in operation). Further, the rear end portion of the brake pedal 2 is connected to the back surface of the sub pedal plate 4 on the front end portion side so as to be able to rotate via the shaft portion 7, and the coil spring 8 so that the relationship with the sub pedal plate 4 always returns to the normal position. It is energized by.

  The accelerator pad 3 is formed of a plate-like, relatively long rectangular metal plate, and its middle part is inflated outward to form a curved chevron-shaped projecting portion 3a, which is free from the end portion 3b on the shaft portion 5 side. The end 3c on the end side is left in a substantially flat plate shape, and is always biased in a closing direction by a coil spring 9 provided on the shaft 5. The accelerator pad 3 may be formed of colored reinforced plastic for the purpose of light weight.

  The sub-pedal plate 4 is configured such that a healthy person can operate the accelerator and the brake by placing his / her foot on the upper surface of the front side of the sub-pedal plate 4 by bending a substantially rectangular steel plate. An arch-shaped plate 10 is integrally provided, the end 3c of the accelerator pad 3 is located inside the right side of the plate 10, and an operation lever 11 for the disabled is provided on the upper surface of the plate 10, The operation lever 11 is configured so that the accelerator and the brake can be operated. Note that the end 3c of the accelerator pad 3 corresponds to the height of the plate 10 and is formed wide enough not to rub.

  The operating lever 11 has a spherical body 12 formed at the lower end, and the spherical body 12 is installed (accommodated) on the cylindrical base member 13 in a rotatable and non-detachable manner, and elastically formed on the upper portion of the base member 13. A cover member 14 with a gap is attached. The operation lever 11 is attached so that the upper end of the operation lever 11 is inclined at a required angle over an angle of 360 ° C. with the spherical body 12 as a base point, that is, in a swingable state.

  Further, a leg 15 for transmitting a braking action is attached near the lower end of the operation lever 11, and an auxiliary leg 15a may be attached so that the leg 15 is always located on the plate 10 side. The lever 11 is provided with a rod-like accelerator lever connecting body 16 that acts on the accelerator pad 3 at a position higher than the leg portion 15, and the distal end 17 side of the connecting body 16 is slightly bent in the horizontal direction and required. It is bent to the lower side with R. A grip portion 18 is attached to the upper end portion of the operation lever 11.

  The front end portion 17 of the accelerator lever connecting body 16 protrudes inward from a window hole 19 also serving as a guide provided in the plate 10 and is brought into contact with the end portion 3c of the accelerator pad 3, and the operation lever 11 is operated to operate the accelerator. The pad 3 is disposed so as to be pressed. Further, a fulcrum roller 21 is attached to the rear surface on the rear end side of the sub pedal 4, and the fulcrum roller 21 is placed so as to roll on a rail 23 attached to the vehicle body floor 22.

  The accelerator lever 25 is supported by a ring-shaped bearing member 27 so that one end of the accelerator lever 25 can be rotated by a shaft portion 26, and an accelerator differential roller 28 is attached to the bearing member 27. It is positioned by engaging with a trifurcated control member 30 a, 30 b, 30 c formed on the arm 29, and the accelerator arm 29 is rotatably supported by an appropriate shaft portion 32. Although not shown, the other end is connected to a general throttle mechanism (accelerator mechanism) mounted on the vehicle. A roller 31 is attached to the other end portion of the accelerator lever 25, and the roller 31 is in contact with the outer surface of the accelerator pad 3.

  The operation of the dual-use vehicle operating device for disabled persons and healthy persons of the present invention configured as described above will be described. First, the positional relationship shown in FIG. 1 is the non-operating position in the accelerator and the brake, and each mechanism such as the accelerator pad 3 including the brake pedal 2 and the accelerator lever 25 is always in an inoperative position. (For example, spring bias).

  In this state, the switch is turned on to drive the engine, and as shown in FIG. 3, for example, when a disabled person operates, the grip 18 is grasped with the right hand, and the operation lever 11 is indicated by the arrow a. Further, by moving (tilting) little by little in the right direction, the distal end portion 17 of the accelerator lever coupling body 16 pushes the end portion 3c of the accelerator pad 3 outward, whereby the angled shape of the accelerator pad 3 is increased. The protrusion 3 a pushes the roller 31 outward to rotate the accelerator lever 25, and the accelerator differential roller 28 attached to the shaft portion 26 of the accelerator lever 25 rotates counterclockwise, so that the end of the accelerator arm 29 4 acts on the control members 30a and 30b, and as shown in FIG. 4, the accelerator arm 29 is rotated (pressed down) by the shaft 32, Thus it is to operate the accelerator mechanism. In short, these operations are based on the principle of the lever and are excellent in that they can be easily operated even with a weak force.

  In this accelerator operation, the accelerator differential roller 28 rotates to contact and press either of the accelerator control members 30a and 30b, but for users who wish to make the accelerator operation faster than the standard, It can be adjusted to be accelerated by bending the front end side of the accelerator control member 30a to the left side in the drawing, that is, the accelerator differential roller 28 side. Conversely, when the accelerator operation is desired to be slower than the standard, The accelerator control member 30a can be adjusted by bending the accelerator control member 30a on the right side in the drawing, that is, in a direction away from the accelerator differential roller 28.

  In this way, in response to the driver's request, it can be accelerated or delayed in the same way as normal accelerator operation, and the operation state of the accelerator can be arbitrarily controlled to drive the driving speed of the car. It can be selected according to the person.

  During normal driving of an automobile, for example, when the brake is applied at a reduced speed by approaching an intersection, the accelerator lever 3 is gradually returned to the left and the accelerator pad 3 is returned to the original position. The roller 31 of the lever 25 returns to the skirt (valley) direction along the angled slope of the protruding portion 3a, and the accelerator lever 25 returns to the left, so that the rotation of the accelerator differential roller 28 also returns to the original position direction. As a result, the accelerator arm 29 also returns to the original position direction, so that the output of the accelerator mechanism is lowered and the traveling speed can be gradually reduced. Finally, the accelerator or the drive motor is turned off, and the operation lever 11 is moved forward. When it is pushed and tilted, the leg 15 pushes down the front side of the sub-pedal 4 and thereby the brake pedal 2 is pushed down. By operating the brake mechanism via the brake arm 6 can be stopped while adjusting the speed.

  Normally, the vehicle is operated as described above. For example, when it is necessary to apply the brake suddenly, the operation lever 11, the accelerator lever 25, etc. are returned to their original positions as shown in FIG. As shown by the arrow b, if the operation lever 11 is pushed down as it is, the brake pedal 2 is pushed forward together with the sub pedal 4, and at the same time, the tip of the accelerator lever 25, that is, the roller 31 is moved to the accelerator pad. 3 and the accelerator lever 25 is immediately returned to the original position, so that the accelerator mechanism is completely turned off, and the brake operation and the accelerator off are simultaneously performed to achieve double safety.

  In this way, when the brake is suddenly applied, the accelerator mechanism and the like are simultaneously turned off as long as the operation lever 11 is pushed forward without returning the operation lever 11, the accelerator pad 3, and the accelerator lever 25. Therefore, the brake operation is surely performed without an instant delay of switching from the accelerator to the brake. Therefore, the accelerator is turned off simultaneously with the brake operation by the push-down operation forward by the driver's operation lever 10, and safety can be ensured.

  Further, the accelerator is adjusted by adjusting the protruding length of the roller 31 of the accelerator lever 25 in the accelerator operation, and is adjusted by the control members 30a and 30b and the accelerator differential roller 28. Since the accelerator is configured to return to the fully-off state immediately, it can be easily installed if a lateral accelerator operation is adopted from the stage of designing a new vehicle or even in an electric vehicle.

  When a healthy person operates, without using the operation lever 11, as it is, for example, as shown in FIG. 1, the right foot shoe 33 is placed on the sub pedal 4 and the toe side is bridged or arched. The side of the little finger is in contact with the end 3c of the accelerator pad 3, and the accelerator pad 3 is operated by rotating the toe side to the right (clockwise) around the heel. To do.

  In this case, if the toe side is slightly lifted around the heel, the rotation operation can be easily performed in the right direction or the left direction. By this operation, the strength of the accelerator can be arbitrarily controlled. Note that the accelerator lever 25 is operated by pushing the accelerator pad 3 outward, the accelerator arm 29 is operated via the accelerator differential roller 28, and the accelerator is controlled by the operation lever 11. Since it is substantially the same as that to do, the detail is abbreviate | omitted.

  As for the brake operation, the brake pedal 2 is pushed down by the operation of depressing the sub pedal 4 with the right foot as normally performed by a healthy person. Therefore, the brake mechanism is operated via the brake arm 6 to perform the brake operation. It can be done. In this case, if you move the tip of the toe side to the left with the heel centered and step on it little by little, the accelerator operation will be released and the brake will be applied while gradually decreasing the speed. It can be stopped while adjusting.

  Furthermore, when it is necessary to apply the brake suddenly, it is possible to apply the brake suddenly by depressing the sub pedal 4 without releasing the accelerator operation. In this case, without releasing the accelerator operation by returning the toe side to the left with the heel as the center, that is, even if the accelerator is in any state (max or off), the sub-pedal 4 is even depressed. Then, as shown in FIG. 5, the roller 31 of the accelerator lever 25 is detached from the accelerator pad 3, there is no time delay for switching from the accelerator to the brake, the accelerator operation is automatically released, and only the brake operation is performed. Work. In particular, there is no possibility of accidents caused by mistakes in the conventional accelerator and brake, which is also excellent in safety.

  In the operating device for a vehicle for both disabled and healthy persons according to the present invention, a plate 10 formed in a bridge shape or an arch shape is integrally provided on a sub pedal plate 4 provided with a brake pedal 2 and an accelerator pad 3. The end 3c of the accelerator pad 3 is located inside the right side of the plate 10, an operation lever 11 for the handicapped is provided on the upper surface of the plate 10, and an accelerator lever connecting body 16 is provided on the operation lever 11. The distal end portion 17 of the coupling body 16 is disposed so as to contact the end portion 3c of the accelerator pad 3, and the accelerator pad 3 is disposed to be pushed outward by operating the operation lever 11. An accelerator lever 25 whose tip abuts against the accelerator pad 3 is provided, and control members 30 a, 3 are provided between the accelerator lever 25 and the accelerator arm 29. b and an accelerator differential roller 28. The handicapped person can operate the vehicle by manually operating the operation lever 11 left and right or back and forth. Put your right foot on the left side, move the toe side to the left and right to operate the accelerator, and depress the sub pedal 4 to operate the brakes, so you can control the car. Even if the operation device of the present invention is installed in place of the accelerator, it can be adjusted so as not to give a sense of incongruity to the disabled and healthy people according to the timing of the accelerator that each vehicle model originally has, and the driving operation. Even when the brakes are applied suddenly, it is possible to operate the brakes accurately without making a mistake between the accelerator and the brake. As the vehicle operating device for handicapped and healthy subjects combined it can be widely used in various automobiles.
