  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.

  Therefore, a vehicle driving or operating device for a handicapped person according to the prior art, particularly a handicapped person with a physical disability, can be operated easily and reliably, and is equipped with a commercially available general engine. It is possible to easily improve the cost and provide it at low cost, and to solve the problem of ensuring safety.

In this invention, when the operation lever is pushed down to the brake acting side (forward), the tip of the access lever is detached from the accelerator pad and the accelerator mechanism is turned off ; and the sub pedal and the brake pedal are connected by a shaft. And an additional requirement that the brake pedal be spring-biased so that it is always returned to its original position by the coil spring.

  In the operating device for a vehicle for a handicapped according to the present invention, the driver can control the traveling speed of the vehicle by operating the accelerator by pushing or returning the operating lever in the lateral direction or the front-rear direction. Even when the brake is applied suddenly, the operation lever is simply pushed forward, so that the brake can be operated quickly and accurately without the mistake of the accelerator and the brake. And has an excellent effect of high safety.

Next, the present invention will be described in detail based on preferred embodiments.
An operation device for a vehicle for a disabled person according to the present invention will be described with reference to FIGS.
First, in FIG. 1, an operating device 1 for a vehicle for a disabled person is rotated in a required angle range in a lateral direction with a brake pedal 2 that is depressed to perform a braking operation, in the same manner as a brake pedal device of a general automobile. An accelerator pad 3 for operating the accelerator is provided, and these are provided on a relatively wide sub-pedal plate 4. The brake pedal 2 is disposed on the front side of the sub-pedal plate 4, and the accelerator pad 3 is disposed on the sub-pedal plate 4. Preferably, it is rotatably arranged on the right side surface via the shaft portion 5.

  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.

An operation lever 10 is provided on the sub pedal plate 4. The operation lever 10 has a spherical body 11 formed at the lower end, and is installed (accommodated) in a state where the spherical body 11 is rotatable and does not detach from the cylindrical base member 12, and is elastically formed on the upper portion of the base member 12. A cover member 13 with a gap is attached. The operation lever 10 is attached in such a manner that the upper end can be inclined at a required angle over a 360 degree angle with the spherical body 11 as a base point, that is, can swing.

  Further, a leg 14 for transmitting a braking action is attached near the lower end of the operation lever 10, and an auxiliary leg 15 is attached, and a rod-like accelerator lever connector 16 acting on the accelerator pad 3 is provided in the vicinity thereof. It is attached via a part 17 and a grip part 18 is attached to the upper end part.

  An accelerator operating roller 20 is attached to the distal end portion of the accelerator lever connecting body 16 via a bearing portion 19, and the accelerator operating roller 20 is disposed in a state where it can be pressed against the accelerator pad 3. 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 mounted so as to roll on a rail 23 attached to the vehicle body floor 22. Note that a stopper member 24 is attached to the front right upper surface of the sub pedal 4 so that the front end 3c of the accelerator pad 3 abuts (buckles). The stopper member 24 has a function of generating a sound when the accelerator pad 3 is loose.

  One end of the accelerator lever 25 is supported by a ring-shaped bearing member 27 so that it can be rotated by a shaft portion 26. An accelerator differential roller 28 is attached to the bearing member 27, and the accelerator differential roller 28 is an accelerator. 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.

  Regarding the operation device for a vehicle for a handicapped person of the present invention configured as described above, the operation 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, the grip 18 is gripped with the right hand, and the operation lever 10 is gradually moved to the right as indicated by the arrow a. By moving (inclining), the accelerator operating roller 20 of the accelerator lever connecting body 16 pushes the accelerator pad 3 outward, whereby the angle-shaped protrusion 3a of the accelerator pad 3 pushes the roller 31 outward. The accelerator lever 25 is rotated, and the accelerator differential roller 28 attached to the shaft portion 26 of the accelerator lever 25 rotates counterclockwise, so that it acts on the control members 30a and 30b at the end of the accelerator arm 29. As shown in FIG. 4, the accelerator arm 29 is rotated (pressed down) by the shaft portion 32, whereby the accelerator mechanism is It is to work. 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 returned little by little to the left to return the accelerator pad 3 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, 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 10 is moved forward. When it is pushed and tilted, the leg portion 14 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, as shown in FIG. 5, the operation lever 10, the accelerator lever 25, etc. are returned to their original positions. As shown by the arrow b, if the operation lever 10 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.

  As described above, when the brake is suddenly applied, the accelerator mechanism and the like are simultaneously turned off as long as the operation lever 10 is pushed forward without returning the operation lever 10, 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, the control members 30a, 30b and the accelerator differential roller 28, and also in the case of a brake operation. 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.

  The vehicle operating device for a disabled person according to the present invention includes the control members 30a and 30b and the accelerator differential roller 28 between the accelerator lever 25 and the accelerator arm 29, so that the timing of accelerator start and acceleration can be controlled. Since it can be adjusted arbitrarily, even if it replaces the pedal type brakes and accelerators that are mounted on the conventional models of each manufacturer, and the sub-pedal 4 with the operation lever 10 is mounted, each model originally has it. It is possible to adjust the timing of the accelerator so as not to give the driver a sense of incongruity, and the driver operates the accelerator by pushing or returning the operating lever 10 in the lateral direction or the front-rear direction. Even if the brake is suddenly applied during the control, the operation lever 1 is controlled. Is simply pushed forward, so that the brakes can be operated quickly and accurately without any mistakes in the accelerator and brakes. It can be widely used.
