Description

  The present invention relates to a stepping error prevention device for the purpose of preventing an accident caused by a mistake in stepping on an accelerator and a brake when driving an automobile.

  In recent years, accidents caused by misstepping of the accelerator and brake while driving a car have increased, which has become a major social problem. One of the causes of the mistake of stepping on the accelerator and brake is that the two opposite operations, “accelerate the car” and “stop the car”, are performed in the same operation, “stepping with the right foot”. It is presumed to be in the vehicle operating mechanism. For this reason, proposals have been made to improve the operation pedal of an automobile as a technique for preventing accidental accidents in depression of the accelerator and the brake (see, for example, Patent Documents 1 and 2).

  On the other hand, it is not intended to prevent accidents in the stepping on the accelerator and brake of an automatic vehicle, but it is intended to allow disabled persons with disabilities in the lower limbs to drive a car only by manual operation. A driving assistance device has been proposed (see, for example, Patent Documents 3 and 4).

An operation knob 42 is rotatably supported by a plurality of bearing members 43 fixed to the inner peripheral side of the engaging member 41.

  Here, the usage of the stepping error prevention device will be described with reference to FIGS. As shown in FIG. 1, in the accelerator operation assisting tool 20 attached to the instrument panel 13 of the automobile 10, when the driver sitting on the driver's seat 14 pushes down the operating portion 28a of the eaves member 28 with the right hand, the pressing force Is transmitted from the contact portion 28b to the pressing portion 23, and the rod 22 (the upper rod 22a and the lower rod 22b) descends along the axial direction of the cylindrical body 21. With this downward movement, the convex curved surface portion 25a of the operating portion 24 of the lower rod 22b comes into contact with the concave curved surface portion 25b of the pressure receiving portion 25a of the passive member 25 and pushes down the passive member 25, so that the accelerator pedal 11 is pushed down. .

  On the other hand, when the pressing force applied to the operating portion 28a of the eave member 28 is released by the driver's right hand, the rod 22 is raised toward the original position by the restoring force of the spring 27, and the pressing force applied to the passive member 25 is lowered. Since the force is released, the accelerator pedal 25 returns to the original state (idling state) by the restoring mechanism. Therefore, the same operation as the operation of the accelerator pedal 11 by the right foot in the existing automobile 10 can be performed by increasing or decreasing the pressing force applied to the operation portion 28a of the eaves member 28 with the right hand.

  Further, when the driver is operating the operating portion 28a of the eaves member 28 with the right hand, the handle 15 must be operated only with the left hand. However, as shown in FIG. If the operation knob 42 of the tool 40 is grasped with the left hand, the rotation operation of the handle 15 can be easily executed with only the left hand, so that the driving operation is not hindered.

  Accordingly, when a driving situation (for example, entering a garage or changing direction) is likely to cause the pedal to be depressed, the driver keeps the right foot on the brake pedal 12 and keeps the saddle member 28 with the right hand. If the accelerator pedal 11 is operated by operating the operating portion 28a and the vehicle 10 is driven, an accidental accidental depression of the pedal can be reliably prevented.

  The accelerator operation assisting tool 20 can be used simply by attaching the passive member 25 to the accelerator pedal 11 of the existing automobile 10 and attaching the tubular body 21 to the instrument panel 13 above the accelerator pedal 11 in a standing posture. Therefore, it can be mounted on the existing automobile 10 without any major remodeling. Further, as shown in FIG. 2, the accelerator operation assisting tool 20 has a simple structure and can be operated easily because a normal accelerator operation can be performed only with the driver's right hand.

  Next, as shown in FIG. 5, when the operating portion 28 a of the eaves member 28 is lifted upward, the eaves member 28 rotates and rises around the support shaft 32, and the stopper 34 is attracted to the magnet 33. The eaves member 28 is held in an upright state substantially parallel to the cylindrical body 21. Therefore, when the auxiliary device 20 is not used, or when the eaves member 28 protruding in the direction of the seat 14 (see FIG. 1) gets in the way, the eaves member 28 is erected as shown in FIG. be able to. In addition, if the force of the lying down direction exceeding the adsorption | suction force of the magnet 33 is applied with respect to the standing collar member 28, the stopper 34 will separate from the magnet 33 and the collar member 28 will return to the original state.

  When the eaves member 28 is in the upright state as shown in FIG. 5, the upper rod 22a is separated from the lower rod 22b and can be attached to and detached from the cylindrical body 21 as shown in FIG. When not using 20, the upper rod 22a can be detached from the cylindrical body 21. Further, if the upper rod 22a is separated from the cylindrical body 21, as shown in FIG. 7, the operation of the accelerator pedal 11 by the manual operation of the hook member 28 can be performed even if the hook member 28 is laid down to the use position. This makes it impossible to prevent erroneous operation of the accelerator operation assisting tool 20 itself or erroneous operation of the accelerator due to mischief.

  Further, the handle operation assisting tool 40 shown in FIG. 3 can be used immediately if an arcuate engagement member 41 having elasticity and flexibility is mounted along the inner periphery of the handle 15, and a plurality of operation knobs 42. If one of the above is gripped with the left hand, the handle 15 can be rotated slightly or greatly (when necessary, it can be rotated 360 degrees or more), and the handle operability is also good. Further, if the engaging member 41 is detached from the inner periphery of the handle 15, the handle operation assisting device 40 can be easily removed.

  The stepping error prevention device shown in FIG. 1 is attached to an automatic vehicle 10, but is not limited to this, and can be used by being attached to a manual transmission vehicle. An effect can be obtained. Further, when the stepping error prevention device of this embodiment is attached to a manually operated vehicle, the driver holds the operation knob 42 of the handle operation assisting tool 40 with the left hand while the right foot is placed on the brake pedal, It is possible to operate the clutch pedal with the left foot while operating the operation portion 28a of the eaves member 28 with the right hand, and thus excellent operability even under conditions that require delicate clutch meet operations such as starting on a steep slope. , Demonstrate safety.

  Moreover, the step error prevention device constituted by the accelerator operation auxiliary tool 20 and the handle operation auxiliary tool 40 described based on FIGS. 1 to 7 shows an example of the step error prevention device of the present invention. The stepping error prevention device of the invention is not limited to the stepping error prevention device shown in FIG.

  The stepping error prevention device of the present invention can be widely used in the field of the automobile industry as a device for preventing an accidental stepping of a pedal during driving of a vehicle.
