The conventional brake pedal mechanism described above is provided on the opposite side of the accelerator pedal or on the upper and lower sides of one side, and is configured to facilitate the operability of the driver. However, there is a problem that the accelerator pedal side is erroneously operated instead of the brake pedal during braking of the kite.

It is said that such misoperations are common among people who are immature in driving skills or elderly people. In other words, there is a problem that the accelerator pedal is depressed because the braking operation at the time of braking is excessive.

In order to solve the problem that the conventional axel pedal and brake pedal are depressed by mistake, the present invention provides a recoil operation in which the brake pedal is pushed backward with a shoe shoe of a driver. The purpose is to realize a reaction type brake pedal device corresponding to the above.

In order to achieve the above-mentioned object, in a brake pedal device for an automobile corresponding to the type of repetitive driving of a driver by separating a brake pedal and an accelerator pedal in a vertical direction,
The brake drum (1) is formed in a lever shape, and the fulcrum (2) is pivotally provided by a support bolt (3) to the vehicle body inner side (i) on the accelerator pedal (a) side, and the support The bolt (3) is configured so that the lower part of the brake drum (1) can be operated rearward from the floor (f) side via a recovery spring (s) for pushing down, and the brake Connected to the braking booster (v) via a lot (r) having an adjustable part (c) at the load point (4) on the drum (1), and the brake key (1) Horizontal slide base (6) on the inner side of the lower power point (5)
The pedal shaft (7) is attached to the slide base (6) so that it can be adjusted in the front-rear direction, and the locking rings (9, 9 ') are rotatable at both ends of the pedal shaft (7). Provided, the retaining ring (9, 9
') A hard rubber roller in which the bottom is locked to the floor (f) side of the cab and a cross-shaped non-slip (p) is projected between the locking wheels (9, 9'). (8) is attached rotatably, and the braking force is controlled on the front side of the roller (8) instead of the brake pedal in proportion to the reverse type of the driver's collar (h). This is a reaction type brake pedal device. (First invention).

A second means for solving the problem is that the front side of the roller (8) between the locking rings (9, 9 ') at both ends of the pedal shaft (7) is placed on the accelerator pedal (a ) To the appropriate position on the floor surface (f) side below the rear surface of the roller (8), the front side of the roller (8) to correspond to the reverse type of the driver's shoe heel (h) It is the reaction type brake pedal apparatus comprised. (Second invention).

When the accelerator pedal (a) corresponding to the front side of the roller (8) under the brake drum (1) is an organ pedal-like hinge type, the driver's shoes (H) is set to an optimum position depending on the adjustment of the pedal shaft (7) in the slide base (6).
Further, even in a general arm type accelerator pedal (a) having a large stepping-down allowance, it can be adjusted to an appropriate position on the floor surface (f) side that does not hinder the operation of the accelerator pedal (a).

The operation of the first problem solving means is as follows. That is, the rotatable roller (8) under the lever-type brake drum (1) corresponds to the reverse of the shoe shoe (h) corresponding to the shoe shoe (h) of the driver. A braking force proportional to can be obtained.

The operation of the second problem solving means is as follows. That is, because the accelerator pedal (a) operated forward, the roller (8) of the brake pedal is inevitably acquired from the psychological aspect of operating backward. Since the acceleration / deceleration operation that depresses forward is completely different from the damping force that operates backward, an operation error can be prevented in advance.

As described above, the reaction type brake device according to the present invention includes the accelerator pedal a device operated forward and the roller 8 instead of the brake pedal b corresponding to the type of shoe heel h retracted backward. Since the switch can be operated with agility, not only can the operation be prevented during braking, but also the driver can concentrate on the other side's foot to improve the operation. There is an epoch-making effect that the kind of inevitably switching between different modes of the deceleration operation and the braking operation inevitably matches the type and psychological state.

In addition, the reaction type brake pedal (roller) device can take a rational operation posture from the floor side behind the accelerator pedal, so that one of the general drivers, of course, It also has the effect of contributing to the realization of convenient and safe driving for people with disabilities and elderly people with disabilities.

The perspective view which shows the structure form of this invention The perspective view which shows the operation form at the time of operation The constituent materials in the reaction brake pedal device are arranged in a permutation.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.

In the figure, 1 is a lever-type brake beam, 2 is a fulcrum part, 3 is a support bolt that attaches the fulcrum part 2 to the inner part i of the vehicle body in a downward-lowering manner, and s is the inside of the vehicle body Supporting point 2 from part i
A recovery spring 4 that pushes down the upper side of the brake beam 1 below the fulcrum 2 through the portion 4 is a load point provided on the upper end side of the insulator type brake beam 1. It is connected to the braking booster v through a lot r having an adjustable screw type adjusting mechanism c, and 5 is a power point under the lever type brake mechanism 1, Orthogonal slide base 6

Locking rings 9, 9 'are rotatably provided at both ends of the pedal shaft 7, A hard comb roller 8 is attached in a freely rotatable manner in place of the brake pedal b having a cross-shaped non-slip p projecting between 9 and 9 '.

The diameter of the roller 8 below the lever-type brake drum 1 is about 30 mm, and the center line l of the roller 8 is not only ordinary shoes but also various shoes. Setting the height not to exceed approximately 30 mm from the floor surface f side through the rotatable locking wheels 9 and 9 ′ so as to correspond to the portion h can improve the operability. Further, it is desirable that the width of the roller 8 instead of the pedal is formed so as to have a margin of at least about 100 mm.

And, the fulcrum 2 of the insulator type brake key 1 having the roller 8 serving as the brake pedal b.
The lower part is configured so as to be quickly lowered to the floor surface f side by a synergistic action with the pushing-down force of the recovery spring s provided at the fulcrum 2 part in combination with the own weight w of the operation mechanism.

Then, the tightening state of the pedal shaft 7 in the slide base 6 under the brake drum 1 is adjusted up and down so that the front side of the roller 8 is positioned at an appropriate position below the rear side of the accelerator pedal a. Thus, the front side of the roller 8 in place of the brake pedal b can be adjusted so as to occupy a suitable distance corresponding to the reverse type of the driver's shoe heel h. It is.

The roller 8 serving as the brake pedal can be operated by pushing it up with the driver's shoe heel in response to the inevitable reverse movement of the foot movement. In addition, it is a reaction type brake pedal device that embodies an ideal mechanism that can obtain accurate braking.
