Abstract

PURPOSE:To enable the quick start of braking operation by providing a wire for opening and closing a carbureter via a hooking piece and a cam, and connecting detachably the hooking piece and the cam to each other via the motion of an arm with the braking operation. CONSTITUTION:When acceleration function is desired, a pedal 1 is moved right and left. Then, a roller 3 as a hooking piece oscillates a cam 4 and pulls a wire 4, thereby effectuating the acceleration function. Furthermore, for sudden braking without the restoration of the pedal 1 to a predetermined position, it will do if the pedal 1 is pushed under a moving condition. In this case, the roller 3 is released from the cam 4 and this cam 4 returns to an original position due to a spring 15. According to the aforesaid constitution, braking operation can be done more quickly without any change of footing from an accelerator pedal to a brake pedal.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Yf) Main text 15J relates to a brake device for an automobile, that is, a brake device having an accelerator function.

(Prior Art) Automobiles, excluding automatic cars, are equipped with three types of pedals: accelerator, brake, and clutch pedals, and each pedal has its own function.

Each of the pedals mentioned above is operated with the foot, the accelerator and brake are depressed with the right foot, and the clutch is depressed with the left foot, but since the right foot is in contact with the accelerator and brake, it is difficult to apply a sudden brake. In other words, while driving, the right foot is always pressing down on the accelerator pedal, and from the time the danger is discovered until the brake is activated, there is a delay between (a) discovery of the danger - (b) foot from the accelerator pedal. Remove the right foot → (c) move your foot to the brake pedal (d) press the brake pedal → (e) start braking. In short, there are many situations in which a delay of 0.2 to 0.3 seconds can lead to a major accident.Also, when you are in a hurry, you may not be able to change your foot, or you may press the accelerator pedal incorrectly. There may be cases where you step in. Furthermore, there is a high risk of slipping when changing your foot to the brake pedal with rain-soaked or muddy shoes.

(Objective of the present invention) As described above, the brake pedal and accelerator pedal of a car are installed independently, so when applying the brake, it is necessary to shift the foot from the accelerator pedal. This invention is aimed at solving this problem, and eliminates the need to switch the foot from the accelerator pedal to the brake pedal, thereby making it faster and more accurate. A brake device capable of performing a brake operation is provided.

(Structure of the present invention) The present invention provides both accelerator and brake functions with one pedal, and is structured with the following features.

(1) The pedal is given a degree of freedom for movement in the left-right direction and in the front-rear direction, and has an accelerator function for the left-right movement and a brake function for the front-rear movement.

(2) By moving the pedal in the left-right direction (generally rightward), the locking piece extending from the pedal is engaged with the cam. The cam is connected to a wire leading from the opening/closing control valve of the carburetor, and by moving the locking piece, the cam follows and pulls the wire.

(3) Pushing the pedal forward moves the piston rod, transmitting pressure to the wheel attachment part via the hydraulic oil in the cylinder and applying the brakes, but in this case,
When the pedal is pressed, the locking piece that functions as an accelerator is released from the cam, and the cam is returned to its original position by a spring.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a brake device having an accelerator function according to the present invention will be described in detail based on the drawings.

(Example) Figures 1 and 2 show one form of a brake device having an accelerator function according to the present invention, in which 1 represents a pedal, 2 an arm, 3 a roller, and 4 a cam. The pedal l is swingable at a certain angle about the shaft 5 and is attached to the arm 2.
It is pivoted at the bottom end. Further, the arm 2 is attached to an upper mounting plate 7 via a shaft 6, and is pivotally supported so as to be swingable in a direction perpendicular to the swinging direction of the pedal 1. 8 is fixed, and an arm 9 is pivotally supported at the lower end of the fastener 8 via a shaft lO. A wave-shaped cam 4 is formed at the lower end of the arm 9. A roller 3 as a locking piece is engaged with the cam 4, and the cam 4 is rotated by the roller 3 as the pedal 1 moves. move it. The roller 3 is pivotally supported at the tip of the upper part of the pedal 1 via a sliding shaft 11, and the roller 3 is engaged with the plate-shaped cam 4 in a pressed state by a spring 12. Therefore, due to the movement of the roller 3, the plate cam 4 and the arm 9 are moved to the shaft 1.
A wire 14 is connected to the tip of the arm 13 protruding from the side of the arm 9 so that the arm 9 can swing around 0 and exhibit an accelerator function by the movement of the arm 9. It is led to the carburetor on-off valve. Also, the arm 9 swings counterclockwise, but the second
A stopper (not shown) is provided to prevent it from swinging clockwise from the fixed position shown in the figure.

A spring 15 is interposed between the arm 13 and the arm 13 so as to always return to the normal position. On the other hand, a piston rod 17 is connected to the back surface 16 of the arm 2 with a pin 18, and a piston 19 provided at the other end of the piston rod 17 connects the wheel mounting portion through hydraulic oil 21 in the cylinder 20. It transmits pressure to the brake equipment.

By the way, to explain the action of this brake device having an accelerator function, when the accelerator is applied as shown in FIG. 3, the medall is moved to the right. Of course, the pedal
is not a parallel movement but a oscillation around axis 5,
Edge 22 formed from the upper end to the right end of the pedal l
can be moved using the foot as a stopper. In this case, when the pedal l is moved, the roller 3 attached to the upper part of the pedal also follows, and the roller 3 is connected and fixed to the arm 13 by swinging the cam 4 around the shaft 10. Pull the wire 14 and apply the accelerator. When the user wants to release the accelerator, he or she can take his or her foot off the pedal 1 in that state, and the spring 15 acts to return the cam 4 to its original position, and the pedal 1 is also returned by the spring 24. However, when it is desired to apply the brakes, it is of course possible to apply the brakes with the pedal 1 returned to its normal position, but there are many cases where sudden braking is required. In this state, the pedal 1 can be pushed in. In this case, roller 3
is detached from the cam 4 as shown in FIG. 4, and the cam 4 is returned to its original position by the spring 15. When the accelerator is released at the same time, when the foot is released from the pedal 1, the spring 23 causes the arm 2 to be released. The pedal 1 is returned to its normal position, and the pedal 1, which has moved a certain amount, is also moved by the spring 2 attached to the side surface of the pedal 1.
4, the one-slip roller 3 engages with the cam 4.

By the way, when the brakes are applied suddenly, the pedal l is in an unstable state where it can move left and right around the axis 5.
In order to eliminate this instability, the following improvements have been made to the fitting portion between the pedal 1 and the arm 2 around the shaft 5. That is, as shown in FIG. 5, when the pedal 1 is depressed, a clockwise moment M is generated on the shaft 5. Therefore, the hole into which the shaft 5 of the arm 2 is inserted is made into a long hole, and the shaft 5 is inserted into a long hole.
A leaf spring 26 is interposed in the gap 25 between
The gap is designed to be reduced by the action of M (moment 2). Furthermore, the arm 2 and the pedal l attachment part 31
A slight gap 28 is also formed between the arm 2 and the fitting piece 27, and uneven surfaces 29 and 30 are formed on the opposing surfaces of the arm 2 and the fitting piece 27, respectively (see Fig. 6a). , the above-mentioned moment) If the gap 28 is reduced by the action of M, the double uneven surface 29.
30 fit into each other, and the pedal 1 is stabilized.

As described above, the brake device according to the present invention is also equipped with an accelerator function, and by moving the pedal 1 in the left and right direction, the cam 4 follows the movement of the pedal 1, and the cam performs the accelerator function. On the other hand, by giving the pedal 1 a movement in the longitudinal direction, a braking function is provided by a movement independent of the movement of the cam 4, and the above embodiment is a part of the constituent elements of the present invention, Although not limited to this example, the following effects can be obtained.

(Effects) (1) Since the brake device according to the present invention has an accelerator function with one pedal, there is no need to switch your foot when sudden braking is required, and you can switch your foot from the accelerator pedal to the brake pedal. Ij only for the time required for transfer
