Description

[Detailed Description of the Invention] The present invention relates to a vehicle operation pedal such as a clutch pedal or a brake pedal.

2. Description of the Related Art In vehicles, it is widely practiced to adjust the seat position in the longitudinal direction of the vehicle according to the height of the driver. However, it is not possible to achieve an ideal driving posture simply by adjusting the seat position. In addition to the steering wheel, a vehicle is equipped with clutch, brake, and other pedals, so even if the seat position is optimally adjusted relative to the steering wheel, it will not be in the optimal position relative to the pedals; This is because if the position is set at the optimum position with respect to the pedals, the position relative to the steering wheel will be inappropriate. Therefore, in order to enable both tall and short people to have a truly ideal driving position, the seat position should be adjustable, and the pedal position should also be adjustable in the longitudinal direction of the vehicle. It is necessary to do so. However, since the pedal is connected to the clutch, brake, etc., it is necessary to be able to adjust the position without affecting these, and the position can be adjusted relatively easily. It must be of a type that does not easily move once the adjustment is completed and fixed. This is because it would be extremely dangerous if the pedal were to shift in the front-rear direction when the pedal is depressed.

With this background in mind, the present invention provides an adjustable pedal whose position can be easily adjusted in the longitudinal direction, and which does not easily move once the adjustment is completed and fixed. It was created with the purpose of A plurality of notches are formed in at least one side wall of the elongated hole at intervals in the longitudinal direction of the elongated hole, and two notches are formed in the upper end of the lower arm to which the pedal pad is attached at the lower end at intervals in the longitudinal direction of the vehicle. A book protrusion is provided, one of the protrusions is fitted into the elongated hole, and the other is inserted into the elongated hole or another elongated hole formed approximately parallel to the elongated hole, and the generation of the problem occurs due to the weight of the lower arm. The lower arm is stably supported by the upper arm in a state where at least one of the two protrusions is engaged with one selected from the plurality of notches due to the rotational moment. be.

In this way, the rotational moment generated in the lower arm based on the pedal force applied by the driver to the pedal pad is reduced by the engagement between the two protrusions provided on the lower arm and the elongated hole provided on the upper arm. Since the force in the longitudinal direction of the vehicle is received by the engagement between the protrusion and the notch, there is essentially no need to fix the lower arm and the upper arm using screw means or the like. Therefore, even if a screw means or the like is provided, it is sufficient that it is simple enough to prevent the protrusion from coming off the notch, and it is also possible to prevent the protrusion from coming off the notch using a spring means. becomes. As a result, the position of the pedal can be adjusted very easily, and once the adjustment is completed, there is no fear that the lower arm will shift relative to the upper arm when the pedal is depressed.

A few embodiments of the present invention will be described below in detail with reference to the drawings.

Figure 1 shows an embodiment in which the present invention is applied to a clutch pedal, where 2 is a toe board and 4 is a toe board.
is the pedal bracket fixed to it. A clutch pedal 6 is attached to the pedal bracket 4 so as to be rotatable about the horizontal line, and is configured to actuate a piston in a master cylinder 10 via a push rod 8 to generate hydraulic pressure for closing the clutch. .

The clutch pedal 6 is divided into an upper arm 12 and a lower arm 14. The upper arm 12 has an upper end attached to the pedal bracket 4 by a pivot 16, and a lower end provided with a connecting portion 18 extending in the longitudinal direction of the vehicle. As is clear from FIG. 2, the connecting portion 18 is bifurcated, and the upper end of the lower arm 14 is inserted between the connecting portions 18. A pedal pad 20 is fixed to the lower end of the lower arm 14.

As is clear from FIG. 3, the connecting portion 18 is formed with an elongated hole 22 extending in the longitudinal direction of the vehicle and another elongated hole 24 parallel to the elongated hole 22. A plurality of rectangular notches 26 are formed in the lower side wall of the elongated hole 24 at equal intervals in the longitudinal direction.

On the other hand, a pin 28 and a bolt 30 are attached to the upper end of the lower arm 14. The pin 28 is positioned forward and upward relative to the bolt 30, and as seen in FIG.
It is press-fitted so as to penetrate the upper end of the holder, and the protrusions on both sides are fitted into the elongated hole 22. On the other hand, the bolt 30 is slidably inserted into a through hole formed in the lower arm 14, and is fitted into the elongated hole 24 at the portion protruding from both sides of the lower arm 14, and protrudes from the elongated hole 24. Washers 32 are fitted to both ends, and wing nuts 34 are screwed together.
One of the two wing nuts 34 is fixed to the bolt 30 by brazing or the like.

As is clear from FIG. 1, the lower arm 14 is
Since the pedal pad 20 is bent from the front to the rear of the vehicle and the pedal pad 20 is fixed to the lower end thereof, a clockwise rotational moment is generated due to its own weight when the upper end is supported. This rotational moment therefore causes the pin 28 to be pressed against the upper side wall of the elongated hole 22 and the bolt 30 to be pressed against the lower side wall of the elongated hole 24.
However, since the notch 26 is formed in the lower side wall of the elongated hole 24 as described above, when the bolt 30 is in a position that matches this notch 26, the bolt 30 is moved by the above-mentioned rotational moment. Tsute notch 2
It will be in a state where it is strongly pressed against the bottom surface of 6. Moreover, when the driver applies pedal force to the pad 24, the rotational moment generated in the lower arm 14 is also a clockwise moment, similar to the rotational moment described above, so that when the pedal is operated, the pin 28 is inserted into the elongated hole 24. The bolt 30 is pressed against the upper side wall of the
The tendency of the bolt 30 to be pressed against the bottom surface of the notch 26 is only promoted, and no force is exerted in a direction to separate the bolt 30 from the notch 26. Therefore, bolt 3
0 is fixed to the connecting portion 18 by the wing nut 34 in order to improve safety, and the wing nut 34 may be omitted.

In the device configured as described above, when it becomes necessary to adjust the position of the pedal pad 20 back and forth, loosen the wing nut 34 and adjust the position of the lower arm 1.
4, for example, the pedal pad 20, is lifted upward against the weight of the lower arm 14, the lower arm 14 rotates about the pin 28, and the bolt 30 is removed from the notch 26. In this state, the lower arm 14 can be moved in the longitudinal direction of the vehicle, and when the bolt 30 is positioned above the desired notch 26, lifting of the pedal pad 20 is released, and the bolt 30 moves into the notch 26. engage with. Subsequently, the adjustment work is completed by tightening the wing nut 34, and this adjustment work is extremely easy.

If the position of the pedal pad 20 can be adjusted back and forth in this way, it will be possible to adjust the position of the pedal pad 20 for a tall person M as shown in Fig. 4.
In 1, by moving the seat S backward and the pedal pad 20 forward, both the distance to the steering handle H and the distance to the pedal pad 20 can be optimized, and the user can maintain an ideal posture. Conversely, a person M2 who is short, such as a woman, can drive in the same ideal posture by moving the seat S forward and the pedal pad 20 backward. It is possible.

Another embodiment of the present invention is shown in FIGS. 5 and 6. In this embodiment, the connecting portion 44 of the upper arm 42 is not bifurcated, and only one elongated hole 46 is provided. A plurality of U-shaped notches 48 are formed in the upper side wall of the elongated hole 46 at equal intervals in the longitudinal direction of the vehicle. Furthermore, two pins 52 and 54 are erected at the upper end of the lower arm 50. The pin 52 is located forward and above the pin 54, and the pins 52, 5
4 are both fitted into elongated holes 46. The pin 52 has a head 56 as shown in FIG. 6, and the head 56 and the lower arm 50 themselves sandwich the upper arm 42 from both sides, so that the lower arm 50 is oriented laterally with respect to the upper arm 42. Preventing them from moving.

On the other hand, a washer 58 and a torsion spring 60 are fitted into the pin 54, and are prevented from coming off by a head 62. A pair of arm portions of the torsion spring 60 are respectively engaged with the connecting portion 44 and the lower arm 50, and urge the lower arm 50 to rotate clockwise around the pin 54.

In this embodiment, when it is necessary to adjust the position of the pedal in the longitudinal direction, the pin 52 is rotated by rotating the lower arm 50 counterclockwise against the biasing force of the torsion spring 60. After being removed from the notch 48 and moved to a desired position, another notch 48 is removed.
This has the advantage of making the adjustment work easier.

Although the two embodiments of the present invention have been described in detail above, the present invention can be implemented with various modifications based on the knowledge of those skilled in the art, such as forming notches in the upper and lower side walls of the elongated hole. It goes without saying that the present invention can be applied not only to clutch pedals but also to brake pedals and the like.
