DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary brake device for a motor vehicle capable of operating a brake in a passenger seat and a brake operating mechanism constituting the device.

[0002]

2. Description of the Related Art The inventor first sets an auxiliary brake mechanism having an auxiliary brake pedal in a passenger seat, and transmits the depression operation of the auxiliary brake pedal to a brake operating mechanism provided in a driver's seat using an operation cable. Patent No. 2809 Auxiliary braking device for automobiles that uses the original brake
No. 387. Since the auxiliary brake device can be attached to and detached from any type of vehicle, it can be directly attached to a vehicle to be driven by a driver. Therefore, it is suitable for a paper driver or the like who wants to re-learn the course as well as a person who wants to learn a new driving technique.

[0003]

However, in the case of the above-mentioned patent, the mounting posture of the connecting frame connecting the auxiliary brake mechanism and the brake operating mechanism is fixed.
The connection frame had to be adapted to the type and type of automobile to which it was applied. That is, the connecting frame needs to be provided so as not to obstruct the occupant, and it is necessary to extend the connecting frame along a portion of the front instrument panel which also obstructs as little as possible.
However, since the height and distance to the instrument panel vary depending on the vehicle, it was necessary to specially manufacture a connecting frame suitable for the vehicle type.

[0004] Of course, the conventional connecting frame is also adjustable in height and in the left-right direction so that the position can be adjusted. However, since the connecting posture with the auxiliary brake mechanism is fixed, this position adjusting structure alone is sufficient. Couldn't cover it. The present invention addresses such a problem, and in short, compensates for this disadvantage by allowing the inclination angle of the connecting frame rising from the auxiliary brake mechanism to be changed. In addition, the present invention makes the brake operating mechanism that constitutes this device efficient.

[0005]

SUMMARY OF THE INVENTION In view of the above problems, the present invention transmits the operation of an auxiliary brake mechanism placed on the floor of a passenger seat to a brake operating mechanism that operates a brake pedal of a driver seat via an operation cable. An auxiliary brake device for an automobile, wherein the auxiliary brake mechanism and the brake actuating mechanism are connected by a connecting frame, and the connecting posture of the auxiliary brake mechanism and the connecting frame is bendable. It was done.

According to the present invention, the connecting posture between the auxiliary brake mechanism and the connecting frame is made bendable, so that the connecting frame is most efficiently raised from the auxiliary brake mechanism to approach the instrument panel. Can be. For this reason, the connection frame can be prevented from protruding into the space on the front side of the passenger seat as much as possible.

In addition, the connecting frame extends vertically from the auxiliary brake mechanism on the front passenger seat side so as to extend and contract along the instrument panel, and extends beyond the center console. Longitudinally along the side wall of the instrument to below the instrument panel,
Next, if it extends horizontally and then extends vertically to the front of the brake pedal, an ideal bridging mode is obtained.

Further, the present invention provides a means in which the above-mentioned auxiliary brake mechanism is fitted and fixed to one of a plurality of fitting portions provided in front and rear on a mat laid on the floor of the passenger seat. In this case, by providing a non-slip structure or the like on the back surface of the mat, the auxiliary brake mechanism does not move. In this case, since a plurality of fitting portions are provided in the front and rear, the front and rear positions can be adjusted by selecting one of them. The depth of the passenger seat floor varies depending on the size of the car, so it is designed to cope with this.

Incidentally, if the auxiliary brake mechanism is fixedly mounted on the floor using a fastener such as a screw, it is not preferable because it is a so-called remodeled vehicle. For this reason, conventionally,
The frame on which the auxiliary brake mechanism was mounted was merely placed on a mat laid on the floor. However, in this case, when the pedal was depressed, the frame would move and adversely affect the brake operating mechanism. But,
This measure has been eliminated by taking this measure.

Further, the present invention relates to an auxiliary brake device for a vehicle, which transmits an operation of an auxiliary brake mechanism placed on a floor of a passenger seat to a brake operating mechanism for operating a brake pedal provided on a driver seat via an operation cable. When the operating mechanism is attached to the arm portion of the brake pedal, a mounting plate extending toward the front side of the mounting bracket, and is pivotally attached to the mounting plate and linked to the operation cable to operate the auxiliary brake mechanism, the arm portion is actuated. To apply a brake, but when the brake pedal is depressed, a brake actuating mechanism constituting an auxiliary brake device for an automobile, characterized in that the brake actuating mechanism is constituted by a rotating plate remaining at that position.

Since the brake operating mechanism is composed of a mounting bracket, a mounting plate, and a rotating plate, these are one set, and mounting and dismounting can be performed by this set. You can save much trouble. In this case, if the front and rear positions and the left and right inclination angles of the mounting plate with respect to the mounting bracket can be adjusted, the mounting plate can be mounted on and removed from any type of vehicle.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory plan view showing an example of an auxiliary brake device for an automobile according to the present invention. This auxiliary brake device acts on an auxiliary brake mechanism 10 provided in a passenger seat and a brake pedal 12 in a driver seat. The connecting frame 16 is connected to the brake operating mechanism 14 provided.
, And the two 10 and 14 are connected by an operation cable 18.

FIG. 2 is a side view of the brake operating mechanism 14, FIG. 3 is an enlarged side view of a main part, and FIG. 4 is a sectional view taken along the line AA of FIG. A mounting bracket 20 attached to the portion 12a, and a mounting plate 2 extending from the mounting bracket 20 to the near side.
2, a rotation plate 24 rotatably mounted on the mounting plate 22, a cable holder 26 rotatably mounted on the rotation plate 24, and the like.

The mounting bracket 20 has a substantially C-shape in plan view in which a wing bolt 28 is screwed on a rear surface and a side surface. It is inserted into the arm portion 12a at a considerably higher position, and is fixed by tightening with the wing bolt 28. At this time, the push screw 27 having a sharp point is pushed into the arm portion 12a from the near side of the mounting bracket 20, thereby preventing the arm from falling. Further, a slip-off prevention body 29
Is attached, and the portion where there is no glue is set as a step so that the mounting bracket 20 is fitted to the step so as to slip off.

As described above, the thorough prevention of detachment and displacement of the mounting bracket 20 is intended to ensure safety. The reason why the mounting position of the mounting bracket 20 is set significantly above the pedal portion 12b is to prevent a foot from hitting when stepping on, and the wing bolt 28 is used because a tool or the like is not used. Yes, it does not correspond to a modified car.

The mounting plate 22 is L-shaped with a protruding piece 22a protruding leftward in a plan view, and further includes a screw rod 30 (30a is a positioning nut) on the back side from the protruding piece 22a. It is made to protrude. Then, the screw rod 30 is passed through a screw hole formed in a protruding piece 20 a protruding to the side (left side in plan view) of the mounting bracket 20 to integrate the two. Therefore, by adjusting the length of the screw rod 30, the front-rear position of the mounting plate 22 can be adjusted, and the left and right inclination angles can be adjusted.

The mounting plate 22 has a portion extending upward from the protruding piece 22a. A pin 32 is passed through the upper portion of the mounting plate 22, and the rotating plate 24 is placed around the pin 32 on the left side of the mounting plate 22 in plan view. It is rotatable and is hung. The cable holder 26 described above is rotatably mounted on the left side of the lower end of the rotating plate 24 in a plan view by a mounting shaft 34. In this case, the attachment of the cable holder 26 to the rotating plate 24 is also performed by the wing nut 34.
The tool is not used due to a or the like.

As the operation cable 18 of this embodiment, a double cable composed of an inner wire 18a and an outer cable 18b is used, and the end of the outer cable 18b is fixed to the cable holder 26. . Accordingly, when the inner cable 18a is fixed and the outer cable 18b is pushed inward, the rotating plate 24 rotates backward. At this time, the protruding piece 22a of the mounting plate 22 is pushed, and the brake pedal 12 is pushed down to release the brake. It will work. At this time, a spacer 23 or the like is inserted between the rotation plate 24 and the mounting plate 22 so that the rotation plate 24 is aligned with the screw rod 30 mounted on the mounting bracket 20, and the force is applied. I try to transmit it efficiently.

FIG. 5 is a side view of the brake operating mechanism 14 viewed from the side opposite to FIG. 3. When the brake pedal 12 is depressed, the mounting plate 22 is pulled to the rear side, while the rotating plate 24 is Stays in place. Accordingly, the outer cable 18b is also pulled slightly upward, but does not move back and forth, does not require a large force to depress the brake pedal 12, and does not differ from a normal depression feeling.

By the way, the mounting plate 22 can be adjusted in the front-rear position with respect to the mounting bracket 20 by adjusting the screw rod 30, but it has also been described that the left and right inclination angles can also be adjusted. This is because some of the arm portions 12b of the brake pedal 12 are slanted, and in such a case, the angle is adjusted so that the turning plate 24 is vertical and the turning is smooth. . In order to secure the above operation for a long time, the rotating plate 24
The projecting piece 22a of the mounting plate 22 is brought into contact with the projecting piece 22a without a gap over the entire length.

FIG. 6 is a side view of the auxiliary brake mechanism 10, and FIG. 7 is a plan view. The auxiliary brake mechanism 10 includes a frame 36, an auxiliary brake pedal 38 and a footrest 40 provided on the frame 36. The frame 36 is placed on the floor 42 of the passenger seat.

A cable holder 52 for holding the outer cable 18b is mounted on the base column 36c by a mounting shaft 52a so as to be rotatable by a bracket 50 extending from the front leg 36a. In addition, the right connecting material 36
The footrest 40 is attached to e. still,
The footrest 40 is provided to the right of the auxiliary brake pedal 38, and is mounted at a height substantially equal to that of the brake pedal 38a so as not to interfere with the depression of the brake pedal 38a.

It is also conceivable that the frame 36 is not placed directly on the floor 42 but is laid on a mat 54. At this time, if the frame 36 is fixed to the mat 54 and an appropriate non-slip structure is provided on the back surface, the frame 36, that is, the auxiliary brake mechanism 10 does not move, and the operation is stabilized. For example, mat 5
4. A fitting portion 56 to which the rear leg 36b of the frame 16 can fit.
Is provided and can be operated with one touch by fitting. If a plurality of the fitting portions 56 are provided in the front and rear, the front and rear can be adjusted without moving the position of the mat 54.

Thus, when the pedal portion 38b of the auxiliary brake pedal 38 is depressed, the arm tip portion 38c at the tip end of the arm portion 38a rotates forward, and the inner wire 18a
From the outer cable 18b. At this time, if the inner 18a of the brake operation mechanism 14 is fixed, the outer cable 18b, that is, the rotating plate 24 is pushed inward, and the brake pedal 12 is depressed to operate the brake. Become. Note that the pedal portion 38b is constantly springed upward by the spring 58, and automatically returns to its original position when the foot is released from the pedal portion 38b.

The connecting frame 16 connects the auxiliary brake mechanism 10 and the brake operating mechanism 14 described above. The connecting frame 16 of the present embodiment is formed of a pipe body, and is connected to the auxiliary brake mechanism 10 by the left connecting portion 1.
6a, a left portion 16b connected to the left connecting portion 16a and extending rightward, a right portion 16c connected to the left portion 16b and extending rightward and further extending longitudinally, Part 16c
And a right connecting portion 16d connected to the brake operating mechanism 14.

The left connecting portion 16a has one end connected to the base column 36c of the frame 36 by the connecting bolt 60, and the other end inserted and connected to the left side portion 16b so as to be able to be taken in and out. It is. Therefore, the connection angle between the left connecting portion 16a and the left side portion 16b can be freely adjusted. The left portion 16b has an elbow shape including a vertically extending portion and a horizontally extending portion, and a right portion 16c is inserted and connected to the right end so as to be able to be taken in and out.

For this purpose, tightening and loosening members 62 are provided at both ends of the left side portion 16b to adjust the amount of the left connecting portion 16a and the right side portion 16c. The operation cable 1 described above
The cable 8 is also extended between the passenger seat and the driver's seat. However, if the operation cable 18 is laid on the floor, it may hinder driving. Therefore, the operation cable 18
Is suspended from the connecting frame 16 by the suspender 19,
It passes through a high position along the connection frame 16.

The right side portion 16c has a two-stage crank shape in which a portion extending horizontally from the left side portion 16b, and a portion extending vertically, horizontally, and further vertically from the left portion 16b are successively formed. The right side portion 16c extends laterally along the front surface of the instrument panel, as described later, but extends beyond the center console, longitudinally forward along the side wall of the instrument panel, and then laterally, and further extends to the brake pedal. It extends vertically to the back of twelve.

Further, the inner wire 1 is connected to the right connecting portion 16d.
A holder fixing member 66 for fixing a wire holder 64 holding the wire 8a to be rotatable around a mounting shaft 64a is fixed by bolts 68 or the like. In this case, the inner wire 1
A screw rod 18c is provided at the end of 8a, so that it can be adjusted forward and backward with respect to the wire holder 64. Also, the right connecting portion 1 for attaching the holder fixing member 66
6d is provided with a plurality of bolt mounting holes 68a at the front and rear. By changing the position of the mounting holes 68a and passing the bolts 68, the holder fixing member 66 can also be moved back and forth. Depending on the type of vehicle, the space length below the brake pedal 12 is different, so that it is possible to cope with this.

In this case, the angle of the left connecting portion 16a is adjusted and the amount of expansion and contraction of the left portion 16b is adjusted.
6b and the right side 16c are connected to the instrument panel 70.
It is preferable to adjust the amount of expansion and contraction of the right side portion 16c so that the vertically extending portion is along the right side wall of the center console 72 without obstruction. In addition, a stay 76 having a rear end fixed to a seat mounting bolt 74 or the like can be connected to a vertically extending portion of the right side portion 16c. In this case, the stay 76 is also provided with an adjusting portion 78 having the above-described tightening and loosening tools 62 at both ends, so that the height and length thereof can be adjusted.
A mounting portion 77 having a long hole 77a is formed at a location on the right side portion 16c where the stay 76 is mounted, and the mounting position of the stay 76 can be changed using a hexagon socket head bolt 79 or the like that is firmly tightened. It is appropriate to keep it.

The method of mounting the auxiliary brake device described above will be described.
0 and the brake operating mechanism 14 are connected in advance by the connecting frame 16 (the operating cable 18 is also connected). At this time, each adjusting portion of the connection frame 16 is loosened so that adjustment can be performed. This set is brought into the vehicle, a mat 54 is laid on the passenger seat, and the rear leg 36b of the auxiliary brake mechanism 10 is pushed into the fitting portion 56 at a suitable position of the mat 54, so that the brake operating mechanism 14
The mounting bracket 20 is mounted on the brake arm 12a of the driver's seat as described above.

In this state, the angle, height and lateral length of the connecting frame 16 are adjusted so that the connecting frame 16 extends laterally along the instrument panel 70 which does not interfere with the driver or instructor. Then, if the stay 76 is adjusted and attached, the attachment is completed. In addition, the auxiliary brake mechanism 10
The brake operating mechanism 14 and the brake operating mechanism 14 may be brought into the vehicle in a separated state, and after setting each, the connecting frame 16 and the operating cable 18 may be connected while being adjusted.

Furthermore, if some kind of preparations are made for a new vehicle in consideration of this, installation labor and members can be greatly reduced. FIG. 8 is a side view showing such a case. The first is that the rear side wall of the brake pedal 12 is provided with a mounting seat 80 or the like in which a tap hole 80a for fixing the wire holder 64 is formed. (Always keep it hidden by a cover). In this case, a metal fitting 82 for rotatably holding the wire holder 64 is prepared, and the metal fitting 82 is fastened to the tap hole 80 of the mounting seat 80 by a fastening tool.
The connection frame 16 and the like are not required since it only needs to be fixed to a.

In this case, since only the operation cable 18 is passed between the passenger seat and the driver's seat, it may be passed at an appropriate height. Specifically, the flexible stand 86 fixed by the sheet mounting bolt 74 may be erected, and the operation cable 18 may be hung on the flexible stand 86 by the hanging member 19. Further, if a hole 84 is made in the arm portion 12 of the brake pedal 12 (ideally, this is formed when a new vehicle is used), the time and effort of mounting the hole 84 becomes even easier.
That is, it is only necessary to mount the mounting bracket 20 of the set of the brake operation mechanism 14 using the hole 84.

Next, a method of using the auxiliary brake device will be described. An instructor sits in a passenger seat and instructs. During the instruction, when the instructor feels danger, he steps on the auxiliary brake pedal 38b. Then, the inner wire 18a is pulled, and the outer cable 18b on the brake operation mechanism 14 side is pushed by the reaction, but at this time, the inner wire 18a is pulled.
Since a is fixed by the connecting frame 16, the rotating plate 24 to which the outer cable 18b is mounted pushes the protruding piece 22a of the mounting plate 22, and the force is transmitted to the arm 12a via the screw rod 30 and the mounting bracket 20. .
Accordingly, the brake operates in the same manner as when the arm 12a is lowered and the pedal 12b is depressed. On the other hand, when the driver steps on the pedal portion 12b, the rotating plate 24 stays in place and the mounting plate 22 simply moves, so that the movement does not become heavy or a sense of incongruity does not occur.

[0037]

As described above, according to the auxiliary brake device for a vehicle according to the present invention, since the connecting posture between the auxiliary brake mechanism and the connecting frame is made bendable, the connecting frame is moved from the auxiliary brake mechanism to the instrument panel. Can be most efficiently launched and approached. For this reason, the connection frame can be prevented from protruding into the space on the front side of both the passenger seat and the driver's seat as much as possible. Further, according to the brake operating mechanism constituting this device, these are one set, and mounting and dismounting can be performed with this set, which is simple.
