Description

  The present invention relates to an auxiliary brake device for an automobile capable of pushing a brake arm of a driver's seat and applying a brake by operating an auxiliary brake mechanism placed in a passenger seat.

  The present inventor previously installed an auxiliary brake mechanism having an auxiliary brake pedal in the passenger seat for driving skill learners and paper drivers, and operated an operation cable to depress the auxiliary brake pedal provided in the auxiliary brake mechanism. Japanese Patent Application Laid-Open Publication No. 2004-259561 proposes an auxiliary brake device for an automobile that transmits the original brake to the brake operating mechanism provided in the driver's seat using the. This auxiliary brake device can be removably attached without any special work on the vehicle body, so it can be directly attached to the vehicle where the driving skill is to be learned. Is not left.

  As an operation cable in this case, a double cable composed of an inner wire and an outer cable is efficient. When the double cable is used, the inner wire is connected to the auxiliary brake pedal and the fixed point on the back of the brake, and the outer cable is connected to the fixed point of the auxiliary brake mechanism and the brake pedal. Can be pushed in. In order to make this possible, it is necessary to hold the inner wire firmly behind the brake arm.

In this case, as can be seen in Patent Documents 2 and 3 below, if the floor or the like is crafted in some way, it can be easily fixed. However, in that case, there is a risk of illegal modification, and above all, the vehicle body is damaged. As described above, the present inventor is based on the concept of implementing this type of auxiliary brake device without modifying the vehicle body and without damaging the vehicle body, and this is very difficult to hold. In the previous proposal of the present inventor, the holding tool for holding is connected to the auxiliary brake mechanism by a connecting pipe, and the connecting pipe is fixed by a seat bolt or the like to enhance the holding. This is the goal, but I was looking for other ways to keep it.
Japanese Patent No. 2809387 Japanese Utility Model Publication No.59-57260 JP 2004-230986 A

  As a result of earnest research, the present invention has been focused on the fact that the brakes of recent automobiles are equipped with a booster mechanism, and therefore a brake booster is provided at the back of the brake arm. This is what I came up with.

Under the above problems, the present invention provides a driver's seat via an operation cable comprising an inner wire and an arter cable by stepping on an auxiliary brake pedal provided in an auxiliary brake mechanism placed on the floor of the passenger seat. In the auxiliary brake device for an automobile that causes the brake arm provided in the vehicle to perform a predetermined pushing operation, one end of the outer cable is fixed to the auxiliary brake mechanism side, one end of the inner wire is connected to the auxiliary brake pedal, and the other end of the outer cable is connected to the auxiliary brake mechanism. The front end of the holder attached to the brake arm is linked to the lower end of the pushing plate that is pivotally attached to the pin provided on the upper part of the upper extending plate and extends downward, and the other end of the inner wire is On the right side of the brake booster looking into the front side behind the brake arm It is obtained by providing an auxiliary brake of a motor vehicle, characterized in that fixed to hanger down fixed with two set screws of the right side of the brake arm.

Further, in this, means for connecting the bracket to the hanger so as to be adjustable vertically and horizontally, and holding the inner wire by the bracket, and the brake booster set screw described in claim 3 depending on the vehicle type 5. A means for selecting and attaching joint bolts set at various heights, and fixing the hanger with the joint bolts. When the brake arm according to claim 4 is pushed in, the holder and the extension plate rotate around the pins. moves forward with the dynamic, coordinated part of the outer cable of the push plate provides a means remains in place.

  According to the invention of claim 1, since the brake booster is generally provided directly opposite to the brake arm, if the hanger is fastened using the bolt on the right side, the hanger descends on the right side of the brake arm. come. Therefore, the shape of the hanger is simple, and even if the operation cable is stopped on the hanger, deformation or the like hardly occurs, and the operation cable can be firmly held.

  Further, since the bolt on the right side of the brake booster is relatively exposed, the hanger can be easily attached. In addition, if the operation cable is a double cable consisting of an inner cable and an outer cable, a single cable is sufficient, and the structure of the members on the brake arm side is such that the holder for the outer cable including the holder is located upward from the middle of the brake arm. It will not get in the way when the brake arm is depressed.

  Furthermore, according to the means of claim 2, the vertical and horizontal positions of the bracket for stopping the operation cable can be adjusted, and according to the invention of claim 3, the front and back positions of the hanger can be adjusted by selecting the joint bolt. According to the fourth aspect of the present invention, the brake arm does not become heavy when the brake arm is depressed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The auxiliary brake device for an automobile according to the present invention includes an auxiliary brake mechanism A provided in the passenger seat and a brake operating mechanism B provided to act on the brake arm of the driver seat. 1 is a side view of the auxiliary brake mechanism A, FIG. 2 is a plan view, and FIG. 3 is a cross-sectional view taken along the line AA in FIG. 1. The auxiliary brake mechanism A is a frame 1 placed on the floor on the passenger seat side. And an auxiliary brake arm 2 that can be stepped on the frame 1.

  The frame 1 includes a base 3 that is framed in a front-rear E-shape with a pipe or the like, and an upright portion 4 that is raised obliquely rearward from the front portion of the base 3. The auxiliary brake arm 2 has a front arm 5 and a pedal arm 6 formed in a bifurcated shape from the upper base to the front and rear in a side view. 7 is provided so as to be rotatable in a vertical plane. A front block 9 to which one end of an inner wire 8a constituting the operation cable 8 of this example is fixed is rotatably provided at the lower end of the front arm 5.

  Behind the front block 9 is provided a rear block 11 fixed to a support shaft 10 provided laterally on the vertical member 3 a of the base 3, and one end of the outer cable 8 b is fixed to the rear block 11. . The front block 9 can rotate with respect to the support shaft 7 when the auxiliary brake arm 2 is stepped on, the front block 9 rotates forward about the rotation shaft 7 and is fixed thereto. The inner wire 8a is pulled out from the outer cable 8b. At this time, the inner wire 8a and the outer cable 8b are linearly extended so that the inner wire 8a and the outer cable 8b can slide smoothly. .

  An auxiliary brake pedal 12 on which a foot can be placed is provided at the rear end of the pedal arm 6. Further, a footrest arm 14 provided with a footrest 13 is fixed to the rear lateral member 3b (3c is a front lateral member) of the base 3. At this time, the footrest 13 is provided at a position slightly away from the right side of the auxiliary brake pedal 12 (when it is placed on the driver's seat or the passenger seat, the same applies hereinafter). The footrest 13 is used to place a foot when the auxiliary brake pedal 12 is not depressed. Further, a cable suspension 15 is provided on the rear lateral member 3 b of the base 3, and the operation cable 8 is suspended by a clip 16 or the like. Since the operation cable 8 is connected to the brake operation mechanism B provided in the driver's seat, this prevents the operation cable 8 from clogging the floor and interfering with driving.

  The base 3 is placed on a mat 17 that is set so as not to move on the floor. The mat 17 in this example includes a part of the vertical member 3a and the rear and front horizontal members 3b and 3c. A groove 18 into which is fitted is formed. If the base 3 moves when the auxiliary brake pedal 12 is depressed, it may not be able to be sufficiently depressed, which is prevented.

  4 is a side view of the brake operating mechanism B, FIG. 5 is a plan view, FIG. 6 is a cross-sectional view taken along line BB of FIG. 4, and FIG. 7 is a rear view of the bracket. The hanger 20 is fixed to the back of the arm 19 and fixes the other end of the inner wire 8a, and the brake mechanism 21 is attached to the brake arm 19 and fixes the other end of the outer cable 8b. Of these, the hanger 20 is fixed to a set screw 23 of a brake booster 22 constituting a servo mechanism of the brake. The brake booster 22 is provided in the engine room, and an operating rod 22 a projects from the front surface (toward the rear) and is pivotally attached to the brake arm 19. The front face is usually provided with four set screws 23, which are fastened and fixed by nuts 25 through a dashboard 24 or the like.

  The hanger 20 is integrally formed with the plate body hanging down on the right side of the mounting portion 20a through which the set screw 23 is inserted, and a nut fitted to the upper and lower set screws 23 on the right side of the brake booster 22. 25 is removed, and the hole formed in the mounting portion 20a is passed through the set screw 23 and tightened with the nut 25 to be fixed. It should be noted that the two screws on the right and top sides of the set screw 23 are selected because this position corresponds to the right side of the brake arm 19, and even if the hanger 20 is straightened, it is lowered to the right side of the brake arm 19 as it is. This is because it is relatively exposed and the operation of attaching and removing the nut 25 is easy.

  In this case, it is desirable to pass the hanger 20 while leaving the nut 25 as it is. However, since the recent set screw 23 does not have much protrusion from the nut 25, the allowance is often insufficient as it is. Therefore, the nut 25 is removed and the hanger 20 is attached, but this may be performed directly, but more preferably, a female screw 26a that can be screwed into the set screw 23 is formed, and a male screw 26b is provided at the tip. The projecting bolt 26 is used. If the nut 25 is removed or the hanger 20 is passed, the screw portion of the set screw 23 may be damaged. Therefore, this is prevented by changing the length S of the cylindrical portion 26c on which the female screw 26a is formed. This is because the front and rear mounting positions of the hanger 20 can be adjusted.

  In this example, a bracket 27 is provided below the hanger 20, and the inner wire 8 a is fixed to the bracket 27. This connection has a structure in which a bolt 28 is implanted in the bracket 27 and is passed through a hole 29 formed in the hanger 20 and both sides are tightened with nuts 28a, but by making the hole 29 a long hole, The vertical position of the bracket 27 can be adjusted. Moreover, the left-right position of the bracket 27 can also be adjusted by adjusting the nut 28a. As a result, the fixing point of the inner wire 8a can be adjusted in the front-rear direction and the vertical direction, and can be adapted to various vehicle types. Further, a block 30 is rotatably attached to the lower left end of the bracket 27, and the inner wire 8 a is fastened to the block 30. That is, a threaded portion 8 c is formed at the end of the inner wire 8 a, and the threaded portion 8 c is passed through the block 30 and both are tightened with a nut 31. Therefore, by adjusting the nut 31, the length between the fixed end of the block 30 and the fixed end of an outer cable 8b described later can be adjusted. This is also for adapting to various types of vehicles.

  The brake mechanism 21 that links the other end of the outer cable 8b to the brake arm 19 is configured as follows. First, the holder 32 is attached near or above the middle of the brake arm 19. The holder 32 has a quadrangular shape with a partially cut section, and the brake arm 19 is taken in at the cut portion. Since the right and left sides of the brake arm 19 of the holder 32 are provided with a thumbscrew 33, the holder 32 is fixed to the brake arm 19 by tightening the thumbscrew 33 after being taken in. This fixing is important, and if it is loosened, it may lead to an accident. In addition, it may be tightened more strongly with a sword screw or the like (not shown). The thumbscrew 33 is used because the holder 32 is attached to the brake arm 19 which is an equipment, and thus the use of a spanner or the like that may be modified is eliminated.

  An upper extension plate 34 is attached to the front side of the holder 32. The upper extending plate 34 has a contact portion 34a extending left and right at the lower end, a plate body 34b extending upward at the left end of the contact portion 34a, and extending backward from the back side (front surface) of the contact portion 34a. An extending screw portion 34c is formed. Therefore, the screw portion 34c is set to a predetermined length through a screw hole formed on the right side surface of the holder 32 (35 is a locking nut). Since the brake arm 19 is generally curved leftward on the front side, the holder 32 attached in the middle of the brake arm 19 is also inclined to the right according to the brake arm 19. However, the screw 34c is straightened to hold the plate body 34b. It is suitable to extend vertically.

  A pin 36 is passed through the upper part of the plate body 34b to the left and right, and a pushing plate 37 that is rotatably fitted to the pin 36 is provided along the right side of the plate body 34b. The push-in plate 37 is in contact with the front side of the contact portion 34a of the upper extension plate 34 and extends downward beyond this, and the outer cable 8b is fixed to the lower end thereof. Even in this case, the pushing plate 37 is located above and sufficiently behind the brake pedal 38 of the brake arm 19 so as not to interfere with the depression operation of the brake pedal 38. In particular, there is an accelerator pedal (not shown) on the right side of the brake pedal 38, and there should be no trouble when switching from the accelerator pedal to the brake pedal 38.

  In short, the present invention attaches the hanger 20 using the two upper and lower set screws 23 on the right side of the brake booster 22 and lowers the hanger 20 to the right side of the brake arm 19 to brake the hanger 20 or the bracket 27 connected thereto. The attachment of the mechanism 21 makes the shape and structure of each member simple (compact) and makes the attachment operation easy. In order to prevent the brake mechanism 21 from changing between the brake arm 19 and the accelerator pedal, the holder 32 is attached near the middle of the brake arm 19 or above it. By extending the extending plate 34 and the pushing plate 37 upward from this, the concern is wiped out.

  The outer cable 8b is fixed to the push plate 37 by rotatably attaching a block 39 to the push plate 37 and fixing the other end of the outer cable 8b to the block 39. The reason why the two blocks 30 and 39 of the bracket 27 and the push-in plate 37 in which the inner wire 8a and the outer cable 8b extend from each other can be rotated together is to extend the inner wire 8a and the outer cable 8b straightly. It is. Further, the lengths of the bolts 28 of the bracket 27 are adjusted to match the left and right positions of the two blocks 30 and 39. Both are for ensuring smooth sliding of the inner wire 8a and the outer cable 8b. In addition, a cable suspension 15 for suspending the outer cable 8b with a clip 16 or the like is also provided on the brake operating mechanism B side on this side.

  As described above, when the auxiliary brake pedal 12 is depressed on the passenger seat side, one end of the inner wire 8a is pulled out from one end of the outer cable 8b. At this time, if the operation cable 8 is bent, even if the other end of the inner wire 8a is fixed, the outer cable 8b is pushed to the other end side. The abutting portion 34a of 34 is pushed to the holder 32, and the brake arm 19 is pushed in to apply the brake. At this time, the stepping force of the auxiliary brake arm 2 and the stepping force of the brake arm 19 are not so different by adjusting the length of the auxiliary brake arm 2 according to the length of the brake arm 19 until the holder 32 is attached. It is preferable to do so. On the other hand, when the brake pedal 38 is depressed and the brake arm 19 is depressed, the original brake operation can be performed. At this time, only the portions of the upper plate 34 and the pin 36 of the pushing plate 37 move together with the brake arm 19, and the block 39 (the fixing point of the outer cable 8b) of the pushing plate 37 remains in place. Therefore, the operation load is not increased.

  By the way, the above is a case of an AT vehicle, but this brake operation mechanism B can also be applied to an MT (manual transmission) vehicle. In the case of an MT vehicle, a clutch pedal is provided on the left side of the brake arm 19 and the distance between the clutch pedal and the brake arm 19 is set to be relatively narrow. Therefore, the hanger 20 (bracket 27) is attached to the brake arm 19. If the brake mechanism 21 is lowered to the left side, the brake mechanism 21 interferes with the clutch arm and cannot be attached. However, when the hanger 20 is lowered to the right side of the brake arm 19 as described above, this is not the case.
