On the right side of the head (32) of the bolt (22), a convex part (32a) is formed that fits on both front and rear edges of the long hole (25) formed in the inverted L-shaped attachment member (28). Yes. Thus, the bolt (22) does not rotate even if it moves in the vertical direction along the long hole.

  A substantially inverted U-shaped member (33) that couples the two inverted L-shaped attachment members (28) is provided on the inner front side of the horizontal upper wall (27) across the steering column (1).

  A bolt (22) inserted through the long hole (25) of the inverted L-shaped mounting member (28) is screwed with a nut (not shown) for fixing the vertical position of the square tube (24). . Further, the nut is attached to the upper end of the operation lever (34) that operates to fix or release the square tube (24).

  As shown in FIG. 1, when the operation lever (34) is rotated clockwise, the nut attached to the upper end of the operation lever (34) is loosened. The steering wheel (35) is adjusted to an appropriate height by moving the bolt (22) vertically along the elongated hole (25) of the reverse L-shaped mounting member (28) and moving the steering column (1) vertically. ) Can be moved. After the steering wheel (35) is moved to a predetermined height, the operation lever (34) is turned counterclockwise, whereby the nut attached to the upper end of the operation lever (34) is tightened, and the steering column ( 1) can be held in that position.

  Even when the bolt (22) is fixed to the top of the long hole (25), in order to push up the steering wheel (35) and operate the brake, the steering column (1) and the substantially inverted U-shaped member (33) A predetermined distance is required between them.

  The brake wire (8) is inserted into the tube (36), and the rear end of the tube (36) is fixed to the upper side of the peripheral surface of the steering column (1) with an L-shaped support bracket (37). The front end is fixed to the upper partition wall (4) with an L-shaped support fitting (38).

  As shown in FIGS. 3 to 5, wheels (39) and (40) are formed at the front and rear ends of the brake wire (8). The lower side of the brake plate (7) is divided into left and right sides and formed into two forks. Between the two forks, the front end ring (39) of the brake wire (8) is fitted. A through hole (41) is formed below the brake plate (7), and the brake plate (7) and the clevis (14) are attached by pins (42). A snap pin (43) that prevents the pin (42) from coming off is attached to the pin (42). The rear wheel (40) of the brake wire (8) is fitted in the center of the pin (31) to which the second roller (13) is attached.

  As shown in FIGS. 3 and 4, a vertical hole (44) is formed in the lower wall of the square tube (24), and the bolt (45) is passed therethrough. A square-shaped protrusion (47) is formed below the head (46) of the bolt (45).

  The steering column (1) has a space in the lower part of the peripheral surface for inserting a rectangular through hole (48) fitted to the convex part (47) of the bolt (45) and the head (46) of the bolt (45). A substantially concave holding member (50) having a flange (49) formed along the lower peripheral surface of the column (1) is welded.

  The welding between the flange (49) of the substantially concave holding member (50) and the lower part of the central peripheral surface of the steering column (1) is achieved by the projecting portion (47) of the bolt (45) and the through hole of the substantially concave holding member (50) ( 48) and the bolt (45) passes through the vertical through hole (44) formed in the square tube (24).

  The convex part (47) of the bolt (45) and the through hole (48) of the substantially concave holding member (50) are fitted together, and the substantially concave holding member (50) is welded to the lower peripheral surface of the steering column (1). This prevents the bolt (45) from rotating.

  A spring (51) is fitted on the bolt (45) that passes through the through hole (44) formed in the lower wall of the rectangular tube (24) and the through hole (48) of the substantially concave holding member (50). Yes. An insertion recess (52) into which the upper half of the spring (51) can be fitted is formed on the lower wall of the square tube (24).

  A spring receiver (54) having a screw hole in the vertical direction formed in the center via a washer (53) is screwed into the lower portion of the bolt (45), and further, a spring receiver (54) is located below the spring receiver (54). A nut (55) that prevents the nut from falling off is screwed together.

  To relatively increase the resistance of the force that pushes up the steering wheel (35) in accordance with the strong driver, rotate the spring receiver (54) and compress the spring (51) to increase the spring force. . On the other hand, in order to relatively weaken the resistance of the force that pushes up the steering wheel (35) in accordance with the driver with weak force, the spring receiver (54) is counter-rotated and the spring (51) is distracted, To weaken.

  As shown in FIG. 5 and FIG. 6, the actuating lever (21) is composed of two plates having a quadrangle in a side view and an upper corner having an inverted V shape, and is swingably fitted to the shaft (20). ing.

  A screw rod (15) fitted with a push spring (56) is inserted through a through hole (16) of a pin (17) attached to the upper part of the operating lever (21). A snap pin (57) that prevents the pin (17) from coming off is attached to the pin (17). A nut (58) is screwed onto the screw rod (15) that penetrates the pin (17). As a result, the pin (17) attached to the upper part of the operating lever (21) and the screw rod (15) can slide. The spring force of the push spring (56) fitted to the screw rod (15) is weaker than the spring force of the tension spring (10).

  As shown in FIGS. 6 and 7, the upper side of the brake lever (60) to which the brake pedal (59) is attached at the lower end is sandwiched between the operating lever (21) from the left and right. The upper end of the brake lever (60) is pivotally attached to the center of the operating lever (21) by the shaft (20).

  A push rod (61) extends rearward from the brake pump (18), and a clevis (62) provided at the rear end of the push rod (61) is connected to the lower end of the operating lever (21) with a pin (63). It is attached.

  As shown by a two-dot chain line in FIG. 8, the other end of the rotation shaft (6) is fixed to the rotation shaft (6) and extends from the rotation shaft (6) obliquely downward to the front. The lower end of the plate (64) and the first accelerator plate (64) is pivotably attached to the lower end, and the pin (66) is attached to the lower part of the accelerator wire (65) extending in the front-rear direction. And a second accelerator plate (67).

  The left and right sides of the second accelerator plate (67) are divided into two forks. The upper side of the second accelerator plate (67) sandwiches the lower end of the first accelerator plate (64) and is attached to the first accelerator plate (64) with a pin (68). 67) The accelerator wire (65) is passed between the two forks formed on the lower side.

  The rear end of the accelerator wire (65) is attached to the upper end of an accelerator lever (70) to which an accelerator pedal (69) is attached. The front end of the accelerator wire (65) is connected to a throttle (not shown) of a throttle sensor that electrically detects the amount of depression of the accelerator pedal (69).

  Next, the operation of the emergency stop device for a vehicle according to the present invention will be described.

  In a state where the pushing-up force is not applied to the steering wheel (35), the first substantially H-shaped member (2) and the second substantially H-shaped member (3) are disposed on the brake plate (7 The brake wire (8) is pulled by the pulling spring (10) hung on the lower part of), and an inverted V-shape is formed with the connection point of both substantially H-shaped members (2) and (3) as the apex.

  If the driver depresses the accelerator pedal (69) due to a misrecognition of the brake pedal (59) and the vehicle suddenly starts, the driver is confused and cannot accurately depress the brake pedal (59), reflecting his arm. Take a posture to stretch and stretch. As a result, the driver pushes up the steering wheel (35). Then, the steering column (1) moves upward with the front end of the steering column (1) as a fulcrum.

  When the steering column (1) moves upward, as shown in FIG. 4, the first roller (12) is pressed to the upper side of the inner surface of the square tube (24). Thereby, the reverse V-shape consisting of the first substantially H-shaped member (2) and the second substantially H-shaped member (3) becomes horizontal. Then, as the second roller (13) rotates rearward, the second substantially H-shaped member (3) pulls the brake wire (8) rearward. At this time, the brake wire (8) slides backward in the tube (36).

  When the brake wire (8) is pulled backward as shown by an arrow in FIG. 6, the brake lever (60) is stationary and the center of the operating lever (21) is shown as shown by a two-dot chain line in FIG. The upper side of the actuating lever (21) moves backward with the shaft (20) provided on the fulcrum as a fulcrum. As a result, the lower side of the operating lever (21) moves forward, the piston (not shown) in the brake pump (18) is pushed by the push rod (61), and the brake is operated. When the steering wheel (35) is lowered and the pushing force is no longer applied to the steering wheel (35), the brake plate (7) is returned to its original position by the tension spring (10), and the operating lever (21) is also restored to its original position. Return to position and brake is released.

  As shown by the solid line in FIG. 7, when the driver depresses the brake pedal (59) without pushing up the steering wheel (35) when driving the vehicle, the brake lever (60) is counterclockwise with the shaft (20) as a fulcrum. When rotating in the direction, the brake lever (60) pushes the pin (63) of the clevis (62) forward. Then, the push rod (61) pushes the piston (not shown) in the brake pump (18) to actuate the brake. At this time, simultaneously with the brake lever (60), the upper side of the operating lever (21) moves backward and the lower side moves forward with the shaft (20) attached to the center of the operating lever (21) as a fulcrum. The pin (17) and screw rod (15) attached to the upper end of the actuating lever (21) slide, so even if the actuating lever (21) is moved by stepping on the brake pedal (59), the screw rod (15 ) Will not move backwards. The spring force of the push spring (56) fitted to the screw rod (15) is greater than the spring force of the tension spring (10) spanned from the upper part of the front partition (9) to the lower part of the brake plate (7). Therefore, even if the actuating lever (21) moves, the brake plate (7) is not pushed and moved by the spring force of the pushing spring (56).

  When the driver removes his / her foot from the brake pedal (59), the operating lever (21) is returned to its original position by the spring force of the push spring (56) as shown by the two-dot chain line in the figure, and the push rod (61) and the brake lever (60) are also returned to their original positions.

  Next, in a state where the accelerator pedal (69) is depressed and the vehicle is accelerating, the steering wheel (35) is pushed upward, and the brake wire (8) is moved backward by the second substantially H-shaped member (3). When pulled, the brake plate (7) fixed to the rotating shaft (6) shown in FIG. 6 moves backward with the rotating shaft (6) as a fulcrum. As a result, the pivot shaft (6) pivots, and as shown by the solid line in FIG. 8, the first accelerator plate (64) fixed to the other end of the pivot shaft (6) is pivoted. Move backward and downward using (6) as a fulcrum. Then, the second accelerator plate (67) also moves rearward and lower, so that the force pulling the accelerator wire (65) of the second accelerator plate (67) upward is released. As a result, the force for opening the throttle of the accelerator wire (65) becomes weak, and acceleration of the vehicle can be prevented.

  Therefore, if the steering column (1) moves upward by applying a pushing force to the steering wheel (35), the vehicle will not accelerate even if the accelerator pedal (69) is depressed, and the brake wire (8) will be pulled. The brake can be activated.

  As described above, when a pushing force is applied to the steering wheel (35), the brake can be operated and the vehicle can be suddenly stopped without depressing the brake pedal (59).

  Note that the present invention can be applied to a vehicle with an automatic transmission or a vehicle without an automatic transmission.
