Abstract

<P>PROBLEM TO BE SOLVED: To eliminate a flutter when an operating lever held to a direction-indicating position of a vehicle by a moderating mechanism is returned by steering operation to the opposite direction of the direction indication of the vehicle; or to prevent the operating lever from reaching the opposite direction-indicating position. <P>SOLUTION: When the operating lever 2 is operated from the neutral position, a moderate plate 7 is biased to a moderate piece 6 and oscillated, and the angle of the moderate plate 7 relative to the moderate piece 6 is changed. Since the moderate plate 7 returns to the moderate trough-shaped part 9 of the neutral position and the ascending angle of the moderate chevron-shaped part 12 further ahead is made to be large by changing of the angle of the moderate plate 7 and by the resistance applied to the oscillation (return oscillation) of the moderate plate 7 with a resistance applying means, the progress of the moderate piece 6 is restricted. The operating lever 2 is prevented from further progressing or hardly progress even it reaches to the original position. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a vehicular direction indicating device in which an operation lever held at a direction indicating position of a vehicle is returned by a steering operation in a direction opposite to the instructed direction.

Conventionally, an operation lever is provided in the vicinity of a steering wheel in a vehicle, in particular, an automobile, and a user operates the operation lever to instruct the vehicle to turn left or right. The lever is held by the moderation mechanism at the neutral position and the direction indicating position of the right / left turn. The moderation mechanism is biased in the direction of the moderation peak portion and the moderation valley portion from the operation lever side, and the moderation valley portion formed alternately with a plurality of moderation peak portions on the body of the vehicle direction indicating device that supports the control lever. The moderation piece engages with the moderation trough, so that the operation lever is held at the neutral position and at the right / left turn direction indicating position. Then, the operation lever held at the direction indicating position is returned by a steering operation in a direction opposite to the instructed direction (see, for example, Patent Document 1).
Japanese Unexamined Patent Publication No. 7-320595

  However, when the operating lever held at the vehicle direction indication position by the moderation mechanism as described above is returned by the steering operation in the direction opposite to the instructed direction, the moderation piece causes the moderation piece to exceed the moderation peak. As a result, the control lever continues to move even if it reaches the source position (neutral position) by sliding down the slope rapidly with the given urging force and adding self-propelled energy due to the weight of the control lever. There is a possibility that the lever may flutter when the lever moves beyond the source position and then returns, or the opposite direction indication position is reached without returning to the opposite direction indication position.

  The present invention has been made in view of the above circumstances, and therefore the object thereof is to return the operation lever held at the vehicle direction indication position by the moderation mechanism by the steering operation in the direction opposite to the indicated direction. It is an object of the present invention to provide a vehicular direction indicating device that can eliminate fluttering of the operating lever or prevent the operating lever from reaching the opposite direction indicating position.

  In order to achieve the above object, a vehicle direction indicating device of the present invention includes an operation lever operated by a user, and a moderation mechanism that holds the operation lever at a neutral position, a right turn direction instruction position, and a left turn direction instruction position. The operation lever held at the right turn direction indication position and the left turn direction indication position is returned by a steering operation in a direction opposite to the indicated direction. It comprises a moderation plate having moderation valleys alternately with ridges, and a moderation piece urged from the operation lever side toward the moderation ridges and moderation valleys of the moderation plate, the moderation piece being the moderation valley and By engaging, the operation lever is held at the neutral position, the right turn direction instruction position, and the left turn direction instruction position, and the moderation plate is kept in the same direction as the operation direction of the operation lever. With swingably provided direction, characterized in that a resistance applying means for applying a resistance to the swinging of the detent plate.

  According to the above means, when the operation lever is operated from the neutral position, the moderation plate is swung by the moderation piece, and the angle of the moderation plate with respect to the moderation piece changes. By changing the angle of the moderation plate and applying resistance to the swinging (returning swinging) of the moderation plate by the resistance applying means, the operating lever held at the vehicle direction indication position is indicated by the moderation mechanism. When the steering operation is reversed in the opposite direction, the moderation piece returns to the neutral moderation valley, and the climbing angle of the previous moderation mountain increases and the progress of the moderation piece Is controlled. Thus, even if the operating lever reaches the source position, it will not be advanced or less. As a result, the operation lever does not flutter or does not reach the opposite direction indication position.

Hereinafter, an example (one embodiment) of the present invention will be described with reference to the drawings.
First, FIG. 2 shows the overall configuration of a direction indicator device for a vehicle, particularly an automobile, and the operation lever 2 is pivoted up and down around the shaft portion 3 on the body 1, especially the body main body 1a. I support it as possible. The body 1 includes the body main body 1a and the body cover 1b shown in FIGS. 3 and 4, and the body cover 1b is attached to the front surface of the body main body 1a (the front side in the direction perpendicular to the paper surface of FIG. 2). ing.

  On the other hand, the operation lever 2 includes a lever body 2 a and a bracket 2 b to which the lever body 2 a is attached. The bracket 2 b has the shaft portion 3. The operation lever 2 is operated up and down by the user on the lever body 2a side, and the downward operation is for instructing the vehicle to turn left and the upward operation is for instructing the vehicle to turn right.

  A hole 4 is formed in the bracket 2b on the side opposite to the lever body 2a side (the right side in FIG. 2). A compression coil spring 5 is accommodated in the hole 4, and the moderation piece 6 is placed at the tip of the spring 5. Is arranged. In this case, the moderation piece 6 has a bullet shape with a hemispherical tip.

  On the other hand, a moderation plate 7 is disposed on the body main body 1 a at a portion facing the moderation piece 6. This moderation plate 7 has moderation valley portions 8, 9, 10 arranged in the vertical direction on the moderation piece 6 side, and between the moderation valley portions 8, 9, 10 is a moderation mountain portion 11, 12. Accordingly, the moderation valley portions 8, 9, and 10 are alternately present with a plurality (in this case, two) of the moderation mountain portions 11 and 12. In particular, the slopes from the central moderation valley 9 to the moderation peaks 11 and 12 on both sides have the same gradient.

  Further, the moderation plate 7 supports and supports the central portion where the central moderation valley portion 9 exists on the body body 1a by the shaft portion 13 so as to be swingable. Here, the swinging direction of the moderation plate 7 is clockwise and counterclockwise, and the rotation direction (up and down) of the operation lever 2 is also clockwise and counterclockwise. The operation lever 2 is provided so as to be operable in the same direction.

  Thus, the moderation piece 6 is urged in the direction of the moderation valley portions 8, 9, 10 and the moderation mountain portions 11 and 12 by the elastic force of the spring 5, and one of the moderation valley portions (by the urging force ( In the example shown in FIG. 2, the moderation piece 6 is pressed and engaged with the central moderation valley portion 9), the moderation valley portions 8, 9, 10 and the moderation mountain portions 11 and 12, the moderation piece 6 and the spring 5 Thus, the moderation mechanism 14 is composed.

  And the convex parts 15 and 16 are formed in the front part of the up-and-down both ends of the moderation plate 7, As shown in FIG.3 and FIG.4, as shown in FIG.3 and FIG.4 in the inner surface part of the body cover 1b of the said body 1 Concave portions 17 and 18 are formed in which the projecting ends of the convex portions 15 and 16 are engaged.

  In addition, although not shown, the body body 1a of the body 1 is provided with a switch for instructing the vehicle to turn right or turn left in accordance with the operation of the operation lever 2, and the bracket. Although not shown in FIG. 2b, the ratchet 2b is provided with a ratchet which is a cancel receiving member. The tip of the ratchet protrudes outside the body body 1a (particularly leftward in FIG. 2), and a steering wheel (not shown) It is made to respond | correspond to the cancellation cam (this is not shown) which is the cancellation member rotated integrally.

Next, the operation of the above configuration will be described.
When the moderation piece 6 of the moderation mechanism 14 is in the state of FIG. 2 in which the moderation piece 6 is pressed and engaged with the central moderation valley 9 by the elastic force of the spring 5, the operation lever 2 is held in the neutral position.

  From this neutral position, when the user operates the operating lever 2 downward on the lever body 2a side, the operating lever 2 rotates counterclockwise about the shaft portion 3 of the bracket 2b as shown by the solid line in FIG. To do. At this time, in the moderation mechanism 14, the moderation piece 6 that has been engaged with the central moderation valley portion 9 climbs the slope portion that reaches the upper moderation mountain portion 11 and pushes the moderation plate 7 in the process. As shown in FIGS. 5 and 6, the pushed moderation plate 7 is rotated clockwise in FIG. 1 while the convex portions 15 and 16 are disengaged from the concave portions 17 and 18 of the body cover 1b and slidably contact the inner surface of the body cover 1b. The angle with respect to the moderation piece 6 is changed. Then, the moderation piece 6 beyond the moderation peak portion 11 moves to the upper moderation valley portion 8 and presses and engages with the moderation valley portion 8. As a result, the operation lever 2 is held at the left turn direction indicating position indicated by the solid line in FIG. Accordingly, in the body main body 1a, the switch for instructing the left turn direction of the vehicle responds and the left turn direction of the vehicle is instructed.

  On the other hand, when the user operates the operation lever 2 upward on the lever body 2a side from the neutral position, although not shown, the operation lever 2 rotates clockwise around the shaft portion 3 of the bracket 2b. At this time, in the moderation mechanism 14, the moderation piece 6 that has been engaged with the central moderation valley 9 climbs the slope reaching the moderation mountain 12 below and pushes the moderation plate 7 in the process. The pressed moderation plate 7 is not shown in the figure, but the convex portions 15 and 16 are separated from the concave portions 17 and 18 of the body cover 1b in the direction opposite to the above and are brought into sliding contact with the inner surface of the body cover 1b. The angle with respect to the moderating piece 6 is changed. Then, the moderation piece 6 beyond the moderation peak portion 12 moves to the moderation valley portion 10 below, and presses and engages the moderation valley portion 10. Thereby, the operation lever 2 is held at the right turn direction instruction position. Accordingly, in the body main body 1a, the switch for instructing the right turn direction of the vehicle responds, and the right turn direction of the vehicle is instructed.

  Now, when the operation lever 2 is held at the left turn direction indicating position or the right turn direction indicating position as described above, when the steering wheel is rotated in the direction opposite to the indicated direction, the steering lever is integrated with the steering wheel. The operating lever 2 is returned to the neutral position in response to the ratchet being operated by the cancel cam that rotates in the forward direction.

  At this time, the moderation piece 6 crosses the moderation peak 11 or the moderation peak 12 and maintains the biasing force applied by the spring 5 from the moderation peak 11 to the moderation valley 9 or moderation from the moderation peak 12. Although the slope angle to the valley 9 is slid down, the climb angle of the previous moderation mountain 12 or 11 which is going to return to the moderation valley 9 and still proceed is that the moderation plate 7 is swung by the operation of the previous operation lever 2 However, the angle is increased by changing the angle with respect to the moderation piece 6.

  In addition, at this time, the convex portions 15 and 16 are pressed against the inner surface of the body cover 1b to give resistance to the swing of the moderation plate 7, that is, the convex portions 15 and 16 are between the inner surface of the body cover 1b. Thus, it functions as a resistance applying means that gives resistance to the oscillation of the moderation plate 7. For this reason, the progress of the moderation piece 6 is controlled by the slope portion of the moderation mountain portion 12 or 11 where the climbing angle of the moderation plate 7 is increased, and thus the operation lever 2 is not advanced even when it reaches the source position. Or less. As a result, the operation lever 2 does not flutter or does not reach the opposite direction indication position.

  The moderation plate 7 receives the traveling force of the moderation piece 6 while restricting the progress of the moderation piece 6 by the resistance force caused by the protrusions 15 and 16 being pressed against the inner surface of the body cover 1b as described above. As a result, it is returned to the source position and is held at the source position by engaging the convex portions 15 and 16 with the concave portions 17 and 18 of the body cover 1b.

  As described above, in this configuration, the moderation mechanism 14 that holds the operation lever 2 at the neutral position, the right turn direction indication position, and the left turn direction indication position is provided with the moderation valley portions 8 and 9 alternately with the plurality of moderation mountain portions 11 and 12. , 10 and a moderation piece 6 urged in the direction of the moderation peak portions 11 and 12 and the moderation valley portions 8 to 10 of the moderation plate 7 from the operation lever 2 side. In addition to being provided so as to be able to swing in the same direction as the operating direction of the operating lever 2 and by providing resistance applying means for giving resistance to the swinging of the moderation plate 7, the moderation mechanism 14 is locked at the vehicle direction indication position. When the operation lever 2 is returned by the steering operation in the direction opposite to the direction instructed, the fluttering of the operation lever 2 can be eliminated or the operation lever 2 can reach the opposite direction indication position. And it can ensure that no can so as not to reverse direction indication will be made.
