Description

[Detailed description of the invention] The present invention is a tilt steering device for a vehicle, in particular, once the driver adjusts the tilt angle to an arbitrary optimal position, even if the driver flips up the steering wheel for convenience when getting on or off the vehicle, the tilt steering device can be used again. This invention relates to a so-called tilt steering device with a memory mechanism that allows the steering wheel to return to its original position simply by pulling it down when riding a vehicle.

Generally, tilt steering devices can be roughly divided into two types depending on the adjustment method. One is a type that allows stepless adjustment, and the other is a type that features stepless adjustment. Each type has its advantages and disadvantages, and it cannot be generalized, but the former allows fine adjustment in principle, but in reality, when the lock is released for adjustment, it immediately moves from its initial position. Because of this, it is difficult to make fine adjustments when one wishes to make adjustments upward or downward by a certain amount from a certain setting position, and even if one wishes to make subtle adjustments, it is inconvenient. In order to solve these problems, the latter type of tilt steering device was devised in order to make the adjustment extremely easy by providing a sense of moderation in each step, and it has been well received by users for a long time. has been used. Moreover,
Many drivers do this in order to avoid the hassle of getting in and out of a vehicle due to interference between the lower end of the grip of the steering wheel and the driver's knees, or in order to avoid the hassle of getting in and out of a vehicle by being careful not to interfere. The steering wheel is used by flipping up the steering wheel (hereinafter sometimes referred to as tilt-away) by operating a manual lever, getting out of the vehicle, and adjusting it to the desired position of the driver after getting back in the vehicle. Ease of use was very important. In other words, rather than having the same driver frequently make different position adjustments, the driver may make tilt adjustments several times a day in order to find the same adjustment position. Therefore, although the above-mentioned device is easy to adjust, it is still inconvenient because it requires readjustment.

The present invention was developed to eliminate the inconvenience mentioned above.The purpose of this invention is that once the driver adjusts the steering wheel to the specified position, it is difficult to get on and off even if the driver flips up the steering wheel when getting out of the car. To provide a so-called tilt steering device with a memory mechanism, which automatically returns to the predetermined position and is securely locked at the same time by simply pulling the steering wheel downward when riding the vehicle again.

As clearly shown in FIGS. 2 and 3, the storage mechanism D is provided inside the aforementioned reinforcing plate 90 on the left side of both brackets 32 and 38, and as shown in FIGS. 8 and 9. It consists of the second manual lever 96 shown and a leaf spring 98 fixed thereto using rivets 97. A second manual lever 96 is disposed between the plate 39 and the first manual lever 92 and is mounted on the outer bearing portion of the bush 88. An operating knob 96a is provided at the upper end of the second manual lever 96, and the operating knob 96a is bent outward to form an arcuate elongated hole 102b provided in the column cover 102 (see FIGS. 1 and 3). (see). On the other hand, the lower end of the second manual lever 96 is provided with an arc-shaped shielding part 96b that closely covers a part of the sector gear 39a, and a locking claw 96c formed in a part of the shielding part 96b. , the locking pawl 96c is releasably engaged with one of the sector gears 39a. Further, in the center of the second manual lever 96, there is a long hole 96d whose long diameter direction is approximately the line connecting the operating knob 96a and the locking claw 96c.

a, 98a, the arcuate end surface 39c of the plate 39
resiliently and slidably abuts on. With this configuration, in this storage mechanism D, the leaf spring 9
The second manual lever 96 is pushed upward by the urging force of 8, and the locking pawl 96c engages the sector gear 39.
It is engaged with one of a. Further, in the state shown in FIG. 2, the lower end of the shielding part 96b and the pole 5
The upper ends of the second tooth portions 52a are in contact with each other.

In this embodiment configured as described above, when both the manual levers 92 and 96 are in the position shown in FIG. 2 and the fixing device C is in the locked state, the first manual lever 92 100 in the clockwise direction in the drawing, the roller 106 presses against the back of the pawl 52 and reliably maintains the meshing state between the teeth 52a of the pawl 52 and the sector gear 39a of the plate 39. As a result, the rotation bracket 38 is fixed at that position, and the third steering shaft 1 is pivotally supported by the third column tube 28 fixed to the rotation bracket 38.
6 is held at a predetermined angle of inclination. As a result, the steering wheel 22 is positioned and fixed at a predetermined position.

By the way, for the convenience of the driver when getting out of the vehicle, etc., the steering wheel 22 can be flipped upwards with just one touch of the first manual lever 92, and when getting back on the vehicle, the driver can simply pull the steering wheel 22 down. The operation of returning to a previously set predetermined angular position without requiring any adjustment operation only by operation and reliably fixing at that position will be described below.

As shown in FIGS. 2 and 10, if the first manual lever 92 is swung by its knob 92c in the counterclockwise direction (upward) as shown in the figure against the action of the return spring 100, the manual lever As the lever 92 swings, the roller 106 separates from the back of the pawl 52, and then the cam surface _92d1 of the cam hole 92d of the manual lever 92 engages the release pin 108 of the pawl 52.
and pushes the release pin 108 clockwise in the drawing. Therefore, the pawl 52 rotates clockwise in the figure, and the tooth portion 52a of the pawl 52 and the plate 39
The sector gear 39a is disengaged. Then,
A pair of tension springs 35, 3 interposed between the fixed bracket 32 and the rotating bracket 38.
5, the rotating bracket 38 tends to tilt away. At this time, the first manual lever 9
2 is released, the manual lever 92 is rotated clockwise by the return spring 100, and the roller 106 is pressed against the back of the pawl 52 again, causing the pawl 52 to rotate counterclockwise as shown in the figure and mesh with the sector gear 39a of the plate 39. However, since the shielding portion 96b of the second manual lever 96, which is engaged with the sector gear 39a by the locking claw 96c and is integrated with the plate 39, covers and hides the sector gear 39a of the plate 39, the pole 52 The tooth portion 52a only slides on the outer peripheral surface of the shielding portion 96b and does not mesh with the sector gear 39a. That is, the first manual lever 92 cannot return to the second locked state and is stopped in the middle. Therefore, the right arm portion 3 of the rotation bracket 38 is moved counterclockwise in the drawing by the action of the tension springs 35, 35.
The stopper bolt 64 fixed to the free end of the fixing bracket 32 rotates until it hits the lower end of the long hole 32a formed in the right arm 32R of the fixing bracket 32. That is, the third column tube 28 fixed to the rotation bracket 38, the third steering shaft 16 rotatably supported by the third column tube 28, and the steering wheel 22 fixed to the third steering shaft 16 are connected to both coupling means. A, B and the universal joint 14 located on their axes are tilted to the top (tilt away). (In the above explanation, the first manual lever 92 is released during the tilt-away operation, but if the first manual lever 92 is released after the tilt-away operation is completed, the pole 52
The tooth portion 52a can be tilted away without slidingly contacting the outer peripheral surface of the shielding portion 96b. ) In this way, tilt-away can be performed extremely easily by simply operating the first manual lever 92 with one touch, and not only the tilt-away but also the ease of getting on and off the vehicle for the driver are significantly improved.

In the above-mentioned tilted away state, as clearly shown in FIG.
Since the pole a is pressed, the pole 52 is
It is not possible to rotate any further counterclockwise from the position shown in FIG. The steering wheel 22, which is connected to the steering wheel 22, is not fixed and held in an upwardly raised state. Therefore steering wheel 2
If you pull down 2, you can easily move it down.

Now, if the driver pulls down the steering wheel 22 against the spring action of the tension springs 35, 35 when re-boarding the vehicle, etc., the rotating bracket 38 is not fixed as described above, so it can easily be moved downward (clockwise). ), and when it comes to the position rotated by exactly the same angle as the tilted angle during tilt-away, the outer peripheral surface of the shielding part 96b of the second manual lever 96, which is moving integrally with the plate 39, and the pole 52. The engagement (sliding contact) with the tooth portion 52a is disengaged,
The pole 52 is now movable toward the sector gear 39a of the plate 39. In this state, the roller 106 pushes the back of the pole 52 again due to the spring action of the return spring 100, and the pole 5
2 in the counterclockwise direction shown in the figure. Since the angle of downward rotation is equal to the angle of flip-up, the teeth 52a of the pole 52 and the sector gear 39a of the plate 39 will mesh with each other at exactly the same peaks and valleys as before, so that The steering wheel 22 is securely fixed at the predetermined position and can be returned to the predetermined position by simply pulling down the steering wheel 22. It goes without saying that the first manual lever 92 is automatically returned to its original position (the position shown by the imaginary line in FIG. 10 and the solid line in FIG. 2) and fixed at this point.

Next, a case where the driver adjusts the position of the steering wheel 22 according to the physique of the driver will be explained based on FIGS. 2 and 11. The position of manual lever 92 in FIG. 2 shows the released (non-operated) condition, ie, the pivot bracket 38 is fixed relative to the fixed bracket 32, which is shown in phantom in FIG. First, as shown in FIG. 11, push the second manual lever 96 with its operating knob 96a in the direction of arrow 1 (downward) against the action of the leaf spring 98, and first push the locking pawl 96c onto the plate. After being separated from the sector gear 39a of the plate 39, the shielding part 96b is separated from the sector gear 39a of the plate 39 by rotating in the direction of arrow 2 (clockwise) in the figure. Although not shown in FIG. 11, the rotation angle of the second manual lever 96 is determined by a locking portion of some kind, so that the locking pawl 96c is connected to the sector gear 39a.
It goes without saying that it is better to take care not to completely separate from the person. In any case, after moving the second manual lever 96 to the position shown in FIG. 11, if the first manual lever 92 is swung counterclockwise (upward) as shown in the figure, the The pole 52 is separated from the sector gear 39a of the plate 39 in accordance with this order. That is, at this point, the rotating bracket 38, the third column tube 28 fixed to the rotating bracket 38, the third steering shaft 16 rotatably supported by the third column tube 28, and the third steering shaft 16 are The fixed steering wheel 22 has a pole 52 and a pole 5.
2 is pivotally supported by the fixed bracket 32, it is free to rotate either clockwise or counterclockwise in the drawing. Therefore, in this state, if the driver adjusts the steering wheel 22 upward or downward by an arbitrary angle, the desired angle of inclination can be obtained.

The driver moves the spring wheel 22 to the desired angle.
When the first manual lever 92 is released after moving the return spring 100 in the reverse order as described above,
The roller 106 moves again to the pole 52 due to the spring action of
Push the back of the pawl 52 in the clockwise direction shown in the figure, and the teeth 52a of the pawl 52 mesh with the sector gear 39a of the plate 39, and the rotating bracket 38
is again fixed to the fixed bracket 32. After that, turn the operation knob 96a of the second manual lever 96 into the 11th position.
While pushing in the direction of the arrow 1 shown in the illustration,
When the operation knob 96a is released after swinging in the direction (counterclockwise) until the lower end of the shielding part 96b of the second manual lever 96 comes into contact with the upper end of the toothed part 52a of the pawl 52, the action of the leaf spring 98 The locking claw 96c is engaged with the sector gear 39a of the plate 39 again. That is, the plate 39 and the second manual lever 96 become integrated again, but at this time, the locking claw 96c of the second manual lever 96 and the plate 3
The peaks and valleys at which the sector gear 39a of No. 9 meshes are determined by the relative deviation between the pole 52 and the sector gear 39a, that is, by the inclination arbitrarily adjusted by the driver (more precisely, by the inclination of the teeth close to the inclination arbitrarily adjusted by the driver). The mesh is shifted by the same amount as the pitch angle). This means that
This means that the storage mechanism D has been set again to the arbitrary set tilt angle position. Also, at this time, the position of the first manual lever 92, the position of the second manual lever 96, the position of the pawl 52, etc. completely return to the state shown in FIG. 2, and only the rotating bracket 38 and the third column tube 28, third steering shaft 16, steering wheel 22
etc. are fixed in a tilted state by a desired angle of inclination, and the adjustment operation is completed. The tilt-away operation and readjustment operation after adjustment can be performed in exactly the same manner as described above.

As detailed above, in the present invention, as exemplified in the above embodiment, the fixed bracket 32 is fixed to a part of the vehicle body (pedal bracket 36) below the instrument panel 34, and the tiltable steering wheel. The fixed bracket 3 is fixed to a column tube 28 that rotatably supports the shaft 16 and the steering wheel 22.
2, a rotating bracket 38 is connected to the rotating bracket 38 so as to be able to freely rotate by a required angle in the vertical direction, and the rotating bracket 38 is interposed between the rotating bracket 38 and the fixed bracket 32, and urges the rotating bracket 38 to flip upward. A pawl 52 is attached to the first spring means 35, 35 and one side of the fixed bracket 32 so as to be rotatable in the vertical direction, and releasably meshes with a sector gear 39a formed at the free end of the rotary bracket 38.
, a first manual lever 92 that is coaxially and rotatably assembled in the vertical direction on the pivot shafts (connection means B) of both the brackets 32 and 38 and is operatively linked with the pawl 52; A stopper is provided integrally with the manual lever 92 and releasably engages with the back of the pawl 52 to restrict swinging of the pawl 52 and maintain engagement between the tooth portion 52a of the pawl and the sector gear 39a. roller 106);
This stopper (roller 106) is
the first manual lever 92 for engaging the back of the second
and second spring means 100 for biasing the
When the first manual lever 92 is not operated, the rotary bracket 38 is fixed at a predetermined inclination angle with respect to the fixed bracket 32 due to the engagement between the teeth 52a of the pole and the sector gear 39a, and the first manual lever 92 is not operated. The lever 92 is connected to the second spring means 1.
00, the stopper (roller 106) and the pawl 52 are disengaged, and the teeth 52a of the pawl are disengaged from the sector gear 39a, and the rotating bracket 38 is disengaged from the pawl 52.
In the tilt steering device for a vehicle, in which the lever is flipped upward by the action of the first spring means 35, the pivot shaft (connection means B) of the brackets 32 and 38 is tilted upwardly and downwardly on one side of the sector gear 39a. The sector gear 39a is assembled so as to be rotatable to the axis and slidable in a direction perpendicular to the axis of the pivot.
A locking claw 96c that releasably engages with a portion of the sector gear 39a and an arcuate shielding portion 9 that covers a portion of the sector gear 39a.
6b, and a third spring 98 that biases the second manual lever 96 in the direction in which the locking pawl 96c engages with the sector gear 39a, as described above. Even if the operation of the first manual lever 92 is released when the rotation bracket 38 is flipped upward, the second
The shielding portion 96b of the manual lever 96 prevents the pawl teeth 52a from meshing with the sector gear 39a, and in this state, simply pulling down the steering wheel 22 causes the pawl teeth 52a and the sector gear 39a to engage. The second manual lever 96 is pushed and swung to disengage the locking pawl 96c from the sector gear 39a, and the first A feature is that the angle of inclination of the rotating bracket 38 with respect to the fixed bracket 32 can be adjusted by swinging the manual lever 92. Therefore, according to the present invention, even if the steering wheel is flipped upwards by one-touch lever operation for convenience when getting on and off after being adjusted to a predetermined position, it can be easily adjusted by simply pulling the steering wheel downwards. The steering device can be returned to the position before being flipped upward and securely fixed at that position, and the usability of the steering device can be greatly improved.

Furthermore, the present invention can be implemented by effectively utilizing the existing configuration of the sector gear 39a and simply adding two members, the second manual lever 96 and the third spring means 98. Therefore, it is possible to expect the effect of being able to be implemented at low cost, and since the second manual lever 96 is elastically fixed by the third spring means 98, the vehicle There is no fixation failure of the second manual lever 96 due to the vibration of the lever, and the position of the second manual lever 96 can be adjusted by pushing the same lever 96 against the third spring means 98. This can be done by rotating the lever 96 around its axis with the locking claw 96c removed from the sector gear 39a, and then returning the lever 96, and can be easily performed with one hand. The quality is extremely good.

Claims (1)

[Scope of utility model registration request] A fixed bracket is fixed to a part of the vehicle body below the instrument panel, and a column tube that rotatably supports a tiltable steering shaft and steering wheel is fixed to the fixed bracket. a rotary bracket movably connected; a first spring means interposed between the rotary bracket and the fixed bracket for biasing the rotary bracket upward; and one of the fixed brackets; A pole is attached to a side surface so as to be rotatable in the vertical direction and releasably meshes with a sector gear formed at the free end of the rotating bracket, and a pole is assembled coaxially with the pivot axis of both the brackets and rotatable in the vertical direction. a first manual lever that is attached to the pole and operatively interlocks with the pole; and a first manual lever that is integrally provided with the first manual lever and releasably engages with the back of the pole to restrict swinging of the pole. a stopper that maintains engagement between the teeth of the pawl and the sector gear; and a second spring stage that biases the first manual lever to engage the stopper with the back of the pawl; When the first manual lever is not operated, the rotary bracket is fixed at a predetermined inclination angle with respect to the fixed bracket due to the engagement between the teeth of the pole and the sector gear, and the first manual lever is not operated when the first manual lever is not operated. When the set angle is oscillated against the spring means, the stopper and the pawl are disengaged, and the teeth of the pawl and the sector gear are disengaged, so that the rotating bracket moves to the first spring means. In the tilt steering device for a vehicle, which is capable of being flipped upward by action, the sector gear is mounted on one side of the sector gear to be rotatable in the vertical direction and slidable in the direction perpendicular to the axis of the pivot shafts. a second manual lever having a locking pawl that releasably engages with a portion of the sector gear and an arcuate shielding portion that covers a portion of the sector gear; and a direction in which the locking pawl engages with the sector gear. A third spring is provided that biases the second manual lever so that when the rotating bracket is flipped upward as described above, even if the first manual lever is released, the second manual lever is not activated. The shielding part of the manual lever prevents the teeth of the pawl from engaging with the sector gear, and in this state, simply pulling the steering wheel downward will prevent the teeth of the pawl and the sector gear from jumping upwards. by pushing and swinging the second manual lever to disengage the locking pawl from the sector gear, and by swinging the first manual lever. A tilt steering device for a vehicle, characterized in that the angle of inclination of the rotating bracket with respect to the fixed bracket can be adjusted.
