Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tilting operation device for a tilt bundle in an automobile, and more particularly to a tilting operation device for a tilt bundle in which the tilting operation of the tilt bundle is performed by a foot pedal.

Conventionally, a tilting operation device for a tilt bundle of an automobile has been provided with a locking device for locking and unlocking the tilting of a steering bundle or a steering shaft to which the bundle is attached, and the locking device is linked with a foot-operated pedal. It is well known that a tilt bundle is tilted by pressing a foot pedal.

By the way, conventionally, with such a tilting operation device for a tilt bundle that is operated by a foot pedal, there is a possibility that when driving a car, the driver mistakenly presses the foot pedal for an accelerator pedal, clutch pedal, brake pedal, etc. ,
Alternatively, in order to prevent the driver from accidentally touching the foot pedal or other erroneous operations, the foot pedal may be placed at a higher position than the accelerator pedal, etc. Efforts are made to prevent erroneous operations.

However, although this conventional positioning of the foot pedal is good in terms of preventing erroneous tilt operations,
On the other hand, the foot pedal is difficult for the driver to see as it is hidden behind the vehicle's instrument panel or under cover, so he has to bend down to check the foot pedal every time he performs a tilt operation. However, there was a problem in that the tilt operation was troublesome.

Therefore, in view of this, the present invention focuses on the use of a footrest that has been commonly used and is placed in a position that is easily visible to the driver, and combines the function of a footrest with a tilt operation function. It is an object of the present invention to provide a tilting operation device for a tilt handle that improves tilting operability and prevents erroneous operation by using a tilting operation pedal that also serves as a footrest.

That is, the present invention provides a tilt steering wheel tilt operating device that is provided with a locking device that locks and unlocks the tilting of a steering wheel or a steering shaft to which the steering wheel is attached, which is pivotably pivoted to a vehicle body,
A tilt operation pedal that also functions as a footrest and is linked to the locking device, and a lock that is pivotally attached to the vehicle body and engages with the pedal to prevent the pedal from tilting when the tilt operation pedal is used as a footrest. The invention is characterized in that it includes a member.

Furthermore, in addition to the above-mentioned tilt operation pedal and locking member, the present invention provides a device that is fixed to the tilt operation pedal, and that clamps the locking member when the locking device is unlocked, and that locks the locking member when the locking device is locked. By providing a clamping member that releases the grip on the member, the clamping member automates the engagement operation of the locking member with respect to the tilt operation pedal, so that the tilt operation pedal can be quickly switched. It is.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

This unlocks the tilting of the

Note that I is a steering column and 8 is a soundproof cover.

At the foot position (footrest position) of the vehicle body 1, there is a bracket 9 as shown in detail in FIGS. 2 to 5.
is fixed by fastening bolts 10, 10, and a tilt operation pedal 1 which also serves as a footrest is attached to the rear of the bracket 9.
1 is pivotally attached near its lower end by a pin 12, and the upper end of the tilt operation pedal 11 is connected to the lock lever 6a of the lock device 6 via a connecting wire 13 so as to be interlocked with the lock lever 6a of the locking device 6. and tilt operation pedal 11.
The lock lever 6a of the locking device 6 is rotated against the biasing force of the spring by the forward tilting of the locking device 6.
It is provided so that it can be unlocked.

Further, a locking member 14 is pivotably attached to the front end of the bracket 9 by a pin 15 at its front end, while the tilt operation pedal 11 is mounted opposite to the locking member 14. On the back side, there is a pivot point (pin 15) of the locking member 14.
) The locking member 1 is inserted into the notch groove 16 provided at approximately the same height position as the
A locking spring 17 is attached to lock the rear end of the locking member 14, and when the tilt operation pedal 11 is used as a footrest, the rear end of the locking member 14 is inserted into the notch groove 16 with the locking spring 17. 17 to prevent the tilt operation pedal 11 from tilting forward, and when the tilt operation pedal 11 is tilted backward from the locking position, the locking member 14 is locked with the locking spring 17. Let's break up the relationship,
The locking member 14 is configured to be rotated downward by its own weight and held on a stopper 18 provided on the bracket 9 so as not to interfere with the forward tilting operation of the tilt operation pedal 11.

Further, at the upper end of the back surface of the tilt operation pedal 11, there is a pair of clamping claws 1 that clamp the locking member 14 at the tip end.
A U-shaped clamping member 19 having 9a and 19a is attached to the screw 2.
When the locking device 6 is unlocked, the holding member 19 is fixed by a zero stop, and when the locking device 6 is unlocked, the holding member 19 is held in place by the tilt operation pedal 1.
The stopper 18 rotates forward in accordance with the forward tilting of the stopper 18.
The upper locking member 14 is held between the gripping claws 19a, 19a, and when the locking device 6 is operated to lock, the locking member 14 is held by the rearward tilting of the tilt operation pedal 11.
When the lock is completed, the locking member 14 engages with the locking spring 17, and the locking member 14
It is designed to release the grip of the

Next, the operation of the above embodiment will be explained. When the tilt operation pedal 11 is used as a footrest, the locking spring 17 engages the notch groove 16 of the tilt operation pedal 11 as shown in FIG. Since the locking member 14 is locked and the forward tilting of the tilt operation pedal 11 is prevented, the pressing force of the driver's foot is applied to the upper side of the swing center (pin 12) of the tilt operation pedal 11. Even if the force is applied to the pedal, the tilt operation pedal 11 does not tilt forward and stops receiving the above-mentioned pressing force, and functions as a footrest.

On the other hand, when tilting the bundle 5, step on the lower end of the tilt operation pedal 11 with the footrest in use and tilt the pedal 11 backwards, and as shown in FIG. When the locking member 14 is disengaged, the locking member 14 rotates downward due to its own weight and is stopped on the stopper 18, and accordingly, the tilt operation pedal 1
1 is in a state where it can freely swing without being blocked by the locking member 14.

When the tilt operation pedal 11 is tilted forward by stepping on the upper side of its center of rotation, the lock device 6 is interlocked with the tilt operation pedal 11 via the gear 13.
The lock lever 6a rotates counterclockwise against the biasing force of the spring, thereby unlocking the locking device 6, and in this unlocked state (i.e., the state in which the tilt operation pedal 11 is tilted forward). ), the height position of the bundle 5 is adjusted.

At this time, due to the forward tilting of the tilt operation pedal 11, the clamping member 19 is in a state of clamping the locking member 14, as shown in FIGS. 4 and 5.

Next, after adjusting the height position of the bundle 5, when the foot is released from the tilt operation pedal 11, the locking device 6 dynamically locks the steering shaft 2 by the biasing force of the spring built into the locking device 6. At the same time, in conjunction with this, the tilt operation pedal 11 returns to the rear and the locking member 1 held by the holding member 19 is rotated.
4 rotates upward and is engaged with the locking spring 17 of the tilt operation pedal 11 when the locking device 6 is locked, and at the same time is released from the clamping of the clamping member 19. Return to footrest usage state.

At that time, as the tilt operation pedal 11 moves from unlocking to locking the locking device 6, the first clutch member 14 and the locking spring 17 of the tilt operation pedal 11 are automatically held together by the first grip member 19. The footrest can be brought into use by engaging with the footrest, and the function of the tilt operation pedal 11 can be quickly switched.

The locking device 6 of the above embodiment is a device for locking and unlocking the tilting of the steering shaft 2, but the locking device 6 is a device for locking and unlocking the tilting of the steering shaft 2, but it is designed to lock and unlock a bundle in which only the steering bundle tilts without the steering shaft tilting. It goes without saying that a locking device may also be used.

As described above, according to the present invention, there is provided a tilting operation device for a tilt bundle including a locking device for locking and unlocking the tilting of a steering bundle or a steering shaft to which the bundle is attached. a tilt operation pedal which is attached to the vehicle body and also serves as a footrest and which is linked to the locking device; and a tilt operation pedal which is pivotably attached to the vehicle body and engages with the reading pedal when the tilt operation pedal is used as a footrest to prevent the pedal from tilting. By providing the locking member, the tilt operation pedal is located at a position where it can be easily seen from the driver's seat, so the tilt operation can be performed easily and erroneous operation can be reliably prevented.

Moreover, since the tilt operation pedal can be used in common as a footrest, the number of parts can be reduced, and the vehicle also has the advantage of being able to effectively utilize the narrow foot space inside the vehicle.

In general, according to the present invention, in addition to the tilt operation pedal and the locking member, the locking member is fixed to the tilt operation pedal, and when the locking device is unlocked, the locking member is clamped, and when the locking device is locked, the locking member is secured. By providing a clamping member that releases the clamping member, it is possible to automatically switch from the tilt operation to the footrest usage state, and it is possible to speed up the switching operation of the tilt operation pedal. .
