Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tilt steering wheel.The tilt steering wheel is used to adjust the steering wheel up and down according to the body shape of the driver during driving, and also to move the riding ring wheel upward.

However, with conventional steering wheels, the vertical adjustment and vertical movement of the steering wheel are performed by a single mechanism, so even if the steering wheel 7J is adjusted vertically, the steering wheel cannot be moved upward once. In some cases, there were problems such as having to adjust the steering wheel up and down again when driving.

The present invention has been devised to solve the above-mentioned problems, and an object of the present invention is that even if the steering wheel is moved up or down, the steering wheel can be returned to its original state without having to adjust the steering wheel up or down again. In order to achieve the above object, the present invention provides a lower tilt bracket attached to the dash board side, a memory bracket pivotally attached to the lower tilt bracket, and a steering wheel. An upper tilt bracket that supports the wheel and is pivotally connected to the memory bracket, and a "lower adjustment" that is provided on one pair of the two pairs of brackets that are pivotally connected to each other, and that allows the steering wheel side bracket to be freely adjusted up and down. and a vertical movement mechanism provided on the other pair of the two pairs of brackets and capable of vertically moving the bracket on the steering wheel side.

A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a plan view of the tilt handle with the steering wheel omitted, FIG. 2 is a side view of the same, and FIG. 3 is a view taken in the direction of the ■ arrow in FIG.

1 is an upper tilt bracket, 2 is an upper steering column attached to the upper tilt bracket 1, 3 is a lower tilt bracket attached to the dash board side, 4
is a lower steering column attached to the lower tilt bracket 3.

The left and right side plates 5.5 of the upper tilt bracket 1 are located inside the left and right side plates 6, 6 of the lower tilt bracket 3, and the left and right side plates 7. A memory bracket 8 is provided by interposing the upper tilt bracket 1, the lower tilt bracket 3, and the left side plate 5, 6.7 and the right side plate 5, 6.7 of the memory bracket 8 by a tilt bin 9, respectively. .

An upper steering shaft 11 with a steering wheel (not shown) attached thereto is inserted into the upper steering column 2, a lower steering shaft 12 is inserted into the lower steering column 4, and both shafts 11.12 are inserted into the upper steering column 2.
are connected via a joint 13 within the bracket 1°3.8. Note that the center of the joint 13 and the center of the tilt pin 9 are made to coincide.

A distance collar 21 of a required length is installed horizontally between the upper steering column 2 and the left and right side plates 5° 5 of the upper tilt bracket 1, and the bolts 22 are inserted through the distance collar 21 and the left and right side plates 5, 5. establish.

The left and right side plates 7, 7 of the memory bracket 8 are respectively formed with arc-shaped long grooves 23 centered on the tilt pin 9 in correspondence with the bolts 22, and the right side plate 1 is formed with an arc-shaped long groove 24.
The bolt 22 is inserted into the left and right long grooves 23, and the bolt head 22a is inserted into the locking member 2.
5 in a non-rotatable manner, and the tip threaded portion 22b is made to protrude outward from the left side plate 7.

An adjusting arm 26 is provided on the threaded portion 22b by screwing a nut portion 26a into the threaded portion 22b.

The adjustment arm 26 extends to the upper steering column 2 side, and the distance collar 21 and the bolt 2
2. A vertical adjustment mechanism 27 that allows the steering wheel to be adjusted up and down using the long groove 2324, adjustment arm 26, etc.
Configure.

When the adjustment arm 26 is swung downward, the vertical adjustment mechanism 2T applies the pinching pressure between the left side plates 5, 7 and the right side plates 5, 7 via the distance stamp collar 21, bolt 22, and adjustment arm 26. Release it and insert the bolt 22 into the long groove 23,
Upper 5 slides within 23 and uses tilt pin 9 as a fulcrum.
- When the bolt bracket 1 is configured to freely swing up and down and the adjustment arm 26 is moved upward, the left side plate 5
, 7 and the right side plates 5, 7, respectively, to fix the upper tilt bracket 1 to the memory bracket 8.

A tilt lever 31 is provided on the right side plate 7 of the memory bracket 8 and extends toward the upper steering column 2 and is swingable in the left-right direction, and a locate pin 32 is attached to the tip of the tilt lever 31.

The locating pin 32 is inserted through a fitting hole 33 formed in the left side plate 6 of the lower tilt bracket 3 and a fitting hole 34 formed in the left and right side plates 7.7 of the memory bracket 8, respectively. 32a
is urged to protrude from the fitting hole 33 of the left side plate 6 of the lower tilt bracket 3.

A tilt spring 36 is stretched between the lower tilt bracket 3 and the memory bracket 8, and urges the memory bracket 8 to move upward using the tilt pin 9 as a fulcrum.

The tilt lever 31, location 1/pin 32, fitting hole 3
3, 34, etc. constitute a vertical movement mechanism 37 that can freely move the steering wheel up and down, and when the tilt lever 31 is swung inward, the locate pin tip 32a is inserted through the fitting hole 33 of the left side plate 6. It is pulled out to release the locked state between the lower tilt bracket 3 and the memory bracket 8, and the memory bracket 8 can freely swing up and down using the tilt pin 9 as a fulcrum.

Since the present invention is configured as described above, when adjusting the steering wheel up and down, the locate pin tip 32
a into the fitting hole 33 to fix the lower tilt bracket 3 and the memory bracket 8, and then swing the adjustment lever 26 downward to connect the upper tilt bracket 1 and the memory bracket 2 with the distance bracket 21 and the bolt 22. Release the tightening of butt 8.

By releasing the tightening of both plackets 1°8 by the adjustment lever 26, the steering wheel can freely swing up and down using the tilt pin 9 as a fulcrum.The driver can now move the steering wheel up and down and make adjustments at the desired location. Swing the lever 26 upward to tighten both brackets 1 and 8, and complete the vertical adjustment of the steering wheel.

Next, when moving the steering wheel upward when getting on or off the vehicle, the tilt lever 31 is operated to swing inward.

As the tilt lever 31 swings inward, the locating pin tip 32a is pulled out from the fitting hole 33, and the locked state of the lower tilt bracket 3 and memory bracket 8 is released.
Due to the elastic force of the tilt spring 36, the steering wheel moves upward using the tilt pin 9 as a fulcrum together with the tilt bracket 1 and the memory bracket 8. Next, when the steering wheel is returned to its original state, The steering wheel is swung downward against the elastic force of the tilt spring 36. ) The tilt bracket will shift when the steering wheel swings downward.
1 and the memory bracket 8 swing together, and the fitting hole 34 of the memory bracket 8 and the lower tilt bracket 3
When the coil spring 350 is aligned with the fitting hole 33 of
Due to the elastic force, the locating pin tip 32a fits into the fitting hole 33, and the lower tilt bracket 3 and memory bracket 8
is engaged and locked, and the steering wheel returns to its original vertical adjustment state.

As is clear from the above description, according to the present invention, it is possible to easily adjust and move the steering wheel up and down, and even when the steering wheel is moved up and down, the initial vertical adjustment state is maintained. It exhibits a number of excellent effects, such as a simple structure and easy manufacture.
