Description

[Detailed Description of the Invention] This invention relates to an improvement of a tilt handle attachment device.

Conventionally, as a mounting device for a tilt steering wheel, for example, the devices shown in FIGS.
As shown in the mounting device shown in the figure, the column bracket 3 of the steering column 2, which holds the steering shaft 1 at its axis, is held between the inverted U-shaped fixing brackets 4, and the column bracket 3 and the fixing bracket 4 are penetrated. Loosen the vertically movable tightening bolt 5 with the tilt lever 6,
There is one in which the steering column 2 is swung in the vertical direction of the vehicle body 8 along the guide hole 7 of the fixed bracket 4, so that the mounting angle can be adjusted.

However, in the above-mentioned tilt handle mounting device, it is necessary to separately provide a mounting plate 9 on the top of the fixing bracket 4 for mounting on the vehicle body 8, and to fix it by welding.
Both side walls 4a, 4a of the fixed bracket 4 are provided with tightening bolts 5.
Since it is necessary to deform in the width direction when tightening, there is a drawback that the rigidity in the width direction inevitably decreases.

This invention was made in view of the above-mentioned conventional problems, and the fixing bracket is connected between a pair of side walls, a vehicle body mounting part bent outward from the upper part of the side walls, and a lower part of the side walls. It is integrally formed into a roughly U-shape with the connecting bottom part that connects the bracket, eliminating the need for a conventional mounting plate, and the side wall part on one side of the fixing bracket and the vehicle body mounting part are integrally connected at the reinforced corner part. , a deformable part that can be deformed in the width direction is formed in the side wall part of the external force by cutting out a part of the connecting bottom part to improve the rigidity in the width direction, and a through guide hole is provided near the deformed part to improve the width. This is to ensure directional deformation.

Hereinafter, embodiments of this invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 3, 4, and 5, the steering shaft 11 held at the axial center of the steering column 10 has its lower end connected to a steering gear box (not shown) via a universal coupling.

), the handle 12 is fixed to the upper end thereof, and the handle 12 is connected to the universal coupling by a steering shaft 11 that can swing vertically about the center f.
The height can be adjusted.

The upper surface of a column bracket 13 having a roughly mountain-shaped shape having a pair of vertical side walls 13a and 13b is integrally fixed to the lower surface of the steering column 10 by welding or the like.

On the other hand, the fixed bracket 14 is
A pair of wide side walls 15a, 15b circumscribing both side walls 13a, 13b of No. 3, vehicle body mounting portions 16a, 16b bent outward from the tops of the side walls 15a, 15b, and the side wall 15- A and a narrow connecting bottom 17 connecting the lower portions of 15b form a roughly U-shaped integral structure.

Both side wall portions 13a of the column bracket 13.

A series of tightening bolts 19 are provided that pass through bolt holes 13c and 13d drilled in bolt holes 13b and guide holes 18a and 18b drilled in both side walls 15a and 15b of the fixing bracket 14. A nut 22, to which the tilt lever 20 is attached with a bolt 21, is screwed into the threaded portion of the tilt lever 20.

A pin 23 is fixed between both side walls 15a and 15b of the fixing bracket 14 on the side of the tightening bolt 19, and
One end of the wire spring 24 wound around the column bracket 13 is hooked onto the connecting bottom 17, and the other end is attached to the column bracket 13.
Both side wall portions 13a.

The tightening bolt 19 is hooked onto the bush 25 passing through between 13b and the wire spring 24 constantly urges the steering column 10 toward the upper blade.

Further, as shown in FIG. 7, the side wall portion 15a on one side of the fixing bracket 14 and the vehicle body attachment portion 16a are integrally connected at a substantially triangular auxiliary corner portion 26, and as shown in FIG. By cutting out a portion of the connecting bottom portion 17, the other side wall portion 1sbg is defined by a dashed line connecting the end of the vehicle body mounting portion 16b and the end of the connecting bottom portion 17.
This is a triangular deformable portion 27 that is deformable in the width direction without a rib portion (indicated by crosshatching in the figure).

) is formed.

Note that both side wall portions 15a of the fixing bracket 14.

Guide holes 18a and 18b are provided in the deformed portion 27.

The fixing bracket 14 has a vehicle body mounting portion 16a.

From the bolt holes 16c and 16dl of 16b, bolts 29 and 29 are attached to the vehicle body (lower part of the instrument panel) 28.
Fasten and secure.

If you configure the tilt handle mounting device as described above,
When the tilt lever 20 is manually operated to weaken the tightening force of the tightening bolt 19, the steering column 10 is biased upward by σ by the wire spring 24, and the steering column 1
0 can be easily adjusted up and down.

When the driver adjusts the angle by holding the handle 12 and then operates the tilt lever 20 to increase the tightening force of the tightening bolt 19, the side wall portion 15 on one side of the fixing bracket 14
Since the portion a is reinforced by the reinforcing corner portion 26, the deformed portion 27 of the other side wall portion 15b bends in the width direction, and the both side wall portions 15a.

Tighten the column bracket 13 between 15b and 15b.

Thereby, the steering column 10 is fixed at the position adjusted by the driver.

As is clear from the above explanation (this invention has a fixing bracket integrally constructed with a pair of side walls, a vehicle body mounting part, and a connecting bottom part), it is not necessary to provide a separate mounting plate as in the conventional case. Since there are no welded parts, it can be manufactured at low cost, lightweight, and compact, and has high reliability because there are no welded parts.

Furthermore, one side wall is strongly reinforced at the reinforced corner, a deformed part is formed in the other side wall, and a guide hole is provided near the deformed part, so the rigidity in the width direction is improved. Tightening with a tightening bolt can sometimes reliably tighten and fix the steering column by deforming the deformed part.
