Abstract

PURPOSE:To nimbly adjust the handle position and suppress the downward tilt of a jacket, etc. by elastically fitting a slider between a movable bracket on the jacket side supporting a steering shaft and a stationary bracket on the car body side. CONSTITUTION:A tilt angle adjusting device 7 of a steering wheel 2 is fitted to a jacket 6 supporting a steering shaft 1. This device 7 is provided with a pair of long holes 9a on both side walls 15a of a stationary bracket main body 15 and also with a pair of through holes on both side walls of a movable bracket main body 16, a clamp bolt 11 is inserted through these holes, an adjusting lever 12 is screwed to its tip, and both main bodies 15, 16 are tightened or loosened by its rotating operation. A tapered groove 19 narrowed downward is formed on the inner surface of both side walls 15a, and a slider 22 with both ends coupled with it and provided with a compression coil spring 21 is elastically fitted, thus preventing the downward tilt of the jacket 6, etc.

Description

[Detailed Description of the Invention] Regarding the adjustable tilt knob for $17! F! Part 1 relates to the bevel adjustment device.

The tilt handle changes the height of the steering wheel by changing the vertical angle of the steering shaft, and the steering wheel is placed in the most tilted position to match the physique of both military and military drivers. For example, FIG. 1 shows an example of this type of handle.

That is, a steering link wheel 2 is attached to a steering shaft J (coupled with a steering shaft J), and the capacity is connected to a steering gear box 4 or a connecting shaft 5 with a gear hook via a universal joint 3. The steering shaft 1 is rotatably supported by a tilt angle adjusting device 7, and a portion near one end of the steering shaft 1 is supported by a body 8 at the bottom of the instrument panel.
The trimmer 7 has a fixed bracket 9 attached to the vehicle body 8 and a movable bracket 10 fixed to the jacket 6 and movable up and down within the fixed bracket 9 together with the jacket 6, and a bolt 11 and an adjustment lever screwed into this bolt. By loosening this tightening, the bolt 11 can be moved up and down in the elongated hole 9a of the fixed bracket 9, and at the same time, the movable bracket 10 can be moved up and down to move the jacket 6. It tilts up and down.

However, with this conventional inspection device, when the adjustment lever is loosened to adjust the bevel angle, the force to support the steering wheel shaft and jacket is lost, so the jacket, etc. tilts downward by Vc. shuffle. Therefore, the only way to drive is to firmly grasp the steering wheel, apply upward force to it, adjust it to the desired angle of inclination, and then tighten the adjustment lever to fix it in that position. In general, since jackets and the like have a high kilometer, there is a problem in that an extremely large amount of force is required to operate them.

The present invention has been made as described above, and its purpose is to provide a fixed bracket attached to the KJ on the vehicle body side, a movable bracket provided on the jacket side so as to be movable within the fixed bracket, and an inner surface of the fixed bracket. a groove formed so that the interval becomes narrower toward the bottom; a sliding body supported by a movable bracket so as to be able to slide up and down within the groove; and a spring that brings the sliding body into elastic contact with the premises; By biasing the movable bracket upward with this spring, the jacket a will not tilt downward even if the fixed bracket and movable bracket are loosened in the adjustment device, and therefore the jacket a will not be tilted downward. To provide a tilt handle with a tilt handle that can be easily and easily installed at a desired angle of inclination, and can be miniaturized by fitting a spring within a bracket.

This research will be explained below with reference to examples shown in FIGS. 2 and 43.

To describe the configuration of Part 5, the present invention uses a spring indirectly to bias a jacket, etc. upward, and in the figure, 1 is a steering shaft, 6 is a jacket, and 7 is a fixed bracket. 9 and ringing bracket h 1
This is an inclination angle adjusting device that adjusts the angle between 0 and 1.

The fixing bracket 9 of this adjustment device 7 consists of a plate-shaped fixture 4 which is bolted to the vehicle body 8, and a U-shaped bracket main body 15 which is fixed by welding or the like to a substantially central part of this fixture. The bracket main body 15 has a pair of vertical elongated holes 9a, 9a in both side walls 15a, 15a. The movable bracket [0 has a bracket body 16 fixed to the jacket 6 with a shape inserted between the front g-piped side walls 15a, 15a, and a reinforcing portion ladle 17 is attached as necessary. Bracket body 16 has inner wall L6a, 16aK through hole 1
0a, LOa respectively,
(l a , L (l a ) The tightening bolt 11 is inserted from one side through the l a .
An adjustment lever 120 having a head 12b having a head 12a is screwed together, and the fixed bracket 9 and the movable bracket 0 are tightened or loosened by rotating the lever 17 and the head 12b. lla is a parallel plane portion that engages with the elongated hole 9a, and 18 is a washer.

In addition, both side walls 15 of the bracket main body of the fixed bracket 9
a, 15a, there are a pair of tapered grooves 19, . 19 is recessed.

Then, a horizontal through hole 20 is opened across the bracket body side walls 16a, +6& and the reinforcing member 17 of the movable bracket 10 so as to correspond to the grooves 19, 19, and a pair of holes are formed with the compression coil spring 21 in the center. Cannonball-shaped sliding body 22
, 22 is loaded. The sliding bodies 22, 22 have their pointed ends in elastic contact with the inner surfaces of the grooves 19, 19.

Next, the operation will be described. When the adjustment lever t2 is rotated in one direction, the lever 12 screws along the bolt 11 and fixes the movable bracket 10 on both sides of the fixed bracket 9 (Mu&J5a, i5a). , this jacket 6
Fix etc. On the other hand, when the adjustment lever 12 is rotated in the other direction, the tightening force is reduced and the movable bracket 10 is no longer restrained by the fixed bracket 9. At this time, the jacket 6 etc. tries to move downward due to its own weight, but the downward movement is suppressed or prevented by the elastic frictional force between the sliding bodies 22 and the grooves 1 and 19 and the lever surfaces. Ru. And, the jacket a has a force of 21, and the jacket has a sliding body of 2.
2. Stop at the tilt angle position where the frictional forces, etc. at 2 and 22 are balanced.

As described above, according to the present invention, the jacket can be tilted toward the earthwork by applying an extremely small force to the jacket, and the height position of the steering wheel can be easily adjusted to A. The shape of the cut grooves 19 allows the jacket to be balanced and held at any desired position. Historically, the spring can be mounted within the bracket, making it more compact.
