Description

[Detailed Description of the Invention] The present invention relates to a direction indicator that is attached to a steering shaft of an automobile.

Conventional direction indicators are shown in Figures 1 and 2.
It was configured as shown in the figure.

That is, a movable bracket 4 is rotatably arranged on the upper surface of the floor plate 3 of the cylindrical case portion 2 of the main body 1, a cylindrical portion 5 through which the steering shaft passes is provided at the center of the movable bracket 4, and a shaft is mounted on one side of the cylindrical portion 5. A hole 6 is provided, and an engagement wall 7 for turn moderation facing the cylinder portion 5 in a V shape is provided on the other side, and an opening 8 is provided in the floor plate 3 inside this engagement wall 7. An operating lever 10 is attached to one end of the movable bracket 4 in which the shaft portion 9 is fitted into the shaft hole 6.
A protruding piece 11 is provided at the other end of the movable bracket 4 facing close to the engaging wall 7, a hole 12 is provided in the protruding piece 11, and a spring 13 and a ball 14 are housed in the hole 12. And this ball 14
is brought into pressure contact with the engagement wall 7, and an engagement piece 15 is provided on the bottom surface of the tip of the protruding piece 11 to pass through the opening 8 and engage with the lower end surface of the opening 8.

When a downward movement force is applied to the operating lever 10, this engaging piece 15 causes the protruding piece 11 side of the movable bracket 4 to rise, causing the ball 14 to protrude from the hole 12, or preventing the rotational movement of the movable bracket 4. It worked to prevent this from occurring.

However, there is a considerable distance between the engagement piece 15 and the part that engages with the lower end surface of the opening 8, and since the engagement piece 15 itself has elasticity, it can move considerably when a large force is applied to the operating lever 10 to move it downward. There was a problem in that the protruding piece 11 side of the bracket 4 lifted up, the moderation ball 14 jumped out of the hole 12, and the movement of the movable bracket 4 became uncontrolled.

The present invention eliminates the above-mentioned conventional drawbacks, and aims to provide a direction indicator in which the movable bracket does not lift up even when a large downward force is applied to the operating lever, and the moderation ball does not pop out. This is the purpose.

In order to achieve the above object, the present invention provides a horizontal engagement protrusion on the engagement wall for turn moderation to provide moderation to the movable bracket, and this engagement protrusion is placed in the cut groove of the protrusion of the movable bracket. The movable bracket is characterized in that it is recessed into engagement so that the movable bracket can be reliably prevented from lifting no matter how large a downward force is applied to the operating lever.

Embodiments of the present invention will be described below with reference to FIGS. 3 to 7 of the drawings.

16 is a cylindrical portion 1 through which the steering shaft is inserted.
7, and has various switches built into it, such as a direction indicator switch, a hazard switch, a daylight switch, a window watch switch, a wiper switch, etc. On the ceiling surface of this main body 16 are A movable bracket 19 is rotatably connected to the cylindrical portion 17 via a support shaft 18 . This movable bracket 19
An operating lever 20 is coupled to a portion of the lever 20 in a horizontally fixed manner and movable up and down. A protruding part 21 is provided on the opposite side of the movable bracket 19 from the mounting part of the operating lever 20, and this protruding part 21 is provided with a 22 (used as an example of a through-hole storage part),
A coil spring 23 and a ball 24 are housed in the through hole 22, and one end of the spring 23 is locked to a canceling gratch 25 installed on the movable bracket 19.

Further, a cut groove 26 is formed at the lower part of the through hole 22 of the protrusion 21 .

On the main body 16 corresponding to the protrusion 21 of the movable bracket 19, a wave-shaped engagement wall 27 for turn moderation is provided upwardly, and the protrusion 21 of the engagement wall 27 (that is, the operation lever A horizontal engaging protrusion 28 is provided in the middle in the height direction on the 20th direction) side.

The above-mentioned ball 24 is pressed against the wave-shaped cam surface 29 of the engagement wall 27 by the elastic force of the coil spring 23, and the engagement protrusion 28 is fitted into the cut groove 26.

Further, a lever 30 for controlling a window watch switch and a wiper switch is attached to the main body 16. Further, a canceling cam 31 having a protrusion around the periphery is rotatably mounted on the cylindrical portion 17 of the main body 16.

With this configuration, when the operating lever 20 is rotated to either the left or right, the movable bracket 19 moves to the support shaft 1.
Rotates around 8. This rotation causes the ball 24
is the engagement wall 2 while compressing the coil spring 23.
The movable bracket 19 slides on the back-shaped cam surface 29 of 7 to moderate the rotation of the movable bracket 19.
The direction switch is controlled by the rotation of the .

In this state, by turning the handle back, the canceling cam 31 will move the canceling ratchet 2.
5 to return the movable bracket 19 to the neutral position shown in FIG.

Next, when the control lever 20 is rotated downward to control the daymer switch and the headlight beam is switched from the low beam to the upper beam, the protrusion 21 side of the movable bracket 19 receives a force that lifts it up, but the protrusion 21 Since the engagement protrusion 28 of the engagement wall 27 is fitted into the cut groove 26 of the ball 24, it is possible to completely prevent the ball 24 from rising and jumping out from the through hole 22 of the protrusion 21. .

As the direction indicator of the present invention is constructed as described above, the engagement protrusion of the engagement wall for turning moderation of the main body is engaged with the cut groove of the protrusion of the movable bracket, so that both Since the movable bracket can be made quite rigid, it is possible to reliably prevent the movable bracket from lifting up, there is no risk of the moderation ball popping out and making the movable bracket's operation unstable, and the structure is simple. Furthermore, it has the advantage of functioning as a guide for the rotation of the movable bracket, resulting in stable and high-quality operation, and is of great practical value.

In addition, in the present invention, the engagement ridge of the engagement wall protrudes horizontally in the direction of the operating lever, so when assembling the movable bracket, first place the ball on the engagement ridge, and then place the ball on the movable bracket. If you push the protrusion of the bracket toward the protrusion, the ball will be easily stored in the storage part of the protrusion, and the groove below this storage and the engagement protrusion on the engagement wall will also easily engage, preventing any blockage. Storing the ball and engaging the engagement protrusion with the cut groove can be done in one push with a push operation, resulting in extremely high workability.
