Description

[Detailed explanation of the idea] The present invention relates to a moderation device for a direction indicator.

Conventionally, when a moderation device for a direction indicator is operated to a predetermined direction indicating position to the left or right of a neutral position, the control lever is engaged and restrained at that position and held at that position with a predetermined holding force. A first moderating device is provided which is formed by cooperation of a movable member and a support member which hold and protrude the movable member.

Furthermore, a second moderation device is also provided, which acts as a collision feel section just before the engagement and restraint is reached at the predetermined direction indication position, and by holding the operating lever at the collision sensation section position, direction indication is provided. An electrical circuit is formed that flashes the lights, providing a signal for the vehicle to change lanes.

Furthermore, when the operating lever is released, the first moderation device automatically returns to the original neutral position due to the return force of the first moderation device.

What is important about the above-mentioned moderation device is that within a relatively small predetermined stroke from the neutral position to the predetermined direction indicating position, the second moderation device for lane change operation and the direction indicating position. The feel of the first moderation device at each point is clear and favorable, and there is no incomplete contact, etc., especially at the impact feel part position where lane changes are made, and the electric circuit is reliably connected. must be formed.

However, in these conventional moderation devices, for example, a protrusion or depression is provided immediately before the apex of the slope portion of the moderation mountain formed on the moderation member of the first moderation device, and an elastic contact member that comes into elastic contact with the protrusion or depression. In the structure in which the impact feeling is obtained by the movable member, the impact feeling cannot be freely selected in relation to the swing stroke of the movable member, and it is unclear, or there are other known embodiments. In the Japanese Utility Model Publication No. 51-11330, etc., there were many problems such as the number of parts was large, the structure was complicated, and manufacturing costs could not be reduced.

The present invention was devised in view of the problem of tilting, that is, the 10th elastic contact member is elastically loaded with the first moderation device that senses the engagement restraint by operating the lever to the left and right direction indicating positions. A second elastic contact member is provided on the rear surface of the guide member integrally with the guide member, and a barrier is provided at the tip of the movable member integrally with the movable member, and the protrusion on the inner surface of the barrier is provided with the second elastic contact member integrally with the guide member. To provide a moderation device for a direction indicator, which has a simple component structure in which a second elastic contact member makes contact with the tenth elastic contact member and obtains a feeling of impact through a separate route, and has a smaller number of parts. It is.

A second impact part 5d is provided protrudingly, and a moderation -5e is provided on the outside.
is in great shape.

A guide member 8 in which a steel ball 7 is resiliently loaded as a tenth elastic contact member via a spring 6 is fixed by a tightening tool 9 to a portion of the support member 10 forming the main body facing the moderating ridge 5e of the ratchet 50. The steel ball 7 press-fits into the moderation -5e and presses the ratchet 5 inwardly into the movable member 2 so that the bottom surface 2cs of the first fitting groove 2a of the movable member 2 and the second The first protruding piece 5a and the second protruding piece 5b of the ratchet 5 corresponding to the bottom surface 2d of the fitting groove 2b are brought into pressure contact with each other.

Therefore, the 2-chip soto 50 moderation mountain 5es spring 6 and the steel ball 7 constitute a first moderation mechanism for engaging and restraining the movable member 2 in the neutral position, the leftward pointing position, and the rightward pointing position. are doing.

Furthermore, a hemispherical protrusion 8b is formed at the center of the rear surface 8a of the guide member 8 in which the spring 6 and the steel ball 7 as the first elastic contact member are elastically loaded, and a cut groove is formed at the center of the rear surface 8a of the guide member 8. 8c and 8d form a band-shaped elastic piece 8e as a second elastic contact member, and the protrusion 8 of the band-shaped elastic piece 8e
b is pressed against the inner surface 2f of the partition wall 2e of the movable member 2 in cooperation with the spring pressure of the spring 6 inserted into the inner surface.

In addition, a protruding surface portion 2g is provided on the inner surface 2f of the partition wall 2e of the movable member 2.
, 2h are formed, and immediately before the movable member 2 is engaged and restrained at the direction indicating position by operation in the leftward or rightward direction, that is, the vertex 5f of the moderation -5e of the 2-chatch 5,
Or the hemispherical protrusion 8b of the elastic piece 8e on the rear surface 8a of the guide member 8 just before the steel ball 7 overcomes 5g.
The second moderation device is configured such that the second moderation device hits the protruding surface portion 2g% or 2h and provides a feeling of impact.

Further, 10 is a cancel cam, and a protrusion 1 of the cam
0a is the first abutting portion 5cs or the second abutting portion 5 of the ratchet 5 when the operating lever is operated to the direction indicating position.
In order to automatically return the movable member 2 to the neutral position when the movable member 2 collides with It is something that

Next, the operation of the moderation device for a direction indicator according to the present invention having the above configuration will be explained.

When the operating lever 4 is operated to the left or right direction indicating position, the movable member 2 and the ratchet 5 attached to the movable member are moved to the guide member 8 fixed to the support member 1 forming the main body. The movable member 2 resists the force of being pressed by the steel ball 7, which is the first elastic contact member.
By swinging around the shaft 2k of the ratchet 5, the second point of the rear surface 8a of the guide member 8 immediately before the vertex 5f of the moderation -5e or 5g of the ratchet 5 gets over the steel ball 7.
The protrusion 2g or 2h of the barrier wall 2e of the movable member 2 collides with the hemispherical protrusion 8b of the elastic piece 8e, which is the elastic contact member, and the impact feeling can be sensed here. By holding the operating lever 4 in this position, the direction indicator switch 3 becomes QN and the desired direction indicator light can be made to blink. In other words, the direction indicator light is turned on only while the operating lever 4 is held by hand. When the user releases the operating lever 4 at this position, the movable member 2 is returned to its original position by the pressing force of the steel ball 7 via the ratchet 5.

(This is used when driving to change lanes, etc., with a small steering wheel rotation operation, and acts as a second moderation device to prevent the driver from forgetting to turn on the turn signal while it is still flashing.)

Furthermore, when an operating force is further applied to the operating lever 4 against the impact force at the impact feel position, the protrusion 8b of the guide member 8 is moved against the protrusion 2gs of the partition wall 2e of the movable member 2. Or, the steel ball 7 loaded in the guide member 8 moves over the protrusion 2h and the moderation of the ratchet 5 is -5e.
Vertex 5f.

Otherwise, the movable member 2 is engaged and restrained at a predetermined direction indicating position via the ratchet 5, and the desired direction indicator light continues from the above-mentioned impact feeling. , the direction indicator switch 3 blinks.

In this way, it functions as a first moderation device that performs the normal flashing operation of the direction indicator.

Incidentally, when the vehicle completes the predetermined direction change and the steering wheel is rotated in the opposite direction to restore it to its original position, the protrusion 10a of the cancel cam 10
The movable member 2 is automatically returned to its original neutral position by contacting the first abutting portion 5cs or the second abutting portion 5d of the ratchet 5 located within the rotation locus a.

Of course, it goes without saying that it is also possible to manually return the vehicle to the original neutral position from the direction indicating position.

The moderation device for a direction indicator according to the present invention having the above-described configuration and operation has the following effects.

(a) A second moderation device on the outer periphery of the first moderation device for engaging and restraining the left or right direction indicating position, which uses a separate route to sense the switch ON position for lane change operation by feeling the impact. Since the device is installed, it is possible to freely select the height, height, and position of the impact sensation in a desired and preferable state, and a large movement stroke due to rocking can be achieved, so that the impact positioning associated with turning on the switch is ensured. Adverse effects on contact portions are also eliminated.

(0) Since the second moderation device for lane change operation is integrally formed with the movable member and the guide member, there is no special part for the second moderation device, resulting in an extremely simple configuration. In addition, the assembly man-hours for this purpose remain unchanged and can be easily done.
A moderation device with low manufacturing cost can be provided.
