Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized by the forward rotation of a reversible rotating body that rotates in the forward and reverse directions in conjunction with the reciprocating swing of the operating lever each time the operating lever is operated by manual and automatic return.
The closing of the contacts of the passing switch directly connected to the power supply is controlled during the daytime, and the opening of the contacts is controlled by the subsequent rotation in the opposite direction, and the one-way clutch mechanism is used to control the forward or reverse rotation of the reversible rotating body. The interlocking rotation of the one-way rotating body that is interlocked with the rotation in the direction of the daimer controls the alternate opening and closing of the main width headlight circuit contacts of the daimer switch connected to the power source via the night light switch.・Related to the passing switch, the swinging motion of the operating lever that can be returned automatically is converted into the rotational motion of a forward/reverse rotating body and a unidirectional rotating body to suit the respective performance of the passing switch and daymer switch. The purpose is to cause the switch operation to occur in a related manner.

An embodiment of the invention will be described with reference to the accompanying drawings.

In Figures 1 and 2, reference numeral 1 denotes a direction indicator for an automobile, which includes a main body 2 provided with a cylindrical portion 3 into which a steering shaft is loosely inserted, and a shaft fitting hole provided at one outer end of the body 2. It consists of a movable bracket 5 that rotates on the main body 2 by fitting an axle 6 into the movable bracket 5, and fitting an operating lever 8 into a lever fitting groove 7 provided in the bracket to align the center line of the axle fitting hole 4 and the axle 6. It is fitted so that it can swing up and down by the horizontal shaft 9 directly above it. Reference numeral 10 denotes a moderation mechanism for holding the movable bracket 5 that pivots between a neutral position and a left/right direction indicating position, and is provided on the main body 2 and the movable bracket 5 in a known manner. 11 is a direction indicating switch.

A core rod 13, which rotates to four positions as shown in FIG. 4, is inserted into the operating lever 8 by means of a knob 14, and a rotating piece 15 is fixed to its protruding front end. The rotating piece 15 is formed with a lower protruding leg 16 having an engaging element 17 facing directly below the center line of the shaft fitting hole 4 and the shaft element 6, and a protruding ball 12 provided on the front end surface of the operating lever 8. Moderation valley 1 that engages each of the four positions mentioned above.
8 will be provided. A floating spring 19 supported by the main body 2 is applied to the lower surface of the front end of the core rod 13, so that the operating lever 8 is brought into contact with the edge of the main body 2 as shown in FIG. 14 is pulled up to cause it to swing at a certain angle.

The main body 2 is provided with a switch box 20 corresponding to the operating lever 8 and the lower surface of the front end of the core rod 13, and a light switch 21 having a movable part 22 in which the above-mentioned engager 17 is sandwiched between opposing walls 23 is attached. In addition, a daimer/passing switch 24 is provided. The light switch 21 is connected to the core rod 1 by the knob 14.
3, the movable part 22 is moved by the engaging element 17 of the rotating piece 15 to any of the headlamp circuit closing position, the small light circuit closing position, the OFF position, and the parking light circuit closing position.

The switch box 20 is provided with a horizontal axis 25 in the front and back direction supported by the main body 2.
A reversible rotary body 26 provided with a pinion 27 and a one-way rotary body 28 are joined and fitted to freely rotate, and the sector gear 2 meshes with the pinion 27.
The handle 30 of the handle 30 is pivotally supported by a shaft 31, a pull-up spring 32 is applied to the rear end of the handle 30, and the lower end protrusion of the vertically movable piece 34 fitted into the slit 33 is connected to the shaft 31 of the handle 30. The upper end of the vertically movable piece 34 contacts the lower surface of the front end of the core rod 13. (5th and 6th
In the above structure, when the operating lever 8 is in the state shown by the solid line in FIG. 1, the sector gear 29 is at the angle shown by the solid line in FIG. With the constant rocking movement of the front end of the operating lever 8, the fan-shaped gear 29 is pushed by the vertical moving piece 34 to the angle shown by the chain line, rotating the pinion 27 and the reversible rotating body 26 by 180 degrees in the forward rotation direction, and operation is performed. At the same time as removing the swing operation force of the lever 8, the sector gear 29
causes the pinion 27 and the reversible rotor 26 to return to the solid line position by the elasticity of the floating spring 19 while causing the pinion 27 and the reversible rotor 26 to return in the reverse direction.

Between the reversible rotator 26 and the one-way rotator 28, when the reversible rotor 26 rotates 180 degrees in the forward direction as described above, the one-way rotor 28 is interlocked, and the reversible rotator 26 rotates in the reverse direction. One-way rotating body 2 when rotating
One-way clutch mechanism 3 for keeping 8 stationary
5 will be provided. As an example, an engagement hole 36 having a sliding slope 37 in the reverse direction is provided on the end face of the reversible rotary body 26, and an ejecting ball 38 on which a spring force is applied is provided on the end face of the one-way rotary body 28 for engagement. Matching hole 36
to be inserted into. The one-way clutch mechanism 35 may interlock the one-way rotor 28 when the reversible rotor 26 rotates in reverse.

The reversible rotator 26 is provided with a protrusion 41 that protrudes upward when the operating lever 8 is at the angle shown by the solid line in FIG. 43 will be provided. Further, an elastic contact piece 47 is provided at the lower part of the reversible rotary body 26 to separate from the fixed contact 46 when the protruding piece 41 is in the upper position, thereby forming a passing switch 45 directly connected to the power source. Above and below the protrusion 43 of the one-way rotating body 28, a light switch 2 is installed.
A fixed terminal 49 that is connected to the power supply when the headlight circuit 1 is in the closed position, a first elastic contact piece 50 that comes into elastic contact with the upper and lower parts of the narrow diameter portion 42, and a second elastic contact piece of the sub-headlamp circuit. Daymer switch 48 consisting of 51
Set up. The first and second elastic contact pieces 50 and 51 include an engagement hole 52 into which the tip of the protrusion 43 is fitted;
54, and guide pieces 53 and 55 for assisting the protrusion 43 to escape in the normal rotational direction. 1st
The second elastic contact pieces 50, 51 are in contact with the outer periphery of the narrow diameter portion 42 and the fixed contact 49, but the protrusion 43 is inserted into one of the engagement holes 52, 54 as shown in FIG. When this happens, one of the elastic contact pieces provided with the engagement hole separates from the fixed contact 49.

To explain the operation of this embodiment, the light switch 21 is operated by the knob 14 during the daytime when the movable part 22 of the light switch 21 is set to a position other than the headlamp circuit closed position by the engager 17 provided on the rotary piece 15 of the core rod 13. When the lever 8 is swung against the floating spring 19, the sector gear 29 is moved to the angle shown by the two-dot chain line in FIG. When it is rotated 180 degrees forward and the protruding piece 41 causes the elastic contact piece 47 of the pushing switch 45 to come into contact with the fixed contact 46, the operating lever 8 is released and the floating spring 19 automatically moves back. The vertically movable piece 34 and the sector gear 29 move back and rotate the reversible rotating body 26 in the opposite direction. Therefore, the passing switch 45 is turned off. Therefore, this repetition causes the main headlights to flash and generates a daytime passing signal.

The one-way rotating body 28 rotates the protrusion 43 of the narrow diameter portion 42,
First and second elastic contact pieces 5 of daymer switch 48
However, when the reversible rotor 26 rotates in the forward direction, it is rotated clockwise via the one-way clutch mechanism 35, and is stopped. It rotates until the part 43 fits into the engagement hole of another elastic contact piece, and stops when the reversible rotor 26 rotates in the opposite direction. For this reason, the operating lever 8
For each reciprocating swinging hand, the protrusion 43 is alternately moved to the first and second positions.
It contacts the elastic contact pieces 50, 51, thereby producing a daimer switch action that alternately contacts the fixed contact 49, and at night when the movable part 22 of the light switch 21 is in the headlamp circuit closed position, the main front Switches on the headlights and sub-headlights alternately. Furthermore, by frequently swinging the operating lever 8, the lighting of the main headlights is frequently switched to generate a passing signal at night. Of course, even at night, the passing switch 45 is operated by the reversible rotator 26 in the same way as during the day, but since the movement of the first elastic contact piece 50 toward and away from the fixed contact 49 is almost synchronized, the operation of the passing switch 45 is It's not a hindrance at all.

As described in detail above, the present invention controls the opening and closing of a passing switch by a reversible rotary body that rotates forward and backward in conjunction with one reciprocating swing of an operating lever having an automatic return function. Does it have a structure in which switching of the main and sub-headlamp circuits of the daymer switch is sequentially controlled for each reciprocating movement of the swing lever by a one-way rotating body that rotates intermittently in one direction via a clutch? Therefore, the operations of the passing switch and the dimmer switch can be controlled in close relation to meet the performance.
