BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a push cancel switch for winkers.

[0002]

2. Description of the Related Art A push cancel switch for a winker is known. For example, the one disclosed in Japanese Utility Model Publication No. 4-6111 has a case, a terminal connected to a turn signal circuit, and a rotatably supported inside the case. A holder provided with a movable contact for contacting and separating from the terminal, a lever for rotating the holder, a holding mechanism for holding the holder at a predetermined rotating position or a neutral position, and a lever for moving the lever to the neutral position. It includes a guide member for guiding, a cam mechanism for returning the holder from the rotating position to the neutral position when the lever is pushed in from the neutral position, and a terminal base that covers the opening of the case.

[0003]

By the way, in the case of the above structure, since only one circuit is provided and the holder is provided only on one side of the lever, the contact portion is apt to be unevenly worn. Therefore, an object of the present invention is to provide a push cancel switch that is resistant to uneven wear and has a plurality of circuits.

[0004]

In order to solve the above-mentioned problems, a push cancel switch for a winker according to the present invention is based on the above-mentioned known example, and a terminal is provided in a case and either a winker circuit or another circuit is provided. The holder includes a first terminal connected to the heel and a second terminal provided on the terminal base and connected to a circuit different from the first terminal, and the holder is located on the first terminal side with the line connecting the lever and the guide member interposed therebetween. And a second holder arranged on the second terminal side, and each of these holders is rotated by a lever or the other holder.

[0005]

The first terminal is connected to, for example, a winker circuit and the second terminal is connected to another circuit, the first holder is provided with the cam mechanism and the holding mechanism, and the second holder is provided with the cam mechanism and the first holder. When engaged so as to rotate integrally, both holders also rotate when the lever is rotated, the movable contact of the first holder contacts and separates from the first terminal, and the blinker circuit is switched, and the second holder moves. The contact contacts and separates from the second terminal to switch another circuit. When the lever is pushed in, both holders are push cancelled and return to the neutral position. At this time, since the first holder and the second holder are arranged above and below the lever with the line connecting the lever and the guide member being sandwiched therebetween, uneven wear of each contact portion is reduced.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment will be described with reference to the drawings. Figure 1
And, as shown in FIG. 2, the switch includes a case 10,

In addition, a click groove 15 (see FIG. 6) forming a holding mechanism is formed on one side of the corner portion of the case 10 near the coupler portion 13, and a corner portion on the side where the lever 40 extends to the outside is formed. Rotation stoppers 16 and 17 for the first holder 20 and the second holder 30 are formed.

A pentagonal cam hole 22 similar to a home base is formed in the center of the first holder 20, and an attachment step portion 23 of a movable contact 24 connected to the first terminal 12 is formed at one edge of the first holder 20. The engagement protrusion 23a is further formed in a protruding manner on a part of this.

A mounting step 25 and a click holder 26 are also formed on the other edge, and the engaging projection 2 is attached to the mounting step 25.
The click holder 26 accommodates a spring 27 and a ball 28 that form a holding mechanism.

The second holder 30 has substantially the same shape as the first holder 20, and is provided with a cam hole 32 at the center and a mounting step 33 and a movable contact 34 at one side edge. Further, the mounting step portion 35 and the movable contact 36 are also symmetrically provided on the other side edge portion.

The movable contacts 34 and 36 are adapted to come into contact with and separate from the second terminal 62 provided on the back side of the terminal base 60.

Protrusions 43 and 44 are formed above and below the tip of the body 41 of the lever 40 so as to project in opposite vertical directions. These enter the cam holes 22 or 32 and constitute a part of the cam mechanism, and are formed in an elongated shape along the length direction of the main body 41.

A shaft hole opened toward the tip is formed in the main body 41, and a click holder 45 is formed in this shaft hole portion, and a spring 46 and a ball 4 are provided therein.
7 are accommodated.

The guide member 50 is a mounting wall 51 fitted inside the wall portion 19 on the coupler portion 13 side of the case 10.
A guide plate 53 projecting inwardly of the case 10 substantially on the axis of the main body 41, and a partition wall 5 extending into the coupler 13.
4 and 4 are integrally formed. The guide plate 53 is provided with a substantially V-shaped guide portion 52 for guiding the ball 47 toward the neutral position.

As is apparent from FIG. 3 showing this switch from the direction of arrow A in FIG. 1, the terminal base 60 is a member for covering the opening of the case 10, and the second terminal 62 provided on the back side thereof. Part of the terminal base 6
It extends to the back side of the coupler cover 61 which is formed integrally with 0 and covers the mounting surface 14 of the coupler portion 13, and is connected to a winker circuit such as a position circuit and another circuit here.

FIG. 4 shows the first holder 20 and the second holder 3.
0 and the state of being integrated with the lever 40, B of FIG.
5 is a view from the direction of the arrow C of FIG. 4, and FIG. 6 is a view of the first holder 20 from the direction of the arrow D of FIG. 7 is an enlarged sectional view taken along line 7-7 of FIG.
Is a view showing the second holder 30 from the direction of the arrow E in FIG. 4, and FIG. 9 is an enlarged sectional view taken along line 9-9 of FIG.

As is apparent from these figures, in the first holder 20 and the second holder 30, the mounting step portions 23 and 33 are respectively by the engaging projections 23a and 33a, and the mounting step portion 25 and the mounting step 25 are respectively. The parts 35 are engaged with each other by the engagement protrusions 25a and 35a, respectively, so that the first holder 20 and the second holder 30 can be integrally rotated.

As shown in FIG. 6, as the first holder 20 rotates, the ball 28 is selectively engaged with any one of the neutral position 15N, the left turn position 15L or the right turn position 15R of the click groove 15, The rotation position of the 1 holder 20 is regulated to either of these. However, since the second holder 30 rotates together with the first holder 20, such a mechanism does not exist.

Next, the operation of this embodiment will be described. In FIG. 1, when the lever 40 is rotated from the neutral position, for example, in the right turn direction, the holders 20 and 30 rotate together. At this time, on the first holder 20 side, as shown in FIG. 6, first, the protrusion 44 of the main body 41 is rotated from the neutral position N to the right turn position R.

Along with this, the edge 22a of the cam hole 22 is pushed by the protrusion 44, so that the first holder 20 also rotates clockwise in the drawing, and the ball 28 turns right from the neutral groove 15N of the click groove 15. Moving to the groove 15R, stopping in the right turn state, the turn signal circuit is switched so that the turn signal on the right turn side lights up.

When the hand is released from the lever 40 in this state, the lever 40 automatically returns to the neutral position with the first holder 20 left in the right-turned state, and the protrusion 44 also moves to the neutral position shown by the solid line in the figure. Return, and then extend the side 2 of the cam hole 22
2b is located.

When the main body 41 is pushed in, the tip of the protrusion 44 pushes the inclined side 22b, so that the first holder 2
0 receives a force to return to the neutral position by rotation, and the first holder 20 rotates in the counterclockwise direction to return to the neutral position,
The ball 28 is canceled by moving from the right turn groove 15R of the click groove 15 to the neutral groove 15N and stopping.
The left turn side is also subjected to the same procedure.

Along with the rotation of the first holder 20, the second holder 30 is also rotated by the cam mechanism of the projection 43 and the cam hole 32, and the movable contact 24 is brought into contact with and separated from the second terminal 62. , For example, the position circuit is switched, but as is apparent from FIG. 4, the engagement protrusions 33a and 35a are
However, since it engages with the same 23a and 25a on the first holder 20 side and rotates integrally with the first holder 20, the holding mechanism on the second holder 30 side can be omitted.

Therefore, according to the present embodiment, the two circuits can be simultaneously operated by one lever 40, and the number of levers can be reduced, so that the complexity of the operation can be eliminated and, in the conventional case, they are provided separately. Switch that can be integrated into one. Moreover, since the first holder 20 and the second holder 30 rotate with the line L connecting the lever 40 and the guide member 50 interposed therebetween, uneven wear at each contact portion is reduced.

Next, a second embodiment will be described. 10 to 13 are views showing the first holder 20 and the second holder 30 according to the second embodiment, FIG. 10 is a view of the first holder 70 corresponding to FIG. 6, and FIG. 11 is a cross section taken along line 11-11 of FIG. It is a figure. 12 is a view of the second holder 80 corresponding to FIG. 8, and FIG. 13 is a sectional view taken along line 13-13 of FIG.

As shown in FIGS. 10 to 13, the mounting step portion 7
3 is provided with an engagement pin 73a, and the attachment step portion 83 is provided with an engagement hole 83.
a is provided and the engaging pin 73a is fitted in the engaging hole 83a, and the engaging pin 7 of the mounting step portion 74 also provided in the same manner.
By fitting 4a into the engaging hole 84a of the mounting step portion 84, the first holder 70 and the second holder 80 can be integrally rotated.

In this way, the first holder 70 and the second holder 80 can be engaged more reliably. Moreover, when the two are combined, they will not shift laterally relatively,
The handleability during assembly can be improved.

The present invention is not limited to this embodiment and can be applied in various ways. For example, even if the second holder 30 is not provided with the cam hole 32, the cam mechanism is only on the first holder 20 side, and the engagement with the protrusion 43 is omitted, the interlocking relationship between the first holder 20 and the second holder 30 Since the same function can be achieved as long as is maintained, the cam mechanism and the holding mechanism on the second holder 30 side can be omitted. However, the cam mechanism may be separately provided in the first holder and the holding mechanism may be provided in the second holder, or the arrangement may be reversed.

Further, the first holder 20 and the second holder 3
When 0 is not engaged and the cam mechanism on the second holder 30 side is omitted and the second holder 30 and the lever 40 are simply integrally rotated, only the first holder 20 side has a push cancel mechanism. Since the second holder 30 side follows the lever 40, it can be used for a flashing circuit of a head lamp or a stop lamp that does not require a push cancel mechanism, and a horn circuit or the like if necessary.

Further, if the inclined side 32b of the cam hole 32 is changed so as to be orthogonal to the other side 32a to form a square or rectangular hole, the first holder 20 has a push cancel mechanism, but the second holder. 30 is left behind when the push of the first holder 20 is cancelled. Therefore, it is suitable for a turn signal switch for an automatic cancel mechanism.

[0032]

The present invention is different from the conventional push cancel switch in that the terminal is provided in the case and connected to either the turn signal circuit or another circuit, and the first terminal is provided in the terminal base. The second terminal is connected to another circuit, the holder is composed of the first and second holders, and the first holder is provided on the side of the first terminal with the line connecting the lever and the guide member interposed therebetween. A second holder is arranged on the terminal side, and each of these holders is configured to be rotated by the rotation of the lever or the other holder.

Therefore, since the first and second holders are rotated by levers or other holders, the movable contact of each holder comes into contact with and separates from the first terminal and the second terminal, and the winker circuit and other circuits are separated. Switching can be done with one lever, and switches that are originally provided separately can be integrated into the case of a single switch.

Since the two circuits can be operated by one lever, the number of levers can be reduced and the operation can be simplified, so that the number of parts can be reduced and good operability can be obtained. Moreover, it is possible to provide a small switch that can operate two circuits.

Furthermore, since the two holders rotate on opposite sides of the line connecting the lever and the guide member, uneven wear of the contact portion is reduced and good operability can be maintained for a long time.
And the life of the switch can be measured.
