DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lever switch for a vehicle, and an object of the present invention is to provide a lever switch for a vehicle by pivoting operation levers on both sides of a column body, and installing a switch device equipped with a plurality of switches on the column body. When installed on one side of the body, each switch of the switch device is configured so that it can be selectively opened and closed by both operating levers, and the switch that is opened and closed more frequently is operated by the operating lever on the side that is easier to operate. To provide a lever switch for a vehicle capable of improving operability.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. Reference numeral 1 denotes a column body fixed to a pipe 3 through which a steering shaft 2 passes through a fastening fitting 4, and a hole 5 is formed in the center of the column body for allowing the upper end of the steering shaft 2 to protrude. An operating lever 6 is pivotally supported on the left side of the column body 1 by a shaft 7 so as to be rotatable in the vertical direction (in the direction of arrow A and counter-arrow A in FIG. 2), and is also formed on the right side of the hole 5. A bracket 9 is rotatably supported in the bearing hole 8 via its shaft cylindrical portion 9a in the vertical direction (in the direction of arrow B and counter-arrow B in FIG. 2). An operating lever 10 is pivotably supported by a shaft 11 so as to be rotatable in the front side and in the opposite direction (in the direction of arrow C and counter-arrow C in FIG. 1). Therefore, the operating lever 10
is rotated independently in the direction of arrow C and counter-arrow C, and also rotates in the direction of arrow B and counter-arrow B together with the bracket 9.
It can also be rotated in any direction. Reference numeral 12 denotes a switch case disposed on the back right side of the column body 1, which houses left and right turn signal switches and hazard switches (none of which are shown), a contact holder 13 for turns, and a contact holder 14 for hazards. It has a built-in. The contact holder 13 for turning has a protrusion 13a engaged with a groove 15 formed in the lower part of the bracket 9, and the bracket 9 is aligned with the arrow B and the opposite arrow B.
When the switch is rotated in the direction, it reciprocates accordingly and selectively closes each right or left turn signal switch. Further, the hazard contact holder 14 has an operating portion 14a projecting upward from the column body 1, and when the operating portion 14a is pulled upward, it slides in the same direction to close the hazard switch. In FIG. 1, reference numeral 16 is a knob that is provided at the tip of the operating lever 10 and has a built-in wiper switch.The rotary knob 17 turns on and off the wiper and changes the operating speed, and the push button 18 turns on and off the wiper. A cord 19 is extended from the wiper switch and pulled out from the operating lever 10. In FIGS. 1 and 2, reference numeral 20 indicates a moderation mechanism for holding the bracket 9 in the neutral position shown in the drawings and the upper and lower positions on both sides thereof, and 21 indicates a steering wheel return mechanism (not shown) for holding the bracket 9 in the upper and lower positions. This is a cancel mechanism for returning to the neutral position by operation.

Now, reference numeral 22 denotes a switch device for light control, for example, which is disposed on one side of the column body 1, for example, on the back left side.
The structure and the related structure with both the operating levers 6 and 10 will be explained in detail. That is, 23 is a removable lid 2
4 and is attached to the column body 1 by screws 25. Inside this is a small switch 2, as shown in FIG.
6 and a daylight switch 27 which also serves as a passing switch are arranged in parallel. The small switch 26 includes a fixed contact piece 26a connected to a battery (not shown) and a movable contact piece 26b connected to a small lamp such as a side lamp or a tail light.
The daylight switch 27 is composed of both a main switch 28 and a changeover switch 29, and the main switch 28 is a fixed contact piece 2 connected to a battery.
The changeover switch 29 consists of a fixed contact piece 29a connected to the low beam side of the headlight, a fixed contact piece 29b connected to the high beam side of the headlight, and a movable contact piece 28b. It consists of two corresponding movable contact pieces 29c and 29d, and the movable contact pieces 28b, 2 of the main switch 28 and the changeover switch 29
9c and 29d extend integrally from one conductive plate 30. Therefore, on the condition that the main switch 28 is closed, the contact piece 2 of the changeover switch 29
When the contact piece 29c is brought into contact with the contact piece 29a, the headlight is lit on the low beam side, and when the contact piece 29d is brought into contact with the contact piece 29b, the headlight is turned on on the high beam side. 31 is a fixed shaft attached to the case 23, and a small switch 2 is attached to this.
A cylindrical cam 32 serving as an actuator for opening and closing the main switch 6 and the main switch 28, and a cylindrical cam 33 for opening and closing the main switch 28 and the changeover switch 29 are rotatably supported. protrusions 32a, 32b and 33
a, 33b, 33c, and 33d are provided intermittently in a protruding manner. The cylindrical cams 32 and 33 are butted against each other on the movable contact piece 28b of the main switch 28. In this embodiment, the cylindrical cam 32 is operated by the operating lever 6 on the side where the switch device 22 is disposed, and the cylindrical cam 33 is operated by the operating lever 10 on the opposite side from the side where the switch device 22 is disposed. This is the basic idea. That is, a spiral groove 34 is formed in the cylindrical cam 32, and a protrusion 6a formed at the tip of the operating lever 6 engages with this spiral groove 34, so that the operating lever 6 is moved in the direction of the arrow A and the opposite direction. When rotated in the direction of arrow A, the projection 6a slides within the spiral groove 34, causing the cylindrical cam 32 to rotate forward and backward. Then, when the operating lever 6 is rotated one step in the direction of arrow A from the off position shown by the solid line in FIG. When the protrusion 32a brings the contact piece 26b of the small switch 26 into contact with the contact piece 26a, and the operating lever 6 is further rotated one step in the direction of arrow A to set it to the second on position shown by the broken line, the cylindrical cam 3
2 is further rotated one step in the direction of arrow D, and the protrusion 32a,
32b, each of the contact pieces 26b and 28b of the small switch 26 and the main switch 28 are connected to the contact piece 2.
6a and 28a. Note that 35 is a moderation mechanism that holds the operating lever 6 at the off position, first and second on positions.

On the other hand, 36 is a displacement transmission device that converts the rotational displacement of the operating lever 10 in the arrow C and counter-arrow C directions into the rotational displacement of the cylindrical cam 33 and transmits the rotational displacement. The rotational displacement in the direction is first converted into a linear movement of the connecting rod 39 via the rod 37 and the swinging lever 38, and this linear movement of the connecting rod 39 is converted into a linear movement of the connecting rod 39 by the rack 40 formed at the tip of the connecting rod 39 and the cylindrical cam 33. The configuration is such that the rotational displacement of the cylindrical cam 33 is converted by a pinion 41 formed at one end of the cylindrical cam 33. That is, the rod 37 is housed together with the compression spring 42 in the cylindrical portion 9a of the bracket 9, and reciprocates in conjunction with the rotation of the operating lever 10 in the directions of arrow C and counter-arrow C. The swing lever 38 is rotatably supported on the column body 1 via a stepped screw 43, and has an inclined portion 38a formed at one end and a long hole 44 formed at the other end. A connector 39a protruding from the base end of the connecting rod 39 is inserted into the elongated hole 44.
A rising part 39b is formed at the tip of the connecting rod 39, and this rising part 39b is connected to the lid 2 of the case 23.
The compression spring 46 is housed in a cavity 45 formed on one side of the connecting rod 39, and the compression spring 46 urges the connecting rod 39 in the direction of arrow E. Move lever 38 to arrow F
The inclined portion 38a is rotated in the direction of the rod 3.
It is in sliding contact with the lower end of 7. When the operating lever 10 is set to the low beam position shown by the solid line in FIG. 1, the displacement transmitting device 36 is in the state shown in FIG. The contact piece 29c of the changeover switch 29 is brought into contact with the contact piece 29a. Then, when the operating lever 10 is rotated in the direction opposite to arrow C and set to the high beam position shown by the two-dot chain line in FIG.
Since the connecting rod 39 moves in the direction of arrow G due to the spring force of the compression spring 46, the connecting rod 39 rotates the swinging lever 38 in the direction of arrow F and moves in the direction of arrow E due to the spring force of the compression spring 46. The pinion 41 rotates the cylindrical cam 33 in the direction of arrow H, and the cylindrical cam 33 switches between the changeover switch 2 and
The contact piece 29c of No. 9 is separated from the contact piece 29a, and the contact piece 29d is brought into contact with the contact piece 29b by the protrusion 33b. Further, when the operating lever 10 is rotated in the direction of arrow C and set to the pushing position shown by the broken line in FIG.
8a and moves in the direction opposite to arrow G against the spring force of the compression spring 42, the swinging lever 38 receives a component force in the direction opposite to arrow F at the inclined portion 38a and rotates in the same direction. As a result, the connecting rod 39 moves in the direction opposite to the arrow E against the spring force of the compression spring 46, and the rack 40 and pinion 41 rotate the cylindrical cam 33 in the direction opposite to the arrow H.
Based on this rotation, the cylindrical cam 33 moves the protrusions 33c,
33d, the contact piece 28b of the main switch 28 and the contact piece 29d of the changeover switch 29 are brought into contact with the contact pieces 28a and 29b, respectively. 47 is a moderation mechanism of the operating lever 10, and its moderation holding plate 48 has a recess 4 at the top.
9 and no such recess is formed in the lower part. Therefore, when the operating lever 10 is rotated to the high beam position, the concave portion 49 remains even when the user releases the operating lever 10.
However, when the high beam position is rotated to the passing position, when the hand is released, the spring force of the compression spring 42 automatically returns to the low beam position.

Next, the operation of the above configuration will be explained. At dusk, etc.
When the operating lever 6 is set to the first on position,
The cylindrical cam 32 is rotated in the direction of arrow D, whereby the contact piece 26b of the small switch 26
6a is closed and small lamps such as side lamps and tail lamps are turned on. Furthermore, when the operating lever 6 is set to the second on position at night, etc., the circular cam 32 is further rotated in the direction of arrow D, which causes the contact between the contact pieces 26b and 26a of the small switch 26 and between the contact pieces 26a and the main switch. 28 contact pieces 28b and 28a are closed to light the small lamp and headlight. In this case, the headlights are turned on in either the low beam or the high beam depending on the holding position of the operating lever 10. When the operating lever 10 is switched between the high beam position and the low beam position depending on the surrounding brightness or the presence or absence of an oncoming vehicle, the operating lever 10 is switched between the high beam position and the low beam position.
The rotational displacement of 0 is transmitted to the cylindrical cam 33 via the rod 37, the rotation lever 38, the connecting rod 39, the rack 40 and the pinion 41, and the cylindrical cam 33 rotates in the direction of arrow H or in the opposite direction of arrow H, As a result, the contact pieces 29d and 29b and the contact pieces 29c and 29a of the changeover switch 29 are alternately closed, and the headlights are alternately switched between high beam and low beam. Furthermore, when the operating lever 10 is switched to the passing position during overtaking, the rotational displacement of the operating lever 10 is converted into a rotational displacement of the cylindrical cam 33 in the opposite direction of the arrow H and is transmitted via the same transmission path as described above. As a result, the contact piece 28b of the main switch 28 and the contact piece 28a
and one contact piece 29d and one contact piece 29b of the changeover switch 29.
When the timer is closed, the headlights are turned on on the high beam side, and a passing signal for passing is performed.

As described above, according to this embodiment, the switch device 2
2. An operating lever 10 provided on the opposite side from the installation side.
The rotational displacement of the cylindrical cam 33 is converted into the rotational displacement of the cylindrical cam 33 by the rod 37, the swinging lever 38, the connecting rod 39, the rack 40, and the pinion 41. Even though the switch device 22 for light control must be placed on the left side of the column body 1 due to the provision of a turn signal switch and a hazard switch, it may be difficult to The daylight switch 27, which must be activated frequently when overtaking, can be operated using the easy-to-operate right operating lever 10, compared to a system in which the daylight switch 27 is also operated using the left operating lever 6. This greatly improves operability.

Next, another embodiment of the present invention will be described based on FIG. In this embodiment, the headlights are switched between low beam and high beam by rotating the right control lever toward you, and when the control lever is rotated and released, the spring automatically returns it to its original position. This is suitable for devices with a configuration in which That is, with the above configuration, the linking rod 39 of the displacement transmission device 36 moves in the direction of arrow J in conjunction with the manual rotation of the operating lever, and then immediately moves in conjunction with the return rotation of the operating lever by the spring. Therefore, in the configuration as in the above-mentioned embodiment, it is no longer possible to maintain the lighting state of the headlights at low beam or high beam. This embodiment can deal with such problems, and its configuration will be explained below. That is, 50 is a cylindrical cam that is fitted to the fixed shaft 31 and opens and closes the changeover switch 29, and 51 is a cylindrical cam that is fitted to the fixed shaft 31 and is connected to the connecting rod 39.
This pinion 51 is pressed against the cylindrical cam 50 by a compression spring 52 interposed between the pinion 51 and the case 23. Then, the cylindrical cam 50 and the pinion 51
A one-way clutch pawl 5 is attached to the butting end surfaces of the
3 and 54 are formed so that only rotation of the pinion 51 in one direction, that is, rotation in the direction of arrow K, is transmitted to the cylindrical cam 50. 55 is a compression spring 57 in a hole 56 formed in the fixed shaft 31.
This is a ball accommodated with the cylindrical cam 5.
When the pinion 51 fits into the recesses 58 intermittently formed in the cylindrical cam 50 and rotates in the direction opposite to the arrow K while riding over the pawl 53 of the cylindrical cam 50, the cylindrical cam 50
is held so that it does not follow the rotation of the pinion 51 in the opposite direction of arrow K.

When the right operating lever is operated, the connecting rod 39 moves continuously in the direction of the arrow J and the direction opposite to the arrow J to rotate the pinion 51 in the direction of the arrow K and the direction opposite to the arrow K. 54, only the rotation of the pinion 51 in the direction of arrow K is transmitted to the cylindrical cam 50. Therefore, each time the right operating lever is operated, the cylindrical cam 50 rotates one step at a time in the direction of arrow K, and the rotation of the cylindrical cam 50 one step at a time causes the contact piece 29c of the changeover switch 29 to be rotated one step at a time. Between the movable contact piece 29d and the fixed contact piece 29
The spaces between b are alternately closed. In FIG. 6, the same parts as those in FIG. 5 are given the same reference numerals, and detailed explanations are omitted. Even with this configuration, it is possible to obtain the same effect as the above-mentioned embodiment.

In each of the above embodiments, a turn signal switch and a hazard switch are provided on the right side of the column body, and a switch device for light control is provided on the left side. A switch device for light control is installed on the left side, a turn signal switch and a hazard switch are installed on the left side, and the cylindrical cam for operating the main switch and changeover switch of the daylight switch is directly operated by the operation lever on the right side. The cylindrical cams for operating the main switches of the small switch and the daylight switch may be operated by a left operating lever via a displacement transmission device. Furthermore, the switch device is not limited to one for light control, but may be for other controls such as a wiper.

As explained above, the present invention is a column body in which operation levers are respectively provided on both sides of the column body, and a switch device equipped with a main switch and a changeover switch is provided on one side of the column body. An actuator provided corresponding to one of the switches is operated by one of the operation levers on the side where the switch device is installed to open and close the one switch, and the other switch of the main switch and the changeover switch is opened and closed. By configuring the corresponding cylindrical cam to be operated by the other operating lever via the displacement transmission device, the switch that opens and closes more frequently can be operated by the operating lever on the side that is easier to operate. To provide a lever switch for a vehicle that can significantly improve operability.
