BACKGROUND OF THE INVENTION
The present invention relates to an operation lever provided in a vehicle having a handle bar so as to be swingable in the vicinity of a grip at the tip of the handle bar.
[0002]
[Prior art]
In recent years, snowmobiles capable of traveling on snow have been used as vehicles having other roles such as motor sports and entertainment in addition to the role of carrying luggage and people, and have been widely spread. Such a snowmobile is provided with a handlebar for steering, and grip grips for a driver to grip while traveling are attached to the front ends of both sides.
[0003]
Among such grip grips, a throttle operation lever that can be operated by the driver with the thumb of the right hand is swingably provided in the vicinity of the grip grip attached to the right side, while in the vicinity of the grip grip attached to the left side. A brake operation lever that can be operated by grasping the driver is swingably provided. Of these, when the brake operation lever is swung from the neutral position in the direction closer to the gripping grip, the movable contact interlocking with it and the fixed contact fixed to the handlebar come in contact and turn on, and the snowmobile A brake light mounted on the rear was lit.
[0004]
[Problems to be solved by the invention]
However, in the conventional lever switch such as the brake operation lever, only the operation in the direction close to the gripping grip can be performed from the neutral position, and therefore only one switch can be provided for one operation lever. could not. For example, the above-described brake operation lever also functions exclusively as an operation lever for a switch that lights a brake light, and a separate operation lever or a switch knob is required to perform switching operation of other switches.
[0005]
Therefore, only the necessary number of switches are provided with operation levers or switch knobs, which increases the number of components to be attached to the vehicle and increases the manufacturing cost. However, an operation lever such as a brake operation lever attached in the vicinity of the grip grip is located very close to the driver's hand and can be operated while holding the grip grip. Since the operability is better than that of a switch, it is desirable to use this to provide a composite switch.
[0006]
The present invention has been made in view of such circumstances, and it is possible to reduce the manufacturing cost by reducing the number of parts related to the switch in the vehicle, and to improve the operability for various equipment mounted on the vehicle. Is to provide.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The lever switch according to the present embodiment is composed of a brake operation lever that is swingably attached in the vicinity of the left grip grip of the handlebar in the snowmobile, and as shown in FIG. A brake operating lever 5 is attached to a locking tool 4 fixed at a position adjacent to the lever.
[0011]
The locking tool 4 is formed with a shaft 3 extending in a direction perpendicular to the paper surface of the drawing, and a brake operation lever 5 can swing in two directions around the shaft 3. In other words, the brake operation lever 5 can swing both in the a direction close to the grip 2 from the neutral position (the state shown in the figure) and in the b direction opposite to the a direction. is there.
[0012]
When the brake operation lever 5 is swung in the direction a, the brake is operated by pressing the brake pad of the wheel against the disc as in the conventional case. Reference numeral 6 in the figure denotes an oil chamber attached to the upper surface side of the locking tool 4 and filled with brake oil. The oil chamber 6 is moved by swinging the brake operation lever 5 in the direction a. The brake oil is pushed out to the wheel side, and the brake pad is pressed against the disc. Reference numeral 7 denotes a lock member for locking the brake operation lever 5 in a brake-operated state and maintaining the brake state.
[0013]
Further, as shown in FIGS. 2 and 3, a composite switch 8 having an arm portion 9 that is rotatable about the shaft 3 is attached to the lower surface side of the locking tool 4. A convex portion 9 a is provided at the tip of the arm portion 9 of the composite switch 8, and the convex portion 9 a is fitted in a concave portion 5 a formed in the brake operation lever 5. When the swinging operation is performed, the arm portion 9 is also configured to be able to rotate in conjunction with it.
[0014]
As shown in FIG. 4, the composite switch 8 includes a resin case 10 and a cover 11 as a casing, and a boss portion 9 b integrally formed with the arm portion 9 is formed in a part of the case 10. A hole 10a through which can be inserted is formed. The arm portion 9 is assembled by inserting the boss portion 9b from the outside of the case 10 into the hole 10a, and the first rotating member 12 and the second rotating member 13 are fitted into the boss portion 9b.
[0015]
That is, through holes 12a and 13a are formed at substantially the center of the first rotating member 12 and the second rotating member 13, and by fitting the through holes 12a and 13a to the boss portion 9b, Is configured to rotate around the boss 9b. Further, a male screw 9ba is formed at the tip of the boss portion 9b, and the male screw 9ba is fitted in the state where the torsion spring 14, the second rotating member 13 and the first rotating member 12 are fitted to the boss portion 9b. A nut 18 is screwed to 9ba to connect these components.
[0016]
A through-hole penetrating in the axial direction is formed at the center of the boss portion 9b, and the shaft 3 is inserted into the through-hole, and the tip side of the shaft 3 is a nut N (see FIGS. 2 and 3). It is assembled by screwing in. Therefore, the arm portion 9, the first rotation member 12, and the second rotation member are configured to be rotatable about the shaft 3.
[0017]
The torsion spring 14 interposed here is arranged so that one end of the torsion spring 14 is in contact with the second rotation member 13 and the other end is in contact with the case 10 so that the second rotation is assembled in the case 10. The member 13 is always urged clockwise (clockwise). The second rotating member 13 has an action portion 13b that protrudes to the side and a convex portion 13c that protrudes upward, and the dimmer switch 16 described later can be operated at the tip of the action portion 13b. ing.
[0018]
On the side of the first rotating member 12, a groove 12b formed in an arc shape and an accommodation hole 12c for accommodating the movable contact 17 via a spring 18 are formed. The protrusion 13c of the moving member 13 is assembled so as to be fitted. On the other hand, a terminal block 15 is fitted in the recess 11a of the cover 11, and the movable contact 17 can be brought into contact with or separated from a fixed contact (not shown) formed on the back surface of the terminal block 15. ing. The movable contact 17 and the fixed contact of the terminal block 15 corresponding to the movable contact 17 constitute a first switch according to the invention, and the brake light at the rear of the vehicle can be turned on when these contacts come in contact and turn on.
[0019]
More specifically, when the brake operation lever 5 is in the neutral position, as shown in FIG. 5, the convex portion 13 c of the second rotating member 13 abuts on one end of the groove 12 b of the first rotating member 12. When the brake operating lever 5 is swung in the direction a, the arm portion 9 is also rotated, and the first rotating member 12 is also rotated accordingly. At this time, since the rotation of the second rotating member 13 is restricted by the inner wall of the case 10, only the first rotating member 12 is rotated, and the state shown in FIG. Contact with 15 fixed contacts.
[0020]
That is, when the brake operation lever 5 in the neutral position is swung in the direction in which the brake operation lever 5 approaches the grip grip 2 (direction a), the first switch is switched and the brake light mounted on the vehicle can be turned on. It is. After the swing operation, the brake operation lever 5 is returned to the neutral position by a return spring (not shown), and the first rotating member 12 is also returned to the original position (state shown in FIG. 5).
[0021]
On the other hand, the dimmer switch 16 has a movable contact 16a on the upper surface and a movable pin 16b on the lower surface, as shown in FIG. The tip of the movable pin 16b is inserted into a heart cam 10b formed in the case 10, and can be moved in and out along the cam surface (bottom surface gradient) of the heart cam 10b, and is attached in a predetermined direction by a coil spring 16c. It is energized. The heart cam 10b is slidable to the right and left (in the direction of the arrow in FIG. 8) with respect to the case 10, and the movable pin 16b is shown in FIG. And the L position can be locked.
[0022]
When the dimmer switch 16 with the movable pin 16b inserted into the H position is pressed to the L position side, the heart cam 10b slides to the left and right, and the movable pin 16b moves in and out to the L position. The dimmer switch 16 is stopped at that position. When the dimmer switch 16 is pressed to the H position side from that state, the heart cam 10b slides to the left and right, and the movable pin 16b moves in and out to reach the H position, and the dimmer switch 16 is stopped at that position.
[0023]
However, when the dimmer switch 16 is in the H position, the movable contact 16a comes into contact with a predetermined fixed contact formed on the back surface of the terminal block 15, and the vehicle headlamp is set to a high beam (front illumination). When the dimmer switch 16 is in the L position, the movable contact comes into contact with a predetermined fixed contact formed on the back surface of the terminal block 15, and the vehicle headlamp is configured to be a low beam (downward illumination). .
[0024]
Here, the dimmer switch 16 and the fixed contact of the terminal block 15 corresponding to the movable contact 16a constitute the second switch of the invention. As a result, as shown in FIG. 5, when the brake operation lever 5 in the neutral position is swung in the direction (b direction) opposite to the switching operation direction (a direction) of the first switch, the arm portion 9 also rotates. Accordingly, the second rotating member 13 also rotates.
[0025]
At this time, since the rotation of the first rotating member 12 is restricted by the inner wall of the case 10, only the second rotating member 13 rotates, and the state shown in FIG. Then, the movable contact 16a is brought into contact with a fixed contact on the low beam side (formed on the back surface of the terminal block 15). In this way, the headlamp of the vehicle is a low beam (downward illumination).
[0026]
In this state, since the movable pin 16b is locked at the L position of the heart cam 10b (see FIG. 8), the dimmer switch 16 continues to be positioned on the low beam side, while the second rotating member 13 Returns to its original state by the urging force of the torsion spring 14, and the brake operation lever 5 also returns to the neutral position. That is, although the brake operation lever 5 returns to the neutral position, the dimmer switch 16 is maintained in the state after the operation, so that the headlamp remains at the low beam.
[0027]
When the brake operating lever 5 in the neutral position is again swung in the direction b, the action portion 13b of the second rotating member 13 presses the dimmer switch 16 again, and the movable pin 16b in the L position is moved to the H position. Move to position. Accordingly, the dimmer switch 16 moves to the high beam side, so that the movable contact 16a comes into contact with a predetermined fixed contact on the terminal block 15, and the vehicle headlamp is set to the high beam (front irradiation).
[0028]
Even in such a state, since the movable pin 16b is locked at the H position, the dimmer switch 16 continues to be positioned on the high beam side, while the second rotating member 13 and the brake operation lever 5 remain at the original positions. Return to position. In this manner, the vehicle headlamp can be switched between the high beam and the low beam each time the brake operation lever 5 is swung in the direction b.
[0029]
In the above-described embodiment, since the operation direction of the brake operation lever 5 is opposite to each other (direction a and direction b), the swing operation of the brake operation lever 5 and the rotating portion (arm) of the composite switch 8 are performed. The rotation of the portion 9, the first rotation member 12 and the second rotation member 13) can be made the common shaft 3 (including the boss portion 9b), and compared with a component provided with a separate shaft. The number of points can be reduced and the configuration can be simplified.
[0030]
In this embodiment, the operation direction for switching the second switch is opposite to the operation direction for switching the first switch (direction a), but in a direction different from the direction a. Any direction may be used as long as the second switch is switched.
[0032]
However, the brake operation is usually performed at a predetermined timing that is not arbitrary (the operation timing is not arbitrary when stopping when turning or avoiding danger), whereas the switching operation of the headlamp is arbitrary timing Since these switches do not necessarily have to be turned on at the same time, the combination of switches as in this embodiment is most preferable. Even if the second switch constitutes a dimmer switch, the present invention is not limited to the configuration of the present embodiment, and the vehicle headlamp may be switched by another configuration.
[0033]
Certainly theory, applicable operating lever is not limited to snowmobile, other vehicles equipped with a handlebar (motorcycle, ATV, snowmobile, PWC, etc.) as being.
[0034]
【The invention's effect】
According to the invention of claim 1, since the first switch and the second switch can be switched by swinging one operation lever in different directions, the number of parts related to the switch in the vehicle can be reduced. Thus, the manufacturing cost can be reduced and the operability for various equipment mounted on the vehicle can be improved.
[0035]
Furthermore, since the second switch is switched when the operation lever is swung in a direction substantially opposite to the operation direction in which the first switch is switched, the shafts of the operation lever can be made common and integrated. The number of points can be further reduced and the configuration can be simplified.
[0036]
Furthermore, according to the invention of claim 1 , when the first switch is switched on, the brake light mounted on the vehicle is turned on, and when the second switch is switched, the headlamp mounted on the vehicle is switched between the high beam and the low beam. since switching operation between, it can be selectively used with these first and second switches good. In other words, the brake operation is usually performed at a predetermined timing that is not arbitrary (the operation timing is not arbitrary when stopping when turning or avoiding danger), whereas the switching operation of the headlamp is arbitrary. These switches do not necessarily have to be turned on at the same time.
[0037]
According to the invention of claim 2 , since the first switch and the second switch are respectively switched by the first rotating member and the second rotating member, a reliable switching operation can be performed, and the reliability of the apparatus is improved. Can be improved.
