[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a handle switch mounted adjacent to a grip grip at the end of a handlebar in a vehicle, and more particularly to a handle switch having an engine stop switch for forcibly stopping a vehicle engine.
[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]
In addition, a handle switch is fixed to the handle bar at a position adjacent to the grip grip, and various operations can be performed with the switch formed on the handle switch. For example, the right hand handle switch may be a worm switch for warming the driver's hand or finger by heating the grip grip or the throttle lever extending from the base end side of the grip grip, or forcing the engine An engine stop switch for stopping is formed.
[0004]
This engine stop switch operation knob (hereinafter referred to as the engine stop switch knob) is a push-type button switch with a relatively large switch knob so that the driver can operate it with gloves on. Often adopted. Thus, the engine can be stopped by reliably pressing the switch knob at the time of emergency stop, and erroneous operation can be prevented.
[0005]
[Problems to be solved by the invention]
However, in the above-described conventional handle switch, the angle at which the engine stop switch is attached to the switch case cannot be changed. Therefore, when steering with the handle bar to change the traveling direction, the engine is not attached to the driver's body. There was a risk that the stop switch knob would come into contact, causing the engine to stop unintentionally.
[0006]
In particular, in a vehicle such as a snowmobile used for motor sports or entertainment, while climbing up and down a steep slope or making one end of the handlebar close to or in contact with the driver's body to increase the steering angle Since traveling is performed, there is a high possibility that the engine stop switch knob will be erroneously operated. When the engine stops unintentionally in this way, there is a risk of falling if it is in the middle of climbing a steep slope or in the middle of a sharp turn.
[0007]
However, in order to prevent such an erroneous operation as described above, the handle switch itself can be rotated around the handlebar to adjust the mounting angle of the engine stop switch. Etc.) may rotate together, and the operability of the switch may deteriorate.
[0008]
In addition to the driver's physique, the ideal mounting angle at which the engine stop switch knob is difficult to contact the driver is the state of the snow surface (whether it is flat or a steep slope), and the driving state (increasing the steering angle). Therefore, it is not possible to set an ideal mounting angle in general, and it is necessary to change the mounting angle according to various circumstances during traveling.
[0009]
The present invention has been made in view of such circumstances, and makes it possible to change the mounting angle of the engine stop switch to prevent the engine from being erroneously stopped during traveling and to improve operability. The object is to provide a handle switch that can be used.
[0010]

The lower surface of the lower switch case 1b is formed in an arc shape as shown in the figure, and the grip warmer switch knob 3 and the thumb warmer switch knob 4 that perform a sliding operation along this shape are provided on both side surfaces of the lower switch case 1b. Is attached. That is, the grip warmer switch knob 3 and the thumb warmer switch knob 4 are connected to the above-described rollers via arc-shaped long holes formed on both side surfaces of the lower switch case 1b, and each of the grip warmer switch knobs 3 and 4 is connected along the long holes. When the switch knob is slid, a switching operation corresponding to the switch knob can be performed.
[0019]
Further, a pair of guide grooves 1bd extending in the sliding direction of the grip warmer switch knob 3 and thumb warmer switch knob 4 are formed on the front surface of the lower switch case 1b, and are guided by these guide grooves 1bd. The switch knobs 3 and 4 slide. On the surface between these switch knobs 3 and 4, a symbol (which may be a character) for displaying the operation contents of the switch section 3 and 4 is printed.
[0020]
On the other hand, as shown in FIG. 4, the upper switch case 1a is formed with a concave portion 1ac that opens upward. The upper portion of the bottom surface of the concave portion 1ac has an upper portion along the outer peripheral surface shape of the handle bar H. A convex arc shape 1ad is formed. Moreover, a plurality of through holes m1 to m6 and n1 to n6 are formed to penetrate from the side surface of the upper switch case 1a to the recess 1ac and to insert the pair of bolts Bb. The pair of screws Bb and the plurality of through holes m1 to m6 and n1 to n6 constitute the fixing means of the present invention.
[0021]
The engine stop switch knob 2 is for forcibly stopping the snowmobile engine by a driver's pressing operation, and is formed to protrude from the switch unit U. The switch unit U is provided separately from the switch case 1 and has an engine stop switch knob 2 and a fixed contact (not shown) that is switched by a pressing operation of the engine stop switch knob 2. Is inherent.
[0022]
Specifically, as shown in FIG. 5, the engine stop switch knob 2 has a proximal end 2b inserted into the inner case I of the switch unit U and is movable in the direction of the arrow in the figure. The movable contact 2a formed on the base end side 2b is moved or brought into contact with or separated from a fixed contact (not shown) fixed to the inner case I to form a predetermined switch circuit.
[0023]
In the figure, symbol O indicates an outer case of the switch unit U. On one side surface of the outer case O, locking holes U1 and U2 that can be screwed with bolts Ba are formed at predetermined positions, respectively. Has been. Moreover, the code | symbol C1 has shown the wiring code extended to a snowmobile side from a fixed contact.
[0024]
Here, when the engine stop switch knob 2 is pressed and the movable contact 2a is slid rightward in the figure, the fixed contact can be contacted to form a switch circuit to stop the engine, while the engine stop knob 2 When the movable contact 2a is slid in the left direction in the figure, the switch circuit is disconnected from the fixed contact. A rubber boot 6 is press-fitted and fixed between the switch unit U and the projecting portion of the engine stop knob 2 to prevent the switch unit U from being flooded while allowing the engine stop knob 2 to be pressed. Yes.
[0025]
The lower surface of the switch unit U is formed with an arcuate shape Ua corresponding to the arcuate shape 1ad of the upper switch case 1a, and the switch unit U is accommodated in the recess 1ac while matching the arcuate shape Ua with the arcuate shape 1ad. It is configured. Accordingly, the switch unit U can swing with respect to the switch case 1 by sliding along the outer peripheral surface in the arc shape 1ad.
[0026]
And after making switch unit U into arbitrary angles, the engine stop switch knob 2 formed in the said switch unit U can be set to arbitrary attachment angles by latching with screw Bb. That is, in FIG. 4, when the screw Bb is inserted into both of the through holes m1 and n1, the tip end side is screwed into the locking holes U1 and U2, and the engine stop switch knob 2 is locked, as shown in FIG. In the state of the symbol A, the mounting angle of the engine stop switch knob 2 can be set.

Further, when the screw Bb is inserted into any of the through holes m2 to m6 and n2 to n6 and the switch unit U is fixed as described above, the engine stop switch knob 2 in the state of symbols B to F in FIG. The mounting angle can be set. Therefore, if any one of the plurality of through holes m1 to m6 and n1 to n6 is arbitrarily selected and the screw Bb is inserted, the engine stop switch knob 2 can be fixed to the switch case 1 at an arbitrary angle. it can.
[0028]
As a result, the mounting angle of the engine stop switch knob can be made variable to prevent the engine from being erroneously stopped while the snowmobile is running, and the operability can be improved. Further, the switch unit U is separated from the switch case 1, and the engine stop switch knob 2 can be swung by sliding the switch unit U while matching the arcuate shapes Ua and 1ad formed thereon. Therefore, the engine stop switch knob 2 can be swung with respect to the switch case 1 with a simple configuration as compared with the one having a separate swing mechanism.
[0029]
As mentioned above, although this embodiment was described, this invention is not limited to this, For example, it replaces with several through-holes m1-m6 and n1-n6, and elongate holes m 'and n as shown in FIG. 'May be formed. If the insertion position of the screw Bb with respect to the long holes m ′ and n ′ is arbitrarily determined and the switch unit U is locked, the engine stop switch knob 2 can be fixed at an arbitrary mounting angle as in the above embodiment. can do.
[0030]
Thus, if the screw Bb is inserted into the long holes m ′ and n ′ and the switch unit U is locked, the mounting angle of the engine stop switch knob 2 can be set steplessly. It is easy to make the angle most suitable for the person's body shape and running state, and operability can be further improved. If a thumbscrew is used instead of the screw Bb, the mounting angle of the engine stop switch knob 2 with respect to the switch case 1 can be further facilitated.
