Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a seat lock mechanism for a motorcycle in which a main switch having a seat lock locking / unlocking function is disposed near the front of a fuel tank.
[0002]
[Prior art]
In the motorcycle, the seat is configured to be openable and detachable in consideration of maintenance of various devices arranged below the seat, and the seat is locked and unlocked by the seat lock mechanism. Conventionally, since the key cylinder constituting the seat lock mechanism is provided separately from the main switch, the operation is also performed separately from the key operation of the main switch.
[0003]
[Problems to be solved by the invention]
However, if the key cylinder of the seat lock mechanism is provided separately from the main switch and the operation is performed separately from the key operation of the main switch as described above, the appearance parts such as the key cylinder increase and the cost increases. There was a problem that the appearance of the motorcycle was impaired and the operability was poor.
[0004]
In addition, if the main switch is provided with a seat lock opening / closing function, the distance from the main switch to the seat lock is long, so the seat lock wire connecting the two becomes long, which increases the operating load of the main switch. There may be a problem.
[0005]
In addition, since the seat lock wire is disposed at a position that can be reached from the outside, there is also a problem that it is difficult to ensure theft prevention.
[0006]
The present invention has been made in view of the above problems, and its object is to provide a seat lock mechanism for a motorcycle that can improve appearance and operability, reduce costs, and prevent theft. .
[0007]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, a main switch is arranged in the vicinity of the front of the fuel tank, and the direction in which the seat lock wire connecting the main switch and the seat lock is pulled out from the main switch is main. It is characterized by being substantially parallel to the direction of inserting the key into the switch.
[0008]
According to a second aspect of the present invention, in the first aspect of the present invention, a seat lock that is turned ON / OFF by a key operation of the main switch is arranged on the front side of the main seat.
[0009]
According to a third aspect of the present invention, in the first or second aspect of the invention, the portion of the seat lock wire that is pulled out from the main switch is guided through the L-shaped metal pipe in a side view to the rear of the vehicle body. The seat lock wire portion led out from the metal pipe is passed through the upper side of the main harness arranged in the longitudinal direction of the vehicle body along the main frame.
[0010]
Therefore, according to the first aspect of the present invention, since the direction in which the seat lock wire is pulled out from the main switch is made substantially parallel to the direction in which the key is inserted into the main switch, the seat lock wire limits the capacity of the fuel tank. Therefore, the necessary and sufficient capacity can be secured in the fuel tank. In addition, since the seat lock operation can be performed at the same time by the key operation of the main switch, the appearance parts of the motorcycle can be improved and the cost can be reduced by reducing the appearance parts, and the operability of the seat lock can be improved. it can.
[0011]
According to the second aspect of the present invention, since the seat lock is arranged on the front side of the main seat, the length of the seat lock wire connecting the seat lock and the main seat is shortened, and the operation load of the seat lock is reduced.
[0012]
According to the third aspect of the present invention, the portion of the seat lock wire that is pulled out from the main switch is passed through the L-shaped metal pipe when viewed from the side. Because it is protected by a metal pipe, it cannot be operated to release the seat lock, and the seat harness wire part led out from the metal pipe is arranged along the main frame in the longitudinal direction of the vehicle body. Similarly, the seat lock wire cannot be released by operating the seat lock wire from the outside, and theft can be reliably prevented.
[0013]

A steering shaft (not shown) is rotatably inserted into the head pipe 2. An upper end portion of the front fork 3 is supported on the steering shaft, and a front wheel 4 is rotatably supported on the lower end portion of the front fork 3. A handle bar 5 is attached to the upper end of the steering shaft.
[0016]
On the other hand, after the main frame 6 extends obliquely downward from the head pipe 2 toward the rear of the vehicle body in a side view, and the pair of left and right down tubes 7 extend obliquely downward toward the rear of the vehicle body in a side view, It is bent toward the rear of the vehicle body and extends substantially horizontally below the main frame 6 toward the rear of the vehicle body. The rear end portions of the main frame 6 and the down tube 7 are connected to a rear arm bracket 8 formed in an arc shape.
[0017]
Thus, a V-type two-cylinder engine 9 is housed and supported in a space surrounded by the main frame 6, the down tube 7 and the rear arm bracket 8, and between the cylinders 9 a and 9 b before and after the engine 9. A carburetor 10 is provided.
[0018]
A fuel tank 11 is supported on the main frame 6 above the engine 9, and a main seat 12 and a tandem seat 13 are respectively disposed behind the fuel tank 11.
[0019]
On the other hand, the rear arm bracket 8 is pivotally mounted by a front end pivot shaft 15 of the rear arm 14, and a rear wheel 16 is rotatably supported at the rear end portion of the rear arm 14. The rear arm 14 and the rear wheel 16 pivotally supported at the rear end of the rear arm 14 are suspended on the vehicle body side by a single rear cushion (not shown), and an impact from the rear wheel 16 is caused by a damping force generated in the rear cushion.

[0020]
Thus, the motorcycle 1 according to the present embodiment employs a belt drive system as a drive system, and is coupled to a pulley (not shown) coupled to the output shaft of the engine 9 and the rear wheel 16. A belt (not shown) is wound around the wheel pulley 17.
[0021]
Here, the details of the configuration of the seat lock mechanism according to the present invention will be described with reference to FIGS. 2 is a cutaway side view around the seat lock mechanism portion of the motorcycle, FIG. 3 is a side view of the main switch portion, FIG. 4 is a cutaway side view of the main seat portion, and FIG. 5 is a cross-sectional view taken along line AA in FIG. 6 is a plan view of the seat lock portion, FIG. 7 is a perspective view of the seat lock, and FIG. 8 is a cross-sectional view taken along line BB of FIG.
[0022]
In the present embodiment, as shown in FIG. 2, the main switch 18 is disposed behind the handle crown 19 and in the vicinity of the front of the fuel tank 11. As shown in FIG. 3, the seat lock integrated main switch 18 can be turned on and off by inserting a key 40 therein and turning on and off the seat lock 20 described later. This is mounted on the bracket 22 welded to the gusset 21 and is mounted so as to be inclined parallel to the head pipe 2.
[0023]
On the other hand, as shown in FIG. 4, the main seat 12 has an engaging projection 23 projecting rearward at the rear part thereof inserted into a hook 24 fixed on the vehicle body side from the front, and the front part thereof is connected to the vehicle body side. By locking the seat lock 20 fixed to the vehicle body, the vehicle is fixed to the vehicle body side and is locked.
[0024]
Thus, the seat lock 20 disposed on the front side of the main seat 12 and the main switch 18 are connected by a seat lock wire 25 as shown in FIG. A portion pulled out from 18 is passed through an L-shaped metal pipe 26 in a side view, and the direction from which the main switch 18 is pulled out is substantially parallel to the direction in which the key 40 is inserted into the main switch 18. The seat lock wire 25 that has passed through the metal pipe 26 is guided to the rear of the vehicle body, passed through the main harness 27 disposed in the vehicle longitudinal direction along the main frame 6, and connected to the seat lock 20.
[0025]
Here, the configuration and operation of the seat lock 20 will be described with reference to FIGS.
[0026]
The seat lock 20 has a case 28 opened upward, and an engagement claw 29 having an engagement groove 29a is pivotally supported by a shaft 30 and accommodated in the case 28. The engaging claw 29 is urged in the direction of arrow c in FIG. 8 (the seat lock releasing direction) by a return spring 31 wound around the shaft 30.
[0027]
A slider 32 is slidably fitted up and down below the engaging claw 29 in the case 28, and the slider 32 is always urged upward by a spring 33.
[0028]
Further, a lever 34 is pivotally mounted by a screw 35 in the case 28, the seat lock wire 25 is connected to one end of the lever 34, and the other end of the lever 34 is formed in the case 28. It faces the case 28 through the opened opening 28a and engages with a groove 32a formed in the upper portion of the slider 32 as shown in FIG.
[0029]
On the other hand, as shown in FIG. 5, a plate 37 formed by welding a U-shaped hook 36 is attached to the bottom plate 12a of the main seat 12 by left and right bolts 38. It projects substantially vertically below the plate 12a.
[0030]
Thus, in the seat lock state, as shown in FIG. 8, the upper portion of the slider 32 of the seat lock 20 is engaged with the protrusion 29b of the engagement claw 29, and the engagement claw 29 is shown by a solid line in FIG. As shown, the engagement groove 29a is held in a horizontally open state, and the hook 36 that engages with the engagement groove 29a of the engagement claw 29 is locked to lock the main seat 12 fixed. .
[0031]
In the seat lock state, as shown in FIG. 2, when the key 40 is inserted into the main switch 18 and turned, and the seat lock wire 25 is pulled in the direction of arrow a in FIG. 7, the lever 34 of the seat lock 20 pulls the screw 35. The end that turns in the direction of arrow b as the center and faces the case 28 pushes down the slider 32 against the urging force of the spring 33 as shown by a chain line in FIG. Then, the engagement between the slider 32 and the engagement claw 29 is released, and the engagement claw 29 is rotated about the shaft 30 in the direction of the arrow c (counterclockwise) in FIG. 8 by the urging force of the return spring 31. As shown by a chain line in FIG. 8, the end surface 29c stops when it abuts against the upper surface of the case 28. At this time, the engaging groove 29a of the engaging claw 29 opens obliquely upward. The engagement with the engagement groove 29a is released and the seat lock is released, and the main seat 12 can be removed in this state.
[0032]
As described above, in the present embodiment, the seat lock integrated main switch 18 is adopted, and the seat lock operation can be performed by the key operation of the main switch 18. The appearance of the motorcycle 1 can be improved and the cost can be reduced, and the operability of the seat lock 20 can be improved.
[0033]
Further, since the seat lock 20 is disposed on the front side of the main seat 12, the length of the seat lock wire 25 connecting the seat lock 20 and the main seat 12 is shortened, and the operation load of the seat lock 20 is reduced.
[0034]
Further, since the direction in which the seat lock wire 25 is pulled out from the main switch 18 is made substantially parallel to the direction in which the key 40 is inserted into the main switch 18 by the metal pipe 26, the seat lock wire 25 limits the capacity of the fuel tank 11. Therefore, the fuel tank 11 can have a necessary and sufficient capacity.
[0035]
Further, since the portion of the seat lock wire 25 that is pulled out from the main switch 18 is passed through the L-shaped metal pipe 26 in side view, the seat lock wire 25 remains connected to the metal pipe 26 even if a hand is inserted through the front opening of the fuel tank 11. Therefore, the seat lock 20 cannot be released by operating this, and the portion of the seat lock wire 25 that is led out from the metal pipe 26 is arranged along the main frame 6 in the longitudinal direction of the vehicle body. Since the upper side of the main harness 27 is passed, the seat lock wire 25 cannot be similarly operated from the outside to release the seat lock 20, and theft can be reliably prevented.
[0036]
【The invention's effect】
As apparent from the above description, according to the first aspect of the present invention, the direction in which the seat lock wire is pulled out from the main switch is substantially parallel to the direction in which the key is inserted into the main switch. However, the capacity of the fuel tank is not limited, and a necessary and sufficient capacity can be secured in the fuel tank. In addition, since the seat lock operation can be performed at the same time by the key operation of the main switch, the appearance parts of the motorcycle can be improved and the cost can be reduced by reducing the appearance parts, and the operability of the seat lock can be improved. The effect that it can be obtained.
[0037]
According to the invention of claim 2, since the seat lock is disposed on the front side of the main seat, the length of the seat lock wire connecting the seat lock and the main seat is shortened, and the operation load of the seat lock is reduced. An effect is obtained.
[0038]
According to the third aspect of the present invention, the portion of the seat lock wire that is pulled out from the main switch is passed through the L-shaped metal pipe when viewed from the side. Because it is protected by a metal pipe, it cannot be operated to release the seat lock, and the seat harness wire part led out from the metal pipe is arranged along the main frame in the longitudinal direction of the vehicle body. Similarly, the seat lock wire cannot be released from the outside by operating the seat lock wire from the outside, so that theft can be reliably prevented.
