Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motorcycle seat lock device. [0002] Conventionally, there is a motorcycle equipped with a seat lock key cylinder for locking a detachable or openable seat (seat seat). In the motorcycle of the road sports type shown in FIG. 6, a locking hook at a front end of a seat a on which a rider sits is locked to a frame b, and a lower surface of a rear end of the seat a is engaged with a seat lock key cylinder c. To lock the seat. In the conventional seat lock key cylinder c, the key cylinder main body c is attached to the rear frame e, or the vehicle is mounted with the hole d1 formed in the rear end of the cover d and the key hole c1 of the key cylinder c facing the hole d1. Was attached to the rear assist grip held by the person. At the time of locking, the striker comes out of the key cylinder body c to lock the seat. On the other hand, in the case of the American type motorcycle, the seats are conventionally all fixed, and there is no need to attach or detach the seats. Therefore, no seat lock key cylinder is provided. However, even with this type of motorcycle, it has been desired to be able to attach and detach the seat from the demand for improved storage and maintenance, and it has become necessary to employ a seat lock key cylinder. However, in the above-mentioned American type motorcycle, since there is neither a seat tail cover nor a rear grip, it is difficult to lay out the seat lock key Linder from the viewpoint of appearance and space. There was a problem. In order to prevent theft or tampering, in the case of a type having a seat tail cover, it is possible to take measures such as providing a key cylinder on the back side of the tail cover or providing a key hole cap. There was also a problem that such measures could not be established with the American type. As for the seat lock device of a motorcycle, the applicant has already proposed a device in which a striker for locking the rear end of the seat and a key cylinder are provided separately and connected by a Bowden wire. (JP-A-4-
372483). However, this technology discloses a scooter type motorcycle having a seat tail cover provided with a seat lock, and cannot solve the above problem. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and the layout of the seat lock sealer can be appropriately performed in terms of appearance, space, and prevention of theft. An object of the present invention is to provide a motorcycle seat lock device that can sufficiently prevent theft and mischief. SUMMARY OF THE INVENTION The present invention relates to a seat lock device for locking a seat of a motorcycle. In the seat lock device, a key cylinder portion is fixed to a mounting bracket of a pillion footrest, and the key lock portion is provided. <br/> are those striker portion of Sunda over portion and another body is opened, locking the sheet in operation by the key to a key cylinder unit, be one which tilts in a direction along the vehicle body at the time of folding pillion footrest , The key hole of the key cylinder part with the pillion footrest at the time of the folding in side view

According to the first aspect of the present invention, the key cylinder portion of the seat lock device is fixed to the mounting bracket of the pillion footrest, and the striker portion separate from the key cylinder portion is operated by a key operation on the key cylinder portion. The key-linker and the striker can be attached without any layout problems. [0010] Further, the key cylinder portion is provided on a portion where the pillion footrest tilts in a direction along the vehicle body when folded, and the position of the key hole of the key cylinder portion overlaps with the pillion footrest when folded in side view. Therefore, theft and tampering can be effectively and reliably prevented without taking special measures against theft or tampering in the key hole of the key cylinder. Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an explanatory view of a motorcycle on which a seat lock device 32 according to an embodiment of the present invention is mounted, FIG. 2 is a side view of a main part of a mounted state of the seat lock device 32, FIG. FIG. 5 is an enlarged view of FIG. As shown in FIG. 1, the motorcycle is of the American type. The main frame 10 for suspending the engine 8 is of a cradle type, and a tank rail 14 extends obliquely downward from the head pipe 12,
Connected to rear frame 16. A fuel tank 18 is fixed across the tank rail 14, and a pivot frame 20 is provided to extend downward substantially from the rear end position of the fuel tank 18 of the tank rail 14.
The rear fender 22 is fixed to the rear frame 16 so as to cover above the rear wheel 26. A front seat (driver's seat) 24a is detachably provided from the rear end of the tank rail 14 to the upper part of the rear frame 16, and the front portion of the front seat 24a is provided at the upper edge of the tank rail 14. The rear part of the rear fender 22 is formed in a shape of a circular arc along the upper surface of the rear fender 22 and is formed in a rear upward inclination. Further, a rear seat (pillion seat) 24b is placed and fixed on the upper part of the rear fender 22. A pillion footrest 28 is fixed to the center of the rear frame 16 in front of the rear wheel 26 by a mounting bracket 30 so as to be foldable. That is, as shown in detail in FIGS. 4 and 5, the mounting bracket 30 projects rearward and is fixed to the rear frame 16 by welding.
The mounting bracket 30 includes a pillion footrest 28.
Is mounted and fixed. In the pillion footrest 28, a footrest member 28b as a footrest member is rotatably connected to the support shaft 28a. The footless member 28b
At the time of use, as shown by reference numeral 28b1 in FIG. 4 and FIG. 5, the state of extending toward the side of the vehicle body is a state in which the seated occupant can put his feet. Further, at the time of folding, as indicated by reference numeral 28b2, the support shaft 28b is bent upward and tilted in a direction along the vehicle body. The connecting portion 28c between the support shaft portion 28a and the footrest member 28b is structured to maintain the above-mentioned use and folding. The seat lock device 32 of the embodiment locks the front seat 24a. The front seat 24a has a striker portion 32a (an engagement piece 32a1) in which an engagement hook provided on a bottom surface of a front end portion is engaged with the main frame 10 (tank rail 14), and a rear end portion is fixed to the rear frame 16 by a bridge member 34. Moves up and down)

The pillion footrest 28 tilts in a direction along the vehicle body when folded, and the key cylinder 32b1 of the key cylinder portion 32b is positioned such that the position of the key hole 32b1 overlaps the pillion footrest 28 when folded as viewed in side view. The part 32b was provided. Therefore, the position of the cylinder portion 32b is difficult to be understood by anyone other than the owner of the motorcycle, and theft and mischief can be effectively and reliably prevented without taking special measures against theft and mischief in the key hole 32b1 of the key cylinder portion 32b. The appearance of the key cylinder portion 32b can be improved by setting the key cylinder portion 32b on the back side (the vehicle body side) with the pillion footrest 28 folded. In addition, there is no dedicated bracket for mounting the key cylinder portion 32b, and since the mounting bracket 30 for the pillion footrest is also used, advantages in cost and space are great. Further, since the key cylinder portion 32b is located on the back side of the bracket 30, it is difficult to move the wire from the outside in the vicinity of the bracket 30, and the wire cable 32c runs along the back side of the frame 10, so that the wire is also from the outside. It is difficult to move the wire cable 32C, and therefore, it is possible to reliably prevent the wire cable 32C from being forcibly moved. In the above embodiment, an American type motorcycle has been exemplified, but the present invention can be applied to other types of motorcycles (sports type, racer type, scooter type, etc.). As described above, according to the present invention, the key cylinder unit and the striker unit can be mounted without any layout problem. Also, theft and mischief can be effectively and reliably prevented without taking special measures against theft and mischief in the keyhole of the key series. Furthermore, since the footrest is hidden when folded, the appearance can be improved. In addition, since there is no dedicated bracket for mounting the key cylinder portion and the mounting bracket for the pillion footrest is also used, there are great advantages in cost and space.
