CONSTITUTION:A seat lock 8 mounted onto the bridge 7 of the rear tube 2 of a frame is connected by an operating cable 12 to a key cylinder 10 which is fitted on the side face of the frame so that it can be seen from the outside, a pipe 13 is welded to the rear tube 2 on its one side while the pipe vertically penetrating the tube, and the operating cable 12 is then inserted in the pipe 13.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat lock device for a motorcycle.

[0002]

2. Description of the Related Art In a motorcycle, a seat can be opened and closed or can be attached and detached, and a storage case or the like is provided below the seat. The seat can be locked by a seat lock, and the seat lock can be unlocked by operating a key cylinder, which is attached to the side surface of the frame with a control cable, to operate the key cylinder.

[0003]

The key cylinder is mounted so that it can be seen under the tail cover on the side of the frame, which is convenient for key operation, and a hand is inserted inside the tail cover to pull the operation cable. And you can unlock the seat lock without a key. For this reason, the guard plate is attached with bolts so that the hands cannot be put inside, and there is a disadvantage that the number of parts increases.

In view of the above point, the present invention operates the lower portion of the operation cable connecting the seat lock and the key cylinder through the pipe welded to the rear tube of the frame and allows the hand to be inserted inside the tail cover. An object of the present invention is to obtain a seat lock device for a motorcycle, in which the cable cannot be touched, the key cannot be unlocked without a key, theft can be prevented, the number of parts is small, and the cost can be reduced.

[0005]

In order to achieve the above object, the seat lock device for a motorcycle according to the present invention is mounted on the side of the frame and the seat lock mounted on the bridge of the rear tube of the frame. The key cylinders are connected with an operation cable, and the rear tube on one side is vertically penetrated to weld a pipe, and the operation cable is inserted into the pipe.

[0006]

[Operation] Since the lower part of the operation cable is inside the pipe, even if you can insert your hand inside the tail cover, the pipe interferes and you can not reach the operation cable. If not used, the seat lock cannot be unlocked and theft can be prevented. Further, the operation cable can be connected to the seat lock and the key cylinder with the shortest length, and the guard plate is not required, so that the cost can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The rear portions of the left and right rear tubes 2 of the frame 1 are covered with a tail cover 3, and a rear seat 4 is detachably attached to the upper side of the tail cover 3. The inside of the tail cover 3 is a storage case 5. A striker 6 is provided at a front portion of the rear seat 4 so as to project downward, and a seat lock 8 is attached to an upper surface of a bridge 7 connecting the left and right rear tubes 2. The striker 6 is locked by being locked by the seat lock 8.

A grip pipe 9 is fastened to the lower side of the rear tube 2 on one side, a key cylinder 10 is fastened to the front part of the grip pipe 9, and a key hole 11 of the key cylinder 10 is attached to a side surface of the frame 1. It is made convenient for key operation from the outside. Then, the seat lock 8 and the key cylinder 10 are connected by the operation cable 12, and the seat lock 8 is unlocked by the key cylinder 10 via the operation cable 12.

Then, the rear tube 2 is passed through the upper portion of the key cylinder 10 of the rear tube 2 on one side, and the pipe 13 is welded. Then, the operation cable 12 is inserted into the pipe 13 and wired. A rear wheel mudguard 14 is arranged below the left and right rear tubes 2.

By inserting a key into the key hole 11 and rotating it, the seat lock 8 is unlocked via the operation cable 12. The lower portion of the operation cable 12 is inserted into the pipe 13, and even if a hand is inserted from the lower side of the tail cover 3, the pipe 13 is an obstacle and the operation cable 12 cannot be bent and pulled, so that it is stolen. Can be prevented.

[0011]

As described above, since the present invention is configured as described above, even if the operator tries to bend and pull the operation cable 12 by inserting his / her hand from the lower side of the tail cover 3,
Since the pipe 13 is an obstacle, the operation cable 12 can be prevented from being stolen in addition to being operated by a key.
Then, the guard plate of the operation cable 12 becomes unnecessary, and the operation cable 12 can be wired in a short length through the pipe 13. The position of the key cylinder 10 can also be arranged inside, so that the cost can be reduced and the appearance can be improved.
