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 using a rear fender of a front and rear separation type, and more particularly to a seat lock device suitable for a tandem seat.

[0002]

2. Description of the Related Art A motorcycle seat is removably attached to a seat rail by a seat lock device. A front end is engaged with a rear end of a fuel tank, and a rear end is attached by a seat lock. Some have become. Some long ones such as tandem seats have an additional structure for engaging the seat rail to stabilize the middle part.

[0003]

In the case of using a separated type in which the rear fenders are separated from each other in the front and rear directions, there is no rear fender at a middle portion in the front-rear direction of the seat. If this is the case, it becomes easier for the hands to enter the seat lock portion from the outside, and there is a risk of theft due to an unintended unlocking operation.

For this reason, when a rear fender of this type is employed, the seat lock position is limited to the rear end side of the seat. However, the mounting rigidity of the seat is low, so that the engagement structure of the intermediate portion is required. Is required.

[0005] In this case, however, the seat must be disengaged by sliding the seat back and forth when attaching and detaching the seat.
Since a certain kind of knack is required, it is desired that a seat lock can be employed instead of the engagement structure of the intermediate portion so as to facilitate the attaching / detaching operation. In particular, such demands are stronger in tandem seats.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a seat lock device which can be locked at an intermediate portion of a seat and has a structure in which a user cannot easily access a seat lock portion from outside.

[0007]

According to a first aspect of the present invention, there is provided a motorcycle seat lock device which is supported by a pair of left and right seat rails and is detachably mounted by a seat lock. A motorcycle having a rear fender and a pair of rear fenders arranged separately in the front-rear direction above the rear wheel, and corresponds to an intermediate portion between the front and rear portions of the rear fender and an intermediate portion in the front-rear direction of the seat. A seat lock is provided at a position sandwiched between the left and right seat rails, and a lower portion of the seat lock is covered with a cross member extending between the left and right seat rails. A rib extending to the cross member side through the rib, a closed space surrounding the seat lock is formed by the rib, the bottom plate and the cross member. Seat lock device of an automatic two-wheeled vehicle that.

A second invention is characterized in that, in the first invention, the sheet is a tandem sheet.

According to a third aspect of the present invention, in the first aspect, at least a part of a front portion of the rear fender is used as an exterior member, and a key operation portion for unlocking a seat lock by a key is provided on a side surface thereof. Features.

[0010]

According to the first aspect of the invention, the seat can be locked at the intermediate portion of the seat, so that the mounting rigidity of the seat can be increased, and the conventional engagement structure can be eliminated, so that the attaching and detaching operation is easy and quick. become.

In addition, a separate rear fender is adopted,
Even though the seat lock is located in the middle part where the rear fender is not provided, the seat lock is housed in the closed space, so that it is difficult to access from the outside, which helps to prevent theft.

Moreover, since the lower part of the seat lock is covered with the cross member, even if muddy water or the like is directly jumped up to the bottom plate of the seat, the muddy water or the like can be prevented from adhering to the seat lock.

According to the second aspect of the present invention, since the tandem seat is employed, the seat lock device is suitable for a tandem seat which has a long seat length and a particularly high demand for mounting rigidity.

According to the third aspect of the present invention, at least a part of the front portion of the rear fender is exposed, so that it is not necessary to cover the rear fender with a side cowl or the like as in the prior art, and the side cowl can be omitted or reduced in size. In addition, a key operation unit of the seat lock can be provided by utilizing the appearance unit. In addition, it can be multifunctional as an article storage unit such as a battery.

It is designed to be attached to.

As is apparent from FIG. 1, the rear fender is configured as a separate type fender which is separated into a rear fender front portion 16 and a rear fender rear portion 17 and is disposed at an interval in the front and rear directions.
Supported by

As is apparent from FIG. 11, the front portion 16 of the rear fender also serves as a battery box, and a battery 71 is housed in a housing portion 70 formed as a recess for that purpose. However, other electrical components such as a fuse and an ignition unit and other articles are also appropriately accommodated at the same time.

The rear fender front part 16 is formed by engaging a hook part 72 formed on the bottom part on the front part side with the first cross pipe 21 from above, and fastening the rear part to the side surface of the sub pipe 20 with a bolt 73. It is attached to the sub pipe 20.

The lower portion of the front portion 16 of the rear fender protrudes downward from the front extension 30a (FIG. 1) of the bottom plate 30 of the seat to form an external portion, and a key for unlocking the seat lock 27 is provided on a side surface thereof. An operation unit 74 is provided.

When a key (not shown) is inserted into the key operation portion 74 and rotated, an operation wire 75 having one end connected thereto and passing over the seat rail 8 and the other end attached to the seat lock 27 is connected. It is designed to be unlocked.

As is apparent from FIG. 13, the rear fender rear portion 17 is provided with the engaging portion 80 at the front end and the extension portion 28 of the hook portion 28.
a, which is attached to the seat rail 8 by being bolted to a stay 29 extending from the rear end of the seat rail 8 at the rear side surface. The other extension 28b is also engaged from above with a recess formed at the upper end of the front part on the rear side wall of the rear fender.

A space 84 between the cross pipes 25 is for storing documents.

Next, the operation of this embodiment will be described. As is clear from FIGS. 1 and 12, the intermediate portion of the seat 13 can be locked by the seat lock 27, so that the mounting rigidity of the seat 13 can be increased, and the conventional engagement structure can be eliminated, so that the attaching / detaching operation can be performed. Become easy and quick.

In addition, the separate rear fenders (16, 1
Since the seat lock 27 is housed in the closed space 39 despite the fact that the seat lock 27 is located at the intermediate portion where the rear fender is not provided, it is difficult for the outside to be accessed by the user, which helps to prevent theft.

Further, since the lower portion of the seat lock 27 is covered with the cross plate 23, even if muddy water or the like is directly jumped up to the bottom plate 30 of the seat 13, most of the muddy water can be blocked off by the cross plate 23, and the ribs 37 and 38 furthermore, Further, since it is possible to reliably shut off, adhesion of muddy water or the like to the seat lock 27 can be effectively prevented.

The seat 13 is a tandem seat that is particularly required to increase the mounting rigidity due to a long seat length. However, the seat lock device satisfies the above-mentioned requirement, and thus the tandem seat can be used. It becomes suitable.

Furthermore, since the lower part, which is at least a part of the front part 16 of the rear fender, is exposed and becomes an external part, it is not necessary to cover the entire part with a side cowl or the like as in the prior art. The key operation unit 74 of the seat lock 27 can be provided by making it possible to reduce the size and utilizing the external part. In addition, the battery 7
It can be multifunctional as an article storage unit such as the first.

The present invention is not limited to the above-described embodiment, but can be variously modified. For example, the present invention is not limited to the cross plate 23 but may be a cross pipe as long as a sufficient shielding area can be secured. Further, the entire front portion 16 of the rear fender may be an exterior member.
