Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scooter in which a storage box is arranged below a seat, and more particularly to a structure of the storage box.

[0002]

2. Description of the Related Art Conventionally, there is a scooter in which a storage box is arranged below a seat. Many of the storage boxes are configured to be opened upward and opened and closed by a sheet. The seat has a structure in which the front part is mainly supported by a storage box via a hinge, and the rear part is configured to be vertically rotatable, and the rear part is locked by a locking device provided at the rear part of the storage box. Was becoming. The hinge is configured such that a support shaft extending in the vehicle width direction is pivotally supported by a seat front portion and a hinge bracket projecting forward from the front end portion of the storage box. Further, most of the load of this type of seat is received by the front part and the rear part of the storage box.

Since the legs of the scooter are extended forward when the occupant is seated, the front end of the seat is formed narrow so that the riding posture is not impaired.
That is, the hinge is arranged at the front end of the narrow seat. On the other hand, in this type of storage box, the opening edge of the upper opening is close to the outer side of the seat in order to increase the opening area and maximize the capacity.

[0004]

However, even in the storage box having a large opening area and a large capacity as described above, there has been a demand to further increase the capacity.

In order to further increase the capacity of this type of storage box, the sheet width may be expanded. However, simply widening the seat width causes problems in supporting the front portion of the seat, as will be described below. As described above, most of the load of the scooter seat is received by the front part and the rear part of the storage box. Therefore, when the seat width is made wider, the seat should be inclined to the left and right. Tatsuki easily occurs. This rattling of the sheet makes the seal of the upper opening of the storage box uncertain.

In order to prevent the rattling of the seat, the support width of the portion supporting the front portion and the rear portion of the seat may be widened. However, the hinge supporting the front portion of the seat has a great influence on the width dimension at the frontmost portion of the seat. Therefore, it cannot be formed to be wide. This is because if the hinge is formed wide, it is difficult for the occupant to extend his / her legs forward when seated on the seat.
This is because the riding posture is impaired. That is, although the rear part of the storage box supporting the rear part of the seat can be formed wide, the front end part of the storage box supporting the front part of the seat through the hinge cannot be formed wide, so that the seat can be made wider. If it is formed into a square shape, rattling at the front portion cannot be completely prevented.

When the opening width of the storage box is expanded, the plane shape of the front portion of the opening has a large radius of curvature.
If the hinge bracket is provided so as to project from the front end portion of the storage box, the portion of the storage box front portion that serves as the base of the hinge bracket will be constricted. That is, when the load on the front portion of the seat is received by the hinge bracket, stress tends to concentrate on the constricted portion.

The present invention has been made to solve the above problems, and an object of the present invention is to increase the capacity of a storage box so that the seat can be reliably supported even if the opening width is widened. Moreover, the riding posture should not be impaired.

[0009]

SUMMARY OF THE INVENTION A storage device for a scooter according to the present invention includes a hinge bracket which is located at a central portion in the vehicle width direction and extends forward from an opening of a storage box to support a hinge, and the hinge bracket. And a plate-shaped load receiver that connects both sides in the vehicle width direction and the opening edge of the storage box and supports the leg portion of the seat integrally projectingly at the front portion of the storage box.

[0010]

Since the load of the seat front portion is applied to the load receiver located rearward of the hinge axis, the support width of the portion supporting the seat front portion becomes wide without expanding the width of the hinge and the seat front end portion. Moreover, the load on the front portion of the seat is easily applied to a wide area of the front portion of the storage box via the load receiver and the bracket for hinges and is easily dispersed.
