Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is applied to a small vehicle equipped with three or more wheels, and is arranged below a pair of left and right fenders that cover at least the upper part of a pair of left and right wheels. This invention relates to a luggage box device.

(Prior Art) Conventionally, there have been three or four-wheeled vehicles for traveling on rough terrain that have a straddle-type seat disposed diagonally above and behind an engine mounted near the center of the vehicle body. In this type of vehicle, fenders that cover at least the upper portions of the left and right wheels are often integrally formed on the left and right wheels.

When such a vehicle is provided with a luggage box for storing small items, a downwardly recessed recess is formed in the pair of left and right fenders, and the opening of this recess is closed with a driver's seat or a lid plate to provide waterproofness. However, when closing the opening with a driver's seat, there was a problem in that a large seat had to be attached and detached when taking out and putting in small items, resulting in poor workability. In addition, if you close the opening with a lid plate, the waterproofness is likely to be uncertain when driving in the rain, and if another cargo platform is installed above the fender, it will be difficult to open and close the lid plate. There were also some inconveniences.

(Object of the Invention) The present invention has been made in view of the above circumstances, and it is not necessary to attach and detach a large driver's seat to open and close the luggage box, improving workability, and
To provide a luggage box device for a small vehicle, which has better waterproofness than the case where the opening of the luggage box is closed with a lid plate, and also allows the luggage box to be opened and closed even when another loading platform is installed above the fender. The purpose is to

(Structure of the Invention) The present invention achieves the above object by movably arranging a luggage box below the left and right fenders. That is, at least three wheels, an engine mounted near the center of the vehicle body, a straddle-type driver's seat mounted diagonally above and behind the engine, and integrated left and right fenders that cover at least above the pair of left and right wheels. A small vehicle is provided with a luggage box located between the pair of left and right wheels and below the fender, and the luggage box has a first position where the opening thereof is closed by contacting the lower surface of the fender. , and a second position where the opening is opened by being deviated from the fender in the front-rear direction.

50 is a luggage box made of synthetic resin. The luggage box 50 is made slightly narrower than the left and right seat rails 18 and the bag tube 20 (FIG. 5). The left and right sides of the baggage box 50 are provided with brackets 52 fixed to the bag tube 20,
It is rotatably connected to 52a and 52b by pins 54, 54a and 54b. An opening 50a is formed in the luggage box 50, and a sealing member 56 made of an elastic material is fitted around the periphery of the opening 50a. In the first position shown by solid lines in FIG. 2, the sealing member 56 abuts against the lower surface of the rear fender 38, closing the opening 50a. In FIG. 2, reference numeral 58 indicates a stopper that spans the left and right bag tubes 20.
The baggage box 50 is stabilized by abutting at the position. When the luggage box 50 is rotated clockwise in FIG. 2 to the second position shown by the imaginary line, the opening 50a is deviated rearward from the rear fender 38 and opens rearward. 60 is a tail light, which is fixed to the luggage box 50.

On the lower surface of the rear fender 38, there are partition walls 62, 62 extending between the luggage box 50 and the seat rail 18.
a and 62b are integrally molded (Fig. 5). The rear fender 38 is fixed to the seat rail 18 by this partition wall 62. Also, this partition wall 62
has the effect of preventing mud and water kicked up by the rear wheels 26 from entering the opposing portion of the luggage box 50 and the rear fender 38, further improving the waterproofness of the luggage box 50. It is preferable to fix the luggage box 50 at the first position and install a suitable locking mechanism so that the seal member 56 can be pressed against the lower surface of the rear fender 38 with an appropriate pressure. Further, in FIG. 5, 64 is an exhaust muffler.

According to this embodiment, when the luggage box 50 is rotated clockwise in FIG. 2 to the second position, the opening 5
Loading and unloading is possible from 0a, and when it is rotated counterclockwise to the first position, the sealing member 56 is pressed against the lower surface of the rear fender 38, so that the opening 50a
is closed watertight. Therefore, opening and closing operations of the luggage box are significantly easier than in the conventional case where the driver's seat and lid plate are attached and detached. Further, since the opening 50a is located on the lower surface of the rear fender 38, rain will not enter the luggage box 50 even if the baggage box 50 is left in the rain, and since the sealing member 56 is pressed against the rear fender 38, fire protection is also good. Furthermore, by creating deep luggage boxes between the seat rails, you can easily secure a large amount of luggage space.

FIG. 6 is a sectional view of a main part of another embodiment. In this embodiment, a tail light 60A is attached to a cross pipe 44A that connects the rear ends of the left and right seat rails 18, and this tail light 60A extends not only rearward but also downwardly. I tried to illuminate it. Therefore, by rotating the luggage box 50 around the pin 54 and opening the opening 50a, the tail light 60 can be opened.
The downward light A illuminates the inside of the luggage box 50. This makes it easier to take things in and out at night.

In the embodiments described above, the present invention is applied to the rear fender 38 of a four-wheel vehicle, but the present invention also includes an application to the front fender 36 of a four-wheel vehicle. Further, the luggage box 50 may be moved not only by rotating as in this embodiment but also by other moving means such as sliding on a slide rail.

(Effects of the Invention) As described above, the present invention provides a luggage box under the left and right fenders, and a first position where the opening of the luggage box is closed by contacting the lower surface of the fender, and a first position where the opening is closed from the fender. Since it can be moved back and forth between the opening and the second position, there is no need to attach or detach a large driver's seat to open or close the luggage box.
Good workability. Additionally, the opening is located under the fender, making it highly waterproof and prevents rainwater from entering. Furthermore, even if another cargo platform is mounted on the fender, there is no problem in opening and closing the cargo box.
