Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a scooter-type vehicle equipped with a storage box for storing a helmet below the seat.

[Conventional technology]

BACKGROUND ART In recent years, scooter-type vehicles such as motorcycles and tricycles equipped with body covers are required to accommodate helmets. An example of a scooter that meets this demand is disclosed in Japanese Utility Model Application Publication No. 61-201988. This has a storage box located below the seat that can be opened and closed by the seat, and the storage box is formed to store the helmet with its top facing up.

[Problem that the invention seeks to solve]

However, in such a structure, the helmet is stored directly under the seat, and the seat bottom plate needs to be higher than the top of the helmet, resulting in a higher seating surface. Additionally, there was a fear that the occupants would be forced to take an ergonomically impossible posture when placing their feet on the road surface. Therefore, in order to solve this problem, it may be possible to make the seat thinner, but doing so would cause the inconvenience of worsening the ride comfort.

[Means for solving problems]

The present invention has been made in view of these circumstances, and it is an object of the present invention to provide a scooter type vehicle that can lower the seating surface without impairing riding comfort.

The scooter type vehicle according to the present invention is provided with a support part for supporting the top of the helmet at the bottom of the storage box, and a protrusion that protrudes downward from the bottom plate of the seat and faces the opening of the helmet stored with the opening facing upward. It has a section.

[Effect]

In the present invention, the bottom plate of the seat can be lowered using the opening formed in the helmet.

Movement of the helmet 41 is restricted. An inclined surface 32b is provided on the front side of the bottom located in front of the support part 32a, in other words, between the left and right support legs 33, 33, and slopes upward along the inner surface of the support part 32a. On the other hand, both sides of the support portion 32a are formed into a flat plate shape that is slightly curved backwards, and a battery 42 is mounted horizontally on the left side of this flat plate portion, that is, at a position that is tilted toward the vehicle width direction from the center of the vehicle body. An opening 43 having a rectangular shape larger than its cross section is provided. Reference numeral 44 denotes a lid body for opening and closing this opening 43, and is attached by engaging engagement pieces 44a protruding from the front and rear parts with the peripheral edge of the opening 43, and releasing the engagement of the retention pieces 44a. removed by. Reference numeral 45 denotes a pantry box that supports the buffet box 42, and is formed integrally with the storage box 32 below the opening 43 from a fiber-reinforced resin material. Note that there is a bracket 46 on the front side of the upper opening of the storage box 32 to which the front end of the seat 3 is pivotally attached, and a bracket 46 on the rear side that pivotally attaches the front end of the seat 3.
A seat support portion 47 for supporting the rear portion of the seat lock 48 and a mounting portion 49 for the seat lock 48 are integrally formed.

The seat 3 includes a bottom plate 51 whose front end is pivoted to the bracket 46 of the storage box 32, and a cushioning material 52 such as sponge provided on the bottom plate 51. The bottom plate 51 is integrally formed with a peripheral wall so as to cover the upper opening of the storage box 32, and has a protrusion in the center that protrudes downward and faces the opening of the helmet 41, which is stored upside down with the opening facing upward. A portion 51a is integrally provided. Projection part 5
1a is formed in the shape of a truncated cone whose diameter gradually decreases as it goes downward, and holds the helmet 41 by having its outer circumferential surface contact the inner circumferential edge of a band provided on the circumferential edge of the helmet 1-41.

Reference numeral 53 denotes a support leg integrally protruding from the rear part of the bottom plate 51, which abuts against the seat support portion 47 of the storage box 32 and supports the seat 3.
support.

A sealing material 54 is pressed against the peripheral wall of the bottom plate 51 of the seat 3 in the closed state to prevent rain and the like from entering the storage box 32. The sealing material 54 is formed into a band shape from an elastic material such as elastic rubber or rubber-covered sponge rubber, and is attached so as to cover the periphery of the opening of the storage box 32. The range is the area excluding the front end and rear end of the storage box 32, as shown by the two-dot chain line in FIG.

56 is a synthetic resin fuel tank disposed behind the storage box 32. This fuel tank 56 has a large capacity (
and the left and right sides of the car body.

The right side of the bottom to adjust the weight distribution! It extends below the storage hook 32. Further, the oil supply part is arranged at the front part, and a recessed part 5 provided at the rear part of the bottom plate of the seat 3.
It is facing within 1b.

61 is an oil tank made of synthetic resin that stores lubricating oil to be supplied to the engine body 11. This oil tank 61
is arranged in a space formed between the unit swing type engine 7 and the storage box 32 and in front of the rear wheel 8, and the left side part extends to the front of the pantel box 37 to increase the volume. It's being served. The oil supply portion of the oil tank 61 is disposed on the front upper surface thereof and is covered with a cap 62 so as to face the lower side of the inclined surface 32b provided on the bottom front side of the storage box 32. And this cap 6
2, the inclined surface 32b is provided with a refueling opening 64 that is opened and closed by a lid 63. This lid 63 is also detachable from the opening 64 by providing a retaining piece 63a like the lid 36 described above. Reference numeral 65 designates an exhaust muffler disposed on the right side of the vehicle body, to which an exhaust pipe 66 extending downward from the cylinder 11a and extending rearward from the lower side of the crankcase Ilb is connected.

In the scooter configured in this manner, by opening the seat 3 and inserting the helmet 41 into the storage box 32 with the top portion facing down, the top portion is supported by the support portion 32a. Therefore, the helmet 41 is positioned and stored in the center of the storage box 32 with the opening facing upward. When the seat 3 is closed, the bottom plate 5
The protruding portion 51a of 1 faces the opening of the helmet 41,
It comes into contact with the pad and holds it. here,
By facing the opening of the helmet 41, the protrusion 51a can lower the bottom plate 51 downward. As a result, the seating position can be lowered by the amount lowered, and the thickness of the cushioning material 52 can be ensured.

In the above embodiment, an example was described in which the outer circumferential surface of the protrusion 51a was brought into contact with the pad of the helmet 41, but the present invention is not limited to this and does not necessarily need to be brought into contact.

〔Effect of the invention〕

As explained above, according to the present invention, a support part for supporting the top of the helmet is provided at the bottom of the storage box, and the support part protrudes downward from the bottom plate of the seat and faces the helmet opening of the stored helmet with the opening facing upward. Since the protrusion is provided, the bottom plate of the seat can be lowered using the opening of the helmet stored directly under the seat.

Therefore, the seating surface can be lowered by the amount that the bottom plate of the seat has been lowered, and the thickness of the cushioning material can be ensured, so the riding comfort will not be affected (
The seating surface can be lowered to allow your feet to touch the road (preventing you from being forced into an awkward position).
