Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a motorcycle having a footrest floor having a flat upper surface between a steering handle and a driver's seat.

In conventional scooter-type motorcycles of this type, the upper part of the rear wheel is covered with a large container-shaped rear cover, so the rear end of the footrest floor can only be extended to just below the front edge of the driver's seat. . For this reason, even when the driver wanted to pull his/her feet back, his/her feet would hit the lower front surface of the rear cover, and the driver would not be able to pull his/her feet back sufficiently, resulting in a problem with foot placement. In addition, if the body width is narrowed to create a skater-type motorcycle suitable for short-distance movement within the city, the width of the footrest floor, which has a flat top surface, must also be narrowed. A problem arises in that the area of the floor becomes smaller and the footrest becomes worse.

The present invention has been made in view of the above circumstances, and provides a motorcycle that allows the driver to pull his or her feet sufficiently far back and secures good footrest even if the width of the footrest floor is narrow. The purpose is to provide.

In order to achieve this objective, the present invention extends the rear part of the floor to above the rear wheels, and the seat pillar part that supports the driver's seat is raised from the rear end of the floor, thereby creating a footrest space below the driver's seat. It was formed. The present invention will be explained in detail below based on the illustrated embodiments.

Fig. 1 is a side view of one embodiment of the present invention, Fig. 2 is a plan view, Fig. 3 is a sectional view taken along the line 4, 5
The figures are a front view and a rear view. Code 1 in Figures 1 to 3
0 is a body, which includes a footrest floor 12, a fixed front fender 14, and a seat pillar portion 16. The upper surface of the footrest floor 12 near the center is formed into a substantially flat plate shape. A front portion 12a of the floor 12 continuously rises obliquely toward the front and is connected to a substantially horizontal fixed front fender 14. A rear part 12b of the floor 12 continuously stands up diagonally toward the rear, and a seat pillar part 16 stands up diagonally forward from the rear end. Two pipe frames 18 (18a, 18b, see FIG. 3) are passed through the inside of the body 10, and the floor 12 is placed on these pipe frames 18, and the left and right side edges are bent downward. The cross section is approximately trapezoidal with an open bottom.

An engine unit 20 and an exhaust muffler 22 are housed below the central portion of the floor 12, and the lower portions of these are covered with an undercover 24. The engine unit 20 incorporates a forced air cooling fan, a centrifugal clutch, a planetary gear reducer, and the like.

A rear wheel 26 is located below the rear portion 12b of the floor 12, and its front end is held by a swing arm 28 supported by a pivot shaft (not shown). 30 is a shock absorber that supports this rear wheel 26. The output shaft of the engine unit 20 is transmitted via a universal joint to a drive shaft (not shown) inserted into a swing arm 28, and its rotation is further transmitted to a rear wheel 26. Front part 12a of floor 12
A carburetor 32 and an intake air purifier 34 are arranged below.

A driver's seat 36 is provided at the upper end of the seat pillar section 16.
is attached so that it protrudes forward. This seat 36 can be rotated by operating a lock 38, and a fuel tank 40 housed in the pillar section 16 can be rotated.
A lubrication port appears below the seat 36. Note that the body 10 is made narrow so that its width is approximately the same as that of the driver's seat 36.

A steering shaft cylinder 42 is fixed to the front end of the pipe frame 18, a steering front wheel 46 is held at the lower end of a steering shaft 44 inserted through the steering shaft cylinder 42, and a steering handle 48 is held at the upper end of the steering shaft 44. is fixed. The steering shaft cylinder 42 and the steering shaft 44 are covered by a narrow handle column 50.

The driver sits on the driver's seat 36 and places both feet on the upper surface of the floor 12. In this case, both feet may be placed near the center of the floor 12 with the left and right sides aligned, but since the rear part 12b of the floor 12 extends above the rear wheels 26, the space A between this rear part 12b and the driver's seat 36 is As shown in FIG. 1, both feet may be placed on the floor 12 by shifting them back and forth so that one foot is positioned in the footrest space A. In this case, it becomes easier to shift your weight back and forth. A foot print B shown by a phantom line in FIG. 2 indicates the position of the foot at this time.

In this embodiment, the front part 12a is tilted upward toward the front, so it is easy to shift the weight forward, and if the front wheel load is increased when starting, etc., even if the front and rear wheel spacing (wheelbase) is small, it will be sufficient. Maneuvering stability performance can be obtained.

In addition, the seat pillar section 16 is tilted forward as shown in Fig. 1 to position the driver's seat 36 as far forward as possible, so the center of gravity can be positioned sufficiently forward without increasing the distance between the front and rear wheels (wheelbase). This makes it possible to reduce the size of the vehicle and improve running stability at the same time. Furthermore, in this embodiment, floor 12
The rear part 12b of the vehicle doubles as a fender for the rear wheels, simplifying the structure, and since the seat 36 protrudes significantly forward, there is a large footrest space A below the seat 36, which can also be used as a luggage space. Become. Reference numeral 51 shown by imaginary lines in FIG. 1 shows an example of the arrangement of luggage baskets.

If removable shield plates 52, 52a, and 52b shown in phantom lines are attached to the handle column 50, the width of the handle column 50 will be substantially increased and the windshield effect will be increased. Furthermore, as shown in FIG. 3, a folding type auxiliary plate 54,
If 54a and 54b are provided and are spread out and fixed at the imaginary line position by an appropriate locking mechanism, the substantial width of the floor 12 is expanded and the footrest is further improved.

As described above, the present invention extends the rear part of the floor to above the rear wheels and forms a footrest space between the driver's seat and the rear part of the floor, so the length of the floor in the front and back direction can be ensured long and the footrest is extended to above the rear wheels. It can be pulled far back to the bottom of the seat. Furthermore, even if the floor width is narrow, good foot placement can be ensured by shifting both feet back and forth.
