Abstract

PROBLEM TO BE SOLVED: To contain a pillion step and to facilitate containing it for a rider sitting thereon. SOLUTION: A boss 42 is mounted on a stop of a step frame 41 mounted on a body frame and the pillion step 17 is mounted thereon freely of rotating via a rotation center shaft 60 inclining upward in front. The pillion step 17 is a plate type member having a width allowing approximate center of a foot to be put thereon for facilitating the rider's planting it firmly. The contained pillion step 17 overlaps with a rear end extending part 70 formed on a rear end of a floor panel 12 while a rear end extending part 12a has approximately the same shape as the pillion step 17 and extends inside of an extended lower part 63 via a stepping part 61. An opening 62 adapted for protruding the boss 42 is formed backward on the stepping part 61.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a pillion step, which is a step for a passenger provided in a two-seater motorcycle.

[0002]

2. Description of the Related Art Japanese Patent Publication No. Hei 4-90815 discloses a motorcycle in which a pillion step, which is plate-shaped and has a size on which the entire foot can be put, is fixed substantially horizontally to a side of a vehicle body below a front seat of a seat. It is shown. The plate-like step has the advantage that the foot can be easily placed on the bar and the degree of freedom is high. Also known is a pillion step that is freely foldable about a rotation center axis extending in the vehicle longitudinal direction.

[0003]

The pillion step is rotatable so that it can be stored when there is no passenger, but when the pillion step is stored, the pillion step can be rotated while the front rider is seated. It is desirable to be able to do so. However, even if it is rotatable, if the center axis of rotation is horizontal as in the above-described conventional example, it is difficult to store the pillion step while the rider is seated. Further, on the passenger side, it is difficult to step on when the pillion step is plate-shaped and its surface is horizontal at the time of deceleration or the like. Then, this invention aims at solving such a problem.

[0004]

In order to solve the above-mentioned problems, a pillion step structure according to the present invention is provided in a plate-shaped pillion step rotatably provided on a side of a vehicle body between a stored state and a used state. The rotation center axis of the pillion step is inclined forward and upward with respect to the horizontal plane.

Further, the step floor can be extended to a position facing the pillion step at the time of storage. In this case, the rotation center axis may be provided on a boss extending from the vehicle body frame, and an opening protruding outward from the boss may be provided on the step floor, and the opening may be opened rearward of the vehicle body. . Further, the shape of the portion facing the pillion step in the extension of the step floor may be substantially the same as the shape of the pillion step in storage.

[0006]

According to the pillion step of the present invention, the step is a plate-shaped retractable type, and while being able to increase the degree of freedom in putting on the passenger, the pillion step is rotatable with respect to an axis inclined upward and forward. Therefore, when the passenger intends to store the pillion step without a passenger, the rider can easily store the pillion step by finishing the passenger step from the front with his feet while sitting in the front seat, thereby improving operability.

In addition, since the rotation center axis is inclined forward and upward, when the passenger applies a force to the foot during deceleration or the like, the support surface of the pillion step with respect to the foot can be made almost at a right angle. .

In addition, since the step floor is extended to a position facing the pillion step at the time of storage, the storage state can be made to have an appearance that is integrated with the step floor, and the appearance is improved. In addition, if the portion of the step floor facing the pillion steps during storage is substantially the same shape as the pillion steps, the sense of unity during storage can be further enhanced and the appearance can be further improved.

Further, an opening is provided at the rear end of the step floor for projecting a boss for attaching a pillion step, and this opening is opened to the rear of the vehicle body. Therefore, when the step floor is mounted on the vehicle body, only the boss is used. Can be easily attached while the other frame portion is covered inside, so that workability is good and appearance is good.

Next, the pillion step will be described. FIG. 11 is a perspective view showing the mounting portion of the pillion step 17 in a housed state, and FIG. 12 is a schematic plan view showing the usage state of the pillion step 17. As is evident in FIG.
The pillion step 17 is rotatably supported by a rotation center shaft 60 with respect to a boss 42 provided on the top of the step frame 41, and is used in a position where it is tilted outward substantially horizontally and in a stowed storage position. And it is rotatable. The rotation center shaft 60 has a forward-inclined inclination, and is easily housed by the rider pushing up with his feet backward while sitting in the front seat 14a.

The pillion step 17 during storage faces the rear end extension 12a of the step floor 12. The rear end extension portion 12a is located at a position which is retracted one step lower toward the inside of the vehicle body so that the pillion step 17 at the time of storage overlaps, and is substantially the same as the pillion step 17 (substantially triangular).
Is formed.

The trailing end extension 12a is a pillion step 17
Is specially extended to a position (FIG. 3) where the rear portion of the step floor 12 overlaps the side of the swing unit 20 in order to accommodate the boss 42. The step portion 61 has an opening 62 for projecting the boss 42. The opening 62 is open to the rear of the vehicle body (see FIG. 2). Below the opening 62, an extended lower portion 63 is provided, which protrudes outward one step higher than the rear end extending portion 12 a, and covers the top side of the step frame 41.

FIG. 12 shows a plan view of the pillion step 17 in the use state. The front-rear width W of the pillion step 17 is smaller than the length of the passenger's foot F, so that only the center portion thereof can be placed. ing.

Next, the operation of this embodiment will be described. The pillion step 17 is a plate-shaped but retractable type, and is rotatable about an axis 60 inclined upward and forward. Therefore, when the pillion step is to be stored without a passenger, the The operability is improved because the pillion step 17 can be easily stored rearward and obliquely upward from the front with the foot while sitting on the front seat 14a.

In addition, since the rotation center shaft 60 is inclined forward and upward, when the force is applied to the foot F at the time of deceleration or the like, the support surface of the pillion step 17 with respect to the foot can be almost at a right angle. Become. In addition, since the front-rear width W of the pillion step 17 is made smaller than the length of the passenger's foot F so that only the center part of the foot F can be placed, the angle of contact of the foot with the pillion step 17 can be freely adjusted. .

Further, a part of the floor panel 12 is extended to a position facing the pillion step 17 at the time of storage to form the rear end extension 12a of the floor panel. 12a can be made to have an appearance with a sense of unity, and the appearance is improved. In addition, if the portion facing the pillion step 17 of the rear end extension 12a of the floor panel at the time of storage is substantially the same shape as the pillion step 17,
Further, the sense of unity at the time of storage can be strengthened to further improve the appearance.

Further, the rear end of the floor panel 12 is provided with an opening 62 from which the boss 42 for attaching the pillion step 17 projects, and the opening 62 is opened to the rear of the vehicle body. At the time of mounting, only the boss portion 42 is exposed outside, and the other step frames 41 and the like can be easily mounted in a state of being covered inside, so that workability is good and appearance is good.
