Abstract

PURPOSE:To enable a vehicle to be driven in a comfortable attitude further improving running stability of the vehicle facilitated in its on-off getting by forming a scooter structure providing a floor on a car body frame in the front from a horizontal unit engine and providing in its upper position a seat and behind it a seat back tilting and rising diagonally in the rear. CONSTITUTION:A bracket 4 is secured to a low position in the rear part of a front part frame 1a in a car body frame 1, and a horizontal unit engine 5 is connected in its front end to this bracket 4 by a pivot shaft 6 and swingably supported in a vertical direction. A seat 9 is set up in an upper part of a boundary position between the front part frame 1a and a rear part frame 1b, having a seat back 9b tilting and rising diagonally in the rear behind a seating part 9a, and a head rest 10 is provided in the upper end. A stepthrough type floor 11 is provided on the front part frame 1a. The rear part frame 1b arranges an engine accessory equipment of fuel tank 13, battery 14, oil tank 15, etc. Thus a car body, lowering its center of gravity containing an engine 5a, enables the running stability to be improved further the on-off getting to be facilitated.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a scooter type vehicle.

(Prior Art) A scooter-type vehicle is operated by sitting on a seat and placing one's feet on the floor.

Therefore, while driving, the driver must maintain his/her own posture, which causes severe fatigue after driving for a long time.

Therefore, for example, as in the motorcycle shown in Japanese Patent Application Laid-Open No. 60-60084, only the seat part of the body frame is recessed, and the seat is installed here to form a slight backrest. In addition, a backrest that can be raised and lowered so that the back rests against the rear of the seat is provided, and when this backrest is raised and fixed, it supports the driver from the waist to the back, allowing him to drive in a comfortable posture. has been done.

(Problem to be solved by the invention) However, according to the above structure, the front side of the seat is inevitably high and there is no step-through, making it difficult to get on and off, especially for female drivers wearing Scar I. In addition to being unable to drive, the position of the foot rest is fixed, so if the driver's legs are short, the driver's feet will not be able to reach the foot rest, and if the driver's legs are long, the driver's knees will be in a high position while driving. Posture becomes unnatural. Therefore, as shown in this bulletin, it is necessary to be able to adjust the distance between the seat and the footrest to suit the physique of the driver, which inevitably complicates the vehicle body structure. It is.

An object of the present invention is to provide a scooter type vehicle that can be driven in a comfortable posture without complicating the vehicle body structure, has good running stability, and is easy to get on and off.

[Structure of the invention]

(Means for Solving the Problems) In order to solve the problems addressed by the above-mentioned prior art, this invention provides the following:
The front end of the horizontal unit engine is connected to the lower part of the vehicle body frame so that it can swing freely in the vertical direction, and a floor is provided on the vehicle body frame in front of the engine to form a scooter structure, which is installed above the horizontal unit engine. A backrest that stands up and tilts diagonally backward is provided at the rear of the seat, and engine accessories such as a fuel tank, battery, and oil tank are arranged on the body frame behind this backrest.

(Function) With the above configuration, when you sit on the seat, you can lean against the backrest, allowing you to drive in a comfortable posture.

At this time, the driver's legs can be freely stretched forward as the front of the seat is on the floor, allowing the driver to place his or her feet in the optimal position regardless of their length.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a vehicle body frame 1 used for a scooter type vehicle includes an underbone type front frame 1a formed in a substantially U-shape when viewed from the side, and this frame 1a.
A rear frame 1 is connected to the rear part of the
A head vibrator 3 for supporting the front wheel 2 is fixed to the front part of the front frame 1a.

A bracket 4 is fixed to a low position at the rear of the front frame 1a of the vehicle body frame 1 by welding or the like.
The front end of a horizontal unit engine 5 of a substantially horizontal cylinder unit swing type is connected by a pivot shaft 6 and supported so as to be swingable in the vertical direction. The rear part of this horizontal unit engine 5 is the rear frame 1bk:! 1
11 unit 7, and a rear shaft 8 is pivotally supported by the rear end of the unit case 5b of this horizontal unit engine 5, and is rotated by the drive of the engine 5a.

A seat 9 on which the user can rest deeply is installed above the boundary between the front frame 1a and the rear frame 1b. This seat 9 has a backrest 9b that stands up obliquely rearward at the rear of a seat part 9a, and a headrest 10 is provided at the upper end of this backrest 9b.

A step-through type floor 11 is provided on the front frame 1a in front of the seat 9, so that a driver 12 sitting on the seat 9 can extend his legs 12a forward and place his legs 12b/j2f in any desired position. It has become.

On the rear frame 1b located above the rear wheel 8, engine ancillary equipment such as a fuel tank 13, battery 14, oil tank 15, etc., which are large parts, are arranged. A loading platform 16 is fixed at the upper position.

The space formed between the top surface of this loading platform 16 and the back of the backrest 9b is used as a luggage storage chamber 17, and the left and right sides from both sides of the loading platform 16 to the upper end of the backrest 9b are covered with the vehicle body and a series of covers. The rear part is open so that luggage 18 such as a helmet can be taken in and taken out, and the storage chamber 17 is made freely movable by a lid 20 pivotally attached to the rear end of the loading platform 16 by a hinge 19.

Therefore, when you sit on the seat 9, the driver 12 (
7) fil[112a naturally extends forward, and the foot 12b can be placed at any position on the 70a11.

Further, since the driver 12 can drive while leaning against the backrest 9b, there is no fatigue in the upper body, and combined with the freedom of where to place the feet, the driver's body can be driven for a long time with less fatigue. Since the center of gravity of the vehicle including the engine 5a is lowered, the running stability of the vehicle body is high and it is easy to get on and off the vehicle.

〔Effect of the invention〕

As explained above, according to this invention, since the floor is provided in front of the seat, the driver can place his/her feet in any desired position while driving, and unlike conventional methods, the driver can place his or her feet in any position that suits his/her physique. There is no need for a structure that requires adjustment,
The vehicle body structure can be simplified. In addition, there is no strain on the driving position due to the length of the driver's legs.
In addition, since a backrest is connected to the seats 1 to 1, the driver can lean on the backrest while driving, thereby reducing fatigue during driving. Since the floor including the horizontal unit 1-engine is located low in the car body, the center of gravity of the car is extremely low, increasing the stability of the car body, making it easy to get in and out of the car, and having a good footing while driving. Since the wheel is closer to the front, it is difficult to wheelie even during sharp acceleration, increasing safety. Furthermore, a space is created on the back side of the backrest, which can be used as a storage room for large items such as Bermetsu 1-.
