Abstract

PURPOSE:To allow a space to be formed in large volume by forming the baggage storage space, opened to the side of a car body, between an upper frame extending to the rear from a head pipe and a lower frame extending horizontally after lowering from the head pipe, in the case of a small vehicle of motorcycle or the like. CONSTITUTION:In the case the invention is applied to a unit swing type motorcycle 1 providing vertically swivelably a power unit 5, having a rear wheel 4, in the rear part of a car body, a car body frame A is constituted of a head pipe (a), lower frame (b) lowering from this head pipe (a) thereafter extending almost horizontally to the rear further extending diagonally to the upper and rear and an upper frame (d) extended to the rear from the head pipe (a) and connected to a diagonally upper rear extension part (c) of the lower frame (b). The car body frame A in the above supports to the lower of its diagonally upper rear extension part (c) the power unit 5 being able to vertically swing. And forming between the upper and lower frames (d), (b) baggage storage space 9 of almost tetragonal shape as viewed from the side, a baggage B of a helmet and a bag or the like is accommodated.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a small vehicle equipped with a unit swing type power unit.

(Background of the Invention) In small vehicles, particularly small motorcycles, there are various restrictions on the arrangement of luggage storage space, so it is difficult to secure a large capacity. Therefore, in a scooter-type vehicle that has a flat foot step installed below the steering wheel and the seat, a basket for storing luggage is provided above the foot step, and this basket is attached to the steering wheel. A device that locks and holds the lower leg shield and the vehicle body cover below the seat has been proposed (Utility Model Application No. 54-10175).
No. 8) However, if heavy items are stored in this space, the load applied to the body frame will increase, and the rigidity of the lower frame, which descends from the head pipe and passes below the foot step, will be insufficient. . For this reason, the lower frame had to be made thicker, which caused the problem that the space for storing luggage became smaller.Also, when the space for storing luggage became large and deep, it became difficult to put in and take out luggage. Problems also arise.

(Object of the Invention) As described above, the present invention provides sufficient rigidity of the vehicle body frame when providing a large-capacity luggage storage space above the foot step located below the steering wheel and the seat. To provide a small vehicle that can accommodate a large amount of space and facilitate the loading and unloading of luggage.

(Structure of the Invention) According to the present invention, the object is to provide a lower frame that descends from a head pipe that holds a front wheel, extends rearward almost horizontally, and further extends diagonally upward rearward; A unit swing type small vehicle including a power unit disposed below the exit part, the unit swing type small vehicle including an upper frame extending rearward from the helmet vibrator and connected to the diagonally upward rear extension part, and a This is achieved by a small vehicle characterized by forming a luggage storage space that allows articles to be taken in and out from the side of the vehicle body.

(Embodiment) FIG. 1 is a side view of a motorcycle which is an embodiment of the present invention.
FIG. 2 is a plan view, and FIG. 3 is a sectional view taken along line DI-[1].

In these figures, reference numeral 1 is a motorcycle, and a body frame A of this motorcycle 1 includes a head vibrator a,
A lower frame b extends rearward almost horizontally after descending from the head vibe a, and further extends diagonally upward rearward, and a lower frame b extends rearward from the head pipe a and is connected to the diagonally upward rearward extending portion C of the lower frame b. It has an upper frame d. The head pipe a holds a steering handle 2 and a front wheel 3 that is turned left and right by the handle 2. Further, a power unit 5 having a rear wheel 4 is provided below the diagonally upward rear extending portion C at the rear of the vehicle body so as to be vertically swingable, thereby forming a known unit swing type rear wheel suspension system. There is.

The lower frame b of the body frame A is largely bent downward between the steering handle 2 and the seat 6 when viewed from the side, and a substantially flat foot step 7 is provided at the bottom of this bent portion.

Further, the steering handle 2 and the seat 6 are connected almost linearly by a knee grip member 8 constituted by a fuel tank 8a and its cover 8b. As is clear from FIG. 3, the upper frame d is arranged near the center of the lower surface of the fuel tank 8a in the front-rear direction. Between this knee grip member 8 and the foot step 7,
That is, a cargo storage space 9 having a substantially rectangular shape in side view is formed between the lower frame b and the upper frame d. Here, the foot step 7 is located between the front wheel 3 and the power unit 5, and the volume of the space 9 is sufficiently expanded. Knee grip member 8
The upper frame d facing the lower surface of the fuel tank 8a forming a part of
is provided with a hook 9a, and the space 9 is used for storing luggage. 9b is the cap of the fuel tank 8a;
10 is a lubricating oil tank disposed in front of the fuel tank 8a;
11 is a storage battery arranged below the seat 6.
In the figure, B is luggage such as a helmet and a bag stored in the article storage space 9.

(Effects of the Invention) As described above, the present invention includes a lower frame that descends from the head vibe, extends rearward almost horizontally, and further extends diagonally upward and rearward, and a lower frame that extends rearward from the head pipe and extends diagonally above the lower frame. Since a cargo storage space is formed between the upper frame connected to the rear extension, the upper frame can sufficiently increase the rigidity of the body frame, and the lower frame can be made thinner. Thus, the capacity of this luggage storage space can be sufficiently increased. Furthermore, since the baggage storage space can be loaded and unloaded from the side of the vehicle body, it is easy to load and unload baggage even when the baggage storage space has a large capacity.
