Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem wherein the main purpose of a conventional bicycle is riding, and it cannot be brought in other means of transportation in principle, or must be brought in after being folded, and is not suitable for conveying cargos, and its use applications are limited since few objects have the shape to be accommodated in a bicycle body. <P>SOLUTION: A bicycle is integrated with a trunk, and has a conventional pedal type or longitudinal rowing type for power transmission of the bicycle. The function of the bicycle is miniaturized, the bicycle is accommodated in the trunk, and the internal volume as the trunk function is efficiently used. Further, by folding and accommodating projections of the bicycle part, the appearance thereof looks a trunk, and can be brought in other means of transportation. Thus, the bicycle is provided, which has both the bicycle function and the trunk function. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

The present invention is a bicycle having a trunk function that combines a bicycle function and a trunk function, adds a luggage storage function and a transport function, facilitates indexing, transport and carrying, and can also be used as a bicycle function.

Conventional bicycles are mainly used for riding, and when carrying luggage, it can be carried by placing it on the front bag and rear luggage table, but there is a limit on the load capacity, and the luggage table is high and has a center of gravity. It becomes so expensive that the stable ride is bad and it is difficult for anyone to carry luggage easily.

General bicycles are not allowed to be brought in by other means of transportation (train bus, etc.). There are small folding types to facilitate carrying, but there are many protrusions, so there are many protrusions and they are stored and lifted each time. It is not possible for anyone to get on the transportation.

Baggage, handbags, etc. are put in a bag provided at the front, but there is a risk of snatching.

By eliminating the above-mentioned problems caused by the limited use of conventional bicycles, it is easier than ever to travel, commute, shop, and other various means of transportation and transport a large amount of luggage. The challenge is to play a part in reducing traffic by using transportation.

By using the pedal system in the heel direction, the range of movement is minimized, and by keeping the drive train in the horizontal direction, a place for the trunk to be installed under the saddle and between them is secured.

The steering system middle part and the drive system are housed in the inner surface of the trunk, and the handle and pedal are foldable and have few protrusions, improving handling and safety during towing and transportation.

The steering wheel can be fixed at any height that is easy to drive in the bicycle mode, and when it is lowered to the bottom, the steering angle is fixed, making it easy to prevent damage to the steering system and handle transportation.

If the caster roller installation side is at the bottom and the tow grip is at the top, the towing can be performed in the same way as a conventional travel case. It can also be pulled with the center grip even in bicycle mode.

By using a pedaling system, it is possible to achieve both a travel trunk and a bicycle function, and it is also possible to reduce the size and weight. For example, driving from the departure point to the station etc. as a bicycle and using other transportation such as public railways and buses In that case, you can carry it as a travel trunk and drive as a bicycle again from the station to the destination. It is also possible to get off the road and on the road, store it in the trunk and move it when there is an increase in baggage due to shopping or other reasons.

Since it is possible to carry luggage in and out of each facility and carry it, it is safe for crime prevention such as theft, and it can be stored indoors in each facility like a travel case, so there is no need for a separate parking lot and inconvenience to others Decrease.

Luggage can be locked in the trunk to prevent damage such as hitting.

Because it has many surface parts, it can be used for advertising and photovoltaic power generation.

A preferred embodiment of a bicycle having a trunk function according to the present invention will be described below in detail with reference to the accompanying drawings. A steering system as a bicycle will be described with reference to FIG. The handle inner stem 1f is inserted and fitted into the fork outer stem 2b that penetrates the head tube 3 of FIG. The fitting part is not a concentric circle but can be inserted and fitted with an ellipse, a protrusion guide or a polygon, so that it is possible to easily adjust the height without changing the angle between the handle and the fork 2c each time the handle height is changed. When changing the handle height, the handle height can be adjusted to any position by operating the fork stem lock lever 2a shown in FIG. Since the steering system can be easily adjusted, the bicycle function is satisfied, and the user sits on the saddle 7b shown in FIG. In the case of moving by index without riding on the bicycle, a stable index can be obtained by setting the handle portion to the minimum height and indexing the center grip 1c of FIG. Alternatively, the tow grip 4 shown in FIG. 1 provided at the front can be pulled out.

Unlike a conventional rotary pedal, the power transmission method for bicycle driving employs a vertical motion reciprocating pedal of the pedal 6 shown in FIGS. As a mechanism for converting the vertical reciprocating motion into the rotational motion of the rear wheel, the horizontal reciprocating motion is converted into the rotational motion by transmitting the vertical reciprocating motion to the rotation rotating device 6b in FIG. The transmission 6c transmits power to the rear wheels as a rotational motion. The pedal 6 can be moved in the left-right direction and can move vertically or independently, and can also be operated on one foot.

As a pedal driving assistance, a driving assistance by the drive motor 13 can be provided by the storage battery 14 to facilitate the bicycle running function.

In the case of small items such as daily shopping as an accommodation method as a trunk function, the saddle 7b in FIG. 2 is accommodated in the pocket 7e by opening it in the direction of the arrow. In the case of a large amount, in order to use and store the trunk function, the key device 12 of FIG. 1 is unlocked, the trunk lid 7f of FIG. 1 is opened, and a large amount of objects are stored in the trunk inside 7a. FIG. 3 shows a state in which the trunk lid 7f is opened in the direction of the arrow. Even when a large amount is stored in the trunk, it can be transported using the bicycle function.

Conventional bicycles cannot currently be brought into public transportation such as trains and buses, but can be carried as a trunk by transforming a bicycle with a trunk function into a trunk shape. As a modification method, in order to fit the protrusions of each component when using the bicycle within the outer dimensions of the trunk, the handle portion of the bicycle is folded by loosening the fork stem lock lever 2a of FIG. 4 and the handle grip 1a shown in FIG. 4 protrudes left and right before folding, but the handle grip lock lever 1b shown in FIG. Folding in the direction of the arrow can fit within the trunk dimensions. The pedal also protrudes left and right as shown in FIG. 4, but can be stored within the width of the trunk by folding the pedal 6 upward (in the direction of the arrow). When the projections are folded and fit within the trunk outer dimensions and transported as a trunk, the caster roller 7c of FIG. If the projection is completely folded, it can be covered with a simple cover to eliminate the risk of touching the folded parts.

When you always use it as a bicycle and store it in a bicycle parking lot, you can fold each protrusion and store it in the trunk state to save space. When storing in the state of a bicycle, the side stand 10 of FIG. 1 can be pulled out for easy storage.

It is an external appearance side view which shows the arrangement | positioning relationship of each apparatus of the bicycle provided with the trunk function. It is sectional drawing which shows the storage relationship of the bicycle provided with the trunk function, and the arrangement | positioning relationship of a driving force transmission apparatus. It is the top view which shows the state which opened the trunk and the plane which looked at the bicycle provided with the trunk function from the upper surface. It is a front view which shows the state of the folding storage of the front of the bicycle provided with the trunk function, and each projection component.
