Abstract

The utility model relates to a foldable touring bicycle, belonging to the non-mechanized vehicles technology field. The bicycle includes wheels arranged on the both extremities of the frame and a pedal chain actuator arranged on the middle lower part of the frame, wherein two lockable folding units for separating the bicycle body into three parts is mounted on the frame. When the bicycle is commonly used, the bicycle body is formed as a line, while when it needs to be put away or carried, the bicycle is folded along zigzag and locked, forming a 'n shape', and thereby the whole bicycle is formed as a small go-cart with two parallel wheels. Using the smart concept of this utility model, the bicycle is capable of being folded more compact, convenient to be put away or carried; simultaneously, this bicycle has multi-functions because it can be used as a small go-cart. Expectedly, people will give it a warm welcome when the utility model is put to the market.

Description

Multi-functional three folding touring bicycles

Technical field

The utility model relates to a kind of multifunction bicycle, and especially a kind of folding touring bicycle belongs to the non-power-driven vehicle technical field.

Background technology

Bicycle is modal running vehicle.As everyone knows, existing common bicycle mainly is made up of wheel that is installed in the vehicle frame two ends and the foot-operated chain drive that is installed in position, vehicle frame middle and lower part.Though bicycle has brought many facilities to the mankind, in use also there are some inconveniences.For example, occupy, therefore carry and deposit inconvenience than large space.

In order to overcome this shortcoming, the someone has invented can folding of bicycle.This bicycle be owing to can folding the volume that has dwindled when carrying and depositing, but has only place's foldable structure usually, and purposes is single, and therefore still having can improvements.

Summary of the invention

The purpose of this utility model is: but the improvements that exist at prior art, and it is littler to propose a kind of volume after folding, thereby carries and deposit multi-functional more easily three folding touring bicycles.

In order to reach above purpose, multi-functional three folding touring bicycles of the present utility model comprise the foot-operated chain drive that the wheel that is installed in the vehicle frame two ends, middle vehicle frame support pulley gear, empty gear reversing device and be installed in position, vehicle frame middle and lower part, and wherein said vehicle frame has two places vehicle body to be divided into three sections the directed foldable structure of lockable.

During normal the use, foldable structure launches locking, and vehicle body can be ridden freely as common bicycle in line.When needs were deposited or carry, it is folding that vehicle body is " it " font, and the vehicle body compactness after this moment is folding is small and exquisite, and it is very little to take up space.When becoming " П " font to fold vehicle body and locking, car load forms the parallel waggon of a two-wheeled, can loading carry out.

This shows that the utility model makes the more compact structure behind the bicycle folding, thereby is more convenient for depositing and carrying with design cleverly; Simultaneously, can also use, possess multiple function as waggon.After estimating to release, people's popular welcome will be subjected to.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is an embodiment deployed condition of a utility model structural representation.

Fig. 2 is Fig. 1 embodiment " it " font folded state structural representation.

Fig. 3 is Fig. 1 embodiment " П " font folded state structural representation.

The specific embodiment

Embodiment one

The multi-functional three folding touring bicycles of present embodiment as shown in Figure 1, mainly by front vehicle frame 1-4, back vehicle frame 1-1, intermediate link support 1, be installed in the wheel 2,3 of forward and backward vehicle frame, and the foot-operated chain drive on the vehicle frame middle and lower part 1-1 of back 5 constitutes.Two places are provided with lockable foldable structure 1-3 and 1-2 before and after on the crossbeam of vehicle frame 1, before, during and after vehicle body 1 is divided into three sections.

In conjunction with Fig. 1,2 and 3 as can be seen, foldable structure 1-3 and 1-2 are inserted and are hinged on the single head steering knuckle in the abutment and single, doublely constitute to activity locking joint by tenon.

In conjunction with Fig. 1,3, middle vehicle frame link frame 1 is provided with the mechanicalness spring and rises and falls and support pulley bracket structure 8, has go-cart and slides supporting role, parks the car supporting role again.

In conjunction with Fig. 1, Fig. 3,6 are provided with neutral gear and slide structure when being folded into go-cart, make foot-operatedly not answer backward and hinder.

In conjunction with Fig. 1, Fig. 3,7 are provided with and are folded into go-cart handle structure when being folded into go-cart.

Fig. 3 also is equipped with collapsible car basket 9 in trailing wheel 3 one sides in addition.Generally, foldable structure launches, and vehicle body locks in line, as shown in Figure 1, and can be as riding ordinary bicycle as running vehicle.When needs were deposited or carry, as shown in Figure 2, it is folding that vehicle body is " it " font, and this moment, vehicle body took up space very for a short time, can be placed in the power actuated vehicle such as automobile, offered convenience to the car owner, also can carry along with knapsack, used when particularly being fit to travel outdoors.When as shown in Figure 3, vehicle body is become the folding locking of " П " font, and put down the folded bicycle basket, but car load forms the parallel loading waggon of a two-wheeled, be fit to very much the elderly's use of buying vegetables or remove supermarket shopping in the food market.

In addition to the implementation, the utility model can also have other embodiments.For example, can further foldable structure be set at handlebar 4 middle parts, like this can be when needed with leading doubling, thus make after folding compacter small and exquisite.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
