Description

Shelf typed four-wheeled cycles

The utility model belongs to technical field of bicycles, particularly a kind of shelf typed four-wheeled cycles.

Existing bicycle is two-wheeled, tricycle, and two-wheeled, tricycle poor stability in the process of driving is difficult for driving, and they do not have shed, blow, rain, during Exposure to Sunlight can not to the user provide becalm, take shelter from rain, sun-proof place.

The purpose of this utility model is to design a kind of later-model shelf typed four-wheeled cycles at the above-mentioned defective of existing bicycle existence, and this bicycle good stability drives easily, and its shed is collapsible, and is easy to use, the article that portability is more.

Its technical scheme is that the feature of this shelf typed four-wheeled cycles is that it is by two front-wheels, two trailing wheels, support, actuating device, brake part, form, preceding window shade, steering wheel arrangement, seat, foldable shed, article case ten parts are formed, actuating device is by preceding sprocket wheel, back sprocket wheel, chain, foot-operated parts are formed, steering wheel arrangement is by tho wheel support, front-wheel support, sprocket wheel, turn to chain, the bearing circle parts are formed, foldable shedly cover two parts by frame and folding stand and canopy and form, two front-wheels are packed on the support by front-wheel support and tho wheel support, actuating device, two trailing wheels, seat, foldable shed, the article box part is packed on the support, and form and preceding window shade are packed on the front-wheel support.In order to alleviate the burden that people drive for a long time and ride when going up a slope, can on actuating device, be provided with the mechanical powered drive parts, as electrodynamic type or fuel oil type.Its horsepower does not need too big, does not need reverse gear or transmission system yet, and its moving velocity is controlled at below 30 li/hour and gets final product.Support is the vehicle frame of quadricycle, and it is four front and back wheel to be solidified as a whole and fixing or support the object of other parts.Actuating device is the parts that make bicycle walking by people's strength, and it still adopts existing cycle chain, sprocket wheel, foot-operated frame mode to realize.But laborsaving when driving, foot-operated force rod is a circular arc, because the length that has prolonged force rod is more laborsaving when driving.Brake part is the parts that the wheel of walking is stopped, and its adopts the form of existing bicycle brake sheet, all can with parking brake or service brake.Form is to supply the user of direction of operating dish to observe the place ahead ground-surface transparent window, and it is positioned at the place ahead of bearing circle.Preceding window shade is the curtain that plays the shading wind and rain effect that is positioned at the form below, its available cloth, rubber, plastics or other material manufacture.Steering wheel arrangement is to make the device that turns in this bicycle walking with bearing circle, and its adopts sprocket wheel, turns to the version of chain, bearing circle, controls that two front-wheel steerings realize.Seat is to use for grasping bearing circle and pedaling foot-operated people.Foldable shed is object folding, that can cover whole locomotive body after opening, and it is made up of frame and folding stand and canopy lid two parts, and frame is packed on the support, and folding stand and canopy cover and be packed on the frame.The article case is the chest of holding tool or other apparatus, can be provided with backrest on the top of article case, makes the article case become people than comfort seat.The use of this bicycle is simple, no longer here stating more.

This bicycle has effectively overcome the defective of existing bicycle, and it has good stability, easily drives, shed is collapsible, advantage such as easy to use, for the user provide one becalm, take shelter from rain, sun-proof, warming comfortable place, people and the elderly of its suitable especially region of no relief use.
