Description

Folding multifunction bicycle

The utility model relates to a kind of Foldable multifunctional bicycle.

At present, various bicycle styles are more, but mostly the form fixed volume is big; Collapsible bicycle, or function singleness, or the complex structure variation is inconvenient, and moulding is not attractive in appearance, poor practicability.

The purpose of this utility model is to provide a kind of flexible, multi-functional, little portative multifunctional foldable bicycle of volume after folding that changes simple and reliable for structure, folding, provides a kind of comparatively desirable walking-replacing tool for travelling at home.

The utility model comprises front vehicle body, aftercarriage and the dual vertical crossbeam that the front and back car body is linked up.Current aftercarriage relatively rotates and three folding back shelf is launched itself and preceding shelf are articulated, and handlebar is inserted on the dual vertical crossbeam just can forms the baggage car shape again, castor before and after further falling, baggage car just becomes the wheelchair shape.Current aftercarriage unclamps handlebar and makes its below that forwards the dual vertical crossbeam to, and fall vehicle seat after same direction rotation is drawn close mutually, and bicycle just is minimum folded formation cumuliformis.

The utility model is owing to adopted the front and back car body by the joining structure of dual vertical crossbeam, both guaranteed that bicycle had failure-free intensity, can realize the folding of multiduty variation and minimum volume again,, be easy to apply so the utlity model has higher utility.

Accompanying drawing is a constructional drawing of the present utility model.

The utility model is realized like this: by front vehicle wheel ［ 20 ］, preceding shelf ［ 19 ］, front fork ［ 24 ］, preceding fork shaft ［ 16 ］, preceding pivoted frame ［ 17 ］, front rotary shaft ［ 25 ］, front fork axle head handlebar socket ［ 11 ］, handlebar plug ［ 13 ］, handlebar ［ 14 ］, front truckle ［ 21 ］, front truckle poles ［ 23 ］ etc. are formed front vehicle body, by rear wheel ［ 1 ］, three folding back shelf ［ 2 ］, vehicle seat core bar ［ 5 ］, back pivoted frame ［ 27 ］, back rotating shaft ［ 6 ］, rear truckle ［ 29 ］, pedal sprocket wheel ［ 28 ］, chain ［ 30 ］, minor sprockets ［ 31 ］ etc. are formed aftercarriage, the front and back car body links by dual vertical crossbeam ［ 10 ］, by preceding pivoted frame set pin ［ 26 ］ and back pivoted frame set pin ［ 7 ］ the front and back car body is positioned to become the bicycle shape on the same straight line.Behind the pivoted frame set pin ［ 26 ］ and ［ 7 ］, the front and back car body can be that rotate in the center of circle with front rotary shaft ［ 25 ］ and back rotating shaft ［ 6 ］ respectively before and after mentioning.When current aftercarriage relatively rotates respectively with the dual vertical crossbeam at an angle of 90, three folding shelf ［ 2 ］ are launched, back shelf hooks ［ 3 ］ are articulated mutually with preceding shelf hook base ［ 18 ］, unclamp handlebar plug set pin ［ 12 ］ simultaneously, insertion crossbeam handlebar socket ［ 9 ］ after fork shaft end handlebar socket ［ 11 ］ is upward extracted out in the past with handlebar ［ 14 ］, this moment bicycle the baggage car shape, handlebar is the baggage car handle, unclamp vehicle seat core bar bolt of rear end plate ［ 4 ］ and front truckle bolt of rear end plate ［ 22 ］ on this basis, put down before and after castor then bicycle just become the wheelchair shape, handlebar is the backrest of wheelchair, and vehicle seat (8) is the handrail of wheelchair.Current aftercarriage to same direction rotate draw close mutually after, handlebar is inserted on the crossbeam socket ［ 9 ］, unclamp handlebar bolt of rear end plate ［ 15 ］, make handlebar forward dual vertical crossbeam downside to and fall vehicle seat, then bicycle is minimum folded formation cumuliformis.The utility model can adopt coaster brake also can adopt cable brake, and transmission system can be installed.

Claims (1)
