Abstract

The utility model relates to a folding mini bicycle for adults, which relates to a vehicle. The utility model is composed of a telescopic frame 1 (picture 1), a movable frame 2, two sections of telescopic seat cushion support frames 3, a movable seat cushion 4, two sections of telescopic handle bar straight tubes 5, a torsion pedal axle 6, a frame cross beam 7, a central axle 8, a joint 9, a joint 10, a front wheel 11, etc. When all components are expanded to the furthest end, the utility model has the riding function like the common bicycle; the folded outline volume is shortened under 0.1 < 3 >, which is convenient to carry and store in trains or ships for free.

Description

Mini bicycle

The utility model belongs to the vehicle

Existing bicycle is a kind of walking-replacing tool, but it is bulky, and self is heavy, transports, carries, deposits quite inconvenient.

The purpose of this utility model is exactly will be by the combination of a series of ingenious, flexible, little shape parts, makes below bicycle volume-diminished to 0.1 cubic meter behind the folding, so that deposits, transports, carries more convenient.And can ride as ordinary bicycle after launching.

The technical scheme of existing accompanying drawings miniature bike described in the utility model.

Flexible vehicle frame 1 is small one and large one two pipes that insertable cross section is a rectangle, and movable carriage 2 is arranged on it, with middle right overhead 8, can reverse step stalk 6, crossbeam 7 and trailing wheel, blockchain, ratchet etc. on the movable carriage 2.Tail end at flexible vehicle frame 1, device has the scalable cushion rack 3 of pronunciation and meaning shape two joints, 3 top be connected with can before and after movable seat cushion 4, the top of flexible vehicle frame 1 then connects the handlebar straight tube of being made up of the scalable garden of two joints pipe 5, the not end of straight tube 5 has rotatable 90 ° joint 10, and what land down then is front-wheel 11 again.

When each parts of miniature bike were launched to be stretched to distal-most end, this car can be ridden as ordinary bicycle.

But if with each parts folding, be about to movable carriage 2, flexible vehicle frame 1 all is pushed forward to the top, movable seat cushion 4 is forward by foot, and the scalable cushion rack of two joints is pressed onto the end, and joint 9 is changeed 90 °, joint 10 is changeed 90 °, handlebar straight tube 5 is concordant with vehicle body, can reverse step stalk 6 and also change 90 °, and then full vehicle body just becomes accompanying drawing 2 shapes.

The great advantage of the existing bicycle of the utility model is foldable arriving below volume 0.1 cubic meter, can put in the fabric travelling bag, and it is very convenient to carry stair activity like this, for living high-rise resident not less than being a Gospel; Vehicle or boats and ships are not violated the regulation of " freely carrying luggage " because volume less than 0.1 cubic meter, is therefore taken pubic transport, and can freely carry; In depositing,, can hang on the wall or fill under bed also because of volume behind the folding is little; It is also minimum to launch the back profile, not only can ride as ordinary bicycle, also luggage and articles can be suspended from the vehicle frame, can pass through station, the narrow and small ticket barrier of harbour, to replace baggage car; Flexible operation does not need instrument in folding and expansion in addition, is the big advantage of one yet.

Description of drawings is as follows:

Fig. 1 launches the back front view for miniature bike

Fig. 2 is a front view behind the miniature bike folding

Among the figure

The 1-vehicle frame 2-movable carriage of stretching

The scalable cushion rack 4-movable seat cushion of 3-two joints

The scalable handlebar straight tube 6-of 5-two joints can reverse the step stalk

Right overhead among the 7-cross member of frame 8-

10-joint, 9-joint

The 11-front-wheel

The utility model is real to be ingenious combination and the improvement of the part of existing bicycle, all can utilize off-the-shelf such as ratchet, blockchain etc., vehicle frame, front and back wheel can be improved existing perambulator, therefore realize that best way of the present utility model is that Bicycle Plant or perambulator factory practice midwifery.

Claims
