Abstract

The utility model relates to a bicycle, the carrying size of which is reduced by means of folding. Because shapes of parts in a bicycle are different and irregular, if the bicycle is folded according to a present usual way, the appearance of the bicycle is complex and irregular, the bicycle is inconvenient to carry, and the appearance is not beautiful. A bicycle crossbeam of the utility model is designed into a suitcase type, and therefore, other parts of the bicycle can be totally folded into the suitcase type crossbeam when folded. The utility model has the advantages of beautiful appearance and portability.

Description

Portable case type portable folding bicycle

The utility model relates to a kind of bicycle that reduces to carry size by method for folding.

Bicycle is one of vehicle the most frequently used in our actual life, and the technology of Regular Bicycle is at present: the bottom of the big fine strain of millet of rigidity about one pair long one meter, the pedal device that front and back wheel is housed and connects together with hinge wheel.The handlebar of vehicle seat and may command front-wheel direction is housed above the beam.Relative position between them by the support fixation of crossbeam.The people is sitting on the vehicle seat, hand steered handlebar controlling party to, pedal the logical chain gear of pedal, wheel just has been driven to rotate.It does not consume energy, and is free from environmental pollution, can also body-building, and be a kind of good short distance traffic instrument.If get on the car but want to carry it, stair climbing is because the relatively oversize meeting of size is very difficult.

For addressing this problem, common way is to be designed to the crossbeam of bicycle foldable, there is design one to roll over, also have two the folding, can make the length of bicycle be reduced to the 1/2-1/3 of original length like this because the component shape in the bicycle is different, irregular, it is uneven to fold inevitable complex contour with this usual way, carry very inconvenient, also not attractive in appearance.

The purpose of this utility model provides a kind of improved collapsible bicycle that is convenient for carrying.It is should have present bicycle convenient and strength-saving province can advantage, can be folded into again suitcase equally size be easy to carry with style.

The purpose of this utility model is to realize like this; The crossbeam of bicycle is designed to the formation of suitcase, the form of suitcase and the function that function has the bicycle crossbeam are again promptly arranged; Do not needing by bike when folding, box crossbeam is altogether collapsible as suitcase, and two halves profile altogether can be as the size of suitcase and smooth.When needing by bike, two semi-open with case, and the hinged lock jail, chest just become one firm, the car beam that length is the same with the big beam length of ordinary bicycle.Meanwhile the parts that the bicycle crossbeam is linked will be set as follows; At first, left and right sides pedal and hinge wheel are separated, but be designed to the structure of conveniently assemble and disassemble.Bicycle is wanted the time spent, about two pedals can be fixed on two of hinge wheel, they can together be rotated; The time spent can not separated left and right sides pedal, disassemble, and embeds suitable position in the box crossbeam.Support, the handlebar of next vehicle seat, front and back wheel support and crossbeam all link by rotating shaft and make them can fold into box crossbeam inside.Wherein, vehicle seat, trailing wheel and hinge wheel are contained in the half of case, and front-wheel and handle are in second half.When needing use car, then being deployed into control position with upper-part, and lock is firm, so just can work as ordinary bicycle; When folding, they can make each folding means convex-concave alternate by the inside of each rotating shaft rotation inlet formula crossbeam, arrange in order, and the two halves of box beam can be closed up smoothly.In addition, for reduce about handle between size, about the centre also connect into adjustablely with having the lock screw hinge so that before handlebar is folded box fine strain of millet, left and right sides handle can earlier and be arrived together.

The utility model makes the not only folding back of bicycle size very small and exquisite owing to designed the structure and the multiple foldover design of relevant parts of box crossbeam, and the while external form is also as combination lock commonly used, and is elegant in appearance, is easy to carry.And after launching the same with ordinary bicycle be the convenient and swift province of people can the vehicle.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.

Fig. 2 is the front view of the utility model when organizing work.

Fig. 3 is the front view after the folding mould assembling of the utility model.

Fig. 4 is the left view that Fig. 3 reflects inner major part relative position after its mould assembling.

Fig. 5 is [4] [5] [6] detail assembly drawing among Fig. 2.

Fig. 6 is the right elevation of Fig. 2 parts [7].

Describe details service condition in detail below in conjunction with Fig. 1-Fig. 6 according to the concrete device that the utility model proposes.

This device comprises a box crossbeam [1], by rotating shaft [10] and box beam [1] bonded assembly rear wheel [2], be connected vehicle seat [3] by rotating shaft [11] with box beam [1], by the hinge wheel [4] of bearing fixing in [1] inboard, the detouchable left foot is pedaled [6], right pedal [5], left and right handles is also arrived together, and then fold into the handle [7] of box beam [1] by rotating shaft [12], can fold into the front vehicle wheel [8] of box beam [1] by axle [13], in order to prevent in operation and the loosening expansion tightening wheel [9] of chain in folding.

Fig. 2 is the front view of this device when organizing work, and in the time of folding, at first left foot is pedaled [5], and right pedal [6] separates, takes off with hinge wheel [4], puts the inboard position of depositing pedal specially of box crossbeam [1] into and puts the jail; Make then handle [7] about holding together together by the direction of arrow E, F among Fig. 6; Then press the steering handle vehicle seat [3] of Fig. 2 arrow A, B, C, D indication, handle-bar [7], the inboard suitable position that folds into box crossbeam [1] that rear wheel [2] and front vehicle wheel [8] are orderly, expansion tightening wheel in this process [9] unlikelyly split away off it all the time from sprocket wheel; Unclamp the screw that tightens up at box beam [1] hinge place this moment, its two halves altogether, has been exactly folding portable bicycle one profile of seemingly suitcase as shown in Figure 3, and this moment, the arrangement of its inner major part was seen shown in Figure 4.Can expand into the mode of operation of Fig. 2 from Fig. 3 state if connect this step inverse operation in the past.
