One standpipe 22 is for this seat cushion 21 expanding-contracting action on this seat portion 20;
(C) this link rod part 30 is to comprise at least:
One first connecting rod 31, the one end is established one first articulated part 311 (for example establishing a fast disassembly type bunching ring), supply outer tube surface 131 slippages of this end of this first connecting rod 31 with this first articulated part 311, and supply the swing on this vehicle frame pipe 13 of this first connecting rod 31 with this first articulated part 311 at this vehicle frame pipe 13; The end in addition of this first connecting rod 31 is then established one second articulated part 312 (for example establishing a fast disassembly type bunching ring), articulate for this first connecting rod 31 and this standpipe 22 with this second articulated part 312, and supply the swing on this standpipe 22 of this first connecting rod 31 with this second articulated part 312;
One second connecting rod 32, be to articulate with an end and this vehicle frame pipe 13 swings, and this end of this second connecting rod 32 is these first articulated part, 311 back that are articulated on this vehicle frame pipe 13, and go up prominent one group of ear 321 between an end of this second connecting rod 32 and other end, articulate for these standpipe 22 swings with this ear 321;
(D) trailing wheel 40 are the ends in addition that are articulated in this first connecting rod 32, and two damping wheels 41 is the axle center that are articulated in this trailing wheel 40 with identical angle of inclination;
(E) transmission group 50 (for example establishing a transmission wheel disc), be to be articulated between this end and this group ear 321 of this second connecting rod 32, and according to the swing of this second connecting rod 32 on this vehicle frame pipe 13, and this first articulated part 311 is in the slippage of these vehicle frame pipe 13 outer tube surfaces 131, and can move between a primary importance P1 and a second place P2;
When this transmission group 50 is positioned at this primary importance P1, triangular in shape substantially between this standpipe 22, this first connecting rod 31 and this second connecting rod 32 threes;
And this transmission group 50 is when being positioned at this second place P2, and this first connecting rod 31 is parallel with this vehicle frame pipe 13 substantially side by side, and this second connecting rod 32 then cardinal principle and this standpipe 22 is parallel side by side;
Be the telescopic bicycle of connecting rod of the present utility model so.
And the utility model is when reality is used, be as shown in Figure 2, at first, both hands are held the handle 11 of this headstock portion 10 and the seat cushion 21 of this seat portion 20, then, this headstock portion 10 is easily drawn back with this seat portion 20, come again, this first articulated part 311 is fixed on this vehicle frame pipe 13 that end near this second connecting rod 32, and this second articulated part 312 is fixed on this standpipe 22, at this moment, this transmission group 50 is to be positioned at a primary importance P1, and promptly can the utility model launching bicycle after fixing provides and drive.
And be to be widely used in different heights or the long rider of different leg, so, can from this headstock portion 10, do flexible up and down adjustment, allow the rider of different heights can optimal height to this handle 11 according to different riders' height, grip this handle 11, and the comfortable bicycle that drives; Certainly, this seat cushion 21 is done flexible up and down adjustment on this seat portion 20, then can allow the long rider of different legs can optimal height, take this seat cushion 21, and then the comfortable bicycle that drives.
See also shown in Figure 3ly again, in the time will storing this bicycle,,, promptly produce following the action simultaneously again with this headstock portion 10 and these seat portion 20 light backups as long as this first and second articulated part 311 and 312 is loosened:
[1] this first articulated part 311 by this end near this second connecting rod 32, slides onto that end near this headstock portion 10 on these vehicle frame pipe 13 outer tube surfaces 131.
[2] two ends of this first connecting rod 31 are the axle center with this first and second articulated part 311 and 312 respectively, relatively this vehicle frame pipe 13 and this standpipe 22 swings action.
[3] end of this second connecting rod 32, articulated section with this vehicle frame pipe 13 is that swing is done in the axle center, and the other end of this second connecting rod 32, seeing through this ear 321 is that swing is done in the axle center with the articulated section of this standpipe 22, and this second connecting rod 32 is in the process of swing, and drive this transmission group 50 and change to this second place P2, and drive this damping wheel 41 and change to vertical substantially by the angle of inclination by this primary importance P1.
The set aforementioned activities, make this bicycle be shrunk to this headstock portion 10 almost with this seat portion 20 length of closing mutually, and this front-wheel 12, trailing wheel 40 and two damping wheels 41 are to land simultaneously at this moment, so the time this bicycle be with extremely short vehicle commander, utilize four wheels steadily land (cooperation is consulted shown in Figure 4), can promote this bicycle by singlehanded directly pulsation-free, at any time this bicycle is stored in any narrow space and be beneficial to, cooresponding being convenient to stores, and volume is little so be beneficial to carrying and be nothing difficult especially.
Certainly, as shown in Figure 1, between the axle center of this first articulated part 311 and this transmission group 50, establishing a supporting member 60 (for example establishing a Shock absorber), then is the pivot joint degree of stability that can promote between this second connecting rod 32 and this vehicle frame pipe 13.
Below only be with preferred embodiment explanation the utility model, any simple modification of doing for previous embodiment, neither disengaging spirit of the present utility model and scope, and by above detailed description, can make and know this skill person and understand that the utility model can reach aforementioned purpose really, the real regulation that has met patent law proposes utility application.
