The specific embodiment

The people who rides bicycle always wishes that the bicycle of being ridden is comfortable, limbs are flexible, and the position of people on the seat of riding bicycle this moment is extremely important, and the optimal design size that this depends primarily on bicycle rack also needs specific tire height.

Please refer to Fig. 2, bicycle of the present utility model is made up of vehicle frame and wheel.Wherein vehicle frame comprises handlebar 1, seat 2, supports 3; Wheel comprises front-wheel 6 and trailing wheel 7, is made of wheel rim and tire respectively.Handlebar 1 and seat 2 vertically Height Adjustable.

Please together with reference to Fig. 3 to Fig. 5, wherein, Figure 3 shows that bicycle handle bar's 1 structural representation, wherein dotted line is represented handlebar 1 position change.Handlebar 1 is two bar handlebars, comprise be parallel to each other and vertical first bar 10 and second bar, 11, the first bars 10 and second bar 11 between connect by the rigidity connecting rod 13 of a weak point, connecting rod 13 1 ends are provided with a coupled structure 14.But this coupled structure 14 comprises the loosening vertical hole of spiral that is arranged on the rigidity short connecting rod and is used to hold second bar 11, also comprises a screw rod latch-up structure (as Fig. 4).Thereby vertically upper and lower mobile being locked by this latch-up structure of second bar 11 makes handlebar 1 vertical shifting.The surface 17 of second bar 11 is the nodular surface, is provided with small embossment, is beneficial to fix, and its end is provided with rubber bush 18, prevents that bicycle rider is injured because of carelessness.Handle 16 is fixed on second bar 11 by latch-up structure 15, this latch-up structure 15 is a screw-rod structure in the present embodiment, loosening latch-up structure 15, handle 16 can be with respect to being locked by latch-up structure 15 after 11 rotations of second bar again, second bar 11 can reversally insert in the vertical hole of coupled structure 14 fixing, and the position can be adjusted up or down equally, with reference to Fig. 5.Second bar, 11 counter-rotating backs are fixed in the coupled structure 14 with its end, simultaneously handle 10 are rotated to the extreme higher position again by latch-up structure 15 lockings, handlebar 1 is adjustable to higher position like this.

Please refer to Fig. 6, bicycle rack also comprises bracing frame 3, and this bracing frame 3 mainly is made up of tubular member, comprise down pipe 30, push pipe 31, on manage 32, seat tubes 33, seat stay 34, and chain supports 35 and fits together mutually.Last pipe 32 and seat stay 34 are coaxial and be positioned on the bevelled coaxial line of either side of terminal both sides of the seat tubes 33 of placing of tilting for how much.Manage 30 end and chain down and support an end of 35 and be installed in the either side of both sides, described seat tubes 33 bottom, and extend in the same level of pipe 32 and seat stay 34, on manage 32 and manage other two end of 30 down and be fixed on the push pipe 31.And will go up as far as possible pipe 32 and down pipe 30 make the geometry of vehicle frame be suitable for middle-sized tire and wheel rim near being installed on the highest as far as possible position of push pipe 31 upper ends, in the present embodiment with 20 inches wheel rims and tire size.Therefore can keep the height of center shaft from pedal 42 extreme lower position also to be fit to minimum children, and the height of scalable seat 2 and handlebar 1 is to be applicable to the adult to the seat.

Vehicle frame also additionally is provided with a seat pillar (not shown) telescopically and cooperates with seat 2, and seat pillar further extends by screw rod or flexible coupling energy, and firm (not shown) can tightening seat pillar is further fastening as bolt and nut.Make small children or the adult can be cosily by bike by tiny adjusting.Handlebar 1 also can slide and be identical with the adjusting degree of freedom at seat, but its free motion in addition the counter-rotating the position also allow, be to obtain more position to 1 at this moment by two parallel bars, 10,11 guide vehicles.

The rigidity connecting rod 13 of aforementioned weak point stretches out from the last end of push pipe 31, and first bar 10 is then sheathed and be installed in the junction of the following pipe 30 and the last pipe 32 of push pipe 31 upper ends.

Generally speaking, in the design of bicycle with when making, the vehicle frame size degree of dip of length, tubular member (highly) becomes multiplication relation with anthropological measuring, and each manufacturer is all different, depends on the coefficient difference of being got.The degree of dip of seat tubes 33, on manage 32 and seat 2 according to the vehicle frame size design, and the setting of the position at seat 2 is coefficients that the contriver invents voluntarily or prior art with respect to the degree of dip of seat tubes 33.

In order to design a general-duty bicycle rack, the essential physical dimension of determining vehicle frame, seat and the transformable position of handlebar, these determining dimensions depend on the physiological parameter that detects and monitor the people who rides bicycle, come the position of mark limbs and angle forming optimum value with optical detection system, and change in location that can be by regulating seat 2 and handlebar 1 is up to obtaining the numerical value that common sports medical science is recommended.

The child age of minimum can be comfortable at 4～6 years old (12 inches the child's bicycle that is equivalent to prior art) and do not ride not difficultly when the design of vehicle frame made the seat be in extreme lower position.At minimum seat position, the parallel bar on handlebar both sides also is adjustable to extreme lower position.For making bigger children with identical bicycle, two bars 10,11 of handlebar 1 can raise, and seat 2 raises by the rising seat pillar simultaneously.So, promptly be applicable to 6～8 years old children's (16 inches bicycles that are equivalent to prior art) with a bicycle, also be suitable for 8～12 years old children's (20 inches bicycles that are equivalent to prior art).

The utility model adopts a middle-sized child's bicycle to be used for the individuality at various ages, consider that adjusting handlebar 1 and seat 2 do not change the size of tire and framework to be fit to body sizes, vehicle frame of the present utility model has member pivot joint and/or extendible and connects seat 2 and handlebar 1.Like this, the people who rides bicycle can be in the best state of pedaling of stepping on, balance and on the seat, not moving well, thus do not waste muscle power.
