Description

Bicycle for children
The utility model belongs to bicycle, particularly belongs to child's bicycle.
Existing child's bicycle, no matter be three-wheel or two take turns all with to become person bicycle the same, drive wheel revolutions by the widely different commentaries on classics/crank motion of the bipod transmission device by crank connecting link or other various types, thereby bicycle advanced.Basically be in metastable state as for the rider that is sitting on the saddle.This mode of riding lacks the entertaining of playing for young children of year.
The purpose of this utility model is to provide the action of a kind of preceding updip of nationality rider and the similar vaulting-horse that face upward down the back to make the child's bicycle of vehicle forward/backward.
The object of the present invention is achieved like this: the child's bicycle of a kind of front-wheel that comprises handlebar, has steering hardware, vehicle frame, saddle and trailing wheel is characterized in that trailing wheel is fixed on the hind axle with crank; Be hinged on the treadle on the vehicle frame in the middle part of being provided with; The saddle bottom be respectively arranged with the connecting rod that links to each other with above-mentioned crank, with vehicle frame pivotally attached fork and with above-mentioned treadle one end pivotally attached strut.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is the signal that structure saddle shown in Figure 1 is in nadir.
Fig. 3 is a structure birds-eye view shown in Figure 1.
Fig. 4 is the single rear wheel structural representation.
Embodiment 1.As shown in figs. 1 and 3, the utility model is a kind of child's bicycle of tricycle structure, and it comprises handlebar 1, vehicle frame 3, saddle 5, the front-wheel 13 with steering hardware and trailing wheel 10 and 16.Trailing wheel 10 and 16 is separately fixed on hind axle 9 and 17.Crank 78 is captiveed joint with 17 with hind axle 9 respectively with 14 by being arranged on cranking arm of its two ends symmetrically.Two back vents 11 of vehicle frame 3 and 15 are bearing in respectively on hind axle 9 and 17.Saddle 5 bottoms are respectively arranged with fork 2, strut 4 and connecting rod 6.Connecting rod 6 one ends and saddle 5 hinges are pressed, and the other end links to each other with crank 7.Fork 2 one ends and saddle 5 are rigidly connected, and the other end is hinged on the vehicle frame 3.Vehicle frame 3 is provided with treadle 12.Treadle 12 middle parts and vehicle frame 3 are hinged.The forebody of treadle 12 is that the left and right sides is dichotomous, and the front end of bifurcated can be provided with pedal, so that children's biped is shelved and firmly.The two ends of strut 4 are hinged with the rear end of saddle 5 and treadle 12 respectively.When riding, both feet firmly scrunch bar 12 downwards, and saddle 5 will rise straight extreme higher position of ending as shown in Figure 1 by position shown in Figure 2 to the front upper place with the four-bar mechanism of being made up of vehicle frame 3, treadle 12, strut 4 and fork 2.Because of saddle 5 is to be rigidly connected with fork 2, so saddle 5 becomes a front rake with horizontal surface, rider leans forward with saddle 5.In the motion process of above-mentioned saddle 5, drive cranks 7 rotations by connecting rod 6, thereby two trailing wheels 10 and 16 that are fixed on hind axle 9 and 17 are rotated.After saddle 5 rose to the extreme higher position, biped loosened, and saddle 5 is subjected to the rider action of gravity and descends to the back lower place, until extreme lower position as shown in Figure 2.At this moment, saddle 5 becomes the elevation angle, a back with horizontal surface, and rider is also with extremely layback.With the decline of saddle 5, by connecting rod 6, crank 7, crank arm 8 and 14, hind axle 9 and 17 drives trailing wheels 10 and 16 and continues rotation.As for the direction of trailing wheel rotation (being advancing or retreating of vehicle), when then looking initial motion, cranking arm 8 and 14 residing positions and decide.Like this, in the travel process, the health of rider is constantly located an alternating state that rises and to lean forward and to descend layback in the position, and the action of similar and vaulting-horse has increased the enjoyment of riding.Connecting rod 6 and crank 7 can be that single pole also can be two bars of symmetry.
Embodiment 2.As shown in Figure 4, this is the signal of the utility model single rear wheel structure.The handlebar 1 that it comprised, fork 2, the front-wheel 13 with steering hardware are all identical with structure shown in Figure 1 with saddle 5.Compare with embodiment 1, the distance between two back vents 11 of its vehicle frame 3 and 15 has been dwindled.Unique trailing wheel 23 is fixed on the hind axle 22.Two back vents 11 and 15 respectively at trailing wheel 23 two-side supportings on hind axle 22.The two ends of hind axle 22 be provided with symmetrically respectively the band crank 20 and 25 crank arm 21 and 24.Saddle 5 bottoms are provided with Jiong shape link span 27.One end hinge knot on crank 20 and 25 pair of links 19 and 26 the other end and shape link span 27 tangle.Treadle is arranged on vehicle frame 3 bottoms.Above-mentioned treadle middle part and vehicle frame 3 hinge knots.It is dichotomous that the two ends of treadle are the left and right sides; The top of anterior left and right sides bifurcated is provided with pedal, the hinged strut that is provided with in the end of the left and right sides, rear portion bifurcated.The other end of above-mentioned two struts is hinged on the both sides of Jiong shape link span 27 respectively.Fork 2 and 27 anterior linking to each other of Jiong shape link span.
The utility model has changed traditional cycling mode.In the process that children ride, the wobbling action that is attended by the lifting of health and leans forward, swing back has strengthened the enjoyment that children ride.
