Abstract

The utility model discloses a both feet alternative pedaling type scooter, comprising a handlebar, a frame, front wheels, back wheels and double pedals, wherein, the double pedals which are arranged on the frame can be automatically reset, and the pedals drive connecting rods to move downwards; shifting teeth at one end of the connecting rod shift a ratchet at the bottom of the frame to drive a front driving shaft to rotate, and a ratchet on the front driving shaft and a chain transmit the pedal force to a ratchet on a back wheel shaft; and then the back wheels are driven to drive the scooter. The alternative pedaling of both feet is in line with the walking rule, and the utility model has simple structure and small volume, and is used for recreational fitness, and is suitable for indoor and outdoor use.

Description

Both feet are stepped on the formula scooter mutually
Technical field
The utility model relates to a kind of by human body legpower scooter voluntarily, particularly relate to a kind of both feet mutually the mode of stepping on drive the transmission device of car bottom, realize surmounting the scooter of motion.
Background technology
Present commercially available Kickboard Scooter mainly is that a the feet step on the ground by the people obtains behind the power need to pedal ground continually, and fall down easily, be not suitable for using in the room by inertia traveling.In the patent documentation of bulletin, patent ZL01222047.7 has disclosed with the ZL0220224.2 document and has utilized pedal to be connected kinematic link, orders about the scooter device of gear change transmission again.This installs by the gear cluster speed change, complex structure, and setting accuracy requires high.Patent 2005100217579.9 documents disclose and have utilized the interactive pulling of two pedal irreversible engine structure to order about the trailing wheel walking, and the scooter of energy self-return.This apparatus structure is also complicated, though realized the two pedal interaction, gravity-center-change in the driving process, the crowd of sense of equilibrium's difference is difficult to operation.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of two pedal to step on the scooter that the walking of pulling transmission device drive rear wheels also can realize the pedal self-return mutually, function with common scooter, can in limited room, space, use, child need not practise and can use safely, and the adult also can be used for body-building.
The purpose of this utility model is achieved through the following technical solutions: this car is the four-wheel structure, and the front vehicle wheel symmetry is installed on the front axle, and the length of front axle is less than the width of vehicle frame, and hind axle and rear wheel are installed in the vehicle frame rear portion.Handlebar is placed on the vehicle frame by antifriction-bearing box, and is connected with front wheel spindle and can controls direction.Two pedals can step forward about having on the vehicle frame, pedal one end is fixed on the vehicle frame, the pedal bottom is connected with connecting rod by tension spring, connecting rod one end is connected on the preceding imput shaft, the other end is the circular-arc tooth that pulls out, preceding imput shaft is installed between bottom of frame front axle and the back axle, and three ratchets are set on the preceding imput shaft, and the ratchet on both sides contacts with the moving tooth of connecting rod one end.Between two rear wheels ratchet is installed on the hind axle, this ratchet is connected by the ratchet in the middle of on chain and the preceding imput shaft.Ratchet and chain are formed the device that transmits the human body pedal power, the foot-operated power of human body is given the back ratchet by connecting rod, preceding ratchet and chain gear, drive and coexist the rear wheel walking on the hind axle of back ratchet, the tension spring of pedal bottom can make pedal automatically reset, reach both feet and step on the purpose that wooden handcart travels mutually, meet the rule of walking.
The utility model adopts chain gear to realize the motion that surmounts of rear wheel and front vehicle wheel in conjunction with ratchet device, simple in structure, can not influence dolly and advance because of stretcher pops up, two pedals are stepped on mutually, meet the rule of walking, and can increase the speed that dolly moves ahead, dolly has four-point supporting to be not easy to fall down, so safety simply to use.
Description of drawings
Below in conjunction with drawings and Examples the utility model structure is described further:
Fig. 1 steps on the structural representation of formula scooter mutually for the utility model both feet;
Fig. 2 steps on the upward view of formula scooter mutually for the utility model both feet.
The specific embodiment
With reference to Fig. 1, the utility model both feet are stepped on the formula scooter mutually, comprising: handlebar 1, front vehicle wheel 2, vehicle frame 3, rear wheel 4, two pedal 5, tension spring 6, connecting rod 7, ratchet 9,10,11,12, preceding imput shaft 13, chain 14, hind axle 15, wherein handlebar 1 is placed on the vehicle frame 4 by antifriction-bearing box (not shown) and is connected with front axle 8, as the front portion walking and the steering function of supported cart.Vehicle frame 4 upper foreparts leave two oblong openings, and correspondence is loaded onto the square pedal of two block lengths and can be stepped forward, and the pedal bottom is connected with connecting rod by tension spring, and on the imput shaft, the other end was the circular-arc tooth that pulls out before connecting rod one end was connected.Bottom of frame is installed back axle 15, and rear wheel 4 symmetries are installed in the same long back axle two ends with frame width.Imput shaft 13 before installing between front axle and the back axle, preceding imput shaft is provided with three ratchets 9,10,11, and the ratchet 9,11 on both sides contacts with the moving tooth of connecting rod one end respectively.Ratchet 12 is installed between two rear wheels on the hind axle, and this ratchet is connected by the ratchet 10 of centre on chain 14 and the preceding imput shaft.
As shown in Figure 2, under the mode of operation, depress pedal 5, tension spring 6 pressurizeds promote connecting rod 7, the circular-arc ratchet 9 that pulls out on the preceding imput shaft 13 of tooth (not shown) drive of connecting rod one end rotates, imput shaft 13 was rotated with middle ratchet 10 before ratchet 9 drove, and rotated by chain 14 driving pawls 12, back axle 15, trailing wheel 4, and trailing wheel rotates and drive dolly rapid movement.When left foot lifts right threading following time, spring pulling left side, left side connecting rod automatically resets left-hand tread plate, at this moment left side ratchet 9 revolutions on the preceding imput shaft, the ratchet 11 that the right side connecting rod is stirred the right side drives middle ratchet 10 rotations, the both sides ratchet is independent of each other, middle 10 on ratchet is done unidirectional rotation, meets the rule of walking, and can increase the speed that dolly moves ahead.
