Abstract

The utility model relates to a light children cycle. An operating rod of the cycle is connected with a rear wheel bracket. A front wheel bracket is connected with a seat cushion through a front fork rod. The joint of the operating rod and the front fork rod is provided with a moving hinge. A crankshaft-connecting rod mechanism is hinged with a transverse rod under the front fork rod; the front and the back sides of the crankshaft-connecting rod mechanism are respectively provided with wheels with a diameter of about 30CM. The utility model is characterized in that the operating rod is hinged with the transverse rod by a spring, and the seat cushion is regulated by a telescopic rod. The utility model solves bodily injury to children caused by oversized operating force of the original children cycle, so that the children can more easily operate the children cycle.

Description

The hand-held design body building bicycle for children

The utility model is a kind of through laborsaving, the comfortable toy body building bicycle for children of improved novelty.

As everyone knows, the joystick of body building bicycle for children links to each other with the support of trailing wheel, and front-wheel then links to each other with seat cushion by the front fork stem that is equipped with tread plate.At joystick and front-wheel fork arm intersection mobilizable hinge is arranged.Respectively there is the plastic wheel of about 30 centimetres of two diameters front and back.When children ride over when with the hands holding joystick on the body building bicycle for children and firmly pulling back, front-wheel rolls by a small margin, and trailing wheel then rolls significantly.Simultaneously, the rising of joystick has also driven the rising that connects front-wheel fork arm other end seat cushion, and the people is upwards risen.When joystick pushed away forward, the trailing wheel that links to each other with crankshaft-connecting rod mechanism then rolled by a small margin, and front-wheel then rolls forward significantly.Simultaneously, the people also descends along with the decline of seat cushion.When children constantly pull control lever, riding over top people also can be along with the preceding and then continuous heave and set of car.As everybody knows, the motion of this body building bicycle for children is to order about connecting rod by joystick to drive bent axle and make it to produce a parallelogram that is similar to a distortion and just make car proal.Therefore, before bent axle arrives during stop, joystick and seat cushion are in bottom dead point separately, return the back stop at bent axle, just joystick and seat cushion turn back in this one stroke of original top dead point, must by car forward with the inertia of health up-and-down movement, firmly spur joystick and just can turn back to original state, degree firmly certainly will be strengthened like this, just this purpose can be reached.Because children's muscle is not physically well developed as yet, can increase possibility of children's on the go pulled muscle like this, the loss that the while is also too much children's muscle power, healthy unfavorable to children.Also have because seat cushion is fixed on the front fork stem back, can not adapt to the children of various heights and body weight.Joystick also since be one vertical, can not make children's on the go reach comfortable degree equally.At above problem, common way is to make hinge move certain distance in design behind front fork stem, or makes seat cushion move forward certain distance, but still can not obviously improve above-mentioned defective.

The purpose of this utility model provides the laborsaving and comfortable body building bicycle for children of a kind of adjustable novelty.

The utility model is achieved in that at joystick and is connected on the cross bar of connecting rod mechanism with front fork stem, designs a spring.Be appreciated that original starting state of the present utility model is just opposite with original design starting state.When children ride on the body building bicycle for children, the weight of self can make seat cushion descend, and the horizontal type joystick pushes away forward, and front-wheel rolls forward significantly, trailing wheel then rolls by a small margin, when bent axle turned back to the back stop by preceding stop, spring elongation by compression promoted joystick and rises, cross bar pushing drawing rod mechanism, trailing wheel then rolls forward significantly, and front-wheel then rolls by a small margin, and the motion of car has also driven the rising of seat cushion.Constantly promote joystick this moment, rides over top people and just also rising and falling and travel forward.Since spring balancing the impulsive force in the motion, add adjustable seat cushion, make that control body building bicycle for children becomes easy.

The utility model is owing to designed and can pull the spring of power by balance control, with device that seat cushion is freely stretched and horizontal type joystick, thereby can make children more laborsaving and comfortable when controlling body building bicycle for children, reduce the unfavorable factor to health that may cause with excessive loss's muscle power of pulled muscle.

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

Fig. 1 is the utility model incipient state figure.

Fig. 2 is the constitution diagram of the utility model bent axle to preceding stop.

Describe concrete device and the details that the utility model proposes in detail below in conjunction with Fig. 1, Fig. 2.

The support (11) of joystick of this body building bicycle for children (5) and trailing wheel (2) links to each other.The front-wheel support (12) that is equipped with tread plate (4) then links to each other with front fork stem (3), and a seat cushion (7) is settled in the other end of front fork stem (3).There is hinges (6) joystick (5) and front fork stem (3) intersection.In the design of the place of joystick (5) and cross bar (8) one spring (14) is arranged.Be appreciated that starting state of the present utility model is just opposite with original starting state.When children ride on the body building bicycle for children, the weight of self can make seat cushion (7) descend, and pushes away before the joystick (5) that spring (14) pressurized is shortened, and front-wheel (11) rolls forward significantly, and trailing wheel (2) then rolls by a small margin.When bent axle (10) turns back to the back stop by preceding stop, spring by compression (14) extends again, promotes joystick (5) and rises, cross bar (8) pulling connecting rod (9) mechanism, drive and sail bent axle (10) drive trailing wheel (2) rolling forward significantly, front-wheel (1) then rolls by a small margin.Simultaneously, front fork stem (3) drives seat cushion (7) and makes upwards rise of people.Constantly promote joystick (5) this moment, rides over top children and just also rising and falling along with the motion of car and advance.Since spring (14) balance the power of pulling of joystick (5), and more easily stressed horizontal type joystick (5) makes children more laborsaving when controlling body building bicycle for children, more comfortable.Easier for the adjustment that makes seat cushion (7), reach flexible purpose in the iron pipe of expansion link (13) the insertion front fork stem (3) that the utility model employing links to each other with seat cushion.

Claims (3)

1 hand-held design body building bicycle for children, the joystick of this car links to each other with the support of trailing wheel, the front-wheel support that is mounted with tread plate then links to each other with seat cushion by front fork stem, there is mobilizable hinge to be connected in joystick and front fork stem intersection, crankshaft-connecting rod mechanism then with front fork stem on cross bar hinged, the wheel of about 30 centimetres of diameters is respectively arranged in front-wheel support and rear wheel support both sides, and it is characterized in that: joystick is hinged by spring and cross bar.

2 hand-held design body building bicycle for children according to claim 1, it is characterized in that: seat cushion and front fork stem are combined by telescopic expansion link.

3 hand-held design body building bicycle for children according to claim 1 is characterized in that: joystick is the pressure-bearing type joystick.
