Abstract

The utility model relates to a novel amusing body-building cycle for children, which combines body-building and amusement into one body, and comprises a cycle body (a main girder) 1, a cycle seat 2, a front shaft 3, a front wheel 4, a control rod 5, a connecting rod 6, a back swing shaft 7, a back wheel 8, a handle 9, screw bolts 10, a slide way 11, a rotating shaft 12, adjusting pins 13, etc. A double-swing rod mechanism (a driving mechanism) is composed of the cycle body 1, the control rod 5, the connecting rod 6 and the back swing shaft 7. The utility model protrudes the novelty and the function of the amusing body-building.

Description

The interesting body-building carriage for children

The utility model relates to a kind of carriage for children of novelty, is that collection body-building and amusement are the interesting body-building carriage for children of one.Belong to the small stores technical field.

Present carriage for children has multiple, and existing it is by vehicle body with regard to foot-operated three-wheel carriage for children, vehicle seat, and front and back wheel and pedal are formed.Have amusement, body-building function simultaneously.But change is little in decades, and action is dull, and body-building effect is poor.

The purpose of this utility model is to doing bigger improvement when the consistent foot-operated three-wheel carriage for children of previous decades, strengthening its interest and health care.Make children in Entertainment, mould mood, take exercises, keep physically and mentally healthy.

The utility model is achieved in that

The interesting body-building carriage for children comprises vehicle body (girder) 1, compositions such as vehicle seat 2, front axle 3, front-wheel 4, joystick 5, connecting rod 6, back balance staff 7, trailing wheel 8, handle 9, bolt 10, slideway 11, rotating shaft 12 and adjusting pin 13.

Fig. 1 is an interesting body-building carriage for children front view;

Fig. 2 is an interesting body-building carriage for children birds-eye view.

Below in conjunction with accompanying drawing the utility model is described further:

Vehicle body 1 is a girder, plays a part to connect, support miscellaneous part, has certain intensity and rigidity, to guarantee the safety of carriage for children.Vehicle seat 2 is connected on the vehicle body 1 by bolt 10.Front-wheel 4 and trailing wheel 8 are installed in respectively on front axle 3 and the back balance staff 7, and front and back wheel can freely be rotated on axle.Rotating shaft 12 is cemented on the front axle 3, and front axle 3 can be rotated with respect to vehicle body 1.

Vehicle body 1, joystick 5, connecting rod 6 and back balance staff 7 are formed a double-lever mechanism, also claim driver train.The people is sitting on the vehicle seat 2, and both feet are pedaled on front axle 3, and both hands are held the handle 9 of joystick 5 upper ends and rowed the boat similarly, and leg is pedaled forward, leans back, and upper limbs pulls back joystick 5.-----double-lever mechanism principle according to four-bar mechanism, connecting rod will drive back balance staff 7 relative vehicle body 1 counter-clockwise swings.This moment, the people had an action of carrying stern, made the pressure relieve of back balance staff 7, and leg and pin increase the pressure of front axle 3 when carrying stern, so front-wheel 4 is motionless with basic fixed, vehicle body is also motionless.Trailing wheel 8 rolls forward.This stage has been finished the preceding half trip of motion.

Upper part of human body leans forward afterwards, and upper limbs promotes joystick 5 and swing forward, drives afterwards balance staffs 7 by connecting rod 6 and swings after with respect to vehicle body 1 clockwise direction.Therefore because this moment, people's thigh was in instantaneous relaxed state, the pressure effect of people's whole body mainly concentrates on the car rear portion, and this moment, trailing wheel 8 was motionless substantially, had only front-wheel 4 to roll forward, and the drive vehicle body moves forward together, finishes the back half trip of motion.

Said process constantly repeats, and dolly just can advance in trailing wheel, front-wheel are intermittently replaced the process of motion.

In Fig. 2 birds-eye view, the people is when driving dolly, and both feet are pedaled in the both sides of front axle 3, if bipod firmly varies in size, front axle 3 are rotated relative to vehicle body 1 by rotating shaft 12.Thereby change the dolly working direction.

Vehicle seat 2 is fixed on the vehicle body 1 by bolt 10.Bolt 10 is unclamped, by slideway 11 vehicle seats 2 relatively vehicle body 1 move forward and backward adjusting within the specific limits, with adapt to different height, make take more comfortable.

In Fig. 2 driver train, adjusting pin 13 is the hinges that are connected of joystick 5 and connecting rod 6.When adjusting pin 13 is articulated in I, II on the joystick 5, III hole respectively with connecting rod 6, be equivalent to change the length of the fork OA on the double rocker mechanism driving lever 5.Also just adjust people's upper limbs and pulled the size that joystick 5 is exerted oneself.Control people's exercise dynamics with this.

In sum, the utility model is compared with the foot-operated children tricycle of tradition, has given prominence to novelty, the body-building practicality. Vehicle body Movement be by double rocker mechanism control, make front and rear wheel one stop one and movingly intermittently roll, very novel because rear balance staff 7 is past Physical pendulum is moving, makes the rear portion of vehicle body 1 one on the other, and sensation is horseback arranged, and has increased children's interest. And similar row the boat Action needs again upper and lower limb, and waist is exerted oneself jointly, cooperation, thus reach the motion whole body, constitutional purpose. Simultaneously also train children's brain response speed and coordinative command ability, be conducive to again the exploitation of children's intelligence.
