Further specify below in conjunction with the operation principle and the structure of accompanying drawing the wheel footwear.

When putting on the walking of wheel footwear, sole is executed rear riding force on base plate, roller contacts to earth and is subjected to ground reaction force and produces the trend that clockwise direction rolls, and under the ratchet mechanism effect, front-wheel does not rotate, this moment, trailing wheel had one to roll slightly backward, transducing spring 14 is stretched, and when pedaling human body moving ahead after pin stops firmly, the elastic force of spring 14,3 is released, act on the roller of another leg, thereby make it quick rolling.When needs stop to move ahead (brake), with heel 21 press down, forefoot lifts, then back link 27 is the center with axle 28, overcome the elastic force of return spring 37, walk around back link axle vertical center line AB and clockwise rotate, drive trailing wheel 26 rotates rapidly and raises, and heel is contacted to earth realize braking.The size of brake force is subjected to the front-wheel pressure influence of contacting to earth, and anxious half sole lifts in a flash, and front-wheel is liftoff; Delay in a flash, front-wheel is still contacted to earth, grasp front-wheel pressure over the ground, can follow one's bent reaches the slow purpose of stopping.In the time need not braking, the half sole application of force is lifted heel, and trailing wheel promptly under return spring 37 effects, goes to the state of contacting to earth rapidly, continues to move ahead.In the time of need surmounting forefathers in advancing, tiptoe presses down and makes the footwear bell step on button 1 rolling of contacting to earth, and can send signal by connecting in the wire pulling footwear bell 5 that protects nose 32.During the unsuitable rolling of stair activity or road conditions difference, can walk when footwear on the front and back wheel, its operation is as follows: 1) trailing wheel rising with leaving.Lift on the forefoot and make trailing wheel be braking state, heel contacts to earth, lifting trailing wheel lift lever 16 again makes connecting rod 27 continue to go up the elastic force that commentaries on classics overcomes spring 37, (detent configuration is just like door lock when crossing trailing wheel lock pin 17, an inclined-plane is arranged), connecting rod is stuck, and finishes trailing wheel and rises, then lever 16 homing again; Want trailing wheel to descend, press and contract after trailing wheel lock pin 17 makes it, trailing wheel promptly resets rapidly under spring 37 effects and contacts to earth.2) front-wheel lifting.Press and contract after front-wheel lock pin 10 makes it, then connecting rod 7 rotates counterclockwise around axle 6 under spring 14 initial tensile force effects, thereby driving front-wheel 2 rises, the inertia that front-wheel rises makes connecting rod 7 touch lock pin 8, contract after making the lock pin inclined-plane, connecting rod 7 continues upward to change when crossing lock pin to be stuck, and finishes on the front-wheel and changes, and this process is very rapid and very brief.Spring 14 still hauls connecting rod 7 lower ends at this moment and presents oblique shape and certain pulling force is arranged, and is just big less than initial tensile force.When needing front-wheel to descend, contract after only need making it by pendulum lock pin 8, and to utilize the front-wheel decline lever (its structure is identical with the trailing wheel lift lever) be contained on the pitman shaft 6 to make connecting rod 7 be that the center clockwise rotates with axle 6, bump the inclined-plane of the pin 10 of unblanking with the pulling force that overcomes spring 14, connecting rod 7 is stuck, and front-wheel returns to the state of contacting to earth.By pendulum lock pin 8 with utilize front-wheel decline lever, making the front rod rotating process can be a linkage process.When footwear walk or during rolling the footwear bell step on button and also need to change or change certain angle down do not move ahead so that do not influence, its operating principle is also identical with the roller lifting, utilizes lock pin and lever to realize.

Advantage of the present invention is: 1, center of gravity moves up and down the potential energy of generation when taking full advantage of human locomotion, be converted into the power that moves ahead by the transducing spring, so that walking speed improves, its speed can be close with bicycle, this transducing spring also has cushioning effect simultaneously, 2, brake reliably makes things convenient for, people's center of gravity descends during brake, more complete, 3, running orbit is consistent during with people's walking with application of force direction, floor space is little in advancing, 4, be provided with and surmount the footwear bell recoil simulator that moves ahead, can in time remind the other side, 5) easy to operate, front and back wheel and step on button and all can about 5 seconds, all realize receiving or descend, so stair activity, the shopping of ducking into the store can be taken off, because tiptoe board becomes to be flexibly connected with noseplate, can curvedly bend again, so when footwear wear, do not feel awkward, 6, simple in structure, volume is little, weight is light, cost is low, easy to carry. If therefore the epicycle footwear are promoted the use of, to reduce the urban traffic pressure, the solution bicycle is crowded, the bicycle parking difficulty, remove the problem such as go downstairs on the car, the teenager goes to school to cities and towns, and people's short distance is gone out, (as weave cotton cloth, cotton mill) workman's dealing operation between large car, restaurant bar service, out on tours visit etc. all can bring convenience. Simultaneously also can be used as the body-building recreation articles for use, wear earlier the epicycle footwear if begin to learn roller skate person, will be one to quick grasp roller skate technical movements and well help.
