Description

Roller shoes

The utility model relates to footwear, the wheel footwear that particularly a kind of individual of can be used for rides instead of walk.

The wheel footwear that existing individual wears as roller skate that the crowd was familiar with etc., can only supply a few peoples' physical culture, amusement usefulness, and the user need be trained; Again because the pin of walking out is " eight " font, wide, the poor stability of road occupying in travelling, climb and fall is dangerous; Even some modifieds wheel footwear need not slide, and routinely during walking, also can only be that wheel is stuck, capable, more awkward with wheel filial generation step, can not be used for ordinary person substantially and ride instead of walk.

The purpose of this utility model provides a kind of device of riding instead of walk for ordinary person, it is had wear conveniently, safe, simple in structure, characteristics that cost is low.

The purpose of this utility model is to realize by the wheel footwear that following design provides.This footwear of taking turns are made up of base plate and four rolling, it is characterized in that, front-wheel is contained on the front axle of bearing and ratchet, have installed a ratchet on the front axle, are provided with the front-wheel connecting rod at the axle two ends, and front-wheel connecting rod lower end is connected to the transducing spring; Installed rear spring on the hind axle, the axle two ends are trailing wheel connecting rods, and back wheel apparatus is on the trailing wheel connecting rod.The position block of band auxiliary spring is housed on the front-wheel link supports bar, and the trailing wheel base plate is provided with the trailing wheel lock pin; Also be provided with lifting lever, return spring and trailing wheel lock pin lever in front and back wheel; Base plate is made up of tiptoe board, noseplate, back base plate etc., and tiptoe board is connected with hinge with noseplate, and noseplate is connected by connecting plate with the back base plate, adjusts connecting plate, can regulate base plate length, and rubber cushion is housed under the noseplate, and the heel of belt glue pad is housed under the back base plate.

Accompanying drawing 1 is the utility model structural representation, also is one of embodiment.

Below in conjunction with accompanying drawing operation principle of the present utility model and structure are further specified.

When putting on wheel footwear walking, sole is executed rear riding force on the wheel sole, and roller contacts to earth and is subjected to ground reaction force and produces a trend of rolling in the direction of the clock, owing on the front-wheel 6 ratchet 7 is arranged, so do not rotate; Simultaneously because rear riding force and gravity effect, front-wheel connecting rod 16 will be clockwise rotated along pitman shaft 17, at this moment, trailing wheel will have a faint rolling backward, and transducing spring 9 is stretched, when pin stops firmly, when human body moves ahead, the pulling force of spring 9 is released, together with the reaction force acts of human body rear riding force on the roller of another leg, thereby make it quick rolling.The faint rolling backward of the stretching of transducing spring and trailing wheel, just like archery, string is tight more, and the arrow tail retreats more, and then the speed of arrow shooting is high more, and energy discharges big more.When needs stop to move ahead (during brake), people's heel presses down, and forefoot lifts, then trailing wheel connecting rod 15 is walked around the trailing wheel center line and is overcome the elastic force of rear spring 21, drive trailing wheel 29 and rotate rapidly and raise, heel 12 is contacted to earth, play braking action around trailing wheel pitman shaft 14.The size of brake force is subjected to the contact to earth influence of pressure of front-wheel, requires that anxious forefoot lifts, and makes front-wheel liftoff fully in a flash, and this moment, the brake force maximum when slow braking, can make front-wheel contact to earth, and grasped front-wheel pressure over the ground, can follow one's bent to play and slowly brake purpose.When stair activity or the difficult rolling of road conditions difference, can ground will be left on the front and back wheel, when footwear are walked.Method is as follows: (1) trailing wheel lifting: depress heel, trailing wheel is risen, press trailing wheel lifting lever 31 trailing wheels by on carry, liftoff and overcome the elastic force of rear spring 21, when trailing wheel lifting lever 31 is crossed trailing wheel lock pin 13,13 will stick lever automatically, make it and can not descend, trailing wheel is also just headed on and can not descend by lever simultaneously, and the trailing wheel lock pin is just like door lock, an inclined-plane is arranged, and shrinking back automatically after commentaries on classics is run on the connecting rod is stuck then.When the needs trailing wheel descends, press trailing wheel lock pin lever 33, then contract behind the lock pin 13, trailing wheel is returned to original position under spring 21 effects, see accompanying drawing 2.(2) front-wheel lifting: press front-wheel connecting rod block 25, reality also is a lock pin, loosens the pressure of sole to base plate, and then front-wheel connecting rod 16 rotates counterclockwise around pitman shaft 17, and the principle that leaves ground in the continuation is also seen accompanying drawing 2 with the trailing wheel lifting.The front and back wheel range of movement is subjected to each stop limits, and can regulate in certain limit.Wheel sole length can change by the lock-screw position of adjusting connecting plate 23.The tiptoe base plate adopts hinge to be connected with noseplate, when footwear wear, makes the sole place be convenient to bending, adapts to the human locomotion posture.

The utility model has the advantages that: when 1, taking full advantage of human locomotion, the potential energy that produces during center of gravity moves up and down is by transducing spring 9, be converted into the power that moves ahead, so that walking speed improves, its speed can reach more than 20 kilometers/hour, and is close with bicycle. Simultaneously, spring 9 also has cushioning effect, and to reduce body shake, when human body imposes rear riding force, noseplate will be little shape that has a down dip, and the posture of exerting oneself of pin is identical during with people's walking, is convenient to the application of force. 2, brake reliably makes things convenient for, and sliding trajectory is consistent with people's walking direction, is suitable for the individual and makes safe walking-replacing tool. 3, easy to use because front and back wheel can in seconds realize receipts, can be as city shoe walking stair activity or duck into the store shopping and needn't take off. 4, simple in structure, volume is little, in light weight, cost is low, it is easy to maintenance to carry. In view of above advantage, if the epicycle footwear are promoted the use of, to alleviate the urban traffic pressure, solve the problems such as bicycle is crowded, parking difficulty, for the cities and towns teenager go to school, people's short distance is gone out, (as weave cotton cloth, cotton mill) workman's dealing operation, restaurant bar service, out on tours visit etc. all can be applied between large car. The high-leveled and difficult technical movements of begining to learn the roller skate of roller skate person's quick grasp also are one well help as using earlier this to take turns footwear.
