Abstract

The invention discloses one-way roller blades. In a main structure, a front wheel is a one-way wheel and is fixed to the front end of each support by using a shaft and a support boundary parapet; a rear wheel is a two-way wheel, and is fixed to the rear end of each support only by using the shaft; the front wheel is formed by a rubber outer sleeve, an iron outer sleeve, a core, a core boundary parapet and a bearing; the rubber outer sleeve is welded outside the iron outer sleeve; internal teeth are arranged in the iron outer sleeve and are in sliding fit with the core; notches are formed on upper and lower sides of the core; a jack capable of moving up and down is arranged in each of the notches; the jacks are in contact fit with drawing wires fixed in the core notches; the core is compatible with the shaft by using the core boundary parapet; and the shaft is compatible with the supports on both sides by using the support boundary parapet. In the one-way roller blades, the front wheels rotate forwards only but cannot rotate backwards, so people wear the one-way roller blades and kick backwards alternately to move ahead. The one-way roller blades have high power and speed, meet the walking habit of human bodies, and are suitable for doing physical exercise.

Description

Unidirectional roller skate

Technical field

The present invention relates to a kind of roller skate, refer in particular to a kind of front-wheel and can only roll forward, can not roll backward, pedal the unidirectional roller skate that just can move ahead after being through on two pin alternately.

Background technology

At present, sell the roller skate of sliding before and after can be on hardened ground on the market, also be roller skate.Its structure is that a plurality of wheels are installed under the sole, and wheel can be divided into single and double two kinds.But and the wheel of these roller skate all former and later two directions rotate, its power that advances is to be pedaled laterally by a pin to step on ground and forms reaction force, promotion another pin is carried a load on the back human body forward.This progression is identical with the mechanics principle of skating, and its shortcoming can only side be pedaled exactly, can not after pedal, reaction force direction and direction of advance be 90 the degree angles, not only thrust is little, speed is slow, and vacillates now to the left, now to the right, it is also wide to account for the road surface.So existing roller skate can only be taken exercises as a kind of athletic sports appliance ground on the scene, use and be not suitable as the vehicles.Develop a kind ofly, replace the roller skate front-wheel of above-mentioned bidirectional rolling, form and pedal the unidirectional roller skate that front-wheel can move ahead after a kind of and accord with the demands of the market with the unidirectional wheel that rolls forward.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of roller skate, and the front-wheel of this roller skate can only roll forward, can not roll backward, just pedals and can move ahead after being through on two pin alternately.

The technical problem to be solved in the present invention is realized by following scheme: unidirectional roller skate, comprise lace loop, support, set bolt, axle and wheel, use the set bolt fixed support below the lace loop, use fixedly wheel of axle in the support, it is characterized in that: described wheel is divided into two of front and back, front-wheel is unidirectional wheel, be fixed on the support front end with axle and support circle increase, trailing wheel is two-way wheel, only be fixed on back-end support with axle, described front-wheel is by rubber sleeve, the iron overcoat, fuse, fuse circle increase and bearing constitute, the outer seam rubber sleeve of iron overcoat, internal tooth is set in the iron overcoat and is slidingly matched with fuse, notch is established in the both sides up and down of fuse, respectively adorn in the notch one movable up and down very heavy, very heavyly contact cooperation with the Pick Wire that is fixed in the fuse notch, fuse agrees with fuse circle increase with axle, and axle agrees with support circle increase with the support of both sides.

Operation principle of the present invention: when front-wheel rotates forward, the internal tooth of iron overcoat turns to consistent with very heavy perk direction, very heavy and Pick Wire is forced down in the fuse notch from back by teeth of internal tooth, these teeth turn over, and are very heavyly upspring by Pick Wire again, and next teeth is forced down very heavy and Pick Wire in the fuse notch from back again, so repeatedly, the relative fuse of internal tooth slides, and front-wheel can rotate forward, and human body moves ahead; And when after pedal front-wheel, when promptly front-wheel rotated backward, it is relative with very heavy perk direction that the internal tooth of iron overcoat turns to, both contain mutually, the iron overcoat just can not rotate backward.Like this, ground reaction force just can pass to the front and rear wheel of another pin by rubber sleeve, iron overcoat, fuse, fuse circle increase, axle, support circle increase, support, footwear, human body, and the people just can move ahead.

Advantage of the present invention is:

1, powerful, startup is fast, speed is also very fast.The mechanics principle of unidirectional roller skate and roller skate all is to be transformed into rotatory force pedaling the reaction force (being translation power) of stepping on ground, but common roller skate is that to the left and right translation power is transformed into forward rotatory force, the direction difference of two kinds of power become 90 degree angles, thereby transformation efficiency is not high; And unidirectional roller skate is that forward translation power (being ground reaction force) is transformed into rotatory force, the direction unanimity of two power, so the conversion ratio height, powerful starts soon, and speed is also fast.

2, it is long-pending little to account for the road surface, is suitable for the traffic practicality.This unidirectional roller skate is different with the mechanics principle of common roller skate, and common roller skate is the side direction power taking, so the amplitude of vacillating now to the left, now to the right is bigger, it is long-pending big to account for the road surface, is not suitable for the traffic practicality; And unidirectional roller skate is vertical power taking, so the amplitude of vacillating now to the left, now to the right is less, it is long-pending little to account for the road surface, is suitable for the traffic practicality.

3, the automatic sounding of energy, caution passerby.This unidirectional roller skate is when moving ahead, and each internal tooth of preceding strake overcoat all will slide on fuse very heavy, when interior tooth top slides into very heavy top, Pick Wire is pressed minimumly, again a little to more advancing slip, very heavy be bound to by Pick Wire on the tooth root, send the sound of " clatter clatter ".Wheel turns is fast more, and the speed that internal tooth slides on very heavy is fast more, and " clatter clatter " sound that sends is also rapid more, so just can allow passerby's vigilance and determine the variation of distance each other, thereby warns passerby.

4, volume is little, saves goods and materials and parking space.Though unidirectional roller skate is footwear, what mainly play is the effect of car.If take it with bicycle, automobile etc. relatively, it is the car of world volume minimum, so save goods and materials and parking space most, and can realize carrying and preventing loss.

5, unidirectional roller skate is without fuel oil, and comparing with motor vehicle is the vehicles of energy-conserving and environment-protective.

6, meet the human body walking custom, be suitable for taking exercises.Pedal power taking after the unidirectional roller skate, compare, more meet the custom of human body walking, thereby be suitable for most taking exercises with common roller skate, skating boots and bicycle.
