Abstract
The utility model relates to a lifting shoe which wheels can be folded towards to sole, which is characterized in that the shoe body between front and back wheels is provided with a transmission cable between. Via human gravity, the corner between a lever supporting the front and back wheels and the shoe body is reduced, while one end of the lever via the transmission cable drives front and back cranks to rotate parallel with the bottom plate and via the cable rotates the back wheels. The utility model has simple structure, while main transmission portion is arranged in shoe body, to avoid clamping foreign materials.
Description
One, technical field:
The utility model relates to lift that a kind of footwear wheel can draw in to sole direction footwear voluntarily, belongs to International Classification of Patents A43B or A63C17/00.
Two, background technology:
At present, the footwear of belt wheel commonly used have roller skate, and its wheel is fixed on the shelf of sole, lean on people's thrust to make its motion.Someone has invented footwear formula Rider propulsion wheeled vehicle, as 91230835.4 utility model patents, it is made up of the footwear body that has scroll wheel, uni-drive gear box, column tooth bar, the stops of stopping, and utilize the column tooth bar to link together with the footwear body and the uni-drive gear box of scroll wheel, adopt gear train to carry out transmission and speedup, and reach the purpose that human body potential energy is converted into kinetic energy.Its shortcoming is: device is heavy, and inconvenience is carried and used, the easy lined trousers pin of double-decker and other foreign matter, and dangerous, the gear drive kinetic equation loss is many, and noise is big.
Three, summary of the invention:
The purpose of this utility model be to provide a kind of simple in structure, by the lift of strap transmission footwear voluntarily.
The technical solution of the utility model is: have footwear body, front-wheel and trailing wheel, it is characterized in that: be provided with two curved bars before and after on the footwear body above front-wheel and the trailing wheel; Front-wheel is connected by the bearing block of support lever with footwear body base plate front portion; One end of support lever is arranged on the front-wheel wheel shaft, and the middle part is arranged on the bearing block axle, and the other end is connected with an end of curved bar by stay cord; Trailing wheel is connected by the bearing block of hollow support rails with footwear body base plate rear portion; One end of hollow support rails is connected with rear axle; The middle part is arranged on the bearing block axle, and the other end is connected by the end of stay cord with the back curved bar; Be provided with strap in the footwear body between the front-wheel trailing wheel, one of strap is fixed on the bearing pin of footwear body front portion, the other end is passed hollow support rails and is twined and be fixed on the ratchet sleeve of hind axle, and strap is by being arranged on slide bar in the footwear body and the pulley on two curved bars of front and back with its tensioning.
The utility model in use, when people's foot-operated following time, under the effect of body weight for humans power, supporting the support bar of front and back wheel and the angle of footwear body diminishes, two curved bars did to be parallel to the motion of sole before and after one end of support bar drove by strap, the end of curved bar is equipped with pulley, can spur strap and the ratchet sleeve that drives on the hind axle by strap rotates, thereby trailing wheel is rotated.When carrying pin, the spring that circles round drives the ratchet sleeve revolution, make strap be wrapped on the ratchet sleeve again again, and the front and back curved bar is got back to original position when strap tightens up, the angle of front and back wheel support bar and sole also returns to original state, so circulate repeatedly, thereby change human body potential energy into kinetic energy, reach purpose voluntarily.

The specific embodiment:
The utility model is made of footwear body 4, front-wheel 1 and trailing wheel 11, be fixed with former and later two bearing blocks on the bottom surface of footwear body, front-wheel is fixed on the bearing block of front by the middle part of support lever 2, and preceding curved bar 5 is fixed in the footwear body of front axle bearing top from crank throw by axle.Support lever is the steel body of a meander-like, and an end of supporting lever is connected with front axle, and the other end links to each other by the end of the preceding curved bar 5 in stay cord 6 and the footwear body.Trailing wheel is fixed on the bearing block of back by hollow bar 10, and back curved bar 9 is fixed in the footwear body on hind axle bearing top from crank throw by axle.One end of hollow bar is connected with trailing wheel, and the other end is connected by an end of the back curved bar 9 in stay cord and the footwear body.Ratchet 12 is installed on hind axle, between front and back two curved bars in the footwear body, is fixed with many slide-bars 7, be provided with steady pin 19 in a go forward side of curved bar of footwear body.One end of strap 8 is fixed on the steady pin, and the other end passes in the hollow bar of trailing wheel, twines several circles and is fixed on the ratchet sleeve 12 on the hind axle.Strap is by the pulley on the two curved bar ends of front and back and be fixed on many slide-bars on the footwear body with its tensioning.When the people sets foot on the footwear body, can force front and back wheel toward interior gathering, curved bar rotated before and after the front and back wheel support lever made by stay cord, and made the strap pulling and the ratchet on the hind axle is rotated by the pulley on the curved bar end of front and back, even also trailing wheel rotates.When carrying pin, main spring 20 drives the ratchet sleeve revolution, and strap is wrapped on the ratchet sleeve again, and the front and back curved bar is returned to original position again when strap tightens up, and the angle of front and back wheel lever and base plate also restores to the original state, so repeatedly.
For the ease of stair activity and easy to carry, the utility model has also designed stop device, its stop device is formed by hitting button 3, stop rope 16, arresting lever 17, latch 18 and scotch 13, hit button and be arranged on the front of footwear body, hitting button is connected with an end of stop rope by arresting lever, the other end connection of stop rope is arranged on the scotch at footwear body rear portion, and is fixed on the footwear body, and the arresting lever on the stop rope connects Stop-motion lock.Stop-motion lock is arranged on the next door of front and back wheel support lever.When bump hits button, under the effect of arresting lever 17, the tension of stop rope, arresting lever promotes, Stop-motion lock 19 makes it block extension on the front and back wheel support lever, makes not return of front and back wheel, and is in rounding state, at this moment, 13 of scotch block trailing wheel and do not allow its rotation, but facilitating going upstairs and going downstairs so just, when hitting button once more, under spring action, each several part can be got back to original position.
The utility model is provided with brake arm 14 and the piece 15 of only stopping at the afterbody of footwear body.
