Description

Foot-operated speeder

A kind of foot-operated speeder can be used as a kind of walking-replacing tool and uses, and also can be widely used in people's places such as excursion, body-building recreation and contest.

At present, existing foot-operated driving walking-replacing tool roughly divides two classes, one class is to be the wheeled mechanism of typical case's representative with the bicycle, their running part generally is made up of sprocket wheel, chain structure, by the engagement speedup transmission between large and small sprocket wheel and the chain, the moment that produces when foot-operated is delivered on the large diameter driving wheel, drives whole vehicle movement, this walking-replacing tool has become the popular vehicles that generally use because it is easy to use, quick, improve greatly than walking speed.But the walking-replacing tool of this class carries as if getting on or off the bus with oneself or need be interrupted on the road when using, and will lose possibility because of its volume problem; Another kind of is to be the instrument that slides that has roller of representative with slide plate, roller skate that present young people uses always, they mainly are made of frame and the roller that is located under the frame, this walking-replacing tool is because it is simple in structure, be easy to carry, be usually used in the public place of entertainment, also have human to slide, but owing to wherein power transmission and accelerator be not set in short distance, from and exist and have certain requirement, power hour can't start and speed waits deficiency more slowly user's degree of exerting oneself.

The purpose of this utility model is to provide a kind of foot-operated speeder, and it both can utilize pedal power to carry out effective speedup and slide, and is simple in structure again, be convenient to carry, and uses laborsaving, convenient.

For achieving the above object, the utility model adopts following structure, it comprises the supporter which is provided with driving rolls and return idler, the pedal that is located on the supporter and is hinged and connected with supporter, and be located at moment between pedal and the driving rolls, in the time of will treadling and be delivered on the driving rolls and produce the mechanical speed increasing mechanism of speedup effect, ratchet is installed in the driving rolls, and the output of mechanical speed increasing mechanism is connected with the rotating shaft that ratchet and driving rolls are installed.

Operation principle of the present utility model is as follows: it adopts foot-operated the driving, by mechanical speed increasing mechanism speedup, and roll to drive the working method of whole device motion by roller, during use, whole device is placed on the ground (or supporting surface), driving rolls and return idler contact with ground (or supporting surface), single pin of user or both feet stand on the device instead of walk, by foot with can contact along certain axis pedal that to be the center rotate around supporter, like this, treadle, the speedup power transmission of the mechanical speed increasing mechanism between pedal and driving rolls, just can the moment when treadling at first be delivered in the rotating shaft of fixed ratchet wheel, pass to driving rolls through ratchet again, drive return idler by driving rolls, whole device reaches the user of carrying thereon, and (or supporting surface) slides along ground together.The ratchet transferring power is installed in driving rolls, can makes the driving rolls single load bearing, when treadling, transmit moment of torsion, do not do work when pedal lifts or when not scrunching, only play the rolling bearing effect, to guarantee that device instead of walk slides glibly.

Mechanical speed increasing mechanism described in the utility model can be that the gear up transmission mechanism of feature constitutes with the tooth that intermeshes by one group, the arc-shaped rack that it comprises and pedal is fixedly linked and be located at arc-shaped rack and driving rolls between gear train, realize the speedup drive task by the engagement between tooth bar, gear and gear, terminal gear in the gear train and ratchet are fixed in the same rotating shaft, by ratchet the output of gear train are passed to driving rolls.

Mechanical speed increasing mechanism described in the utility model also can adopt one can produce connecting rod, slide block and tooth bar, the gear combination mechanism of speedup effect, it comprises the connecting rod that is hinged and connected with pedal, spacing sleeve is carried out in link motion, by a wedge shape or arc contact surface and but interlinking lever end keeps in touch, and the slide block that moves of along continuous straight runs, the horizontal rack that slide block is provided with, the gear that is meshed with tooth bar, and slide block moved horizontally the guide rail that leads and guarantee the accessories such as back-moving spring of slide block reliable reset.During work, stepping of pedal changed into the horizontal movement of slide block by the slip of the contact between connecting rod, slide block, engaged transmission through between horizontal rack that slide block is provided with and the gear that is meshed with it converts the horizontal movement of slide block to the rotation of gear again, gear and ratchet are fixed in the same rotating shaft, carry out power output by gear.

Also be provided with spring between the rear portion of pedal described in the utility model and the supporter and keep linking to each other, utilize the pulling force of spring, open reliably with the assurance pedal.

The utility model owing to adopt will be ridden the integrated design structure that driving, mechanical speedup, coasting mechanism compactness combine, thereby not only overcome and generally slided the effectively shortcoming of speedup of class device instead of walk, improved simultaneously sliding speed greatly in the labour-saving, and compare with the wheeled mechanism that carries out speedup by chain, chain sprocket structure, its volume reduces greatly, easy to use, and be convenient to carry.

Below in conjunction with drawings and Examples the utility model is described in further details.
