Abstract

Roller skates with driving mechanisms consist of a left roller skate and a right roller skate which have symmetrical structures; each roller skate comprises a base, a front-rear wheel part, a drive part and a brake part; the drive part consists of a lever, a pedal, a chain, a chain spring and a drive chain wheel; the lever are connected with the pedal on the lever through a sliding bush; the chain is connected with the lever, an auxiliary chain wheel and a drive chain wheel; the brake part consists of a brake pedal lever, a pedal lever spring, a friction plate, a disc spring and a bearing. With a lever principle, the utility model transforms one part of gravity of human body into a forward drive, thereby being laborsaving and fast in walking; the utility model has a reliable brake device and good safety and can replace a bicycle and used as vehicle or a recreational sport for young people.

Description

Footwear voluntarily

The utility model relates to motorless manned automatic carriage, we are called footwear voluntarily to it.

Bicycle is widely used at present, but volume still is excessive, and slide plate, roller skate also often are subjected to liking of teenagers, as a kind of amusement article, but level and smooth to site requirements, can not go on a long journey, its weak point is all arranged.

The purpose of this utility model provides a kind of part and replaces the personal traffic of bicycle and roller skate and motion to go up tool, on common urban road, put on voluntarily footwear after, by normal walking action, it is like flying just to hurry up.

These footwear voluntarily, by about symmetrical configuration two form, whenever include only pedestal, front and back wheel part, drive part and brake portion, it is characterized in that:

One, pedestal front and back wheel part: pedestal is made up of a stripe board and foot piece, is equipped with 1～5 road wheel below the stripe board front end, is equipped with power wheel below the rear end, and the foot piece end is equipped with auxiliary sprocket wheel;

Two, drive part: by lever, pedal, chain and drive sprocket are formed, lever is the metallic rod of one or two section broken line shape, hinged at the break place by pin and stripe board afterbody, pedal is arranged above the lever, connect by sliding sleeve between them, be fixed with shoestring above the pedal, on the axle of power wheel, be equipped with drive sprocket, it is a sub-assembly, be subjected to the sprocket of chain drive identical in its structure and the bicycle rear, side by power wheel on the drive sprocket is fixed with a pin, the garden week of the correspondence of power wheel adjacent side is provided with 1～10 pin-and-hole, and auxiliary sprocket wheel is walked around in a rear end of being fixed in lever of chain, drive sprocket, be fixed in the front end of lever;

Three, brake portion: form by brake treadle, treadle spring, friction plate, dish spring and bearing, the brake treadle is the metallic rod of one or three sections shapes, the epimere cross section is square, be placed in the guiding square hole of stripe board, the epimere of brake treadle is with the treadle spring, the bottom in brake treadle stage casing is fixed with friction plate, be positioned at the top of power wheel wheel hub, the end of brake treadle hypomere is a wedge shape, be positioned at the top of drive sprocket, on the axle of power wheel, be equipped with the bearing of dish spring and axially loaded near drive sprocket;

Can on stripe board, fix a latch plate;

Can between the front end of lever front end and chain, connect spring;

Can install auxiliary sprocket wheel in a side of road wheel support.

The utility model small volume and less weight, rational in infrastructure, utilized lever principle dexterously, human body gravity partly is converted into onward impulse, thereby it is laborsaving, quick to walk, and reliable brake apparatus is arranged, and security is good, both can in the city, replace bicycle to make the vehicles, also can replace roller skate, slide plate do teenager's use of moving.

Fig. 2 is a vertical view of the present utility model.

Fig. 3 is an A-A profile of the present utility model.

Fig. 4 is a B-B profile of the present utility model.

Details are as follows below in conjunction with accompanying drawing:

Stripe board 1 and foot piece 19 are fixed together, be fixed with latch plate 17 above the stripe board 1, when falling, plays by lever 4 cushioning effect, be equipped with road wheel 2 below the front end of stripe board 1, one side of road wheel 2 supports is equipped with auxiliary sprocket wheel 20, be equipped with power wheel 18 below the rear end, the end of foot piece 19 is equipped with auxiliary wheel 7, lever 4 is hinged by the afterbody of pin and stripe board 1 at bending part, the front portion of lever 4 can be lifted neatly, the rear end falls simultaneously, pedal 3 is arranged above the lever 4, connect by sliding sleeve between them, pedal 3 can slide in the front portion of lever 4, be fixed with shoestring 11 above the pedal 3, in order to hitch the instep of walker, on the axle 16 of power wheel 18, be equipped with drive sprocket 8, it is a sub-assembly, it is constructed and is subjected to the sprocket of chain drive identical in the back wheels of vehicle automatically, when chain 5 moves forward, drive sprocket 8 can not make power wheel 18 stressed rotations, drive sprocket 8 is fixed with a pin 14 by power wheel 18 1 sides, the corresponding garden week of power wheel 18 respective side is provided with 3 pin-and-holes, connect transmission by pin 14 between drive sprocket 8 and the power wheel 18, when chain 5 moves backward, drive sprocket 8 drives power wheel 18 and walks forward, a rear end of being fixed in lever 4 of chain 5, walk around auxiliary sprocket wheel 7, drive sprocket 8, auxiliary sprocket wheel 20, be fixed in the front end of lever 4 by chain spring 6, along with swinging up and down of lever 4 chain 5 is seesawed, brake treadle 9 epimere cross sections are square, be placed in the guiding square hole of stripe board 1, the epimere of brake treadle 9 is with treadle spring 10, the bottom in brake treadle 9 stage casings is fixed with friction plate 12, be positioned at the top of power wheel 18 wheel hubs, brake treadle 9 hypomere ends are wedge shape, be positioned at the top of drive sprocket 8, on the axle 16 of power wheel 18, the bearing 15 that dish spring 13 and axially loaded are arranged near 8 of drive sprockets, so that when non-braking state, drive sprocket 8 and on pin 14 and power wheel 18 be close to, when brake, brake treadle 9 moves down, its lower end separates drive sprocket 8 and power wheel 18, friction plate 12 is pushed down power wheel 18, and it is stopped operating.

During walking, two pin are all put on this footwear voluntarily, when certain pin lifts, sole lifts lever 4 by shoestring 11 and pedal 3, chain 5 moves forward under the pulling of lever 4 front ends, because drive sprocket 8 and bicycle chainwheel identical construction and effect, do not influence the rotation of power wheel 18 and advance this moment, foot-operated following time, the rear end pulling chain 5 of lever 4, drive drive sprocket 8 by

auxiliary sprocket wheel

7 and 20, make power wheel 18 to overtake, go round and begin again, the people constantly strides forward, the just staggered driving force of obtaining of the footwear voluntarily of bipod, when speed is very fast, can no longer take a step, slide forward by inertia, in emergency circumstances, available pin drives pedal 3 and moves after on the lever 4, make heel push down brake treadle 9, its lower end sphenocephaly inserts between drive sprocket 8 and the power wheel 18, and they are separated, make drive sprocket 8 idle running, human body is in stable state, and and then friction plate 12 props up power wheel 18, makes the very fast brake of footwear voluntarily, when continuing to move ahead, lift pin and will make pedal 3 reaches, brake treadle 9 rises under the elastic force effect of treadle spring 10, and friction plate 12 leaves power wheel 18, the sphenocephaly of brake treadle 9 is extracted, under the thrust of dish spring 18, the pin 14 on the drive sprocket 8 will insert in the pin-and-hole of power wheel 18 sidewalls along with the rotation between drive sprocket 8 and the power wheel 18, and footwear can have been walked forward again so voluntarily.
