Abstract

The utility model relates to a pair of pedal force driving type roller skates, which can run forward only by pedaling on the ground by two feet in turns without pedaling backward by force. Each roller skate comprises a shoe bridge plate, two front wheels which are arranged on a front shaft are arranged under the shoe bridge plate, and two back wheels are arranged on a back shaft. The utility model has a key point that the shoe bridge plate is provided with a pedal and pressure supporting bracket which contacts a driving mechanism from a notch point of the shoe bridge plate. In the driving mechanism, a flywheel drives the back shaft. A user does not need to pedal the ground, the utility model can glide only by pedaling the ground, the utility model has the advantages of easiness, labor saving, simple structure and low cost, and the user has a good time in the game.

Description

Foot power driven formula roller skate

The utility model is a kind of motor play equipment, is to be suitable for the single roller skate that slides.

The teenager likes roller skate, has only four wheels under the pedal of present roller skate, and the reaction force by pedaling behind the pin when advancing slip must the bipod exchange could continue to advance with pedaling, and physical demands is bigger, and skill is difficult to grasp.

The purpose of this utility model provides a kind of needs both feet to step on ground in turn, pedals the foot power driven formula roller skate that just can move ahead after must not exerting oneself.

The purpose of this utility model is achieved in that it comprises the footwear bridge plate, there are two front-wheels to be contained on the front axle under the plate, two trailing wheels are contained on the rear axle, main points are: the trampling support is housed on the footwear bridge plate, the trampling support drives rear axle with flywheel from the indentation, there Contact Transmission mechanism of footwear bridge plate in the transmission mechanism.

Said transmission mechanism is that a flywheel is housed on the rear axle, has chain to walk around flywheel, and the upper end of chain is fixed on the back transverse slat of footwear bridge plate indentation, there, and the lower end of chain links one pulls the bow, and pulling the bow is fixed on the below of preceding transverse slat.

Said transmission mechanism is that rear axle the place ahead has two parallel relay axle and force transmission shafts, and the relay gear is arranged on the relay axle, and the power transmission gears engaged on it and the force transmission shaft also has flywheel on the force transmission shaft, the pinion on it and the rear axle.

The principle of table utility model is: the both feet as the formula of walking are alternately stepped on ground, make it crooked and produce motion by trampling support compressing chain, drive flywheel and rotate; Or by trampling support drive relay gear and flywheel rotation, thereby wheel shaft is rotated.Make roller skate produce motion forward by legpower, and after pressure was cancelled, owing to used flywheel, wheel shaft can not reverse.Bipod alternately steps, and just makes roller skate continue to slide.

The utility model has the advantages that: must firmly not pedal ground, as long as just can slide, easily laborsaving, another has a kind temperament and interest in the recreation with stepping on gently, and it is simple in structure, and is cheap.

Details of the present utility model provides by following examples and accompanying drawing thereof:

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the upward view of Fig. 1.

Fig. 4 is another embodiment driver composition of the utility model.

With reference to the accompanying drawings 1-3, the utility model comprises footwear bridge plate 1, has two front-wheels 2 to be fixed on the front axle 10 below the plate, and two trailing wheels 6 are fixed on the rear axle 11.Diaxon is contained on the footwear bridge plate 1 by bearing 9, central authorities also have flywheels 12 at rear axle 11, have bicycle chain 3 to walk around flywheel 12, and the upper end of chain 3 is fixedly on the back transverse slat 8 of footwear bridge plate 1 indentation, there, the lower end links pulls the bow 4, the 4 preceding transverse slats 5 times that hang over the front portion of footwear bridge plate 1 of pulling the bow.The resilient trampling support 7 of harness above the breach of footwear bridge plate.

During use, roller skate is fastened on pin with rope, band, both feet are alternately stepped on ground, press frame 7 compressing chains 3 to make it crooked by support, thereby affect flywheel 12 to rotate, and drive roller skate and advance, at this moment, 4 elongations of pulling the bow; When pin lifted, support pressed frame 7 to break away from chains 3, and under 4 the pulling force effect of pulling the bow, chain 3 resets, and the oppositely idle running thereupon of flywheel 12 this moment does not drive wheel shaft reverse turn.So repeatedly.

Attached 4 according to figure, this example has front side board 18 below footwear bridge plate 1, and front axle 2 is installed, and also has back side panel 19, and relay axle 14, force transmission shaft 17 and rear axle 11 are installed.Relay gear 13 is housed on relay axle 14, and power transmission gear 16 engagements on it and the force transmission shaft 17 also have flywheel 12 on the force transmission shaft 17, and pinion 15 engagements on it and the rear axle drive rear axle and rotate.Elasticity support 7 contacts relay gear 14 from the indentation, there of footwear bridge plate 1, and works by the foot-operated relay gear 14 that presses.

Claims

1, foot power driven formula roller skate, it comprises the footwear bridge plate, has two front-wheels to be contained on the front axle under the plate, two trailing wheels are contained on the rear axle, it is characterized in that: the trampling support is housed on the footwear bridge plate, and the trampling support drives rear axle with flywheel from the indentation, there Contact Transmission mechanism of footwear bridge plate in the transmission mechanism.

2, roller skate according to claim 1, it is characterized in that: said transmission mechanism is that a flywheel is housed on the rear axle, has chain to walk around flywheel, and the upper end of chain is fixed on the back transverse slat of footwear bridge plate indentation, there, the lower end of chain links one pulls the bow, and pulling the bow is fixed on the below of preceding transverse slat.

3, roller skate according to claim 1 is characterized in that: said transmission mechanism is that rear axle the place ahead has the relay axle, and the relay gear is arranged on it, and the power transmission gears engaged on it and the force transmission shaft also has flywheel on the force transmission shaft, the pinion on it and the rear axle.
