Abstract

The utility model provides a roller skate type man carrying device which runs by pedaling by two feet. The device can run on a general road surface; each skating shoe is composed of a supporting rack, a foot pedal, a gear train and four rollers; when the two feet alternately pedal the foot pedal of each skating shoe, an internally connecting rack bar which is connected below the foot pedal moves up and down so as to drive gears to be engaged with the internally connecting rack bar; the rotary speed is improved through the transmission of the gear train; at last, a back wheel is driven to rotate, and the rotation of the back wheel can drive the utility model to carry people to run forwards. The device is also provided with a pull switch which is braked by pulling a flexible cable.

Description

Skating shoes

The present invention relates to a kind of muscle-powered manned device that uses, particularly a kind of can be used on the general road steps and the manned device of the roller skate formula of travelling by both feet.

Existing roller skate can only be used for smooth cement field.It only is made up of bearing support and four rolling.When the people is wearing it when travelling forward, forward lean from the analysis of power as can be known, has a component directed forward.Because smooth cement field and the frictional force between roller are little, this component can overcome the frictional resistance between roller and ground fully and the people is travelled forward.But in the time of on general road, because frictional force is big between road surface and roller, this component then is difficult to overcome the resistance on road surface.Therefore roller skate is not suitable for general road surface.

The purpose of this invention is to provide a kind of improved roller skate.It can travel on general road, rides instead of walk to reach, the purpose of amusement.

Task of the present invention is finished as follows: both feet are put on a pair of foot-operated roller skate.When a pin, right crus of diaphragm for example when depressing the pedal on the foot-operated roller skate, is connected in and connects tooth bar in the garden arc pedal under and just move downward, and drives meshed gears, improve rotating speed by the gear train transmission again after, drive the trailing wheel rotation at last.The rotation of trailing wheel makes that foot-operated roller skate is manned moves forward.Subsequently, heel lifts, and under the spring tension effect, pedal lifts and returns original position again.Simultaneously, under the left threading, this moment left foot foot-operated roller skate manned the moving forward as driving footwear again, the foot-operated roller skate of right crus of diaphragm is then as driven footwear.

Therefore, double-legged alternately depresses and lifts, and it is to overtake manned just to drive foot-operated roller skate.

Below with reference to accompanying drawing invention is described in further detail.

Fig. 1 is a concrete structure master pseudosection of the present invention.

Fig. 2 is the vertical view of throwing off behind upper cover and the pedal.

See figures.1.and.2, the pedal that can swing up and down fulcrum 1. is contained in bearing support and 3. goes up, and is connected under the pedal in the garden arc and connects tooth bar 2..When foot-operated pedal down 1., in connect tooth bar and 2. move downward, drive the gear (12) that is engaged with.Gear (12) 7. is to be connected by key with ratchet, thus ratchet 7. driven wheel 8. speed ratio is improved D ₇/ D ₈Value.Gear 8. with gear 9. with one, so 9. with the 8. same rotating speed driven wheel of gear 10. gear improves D with speed ratio again ₉/ D ₁₀Value.10. gear is connected with ratchet (11) key, and last ratchet (11) driven wheel (13) improves D with speed ratio simultaneously ₁₁/ D ₁₃Value (D ₇/ D ₈D ₉／D ₁₀。D ₁₁/ D ₁₃Design load be 8.8）。Gear (13) and trailing wheel are coaxial rotation, so trailing wheel just can rotate along with the rotation of gear (13), thereby it is to overtake manned to drive foot-operated roller skate.

Subsequently, heel lifts, and pedal is homing under spring pulling force effect 4..Reverse drive gear train when preventing that tooth bar from moving upward, 8. gear adopts ratchet.Equally, when these skating boots were dragged by inertia traveling or quilt, for preventing trailing wheel reverse drive gear train, gear (11) also adopted ratchet.

In bearing support front portion 3. brake apparatus is housed also.This apparatus structure is such, and a slide block (15) is arranged in sleeve (16), and slide block (15) is connected with drag-line (14).When the tension drag-line, slide block just can stretch out downwards, touches ground, and the friction on slide block and ground just can stop these skating boots to travel forward and reach the braking purpose.When no longer straining drag-line, slide block is withdrawn under the effect of spring (17) in the sleeve (16).
