Abstract

The utility model relates to an exercise body building vehicle comprising a vehicle frame which comprises a front wheel, a handle operating the front wheel and two back wheel axles. Two back wheels are respectively fixed on the back wheel axles and are respectively driven by two one-way ratchets. Each pedaling rod set of two pedaling rod sets is provided with a center part pivoted on a pivoting rod of the vehicle frame. Two chains respectively pass by the two ratchets. The two chains are provided with two ends and are fixed on the pedaling rod sets. When the speeds of the back wheels are not synchronous, the utility model can easily turn. The utility model has the advantages of safety, stability and easy control.

Description

The sport and body-building car

The utility model relates to a kind of health and fitness facilities, and particularly a kind of have two override type driver trains, and it can drive the sport and body-building car of this two trailing wheel respectively.

Current people use sports equipment body-building more and more universal.Traditional sports equipment such as treadmill and exercise bicycle are indoor sport, and quite dull.Therefore, the motion of Hu Wai bicycle and three-wheel vehicle is also more and more welcome.

About bicycle, be not that everyone can ride.Basically, three-wheel vehicle, safety and stable easier than bicycle.For those be not suitable for by bike or can people by bike for (such as child, the elderly, weak sufferer or the like), by tricycle seemingly than better motion by bike.

The representative type three-wheel vehicle comprises a front-wheel and two trailing wheels, and this two trailing wheel is to be fixed on the hind axle, and rotates with the work hind axle.This traditional three-wheel vehicle then has the rotary driver train of mono-, in order to driving this hind axle, and then this two trailing wheel is driven synchronously by single driver train institute.Because there are difficult problem of turning in no any differential gear set on this hind axle, this three-wheel vehicle when turning left or turn right.

Main purpose of the present utility model is, a kind of sport and body-building car is provided, and it has the driver train of two override types, so that can drive trailing wheel respectively, and makes turning easier.

A time purpose of the present utility model is, a kind of sport and body-building car is provided, and it is to be driven by the driver train of two pedal shapes respectively, therefore, can reach the effect that motion is trampled in repetition up and down, and can allow user's upper body be kept upright.

The purpose of this utility model is realized by following technical scheme.

A kind of sport and body-building car is characterized in that, comprises a vehicle frame, two trailing wheels, two override type driver trains, wherein: described vehicle frame comprises a leading portion, this leading portion has a front-wheel and in order to controlling this front-wheel handle, and has a back segment, and this back segment is provided with two hind axles; Described two trailing wheels are to be individually fixed on this hind axle; Described two override type driver trains are in order to drive this trailing wheel respectively; Described each driver train comprises: a single direction ratchet, and it is to be fixed on this hind axle; One treadle group, it has a central portion and is hubbed on the hinged arm of this vehicle frame, and this treadle group has one first end and one second end; One pedal, it is to be fixed on first end of treadle group; One chain, it is to walk around this ratchet and have one first end to be fixed on the desired location of this treadle group, reaches one second end elder generation connection one elastic element and is fixed in second end of this treadle group again, and by this chain, make this treadle can drive this trailing wheel and this ratchet.

The utlity model has the driver train of two override types, can drive trailing wheel respectively, and make turning easier; And the driver train by two pedal shapes drives respectively, therefore, can reach the effect that motion is trampled in repetition up and down, and can allow user's upper body be kept upright.

The purpose of this utility model can also further realize by following technical measures.

In the aforesaid sport and body-building car, described elastic element is a spring.

In the aforesaid sport and body-building car, described treadle group is L shaped, and this predetermined point is between second end of this central portion and treadle group.

For further understanding technology contents of the present utility model, characteristics and effect, exemplify following preferred embodiment now, and conjunction with figs. is described in detail as follows:

Fig. 1 is a schematic perspective view of the present utility model.

Fig. 2 is the birds-eye view of latter half of the present utility model.

Fig. 3 and Fig. 4 are action scheme drawings of the present utility model.

See also Fig. 1 and Fig. 2, the utility model comprises: a vehicle frame 10, and it comprises a leading portion 11, and this leading portion 11 has the handle 13 of a front-wheel 12 and in order to control this front-wheel 12, and has a back segment 14, and this back segment 14 is provided with two hind axles 15.

Two trailing wheels 20, it is to be individually fixed on this hind axle 15.

Two override type driver trains 30 are in order to drive this trailing wheel 20 respectively.When this two trailing wheel 20 was driven with different rotating speeds by this two driver train 30, the utility model can satisfy the required differential ratio of wheel when turning to as the sport and body-building car.

About this two driver train 30, each driver train 30 wherein comprises: a single direction ratchet 31, and it is to be fixed on this hind axle 15; One L shaped treadle group 32, it has a central portion 321 and is hubbed on the hinged arm 16 of this vehicle frame 10, and this treadle group 32 has one first end 322 and one second end 323; One pedal 33, it is to be fixed on first end 322 of this treadle group 32; One chain 34, it is to walk around this ratchet 31 and have one first end 341 to be fixed on the desired location of this treadle group 32, one second end 342 connects an elastic element 35 (for example being a spring) earlier and is being fixed in second end 323 of this treadle group 32, and, make this treadle 32 can drive this trailing wheel 20 and ratchet 31 by this chain 34.

Operating principle of the present utility model is: as shown in Figure 3, when the user ride on this pedal 33 time, can make 32 pairs of hinged arms of this treadle group 16 rotation, and this elastic element 35 can be stretched elongated (storing energy).The user lifts pin, and as shown in Figure 4, this elastic element 35 can restore to the original state (releasing energy), and, this pedal 33 will on move.This moment, this chain 34 can drive single direction ratchet 31 rotations, and then drives the trailing wheel rotation.Therefore, by this mode that repeats to trample three-wheel vehicle is advanced.This mode is different fully with traditional rotation mode.

The utility model can reach the motion that repetition is trampled up and down, and user's upper body be kept upright (similar walk).Yet when doing this motion, user's head, neck and waist (particularly vertebra) all are kept upright substantially, therefore, can significantly reduce the possibility of injury vertebra.

Note that this two treadles group 32 is to drive this two trailing wheel 20 respectively, therefore, this two trailing wheel 20 can be driven respectively by this two driver train 30.Because this two trailing wheel 20 can have different speed, so the utility model can turn left or turn right easily.In addition, this chain 34 and ratchet 31 can be modified as the belt and the pulley of equivalence.

So, exercise car of the present utility model, it has the driving mechanism of two override types, so that can Drive respectively trailing wheel, and turn easily. So, the utlity model has safety, stable and easily control The advantage of system.
