Description

Health care cart

The utility model relates to a kind of bicycle, the particularly a kind of bicycle that not only can make the vehicle but also can take exercises usefulness.

Existing bicycle mainly contains two-wheel car and three-wheel vehicle, owing to need the motion of pin by bike, thereby be of value to body-building, still, because bicycle only is suitable for outdoor sport, thereby, under the atrocious weather condition, can not do body-building and use; On the other hand, above-mentioned bicycle can only have the exercise effect to lower limb, and little for the exercise effect at other position of upper limbs and health.Patent application " physical fitness of old man car " (application number 892090170) but a kind of bicycle of rider's trick alternating movement effect has been proposed, can make upper and lower limb and other position of rider obtain taking exercise, but this patent application can only be suitable for outdoor and single use.

The purpose of this utility model be to propose a kind of list double in indoor and outdoor all spendable bicycle, both can be used as a kind of vehicle, can be used as a kind of body-building device again.

Accompanying drawing is a structure principle chart of the present utility model.

Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in detail.

With reference to accompanying drawing, the utility model is by a front-wheel 1, two three-wheel vehicles that trailing wheel 16 is formed.Front-wheel 1 is contained in the front fork 2, trailing wheel 16, flywheel 17, and wagon box 14 is with being contained on the rear axle.Adorning back vehicle seat 13 above the wagon box 14, after poppet 15 is being adorned in both sides.The friction lining 9 of two adjustable distances is housed on vehicle frame 11.Universal-joint 4 is housed in the upper end of front fork 2 to link to each other with handlebar 7, flexibly connecting cross bar 6 on the handlebar 7, flexibly connecting montant 5 on the cross bar 6, two preceding pedals 26 are equipped with in montant 5 lower ends, there are two point of connection the centre of montant 5, above one link to each other with vehicle frame 11, below one link to each other with connecting rod 25, the right-hand member of connecting rod 25 links to each other with bearing 23, partly turn 22 during bearing 23 inboards are connecting, the outside is turned 24 with smaller part and is linked to each other, in partly turn 22 with wheel disc 19, pin turns 21 and is fastened together, smaller part turns 24 and turns back foot 20 all is housed on 21 with pin, and wheel disc 19 links to each other with flywheel 17 on the rear axle by chain 18.

Double when riding with this car, ride in front stall 12 for one, 7, ride preceding pedal 26 with its Hand cart simultaneously, people's application force is by handlebar 7 and pedal 26, give connecting rod 25, partly turn 22 in the bearing 23, drive wheel disc 19 then, wheel disc 19 drives flywheel 17 by chain 18 and rotates, flywheel 17 drives trailing wheel by rear axle and rotates, and car begins to travel; Simultaneously, another people rides in back seat 13, the bipod back foot 20 that presses down with the foot, back foot 20 by pin turn 21, smaller part turns 24, bearing 23, in partly turn 22, drive wheel disc 19 and rotate, front and back two people firmly are combined into a place, drive car and travel.

Single when selecting firmly method by bike, four limbs are identical with the double method of exerting oneself that rides over people in front by bike the time with force method.Select for use two legs to exert oneself method by bike the time, montant 5 must be separated with connecting rod 25, the friction force between friction lining 9 and the montant 5 is transferred to maximum, this moment, handlebar 7 can not move forward and backward, the cyclist makes and can exert oneself by two legs, drives the method that wheel discs 19 rotate with foot-operated back foot 20, and car is travelled.

When the special-purpose exerciser of indoor conduct, two front frames 3 are installed on the both sides of front fork 2, two after poppets are installed on the both sides of wagon box 14, make car be in stationary state.Montant 5 is separated with connecting rod 25, regulate the nut on the bolt 10, the gap between two friction linings 9 changes thereupon, and the friction force size between friction lining 9 and the montant 5 is change thereupon also.When according to after human needs mixes up the friction force size by bike, friction force is passed to handlebar 7 and preceding pedal 26 by montant 5, cross bar 6.The cyclist just can ride on the front stall 12, pulls handlebar 7 and pedal 26, and overcome friction reaches the sport and body-building purpose.

This shows that the utility model is compared with " physical fitness of old man car ", has following characteristics:

1, need ride when using car as two people, the physical fitness of old man car can only a people be ridden usefulness, and another people takes, because of the elderly's health a little less than, be with difficulty of people by bike, make troubles to traffic, also enure health simultaneously.Multifunctional body-building car two people can ride usefulness simultaneously, both convenient traffic, and health has also obtained enure.

2, the single physical fitness of old man car of riding, make car motion, a kind of firmly method that can only adopt four limbs to exert oneself, the multifunctional body-building car is except that adopting this kind firmly the method, also for the rider provides habitually the two legs method of exerting oneself, make the rider can be wherein a kind of according to own needs selection.

3, the physical fitness of old man car can only be in outdoor application, and the multifunctional body-building car also can use at the special-purpose exerciser of indoor conduct, not only can satisfy the elderly's body-building needs, also can be a middle-aged person, the teenager provides fitness tool.
