Abstract

The utility model relates to a multifunctional tricycle, which is characterized in that a driving portion is composed of a front wheel, a driving chain wheel arranged before the front wheel, a driven chain wheel fixed on a central shaft of the front wheel, a chain, pedals and a supporter composed of a front fork, a flat fork and a pulling plate. A wheel arranged at the rear part, a front frame and a carriage are connected with the front driving portion through a crossbeam. The utility model has the advantages of compact structure, reasonable design, small tricycle body, beautiful appearance, low gravity centre and strong safety. Since the pedals are arranged before the front wheel, a rider needs to straighten legs forwards forcibly, which has great benefit for the recovery of waist and leg diseases. The multifunctional tricycle is particularly suitable for old people to travel.

Description

Multi-functional tricycle

The utility model relates to and a kind ofly collects manned, loading, the exercise health is the multi-functional tricycle of one, is specially adapted to the elderly and child trip, shopping and exercise health.

Continuous progress along with society, people's living standard is more and more higher, especially the raising of medical condition, people's life-span is constantly being extended to aging, increasing the elderly has formed a huge social colony, is suitable for the problem that problem that the elderly goes on a journey has voluntarily become a socialization.Allow old man oneself start motor-car and to go out the provisional capital by bike be unrealistic and unsafe.Three-wheel vehicle as unpowered vehicle should be the optimal vehicle of the elderly oneself trip.The tricycle of Chu Shouing is various in style in the market, is in various forms.But most of function is a conveying objects is the main tool of production, and vehicle body is high and big, not only takes up an area of but also dangerous as bicycle use.The elderly that not being suitable for especially is in the spends remaining years in comfort shopping of going on a journey, the health of playing and exercise uses.

The purpose of this utility model designs exactly that a kind of vehicle body is low, and car body is little, simultaneously can be manned, and loading, and the health of can exercising are specially adapted to the multi-functional tricycle that the elderly and child use.

This multi-functional tricycle is by drive part, secondary part, and vehicle body, rim brake four parts constitute.Drive part is positioned at the front portion of whole vehicle body, is by front-wheel, is fixed on the driven sprocket on the front-wheel axis, the chain composition that is fixed on the drive sprocket of flat wooden fork leading section and connects driving and driven sprocket wheel.The flat wooden fork other end overlaps with preceding wooden fork bottom and is fixed on the front-wheel axis, wooden fork upper end before arm-tie one end is fixed on, the other end is fixed on the drive sprocket shaft housing, forms a triangle support frame with preceding wooden fork, flat wooden fork, drive sprocket is fixed, on drive sprocket axle, loaded onto two pedals.As long as step the pedal that is connected on the drive sprocket, drive sprocket just can pass through chain-driving, drive driven sprocket and drive the front-wheel rolling, thereby the pulling trailing wheel marches forward.Secondary part is by two trailing wheels, and the vehicle frame that connects two trailing wheel axostylus axostyles and support trailing wheel axostylus axostyle and railway carriage constitutes.By the crossbeam that is connected with preceding wooden fork vehicle frame and before driving are partly linked together, body portion is by railway carriage, is positioned at the seat of driving of railway carriage front portion, and the storage tank of sitting down is driven in taking in the railway carriage.Storage tank behind the railway carriage between the two-wheeled of bottom is formed.Body-hold is on vehicle frame.Rim brake is by restrictor bar, the lock axle that links to each other with restrictor bar, and the brake rubber block that links to each other with the lock axle constitutes, and rim brake is fixed on the vehicle frame by the lock axle, and brake rubber block is relative with rear wheel, adorns a spring on the vehicle frame, when stopping, hooks restrictor bar with spring, and car is braked.

The multi-functional tricycle of the utility model design-calculated, compact conformation, reasonable in design, car body is small and exquisite attractive in appearance, center of gravity is lower, when the cyclist in case of emergency, can rapidly both feet be stepped on and be difficult on the ground falling down, fool proof reliable.Because pedal is positioned at the place ahead of front-wheel, cyclist's both legs of need firmly extending straight forward are very useful to the elderly's waist leg rehabilitation.Be particularly suitable for the elderly be with grandson or my old man go on a journey shopping, visit friends and relatives, use as the vehicle when going on a tour.Simultaneously, for the elderly of those legs and feet inconvenience, this car is the vehicle of trip, is again the apparatus of rehabilitation exercise.

With reference to the accompanying drawings multi-functional tricycle structure described in the utility model is carried out detailed narration below.
