Abstract

The utility model discloses a driver especially used for a sitting and recumbent type bicycle and a bicycle wheelchair. The driver consists of a big support, a small support, a guide rod, a sliding block, a guide pin, a steel wire rope connected into a whole, as well as two flywheels and a chain wheel which are arranged on the same axle, and two pairs of pulleys. The utility model has the advantages that the cost is low, the operation is convenient and comfortable, and the utility model solves the driving problem for producing a sitting and recumbent type bicycle and a bicycle wheelchair which are suitable for being used for middle and old aged persons.

Description

Sitting and lying type bicycle, wheelchair, special purpose driver voluntarily.

The utility model relates to Bicycle, is a kind of circular movement that pedal is done during bicycle specifically, changes over the special purpose driver that seesaws.

The bicycle of Xiao Shouing all is a riding type car in the market.Height, center of gravity height, stability, traveling comfort that the riding type car people sits are poor, and frontal resistance is big.

The purpose of this utility model is to provide a kind of sitting and lying type bicycle or the used special purpose driver of wheelchair voluntarily.

To achieve these goals, the utility model adopts following technical scheme; A kind of sitting and lying type bicycle, wheelchair special purpose driver voluntarily is characterized in that; Big support top be provided with pilot bar, slide block, pedal, slide block by towing pin link to each other with chain, the two ends of chain are connected steel rope, steel rope is walked around the fixing chain of two groups of pulleys that is installed in big support front portion.Chain be installed in that two flywheels engagement on the small rack, two flywheels and chain wheel are fixed on the axle housing jointly, the stamen axle is housed in the axle housing, the stamen axle is fixed on the small rack.

Good effect of the present utility model is the circular movement of bicycle pedal transformed into and moves forward and backward, and has cancelled the essential minimum terrain clearance of former step.Make bicycle can make sitting and lying type, center of gravity reduces, and reduces frontal resistance, has increased stability, traveling comfort and safety.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is that the utility model is formed structural representation;

Fig. 2 is the birds-eye view of Fig. 1;

Fig. 3 is the structural representation of pilot bar, slide block, pedal.

Fig. 4 is the structural representation of steel rope, chain, assembly pulley, flywheel, pedal.

Fig. 5 is the structural representation of flywheel, chain wheel, stamen axle.

See also Fig. 1, shown in Figure 2; Big support 1 top be provided with pilot bar 3, slide block 4, pedal 5, slide block by towing pin 9 link to each other with chain 8, the two ends of chain are connected steel rope 7, steel rope is walked around the fixing chain of two groups of assembly pulleys 6 that is installed in big support front portion.Chain be installed in that two flywheels 10 engagement on the small rack 2, two flywheels and chain wheel 11 are installed on the stamen axle 12 jointly, the stamen axle is fixed on the small rack.

When the utility model used, when a pedal reach, slide block moved forward along pilot bar, was fixed on the towing pin pulling chain reach on the slide block, then drove flywheel, chain wheel rotates on the stamen axle.Simultaneously steel rope is walked around assembly pulley and is driven another pedal and retreat.Chain wheel is then takeoff output.
