Description

Single-wheel turns to and drives dual-purpose perambulator

This patent belongs to the vehicle mechanical field.

The type of common perambulator is more.Wherein major part is the bicycle of additional two auxiliary wheels in four-wheel type, three-wheel type, two-wheeled type or both sides, two-wheeled back.The former is simpler, but appearance property is poor slightly; Latter's better performances, but more complicated, cost is higher.

The purpose of this patent is to turn to type of drive to dig a kind of external form uniqueness of system, flexible stable, simple and reliable, the dual-purpose perambulator of pushing riding with single-wheel.

Fig. 1, Fig. 2 are respectively the dual-purpose perambulator of this patent mechanisms.Wherein Fig. 1 constitutes the perambulator of riding after loading onto steering handle 21, seat 20; Fig. 2 loads onto lie in bed 22 doll carriage of baby.

Among Fig. 1 and Fig. 2: 1-front-fork, 2-extension spring, 3-front wheel carrier, auxiliary wheel before the 4-front wheel carrier axle, 5-, auxiliary wheel shaft before the 6-, 7-vehicle frame, 8-main wheel, 9-main axle, 10-pedal arm, the 11-pedal, 12-main wheel fork, 13-pedal shaft, 14-fender, auxiliary wheel shaft behind the 15-, auxiliary wheel behind the 16-, 17-steering column jacket, 18-binding bolt, 19-seat Xiao, 20-seat, 21-steering handle, 22-baby bed, 23-bed body and bedcover, 24-go-cart handle, 0-main wheel turning center, 01-front-wheel steering center.

When the dual-purpose perambulator of this patent is ridden, load onto seat 20, steering handle 21, be sitting on the seat, hold steering handle, foot pedals 11, pass through pedal shaft 13, pedal arm 10, main axle 9 drive main wheel 8 rotations. The driving vehicle advances, when rotation direction makes 21 the main wheel Plane Rotation (be the short-and-medium arrow of Fig. 1 During head) to the AA plan-position, because offset or dish e between the center of rotation 01 of the center of front auxiliary wheel 5 and front wheel carrier 3. Before when rolling Auxiliary wheel again can 01 rotation around the center. The main wheel Plane Rotation will make front auxiliary wheel go to the BB position around 01 its plane thus. Each wheel is pressed among Fig. 1 respectively The heart line direction of arrow is advanced, and realizes turning to, and need not learn and can directly ride. Wherein seat 20, steering handle 21, degree of tightness fastening bolt 18, capable of regulating height Low to adapt to the children of different heights.

For the baby, the dual-purpose perambulator of this patent is pulled down steering handle 21, seat 20, lie in bed 22 lower end of baby is inserted in the steering column jacket 17, screw binding bolt 18 after adjusting height, promptly constitute the doll carriage of Fig. 2, carry out by the adult.

The feature of this patent is: the centre has only a bigger main wheel, a preceding auxiliary wheel, and auxiliary wheel is that triangular support is around main wheel after two.The main wheel of its center bears big portion weight and has simultaneously and turns to and driving action.

Another feature is: front wheel carrier 3 is hinged with front-fork 1, extension spring 2 is housed therebetween, constitutes resilient suspension, but make preceding auxiliary phase the vehicle frame upper and lower displacement, even auxiliary wheel all lands after uneven road surface also can keep it and main wheel and two, advantages of higher stability is arranged.

This patent by the sample car test, has been realized its intended purposes.

Below be an embodiment of this patent perambulator.

Title: single-wheel turns to and drives dual-purpose perambulator.

Steering mode: steering handle (or bearing circle) direct control main wheel turns to.

Type of drive: foot-operated main wheel drives.

Axle drives: preceding auxiliary wheel shaft and main axle distance: 380 millimeters.

Main axle and back auxiliary wheel wheelbase: 350 millimeters.

Wheelspan: two back auxiliary wheel wheelspans: 680 millimeters.

Main wheel: 1 air-inflation tyre specification 14 " *

Auxiliary wheel: 3, plastic, rubber wheel, outward through 6 ".

The seat: bag is with foamed plastic band backrest seat.

Manipulator: band foamed plastic cloth cover, screen covering sitting-lying double-purpose baby bed.Length * wide=680 * 300 millimeter

Oad (length, millimeter) 1000 * 750 * 800

The advantage of the dual-purpose perambulator of this patent:

1, peripheral 3 little auxiliary wheels, the center only has 1 main wheel, does not have the devices such as chain drive. Structure than the two-wheeled of two auxiliary wheels of normal tape voluntarily Car is much simple. In addition the number of packages amount reduces closely 1/2, and cost can reduce by 1/3～1/2.

2, this car can be used as that the baby carries out and children ride dual-purpose. Little of some months, greatly to youngster Dan Junke use in ten years old. Outward appearance is unique novel, uses year Year is long, easy to use.

3, main wheel in the middle of this car, 3 auxiliary wheels are four-point supporting on every side, front auxiliary wheel is resilient suspension, the soft seat of backrest, stability and comfortableness are Good.

This patent can become perambulator product of new generation. Integrate and push away, ride, play with body-building, be widely used.

Claims

1, single-wheel turns to and drives dual-purpose perambulator, and feature is main wheels of central authorities, 3 triangular in shape being distributed in around the main wheel of less auxiliary wheel.

2, dual-purpose perambulator according to claim 1, feature are that the front-fork and the front wheel carrier of auxiliary wheel is hinged before being equipped with, and the centre is connected with extension spring, and preceding auxiliary wheel is the vehicle frame upper and lower displacement relatively.
