Abstract
The multifunctional handcart which can be used as tool for going up and down stairs is formed from handcart body, handcart frame, hood frame, handlebar, position-changeable rear wheels, front wheels and side wheels with brake, middle wheels, wheel frame, large and small toothed disks, chain and pedals. The front wheels, side wheels and middle wheels are divided into left and right two groups, uniformly fixed on the wheel frame of the handcart frame, the position-changeable rear wheels are fixed on the position-regulating shaft driven by handlebar, and the front wheels can be driven by pedals via small toothed disk, chain and large toothed disk. Said multifunctional handcart can be used as baby-carriage or moving articles.
Description
The present invention relates to a kind of can the level land or on make perambulator downstairs or the carrying article use the multifunctional handcart capable of travelling up stairs that also can ride usefulness for children.
At present, though the carriage for children kind of using in each family is a lot, all be on the level land, to use, during stair activity, because tilting of car body, dangerous reliable and can not use; When on the heavier article of carrying, going downstairs, there is not suitable transportation means yet, for resident in the building, particularly do not have a resident in the building of elevator, as needs transport disease (always) people, baby or during downstairs upstairs than heavy articles, can only depend on Ren Gong Back, embrace, shoulder, lift, not only require great effort but also dangerous, therefore, bring a lot of difficulties and trouble often for these people.Patent documentation is found by retrieval: the patent No.: 95250497.9 the MPV multipurpose vehicle of stair activity " can " and the patent No.: 96213209.8 " crawler type, collapsible, motor-driven, manual, dual-purpose handcart capable of travelling up stairs ", the function that though they all have can be on the level land, use when road and upper and lower stair, all exist complex structure, car body heavy, adjust and use inconvenient deficiency and shortcoming; And when using, motor and power supply need be installed also as powered travel, and its cost is improved, very impracticable.
Purpose of the present invention: design and provide a kind of not only can use on the level land also can be at stair activity the time walking freely, car body remain level, steadily, the failure-free multifunctional handcart capable of travelling up stairs, reach upstairs, transport disease (always) people, baby and during downstairs than heavy articles, time saving and energy saving, safe and reliable, adjust purpose easy to use.
The present invention program's structure design: multifunctional handcart capable of travelling up stairs by car body, vehicle frame, paulin frame, handlebar, front-wheel, variable bit trailing wheel, two cinctures, breast wheel, wheel carrier, little chain wheel, large toothed disk, chain, pin step on, hub brake, iron wire frame form; About two groups, earth point on the same inclined-plane, out-of-alignment front-wheel, two cinctures and breast wheel be installed on the wheel carrier that is fixed on the vehicle frame; Telescopic handlebar is positioned at the handlebar sleeve pipe, and handlebar sleeve pipe lower end is vertically fixed on the positioning axle, and the support that the wheel that positioning axle two ends are positioned at the axle sleeve that is fixed on the vehicle frame and two cinctures is positioned at the variable bit trailing wheel of same vertical plane is fixed on the positioning axle; Be equipped with denticle dish that pin steps on and be fixed on the below of vehicle frame through the chain wheel frame, the chain moving through the denticle dribbling connects with large toothed disk is movable, and the anchor shaft of large toothed disk is fixedly connected through wheel carrier and front-wheel axis hole; Two cinctures are installed in the both sides of wheel carrier, and the breast wheel littler than two cinctures is installed in the inboard of wheel carrier; But the hub brake by brake cable control lock front-wheel and two cinctures is fixed on the wheel carrier; Car body and the paulin frame made by plastic casing are fixed on the vehicle frame, and not only attractive in appearance but also safety seems; Iron wire frame with lock is installed in and adopts on the support of cardan wheel as the variable bit trailing wheel.Among the design: with handlebar by in the handlebar sleeve pipe on draw and before car, remove, the variable bit trailing wheel can be put down, this moment, multifunctional handcart capable of travelling up stairs can use on the level land; When handlebar is moved behind car, the variable bit trailing wheel will be lifted, its earth point is in the earth point of same front-wheel, two cinctures and breast wheel on the same inclined-plane, and walking is more steadily with reliable but their common guarantee multifunctional handcart capable of travelling up stairs car body horizontal surface when stair activity is constant.
Advantage of the present invention, characteristics and good effect:
1, compact conformation, volume is little, and is simple to operate flexible, easy to use.
2, can use on level land or road: the variable bit trailing wheel rises, falls simple in structure, with handlebar by in the handlebar sleeve pipe on draw and when before car, removing, the variable bit trailing wheel can be put down, this moment, multifunctional handcart capable of travelling up stairs can be made perambulator or the fortune article use on level land or road, also can be for children's usefulness of playing by bike.
3, can when upper and lower stair, use: when handlebar is moved behind car, the variable bit trailing wheel will be lifted, this moment multifunctional handcart capable of travelling up stairs can be used to upstairs, transport disease (always) people, baby, children and other article downstairs, avoided Back, embraced, shouldered, lift, time saving and energy saving.
4, car body of being made by plastic casing and the paulin frame that can put article are fixed on the vehicle frame, and practical, safety again attractive in appearance seem.
5, owing to two cinctures, breast wheel are steadily reliable when having adopted in the design and installation that many rows and gap are complementary to make multifunctional handcart capable of travelling up stairs at stair activity.
6, owing to be provided with iron wire frame with lock, when car stops, it is turned down from top to bottom, make position, the angle of cardan wheel opposite locked and can't walk, played the purpose that car body is lockable.
7, since on front-wheel and two cinctures, adopted use for downstairs the time, with the hub brake of brake cable control, played lock firmly or the effect of speed limit, make safety and reliability when transporting article or personnel downstairs.
