Abstract

The utility model discloses a multifunctional carriage with multiple wheels suitable for flat ground and stair climbing. The utility model can be pushed on the flat ground and go up and down on the stair steps having difference heights and widths. The utility model is provided with a traveling mechanism composed of two rows of multiple wheels; the traveling mechanism is arranged on both sides of the carriage frame; the carriage frame is provided with a device for fixing the goods. The carriage can be used as a transportation means; by utilizing a seat board, a sleep board and a bottom board of the carriage which are folded and suspended on the wall board of the carriage, the carriage can be used as a baby carrier, a children's bed and a cradle, realizing one object with multifunction.

Description

Multifunctional carriage with multiple wheel suitable for flat ground and stair climbing

The utility model is light hand barrow, especially for family delivery weight (in the limit 30kg), and the dolly of advance on the level land stair activity and perambulator for baby, Children, shaking table.

The hand barrow of the terminal castor of the claw-shaped wheel of prior art and cross, solved the problem of delivery weight stair activity, be characterized in the in service of going up or down stairway, claw type or criss-cross wheel carrier roll, every one week of rolling of wheel carrier, just have three times or No. four castors contact to earth, and the continuous conversion of the wheel that contacts to earth, dolly takes place three times or four times and impacts, and running stability is poor, it is more serious when inconsistent particularly to exert oneself, and the dolly purposes is single.

The purpose of this utility model is that robust motion is poor when solving that wheel carrier rolls in the prior art, exerts oneself inconsistent and the dolly purposes is single and the building multiservice car is climbed on the design-calculated level land.

The utility model is to be installed in the under-carriage both sides with the double walking mechanisms of taking turns more.The double many wheels of every side, its bearing pin (1), (2), (among Fig. 1) interlaces and is installed among Fig. 3 in the middle of the off-side wheel frame (3) on the inboard wheel carrier of wheel carrier (4) (5), and frame panel (9) is the flat two ends arc that makes progress, and the two ends of the outside, centre, inboard wheel carrier also are arcs upwards.Wheel is with minor diameter rubber tire (6), is installed on the wheel carrier by bearing pin (1) and makes axial restraint with spring cotter (7).When making transportation means, goods (8) is placed on the car tank top plate (9), uses the safety belt fastening.The suitable angle of the seat of vehicle frame wallboard, the plate of sleeping (suspension type) upset will be articulated in when making perambulator, Children, shaking table and just the baby that sleeps can be sat.The time spent is not with handlebar (10) and the suitable angle stored collapsed of car wall panel (11) rotation.

Compared with the prior art, this dolly handling characteristics is when stair activity, and the double wheel of both sides contacts the ladder angle of stair in turn, is linked as baseline with the wedge angle of each ladder, is raceway.The installation because the wheel shaft of double wheel interlaces, the pit between row's adjacent wheels is just remedied by the vertex of another row's wheel, remedies so mutually, form the raceway plane of the difference of a convex-concave less than certain value, realized the continuous movement of dolly, guaranteed to operate steadily, impacted less.Dolly is when stair activity like this, and its state of kinematic motion becomes on the inclined-plane that becomes with the stair dihedral makes continuous movement, and the user only needs to overcome the sliding force of dolly on the inclined-plane with a kind of pulling force just can stair activity.Double many wheels of both sides form straight raceways, advance not to be subjected to the restriction of ladder (among Fig. 2) (13), (14) height and ladder.The minor diameter rubber wheel is light, damping, noiselessness.For safe in utilization, also be provided with a brake gear, whole dolly is realized one-object-many-purposes.

Description of drawings: Fig. 2 is the scheme drawing of vehicle structure and stair activity, and Fig. 1, Fig. 3 look up and section-drawing for dolly.

The utility model embodiment, become wheel carrier (3), (4), (5) with punching of the steel plate, with attaching parts (12) horizontal connecting panel (15) and car bottom plate (9) are fixed together, wheel is contained on the wheel carrier with bearing pin (1), (2), makes axial restraint with spring cotter.Handlebar (10) is anti-arc with steel pipe manufacturing, and the lower end is connected with pin with car wall panel, can rotate 150 ° around bearing pin, and needs during according to use are adjusted corresponding angle.The framework steel pipe manufacturing of car wall panel (11), and hinged with under-carriage.Perambulator seat, the plate of sleeping are suspended on the car wall panel with thistle board, canvas.

Claims (3)

1, a kind of stairs and flat land multiservice car is made up of vehicle frame, walking mechanism, handlebar (10), brake gear etc., it is characterized in that walking mechanism is made up of double many wheels, is installed on the wheel carrier (3), (4), (5) of vehicle frame both sides.

2, multiservice car according to claim 1 is characterized in that the double walking mechanism of forming of taking turns more, and two row's wheel bearing pins interlace and are installed on interior middle off-side wheel frame (3), (4), (5).

3,, it is characterized in that the two ends of wheel carrier (3), (4), (5) are arc upwards according to claim 1,2 described multiservice cars.
