Abstract
The utility model relates to a stairs climbing carriage with engaged wheels for getting rid of tiredness of people going upstairs and downstairs and difficulty of lower limb handicapped people going upstairs and downstairs. The utility model uses a handle or a motor to drive wheels of a special shape so that a conjugate engaged relationship is formed between the wheels and the treads of stairs, so a person can sit on a carriage, smoothly moving up and down along stairs or pushed by another person on stairs. A safety arrangement is arranged at the place of the handle or the motor to ensure that the driven wheels do not inverse when the chair goes upstairs or rotate in a higher speed caused by the gravity when the chair goes downstairs.
Description
The utility model belongs to the light industry and machinery field, and it relates to a kind of wheeled car of climbing the house stair.
In order to reduce the fatigue that people go downstairs in building, elevator and escalator have extensively been adopted both at home and abroad.At the building below seven layers, China does not often establish elevator for height, and foreign data was once reported rotating three forks and settled the roundlet wheel and utilize form such as crawler belt to come the device of cat ladder, yet there are no in China and drove wheeled climbing ladder apparatus.
Order of the present utility model is oneself to shake handle or control motor by adopting the wheel and the necessary security device of special shape, the people can being seated, and orders about dolly stair activity reposefully, thereby reduces cat ladder fatigue, solves the lower limb disability people and goes up difficulty downstairs.
The purpose of this utility model is achieved through the following technical solutions:
The wheel of three special shapes is set on a dolly, the profile of tooth of wheel is asymmetric, left and right sides profile is respectively the conjugate surface of step vertical surface and horizontal surface, wheel by chain-driving 1,2 be driven after jiggle bar 4 or motor link to each other, during driving the row tower wagon can be voluntarily stair activity reposefully, on the level land, can make short distance voluntarily, also can go up pacifically and be carried out at step.For preventing that wheel reversing from moving down, at handle 4 or motor place a kind of safety device is set, it is by nut 5, friction disc 6, ratchet 10 compositions such as grade, wherein nut 5 and friction disc 6, handle 4 is the fixed one that are, dextrorotation screw mandrel 8 and screw mandrel friction disc 9 are consolidated, dextrorotation screw mandrel 8 vehicle frame is relatively made axial motion, when handle 4 rotates towards the place ahead, by nut 5 friction disc 6 is moved to left, compress ratchet friction disc 7 and screw mandrel friction disc 9, driving drive sprocket 11 rotates, at this moment the ratchet on the ratchet friction disc 7 slips on ratchet 10, and wheel is rotated forward, climbs up stair.Because the effect of ratchet 10, ratchet friction disc 7 can not reverse, thereby drive sprocket 11 can not reverse voluntarily with wheel and moves down.In the time of downstairs, the person for driving a car faces down, sentence the accuser to the punishment facing the person he falsely accused onboard, opposite sense rotates when impelling handle 4 courts and going upstairs by external hand lever, nut 5 drive friction discs 6 are moved to right throw off the ratchet friction disc 7 that is withstood by ratchet 10, so that screw mandrel friction disc 9 loosens, make with the sprocket wheel 11 of friction disc 9 concrete mutuallies and wheel and can order about counter-rotating down at gravity, dextrorotation screw mandrel 8 is also done the negative side and is rotated, impel nut 5 drive friction discs 6 to move to left again again and compress ratchet friction disc 7, thereby withstood by ratchet 10, wheel stops operating thereupon, when the continuous backward rotation of handle 4, sprocket wheel 11 could drive the continuous backward rotation of wheel.When handle 4 was nonreversible, wheel just can not reverse.Make wheel downstairs the time, guarantee smooth operation thus.
The utility model is simple in structure, cheap, for providing a kind of can being seated, people go up new device downstairs voluntarily, when on step, travelling as carrying out smooth ramp, steady safety, can reduce people and step on building fatigue, also can be for used downstairs on the lower limb disability people, special shape wheel of the present utility model also can be used for the manufacturing of perambulator, chair coach, warehouse loading-unloading vehicle and toy cat ladder car.
Shown in Figure 1 is the fundamental diagram of nibbling wheel row tower wagon.
Shown in Figure 2 is the safety device schematic diagram.
That shown in Figure 3 is the wheel contour figure that nibbles wheel row tower wagon.
Shown in Figure 4 is the block diagram of nibbling wheel row tower wagon.
1,2,3,4 narrate embodiment of the present utility model with reference to the accompanying drawings: the wheel 3 that three special shapes are set on the about one meter dolly of length, the wheel contour surface has rubber face again, they link to each other with jiggle bar 4 by chain-driving 1,2, for making hand power suitable, getting the chain-drive ratio is 4 to 8.When people sit onboard handle when the place ahead is shaken, wheel of two wheels in the place ahead and rear can rotate synchronously, order about dolly by the engagement of wheel contour and step and climb up stair reposefully, move down, a kind of safety device is set at handle 4 or motor place for preventing wheel reversing.When handle 4 rotates towards the place ahead, by nut 5 friction disc 6 is moved to left, compress ratchet friction disc 7 and screw mandrel friction disc 9, drive drive sprocket 11 and rotate, at this moment the ratchet on the ratchet friction disc 7 slips on ratchet 10, and wheel is rotated forward, climbs up stair.In the time of downstairs, the person for driving a car faces down and sentences the accuser to the punishment facing the person he falsely accused onboard, opposite direction is rotated when impelling handle 4 courts and going upstairs by external hand lever, make nut 5 drive friction discs 6 and move to right to throw off and withstood motionless ratchet friction disc 7 by ratchet 10, wheel orders about down towards direction opposite with upstairs the time at gravity and rotates and make the dolly descending stair.When wheel changeed slightly, driving dextrorotation screw mandrel 8 by chain changeed slightly, impelled friction disc 6 to be moved to the left again and compressed ratchet friction disc 7 and screw mandrel friction disc 9, stop wheel to be rotated further, have only when handle 4 continuation counter-rotatings, wheel just can be rotated further, and quickens the danger that moves down when having avoided downstairs like this.
For make dolly can be on step smooth running, the utility model has used instantaneous Center and conjugate curves principle, wheel is four dental star shapes, the shape of each tooth is asymmetric, wherein contour surface 13 and step horizontal surface conjugation play engagement during ladder on dolly, be similar to the pure rolling state between wheel face and horizontal tread, the vertical surface conjugation of contour surface 12 and step plays engagement when the dolly descending stair.Be of a size of flat widely 26 centimetres, perpendicular high 16 centimetres for the step of general six laminar houses, garden, the top diameter of the wheel of picking up the car thus is 51 centimetres, and root garden diameter is 25 centimetres.For dolly can be moved on the level land, at the increment of wheel empty cover roundlet wheel is set, and sets up chain-driving and driven.Row tower wagon front and back wheel carrier can be designed to hinged, by universal-joint is set, capable tower wagon can be turned on the level land, can utilize latch that the front and back wheel carrier is fixed when keeping straight on step.The ratchet 10 at dolly handle place can be made into controllable type, so that dolly is holding up handle to carry out on step by other people.
