Abstract

The utility model relates to an adjustable type ladder for passengers to get on and get off. The structure of the utility model comprises a ladder plate which is composed of a ladder vertical plate and a ladder panel. The utility model has the essential structure that the ladder vertical plate is movably connected with the ladder panel; at least one controllable telescopic shaft which is driven by a power device is connected with the ladder plate; the expansion and contraction of the telescopic shaft can cause a ladder surface formed by the ladder vertical plate and the ladder panel deform into a step-shaped ladder surface and a bevel-shaped ladder surface. On the occasion of actual application, the ladder vertical plate is hinged with the ladder panel; the power device can use the modes of a motor, an air pump, hydraulic pressure, etc. In the utility model, a ladder surface forms the adjustable step-shaped ladder surface and the bevel-shaped ladder surface by changing the existing fixed type step-shaped ladder into an adjustable type ladder. When the bevel-shaped ladder surface is used, the problem for disabled persons and passengers who have hand-pulled traveling trolleys and bags with wheels to get on and get off is solved.

Description

The adjustable ladder that supplies passenger getting on/off to use

Affiliated technical field

The utility model belongs to a kind of step-like ladder, relates in particular to a kind of relevantly with the vehicle, makes things convenient for the passenger up and down such as the step ladder of the vehicle such as bus, train or aircraft.

Background technology

Before the utility model is made, existing and the vehicle in the public technology, form the ladder of structure as supporting use such as bus, train or aircraft or as it, be step as the shape of the cascaded surface of getting on or off the bus for people, for the passenger up and down the vehicle passage is provided.Its form has the branch as the component part setting of the vehicle or independent setting, and the ladder of aircraft is exactly independent be provided with a kind of.

No matter be independent be provided with or as the annex setting, this step ladder is made troubles to the part passenger getting on/off sometimes: the passenger who uses the travelling dolly, has wheel case and bag belongings to get on or off the bus, must mention article and get on or off the bus, the passenger will feel very inconvenient when heavier as article; The disabled person hopes especially and draws back that wheelchair and people can only be carried on by other people and carry off.At present, along with improving constantly of social civilization degree, a lot of cities are according to nation-building portion " urban highway and building accessibility designs standard " requirement, accessibility designs and construction on urban road construction and passage, have all been carried out, so as the vehicle that move get on or off the bus passage also should be as early as possible with reference to the requirement of the Ministry of Construction, carry out accessibility designs and manufacturing, to satisfy the trip that the disabled person waits the specific demand crowd.

Summary of the invention

For overcoming the above-mentioned deficiency of prior art, the utility model provides a kind of adjustable ladder that supplies passenger getting on/off to use of novel structure, it can be independently to be similar to the portable ladder that aircraft is used, also can be the adjustable ladder that is fixedly installed on bus, the train as on-board and off-board, it have solved the disabled person well and has waited the problem of getting on or off the bus that the specific demand crowd is arranged.

For achieving the above object, the utility model has adopted following technical scheme: the structure of the adjustable ladder that this confession passenger getting on/off is used comprises stepped plate, stepped plate is made of ladder riser and ladder panel, its structural feature is: ladder riser and ladder panel are for flexibly connecting, have at least a controlled telescopic shaft that drives by engine installation to be connected with stepped plate, the flexible ladder riser and the formed cascaded surface of ladder panel of can causing of telescopic shaft changes shape, two kinds of shapes of step-like cascaded surface and inclined plane shape cascaded surface occur.

During concrete enforcement, be connected by hinge between ladder riser and ladder panel; Engine installation is an air pump, by stretching of air pump control telescopic shaft, or adopts hydraulic efficiency gear to control the flexible of telescopic shaft.

Beneficial effect: the utility model will have fixed step-like ladder now and change over adjustable ladder, make cascaded surface adjustable step-like cascaded surface and two kinds of shapes of cascaded surface of inclined plane shape occur, when using the inclined plane shape cascaded surface, solved the disabled person and pull the travelling dolly, roller box transportation adopt responsible crew system visitor's the problem of getting on or off the bus is arranged.

Description of drawings

Fig. 1 is the longitudinal plane structure scheme drawing of an embodiment of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing is routine by experiment the utility model is further elaborated.

Sequence number among Fig. 1 is represented respectively: engine installation 1, telescopic shaft 2, a hinge 3,

support beam

4,8,9, ground 5,

hinge

6,7, cabin floor 10,

ladder riser

11,12, ladder panel 13.

Fig. 1 shows the longitudinal plane structure of an embodiment of the utility model, and solid line represents that partly telescopic shaft 2 is in the state of not stretching out, and dotted portion is then opposite.Stepped plate is made of some ladder risers 11 and ladder panel 13, and the end limit, one side of a ladder riser of highest point and cabin floor 10 flexibly connect through hinge, then, successively ladder riser 11 and ladder panel 13 are coupled together by hinge 6,7.Ladder panel 13 outer ends of lowest part should be positioned at the compartment shell before telescopic shaft 2 is not flexible, so that the setting of car door.

Telescopic shaft 2 of fixed installation (certainly below stepped plate, length difference according to cascaded surface, also can consider to be provided with many telescopic shafts), this telescopic shaft 2 can be air-pump type or telescopic shafts such as fluid pressure type or electric machine control formula as forms such as propulsions source (because the engine installation of compositions such as air pump, hydraulic pressure or motor is common prior art, just be not described in detail at this), and a switch that is used to control air pump or hydraulic efficiency gear is set, be convenient to the operation of driver or bus attendant.The axle head of telescopic shaft 2 and one hinge 3 flexibly connect, and 3 of hinges are fastening with a ladder riser 11.Consider the firmness of cascaded surface, every ladder panel 13 bottoms a

support beam

4,8,9 is set, this support beam should be a roller bearing, and the axle two ends are fixed on the bearing, the friction force when sliding thereon to reduce ladder panel 13.Be provided with prompting piece, the piece symbol of advancing according to Ministry of Construction's standard on the cascaded surface, to make things convenient for the blind person to walk and to play anti-skidding effect.Height, length or the gradient as for ladder can be set according to the actual conditions of the vehicle.

During use, when telescopic shaft was in last extended configuration, whole cascaded surface was step shape (solid line is partly represented among Fig. 1).When the driver and conductor presses master cock, engine installation drives telescopic shaft and stretches forward, promotes a hinge 3, ladder riser 11 forward, is in a plane until ladder riser 11 and ladder panel 13, to form a slope for passenger getting on/off.The passenger is convenient can also to be provided with some handrails on ladder panel 13 in order to make.

The foregoing description is fit to be applied on the vehicle such as bus, train, and it becomes the component part that constitutes these class vehicle, for passenger getting on/off.If a kind of portable its design plan is also similar for passenger's adjustable ladder of usefulness up and down for aircraft provides, just telescopic shaft, support beam etc. is fixed on the frame of ladder and get final product, and be provided with one group in the frame bottom and move wheel, so that mobile.

Certainly, the ladder of this structure also can be designed to the goods ladder that handling goods is used, and also surely belongs to the protection domain of the art of this patent.
