Embodiment Construction

[0009] The present invention will be further elaborated below through experimental examples in conjunction with the accompanying drawings.

[0010] figure 1 The sequence numbers in represent respectively: power unit 1, telescopic shaft 2, support hinge 3, support beam 4,8,9, ground 5, hinge 6,7, compartment floor 10, ladder riser 11,12, ladder panel 13.

[0011] figure 1 The longitudinal section structure of an embodiment of the present invention is shown, the solid line part indicates that the telescopic shaft 2 is in a non-extended state, and the dotted line part is opposite. The step plate is composed of several step risers 11 and step panels 13, one end of the highest step riser is connected with the compartment floor 10 through hinges, and then the step risers 11 and the step panels 13 are connected by hinges 6 in turn. , 7 to connect. The outer end of the lowest step panel 13 should be positioned in the compartment shell before the expansion and contraction of the tel...

Abstract

The adjustable stairs for passengers to get on and off bus have the structure comprising horizontal stair boards and vertical stair boards, and feature the movable connection between horizontal stair boards and vertical stair boards and at least one extension shaft driven with power unit and connected with the stair boards to change the overall shape of the stairs between stairs and inclined plate. Specifically, the horizontal stair boards and vertical stair boards are hinged, and the power unit may be motor, air pump, hydraulic unit, etc. Change the stairs into one inclined plate makes it possible for the wheeled chair, wheeled case, etc. to get on and off bus conveniently.

Description

Technical field [0001] The invention belongs to a step-like ladder, and in particular relates to a step-like ladder related to vehicles, which is convenient for passengers to get on and off vehicles such as buses, trains or airplanes. Background technique [0002] Before the present invention is made, in the known public technology, existing and vehicle, as supporting the use such as bus, train or airplane or as the ladder of its composition structure, as the shape of the step surface for people getting on and off the bus, it is all step type, for Passengers get on and off the vehicle to provide access. Its form can be set as an integral part of the vehicle or set independently, and the ladder of the aircraft is a kind of independent set. [0003] Regardless of whether it is set independently or as an accessory, this kind of stepped ladder sometimes brings inconvenience to some passengers when getting on and off the bus: passengers who use travel carts and wheeled bags to c...
