a stair ramp

Abstract

The invention provides a staircase ramp, which belongs to a ramp used for upward or downward towing of draw-bar cases and bags and combination with a staircase. A walking region is arranged between the two ramps; and people walk in the walking region when towing the draw-bar cases and bags. The staircase ramp provided by the invention has the advantages that pedestrians pulling the draw-bar cases and bags can conveniently go upstairs or downstairs, so that the force exerted on the draw-bar cases and bags by people and the gravity of the draw-bar cases and bags are simultaneously exerted on the longitudinal vertical cross section of the corresponding ramp; and the draw-bar cases and bags can be easily controlled to be linearly and upwards towed or linearly and downwards towed along the ramp. Baffle strips are arranged in connecting positions of the ramps and the staircase and the two ends of the walking region; and the draw-bar cases and bags are prevented from sliding and falling off from the ramp during the upward or downward moving. The invention also provides the staircase ramp with an anti-slip facility. An anti-slip structure consists of a plurality of half-water-drop structures in uniform distribution, wherein each half-water-drop structure comprises arc-shaped circular arc sections and concave circular arc sections in end-to-end connection. The anti-slip structure has the advantage that the probability that the cases and bags fall out from the hand of people and the potential danger that the cases and bags bruise the pedestrians are greatly reduced.

Description

technical field [0001] The invention relates to a stair ramp, in particular to a ramp for dragging a trolley case up and down and combined with a staircase. Background technique [0002] In railway stations, long-distance bus stations, subway stations and other places, it is necessary to pass through some steps. For the convenience of pedestrians carrying trolley bags to go up and down the stairs, ramps are provided on both sides of the steps, and escalators are also provided. Although escalators are more convenient for pedestrians with trolley bags, the installation of escalators is limited by funds, environment, etc., and consumes a lot of energy, so not every place is suitable for installation. [0003] At present, the existing stair ramps are mainly divided into two types according to the location: one is distributed on both sides of the entire staircase, such as Figure 1a and Figure 1b As shown, the stair ramps are distributed on both sides for separate ascending and...

Problems solved by technology

In the existing two kinds of anti-skid structures, because the stair ramp has a larger slope, the elastic force generated by the circular wheels on which these two anti-skid structures are placed on the figure will often not pass through the center of gravity of the wheels ( That is, the center of the circle), so the force acting on the wheel has a certain moment, which will promote the rotation of the wheel, and it cannot play the role of anti-skid

Moreover, if the pedestrian pulling the luggage accidentally leaves the heavy luggage, the greater gravity will have a greater potential to injure the pedestrian
