Liftable anti-stepping device

Abstract

The invention relates to a public plate safety device, in particular to a lifting type tread-preventing device. The device comprises fixed supports, clamps, inner telescopic rods and a pair of handrail rods, wherein multiple inner telescopic rods are installed on each handrail rod and hinged to the fixed supports, the fixed supports and the clamps are fixed to the top of a stairway, the handrail rods are installed parallel to the stairway, the handrail rods and the inner telescopic rods are overturned to be attached to the top of the stairway when not used, and the handrail rods are clamped by the clamps. The device can be stored on the top of the stairway, the free height and appearance of the stairway are not affected, and the handrail rods can provide leverage points for escape crowd to main body balance after descending; meanwhile, the two handrail rods are combined with stair railings after descending, and crowd decentralization can be guided, so that people can be evacuated in order.

Description

technical field [0001] The invention relates to a public place safety device, in particular to a liftable anti-stomping device. Background technique [0002] The existing patent "Handle Type Stampede Prevention Staircase" (application number: 201110270393.4) ​​introduces a device that can prevent stampede accidents in emergency situations. It is provided with three suspension rods along the longitudinal direction of the stairs at the bottom of the stairs. , each suspension rod is equipped with a handle, and the vertical distance between each handle and the steps below is 1.7-1.9 meters. When pedestrians are about to fall, they can grab the upper handle to avoid stampede accidents caused by falls. occur. The disadvantages of this technology are mainly manifested in: (1) its design is to be fixedly suspended above the stairs at ordinary times, and the vertical distance between the handle and the steps below it is 1.7-1.9 meters, which will affect the passage of the crowd in n...

Problems solved by technology

The disadvantages of this technology are mainly manifested in: (1) its design is to be fixedly suspended above the stairs at ordinary times, and the vertical distance between the handle and the steps below it is 1.7-1.9 meters, which will affect the passage of the crowd in non-emergency situations, not only It affects the clearance height and appearance of the stair passage, and changes the structure and function of the building; (2) the handle is located near the top of the escaped crowd, and there is a certain distance between the handles, which cannot ensure that people who lose their balance can grasp the handle, which will affect the safety of the facility. Stampede effect, due to its design flaws in non-emergency situations, it is difficult to popularize and apply
