RU192861U1 - BUILDING EVACUATION STAIRCASE - Google Patents

Abstract

The staircase for evacuation from buildings refers to stairs attached to stationary structures, to enable emergency evacuation from buildings. It contains two side racks connected by steps, hinges, providing its rotation around the axis to bring it into the lowered and raised position. The side pillars are hinged to two vertical support pillars attached to the wall from the outside of the building in the window opening using brackets. Side racks are made in the form of straight pipes, turning into the shape of arcs that make up a circle, and contain latches for holding the stairs in a raised state and slots for the movement of latches. The brackets contain a hole for fixing the latches. The staircase for evacuation from buildings involves the use of windows on the first floors of buildings and allows you to freely evacuate, which reduces the time of evacuation.

Description

The utility model relates to stairs attached to fixed structures to enable emergency evacuation of buildings.

An evacuation ladder is known, including steps connected by ends to rope ropes fixed at one end by an emphasis, the emphasis is made in the form of plates with holes for attaching to a building wall and with ears to hold the ends of the ropes [Russian Patent No. 17190, application filing date 03.20.2001 g.].

The disadvantages of the analogue include the fact that the descent of people using a suspended staircase is not completely safe, especially for children and the elderly.

The closest technical solution to the claimed utility model is a vehicle ladder containing two side racks interconnected by steps, as well as hinges providing its rotation around the axis to bring it into transport and working position, as well as a latch to hold the stairs in transport position . [Russian Patent No. 171533, filing date 02.11.2016].

This utility model relates to vehicle stairs, and can only be used in the doorway of a vehicle, therefore, has limited use, which is a disadvantage of this utility model.

Ensuring safe evacuation largely depends on timeliness and unhinderedness, especially in child care facilities. A large flow of children, the congestion of children at the exit doors, not always a serious attitude to what is happening, involves an increase in the actual time of evacuation. The technical task is to create a ladder for evacuation from buildings, providing the possibility of effective evacuation, suggesting a reduction in the actual time of evacuation.

The technical result is to reduce the time of evacuation and the ability to evacuate without hindrance.

круга. Боковые стойки содержат шпингалеты и прорези для движения шпингалетов; кронштейны содержат отверстия для фиксации шпингалетов.The technical result is achieved by the fact that the side posts are hinged with two supporting vertical posts, mounted on the wall from the outside of the building in the window opening with brackets, the side posts are made in the form of straight pipes turning into the shape of arcs, constituting

circle. Side racks contain latches and slots for the movement of latches; the brackets contain holes for fixing the latches.

The utility model is illustrated by the drawings of FIG. 1-4, where in FIG. 1 is a general view of the stairs in the raised and lowered position, in FIG. 2 is a side view of the ladder in the raised and lowered position, in FIG. 3 is a front view of the ladder in the raised and lowered positions, FIG. 4 kind of fixing of a latch.

Consider the implementation of a ladder for evacuation from buildings:

1 - side racks

2 - steps

3-hinges

4 - supporting vertical racks

5 - brackets

6 - latches

7 - slots for movement of latches

8 - holes for fixing the latches

9 - window opening

круга. Боковые стойки содержат шпингалеты 6 и прорези 7 для движения шпингалетов. Кронштейны содержат отверстия для фиксации шпингалетов 8.The staircase contains two side posts 1, interconnected by steps 2. Side posts 1 by hinges 3 connected to supporting vertical posts 4, which are attached to the wall from the outside of the building in the window opening 9 using brackets 5. Side posts 1 are made in the form of straight pipes transforming into the shape of arcs, constituting

circle. Side racks contain latches 6 and slots 7 for movement of latches. The brackets contain holes for fixing the latches 8.

The inventive device operates as follows: when a fire occurs, open the window, slide the latches 5, which keep the ladder in the raised state, and lower the ladder to the lowered position, allowing people to exit the building. The rotation of the ladder around the axis to bring it into a lowered position is provided by hinges 3 connected to two vertical supporting posts 4.

круга. Форма дуг позволяет спускаться лицом по ходу движения, перемещение не требует наличия поручней, что ускоряет выход людей из здания.People exit the building by steps 2 of two side posts 1, made in the form of straight pipes, turning into the shape of arcs, constituting

circle. The shape of the arches allows you to descend face in the direction of travel, moving does not require the presence of handrails, which accelerates the exit of people from the building.

After evacuation, the ladder is brought into an elevated position and fixed with latches in the holes of 8 brackets 5.

круга.In the raised position, the ladder forms a window-sill visor, since the side racks connected to each other by the steps of the ladder are made in the form of straight pipes turning into the shape of arcs, constituting

circle.

The staircase for evacuation from buildings involves the use of windows on the first floors of buildings and allows you to freely evacuate, which reduces the actual time of evacuation. Thus, the claimed utility model ensures the achievement of a technical result.

Claims (1)
