Description

A handrail having a structure that improves the usability of pedestrians.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail, and more particularly, it relates to a handrail, which improves the structure of a handrail installed in a stairway or a corridor of a building to allow all pedestrians to conveniently use it regardless of the physical condition of the pedestrian, The handrail has a structure that can be considered to be suitable for the physical condition of the weak person who is a socially weak person, the handicapped person and children, and which can improve the usability of the pedestrian so as to reduce the construction cost by improving the convenience of construction .

Generally, a staircase is a single-type passage connecting two floor surfaces having different heights in order to connect each floor when building a multi-storey building. As the modernization of the city and the high-rise of the city are spreading, It became a facility.

These stairs have various structures and forms ranging from large-scale public buildings to small-scale houses, and all of them are installed for the purpose of making everyone safe and comfortable. In addition, on one side or both sides of the staircase, there is provided a handrail which can be supported when the pedestrian is moved so as to prevent a fall of the pedestrian.

In this case, the structure of the handrail is composed of a plurality of supports fixed on a floor or a wall, and a handrail connecting the support to the support.

Here, the handrail is a means for allowing a pedestrian to hold and walk on the pedestrian. In recent years, a stairway of a general building, a patient or a senior citizen who is uncomfortable in walking by being installed on one side or both sides of a corridor of a hospital or a nursing facility, So that the user can walk safely.

As a representative example of the handrail, a "wall-mounted handrail" registered in Korean Registered Utility Model No. 20-0446595 is shown in FIG.

1, the utility model registration No. 0446595 includes a mounting portion 11 to be installed on a wall, a coupling portion 12 connected to the mounting portion 11 and having a fastening hole which is bent upward and is a circular hole, A connection bracket 10 including a mounting cover 13 covering the mounting portion 11;

The first and second horizontal portions 21 and 22 are spaced apart from each other and are connected to the first and second horizontal portions 21 and 22.
