Description

[Detailed Description of the Invention] The present invention provides a stair handrail that can be used effectively over the entire width of the staircase and is excellent in construction and economy.

That is, as shown in FIG. 3A, the handrail for stairs is generally provided so as to protrude from the wall surface W via the support member 5, so that the width (inner dimension) of the stairs is This is substantially reduced by the amount of protrusion of the handrail 6, and this is a major problem in residential buildings where the width of the stairs is restricted and standardized due to various circumstances, such as unit-type housing.

For this reason, it has been proposed that a recess be formed in the wall located along the staircase, and a handrail 6 be attached to the recess through a support member 5, as shown in the opening in Figure 3. However, in this stair handrail as well, in order to ensure the original function of the handrail 6, it is necessary to attach the supporting member 5 sufficiently firmly to the recessed part of the wall, which reduces the material cost. However, the construction costs tend to be high, the surface finishing of the wall body and the installation of the handrail 6 are performed separately, and the workability is poor and the construction tends to be expensive.

The stair handrail of the present invention was developed in view of the current situation, and examples thereof will be described below based on the drawings.

That is, as shown in FIGS. 1 and 2, a recessed portion 3 in the wall thickness direction is formed at a position corresponding to the height of the handrail of a wall 2 located along a staircase 1 in a Units I type house, etc. The handrail is formed parallel to the slope of the staircase, and the lower edge 4 of the recessed part 3 projects upwardly than the bottom surface on the innermost side of the recessed part.

In this way, the stair handrail of the present invention utilizes the lower edge 4 of the recessed portion 3 itself as a handrail, so the stair handrail of the present invention
In addition to being able to effectively use the entire width of the handrail, since the lower edge 4, which is a part of the strong wall 2, is used, it is easy to obtain sufficient strength as a handrail, and the supporting member 5 as mentioned above can be easily used. Since no material is used, the material cost is low, the handrail can be formed at the same time as the recessed part 3 of the wall body 2 is formed, and the workability is good and it is very economical.

Although not shown, the present invention can also be implemented by attaching a resin sheet or the like that is comfortable to the touch to the surface of the lower edge 4.
