DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail device in which handrail bars are vertically and horizontally mounted and fixed to a wall surface of a bathroom or the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 6, there is known a handrail device in which a handrail bar member 26 is vertically and horizontally mounted and fixed to a wall surface 1 of a bathroom or the like. In this case, the vertical handrail bar 5 and the horizontal handrail bar 7 are integrated into
It is formed as a handrail bar material 26 bent in a letter shape.
The handrail bar member 26 is formed of a stainless steel pipe, and the protrusions 27 protruding from the mounting base 2a are respectively fitted and connected to the pipe openings at both ends thereof, so that the two mounting bases 2a are formed. Is fixed to the wall surface 1. Also, in the middle part of the handrail bar member 26, a mounting base 2b for fitting and supporting the vertical handrail bar member 5 is attached and fixed to the wall surface 1.

Accordingly, in this case, the substantially L-shaped handrail bar members 26 are attached to the mounting bases 2a and 2b at both ends and a middle portion thereof, respectively.
And is stably fixed to the wall surface 1.
Therefore, when going in and out of the bathtub in the bathroom, approximately L
The vertical handrail bar material 5 or the horizontal handrail bar material 7 of the character-shaped handrail bar material 26 can be selectively held by hand to support the body, and the same movement can be performed easily and safely.

[0004]

However, in the above-mentioned prior art, the vertical handrail bar 5 located at a position deviated from the corner of the substantially L-shaped handrail bar 26 has the following disadvantages.
Since it is fixed to the wall 1 by the mounting base 2b, the horizontal handrail bar 7 is easily deformed by a tensile force or the like, and an excessive stress is applied to the mounting base 2b, and the mounting base 2b is stabilized by fixing. However, there is a problem that the above-mentioned supporting strength cannot be obtained. Also, since it is difficult to change the length of the handrail bar material 26 integrally formed in a substantially L-shape with a stainless steel pipe at a construction site, it is necessary to cope with various construction forms. There was also a problem that it was not possible.

[0005] The present invention has been invented in order to solve all of the problems in the above-mentioned prior art, that is, the problem is that it is attached and fixed to a wall surface with stable supporting strength and can be easily applied to various construction forms.

By fitting the cut pipe opening to the vertical joint protrusion or the horizontal joint protrusion of one mounting base, it is possible to easily cope with various construction forms even at the construction site.

The handrail device according to a second aspect of the present invention is the handrail device according to the first aspect, wherein a mounting base is integrally formed on each of an upper end of the vertical handrail bar and one side end of the horizontal handrail bar. It is characterized in that both mounting bases are attached and fixed to a wall surface, respectively.

Therefore, in this case, in particular, the mounting bases formed integrally with the upper end of the vertical handrail bar material and one side end of the horizontal handrail bar material are fixed to the wall surfaces, respectively. The upper end and one side end of the horizontal handrail bar material are directly attached and fixed to the wall surface and supported, so that the mounting work on the wall surface is facilitated and the supporting strength can be reliably obtained.

According to a third aspect of the present invention, in the handrail device according to the second aspect, the vertical handrail bar material and the horizontal handrail bar material are each formed of a synthetic resin integrally with the mounting base. It is characterized by.

Therefore, in this case, in particular, the vertical handrail bar material and the horizontal handrail bar material are each easily formed integrally with the mounting base with synthetic resin. The lower end or the other end of the horizontal railing bar is easily cut, so that the length can be easily changed.

A handrail device according to a fourth aspect of the present invention is the handrail device according to any one of the first to third aspects, wherein the lower end of the vertical handrail bar material and the other side of the horizontal handrail bar material. A cover member for covering the opening edge of each of the two pipe openings at the end is provided, and the two pipe openings are fitted and connected to the vertical joint convex portion and the horizontal joint convex portion via the cover material.

Therefore, in this case, especially when the lower end of the vertical handrail bar material or the other end of the horizontal handrail bar material is cut and removed, the cut edges of both cut pipe openings are attached to the cover. Since each can be covered with a material,
By fitting and connecting the two pipe openings to the vertical joint protrusion and the horizontal joint protrusion through the cover material, the finished appearance of the connection portion can be stored in a good appearance.
