Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to handrails installed in buildings, particularly in staircases, hallways, etc. of ordinary homes.

Conventionally, handrails made of a metal material or the like inserted into a structure have been made by inserting a resistor such as a wire into a line defined by the intersection of the neutral plane and the plane of symmetry of a structural body made of elastomer or plastic with a C-shaped cross section. There have been handrails for escalators and the like that are guided on rails carried by a fixed frame by embedding the structure to give it non-stretchability.

However, the structures used in the conventional escalators, etc. mentioned above cannot be bent or twisted to follow changes in the curves and unevenness of stairs, and the structures alone cannot maintain rigidity as handrails for buildings. It had the disadvantage that it was not possible.

The present invention has a core body made of metal, hard synthetic resin, semi-hard synthetic resin, etc. in the center of the fleshy part of the handrail main rod, which is made of a flexible material such as soft synthetic resin or rubber, and has a perfect circular cross section. In order to enable the handrail main rod to bend and twist, and to maintain its rigidity, it is embedded continuously during molding, so that it can be bent and twisted to follow the curves and uneven surfaces of the building wall. To provide a handrail for a building that can be attached with a bracket.

The structure of the present invention will be explained based on the embodiments shown in the attached drawings. 1 is a handrail main rod, which is made of a continuous shape from a flexible material such as soft vinyl chloride resin or rubber;
Its cross-sectional shape has a perfect circular shape so that it can be bent and twisted vertically and horizontally.

At the center of the fleshy part of the handrail main rod 1 and around it, a core body 2 with a circular cross section made of a relatively soft metal such as aluminum is formed by molding means such as co-extrusion with the handrail main rod 1. It is buried all together.

In addition, as shown in FIG. 3, the core body 2 is a core made of a hard or semi-hard synthetic resin with a relatively large diameter, except when a plurality of core bodies are used at the center of the fleshy part of the handrail main rod 1 and around it. The body 2 may be integrally implanted during molding to the extent that the bending of the handrail main rod 1 is not lost.

As described above, the handrail main rod 1, which is continuously formed and includes the core body 2 at its center, is bent and twisted to fit the curves and uneven parts of the stair wall 4, as shown in the first figure. 4 by an appropriate number of brackets 3.

The handrail main rod 1 is made into a continuous length or cut into lengths for one step, and shipped and transported in the form of a rod or rolled.

The present invention has the above configuration,
A core body made of metal, hard synthetic resin, semi-hard synthetic resin, etc. is placed in the center of the fleshy part of the handrail main rod having flexibility and a perfect circular cross-section to enable bending and twisting of the handrail main rod, and The main rod of the handrail can be bent at any position and regardless of the vertical or horizontal direction by integrally recessing the handrail to maintain its rigidity and following the curves and uneven surfaces of the stair wall of the building where the handrail is attached. , twisting, etc. are performed, and there is no need to partially cut the handrail main rod to create a gap or connect multiple handrail main rods with separate joint members, and it can be installed continuously on the stairs. This improves the beauty of the handrail itself and makes it easier to install it.

In addition, since the core body is integrally formed in the center of the fleshy part of the handrail main rod, it is possible to partially bend and twist the handrail, and at the same time, the handrail main rod can be attached with a bracket to prevent its deformation. is prevented,
The rigidity of the entire handrail can be increased.

[Brief explanation of the drawing]

Fig. 1 is a cross-sectional view showing an embodiment of the handrail for a building according to the present invention, showing the state of construction on a stair wall, Fig. 2 is a cross-sectional view of a handrail main rod having a core, and Fig. 3 is a cross-sectional view of a handrail main rod having a core body. It is a sectional view showing a modification. 1...handrail main rod, 2...core body, 3...bracket.

Claims (1)

[Claims] 1. A core body made of metal, hard synthetic resin, semi-hard synthetic resin, etc. is placed in the center of the fleshy part of the handrail main rod, which is made of a flexible material such as soft synthetic resin or rubber, and has a perfect circular cross section. In order to enable bending and twisting and maintain rigidity, the handrail main rod is embedded continuously in one piece during molding, and the handrail main rod is bent and twisted to follow the uneven surface of the building wall. A building handrail characterized by being attached with a bracket.
