Abstract

PURPOSE: To provide a handrail section, which has excellent appearance design properties and is clasped easily without sliding, on which there is no cold feeling and in which a surface is smoothed and is difficult to be fouled, by covering the external surface of a cylindrical core material, in which projecting sections are formed to a surface, with a cylindrical elastic material with a skin layer. CONSTITUTION: A handrail member 1 is formed of a cylindrical core material 2 and a cylindrical elastic material 3. Projecting sections 2a are arrayed and shaped in the circumferential direction of the external surface of the core material 2. The elastic material 3 is formed of a foamed layer 3a and a skin layer 3b. When the elastic material 3 is pushed from the external surface of the elastic material 3, the foamed layer 3a is sunk. Consequently, when the elastic material 3 is pushed by the bulb of a finger, the elastic material 3 is sunk along the shape of the finger, thus preventing sliding. Accordingly, the handrail member 1 is grasped easily without sliding, has no cold feeling, a surface thereof is smoothed and fouling is difficult to adhere, and can be used safely from children to the aged.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail member for a handrail provided in a building or equipment.

[0002]

2. Description of the Related Art Conventionally, handrails made of wood or metal pipe have been generally used for handrails provided in buildings and equipment, but in order to improve the appearance and the grip,
Various materials and structures have been devised. To give a few examples, metal pipes coated with synthetic resin, those with circular cross-sections, ellipses, prisms, etc. Some are embossed or have irregularities. In addition to these, there are those that improve the feel when gripped, have surface flocking to eliminate coldness, and have urethane foam coated. For example, Japanese Utility Model Laid-Open No. 6-58030 discloses a handrail member provided with a plurality of concave streaks in a circumferential direction on a rod-shaped outer surface so that a ball of a finger can be accommodated when held by a hand.

[0003]

However, in the case of a handrail or a handrail member having an uneven surface as described in Japanese Utility Model Laid-Open No. 6-58030, it is difficult to grip and prevent slippage. Is excellent, but it is difficult to say that it is easy to get dust and dirt on the uneven portion, it is easy to get dirty, and it is difficult to clean, and the appearance is also excellent.

The present invention has been made by paying attention to such conventional problems. The purpose of the present invention is to solve the above problems, excellent appearance design, and easy grip without slipping. A handrail member that does not feel cold, has a smooth surface, and is not easily soiled.

[0005]

In the handrail member according to the present invention, the outer surface of a tubular core material having a convex portion on its surface is covered with a tubular elastic material having a skin layer. It is characterized by

In the handrail member according to a second aspect of the present invention, the outer surface of the tubular core material having a convex portion on the surface is covered with a tubular elastic material having a skin layer, and the outer surface of the core material and the elastic material are covered. It is characterized in that a space is provided between the inner surface and the inner surface.

It is characterized in that it is configured to have irregularities.

As the material of the core material, in addition to metal such as stainless steel material and aluminum material, synthetic resin, wood and the like are preferably used.
The shape of the unevenness of the core material or the elastic material and the pitch thereof can be set relatively freely, but it is preferable that the shape is provided so that it is pressed and retracted when grasped and conforms to the shape of the finger.
Furthermore, the method of disposing the unevenness is preferably linear, annular, spiral, or zigzag. In addition, the cross-sectional shape of the core material can be relatively freely selected such as polygonal shape as well as circular or elliptical shape.

As the material of the elastic material on the surface, synthetic rubber or synthetic resin is preferably used, and the foaming ratio is lowered only in the convex portion,
Foams such as polyethylene resin, vinyl chloride resin, and polyurethane resin are suitable. In addition, a skin layer may be formed on the surface, and the skin layer may be embossed so as to have a non-slip design and a design.

If the thickness of the elastic material on the surface is too thick, it will not be retracted into the shape of a finger when grasped by a hand, so it is preferable to set it in relation to the hardness of the elastic material.

The handrail member of the present invention has a wide range of uses, and is used for general houses such as bathrooms, toilets, dressing rooms, corridors and stairs, as well as general vehicles such as public facilities, buses, trains, ships and airplanes.
In particular, it is effective when used as a handrail in bathrooms, washrooms, and general public facilities that use water and soap.

The handrail member of the present invention is manufactured by a method of separately molding a core material and an elastic material and integrating them in a post process, and a method of simultaneously molding using a twin-screw or three-screw extruder. be able to. Further, it is also possible to carry out a method in which the processing of the core material and the convex portion on the outer side are simultaneously advanced to coat the surface with the elastic material. In this case, the elastic material can be molded by extrusion molding or by seamlessly processing a sheet-shaped elastic material into a tubular shape.
