Description

  The present invention relates to a handrail member and a handrail used for a handrail installed in a building or the like.

Handrails are provided on the staircases and corridors inside and outside of various buildings, around sanitary equipment, and on the walls of bathrooms to ensure safety. Since such a handrail is directly touched by a large number of people, it tends to be unsanitary such as bacterial growth. In particular, in hospitals and elderly facilities, etc., bacteria attached to the handrails can cause indoor infection, so handrails carrying antibacterial agents and disinfectants, handrails carrying photocatalysts, etc. are disclosed. (For example, refer to Patent Document 1)
JP 2003-239490 A

  However, since antibacterial agents and bactericides have reduced antibacterial effects over time, it has been difficult to maintain the antibacterial and bactericidal effects for a long time. In addition, since photoactivity of photocatalyst decreases due to contamination, etc., it is difficult to maintain a constant and stable antibacterial and bactericidal effect for a long period of time, and it cannot be used in places where there is not enough light. There was a case.

  If the anti-bacterial and anti-bacterial functions are not available on the handrails, disinfecting parts by hand and periodically disinfecting the handrails by hand is very time-consuming. Could remain.

  The present invention has been made to solve the above-described problems, and it is an object of the present invention to provide a handrail member that can constantly obtain a high sterilizing effect over a long period of time.

  This invention solves the said subject with the handrail member characterized by having an electroconductive heat generating part.

  The handrail member of the present invention has a high heat sterilization performance because it can be heat sterilized by having a conductive heat generating portion that generates heat by electrical conduction. Further, since the sterilization performance does not deteriorate with time, stable sterilization performance can be realized over a long period of time.

  In addition, since antibacterial agents and photocatalysts are difficult to obtain their effects unless they are substantially exposed on the handrail surface, it may be difficult to achieve high sterilization performance. Therefore, a high bactericidal effect can be obtained.

The conductive paint may be applied by an appropriate method such as a spray method, a brush coating method, or a dipping method.

  The installation form of the conductive heat generating portion provided in the handrail member may be appropriately selected depending on the member and shape to be used, but since the sterilizing effect on the entire outer periphery of the handrail member is easily obtained, the handrail member It is preferable that it is provided in the shape along the outer periphery. Moreover, it does not need to be provided on the entire surface along the outer periphery.

  As the said form, the handrail member of the form by which the electroconductive heat generating layer which consists of electroconductive metal foil or an electroconductive coating material was provided in the outer periphery of the rod-shaped core material can be illustrated preferably, for example.
