Description

  The present invention relates to a metal handrail jacket, and more particularly to a metal handrail jacket that is applied to the surface of an existing metal handrail.

  In general, handrails installed outdoors such as public facilities are often made of metal such as stainless steel for durability.

  Such metal handrails have a large change in surface temperature due to temperature and solar radiation, and are hot in summer and cold in winter. Therefore, there are users who hesitate to touch, and the original purpose of the handrail is not fulfilled.

  In order to achieve the original purpose of handrails, a means of covering the surface of a metal handrail with a synthetic resin layer can be considered, but when applied to existing handrails, handrails must be replaced. There is such a concern.

  Conventionally, a synthetic resin cover is attached to an existing handrail. In a metal handrail supported by a plurality of support portions, an elastic material such as a cylindrical rubber or an elastomer resin is provided around the handrail between the support portions. One that attaches a deformable cover is known (for example, see Patent Document 1).

  In the one disclosed in Patent Document 1, the opening width of the side opening provided in the cover is opened until it becomes larger than the outer diameter of the handrail, the handrail is inserted, and then returned by elastic deformation to the entire circumference of the handrail. In order to cover the cover and prevent the cover from falling off or to be securely attached, the end faces of the side opening portions of the cover are joined by uneven fitting or adhesion.
