DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parting material used at a boundary of an interior material such as a floor material and a wall material of a building.

[0002]

2. Description of the Related Art In recent years, wheelchairs,
In order to protect the wall surface and prevent dirt by contact with a stretcher, etc., floor materials are being built up to the wall surface and construction is being carried out. , Hard plastic, etc.
Sealing material is used.

[Problems to be solved by the invention]

[0003] However, since the parting material conventionally used is made of a hard material, there is a danger of being injured if a person falls down or hits it unexpectedly. There is a gap between the parting material and garbage, and the appearance is bad. In addition, although there is no gap between the wall and the wall surface when the sealing material is used, there is a problem that the floor material raised on the wall surface is easily peeled off or hangs down by its own weight, so that the workability is poor and the appearance is not good.

[0004] The present invention has been made in view of such circumstances, and provides a parting material having good workability and good appearance without fear of injury.

[0005]

In order to solve the above-mentioned problems, the present invention has been made to solve the problem by forming a decorative cover piece on the upper front surface of a rising piece with a hard thermoplastic resin so as to form an insertion recess. A surface layer made of a soft thermoplastic resin is provided outside the cover piece, and a vertex made of the soft thermoplastic resin is provided at the top of the rising piece, and the tip is curved toward the wall surface side. And the lower part of the decorative cover piece is made of an elastic body made of a soft thermoplastic resin.

According to the above-mentioned means, the surface layer is soft while having strength, so that even if it collides due to overturning or the like, the surface layer can absorb the impact and the risk of injury is extremely reduced. Moreover, even if the wall surface has irregularities, the irregularities are absorbed by the soft velvet, and no gap is formed between the irregularities and the wall surfaces. Further, when the floor material rising on the wall surface is inserted into the insertion recess, even if the thickness of the floor material varies somewhat, the floor material can be sandwiched by elasticity.
