Description

  The present invention relates to a corner cushion, and more particularly to a corner cushion suitable for being used by being attached to a corner portion of a joinery such as a sash.

  For example, as disclosed in Japanese Patent Application Laid-Open No. 2003-261165, when storing or transporting a joinery made of a sash, the corner portion of the sash is in contact with other members and is damaged or deformed. In order to prevent this, corner protectors are installed. The corner protector has an end piece applied to two adjacent sides of the corner of the article, and a side piece applied to the front and rear surfaces of the corner of the article, and the end piece and the side piece. The corner portion of the article is accommodated in the concave portion partitioned by the portion, and a plurality of reinforcing support piece portions whose cross-section is bent in a mountain shape on the inner surface of at least one end piece portion so that the ridge portion is along the longitudinal direction. The present invention relates to a corner protector which is provided and can protect a corner portion of an article or joinery with a simple structure.

  Although such a corner protector can protect the corner portion of the sash, there is a drawback that when such a protector is attached to the sash, the corner portion of the sash easily falls off. Therefore, conventionally, such a protective device is fixed to the sash using a tape, a film, or the like. Therefore, there is a disadvantage that a means for fixing the protective equipment is required, which makes handling difficult.
