Description

  The present invention relates to a corner cushion, and more particularly to a corner cushion that receives outer sides of the corners of a frame that are orthogonal to each other, and more particularly to a corner cushion that is suitable for use in a corner portion of a fitting such as a sash.

  When transporting and storing a sash joinery, the corner portion where the structural members intersect, particularly at right angles to it, is liable to be damaged by coming into contact with other articles. Therefore, for example, as disclosed in Japanese Patent Application Laid-Open No. 2003-261165, a corner protective material that can protect a corner portion of an article or a fitting with a simple structure has been proposed. The corner protective material has an end side portion applied to two adjacent sides of the corner portion of the article, and a side piece applied to the front and rear surfaces of the corner portion of the article. The corner portion of the article is accommodated in the concave portion partitioned by one portion, and a plurality of reinforcing support portions bent in a cross-sectional mountain shape on the inner surface of at least one end side portion so that the ridge portion extends along the longitudinal direction. It is provided.

  Such a corner protector is folded in a chevron cross section on the inner surface of the short side so as to receive a sash part having fins protruding from the outer frame of the frame wall, particularly for mounting on the building frame. Although a plurality of bent reinforcing support pieces are provided so that the ridges extend along the longitudinal direction, the area that receives the frame of the sash is received at the apex of the triangle, thereby reducing the area of the receiving surface. There exists a fault which the reinforcement support piece part bent in the cross-sectional mountain shape tends to be crushed. Further, when the support piece portion is crushed, the fins of the frame body may come into contact with other articles, which may cause deformation of the fins.
