Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling parting edge which is used at the end portion of a ceiling plate to make the appearance of the ceiling and the wall look beautiful, and more particularly to a ceiling parting edge suitable for use when the wall is curved.

[0002]

2. Description of the Related Art The applicant proposed a bendable ceiling parting edge in Japanese Utility Model Laid-Open No. 64-23537. When this is used for a curved wall, it is bent at the factory according to the site or drawings. It is not necessary, and it has been well received because it can be easily applied even when the measurement of curvature is complicated, such as when the wall is complicatedly curved or the ceiling is inclined. The conventional bendable ceiling parting edge is entirely made of soft plastic with the same hardness, or is entirely made of soft plastic with the same hardness and a thin metal strip-shaped core material is embedded in the vertical plate. There was something.

[0003]

Since the conventional foldable ceiling parting edge is made of soft plastic having the same hardness as the whole, it is easy to be deformed such as twisting because it is soft as a whole. It is necessary to correct the deformation such as this, and the horizontal back plate is attached to the ceiling base by adhering it, but the horizontal back plate deforms into a funyafunya and it hinders the adhesion work, which is inefficient.
There is a problem. In addition, although the vertical plate portion is embedded with a metal strip-shaped core material, the above problems are improved,
Is still present and has a new problem that the manufacturing cost will increase significantly.

[0004]

The present invention has been made to solve the above problems. That is, the present invention
The lower horizontal parting part, the upper horizontal backing plate part, and the vertical plate part that connects them have a substantially U-shaped side surface shape. In the edge, the horizontal parting part is made of soft plastic, the ceiling parting part characterized by forming the horizontal back plate part and the vertical plate part by hard plastic, and the lower horizontal parting part, the upper horizontal back plate part, The upper horizontal projections projecting to the opposite side of the horizontal back plate and the vertical plate connecting them have a substantially inverted U-shaped side surface shape, and the horizontal back plate is provided with a notch to be bendable. In the ceiling parting edge, the horizontal parting portion and the horizontal projecting portion are made of soft plastic, and the horizontal back plate part and the vertical plate part are made of hard plastic.

In the present invention, the difference between the hardness and the softness of plastics is relative, and the essence of the present invention resides in that plastic materials having different hardness are used together. Hard plastic has a hardness that does not cause deformation such as twisting, and soft plastic needs to have a hardness that allows bending easily, but in practice, the hardness of the hard plastic is about 95 to 110 degrees. About 75 to 89 degrees is suitable for soft plastic.

[0006]

In the present invention, with respect to the ceiling parting edge having a U-shaped side surface, the horizontal parting portion is made of soft plastic, and the horizontal back plate part and the vertical plate part are made of hard plastic. This is a vertical plate part to fold horizontally,
Also, paying attention to the fact that the horizontal back plate with notches has a small bending resistance and the horizontal parting part has a large bending resistance, and the vertical plate and the horizontal back plate are made of a harder material and twisted in the vertical direction. It has succeeded in preventing this deformation. Further, of course, this also prevents deformation of the horizontal back plate itself.

Regarding the ceiling parting edge having an inverted U-shape, the horizontal parting part and the horizontal projecting part are made of soft plastic, and the horizontal back plate part and the vertical plate part are made of hard plastic. This is because the vertical plate portion and the horizontal back plate portion having the cutout have a small bending resistance for bending in the horizontal direction, and a large bending resistance is applied to the horizontal parting portion and the horizontal protruding portion. .

If a double-sided tape is attached to the upper surface of the horizontal back plate portion, the double-sided tape can be immediately adhered to the ceiling base by peeling off the protective paper of the double-sided tape during construction, and the construction efficiency is remarkably improved.
