Description

  The present invention relates to a decorative cover that covers the outer periphery of an insertion body such as an air conditioning pipe, a hot water supply pipe, or a cable that is arranged along a predetermined arrangement path.

  As a decorative cover, as shown in Patent Literatures 1 and 2, generally, a resin-made lower cover body in which side plates are integrally formed on both sides in the width direction of the bottom plate portion, and side plates on both sides in the width direction of the top plate portion. A resin upper cover body integrally formed with the upper cover body, and an engaging portion and an engaged member that can be engaged and disengaged at opposing portions of both side plate portions of the lower cover body and both side plate portions of the upper cover body. A decorative cover of a resin molded product in which a joint portion is formed is used.

  As a decorative cover for this type of resin molded product, in addition to a linear cover, a plurality of types of decorative covers made of injection molding are available, such as T-type joints, 90 ° elbows, branch joints, etc. This contributes to easier and more efficient cover construction.

  However, for example, at locations where the branch pipe is split into two branches from the air conditioning pipe, the size of the joint becomes very large, making it difficult to manufacture by the injection molding method, increasing capital investment, and the expected mass production quantity. Therefore, there is a problem that the manufacturing cost increases.

  For this reason, at the installation site where the size of the joint becomes large, a resin sheet such as hard vinyl chloride or polypropylene or a metal racking plate is bent into a cylindrical shape while covering the outer periphery of the insert. In addition, the side edges of the resin sheet or the racking plate that are bent into a cylindrical shape are joined to each other with a tape or an adhesive, or as shown in Patent Document 3, the resin sheet or the racking is used. The connecting member is fitted and joined to the engaging protrusion integrally formed on the outer surface of the both side edges of the plate from the cylindrical axis direction.

  Further, a deformable metal Kiza seat member having a substantially L-shaped cross-section is wound around both ends of the resin sheet or the racking plate that is bent into a cylindrical shape. Then, the wound annular star seat member and the cylindrical resin sheet or racking plate are joined with a tape or the like, and an opening through which the insertion body can be inserted appears at the center of the annular star seat member. A so-called racking method is adopted.
