Abstract
Abstract Molding made of high polymer material, formed as a hollow molding body from extrusion and installed to a substance through adhesive means on a rear surface of the molding body, characterized in that plural pieces of a projecting pillar are arranged to be projecting from an upper wall and a bottom wall of a hollow portion of the body in the longitudinal direction. When installing the molding to a substance, pressing force applied to the molding body is almost equally transmitted to the whole bottom surface of the body. The molding can restore adhesive force declined with the passage of time to the original state by applying pressing force from the molding surface even after installing to the substance as well as can perform adhesive function of the adhesive layer sufficiently.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
Molding made of high polymer material, formed as a hollow molding body from extrusion for installation on a substance by adhesive means on a rear surface of said molding body, characterized in that plural pieces of a projecting pillar are arranged to be projecting from an upper wall and a bottom wall of a hollow portion of said molding body in the longitudinal direction, each of said pillars being of insufficient length to communicate with said opposed wall and pillar to define a continuous transverse hollow portion when said molding is free from a pushing force applied to said molding, and each of said pillars being sufficiently long to make contact with opposed wall and pillar when a pushing force is applied to said molding to substantially evenly apply said force to said adhesive.
Claim 2
Dependent Claim
134 words
Molding made of high polymer material, formed as a hollow molding body from extrusion for installation on a substance by adhesive means on a rear surface of said molding body, characterized in that plural pieces of a projecting pillar are arranged to be projecting from an upper wall and a bottom wall of a hollow portion of said molding body in the longitudinal direction, each of said pillars being of insufficient length to communicate with said opposed wall and pillar to define a continuous transverse hollow portion when said molding is free from a pushing force applied to said molding, and each of said pillars being sufficiently long to make contact with opposed wall and pillar when a pushing force is applied to said molding to substantially evenly apply said force to said adhesive.
Claim 3
Dependent Claim
60 words
Molding according to claim 1, characterized in that each of the top parts of plural pieces of the projecting pillar projecting from the upper wall and the bottom wall of the hollow portion of the molding body in the longitudinal direction on one side is constituted to be in a valley portion between the projecting pillars on the other side.
Claim 4
Dependent Claim
59 words
Molding according to claim 1, characterized in that plural pieces of the projecting pillar projecting from the upper wall and the bottom wall of the hollow portion of the molding body in the longitudinal direction are oppositely arranged from both sides and each top of the projecting pillars is constituted to be adjacent to or communicating with each other.
Claim 5
Dependent Claim
62 words
Molding according to claims 1, 2 or 3, characterized in that providing the number of plural pieces of the projecting pillar projecting from the upper wall and the bottom wall of the hollow portion of the molding body in the longitudinal direction on one side is set "n", that of the projecting pillar on the other side shall be "n" or "n-1".
Claim 6
Dependent Claim
67 words
Molding according to claim 2, characterized in that each of the top ends of plural pieces of the projecting pillar projecting from the upper wall and the bottom wall of the hollow portion of the molding body in the longitudinal direction on one side is arranged to be adjacent to or communicating with that of the projecting pillar on the other side or the inside wall thereof.
