Patent number: 11970017Abstract: A badge has a print layer and a substrate that is a processed layer. The print layer is printed with a subject image in which a radial center point is defined as a center point of a radial representation. The substrate has a circular brushed surface that is subjected to circular processing. At least one of the print layer and the substrate is light transmissive. The print layer is laminated on the circular brushed surface side of the substrate such that the radial center point of the subject image and a circular processing center point that is a center point of the circular processing coincide with each other.Type: GrantFiled: May 19, 2023Date of Patent: April 30, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masami Ikuma, Simon Humphries, Hiroshi Tomita, Daiki Isogai
