Patent number: 10293670Abstract: In a vehicle molding attached to a vehicle body part, a clip, to attach a molding body onto a body-part edge portion, is provided with an insertion part, into which the body-part edge portion is inserted; an engaging portion configured to engage with an engagement-receiving portion, provided on the body-part edge portion in a state where the edge portion is inserted into the insertion part, whereby a relative movement is restricted in a removal direction; and a biaser which elastically deforms upon abutting against the body-part edge portion that is inserted into the insertion part, the biaser applying a force that engages the engaging portion with the engagement-receiving portion by a restorative force of the elastic deformation of the biaser. Accordingly, the vehicle molding can be securely and reliably attached at a proper position while having a simple structure.Type: GrantFiled: March 27, 2015Date of Patent: May 21, 2019Assignee: SHIROKI CORPORATIONInventors: Jun Makita, Takanori Suzuki

Patent number: 10160296Abstract: An object is to provide a sash coupling structure and a method for sash coupling that ensures omission of the process. The sash coupling structure is made such that on a door frame constituted of a column and an upper sash, a coupling cross-sectional surface of the column and a coupling cross-sectional surface of the upper sash are butted together. The column is constituted of a channel member and an inner member. The channel member and the inner member include adhering portions coupled one another along a longitudinal direction. The inner member is plated. A non-adhering portion, which faces a non-not-yet-adhering portion of the inner member, is formed on the channel member at a butted coupling portion.Type: GrantFiled: May 22, 2015Date of Patent: December 25, 2018Assignee: SHIROKI CORPORATIONInventors: Jun Makita, Yu Okumura, Hiroshi Enoki
