  • Patent number: 10549615
    Abstract: Disclosed is a structure of a cover which allows a first link 25 to be pivotally coupled to a front roof panel via a stepped rivet 27, and a cover 31 to be pivotally coupled to the stepped rivet 27 via a first stepped screw 33. An overhang portion 27e of the stepped rivet 27 is joined to the front roof panel with a periphery of a front attachment hole 23c of the front roof panel being sandwiched between the overhang portion 27e and a large diameter portion 27c inserted in an insertion hole 25a of the first link 25 to pivotally support the first link 25. The first stepped screw 33 has a threaded portion 33d fastened into a fastening hole 27f of the stepped rivet 27, and a base end 33c inserted in a first through hole 31b of the cover 31 to pivotally support the cover 31.

  • Patent number: 10035409
    Abstract: There provided an openable roof, a link mechanism foldably supporting the openable roof, and a drive device to drive a drive link of a link mechanism. The drive device comprises a drive unit including a drive gear connected to a drive motor, a driven gear provided at the drive link, and an intermediate gear engaging with the drive gear and the driven gear. The drive unit is located at a lower level than a beltline of the vehicle body, the driven-gear pivotal portion is located at a higher level than the beltline, and the intermediate gear is located at a specified level such that the intermediate gear overlaps the beltline in a side view.

  • Patent number: 4859636
    Abstract: The invention relates to a method of strengthening a glass article formed of sheet glass produced by the float process. The strengthening method includes a known ion exchange treatment to replace alkali metal ions in the surface layers of the glass with, e.g., alkali metal ions larger in ionic radius such as potassium ions. To prevent warping of the glass article during the ion exchange treatment by the influence of a metal element such as tin used as the molten metal in the float process and diffused into one surface of the sheet glass, the glass article is pretreated by contacting at least said surface with an external source of sodium ions and/or lithium ions and heating the glass article together with the external source of the alkali metal ions at 350.degree.-650.degree. C. for 0.01-100 hr. The pretreatment is neither preceded nor followed by grinding or polishing of said surface of the glass.
