  • Patent number: 10386886
    Abstract: A portable information device is capable of securing the appearance quality and the durability of products while having a foldable configuration. The portable information device has a backbone member provided throughout and between the inner surface of one edge portion of a first chassis member and the inner surface of one edge portion of a second chassis member so as to cover a gap between the one edge portion of the first chassis member and the one edge portion of the second chassis member connected by a hinge mechanism. The backbone member is provided to the inner surface of the one edge portion of the first chassis member so as to be slidable in an X direction from the second chassis member to the first chassis member along the inner surface, and is non-slidably fixed to the inner surface of the one edge portion of the second chassis member.

  • Patent number: 10345862
    Abstract: A support for an electronic device is able to prevent a chassis from wobbling without coming off from the chassis. The support is attached to an opening of the chassis of the electronic device. The support includes a base portion positioned on an exterior surface side of the chassis so as to overlap the opening, a retaining portion that is positioned on an inner surface side of the chassis and provided so that the opening is able to retain the retaining portion with or without interposing a separate member, a connecting portion that connects the base portion and the retaining portion with each other and is inserted through the opening, and an elastic protruding portion provided on the base portion and structures a contact point with the exterior surface of the chassis. The base portion is structured so as to support the chassis through the elastic protruding portion.

  • Patent number: 10088873
    Abstract: A chassis structure is disclosed. A chassis includes a plate-like body in which a foam layer is located between a pair of fiber-reinforced resin plates, and a frame body formed of a thermoplastic resin and joined to a peripheral portion of the plate-like body. The plate-like body is configured such that its peripheral portion is formed by an ear-like joint portion where the pair of fiber-reinforced resin plates are joined together without the foam layer located therebetween, thereby sealing the foam layer inside the pair of fiber-reinforced resin plates. The frame body is joined to the plate-like body in a state where the frame body is in contact with the joint portion.
