Abstract: A portable keyboard comprises a flexible substrate, at least two key groups disposed on the flexible substrate, a circuit board disposed on the flexible substrate, a connector electrically connected to the circuit board and a fixative element having a first connecting portion and a second connecting portion disposed on the substrate. As the flexible substrate is properly tensed to let the first connecting portion join the second connecting portion, the overlapped key groups and the circuit board are all wrapped by the flexible substrate. The folded keyboard is pocket size and easily transported and deployed.

Abstract: An anchoring structure for a folding keyboard includes a first base, a second base and a linkage means. The first base has an upper surface which has a first key zone located thereon and an inner edge which has a first pivot joint located thereon. The second base has an upper surface which has a second key zone located thereon and an inner edge which has a second pivot joint located thereon. The first and second pivot joint engage respectively and pivotally with two edges of a linkage means so that the first and second bases and the linkage means may be folded and extended. The first and second bases have respectively a lower surface which has a slide channel located thereon and corresponding to each other to form a sliding path when the keyboard is extended. A slide block is located in one of the slide channel and movable reciprocally on the slide path. When the slide block is moved to the middle position between the two bases, it produces a constraint effect on the keyboard and allows the keyboard to be extended on a flat surface.

Abstract translation: 用于折叠键盘的锚定结构包括第一基座，第二基座和连杆装置。 第一基座具有上表面，其具有位于其上的第一键区域和位于其上的具有第一枢转接头的内边缘。 第二基座具有上表面，其具有位于其上的第二键区域和位于其上的具有第二枢转接头的内边缘。 第一和第二枢转接头分别啮合并且可枢转地连接在连接装置的两个边缘上，使得第一和第二基座和连接装置可以被折叠和延伸。 第一基座和第二基座分别具有下表面，该下表面具有位于其上的滑动通道并且彼此对应以在键盘延伸时形成滑动路径。 滑动块位于滑动通道中的一个中并且在滑动路径上往复运动。 当滑块移动到两个基座之间的中间位置时，它会对键盘产生约束效应，并允许键盘在平坦的表面上延伸。
