FOLDING DEVICE

摘要

A folding device provides a top case having magnetic elements at a top magnetic section and a bottom case having a groove and magnetic elements around the groove at a bottom magnetic section. As the top magnetic section of the top case is disposed at the bottom magnetic section of the bottom case, the top case is configurable at one of a folded position and at least two opened positions with respect to the bottom case. When the top case is at the first opened position, a first stopper and a first magnetic element at the groove of the bottom magnetic section maintain the top case at the first opened position; when the top case is at the second opened position, a second stopper and a second magnetic element at the groove of the bottom magnetic section maintain the top case at the second opened position.

主权项

1. A folding device, comprising:
a bottom case having a bottom magnetic section, the bottom magnetic section comprising:
a groove, comprising a first abutting portion, a bottom surface, and a supporting surface, the bottom surface between the first abutting portion and the supporting surface;a lower magnetic element disposed near the first abutting portion;a first magnetic element disposed near the bottom surface;a first stopper disposed between the bottom surface and the supporting surface; anda second stopper disposed at an end of the supporting surface; and a top case having a top magnetic section, the top magnetic section comprising a upper magnetic element disposed at a bottom end of the top case, the top case selectively configurable at a folded position, a first opened position, or a second opened position with respect to the bottom case, wherein:
when the top case is at the folded position, the upper magnetic element and the lower magnetic element are in attraction with each other;when the top case is at the first opened position, a second abutting portion of the top case abuts against an end portion of the first abutting portion, the upper magnetic element and the first magnetic element are in attraction with each other, and the bottom end is positioned by the first stopper; andwhen the top case is at the second opened position, the second abutting portion abuts against the end portion of the first abutting portion, and the bottom end is positioned by the second stopper;wherein the top case moves from the first opened position to the second opened position via the second abutting portion moving relative to the bottom case.
