Patent ID: 8659893

Claim:
A protection casing of an electronic device with a function of supporting, comprising: a lower casing ( 10 ) having an approximately rectangular shape; a periphery of the lower casing being formed with a frame for enclosing a tablet computer; a supporting sheet ( 20 ) including at least one kind of foldable traces; the supporting sheet being foldable along the foldable traces so as to present a three dimensional structure; a combining band ( 201 ) formed at an upper side of the supporting sheet adhering the supporting sheet to the lower casing; and wherein after assembly the supporting sheet to the lower casing, the supporting sheet can be folded along the foldable traces to form as a seat for standing the lower casing; and an electronic device can be placed on the lower casing for being supporting thereon; and wherein the foldable traces divide the supporting sheet into three triangular sections and two oblong sections, which are formed by locating a point (P) near a lower side of the supporting sheet ( 20 ); a foldable line (H) approximately parallel to the lower side of the supporting sheet ( 20 ) passing through the point (P); then two foldable lines (Q and R) extending from the point (P) to two upper corners of an upper side of the supporting sheet ( 20 ) so that to divide the supporting sheet ( 20 ) into three triangular sections (A, B and C); another foldable lines (S) extend downwards from the point (P) to the lower side of the supporting sheet ( 20 ) so as to divide the lower portion of the supporting sheet ( 20 ) into two oblong sections (D and E); and these sections being connected flexibly so that the adjacent sections are foldable with respective to one another.
