US Patent 10532428 Interlocking flexible segments formed from a rigid material

A method for creating a flexible portion or bending portion within a rigid structure. The method can also be used for creating a flexible structure from a rigid material. The method includes providing a substantially rigid material, such as, but not limited to, metals, alloys, hard plastics, and the like, and selectively removing portions of the rigid material defining a geometric pattern in the rigid material. A bending radius of the flexible portion is defined by the geometric pattern. The rigid structure may be used to create an enclosure, a cover for an electronic device, one or more hinges, or the like.
