Split blocks with multiaxis living hinge systems and methods for making the same

A method of manufacturing a split block assembly for a wall structure with a fixture, the method comprising:

• forming a backplate configured to mount to the wall structure, the backplate including a first plate segment rotatable with respect to a second plate segment between an open position, whereat the first plate segment is spaced from the second plate segment, and a closed position, whereat the first and second plate segments abut and thereby cooperatively define a fixture hole configured to receive therethrough the fixture;
• and
• forming a living hinge system integral with and rotatably joining the first and second plate segments, the living hinge system including a first living hinge adjoining the first plate segment and bending on a first axis, a second living hinge adjoining the second plate segment and bending on a second axis oblique to the first axis, and a flap extending between and joining the first and second living hinges.

A mounting block, comprising:

• a split block backplate including at least a mounting flange, a first plate segment, and a second plate segment separated from the first plate segment by a split block line;
• and
• a living hinge system connecting the first and second plate segments to rotate back-and-forth between open and closed positions, the living hinge system consisting essentially of multiple living hinges joined by at least one inter-hinge flap, wherein the at least one inter-hinge flap is generally coplanar to the mounting flange when in the closed position and non-planar to the mounting flange when in the open position.
