NON-ROTATING, TOGGLE BOLT ASSEMBLY Inventor: Louis N. Giannuzzi, a citizen of the United States of America and resident of Cos Cob, Conn. ABSTRACT OF DISCLOSURE A non-rotating toggle bolt assembly in which a trunnion nut received on the end of a screw whose length exceeds the thickness of the hollow wall for which the assembly is intended, pivotally supports a pair of spring-biased toggle wings. The wings are normally outstretched; but when the assembly is pushed through a hole drilled in the wall, the wings then fold in against the screw to permit passage therethrough. On emerging from the hole, the pivoting wings resume their outstretched state at a position well displaced from the inner surface of the wall. Included in the assembly are locking means which act to prevent rotation of the outstretched wings when, in the course of installation, the operator turns the screw to advance the toggle axially toward the inner surface of the wall to tighten the assembly, and which also acts to prevent loosening of the assembly such as might be caused by vibration, after such installation.
