Non-rotating toggle bolt assembly

A non-rotating toggle bolt assembly for supporting a fixture or other object against the outer surface of a hollow wall, said assembly comprising:

• A. a bolt having means at one end to effect turning thereof, and a threaded shank whose length exceeds the thickness of the wall for which it is intended;
• B. a collapsible toggle threadably received on the end of the shank, said toggle when in the collapsed state assuming reduced dimensions permitting its passage through a hole in the wall, the toggle when emerging from the hole assuming enlarged dimensions;
• and
• C. locking means to prevent rotation of the toggle, whereby when said bolt is turned, the toggle will then advance along the shank toward the inner surface of the wall to engage said inner surface, said locking means being constituted by an elongated member coupled at one end to the toggle and having a restraining zone therein whose form is such as to cause it to engage the wall of the hole, the length of the member being such that in the course of installation when the toggle is collapsed to pass through the hole, the member but not the restraining zone also passes therethrough, the restraining zone being substantially closer to the bolt turning means than the toggle is to the turning means, and the restraining zone do not emerge from the hole but engages the wall of the hole when the toggle after emerging from the hole assumes its enlarged dimensions, whereby the restraining zone prevents rotation of the toggle, said elongated member being a strap extension provided with a relatively broad end portion that functions as the restraining zone.
