Abstract:
A fastener assembly for inserting an elongated fastener member within an opening defined by an overhead horizontal or vertical structural portion or arrangement having at least one concealed side, commonly called a blind hole, and comprising:A. a primary component consisting of a specially or specifically shaped nut,(1) said nut having the width and thickness dimensions slightly smaller than the dimensions of said blind hole through which said nut is to be passed, but having length sufficiently greater than said blind hole's dimension;(2) said nut further having a threaded bore piercing the approximate center of said nut's largest contact areas and perpendicular to the longitudinal and transverse axes thereof capable of threadedly engaging a commercially produced bolt of appropriate size and kind;(3) with a generally rectangular slot through the material from which said nut is fabricated and of predetermined size located proximate to the longitudinal terminal edge distal from said threaded bore; and(4) having the bottom surface of said nut, which will be proximate to the inaccessible surface of the securing member in said fastener's operational position, configured with a stepped, or bi-level, portion, the thicker of which portion will contact said inaccessible surface of the securing member; andB. a secondary component consisting of a substantially rectangular, flat plate of approximately the same width as said nut, but only nominally greater than half the length of said nut, and of approximately the same thickness dimension as the difference in height between said configurationally stepped bottom surfaces of said nut, said plate being:(1) attached hingedly to said nut through said slot, as described in subparagraph A(3), above, in such a way that said plate can be pivoted slightly more than 180.degree. transversely about its pivot point, being constrained from further pivotal movement by the body of said nut, so thata. in the procedure for inserting said nut into said opening, said plate can be fully extended outward laterally from said nut at its pivotal point of attachment to said nut, andb. said plate, following said insertion procedure, can be pivoted then in the opposite direction to abut the contiguous surface of said nut, wherein said plate and said nut are juxtaposed, thus presenting an approximate single level plane for contact that obviates an uneven distribution of pressure from said bottom contact surface of said nut with said inaccessible surface of the securing member when the fastening device is tightened;(2) also pierced by a threaded bore of the same predetermined size and kind as that of said nut, as explicated in subparagraph A(2), above, that penetrates said plate proximate to its edge distal from the point of pivotal attachment to said nut and that is relatively perpendicular to the longitudinal and transverse axes of said plate; and(3) said plate being further defined as including the diameter of its threaded bore therein plus the width of a thin rim of material from which formed sufficient to contain the helical threads of the bore piercing this distal terminal edge.
