Kind Code:
A3
Abstract:
The improved pinless hinge assembly (24) includes a first hinge plate (28) having a curled edge (28a) defining a center roll having a longitudinal axis (P) with an aperture (42) in the first hinge plate (28). A second hinge plate (30) having a free edge (30a) curled about the center roll. A locking lug (40) extends from the free edge (30a) of the second hinge (30) and is routed first through the first aperture (42) in the first hinge plate (28) and then through the second aperture (44) in the second hinge plate (30). The locking lug (40) is engaged in a seat (46) in the second hinge plate (30) to maintain the free edge (30a) of the second hinge plate (30) curled about the center roll when the first hinge plate (28) rotates relative to the second hinge plate (30) about the longitudinal axis (P). A pair of locking lugs (40) may be also be used. Fasteners (26a, 26b), such as rosettes, may be respectively employed to connect the first hinge plate (28) to a picture frame strut (18) and to connect the second hinge plate (30) to a picture frame back (20).
