The self-locking hinge (24) includes a first plate (28) hingedly connected to a second plate (30). Fasteners (24) are provided on the plates to secure them to a member, such as an easel strut hinge (24) of picture frame back (20). A locking structure is connected to the first plate (28) and the second plate (30) for maintaining the second plate (30) in the substantially open position relative to the first plate (28). The locking hinge (24) includes a protrusion (36) on the first plate (28) that removably engages with a free edge (34) of the second plate (30). The hinge (24) also includes a structure for maintaining the second plate (30) in rotating arrangement with the first plate (28) when the plates (28, 30) are hingedly secured to one another in a rolled pinless fashion. Locking lugs (40) are used to maintain the second plate (30) rolled about the first plate (28). |
