<p>A structural joint (10) for connecting picture frames members together includes a base plate (12) slidably residing in a channel (42) of a first picture frame member and includes a ramped surface. A wedge plate (14) slidably resides between the base plate (12) and a top bearing surface of the frame (24) and includes its own ramped surface where the ramped surface of the wedge plate (14) is arranged in an opposite direction to the ramped surface of the base plate (12). The wedge plate (14) is moved toward the base plate (12) to cause the ramp of the base plate (12) to bear on the ramp of the wedge plate (14) to urge the base plate (12) apart from the wedge plate (14) creating a friction fit within the channel (42) of the picture frame member (24) thus securing the base plate (12) relative to the frame (24). A second wedge plate is also provided for engagement with a second ramp on the base plate to further secure a second picture frame member (26) to the first picture frame member, such as at a ninety degree angle relative thereto. The wedge plates (14) are connected to the base plate (12) to ensure alignment of the ramped surfaces and to facilitate installation.</p> |
