Abstract: A shoe for movement in a track of a closure assembly the track having at least one engaging portion, the pivot shoe comprising a carrier portion having a bottom end for movement within the track, the shoe having clamping portions for clamping said at least one engaging portion of the track of the closure assembly the at least one engaging portion being disposed between the clamping portions of the shoe when the pivot shoe is installed in the closure assembly. The shoe also has an operating mechanism, the clamping portions being in engagement with said operating mechanism said operating mechanism being moveable from a first position to cause the clamping portions to engage the at least one engaging portion of the track wherein the closure member of the closure assembly is locked or secured in position, to a second position wherein the clamping portions disengages the at least one engaging portion of the track wherein the closure member of the closure assembly is free to move in the track.

Abstract: A pivoting and sliding closure assembly is provided which rides in a guide channel of a frame upon a pivot shoe assembly which at one end securely pivots a closure member upon one pivot shoe when the closure is pivoted away from the channel, and which latches the closure member in a slidable position when the closure member is pivoted to its latched position. The pivot shoes are connected together in the assembly and unique cam structures and rollers are incorporated in the assembly.
