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 by a multiple segment shaft in the assembly and unique rack and pinion structure is incorporated in the assembly.
