Muntin grid assembly and mounting system

摘要

A muntin bar assembly for a window or door including a peripheral frame; a continuous surface contained within the frame; at least one continuous muntin bar and at least two discontinuous muntin bars on at least one side of the surface. The continuous muntin bar and discontinuous muntin bars both contain a continuous recessed portion on their underside and are connected together using an intersection clip having a spring-type arrangement which forms an intersection of the bars. The intersection clip has a raised central section that fits within the recessed portion of the continuous muntin bar; and further has two extensions positioned at opposite sides from the central portion which permit engagement of the discontinuous muntin bars to form the muntin assembly. An end clip is also included for attachment and alignment of the inner and outer assembly muntin bar ends and has a U-shape that fits over the edges of the surface for aligning and attaching the inner and outer assembly muntin bars.
