<p>McPherson 6 c MEETING RAIL FOR SLIDING WINDOWS A device forms a meeting rail when applied to one edge portion of a pair of overlapping marginal edge portions of closable sliding window panes, each said edge portion having an outer edge. The device comprises a pair of planar strips of semi-rigid thermoplastic material having first and second side surfaces. A connecting strip of flexible thermoplastic material is positioned between and fused at its edges to adjacent edges of the semi-rigid strips. A plurality of parallel, longitudinally extending, spaced-apart ribs are disposed on the second side surface of one of the semi-rigid strips of the device. The ribs are of a flexible thermoplastic material and are fused to the one semi-rigid strip. A pressure sensitive adhesive on the first surfaces of the semi-rigid strips enables the device to be applied and secured to the one edge portion in a U-shaped configuration with the first surfaces secured to opposite side surfaces of the one edge portion and in a position so that when a pair of said devices are applied to the pair of edge portions, the ribs of the devices extend in interdigital relationship when the panes are closed.</p> |
