A latching mechanism for a pair of relatively slidable overlapping window panels includes a pair of opposed fixed support blocks with bearing surfaces engageable with the outside surfaces of the window panels. A first wedging block is floatingly mounted between the window panels and has a bearing surface engageable with the inside surface of one window panel and a slanted wedging surface spaced from the inside surface of the other window panel. A latching lever, movable between operative and inoperative positions, is secured to a second wedging block which has a wedging surface engageable with the wedging surface of the first wedging block and a bearing surface engageable with the inside surface of the other window panel. In the operative position of the lever, the engagement of the wedging surfaces of the wedging blocks engages the bearing surfaces of the wedging blocks with the inside surfaces of respective window panels to wedge the panels against the bearing surfaces of the support blocks. When the lever is rotated to inoperative position, the second wedging block is moved out of engagement with the first wedging block, to allow the window panels to slide freely relative to each other.

A latching mechanism for latching a pair of relatively slidable overlapping window panels, either one of which is slidable, to each other at an infinite number of relative positions, comprising, a mounting member, a pair of opposed support blocks fixed to the mounting member, each block having a bearing surface engageable with the outside surface of a respective window panel at the overlap thereof, a first wedging block located between the opposed support blocks, said first wedging block having a bearing surface engageable with the inside surface of one window panel opposite one support block and a wedging surface spaced from the inside surface of the other window panel, means floatingly mounting the first wedging block to the mounting member to allow its bearing surface to be moved freely into and out of engagement with the inside surface of the one window panel, a second wedging block located in the space between said first wedging block and said other window panel including a bearing surface engageable with the inside surface of the other window panel opposite the other support block and a wedging surface engageable with the wedging surface of the first wedging block, and means for moving the second wedging block at any relative position of said window panels between an operative position wedged between the first wedging block and the inside surface of the other window panel to bias the bearing surfaces of the wedging blocks into the inside surfaces of the window panels to in turn force the outside surfaces of the window panels into the bearing surfaces of the support blocks and latch the window panels in an infinite number of overlap positions and an inoperative position free of wedging engagement with the first wedging block, said means floatingly mounting said first wedging block allowing the bearing surface of said wedging block to be moved away from the inside surface of said one window panel to free the window panels for relative sliding movement.
