A connector device is provided for a curtain wall system of the type having structural members secured to the building framing to define frames to support glazing panels. The glazing panels each have a sash by which they are secured to the frames of structural members to form an outer wall portion of a building. The curtain wall system has connector devices securing one of the glazing panels to the frames of structural members. The connector device comprises a keeper secured to a frame, and a latch mechanism secured opposite the keeper on the sash. The latch mechanism has a latch bolt automatically displaceable to a locking position upon contact with the keeper. The keeper and the latch mechanism cooperate in the locking position to lock the glazing panel to the frame in a secured position. A method for installing the connector device is also provided.

The invention claimed is: 1. A curtain wall system comprising: structural members secured to the building framing to define frames of rectangular shape; glazing panels each having a sash by which the glazing panels are secured to the frames of structural members to form an outer wall of a building, with each sash being attached to an inside of its corresponding glazing panel; and connector devices securing the glazing panels to the frames of structural members, the connector device having a keeper secured to the frame, a latch mechanism secured on the sash distally to the corresponding glazing panel and opposite the keeper, the latch mechanism having a latch bolt and a spring biasing the latch bolt to a projecting position, the latch bolt having a ramp surface and an abutment surface, the ramp surface of the latch bolt in the projecting position being aligned with respect to the keeper along a line normal to the plane of the frame for the ramp surface to contact the keeper when installing the sash in the frame by moving the glazing panel into the frame of rectangular shape along an axis generally normal to the frame, the latch bolt retracting from the projecting position as a result of the contact between the keeper and the ramp surface, the latch bolt returning to the projecting position when the ramp surface is beyond the keeper, the keeper and the abutment surface of the latch mechanism in said projecting position cooperating beyond the keeper to lock the glazing panel to the frame in a secured position. 2. The curtain wall system according to claim 1, further comprising release means connected to the latch mechanism, the release means being actuatable from an inside of the building to release the latch mechanism from the projecting position for the removal of the glazing panel from the secured position. 3. The curtain wall system according to claim 1, wherein the keeper is an extruded projection of the structural members, the keepers being integrally extruded parts of the structural members. 4. The curtain wall system according to claim 2, wherein the release member is the pin projecting from a rear end of the latch bolt. 5. The curtain wall system according to claim 4, wherein the pin has a pin head concealed within a cavity formed by a channel and a cover plate of the sash of the glazing panel. 6. The curtain wall system according to claim 5, wherein the pin head is sized such that the cover plate can only be secured to the sash if the latch bolt is in a locking position. 7. The curtain wall system according to claim 4, wherein the pin has longitudinal fins that are forced into engagement with a casing of the latch mechanism to block the latch bolt into a locking position.
