Patent ID: 7707796

Claim:
A method for installing a curtain wall portion to a building frame, comprising the steps of: i) providing structural members with first connection members; ii) providing glazing panels and positioning second connection members on a sash of the glazing panels, the second connection members each having a biased latch bolt, a spring biasing the latch bolt in a first direction, the latch bolt having a ramp surface; iii) installing the structural members to a building framing so as to define frames adapted to support glazing panels; iv) automatically latching the glazing panels to frames by inserting the glazing panels within the frames along an axis generally normal to the frames, whereby the latch bolts of the second connection members move to a retracted position opposite the first direction upon contacting the ramp surface with the first connection member and back to a projecting position after the ramp surface passes the first connection members to lock the glazing panels to the frames; and v) forcing the latch bolts of the second connection members into a blocked position.
