Sliding window assembly with flush-closing moving panel

A window assembly, comprising:

• a fixed panel defining an opening;
• a rail that attaches to the fixed panel;
• a guide provided on the rail and defining grooves having substantially equal depths within the guide;
• a shoe at least partially overlapping the guide and defining slots including a first slot and a second slot, the first slot and the second slot defining different shapes;
• and
• a moving panel supported by the shoe and interacting with the guide by pins that extend through the slots and into the grooves such that the slots, together with the grooves, cause the moving panel to slide within the slots and with respect to the fixed panel between a closed state, in which the moving panel blocks the opening and is substantially flush with the fixed panel, and an open state in which the moving panel unblocks the opening,
• wherein the slots include a substantially L-shaped slot defining a long arm substantially parallel to the fixed panel and a short arm substantially perpendicular to the long arm and facing away from the fixed panel, wherein the long arm prevents sliding of the moving panel in a direction substantially perpendicular to the fixed panel such that the moving panel is locked against the fixed panel in the closed state.

• a rail that attaches to the fixed panel;
• a guide provided on the rail and defining grooves including a first groove and a second groove;
• a shoe at least partially overlapping the guide and defining slots facing away from the fixed panel and including a first C-shaped slot overlapping the first groove and a second L-shaped slot overlapping the second groove;
• and
• a moving panel supported by the shoe and interacting with the guide by pins that extend through the slots and into the grooves such that the slots, together with the grooves, cause the moving panel to slide within the slots and with respect to the fixed panel between a closed state, in which the moving panel blocks the opening and is substantially flush with the fixed panel, and an open state in which the moving panel unblocks the opening, the pins including a first pin that slides within the first groove and the first slot and a second pin that slides within the second groove and the second slot,
• wherein the second L-shaped slot defines a long arm substantially parallel to the fixed panel and a short arm substantially perpendicular to the long arm and facing away from the fixed panel, wherein the long arm prevents sliding of the moving panel in a direction substantially perpendicular to the fixed panel such that the moving panel is locked against the fixed panel in the closed state.
