Hardware for opening a frameless window into laterally displaced parallel positions

Apparatus for a window comprising:

• a window frame assembly,
• a window pane, and
• hardware engaged with said window frame assembly and said window pane for translating said window pane between a first closed position and an open second position parallel to the first closed position outside said window frame, and for laterally displacing said window pane between said open second position and an open third position,
• said hardware comprising:
• one or more sliding mechanisms coupled to said window pane to laterally slide said window pane between said open second position and said open third position,
• means for translating said window pane to and from said first closed position and said open second position, comprising swing arms for securing said one or more sliding mechanism to said window frame and supporting said window pane, and control arms for extending and retracting said sliding mechanisms, said control arms being configured to retain said one or more sliding mechanisms in said open second position and establishing a determined distance of parallel translation from said first or closed position to said open second position;
• a handle for sliding said window pane between said open second position and said open third position, and
• a screen to prevent passage of insects and other debris through said window frame, said screen comprising a slot through which said handle passes, to allow said handle to slide between said open second position and said open third position.
