Hardware for opening a frameless window into laterally displaced parallel positions

摘要

A window pane is mounted in a closed position outside a window frame, commonly referred to as a frameless window, and is movable into open positions parallel to the closed position. The window pane can be slid into a fully open position. Sliding mechanisms are attached to the window pane. Swing arms connect the sliding mechanisms to the window frame. Control arms also connect the sliding mechanisms to the window frame. They determine the distance of and control the translation of the window pan from the closed position to the initial open position. A handle is attached to at least one of the sliding mechanisms or window pane. Latching mechanisms secure the handle in the open positions. The invention is designed so that a plurality of screens allows air flow through the window frame, preventing passage of insects or debris through the window frame.

主权项

1. 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.
