E05C 17/02 by mechanical means (E05C17/60 takes precedence)
Full Title
Devices for holding wings open; Devices for limiting opening of wings or for holding wings open by a movable member extending between frame and wing; Braking devices, stops or buffers, combined therewith (combined with hinges E05D11/00; combined with operating apparatus for wings E05F; other braking devices, stops, buffers E05F5/00) > by mechanical means (E05C17/60 takes precedence)
Description
E05C17/02 covers mechanical devices for holding door or window wings open or for limiting their opening, using a movable member that extends between the frame and the wing. Typical constructions include friction stays, pivoted arms, sliding rods in guide tracks, hooks and casement stays used on windows, doors and hatches. Combined braking devices, stops and buffers of this kind are also included. Non-mechanical hold-open devices, e.g. magnetic or fluidic ones, are classified elsewhere in E05C17/00, and E05C17/60 takes precedence for members moved into holding position by the wing movement.
