Abstract
A free-wheeling latching mechanism for securing a removable closure frame to a second closure frame includes a latching plate rotatable on a shaft fixed to, and spaced from, the second frame by a flange integrally formed on the shaft. A cap nut is used to retain the latching plate on the shaft during rotation, while providing spacing from the flange, and a sill attached to the second frame is used to support the removable frame during rotation of the latching plate.
Claims7
Apparatus for securing a removable, first closure frame in a second closure frame, wherein the edge of the first frame extends perpendicularly an overhang distance beyond the edge of the second frame, the apparatus comprising:
- (a) a shaft non-rotatably attached to said second frame and extending perpendicular to the edge of said second frame;
- said second frame being vertically disposed;
- (b) an elongated latching plate having an eccentrically positioned aperture sized for free-wheeling rotation of said plate on said shaft;
- (c) means for spacing said latching plate from said first frame to allow rotation of said latching plate from said first frame to allow rotation of said latching plate past the edge of the first frame to a position wherein the first frame is captured between said plate and the second frame;
- (d) means for retaining said latching plate on said shaft during said free-wheeling rotation of said plate;
- and
- (e) means for aligning and supporting the first frame during rotation of said latching plate to said capture position.
