A vent for mobile living quarters has a base and a cover coupled to the base. The cover is connected to the base and pivots about a hinge by a mechanism that is coupled to a moving bar. The moving bar is attached to the cover by fasteners on one end and an alignment tab on the opposite end. The cover is user-replaceable from the top side without having to move or disconnect the mechanism. To replace the cover, fasteners are removed and the cover is pivoted away from the moving bar, where the alignment tab disengages from the cover. The cover is then slidable along the hinge to completely remove the cover from the base. A new replacement cover is slid along the hinge and the alignment tab is engaged with the replacement cover. The cover is pivoted down to a closed position and the fasteners are reinstalled.

Hardware for a lift glide door assembly and lift glide window assembly provides ease of opening with an operational opening assist that urges the door or window to an open position on operation of an opening handle by use of a cable drive system. A lock mechanism actuates a lock pin, blocks opening gear mechanisms from operating and extends a security bolt for locking. A guide blade is provided for assisting the door during opening or closing operations.

A lid controlling apparatus includes a casing having a target region, a lid, and a rod driving mechanism connected between the casing and the lid. The rod driving mechanism includes a first rod pivoted to the casing, a non-rotatable gear fixed to the casing, a driven gear pivoted to a side of the first rod and connected to the lid, and a planetary gear device pivoted to the side of the first rod and engaged with the non-rotatable gear and the driven gear for rotating between lifting and closed positions. When the planetary gear device rotates to the lifting position, the first rod pivots with rotation of the planetary gear device to have a first included angle relative to the casing, and the planetary gear device rotates the driven gear to make the lid have a second included angle relative to the first rod for exposing the target region.

An integrated casement window operator and lock, including a gear mechanism and an arm assembly, the arm defining a rack portion and an adjacent arcuate gear portion, the arm mounted to the housing with a pinion gear engaged with the rack portion and the arcuate gear portion, the pinion gear defining a star-shaped aperture therethrough and a handle with a square-shaped shaft portion received in the star-shaped aperture of the gear. The handle is selectively rotatable to shift the arm between a window fully closed position and a window fully open position, wherein an anti-backdrive mechanism is provided to inhibit backdriving of the arm in both the window fully closed window fully open positions.

A window operator for repositioning a window sash within a window frame. The window operator includes a crank handle for rotating a shaft with a pinion gear. The pinion gear operably engages with a rack containing cutouts, the rack having oppositely disposed first and second ends. The rack is translatable within a track disposed within the window frame. The window operator also includes an operator arm connectable between a first end of the rack and the sash wherein rotation of the shaft by the handle imparts movement to the rack and the operator arm, the rack and operator arm movement capable of transitioning the sash between a window open and a window closed position.
