A window covering drive system mountable in a sash frame, such as an interior sash, for use in operating a window covering mounted to the sash. The drive system including a drive component couplable to the covering, the drive component including a belt and a belt tensioning mechanism providing pre-tension in the belt and sustaining tension during operation of the drive system. The drive system also including an operator assembly slidably mounted to the sash and coupled to the drive component, such that linear motion of the operator assembly results in movement of the belt and rotary action of the drive component to operate the covering. The drive system may include a frame connecting corner lock configured with features that couple to the drive component. Additionally, a covering operating mechanism may be included having a lift spool with a varying diameter about which a lift cord is wound and unwound.

A window assembly having a window frame and at least one primary sash mounted in the window frame. The primary sash has a plurality of sash members forming a primary sash perimeter and a first glazing panel mounted in the primary sash perimeter. At least one secondary sash is pivotally attached directly to the primary sash perimeter along an interior surface thereof so that the secondary sash is rotatably movable between a closed position and an open position relative to the primary sash. The secondary sash has a plurality of secondary sash members forming a secondary sash structure and a second glazing panel mounted in the secondary sash perimeter. An air chamber is located between the primary sash and the secondary sash that is substantially closed to the interior of the building structure. At least one accessory channel is locating along at least one side of the secondary sash members.

A window covering leveling method for a moveable rail actuated by at least one lift cord. The leveling method including the steps of providing a lift cord adjustment mechanism mounted within the moveable rail; attaching the lift cord to the adjustment mechanism; adjusting the lift cord length through operation of the lift cord adjustment mechanism so as to facilitate leveling of the moveable rail; and fixing the lift cord at the adjusted length.
摘要:
A window covering leveling mechanism for a moveable rail actuated by at least one lift cord. The leveling mechanism including a lift cord adjuster configured for attachment to one end of the lift cord; and a locking mechanism mountable within the moveable rail and configured to receive the lift cord adjuster. Insertion of the cord adjuster attached to the lift cord into the locking mechanism facilitates leveling of the moveable rail by adjustment of the lift cord and locking of the lift cord at a desired length. The cord adjuster may be a zip tie or similar item.

The present invention provides a sealed level latch for securing a door panel of a cabinet or the like in a closed position relative to the frame. The sealed lever latch is installed within an aperture formed in the door, and releasably retains the door against the frame when the door and the frame are latched together. The sealed lever latch includes a housing for mounting in the door, a handle assembly which is pivotally attached to the housing, and rotatable between an opened and closed position, and a fastening means. The fastening means retains the door, when the door is closed against the frame, by engaging the frame as the handle assembly is rotated to the closed position. The housing, handle assembly and fastening means form a integral solid structure for preventing the passage of matter through the latch itself. The sealed lever latch further includes a biasing means which is adapted to retain the handle assembly in the closed position, and urge the handle assembly from the closed position to the opened position upon disengagement. A trigger means is also included for latching the handle assembly in the closed position, and unlatching the handle assembly from the closed position for movement to the opened position. The trigger means which is integrally disposed within the central vicinity of the handle assembly provides increased mechanical advantage during the closing thereof.

A pawl assembly comprising a threaded shaft of noncircular cross section, a pawl of generally elongate shape having a circular through hole, and a clip that is nonrotatably mounted on the shaft and which contacts the pawl to prevent rotation thereof. The clip has a noncircular through hole that corresponds to the noncircular cross section of the shaft and a bent portion that contacts a side surface of the pawl to prevent rotation. By using such a clip, the pawl can be oriented in multiple angular directions while also providing for precise axial placement on the shaft. The pawl assemblies may be used in latches for cabinets and the like.

An actuation system for use with an adjustable covering for a fenestration product. The actuation system coupled to an operator for controlling adjustment of extension and contraction of the covering. The actuation system including at least one lift mechanism configured to decouple the actuation system from the operator during a potentially damaging event, such as slack in a lift cord during extension of the covering. The lift mechanism later recoupling the actuation system and operator while maintaining rotational registration between multiple lift mechanisms of the actuation system.

A door with a moveable window sash and a method of operating the same. The door includes vertical jambs with vertical channels. A window sash is movable in the vertical channels. A retractable screen assembly is attached to the door. The retractable screen assembly includes a roller, a flexible screen attached at a first end to the roller and at a second end to the movable window sash, and a biasing mechanism adapted to apply a continuous torque to the roller. The torque generates a positioning force on the window sash equal to at least 50% of the force of gravity acting on a window sash, such that the window sash can be positioned at an infinite number of locations along the vertical channels.

A draw latch includes a handle assembly comprising a base, a lever and a catch. The handle assembly is mounted on a first panel and is adapted for fastening a keeper mounted on a second panel. When the latch is fastened, the catch engages the keeper which operates to draw the panels together. When the latch is unfastened, rotation of the lever provides corresponding rotation or "kick-out" of the catch from engagement with the keeper.
