Abstract: A sliding window is disclosed for use in homes, apartments or businesses. A frame is provided having a sill, header, jambs and a mullion all of which can be produced from extruded aluminum sections assembled into a rigid frame. Two framed window panels are contained in the rigid frame, one panel has a fixed location the other panel slides relative to the rigid frame. Each panel is carried in a separate groove having a vinyl liner. The grooves are separated by a spacer. The sliding panel rides on rollers in its respective groove and is opened, closed and locked by a handle. The fixed panel also rides on rollers and is fixed in its location by the removable mullion which securely locks the frame header and sill together. The mullion has tabs extends through one of two sets of slots in the header and sill where it is secured by a screw. The fixed panel may be located on the left or right hand side of the frame as desired. One set of slots is used by the mullion to lock the fixed panel in the desired location.

Abstract: A sliding window to be installed in a rough frame opening in a wall. The window comprising a frame including a sill, header, two jamb members and a removable mullion. Contained in the frame are a fixed panel and a sliding panel. A locking handle is provided for the sliding panel. More importantly the removable mullion allows the fixed panel to be secured in the left or right hand side of the frame as desired. Seals and frame features prevent air and sound leakage particularly under stress from a heavy wind. Also disclosed is an anti-lift stop device to prevent removal of the movable panel.

Abstract: A molded plastic assembly for sliding screen closures employing a body made up of two separate parts which embrace the frame of a sliding screen closure and including an integral deflectable latching finger having an end portion which acts as a stop and which may be locked or unlocked by mere finger pressure against the deformable locking finger in order to engage or disengage from the door frame. The handle assembly employs the resilient characteristics of the material from which it is produced to provide the deflectable latching finger.

Abstract: A novel handle for use in sliding windows and the like formed as a single member and providing the functions of a handle, a catch and a resilient spring release portion which is formed integrally with the handle. The handle includes a surface which may be bonded to the surface of a window light or door by an adhesive while still providing the necessary functions of a gripping handle, a catch and a spring catch releasing mechanism.

Abstract: A simple, adjustable roller assembly for supporting sliding track doors and windows and comprising a U shaped bracket which journals a roller and includes a corner opposite from the journaled roller which engages the intersection between the stile and rail of a door frame. An adjusting screw passes through the stile or rail and engages the U shaped bracket whereby tightening of the screw pivots the bracket and roller into increasing downward movement by pivoting the bracket with respect to the inside corner defined by the junction of the stile and rail. In one alternate embodiment, a single screw adjusts a pair of side by side rollers journaled on a common shaft. In another embodiment the U shaped member includes a tap member extendable outward and securable at a spaced point on the door rail or sill. Tightening of this screw serves to bend the tab member and adjust the roller position. The bendable tab actually provides a degree of spring support for the door.

Abstract: A frameless sliding window assembly employing only two shapes for the window casement and with no mullion required. A sliding glass pane is supported to approximately one half its thickness by an elongated plastic key which allows rain and dust to pass to the exterior through weep holes in the casement. A single casement extrusion holds a fixed lite, seals the movable lite and constitutes a screen frame member.A novel handle is in the form of an extruded shape with a mounting surface, an upstanding handle portion, a catch and an intermediate resilient spring portion.
