Abstract: A retractable screen panel installation for a garage door in which the screen panel may be held latched in a position overlying a lowermost section of a garage door, and selectively released to slide down to cover an opening created when the door is partially raised. A one handed operation of two laterally spaced latching mechanisms releases the screen panel by squeezing together two angled end pivoted release levers each connected to a respective cable release element.

Abstract: A raised panel door section (22, 54, 64) for an overhead garage door (20, 50, 60) includes a sheet metal layer (32, 56, 66) formed from sheet metal stock (74) that is embossed to produce a raised panel design by an automated method that selects one of a first die set (84) and a second die set (90) in response to a predetermined embossment style, installs the selected one of the first and second die sets (84, 90) into an embossing press (36) and embosses the sheet metal stock (74) with the predetermined embossment style. The predetermined embossment style includes one of a vertical raised panel design (30), a horizontal raised panel design (52), and a horizontal long raised panel design (62). An overhead garage door (20) includes three of the raised panel door sections (22) having the sheet metal layer (32) embossed with the vertical raised panel design (30).

Abstract: A level adjuster for window shades facilitates the level adjustment of the lower rail, in a single operation without requiring any disassembly of the installation. The adjuster comprises a clip or clamp installed in one end of a conventional hollow rail. The adjuster clip has a pair of arms and a tongue or shoe extending into the rail interior, bearing against a crossmember extending between the two arms. The draw cord or lifting line extends as a continuous length through one rail, down each side of the shade assembly, and through the opposite rail where it wraps around the adjuster crossmember and is gripped by the gripping shoe. Lower rail adjustment is accomplished by inserting a tool (nail, etc.) through a hole in the end of the adjuster to flex the resilient shoe away from the crossmember, thereby freeing the lifting line gripped between the shoe and crossmember.

Abstract: A covering for window or doors includes a plurality of vanes mounted horizontally or vertically, the vanes being light in weight and longitudinally rigid. The vanes may be foam filled or may include a vane shell made from a polymer matrix, and in either case may optionally include a decorative fabric covering. In the hollow vane embodiment, the vane shell preferably includes a polymer matrix at least partially enveloping fibers, and in the most preferred embodiment is prepared from a fibrous batt including two different thermoplastic resin fibers, one having a lower melting point than the other. The vane shell is formed by thermally treating the batt to at least partially melt the lower melt fibers to at least partially envelope the higher melt fibers.

Abstract: A shutter has a shutter panel and a pair of guide rails that hold both end portions of the shutter panel slidably. The guide rails have curved portions. Each of the guide rails includes straight members having parallel tie plates and an interval plate connecting central portions of the tie plates resulting in an H-shaped section. Each of the guide rails includes corner members having curved plates succeeding to the tie plates. Both end portions of the shutter panel are inserted slidably between inner half portions of the tie plates partitioned by the interval plates, and outer half portions of the tie plates are mounted to a fixing portion to thereby enable smooth sliding movement of the shutter panel within the guide rails.

Abstract: A joist hanger used to attach a joist to a support member or header designed to minimize the noise caused by the rubbing of the members of the connection, during loading. The joist hanger includes a seat and a pair of side walls extending upwardly in spaced relationship therefrom to receive the end portion of an joist. The bottom of the joist rests on the seat, and the side faces of the joist extend upwardly therefrom in spaced relationship from the side walls of the hanger. Inwardly projecting guides formed in the side walls of the hanger, hold the joist at selected points, maintaining the spaced relationship between the sides walls of the hanger and the side faces of the joist. The inwardly projecting guides can be formed with embossed portions connected to the side walls of the joist. The joist hanger is also formed with back flanges and top flanges that are relatively narrow compared to the back flanges.

Abstract: A form assembly is constructed from a plurality of wall panels joined in side by side relationship by interposed adapters. The adapters have end plates in which reliefs are formed to accommodate alignment walers that extend along the top and bottom of the form assembly to maintain planar alignment of the form assembly. The reliefs allow the walers to be recessed so that they do not extend beyond the horizontal plane of the top and bottom of the wall panels. The form assembly is used to create a form in which concrete is poured to create a concrete wall, such as a foundation wall for a house. Because the form assembly can be installed and removed as a single piece rather than multiple individual wall panels, the time required to erect and remove the form is reduced.

Abstract: A Roman blind is provided which includes a head rail and a web of fabric material attached at a first end to the headrail. A pair of lifting cords extend from the headtail to a second end of the fabric web, to which they are attached. Two columns of guide elements are provided wherein each column guides a respective lifting cord. The guide elements of each column are arranged also to provide horizontal rows, about which the blind folds when raised. A pair of connecting tapes are disposed between the head rail and the second end of the fabric web. The tapes are secured to the fabric web by the guide elements, whereby unfolding of the fabric web is constrained by the tapes to a pre-defined maximum spacing between vertically adjacent pairs of guide elements, the maximum spacing between the vertically adjacent pairs of guide elements being less than the corresponding length of fabric web disposed between them.
