Abstract: Embodiments of a panel-less shutter assembly comprise a series of parallel louvers mounted within a closed rectangular rail frame. Spring-loaded guides may be mounted between the rail frame and the window frame to self-center the assembly within the opening of the window frame. Carriers mounted on the ends of the louvers glide up and down within channels of the side rails to allow raising and lowering of the louvers. Spring-loaded channel slides may be coupled to the carriers. The channel slides have tabs that extend through slots in the side rails to maintain the positions of the louvers relative to the side rails. The tabs have a diagonal surface that engages the top edge of the slot to disengage the tab from the slot when a user raises the louvers. A method of using a panel-less shutter assembly is also disclosed.

Abstract: A screen door made of foamed polymer with heat welded joins between rails and stiles and a flat spline groove. The rails and stiles are extruded with the flat spline groove. Prior to joining the rails and stiles, a thin notch is made to remove the smooth skin of the extruded stiles before being joined to the cut ends of the rails. The heat welded joint between the notched stile and cut end of the rail is ten times stronger than conventional polymer door joints. A flat spline is used to insert the marginal portion of the screen into the flat spline groove, which is wider in the interior than at its entrance and resists the pull from normal forces on the screen much more effectively than a round spline in a rectangular groove.

Abstract: In a roll screen device, inner rails are embedded inside fixed guide rails which guide protrusions at side edges of a screen which is wound via a take-up shaft. Each inner rail has a guide groove in which the guide protrusion is inserted, and inward flanges are provided at an opening of the guide groove. Rail members have outer side protrusions and inner side protrusion of different heights at both side edges of a rail base plate. The higher outer side protrusions are confronting. A micro gap extends between the lower inner side protrusions into the guide groove such that the micro gap is opposed to a guide gap formed between the opposed inward flanges. The guide protrusion is slid and guided in a come-off preventing state by the inner side protrusion, so that an extremely thin fastener element can be used as the guide protrusion.

Abstract: A roofing assembly includes a panel configured to define a major surface, a first end, and a second end opposite the first end; and a frame including a first transverse profile attached to the first end of the panel, and a second transverse profile attached to the second end of the panel. A force-applicator is located between the first transverse profile and the second transverse profile. The force-applicator is configured to apply a force between the first transverse profile and the second transverse profile, thereby applying a tension force to the panel. The force-applicator defines a longitudinal axis displaced from the major surface of the panel, the force-applicator including two parts capable of being moved, one with respect to the other, connected to one another by a sliding connection controlled by a spring.

Abstract: An inexpensive, lightweight, reusable and detachable or removable insulation device for residential and commercial dwellings and similar heated structures. The device has an inner-portion insulating pad adapted to fit inside of a typical entrance or window unit framing. The device further has an outer-portion insulating pad adapted to overlap the window or entrance framing. The outer-portion insulating pad is provided fasteners so as to be secured to the building wall structure outside of the framing and surrounding the window or entrance framing by. During cold weather months, the present invention will greatly restrict warm air from escaping between small crevices in inept window systems by fitting firmly into window framing using a insulating material, thus creating a thermal barrier and improving the efficiency of the furnace by reducing the demand for electricity or fuel consumption.

Abstract: A screen frame is made by joining four (three or more) screen frame segments together at corners to form a generally rectangular or multi-sided screen frame. Corner joint inserts are placed within each corner of the four screen frame segments and the inserts are spot welded to adjoining screen frame segments to provide a sturdy and rigid screen frame. The screen frame segments are metal extrusions having two parallel flanges extending from a generally square shaped hollow body. A metal screen is secured in the screen frame by spot welding the screen between the flanges of the screen frame segment. The resulting screen frame and screen provides a long-lasting, corrosive resistant, and rigid frame and screen for positioning in window or door frames which can withstand damage from intruders, projectiles, and environmental stresses.

Abstract: A privacy screen is configured for use with systems furniture and the like, such as post and beam arrangements that spatially partition an open office space into multiple workstations each having an interior with an opening into an adjacent space. The privacy screen is shaped to enclose a substantial portion of the opening of an associated workstation, and includes a generally flat lower portion, and a bowed upper portion that extends outwardly from the interior of the workstation to provide within the interior of the workstation a sense of spatial openness, as well as enhanced air and light influx, without detracting substantially from useable space on the opposite side of the privacy screen. The privacy screen may be constructed from a woven fabric with a single layer at the upper portion for greater visual porosity, and two layers at the lower portion for visual privacy.

Abstract: A skylight shade formed of a frame and engageable with the sides of a skylight opening and a filter sheet supported by the frame. The frame is formed from a plurality of adjustable rods which each have an outer member and an inner member which is adjustably received within the outer member and engages a spring therein. The outer member has a aperture extending perpendicularly therethrough adjacent one end and receives an end of an inner member of another rod therein. The filter sheet has attachment sleeves which are received around the rods for attaching the filter sheet to the frame. The rods contract via springs to allow each rod to be received within the skylight opening and are forcibly biased via springs the rod into secure engagement with the sided of the skylight opening.
