A door apparatus for closing an access opening and to a parking apparatus equipped therewith. The door apparatus has two vertically aligned guide rails and an inner and an outer door element which are each movably mounted in/on a vertically aligned inner or outer guide of the guide rails. In a closed position, the inner door element is arranged in a first region of the access opening which is situated lower than a second region in which the outer door element is arranged. In an open position, the inner and the outer door element are arranged in a third region of the access opening which is situated higher than the first and the second region. Furthermore, the door apparatus has a locking element and a coupling element.

A hidden insect screen system for tilt-to-clean, double hung windows whereby raising the bottom sash (104) causes resultant opening to fill with insect screen (115a) dispensed from an ordinary self-storing roller mechanism (114) mounted inside bottom rail (109) of said sash and whereby lowering the upper sash (105) causes resultant opening to fill with insect screen (115b) dispensed from an ordinary self-storing roller mechanism (122) mounted inside window head frame (103), all furnished such that vertical edges of the screens are protected from insect passage by contacting weatherstrip-like edge seals (127), and arranged such that insect protection is maintained with minimal interruption when each sash is tilted and its glazing is cleaned, the lower end of the upper screen being attached so as to be quickly repositioned from top to bottom of said upper sash.

The invention provides for an article of manufacture, being a sealing pad (410a, 410b, 510a, 510b, 610a) for providing resistance (obstruction) to infiltration of matter and/or energy into pre-manufactured products, including such as windows, doors and appliances. The invention also provides for a method of employing the sealing pad (410a, 410b, 510a, 510b, 610a) to provide location targeted and value added obstruction (resistance) to such infiltration into pre-manufactured products, in response to performance of infiltration testing.

Disclosed are novel forms of operable and fixed windows capable of at least one or more of: producing an electrical current utilizing a transparent or semi-transparent solar collecting coating or film on a pane, and selectively changing one or more of opacity and tint of one or more electrochromatic layers in the window. Some embodiments disclose a scaffold assembly to enclose the perimeter of the substrate and one or more transparent solar cells or electrochromatic layers, or transparent solar cells and electrochromatic layers. Various structural and electrical configurations are disclosed satisfying kinematic demands of operable windows. Wired and wireless configurations of the windows are contemplated as are self-powered versions whereby the transparent solar collector or wireless power powers electrochromatic functions. Also disclosed are self-powered and self-contained glaze units with control wirelessly or from user interface controls on an indoor facing pane. Also disclosed are other smart window functions.

A window system for use in windows, sliding glass doors, skylights, casement windows and other openings in a building. The window system enables different windows of the same building to be individually customized for different impacts of coastal area weather and security concerns and also have the same external appearance despite employing various window protection steps. Panels, interior or exterior, are secured to the header and sill. Windows may be covered with exterior panels or include interior panels or impact resistant glass when the window is high on the building, or where security is a concern Windows including casement windows and other building penetrations may also accommodate interior panels, in combination with exterior protection. The window framing may have a uniform exterior appearance, notwithstanding different levels of protection.

A fenestration system may comprise a closure element, such as a door or window. The closure element is movable relative to a frame between open and closed positions. The frame surrounds a fenestration opening, such as a doorway. The fenestration system may also comprise a carrier mounted to the closure element and movable relative to the closure element between extended and retracted positions. A weather strip is attached to the carrier and arranged to contact the frame in the extended position of the carrier. One or more retraction magnets may be arranged to exert a first magnetic force on the carrier to move the carrier into the retracted position in the open position of the closure element. One or more extension magnets may be arranged to exert a second magnetic force on the carrier to move the carrier into the extended position in the closed position of the closure element.

A window balance assembly may include a carrier, a spring element, and a mounting bracket. The spring element may include first and second portions. The first portion may be coupled to the carrier. The mounting bracket may engage the second portion of the spring element and may selectively engage the carrier.

Disclosed are novel forms of operable and fixed windows capable of at least one or more of: producing an electrical current utilizing a transparent or semi-transparent solar collecting coating or film on a pane, and selectively changing one or more of opacity and tint of one or more electrochromatic layers in the window. Some embodiments also disclose a robust scaffold assembly utilized to enclose the perimeter of the substrate and one or more transparent solar cells or electrochromatic layers, or transparent solar cells and electrochromatic layers. Various structural and electrical configurations are disclosed to satisfy the kinematic demands of operable windows. Wired and wireless configurations of the windows are contemplated as are self-powered versions whereby the transparent solar collector or wireless power powers the electrochromatic function. Also disclosed are self-powered and self-contained glaze units with wireless control or control from user interface controls on an indoor facing pane.

This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity. Pre-wired spacers improve fabrication efficiency and seal integrity of insulated glass units. Electrical connection systems include those embedded in the secondary seal of the insulated glass unit.

A window balance assembly may include a carrier, a spring element, and a mounting bracket. The spring element may include first and second portions. The first portion may be coupled to the carrier. The mounting bracket may engage the second portion of the spring element and may selectively engage the carrier.
