A device may limit opening of a sash hingedly coupled to a master frame, and includes: a bracket attached to the sash; a first arm having a first end pivotally coupled to the bracket; a second arm having a first end pivotally coupled to the first arm's second end; means for biasing the second arm into a retracted position; and a release assembly. The release assembly is secured to the master frame and includes a hook pivotable between a first position and a second position, which, in the first position, may be releasably received in an opening in the second end of the second arm when the second arm is in the retracted position, as the sash is closed and received within the master window frame The second arm is disengaged from the hook, permitting full opening of the sash, when the hook is pivoted into the second position.

In one aspect, the present invention relates to a structural assembly including a first frame member hingedly coupled to a second frame member. A support member extends outwardly from the first frame member. At least one glazing panel is disposed above the support member. A thermal clip is coupled to the support member. The thermal clip insulates the support member from a building exterior. The support member extends less than an entire length thereof and reduces loss of thermal energy from a building interior to the building exterior via the support member.

A trash collection assembly may include a dumpster housing which may house therein a dumpster to provide a more desirable aesthetic appeal. A garbage truck may be configured to lift the dumpster out of the dumpster housing without the need for the garbage truck driver to get out of the truck. A cover of the dumpster may open and close automatically respectively during the removal of the dumpster from the housing and return of the dumpster to the housing.

A main support frame is formed from sections of a plastic extrusion and has opposite side portions with peripheral recesses receiving an inner sash unit and outer sash unit each having a frame formed from sections of a plastic extrusion and supporting an insulated glass unit. Hinges support the dual sash units for pivotal movement between open and closed positions, and gear connected telescopic link members connect the main frame to the sash frames for simultaneous movement. A lock system includes a handle on the inner sash unit for moving straps with studs on the sash frames through a connector mechanism mounted on the main frame for simultaneously locking and releasing both sash units and for releasing only the inner sash unit. A screen and/or mini-blind may be supported between the sash units, and the window system with dual sash units may be constructed in various forms.

A window assembly having a first sash and a second sash mounted to a window frame, the first and second sashes arranged along different vertical planes within the window frame to resemble the appearance of a double hung window. The window assembly further includes a hinge mechanism coupled to the window frame and to the second sash, hinge mechanism operable to guide the second sash away from the first sash to accommodate an outwardly swinging motion of the second sash in a similar fashion as a conventional awning window. The first sash may be fixed relative to the window frame, or may alternatively be moveable upwardly or downwardly relative to the window frame.

A trash collection assembly may include a dumpster housing which may house therein a dumpster to provide a more desirable aesthetic appeal. A garbage truck may be configured to lift the dumpster out of the dumpster housing without the need for the garbage truck driver to get out of the truck. A cover of the dumpster may open and close automatically respectively during the removal of the dumpster from the housing and return of the dumpster to the housing.

A door assembly may include a first sidelite configured to be operably coupled to a first doorjamb, a second sidelite configured to be operably coupled to a second door jamb where the first and second sidelites are disposed in a common plane and define a door opening between the first and second sidelites, a first sliding panel, a second sliding panel where the first and second sliding panels are movable from a closed position disposing the first and second sliding panels to block access through the door opening and an open position in which the first sliding panel is proximate the first sidelite and the second sliding panel is proximate the second sidelite, a first partial door panel, and a second partial door panel. The first and second sliding panels are disposed in a second plane parallel to the common plane in both the open and closed position. The first and second partial door panels are operably coupled to the first and second sidelites, respectively, via hinge assemblies. The first and second partial door panels have a closed state in which the first and second partial door panels are each disposed in the common plane blocking access through the door opening, and an open state in which the first and second partial door panels are each disposed out of the common plane.

A closing body allows closing and opening an access opening or a passage of a room in case of a pressure difference between an interior and exterior of the room. A closing fitting set and a door leaf are disclosed, by means of which closing fitting set and door leaf a closing body can be formed. The closing body is in the form of a pivotable door, a pivotable window or a pivotable flap. A valve device is provided on the closing body, which valve device effects a temporary pressure equalization during the opening or closing of the closing body. The valve device is in the form of a valve flap, and a release mechanism is provided, which opens the valve device. A locking fitting is provided for the closing body, and the release mechanism is coupled, for actuation, to the locking fitting of the closing body.
