A latch is provided for use on a pivotable sash window of a single-hung or double-hung sash window assembly to releasably secure the window to the master frame. The latch comprises a latch-bolt slidably mounted within, and biased relative to a housing. The housing is adapted to be installed into the top rail of the sash window through an opening in the stile and top rail, which has a periphery contoured to match the housing end profile. The latch bolt, while maintaining an aesthetically appealing external appearance, is configured to incorporate a cantilevered member which only becomes visible when biased to an angled position where it maintains engagement of the latch housing with the edge of the top wall of the rail during window deformation resulting from high wind loading. The cantilevered member ensures integrity of the latch installation under high wind load conditions typically experienced during extreme weather phenomena.

The invention relates to an elastic force tensioned window screen which belongs to the field of anti-mosquito devices for windows in buildings and aims at solving the problem of poor combination property commonly existing in the traditional window screens. The invention has the technical scheme that an elastic force assembly is arranged above the bottom face of the upper frame of the window screen or/and under the top face of the lower frame of the window screen, and generally, the elastic force assembly is provided with a secondary frame and is provided with a baffle part if necessary. When the window screen is in a working state, the side frame of the window screen reaches the tension intensity of the set wind resistance through vertical tension generated by pull force in the perpendicular direction. The position limiting function can also ensure no oversize seam of the side frame of the window screen in storm wind. The side frame of the window screen can be coiled so that the window in a building can be opened and closed after collecting or lifting the window screen. Connecting parts for assembly are generally hanging type, sleeve type and inserting type fittings, which are easy to install and disassemble and are prevented from falling. The invention is suitable for out-opening windows, sash windows and the like in buildings.

The invention discloses a sealing structure for a sash window. The sealing structure comprises a window sash and a window frame, wherein the window sash is arranged in the window frame; one side face, in perpendicular contact with the window frame, of a frame of the window sash is provided with a groove; the window sash is provided with a protrusion part matched with the groove; a first elastic piece and a second elastic piece, which extend along the perpendicular direction are arranged in the groove; the first elastic piece is arranged on the top surface of the groove and is positioned between contact surfaces of the frame and the window frame; the second elastic piece is arranged on the inner side wall of the groove; after the window sash and the window frame are closed, the second elastic piece is pressed to the outer side wall of the protrusion part. The sealing structure has the beneficial effects that the first elastic piece realizes a basic blocking function to realize a horizontal seal of the window frame and the window sash; the sealing direction of the second elastic piece is perpendicular to the sealing direction of the first elastic piece, so that a longitudinal seal of the window frame and the window sash is realized; the two seals are matched for use to achieve better sealing effect and realize more thorough soundproof, thermal insulating, waterproof and dustproof functions.

The invention provides a bottom framework of a flat window, the bottom framework comprises three plate bodies which are mutually parallel and arranged at intervals, two inclined plates which inclinedly connect two adjacent plate bodies and more than two check valves which are respectively arranged on two plate bodies, wherein, the check valves can only be pivoted and opened on one direction, thereby leading liquid accumulated in the bottom framework to be capable of flowing along the inclined plates and further ejecting the check valves to flow to the outside of a building; moreover, air at the outside of the building can not be blown into the interior of the bottom framework from the check valves, even the check valve which is arranged to be near to the outside of the building is opened to cause the air to be blown into a window frame therefrom, the bottom framework can still block the air and noise by the other check valve, thereby simultaneously achieving the effects of drainage and sound insulation.

A sash window fastener includes lock and latch assemblies, and a fitting. The lock mounts upon the meeting rail, and includes a pivotable cam to engage a keeper on the master frame, and a pivotable arm acting as a follower. The arm interconnects with the latch within the meeting rail, so cam rotation controls arm positioning—causing translation of the latch. The cam can occupy three positions causing three corresponding latch positions: an extended position securing the cam to the keeper, with the latch engaging the master frame to prevent tilting, and also receiving a post of the fitting therein to further secure the window against impact loading; a first retracted position disengaging the cam from the keeper, and permitting sliding of the window into an open position that also elevates the latch member above the post; and a second retracted cam position causing latch member retraction that permits tilting.
