The present invention discloses a casement window positioning slide brace, which is mainly characterized in that: sliders are divided into a static slider (9) and a movable slider (5). The movable slider and the static slider can attract each other during mutual contact; the other end of a short strut (3) is hinged on the movable slider; the other end of a middle strut (2) is hinged on the movable slider. The present invention solves the problem that: after a casement window is opened, as the window has gravity and window sashes are blown by the wind with intensity, the sliders of the casement window automatically slide down to close the window. Due to the fit of the static slider and the movable slider of the present invention, after the casement window is opened, the casement window is fixed on some position; the wind with common intensity cannot cause the sliders to slide, and only the action with certain external force can allow the movable slider to be separated from the static slider, so as to achieve the objective of closing the window or changing angles.

A locking mechanism for a casement window assembly includes a housing adapted to be mounted on the window assembly, an actuator operably connected to the housing and pivotable about a fulcrum, and a linkage member having a first channel and a second channel. The housing has an elongated opening having opposed ends. The actuator includes an actuator body having a first pin and a second pin located thereon. The linkage member is connected to the actuator such that the first pin is received in the first channel and the second pin is received in the second channel. Pivoting the actuator about the fulcrum causes the first pin to move within the first channel and the second pin to move within the second channel, moving the linkage member along the opening, from one end of the opening to the other end of the opening.

The inner and outer heat insulation hollow casement window structure is simple in structure, convenient to manufacture and assembly; the contact area between an aluminum profile and atmosphere tends to be zero, the heat exchange of an aluminum alloy framework caused by air convection can be prevented, thereby improving the heat insulation performance and achieving the purpose of saving energy.

A magnetically attachable window screen system comprising,

a rectangular casement window comprising a casement window frame for removably attaching a rectangular window screen, the casement window frame comprising four window frame sides,

the four window frame sides comprising a lower horizontal frame side, an upper horizontal frame side and two opposing vertical frame sides, each window frame side comprising a front perimeter wall and a side perimeter wall, at least one frame magnet attached to the casement window frame at least partly behind the plane defining the front perimeter wall or the plane defining the side perimeter wall, at least one support on the casement window frame for supporting the window screen, the window screen comprising a screen frame comprising four screen bars, the four screen bars comprising a lower horizontal screen bar, an upper horizontal screen bar, and two vertical screen bars, the window screen further comprising at least one screen magnet attached to the window screen frame and positioned to magnetically co-operate with the at least one frame magnet attached to the casement window frame.

A casement window assembly includes a hinged sash window pivotally mounted within a window frame. The casement window assembly has a snubber mechanism. The snubber mechanism has a first member connected to the window frame and a second member attached to the sash window. The snubber members have cooperative structures that cooperatively confront each other in spaced relation to selectively engage each other to prevent undue bowing of the sash window when subjected to high stresses such as from high wind loads.

A rack and pinion are mounted on a casement window frame to operate a vertically disposed polymeric latch keeper. The moveable rack includes a plurality of teeth which are engageable with latch keepers spaced therealong. The pivotable window section includes latches which are rigidly affixed thereto. Thus when the window is closed a pinion can be rotated and thus drive the rack to engage the latch keepers into mating engagement with the latches for security and wind load resistance. The method of installation utilizes frangible spacers affixed to the latches for quick and easy alignment with the latch keepers.

The invention relates to a ventilating dead window, which is characterized in that the window includes an internal window frame and an external window frame which are arranged inside a window aperture, and a space is left between the two window frames; a plurality of vertical mullions are arranged at the opposing positions on the two layer of window frames, and a vertical glass partition is arranged on each of two opposing vertical mullions and divides the space between the two window frames into a plurality of independent cavities, and a hole is arranged on the vertical glass partition to communicate with the neighboring cavities; at least one swing-in casement window is arranged on the internal window frame at one side, and at least one swing-out casement window is arranged on the external window frame at the other side. The invention divides the cavities between the two window frames into a plurality of cavity bodies, at the same time air inlets are arranged at the different positions of each glass partition; therefore the outside air experiences a plurality of expansions when passing each cavity and can reduce noise in the process of entering the room. The invention can be widely applied to the buildings which are near to railway, highway or airport where the noise environment is more serious.
