The present invention consists of a frame for turn & tilt or projecting doors or windows, which achieves a minimalist exterior appearance with a central profile of 18 mm, wherein the offset of the alignment of the external glass with the internal glass is now used, creating a common central outer profile of 18 mm, and wherein the thermal and acoustic performance and the resistance to water, air and wind permeability are further improved. The frame, object of the present invention, is preferably made of aluminum with thermal break for the manufacture of doors and/or windows, it is applied in a door or window opening of a building and it consists essentially of at least one fixed rim (3) and at least one movable leaf (1) and at least one fixed leaf (4), wherein at least one movable leaf is glued to the glass (2) in all its perimeter.

In a tilt and turn or fixed frame window, a meeting rail unit is provided in the sash unit, dividing the sash unit vertically into an upper sash portion and a lower sash portion, the meeting rail unit having an upper portion for securing an upper glazing unit in the upper sash portion, and a lower portion for securing a lower glazing unit in the lower sash portion. An upper glazing unit secured in the upper sash portion of the sash unit, and a lower glazing unit secured in the lower sash portion of the sash unit. The meeting rail unit is configured to provide an offset between the upper glazing unit and the lower glazing unit in a direction perpendicular to the horizontal axis and to the vertical axis. An outside surface of the upper sash portion and an outside surface of the lower sash portion lie on the same plane.

A single-hung tilt-to-clean window frame of otherwise standard configuration is furnished with a non-sliding upper sash and a vertically sliding lower sash with each sash having typical tilt-to-clean hardware. When the lower sash is opened and adjusted up/down, insect screen (331) attached to the bottom of the lower sash is dispensed from a self-storing roller unit (330) hidden inside the window sill, automatically filling the ventilation aperture. Thus, vision-restricting screening is out of sight until actually required. Also, the cold wind, muggy air or precipitation that can hinder cleaning operations are blocked by an impervious membrane (334) stretched over the window's opening, before cleaning begins, by way of a handle (343) attached to cables (340) pulling a rod (336) moving a tube (335) placed behind a fold in the membrane.

A bollard that supports a door with a top bearing, middle bearing and bottom bearing with the middle and bottom bearing offset from the bollard and a rigid structure molded in the door.

The invention relates to a frame structure, such as a window sash or a frame for a window or door, comprising a core made from at least one core member made from expanded polystyrene (EPS) with a density of 80-200 kg/m.sup.3 and a shell of polyurethane (PUR) encasing the core. The core may include a plurality of core members, some of which may be made from a different material.

A hinge for a pivoting window or door with a frame and a leaf that can tilt with respect to the frame, whereby the hinge includes a frame part fastened to the frame and a leaf part fastened to the leaf, with a scissor mechanism between the frame part and the leaf part on which the leaf part is hingeably affixed around an axis of rotation, whereby the scissor mechanism comes into operation in a first phase of the tilting movement of the leaf, so that the axis of rotation moves in a direction essentially transverse to the plane of the frame into a locking position whereby the axis of rotation is at a distance from the frame such that the axis of rotation is a fixed axis around which the leaf can tilt further in a second phase of the tilting movement of the leaf.

The present invention consists of a frame for turn & tilt or projecting doors or windows, which achieves a minimalist exterior appearance with a central profile of 18 mm, wherein the offset of the alignment of the external glass with the internal glass is now used, creating a common central outer profile of 18 mm, and wherein the thermal and acoustic performance and the resistance to water, air and wind permeability are further improved.

A door is formed into a folding door by dividing the door into two parts to left and right, that is, a hanging door and a door-end door pivotally supported by the hanging door, and the door-end door is used as the pressure difference mitigating mechanism, and the two doors are integrally operated in a normal time, while if a pressure difference is generated, the door-end door can be first opened in order to reduce an opening force, and the door device with a pressure difference mitigating mechanism with excellent operability is provided. A handle position, a latch position, and a torque are adjusted for a handle for door opening/closing, a door closer, a hinge closer for rotating the door-end door with respect to the hanging door, a latch A of the door-end door to a door frame, and a latch B of the door-end door to the hanging door.
