Overly roof window

Description of the invention

The subject of the invention is an overlay roof window, intended to be mounted on a frame protruding from the roof slope and being a part of its structure. The window can be unopened or opened. The window according to the invention is used both in so-called flat roofs and in sloped roofs.

State of the art. It is known from the patent specification US 7624547 (B1) a roof window intended for mounting on a frame protruding from the roof, having a glazing unit consisting of two panes connected by a spacer frame. The glazing unit is mounted via a frame overlapping the upper surface of the outer pane. This solution makes it difficult for rainwater or melted snow to run down the pane, because this water stops on the frame protruding above the pane, adjacent to the lower edge of the pane. Stopping water flow occurs especially in windows installed in flat roofs or with a slight slope.

The essence of the solution. The overlay roof window is intended for installation on a framing protruding from the roof slope and being a part of its structure. It is equipped with a glazing unit consisting of at least two panes separated by a space filled with gas, and it has a support frame for a glazing unit, which is made of a section with a support wall and a curtain wall surrounding the glazing unit. Between the support wall of the section of the supporting frame of the glazing unit, and the edge zone of the lower glazing unit, along all the edges of this glazing, there is an adhesive joint, which creates a compact and inseparable structure of the glazing unit and its supporting frame.

The distance from the support surface of the roof window, on the framing protruding from the roof slope, to the most protruding edge of the curtain wall of the section of the supporting frame of the glazing unit is not greater than the distance from the supporting surface of the roof window to the outer plane of the glazing unit. There is an adhesive and sealing joint between the glazing unit and the curtain wall. Preferably, the edge of the curtain wall of the support frame section ends slightly below the outer surface of the glazing unit, as a result of which the outer surface of the adhesive and sealing joint is inclined with respect to the outer surface of the glazing unit, creating a chamfer of the outer edge of the roof window. The individual panes in the glazing unit, in particular, have a rectangular shape, the widths of these panes being identical throughout the glazing unit, and the lengths of these panes being identical throughout the glazing. The window is designed to be installed in flat roofs as well as in steep roofs, and the full range of inclinations is from 0 to 85 degrees.

The section of the supporting frame of the glazing unit, in addition to the supporting wall and the curtain wall surrounding the glazing unit, also has a bottom curtain wall, which is located below the supporting wall, on the extension of the curtain wall. The lower curtain wall of the section of the supporting frame of the glazing unit is surrounded by a frame protruding from the roof, protecting it against the influence of weather conditions.

Advantageously, the section of the supporting frame of the glazing unit has a rib located below the supporting wall and facing the same direction, as a result of which there is a fixing groove between the rib and the supporting wall. A profile strip is embedded in this groove for fixing window accessories located inside the room with the roof window, for example an internal roller blind or a strip shutter. Preferably, the profile strips extend along all sides of the glazing unit, forming a mounting frame for the indicated window accessories.

In the first variant of the invention, the overlay roof window is not opened, and its fastening frame for the window accessories, placed under the glazing unit, rests on the frame protruding from the roof slope. Preferably, there is a flat gasket between this fastening frame and the frame projecting from the roof. The non-opening overlay roof window is attached to the roof by means of intermediate fasteners, such as screws or nails, which, while passing through the openings in the bottom curtain wall of the section surrounding the glazing unit, are embedded in the framing protruding from the roof slope, which is a part of the roof structure.

In a second variant of the invention, the overlay skylight also does not open. It differs from the first variant in that it additionally has a frame mounted on a framing protruding from the roof slope, attached to this framing with, for example, threaded fasteners. A fastening frame for window accessories is placed under the glazing unit, which rests on the frame. Preferably, there is a flat gasket between this fastening frame and the jamb. Glazing package

The PL 229 602 B1 is attached to the frame by means of intermediate fasteners, such as screws or nails, which, while passing through the openings in the bottom cover wall of the section surrounding the glazing unit, are embedded in the frame of the overlay roof window.

In a third variant of the invention, the overlay skylight also does not open. This window has a casing mounted on a framing protruding from the roof slope, as in the second variant of the invention. However, it does not have a fixing frame for window accessories, and instead, the supporting wall of the profile of the supporting frame of the glazing unit extends towards the center of the package, overlapping the frame. Preferably, there is a flat gasket between the supporting wall of the support frame section surrounding the glazing unit and the frame. The glazing unit is attached to the frame, identically as in the second variant of the invention.

In a fourth variant of the invention, the overlay roof window is opened. This window has a casing mounted on a framing protruding from the roof slope, as in the second variant of the invention. The glazing unit with its supporting frame is part of the movable sash of this window, also having a mounting frame for window accessories, identical to the first and second variants of the invention. The window sash is connected to the frame by means of hinges, which on the sash side are embedded in the mounting frame for window accessories. In the closed state of the window, a flat gasket is preferably provided between this fastening frame and the frame.

In a fifth embodiment of the invention, the overlay sunroof is also openable. This window has a casing mounted on a framing protruding from the roof slope, as in the second variant of the invention. The glazing unit with its supporting frame is part of the movable sash of this window, which (as in the third variant) does not have a fixing frame for window accessories, while the support wall of the section of the supporting frame of the glazing unit extends towards the center of the package, overlapping the frame. The window sash is connected to the frame by means of hinges, which are attached to the section of its supporting frame on the sash side. In the closed state of the window, a flat gasket is preferably provided between the supporting wall of the support frame section and the frame.

In a sixth variant of the invention, the overlay roof window is non-opening and its structure is the simplest of all the variants. This window has neither a frame nor a frame for window accessories, while the support wall of the section of the supporting frame of the glazing unit extends towards the center of the packet, overlapping the framing protruding from the roof slope, which is part of its structure. In the supporting wall of the section of the supporting frame of the glazing unit, on its lower surface, the window has a gasket, preferably mounted in the groove. The window is fixed to the roof, as in the first variant, by means of intermediate fasteners, such as screws or nails, which, while passing through the openings in the bottom cover wall of the profile surrounding the glazing unit, are embedded in the framing protruding from the roof slope.

In variants of the overlay roof window according to the invention, equipped with a frame, i.e. variants: the second, third, fourth and fifth - thermal insulation covers, mounted on the outer side surfaces of the frame, can be additional equipment of the window. Preferably, the thermal insulation caps extend towards the roof slope, as a result of which they also overlap the side surfaces of the framing protruding from the roof, also insulating this zone.

Beneficial Effects of Using the Invention. The overlay roof window according to the invention, thanks to the use of the load-bearing frame of the glazing unit, which does not extend above the upper surface of the outer pane, allows rainwater or melted snow to flow freely on the pane, which facilitates keeping the pane clean and reduces the frequency of necessary window cleaning operations. This advantage is particularly important in non-opening windows, which require access to the roof to clean.
