Description

Roof window

The proposed group of technical solutions relates to the field of ground construction and can be used, in particular, in the manufacture of skylights intended for installation on pitched or flat roofs of buildings and structures, both in the construction of new residential buildings of modern architectural forms, and in the overhaul of old buildings. and structures, including when the attic space is reconstructed in order to increase the living space. The proposed solutions can be implemented as separate windows or as combinations of the proposed window designs in one frame with blind and / or opening parts.

Known solution "Window structures, especially attic" (Fensterkonstruktion, insbesondere Dachfensterkonstruktion), described in document DE202006014581, publ. 03/13/2008 The construction of a roof window made of metal, mainly aluminum, profiles, connected by insulating rods, is described. In addition, the design of the window from the side of the room allows you to leave the metal profiles as they are or use decorative wooden linings in accordance with the requirements for the design of the room and the window structure. The design is intended for use primarily with post-transom glazing systems.

Known solution "Window system for installation on an inclined surface of the building, providing improved load transfer" (WINDOW SYSTEM FOR MOUNTING IN AN INCLINED SURFACE OF A BUILDING PROVIDING IMPROVED LOAD TRANSFER), described in document US20160222668, publ. 08/04/2016 Window system for installation on an inclined surface of a building, and the specified window system comprises a frame structure of a frame and a sash structure, each of which forms a substantially rectangular element with an internal opening, and where a transverse element extending below between the side elements of the sash structure , forms a supporting element for the insulating glass unit and acts as a support for the insulating glass unit to transfer at least part of its load to the side elements of the sash structure. At least one support for the insulating glass unit can be mounted on the supporting element. Window frame and sash constructions are made of special profiles.

As a prototype, the known solution "Window for a roof, mainly for a flat roof" (ROOF WINDOW PARTICULARLY FOR FLAT ROOFS), described in document EP3348737, publ. 07/18/2018 The construction of the roof window is equipped with a sash equipped with a glass unit. The outer glazing sheet of the double-glazed unit covers the outer surface of the sash frame, the inner sheets of the insulating glass unit are located in the sash opening. In this case, photovoltaic cells are located along the edge of the outer sheet of the glass unit. The sash frame and window frame are made of special profiles. The sash structure contains facing elements along the perimeter, which cover the place where the sash adjoins the frame from direct rainfall.

The disadvantages of the prototype and other known designs include the complexity of the design due to the use of frames made of special profiles in the design of the window, as well as insufficient reliability due to the possibility of breaking the insulation and depressurization at the junction of the elements of the prefabricated structure of the sash and glass units.

The skylights described above can also be made in a non-opening version without sashes. In these versions, the windows can be used on sloped and horizontal roofs as skylights or skylights. One of the variants of execution, for example, is described in patent US10087635 "Curb-mounted skylight", publ. September 28, 2017

Known hinge connection type "friction scissors" used in various window designs and facade glazing systems. This type of connection is also called a friction loop or friction bearing. The design of such connections is described, for example, in patent RU57787 "FRICTIONAL HINGE FOR OUTWARD OPENING WINDOWS", publ. 27.10.2006 The hinge joint of the "friction scissors" type is a cantilever-lever mechanism containing a base intended for fastening to a window frame, and a cantilever element intended for fastening to the window sash frame, fixed to the base with the possibility of folding into position "Closed" and unfolding to the "open" position through a system of intermediate levers, hinges and movable joints, and the base has longitudinal guides for moving the carriage, to which the intermediate levers are pivotally attached. In the design of the window, these connections are used in pairs and can be installed in the upper part of the window on the sides of the sash in the space between the window frames and the sash to enable the sash to open outward. When the sash is opened, its frame rotates around a horizontal axis, which in turn simultaneously moves out and down from its original position when the sash is closed. The design of such a hinge joint allows the window sash to be fixed in the desired intermediate or extreme position due to friction in the hinged and movable joints of the intermediate levers or, in special cases, due to auxiliary retainers.

Known gas springs, or the so-called "gas lifts", widely used in furniture, window, automobile and other structures with moving parts. A gas spring, most often, is a cylinder with a piston and a rod, the internal cavity of which is filled with gas or a mixture of gases and a liquid under pressure, the piston has the ability to move longitudinally in the cylinder, while the gas under pressure creates a pushing force of the piston. Gas springs, in particular, are used to facilitate the opening of hatches, covers and similar parts of various designs, as well as to hold moving parts in the extreme "open" positions. In addition, gas springs, due to the gas pressure acting on the piston with the rod, have a damping effect, resisting the movement when the moving parts of the structures return to the initial “closed” position. A wide range of gas springs allows you to choose an option suitable in terms of size, force and other parameters. One of the options for a gas spring is described in the patent RU16616 "GAS SPRING", publ. January 20, 2001

The gas spring facilitates the opening of the sash, and also softens its closing, and helps to hold / maintain the sash in the intermediate opening positions, between the extreme positions "open" and "closed".

The use of typical gas springs and "friction scissors" greatly simplifies the design of the window.

The use of widespread standard T, L and Z-shaped plastic profiles for the window frame and sash frame, as well as L and Z-shaped profiles of the cladding element made of sheet material, greatly simplifies the construction of the window and facilitates its manufacture.

The design of the sash frame as a non-separable integral whole with a glued-in glass unit and a facing element simplifies the design and increases the reliability of the window by increasing its insulating properties and reducing the likelihood of a breach of sealing.

The use of a hinged joint of the "friction scissors" type, a pair of which is installed in the upper part of the window on the sides of the sash frame in the opening between the window frame and the sash frame, simplifies the design and ensures reliable positioning of the sash relative to the frame, as well as the ability to fix the sash position in intermediate and final position "open" due to frictional forces in the pivotal and movable joints of the intermediate levers "friction scissors" or with the help of additional clamps or devices.

When the sash is opened, its frame rotates around a horizontal axis, which in turn simultaneously moves outward and downward from its original position when the sash is closed. The trajectory of the sash movement makes it possible to compact the drainage element installed above it.

The advantages of the proposed options for the construction of the roof window are a relatively simple manufacturing technology, the availability and widespread availability of components required for production, high reliability and durability, due to the minimum number of detachable connections of structural elements and the use of modern high-quality materials, ease of installation of the window at the installation site on the roof.
