Description

The invention relates to window structures.

A rotary casement window is known, containing a frame and a hinged sash attached to one side of the frame using hinges, a means for locking/unlocking the hinged sash relative to the frame, configured to slide along the second side of the frame, and an associated handle mounted on the frame, as well as a lever located between the second side of the frame and the hinged sash, ensuring reliable installation of the sash in its open position outward at a limited angle of rotation relative to the frame in order to prevent people from leaning out of it (RU 2643983, IPC E05F 11/24, published 02/06/2018).

The disadvantage of such a window is its low light transmission due to the presence in its design of an impost and sash frame parts that are large in size across the width of the window. Another disadvantage of the known design is its high mass.

In addition, the known window, like most hinged window structures, does not sufficiently protect people from falling out of the window, which is especially important for high-rise buildings.

While tilting window structures contribute to a greater extent to saving people's lives, they are, as a rule, equipped with complex and expensive tilt-and-turn fittings, for example, such as those described in the decision on patent RU 2329365, IPC E05D 15/52, publ. . 07/20/2008.

Also known are hinged casement windows with the so-called false impost, in which all the locking and turning fittings associated with the handle are built into the inside of the frame of one sash, performing the function of an impost, and the fittings of the frame of the second sash with a hinge serve as a lock (see page on the Internet “Shtulpovyye windows”, https://okna-dom.net/shtulpovyye-okna/).

In such windows, light transmission is increased due to the absence of an impost, but the risk of falling out of the window remains and even increases, since the width of the window opening increases when both window sashes are open.

The technical problem solved by the invention is to create a window structure with improved performance properties, including ensuring its safety during use.

The technical result, aimed at solving the above-mentioned technical problem, consists of an even greater, in comparison with the analogue, light transmission and lighter weight of the window, by reducing the material consumption of both the polymer frame of the window sash itself and the locking mechanism included in it (hardware), which is positive will affect the final cost of the window.

The named technical result was achieved in the invention using the following set of features.

A tilting window contains a window frame connected by means of hinges to a folding sash, which consists of a double-glazed window enclosed in a frame made of interconnected outer and inner parts. The inner part of the frame is equipped with a mechanism for controlling the position of the flap, including a handle with a pin, the free end of which is connected to a rocker arm, on which a pin is attached, connected to a rod that can be moved in the vertical direction. At the end of the rod, an inclined protrusion is formed, configured to interact with a groove corresponding to it in shape, formed on the edge of the plate, made with the ability to move in the horizontal direction. Said plate is equipped with a latch configured to engage with a protrusion formed on the window frame.

The window frame is made with a closed load-bearing element consisting of metal profiles connected in the corner sections of the frame with fastening plates.

The edges of the window frame and flap frame facing the glass unit are located at the level of the edges of the spacer frames of the glass unit.

A locking element is fixed to the rod and is designed to interact with a stopper-limiter mounted on the window frame. The sides of the window frame and the flap frame are connected to each other by two hinged strips.

The invention is illustrated by drawings.

Figure 1 schematically shows the window in the maximum permissible tilted position.

Figure 2 schematically shows fragments of an axial section of a window.

Figure 3 shows section A-A; B-B in figure 2.

Figure 4 shows a section B-B in Figure 3 for three positions of the double-glazed window: a) closed, b) slot ventilation, c) maximum opening.

Figure 5 shows a section GG in figure 2.

Figure 6 shows a section D-D in Figure 3.

The tilt window includes a 1.1 frame. windows and double-glazed window 1.2, which performs the function of a window sash (Fig. 1). Double-glazed window 1.2. enclosed in a frame consisting of internal and external parts 2 and 3 interconnected by fastening elements, respectively. The edges of the window frame 1.1 and the edges of the frames 2 and 3 are located at the level of the free edge of the spacer frames 4 (in the area of the glass connection unit of the double-glazed unit 1.2), without exceeding this level, which increases the light transmission of the window (Fig. 3).

Rotary hinges 5 are built into the lower inner part 2 of the double-glazed window frame, coaxial with the fixed hinges 6 attached to the lower part of the window frame 1.1. The named loops 5 and 6 are connected through axis 7.

The mechanism for controlling the position of the flap consists of a control handle 6 connected to a shut-off valve consisting of a tetrahedral pin 10 located in the cavity of the handle 6, the free end of which is connected to a rocker arm 11, on which a pin 12 is attached, connected to a rod 13 in the form of a plate, configured to move in the vertical direction inside part 2 of the flap frame (Fig. 3). The rod 13 is configured to interact with the plate 14 thanks to an inclined protrusion 8.1 located in the upper part of the rod 13, which is configured to move along a corresponding inclined groove 8.2 formed on the edge of the plate 14, which is made to move in the horizontal direction (Fig. .2). The movement of the rod 13 through the said angular connection with the plate 14 causes the latter to move with the retainer 15 attached to it. The latter engages with the protrusion 21, made in the corresponding place of the window frame 1.1 (Fig. 3). The plates 13 and 14, made of metal, simultaneously with the locking function serve the function of strengthening the inner part of the frame 2 of the flap.

The window has three operating positions: closed (Fig. 4a); slot ventilation (Fig. 4b) and the maximum tilting provided (Fig. 4c), providing “bulk” ventilation of the room and guaranteed safe window cleaning.

Limitation of the degree of tilting of the window sash during slot ventilation (rotation of the control knob 9 by 90º) is carried out by means of a locking element 16, having an L-shaped profile, fixed to the rod 13 (Fig. 2, 3, 5). The locking element 16 is designed to rest when tilting the sash against the stop-limiter 17, which also has an L-shaped profile and is fixed to the window frame 1.1.

With the maximum permissible tilting of the glass unit 1.2, corresponding to the maximum upward movement of the rod 13 (rotate the control knob 9 upward by 180º), the locking element 16 attached to it leaves the contact zone with the stop-limiter 17 (see Fig. 2, the upper designation of the locking element 16 dotted line), and tilting occurs to a position limited by two slats 18. Both slats 18 are hingedly connected to each other, with the end of one bar fixed to the window frame 1.1, and the end of the other bar to the frame of the double-glazed window 1.2 (Fig. 1).

The window sash is closed by turning the control handle 9 180º down, while the rod 13 moves downwards as much as possible (see Fig. 2, the lower designation of the locking element 16 is dotted).

The window frame 1.1 is reinforced with reinforcing steel profiles 19, connected in the corner sections of the frame by fastening plates 20 (Figs. 3, 6), thereby forming a rigid closed structure to which the weight of the glass unit 1.2 is transferred through the hinges 6, while the outer polymer parts of the window frame 1.1 are unloaded, which makes it possible to reduce the cross-sectional dimensions of the polymer profile and reduce its cost.

In the profiles 19, cavities are formed (Fig. 3, 5), intended for thermal insulation of the room from air coming from outside.
