Abstract

This invention is intended for construction and describes the structure of adjustable windows, which may be quickly installed into any type of niche. The invention may be applied to temporary building insulation during cold periods, using such windows as additional sealing windows and for quick closure of any open niche. The type of window described in the invention differs by its frame, which is made of two parts - the main part, tightly assembled part and the sliding adjustable one, consisting of a stand and crossbar which are joined together with tenons and channels and to the main part of the frame, therefore the window outside dimensions may be changed in the range of 10 cm. Between the main window part and the sliding adjustable part, some expanding fastening elements are installed (rubber inserts, springs, chocks, etc.). Thanks to these elements, the window installed in a sealing niche is enlarged and tightly pressed to a niche or another sealing window inside a frame. Air-tightness is guaranteed, because the adjustable window is sealed by the sealing tape around the entire perimeter.

Description

The invention relates to a construction and describes the construction of an adjustable window that can be quickly inserted into any closed niche and the method of attaching it to that niche.

The invention can be applied to the temporary insulation of buildings in the cold period using a window such as an auxiliary sealing window and the rapid closure of any open niche.

GB 2251261 describes a method for fastening a window unit in a recess by means of adjusting wedges. In this way, the window can be installed relatively quickly, but in any case, there remains a gap between the outside of the window unit and the inner frame of the niche, which must then be further sealed.

FR 2640311 discloses a laminated window frame consisting of at least two parts: a cross member and a stand. The transverse has a stitch and the stand has a groove. However, it is not mentioned in the present invention that the window stand could slide in any way along the transverse joint and vice versa.

The closest technical solution is the window unit described in the LT 4060 B patent, consisting of a rigid frame encased in a transparent polymer film for additional sealing of existing windows in buildings. The disadvantage of this window unit is that its exterior dimensions must be precisely matched to the internal dimensions of the window frame to be sealed beforehand. In addition, it is intended to be used only as an additional internal window.

The present invention discloses a construction and method of mounting an adjustable window whose external dimensions can be quickly adapted to the internal dimensions of any niche.

The window according to the invention is characterized in that its frame consists of two parts - the main, rigidly assembled part, covered with any transparent polymer film, and a sliding adjustable part, consisting of a rack and a transverse, which are connected with each other and with the main part of the frame. There is also a stretch film between the main part and the adjustable part. With its slots, the stand can slide freely along the transverse studs, and vice versa, allowing the outside dimensions of the window to vary by ± 5 cm.

There are several expanding fasteners (rubber inserts, springs, wedges, etc.) between the main part of the window and the sliding adjustable part. Thanks to these elements, the window in the sealed niche is expanded and firmly pressed against the inside of the niche. The adjustable window is surrounded by a sealing strip all around the perimeter to ensure tightness. The niche that is inserted in this way holds the window fairly firmly. It can withstand a force of up to 10 kg / m ² acting in the steep direction of the window surface.

The invention will now be described in more detail with reference to the drawings in which:

Fig. 1 is a front view of an adjustable window;

Figure 2 is an axonometric view of window unit A;

Figure 3 is an axonometric view of window unit B; and

Figure 4 is an axonometric view of window unit C.

As shown in Fig. 1, the adjustable window 1 consists of a main part consisting of four rigidly fixed frame members 2, 3, 4, and 5, and an adjustable part consisting of a horizontally sliding arrow 6 in the direction of rack 7 and a vertically sliding arrow 8 in the transverse 9 The main body has studs 10 which can be slid along a transverse 9 having corresponding grooves at its ends and ends 11 with grooves that can be slidable by a stand 7 having corresponding studs at its ends. These elements and their interactions will be described in more detail below with reference to Figures 2 and 3.

Fig. 2 is an axonometric view of adjustable window node A. As can be seen, a portion 12 of the window element 2 of the frame 1 is provided with a notch 12 which acts, in this case, as a guide, in which the spines of the stand 7 can slide in the direction of arrow 6 (fig.

13. Accordingly, the lower part 7 of the rack 7 is provided and shown in Fig. 3, the stud 14 of which can slide simultaneously in the groove 12 of the window member 4 of the element 4 and the groove 15 of the left end 15 of the transverse 9. significantly longer as it slides up and down the transverse 9 of the adjustable portion of window 1.

Fig. 4 is an axonometric view of the adjustable window node C. This assembly also consists of two elements - window frame 1 element 3 spigot 10 and transverse 9 with a groove 16. As can be seen, transverse 9 can slide upwardly of window 1 frame element 3 spigot 10. Accordingly, the left end of the transverse end is disposed. in that the notch 15 can slide right along the two studs -10 and 14.

In this way, the entire construction of the adjustable window 1 is characterized in that the outside dimensions of the window 1 can be altered by respectively moving the window stand 7 or transverse 9 or both at once.

Several expanding fasteners 17, such as wedges, springs, rubber inserts and the like, are inserted between the frame members 4, 5 of the window and between the transom 9 and the rack 7. The purpose of these elements is to expand the window as much as possible and squeeze it as nicely as possible. Fig. 1 shows four such expanding fasteners 17, however, their number may be different and depends on the dimensions of the window. The larger the window, the more these elements are needed.

Maximally expanded window, i.e. as it is at rest, it is pre-coated with any transparent, weather-resistant film 18, such as polyethylene film, by attaching, gluing or otherwise sealing it to the frame members 2, 3, 4 and 5 of the main body of window 1; and at rack 7 and transom 9. Such a window is ready to be built into a recessed niche. Prior to the construction of the window 1, the expanding fasteners 17 are removable and the outside dimensions of the window are adjusted to the internal dimensions of the closed niche, i.e. The rack 7 and transverse 9 are displaced such that the outer dimensions of the window 1 are slightly smaller than the inside dimensions of the covered recess. If necessary, the projections 3, 5 of the frame members 10, the ends 11 of the frame elements 2, 4 and the left ends of the studs 14 and the bar 9 of the rack 7 are cut out. The window 1 is then wrapped around the perimeter with a self-adhesive sealing strip and inserted into the recess. The expanding fasteners 17 are reinserted. Under the influence of the pushing forces of these elements, the rack and transverse 9 move outwards and the window 1 is pressed against the inside of the niche frame all the way around. Since window 1 is surrounded by a sealing strip, the closed niche is sealed.

When the window is thus installed, the transparent film 18 between the frame members 4, 5 of the window 1 and the adjustable portion of the stand 7 and the transom 9 may relax slightly. However, the tightness of window 1 is not affected.

The gap between the frame members 4, 5 of the window 1 and the adjustable portion of the rack 7 and the transom 9 may be individually covered by a film 18 once the window 1 has been inserted into the closure recess. The entire film covering the window 1 will then be evenly tensioned.

It is also possible that the main part of the window 1 consisting of the frame elements 2, 3, 4, 5 is pre-glazed and the gap between the frame elements 4, 5 of the window 1 and the adjustable part rack 7 and transverse 9 is covered with transparent film.

In this way, window 1 can be inserted very quickly and easily into any closed niche or can be used as an additional second or third sealing window during the cold period. Since its dimensions can vary within 10 cm thanks to the additional sliding elements 7 and 9, there is no need to produce a window of exact dimensions. Due to the effect of the expanding fasteners 17 and the frictional force of the sealing strip around the frame of the window 1, the window is very firmly held in the open recess.

The present invention describes a window having a frame made of wood. However, it is obvious to one skilled in the art that other materials may also be used to make the frame, such as plastic or light metal.
