Description

The invention relates to a sealing device for a moving leaf, made as a sliding or lifting-sliding leaf of a window or door.

Various designs of moving sashes in the form of sliding or lifting-sliding sashes of windows or doors are already known, they consist of at least a sash for closing and opening, made as a sliding sash and located with the possibility of movement on an external composite box, as well as an additional one located on a composite box of a door or window unit, such as a fixed panel.

A closed sliding sash can be locked on a composite box from a side remote from the window or door block by means of fittings provided on the frame, which provides protection against unauthorized opening. The fastenings of the sliding flaps are usually located under or above the sliding flap, making it possible to move it. When opening the sliding-sliding sash, which is usually produced using the handle, the sliding sash rises with the gaskets, which makes it easier to move. In this case, the open sliding sash can be moved relative to the stationary part located nearby. Depending on the version, the lifting and sliding flaps can only move or have an additional tipping function. When closing, the sliding sash is lowered, as a result of which the gaskets are pressed again. Opening and closing can also be carried out using electric, hydraulic or pneumatic actuators.

The weak point from the point of view of unauthorized opening is the butt area, in which a closed leaf is connected to an additional door or window unit. In this area of the joint, an attempt can be made to squeeze the closed sliding sash from the additional door or window unit in the direction perpendicular to the plane of the window or door using a special tool that will allow you to open the door or window by force.

This is avoided by the already known fixing devices for the joint zone, made in the form of safety strips or profiles of the same shape.

They are made of metal and have one first profile segment, each of which is integral with the second profile segment and is located at a distance from this second profile segment. The safety profiles are fixed on the corresponding vertical segment of the sash frame and the additional door or window unit so that when the sliding sash is closed, the safety profiles overlap in the area of the location of their first profile segments and at the same time provide such undercutting that the safety profiles effectively counteract attempts to force open the closed a sliding sash and an adjoining additional door or window unit.

A disadvantage of the known safety profiles is their poor heat and sound insulation, which is why it is necessary to use additional gaskets on the safety profiles to ensure sufficient heat and sound insulation, along with those that are located directly between the safety profiles when the sliding sash is closed. These additional seals interact with an additional door or window unit and are subject to increased wear as a result of movement of the sliding sash when opening and closing.

This problem is known, and appropriate sealing devices are available on the market.

A known device is described in the application DE 20119725 U1. To fix the door and / or window leaf of the door and / or window of the building in the junction area with the adjacent additional door or window block, a device is formed consisting of at least two safety profiles, one of which in the joint zone is attached by the fastening side to the sash frame , and the other is attached by the mounting side to an additional door or window unit. The profile segments of the safety profiles form, when the sash is closed, mutual undercutting or overlapping emphasis. For these purposes, the safety profiles are made in the form of a two-component part, consisting of a first profile component that forms at least one profile segment, as well as a second, made of heat and / or sound insulating material, profile component, which is at least partially , covers the first profile component on the side remote from the mounting side.

The locking mechanism in the known device requires a large mounting space to accommodate elements of a two-component structure; this may adversely affect the functionality of the device with regard to protection against unauthorized opening and heat and sound insulation.

Due to the safety profile of the safety profile visually accessible from the outside of the window or door between the first profile component and the second coated profile component, it becomes possible to loosen the locking mechanism by simple means, and when removing the coated profile component, fixing bolts are provided for fastening the second profile component to the window or doors are released and made available, making the window or door easy to open.

Both heat and sound insulation are also insufficient, since only the coated profile component is made of heat and sound insulating material. No attention is paid to the gaps between the sliding sash and the fixed panel. The device has not taken sealing measures to protect it from possible penetration of water as a result of high wind and rain loads, which may adversely affect the entire design of the window or door.

From the application DE 2839740 A1, a sliding, pivoting-sliding window or a sliding, pivoting-sliding door with a composite frame, a sliding sash, a fixed sash and fixed to the upper horizontal crossbar of the composite box, provided with sealing gaskets, an intermediate seal between the composite box and the upper horizontal crossbars is known sash frames in the overlapping zone of the sashes in the closing position.

The basis of the invention is the task of presenting a functional and compact sealing device for a movable sash, made as a sliding sash or a movable sliding-sliding sash of a window or door, in which the listed disadvantages will be eliminated, that is, the characteristics of heat and sound insulation, rainfall resistance will be improved, maintaining protection against unauthorized access, with good appearance and cost-effective, which will provide simple, quick and reliable installation and adjustment of and small installation space.

To solve this problem, a sliding or lifting-sliding sash of a window or door contains a sealing device consisting of two sealing rails, which are located in the joint zone between the sliding sash and the fixed panel for sealing and protecting the intermediate cavities when the sliding sash of the window or door is closed. At the same time, in the joint zone on the frame of the sliding sash, the sealing rail is fixed with the adjacent surface of the sash frame, and on the frame of the additional fixed panel, the sealing rail is fixed with the adjacent surface of the frame of the fixed panel, the sealing rails consisting of one profile component containing the first profile segments which, when closed the sash form a mutual undercut or an overlapping stop, and with the seals opposite, they form a kinematic connection. The profile components are preferably located on the side parallel to the adjacent surface of the sash frame or from the adjacent surface of the frame of the fixed panel, accommodating a groove in which the mounting bolts are mounted flush to the side. Thus, the mounting bolts are invisible and protected from unauthorized access from the outside of the window or door.

Thanks to the enclosing groove located along the entire length of the sealing rails, the fixing bolts are installed without additional mounting tools, and the sealing rails are screwed. Incorrect fastening of the sealing rails is thus excluded.

For the sake of simplicity and in order to reduce cost, standard fixing bolts are used. Additional protection against unauthorized access while providing a heat and sound insulating effect is achieved due to the fact that the enclosing groove, by means of a geometric or power closure, accommodates a casing strip that hermetically covers the enclosing groove almost flush with the side parallel to the adjacent surface of the sash frame or from the adjacent the surface of the frame of the fixed panel. Covering the mounting bolts, the casing provides additional protection against unauthorized penetration and, thanks to its location flush with the surface of the profile component, prevents penetration with the tool, due to which the sealing rails are only subjected to compression, which increases the stability of the entire sealing device and makes penetration even more difficult.

Simple installation and reliable fastening of the casing strip is provided by simple and inexpensive means in the preferred way due to the fact that the casing strip is latched into the enclosing groove by means of a locking mechanism. To this end, on the adjacent adjacent surfaces of the casing strip, there are corresponding convex coextruded sealing beads directed towards the enclosing groove, which engage with the snap concave grooves of the groove. Sealing collars additionally increase the tightness and protect against possible water penetration as a result of wind and storm loads, compensate for tolerances in the connection of the profile component and the casing and, thanks to the compressibility, maintain the joint.

In order to ensure the listed advantages, the sealing beads are made of soft PVC or rubber material, for example, rubber.

In order to avoid negative impact on the appearance of a window or door and to provide a simple and inexpensive design, the profile component is preferably made of a polymeric material and contain corresponding transverse cross-sections in almost the same material thickness in the cross section, which form hollow chambers using the forming function of the profile component. In order to increase the stability of the connection between the sealing rails, the sliding sash and the fixed panel, the fixing bolts are located in at least two pre-drilled guide cross webs.

Improving the functionality of the sealing device by improving the heat and sound insulation is ensured by the fact that the casing has a T-shaped recess on one free front side for accommodating by means of a geometric closure of the brush seal, which in turn seals the gap between the sealing rails and the corresponding adjacent surfaces sliding sash and fixed panel, while being in movable contact with adjacent surfaces. The choice of a brush seal allows, along with the achievement of high insulation performance, to provide good sliding properties for moving the sliding sash to a fixed panel.

An advantage is also that the sealing device, if necessary, can be installed in a window or door without a brush seal. To avoid possible contamination of the T-shaped recess for the brush seal, the casing has a predominantly symmetrical design, which allows a smooth side opposite the T-shaped recess to be flush against the side of the profile component by simply turning around its own axis.

Sealed protection against possible penetration of water as a result of high wind and storm loads is additionally provided due to the fact that the profile component has a groove on the side facing the adjacent surface of the sash frame, and the middle axis of the mounting bolt forms the middle of the groove and the accommodating groove . Due to the location of the gasket on the middle axis of the fastening bolt, the force closure of the fastening bolts ensures an optimal tight closure between the sealing rail and the connection with the sliding sash and the fixed panel.

The function, installation and cost of fittings are also positively affected by the fact that the sealing device can be mounted independently of the handle hardware and regardless of the manufacture of a window or door. Both horizontal and vertical installation of the sealing device in the gap between the sliding sash and the fixed panel or composite box is possible.

Presented in FIG. 1, the window or door consists mainly of an external composite box 2, in which for opening and closing the door 1 a movable leaf is provided in the form of a sliding leaf 3, as well as a fixed panel 4.

The sash 3, made, for example, in the form of a sliding-sliding sash, contains, among other things, the sash frame 5 and the glazed surface 6 provided in this frame. The fixed panel 4 consists mainly of the frame 7 and the corresponding glazed surface 8.

With the sliding sash 3 closed according to FIG. 1 the sash by means of constipation of the composite box 2, with the help of the incoming locking elements provided on the sash frame 5, not shown in the drawing, the fittings are fixed at least on the vertical side of the sash 5 frame remote from the fixed panel 4 on the composite box 3. Problematic, however, there is a transition or butt zone 9 between the closed sliding sash 3 and the fixed panel 4, where the sash frame 5 and the frame of the fixed panel 7 overlap with the vertical segments of the frame 5 'and 7', forming a transition, and the vertical the sash frame segment 5 '5 and the vertical frame segment 7' of the fixed panel 7, when looking at the plane of the sliding door 1, are located one after another, and the surfaces 5 '' and 7 '' are located next door. In this joint zone 9, when the door 3 is closed, a gap 9 'inevitably remains between the segments 5' and 7 ', which is also accessible from the outside of the window or door 1, and through which there is theoretically the possibility of force opening using a special tool for breaking through sliding flap 3 and fixed panel 4. The same gap occurs according to FIG. 3 in the upper horizontal region of the sliding sash 3 and the fixed panel 4 or the composite box 2; this gap must be secured and sealed. For this, the sliding leaf 3 or the sliding-sliding leaf of the window or door 1 comprises a sealing device 10 according to FIG. 1-3, which consists of vertically and horizontally mounted sealing rails 11, 12 located in the butt zone 9 between the sliding sash 3 and the fixed panel 4 for sealing and protecting the intermediate cavities 9 'of the closed sliding sash 3 of the window or door 1. in the area of the joint 9, the sealing rail 11 is fixed by the adjacent surface 5 ″ of the sash frame on the frame 5 of the sliding sash 3, and the sealing rail 12 is fixed by the adjacent surface 7 ″ of the frame of the fixed panel 7 on the frame of the fixed surface 7 of additional Vision panel 4 consisting of a profile wherein the part 13 sealing slats 11, 12 comprise first profiled segments 14 which, when closed sliding leaf 3 form a mutual abutment undercut or overlap, and arranged with opposite seals 15, they form a kinematic linkage.

Profile components 13 in accordance with FIG. 1-3, this is most clearly seen in FIG. 3 preferably comprise on the side 16 parallel to the frame of the sash frame parallel to the adjacent surface 5 ″ or the adjacent frame surface 7 ″ of the frame of the fixed panel, accommodating a groove 17 in which the mounting bolts 18 are mounted flush from side 16. Thus, the fixing bolts 18 are invisible, in accordance with FIG. 2 and 3, and protected from unauthorized access from the outside of the window or door 1. Due to the accommodating groove 17 located along the entire length of the sealing rails 11, 12, the fixing bolts 18 are installed without additional mounting tools, and the sealing rails 11, 12 are screwed at a predetermined distance from friend. Incorrect fastening of the sealing rails 11, 12 is thus excluded. The enclosing groove 17, by means of a geometric or force closure, accommodates, according to FIG. 2-4, a casing strip 19, which hermetically covers the enclosing groove 17 is practically flush with the side 16 parallel to the flush frame adjacent to the adjacent surface 5 '' or from the fixed panel frame adjacent surface 7 ''. Covering the fixing bolts 18, the casing strip 19 provides additional protection against unauthorized entry and, thanks to its alignment with the surface of the profile component 13, prevents penetration by means of a tool, due to which the sealing rails 11, 12 are only subjected to compression.

According to FIG. 4, the casing strip 19 is latched into the enclosing groove 19 by means of a locking mechanism 20. For this purpose, convex coextruded sealing collars 22, which snap into the corresponding concave recesses 23 of the enclosing groove, are directed towards the enclosing groove 17 on the lateral adjacent surfaces 21 of the cladding 19. 17. Sealing collars 22 additionally increase the tightness and protect against possible water penetration as a result of wind and storm loads, compensate the tolerances in the joint and profile obshivnoy component 13 and plank 19, and due to the property of compressibility, the junction profiled support component 13 is made preferably of polymeric material and comprises, for example, according to FIG. 2, in cross section with practically the same thickness of the material, corresponding transverse bridges, which form hollow chambers using the forming function of the profile component 13. In order to increase the stability of the connection between the sealing rails 11, 12, the sliding leaf 3 and the fixed panel 4, the fixing bolts 18, as can be seen from FIG. 2, are located in at least two pre-drilled guide cross webs

According to FIG. 2-4, the sealing device 10 comprises, on the casing strip on one free face 24, a T-shaped recess 25 for receiving by means of a geometric closure of the brush seal 26, which in turn seals the gap 27 between the sealing rails 11, 12 and the corresponding adjacent surfaces 5 ' ', 7' 'of the sliding sash 3 and the fixed panel 4, while being in movable contact with the adjacent surfaces 5' ', 7' '. The choice of the brush seal 26 allows the thorn between the sliding leaf 3 and the fixed panel 4 to be almost completely avoided during the movement of the sliding leaf 3. Thus, working noise can also be avoided.

As follows from FIG. 3, the sealing device 10, if necessary, can be installed in the window or door 1 without the brush seal 26. The symmetrical design of the skin strip 19 allows using a simple pivoting movement to use the side opposite the front side 24, which is flush against the side of the profile component 13.

In addition, the profile component 13 has, according to FIG. 2, on the side facing the adjacent surface 5 ″ of the sash frame and the adjacent surface 1 ″ of the frame of the fixed panel, groove 28 for receiving the gasket 29, the middle axis of the fixing bolt 18 forming the middle of the groove 27 and the accommodating groove 17. Due to the location of the sealing gaskets 29 on the middle axis of the fixing bolt 18, the power closure of the fixing bolts 18 provides optimal tight closure between the sealing rail 11, 12 and the connection with the sliding leaf 3 and the fixed panel 4.

The function, installation and cost of the fittings are also positively affected by the fact that the sealing device 10 can be mounted independently of the fittings of the handle and regardless of the manufacture of the window or door 1. Installation can be carried out as described above in FIG. 1 along section AA in the vertical zone of the joint 9 according to FIG. 2 or in FIG. 1 with a cross-section BB in the horizontal upper zone of the joint 9 in accordance with FIG. 3, preferably without a brush seal 26. The design allows installation and replacement of the sealing device after the manufacture of a window or door 1 to be carried out without problems.
