Description

The invention relates to a sealing device for a sliding wing as sliding sash or sliding lift-sliding sash of a window or a door according to the preamble of claim 1.

Sliding wings as sliding sash or sliding lift-sliding sash of a window or door are known in various designs and consist in the simplest case of a slidably arranged in an outer frame for opening and closing wings arranged as sliding sash and from a, also arranged in the frame further door. or window element, for example fixed field.

The closed sliding sash can be locked on its side facing away from the other door or window element by pressing a fitting provided in the sash frame on the frame and thus secured against unauthorized opening. Sliding sashes are usually slidably received above or below the sliding sash. When opening, usually with an operating handle, lift-and-slide panels raise the sliding sash with the seals, making it easier to run. The opened sliding sash can then be pushed in front of an adjacent fixed part. Depending on the version, lift-slide sashes can only be pushed or tilted additionally. When closing the sliding sash is lowered and thus the seals pressed again. The opening and closing is also possible via electrical, hydraulic or pneumatic actuators.

But a weak point against unauthorized opening forms the joint area at which the closed sliding sash connects to the other door or window element. In this joint area, an appropriate tool may be used to force the closed sliding sash and the other door or window element apart perpendicular to the door or window level so as to force open the door or window.

To prevent this, already securing devices for the impact area are known, and although in the form of two equally shaped securing rails or profiles. These are made of metal and each have a first profile section, which is manufactured in one piece with a second profile section and projects from this second profile section. The security profiles are then each attached to a vertical portion of the sash and the other door or window element that overlap with closed sash the security profiles in the region of their first profile sections and at the same time engage behind such that the backup profiles an attempt is effectively counteracted, to press apart the closed sliding sash and the subsequent further door or window element for forcible opening.

A disadvantage of the known safety profiles is their poor thermal and acoustic insulation, so that in order to achieve a sufficient heat and sound insulation in addition to seals that act directly closed between the safety profiles with closed sliding sash, more seals are used on the safety profiles, with the wing or interact with the other door or window element and subject to increased wear by the movement of the sliding leaf when opening and closing.

This problem is known and there are corresponding sealing devices on the market.

A known device is in the DE 20119725 U1 described. To secure a closed door and / or window sash of a building door and / or a building window in a joint area to a subsequent door or window element, the device consisting of at least two security profiles of those in the joint area a profile with a mounting side on the frame of the wing and a profile with a mounting side on the other door or window element can be fastened. Profile sections of the security profiles form a mutual over- or behind reaching behind the wing closed. For this purpose, the securing profiles are each formed in two parts, consisting of a first profile body, which forms the at least one first profile section, as well as a second, made of a heat and / or sound insulating material profile body of the first profile body on a side facing away from the fastening side at least partially covering.

The known device requires a lot of space for the implementation of a security device by the two-part arrangement of the components, which can lead to an impairment of the functionality in terms of protection against unauthorized opening and the thermal and acoustic insulation of the device.

By the visible from the outside of the window or the door locking device the securing profile between the first profile body and the second covering profile body offers the possibility to solve the locking device with simple means, being released and accessible with removal of the covering profile body, arranged for attachment of the second profile body to the window or the door mounting screws and the window or door is easy to open.

Also insufficient is the insulation for thermal and acoustic insulation, since only the covering profile body is made with heat and / or sound insulating material. Columns between sliding sash and fixed field are ignored. Measures for sealing against possible ingress of water by high wind loads and driving rain stress have not been taken in the device, which can lead to the consequence of impairments of the entire window or the door.

Is known from the DE 2839740 A1 a sliding, lifting sliding window or a sliding or sliding door with a frame, a sliding sash, a fixed wing and a fixed at the top, horizontal frame spar, equipped with sealing strip center seal between the frame and the upper horizontal wing frame spars in the overlapping region of the wings in the closed position ,

The invention has for its object to provide a functionally reliable and compact sealing device for a sliding wing as a sliding sash or sliding lift-slide sash of a window or door, which overcomes the above disadvantages, ie with respect to the thermal and acoustic insulation, the Improves road-tightness with retention of security against unauthorized intrusion and is cost effective with good optics for the window or the door and which can be mounted and adjusted in a simple, fast, safe and precise manner with little space.

To solve this problem, a generic sliding sash or lifting sliding sash of a window or a door on the features of the characterizing part of claim 1.

The mounting screws are thus not visible and inaccessible from a possible engagement of the outside of the window or the door arranged.

By, over the entire length of the sealing strips arranged receiving groove, the mounting screws can be positioned without further mounting aid and attach the sealing strips screwed. An incorrect attachment of the sealing strips is thus excluded.

For the sake of simplicity and cost-reducing standard fixing screws are used. Another security against unauthorized interference while heat and sound-insulated effect is achieved in that the receiving groove a cover strip positively and / or non-positively absorbs, which covers the receiving almost flush with the wing frame contact surface or Festfeldrahmenanalagefläche parallel side facing away sealing. The cover provides with the covering of the mounting screws further protection against unauthorized intrusion and allowed by the flush arrangement with the surface of the profile body no possibility of intervention of a tool, so that the sealing strips can only be loaded on pressure, resulting in a further stabilization of the entire sealing device and a Intrusion further difficult.

A simple installation and a secure hold of the cover strip are obtained by simple and inexpensive means advantageously characterized in that the cover strip can be clipped into the receiving groove by means of a locking device. For this purpose, convexly anextruded sealing beads are arranged on the respective contact surface for receiving, on the lateral contact surfaces of the cover, which engage complementary in correspondingly concave recesses of the receiving groove. The Dichtwulste also offer a high density against the possible ingress of water through wind loads and driving rain, equal tolerances between the connection of the profile body and the cover and act supportive by a pressing behavior on the seat of the compound.

To realize the above advantages, the sealing beads are made of a soft PVC or a rubber material such as rubber.

In order not to adversely affect the existing appearance of the window or door and to achieve a simple and cost-effective production, the profile body is made of a plastic material and has in cross section at almost the same thickness of material corresponding webs which form by the profile body forming hollow chambers.

Preferably, to increase the stability of the connection between the sealing strips and the sliding sash and the fixed field, the fastening screws are guided by at least two pre-drilled webs leading.

A functional extension of the sealing device with respect to increase the heat and sound insulation is effective, that the cover strip on a free viewing side a T-shaped recess for positively receiving a brush seal, which in turn sealingly closes a gap between the sealing strips and the respective contact surfaces of the sliding leaf and fixed field and is in movable contact with the contact surfaces. With the selection of the brush seal good sliding properties are achieved when moving the sliding sash to the fixed field by achieving high insulation values.

It has proved to be particularly advantageous that the sealing device can also be used without brush seal in the window or door as required. To avoid possible contamination in the T-shaped recess for the brush seal, the cover is advantageously symmetrically constructed so that the use of the opposite to the T-shaped recess flat side is possible by simple rotation about its own axis, which flush with the side of the profile body comes to rest.

A high tightness against a possible ingress of water by wind loads and driving rain stress is additionally supported by the fact that the profile body has a groove for receiving a sealing strip on the wing frame contact surface and Festfeldrahmenanalagefläche side, wherein the central axis of the fastening screw forms the center of the groove and the receiving groove , Due to the arrangement of the sealing strip almost on the central axis of the fastening screw, an optimal sealing between the sealing strip and the connection to the sliding leaf and the fixed field is generated by the force of the screw fastening screws.

In addition, it has proven to be advantageous to the function, installation and cost of the fitting that the sealing device is independent of the fitting of the actuating linkage and independent of the production of the window or door mountable. An assembly of the sealing device is possible both horizontally and vertically between the sliding leaf and the fixed field or frame forming gap.

The designated in the figures 1 window or door consists essentially of an outer floor or window frame 2, in which a sliding to open and close the door 1 wings are provided as sliding sash 3 and a fixed field 4.

The wing 3, which is designed for example as a lift-slide wing, has u.a. the sash 5 and provided in this context glazing 6. The fixed field 4 consists essentially of the frame 7 and the associated glazing 8.

With the sliding sash 3 closed Fig. 1 , This is intervening by locking the frame 2 locking elements provided on the sash 5 - not shown fitting - locked at least on the fixed field 4 remote vertical side of the sash 5 on the frame 3. The problem, however, is the transition or impact area 9 between the closed sliding leaf 3 and the fixed field 4, at which a transition forming the sash 5 and the fixed field frame 7 with vertical frame sections 5 'and 7' overlap, with a vertical portion 5 'of the sash and a vertical portion 7 'of the fixed field frame 7 are arranged one behind the other in the direction of looking at the plane of the sliding door 1 and are adjacent to one another with surfaces 5 "and 7". In this joint area 9 remains with the door closed 3 inevitably a gap 9 'between the sections 5' and 7 ', which is also accessible from the outside of the window or the door 1 and to which by means of a burglary tool a violent opening by pushing apart of the sash 3 and the fixed field 4 would be possible. Such a gap also arises after Fig. 3 in the upper horizontal region of the sliding leaf 3 to the fixed field 4 or frame 2, which is to be secured and sealed.

To avoid this, a sliding sash 3 or lifting-sliding sash of a window or a door 1 detects a sealing device 10 FIGS. 1 to 3 on, which consists of vertically and horizontally arranged sealing strips 11, 12, which are arranged in a joint area 9 between a sliding leaf 3 and a fixed field 4 for sealing and securing the interstices 9 'of a closed sliding leaf 3 of the window or a door 1. It is in the joint area 9, a sealing strip 11 with a sash bearing surface 5 "on the sash 5 of the sash 3 and a sealing strip 12 with a Festfeldrahmenanalagefläche 7" attached to the fixed field frame 7 of the other fixed field 4, wherein the existing of a profile body 13 sealing strips 11, 12 first Profile sections 14, which mutually overlap or engage behind with a closed sliding panel 3 and with oppositely arranged seals 15 form an operatively connected system.

The profile body 13 point after FIGS. 1 to 3 - In particular, clearly shown from the Fig. 3 , on the wing frame contact surface 5 "or Festfeldrahmenanalagefläche 7" side facing away from parallel 16 a receiving groove 17, are inserted into which mounting screws 18 inserted and sunk in the mounted state of the side 16. The fastening screws 18 are after Figures 2 and 3 thus not visible and inaccessible from a possible unauthorized engagement of the outside of the window or the door 1 arranged. By arranged over the entire length of the sealing strips 11, 12 receiving groove 17, the fastening screws 18 can be positioned without further installation aid and attach the sealing strips 11, 12 screwed at a predetermined distance. An incorrect attachment of the sealing strips 11, 12 is thus excluded. The receiving groove 17 decreases FIGS. 2 to 4 a cover strip 19 positively and / or non-positively, which covers the receiving groove 17 almost flush with the wing frame contact surface 5 "or Festfeldrahmenanalagefläche 7" parallel side 16 sealed. The cover strip 19 provides with the covering of the mounting screws 18 further protection against unauthorized intrusion and allowed by the flush arrangement with the surface of the profile body 13 no possibility of intervention of a tool, so that the sealing strips 11, 12 can be charged only on pressure.

To Fig. 4 the cover strip 19 can be clipped into the receiving groove 17 by means of a latching device 20. For this purpose, 19 convexly anextrudierte sealing beads 22 are arranged on the respective, the receiving groove 17 facing lateral contact surfaces 21 of the cover, which engage complementary in accordance with concave recesses 23 of the receiving groove 17. The sealing beads 22 also offer a high density against possible penetration of water by wind loads and driving rain, same tolerances between the connection of the profile body 13 and the cover strip 19 and act to support by a pressing behavior on the seat of the compound.

The profile body 13 made of a plastic material, for example, after Fig. 2 in cross-section at almost the same thickness of material corresponding webs, which form by forming the profile body 13 hollow chambers. To increase the stability of the connection between the sealing strips 11, 12 and the sliding leaf 3 and the fixed field 4, the fastening screws 18, as also shown in Fig. 2 emerges, led by at least two pre-drilled webs leader.

To Figures 2 and 4 the sealing device 10 on the cover strip 19 on a free visible side 24 a T-shaped recess 25 for the positive reception of a brush seal 26, which in turn a gap 27 between the sealing strips 11, 12 and the respective contact surfaces 5 ", 7" of the sash 3 and fixed field 4 sealingly closes and is in movable contact with the contact surfaces 5 ", 7". When moving or operating the sliding leaf 3 is formed by the choice of the brush seal 26 no significant friction between the sliding sash 3 and the fixed field 4th running noise are thus also avoided.
Like from the Fig. 3 As can be seen, the sealing device 10 can also be used without brush seal 26 in the window or door 1 as required. The symmetrical structure of the cover strip 19 allows by means of rotational movement, the use of the opposite side of the visible side 24, which comes flush with the side 16 of the profile body 13 to rest.

In addition, the profile body 13 on the wing frame contact surface 5 "and Festfeldrahmenanalagefläche 7" side facing Fig. 2 a groove 28 for receiving a sealing strip 29, wherein the central axis of the fastening screw 18 forms the center of the groove 27 and the receiving groove 17. Due to the arrangement of the sealing strip 29 almost on the central axis of the fastening screw 18, an optimal sealing fit between the sealing strip 11, 12 and the connection to the sliding sash 3 and fixed field 4 is generated by the force weft of the fastening screws 18.

Furthermore, it has proven to be advantageous to the function, installation and cost of the fitting that the sealing device 10 regardless of the fitting of the actuating linkage and regardless of the manufacture of the window or the door 1, both as described above in Fig. 1 after section AA in the vertical joint area 9 after Fig. 2 , or after Fig. 1 with section BB in the horizontal upper joint area 9 after Fig. 3 , preferably can be mounted without brush seal 26. An assembly or replacement of the sealing device 10 after the production of the window or the door 1, due to the design easily possible.
