Description

The invention relates to a sealing arrangement for an opening element such as windows or doors, which is movable for opening and closing a building opening in a sliding movement from an opening position in which the building opening is released into a closed position in which the opening element covers the building opening the preamble of claim 1.

Due to the increasing automation in building technology, there is a need for suitable solutions for opening and closing a building opening using opening elements such as windows or doors. In particular, the standard-compliant sound and / or heat-insulating sealing of such building openings is an essential factor. In addition, a slim design and flush installation are generally desired, in which technical components should not be visible if possible. In the DE 2319399 A1 and the ES 2557030 A1 a sealing strip with permanent magnets is described, which bring the sealing strip into a sealing system in a closed position of the opening element. The pamphlets EP 2995761 A1 and E 102004050326 B4 describe the use of electromagnets to achieve a sliding movement of windows or doors.

It is therefore the object of the invention to provide a sealing arrangement for an opening element such as windows or doors for opening and closing a building opening, which not only enables the opening element to be opened and closed automatically with standard contact pressure, but also an appealing design and a flush installation enables.

This goal is achieved by the features of claim 1. Claim 1 relates to a sealing arrangement for an opening element such as windows or doors, which is movable for opening and closing a building opening in a sliding movement from an opening position in which the building opening is released into a closed position in which the opening element covers the building opening . According to the invention, it is proposed that one with permanent magnets Provided sealing strip is provided, which is movably mounted on a stationary frame part in a direction perpendicular to the sliding direction of the sliding movement of the opening element, and the opening element has permanent magnets interacting with the permanent magnets of the sealing strip, with which the sealing strip in the closed position of the opening element in a tight system can be brought to the opening element, the stationary frame part being provided with at least one electromagnet, with which, when current flows, the sealing strip in the closed position of the opening element can be moved from the tight system into a position spaced from the opening element, and the opening element and the fixed frame part each have a receptacle for the sealing strip, which form a receiving channel for the sealing strip only in the closed position of the opening element, in which the sealing strip is perpendicular to the sliding direction of the sliding movement of the opening element nts is movable and positively guided.

The stationary frame part is arranged in the region of an edge of the building opening and can also be part of a frame which surrounds the building opening. With the aid of a sliding movement, the opening element can be moved from an open position, in which the opening element opens the building opening, into a closed position, in which the opening element covers the building opening. The opening element will generally be a window or a door, so that the sliding movement takes place in a plane defined by the window level or the door leaf, wherein the opening element can also be mounted displaceably on the stationary frame part. When the closed position is reached, the opening element is initially still at a slight distance from the sealing strip which is movably mounted on the stationary frame part in a direction perpendicular to the sliding movement, which is subsequently also referred to as an "opened seal". After reaching the closed position, however, the sealing strip is automatically brought into a dense system by means of the permanent magnets provided in the sealing strip and in the opening element Episode is also maintained. A power supply is not required for this, and the contact pressure can be ensured accordingly by selecting suitable permanent magnets. In this position the seal is "closed".

To open the seal electromagnets are provided according to the invention, which are arranged in the fixed frame part. With a corresponding current flow through the electromagnets, a restoring force is generated on the sealing strip via a magnetic interaction with the permanent magnets of the sealing strip, which overcomes the magnetic adhesive force between the sealing strip and the opening element and moves the sealing strip from the tight system into a position spaced from the opening element. All components of the sealing arrangement according to the invention can be arranged in frame parts of the opening element and the building opening, which are also covered by visible surfaces of the floor or window structure and thus cannot be visible. In particular, no fitting parts are required for the production of the contact pressure required for the seal, as a result of which visually appealing solutions can be implemented.

Since the opening element and the stationary frame part each have a receptacle for the sealing strip, which form a receiving channel for the sealing strip only in the closed position of the opening element, in which the sealing strip is movable and positively guided perpendicular to the sliding direction of the sliding movement of the opening element, structurally advantageous designs can be realized be realized. Outside the closed position, no such receiving channel is formed by the receptacles of the opening element and the stationary frame part, so that no movement of the sealing strip perpendicular to the sliding direction of the sliding movement of the opening element is possible. Instead, the sealing strip remains in the receptacle of the stationary frame part and does not impair the sliding movement of the opening element. The positive guidance of the sealing strip in the receptacles of the opening element and the frame part is achieved by the recordings of the opening element and frame part of the outer contour of the sealing strip follow in sections.

The sealing arrangement formed by the stationary frame part, the sealing strip and the opening element can be designed such that the sealing strip can only be moved from its position spaced apart from the opening element into its tight contact with the opening element when the opening position is reached. In this way, an impairment of the sliding movement of the opening element by the sealing strip before reaching the closed position is avoided. The permanent magnets provided in the sealing strip and in the opening element can be selected such that their magnetic attraction in the closed position of the opening element is sufficient to move the sealing strip from a position spaced apart from the opening element into a tight contact with the opening element. However, alternatively or additionally, it can be provided that, by reversing the current flow in the electromagnets, the sealing strip in the closed position of the opening element can be moved from a position spaced from the opening element into a tight system and / or the contact pressure of the sealing strip on the opening element can be changed. In this case, the magnetic interaction of the permanent magnets of the sealing strip and the opening element support the movement of the sealing strip from a position spaced apart from the opening element into its tight contact without initiating it, and in the tight contact of the sealing strip on the opening element, they provide a predetermined one by the choice of the permanent magnets Contact pressure safe, which can be varied by the magnetic interaction with the electromagnets of the frame part.

The sealing arrangement according to the invention can also be used not only for the movement of the sealing strip, but also for the movement of the opening element between its open and closed positions. For this purpose, it is proposed that the stationary frame part extend parallel to the sliding direction of the opening element and that a row-like arrangement of a plurality of electromagnets is provided along the stationary frame part, which is independent can be activated from each other by means of current flow, and by activating a first group of electromagnets the sealing strip can be moved, and by successively activating row-arranged electromagnets of a second group of electromagnets in interaction with the permanent magnets of the opening element, a feed force can be generated on the opening element to achieve the sliding movement of the opening element is. One possible embodiment provides, for example, that every second electromagnet belongs to the electromagnets arranged in a row in the first group, and the electromagnets in between in the second group. The activation of the first group moves the sealing strip from its tight contact into a position spaced from the opening element, in which it does not impair the sliding movement of the opening element. Subsequent activation of the electromagnets of the second group of electromagnets arranged in a row can subsequently generate a feed force on the opening element which opens or closes the opening element. By reversing the current flow through the first group of electromagnets, the sealing strip can in turn be brought into its tight contact with the opening element and / or the contact pressure can be varied.

A particularly compact design can be achieved by the sealing strip having plastic-bonded permanent magnets, and also receiving openings for receiving the electromagnets in the position spaced from the opening element. The sealing strip thus moves in the course of its movement from the tight contact to the opening element into its position spaced from the opening element via the electromagnets, so that the electromagnets are at least partially received by the receiving openings of the sealing strip.

Furthermore, it is proposed that the sealing arrangement be connected to a control device which performs the sliding movement of the opening element and the movement of the sealing strip between the tight system and the position spaced from the opening element in a sensor-controlled manner. By opening and closing the sensor controlled by sensors For example, automated ventilation is possible for the opening element, which can significantly reduce the ventilation energy and the overall energy requirement of the building. It can be operated using simple controls in the immediate vicinity of the corresponding building opening, or also remotely controlled using appropriate mobile phone applications ("apps").

First, the Fig. 1 Reference, which is a schematic view of an opening element 1 in its open position ( Fig. 1a ) in which a building opening is released and in its closed position ( Fig. 1b ), in which the opening element 1 covers the building opening. A sliding direction S of the sliding movement is in the Fig. 1a indicated by an arrow. The opening element 1 can be, for example, a sliding window or a sliding door, so that the sliding movement takes place in a plane defined by the window plane or the door leaf. Furthermore, a stationary frame 2 is visible, which surrounds the building opening. The opening element 1 can be slidably mounted on the stationary frame 2, or on its own suspension or guide.

On a stationary frame part 2a of the frame 2, a sealing strip 3 is movably mounted in a direction R perpendicular to the sliding direction S of the sliding movement of the opening element 1 (see also Fig. 2 ). This direction R is in the Fig. 1b indicated by an arrow. As a rule, all four side parts of the frame 2 will be provided with a sealing strip 3 designed according to the invention in order to ensure that the building opening is sealed on all sides. The sealing arrangement according to the invention is subsequently explained with reference to the lower side part of the frame 2 as a fixed frame part 2a.

For this purpose, the Fig. 2 and 3rd Reference is made to first explain the principle of operation of the sealing arrangement according to the invention, the Fig. 2a 2 shows a sectional view through an embodiment of the stationary frame part 2a, the sealing strip 3 and the opening element 1 with the seal closed, and FIG Fig. 2b with the seal open. The Fig. 3 shows an exploded view of the embodiment of the fixed frame part 2a, the sealing strip 3 and the opening element 1 according to Fig. 2 in perspective. From the stationary frame part 2a is in the Fig. 2 only an angular support can be seen on which electromagnets 4.i (i = 1, ... N) are arranged in a row. The electromagnets 4.i can be switched over electrical lines 5 and corresponding switches 6.i (i = 1, ... N) can be activated and deactivated separately.

The sealing strip 3 has plastic-bonded permanent magnets, and receiving openings 7.i (i = 1,... N) for receiving the electromagnets 4.i in the position spaced from the opening element 1 (see Fig. 2b ). The sealing strip 3 pushes itself in the course of its movement from the tight contact to the opening element 1 Fig. 2a in their position spaced from the opening element 1 according to Fig. 2b via the electromagnets 4.i, so that the electromagnets 4.i are at least partially received by the receiving openings 7.i of the sealing strip 3.

The opening element 1 also has a receptacle for the sealing strip 3 in the region of its lower edge, which follows the outer contour of the sealing strip 3 in sections. The opening element 1 also has, in the region of its lower edge, plastic-bound permanent magnets which, in interaction with the plastic-bound permanent magnets of the sealing strip 3, exert a magnetic force on the sealing strip 3 and move the sealing strip 3 into the receptacle of the opening element 1. By means of a positive connection between the sealing strip 3 and the receptacle of the opening element 1, this magnetic force ensures a tight seal.

The movement of the sealing strip 3 into the receptacle of the opening element 1 can, however, only be carried out in the embodiment shown if the opening element 1 is in its closed position and the receptacle of the opening element 1 with the receptacle for the sealing strip 3 provided on the stationary frame part 2a has a receiving channel form for the sealing strip 3, in which the sealing strip 3 is movable and positively guided in a direction R perpendicular to the sliding direction S of the sliding movement of the opening element 1.

A resetting movement of the sealing strip 3 in the direction of the stationary frame part 2a is carried out when at least some of the electromagnets 4.i are activated, that is to say by closing the switches 6.i assigned to them Flow of electricity. For this, in the embodiment shown, the electromagnets 4.i are organized in two groups, each second electromagnet 4.i (i = 1,3,5,... N) belonging to the electromagnets 4.i arranged in a row belonging to the first group, and the electromagnets 4.i (i = 2,4,6, ... N-1) in between of the second group. Activation of the first group of electromagnets 4.i generates a restoring force F that is oriented perpendicular to the direction of slide S (see Fig. 3 and Fig. 4b ) and in interaction with the permanent magnets of the sealing strip 3, the sealing strip 3 is moved from its tight contact into a position spaced from the opening element 1 ( Fig. 2b ).

By successively activating the electromagnets 4.i of the second group of electromagnets 4.i arranged in a row, a feed force F 'can subsequently be generated on the opening element 1, which is oriented obliquely to the sliding direction S (see Fig. 3 ) and in interaction with the permanent magnets of the opening element 1, the opening element 1 opens or closes.

If the current flow through the first group of electromagnets 4.i is interrupted, the interaction between the electromagnets 4.i and the permanent magnets of the sealing strip 3 is prevented. If the opening element 1 is in its closed position, the sealing strip 3 is subsequently moved again in the direction of the reception of the opening element 1 due to the interaction between the permanent magnets of the sealing strip 3 and the permanent magnets of the opening element 1. By reversing the current flow through the first group of electromagnets 4.i, this movement can be initiated, supported and / or the contact pressure in the receptacle of the opening element 1 can be varied.

Based on Fig. 4 a possible embodiment of the sealing arrangement according to the invention for a sliding door or a sliding window when the seal is closed ( Fig. 4a ) and with the seal open ( Fig. 4b ) explained. The opening element 1 designed as a sliding door or sliding window has triple glazing 8 and is on its lower edge on rollers 9 in the Sliding direction S is movably mounted, wherein a sealing body 10 can be provided. The rollers 9 are fastened on the stationary frame part 2a, which in turn has an angular support and is covered on its upper side with a sealing body 10. The sealing body 10 can be designed, for example, as a rubber seal or PUR seal and, together with the angular support, forms the receptacle for the sealing strip 3.

The Fig. 5 shows an embodiment of a sealing arrangement according to the invention in a specific installation situation for an opening element 1 designed as a sliding window. The opening element 1 in turn has triple glazing 8 and is movably mounted on its lower edge on rollers 9 in the sliding direction S, wherein a sealing body 10 can be provided . The rollers 9 are fastened on the stationary frame part 2a, which in turn has an angular support and is covered on its upper side with a sealing body 10. The sealing body 10 can in turn be designed as a rubber seal or PUR seal and, together with the angular support, forms the receptacle for the sealing strip 3. The sealing body 10 also closes flush with a window sill 11 which is fastened to a masonry 12 of the building opening. The masonry 12 is provided with a ventilated facade 13, which allows a draft L. A drip tray 14 is also provided on the stationary frame part 2a, on which moisture can drain off.

The sealing arrangement can also be connected to a control device, which according to the sliding movement of the opening element 1 and the movement of the sealing strip 3 between the tight system Fig. 4a and the position spaced apart from the opening element 1 Fig. 4b sensor controlled. By opening and closing the opening element 1 controlled by sensors, automated ventilation is possible, for example, which can significantly reduce the ventilation energy and the overall energy requirement of the building. Operation can be carried out using simple controls in the vicinity of the corresponding building opening take place, or also remotely controlled by appropriate mobile phone applications ("Apps").
