Description

Technical area

The invention relates to a lowerable sealing device according to the preamble of patent claim 1 and to a door or a window according to the preamble of patent claim 9.

State of the art

Automatically lowerable sealing devices are known. They are generally used for threshold-free doors to seal the lower gap between the door leaf and floor against draft, sound and light transmission. A generic sealing device is in EP 0 338 974 disclosed. The actuation of the sealing device takes place automatically when closing and opening the door. Examples of corresponding lowering mechanisms are in EP 0 509 961 and DE 19 516 530 described and in the FIGS. 1a and 1b shown.

In a U-shaped, downwardly open guide rail 1, a sealing strip with a support rail 2 and attached thereto, not shown here sealing profile is lowered and raised. For this purpose, an actuating knob 4 'protrudes from the end face of the guide rail 1, which is connected via an actuating rod 40' with a power transmission rod, here called push rod 5. A leaf spring 6 is connected to the pressure rod 5 with a first end 60. In the central region 61, it is on the support rail 2 and with a second end 62nd pivotally attached to the guide rail 1. Further springs can then be arranged on this first leaf spring 6 and fastened in the same way. As a result, the sealing device can be actuated on one side when opening and closing the door. In FIG. 1a the door seal is shown in the open state of the door. The operating knob 4 'protrudes from the guide rail 1 and the sealing strip is raised. In FIG. 1b it is shown in the closed state of the door. The actuating button 4 'is pressed against a door frame, not shown, so that the actuating rod 40' and the push rod 5 were pressed into the guide rail. As a result, the prestressed leaf springs 6 were pressed down and lowered the sealing strip.

Other types of lowering mechanisms are also known in the prior art, which actuate the seals on one or two sides, but always on the front side. For example in DE 35 26 720 . DE 34 18 438 and DE 34 27 938 ,

DE 31 24 106 A1 discloses a lowering seal to be triggered on both sides and by means of pressure with band springs and compression springs.

DE 195 16 530 discloses a lowering spring to be triggered on one side, in which by pressure on a confirmation rod, a leaf spring is curved and the sealing strip is lowered.

AT 398 329 describes a sealing device at the lower end of a wing of a window or a door, wherein the sealing means comprises a movable sealing strip.

Presentation of the invention

It is therefore an object of the invention to provide a lowerable sealing device which allows greater flexibility in the choice of the triggering mechanism.

This object is achieved by a lowerable sealing device having the features of patent claim 1.

The erfmdungsgemässe seal according to claim 1 can be triggered by train on a power transmission rod.

The inventive sealing device comprises a guide rail, a held in the guide rail, lowerable and liftable sealing strip, a first power transmission rod which extends in the longitudinal direction of the guide rail and is slidably held in this in its longitudinal direction, at least one spring comprising a lowering element, which in the guide rail is arranged, which is connected to the sealing strip and which is actuated by means of the first power transmission rod for the purpose of lowering the sealing strip. The lowering element has a position which is held displaceably in relation to the guide profile rail in this. The first power transmission rod is connected to a driver which entrains this point of the Absenkelements in longitudinal displacement of the first power transmission rod in a first direction and does not entrain this displaceable position of the Absenkelements in longitudinal displacement of the first power transmission rod in a second, opposite direction.

The lowering element may consist exclusively of a lowering spring, in particular a leaf spring. However, it may also be, for example, a combination of rods, slides and springs, such as coil springs.

In one embodiment, the lowerable sealing device according to the invention has a guide profile rail, a lowerable and liftable spring-loaded sealing strip held therein, and at least one, preferably exactly one, triggering element for raising and lowering the sealing strip. The sealing strip is raised in a basic position of the trigger element and lowered in a first triggering position of the trigger element. According to the invention, the triggering element has a second triggering position, which is different from the first, wherein the sealing strip is also lowered in this second triggering position.

Preferably, the movement of the trigger element is parallel to the longitudinal axis of the guide rail, i. the trigger element is moved. However, it is also possible for it to be panned or to perform another movement.

The basic position is preferably located between the first and second triggering positions, in particular centrally therewith. However, it is also possible for the first and second triggering positions to lie on the same side of the basic position, one of which is further away from the basic position than the other.

The sealing device according to the invention preferably has a guide profile rail and a lowerable and liftable sealing strip held therein. The sealing strip is spring-loaded and can be lowered by displacing a triggering element from a basic position in a first direction. It can also be lowered by displacement of the triggering element in a second direction opposite the first direction, wherein the sealing strip is raised when the actuating rod passes through the basic position.

According to the invention, it is now possible that the sealing device is lowered automatically either by train or by pressure on the actuating rod. Depending on the release mechanism, only one of these two possible strokes or both strokes can be used. When both strokes are used, the seal is activated at two different positions of the trigger mechanism.

This is advantageous for example for doors or windows, which not only open and close by a single operating lever, but also tilt. Thus, the lower portion of the window or door can also be sealed in the tilted position. As a result, it is possible to successfully prevent water from entering the building in the event of rain, in particular driving rain, even if the window or the door is only tilted.

In one embodiment, the lowerable sealing device comprises the guide profile rail, held in the guide rail lowerable and liftable sealing strip, the first power transmission rod which extends in the longitudinal direction of the guide rail and is slidably held therein in its longitudinal direction, and the at least one Absenkfeder, which is attached at their ends and which approximately in its center the sealing strip is attached. The at least one Absenkfeder extends between these attachment points inclined to the longitudinal direction of the guide rail and loaded the sealing strip in its raised state. In this embodiment, the Absenkfeder is fixed in position at its first end to the guide rail or with respect to the guide rail mounted on a second power transmission rod and the Absenkfeder is slidably mounted at its second end in the longitudinal direction of the guide rail on the guide rail. The first power transmission rod is connected to the driver, which in longitudinal displacement of the power transmission rod in a first direction entrains the longitudinally displaceable second end of the Absenkfeder and leaves in longitudinal displacement of the power transmission rod in a second, opposite direction, the second end of the Absenkfeder.

This allows automatic release of the seal by train. This arrangement may, but need not, be associated with a release by pressure. In the second case results in a Doppelhubauslösung.

In a further preferred embodiment, the sealing device comprises a guide profile rail, a lowerable and liftable sealing strip held in the guide profile rail, a force transmission rod which extends in the longitudinal direction of the guide profile rail and is held displaceably in its longitudinal direction, at least one lowering element comprising a spring is connected to the sealing strip and which by means of the power transmission rod for the purpose of lowering the sealing strip is actuated. The guide rail has a window for connecting an operating rod to the power transmission rod, wherein the window is arranged so that the connection takes place in an approximately perpendicular direction to the longitudinal direction of the guide rail.

Again, the Absenkelement can consist exclusively of a leaf spring.

In a further embodiment, the lowerable sealing device according to the invention comprises a guide profile rail, a lowerable and liftable sealing strip held in the guide profile rail, a force transmission rod which extends in the longitudinal direction of the guide profile rail and is held displaceably in its longitudinal direction, and at least one lowering spring, which is connected to the Guide rail, the sealing strip and the power transmission rod is connected or operatively connected. This Absenkfeder extends between these attachment points inclined to the longitudinal direction of the guide rail and loaded the sealing strip in its raised state. In this embodiment, the guide rail has a window for connecting an operating rod to the power transmission rod, wherein the window is arranged so that the connection takes place in an approximately perpendicular direction to the longitudinal direction of the guide rail.

The triggering of the lowering mechanism is thus not the end face at the end or outside the guide rail but within its length. The location of the trigger may be adjacent to an end. However, it may also be in the middle or another area along the length of the guide rail. In addition, this arrangement can be used for pure Zugauslösungen, pure pressure releases or combinations thereof.

It is a further object of the invention to provide a door or window with thermally separated profiles and a locking mechanism in the threshold area, which is as dense as possible and yet has a relatively low threshold. The threshold of the door or the window should in particular be a maximum of 20 mm and thus be handicapped accessible.

This object is achieved by a door or a window having the features of patent claim 9.

The door according to the invention or the window according to the invention has a frame, at least one door or window wing and a locking mechanism which locks at least below in the region of the threshold. The frame has thermally separated profiles. According to the invention, the door or the window has a sealing device which can be lowered or raised according to the invention when closing or opening the door or window sash.

By using this sealing device, the associated frame area can be made relatively low and thus suitable for the disabled. It still protects reliably even against driving rain.

If a sealing device according to the invention is used whose location of release is within the length of the longitudinal profile rail, the normal window lever can be used to actuate the sealing device. This means that when opening and closing the window or the door of this lever, the sealing strip raises or lowers.

If a sealing device according to the invention with the double stroke described above is used, the seal can be lowered not only when the window or door is closed, but also in a second closure position, in particular when the window or tilted door is tilted.

Further advantageous embodiments will become apparent from the dependent claims.

Ways to carry out the invention

In the FIGS. 2a to 2e a first embodiment of a lowering seal is shown, which is automatically triggered. The sealing device is not visible in its entire length. Furthermore, only a single Absenkfeder is shown. However, the device usually has a plurality, preferably two Absenkfedern, which are arranged one behind the other in the longitudinal direction of the seal.

In FIG. 2a is shown a side view of the sealing device, wherein the parts located in the interior of the housing are shown with thinner lines.

The housing is formed by a U-shaped, downwardly open guide rail 1, which has two parallel side walls and an upper web. It is usually made of aluminum. In the interior of the guide rail 1 is an in FIG. 2a Not shown sealing strip held raised and lowered. The sealing strip includes, as in the Figures 2c and 2e is best seen, a rigid support rail 2, preferably made of aluminum, and a thereto attached elastomeric sealing profile 3, which in FIG. 2e is shown.

According to FIG. 2a the guide profile rail 1 has a passage opening or a Window 10 on. This window 10 may be arranged in a side wall in an end region of the rail 1 and located adjacent to the upper web. However, it may also be arranged, for example, in the middle region of the rail, also preferably in the region of the upper web, or at another suitable location. Preferably, only one window 10 is present. However, it is also possible, for example, to arrange several windows on the same, on opposite sides and / or in the upper web. The windows can vary depending on the application, but they do not have to be aligned with each other.
Preferably, the window 10 is rectangular in shape, extending with its longitudinal direction in the longitudinal direction of the guide rail 1. Other shapes are also possible.

In the interior of the guide rail 1 is at least one Absenkfeder, preferably two Absenkfedern are arranged. They are preferably designed as flat leaf springs 6, which extend in the longitudinal direction of the guide rail 1. These lowering springs are often referred to as bending springs.

Furthermore, in a groove 11 formed by the upper web and two projecting ribs or noses of the guide rail (see FIG. 2e ), a power transmission rod 5 is arranged. This example is a push rod as known in the art. It preferably has a rectangular cross section and is formed flat. It extends approximately over the entire length of the guide rail 1, wherein it may be one or more pieces. This power transmission rod 5 is often referred to as a basic spring.

Each leaf spring 6 is now attached to a first end 60 on the push rod 5, here by means of a screw or a rivet. In its central region 61, each leaf spring 6 is attached to the sealing strip, more precisely to the carrier profile rail 2. This is done here by means of a plastic part, which is einklippsbar on both sides in the carrier rail 2 and which has a passage opening for the leaf spring 6. In this case, the leaf spring 6 is preferably held immovably therein. With its second end 62, the leaf spring 6 is fixed to the guide rail 1, wherein they are in a plastic part is held, which is pivotally mounted in the guide rail 1.

One end of the push rod 5 is connected to a triggering element or trip block 7, which projects away from the push rod 5 down into the cavity of the guide rail 1. For example, it is screwed to the push rod 5 by means of screws 71, as shown in FIG Figure 2d is recognizable. Other types of fastening are possible.

The trip block 7 is located in the region of the window 10 and behind this. This is according to FIG. 2a adjacent to the region where the first end 60 of the leaf spring 6 is attached to the push rod 5.

This block 7 is preferably made of plastic. However, it can also consist of another material, in particular metal. The trip block 7 preferably has a cuboid basic shape. It is provided with a receiving opening 70 which is directed towards the window 10 of the guide rail 1, so that access to the opening 70 is ensured by the window 10. The receiving opening 70 preferably has an oval shape. It may alternatively have other shapes.

In this receiving opening 70 can be an end of an operating rod 4 introduce. This is in FIG. 2e recognizable. The rod can be straight or angled. In FIG. 2a the bar 4 is hatched. As can be seen there, the receiving opening 70 is larger than the diameter of the rod 4. This facilitates the insertion of the rod 4 in the opening 70 of the mounted device. Preferably, the opening 70 at least in the longitudinal direction of the guide rail 1 is greater than the corresponding dimension of the rod 4. Instead of a receiving opening 70 in the form of a passage or blind hole and a different connection form can be selected. For example, the opening 70 may be fork-shaped, which encloses the end of the actuating lever.

In the FIGS. 2b and 2c It is now apparent how the triggering mechanism works. In principle, the lowering and raising takes place the same as in the above-mentioned state the technology, especially in DE 19 516 530 , However, it is not the end of a pressure exerted on the push rod 5, but the triggering takes place laterally and especially within the length of the guide rail. 1

By movement of the actuating rod 4 from right to left of the trip block 7 and thus the push rod 5 is pushed to the left or pushed. The first end 60 of the leaf spring 6 is also pushed to the left, wherein the second end 62 fixed in position remains relative to the guide rail 1 and is pivoted only downwards. The leaf spring 6 is tensioned and the central region 61 and the sealing strip 2, 3 are lowered. This condition is in Figure 2c shown. In this case, the left end of the window 10 serve as a stop. The right end of the window 10 may, but does not have to, serve as a stop for the counter-directional movement, ie when the seal is raised again.

If two or more leaf springs 5 are present, then the second or the further springs can connect on the left side. But it is also possible that the window 10 and the trip block 7 is disposed between two springs. The push rod 5 extends in this case on both sides of the trip block 7, i. this is not attached to one end of the push rod 5, but in its middle or another area. However, the springs 6 are fastened in an analogous manner to the pressure rod. That the spring 6 located on the right side of the trip block 7 is connected to the push rod at its end remote from this block. With its end near this block, it is in turn attached to the guide rail 1 via a hinge. In this case, the spring located on the right side of the trip block 7 is not triggered by pressure but by train. Therefore, in this case, the term power transmission rod is better used instead of compression rod.

Furthermore, as already mentioned, the window 10 can also be arranged on both opposite sides of the guide profile rail so that the release block is accessible on both sides. As a result, the same actuation of the seal can be initiated either individually or jointly from either side. The first case allows the same type of seal for right and left casements to use. When released together and at the same time, power transmission is improved. However, if triggered on both sides with a time delay, then a first lowering from one side and a second lowering from another side can be achieved by different triggering means or different movements of the same triggering means. The same applies if several windows are arranged on the same side of the seal or in the upper web. This significantly increases the flexibility in the application of the seal.

Alternatively, the window 10 may be arranged in the upper web of the guide rail 1, so that the release is not laterally but from above.

In the FIGS. 3 to 6 an embodiment of the invention is shown. The basic structure of the sealing device is the same as in the above example. The same parts are therefore provided with the same reference numerals and will not be described in detail. Again, at least one, preferably two Absenkfedern 6 are present. As in FIG. 3a can be seen, each spring 6 is fixed with a first end 60 on the push rod 5. With its central end 61, it is firmly connected to the carrier rail 2. Its second end 62 is in turn pivotally held in the guide rail 1. In addition, however, this second end 62 is held displaceably in the longitudinal direction of the guide rail 1. For this purpose, the rail 1 in each side walls each have a slot 12 which are opposed to each other and which extend in the longitudinal direction of the guide rail 1.

In addition to the pressure rod 5, a second power transmission rod is present, which is here called tension rod 9. It is preferably the same design as the push rod 5, ie with a rectangular cross-section and flat. Preferably, it runs parallel and above the push rod 5. However, it can also extend below or laterally thereto. An arrangement of the two rods 5, 9 one above the other has the advantage that the sealing device can still be made very narrow. As in the Figures 6a and 6b It can be seen that the guide profile rail 1 for this purpose preferably has two grooves 11 ', 11 "arranged one below the other and adjacent to the upper web, which are formed on both sides by inwardly projecting longitudinal ribs of the side walls The pressure rod 5 is also held displaceably in the longitudinal direction in the lower groove 11 ". Again, both bars 5, 9 are preferably made of metal, in particular steel.

Again, a trigger element or trip block 7 is provided, which is arranged in the region of the window 10 of the guide rail 1. In contrast to the above example, this trip block 7 is now not attached to the compression spring 5, but to the tension spring 9. This can in turn be done by means of screws 71 or other types of fastening. The trip block 7 in turn has at least one receiving opening 70, in which an actuating rod 4 can be inserted to move the trip block 7 within the permitted range through the window 10 to the right or to the left and so the pull rod 9 within the guide rail 1 move.

In FIG. 3a and more precisely in the FIG. 4a can be seen that the trip block 7 passes through the push rod 5. For this purpose, the push rod 5 has a first passage opening 50, which is designed to be longer in the longitudinal direction of the guide profile rail 1 than the trigger block 7. Behind the or right of the trip block 7, a stop 8 is present. This is attached to the inside of the web of the guide rail 1, in particular screwed. Preferably, it is a block-shaped block. It can be made of metal, plastic or other suitable material. The stopper 8 protrudes sufficiently deep down to stop the movement of the push rod 5 in the direction to the right, ie from the trip block 7, away.

Another difference to the lowering seal described above is present on the left side of the leaf spring 6. Here, a driver 91 is fixed in position on the pull rod 9 fastened, preferably by means of a screw 90. This driver may also be formed as a substantially block-shaped block made of plastic or metal. Other shapes are also possible. Preferably, it has a part-spherical recess 92 towards the leaf spring 6, which corresponds to the outer contour of the rotary joint of the second end 62 of the leaf spring 6.

The push rod 5 has in this area a second passage opening 51, which is penetrated by the driver 91. The second passage opening 51 is formed longer in the longitudinal direction of the guide rail 1 than the driver 91.

In FIG. 3a It can be seen that the actuating rod 4 in turn engages laterally within the length of the guide rail 1 through the window 10 in the lowering mechanism and this actuated by displacement of the trip block 7 to the right or to the left. FIG. 4a shows that the trip block 7 passes through the push rod 5 ineffective. FIG. 5a shows that in this position, the driver spaced from the second end 62 of the leaf spring 6 is arranged and this second end 62 is located on the left, the trip block 7 far end of the slot 12.

In FIG. 3b is the sealing strip or the carrier rail 2 in its rest position and is raised. The spring 6 is preloaded and slightly bent, but exerts no force on the support rail 2 from. The in the FIGS. 4b and 5b illustrated situations correspond to those already above based on the FIGS. 4a and 5a described.

In Figure 3c the trip block 7 is pushed to the left until the operating rod 4 is present at the left end of the window 10. The spring 6 is stretched and the sealing strip 2, 3 is lowered. The exact situation is in the FIGS. 4c and 5c recognizable. The trip block 7 was, see Figure 4c , Now moved within the first passage opening 50 of the push rod 5 until it is present at the right boundary surface of the through hole 50. The trip block 7 is then used in its further shift to the left as a driver for the push rod. 5 As a result, as already in the above example, the first end 60 of the leaf spring 6 moved together with the push rod 5 to the left. The second end 62, which at the left end of the slot 12 already is pending, was pivoted as in the above example and the central portion 61 of the spring 6 has been lowered. With him also lowered the sealing strip 2, 3, which can now rest on the ground sealing. The pull rod 9 was indeed moved to the left. However, with him also moved the driver 91, which was even more remote from the second end 62 of the leaf spring 6. As a result, the movement of the tension rod 9 had no influence on the leaf spring 6, as in FIG. 5c is shown.

Now, if the trip block 7 is moved by means of the actuating lever 4 from this position to the right, so he goes through and thus the other moving parts of the seal back to the basic position according to the FIGS. 3a, 3b . 4a, 4b . 5a and 5b , The seal is thus raised again.

If, however, the triggering block 7 is moved further to the right by means of the actuating rod 4 beyond this basic position, the sealing strip again sinks to the ground. This is in 3d figure shown. Details are in the Figures 4d and 5d recognizable.

In the movement of the trip block 7 to the right now again the pull rod 9 and the push rod 5 were moved to the right. The push rod 5 was brought back into its original position by the restoring force of the spring 6. If now the trip block 7 is moved further to the right, so he pulls the pull rod 9 with. As a result, the cam 91 moves toward the second end 62 of the spring 6 as shown in FIG FIG. 5d is recognizable. He pushes the hinge or the second end 62 of the spring 6 to the trip block 7 and the center 61 of the spring 6 back. By this movement, the entire spring 6 is first pushed to the right and with it the push rod 5. However, this is soon at the stop 8, as in FIG. 4d is shown. If the triggering block 7 is now displaced further to the right within the range permitted by the window 10, the driver 91 can now push the second end 62 of the spring 6 further forward without the entire spring 6 also being displaced. The spring 6 is stretched again, the central region 61 lowers and the sealing strip 2, 3 is lowered again sealingly on the ground. The first and second passage openings 50, 51 must be large enough to allow these movements without affecting the pressure rod 5. In addition, they must be short enough to be as stop or effective surfaces for the driver 91 and the stop block 7 to serve so that they can be taken after a certain free displacement of these parts 91, 7 of them.

This arrangement thus enables a double stroke. That is, a lowering of the sealing strip takes place when moving from a central position both to the right and to the left.

Again, the window 10 and thus the engagement of the actuating rod 4 from the outside both on one side via a side wall of the guide rail 1, be arranged on both sides on both side walls and / or from above the upper web of the guide rail 1 or done. In particular, the double stroke can be triggered by the same window or by two different windows.

The window 10 can in turn be arranged in the region of an end face of the rail. If there are several, in particular two, springs, these are arranged in succession on one side of the window in the abovementioned case.

However, the window 10 may also be arranged here in the longitudinal direction of the rail 1 in the middle or in another suitable region of the guide rail 1. In this case, a first spring on the left and a second spring on the right side of the window and thus the trip block is arranged. They are arranged the same aligned one behind the other, that is, the second displaceable end of the second spring is adjacent to the trip block and the first end attached to the push rod is located in the trigger block remote area of the guide rail. Again, thus, the push rod 5 acts on this second spring as a tie rod and the tension rod 9 as a push rod. In this case, one speaks better of a first power transmission rod 9 and a second power transmission rod 5. Preferably, the operative connection between the first power transmission rod 9 and lowering spring 6 always via a driver and the operative connection between the second power transmission rod 5 and lowering spring 6 via a fixed connection, in particular by means of a Screw or a rivet.
Furthermore, the triggering of the lowering mechanism does not necessarily have to be within the length of the guide rail 1 lie. The triggering can also be done on the front side. For example, the trip block or the drive element can be provided with an eyelet into which the counterpart engages accordingly.

Furthermore, this arrangement can also be provided only with the pull rod 9, so that only one stroke is made possible by pulling.

The above-described two embodiments of the sealing devices are the same except for the inventive lowering mechanisms as in EP 0 338 974 . EP 0 509 961 and DE 19 516 530 described. In particular, the sealing profile is also integrally formed here and mounted on two opposite sides or centrally on the support rail, so that a lower arc is formed, which can rest on the floor sealing. The legs of the sealing profile, which extend above the attachment point, are each on one side of the guide rail sealingly to this. However, the inventive teaching is not only applicable to such sealing devices, but is also suitable for other types of seals, in particular other types of sealing profiles and lowering mechanisms. For example, the inventive teaching can also be applied to lowering mechanisms, such as those in DE 35 26 720 . DE 34 18 438 and DE 34 27 938 are disclosed.

These sealing devices are suitable for a wide variety of applications. The operating lever may be a separate lever, which is used only for actuating the lowering seal. Preferably, however, it is a lever which is also used to operate the door leaf or window or for a locking system coupled thereto. He may also be mechanically coupled with such a lever. The triggering is thus no longer mandatory by queuing a trigger button on a door frame but by an active movement of a lever, which is triggered manually or by motor.

The sealing device according to the invention is suitable not only for use in threshold-free doors but also for balcony doors or windows, in particular for lift-and-slide doors. The actuating lever 4, in particular in this case, the actuating lever, which allows opening, closing, locking and tilting of the door or the window sash.

The described guide rail 1 may be a separate part which is fixed in a corresponding groove of the door or window sash. But it can already be molded in the door or window sash and therefore be an integral part of the door or window profile. This is especially possible with metal and plastic windows.

In a particular application, the automatic lowering seals described above are used in a door or window having a lockable door or window sash and a frame comprising thermally separated profiles. The locking takes place in the lower horizontal area of the door or the window, either to tilt them or be it to ensure increased tightness or security against burglary.

The lowering seal is preferably arranged in the door leaf or window sash. The profile region of the frame below the Absenkdichtung can be relatively low, in particular 20 mm maximum formed. As a result, balcony doors or sliding doors can be adapted for the disabled with barely perceptible thresholds, without the tightness of the door or the window is reduced or the possibility of locking in the lower region or the thermal separation of the profiles is impaired.

If a seal is used which allows a double stroke, so the seal can be lowered not only when closing or locking the window or the door, but also when the door or the window is tilted. The lever of the window is brought into a first position to lock the window. At the same time he lowers the seal. A second position of the lever opens the window. He lifts the seal. A third position is used to tilt the window. He lowers the seal again. This allows a tilted window or a Door in the lower area still to seal, especially against driving rain, without a separate mechanism must be installed.

Instead of the seals described above can also be used for this other lowerable seals with single stroke or double stroke.

The inventive sealing device increases the flexibility in its application by the different types of triggering.
