Abstract

The system has a sealing device (11) comprising magnets (14a, 14b), which move a sealing strip (12) based on position of a door wing (2) and are arranged at the sealing strip. The magnets cooperate with other magnets (15a, 15b, 17a, 17b) in a position of the wing, where the latter magnets are arranged at the door wing. The sealing strip is pressurized in a sealing position. The former magnets cooperate with third magnets (16a, 16b) in a position of the wing, where the third magnets are arranged at the wing. The sealing strip is pressurized in a non-sealing position.

Description

The invention relates to a door system according to the preamble of patent claim 1.

From the DE-OS 23 19 399 is a door system with at least one movably mounted door known. A sealing device is provided for sealing the door leaf with respect to an adjacent component of the door system, wherein the sealing device has at least one sealing strip movable between a sealing position and a non-sealing position. The sealing device also has at least one first, arranged on the sealing strip and the sealing strip depending on the position of the door leaf moving magnet. The sealing strip, which is arranged sunk in the ground, is raised by the attractive force of a second, arranged in the door magnet when the door is above the sealing strip, for example in the closed position of the door leaf. When the door leaf is again moved out of this sealing position, the magnets also come out of their attractive force, and the sealing strip falls back into its recessed position in the ground by the action of gravity. To release the attractive force of the magnets, a high expenditure of force is required, since the high static friction of the magnetically attracted to the door sill edge sealing strip must be overcome. Especially with manually operated door, this has a negative effect on the comfort of the door system. But even with automatic door systems, this effect may be undesirable because a higher drive power must be installed, as would actually be required for the movement of the door leaf. Furthermore, the sealing strip may jam before reaching its sunk in the ground position and thus represent a trip hazard.

The invention has for its object to provide a door system whose door has a functionally reliable at low operating forces sealing device.

The object is solved by the features of patent claim 1.

The subclaims form advantageous embodiments of the invention.

According to the invention, in at least a first position of the door leaf, the first magnet interacts with at least one second magnet arranged on the door leaf, which acts on the sealing strip in its sealing position, and at least in a second position of the door leaf the first magnet interacts with at least one third, magnet arranged on the door leaf, whereby the sealing strip is acted upon in its non-sealing position. This arrangement has low operating forces on a high reliability.

The sealing strip is two-dimensionally displaceable in the plane of the door leaf and mounted immovably perpendicular to the door leaf level with respect to the door leaf.

The sealing strip has at least one operating portion, which projects beyond the extent of the door leaf in the non-sealing position of the sealing strip in the direction of movement, in particular the closing direction of the door leaf. This makes it possible to dispense with bottom-side sealing elements, as disadvantageously present in the prior art.

The sealing strip is displaceable such that the first magnet cooperates in a first position of the sealing strip with the second magnet arranged on the door leaf and in a second position of the sealing strip with the third magnet arranged on the door leaf. This "floating", caused by the attraction or repulsion forces of the magnets guiding the sealing strip minimizes the operating forces, since no friction occurs.

For loading the sealing strip in a basic position, a return element may be provided. This also serves the functional safety.

The door system can be designed, for example, as a sliding door system, revolving door system or the like.

In the following, exemplary embodiments are explained in more detail in the drawing with reference to FIGS.

In the Fig. 1 a and 1 b is designed as a sliding door system door system 1 is shown in front view in the open position or in the closed position of the door leaf 2. Trained as a sliding leaf door 2 is slidably mounted along a fixedly arranged on a building ceiling 9 guide rail 8 via a guide means 5. The closable by the door 2 passage area of the door system 1 is bounded laterally by building walls 10. The guide device 5 has two roller carriages 6 with rollers 7, which roll in the guide rail 8. The suspended on the guide device 5 door 2 has a circumferential profile 3. A mounted on the profile grip device 4 is used for manual operation of the door leaf 2. Alternatively or additionally, a power-operated displacement of the door leaf 2 by a drive device is conceivable. In the area of the building floor 13, the door leaf 2 can likewise have a guide device, which can serve for the bottom-side guide and / or locking, but is not shown here. Furthermore, the door leaf 2 in the region of the building floor 13 has a sealing device 11, which serves to seal the bottom-side horizontal lower edge of the door leaf 2 with respect to the building floor 13 in the closed position of the door leaf 2. The sealing device 11 has for this purpose a movable sealing strip 12.

In the position according to Fig. 1a is the door leaf 2 in the fully open position, and accordingly, the sealing strip 12 of the sealing device 11 is in a raised position, so that between the lower edge of the Sealing strip 12 and the surface of the building floor 13 a small gap remains, which allows unimpeded movement of the door leaf 2.

In the position according to Fig. 1b is the door leaf 2 in the fully closed position, and accordingly, the sealing strip 12 of the sealing device 11 is in the lowered position, so that the lower edge of the sealing strip 12 sealingly rests on the surface of the building floor 13. The lowering or raising the sealing strip 12 is carried out depending on the position of the door leaf 2 and will be described in more detail below.

In the Fig. 2 the lower, the sealing device 11 receiving portion of the door leaf 2 is shown. The profile 3 of the door leaf 2 has in its essential extent a surface area 3 a, which can surround a plate-shaped component, for example a glass pane. At the lower horizontal edge of the door leaf 2, the profile 3 has a receiving region 3b, which can be designed as a downwardly open groove and accommodates the components of the sealing device 11. In the receiving area 3b, the sealing strip 12 in the plane of the door leaf 2 is two-dimensionally displaceable and perpendicular to the plane of the door leaf 2 immovably mounted relative to the door 2. Integral with the sealing strip 12, an actuating portion 12a is formed, which projects beyond the front side of the extension of the door leaf 3 addition. Alternatively, the actuating gate 12a may be formed as a separate, connected to the sealing strip 12 component. During the movement of the door leaf 2, the operating portion 12a comes with an adjacent component of the door system 1, for example, a not shown adjacent door or a fixed building wall 10, in Appendix, when the door 2 enters the position in which the sealing strip 12 of their non-sealing position is to be moved to its sealing position, for example in the closed position of the door leaf second

Not shown in this view is a flexible sealing element, for example rubber seal, which is preferably U-shaped and the entire opening of the receiving area 3b including the sealing strip 12 tightly encloses. In the illustrated operating state, the sealing strip 12 is in retracted Condition within the receiving area 3b of the door leaf 2. Here, the sealing element must be dimensioned in terms of its dimensions and / or flexibility so that it allows the entire path of movement of the sealing strip 12 from the fully retracted to the fully extended position without significant mechanical resistance.

Two magnets 14a, 14b are mounted on the sealing strip 12 by means of two holders 19, each having a north pole 14n directed downwards and an upward south pole 14s. A mounted on the sealing strip 12 stop 18 limits the range of movement of the sealing strip 12 upwards. A restoring element 21 supported on the profile 3 of the door leaf 2, for example a compression spring, urges the sealing strip 12 into a basic position, ie to the effect that the actuating section 12a, as is expedient in the retracted position of the sealing strip 12, moves in the direction of movement, in particular the closing direction of the Door leaf 2 extends beyond the extension of the door leaf 3 addition. In the receiving area 3b of the profile 3 of the door leaf 2 a plurality of magnets 15a, 15b, 16a, 16b, 17a, 17b are arranged. Four magnets 15a, 15b, 16a, 16b are arranged above the magnets 14a, 14b mounted on the sealing strip 12, while the two further magnets 17a, 17b are arranged below the magnets 14a, 14b mounted on the sealing strip 12. In the in Fig. 2 shown position of the sealing strip 12 are mounted on these magnets 14a, 14b below two in the same direction oriented, ie with overhead south pole 16s and bottom north pole 16n on the door 2 mounted magnets 16a, 16b. The magnets 14a, 16a, 14b, 16b are thus in mutually attractive effect and pressurize the sealing strip 12 upwards. In each case, in addition to these top-side magnets 16a, 16b, magnets 15a, 15b oriented in opposite directions, that is to say with the north pole 15n lying above and the south pole 15s lying underneath, are arranged. These become effective when the sealing strip 12 is pushed by the actuator 12a into the receiving area 3b of the profile 3 of the door leaf 2, wherein the mounted on the sealing strip 12 magnets 14a, 14b then below the oppositely oriented magnets 15a, 15b. Due to the then opposite south poles 14s, 15s, the sealing strip 12 is then applied downward. In order to increase the contact pressure of the sealing strip 12 with respect to the building floor 13, the two further magnets 17a, 17b mounted below the oppositely oriented magnets 15a, 15b, but with the same orientation as the mounted on the sealing strip 12 magnets 14a, 14b, ie with 17s overhead South Pole and below 17n North Pole. These lower magnets 17a, 17b are effective when the sealing strip 12 is pushed by the actuator 12a in the receiving area 3b of the profile 3 of the door leaf 2, in which case mounted on the sealing strip 12 magnets 14a, 14b above the lower magnets 17a, 17b and are attracted by these. The underlying magnets 17a, 17b thus support the overhead magnets 15a, 15b when the sealing strip 12 is acted upon against the building floor 13. If this is not necessary, either the lower magnets 17a, 17b or the overhead magnets 15a, 15b may be dispensed with become.

In the illustrated embodiment, there are two groups of magnets 14a, 15a, 16a, 17a, 14b, 15b, 16b, 17b respectively. In particular, in the case of long sealing strips 12, additional magnet groups interacting in this way can be additionally provided along the longitudinal extent of the sealing strip 12.

The FIGS. 3a to 3d show the movement of the extension of the sealing strip 12 during the closing movement of the door leaf second

The Fig. 3a shows a first operating state in which the door leaf 2 is in the partially open position and is moved in the closing direction (arrow A). The sealing strip 12 is acted upon by the restoring element 21 in such a way that the magnets 14a, 14b mounted on the sealing strip 12 are located below the upper magnetons 16a, 16b of the door leaf 2 oriented in the same direction and thus attracted thereto, ie the sealing strip 12 is in the held raised position.

The Fig. 3b shows a second operating state in which the door 2 is already close to its closed position. The actuating portion 12a of the sealing strip 12 is now in contact with the building wall 10.

Another movement of the door leaf 2 (arrow B) leads to the operating state according to Fig. 3c in which the actuating portion 12a is already partly inserted into the receiving area 3b. The magnets 14a, 14b mounted on the sealing strip 12 are now located between the upper magnetons 16a, 16b oriented in the same direction and the magnet pairs formed from the upper, oppositely oriented magnets 15a, 15b and the lower, magnetically oriented magnets 17a, 17b the sealing strip 12 is pushed or tightened on further movement of the door leaf 2 in the closing direction (arrow C) downwards (arrow D).

The closed position of the door leaf 2 is in the operating state according to Fig. 3d reached. The magnets 14a, 14b mounted on the sealing strip 12 are now located completely between the magnet pairs formed from the upper, oppositely oriented magnets 15a, 15b and the lower magnets 17a, 17b oriented in the same direction, so that the sealing strip 12 bears against the building floor with maximum force 13 is applied.

A subsequent, not shown here, opening movement of the door leaf 2 in principle leads to a reverse movement of the sealing device 11, in which case the actuating portion 12a is pushed back from the receiving area 3b under relaxation of the return element 21 and the sealing strip 12 associated magnets 14a, 14b through the upper, in the same direction oriented magnets 16a, 16b are raised.

In the Fig. 4 is the lower, a modified version of the sealing device 11 receiving area of the door leaf 2 shown. Deviating from the embodiment according to Fig. 2 and 3 extend the magnets 14, 15, 17 over approximately the entire width of the door leaf 2, wherein the north and south poles 14n, 14s, 15n, 15s, 17n, 17s are each directed in sections alternately upwards or downwards. While a magnet 14 is movable together with the sealing strip 12 relative to the door leaf 2, the other two magnets 15, 17 are arranged on the door leaf 2, wherein the fastenings of the magnets 14, 15, 17 on the sealing strip 12 and the door 2 are not shown here for reasons of simplicity.

The FIGS. 5a to 5d show the movement of the extension of the sealing strip 12 during the closing movement of the door leaf second

The Fig. 5a shows a first operating state in which the door leaf 2 is in the partially open position and is moved in the closing direction (arrow A). The sealing strip 12 is acted upon by the return element 21 so that the mounted on the sealing strip 12 magnet 14 is located below the same direction oriented portions of the upper magnet 15 of the door leaf 2 and thus is attracted by this, ie the sealing strip 12 is in the raised position held.

The Fig. 5b shows a second operating state in which the door 2 is already close to its closed position. The actuating portion 12a of the sealing strip 12 is now in contact with the building wall 10.

Another movement of the door leaf 2 (arrow B) leads to the operating state according to Fig. 5c in which the actuating portion 12a is already partly inserted into the receiving area 3b. The mounted on the sealing strip 12 magnet 14 is now between the same direction and the oppositely oriented portions of the upper magnet 15 and the lower magnet 17, so that the sealing strip 12 repelled in further movement of the door leaf 2 in the closing direction (arrow C) down or is tightened (arrow D).

The closed position of the door leaf 2 is in the operating state according to Fig. 5d reached. The mounted on the sealing strip 12 magnet 14 is now completely between the oppositely oriented portions of the upper magnet 15 and the same direction oriented portions of the lower magnet 17, so that the sealing strip 12 is acted upon with maximum force against the building floor 13.

A subsequent, not shown here, opening movement of the door leaf 2 in principle leads to a reverse movement of the sealing device 11, in which case the operating portion 12a is pushed back from the receiving area 3b under relaxation of the return element 21 and the sealing strip 12 associated magnet 14 by the same direction oriented portions of the upper magnet 15 is raised.

The Fig. 6a and 6b show in sectional view the lower portion of the door leaf 2, which according to Fig. 4 and 5 formed sealing device 11 receives, in two operating states.

In the operating state according to Fig. 6a is the sealing strip 12, which is enclosed below and laterally by a U-shaped sealing element 12b, in the raised position. In the receiving area 3b of the profile 3 of the door leaf 2, a receiving profile 22 is mounted, which has two receiving spaces 22a, 22b. In this sectional plane, which is the XX line of the Fig. 5a is disposed in the upper receiving space 22a, a portion of the upper magnet 15 with overhead south pole 15s and bottom north pole 15n, and in the lower receiving space 22b, a portion of the lower magnet 17 with overhead north pole 17n and bottom south pole 17s is arranged. In the existing between the receiving spaces 22a, 22b of the receiving profile 22 free space projects a receiving space 12c of the profile of the sealing strip 12 in which in this sectional plane, a portion of the magnet 14 is arranged with overhead south pole 14s and bottom north pole 14n. The sections of the magnets 14, 15 visible in this sectional plane are oriented in the same direction, whereby the magnets 14, 15 are in attractive relationship to each other, and the sections of the magnets 14, 17 visible in this section plane are oriented in opposite directions, whereby the magnets 14, 17 in repel each other, so that the sealing strip 12, as shown, is raised.

In the operating state according to Fig. 4b is the sealing strip 12 in the lowered position. In the illustrated section plane, which is the line YY of Fig. 5d is in the upper receiving space 22 a of the receiving profile 22nd the door leaf 2, a portion of the magnet 15 with overhead north pole 15n and bottom south pole 15s arranged. In the lower receiving space 22b, a section of the magnet 17a is arranged in this sectional plane with the south pole 17s above and the north pole 17n below. In the engaging between the receiving spaces 22a, 22b of the receiving profile 22 receiving space 12c of the profile of the sealing strip 12 a portion of the magnet 14a is arranged with overhead south pole 14s and bottom north pole 14n in this sectional plane. The sealing strip 12 associated magnet 14 and the lower magnet 17 of the door leaf 2 are oriented in the same direction, while the upper magnet 15 of the door leaf 2 is oriented in opposite directions. As a result, the sealing strip 12 associated magnet 14 is repelled by the upper magnet 15 of the door leaf 2 and attracted by the lower magnet 17 of the door leaf 2, so that the sealing strip 12, as shown, is lowered in the direction of the building floor 13.
