Description

TECHNICAL AREA

The present invention relates to a sliding gate with at least one integrated in the sliding gate hinged wing door, a sealing unit for such a sliding gate and a lowering seal.

STATE OF THE ART

Lowering seals for doors are well known. They prevent light leaks, provide sound insulation and can also prevent air circulation, depending on the design. Lowerable door seals usually consist essentially of a housing in the form of a downwardly open, U-shaped rail, a held in this housing and relative to this sliding sealing strip with a sealing element and a drive mechanism for lowering or lifting the sealing strip. Usually, the sealing strip automatically lowers when closing the door by a compressive force acts in the longitudinal direction of an actuating rod or slide and sets the mechanical lowering mechanism in operation. Such door seals are made, for example EP 0 338 974 . DE 299 16 090 and EP 0 509 961 known.

Proven lowering mechanisms, which are triggered unilaterally, are, for example, in EP 0 509 961 and CH 688 741 described. These lowering mechanisms use one or more leaf springs arranged one behind the other. Each leaf spring is attached to the slider itself with a first end adjacent a housing projecting end of the slider. Each leaf spring is further with its central region on the sealing strip and with its protruding end of the slider far end of the housing attached. As a result, the pressure acting on the slider when closing the door pressure is transmitted to the leaf springs. These bend and lower the sealing strip.

Also EP 0 037 131 and DE 20 2011 001 104 U trigger the lowering mechanism via a pressure force.

However, hardly any sealing solutions are known for sliding doors with integrated hinged double doors, in particular for fire protection or smoke protection doors with escape doors.

DE 102 48 819 describes a sliding door with a rotary wing unit, wherein the rotary wing unit has a bottom seal. This bottom seal can be raised to pivot the door.

US 5,467,559 describes a sliding wall with an escape door, which has an electrically activated lowering seal.

EP 1 359 280 describes a sliding door system with pivoting wings, which are provided with a Absenkdichtung. The seal is activated by a frontally projecting trigger, which slides along the opening of the door along a gate of a cam.

DE 20 2007 007 569 U discloses a fire-resistant sliding door with a threshold-free escape door. The escape door is designed as a hinged door and has a unilaterally releasable lowering seal. So that the lowering seal can be lowered even when closing the sliding gate, a power transmission rod is arranged on or in the sliding door part, which presses on the trigger of Absenkdichtung.

DESCRIPTION OF PREFERRED EMBODIMENTS

In FIG. 1 is a sliding gate shown. Such sliding gates are used for closing wall openings, for example in case of fire or smoke or for room separation. The sliding gate has a base wing 10, which is guided guided by rollers 11 along a guide rail 12. The sliding direction for closing the wall opening, ie for closing the sliding gate, is shown with a large arrow.

In the base wing 10 at least one hinged door is arranged. Here, two gullwing doors 13, 14 are shown by way of example, which are separated from one another by a section of the basic wing 10. A first hinged door 13 is pivotable about a right-handed arranged pivot axis; a second wing door 14 via a left-handed arranged pivot axis.

The base wing 10 is at its lower end with several Absenkdichtungen with in FIG. 1 lowered sealing elements 30, 32, 34 provided. The two wing doors 13, 14 have lowering seals with sealing elements 31, 33 lowered in this figure.

In FIG. 2 is the second, in the closing direction of the first double door 13 subsequent gullwing door 14 shown in the open state. The associated sealing element 33 and the subsequent sealing in the closing direction of the base member 34 is thereby raised, the remaining sealing elements 32, 31, 30 are still sealing on the ground.

In FIG. 3 if the second wing door 14 is closed, the first hinged door 13 is open.

As a result, the associated lowering seal is raised and the corresponding sealing element 31 is no longer resting on the ground. The same applies to the following in the closing direction of the sliding gate sealing elements 32, 33, 34. Only the previous sealing element 30 is still lowered.

In FIG. 4 the entire sliding gate is open, wherein the wing doors 13, 14 lie in the area defined by the base wing 10 and thus are closed. The reference character O denotes a thus released wall opening O. In this state, all sealing elements 30, 31, 32, 33, 34 are now raised. The sliding gate can thus be easily from this position in this closed, in FIG. 1 shown position without any sealing elements 30, 31, 32, 33, 34 grind over the floor. Only when the sliding door is present at a lateral stop block 15, the Absenkdichtungen the individual sections 10, 13, 14 of the sliding gate are activated and the sealing elements 30, 31, 32, 33, 34 lowered. The trip block 15 is preferably on the door frame.

As Absenkdichtungen the known mechanically automatically lowerable seals can be used with one-sided, frontal release. Hereinafter, a preferred type of Absenkdichtung is described by way of example. Such door seals are made, for example EP 0 338 974 known.

The seal may be attached to a lower end face of the sliding gate. Preferably, it is attached in an end-side groove, for example screwed.

The lowering seal points, as in FIG. 5a can be seen, a seal housing 20 with a held therein, not visible here support rail. Housing 20 and rail are preferably made of an aluminum profile. Both are preferably U-shaped, wherein the housing 20 is open at the bottom and the support rail is preferably designed to be open at the top. On the support rail, a one-piece or multi-piece sealing element 30 is attached, which preferably consists of an elastomeric material, for example silicone.

The carrier rail is in common with the sealing element 30 relative to Seal housing 20 can be raised and lowered. For this purpose, a non-visible mechanically automatically activated lowering mechanism is present, as it is also known from the prior art. For example, reveal EP 0 509 961 . DE 19 516 530 . DE 35 26 720 such as DE 34 27 938 Lowering mechanisms with one-sided activation. The sealing elements of the individual door seals can be provided in the case of a fire door with inflating agents.

The seal is preferably on at least one, preferably on exactly one end face before a triggering element in the form of a spring-loaded actuating rod 40, which is present at the closing of the sliding gate on the side stop block 15 and is thereby pressed. This is in FIG. 5b shown. In FIG. 5c the arrow represents the closing movement of the sliding gate. The rod 40 is connected to a power transmission rod, which extends in the upper region of the housing 20. In the housing 20, one or more leaf springs are further held, which are fastened with their respective first end to the power transmission rod and with its respective second end to the housing 20. A middle region of the leaf springs is respectively attached to the carrier rail. When the operating rod 40 is pressed in, the leaf springs are compressed and the carrier rail is lowered. The sealing member 30 sealingly rests on the floor and closes the gap between the underside of the sliding gate and the floor. If the sliding gate is opened again, the leaf springs are relieved again and the carrier rail is lifted together with the sealing element 30 again. The first end of the actuating rod shown here is preferably designed as a plane stop surface.

The FIGS. 5a to 5c show the front seal in the closing direction of the door, more precisely its first end area. These are thus the first housing 20, the first sealing element 30 and the first actuating rod 40 is. This position is in FIG. 1 denoted by A.

The lowering mechanism of the second and subsequent seals is identical to that of the first seal and will therefore not be described again. The same applies to housing, carrier rail and sealing element. The individual seals preferably differ only by their lengths and by the final shapes of their actuating rods.

In the FIGS. 6a to 6b the opposite end portion of the second seal is shown as well as the first end portion of the second seal with a second housing 21, a second seal member 31 and a second actuation rod 41. This position is shown in FIG FIG. 1 labeled B.

The first actuating rod 40 has a second end which is the first in the FIGS. 5a to 5c opposite visible end. This second end may extend in the raised state within the seal housing. However, it may already protrude the housing 20. Preferably, this second end is at least then before the housing 20, when the first end is pressed in the direction of the housing 20 and the sealing element 30 is thus lowered. The same applies to the lowering seals described below.

The second end of this first actuating rod 40 has a concave sliding surface 400. The actuating rod 40 may be formed in one piece or it may consist of two or more individual parts, which are connected to each other over the length of the first seal extending coupling part. Preferably, the two ends are two individual parts which are fastened to the flat slide of the lowering mechanism. Preferably, they are fixed, e.g. bolted that the measure of their supernatant with respect to the housing 20 is adjustable. The actuating rods of the remaining seals are preferably identical in this regard.

The first end of the second actuating rod 41 preferably has a convex cam surface 410, which forms a counterpart to the concave crank surface 400. This second seal is attached to or in the first hinged door 13.

With the door closed 13, but open sliding gate, contact the two slide surfaces 400, 410 or they are slightly spaced from each other, as in FIG. 6a is shown.

However, when the double door 13 is closed and the sliding door is closed, the first actuating rod 40 presses, since it is present at the stop block 15 and thus pressed in by itself is, the second actuating rod 41 also in the second seal housing 21 into it. The second carrier rail is thereby lowered together with the second sealing element 31. This is in FIG. 6b represented, between the two actuating rods for better visibility a non-existent in reality gap is shown.

If the first wing door 13 is now opened when the basic wing 10 of the sliding gate is closed, the second actuating rod 41 pivots outward along the gate of the first actuating rod 40 and is released. The second seal rises again, so that the second sealing element 31 does not drag over the floor when opening and closing the first hinged door 13. When closing the first hinged door 13, the scenes allow 400, 410 thanks to a coupled pivoting and pushing movement again contacting the two actuating rods 40, 41 and thus pressing the second rod 41. The second seal is lowered again.

If the entire sliding gate, more precisely, the base wing 10, opened, the second end of the first actuating rod 40 also removes from the second seal and this is raised. When closing the basic wing 10, however, the second operating rod 41 is pressed in again due to the power transmission.

In the FIGS. 7a to 7c is the rear end portion of the second seal and the front portion of the third seal shown. This position is in FIG. 1 denoted by C.

The third seal is in turn arranged on or in the base wing 10. The rear second end of the second actuating rod 41 has a sliding surface, here in the form of an angled sliding plate 411. This sliding plate 411 is arranged with a first leg 412 perpendicular to the second actuating rod 41. A second, for the first angled leg 413 of the slide plate 411 protrudes laterally into the housing 20. Depending on the nature of the door or the arrangement of its pivot axis with respect to the closing direction of the gate, the second leg 413 of the door surface of the sliding gate projects outwards or it is integrated in the base or sliding door leaf. This also applies to the seals described below with sliding plates.

When opening the first hinged door 13 follows the sliding plate 411 according to this example, the door surface and thus the first leg 412 and is angled with respect to the door surface of the first hinged door 13 to the rear.

A first end of the third actuating rod 42 of the third seal is formed chamfered. Here, too, the second actuating rod 41 forwards the force in turn to the third actuating rod 42, so that the third seal is lowered accordingly. In FIG. 7b In turn, a distance between the bars 41, 42 drawn, which is not present in reality with lowered seal.

When opening the first hinged door 13, the sliding plate 411 slides along the inclined surface 420 and releases the third operating rod 42. The third seal also lifts. When closing the first hinged door 13, the second actuating rod 41 is pressed and forwards the force in turn to the third operating rod 42 on. The sliding surface 411 allows an optimal threading when closing the first hinged door 13th

The FIGS. 8a to 8c now show the situation between the basic wing area with third seal and the second wing door 14. This position is in FIG. 1 denoted by D.

Here, the rear second end of the third actuating rod 42 now has a sliding plate 421. This is the same as the first, i. among other things, with a first leg 422 and a second inclined leg 423. However, this oblique leg 423 is the second wing door 14 in the opening direction of this wing door 14 before or he is, as mentioned above, integrated into the surface of the door. Thus, this leg protrudes 423 on the other side of the base of the Schiebetors out as the second leg 413 of the slide plate 411 of the first hinged door thirteenth

Here now the fourth actuating rod 43 of the fourth seal is provided with an inclined surface 430. This inclined surface 430 is also inclined opposite than the previously mentioned inclined surface 420. This inclined surface 430 pivots when opening the second wing door 14 of the slide plate 421 along and presses when closing the hinged door 14 on the sliding plate 421, so that the fourth actuating rod 43 release accordingly or is pressed again.

In the FIGS. 9a to 9c the transition between the second wing door 14 and the third and rearmost portion of the base wing 10 is shown. This position is in FIG. 1 denoted by E.

The rear second end of the fourth actuating rod 43 in turn has a convex slide surface 431. The first front end of the fifth operating rod 44 is formed with a concave gate surface 440, the shape of which is suitable for use with the convex slide surface 431. The fifth actuating rod 44 is part of the fifth lowering seal, which is arranged on or in the third section of the base wing 10. The housing of the fifth seal is designated by the reference numeral 24. Here, too, takes place via the fourth actuating rod 43, the power transmission, so that the fifth lowering seal is activated. The in FIG. 9b drawn distance between the rods 43, 44 is in reality also not present at lowered seal.

In the FIGS. 10a to 10c Now is the fifth seal in the rearmost area of the sliding gate, ie in the rearmost area of the third basic wing section shown. This position is in FIG. 1 denoted by F.

There is no longer an operating rod here. There is thus no further power transmission.

The sealing unit according to the invention enables the flexible construction of a sliding gate with swell-free hinged doors, wherein all areas of the sliding gate can be provided with lowering seals. In this case, a single stop element is sufficient to obtain an optimal position for the seals for all positions of the sliding gate or the folding doors.
