EP2847410B1 - Lifting door assembly and door lintel sealing device therefor - Google Patents

Description

The present invention relates to a Hubtoranordnung, in particular a clean room door assembly, with a lifting gate, which has a door leaf, a cover plate and a Torblattaufnahmevorrichtung, and a Torsturz-sealing device which is provided in the region of a lintel so as to provide a sealing effect between the lifting gate and the Torschurz manufactures. Furthermore, the invention relates to a gate lintel sealing device for this according to claim 11 or 12.

Such Hubtoranordnungen are commonly used in industrial plants, such as workshops, warehouses or similar facilities application. In addition, due to the meanwhile achievable functionality, they are also intended for clean room applications.

For example, in clean room applications, such as in the pharmaceutical, medical and biotechnology, aerospace, electronics, automotive and precision engineering industries, rapid opening and closing to prevent air leakage, a smooth surface structure of the door panel for easy cleaning Deposits of particles and thus a low maintenance effort desirable. In addition, it is important to achieve a high density in the Hubtoranordnung and to keep the construction or installation depth, that is, the gate lintel height as small as possible.

With regard to the tightness, it is known to keep the clean room at overpressure with respect to adjacent zones in order to avoid a potentially polluted air flow from outside to inside into the clean room. Despite the pressure difference between the clean room and the adjacent zone can However, especially by a lintel of the Hubtoranordnung, leaks occur.

In the prior art, a sealing arrangement with a resilient deformation of a holding part and / or an elastic deformation of the sealing element itself has been repeatedly proposed to solve the leakage problem. This achieves a consistent tight contact of the sealing element on the door leaf.

So revealed the DE 93 14 823 U1 a roller shutter device for windows and doors. The sealing device shown here has support elements made of spring steel at the entrance to the gate lintel area, which hold a sealing roller and press against the given there roller shutter.

From the US 5,445,209 goes out a gate assembly with a brush seal, which naturally compensates dimensional changes, etc. by the elasticity of the bristles. The guide rollers shown there at the entrance slot in the lintel area, however, are only in the area of the lateral Behangränder.

The DE 36 03 417 A1 discloses a sealing device for roller blind boxes and, in some embodiments, also provides a sealing element in the form of brush seals or sealing profiles, which in turn perform elastic deformations to produce the sealing effect. In another embodiment, roller sealing elements are provided, but in which the sealing effect is not caused by spring element holders, but solely by gravity. In the process, these roller sealing elements rest on the door leaf.

Furthermore, the document discloses DE 60 2005 000 182 T2 a roller shutter with a sealing apron. This has a spring element designed as a sealing wing, such in the lintel area or in a Torblattaufnahmekasten is attached, that it supports itself by a prevailing overpressure with closed lift gate sealingly in the area of the coil to the curtain.

Sanding seals are also by the suspension strips on the roller shutter according to the DE 43 43 382 A1 known.

Finally, the reveals DE 39 21 036 A1 a sealing strip for lifting gates, which rests permanently on the here designed as a laminated armor door leaf. For this purpose, the sealing strip is so resiliently mounted around a notch or a resilient zone that they can dodge towards the gate lintel or spring back from this. In this way we achieved that the sealing strip in any position and in any direction of movement of the door leaf allows an adaptation to the respective distance of the door leaf from the lintel, so that distance variations between the frame box and the door leaf are compensated. Thus, the sealing strip is reliably against the outer surface of the door leaf and it is here a gap avoided.

These spring elasticity-based sealing devices have in common that they produce their sealing effect by constant contact with the door leaf, since this is grinding or rolling seals. However, this has the disadvantage that it comes to scratching and thus damage to the door leaf.

A slightly different configuration reveals that DE 199 06 628 A1 which to some extent provides for the provision of a one-sided movement gap between the curtain and the sealing device. This document discloses a Hubtoranordnung in the form of a Rauchschutzabschlusses with a lifting gate, which has a door curtain, a cover plate and a Torblattaufnahmevorrichtung, and with a Torsturz-sealing device, which is in the range of a lintel is provided so that it produces a certain - and in case of fire a complete - sealing effect between the lifting gate and the lintel.

This known lintel sealing device consists of a fixed part, namely a resilient run-off edge over which the door leaf is deflected towards the winding, and of an inflatable seal which lies opposite this run-off edge. In the normal case, this results in a one-sided movement gap between the curtain and this inflatable seal; in case of fire, this seal is supplied with compressed air, so that they then closes this gap and prevents the passage of smoke, etc.

However, since the door leaf is deflected here over the fixed part of this known lintel sealing device to the winding, it also comes to a scratching of the surface of the door leaf and thus to damage the same, which complicates in addition to a deteriorated appearance in particular the cleaning of the door leaf in the long run , As has been shown in the context of the present invention, it would therefore be advantageous to provide a free movement gap between the components of the lintel sealing device.

In addition, to keep a gate lintel height as low as possible and also to allow a smooth surface structure of the door leaf, the door leaf is designed in many Hubtoranordnungen as a flexible curtain with a cover plate. The curtain can be easily cleaned by particles fixed on it, and takes in a wound up in the lintel area in the lintel area little space. The end plate ensures the necessary stabilization of the curtain against external forces. To achieve maximum tightness of such systems, the gap from which the curtain comes out of the Torblatt- or Behangaufnahmekasten, kept as narrow as possible, ie, this movement gap just chosen so wide that the curtain can happen without significant friction losses.

This means, however, that the end plate, which typically has larger dimensions and in particular a greater thickness than the curtain or the lamellae, rests in a fully open position of the lift gate on a lower edge of the lintel or Torblattaufnahmekastens, creating a maximum available height of the door opening is reduced by the height of the closing lintel adjacent to the lintel.

This problem with regard to the limited use height of the door opening due to the protruding into this end plate is not addressed in the prior art. Only the documents DE 199 09 628 A1 and US 5,445,209 B reveal end signs. Most of the other prior art documents discussed above are roller blind assemblies, which typically have no end plates.

Also the closest state of the art DE 199 06 628 A1 offers no solution for this. Thus, the graduation plate is here admittedly in the area of the gate lintel in a receiving space; However, this is actually below the actual receiving device for the winding of the door leaf, so that there is no reduction in the gate lintel height or increase in the use height of the door opening.

The present invention is therefore based on the object to further develop a generic Hubtoranordnung such that this allows use of the substantially entire height of the door opening while maintaining the desired sealing effect.

This object is achieved by a Hubtoranordnung with the features of claim 1. This is characterized in particular by the fact that at least a part of the lintel sealing device held pivotally about a hinge is, and this is pivoted away by a actuator in the region of the end plate of a Torblattebene when opening the lift gate so that the end plate in the open state of the lift gate is substantially completely outside the range of a door opening can be arranged.

Due to the inventive pivotability of at least a portion of the gate lintel sealing device around the hinge serving as a hinge, it is thus possible for the first time to move the end shield into the lintel area when the lift gate is opened. The lintel sealing device is therefore no longer an obstacle in the range of motion of the end plate.

This can emerge from the area of the door opening, which has the advantage that in this way the entire passage height of the door opening can be used.

In addition, while the risk of damage to the lift gate can be reduced because a the entire gate opening height requiring object then no longer hits the end plate.

Advantageous developments of the Hubtoranordnung invention are the subject of the dependent claims 2 to 10.

Thus, the door leaf can be configured as a flexible curtain. Since such a wound up in the door leaf receiving device state occupies little space compared to, for example, a louvered door leaf, thereby the goal of reducing the lintel height and thus ensuring the maximum possible height of the door opening can be better taken into account. In addition, such a curtain is due to the ease of cleaning its smooth surface structure, as well as the clinical appearance, particularly well suited for clean room applications.

Furthermore, the end plate may have a greater thickness than the door leaf at least one point, wherein at least one shoulder of the end plate serves as an actuating device. This can be triggered by little design effort of the pivot mechanism of the lintel sealing device.

In one embodiment variant, the lintel sealing device may have a pivotable part and a non-pivoting part, wherein the pivotable part is preferably present on a door leaf inner side and the non-pivotable part preferably on a Torblattaußenseite. As a result, a particularly simple, compact and reliable construction for the Torsturz-sealing device is achieved. In particular, only a few parts must be moved in such an embodiment.

In a further embodiment variant, the lintel sealing device may have two pivotable parts, which, viewed from the side, lie opposite one another and receive the door leaf between them. By substantially parallel seal parts, the door leaf can be kept very stable and on a defined trajectory in the Torblattebene in the Hubtoranordnung. It is thus even better protected from external forces acting on the door leaf.

In another embodiment variant, the at least one part of the gate lintel sealing device can be formed from the hinge, which is mounted in the region of the lintel, and a round tube profile fastened thereto, which rests on the end plate in the open state of the lift gate. By such a design with round tube profile can be achieved an advantageous sealing effect. In addition, this embodiment has the advantage that due to the small gap of the guides of the door leaf, the resulting friction noise when opening and closing the Hubtors can be reduced.

In addition, two laterally axially mounted on the round tube profile plastic attachments can be provided in the camber-sealing device on the round tube profile of the lintel sealing device, whereby the noise can be reduced upon impact of the end shield on the lintel sealing device.

In a preferred embodiment, the plastic attachments are designed as rotatably mounted plastic rollers, whereby the frictional noise when opening and closing the Hubtors can be further reduced.

Further, additional plastic parts can be arranged on the end plate, which meet when opening the lifting gate on the gate lintel sealing device. Also by these plastic parts can be counteracted both an increased noise generation when opening and closing the Hubtors, as well as the wear desselbigen.

In a particularly preferred embodiment, the Hubtoranordnung is configured such that the additional plastic parts are arranged on the end plate so that they meet when opening the Hubtors on the plastic attachments or rollers of the Torsturz-sealing device. As a result, the friction noise when opening and closing the Hubtors can be reduced even more. In addition, the wear during operation or entrainment of the lintel sealing device can be further reduced.

According to two further aspects of the present invention, a gate lintel sealing device for a Hubtoranordnung according to the invention is provided according to claims 11 and 12 respectively. These gate lintel sealers can serve as a retrofit to existing Hubtoranordnungen and represent insofar an independently tradable unit.

Thus, the advantages explained above with reference to the lifting gate arrangement according to the invention can be achieved.

According to the representations in the Fig. 1a and 1b For example, in a first embodiment, a lift gate assembly 1A has a lift gate 2 with a door leaf 3, a closure plate 4 and a door leaf receiving device 5, and a lintel sealing device 20A.

The door leaf 3 is designed in the manner of a flexible curtain. Such hangings are particularly preferred in clean room applications because they have a smooth and thus easy to clean surface structure. In order to give the door leaf 3 or the curtain nevertheless a certain resistance to external forces acting, this is provided with the designed here as a rigid body graduation plate 4, which extends over the entire width of the curtain at the lower end. To counteract excessive noise and wear during opening and closing of the lifting door 2 in the area of the end plate 4, laterally additional plastic attachments 7 are arranged on the end plate 4, which meet when opening and closing the lifting gate on the gate lintel sealing device.

To guide the door leaf 3 and the end plate 4 are on both sides of a door opening O opposing guide or slide rails or the like (not shown). The Torblattaufnahmevorrichtung 5 is formed as a winding shaft and extends horizontally in the area of a lintel in the interior of a Zargenkastens 15. This defines here a lintel depth T and a lintel height H. Such a configuration is well known in the art.

Like from the Fig. 1a and 1b Furthermore, it can be seen, the end plate 4 has a greater thickness D than the door leaf 3. This is in particular due to the fact that the end plate 4 is dimensioned correspondingly large to achieve a sufficiently high stability, thereby to ensure the desired tightening of the door leaf 3.

It also goes out of the Fig. 1a and 1b the lintel sealing device 20A. This is defined in the area of the lintel on the inner walls of the frame box 15. The lintel sealing device 20A consists essentially of two parts, a pivotable part 10B and a non-pivotable part 10A. The pivotable part 10B lies on a door leaf inner side 3A and the non-pivotable part 10A on a door leaf outside 3B. The Torblattinnenseite 3A defines the cleanroom-facing side and the Torblattaußenseite the adjacent zone facing side. The pivotable part 10B and the non-pivotal part 10A form between them a small movement gap, in which the door leaf can move freely, ie, without Reibbeaufschlagung.

The pivotable part 10B is in this case articulated about a concealed hinge 9 and is seated in its rest position on an inner portion 8A of the Zargenkastens 15 so that it is only against the direction of gravity upward, ie, in the direction away from the door opening, pivotally. By the concealed arrangement of the hinge 9 is achieved protection against contamination, which z. B. from the wrapped curtain could fall down. In addition, this results in a relatively long pivot lever, which facilitates the operation of the pivotal part 10B and thus preserves the functionality in the long term. The non-pivotal part, the lintel sealing device 20A viewed from the side, is arranged higher than the pivotable part 10B.

If in the above illustrated Hubtoranordnung 1A now not shown system for pressurizing the clean room is activated, this has the effect that the door leaf 3 laterally displaced within the free movement gap and thereby against the slide rails (not shown) and in the area of the lintel is pressed against the non-pivotal part 10A of the lintel sealing device 20A and thus seals the clean room from the adjacent zone. The closed state of Hubtoranordnung is in Fig. 1a shown. The area of the lintel is defined by the Zargenkasten 15.

In Fig. 1b On the other hand, an actuating state of the lifting gate assembly 1A is shown, in which the lifting gate 2 is in a fully open position. As can be seen here engages a serving as an actuator shoulder of the end plate 4 in the course of the upward movement of the lifting gate 2 on the pivotal portion 10B of the Torsturz-sealing device 20A that this away from the Torblattebene and thus in the fall direction, ie, against the direction of gravity , is pivoted. In the open position of the lifting door 2, the pivotable part 10B of the lintel sealing device 20A bears against the side wall of the end plate 4. In this way, the end plate 4 and thus substantially the entire lifting gate can be moved into the frame box 15, which defines the lintel height H. As in Fig. 1b It can also be seen, in the area of the gate lintel, also in the open position of the lifting gate 2 a sealing effect, which prevents the penetration of dirt particles etc. in the Zargenkasten 15.

It should be noted that the pivotal portion 10B of the lintel sealing device 20A is not moved or pivoted by the door leaf 3 due to the given free movement gap, but only by attacking the contour of the end plate 4. In this way, a scratching or . Wear of the hanging surface reliably avoided. When closing the door leaf 3, the pivotal part 10B of the lintel sealing device 20A automatically pivots back into its rest position due to gravity and again forms the predetermined movement gap for the door leaf 3.

In the Fig. 2a and 2b is shown as a second embodiment, a Hubtoranordnung 1B. In order to avoid redundant parts of description, however, only the distinguishing features of the first embodiment will be explained in more detail below.

These can be found in particular in that here two pivotable parts 10C, 10D of a lintel sealing device 20B are given, which face each other with the formation of a free movement gap for the door leaf and are suitable for receiving the door leaf 3 between them. The two pivotable parts 10C, 10D are formed the same as the above-described pivotable part 10B and are located as in Figs Fig. 2a and 2b represented mirrored opposite.

Compared to the in the Fig. 1a and 1b illustrated embodiment, the Hubtoranordnung 1 B according to the Fig. 2a and 2b although a larger fall depth T 'on; However, the door leaf 3 is more advantageously positioned between the two pivotable parts 10C, 10D, since these are arranged here at the same height and the door leaf 3 thus safer and better guided between them take up. For receiving the end plate 4 in the frame box 15, the two pivotable parts 10C, 10D lead around the associated hinge 9 in each case a pivoting movement in the direction against gravity and away from the door opening.

In the Fig. 3a and 3b 2, a lifting gate assembly 1C according to a third embodiment is shown, in which a pivotable part 10E of the lintel sealing device 20C essentially consists of a hinge 14 which is mounted in the area of the lintel and a tubular section 12 attached thereto, which in the closed state of the lifting gate 2 is applied to the door leaf 3, is formed. More specifically, the hinge 14 is fixed with one side on an inner side of the frame 15, wherein the other side of the hinge 14 is pivotable with a round tube profile 12 fixed there at the end and, depending on the opening degree of the lifting gate 2, due to gravity on the end plate 4 or on an inner portion 8B of the Zargenkastens 15 on or rests.

In addition to the example designed as a rotatable round tube pipe profile 12 are, as in particular in the Fig. 5a and 5b represented, two laterally axially on the tube profile 12 by means of a bearing shaft 13 rotatably mounted plastic attachments 11 are provided which are formed as plastic rollers. These plastic attachments 11 are dimensioned such that they are present at least in the width of the plastic attachments 7 of the end plate 4, and meet when opening and closing the Hubtors 2 on this.

To accommodate the end plate 4, the tube profile 12 pivots about the hinge 14 in the direction against gravity and away from the door opening.

The in the Fig. 4a and 4b shown Hubtoranordnung 1D differs from that in the Fig. 3a and 3b Hubtoranordnung 1C shown, comparable like those in the Fig. 2a and 2b shown Hubtoranordnung 1B of the in the Fig. 1a and 1b shown in that two pivotable parts 10F, 10G of a lintel sealing device 20D are given, which face each other to form a free movement gap for the door leaf and are suitable to receive the door leaf 3 between them. The two pivotable parts 10F, 10G are formed the same as the above-described pivotable part 10E and are located as in Figs Fig. 4a and 4b represented mirrored opposite.

For receiving the end plate 4 in the frame box 15, the two pivotable parts 10F, 10G lead around the associated hinge 14 in each case a pivoting movement in the direction against gravity and away from the door opening.

The invention allows, in addition to the illustrated embodiments, further design approaches.

As an alternative to the described flexible curtain, the door leaf 3 can be designed, for example, as a lamellar armor, as a sectional door leaf or the like. In this case, instead of the winding shaft, for example, a spiral guide can be used as a Torblattaufnahmevorrichtung, which allows a non-contact winding of the door leaf.

In a further alternative embodiment, in which the door leaf 3 is not formed by a flexible curtain but, for example, by larger or thicker dimensioned fin sections, the thickness D of a cover plate may also be equal to or smaller than the thickness of the door leaf 3. Thus, the pivoting of the pivotable part 10B, etc. does not necessarily have to be initiated by the end plate 4. Alternatively, this can be done instead of the direct attack on the end plate 4 by means of an actuator happen, in addition to the end plate 4, preferably in the vicinity of this, is provided. The pivotable part 10B, etc. of the lintel sealing device 20A or 20B can thus be pivoted, for example, by means of alternative actuating devices such as other engagement elements, electrically controlled means or magnetic mechanisms, passively by entrainment or actively by a suitable control.

The shape of the end plate 4 is not limited to the shape shown in FIGS. The cross section of the end plate 4, which is typically an extruded profile can, depending on requirements by z. As a circular, elliptical, semi-circular, rectangular, triangular, symmetrical or asymmetrical profile can be replaced. In addition, the end plate 4 can also record a safety edge, not shown, for door safety.

The pivotal parts 10B, 10C and 10D, which are shown in the figures as identical or mirror-like components, depending on the application requirements may also have different shapes and thereby depending on the type of engagement or interaction function between them and the end plate 4 and the actuator accordingly be designed.

The in the Fig. 3a to 5b illustrated plastic attachments 11 are not limited to the embodiments described above. Alternative embodiments, such as polygonal, oval, etc. attachments of different (synthetic) compositions are conceivable. The same applies to the round tube section 12, which may alternatively be designed as polygonal, oval, etc. profile.

The Hubtoranordnung, which is shown above in particular for use in clean rooms, is of course not limited to this application, but can also be used as a room separation for any other systems, buildings, etc. serve. In particular, an application in the field of fire protection is possible to effectively prevent the passage of smoke, combustion gases, etc.

Furthermore, the lintel sealing devices 20A, 20B, 20C and / or 20D can also be retrofitted to existing lift gates 2 in order to make it fully usable in addition to achieving a desired sealing effect and the available height of the door opening O.
