Description

The present invention relates to a fire protection closure device according to the preamble of claim 1. The closure device may be formed as a roller door. Moreover, the invention relates to a suitable method according to the preamble of claim 13.

In other words, the invention further develops a closure device which comprises a material which can be wound onto a shaft and from which a wound state and an at least partially unwound state can be captured and which serves as a fire protection curtain. By a suitable method, a fire protection closure of a building opening can be formed by an arrangement of the windable material.

State of the art

A closure arrangement, which is intended to be suitable inter alia for an opening of a building, is in the utility model DE 20 2006 019 609 U1 (Owner: REHAU AG + Co., Date of registration: 30.04.2008). As a closure is a front blind, the at least one rotatably formed deflection by means of a transport element, according to FIG. 1 of the DE 20 2006 019 609 U1 a gear can be guided. The winding element should be arranged at a distance from the deflecting element. In the deflection element designed as a hollow shaft can be arranged to support an electric motor. However, the arrangement should essentially only prevent the incidence of light at a predetermined angle and thus are not suitable for closing an opening.

The utility model DE 295 21 561 U1 (Owner: Weinhuber, K .; Registration Date: 09.10.1997) provides a closing or separating device, wherein a fabric web can be wound up from both ends by means of two parallel rods provided with one pulling member each. If the device is in front of an opening, the opening can only be partially released.

A roller door is in the patent DE 42 27 328 C1 (Owner: Adolf Seuster GmbH; Date of issue: 07.10.1993). The roller door has a vertically standing pair of winding tubes, wherein a winding tube is in each case on one side of the door. In one embodiment, the winding tube pair of a separate engine on timing belt and diverter can be driven. Between the two parts of the door to be closed from two sides can still remain an at least partially permeable Ritz.

In the patent CH 503 884 (Owner: Griesser AG, publication date: 15.04.1971) a roller shutter is described, which is wound on two drive-connected, fixedly arranged to each other winding rollers. The smallest possible diameter of the rollers is limited by the hinged rods or lamellae that form the roller shutter. There are usually gaps between the bars or lamellae. In usual locking installations of shutters, z. B. in homes, it may be assumed that these spaces should allow an exchange of air between an interior and an exterior space. Due to the mobility of the bars or slats to each other, there is a risk that they jam each other when lowering the shutter and thus the shutter can not be fully unrolled.

A roller shutter in which the rollers are arranged adjustable or adjustable in the distance from each other, is in the patent and utility model application DE 1 849 457 (Applicant: WR Maas and RN Maas, date of publication: 05.04.1962) described The adjustability is to be realized by several bearing bores or adjustable in their distance bearing shells for receiving shaft journal.

One to CH 503 884 very similar embodiment of a roller shutter element is from the utility model DE 20 2011 052 483 U1 out. With a guide for the roller shutter on the roller shutter shafts slippage of the shutter on the shutter shaft should be prevented. Particular interest is given in the description of DE 20 2011 052 483 U1 a shaped body of heat-insulating material for receiving the roller shutter element.

In many known fire protection devices, such as. B. from the published patent application DE 10 2012 000 116 A1 (Applicant: BSM Brandschutz-Manufaktur Deutschland GmbH; Disclosure Date: 11.07.2013) shows, arranged a winding of a flexible protective element on a single winding shaft, which can be correspondingly voluminous.

The fire protection device according to the utility model DE 203 10 017 U1 (Owner: BS Brandschutztore GmbH & Co. KG, Date of registration: 04.11.2004) provides that the curtain is to be wound on a winding roll that can move in the vertical direction. The winding device comprises a belt shaft extending parallel to the winding shaft and fixed in the vertical direction. There may be disadvantages from the space requirement of the winding roll, because the entire winding roll must be lowered in or in front of a building opening.

The patent DE 698 31 044 T2 (Owner: AP Cooper, publication date: 07.04.1999) concerns a fire-retardant curtain. Each part of the curtain is to wind on a first and another part on a second role. Both parts of the curtain are combined at the end with an end bar. Already in an earlier patent application GB 2 108 839 A (Publication date: 25.05.1983) of the same applicant was in an embodiment according to FIG. 5 describes an arrangement of a fire protection curtain with a division, wherein the curtain parts are to be wound on different waves. By dividing the curtain is to be feared that in a connection area of the curtain parts leaks, z. B. by wrinkling, can arise.

Another two-reel concept is described in the international patent application WO 2010/142 944 A1 (Owner: COOPERS FIRE LIMITED, publication date: 16.12.2010). As FIG. 1 of the WO 2010/142 944 A1 shows a parallel arrangement of two waves, wherein a curtain is arranged in alternating segments on the first and on the second shaft, each with overlapping areas. A special mechanism keeps the waves at a suitable distance, depending on the winding condition of the curtain. A similar arrangement of two waves as in the WO 2010/142 944 A1 is in the publication EP 1 749 963 A2 (Applicant: D. Antoniazzi, Publication Date: 07.02.2007) has been used for awnings. Problems with the synchronization of the two waves can lead to drape in multi-part curtains, so that the curtain parts do not connect close together. It is to be feared that in the connection areas the closure remains incomplete.

The patent application US 2006/0151 132 A1 (Applicant: A. Scalfani et al., Disclosure date: 13.07.2006) relates to a hurricane protection curtain. The curtain includes, in one embodiment, first and second curtain rods. The second rod is provided to enhance stability. In addition, with the help of the second pole, the curtain material can be wound up firmer, so that the curtain fits under a decorative decorative strip. The curtain between the two rods or through the first rod should be pulled through. The two curtain rods may possibly be rotatable. The winding seems to be provided in the embodiments shown only on one of the rods. Wrapping is done by manual operation. The installation of the kit and the wrapping of the curtain may be a tedious task for some users.

From the publication DE 23 60 063 A1 (Applicant D. Rau, Disclosure Date: 05.06.1975) the use of a roller shutter box is known, which also has plastic parts in addition to metal parts, so that a heat or cold flow is interrupted via the shutter box.

Various aspects relating to structural fire protection, which also provide important information, in particular for the design of a closure, such as a roller shutter door, go, for. B. from the standards DIN EN 1634-1, DIN EN 1634-3 and DIN EN 13501-2 out.

task

In the construction or modernization of buildings, it has often been found in interested circles to be desirable to have a closure device for fire protection available, which occupies the smallest possible proportion of the interior of the building. In other words, an available for the installation of the shutter device space area better, especially efficient, be usable, so z. B. undesirable compromises for fire protection can be avoided if possible. According to a further aspect, the closure device is intended to enable a closure of a building opening associated with the closure device as quickly as possible, in particular reliably and reliably.

invention description

The object of the invention is achieved by a fire protection closure device according to claim 1; a suitable method for rolling up a windable material can be found in claim 13. Advantageous developments can be found in the dependent claims.

The closure device is intended for a building, in particular for an opening in or on a building. As a building z. B. buildings in which people or animals can stay. The closure device comprises a windable material, through which a closure can be formed. By an elastic flexibility of the windable material, a radius of curvature of the windable material is ingestible. The windability of the material makes it possible to make the closure device particularly space-saving. The closure may be formed by a curtain or by a roller blind, each comprising aufwickelbares material, z. B. when the opening a Window opening or a passage is. It is possible to provide the closure device as a roll-up door. A roller door serves to close an opening of a structure, such as a portal, as needed. In a roller door z. B. includes two leaves, a separate closure device may be present for each gate. Closure devices may be used for structures, such as listed buildings or special buildings, such as check-in halls at stations, ports or airports, z. B. for closing entrances, entrances, exits or passages are installed. It can also be said that a space divider can be formed by the closure device. Due to a small mass to be moved in comparison with a solid door, a closure device with material that can be wound up can be closed particularly quickly and can also be opened quickly. The closure device preferably provides protection against the propagation of flames, heat or smoke.

The closure device can be used particularly advantageously for a fire protection curtain. A fire safety curtain has a fire protection classification specified in relevant standards. In the case of suitable fire protection materials, there is often a need to use a larger material thickness of a fire protection curtain, so that a higher protective effect of the fire protection curtain is achieved. As a result, the closure device takes up a larger space. A fire protection closure device includes a fire protection curtain. The fire curtain is in a first state, the open state, rolled up. The windable material of the fire curtain is rolled up. The windable material is preferably storable in the open state for a plurality of years without deterioration of windability. In case of fire with a closure device, such as a fire protection closure device, a building opening as possible in a few seconds, such as less than 60 seconds, closed. A second state is a closure state. In the closed state, the windable material is spread. In an operating state of the closure device, at least a part of the windable material is conveyed through or over the building opening. It can also be said that the building opening is filled or hidden. According to a further aspect, the building opening can be released in an operating state.

Particularly advantageously, the device has at least one winding spreading, preferably an at least bidirectional winding spreading. The closure device comprises a rollable material. Of the windable material, a wound state and a developed state is ingestible. A first portion of the material may be in a wound state and a second portion of the material may be in a developed state. In the wound state, the windable material surrounds the Winding spread preferably at least two layers.

It can also be said that the winding spread predetermines or limits a winding core which deviates in a cross section along a width of the windable material from a circular shape. Thus, the shape of a wound state can be adapted particularly well to spatial requirements.

The closure device can be installed in a construction phase or subsequently as a kit in a building. It is Z. B. possible to accommodate the closure device at least partially in a suspended ceiling. The space between a building ceiling and a false ceiling is often cramped, z. B. because it has been built as space-saving or because other installations, such as cable harnesses or ventilation shafts, are above the suspended ceiling. A geometrically adjustable or geometrically adapted closure device can be used particularly advantageously. For the windable material of the closure device preferably a space-saving at least in a space dimension winding technique is used. Windable material may be in a wound state as a roll. From the role of the windable material is unwound. Material that has been unwound from a roll may also be referred to as a rollable material in a developed state. In other words, of the windable material two partial states are ingestible, wherein a part of the material is wound up and another part of the material is unwound. The two material states can merge into each other continuously, z. B. when coiled material is pulled onto the roll. In view of the presence of a single roll, a wound state may also be referred to as a rolled-up state. An unwound state starting from a single roll can also be referred to as an unrolled state. In the unwound state, the co-woveable material can be dispensed into an opening, wherein the opening is at least partially closable. The opening can z. B. be a ceiling opening of a building. The closure device is particularly suitable for openings in wall slopes. It is possible to make a partition with a closure device, wherein a first space in the building of a second space of the building, in particular for the prevention of health-impairing influences, in particular against influences due to a fire, is separable.

In one method, a coilable material of a closure device is rolled up. The windable material may also be referred to as a windable material. By rolling up a wound state is at least partially spent in a developed state. Material that is present as a role, can by gravity or by action a drive, which acts on an end portion of the windable material, be pulled out. In an unwound state, the windable material extends with respect to the building opening in such a way that a cover of the building opening can be formed. The windable material may extend into the building opening. An overall length of a windable material allows, for. As a curtain closure or a gate, which preferably extends over the entire building opening to form. In other words, the building opening is closed by windable material. During rolling up, at least part of the windable material can pass through a first deflection on a shaft and a second deflection on a winding spreading. The first deflection and the second deflection preferably follow a same direction of rotation. Like a spiral, the coiled material can together surround a shaft and the winding spreading. The wound material is piled up like a spiral. The arrangement is spiral. It can also be spoken of an arrangement as a spiral. The spiral is a deformed spiral. According to a further aspect, the material is wound in a space-saving manner, at least in one dimension, than in known closure devices.

In the following, advantageous embodiments and developments are set forth, which in themselves, both individually and in combination, can also disclose inventive aspects.

The closure device may comprise a shaft. The shaft can provide a winding core for windable material. In addition to a first shaft, at least one further shaft, such as the second shaft, may be provided. In addition to the shaft, a winding spreading is arranged. In one aspect, a winding spreading provides a winding corer extension for windable material. It can also be said that the winding spreading and the shaft together form a winding core which has been widened in at least one direction. With regard to the shaft, it can be said that the co-woveable material can be carried around a part of a circumference of the shaft. An analogous consideration applies to the winding spreading and in particular to possible further waves, such as a second or third wave. The winding spreading is arranged along the shaft. The winding spreading follows an orientation of the shaft, so that one can speak of a parallel arrangement. A parallel spacing is also present if the angular spread can be assigned as an aid to construction an axis which extends parallel to the shaft. In other words, the shaft and the winding spread at a predetermined distance from each other. Mutually associated end regions of the winding spreading and of the shaft can be arranged next to each other, wherein preferably a lateral end distance is the same. Preferably, a length of the shaft is greater than a winding width of the windable material. The winding spreading can be a plurality of Winding spreading segments include. Winding spreading segments may be spaced along a line.

In the wound state, the winding spreading and the shaft are wound together by aufwickelbarem material. The windable material may form an envelope about the winding span and the shaft along a longitudinal extent of the shaft. In the wound-up state, the windable material may preferably be multi-layered, such as at least two-ply. In the wound state, at least a first layer of the windable material is at the shaft and in the winding spreading. To the first layer can connect another wound layer, such as a second layer of the windable material. The first layer of the windable material may be in the wound state on a first side facing both the shaft and the winding spread. On a second side of the first layer is aufwickelbares material for forming the wound state can be stored.

The shafts may comprise a shaft material such as steel, light metal such as aluminum or brass, plastic, hardwood or a composite material. As a windable material is a non-flammable tissue.

Along the winding spreading and the shaft, a single arrangement of windable material is formed. The arrangement is spiral. It can also be spoken of an arrangement as a spiral. A spiral is a geometric shape resulting from a successive wrapping of a core through a sheet material. The spiral can be seen on a material edge along a longitudinal extension of the windable material, in particular when a view of a shaft end region is released. In other words, an extent of windable material as a single spiral means that not a first portion of the windable material exists as a first spiral and not a second portion of the windable material as a second spiral about a shaft. Connection or synchronization problems that might result from assembling parts of coilable material, each spiraling, do not occur because a single coil needs to be wound.

The windable material can be brought into a single roll via the winding spread and the shaft. The material can be stored as a roll. Of a spiral-like arrangement of the roll material is preferably a self-contained gate or a self-contained curtain can be formed. A provided for the role of the closure device space cross section in the building, can from a circular disk or from a square deviate and yet the space cross section can be filled efficiently. The weight of the windable material is distributed over at least one shaft and the winding spreading, so that in particular a few meters long role less sags. The material can be wound more evenly and is mechanically less stressed. The windable material is less stressed during winding.

It is possible to regard a shaft, in particular a shaft segmented in a longitudinal direction, as part of a winding spreading.

An advantageous embodiment of a closure device provides that the shaft is a first shaft and the winding spreading is a second wave. The waves can be the same length. Windable material can be brought into a single roll by the closure device. A roll comprises at least one layer of windable material. In an inner region of the roller, the first shaft and the second shaft extend. A roller cross-section formed by at least two shafts enables an improved filling of a limited space in the structure by the roller and an even more stability of the closure device.

The winding spreading may comprise a plurality of winding spreading segments. Winding spreading segments may be spaced along a line. A shaft may comprise a plurality of shaft segments, which preferably adjoin one another. This can, inter alia, reduce a total mass of the closure device. Installation work in a confined space of a building is facilitated.

The closure device may comprise a winding device. By winding device coiled material is einholbar. Coiled material can be carried out by the winding device in the building opening. The winding device comprises at least one shaft and preferably a drive device for the shaft. By the drive device rotation of the shaft is effected. A first shaft rotation may involve conveying co-woveable material in a first direction, e.g. B. out of the building opening, serve, the material is taken together as a role. A second shaft rotation opposite to the first direction of shaft rotation can convey material present as a roll into the building opening. Coiled material is in a hollow cylindrical arrangement around the shafts. The edge region of the material is present on side surfaces which can be geometrically assigned to a single cylinder outside a lateral surface, namely the base surface and the vertical surface. The width of the windable material may be referred to as cylinder height. In one of the widths assigned End of the material reveals the spiral-like structure of the role. The spiral can be a deformed spiral. A deformed spiral is preferably a spiral that has a constant winding distance, but whose core or evolute deviates from a circular symmetry. A constant winding distance is known from the mathematically idealized form of an Archimedean spiral emanating from a point. A deviation is considered to be a measure in comparison to a circular shape that is larger, preferably at least twice greater or four times larger than a thickness of the windable material. The spiral resembles the appearance of an involute. The thickness of the windable material preferably forms the winding spacing, so that the windable material in layers adjoins each other. An oval-like deformed spiral exists when a core is based on a cross-sectional structure, the z. B. has two mutually convexly oriented semicircles, which are connected by two, each on the circumference, in particular parallel, mutually arranged straight lines. The first semicircle may be associated with the shaft and the second semicircle with the winding spread. If the first semicircle has a smaller radius than the second semicircle, a trigonal-like deformed spiral can be formed. A trigonal deformed spiral may also be formed by using two or three shafts for the windable material. In a combination of multiple shafts, the windable material encloses the corrugations in roll form like a multi-sidedly deformed spiral. This is a shell shape of the role particularly favorable to an available space, the z. B. by a niche, in particular an angled niche, on a building support or a fall and a ceiling or a wall is given customizable.

There is an intermediate area between the winding spreading and the shaft. The intermediate area is a free space area. There is no coiled material in the intermediate area. On a first side of the intermediate area is the shaft. On a second side of the intermediate region, the winding spreading is arranged. The intermediate area between the winding spread and the shaft is at least so large that a shaft rotation is not hindered. By means of a rotation of the shaft and in particular of the winding spread, material that can be wound up can be brought to at least one further side which can be assigned to the intermediate region as a boundary. It can also be said that in a roll, at least two sides of the intermediate region are bounded by windable material. Due to the free intermediate region, an imaginary connection curve can be drawn from the winding spreading to the shaft in a region of the width of the windable material, without crossing any coiled material. The intermediate region is in an outer region of the shaft, wherein the shaft may be formed as a hollow shaft. The winding spreading can, in particular comb-like, extend in the intermediate region.

In the closure device, the shaft, preferably distance-resistant, installed opposite the winding spreading. The shafts are particularly well rotatable when they are each rotatably mounted on two pivot bearings. A first pivot bearing is assigned to the shaft. A second pivot bearing may be associated with the winding spreading. Between the first pivot bearing and the second pivot bearing, a holder, such as a support plate or a frame side plate extend, which determines the position of the pivot bearing to each other. The shaft is associated with a first axis of rotation extending inside the shaft. The winding spreading is associated with a second axis of rotation which extends in the interior of the winding spreading. An axis of rotation connects two first bearings and two second bearings. The shaft may be connected to winding spreading such that only an identical direction of rotation of the shaft about the first axis of rotation and the winding spreading around the second axis of rotation is possible. In other words, either the winding spread and the shaft rotate clockwise or counterclockwise. When using a plurality of waves preferably all waves have the same direction of rotation.

At least one of the shafts and / or the at least one winding spreading is or are connected to at least one motor. The motor can be a bearing of a shaft. The motor provides a bidirectional drive wherein a first direction causes a take-up rotation and a second direction causes an unwinding of the shaft. An electric motor drive is preferably carried out by a built-in shaft electric motor. The electric motor can be driven by a switchable current, in particular via a current regulator. By using electrical energy, a mechanical movement is effected. An electric motor allows a quick start of the shaft rotation and a rapid change of a direction of rotation, so that a wound state or an unwound state of the windable material is very quickly ingestible. Other embodiments have a motor as a motor or a hydraulic motor, especially if a corresponding pressure medium supply is present in the building. The engine can z. B. drive at least one pulley or at least one gear. It is possible to operate at least two motors with one, in particular electronic, rotational synchronization.

It is possible to provide an outer diameter of the shaft, which is different compared to an outer diameter of the winding spread. With the help of the selected outer diameter, the force to be applied during winding to the windable material can be dissipated particularly favorably on the bearings. Different outer diameters, such as a first outer diameter and a larger second outer diameter, in particular when using two or more shafts, can serve to form an advantageous roller geometry.

A rotation of the shaft and a rotation of the winding spreading can be synchronized particularly precisely to each other when a motor drive from the shaft to the winding spreading or vice versa, depending on the arrangement of the motor drive shaft or winding spreading, is transmitted. A rotation can be imparted via a drive belt. As an alternative, the winding spreading may comprise a motor drive. The drive belt is arranged so that it connects the shaft and the winding spread together. Preferably, the drive belt encloses the shaft and the winding spreading. The shaft can be composed of several waves. The drive belt can rest on at least one pulley, which is firmly connected to the shaft. An example of a drive belt is a flat belt. It is also possible on one or possibly on a plurality of shafts a circumferential, preferably stepped structured form, such as a groove shape having at least one recess to provide for the drive belt. This can increase a static friction. In a particularly space-saving embodiment, the drive belt can run in a depression on the shaft and in a depression on the winding spreading, in particular on a second shaft. Along a longitudinal extent of the shaft, a plurality of drive belts may be arranged, for. B. with a distance of at least ten inches (cm) between two drive belts. This results in a particularly uniform force distribution between the shaft and the winding spreading. The drive belt has a first, the waves facing surface. A second, facing away from the waves surface of the drive belt may form a support surface for the windable material. In other words, the drive belt may be a carrier for windable material. Preferably, the windable material surrounds the shaft and the winding spread at a distance. The distance may be predetermined by a thickness of the drive belt and a pulley or a gear circulation size. In this way, a frictional wear of the windable material, for. B. by dust or grains of sand, are kept as low as possible.

On a shaft, a plurality of gears may be arranged. As an alternative to gears, pulleys can be used. A gear, in particular a belt leads laterally, can also be referred to as a pulley. At least two gears are preferably along a longitudinal extent of the shaft. The gears on a shaft are at a fixed predetermined distance from each other. A winding spreading may comprise at least one gear. A gear or pulley may be rotatably mounted on a winding spreading segment. The arrangement may, for. B. chainsaw-like. A first gear on the shaft and a second gear, which is located on or on the winding spreading, form a group, wherein the gears are arranged spaced from each other. Between the grouped gears preferably extends circulating drive belt, such as a toothed belt or a revolving chain. A toothed belt has a particularly smooth surface for the support of the windable material. A drive belt, such as a toothed belt, preferably comprises an embedded tensile strand, which usually consists of glass or aramid fibers or steel cables. A tooth side of the toothed belt is preferably made of abrasion resistant fabric to protect the elastomeric teeth from wear. A drive belt, z. As a fiber reinforced plastic or a fiber reinforced rubber. A drive belt runs very quietly.

The windable material has at least one end portion extending along a longitudinal extent of the shaft. The end region can be connected to at least one toothed belt. In other words, a tensile force or a thrust force can be applied to the end portion of the windable material by the toothed belt. A first toothed belt can, for. B. parallel to a second toothed belt with a distance of at least 10 cm, preferably 1 m, be arranged. The timing belt has z. B. a width of 1 cm. The toothed belt has a toothing for engagement of the first gear and the second gear. The use of a chain is advantageous when the windable material has a particularly large weight. The chain is preferably made of steel. The gears are preferably circular. The gears on the shaft each have a matching first diameter. The first diameter is preferably a maximum diameter. The first diameter may also be a shaft diameter. The gears that belong to the winding spread, have a same second diameter. The second diameter is preferably a maximum diameter. The second diameter may also be a diameter of the second shaft. Preferably, a first maximum diameter and a second maximum diameter of the gears differ. Due to the selected gear diameter, among other things, a spiral deformation of the windable material in the wound state may deviate from the spiral around an oval spiral core.

The shaft and the winding spreading may be supported as a pair arrangement. A pair assembly is movable as a unit. If there are two or more waves, then a group arrangement can also be used in a similar sense. A possibility of movement of the pair arrangement is a pivoting movement. A pivoting movement is made possible by the fact that the pair arrangement about an axis, the z. B. along or extending through one of the existing waves, can be tilted. A rotatability of the pair arrangement is preferably limited by a fixed stop. This facilitates the assembly of the closure device. The pair arrangement can also be in be fixable a predetermined angle. The angle is z. B. in relation to an extent of aufwickelbarem material in the developed state can be fixed. It is also possible to provide that a mounted pair arrangement is rotatable by a predeterminable angle. A rotation angle can, for. B. 45 ° or 90 °. The Dr ehwinkel can also be referred to as a tilt angle, especially if no full rotation is executable. After adjusting the angle, the pair arrangement, z. B. on a holder, in particular on a frame side plate, fixed or locked. By the holder, the angular position of the pair arrangement is permanently preserved. The pair arrangement is z. B. adjustable from a horizontal position to a vertical position when a mounting location z. B. has under a building ceiling only one sufficient for a vertical position of the closure device mounting space.

According to another aspect, the winding spreading is in an angular position with respect to a mounting surface, for. B. on a building, similar to the previously described pair arrangement can be brought. This is particularly advantageous if the winding device or the winding spreading is free of waves. By adjustability of an angular position of the winding spreading a running plane of one or more toothed belts can be aligned. In other words, a running plane of the spiral-like arrangement of the fire protection curtain is tiltable to a desired position. A running plane is a plane in which the windable material, in particular in a deformed spiral, extends without deflection. A deformed spiral may also be referred to as a spiral stretched in a spatial direction, such as a first spatial direction. The deformed spiral has a smaller extent in a second spatial direction than in the first spatial direction. Here, the spiral is considered up to the line at which the windable material is at least two layers to each other. An extension difference resulting from a thickness of the windable material is disregarded. It can also be said that the pulled out fire curtain does not belong to the geometry of the spiral. The tilting can be done at the installation site. By tilting a first angular position can be converted into a second angular position. The winding spreading is adaptable to a holder, such as a tilting device, which allows tilting, in particular in a mounted state of the fire protection closure device, starting from a preassembled state, in particular to a desired angular position and preferably to a desired spread width.

A wave-free winding device is particularly advantageous together with heavyweight curtains, such as fire curtains used. Further advantageous fields of use are windable materials with surface rigidity, which in particular is greater than in the case of a PVC household film, or a material thickness of more than 0.3 cm (cm) of the windable material.

In a space-saving arrangement, a windable material, which is provided as a fire protection curtain, preferably at least partially stacked without gaps. A space-saving arrangement forms z. B. in a parallelepiped void volume with three unequal side lengths a smaller clearance than in a cuboid volume with the same first and second side length, wherein a third side length is arranged in each case along a width of the windable material. The side lengths are generally assignable to each room dimension. At least one dimension, in particular according to one aspect of mobility, is a preferred direction in space. The angular position may be an orientation of the wound material relative to the first or relative to the second side length or side of the void volume, in particular if the void volume more than six side surfaces are assigned. The term space-saving deformation may mean, among other things, that when taking the arrangement in the circulation of the winding spreading takes place, in particular elastic, deformation of the windable material. One possibility of the deformation is an extension of a surface, wherein the stretch is in a deflection region of the wound material, in particular gradually through a material thickness.

Advantageously, spreading struts, such as pipe segments, the z. B. are composed of at least two mutually fixable strut parts present in a winding spread. A position or length of partial struts is advantageously adaptable to each other on a longitudinal axis. To facilitate tilting, an abutment, in particular with a radial angular graduation, and a locking device may be present. The abutment or the locking device can each be attached to the frame or on the stabilizing strut or on the spreading strut. The locking device sets an angular position of the winding spread at least for the operating life of the winding device. A selected angle of the winding spread is z. B. fixed relative to a frame. This allows a particularly precise adaptation of the winding spreading to a space.

The winding core can with respect to its position in space, for. In relation to an axis formed by a perpendicular as a reference. An extension of the winding core in at least one direction can be adjusted. From the aspect that the winding core is not defined by a single filling or space-limiting solid state shape, the winding core may also be referred to as a space or a free volume located in a core area of a roll or a roll of the windable material.

In a particularly advantageous embodiment of a fire protection closure, a winding spreading may comprise at least one stabilizing strut and at least two, preferably at least four, spreading struts. A stabilizing strut may be part of the winding spreading. Among other things, the stabilizing strut serves to counteract sagging of elastic, windable material, in particular in a wound state, such as a roll. An elastic material may, for. B. form a wave or loop-like fold under the action of a narrow-side thrust, which can smooth itself again without the thrust in particular. Supported by the stabilization strut, the fire protection curtain remains as smooth as possible over the width of the curtain.

At least one stabilizing strut or at least one of the spreading struts can support a drive device, such as a motor, in particular an electric motor, or a drive wheel, which serves to drive the windable material. The winding spreading may include, among other things, a toothed belt, an impeller or a pulley or a gear, which may be present individually or in plurality for supporting the windable material or as components of the winding device for conveying the windable material. For conveying the windable material, the winding device has rotatable components. The winding device may comprise the winding spreading. To support or for transport ball bearings or plain bearings can be attached to the winding spreading, in particular on the spreading struts or support struts. At least one of the pivot bearings may be formed by a motor. Thus, the fire curtain is particularly smooth running and can be opened or closed faster than known closure devices. In addition, rollers on lateral edge areas of the fire curtain can further improve the running behavior of the curtain in lateral guide rails. At least one roller is preferably mounted in a guide region of a guide rail.

A longitudinal extent of the shaft of the closure device may, for. B. up to 6 m and more. It is possible, as already described above, to reinforce the closure device by at least one stabilizing strut. A bending or sagging of the shaft is avoided by means of stabilizing strut. The stabilizing strut is in one aspect a stiffener of the closure device. The intermediate area along the shaft is available for housing a stabilizer. The stabilizing device may comprise at least one stabilizing strut. The stabilizing strut preferably extends along the shaft. Particularly stable is a stabilizing strut, as a trapezoidal profile rod, U-profile rod or as a hollow profile rod is trained. The stabilizing device may be connected to the winding spreading. According to another aspect, the stabilizing device may comprise at least one shaft support element. The shaft support element is attached to the stabilizing strut. The first shaft and / or a further shaft extend transversely to the shaft support element. A friction-reducing coating, such as a plastic coating, can be applied to the winding spreading, the stabilizing strut and / or the shaft support element. A particularly good support provides a stabilizing strut, which is attached to a support plate. The support plates extend at the end portions of the shaft. Preferably, a first support plate and a second support plate are provided, which is associated with the respective first and second ends, if a plurality of shafts is provided. The stabilizing strut may be welded to the support plate. It is also possible to attach the stabilizer strut to the support plate with a stabilizer strut mount. An attachment is z. B. by a screw, a rivet or a connector possible. The stabilizer may be present as a diagonal strut in the intermediate region. The diagonal strut forms an angle to the shaft. The stabilizing device may also be provided as a cross stabilizer. A cross stabilization has at least four stabilizing struts, which are each fastened to a support plate and have a common connection region. Cross stabilization is particularly advantageous when the shaft and the winding spreading or another wave a distance of more than 20 cm, z. B. more than 50 cm or more than 100 cm from each other.

Particularly robust is a closure device in which the shaft and the winding spreading are mounted in a common frame. The frame can z. B. be a cuboid structure having a hollow profile bar at a plurality of edge regions. To protect against contamination preferably the shaft and the winding spreading and the windable material are housed in the wound state in a housing. The frame may be part of the housing. Side surfaces may be at least partially enclosed by the frame. A temperature gradient can lead to the formation of stresses in a rigid material, such as a frame structure or a housing, whose distortion is to be avoided as far as possible for operational safety of the closure device. Preferably, at least one side surface of the closure device is covered with an elastic material and / or with a film. A temperature gradient of the substance or the film does not stress the closure device. Effects of a temperature gradient across the frame on the waves and in particular a rotation of the waves remain as low as possible. In addition, the windable material is protected from dust and other contaminants. An even better protection, z. B. against the spread of Smoke particles, provide a fabric and / or a sheet material, such as a fiber-reinforced film, which are suitable for fire protection. The weight of the closure device is kept as low as possible by using fabric and foil, which among other things facilitates installation.

The winding spreading can be arranged on at least one stabilizing strut. The stabilizing strut is, for. B. via a frame, attachable to a building. The stabilizing strut is arranged in the intermediate region, which is in particular a partial region of the winding core. From the stabilizing strut, a series of spreading struts may extend in a first spreading direction. At least a second series of spreading struts may be attached to the (first) stabilizing strut or to a second stabilizing strut. The second sequence extends in a second spreading direction. The first sequence of spreading struts and the second sequence of spreading struts are preferably arranged at an angle of more than 30 ° to each other.

At one end remote from the stabilizing strut end of the spreading strut, a gear or a pulley can be rotatably arranged. A first expansion strut and a second expansion strut and possibly further expansion struts are aligned with each other such that a plurality of gears or a plurality of pulleys with an annular drive belt for torque transmission can be connected. In a first aspect, the drive belt carries the windable material. According to a further aspect, the windable material is conveyable around the winding spreading around by the drive belt.

For the transport of the windable material, preferably by at least one motor, a tensile force can be applied to at least one drive belt. The tensile force acts along the windable material.

The windable material is variable in length over or through a building opening.

For fire protection z. As an aramid material as a film or as a fabric. It is also possible to use glass fiber fabric. Particularly advantageous is a layer material in which materials such as films or fabrics are combined with each other in order to combine their specific advantages, such as a high heat insulation, high density and low erosion, with each other. The windable material is preferably a non-combustible material. One possibility for a non-combustible material is a fire-resistant fabric in which heat and fire resistant fibers are interwoven. It is possible to use an open-mesh fabric, such as a glass fiber fabric having an intumescent coating. In one embodiment, the fibers may stick through the coating at a temperature of 100 ° C. At a temperature of 150 ° C, pores of the tissue are closed. At a temperature of 200 ° C foaming of the coating takes place. On the fire protection fabric, an insulating layer, such as an insulating foam is formed, which acts as a heat brake. A fire protection film is preferably reinforced by drawn into the film wires or fibers to better withstand mechanical stress. Even more stable is a rollable material having a first layer and a second layer. Preferably, the first layer and the second layer completely overlap each other. A windable material may have a layer thickness of less than 0.5 mm. A better fire protection is achieved by a greater layer thickness than 0.5 mm. Good protection offers z. B. a total layer thickness of a, preferably multi-layer, windable material of at least 4 mm. With a layer thickness between 10 mm and 20 mm, a particularly good fire protection with good windability and durability against mechanical stress can be realized. As a windable material layer thicknesses of up to 30 mm, preferably less than 100 mm, usable. This makes it possible to provide a particularly long resistance to fire in the event of a fire. The closure device is suitable for newly constructed structures as well as for historical buildings. By the closure device is at building openings a particularly large opening cross-section z. B. for a passage, because the closure device considered itself is very compact. It is also possible to integrate the closure device in a wound state more harmonious in the architectural structure of the building.

The previously described combinations and exemplary embodiments can also be considered in numerous other connections and combinations.

figure description

The in the FIGS. 1 to 9 Illustrations shown embodiments of the closure device 2, 102, 202, 302 and 402 have many similarities, which are explained to avoid repetition only on individual embodiments or figures. For corresponding object features, the respective numerical values are reserved with a distinction in steps of "100".

The closure device 2 in FIG. 1 relates to a roll-up door 4. The roller shutter 4 is mounted in a ceiling area 9 of a building 8 and serves to close a building opening 11. The closure device 2 has a frame 80 which is fastened to the ceiling area 9 with the frame attachment 82. On the frame 80 is a string support 88, on which a cover fabric 89 for a first side surface 85 of the frame 80 can be pulled. The cover fabric 89, dashed in FIG. 1 registered, may also cover a second side surface 86 to the sealing rail 92 out. An insulation board 12 provides a warming protection for the closure device 2 on another side surface (without reference numerals). The cross-sectional view of FIG. 1 reveals the view of a first side plate 81 attached to the frame 80. A second side plate (not shown) configured correspondingly to the first side plate 81 protrudes from the first side plate 81 on the frame 80. On the first side plate 81 a support bracket 78 on slots, such as the slot 79, slidably mounted. The support bracket 78 carries a first rotary bearing 48 a winding spreading 30, which in the execution of FIGS. 1 and 2 is designed as a wave. Another first pivot bearing (in the sectional drawing of FIG. 1 Not shown) makes it possible that the winding spreading or shaft 30 is rotatable about a first axis of rotation 51. The winding spreading 30 has an outer diameter 33, on which a first gear 56 is fixed with a first gear diameter 57, wherein a Zahnradmitnehmer 62, such as a welding point, a connection between the first gear 56 and the shaft 30 secures against rotation. Under the shaft 30, the sealing rail 92 extends in parallel through which among other things the stability of the frame 80 is increased. On the first gears, such as the gear 56, there is an annular drive belt, such as the drive belt 64. The drive belt 64 has a circumferentially continuous teeth, such as the tooth 65, which faces the gear 56. The drive belt 64 provides a bearing surface 68 for windable material, which can be mounted at an attachment point 67. A shaft 32 is provided, which is driven by an electric motor 54. Thus, the shaft 32 may be referred to as a first shaft. A shaft cam 55 transmits a driving force from the electric motor 54 to the shaft 32 by means of the shaft cam 55. The motor 54 provides a second pivot bearing 49 which allows rotation of the shaft 32 about a second axis of rotation 52. By the rotation of the shaft 32 by means of electric motor 54, a second gear 58 drives the drive belt 64 at. The drive belt 64 offset via the first gear 56, the winding spreading 30 and shaft 30 in rotation. The shaft 30 has a first outer diameter 33 which is equal to the outer diameter 31 of the driven shaft 32. The second gear 58 has a second gear diameter 59, which is greater than the first gear diameter 57 of the first gear 56 on the winding spread 30. The first gear 56 and the second gear 58 form a first gear group 60, over which the drive belt 64 extends. Parallel to the first gear group 60 further gear groups (not shown), in particular a second gear group, which is configured equal to the first gear group and is covered with a drive belt, be installed. The elongated holes, such as the slot 79, on the support bracket 78 serve to adjust the shaft spacing 34 between the first axis of rotation 51 and the set by the drive support 76, the second axis of rotation 52 so that the drive belt 64 clamped on the gears 56, 58 rests.

In the cross-sectional representation of FIG. 2 is a aufwickelbares material 13 shown in the form of a roller shutter 4 closure device 2. There is a roller 19 in the closure device 2 before. An end portion 14 of the windable roll-up material 13 is mounted to the attachment point 67 on the drive belt 64. On the drive belt 64, the support surface 68 of the windable material 13 is formed. The windable material 13 is located as a spiral 20 to the drive belt 64. The roller 19, which can also be referred to as a winding, with the spiral-like arrangement 20 is located on the winding device 7. In the cross-sectional view of FIG. 2 is the edge portion 22 of the windable material 13 hidden. The windable material 13 surrounds the shafts 30, 32. The windable material 13 surrounds the gears 56, 58. Between the shafts 30, 32 there is an intermediate portion 42 which on a first side 43 through the shaft 30 and on a second side 44th is left open by the shaft 32. On a third side 45 and a fourth side 46, the intermediate region 42 is bounded by the drive belt 64 and by the windable material 13. At the outlet opening 95 of the winding device 7, the windable material 13 is in a developed state 17 before. The windable material 13 has a first layer 23 and a second layer 24 which are fixedly connected to each other. A total layer thickness 27 of the windable material is 10 mm. Starting from a wound state 16, the unwound state 17 can be dispensed through the outlet opening 95, as a result of which the roller shutter 4 can form a closure (not shown).

In the cross-sectional view of a closure device 102 in FIG. 3 was, as in FIG. 1 , For the sake of clarity aufwickelbares material 113 omitted. In FIG. 4 is similar to FIG. 2 10, the windable material 113 provided for a fire barrier 106 of the closure device 102 is shown. The closure device 102 has a frame 180 and is mounted in a ceiling region 109 of a structure 108 by means of a frame attachment 182 over a building opening 111. Along the building opening 111 extends a guide rail 190, which opens into the outlet opening 195 of the closure device 102 with a receiving area 197 which is assigned to the frame 180. The guide rail 190 serves as shown in FIG FIG. 4 is shown, a lateral guide of an edge of the windable material 113. The closure device 102 in FIG. 3 comprises a shaft 132 and a winding spread 130, on which a first gear 156 and a second gear 158 are rotatable by means of toothed belt 164 in a direction of rotation 15 in the same direction. The gears 156, 158 are drawn transparently to make the underlying arrangements more visible. The winding spreading 130 is segmented along the shaft 132, in other words, not wave-like continuous. The individual winding spreading segments are connected to the stabilizing strut 170 or to the frame 180. A clockwise direction of rotation 153 is indicated by arrows by way of example. In FIG. 3 Corresponds to a clockwise rotation of a wind-up rotation exerted on the shaft 132 by an electric motor 154 to create a wound state such as the wound state 116 in FIG FIG. 4 , A particularly good load-bearing capacity of the winding spread 130 is obtained by a toothing of the support leg 178 of the winding spread 130 with a further support leg 178 '. The suspending support is associated with the winding spreading 130. By the direction of rotation 153 exerted forces on the winding spread 130 are at least partially derived on the support brackets 178, 178 'to the frame 180. A drive support 176 associated with the electric motor 154 has elongated holes, such as the slot 177. The shaft 132 is slidable with respect to the winding spread 130 in order to tension the toothed belt 164 can. In an intermediate region 142, the stabilizing strut 170, which is connected to the frame 180 via a stabilizing strut mount 174, extends. The intermediate region 142 extends around the stabilizing strut 170 from a first side 143 on which the shaft 132 is located to a second side 144 where the winding spreading 130 is located. The stabilizer strut 170 releases the intermediate portion 142, which is opposite to the timing belt 164, so far that the teeth, such as the tooth 165, can be guided along the stabilizer strut 170.

In FIG. 4 is the intermediate region 142 on the other sides 145, 146 bounded by the windable material 113. The toothed belt 164 serves to form a bearing surface 168 with the windable material 113. Windable material 113 is present as a roller 119. By a rotation of the electric motor 154 in the direction of rotation 153 'in the counterclockwise direction, the shaft 132 and the toothed belt 164, the winding spreading 130 in the same direction of rotation 153' driven. The windable material 113, which is in the unwound state 117, can be lowered into the guide rail 190 with the end region 114 ', which can also be referred to as the closure end region 114'. Thus, the building opening 111 can be closed. At the end portion 114 'is a sealing body 121 which serves to attach the fire curtain 106 to a floor area (not shown). When unwinding in the direction of rotation 153 ', the attachment point 167 runs on an end region 114 of the windable material 113, which can also be referred to as the winding end region 114, around the winding spread 130 and around the shaft 132. In a time sequence of a toothed belt movement, a distance of the attachment point 167 to the winding spread 130 can be increased periodically and reduced again. As the windable material 113 unwinds, the intermediate region 142 remains free of co-woveable material 113. The windable material 113 includes a first layer 123 and a second layer 124 having a swellable interlayer 125 therebetween. In an unwound state 117 which can be created for a closure (not shown) of the building opening 111, an adequate sealing against the passage of smoke can be achieved by means of a swelling tape 193 which is glued onto the sealing rail 192 with sufficient heat development. Another sealing rail 192 'with a swelling tape (not shown) on the in FIG. 3 designated outlet opening 195, the seal against the windable material 113 in the closure device 102 of FIG. 4 even better.

FIG. 5 and FIG. 6 show a further embodiment of a closure device 202 for a fire curtain 206. An optionally, for. As in a fire alarm, to be closed building opening 211 is located under a wall portion 210 of a building 208th

In the embodiment of the Figures 5 and 6 In comparison with the other embodiments, driven and guided shafts or winding spreads are exchanged, to clarify that the invention is independent of the positioning of active and passive shaft or active and passive winding spreading.

The closure device 202 is bolted to the wall portion 210 with the frame mount 282 for a frame 280. The frame 280 is connected to a guide rail 290 for windable material 213. The frame 280 includes two side plates, such as the side plate 281. On the first side plate 281, a first support plate 272 is rotatably mounted about an axis 236. A first shaft 232 and a second shaft 230 extend from the first support plate 272 as a pair assembly 235. The shafts 230, 232 are each in common in a same direction of rotation, which in the Figures 3 and 4 is shown by the electric motor 254 in FIG. 5 rotatable, in particular rotatable. A rotational movement of the shafts 230, 232, which may also be referred to as shaft rotation, is mediated by a toothed belt 264. By lowering windable material 213, a roller 219 is reducible. The roller 219, also referred to as a winding, is located on the winding device 207, wherein a bearing surface 268 is present between the toothed belt, such as the toothed belt 264, and the windable material 213 of the roller 219. The winding device 207 comprises, as a pair arrangement 235, the first shaft 232 and the second shaft 230, between which there is an intermediate region 242. Between the winding device 207 and the guide rail 290, in particular with respect to the support plates of the winding device 207, as the first support plate 272, there is a variable angle 239. The angle 239 can also between the building 208 and the wall portion 210 and an imaginary, axial connecting line between the shafts 230, 232 are located. By a rotation 238 about the axis 236, the shaft 230 of the pair assembly 235 is approachable to the wall portion 210. For example, during assembly, an adjustment of the winding device 207 is possible. The timing belt 264 is adjustable to extend in a straight area in a direction of the guide rail 290. The angle 239 may, for. B. 90 °, without the building opening 2 11 is narrowed by the winding device 207. It is an angle, such as the angle 239, ingestible, which is preferably greater than 0 ° and in particular less than 180 °.

In FIG. 6 the closure device 202 is shown with a position of the winding device 207 in which a relative to the angle 239 in FIG. 5 enlarged angle 239 'is taken. By a rotation 238, 238 'of the winding device 207 in FIG. 6 , which can also be referred to as tilting 238, 238 ', the angle 239, 239' in a selectable, fixed end position changeable. Each of a support plate, such as the first support plate 272, associated edge portion, such as the edge portion 222 of the roller 219 of the windable material 213 is present as a spiral 220. The guide rail 290 assigns a predetermined direction to the edge portion 222 continued from a wound state 216 to the unwound state 217. When turning 238 'in FIG. 6 as well as the rotation 238 in FIG. 5 the frame 280 and the side plate 281 remain fixed to the wall portion 210. As in FIG FIG. 6 can be seen, the winding device 207 is positionable by rotation 238 for resting on the wall portion 210. The angle 239 'in FIG. 6 locates the roller 219 closer to the wall portion 210 than the angle 239 in FIG FIG. 5 , In this way, the closure device 202 can be placed on the wall region 210 with as small a stem as possible. A space segment located above the side plate 281 in front of the wall region 210 can be filled by the closure device 202. An aesthetically undesirable niche over the closure device is not lost completely as a cavity to be faded off.

The fastening elements 382, 382 'are provided for ceiling mounting of the closure device 302. In one Intermediate portion 342 between the first shaft 332 and the second shaft 330, a stabilizing strut 370 is installed. The stabilizing strut 370 has a trapezoidal hollow profile open on one side in cross section. Stabilizing strut 370 is secured to support plates, such as first support plate 372, by screws (not numbered). The second shaft 330 is guided by a shaft support member 371 fixed to the stabilizer strut 370. Parallel to the second shaft 330, the sealing rail 392 extends. The sealing rail 392 has a trapezoidal, unilaterally open hollow profile in cross section. The sealing rail 392 is fixed to side plates such as the first side plate 381. Surrounding the sealing rail 392 are insulating boards such as the insulating board 312 'and the insulating board 312 ". The insulating boards 312', 312" serve to heat-insulate the sealing rail 392, so that the sealing rail can be used in case of increased ambient heat of e.g. B. 100 ° C as possible retains its shape.

There is a first adjustment of the winding device 307, which serves to tension the drive belt 364, which surrounds the shafts 330, 332. On the winding device 307 aufwickelbares material 313 is placed in a wound state 316 as a roller 319. From the roll 319, coiled-up material 313 hangs down in a developed state 317 so far that coiled-up material 313 is located in the guide rail 390. The guide rail 390 extends along the building opening 311, which can be closed by the application of the windable material 313 in the unwound state 317, in other words, by the fire curtain 306.
