Description

The present invention relates to a closure device according to the preamble of claim 1. The closure device can be designed as a roller door. The closure device is preferably suitable as a fire protection curtain. The invention also relates to a suitable method according to the preamble of claim 31.

In other words, the invention further develops a closure device which comprises a material that can be wound onto a shaft, from which a wound state and an at least partially unwound state can be taken. Using a method according to the invention, a closure of a building opening can be formed by an arrangement of the windable material.

State of the art

A closure arrangement that is intended to be suitable, among other things, for an opening in a building is described in the utility model DE 20 2006 019 609 U1 (Owner: REHAU AG + Co.; entry date: April 30, 2008). A front blind serves as a closure, which has at least one rotatable deflection element with the aid of a transport element, which according to 1 the DE 20 2006 019 609 U1 can be a gear, is guided. The winding element should be arranged at a distance from the deflection element. An electric motor can be arranged to provide support in the deflection element designed as a hollow shaft. However, the arrangement should essentially only prevent light from entering at a predetermined angle and is therefore not suitable for closing an opening.

The utility model DE 295 21 561 U1 (Owner: Weinhuber, K.; date of entry: October 9, 1997) provides a closing or separating device, whereby a fabric web can be wound up from both ends using two parallel rods, each with a tension element. If the device is in front of an opening, the opening can only be partially opened.

A roller shutter is in the patent DE 42 27 328 C1 (Owner: Adolf Seuster GmbH; date of issue: October 7, 1993). The roller door has a vertical pair of winding tubes, with one winding tube standing on one side of the door. In one embodiment, the pair of winding tubes should be able to be driven by a separate motor via a toothed belt and deflection gear. An at least partially permeable crack can still remain between the two parts of the gate that is to be closed from two sides.

In many known fire protection devices, such as. B. from the disclosure document DE 10 2012 000 116 A1 (Applicant: BSM Brandschutz-Manufaktur Deutschland GmbH; disclosure date: July 11, 2013) shows that a winding of a flexible protective element is arranged on a single winding shaft, which can be correspondingly voluminous.

The fire protection device according to the utility model specification DE 203 10 017 U1 (Owner: BS Brandschutztore GmbH & Co. KG; entry date: November 4th, 2004) stipulates that the curtain must be wound up on a winding roll that can be moved in the vertical direction. The winding device comprises a belt shaft which extends parallel to the winding shaft and is fixedly arranged in the vertical direction. Disadvantages can arise from the space required by the winding roll because the entire winding roll has to be lowered into or in front of a building opening.

The patent specification DE 698 31 044 T2 (Owner: AP Cooper; Publication date: April 7, 1999) concerns a fire-retardant curtain. One part of the curtain must be wound onto a first roll and another part onto a second roll. Both parts of the curtain are connected at the end with an end strip.

Fire protection screens or curtains according to the British patent application GB 2 108 839 A (Applicant: AP Cooper; Filing date: October 13, 1982) are similar to those in the DE 698 31 044 T2 to wind onto a single shaft. The embodiment of 5 the GB 2 108 839 A accordingly shows a two-shaft arrangement, with two curtain parts of a longitudinally divided curtain being able to be wound onto a first roll and a middle part onto a second roll. The middle part is intended to create a passageway. According to 5 It can be assumed that the rollers are arranged in a fixed manner one above the other, which means that the overall space required for the curtain is likely to be increased compared to a single curtain on a single shaft. The standard suitability of such a curtain for fire protection is based on the GB 2 108 839 A not prominent.

Another two-role concept is used in the international patent application WO 2010/142 944 A1 (Owner: COOPERS FIRE LIMITED; publication date: December 16, 2010). How 1 the WO 2010/142 944 A1 shows, there is a parallel arrangement of two shafts, with a curtain being arranged in alternating segments on the first and second shafts, each with overlap areas. Through a special mechanism, the waves, each after the curtain is wound, kept at a suitable distance. A similar arrangement of two waves as in the WO 2010/142 944 A1 is in print EP 1 749 963 A2 (Applicant: D. Antoniazzi; publication date: February 7, 2007) has been used for awnings. Problems with the synchronization of the two shafts can lead to folds in multi-part curtains, so that the curtain parts do not fit tightly together. It is to be feared that the closure will remain incomplete in the connection areas.

The patent application US 2006/0 151 132 A1 (Applicant: A. Scalfani et al.; Disclosure date: July 13, 2006) concerns a hurricane protection curtain. In one embodiment, the curtain comprises a first and a second curtain rod. The second rod is provided to improve stability. In addition, the second rod should allow the curtain material to be wound more tightly so that the curtain fits under a decorative decorative strip. The curtain should be able to be pulled through between the two rods or through the first rod. The two curtain rods can possibly be rotatable. Winding appears to be provided on only one of the rods in the embodiments shown. Winding is done manually. Some users may find assembling the installation kit and winding the curtain tedious.

From the disclosure document DE 23 60 063 A1 (Applicant D. Rau; disclosure date: June 5, 1975) the use of a roller shutter box is known which, in addition to metal parts, also has plastic parts so that a flow of heat or cold via the roller shutter box is interrupted.

In the main patent CH 503 884 A (Owner: Griesser AG; filing date: August 5, 1969) a roller shutter curtain is described, which is intended to be wound on two winding rollers that are arranged parallel to each other and drive-connected. The rollers should be drive-connected and firmly mounted next to each other in a horizontal plane or one above the other in a vertical plane. As with known roller shutters, the roller shutter curtain can be made of bars or slats. The diameter of the two rollers should be kept as small as possible, adjusted to the bending radius of the shell. The authors suggest preventing the rollers from sagging by providing appropriate support. With the roller shutters described, it should be possible to do without voluminous roller shutter boxes so that window frames can be pulled up to the ceiling.

The utility model DE 20 2011 052 483 U1 (Owner: JOMAdämmstoffwerk GmbH; registration date: December 23, 2011) deals with roller shutter elements, which, according to the exemplary embodiments shown in the three figures, should each have two roller shutter shafts arranged one above the other. The roller shutter shafts should be rotatably mounted and surrounded by a conveyor. The slats of a roller shutter can be connected to one another in an articulated manner, with one end of the roller shutter being able to be attached to the conveyor and wound onto the roller shutter shafts via the conveyor. Particular attention is given in the DE 20 2011 052 483 U1 on measures to improve building insulation against heat loss by means of a component of the roller shutter element known as a molded body, into which the roller shutter element or the roller shutter shaft should be releasably or permanently installed. The shaped body should be formed predominantly from a heat-insulating material.

In the utility model application DE 1 849 457 U (Applicant: WR Maas; filing date: November 3rd, 1961) a roller shutter is described which is intended to have an arrangement of two rollers that can be adjusted or adjusted at a distance from one another. The two rollers must be installed one behind the other in the ceiling or one above the other between the window lintel and the interior wall surface. The rollers should be provided with gears or driving cams that are connected to each other by link chains. How the material of the roller shutters should be designed is not explicitly described, but according to the two illustrations it should be DE 1 849 457 U can be assumed to consist of segments that are flexibly connected to one another. Like exactly the ones in the DE 1 849 457 U The several bearing bores or adjustable bearing shells mentioned above, which can be adjusted in their spacing, are to be formed on bearing bands so that shaft journals can possibly be accommodated, is largely left to the imagination of the reader.

The European patent application EP 1 452 684 A1 (Applicant: Serplast SAS Di Giovanni Marcon &C.; Publication date: September 1, 2004) describes a winding system with a reduced system height specifically as a closure for windows and doors of mobile, cramped, thin-walled accommodation, such as mobile homes, whereby the authors explicitly differentiate it from residential buildings made of masonry (English: “masonry”). A structure with two winding shafts with parallel axes of rotation arranged in a vertical plane or in a horizontal plane is proposed. Installation with axes of rotation inclined to one another in one plane is also considered. The two shafts should be secured in a housing with brackets be. Both shafts should be able to be moved with a small chain that comes out of the housing and should be coupled to one another via a belt or toothed belt.

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

Task

When constructing or modernizing buildings, it has often turned out to be desirable in interested circles to have a locking device available that takes up as little as possible of the interior space of the building. In other words, a space available for the installation of the closure device should be usable better, in particular in a more space-saving manner, so that e.g. B. undesirable compromises for fire protection can be avoided if possible. According to a further aspect, the closure device is intended to enable closure of a building opening assigned to the closure device as quickly as possible, in particular reliably and safely.

Description of the invention

The object according to the invention is achieved by a closure device according to claim 1; A suitable method for assembling a closure device can be found in claim 31. Advantageous further training 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, e.g. B. Consider buildings in which people or animals can stay. The closure device comprises a windable material through which a closure can be formed. Due to the elastic flexibility of the windable material, a radius of curvature of the windable material can be achieved. The fact that the material can be wound up makes it possible to design the closure device in a particularly space-saving manner. The closure can be formed by a curtain or a roller blind, each comprising windable material, e.g. B. if the opening is a window opening or a passage. Locking devices can be used for structures such as listed buildings or special buildings such as check-in halls at train stations, ports or airports, e.g. B. can be installed to close entrances, entrances, exits or passages. It can also be said that a room divider can be formed by the closure device. Due to the small mass to be moved compared to a solid gate, a closure device with windable material can be closed and opened particularly quickly. The closure device preferably offers protection against the spread of flames, heat or smoke.

The locking device can be installed in a building during a construction phase or subsequently as an installation kit. 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 narrow, e.g. B. because it was built to save as much space as possible or because other installations, such as cable harnesses or ventilation shafts, are located above the suspended ceiling. A geometrically adaptable or geometrically adapted closure device can be used particularly advantageously. For the windable material of the closure device, a winding technology that saves space at least in one spatial dimension is preferably used. Coilable material may be in a coiled state as a roll. The windable material can be unrolled from the roll. Material that has been unwound from a roll may also be referred to as rewindable material in an unwound state. In other words, the material that can be wound up can be in two partial states, with part of the material being wound up and another part of the material being unwound. The two material states can continuously transition into one another, e.g. B. when windable material is pulled onto a roll. In view of the presence of a single roll, a wound state can also be referred to as a rolled-up state. An unrolled state that originates from a single reel can also be referred to as an unrolled state. In the unwound state, the windable material can be discharged into an opening, the opening being at least partially closable. The opening can e.g. B. be a ceiling opening in a building. The closure device is particularly suitable for openings in sloping walls. It is possible to divide the room using a closure device, whereby a first room in the building can be separated from a second room in the building, in particular to prevent health-impairing influences, in particular against influences due to fire.

The closure device includes a shaft. The shaft can provide a winding core for windable material. In addition to a first wave, at least one further wave, such as the second wave, can be provided. There is one next to the wave Wrapping spread arranged. In one aspect, a winding spreader provides a winding core extension for windable material. It can also be said that the winding spreader and the shaft together form a winding core that is expanded in at least one direction. In relation to the shaft, it can be said that the windable material can be guided around part of the circumference of the shaft. An analogous consideration applies to the winding spread and in particular to possible further waves, such as a second or third wave. The winding spreader is arranged along the shaft. The winding spread follows an alignment of the shaft, so that we can speak of a parallel arrangement. A parallel-like spacing also exists if an axis that extends parallel to the shaft can be assigned to the angular spread as a construction aid. In other words, the shaft and the winding spreader are at a predetermined distance from one another. Mutually assigned end regions of the winding spreader and the shaft can be arranged next to one another, with preferably a lateral end distance being the same size. Preferably, a length of the shaft is greater than a winding width of the windable material. The wrap spreader may include a plurality of wrap spreader segments. Wrap spreader segments may be spaced apart along a line.

The shaft and the coil spreader are supported as a paired arrangement. A pair arrangement is movable as a unit. If there are two or more waves, one can also speak of a group arrangement in the same sense. One possible movement of the pair arrangement is a pivoting movement. A pivoting movement is made possible by the pair arrangement being about an axis which is z. B. extends along or through one of the existing waves, can be tilted. Rotatability of the pair arrangement is preferably limited by a fixed stop. This makes assembly of the locking device easier. The pair arrangement can also be fixable at a predeterminable angle. The angle is e.g. B. can be determined in relation to an extent of windable material in the unwound state. It is also possible to provide that a mounted pair arrangement can be rotated through a predetermined angle. A rotation angle can e.g. B. 45° or 90°. The rotation angle can also be referred to as the tilt angle, especially if full rotation cannot be carried out. After the angle has been adjusted, the pair arrangement is locked into place on a holder, in particular on a frame side plate. The holder permanently preserves the angular position of the pair arrangement. The pair arrangement is z. B. can be adjusted from a horizontal position to a vertical position if an assembly location is e.g. B. only has sufficient installation space for a vertical position of the locking device under a building ceiling.

In the wound state, the winding spreader and the shaft are together wrapped by material that can be wound up. The windable material may form an envelope around the winding spread and the shaft along a longitudinal extent of the shaft.

In one method, a windable material of a closure device is rolled up. The windable material can also be referred to as a windable material. By rolling up, a wound state is at least partially brought into an unwound state. Material in the form of a roll can be drawn out by the action of gravity or by a drive acting on an end portion of the windable material. In an unrolled state, the windable material extends with respect to the building opening in such a way that a cover for the building opening is formed. The windable material can extend into the building opening. A total length of a wrapable material makes it possible, for. B. to form a curtain closure or a gate that preferably extends over the entire building opening. In other words, the building opening can be closed using wrapable material.

When 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 spreader. The first deflection and the second deflection preferably follow the same direction of rotation.

The shaft and the winding spreader form a pair arrangement which has been placed at a tilt angle and has been snapped to a holder of the closure device.

The rollable material has a layer thickness greater than 0.5 mm, which provides better fire protection.

Like a spiral, the (windable) material surrounds the shaft and the winding spread together. The wrapped material is piled up in a spiral. A single array of windable material is formed along the winding spread and the shaft. The arrangement is spiral-like. It can also be referred to as an arrangement as a spiral. A spiral is a geometric shape that results from a core being successively wrapped around a flat material. The spiral can be seen on a material edge along a longitudinal extent of the windable material, especially when looking at a wave end area is released. In other words, an extension of windable material as a single spiral means that there is not a first part of the windable material as a first spiral and not a second part of the windable material as a second spiral around a shaft. Connection or synchronization problems that could arise from joining together parts of windable material, each in a spiral form, do not arise because a single spiral is to be wound.

The windable material can be brought into a single roll via the winding spreader and the shaft. The material can be stored as a roll. A self-contained gate or a self-contained curtain can preferably be formed from a spiral-like arrangement of the roll material.

Advantageous refinements and further developments are presented below, which, viewed individually, both individually and in combination, can also reveal inventive aspects.

In one embodiment, the closure device can be used particularly advantageously for a fire protection curtain. A fire curtain has a fire protection classification specified in relevant standards. With suitable fire protection materials, there is often a need to use a greater material thickness for a fire protection curtain so that a greater protective effect of the fire protection curtain is achieved. As a result, the closure device also takes up more space. A fire protection closure device includes a fire protection curtain. The fire curtain is rolled up in a first state, the opening state. The windable material of the fire protection curtain is rolled up. The windable material is preferably storable in the open state for a plurality of years without deterioration in windability. In the event of a fire, a building opening can be closed if possible in a few seconds, such as less than 60 seconds, using a closure device, such as a fire protection closure device. A second state is a closure state. In the closed state, the windable material is spread out. In an operating state of the closure device, at least 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 covered. According to a further aspect, the building opening can be released in an operating state.

It is possible to provide the closure device as a roller door. A roller shutter is used to close an opening in a building, such as a portal, as needed. With a roller door, e.g. B. includes two gate leaves, there can be a separate locking device for each gate leaf.

In the wound state, the windable material can preferably be in multiple layers, such as at least two layers. In the wound state, at least a first layer of the windable material is located on the shaft and in the winding spread. The first layer can be followed by a further wound layer, such as a second layer of the windable material. In the wound state, the first layer of the windable material can face both the shaft and the winding spread on a first side. Windable material can be placed on a second side of the first layer to form the wound state.

The shafts may include a shaft material such as steel, light metal such as aluminum or brass, plastic, hardwood, or a composite material. A non-combustible fabric is suitable as a windable material.

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

A spatial cross-section in the building intended for the role of the closure device can deviate from a circular disk or a square and yet the spatial cross-section can still be filled efficiently. The weight of the windable material is distributed over at least one shaft and the winding spread, so that a roll several meters long in particular sags less. The material can be wound more evenly and is subjected to less mechanical stress. The wrapable material is less tense when wrapping. According to a further aspect, the material can be wound in at least one dimension in a more space-saving manner than in known closure devices.

The wrap spreader may include a plurality of wrap spreader segments. Wrap spread segments can be along a line spaced apart from each other. A wave can comprise a plurality of wave segments, which preferably adjoin one another. This makes it possible, among other things, to reduce the overall mass of the closure device. Installation work in a confined space in a building is made easier.

The closure device can have a winding device. Material that can be wound up can be collected through the winding device. Wound material can be discharged from the winding device into the building opening. The winding device comprises at least one shaft and preferably a drive device for the shaft. The drive device can cause the shaft to rotate. A first shaft rotation may result in conveying windable material in a first direction, e.g. B. out of the building opening, with the material being taken together as a roll. A second shaft rotation that is opposite to the first shaft rotation direction can transport material present as a roll into the building opening. Coiled material is in a hollow cylinder-like arrangement around the shafts. The edge area of the material is present on side surfaces that can be geometrically assigned to a single cylinder outside a lateral surface, namely base area and height area. The width of the material to be wound can be referred to as the cylinder height. The spiral-like structure of the roll can be seen in an end area of the material that is assigned to the width. The spiral may be a deformed spiral. A deformed spiral is a spiral that has a constant turn spacing but whose core or evolute deviates from circular symmetry. A constant coil spacing is known from the mathematically idealized form of an Archimedean spiral emanating from a point. A deviation is considered a dimension compared to a circular shape that is larger, preferably at least twice larger 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 adjoins one another in layers. An oval-shaped deformed spiral occurs when a core has a cross-sectional structure that e.g. B. has two convexly oriented semicircles, which are connected by two straight lines arranged on the circumference, in particular parallel to one another. The first semicircle can be assigned to the shaft and the second semicircle to the winding spread. If the first semicircle has a smaller radius than the second semicircle, a trigonally deformed spiral can be formed. A trigonally deformed spiral can also be formed by using two or three shafts for the windable material. With a combination of several waves, the windable material surrounds the waves in roll form like a multi-sided deformed spiral. This means that a shell shape of the roll is particularly suitable for an available space, e.g. B. is specified by a niche, in particular an angled niche, on a building support or a lintel and a ceiling or a wall, adjustable.

There is an intermediate area between the winding spread and the shaft. The intermediate area is a free space area. There is no windable material in the intermediate area. The shaft is located on a first side of the intermediate region. The winding spreader is arranged on a second side of the intermediate region. The intermediate area between the winding spreader and the shaft is at least large enough so that shaft rotation is not hindered. By rotating the shaft and in particular the winding spreader, material that can be wound up can be brought to at least one further side that 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 delimited by windable material. Through the free intermediate region, an imaginary connecting curve can be drawn from the winding spread to the shaft in a region of the width of the windable material, without crossing any windable material. The intermediate region is present in an outer area of the shaft, whereby the shaft can be designed as a hollow shaft. The winding spread can extend, in particular like a comb, in the intermediate region.

The shaft is installed in the closure device, preferably at a fixed distance from the winding spreader. The shafts can be rotated particularly well if they are each rotatably mounted on two pivot bearings. A first pivot bearing is assigned to the shaft. A second pivot bearing can be assigned to the winding spreader. Between the first pivot bearing and the second pivot bearing, the holder, such as a mounting plate or a frame side plate, can extend, which determines the position of the pivot bearings relative to one another. The shaft is assigned a first axis of rotation which extends inside the shaft. The winding spreader is assigned a second axis of rotation, which extends inside the winding spreader. A rotation axis connects two first bearings and two second bearings together. The shaft can be connected to the winding spread in such a way that only the same direction of rotation of the shaft around the first axis of rotation and the winding spread around the second axis of rotation is possible. In other words, either the winding spreader and shaft rotate clockwise or counterclockwise. When using a plurality of shafts, all shafts preferably have the same direction of rotation.

At least one of the shafts and/or the at least one winding spreader is or are connected to at least one motor. The motor can be a bearing of a shaft. The motor provides bidirectional drive, with a first direction causing winding rotation and a second direction causing unwinding rotation of the shaft. An electric motor drive is preferably carried out by an electric motor built into the shaft. The electric motor can be driven by a switchable current, in particular via a current regulator. The use of electrical energy causes mechanical movement. An electric motor enables the shaft rotation to be started quickly and a direction of rotation to be changed quickly, so that a wound-up state or an unwound state of the windable material can be achieved very quickly. Further embodiments have a compressed air motor or a hydraulic motor as a motor, in particular if there is a corresponding pressure medium supply in the building. The engine can e.g. B. drive at least one pulley or at least one gear. It is possible to operate at least two motors with, in particular electronic, rotation synchronization.

It is possible to provide an outer diameter of the shaft that is different compared to an outer diameter of the winding spreader. With the help of the selected outer diameter, the force to be applied to the windable material during winding can be transferred to the bearings in a particularly favorable manner. Different outside diameters, such as a first outside diameter and a larger second outside diameter, especially when using two or more shafts, can serve to form an advantageous roller geometry.

A rotation of the shaft and a rotation on the winding spreader can be synchronized particularly precisely with one another if a motor drive is transmitted from the shaft to the winding spreader or vice versa, depending on the arrangement of the motor drive on the shaft or winding spreader. Rotation can be mediated via a drive belt. As an alternative, the winding spreader can include a motor drive. The drive belt is arranged such that it connects the shaft and the winding spreader together. Preferably, the drive belt surrounds the shaft and the winding spread. The wave can be composed of several waves. The drive belt can rest on at least one pulley that is firmly connected to the shaft. An example of a drive belt is a flat belt. It is also possible to provide a circumferential, preferably step-structured shape, such as a groove shape that has at least one recess, for the drive belt on one or possibly several shafts. This allows static friction to be increased. In a particularly space-saving embodiment, the drive belt can run in a recess on the shaft and in a recess on the winding spreader, in particular on a second shaft. A plurality of drive belts can be arranged along a longitudinal extent of the shaft, e.g. B. with a distance of at least ten centimeters (cm) between two drive belts. This results in a particularly even distribution of force between the shaft and the winding spread. The drive belt has a first surface facing the shafts. A second surface of the drive belt facing away from the shafts can 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 can be specified by a thickness of the drive belt and a pulley or gear rotation size. In this way, frictional wear of the windable material, e.g. B. due to dust or sand grains, should be kept as low as possible.

A plurality of gears can be arranged on a shaft. Pulleys can be used as an alternative to gears. A gear wheel, which in particular guides a belt laterally, can also be referred to as a pulley. At least two gears are preferably located along a longitudinal extent of the shaft. The gears on a shaft are at a fixed distance from each other. A winding spreader can include at least one gear. A gear or a pulley can be rotatably arranged on a winding spreader segment. The arrangement can e.g. B. be chainsaw-like. A first gear on the shaft and a second gear located at or on the winding spreader form a group, the gears being spaced apart from one another. A revolving drive belt, such as a toothed belt, or a revolving chain preferably extends between the grouped gears. A toothed belt has a particularly smooth surface for supporting the windable material. A drive belt, such as a toothed belt, preferably includes an embedded tension cord, which usually consists of glass or aramid fibers or steel cables. One tooth side of the timing belt is preferably made of abrasion-resistant fabric in order to protect the elastomeric teeth from wear. A drive belt can e.g. B. include a fiber-reinforced plastic or a fiber-reinforced rubber. A drive belt runs very quietly.

The windable material has at least one end portion that extends 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 pushing force can be applied to the end region of the windable material by the toothed belt. A first toothed belt can z. B. be arranged parallel to a second toothed belt at a distance of at least 10 cm, preferably 1 m. The timing belt has e.g. B. a width of 1 cm. The toothed belt has teeth for engagement of the first gear and the second gear. The use of a chain is advantageous if the material that can be wound up is particularly heavy. 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 can also be a shaft diameter. The gears that belong to the winding spreader have the same second diameter. The second diameter is preferably a maximum diameter. The second diameter can 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 can deviate from the spiral around an oval spiral core.

A longitudinal extent of the shaft can e.g. B. up to 6 m and more. It is possible to reinforce the closure device with at least one stabilizing strut. Bending or sagging of the shaft can be prevented using a stabilizing strut. According to one aspect, the stabilization strut is a stiffener of the closure device. The intermediate area along the shaft is available to accommodate a stabilization device. The stabilization device can include the stabilization strut. The stabilization strut preferably extends along the shaft. A stabilization strut that is designed as a trapezoidal profile rod, a U-profile rod or a hollow profile rod is particularly stable. The stabilization device can be connected to the winding spreader. According to a further aspect, the stabilization device can comprise at least one shaft support element. The shaft support element is attached to the stabilization 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 spreader, the stabilizing strut and/or the shaft support element. A stabilization strut that is attached to the mounting plate provides particularly good support. The mounting plates extend at the end regions of the shaft. Preferably, a first support plate and a second support plate are provided associated with respective first and second ends if a plurality of shafts are provided. The stabilization strut can be welded to the mounting plate. It is also possible to attach the stabilization strut to the mounting plate using a stabilization strut bracket. An attachment is e.g. B. possible by a screw connection, a rivet connection or a plug connection. The stabilization device can be present as a diagonal strut in the intermediate area. The diagonal brace forms an angle to the shaft. The stabilization device can also be provided as a cross stabilization. A cross stabilization has at least four stabilization sub-struts, each of which can be attached to a mounting plate and has a common connection area. Cross stabilization is particularly advantageous if the shaft and the winding spreader or another shaft are at a distance of more than 20 cm, e.g. B. have more than 50 cm or more than 100 cm to each other.

A closure device in which the shaft and the winding spreader are mounted in a common frame is particularly robust. The frame can e.g. B. be a cuboid structure that has a hollow profile rod on a plurality of edge areas. To protect against contamination, the shaft and the winding spreader as well as the windable material are preferably accommodated in a housing in the wound state. The frame can be part of the housing. Side surfaces can 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, the distortion of which must be avoided as far as possible to ensure operational reliability 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 fabric or film does not put any strain on the closure device. The effects of a temperature gradient across the frame on the shafts and in particular the rotation of the shafts remain as low as possible. In addition, the windable material is protected from dust and other contaminants. Even better protection, e.g. B. against the spread of smoke particles, offer a fabric and/or a film material, such as a fiber-reinforced film, which are suitable for fire protection. The weight of the locking device is determined by Ver The use of fabric and foil is kept as low as possible, which, among other things, makes installation easier.

An advantageous development of the device is based on at least one winding spread, preferably at least bidirectional winding spread. In other words, it is possible to view a shaft, in particular a shaft segmented in a longitudinal direction, as part of a winding spread. The closure device comprises a windable material. The windable material can be in a wound state and an unwound state. A first portion of the material may be in a coiled state and a second portion of the material may be in an unwound state. In the wound state, the windable material preferably surrounds the winding spread in at least two layers.

This means that the shape of a wound state can be adapted particularly well to spatial specifications.

It can also be said that the winding spread specifies or limits a winding core which deviates from a circular shape in a cross section along a width of the windable material.

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

A gear or a pulley can be rotatably arranged at an end of the expansion strut facing away from the stabilization strut. A first expansion strut and a second expansion strut and possibly further expansion struts are aligned with one another in such a way that a plurality of gears or a plurality of pulleys can be connected to a ring-like drive belt for transmitting rotational force. According to a first aspect, the drive belt carries the windable material. According to a further aspect, the windable material can be transported around the winding spreader by the drive belt.

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

The windable material can be stretched with a variable length over or through a building opening.

For fire protection, for example, B. an aramid material as a film or as a fabric. It is also possible to use fiberglass fabric. A layer material in which materials such as films or fabrics are combined with one another in order to combine their specific advantages, such as high heat insulation, high tightness and low burn-off, is particularly advantageous. The windable material is preferably a non-combustible material. One option for a non-combustible material is a fireproof fabric in which heat and fire-resistant fibers are woven together. It is possible to use an open mesh fabric, such as a fiberglass fabric, which has an intumescent coating. In one embodiment, the fibers can stick through the coating at a temperature of 100°C. At a temperature of 150°C, the pores of the fabric are closed. The coating foams at a temperature of 200°C. An insulating layer, such as insulating foam, is formed on the fire protection fabric, which acts as a heat brake. A fire protection film is preferably reinforced by wires or fibers drawn into the film in order to better withstand mechanical stress. A coilable material that has a first layer and a second layer is even more stable. Preferably, the first layer and the second layer completely overlap each other. A rollable material can have a layer thickness of less than 0.5 mm. Better fire protection is achieved by a layer thickness greater than 0.5 mm. Good protection is provided, for example: B. a total layer thickness of a, preferably multilayer, windable material of at least 4 mm. With a layer thickness between 10 mm and 20 mm, particularly good fire protection can be achieved with good windability and durability against mechanical stress. Layer thicknesses of up to 30 mm, preferably less than 100 mm, can be used as windable material. This makes it possible to provide a particularly long resistance to fire in the event of a fire. The locking device is suitable for newly constructed buildings as well as for historical buildings. Through the ver Closing device is a particularly large opening cross-section at building openings, e.g. B. can be released for a passage because the closure device itself is very space-saving. It is also possible to integrate the closure device more harmoniously into the architectural structure of the building in a wound state.

The combinations and exemplary embodiments presented above can also be considered in numerous other connections and combinations.

Character description

The ones in the 1 until 9 The representations shown of embodiments of the closure device 2, 102, 202, 302 and 402 have many similarities, which are only explained using individual embodiments or figures to avoid repetition. The respective numerical values are reserved for corresponding objective characteristics, differentiated in increments of “100”.

The locking device 2 in 1 relates to a roller door 4. The roller door 4 is mounted in a ceiling area 9 of a building 8 and is used to close a building opening 11. The closure device 2 has a frame 80 which is attached to the ceiling area 9 with the frame fastening 82. On the frame 80 there is a covering support 88, onto which a covering material 89 for a first side surface 85 of the frame 80 can be pulled. The covering material 89, dashed in 1 entered, can also cover a second side surface 86 up to the sealing rail 92. An insulation board 12 offers heat protection for the closure device 2 on another side surface (without reference number). The cross-sectional view of 1 reveals a first side plate 81 which is attached to the frame 80. A second side plate (not shown) designed in accordance with the first side plate 81 is located opposite the first side plate 81 on the frame 80. On the first side plate 81, a suspension support 78 is slidably mounted on elongated holes, such as the elongated hole 79. The suspension support 78 carries a winding spreader 30 via a first pivot bearing 48, which is in the embodiment of 1 and 2 is designed as a wave. Another first pivot bearing (in the sectional drawing of 1 not shown) allows the winding spreader or shaft 30 to be rotatable about a first axis of rotation 51. The winding spreader 30 has an outer diameter 33, on which a first gear 56 with a first gear diameter 57 is fastened, with a gear driver 62, like a welding point, securing a connection between the first gear 56 and the shaft 30 against rotation. The sealing rail 92 extends parallel under the shaft 30, which, among other things, increases the stability of the frame 80. 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 circumferentially continuous teeth, such as the tooth 65, which faces the gear 56. The drive belt 64 provides a support surface 68 for wrapable material that can be mounted at an attachment point 67. A shaft 32 is provided, which can be driven by an electric motor 54. Thus, the wave 32 can be referred to as a first wave. A shaft driver 55 transmits a driving force from the electric motor 54 to the shaft 32 using the shaft driver 55. The motor 54 provides a second pivot bearing 49 that enables the shaft 32 to rotate about a second axis of rotation 52. By the rotation of the shaft 32 by means of an electric motor 54, a second gear 58 drives the drive belt 64. The drive belt 64 sets the winding spreader 30 or shaft 30 in rotation via the first gear 56. The shaft 30 has a first outside diameter 33 which is the same size as the outside diameter 31 of the driven shaft 32. The second gear 58 has a second gear diameter 59 that is larger than the first gear diameter 57 of the first gear 56 on the winding spreader 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 designed in the same way as the first gear group and is covered with a drive belt, can be installed. The elongated holes, such as the elongated hole 79, on the suspension support 78 serve to adjust the shaft distance 34 between the first axis of rotation 51 and the second axis of rotation 52 fixed by the drive support 76 so that the drive belt 64 lies tensioned on the gears 56, 58.

In the cross-sectional view of 2 a windable material 13 is shown in the closure device 2 designed as a roller door 4. There is a role 19 in the closure device 2. An end region 14 of the windable roller door material 13 is mounted on the drive belt 64 at the attachment point 67. The support surface 68 of the windable material 13 is formed on the drive belt 64. The windable material 13 lies as a spiral 20 around 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 2 the edge region 22 of the windable material 13 is covered. 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 region 42, which is on a first side 43 through the shaft 30 and on a second side 44 is released by the shaft 32. On a third side 45 and a fourth side 46, the intermediate area 42 is delimited 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 an unwound state 17. The wrapable material 13 has a first layer 23 and a second layer 24, which are firmly connected to one another. A total layer thickness 27 of the windable material is 10 mm. Starting from a wound state 16, the unwound state 17 can be brought out through the outlet opening 95, whereby the roller shutter 4 can form a closure (not shown).

In the cross-sectional view of a closure device 102 in 3 became, as in 1 , windable material 113 omitted for clarity. In 4 is, similar to 2 , the windable material 113 is shown, which is intended for a fire curtain 106 of the closure device 102. The closure device 102 has a frame 180 and is held in a ceiling area 109 of a building 108 using a frame fastening 182 above a building opening 111. A guide rail 190 extends along the building opening 111 and 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 in 4 is shown, a lateral guide of an edge of the windable material 113. The closure device 102 in 3 comprises a shaft 132 and a winding spreader 130, on which a first gear 156 and a second gear 158 can be rotated in the same direction of rotation 153 by means of a toothed belt 164. The gears 156, 158 are drawn transparently in order to make the underlying arrangements easier to see. The winding spread 130 is segmented along the shaft 132, that is, in other words, not continuous in a wave-like manner. The individual winding expansion segments are connected to the stabilization strut 170 or to the frame 180. A clockwise direction of rotation 153 is shown by arrows as an example. In 3 A clockwise rotation corresponds to a winding rotation exerted on the shaft 132 by an electric motor 154 to create a wound state, such as the wound state 116 in 4 . A particularly good load-bearing capacity of the winding spreader 130 is achieved by interlocking the suspension support 178 of the winding spreader 130 with another suspension support 178'. The suspension support is assigned to the winding spreader 130. Forces exerted on the winding spreader 130 by the direction of rotation 153 are at least partially diverted to the frame 180 via the suspension supports 178, 178`. A drive support 176, which is assigned to the electric motor 154, has elongated holes, like the elongated hole 177. The shaft 132 is displaceable with respect to the winding spreader 130 in order to be able to tension the toothed belt 164. The stabilization strut 170 extends in an intermediate region 142 and is connected to the frame 180 via a stabilization strut holder 174. The intermediate region 142 extends around the stabilization strut 170 from a first side 143, on which the shaft 132 is located, to a second side 144, on which the winding spreader 130 is located. The stabilization strut 170 leaves the intermediate area 142, which is opposite the toothed belt 164, free to such an extent that the teeth, such as the tooth 165, can be guided along the stabilization strut 170.

In 4 the intermediate area 142 is limited on the further pages 145, 146 by the windable material 113. The toothed belt 164 serves to form a support surface 168 with the windable material 113. The windable material 113 is in the form of a roll 119. By rotating the electric motor 154 in the direction of rotation 153' counterclockwise, the shaft 132 can be driven and the winding spreader 130 can be driven in the same direction of rotation 153' by means of a toothed belt 164. 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'. The building opening 111 can thus be closed. At the end region 114' there is a sealing body 121, which serves to attach the fire protection curtain 106 to a floor region (not shown). When unwinding in the direction of rotation 153', the fastening point 167 runs at an end region 114 of the windable material 113, which can also be referred to as the winding end region 114, around the winding spreader 130 and around the shaft 132. In a time sequence of a toothed belt movement, a distance between the fastening point 167 and the winding spreader 130 can be periodically increased and reduced again. When the windable material 113 is unwound, the intermediate region 142 remains free of windable material 113. The windable material 113 has a first layer 123 and a second layer 124, between which there is a swellable intermediate layer 125. In an unrolled state 117 that can be created for a closure (not shown) of the building opening 111, an improved seal against the passage of smoke can be created by means of a swelling tape 193 which is glued to the sealing rail 192 with sufficient heat development. Another sealing rail 192' with a swelling tape (not shown) on the in 3 Designated outlet opening 195 can provide sealing against the windable material 113 in the closure device 102 4 improve even further.

5 and 6 show a further embodiment of a closure device 202 for a fire protection curtain 206. If necessary, e.g. B. in the event of a fire alarm, building opening 211 to be closed is located under a wall area 210 of a building 208.

In the embodiment of the 5 and 6 In comparison to the other embodiments, driven and guided shafts or winding spreads are exchanged to make it clear that the invention is independent of the positioning of active and passive shafts or active and passive winding spreads.

The closure device 202 is screwed onto the wall area 210 with the frame fastening 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. A first mounting plate 272 is rotatably attached to the first side plate 281 about an axis 236. A first shaft 232 and a second shaft 230 extend from the first mounting plate 272 as a pair arrangement 235. The shafts 230, 232 are each rotated together in the same direction of rotation, which is in the 3 and 4 is shown by the electric motor 254 in 5 rotatable, in particular rotatable. A rotational movement of the shafts 230, 232, which can also be referred to as shaft rotation, is mediated by a toothed belt 264. By lowering windable material 213, a roll 219 can be made smaller. The roll 219, also referred to as a winding, is located on the winding device 207, with a support surface 268 being present between the toothed belts, such as the toothed belt 264, and the windable material 213 of the roll 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. There is a variable angle 239 between the winding device 207 and the guide rail 290, in particular in relation to the mounting plates of the winding device 207, such as the first mounting plate 272. The angle 239 can also be between the building 208 or the wall area 210 and an imaginary, axial connecting line between the shafts 230, 232 can be located. The shaft 230 of the pair arrangement 235 can be approached to the wall region 210 by rotating 238 about the axis 236. For example, during assembly, an adjustment of the winding device 207 is possible. The timing belt 264 is adjustable to extend in a straight range in a direction of the guide rail 290. The angle 239 can z. B. 90 ° without the building opening 211 being narrowed by the winding device 207. An angle, such as angle 239, can be taken, which is preferably greater than 0° and in particular less than 180°.

In 6 the closure device 202 is shown with a position of the winding device 207 in which an angle 239 in 5 enlarged angle 239` is taken. By rotating 238, 238` of the winding device 207 in 6 , which can also be referred to as tilting 238, 238`, the angle 239, 239` can be changed to a selectable, fixed end position. The edge region assigned to a mounting plate, such as the first mounting plate 272, such as the edge region 222, of the roll 219 of the windable material 213 is in the form of a spiral 220. The leadership Rail 290 assigns a predetermined direction to the edge region 222, which continues from a wound state 216 into the unwound state 217. At the rotation 238` in 6 as well as the rotation 238 in 5 the frame 280 and the side plate 281 remain stationary on the wall area 210. As in 6 As can be seen, the winding device 207 can be positioned by rotation 238 to rest on the wall area 210. The angle 239` in 6 locates the roller 219 closer to the wall area 210 than the angle 239 in 5 . This allows the closure device 202 to be placed on the wall area 210 with as little of a front as possible. A space segment located above the side plate 281 in front of the wall area 210 can be filled by the closure device 202. A niche above the closure device that may be undesirable for aesthetic reasons is not completely lost as a cavity that needs to be shielded.

7 is a spatial representation of a side region of a closure device 302, again omitting windable material for better clarity. The closure device 302 includes the winding device 307, which includes a first shaft 332 and a winding spreader 330. The winding spreader 330 is designed as a second wave 330. The illustrated side region of the winding device 307 has a first side plate 381 and a first mounting plate 372, to which mirror symmetry in a second, not shown side region of the winding device 307 to the right of the 7 a second side plate and a second mounting plate are provided. The winding device 307 includes a plurality of gears, with the first gear 356 and the second gear 358 shown as an associated pair. The first gear 356 is connected to the second gear 358 via a drive belt 364. One of the second gears, namely the second gear 358 shown, is located on the first shaft 332 in proximity to the drive support 376, which is used to mount a motor for driving the first shaft 332. The side plate 381 has a fastening element 382. The first side plate 381 can be firmly connected to the first mounting plate 372. The first mounting plate 372 has a fastening element 382'. The fastening elements 382, 382' are intended for ceiling mounting of the closure device 302. A stabilization strut 370 is installed in an intermediate area 342 between the first shaft 332 and the second shaft 330. The stabilization strut 370 has a trapezoidal hollow profile that is open on one side in cross section. The stabilizing strut 370 is attached to mounting plates, such as the first mounting plate 372, by screws (unnumbered). The second shaft 330 is guided by a shaft support element 371 which is attached to the stabilization strut 370. The sealing rail 392 extends parallel to the second shaft 330. The sealing rail 392 has a trapezoidal hollow profile that is open on one side in cross section. The seal rail 392 is attached to side plates such as the first side plate 381. Insulation panels, such as the insulation panel 312' and the insulation panel 312", are arranged around the sealing rail 392. The insulation panels 312', 312" serve to thermally insulate the sealing rail 392, so that the sealing rail in the event of increased ambient heat of e.g. B. 100 ° C retains its shape as much as possible.

A cross-sectional view of the closure device 302 is shown in FIG 8th shown. The closure device 302 is mounted in the ceiling area 309. The first shaft 332 is held on the drive support 376 and can be positioned in elongated holes such as the elongated hole 377 of the drive support 376 on the mounting plates, such as the first mounting plate 372. There is a first adjustment option for the winding device 307, which serves to tension the drive belt 364, which surrounds the shafts 330, 332. Windable material 313 is placed on the winding device 307 in a wound state 316 as a roll 319. From the roll 319, windable material 313 hangs down in an unwound state 317 to such an extent that windable 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 fire protection curtain 306 by applying the windable material 313 into the unrolled state 317, in other words. The winding device 307 is protected from heat input by insulation panels, such as the insulation panels 312, 312 ', 312", so that room heating can only have a time-delayed effect on the winding device 307. Sufficient operational reliability of the closure device 302 is ensured. The closure device 302 is secured by both Sealing rail 392 and also by the stabilization strut 370, which is located in the intermediate region 342, are supported against possible warping, so that the winding device 307 remains dimensionally stable even in the event of a fire. The first side plate 381 has a shaft receiving slot 383 into which a shaft axle pin 384, which forms the end of the second shaft 330, can be inserted to fasten the second shaft 330.

Another embodiment of a closure device 402, shown in a cross section in 9 shown is based on the winding device 407, which in particular has similarities with the winding device 307 in the 7 and 8th having. Areas of the closure device 402 that are covered by windable material 413 are shown in dashed lines draws. There is a pair arrangement 435 which includes the first wave 432 and the second wave 430. The first wave and the second wave can each be referred to as a winding spread according to one aspect of a winding core expansion. The pair assembly 435 is held together by two mounting plates, such as the first mounting plate 472. The pair arrangement 435 has an intermediate region 442 in which the stabilization strut 470 extends. On the pair arrangement 435, windable material 413 is placed, which is arranged as a roll 419.
