Description

DEVICE, METHOD OF APPLICATION, METHOD FOR TURNING A DEVICE, CONSTRUCTION SET AND ARRANGEMENT

The invention relates to a device for displaying images or films, a method for illuminating and / or advertising by means of the device, a construction set for the device and an arrangement of the device.

DE 20 2013 008 404 Ul discloses a device according to the preamble of claim 1, namely a mobile lighting device with a translucent sheath of a woven or flexible plastic material, which is stretched by wires or cables between two spaced-apart structures. The device contains illuminants, and the envelope can serve as a projection surface for internally projected images, motifs or moving images. Fans mounted inside the device can inflate non-taut area. The envelope may be in the form of sheet material that can be connected to a tube by a zipper. The shell may consist of materials of building material class A2 (non-combustible with combustible fractions) or B 1 (hardly inflammable) according to DIN 4102-1 and have opacity to scatter a high proportion of the light. The bulbs can be mounted as LED strips along the wires or ropes, or the LED strips themselves can be used for clamping.

All previously known media systems for displaying images or films, which of course can also contain text, exert a fire load on their installation site. The fire load is related to a certain surface heat potential of all flammable substances present on it. The arithmetic fire load is the fire load modified with corresponding coefficients and is used for the determination the equivalent fire duration for a given fire load or amount of fire and firing arrangement. This in turn can be used to determine the required fire resistance period of a building construction.

The exposure to fire caused by media installations often prohibits them from being installed in public spaces where the allowable fire load has already been exhausted, such as: B. airport buildings. From DE 202 18 388 Ul it is indeed known to install in a device for the projection of photographs on advertising space smoke detector, which can turn the device dead, but this does not reduce the actual fire load.

The situation is even more difficult for internally lit medial installations such as B. planar LED displays whose outer walls usually consist of combustible plastics. In particular, the transilluminated front usually consists of a transparent combustible plastic and can usually not be replaced for reasons of weight and cost by fire-resistant glass, which would have to be extremely thick.

The invention is based on the object to provide an easily transportable device for displaying images or films with a shell made of a translucent, flexible, airtight and non-combustible material and a method for lighting and / or advertising, which are suitable, the admission requirements for meet public spaces.

This object is achieved according to the invention by an apparatus and a method having the features specified in the claims 1 and 16.

Advantageous developments of the invention are specified in the dependent claims.

Indefinite articles are each to be understood as "at least" information, unless stated otherwise. The fire protection device according to the invention, which releases an extinguishing agent in the interior in the event of fire detection, makes it possible to make the device intrinsically safe. That is, the effective fire load applied by the device to its installation site can be made equal to zero or even less than zero.

For a fire which breaks out in the interior, this can be achieved by appropriate dimensioning of the quantity of extinguishing agent which is kept ready and to be released in the event of fire detection. The amount required for this is not very great in the device according to the invention, because virtually all mechanical components can consist of non-combustible substances and essentially only the risk of fire due to the electrical, electronic and LEDs based fire risk must be compensated. And a fire coming from outside does not get inside because of the non-combustible shell.

The extinguishing agent may be per se any commercial extinguishing agent for fire fighting, but is preferably an extinguishing gas, which may be an inert gas, but more preferably is a chemically acting extinguishing agent, in particular a fluoroketone such. B. 3M ™ Novec ™ 1230 Fire Protection Fluid. Within the inflated envelope, the extinguishing agent readily passes everywhere without the need for any manifolds or the like.

Conveniently, the extinguishing agent is not released only when open flames have arisen, but already preventative when one of one or more arranged within the shell smoke detectors reports a smoke.

In a preferred embodiment, the shell of one or more materials of building material class AI according to DIN EN 13501-1 and / or DIN 4102-1, ie, non-combustible without combustible fractions. Because of the built-in fire protection device, the admission requirements for public spaces may possibly also be met with coating materials of building material class A2. The material of the shell is preferably such that the shell assumes a defined shape in the inflated state, which is mainly determined by the blank of the shell material and less by the support structure and / or the air pressure in the interior, as in the cited prior art of Case is. In addition, the material of the shell should be inherently diffusely translucent (ie, translucent).

The inventors have recognized that there are suitable materials for the shell, which meet all the aforementioned requirements in contrast to the materials proposed in the cited prior art. Particularly suitable is a textile which has glass fibers or other non or hardly inflammable fibers. Many such materials also have relatively low extensibility, such that the inflated envelope assumes a well defined shape when inflated, and many such materials also have the advantage of being inherently translucent.

All of these properties have particular fiberglass fabrics, as z. B. also be used for fire blankets.

In a preferred embodiment, a plurality of the bulbs, but not necessarily all, are affixed to the inside of the sheath and not to any of the sheath-supporting parts, as in the cited prior art. These lamps together form a pixel matrix with a curvature corresponding to the shape of the inflated envelope. For this purpose, the lamps are relatively close to the shell, so that a part of their waste heat passes through radiation or heat conduction directly to the outside, which additionally reduces the fire potential.

The bulbs can be of any kind per se, but they are in a preferred embodiment, a plurality of LED strips, namely elongate flexible boards, each equipped with many, preferably individually or in groups controllable LEDs and the non-destructively detachable at their ends and reconnectable connections for connection with each other or with control electronics have. In this case, each LED strip is carried in an elongated profile, wherein the profiles are attached at close intervals next to each other on the shell and are designed so that they hold all LEDs at a defined distance from the shell, which is preferably the same everywhere and a few millimeters is, wherein the main beam direction of the LEDs facing towards and through the shell. The thus produced distance of the LEDs from the shell thus remains constant, even if the shape of the inflated envelope z. B. slightly varied by air currents at the installation site.

The profiles are preferably made of a soft, flexible and insulating material, in particular sponge rubber or the like, and can be produced in an injection molding process. Corresponding open or closed-cell elastic foams are available in flame-retardant or non-combustible form, as preferred in the present case. Because of the existing fire protection device, and because a part of the waste heat of the LED tapes passes directly through the nearby envelope to the outside, it is sufficient if the profiles and LED strips are classified together in the building material class Bl.

Preferably, the profiles are non-destructively releasable and reconnect attached to the shell, z. B. by spring steel clips and / or blind rivets or by means of Velcro strips. Depending on the size of the device and the desired pixel resolution z. B. more than 100, 200, 300, 400, 500 or 600 in the shell adjacent LED bands or profiles may be provided.

Although the profiles are in a preferred embodiment of a flexible and insulating material, they may also consist of a more or less rigid material, for. As aluminum, if it can be ensured that they are not permanently bent during transport. Possibly. Such rigid profiles can be composed of several sections, which are more or less loosely connected to each other at their ends. In a preferred embodiment, the shell is supported by a single supporting structure, which is arranged in the interior of the shell, and not by two structures, as is the case in the cited prior art. This embodiment is particularly suitable for hanging mounting in a building, wherein the inflated envelope or at least one concave envelope portion carrying the illuminants faces downwards.

The fire protection device including a smoke detector as well as all required electrical and electronic including power supplies and LED control electronics can be arranged in the interior of the shell and attached to a supporting structure, and one or more outwardly opening louvers and preferably also the blower can be integrated into the shell.

By making the shell parts and / or the bulbs non-destructively detachable and re-connectable, shell parts and / or bulbs can be easily replaced, so that the device can be easily converted, repaired or maintained.

Further, it is also advantageous regardless of the other features of the invention, when the interior is sealed at a connecting line or a shock or the like by two pressed together textile parts. In this way, the reliability can be further increased, since especially in the case of a fire is particularly well prevented that atmospheric oxygen can flow from the outside into the interior.

Not only in this specific context, it is advantageous if two pressed together textile parts are pressed against each other with spring support. This can be done in a variety of ways, with a very simple construction corresponding elastic rubber elements comprises, which press the textile parts together.

A particularly advantageous embodiment variant provides that the device comprises an adjustable clamping device, by means of which textile parts are tensioned. It is understood that corresponding clamping mechanisms can be realized in many ways. Also related features are advantageous regardless of the other features of the invention, since these features evolve generic devices alone advantageous.

Furthermore, it is of particular advantage if the device comprises a deflection device, by means of which textile parts with a larger radius are deflected around edges of the device. As a result, the risk of breakage, in particular with regard to glass fiber textiles or the like, can be significantly reduced, as a result of which the safety of the device can be further increased. By avoiding unwanted fiber breaks in particular the risk is reduced that atmospheric oxygen can inadvertently get from the outside into the interior of the device.

A sufficiently large radius may for example be provided by a correspondingly shaped rubber profile element.

Furthermore, if deflection means of the deflection device are configured elastically, the risk of fiber breaks can be further reduced.

The embodiments of the invention enable a compact and easily transportable construction kit even for a device with very large physical dimensions.

The invention is particularly suitable for the arrangement inside a public transport building, especially in an air area above 2 m, 3 m, 4 m or 5 m, preferably hanging in an airport building.

With the invention, a novel digital display for so-called. Out of Home Media is created, which achieves special attention in closed public spaces, in particular by a sculptural form that unfolds its media effect in 360 °. The display is hung in the room so that it presents itself in the direct direction of people. Moving 360 ° images can rotate in a circle and thus all Reaching people in the room. The content can switch between promotional videos and news from online magazines. Only few people can ignore recent news headlines. Thus, the view will always capture advertising, which can be present in a backlit slide in a lower part of the device constantly. The viewer can learn more about news or products by scanning a QR code at the bottom of the device with his mobile device, looking back at the advertisement. Thus, the invention offers advertisers novel presentation options in striking locations while allowing airports, train stations and trade fairs attractive billboards, which integrate creatively into the given architecture.

This type of public spaces increasingly require installations that meet the requirements of building material class AI. These requirements are met in the invention in a special way by intrinsic safety. That is, the device has an effective fire load that is zero or even less than zero, and thus corresponds to an object consisting only of materials of building material class AI, although the device contains electrical and electronic equipment. Due to the thus achieved fire load neutrality, an official approval is also for buildings whose allowable fire load is already exhausted, nothing in the way.

It is understood that the features of the solutions described above or in the claims can optionally also be combined in order to implement the presently achievable advantages and effects in a cumulative manner.

The apparatus shown in Fig. 1 for displaying images or films contains a shell 1 made of a fiberglass textile, which is diffusely scattering translucent, airtight, non-combustible and flexible, but low in stretch. The shell 1 is substantially airtight closed and is inflated by a fan 2 in a balloon shape, which is the surface of a concave body of revolution whose central axis is vertical in Fig. 1. The shell 1 defines an interior 3. The balloon shape may have a diameter of several meters, z. B. 6 meters.

The shell 1 includes a barrel-shaped portion 1a having, in particular, the shape of an axial portion of a barrel approximately from the center thereof to near one end thereof. The barrel-shaped portion la merges at its narrower, lower end without abrupt change in curvature in a spherical cap-shaped portion lb, which closes the narrower end of the barrel-shaped portion la. At its other, upper end of the barrel-shaped portion la is closed with a flat concave portion lc. The sections la, lb, and lc, which make up the sheath 1, are connected together along their connecting lines 4, 5 by zippers, not shown.

The shell 1 is supported by a supporting structure 6, which is a disc-shaped lightweight tubular construction, which may be composed of several angle segments, for. B. from twelve identical and screwed together angle segments to be easily transportable. The structure 6 is suspended from a ceiling or false ceiling structure of a building by means of three cables, not shown, which together with a power cable can pass through narrow openings in the flat concave portion 1c of the casing 1.

The supporting structure 6 is located completely inside the casing 1 and extends all the way to close to the annular zipper connection 5 between the barrel-shaped section 1a and the flat-concave section 1c, where it can be connected to one of these sections. Thus, the structure 6 also contributes to the shaping of the shell 1, although its balloon shape is determined primarily by the blank of the shell 1 and its constituents.

The flat concave upper portion 1c of the shell 1 need not be made of the same material as the portions 1a and 1b of the shell 1, but may be made of another one airtight, non-combustible and flexible material. The upper portion 1c could also be formed by the structure 6 itself if it is constructed to be impermeable to air in any way and, in conjunction with the portions 1a, 1b of the shell 1, surrounds the inner space 3 airtight.

The blower 2 is a pipe fan which is integrated with the shallow concave portion 1c of the sheath 1, that is, the shroud 2. H. is built into and carried by it. The blower 2 could alternatively be attached to the structure 6 and z. B. be connected via a bellows with a corresponding opening in the section lc of the shell 1.

In the flat concave portion lc of the shell 1 also a plurality of louvers 7 are integrated, which open in the manner of check valves to the outside, when a predetermined air pressure in the interior 3 of the shell 1 is exceeded, so that a defined air pressure in the interior 3 of the shell 1, which is slightly larger than the pressure of the ambient air when the fan 2 is running, and thus generates and stabilizes the balloon shape of the shell 1.

In a center 8 of the structure 6 is space for electrical and electronic, which is required for the operation of the device, and LED driving electronics 9 are mounted separately therefrom and closer to the outer edge of the structure 6.

Below the center 8 an extinguishing gas generator 10 located in the interior 3 is attached to the supporting structure 6, which, if one of one or more smoke detectors, not shown in the interior 3 responds, releases a quenching gas, which is preferably 3M ™ Novec ™ 1230 fire protection fluid, but z. B. may also be an inert gas.

Below the extinguishing gas generator 10, a platform 11 is fixed to the supporting structure 6, on the underside of a floodlight from LEDs, not shown, or other bulbs are attached, which illuminate the spherical cap-shaped portion lb evenly within a cone 12. The spherical cap-shaped section lb can with Texts and / or images are printed, which are well visible by the backlight, and with a change of the advertiser on the section lb can be easily replaced.

The barrel-shaped portion la of the shell 1 is smaller in FIGS. 2A and 2B than in FIG. On the inside of the barrel-shaped portion 1a of the shell 1 are fixed a plurality of LED strips 20 which are equally spaced from one axial end of the barrel-shaped portion 1a to the other, and only two of which are shown in Figs. 2A and 2B in fact many LED strips 20, in this example 600 LED strips 20, in the cover 1 adjacent LED strips 20 are distributed over the entire circumference of the barrel-shaped portion la.

In Fig. 2B, the LED strips 20 are shown in dashed lines, because the preferred for the shell 1 fiberglass fabric is so opaque that the LED strips 20 are barely visible from the outside, as long as they do not shine. Groups of multiple LED strips 20 may each have a controller which is located in a sewn pocket at the top of the portion la of the shell 1 and is connected by connectors to one of the control electronics 9 on the supporting structure 6.

The blower 2 and the louvers 7 are designed such that the blower 2 always promotes some air in the interior 3, which cools the electrical system, electronics, LED control electronics 9 and LED strips 20 and escapes through the louvers 7 back to the outside, to dissipate the heat loss.

The barrel-shaped portion 1a of the shell 1 may be composed of a plurality of radial segments 30, one of which is shown in perspective in Fig. 3 together with the LED strips 20 attached thereto. The segments 30 may be provided at their edges with zipper elements to connect them to each other or to the other sections 1b and 1c of the casing 1, which have corresponding zipper elements. The LED strips 20 are elongate flexible boards which are each equipped with many, preferably individually controllable LEDs 21 (FIG. 4B). LEDs with different colors such. B. Red, green and blue can be arranged alternately or in groups one behind the other, or the individual LEDs can be multicolored.

The barrel-shaped portion la of the shell 1 and the LED strips 20 form in the inflated state of the shell 1 a uniform round video surface, which can show 360 ° -Panoramabil-. After switching off the fan 2, the shell 1 can be broken down into their sections la, lb, lc or segments 30, which can be folded together to save space for transport and storage, without having to remove the LED strips 20 thereof.

Each LED tape 20 is carried by an approximately equally long elongated profile 40, which is shown in Fig. 4A individually in cross-section and in Figures 4B and 4C together with one in each case inserted LED tape 20 in perspective. The profiles 40 are made in this embodiment of sponge rubber, but may also consist of another more or less flexible material, which should also be electrically insulating if possible. The LED tape 20 is glued in this example in the profile 40, either directly or by means of double-sided tape, but may be attached to the profile 40 in other ways, for. B. by positive locking.

The profiles 40 are attached at short intervals next to each other on the shell 1 and on each shell segment 30 and are designed such that they hold the inserted into the profiles 40 LED strips 20 and thus their LEDs 21 at a defined distance from the shell 1 , wherein the main radiation direction of the LEDs 21 points in the direction of and through the casing 1. The LEDs 21 are those with relatively large radiation angles, and the distance of the LEDs 21 from the shell 1 is dimensioned with a few millimeters such that each LED 21 illuminates a spot on the shell 1, which is a much larger area than the emitting surface of the LED 21 itself has. The LED strips 20 may not be available in a height corresponding to the envelope 1 or the envelope segments 30. However, a plurality of commercially available LED ribbons 20, each supported by an equally long profile 40, may be connected in series by being connected together by ribbon cables 41 and connectors 42, as shown in FIG. 4C.

The profiles 40 are attached at short intervals next to each other on the shell 1 and the shell segments 30, as illustrated in Figures 2 and 3. The attachment could z. B. be an adhesive bond, but allow non-destructively releasable and reconnect fasteners to replace individual profiles 40, z. B. in the case of defect of an LED strip 20 therein. Some ways to attach the profiles 40 replaceably to the shell 1 are described below.

One way of non-destructively attaching and reconnecting the profiles 40 is shown in FIG. In the shell 1 blind rivets 50 are used at regular intervals, each carrying a clip 51 made of spring steel wire, which is bent so that the profile 40 with inserted LED strip 20 between two legs 52 of the clip 51 fits, where it is with a Angled ends 53 of the clip 51 looped rubber ring 54 is attached to the shell 1.

Another way to secure the profiles 40 non-destructively detachable and reconnectable, is shown in Fig. 6. For this purpose, textile strips 60 are sewn to the inner sides of the shell segments 30 of the section la of the shell 1 at regular intervals corresponding to the profile spacing, which are provided with hook Velcro strips 61 and loop Velcro strips 62, which are stapled behind the profiles 40, as shown in FIG 6 illustrated by arrows.

The textile strips 60, the Velcro straps 61, 62 and the yarn used correspond to the building material class AI, so that the connection of the profiles 40 with the shell 1 is fireproof. In Fig. 6 dashed lines and the Abstrahlkegel 22 of the LEDs 21 are located. The strong expansion of the Abstrahlkegel 22 and the radiation characteristic of typical wide-angle LEDs cause the projection of optically soft pixels on the envelope, whereby the viewer gets despite small gaps between the pixels the impression of a homogeneous video image.

Another way to attach the profiles 40 non-destructively detachable and reconnectable, is shown in Fig. 7. For this purpose, clips 70 made of spring steel wire are provided, which are slipped over the profiles 40 and have bent ends 71 and 72, which are pushed under seams, not shown, which are sewn at regular intervals on the insides of the shell segments 30.

For the production of each curved in two spatial directions sections la, lb, lc or segments 30 of the shell 1 textile webs are provided by means of a plotter with markers for the blank and for the placement of the profiles 40, cut and sewn together and then on a large table designed. The profiles 40 are fastened along the corresponding markings, with the LED strips 20 also being inserted therein. Thereafter, the individual parts can be rolled or collapsed parallel to the profiles and then transported to their mounting location, where they can be assembled with the zippers around the structure 6.

The shape of the profiles 40 for holding the LED strips 20 shown in Figures 1 to 6 is only an example, and other profile shapes may be used.

8 shows an example of a slightly differently shaped profile 80, which engages around an LED strip 20 in a form-fitting manner. Thus, the LED strip 20 is easily connectable to the profile 80, either by pushing in or by insertion in the longitudinal direction, and correspondingly easily detachable again.

The profile 80 shown in Fig. 8 also has no long continuous groove on the luminous side of the LED strip 20, as the profile 40 described above, but contains individual conical holes 81 for the passage of light, for each light-emitting diode one, wherein in the longitudinal direction between each two holes 81 a Mossgummisteg 82 remains.

A further embodiment shown in FIGS. 9 and 10 with regard to a further apparatus for displaying images or films has a further shell 101 with an alternative shell structure 185.

This alternative casing structure 185 is distinguished, in particular, by the fact that the further casing 101 comprises a total of a plurality of ring elements 186 (shown by way of example only), which are arranged vertically next to one another or, as the case may be, above and below one another, as shown in FIG.

It is understood that such a hitch connection can be constructively realized in a variety of ways. In this embodiment, a hitch connection with a number of connecting elements 187 is provided for this purpose.

In the present further embodiment, the alternative sheath assembly 185 comprises a total of four such ring members 186.

Preferably, the uppermost ring element 186 is fastened to a supporting structure (not shown here, but FIG. 1), which here is designed as an aluminum ring element (likewise not shown) or the like.

The ring element 186 arranged under the uppermost ring element 186 is then preferably fastened directly to this uppermost ring element 186, and so forth. In other words, the respective underlying ring element 186 is attached to the respective ring element 186 arranged above it.

Together, the ring members 186 then form the further sheath 101, which tapers from the upper end 101A to the lower end 101B.

Apart from the alternative shell construction 185, the further device shown in FIGS. 9 and 10 may have a similar interior to that shown in the figures 1 to 8 described device, which will not be explained again in connection with the further exemplary embodiment in order to avoid repetition.

Preferably, each of the ring members 186 is comprised of a plurality of longitudinally extending radial segments 130 which are concentrically disposed about the central axis 188 of the further apparatus.

Over each of the ring elements 186, a fiberglass fabric 188 is stretched, which is clamped in a groove (not shown here) on the side of the respective ring member 186. The clamping process itself causes the glass fiber textile 189 is stretched so that the fiberglass fabric 189 rests exactly on the LEDs, not shown here.

Power magnets (not shown here) are integrated on the sides of the radial segments 130. When all the ring elements 186 hang on the structure, the radial segments 10 are laterally merged and held together by the power magnets to the ring elements 186, whereby a total of the stable further shell 101 is formed.

Between the vertical ring elements 186 also still seals (not shown) are mounted such that the other device can be placed under atmospheric pressure, as already described above.

The lower spherical cap-shaped section (not shown here, but see FIG. 1) thus acquires its exact shape.

In the event of a fire, a fire protection system (see, for example, FIG. 1, extinguishing gas generator 10) can now be released an inert gas for displacing the atmospheric oxygen.

Another embodiment shown in FIG. 11 shows another apparatus for displaying images or films with another shell 201 composed of a total of 36 radial segments 230. These radial segments 230 are attached from radially outside to a suitably designed supporting structure 206 of the other device.

According to the illustration according to FIGS. 12 to 16, it can be clearly seen that the radial segments 230 in each case essentially consist of eight individual LED plate elements 290 (numbered here only as an example), which are arranged vertically in aluminum frame 291 of the supporting structure 206 are.

Over each of these aluminum frames 291, a textile part 288 is stretched.

Each of these LED plate elements 290 has an individual radius (not separately numbered) in the vertical direction or longitudinal extent of the radial segment 230, as specifically indicated in FIG. 13, these individual radii of the LED plate elements 290 arranged on top of each other for a better overview directly associated with each LED panel 290.

Here, the uppermost LED plate element 290A still has a larger width B 1 and a smaller height Hl in relation to it, while in the lower LED plate element 290B, inverse aspect ratios prevail, and the width B2 is smaller than the height H2.

Thus, the LED plate members 290 from top to bottom are always narrower, but built higher.

In a next embodiment illustrated in more detail in FIG. 17, a design variant with respect to a next apparatus for displaying images or films is shown with two aluminum profiles 391 arranged next to one another and adjacent to one another. The aluminum profiles 391 are in this embodiment up to 4 m long and curved. Hereinafter, the further structure of this construction variant is explained and numbered only in connection with the right-hand aluminum profile 391, since the construction on all other aluminum profiles 391 of this device is the same.

In the aluminum profile 391, which may be configured as an open or closed aluminum frame, a plurality of LED plate elements 390 are integrated, as already described above.

Each LED panel 390 includes radially outward a plurality of 10 mm SMD elements 390A (surface-mount-device), which are clad with a fiberglass textile portion 388.

The fiberglass textile part 388 is stretched with a tensioning device 392 tightly around at least two edges of the aluminum frame / LED panel unit.

Since the fiberglass textile part 388 may not be bent hard around an edge due to a risk of breakage, the edges are provided with a suitable deflection device 393, wherein each deflection device 393 structurally comprises simply a steel plate 393B provided with a rubber profile element 393A.

The rubber profile element 393A is rounded, so that the fiberglass textile part 388 with a sufficiently large radius, so gently, laid around this edge or stretched.

The steel sheet 393B is sufficiently strong and stable, and moreover stably inserted into the aluminum frame 391, whereby it holds the rubber profile member 393 A particularly accurately in position even when the glass fiber textile member 388 is stretched. As a result, it is possible for the glass fiber textile part 388 to be uniformly disposed on each of the SMD elements 390A or to be spaced apart from each of the SMD elements 390A.

The tensioning device 392 has, on a first side 391A of the aluminum frame 391, a clamp 392A, by means of which one end of the fiberglass textile part 388 bears against the Aluminum frame 391 is clamped. For this purpose, the clamp 392A has a steel sheet 392B screwed to the aluminum frame 391 and is therefore also of extremely simple construction.

The steel sheets 393B and 392B have, at least in this embodiment, a sheet thickness of 1 mm.

On the first side 391A opposite side 391B, the actual clamping mechanism of the clamping device 392 is arranged.

This tensioning mechanism comprises two threaded elements 392C (numbered only by way of example), which are screw-connected to one another by means of a threaded sleeve 392D with a left-right thread. One of the threaded elements 392C is screwed into the aluminum frame 391, whereby the Spannmechamsmus is fixed to the aluminum frame 391.

Further, the tensioning mechanism is equipped with a cedar part 392E in which the other end of the fiberglass textile part 388 is supported.

In the cedar part 392E, the other of the threaded elements 392C is screwed.

Now, when the threaded sleeve 392D is rotated in the corresponding direction, the cedar member 392E moves away from the aluminum frame 291 such that the fiberglass textile member 388 is stretched around the aluminum frame 391.

In the region of the joint 394 of the two illustrated aluminum frames 391, the adjoining fiberglass textile parts 388 immediately seal the interior space 303 of this next device.

Here, the fiberglass textile parts 388 are elastically supported by the rubber profile elements 393A at the butt 394. It should be explicitly pointed out at this point that the features of the solutions described above or in the claims and / or figures can optionally also be combined in order to be able to implement or achieve the explained features, effects and advantages of the invention in a cumulative manner.

It goes without saying that the exemplary embodiments explained above are only first embodiments of the device according to the invention. In this respect, the embodiment of the invention is not limited to these exemplary embodiments.
