Description

Flexible roofing

The invention relates to a device for roofing with means for opening and closing individual roof elements of this roof, in particular sidewalks, shopping areas, streets, traffic-calmed zones, busy places, restaurants, etc. The invention further relates to an advantageous use of the device.

Canopies in shopping streets or shopping arcades are particularly designed to protect against rain and thus promote sales. In general, these are complex glass-steel constructions, which are very expensive and are typically estimated at DM 3500 per square meter plus sun protection. In addition, such glass roofs with sun protection are very expensive to maintain due to the enormous cleaning requirements.

Static roofing is disadvantageously unattractive when the sun shines and then counteracts an increase in sales in neighboring shops.

From document EP 0 567 030 A2 an extendable cover is known in which several blinds are arranged one behind the other. Such a roof is admittedly considerably cheaper than the roof structures usually used in practice. However, the inexpensive, extendable cover only provides insufficient protection against rain, as water can drip between two roller blinds and frame structures and from here. It is therefore a pure shading system. In addition, the type of funding construction leaves little compared to the all-weather roof Wind chill too.

The object of the invention is to provide an inexpensive, all-weather roofing with which the passer-by and visitor frequency and thus the turnover in shopping arcades, shopping streets, pedestrian zones, squares, or at events and the like can be increased. The season for beer gardens and amusement parks etc. can be extended almost all year round (with infrared heating). Also, the table and chairs do not have to be wiped after every downpour, which saves personnel costs. At horticultural markets, spoilage of goods is reduced by over-watering or drying out.

The object of the invention is achieved by a device or a method with the features of the main claims. Advantageous embodiments result from the related claims.

The claimed roofing device has a plurality of retractable and extendable roof elements arranged one behind the other. The roof elements are therefore not arranged one above the other. The roof elements can be the roller blinds known from EP 0 567 030 A2. The roof elements can alternatively be in the form of blinds, which consist of a large number of slats.

A channel and / or a channel for draining rainwater is assigned to each roof element. This is to be understood to mean a channel or a channel arranged in such a way that the rainwater which occurs on the extended roof element flows into the channel or the channel. In particular, the gutter or the channel is designed in such a way that the rainwater reliably flows into the gutter or the channel even in strong winds.

The rainwater can be led from the gutter or the canal into a sewage system. There is an inexpensive canopy of any length available that opens when the weather is nice and at bad weather can be closed for the purpose of increasing sales. The rainwater can be fed directly into the sewage system, so that dryness under the roof is guaranteed when it rains.

In order to protect the means that extend and retract the roof elements against snow and rain and thus, for example, against icing, the roof elements are essentially housed in a housing of a means of transport in the retracted state. The means of transport is guided along rails and / or bars. Furthermore, the housing has the channel and / or the channel for draining rainwater. In this way it is achieved in a simple and therefore inexpensive manner that the channels or channels are moved together with the roof elements. This ensures that a channel or channel is assigned to each roof element. The rainwater that enters these channels or channels flows off laterally, for example into a further channel arranged laterally and parallel to the guide rails or rods. The water enters the sewage system in a known manner from this side channel.

The side gutter can form a unit with the guide rails or rods. The side gutter does not have to be installed separately. As a result, the time required for the construction of the roof is further reduced and thus cheaper.

A special feature of the invention is therefore to provide rain gutters or channels, which are moved along rails or rods together with the roof elements, in a simple and inexpensive manner. Vertical rain gutters are provided perpendicular to these sliding rain gutters for the transmission of the rain water to the sewage system.

The housing is essentially S-shaped in section. The lower part of the S-For has the gutter and / or the drainage channel for rainwater. The housing can thus be manufactured by simply bending a sheet into an S shape become. The manufacture is particularly inexpensive. At the same time, this configuration ensures that rainwater gets into the gutter even in strong winds and is not blown over the gutter. The space under the roof is therefore particularly reliably protected from moisture.

A roof element is preferably moved out of the upper part of the S-shape and fastened in the lower part of the S-shaped housing of an adjacent roof element. This ensures that rain and snow do not get into the area in which the means for retracting and extending the roof elements are provided.

Roof elements are preferably releasably attached. This is to be understood in particular to mean that no tools are required for fastening or loosening. The construction of a roof can be carried out particularly quickly and therefore inexpensively. Since the roof is usually arranged so high that it cannot be reached without aids, for example without a ladder, the attachment is protected against willful loosening. In addition, defective roof elements and the associated means of transport can be replaced particularly easily, quickly and therefore inexpensively. Cloth must be fixed to the sides of the shaft with screws or clamps so that the cloth or film winds up evenly and no wrinkles occur.

In a preferred embodiment, the device according to the invention has further lateral roof elements which are detachably fastened to the side next to the retractable and extendable roof elements, with a plurality of fastening positions arranged one above the other being provided for the lateral roof elements. The side roof elements are intended to create a roof to the entrances of neighboring shops. The side roof elements can be attached at different heights so that they can be attached at the same height as awnings that are above or at the entrances to the shops. This allows for proper drainage and stability of these awnings over the Connection to the gutters of the all-weather roof.

The lateral roof elements also expediently have channels and / or channels for draining rainwater.

If side roofs are provided on the roof, which extend to parts of the building, e.g. If awnings or canopies of the adjacent shops reach, the customer is even better protected against bad weather. This applies all the more if there is an interaction between the awning and the side roof in such a way that the two mesh with one another in the joint area so that rainwater or splashing water cannot flow down to the customer.

With a side roof that can be adjusted in height, it can be connected particularly easily and flexibly to the building to be connected to the roof according to the invention.

In an advantageous embodiment of the invention, the side roof has a rain gutter which is fastened in such a way that the extended awning of a neighboring store ends above it in the vicinity of the side roof. The side roof catches the water flowing off the edge of the awning and protects the area below this edge from water.

The device is preferably detachably connected to the floor and / or to adjacent buildings. Since the device is designed in such a way that it can be assembled and disassembled particularly quickly and flexibly, its area of application can be expanded by this configuration. A portable roofing is available, which is only installed temporarily. It is considerably cheaper and easier to handle than is the case with portable roofings according to the prior art.

The device is preferably connected to the floor with the aid of post elements, the post elements having predetermined breaking points. Moves For example, a car accidentally against a post, it is ensured that only the post, but not the rest of the roof structure is damaged. Since the device can be assembled and disassembled flexibly, it is particularly at risk since it must be able to cope with a wide variety of requirements. So it must also be suitable for particularly busy locations. The assembly and dismantling of maneuvering motor vehicles is also supported. The risk from such vehicles is correspondingly high. In the commercial streets and pedestrian zones, there is heavy delivery traffic with trucks and vans that already hit a prop when maneuvering.

If the device is fastened with the aid of post elements and each post element consists of at least two separate supports, a support can be damaged without the post element becoming inoperative. Even if, for example, a support of a post element is damaged by shunting traffic, the exchange can take place without hindrance without a lifting device. The aforementioned predetermined breaking points are then to be provided in both supports of a post element.

The post elements are detachably fastened with foundations. In particular, the foundations and post elements can be screwed together. For this purpose, a foundation has, for example, a sleeve with an internal thread. A post element has an associated external thread, which is screwed into the sleeve. Alternatively, for large supports, a threaded rod is cast into the sleeve of the foundation, which is screwed to the open threaded insert of the support (open due to the water drainage function). Threaded rod and sleeve must be made of stainless steel against corrosion. A locking means is also expediently available, with which the post element screwed into the sleeve can be locked. The locking element can be a bolt which is pushed through a bore which leads through the sleeve and post element. The Bolt is then protected from willful loosening, for example by a lock.

The screw connection ensures that the post elements can be adjusted in a simple manner, so that the roof can be mounted horizontally and optimally aligned even when the floor is uneven.

The device is made of lightweight construction, preferably predominantly made of aluminum and / or plastics, and / or is designed as a tensioning structure to facilitate assembly, dismantling and transport. This guide is particularly suitable for running areas that have no buildings along the roof.

If the roof is portable, you can react more flexibly to structural changes in the environment. A portable roofing also has the advantage that it can also be used where economic, legal or political reasons have so far prevented the construction of a fixed device. A mobile canopy can be used seasonally / for a short time and in particular can be leased for a certain time and is therefore easier to finance.

The roofing is advantageously opened starting from the center of the roofing, a sealing strip preferably being provided in the center. As a result, the roof can be opened particularly quickly and then closed again accordingly.

In particular, spring shafts for winding up the roof elements are provided which exert a tension force on the roof elements, the tension forces exerted continuously increasing or decreasing from roof element to roof element. The roof elements consist, for example, of a cloth or a film that are rolled up. So these are blinds. The spring shafts are used to enable the roof to close evenly interpreted differently. The person skilled in the art can determine with a few experiments how the individual clamping forces are to be designed in order to be able to smoothly close or open the roof.

For safety reasons, the tensioning forces for winding the roof elements are designed in such a way that the roof can be opened solely on the basis of the tensioning forces exerted.

In the closed state of the roof, the individual roof elements are preferably only partially extended. The total length of the fully extended blinds therefore exceeds the length of the path that is covered. To ensure that each roller blind is extended evenly when the roof is closed, the tensioning forces of the individual spring shafts must be designed to differing degrees. If the roof is closed towards the middle of the path, the spring shafts located at the ends of the path are to be designed the weakest. The spring shafts, which are in the closed state at the middle of the path, exert the strongest tensile forces.

If the roof elements are not fully extended when closed, there is a reserve that can be extended in the event of gusts of wind. Damage caused by gusts of wind can thus be avoided better.

The roof elements can consist of an awning fabric, a tarpaulin, a fabric or a blind. The lateral roof elements consist, for example, entirely or predominantly of glass, solar cells or plastic.

The demanding roof elements can be retracted or extended along a circular path. The awning fabric, the tarpaulin or the fabric of the roof elements then resemble a triangular shape. In such a case, a central post element in the middle of the device is sufficient. The outer rails are then held by means of a bracing that starts from the central post element. This embodiment is preferably used to cover Marketplaces.

Lateral coverage is achieved by vertical shutters, blinds or roller blinds. The device is then like a tent when the roof is closed.

The roof elements are preferably heated. For this purpose, wires that can be heated by current are worked into a film or lamella of the roof elements. Control means are preferably provided which cause heating or heating when a temperature below 0 ° C. is reached, for example at -1 ° C. In addition, the roof can be heated by infrared emitters or by fine heating wires (car rear window) incorporated into the cloth / foil / slat.

For safety reasons, blocking agents are expediently provided which block the entry or exit of unheated roof elements when a temperature below 0 ° C, for example -1 ° C, is reached.

To further promote sales of goods and services, monitors are housed in air-conditioned and / or watertight housings with a matt, anti-reflective tempered glass screen. These are attached below the roof or on the side of posts or poles. In the operating state, the monitors are moved out of the housings when positioned below the spring-wave train stations. The monitors can be used to advertise the products that can be bought in the adjacent shop. The monitors are connected to the Internet so that a single shop owner or article manufacturer can flexibly arrange the optimal advertising quickly. A business owner (e.g. advertising agency, article manufacturer, broadcaster etc.) can then easily and inexpensively carry out or exchange the desired advertising with the help of a standardized communication medium. In one embodiment, the monitors are protected by tempered glass if they are in an operating position. In particular, frosted, anti-reflective armored glass is to be provided in order to reduce glare.

Motor-driven spring shafts for retracting and / or extending the roof elements can be provided in order to be able to improve and control the opening and closing of the roof and to tighten the cloth on larger surfaces with larger shaft distances.

Emergency pillars, which are preferably monitored by cameras, are preferably installed in post elements. An emergency or rescue service can use the cameras to get an immediate picture of the current situation. Unauthorized use is also counteracted in this way, since cameras act as a deterrent in such cases and record the user on video.

The device is used in particular for the roofing of shopping arcades, shopping streets, streets with a large number of adjacent shops, public places, outdoor events, marketplaces or pedestrian zones, DIY and garden centers, parking lots, sports and football stadiums, amusement parks etc.

If the device according to the invention is used as a roof for a shopping arcade, shopping street, street with a large number of adjacent shops, public space, at open-air events or in pedestrian zones and the like, its attractiveness is increased by opening the roof in good weather and by rain or unbearable sunshine the roof is closed. This means that the shopping arcade can be used without any problems when it rains, without having to do without the sun to a tolerable degree when the weather is nice. The result will be an improved use of the shopping arcade. Sales will increase accordingly. The same applies if there is a path between a parking lot or a parking garage and one Department store or shopping center is covered with the sophisticated device.

The roof construction provides space to which advertising media can be attached. In a shopping arcade, shopping street, pedestrian zone and the like, such a space is very limited. By providing these additional advertising options, sales in a shopping arcade are further increased.

The increase in sales also succeeds because the products can be offered directly at the sales location. An advertising success can therefore be directly linked to the purchase of the product. It is therefore ^' an advertisement with the lowest scattering loss that is possible to date.

The roof elements advantageously consist essentially of windable surfaces. Advertising media are also fastened so that they can be swung away from the roof elements.

Due to the possibility of winding, the individual roof elements can be arranged one behind the other. It is therefore no problem to provide such a roof for long shopping arcades and streets etc.

In one exemplary embodiment, mutually displaceable struts are provided which are connected to one another via an awning-like surface, the struts serving as cross members for the awning surface in the extended state of the roof and preventing it from hanging down. This allows the substructure to be largely free of cross members and thus visually easier to design, since rigid cross members can be dispensed with.

If the struts serving as cross members are arched, rainwater can flow off to both sides of the surface, in particular into a gutter box, causing puddles to form on the surface and sagging of the surface is prevented. The arch shape is advantageous because it improves the statics of the struts, ie the struts can be constructed lighter and are still able to carry snow and wind loads.

According to an exemplary embodiment, an inclined support is provided on the device below the parking position of the struts for the unpunished surface which is normally sagging there. Therefore, it does not hang into the free space, which can reduce the height of the construction in a cost-reducing manner.

According to one embodiment, the device can optionally in resting or Operating position can be brought by means of ropes, timing belts or chains, which eliminates the laborious, manual process of the individual struts or awning boxes. In particular, this enables weather-dependent, fully automatic operation of the roofing device, also in order to avoid weather-related damage.

Roof-like covers for the rollers, guide rails and the retracted awning reduce maintenance and repair costs and protect the more susceptible components against the weather.

Pipes as guide rails are particularly inexpensive because they are commercially available. If the guide is formed by two tubes running parallel to each other, the awning boxes or struts can be fixed around five axes with minimal effort.

A special derailment-proof and tried-and-tested guide can be realized from mutually aligned rollers which grip around the guide in sections or rest against it. If the running surface of the rollers is made entirely or partially of plastic, rubber or a comparable noise-reducing material, the noise pollution for residents and passers-by when moving the roof elements is reduced. A two-stage drive on the one hand ensures that the roofing device is extended quickly and then enables the awning surface to be tightened forcefully to prevent known phenomena such as vibrations, fluttering and puddles on the surface.

If the individual support elements serving as crossbeams are moved on the guide by pulling them onto the surfaces, the surfaces are well tensioned to prevent fluttering and puddles.

In an advantageous embodiment, the device according to the claims comprises one or more cleaning agents, in particular a brush and / or a sponge for cleaning and drying the surface that can be wound up, the cleaning agent being arranged in particular adjacent to the means for winding up the surface below and / or above the surface that can be wound up is. With this configuration, the costs for cleaning the surface that can be wound up can be considerably reduced. This applies in particular if the cleaning means is arranged adjacent to the means for winding up above and / or below the surface that can be wound up, since the surface that can be wound up is then cleaned each time it is rolled up or rolled out.

The cleaning agents can be resiliently fastened so as to ensure a uniform contact pressure with respect to the surface that can be wound up and thus a uniform cleaning thereof. A cleaning agent preferably extends over the entire width of a surface that can be wound up, so as to clean the entire surface.

Manual cleaning is not necessary. Only the cleaning device has to be replaced within 3 to 4 years. The cleaning device is therefore preferably detachable, that is, interchangeably connected to the rest of the device. The coiled surface is also regularly freed of coarse particles that the durability is also significantly increased. An attractive look is guaranteed.

In a further embodiment of the invention, infrared heating devices are provided which can heat the space located under the roof. In cold weather, the attractiveness of a shopping area and the like can be further increased.

In one embodiment, the all-weather suitability of the roof according to the invention is ensured in particular by providing gutters which can be moved together with individual roof elements. Furthermore, the rain gutters are integrated in such a way that the water running off a sloping roof cannot be blown over a rain gutter arranged at the end of the sloping roof and can thus penetrate into the covered space. The aforementioned S-shaped configuration of a housing represents an example of how the aforementioned effects are achieved.

The advantages and advantages of the all-weather roof according to the invention are:

- Protection against precipitation such as rain, snow or sleet, protection against excessive solar radiation with negative effects on human well-being and health,

- unlimited outdoor experience in dry and pleasant weather conditions, since the roof can be opened over any length (10 to 100 m and more) without the static elements being present above the heads of the passers-by,

Visitors, guests and customers stay in the rainy weather,

- The construction is very flexible and can be built very delicately. The invention is suitable permanently as a roof for pedestrian zones, commercial streets, marketplaces, passages, parking lots, sports facilities and stadiums such. B. football u. Tennis stadiums, swimming pools, playgrounds, leisure and. Adventure parks, zoos, beer gardens and other outdoor dining, outdoor areas of construction and Horticultural markets or private households (terraces and swimming pools).

Use for briefly lasting events is possible with a mobile lightweight construction system designed according to the invention. Such events are e.g. E.g .: fun fair, junk u. Fairs, open-air concerts, open-air sports events or trade fairs (outdoors).

The economic background arises for the above. commercial users as follows. Yield of the above Sectors are very dependent on the weather conditions.

In rain, sleet and. too strong, unpleasant solar radiation, the turnover is extremely reduced by the absence of customers, visitors and guests. By using the all-weather roof according to Eifinduigs, weather-related losses in sales are generally excluded and, because of the location's weather independence, a significantly larger catchment area is opened up and the outflow of purchasing power into the greenfield shopping centers prevented for inner-city trade, due to the now very good mobility of households is at least 50%.

A short to nnttelftistliche doubling of customer and Turnover is already assessed very conservatively. Records from companies in the above industries can confirm this. A doubling of sales leads to a tripling of profits on average due to the high fixed cost block. Catering establishments do not have to wipe their tables and chairs dry after every downpour. The outside area, which is inexpensive in terms of mead costs, has a much higher guest frequency and a three times longer season.

For construction u. Horticultural markets mean that, in addition to significant increases in sales, the use of the roof means lower costs for watering the plants in summer, less spoilage of goods due to rain (overwatering) and sun (drying up of the

Flowering goods despite irrigation).

The comparison to previous static roof systems and shading systems is as follows. Previous roof systems are not suitable for opening free of large areas and to ensure rain protection and shading functions. This also means that previous roof systems are not suitable for optimally adapting to almost all weather conditions. When it rains, the all-weather roof offers passers-by protection from moisture. If the sun is too strong, well-being and protection against unhealthy UV rays are significantly improved. But even in pleasant, dry weather, the full convertible experience is absolutely guaranteed thanks to the movable roof elements and the filigree support structure, which is made possible by the flexibility of the roof.

With previous roof systems, pedestrian zones could generally not be roofed over, since closed roofs and roof systems with static struts did not ensure rescue and fire fighting with ladder vehicles on the upper floors of the adjacent buildings. Therefore, a really sensible roofing of the pedestrian zones has so far failed due to the requirements of preventive fire protection.

The all-weather roof according to the invention is, because of its flexibility and uncomplicated basic construction, considerably cheaper to manufacture and offer than conventional fixed roofs made of glass (because of the necessary light transmission) with sun protection, which, however, does not have a large area Allow opening.

The entire construction of the all-weather roof according to the invention is as

Modular principle (4 to 10 assembly modules later) can be produced in series. With the pre-equipped additional possible function options, it is much quicker and easier to set up compared to the prior art, as well as later

Can be upgraded, serviced and repaired at the right time. Therefore, for construction, repair and. Use maintenance work without further training.

The all-weather roof according to the invention has various rain drainage devices and functions that cross and u. Longitudinal channels and Falkohrstützen be shown. This is the only way to guarantee extensive rain protection.

Due to the possible filigree construction of the all-weather roof according to the invention and the pre-assembled module assembly, the system is mobile and can therefore be leased and can also be used very well as lightweight construction (aluminum-plastic) at time-limited events.

No previous roof system, not even glass roofs with sun protection devices are so versatile and usable in almost all possible weather conditions. as flexible as the all-weather roof. Glass roofs look like firing glasses when the sun shines, which leads to a greenhouse effect and makes additional sun protection devices indispensable. In the case of glass roofs with sun protection systems, the passerby still does not have the feeling of the open air on days with beautiful open weather, as is ensured by the almost completely movable roof surface in the all-weather roof according to the invention. With previous sun protection systems (without a fixed glass roof) this would perhaps be possible on small areas for pure shading. However, the known systems cannot be used in the event of precipitation or more than 3 wind speeds.

Glass roofs with sun protection devices must be cleaned and the Sun protection systems can also be serviced. Therefore, the follow-up costs are between 20 and 30 times higher than those of the Ali weather roof according to the invention, depending on the location.

The spring tension shafts connected to each other in one embodiment ensure a cloth or roof stretched evenly over large areas in order to be able to absorb wind loads of at least 85 tan h and heavy rainfall (rain and snow).

The all-weather roof can be used due to its filigree statics in pedestrian zones, inner city areas, parks etc. without disturbing or devaluing the grown overall picture.

The all-weather roof can be a flat-Schett roof, vaulted roof (approaching from both sides), semi-vaulted roof (e.g. approaching a facade from one side), saddle roof (approaching from both sides), one-sided pitched roof (can be moved like a half-vault) and larger Umbrella can be constructed with one or more supports in a round (flat or conical), rectangular or square shape. In addition, the all-weather roof can also be used vertically, which means that tent-like closed tent functions can be created. Domed and semi-arched roof structures can also be moved from the ground. Instead of cloths, foils or other fabrics, roller shutters, slats made of plastic, sheet metal (aluminum, metal, etc.) can also be used.

Further functional options in connection with the all-weather roof according to the invention are:

Area lighting above linear luminaires mounted along the longitudinal ledges and illuminating the roof surface, which serves as a reflector. The lighting can be dimmed to suit the lighting conditions using a lux meter, which ensures optimal, stimulating lighting conditions at all times. Lamps or torches on the respective supports of the all-weather roof construction replace today's lanterns (as dimmable above), without which lighting is not possible when the roof is retracted at dusk and in the dark. Due to the optimal lighting conditions at all times as area light, the mood of passers-by can also have such a positive influence on bad weather conditions (gray rainy days have a depressive effect) that they no longer freeze, are in a good mood and are encouraged to linger, consume and consume.

Electronic roof control with all subordinates are designed and programmed in such a way that the following sensors can be used at the same time: Wind monitor extends the roof from 8 wind speeds or no longer; Frost monitor lets the roof retract from -1 ° C or no longer extend; Rain monitor with heating and adjustable time delay lets the roof extend when it rains and retract when it stops; UV u. Luxsensor lets the roof extend as sun protection if certain, set UV or Lux values are exceeded and retract when the values fall below; Infrared sensors, vibration detectors and pressure bars on the first, approaching wave boxes have protection and monitoring functions, with unauthorized access to the roof and possibly TV and. Emergency systems are interrupted by these facilities, the roof function, video surveillance with connection to the police, security guards and. Fire brigade is activated as an alarm. A manual unlocking for retracting the roof in an emergency is possible in one embodiment when electrical control is no longer possible, which is very safe, simple and easy, for example, by using spring shafts. works automatically.

Emergency rafters on the supports of the roof are preferably mounted or integrated with a dedicated line to the police, fire brigade or even security services as known from highways. Infrared surface and Gas radiant heaters with and without fans for heating below the roof on and under the transom structures or supports are preferred.

Irrigation above the roof by hoses, tubes made of stainless steel, aluminum or plastic with outlet nozzles (e.g. car washes) mounted on the spring shaft housing can be provided in order to cool the temperatures below the roof down by up to 6 ° C on hot days.

A cleaning bar can be mounted on or in the spring shaft housing and, for example, each with a fine brush and. Be provided with a sponge strip. From below and above, two such strips can be connected to one another via springs mounted on the side, in order to enable simultaneous, double-sided self-cleaning of a cloth each time the roof is moved. A sponge strip can be used for drying.

A camera for video surveillance in the event of unauthorized access to the system and its systems, for orientation and localization of the location of use for the police or fire brigade after the emergency call has been made can be provided. A TV system (monitors, flat screens, projector devices with sound reinforcement on the roof supports, in front of spring shafts installed below the roof or between the respective roof supports on separate holding devices below the longitudinal bars) for broadcasting an advertisement controlled via telephone line, cable, satellite, Internet in combination with further regional u. National TV content for the mass advertising of products directly at the sales location can be provided. This means that for the first time there is practically no more wasted coverage, which is now possible through integration into the all-weather roof according to the invention and without which municipalities in the commercial streets and pedestrian zones could not be approved until now due to visual design ideas (design and monument area statutes). Variable in height, at. Longitudinal bar construction on the side, outside glass roofs with gutters and Rain drainage functions for the Falkohrstützen of the DacWtonsttuktion ensure the roof to adjacent shops, etc.

Solar collectors or solar cells can be provided, for example, discreetly to the side of the longitudinal ledges and / or above spring shafts or instead of glass panes, in order to enable a location-independent power supply.

In the following the invention is explained with reference to drawings and shows

1 consists essentially of longitudinal beams 4 and perpendicular to it, serving as a stiffening element, cross members 2, which are connected to each other like a frame and rest on posts 1 at a height of 2 to 6 m and more. In the exemplary embodiment, the frame formed from the supporting elements 2, 4 covers an area of 5 × 10 to 40 and more meters. A roof surface with the corresponding number of square meters causes considerable wind forces, in particular buoyant forces, which is why the posts 1 must accordingly have foundations that are not shown. The prefabricated foundations already mentioned above or the tent-like bracing can also be used. Along the longitudinal beams 4, on the inside, not shown in detail, serving as filling means, for example rails or tubes, are provided. The awning carriages 20, which are guided on rollers 32, can be moved along this along the longitudinal members 4. The awning cars 20 are each connected to one another by a piece of awning fabric 9 which can be rolled up in the respective awning box. Thus, if the distance between two awning carriages is increased, the awning fabric 9 stretches between them and thus offers sun or rain protection. For the sake of clarity, the left part of the awning 9 is shown in a transparent / broken line. An advertising medium 48 is attached below and adjacent to the canopy. Alternatively, monitors and advertising media can be mounted on the supports and below the longitudinal bars and cross bars.

In the embodiment shown in FIG. 1, a side roof 7 running along both sides of the pergola construction 8 is also provided along the longitudinal beams 4. This can serve as an interface to neighboring houses or other free-standing sales stands, for example. In order to maintain the airy character of the pergola construction, the side roof 4 is in the form of a Glass construction executed. The side roof also gives the construction a more pleasing, more widespread appearance.

The side roof can also be designed differently than shown in FIG. 1. For example, essentially consist of two elements, namely a glass pane running downward from the longitudinal member 4 and a side roof 7 which adjoins the lower edge of the glass pane in steps. The side roof 7 can also be provided in a different manner below the side member 4. Rain drainage (not shown) along the bottom edge of the side roof is advantageous. On-site installation is also made easier if, as described above, the height of the side roof is variable to the existing building, e.g. an awning that can be customized.

Another rigid, preferably made of glass roof structure 5 is provided in the area of a so-called station 6 for the awning boxes 20. A station is understood to mean the area in which the awning boxes are parked in the rest position if the roof made of awning fabric 9 of the area under the pergola construction is not desired, for example when the weather is nice, but also in bad weather with wind speeds that are dangerous for the construction can be. It is therefore expedient to protect the awning boxes 20 located in the station 6, which are in the rest position, with the awning fabric 9 rolled up to the maximum by the roof 6, reference being made to FIG. 5 for an explanation of the rest position. The transparent nature of the awning fabrics creates an outdoor feeling, unlike rigid roofs.

2 explains the guidance of the awning boxes 20 on the side member 4. The side member 4, which is to be designed according to the rules of statics, since it has to pass on the considerable part of its own weight but also the wind loads to the posts 1, adds one internally directed, horizontal running tube holder 11. This can be formed, for example, by providing tube pieces at certain intervals. It is also conceivable that Provide holder 11 in the form of a continuous plate connected to the longitudinal member 4. In the exemplary embodiment 11 Ro pieces are provided as the tube holder, which holds the tube 10, which has a larger diameter than the holder 11, at regular intervals. Two impellers 32, which are directed towards one another in the wheel arch 30 via wheel shafts 31, guide the awning box 20 connected to the wheel arch 30 via the wheel arch fastening 33 and along the running tube 10. It is important that the guide, which in this exemplary embodiment is formed by rollers, is in a position is to absorb both the weight forces of the awning box 20 with awning 9, as well as the buoyancy forces caused by wind in the opposite direction and the horizontally acting forces generated in the same way and to transmit them to the pergola construction. For this purpose, the rollers 32 are profiled in such a way that they partially abut the running tube 10 and both rollers 32 act comprehensively on the running tube. The wheels 32 are advantageously ball-bearing.

The wheel housing 30 or the awning housing 20 can be moved along the guide 4 via pull ropes or chain drives. In the exemplary embodiment, 30 cable fastenings 36 are provided on the wheel arch 30 for this purpose. Embodiments are conceivable in which all of the awning boxes are connected to one another by a rope, the first box pulling the following, only the first leading awning box being pulled from the rope and the remaining boxes being moved via the pull exerted on the awning fabric or each Awning box is pulled individually from the rope, which results in a particularly good tensioning of the awning fabric.

The chain or rope can either be designed as a motorized train (windable chain / rope) or according to the endless principle (cable car principle: circulating rope / chain). A chain drive is preferable to a toothed belt, as it is more stable and can exert a higher tension. In order to protect the mechanical guidance against the ingress of dirt and moisture causing interference, a cover 13 made of stainless steel sheet is provided, which is fastened to the top of the I-shaped side member 4 and covers the wheel arch 30. This cover advantageously extends to the top of the housing 21 of the awning box 20, the connection being able to be additionally sealed, for example by a web or sealing system, against the ingress of moisture. The cover 13 explained is particularly useful when the awning fabric is extended during windy bad weather conditions, since it makes it more difficult for the water to flow away laterally at the edge of the awning with subsequent dripping onto the floor.

Fig. 2 also shows an analogous to the cover 13, but provided on the underside of the longitudinal beam 4 gutter box 12, which on the one hand hides the guidance against glances, that is advantageous from an aesthetic point of view and on the other hand as a rain gutter for draining from the awning box 20 from Awning fabric 9 collected, rainwater is used. The water collected in the gutter box 12 can e.g. can be dissipated via the post 1.

3 explains the structure of the awning box 20, which is inexpensively formed from an S-shaped aluminum or stainless steel housing. The box is delimited by the wheel housing 30 on the two end faces, as shown in FIG. The upper housing space 22 contains a spring shaft 24, which extends over almost its full length and is under spring pressure, on which the awning fabric 9 is partially wound. The awning fabric 9 can be pulled out of the housing to the right, the spring-loaded shaft exerting a force which pulls the fabric into the interior of the upper housing space 22. A protective web 26 integrated into the housing 21 in the area of the outlet, which is formed by angling the upper housing edge, protects the wound awning 9 against dirt and moisture. The awning fabric 9 leaving the upper housing space 22 has a slight slope in the direction of the not shown further awning box 20 and drains rainwater in its direction.

The further, not shown, awning box is structurally identical to that shown in Fig. 3. Accordingly, the awning fabric 9 coming from the spring shaft 24 is connected to it as shown in the lower housing space 23 in FIG. 3. The awning fabric 9 of an adjacent awning box is fixed to the rigid holding shaft 25, and it is not intended to roll it up. The function of the holding shaft is only to pull the fabric 9 out of the upper housing space of the adjacent awning box when the distance between two awning boxes 20 is increased.

For maintenance reasons and for assembly purposes, it is expedient if the connection in the region of the holding shaft 25 can be released by simple measures. It can also be seen that water collected by the left awning fabric 9 in the. flows lower housing space 23, is held in the end web 27 in this and finally, as indicated in Fig. 2, is passed into the channel box 12. A symmetrical or asymmetrical gradient must be provided for this. The acceptance of such a roofing system in bad weather depends in particular on the fact that no water escapes at places not intended for it and hits the visitors.

4 shows two hamper boxes 20 connected to one another via inclined awning fabrics 9, the cover 13 of the running tube 10 with the wheel housing 30 running on it.

Fig. 5 illustrates how the awning boxes 20 are parked in the so-called station 6 under the roof 5 in the rest position. The individual boxes 20 are connected to one another via the awning (not shown here), but are at a minimal distance from one another. The position of the awning fabric 9, which it occupies in the park position, determines in particular the S-shaped geometry of the housing 21 of the awning boxes 20, with wear Significant friction between the awning and the housing edges when retracting and extending is to be avoided. ^/

Fig. 6 finally shows a side view of the wheel housing with the four profiled impellers 32, which partially enclose the running tube 10 and thus achieve the horizontal and vertical fixation. It is essential that the awning box is only movable in one axis and is fixed in five axes (degrees of freedom). The position of the housing 21 and the two shafts 24 and 25 is shown in dashed lines.

There are numerous possibilities for improving the utility value of the roofing according to the exemplary embodiment explained above. The system can be controlled fully automatically using UV, rain or other standard environmental sensors. In particular, wind and storm guards prevent the roof from being destroyed. Vibrations and forces acting on the device, e.g. B. by vandalism, earthquake or fire, are recorded by force sensors, the signal can be used for roof control (retracting), for video recording and recording and for alarming security forces. Networked information terminals can be attached along the roof, which are available to passers-by for general information, but also for advertising and maps. This increases the time spent in the shopping area and the passer-by is made aware of other offers. In the event of emergency calls, a video connection to the called party can be established automatically in the control center. The head office can get a better picture of the situation.

Further control options are possible manually or electrically, also via remote control or lockable switch boxes, in particular at the so-called train stations 6. Safety aspects, for example for emergency services, are also taken into account, such as manual decoupling of the individual awning boxes. Means for air conditioning, such as fans or IR radiators, can be provided in the area of the pergola or awning boxes the attractiveness of the facility with the adjacent shops is further increased in the cool season. As a result, the open-air season can be extended and space can be used more effectively.

The mechanics, e.g. the roll-up mechanism of the spring shaft, the transport rollers and the rain gutters should be heatable (e.g. by means of heating loops, trace heating, radiators, warm air or exhaust air from adjacent shops and underground car parks) to ensure trouble-free operation in winter.

The system can be operated autonomously from the existing energy supply if solar cells, in particular partially translucent, are provided on the roof surfaces 5, 7. Heat exchanger, e.g. B. thermal solar systems can be provided on the device and the side roofs, in conjunction with a heat storage, also in the form of global warming, to absorb heat in the warm season and to emit it in the cold season in the upper layers of the floor for walkway heating CO2-free ,

At dusk or in the evening, special lighting effects can be achieved by not illuminating the area directly by lights 3, but indirectly by spotlights directed towards the awning fabric. With a bright or colored awning fabric, also in connection with color emitters, special stimulation effects can be created.

Further possibilities result from the fact that video surveillance and / or sound reinforcement (also for advertising messages) can be provided along the system.

The aforementioned advantageous configurations also apply to the second exemplary embodiment described in FIGS. 7-10.

The pergola construction 8 in FIG. 7 essentially contains all the elements described in FIG. 1, which is why only the differences are described. In the area of the so-called station 6 below the roof 5, a plurality of adjacent struts 40 are shown in the rest position. These are connected to each other via a piece of awning fabric 9, which is not shown and is approximately 3 meters long. In the embodiment shown in Fig. 7 rest position of the awning fabric between the struts would be about sag 1.5 feet downwards, and therefore a grid-like inclined ^• Support 41 is provided below the parked struts 40 that the sagging awning fabric during retraction of the struts in the station fold out of the horizontal. The awning fabric is not shown in FIG. 7, which is why reference is also made to FIG. 10. An advertising medium 48 is attached to the inclined support, which is then inclined as desired relative to the vertical.

The inclined support 41 is preferably an open lattice structure, on the one hand in order not to oppose the airy effect of the pergola construction and on the other hand to facilitate drying out of the awnings placed thereon.

When the struts 40 guided along the running tube 10 by the running gear 35 are moved out of the station into the clamping position, the awning fabric 9 connecting the struts tightens like a barrel vault, since the struts have an upward arch shape. As a result, rainwater runs off on both sides of the awning fabric 9 in the direction of the channel 12 shown in FIG. 8, which ends in a post 1 of the pergola construction.

FIG. 8 also shows the undercarriage with four wheels 32 arranged in the same plane to one another in the same plane, which act vertically on the running tube 10 from both sides, reference being made to the first exemplary embodiment. Additional horizontal fixation of the wheel unit is achieved by two horizontal wheels 34, which are perpendicular to the impellers 32 in one plane. Such guides are e.g. known from roller coasters and conveyor technology.

The drive options of the struts by means of ropes or chains are to be assessed in exactly the same way as in the first exemplary embodiment.

REPLACEMENT SHEET (RULE 26Y FIG. 9 explains a particularly effective way of tightening the awning fabric 9, in particular with the proposed dimensions of the awning fabric. Via the drive mechanisms already known from the first exemplary embodiment, the awning fabric is brought approximately into the end position when the awning is extended, the strut 40 which is furthest away from the station 6 being provided with a plurality of catch hooks 43 which engage in a tension strut 42 provided at the end position are determined. In order to bring about the tightening, a powerful drive moves the tension strut in an arc upwards and backwards and thus exerts a greater force than the extension device designed for longer transport routes. There are therefore two drives: a first for the long travel to the end point and a second with a short travel for tightening the awning fabric.

A first and a second drive are understood to mean that two separate power sources transport or perform the tightening tasks. According to the invention, this also means that an energy source fulfills both tasks, for example by means of a transmission. It is essential that one mechanism for transporting the awning and another for tightening the same is provided.

The large area of the roofing device according to the invention is particularly suitable for applying advertising, also on the awning fabric, e.g. B. by printing or light projectors.

The pergola constructions described above have a particularly light effect in that, apart from the train stations 6 or end points, no cross members are provided. The stability of the awning fabric is achieved either by the awning boxes 20 acting as movable cross members or by the struts 40.

REPLACEMENT SHEET REGEt26) The cost of installing such a canopy z. B. in pedestrian zones and public traffic areas can be financed from the resulting creation of additional sales areas in the area of the awnings or side roofs, from advertising, from renting video surveillance positions to security companies and from the connection to Internet services.

In the exemplary embodiments, the longitudinal beam 4 is designed in the form of an I-profile. Instead of this, a truss construction is also possible, which has an aesthetically lighter appearance and, due to its lower weight, gives the possibility of saving additional posts 1.

The invention is not limited to the pergola contraction described with posts at all four corner points. It is essential that a frame with guide rails - including curved ones - is created. This can e.g. B. can also be held at one end of posts and at the other end by a pull rope construction or carried like a suspension bridge by one or more central posts.

Alternatively, constructions are conceivable in which the guide runs obliquely / arcuately, with this at one end, for. B. is stored in the ground in a foundation. In the rest position, the extendable transport means / struts are stored in a lower section and are extended upwards along the guide via a driver. Retraction is particularly easy if the means of transport / struts can slide back into the rest position by gravity (emergency retraction).

The invention can be used particularly flexibly, since it has a modular structure (awning box 20 or struts 40). This also applies to the pergola construction, which can be modularly built up next to one another and at an angle to one another, and this means zones of any design and distances of any length against weather protects. Protecting the population from the harmful UN rays of the sun in particular will continue to gain importance.

The device described is suitable for fastening lighting, air conditioning, video surveillance, public address, advertising, emergency call devices, etc. Since numerous posts are usually provided for this purpose in the urban area anyway (light poles, solar poles, sign poles, etc.), take the posts of Covering only a small space, since the previously mentioned holding masts can be omitted. Cable ducts are also relieved, since empty pipes can be provided.

The invention can also be used in football stadiums, sports arenas, etc. for temporary grandstand roofing and solves the known problem of shading the lawn area, which receives hardly any vital light, with ever higher and narrower grandstands with a roof.

FIG. 9 in conjunction with FIG. 10 shows that the tightening of the surface 9 can be carried out particularly effectively if a tensioning strut 42 is provided on each side and acts on the two ends of a row of struts 40 / transport means 20 connected to one another, because the system's own friction can be overcome better and therefore the grading is improved.

The individual figures also show the attachment of advertising media 48, which can be arranged, for example, to be pivoted away to the side.

The individual features of the two exemplary embodiments discussed can be combined with one another and understood as alternatives.
