Description

 Roofing device

The invention relates to a device for roofing, in particular of sidewalks, shopping areas, streets, traffic-calmed areas, busy places, restaurants, etc.

Numerous devices are known for protecting the aforementioned areas against weather influences, e.g. Umbrellas, tension sails, awnings and permanent roofs:

1. Umbrella systems are easy and flexible to use, but only cover a comparatively small area. In addition, there is a high susceptibility to wind and a disturbing drainage of rainwater into the area to be protected against weather. Parasols are therefore primarily an island-like protection against the sun and can only be used to a very limited extent in the rain.

2. Tension sails are a common sun protection in streets and squares in Mediterranean areas. Large-scale cloths, comparable to sailing, are guided and stretched on lines or pipes by means of ropes. The large surfaces of the cloths generate large wind forces on the support structure and ensure unpredictable behavior of the cloth surface, especially due to flutter and wave-like beating. In the event of precipitation, the cloths sag and puddles form in the depression, which collect further precipitation and therefore represent a considerable mechanical load. Rainwater drainage remains problematic when the sails are tilted. Tension sails are therefore primarily sun protection for squares and streets with slight air movement.

3. Awnings are cloths unwound from a roll, which can be wound onto it, the one end of the cloth protruding outwards and arms held on a wall. The large fabric surface and the often long lever arm make the awning extremely susceptible to wind and rain. The easy-to-implement arm construction is not suitable for stretching the awning fabric, which is why sinks form for the rain with a corresponding load on the lever arm. The water flows from the lower hanging edge of the awning towards the floor and creates puddles and water splashes. Awnings next to each other let water through at the gaps forming the transitions. Awnings are therefore suitable for protecting smaller areas against the sun and to a certain extent against wind and rain.

4. Solid roof structures, for example made of corrugated iron or other light materials, offer good protection against storms and precipitation, and the problem of water drainage via gutters can also be solved satisfactorily. In the sun, however, such constructions generate heat and prevent ventilation of the area underneath. Most people find such constructions particularly oppressive in the warm season, oppose the feeling of being outdoors and are therefore avoided. Corresponding glass constructions appear optically lighter, but due to the high glass weight require a correspondingly complex statics and drive, which is prone to failure. The glass house effect quickly causes excessive heating due to the expensive construction. Rigid roof structures that are built along a row of houses or above a street are also of concern for safety reasons or cannot be approved, since in the case of emergencies, for example, access to the upper floors of the neighboring houses via an aerial ladder is not possible.

The above-mentioned types of roofing are not able to offer protection from rain as a weather-dependent roofing in pedestrian zones, shopping streets etc. and at the same time enjoy the open air in dry and nice weather. In European pedestrian zones, retailers lose at least 25 to 30% of their turnover each year due to rainfall. In contrast, when the weather is bad, the large shopping arcades and centers record a substantial increase in sales, which means that the grown retail structures in the city centers also lose purchasing power and attractiveness. These are against more popular than shopping centers in dry and nice weather, because in this case, outdoor shopping is preferred by the consumer. Previous roofing concepts have so far failed. ,

It is therefore an object of the present invention to provide an improved and more cost-effective weather-dependent roofing which at least offers protection in the case of rain or excessive sunshine and outdoor enjoyment in dry and beautiful weather.

This object is achieved by a device for roofing with the features of independent claims 1 and 10. Advantageous embodiments of the invention are the subject of the dependent claims.

In a first exemplary embodiment, the roofing device according to the invention comprises one or more awning-like means of transport which are fixedly or releasably connected to one another via the awning surface, as a result of which the system can be used in a particularly flexible manner and the awning surface is held particularly securely by the means of transport which simultaneously serve as cross members. The detachable connection between the individual modules simplifies assembly and maintenance. The substructure is therefore free of cross members and thus easier to design, since rigid cross members or corresponding transverse traction cable and tie rod stiffeners can be dispensed with, which u. a. is necessary in relation to security issues, such as for use with ladder trolleys.

Since, according to one exemplary embodiment, the awning-like transport means can only be moved along one axis on a guide means, the stability of the covering awning surfaces against wind, water and weather increases.

The inclination of the awning surface prevents puddles from forming on the surface and the rainwater drains away quickly. According to an exemplary embodiment, the drainage takes place in the direction of a special rain gutter which is provided in the lower region of an adjacent awning box, as a result of which rain drainage over the awning which is still wound up is prevented even in the event of heavy precipitation. If a gutter box for rainwater is provided along the guide means, the rain drainage is guaranteed, regardless of the position of the awning-like means of transport.

If, according to an exemplary embodiment, the winding of the surface by a spring shaft, as z. B. is known from roller blinds, happens, regardless of the position of the awning-like transport means a tightening of the surface connecting the transport means is guaranteed.

The exemplary embodiment according to independent claim 10 has mutually displaceable struts 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 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 to both sides of the surface, in particular into a gutter box, thereby preventing puddles from forming on the surface and sagging of the surface. The arch shape is advantageous because it improves the statics of the struts, i. H. the struts can be constructed lighter and are still able to carry snow and wind loads.

According to one exemplary embodiment, an inclined support for the unpunished surface which is normally sagging there is provided on the device below the parking position of the struts. 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 exemplary embodiment, the device can be brought into the rest or operating position by means of ropes or chains, as a result of which the labor-intensive, manual movement of the individual struts or awning boxes is eliminated. 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 the 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.

A side roof along the device enables a transition to neighboring houses or sales stands and offers weather protection beyond the area of the awning.

On the one hand, a two-stage drive 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 the following the invention will be explained with reference to drawings, namely that shows

Awning fabric and Fig. 10 is a section through the covered station with the retracted

Awning fabric to explain the folding of the fabric.

The pergola-like construction according to FIG. 1 consists essentially of longitudinal beams 4 and perpendicular to it, serving as a stiffening element, cross beams 2, which are connected to one another like a frame and rest on posts 1 at a height of 4 to 6 m. The frame formed from the support elements 2, 4 covers an area of 6 x 20 to 40 m in the exemplary embodiment. 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. Along the longitudinal beams 4, profiles, for example rails or pipes, are provided on the inside thereof, not shown in detail, which serve as guide means. 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.

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, for example, serve as an interface to neighboring houses or other detached houses Sales stands. In order to maintain the airy character of the pergola construction, the side roof 4 is designed in the form of a glass construction. The side roof also gives the construction a more pleasing, more m wide appearance.

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 character of the awning fabrics creates an open air 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 of 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 to provide the holder 11 in the form of a continuous plate connected to the longitudinal beam 4. In the exemplary embodiment, 11 tube 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 in the wheel arch 30 against wheel shafts 31 directed against each other run the awning box 20 connected to the wheel well 30 via the wheel well fastening 33 and along the running tube 10. It is important that the guide, formed in this embodiment by rollers, in the It is able to absorb both the weight forces of the awning box 20 with the 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 so that they partially lie against 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 each 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 rest

Boxes are moved over the pull exerted on the awning fabric or - each awning box is pulled individually from the rope, which makes a particularly good one

The awning fabric is tightened.

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).

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 e.g. can also be sealed against the ingress of moisture by means of a web or sealing system. The cover 13 explained is particularly useful when the awning fabric is extended during windy bad weather, since it makes it more difficult for the water to flow off to the side at the side of the Mafqi 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 be discharged, for example, through the posts 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. 2. 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 further awning box 20, not shown, to the right of the housing 21 and drains rainwater in its direction.

The further, not shown, awning box is structurally identical to that shown in Fig. 3. As a result, 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 flows into the lower housing space 23, is held in the latter via the end web 27 and finally, as indicated in FIG. 2, is led 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 shaft 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 Marldsen fabric 9, which it occupies in the parking position, determines in particular the S-shaped geometry of the housing 21 of the awning boxes 20, wear and tear significant friction between the awning and the housing edges being avoided when retracting and extending.

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 are recorded by force sensors, the signal can be used for roof control (retracting), for video recording and for alarming security forces.

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 emitters, can be provided in the area of the pergola or awning boxes, which further increases the attractiveness of the system with the adjacent shops in the cool season. As a result, the open-air season can be extended and space can be used more effectively. The mechanics, such as the roll-up mechanism of the spring shaft, the transport rollers and the rain gutters should be heatable (e.g. by heating loops, heat tracing, radiators, warm air or exhaust air from adjacent shops and underground garages) 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 colorful awning fabric, also in connection with color emitters, special mood 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 rest position shown in FIG. 7, the awning fabric would sag about 1.5 meters between the struts, which is why a grid-like inclined support 41 is provided below the parked struts 40, which supports the sagging Fold the awning fabric out of the horizontal when the struts enter the station. The awning fabric is not shown in FIG. 7, which is why reference is also made to FIG. 10.

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, which are guided along the running tube 10 by means of the undercarriage 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 curved 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 opens into a post 1 of the pergola construction.

FIG. 8 also shows the undercarriage with four wheels 32 which are arranged in the same plane to one another and 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.

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, thus exerting a greater force than that designed for longer transport routes Withdrawable. This means there are two drives: a first for the long travel to the end point and a second with a short travel for staggering 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.

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 the 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 structure 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 construction 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. only at one end of posts and held at the other end by a traction rope contraction or carried through one or more central posts like a suspension bridge.

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 arranged one behind the other and at an angle to one another, thereby protecting zones of any design and distances of any length against the weather. Protecting the population from the harmful UV 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 anyway in the urban area (lighting poles, electricity 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 connection 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, since the system's own friction can be better overcome and the tightening is therefore improved.

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