Description

The invention relates to a roof with a membrane, preferably a textile membrane. To protect a surface, for example at events, the membrane can be placed in a roofing position. In this way, free spaces, upwardly open courtyards of buildings or the like can be protected. The membrane protects the spanned surface against hail, rain, sunlight and similar weather-related impairments.

Such roofing must always be sufficiently biased and held against wind and other loads. Many different membrane roof constructions are known in practice, for example in football stadiums. Many membrane roofs, such as the stadium roof in Riyadh, Saudi Arabia, have traction elements in the form of throat ropes and ridge ropes, via which downward and upward forces, for example by wind pressure or wind suction, can be absorbed and dissipated into a supporting structure. Between the throat ropes and the ridge ropes, the membrane is stretched in a zigzag shape.

In many cases, it is also desirable to make the canopy as a convertible canopy and to reciprocate between the canopy layer in which the membrane spans a surface to be protected and a storage layer in which the membrane at least partially clears the surface. Again, there are a variety of constructions. For example, describes DE 100 34 234 C2 a roofing system for roofing large events, in which membrane wings are hinged at the bottom of a cup-shaped central tube. The membrane wings can be brought into contact with the cup-shaped tube and are then in their storage position. They can also be moved into a horizontal roofing position in which they span the underlying surface and in particular protect against precipitation.

From practice also parallel movable, foldable or gatherable membrane roofs are known. The load-bearing ridge ropes of the membrane can be moved along rails in a direction of movement. After the membrane has been moved over the surface to be protected, then the freely suspended Kehlseile be clamped transversely to the direction of movement of the membrane via corresponding clamping devices.

The various known embodiments have the disadvantage that either the opening and closing of the membrane canopy is not provided or brings a great design effort and often a great deal of time with it. As described, in the case of known convertible roofs, the membrane must first be moved out of the storage position into the roofing position and then clamped transversely to the direction of movement.

It can therefore be regarded as an object of the present invention to provide a canopy which provides by simple means a movable between a storage layer and a roofing membrane.

The invention is achieved by a roof with the features of claim 1.

According to the invention, the roofing has a guide device which has two upper guide rails extending in the direction of movement of the membrane and two lower guide rails extending in the direction of movement. In each case one of the two upper guide rails and one of the two lower guide rails is arranged on one side of the membrane. Preferably, all guide rails are parallel to each other.

There are also several the membrane holding transversely to the direction of movement upper tension elements and lower tension elements. The tension members can be formed by cables, straps, chains or similar tensile forces receiving and transverse to its longitudinal direction flexible elements. The upper tension members are connected at both ends with an upper carriage and the lower tension members are connected at both ends with a respective lower slide. The interconnected via a tension element upper or lower slide are mounted on opposite sides of the membrane in an associated guide rail slidably guided in the direction of movement. The upper carriages are each arranged in an upper guide rail and the lower carriages are each arranged in a lower guide rail.

In this arrangement, by the movement of the membrane from the storage position into the roofing position at the same time also a tensioning of the membrane is achieved transversely to the direction of movement. This happens because when moving the membrane in the direction of movement through the membrane itself a tensile force is exerted on the upper tension members and / or lower tension members in the vertical direction, whereby tension the tension elements between the guide rails transversely to the direction of movement. The membrane has no slack areas in the roofing position, in which depressions form and can collect, for example, rainwater.

In one embodiment, the upper tension members and / or the lower tension members are longer than the distance between the two respectively associated upper slide and lower slide, between which they each extend. In the storage position, the tension elements therefore hang through. Due to the membrane shape, the lower tension elements are pulled vertically upwards in the roofing position and the upper tension elements are pulled vertically downwards and then have, for example, an arcuate course. However, no additional electrical, pneumatic, hydraulic or mechanical clamping devices are used for this purpose. Only by the movement of the membrane in the direction of movement of the storage position in the roofing position, the membrane is clamped.

The invention significantly reduces the costs for the roofing of an area, which is often set up only temporarily for an event. In addition, the opening and closing of the canopy can be done very quickly only by the motor moving the membrane in the direction of movement.

The upper guide rails are in particular arranged vertically above the lower guide rails, wherein the horizontal distance between the two upper guide rails and the two lower guide rails can be different in size. Depending on the size of the canopy or the membrane, the distance between the upper guide rail and the lower guide rail measured in the vertical direction may be several meters.

The arranged on a common upper guide rail upper slide are connected to each other via flexible connecting elements, such as connecting ropes, chains, straps or the like. The fasteners transmit only tensile and no compressive forces in their direction of extension. In the roofing position of the distance of the upper slide is thereby given when spreading the membrane. Preferably, a connecting element connects in each case two directly adjacent upper slide, which sit on a common upper guide rail. As it were, a "chain" of the upper carriages on the upper guide rail is produced via the connecting elements. In the storage position, the flexible connecting elements are not tensioned, while they are stretched in the roofing position between two adjacent carriages in the direction of movement.

The upper slide and / or the lower slide preferably have roller bodies, with which they rest on the respective associated guide rail in order to reduce the friction during the movement along the guide rail. For example, the carriages can be designed as so-called recirculating ball slides. Instead of balls and rollers or other rolling elements can be used.

For movement of the membrane between the roofing layer and the storage layer advantageously a drive device is present, which may have an electric, pneumatic or hydraulic drive. In a preferred embodiment, at least one electric motor is provided as a drive motor. Electrical energy is available at almost every site for the canopy. Electrical cables can be easily and quickly connected to the drive motor.

Preferably, the drive motor directly drives one and in particular only one of the upper slides of each upper guide rail. For this purpose, the drive motor can be coupled via a drive element with the relevant upper slide. The other upper slide are moved when moving the membrane of the storage position in roofing position over the membrane or the existing fasteners. As the membrane moves from the canopy to the storage position, the carriage coupled to the drive motor via the drive member pushes the other carriages back into the storage position. Preferably, the drive motor is connected via the drive element to the foremost upper carriage of each upper guide rail, which is the first or foremost upper carriage when the membrane is moved from the storage position to the roofing position.

As a drive element, for example, serve a reefing rope, which couples the drive motor with the respective one upper carriage on the two upper guide rails. The drive of the two upper carriage is therefore similar to the drive of a gondola or a ski lift.

In a preferred embodiment, the arranged on a common lower guide rail lower slide are not directly connected by separate connection means, but only indirectly via the membrane. The position of the lower slide in the canopy position results from the shape of the membrane or adjustment or tension elements present on the membrane, such as tensioning cables or tensioning straps. To adjust the position of the lower slide, the length of the adjusting or clamping elements can be changed, for example via turnbuckles. Each lower slide is seen in the direction of movement between two upper slide arranged, wherein the position of the upper slide is defined in a preferred embodiment of the connecting elements.

It is advantageous if the lower tension elements in the roofing position of the membrane, starting from an apex point to both ends and thus to the two lower slide down towards inclined. About this tendency of the membrane on both sides at each lower tension element can then drainage.

It is advantageous if a gutter is arranged on each lower carriage. The gutter is preferably mounted in a pivot axis extending in the direction of movement pivotally mounted on the associated lower carriage. For attachment of the lower tension member with the lower carriage, a fitting may be attached to the gutter. The gutter can therefore be pivoted during tensioning of the lower tension member in an inclined position, so that along the lower tension member to the relevant membrane side down running rainwater can be absorbed by the gutter and derived in an inlet of a drainage system. This embodiment has the advantage that water dripping from the membrane is avoided and a silent drainage of water is possible. Completely arranged in the direction of movement in the region of the guide rail gutters are not required. It is sufficient to assign each drainage channel in the roofing position of the membrane an inlet. The gutters are moved on the lower slide with the lower tension element and are thus automatically always at the point where the membrane has the lowest level.

In the region of the gutter, the membrane may have a recess, so that the gutter can be pivoted without contact with the membrane. To ensure drainage, an insert, in particular a textile insert can be inserted into the recess between the membrane and the gutter.

The guide rails can be held on holding means on a support member. The support member may be part of a frame or a facade of a building or other stable substructure. A frame made of lattice girders is particularly suitable for the temporary construction of the canopy, for example for events. If the façade of a building is used to attach the guide rails, they can be placed in recesses on the facade to improve the appearance when the membrane is in the storage position.

An upper guide rail and / or a lower guide rail preferably has a plurality of rail sections or rail sections adjoining one another in the direction of movement. These rail sections can be held via holding device in the direction of movement with movement play with respect to the support member. In this way, tolerances in the construction of the support member can be compensated. The rail sections can be seamlessly connected to each other by the game existing in the direction of movement to ensure the unhindered movement of the carriage.

Advantageous embodiments of the roofing according to the invention will become apparent from the dependent claims and the description. The description is limited to essential features of the invention. The drawing is to be used as a supplement.

In 1 is a canopy 15 with a membrane 16 in a canopy situation in which it spans an underlying surface. The membrane 16 is preferably made of textile material and in particular impermeable to water. In this way, places, courtyards of buildings or other places can be protected from the weather, especially from precipitation. The membrane 16 can be between a in 1 represented canopy U and a in 2 storage position A shown in a direction of movement B are moved back and forth. The direction of movement B is oriented in a horizontal plane. In the storage position A is the membrane 16 the canopy 15 the protected in the roofing position U, spanned area at least partially and according to the example almost completely free. In the storage position A is the membrane 16 gathered or folded to form several membrane sections. Adjacent membrane sections extend approximately in the vertical direction V and may abut each other or be arranged side by side at a small distance.

The roofing 15 points to move the membrane 16 between the roofing position U and the storage position A a guide device 17 on. The management device 17 comprises on opposite sides of the membrane seen transversely to the direction of movement B. 16 one upper guide rail each 18 and a lower guide rail arranged lower in the vertical direction V. 19 , In the embodiment shown here is the horizontal distance between the two lower guide rails 19 and the two upper guide rails 18 same size. The vertical distance between an upper guide rail 18 and the guide rail arranged on the same membrane side 19 as well as the distance between the upper guide rails 18 and the lower guide rails 19 in the horizontal direction are the size of the membrane 16 and thus adapted to the size of the area to be protected.

To the guide device 17 also includes several top slides 20 and several lower slides 21 , On each upper guide rail 18 are several upper slides 20 slidably guided in the direction of movement B. The upper sledges 20 are in pairs on the two upper guide rails 18 arranged opposite. The lower sledges 21 are on the lower guide rails 19 arranged. In the embodiment, the number of lower slides 21 on the lower guide rail 19 one less than the number of upper slides 20 , The lower sledges 21 are also in pairs on the two lower guide rails 19 arranged opposite.

In the preferred embodiment, each carriage 20 . 21 a rolling bearing assembly, in particular a ball bearing assembly. Preferably, it is a recirculating ball bearing, with which the respective carriage 20 . 21 on the associated guide rail 18 respectively. 19 supports, so that he with very little force along the relevant guide rail 18 . 19 can be moved. The exact shape of the guide rail 18 . 19 and the sled 20 . 21 can be chosen arbitrarily. In the embodiment, the guide rails 18 . 19 on two opposite longitudinal sides one longitudinal recess each 22 into which a lead 23 engages the associated carriage, as is apparent from the 6 and 9 can be seen.

Two each on the two upper guide rails 18 opposite upper slide 20 are over an upper tension element 27 connected with each other. Similarly, there are two lower slides opposite each other on different sides of the membrane 21 via an under tension element 28 connected with each other. The tension elements 27 . 28 may be formed by tensile forces receiving elements such as straps, ropes, chains or the like. In the embodiment, the tension elements 27 . 28 formed by ropes and preferably wire or steel cables. Due to the different altitudes of the upper slide 20 and the lower slide 21 forms the membrane 16 in their canopy U a zig-zag shape of the lower tension elements 28 to the upper tension elements 27 sloping membrane edges. The upper tension elements 27 are therefore below as ridge ropes 29 and the lower tension members 28 as throat ropes 30 designated.

The on a common upper guide rail 18 arranged upper slide 20 are about flexible fasteners 31 , For example, spacer cables, connected together. The maximum distance between two adjacent upper carriages 20 is by a connecting element arranged therebetween 31 certainly. Two directly adjacent upper slides 20 are via a connecting element located therebetween 31 coupled together, so that similar to a train, a motion-coupled carriage chain is formed. In contrast, the lower slide 21 not connected by additional means. The lower sledges 21 be through the movement of the upper slide 20 over the membrane 16 moved. The position of the lower slides 21 results from the shape of the membrane 16 , Are in the roofing position U, the fasteners 31 cocked and therefore all upper sledges 20 evenly along the upper guide rail 18 spaced apart, are the lower slide 21 in the direction of movement B each seen between two immediately adjacent upper slide 20 ( 1 ).

To move the membrane 16 is a drive device 35 intended. The drive device 35 has at least one drive motor 36 on. In the embodiment described here are two drive motors 36 intended. Each of the two drive motors 36 is a top sled 20 one of the two upper guide rails 18 assigned. Thus drives each drive motor 36 only one upper slide 20 immediately. For this he is about a drive element 37 with this top sled 20 motion-coupled. Beispielsgemäß serves as a drive element 37 a reef rope with which the driven upper slide 20 connected is. The reef rope runs from the drive motor 36 or a driven drive roller along the upper guide rail 18 up to a pulley 38 and from there again parallel to the upper guide rail 18 back to the drive motor 36 or the drive roller.

In a modification to this, it is also possible at both ends of the upper guide rail 18 each to provide a winding shaft on which the drive element 37 or the reef rope is wound up and unwound to the associated upper slide 20 along the guide rail 18 to move. For the design of the drive device 35 There are many possibilities. As a drive motor 36 is preferably an electric motor.

The drive motor 36 is about the drive element 37 with the first or front upper slide 20a connected to the first position on the upper guide rail 18 when moving the membrane 16 is located from the storage position A in the roofing position U. About the fasteners 31 and / or the membrane 16 become the following upper carriages 20 when moving the front upper carriage 20a tightened. Conversely, by moving back the membrane 16 in the storage position A, the front upper carriage 20a the other upper sleds 20 along the upper guide rail 18 push back. It is therefore sufficient, only the front upper slide 20a directly with the drive motor 36 via the drive element 37 connect to.

In one embodiment, the drive element is a reef cable 37 loose through openings in all not directly driven upper slide 20 guided. As a result, sagging of the reef rope can be avoided for long rope lengths.

As explained, each of the upper guide rails 18 one drive motor each 36 with a drive element 37 assigned. Alternatively, only a common drive motor could 36 be present, the two front upper slide 20a on the two upper guide rails 18 drives. In the embodiment described here with two drive motors 36 These are driven coordinated by a control device, not shown. It is also possible the two drive motors 36 mechanically couple together to achieve coordinated motion.

The ropes 29 are longer than the horizontal distance between the two upper guide rails 18 , The throat ropes 30 are longer than the horizontal distance between the two lower guide rails 19 , In the storage position A hang the ropes 29 and the throat ropes 30 therefore down through. When pulling the two front upper slide 20 via the drive device 35 to move the membrane 16 in the canopy U can both the upper slide 20 , as well as the lower sledges 21 initially with little force along the guide rails 18 . 19 be moved in the direction of movement B, as transversely to the guide rails substantially only the weight of the ridge ropes 29 and the throat ropes 30 as well as the membrane 16 acts. Before the membrane 16 reached the canopy U and before all sledges 20 . 21 have reached their final position, the drive device begins 35 exclusively by the pulling movement of the carriages 20 . 21 in the direction of movement B, the membrane 16 to stretch. This happens because the distance between the adjacent upper slides 20 up to the maximum possible through the connecting elements 31 given distance increases and due to the shape of the membrane while the throat ropes 30 at a vertex 45 approximately in the middle between the two lower guide rails 19 is raised. At the same time the ropes 29 through the membrane 16 pulled down. It has been shown that the drive device 35 sufficient, the sledges 20 . 21 to move into the desired position and at the same time the clamping forces transverse to the direction of movement B on the ridge ropes 29 and the throat ropes 30 to create. Additional facilities, the ropes 29 and the throat ropes 30 can span across the direction of movement, can therefore be omitted, what the construction of the canopy 15 considerably simplified and their costs reduced.

To hold the membrane 16 in the roofing position U, the drive device 35 Have locking means, so that the at least one drive motor 36 can be switched off after reaching the roofing position U and does not constantly have to apply a holding force. As an alternative to a locking means can also be a self-locking gear between the drive motor 36 and the drive element 37 be interposed.

The guide rails 18 . 19 are in the preferred embodiment in each case by several in the direction of movement B and thus in the extension direction of the guide rails 18 . 19 running rail sections formed, which abut each other. The guide rails 18 . 19 and thus the respective rail sections are via holding devices 50 on a respective associated support member 51 arranged. As a supporting part 51 For example, a side member of a support structure can serve, for example, an up and degradable transportable and known lattice frame. It is alternatively possible, the guide rails 18 . 19 to attach to the facade of a building.

As in 6 illustrated has the upper guide rail 18 associated holding device 50 a mounting rail 52 on, at the top of the guide rail 18 screwed in several places. Instead of a continuous mounting rail 52 can be used in the direction of movement B shorter fasteners, provided that the guide rail 18 has sufficient inherent stability. The mounting rail 52 has protruding retaining projections in opposite directions 53 on. The retaining projections 53 be from on the supporting part 51 fastened and welded according to example angle elements 54 overlapped. Two angle elements 54 extend in the direction of movement B and are spaced apart so that the mounting rail 52 between the two angle elements 54 can protrude through, but the retaining projections 53 the mounting rail 52 being held. The mounting rail 52 is thus by the two angle elements 54 arranged in the direction of movement B with movement play. Individual rail elements of the upper guide rail 18 can therefore build the roof 15 be moved in the direction of movement B to compensate for tolerances and a gap-free course of the upper guide rail 18 to ensure.

The lower guide rail 19 associated holding device 50 is in 9 shown. On the supporting part 51 is there a extending in the direction of movement support rail 58 attached, which in the embodiment two perpendicular abutting legs 59 having. As already in connection with the upper guide rail 18 associated holding device 50 mentioned, instead of a continuous retaining rail 58 also several holding elements 58 spaced apart along the lower guide rail 19 be provided.

The one leg 59 the retaining rail 58 is with the support part 51 screwed. The other thigh 59 the retaining rail 58 is with the lower guide rail 19 screwed. To tolerances in the construction of the canopy 15 balance, has the retaining rail 58 preferably on the lower guide rail 19 associated leg 59 and / or on the support part 51 associated leg 59 in the direction of movement B extending slot-like slots, so that rail sections of the lower guide rail 19 can be connected flush to each other.

This movement play of the rail sections of the upper guide rail 18 and the lower guide rail 19 in the direction of movement B is advantageous because the tolerances in the construction of the roofing 15 supporting frame usually much larger than the tolerances for the structure of the guide rails 18 . 19 ,

The upper sledges 20 and the lower sledges 19 can be identical. However, the difference to the sled 20 . 21 arranged fittings with which the tension elements 27 . 28 and the membrane 16 at the sled 20 . 21 is attached.

In the 4 to 7 is an embodiment of the upper carriage 20 with a first fitting 60 shown. The first fitting 60 has three plate-like wings 61 on. The three wings 61 give, for example, a Y-like shape of the first fitting 60 , On a substantially vertically arranged wing 61 is about a first pivot 62 a fork-shaped tail 63 the associated ridge cord 69 pivoted. The pivot axis of the first pivot pin 62 extends parallel to the upper guide rail 18 in the direction of movement B. At the other two wings 61 is in each case an attachment point 64 , For example, a mounting hole present at which a belt 65 can be attached. About this belt 65 becomes the first fitting 60 with the respective adjacent lower slide 21 along the edge of the membrane 16 connected.

To connect the respective throat rope 30 with a lower slide 21 carries the lower slide 21 a second fitting 66 , as in the embodiment of the 4 and 8th to 10 evident. The second fitting 66 is about a second pivot 67 on one or more pivot bearing parts 68 around a parallel to the lower guide rail 19 pivotally mounted in the direction of movement B pivot axis. The at least one pivot bearing part 68 is firmly on the bottom sled 21 appropriate. The second fitting 66 has a central fitting plate 69 on, at the throat rope 30 via a bifurcated tail 63 and a first pivot 62 with the second fitting 66 is connected, analogous to the attachment of the ridge cord 29 at the first fitting 60 ,

A major difference between the first fitting 60 and the second fitting 66 is that on the second fitting 66 a gutter 70 is attached. The gutter 70 is therefore on the second pivot 67 swiveling on the lower slide 21 stored. The gutter 70 has a U-shaped shape. The one, inner end 71 the gutter 70 ends above the junction between the throat rope 30 and the second fitting 66 in a recess 72 the membrane 16 , The inner end 71 opposite outer end 73 the gutter 70 is approximately in the area above the lower slide 21 or the lower guide rail 19 ,

How out 4 It can be seen in the recess 72 the membrane 16 an insert 74 , preferably made of textile material or another flexible, foldable material inserted with one end to the membrane 16 above the throat rope 30 Completely watertight completes and its other end within the gutter 70 is arranged. Rainfall water, starting from the vertices 45 on both sides of the membrane 16 along the throat ropes 30 Expires, is thus on the respective use 74 in the assigned gutter 70 directed and does not drip down.

In the roofing position U of the membrane 16 every lower sled takes 21 one by the position of the upper slide 20 and the shape of the membrane 16 predetermined end position P along the lower guide rail 19 one. At each end position P of a lower slide 21 is an immovable enema 80 for receiving the through the gutter 70 flowing rainwater provided. The enema 80 has, for example, an inlet plate 81 on, above the lower guide rail 19 at a distance, so that the lower slide 21 not with the inlet plate 81 collide. In the final position P of the lower slide 21 protrudes the inlet sheet 81 in a space between the lower slide 21 and the outer end 73 the gutter 70 into it. In this way, the precipitation water from the gutter 70 from the inlet sheet 81 taken up and drained into a drainage system. Seen in the direction of movement B are on both sides of the inlet plate 81 side panels 82 provided in common with the inlet plate 81 the enema 80 form.

After the construction of the canopy, the membrane 16 be brought into the roofing position U. In the tension elements 27 . 28 the straps 65 and others to tighten the membrane 16 serving traction means or ropes length adjustment means, such as turnbuckles may be provided. About this Längeneinstellmittel the tension of the membrane 16 and in particular the final position P of the lower slide 21 be defined so that they in the roofing position U of the membrane 16 each one enema 80 are assigned and a proper drainage can occur during precipitation.

In 9 are the pivoting positions of the gutter 70 illustrated. At least in the roofing position U of the membrane 16 is due to the tension of the throat rope 30 the inner end 71 the gutter 70 raised so that the gutter 70 to the outer end 73 is inclined. In this roofing position U of the membrane 16 is the outer end 73 the gutter 70 above the inlet sheet 81 ,

In the storage position A of the membrane is the gutter 70 from the outer end 73 to the inner end 71 inclined to something in 9 is illustrated by dashed lines. This is because the throat rope 30 on the second fitting 66 no pulling force exerts upward, but the gutter 70 or the second fitting 66 due to the weight of the throat rope 30 as well as the membrane 16 is inclined inwards.

At the fittings 60 . 66 If necessary, further openings or retention means can be present. For example, on the membrane 16 or slightly above the membrane 16 be arranged an additional membrane. The additional membrane is preferably formed by a fine-meshed network. It serves to precipitate before it reaches the membrane 16 to atomize to reduce precipitation noise. The additional membrane can be used together with the membrane 16 be stretched between the roofing position U and the storage position A.

The invention relates to a roof 15 with a membrane 16 which can be linearly moved in a direction of movement B between a storage layer A and a canopy layer U. For this purpose, a guide device is used 17 with four parallel to each other in the direction of movement B extending guide rails 18 . 19 , Viewed in the direction of movement B form the guide rails 18 . 19 the corners of a trapezoid and preferably a rectangle. The two front sleds 20a on the two upper guide rails 18 be via a drive device 35 linearly driven. All other sleds 20 . 19 be either over the membrane 16 or via fasteners 31 moved when the diaphragm 16 is moved from the storage position A in the canopy position U. In the reverse movement of the canopy U in the storage position A push the two driven carriage 20a the other upper sleds 20 on the upper guide rails 18 while the lower slide 21 on the two lower guide rails 19 over the membrane 16 to be moved. In this linear Movement are caused by the membrane shape shortly before reaching the roofing position U Kehlseile 30 and ropes 29 between pairs opposite carriages 20 . 21 curious; excited. On additional motorized or manually operated clamping device, the membrane 16 span across the direction of movement B, can be dispensed with.
