    Roller device for awnings, awnings and the like
    The invention relates to a rolling device for awnings, sun sails, internal sun protection devices, surface blinds, horizontal awnings, obscurations and / or similar surface elements comprising a rotatably mounted shaft, on the shaft or about the shaft up and unwindable flexible surface element, a circulating cable system with engages a first portion at a free end of the surface element and is coupled with a second portion and unrolled to the shaft, a drive for rotating the shaft and / or for winding and unrolling of the surface element and the cable system.
    The invention particularly relates to constructions in which at least one flexible surface element is provided on and unwound on a shaft, wherein in the unwound state, the surface element is stretched, so that it has a certain stability.
    The technical field of the invention relates in particular to structures such as awning devices, awning devices and retractable rain roof installations, which include, for example, awnings, awnings and the like.
    Genus-like constructions can be found in the prior art. 2/31 2
    For example, awning devices are known in which a flexible surface element can be wound around an axis. Further, a rope is provided which acts on a free end of the surface element in order to tension the surface element on the one hand and on the other hand to unwind from an axis. It has been found to be advantageous if the cable system is performed circumferentially. This means that the attacking at the free end of the surface element rope is returned via Umienkmittel to the shaft to be wound up there. Advantage of this design is that when extending and retracting the surface element, the free end of the cable system is automatically wound up again, and not separately stowed or wound by hand.
    The prior art awning devices with circumferential cable system have in common that the cable system and / or the surface element is constantly kept under train. This tension is necessary according to the prior art, so that the surface element has a certain basic tension in order to increase the stability. Spring systems act on the cable system. A disadvantage of these constructions is that the spring force acts against the rolling movement of the surface element. In practice, such surface elements are often rolled out by rotating a shaft via a drive. Now acts the spring force against the rolling movement of the surface element, it also acts against the force of the drive. Accordingly, the drive must be dimensioned more powerful, or it must be provided a gear with a larger gear ratio. Especially with manual drives such as winches a larger translation is associated with an uncomfortable operation, as more revolutions are necessary to extend the surface element. A smaller gear ratio would increase the power to roll out the sail, which also makes operation more difficult.
    Another disadvantage of the prestressed, circulating cable systems is that all elements acting on the cable system, such as, for example, elastic tensioning elements, deflection rollers, the drive, etc., are constantly exposed to increased basic stress. As a result, they must be designed for these increased forces. In particular, this means the use of expensive bearings and stronger components. 3/31 3
    Even in the prior art awning constructions, the surface element is biased by spring elements. When winding and unwinding of the surface element must again be worked against this spring force, which again brings the above-mentioned disadvantages.
    The object of the invention is therefore to provide a rolling device for awnings, awnings and the like, which is practicable in use, in particular low driving forces needed and / or fast off and retractable and beyond represents a simplification of the construction. The improved practicability also includes the automatic winding of the cable system.
    The object of the invention is achieved, on the one hand, by providing a tensioning system for tensioning the surface element, and in that the tensioning system can be relaxed for winding and unwinding the surface element, so that the surface element and the cable system are substantially strain-relieved or tension-free for winding and unwinding or On the other hand, that the cable system during winding and unwinding of the surface element has an excess length and is thus substantially relieved of strain and that when winding the surface element, the difference between wound length of the surface element and unrolled length of the cable system is smaller than the excess length of the Seiisystems or that at Unwinding of the surface element, the difference between unwound length of the surface element and rolled-up length of the cable system is smaller than the excess length of the cable system.
    Further features according to the invention are that the tensioning system comprises a blocking device for blocking the cable system or the free end of the surface element, that the cable system is returned to the shaft deflected at least by a deflection means, wherein the deflection means is preferably designed as a deflection roller and / or that the blocking device Cable clamp, a rope clamp on a pulley, a lockable pulley, a detachable mechanical connection, a reeling of the cable system on the shaft, which acts against the tension, a mechanical connection of the cable system to the 4/31 4
    Shaft or a releasable mechanical connection of the free end of the surface element comprises
    Advantageously, the device is designed such that both the surface element and the cable system by rotation of the shaft on this up and unwound and / or up and unrolled and that the surface element by rotation of the shaft and winding the Flächeneiements with blocked cable system or blocked free end of the surface element is tensioned, that the surface element, in particular in unwound position, by rotation of the shaft in an arbitrary direction of rotation can be wound and tensioned and / or that the clamping system comprises a releasable locking device for fixing a third cable section of the cable system and / or that the blocking device and the third cable section are arranged in the course of the cable system between the first Seiiabschnitt and the second cable section.
    Further advantageous feature combinations are that the clamping system is provided a rotation blocking device for blocking a rotation of the shaft against the torque caused by the tension of the Flächeneiements or against the tension exerted by the cable system, that the rotation blocking device preferably as a self-locking gear, as a self-locking drive, as a self-locking worm gear in the form of a ratchet or a releasable mechanical connection, the surface element is wound around a first winding circumference, the cable system is wound around a second winding circumference, preferably the first winding circumference is greater than or equal to the second winding circumference and / or during unwinding of the surface element, the unwound length of the surface element is greater than or equal to the rolled-up length of the cable system and / or that in the course of the cable system, an elastic tensioning element is arranged, which is spanned at Flächenele ment acts with a clamping force against the tension of the surface element and / or the cable system and that acting against the tension of the surface element and / or the cable system clamping force of Spanneinements when rolling up and unrolling the surface element is substantially zero, that of the cable system on the Clamping element exerted resulting force in the tensioned state is smaller than the biasing force of the clamping element that two surface elements are connected up and unwound connected to the shaft, that the two 5/31
    Surface elements on both sides of the shaft by actuation of the drive can be extended and tensioned and / or that the cable system comprises a plurality of ropes are individually up and down roll bar coupled to the shaft or that the ropes are connected together in the course of the cable system and as a single rope can be rolled up and unrolled with the shaft.
    Furthermore, it can be provided that, for tensioning the surface element, the wound-up length of the surface element is greater than or equal to the excess length of that section of the cable system which lies between the blocking device and the free end of the surface element.
    The device according to the invention comprises a flexible surface element, which has a certain tension in the clamped state in order to increase the stability. Tension-free surface elements that are substantially strain-relieved or de-energized would sag freely. The stability, for example, against wind forces, would not be given on the one hand endangers the safety and on the other hand brings unpleasant side effects such as noise and changing position of the surface element with it.
    In order to tension the surface element, a clamping system is provided according to the invention. However, this clamping system is designed to achieve the object according to the invention such that, in spite of the tension of the rolled surface element, the handling of the device is not impaired. In particular, the tensioning system for winding and unwinding of the flexible surface element is deactivated, deactivated, relaxed, relaxed or relieved. This means that the surface element is stretched and / or tensioned in the extended state via the clamping system. For and / or during winding and unwinding of the surface element, however, the tension is reduced or reduced in such a way that the surface element and / or the cable system is substantially relieved of tension or de-energized
    In this case, a stress state in which the tensioning system is deactivated and / or relaxed is defined as essentially tensionless. With a relaxed tensioning system, the cable system and / or the surface element is exposed to little or no tensile stress. For example, even with a freely sagging 6/31 6
    Surface element given a certain basic tension by gravity. Furthermore, a certain basic tension is given by elastic design of the rope of the cable system. However, this basic voltage and / or a tension of the tensionless state is many times lower than the tension with a tensioned surface element.
    According to the preferred embodiment of the invention, the cable system has an excess length and is thereby relaxed. This is the sei! the cable system by the extra length longer than the shortest possible route of the cable system between the reeling on the shaft and the connection point with the surface element. Only upon activation of the clamping system and / or the blocking device and rotation of the shaft by the drive, this excess length is at least partially compensated or tensioned.
    According to the embodiment of the deactivatable clamping system brings several advantages. On the one hand, this facilitates the rolling up and unrolling of the surface element on the shaft, since no tension force acts against the drive torque. As a result, a weaker drive and / or a smaller ratio of the drive can be selected. In particular, in the embodiment of the drive as a hand crank a considerably faster rolling up and unrolling of the surface element is thereby made possible with the same force However, even with the provision of an electric drive such as an electric motor or the like a faster winding and unrolling of the surface element allows.
    In addition, cost-effective, simple components can be used by the lower mechanical stress. This concerns in particular the drive but e.g. also deflection such as pulleys etc.
    In the course of the cable system, according to one embodiment, nevertheless an elastic tensioning element can be provided. In particular for cushioning dynamic force changes such as by a gust of wind or by dynamic mechanical stresses, it is advantageous if an elastic clamping element is provided, which limits the mechanical load of the cable system and the surface element within certain limits. For this purpose, an elastic clamping element according to the invention can be provided, soft against the clamping force of the 7/31. 7
    Rope system and / or the surface element acts. If the tension of the system now increases, for example as a result of a gust of wind, the elastic tensioning element will yield. This reduces the voltage or at least the gradient of the voltage increase and the voltage spike, which would otherwise act unrestrained on the system, is attenuated and / or cushioned. The clamping element is designed for example as a gas spring, gas spring, steel spring, flexible support or as a rubber buffer.
    The tensioning system according to the invention comprises means which are adapted, on the one hand, to increase the tension in the clamped state and, on the other hand, to be able to relieve the cable system and / or the surface element.
    The cable system basically comprises several sections. With a first section, the cable system engages a free end of the surface element. Furthermore, the cable system is preferably deflected by deflecting means such as pulleys and the like and guided back to the shaft. The shaft about which the surface element can be wound up, according to the preferred embodiment, is set up or suitable for winding up a second cable section of the cable system as well. For this purpose, a cable drum can be provided on the shaft. On this cable drum, the cable system can be rolled up and down. Preferably, this cable drum can be rotationally rigidly connected to the shaft.
    As a circulating cable system, in particular, a cable system is defined, which engages with a first cable section at a free end of the surface element and is coupled with a second cable section up and unwound with the time. Furthermore, the cable system is preferably returned to the shaft by a deflection means such as a pulley. Further, the circulating cable system is designed such that the surface element is wound around a first winding circumference, that the cable system is wound around a second winding circumference.
    The device may be designed such that the first winding circumference is greater than or equal to the second winding circumference. As a result, during unwinding of the surface element, the unwound length of the surface element is larger or essentially the same size as the roughened length of the cable system and when winding up the surface element the wound length of the surface element is greater or essentially the same size as the unrolled length of the cable system.
    However, it also corresponds in the spirit of the invention that when rolling out of the surface element substantially the same length of the cable system is wound up. Since the surface element is preferably wound in several layers one above the other, the winding circumference of the surface element changes with increasing winding. The smallest winding circumference preferably corresponds to the circumference of the shaft. According to one embodiment, however, the cable system is preferably not wound up in a multi-layered manner, but rolled up adjacent to one another in a helical manner. Thus, the winding circumference of the cable system is substantially constant, while the winding circumference of the surface element depends on the wound-up length of the surface element. The winding circumference of the cable preferably corresponds to the circumference of the cable drum or the circumference of the shaft.
    Preferably, the ratio is selected such that the unwinding of the surface element, the cable system does not or only slightly spans or that relax the Seiisystem and the surface element during unwinding.
    Preferably, the device is designed such that the difference between wound length of the surface element and unwound length of the cable system is less than the excess length of the cable system or during unwinding of the surface element, the difference between unwound length of the surface element and rolled up length of the cable system is smaller than the excess length of the cable system.
    For tensioning or when the tensioning system is activated, the rolling device is designed such that the wound-up length of the surface element is greater than or equal to the excess length of that section of the cable system that lies between the blocking device and the free end of the surface element.
    The clamping system is adapted to be able to cause on the one hand a tension of the rolled surface element, but on the other hand to allow a substantially tensionless winding and unwinding of the surface element. 9/31 g
    For this purpose, according to one embodiment, a blocking device is provided for fixing a third cable section. This blocking device is provided in the course of the cable system, in particular between the first and the second cable section.
    The blocking device according to the invention can be used, for example, as a fixing device, e.g. Rope clamp, be designed as a mechanical, releasable connection means for the rope or other impact-like structures. The effect of the blocking device is that the corresponding portion of the cable system or the surface element is stationary or at least relatively fixed in place or that the force acting on the cable system clamping force of the surface element is counteracted. Fixed in place is in particular a blocking or fixation relative to the environment or one of the fastening points.
    Furthermore, the tensioning system preferably comprises a rotation blocking device for blocking the shaft. To tension the surface element, a clamping force must act on the surface element. Since the surface element is wound on the shaft, this torque creates a torque about the axis of rotation of the shaft. In order to prevent an automatic relaxation, a rotation blocking device is provided for blocking a rotation of the shaft against the torque caused by the voltage or against the tension exerted by the cable system. This can for example be designed as a self-locking gear, as a self-locking drive, as a self-locking drive, as a mechanical connection means, as a ratchet or the like.
    The rolling device according to the invention can be configured in different embodiments. For example, two substantially diametrically oppositely oriented surface elements can be wound up and unwound from the shaft. This would correspond to a common construction of a solar sail. Furthermore, essentially square floor elements can be unilaterally unwound in order to essentially correspond to the function of an awning. These have according to one embodiment, two free ends, each at a free end of a 10/31
    Rope portion of the circulating cable system is provided. Furthermore, a plurality of cable systems may be provided to return a plurality of free ends of the surface elements to the shaft.
    Furthermore, the cable system may comprise deflection rollers, which are in turn connected to cables for their part.
    In a further consequence, the invention will be further described with reference to the figures.

    Fig. 1 shows a schematic oblique view of a rolling device according to the invention with a shaft 1, which is rotatably supported on both sides provided at fastening points 14. In the present embodiment, the attachment points 14 are designed as pillars, which are for example firmly anchored in the ground. On the shaft two surface elements 2 are provided. These are connected and unwound connected to the shaft 1. They have a substantially triangular shape, wherein at the respective free ends 5 of the two surface elements 2, the cable system 3 attacks. The cable system 3 comprises a first cable section 4, which is connected to the free end 5 of the surface element and / or acts on this. Furthermore, the cable system 3 comprises a second cable section 6, which is coupled up and unwound with the shaft 1. Further, a drive 7 is provided over which the time can be turned ger. This rotation causes on the one hand a winding and unwinding 11/31 11th
    Surface elements and the winding and unwinding of the cable system, in particular the second cable section. 6
    In the present embodiment, the cable sections adjoining the two first cable sections 4 are brought together at a connection point 15 and are preferably connected via a deflection means 12 to a single cable, at whose connection point 15 opposite end the second cable section 6 is provided. Along the cable system a plurality of deflection means 12 are provided according to the present embodiment. Examples of such deflection means are rollers, rollers, deflection bolts or the like. Preferably, rollers and in particular rotatably mounted rollers are used. About the deflection of the cable system is guided so that the second cable section 6 on the shaft and can be rolled up. Furthermore, a tensioning element 13 is provided in the course of the cable system in the present embodiment. This acts against the clamping force of the cable system and / or subsequently against the clamping force of the surface elements 2. The clamping element 13 is preferably designed as an elastic clamping element and comprises an elastic body which opposes a change in length of a certain spring force.
    The cable system is guided in the region of the free ends 5 and / or in the region of the first cable sections 4 about deflecting means 12, which are provided at further fastening points 14. These attachment points can be designed, for example, as anchored in the ground uprights or supports. Furthermore, in all mounting locations 14 of all embodiments, however, a design as a wall anchor, column, hook or the like is possible.
    According to the invention, the rolling device comprises a tensioning system 8. The tensioning system 8 comprises one or more components which are suitable for tensioning the surface element or maintaining and / or generating a tensioning force. In addition, the clamping system according to the invention is suitable for enabling a substantially tensionless winding and unwinding of the surface element or of the surface elements. 12/31 12
    In the present embodiment, the clamping system 8 comprises a blocking device 9. The blocking device 9 is suitable and / or adapted to fix a third cable section 10 of the cable system 3. In particular, the third cable section 10 is fixed in place by the blocking device 9. This fixation takes place, for example, at the fastening point 14 or at a rigidly connected to the attachment point 14 position. Furthermore, the clamping system 8 comprises a rotation blocking device 11, which is suitable and / or adapted to block a rotation of the shaft due to the tension of the cable system and / or the surface elements. Possible embodiments for the blocking devices are cable clamps, mechanical cable clamps, releasable mechanical connection means and other constructions which are suitable for temporarily fixing the third cable section in a substantially stationary manner.
    The rotational locking device 11 of all embodiments is designed for example as a self-locking gear, self-locking drive, self-locking gear drive, ratchet, mechanical rotation blocking device or other device that is adapted to prevent rotation of the shaft against the surface element acting forces.
    The drive itself can be designed according to all Ausführungsbeispieie the invention, for example, as an electric rotary drive, as an electric drive, as a wheel drive, as a crank drive, as a mechanical hand crank with worm gear or similar constructions. Preferably, the drive on a worm gear, which is self-locking.
    2 shows a substantially corresponding to FIG. 1 embodiment of the rolling device according to the invention in a schematic representation. Again, two surface elements 2 are provided wound on a shaft 1. At the free ends 5 of the surface elements 2 each engage a first cable section 4 of the cable system 3. About deflection 12, the cable system is guided to the shaft 1. The shaft is rotatably mounted on fastening parts 14 and driven via a drive 7 rotatable 13/31 13 driven and / or driven. Furthermore, in the course of the cable system 3, a blocking device 9 and a clamping element 13 are provided.
    In the present embodiment, the cable system 3 is executed circumferentially. This means that when the surface elements are unwound and wound up, the ends that become free as a result are rolled up again. For this purpose, the rope sections acting on the surface elements 2 are brought together at a connection point 15 and connected to a further, second cable section 6, which can be wound around the shaft 1. The merging of the two cable sections is done in the present embodiment by a further deflection 12. However, the two cable sections can also be connected to each other via fixed connection means. Now, if the surface element is rolled from the illustrated rolled-out position, the shaft 1 is rotated via the drive 7, so that the surface elements wind up on the shaft 1. In this case, the connection point 15 shifts in the illustrated embodiment from right to left. The required change in length of the second cable section 6 is done by rolling from the shaft. 1
    3a shows a further embodiment of a rolling device according to the invention in a schematic representation. Analogous to Figures 1 and 2 surface elements 2 are up and unwound on a shaft 1 is provided which is rotatably mounted in a preferred manner and rotatably driven. For this purpose, a drive 7 and attachment points 14 are provided.
    Further, the device comprises a circulating cable system 3, which attack according to the foregoing description with first cable sections 4 at the free ends 5 of the surface elements 2 and are guided over deflection means 12 to the shaft. According to the embodiment of FIG. 3 a, the cable system 3 comprises two second cable sections 6 which are aufrolibar by rotation of the shaft on the same. In contrast to the embodiment according to FIG. 1 and FIG. 2, the merging of the two cable sections at a connection point 15 is omitted. In this embodiment, the tensioning system 8 according to the invention comprises two blocking devices 9 for fixing one of the two third cable sections 10. According to an alternative embodiment the two blocking devices 9 may also be brought together or be coupled in such a way that both third cable sections 10 are fixed by the actuation of a device,
    FIG. 3a shows a rolling device according to the invention in an extended position, that is to say with unwound surface element and / or unwound surface elements. Fig. 3b shows the same device as Fig. 3a, but with retracted surface elements or wound surface elements.
    If now the surface element is moved from a position wound up as in FIG. 3b into an extended, unwound position as in FIG. 3a, the following steps are carried out:
    The drive 7 rotates the shaft 1, so that the surface elements 2 are unwound. At the same time, the second cable sections 6 are wound on and / or around the shaft 1. The cable system 3, which is guided around deflecting means 12 from the shaft to the free ends 5 of the surface elements 2, engages with the first cable sections 4 at the free ends 5 of the surface elements 2. By rolling up the cable system 3 around the shaft, the cable system attracts with its first cable sections 4 at the free ends 5 of the surface elements 2. In this case, the cable system 3 and the surface elements 2 are essentially stress-relieved or strain-relieved in a preferred manner. The rolled-up length of the cable system 3 in this movement substantially corresponds to the unwound length of the surface elements 2 in selbiger movement. As a result, the sum of these two lengths is substantially constant, whereby the voltage state is also substantially constant during winding and unwinding. If the rolling device according to FIG. 3 a is extended and / or the surface element unwound in a desired position, then the entire cable system and the surface element 2 are in an essentially strain-relieved, dead state. In order to tension the surface elements 2, the clamping system 8 becomes more active! According to the embodiment of FIGS. 3 a, 3 b, 1 and 2, the blocking device 9 is activated or the blocking devices 9 are activated for this purpose, whereby the cable system 3, in particular the third cable sections 10, are fixed in a stationary manner. Subsequently, the drive 7 is rotated in a direction which causes a winding of the surface elements. However, since the third cable sections are fixed by the blocking devices, the surface element and one or more parts of the cable system 3 are tensioned. If the desired tension of the surface elements is reached, the drive can be stopped. As a result, the rotation blocking device 11 is activated. This prevents an automatic reverse rotation of the shaft under the influence of the tension of the surface elements or the cable system. Preferably, this rotation blocking device 11 is designed as a self-locking gear. This has the advantage that no additional operable mechanical rotation blocking device must be provided. Rather, the rotation blocking device 11 is inherently realized by the transmission. Advantageously, therefore, the drive must only be rotated until the surface elements are stretched. If the drive stops, the system and / or the surface elements 2 remain taut.
    In this tensioned state, the tension of the surface elements 2 may also act against the clamping elements 13. These are preferably provided in all embodiments between deflecting means 12 and fastening points 14. When the tensioning system 8 has been activated and / or the state of tension is substantially tension-relieved, the tensioning elements 13 are arranged essentially without effect or without tension in the course of the cable section.
    4 shows a further embodiment of a roil device according to the invention. Again, a shaft 1 is rotatably mounted on fastening parts 14 are provided. A drive 7 is set up and / or suitable for winding or unwinding a surface element 2 via a rotation of the shaft 1 and for winding or unrolling a cable system 3.
    In the present embodiment, the surface element 2 comprises two free ends 5. At these two free ends 5 each first cable sections 4 of the cable system 8 attack. Furthermore, the cable system is returned via deflection 12 to the shaft 1. The mode of operation essentially corresponds to the rolling devices of FIGS. 1 to 3. As a distinguishing feature in the present embodiment, the cable system 3 is designed such that two second cable sections 6 can be wound or wound on two different positions on or around the shaft. According to an alternative embodiment, however, the two second cable sections 6 can be brought together and wound up at only one point on or around the shaft. Furthermore, the embodiment of FIG. 4 also includes a 16/31 16
    Clamping system 8, the blocking devices 9 for fixing third cable sections 10 has. Also provided is a rotation blocking device 11, which are designed to be substantially equivalent to the Drehbiockiervorrichtung the previous embodiments. So come z, B. Self-locking gearboxes, self-locking drives or mechanical blocking agents are used. The embodiment of Figure 4 is of their mode of action and of the operation of the clamping system 8 is the same effect as the previous embodiments
    Fig. 5 shows a possible clamping element 13 in a schematic sectional view, as it can be used for example in the preceding embodiments. The tensioning element 13 comprises a first engagement point 16 and a second engagement part 17. For example, the first engagement point 16 is connected to a fixed attachment point 14 and the second engagement point 17 is connected to a deflection means 12. The main body 18 is rigidly connected to the first engagement point 16 which a punch 20 is linearly guided and / or stored. The stamp has at its second attack point 17 opposite region on a plate 21. Further, the main body 18 is provided with a shutter 19 through which the punch 20 is passed. Between the plates 21 and the shutter 19, a compression spring 22 is provided. This compression spring has a certain spring constant and / or a certain spring characteristic. Preferably, the compression spring 22 is provided biased between the plate 21 and the shutter 19 in the main body 18. Thus, a force for displacement of the second point of attack 17 relative to the first point of attack 16 is necessary, which is greater than the spring force of the compression spring 22 in this biased state. If the spring force is exceeded, for example, by a mechanical force acting on the surface element, then the second point of application 17 is displaced relative to the first point of application 16. By further tension of the compression spring, the force increases. However, the tension peak is cushioned by the movement and displacement of the two points of engagement with each other. Preferably, the biasing force of the spring or the tensioning element is selected to be greater than the force transmitted by the statically tensioned surface elements from the cable system to the tensioning element 13 is exercised. Thus, with strained surface element 2 no displacement of the first point of attack 16 against the second point of attack 17 is given. Only by a 17/31 17 dynamic load, such as by a gust of wind, there is a change in length of the clamping element 13. This has the advantage that the deflection 12 always come to lie in the same places in normal, but also in tensioned state ,
    Designated as a compression spring elastic element of the clamping element 13 may be replaced or supplemented according to the invention and in all embodiments by similar elastic means. Examples are tension springs which are loaded with tension or rubber buffers as well as similar and equivalent elastic elements.
    The Biockiervorrichtung 9 may be carried out according to the invention as a device which is adapted and / or adapted to fix a rope section stationary at least temporarily, in addition to the above devices also devices may be used in all embodiments, the example of sailboats as Schotklemmen are known. These devices have clamping bodies through which the cable and / or the cable system is led hindurehgeführt. The cable can be moved freely in one direction. If the rope is moved in the opposite direction, the device automatically locks and the corresponding cable section is fixed. Advantage of such a construction in combination with the present invention is that the Abwickein the surface elements and simultaneously rolling up the cable, the rope can be passed unhindered through the sheet clamp. For clamping the surface element, the direction of rotation of the drive is reversed according to the above description. As a result, the direction of movement of the cable or the third cable section is reversed. In this case, locks the blocking device designed as a sheet clamp and the surface element can be tensioned. This results in the advantage that purely by actuation of the drive, which is designed for example as a hand crank, the surface element can be handled and by simple reversal of the direction of rotation of the drive, the surface element can be stretched. A Schotkiemme can be subsumed under the above term "rope clamp". For winding the surface element, the fixation of the third cable section can be solved. This is done, for example, by removing the cable section from the sheet clamp. For all embodiments according to the invention, the blocking device can be arranged in the region of those fastening parts in which the drive 7 is arranged. As a result, the operation is easier. For example, the surface element can be rolled out and stretched by a person. For example, the blocking device 9 may be provided on the post of the device. Actuators for the drive may also be provided in this area. Examples include a hand crank with mechanical drive or switch to activate an electric drive.
    Furthermore, in this context, a cable or cable is understood to be an element or a combination of several elements which are suitable for carrying out the functions according to the invention. In particular, the term rope also includes belts, straps, straps, steel cables, plastic cables, rod-shaped elements, chain-like elements and the like.
    According to another embodiment of the invention, the blocking device is designed as a fixable deflection roller, as a cable clamp on a deflection roller or as a lockable deflection roller. In this case, for example, a lever is provided which clamps the cable between the guide roller and a cam located on the lever. This fixes the rope in this area. Particularly preferably, the blocking device is arranged at that deflection roller which is arranged along the cable system 3 closest to the free end 5 of the surface element 2. By fixing the cable system 3 in the region of the fastening points 14 of the deflection rollers 12, the force acting on the fastening points 14 can be reduced. If, according to one of the preceding embodiments, the rope is blocked in the region just before the rope is wound on the shaft 1, the cable system acts on the said deflection means 12 or the fastening points 14 like a pulley, whereby the forces acting on these elements during tensioning act, are increased. If, on the other hand, the blocking device 9 is arranged in front of the deflection of the seeding system 3 or during the deflection of the cable system 3, this additional loading for the said elements is eliminated. This embodiment is thus characterized in that the blocking device 9 of the preceding embodiments is provided in that deflection roller, which in the course of 19/31 19
    Seiisystems is arranged immediately in front of the free end of the surface element 2, or of which the cable system is preferably deflected directly to the free end 5 of the surface element 2. Preferably, this blocking device 9 is designed as a cable clamp on the deflection means 12 for fixing the rope.
    According to a further embodiment of the invention, no separate blocking device 9 is provided. When unwinding the surface element 2 from the shaft 1 and simultaneously winding the squeegee system on the shaft 1, the surface element 2 is unwound from the shaft 1 until it is completely unwound. If now the shaft 1 is further rotated in the same direction via the drive 7, then the surface element 2 winds again on the shaft in the opposite direction of winding. In contrast to this winding direction, however, the cable system 3 and in particular the second cable section 6 is further wound on the shaft. This results in a tension of the surface element 2 and the cable system 3. In this embodiment, the tensioning system 8 thus comprises the circumferential cable system 3 according to the preceding embodiments and a drive and a surface element 2, which is suitable and / or set up to be wound on the shaft in the opposite winding direction and thereby act against the rolling movement of the cable system, the blocking device 9 is as acting against the clamping force reeling of the cable system on the shaft or as a mechanical connection of the cable system with the wave executed.
    According to a further embodiment, the rolling device for sun sails is designed such that in the course of the cable system 3, an elastic tensioning element 13 is arranged, which acts in tensioned surface element 2 with a clamping force against the tension of the surface element 2 and / or the cable system 3 and that against the Voltage of the surface element 2 and / or the cable system 3 acting clamping force of the clamping element 13 during winding and unrolling of the surface element 2 is substantially zero. 20/31 20
