The support rod (3) has a lower contact surface (22) for the floor (4), an upper contact surface (25) for the ceiling (5), and an elastic element (10) that generates a clamping force whereby the rod (3) is fixed between the floor (4) and the ceiling (5) once installed.

Description

[0001] The present invention relates to an awning system comprising an awning, in particular a folding arm awning, according to the preamble of claim 1. The awning system is particularly suitable for installation on balconies.

[0002] Awnings, such as folding-arm awnings, are typically mounted at their installation location, especially on a balcony, using wall or ceiling brackets. These brackets can be subjected to high pull-out forces resulting from the awning's own weight and environmental factors, particularly wind when the awning is extended. This necessitates a complex installation process. For example, anchoring with numerous heavy-duty anchors, especially M12 heavy-duty anchors, is required for each bracket. This is particularly relevant for folding-arm awnings, where the brackets must withstand exceptionally high pull-out forces. This makes installation, removal, and / or modification of the awning more difficult.

[0003] The generic patent DE 20 2013 005 682 U1 discloses a clamping awning system for clamping an awning between two mounting surfaces, the support devices of which are secured against unintentional tipping over. A support device comprises a support foot and a tensioning device, which are arranged laterally offset from each other. The support foot has a clamping device at each of its ends, at least one of which is height-adjustable. The tensioning device is spring-loaded and rests against the ceiling and against a bracket that is fixed to the support foot. It has a compression spring that sits on a tensioning bolt. A spring tensioning element is screwed onto the tensioning bolt. The spring force is individually adjustable. The installation of this clamping awning system, or rather the adjustment of the tensioning device, is often difficult.

[0004] DE 70 46 018 U discloses an awning fixed by means of support columns, wherein the clamping force is adjusted by means of adjusting plates and nuts.

[0005] From DE 78 02 048 U1, a clamping support, for example for the construction industry, is known which has an inner tube that is telescopically mounted in an outer tube. One end of a helical compression spring is fixed to the inner tube. The other end of the spring is supported by a sliding tube guided in the outer tube. To adjust the length and clamping force, the sliding head can be guided along a longitudinal slot in the outer tube via a transverse bolt and locked in transverse slots of the same.

[0006] It is therefore the object of the present invention to provide an awning system that enables flexible and reliable installation of the awning, in particular a folding arm awning, for example on balconies.

[0007] This problem is solved by an awning system with the features specified in claim 1. The awning system comprises an awning and at least one clamping rod for clamping the awning to a location between a floor and a ceiling. The at least one clamping rod has a lower contact surface for contact with the floor, an upper contact surface for contact with the ceiling, and a spring element for generating a clamping force that holds the clamping rod securely between the floor and the ceiling when installed. The awning is held simply and reliably clamped between the floor and the ceiling by means of the clamping rod. Applying the clamping force via the spring element has the advantage that a complex anchoring system in a wall or ceiling, capable of withstanding the awning's pull-out forces, is not required. This allows for easy and flexible installation and removal of the awning.This makes the awning particularly suitable for installation on balconies.

[0008] The clamping force required to hold the awning system is generated, at least in part, by the spring element. The spring tension of this element presses the upper and lower contact surfaces against the ceiling and floor, respectively. At least one clamping rod is wedged between the floor and ceiling. The spring element advantageously allows for flexible and easy adjustment of the clamping force. The clamping force can be selected based on the extension force to be withstood, for example, depending on the desired wind resistance class of the awning. The wind resistance class can be determined, for example, according to DIN EN 13561. The upper limit of the clamping force can be set, in particular, based on the maximum permissible point load on the floor and / or ceiling at the installation location.

[0009] Another advantage is that the spring element allows for length compensation. The clamping force generated by the spring element can be maintained even with changes in length, for example, due to variations in the distance between the floor and ceiling. Unlike clamping rods without a spring element, the clamping force is not dependent on a precisely defined distance between the floor and ceiling. This is particularly important for installation on cantilevered balconies. These can oscillate, which can lead to significant changes in the distance between the floor and ceiling.

[0010] The at least one clamping rod comprises a housing tube and a telescopic tube axially displaceable within it, the telescopic tube being arranged at a free end of the spring element. The spring element is compressed within the housing tube depending on the insertion path of the telescopic tube. This allows for simple and precise adjustment of the clamping force and compensation for length variations.

[0011] The spring element is preferably mounted completely inside the housing tube. This protects the spring element from environmental influences and contamination.

[0012] The housing tube can, for example, be an aluminum tube, in particular an aluminum round tube.

[0013] A fixed end of the spring element, opposite the free end, is axially fixed relative to the housing tube. This ensures that the compression stroke of the spring element, and thus the resulting clamping force, can be easily determined by the insertion stroke of the telescopic tube. Variations in the clamping force due to displacement of the fixed end of the spring element relative to the housing tube are avoided. The fixed end of the spring element can be attached directly or indirectly to the housing tube.

[0014] The fixed end of the spring element can be attached in different axial positions within the housing tube to adjust the basic length of the clamping rod. The clamping rod can be easily adapted to different installation locations, particularly to varying distances between the floor and ceiling.

[0015] Preferably, the fixed end of the spring element is indirectly attached to the housing tube via a length adjustment device. The axial position of the fixed end of the spring element can be flexibly set using this length adjustment device. Multiple axially arranged adjustment mounting points, especially adjustment bores, have proven particularly suitable, as each can be engaged. For example, the adjustment mounting points, especially adjustment bores, can be located in an adjustment tube at the fixed end of the spring element and / or in the housing tube. An adjustment tube with multiple axially arranged adjustment bores has proven particularly suitable. For example, the desired adjustment bore of an adjustment tube can be aligned with a through-hole in the housing tube and fixed in the respective axial position by a fastening element.This allows for a structurally simple and stable variation of the basic length of the clamping rod.

[0016] It is also possible to provide several through-holes in the housing tube to make the length adjustment even more flexible.

[0017] The at least one clamping rod has a length adjustment unit for adjusting the clamping travel by which the spring element is compressed for a given overall length of the clamping rod. This allows for flexible adjustment of the clamping force independent of the overall length of the clamping rod. The overall length of the clamping rod corresponds, in particular, to the distance between the floor and the ceiling. The length adjustment unit makes it possible to adjust the clamping force independently of this distance. This advantageously simplifies installation, as the clamping rod does not need to be compressed against the ultimately required clamping force during installation. Specifically, the clamping rod can first be placed without tension between the floor and ceiling in order to subsequently adjust the clamping force.

[0018] The length adjustment unit can be designed, in particular, to adjust the axial position of the housing tube relative to the telescopic tube at a given overall length, especially at a given distance between the top and bottom. This allows, in particular, the immersion path of the telescopic tube to be varied in order to compress the spring element, especially a helical compression spring of the spring element.

[0019] The length adjustment unit is designed as a height-adjustable foot, specifically for adjusting the axial insertion path of the telescopic tube into the housing tube. This allows for particularly easy access and adjustment of the clamping path. For example, the height-adjustable foot can be located at the end of the telescopic tube furthest from the spring element. By adjusting the length of the foot, particularly its height relative to the end of the telescopic tube, the telescopic tube is axially displaced within the housing tube at a predetermined overall length. For example, the height-adjustable foot can be screwed in or out relative to the telescopic tube.

[0020] A particular advantage of the height-adjustable foot is that the adjustable clamping range correlates directly with the height adjustment. The clamping range can be set easily and precisely. For example, based on the spring characteristics of the spring element, a desired clamping force can be assigned to the respective clamping range or height adjustment.

[0021] The awning is preferably a folding-arm awning, for example, in the form of a cassette awning. Folding-arm awnings, especially compared to window awnings, exhibit particularly high extension forces, which complicates their installation. In particular, installation using clamping rods for folding-arm awnings is only possible thanks to the spring element, as this reliably ensures sufficient clamping forces, especially while simultaneously allowing for length compensation.

[0022] According to a preferred aspect of the awning system, the clamping force is applied exclusively via the spring element. This allows for particularly simple and precise adjustment of the clamping force, independent of other clamping elements, especially rigid ones. This simplifies length compensation, particularly when the distance between the floor and ceiling varies.

[0023] According to a preferred aspect of the awning system, the spring element comprises at least one compression spring, in particular at least one helical compression spring. The spring element may have one or more spring components. Disc springs, helical springs, and / or gas springs are particularly suitable. The spring element preferably comprises at least one helical compression spring. Compression springs, in particular helical compression springs, have proven to be particularly suitable for generating the required clamping force. Helical compression springs require little maintenance and allow for easy adjustment of the clamping force via the compression stroke. The spring travel of a helical compression spring is particularly well suited to compensating for length differences between the ceiling and floor.

[0024] The compression spring, particularly the helical compression spring, preferably has a long spring length, especially a spring length in the relaxed state of at least 100 mm, and particularly at least 200 mm. A particularly suitable helical compression spring can, in particular, have a spring length in the relaxed state between 250 mm and 300 mm, for example, 275 mm. The difference in length between the relaxed helical compression spring and the maximum compressed spring length is particularly at least 50 mm, particularly between 50 mm and 200 mm, and particularly between 50 mm and 150 mm, for example, about 90 mm. This ensures particularly reliable length compensation.

[0025] According to a preferred aspect of the awning system, the spring element is pre-tensioned in the clamping force direction. This pre-tension is independent of the installation condition, and in particular, independent of the insertion depth of the telescopic tube. The spring element can be pre-tensioned beyond this pre-tension during installation. The pre-tension of the spring element has the advantage that sufficient clamping force can be achieved even with minimal further compression of the spring element, especially with small adjustments to the clamping stroke. This simplifies installation.

[0026] The preload can be achieved in particular by pre-compressing the spring element, especially at least one spring component, for example at least one helical compression spring.

[0027] The clamping rod, and in particular the spring element, preferably has a preloading mechanism for preloading the spring element. The preloading mechanism can, for example, pre-compress at least one compression spring, in particular at least one helical compression spring. For example, the compression spring, in particular the helical compression spring, can be pre-compressed by respective axial stops, in particular end caps, of the preloading mechanism. For example, the compression spring, in particular the helical compression spring, can be mounted on a spring carrier that defines a maximum axial extension, for example by respective end caps.

[0028] Preferably, the spring element is designed such that elements arranged at its opposite axial ends, in particular the telescopic tube and the adjusting tube, are coupled to it in a rotationally fixed manner. This rotationally fixed coupling can be achieved, for example, by a spring carrier. This allows a torque to be transmitted from one component, for example, the telescopic tube, to the other component, for example, the adjusting tube.

[0029] According to a preferred aspect of the awning system, the spring element is pre-tensioned to at least 25%, and in particular at least 50%, of the target clamping force for clamping installation. This ensures that the target clamping force can be achieved during installation by slight further compression of the spring element, in particular of its helical compression spring. The clamping force is at least partially guaranteed even in the event of incorrect installation, for example, due to an insufficient clamping travel, which increases safety.

[0030] The target clamping force is the clamping force that should be achieved for clamping installation at the specific installation location. The target clamping force can be selected, for example, based on the wind resistance class of the awning and / or the maximum permissible point loads on the floor and / or ceiling. With correct installation, the target clamping force corresponds in particular to the clamping force present at a nominal distance between the ceiling and floor. Due to possible changes in the distance between the ceiling and floor, for example, caused by balcony flexion, the actual clamping force may vary after installation.

[0031] The target clamping force can be, for example, between 1,000 N and 3,000 N, in particular between 1,500 N and 2,500 N, for example approximately 2,100 N. Depending on the target clamping force, the spring element can, for example, have a preload between 375 N and 1,800 N. With a target clamping force of approximately 2,100 N, for example, a preload of at least 525 N, in particular at least 1,050 N, and in particular approximately 1,200 N, can be selected.

[0032] According to a preferred aspect of the awning system, the spring element of the at least one clamping rod is designed such that, in the assembled state of the awning system, the clamping force generated by the spring element varies by a maximum of 35%, and in particular by a maximum of 25%, when the spring element is deflected over a predetermined length compensation path. In particular, the distance between the floor and the ceiling can be variable, for example, due to vibrations of building components, such as cantilevered balconies. The spring element can be deflected by changing the distance between the floor and the ceiling. The length compensation path is determined, in particular, by a possible change, and especially by a maximum permissible change, in the distance between the ceiling and the floor. The length compensation path can be selected, in particular, based on the standards for vibrations of corresponding building components.The minimal variation in clamping force ensures that the awning remains securely mounted even if the building structure sways. The specified length compensation range can be, for example, between 1 cm and 5 cm, and in particular between 1.5 cm and 3.5 cm.

[0033] The variation in clamping force is specifically related to a target clamping force to be achieved. For example, with a target clamping force of 2,100 N, the clamping force can vary over a length compensation path by a maximum of 735 N, in particular by a maximum of 525 N, and in some cases by approximately 450 N.

[0034] Particularly preferably, the spring constant F of the spring element, especially for the spring constant of a helical compression spring of the spring element, is: F = D / mm, where D is a maximum of 3%, particularly a maximum of 2%, particularly a maximum of 1.5% of the nominal clamping force. The spring constant can, for example, be between 20 N / mm and 50 N / mm, for example approximately 30 N / mm.

[0035] According to a preferred aspect of the awning system, at least one of the contact surfaces of the clamping rod has an anti-slip component. Preferably, both contact surfaces of the clamping rod have an anti-slip component. The contact surfaces can, in particular, be formed by an anti-slip component, for example, an anti-slip disc. This increases the stability of the clamping assembly.

[0036] According to a preferred aspect of the awning system, the at least one clamping rod has an anchoring element in the area of ​​at least one of the contact surfaces for anchoring in the ceiling or floor. For example, the at least one clamping rod can have an anchoring element in the area of ​​the upper contact surface for anchoring in the ceiling. This further increases the stability of the installation. Due to the clamping installation, the anchoring element does not need to absorb axial forces, as is the case, for example, with known wall or ceiling brackets. The anchoring element only needs to be designed to absorb shear forces. For example, exactly one anchoring element, in particular a heavy-duty bolt, such as an M8 heavy-duty bolt, can be used.

[0037] According to a preferred aspect of the awning system, it features two clamping rods attached to the respective ends of the awning. The awning can, in particular, be mounted exclusively using these clamping rods.

[0038] Other uses of the clamping rod are possible, for example for mounting devices other than awnings.

[0039] Further features, details and advantages of the invention will become apparent from the following description of an exemplary embodiment with reference to the accompanying drawings. These show: Fig. 1 a perspective view of an awning system with an awning and two clamping rods for mounting the awning at an installation site, Fig. 2 a perspective view of one of the clamping rods of the awning system made of Fig. 1 , Fig. 3 an exploded view of the clamping rod made of Fig. 2 , Fig. 4 a longitudinal section through the clamping rod made of Fig. 2 before their installation between a floor and a ceiling, with a spring element of the clamping rod only partially shown in section for better illustration, Fig. 5 a detail V from Fig. 4 Fig. 6 shows a longitudinal section through the clamping rod, wherein a basic length of the clamping rod is adapted to a distance between floor and ceiling as far as possible by fixing a fixed end of the spring element at one of several axial positions; Fig. 7 shows a longitudinal section through the clamping rod, wherein a height-adjustable foot is unscrewed to compensate for a difference in length between the distance between floor and ceiling and the basic length of the clamping rod, so that the clamping rod stands without tension between floor and ceiling; Fig. 8 shows detail VIII from Fig. 7 , Fig. 9 a longitudinal section through the clamping rod, wherein the height-adjustable foot starting from Fig. 7 further unscrewed, so that the spring element is compressed by a clamping travel to generate a clamping force, Fig. 10 a detail X from Fig. 9 , and Fig. 11 a longitudinal section through a cover of the clamping rod with an anchoring element for anchoring the clamping rod in the ceiling.

[0040] In Fig. 1 An awning system 1 with an awning 2 is shown as an example. The awning 2 is a folding-arm awning in the form of a cassette awning. The awning 2 can be designed in a known manner. The awning 2 is attached to clamping rods 3 at its respective ends. The clamping rods 3 serve to clamp the awning 2 to a mounting location between a floor 4 and a ceiling 5.

[0041] With regard to the Fig. 2 bis 11 The clamping rods 3 and their assembly are described. For the sake of simplicity, a cover 6 present in the assembled state, which covers each foot 7 of the clamping rod 3, is omitted from the illustration. Fig. 2 bis 11 not shown.

[0042] In the present embodiment, the clamping rods 3 are identical, so the following description refers to a single clamping rod 3. In other embodiments, the clamping rods 3 can be configured differently. It is also possible to use only one clamping rod 3, which, for example, can be positioned in the center of the awning housing. It is also possible to combine a clamping rod 3 with other fastening means, for example, a clamping rod 3 at one end face of the awning 2 and a wall bracket at the other end face of the awning 2.

[0043] The clamping rod 3 has a housing tube 8, which in the present embodiment is designed as a round aluminum tube. A clamping unit 9 is mounted in the housing tube 8.

[0044] The clamping unit 9 has a spring element 10 with a helical compression spring 11. An adjusting tube 12 is arranged at a fixed axial end of the spring element 10. A telescopic tube 13 is arranged at a free end of the spring element 10 opposite the fixed end. The adjusting tube 12 and the telescopic tube 13 are connected axially via the spring element 10.

[0045] The adjusting tube 12 has a plurality of axially arranged adjusting bores 14. By inserting or withdrawing the clamping unit 9 into the housing tube 8, the adjusting bores 14 can each be aligned with a through bore 15 of the housing tube 8. A fastening element 16, for example in the form of a fastening clip, engages through the through bore 15 into the adjusting bore 14, which is then aligned with it, thus defining the axial relative position between the adjusting tube 12 and the housing tube 8. A basic length G (see figure) can be set in this way. Fig. 6 The basic length G is preferably selected such that it is slightly less than the distance A between the floor 4 and the ceiling 5. When adjusting the basic length G, it is not necessary to work against the spring force of the spring element 10.

[0046] With the aid of the fastening element 16, the fixed end of the spring element 10 can be indirectly attached to the housing tube 8 in different axial positions via the adjusting tube 12 and thus fixed in different axial positions.

[0047] The telescopic tube 13 is arranged at the free end of the spring element 10. Depending on the axial position of the fixed end of the spring element 10 and the compression state of the spring element 10, the telescopic tube 13 extends more or less into the housing tube 8. The telescopic tube 13 is thus telescopically mounted within the housing tube 8.

[0048] The foot 7 is located at the end of the telescopic tube 13 opposite the spring element 10. The foot 7 is height-adjustable and forms a length adjustment unit 17. For this purpose, a threaded rod 19 of the foot 7 is held in a retaining sleeve 18 of the telescopic tube 13. The threaded rod 19 can be screwed in or out of the retaining sleeve 18 for height adjustment via an adjusting nut 20. In the assembled state, the adjusting nut 20 is secured at the desired height by a lock nut 21.

[0049] The foot 7 forms a contact surface 22 for contact with the floor 4, wherein the contact surface 22 in the illustrated embodiment is designed as an anti-slip component.

[0050] The clamping rod 3 has a cover 23 at its axial end furthest from the base 7. The cover 23 closes the housing tube 8 at the top, with the housing tube 8 being received at its axial end in a tube receptacle 24 of the cover 23. In the assembled state, the clamping rod 3 is supported against the ceiling 5 by the cover 23. The cover 23 forms a contact surface 25 against the ceiling 5, which in the illustrated embodiment is designed as an anti-slip component.

[0051] The cover 23 has an anchoring bore 26 through which an optional anchoring element 27 can be inserted to anchor the cover 23 and thus the clamping rod 3 in the ceiling 5. The anchoring element 27 reliably prevents the clamping rod 3 from slipping relative to the ceiling 5. Since the clamping force is primarily applied by the spring element 10, the anchoring element 27 only needs to withstand shear forces, not axial forces. Therefore, the anchoring element 27 can be significantly less robust than that of conventional wall and ceiling brackets, which must withstand pull-out forces in the axial direction. For example, the anchoring element 27 can be designed as a single heavy-duty bolt, in particular a single M8 heavy-duty bolt. It is also possible to omit the anchoring element 27 altogether.

[0052] The spring element 10 comprises the helical compression spring 11 and a preload mechanism 28. The preload mechanism 28 has a spring carrier 29, for example, in the form of a square, which is surrounded by the helical compression spring 11. The axial ends of the helical compression spring 11 rest against axially displaceable end caps 31. The axial displacement of the end caps 31 is limited by clamping pins 30. The clamping pins 30 define a maximum axial distance between the end caps 31. The maximum axial distance of the end caps 31 is selected such that the helical compression spring 11 is compressed and thus preloaded. The preload is, in particular, at least 50% of a nominal clamping force.

[0053] The end caps 31 are connected to the adjusting tube 12 and the telescopic tube 13, respectively. In the illustrated embodiment, the end caps 31 are, for example, placed on the ends of the adjusting tube 12 and the telescopic tube 13 facing the spring element 10 and secured by a locking mechanism.

[0054] The adjusting tube 12 and the telescopic tube 13 are rotationally fixedly coupled via the spring element 10, in particular the spring carrier 29. This rotationally fixed coupling can be achieved, for example, via a spring carrier 29 designed as a square. The spring element 10, in particular the spring carrier 29, enables torque transmission from the adjusting tube 12 to the telescopic tube 13 and vice versa. This allows, for example, the rotational position of the adjusting tube 12 to be changed by rotating the telescopic tube 13. In this way, the angular position of the adjusting bores 14 relative to the through-hole 15 can be adjusted, for example, to achieve alignment for inserting the fastening element 16 after rotating the adjusting tube 12 relative to the housing tube 8.

[0055] The following describes the assembly of the clamping rod 3 using the Fig. 4 bis 10 described.

[0056] The clamping rod 3 is positioned at the installation site between the floor 4 and the ceiling 5. The clamping rod 3 is preferably provided in the shortest possible length to simplify transport. For this purpose, the fastening element 16 engages in the lowest adjustment bore 14 of the adjustment tube 12, so that the clamping unit 9 is inserted into the housing tube 8 as far as possible, as shown in Fig. 4 shown.

[0057] As in Fig. 6 As shown, the fastening element 16 is removed and the clamping unit 9 is pulled out of the housing tube 8 until the length of the clamping rod 3 essentially corresponds to a distance A between the floor 4 and the ceiling 5. The clamping unit 9 is then pushed back into the housing tube 8 until the next adjustment bore 14 aligns with the through bore 15. The fastening element 16 is then reinserted to fix the clamping rod 3 at the resulting basic length G. The basic length G is therefore less than the distance A.

[0058] The foot 7 is then adjusted in height using the length adjustment unit 17 until the resulting total length L of the clamping rod 3 corresponds to the distance A between floor 4 and ceiling 5. The clamping rod 3 is then free of tension between floor 4 and ceiling 5, as shown in the Fig. 7 and 8 The foot 7 extends beyond the telescopic tube 13 with an initial height h.

[0059] Subsequently, the foot 7 is screwed further out of the telescopic tube 13 using the length adjustment unit 17. The resulting mounting height H of the foot 7 is increased by a clamping travel S compared to the initial height h (see figure). Fig. 10 Since the total length L of the clamping rod 3 is limited by the distance A, increasing the height of the foot 7 causes the telescopic tube 13 to plunge further into the housing tube 8. This pushes the free end of the spring element 10 towards its fixed end, whose axial position in the housing tube 8 is fixed, cf. Fig. 9 This causes further compression of the helical compression spring 11, resulting in a clamping force with which the clamping rod 3 is held firmly between the floor 4 and the ceiling 5. The clamping travel S is selected such that, taking into account the preload of the spring element 10, a desired clamping force results.

[0060] Once the mounting height H is achieved, the adjusting nut 20 is secured by the lock nut 21.

[0061] The target clamping force can be selected based on the pull-out force to be withstood, for example, depending on the desired wind resistance class of the awning system 1. The pull-out force results from the awning's own weight 2 and any load from environmental influences, such as wind when the awning 2 is extended. The pull-out forces can be determined based on the desired wind resistance class of the awning 2. The pull-out force to be withstood can be increased by a safety factor based on the wind resistance class. The target clamping force is selected, in particular, so that it is less than the maximum permissible point load on the floor 4 and / or the ceiling 5.

[0062] The clamping force for mounting the awning system 1 is generated by the spring elements 10 of the clamping rods 3. This allows for flexible installation of the awning 2, particularly independent of further anchoring in the floor 4 and / or ceiling 5. Optionally, the cover 23 can be anchored in the ceiling 5 with the anchoring element 27 to compensate for lateral forces even more reliably. For this purpose, the cover 23 can be anchored in the ceiling 5 using the anchoring element 27, and the housing rod 8 can then be inserted into the tube receptacle 24.

[0063] Applying the clamping force using the spring element 10 also has the advantage that the spring element 10, in particular the helical compression spring 11, compensates for changes in length when the distance A between floor 4 and ceiling 5 changes. This can be particularly relevant for cantilevered balconies when they oscillate. For example, with balconies that cantilever significantly, such as those 2 m deep, oscillation can lead to a change in the distance A of up to 2 cm. When the distance A changes, the spring element 10, in particular the helical compression spring 11, is compressed or extended without the clamping rod 3 releasing.Preferably, the spring element 10, in particular the helical compression spring 11, is designed such that the clamping force generated by the spring element 10 varies by no more than 35% of the nominal clamping force over a predetermined length compensation path, over which the spring element 10 is deflected by a change in the distance A between the floor 4 and the ceiling 5. This can be ensured in particular by a sufficient length of the spring element 10, especially the helical compression spring 11.

[0064] The following are purely exemplary values ​​for spring element 10. The spring constant of the helical compression spring 11 is approximately 30 N / mm. In its relaxed state, the helical compression spring 11 has a spring length of approximately 275 mm. At its maximum compression, the helical compression spring 11 has a spring length of approximately 185 mm, with a spring force of approximately 2,700 N. In the pre-tensioned state of the spring element 10, the spring length of the helical compression spring 11 is approximately 235 mm and the pre-tension is 1,200 N. The nominal clamping force is 2,100 N, which corresponds to a spring length of approximately 205 mm.

[0065] For an exemplary, maximum possible change in the distance A between floor 4 and ceiling 5 of ± 15 mm, the clamping force varies by approximately ± 450 N. The minimum clamping force of approximately 1,650 N is designed to ensure the stability of the awning system 1 with a desired wind resistance class, for example, wind resistance class 2. The maximum clamping force of approximately 2,550 N is chosen to be lower than the maximum permissible point loads on floor 4 and ceiling 5.

2. Awning system according to Claim 1, characterised in that only the spring element (10) applies the clamping force.

3. Awning system according to one of the preceding claims, characterised in that the spring element (10) has at least one compression spring, in particular a helical compression spring (11).

4. Awning system according to one of the preceding claims, characterised in that the length adjustment unit (17) is designed to adjust an axial insertion depth of the telescopic tube (13) into the housing tube (8).

5. Awning system according to one of the preceding claims, characterised in that the spring element (10) is preloaded in the clamping force direction, in particular by means of a preload mechanism (28) of the spring element (10).

6. Awning system according to Claim 5, characterised in that the spring element (10) is preloaded to at least 25%, in particular at least 50%, of a setpoint clamping force for the installation by clamping.

7. Awning system according to one of the preceding claims, characterised in that the spring element (10) of the at least one clamping pole (3) is designed in such a way that, when the awning system (1) is installed, the clamping force produced by the spring element (10) varies by no more than 35%, in particular by no more than 25%, when the spring element (10) is deflected over a predetermined length compensation travel, by which in particular a distance (A) between the floor (4) and the ceiling (5) can be altered.

8. Awning system according to one of the preceding claims, characterised in that at least one of the contact surfaces (22, 25) of the clamping pole (3) has an anti-slip component.

9. Awning system according to one of the preceding claims, characterised in that the at least one clamping pole (3) has an anchoring element (27) in the region of at least one of the contact surfaces (22, 25) for anchoring in the ceiling (5) or floor (4).

10. Awning system according to one of the preceding claims, characterised in that the spring element (10) is designed in such a way that elements arranged at its opposite axial ends, in particular the telescopic tube (13) and an adjustment tube (12), are coupled thereby in a rotationally fixed manner.

11. Awning system according to one of the preceding claims, characterised by two clamping poles (3), which are attached to the respective end faces of the awning (2).
