Description

The present invention relates to an awning system with an awning, in particular an articulated arm awning. The awning system is suitable in particular for mounting on balances.Awnings, for example articulated arm awnings, are usually mounted with the aid of a wall or ceiling holder at the installation location, in particular on a balustrade. The holders can be acted upon by high pull-out forces which result from the dead weight of the awning and a load due to environmental influences, in particular wind when the awning is extended. This requires complex assembly. For example, anchoring with a plurality of heavy-duty dowels, in particular M12 heavy-duty dowels, per holder is required. This is relevant in particular for the articulated arm awnings in which the holders must withstand particularly high pull-out forces. The assembly, disassembly and / or a modification of the awning are made more difficult.It is therefore the object of the present invention to provide an awning system which enables a flexible and at the same time reliable mounting of the awning, in particular of an articulated arm awning, for example on balances.This object is achieved by a awning system having the features specified in claim 1. The awning system has an awning and at least one clamping rod for clampingly mounting the awning at a placement location between a floor and a ceiling, wherein the at least one clamping rod has in each case 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 with which the clamping rod is clamped between the floor and the ceiling in the mounted state. The awning is held in a simple and reliable manner by means of the clamping rod in a clamping manner between the floor and the ceiling. The application of the clamping force via the spring element has the advantage that a complicated anchoring in a wall or the ceiling which resists the pull-out forces of the awning is not required. The awning can thereby be mounted and disassembled in a simple and flexible manner. The awning is thus suitable in particular for mounting on balances.The clamping force required for holding the awning system is generated at least partially with the aid of the spring element. A spring tension of the spring element thereby causes the upper and the lower contact surface to press against the ceiling or floor. The at least one clamping rod is clamped between the floor and the ceiling. Advantageously, the spring element enables a flexible and simple adjustment of the clamping force effected thereby. The clamping force can be selected in particular depending on the pull-out force to be held, for example depending on a wind resistance class of the awning to be achieved. The wind resistance class can be determined, for example, according to DIN EN 13561. As an upper limit of the clamping force, in particular a maximum permissible point load of the floor and / or of the ceiling at the installation location can be selected.A further advantage is that the spring element enables length compensation. The clamping force generated by the spring element can also be maintained in the case of changes in length, for example because a distance between the floor and the ceiling varies. Unlike in the case of clamping rods without a spring element, the clamping force is not dependent on a precisely defined distance between the floor and the ceiling. This is especially important for mounting on evisceration balances. The latter can swing open, which can lead to a marked change in the distance between the floor and the ceiling.The awning is preferably an articulated arm awning, for example in the form of a cassette awning. Articulated arm awnings, in particular in comparison with window awnings, have particularly high extension forces, which makes their assembly more difficult. In particular, mounting with the aid of clamping rods for articulated arm awnings is only made possible by the spring element, since this ensures sufficient clamping forces reliably, in particular with simultaneously made possible length compensation.According to a preferred aspect of the awning system, the clamping force is applied exclusively via the spring element. This enables a particularly simple and precise setting of the clamping force independently of other, in particular rigid, clamping elements. In this way, in particular, a length compensation with varying distance between floor and ceiling is simplified.According to a preferred aspect of the awning system, the spring element has at least one compression spring, in particular at least one helical compression spring. The spring element may comprise one or more spring components. In particular, disk springs, helical springs and / or gas springs are suitable. Particularly preferably, the spring element has 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 are low-maintenance and allow simple adjustment of the clamping force over the compression path. The spring travel of a helical compression spring is particularly well suited for effecting a length compensation with varying distance between ceiling and floor.Particularly preferably, the compression spring, in particular the helical compression spring, has a long spring length, in particular a spring length in the relaxed state of at least 100 mm, in particular at least 200 mm. A particularly suitable helical compression spring can have, in the relaxed state, in particular a spring length of between 250 mm and 300 mm, for example 275 mm. A difference in length between relaxed helical compression spring and maximally compressed spring length is in particular at least 50 mm, in particular between 50 mm and 200 mm, in particular between 50 mm and 150 mm, for example approximately 90 mm. This ensures a particularly reliable length compensation.According to a preferred aspect of the awning system, the at least one clamping rod has a housing tube and a telescopic tube mounted axially displaceably therein, wherein the telescopic tube is arranged at a free end of the spring element. The spring element is compressed depending on an insertion path of the telescopic tube in the housing tube. This allows the clamping force to be adjusted easily and precisely and allows length compensation to be effected.The spring element is preferably mounted completely within the housing tube. As a result, the spring element is reliably protected against environmental influences and dirt.The housing tube can be, for example, an aluminum tube, in particular an aluminum round tube.According to a preferred aspect of the awning system, a fixed end of the spring element opposite the free end is fixed in its axial position with respect to the housing tube. This ensures that a compression path of the spring element and thus the clamping force achieved can be easily defined by the insertion path of the telescopic tube. Variation of the clamping force by displacing the fixed end of the spring element relative to the housing tube is avoided. The fixed end of the spring element can be fastened directly or indirectly to the housing tube.According to a preferred aspect of the awning system, the fixed end of the spring element can be fastened in different axial positions in the housing tube for adjusting a base length of the clamping rod. The clamping rod can be easily adapted to different installation locations, in particular to different distances between floor and ceiling.Preferably, the fixed end of the spring element is fastened indirectly to the housing tube via a length adjustment means. With the aid of the length adjustment means, the axial position of the fixed end of the spring element can be flexibly defined. A plurality of adjustment fastening receptacles, in particular adjustment bores, arranged in the axial direction have proven to be particularly suitable, in each of which adjustment fastening receptacles can engage. For example, the adjustment fastening receptacles, in particular adjustment bores, can be arranged in an adjustment tube which is arranged at the fixed end of the spring element, and / or in the housing tube. For example, the desired adjustment bore of an adjustment tube can be aligned with a through bore of the housing tube and fixed in the respective axial position by a fastening element. This enables a structurally simple and stable variation of the basic length of the clamping rod.It is also possible to provide a plurality of through-holes in the housing tube in order to make the length adjustment even more flexible.According to a preferred aspect of the awning system, the at least one clamping rod has a length adjustment unit for adjusting a tensioning distance by which the spring element is compressed given a total length of the clamping rod. This allows flexible adjustment of the clamping force independent of the overall length of the clamping rod. The total length of the clamping rod corresponds in particular to the distance between the floor and the ceiling. The length adjustment unit makes it possible in particular to set the clamping force independently of the distance between the floor and the ceiling. This advantageously facilitates the assembly, since for the assembly the clamping rod does not have to be compressed against the clamping force finally required. In particular, the clamping rod can first be placed tension-free between the floor and the ceiling in order to subsequently set the clamping force.The length adjustment unit can be designed in particular to adjust the axial position of the housing tube to the telescopic tube for a given overall length, in particular for a given distance between the ceiling and the floor. In this way, in particular, an insertion path of the telescopic tube can be varied in order to compress the spring element, in particular a helical compression spring of the spring element.According to a preferred aspect of the awning system, the length adjustment unit is designed as a height-adjustable foot, in particular for adjusting an axial insertion path of the telescopic tube into the housing tube. This enables a particularly easily accessible and adjustable adjustment of the clamping path. For example, the height-adjustable foot can be arranged at an end of the telescopic tube facing away from the spring element. By adjusting the length of the foot, in particular a height of the foot proceeding from the end of the telescopic tube, the telescopic tube is correspondingly axially displaced in the housing tube for a predefined total length. For example, the height-adjustable foot can be screwed in or out of the telescopic tube.A particular advantage of the height-adjustable foot is that the adjustable tensioning path correlates, in particular directly, with the height adjustment. The clamping path can be defined simply and precisely. For example, on the basis of a spring characteristic of the spring element, a desired clamping force to be achieved can be assigned to the respective clamping path or the respective height adjustment.According to a preferred aspect of the awning system, the spring element is prestressed in the clamping force direction. The prestress is in particular independent of an assembly state, in particular independent of an immersion path of the telescopic tube. The spring element can be prestressed beyond the prestress during assembly. The prestress of the spring element has the advantage that an adequate clamping force can be achieved even with a slight further compression of the spring element, in particular with a short length adjustment of the clamping path. This simplifies the assembly.The prestress can be effected in particular by precompressing the spring element, in particular at least one spring component, for example at least one helical compression spring.Particularly preferably, the clamping rod, in particular the spring element, has a prestressing mechanism for prestressing the spring element. The pretensioning mechanism can, for example, bring about a pre-compression of 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 precompressed by respective axial stops, in particular end caps, of the prestressing mechanism. For example, the compression spring, in particular the helical compression spring, can be mounted on a spring carrier which presets a maximum axial extent, for example by means of respective end caps.According to a preferred aspect of the awning system, the spring element is prestressed to at least 25%, in particular at least 50%, of a setpoint clamping force for the clamping mounting. This ensures that during assembly the desired clamping force to be achieved can be brought about by slight further compression of the spring element, in particular of a helical compression spring thereof. The clamping force is at least partially ensured even in the event of incorrect assembly, for example because an excessively short clamping travel has been set, which increases the safety.The target clamping force is the clamping force that is nominally to be achieved for clamping assembly at the particular site. The desired clamping force can be selected, for example, depending on a wind resistance class of the awning and / or on maximum permissible point loads of the floor and / or the ceiling. The desired clamping force corresponds, in the case of correct assembly, in particular to the clamping force which is present at a nominal distance between the ceiling and the floor. Due to possible changes in the distance between ceiling and floor, for example due to a swing of a balun, the actual clamping force may vary after assembly.The desired 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. The spring element can have, for example, a prestress between 375 N and 1,800 N, in particular depending on the desired clamping force. With a desired clamping force of approximately 2,100 N, a prestress of at least 525 N, in particular of at least 1,050 N, in particular of approximately 1,200 N, can be selected, for example.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 at most 35%, in particular at most 25%, when the spring element is deflected over a predefined length compensation path. In particular, a distance between the floor and the ceiling can be variable, for example on account of oscillations of building parts, for example of outcaking baluns. By changing the distance between the floor and the ceiling, the spring element can be deflected. The length compensation path is in particular predetermined by a possible change, in particular by a maximum permissible change, of the distance between ceiling and floor. The length compensation path can be selected in particular on the basis of the standards for oscillations of corresponding building parts. The slight variation of the clamping force ensures that the awning is securely mounted even when the building parts swing open. The predefined length compensation path can be, for example, between 1 cm and 5 cm, in particular between 1.5 cm and 3.5 cm.The variation of the clamping force is related in particular to a desired clamping force to be achieved. With an exemplary desired clamping force of 2,100 N, the clamping force can vary over a length compensation path by, for example, at most 735 N, in particular at most 525 N, for example by about 450 N.Particularly preferably for the spring constant F of the spring element, in particular for the spring constant of a helical compression spring of the spring element: F=D / mm, wherein D is a maximum of 3%, in particular a maximum of 2%, in particular a maximum of 1.5%, of the desired clamping force. The spring constant can be, for example, between 20 N / mm and 50 N / mm, for example, approximately 30 N / mm.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 installation surfaces can be formed in particular by a respective anti-slip component, for example an anti-slip roundde. This increases the stability of the clamping mounting.According to a preferred aspect of the awning system, the at least one clamping rod has an anchoring element in the region of at least one of the contact surfaces for anchoring in the ceiling or the floor. For example, the at least one clamping rod can have an anchoring element in the region of the upper contact surface for anchoring in the ceiling. This further increases the stability of the assembly. Due to the clamping mounting, the anchoring element does not have to absorb any axial forces, as is the case, for example, with known wall or ceiling holders. The anchoring element merely has to be designed to absorb transverse forces. For example, exactly one anchoring element, in particular a heavy-duty bolt, for example an M8 heavy-duty bolt, can be used.According to a preferred aspect of the awning system, it has two clamping rods which are fastened to the respective end sides of the awning. The awning can be mounted in particular exclusively by corresponding clamping rods.The invention has been described above using the example of an awning system with a clamping rod. However, the use of the clamping rod in an awning is not obligatory. The clamping rod can be an independent subject matter of the invention. Other uses of the clamping rod, for example for mounting devices other than awnings, are also possible.Further features, details and advantages of the invention are apparent from the following description of an exemplary embodiment with reference to the attached drawings. The following are shown: FIG. 1 shows a perspective view of an awning system with an awning and two clamping rods for mounting the awning at a set-down location, FIG. 2 shows a perspective view of one of the clamping rods of the awning system from FIG. 1, FIG. 3 is an exploded view of the clamping rod from FIG. 2, FIG. 4 shows a longitudinal section through the clamping rod from FIG. 2 before it is mounted between a floor and a ceiling, and wherein a spring element of the clamping rod is shown only partially in section for the sake of better illustration, FIG. 5 shows a detail V from FIG. 4, FIG. 6 shows a longitudinal section through the clamping rod, wherein a base length of the clamping rod is matched to a distance between floor and ceiling to the greatest extent by fixing a fixed end of the spring element at one of a plurality of axial positions, FIG. 7 is 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 the floor and the ceiling and the base length of the clamping rod, so that the clamping rod is free of tension between the floor and the ceiling, FIG. 8 shows a detail VIII from FIG. 7, FIG. 9 shows a longitudinal section through the clamping rod, wherein the height-adjustable foot is further unscrewed starting from FIG. 7, so that the spring element is compressed by a clamping path in order to generate a clamping force, FIG. 10 shows a detail X from FIG. 9, and FIG. 11 shows a longitudinal section through a cover of the clamping rod with an anchoring element for anchoring the clamping rod in the ceiling.FIG. 1 shows an example of an awning system 1 with an awning 2. The awning 2 is an articulated arm awning in the form of a cassette awning. The awning 2 can be designed in a manner known per se. The awning 2 is fastened at its respective end sides to clamping rods 3. The clamping rods 3 serve for clampingly mounting the awning 2 at a set-down location between a floor 4 and a ceiling 5.With reference to Figs. 2 to 11, the clamping rods 3 and their mounting will be described. A cover 6, which is present in the assembled state and covers in each case a foot 7 of the clamping rod 3, is not shown in FIGS. 2 to 11 for reasons of simpler illustration.In the present exemplary embodiment, the clamping rods 3 are each of the same design, so that the further description takes place with reference to a single clamping rod 3. In other exemplary embodiments, the clamping rods can be of different design. It is also possible to use only one clamping rod 3, which can be arranged, for example, centrally 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 holder at the other end face of the awning 2.The clamping rod 3 has a housing tube 8, which in the present exemplary embodiment is designed as an aluminum round tube. A clamping unit 9 is mounted in the housing tube 8.The clamping unit 9 has a spring element 10 with a helical compression spring 11. At a fixed axial end of the spring element 10, an adjustment tube 12 is arranged. At a free end of the spring element 10 opposite the fixed end, a telescopic tube 13 is arranged. The adjustment tube 12 and the telescopic tube 13 are connected in the axial direction via the spring element 10.The adjusting tube 12 has a plurality of adjusting holes 14 arranged in the axial direction. By inserting or extracting the clamping unit 9 into the housing tube 8, the adjustment bores 14 can each be arranged in alignment with a through bore 15 of the housing. By means of a fastening element 16, for example in the form of a fastening clip, which engages through the through bore 15 into the adjusting bore 14 which is then in alignment therewith, the axial relative position between the adjusting tube 12 and the housing tube 8 is fixed. In this way, a base length G (cf. FIG. 6 ) of the clamping rod 3 can be adjusted. The base length G is preferably selected such that the base length G is slightly smaller than a distance A between floor 4 and ceiling 5. When adjusting the base length G, work does not have to be performed against a spring force of the spring element 10.With the aid of the fastening element 16, the fixed end of the spring element 10 can be fastened indirectly via the adjustment tube 12 in different axial positions on the housing tube and can thus be fixed in different axial positions.The telescopic tube 13 is arranged at the free end of the spring element 10. Depending on an axial position of the fixed end of the spring element 10 and a compression state of the spring element 10, the telescopic tube 13 dips more or less into the housing tube 8. The telescopic tube 13 is thus mounted telescopically in the housing tube 8.The foot 7 is arranged 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 holding bushing 18 of the telescopic tube 13. By means of an adjusting nut 20, the threaded pin 19 can be removed from the holding bushing 18 or screwed into it for height adjustment. In the assembled state, the adjusting nut 20 is secured at the desired height by a counter nut 21.The foot 7 forms a contact surface 22 for contact with the floor 4, wherein the contact surface 22 is formed as an anti-slip component in the exemplary embodiment shown.The clamping rod 3 has a cover 23 at the axial end facing away from the foot 7. The cover 23 closes the housing tube 8 in an upward direction, wherein the housing tube 8 is accommodated with its axial end in a tube receptacle 24 of the cover 23. In the assembled state, the clamping rod 3 is supported on the ceiling 5 via the cover 23. The cover 23 forms an abutment surface 25 for abutment on the ceiling 5, which in the exemplary embodiment shown is formed as an anti-slip component.An anchoring bore 26 is formed in the cover 23, through which an optional anchoring element 27 for anchoring the cover 23 and thus the clamping rod 3 in the ceiling 5 can be guided. The anchoring element 27 reliably prevents the clamping rod 3 from slipping relative to the ceiling 5. The anchoring element 27 can thus be constructed to be substantially less strong than in the case of conventional wall and ceiling holders which have to absorb pull-out forces in the axial direction. For example, the anchoring element 27 can be designed as a single heavy-load bolt, in particular as a single M8 heavy-load bolt. It is also possible to dispense with the anchoring element 27.The spring member 10 includes the compression coil spring 11 and a biasing mechanism 28. The pretensioning mechanism 28 has a spring carrier 29 which is designed, for example, as a square and which the helical compression spring 11 surrounds. The axial ends of the helical compression spring 11 bear against axially displaceable end caps 31. Axial displaceability of the end caps 31 is limited by clamping pins 30. The clamping pins 30 define a maximum axial distance of the end caps 31 from one another. The maximum axial distance of the end caps 31 is selected such that the helical compression spring 11 is compressed and thus prestressed. The prestress is in particular at least 50% of a desired clamping force.The end caps 31 are connected to the adjustment tube 12 and the telescopic tube, respectively. In the exemplary embodiment shown, the end caps are, for example, plugged onto the ends of the adjustment tube 12 or of the telescopic tube 13 facing the spring element 10 and fastened via a latching mechanism.The mounting of the clamping rod 3 is described below with reference to FIGS. 4 to 10.The clamping rod 3 is provided at the installation location between the floor 4 and the ceiling 5. The clamping rod 3 is preferably provided with the smallest possible length, which simplifies the transport. For this purpose, the fastening element 16 engages in the lowermost adjustment bore 14 of the adjustment tube 12, so that the clamping unit 9 is inserted as far as possible into the housing tube 8, as shown in FIG. 4.As shown in FIG. 6, the fastening element 16 is removed and the clamping unit 9 is pulled out of the housing tube 8 until a length of the clamping rod 3 substantially corresponds to a distance A between the floor 4 and the ceiling 5. Subsequently, the clamping unit 9 is inserted into the housing tube 8 until the next adjustment bore 14 is aligned with the through bore 15. The fastening element 16 is then inserted again for fixing the clamping rod 3 in the resulting base length G. The base length G is thus smaller than the distance A.Subsequently, the foot 7 is adjusted in height with the aid of the length adjustment unit 17 in such a way until a resulting total length L of the clamping rod 3 corresponds to the distance A between the floor 4 and the ceiling 5. The clamping rod 3 is then free of stress between the floor 4 and the ceiling 5, as is shown in FIGS. 7 and 8. The foot 7 projects here with an initial height h beyond the telescopic tube 13.Subsequently, the foot 7 is further unscrewed from the telescopic tube 13 with the aid of the length adjustment unit 17. The resulting mounting height H of the foot 7 is increased by a tensioning distance S relative to the starting height h (cf. FIG. 10 ). Since the total length L of the clamping rod 3 is limited by the distance A, an increase in the height of the foot 7 causes the telescopic tube 13 to be further inserted into the housing tube 8, which pushes the free end of the spring element 10 towards its fixed end, the axial position of which is fixed in the housing tube 8, see FIG. 9. The clamping path S is selected here such that a desired clamping force results taking into account the prestress of the spring element 10.When the mounting height H is reached, the adjusting nut 20 is secured by the counter nut 21.The desired clamping force can be selected in particular depending on the pull-out force to be held, for example depending on a wind resistance class of the awning system 1 to be achieved. The pull-out force results from the dead weight of the awning 2 and a load due to environmental influences, for example wind when the awning 2 is extended. The pull-out force to be held can be increased by a safety factor, starting from the wind resistance class. The desired clamping force is selected in particular such that it is smaller than a maximum permissible point load of the floor 4 and / or of the ceiling 5.The clamping force for mounting the awning system 1 is effected by the spring elements 10 of the clamping rods 3. This allows flexible raising of the awning, in particular independently of further anchoring in the floor 4 and / or ceiling 5. Optionally, the cover 23 can be anchored with the anchoring element 27 in the ceiling 5, in order to even out transverse forces even more reliably. For this purpose, the cover 23 can be anchored in the ceiling 5 with the aid of the anchoring element 27 and the housing rod 8 can subsequently be inserted into the pipe receptacle 24.The application of the clamping force with the aid of the spring element 10 also has the advantage that the spring element 10, in particular the helical compression spring 11, brings about a length compensation when the distance A between the floor 4 and the ceiling 5 changes. For example, in the case of heavily carving baluns, for example baluns 2 m deep, a ringing-up can lead to a change in the distance A of up to 2 cm. When the distance A is changed, the spring element 10, in particular the helical compression spring 11, is compressed or pulled apart without the clamping rod 3 being released. The spring element 10, in particular the helical compression spring 11, is preferably designed in such a way that the clamping force generated by the spring element 10 varies by at most 35% of the desired clamping force over a predefined 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 over a sufficient length of the spring element 10, in particular of the helical compression spring 11.Purely exemplary values for the spring element 10 are given below. The spring constant of the helical compression spring is about 30 N / mm. The helical compression spring 11 has a spring length of approximately 275 mm in the relaxed state. At block (maximum compression), the helical compression spring 11 has a spring length of about 185 mm, the spring force being about 2,700 N. In the prestressed state of the spring element 10, the spring length of the helical compression spring 11 is approximately 235 mm and the prestress is 1,200 N. The setpoint clamping force is 2,100 N, which corresponds to a spring length of approximately 205 mm.In the case of an exemplary maximum possible change of ±15 mm in the distance A between the floor 4 and the ceiling 5, the clamping force varies by approximately ±450 N. The minimum clamping force of approximately 1,650 N is dimensioned in such a way that the stability of the awning system 1 is ensured with a desired wind resistance class, for example the wind resistance class 2. The maximum clamping force of about 2,550 N is selected to be smaller than the maximum permissible point loads of the floor 4 and the ceiling 5.
