Description

[0001] awning

[0002] The invention relates to an awning with a rotatably mounted fabric shaft, an awning fabric, a projection rod and at least one driven, multi-section telescopic arm, wherein the awning fabric is connected to the fabric shaft in the region of an inner fabric edge and to the projection rod in the region of an opposite outer fabric edge, wherein the projection rod can be adjusted by means of the telescopic arm between a retracted position, in which the awning fabric is preferably completely wound onto the fabric shaft, and an extended position, in which the awning fabric is preferably completely stretched out, wherein the telescopic arm has at least two arm sections, wherein an electrical consumer is arranged on the telescopic arm and / or on the projection rod and is connected to an electrical voltage source via an electrical power line, and wherein the electrical power line runs at least in sections within the telescopic arm.

[0003] An awning of the above-mentioned design is known and can be designed as an open awning or as a so-called box or cassette awning in which the fabric shaft is accommodated in a box-shaped housing. To adjust the projection rod, at least two multi-section, driven telescopic arms are usually used which are pre-tensioned by springs, for example gas springs, or are adjustable by hydraulic or pneumatic piston-cylinder units. When the awning is in its retracted position, in which the fabric is wound onto the fabric shaft, the projection rod is close to the fabric shaft and is held in this position by the tension of the awning fabric. When the tension of the awning fabric is reduced by rotating the fabric shaft, the projection rod is moved away from the fabric shaft as a result of the pre-tensioned telescopic arms, whereby the awning fabric is unwound from the fabric shaft and stretched out.

[0004] It is known to arrange an electrical consumer, for example in the form of a fan or a lighting device, on the telescopic arm and in particular on the drop rod. In order to supply the electrical consumer with electrical energy, in many cases an electrical voltage source, for example a battery, is arranged directly on the drop rod. This has the disadvantage that only an electrical consumer can be connected which has a relatively low power consumption, since otherwise the battery is not sufficient. In particular, electrical consumers with a high power consumption, for example radiant heaters or an air conditioning system, cannot be operated in this way. Such electrical consumers must be connected directly to a socket and thus to the public power grid.It is known to attach a corresponding power cable to the outside of the telescopic arm, which is, however, aesthetically unsightly and entails the risk that the power cable may be damaged by external weather influences and external influences from animals.

[0005] DE 10 2006 001 332 A1 discloses the use of a power cable within the telescopic arm. It has been shown that with extended use of such an awning, there is a risk of the power cable becoming twisted, which not only poses a risk of damage to the power cable but also impairs the awning's adjustment function.

[0006] The invention is based on the object of creating an awning of the type mentioned, in which an electrical power line and in particular a power cable is accommodated safely and reliably in the telescopic arm.

[0007] This object is achieved according to the invention by an awning having the features of claim 1. It is provided that a guide device is formed in the telescopic arm, by means of which the electrical power line is guided laterally.

[0008] According to the invention, the electrical power line runs at least partially and preferably completely within the telescopic arm and preferably penetrates the entire telescopic arm.

[0009] The arrangement of the power cable within the telescopic arm ensures that it is reliably protected from external environmental influences and damage caused by animals. This guarantees a long service life for the power cable.

[0010] By means of the guide device, the electrical power line and in particular the power cable takes up a predetermined position within the telescopic arm, so that a reliable and safe positioning of the cable within the telescopic arm is ensured.

[0011] Preferably, the guide device extends in the longitudinal direction of the telescopic arm over at least part of its axial length and in particular over the entire axial length.

[0012] The telescopic arm has at least two arm links and in particular at least three arm links. A first arm link is designed as a hollow profile and a second arm link is inserted into the first arm link with a close fit so that it can be moved in the longitudinal direction of the latter and retracted into the first arm link. The second arm link is also designed as a hollow profile and can accommodate a third arm link so that the third arm link can be retracted into the second arm link in the longitudinal direction of the latter. The third arm link can also be designed as a hollow profile. The design of all arm links as a hollow profile has the advantage that the power line can be easily guided through the interior of the arm links, which form an internal cable duct.

[0013] The telescopic arm preferably has a first end piece at its end facing the fabric shaft, which can be attached to the first arm link, for example. Furthermore, the telescopic arm has a second end piece at its opposite end facing the drop-out rod, which second end piece can be attached to the third arm link, for example. In a further development of the invention, it is provided that the electrical power line runs from the first end piece to the second end piece inside the telescopic arm, wherein the power line can penetrate the first end piece and / or the second end piece. Furthermore, it can be provided that the power line ends in a plug or a socket at the first end piece and / or the second end piece, so that the power line can be easily connected to further power lines and, if necessary, can be easily disconnected, for example if the telescopic arm has to be replaced.

[0014] In one possible embodiment of the invention, at least one of the arm members, and preferably all of the arm members, has a downwardly tapered cross-section. The cross-section can be, for example, triangular or trapezoidal.

[0015] This is particularly advantageous if, in a preferred embodiment of the invention, the power line is formed by a cable. In particular, due to its own weight, the cable falls downwards within the cross-section of the telescopic arm and is then arranged in the tapered region of the cross-section. In a preferred embodiment of the invention, provision is made for the cable, due to its own weight, to be accommodated with a fit in the lower section of the cross-section of the arm members, so that reliable and secure positioning of the cable within the telescopic arm is ensured by the wall of the telescopic arm. The wall of the telescopic arm serves as a laterally supporting guide device.

[0016] Alternatively or additionally, at least one of the arm members may have, in a lower region of its cross-section, a guide channel defined by side walls, in which the electrical power line or power cable is accommodated at least in sections. The guide cable is preferably dimensioned such that the power line or power cable is accommodated therein with a fit, in particular with a tight fit.

[0017] The cable must be designed to accommodate the telescopic movement of the telescopic arm. If a standard power cable is used, the length of the power cable within the telescopic arm must be selected so that the power cable is not subjected to excessive tension and damage, even when the telescopic arm is fully extended and thus at its maximum length. When the telescopic arm is retracted, the cable within the telescopic arm forms defined loops thanks to the guide device.

[0018] Preferably, the cable is a so-called spiral cable or a coiled cable. Such a cable can be lengthened under elastic deformation and can thus follow the extension movement of the telescopic arm. When the telescopic arm is retracted, the cable returns to its original position as a result of the spring force or restoring force caused by the elastic deformation. When using a coiled cable or a spiral cable, the guide device reliably ensures the desired positioning of the cable within the telescopic arm.

[0019] In a further development of the invention, at least one partition wall and preferably several partition walls can be provided in the telescopic arm, which preferably run perpendicular to the longitudinal direction of the telescopic arm or arm members. The partition walls each have at least one opening through which the cable is passed, the opening serving to position the cable and to guide the cable.

[0020] As an alternative embodiment of the power line, conductor tracks can be provided that are formed on the inside and / or outside of the arm links. The conductor tracks are electrically connected to one another in every position of the arm links. For this purpose, contact elements are provided, which can be, for example, sliding contacts or contact slides, and which connect the conductor tracks.

[0021] Due to the aforementioned design of the power line, it is possible to supply the electrical load with sufficient electrical energy. The electrical load can be, for example, a heating device, in particular a radiant heater, and / or a lighting device, for example a spotlight or a strip light, and / or a fan and / or an air conditioning system and / or a sound system, in particular for music playback.

[0022] Further features and advantages of the invention will become apparent from the following description of an embodiment with reference to the drawings. In the drawings:

[0026] Fig . 5 an alternative cross-sectional shape of the telescopic arm and

[0027] Fig. 6 is a perspective view of an alternative embodiment of the telescopic arm.

[0028] Fig. 1 shows a schematic perspective view of a telescopic arm awning 10, which has a usually horizontally aligned fabric shaft 11, which is mounted on end fabric shaft holders 12 so as to be rotatable about a longitudinal axis A. An awning fabric 15 is fastened to the fabric shaft 11 with an inner end facing the fabric shaft 11 and can be wound onto it and unwound from it. At the opposite end, the awning fabric 15 is connected to a projection rod 16 which runs parallel to the fabric shaft 11 and in particular horizontally. The projection rod 16 is held on a holding device 17 via two multi-part, driven and in particular spring-loaded telescopic arms 14. The holding device 17 is attached to a supporting structure 18, which in the illustrated embodiment is formed by a supporting tube 13, which can be firmly attached, for example, to a building or a substructure.As a result of an extension movement of the two telescopic arms 14, the projection rod 16 can be moved away from the fabric shaft 11, whereby the awning fabric 15 is unwound from the fabric shaft 11 and stretched. Accordingly, the awning fabric 15 can be wound onto the fabric shaft 11 by means of the telescopic arms 14 by retracting the projection rod 16 in the direction of the fabric shaft 11.

[0029] An electrical load 19, indicated only schematically, is arranged on the extension rod 16. This load may be, for example, a lighting device. The electrical load 19 is connected to an electrical voltage source 21, indicated only schematically and which may be the public power grid or a storage battery, via a power line 20. As indicated schematically in Fig. 1, the power line 20 runs within one of the telescopic arms 14.

[0030] Fig. 2 shows a perspective view of a telescopic arm 14. The telescopic arm 14 has a first arm member 14.1, which is designed as a hollow profile and carries a first end piece 23 at its one end, the left end as shown in Fig. 2, by means of which the telescopic arm 14 can be pivotally mounted on the holding device 17.

[0031] A second arm link 14.2 is designed in such a way that it can be inserted into the first arm link 14.1 with a tight fit and can be retracted into it along the first arm link 14.1.

[0032] The 2nd arm link 14.2 is also designed as a hollow profile and can accommodate a 3rd arm link 14.3 with a tight fit so that the 3rd arm link 14.3 can be retracted into the 2nd arm link 14.2.

[0033] The 3rd arm link 14.3 is also preferably designed as a hollow profile and carries a 2nd end piece 24 at its right end facing away from the 2nd arm link 14.2, as shown in Fig. 2, via which the telescopic arm 14 can be connected in an articulated manner, for example to the drop rod 16.

[0034] Fig. 3 shows the telescopic arm 14 according to Fig. 2 without the two end pieces 23 and 24. Since the arm links 14.1, 14.2, and 14.3 are each designed as a hollow profile, the arm links 14.1, 14.2, and 14.3 can form an inner cable channel 22 extending over the entire length of the arm links, into which an electrical power line 20 in the form of a spiral cable or a coiled cable 25 is inserted. The arm links 14.1, 14.2, and 14.3 have a downwardly tapered cross-section that approximates a stylistic heart shape. Due to its own weight, the cable 25 rests in the lower section of the tapered cross-section of the arm links 14.1, 14.2, and 14.3. The lateral walls of the cross-section of the telescopic arm 14 are designed to form a guide device 32 for the cable 25.

[0035] Fig. 4 shows a cross-section through the telescopic arm 14. It can be seen that, at least in the third arm section 14.3, which has the smallest dimensions of the arm sections 14.1, 14.2, and 14.3, a partition wall 26 is arranged, extending transversely to the longitudinal extent of the arm sections 14.1, 14.2, and 14.3. The partition wall 26 has several openings 27, with the cable 25 being guided through the lower opening 27, whereby the opening 27 serves as a cable guide and for positioning the cable 25.

[0036] Figure 5 shows an alternative cross-sectional design of the telescopic arm 14, which in the example shown has a rectangular cross-section. To form a guide device 32 for the cable 25, two spaced-apart side walls 31 are provided on the base of the cross-section of the telescopic arm 14 within the latter. These side walls form a guide channel 33 extending in the axial longitudinal direction of the telescopic arm 14, into which the cable 25 is inserted.

[0037] Fig. 6 shows an alternative embodiment of the power line 20. The telescopic arm 14 has the same basic structure with the three interlocking arm members 14.1, 14.2, and 14.3. Each arm member 14.1, 14.2, and 14.3 carries, on the inside and / or outside of the line channel 22, a conductor track 28, 29, 30 extending in the longitudinal direction of the arm member 14.1, 14.2, 14.3, which can be formed, for example, by an applied metallic strip, in particular a copper strip. Adjacent conductor tracks 28, 29, 30 are electrically connected via a contact element 31, which is only schematically indicated and which can be, for example, a sliding contact or a contact slide, so that in every relative position of the arm members 14.1, 14.2, 14.3 there is a continuous current line inside the telescopic arm 14.
