Description

[Technical Field]

[0001] The present invention relates to a sunshade for a camper, in particular a manually operable sunshade comprising a sunshade cloth, a sunshade roller capable of rolling up the sunshade cloth, and at least two sunshade arms. [Background technology]

[0002] Awnings of this type are known in many configurations. For example, German Utility Model No. 202014104014 discloses such a sunshade. In such sunshades, the sunshade is typically permanently attached to a vehicle, in particular a camper van, by means of a housing. To assemble the sunshade, the base frame, in particular the sunshade arms acting as rafters and the optional sunshade legs serving to support the free ends of the sunshade arms on the base, are first removed from the housing and assembled as separate, individual components. The sunshade fabric wound up on the sunshade roller can then be manually, i.e., by hand, unrolled toward the free ends of the sunshade arms and attached to the free ends of the sunshade arms by one end, often the sunshade roller itself.

[0003] To allow for a variety of depths, also referred to as extension lengths, shade arms can often be assembled in different lengths, and for this purpose each shade arm may include multiple sections or elements that can be positioned and attached in different positions relative to one another, resulting in different lengths for the shade arm as a whole.

[0004] It has been found that camping today is no longer undertaken in one place for a relatively long period of time, but rather in much shorter intervals, i.e., a large number of short stays or overnight stays in many different locations, sometimes even in places that are preferably closer to nature and harder to reach. This has led to a great demand for sunshades that can be quickly and easily set up and taken down.

[0005] However, with typical sunshades, assembly and disassembly are often relatively time-consuming and complicated. Furthermore, the manufacturing costs of such sunshades, which consist of a large number of individual components, are often relatively high. For example, assembling such sunshades typically requires that all of the individual components must first be manually removed from their respective storage containers or storage housings, temporarily placed next to the vehicle, and then aligned, interlocked, and / or attached to one another in turn to ultimately form the base frame. When disassembling the sunshade, the same applies in reverse, and in this case, the user must often take care to ensure that the individual components of the sunshade fit back into their assigned storage locations due to dimensional design.

[0006] Furthermore, after assembly, adapting or adjusting such awnings is often only possible with a relatively large amount of effort. For example, with such awnings, the depth of the awning, particularly the length of the awning arms, is determined in one of the initial assembly steps and often cannot be changed after assembly, or can only be changed with considerable effort. For example, to change the length of the awning arms, it is usually necessary to partially disassemble the awning, particularly to separate the attachment points of the awning fabric from the free ends of the awning arms and at least partially wind the awning fabric onto the awning rollers. Then, to avoid distortion of the awning legs, the length of each individual element of the awning arm can be changed and locked together in the new position while simultaneously lifting the entire base frame. The awning fabric can then be unwound and attached to the newly positioned free ends of the awning arms. Therefore, such post-adjustment usually requires at least two people.

[0007] Furthermore, today, the criterion of vehicle energy efficiency is becoming increasingly important, especially with regard to the wind resistance of the vehicle. Therefore, it is worth pursuing to design not only the vehicle itself, but also the attachments attached to the exterior of the vehicle, so that they have as little wind surface as possible when the vehicle is moving, and thus do not undesirably increase the overall wind resistance of the vehicle. A disadvantage of many sunshades from the prior art is the often relatively bulky and large structural form of those sunshades, especially the sunshade housing. Summary of the Invention [Problem to be solved by the invention]

[0008] The object of the present invention is therefore to provide a sunshade which remedies at least one of the above-mentioned drawbacks and in particular allows for particularly easy assembly and dismantling of the sunshade as well as quick and simple post-adjustment, while at the same time allowing for a relatively compact construction type. [Means for solving the problem]

[0009] The present invention solves the problem posed by a sunshade having the features of the main claim. Advantageous configurations and refinements of the invention are disclosed in the dependent claims, the description and the drawings.

[0010] According to the invention, the awning rollers and / or awning arms are suitably designed to pretension the awning fabric. In particular, the awning fabric can be tensioned to the desired position automatically by the pretensioning means or by manual pretensioning and locking. This makes it particularly easy to unwind and retract the awning fabric, especially during assembly, disassembly, and re-adjustment of the awning. In particular, the awning fabric can automatically adapt to the respective changes in length of the awning arms, especially when shortening the awning arms. For this purpose, the pretensioning means can be embodied, for example, as a spring, which can be arranged on the awning rollers and / or awning arms. The awning arms are preferably pivotally mounted in a awning housing that is permanently attached to the camper van. For this purpose, the awning housing is preferably made of aluminum.

[0011] In this context, pretensioning means applying a force to the shade cloth so that it is tensioned with only a small amount of downward slack, which can be achieved in particular by pressing individual sections of the shade cloth away from each other, for example between the shade housing and the free end of the shade cloth or the shade roller.

[0012] In this specification, manual operation means, in particular, manual assembly or disassembly without the assistance of a prime mover. For example, with respect to a shade cloth, manual operation means, in particular, manual pulling out of the shade cloth and locking of the shade roller, or manual separation of the shade roller and winding of the shade cloth onto the shade roller.

[0013] In one embodiment of the invention, the awning roller and / or the awning arm each have a pretensioning means for pretensioning the shade cloth. This allows for automatic pretensioning. The pretensioning means may, for example, be configured as a spring. The spring may be arranged on the awning roller and / or the awning arm. If the pretensioning means is provided on the awning roller, the shade cloth is preferably pretensioned in the direction of winding up the shade cloth onto the awning roller. If the pretensioning means is provided on the awning arm, the shade cloth is preferably pretensioned in the direction of the free end of the awning arm. Pretensioning, in particular automatic pretensioning, is preferably performed not only in the assembled awning, but also during assembly and dismantling, in particular while the shade cloth is being unwound from and wound onto the awning roller. This allows for particularly simple assembly and dismantling of the awning.

[0014] In order to pretension the shading cloth and / or the shading rollers, it may be provided that the shading arms are variable in length. In particular, the shading arms may consist of several elements that are slidable or telescopic relative to one another, so that a predefined arm length and thus the individual depth of the shading can be adjusted by the shading arms. In this case, the shading cloth can be at least temporarily fixed at one free end of each shading arm and can be pretensioned by the variable length of the shading arms. This makes it particularly easy to change the size of the shading, especially in the depth direction. This also applies in particular to when the shading is already fully assembled.

[0015] It is preferred that a coupling device, in particular a coupling device configured as a bayonet pin, is arranged at one longitudinal end of the shading arm for connecting a section of the front strip that supports and / or supports the shading roller, in each case, in order to pretension the shading cloth and / or the shading roller.In particular, it may be specified that in a first configuration the shading roller is permanently arranged in the region of the end face of the shading arm facing the camper, and that the shading cloth extends above this arm as far as the end face facing away from the camper, in particular the free end of the shading arm, and can be connected to the shading arm in this region. In an alternative configuration, it may be specified that the shade roller is removable from the shade housing (preferably permanently attached to the camper van), the shade cloth is permanently attached with one end to the shade arm in the region of the end face facing the camper van (in particular to the shade housing) and extends to the shade roller, which can be at least temporarily fixed to the shade arm by means of a coupling device arranged at the free end of the shade arm, thereby making it particularly easy to at least temporarily attach the shade cloth and / or the shade roller to the end face end of the shade arm and then to completely assemble the shade (in particular by extending the shade arm).

[0016] The sunshade arms are preferably each telescopically extendable and may for this purpose have a first arm section, also called first arm element, and at least one second arm section, also called second arm element, which can be telescopically extended in its longitudinal direction relative to the first arm section. Particularly preferably, the second arm section can be pushed into the cavity formed by the first arm section, in other words, inside the first arm section. This allows the sunshade arms to be designed particularly compact and space-saving, and therefore particularly easy to handle.

[0017] In one advantageous embodiment of the invention, a locking system is provided for blocking telescopic extension, or in other words, for blocking the relative movement of at least the second arm segment relative to the first arm segment in at least one of the two possible directions of movement in the longitudinal direction. The locking system is particularly configured to block the extension of the shading arms, in particular the sliding of the at least two arm segments away from each other, or the shortening of the shading arms, in particular the pressing of the at least two arm segments toward each other, or both. The blocking can be achieved, for example, by one or more contact surfaces engaging with each other. This allows the shading arms to be particularly easily aligned with each other and to provide a particularly reliable pretensioning of the shading cloth.

[0018] Preferably, the locking system is configured so that the blocking of the telescopic extension and retraction of the second arm section relative to the first arm section only applies to one of the two possible directions of movement in the longitudinal direction, in particular against shortening of the shading arms, i.e. against squeezing or pressing together of the telescopic arm sections, thereby effectively preventing the shading arms from being pressed together or shortened due to pretensioning caused by an already installed shading cloth, for example during assembly or re-adjustment of the shading.

[0019] In one advantageous configuration, the locking system is arranged between the first and second arm segments, in particular on the outer surface of the inner arm segment. Particularly preferably, the locking system is arranged between the inner surface of the first arm segment and the outer surface of the second arm segment, in particular the outer surface facing the inner surface of the first arm segment. This configuration allows for a particularly compact construction of the awning arm and easy and reliable handling when extending and retracting the awning arm.

[0020] The locking system may be configured such that the blocking action is triggered automatically, in particular when the arm sections are pulled relative to one another. In this context, automatic triggering means, in particular, triggering without manual intervention. Automatic triggering may occur, for example, by a first blocking means engaging one of a corresponding plurality of second blocking means, thereby blocking further movement of the arm sections relative to one another.

[0021] Particularly preferably, the locking system comprises a locking device acting in one direction of movement, preferably exclusively in one direction of movement, in which case the first blocking means may be configured as a first locking part and the second blocking means as a second locking part, and these locking parts may be configured to act exclusively in one direction of movement.

[0022] For example, the locking device may include a rack arranged on one of the arm sections and having a plurality of beveled teeth, each of which has a locking surface facing the other of the arm sections, and a locking tongue or lever arranged on the other of the arm sections and having a locking protrusion that slides freely over the beveled teeth when the arm sections are telescopically pulled out from one another and that can engage with the locking surface of one of the beveled teeth with its locking side when the arm sections are telescopically pushed in and out from one another, thus blocking movement. This makes handling such sunshades particularly user-friendly during assembly and removal as well as re-adjustment, since, for example, the blocking action can be triggered automatically.

[0023] The locking device may be configured such that one section of the locking tongue can be pressed against a spring toward the rack to separate the locking side from the locking surface, so that the opposite section of the locking tongue with the protrusion is lifted off the rack, or the locking tongue can be displaced toward the locking surface to separate the locking side from the locking surface. Such a configuration allows for particularly simple operation, in particular for releasing the blocking effect of the locking system, which can be advantageous above all when removing and re-adjusting the sunshade. For pressing, the locking tongue can have a surface or contour that is ergonomically adapted to the finger, for example, so that the locking tongue can be particularly easily operated.

[0024] In one refinement of the locking system, it can be specified that the locking device additionally comprises an actuating member that can be slid, in particular in the longitudinal direction of the awning arm, and that this actuating member is operatively connected to the locking tongue via a wedge-shaped connection, in such a way that sliding the actuating member in the direction of the locking tongue presses the locking tongue away from the rack. This allows the locking system, and ultimately the entire awning arm, to be particularly compact. The actuating member can, for example, be designed as a flat sliding element that is arranged to be slidable by a finger, in particular the thumb. This allows for particularly simple operation of the locking system.

[0025] It is particularly preferred that at least a substantial section of the actuating member is arranged between the locking tongue and the rack. In particular, the actuating member can be guided in one direction, in particular in the sliding direction, between the locking tongue and the rack. This results in a particularly flat design of the locking system. Furthermore, it can be specified that the locking tongue and / or the actuating member extend at least partially, preferably completely, around the outer circumferential surface of the shade arm on the outside. This makes it possible to design the locking tongue particularly stable, and to grip and slide the actuating member particularly reliably and easily by hand.

[0026] In one refinement of the locking system, it may be provided that the locking system is always, in particular in all operating states, arranged inside the projected outer peripheral contour of the shade arm, preferably of the outer arm section, so that the shade arm has a particularly compact design and therefore the entire shade housing can be made particularly compact.

[0027] In one advantageous embodiment of the invention, the awning additionally has awning legs. Preferably, the awning has the same number of awning legs as the awning arms. This allows each awning arm to be supported by a awning leg. In this case, when the awning is assembled, the awning legs may be arranged at the free ends of the awning arms facing away from the campervan. In particular, to adjust the awning to a suitable height, the awning legs are preferably designed to be variable in length, in particular telescopically extendable. This allows adjustment to unevenness in the base and various desired heights of the awning fabric.

[0028] The length-adjusting means and locking means of the awning legs may be configured similarly to the awning arms, particularly in terms of their structural and functional configuration. It will be apparent that the awning legs may each have a locking system, particularly as described above for the awning arms. In particular, the awning legs may also have a locking system that can produce a blocking action in the direction of pressing together, so that each leg can be locked at its own length. In this case too, the locking system may be configured as a locking device, particularly as described above. Preferably, the blocking action is possible in both directions of movement in the longitudinal extension of the legs.

[0029] In a special configuration of the invention, the awning legs can each be housed inside one of the awning arms. It may be specified in particular that one awning leg can be pushed into one of the awning arms in its longitudinal direction. This allows the awning to be designed in a particularly space-saving manner, and thus the awning housing to be designed in a particularly compact and wind-resistant manner.

[0030] Preferably, the awning legs are each attached at one longitudinal end to a awning arm, in particular to the inner arm section, and are preferably configured to be telescopically retractable together with the inner arm section of the awning arm. This not only allows for compact, space-saving storage of the awning legs, but also allows for predefined, permanent allocation of each awning leg to the storage space provided for it. Furthermore, due to the awning legs being in close proximity to the awning arms, handling during assembly and disassembly of the awning is particularly easy.

[0031] Particularly preferably, the shade legs are pivotally attached to the shade arms, in particular at one longitudinal end of the shade arms, in particular at the inner arm section. The joint between the shade legs and the shade arms can be configured as a common pivot bearing, for example, with a fork bearing base arranged in particular in the end region of the shade arm, a joint head arranged in particular in the end region of the shade leg, and a joint pin that supports the joint head in the fork bearing base. This allows for particularly inexpensive production and particularly easy and simple handling of the shade legs when assembling and dismantling the shade.

[0032] Preferably, the shading arms and legs have substantially identical cross-sectional contours, which may be rectangular with rounded corners, for example. Additionally, at least one of the planar surfaces may be provided with curves, grooves, notches or other contours extending over the entire length of the respective component. This may improve the stability and guiding accuracy of the shading arms and legs, particularly in the longitudinal direction.

[0033] It will be clear that the above-described configuration of the awning legs, in particular the configuration that they can be stored in the awning arms, is of course also possible without a special configuration of the awning rollers and / or awning arms, in particular without the awning rollers and / or awning arms being suitably configured for pretensioning the awning fabric.Accordingly, an otherwise conventional awning may also be configured according to the invention so that the awning legs are respectively retractable and thus installable in the awning arms and / or pivotally attached to the awning arms in particular in the above-described manner.

[0034] In one particular embodiment of the invention, both longitudinal ends of the shade roller are rotatably mounted in end caps, in particular in sections of the strips, also referred to as front strips, configured as end caps. This allows the shade roller to be mounted particularly simply to the free ends of the shade arms, in particular with the end caps that are not rotatable. These end caps can thus act as non-rotatable supports, in particular attached to the shade arms, both during assembly and removal of the shade and during subsequent adjustment of an already assembled shade, while the shade roller can be freely rotatable, for example to unwind the shade cloth when extending the shade arms. This allows the shade to be handled particularly easily.

[0035] It has proven particularly advantageous if a front strip is additionally arranged between the two end caps along the longitudinal extension of the shade roller. The front strip (like the end caps) is arranged non-rotatably (also called "immobile") and, in particular, at a small distance from the shade roller. This allows the shade roller, which is supported on the shade arm via the end caps, to be particularly easily gripped by hand with the front strip and, in particular with a simultaneously freely rotatable shade roller, to be moved accordingly to the desired position without the user having to use both hands to move the shade roller.

[0036] In a particular embodiment of the invention, a pretensioning means, preferably a spring, preferably an axial spring, is arranged between the end cap and the shade roller in order to pretension the shade cloth and / or the shade roller, such that the spring gradually tightens when the shade cloth is unwound and gradually relaxes when the shade cloth is wound onto the shade roller. This allows the shade cloth to be tensioned at any time, in particular during assembly and removal of the shade as well as during re-adjustment. This allows for particularly easy handling of the shade.

[0037] Preferably, the spring is arranged in a cavity or inside the shade roller, in particular integrated into the shade roller, which allows for a particularly space-saving and compact design.

[0038] In one particular embodiment of the invention, the awning has a awning housing in which the awning roller, in particular with the front strip and end caps, the awning cloth and the awning arms can be stored. Furthermore, the awning legs can be stored inside the awning arms. In this way, the awning in the retracted state has a particularly compact and low-wind-resistance configuration, so that it forms only a small wind surface when the campervan is moving.

[0039] Preferably, the awning housing has a head cover at at least one longitudinal end, which head cover is formed as a push button that is pressed to open the awning housing, in particular the openable front cover of the awning housing. This allows for particularly easy handling for opening the awning, in particular the awning housing. The head cover is preferably integrated into the awning housing, and in particular may form an end wall of the awning housing. This allows the awning housing to be designed with particularly low wind resistance. The front cover, which may extend over the entire width of the awning or the awning housing, preferably opens outward. Opening the front cover allows access, in particular, to the interior of the awning housing. The awning housing therefore preferably includes at least one back wall by which the awning housing can be attached to a campervan, a bottom, an openable front cover, and two lateral head covers. Depending on the length configuration of the shading arms and / or shading legs, the shading arms and / or shading legs may be arranged laterally adjacent to each other in the shading housing or one after the other in the longitudinal direction thereof.

[0042] 1 shows a first embodiment of an awning according to the invention in an assembled state arranged on a camper, generally designated 100. In this state, it can be seen that the awning 100 comprises, in particular, an awning housing 8 attached to the camper, two awning arms 3, 3' extending from the awning housing 8 and awning legs 4, 4' respectively arranged on the awning arms, a awning roller 2 and a awning cloth 1 that can be rolled up on the awning roller 2.

[0043] In the assembled state of the awning, also referred to as the unfolded awning, shown in FIG. 1, the awning cloth 1 is at least partially unwound from the awning roller 2 and extends substantially over the base frame 11 formed by the awning arms 3, 3' and the awning legs 4, 4'. The awning rollers 2 are arranged in this case at the longitudinal ends 5, 5' of the awning arms 3, 3' facing away from the campervan and are in particular locked to the awning arms 3, 3'. To lock the awning rollers 2 to the awning arms 3, 3', coupling devices 12, 12' are provided, respectively, and can be seen in greater detail in FIGS. 6, 7 and 10. The awning arms 3, 3' and the awning legs 4, 4' are each formed in two parts in this embodiment and are configured to be telescopically extendable in length. Furthermore, in this embodiment, it is specified that the awning legs 4, 4' can be stored inside the awning arms 3, 3'.

[0044] The sunshade 100 is configured in this embodiment as a manually operable sunshade, and the assembly and disassembly of the sunshade is carried out exclusively manually or by hand, which in particular involves the base frame 11 and the positioning of the sunshade roller 2 and the associated unwinding or winding of the sunshade fabric 1.

[0045] The assembly of the awning 100 is described below in individual steps with reference to Figures 2 to 6 and 8 to 11. To avoid repetition, it is made clear that the configuration described with respect to one of the awning arms or one of the awning legs applies equally to the other and / or another awning arm or awning leg, respectively.

[0046] 2 shows the sunshade 100 in the closed position, also called the retracted position. The sunshade 100 shown is normally in this position when the campervan is in operation. To assemble the sunshade 100, first the sunshade housing 8 is opened by pushing both head covers 9, 9' located at the longitudinal ends 8a, 8b of the sunshade housing 8 towards the rest of the sunshade housing 8. The head covers 9, 9' are configured in this embodiment as so-called push buttons, which return to their starting position after being moved forward or pressed and thereby triggering, i.e., in this embodiment, releasing the closing device in particular.

[0047] In Figure 3, the awning housing 8 is shown in its open state. To open the awning housing 8, the housing cover 20 can be swung upwards by releasing a closing device (not shown in detail) when both head covers 9, 9' are pressed. The housing cover 20 extends over the upper side and the front side facing away from the campervan. Upper side or top here particularly means the side of the awning housing 8 facing away from the awning bottom 19. In the upper area of the interior of the awning housing 8, the awning roller 2 can be seen together with the awning cloth 1 rolled up on the awning roller 2, and in the lower area the awning arms 3, 3' can be seen. In this state, the awning cloth 1 and the awning roller 2 are not directly visible in Figure 3, as they are hidden by the front strip 13.

[0048] In a next step, as shown in Figure 4, it is envisaged that the first of the two shade arms 3, 3' is removed from the shade housing 8 by hand, in particular by pivoting the shade arm 3 by approximately 90° about the longitudinal end 8a of the shade housing 8. For this purpose, the shade arm 3 is pivotally supported in the shade housing 8, in particular via a joint 21 which is shown in more detail in Figure 8.

[0049] In a further step, as shown in detail from the drawing in Figure 8 to the drawing in Figure 9, first the shading leg 4 stored in the shading arm 3 is removed. The shading leg 4 can be pulled out from the interior of the shading arm 3 in the longitudinal extension direction of the shading arm 3, in this case in particular by means of the longitudinal ends of the shading leg 4 which are respectively provided as shading bases 18, 18'.

[0050] After the shade leg 4 has been fully pulled out from inside the shade arm 3, the shade leg 4 can be angled by a joint 23 located between the shade arm 3 and the shade leg 4, particularly at one longitudinal end 40 of the shade leg, as shown in detail from the drawing in Figure 9 to the drawing in Figure 10.

[0051] In order to adapt the height of the shade 100 in the region of the shade legs 4, 4' to the height of the respective foundation, the shade legs 4, 4' are designed to be length-adjustable, in particular telescopically extendable. In a next step, the length of the shade leg 4 is adapted by pulling the inner leg element 42 away from the outer leg element 41, as shown in detail in Figure 10. The leg elements 41, 42 may each form a section of the overall longitudinal extension of the shade leg 4, 4' and are therefore also referred to as leg sections 41, 42, in particular the outer or first leg section 41 and the inner or second leg section 42.

[0052] Locking the inner leg element 42 to the outer leg element 41 at the individually adjustable length of the awning legs 4, 4' can be achieved in a manner known per se, for example by means of a spring-loaded pin arranged on the inner leg element 42, which can engage in one of several notches arranged on the outer leg element 41. With such a configuration of the locking mechanism, both leg elements 41, 42 are blocked in both directions of movement in the longitudinal extension of the awning legs 4, 4'.

[0053] In a further step, the provisional or already desired final depth of the shade 100 can then first be individually adjusted. By depth is meant here in particular the dimension of the shade in the unwinding or winding direction of the shade cloth 1. For this purpose, as shown in detail in FIGS. 10 through 11, it is assumed that the inner arm element 32 is pulled out from the outer arm element 31, to one longitudinal end 3a of the inner arm element 32 a shade leg 4, 4', in particular the outer leg element 41, is attached. The arm elements 31, 32 may each form a section in the longitudinal extension of the entire shade arm 3, 3' and are therefore also referred to as arm sections 31, 32, in particular the outer or first arm section 31 and the inner or second arm section 32.

[0054] Both the shade arms 3 and the shade legs 4 have in this embodiment substantially identically formed cross-sectional profiles, so that the individual components fit together particularly precisely. In order to better stabilize and guide the individual elements of the shade arms 3 and the shade legs 4 relative to one another, in this embodiment, a correspondingly arranged guide groove 43 is provided between the inner leg element 42 and the outer leg element 41 in the upper, flatly formed surface of the cross-sectional profile in the example of the shade leg 4, as can be seen in particular in Figure 8.

[0055] In order to lock the retractable inner arm element 32 to the outer arm element 31 in the desired position, in particular to block telescopic accessibility, in this embodiment a locking system 6 is provided, as shown in detail in Figures 12 to 14.

[0056] In this embodiment, the locking system 6 is configured in particular to block telescopic accessibility of the second arm element 32 relative to the first arm element 31 in only one of both possible directions of movement R1, R2 in the longitudinal extension direction, in particular to block pushing of the inner arm element 32 into the outer arm element 31, which is shown in the drawings as direction R1. For this purpose, the locking system 6 is arranged substantially between the outer arm element 31 and the inner arm element 32, in particular in the region of the longitudinal end 24 of the outer arm element 31, in particular on the outer surface 35 of the inner arm section 32.

[0057] As can be seen in particular in Figure 13, the locking system 6 is configured in this embodiment as a locking device 7. The locking device 7 comprises a rack 61 arranged on the inner arm element 32 with a number of helical teeth 62, each of which has a locking surface 63 facing the outer arm element 31. As a counter part, the locking device 7 comprises a locking tongue 64, also called a locking lever, arranged on the outer arm section 31 and with a locking protrusion 66. The locking protrusion 66 can slide freely on the flat angled surface of the helical teeth 62 when the inner arm element 32 is pulled out in the direction R2. On the other hand, when the inner arm element 32 is pushed into the outer arm section 31 in the direction R1, the locking protrusion 66, due to the preload acting on it by the locking tongue 64, abuts against the locking surface 63 of one of the helical teeth 62 with the locking side surface 67 formed on the locking protrusion 66, and thus engages with this locking surface 63, thereby blocking further movement of the inner arm element 32 in this direction R1.

[0058] To release the locking connection 7, in particular to separate the locking flank 67 from the locking surface 63, a slidable actuating member 65 is provided in this embodiment. The actuating member 65 is operatively connected to the locking tongue 64 via a wedge-shaped connection 68, so that when the actuating member 65 is slid in the direction of the locking tongue 64, the locking tongue 64 is pressed away from the rack 61, thereby allowing the locking flank 67 to be disengaged from the locking surface 63. For this purpose, the actuating member 65 is configured as a flat, slidable member with a front section 65a and a rear section 65b.

[0059] The front section 65a is disposed between the locking tongue 64 and the rack 61, and is in contact with the rack 61, particularly with its lower flat surface, and with the locking tongue 64 with the end surface of the wedge-shaped connecting portion 68. This allows the locking tongue 64 to be lifted, particularly in the direction away from the rack 61, and thus the locking side surfaces 67 to be separated, when the operating member 65 is slid forward in the direction of the wedge-shaped connecting portion 68.

[0060] The rear section 65b of the actuating member 65 is arranged in particular on the outer contour of the outer arm element 31 and is shaped in such a way that it is suitable for manipulation, in particular for sliding by hand. In particular, the rear section 65b may have a surface and / or contour that is ergonomic for the fingers, in particular the thumb.

[0061] The entire locking system 6, in particular the rack 61, the locking tongue 64 and the actuating member 65, can be configured in such a way that the locking system 6 is arranged completely inside the projected outer periphery contour U of the shading arm 3, 3'. In the configuration shown in the drawings, only the locking tongue 64 and the actuating member 65 of the locking system 6 protrude beyond the outer periphery contour U of the shading arm 3, 3'. It will be clear that with appropriate adaptation, in particular if the locking tongue 64 and the actuating member 65 are integrated, the entire locking system 6 can be arranged particularly advantageously inside the projected outer periphery contour U of the shading arm 3, 3'.

[0062] In a further step for assembling the awning 100, the individual steps described above with reference to Figure 4 are similarly carried out for the second awning arm 3' and the second awning leg 4', as shown in Figure 5. It should again be pointed out that the awning arms 3, 3' and the awning legs 4, 4' are each identically constructed.

[0063] In a further step, as shown in particular in Figure 6, the shade roller 2 is manually removed from the shade housing 8 and the shade cloth 1 is unwound from the shade roller 8. Unwounding occurs essentially automatically when the shade roller 2 is manually moved out of the shade housing 8 in the direction of the longitudinal ends 5, 5' of the shade arms 3, 3'. In this case, as shown in detail in Figure 7, both longitudinal ends 2a, 2b of the shade roller 2 are rotatably mounted in sections 14, 14' of the front strip 13, which are configured as end caps. This means that the front strip 13 and the end caps 14, 14' are arranged non-rotatably relative to the shade roller 2. This allows the front strip 13 to be used as a gripping element for the operator, in particular when moving the shade roller 2, making this work step particularly simple and easy to perform.

[0064] In this state, no special handling by the operator is required when assembling or dismantling the awning, since the base frame 11 is already assembled, especially when moving the awning roller 2 or unwinding the awning cloth 1. In particular, there is no need to support the awning arms 3, 3', since they are already supported by the awning legs 4, 4'.

[0065] It will be clear that in this embodiment the end caps 14, 14' comprise part of the connecting device 12, 12' and in particular have on their outer contours devices suitable for connecting or locking the respective end caps 14, 14' to the longitudinal ends 5, 5' of the sunshade arms 3, 3', in particular notches 44 suitable for the bayonet pins 33 arranged on the sunshade arms.

[0066] In order to pretension the sunshade cloth 1 and / or the sunshade roller 2, in this embodiment, as shown in particular in Figure 7, pretensioning means 10 are arranged between the end caps 14, 14' and the sunshade roller 2, respectively. In this embodiment, the pretensioning means 10 is formed as an axial spring 17, which is preferably connected at one end to the end cap 14 so as not to be rotatable relative to the sunshade roller 2 and at the other end to the sunshade roller 2 so as not to be rotatable relative to the sunshade cloth 1. In particular, the spring 17 is arranged inside the sunshade roller 2. As a result, the spring 17 gradually becomes tense when the sunshade cloth 1 is unwound, and gradually becomes relaxed when the sunshade cloth 1 is wound onto the sunshade roller 2. Therefore, when the sunshade roller 2 is manually moved from the sunshade housing 8 to the longitudinal ends 5, 5' of the sunshade arms 3, 3', the spring 17 gradually becomes tensioned, thereby automatically tensioning the sunshade cloth 1 present on the base frame 11.

[0067] As shown in Figure 6, after the shading roller 2 has been locked to the longitudinal ends 5, 5' of the shading arms 3, 3' by means of the coupling devices 12, 12', the shading cloth 1 can be additionally pretensioned by pulling the inner arm element 32 slightly further out of the outer arm element 31. This can be done particularly simply due to the special design of the locking system 6, in particular by the automatic locking of the locking tongue 64 on one of the helical teeth 62.

[0068] 15 and 16 each show an alternative configuration of an awning according to the invention, designated by the reference numeral 200. The awning 200 substantially corresponds to the awning 100 described above, with the only difference being that in the variant shown here the awning arms 3, 3' and / or the awning legs 4, 4' are arranged laterally next to each other in the longitudinal extension direction within the awning housing 8, rather than one behind the other in the longitudinal extension direction, as is for example assumed in the awning 100 shown in FIG. 3. This configuration can be advantageous in particular if the awning has a relatively small width B (here, width B means in the direction of the longitudinal extension of the awning housing 8) or, alternatively, if the awning arms 3, 3' and / or the awning legs 4, 4' are particularly long.

[0069] It will be clear that the scope of protection of the invention is not limited to the described embodiments. In particular, the assembly of the sunshade is entirely possible to modify without changing the essence of the invention. For example, the configuration and arrangement of the sunshade arms and sunshade legs may be different, in particular with regard to their arrangement in the sunshade housing and the respective cross-sectional contour.
