CROSS REFERENCE TO RELATED APPLICATIONS
[0001] The application is a divsional of Australian Application No. 2019203640, filed on 24 May 2019, which claims priority to German Provisional Patent Application No. 102018208370.3, filed 28 May 2018, the disclosure of which is incorporated herein by reference in its entirety and for all purposes. FIELD OF THE INVENTION
[0002] The present invention relates to an awning assembly for a vehicle, especially for a recreation vehicle, e.g. a camper, a caravan or a mobile home. Said awning assemblies are used to shelter an area next to the recreational vehicle from direct sunlight or from rain. BACKGROUND
[0003] Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.
[0004] In general, such awning assemblies comprise a main body which is fixable to a support structure of the recreational vehicle, e.g. a side wall. A roller tube is rotatably supported at the back cover so that a flexible awning material can be selectively rolled onto or from the roller tube. To achieve this effect, a lead rail is provided which is connected to a first end of the flexible awning material, wherein the second end of the flexible awning material is connected to the roller tube. Thus, by moving the lead rail away from the main body the flexible awning material is rolled off from the roller tube.
[0005] For supporting the lead rail, such awning assemblies generally comprise at least one tension rafter and at least one support leg. In general, the tension rafter is mountable between the main body and the lead rail when the flexible awning material is rolled off from the roller tube. In addition, the at least one support leg is also attached to the lead rail in a substantially perpendicular direction to support the lead rail on the ground surface when the awning assembly is in an operating state. To facilitate the handling, the lead rail often comprises lead rail frame, wherein the support leg is hinged to the lead rail so that the support leg can be hingewise moved into a first storage section of the lead rail frame in which 2024267067 10 Jun 2026 the longitudinal axis of the support leg is substantially parallel to the longitudinal axis of the lead rail. Thus, when assembling and disassembling the awning assembly, there is no need to remove the at least one support leg from the lead rail, which facilitates the handling of the awning assembly.
[0006] The tension rafter can have different forms and may e.g. be provided in form of arm assemblies having two parts being hinged together. Such an arrangement is shown in EP 1 767 722 A2. However, such complex arm assemblies distinctly increase the dimensions of the awning assembly and the costs thereof.
[0007] Thus, there are also solutions known comprising a tension rafter which is simply manually mounted between the lead rail and main body. To account for different distances between the main body and the lead rail and also to have a certain tension between the main body and the lead rail, said tension rafters are mostly telescopic tension rafters. Said tension rafters are easy to handle and are generally stored within the recreational vehicle when the awning assembly is not in use.
[0008] However, this bears the risk that the tension rafter gets lost or is forgotten somewhere, so that the awning assembly may not be used correctly when the recreational vehicle is parked. In addition, the available space within the recreational vehicle is often limited so that it is generally desirable to reduce the number of items which are to be stored or secured within the recreation vehicle. SUMMARY
[0009] It is an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.
[0010] It is and object of the present invention in at least one preferred form, to provide an awning assembly which allows for a secure storage of the tension rafter when not in use.
[0011] According to one aspect of the present invention, there is provided an awning assembly for a vehicle, especially a recreational vehicle, comprising a main body, a flexible awning material, a roller tube, a lead rail, at least one support leg hinged to the lead rail, and at least one tension rafter being mountable between the main body and the lead rail, wherein the roller tube is rotatably supported at the main body, and a first end of the flexible awning material is attached to the roller tube and a second end of the flexible 2024267067 10 Jun 2026 awning material is attached to the lead rail so that moving the lead rail relative to the main body selectively rolls the flexible awning material onto or from the roller tube, wherein the lead rail comprises a lead rail frame, wherein the at least one support leg is hinged to the lead rail so that the support leg can be hingewise moved into a first storage section of the lead rail frame in which the longitudinal axis of the support leg is substantially parallel to the longitudinal axis of the lead rail, wherein the lead rail frame comprises a second storage section for receiving the tension rafter therein, wherein the second storage section comprises an opening, wherein the tension rafter is self-clamping into the second storage section.
[0012] According to another aspect of the present invention, there is provided an awning assembly for a recreational vehicle, comprising: a main body, a flexible awning material, a roller tube, a lead rail, at least one support leg hinged to the lead rail, and at least one tension rafter being mountable between the main body and the lead rail, wherein the roller tube is rotatably supported at the main body, and a first end of the flexible awning material is attached to the roller tube and a second end of the flexible awning material is attached to the lead rail so that moving the lead rail relative to the main body selectively rolls the flexible awning material onto or from the roller tube, wherein the lead rail comprises a lead rail frame, wherein the at least one support leg has a first hinged connection to a carriage and the carriage has a second hinged connection to the lead rail so that the at least one support leg can be hingewise moved into a rearward first storage section of the lead rail frame in which a longitudinal axis of the at least one support leg is substantially parallel to a longitudinal axis of the lead rail, said first hinged connection having a first pivot axis and said second hinged connection having a second pivot axis perpendicular to said first pivot axis; wherein said carriage is slidably positionable in said rearward first storage section, and said at least one support leg is configured to be stored in said rearward first storage section; wherein the lead rail frame comprises a forward second storage section configured to store the at least one tension rafter therein, said forward second storage section positioned closer to a leading edge of the lead rail than the rearward second storage, such that the forward second storage section is positioned further from said roller tube than said rearward first storage section when the awning assembly is in an extended position; and wherein the carriage is slidably movable along the longitudinal axis of the lead rail between a first position adjacent to a first axial end of the lead rail frame and a second position in an area between a middle of the lead rail frame and a second axial end of the lead rail frame, wherein the at least one support leg 2024267067 10 Jun 2026 is movable into the first storage section when the carriage is in the second position, such that a bottom of the at least one support leg is positioned adjacent to the first axial end of the lead rail frame when the at least one support leg is stored in said rearward first storage section.
[0013] According to another aspect of the present invention, there is provided an awning assembly, comprising: an awning material which is connected at one end to a roller tube and at a second end to a lead rail, wherein the awning material is capable of being selectively rolled onto said roller tube or being selectively extended by movement of the lead rail relative to the awning roller tube; said lead rail having a lead rail frame and a rearward storage section which extends longitudinally defining a longitudinal direction; one or more support legs slidably and hingedly movable relative to the lead rail frame and wherein said one or more support legs can be pivoted into a support position that is perpendicular to the lead rail to support said lead rail; a carriage having a first hinged connection to one of said one or more support legs, wherein said first hinged connection has a first pivot axis and a second hinged connection to the lead rail has a second pivot axis perpendicular to said first pivot axis, wherein said one or more support legs can be hingedly moved into said rearward storage section of said lead rail frame in which a longitudinal axis of each of said one or more support legs is substantially parallel to said longitudinal direction of the lead rail such that a bottom of the one or more support legs is positioned adjacent to a first axial end of the lead rail frame when the one or more support legs is stored in said rearward storage section; said carriage being slidable within said rearward storage section, wherein in one position of said carriage, said one or more support legs may be pivoted into said support position, and wherein in a second position said one or more support legs may be pivoted into said rearward storage section; said lead rail having a forward storage section configured to store each of one or more tension rafters, wherein said forward storage section is further from said awning material than said rearward storage section.
[0014] One aspect of the present invention provides an awning assembly for a vehicle, especially a recreational vehicle, comprising a main body, a flexible awning material, a roller tube, a lead rail, at least one support leg hinged to the lead rail, and at least one tension rafter being mountable between the main body and the lead rail.
[0015] According to the invention, the roller tube is rotatably supported at the main body, and a first end of the flexible awning material is attached to the roller tube and a second end of the flexible awning material is attached to the lead rail so that moving the lead rail relative to the main body selectively rolls the flexible awning material onto or from the roller tube. 2024267067 10 Jun 2026
[0016] According to the invention, the lead rail comprises a lead rail frame, wherein the at least one support leg is hinged to the lead rail so that the support leg can be hingewise moved into a first storage section of the lead rail frame in which the longitudinal axis of the support leg is substantially parallel to the longitudinal axis of the lead rail.
[0017] According to the invention, the lead rail frame comprises a second storage section for receiving the tension rafter therein, while the second storage section comprises an opening, wherein either a holding means is disposed within the opening, or the tension rafter is self-clamping into the second storage section.
[0018] Thus, not only the support leg is stored in a specific storage section of the lead guide rail, but also the tension rafter is manually stored in the second storage section, which is included in the lead rail frame and, hence, not within the recreational vehicle. As such, the tension rafter shall not be stored within e.g. the recreational vehicle when the awning assembly is not in use. This greatly reduces the risk of the tension rafter to get lost and thus to corrupt the correct functionality of the awning assembly. In addition, this also facilitates room use within the recreational vehicle.
[0019] Preferably, the second storage section is an integral member of the lead rail frame. This allows for a compact design. In addition, manufacturing is greatly facilitated as the entire lead rail frame including the second storage section can be provided e.g. by continuous profile casting. In particular, the lead rail frame can be made of an aluminium alloy or a plastic material.
[0020] Preferably, regarding the self-clamping alternative of the tension rafter, the tension rafter has an elongated form and is capable of clamping itself into the second storage section in a force-locking manner by exerting a force in the longitudinal direction of the tension rafter. Thereby, no extra holding means are necessary at the second storage section and the embodiment provide for a very smooth and easy handling.
[0021] Preferably, the force is exerted by a spring comprised by the tension rafter, which pushes an abutment element of the tension rafter in the longitudinal direction of the tension rafter and the abutment element abuts against an end portion of the second storage section, when the tension rafter is stored therein. This is a preferred way to create the force-locking. 2024267067 10 Jun 2026
[0022] Preferably, the tension rafter comprises the spring and the abutment element at each of its axial ends. This even increases the flexibility of the handling and, if once one of the mechanisms will not work anymore, the clamping still works because of the second one.
[0023] Preferably, at least one end portion of the second storage section is represented by a tension rafter holder, designed as a counterpart to the abutment element which is variable in its position so that the length of the second storage section can be varied. This counterpart can also be defined as a tension rafter holder. An advantage of this embodiment is that, once the springs decrease in strength, the space provided by the second storage section can be downsized in order to get more force on the force-locking clamping again. Furthermore, various tension rafters different in length can be stored.
[0024] Preferably, tension rafter holder additionally provides for clamping the tension rafter into the second storage section in a form-locking manner. The form-locking provides further stability of the stored tension rafter in addition to the force-locking manner of the selfclamping.
[0025] Preferably, the lead rail frame comprises a first receiving portion and the main body comprises a second receiving portion, wherein the first and second receiving portions are configured to each receive an axial end of the tension rafter. When the awning assembly is in use, the tension rafter can thus easily be installed to the main body and to the lead rail frame so that tension is exerted on the flexible awning material.
[0026] Preferably, the lead rail comprises a carriage being mounted to the lead rail frame so as to be slidably movable along the longitudinal axis of the lead rail, wherein the at least one support leg is hingewise mounted to the carriage. Thus, the position of the support leg can be adjusted in its lateral position relative to the lead rail.
[0027] Preferably, the carriage is slidably movable between a first position in the area of the first axial end of the lead rail frame and a second position in the area between the middle of the lead rail frame and the second axial end of the lead rail frame, wherein the at least one support leg is movable into the first storage section for every position of the carriage between the first position and the second position. Hence, this greatly reduced the lateral space requirements for moving the support leg from or to the first support portion. That is because the carriage can e.g. be slid into about the middle of the lead rail frame before the support leg is tilted into the first support portion. In addition, the awning assembly canthus be 2024267067 10 Jun 2026 operated much easier, as the support leg can be moved along the lead rail frame even when being in the operating state, i.e. substantially perpendicular to the longitudinal axis of the lead rail.
[0028] Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise”, “comprising”, and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to”.

[0041] In Fig. 1 and Fig. 2 there is shown an inventive awning assembly 1 in the operational state. The awning assembly 1 comprises a main body 2 attached to a (not shown) support structure of a (not shown) recreational vehicle in a known manner. The main body 2 comprises a roller tube 4 which is rotatably supported at the main body 2. The awning assembly 1 further comprises a lead rail 5 and a flexible awning material 3. A first end of the flexible awning material 3 is attached to the roller tube 4 and a second end of the flexible awning material 3 is attached to the lead rail 5. Moving the lead rail 5 relative to the main body 2 thus rolls the flexible awning material 3 onto the roller tube 4 or from the roller tube 4 in a known manner.
[0042] The lead rail 5 comprises a lead rail frame 8 and two support legs 6 which are hingewise mounted to the lead rail frame 8 via a carriage 18. The support legs 6 can be pivoted relative to the carriage 18 so that they are moved to or from a first storage section 9 of the lead rail frame 8, as will be explained in further detail below in reference to Figs. 6 and 7.
[0043] The awning assembly 1 further comprises a tension rafter 7. As shown in Fig. 1, the tension rafter 7 is an elongated tubular member which comprises of two parts 7a, 7b which are telescopically mounted to each other. Thus, the tension rafter 7 can be adjusted in its axial extension in that the first part 7a is slidably extended from the second part 7b and the fixed against further movement in known manner, e.g. by rotating the first part 7a relative to the second part 7b. As can be further seen from Fig. 1, the axial end of the first part 7a of the tension rafter 7 is mounted to a first receiving section 16 of the lead rail frame 8, wherein the axial end of the second part 7b of the tension rafter 7 is mounted to the a second receiving section 17 of the main body 2. Thus, the tension rafter 7 exerts tension onto the flexible awning material 3 and further supports the lead rail 5 in its position in combination with the support legs 6.
[0044] When the awning assembly 1 is in the non- usage state, the support legs 6 are located in the first storage section 9 (cf. e.g. Fig. 6) and the flexible awning material 3 is nearly completely rolled onto the roller tube 4. The tension rafter 7 is also demounted from the first and second receiving sections 16, 17 and the first part 7a is about completely disposed within the second part 7b. For storing the tension rafter 7, the lead rail frame 8 comprises a second storage section 10, which is integrally formed with the lead rail frame 8. 2024267067 10 Jun 2026 In particular, the lead rail frame 8 of the present invention is made from continuous profile casting of e.g. an aluminum alloy.
[0045] As shown in Figs. 3 and 4, the second storage section 10 comprises an opening 11 for introducing the tension rafter 7 into the second storage section 10. In addition, there is provided a holding means 12 which is disposed within the opening 11 or in the area of the opening 11. The holding means 12 is composed of a bent spring wire and comprises a bracket 13 which can be manually moved between a holding position (as shown in Fig. 3) to a releasing position, the latter one being indicated by the bold arrow in Fig. 3. As the bracket 13 is also of flexible material, it returns into its original holding position when let loose. As a matter of course, the holding means 12 can be composed of any suitable material having flexibility.
[0046] In addition, the holding means 12 comprises a hooking projection 14 which hooks into an abutment projection 15 of the lead rail frame 8. As shown in Fig. 3 and Fig. 4 the abutment projection 15 is integrally formed with the lead rail frame 8 and extends into the second storage section 10. When the hooking projection 14 is hocked into the abutment projection 15, the holding means 12 is hindered from moving rotationally within the second storage section 10 when the bracket 13 is moved manually into the releasing position.
[0047] For introducing the tension rafter 7 into the second storage position 10 the bracket 13 is manually moved into the releasing position and the tension rafter 7 is inserted through the opening 11 into the second storage section 10. When the tension rafter 7 is completely disposed within the second storage section 10 the bracket 13 is unhanded and thus returns into the holding position. In said holding position the tension rafter 7 is form- locked fixed in the second storage section 10, as shown in Fig. 4.
[0048] To remove the tension rafter 7 again, the bracket 13 is manually moved into the releasing position and the form- lock fixing between the tension rafter 7 and the holding means 12 is suspended. Then, the tension rafter 7 can be removed from the second storage section 10 via the opening 11. After the tension rafter 7 is removed, the bracket 13 is again unhanded and it returns into its original holding position.
[0049] As shown in Fig. 2, the awning assembly comprises two support legs 6 each being mounted to the lead rail frame 8 via a carriage 18. The carriage 18 is slidably mounted to the lead rail frame 8 so as so be slidably movable along the longitudinal axis LR of the lead rail 5. 2024267067 10 Jun 2026 In particular, each of the carriages 18 is movable between an axial end 19, 20 of the lead rail frame 8 and about the middle 21 of the lead rail frame 8.
[0050] As such, the carriage 18 the right support leg 6 shown in Fig. 2 is attached to is movable between a first position in the area of first axial end 19 of the lead rail frame 8 and a second position in the area between the second axial end 20 of the lead rail frame 8 and about the middle 21 of the lead rail frame 8. Hence, the carriage 18 of the left support leg 6 shown in Fig. 2 is attached to is movable between a first position in the area of second axial end 20 of the lead rail frame 8 and a second position in the area between the first axial end 19 of the lead rail frame 8 and about the middle 21 of the lead rail frame 8.
[0051] As shown in Fig. 6 and Fig. 7 for moving the support leg 6 into the first storage section 9, the carriage 18 is slidably moved from the first position in the area of the first axial end 19 of the lead rail frame 8 into the second position which is about in the middle 21 of the lead rail frame 8. As the support leg 6 is hingewise mounted to the carriage, it can thus be pivoted or tilted so that the longitudinal axis LS of the support leg 6 is substantially parallel to the longitudinal axis LR of the lead rail 5. When assembling the awning assembly 1 into the operating state, the support leg 6 is first pivoted from the first storage position 9 into an operating position, i.e. a position where the support leg 6 is substantially perpendicular to the lead rail 5. Second, the carriage 18 is slidably moved from the second position in the area of the middle 21 of the lead rail frame 8 to the first position in the area of the first axial end 19 of the lead rail frame. An identical course of action is carried out for the other support leg 6. This also allows for facilitated handling, as the support legs 6 do not need to be tilted from a fixed position in the area of the axial ends 19, 20 of the lead rail 5.
[0052] In Fig. 8 the self-clamping alternative is illustrated with an exemplary embodiment. As can be seen, the tension rafter 7 is already place within the space of the second storage section 10. In the shown situation, the abutment element 23 is still pushed away from the tension rafter holder 24 being designed as the counterpart to the abutment element 23. Now, when the abutment element is loosened somehow, it will be pushed by the spring inside the tension rafter 7 in the direction of the tension rafter holder 24 the result of which can be seen in Fig. 9. As shown therein, the tension rafter 7 is self-clamped into the second storage section 10 in a force-locking and form-locking manner. The holder 24 is formed such that it fits to the form of the abutment element 23, thereby forming the counterpart of the abutment element 23 at the contact portion of the two components. In order to take the tension rafter 7 2024267067 10 Jun 2026 out again, the abutment element 23 simply must be pushed back to disengage with the holder 24 again.
[0053] As can be seen in Fig. 10, the force with which the abutment element 23 is pressed against the tension rafter holder 24 can be exerted by a spring 22 according to one embodiment of the invention. In a preferred embodiment, the spring 22 is a coil spring which is wound around a piston having the abutment element 23 at its end corresponding to the axial end of the tension rafter 7. This embodiment of the tension rafter 7 is shown in the cross-sectional view of Fig. 11 in which three situations A, B and C are shown. As can be easily grasped from Fig. 11, Situation A represents a middle position of the abutment element 23, while situations B and C represent the two end positions, B the retracted and C the extended position. 2024267067 10 Jun 2026 OF REFERNECE SIGNS awning assembly main body flexible awning material roller tube lead rail support leg tension rafter first part of tension rafter second part of tension rafter lead rail frame first storage section second storage section opening holding means bracket hooking projection abutment protrusion first receiving portion second receiving portion carriage first axial end of lead rail frame second axial end of lead rail frame middle of lead rail frame spring abutment element tension rafter holder middle position of self-clamping tension rafter retracted position of self-clamping tension rafter extended position of self-clamping tension rafter longitudinal axis of support leg longitudinal axis of lead rail
