[0015] Another objective of the invention is to provide a roof rack device which offers the possibility of extending the living space outside the vehicle.

[0016] This problem is solved by a roof rack device having the features of independent claim 1. Advantageous embodiments of the invention are specified in the dependent claims. The following terms will be explained:

[0017] The term "vehicle" can refer to any type of vehicle. In this context, "vehicle" specifically refers to a road vehicle. More specifically, it refers to a motor vehicle such as a van or a pickup truck. A pickup truck, in this context, is specifically understood to be a car, truck, or off-road vehicle with an open cargo bed.

[0018] A roof rack is a device that can be attached to the roof or body of a vehicle. Cargo can be secured to the roof rack.

[0019] The base support element of the roof rack system serves, on the one hand, to attach the roof rack system to the roof or the vehicle body. On the other hand, the base support element includes the extension support element, which is pivotably mounted relative to the base support element.

[0020] When used as intended, the extension support element is arranged in a first position above the base support element, in particular parallel to it, and in a second position pivoted upwards relative to the base support element.

[0021] The extension element is slidably arranged relative to the extension support element. In its intended use, the extension element is, in a first position, arranged within or on the extension support element, and in a second position, it is pulled out on one side of the extension support element, so that one surface of the extension element increases the surface area of ​​the extension support element.

[0022] The extension element can preferably be pulled out of the extension carrier element perpendicular or parallel to the direction of travel. According to a preferred embodiment, the extension element can also be pulled out of the extension carrier element in another direction.

[0023] The roof rack device is in a transport position if the extension support element is arranged in the first position, preferably parallel to the base support element, and the extension element is in the first position, i.e., arranged in or on the extension support element.

[0024] The roof rack device is in a lifting position if the extension support element is in the second position, i.e. pivoted to the base support element, and the extension element is in the first position, i.e., located in or on the extension support element.

[0025] The roof rack device is in a loading position if the extension carrier element is in the second position, i.e. pivoted to the base carrier element, and the extension element is in the second position, i.e., pulled out from the extension carrier element.

[0026] The roof rack is in a usage position when the extension support element is arranged in the first position, preferably parallel to the base support element, and the extension element is in the second position, i.e., extended from the extension support element. In this usage position, the roof rack can be used for living or camping.

[0027] The base support element has a pivoting device which is designed and configured to pivot the extension support element from the first to the second setting and from the second to the first setting.

[0028] The extension support element has a sliding device which is designed and configured to move the extension element from the first to the second setting and from the second to the first setting.

[0029] The pivoting device has a first adjustment mechanism, and the sliding device has a second adjustment mechanism. The first adjustment mechanism is designed and configured to set the pivoting device in a position between the first and second settings, and the second adjustment mechanism is designed and configured to set the sliding device in a position between the first and second settings.

[0030] One side of the pull-out element can be used for sitting or camping. Furthermore, one side of the pull-out element, together with the pull-out support element, can be used for sitting or camping.

[0031] Preferably, the first adjustment device and the second adjustment device are designed and configured in such a way that a user can operate the first adjustment device or the second adjustment device largely without force.

[0032] In the event that the first adjustment device or the second adjustment device is operated by means of a crank, the operation is completely force-free apart from the rotational force of the crank.

[0033] The roof rack according to the invention can advantageously be operated with minimal effort, particularly with one hand. Since both the first and second adjustment mechanisms can be adjusted between their respective settings with minimal effort, the roof rack device does not require any support or holding from the user at any point during operation after installation on the roof. From a safety perspective, this represents a significant increase in the safety of operating the roof rack device.

[0034] The roof rack device advantageously allows a user standing on the ground next to the vehicle to easily load the roof rack device with cargo and stow it securely on the roof of the vehicle.

[0035] Another advantage of the roof rack device according to the invention is that the usable area on the roof of the vehicle, in particular for staying or camping, is increased, especially laterally.

[0036] Another advantage of the roof rack device according to the invention is that the roof rack device can be used both above and below the roof of the vehicle, thus offering multifunctional use.

[0037] Another advantage of the roof rack device according to the invention is that it offers the user, particularly in camping situations, protection from sunshine, wind, precipitation, especially rain and hail, as well as protection from unwanted persons or wild animals, and provides security as a refuge or sleeping place. In the case of hail, the roof rack device protects the user from injury and prevents hail damage to the vehicle.

[0038] Furthermore, the living space can be extended outside the vehicle using the roof rack system.

[0039] According to a preferred embodiment, the pivoting device comprises a lifting element, in particular an elongated one, and the first adjusting device comprises a threaded rod. The threaded rod is arranged perpendicular to a pivoting axis, in particular parallel to the roof of the vehicle.

[0040] Furthermore, one end of the lifting element having a nut is articulated to the threaded rod via the nut, and one end of the lifting element opposite the nut is articulated to a predetermined point on the extension support element, so that a rotational movement of the threaded rod moves the end of the lifting element having the nut perpendicular to the direction of travel, thereby causing the extension support element to be raised or lowered.

[0041] The rotary movement of the threaded rod, i.e. the drive rod, can preferably be effected manually, by an electric motor or by a cordless screwdriver.

[0042] This mechanism of the swivel device advantageously achieves the ability to raise or lower the extension support element by means of a simple rotary movement of the threaded rod.

[0043] Alternatively or in addition to the aforementioned pivoting mechanism, other forms of drive mechanism are possible, as listed below. A threaded axle with a spindle and spindle nut can be used. Furthermore, a drive axle with a gear and worm gear is another alternative. Yet another alternative is a gear on a rack and pinion track. Other alternatives may employ different gear mechanisms.

[0044] Suitable drives include rotary movements in linear motion, i.e., spindle-nut systems, or rotating movements, i.e., worm gears.

[0045] There are therefore two fully automated aids available at the push of a button: a threaded axis with direct drive for spindle and spindle nut gearbox and / or a drive axis with direct drive for worm gear.

[0046] According to yet another preferred embodiment, the displacement direction includes a rail element in which the extension element is guided. This advantageously ensures that the extension element can be easily moved within the rail element from the first position to the second position and from the second position to the first position.

[0047] According to yet another preferred embodiment, the second adjusting device has a second threaded rod which runs parallel to the rail element and is mounted between two receptacles in the extension element. Here, the second threaded rod passes through a second nut which is arranged on the extension support element in or on a pivot joint for pivoting the extension support element relative to the base support element. Furthermore, a rotational movement of the second threaded rod causes the second threaded rod to shift relative to the second nut, so that the extension element is shifted within the rail element relative to the extension support element.

[0048] This advantageously allows the extension element to be easily moved between the first and second settings using the simple-to-operate second adjustment mechanism. This increases both the user-friendliness and the safety of operating the roof rack system.

[0049] According to a further preferred embodiment, in a position where the pivoting device is pivoted and the extension element is extended, a support element can be arranged between the floor on which the vehicle is mounted and the extension element, so that the space between the floor and the extension element can be used for standing. This advantageously allows the space between the floor and the stable and robust extension element to be used as a secure roof. A further advantage is that the upper surface of the extension element, together with the extension support element, can also be used for standing, particularly for camping. For this purpose, it is preferred to attach a railing to the edge of the extension element and / or the extension support element.

[0050] According to a preferred embodiment, a transport item can be reversibly and detachably attached to or in the extension element. This advantageously allows the transport item to be fixed to the roof rack during transport and, after transport, to be easily detached and removed from the roof rack.

[0051] According to a further preferred embodiment, the total surface area of ​​the extension support element and the extension element in the extended state is at least twice as large as the surface area of ​​the extension support element. This advantageously allows the entire area to be used as a terrace or enlarged level.

[0052] According to yet another preferred embodiment, the weight of the roof rack device is less than 100 kg. This advantageously ensures that the permissible roof load capacity of the vehicle is not exceeded.

[0053] According to another preferred embodiment, the extension support element and / or the extension element has / have at least one fastening device. This advantageously ensures that the transported goods can be fixed to the roof rack, in particular to the extension support element and / or the extension element.

[0054] According to yet another preferred embodiment, the extension support element and / or the extension element has a receiving element for a ladder. This advantageously ensures that the roof of the vehicle can be easily accessed using the ladder.

[0055] According to a further preferred embodiment, the roof rack device also has at least one side wall which can be arranged between an outer wall of the vehicle and the support element. This advantageously extends the interior space of the vehicle by an additional, definable outer space.

[0056] Preferably, the roof rack device also includes a fastening device for attaching the roof rack device to the vehicle. This advantageously ensures that the roof rack is mounted and fixed to the vehicle roof.

[0057] According to a further preferred embodiment, in which the vehicle is a pickup truck, the roof rack device further comprises: an additional support for attaching the roof rack device to a loading platform of the pickup truck, to a side wall of the loading platform of the pickup truck, or to a frame of the loading platform of the pickup truck. Since the loading platform is generally located at the rear of the vehicle, the additional support is preferably also located at the rear.

[0058] This advantageously allows the roof rack to be mounted on a pickup truck with a cargo bed that is offset relative to the roof. In this case, the roof rack is attached at the front to the pickup truck's roof and at the rear, using the additional support, to the cargo bed, a side wall of the cargo bed, or a frame of the cargo bed. This advantageously increases the original cargo area of ​​the pickup truck by adding the loading or usable area of ​​the roof rack.

[0059] An embodiment of the invention is shown in the drawings and is explained in more detail in the following description.

Fig. Figure 7 shows the vehicle with a roof rack device according to an embodiment of the invention, wherein the vehicle is shown in a top view and the roof rack device is in a transport position. Fig. Figure 8 shows the vehicle with a roof rack device according to an embodiment of the invention, wherein the vehicle is shown in a top view and the roof rack device is in a usage position. Fig. Figure 9 shows the vehicle with a roof rack device according to an embodiment of the invention, wherein the vehicle is a pick-up truck shown in a side view. Fig. Figure 1 shows a roof rack device 100 for a vehicle 200. Here, the vehicle 200 is shown in a front view and the roof rack device 100 is in a loading position.

[0060] The roof rack device 100 comprises a base support element 3, an extension support element 5, and an extension element 6, which is attached to the roof 2 of the vehicle 200. The roof rack device 100 is attached to the vehicle 200 by means of a fastening device 4.

[0061] In its intended use, the extension support element 5 is arranged in a first position above the base support element 3, parallel to it, and in a second position pivoted upwards relative to the base support element 3. The extension support element 5 is pivotally mounted on a pivot joint 12 relative to the base support element 3, allowing it to pivot on one side. In the loading position of the Fig. 1 The extension support element 5 is pivoted relative to the base support element 3.

[0062] The extension element 6 is slidably arranged relative to the extension support element 5. In its intended use, the extension element 6 is in a first position located in or on the extension support element 5, and in a second position, it is extended along one longitudinal side of the extension support element 5 perpendicular to the direction of travel, so that a surface of the extension element 6 increases a surface of the extension support element 5.

[0063] The total area of ​​the extension support element 5 and the extension element 6 is twice as large as the area of ​​the extension support element 5 when extended.

[0064] In the charging settings of the Fig. 1 the extension element 6 is in the second position and is arranged pulled out perpendicular to the direction of travel on one longitudinal side of the extension support element 5.

[0065] The base support element 3 has a pivoting device 110 which can pivot the extension support element 5 from the first to the second setting and from the second to the first setting. Furthermore, any desired setting between the first and second settings can be secured and adjusted with minimal effort using a first adjustment device. "Secured" here means that the roof rack device 100 remains stationary without external force being applied. "Minimal effort" means that a person of average strength can make this adjustment with one hand.

[0066] The pivoting device 110 has a lifting element 30, and the first adjustment device has a threaded rod 9 arranged perpendicular to a pivoting axis, which is mounted between two receptacles 10 in the extension support element 5. The lifting element 30 has a spindle nut 13 at one end, with the end of the lifting element 30 bearing the spindle nut 13 being articulated to the threaded rod 9 by means of the spindle nut 13. Furthermore, an end of the lifting element 30 opposite the spindle nut 13 is articulated to a predetermined location 14 of the extension support element 5. This causes a rotational movement of the threaded rod 9 to move the end of the lifting element 30 bearing the spindle nut 13 perpendicular to the direction of travel, thereby raising or lowering the extension support element 5.

[0067] Furthermore, the extension carrier element 5 has a sliding device 120 which can move the extension element 6 from the first to the second setting and from the second to the first setting.

[0068] The sliding device 120 has a rail element 11 in which the extension element 6 is guided, so that the extension element 6 can be moved from the first setting to the second setting and from the second to the first setting.

[0069] The sliding device 120 also has a second adjusting device with which the sliding device can be adjusted between the first and the second setting.

[0070] The second adjustment device has a second threaded rod 29, which runs parallel to the rail element 11 and is mounted between two receptacles 10 in the extension element 6. The second threaded rod 29 passes through a second spindle nut 8, which is located on the extension support element 5 in or on a pivot joint 12 for pivoting the extension support element 5 relative to the base support element 3. A rotational movement of the second threaded rod 29 causes it to move relative to the second spindle nut 8, thus moving the extension element 6 within the rail element 11 relative to the extension support element 5.

[0071] The transported goods 15 can be reversibly and releasably attached to or in the extension element 6 using a fixing aid 16 and lashing eyes 17.

[0072] The extension support element 5 and the extension element 6 are designed to accommodate a transported item 15 weighing up to 200 kg. The weight of the roof rack device 100 is less than 100 kg.

[0073] In the Fig. In the view of the loading position shown in Figure 1, the transported goods 15 can be easily attached to or on the extension element 6 by a user of the roof rack device 100 standing on the ground 202 using the fixing aid 16 or the lashing eyes 17.

[0074] To rotate the second threaded rod 29, either a crank 7 or a cordless screwdriver can be attached to one end of the second threaded rod 29. The second threaded rod 29 can then be rotated manually or with the cordless screwdriver, so that the extension element 6 is moved from the second setting to the first setting, thus achieving the stroke setting which is in Fig. 2 is shown.

[0075] To adjust the stroke of the Fig. 2 into the transport setting of the Fig. To reach position 3, a crank 7 or a cordless screwdriver is attached to one end of the threaded rod 9, causing this threaded rod 9 to rotate, which lowers the lifting element 30 and moves the pivoted extension support element 5 in the direction of the arrow. Fig. 2 is moved onto the base support element 3 until the extension support element 5 is positioned above the base support element 3, parallel to it, in the first position. In this position, the roof rack 100 is in the transport position and loaded. When the crank 7 or the cordless screwdriver is removed from the threaded rod 9, the roof rack 100 is in the transport position and ready for driving, see [reference]. Fig. 4. This transport setting is in Fig. 7 shown as a top view.

[0076] If one starts from the perspective of the Fig. 3. When the extension element 6 is moved by means of the crank 7 from the first position, in which the extension element 6 is arranged in the extension support element 5, to the second extended position, the roof rack device 100 is then in a usage position in which, for example, a user can live or camp, see Fig. 5. This usage setting is in Fig. 8 shown as a top view.

[0077] In this setting, where the pivoting device 110 is arranged in a first position, i.e., not pivoted, and the extension element 6 is extended, a support element 23 can be arranged between the floor 202, on which the vehicle 200 is arranged, and the extension element 6 by means of a support receptacle 24, so that the space between the floor 202 and the extension element 6 can be used for occupancy, see Fig. 6. In particular, the extension element 6 can be used as an awning. Furthermore, the upper surface of the extension element 6 can be used for sitting.

[0078] Furthermore, the roof rack device 100 can have at least one side wall which can be arranged between an outer wall of the vehicle 200 and the support element 23. The side wall can be arranged parallel or perpendicular to the outer wall of the vehicle 200.

[0079] The Fig.Figure 9 shows the roof rack device 100, which is specifically suitable for a pickup truck 204. A front portion of the base carrier element 3 is attached to the front roof 2 of the pickup truck 204. A rear portion of the base carrier element 3 is attached to the upper end of an additional support 31 of the pickup truck 204 using the fastening device 4. A lower portion of the additional support 31 is mounted on a loading platform 32 of the pickup truck 204. The use of the roof rack device 100 according to the invention on a pickup truck 204 is particularly advantageous because the loading platform 32 of the pickup truck 204 can continue to be used exactly as it was before the roof rack device 100 was installed.
