[0001] Mounting device for mounting on a vehicle roof
[0002] Technical area
[0003] The present invention relates to an attachment device for mounting on a vehicle roof. The attachment device can, in particular, be a roof tent for accommodating people on a vehicle roof.
[0004] State of the art
[0005] The prior art proposes various mechanisms for setting up and folding roof tents. For example, US Pat. No. 4,366,979 teaches a roof tent with a cord attached to the top for folding the roof tent. WO 2013 / 066228 A1 relates to a transport box with a lower part, an upper part, and an intermediate part made of a flexible material, wherein the intermediate part can be pulled into the center of the transport box using drawstrings to close the transport box. Furthermore, roof structures for vehicles are known, for example, from CN 204 850 673 and KR 101 771 155, which can be closed by turning a mechanical component, such as a crank.
[0006] Description of the invention
[0007] In a first aspect, the invention relates to an attachment device for mounting on a vehicle roof. The attachment device can be a roof tent for accommodating people or a transport box for transporting goods. The attachment device can have an unfolded state and a folded state. In the unfolded state, it can be provided that the attachment device can accommodate people and / or goods. In the folded state, it can be provided that the attachment device can be transported on the vehicle roof, in particular while the vehicle is moving. The vehicle roof can be the roof of a passenger car, a truck, or another transport vehicle. For example, the vehicle roof can be the roof of an off-road vehicle. Alternatively, the vehicle roof can also be the roof of a minibus or coach, or another vehicle roof.The attachment device can be mounted on the vehicle roof, in particular detachably, using a mounting device. For example, the attachment device can be mounted on a roof rack mounted on the vehicle roof. The roof rack can be mounted on a roof rail, preferably on two parallel roof rails, of the vehicle. The roof rail can be a roof rail that is essentially integrated into the vehicle roof, a so-called "flush rail," and / or a roof rail that is provided at a distance from the vehicle roof, a so-called "raised rail."
[0008] The attachment device has two device sections which are movable relative to one another and which, when the attachment device is mounted on the vehicle roof, can extend transversely to the vehicle roof. The device sections can form sections of an outer shell of the attachment device. Alternatively or additionally, the device sections can be mechanically connected to an outer shell of the attachment device. At least one of the device sections can be designed such that it can be mounted on the vehicle roof. By moving the device sections relative to one another, the attachment device can be opened and closed. The device sections can be moved translationally and / or rotationally towards or away from one another when the attachment device is opened and closed.When the attachment device is mounted, one of the two device sections can be mounted on the vehicle roof, for example, on a luggage rack of the vehicle roof. The vehicle roof can have a longitudinal extension direction in the direction of travel of the vehicle and a transverse extension direction that extends transversely, for example, orthogonally, to the longitudinal extension direction.
[0009] The attachment device further comprises a traction means, which is preferably mechanically operatively connected to the two device sections. The traction means can have a longitudinal extension along which the traction means can be gripped and pulled by a user. The traction means can be rigid or flexible. The traction means can be mechanically operatively connected directly to the device sections, for example via a specially designed shape and / or recess in the device sections. Alternatively, the traction means can be in contact with a connecting element, such as an eyelet, a rolling element, or an extension attached to the device sections. The connecting element can in turn be connected to the device sections. Thus, the traction means can be indirectly mechanically operatively connected to the device sections via the connecting element.When the pulling device is pulled by a user standing on the ground next to the vehicle, the two device sections are moved towards each other. The pulling device can be grasped and pulled by a user, for example along its longitudinal extent. This shortens a section of the pulling device located between the device sections, allowing the device sections to be moved towards each other. The user can stand next to the vehicle, in particular at the height of the vehicle doors. Depending on the length of the pulling device, the user standing on the ground can be at a distance of, for example, 0.1 m, 0.5 m, 0.8 m, 1 m or 2 m from the vehicle when pulling the pulling device.
[0010] The user's pulling direction can be divided into several directional components, for example, a horizontal, a vertical, and a resulting direction. The horizontal direction can coincide with the transverse direction of the vehicle roof. When the pulling device is pulled transversely to the vehicle roof, the resulting pulling direction has a directional component transverse to the vehicle roof, but can also have other directional components. For example, the pulling can occur at an angle to the vehicle roof. The device sections are preferably moved toward each other when the pulling device is pulled by the user transversely to the vehicle roof or even in any direction.
[0011] The attachment device of the present invention can be closed easily and efficiently by a user. In particular, the present invention allows the attachment device to be closed even when the user is standing on the ground next to the vehicle. As a result, the operating comfort of the attachment device is increased for the user. According to one embodiment, the device sections move towards one another parallel in a sectional plane by pulling the pulling means. The sectional plane runs normal to the vehicle roof and can be arranged in the transverse or longitudinal direction of the vehicle roof. The device sections can move parallel to one another in the sectional plane during their entire relative movement, for example during the complete closing and / or opening process of the attachment device. In particular, the device sections do not tilt relative to one another in the sectional plane during the closing process.The device sections can be moved towards each other in a translational and / or rotational manner.
[0012] According to a further embodiment, the attachment device further comprises a deflection element for deflecting the traction means, which is arranged on one of the device sections. The deflection element can be arranged and configured on the device section in such a way that the traction means changes its direction of extension along the attachment device by interacting with the deflection element. The deflection element can be, for example, an eyelet through which the traction means can slide. Alternatively, the deflection element can be, for example, a roller over which the traction means is guided. By means of the deflection element, the mechanical operative connection between the traction means and the device section can be established in a particularly simple manner. The deflection element leads to relatively large forces and therefore allows comfortable operation.
[0013] According to a further embodiment, the attachment device further comprises a further deflection element for deflecting the traction means, which is arranged on the other device section. The further deflection element can be designed analogously to the deflection element. In particular, the deflection element and the further deflection element can be arranged at a predetermined distance and / or a predetermined orientation relative to one another on the respective device sections. This can make it easier for the user to pull the traction means and / or to move the device sections relative to one another. In one embodiment, the attachment device has only the two and no further deflection elements. The two deflection elements lead to particularly large vertical forces and thus allow particularly comfortable operation.According to a further embodiment, the traction means is fixed to one of the installation sections, in particular to an end section of the installation section, and runs along both deflection elements. An end section of the installation section can hereby designate the region which outwardly delimits the installation section, in particular along its direction of extension. The traction means can be riveted, glued, clamped, screwed to the installation section, for example, and / or accommodated in a fixing element arranged on the installation section. The traction means can be fixed to the installation section which faces away from the vehicle roof. This arrangement can predetermine a course or path of the traction means relative to the two installation sections.
[0014] According to a further embodiment, the deflecting element and / or the further deflecting element are arranged on the respective device section in such a way that, when the user pulls the traction means, the device sections can be moved towards one another such that they are arranged parallel to one another in the section plane defined above. For example, the device sections can be moved towards one another in a translational manner. Within the scope of this embodiment, the deflecting elements can, for example, be arranged relative to one another and relative to the fixing on the device section in such a way that only vertical forces act on the device section facing away from the vehicle roof, for example by the horizontal force components compensating one another. This arrangement of the deflecting elements prevents the device sections from tilting relative to one another, for example in the section plane, when the traction means is pulled.
[0015] According to a further embodiment, the traction means is a flexible, in particular rollable, element and more particularly a belt and / or rope. The traction means can preferably be rolled up in such a way that it can be folded together essentially in a circle along its longitudinal extent. The rope can have a symmetrical, for example round or square, cross-section. The rope can be a rope made of synthetic or natural fibers and / or a wire rope. The traction means can also be a chain. The traction means can be a belt, for example, if the traction means has an essentially rectangular cross-section. Due to the flexibility of the traction means, it can be brought into mechanical operative connection with the device sections in a particularly simple manner.Alternatively, the traction means may also be a non-retractable element, for example rod elements that are movable relative to one another and may be made of metal and / or plastic.
[0016] According to a further embodiment, the device section cuts are boundary surfaces, in particular an upper side and a lower side, of the attachment device, which are arranged parallel to one another, for example when the attachment device is folded in and / or unfolded. The device sections can be boundary surfaces, for example, if they form an outer shell of the attachment device, at least in sections. It can be provided that the underside of the attachment device can be connected to the vehicle roof, in particular can be mounted thereon, for example by means of a roof rack. Furthermore, it can be provided that the upper side is arranged above the underside in a direction perpendicular to the vehicle roof. By pulling the pulling means, the boundary surfaces of the attachment device are moved towards one another, whereby the attachment device can be closed in a particularly simple manner.The boundary surfaces can be moved toward each other on only one side, for example, the front side, when the traction device is pulled. Alternatively, the boundary surfaces can be moved toward each other as a whole. The boundary surfaces can be moved toward each other parallel to each other. Alternatively or additionally, the boundary surfaces can be pivoted relative to each other.
[0017] According to a further embodiment, the device sections are essentially solid. For this purpose, the device sections can be made of a solid material that does not deform under its own weight. Likewise, the device sections can be reinforced so that they do not deform under their own weight. The device sections can, for example, be made of plastic. They can be reinforced by a frame. A foldable material can be provided between the device sections. A foldable material can be understood to be a material that deforms due to its own weight. The foldable material can be a fabric, for example, tent fabric. Due to the foldable material, the attachment device can be folded compactly for transport purposes and at the same time easily unfolded to accommodate objects or people.When folded, the device sections can lie against each other, whereby the foldable material can be accommodated in an interior space spanned by the device sections.
[0018] According to one embodiment, the foldable material has a window and / or access surface. In this embodiment, the attachment device has a retaining element which pulls the pulling means away from the window and / or access surface when not actuated. A window surface of the foldable material can be understood as a section thereof which is at least partially transparent, in particular to visible light, and more particularly in both directions. For example, the window surface can be a recess in the foldable material which is covered with a transparent material. An access surface of the foldable material can be understood as a recess in the same through which a user gains access to an interior of the attachment device. The access surface can be closed, for example, using a zipper system.The retaining element can be designed to be flexible, in particular rollable, analogous to the traction device. The retaining element can be an elastically deformable element that functions as a spring. For example, the retaining element can be fixed to an end section of one of the device sections and, in the non-actuated state, pretension the traction device toward this end section, so that it is pulled away from the window and / or access area. This design can make it easier for a user to see through the window or access the interior of the attachment device.
[0019] According to a further embodiment, the attachment device is further equipped with a pretensioning means, by means of which the device sections are held at a predetermined distance from one another. By pulling the pulling means, the pretension of the pretensioning means can be overcome. The pretensioning means can be, for example, a hinge arranged between the device sections, which can be held at a predetermined opening angle by means of a spring force. Alternatively or additionally, the pretensioning means can be rod elements arranged between the device sections, which are displaceable relative to one another and can be held at a predetermined length by means of a spring force. Other forms of pretensioning elements are also conceivable.By pulling the tensioning device, a force can be applied to the attachment sections that counteracts the preload force, for example, the spring force of the hinge. The attachment can thus be preloaded into an open position by means of the preloading device. By pulling the tensioning device, the attachment can be moved into a closed position, counter to the preload force.
[0020] In a second aspect, the invention relates to a method for closing an attachment device mounted on a vehicle roof, in particular an attachment device according to the first aspect described above. In particular, the attachment device has a pulling means according to the first aspect. The method comprises pulling the pulling means by a user standing on the ground next to the vehicle, in particular in a direction transverse to the vehicle roof, further in particular in any direction, in order to move the two device sections of the attachment device towards one another. By means of the method, the attachment device can be closed on a first side. Subsequently, the attachment device can be closed on a further side, for example an opposite side, using the same method. The further side can also be closed in a different way.Furthermore, in one embodiment, all sides of the attachment device are closed simultaneously by pulling the traction mechanism. For example, the top and bottom sides of the attachment device can be moved toward each other in parallel by pulling the traction mechanism to simultaneously close all sides.

[0029] Detailed description of embodiments
[0030] Figure 1a schematically shows an attachment device in the form of a roof tent 10 according to one embodiment of the invention. The roof tent 10 serves to accommodate people and can be mounted on a vehicle roof (not shown). In an embodiment (not shown), the attachment device can also be a transport box for accommodating and transporting objects, such as luggage or sporting goods. The transport box can also be mounted on a vehicle roof, analogous to the roof tent 10.
[0031] The roof tent 10 has at least two installation sections 12, 14. In the embodiment of Figure 1a, the installation sections 12, 14 are shown as oppositely arranged boundary surfaces which at least partially delimit the roof tent 10 to the outside. As shown by way of example in the embodiment of Figure 1a, the installation sections 12, 14 can be, for example, an upper side 12 and a lower side 14 of the roof tent 10. The lower side 14 of the roof tent 10 can be mounted on the vehicle roof, for example on a roof rack (not shown). In the embodiment shown, the installation sections 12, 14 are made of a solid material and are movable relative to one another. The upper side 12 and the lower side 14 of the roof tent 10 are rectangular and of essentially the same size.
[0032] A foldable material 16 is arranged between the installation sections 12, 14. The embodiment of Figure 1a shows the roof tent 10 in an unfolded state. In the unfolded state, an interior space 18 of the roof tent 10 is delimited by the installation sections 12, 14 and the foldable material 16. People can be accommodated and / or objects can be stored in the interior space 18 of the roof tent 10. To fold the roof tent, the installation sections 12, 14 can be moved towards one another in the direction of arrow R, whereby the foldable material 16 is folded together. This movement allows the roof tent 10 to be brought into a folded state (not shown). In the folded state, the roof tent 10 can be transported, for example, on the vehicle roof while the vehicle is driving.
[0033] Figure 1b shows the roof tent 10 in the unfolded state, but without the foldable material 16. As can be seen from the illustration in Figure 1b, pre-tensioning means 20 are arranged between the top side 12 and the bottom side 14 of the roof tent 10 to maintain the unfolded state. The pre-tensioning means 20 are shown in the illustration in Figure 1b in the form of hinges 20, which define a predetermined opening angle by means of a spring element 22. The hinges 20 can be used to hold the top side 12 and the bottom side 14 at a predetermined distance D. The roof tent has a total of four pre-tensioning means 20, which are arranged at the respective corners of the roof tent.
[0034] Furthermore, the roof tent 10 in the embodiment of Figure 1b has a traction means 24 and two deflection elements 26a, 26b. In this embodiment, the traction means 24 is designed in the form of a roll-up belt 24. The traction means 24 is fixed to an end section 12a of the upper side 12 of the roof tent 10, in the present embodiment to the front side of the roof tent. Starting from the end section 12a of the upper side 12, the traction means 24 extends between the installation sections 12, 14 and changes its direction of extension by deflecting at the deflection elements 26a, 26b. Finally, the traction means 24 protrudes from the underside 14 of the roof tent 10 with a projection 24a. In the present embodiment, this projection 24a is provided on the underside 14 diagonally opposite to the fixation of the traction means 24 on the upper side 12.This projection 24a of the traction device 24 can be grasped by a user, such as a driver of the vehicle, and used to pull the traction device 24. The arrangement and mode of operation of the traction device 24 is explained in more detail with reference to Figure 2.
[0035] Figure 2 schematically shows the roof tent 10 of Figures 1a and 1b in a front view. As can be seen from the illustration in Figure 2, the tensioning means 24 runs between the top side 12 and the bottom side 14 of the roof tent 10. One of the deflecting elements 26a and 26b is arranged on the top side 12 and the bottom side 14, respectively. In Figure 2, the deflecting elements 26a and 26b are shown as rollers over which the tensioning means 24, shown as a belt, is tensioned. Furthermore, the tensioning means 24 is fixed to an end section 12a of the top side 12 of the roof part 10.
[0036] Due to the fixation of the traction means 24 at the end section 12a and the deflection at the rollers 26a, 26b, a resulting force is applied to the upper side 12 when the traction means 24 is pulled. The arrangement of the deflection elements 26a, 26b is such that the resulting force F is a force acting in the vertical direction. In the illustration in Figure 2, the rollers 26a, 26b are arranged on the upper side 12 and the lower side 14 of the roof tent 10 in such a way that the horizontal components of the forces acting on the upper side 12 cancel each other out. As a result, the distance D between the upper side 12 and the lower side 14 is uniformly reduced along the end face of the roof tent, which runs in the transverse direction Q of the vehicle roof.In other words, the arrangement of the rollers 26a and 26b shown in Figure 2 prevents the installation sections 12, 14 from tilting relative to one another in a sectional plane that is arranged normal to the vehicle roof and runs parallel to the transverse direction Q when the traction device 24 is pulled. The installation sections 12, 14 thus move towards one another in this sectional plane such that they are always arranged parallel during the relative movement. As already mentioned in connection with the embodiment of Figure 1b, the traction device 24 protrudes from the underside 14 of the roof tent 10 with a projection 24a. A user standing next to the vehicle can grasp the traction device 24 at this projection 24a and pull it in any direction. The user does not have to climb onto the vehicle, but can pull the traction device 24 while standing next to the vehicle.Closing the roof tent 10 is thus made easier for the user by the present invention.
[0037] Figure 3 shows the roof tent 10 according to a further development. Here, a window area 28 is provided in the foldable material 16. The window area 28 is designed in the form of a recess in the foldable material 16, which is covered with a material transparent to visible light. For example, the recess in the foldable material 16 can be covered with a mesh. Through this mesh, the user can look out of the interior 18 of the roof tent 10. At the same time, the mesh can prevent dirt and / or insects from entering the interior 18 of the roof tent 10. Alternatively or additionally, the roof tent 10 can also be provided with an access area through which the user gains access to the interior 18 of the roof tent 10.
[0038] To improve the user's view through the window area 28, the roof tent 10 according to the embodiment of Figure 3 is further provided with a retaining element 30. The retaining element 30 is shown in Figure 3 in the form of a flexible belt, which is mechanically connected to the tensioning means 24. The belt 30 is fixed to the end section 12a of the upper side 12 of the roof tent 10. If the tensioning means 24 is not pulled, the retaining element 30 pretensions the tensioning means 24 towards the end section 12a. As a result, the tensioning means 24 is largely pulled out of the window area 28. Due to the retaining element 30, the user's field of vision is thus hardly impaired by the tensioning means 24 when looking through the window area 28. Figures 4a to 4c show further embodiments of attachment devices according to the present invention. The same reference numerals designate the same elements here.
[0039] Figure 4a shows a roof tent 10 according to a further embodiment. In contrast to the embodiment of Figures 1a to 3, in the embodiment of Figure 4a, two deflection elements in the form of rollers 126a, 126b are arranged on the outer side of the underside 14 of the roof tent 10 facing the vehicle roof. A traction means 124 is fixed at two points on the upper side 12 of the roof tent 10 and is deflected on the rollers 126a, 126. The deflected traction means 124 protrudes with the overhang 24a from the underside 14 of the roof tent 10. Otherwise, the roof tent of the embodiment of Figure 4a is designed analogously to the roof tent 10 according to the embodiments of Figures 1a to 3.
[0040] Figure 4b shows a roof tent 10 according to a further embodiment. In contrast to the embodiments of Figures 1a to 3, in the embodiment of Figure 4b, a deflection element in the form of a roller 226 is arranged centrally on the underside 14 of the roof tent 10 facing the vehicle roof. A traction means 224 is fixed at two points on the upper side 12 of the roof tent 10 and is deflected on the roller 226. The deflected traction means 224 protrudes with the overhang 24a from the underside 14 of the roof tent 10. Otherwise, the roof tent of the embodiment of Figure 4b is designed analogously to the roof tent 10 according to the embodiments of Figures 1a to 3.
[0041] Figure 4c shows an attachment device in the form of a transport box 110 according to a further embodiment. The transport box is designed to accommodate objects such as luggage or sporting goods, for example skis, and has a top side 112 and a bottom side 114. The top side 112 and the bottom side 114 of the transport box 110 are pivotally connected relative to one another at one end section along a long side of the box by a connecting element (not shown). At the opposite end section along the long side, the top side 112 and the bottom side 114 are not connected to one another. In the embodiment of Figure 4c, the transport box 110 is open on one side to allow a user access to the interior 118 of the transport box 110. A deflection element in the form of a roller 326 is arranged on the bottom side 114 of the transport box 110.A traction device 324 is fixed to an end section 112a of the top side 112 of the transport box 110. The traction device 324 is deflected on the roller 324 and protrudes from the bottom side 114 of the transport box 110 with the projection 24a. A user standing next to the vehicle can grasp the traction device at this projection 24a and pull it in any direction. By pulling the traction device 324, the top side 112 and the bottom side 114 are moved toward each other such that they are arranged parallel to each other in a sectional plane that is normal to the vehicle roof, i.e., perpendicular to the plane of the page, and runs in the longitudinal direction of the vehicle roof.
[0042] Figure 5 shows a flowchart with steps of a method for closing an attachment device mountable on a vehicle roof according to one embodiment of the invention. The attachment device is designed according to one of the embodiments of Figures 1a to 4c. In particular, the attachment device has a traction device according to the embodiments of Figures 1a to 4c.
[0043] The method begins with a user standing on the ground next to the vehicle pulling S1 of the traction device, in particular in a direction transverse to the vehicle roof, and further in particular in any desired direction, in order to move the two device sections on one side of the attachment device towards one another. The method further comprises moving S2 of the two device sections on a second side of the attachment device, in particular opposite the first side. The first side can be arranged above a windshield of the vehicle. The first side is therefore difficult for the user to access. The second side can be arranged above a rear end or a trunk of the vehicle. The second side of the attachment device is therefore easier for the user to reach than the first side.Performing this procedure allows the user to close the attachment device mounted on the vehicle roof on the first side without having to climb onto the vehicle.
