Description

State of the art

[0001] The invention relates to a fastening device according to the preamble of claim 1 and a modular system for manufacturing a fastening device according to claim 10.

[0002] A fastening device for a vehicle has already been proposed, which includes one-piece angles for connecting an interior fitting of the vehicle to a structural component of the vehicle.

[0003] From the documents DE 10 2011 114 098 A1, DE 10 2009 008 188 A1, DE 10 2010 051 556 A1, DE 10 2011 107 080 A1, DE 299 20 497 U1, US 2006 / 0 261 695 A1 and EP 2 713 061 A1, fastening devices for vehicles are already known, comprising at least one first fastening module intended for connection with a structural component of the vehicle, and at least one second fastening module intended for fastening at least one interior fitting of the vehicle, and at least one connecting unit intended for connecting the first fastening module and the second fastening module to each other in an assembled state.

[0004] The object of the invention is, in particular, to provide a fastening device with improved flexibility. This object is achieved by the features of claims 1 and 10, while advantageous embodiments and further developments of the invention can be found in the dependent claims. Advantages of the invention

[0005] The invention relates to a fastening device for a vehicle, in particular an aircraft, comprising at least one first fastening module which is provided for a connection, in particular indirect or direct, with a structural component, in particular an inner side of the structural component, of the vehicle, and with at least one second fastening module which is provided for fastening at least one interior fitting of the vehicle.

[0006] It is proposed that the fastening device include at least one connecting unit designed to join the first and second fastening modules in their assembled state. This advantageously increases flexibility. Furthermore, assembly can be simplified, as the first and second fastening modules can be pre-assembled independently, even in hard-to-reach areas of the vehicle. Additionally, the fastening modules can be individually replaced, simplifying maintenance and / or repair. Advantageously, the fastening modules can be combined in such a way that they can be specifically adapted to structural properties, such as available mounting space, and / or material properties, such as material resistance.

[0007] The term "intended" is to be understood in particular as specifically designed and / or equipped. The fact that an object is intended for a specific function is to be understood in particular as the object fulfilling and / or performing this specific function in at least one application and / or operating state. In this context, a "fastening device for a vehicle" is to be understood in particular as a device that is advantageously specifically designed for use in a vehicle, in particular in an interior space and especially preferably in a vehicle cabin. The vehicle may in particular be a land vehicle or a watercraft and, more preferably, an aircraft, especially an airplane. The aircraft could in particular be a helicopter or an airship. Furthermore, the vehicle may be configured as a spacecraft.A "structural component" of a vehicle is understood to mean, in particular, a part of the vehicle, especially a side panel, which preferably defines the interior and, in particular, the cabin of the vehicle, and is particularly load-bearing and advantageously stiffening. A side panel is understood to mean, in particular, the side panel itself. An "interior fitting" of a vehicle is understood to mean, in particular, at least one component and, in particular, a subassembly of an interior, especially within the cabin, of the vehicle, such as, in particular, interior trim, preferably insulation, and, in particular, preferably an insulating mat. The inner side of the structural component is, in particular, a side of the structural component facing an interior of the vehicle. The connecting unit can be provided for at least a material-bonded connection between the first fastening module and the second fastening module.The term "material-bonded connection" is understood to mean, in particular, that components are held together by atomic or molecular forces, such as by soldering, welding, bonding, and / or vulcanizing. Preferably, the connecting unit is designed to provide at least a force-fit and / or form-fit connection between the first and second fastening modules. In this context, a "force-fit and / or form-fit connection" is understood to mean, in particular, a connection in which a holding force between two components is preferably transmitted by a geometric engagement of the components with one another and / or by a frictional force between the components. The first and / or the second fastening module is, in particular, at least partially and preferably entirely made of a plastic, preferably a heat-resistant plastic such as polyamide.Advantageously, the first fastening module and / or the second fastening module is manufactured using a single- and / or multi-component injection molding process.

[0008] Furthermore, according to the invention, the connecting unit comprises at least one rotary locking unit, which is designed to connect the first fastening module and the second fastening module to each other in a form-fitting manner. The rotary locking unit is particularly preferably designed to connect the first fastening module and the second fastening module to each other by rotating them relative to each other, particularly in the circumferential direction, by an angle of rotation of at most 180°, advantageously at most 120°, more advantageously at most 90°, preferably at most 72°, and most preferably at most 36°. A "circumferential direction" is understood to mean, in particular, a circular direction of a rotation axis of a smallest imaginary cylinder that just encloses at least one of the fastening modules, in particular the first fastening module and / or the second fastening module.The rotary locking unit advantageously forms a bayonet lock. The rotary locking unit comprises, in particular, at least one rotary locking element and preferably several rotary locking elements, and in particular, at least one corresponding rotary locking element, advantageously designed to correspond to the rotary locking element, and preferably several corresponding rotary locking elements. The rotary locking element is designed, in particular, to bear against the corresponding rotary locking element in a mounted state and, in particular, to at least partially receive the corresponding rotary locking element. The rotary locking element is arranged, in particular, on the first mounting module and / or, more preferably, the corresponding rotary locking element is arranged on the second mounting module. This allows for a simple form-fit connection.

[0009] It is further proposed that the connecting unit comprises at least one clamping unit designed to clamp the first fastening module and the second fastening module relative to each other in at least one direction, in particular at least substantially perpendicular to the circumferential direction. The term "at least substantially perpendicular" here is intended to define, in particular, an orientation of a direction relative to a reference direction, wherein the direction and the reference direction, particularly when viewed in a plane, enclose an angle of 90°, and the angle has, in particular, a maximum deviation of less than 8°, advantageously less than 5°, and most advantageously less than 2°. For clamping the fastening modules, the clamping unit comprises at least one force-application element and preferably several force-application elements, which may, in particular, be at least partially elastic.The at least one force-applying element is specifically designed to apply a force to at least one element, preferably at least one element of the rotary locking unit, in particular the rotary locking element and / or the corresponding rotary locking element. Preferably, the force-applying element is designed as a chamfer. The force-applying element is preferably arranged on the second fastening module. This allows for a simple force-fit connection. Furthermore, vibrations and the associated noise generation can be avoided.

[0010] It is further proposed that the rotary locking unit and the clamping unit be formed at least partially as a single piece. In this context, the phrase "at least partially as a single piece" refers specifically to the fact that at least a part of the first object is integrally connected to at least a part of the second object, and preferably formed in this way. Preferably, the corresponding rotary locking element of the rotary locking unit is integrally formed with the force-application element of the clamping unit. "Integrated" refers specifically to a material bond, for example, by welding, bonding, injection molding, and / or any other process that would be considered appropriate by a person skilled in the art. Advantageously, "integrated" should also be understood to mean "one-piece."The term "one-piece" is understood to mean, in particular, formed in a single piece, such as by manufacturing from a single casting and / or by manufacturing using a single- or multi-component injection molding process, and advantageously from a single blank. This allows for a simple way to create a force-fit and / or form-fit connection.

[0011] Furthermore, according to the invention, the rotary locking unit comprises a number of rotary locking elements, in particular the aforementioned rotary locking elements, preferably corresponding rotary locking elements and / or, most preferably, force-actuating elements, which are arranged circumferentially offset from one another, preferably rotationally symmetrically, by an angle corresponding to 360° divided by the number of rotary locking elements, in particular the aforementioned rotary locking elements, preferably the corresponding rotary locking elements and / or, most preferably, the force-actuating elements. In particular, the angle corresponds to the rotation angle. This further simplifies assembly. In particular, the rotationally symmetrical arrangement of the rotary locking elements enables a Poka-Yoke solution.

[0012] It is further proposed that the first fastening module has at least one receiving area for the second fastening module. The rotary locking element, in particular, at least partially delimits the receiving area. Specifically, the rotary locking element forms at least one stop, preferably a stepped one, for the corresponding rotary locking element. During assembly of the fastening device, the second fastening module can be at least partially inserted into the receiving area, in particular by moving the first and second fastening modules relative to each other and at least substantially perpendicular to the circumferential direction, especially along the axis of rotation, and subsequently by rotating the first and second fastening modules relative to each other and at least substantially parallel to the circumferential direction.The term "at least substantially parallel" here refers in particular to an alignment of a direction relative to a reference direction, especially in a plane, wherein the direction relative to the reference direction has a deviation of less than 8°, advantageously less than 5°, and particularly advantageously less than 2°. This allows for a precise arrangement of the first and second mounting modules relative to each other during assembly. In particular, the stability of the connection between the first and second mounting modules can be improved.

[0013] According to the invention, it is proposed that the connecting unit comprises at least one anti-rotation device, which is designed to prevent, and in particular block, rotation of the second fastening module relative to the first fastening module, in particular at least substantially parallel to the circumferential direction and preferably against a mounting direction, in the assembled state. Preferably, a connection made by means of the anti-rotation device can only be permanently disconnected non-destructively by rotating the first fastening module and the second fastening module relative to each other. The anti-rotation device comprises, in particular, at least one detent element and at least one corresponding detent element designed to correspond to the detent element.

[0014] Preferably, the corresponding locking element is designed as a detent. Preferably, the locking element is arranged on the second mounting module and / or the corresponding locking element is arranged on the first mounting module. Particularly preferably, the anti-rotation unit is arranged at least partially circumferentially between the rotary locking unit. The locking element is particularly arranged circumferentially between two corresponding rotary locking elements. Furthermore, the corresponding locking element is particularly arranged between two rotary locking elements. This ensures a backlash-free connection. Furthermore, uncontrolled loosening of the connection, such as that caused by vibrations during vehicle operation, can be prevented. Operational reliability can be improved.

[0015] To simplify disassembly, particularly for maintenance and / or repair, of the fastening device, it is proposed that the connecting unit include an indicator designed to show the position, particularly an angular position in the circumferential direction, of the anti-rotation unit, especially the detent element and preferably the corresponding detent element. The indicator is arranged, in particular, on the second fastening module. The indicator is arranged, in particular, perpendicular to the circumferential direction relative to the detent element.

[0016] It is further proposed that the connecting unit include at least one auxiliary unit designed to at least assist in the disassembly of the first and second fastening modules. The auxiliary unit is arranged on the first fastening module and is preferably designed as a recess, advantageously in the first fastening module, particularly perpendicular to the circumferential direction. The auxiliary unit is specifically designed to allow a user to release the anti-rotation device, particularly by means of a tool, by deflecting the locking element at least substantially perpendicular to the circumferential direction and, in particular, perpendicular to the axis of rotation. This further simplifies the disassembly of the fastening device, especially for maintenance and / or repair.It is further proposed that the fastening device comprise a third fastening module, which is connectable to at least the first fastening module and is designed to connect it to the structural component. The third fastening module is advantageously designed as an insert for the first fastening module. The third fastening module is specifically designed to be directly connected to the first fastening module, and particularly to the structural component, by means of a material-fit, form-fit, and / or force-fit connection, preferably by means of a press fit. Preferably, the third fastening module is made of a different material than the first fastening module and / or the second fastening module. The choice of material for the third fastening module is preferably dependent on the material of the structural component to which the first fastening module is to be connected.The third fastening module is particularly preferably made of a metal, especially aluminum and / or titanium. Furthermore, the third fastening module can be provided with a coating, particularly a metallic or metal-containing coating, especially a metallic or metal-containing coating that differs from the base material. The coating can advantageously be applied electroplated or by other means. If the structural component is made of a plastic, especially a glass fiber reinforced plastic, the third fastening module is advantageously made of aluminum. Particularly if the structural component is made of carbon fiber, the third fastening module is advantageously made of titanium. The aforementioned choice of material for the third fastening module is particularly advantageous for aircraft, preferably airplanes.Particularly in other vehicles, additional materials, especially material pairings, could be advantageous for the third mounting module and the structural component, whereby corrosion resistance and, preferably, electrical contact properties must be taken into account when selecting the materials. The third mounting module is advantageously manufactured using a machining and / or forming process. This ensures a stable connection of the mounting device to the structural component.

[0017] According to the invention, the rotary locking unit and the rotary locking unit are at least partially formed integrally. In particular, the corresponding detent element is integrally connected to the rotary locking unit. Preferably, the rotary locking unit, in its assembled state, forms a stop for the detent element. This simplifies the design.

[0018] In a preferred embodiment of the invention, it is proposed that the first fastening module and the connecting unit, in particular the rotary locking unit, the clamping unit, and / or the locking unit, are at least partially formed integrally. Preferably, at least the auxiliary unit of the connecting unit, at least the rotary locking element of the rotary locking unit, and / or at least the corresponding detent element of the locking unit, are integrally connected to the first fastening module. This eliminates the need for additional components, reduces costs, and further simplifies manufacturing and assembly.

[0019] In a particularly preferred embodiment of the invention, it is proposed that the second fastening module and the connecting unit, in particular the rotary locking unit, the clamping unit, and / or the locking unit, are at least partially formed integrally. Preferably, at least the indicator element of the connecting unit, at least the corresponding rotary locking element of the rotary locking unit, at least the force-applying element of the clamping unit, and / or at least the detent element of the locking unit are integrally connected to the second fastening module. This eliminates the need for additional components, reduces costs, and further simplifies manufacturing and assembly.

[0020] In a further aspect of the invention, a modular system for manufacturing a fastening device according to the invention is proposed, comprising a fastening module set for each of the respective fastening modules. In this context, a "fastening module set" is understood to be a modular set comprising at least one, preferably several, corresponding modules, such as the first, second, and / or third fastening module. Preferably, however, the fastening modules of a fastening kit differ in at least one characteristic. In particular, the fastening modules of a fastening kit can be designed to perform different functions and advantageously include various parts for fastening the internal components, such as eyelets for holding cables and / or threads for connection with various screw-on parts.This can further improve flexibility.

[0021] Furthermore, it is proposed that the individual mounting modules of at least one mounting module set differ from one another by at least one material, at least one shape, and / or at least one color. In particular, the mounting modules of a kit can be distinguished from one another by color, especially color coding. This allows the mounting device to be adapted particularly flexibly to specific assembly and operating conditions.

[0022] The fastening device is not intended to be limited to the application and embodiment described above. In particular, the fastening device may, to fulfill a function described herein, have a different number of individual elements, components, and units than specified herein. Drawings
