Description

Technical Field

[0001] The present invention relates to the installation of so-called monuments in a vehicle cabin, such as the passenger cabin of an aircraft. These are modules with different functions that can be installed at different locations in the cabin and, for example, form an onboard kitchen (so-called galley), sanitary facilities, or other equipment items for the interior. Background Art

[0002] Equipment items (Ausstattungsgegenstand), such as displays, indicator boards, etc., can be attached to the wall sections of such buildings. Typically, such frames are used, which are screwed onto the wall sections from the front and serve as partitions for the edge areas of the attached equipment items. Such frames typically extend significantly beyond the corresponding building and do not terminate flush with it, which, on the one hand, results in an uneven appearance and, on the other hand, creates corners and edges that could become entrapped. Furthermore, the screws used for fastening are visible and therefore cannot be protected from unauthorized access. The frame must be positioned correctly and held in place during fastening, so installation is typically relatively laborious. If maintenance work is to be performed on an attached equipment item or if this equipment item is to be replaced, the frame must be unscrewed. Furthermore, the fasteners of the equipment item, such as the screws, with which it is screwed onto the wall section of the building, must be loosened. In particular, in many cases, access to the back of the equipment item is necessary because interfaces for connecting to onboard electronics are provided there. Therefore, maintaining equipment items can be time-consuming and labor-intensive. Summary of the Invention

[0003] The present invention is based on the prior art and aims to provide a fastening system for attaching an item of equipment to a structure, which fastening system allows simple maintenance and reliable fastening of the item of equipment. Another object of the invention is to provide a corresponding method for attaching an item of equipment to a structure.

[0004] According to the invention, this object is achieved by a fastening system and a method for attaching an equipment item, in particular a display, to a structure provided for installation in a passenger cabin, in particular an aircraft cabin, by means of the fastening system.

[0005] One aspect of the present invention relates to a fastening system for attaching an item of equipment, such as a display, a display unit, a lighting module, a touch screen, or the like, to a structure, in particular an aircraft structure, that is designed to be installed in a passenger cabin, in particular an aircraft cabin. The fastening system comprises a wall segment of the structure, the wall segment having at least one first fastening element, and a frame having at least one second fastening element, the frame being configured to at least partially cover the item of equipment in a fastened state. The first and second fastening elements are configured to engage with each other and be movable relative to each other in a pre-assembled state, and to be fixed to each other in the fastened state, wherein the fastened state can be achieved by moving the frame relative to the wall segment in the pre-assembled state in a fastening direction that extends at least substantially parallel to a main extension plane of the wall segment.

[0006] Another aspect of the present invention relates to a method for attaching an item of equipment, such as a display, display unit, lighting module, touchscreen, or the like, to a structure, in particular an aircraft structure, designed for installation in a passenger cabin, in particular an aircraft cabin, by means of a fastening system. The fastening system comprises: a wall segment of the structure having at least one first fastening element; and a frame having at least one second fastening element, the frame being configured to at least partially retain the item of equipment in a secured state. This may be the fastening system according to the present invention. The method comprises the steps of: establishing a pre-assembled state in which the first and second fastening elements engage with each other and are movable relative to each other. Furthermore, the method comprises the steps of: in the pre-assembled state, moving the frame relative to the wall segment in a fastening direction extending at least substantially parallel to a main extension plane of the wall segment, so as to establish the secured state in which the first and second fastening elements are fixed to each other.

[0007] The invention further relates to a monument, in particular an aircraft monument, provided for installation in a passenger cabin, in particular an aircraft cabin, comprising a fastening system according to the invention and an item of equipment attached by means of the fastening system.

[0008] Furthermore, the invention relates to a cabin region having the monument according to the invention and to an aircraft having the monument according to the invention.

[0009] Advantageous features are thereby achieved in terms of fastening equipment items to buildings. A fastening system and a method can be provided which allow for quick and reliable fastening and / or simple and rapid access for servicing equipment items. Furthermore, it is possible to simply achieve that the frame ends flush with the wall section. According to the invention, narrow frames can be used which do not need to be configured as sections for joining with the aid of screws or the like, thereby maximizing the area available for equipment items. While maintaining functionality, a high degree of flexibility can be achieved in terms of the external appearance of the frame, thereby allowing the frame to be adapted to the corresponding equipment item and achieving a uniform aesthetic overall impression. Furthermore, a fastening is achieved which protects the building and equipment item from unauthorized access, since the fastening elements are inaccessible.

[0010] The first fastening element may be permanently attached to the wall segment. The first fastening element may be formed integrally with the wall segment and / or a component of the wall segment. The second fastening element may be permanently attached to the frame. The second fastening element may be formed integrally with the frame and / or a component of the frame.

[0011] The engagement of the fastening elements into one another may comprise that the first fastening element and the second fastening element at least partially overlap one another, in particular when viewed parallel to a main extension plane of the wall segment.

[0012] The wall segment may include a plurality of first fastening elements. The frame may include a plurality of second fastening elements. The number of first fastening elements may correspond to the number of second fastening elements. A respective one of the first fastening elements may be assigned to a respective one of the second fastening elements.

[0013] The main extension plane of the wall segment can be defined by a surface normal of the wall segment. The main extension plane of the wall segment can be arranged parallel to the largest side of a hypothetical smallest cuboid that completely encloses the wall segment. When the structure is installed in a cabin (e.g., an aircraft cabin), the main extension plane extends, for example, perpendicular to the cabin floor.

[0014] According to one embodiment, the first and second fastening elements, in the fastened state, prevent movement of the frame relative to the wall segment in a direction perpendicular to the main extension plane of the wall segment. Preferably, the fastening elements define a single fastening direction. The fastening elements can be designed such that, starting from the pre-assembled state, linear movement of the frame is only possible after the frame has moved a predetermined distance in the fastening direction.

[0015] The wall section may include a receiving area for equipment items. The equipment items may be partially or completely inserted into the wall section. The receiving area may be a pocket for the equipment items. In other embodiments, the wall section may be flat, and the equipment items may simply be placed onto the wall section.

[0016] The fastening direction may extend parallel to the bottom surface of the structure or parallel to the cabin floor. In other embodiments, the fastening direction may extend perpendicular to the bottom surface of the structure or parallel to the cabin floor. In some embodiments, an inclined fastening direction may also be provided.

[0017] The method according to the invention may comprise method steps for actuating, assembling, fastening, loosening or in principle operating the described elements and components of the fastening system. Likewise, the fastening system or specific elements and components of the fastening system may be configured to be able to perform the described method steps.

[0018] In particular, if the first and second fastening elements are configured to allow the frame to be brought into a pre-assembled state by moving it toward the wall segment in an assembly direction extending substantially perpendicularly to the main extension plane of the wall segment, a simple assembly of the frame can be achieved, allowing the frame to be precisely positioned or pressed in and subsequently fastened. The wall segment and / or the frame can have a guide that guides the frame during movement in the assembly direction.

[0019] For example, a load-bearing and easily achievable fastening can be achieved when, in the fastened state, the first fastening element engages the second fastening element from behind and / or the second fastening element engages the first fastening element from behind. Preferably, the engagement from behind is only achieved by moving the frame in the fastening direction and is not yet present, for example, in the pre-assembled state.

[0020] The first fastening element can be designed as a hook-shaped element. Alternatively or additionally, the second fastening element can be designed as a hook-shaped element. Thus, a reliable, easily formable, and easily loose fastening can be obtained. In addition, if specific movability is desired for preassembly and / or for fastening, the geometry of the fastening elements can be adapted in a simple manner. In some embodiments, the first fastening element and the second fastening element can be designed as corresponding hook-shaped elements that engage with each other in the fastened state. Here, the movement of the frame in the fastening direction can cause the fastening elements to hook with each other. In other embodiments, the first fastening element or the second fastening element can be designed as a slot, hole, opening, recess, etc., wherein the corresponding other fastening element engages with the first fastening element or the second fastening element at least in the fastened state. Preferably, the wall section in this case is designed to be flat and has a depression serving as the first fastening element. For example, to form the pre-assembled state, one fastening element is pushed into the other fastening element by moving the frame in the assembly direction, and in particular subsequently the first and second fastening elements are hooked into one another by displacing the frame in the fastening direction.

[0021] According to another embodiment, the first and second fastening elements can be configured to be released from one another by moving the frame relative to the wall segment from the secured state in the opposite direction of the securing. The first and second fastening elements can be provided with latching elements that engage in the secured state. Thus, releasing the fastening elements from one another may require overcoming a corresponding securing force. In other embodiments, the frame can be movable from the secured state substantially without resistance in the opposite direction of the securing. Preferably, the frame can be released from its secured state without damage, in particular without the use of tools.

[0022] The frame can be configured to at least partially or completely hold the equipment item, thereby making it possible to eliminate the need for additional fasteners for the equipment item on the wall section. For example, the frame can hold the equipment item in a receiving area. The frame can apply a holding force to the equipment item that counteracts gravity. Alternatively or additionally, the frame can prevent the equipment item from tilting. According to some embodiments, the frame can form a receiving area for the equipment item. The equipment item or at least one component of the equipment item can be fastened to the frame. In addition, the frame can also be formed integrally with the equipment item or at least with a component of the equipment item. In some embodiments, the equipment item may not be fastened to the wall section.

[0023] For example, if the fastening system also includes a locking unit that is configured to prevent the fastened state from being released in the locked state and to release the fastened state in the released state, targeted protection of the frame, for example, against unauthorized access, can be achieved. In particular, the locked state exists in the fastened state. According to the present invention, it can be provided that the fastened state cannot be released without damage from the locked state. The locking unit can be configured to prevent the frame from moving in the opposite direction of the fastening direction in the locked state. Thus, in the locked state, the frame can be prevented from any movement by the fastening elements fixed to each other on the one hand and the locking unit on the other hand.

[0024] According to one refinement, the locking unit may include at least one locking element that mechanically prevents movement of the frame relative to the wall segment in the locked state. The locking element may be configured to absorb forces acting on the frame parallel to the tightening direction. In the locked state, the locking element is preferably fixed relative to the wall segment and the frame. The locking element may be a bolt, a pin, a rod, a square, a retaining hook, or other suitable mechanical structural element. The locking element is preferably made of metal, for example, steel. The locking element may be formed separately from the wall segment and / or the frame. In other embodiments, the locking element may also be formed integrally with the frame or the wall segment. Preferably, the locking element extends perpendicular to the tightening direction in the locked state. In some embodiments, the locking element may be pre-tensioned so that when the frame is moved in the tightening direction to form the tightened state, the locking element automatically moves to the locked position.

[0025] The frame can include a first opening, and the wall segment can include a second opening aligned with the first opening in the secured state, wherein the locking element extends at least partially through the first opening and the second opening in the locked state. This allows for a mechanically simple yet reliable locking. The frame and / or the wall segment can have webs with corresponding openings.

[0026] According to an improved solution, the locking unit includes an actuating mechanism having an actuating element arranged spaced apart from the locking element and a force transmission device that mechanically couples the actuating element to the locking element, wherein the locking element is movable by means of the actuating element. This improved solution allows for simple assembly and disassembly of the frame and therefore allows for simple and quick maintenance of the equipment item. For example, the actuating element can be linearly movable to actuate the locking unit. The actuating element can be arranged behind a partition of the frame and / or wall section so that it is not visible from the outside. Therefore, how to loosen the frame can be hidden from unauthorized personnel. The force transmission device can include a cable (especially a Bowden cable) and / or a pressure rod and / or a pressure-actuated cable. The actuating element can be designed as a handle. According to one embodiment, the actuating mechanism is part of the wall section and / or the building. In other embodiments, the actuating mechanism can also be part of the frame.

[0027] In particular, high operating comfort and / or a low probability of operating errors can be achieved if the actuating element is preloaded into the locked position by means of a spring element. It may be necessary to move the actuating element against the spring force of the spring element in order to release the lock. The actuating element can be preloaded against the wall segment and / or the frame.

[0028] Furthermore, it can be provided that, in the fastened state, the frame covers the fastening element and, in particular, the locking unit in an opaque manner. For example, when viewed perpendicularly to the main extension plane of the wall segment or, for example, perpendicularly to the surface of an equipment item (e.g., a display surface), the frame can conceal the fastening element, the locking unit, and the actuating element.

[0029] If the fastening system has an actuating element, an additional partition can be provided, which is arranged next to the frame and / or above the frame and is fastened, for example, to the wall section. The partition can cover the actuating element and, in particular, other components of the locking unit.

[0030] According to one embodiment, corresponding connecting elements, such as plugs and sockets, can be formed on the equipment item and the wall section. Preferably, the connecting elements are designed to be adapted to each other, for example geometrically, so that a connection is established immediately when the equipment item is pushed and / or inserted into the receiving area.

[0042] Figure 11 An aircraft is shown, which is equipped with Figure 1 cabin area. DETAILED DESCRIPTION

[0043] Figure 1 Vehicles are shown (e.g. Figure 11 FIG. 1 shows a cabin area 10 of a passenger aircraft 100 (see FIG. 1 ). Arranged in cabin area 10 is a structure 12, which rests on and is connected to a cabin floor 14. Structure 12 is, for example, a galley module for the passenger compartment. Attached to structure 12 is an equipment item 16, which in the example shown is designed as an OLED display. However, as mentioned above, other equipment items 16 are also contemplated according to the present invention.

[0044] The equipment item 16 is attached by means of a fastening system 18. The fastening system 18 comprises a frame 20 and a wall section 22 of the monument. The frame 20 covers the equipment item 16 in its edge region. This creates the impression that the equipment item 16 is integrated into the monument 12.

[0045] Figure 2The cross-sectional view of the fastening system 18 is shown in an exploded view. The wall segment 22 comprises a first fastening element 24. In the illustrated case, the wall segment 22 comprises a plurality of first fastening elements 24, which for reasons of clarity are not all provided with reference numerals.

[0046] Furthermore, the frame 20 comprises a second fastening element 26. In the case shown, the frame 20 comprises a plurality of second fastening elements 26, which for reasons of clarity are not all provided with reference numerals.

[0047] In the exemplary case shown, the equipment item 16 comprises an OLED array 28 , a seal 30 connected thereto, a protective cover 32 and strips 34 made of PTFE (polytetrafluoroethylene), by means of which the equipment item 16 can be joined to the frame 20 .

[0048] The equipment item 16 further comprises engagement elements 36, 38 which can be introduced into corresponding receptacles 40, 42 of the wall section 22 and by means of which the equipment item 16 can be fastened to the wall section 22. The engagement elements 36, 38 can comprise, for example, threaded rods or screws.

[0049] The wall section 22 defines a main extension plane 44 which, in the installed state of the monument 12 and the fastened state of the equipment item 16, is perpendicular to the cabin floor 14 and parallel to an outwardly facing surface 46 of the equipment item 16 (see Figure 1 )extend.

[0050] The frame 20 has a partition 48 which covers the fastening elements 24 , 26 in the fastened state of the equipment item 16 .

[0051] The equipment item 16 can have, for example, an interface (not shown) at the rear side for connecting to an onboard network.

[0052] Additional reference is made below Figure 3 and Figure 4 . Figure 3 A cross-sectional illustration of the fastening system 18 is shown in a pre-assembled state. Figure 4 A cross-sectional illustration of the fastening system 18 is shown in the fastened state.

[0053] First, if necessary, the equipment item 16 is connected to the onboard network. When attaching the equipment item 16, it is first placed in the receiving area 50 of the wall segment 22. The equipment item 16 is then fastened to the wall segment 22 using the coupling elements 36, 38. The illustrated coupling using nuts is to be understood purely as an example. Alternatively, screws or other suitable fastening means can also be used as coupling elements, screwed directly into corresponding holes in the wall segment.

[0054] Next, the frame 20 is placed and fastened to the wall section 22. To this end, the frame 20 is first moved from the loose state in the assembly direction 52 toward the wall section 22. The assembly direction 52 is perpendicular to the main extension plane 44 of the wall section 22. This results in a pre-assembled state in which the frame 20 is already located on the wall section 22.

[0055] Starting from this pre-assembled state, the frame 20 is moved in a fastening direction 54 extending parallel to the main extension direction 44. In the illustrated case, the fastening direction 54 extends perpendicularly to the assembly direction 52.

[0056] The fastening elements 24, 26 are designed as hook-shaped elements. In the fastened state, the fastening elements 24, 26 engage with one another from behind. In contrast, in the pre-assembled state, this engagement from behind does not yet occur, but is instead produced by moving the frame 20 in the fastening direction 54. In the fastened state, the fastening elements 24, 26 are fixed to one another and thus prevent movement of the frame 20 relative to the wall section 22 parallel to the assembly direction 52.

[0057] The fastening system 18 further includes a locking unit 56, which is configured to prevent the fastened state from being released in the locked state and to release the fastened state in the released state. According to the present embodiment, the locking unit 56 includes a first opening 58 in the frame 20 and a second opening 60 in the wall section 22. In the fastened state, the first opening 28 is aligned with the second opening 60. The locking unit 56 also includes a locking element 62, which, in the locked state, extends through the first opening 58 and the second opening 60. The locking elements 62 are designed as screws, by means of which the frame 20 is fastened to the wall section 22. In the locked state, the locking element 62 mechanically prevents the frame 20 from moving relative to the wall section 22.

[0058] The longitudinal axis 64 of the locking element 62 extends perpendicularly to the fastening direction 54. In the locked state, the locking element 62 therefore absorbs forces acting on the frame 20 parallel to the fastening direction 54 and thus, together with the fastening elements 24, 26, prevents the frame 20 from moving relative to the wall section 22.

[0059] The locking element 62 is introduced from the front side 66 of the frame 20 through the first opening 58 and the second opening 60. In addition, in the present embodiment, the locking unit 56 comprises a further first opening 68, a further second opening 70 and a further locking element 72, which is designed similarly to the locking element 62, but is introduced into the openings 68, 70 from the top side 74 of the frame 20.

[0060] If maintenance work on the equipment item 16 is required or access to it is necessary for other reasons, the frame 20 can be removed from the wall section 22 without damage. To do this, the locking is first released by removing the locking elements 62, 72. The fastening elements 24, 26 are then released from one another by moving the frame 20 from the secured position relative to the wall section 22 counter to the fastening direction 54. This eliminates the rear engagement of the fastening elements 24, 26, and allows the frame 20 to be removed in the next step counter to the assembly direction 52.

[0061] Further embodiments of the present invention are described below. The reference numerals for these embodiments are followed by lowercase letters. The same reference numerals are used for similar or identical elements. The description will primarily focus on the differences from the first exemplary embodiment. Therefore, reference is made to the above description regarding the functions and designs of similar or identically designed elements. Furthermore, for reasons of clarity, reference numerals are provided for not all, but only for the elements mentioned.

[0062] Figure 5 A cross-sectional illustration of a fastening system 18a according to a second embodiment is shown.The fastening system 18a likewise comprises a wall segment 22a of a monument (not shown) and a frame 20a and is configured for attaching an equipment item 16a to the monument.

[0063] Fastening system 18a differs from fastening system 18 according to the above-described embodiment in the design of its locking unit 56a. Locking unit 56a has no externally visible elements. Instead, frame 20a completely covers locking unit 56a in the fastened state. Therefore, the manner in which frame 20a is fastened cannot be seen from the outside.

[0064] The locking unit 56a, similar to the above, includes openings 58a, 60a that align with one another in the secured state. The frame 20a here has a web 74a in which the first opening 58a of the two openings 58a, 60a is formed. The locked state can be achieved by pushing a locking element (not shown) through the openings 58a, 60a. This locking element can be, for example, a screw.

[0065] Figure 6 A cross-sectional view of a fastening system 18b according to a third embodiment is shown. Fastening system 18b likewise comprises a wall segment 22b of a monument (not shown) and a frame 20b, and is configured for attaching an equipment item 16b to the monument. Furthermore, fastening system 18b comprises a locking unit 56b, which is designed similarly to the locking unit according to the second embodiment.

[0066] However, the fastening system 18b differs from the two preceding exemplary embodiments in that no separate engagement elements are provided for the equipment item 16b. Instead, the equipment item 16b is held solely by the frame 20b in the receiving region 50b of the wall section 22b.

[0067] Here, the equipment item 16b can be fastened to the frame 22b, for example, glued to the frame and / or screwed to the frame. It is also possible that the equipment item 16b is loosely inserted into the receiving area 50b and is held in a fixed position in the receiving area 50b by the frame 20b in the fastened state.

[0068] In other embodiments, latching elements or the like may be provided on the equipment item 16b and / or the wall section 22b, which slightly secure the equipment item 16b after it has been inserted into the receiving area 50b, preventing it from falling out during placement of the frame 20b. However, the frame 20b still exerts the majority of the retaining force.

[0069] As mentioned above, it is also conceivable according to the present invention to not provide a recessed receiving area in the wall section. In this case, the frame can form the receiving area, and the equipment item can be placed together with the frame. The equipment item can then be fastened to the frame, for example, before the frame is attached.

[0070] Further variants of the locking unit 56 c according to the invention of a fastening system are explained below. Figure 7 A front view of the locking unit 56c is shown in the locked state. Figure 8 A front view of the locking unit 56c is shown in a released state. Reference is made to these two figures.

[0071] Locking unit 56c is part of a fastening system 18c, which, like the fastening systems 18, 18a, and 18b of the aforementioned embodiments, includes a wall segment 22c and a frame 20c and is configured for attaching an item of equipment 16c. Frame 20c has a web 74c with an opening (not shown). Locking unit 56c includes a locking element 62c, which, in the locked state, prevents movement of frame 20c parallel to a fastening direction 54c by engaging in the opening. Locking element 62c is designed as a screw or a pin.

[0072] In the illustrated case, the frame 20c comprises three webs 74c, and the locking unit 56c comprises three corresponding locking elements 62c, which for reasons of clarity are not all provided with reference numerals. A different number of elements is also possible.

[0073] The locking unit 56c comprises an actuating mechanism 75c having an actuating element 76c arranged spaced apart from the locking element 62c and a force transmission 80c mechanically coupling the actuating element 76c to the locking element 62c, wherein the locking element 62c is movable by means of the actuating element 76c.

[0074] The actuating element 76c is designed as a handle. The force transmission device 80c includes a rod 82c, via which the force applied to the actuating element 76c can be transmitted to the locking element 62c. The actuating element 76c is attached above the frame 20c and must be moved downwards to release the lock.

[0075] The locking unit 56c also includes a spring element 78c. The actuating element 76c is preloaded into the locked position by means of the spring element 78c. When the actuating element 76c is released, the locking element 62c is driven by the spring force of the spring element 78c to move through the link 74c, thereby forming a locked state. To release the locking element, the actuating element 76c must be moved against the spring force of the spring element 78c. Pressing the actuating element 76c can move the frame 20c parallel to the tightening direction 54c, as described above.

[0076] Rod 82c and the components of locking unit 56c that guide it are housed in wall section 22c and are not visible from the outside. According to this embodiment, fastening system 18c also includes a partition 84c, which is arranged adjacent to frame 20c, for example, above it. Partition 84c is fastened to wall section 22c and covers actuating element 76c. To actuate locking unit 56c, an operator can reach behind partition 84c and operate actuating element 76c.

[0077] As mentioned above, alternatively, the force transmission device that transmits the pulling force can also be selected. Here, suitable spring elements can be used equally, so that the locking state is automatically formed.

[0078] The locking unit with the actuation mechanism can also be used in the fastening system 18, 18a, 18b according to the above-described embodiments. In this case, it may be necessary to adapt the orientation of the corresponding blocking element and / or the actuation direction and / or position of the actuation element.

[0079] exist Figure 9 and Figure 10 An exemplary possibility for designing the contacts of the equipment item 16d is shown in FIG. Figure 9 A simplified side view of a portion of a fastening system 18d according to a fourth embodiment is shown before the equipment item 16d is mounted. Figure 10The simplified side view of the part of the fastening system 18d according to the fourth embodiment after the installation of the equipment item 16d is shown. The equipment item 16d has a connecting element 90d. The connecting element 90d is, for example, an electrical and / or optical plug.
