Abstract
Description
[0001] The present invention relates to a cabin monument for an aircraft.
[0002] In aircraft, the interior space enclosed by the fuselage is typically spatially subdivided. So-called cabin monuments are used to create enclosed spaces within the interior. These cabin monuments primarily serve to accommodate sanitary facilities such as toilets, sinks, and the like, as well as storage areas.
[0003] Cabin monuments typically have several side walls enclosing an interior space, made of a composite material with a honeycomb structure to ensure high side wall rigidity. The side walls are generally arranged end-to-end with abutment and are directly screwed or glued together at the end faces. Due to the honeycomb structure, inserts are usually provided to accommodate the screws in the honeycomb structure to screw the side walls together. During gluing, the honeycomb structure is usually filled with a filler material at the end faces to create an adhesive surface. Fittings are often used to stiffen the side walls. Cabin monuments are shown, among others, in US 6 101 766 A, US 5 150 863 A, and US 2009 / 0 278 429 A1.
[0004] It is an object of the present invention to provide a cabin monument improved in terms of rigidity and mountability.
[0005] This object is achieved according to the invention by a cabin monument for an aircraft, which has a frame and a plurality of side walls. The frame has a base frame forming a perimeter of a base area of the cabin monument and a frame structure connected to the base frame. The frame structure has a plurality of superstructure struts extending from the base frame. The number of side walls of the cabin monument corresponds to the number of superstructure struts, with the side walls each extending between two superstructure struts following one another along the perimeter and being attached to these struts.
[0006] According to the invention, a cabin monument is therefore specified with a frame defining a spatial extent of the cabin monument and with side walls attached to it. The frame has, in particular, a base frame that defines a base area of the cabin monument. A frame structure, which has a plurality of, in particular, elongated structural struts or longitudinal members, is mechanically connected to or attached to the base frame. The base frame and the frame structure together define an interior of the cabin monument. The structural struts are arranged along the base frame, with a side wall extending between each two consecutive structural struts or longitudinal members and being attached to these. The frame thus forms a type of skeleton or supporting structure for the cabin monument. The frame thus significantly improves the mechanical rigidity of the cabin monument.
[0007] By attaching the side walls to the frame struts, the mechanical load acting on the cabin monument is efficiently distributed between the frame and the side walls. This significantly reduces the stress on the individual components of the cabin. This allows for a reduction in wall thickness, which simultaneously keeps the weight of the cabin monument low. Attaching the side walls to the frame struts also offers the advantage of providing a reliable fastening structure for attaching the side walls. This eliminates the need for any machining of the side walls that would otherwise be required.
[0008] Advantageous embodiments and further developments arise from the subclaims which refer back to the independent claims in conjunction with the description.
[0009] The base frame can, in particular, be designed as a flat frame. Accordingly, the base frame extends in such a way that it forms a continuous plane.
[0010] Furthermore, the base frame can be constructed from several frame struts attached to one another. This allows for space-saving storage and transport of the base frame prior to assembly. Furthermore, a modular design of the cabin monument can be realized in this way.
[0011] According to an advantageous development, the base frame is designed as a closed or continuously circumferential frame. This ensures high mechanical rigidity of the base frame.
[0012] According to the invention, the side walls are each designed as sandwich panels with a core having a hollow structure. The side walls therefore have, in particular, an inner panel, an outer panel, and a core arranged between mutually facing surfaces of the panels. The core forms cavities in the space extending between the surfaces of the panels. This can be achieved, in particular, by a honeycomb-like, channel-like, or similar structure of the core. It is also conceivable for the core to be made of a material forming a hollow structure, for example a foam material or the like. The sandwich-like structure with a core forming a hollow structure achieves a relatively high rigidity of the side walls in relation to their weight.Because the side panels are attached to the frame structure, such sandwich panels can be installed as side panels without any special prior processing. The design of the side panels as sandwich panels, combined with their attachment to the frame structure, thus improves the mechanical stability of the cabin monument while maintaining low weight and simplifying its assembly.
[0013] According to a further advantageous development of the cabin monument, the base frame forms the perimeter of the base area of the cabin monument with at least two corners, and one of the structural struts of the frame structure extends from each of the corners of the base frame. In particular, the base frame has a discontinuous, bending profile along its perimeter at least in two places. This results in a space-saving construction of the cabin monument, especially when the base frame extends straight between two consecutive corners.
[0014] In particular, it can be provided that the base frame forms the perimeter of the base area of the cabin monument with four corners. This allows for space-saving adaptation of the base area of the cabin monument to a variety of possible installation scenarios. The design of the base frame with four corners particularly encompasses a rectangular base area of the cabin monument. In this case, the base frame extends straight between two consecutive corners. This facilitates both the assembly of the cabin monument itself and the installation of add-on components to the cabin monument.
[0015] According to the invention, the structural struts provided at two consecutive corners delimiting a rear side of the base frame are each arcuate. Furthermore, these structural struts are each connected or coupled to the structural struts provided on a front side of the base frame, with the front side being opposite the rear side. Accordingly, the frame structure forms an at least partially arcuate spanning of the base frame between opposite sides thereof. The rear structural struts are coupled to the front structural struts, in particular in the region of the end sections of the front structural struts located opposite the base frame. The front and rear structural struts can be fastened directly to one another and thus directly connected to one another.Alternatively, a cross brace, described in more detail below, extending between the front superstructure struts can be provided, to which the rear, arched superstructure struts are attached. In this way, the arched superstructure struts are indirectly connected to the front superstructure struts via the cross brace. The arched design of the superstructure struts provided at the rear corners of the base frame allows for a particularly space-saving arrangement of the cabin monument in a cylindrical aircraft fuselage. Furthermore, the mechanical rigidity of the frame is significantly increased by the coupling of the front and rear superstructure struts.
[0016] The struts provided on the front can, in particular, be located at corners. In this case, the front struts are arranged at corners formed by the base frame. With a base frame design with four corners, two corners define the rear of the base frame, and two corners opposite these corners define the front of the base frame. This creates a space-saving frame with high mechanical strength, particularly with a rectangular base frame design.
[0017] According to a further embodiment, the frame structure additionally comprises at least one cross brace, which extends between two structural braces. In particular, the at least one cross brace extends between two consecutive structural braces. This further increases the mechanical strength of the frame. Furthermore, the cross braces form additional fastening structures for the side walls.
[0018] As already described above, the arched body struts, if provided, can be connected to or attached to a cross strut extending between the body struts provided on the front of the base frame.
[0019] According to a further advantageous development of the cabin monument, the superstructure struts and / or the base frame are designed as hollow profiles. The superstructure struts therefore have a hollow cross-sectional shape. Alternatively or additionally, the base frame, and possibly the frame struts forming it, can also be designed with a hollow cross-sectional shape. Hollow profiles offer the advantage of being lightweight and highly rigid.
[0020] In particular, it can be provided that the structural struts and / or the base frame are designed with a triangular or trapezoidal cross-section. The leg surfaces of the triangular or trapezoidal profiles advantageously provide stable mounting surfaces, particularly when the structural struts are arranged at the corners of the base frame.
[0021] The structural struts and / or the base frame can, in particular, comprise a metal material, preferably an aluminum or titanium material, and in particular be formed from such a material. Metals, especially aluminum- or titanium-based ones, exhibit high mechanical strength relative to their weight.
[0022] According to an advantageous embodiment of the cabin monument, the side walls are each connected to the body struts by a connecting means. Connecting devices such as screws, rivets, pins, or the like can be provided as connecting means. Alternatively, an adhesive can also be provided as a connecting means. In particular, several screws penetrating the side walls and penetrating the respective body strut can be provided along the longitudinal extent of each of the body struts. Screwing the side walls to the body struts advantageously creates a reliable, simple, and quick-to-install attachment of the side walls to the body struts. Furthermore, the screw connection provides a detachable attachment, so that the cabin monument can advantageously be dismantled without causing damage.
[0023] According to an advantageous development, the side walls abut each other at the structural struts in such a way that they form a miter. Accordingly, the side walls abut each other at facing end faces, with the end faces being inclined relative to the main surfaces of the side walls. This design is particularly advantageous when the structural struts are arranged at corners of the base frame, as it avoids open end faces of the side walls. This eliminates the need for panels or, if necessary, filling the hollow structure of the core.
[0024] According to the invention, the body struts each have a support part and a clamping part, and the side walls ending at the respective body strut are clamped between the support part and the clamping part. Thus, the side walls are clamped between two mutually facing clamping surfaces of the respective body strut and thereby secured to it. This ensures a reliable and particularly easy-to-install attachment of the side walls. In particular, no additional processing of the side walls is required.
[0025] The support part is designed in particular as an elongated component, preferably as a component defining the overall length of the body strut. The clamping part is connected to the support part. This can be achieved in particular by the support part and the clamping part being designed as separate components that are detachably connected to one another, in particular by being screwed together. This offers the advantage that the body struts can be used for side walls with different wall thicknesses. This expands the possible uses of the cabin monument. Alternatively, the clamping part and the support part can also be designed as a single piece. In this case, it is particularly conceivable for the support part and the clamping part, in at least one of the body struts, to be designed as separate components that are detachably connected to one another. The single-piece design advantageously reduces the number of components of the cabin monument.Furthermore, no additional step is required during the assembly of the cabin monument to connect the support part and the clamping part.
[0026] According to a further advantageous development of the cabin monument, the clamping part extends over at least 50 percent of the longitudinal extent of the support part. This achieves a flat clamping of the side wall between the support and clamping parts, thereby improving the mechanical load-bearing capacity of the connection.
[0027] In particular, it can be provided that the clamping part extends over at least 90 percent of the longitudinal extent of the support part, and preferably the clamping part and the support part have an identical longitudinal extent. This results in clamping essentially over the entire length of the side wall. This creates a visually appealing connection between the side wall and the body strut without requiring any additional processing of the side wall.
[0028] To improve the mechanical strength of the connection between the body strut and the side wall, an adhesive layer can be provided on at least one of the clamping surfaces formed on the clamping part and the support part. Alternatively or additionally, nubs or the like can be provided on the clamping surfaces, which press into the side walls when clamped.
[0029] According to a further advantageous embodiment, the support part is designed as a hollow profile. Hollow profiles offer the advantage of being lightweight yet highly rigid.
[0030] According to the invention, the support part is designed with a trapezoidal cross-section. The flank surfaces of the trapezoidal profiles advantageously provide large clamping surfaces, particularly when the structural struts are arranged at the corners of the base frame. The clamping part is preferably designed as a corner profile, for example, with an L-shaped or V-shaped cross-section.
[0031] The support part and / or the clamping part of the structural struts can, in particular, comprise a metal material, preferably an aluminum or titanium material, and in particular be formed from such a material. Metals, especially aluminum- or titanium-based ones, have high mechanical strength relative to their weight.
[0032] According to a further aspect of the present invention, an aircraft is provided with a fuselage, an interior floor extending into an interior space of the aircraft defined by the fuselage, and a cabin monument according to one of the above-described embodiments. The base frame of the cabin monument is arranged on the interior floor.
[0033] A further aspect of the present invention relates to the use of a cabin monument according to one of the above-described embodiments as an enclosure for a lavatory in an aircraft. Since the cabin monument has a particularly high degree of rigidity and inherent stability due to the frame structure, a relatively large cabin monument can advantageously be provided. This results in considerable freedom of movement for users within the lavatory.
[0034] In this context, a corner can generally be understood as a discontinuous course of a structure.
[0035] Herein, the terms "one-piece", "one-piece", "integral" or "in one piece" are generally understood to mean that these components are present as a single part forming a material unit and, in particular, are manufactured as such, wherein one component cannot be separated from the other without disrupting the material cohesion of the other.
[0036] With regard to directions and axes, in particular directions and axes relating to the course of physical structures, the course of an axis, a direction or a structure “along” another axis, direction or structure is understood to mean that these, in particular the tangents resulting at a respective point of the structures, each run at an angle of less than 45 degrees, preferably less than 30 degrees and particularly preferably parallel to one another.
[0037] With regard to directions and axes, in particular directions and axes relating to the course of physical structures, the term "transverse" to another axis, direction or structure is understood to mean that these, in particular the tangents resulting at a respective point of the structures, each run at an angle of greater than or equal to 45 degrees, preferably greater than or equal to 60 degrees and particularly preferably perpendicular to one another.
[0038] The invention is explained below with reference to the figures of the drawings. The figures show: Fig. 1 is an exploded perspective view of a cabin monument according to an embodiment of the present invention; Fig. 2 a broken detail view of a fastening of side walls of the Fig. 1 shown cabin monument on a body strut as a broken-away view; Fig. 3 is an exploded perspective view of a cabin monument according to another embodiment of the present invention; Fig. 4 a fragmentary detailed view of a fastening of side walls of the Fig. 3 shown cabin monument on a body strut as a broken-away view; Fig. 5 a sectional view of the fastening of the side walls of the Fig. 3 shown cabin monument on the body strut; and Fig. 6 an aircraft according to an embodiment of the present invention, wherein a fuselage of the aircraft is shown in a sectional view.
[0039] In the figures, the same reference symbols denote identical or functionally identical components, unless otherwise stated.
[0040] The Fig. 1 and Fig. 3 each show a cabin monument 1 for an aircraft 100. The cabin monument 1 has a frame 2 and several side walls 30A, 30B, 30C, 30D. As the Fig. 1 and Fig. 3 respectively, the frame 2 comprises a base frame 10 and a frame structure 20. The base frame 10 forms a circumference U of a base area 3 of the cabin monument 1. In the Fig. 1 and Fig. 3, the base frame 10 forms, for example, the circumference U of a rectangular base area 3 of the cabin monument 1. In Fig. 1, due to the perspective of the view, only three of the four corners 3A, 3B, 3C, 3D of the base area 3 are visible. As the Fig. 1 and Fig. 3 further show, the base frame 10 can in particular have a plurality of interconnected frame struts 10A, 10B, 10C, 10D. In the Fig. 1 and Fig. 3, the base frame 10 is shown as an example as a closed frame that encloses the base area 3.
[0041] As in the Fig. 1 and Fig. As further shown in Figure 3, the frame structure 20 and the base frame 10 are connected or fastened to each other and together form an interior space 4 of the cabin monument 1. In particular, the frame structure 2 thus defines the spatial extent or the spatial shape of the cabin monument 1.
[0042] As in the Fig. 1 and Fig. 3, the frame structure 20 comprises a plurality of structural struts 20A, 20B, 20C, 20D extending from the base frame 10, as well as optionally provided cross struts 23. These are each connected to the base frame 10 by a first end section 24, for example, screwed, riveted, welded, glued, or the like. As shown particularly in Fig. 1, it can be provided in particular that the frame struts 10A, 10B, 10C, 10D of the base frame 10 each extend between two successively arranged structural struts 20A, 20B, 20C, 20D of the frame structure 20. The structural struts 20A, 20B, 20C, 20D are accordingly provided at the corners 3A, 3B, 3C, 3D or form them.
[0043] As in the Fig. 1 and Fig. 3, the body frame 20 has an arcuate rear body strut 20B, 20C at each of two consecutive corners 3B, 3C. The corners 3B, 3C, at which the arcuate body struts 20B, 20C are provided, together define a rear side 11 of the base frame. The arcuate body struts 20B, 20C are each connected to the base frame by their first end portion 24. The arcuate rear body struts 20B, 20C are each connected to the body struts 20A, 20D provided on a front side 12 of the base frame 10. As the Fig. 1 and Fig. 3, the front side 12 is arranged opposite the rear side 11. In particular, the front side 12 is delimited by the corners 3A, 3D. The arcuate structural struts 20B, 20C are connected to the structural struts 20A, 20D arranged on the front side 12. In particular, the arcuate structural struts 20B, 20C can each be connected to a second end section 25 of the front-side structural struts 20A, 20D by a second end section 25 located opposite the first end section 24 with respect to their longitudinal extent. As shown in the Fig. 1 and Fig. 3, the front structural struts 20A, 20D are preferably designed as straight spars.
[0044] As in the Fig. 1 and Fig. 3, the optional cross braces 23 extend between two successive structural braces 20A, 20B, 20C, 20D along the base frame 10. In Fig. 1, two cross braces 23 extending between the front body brace 20A and the rear body brace 20B, as well as two cross braces 23 extending between the curved rear body braces 20B, 20C, are shown as examples. In Fig. 3, by way of example, only one cross strut 23 is provided extending between the front body struts 20A, 20D, in particular between their end sections 25.
[0045] The Fig. 1 and Fig. 3 further show schematically that the number of side walls 30A, 30B, 30C, 30D corresponds to the number of structural struts 20A, 20B, 20C, 20D. Accordingly, in the Fig. 1 and Fig. 3, four side walls 30A, 30B, 30C, 30D are provided for each of the cabin monuments 1, each illustrated schematically and by way of example. The side walls 30A, 30B, 30C, 30D each extend between two superstructure struts 20A, 20B, 20C, 20D that follow one another along the circumference U or along the base frame 10, and are attached to them. As shown in Fig. As shown in Figure 3, at least one of the side walls 30A, 30B, 30C, 30D can have a recess 32. The recess 32 forms an access opening to the interior 4 of the cabin monument 1 and can be closed or opened, for example, by a door (not shown) mountable on the cabin monument 1. The side walls 30A, 30B, 30C, 30D are each designed as plate-shaped, flat components.
[0046] As in the Fig. 2, Fig. 4 and Fig. 5, the side walls 30A, 30B, 30C, 30D can each be designed in particular as sandwich panels with a core 31 having a hollow structure. Fig. 2, Fig. 4 and Fig. 5, the core 31 is shown as a honeycomb structure. The core 31 can be arranged in particular between an inner cover plate 33 and an outer cover plate 34, as shown schematically in the Fig. 2, Fig. 4 and Fig. 5 is shown.
[0047] In Fig. 2 is a schematic perspective view of a broken sectional view of the cabin monument 1, for example of the one shown in Fig. 1 shown cabin monument 1, in the area of a superstructure strut 20A, 20B, 20C, 20D. As shown in Fig. 2, the side walls 30A, 30B, 30C, 30D can each be fastened to the body struts 20A, 20B, 20C, 20D by means of screws 40. The screws 40 extend through the side walls 30A, 30B, 30C, 30D and are preferably screwed with an end region into respective threaded recesses 26 formed on the body struts 20A, 20B, 20C, 20D.
[0048] As in Fig. 2, the structural struts 20A, 20B, 20C, 20D can be designed in particular as hollow profiles with a triangular cross-section. Fig. 2 further shows, the side walls 30A, 30B, 30C, 30D abut each other at the superstructure struts 20A, 20B, 20C, 20D with angled end faces, thus in the form of a miter. As shown in Fig. 2, this simply prevents the core 31 from being visible.
[0049] As an alternative to screwing the side walls 30A, 30B, 30C, 30D to the body struts 20A, 20B, 20C, 20D, it can also be provided that the side walls 30A, 30B, 30C, 30D are clamped to the body struts 20A, 20B, 20C, 20D for fastening, as shown schematically in the Fig. 3 to 5. In this case, the structural struts 20A, 20B, 20C, 20D each have a support part 21 and a clamping part 22. As shown particularly in Fig. 3, the support part 21 is designed as an elongated, strut-like component. Preferably, the clamping part 22 is also designed as an elongated, strut-like component. Preferably, the support part 21 and the clamping part 22 each have approximately the same length or longitudinal extent, as shown, for example, in Fig. 3. In particular, it can be provided that the clamping part 22 extends over at least 50 percent of the longitudinal extent of the support part 21.
[0050] As particularly in Fig. As shown in Figure 5, a support part clamping surface 21a, 21b is formed on the support part 21 and a clamping part clamping surface 22a, 22b is formed on the clamping part 22, wherein the support part clamping surface 21a, 21 and the clamping part clamping surface 22a, 22b are oriented facing each other. The side walls 30A, 30B, 30C, 30D, each ending at a body strut 20A, 20B, 20C, 20D, are each clamped between the support part clamping surface 21a, 21b and the clamping part clamping surface 22a, 22b and are thereby fastened to the respective body strut 20A, 20B, 20C, 20D. As shown in Fig. As shown by way of example in Figure 5, the support part clamping surface 21a, 21b can each be formed by a first partial clamping surface 21a and a second partial clamping surface 21b. Furthermore, the clamping part clamping surface 22a, 22b can each be formed by a first partial clamping surface 22a and a second partial clamping surface 22b. Here, the first partial clamping surface 21a of the support part 21 faces the first partial clamping surface 22a of the clamping part 22. Furthermore, the second partial clamping surface 21b of the support part 21 faces the second partial clamping surface 22b of the clamping part 22. To fasten the side walls 30A, 30B, 30C, 30D, an end section of a first side wall ending at the respective body strut 20A, 20B, 20C, 20D is clamped between the first partial clamping surfaces 21a, 22a and an end section of another first side wall ending at the body strut 20A, 20B, 20C, 20D is clamped between the second partial clamping surfaces 21b, 22b. According to the exemplary illustration in Fig. 5, the end portion of the side wall 30A is clamped between the first partial clamping surfaces 21a, 22a and the end portion of the side wall 30B is clamped between the second partial clamping surfaces 21b, 22b.
[0051] As particularly in Fig. As shown in Figure 5, the support part 21 can be designed, in particular, as a hollow profile with a trapezoidal cross-section. The partial clamping surfaces 21a, 21b of the support part 21 are provided on the sides of the hollow profile, which connect the sides of the trapezoidal cross-section that run along one another, in particular parallel to one another. Furthermore, elevations or knobs 27 can be provided on the support part clamping surface 21a, 21b, which are pressed into the cross-section of the side wall 30A, 30B, 30C, 30D when clamped.
[0052] The Fig. 4 and Fig. 5 further show an exemplary design of the clamping part 22. In general, the clamping part 22 has the clamping part clamping surface 22a, 22b, wherein the clamping part clamping surface 22a, 22b is preferably designed to be complementary to the support part clamping surface 21a, 21b. In particular, the clamping part 22, as shown in the Fig. 4 and Fig. 5 is shown as an example, as a substantially L-shaped, elongated angle profile with a first tab 51 and a second tab 52 extending transversely thereto. The first and second tabs 51, 52 of the clamping part 22 are connected to one another in a connecting region 53, wherein the connecting region 53 can in particular each have an extension extending at an angle to the tabs 51, 52, as in the Fig. 4 and Fig. 5 is shown by way of example. The first partial clamping surface 22a of the clamping part 22 is formed on the first tab 51, and the second partial clamping surface 22b of the clamping part 22 is formed on the second tab 52. The clamping part 22 furthermore has a first rib 54 and a second rib 55. The first rib 54 is provided on the first tab 51, wherein the first rib 54 delimits the first partial clamping surface 22a and protrudes therefrom. The second rib 55 is provided on the second tab 52, wherein the second rib 55 delimits the second partial clamping surface 22b and protrudes therefrom. A third rib 56 can also be provided in the connecting region 53 and extends on the side of the partial clamping surfaces 22a, 22b. Alternatively or in addition to the elevations or knobs 27 optionally provided on the support part clamping surface 21a, 21b, elevations or knobs (not shown) can also be provided on the clamping part clamping surface 22a, 22b.
[0053] As in the Fig. 4 and Fig. 5, the support part 21 and the clamping part 22 can each be designed as separate components. Fig. 4 and Fig. 5 shows an example of fastening the clamping part 22 to the support part 21 by means of screws 45. The screws 45 extend, as shown in Fig. 5, through the clamping part 22 and are preferably screwed with an end region into respective threaded recesses 26 formed on the support part 21. As in Fig. 5, the screw 45 extends particularly in the region of the connecting region 53 and preferably through the third rib 56. In Fig. 3, the screws 45 are shown only schematically as circles.
[0054] Fig. 6 shows, by way of example, an aircraft 100 with a fuselage 101, wherein the fuselage 101 is shown in a sectional view, an interior floor 103, and the cabin monument 1. The fuselage 101 defines an interior 102 of the aircraft 100, into which the interior floor 103 extends. For example, the interior floor 103 forms a partial interior 104 with the fuselage 101. The partial interior 104 can, for example, comprise a passenger cabin of the aircraft 100. The cabin monument 1 is arranged on the interior floor 103. In particular, the base frame 10 of the cabin monument 1 is arranged on the interior floor 103. The rear side 11 of the base frame 1 is preferably arranged adjacent to the fuselage 101. As in Fig.As can be seen in Figure 6, the curved design of the rear superstructure struts 20B, 20D ensures excellent space utilization of the interior 102 or the partial interior 104. The cabin monument 1 preferably forms an enclosure for a toilet compartment in the aircraft 100.
