DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0053] FIG. 2 shows a cross-sectional overview of an installation system 100. The installation system 100 includes an installation arrangement 110 for connecting a first portion of an overhead luggage compartment 120 and a primary structure fastening element 130 for connecting the second portion of the overhead luggage compartment 120. The overhead luggage compartment 120 can be connected to a primary structure (not shown) of an aircraft. In general, the installation arrangement 110 comprises a first carrier element 112, a second carrier element 113 and a rod 114 (or carrier rod 114). The installation arrangement 110 can be connected to an installation rail 115 via a second carrier element 113. The primary structure fastening element generally includes a primary structure fastening component 131 and the bolt-shaped component 132 to be coupled with the primary structure fastening component 131.

[0054] As is illustrated in FIG. 2 by two arrows, the overhead luggage compartment 120 can be moved towards the installation arrangement 110, be fastened to the first carrier element 112 and then be fastened to the primary structure fastening component 131. Alternatively, the overhead luggage compartment 120 is first fastened to the primary structure fastening component 131 via bolt-shaped component 132 and is then coupled to the first carrier element 112 of the installation arrangement 110.

[0055] The overall structure may further include a cove light panel 140 that is connected to the installation arrangement 110.

[0056] FIG. 3 shows schematically an installation rail 115. The installation rail 115 may include an installation portion 200. The installation portion 200, according to an example, may have a substantially U-shaped cross-section with two arms 211 and 212 that is associated with a primary structure component 220 therebetween. The primary structure component 220 can be fastened to a primary structure (not shown) of the aircraft. The primary structure component 220 may be a single flange or web as depicted in FIG. 3. Alternatively, the primary structure component 220 or the entire installation rail 115 can have a different shape, e.g., I-shape or H-shape.

[0057] The installation rail 115 extends substantially in a longitudinal direction X of the aircraft, e.g., in a flight direction of the aircraft. Thus, the two arms 211 and 212 also extent in the longitudinal direction X of the aircraft and perpendicular thereto in the direction Z.

[0058] Furthermore, the installation rail 115 includes bores 230 or openings. The bores 230 are arranged in both arms 211, 212. A first bore 231 provided in arm 211 may align with a second bore 232 provided in arm 212, i.e., the bores 231, 232 have a common central axis. The bores 230 are spaced apart from each other in the longitudinal direction X of the installation rail 115. The distance between two adjacent bores 230 can be predefined in dependence of a pattern of overhead luggage compartments or other aircraft interior components to be mounted to the installation rail 115.

[0059] FIG. 4 shows in a top-view a plurality of overhead luggage compartments 120 (also referred to as hat racks) sharing an installation arrangement 110. One or more overhead luggage compartments 120 are arranged in a longitudinal direction X of the aircraft. According to this example, two adjacent overhead luggage compartments 120 are fastened to the primary structure of the aircraft by a single installation arrangement 110.

[0060] As illustrated in FIG. 4, each overhead luggage compartment 120 may have a further attachment position, i.e., is fastened to an installation arrangement 110, near a center of the overhead luggage compartment 120. Such center attachment may be configured to not transmit any loads in a longitudinal direction (X) of the overhead luggage compartment 120. This avoids a statically indeterminate system and allows the overhead luggage compartment 120 to move along its longitudinal direction (X) at the center attachment position. This can be achieved by providing an elongated hole at an attachment point of the overhead luggage compartment 120.

[0061] An installation arrangement 110 of a side attachment position (between two adjacent overhead luggage compartments 120) is illustrated in FIG. 5, which shows an overview of an exemplary installation arrangement 110 in cross-section (left-hand side and bottom of FIG. 5) and a side view of a first carrier element 112 thereof (right hand side of FIG. 5). Also shown in FIG. 5 is an installation rail 115 of a U-shaped form including two arms 211 and 212.

[0062] The installation arrangement 110 suitable for fastening a portion of an overhead luggage compartment 120 in an aircraft comprises a first carrier element 112 that is configured to be fastened to the overhead luggage compartment 120. Only a portion of the overhead luggage compartment 120 is illustrated in FIG. 5. This portion may correspond to a back wall of the overhead luggage compartment 120 when viewed in the direction Y (FIG. 4), e.g., a back wall of the inside when viewed through an open lid of the overhead luggage compartment 120.

[0063] The first carrier element 112 includes a main body 310 and a first barrel-shaped component 320. The main body 310 can comprise a tubular opening 311, while the first barrel-shaped component 320 can be arranged inside the tubular opening 311 of the main body 310. The main body 310 is illustrated in the form of a prism (cuboid). This provides for a flat surface for attaching the overhead luggage compartment 120. The tubular opening 311 is illustrated as a tubular void as can be derived from the dashed line in the side view illustrated on the right-hand side of FIG. 5. The tubular void 311 may, however, be open to one of the sides of the main body 310, so that the first barrel-shaped component 320 can be inserted into the main body 310.

[0064] The first barrel-shaped component 320 can comprise a first through hole 330 extending substantially perpendicular to a longitudinal axis the first barrel-shaped component 320 and, hence, substantially perpendicular to a longitudinal axis of the tubular opening 311 in the main body 310.

[0065] The first carrier element 112 further comprises fastening means 350 for fastening a portion of the overhead luggage compartment 120 to the main body 310 of the first carrier element 112. The fastening means 350 is illustrated as an internal fastener, such as a threaded bore. The overhead luggage compartment 120 is fastened to the main body 310 of the first carrier element 112 by an external fastening component 360, such as the illustrated bolt or screw 360. Alternatively, the illustrated bolt may be fixedly coupled to the main body 310 or otherwise be inserted into the main body 310. The overhead luggage compartment 120 can then be connected to this bolt by a nut 360.

[0066] The number of fastening means 350 and corresponding fastening components can vary. For instance, a single fastening arrangement (350, 360) may be enough for a transmission of forces (loads) without momentum. Two or more fastening arrangements (350, 360) also provide for transmission of a momentum from the overhead luggage compartment 120 to the main body 310.

[0067] The right-hand side of FIG. 5 shows a side view of main body 310 having four fastening means 350 arranged along a longitudinal axis (X) of the main body 310. The fastening means 350 are arranged symmetrically with respect to the longitudinal axis of rod 114. This allows connecting one overhead luggage compartment 120 to the two fastening means 350 on one side of the rod 114 and connecting another overhead luggage compartment 120 to the two fastening means 350 on the other side of the rod 114. Thus, two overhead luggage compartments 120 can be installed with one installation arrangement 110 comprising only one rod 114. The illustrated pairs of fastening means 350 can also be arranged along a different axis, e.g., along an axis (Z) perpendicular to the longitudinal axis (X) of the main body 310.

[0068] The installation arrangement 110 further comprises a second carrier element 113 connectable to the installation rail 115. The second carrier element can be a rotary joint capable of providing a degree of freedom around two axes. The illustrated second carrier element 113 includes the mounting component 410 that is connectable to the installation rail 115. For example, the mounting component 410 may be sized to fit between the two arms 211, 212 of the installation rail 115. Using respective fastening elements 460 the mounting component 410 can be connected to the installation rail 115. The fastening elements 460 may be bolts or screws inserted through respective bores 230 of the installation rail 115. The bores 230 and fastening elements 460 may provide for a rotational movement of the fastening elements 460 relative to the installation rail 115. This provides a first degree of freedom for the second carrier element 113 around an axis Y perpendicular to the longitudinal axis X of the installation rail 115.

[0069] Furthermore, the mounting component 410 of the second carrier element 113 may comprise a tubular opening 411. The tubular opening 411 is formed and arranged similarly to tubular opening 311 in the main body 310 of the first carrier element 112. The second carrier element 113 also includes a second barrel-shaped component 420. The second barrel-shaped component 420 can be arranged inside (be inserted in) the tubular opening 411 of the mounting component 410. A movement between the second barrel-shaped component 420 and the mounting component 410 is possible, so that a second degree of freedom is provided for the second carrier element 113. Thus, the second carrier element 113 is a rotary joint.

[0070] A second through hole 430 may be provided in the second barrel-shaped component 420. The second through hole 430 extends substantially perpendicular to a longitudinal axis of the second barrel-shaped component 420. Therefore, when the second barrel-shaped component 420 is inserted in the tubular opening 411 of the mounting component 410, the second through hole 430 extends substantially perpendicular to the longitudinal axis of the tubular opening 411 of the mounting component 410.

[0071] The first and second through holes 330, 340 are arranged to receive a rod 114, thereby connecting the first and second carrier elements 112, 113. For example, the first through hole 330 of the first carrier element 112 has a threaded surface and the rod 114 has a matching threaded surface on at least a portion of its outer surface. The threaded surface of the rod 114 may be provided in a center part of the rod 114 or at any other part, where the first carrier element 112 is to be attached. By a rotation of the rod 114 the engaging threads of the rod 114 and the first through hole 330 provide for a movement of the first carrier element 112 along the longitudinal axis of the rod 114.

[0072] The rod 114 can further include attachment means 510 for attaching a cove light panel 140. The attachment means 510 may be provided at an end of the rod 114 opposite to the end of the rod 114 where the second carrier element 113 is connected. The illustrated attachment means 510 are a threaded outer surface of the rod 114 (dashed line), onto which a sleeve nut 515 is threaded. The sleeve nut 515 includes elements (not illustrated) for coupling the cove light panel 140 thereto.

[0073] Furthermore, the main body 310 of the first carrier element 112 may include a third through hole 340 extending substantially perpendicular to the longitudinal axis of the tubular opening 311. The third through hole 340 is arranged at a location of the main body 310, so that the first through hole 330 of the first barrel-shaped component 320 can be aligned with the third through hole 340, when the first barrel-shaped component 320 is arranged inside the tubular opening 311 of the main body 310. Thus, the rod 114 can extend through the first through hole 330 and the third through hole 340. The third through hole 340 of the main body 310 crosses the tubular opening 311 thereof, so that the main body has two portions provided with the third through hole 340 on both sides of the tubular opening 311.

[0074] The third through hole 340 may be larger than the first through hole 330. In particular, a dimension of the third through hole 340, such as a diameter, may be larger than a dimension (diameter) of the first through hole 330. This allows a movement of the rod 114 together with the first barrel-shaped component 320 inside the main body 310 without intervening with the main body 310.

[0075] Similarly, the mounting component 410 of the second carrier element 113 can include a fourth through hole 440 extending substantially perpendicular to the longitudinal axis of the tubular opening 411 of the mounting component 410. The fourth through hole 440 is arranged at a location of the mounting component 410, so that the second through hole 430 of the second barrel-shaped component 420 can be aligned with the fourth through hole 440, when the second barrel-shaped component 420 is arranged inside the tubular opening 411 of the mounting component 410. Thus, the rod 114 can extend through the second through hole 430 and the fourth through hole 440. The fourth through hole 440 of the mounting component 410 crosses the tubular opening 411 thereof, thereby providing two parts of the mounting component 410 on both sides of the tubular opening 411 with a through hole 440.

[0076] The fourth through hole 440 in the mounting component 410 may be larger than the second through hole 430 in the second barrel-shaped component 420 of the second carrier element 113. This provides for a space for movement of the rod 114 within the mounting component 410 of the second carrier element 113 due to a movement of the second barrel-shaped component 420 in the mounting component 410.

[0077] FIG. 6 shows a cross-section and side view of the second carrier element 113 connected to the installation rail 115. Furthermore, the rod 114 comprises fastening means 520 for coupling the rod with the second barrel-shaped component 420. The fastening means 520 may be a threaded bore in the side face of the rod 114, into which a screw 525 is threaded. The screw 525 is provided with a head of greater size than the second through hole 430 in the second barrel-shaped component 420. This provides for a coupling of the rod 114 and the second barrel-shaped component 420 in the longitudinal direction of the rod 114, but still allows a rotation of the rod 114 within the second through hole 430.

[0078] Alternatively, as shown in FIG. 5, the rod 114 may be provided with a threaded outer surface at its end inserted into the second barrel-shaped component 420. The second through hole 430 may then be provided with matching threaded inner surface, so that the rod 114 can be fixedly screwed into the second through hole 430. This arrangement provides for a fastening in the longitudinal direction of the rod 114, still allows a rotation of the rod 114 and also allows an adjustment of the extent of insertion of the rod into the second barrel-shaped component 420.

[0079] Again with respect to FIG. 6, and, in particular, the side view of the installation rail 115 on the right-hand side, the mounting component 410 may extend in a longitudinal direction of the installation rail 115 over more than one bore 230. In this case, the mounting component 410 could be fastened to the installation rail 115 with more than one fastening element 460. This would provide for a better load transmission into the installation rail 115. However, a rotation of the second carrier element 113 around the perpendicular axis Y of the installation rail 115 would be prevented.

[0080] FIG. 7 shows in a top-view a plurality of overhead luggage compartments 120 (also referred to as hat racks) with individual installation arrangements 110. As can be derived from a comparison of FIGS. 4 and 7 the overhead luggage compartments 120 are installed independent of each other, since each overhead luggage compartment 120 is provided with its own installation arrangement(s) 110.

[0081] Correspondingly, as illustrated in FIG. 8, the installation arrangement 110 includes a first carrier element 112 with only one fastening means 350 for fastening one overhead luggage compartment 120. FIG. 8 further illustrates fastening means 350 of the first carrier element 112 in the form of (threaded) bolt 355, onto which the overhead luggage compartment 120 can be moved with a respective hole in the overhead luggage compartment 120. Both elements are then affixed to each other with a nut 360. This allows the reduction of the lever arm of the overhead luggage compartment 120 with respect to the longitudinal axis of the rod 114. As can be derived from a comparison of FIGS. 5 and 8, the solution provided in FIG. 8 has a smaller lever arm than the solution provided in FIG. 5, since the latter requires an interior fastening means 350 which shall not intervene with the tubular opening 311.

[0082] FIG. 9 shows a three-dimensional view of an exemplary installation arrangement 110, where the first barrel-shaped component 320 has been omitted to allow a view inside the tubular opening 311. The rod 114 is provided with a portion having a thread 371 on its outer surface. This thread 371 is configured to engage with a corresponding thread of the first barrel-shaped component 320 (not shown in FIG. 9).

[0083] In addition, FIG. 9 depicts two fastening means 350 of the first carrier element 112 in the form of two (threaded) bolts 355, onto which the overhead luggage compartment 120 (not shown in FIG. 9) can be moved employing respective holes or openings in the overhead luggage compartment 120. Both elements can then be affixed to each other with a nut 360 (not shown in FIG. 9). The illustrated arrangement of two bolts 355 provides for a load transmission including momentums from the overhead luggage compartment 120 to the first carrier element 112.

[0084] Furthermore, the rod 114 comprises a ridged section 372 at an upper end of the rod 114. This ridged section 372 provides ridged segments on two sides of the rod 114 interrupted by two plain surface segments. This provides for inserting the rod into the second barrel-shaped component 420 (illustrated as a cap-like component) which has corresponding ridged and plain segments at an angle of about 90°. When turning the rod 114 by 90°, the ridges of the rod 114 and the second barrel-shaped component 420 become engaged and the rod 114 can be connected to the second barrel-shaped component 420 at the insertion level before turning the rod 114.

[0085] FIG. 10 shows a cross-section of an exemplary variant of an installation arrangement 110. Here, the first carrier element 112 is integrated into the overhead luggage compartment 120. For instance, the overhead luggage compartment 120 may be provided with a tubular element 122. This tubular element 122 may have a threaded interior surface, into which the rod 114 can be screw by engaging matching threads (not shown) of the rod 114. Alternatively, the tubular element 122 and the rod 114 may be provided with ridged and plain segments as explained with respect to the second carrier element 113 in FIG. 9.

[0086] The cove light panel 140 can then be attached to the tubular element 122 of the overhead luggage compartment 120 by a corresponding fastening means 530. Alternatively, the tubular element 122 has an open end at its bottom, so that the rod 114 can extend to the outside of the overhead luggage compartment 120 at which the cove light panel 140 can be attached as described with respect to FIG. 5.

[0087] FIG. 11 shows a cross-section of an exemplary further variant of an installation arrangement 110. In this exemplary variant, the rod 114 is split and comprises a first rod 610. The first rod 610 can be coupled with the second carrier elements 113 in any of the above described manners. The rod 114 further comprises a second rod 615 that is connected to the first rod 610 by a sleeve nut 620. The longitudinal extent of the sleeve nut 620 provides for a secure connection of the first rod 610 with the second rod 615, while also allowing the installation of the first rod 610 and the second rod 615 in a spaced apart manner

[0088] The first carrier element 112 is illustrated as being mounted to the second rod 615. This variant allows installation of the second carrier element 113 in the installation rail 115 and the attachment of the first rod 610 at the second carrier element 113. The overhead luggage compartment (not shown in FIG. 11) and the cove light panel 140 can then be mounted to the first rod to 610 via the second rod 615 and the sleeve nut 620.

[0089] It is to be understood, that the first carrier element 112 may alternatively be mounted to the first rod 610 above the sleeve nut 620. The cove light panel 140 can then be attached to the sleeve nut 620 at a later stage with the second rod 615.

[0090] In addition, FIG. 11 also illustrates a further variant of attaching the cove light panel 140 to rod 114 compared to the attachment illustrated in, for example, FIG. 5. In FIG. 11 the cove light panel 140 is provided with a through hole 141, through which the rod 114 or the second rod 615 may run. The cove light panel 140 is then attached to the rod 114, 615 with a nut 142. For instance, the nut 142 may be threaded onto a threaded outer surface of the rod 114, 615. Alternatively, the outer surface of the rod 114, 615 may be plain and the cove light panel 140 is attached to the rod 114, 615 by a nut 142 screwed onto a bushing 143. The bushing 143 may be provided with a flange, so that the bushing is squeezed into the through hole 141 of the cove light panel 140 and onto the rod 114, 615.

[0091] FIG. 12 shows a cross-section of a second carrier element 113 including a shock absorbing component 710. The shock absorbing component 710 can be arranged in the tubular opening 411 of the mounting component 410. The shock absorbing component 710 can further be configured to receive the second barrel-shaped component 420. Thus, the shock absorbing component 710 may be formed as a cylinder that is sized to fit between the mounting component 410 and the second barrel-shaped component 420, the latter of which is also sized smaller than compared to the variant without shock absorbing component 710. Thus, any vibrations or other forces carried by the primary structure of the aircraft and introduced into the installation rail 115 may be absorbed or at least reduced by shock absorbing component 710. The interior components, such as the overhead luggage compartment 120 and/or cove light panel 140, do not receive the same vibrations or forces from the primary structure. This reduces noise within the aircraft and also protects the interior components.

[0092] FIG. 13 shows a cross-section of an installation arrangement 110 having a variant of a second carrier element 113. In this variant, the second carrier element includes a holding portion 810 connectable to the installation rail 115. The second carrier element 113 further comprises an arcuate portion 820 forming a void 830 with the holding portion 810. The arcuate portion 820 includes a fifth through hole 825 to receive the rod 114 including a predetermined clearance. The size (for example diameter) of the fifth through hole 825 is larger than the size (for example diameter) of the rod 114 providing the rod 114 with a certain clearance for movement.

[0093] The second carrier element 113 also includes an arcuate disc 840 provided in the void 830. The arcuate disc 840 is coupled to the rod 114 so that the arcuate disc 840 bears any load introduced by the rod 114 on the surface of the arcuate portion 820 facing the void 830. The void 830 is also dimensioned larger than the arcuate disc 840 to provide the arcuate disc 840 with enough space for movement. Thus, the second carrier element 113 also provides a rotary joint having at least two degrees of freedom for the rod 114.

[0094] In addition, an arcuate element 850 may be provided on the installation rail 115. The arcuate element 850 can be arranged to provide a second bearing surface for the arcuate disc 840 on a side opposite to the arcuate portion 820 of the second carrier element 113. The arcuate element 850 may be of an elastic material so that the arcuate disc is less likely to be pushed towards the installation rail 115. Shock absorption is also achieved by such elastic arcuate element 850.

[0095] It is to be understood that the examples and variants of certain components and elements of the installation arrangement(s) illustrated in one of the Figures and described above can be combined with examples and variants illustrated in another Figure.
