Fastening system for fastening a cabin fitting element to a support structure of an aircraft
View Patent ↗A fastening system for fastening a cabin fitting element with at least one electrical installation on a support structure of an aircraft. During installation into the support structure, the cabin fitting element is fixed in succession by at least one loose bearing in at least one degree of translational freedom and then by at least one fixed bearing in the at least one further degree of translational freedom. In order to ensure an improved installation and dismantling of cabin covering panels with electrical installation and to reduce the weight due to the components and also the installation space which is required, according to the disclosed embodiments a contact device with a bush arrangement and a plug arrangement is integrated in the at least one loose bearing and/or the at least one fixed bearing, by which an electrical connection is produced between the support structure and the electrical installation of the cabin fitting element on fixing at least of one degree of translational freedom.
1. A fastening system for fastening a cabin fitting element with at least one electrical installation on a support structure of an aircraft,
in which the cabin fitting element on installation into the support structure is fixed in succession by at least one loose bearing in at least one degree of translational freedom and then by at least one fixed bearing in the at least one further degree of translational freedom,
wherein
a contact device with a bush arrangement and a plug arrangement is integrated in the at least one loose bearing, by which an electrical connection is produced between the support structure and the electrical installation of the cabin fitting element during the fixing of at least of one degree of translational freedom and the bush arrangement and/or the plug arrangement is displaceable in the insertion direction between a first and a second stop in the loose bearing.
2. The fastening system according to claim 1 , further comprising that the bush arrangement and/or the plug arrangement is rotatable about at least one axis, standing perpendicular to the insertion direction, in the bearing.
3. The fastening system according to claim 1 , further comprising that the bush arrangement and/or the plug arrangement is displaceable in the insertion direction between a first and a second stop in the bearing.
4. The fastening system according to claim 2 , further comprising that the bush arrangement and the plug arrangement are automatically aligned to each other by a conically tapering guide opening and a complementary acutely tapering guide pin on fixing a degree of translational freedom.
5. The fastening device according to claim 2 , further comprising that the bush arrangement and the plug arrangement are automatically aligned to each other by a complementary, substantially conically tapering outer shape on fixing a degree of translational freedom.
6. The fastening system according to claim 1 , wherein the fixed bearing comprises a connecting pin and a passage opening to which respectively a second bush arrangement and a second plug arrangement is symmetrically arranged, so that the second bush arrangement and the second plug arrangement produce an electrical connection when the fixed bearing is assembled.
7. The fastening system according to claim 6 , further comprising that the second bush arrangement and/or the second plug arrangement is rotatable about its axis of symmetry and alignment aids are provided, by which the second bush arrangement and the second plug arrangement are automatically aligned to each other when bearing halves of the fixed bearing are being brought up to each other.
8. The fastening system according to claim 1 , further comprising that a visible and/or acoustic signal is generated when the bush arrangement and the plug arrangement have been connected with each other.
9. The fastening system according to claim 1 , further comprising that a mechanical detent mechanism is provided for the permanent connection of the bush arrangement and the plug arrangement.
10. The fastening system according to claim 1 , further comprising that a magnetic closure system is provided for the permanent connection of the bush arrangement and the plug arrangement.
