Description

The invention relates to a device for fastening an in-fill panel element to a plane panel element of a covering for an aircraft, the in-fill panel element and the panel element being releasably interconnected at longitudinal sides facing each other.

From DE 197 30 269 A1 and the not prepublished German Patent Application 100 63 035, respectively, a device for fastening a panel element to a stationary bearing profile for a covering of an aircraft is known, wherein fastening elements are arranged at one longitudinal side of the panel element. Usually, such panel elements that may comprise air shower segments or reading light segments are spaced from or arranged adjacent to each other along the aircraft interior. Moreover, there are preferably narrow in-fill panel elements having no fastening elements of their own for being fastened to the stationary bearing profile. Such in-fill panel elements serve as intermediate elements for covering a clearance that has been left vacantly between panel elements or at the edge of the covering thus formed. Furthermore, such in-fill panel elements have a trapezoidal shape so that they are able to bridge the gaps between the cylindrical and the conical portion of the airplane fuselage. During the fitting of the airplane, these in-fill panel elements are used when required. The known in-fill panel elements are releasably fastened to a longitudinal side of the panel element by means of an additional clamp-like connection element. A disadvantage of the known fastening method is that an additional connection element is required for the connection of the in-fill panel element to the panel element. Furthermore, the known connection element cannot prevent that upon the local application of force upon the panel elements, for example by the passenger supporting during boarding or loading the luggage, an offset with respect to adjacent panel elements occurs, which has a visually unfavorable effect and, moreover, leads to an undesired clattering in the case of material fatigue.

It is therefore the object of the present invention to further develop a device for fastening an in-fill panel element to a panel element of a covering for an aircraft in such a manner that a safe and dimensionally stable releasable connection is guaranteed while the mounting is simple.

In order to solve this object, the device according to the invention is characterized in that a transverse pin is arranged at least in the end portion of a longitudinal side so that a hook element arranged in the corresponding end portion of the other longitudinal side is able to clampingly engage with a hook opening such that a covering surface of the in-fill panel element is arranged so as to be even with a covering surface of the panel element.

The particular advantage of the device according to the invention consists in that the mounting is simplified by the fact that, on the one hand, no additional connection element is required and that, on the other hand, the mounting by means of the hook/pin connection is self-explaining. Because of the fact that the transverse pin and the hook element are arranged in an end portion of the abutting longitudinal sides, this results in a two-point fastening that guarantees a flush arrangement of the adjacent panel elements (panel element and in-fill panel element) which is stable over a long time.

According to a preferred embodiment of the invention, the hook element is connected integrally with the in-fill panel element whereas the transverse pin is allocated to the panel element and forms part of a fastening element for fastening the panel element to a stationary bearing profile of the airplane. Advantageously, the transverse pin has an extended configuration so that it is configured so as to be accessible for the hook element on a side facing the longitudinal side of the panel element. Advantageously, a transverse pin serving another purpose is utilized so that upon the manufacturing of the in-fill panel element, only an adapted hook element has to be formed integrally thereto. Thereby, the use of material can be substantially reduced which leads to a reduction of weight. Moreover, the fact that the material of the hook element is the same as that of the in-fill panel element results in an improved quality with respect to the demands on fire protection.

According to an embodiment of the invention, the hook element is formed integrally to an extension laterally projecting from a longitudinal side of the in-fill panel element, the hook openings of the hook element in the end portions of the longitudinal sides being respectively oriented outward from the center. Preferably, the hooks extend on a common straight line. The hook openings have a tapering configuration so that only, after a first hook element has been put on a first transverse pin by displacing the in-fill panel element in the mounting plane, the second hook element can be brought into engagement with the second transverse pin. Upon displacing the in-fill panel element in the mounting plane, the opposed hook elements are simultaneously clamped with the corresponding transverse pins so that in longitudinal direction of the longitudinal sides of the adjacent panel elements, a clearance-free and safe fit is guaranteed.

According to an embodiment of the invention, the extension of the in-fill panel element comprises a clamping nose spaced from a base of the extension, said clamping nose clampingly encompassing the upper edge of the longitudinal side of the panel element when the adjacent longitudinal sides of the in-fill panel element and the panel element abut each other, and thus effecting that the adjacent panel elements are free of any clearances in transverse direction to their longitudinal sides. Advantageously, the clamping nose forms part of the hook element so that the material use can be further reduced.

According to an embodiment of the invention, the in-fill panel element is configured as an injection molded part free of undercuts and thus permits a simple provision of a fastening means.

Hereinafter, an embodiment of the invention is explained in detail with respect to the drawings.

In the Figures:

FIG. 1 shows a perspective partial view of the edge portion of an in-fill panel element and a panel element in mounting position, and

FIG. 2 shows a side view of the in-fill panel element.

In FIG. 1, an edge portion of a panel element 1 forming part of a covering of an aircraft, particularly an airplane, is illustrated. Such a panel element 1 is described, for example, in DE 197 30 269 A1 and the not prepublished German Patent Application 100 63 035, respectively, and preferably comprises, as plane portion, an air shower segment and a reading light segment. Usually, the panel element 1 is fastened, at its opposed transverse sides 2, to a bearing profile not illustrated and extending in longitudinal direction of the airplane fuselage. To this end, the panel element 1 comprises fastening elements being able to be brought into engagement with the bearing profile. The fastening elements are arranged in an end portion of the transverse sides 2 and thus in an edge portion 3 where the opposed transverse sides 2 of the panel element 1 as well as the longitudinal sides 4 of the panel element 1 extending vertically thereto converge. Substantially, the panel element 1 has a well-like configuration, with a covering surface 5 facing the cabin of the airplane from the edge of which the opposed transverse sides 2 and longitudinal sides 4 project in opposite direction of the cabin. Usually, the covering surface 5 comprises recesses into which the air shower segment as well as the reading light segment are able to be installed.

Part of the non-illustrated fastening element of the panel element 1 are transverse pins 6 extending vertically to the longitudinal side 4 of the panel element 1 in the opposed edge portions 3. The transverse pin 6 has such a length that a free end 7 thereof is arranged in immediate proximity of an inside 8 of the longitudinal side 4. Thus, the transverse pin 6 is accessible for a hook element 10 formed to an in-fill panel element 9 from a rear side of the panel element 1. Like the panel element 1, the in-fill panel element 9 is rectangular while forming a covering plate 12 and comprises a longitudinal side 11 corresponding to the longitudinal side 4 of the panel element 1. Since the in-fill panel element 9 serves only for filling the tolerance of the panel elements, a transverse side 13 extending at right angles to the longitudinal side 11 is substantially shorter than the transverse side 2 of the panel element 1. Moreover, the opposed transverse sides 13 of the in-fill panel element 9 may have different lengths so that the in-fill panel element 9 has a trapezoidal configuration for evening out the spatial asymmetries of the airplane fuselage.

In an opposed end portion of the longitudinal sides 11 of the in-fill panel element 9, a base 15 rises from a narrow edge 14 of the longitudinal side 11 to which an extension 16 with the hook element 10 is annexed transversely to the longitudinal side 11. Spaced from the base 15, the extension 16 comprises a clamping nose 17 that, in mounting position, clampingly comes into abutment at the inside 8 of the longitudinal side 4 of the panel element 1. The clearance between the base 15 and the clamping nose 17 is dimensioned such that the longitudinal side 4 of the panel element 1 is arranged without any tolerance in the recess formed in this manner.

Simultaneously, the clamping nose 17 forms one of two spaced hook inner surfaces 18 of the hook element 10 between which a hook opening 19 is formed. At least one hook inner surface 18 is broadened transversely to the narrow edge 14 towards a free end so that the hook opening 19 is configured so as to converge from a base point. The length of the hook inner surface 18 is greater than the diameter of the transverse pin 6 so that the mounting of the in-fill panel element 9 to the panel element 1 fastened to the bearing profile not illustrated can be performed as follows.

In a first mounting step, a hook element 10 arranged in an end portion of the longitudinal side 11 is brought into engagement with the corresponding transverse pin 6 of the panel element 1 and displaced to the base point of the hook opening 19. Thereby, the other hook element 10 of the in-fill panel element 9 comprising a hook nose 20 can be brought into a plane between the transverse pin 6 and the covering surface 5 of the panel element 1 at an opposed end of the longitudinal side 11. In a subsequent mounting step, a displacement is performed in longitudinal direction of the longitudinal sides 4, 11, the hook element 10 arranged at the other end of the longitudinal side 11 being brought into engagement with the corresponding transverse pin 6 and the hook element 10 arranged at the one end of the longitudinal side 11 being also brought into a clamping position with respect to the transverse pin 6 while removing the base point of said hook element from the transverse pin 6. The in-fill panel element 9 is now arranged in press fit with respect to the panel element 1, the transverse pin 6 being clampingly retained in the hook opening 19 and the clamping nose 17 clampingly abutting on the inside 8 of the longitudinal side 4. Now, the covering surfaces 5 and 12 are in abutment so as to be even with each other. Because of the fact that the fastening of the in-fill panel element 9 to the panel element 1 is effected at opposed end portions of the longitudinal sides 11, a robust and dimensionally stable connection is guaranteed.
