Further advantageous embodiments of the universal line holder are in the following claims explained.

In the drawing shows:

1 A basic module of the universal line holder according to the invention designed for mounting on an annular upper edge of a fuselage cell reinforcement structure,

2 the basic principle of the one-hole mounting of the universal cable holder,

3 a function module designed as a conductor carrier for electrical lines,

4 a basic module designed for mounting on an annular lower edge,

5 3 a perspective view of the universal line holder on an annular upper edge,

6 a schematic plan view of a fuselage cell reinforcing structure with a bore grid, and

7 a sectional view taken along section line VII-VII in the 6

In the drawing, the same constructive elements each have the same reference number.

The 1 shows a basic module, which is designed for mounting on an annular lower edge of a reinforcing structure of a fuselage cell.

The basic module 1 has two, approximately at right angles, that is, at an angle of 90 ° to each other arranged leg 2 . 3 on. With an anti-rotation surface 4 of the thigh 2 lies the basic module 1 on a ring frame top edge 6 a ringpants 7 which is part of a fuselage cell reinforcement structure, not shown, of an aircraft. With a mounting surface 5 of the thigh 3 lies the basic module 1 at the same time on a Ringpantsteg 8th at. The anti-rotation surface 4 and the fortification area 5 close according to the alignment of the thighs 2 . 3 of the basic module 1 also an angle of about 90 ° with each other. Basically - depending on the circumstances of the fuselage cell reinforcement structure - an angle between 10 ° and 170 ° between the anti-rotation surface 4 and the attachment surface 5 be provided.

In the thigh 3 is a mounting hole 9 introduced with a semicircular cross section into which a clamping bolt 10 with a corresponding semicircular cross-sectional geometry for final positional fixation of the basic module 1 on the ring frame 7 is pluggable. The clamping bolt 10 is by means of a flexible security tape 11 Captive with the basic module 1 connected. For the realization of the example shown Einlochbefestigung the basic module 1 at the ring frame 7 is beyond that in the representation of the 1 concealed cylindrical bore required within the ring frame.

In the thigh 2 of the basic module 1 is a catch organ 12 arranged for snapping or attaching a in the 3 displayed function module on the basic module 1 serves. Deviating from the attachment of the basic module 1 at the ring frame 7 by means of only one clamping bolt 10 can be provided for attachment, especially at higher strength requirements, several clamping bolts. According to the invention prevents the anti-rotation surface 4 an unintentional twisting of the basic module 1 irrespective of the single-hole attachment in the area of the attachment contact surface used in the exemplary embodiment shown 5 of the thigh 3 ,

The basic module 1 of the universal cable holder may be without prejudice to the in 1 Example described attachment to the ring frame 7 be attached to any components that have two sufficiently large contact surfaces for Verdrehsi cherungsfläche 4 and the fortification 5 feature. The contact surfaces can collide with each other at an angle other than 90 °. In this case, however, there must be an angle between the thighs 2 . 3 of the basic module 1 correspond as closely as possible to an included angle of the contact surfaces. For mechanical reinforcement, the basic module 1 have unspecified reinforcing ribs.

The 2 schematically illustrates the operation of an exemplary Einlochbefestigung the universal line holder on the ring frame 7 ,

The basic module 1 lies with the right-angled thighs 2 . 3 preferably over the entire surface of the ring frame 7 at. In the thigh 2 is the catch organ 12 arranged for locking connection of the functional module. For fixing the basic module 1 at the ring frame 7 is in this at the mounting initially a cylindrical bore 13 brought in. Subsequently, the basic module 1 positioned so that the clamping bolt 10 in the cylindrical mounting hole 9 of the basic module 1 and the hole 13 can be introduced. When the clamping bolt 10 completely into the basic module 1 is driven, thereby one in an end 14 a wedge-shaped thickening clamping tab 15 of the basic module 1 from the clamping bolt 10 pressed in the direction of the black arrow in a clamping position shown with the dotted outline view. This results in a jamming of the basic module 1 in the hole 13 of the ringpants 7 , The clamping strap 15 is an integral part of the basic module 1 educated. Between the clamping bolt 10 and the attachment opening 9 in the basic module 1 There is preferably a slight interference fit. Both the clamping strap 15 as well as the clamping bolt 10 have approximately a semicircular cross-sectional geometry.

Like from the 2 can be seen, the basic module 1 of the universal pipe holder in a prepared hole 13 by means of the one-hole fastening shown in a simple manner on a structural component, for example a ring frame 7 in a fuselage cell of an aircraft are preferably attached. The anti-rotation surface 4 ensures the position fixation of the basic module 1 without prejudice to the preferred one-hole attachment. The thigh 2 can in an alternative embodiment of the universal line holder to ensure an even firmer fit on the ring frame 7 in the end of the thigh 2 a holding hook shown with a dashed outline 2a having one leg of the ring collar 7 additionally encompasses or includes. This variant is used in particular in a ring frame made of a CFRP composite material.

to Attachment of the holders to the fuselage cell reinforcement structure has them a variety of holes for mounting on. The holes point each to a distance of 25 mm up to 500 mm, thereby always a sufficient minimum holder distance is given and at the same time sufficient flexibility given in terms of mounting location. On areal reinforcing structures can the holes are arranged in a bore grid, wherein the Mesh size of the grid is preferably selected between 25 mm and 500 mm.

The 3 shows a designed as a line holder for electrical lines function module that can be snapped onto the base module.

A in the embodiment shown configured as an electrical conductor carrier functional module 16 essentially comprises a cross member 17 with one below the cross member 17 arranged catch member 18 that with the catch organ 12 at the basic module 1 is latched. The locking between the locking member 12 and the catch member 18 can for example by the insertion of the locking member 12 in the catch organ 18 and subsequent rotation by 90 ° - similar to a so-called "bayonet" closure. "Alternative locking mechanisms between the functional module 16 and the basic module 1 by means of the catch organs 12 . 18 are also possible.

In both end areas 19 . 20 of the crossbeam 18 is each a support 21 . 22 arranged for the support of, for example, electrical lines or cable bundles. Below the supports 21 . 22 are the bushings 23 . 24 with a roughly rectangular cross-section. The parallel to a longitudinal axis of the cross member 18 running bushings 23 . 24 serve to accommodate cable ties, tensioned clamps or the like for final positional fixation of the lines on the support surfaces 25 the support 21 . 22 , The supports 21 . 22 each have two, V-shaped bearing surfaces, of which the sake of clarity, only one bearing surface 25 is provided with a reference numeral. In the break point of the V-shaped contact surfaces 25 is each a jetty 26 . 27 arranged. For fixing on the supports 21 . 22 Overlying cables or cable bundles is an unillustrated cable ties each through one of the bushings 23 . 24 passed through and tightened. The cable ties enclose the function module 16 arranged webs 26 . 27 the support 21 . 22 and the cables or cable bundles, whereby the position fixing of the lines takes place. Due to the V-shaped bearing surfaces 25 or mutually inclined bearing surface 25 an inserted line when tightening the cable tie always automatically in the lowest point, that is in the area of the webs 26 . 27 drawn.

Notwithstanding the in the 3 Illustrated design can be the function module 16 also be designed for receiving more than two electrical lines, cable bundles or the like. Furthermore, the functional module can also be provided only for receiving a line. In addition, it is possible to design the functional module so that it can also accommodate other lines, such as fiber optic cables, hydraulic lines, water and sewers, supply or exhaust air lines or the like and fix in position.

Furthermore, it is possible to use the functional module 16 For example, as a latchable adapter having a substantially cylindrical shape and with a through-going retaining hole, by means of which, for example, a conventional ring clamp with the base module 1 is connectable. The lockable adapter becomes simple with the basic module according to the above-described electric line adapter 1 locked. The one fixing foot with a bore having ring clamp is connected to a conventional screw with the locking adapter by a screw or the like. The ring clamp is secured on the locking adapter, for example by a non-circular recess in the Rastadapteroberseite against accidental rotation. The mounting of the ring clamp is in this case at least partially positively inserted into the recess. Alternatively, the rotation can also be done by a pin / hole combination, a multiple toothing between the mounting foot and the locking adapter. The multiple toothing has the particular advantage that the ring clamp on the locking adapter in any angular positions can be fastened, but is still secured against accidental rotation. In this way, for example, "bent", that is, for example, arcuate, branching lines fix in position.

Furthermore, it is possible to use two basic modules 1 at a distance of up to 1 m on a fuselage cell reinforcement structure, for example a ring frame. The functional module is designed in this case as a crossbar or mounting rail, whose end portions with the basic modules 1 are latched. On the Traverse one of the number of lines to be fixed corresponding number of supports is provided, the design of each of which 3 equivalent. The supports can be integral components of the traverse or, for example, be fastened by a latching connection on this. In this way, a larger number of preferably parallel lines can be fixed in their position by only two basic modules.

The 4 shows an alternative embodiment of the basic module, which is intended to be fastened to an annular lower edge or an inner side of a ring frame.

A basic module 28 again comprises a leg 29 and a leg arranged at right angles thereto 30 , The thigh 30 forms an anti-rotation surface 31 and the thigh 29 has a mounting surface 32 on. With the anti-rotation surface 31 lies the basic module 28 at an annular lower edge 33 on while the fortification area 32 at the Ringspantsteg 34 of the ringpants 35 preferably applied over the entire surface. In the basic module 28 again is an approximately semicircular mounting hole 36 brought in. In the mounting hole 36 is a clamping bolt 37 with a likewise semicircular cross-sectional geometry can be introduced. The attachment of the basic module 28 by means of the clamping bolt 37 takes place in one in the 4 concealed cylindrical bore in the ring bridge 34 , as already described above (see. 2 ).

The backup of the basic module 28 against an unintentional change in position by rotation takes place by means of preferably the entire surface of the annular lower edge 33 adjacent anti-rotation surface 31 , The clamping bolt 37 is by means of a flexible security tape 38 Captive with the basic module 28 connected. The backup tape 38 is an integral part of the basic module 28 , which is preferably produced by injection molding with a thermoplastic material.

The 5 shows the basic module 1 with snapped electrical cable carrier as a functional module 16 (see. 1 . 3 ). The basic module 1 and the functional module 16 together form a universal wire holder 39 , The basic module 1 is by means of the clamping bolt 10 Despite the one-hole fastening, it is non-rotating on the ring frame 7 attached (one-hole clamp). The trained in the embodiment shown as an electrical cable carrier functional module 16 is on the basic module 1 attached, that is latched. The functional module 16 If necessary, it can also be returned from the basic module 1 be separated. This is particularly advantageous if a different type of line to be fixed with deviating cable diameter or a different number of lines. In this case, replacement with another functional module, for example in the form of one suitable for the other type of line, is sufficient. The functional module 16 is preferably either along the auxiliary line 40 or parallel to the auxiliary line 41 with the basic module 1 Lockable (x-axis, y-axis) to better accommodate different installation situations. By shifting (turning by 90 °) of the function module 16 parallel to the guides 40 . 41 and then latching to the base module 1 can be realized in a simple manner different installation directions (horizontal or vertical laying direction) of lines. By means of appropriately trained function modules 16 For example, electrical data lines, fiber optic lines, power lines, hydraulic or compressed air lines, water or sewer lines can be routed and secured.

Furthermore, it is possible to form the latching connection so that the functional module 16 at any angle to the basic module 1 can be plugged or latched with this, to other laying angles of the lines with respect to the course of the longitudinal axis of the ring frame 7 , which deviate from 0 ° or 90 °, respectively. The locking connection between the basic module 1 and the functional module 16 is designed so that in addition an unwanted rotation of the functional module 16 on the basic module 1 safely avoided. This can be done, for example, by a stylus in the function module 16 achieved by the latching process in a hole in the base module 1 is introduced. Furthermore, the rotation, for example, by a non-circular recess in the base module 1 be reached, in which an appropriately trained increase in the functional module 1 after the latching operation at least partially positive fit. In addition, the rotation after locking can also by a multiple toothing between the base module 1 and the functional module 16 will be realized.

Due to the two-part modular design of the universal cable holder 39 however, with a reduced number of individual components, it can still be used flexibly in a wide variety of different applications for attaching leads of all kinds to the aircraft fuselage trunk reinforcement construction. Here, only a relatively small number of design variants of the basic module needs 1 . 28 held the who, whereas the actual adaptation to different requirements in the line attachment is done by different functional modules.

For the attachment of lines of all kinds of Ringspanten are, for example, in the 1 . 3 shown exemplary embodiments of the basic modules 1 . 28 already sufficient. Through a variety of only differently designed functional modules 16 Nevertheless, a large number of applications in the attachment of lines of all kinds to the fuselage cell reinforcement structure can be covered.

The 6 shows a plan view of a fuselage reinforcing structure of an aircraft with a hole grid introduced therein for the variable-location attachment of the universal cable holder.

A fuselage cell reinforcement structure 42 has a circumferential ring frame 43 with two horizontally mounted cross beams 44 . 45 on. The crossbeams 44 . 45 have in the illustrated embodiment, a double-T-shaped cross-sectional geometry with a vertical profile web, a profile base and a profile crown. The ring frame 43 with a somewhat S-shaped cross-sectional geometry is with a fuselage cell skin 46 firmly connected. The crossbeams 44 . 45 are part of one in the 6 Not shown floor scaffolding of the fuselage of the aircraft.

In the ring frame 43 as well as the crossbeams 44 . 45 are a variety of holes, of which the sake of clarity, only a few holes 47 are provided with a reference numeral introduced. The holes 47 are preferably uniformly spaced from one another in the components of the fuselage cell reinforcement structure 42 arranged, but can also be introduced in a deviating hole pattern. In each of these holes 47 can be a basic module 1 . 28 be locked by means of the above-described Einlochbefestigung. The holes 47 each to each other - depending on the surface area of the respective component of the fuselage cell reinforcement structure 42 - a distance between 25 mm and 500 mm. For sufficiently large components of the fuselage cell reinforcement structure 42 the holes may deviate from the appearance of the 6 also two-row or multi-row (grid-shaped) be introduced into the components. Accordingly, the mesh size of the grid amounts to between 25 mm and 500 mm. The bore diameter is in each case between 1 mm and 10 mm, but preferably 5 mm.

The universal line holder according to the invention 39 can be due to the previously introduced holes 47 or the hole grid to save time. In addition, the universal cable holder can be 39 due to or through the entire fuselage cell reinforcement structure 42 To attach extensively Bohrungsrasters largely locally variable. For generating the hole grid or the multiplicity of holes 47 become the individual components of the fuselage cell reinforcement structure 42 , in particular in the ring frame 43 , in the stringers as well as in the crossbeams 44 . 45 , a variety of cylindrical mounting holes 47 for fixing the position of the basic modules 1 . 28 turned introduced. The hole grid or holes 47 prior to integration of the components to form the final fuselage cell reinforcement structure 42 already introduced in advance into the individual components. As a result, a locally flexible attachment of the Unversalleitungshalters 39 at almost every installation location in the area of the fuselage cell reinforcement structure 42 possible.

The 7 shows a schematic sectional view along the section line VII-VII in the 6 ,

The crossbeam 45 as part of the fuselage cell reinforcement structure 42 has a double-T-shaped cross-sectional geometry with a profile crown 48 and a profile bar 49 as well as a profile base 50 on. In the profile crown 48 , the profile bar 49 as well as the profile base 50 are a lot of holes 51 introduced, which is a preferably uniformly spaced hole grid for variable-location attachment of the universal line holder 39 form.

The universal line holder according to the invention 39 result in a high manufacturing flexibility at the same time significantly reduced number of vorzuhaltenden in the manufacturing process items and a simplified assembly process, resulting in a significant savings potential. The basic module 1 . 28 and the functional module 16 are preferably each made in one piece with a thermoplastic material by injection molding, which is still necessary provided with a fiber reinforcement.
