The invention relates to a device for vibration-free attachment of fittings, in particular of wall or floor elements in aircraft, to a structure, with a fastening element which is formed at one end for fixing to the structure and at the opposite end for receiving the internals.
In particular in airplanes it is necessary to have various installations such as e.g. Wall or floor elements, vibration-free or vibration-decoupled to connect to the supporting structure of the aircraft. However, such fasteners are also conceivable away from aircraft, where it comes to make vibrationally decoupled connections of various installations.
A damped attachment of a floor element with the aid of correspondingly shaped, damped feet is disclosed, for example, in JP 2007277884 A.
A similar construction is described in WO 2008/072982 A1, wherein a height adjustability can be achieved via a thread on the spacer, along which a corresponding element on which the floor elements rest can be moved.
Finally, US 2007/0262212 Al shows a fastening device for the arrangement of internals in an aircraft, where an adjustability is given in the vertical direction. A vibration damping is not integrated.
The object of the present invention is to provide an above-mentioned fastening device, which allows a vibrationally decoupled and adjustable connection of internals, especially in aircraft. The weight of the fastening device should be as low as possible, especially when used in aircraft. Disadvantages of known fastening device should be avoided or at least reduced. • «*« * *

The object of the invention is achieved by an above-mentioned fastening device, wherein the opposite end of the fastener slidably mounted in a connectable with the male internals spacer sleeve with slot-shaped cross-section and is designed for fixing to the internals, and at least one damping element for arrangement between the structure and the internals is provided. Due to the displaceable mounting of the fastening element in the spacer sleeve with slot-shaped cross-section is a Einsteilbarkeit and thus tolerance compensation possible. When used in aircraft, such an adjustability is permitted in the aircraft longitudinal direction and to compensate for tolerances also necessary. The vibration-free or vibration-decoupled fastening is made possible by the at least one damping element.
Advantageously, one end of the fastening element is formed by a base or can be connected to a base, which base is designed for displaceable mounting in a rail profile arranged on the structure. The rail profile is arranged on the structure or is already integrated therein and the fastening element can be placed in correspondingly desired positions relative to the fixtures to be fastened therein. With the displaceable mounting of the fasteners in the rail profile a coarse arrangement of the internals is achieved. The fine adjustment to compensate for tolerances via the above-described spacer sleeve with slot-shaped cross-section.
Vorteilhaferweise a fixing device for fixing the base of the fastener is provided in the rail profile. Depending on the design of the rail profile and the base of the fastener, this fixing can be designed differently.
For example, the fixing device may be formed by a wedge piece which can be latched into corresponding recesses in the rail profile. In this case, the wedge piece is designed corresponding to the recesses in the rail profile and can be attached to the rail section on the rail profile. It can be attached to the rail section. The desired position at which the fastening element is to be placed should engage in the rail profile and prevent a displacement of the fastening element.
According to one embodiment of the fastening device, the fastening element is formed by a screw bolt with a screw head and a thread. This is a particularly simple and inexpensive, as well as relatively light in weight embodiment. Of course, the fastener may also be formed by a bolt formed integrally with the base with a thread at its free end and a nut screwed onto it.
Preferably, the at least one damping element is arranged around the spacer sleeve in order to achieve the vibration-technical decoupling. Of course, the spacer sleeve itself could be made of a damping material or coated with such.
At least two damping discs are preferably provided as the damping element, which are preferably anchored to the spacer sleeve. Such anchoring may be formed by corresponding anchoring elements on the spacer sleeve, which penetrate into the elastic material of the damping discs. This arrangement enables a simple and efficient decoupling of any vibrations occurring.
It is advantageous if the damping discs are formed of silicone rubber. Silicone has good processability and optimal damping properties.
In order to prevent an unwanted solution of the attachment of the fixtures on the fastener, the bolt may be provided with a rotation. Such protection against unwanted solution of the bolt can be formed for example by a known snap ring.
To ensure a force flow to the structure in the form of a positive connection, two discs with a ribbing to the * * • # • * * * * * * * ft * ft * * ft * * # * * * * * * * * * * «·« »&Lt; "Ft" * - 4 - be arranged to each other oriented surfaces.
The bolt of the fastener, act on the higher forces is preferably formed of steel.
Advantageously, the rail profile is made of light metal, e.g. Aluminum, formed.
In particular, in the attachment of wall elements to a structure, it is advantageous if one end of the fastening element is formed by a profile piece, for example T-profile, or can be connected to such a profile piece, which profile piece can be connected to the structure. Instead of the profile piece, the end of the fastening element can also be connected directly to the structure. The structure can be formed from any profile or have only a straight surface.
The opposite end of the fastener is connected via the spacer sleeve with the internals, in particular the wall element.
The present invention will be explained in more detail with reference to the accompanying drawings, which show embodiments of the fastening device.

1 and 2 shows an embodiment of a fastening device 1 for the attachment of internals 2 in the form of a Bo-denelements 3, at a distance d from a structure 4, for example in an aircraft. Fig. 1 shows the arranged on the internals 2 fastening device 1 transverse to the longitudinal direction of the aircraft, Fig. 2 shows the fastening device 1 seen in the longitudinal direction of the aircraft. The fastening device 1 consists of a fastening element 5 with an end 6, which is designed as a pedestal 6 ', which is designed to rest against the structure 4. The one end 6 or stand 6 'opposite end 7 of the fastener 5 is for receiving the fittings 2, in particular of the bottom member 3, formed accordingly. For adjustability of the fastening device 1 in the horizontal direction, that is to say in the plane of the structure 4, the pedestal 6 'of the fastening element 5 is displaceably mounted within a rail profile 14 arranged on the structure 4. About this rail profile 14 thus takes place a coarse displacement of the fastening device 1. The rail profile 14 may of course also formed integrally with the structure 4 and be integrated in this. To fix the pedestal 6 'in the rail section 14, a corresponding fixing device 17 may be provided. This fixing device 17 may be formed by a wedge piece 18 which engages in corresponding recesses 19 in the rail section 14. By fastening the fastening element 5, the base 6 'from below and at the same time the wedge piece 18 is pressed from above against the rail profile 14, whereby the rail profile 14 clamped and a force flow in the structure 4 is made possible.
To compensate for tolerances, the opposite end 7 of the fastening element 5 can be connected in a spacer sleeve 21 with an elongated slot, which can be connected to the male housings 2 *. «· · I I I I I I I I I * * * * * * * * * * * * * * *
Cross-section (see Fig. 4) slidably mounted and formed for fixing to the internals 2. Due to the shape of the spacer sleeve 21 and its arrangement on the bottom element 3, an adjustability in the longitudinal direction to compensate for tolerances is possible. On the other hand, transverse to the aircraft longitudinal direction and also in height, the fastening device 1 is not displaceable or adjustable.
To damp vibrations, at least one damping element 8 is arranged around the spacer sleeve 21, which may be formed here by two damping disks 9, 10 arranged on both sides of the internals 2 or of the bottom element 3. The damping disks 9, 10 are preferably formed of silicone rubber. For fixing the damping disks 9, 10 may be arranged on the outside of the spacer sleeve 21 anchoring elements 22 which penetrate into the elastic material of the spacers 9, 10 and thus fix them.
The fastening element 5 is formed, for example, from a screw bolt 11 which has a screw head 13 and a thread 12, via which the screw bolt 11 can be screwed into a corresponding thread 12 'in the base 6. Below the screw head 13 of the bolt 11, a twist protection can additionally be arranged, which is formed from a snap ring. In order to ensure the force flow to the structure in the form of a positive connection, two discs 15, 16, which are formed with a ribbing on the mutually oriented surfaces, can be arranged. In addition, a washer 20 may be arranged between the lower damping disk 10 and the fixing device 17 or the wedge piece 18. The said disk 16 with the ribbing and the washer 20 may also be provided with an anchoring element 23, which penetrate into the elastic material of the damping disks 9 and 10 and thus fix them. By anchoring elements 22 and 23, it is possible to provide the bottom element 3 together with the spacer sleeve 21, the damping discs 9, 10, the lower disc 16 with the ribbing and the washer 20. This results in a simplified and uncomplicated installation. ••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••
Both in the spacer sleeve 21 and the damping discs 9, 10, the disc 16 with the ribbing and the washer 20 is a slot containing the adjustment of the bottom member 3 relative to the fastener 5 allows (see Fig. 4).
The height h1 of the spacer sleeve 21 is preferably smaller than the sum of the heights h2, h3 of the damping disks 9, 10 and the height h4 of the fixtures 2 or of the floor element 3 to be fastened. This achieves optimum vibration-decoupling of the fastening device 1.
The bolt 11 and the pedestal 6 'of the fastener 5 are preferably formed of steel. To reduce the total weight, the rail profile 14 and the discs 15, 16 are preferably made of aluminum. The fixing device 17, in particular the wedge piece 18, as well as the possible washer 20 are preferably formed from steel due to the higher requirements in terms of strength.
By means of the fastening device 1 according to the invention, a vibration-technically decoupled and adjustable connection of installations 2, in particular in aircraft, is possible. In the assembled state, the power flow of the bias on the screw head 13 of the bolt 11 to the upper disc 15 with the ribbing and then to the lower disc 16 with the ribbing and continue on the spacer sleeve 21 and not on the damping elements 8. However, before the spacer sleeve 21 takes over the power flow, the damping discs must be 9, 10 each biased by about 0.5 mm by the bolt 11 and compressed to ensure a damping. Therefore, the distances or heights h2 of the upper damping disk 9 and the height h3 of the lower damping disk 10 and the height h4 of the bottom element 3 together must be greater than the height h1 of the spacer sleeve 21. The sum of these distances or heights preferably corresponds to the sum of Height hl of the spacer sleeve 21 and the distance h5. The spacer sleeve 21 is thus pushed down until it is present at the wedge piece 18 and the force flow at • ♦ * ft • * · · · · · · · · · · · · · · · · · This passes on. The distance h5 between the lower side of the spacer sleeve 21 and the lower surface of the washer 20 is for example 2 times about 0.5 mm. Thus, the damping discs 9, 10 are protected from excessive pressure, which could endanger the damping.
Fig. 5 shows a further embodiment of a fastening device 1 for fastening a wall element (not shown) to a supporting structure 4 (not shown) in an exploded view. In this case, two fastening elements 5 are arranged side by side and formed by a screw bolt 11 with a screw head 13 and a thread 12. The one end 6 of the fastening element 5 is designed for fixing to the structure 4. In the example shown, the ends 6 of the fastening elements 5 with a profile piece 24, in particular a T-profile, connectable, which in turn with the supporting structure 4 (not shown) can be screwed. The opposite end 7 of the Befestigungsseismente 5 is slidably mounted on the spacers 21 with slot-shaped cross-section and, for example via a corresponding mounting structure 25 with the internals 2, here a wall element 3 (not shown), connectable. As a damping element, two damping disks 9, 10 of correspondingly damping material, such as silicone rubber, provided. About discs 15, 16 with a ribbing on the mutually oriented surfaces a positive power flow is achieved to the structure. By the spacers 21 with slot-shaped cross-section adjustability is achieved to compensate for tolerances.t. The attachment structure 25 can also be designed for fixing two or more wall elements (not shown).
