A fastening system for suspended installation of stowage compartments, in particular in aircraft, includes a first fastening element, which fastens on a supporting structure, a second fastening element, which fastens on a stowage compartment, and a connecting arrangement, configured for surface-area fastening on the first fastening element. The connecting arrangement and the second fastening element each include a supporting eyelet for accommodating a fastening bolt, to fasten the connecting arrangement on the second fastening element. The first fastening element and the connecting arrangement each include a fastening surface for fastening on one another, and therefore a continuous insulation layer can be positioned between the fastening surfaces, or between the supporting structure and the first fastening element, for the purpose of insulating the supporting structure, in order for the supporting structure alone or together with the first fastening element to be insulated throughout in relation to the connecting arrangement.

A connection assembly between two structures, the assembly including an assembly of two eccentric rings, one of which, the external ring, is fitted on the other, being formed as an insert, a bore of the internal ring being configured to fix to one of the structures using a fixing element, and the external ring being accommodated and retained in a through-opening of the other structure, at least one of the eccentric rings being made from a deformable material in order to at least compensate for a play when it is compressed by two retention and compression elements during assembly. Advantageously, it is thus possible to benefit from a mechanical play which facilitates the assembly and to eliminate this play during a tightening operation of the fixing element in order to improve a transfer of loads between the two structures.

A device for compensating for tolerances between two components to be connected to one another may have a hollow-cylindrical base element. The device may also have a hollow-cylindrical compensating element which comes into a first threaded engagement with the base element. The device may also have a connecting element extending through a first cavity of the device for connecting the two components. The connecting element comes into a second threaded engagement with one of the components and/or a first nut element. A second nut element is arranged in a recess of the compensating element in such a way that it comes into a third thread engagement with the connecting element. When the connecting element is screwed into one of the components and/or into the first nut element, the second nut element, at least in portions, is axially movable independently of the compensating element and relative thereto.

Disclosed is a system for connecting two panels together. A recess is formed in the edge of one panel, and an insert is pressed into and held within the recess. The top of the insert includes holes for receiving epoxy, and epoxy conducting shafts and circuits formed on the outside of the insert assist in the encapsulation of the insert within the panel edge. The top of the insert includes an aperture formed such that a fastener can be received into a cavity formed in the recess and then driven to be secured into a fastener-receiving insert installed into the second panel.

A fastener includes a screw structure having threads and a dowel structure. The dowel structure includes a shank extending from the screw structure in an axial direction and connected to the screw structure, and a head engaged to the shank portion and disposed distally from the screw structure. A length of the dowel structure is greater than or equal to a length of the screw structure.

A tolerance compensation arrangement for fastening first and second components with automatic or self-acting compensation of tolerances in the spacing between the components. The arrangement includes a base element having first and second metal elements with inner threads. An adjustment unit includes a threaded sleeve with an outer thread and a dragging unit at least partially arranged in the threaded sleeve. The outer thread forms a first thread pairing of a first thread direction with the inner thread of the first metal element. A fastening screw can be screwed into the inner thread of the second metal element via a second thread pairing of a second thread direction opposite to the first thread direction. The fastening screw can be connected to the adjustment unit via the dragging unit so that, during the rotation of the fastening screw, the adjustment unit co-rotates and is moved into abutment with the first component.

A locking mechanism comprises an S-shaped locking member which comprises respective locking hooks arranged at the end of opposed arms of the locking member. A pivot is arranged between the arms of the locking member. The locking member rotates around the axis (A) of the pivot. The locking mechanism further comprises a coupling for coupling the locking member to an actuator for rotating the locking member around the pivot axis (A). The coupling comprises at least one coupling element, an actuator coupling for coupling the at least one coupling element to the actuator and first and second drive couplings for coupling the at least one coupling element independently to each arm of the locking member for transmitting rotational movement thereto, such that failure of one arm of the locking member will not cause loss of drive to the other arm of the locking member.

A fitted bolt connection is provided for connecting at least two components to holes to be matched comprises a fitted bolt having a conical surface for arrangement in a hole in the first component, three or more separate cone segments each for arrangement between the conical surface of the fitted bolt and an inner peripheral wall of the hole in the first component, and clamping bolts each associated with the cone segments, by means of which the cone segments, independently of one another, can each be individually clamped between the conical surface of the fitted bolt and the inner peripheral wall of the hole.

An anchoring unit for a system, the anchoring unit having at least one first insulation layer and at least one second insulation layer. The anchoring unit furthermore includes a support layer for mechanically stabilising the insulation layers, the support layer being arranged between the first insulation layer and second insulation layer. The anchoring unit furthermore includes at least two screws, the screws being oriented in opposition to one another, a first screw being suitable for anchoring to the system and a second screw being suitable for anchoring to an anchor object. A first screw head of the first screw is in direct contact with the support layer. A screw shank of the first screw is arranged at least partially in the first insulation layer. A method includes fastening a system to the anchoring unit.
