The invention relates to a self-drilling screw (10) made of an austenitic or other stainless steel, comprising a shaft having a thread-forming region and a drilling tip (16). The shaft (12) is made of an austenitic or other stainless steel as one piece and is provided with a galvanically applied thin layer (20) at least in the area of the tip, whereby the area provided with the layer (20) is harder than an uncoated area, wherein the thin layer (20) has a pearl- or columnar-structured surface, a layer thickness of at least 2 µm and preferably up to 30 µm, and a hardness in a range of 500 to 1500 HV0.3. The self-drilling screw (16) is easier to produce than a common self-drilling screw, in which the drilling tip is made of a harder material than the shaft and is welded to the shaft made of stainless steel. The self-drilling screw (16) is thus a fully austenitic self-drilling screw made of a base material, which is provided with a hard coating. The coating ensures the drilling performance and the thread forming. In addition to the lower manufacturing costs, the corrosion resistance of the self-drilling screw (16) is a further advantage.

A self-tapping screw is described with a drilling part and a shaft (14) which is provided with a thread (12) and a core diameter (Dk). The drilling part has a drilling tip (20) which is arranged eccentrically in relation to a longitudinal axis of the screw, and is configured as a sickle tip (101) which has a primary cutting edge (30) and a secondary cutting edge (40). The primary cutting edge (30) is formed by the intersection of a cutting surface (60) and a main free surface (90) and extends from the drilling tip (20) parallel to the longitudinal axis of the screw. The secondary cutting edge (40) is formed by the intersection of the cutting surface (60) and an auxiliary free surface (70) and extends obliquely with respect to the longitudinal axis of the screw over the width of the drilling part. A hole with the core diameter (Dk) can be produced by way of the screw, into which the thread (12) cuts a counterthread. As a result of the joint action of the primary and secondary cutting edges (30, 40), the fibres are severed during the drilling operation when a workpiece is made from wood, so that the screw develops practically no splitting action.

The connecting arrangement is used to detachably connect two components (18, 20) that are provided with openings which are aligned with each other. A bolt (2) that is guided in a sleeve is provided in the bore of the one part (20) that is to be connected. The sleeve (4) and the bolt (2) protrude through the opening of the other component (18). An emergency opening mechanism is formed by forming a stop surface (14) in a recess on the bolt (2), said stop surface forming an angle (W) of less than 90 degrees and in particular less than 45 degrees with the axis of the bolt (2). A leaf spring (6) that is fixed to the sleeve (4) is shaped at the spring end (12) such that the stop surface (14) forms a positively engaging stop with the spring end (12). The angle (W) and the spring force of the leaf spring (6) are selected such that when a triggering force that exceeds the clamping force of the leaf spring (6) acts axially on the bolt (2) in the direction of the opening, the leaf spring (6) is forced apart and thus disengaged from the stop surface (14).
The device includes pneumatic and hydraulic cylinders, a switch valve connecting the pneumatic cylinder either to an outlet channel or a pressure supply, and an actuating element to switch the switch valve into a second position connecting a control line, open to the environment until closed by reaching a setting limit, to a pressure supply via a throttle and the switch valve. A pressure control valve having a control chamber connected to the pressure supply is structured so that pressures in the control chamber and the control line act on first and second control surfaces in the first and second switch position directions, respectively. The actuating element relieves pressure on the control chamber to move the pressure control valve into the second switch position to connect a motor line and switch channel of the switch valve to the pressure supply, which switches the switch valve into the first position.

The fact that a portion of the suspension eye lugs is designed as a sloping ramp allows the main pin (40) to be deployed in the receiver of the other suspension eye lug by the action of the preload during the upward movement of the overhead storage bin (12) and its suspension eye lug into the mounting position.
The invention relates to a lock (20) on a luggage box (22), in particular in the cabin of an aircraft. The luggage box (22) has a closable lid (28) which is movable about an axis of rotation (26) and supports a latch bolt support (40) with at least one main latch bolt (30) and a closure housing (80) for holding at least the main latch bolt (30) for latching the lock (20). Either the luggage box (24) or the lid (28) receives or supports the latch bolt support (40) and the other receives or supports the closure housing (80). The lock (20) is or can be connected and has an actuating mechanism (100) which can be actuated manually in order to release the main latch bolt (30) from the closure housing (80) to unlock the lock (20). The main latch bolt (30) in the latch bolt support (40) is pivotably mounted and in the latched position of the lock (20) is gripped in a blocking receptacle (60) of the closure housing (80) and bears against a main closing surface (63) of said receptacle. A further auxiliary latch bolt (50) is mounted on the latch bolt support (40) and in the latched position of the lock (20) said auxiliary latch bolt can also be blocked in a more or less correct latching position relative to the main closing surface (63) by an auxiliary closing surface (68) formed on the closure housing (80). The main latch bolt (30) closes in the blocking receptacle (60) of the closure housing (80) by positive engagement, whereas the auxiliary latch bolt (50) closes with a gap (69). The auxiliary latch bolt (50) is movably mounted in the latch bolt support (40) and closes in the closure housing (80) with a gap (69) around it, wherein a rocker (54) having a pin (58) is associated with the auxiliary latch bolt (50), which pin engages in a recess (59) in the auxiliary latch bolt (50) in the unlocked state of the lock (20), so that in the unlocked state of the lock (20) the auxiliary latch bolt (50) is retained in positive engagement in the latch bolt support (40), whereas when closing the luggage box (22) the rocker (54) is forcibly actuated by the closure housing (80) and thus the auxiliary latch bolt (50) is unlocked, but only when the closure housing (80) and the latch bolt support (40) are in a position relative to one another in which both latches (30, 50) can latch.
The invention relates to a lock for a luggage box installed overhead in the cabin of an aircraft, comprising a stationary housing and a cover that can move about a rotary axis. The lock comprises a locking pin device that can be mounted on the housing, comprising two locking pins (32, 32b) disposed in parallel, a catch (20) that can be mounted on the cover and that has two locking hooks (55, 55b) that can be pivoted about a pivot axis (22, 22b) for receiving the locking pins (32, 32b) for locking the lock (10), and a manually actuatable drive device (60) for jointly pivoting the locking hooks (51, 51b) away from the locking pins (32, 32b) for unlocking the lock (10). The drive device (60) comprises a gear rack (62) and a sliding element (64) that can be linearly displaced against the pressure of a spring element (70). The locking hooks (51, 51b) are each connected to the gear rack (62) or the sliding element (64) by a knee joint (74, 74b) that is hinged to the closing hook (51, 51b) adjacent to the pivot axis (22, 22b) thereof in such a way that the lock can be opened again only by tensile force acting on the hinged point of the knee joint (74, 74b) on the locking hook (51, 51b). This allows the functions of fail-safe and positive locking, which are required in aero technics, in a simple manner, wherein positive locking is achieved in that the knee joints (74, 74b) can each be brought into an end locking position in which said joints are mechanically locked and thus automatically prevent the lock from opening due to overload or vibration.
Disclosed are a locking mechanism (100) and a lock (110). The locking mechanism (100) comprises a push-button (148) connected to a freewheel (154) via a traction cable, said freewheel being connected to a drive device (160) of the lock (110). A baggage compartment in the cabin of an airplane usually comprises two locks (110) of this type which can be unlocked by the push-button (148). A freewheel (154) arranged between the push-button (148) and the lock (110) ensures that the push-button (148) remains in a pushed position as long as each lock (110) allocated to the baggage compartment is not in a correctly locked position. It can be identified from the position of the push-button of the baggage compartment whether both locks of the baggage compartment are correctly snapped in.
The invention relates to a plastering system (10) for a façade of a building.

FASTENING SYSTEM FOR HANGING MOUNTABLE OVERHEAD CONTAINERS
The invention relates to a fastening system (10) for hanging mountable overhead containers (12) such as baggage compartments in an airplane. Said system comprises at least one pair of support eyes (20, 22) mounted on a support structure (14) or on an overhead container (12). The support eyes (20, 22) can be detachably connected to each other by a pin (30) that can be drawn back in a pin guide (40) and thereby spring-loaded in the exit direction. When the support eye (22) attached to the overhead container (12) is inserted into the support eye (20) having the pin guide (40) when installing said container, the pin (30) is unlatched in the pin guide (40) and automatically moves out into the support eye (22) attached to the overhead container (12). Using a lever joined (60) to the pin guide (40) by a hinge, the pin (30) can be moved out completely into an end position, and locked in said position. In order to remove the overhead container (12), the lever (60) must simply be pivoted back.
The invention describes a system for fastening a panel such as a sandwich floor panel to an underlying structure such as a seat rail of an aircraft by means of a screw connection with a facility for securing the screw connection against loosening of the screw (14) and nut (12) as a result of vibration. The screw (14) is provided with an end region (16) which is non-circular in cross section. A securing element (40) is rotationally fixedly connected to the nut (12) and is in elastically resilient and positively locking engagement with the non-circular end region (16). In this fastening system, the screw securing facility is decoupled from the threads of the screw (14) and the nut (12), and therefore permits a considerable number of tightening and loosening cycles of the screw connection. The nut (12) is a blind rivet nut which is fastened to the underlying structure. The screw connection brings with it only a small additional weight, such that the fastening system overall has a low weight and is particularly suitable for use in aircraft.
The invention relates to a self-tapping screw comprising a drive part, a thread part (30), a drilling part (40), and two blades (42) freely projecting transversely to the screw axis (12) on the drilling part (40). The boundary of each blade (42) facing the drilling tip (44) is designed as a cutting edge (48). The screw has a core drilling cone (50) on the main cutting edge (46) thereof, which core drilling cone has a height (S). The cutting edge (48) of each blade (42) extends at least partially axially at least into the area of the height (S) of the core drilling cone (50). The blades (42) drill a hole in a softer layer at a drilling diameter (110). When or before the drilling tip (44) begins to drill a core hole in an adjoining harder layer, the blades (42) hit the harder layer and break off. A passage shock to the blades (42) is thereby avoided, which passage shock would occur if the blades (42) were arranged at such a large axial distance from the drilling tip (44) that the blades first hit the harder layer when the core hole has already been completely drilled by the drilling part (40). Therefore, the breaking off of the blades (42) does not depend on the drilling pressure that the operating person exerts on the self-tapping screw.
The invention relates to a holding device (10) for use during the installation of a component (60) to be fastened vertically to a support structure (50) such as that of an aircraft, for example a cabin sidewall lining part. The holding device (10) comprises a hook (12) and an eyelet (14) receiving the hook, said hook and eyelet being designed so that they can be fastened to the support structure (50) or the component (60). The eyelet (14) has at least one elastically resilient element for the movable mutual support of the eyelet (14) and hook (12). The holding device (10) facilitates the fastening of a perpendicularly installed component (60). The elastically resilient element allows the component (60) to be pre-positioned in a nominal position.
